Patent number: 7540374Abstract: A conveyor system and method of measuring chain wear includes first and second sensing devices positioned at a conveyor line or path and directed toward a conveyor chain that is movable along the conveyor path. The first sensing device senses the presence of a first chain portion of the conveyor chain at a predetermined location as the conveyor chain moves along the conveyor line. The second sensing device senses a second chain portion of the conveyor chain as the conveyor chain moves along the conveyor line. The second sensing device is operable to sense a location of or distance to the second chain portion or may capture an image of the second portion. A controller is operable to determine a degree of wear of a section of chain extending between the first and second chain portions in response to the second sensing device.Type: GrantFiled: August 17, 2007Date of Patent: June 2, 2009Assignee: Frost Links, Inc.Inventors: Jonathan M.

Patent number: 7325669Abstract: A conveyor system includes a conveyor line, a conveyor chain movable along the conveyor line, and an electronic device located at a movable component that moves with the chain along the conveyor line. The electronic device may comprise a locating device operable to generate a locating output indicative of a location of the movable component along the conveyor line. Optionally, the electronic device may comprise a sensing device operable to sense a chain characteristic at the component and to generate a sensor output indicative of the chain characteristic. Data collected by the electronic device may be stored at the device and/or transmitted to a controller of the conveyor line. The controller may be operable to determine the chain characteristic at a particular location of the transmitting device in response to the device output.Type: GrantFiled: November 21, 2006Date of Patent: February 5, 2008Assignee: Frost Links, Inc.Inventors: Charles C Frost, Jonathan M Rathbun
