Abstract

A pair of conveyor pan immobilizing subassemblies are disclosed for engaging the opposite sides of a conveyor pan to stabilize the pan in a first direction transverse to the conveyed direction of the pan. In one embodiment, each subassembly is comprised of a plurality of pan engagement assemblies, each pivotally mounted for depression in a vertical axis by an off-centered pan, and each spaced further from the conveyor pan in the first direction, such that the pan is serially engaged by the assemblies as a result of pan movement resulting from, for example, loading or unloading of the pan. In another embodiment, the subassembly comprises a roller rotatably mounted for rotation by a pan being moved in the conveyed direction and resiliently mounted for depression by an off-centered pan. The roller is further mounted such that the surface thereof, when in engagement with the conveyor pan, forms an acute angle with a vertical axis, thereby resulting in a wedging engagement of the conveyor pan by both of the subassemblies' rollers.

Claims7

Dependent claims

A conveyor pan immobilizing assembly for immobilizing a conveyor pan having two opposite sides in a direction substantially perpendicular to the conveyed direction of the conveyor pan yet permitting movement of the conveyor pan in the conveyed direction, said assembly comprising

first and second subassemblies mounted for respective engagement with the sides of the conveyor pan that are substantially parallel to the conveyed direction, each subassembly comprising:
a roller for engaging the pan side;
means for rotatably mounting said roller;
and
means for resiliently mounting said roller for movement in the substantially vertical direction, said roller being mounted such that the surface thereof when in engagement with the respective pan side forms an acute included angle with the vertical axis, said resilient mounting means comprising a housing;
an elongate bracket, one end of said bracket rotatably mounting said roller and the other end of said bracket being pivotally mounted in said housing about a first pivot for a predetermined amount of rotation in a first direction and about a second pivot after continued rotation in said first direction beyond said predetermined amount of rotation;
and spring means for resiliently urging said one end of said bracket in an upward direction.
