Definitions

  • the invention relates to methods for feeding items of laundry to a laundry treatment device, preferably a lack, according to the preamble of claim 1, 13 and 17.
  • the invention further relates to devices for feeding laundry items to a laundry treatment device, preferably a defect, according to the preamble of Claim 5, 9, 11, 15 and 19, respectively.
  • Laundry items are supplied to laundry treatment equipment such as mangles with devices commonly referred to as input machines.
  • transverse edges which are also referred to below as the front edge or the rear edge, run transversely to the feed direction.
  • the spreading device has spreading clamps which can be moved transversely to the feed direction and which hold adjacent corners of a transverse edge, in particular a front transverse edge, and extend or spread this transverse edge by moving apart.
  • the laundry is still spread by the Spreizeinrichtgung.
  • a disadvantage of the known input machines is a relatively large travel of the Sp Dr Drklammern of external loading stations. It is also disadvantageous in known input machines that the items of laundry placed on the respective loading station with a central or near-center portion of each front transverse edge can slipping uncontrollably from lay-up areas of the loading stations. The same applies to the extended transverse edge region of the item of laundry laid down by the expansion clamps on a front region of the supply conveyor. Finally, the loading stations which are arranged in a stationary manner in front of the spreading device in the case of known input machines can have an ergonomically unfavorable effect on the application of areas of the items of laundry to their place of placement even when mangles are growing.
  • the invention has for its object to provide a method and apparatus for supplying laundry items to a laundry treatment device, in particular a defect, which ensure a high treatment performance and a reliable and ergonomic operation.
  • a method for achieving this object comprises the measures of claim 1.
  • This method provides that laundry items are transferred from external loading stations with a reduced distance with respect to the outer loading stations to the center of the feed conveyor to the expansion clamps. This shortens the travel of the expansion clamps after the acquisition of the respective laundry item. This leads to shorter cycle times.
  • the transfer of laundry items from a central loading station to the spreader is not hindered by the transfer of the laundry items with a reduced distance to the center of the feed conveyor.
  • the Sp Dr Dr.mmern for accepting the respective item of laundry have a relation to the outer Beladestationen reduced distance to the center of the feed conveyor, said distance to the center of the feed conveyor corresponds to at least half the distance between the two expansion of a Sp Dr.mmercrus. At this half distance then the directed towards the center of the feed conveyor Sp Drklammer the Sp Drklammercrus is removed from the center of the feed conveyor.
  • expansion clips which take over laundry items from off-center loading stations do not disturb the transfer of items of laundry from a middle loading station.
  • An advantageous development of the method provides that the items of laundry are transferred from or to the respective loading station to a movable transfer bracket pair that moves the laundry to the respective, in particular next, Sp Dr.mmerschreib. At the end position of the pair of transfer staples, the respective item of laundry is then transferred to a pair of spreader clips.
  • the respective pair of transfer staples can thus transfer the respective item of laundry from the off-center loading station to a pair of spreading clips which are provided near and / or next to the center of the supply conveyor.
  • a further possibility of the advantageous embodiment of the method is to move the transfer clamps outboard loading stations in end positions that are less far from the center of the feed conveyor than the relevant external loading station.
  • the distance is between the center of a transfer bracket pair to the center of the feed conveyor 1-11 ⁇ 2 times the distance of the transfer staples of the transfer staple pair.
  • transfer clamps of outboard loading stations are movable on oblique rails toward the center of the feed conveyor, with the rails of the outboard loading station terminating at a distance adjacent the center of the feed conveyor.
  • the outer transfer clamps for transferring laundry items to the expansion clamps can be moved close to the center of the feed conveyor.
  • the transfer brackets of outboard loading stations are moved to the center of the infeed conveyor only so far that they do not hinder the transfer of such items of laundry originating from the central loading station.
  • the rails arranged downstream of the outer loading stations run obliquely in the direction of travel of the pairs of transfer brackets in the direction of the feed conveyor, preferably to the center of the same and / or inclinedly rising.
  • the items of laundry are thereby not moved transversely to the feed direction by the pairs of transfer staples, but also in the feed direction to the spreading device spaced apart from the loading station and optionally or alternatively also lifted in order to be able to transfer areally larger items of laundry to the supply conveyor.
  • the outer loading stations associated rails with a certain length. This length is chosen so that the transfer bracket pairs of the outer loading stations associated rails for transfer of laundry items to the expansion brackets so far to the expansion brackets are so far that when passing the laundry items to the expansion brackets the centers of the transfer bracket pairs only to the 1- to 11 ⁇ 2 -fold distance of the respective transfer bracket pair from the center of the feed conveyor are removed. This also allows the laundry load to be transferred from the central loading station to a central pair of spreader clips, regardless of items of laundry that originate from the outer loading stations.
  • each loading station has a narrow loading conveyor with at least one circulating conveyor belt guided between deflection drums and a support means carrying the deflection drums.

  • the respective transfer bracket pair 21 passes on the oblique rail 23 and the rear end 26 thereof. This end 26 of the rail 23 is located above and in the feed direction 10 to the spreader 12 towards the lower end thereof.
  • the rail 23 is obliquely directed in three-dimensional space, and indeed as well as the rail 24 of the left loading station 11, which, however, is mirror-inverted to the rail 23.
  • the upper, rear end 26 of the rail terminates at a distance from the end 25 of the middle rail 22. Therefore, the pair of transfer brackets 21 moved to the end 26 of the rail 23 are spaced apart from the vertical longitudinal center plane of the input machine. At this off-center location, the laundry item is transferred from the transfer clamps 20 of the transfer bracket pair 21 to the already trailing, waiting or later behind the transfer bracket pair 21 spread clamps 14 of a pair of expansion clamps closest to the transfer point ( Fig. 10 and 11 ).
  • the expansion clamps 14 are moved apart to stretch the front transverse edge of the garment.
  • the (left) expansion clamp 14 located at a distance next to the vertical longitudinal center plane of the device lays a greater distance than the other (right) expansion clamp 14 of the spreader clip pair holding the laundry article further from the longitudinal center plane.
  • the expansion clamp 14, which lies closer to the vertical longitudinal center plane has to travel through the longitudinal center plane in order to extend the front transverse edge of the item of laundry and to spread out the item of laundry.
  • the transfer bracket pairs 21 on each of the rails 22, 23 and 24 and the expansion brackets 14 of the spreader 12 lie in two different parallel planes (FIG. Fig. 11 ). However, these levels are as close together as possible, so that the expansion clamps 14 can pass the transfer brackets 20 and their slides, but the transfer of the corners of the respective laundry from Transferklammercru 21 to the Sp Dr Drklammern 14 is reliably possible. Due to the fact that the transfer clamps 20 can run along the expansion clamps 14, it is possible that several or even all pairs of transfer clamps 21 are located at the upper end 25, 26 of the respective rail 22, 23 or 24 without colliding thereby ( Fig. 12 ).
  • the expansion brackets 14, both empty expansion brackets 14 as well as laundry carrying expansion clips 14, on the transverse rail of the spreader 12 behind the transfer bracket pairs 21 pass unhindered.
  • the spreader 12 and the transfer bracket pairs 21 are pivotally mounted on a frame of the input machine.
  • the loading stations 11 together with the spreader 12 and the transfer bracket pairs 21 are pivoted up into a in the Fig. 2
  • the loading station 11, the spreader 12 and the transfer bracket pairs 21 with their associated rails 13, 22, 23, 24 mounted on a pivoting device 59.
  • the in the Fig. 1 and 2 shown pivoting device 59 has in the region of opposite longitudinal edges or sides of the feed conveyor 17 via one in the present case L-shaped rocker 60.
  • the two opposing rockers 60 are pivotable at a free end about a rotation axis 61 on opposite side walls 62 of the frame of the input machine stored.
  • the two opposite longitudinal edges of the feed conveyor 17 associated swing 60 of the pivoting device 59 are connected by transversely to the feed direction 10 extending cross member 63 to a three-dimensional frame structure with each other.
  • This framework also serves to fix the rails 13 of the spreader 12, the rails 22, 23, 24 of the transfer bracket pairs 21 and optionally also the loading station 11 on the pivoting device 59th
  • the loading station 11, the spreader 12 and the transfer bracket pairs 21 are pivoted by the pivoting device 59 in an inoperative position, that then at least one operator, the front end 16 of the feed conveyor 17 is freely accessible, for example, manually to grow one of the input machine downstream defect Serving oilcloths on the front of the feed conveyor 17 hang.
  • the loading station 11, the spreader 12 and the transfer bracket pairs 21 again in their in the Fig. 1 swung back operating position shown.
