Description

The invention relates to devices for supplying laundry items to a defect or the like according to the preamble of claim 1 or 7. Furthermore, the invention relates to methods for supplying laundry items to a defect or the like according to the preamble of claim 9 and 12, respectively.

The feeding of laundry items to a defect or the like is done with a so-called input machine. Such an input machine has a supply conveyor optionally having a delivery bar which supplies the respective laundry item with the defect or the like. A spreading device is provided in front of the feed conveyor, which has expansion clamps for holding opposite corners of a front edge of the laundry item and spreads, in particular extends, the front edge of the laundry item prior to placement on the feed conveyor or the lay-up bar. For input machines with high input power, several loading stations are preferably arranged in front of the spreading device. Each loading station has at least one pair of loading clamps in which manually opposite corners of the front edge of the laundry item are hung. From the Beladeklammern the corners of the laundry are then automatically transferred to the expansion brackets of the spreader.

There are input machines of the aforementioned type are known in which the expansion clamps for taking over the corners of the laundry item from the loading clamps are pivotable in a position with Klammermäulern open at the bottom. As a result, the laundry item can spread out in a straight line hanging from the Spreizklammern state. In the known input machines pivoting the expansion clamps is solved quite expensive. In addition, the loading clamps hinder the transfer of the laundry article to the Spreizklammern the immediate method of Spreizklammern. Finally, it can happen in the known input machines that the always slightly sagging middle front edge of the laundry item is retained by a front end of the feed conveyor or the laying bar and thereby increases the sag. The laundry is then placed on the feed conveyor or lay-up bar with this increased slack. This can lead to wrinkles in the garment, which suffers from the lack of quality.

Based on the above, the present invention seeks to provide methods and apparatus for easy feeding of laundry items to a defect or the like, thus creating the conditions for a good quality defect.

An apparatus for achieving this object has the features of claim 1. Accordingly, it is provided that each expansion clamp is pivotable about two parallel pivot axes. Preferably, these two pivot axes are horizontally oriented transversely to the feed direction of the laundry items to the defect or the like. As a result of the two pivot axes, the expansion clamps can be pivoted from a takeover position of the laundry items with low space required Klammernmäulern in a depositing, in which the Klammermäuler run in the direction of the upper strand of the feed conveyor or a laying surface of the Ablegeleiste. The expansion clamps can thus take over the respective item of laundry just hanging from the loading clamps, without a front edge area extending from the front edge of the item of laundry being bent relative to the plane in which the item of laundry hangs down from the expansion clamps. In addition, the front edge region of the item of laundry can be reoriented so that the front edge region of the item of laundry is aligned with the upper run of the infeed conveyor or with the support surface of the layup bar and thus can be deposited essentially without transition onto the infeed conveyor or the take-off bar ,

An advantageous development of the device provides that the respective expansion clamp is connected via a pivot arm with a Spreizklammerträger and the two parallel pivot axes are assigned opposing ends of the pivot arm. Such a swivel arm can be easily realized. The assignment of the two pivot axes to the opposite ends of the pivot arm results in the formation of a double joint, whereby the desired movements of the expansion clamps can be realized in a simple and reliable manner. The movements of the expansion clamps are not limited only to pivoting movements; Rather, the expansion clamps can also make movements in the feed direction, ie to the feed conveyor or the Ablegeleiste and vice versa.

Preferably, with a pivot axis of the swivel arm is pivotally mounted on the Spreizklammerträger, while the other pivot axis connects the respective Spreizklammer hinged to the pivot arm. In this way, a "Z" -shaped configuration is brought about, with which the pivoting clamps can optimally fulfill the requirements placed on a reliable takeover of the item of laundry from the loading clamps and the placing of the item of laundry onto the feed conveyor or the delivery bar.

A particularly advantageous development of the invention provides to connect the pivot axes by a stationary strand, preferably an endless strand such as a belt, a rope or the like. As a result, the expansion clamps are additionally pivotable about the pivot axis, with which the expansion clamps are connected to the pivot arm when pivoting the pivot arm. By the at least one strand, the pivoting of the respective expansion clamp is coupled to the associated end of the pivot arm with the pivoting of the pivot arm and / or synchronized. It is preferably provided to pivot the expansion clamp in the opposite direction to the pivot arm, so bring about a buckling. Alternatively or additionally, it is conceivable that the Verschwenkwege in a certain, preferably unequal relationship to each other. In this way, the movement of the Spreizklammern corresponding to the needs can be realized, in particular superimposed motion sequences by the respective Spreizklammer is moved on a partial circular path on the Spreizklammer associated free end of the pivot arm while the Spreizklammer additionally pivoted about the second pivot axis at the free end of the pivot arm becomes.

According to an advantageous development of the device, a strand, for example a belt, belt or rope, preferably a stationary and / or non-driven strand or belt or the like, is assigned to the pivot axes. Preferably, the pivot axes are connected by the strand or belt or the like.

On each pivot axis at least one disc is arranged non-rotatably. The discs on different pivot axes are coupled together by the strand. Preferably, the strand is formed as a non-revolving endless endless belt, belt or belt. The strand, the belt, the belt or the belt are endlessly guided around the disks and thereby form a belt arrangement, in particular a non-driven belt, rope or belt drive. It is thus easily a coupling of the pivoting of the pivot arm about the pivot axis at the Spreizklammerträger associated end with the pivoting of the expansion clamp around the free end of the pivot arm can be brought. Due to the at least one preferably circulating strand, no additional drive is required for pivoting the expansion clip about the free end of the pivoting arm associated therewith. The at least one strand transmits the pivoting movement of the swivel arm to the expansion clamp and pivots it about the free end of the swivel arm. It is characterized only a pivot drive for the swing arm required.

Another device for the solution of the above-mentioned object, which may also be a preferred embodiment of the device described above, has the features of claim 7. In this device, it is provided to raise and / or lower the expansion clamps. The lifting and / or lowering of the expansion clamps preferably takes place on a vertical path or a path which runs perpendicular to the plane of the upper run of the feed conveyor or perpendicular to the laying surface of the laying bar. As a result, the spreading clips can be moved out of the area of the loading clamps after taking over the item of laundry from the loading clamps for depositing a leading edge region of the respective item of laundry onto the feed conveyor or the depositing strip while the loading clamps are still in the transfer position. Alternatively or additionally, the front edge of the item of laundry held between the expansion clamps, which naturally always has a slight slack even when the front edge is stretched by the expansion clamps, can be lifted over the front end of the supply conveyor or the delivery bar without the lowest point of the one sag having the front edge of the garment with the feed conveyor or the Ablegeleiste collided.

When arranged on carriages Spreizklammerträgern for holding the Spreizklammern it is provided, the Spreizklammerträger with the Spreizklammern on a vertical path or perpendicular to the plane of the upper strand of the feed conveyor or the laying surface of the Ablegeleiste running path up and down. In such an embodiment of the device, it is possible to additionally move the expansion clamps relative to the Spreizklammerträger, in particular to pivot.

A method for solving the above-mentioned problem comprises the measures of claim 9. Accordingly, it is provided to lower the Spreizklammern after passing the laundry from the Beladeklammern with the laundry. As a result, the leading edge region of the item of laundry held between the expansion clips is moved out of the region of the loading clips, so that the expansion clips can be moved to spread the item of laundry and the loading clip can remain in its transfer position of the item of laundry to the expansion clips. This increases the performance of an input machine operating according to this method.

Preferably, the loading clamps are raised for transferring the respective item of laundry to the expansion clamps to the same while the held by the Beladeklammern corner regions of an opposite front edge of the laundry in below open Klammermäuler moved the expansion clamps. After the expansion clamps have been closed and thereby hold the corner regions of the front edge of the laundry, there is an opening of the Beladeklammern. The Klammermäuler the Beladeklammern are open at the bottom, so that by lowering the Spreizklammern with the laundry held on this piece of the corner areas of the laundry are pulled down from the Beladeklammern. The loading clamps remain in the transfer position of the laundry item to the expansion clamps. By lowering the Spreizklammern can be moved with the laundry in spite of the whereabouts of Beladeklammern in the transfer position.

Another method for solving the above-mentioned object, which may also be a preferred development of the method described above, comprises the measures of claim 12. This method makes it possible to raise the expansion brackets with it before laying the laundry item, so that the stretched by the expansion clamps leading edge of the laundry item is located at a distance above an upper run of the feed conveyor or above a laying surface of the Ablegeleiste. As a result, the feed conveyor or the diverter bar do not affect the leading edge of the item of laundry when advancing to the feed conveyor or to the diverter bar.

Preferably, it is provided that the Spreizklammern so far raised before placing a outgoing from the spread front edge of the laundry front laundry section on the feed conveyor or the Ablegeleiste that the lowest point of the front edge of the laundry over the upper run of the feed conveyor or the laying surface of the Ablegeleiste is lifted. This allows the Spreizklammern move the front Wäschestückbereich despite the naturally always present slight slack of the front edge of the laundry over the upper run of the feed conveyor or the depositing surface of the Ablegeleiste without this collides the front edge of the laundry and thereby increase the sag of the front edge of the garment. As a result, the laundry item with almost straight leading edge can be placed on the infeed conveyor or the depositing bar. This ensures a wrinkle-free supply of the garment to the defect, whereby an optimal quality of defects is guaranteed.

A further preferred development of the method provides that the expansion clamps are lowered for laying down the front laundry section with the front edge of the laundry item on the feed conveyor or the Ablegeleiste as soon as the leading edge of the laundry in the feed seen behind a front end of the feed conveyor or the Ablegeleiste located. The front laundry section can thus be stored substantially seamlessly on the upper strand of the feed conveyor or the depositing surface of the Ablegeleiste, which reduces the risk of warping in particular the front edge of the laundry item when depositing on the Ablegeleiste or the feed conveyor and thereby also for storing the laundry with almost straighter Leading edge contributes to the Ablegeleiste or the feed conveyor and thereby contributes to increase the defect quality of the laundry article.

The device shown in the figures is a so-called input machine. This serves to supply laundry items, not shown in the figures, and especially large items of laundry, a defect or other laundry treatment device. The defect is not shown in the figures. It is arranged in the feed direction 10 behind the device, namely the input machine. The input machine shown here has a feed conveyor 11 formed by at least one belt conveyor, which transports a laundry item in the extended state in the feed direction 10 to the shortage located behind the feed conveyor 11 or another laundry treatment device. In the case of the input machine shown here, the feed conveyor 11 has an ejection bar 12. In this case, a piece of laundry is stored with a front of the laundry piece outgoing front laundry section on the Ablegeleiste 12 and then stored by the Ablegeleiste 12 during a relative movement thereof to the feed conveyor 11 on an upper run 13 of the feed conveyor 11. The invention is not limited to such input machines. The invention is also suitable for input machines without a delivery bar 12, in which the front laundry section is placed directly on the upper run 13 of the feed conveyor 11.

As seen in the feed direction 10, a spreader 14 is arranged in front of the feed conveyor 11. The spreader 14 has a transversely to the feed direction 10 extending rail 15, which extends over the entire width of the feed conveyor 11th extends. On the rail 15 at least two carriages 16 are transversely movable to the feed direction 10. Under each carriage 16, a Spreizklammer 17 is attached to a Spreizklammerträger 18. In the illustrated embodiment, two equally trained Spreizklammern 17 are provided. However, it is also conceivable that the spreader 14 has more than two expansion clamps 17 which are movable on the same rail 15 or preferably separate parallel rails. The two expansion clamps 17 of the input machine shown here can be moved independently of each other along the rail 15 transversely to the feed direction 10 by means of different drives. This results in spreading, preferably spreading, of a front edge of the item of laundry held at opposite corners or corner areas by the expansion clamps 17 and centering the spread item of laundry in front of the feed conveyor 11.

The input machine has seen in the feed direction 10 before the spreader 14 via preferably a plurality of identical loading stations 19. The number of loading stations 19 may be arbitrary. For example, four equal loading stations 19 are provided, in each case two loading stations 19 in pairs on opposite sides of the input machine.

Each of the loading stations 19 of the same design has a conveyor with a gradient rising obliquely towards the expansion clamps 17 for the mechanical lifting of a laundry item in each case. A lower free end of the conveyor is located in the region of a loading point 20. An opposite upper end of the conveyor corresponds to the spreader 14, in particular the Spreizklammern 17. The Beladestationen 19 shown here are each provided with two contiguous Beladeklammern 21. However, the loading stations 19 can also each have several pairs of two loading clips 21 each. The Beladeklammern 21 are hochfahrbar from the conveyor of the lower loading point 20 to the expansion brackets 17 for transferring the laundry item to the expansion clamps 17 and then again empty to the loading point herunterfahrbar. In the pairwise connected Beladeklammern 21 each loading station 19 is manually a laundry with opposite corners or corner regions of the front edge of the laundry suspended.

The two loading clamps 21 of each pair are jointly and fixed, in particular non-pivotable, arranged on a carriage 22, which can be moved up and down by the conveying device of the loading station 19 along a slightly obliquely directed path 23. The Klammermäuler the Beladeklammern 21 are open at the bottom and otherwise aligned parallel to the slightly inclined web 23 of the conveyor of the respective loading station 19.

Each expansion clamp 17 is pivotally mounted about two parallel pivot axes 24 and 25 on Spreizklammerträger 18. Both pivot axes 24 and 25 extend horizontally and transversely to the feed direction 10, ie parallel to the rail 15 of the spreader 14. The pivot axes 24 and 25 are at opposite ends of the respective expansion clamp 17 with the Spreizklammerträger 18 connecting arm 26. Each pivot arm 26 has two from each other spaced, parallel elongated tabs 27 on. An upper end of the swing arm 26 is pivotally connected to the Spreizklammerträger 18 about the pivot axis 24. A lower end of the swing arm 26 is connected to the swiveling about the pivot axis 25 17 Spreizklammer. The pivot axes 24 and 25 are spaced approximately the length of the pivot arm 26 from each other. The pivot arm 26 is pivotable about the pivot axis 24 relative to the Spreizklammerträger 18 by a linear drive, in the illustrated embodiment, a pneumatic cylinder 28.

It is provided according to the invention, during pivoting of the pivot arm 26 about the upper pivot axis 24 at the same time the expansion clamp 17 at the lower end of the pivot arm 27 to pivot relative to the same about the pivot axis 25. The pivoting of the expansion clamp 17 about the free end of the pivot arm 26 is coupled to the pivoting of the pivot arm 26. When pivoting the pivot arm 26 about the pivot axis 24 so pivotally takes place the pivoting clamps 17 about the pivot axis 25 relative to the pivot arm 26 instead. In particular, so takes place a synchronization of the pivotal movement of the pivot arm 26 with the pivoting of the expansion clip 17. The angle at which the expansion clamp 17 is pivoted about the pivot axis 25 during pivoting of the pivot arm 26, is in a fixed ratio to the requirements of the angle to the the pivot arm 26 is pivoted about the pivot axis 24.

By the two spaced, parallel pivot axes 24 and 25 at opposite end portions of the pivot axis 26, the expansion clamp 17 is pivoted on a circular path about the pivot axis 24 at the upper end of the pivot arm 26 and the other about the pivot axis 25 at the lower end of the pivot arm 26 , The respective expansion clip 17 thereby results in pivoting the Swivel arm 26 a superimposed movement about the pivot axis 25 and on a circular path about the pivot axis 24 from.

The coupling of the pivoting of the expansion clamp 17 with the pivoting of the pivot arm 26 is effected by at least one pivot axis 24 and 25 associated, in particular the pivot axes 24 and 25 connecting, stationary or non-driven strand. The strand is formed in the embodiment shown by a toothed belt 31, which is guided around the pivot axes 24 and 25 associated discs 29 and 30, wherein each pivot axis 24 and 25 is associated with a disc 29 and 30 respectively. At the location of the toothed belt 31, another belt, for example a flat belt, a round belt or a V-belt may also be used. Also conceivable are a rope or a chain to form the strand.

Both discs 29, 30 are mounted non-rotatably on the pivot axes 24, 25. As a result, the disc 29 on the pivot axis 24 relative to the Spreizklammerträger 18 is non-rotatable, while the disc 30 on the pivot axis 25 relative to the Spreizklammer 17 is non-rotatable. Due to the fixed arrangement of the discs 29, 30 on the pivot axes 24 and 25 of the pivot arm 26 is pivotable when pivoting about the pivot axis 24 relative to the discs 29 and 30. As a result, the drive-less toothed belt 31 rolls during pivoting of the pivot arm 26 on the disc 29 and thereby rotates the lower disc 30 against the pivoting direction of the pivot arm 26. This illustrate in particular the Fig. 4 and 6 : Starting from the position in the Fig. 4 the pivot arm 26 is pivoted clockwise by approximately 90 °. In this case, the pivot bracket 17 is pivoted counterclockwise about the pivot axis 25, and that to a larger pivot angle, ie a pivot angle of about 90 °. This is achieved by a fixed ratio of the non-driven toothed belt arrangement formed by the discs 29 and 30 and the toothed belt 31 in the region of the pivot arm 26. The greater pivot angle of the expansion clamp 17 is achieved with respect to the pivot arm 26 compared to the pivot angle of the pivot arm 26 relative to the Spreizklammerträger 18 by different sized slices 29 and 30, namely by a comparison with the disc 29 in diameter smaller disc 30 on the pivot axis 25th

The expansion clamps 17 are along a rectilinear vertical path, in particular a perpendicular to the laying surface of the Ablegeleiste 12 or the upper strand 13 of the feed conveyor 11 extending rectilinear path, up and down movable. This movement of Spreizklammern 17 each on a preferably vertical, straight axis can be done in various ways. For example, the Spreizklammerträger 18 along the vertical, rectilinear axis or web up and down movable under or be mounted on the carriage 16. But it is also conceivable, the Spreizklammerträger 18 in such a way that the pivot axis 24 for connecting the pivot arm 26 with the Spreizklammerträger 18 up and down is movable. This can be realized, for example, in a multi-part design of Spreizklammerträgers 18.

The method according to the invention will be explained below with reference to the device shown in the figures, namely input machine:

For transferring the item of laundry from this at opposite corners of the leading edge holding Beladeklammern 21 to the expansion clamps 17, the expansion brackets 17 are pivoted by the pivot arm 26 in such a position in which the lower open Klammermäuler the expansion clamps 17 parallel or approximately parallel to the web 23, on the Beladeklammern 21 are raised by the carriage 22 from the lower loading point 20 for transfer to the Spreizklammern 17. Then the open at the bottom Klammermäuler the Spreizklammern 17 rectified with the also below open Klammermäulern the Beladeklammern 21. By raising the Beladeklammern 21 with a piece of laundry from the lower loading point 20 along the slightly oblique rectilinear path 23 which held by the Beladeklammern 21 corner regions of the leading edge Then the spreader clips 17 are closed and then the loading clamps 21 are opened. As a result, the transfer of the laundry article from the loading clamps 21 to the expansion clamps 17 is completed.

The transferred to the Spreizklammern 17 laundry items is now slightly lowered with the Spreizklammern 17, to the extent that the laundry items, in particular the corner areas at opposite ends of the front edge of the laundry, are pulled out of the Klammermäulern the Beladeklammern 21 down. The loading clamps 21 remain in the end position, which they have assumed for transferring the item of laundry to the expansion clamps 17. After the lowering of the expansion clamps 17, the upper edge region of the item of laundry, in particular the corner areas thereof, are released from the loading clamps 21 by the web running on a vertical straight line or a web running parallel to the web 23 of the respective loading station 19, the laundry article is released from the expansion clamps 17 method, namely spread or spread in front of the feed conveyor 11 and centered to the feed conveyor 11 and the respective input track centered. After the item of laundry has been moved out of the expansion clamps 17 out of the influence of the empty loading clamps 21, the empty loading clamps 21 are moved back along the path 23 to the lower loading point 20 of the loading station 19.

As soon as the item of laundry has spread from the expansion clamps 17 in front of the feed conveyor 11 and centered, the expansion clamps 17 are prepared for the preparation of depositing the front laundry portion onto the delivery bar 12 (or for input machines without delivery bar 12 directly onto the supply conveyor 11) Fig. 3 and 4 takeover position of the laundry in the in the Fig. 5 and 6 shown Ableggestellung of the laundry on the lay bar 12 pivoted. For this purpose, the pivot arm 26 is pivoted clockwise about the pivot axis 24 to the Spreizklammerträger 18 of the pneumatic cylinder 28. In this case, forcibly guided by the belt belt 31 and the stationary disks 29 and 30 formed circulating belt assembly pivotally mounted on each pivot arm 26 Spreizklammer 17 pivots about the lower pivot axis 25 in the counterclockwise direction. The respective expansion clamp 17 is thus moved on the one hand on a circular path about the pivot axis 24, wherein the radius of the circular path is the distance of the pivot axes 24 and 25 and also the expansion clamp 17 is pivoted about the pivot axis 25. These superimposed movements of the Spreizklammer 17 takes place synchronized, so to speak, and caused by the pivotal movement of the pivot arm 26. The pivoting of the Spreizklammern 17 about the pivot axis 25 without an independent drive of the belt assembly. Rather, when pivoting the pivot arm 26 from the pneumatic cylinder 28, the pivoting of the expansion clamps 17 around the pivot axis 25 caused simultaneously and without its own active drive.

While in the transfer position of a piece of laundry, the expansion brackets 17 and the pivot arm 26 according to the Fig. 3 and 4 occupy a nearly stretched position, get to place the laundry on the Ablegeleiste 12, the Spreizklammer 17, the Spreizklammerträger 18 and the pivot arm 26 is an approximately Z-shaped double crooked configuration, as shown in the Fig. 5 and 6 is shown. In this configuration, the clamping mouth of the respective expansion clamp 17 which is open in the direction of the loading station 19 is aligned approximately parallel to the laying surface 32 of the laying bar 12. In the exemplary embodiment shown, with horizontally extending laying surface 32, consequently, the clamp mouths of the expansion clamp 17 are also approximately horizontally oriented for depositing the item of laundry onto the lay bar 12 (FIG. Fig. 2 ), preferably the Klammermäuler towards the open end can be slightly sloping with respect to the horizontal ( Fig. 6 ).

Before placing the front laundry section of the laundry article on the Ablegeleiste 12, the expansion clamps 17 are lifted with the laundry held by the same on the straight vertical or parallel to the web 23 extending path. Preferably, this is done during the spreading of the laundry article of the spreading device 14 by the taking place for moving out of the front edge of the laundry article from the loading chambers 21 lowering lowering of the expansion brackets 17 is reversed. The laundry item is raised by the expansion clamps 17 so far that the lowest point of the slightly between the Spreizklammern 17 sagging front edge of the garment or the front Wäschestückbereichs is slightly higher than the laying surface 32 of the Ablegeleiste 12. This can be from the pivoting of the Spreizklammern 17 in the horizontal angled front garment area despite the sag, so in particular as a result of the sag deeper middle area between the Spreizklammern 17, without colliding with the front end portion of the Ablegeleiste 12, namely at a short distance above the laying surface 32 of the Ablegeleiste 12.

After the between the Spreizklammern 17 approximately horizontally oriented front Wäschestückbereich of the by the pivoting of the pivot arms 26 and the Spreizklammern 17 with the approximately horizontally oriented front edge area on the laying surface 32 of the Ablegeleiste 12 passes, the Spreizklammern 17 by lowering on the rectilinear path with the pointing to the open end of the clamp mouth edge of the underside of the expansion clamps 17 completely or almost lowered to the laying surface 32 of the lay bar 12. As a result, the front laundry section, which is held between the expansion clamps 17 and is oriented almost horizontally, is deposited on the laying surface 32 of the lay-bar 12 substantially without transition. Subsequently, the expansion clamps 17 are moved apart after opening the Klammermäuler, thereby free the deposited on the laying surface 32 front laundry section. The laundry item can then pass unhindered with the extended front laundry section area between the Spreizklammern 17 by moving the Ablegeleiste 12 in the feeding direction 10 to the feed conveyor 12 and the same are stored on the upper run 13.
