Definitions

  • the invention relates to an apparatus for sorting identifiable items, for example laundry or similar items, and as further described in the introduction to claim 1.
  • a number of different apparatuses for sorting laundry are known and for sorting the laundry prior to as well as after the washing.
  • the clothes are often provided with an identification tag such as an electronic transponder, which is permanently arranged in the clothes and which may therefore be used for controlling sorting processes etc. prior to as well as after washing of the clothes.
  • a known sorting apparatus applies compressed air in connection with the sorting of the clothes in that the compressed air is used for pushing the clothes off the conveyor at the point of destination.
  • This system is disadvantageous when sorting clothes prior to the washing because impurities and the like from the clothes are stirred up. Moreover, such sorting systems make a lot of noise.
  • Another known apparatus is based on transferring individually conveyed clothes items on a conveyor belt to one of two destinations by moving or displacing the conveyor. This results in a relatively slow, low-capacity apparatus since it takes relatively long time to move the conveyor, or one end thereof, due to its weight.
  • the sorting apparatus and with the features disclosed in the characterising part of claim 1 is advantageous in that the rearrangement of the sorting units following a choice of destination takes place very quickly and at a low energy consumption because only few mechanical parts require rearrangement. Furthermore, the items are mainly simply moved forward in a steady but quick movement so that no unnecessary stir of any impurities from the clothes during the sorting will occur.
  • the invention is particularly developped for sorting laundry where each piece of laundry has a transponder for identification for which reason the invention is now explained in connection with the sorting of laundry, but it is obvious to a person skilled in the art that also other identification methods are applicable, e.g. bar codes, colour or colour codes, pattern recognition etc. Furthermore, it is obvious to a person skilled in the art that also other items than laundry may be sorted with the apparatus according to the invention, for example newspapers, consignments, foodstuffs, parcels, spare parts of any kind, semi-manufactures etc.
  • Each item will usually be provided with an identification tag, for example a transponder, which is read.
  • the read data are used for controlling the sorting apparatus which is adapted in such a manner that the position and size of each item are recorded and form part of the control.
  • the invention also relates to an independent sorting unit for use in sorting apparatuses, and as disclosed in the characterising part of claim 9 or claim 10.
  • sorting units and a number of conveyor belts it is possible to build up a sorting apparatus.
  • a number of different conveyors or conveyor belts may be used if merely they can convey the clothes items at an adequate speed.
  • sorting unit according to the invention it is therefore possible to build up a sorting apparatus of any size and thus cover almost any sorting requirement for laundry and similar items which are placed individually and freely on a conveyor.
  • Fig. 1 shows a sorting apparatus for laundry comprising a feeding conveyor A, a reading conveyor B, an intermediate conveyor C and a sorting section D with three sorting conveyors 2 and three sorting units 1 mounted on a common longitudinal supporting profile 17 which is carried by a number of columns 19 standing on a base 20, e.g. a floor.
  • the apparatus is adapted for sorting laundry which individually and spaced apart is placed on the feeding conveyor A at position E.
  • the laundry is placed manually or mechanically on the feeding conveyor and with an equal space of at least 50-60 cm between each clothes item.
  • the laundry is sorted in the apparatus in the following manner: Clothes items are individually conveyed from the feeding conveyor A to the reading conveyor B where an antenna 21 is placed below the belt for reading transponders fixed in or on the clothes. To ensure a suitably close contact between each transponder and the antenna 21, there is arranged a quide plate 22 above the conveyor and this guide plate will prevent the clothes or parts thereof from passing the antenna at too great a distance. Then the items are conveyed to the intermediate conveyor C from where they are further conveyed to the sorting section D and sorted out into the distinations 5.
  • the entire sorting process is controlled by an electronic control unit comprising a programmable unit, such as a PLC, which receives a number of data from the sorting apparatus.
  • the conveyor A comprises a revolution counter 23, and the conveyor B comprises likewise a revolution counter 23', said revolution counters being socalled encoders, and each sorting conveyor 2 in the sorting section D similarly has a revolution counter 23'' in the form of an encoder.
  • a photo cell which partly registers that a clothes item is on its way and partly triggers the antenna 21 so that it is ready for reading the transponder in the clothes.
  • the photo cell arrangement 24 measures the length of the clothes item in the travelling direction.
  • At the end of the intermediate conveyor C there is also arranged a photo cell arrangement 24' and on each conveyor 2 there is likewise arranged a photo cell arrangement 24'' in that these photo cell arrangements are used for readjusting the sorting apparatus in case a clothes item has been displaced, for example due to slip or compression, so that the control circuit of the sorting apparatus will always have correct information on the individual clothes items on the conveyor, ie. where they are situated and the actual extension thereof on the conveyor.
  • the individually conveyed items in the sorting section D will be conveyed by the top end of each of the inclined conveyors 2 to a sorting unit 1 which will either allow the clothes to fall down through a shaft for a sorting destination 5 or transfer the item to the next conveyor.
  • the conveyor belts 2 are endless belts made of plastic or rubber and moved at a comparatively high rate of speed, e.g. of the order of 1 m/sec in the travelling direction which is indicated by an arrow by each conveyor.
  • the functioning of the sorting unit 1 will be explained below with reference to fig. 3.
  • By the end of the sorting apparatus there is provided a further shaft 6 such that at the end of the last sorting conveyor 2 there are two sorting destinations 5.
  • All the items which are placed on the sorting apparatus by the position E may therefore electronically be sorted out to the destinations marked 5.
  • Three sorting conveyors with three sorting units may accordingly transfer the items to four different destinations.
  • sorting apparatuses of this kind may be extended to form very big apparatuses in that there is added an additional sorting destination each time the apparatus is extended by a sorting conveyor 2 and a sorting unit 1. It is also clear from figs. 1 and 2 and the explanation thereto that the sorting section may extend at the same level as far as desired since the individual sorting conveyors 2 take an inclined upwards position in the travelling direction as shown in the drawing.
  • Each sorting conveyor 2 comprises an endless, motor-driven belt 16 extending at either end around a roller or cylinder 15.
  • Each sorting unit 1 which is arranged immediately between two conveyor ends 2 comprises in the shown embodiment two movable plates 7, 8.
  • the plates are mounted pivotably about substantially horizontal axes 13, 14 and can be manoeuvred by working cylinders 10, preferably compressed-air cylinders.
  • the plates 7, 8 are shown in two positions, one position fully drawn up and one position with a dotted line and marked 7' and 8'.
  • the sorting unit has an opening 18 so that the clothes can be freely transferred from one conveyor and down onto the next one as shown by the arrows 4.
  • One of the plates, namely the plate 7, which extends directly from one conveyor end and downwards in the travelling direction to the next conveyor end has an edge or bending 11 so that any clothes items which will stick to the belt 16 due to moisture or dirt will nevertheless be transferred to the belt of the next conveyor.
  • One end of the working cylinders 10 is secured to the frame or the like of the sorting unit 1, for example the horizontal base part 12 in such a manner that they are pivotable in their suspension point.
  • Compressed-air cylinders as working cylinders are preferably used since these may be readjusted in a few seconds, preferably in 0.2-0.3 seconds, so that even at the above-mentioned high rate of speed of the belt of the conveyors 2 it is possible to readjust the plates 7, 8 between each clothes item if so required.
  • Under the shaft 3 by the destination 5 there may be arranged a bag, a waggon or the like for collecting sorted clothes.
