Abstract

A system includes a point-of-use container having a plurality of removable bins with each bin for a different recyclable material. A pickup container, transportable to a pickup location, has a plurality of bins corresponding to the point-of-use bins, each bin having a normally closed hinged lid. A truck body has a set of bins corresponding to the pickup container bins and an automated arm mechanism for holding the lids closed, and for picking up and inverting the pickup container over the truck body bins. A computer is programmed to control the arm mechanism to perform the required movements. A barcode on the pickup container is read and each lid is released selectively when each bin is over a corresponding truck body bin to dump the contents of the container bins. The container is returned to its pickup location and released.

h) control means for controlling said pickup arm assembly to engage and release said container means, and for controlling said track moving means, to lift and invert said container means over said truck body, to selectively operate said carriage means to successively move said inverted container means over each of said second bins, and to selectively release each of said closed lids over a respective one of said second bins corresponding to the materials in said closed bins.

2. The system as defined in claim 1 in which said container engaging means and said pickup arm supporting means include first actuator means for moving said pickup arm assembly inward and outward with respect to said carriage, second actuator means for moving said container engaging means, and a plurality of third actuator means mounted on said container engaging means for holding said bin lids closed, and thereafter selectively releasing said bin lids.

3. The system as defined in claim 1 in which said container engaging means includes a pair of clamping arms mounted to said assembly and adapted to move toward and away from each other, said clamping arms movable to clamp said container means therebetween preparatory to lifting of said container means.

4. The system as defined in claim 1 in which said control means is manually operated.

5. The system as defined in claim 1 in which said control means includes:

a computer; and

a computer program for said computer, said program for causing said pickup arm assembly to perform movements necessary to clamp said container means, for causing said carriage means, said pickup arm assembly supporting means, and said track to pick up and invert said container means, to move said container means successively over each of said second bins, and to selectively release each of said lids.

6. The system as defined in claim 5 in which said control means includes a manual control input for permitting operator intervention and control of said pickup arm assembly, said track, and said carriage means.

7. The system as defined in claim 5 in which said control means includes:

first machine readable indicia attached to said container means, said indicia indicative of the materials to be deposited in each of said first bins;

indicia reading means attached to said pickup arm assembly for reading said first indicia after clamping of said container means; and

said lid release control means for selectively releasing each of said lids in accordance with said first indicia.

8. The system as defined in claim 7 in which said control means further includes:

second machine readable indicia attached to said container means, said second indicia indicative of an identity of an entity to be billed for collection of said materials; and

said indicia reading means includes means for reading said second indicia after clamping of said container means.

9. The system as defined in claim 5 in which said computer program further controls said pickup arm assembly to return said container means to said pickup point, and to operate said clamping arms to release said container means, and to thereafter fold said pickup arm assembly adjacent said truck body.

10. The system as defined in claim 7 in which said machine readable indicia is a barcode.

11. An automated trash collection system for recyclable materials comprising:

a) an outdoor container having

i) a plurality of first bins marked to selectively receive materials,

ii) each of said first bins having a lid hingedly attached thereto,

b) a truck body, for mounting to a truck, having

i) a horizontally disposed track pivotally attached at each end to a pair of telescoping arms, said arms pivotally attached to a front and back end of said truck body, and means for extending and retracting said telescoping arms, and means for moving said track from a position near ground level to a position over said truck body,

ii) a carriage mounted to said track, including means for moving said carriage along said track,

iii) a pickup arm assembly having scissor arms with proximal ends thereof attached to and extending at essentially right angles from said carriage, said pickup arm assembly including means for extending and retracting said scissor arms with respect to said truck body, and

iv) a plurality of second bins;

c) said pickup arm assembly having a pair of opposed clamping arms attached to a distal end of said scissor arms, said clamping arms including

i) means for moving said clamping arms alternately toward and away from each other,

ii) means mounted on said clamping arms for selectively clamping and releasing said bin lids; and

d) computer means including a computer program installed in said computer means, said program for controlling said track, said carriage, and said pickup arm assembly to move said clamping arms to a position to clamp said container therebetween, to pick up and invert said container over said second bins, to selectively move said carriage to place said container successively over each of said second bins, and to selectively release each of said first bin lids.

12. The system as defined in claim 11 in which said computer means includes manual control input for permitting operator intervention and control of said pickup arm assembly, said track and said carriage.

13. The system as defined in claim 11 in which opposing surfaces of said clamping arms each have a resilient pad attached thereto.

14. The system as defined in claim 11 which further includes:

a machine readable barcode disposed on an outer surface of said container, indicative of the contents of each of said first bins.

15. The system as defined in claim 14 which further includes a barcode reader mounted on said pickup arm assembly and connected to said computer means for reading and identifying the contents of each of said first bins.

16. The system as defined in claim 11 in which said computer program further controls said track, said carriage, and said pickup arm assembly to replace said container at said pickup location.
