- control mechanism 19 is also configured to determine the movement of the partition 17 in order to facilitate the fall of the waste 7 into the fall compartment 14, preferably at the time when the presser 13 returns in the rest position.
- control mechanism 19 comprises at least one first tie rod 30 mechanically connected to the actuation lever 20.

- the waste 7 is pressed against the partition 17 and the loading tank 5 turns the concavity 6a outwards from the containment structure in order to allow the introduction of a new waste.

- Figure 3 shows an operating step in which a user accesses the compactor device 1 by pressing the pedal 21 downwards.
- the stroke made by the actuation levers 20 leads to the actuation of the primary lever 23 of the control mechanism 19. Consequently, the secondary lever 26, controlled by the first connecting rod 24, leads to the rotation of the loading tank 5 in the receiving position, so as to allow the introduction of a waste 7 inside the concavity 6a, through the introducing mouth 3 available on the front wall 4.
- the second connecting rod 25 causes the presser 13 to be lowered towards the partition 17.
- the movement of the primary lever 23 imposes, through the first tie rods 30, an approaching of the first movable crosspiece 35 to the second movable crosspiece 36, determining the mutual engagement of the first and second grasping members 33, 34.
- Figure 4 shows the compactor device 1 during the ascent of the control pedal 21 following its release by the user.
- the traction springs 29 bring the actuation levers 20 back to the rest position, while the loading tank 5 is returned to the closure position by means of the control mechanism 19.
- the primary lever 23 brings the first tie rods 30 back the initial position and, due to the mutual engagement between the first and second grasping members 33, 34, the translation of the partition 17 towards the second position, below the first portion 11, is determined by means of the second tie rods 31.
- the action of the fixed cams 38 determines the mutual disengagement of the first and second grasping members 33, 34 with the resultant returning of the partition 17 in the first position as shown in figure 5 .
- Figure 6 shows the compactor device 1 when a user activates the pedal 21 again to introduce a new waste 7 into the loading tank 5.
- the pedal 21 When the pedal 21 is actuated again, the lowering of the presser 13 towards the operating position causes the previously introduced waste 7 to be pressed against the partition 17.
- the step 18 arranged between the upper portion 11 and the lower portion 12 of the transfer chute 10 facilitates the effective retention of the waste 7, preventing it from rising up along the transfer slide 10 during the crushing step.
- the new waste 7 descends along the transfer chute 10 and will be stopped between the presser 13 relocated in the operative position and the partition 17 relocated in the first position, again arranging the compactor device 1 in the condition of figure 5 for the execution of further operating cycles.
- the compactor device 1 is designed for the collection of plastic bottles, and the sizes of its components are studied for the purpose of the treatment of this waste type.
- a discharge port L is defined between the presser 13 in the rest position and the lower part 12 of the transfer chute 10, i.e., between the presser 13 and the partition 17 in the first position.
- the discharge port L has a greater amplitude than the minimum size detectable on the waste 7 to be disposed into the compactor device 1. It is thereby prevented that the non-crushed waste 7 may fall into the collection compartment 14.
- the discharge port L is large enough to permit the passage of smaller bodies, such as pieces of wood, stones or other objects other than those whose collection the compactor device 1 is designed for.
- an unlocking mechanism 39 which can be activated by the user is also preferably provided, to determine the sliding of the partition 17 towards the second position independently of the actuation of the presser 13 and/or other members of the compactor device 1.
- the release mechanism 39 comprises an auxiliary lever 40 which can be activated by means of a respective release pedal 41, for controlling the movement of the partition 17 by means of at least one respective auxiliary tie rod 42.
- an auxiliary opening 43 is arranged on the front wall 4 for introducing caps or other closure elements previously removed from the bottles 7 to facilitate their crushing. Downstream of the auxiliary opening 43, the caps may be conveyed to an auxiliary container, not shown.
- the compactor device 1 may also be provided with a user identification system by reading IRFD cards or other type of code, e.g., through a special reader 44 and a printing unit housed in the containment structure to issue through a slit 45 receipts attesting the use of the compactor device 1.
- the reader 44 and the printer may be powered by batteries which may be recharged, if needed, using photovoltaic panels, without no need of connections to power supply networks.

number 1 globally indicates a compactor device for the collection ofwaste 7, according to the present invention. - The
compactor device 1 comprises a substantially box-shaped containment structure 2, made e.g., of metallic material, having an introducingmouth 3 at its top. More specifically, the introducingmouth 3 is preferably formed in the upper part of afront wall 4 of thecontainment structure 2. Thefront wall 4, or at least the part thereof bearing the introducingmouth 3, preferably extends on a substantially vertical plane or with a slight tilt with respect to the vertical. - A
loading tank 5, arranged so as to occlude the introducingmouth 3, is oscillatably secured to thecontainment structure 2. In other words, theloading tank 5 prevents a user from introducing his hands and/or objects directly into thecontainment structure 2 through the introducingmouth 3. - The
loading tank 5 may be substantially shaped like a cylindrical sector, with acontainment wall 6 thereof defining a concavity 6a suitable for receiving at least onewaste 7, e.g., a plastic bottle, to be disposed of into thecompactor device 1. The concavity 6a is preferably delimited between a pair ofside walls 8 arranged at the opposite end edges of thecontainment wall 6. Theloading tank 5 can be rotatably hinged to one or more supports 9 integral with respect to thecontainment structure 2, e.g., near itsside walls 8, preferably around a substantially horizontal rotation axis X. - The
loading tank 5 is movable about its rotation axis X between a receiving position (figures 3 and6 ), in which it has its concavity 6a facing the outside of thecontainment structure 2 for receiving at least onewaste 7, and a closure position (figures 2 and5 ), in which said concavity 6a faces thecontainment structure 2 internally. - Near the

contrast surface 17a is preferably out of alignment with respect to the sliding surface 11 a of theupper portion 11 of thetransfer chute 10. Astep 18 is preferably defined in the transition zone between theupper portion 11 and thelower portion 12 of thetransfer chute 10. - In the second position, the
contrast surface 17a of thepartition 17 is placed parallel alongside to theupper portion 11, in an underlying position with respect to the latter. Thepartition 17 thus turns out to be away from thepresser 13 to release the fall of thewaste 7 in thefall compartment 14. - Preferably, the translation of the
partition 17 towards the second position is opposed by return springs 17b, counterweights or other suitable repositioning members, operating for example between the partition itself and a fixed portion with respect to theupper portion 11 of thetransfer chute 10. - At least one
control mechanism 19, preferably housed above thefall compartment 14, is mechanically connected to anactuation lever 20 protruding out of thecontainment structure 2. In the illustrated example there is provided a pair of actuation levers 20 interconnected with each other by a pedal 21 extending horizontally near a lower area of thefront wall 4. - Each
actuation lever 20 is rotatably constrained to a side wall of thecontainment structure 2 for actuating, with its opposite end to thepedal 21, athrust strut 22 operating on thecontrol mechanism 19. - The
control mechanism 19 preferably presents, next to each of theside walls 8 of thecontainment structure 2, aprimary lever 23 having afirst end 23a rotatably constrained with respect to thecontainment structure 2. A first connectingrod 24 and a second connectingrod 25 are constrained to theprimary lever 23. - The first connecting
rod 24 controls, on the opposite side of theprimary lever 23, asecondary lever 26 operatively connected to theloading tank 5. - Preferably, the
secondary lever 26 has a proximal end 26a constrained with respect to thecontainment structure 2, and a distal end 26b bearing aslot 27 crossed by a constrainingpin 28 integral with one of theside walls 8 of theloading tank 5. - The second connecting
rod 25 is, in turn, constrained to thepresser 13, to control its rotation around its own hinging axis Y with respect to thecontainment structure 2. - The activation of the
compactor device 1 provides that the actuation levers 20 translate between a rest position and an actuating position by a thrust action exerted by the user on thepedal 21. Preferably, at least onetraction spring 29 or equivalent return members elastically counteract the translation of the actuation levers 20 towards the actuating position. - In the rest position (
figures 2 and5 ), thesecondary lever 26 retains theloading tank 5 in its closure position. At the same time, the second connectingrod 25 holds thepresser 13 in a respective rest position in which thethrust surface 13a faces thetransfer chute 10, according to a tilted orientation with respect to the latter. In this case, thethrust surface 13a of thepresser 13 is suitable for intercepting the descent of thewaste 7 along thetransfer chute 10, to stop it at thepartition 17 of the lower portion 12 (figure 5 ). - In the activation position, i.e. with the pedal 21 lowered (
figures 3 and6 ), thesecondary lever 26 causes a translation of theloading tank 5 from the closure position to the receiving position to allow the introduction of awaste 7 into theloading tank 5. At the same time, the second connectingrod 25 causes a translation of thepresser 13 towards thetransfer chute 10 to cause a crushing of awaste 7, if any, previously transferred from theloading tank 5 to thetransfer chute 10. - Preferably, the
control mechanism 19 is also configured to determine the movement of thepartition 17 in order to facilitate the fall of thewaste 7 into thefall compartment 14, preferably at the time when thepresser 13 returns in the rest position. - For this purpose, it may be provided, for example, that the
control mechanism 19 comprises at least onefirst tie rod 30 mechanically connected to theactuation lever 20. In the illustrated example there is provided a pair offirst tie rods 30 in the form of rods spaced parallel to each other. Eachfirst tie rod 30 is preferably connected to a second end 23b of theprimary lever 23, e.g., in a common hinge point C with the second connectingrod 25. - At least one
second tie rod 31, e.g., comprising one or more cables guided through respective return pulleys 32, is mechanically connected to thepartition 17 of thetransfer chute 10. - First and second grasping
members second tie rods movable crosspiece members elements 33, e.g., in the form of arms which may elastically oscillate around respective hinge pivots 37 (figure 3a ), which may be engaged and disengaged withrespective engagement seats 34 carried by the secondmovable crosspiece 36, overcoming the resilient strength of contrast springs (not shown). Alternatively, the first and second graspingmembers - The
first tie rods 30 are movable towards thesecond tie rods 31 as a result of the translation of the actuation levers 20 towards the actuating position due to a thrust exerted on thepedal 21, so as to bring the first graspingmembers 33 into engagement with the second graspingmembers 44, as better shown infigure 3a . - Once the actuating position has been reached by the operating levers 20, the
waste 7 is pressed against thepartition 17 and theloading tank 5 turns the concavity 6a outwards from the containment structure in order to allow the introduction of a new waste. The action exerted by the user on the pedal 21 leads to the crushing of the waste previously introduced at the time when the loading tank has been opened for introducing thenew waste 7. - When the
pedal 21 is released, the action of the traction spring(s) 29 leads to the translation of the actuation levers 20 towards the release position, with the simultaneous translation of thepresser 13 towards the rest position. The mutual engagement of the first and second graspingmembers partition 17 to be translated by the action of thesecond tie rods 32 away from thepresser 13, sliding below theupper portion 11 of thechute 10. After reaching the second position of thepartition 17, the first graspingmembers 33 interfere on respective fixed cams 38 (figure 3a ), which cause their disengagement from the second graspingmembers 34. - Thus, the
movable crosspieces second tie rods partition 17 is repositioned in the first position by the return springs 17b. -
Figures 2 ,3 ,4 ,5 ,6 and7 show the operating sequence of thecompactor device 1 during the execution of two consecutive work cycles, starting from a hypothetical initial condition in which the device has never been used so far. - This initial condition is shown in
Figure 2 , in which the actuation levers 20 are in the rest position and keep the pedal 21 in the elevated position. Theloading tank 5 is in the closure position, while thepartition 17 is in the respective first position, below thepresser 13 kept, in the rest position, elevated at a certain distance from the partition itself. No object is interposed between thepresser 13 and thepartition 17. -
Figure 3 shows an operating step in which a user accesses thecompactor device 1 by pressing the pedal 21 downwards. The stroke made by the actuation levers 20 leads to the actuation of theprimary lever 23 of thecontrol mechanism 19. Consequently, thesecondary lever 26, controlled by the first connectingrod 24, leads to the rotation of theloading tank 5 in the receiving position, so as to allow the introduction of awaste 7 inside the concavity 6a, through the introducingmouth 3 available on thefront wall 4. - Simultaneously with the rotation of the
loading tank 5, the second connectingrod 25 causes thepresser 13 to be lowered towards thepartition 17. At the same time, the movement of theprimary lever 23 imposes, through thefirst tie rods 30, an approaching of the firstmovable crosspiece 35 to the secondmovable crosspiece 36, determining the mutual engagement of the first and second graspingmembers -
Figure 4 shows thecompactor device 1 during the ascent of thecontrol pedal 21 following its release by the user. The traction springs 29 bring the actuation levers 20 back to the rest position, while theloading tank 5 is returned to the closure position by means of thecontrol mechanism 19. Simultaneously, theprimary lever 23 brings thefirst tie rods 30 back the initial position and, due to the mutual engagement between the first and second graspingmembers partition 17 towards the second position, below thefirst portion 11, is determined by means of thesecond tie rods 31. - Just as the
partition 17 reaches the second position, the action of the fixedcams 38 determines the mutual disengagement of the first and second graspingmembers partition 17 in the first position as shown infigure 5 . - The rotation of the
loading tank 5 towards the closure position drops thewaste 7 onto thefirst portion 11 of thetransfer chute 10. Thewaste 7 descends along thechute 10 but, before having completely passed thefirst portion 11, thepartition 17 has already repositioned in the first position. The fall of thewaste 7 into thecollection compartment 14 is consequently intercepted by thepresser 13, which in the meantime has returned to its rest position. Therefore, thewaste 7 is still engaged between thepartition 17 and thepresser 13. -
Figure 6 shows thecompactor device 1 when a user activates the pedal 21 again to introduce anew waste 7 into theloading tank 5. When thepedal 21 is actuated again, the lowering of thepresser 13 towards the operating position causes the previously introducedwaste 7 to be pressed against thepartition 17. Thestep 18 arranged between theupper portion 11 and thelower portion 12 of thetransfer chute 10 facilitates the effective retention of thewaste 7, preventing it from rising up along thetransfer slide 10 during the crushing step. - As can be seen in
figure 6 , when the pedal 21 released by the user goes back to the elevated position, the resultant translation of thepartition 17 towards the second position facilitates the fall of the crushedwaste 7 into thecollection container 15. At the same time, the repositioning of theloading tank 5 in the closure position releases thenew waste 7 onto theupper portion 11 of thetransfer chute 10. - The
new waste 7 descends along thetransfer chute 10 and will be stopped between thepresser 13 relocated in the operative position and thepartition 17 relocated in the first position, again arranging thecompactor device 1 in the condition offigure 5 for the execution of further operating cycles. - In the illustrated example, the
compactor device 1 is designed for the collection of plastic bottles, and the sizes of its components are studied for the purpose of the treatment of this waste type. - In order to avoid jams due to the introduction of relatively small foreign bodies, it can advantageously be provided that between the
presser 13 in the rest position and thelower part 12 of thetransfer chute 10, i.e., between thepresser 13 and thepartition 17 in the first position, a discharge port L is defined. The discharge port L has a greater amplitude than the minimum size detectable on thewaste 7 to be disposed into thecompactor device 1. It is thereby prevented that thenon-crushed waste 7 may fall into thecollection compartment 14. However, the discharge port L is large enough to permit the passage of smaller bodies, such as pieces of wood, stones or other objects other than those whose collection thecompactor device 1 is designed for. - In order to avoid permanent jams of the compactor device due to the introduction of full and closed bottles, and/or foreign bodies of sizes comparable to those of
waste 7, an unlockingmechanism 39 which can be activated by the user is also preferably provided, to determine the sliding of thepartition 17 towards the second position independently of the actuation of thepresser 13 and/or other members of thecompactor device 1. Preferably, therelease mechanism 39 comprises anauxiliary lever 40 which can be activated by means of arespective release pedal 41, for controlling the movement of thepartition 17 by means of at least one respectiveauxiliary tie rod 42. - In the illustrated example, an
auxiliary opening 43 is arranged on thefront wall 4 for introducing caps or other closure elements previously removed from thebottles 7 to facilitate their crushing. Downstream of theauxiliary opening 43, the caps may be conveyed to an auxiliary container, not shown. - The
compactor device 1 may also be provided with a user identification system by reading IRFD cards or other type of code, e.g., through aspecial reader 44 and a printing unit housed in the containment structure to issue through aslit 45 receipts attesting the use of thecompactor device 1. Thereader 44 and the printer may be powered by batteries which may be recharged, if needed, using photovoltaic panels, without no need of connections to power supply networks.
