Abstract
Off-loading conveyors having endless roller chains to which are mounted bow tie rollers on rods extending laterally from the chain. The bow tie rollers define concavities for receipt of product units to be conveyed and off-loaded at an appropriate station. Off-loading elements are mounted to the chains which include paddles extending to between the bow tie rollers. The off-loading elements include levers which cooperate with an actuation system to pivot the paddles through the concavities to remove product at appropriate stations.
Claims26
An off-loading conveyor comprising a support structure defining a conveying path;
- an endless chain mounted on said support structure to extend along said conveying path;
- support elements mounted to said chain, said support elements being mutually spaced apart and including support surfaces defining concavities between adjacent said support elements;
- off-loading elements mounted on said chain and including paddles fitting through said concavities between adjacent said support elements, each said paddle being pivotable about an axis substantially parallel to the path of travel of said chain and having a retracted position inclined downwardly toward the free end of said paddle and facing a said concavity, each said off-loading element being aligned for passage of said paddle from said retracted position through said concavity with said paddle remaining inclined downwardly toward the free end thereof to off-load away from the pivot axis of said paddle.

An off-loading conveyor comprising
- a support structure;
- an endless roller chain mounted on said support structure and having links and roller, said links being coupled end-to-end by said rollers;
- rods fixed to said links and extending in a first direction laterally of said chain;
- support members mounted on said rods laterally of said chain, spaced one form another and having support surfaces, concavities being defined by said support surfaces of adjacent said support members;
- off-loading elements mounted on said chain and including paddles fitting through said concavities between adjacent said support elements, each said paddle being pivotable about an axis substantially parallel to the path of travel of said chain and having a retracted position inclined downwardly toward said first direction and facing a said concavity, each off-loading element being aligned for passage of said paddle from said retracted position through said concavity with said paddle remaining inclined downwardly toward said first direction to off-load away from the pivot axis of said paddle.

- support elements mounted to said chain, said support elements being mutually spaced apart and including support surfaces defining concavities between adjacent said support elements;
- off-loading elements mounted on said chain and including paddles fitting though said concavities between adjacent said support elements and levers extending away from said paddles, each said paddle having a retracted position facing a said concavity and inclined downwardly toward said concavity and being pivotable about an axis substantially parallel to the path of travel of said chain, said off-loading elements each being aligned for passage of said paddles from said retracted positions through said concavities with said paddles remaining inclined downwardly to off-load away from the pivot axis of said paddle;
- an actuator engageable with said levers to pivot selectively said off-loading elements for passage from said retracted positions through said concavities.
