Device for transferring platforms movable on rollers from a conveyor to a cross-conveyor
First Claim
1. A transfer station operable on a platform conveyor system for transferring a platform (5), displaceable on rollers (3), from a first conveyor (1) to a second, intersecting conveyor (2) in which said platform conveyor system moves the platform (5) along said conveyors (1, 2) by a plurality of driven, vertically rotatable friction wheels positioned alongside said conveyors (1, 2), said rollers (3) being rotatably mounted in said conveyors (1, 2) and spaced along said conveyors (1, 2) so as to contact said platform (5) when said platform (5) is adjacent each of said rollers (3), comprising:
- a rotatable friction wheel assembly (24) positioned in an intersection point where said first conveyor (1) intersects said second conveyor (2) comprising;
a frame;
a swing lever (12) mounted to said frame so that said swing lever (12) is rotatable about a vertical swing axis (13), said swing axis (13) positioned adjacent to said conveyors (1,
2); and
at least one friction wheel (11) rotatably mounted to said swing lever (12) so that said friction wheel (11) is capable of making contact with said platform (5) to drive said platform (5) along either of said conveyors (1,
2).

Abstract
A device for transferring platforms movable on rollers from one conveyor onto another cross-over conveyor, the platforms being driven along the conveyors by motor driven friction wheels positioned along the conveyor so as to contact the outer surfaces of the platform. A pair of friction wheels are mounted on a rotatable swing lever of a rotatable friction wheel assembly so that the frictional wheels engage and drive the platform from one conveyor to the other.

16. A transfer station operable on a platform conveyor system for transferring a platform, displaceable on rollers, from a first conveyor to a second, intersecting conveyor in which said platform conveyor system moves the platform along said conveyors by a plurality of driven, vertically rotatable friction wheels positioned alongside said conveyors, said rollers being rotatably mounted in said conveyors and spaced along said conveyors to as to contact said platform when said platform is adjacent each of said rollers, comprising:
a rotatable friction wheel assembly positioned in an intersection point where said first conveyor intersects said second conveyor comprising; a frame; a swing lever mounted to said frame so that said swing lever is rotatable about a vertical swing axis, said swing axis positioned adjacent to said conveyors; and two friction wheels rotatably mounted to said swing lever, a first of said friction wheels being mounted at a first end of said swing lever, and a second of said friction wheels being mounted at a second end of said swing lever, so that said first friction wheel is capable of making contact with said platform to drive said platform along said first conveyor, and said second friction wheel is capable of making contact with said platform to drive said platform along said second conveyor. - View Dependent Claims (17, 18, 19)
