PURPOSE:To make the center of a construction board match to the center of a construction board transferring equipment and stop it at the position by measuring the length of the construction board automatically from the movement of a rear end detector and the action of a timer on the basis of a front end detector. CONSTITUTION:A cut rectangular construction board 2 is transferred on a carring conveyor 1, and when the rectangular construction board 2 passes through a rectangular front end detector 3b, the detector 3b detects the front end 2a of the construction board 2. A conveyor 12 for detector moves to the opposite direction to the carrying direction at the same speed as the carrying conveyor. When the rear end detector 4 detects the rear end of the rectangular construction board 2, a timer 6 starts to stop the carrying conveyor 1 after a prescribed time and make the center of the construction board 2 match to the center of the construction board transfer and load apparatus 5. The conveyor 12 for detector is reversed by switching its clatch and stops when the rear end detector 4 is returned to the original position. |
