Abstract
PURPOSE: To protect the winder and coil from being damaged by making the cradle contact slightly with the coil in a mechanism wherein the cylinder to lift the winding coil cradle is actuated by hydraulic pressure being controlled and reduced thru relief valve.
CONSTITUTION: Winding operation at the coil 13 is carried out along the sequence as below: (a) by the operation of valve 18, wedge piece 9 is moved to the left via cylinder 11, which enlarges the diameter of the drum 8 being consisted of a plurality of a plurality of segments, (b) at the same time, by the operation of the valve 37, pressure at the reducing valve 30 is made equal with the value set at the relief valve 3l via the bypass pipe 33, then, (c) the winding of the coil 13 is started. Before the winding is finished, by the operation of the valve 28, hydraulic pressure being reduced at the reduction valve 30 is supplied to the down chamber C of the cylinder 21 which lifts the cradle 20 upward and after making it contact with the coil 13 slightly, supply of hydraulic pressure is suspended by operating the valve 28. After the winding is completed, diameter of the drum 8 is shrunk thru the cylinder 11 by operating the valve 18, valve 37 is switched, setting the pressure at the chamber C of the cylinder 21 at the value as set at the relief valve 32, and the coil is drawn out while the coil is being supported by the cradle.
