Definitions

  • the invention can be usefully employed for disposal of waste products, especially sacks made of flexible materials (paper, sacking, jute, plastic etc.) which are used to pack powder or granular materials.
  • the sacks are opened by laceration in a bag-breaking machine, which separates the sack from its contents, after which the broken sacks, by now waste material, are compacted into bundles and sent on for disposal.
  • the prior art teaches a compacting machine for forming bundles from loose objects, comprising a pressing chamber which is filled loosely with objects to be compacted.
  • the known machine comprises a compacting organ, for example a conveyor screw, which conveys the objects and stows them progressively in the pressing chamber, up until a compact and fairly uniformly firm bundle is formed.
  • the bundles formed using known-type compacting machines are not uniformly pressed, but rather there are parts of the bundles which are more greatly compacted than others.
  • the main aim of the present invention is to obviate the above-mentioned limitations and drawbacks in the prior art, by providing a machine able to form bundles the disposal of which is relatively rapid and economical.
  • An advantage of the invention is that it makes available a machine for forming highly-compacted bundles which are also highly resistant and firm, without excessively compressing the materials.
  • a further advantage of the invention is that it enables uniform compaction of the bundles.
  • a further advantage of the invention is that it makes available a constructionally simple and economical machine.
  • l denotes in its entirety a machine for forming bundles of elongate shape, basically cylindrical and made up of compacted objects inside a sack.
  • the machine l is especially suitable for use in the processing of objects 2 comprising waste materials coming from a bag-breaking machine.
  • the compacting-packing machine 1 can be associated to a bag-breaking machine and receive the waste material therefrom, which waste material can be slashed bags made of paper, sacking, jute, plastic or another flexible material used for making sacks for packing granular and/or powder material.
  • the machine 1 compacts the waste bags coming from the bag-breaking machine and packs the bags into an elongate cylindrical bundle.
  • the compacting-packing machine l comprises a tubular conduit 3 having an inlet 4 and an outlet 5 for the objects 2 to be compressed and packed in bundles.
  • the conduit 3 is longitudinally extended in a horizontal direction.
  • the inlet 4 comprises an upper opening through which the objects can be introduced into the conduit 3.
  • At least a part of the end of the conduit 3 is cylindrical.
  • a sack 6 can be attached about this cylindrical part; the sack 6 can be made of plastic, be tubular in shape and can have an opening at one end while the other end, the bottom end, is closed.
  • the sack 6 can be fitted on the conduit 3 so that the bottom of the sack 3 is up against the outlet 5 of the conduit 3.
  • An advancement device is predisposed inside the conduit 3, for conveying the objects introduced in the conduit 3 towards the outlet 5 and therefore towards the bottom of the sack 6 fitted about the conduit 3.
  • the advancement device comprises a conveyor screw 7, coaxial to the tubular conduit 3 and made to rotate about its own axis x-x by a motor 18.
  • At least a tract of the conveyor screw 7 preferably comprises a self-supporting spiral, with no central support shaft but having at its centre an axially-extending empty space.
  • the first tract of the conveyor screw 7 is surrounded by a deformable and flexible guard 13, comprising a truncoconical wall made of an elastomer.
  • the guard 13 has been seen to prevent (or at least considerably reduce the risk of) the objects' stalling in the conduit 3, i.e. a situation in which the conveyor screw 7 rotates without being able to advance the objects in the conduit 3.
  • One of more ribs 14 are also provided for the same reason; the ribs 14 are extended in axial direction and are solid in rotation with the conveyor screw 7.
  • At least one striker element is located close to the outlet 5 of the conduit 3; in the example this striker element is constituted by a truncoconical wall 8 converging towards the axis of the conduit 3.
  • the wall 8 has at its centre an opening for the passage of the objects.
  • the wall 8, which is made of an elastomer material, is deformable when the objects pass through the outlet 5.
  • the truncoconical wall 8 comprises an annular diaphragm which is elastically deformable when the objects pass through it, i.e. it is a diaphragm which does not completely obstruct the outlet 5 of the conduit 3, but allows the objects 2 to exit from the conduit 3 by effect of a pressure exerted by the advancement device.
  • the truncoconical wall 8 can exhibit on its periphery a plurality of cuts arranged circumferentially to increase the deformability of the wall 8.
  • the wall 8 is situated immediately before the conduit outlet 5.
  • the conveyor screw 7 terminates at the central opening of the wall 8. The terminal tract of the screw 7 converges.
  • the machine 1 is provided with a tubular or annular element, constituted in the example by a collar 9, located after the conduit outlet 5, coaxially with respect to the outlet 5.
  • the collar 9 is positioned immediately after the outlet 5 of the conduit and externally of the sack 6 fitted about the conduit 3.
  • the collar 9 is stretchable to allow a widening thereof, is truncoconical and has a plurality of circumferential cuts made in its peripheral edge to increase its deformability.
  • the collar 9 is constrained by elastic means predisposed in order to enable the collar 9 to make axial distancing movements from the outlet 5 in the direction indicated by the arrows G.
  • the collar 9 is connected to a fixed part of the machine (the conduit 3 or a frame, for example) by a plurality of elastic springs 10 having an end removably hooked to the fixed part.
  • the axial movements in direction G enable the collar 9 to adapt itself to the bundle under formation, as will be better explained herein below.
  • a channel 11 is located downstream of the collar 9, and consists of a support plane, delimited by lateral edges, along which the forming bundle drags as it fills.
  • the sack 6 fitted about the conduit 3 is progressively unfolded from the conduit 3 by effect of the advance of the objects 2 pushed by the conveyor screw 7.
  • the objects 2 exiting from the conduit are shoved by the screw 7 against the wall 8 and forced to pass through the opening at the centre of the wall 8.
  • the objects 2 are then crushed between the conveyor screw 7 and the wall 8, then to be pushed into the sack 6.
  • the mass of the compacted objects 2 introduced into the sack 6 forms a cylindrical and elongate bundle 12.
  • the collar 9 interacts contactingly with the external lateral surface of the sack 6 as it is unfolded from the conduit 3, laterally stretching the bundle 12 as it is being formed.
  • the collar 9 makes sure that the unfolding of the sack 6 from the conduit 3 is ordered and regular. Further, the collar 9 contributes to making the bundle 12 regular in shape the objects 2 uniformly compacted.
  • the collar 9 can move axially in direction G (figure 4), distancing from the outlet 5 of the conduit 3, thanks to the springs which constrain it to the machine.
  • the striker element is, in the illustrated embodiment, a truncoconical wall 8 or flexible diaphragm which is open in its centre; but it could be made differently, for example it could be constituted by a diaphragm with cuts in the centre, with the flaps created by the cuts being reciprocally distanced by the thrust of the objects 2, in effect opening the diaphragm and allowing the objects 2 to pass through.
