Abstract
An off-loading conveyor including a support structure mounting an endless chain to extend along a conveying path. Roller carriages including roller mounts and laterally extending elements are pivotally mounted to the chain on either side thereof. The laterally extending elements and the laterally extending rollers define cavities for receipt of conveyed product units. The roller carriages and associated rollers are positionable in a first, conveying position and a second, off-loading position. The roller carriages rotate downwardly about axes extending laterally of the chain to achieve the second, off-loading position. Control members pivotally mounted to the chain selectively control rotation of the roller carriages from the first to the second positions upon actuation by a solenoid cam mechanism.
Claims61
A conveyor comprising
- a support structure defining a conveying path;
- an endless chain mounted on said support structure to extend along said conveying path;
- roller carriages movably mounted on said chain;
- rollers rotatably mounted to said roller carriages, said rollers extending laterally of said chain and defining cavities for conveying along said conveying path, said roller carriages being movably mounted to move selectively said rollers downwardly away from said conveying path;
- elongate members mounted to said chain and extending laterally of said chain, said elongate members being positioned higher than said rollers when on said conveying path;
- control members mounted on said chain to selectively control movement of said roller carriages.

A conveyor comprising
- a support structure defining a conveying path;
- an endless chain mounted on said support structure to extend along said conveying path;
- members extending laterally from said chain at a first level, said members being mutually spaced along said chain;
- mounts operatively mounted to said chain;
- rollers rotatably mounted to said mounts to extend laterally of said chain, said mounts and said rollers including first, conveying positions and second, off-loading positions, said rollers being located between adjacent said members along said chain and at a second level below said first level when on said conveying path in said first, conveying positions, said rollers in said first, conveying positions and said members defining cavities along said chain, and said rollers being displaced downwardly when in said second, off-loading positions along said chain from said first, conveying positions;
- control members mounted on said chain to control selection of said first, conveying and second, off-loading positions.

A conveyor comprising
- a support structure defining a conveying path;
- an endless chain mounted on said support structure to extend along said conveying path;
- members extending laterally from said chain at a first level, said members being mutually spaced along said chain;
- mounts mounted on said chain selectively pivotable downwardly relative to said chain when on said conveying path about an axis extending laterally of said chain;
- rollers rotatably mounted to said mounts to extend laterally of said chain, said mounts and said rollers including first, conveying positions and second, off-loading positions, said rollers being located between adjacent said members longitudinally along said chain and at a second level below said first level when on said conveying path in said first, conveying positions, said rollers in said first, conveying positions and said members defining cavities along said chain, and said rollers being displaced downwardly when in said second, off-loading positions along said chain from said first, conveying positions;
- control members mounted on said chain to selectively prevent rotation of said roller carriages from said first, conveying positions to said second, off-loading positions.
