Abstract
Abstract A sorting conveyor having a plurality of movable plaques on one conveyor base arranged to sort merchandise or similar articles carried on another conveyor positioned at one side of the sorting conveyor. The separation of articles may be controlled by some particular property of the articles such as weight, size, or color, sensed in a known manner. The plaques on the sorting conveyor are activated to engage the articles carried by the adjoining conveyor and change their relative position so that a series of fences can direct the reoriented articles into predetermined paths.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A side transfEr or side push sorting-conveyor for directing articles into a plurality of paths while they are being carried by a conveyor comprising: a. A conveyor for moving the articles to be sorted, b. means for spacing the articles a predetermined distance from each other; c. a sorting conveyor parallel to and in side-by-side relationship with the article conveyor; d. a plurality of transverse rods on said sorting conveyor, e. Power means coupled to the transverse rods to drive the said rods in a plane parallel to the plane of the article conveyor. f. A plurality of plaques slidably mounted on said rods and including a cam follower on each bar for positioning the bars along the rods; g. a linear cam for engaging the cam followers and for laterally moving the plaques into contact with articles on the belt conveyor whereby certain of the articles are slid to a sorted position, h. a rockable gate at the entrance end of the cam; i. and a sensing means for determining the class of an article, said sensing means coupled to said gate for operating it to either engage or disengage said cam followers.
