A Research on Automatic Detection Device for the Missing of the Roller Chain's Rollers and Sleeves

The set of automatic detection device for the parts missing of the roller chains rollers and sleeves is based on the displacement transfer theory of the lever mechanism and combined with the integration of PLC control. The levers one end is the detection head close to the roller chain and the other end is the induction head, its support is placed on the base. Sensor puts the induction information into the PLC, and then the PLC make the Synthetic judgment to control the chains drive mechanism to slow down and marking on the places that have missing some parts on time. Its a device has high reliability and high efficiency, which can realize auto-running to replace manual check perfectly.
