Definitions

  • the invention relates to a machine for folding laundry items along a desired line, with a switchable infeed conveyor, a folding device assigned to the infeed conveyor and a further conveying device, which under the control of edge sensors on the infeed conveyor lie laundry items with a movement transverse to the longitudinal direction of the infeed conveyor to the folding device promotes.
  • Folding "along a desired line” means a center fold, a third fold or a quarter fold of the laundry items. In the majority of cases, a center fold occurs, in which a piece of laundry is folded along a center line. Folding machines of the type mentioned in the introduction are therefore usually referred to as folding machines working with intermediation. This term is used in the description below, but it is to be understood that this term generally means folding along a desired line.
  • Folding machines of the type mentioned in the introduction are usually arranged behind longitudinal folding machines in order to subject the items of laundry which have been longitudinally folded in the longitudinal folding machine at the end to at least one transverse folding. Folding machines of the type mentioned in the introduction are therefore often referred to as cross-flattening machines.
  • the known transverse folding machines usually have a width which corresponds to the width of the longitudinal folding machine.
  • one or more longitudinal folds can be carried out on a piece of laundry in the longitudinal folding machine, while at least one transverse folding along a desired line, that is to say a transverse folding with switching, can be carried out in the downstream transverse folding machine.
  • the machine known from DE-PS-1 785 577 has in the middle of the infeed conveyor a further conveying device in the form of pairs of rollers which convey a piece of laundry that has run in under the control of edge sensors transversely to the extension of the longitudinal conveyor inwards and downwards, where then folding is performed using a folding sword. It can be seen that in this known machine there is precisely the disadvantage explained above that, for example, when small items of laundry arrive in three or four lanes on the infeed conveyor, transverse folding is no longer possible, unless by hand.
  • the present invention aims to provide an improvement in order to be able to carry out a very precise final transverse folding, particularly on small items of laundry.
  • this is achieved in that the folding device is arranged in the region of a longitudinal side edge of the infeed conveyor.
  • a folding machine according to the invention requires only comparatively little space in the width direction, so that a folding machine according to the invention can be provided behind a conventional longitudinal folding machine of greater width for each web along which small items of laundry are placed and longitudinally folded. If, for example, small items of laundry are to be treated on three webs, each with a width of one meter, on a longitudinal folding machine with a width of three meters, three transverse folding machines are arranged downstream of the longitudinal folding machine when the present invention is used.
  • a folding machine has an infeed conveyor 1, which is arranged on an appropriate frame and is arranged downstream of a laundry treatment machine, for example a longitudinal folding machine.
  • the laundry items pass from the upstream laundry treatment machine to the infeed conveyor 1 via a conveyor 2.
  • the infeed conveyor 1 is switchable and it is always switched off when a laundry item lies on it, and is switched on again when the laundry item is from him is deducted, as explained below.
  • the infeed conveyor 1 can be a conventional belt conveyor which runs around a front roller 3 and a rear roller 4.
  • the direction of movement of the belts of the infeed conveyor 1 and the feed conveyor 2 is shown in FIG. 1 with an arrow.
  • the surface of the belts of the infeed conveyor 1 is preferably such that there is only slight friction between the infeed conveyor and the items of laundry.
  • FIG. 2 is a front view of the preferred embodiment, as seen from the right according to FIG. 1.
  • a further conveying device 6 is arranged above the right side of the infeed conveyor 1 according to FIG.
  • this further conveyor 6 comprises an endless belt conveyor 7, the belts 8 of which run around a front roller 9 and a rear roller 10.
  • a frame (not shown) carrying the rollers 9, 10 and thus the belts 8 is articulated via two links 11 and 12 to a frame, also indicated only schematically, so that the belt conveyor 7, 8, 9 from the one shown in FIG. 2 with a broken line Position at a distance above the infeed conveyor 1 in the position shown in Figure 2 with a solid line in contact with the upper surface of the infeed conveyor 1 and vice versa can be moved by pivoting.
  • a preferably pneumatic piston-cylinder device 13 is provided for causing these movements of the belt conveyor 9, which, in an appropriate manner, with the frame or frame carrying the belt conveyor 7 or with one of the links 11 or 12 and a stationary part of the Folding machine is connected.
  • a piston-cylinder device 13 can expediently be provided on each side of the belt conveyor 7. When the piston rod is pushed out, the belt conveyor 7 moves from the position shown with the broken line to the position shown with the solid line, and vice versa.
  • roller 9 To drive the belt conveyor 7, one of its rollers, here the roller 9, is connected to a drive belt 14 which also runs over a pulley which is arranged at the articulation point of the link 11, which is coupled to the roller 9. At this point, a further pulley is provided, over which a belt 15 runs, which continues to run over a further pulley, which is arranged on the output shaft of a drive motor 16, which is appropriately provided on the machine frame, not shown.
  • the belts 5 of the infeed conveyor 1 can all have a width as indicated on the left-hand side according to FIG. However, for the intended function of the machine it is advantageous if in the area of the belt conveyor 7 the infeed conveyor 1 has a uniform belt band, the width of which corresponds approximately to the length of the belt conveyor 7 shown in FIG. Such an embodiment is not shown.
  • the infeed conveyor 1 has in the region of the belt conveyor 7 a wider belt band 5a, the width of which corresponds to approximately half the length of the belt conveyor 7.
  • a table surface 5b On the right side of the webbing 5a according to FIG. 2 there is a table surface 5b, which can be made of plastic, metal or the like, provided that it has a smooth surface.
  • This table surface 5b is bent downward at its right end according to FIG. 2, as is indicated in FIG. 2 by the dashed line.
  • the surface of the table surface 5b lies approximately in the plane of the upper runs of the belts 5 and 5a.
  • a folding station which has two cooperating folding conveyors 17 and 18 and an associated folding sword 19.
  • the direction of movement of the folding conveyor is indicated by arrows and it runs from right to left on their mutually facing runs according to FIG.
  • the folding station 17, 18, 19 is assigned various components which serve to place the item of laundry emerging from the folding station 17, 18, 19 on a further conveyor, which can be a stacking conveyor known per se, for example.
  • a further conveyor which can be a stacking conveyor known per se, for example.
  • the details of these components are not part of the invention, so that they are not explained.
  • An incoming piece of laundry is delivered from the feed conveyor 2 to the infeed conveyor 1 running at this time.
  • the infeed conveyor 1 is stopped.
  • the belt conveyor 7 is in the position shown in FIG. 1 at a distance above the infeed conveyor 1.
  • the belt conveyor 7 is removed from that in FIG 1 shown position brought into the position shown in Figure 2 with a solid line in contact with the infeed conveyor 1 or pivoted.
  • the belt conveyor 7 is already driven at this point in time, so that the laundry item is drawn off from the infeed conveyor 1 according to FIG.
  • the folding sword 19 is then actuated at the point in time which was determined in a direction transverse to the conveying direction of the infeed conveyor 1 as a function of the previously determined dimension of the item of laundry.
  • the folding sword 19 pushes the laundry item along the desired line into the gap between the folding conveyors 17 and 18, which perform the folding as a result of their drive and then deliver the laundry item to the downstream components and the like.
  • the surface of the belts 8 is expedient to form the surface of the belts 8 from a material which has a comparatively high coefficient of friction compared to the laundry. This ensures safe removal of the items of laundry in the transverse direction since the belts 5 and 5a have a surface made of a material with a relatively low coefficient of friction, and because the table surface 5b is made of a material with a smooth surface over which the item of laundry slides easily.
  • a machine according to the invention has a comparatively small width, so that when working in conventional longitudinal folding machines with a plurality of webs, a folding machine according to the invention can be provided for each web, yet folding along a desired line, i.e. folding with Mediation can take place, as was previously not possible for small items of laundry.
  • a guide plate can be provided, by which it is ensured that the removed laundry items run correctly to the folding station 17, 18, 19.
  • endless belt conveyor 7 can be driven intermittently or continuously.
  • a folding station with a folding sword 19 instead of a folding station with a folding sword 19, a folding station with an air jet device can also be provided.
