PURPOSE:To avoid the waste of time needed for replacement of tools as well as the discontinuation of a production line, by storing previously the types and numbers of tools used for a producing device and calling and setting a tool corresponding to the type of a specific processing machine according to the information on said stored types and numbers of tools. CONSTITUTION:Switches 90, 94 and 132 are turned on to store the types and numbers of producing devices in registers 92 and 96. The type of a tool 14 is read by sensors 106a-106d. The information on the type of the tool 14 is compared with the signal sent from a comparator 98 via a code conversion part 108 to decide the propriety of the type of the producing device and the tool 14. When the affirmative decision is obtained, a production working sequence circuit 110 is energized. Then the tool 14 is shifted to its set position and a work is fixed. Thus the production is started. A counter 102 counts the products processed and sends signal to a tool exchange working sequence circuit 104 when the processing is through. While the next tool 14 is selected via a sensor 120, a code conversion part 122, a tool number memory circuit 126 and a comparator 100. The selected tool 14 is set via sequence circuits 116 and 118 according to the signal sent from the circuit 104. |
