ABSTRACT:
A modular checkweigher/grader system is disclosed. A feed conveyor is provided for directing items to be weighed to a weighing conveyor. The entire system is modularly designed using lightweight durable materials, such as plastics and stainless steel. Each conveyor includes a conveyor belt in contact with upper and lower surfaces of a platform. The belts are tightened and loosened with quick release tension clamps and driven by air powered motors. The feed conveyor is attached to a frame by toggle clamps. The weighing conveyor is attached to a load cell which is connected to the frame by toggle clamps. These toggle clamps permit the entire feed and weighing conveyors to be easily removed. All of the air and electrical connector to the conveyors are by quick release connectors. The entire weighing conveyor is used as the weighing platform. A tachometer may be used to regulate the conveyor speed. A modular grading conveyor is disclosed for categorizing objects from the weighing conveyor. A tensioner is provided for allowing the grader belt to be slackened for easy cleaning. Grader paddle control modules are hinged for easy cleaning. The hinges are secured by butterfly nuts for easy removal of broken modules. All air and electrical connections to the paddle control modules are by quick release connectors.
