EP3301218A2 - Method and device for feeding laundry items into a laundry treatment device, in particular a mangle - Google Patents

Abstract

The feeding of laundry items to, for example, mangles done with input machines. These have a spreading device (12) with movable expansion clamps (14), which spread a front transverse edge of the garment in front of a feed conveyor (17) and centered center. Before the spreader (12) are usually several loading stations (11). So far, the Spreizklammern (14) get the respective laundry from the loading stations (11). This requires at outer loading stations (11) long travels of the Spreizklammern (14), which reduces the cycle time of the input machine. The invention proposes to transfer laundry items from external loading stations (11) to transfer clamps (21), which move the laundry items from the external loading stations (11) to the vicinity of the center of the feed conveyor (17) in order to place the respective laundry item in the middle of the feed conveyor (17) to the Spreizklammern (14) to pass. This reduces the travel paths of the expansion clamps (14).

Description

The invention relates to methods for feeding items of laundry to a laundry treatment device, preferably a lack, according to the preamble of claim 1, 13 and 17. The invention further relates to devices for feeding laundry items to a laundry treatment device, preferably a defect, according to the preamble of Claim 5, 9, 11, 15 and 19, respectively.

Laundry items are supplied to laundry treatment equipment such as mangles with devices commonly referred to as input machines. In this case, transverse edges, which are also referred to below as the front edge or the rear edge, run transversely to the feed direction.

It is known to spread the items of laundry of a spreading and lay down in the expanded state of the spreading on a feed conveyor or an associated Ablegeleiste. The spreading device has spreading clamps which can be moved transversely to the feed direction and which hold adjacent corners of a transverse edge, in particular a front transverse edge, and extend or spread this transverse edge by moving apart. The laundry is still spread by the Spreizeinrichtgung.

It is also known to hang the laundry items at a plurality of juxtaposed loading stations with a lying between the adjacent corners portion of its transverse edge. The laundry items are then transported by each loading station in the feed direction of the input machine and transferred from transfer brackets, the corners of the Spreizklammern.

A disadvantage of the known input machines is a relatively large travel of the Spreizklammern of external loading stations. It is also disadvantageous in known input machines that the items of laundry placed on the respective loading station with a central or near-center portion of each front transverse edge can slipping uncontrollably from lay-up areas of the loading stations. The same applies to the extended transverse edge region of the item of laundry laid down by the expansion clamps on a front region of the supply conveyor. Finally, the loading stations which are arranged in a stationary manner in front of the spreading device in the case of known input machines can have an ergonomically unfavorable effect on the application of areas of the items of laundry to their place of placement even when mangles are growing.

The invention has for its object to provide a method and apparatus for supplying laundry items to a laundry treatment device, in particular a defect, which ensure a high treatment performance and a reliable and ergonomic operation.

A method for achieving this object comprises the measures of claim 1. This method provides that laundry items are transferred from external loading stations with a reduced distance with respect to the outer loading stations to the center of the feed conveyor to the expansion clamps. This shortens the travel of the expansion clamps after the acquisition of the respective laundry item. This leads to shorter cycle times. In addition, the transfer of laundry items from a central loading station to the spreader is not hindered by the transfer of the laundry items with a reduced distance to the center of the feed conveyor.

It is preferably provided that items of laundry are transferred to the expansion clamps when the expansion clamps of a pair of expansion clamps have moved together. This allows a space-saving transfer of laundry items to the respective Spreizklammerpaar.

Furthermore, it is preferably provided that the Spreizklammern for accepting the respective item of laundry have a relation to the outer Beladestationen reduced distance to the center of the feed conveyor, said distance to the center of the feed conveyor corresponds to at least half the distance between the two expansion of a Spreizklammerpaars. At this half distance then the directed towards the center of the feed conveyor Spreizklammer the Spreizklammerpaars is removed from the center of the feed conveyor. As a result, expansion clips which take over laundry items from off-center loading stations do not disturb the transfer of items of laundry from a middle loading station.

An advantageous possibility for further development of the method provides that the respective item of laundry is transferred from a pair of spreading clamps driven on the center of the supply conveyor from a central loading station arranged between external loading stations. In spite of this offset, the expansion clamps of outboard loading stations do not interfere with the center of the feed conveyor because they are moved only so far to the center of the feed conveyor that there is still room for a central pair of spreader clamps for indirectly or directly receiving a respective item of laundry from a central loading station.

An advantageous development of the method provides that the items of laundry are transferred from or to the respective loading station to a movable transfer bracket pair that moves the laundry to the respective, in particular next, Spreizklammerpaar. At the end position of the pair of transfer staples, the respective item of laundry is then transferred to a pair of spreader clips. The respective pair of transfer staples can thus transfer the respective item of laundry from the off-center loading station to a pair of spreading clips which are provided near and / or next to the center of the supply conveyor. After a Spreizklammerpaar from Transferklammerpaar a piece of laundry near the center of the feed conveyor - but not in the middle of the feed conveyor - has taken over, the travels of the Spreizklammern for extending the front transverse edge and for centering the laundry item with extended transverse edge only relatively short. This reduces the cycle times.

A further possibility of the advantageous embodiment of the method is to move the transfer clamps outboard loading stations in end positions that are less far from the center of the feed conveyor than the relevant external loading station. Preferably, the distance is between the center of a transfer bracket pair to the center of the feed conveyor 1-1½ times the distance of the transfer staples of the transfer staple pair. Thereby, the transfer clamps can be moved as close as possible to the center of the feed conveyor, without hindering the loading of other expansion clamps with, for example, from the central loading station originating laundry items.

An apparatus for solving the above-mentioned problem has the features of claim 5. In this device, transfer clamps of outboard loading stations are movable on oblique rails toward the center of the feed conveyor, with the rails of the outboard loading station terminating at a distance adjacent the center of the feed conveyor. As a result, the outer transfer clamps for transferring laundry items to the expansion clamps can be moved close to the center of the feed conveyor. However, the transfer brackets of outboard loading stations are moved to the center of the infeed conveyor only so far that they do not hinder the transfer of such items of laundry originating from the central loading station.

Preferably, it is provided that the rails arranged downstream of the outer loading stations run obliquely in the direction of travel of the pairs of transfer brackets in the direction of the feed conveyor, preferably to the center of the same and / or inclinedly rising. The items of laundry are thereby not moved transversely to the feed direction by the pairs of transfer staples, but also in the feed direction to the spreading device spaced apart from the loading station and optionally or alternatively also lifted in order to be able to transfer areally larger items of laundry to the supply conveyor.

In an advantageous embodiment possibility of the device, it is provided to provide the outer loading stations associated rails with a certain length. This length is chosen so that the transfer bracket pairs of the outer loading stations associated rails for transfer of laundry items to the expansion brackets so far to the expansion brackets are so far that when passing the laundry items to the expansion brackets the centers of the transfer bracket pairs only to the 1- to 1½ -fold distance of the respective transfer bracket pair from the center of the feed conveyor are removed. This also allows the laundry load to be transferred from the central loading station to a central pair of spreader clips, regardless of items of laundry that originate from the outer loading stations.

An advantageous development of the device provides, seen in the feed direction to move the transfer bracket pairs in the final position in front of each pair of Spreizklammer and / or that behind each moved into the final position transfer bracket pair, the Spreizklammern are moved along. As a result, the expansion clamps can be arbitrarily moved on their transverse to the feed rails, over the entire length of the rail, even if at least one transfer pair has moved into the final position for transferring a piece of laundry to a Spreizklammerpaar.

Another device for achieving the object, which may also be a preferred development of the device described above, has the features of claim 9. Accordingly, each loading station has a narrow loading conveyor with at least one circulating conveyor belt guided between deflection drums and a support means carrying the deflection drums. In such a loading conveyor, it is provided to dimension the suspension element in cross section so that it is only marginally wider under the upper run of the conveyor belt than opposite edges of the upper run. As a result, the region of the item of laundry located in the region of the loading station essentially only supports itself on the upper run of the loading conveyor, but not or only insignificantly on the carrying means which are stationary with respect to the running conveyor belt. This leads to a better traction of resting on the conveyor belt portion of the laundry article. As a result, the laundry is taken more reliably by the circulating driven conveyor belt.

It is preferably provided that a deflection drum assigned in particular to a loading end of the respective loading conveyor, which optionally can also simultaneously serve as a drive drum, corresponds approximately to the width of the conveyor belt of the loading conveyor. The tail pulley can be as wide as the conveyor belt, but also slightly wider for tolerance reasons. As a result, opposite end faces of the deflection drum do not inhibit the traction of the part of the item of laundry resting on the upper run of the conveyor belt at the beginning of the loading conveyor. The laundry item is thus taken more reliably by the circulating driven conveyor belt in the feed direction, without the risk of slipping of resting on the upper strand of the loading conveyor part of the laundry item consists of the conveyor belt.

Another device for solving the above-mentioned object, which may also be a preferred development of the device described above, has the features of claim 11. This provides that each loading station one Has loading conveyor of two at least partially stacked belt conveyors. A lower belt conveyor is facing an upper belt conveyor forward to form a loading point or a loading area for each laundry item. The front part of the lower belt conveyor is adjustable. Preferably, the front part of the lower belt conveyor forming the layup area is pivotable and / or height adjustable. As a result of this adjustability, the laying area can be adjusted in height and alternatively or additionally also in the inclination for adaptation to a respective operator. This can adjust the lay-up area individually. This contributes to the improvement of the ergonomics of the device.

An advantageous embodiment possibility of the device provides that the respective loading point or the respective laying area forming and / or having front part of the lower belt conveyor is adjustable by pivoting relative to its rear part. The rear part then forms a pivot axis about which the front part with the front deflection drum of the lower belt conveyor is pivotable. The front part with the front deflecting drum of the lower belt conveyor is thereby variable in both the inclination and in height.

A preferred possibility for further development of the device provides for the front deflecting drum of the upper belt conveyor, set back relative to the front deflecting drum of the lower belt conveyor, to be designed as a guiding and / or tensioning drum of the upper run of the lower belt conveyor. This front tail pulley of the upper belt conveyor thus has a multiple function. It forms a kind of kinking of the upper run of the longer lower belt conveyor, when its laying area is swung up. In addition, while the front idler pulley of the upper belt conveyor tensioned by at the upper strand of the lower belt conveyor in the region of its pivot axis, the at least one conveyor belt of the lower belt conveyor. It is thus a particularly simple and effective adjustment of the height and / or inclination of the laying area of each loading station possible.

Another method for solving the above-mentioned object, which may also be preferred developments of the method described above, has the measures of claim 13. This method provides a front transverse edge region of the item of laundry with an oscillation angle of more than 95 ° onto the supply conveyor, in particular its front deflecting drum and / or the adjoining front region of the upper strand of preferably several adjacent narrow conveyor belts of the infeed conveyor with a wrap angle from over 95 °. As a result, the front transverse edge region of the item of laundry deposited on the supply conveyor receives a frictional engagement sufficient for reliable entrainment from the supply conveyor. Even larger items of laundry, which hang down with a large area after placing the front edge region on the beginning of the feed conveyor before the same, are coupled by the more than quarter-circular wrap of the front part of the feed conveyor reliably frictionally and / or non-positively thereto. The risk of slipping down even larger items of laundry and laundry items from relatively smooth materials from the front end of the feed conveyor is so reliably avoided.

It is preferably provided that the front transverse edge region of the respective item of laundry is spread out by the expansion clamps and centered on a front deflection region of preferably a plurality of narrow adjacent conveyor belts of the supply conveyor. This depositing preferably takes place in such a way that the item of laundry is deposited on the front deflection region of the supply conveyor such that the item of laundry rests against the deflection drum with a wrap angle of more than 95 °, preferably 100 ° to 140 °. In this way, the laundry item receives when passing on the front portion of the feed conveyor sufficient frictional and / or adhesion.

Another device for solving the above-mentioned object, which may also be a preferred embodiment of the device described above, has the features of claim 15. Here, the upper run of the at least one conveyor belt of the feed conveyor runs at least in a feed direction viewed in the front starting area on which the front transverse edge of the laundry is placed, viewed in the feed direction by at least 5 ° to the horizontal downwards inclined. As a result of the downwardly inclined starting region of the upper strand of the feed conveyor, the wrap angle of the narrow front transverse edge region of a respective item of laundry to be deposited on the same is increased, specifically over a quarter circle area.

Preferably, it is provided that the upper strand of the at least one conveyor belt of the feed conveyor extends inclined at least in the initial region over an angle of 10 ° to 15 ° to the horizontal in the feed direction. This leads to a particularly effective coupling of the front edge region to the feed conveyor, in particular in the region of the front deflection drum thereof, if this front edge region of the expansion clamps is placed on the feed conveyor. This eliminates the risk of slipping down of the front edge region of a piece of laundry from the feed conveyor, especially for larger laundry items.

Another method for the solution of the above-mentioned object, which may also be preferred developments of the method described above, comprises the measure of claim 17. This method can also be an advantageous development of the previously described methods. The method provides that if necessary, when an operator is to have free access to the front feed end of the feed conveyor, at least the or each loading station is extended. Preferably, the at least one loading station is swung up. Thus, it is possible for one or more operators, for the purpose of growing a feeder conveyor downstream lack of a so-called oilcloth manually hang up on the task end of the feed conveyor, without thereby disturbing the at least one loading station in front of the feed conveyor.

A preferred embodiment of the method provides, not only the at least one loading station, but also the spreader and possibly the or each pair of transfer staples hochzuschwenken with this associated Verfahrschiene together as a unit, so that the spreader and the at least one optionally provided transfer bracket pair with the associated Verfahrschiene not interfere with the manual laying of the so-called oilcloth on the Auflegeende of the feed conveyor. Conversely, after the completion of the growth of the lack together, the at least one loading station of the spreader and optionally the at least one pair of transfer staples with its rail swung back to its initial and operating position.

Another device for solving the above-mentioned object, which may also be a preferred development of the device described above, has the features of claim 19. Accordingly, it is provided to arrange the at least one loading station and / or the spreading device and / or the at least one transfer pair with the associated rail on a common pivoting device. This pivoting device allows a common pivoting of the at least one loading station, possibly also the spreader and / or the at least one transfer pair with the associated rail. The said components of the device can be used for free access to Auflegeende swung up the supply conveyor and then swung back into the operating position. As a result, in particular, the manual growth of a downstream of the feeder conveyor is made easier or only possible.

The figures show a device designed as an input machine. In the Fig. 1 to 5 this input machine is completely displayed. The input machine is used to supply items of laundry, not shown, and especially flat items such as sheets, duvet covers, pillowcases, towels, tablecloths and the like in the feed direction 10 to a defect not shown in the figures. The apparatus may also serve to supply laundry items to other laundry treatment equipment, for example, folding machines.

The device or input machine shown here has three identically formed loading stations 11. The three loading stations 11 are arranged at the same distance from each other in a direction transverse to the feed direction 10 row on the front of the input machine. The middle loading station 11 is located in the center of the input machine shown. The two other loading stations 11 are arranged on opposite sides of the central loading station 11 eccentrically with the same distance from the central loading station 11. The invention is also suitable for Input machines with a larger or smaller number of loading stations 11, even for input machines with only a single loading station 11.

When viewed in the feed direction 10, a spreading device 12 follows the loading stations 11. The spreading device 12 has a horizontal rail 13 extending transversely to the feed direction 10, on which carriages 15 carrying a spreading clamp 14 can be moved transversely to the feed direction 10. In the apparatus shown four preferably identically formed Spreizklammern 14, each with its own carriage 15 are provided. However, it is also conceivable that the spreading device 12 has only two or more than four expansion clamps 14. Each two Spreizklammern 14 with a mirror image arrangement to each other form a Spreizklammerpaar for adjacent corners of an advancing in the feed direction 10 transverse edge of the laundry article. The expansion clamps 14 of each pair can be moved together and moved apart transversely to the feed direction 10. In the contracted state take over the two expansion brackets 14 of a pair adjacent corners of the front transverse edge of a piece of laundry. By lateral movement and moving apart of the expansion clamps 14 of the respective Spreizklammerpaars the front transverse edge of the garment is spread or stretched to spread the garment under the spreader 12. In addition, the garment is centered by the Spreizklammern 14 of the respective Spreizklammerpaars relative to the center of the device or eingemittet ,

As seen in the feed direction 10, the spreader 12 is followed by a feed conveyor 17. The laundry item spread and fed in by the spreader 12 is transferred from the spreader clamps 14 of the spreader pair to a front end 16 of the feed conveyor 17 with the leading edge extended. This is done by centrally depositing a front, stretched transverse edge region of the laundry item on the located in the front end 16 of the feed conveyor 17 portion of an upper run of the feed conveyor 17. The middle of the laundry is thereby placed in the center of the feed conveyor 17. The center of the feed conveyor 17 is located in a feed direction 10 extending vertical longitudinal center plane of the input machine.

From the feed conveyor 17 is spread and / or stretched out on the same lying laundry to the defect not shown in the figures or other laundry treatment device transported.

The feed conveyor 17 extends from its front end 16 downwards inclined in the feed direction 10, ie in the direction of the laundry treatment device ( Fig. 5 to 7 ). As a result, the upper run 51 formed in the feed direction 10, which is formed by a plurality of closely spaced narrow circulating conveyor belts 52 at a small distance next to one another, also slopes downwards in the feed direction 10. According to the illustration in particular the Fig. 7 extends the upper run 51, starting from a tail pulley 53 at the front end 16 of the feed conveyor 17 at an angle 30 ° to the horizontal to a seen in the feed direction 10 subsequent rear, lower deflecting drum 54th

As a result of the obliquely downward course of at least the upper strand 51 of the feed conveyor 17 passes from one pair of Spreizklammerpaar the spreader 12 on the front end 16 of the front tail pulley 53 outgoing front end portion 16 of the upper strand 51 of the feed conveyor 17 launched laundry 40 with a front transverse edge region 42, below in the Fig. 7 drawn angle 43 of 120 ° with respect to the still before the front end 16 of the feed conveyor 17 in the extended state perpendicular drooping lagging part of the laundry piece 40. As a result, the transverse edge portion 42 of the laundry 40 is at an angle 43 corresponding wrap angle of 120 ° around the tail pulley 53 deflected portion of the adjacent conveyor belts 52 of the feed conveyor 17 at. This wrap angle of more than 90 ° leads to an improved frictional engagement between the conveyor belts 52 and the front transverse edge region 42 of the laundry article 40, whereby the risk of slipping down after placing the laundry article 40 on the front end 16 of the supply conveyor 17 only with the narrow front Transverse edge region 42 on the conveyor belts 52 resting laundry 40 is eliminated.

The feed conveyor 17 shown has a suction box 55 arranged below the upper run 51 between the deflection drums 53 and 54. On a provided with perforations 57 top wall 56 of the suction box 55 a front part of the upper run 51 of the feed conveyor 17 runs along. As a result of the air-permeable conveyor belts 52, the region of the item of laundry 40 lying behind the front deflecting drum 53 is firmly sucked onto the upper run 51 with slight negative pressure. This leads to an additional frictional and / or non-positive fixation of the laundry item 40, in particular its transverse edge region 42, on the upper run 51 of the feed conveyor 17. However, the invention is not limited to the additional sucking fixation of the laundry items 40 on the feed conveyor 17. Especially with larger front tail pulley 53, it may be sufficient alone if the front transverse edge region 42 of the laundry article 40 only over a wrap angle of about 120 ° in the region of the front deflecting drum 53 of the feed conveyor 17 is frictionally fixed.

The wrap angle 43 is not limited to the 120 ° shown. He can be bigger or smaller. At least the wrap angle should be 43 but 95 °. It can also be greater than 120 °, for example up to 140 °.

Each loading station 11 has a loading conveyor 18, which transports the laundry item in the feed direction 10, and two subsequent corner finders 19 for respectively adjacent corners or corner regions of a second, originally rear transverse edge of the laundry item.

In the illustrated device or input machine 12 transfer brackets 20 are provided between the two corner finders 19 each loading station 11 and the spreader 12. The two transfer clamps 20 each associated with a corner finder of each loading station 11 are combined to form a pair of transfer clamps 21. The transfer brackets 20 and the transfer bracket pair 21 thereby form a double clamp for one of the opposite corners of the transverse edge of the laundry item.

The pair of transfer staples 21 of each loading station 11 can be moved with a carriage on a rail 22, 23, 24. The rail 22 of the middle loading station 11 runs straight in the feed direction 10 along the center of the input machine and the feed conveyor 17. The rail 22 extends in the feed direction 10 upwards.

From the outer loading stations 11 go longer obliquely upward and in the direction of the spreading device 12 extending rails 23, 24. Both rails 23, 24 are of equal length but differently oriented so that their rear ends 25 seen in the feed direction 10 are converging towards the center of the input machine but terminate before the center. The ends 25 of the rails 23 and 24 are spaced from the end 26 of the central rail 22 by a little more than the width of a transfer bracket pair 21. The ends 25, 26 of the rails 22, 23 and 24 lie on a common horizontal (imaginary) Line extending parallel to the rails 13 of the spreader 12, but with distance in front of and / or above. The lengths of the rails 22, 23 and 24 and the positioning of their ends 25, 26 are made such that the expansion clamps 14 can pass the transfer clamps 20 in a collision-free manner, in the shown embodiment in the feed direction 10 behind the transfer clamps 20 (FIG. Fig. 11 ).

Each of the same trained loading conveyor 18 of the loading station 11 has two narrow, equal width belt conveyor 27, 28, each with at least one circulating conveyor belt. The belt conveyors 27, 28 are arranged one above the other to form a sandwich conveyor. The upper belt conveyor 27 is shorter than the lower belt conveyor 28, wherein the upper belt conveyor 27 as seen in the feed direction 10 is located behind the beginning of the lower belt conveyor 18 to form an exposed front portion of an upper run 39 of the lower belt conveyor 28, so a laying area 29 for a respective laundry 40 forms.

On the lay-up area 29 of the lower belt conveyor 28 for loading the input machine in the region of the respective loading station 11 a lying between adjacent corners of the front transverse edge of the laundry article 40, ideally central, narrow transverse edge portion is placed ( Fig. 13, 14th . 16 ).

The conveyor belt of the longer lower belt conveyor 28 is driven indirectly by entrainment from the conveyor belt of the driven shorter belt conveyor 27 or an intermediate between the conveyor belt of the driven shorter belt conveyor 27 is preferably driven only on the shorter upper belt conveyor 27, for example on a tail pulley the upper run 39 of the lower belt conveyor 28 and the lower run of the upper belt conveyor 27 lying part of a laundry 40th

The lower belt conveyor 28 is provided with a support means 38 for supporting its rotatable front deflection drum 47 and its rear deflection drum 41. The support means 38 is according to the invention insignificantly wider than the front or lower deflection drum 47 of the belt conveyor 28 is formed ( FIGS. 15 and 16 ). Preferably, the width of the support means 38 on outer, opposite side walls 37 is only 4% to 20%, preferably 5% to 12%, wider than the width of the front tail pulley 47. As a result, the approximately U-shaped nestles with an inner, preferably approximately Central, section of the front transverse edge region on the laying area 29 of the belt conveyor 28 launched laundry 40 tightly against the opposite end faces 36 of the lower deflection drum 47 at.

In addition, the side walls 37 of the support means 38 are provided only with a reduced height which is smaller than the distance of the strands of the lower belt conveyor 28, preferably near the bottom of the cylindrical lateral surface 34 at least the front deflection drum 47 is located ( FIGS. 15 and 16 ). Between the idler pulleys 41, 47 are opposite side walls 37 of the support means 38 formed even lower by being below a rotation axis 58 of the front deflection drum 47 ( FIGS. 15 and 16 ). In the illustrated embodiment, the upper longitudinal edges of the opposite side walls 37 of the support means 38 are approximately ¾ of the diameter of the tail pulley 47 under the formed by the upper run 39 laying area 29 of the lower belt conveyor 28. Thus coming from the laying area 29 on both sides drooping down longitudinal edge portions of the laundry 40 only on narrow lower portions of the side walls 37 of the support means 38 to the plant.

As a result of the narrow side walls 37 of the suspension element 38 of the belt conveyor 28, which are as close as possible and are reduced in height, the side walls 37 only exert very small support forces on the longitudinal or side wall regions of the laundry article 40 suspended on both sides from the laying region 29. This results between the garment 40 and the side walls 37 of the support means 38 only very low frictional forces, which hardly counteracts the frictional force of resting in the application area 29 on the upper run 39 of the belt conveyor 28 part of the laundry article 40 and thereby reduced only insignificantly. This leads to an effective frictional and / or non-positive coupling and entrainment of the laundry item 40 from the top run 39 of the belt conveyor 28 in the laying area 29. A risk of slipping down the front of the laundry item 40 from the laying area 29 before reaching the sphere of influence of the upper belt conveyor 27 is thereby avoided ,

Notwithstanding the illustrated embodiment, it is conceivable to allow the opposite side walls 37 of the support means 38 to run slightly obliquely in opposite directions, so that they easily converge to the lay-up area 29 of the lower belt conveyor 28. This leads to a further reduction of the frictional force between the opposing side wall portions of the laundry article 40 hanging down on both sides from the overlay region 29 and thereby to an even stronger frictional and / or non-positive coupling thereof to the upper strand 39 in the overlay region 29 of the belt conveyor 28.

Between the tail pulleys 41 and 47 upper and lower edges of the side walls 37 of the support means 38 are provided with preferably at right angles to the side walls 37 angled upper edge strips 49 and lower edge strips 50. The edge strips 49 and 50 are angled inwardly between the side walls 37 and each have a width which is less than half the distance of the side walls 37, so that between the mutually facing free ends of the edge strips 49 and 50 remains a central space. Between the edge strips 49 and 50 a largely lying under the deflection drums 41 and 47 chamber is formed, which serves to receive an empty returning strand 48 of the circulating, endless conveyor belt of the lower belt conveyor 28. In this chamber, the lower run 48 of the conveyor belt can travel undisturbed by the side wall regions of the laundry article 40 which hang down on opposite sides of the lower belt conveyor 28 ( FIGS. 15 and 16 ).

The Fig. 15 and 17 illustrate further that the width of the circulating conveyor belt of the lower belt conveyor 28 corresponds to the width of at least the front tail pulley 47 or optionally slightly narrower.

According to the invention, the laying area 29 of each loading conveyor 18 is adjustable. The FIGS. 17 to 18 on the one hand and the FIGS. 19 and 20 on the other hand show various adjustment positions of the laying area 29 of a loading conveyor 18. In the same way, the laying areas 29 of other loading conveyor 18 are adjustable.

The adjustment of the lay-up area 29 of the respective loading conveyor 18 takes place in the embodiment shown here by a change in height of the front deflection pulley 29 located at the beginning of the lay-up area 29 of the lower belt conveyor 28 of the loading conveyor 18.

A lower run 48 of the circulating conveyor belt of the lower belt conveyor 28 is assigned a preferably freely rotatable deflection roller 45. The guide roller 45 is positioned above the lower run 48, approximately midway between the guide drums 41 and 47 of the belt conveyor 28. As a result, the guide roller 45 is pressed from above against the Untertrum 48 when moving up the front guide pulley 47, making this an increasing V-shaped Configuration receives.

Preferably, the deflection drum 47 is pivotable on a circular path with a circle center on the guide roller 45. The deflection drum 47 and the deflection roller 45 are mounted for this purpose on a common support member, preferably with two parallel pivot arms (not shown in the figures) connected. The longitudinal central axis and axis of rotation of the deflection roller 45 serves as a pivot axis for the pivot arms.

The upper run 39 of the conveyor belt of the lower belt conveyor 28 is assigned to the end of the lay-up area 29, ie between the deflection drums 41 and 47 of the lower belt conveyor 28, a front deflecting drum 46 of the upper belt conveyor 27. Because this is above the lower belt conveyor 28, pushes the tail pulley 46 of the upper belt conveyor 27 on the upper strand 39 of the lower belt conveyor 28. When in the Fig. 17 to 20 The loading conveyor 18 shown, the front idler pulley 46 of the upper belt conveyor 27 is approximately over the guide roller 45 on the lower run 48 of the lower belt conveyor 28. The front guide pulley 46 of the upper belt conveyor 27 may also lie in front of and behind the guide roller 45.

As a result of the above-described assignment of the front deflecting drum 46 of the upper belt conveyor 27 to the upper run 39 of the lower belt conveyor 28, the deflecting drum 46 at the same time serves to guide the upper run 39 of the conveyor belt of the lower belt conveyor 28 during the mounting of the laying area 29 of the loading conveyor 18. and moving the front deflecting drum 47 of the belt conveyor 28 to tension (cf. Fig. 18 and 20 ).

As a result of the above-described adjustability of the loading conveyor 18, the initial areas of the laying areas 29 of the loading conveyor 18 defined by the front deflection drums 47 of the lower belt conveyors 28 are height-adjustable independently of one another. In addition, thereby the inclination of the respective lay-up area 29 is variable. When pivoting the respective deflection drum 47, the inclination of the respective laying region 29 is reduced by the lay-up region 29, as seen in the feed direction 10, rising less sharply (FIG. FIGS. 17 and 18 ) as in downwardly pivoted and reduced in height front tail pulley 47 ( FIGS. 19 and 20 ).

The corner finder 19 of the respective loading station 11 are seen in the feed direction 10 associated with a rear end 30 of the lower belt conveyor 28, on both sides adjacent to the rear end 30 of the belt conveyor 28 and partly behind it. Each of the preferably identically formed, but by arrangement on opposite sides of the end 30 of the belt conveyor 28 mirror image oriented corner finder 19 has two rollers 31, 32, which together form a pair of rollers with parallel longitudinal central axes or axes of rotation. Between the rollers 31, 32 of the roller pair, a nip 33 is formed.

A roller 31 of each corner finder 19 is rotationally driven. These independently driven separately rollers 31 on both sides of the tail pulley 41 at the rear end 30 of the belt conveyor 28 lie on a common line transverse to the feed direction 10. On this line are the axes of rotation of the driven rollers 31 and the tail pulley 41 of the belt conveyor 28th

The driven rollers 31 are the same as the tail pulley at the end 30 of the belt conveyor 28 arranged stationary. By contrast, the rollers 32 are movably mounted on a pendulum arm.

With some distance behind the beginning of the upper belt conveyor 27 each loading conveyor 18 is surrounded by a guide channel, which is formed in the embodiment shown as a top largely open U-shaped groove 35. Through the channel 35 opposite side or longitudinal edges of the laundry item are further pulled in the feed direction 10 between the belt conveyors 27 and 28 and guided guided to the behind behind the channel 35 on both sides next to the loading conveyor 18 arranged corner finders 19.

The end of the respective side edge region of the item of laundry in the area of the relevant corner finder 19 is detected by detection means, in each case at least one such detection means being provided outside each corner finder 19 on both sides of the belt conveyor 28. As a result of the independent detection means of each corner finder 19, an optionally consecutive passage of the end of the left and right side edges of the laundry article from, for example, sensor lines is detected independently. As soon as the passing of a rear end of a side edge region of the item of laundry at one or the other corner finder 19 is detected by the corresponding sensor line, the drive of the driven roller 31 of the respective corner finder 19 is stopped. Then, each corner finder 19 becomes a corner of an originally rear transverse edge fixed in the manner of a clip, in such a way that the outermost point of the relevant corner of the laundry item is just in the nip 33, but at least just before it.

As soon as the two independently operating corner finders 19 on opposite sides of the belt conveyor 28 have each detected and fixed one corner of the laundry item tightly at the outermost corner point, both transfer corners of the original two transfer clamps 20 of the transfer clamp pair 21 moved close to the corner finder 19 bottom transverse edge and now front transverse edge of the garment seized and pinched.

From the pair of transfer staples 21, the laundry item held thereon with opposite corner regions of a now forward transverse edge is transferred to two free adjacent expansion clips 14 of the spreader 12 forming a pair of spreader clips.

From the middle loading station 11, the pair of transfer staples 21 with the load at the middle loading station 11 laundry along the straight in the feed direction 10 extending rail 22 to the upper end 25 of the same process, especially obliquely raised. This end 25 is located in the vertical longitudinal center plane of the device or input machine. At the end 25 of the rail 22, the laundry item is transferred from the two transfer clamps 20 of the transfer bracket pair 21 to two driven to the center of the input machine expansion clamps 14 of Spreizklammerpaars with mutually facing open sides of the Klammermäuler. Subsequently, these two expansion clamps 14 are equally moved apart in opposite directions for spreading the now upper transverse edge of the laundry article.

As a result of the transfer of the laundry item to the centrally positioned expansion clamps 14 of the Spreizklammerpaars the garment after spreading the front or upper transverse edge is already centered in front of the feed conveyor 17. The laundry article can then be transferred from the expansion clamps 14 directly to the front end of the feed conveyor 17 by depositing a transverse front edge region adjoining the front transverse edge of the laundry article onto the front region of the feed conveyor 17 or a laying bar associated with the feed conveyor 17.

In accordance with the invention, laundry items are transferred from each of the two outer loading stations 11 to two nearest free expansion clips 14 of a pair of spreader clips. This transfer process clarify the 8 to 12 in connection with the right loading station 11 shown in the cited figures.

In the starting position ( Fig. 8 and 9 ) is the transfer bracket pair 21 at the outer, lower end of the rail 23 behind the two corner finders 19 (FIG. Fig. 9 ). In this position, the pair of transfer staples 21 pick up a piece of laundry from the corner finders 19 so that each transfer staple 20 retains a corner of the front transverse edge of the garment.

From the home position, the transfer brackets 20 of the transfer bracket pair 21 are moved together near the center of the delivery conveyor 17. This results in a near-mid transfer of the laundry item from the transfer bracket pair 21 to a pair of expansion brackets 14. In this case, the respective transfer bracket pair 21 passes on the oblique rail 23 and the rear end 26 thereof. This end 26 of the rail 23 is located above and in the feed direction 10 to the spreader 12 towards the lower end thereof. As a result, the rail 23 is obliquely directed in three-dimensional space, and indeed as well as the rail 24 of the left loading station 11, which, however, is mirror-inverted to the rail 23.

The upper, rear end 26 of the rail terminates at a distance from the end 25 of the middle rail 22. Therefore, the pair of transfer brackets 21 moved to the end 26 of the rail 23 are spaced apart from the vertical longitudinal center plane of the input machine. At this off-center location, the laundry item is transferred from the transfer clamps 20 of the transfer bracket pair 21 to the already trailing, waiting or later behind the transfer bracket pair 21 spread clamps 14 of a pair of expansion clamps closest to the transfer point ( Fig. 10 and 11 ).

After the expansion clips 14 of the Spreizklammerpaars have taken the laundry from the pair of transfer staples 21 and clamped it to opposite corners of a front transverse edge, the expansion clamps 14 are moved apart to stretch the front transverse edge of the garment. In this case, the (left) expansion clamp 14 located at a distance next to the vertical longitudinal center plane of the device lays a greater distance than the other (right) expansion clamp 14 of the spreader clip pair holding the laundry article further from the longitudinal center plane. In particular, the expansion clamp 14, which lies closer to the vertical longitudinal center plane, has to travel through the longitudinal center plane in order to extend the front transverse edge of the item of laundry and to spread out the item of laundry. The different lengths of travel of the expansion clamps 14 of the Spreizklammerpaars are chosen so that the laundry held by them when extending the transverse edge is also centered in front of the feed conveyor 17 centered. Subsequently, the transfer of the laundry item from the Spreizklammern 14 as well as the previously described in connection with the transfer of the laundry item to the Spreizklammern 14 from the rail 22 of the middle loading station 11.

As a result of the central process of the transfer bracket pair 21 of the outer loading station 11 before the transfer of a respective item of laundry to a pair of Spreizklammerspreizner 12, the travel of that Spreizklammer 14, which must go to stretch and spread the respective laundry over the center of the device or input machine, lower , Thus, the difference of the travel paths of the Spreizklammern 14 of a respective laundry holding Spreizklammerpaars when transferring middle of the laundry from Transferklammerpaar 21 to the Spreizklammerpaar smaller compared to the transfer of the respective laundry item to the Spreizklammerpaar directly behind the respective off-center loading station 11. Thus, the cycle time for Spread and center centering of the respective laundry reduced.

The transfer bracket pairs 21 on each of the rails 22, 23 and 24 and the expansion brackets 14 of the spreader 12 lie in two different parallel planes (FIG. Fig. 11 ). However, these levels are as close together as possible, so that the expansion clamps 14 can pass the transfer brackets 20 and their slides, but the transfer of the corners of the respective laundry from Transferklammerpaar 21 to the Spreizklammern 14 is reliably possible. Due to the fact that the transfer clamps 20 can run along the expansion clamps 14, it is possible that several or even all pairs of transfer clamps 21 are located at the upper end 25, 26 of the respective rail 22, 23 or 24 without colliding thereby ( Fig. 12 ). Also, the expansion brackets 14, both empty expansion brackets 14 as well as laundry carrying expansion clips 14, on the transverse rail of the spreader 12 behind the transfer bracket pairs 21 pass unhindered. By this another independent invention performing independent mobility of the transfer bracket pairs 21 and Überholmöglichkeit between the transfer brackets 20 and the Spreizklammern 14 and the cycle time of the input machine is reduced because, for example, during an ongoing spreading of a piece of laundry the next piece of laundry from a transfer bracket pair 21 already in a transfer position can be moved to the next and / or other Spreizklammerpaar towards the center of the feed conveyor 17. Also, the spreading of a transverse edge of a next piece of laundry can already begin when the transfer of laundry this piece of laundry to the expansion clamps 14 transfer pair 21 is still in the transfer position.

According to the loading stations 11, the spreader 12 and the transfer bracket pairs 21 are pivotally mounted on a frame of the input machine.

From one in the Fig. 1 shown operating position, the loading stations 11 together with the spreader 12 and the transfer bracket pairs 21 are pivoted up into a in the Fig. 2 For this purpose, the loading station 11, the spreader 12 and the transfer bracket pairs 21 with their associated rails 13, 22, 23, 24 mounted on a pivoting device 59.

The in the Fig. 1 and 2 shown pivoting device 59 has in the region of opposite longitudinal edges or sides of the feed conveyor 17 via one in the present case L-shaped rocker 60. The two opposing rockers 60 are pivotable at a free end about a rotation axis 61 on opposite side walls 62 of the frame of the input machine stored. The two opposite longitudinal edges of the feed conveyor 17 associated swing 60 of the pivoting device 59 are connected by transversely to the feed direction 10 extending cross member 63 to a three-dimensional frame structure with each other. This framework also serves to fix the rails 13 of the spreader 12, the rails 22, 23, 24 of the transfer bracket pairs 21 and optionally also the loading station 11 on the pivoting device 59th

The loading station 11, the spreader 12 and the transfer bracket pairs 21 are pivoted by the pivoting device 59 in an inoperative position, that then at least one operator, the front end 16 of the feed conveyor 17 is freely accessible, for example, manually to grow one of the input machine downstream defect Serving oilcloths on the front of the feed conveyor 17 hang. After the growth of the defect is completed, by pivoting back the pivoting device 59, the loading station 11, the spreader 12 and the transfer bracket pairs 21 again in their in the Fig. 1 swung back operating position shown.

The inventions described above are suitable for all types of input machines, and are therefore not limited to the device or input device described above and shown in the figures. The inventions are also suitable for devices or input machines with only one, two or even more than three loading stations. <B> LIST OF REFERENCES: </ b> 10 feed 37 sidewall 11 loading 38 support means 12 spreading 39 obertrum 13 rail 40 laundry 14 expansion clamp 41 Umlenktrommel 15 carriage 42 Cross-border area 16 front end 43 angle 17 feed conveyor 44 strand 18 loading conveyor 45 idler pulley 19 corner Finder 46 Umlenktrommel 20 transfer clamp 47 Umlenktrommel 21 Transfer of parentheses 48 strand 22 rail 49 upper edge strip 23 rail 50 lower edge strip 24 rail 51 obertrum 25 The End 52 conveyor belt 26 The End 53 Umlenktrommel 27 Belt conveyors 54 Umlenktrommel 28 Belt conveyors 55 suction box 29 placing area 56 top wall 30 The End 57 perforation 31 roller 58 axis of rotation 32 roller 59 Pivot means 33 nip 60 wing 34 lateral surface 61 axis of rotation 35 gutter 62 Side wall 36 front 63 crossbeam
