Definitions

  • the invention relates to a laundry device for treating textile ware, such as laundry, mainly comprising a housing having a lower opening closable by a door, a drum assembly disposed within said housing and comprising opposed perforate drum sections, a horizontal shaft and guide means for slidably supporting a drum section axially through said lower opening.
  • drum machines of the kind set forth are known in many embodiments for domestic and industrial use.
  • the invention relates in particular to machines of the industrial type, which can deal with comparatively large quantities of textile ware, such as is disclosed in US-A-2,817,501.
  • the industrial machines constitute part of a whole process for treating textiles and one of the problems involved is the supply and delivery of the quantity of textiles in the machine or the drum respectively. It is known from US-A-2,817,501 in a laundry machine to slip out a section through an opening in the housing for introducing or removing the textiles. In this machine the drum is not divided into compartments so that the delivery of washings cannot be automaticated. Moreover, high speeds for centrifuging cannot be obtained.
  • the invention has for its object to improve a device of the kind set forth to an extent such that the above mentioned drawbacks are obviated.
  • the device according to the invention is distinguished in that said shaft is provided with a wing-like carrier having said guide means for - slidably supporting each drum section and for isolating said drum sections from each other whereby each drum section forms with the wing-like carrier a separate compartment for containing laundry, whereas said housing is also provided with an upper opening closable by a door, so that any drum section may be filled by sliding a section through said lower opening and emptied by sliding a section through said upper opening.
  • the use of a carrier fastened to the shaft has the advantage that a very robust construction is obtained, which can resist very high rotary speeds as occur in centrifuging.
  • the carrier provides furthermore the advantage that the drum can be easily divided into two or more compartments so that washings of different kinds can be simultaneously washed. Moreover, one of the compartments can now be disposed so that, when it is slid out, the washings automatically drop out of the compartment.
  • a stable slide guide is ensured by arranging the guide for each drum section along the end rims of the drum jacket.
  • the guide is preferably provided with a roller element for reducing frictional resistance.
  • a synthetic resin lining may be provided as an alternative. This lining provides, in addition, an improved distribution of forces.
  • tensioning means are provided to clamp each drum section.
  • These tensioning means are preferably formed by an inflatable body by which each drum section is moved away from the wing carrier.
  • each door for closing the inlet or outlet opening respectively of the housing is slidably guided parallel to the rotary shaft of the drum, the door being provided with means for coupling with a drum section. In this way the weight of the drum and the textiles contained therein is partly absorbed by the guide of the drum itself and partly by the guide of the door.
  • each door is constructed in the form of a swing door, whilst the drive for sliding the drum forward is formed by a cylinder engaging the roller or sliding element between the drum sections.
  • the device shown in Figures 1 to 4 mainly comprises a closed housing 1, in which a drum 3 is rotatably driven around a horizontal shaft 2. To this end the shaft 2 is prolonged on the right-hand side in Figure 1 to beyond the housing 1, on which prolongation a pulley of a rope transmission 4 is fastened.
  • the rope transmission 4 is driven by a motor 5 (not further described) which is disposed on top of the housing 1.
  • the housing 1 is provided on one side with a door 5 for introducing the textiles and on the other side with a door 6 located at a higher level for delivering the textiles.
  • the operation of the doors will be described more fully hereinafter.
  • the two doors 5 and 6 are provided with sealing means such that in the closed state the housing 1 may contain a detergent across which the drum 3 is rotated.
  • the drum is divided into sections and in the embodiment shown every two diametrically opposite, identical sections 7 (see Figure 2) can be slid out of the openings 5 and 6 respectively.
  • Each drum section comprises a circular jacket wall 8 connected on the head side with two end walls 9.
  • the shaft 2 is provided with two diametrically opposite wings 10 consisting of a hollow construction (see Figure 3), the axial length of which corresponds with that of each drum section 7 and the radial length of which corresponds to the distance between the end rims of the jacket surface 8.
  • the drum sections 7 are slidably connected in an axial sense with the wings 10 by means of a sliding guide 11 shown in detail in the sectional view of Figure 3.
  • the sliding guide comprises two T-shaped, thickened longitudinal strips 12 connected with the wing 10 and the drum section 7 respectively, about which grips a U-shaped intermediate piece 13 on the outer and inner sides of the drum. Between the U-shaped parts rollers 14 are arranged to roll along the head side of the T-shaped strip part 12. Such a roller guide reduces considerably the frictional resistance.
  • the intermediate piece 11 will each time slide along over half the distance (see Figures 2 and 4).
  • the intermediate piece 11 is provided on both sides with a freely rotatable roller along which a cable is passed. Each cable is fastened at one end to the displaceable drum section 7 and at the other end to the wing 10.
  • the wall 15 is guided in a U-shaped guide 17 secured to the wing 10.
  • a protective wall 18 of the drum section 7. Between the upper flange of the guide 17 and the wall 15, which can move up and down, extends the flange of a protective wall 18 of the drum section 7. The arrangement is such that an axial displacement of the drum section 7 is ensured whilst nevertheless adequate protection of the sliding guide 11 with respect to the textiles contained in the drum section 7 is obtained.
  • a head wall 9 of each drum section is provided with coupling means for connecting the door 5 and 6 respectively with the head wall 9.
  • the coupling means shown are formed by two brackets 20 into which can grip a latch 21.
  • the latch is connected with a lever 22 pivotably connected with the inner side of the door, a pneumatic ram 23 being arranged between every two of them.
  • the door itself is supported by a telescopic sliding guide 24 of a size such that high bending stress in a vertical sense can be absorbed.
  • the telescopic sliding guide 24 comprises a pneumatic ram 25, by which the door can be moved into the open and closed positions.
  • a synchronous mechanism ensures a smooth opening and closing of the telescopic guide 24 on both sides of the door.
  • a pinion 28 journalled in a telescopic part rolls along a toothed rack connected with the door.
  • a torsional rod 26 rotatably journalled in the door is provided on both sides with a pinion rigidly secured thereto, along which is passed a chain which drives the pinion 28.
  • the construction for the upper door 6 is the same as for the door 5 on the rear side of the device in Figure 2. This door is also connected by corresponding coupling means with the head wall 9 of each drum section 7.
  • the device described above operates as follows.
  • the ram 25 is energized in the reverse sense so that the door slides inwards, carrying along the drum section 7. Subsequently, the inflatable body 16 can be charged with a pressure medium so that the wall 15 is urged downwards until the T-shaped ends of the end strips 12 are firmly clamped in the U-shaped elements 13 of the intermediate element. Thus a firm connection is established between the drum section 7 and the hollow wing 10.
  • the drum After disengagement of the latches 21 from the brackets 20 the drum can be turned through 180°, as a result of which the upper, empty drum section turns into the lowermost position, after which the cycle described above can be repeated.
  • the motor 5 rotates in a conventional manner via the rope transmission 4the drum with the desired speed.
  • the drum can be emptied, for which purpose first the hollow wing 10 is turned into a horizontal position so that the upper drum section with the brackets 20 fastened thereto and the other head wall are located at the latches 21 of the coupling means in the door 6.
  • the inflatable body 16 is discharged, sufficient play is formed in the sliding guide 11.
  • the ram 25 associated with the door 6 is energized, this door is pushed outwards, carrying along the upper drum section.
  • the textiles of this section are urged over and across the wall 15 by the rear head wall 9 and along the horizontal guide plate 31 the goods arrive at the delivery conveyor 32 (see Figure 1).
  • the second drum section can be emptied in a similar manner after the drum is turned through 180°.
  • the drum sections can be very readily filled and emptied, whilst large amounts of textiles can be simultaneously treated.
  • the device may, in addition, be used as a "hygienic" treating device by disposing it at the height of a wall 33 (see Figure 1) so that the supply is separated from the delivery.
  • a wall 33 see Figure 1
  • FIGS 5 to 8 show an alternative embodiment of the washing device in accordance with the invention.
  • the doors closing the openings of the housing 1 are constructed herein as swing doors 51 adapted to turn outwardly around the hinge 50.
  • the outward swing of each door is performed by means of pneumatic rams 52, which are arranged in the housing 1 and the connecting rods of which engage a bracket 53 fastened to the door 51.
  • the sliding guide comprises a H-shaped piece provided on the inner side with nylon lining 55, which accommodate the T-shaped ends 12 of the drum sections.
  • the intermediate rollers are failing here and guiding is fully performed by the synthetic resin lining 55.
  • This lining has the advantage that the load is evenly distributed along the full length of the T-shaped end parts 12 and respectively the flanges of the H-shaped intermediate piece 11 so that this construction can hold very heavy loads as occurring, for example, in the centrifuging phase of the machine, in which forces of 300 gs (gravity) have to be taken into account.
  • the T-shaped elements 12 are at right angles to the top wall of the carrier 10, in contrast to the inclined position of the wall in Figure 3.
  • the inflatable body 16 is arranged here between two salient parts 56 of the closing plates 15 of the drum section.
  • the closing plates 15 are drawn to one another in the rest position by springs 57 so that, when the drum section is slid out, they are released from the rim of the section and do not produce frictional resistance.
  • the inflatable body 16 has the same function as in the preceding embodiment and via the plates 15 it will urge the whole drum section upwards so thattheT-shaped end pieces 12 are firmly pressed against the flanges of the intermediate piece 11. Therefore, during the washing run the whole drum remains a rigid unit. It will be obvious that this construction guarantees a uniform load of the drum sections so that the inflatable body 16 can be replaced in a simple manner.
  • each section can be slid outwards by means of a pneumatic ram 60 located on the outer side of the housing 1 (see Figures 6 and 7).
  • a pneumatic ram 60 is provided at both ends of the housing 1 and each of them engages an intermediate piece 11 by means of the cam 61 which falls in between two cams 62 of the intermediate piece 11. From Figure 7 it will be apparent that when the piston rod 63 of the ram 60 is slid to the right the right-hand cam 62 engages the cam 61 of the piston rod so that the intermediate piece 11 is shifted to the right in Figure 7. Upon withdrawal the left-hand cam 62' is engaged and the intermediate piece is returned to the initial position.
  • the piston 64 on the piston rod 63 can thus occupy the extreme left-hand position in the ram 60, whilst the intermediate piece 11 gets into the correct position centrally between the drum sections.
  • the auxiliary ram 65 which is arranged coaxially with the main ram 60 will urge, when charged, the piston 64 over a predetermined distance to the right into the zero position so that the cam 61 gets exactly in between the cam 62 and the cam 62' so that it remains free thereof.
  • the drum can be rotated without the cams 62 coming into contact with the cam 61.
  • a cable system like that of the preceding embodiment is arranged for each intermediate piece 11 so that the systems on both sides of each drum section are interconnected (see Figure 8).
  • One cable 80 is connected with the cable 80' on the other side of the drum section 7, whereas the cable 81 is connected with the cable 81'.
  • This is obtained by means of a cable part which is freely displaceable via guide wheels 82 at the corners of the drum section along a head end of the drum section 7.
  • This driving system has the advantage that the rams 60 on both sides of the drum section 7 can arbitrarily move relatively to one another.
