In the conveyance program 34, these values are undetermined as variables (Xb, Yb, Tb1 to Tbn), etc., and the holding position information generating unit 38 determines each of the above undetermined values from the machining position information F1 of the machining program 32. The position value is calculated and generated (S7). At this time, the holding position information generating unit 38 generates information on each undetermined position so that the suction pad 17 is not positioned at the processing position of the plate material W and the whole plate material W can be sucked in a well-balanced manner according to the setting rule. To do.
The transport control device 33 uses the value generated in this way, for example, by substituting it into the above variables, and executes the transport program 34 to hold the whole plate W again, that is, to re-adsorb (S8). The plate material transport device 4 that holds the whole in a well-balanced state carries the plate material W to the target unloading position (S9).

  In this way, the plate material production control apparatus 1 sets the stop position value at the time of re-holding of the conveyance program 34, etc. to be undecided, and immediately before unloading the plate material W from the plate material processing machine 3, the processing position from the processing program 32 is determined. Since the information F1 is received and the undetermined value is calculated by the holding position information generating means 38, the appropriate position of the plate material W is held by the suction pad 17 for the plate materials W having different processed shapes, and stable.
