Dynamic discharge compensation for a sortation system
First Claim
Patent Images
1. A method of discharging an article from a sortation system, the article positioned off-center on a selected moving carrier of the sortation system, the method comprising:
- detecting a longitudinal component of a relative location of the article positioned off-center on the selected moving carrier;
determining a release point for discharging to a selected stationary discharge location, the release point compensating for at least the longitudinal component of the relative location of the article positioned off-center; and
determining whether the release point has been reached; and
in response to determining that the release point has been reached, initiating discharge of the article positioned off-center by the selected moving carrier.

Abstract
The discharge accuracy of unit sortation is improved by making real time adjustments to the discharge timing of the carrier based on the determined actual position of each article on respective carriers. The adjustments are applied at the time the discharge command is given.

8. A material handling system, comprising:
-
an endless conveyor having more than one moving carrier that moves past more than one stationary discharge location; an image device positioned to detect an article positioned off-center on a selected moving carrier; a controller in communication with the endless conveyor and image device to perform operations to; detect a longitudinal component of a relative location of the article positioned off-center on a selected moving carrier of the endless conveyor; determine a release point for discharging to a selected stationary discharge location, the release point compensating for at least the longitudinal component of the relative location of the article positioned off-center; and determine whether the release point has been reached; and in response to determining that the release point has been reached, initiate discharge of the article positioned off-center by the selected moving carrier. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A controller, comprising:
-
an interface to an endless conveyor; at least one processor; and a memory, wherein the at least one processor is coupled to the memory and the interface and configured with processor-executable instructions to perform operations to; detect a longitudinal component of a relative location of an article positioned off-center on a selected moving carrier of the endless conveyor; determine a release point for discharging to a selected stationary discharge location, the release point compensating for at least the longitudinal component of the relative location of the article positioned off-center; and determine whether the release point has been reached; and
in response to determining that the release point has been reached, initiate discharge of the article positioned off-center by the selected moving carrier. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
