Definitions

  • the present invention relates to a device for compacting plastic containers, in particular bottles.
  • plastic containers such as for example bottles of mineral water
  • the collection and storage of such objects poses the problem of the profitability of their recovery, due to the low weight of each container, compared to its volume.
  • the present invention aims to provide a device for compacting such objects for collection so as to increase the profitability of their recovery.
  • the present invention relates to a device for compacting plastic containers, especially bottles, characterized in that it comprises in combination a receptacle of substantially cylindrical shape provided with an inlet orifice at one of its ends and an outlet at its other end, and a crushing member having a lower part of convex shape directed downwards, able to be moved between a first position in which it is outside the receptacle and a second position in which its lower part is in the vicinity of the lower part of the receptacle, after having crushed a container.
  • Such a device can for example be intended to equip the recovery containers for materials left available to the public in urban areas.
  • the device according to the invention is mounted inside the container, the inlet orifice of the receptacle being located opposite an opening provided on the container for the introduction of the objects.
  • the operation of the crushing member is advantageously carried out using a pedal accessible from the outside of the container by means of a transmission mechanism to the crushing member. of the action exerted by the user on the pedal.
  • the receptacle is inclined, the outlet orifice being placed at a height less than that of the inlet orifice.
  • the plastic containers introduced into the receptacle are naturally positioned inside of it by their own weight.
  • plastic container is understood to mean mainly bottles of the type of those containing mineral water or similar containers.
  • the outlet orifice includes a stop which makes it possible to stop the bottles inside the receptacle with a view to their crushing.
  • Such a stop is provided at a distance from the outlet orifice such that the middle part of a plastic bottle is located to the right of the crushing member.
  • a suitable mechanism makes it possible to maneuver this stop so that it is in the closed position at the start of the crushing cycle, then in the open position after the crushing to allow the escape of a bottle which has just been overwritten, then back to the closed position at the end of the overwrite cycle.
  • the crushing member is pivotally mounted about an axis substantially parallel to the axis of the receptacle.
  • the upper part of the receptacle comprises in this case an opening allowing the passage of the crushing member during the movement of the latter between its first and its second position.
  • a plastic bottle collapses in the following way: considering the two halves of the bottle located on either side of a median plane, the lower half of the bottle is resting against the lower part of the receptacle of which it substantially matches the shape while the upper half of the bottle sees its convexity reverse by coming to be applied substantially against its lower half.
  • the crushed bottle according to the invention is then substantially in the form of a half of a bottle cut by a plane passing through its axis.
  • the lower concave part of the crushing member bears on the lower part of the receptacle so as to pinch the region of the bottle folded along two of its generatrices diametrically opposite.
  • Such a pinching makes it possible to stabilize the collapsed shape of the bottle by crushing the plastic material on the lateral edges of half of the bottle.
  • the crushing member comprises on its lower part perforation means which facilitate the crushing of a hermetically closed bottle by piercing it beforehand.
  • such perforation means are in the form of bevelled metal tubes which protrude slightly from the lower part of the crushing member while the part bottom of the receptacle is provided with orifices located opposite said metal tubes when the crushing member is in its second position inside the receptacle.
  • the outlet orifice of the receptacle is closed by a retractable articulated part.
  • This part is retained in the closed position by a return means which is calibrated so that said part can free the passage in the case where a full bottle is introduced into the receptacle.
  • a safety shutter is provided at the inlet opening of the receptacle.
  • Such a shutter is connected to the crushing member so as to close the inlet opening of the receptacle during the crushing of a bottle and to prevent the user from engaging an arm, for example.
  • a device makes it possible to prevent the operation of the crushing member if an obstacle hinders the closing of the shutter during the crushing operation. Thus, possible accidents which could occur during the use of the device according to the invention are avoided.
  • the safety shutter closes the inlet opening of the receptacle at the same time as the crushing member moves from its first position to its second position.
  • any obstacle preventing the closing of the safety shutter causes the blocking of the crushing member and interrupts the crushing cycle.
  • the safety shutter closes the inlet orifice prior to actuation of the member which cannot be moved if the safety shutter is not in the fully closed position.
  • the container 1 of Figures 1 and 2 is of the type traditionally used for the selective collection of garbage.
  • a compacting device according to the invention is placed inside the container 1 with the inlet orifice of its receptacle facing the orifice 2 of the container.
  • the compacting device 3 rests on a base 4 which rests on the bottom of the container.
  • the base 4 has a vertical branch 5 in the vicinity of the wall before the of the container.
  • the branch 5 is hollow and has a longitudinal slot on its face oriented towards the outside of the container. It constitutes a guide rail for a pedal 6 located close to the ground and accessible from outside the container.
  • the pedal 6 makes it possible to actuate the compacting device 3 by means of a cable 7 secured to the pedal 6 at one of its ends and to the crushing member of the compacting device 3 at its other end.
  • Pulleys 8 guide the cable.
  • the compacting device 3 comprises a receptacle 9 of substantially cylindrical shape and a crushing member 10 articulated around an axis 11 so as to be able to pivot between a first position shown in FIG. 3 where it is located outside the receptacle 9 and a second position, not shown, where it is located inside the receptacle 9.
  • the axis of receptacle 9 is inclined so that the inlet port 9a is at a height greater than that of the outlet 9b of the container.
  • the lower part of the receptacle 9 described here comprises, in cross section, two branches inclined towards the inside which are symmetrical with respect to the vertical median axis of the receptacle and by a horizontal branch which joins the lower ends of the two inclined branches.
  • Each branch of this cross section corresponds to a flat wall which extends along the axis of the receptacle.
  • the crushing member 10 is constituted, in the illustrated embodiment, by four blades 12 a -12 d whose shape corresponds substantially to the internal cross section of the lower part of the receptacle 9.
  • the crushing member 10 On one of the blades 12 b , the crushing member 10 comprises three bevelled hollow tubes 12 e directed downwards in the crushing position of the crushing member.
  • Such tubes constitute perforation members which facilitate the crushing of a hermetically closed bottle by creating in the wall thereof passages for the air which it contains.
  • a plate 12 f having an orifice in the extension of each tube 12 e is mounted axially sliding relative to the latter by being pushed outwards for example by springs.
  • Such a plate makes it possible both to conceal the hollow tubes 12 e when the crushing member is in the extended position relative to the receptacle 9 and to extract the hollow tubes from the wall of the bottle after the crushing of this last.
  • One of the blades 12 d the closest to the inlet orifice 9 a of the receptacle, has a recess for the passage of the neck of a bottle introduced with its base forward.
  • the neck is located near the outlet orifice of the receptacle and not opposite one of the blades 12.
  • the four blades 12 are welded to a bracket 13, the two lateral branches of which are pivotally mounted around the axis 11.
  • a lug 14 welded in the central part of the bracket 13 extends outwardly parallel to the lateral branches of said bracket. It comprises a longitudinal slot 15 which crosses it perpendicularly and through which the cable 7 is subjected to a retaining part capable of sliding in line with the slot.
  • the cable 7 is returned to the pedal 6 by means of pulleys 8.
  • the blades 12 have, in their upper part in the crushing position, a width slightly greater than the corresponding part of the lower part of the receptacle.
  • a plastic bottle crushed by the compacting device is mainly pinched along the lateral edges of the lower part of the receptacle on which the blades 12 rest.
  • the receptacle 9 is partially closed at its upper part by a rolled sheet in the shape of a cylinder 16 which has cutouts allowing the tilting of the bracket 13 inside the receptacle 9, the tab 14 penetrating into a slot provided for this purpose in sheet 16.
  • a stop 17 which makes it possible to stop the bottles inside the inclined receptacle with a view to their crushing.
  • the stop 17 is actuated by an appropriate mechanism which controls its positioning as a function of the angular position of the crushing member 10.
  • This mechanism comprises a part 18 which is secured in rotation to the bracket 13 by means of a U-shaped part 19 which is welded on the one hand to one of the branches of the bracket 13 and on the other hand at room 18.
  • FIGS. 4, 5 and 6 Such a mechanism is shown in the detailed views of FIGS. 4, 5 and 6.
  • the part 19 has a lug 20 on one of its faces, as well as a recess 21 in the vicinity of the lug 20.
  • the stop 17 is mounted on a lever 22 mounted pivoting about an axis 23 parallel to the axis 11.
  • the lever 22 also has two lugs 24 and 25 on its side placed opposite the lug 20 and the recess 21 of Exhibit 19.
  • FIGS 5 and 6 there is shown the control mechanism of the stop 17 during the crushing cycle.
  • the lug 20 of the part 19 pivots about the axis 11, at the same time as the crushing member 13. During this pivoting, the recess 21 exceeds the lug 24, while that the lug 20 meets the lug 24 which causes the lever 22 to tilt.
  • the stop 17 then locks in its retracted position, for example by pressing on the edge 26 of the receptacle outlet orifice.
  • the crushing member 10 is raised enough to release the crushed bottle which escapes from the receptacle by sliding towards its outlet orifice.
  • the action of the lug 20 on the lug 25 causes the stop 17 to return to position, which is thus able to stop a next bottle with a view to its crushing.
  • FIGS. 7 and 8 show the stop 17 and the lever 22 seen from above with respect to FIG. 4.
  • the stop 17 is mounted around a vertical axis 27 on the lever 22 and that a spring 28 exerts a traction on the end of the stop 17 located on the side of the lever 22 in the direction of maintenance of the stop 17 in alignment with the lever 22.
  • the spring 28 is fixed at its other end to a rod 29 integral with the lever 22.
  • the length of the rod 29 is determined, depending on the stiffness of the spring 28, so that the latter exerts on the stop 17 a restoring force which is such that a plastic bottle is stopped in the receptacle 9 to be crushed (figure 7) while a glass bottle, of higher weight, crosses the outlet orifice of the receptacle by pushing the stop 17 (figure 8).
  • the length of the rod 29 can advantageously be adjusted by using a threaded rod on which a nut is screwed to which the spring 28 is subjected.
  • a safety device On the side of the inlet opening 9a of the receptacle is provided a safety device which makes it possible to prevent the operation of the member from being crushed, for example in the case where a user introduces his arm into the opening Entrance.
  • the device comprises a shutter 30 of its inlet orifice which is integral in rotation with the crushing member by means of a drive mechanism shown in FIGS. 9 to 11.
  • the shutter 30 is pivotally mounted around the axis 23. This arrangement has been chosen for reasons of convenience, but it is clear that a different axis of rotation could be used for the shutter 30 than that which is used for tilting. lever 22.
  • FIG. 9 the receptacle 9, the crushing member 10 and the shutter 30 are shown diagrammatically in dashed lines.
  • the actual drive device consists of a rack 31 and a part 32 provided with a lug 33.
  • the rack 31 is welded to one of the branches of the bracket 13 around the axis of rotation 11.
  • the part 32 is welded to a metal tube 34 engaged around the axis 23 and secured to the shutter 30 at its other end. In other words, the part 32 is integral in rotation with the shutter 30.
  • the parts 31 and 32 each have a pivot 35 and respectively 36 connected by a connecting rod 37.
  • connecting rod 37 While the connecting rod 37 is held around the pivot 35 on the rack 31, it is simply hooked on the pivot 36 of the part 32.
  • it has a notch 38 in which the pivot 36 engages, a spring 39 being stretched between the axis 11 and the upper end of the connecting rod 37 to press the bottom of the notch 38 against the pivot 36.
  • the rack 31 and the part 32 therefore move in the manner of a deformable parallelogram around two fixed points which constitute the axes 11 and 23.
  • the rack 31 continues to pivot around the axis 11.
  • the connecting rod 37 then descends relative to the pivot 36 which emerges from the notch 38.
  • the teeth of the rack meet the lug 33 which engages in one of them and thus prohibits any additional angular movement of the rack 31 in the direction of the receptacle.
  • the rack mechanism 31 and lug 33 of the safety device can be replaced by other mechanisms providing equivalent kinematics, for example a mechanism comprising a cam, in place of the rack, and a stop in the form of an angular sector in place and place of the ergot. Such a stop prevents the cam from lowering until the shutter 30 has not completely closed the bottle introduction orifice.
  • the safety device could act so as to ensure first of all the complete closure of the shutter 30 and then the movement of the member 10, on the sole condition that the shutter 30 is in position closed.
