HEIGHT POSITION SETTING METHOD OF COIL CAR TO COIL IN WINDING MACHINE

摘要

PURPOSE:To set a height position of a coil car to a coil, by providing a load cell on the upper and lower faces of the outside circumference of a bearing and a mandrel, detecting a stress distortion quantity of its upper and lower faces, and stopping oil pressure supply to a hydraulic cylinder for lifting a coil placing plate, by an operating output in the point of time when its compare-operated values become equal. CONSTITUTION:On the upper face of a coil placing plate 7, a proximity switch 8 for detecting a fact that the lower face of the outside circumference of a coil 4 in a mandrel 1 approaches a necessary distance is provided. The proximity switch 8 applies an approach detecting signal of the coil 4, as an input signal for starting operation of a compare-operator 11 and a signal for operating reduction of an oil pressure flow rate to an oil pressure control device 12. Also, on the upper and lower faces of the outside circumference of a bearing 2 of the mandrel 1, load cells 9, 10 are provided, and its stress distortion quantity is detected and is sent to the compare-operator 11. The compare-operator 11 compares it, outputs it to the oil pressure control device 12 when it becomes almost equal, and stops supply of oil pressure to a lifting oil pressure cylinder 6.
