A position controlling device which makes use of air pressure for finishing column of fabrics

摘要

The present invention relates to an end position control device for fabric using air pressure, comprising: an air sensor for detecting an end of a fabric in motion according to a flow of compressed air supplied from a compressor operated by a switch box operated by an operator;;A servovalve for controlling a path of compressed air moving inside according to a state in which the diaphragm moves up and down by the pressure of air flowing through the air sensor;;A bolt rod that receives the rotational force of the pneumatic motor that generates forward and reverse rotational force through the reduction gear according to the state in which the compressed air is supplied through the servovalve and always controls the fabric to the correct position;;A constant pressure regulator for supplying the compressed air supplied from the compressor to the valve body and the pneumatic motor through a dehumidifier while maintaining a constant pressure;;Compressed air passing through the static pressure regulator is controlled by the speed valves to be supplied to the air sensor to detect the end of the fabric by the pressure according to the amount of air when the fabric is wound or unwound, the fabric is one side or other By rotating the bolt rod to the forward and reverse while controlling the rotation direction of the pneumatic motor by the biased state to the side so that the fabric can always be controlled to the right position.
