JPS6453990A - Automatic wire winder - Google Patents

Abstract

PURPOSE:To get rid of the entanglement of an element wire out of a full bobbin automatically by rolling a wire terminal with a mill roll at the time of bobbin fullness, and forming it into a curl of curvature smaller than a winding outer diameter with a reform roll. CONSTITUTION:At the time of winding an element wire (a) onto a bobbin 1, a mill roll 11 and a reform roll 14 come to open and it is wound up. When it comes to a full wind, a winder 7 is once stopped, pressure oil is fed to a cylinder 17 of the mill roll 11, and rolling of the element wire (a) is started, while the reform roll 14 is also closed. And, the winder 7 is restarted, and the element wire (a) is curled at curvature smaller than the outer circumference of a full bobbin by a reform roll 14 as being rolled and hardened. Then, the element wire (a) is cut by a cutter 13, and a terminal of the element wire (a) rolled on the bobbin is pressed to a winding layer. Consequently, it is unnecessary to do any locking by man power, thus automation can be done and, what is more, labor-saving can be done as well.
