Abstract
An input station for a belt conveyor of the kind including a continuous conveyor belt that moves in a conveyor run through an input station to a discharge location, around a head pulley, and in a return run around a tail pulley back to the input station and the conveyor run. At the input station the conventional center support rollers are retained but the support rollers along the sides of the belt are replaced by a plurality of elongated, stationary, flat support members that support the sides of the conveyor belt throughout the input station, improving the seal to input station skirtboards and materially reducing or eliminating input leakage while maintaining roller support and flexibility in the center of the belt, with minimal friction increase.
Claims6
A side roller replacement kit for the input station of a belt conveyor of the kind comprising a continuous conveyor belt of given width having a conveyor run extending through an input station to and around a head pulley at a discharge location, and a return run from the head pulley to and around a tail pulley back into the input station, the input station comprising a frame, including a plurality of N pairs of center stanchions each aligned with two side stanchions, located beneath the conveyor run of the belt at an input location, center belt support means comprising a plurality of N center support rollers each having a length less than the belt width, each center support roller mounted between one pair of center stanchions, so that the center support rollers support the central portion of the conveyor belt throughout the input station, and first and second lateral belt support means, on opposite sides of the frame adjacent the center belt support means, each lateral belt support means comprising a plurality of N side support rollers each having a length less than the belt width, each side belt support roller mounted between one center stanchion and one side stanchion;
- the side roller replacement kit comprising:
- two sets of lateral support members, N lateral support members in each set, each lateral support member mountable between a center stanchion and a side stanchion, in place of one of the side support rollers;
- two sets of belt support rails;
- and two sets of mounting means, one for each set of belt support rails, for mounting the belt support rails on the lateral support members with the belt support rails extending longitudinally of the belt and with each set of belt support rails supporting one side of the conveyor belt at an acute angle to the central portion of that belt throughout the input station.
