- a lifting and upsetting device On a side of the vehicle, in proximity to the hopper, is mounted a lifting and upsetting device which is able to pick up from the ground a waste container to empty it above the hopper and subsequently place it back on the ground.
- the hopper is internally fitted with transfer means able to convey the waste selectively into the lower or upper compartment of the body according to the type of waste. More specifically, the conveyance of the waste into the lower compartment takes place thanks to a first thruster element movable on the bottom of the hopper towards the first opening ending in the lower compartment itself.
- a movable bottom located immediately above the space dedicated to the motion of the first thruster is distended.
- the waste of the second type therefore falls on the movable bottom to be conveyed into the upper compartment through the action of a second thruster movable on the movable bottom itself towards the respective top opening.
- the second waste destined to be sent into the upper compartment, to be withheld in the container by means of an auxiliary lid while the first waste is emptied and until its level in the hopper has been lowered sufficiently to allow the movable bottom to be distended.
- the object of the present invention is to overcome the problems of the prior art, realising a device able simultaneously to empty different types of waste from the same container, as well as to position the waste itself in respective compartments provided in the body of a vehicle, without thereby entailing any risk of mixing between different types of waste.
- Another object of the invention is for such device to retain the ability to empty indifferently single-material and multi-material containers.
- the number 1 indicates in its entirety a device for the reception and selective transfer of waste emptied from a container, for vehicles used for the differentiated collection of waste, according to the present invention.
- the device 1 is suitable for being associated to a vehicle 2 used for waste collection, comprising a driver's cab 3 and a holding body 4 internally subdivided into a lower compartment 4a and an upper compartment 4b respectively used to receive a first and a second type of waste, respectively indicated as "A" and "B” in Figure 1.

- the bottom wall is translated to the closed position, whereupon the dividing baffle 21 is brought to the open condition by lifting the closure portion 25.
- the shutter 15b is raised and the upper thruster 14 is activated to thrust the waste of the second type along the movable bottom wall 16 thereby to transfer it into the upper compartment 4b through the upper opening i5.
- the closure means associated to the dividing baffle 21 comprise the upper thruster 14 itself, as described above, the waste of the second type emptied into the second collection chamber 5b is initially accumulated above the thruster itself, placed in the intermediate position of collimation with the dividing baffle 21.
- the waste contained in the second collection chamber 5b will be let fall thereon as a result of a translation of the upper thruster 14 away from the rear wall 13 of the hopper 5, to allow the waste itself to be transferred into the upper compartment 4b in a manner identical to the one described above.
- the device according to the invention is able to convey the entire quantity of waste emptied from the container 7 exclusively into the lower compartment 4a or into the upper compartment 4b, in such a way as to manage also emptying containers containing exclusively materials of one or of the other type.
- the container 7 containing exclusively material of the first type, whether the dividing wall 27 is present or not, is emptied maintaining the shutter element 15b in closure condition and setting the dividing baffle 21 into the open condition with the movable bottom wall also in open position.
- the dividing baffle can advantageously be hinged according to a horizontal axis X-X ( Figure 8) between the side walls 24 of the hopper 5 in such a way as to be able to be oriented, by the action of an orienting actuator 31, around its own hinge axis X-X.
- the dividing baffle 21 is able to be selectively oriented between a position of normal utilisation, wherein it is vertically positioned to collimate by means of its own upper edge 21b with the dividing wall 27 of the container 7, and a first deviated position wherein, as shown in Figure 5, it is able directly to channel towards the first collection chamber 5a the entire quantity of waste emptied from the container 7.
- the upper terminal edge 21b of the baffle 21 can conveniently be obtained on an upper extensible portion of the dividing baffle itself, slidingly engaged to the aforementioned main portion 23.
- One or more extension actuators 33 are activated concurrently with the orientation of the dividing baffle 21 in the deviated position, to place the upper extensible portion 32 in an extended condition wherein the upper terminal edge 21b is moved away from the oscillation axis X-X to protrude laterally with respect to the vertical projection of a side wall of the container, as Figure 5 clearly shows.
- the upper thruster can be placed in the intermediate position, essentially in collimation with the lower edge 21a of the baffle 21, to prevent any back surge of material into the second chamber 5b.
- the subject device can advantageously be set as per Figure 6.
- the movable bottom wall 16 is set in closed condition and the shutter 15 is lifted into the open condition to clear access to the upper compartment 4b.
- the dividing baffle 21 is maintained in open condition to allow the passage of the upper thruster 14 underneath it.
- the dividing baffle 21, by the action of the orientation actuator 31, can advantageously be translated from the position of normal utilisation to a second deviated position wherein, as in Figure 7, it is able to convey exclusively into the second collection chamber 5b all the waste emptied from the container 7.
- the extensible portion 32 of the baffle 21 can be placed in distended condition similarly to the description provided with reference to Figure 5, to prevent part of the second waste from falling into the first chamber 5a.
- the invention thereby attains the proposed objects.
- the subject device allows simultaneously to empty two or more types of waste from a container inside the loading hopper, and is able automatically to manage the transfer of the wastes into one or the other compartment of the body of the vehicle.
- the invention therefore allows considerably to reduce the duration of the stops of the vehicle for the execution of the container emptying cycle.
- the duration of each stop is linked to the time strictly necessary to bring the container to an upset position above the hopper and place it back on the ground after upsetting it, since the subsequent transfer of the wastes into the respective compartments of the body by the thrusters can be performed also with the vehicle in motion.
- the subject device further retains the advantage of being able indifferently to operate also on single-material containers, be they fitted with an internal dividing wall or not, to the advantage of the flexibility of utilisation of the vehicle.
- the device according to the invention can also be adapted to operate on more than two types of waste, providing a suitable number of dividing baffles, as well as movable bottom walls and respective compacting means operating at different levels in the hopper, to transfer the waste into respective compartments of the body
