Definitions

  • ABSTRACT A device at the discharge end of a rotating drum, e.g. in a washing machine, through which elongated, flexible objects such as bed sheets are transported, for pre venting the discharged objects from being twisted or turned when placed on a conveyor lband located below the drum.
  • the drum is, at the discharge end, provided with projecting members designed to lift momentarily a discharged portion of anobject from the conveyor band during the rotation of the drum.
  • the present invention relates to a discharging device on a rotatable drum and more specifically to a device on a rotatable drum, through which elongated, flexible objects can be transported, e.g. bed sheets or overalls in connection with washing or drying, for preventing discharged objects from the drum to be twisted or turned when placed on a transport member located below the drum, e.g. a conveyor. If the objects are twisted or turned, the further treatment of the objects will be more complicated.
  • the turning of the elongated objects to be washed occurs due to the fact that one end of the objects falls down on to the conveyor and remains there, while the other end of the object is still located in the rotating tube or the rotating drum and, consequently, is provided with a rotary movement relative to the end located on the conveyor.
  • One way to avoid this disadvantage is to place the conveyor at such a large distance below the discharging end of the tube or the drum that the end of the object first discharged will not reach the conveyor, until the complete object has been discharged from the tube or the drum. Since the objects may be very long, e.g. 3 meters or more, however, it is highly impractible to place the conveyor at such a large distance below the discharging aperture.
  • the object of the present invention is to eliminate or, at least, substantially reduce the turning and twisting of the objects during the discharge from the tube, or the drum. This object is attained by the device according to the invention having the features as defined in claim 1.
  • the device according to the invention has theadvantage that the conveyor can be placed relatively close to the discharging aperture and that still the twisting and turning of the objects discharged during the discharge operation is eliminated or in any case considerably reduced so that the continued treatment of the objects is substantially simplified.
  • FIG. ll shows a rear view of a washing drum adapted for rotation
  • FIG. 2 shows the rear portion of the washing drum of FIG. 1 in a side-view.
  • the washing drum illustrated in FIG. 1 comprises a tube 10, which is adapted to be rotated in either direc tion around its longitudinal axis and which is, at its internal surface, provided with axially extending ribs 1 ll. These ribs are adapted to facilitate the tossing around of the objects within the drum and are secured in a convenient manner at outwardly bent edges 10a on the internal periphery of the tube.
  • FIG. 2 illustrates the rear portion of the tube 10 with the ribs 11 projecting a certain distance from the end of the tube.
  • the ribs at their radially external edges present an area 12, which is inclined rearwardly towards the axis of the tube. This inclined area 12 prevents the elongated objects, which are discharged from the tube, from being wound around the projecting portions of the ribs during the rotation of the tube.
  • the projecting rib ends at the discharged end of the tube can, of course, be designed in many differentways within the scope of the invention. lE.g., it is not necessary that the projecting rib ends are long, also comparatively short projections can be used if properlyv designed. Further, it is not necessary that the ribs located in the tube are utilized as carrying members. The same result may, of course, be achieved by means of separate members, which re secured at convenient positions adjacent the discharge end of the tube, either immediately inside said apertureor else outside thereof and then at least partly projecting beyond the aperture.
  • the design of the projecting portions in order to facilitate the sliding offof the objects during the rotation of the tube can, of course, also be carried out in many different ways.
  • a device as claimed in claim 1 characterized in that the carrying members consist of ribs (11), which are arranged at the internal wall of the rotating drum 3.
