Auto cycle swivel mounted container handling system
First Claim
1. A lift and dump mechanism to automatically lift, dump and return a container of interest to an original location comprising:
- a) a frame;
b) carrying mechanism for carrying the container between pick-up, dump, and release locations;
c) swivel mount mechanism attached between said frame and said carrying mechanism for swiveling said carrying mechanism fore and aft relative to said frame, said swivel mount mechanism having a first position sensor coupled thereto for generating a signal representative of a rotational position of said swivel mount mechanism relative to the frame;
d) reach mechanism pivotally attached to said swivel mount mechanism for extending the carrying mechanism towards and away from the frame, said reach mechanism having a second position sensor coupled thereto for generating a signal representative of a position of said reach mechanism relative to the frame;
e) lift mechanism pivotally attached between said reach mechanism and said carrying mechanism for lifting the container between the pick-up, dump, and release locations, said lift mechanism having a third position sensor coupled thereto for generating a signal representative of a position of said lift mechanism relative to the reach mechanism;
f) a control system for controlling the position of said swivel system, said reach mechanism, said carrying mechanism and said lift mechanism, said control system being electrically coupled to said first, second and third position sensors, said swivel mount mechanism, said reach mechanism, said carrying mechanism, and said lift mechanism; and
g) wherein said control system includes;
(1) a memory programmed to store values related to signals from said position sensors indicative of at least one coincident position of said swivel mount mechanism, said reach mechanism and said lift mechanism at said pick-up location;
(2) control device to reposition said swivel mount mechanism, said reach mechanism and said lift mechanism at said release location, said release location being at a height greater than that of said pick-up location.

Abstract
A refuse and/or collection vehicle having an automated container handling mechanism that may automatically lift and dump a container into a charging hopper of the vehicle. A microprocessor controls the extension and lift of the container handling mechanism and analyzes the output voltage of potentiometers coupled to the container handling mechanism to thereby coordinate actuation of the container handling mechanism and smoothly pick up the container from the curbside, dump the container in the charging hopper, and return the container to the same position on the curbside but above the ground a predetermined distance.

15. The method of automatically engaging lifting, dumping and returning a container of interest comprising the steps of:
-
(a) providing a lift and dump mechanism having sensors and memory adapted to provide and store data indicative of the position of a container being handled by the lift and dump mechanism and a control system adapted to use stored data to return said lift and dump mechanism to a predetermined position; (b) operating said lift and dump mechanism to approach and engage a container of interest to be dumped; (c) sensing and storing data indicative of the position of the lift and dump mechanism at the time of engagement of said container of interest; (d) storing said positional information in memory; (e) lifting and dumping said container; and (f) returning said container to a predetermined position related to the position indicated by the stored positional information wherein said container is returned and released at a position just above that from which it was originally retrieved so that it is not forced into its original support.
