    • PURPOSE:To prevent damage of winding material and deformation of said winding material and nose by arranging a load detector and a liquid pressure cylinder below V-type lifter to sense the variation of load except the winding material to be applied onto the lifter and lifting/lowering the lifter. CONSTITUTION:Roll paper 4 is carried by crane and mounted onto V-type lifter 30 while a limit switch is set and upon contact of the uppermost potion of the roll paper 4 against said switch, lifting of the frame 27 and V-type lifter 30 is stopped. Then the left and right noses 7L, 7R are brought near to the inner diameter end 8b and pressure contacted to produce negative or positive force which is detected through a load cell 29 to execute comparison in control board and to function a short cylinder 28 such that said value will be within the range between Pmax and Pmin. Upon reaching to Pmax, the noses 7L, 7R will advance by X1 such that first advance is performed at the position n1 while pressure contact is released upon second function of short cylinder 28. It is repeated to advance to X2 and stop automatically at the position n2 thus to enable chucking and to prevent deformation of winding material and nose.
    • 目的:通过将负载检测器和液压缸布置在V型升降器以下,以防止施加到升降机上的卷绕材料的负载变化,提升/提升卷绕材料和鼻梁的变形, 降低升降机 规定:卷纸4由起重机承载并安装在V型升降器30上,同时设置限位开关,并且当卷纸4的最上部与所述开关接触时,框架27和V型升降器30的提升 被停止 然后左右鼻子7L,7R靠近内径端8b并接触压力,以产生负或正的力,该负力或正向力通过测力传感器29检测,以在控制板中进行比较,并使短气缸28起作用,使得 所述值将在Pmax和Pmin之间的范围内。 在达到Pmax时,鼻7L,7R将前进X1,使得在短筒28的第二功能时释放压力接触时,在位置n1执行第一提前。重复前进到X2并自动停止在位置 n2,从而能够夹持并防止卷绕材料和鼻子的变形。
