WORKPIECE CONTROL DEVICE

PURPOSE:To provide a workpiece control device capable of performing the automatic stock control and the like of workpieces. CONSTITUTION:Inside a slidable drawer 5, a case 2 can be stored into each storage part 27. When the case 2 is stored, a plate spring 42 is protruded outward. A timing plate 41 is provided in the outward protruding state at each storage part 27. A first to a thrid sensors 51-53 are provided at the side part, corresponding to the tip part of the drawer 5, of a front face plate 20. At the time of pulling out the drawer 5, the pull-out quantity and pull-out direction can be known by the action of the timing plates 41 and the first and second sensors 51, 52. After the putting-in/out of the case 2, the drawer 5 is pushed back. In the storage parts 27 having the cases 2 therein, the plate springs 42 are detected by the third sensor 53 so as to know the number of stored cases 2. The number of delivery or storage can be known by comparing the original number of stock with the count at the push-back time.
