Definitions

  • the invention relates to a method for supplying laundry items to a defect or the like according to the preamble of claim 1. Furthermore, the invention relates to a device for feeding laundry items to a defect or the like according to the preamble of claim 8.
  • Laundry items are fed to a defect or the like with a so-called input machine.
  • Such input machines have a spreading device which, viewed in the feed direction, is arranged downstream of a feed conveyor and an input conveyor.
  • the spreader spreads the laundry items in front of the feed conveyor and places them either directly on the upper run of the feed conveyor or on an associated with the feed conveyor Ablegeelf. From the feed conveyor, the laundry is transferred to the input conveyor, which transports it to the defect or other laundry treatment machine.
  • the invention has for its object to provide a method and apparatus for supplying laundry items to a defect or the like, which allow automatic removal of laundry items having thickening in uninterrupted operation of the input machine and the subsequent laundry treatment machines, in particular shortage.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is envisaged to discharge laundry items having a thickening through a gap between the supply conveyor and the input conveyor or the input conveyor and the defect or the like. Such a gap can be formed and reversed during the operation of the deficiency line, in particular the input machine. A temporary stopping of the feed conveyor and / or the input conveyor is therefore no longer necessary in the method according to the invention. In particular, no operator needs to manually remove thickened items from the input conveyor or feed conveyor.
  • the gap is preferably formed by shortening an upper run of the input conveyor and / or the feed conveyor receiving the laundry items. In this way, the required for discharging thickened laundry items gap can form quickly and easily. Above all, the gap can be formed reliably and precisely by shortening the upper run, which ensures a targeted discharge of laundry items having thickening.
  • the method according to the invention is developed in such a way that at least one detection means detects the item of laundry having a thickening and this item of laundry is deliberately discharged by forming the gap immediately in front of the edge of the detected item of laundry located in the feed direction.
  • the detection means can thicken the laundry by scanning, weighing, image recognition or the like. If the detection means determines a thickening of a piece of laundry, it is forwarded to its control, which makes the formation of the gap in a timely manner, so that the item of laundry can be specifically released.
  • the gap can also be formed when the front edge of the laundry item having a thickening has already passed slightly past the gap to be formed later, so that the gap is formed under the laundry item and the laundry item falls through the gap in a double-layered manner by approximately centering buckling. In this way, a particularly rapid discharge can be achieved, it being ensured that the gap is closed in good time before reaching the next, no thickening piece of laundry, even if the laundry items are immediately successively on the Zufoundforderer or input conveyor.
  • An advantageous development of the method provides that a closing of the gap is controlled by the rear edge of the currently discharged by the gap piece of laundry or the leading edge of a next piece of laundry without thickening. By such an edge control a pinpoint closing of the gap is ensured, thereby ensuring that a non-thickening garment will not be accidentally ejected.
  • each discharged by the gap laundry with a thickening under the gap is collected, in particular by a conveyor that carries it away. This leads to a complete automation of the removal of thickened laundry items.
  • An apparatus for solving the above-mentioned problem has the features of claim 8.
  • this device is provided to temporarily shorten a top strand of the input conveyor and / or of the supply conveyor carrying the items of laundry in a temporally controlled manner.
  • This shortening of the upper run leads to a gap between the Input conveyor and the following in the feed direction deficiency or the like or between the input conveyor and the feed conveyor.
  • both the upper run of the input conveyor and the feed conveyor can be shortened.
  • the upper runs of both the infeed conveyor and the infeed conveyor can be shortened starting from their mutually aligned ends. This reduces the amount of shortening of the upper run of the feed conveyor and the input conveyor, so that the gap formation and the gap reversal can be very rapid.
  • a deflection drum at one end of the upper run of the input conveyor, in particular on the end of the upper run of the input conveyor pointing towards the defect or the like, to form the gap for shortening the upper run against the feed direction.
  • a preferred embodiment of the device provides to store the displaceable tail pulley on a longitudinal guide.
  • the longitudinal guide in turn led slidably associated with a support frame of the input conveyor. Due to this type of displaceability of a deflection drum of the input conveyor, the distance between the deflection drum at opposite ends of the input conveyor can be reduced for discharging laundry items having thickened portions, a skewing of the displaceable deflection drum being avoided by the longitudinal guide, thereby ensuring reliable straight-line guidance of the belts of the input conveyor shortened upper strand and while shortening and reversing the shortening of the upper strand is retained.
  • the longitudinal guide of at least one linear drive which is preferably at least one pressure cylinder, in and against the feed direction relative to the support frame of the input conveyor displaceable. This ensures an automatic shortening of the upper strand as well as an equally automatic reversal of the shortening.
  • the input conveyor is assigned a compensation drum. This serves to keep the straps of the input conveyor when moving the movable guide drum tight, whereby the straps are still driven circumferentially, in particular for discharging thickened laundry by the gap formed as a result of reducing the length of the upper run of the input conveyor.
  • a balance shaft is provided.
  • a pivot arm is associated with each of the opposite ends of the balance shaft.
  • the pivot arms are pivotable in dependence on the travel of the longitudinal guide relative to the support frame.
  • the pivot arms of the displaceable tail pulley having longitudinal guide may be coupled in a gear with the support frame (also called support frame) to couple the pivoting path of the pivot arms to the travel of the longitudinal guide and hereby synchronize, whereby a misalignment of the longitudinal guide is mechanically avoided or compensated.
  • the input conveyor for each web has an independently movable in and against the feed direction tail pulley.
  • a gap for discharging a piece of laundry having a thickening can be created for each web independently of the other webs.
  • the remaining tracks can continue to perform the lack of suitable laundry items of defect or other laundry machine.
  • each individual individual lane independently with a separate linear guide with at least one linear drive and a compensation drum and optionally a balance shaft. It is the same as the input conveyor on each lane designed for independent removal of a thickening having laundry per lane.
  • a particularly advantageous device has under the gap on a discharge conveyor for discharged through the gap laundry with a thickening. So not only each laundry item having a thickening automatically ausschleusbar, but also automatically conveyed.
  • a common discharge conveyor can be assigned to all lanes, so that thickened laundry items that are discharged on each web, can be dropped onto the same discharge conveyor and transported away from this ,
  • the discharge conveyor is designed to remove discharged laundry items transversely to the feed direction.
  • Such a discharge conveyor can be arranged without additional space under the need to be formed gap.

  • the input conveyor 14 is designed as a so-called stretch conveyor with a cover conveyor 16 arranged above the input conveyor 14.
  • the feed conveyor 13, the input conveyor 14 and the cover conveyor 16 have about several in the figures only partially shown adjacent endless straps 17, 18 and 19.
  • the expansion clamps of the spreading device 10 hold opposite corners of a front edge of the laundry item 20 shown only in some figures. By moving apart the expansion clamps, the laundry item 20 is spread out in front of the feed conveyor 13, in particular spread or stretched. The hanging down from the Sp Dr Drklammern lower part of the spread laundry article 20 is sucked into a suction chute 21 in front of and below the feed conveyor 13. At the upper end of the suction chute 21, a flap 22 pivotable about a horizontal axis of rotation is arranged. This serves to the thickness scanning of the laundry item 20th
  • the laundry item 20 After the laundry item 20 has been sucked into the suction chute 21, the laundry item 20 is placed on the delivery bar 15 with the front edge stretched between the expansion clamps, whereby the laundry item 20 is transferred from the spreading clamps of the spreading device 10 to the delivery bar 15.
  • the Ablegemann 15 is then moved in the feed direction 11 on the feed conveyor 13 and thereby pass the front, stretched transverse edge of the laundry article 20 of the Ablegeang 15 to the feed conveyor 13.
  • the feed conveyor 13 then transports the item of laundry 20 in the feed direction 11 to the input conveyor 14, the rear part of the item of laundry being pulled past the flap 22 past the suction chute 21.
  • the laundry item 20 between the upper run 23 of the input conveyor 14 and a lower run 24 of the cover conveyor 16 in the feed direction 11 are transported to the defect 12 and entered into the same after passing the front end 25 of the input conveyor 14.
  • the input conveyor 14 is formed. Its length is changeable seen in the feed direction 11, in such a way that the front end 25 of the input conveyor 14 against the feed direction 11 from an input side 26 of the shortage 12 is moved away. In this way, temporarily a gap 27 (FIG. Fig. 2 ) between the front end 25 of the input conveyor 14 and the input side 26 of the defect 12 are formed.
