PURPOSE:To make a conveyor stoppable accurately irrespective of material weight, by positioning a position detector to the setting stop position by a comparative conformity detecting circuit in advance, while detecting the stop position arrival with a detecting signal out of the position detector, and outputting a stop command. CONSTITUTION:A stop position adjusting device 6 is set to the specified stop position in advance by a driving control circuit 12, comparing the setting stop position 10 in a comparative conformity detecting circuit 11 and the output of a position detector 9. Under this condition, a material 2 arrives at the stop position and comes into contact with a movable part 8 which is therefore displaced to the right. This displacement is detected with the position detector 9, and when arrival to the specified position is detected, a conveyor 1 is stopped via a conveyance controller 15. With this constitution, accuracy in the stop position is improved. |
