Description

MATERIAL COLLECTION BODY

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority of Canadian patent application No. 2,723,603 filed on November 25, 2010, the specification of which is hereby incorporated by reference.

BACKGROUND

(a) Field

[0002] The subject matter disclosed generally relates to a vehicle for the collection, the transportation and the compaction of materials.

(b) Related Prior Art

[0003] At this point, different types of collection bins allow the collection, the transportation and the compaction of recyclable or non-recyclable materials. In general, these bins include a cargo bed of prismatic shape and three loading options: 1 ) opening allowing lateral loading, 2) opening allowing rear loading, and 3) opening allowing front loading. Typically, these bins also allow a mechanism for loading and discharging of containers to the inside of the waste bin collection. These bins are also equipped with a press mechanism for the compaction of refuse and waste, allowing them to be ejected out of the dumpster.

[0004] In addition, the bins for collection and compaction of waste material currently have the option to allow the loading of waste material through smaller containers parked in the streets. This specific function allows the lifting and unloading of the recyclable and non-recyclable materials in a proper compartment of the cargo bed.

[0005] In fact, after the analysis of the different models of bins for collection and compaction of waste materials, it is possible to identify several areas that could be significantly improved. First, recycled or non-recycled materials, which are collected in the municipalities, are most of the time excessively heavy. Hence, the forces applied on the waste body by the waste materials falling from a waste bin during collection, but also the forces applied on the bin during the compaction of the waste materials, increase obviously the damage on the main equipment. To compensate for this deficiency, the waste collection equipments of the prior art are mostly built from strong and very heavy materials, which greatly increases the total weight of the waste material collection bin. Such an increase in the total mass of the vehicle results in an increase of the fuel consumption of the vehicle and in a reduction of the payload.

[0006] On the other hand, after analyzing the different models of collection and compaction waste material bins, there is shown in the prior art compaction mechanisms using a large hydraulic power supply given a limited volume of the bin which requires a greater compaction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] Referring now to the drawings, and more particularly to Fig. 1A, 1 B and 2, the collection body 30 is of a cylindrical shape and is provided with an articulated arm 40 for transporting a material container 35 to the collection body 30. The collection body 30 is disposed with well known techniques on the chassis 31 of a vehicle. As shown in Fig. 2, the collection body 30 may include an upper wall 32 and a lower wall 34. The collection body 30, illustrated as being cylindrical on Fig. 1A, 1 B and 2, may be made, without limitations, of steel, aluminum, or any suitable materials as it is well known by those skilled in the art.

[0039] The articulated arm 40 of the collection body 30 is fixed to be deployed from a closed position, illustrated in Figure 1A, to a position for capturing a container, illustrated in Figure 1 B, to a discharge position, illustrated in Figure 2, to allow the passage of materials from the material container 35 to the collection body 30 through the opening 50 (Fig. 3) for unloading or discharging materials into the collection body 30. As shown in Figure 2, the articulated arm 40 matches intimately, although this is not absolutely essential, with the cylindrical portion of the collection body 30. Obviously, the three positions of the articulated arm 40, illustrated in Figures 1A, 1 B and 2, correspond to useful positions. When the articulated arm 40 is completely at a resting position, the articulated arm 40 is completely folded over the support 25, as shown in Figure 1A. The positioning of the support 25 of the articulated arm 40, which is under the chassis 31 of the vehicle, prevents from the sway of the vehicle and the collection body 30 during the operation.

[0040] Still referring to Figures 1 A, B and 2, there is shown the articulated arm 40. More specifically, the articulated arm 40 may include a triangular member 41 on a support 25, as shown in Figures 1 B and 2, and a slightly curved link 43, attached to a hooking member 44, which is intended to capture the material container 35. It will be expected that the curvature of the curved link 43 is obviously intended to match closely along the outer wall of the cylindrical collection body 30, as it is clearly shown in Figure 2 in a discharging position.

[0041] Referring now to Figure 3, the collection body 30 may include a material tamping mechanism 51 and a material packing mechanism 52, which will now be described in details. As shown in Figures 1A, 1 B and 2, the collection body 30 is of a cylindrical shape, but it is understood that those skilled in the art may adapt the tamping and the packing mechanisms 51 and 52 to any other forms, including prismatic, elliptical and the like. As shown in Figure 3, the materials are discharged through the opening 50, located on the upper wall 32 of the collection body 30 and more specifically, the opening 50 may be located on the front side of the collection body 30. The opening 50 may also be located at various locations between the upper wall 32 and the lower wall 34 as at the back side, on top or side of the collection body 30.

[0042] To avoid excessive forces associated with the materials falling on the lower wall 34 of the collection body 30, there is provided a receiving plate 56, which is an horizontal plate for receiving materials discharged from the material container 35 via the opening 50 of the collection body 30 (Fig. 3).

[0043] As shown in Figure 3, the fixed receiving plate 56 may be positioned between the upper wall 32 and the lower wall 34. The tamping mechanism 51 will now be described in details. Referring to Figure 5, the tamping mechanism 51 includes a tamping ram 55 and a bearing seat 60, arranged to move back and forth on the material receiving plate 56 (Fig. 3). For a preferred embodiment, although this is not essential, the tamping ram 55 is semicircular as shown in Figure 5, and includes a vertical upper portion 57 and a lower portion 58, which is slightly forwardly inclined, as can shown in both Figures 3 and 4. In this sense, tamping materials beyond the receiving plate 56 is preferably realized with the tamping ram 55 as shown in Figure 4. However, those skilled in the art can obviously conceive any other structure tamping ram 55, without departing from the scope of the present invention.

[0044] On the basis of bearing seats 60, it moves on the axial rollers 75, mounted with well-known techniques, and more details will be later available in this description.

[0045] On the other hand, Figure 3 illustrates a packing mechanism 52. Indeed, when the materials have been packed on the lower wall 34 of the collection body 30 by the tamping mechanism 51 , the packing mechanism 52 will compress those materials. [0046] The packing mechanism 52 may include a packing ram 65 and the bearing seats 70 (Fig. 6). The packing ram 65 must be able to move back and forth along the lower wall 34 of the collection body 30, as it will be shown later.

[0047] Particularly referring to Figures 3, 4 and 6, it will be shown that because of the cylindrical structure of the collection body 30, the packing ram 65 is of a generally semi-circular shape (Fig. 6). Referring to Figure 6, the packing ram 65 has a top horizontal plate 81 , a vertical shielding plate 85, as well as axial rollers 76, allowing movement of the packing ram 65 along the lower wall 34 of the collection body 30. There is provided a top horizontal plate 81 to avoid the materials, when in the tamping mechanism 51 and in the packing mechanism simultaneously, to fall behind the packing ram 65. In addition, scrappers or a sealing joint 80 are also installed in the interstices between the different parts.

[0048] As regards to the movement of the packing mechanism 52, reference is primarily made to Figures 3 and 4, and to Figure 7 for the internal guides 95 of the packing mechanism 52, which are not shown in Figures 3 and 4.

[0049] To ensure efficient movement of the tamping mechanism 51 and the packing mechanism 52, along a portion of the receiving plate 56 and the lower wall 34 of the collection body 30, there is provided internal guides 90 for the tamping mechanism 51 , and more particularly for the tamping ram 55.There is also provided internal guides 95 for the packing mechanism 52, and more particularly for the packing ram 65, as it is shown in Figure 7. Still referring to Figure 7, it is shown that the internal guides 90 may be U-shaped and directed both inward for forming the rails. On the other hand, the internal guides 95, by their location on the lower wall 34 of the collection body 30, have a particular structure illustrated in Figure 7. Of course, this structure may vary depending on the choice of those skilled in the art, and will obviously be part of the present invention. [0050] In operation, as an example, the tamping mechanism 51 is activated as required for each material discharge through the opening 50. The tamping of material by tamping ram 55 is effected by rolling through the axial rollers 75 in the internal guides 90 allowing the optimization of the translational motion. The two rams 55 and 65 move by rolling rather than by friction, as in the prior art, thereby reducing friction.

[0051] Having firstly a tamping mechanism 51 minimizes the use of the packing mechanism 52. This reduces the demand on the operation of an hydraulic equipment to avoid the unnecessary stress on the structure, the unnecessary expenditure of energy and thereby, the amount of discharge of carbon dioxide in the air.

[0052] On the other hand, as shown in Figure 3, the packing mechanism 52 is at a resting position under the receiving plate 56, allowing the reception of materials. More particularly, the packing mechanism 52 is activated as required, for example, every five cycles processed by the tamping mechanism 51. The packing of material by the packing ram 65 is effected by rolling the packing mechanism through the axial rollers 76 in the internal guides 95 allowing an optimized translation movement.

[0053] In sum, referring to Figure 3, it is shown that, in general, the translational movement of the tamping ram 55 is possible using the internal guides 90, thus tamping the material into the collection body 30. On the other hand, the translational movement of the packing ram 65 is possible by using the internal guides 95, thus allowing the compaction of materials (Fig. 4). In addition, the receiving plate 56 may include openings holes behind the tamping ram 55, than avoiding the accumulation of materials behind the tamping ram 55, allowing a translation movement of materials, towards the lower wall 34 of the collection body 30 to the two cleaning doors 125. [0054] Referring now to Figure 8, there is shown the door 110 of the collection body 30 in the closed position. The door 110 still, may have the shape of a container that can contain materials. This feature adds to the volume of the collection body 30. As discussed in Figures 8 and 9, the opening and the closing of the door 110 is done in a manner known by those skilled in the art.

[0055] The collection body 30 may include an hydraulic reservoir 130 (Fig. 10) next to the collection body 30.

[0056] The cylindrical structure simplifies the construction of the collection body 30 and increases its effective volume, decreases the weight of the collection body 30 and thereby increases its payload. The cylindrical structure of the collection body 30 has a greater volume of cargo (42 cubic yards) over the prior art (37 cubic yards) to thereby reduce the rate of compaction necessary to achieve the permissible load. Having a larger volume requires less compaction to achieve the payload and allow more loading of low density materials difficult to compact.

[0057] Having a two stages packing mode including a tamping mechanism 51 and a packing mechanism 52 reduces the dimensions of the loading compartment for a greater payload volume and reduces the need for powerful compaction, resulting in energy savings. Furthermore, the tamping mechanism 51 and the packing mechanism 52 prevent the damages to the collection body 30 during the discharge of the materials and reduce the potential structural and mechanical failures.

[0058] While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
