Abstract

PURPOSE: To stop the operation of the reel accurately at a given winding diameter through the detection of deceleration by determining the winding diameter from the number of pulses generated by the reel before the pulses generated by a movement detection roll reaches a certain number.
CONSTITUTION: A movement detection roll 2 is provided with a proximity switch 5 and a rewinding reel 1 with a pulse generator 5. The number of pulses from the pulse generator is counted with a stop command arithmetic device 7 before the pulses from the proximity switch 5 reaches a certain number. Based on the results, the winding diameter is computed to detect the deceleration point whereby the operation of the reel 1 is stopped. In this manner, as no pinch roll is used for the movement detection roll, the slippage of the material can be eliminated while as the interval of the pulses from the pulse generator 4 corresponds to a given distance, less number of pulses per rotation would cause no arithmetic erros. Accordingly, it is possible to halt the operation of the reel at a given winding diameter.
