Abstract
Apparatus and method for activating conveyor belt roller assemblies by lowering and extending wearstrips to selectively lower the conveyor belt to place the conveyor belt roller assemblies into contact with actuating rollers. A wearstrip module housing the wearstrips includes an upper support upon which the wearstrips are mounted that is longitudinally and vertically movable relative to a lower support fixed relative to the actuating rollers. Mounting brackets rotatably mount the lower support and actuating rollers in a fixed position and orientation.
Claims16
A wearstrip module for selectively raising and retracting a set of wearstrips for a conveyor, comprising:
- a lower frame comprising a pair of lower side walls connected to each other, the lower side walls including ramps at upper edges;
- an upper frame comprising a pair of upper side walls connected by a bottom wall for mounting the wearstrips, the upper side walls including downwardly angled edges that protrude below the bottom wall, the downwardly angled edges complementary to the ramps;
- an actuator attached to the upper frame and the lower frame, wherein the actuator selectively moves the upper frame longitudinally to effect vertical movement of the upper frame relative to the lower frame.
