Definitions

  • the invention relates to a method for separating laundry items or the like according to the preamble of claim 1. Furthermore, the invention relates to a device for Separating and / or gripping laundry items according to the Preamble of claim 7.
  • Washed items of laundry usually leave a washing machine heaped. Before they come out of a washing machine Undergo further treatments in the laundry area, for example, they are in short supply items of laundry leaving the washing machine (still damp) be isolated. The aim is to separate this Mechanize laundry or other textile items.
  • the invention is based on the object Method and device for reliable and powerful Separating and / or grasping laundry items create.
  • a procedure for solving this problem shows the measures of Claim 1 on. Because the takeover means the respective Piece of laundry transported through a gap, even heavy laundry items can be reliably pull out of the laundry pile. Above all, that also applies then when other items of laundry to be separated Items of laundry are looped around because of being carried through of the laundry through the gap relatively large Tractive forces can be transferred to the laundry.
  • the Gap also ensures that only individual items of laundry from the Takeover funds are taken over and transported on.
  • the gap during the takeover process is also proposed to use the gap during the takeover process to change in width.
  • the gripped items of laundry can be split by a gripping element be moved through.
  • the width of the gap is coupled to the item of laundry to a part of the take-over means that bounds the gap on one side.
  • This is preferably designed as a rotating conveyor, which acts on one side of the laundry. If several items of laundry have been taken, only comes the bottom item of laundry in contact with the one for coupling serving part of the takeover means making the other laundry item falls when the gripping member is raised opens at least part of the laundry.
  • a device for solving the basis of the invention Task has the features of claim 7. With that a gap which is preferably variable in size Transfer means is a takeover of individual items of laundry and safe further transport of the same is guaranteed.
  • the gap of the takeover means one that meets the requirements Friction too, which makes it possible even under difficult to separate the laundry items reliably and pull it out of the laundry heap completely.
  • Acquisition means essentially from a sponsor and one corresponding pressure element. Between in particular part of the conveyor and the pressure member is then the Gap formed. Conveyor and pressure element limit opposite one another Sides of the gap. Between the sponsor and the The respective laundry item can be moved through the pressure element. The revolving drive pulls through the gap formed in this way Conveyor the respective item of laundry. If necessary also preferably a pressure roller forming the pressure element can be driven synchronously with the conveyor. But it is also conceivable that Pressure roller to make it freely rotatable so that it can move through the laundry pulled through the gap is also moved.
  • the The width of the gap is variable.
  • the distance changeable between the conveyor and the pinch roller a corresponding movement of the conveyor or the pressure roller. If necessary, both can also be movable.
  • only the conveyor will change the width of the gap pivoted.
  • the pressure roller does not yet have one Has contact with the item of laundry, further separation takes place, if several items of laundry are gripped during the previous gripping process should have been because only the lower one (on the swiveling one Piece of laundry attached to the conveyor is coupled and the items of laundry above it from slip the (coupled) laundry item onto the conveyor.
  • the devices shown are used, in particular, from a for example, piles of laundry coming out of a washing machine automatically remove individual items of laundry 11. The on this Individual items of laundry 11 are then one Further processing in the laundry area supplied, in particular entered into a want.
