Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to winding of a wire start end at the start of winding and end of wire at the end of bobbin winding of various wires such as metal wires, synthetic resin wires, fiber threads, and ribbon wires made of metal. The present invention relates to a method for automatically winding a bobbin of a wire for connecting parts.

[0002]

2. Description of the Related Art Conventionally, as a method for winding a wire starting end portion in a bobbin winding machine for metal wires, the wire starting end portion is automatically adhered to a bobbin cylinder with an adhesive tape, and thereafter the metal wire is wound around the bobbin by rotating the bobbin. A method of taking the wire is known, and as a method of connecting the wire end portion at the end of winding, a method in which a worker manually connects the wire end portion with a Y-shape after stopping the bobbin has been adopted.

[0003]

By the way, generally, when a plurality of bobbins are respectively fed to a braiding machine to perform braiding, a wire breakage detecting device for detecting the tension drop of each wire and stopping the operation of the braiding machine. Is equipped with. Using such a braiding machine, when the desired braiding is performed by rewinding the wires from the plurality of bobbins wound by the above-described conventional wire start end winding method, when the desired braiding is completed, the bobbin wire that has been unwound quickly Will maintain the braid while receiving considerable tension in order to break away from the adhesive tape at the final end,
As a result, there are drawbacks such as unevenness in the braid, and when the wire end part separates from the adhesive tape, the wire end part bounces off and interferes with the work of connecting the wire end part in the next process. The manual Y-shaped knotting of parts causes a reduction in work efficiency in a winding machine for winding a large number of bobbins, and automation thereof has been eagerly desired.

The present invention provides a method for automatically winding a bobbin of a wire for winding the wire start end and tying the wire end so that the wire can be unwound to the final end without increasing the tension. Is an issue.

[0005]

As means for solving the above problems, the present invention is directed to a bobbin for winding a wire, a clipper for holding the wire outside the bobbin, and a clipper for holding the wire outside the bobbin. Then, using a binder composed of a wire hooking tube and a wire chuck portion provided at the tip thereof, and a traverse member located outside the clipper and the binder for guiding a wire from the outside, and supplied through the traverse member. With the start end of the wire being held by the clipper, the wire from the traverse member to the clipper is appropriately tilted with respect to the normal supply direction of the winding wire, and the bobbin is rotated in that state, and the clipper is rotated. Rotate around the bobbin at the same number of revolutions as the bobbin,
Spirally winding the inclined line around the bobbin a suitable number of times, and then inclining the line from the traverse member to the bobbin in the opposite direction to the inclined line, and in that state the bobbin and clipper as described above. The new slanted wire on the previous spiral winding wire in the opposite direction to the appropriate number of turns, and then the wire between the clipper and the bobbin. And then winding the wire by a regular traverse motion of the bobbin and the traverse member to wind a wire of a desired length, and after stopping the bobbin winding rotation. While the line extending from the traverse member to the bobbin is hung on the outer peripheral surface of the line-hanging cylinder, the binder is rotated almost once in the direction opposite to the bobbin winding-up rotation, and the line hung on the line-hanging cylinder is drawn. And then the binder is appropriately rotated in the same direction as the above, and a line from the traverse member to the bobbin is hung on the wire chuck part and the wire chuck part holds the wire. Along with holding the wire from the traverse member to the wire chuck portion with the clipper, next, the loop hooked on the wire hanging cylinder was removed from the wire hanging cylinder, and gripped by the wire chuck portion. Passing the wire into the removed loop, then cutting the wire between the clipper and the binder, and then rotating the bobbin by an appropriate angle in the winding direction to form the loop. Tighten, then release the wire grip of the wire chuck part of the binder, remove the full bobbin, and repeat the same process as above for a new bobbin. To propose a winding method of composed of line of the bobbin. Examples of the present invention will be described below.

As shown in FIG. 9 (C), the line (1) stretched between 4) and 4) is hung on the outer peripheral surface of the intermediate cylinder (41) as shown in FIG. The wire (1) hung on the intermediate tube (41) forms a loop. Then, the traverse roll (1
9) is moved to a position corresponding to the outer peripheral surface of the inner shaft (46), where the gear wheel (5) is further rotated in the same direction to draw a line on the outer periphery of the inner shaft (46). When the binder (22) reaches the pulling drive position and the clipper (21) reaches the open / close drive position (rotation by about 90 degrees) as shown in FIG. Therefore, first, the inner shaft (46) is retracted by the first-stage pulling drive of the tandem air cylinder (55) to chuck the wire (1) between the chuck plate (47) and the annular groove (42).

Then, the intermediate cylinder (41) and the inner shaft (46) are both retracted into the outer cylinder (40) by the second-stage traction drive of the tandem air cylinder (55), whereby the intermediate cylinder (41).
The loop that has been hooked on is removed from the intermediate cylinder (41), and the wire (1) chucked by the chuck plate (47) and the annular groove (42) is passed through the disconnected loop as shown in FIG. . Next, the nipper (60) is advanced by the advancing drive of the air cylinder (62), and the line (1) between the clipper (21) and the binder (22) shown in FIG. Then, the bobbin (14) is rotated clockwise by an appropriate angle to tighten the loop, and the intermediate tube (4) of the binder (22) is cut.
1) and the inner shaft (46) is advanced to release the end of the wound wire from the chuck of the binder (22).

[0021]

According to the wire bobbin winding method of the present invention, the wire starting end winding is started in a state where the clipper holds the starting end of the wire supplied from the draft member,
On the other hand, when the wire end tying is completed, the wire between the clipper and the binder is cut, and the wire start end winding start state in which the start end of the wire supplied from the traverse member is gripped by the clipper is prepared. As a result, the full bobbin can be removed, a new bobbin can be set at the winding position, and the wire start end winding can be immediately started.
It is possible to automate the bobbin winding of the wire that wraps the wire at the start of the wire and ties the wire at the end of the wire. The bobbin can be rewound to the final end of the rewind without increasing the tension as in the conventional case, and when various braids are made using a plurality of wound bobbins, the braid will be uneven. There is no need to give it, there is no danger of the final end of rewinding bouncing back, and it is possible to automatically tie the end of the wire in a Y shape, improving the efficiency of work in a winder equipped with multiple bobbins and performing simultaneous winding. It can be realized.
