The recess is formed as a window, letter or number. Grooves, notches and/or rebates are formed in the box blank, and inner contours are cut in the box blank. A stamping station (22) and a cutting station (23) are arranged in a running direction of the box blank for punching-out the recess and for cutting the contour, respectively. An independent claim is also included for a device for manufacturing folding box blanks from material sheet.

Description

The invention relates to a method for producing folding box blanks from a material sheet according to claim 1.

The invention also relates to a device for producing a folding box blank from a material sheet according to claim 8.

In the paperboard industry, it is the state of the art that folding carton blanks made of flat sheets of material are usually made of cardboard. Depending on the size of the folding carton blank, a plurality of folding carton blanks is produced from each material sheet. For this purpose, it is customary for the device for producing the folding box blanks to have two work stations which pass through the material sheets. The material sheet is placed in the first workstation on a die, which is preferably glued on a steel plate, placed. The matrix is decisive for the shaping of the folding box blank.

The matrix is usually made of plastic and has channels. To form creasing lines, the material sheet consisting of cardboard is pressed into the channels.

For producing the outer contour of the folding box blank and also for producing the inner contour, in particular for producing openings, Windows and motifs, cutting blades are lowered with high pressure on the material sheet. The cutting blades press in such a way on the sheet of material resting on the steel plate, that the material sheet is cut, but with connecting webs or connecting tongues remain, so that the Faltschachtelzuschnitt and the cut waste are still connected. This is necessary because otherwise the cut wastes would remain on the steel plate or the die during a further transport of the material sheet and thus a subsequent refilling of a new material sheet is hindered. It is essential, in particular because of the high operating speed, that the work process works quickly, simply and as trouble-free as possible. The punching method described is generally referred to as flat-bed punching.

In the second workstation, the connecting webs or connecting tongues are broken with the aid of pins, so that the cut waste is separated from the folding box blanks. In the second workstation, the cut wastes, after the connecting webs or connecting tongues were broken, usually omitted downwards. The material sheet with the folding box blanks, which is now freed at least from most pieces of waste, is transported further, stacked and subjected to the known further steps for producing a carton.

From the DE 1 134 880 is a punch for molding folding carton blanks known. The band steel cuts are in two parts, divided into the upper part and lower part formed. The upper part of the band steel tool carries the actual creasing and punching punches. It is envisaged that a band steel will outline the outlines of the blank, the flaps, the Locking tongues and the slots cut while another band steel forms folds or cuts along which parts of the blank are folded.

From the DE 2 253 154 and the DE 2 250 252 are known devices for breaking the punching waste.

From the DE 2 218 259 is the production of slip-lid boxes known, which is done by punching several blanks in the sheet, breaking the individual blanks, folding, straightening and stapling or gluing the tabs.

The DE 1 017 456 describes a blank for folding boxes made of paper, cardboard or the like. It is stated that connecting tongues arise during punching of the sheet where the cutting edges of the cutting tools are notched and as a result the sheet is not completely cut through. It is also mentioned that in a subsequent operation, the waste is "picked".

From the DE 190 378 and the DE 1 435 291 are known devices for punching paper and cardboard.

From the DE 10 2004 058 597 A1 a device for processing strip-like substrates is known, in particular of printed paper, cardboard, cardboard packaging, corrugated cardboard and plastics. Provided here is a rotation process in which the substrate in the feed direction between two rotating processing rollers can be inserted and when passing through effective in the cycle tool parts its Processing experiences. The waste pieces are disposed of in a controlled manner by means of known puncturing needles.

The known methods enable a fast, reliable and reliable machining of material sheets to produce folding carton blanks.

A disadvantage of the known methods, however, is that the connecting webs or connecting tongues, which are usually broken by pins, puncturing needles or the like, remain recognizable on the later product in the form of small projecting peaks or unevenness. However, this is especially for high-quality products that may have, for example, a window so that consumers see the product received in the carton directly, a significant disadvantage and disturbs the appearance.

Furthermore, there is the problem that filigree recesses, such as letters or delicate motifs, can not be produced because the puncturing needles, which are to break the connecting webs or the connection tabs and this must penetrate into the recess, can not be arbitrarily small dimensions.

From the general state of the art experiments are known to produce filigree recesses through the use of lasers. However, this causes the cut edges to discolor undesirably.

The present invention is therefore based on the object to provide a method and an apparatus for producing Faltschachtelzuschnitten, which solve the disadvantages of the prior art.

The inventive method for producing Faltschachtelzuschnitten from a sheet of material provides that in a first step, at least one recess, without leaving connecting webs, is completely punched out of the proposed Faltschachtelzuschnitt. This is preferably achieved in that a stamping punch completely punches through the recess and at the same time ejects the scrap piece or the cutting waste. Preferably, the punching is done with a so-called paper cut or the recess is sheared off. For this purpose, it can be provided that a plate, preferably a steel plate, on which the material sheet rests, has an opening, a recess or a hole with a shape which serves as a die for the recess to be created in the folding box blank. To punch through the recess, a punch or a stamp is preferably brought from above. The punch or the stamp moves into the opening, the recess or the hole in the plate on which the material sheet rests, and thereby cuts the material sheet. In this case, the punch or the punch simultaneously pushes through the further retraction into the recess, the opening or the hole of the plate, the cut piece of waste material sheet preferably down.

The principle of the invention preferably provides that is punched in a single operation and at the same time the punched piece of waste is ejected with.

It can be generated in this way at the same time or successively several recesses in the Faltschachtelzuschnitt.

The recess has no connecting webs or connecting tongues and thus also no notches and no stopping points. The edge or the edge of the recess is completely smooth when correctly performing the method or has no unevenness, so that a particularly high-quality Faltschachtelzuschnitt is created. The recess may serve, for example, as a window, so that a product to be introduced into the folding box is directly viewed by the consumer, without that breakpoints or notches of the encircling edge being visible in the window.

The inventively provided first method step also makes it possible filigree openings, for example, windows, letters, numbers, symbols or motifs to produce, which can be made almost arbitrarily small. So far, the recesses must not fall below a defined size or the shape was not allowed to be particularly delicate, since the puncture needles usually have a minimum size of 3 mm and this, so that the piece of waste can be ejected correctly, must penetrate into the recess. The puncture needles must emulate the course of the recess, so that a correct ejection can be ensured. These restrictions of the recess in terms of size and shape is no longer due to the method according to the invention.

In a second method step of the method according to the invention, it is provided to cut out at least one outer contour of the folding box blank from the material sheet while retaining connecting webs. The outer contour may include, for example, locking tongues or flaps.

In the second method step, further cuts can also be carried out in accordance with the known method of flat-bed punching or rotary blanking in order, for example, to cut inner contours. The known flat-bed punching method has basically proven itself for the production of folding box blanks. The flat bed punching is particularly advantageous if the connecting webs or the connecting tongues or their remnants, if the connecting webs or the connecting tongues are broken in a third method step, do not interfere with the finished carton. In particular, for the outer contour or the cutting of an inner contour can, if the connecting webs do not interfere, continue to fall back on the known method. Furthermore, in the second process step, for example, grooves and / or depressions and / or indentations and / or folds can be embossed into the folding box. The creases can represent kinking and bending known to form the carton blank to a carton.

The second process step may preferably be carried out as a flat-bed punching, but a rotary-stamping process using at least two processing rolls is also possible.

Preferably, it is provided in the second method step that a die, preferably a steel plate, a die placed, preferably glued, which dictates the shape of the carton blanks or the. On the plate with the die then the material sheet is applied. The matrix has channels or deep channels. By means of a corresponding tool, a part of the material sheet covering the channels can be pressed into the channels, whereby, for example, creasing lines are created.

In order to cut the outer contour of the carton blank from the sheet of material and optionally cut out an inner contour, each with retention of connecting webs, is preferably provided to press the cutting blade on the plate on the plate, preferably the steel plate, resting material sheet, as long as or with a such pressure until the material sheet is cut while retaining connecting webs. The purpose of the connecting webs is to hold together the material sheet, consisting of the folding box blanks and the cut waste, so that the material sheet can be transported further. The retention of connecting webs can be achieved for example by notches in the cutting blades.

In principle, it is advantageous in the second method step to produce not only the outer contour of the folding box blank, but also all further contours and also the score lines, insofar as these are necessary or desired.

According to the invention, it is provided that in the third method step, the connecting webs are broken. At the same time, the cut waste or at least part of the cut waste can be ejected. It is not absolutely necessary that all pieces of waste be ejected, if appropriate, these may also remain in the composite sheet, if this is desirable for stability, in particular with regard to onward transport.

The breakout of the connecting webs in the third process step is usually carried out in that puncture needles eject the cut waste or break the connecting webs. This can preferably take place in that the material sheet is placed on a base which is preferably open at the points at which the waste piece is to be ejected downwards. Preferably, puncture needles are then supplied from above, which push away or eject the cut waste downward by a corresponding pressure and / or by breaking or shearing off the connecting webs. The breaking out of the connecting webs and the ejection of the waste pieces can be achieved reliably. However, it can not be avoided that small notches, projections or holding points remain at the locations where the connecting webs were previously formed. Nevertheless, the method is advantageous for producing a folding carton blank quickly, easily and reliably. In most places, especially the outer contour of the carton blank is the whereabouts of small notches or breakpoints also not visually disturbing. In addition, the application of puncture needles in the outer contour is usually not problematic. This is problematic, however, if the recess is particularly delicate, since the point needles have a minimum size of 3 mm and thus require a correspondingly large space in the recess.

According to the invention, it can be provided that the first and the third method step are carried out in the same workstation of a device for producing folding box blanks.

The implementation of the first and the third method step in the same workstation has the advantage that the costs for implementing the first method step are low. In the workstation, in which the third process step has been carried out so far, can be simply integrate the first process step, since it is provided in the third step, ejecting cut waste. Instead of that, as in the third method step, now puncture needles or the like eject the cut waste, a recess is completely punched through in the first process step by means of a punch or a punch and preferably preferably ejected downwards at the end of the punching process.

The fact that the first and the third method step are carried out at the same workstation, eliminates the effort to create an additional workstation for performing the first method step. The inventive method can be carried out with simple modifications to known devices for the production of Faltschachtelzuschnitten.

It is advantageous if a two workstations having apparatus for producing Faltschachtelzuschnitten is used to carry out the method steps, wherein in the direction of flow of the material sheet first a workstation is reached, which is adapted to carry out the second process step and in the direction of passage thereafter a combined workstation is arranged which is suitable for carrying out the first and the third method step.

Two workstation devices suitable for performing the second and third process steps have been found to be particularly suitable for realizing a flat bed stamping process. Such devices can be modified particularly easily in order to additionally carry out the first method step according to the invention.

It is advantageous if the material sheet transported by the first loading into the device to the combined workstation and there the first process step is carried out, after which the material sheet is ejected and then fed to the device a further time, after which in the workstation, in the direction of passage is reached first, the second process step is carried out and the material sheet is then transported to the combined workstation to perform there the third process step.

This inventive control and the inventive implementation of the method steps on the device described have been found to be particularly suitable. Known devices can thus be converted and modified so that the method according to the invention can be carried out thereon.

Alternatively, it is of course also possible to carry out the first method step in a separate workstation, wherein the workstation is preferably arranged in the direction of passage in front of the workstation, which executes the second method step.

The inventors have recognized in a non-obvious way that it is particularly advantageous if the first method step, namely the complete punching of a recess, without connecting webs remaining, is performed as a first method step. In principle, it would also be possible to carry out the second method step first. It would even be preferable to run-off and even more obvious to carry out the complete punching without leaving connecting webs together with the method step in which the connecting webs pierced or broken out. The inventors have recognized here, however, that this is a significant disadvantage, as this undesirable deformations occur because the structure of the sheet of material is greatly affected by the previously made cutting the outer contour. The material sheet is, if the second process step is performed before the first, so weakened in its structure that the complete punching is made difficult according to the first process step.

It is advantageous if initially a stack of material sheets is processed one after the other according to the first method step and stacked again after ejection, after which this stack is then fed once more to the apparatus for executing the second and third method steps. To increase the utilization of existing machines, this process has been found to be particularly suitable.

Further insertion into the device can be dispensed with if two devices connected in line, each with two workstations, are used or if each method step is carried out on an independent workstation.

The device according to the invention for producing folding carton blanks from a material sheet provides a stamping station which is set up to punch out at least one cutout completely without leaving connecting webs from the folding carton blank provided. Furthermore, a cutting station is provided, which is set up to at least one outer contour of the folding box blank from the material sheet, while maintaining Connecting webs, cut out. Furthermore, a breaking-out station is provided, which is set up to break through the connecting webs and preferably eject at least part of the cut-off waste.

It is advantageous if in the stamping station the first method step already described according to the invention is carried out. Furthermore, it is advantageous if a known flat-bed punching or a rotary punching is carried out in the cutting station, preferably in the manner already described with regard to the second method step.

Furthermore, it is advantageous if the third method step, which has also already been described, is carried out in the breakout station.

It is advantageous if the punching station and the breaking station are combined to form a combined workstation. The resulting benefits have already been presented.

In a structural embodiment of the device can be provided that in the direction of passage of the sheet of material first the cutting station and then the combined workstation is arranged. This results in a particularly compact design. The other advantages have already been presented.

It is advantageous if the material sheet passes through the device twice, wherein in the first pass through the combined work station the at least one recess, without leaving connection webs, can be punched out of the folding carton blank provided, wherein in the second pass first processing by the cutting station and then a processing by the combined workstation to break the remaining after processing by the cutting station connecting webs and eject at least a portion of the cut waste.

The method according to the invention can thus be carried out on a modified, known and reliable device. Preferably, in a first pass in the first station, in this case the cutting station, not worked. In the second station, that is in the present case in the combined workstation, the punching out of windows or filigree motifs or the like takes place without connecting webs remaining. In the second station, in this case the combined workstation, the breakout usually occurs. Subsequently, the processed material sheet can be placed on a stack. After the stack has reached the desired size, it can be re-inserted into the device. Now takes place in the first station, that is, the cutting station, a processing, namely at least the cutting out of the outer contour while maintaining connecting webs. Furthermore, the grooves and / or depressions and / or indentations and / or folds can be embossed. Subsequently, in the subsequent second station, that is, the combined workstation, as usual, the breaking of the connecting webs and the ejection of the cut waste. Subsequently, the material sheets can be put back on a stack.

According to the invention it may be advantageous that the connecting webs are adapted in their design or in their strength that the material sheet in its stability by the already punched through recesses, especially possible windows or filigree motifs, is impaired. The connecting webs can therefore preferably be made stronger than is usual in the prior art.

The sheet of material may preferably be made of cardboard, paper, cardboard packaging, corrugated cardboard, plastic or similar substrates.

The material sheet can preferably accommodate a plurality of folding box blanks or a plurality of folding box blanks can be produced from a sheet of material.

A folding box blank produced by the method according to the invention or on the apparatus according to the invention has the advantage that recesses, in particular windows, letters, numbers, symbols and motifs, can be formed which have no residues of connecting webs, such as notches and holding points that a particularly advantageous appearance is created. Furthermore, very filigree recesses can be produced.

An exemplary embodiment of the invention is shown in principle below with reference to the drawing.

A method for producing folding box blanks, in particular a flat bed stamping method and a rotary stamping method, are well known from the general state of the art, for which reason only the features essential to the invention will be discussed in more detail below. In the manufacture of carton blanks, it is also known that they are made from a sheet of material, with typically each sheet of material cutting several rows of carton blanks includes and in each row a plurality Faltschachtelzuschnitte can be placed side by side or otherwise. From a sheet of material thus several carton blanks can be produced simultaneously. The exact number depends on the size or the structure of the later folding box and is for the solution according to the present invention not relevant.

It is also known that the material sheets can already be processed before carrying out the method steps according to the invention, in particular with a corresponding pressure. After carrying out the method steps according to the invention, further method steps may follow, in particular the assembly of the folding box. This will not be discussed further below.

The FIGS. 1 a and 1 b show a sheet of material 1, from the one in the FIGS. 4 and 5 Faltschachtelzuschnitt 2 or more folding carton blanks 2 can be produced example closer detail. The FIGS. 1 a and 1b show a first method step, in which a recess 3 is completely punched out of the folding box blank 2 provided, in such a way that no connecting webs remain.

In the exemplary embodiment, the recess 3 is punched out of the folding box blank 2 by means of a punch 4. For this purpose, a sheet of material 1 is placed on a base, for example a plate 5, preferably a steel plate or the like. The steel plate 5 has at least one hole, an opening or a recess, which are referred to below as a hole 6 for simplicity. The hole 6 has a shape corresponding to the later form of the Recess 3 in the folding box blank 2 corresponds or pretends. The punch 4 moves, as in Fig. 1 a is shown, preferably from above - the direction of movement is not relevant - down on the material sheet 1 and penetrates into the hole 6 of the steel plate 5 a. In this case, the punch 4 cuts, preferably by a shearing movement, the recess 3 from the folding box blank 2 from. A cut waste 7 of the recess falls, as in Fig. 1b is shown, preferably down from. Subsequently, the punch 4 is withdrawn again. It remains in the material sheet 1, a recess 3, which has no connecting webs, notches, breakpoints or the like. The peripheral edge of the recess 3 has no impairment.

In practice, since the material sheet 1 is typically suitable for producing a larger number of folding box blanks 2, several punch punches 4 simultaneously process the material sheet 1. It can also be provided that a folding box blank 2 has more than one recess 3, which are produced without connecting webs.

The recesses 3 can be used as windows, such as in Fig. 4 represented, but also as letters, as in Fig. 5 represented, or as numbers, symbols or motifs, in particular as filigree elements, are formed.

In a second process step, which in Fig. 2 is shown, preferably by a flat bed stamping, but also by a rotary punching, at least one outer contour 8 of the folding box blank 2 from the material sheet 1 while maintaining connecting webs. 9 be cut out. This is preferably done by, as in Fig. 2 represented, the sheet of material 1 on a pad 10, preferably in turn a plate, in particular a steel plate, is placed. There is a die 11, which has channels 12 between the steel plate 10 and the sheet of material 1. Preferably, from above a punching device 13 is lowered, which has cutting blades 14. The cutting blade 14 can be designed differently. The cutting blades 14 can serve, on the one hand, to cut out the outer contour 8 of the folding box blank 2 by pressing the punching device 13 against the steel plate 10 in such a way that the contour of the folding box blank 2 is cut from the material sheet 1 while retaining connecting webs 9. The cutting blades 14 may be notches and / or spaced from each other to form the connecting webs 9. This is known. On the other hand, the cutting knives 14 may also be designed so that they penetrate into the channels 12 to produce score lines 16 and / or depressions and / or notches and / or folds in the folding box blank 2. This method belongs to the prior art. It can be optional, such as in Fig. 4 also be provided that inner contours 15 are cut while maintaining connecting webs 9.

Fig. 3 shows the third process step, which is carried out after the second process step. The remaining after the second process step connecting webs 9 are broken out in the third process step. For this purpose, pins or puncturing needles 17 are provided. The material sheet 1 is preferably again on a pad 18, which may be a plate, preferably a steel plate act. The pad 18 preferably has a larger number from breakthroughs, so that the cut waste ejected by the puncturing needles 17 easily, preferably down - the direction plays here again, however, no matter - can be ejected. In Fig. 3 are shown counter-holders 19, which, in order to achieve a good breaking of the connecting webs 9, with the puncturing needles 17 may possibly cooperate. The method for breaking the connecting webs 9 is already known in principle, which is why at this point will not be discussed further.

Fig. 4 Shown is also the outer contour 8 and exemplarily some connecting webs 9 and creasing lines 16. Also shown is an inner contour 15. Manufacture can also be made perforations, folds, notches and indentations.

Fig. 5 shows of a Faltschachtelzuschnitt 2 only one produced after the first process step recess 3. Further details of Faltschachtelzuschnitt 2 are not shown here. In order to produce a recess 3, for example in the form of the letter "E", it is provided that the in Fig. 1 shown punches 4, if this is not viewed from the side, but viewed from below, the shape of an "E" has. Furthermore, in the FIGS. 1 a and 1 b illustrated steel plate 5, when viewed in a plan view from above, a hole 6 in the form of an "E", as in Fig. 5 is shown on. This makes it possible for the punch 4 to penetrate into the hole 6 and thereby the folding box blank 2 with the provided and in Fig. 5 shown recess 3 provides.

Fig. 6 shows in principle a possible structure of a device for carrying out the method steps 1 to 3. The arrow A symbolizes the passage direction.

It is of advantage if a larger stack 21 of material sheets 1 is first supplied to the first workstation, which in the exemplary embodiment is a punching station 22. The punching station 22 is set up to completely punch out a recess 3, as already described, without connecting webs 9, from the folding box blank 2 provided. The method can be carried out in such a way as already described with regard to FIGS. 1 a and 1 b has been described. Subsequently, the just-processed material sheet 1 of the second workstation, which in the present case is a cutting station 23, fed. From the stack 21 of the punching station 22, a new material sheet 1 can be fed simultaneously. The material sheet 1 now located in the cutting station 23 is at least worked so far that the outer contour 8 of the folding box blank 2 is cut out of the material sheet 1 while retaining connecting webs 9. As already regards Fig. 2 Creasing lines 16 and optionally an inner contour 15 as well as indentations, indentations or folds can also be produced. After completion of the processing, the material sheet 1 of a third workstation, in this case a Ausbrechstation 24 is supplied. At the same time, the material sheet 1 can be supplied from the punching station 22 of the cutting station 23 and a new material sheet 1 from the stack 21 of the punching station 22. In the breaking station 24, the method step 3, as this according to Fig. 3 was presented performed. The connecting webs 9 are broken and the cut wastes 7 ejected if necessary and to the extent desired. Subsequently, the material sheet 1 is transported further, wherein preferably a stack 25 is formed from a larger number of sheets of material 1.

Fig. 7 shows a modification of in Fig. 6 shown apparatus for producing Faltschachtelzuschnitten 2 from a sheet of material 1. It is provided that the in Fig. 6 shown first and third workstation, namely the punching station 22 and the breaking station 24, on which the first and the third method step are performed, combined to form a combined workstation 22/24. According to Fig. 7 It is envisaged that each sheet of material 1, the in Fig. 7 passes through the device shown twice. In the direction of passage of the material sheet 1, the material sheet 1 first reaches a workstation which is suitable for carrying out the second method step, as described in US Pat Fig. 2 is shown. This is the cutting out station 23. In the direction of passage thereafter follows the combined workstation 22/24, which is suitable for the first and the third method step, as described in US Pat Fig. 1 and Fig. 3 is shown execute.

After inserting a sheet of material 1, preferably from a stack 21 of sheets of material 1, this is transported through in the device to the combined workstation 22/24. In the Ausschneidestation 23 initially no processing takes place. In the combined workstation 22/24, as already described, the first method step is then carried out. The steel plate 5 and 18, on which the sheet of material 1 rests, is suitably designed accordingly.

Subsequently, the material sheet 1 is ejected and preferably stacked on a stack 26, as long as a suitably large Stack of sheets of material 1 has come together. The stack 26 with material sheets 1 is then, as in Fig. 7 shown in dashed lines, the device supplied again. The material sheets 1 thus pass through the device a second time. In this second pass, processing takes place in the cutting out station 23 according to the second method step, which is described, for example, in US Pat Fig. 2 was presented. Subsequently, the material sheet 1 is further transported to the combined workstation 22/24 to perform there the third process step.
