TRACKING SYSTEM

PROBLEM TO BE SOLVED: To provide a tracking system preventing a work which is being transported by a conveyor from being moved for a period when the work is transported from the reading location of an image to a clamping location. SOLUTION: Carrier plates 12 are continuously fitted in the longitudinal directions of a pair of left and right chains 13, etc. Adhesive sheets 26 made of adhesive urethane rubber, etc., are fitted on the surfaces of the carrier plates 12. Therefore, positional deviation is not generated while the work is transported from the photographing location of an image pickup device 3 to the clamping location by a robot even when the attitude of the work is unstable and is easy to roll because the work is transported in a state that the work is adhered to the adhesive sheets 26. Therefore, the robot is capable of surely clamping the work at the clamping location when the work comes to the clamping location.
