Abstract:
An automatic door panel producing apparatus, said apparatus comprising:a first uncoiler being wound around an inner plate material and for supplying the wound inner plate material; a first leveler for regulating a flatness of the inner plate material supplied from the first uncoiler; a presser for forming a pattern on the inner plate material fed from the first leveler; a marking device for marking a cutting position on the inner plate material from the presser; a bend controller for controlling a bend of the inner plate material from the marking device, wherein the bend controller includes a sensing device for sensing a bend of the inner plate material from the marking device, a support member for supporting the inner plate material from the sensor, and a guide member for guiding the inner plate material supported by the support member; wherein the support member includes a supporting body mounted on guiding rollers contacting a bottom surface of the bent inner plate material from the sensing device for supporting the bent inner plate material and a height controller mounted on a bottom surface of the supporting body; and wherein a height of the height controller is adjusted according to a weight of the bent inner plate material supported by the supporting body to control an up-and-down motion of the bent inner plate material; a second uncoiler being wound around an outer plate material forming an outer surface of the door panel for supplying the wound outer plate material; a second leveler for regulating a flatness of the outer plate material supplied from the second uncoiler; a roll forming device for roll-forming both edges of the inner and outer plate materials from the bend controller and second leveler; a heater for preheating the inner and the outer plate materials from the roll forming device; an injector for injecting insulated material between the inner and outer plate materials preheated by the heater; a marking sensor for sensing the mark on the inner plate material from the injector and outputting a sensing signal; and a cutter for cutting the door panel at a fixed size according to the sensing signal from the marking sensor.
