Abstract

A method and device providing that the corners of a respective laundry item are transferred one by one from a conveyor to spreading clamps of a pair of spreading clamps at the same position in each case. The respective conveyor therefore only requires a single circulatory track. Laundry items in commercial laundries are fed by at least one conveyor to spreading clamps of an input machine. In this case, each corner delimiting a front edge of the laundry item is held by a clamp of the conveyor. The respective conveyor is usually branched, in order for the corners to be transferred at the same time to the two spreading clamps of a pair of spreading clamps. Thus, the respective conveyor must have a branched track system with appropriate switches.

First claim

What is claimed is:

1. A method for the transport and/or the spreading of laundry items hanging on clamps, preferably for the purpose of transferring the laundry items to an input machine, wherein the respective laundry item hanging with adjacent corners of an edge in clamps of at least one conveyor is transferred to two spreading clamps of a spreading device of the input machine, comprising:
transferring the adjacent corners of the laundry item concerned one after the other from the clamps to the two spreading clamps of the spreading device,
wherein the transfer of the laundry items from consecutive clamps of the respective conveyor to the spreading clamps is performed in a successive bit by bit manner, and
wherein the respective laundry item is transferred to the two spreading clamps of a pair of spreading clamps by such successive or consecutive clamps of the respective conveyor which hold the adjacent corners of the edge of the laundry item.

2. The method as claimed in claim 1 , wherein the clamps of the respective conveyor transfer the adjacent corners of the edge of the laundry item delimited by said clamps one after another or in succession to the two spreading clamps of the respective pair of spreading clamps at the same position, wherein the two spreading clamps are driven in alternation to this position for the successive transfer of the respective corner from the clamps of the respective conveyor, which are driven one after another to the position, to the spreading clamps of the respective pair of spreading clamps, which spreading clamps are likewise driven one after another to the position.

3. The method as claimed in claim 2 , wherein the corner is transferred to the respective waiting spreading clamp of the pair of spreading clamps as the clamps of the respective conveyor, which hold the one corner of the laundry item concerned, pass by a spreading clamp of the input machine, which spreading clamp has been driven to the position of transfer as the clamps, with the corners of the laundry item concerned located therein, pass by the spreading clamps which have momentarily stopped at the position.

4. A device for the transport and/or the spreading of laundry items hanging on clamps, preferably for the purpose of transporting laundry items hanging on clamps to an input machine, comprising:
at least one conveyor, which has at least one circulating track running along its conveying section, on which run successive clamps, each for one corner of the laundry item concerned, wherein the at least one track is led to the input machine for transferring adjacent corners of an edge of the respective laundry item to spreading clamps of at least one pair of spreading clamps of the input machine,
wherein the clamps assigned one after another to the track are configured to hold adjacent corners of the edge of the laundry item, and are driven in succession along a respective spreading clamp of the pair of spreading clamps.

5. The device as claimed in claim 4 , wherein the clamps of the respective conveyor are driven one by one along and/or past the same position of the input machine, in each case along and/or or past spreading clamps of least one pair of spreading clamps of a spreading device of the input machine which are held ready at the same position.

6. The device as claimed in claim 5 , wherein all clamps of the respective conveyor are equally configured as double clamps with two spaced-apart individual clamps for jointly holding a corner of the respective laundry item.

7. The device as claimed in claim 6 , wherein an inner distance of the two individual clamps of each clamp or double clamp is somewhat larger than a width of the respective spreading clamp of the spreading device.

8. The device as claimed in claim 4 , wherein the track of the respective conveyor is realized as a single track or single line, along its entire course, and/or the track of the respective conveyor is led to the spreading device of the input machine in such a manner that a section of the respective corner of the laundry item held in a stretched manner between the individual clamps of the respective clamps of the conveyor concerned are transported into an open end of a clamping mouth of the respective spreading clamp by the respective conveyor.
