Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a method for processing the ends of a linear material in a winder.

(b) Conventional technology and its problems Conventionally, the end of the material wound on a bobbin that is set in a stringing machine for manufacturing lead wires used in electronic parts is affixed with a label to secure it so that the material does not unravel from the bobbin. In the former case, the label glue adheres to the material and prevents it from loosening, or by placing a presser collar on the bobbin collar and sandwiching the terminal between them. The latter has the drawback of being susceptible to dust adhesion and corrosion, and the latter method has the drawback of not being able to use existing bobbins.

(c) Means for Solving the Problems In view of the above problems, the present invention provides a method for winding a linear material by a preset number of windings onto a bobbin 48 connected to a spindle shaft 2 for rotating the bobbin in a winding machine. After wrapping the material around the spindle shaft 2 side of the bobbin 48 several times, with the bobbin 48 stopped by the brake mechanism B, a certain amount of the material for forming the knotted ring is wrapped so as not to loosen. After feeding, the material is wound in the opposite direction to the direction in which the material is wound around the bobbin 48 while applying an L-shaped claw 4 protruding from a suitable position of a spiral gear 3 pivotally mounted on the bearing of the spindle shaft 2 to the material at right angles. A twist ring (A) is formed by turning the ring only a few times.
Hook the twist claw 24 of the mold and attach the ring (A)
is removed from the above-mentioned Karage pawl 4, and then the twist pawl shaft 25 is rotated to twist the Karage ring (A) to prevent the ends of the wire-shaped material wound on the bobbin 48 from unraveling, and the above-mentioned This method eliminates the problems of the conventional method and enables efficient terminal processing of materials.

is raised and the friction wheel 41 provided at the tip thereof is brought into pressure contact with the material feed wheel 36 to rotate the feed wheel 36, and a certain amount of material for forming a knotted ring is sent out by the feed wheels 36 and 35, and the material being sent out is twisted. spring 3
After holding it so that it does not loosen using the tension lever 38 that pivots downward at the tension lever 9, it is slid until the upper limit adjustment piece 14 attached to the sliding rod 11 hits the guide arm 7 using the cam lever 8 in the locking mechanism A. While pulling down the moving rod 11 and hooking the material to the tip of the ratchet claw 4 as shown in Figure 4b, rotate the ratchet gear 3 in the direction of the arrow to move the bobbin 48 as shown in Figure 4c. A Karage ring (A) is formed in front of the right end of the frame, and the twist pawl base 23 is rotated via a connecting rod 33 that interlocks with the cam lever 32. ) with the twist claw 24, remove the Karage ring (A) from the Karage claw 4, and use the cam lever 29 to pull down the belt 31 that is stretched around the belt pulley 27 fixed to the twist claw shaft 25. Rotate the twist claw shaft 25, and rotate the twist claw shaft 25.
The twist pawl shaft 25 rotates three times until the gear 26 fixed thereto reaches the position where the teeth of the regulation gear 28 are embedded, as shown in Figure 4e, and the twist pawl shaft 25 stops turning. Twist the Karaage ring (A) and continue to connect the connecting rod 3 with the cam lever 32

The ends of the material removed from the bobbin 48 and wound onto the bobbin 48 as shown in FIG. 4f are treated so as not to unravel.

The bobbin 48, which has had its ends treated, is removed from the spindle shaft 2 and transferred to the next end cutting process.

It should be noted that even for resin-based materials, if heat is applied to the twisted part with the twisting claw and then the tool is cured, it can be used not only for metal materials but also for end treatment of resin-based materials.

(E) Effects of the Invention Since the present invention twists the end of the material as described above and deforms it so that it does not return to its original position, when the bobbin on which the material has been wound according to the present invention is attached to the lace making machine. If you pull the twisted and deformed terminal, it will easily untwist and you can quickly connect the materials, and unlike the terminals that are attached with labels, there will be no dust on the material. This eliminates the need for corrosion, does not cause corrosion, and allows the use of existing bobbins.

Furthermore, since the end processing of linear materials can be easily automated, great effects such as greatly improving productivity can be achieved.
