Sortation conveyor
First Claim
1. A sortation conveyor for selectively diverting articles carried by said sortation conveyor traveling in a downstream longitudinal direction laterally at a divert location, said sortation conveyor having a lateral direction transverse to said longitudinal direction, said sortation conveyor comprising:
- a. an endless conveying surface configured for movement in said downstream longitudinal direction;
b. a switch associated with said divert location;
c. a divert guide path disposed downstream of said switch, said divert guide path comprising a plurality of divert angles;
d. a plurality of pushers carried by said endless conveying surface and configured to travel therewith, each of said plurality of pushers configured to be selectively diverted by said switch to travel along said divert guide path so as to engage and divert a selected one of said articles; and
e. at least a portion of said divert guide path configured to laterally accelerate at least one pusher of a diverted set of one or more of said pushers traveling along said portion when said at least one pusher of said diverted set first contacts said selected one of said articles.

Abstract
A sortation conveyor has a divert guide path which is configured to guide pushers to engage articles disposed on an endless conveying surface at an initial impact which does not result in an out of control situation even at high speeds. The divert guide path is disposed at a plurality of divert angles, and guides pushers to engage articles at a low initial contact divert angle and first lateral speed and to accelerate the articles to a final divert angle and second, higher, lateral speed. The pushers may be undergoing lateral acceleration at the time initial contact is made with the articles.

7. A method of selectively diverting articles disposed on an endless conveying surface moving in downstream longitudinal direction at a divert location, comprising the steps of:
-
a. providing a plurality of pushers mounted on said endless conveying surface; and b. initially contacting a selected one of said articles with at least one pusher of a diverted set of one of more pushers while said at least one pusher is being laterally accelerated. - View Dependent Claims (8)
