Definitions

  • the invention relates to a device for compacting compressible waste, such as cardboard, cardboard, wood waste, household waste or the like.
  • the waste is compacted by a roller rotating around it, the roller resting on the waste due to its own weight. With this arrangement, there is therefore no forced conveyance of the waste to be compacted, rather it is only non-positively loaded by the roller, and the waste to be compacted is also exposed to the ambient air during the conveying process.
  • the pressing process takes place in that the garbage to be compressed in front of the conveying surface a plunger is brought through a shaft or the like, so that the garbage to be compacted is compressed during the piston stroke and optionally pushed into a container.
  • Such an arrangement can also be arranged vertically so that the waste to be compacted is conveyed under the pressing surface of the piston.
  • the waste can be conveyed into a container, a sack or the like at the same time.
  • a disadvantage of the known arrangements is that either the garbage is exposed to the ambient air during the conveying process and that the promotion is uneven due to the non-positive loading of the garbage, or that the arrangements with a plunger make it difficult to remove the waste in to bring a sufficient amount in front of or under the pressing surface, and in this case too, the waste is in contact with the ambient air during the conveying process, so that unpleasant odors and the like can occur.
  • the invention is accordingly based on the object of designing a compression device of the type mentioned at the outset, that the garbage is conveyed with certainty at regular intervals into a receptacle or the like and that odor nuisances caused by the garbage being conveyed cannot occur during the conveying process.
  • a rotatable and driven cylindrical drum is provided in a housing, each with an approximately perpendicular material feed and material discharge channel, which has a cross-sectionally square or rectangular shaft symmetrical to the drum, the drum of which Sheath penetrates and which serves to accommodate a compression piston adapted in cross section, which has two partially cylindrical, opposing jacket surfaces, the radii of which correspond to the radius of the drum, and whose distance is smaller than the diameter of the drum, with two mutually opposite planes between the jacket surfaces Surfaces are arranged, the distance between them is also smaller than the diameter of the drum and the compression piston has a slot-like guide arranged at an angle to the shaft in a plane extending perpendicular to the drum axis , the ends of which point towards the rear connecting edges in the direction of rotation of the drum between the partially cylindrical and the flat lateral surfaces of the drum, with a fixed pin engaging in the guide, the Axis lies in the vertical central plane through the drum and its outer diameter corresponds to the distance between the two straight surfaces
  • the outer surface of the piston moves in this last compression position together with the drum on one at the exit of the discharge channel arranged scraper edge along so that rubbish adhering to the piston is scraped off and conveyed into the receptacle.
  • the garbage is always closed off from the ambient air both in the receiving chamber of the piston shaft and in the receiving container, so that the garbage is conveyed cleanly without any unpleasant odors or the like.
  • the drum is expediently mounted between two walls extending perpendicular to its axis, with which the pin is also connected in a stationary manner. This causes the piston to move over the pin and guide it.
  • the stroke of the piston is therefore greater, the further the pin is offset from the center of the plane of the drum axis to the receptacle.
  • the size of the stroke of the piston finds its limits in the circumferential geometry of the piston, since its cylindrical outer surfaces must complement the drum cross section in their outermost position. If the piston or the jacket protruded in any position beyond the circumference of the drum, this would result in the drum jamming and thus in faults. If the stroke was too small, in the case of which the piston, with its lateral surfaces, would not reach those of the drum in the outfeed position to the receiving container, chambers containing garbage would remain open. This residual waste would not or not sufficiently past the scraper edge, so that the waste contained in these chambers would stick to the piston.
  • the pin diameter is as large as the distance between the inner surface of the slot-like guide facing a cylindrical outer surface and the parallel tangent to the outer surface.
  • the diameter of the pin should therefore be as large as possible in order to keep the loads on this device part small.
  • the shaft has a width which corresponds approximately to the length of the shaft in the region of the cylindrical walls.
  • the shaft can therefore be cube-shaped overall.
  • the piston is therefore guided with its flattened flat surfaces within the shaft of the drum, and considerable forces which can act as clamping forces can occur in the edge region of these surfaces. About these powers to catch, it is useful if the end faces of the drum are provided on their inner sides with additional straight guides for the piston. This is easily possible because the piston only moves in a straight line with respect to the drum.
  • the outer walls of the housing for the drum or at least one of them can expediently be designed such that they can spring outwards in order to be able to accommodate a possibly non-fit waste piece without damaging the device.
  • the receptacle can have the shape of a receptacle bag or the like, it is expediently held in such a way that it can be removed when filled.
  • a measuring instrument can also be provided which detects the pressing pressure inside the receptacle and stops the device when the receptacle is full.
  • This measuring device can consist of a base plate or the like, which is actuated via a gear, a limit switch or the like.
  • a safety cover which is expediently located slightly above the casing of the drum and which is closed during the conveying process, it being possible for a safety circuit to be provided which stops the drive of the drum when the safety cover is open.
  • the compression device according to the invention is particularly suitable for use in the household, i.e. in other words with a filling volume of around 12 liters.
  • the fixed pin can be elastically mounted, so that when the wall pressure is increased by solid components, the pin can move in the opposite direction, so that instead of the movable wall of the pin takes over the task of preventing damage.
  • the pin is mounted on a torsion bar which is rotated when the pin deflects and forms the corresponding spring.
  • the device according to the invention consists of a drum 2 rotating in a housing 1, which is provided with a shaft 3, which extends symmetrically through the drum from its cylindrical lateral surfaces 4 and receives a piston 5, which is inside the shaft 3 in the direction the arrow 6 performs a stroke during the rotary movement of the drum and thereby the waste to be compacted from one Receiving shaft 7 receives and promotes simultaneous compression in a lower receiving container 8.
  • the movement of the piston 5 is hereby caused by the fact that the piston 5 is provided with an elongated hole-like guide 9, in which a fixed pin 10 engages, which in the exemplary embodiment shown sits on a fixed support 11 connected to the fixed housing 1.
  • the circumferential surface of the piston 5 consists of two mutually opposite, partially cylindrical jacket sections 12 (see also FIG. 5), between which there are two flat jacket sections 13 (see also FIG. 5). 5, the distance A between the two planar jacket sections 13 corresponds to the width of the shaft 3, so that the piston 5 is guided in the stroke direction within the shaft. This guidance can be supported by guide elements such as grooves 14, webs 15 or the like (cf. also FIG. 4).
  • Fig. 1 a position of the drum and piston is shown, in which the upper part of the shaft 3 forms an upwardly open receiving chamber 17, so that the chamber 17 can be filled with garbage to be compacted when the drum is at a standstill but also while the drum is rotating .
  • the drum 2 is now in the housing 1 In the direction of the arrows 16, that is to say counterclockwise, the waste is pre-compressed in the receiving chamber 17 according to FIG. 2, since the waste is drawn into the device on the left in FIG. 2.
  • the piston is moved via the slot-like guide 9 to the outside of the drum (downward to the left in FIG.
  • Fig. 4 shows an exploded schematic and perspective view of the device in detail.
  • the shaft 3 in the drum 2 can be formed by two individual parts 2a and 2b with a cylindrical outer wall, which can be connected to one another and to one another by covers 18 and 19.
  • the housing 1 (cf. also FIG. 1) has upper channel sections 1 a, which serve to fill the garbage into the device.
  • the edge 20 facing the drum (cf. also FIG. 1) can be designed as a scraper which detaches the garbage from the drum 2.
  • part 1b of the wall encompassing the drum is formed as an elastically resilient section, so that jamming caused by large pieces of waste or the like is avoided.
  • the fixed pin 10 engaging in the guide 9 of the drum 5 can be mounted on a torsion bar 22 which is rotated when the pin 10 deflects and forms the corresponding spring.
  • Fig. 6 is a section approximately along the line VI-VI of Fig. 1 and illustrates an embodiment of the constructive expansion of the arrangement according to the invention.
  • the pin 10 engaging in the elongated hole 9 is fixed in place on a part 25 of the housing 1, for example via a flange 26.
  • a roller bearing 27 forms part of the pin 10 and the slot-like guide 9 has corresponding dimensions, so that the bearing 27 is received by the guide 9.
  • the drum 2 is rotatably mounted on the rear cranked part 10a of the pin 10 via a flange 28, this rear part being aligned with a shaft section 29 which is connected to the wall of the drum 2 directly or via a flange 30 or the like.
  • the shaft section 29 is rotatably mounted in the housing 1 via a bearing 31, so that the drum 2 can be driven approximately in the direction of the arrow 32 by means of a motor 23 via an intermediate gear 24 such as a worm or the like (see FIG. 4).
