Chain tension sensor

摘要

A chain tension sensor for a chain conveyor, the conveyor including a frame and a chain having a plurality of flights. The tension sensor includes a reaction arm and a load sensing pin. The reaction arm includes a first end, a second end opposite the first end, and a load pad. The first end is pivotably coupled to the frame by a pivot pin defining a pivot axis. The load pad is adjacent the conveyor chain and positioned to contact flights passing the load pad. The flights contacting the load pad exert a force on the reaction in a direction that is perpendicular to the pivot axis. The load sensing pin is coupled to the reaction arm such that the load sensing pin senses the force that is exerted by the flights.

1. A tension sensor for a chain conveyor, the chain conveyor including a frame and a chain having a plurality of flights, the tension sensor comprising:
a reaction arm configured to be coupled to the frame, the reaction arm including a first end, a second end opposite the first end, and a load pad, the reaction arm being pivotable about the first end, the load pad positioned adjacent the conveyor chain and configured to contact the flights as they move past the load pad, the flights contacting the load pad exerting a force on the reaction arm; and a load sensing pin coupled to the reaction arm and operable to sense the force exerted by the flights.
