PURPOSE:To aim at enhancing and automatizing the production of various kinds of products, by referring the list of articles in one rot unit, and by controlling a status instruction for operating a sorting and accumulating device in accordance with the kind of each process, in accordance with a row of products which are successively processed. CONSTITUTION:When an NC turret punch press 1 completes the process of a part, an unloader 3 is operated in accordance with NC data, and thus processed part is transferred to an accumulating device 5R or 5L. An instruction for pulling out an empty pallet is delivered to the accumulating device 5R or 5L, simultaneously with the start of the process. The empty pallet Pj is set on the accumulating device 5L, and the processed part is set on the pallet. Then, a pallet exchange flag for the part is referred to, and therefore, the pallet is returned to its original multi-stage stocker position or is left to be set on the accumulating device. Accordingly, in association with the operation of the NC press 1, the unloader 3, the accumulating devices 5R, 5L, multi-stage stocker 7R, 7L and a stacker crane 11 are operated in synchronization with each other to realize automation. |
