Abstract

An improved waste collection system having an on-site container which is internally compartmented to receive and separately store the various waste components such as aluminum, glass, paper and land-fill trash. The route collection vehicle is divided into chambers and has a compaction system for compacting the contents of at least some of the collection vehicle chamber. The vehicle has a loading apparatus which lifts the container to an inverted dumping position in which position the container is positioned with respect to the chambers to cause the waste to be inherently separated or classified within the collection vehicle chambers. The loading apparatus may be side or front loading.

Claims

1. An improved waste collection system of the type for collection waste from on-site locations along a route and transporting the collected waste to a centralized dumping station, said system comprising:

(a) at least one on-site waste storage container having a bottom and an upstanding wall defining an interior including divider means forming at least two waste-receiving compartments therein each for receiving predetermined different types of waste, said compartments each having an openable cover moveable between an open and a closed position;

(b) a mobile waste collection device having upstanding side walls, said collection device having at least a partially open top defining a waste-receiving hopper for receiving waste emptied into said collection device, said collection device having divider means associated therewith separating the waste collection device into separate chambers each for temporary storage and transportation of predetermined different types of waste;

(c) loader means associated with said collection vehicle having container pick-up means for releasably holding said container and lift means for elevating said container from a lowered on-site location to a dump position in which the container is at least partially inverted over said hopper area; and

(d) said container in said dump position being positioned relative to said chambers to move said covers to an open position each adjacent a separate chamber to substantially cause the contents of the container compartments to be emptied into separate chambers of the waste collection device thereby segregating the waste into preselected types of waste in the collection operation.

2. The waste collection system of claim 1 wherein said openable covers are mounted on a common hinge and further including stop means associated with said covers to limit the arc of travel of said covers between said open and closed positions.

3. The waste collection system of claim 1 wherein said on-site containers are fabricated from a flexible material and are mounted on wheels.

4. The improved waste collection system of claim 1 further including indicia on the container to enable the user to determine the appropriate compartment in which to deposit various types of waste.

5. The waste collection system of claim 1 wherein said loader assembly includes (i) a vertical rail assembly;

(ii) a carriage assembly operatively coupled to said vertical rail assembly;

(iii) container pick-up means operatively mounted on said carriage assembly;

(iv) extension/retraction means for moving said pick-up means laterally with respect to said collection device; and

(v) drive means for moving said carriage means, pick-up means and extension/retraction means from said on-site position to said dump position.

6. The waste collection system of claim 5 wherein said drive means comprises an elongated drive chain in a drive chain track and including motor means for reversably driving said chain at a controlled rate.

7. The waste collection system of claim 1 wherein said compaction means comprises a compaction plate moveable within each of said compartments and hydraulic ram means operatively connected to said compaction plates.

8. The improved waste collection system of claim 1 wherein said waste chambers are pivotally mounted on a bed having front and rear ends and tilt means for selectively raising and lowering the chambers with respect to the bed to facilitate dumping of the contents of said unit.

9. The waste collection system of claim 8 wherein said waste collection device has opposite side walls, a front wall and a rear end wall and wherein said rear end wall is provided with latchable tailgate assemblies in association with each of said compartments.

10. The improved waste collection system of claim 9 wherein said loader is associated with a side wall of said waste collection device.
