PURPOSE:To laminate the iron boards well while allowing the deviation of thickness, by rolling an inclined arm selectively to the left or right upon detection of passage of iron board and ejecting the air selectively through upper and lower air nozzles thereby inverting the iron boards alternatively. CONSTITUTION:A board 11 punched from an iron sheet is carried from a carrying conveyor 19 onto a carrying belt 8. Upon detection of passage of punched board 11 by means of a detector 12, an actuator 14 is functioned to advance a knuckel 13. Consequently, a valve system 16 is functioned to eject compressed air through an air nozzle 17 thus to float the punched board 11 at the moment dropping from a magnet pulley 3 and to drop onto the carrying conveyor 20 without inverting. While upon detection of passage of punched board 11, by means of the detector 12, the knuckle 13 is retreated to roll an arm 5 to the left around the shaft 4 and to eject compressed air through an air nozzle 18 thus to invert the punched board 11 and drop onto the conveyor 20. |
