Definitions

  • the invention relates to an industrial washing machine for laundry items, which has a drum with a horizontal axis, can be loaded and emptied automatically and has loading and unloading flaps that are automatically closed and opened.
  • industrial washing machines consist of a rotatable cylinder or a rotating drum, which is attached by means of a horizontal axis inside a round basin.
  • These drums and cymbals have loading and unloading flaps for the laundry items; Some of these washing machines have these flaps on the flat side of the round drum or basin, while others have them on the cylindrical surface.
  • the washers with the flaps on the flat side tilt both the drum and the pelvis and slowly turn the drum so that the clothes fall onto the flap due to gravity; loading takes place via the same flap, but the drum is not inclined.
  • the basin unloading flap is on the side; it follows that both the drum and the basin must be installed at a certain height so that there is space for a cart in the basin that collects the washed laundry.
  • washing machines have a number of shortcomings: loading and unloading the items of laundry as well as opening and closing the flaps must be done entirely by hand; during the spin cycle it also happens very frequently that the laundry items accumulate on one side of the interior of the rotating drum and thus exert a considerable eccentric force on the axis of rotation of the drum; the wash and wash stop commands, the spin and spin stop commands as well as the rotation speed selection during washing and during spinning are carried out manually by the operator with the aid of control buttons.
  • the new washing machine consists of a perforated drum, which is located inside a cylindrical basin and is attached to a horizontal axis of rotation.
  • the cylindrical basin and drum have one or more flaps located on the cylindrical surface; more specifically, the pool has both top flaps for loading and bottom flaps for unloading.
  • baskets on one or both sides of the washing machine which are raised to the loading flap by a mechanical device and then turned over so that their contents fall into the drum inside the washing machine.
  • boats can also be used.
  • a conveyor belt or a boat is provided below the washing machine, which picks up the washed laundry items that fall out of the lower unloading flap and tilts them into a collection basket.
  • All inner and outer folding doors of the washing machine, the basin and the drum can be opened, closed and locked using mechanical, oleodynamic or pneumatic systems; these systems are controlled electronically or electromechanically.
  • the unloading flaps are closed, the loading flaps are opened and the lifting device of the baskets is set in motion, so that the items of laundry fall into the washing machine. Then the loading flaps close; Water and possibly detergent, whitening agent, fabric softener etc. flows into the washing machine. a. Solid materials that are used for washing, such as pumice or floating stone, are placed directly in the loading baskets or in the boats together with the items of clothing. When the selected washing cycle is finished, the drum is stopped, the conveyor belt starts to move and the lower unloading hatch opens so that the washed items fall out.
  • an electronic system determines whether the load of the laundry items exerts eccentric forces during rotation, which can be extremely damaging to the washing machine. If the laundry load has accumulated on one side, the electronic control system slows down and / or slows down the rotation, possibly several times, until the load is balanced during the spin cycle.
  • the baskets' loading and unloading baskets are hinged to the long edges and are opened and closed by means of hydraulic winches.
  • the loading and unloading flaps of the drum are also attached to the longitudinal edges with hinges, but they are opened and closed by a special pneumatic and mechanical system.
  • the basin flaps must be watertight and withstand the loads of the water in motion; on the flaps of the rotating drum, on the other hand, the rotational force acts during the spinning, which carries the risk that the drum edge changes and causes the flap to open. To counteract this, holes and grooves are provided on the drum flap edge at an even distance from the hinge.
  • a displaceable rod mounted on rails with teeth and pivot pins or elevations; when the flap is closed, the elevations are in the holes of the flap, while the slidable rod is pressed with the teeth against the hinge against the edge of the flap.
  • the teeth which are made in one piece with the rod, prevent the flap from opening, while the elevations located in the holes and grooves in the flap prevent the drum from expanding; threading of the flap edge from the teeth of the displaceable rod is also prevented.
  • crank lever At the same height as the hinge there is a one-piece crank lever on the flap.
  • Two rotating arms with cams which are attached to the basin by means of hinges and in accordance with the loading and unloading flap, open and close the rotating drum.
  • To open the flap of the rotating drum one has to operate the cam arm and turn the drum so that the crank lever of the flap fits into the cam of the arm; then the rod is adjusted with the teeth by means of a pneumatic piston so that the teeth align with the grooves on the edge of the flap are located. Finally the cam arms are rotated and in turn the crank lever of the drum flap also rotates so that the drum opens.
  • the washing machine can also serve as a centrifuge. It is therefore possible to provide an automatic system which consists of a series of washing machines and centrifuges, which are operated by movable baskets for loading and emptying.
  • the cylindrical basin V with a horizontal axis is held by a metal structure T by means of a pneumatic suspension S.
  • An electric motor M which is provided with a reduction gear R, causes the inner drum to rotate.
  • the basin V is equipped at the top with loading flaps P1 and at the bottom with unloading flaps P2.
  • a conveyor belt N which tilts the washed laundry items that fall out of the unloading flap P2 into a collection basket.
  • a lifting system E On the side of the basin V there is a lifting system E which lifts and tilts the loading baskets Cc so that the items to be washed fall into the interior of the rotating drum.
  • FIG. 2 shows the opening and closing mechanism of the flaps during the most important moments when opening.
  • the rotary drum 2 is provided with a flap 3, which is attached by means of a hinge on one of the long sides 4 parallel to the axis of rotation of the drum 2.
  • the flap On the hinge 4, the flap has a crank lever 5, and on the opposite edge 12 there are holes 11a and grooves 13. Opposite the flap hinge 4, on the side of the hole, there are 2 elevations 11b and a rod 10 with teeth on the drum 10a.
  • the rod 10 provided with teeth 10 is mounted parallel to the axis of rotation of the drum 2 and can be moved along the axis on rails provided for this purpose; the teeth 10a are attached to the rod so that they protrude at right angles, the distance to the drum is as large as the thickness of the flap 3 or only slightly larger.
  • Figure 3 shows a system with baskets and boats 21, 22 for loading and those (24) for unloading, with washing machines 23, connecting members 25, feeders 26 and cutters 27 of pumice or detergents, a conveyor belt 28 for loading the slingshot 34, one Conveyor 29 for the supply of pumice, a container 30 for pumice, a lifting system 31 for pumice, a metering device 32 for pumice, an addition boat 33 for pumice, centrifuges 34 and dryers 35.
