0002

2. Description of the Related Art Generally, a drawn wire or the like is wound around a bobbin of a winding machine, and the wire is cut when the drum is fully wound.

Conventionally, the terminal end of the filament wound on the bobbin is passed through a wire hooking hole drilled in the flange of the bobbin, or the terminal end of the filament wound on the bobbin is passed through a wire hooking hole drilled in the flange of the bobbin, or the terminal end of the filament wound on the bobbin is passed through a wire hooking hole formed in the flange of the bobbin. It was fixed by pasting adhesive tape on top.

0004

[Problems to be Solved by the Invention] Therefore, in the above-mentioned conventional method, the terminal processing must be carried out by the operator, which is troublesome, and furthermore, when using adhesive tape, the terminal processing must be done by the operator. Another drawback was that the adhesive tape remained on the surface. If there is any residual glue, there is a risk that the filament will discolor during the next annealing process, resulting in quality defects.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an end processing device for a winding machine that can be unmanned and does not leave adhesive tape residue behind.

A second locking member whose claw part enters into a protruding part of the filament body between the member and removably locks the filament body; an actuating mechanism for intruding into the striated body protrusion; and a rotation mechanism for rotating the second locking member in the striated body locked state around its axis and twisting the striated body protruding portion to form a narrowing section. A first cutting mechanism that cuts the tip of the narrowing section, and a second cutting mechanism that cuts the filament between the narrowing section and the traverse guide.

[0007]

[Operation] In the fully wound state, the first locking member is operated by the reciprocating mechanism to lock the filament body to the first locking member, and wind the filament body around the bobbin and the locking member. . Then, the claw portion of the second locking member is caused to enter the protruding portion of the filament body formed in this state using the actuating mechanism, and the filament body is locked in the claw portion of the second locking member. Next, the first locking member is moved by the reciprocating mechanism to release the locked state. Thereafter, the second locking member in the filament-locked state is rotated around its axis by a rotation mechanism, the filament body protrusion is twisted to form a narrowed part, and the narrowed part is made into a first cut. Along with cutting by the mechanism,
The striatum is placed in the second position between the narrowing part and the traverse guide.
When the cutting mechanism cuts the filament, the processing of the terminal end of the filament is completed.

[0020]The first locking member 2 is provided with a protrusion/retraction holding mechanism which is a publicly known technology used in ballpoint pens and the like. That is, by pressing the first locking member 2 in the direction of arrow B against the elastic force of the elastic member 30, the hook portion 2
b is held in that state when it is protruded, and when the first locking member 2 is further pressed in the direction of arrow B, the holding state is released and the first locking member 2 becomes elastic. It is pressed in the direction of arrow A by the elastic force of the generating member 30 and enters the retracted state.

[0021] As shown in FIG. 2, the filament W is caught on the hook 2b. In other words, it will be caught on the leaf spring 26, and from this state, the first locking member 2 can be pulled in the direction of arrow B as shown in FIG. 3 without moving the filament W in the direction of arrow A. If so, the leaf spring 26 is pressed by the filamentous body W, swings in the direction of arrow C, and the filamentous body W

Therefore, when the slide body 34 moves in the axial direction as shown by the arrow C, the protrusion 39 will fit into the recess 38, and in this case, the filament body W will be removed as shown by the imaginary line. If interposed between the flanges 34b and 17b, the filamentous body W is held between the outer flanges 34b and 17b, and in this state, the filamentous body W is cut by the cutter 36.

Further, as shown in FIG. 1, this second locking member 5 is connected with a rotation mechanism 9 for rotating it around its axis. That is, the rotation mechanism 9 includes a pivot portion 50 that rotatably holds the second locking member 5 around its axis via a bearing 54 (see FIG. 6), a motor 51, and a driving force of the motor 51. It is equipped with a reducer 52 and gears 53, 53 for transmitting data to the second locking member 5, and a motor 5.

The speed reducer 52 and the pivot portion 50 are attached to the holding plate 55 via fixing members 71 and 72, respectively.

Therefore, the holding plate 55 is connected to the above-mentioned operating mechanism 7.
This causes the second locking member 5 to also operate.

Further, the frame 60 is provided with a holding piece 67, the cylinder main body 57a is attached to the holding piece 67, and the holding plate 55 is attached to the piston rod 57b of the cylinder 57.
A connecting body 68 protruding from the connecting body 68 is connected.

Therefore, the piston rod 5 of the cylinder 58
8b is extended from the state shown in FIG. When the piston rod 58b is retracted, the arm 63 swings about the pivot shaft 69, and the second locking member 5 swings in the direction of arrow J.

[0038] Also, the piston rod 57 of the cylinder 57
When b is extended, the holding plate 55 slides in the direction of arrow G, the second locking member 5 moves forward, and conversely, the piston rod 57b
If it is retracted, the holding plate 55 slides in the direction of arrow H and the second locking member 5 retreats.

Next, a method of using the terminal processing device configured as described above will be explained.

First, as shown in FIG. 9, when a full winding state is reached, a full winding signal from a detector (not shown) that detects a full winding state is used to reduce the feeding speed of the filament W, and the traverse is stopped. The guide 11 is stopped at the fixed position shown by the solid line in FIG.

At this time, the piston rod 32b of the cylinder 32 is extended, the sliding contact plate 31 is brought closer to the bobbin 1, and the first locking member 2 is pushed out in the direction of arrow B. In other words, the first locking member 2 is brought out onto the pass line.

[0042] In this state, the bobbin 1 is further rotated to wind two to three lines of the filament W around the first locking member 2, and then the rotation of the bobbin 1 is stopped. Therefore, in this case, as shown in FIG. 10, the filament W is wound around the bobbin 1 and the first locking member 2 to form the filament protrusion 4. That is, in this state, the filament W is caught on the leaf spring 26 of the first locking member 2, as shown in FIG.

Next, the piston rod 58 of the cylinder 58
b is extended and the holding plate 55 is swung in the direction of the arrow I to bring it into the state shown in FIG. Thereafter, the piston rod 57b of the cylinder 57 is extended, the holding plate 55 is slid in the direction of the arrow G, and the claw portion 6 of the second locking member 5 enters into the filament projection portion 4. Next, as shown in FIG. 5, the second locking member 5 is swung in the direction of arrow J via the cylinder 58, and
The second locking member 5 is moved in the direction of the arrow H via the cylinder 57, and the filament body W is locked with the claw portion 6, resulting in the state shown in FIG.

After that, the sliding contact plate 31 is moved through the cylinder 32.
is moved slightly in the direction of arrow B to release the first locking member 2, and then the sliding contact plate 31 is moved in the direction of arrow A,
The first locking member 2 can be retracted.

At this time, since the filament W is locked to the second locking member 5, if the first locking member 2 is retracted as shown by arrow A as shown in FIG. 26 swings as shown by arrow C, and the filament body W is unlocked.

Next, in this state (that is, the state shown in FIG. 12), the second locking member 5 is rotated around its axis via the rotation mechanism 9, and the filament protrusion 4 is twisted. Figure 1
This results in a narrowing down section 8 as shown in 3.

At this time, as shown in FIGS. 6 to 8, the first
The cutting mechanism 10 cuts the tip of the narrowing part 8. On this occasion,
Due to the ejection mechanism 48, no residual filament remains in the cutter 46.

After that, the traverse guide 11 is moved to the position shown by the imaginary line, and the striated body W is moved between the outer flange 17b of the holding member 17 and the slide body 3 as shown by the imaginary line in FIG.
In this state, the slide body 34 is slid in the direction of arrow C to chuck and cut the filament body W. That is, the second cutting mechanism 12 cuts the filamentous body W at the X portion shown in FIG. 13 .

Therefore, according to this device, a series of these terminal processing operations can be performed automatically and reliably.
