JPS6067375A - Checking device for starting end in winding of wire - Google Patents

Abstract

PURPOSE:To minimize the rising height of the starting end section in winding of a wire, by checking the wire in a check hole with the starting end section thereof being made in a bent shape. CONSTITUTION:The starting end section 1' in winding of a wire 1 is bent in a substantially Z-like shape. A bent shaft 9 is pulled out, and a spool 2 is rotated in the same clockwise direction as that of the bent shaft. The leading end of the starting end section 1' in winding comes off from a stationary slit 10 when the spool 2 is started to rotate, and abuts against a retainer spring member so that the stepped section (c) between bent points (a, b) is resiliently pressed against the inner surface of a check hole 5. With the rotation of the spool being continuously sustained, the stepped section (c) rotate about the check hole 5 as a fulcrum while it is pressed against the check hole 5, to retract the retainer spring member 11, and then comes off from the retainer spring 11 so that the leading end abuts against the inner peripheral surface of a winding drum 3. Thereby, the starting end section 1' in winding, being left as it stands, is checked such that it is laid along the inner and outer surfaces of the check hole 5, and then the orderly winding of the wire onto the winding drum 3 is initiated.

Immediately after that, align winding begins, so the wire rod (1) is inserted into the fjt stop hole (5). Although it is easy to insert and is advantageous in terms of man-hours and equipment, it also has the following problems that need to be solved. In other words,
After the winding start end (1°) of the wire rod (1) is applied with the bending force IL, when #@14 (1) is pulled by the rotation of the spool (2), it is locked in the locking hole (5). There is a possibility that the curved part that is to be bent will expand and come out of the locking hole (5), and if it does not come out, the part that is locked in the locking hole (5) will be stuck in the winding drum (3). ) may be slightly raised from the outer circumferential surface of the winding drum (3), which may cause disturbances in the wire winding.Also, the curved wire winding start end (1') is slightly raised from the inner circumference of the winding drum (3). Because the rising height from the surface is large, when carrying the spool (2) with completed wire winding, there was a risk of injury from touching the starting end of the wire winding that rose inside the winding drum (3). .

、これにより」二記目的が達成される。28 Structure of the Invention The present invention provides a bending shaft having a bifurcated tip similar to that described above, and a straight line extending from the bending shaft in the vicinity of a predetermined position in the winding drum of the spool where the tip end of the bending shaft is placed when the winding start end of the wire rod is latched. The structure includes a fixed slit through which the winding start end of the wire rod is inserted, and a holding spring material that elastically presses against the bent winding start end of the wire rod when the bending shaft is withdrawn. Bend the tip of the wire at the beginning of winding from the JJI hole in the spool winding drum,
After inserting the wire into the fixed slit, leave a part of the tip in the fixed slit and rotate the bending shaft by a certain angle (approximately 90 degrees) to bend the tip of the wire at the beginning of winding, and then withdraw the bending shaft. The tip of the wire jr4vi +lI+ is pressed elastically into the latch hole using a pressing spring material, and the spool is rotated in the same direction as the direction opposite to the direction in which the wire is pressed, and this rotation causes the bent end of the wire to be attached to the inner surface of the winding drum. The wire rod is characterized by being folded down and pulled firmly into the hooking hole. By providing the fixing slit and the holding spring material near the bending axis, the winding start end of the wire rod is Bend it into an approximately Z shape, place one end of the approximately Z shape along the inner surface of the winding drum, lock the center in the N1 stopper hole, and automatically lock the other end along the outside surface of the winding drum. This type of wire rod hooking form has the advantage of stable hooking properties and a small rising height within the winding drum, thereby achieving the second objective.
