Abstract
An endless conveyor belt for the conveying of separate articles or packages to be conveyed along a steep incline. The belt is formed with spaced, resilient flaps which extend upwardly from the load supporting surface to engage the conveyed article. If the article slides backwardly on the belt, the flap bends and pivots upwardly so that a roughened surface will tend to retard the sliding movement. After the article is removed, the flap is restored to a position within a recess in the belt surface during the return run.
Claims11
An endless conveyor belt of cords embedded in rubber or plastic for conveying articles up a steep incline, said belt comprising:
- a substantially continuous smooth surface on one side adapted for engagement with guide rolls;
- a load supporting surface on the other side having a plurality of recesses at spaced locations along the length thereof;
- a plurality of article engaging flaps each resiliently attached at its trailing edge to the trailing end of one of said recesses and having an underside and being shaped to fit into said recess to pass over support rolls engaging the load supporting surface;
- each said flap having a volume substantially filling the volume of its corresponding recess when disposed therein and being resiliently biased outwardly at a small acute angle with the load supporting surface of the belt whereby its leading edge normally extends above the load supporting belt surface at a loading zone for engagement with articles to be conveyed;
- said flaps being made of a strip of rubber or plastic material and formed to bend due to loading with the leading edge moving rearwardly in a generally arcuate path to cause the underside of said flap to engage a large article being conveyed.
A conveyor system for conveying large articles along a path having a steep inclination including:
- a conveyor belt having a load carrying surface on one side and a substantially continuous surface on the opposite side adapted to engage the guide rollers;
- a plurality of guide rollers including an upper roller, a lower roller, and intermediate rollers in contact with said continuous belt surface for defining an endless path for said conveyor belt, said path including a load carrying path portion and a return path portion with at least one belt engaging roller located in return path portion to be in contact with the load carrying surface on said belt;
- said load carrying surface having a plurality of recesses at spaced locations along the length thereof;
- a plurality of article engaging flaps each resiliently attached at its trailing edge to the trailing end of one of said recesses and having an underside and being shaped to fit into said recess to allow a return run of said belt to pass over said belt engaging roller;
- said flap having a volume substantially filling the volume of its corresponding recess when disposed therein and being resiliently biased upwardly at a small acute angle relative to the load carrying surface of said conveyor belt so that a leading edge of the flap will extend above the load carrying belt surface at a loading zone for engagement with articles to be conveyed;
- said flaps being made of a strip of rubber or plastic material and formed to bend due to loading with the leading edge moving rearwardly in a generally arcuate path to cause the underside of said flap to engage an oversized article being conveyed;
- and
- means on the underside of said flap being formed to resist relative sliding movement with said article.
