Abstract
A conveyor includes an assembly for bridging the gap at the end of a conveyor section. It includes an idler roller at the end of the conveyor section. The idler roller is seated in upwardly open slots and can lift completely out of the conveyor frame if an article becomes entrapped between the idler roller and the conveyor belt, in order to release the article.
Claims4
A conveyor, comprising:
- an elongated conveyor frame having an end;
- a belt mounted on said frame, said belt being operable to convey articles in a first direction;
- a pair of upwardly open slots defined by said frame between said belt and said end of the frame;
- and
- an idler roller having first and second ends, each of said ends being seated in one of said upwardly open slots;
- wherein each of said slots is defined by a leading surface, a bottom surface, and a trailing surface, wherein said trailing surface is sloped upwardly and in said first direction of travel so that, if an article were to get caught between said belt and said idler roller, the article would push said idler roller against said trailing surface, and said idler roller would travel up said trailing surface in the direction of travel of the belt and would lift completely out of the frame, thereby freeing whatever was caught.
