This invention relates to a refuse collection system and more specifically to a refuse collection system utilizing collection trucks with removable bodies.
BACKGROUND OF THE INVENTIONIn the refuse collection industry, a large variety of different trucks are used to travel door-to-door for the collection and ultimate disposal at a refuse site. In recent years there has been a tendency toward increasing the size of the collection trucks so that the trucks could stay on a route longer without having to travel to the disposal site so often. Further, increase in size and therefore payload has been needed because disposal sites have become fewer and further apart in response to regulatory requirements, and therefore hauls of longer and higher payloads are needed.
Because of this increase in size and consequently the weight, there is a substantial increase in the cost of the collection trucks and in maintenance. By increasing the size, fewer trucks are used, to reduce costs, and, thus, any downtime or maintenance cuts into the operating fleet to a greater extent. Also, the need to travel to and from disposal sites reduces actual collection time. Further, because of the increased size, maneuverability is reduced and it is more difficult for drivers to access small alleys, cul de sacs, and other physically restricted areas in which refuse containers are most likely to be situated. Thus, the increased size can further increase collection time and, therefore, costs.
It would be highly advantageous, therefore, to remedy the foregoing and other deficiencies inherent in the prior art.
Accordingly, it is an object of the present invention to provide a new and improved refuse collection system and method of operation.
Another object of the invention is to provide a new and improved refuse collection system that is easier to manufacture and maintain.
And another object of the invention is to provide a new and improved refuse collection system that is less expensive to manufacture and operate.
Still another object of the present invention is to provide a new and improved refuse collection system that includes more maneuverable collection trucks.
A further object of the present invention is to provide a new and improved refuse collection system including detachable truck bodies or refuse containers that greatly simplify manufacturing, operation, and maintenance.
A further object of the present invention is to provide a new and improved hauling method whereby the maximum loads permitted on the highways may be hauled.
A still further object of the present invention is to provide a new and improved flexible system where hauling can be scheduled at convenient times for hauling and collection can be independently scheduled at convenient times for collecting.
SUMMARY OF THE INVENTIONBriefly, to achieve the desired objects of the instant invention in accordance with a preferred embodiment thereof, provided is a refuse disposal system including a refuse collection truck with a chassis and a hopper for receiving refuse and the hopper includes a packer. A body has a bottom, side walls, and a cover and an opening in the front wall to receive refuse from the hopper. The chassis includes detachment and manipulation apparatus with the hopper being mounted on the detachment and manipulation apparatus and the body being detachably mounted on the detachment and manipulation apparatus so that the opening is in communication with the hopper for receiving refuse therefrom with the body in a collecting position. The detachment and manipulation apparatus is designed to move the body from the collecting position to a hauling position and to detach the body in the hauling position. In this specific embodiment, packer reciprocating apparatus is included for reciprocating the packer within the hopper to move refuse from the hopper into the body through the opening with the body in the collecting position, although other packer apparatus (e.g. a swinging platen) could be used.
From the disclosure, it will be understood that the collecting truck is capable of moving full bodies from the attached collecting position to a detached hauling position at a body receiving station, which can be the ground, a haul vehicle, or any intermediate location. Further, the collecting truck can also pick up empty bodies from the body receiving station, moving the bodies from the detached hauling position at the body receiving station to an attached collecting position on the collecting truck.
To further achieve the desired objects of the instant invention in accordance with a preferred embodiment thereof, a haul vehicle is provided including an elongated chassis with wheels attached thereto. A plurality of body receiving frames are transversely mounted on the chassis with each body receiving frame being positioned to receive a body from a refuse collecting truck when the collecting truck is moved to a position adjacent the haul vehicle. Each body receiving frame of the plurality of body receiving frames includes transversely extending support members affixed to the chassis and a lifting frame pivotally attached to the support members with the lifting frame further including attachment apparatus to detachably couple bodies to the lifting frame. Each body receiving frame of the plurality of body receiving frames includes a hydraulic cylinder coupled between the lifting frame and the transversely extending support members for moving the lifting frame between a horizontal body receiving position and a raised body dumping position.
A preferred method, of disposing of refuse in accordance with the present invention includes the steps of providing a relatively small collection truck including a chassis and a first detachable body attached to the chassis; filling the first detachable body with refuse; providing a relatively large haul vehicle designed to receive a plurality of detachable bodies thereon; using the collection truck, moving the filled first detachable body to the haul vehicle, placing the filled first detachable body on the haul vehicle, and detaching the first detachable body from the collection vehicle and attaching the first detachable body to the haul vehicle; moving the collection vehicle to an empty second detachable body attached to the haul vehicle, detaching the second detachable body from the haul vehicle and attaching the second detachable body to the collection truck; and filling the second detachable body with refuse. The process is continued until all of the available detachable bodies are filled or until the refuse in that specific area is collected.
It is anticipated that in at least some instances the haul vehicle will be a trailer. Further, in some systems or methods of operation, the haul vehicle with a plurality of empty bodies thereon might be hauled by the collection truck, using an appropriate converter dolly adapter, to the collection site. The collection process is performed by the collection truck until the some or all of the empty bodies are filled and reassembled on the haul vehicle. The haul vehicle can then be hauled to a disposal site by a larger tractor normally assigned to several haul vehicles.

Downwardly extending struts 70 are attached midway along the length of chassis frame 60 at opposite sides thereof to horizontally mount an axle 72 under chassis frame 60. A hydraulic cylinder 74 has one end attached to axle 72 and the opposite end attached to a pivot plate 75 at the front end of hoist frame 62. It will of course be understood that a pair of hydraulic cylinders 74 could optionally be used on either side of chassis frame 60, as illustrated in
Referring again to
The forward ends of the elongated side members of slide frame 64 are formed in an upwardly offset configuration and bottom 38 of hopper 16 is affixed thereto so as to be vertically offset slightly above the remainder of the elongated side members. Slide frame 64 also includes a pair of cross-member plates 82 and 84 spaced apart along the length thereof. Each cross member plate 82 and 84 has a central portion that extends slightly above the upper surfaces of the elongated side members of slide frame 64 and the elongated side members of hoist frame 62 to aid in supporting body 14 thereon.
Body 14 is provided with a pair of elongated, spaced apart runner-like members 86 that extend along the lower surface and up the rear side (see FIGS, 1 and 6). With body 14 correctly positioned on slide frame 64, runner-like members 86 (on the lower surface) are slideably positioned on the upper surface of cross member plates 82 and 84. When body 14 is moved to a haul vehicle (described in detail below) runner-like members 86 on the rear surface are slideably positioned on the haul vehicle.

In the disclosed collection system, haul vehicle 100 can be designed to carry, for example, five bodies 14 with the number of bodies depending upon the specific system or application. While designing trailer 104 to carry five bodies 14 results in a haul vehicle length approximately equal to a standard semi truck, it will be understood that a haul vehicle can be designed to carry substantially any desired number of bodies 14. In practice, it is contemplated that haul vehicle 100 could include trailer 104, which attaches directly to tractor 102, and/or one or more trailers 106, as illustrated in
Here it should be understood that as a part of the collection process, either trailer 104 or trailer 106, containing a plurality of empty bodies (i.e. body 14) thereon, is towed to the intermediate point in the collection area. To perform this part of the process, haul vehicle 100 could be driven to the intermediate point and simply parked as the collection process proceeds. In a more efficient procedure, tractor 102 could tow trailer 104 to the intermediate point, unhook trailer 104, and proceed to tow other trailers to other intermediate points. Alternatively, collection truck 10 could tow trailer 106 with empty bodies thereon to the intermediate point, complete the collection process, and a larger tractor, e.g. tractor 102 could come to tow trailer 106, with filled bodies 14 thereon, to the disposal area. To aid in coupling trailer 106 to collection truck 10, a wheeled connection dolly 107, similar to that illustrated in
As can be seen in FIGS. 12 or 13, haul vehicle 100 or 106 includes a plurality of body receiving frames 110 spaced therealong. Body receiving frames 110, as will be explained in more detail presently, extend generally transverse to the longitudinal axis of haul vehicle 100 or 106 and each body receiving frame 110 is designed to have a body 14 detachably positioned thereon. As stated above, the operator of collection truck 10 drives to a position adjacent haul vehicle 100 or 106 for detaching and transfer of the full body 14 from collection truck 10 to the haul vehicle. Similarly, the operator drives to a position adjacent haul vehicle 100 or 106 for transfer and attaching of an empty body 14 from the haul vehicle to collection truck 10.

Lifting frame 120 includes a pair of transversely extending support members 124 affixed together by cross-pieces 126 and 128. Support members 124 are spaced apart such that in the horizontal position they are positioned between and parallel with support members 114 and the ends, which are positioned in the yokes formed by blocks 118, are bored so that pivot pins 122 extend therethrough and pivotally mount lifting frame 120 for movement between the horizontal position and a vertically raised position. A pair of lifting hydraulic cylinders 130 is provided with one end of each being attached by a pair of yokes 132 to chassis 112 and the other ends attached to cross-piece 128 by yokes 134 formed therewith. Activation of hydraulic cylinders 130 moves lifting frame 120 between the horizontal and the vertically raised positions, as illustrated in
Four attaching pins 140 are affixed to the inner surfaces of support members 124 so as to extend inwardly therefrom. Attaching pins 140 are positioned to be engaged by the four hooks 90 on the rear wall of body 14 (best seen in

While the embodiments illustrated include a body with an opening in the front wall and a cover on the top, it will be understood that other structures might be utilized in specific applications. For example, in some applications it may be desirable to have the option to dump refuse from the body directly from the collection truck. This may be especially true under certain circumstances, e.g. breakdowns or maintenance problems in either the collection truck of the hauling vehicle. However, in the embodiment illustrated, the detachment and manipulation apparatus rotates the body ninety degrees, which is sufficient to bring the cover and top opening into a vertical position but is not sufficient for convenient and complete dumping of refuse from the body. Thus it may be convenient to provide the primary cover and dumping opening in the top and/or a second cover and dumping opening in the back wall or in one of the side walls.
Also, in the embodiment illustrated, the body is rotated ninety degrees as it is positioned on a haul vehicle. However, it will be understood that in some applications it may be convenient to simply slide the body rearward or sideways onto a haul vehicle. With only slight modifications to the detachment and manipulation apparatus, the body could be rotated (as shown) and/or slid rearward or sideways to move it from the collection position to a hauling position and to detach the body. Also, in such systems the additional or differently positioned cover and dumping opening might be used in place of the cover illustrated.
Thus, a new and improved refuse collection system and method of operation are disclosed. The new and improved refuse collection system is easier and less expensive to manufacture, maintain and operate. Also, the new and improved refuse collection system includes more maneuverable collection trucks that can easily gain access to and maneuver in close or small alleys and other physically restricted areas in which refuse containers are most likely to be situated. From the above description it will be understood by those skilled in the art that the detachable bodies, collection trucks and hauling vehicles can be provided in a variety of different configurations but the disclosed body, collection truck and hauling vehicles are preferred because of the disclosed advantages in operation. For example, in some instances it may be convenient to slide the body rearwardly or sideways to the haul vehicle.
Various changes and modifications to the embodiment herein chosen for purposes of illustration will readily occur to those skilled in the art. To the extent that such modifications and variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof which is assessed only by a fair interpretation of the following claims.
