Figure 10 shows a cross-sectional view of a hubcap along the plane B-B of Figure 9, Figure 11 shows a hubcap and two rubbish bins located therein,

Figure 12 shows the garbage cans of Figure 11 held by a grip unit to the hubcap. Preferred embodiment

The previous Figures do not show the collection container at scale, but only serve to illustrate the structural solutions and operation of the preferred embodiment. Here, the respective structural parts shown in the Figures and marked with reference numbers correspond to the structural solutions set forth in the following description and in which their reference numbers are assigned.

The Figures show a collection container 1 and its structural element in a garbage collection vehicle, which generally comprises a chassis and the driver's cabin that are not shown therein. The Figures show a collection container or a part thereof, in which collected garbage is transported, from a collection site, to a processing plant or to a landfill. In the present case, the collection container is divided into three adjacent chambers 2, 3 and 4, with vertical separation walls 5 and 6 extending in the longitudinal direction of the garbage collection vehicle. The number and width of the cameras can vary, obviously, depending on the type of waste to be transported in the vehicle. The number of cameras is at least three. The rear end of the collection container is open to provide cargo openings and emptying each chamber.

In order to load garbage into the collection container 1, the garbage collection vehicle is behind the container with rear doors 7, 8 and 9, often referred to as compactors, the number of which corresponds to the number of cameras in the collection container. The present embodiment has three cameras 2, 3 and 4, and three rear doors. Each of the rear doors has a hopper 10, 11 and 12 in front of the chamber, according to Figure 4, for example, to receive the collected garbage. Each tailgate also has a packing knife 13 known per se and which can be moved by means of a hydraulic device, which moves along the bottom of the hopper and drives the garbage into the loading and emptying opening. The packing blade can be partially seen in Figures 8 and 10. Each tailgate is arranged to be able to rotate about a rotation axis at the edge of the loading and emptying opening. In the present embodiment, the two external rear gates 2 and 3 can rotate around a substantially vertical axis 14 and 15, while the center can rotate around a horizontal axis 16.

Both the collection container and the tailgate have a conventional structure, so they are not described in more detail herein.

To load the garbage collection container 1, the garbage collection vehicle comprises an elevator tube 17, by means of which garbage cans 18 can be tipped over the hopper 10, 11 and 12 of the tailgate 7, 8 and 9. To do this , the hubcap has an essentially U-shaped support arm 19 which is preferably articulated on the collection container of the garbage collection vehicle. See Figures 2 and 8, for example. The support arm comprises at least two substantially parallel levers 20 extending from articulated fasteners 21 of the collection container backwards starting from the rear part of the collection container. A crossbar 22 is articulated on the levers and, in the operating position of the garbage collection vehicle, will be in a substantially vertical position. The crossbar comprises a frame 23 equipped with at least two grip units 24 that can be moved along the frame and are configured to be able to maneuver independently. With these grab units, the support arm is configured to grab the elevation mounts of a garbage can 18 that has been taken near the garbage collection vehicle, to raise and / or flip the garbage can with respect to the collection container substantially vertically and to empty it in the appropriate hopper. The support arm is operated with at least one maneuvering device that is a pneumatic or hydraulic cylinder 25, for example.

To allow the opening of one or several central rear doors 9, the support arm 19 is configured to rotate about a horizontal axis above said rear gate. The collection container according to Figure 3 has at least two parallel oscillating arms 26 that are fixed at their upper ends to pivots 27 above the central rear gates and at their lower ends are configured to carry the hubcap. When a central tailgate has to be opened, the swinging arms are rotated to move the hubcap to a position outside the conveyor belt for garbage that is stranded from the chamber. To allow the oscillating movement of the oscillating arms, the collection container has a passage between adjacent rear gates. When the hub lift has reached its final position, the central rear doors can be lifted to allow emptying of the cameras behind.

If the collection container 1 has three rear doors 7, 8 and 9, said swing arms 26 may preferably be part of the central rear tailgate and its frame. In this way, the tailgate 9 and the hubcap 17 will have a common axis of rotation and will simultaneously rotate to a position above the collection container, in order to allow emptying of the chamber 4 behind the tailgate.

The support arm 19 of the above-mentioned hubcap 17 has readers 28, see Figures 6 and 8, which detect the position of a garbage can 18 that has been taken to the hubcap. A reader according to the Figures comprises a mechanical latch that works in combination with an electric controller, but the reader can also be an optical or electronic device. As soon as the garbage container has acted on the reader, the appropriate grip unit moves in order to, in cooperation with a stop 29 on the crossbar 22, place the garbage can in a substantially stationary position on the arm of support by pressing the lifting mounts of the garbage can against the top of the crossbar.

The grip unit 24 is preferably arranged in the frame 23 of the crossbar 22 with glues 30, for example, according to Figures 5 and 6. These glues control the movement of the grip units in a substantially vertical direction. The maneuvering device 31 shown partially in Figures 6 and 7 handles the gripping units. The maneuvering device comprises pneumatic or hydraulic cylinders, for example, or electric spindle motors that work in combination with said readers 28 that start the manipulation device with a control signal. The gripping units preferably have a cam-like structure 32 at their edges facing the stop 29 of the crossbar 22. This cam-like shape facilitates cooperation with garbage cans 18 having different widths.

Since the grip units 24 cooperate with said readers 28, a limited number of units are always moved at the same time to grab a trash can 18. Thanks to this feature, it is possible to place one or more garbage cans next to each other in the elevator 17. When the first garbage can has been arranged in the crossbar 22, the next garbage can can be moved to the crossbar , after which the readers control the following grip units to make them work. In this way, it is possible to place a garbage can simultaneously for each chamber in the elevator, and considerably accelerate the handling of garbage cans during garbage collection. It is also possible to place rubbish bins next to each other that have different widths and shapes, as readers separately activate the required number of grab units for each garbage can.

It is even possible to equip the reader 28 with a counter that allows to record the number of garbage cans emptied in each hopper during the day. You can calculate as! the number of garbage cans emptied in each chamber during the day.

In a solution of the present embodiment, the collection container 1 has three chambers 2, 3 and 4 with the corresponding three rear gates 7, 8 and 9 and hoppers 10, 11 and 12. The support arm 19 articulated to the collection container and its crossbar 22 has three rectangular and disc-shaped gripping units 24 arranged in the frame 23 of the crossbar through glues 30 arranged in pairs to form the vertical edges of the gripping units. The grip unit has on its upper edge a cam-like structure 32, while its lower edge has a disposition 33 that absorbs shocks.

The maneuvering device 31 handles each grip unit 24 imparting it a movement that essentially coincides with the surface of the frame 23 of the crossbar. The movement extends from the stop 29 of the crossbar to a distance of 100 to 150 mm thereof, for example, in order to provide sufficient space to move the lifting mounts of the garbage can 18 towards the frame of the crossbar Preferably, each grip unit is equipped with said readers 28 to react when a trash can is moved nearby. Readers who are affected by the placement of the garbage can against the crossbar cause the corresponding grab unit to move, thereby pressing the garbage can against the stop of the crossbar. The process is illustrated, for example, in Figures 9 to 12. This process can be repeated as long as there is room for a garbage can in the elevator, or until the contents of the garbage container correspond to the garbage that is collected in the Camera still free.

The above description and related Figures are only intended to illustrate the present solution for the construction of a collection container. Therefore, the solution is not merely limited to the embodiments described above, but within the idea described in the appended claims a plurality of alternative variations or embodiments are feasible.
