Abstract
A conveyor apparatus has at least one power-driven roller arrangement for a positive engagement and feed of an item in the conveying direction, and an incremental feed device situated downstream of the roller arrangement as viewed in the conveying direction. The incremental feed device includes an incremental feed roller spaced from the roller arrangement; an energy storing device connected to the incremental feed roller; and a mechanism for urging the item against the incremental feed roller for rotating the incremental feed roller by the item advanced by the roller arrangement to arm the energy storing device and for further advancing the item by the incremental feed roller during energy release by the energy storing device.
Claims5
In a conveyor apparatus having at least one power-driven roller arrangement for a positive engagement and feed of an item in the conveying direction, the improvement comprising an incremental feed device situated downstream of said roller arrangement as viewed in the conveying direction, said incremental feed device including
- a. an incremental feed roller spaced from said roller arrangement, each item being advanced into the zone of said incremental feed roller by said roller arrangement;
- b. means for urging the item into frictional contact with the periphery of said incremental feed roller for rotating said incremental feed roller from a first position to a second position by said roller arrangement with the intermediary of the item being advanced;
- and
- c. an energy storing means connected to said incremental feed roller for being armed by said incremental feed roller during its rotation from said first position to said second position and for rotating said incremental feed roller from said second position towards said first position codirectionally with the rotation from the first position to the second position to further advance the item in said conveying direction.
