Definitions

  • the invention relates to a method for feeding laundry to an input machine according to the preamble of claim 1 and the preamble of claim 6.
  • the fully automatic feeding of laundry items to input machines is divided into two fully automatic sections. Firstly, the items of laundry are pulled out of a laundry pile at the most convenient location with the aid of a camera and separated. Secondly, the individual items of laundry are, for the most part with the help of a camera, automatically entered in brackets with two adjacent corners of an edge and automatically transferred to loading or spreading brackets of the input machine. The spreading clamps hold the item of laundry in the adjacent corners of the edge and spread it before the item of laundry spread thereby is transferred from the input machine to a mangle or other laundry treatment machine.
  • the object of the invention is to create a method for feeding items of laundry to an input machine, which ensures a balanced relationship between the degree of automation and the cycle time.
  • a first method for solving this problem has the measures of claim 1. Accordingly, it is provided that the respective items of laundry are cached at least once after being separated and before being transferred to the input machine.
  • the at least one temporary storage creates buffers between successive work or handling steps. This can even out the procedure. In particular, the successive handling or work steps can thus be carried out continuously and / or continuously. Above all, this creates a prerequisite for a functioning sequence of automatic, semi-automatic and / or manual work or activities.
  • the buffering in at least one intermediate store compensates for discontinuities arising as a result of manual activities, so that automatic or semi-automatic activities can take place continuously, in that the at least one laundry storage leads to an evening of the piece of laundry flow.
  • the item of laundry with the corner from which it hangs is preferably transferred to the at least one store, in particular at least one clip thereof, by the separator and / or taken over by the store.
  • the provision of a corner of the respective item of laundry from Separator enables targeted storage and targeted further processing from the memory in a next handling step.
  • the laundry item provided by the separator hanging from a corner can be taken over both manually and automatically, preferably with exactly this corner.
  • An advantageous further development possibility of the method provides for the items of laundry to be sorted sorted into at least one store for sorted items of laundry, namely a sorting store.
  • the respective sorting store preferably has a plurality of storage tracks for each type of laundry. The sorted items of laundry can then be retrieved sorted by type from the respective storage path.
  • the sorted laundry items are preferably moved into the at least one sorting store from the intermediate store and / or at least one identification device.
  • the sorting preferably takes place when the laundry items are transferred from the intermediate store or the identification device into the at least one sorting memory, in that the laundry items are moved into the respective storage path of the sorting memory in a targeted manner, especially controlled by the identification device.
  • the respective item of laundry to be identified in front of the at least one sorting store, preferably with regard to at least one sorting criterion thereof.
  • Identification is preferably carried out by an identification device with, for example, an imaging device.
  • the identification of the respective item of laundry can be carried out by the identification device in the area of a buffer store in front of the at least one sorting store.
  • the items of laundry can then be sorted into the respective storage path of the sorting store and sorted in the respective storage path.
  • a further method for solving the problem mentioned at the outset which may also be a preferred development according to one or more of the claims 1 to 5 described above, has the measures of claim 6.
  • the automatic separator is provided one at a corner to hold the item of laundry held for forwarding to an identification device, at least one intermediate store, at least one sorting store and / or for manual transfer.
  • the respective item of laundry hangs freely down from a first corner held by the automatic separator.
  • This enables another (second) corner to be easily found and gripped manually.
  • it is easier for an operator to grasp the second corner if the item of laundry is held ready by the separator in such a way that the lower corner and / or the second corner of the freely hanging item of laundry hangs above the floor at an ergonomically favorable height.
  • At least one second corner of an edge of the laundry item which is adjacent to the first corner provided by the separator, is manually entered into a bracket.
  • the first corner can be automatically or manually entered in brackets.
  • the clip is, for example, at least one clip of an input machine that holds the item of laundry with adjacent corners of an edge, in particular a leading edge, and extends this edge.
  • An advantageous embodiment of the method provides for manually determining, in the area of the at least one intermediate store, the second corner of the edge of the laundry item adjacent to the first corner held in a bracket of the at least one intermediate store, and preferably also manually entering this second corner into the second bracket of the intermediate store to enter.
  • the second corner of the item of laundry which is difficult to automatically determine, especially in the case of large items of laundry, is determined manually and is thus entered into the second bracket of the intermediate store.
  • This has surprisingly proven to be reliable and, above all, faster than the automatic determination of the freely hanging second corner of the item of laundry and the automatic input of the latter into a second bracket.
  • the area of the at least one sorting store it is conceivable in the area of the at least one sorting store to manually determine the second corner of the edge of the laundry item, which is adjacent to the first corner held in a bracket thereof, and / or manually into the second bracket of the Enter sort memory.
  • the method provides for at least one of the adjacent corners of the edge of the item of laundry to be spread by the input machine to be manually entered into a clip, in particular a loading clip or spreading clip, of the input machine at the end of the at least one intermediate store or sorting store. It is also conceivable to manually enter both adjacent corners of the edge in two brackets, in particular loading or spreading brackets, of the input machine.
  • the brackets, in particular spreading brackets can be separate, independently movable brackets, but also, and in particular loading brackets, coherent brackets designed in the manner of a double bracket.
  • the manual input especially of both adjacent corners of the edge to be spread into the input machine has the advantage that the corners can be precisely aligned and can be entered in the brackets at the outermost points, which affects the quality of the further processing of the laundry item, in particular the lack quality of the laundry items Improved comparison to automatic entry or transfer.
  • the respective item of laundry is manually entered into the input machine using the first corner provided by the separator and the second corner of the edge.
  • an input of the adjacent corners of an edge to be spread by the input machine in brackets of the input machine is ensured in the shortest possible way.
  • the operator's automatic separator removes the difficult and arduous task of finding and pulling out a first corner of the item of laundry to the laundry pile.
  • the separator makes it easier for the operator to find and grasp the second corner hanging from the first corner.
  • Another advantageous possibility for designing the method provides for the laundry item held by the separator at a first corner and thus made available to be automatically taken over from the separator or from the separator with this corner to hand over.
  • the separator automatically transfers and / or accepts the first corner of the laundry item to a clip of the at least one intermediate store, the at least one sorting store or an identification device.
  • the respective item of laundry automatically reaches the at least one intermediate store, at least one sorting store or the at least one identification device from the separator.
  • the at least one sorting store or the at least one identification device After the automatic transfer of the transfer of the first corner of the item of laundry from a clip or to a clip of the at least one intermediate store, the at least one sorting store or the at least one identification device, the second corner of the edge, preferably the edge to be stretched out by the input machine, of the item of laundry is preferred manually determined and entered in a parenthesis. It can also be a bracket of the intermediate store, sorting store or the identification device. With this procedure, a partially automatic transfer of brackets is provided, whereby the separator automatically transfers the first corner, but transfers the second corner manually.
  • This mixed automatic and manual clamp and / or corner transfer is particularly suitable for large items of laundry, in which the search and detection of the second corner of the item of laundry hanging down deeply from the separator would require a great deal of equipment and time and, above all, would be too imprecise could.
  • the method can also be designed such that the respective item of laundry with both adjacent corners of the edge to be spread by the input machine is automatically transferred from the at least one intermediate store or at least one sorting store to the input machine, preferably to loading clips or spreading clips thereof.
  • the separation of the laundry items and the transfer of at least one corner thereof to the respective brackets of the input machine are automated. Manual steps can take place between the separation and the transfer to the input machine, in particular the attachment of at least the second corner of the separated item of laundry into a corresponding clip of the intermediate store and / or the sorting store.
  • Steps or transfers that are easy to automate are carried out automatically, while, in particular for large items of laundry such as bed sheets, in particular king-size bed sheets, tablecloths or bed covers, the steps or transfers that are complicated or only to be carried out automatically inaccurately are carried out manually.
  • the method is provided to visually check and if necessary correct the seat and / or position of the at least one corner of the respective item of laundry automatically entered into a bracket by a person or imaging device. This makes it possible, despite the automatic input and / or transfer of at least one corner in one bracket or from one bracket to the other to intervene, if necessary, if this should be necessary due to the high quality requirements in the lack or finish quality of the laundry items.
