PURPOSE:To prevent falling of board in a hardening system by an arrangement wherein a CPU controls a conveyor width modifying means based on board width data and clearance data stored in a RAM thus modifying the conveyor width. CONSTITUTION:An interface 30 is connected with a far infrared heater 11, a ultraviolet lamp 14, a temperature sensor 22, a tower light 24, a touch panel switch 31, a CRT 32, a buzzer 33, and the like. These are controlled by means of a CPU 34 based on NC data stored in a RAM 35 according to a program relevant to hardening operation stored in a ROM 36. When the conveyor width is regulated for each board 8 based on board width data stored in the RAM 35, a system offset screen is displayed upon touching an offset data operating switch part. Clearance data is then set on the screen thus displayed and a drive motor 45 is driven and then a movable side conveyor 51 is moved in the direction approaching a fixed side conveyor 50 thus preventing the board 8 from falling. |
