Claims

[Scope of utility model registration request]

In the pick-and-place process in which a watch gear is picked from a parts feeder and assembled onto a base plate on a pallet, at least two gears are placed on the trajectory of the tip of the navel of the gear picked in the pick-and-place process from the parts feeder to the base plate. The above-mentioned reflective fiber sensors are arranged as a first reflective fiber sensor on the trajectory, and the second and subsequent reflective fiber sensors are arranged at positions shifted by a minute length in the perpendicular direction with respect to the trajectory, When the gear picked by the pick and place moves from the picking position to the assembly position, if only the first reflective fiber sensor detects the navel, it recognizes the gear as a good item and moves it to the base plate. A pick-and-place device that performs an assembly operation and, if a reflective fiber sensor other than the first reflective fiber sensor detects the navel, recognizes the gear as a defective product and stops the assembly operation.
