Description

Method and apparatus for precise positioning and processing of fabrics, etc.

The present invention relates to a method and apparatus for precisely positioning and processing fabric pieces, in particular pattern pieces.

Methods and corresponding devices in which fabrics such as fabric webs or fabric pieces are, for example, manually or automatically (pre) oriented and properly oriented and fed to a processing step or to the conveyor of the apparatus are conventional Known in the art. The conveyor conveys the fabrics through the apparatus to various processing stations.

Both fabric pieces and pattern pieces made of any material that can be processed in the same manner as the fabric material are processed by such methods and corresponding devices. These include, for example, pattern pieces made of paper or plastic.

For example, it is known, for example, to automatically (pre) orient a correctly oriented fabric web prior to processing operations such as cutting the fabric web into pattern pieces. The orientation of the fabric web is performed mechanically, for example, by mechanically pulling the outer edge or file edge of the fabric to a divided guide bar. The guide bar specifies the correct orientation. In order to be able to perform such mechanical alignment, the fabric webs must have an edge that can be detected by the guide bar to pull the web to the desired position. This type of alignment means that it is impossible without an outer edge or pile edge, for example based on patterns or yarns or stitch courses. In addition, the fabric must be continuous as in the case of fabric webs. This type of alignment is not possible with fabric pieces. After correct orientation of the fabric web, it is possible to precisely cut the pattern pieces. The pattern pieces are then further processed (e.g., hemmed, folded and / or sewn) so that each pattern piece is automatically or as part of the device for further processing of the pattern pieces. Are transported manually.

In the case of automatic transfer, the pattern pieces are for example carried out by a suitable transfer and / or conveyor to a station where further processing may take place or the pattern pieces are transported further. Deviations from the correct orientation of the pattern piece that occurred during cutting of the (pre) oriented fabric are conveyed. The pattern pieces can also slip in the device during the process being delivered to the station so that they are no longer precisely aligned. This disables precise further processing of the pattern pieces, resulting in deterioration of product quality.

In the case of manual transfer where the operator takes a pattern piece from an upstream processing station or storage location and manually feeds it to the station in a (pre) oriented manner, the operator orients or positions the pattern piece by eye or using mechanical aids. Make it possible to determine and place it in the device. The inexperienced moment of new workers and even the inadvertent moments of some experienced workers has the disadvantage that the fabric cannot be processed in precise orientation, resulting in inaccurate orientation and positioning. These inaccuracies mean that the quality of the fabric intermediate or final product produced during the treatment is unacceptable and unacceptable.

Even if the pattern piece is delivered manually or automatically with pattern correct (pre) alignment, deviations from the correct orientation may occur while transferring the pattern piece to the processing station. For example, belt drives can be used as a conveyor to transfer pattern pieces through the conveying plate through the device, in particular thicker, where the pattern pieces slide on the conveyor and the correct orientation is not guaranteed during further processing. And / or in the case of flexible fabrics.

It is an object of the present invention to ensure that the pattern pieces fed to the processing station are precisely oriented and at the same time allow for the individual alignment of the fabrics or similar pattern pieces without the outer edges or the pile edges, while ensuring that particularly high quality products can be produced. And to provide an apparatus.

In order to achieve this object, the present invention proposes a method according to claim 1.

The pattern piece can be manually removed, for example, by an operator from an upstream portion of the device or from a storage location. Before supplying to the device, in particular to the station of the device, manual (pre) alignment or positioning of the pattern piece is performed, after which the operator manually feeds the pattern piece to the device, more specifically to the station.

Alternatively, the (pre) alignment or positioning of the pattern piece may be automatically performed, for example, in the upstream portion of the device where the pattern piece is (pre) aligned or positioned and then automatically fed to the device, more specifically to the station. It is possible to be done with. The station may be, for example, a transfer station for transferring a pattern piece through the device or performing any other task.

After the pattern piece has been fed, its orientation and / or positioning is checked and if necessary, a calibration step is performed. The checking step is preferably carried out in a non-contact manner, for example by sensory detection of the marks of the pattern piece. The marks are preferably present on the surface of the pattern piece, for example in the form of a pattern or in the fabric of a fabric, for example in the form of a yarn course or in the form of stitches, seams or similar fabric marks. The marks can also be formed in the form of patterns formed at different pile heights, for example by differences in the fabric. Marks are preferably detected by sensors.

Sensory detection can be accomplished by the naked eye or by suitable devices. The detected mark path is matched with a predetermined desired mark path. This is also done by people or by a suitable processor such as, for example, a data processor.

If the detection and adjustment are performed with the naked eye of the operator, the desired mark path may be formed, for example, by the transfer base on which the pattern piece is conveyed or displayed on the transfer base. The operator detects the deviation of the path of the pattern piece from the target path and determines the calibration value. The calibration value is determined by the operator based on the empirical values and can be transmitted to the calibration station, for example by manual input to a control element coupled thereto so that manual calibration is performed in accordance with the calibration value. If a deviation is detected by the sensors, the detected mark path is then sent to a processing station, for example, which then makes adjustments to the desired mark path, where the desired mark path is preferably stored in the memory of the processing apparatus. It is stored and ready to compare with the path of the marks. In the case of deviations, the processing device calculates the calibration specification sent directly to the appropriate receiver of the calibration station so that automatic calibration of the alignment is performed by the calibration station.

Alternatively, the calculated calibration specification can also be displayed on a display panel, such as a monitor, so that the operator can read these commands and manually enter them into a control element coupled to the calibration station. have.

The calibration device then performs a calibration step according to the calibration value or according to the calibration specification in order to ensure that the mark paths at least approximately coincide. Calibration can be performed, for example, by sending calibration values or calibration specifications to a controller of a suitable machine component, in which case the controller controls the machine component, performs calibration by appropriate machine action on the pattern piece and Make sure the pieces are aligned correctly.

Such readjustment of the mark path, and thus the pattern piece, makes it possible to precisely position the fabric in the device so that the fabric can be precisely processed at the processing station, in particular allowing high quality products to be produced.

Preferably, the non-contact check also makes it possible to align the edgeless pattern pieces so that individual and precise alignment and positioning can be performed based on patterns or yarn courses or similar fabric marks.

After processing, other checks and corrections may be performed if additional processing steps are followed in which the pattern piece must be correctly aligned. For example, it is possible to have single or multiple method steps repeated.

Alternatively, this object is achieved by the method according to claim 2.

The pattern pieces can be manually removed from the upstream portion of the device or manually from the storage location, for example, and fed to the device manually. Prior to feeding the device, in particular the station of the device, manual (pre) alignment or positioning of the pattern piece is performed.

Alternatively, it is also possible for the pattern piece to be automatically fed to the device or station after being (pre) aligned or positioned automatically. The station may be, for example, a transfer station for moving the pattern piece through the device or performing any other task.

After the first pattern piece is supplied, the pattern piece is processed at the processing station. Then, its alignment and / or positioning is checked. If deviations from the desired mark path are identified during the check phase, then calibration values or calibration specifications are determined that are sent from the processing station to the calibration station upstream. Then, the pattern pieces conveyed through the apparatus are aligned according to the calibration values or calibration specifications before they are later fed to the processing station. As a result, the subsequent pattern pieces are exactly aligned with respect to the processing step so that high quality products can be produced.

The checking step is preferably carried out in a non-contact manner, for example by sensory detection of the marks of the pattern piece. The marks are preferably present on the surface of the pattern piece, for example in the form of a pattern or in the form of a fabric of a fabric, for example in the form of a yarn course or in the form of stitches, seams or similar fabric marks. The marks can also be formed in the form of patterns formed by different fabrics, for example by different pile heights. Marks are preferably detected by sensors.

Sensory detection can be accomplished by the naked eye or by suitable devices. The detected mark path is matched with a predetermined desired mark path. This is also done by people or by a suitable processor such as, for example, a data processor.

When detection and adjustment are performed with the operator's naked eye, the operator recognizes the deviation of the fitting profile portion from the desired course and determines the calibration value. The calibration value is determined by the operator based on the empirical values and can be sent to the calibration station, for example, by manual input to a control element coupled thereto so that manual calibration is performed according to the calibration value. Alternatively, the detection and adjustment may be performed by the apparatus, in which case the detected mark path is then transmitted to the processing station, for example, then performing the adjustment on the desired mark path. The desired mark path is preferably stored in the processor's memory and ready for comparison with the path of the marks. In the case of deviations, the processor calculates the calibration specification sent directly to the appropriate receiver of the calibration station such that automatic calibration of the alignment of subsequent pattern pieces can be performed by the calibration station.

Alternatively, the calculated calibration specification can also be displayed on a display panel, such as a monitor, so that the operator can read this command and manually enter it into a control element coupled to the calibration station.

The calibration device performs the calibration step according to the calibration value or according to the calibration command such that the mark paths at least approximately coincide. Calibration can be performed, for example, by sending calibration values or calibration specifications to a controller of a suitable machine component, in which case the controller controls the machine component and the latter performs the calibration by appropriate machine action on the pattern piece. And the pattern pieces are aligned correctly.

Such a readjustment of the mark path, and hence of subsequent pattern pieces, makes it possible to precisely position the fabric in the device so that subsequent fabrics can be processed precisely at the processing station, in particular allowing high quality products to be produced.

Preferably, the non-contact check also makes it possible to align the edgeless pattern pieces so that individual and precise alignment and positioning can only be performed based on patterns or yarn courses or similar fabric marks. do.

After processing, other checks and calibrations can be performed, in which case it is possible to cause one or more method steps to be repeated.

Preferably, the method steps occur during continuous or discontinuous movement of the pattern piece.

Pattern pieces are conveyed through the device by a conveyor. Since the pattern pieces can be moved out of the device during movement, it is advantageous for the calibration step to be carried out during the transfer in order to precisely align the pattern pieces again before they reach other processing stations. The method steps can preferably be executed during the continuous movement of the pattern piece through the device so that the method can be executed economically. Very fast speeds of more than 20 m per minute can be achieved. However, if necessary, discontinuous movements can occur.

Preferably, the calibration is made just prior to feeding for the processing and carrying out of the processing steps. This ensures that the patterned pieces are fed to the processing station and processed inside thereof to be aligned correctly and that a particularly good quality product can be produced.

The sensor unit with at least one sensor or camera detects the marks of the pattern piece, and the sensor unit or camera compares the actually detected mark path with the nominal mark path stored in the computer's memory and automatically or manually corrects if there are deviations. Communicate with a computer that provides calibration specifications for

The pattern piece is conveyed by a conveyor past a sensor unit or camera and at least one sensor or camera detects the pattern or yarn course of the pattern piece. Alternatively, the sensor unit or camera can be transported past the pattern piece. The sensor unit or the camera communicates with the computer and transmits the data obtained to the computer. The computer is connected to the memory and can access the stored data, and at least one desired mark path is stored in a memory in which the computer adjusts the path of the marks. If there are deviations, the computer prepares the corresponding calibration specification and makes it available for the calibration to be performed. The calibration can be performed automatically by sending the calibration specification to the calibration station in the form of a corresponding actuation signal. Alternatively, the calibration can be done manually, in which case the calibration specification is displayed on a display panel, for example a monitor, read from the display panel, and then entered into a control element in communication with the calibration station. .

Preferably, the sensor unit or camera detects the actual path of deviation and the direction of deviation.

The correct mark path is prepared in this way. With regard to the direction, it is determined, for example, whether the deviation extends in the transverse direction with respect to the moving direction to the left or the right. The path is also detected rigorously, ie to what extent deviations exist. The path can be determined, for example, in mm. These records are compared with the desired mark path so that an accurate calibration specification can be generated with the relevant dimensions.

Preferably, the sensor detects the distance to the marks on the surface of the pattern piece.

This allows for example deviations from the desired mark path to be detected based on the progression of the pile height or other raised areas on the surface of the pattern piece.

Calibration values and optionally calibration specifications are manually entered into the control element and the alignment is calibrated according to the input. The operator can enter the determined calibration values into the control element and influence the alignment calibration.

Once the processor adjusts the paths and a calibration specification is generated, this calibration specification can preferably be read from the display panel and entered into the control element.

The control element is preferably coupled to the calibration station via a controller, which controls the calibration station in accordance with an input to the control element.

Deviations and / or calibration specifications are displayed on the display panel.

The calibration specification can be displayed on the display panel and read from the display panel, for example in the form of numerical values or comparable information. The operator can use these values for manual calibration by entering values into control elements that communicate with the calibration station. Alternatively or in addition, it is also possible for the deviations to be indicated and a calibration value can be determined therefrom.

Alternatively or additionally, it may be provided that the calibration specification is sent directly to a calibration station which automatically performs calibration in accordance with the calibration specification. As a result, no human intervention is required, and alignment correction of pattern pieces occurs in a fully automatic manner. The control system and / or display panel can also be provided as a safety precaution in case of failure of the automatic system or individual adjustments.

Preferably, the calibration is performed in both directions transverse to the direction of movement.

The pattern pieces can slide in both directions transverse to the direction of movement, so that correction in both directions is required to achieve accurate alignment.

The invention also preferably relates to a method for aligning the surface area or the edge area of a flexible web piece, in particular a fabric piece, in particular for manual or automatic calibration by a calibration station according to claim 1. Wherein the web pieces are preferably conveyed at least near the surface area or the edge area by the conveyor in a direction of movement parallel to the edge area and preferably on a driven conveyor of the conveyor relative to the support member of the conveyor. Pressurized and conveyed along the support member. Methods and apparatuses for aligning edge regions of flexible web pieces, such as, for example, a piece of textile material, are known from the prior art.

The term "flexible web pieces" is to be understood not only to include pieces of fabric material, but rather pieces of plastic, paper or similar materials may also be used.

Devices are known from the prior art in which the fabric material webs are aligned and hemmed at their longitudinal edges. After hemming, these webs are aligned and divided into pattern pieces of substantially rectangular shape. These pattern pieces are then realigned with the edges that have not yet been hemmed or folded and transported by the corresponding conveyor, with the aim of allowing the alignment to allow subsequent hemming and stitching of the edge area without causing a defective appearance. Is performed. A defective appearance occurs when the outer edges of the pattern pieces are not precisely aligned. Alignment devices and alignment methods are known in the art in which the file edge present in the pattern piece or web piece rising above the plane of the web piece is used as the alignment aid. Mechanical alignment means can be supported at this pile edge and can also align the pile edge with respect to the corresponding subsequent devices required for hemming and stitching, for example. However, without such file edges, sorting is generally impossible or can only be achieved with significant difficulty.

For example, it is not sufficient to align the first end of the edge area of the web piece and then transport such web piece by appropriate devices, since the alignment position set at the beginning of the web piece does not continue over the web piece. This is because the web fragments are flexible and the alignment achieved initially is lost while continuing to move as a result of the devices involved.

In particular, in the case of flexible web pieces where longitudinal hems have already been provided even before the web pieces are separated from the material web, which is subsequently provided by the corresponding transverse edges by changing the alignment position once the web pieces are separated from the material web. This poses a significant challenge in ensuring that high quality and accurate alignment is achieved in the edge area. However, such alignment is a prerequisite for further processing such as corresponding pattern pieces, since mechanical hemming and mechanical stitching of the heme may need to be performed after the alignment. The corresponding pattern piece is completed only after these tasks are completed. Errors in previous alignments result in poor quality of the pattern piece and are therefore unacceptable.

In order to ensure accurate formation of the surface area or edge area of the web piece in the form of a piece of fabric, an improvement is proposed.

In a conventional approach, the web pieces are first conveyed near the edge area by the conveyor in a direction of movement parallel to the edge area. The conveyor may, for example, consist of a circulating conveyor belt, which may also be operated via additional workstations of the production device. During certain uses, the conveyor belt is pressed against the support member (eg support plate) and transported along the support member. The support plate forms a counter-surface such that the edge region of the web piece is retained between the conveyor (conveyor belt) and the support member and conveyed along the support member in the direction of movement.

In the solution of the invention, if the alignment of the web pieces deviates further from the target alignment of the web pieces toward the conveyor, the incorrectly aligned portion or edge area of the web pieces acts towards or parallel to the plane spanned by the web pieces. It is provided that the deviation of the web piece is corrected to the target alignment by being moved by an appropriate amount away from the conveyor by a force of force, preferably a tensile force transverse to the direction of movement.

A piece of web slipped from the conveyor towards the conveyor can be pulled by a force that acts preferentially in the transverse direction with respect to the direction of movement causing the correct alignment.

Alternatively, with the solution of the present invention, the edge region of the web piece is fixed to the at least one second conveyor spaced from the conveyor and formed integrally and is conveyed integrally, wherein the alignment of the web piece is from the target alignment of the web piece. Further deviation towards the first conveyor causes at least one actuator to act as a compressive force on the area of the piece of fabric over the gap, so that the piece of fabric is appropriately removed from the first conveyor in the transverse direction with respect to the direction of travel and in the transverse direction with respect to the first conveyor. By being moved, it is provided that the deviation alignment of the web pieces is corrected to the target alignment.

During transport through the apparatus, the edge area of the web piece is fixed to the second conveyor. The second conveyor is preferably synchronized with the first conveyor such that the web pieces are uniformly transported through the apparatus. A gap is provided between the first and second conveyors spanned by the web pieces. As the deviation of the web pieces from the target alignment is detected, the actuator acts as a compressive force in this area and moves exclusively laterally relative to the first conveyor until the web pieces are moved to the target alignment.

Alternatively, in the solution of the present invention, the alignment edge is installed on the conveyor or mechanical part associated with the conveyor, or the support member forms an alignment edge set at the alignment position, such that the alignment of the web pieces is from the target alignment of the web pieces. Further deviations toward the web piece result in an incorrectly aligned portion or edge area of the web piece being pulled over the alignment edge and moved by an appropriate amount spaced away from the conveyor in the transverse direction relative to the direction of travel and in the transverse direction relative to the conveyor. Correction to the target alignment is provided.

According to the invention, an alignment edge is provided at the appropriate position of the machine frame, conveyor or other parts of the overall apparatus used for the purpose of aligning the web pieces. The alignment edge can be a stable edge. However, alignment edges may also be provided in the form of rods, flexible tension wires, and the like.

The support member itself can also form an alignment edge. Each alignment edge can be adjusted to a position suitable for the intended purpose. If the web piece is in an orientation that deviates from the target alignment, the web piece is pulled over the alignment edge and moved transverse to the direction of travel and transverse to the conveyor so that the deviation alignment of the web piece is corrected to the target alignment.

The term "transverse" is not to be understood in a right angle sense, but rather it is sufficient that the pulling motion occurs at an angle such that, for example, a portion of the tension component extends horizontally and another portion of the tension force extends vertically. In any case, a sufficient amount of tension must be applied to the web pieces to move the web portion to the desired degree. Preferably, if the alignment of the web pieces deviates further from the target alignment of the web pieces toward the conveyor, an incorrectly aligned portion or edge region of the web pieces travels over or in the direction of movement and is adjacent to the conveyor The support member may be pulled over the alignment edge of the recess and moved by a suitable amount spaced from the conveyor in the transverse direction with respect to the direction of travel and in the transverse direction with respect to the conveyor so that the deviation alignment of the web pieces is corrected to the target alignment at least one recess or It has one alignment edge.

In at least one of the projecting areas, preferably in two projecting areas, a recess or outer edge is provided which runs parallel to the direction of movement. The web piece is disposed, for example, over the corresponding recess or outer edge. The user can determine the alignment of the edge area of the web piece and move the web piece if the alignment of the web piece deviates from the exact target alignment of the web piece. If the web piece with deviation from the correct target alignment is closer to the conveyor with its edge area, the incorrectly aligned portion or edge area of the web piece is adjacent to the conveyor or over the outer edge running parallel to the direction of travel. Deviation alignment of the web pieces is pulled over the outer edge of the recess running parallel to, and in particular moved transversely to the direction of travel and transverse to the conveyor, thereby being moved (pulled) by an appropriate amount spaced from the conveyor. Is corrected. As the target alignment is achieved, the tension is no longer applied to the edge area of the web piece, but rather the latter is transferred further to the conveyor alone. Preferably, such configuration and alignment is provided on all the left and right sides of the conveyor so that a balance is achieved by the appropriate tensile force acting on the edge region of one side and the corresponding tensile force acting on the web piece of the other side, The alignment results in precise alignment of the web pieces.

Preferably, the alignment edge is aligned parallel to the direction of movement.

Such orientation is not essential, but is advantageous for the practice of the method.

Alignment is possible even in the case of non-parallel alignment, since the appropriate force effect can be applied to compensate for this and ultimately ensure the desired orientation.

Furthermore, it is also preferably provided that the tension is applied by a force effect at least approximately perpendicular to the strip of material.

This is advantageous in terms of achieving an accurate target alignment of the web pieces.

Very particularly, during the application of a force, in particular a tensile force, the means used to exert the force or tension is moved in an angular movement direction with respect to the direction of movement, preferably parallel to the direction of movement of the conveyor, or preferably in the direction of movement. Apply kinetic components to strips of material parallel to the direction.

This is not only selectively performed in narrow areas, but also over a larger area running substantially parallel to the direction of movement, and also ensures that the alignment can be performed discontinuously or continuously during the movement process.

The movement of the means or moving component in the direction of movement is adapted to the conveying speed of the conveyor to prevent the strip of material from wrinkling. The web piece proceeds parallel to the direction of movement and is perceived to be out of alignment by means of performing or monitoring the method and sensory or optically used for precise alignment of the web piece by the operation of technical means. It has a recognizable edge or outer edge or mark, line, or step.

In aspects of the equipment used, the above object is achieved by an apparatus according to claim 21.

The pattern pieces are preferably fed either automatically by the upstream part of the device or manually by the operator of the station. The conveyor is connected to or integrated in the station, and it is possible for the station itself to be a conveyor for receiving the pattern pieces or optionally the conveyor extends upstream from the in-feed station so that the pattern pieces can be removed from the station or It is already positioned so that it can be transported through the station to an adjacent conveyor. The pattern pieces are conveyed through the apparatus to the processing station by the conveyor.

The readjustment of the pattern pieces is generated by the check station and the calibration station to correct the alignment of the pattern pieces deviating from the target position by the apparatus during transport or during movement before the pattern pieces are fed to the processing station to be processed. This ensures a particularly good level of quality in the intermediate or final product.

The check station can be upstream from the calibration station, so the check step and subsequent calibration are performed first. Alternatively or additionally, a check station may be downstream from the processing station that checks the alignment of the processed pattern pieces and generates calibration specifications or calibration values for subsequent pattern pieces if there are deviations.

The check station enables contactless detection of the mark path, preferably sensory detection is performed by the naked eye or with appropriate equipment. The alignment of the pattern pieces can be checked at the outer edge or pile edge of the fabric pieces, but since the edge can be detected by the sensors, such an edge is not required, which is detected based on the patterns or similar marks. This can also be done. At the check station, the pre-detected mark path is compared with the desired mark path and a calibration value or calibration specification is determined.

The calibration value is provided while being checked by a person, who compares the mark path with the desired mark path and determines if the calibration value is to be set based on, for example, empirical values.

Alternatively, the comparison is performed by means of suitable technical means for data processing and a calibration specification is produced.

Then, the calibration of the alignment is performed by a calibration station using calibration values or calibration specifications to perform correct alignment of the pattern pieces.

The processing station produces a good quality intermediate or final product. The processing station may be, for example, a fastening device in which the pattern pieces are hemmed or stitched. However, any other processing step may also be executed.

Preferably, the check station compares the detector for detecting the path of the marks and the detected mark path with a desired mark path, preferably stored in an electronic memory, evaluates deviations and optionally provides a calibration specification. Has a processor coupled thereto.

The mark path detected by the detector is sent to a processor that performs a comparison with the desired mark path. The processor is coupled to a memory for storing at least one desired mark path for this purpose, the processor accesses data in the memory and compares the desired mark path with the mark path.

If there are deviations between the paths, the processor calculates the calibration specification and makes it available. The calibration specification is then sent to the display panel for display. Alternatively, the calibration specification can be provided as a corresponding control signal and sent directly to the controller of the calibration station.

The detector has a camera or sensor unit with at least one sensor.

The sensor unit or camera makes it possible to detect the mark path in a non-contact manner.

Preferably, the sensor is an optical sensor or a sensor that performs distance measurements.

Optical sensors can be used to optically detect the mark path. For example, colors or patterns can be detected. However, mark paths in the form of different pile heights at the surface of the pattern piece may also be detectable. They can also be detected optically. Alternatively, these marks can also be detected by distance measurements. To achieve this, a sensor is provided for performing distance measurements, which detects the distance to pile tips.

Preferably, the sensor is an optical sensor and the light source faces the sensor unit or camera and the pattern piece is between the sensor unit or camera and the light source while being transported through the device.

The light source can better identify the marks of the pattern pieces at which the sensor or camera is at least translucent as opposed to the sensor unit or camera projecting light through the pattern pieces.

Preferably, the processor has a computer with at least one desired mark path stored within the memory for comparison with the memory and the actual path of the marks.

Various desired mark paths may be stored on a computer, or new desired mark paths for new manufacturing lines may subsequently be programmed. These can then be selected according to the manufacturing line and used for comparison with the corresponding detected mark path.

The calibration station has a controller coupled to and controlled by the controller for inputting calibration values and optionally calibration specifications.

The calibration value determined by the operator or the calibration specification calculated by the processor may be manually entered into a control element that transmits a control signal corresponding to the control device. The calibration station performs a calibration step of alignment in accordance with the input.

Calibration can be performed, for example, by a suitable machine component, in which case the controller controls the machine component based on the calibration value or calibration specification so that the machine component can be calibrated by appropriate machine action on the pattern piece. And ensure that the pattern pieces are aligned correctly.

Preferably, the device has a display panel coupled to the check station and displaying the calibration specifications provided by the check station.

The display panel can be, for example, a monitor on which calibration specifications are displayed and which can be read later for input into a control element. This enables manual correction of pattern piece alignment.

Alternatively or in addition, the check station is coupled to the calibration station to communicate directly with it and the calibration specification is supplied directly to the controller of the calibration station as signals generated by the computer of the check station.

Thus, automatic calibration is performed without human intervention based on the calibration specification.

Furthermore, the invention preferably consists of at least one driven conveyor, in particular a conveyor with a mechanical frame for web pieces with a conveyor belt, as well as a support member for the conveyor, preferably a flexible web piece, especially a fabric piece. A device for aligning a surface area or an edge area of a device, in particular a calibration station for accurate alignment according to claim 21, wherein it is possible for the area located near the surface area or edge area of the web piece to be conveyed in the direction of movement. .

In order to ensure accurate formation of the surface area or edge area of the web piece in the form of a piece of fabric, an improvement is proposed.

On the sides of the equipment used for this purpose, the act of clamping the web piece at least approximately horizontal with the plane from a home position whose functional component lies outside of the plane covered by the web piece. An apparatus with at least one positioning means capable of being moved to a position is proposed, the positioning means being in particular for the purpose of carrying out the method according to any one of claims 12 or 18 to 20, in particular a conveyor. It is moved transversely with respect to the conveyor and transversely with respect to the direction of movement during the adjustment movement when in the working position, accompanied by the area of the web piece adjacent to.

The positioning means is moved from the open groove position to the working position for clamping the web piece. Then, the positioning means move transversely with respect to the direction of movement, accompanied by the area of the web piece, and apply force thereto until the web piece is moved to the target alignment.

Preferably, the device has positioning means on both sides of the conveyor.

This configuration allows alignment on both the left and right sides of the conveyor so that balance is achieved by appropriate forces acting on the edge region on one side and corresponding forces acting on the web piece on the other side, thereby achieving target alignment. Resulting in precise alignment of the web pieces.

On the aspects of the equipment used for this purpose, an apparatus with a second conveyor spaced apart from the conveyor is alternatively proposed, the second conveyor being between the second conveyor and the first conveyor spanned by the area of the web piece. It is possible to fix and transport the edge area of the web piece, leaving a gap, wherein the at least one positioning means securely fastened to the frame is such a plane from a groove position whose functional component lies outside of the plane covered by the web piece. Through the interlocking working position, the positioning means are moved into the gap during the adjusting movement, in particular accompanied by the area of the web piece across the gap, the web piece in particular according to claim 13 or 20 To carry out the method, the first conveyor is placed transverse to the direction of travel and transverse to the plane. And moving the second conveyor is the one person - a pair of belt or conveyor belt with a surface.

The web piece is held by the first and second conveyors and spans the material region between the retaining edge regions or material regions over the gap formed between the conveyors. In the case where the web piece has deviations from the target alignment, the positioning means can be moved or moved from the home position to the engaged working position through the plane spanned by the web piece, in particular accompanied by the area of the web piece spanning the gap. . The first conveyor allows the movement of the web pieces while the web pieces are secured to the second conveyor so that the web pieces are exerted by the pressure applied to the area with respect to the first conveyor in the transverse direction with respect to the direction of travel and in the transverse direction with respect to the plane. Is moved and corrected to target alignment.

Preferably, the apparatus has second conveyors on both sides of the conveyor and the positioning means.

This configuration allows alignment on both the left and right sides of the conveyor so that balance is achieved by appropriate forces acting on the edge region on one side and corresponding forces acting on the web piece on the other side, thereby achieving target alignment. Resulting in precise alignment of the web pieces.

In aspects of the equipment used for this purpose, the alignment edge may be provided in the machine frame or in a separate device frame, or the support member may have an alignment edge or be set in the alignment position, and at least one positioning means The positioning means can be moved from a groove position to a working position which engages through this plane, outside of a plane which is fastened to it and whose functional components are covered by the web piece, preferably lying on this plane. For the purpose of carrying out the method according to any one of the preceding claims, in particular, the adjustment movement in the transverse direction with respect to the plane passing through the alignment edge and in the transverse direction with respect to the direction of movement, accompanied by the area of the web piece adjacent to the conveyor. It is alternatively proposed to move while

By means of proper alignment of the alignment edges, which may also be formed by strips of wire or wires or the like, the means necessary to achieve alignment are provided. The support member itself can also have an alignment edge. If positioning occurs that deviates from the target alignment, the working position can be set by the positioning means, in which case the positioning means accompanies and affects the alignment of the web piece.

A portion of the web piece located near the surface area or edge area may be clamped between or between the support member and the conveyor.

The surface area or edge area may be conveyed in a direction of movement parallel to the edge area. In particular, the support member protrudes over the conveyor at both sides in the transverse direction with respect to the direction of movement and has two outer regions with an outer edge aligned with respect to the direction of movement, preferably an outer edge adjacent the conveyor and aligned parallel to the direction of movement. At least one of them has a recess, or preferably forms an outer edge aligned parallel to the direction of movement, in which case each outer edge is an alignment edge.

Particularly preferably, the movable support is positioned, held or fixed on the machine frame or on the support member or after the support member or below the contact plane of the support member for the web engraving, and at least of the positioning means relative to the movable support. A portion is set to the working position upon displacement by the intervening area of the web piece.

This facilitates the entrainment of the web piece upon activation of the positioning means, since the positioning means are given to the mating-surface by the movable support and are between the positioning means and the movable support of the strip of material.

Furthermore, it is preferable that the length of the displacement path of the positioning means from the home position to the working position can be adjusted for the purpose of accurately aligning the edge area of the web piece.

The support is fastened in a revolving manner to the machine frame or support member.

In one possible variant, the positioning means are embodied at the free end facing towards the web piece as a skid, roller or ram.

In one possible variant, the positioning means is a driven roller or a belt drive with rolls or driven and at least one freewheeling roller or only freewheeling rollers.

Particularly preferably, the power rotary drive is supported by a mounting block, in the frame as a drive for coupling means, in particular a positioning means connected by a drive belt or toothed wheel or a friction gear. And fixed to a drive shaft fixed to the frame, the positioning means being retained to be pivotable relative to the drive shaft.

The positioning means can be moved by a servo drive held in the frame.

The positioning means is pivotally held in the frame portion and can be moved to the home position or working position by the servo driver.

Preferably, the apparatus has respective support members on both sides after the conveyor with projecting areas, optionally recesses and positioning means.

In order to improve the guiding of the web pieces, the guiding member is preferably inclined downstream of the recess in the direction of movement that transitions to the protruding region without permission.

In one possible variant, the positioning means may be intermittently moved from the home position to the working position and back.

Preferably, the positioning means comprise a rotating actuator, in particular a belt drive, which is driven to circulate continuously at the beginning and at the beginning of the transition at least from the home position to the working position.

In addition, the actuator rotates in the same direction in the direction of movement, in particular slightly angular or preferably parallel thereto. Preferably, the apparatus in communication with a servo driver for moving the positioning means from the home position to the working position comprises in particular detection means for optical or sensory detection of the alignment of the web piece deviating from the target alignment. .

When the detecting means detects a deviation in the alignment of the web pieces, a corresponding signal is supplied to the servo driver of the positioning means, and the positioning means are moved to the working position, whereby the alignment of the web pieces is corrected to the target alignment.

The detection means is a sensor or a camera.

1 shows a schematic view of a method for accurately positioning and processing fabrics, in particular pattern pieces 1, by the following method steps:

(3) mechanically or manually feeding (pre) aligned and / or positioned pattern pieces 1 to the device 2 or station 9 of the device 2,

Preferably checking the alignment and / or positioning of the pattern piece by a sensor, preferably with reference to registration marks on the surface of the pattern piece or on the fabric of the pattern piece, wherein the path of the mark is compared with the desired mark path. ,

Determining (5) calibration values or calibration specifications and optionally providing a calibration specification for determining deviation of the mark path from the desired mark path, and

Sending (6) a calibration value or calibration specification to a calibration station 12,

Manual or automatic calibration (7) for alignment of the pattern piece (1) by the calibration station (12) according to calibration values or calibration specifications so that the determined mark path matches the desired mark path, and / or

Supplying the pattern piece 1 in the direction of movement 23 to a processing station 13 for processing the pattern piece 1, preferably to a fastening device in which the processing step is carried out, and

Optionally repeating one or more steps.

The pattern piece 1 may for example be manually removed from the upstream part of the apparatus or taken from the storage location. The pattern piece 1 is then manually aligned and / or positioned by the operator before the feeding step 3 to the station 9, and then the operator manually places the pattern piece to the station 9. Transport or release.

Alternatively, the (pre) alignment or positioning of the pattern piece 1 is performed automatically in an upstream portion of the device, for example, which is automatically delivered or fed to the station 9 after the pattern piece has been (pre) aligned. It is possible to be.

After step 3 in which the pattern piece 1 is fed to the station 9, its alignment and / or positioning is checked at the check station 11, and the calibration step 7 is necessary at the calibration station 12. Is performed accordingly. For this purpose, the pattern piece 1 is conveyed by the conveyor 10 via the apparatus 2, and the method steps preferably occur during the continuous or discontinuous movement of the pattern piece. The check step 4 and the calibration step 7 are particularly advantageous while the pattern pieces 1 pass through the apparatus, since the pattern pieces 1 can be moved in particular during movement, and the calibration step 7 is carried out before the treatment. In order to accurately align the pattern pieces 1, it may be necessary before step 8 that they are supplied to the processing station 13 for the execution of the processing step. Continuous movement makes it possible to carry out the process in particular economically, which makes it possible to achieve a speed of 20 m per minute.

Alternatively, the checking step 4 of the pattern piece 1 only occurs after processing in the processing station 13. This method sequence is not shown in FIG. Deviations of the marks from the desired mark path (e.g., seams created during the process of deviating from the target course) are detected after the process, and the calibration specification or calibration value is determined and sent to the calibration station 12. The calibration station 12 then performs a corresponding calibration on the subsequent pattern pieces 1 so that the subsequent pattern pieces 1 are correctly aligned upstream of the feed 8 to the processing station 13.

The check step 4 is carried out in a non-contact manner, for example by optical detection of the marks of the pattern piece 1. The marks are preferably on the surface of the pattern piece, for example in the form of a pattern or in the form of a fabric of fabric, for example a yarn course or in the form of stitches, seams or similar fabric marks and are optically detected. However, it is also possible that other detectors are also provided which can detect the marks in a non-contact manner. For example, it is also possible to detect marks in the form of different pile heights by distance measurements. To accomplish this, a sensor may be provided that performs distance measurements, which detects the distance to the pile tips. If no deviation is found during the check step 4, a calibration step 7 is not required and the process continues along the dashed line Y, so that the supply step 8 to the processing station 13 after the check step 4 is performed. ) Follows. Optical detection can be achieved with the naked eye or by suitable optical devices. The optically detected mark path is compared with a predetermined desired mark path. This is also done by people or by a suitable processor 15, preferably a data processor.

If detection and adjustment are performed by the naked eye of the operator, the desired mark path can be displayed, for example, at the transfer base or formed by the transfer base on which the pattern piece 1 is transferred from above. However, any other suitable implementation is possible for a person to visually compare the mark path with the desired mark path. The operator detects the deviation of the path of the pattern piece from the target path and determines the calibration value. This can be determined by the operator based on the empirical values and transmitted to the calibration station 12, preferably manually entered into the control element 20 coupled thereto so that the manual calibration step 7 can be carried out in accordance with the calibration values. have. Optical detection is preferably performed by a sensor unit 17 with at least one sensor or by a camera, the pattern piece 1 being conveyed by the conveyor 10 past the sensor unit 17 or the camera and Marks of the pattern piece 1 are optically detected. The sensor unit 17 or the camera preferably detects the actual path of deviation and the direction of the deviation so that the correct mark path is determined. With regard to the direction, it is determined, for example, whether the deviation extends transverse to the travel direction 23 on the left or the right. The path is also detected accurately, ie to what extent a deviation exists. The path can be determined, for example, in mm. These records are then compared to the desired mark path so that an accurate calibration specification can be created with the relevant dimensions.

The sensor unit 17 or camera communicates with the processor 15, and the detected mark path is transmitted to the latter. The processor 15 preferably has a computer 19 and a memory 16 coupled thereto, where at least one desired mark path is stored in which the path of the marks is compared. A plurality of different desired mark paths can be programmed and stored in the memory 16 and selected according to the product or manufacturing line for comparison.

If there are deviations, the computer 19 prepares the corresponding calibration specification and makes it available for the calibration step 7 to be carried out. The calibration step 7 is then automatically generated by the transmission of the calibration specification as a corresponding operating signal to the calibration station 12 which automatically executes the calibration step 7 according to the calibration specification, thus eliminating the need for human intervention. A fully automatic calibration 7 of the alignment of the pieces 1 takes place.

Alternatively, the calculated calibration specification can also be displayed on the display panel 22, which is a monitor, so that an operator can read this command and enter it into the control element 20 connected to the calibration station 12. The calibration specification can be displayed and read by the operator, for example in the form of numerical values or comparable displays. The control element 20 is preferably coupled to the calibration station 12 via its controller 21, which controls the calibration station 12 in accordance with an input to the control element 20. The control element 20 and / or display panel 22 may also be provided in an automatic calibration step 7, in which the control signal is provided as a safety precaution in the event of a failure of the automatic system or individual adjustment, for example. Routing can be done directly to the calibration station 12.

The calibration station 12 then performs a calibration step 7 according to the calibration value or according to the calibration specification such that the actual and desired mark paths coincide.

The calibration step 7 can preferably be carried out by sending a calibration value or calibration specification to the controller 21 of a suitable mechanical component, in which case the controller 21 is dependent upon the calibration value. The mechanical component is thus controlled in accordance with the calibration specification, the latter performing the calibration step 7 by appropriate mechanical action on the pattern piece 1 and ensuring that the pattern piece 1 is correctly aligned. Since the pattern piece 1 can slide in both directions transversely with respect to the movement direction 23 and a calibration step 7 in both directions is required, the calibration step 7 is performed in the movement direction 23. In both directions in the transverse direction. Only then accurate alignment can be achieved. Such a readjustment of the actual mark path, thus the pattern piece 1, makes it possible to precisely position the pattern piece 1 in the apparatus 2 so that the pattern piece 1 can be precisely processed at the processing station 13. Can, in particular, enable high quality products to be produced. Preferably, the check step 4 and the calibration step 7 are therefore executed immediately before the processing step such that the pattern piece 1 is fed in the correct alignment for processing.

The non-contact sensor check step 4 also makes it possible to align the edgeless pattern pieces so that individual and precise alignment and positioning is based on the patterns, or on the basis of yarn courses or similar fabric marks. It can only be performed in the field (1). The processing of the pattern piece 1 can be performed in any desired manner; For example, the hem may be sewn or the pattern piece 1 may be folded. After the processing, another check step 4 and a calibration step 7 can be carried out, followed by further processing steps in which the pattern piece has to be aligned correctly, and the method steps can be repeated as many times as desired.

2 shows a schematic structure of an apparatus 2 for carrying out the method according to claim 1, wherein the apparatus 2 is:

Station 9, in which the pattern pieces 1 are supplied in a (pre) aligned and / or positioned form manually or mechanically,

A conveyor 10 connected to the station 9 and optionally starting upstream from the station 9 for displacing the pattern piece 1 through the device 2,

The check station 11, in which the marks path of the marks of the pattern piece 1 can preferably be detected by the sensor and compared with the desired mark path, and a calibration value or calibration specification can be generated or generated,

A calibration station 12 for precise alignment of the pattern piece 1 according to the calibration value or according to the calibration specification, and

It comprises a processing station 13, preferably a fastening device, in which the pattern piece 1 is supplied in a precisely aligned and processable form.

The pattern piece 1 is preferably fed either automatically in a (pre) aligned form from the upstream part of the device or manually by the operator at the station 9.

The conveyor 10 is connected to a station 9, the station 9 itself being capable of being a conveyor 10 to which a pattern piece 1 is fed and optionally the conveyor 10 has already been positioned so that the station 9 By having an upstream end upstream from) the pattern pieces 1 can be transferred from the station 9 or through the station 9 to the adjacent conveyor 10.

The station 9 may also be any other station 9 for performing a processing step, for example. By means of the conveyor 10, the pattern piece 1 is conveyed to the processing station 13 via the apparatus 2, through or through the check station 11 and the calibration station 12. The check station 11 may alternatively be downstream from the processing station 13, not shown in the figure. The check step 4 takes place only after the processing of the first pattern piece 1 in this case. If a deviation from the target course is detected, a calibration specification or calibration value is transmitted from the processing station 13 to the upstream calibration station 12 so that calibration of the alignment occurs before processing.

The readjustment of the pattern piece 1 occurs at the check station 11 and the calibration station 12 so that the alignment of the pattern piece 1 moved from the target position by the device 2 during transport or during the movement is the pattern piece 1 It is calibrated before being fed to the processing station 13 which is processed into an intermediate or final product. This in particular ensures the high quality of the intermediate or final product.

3 shows a first variant of the apparatus 2. The check station 11 allows for contactless detection of the mark path. For this purpose, the check station 11 has a camera or sensor unit 17 with at least one optical sensor as detector 14. Thus, the moving pattern piece 1 can be detected. Since edges are optically detectable, it is possible to detect outer edges or pile edges based on which alignment can be performed, but this is not absolutely necessary, as optical detection is based on any pattern or similar marks. Because it can be performed. Alternatively, the marks can also be detected by distance measurements. To achieve this, a sensor is provided for performing distance measurements, which detects the spacing for the pile tips. Processor 15 of inspection station 11 coupled to detector 14 then compares the detected mark path with the desired mark path and a calibration specification is determined (5). This is done by suitable technical means for data processing, and a computer 19 connected to the memory 16 is used in this embodiment. The mark path detected by the camera or sensor unit 17 is transmitted to the processor 15, more specifically to the computer 19 contained therein. The computer 19 then performs a comparison of the mark paths with the desired mark paths stored in the memory 16, where various desired mark paths are stored in the memory 16 or new desired mark paths are followed for new manufacturing lines. It can be programmed as Thereafter, they are selected according to the manufacturing line and can be used for comparison with the corresponding detected mark path.

If the actual mark path deviates from the desired mark path, the calibration specification is calculated by the computer 19. The calibration specification is passed by appropriate technical means to the receiver of the calibration station 12 performing the calibration step 7 in accordance with the calibration specification. For example, the calibration specification is transmitted to the controller 21 of the calibration station 12 in the form of a control signal of the computer 19. In this case, the check station 11 is coupled to the calibration station 12 for direct communication. Thus, an automatic and accurate calibration step 7 is performed without human intervention based on the calibration specification.

The calibration step 7 may for example be carried out by means of a suitable mechanical component, in which case the controller 21 controls the mechanical component based on the calibration specification and the mechanical component is attached to the pattern piece 1. Corrective action (7) is carried out by appropriate mechanical action on and the pattern piece (1) is correctly aligned. If there is no deviation, the calibration step 7 does not occur. The pattern piece 1 is then supplied to the processing station 13. The processing station 13 may be, for example, a fastening device in which the pattern pieces 1 are hemmed, glued or stitched. However, it may also be a device for folding the pattern pieces 1 or performing any other processing aspect.

The processing station 13 produces an intermediate or final product of good quality. A second variant of the device 2 is shown in FIG. 4. Detection of the mark path and comparison with the desired mark path is performed at the check station 11 with the naked eye. The comparison is performed, for example, by indicating the desired mark path used for the comparison of the transport underlay from which the pattern piece 1 is conveyed from the desired mark path or by having a transport underlay. The operator detects the deviation of the course of the pattern piece from the target course and determines the calibration value. This calibration value can be determined by the operator based on experience values and sent to calibration station 12 by manual input to control element 20 coupled thereto so that manual calibration 7 is performed according to the calibration value. . The calibration station 12 has a control element 20 for this purpose.

A third modification is shown in FIG. Detection and comparison is carried out in the inspection station 11 as in the first embodiment, i.e. by the detector 14 (e.g. a sensor) and the processor 15, where the computer 19 of the processor 15 Is coupled to the display panel 22, and the calculated calibration specifications displayed on the display panel 22 are sent to the computer 19. The indicated calibration specification is read and manually entered into the control element 20 coupled to the calibration station 12. The calibration station 12 has a controller 21 coupled to the control element 20 and is equally controlled according to the input. A fourth modification is shown in FIG. Here, detection is performed with the sensors of the sensor unit 17 with the light source 18 opposite. During movement through the device 2, the pattern piece 1 is between the sensor unit 17 and the light source 18 and is illuminated by the light source 18 such that the sensor is for example the fabric of the fabric pieces 1. Marks in the fabric can be better detected.

Both fabric pieces and pattern pieces made of any material that can be processed in the same manner as the fabric material are processed by the method and apparatus. These include, for example, pattern pieces made of paper or plastic.

The device shown in FIGS. 7-11 preferably aligns the edge regions of the flexible web piece 102. Such a device can be used, for example, as a calibration station 12 for correct alignment in the device 2. The web piece is in particular a piece of fabric separated from the fabric web and has a quasi-rectangular base shape. The apparatus comprises a conveyor with a marked machine frame 104 for a driven conveyor 105, for example web pieces 102 having a conveyor belt and a support member 106 for the conveyor 105. 103). In this embodiment, the support member 106 is a plate. The web piece 102 is placed on this plate. A conveyor 105 in the form of a belt drive is placed on top of the web piece 102 so that the latter is pressed against the support member 106. The support member 106 is preferably a flat and smooth plate. Preferably, the conveyor 105, which is the conveyor belt of the belt driver, is combined at the upper side with spring support blocks 107 which resiliently bias the conveyor 105 towards the support member 106. These support blocks 107 are held in components of the machine frame 104. The visible portion of the machine frame 104 is an L-shaped inclined piece of sheet metal, one leg of which extends parallel to the extension of the support member 106, while the other leg is perpendicular to it. To extend.

A portion thereof located near the edge region 101 of the web piece 102 may also be retained clamped or clamped between the support member 106 and the conveyor 105 and moving parallel to the edge region 101. It is conveyed by the conveyor 105 in the direction 108. As can be clearly seen in FIGS. 7 to 11, the edge regions 101 are formed in a quasi wave shape to illustrate the alignment problem so that the edge regions are not aligned exactly parallel to the direction of movement. Rather, it extends from the conveyor 105 at different shapes and at different distances.

The support member 106 protrudes outwards through the conveyor 105 on both sides in the transverse direction to the direction of movement. Protruding areas are shown at 109 and 110. In this embodiment, recesses 111, 112 with outer edges 113, 114 extending parallel to the direction of travel 108 are provided in both the protruding regions 109, 110 and each conveyor 105. Adjacent to. Instead, the respective outer edges 115, 116 of the protruding regions 109, 110 of the support member 106 may suitably be used, in which case these outer edges 115, 116 also move in the direction of movement. May be oriented parallel to 108. In addition, each positioning means 117, 118 is in this embodiment an example in which its functional components lie outside the plane covered by the gap between the support member 106 and the conveyor 105 on this plane, for example, From the home position shown in FIGS. 7, 9 and 10, the positioning means are engaged with the plane to the working position shown in FIGS. 8 and 11 with the component positioned almost below the protruding region 109 or 110. It is indirectly fastened to the machine frame 104 over each outer edge 113 or 114 that can be moved or possibly also over the outer edge 115 or 116.

The positioning means 117 or 118 move transversely with respect to the direction of movement 108 and transversely with respect to the plane described above, in particular after the conveyor 105, in particular as clearly shown in FIGS. 8 and 11. Passing the outer edge 113 or 114 or 115, 116 at relatively close intervals therewith accompanying the area of the web piece 102 located at. Depending on the desired orientation, the edge area 101 or the edge area 101a overlying the conveyor 105 can thus be aligned with the positioning means 117 or 118. When the positioning means 117 moves from the position according to FIG. 7 to the position according to FIG. 8 or from the position according to FIG. 10 to the position according to FIG. 11, in order to accurately align the course of the edge area 101 as desired. Lateral forces are applied to the corresponding edge area 101 or area 101a of the web piece 102, which engages with the positioning means 117, 118 to move the area of the web piece 102 away from the conveyor 103.

In order to achieve reliable entrainment of the web piece 102, in particular the edge of the web piece 102, while the positioning means 117, 118 move from the home position to the working position, the pivot support 119 is provided with a support member. A part of the positioning means 117, 118 is pressed against the displacement path of the positioning means 117, 118 on the 106, in particular during movement to the working position, for example a movement as seen in FIG. 8. It is held in the vicinity of the recesses 111 and 112 on the front outer edges of these recesses in the direction of movement which presses the support downward in the transverse direction to the direction. The interposed edge region 101 of the web piece 102 is retained between the positioning means 117, 118 and the support 119 such that the desired movement of the edge region 101 is moved as clearly made in particular in FIG. 11. Occurs transverse to the direction 108. For the purpose of precise alignment of the edge regions 101, 101a of the web piece 102 the length of the displacement path from the home position of the positioning means 117, 118 to the working position can be adjusted by the operator, for example For example, a larger or smaller displacement is moved in accordance with the deviation of the outer edges of the edge regions 101 and 101a from the desired position.

In particular, the support 119 is fastened in a resiliently movable manner to the support member 106, in particular to the front edges of the recesses 111, 112 in the direction of movement 108.

This ensures that the support 119 is automatically moved during the displacement of the positioning means 117, 118 to follow the displacement path.

The figure does not show that the positioning means 117, 118 are implemented at its free end facing towards the web piece 102 as a skid, roller or ram. This is one possible design. In this case, however, the operation of the positioning means, i.e. the movement of the positioning means from the home position to the working position, is such that the respective edge regions 101, 101a located below the positioning means have the web pieces in the direction of movement 108. It should occur intermittently so that 102 can be properly pulled by the positioning means during movement to achieve accurate alignment.

Preferably the positioning means is a belt drive 120, 121 with a driven roller 122 and a freewheeling roller 123 through which the belt of the belt drive 120 or 121 is circulated and moved. do.

As a driver for the driven roller 122 of the positioning means 117, 118, the motorized rotary drive 124 is provided with frame parts, for example coupling means 125 (in this embodiment). Are held and fixed to the parts of the machine frame 104 connected to the drive shaft 126 via a drive belt). For this purpose, the drive shaft 126 also has a roller 127 rigidly connected to the shaft. The drive shaft 126 is supported and guided in the mounting block 128, which in turn is securely fastened to the parts of the machine frame 104. The drive shaft 126 is firmly connected to the driven rollers 122 of the two positioning means 117, 118 such that the belt drives 120, 121 are set to move by the rotation of the drive shaft 126. The direction of rotation of the coupling means 125 (drive belt) is indicated at 129. In addition, the positioning means 117, 118 can be moved by the servo driver 130 fastened to the machine frame 104. For this purpose, the servo driver 130 consists of an electric motor 131, which can be set to alternately run in a limited manner, for example, from side to side. Through the output shaft 132, the support disk 133 is rotated in a limited manner clockwise or counterclockwise about the axis formed by the output shaft 132. The components 138, 139 of the positioning means 117, 118 are connected to the drive shaft 126 on this support via coupling rods 134, 135 and connecting rods 136, 137. Can be turned around. Rotating the support 133 in one direction (for example, clockwise) by the driver 131 moves the positioning means 117 to the working position, and the entire element with the belt drive in the working position is for example 11, the freewheeling roller 123 is pivoted from the home position to the downwardly displaced working position. As a result of this movement of the support 133 the positioning means 118 located on the other side is raised. When the support 133 is rotated in the opposite direction, the positioning means 117 is raised, while the positioning means 118 is similarly lowered as a result of the freewheeling roller 123 being moved downward. By this arrangement it is ensured that the two positioning means 117, 118 cannot act simultaneously on the web piece, but rather only on each selected positioning means 117, 118 as determined by the user.

In order to achieve complete guidance of the edge regions 101, 101a of the web piece 102 even after passing through the recesses 111, 112, each obliquely positioned guide member 140 is moved. In the direction downstream of these recesses 111, 112 which are steplessly transitioned to subsequent areas of the protruding regions 109 or 110 of the supporting member 106.

In this embodiment, the positioning means 117, 118 are formed by actuators circulating in the direction of movement 108, in particular belt drives 120, 121, wherein the circulating actuators have at least the corresponding positioning means in the home position. Is moved to move continuously from the operating position to the operating position. In this way, in accordance with the moving direction and the moving speed of the web piece 102, processing of the edge areas 101 and 101a is performed to achieve accurate alignment of the edge areas 101 or 101a.

The deviation position of the edge regions 101 and 101a from the target position can be visually detected by the operator, allowing the operator to operate the corresponding device in a particular manner. However, it is also contemplated that the edge region 101, 101a or its outer edge is detected by suitable detectors on the sides of its position and the positioning means 117, 118 are operated in a particular manner by appropriate mechanical controls. Can and makes this possible.

The apparatus shown in FIGS. 7-11 is suitable for enabling the method of aligning the web piece 102, in particular the edge regions 101, 101a of the fabric piece, and is intended to be executed. The web piece 102 near the edge regions 101, 101a is conveyed by the conveyor, for example the conveyor 105, in this direction of movement 108 parallel to the edge region for this purpose. The web pieces are pressed by the driven conveyor 105 of the conveyor 103 against the support member 106 of the conveyor 103 and transported along the support member 106 in the direction of movement. As can be readily appreciated, the described device and procedure are provided on both sides of the web piece 102 so that the corresponding devices can be positioned and installed in both edge regions. The web piece can freely hang down between the parts of the device on either side, for example by forming a loop.

As specified, the support member 106 protrudes above the conveyor 105 at both sides in the transverse direction with respect to the direction of movement 108. The recesses 111, 112 located below the corresponding area of the web piece 102 are provided in the two protruding areas 109, 110. If the alignment of the web piece 102 deviates from the exact target alignment of the web piece 102, that is, its edge region 101 or 101a extends closer to the conveyor 105, the inaccuracy of the web piece 102 is incorrect. Aligned portions or edge regions 101, 101a are recessed adjacent the conveyor 105 and over the edge of the support member 106 traveling parallel to the direction of movement 108 or parallel to the direction of movement 108. Pulled out of the conveyor 105 by an appropriate amount in the direction transverse to the direction of movement 108 and transverse to the conveyor 105 by being pulled over the edge regions of 111 and 112, thereby causing deviation of the web piece 102. Correct to correct target alignment.

The traction force acting on the strip of material in the vicinity of the corresponding positioning means 117 and 118 is applied by the vertical force to achieve good force transmission and alignment. While the tension is applied, the means for applying the tension is preferably distorted in the web piece by applying a kinetic component to the strip of material that is moved parallel to or parallel to the direction of travel 108 of the conveyor 105. To prevent. The movement of the means parallel to the direction of movement 108 or the component of motion is adapted to the speed of the conveyor 105 in order to achieve a trouble-free action on the strip of material, in particular to avoid puckering. To facilitate alignment, the web piece 102 has visually recognizable edges or outer edges or marks, lines or steps that run parallel to the direction of travel so that alignments deviating from the target alignment perform or monitor the alignment method. It is recognized that the means deviate from the alignment, and the web piece is precisely aligned with the target alignment by the operation of the technical means. The monitoring means may be the naked eye of the operator or may also be electrical, electronic or other detection means.

The use of certain devices and specific methods provides an excellent way to properly align the edge regions of the flexible web piece according to the intended purpose so that subsequent operations such as the formation of the heme and the stitching of the heme can be followed mechanically. In particular, the alignment is performed during normal operation of the conveyor 103 so that accurate alignment can be performed during normal movement. The invention is not limited to the embodiment, but rather can be modified in many respects within the scope of the disclosure.
