ABSTRACT:
A drive belt take-up system for a live roller conveyor. Live roller conveyors are made up of one or more curved and/or rectilinear segments. Each segment comprises a pair of spaced side frames which support the live rollers. The live rollers carry and transport the articles being conveyed. The live rollers are driven by frictional contact with the upper flight of a continuous drive belt. At one end of the conveyor segment one of the side frames (the one with a smaller radius of curvature in the case of a curved segment) supports a powered sheave which drives the belt. The same side frame supports a plurality of idler wheels therealong and a first idler sheave at its other end, all of which maintain the upper flight of the drive belt in frictional contact with the live rollers. From the first idler sheave the drive belt passes about an adjustable take-up sheave. Thereafter the belt passes about a second idler sheave located near the first idler sheave. The belt then passes about at least one return flight idler wheel (if needed) to a third idler sheave. The third idler sheave is located near the power sheave. From the third idler sheave the belt passes about a second adjustable take-up sheave and returns to the powered sheave. It would be within the scope of the invention to eliminate one of the second and third idler sheaves and the corresponding one of the first and second take-up sheaves.
