[Coating Material Removing Step] Next, with the upper blade unit 518 and the lower blade unit 520 stopped at the above positions, the servo motor 312 is driven to move the front slider 301 to the set strip length SB.
2) Move it only backward (the length measuring device 100 side). At the same time, the servo motor 470 is driven to move the rear slider 404 rearward (on the side where the servo motor 470 exists) by the set strip length SA2 (time t).
Five). As a result, it is cut by the cutting unit 500 and separated.
Of the two coated wire rods 2, the coating material 2b at the cut end is peeled off.

[Crimping Terminal Attachment and Recovery Step] Next, the length measuring device 100 measures the length of the coated wire rod 2 for a single processing length and sends it to the wire loop portion 110 (time t6).

Next, the front side clamping portion 230 and the rear side clamping portion 26.
6, the crank arm 310 of FIG. 6 is rotationally driven while holding the coated wire rod 2 from which the coating material 2b on the front end side is peeled, and the lateral moving body 308 is moved to the crimping position of the front side crimping device 600 by the distance Y1. Slide horizontally (time t7).
Then, the crimp terminal is crimped to the core wire 2a from which the covering material 2b is peeled off (time t8). In addition, in synchronization with the slide of the lateral moving body 308, the lateral moving body 41 is moved by the rod end 418.
2 is driven laterally by a distance Y2 and the rear crimping device 60
The coated wire 2 guided to the crimping position 2 and sandwiched between the clampers 420 and 422 has the crimp terminal crimped to the portion of the stripped wire 2a of the coating 2b.

After this, the lateral moving body 308 and the lateral moving body 41
2 is returned to the original position, at the same time, the upper blade unit 518 and the lower blade unit 520 are separated from each other and returned to their original positions, and further, the front slider 301 and the rear slider 404 are returned to their original positions ( Time t9). Then, at this point, the front-side clamping unit 23 of the front-side moving device 300 is
0 and the rear side clamping unit 260, and the front and rear clampers 420 and 422 of the rear side moving device 400 are returned to their original positions. That is, the sandwiching of the covered wire rod 2 is released. To be more precise, the covered wire 2 clamped by the clampers 420, 422 is further laterally moved so as to be conveyed by the wire grasping mechanism of the discharging device 700 after the crimping terminals are crimped by the rear terminal crimping device 602. After sliding, clamper 42
The clamps 0 and 422 are released, and the wire rod gripping mechanism grips them and collects them in the collecting device 708.

Next, the covered wire material 2 sent to the wire spool section 110 between the times t5 and t6 is sent to the sending section 20.
2 is sent to a predetermined position of the front side moving device 300, and the tip of the covered wire rod 2 whose terminals are crimped by the front side crimping device 600 has upper and lower clampers 420, 4 of the rear side moving device 400.
It is sent to a position exceeding 22 intervals, and the state becomes the time t1. After that, by repeating the same operation as described above,
While the coated wire rod 2 is automatically cut into a fixed length, the coated wire rods 2b at both ends thereof are peeled off, crimp terminals are crimped to these portions, and are sequentially collected by the collecting device 708.

According to the above stripper apparatus 200, the upper and lower blade units 518 and 520 are moved up and down, the forward and backward movements of the front slider 301 and the backward and forward movements of the rear slider 404 are performed in the conventional manner. Unlike the stripper device, since it is performed by a servo motor, the front slider 301 and the rear slider 4 are associated with the vertical movement of the upper blade unit 518 and the lower blade unit 520.
The operation of 04 can be controlled arbitrarily. Therefore, after the upper and lower cutters 522, 530 of the upper blade unit 518 and the lower blade unit 520 cut the covered wire rod 2, the upper and lower strip cutters 526, 534, 524, 53
2 before the biting of the end of the covered wire rod 2, that is, between the times t2 and t3 in FIG.
By adjusting the distance SB1 for moving 01 and the distance SA1 for moving the rear slider 404, the covered wire 2
The strip length at the end of can be easily changed. Therefore, when changing the strip length, remove the upper blade unit and lower blade unit and adjust the intervals of the front strip cutter, the cutter, and the rear strip cutter as before, or re-install them, or It is no longer necessary to replace the adjusted upper blade unit and lower blade unit with each other, so that a great amount of labor required for changing the strip length can be eliminated and the working efficiency can be remarkably improved.

According to the stripper device having the above structure, the end portion of the covering material 2b is stripped by the strip length Ls as shown in FIG. 20 without adding any mechanical mechanism to the above structure. It is possible to perform a semi-strip operation in which the strip portion 2bs is left at the end of the wire 2a.

FIG. 19 shows a timing chart similar to FIG. 18 when the semi-strip operation is performed. As is clear from the figure, when performing the semi-strip operation, after the upper blade unit 518 and the lower blade unit 520 are engaged to the position where the coating material 2b of the coated wire rod 2 is cut, the front slider 301, The semi-strip cutters may be separated from each other before the rear slider 404 is completely separated.

As described above, according to the stripper apparatus of this embodiment, the upper blade unit 518 and the lower blade unit 5
20 ascending / descending operation, front slider 301 and rear slider 4
Since the operation of 04 can be controlled arbitrarily, FIG.
The length of the semi-strip portion 2bs and the strip length Ls can be arbitrarily adjusted and changed, and workability and productivity are significantly improved as compared with the case where the semi-strip operation is performed by the conventional stripper device.

Therefore, when setting the crimping position, move the covered wire rod 2
The position is unlikely to be misaligned with respect to the direction, and the crimping position is accurate and
It can be adjusted and set with high accuracy .

[0060] The present invention is upper blade unit and elevation drive unit to perform the lifting operation of the lower blade unit, the rear side of forward and backward driving in the feeding direction of the front drive unit and the rear slider forward and backward driving the front slider in the feed direction It is characterized by the structure of the drive portion, and the configuration of the other portions is not limited to the above embodiment, and the design can be changed as appropriate.

[0061]

As described above, according to the present invention, the elevation drive unit, the front drive unit and the rear drive unit respectively rotate the servomotor and the output shaft of the servomotor in the forward and reverse directions. Since the structure is provided with the motion converting unit that converts into a linear motion, the operations of the front slider and the rear slider can be arbitrarily controlled in correspondence with the lifting operation of the upper blade unit and the lower blade unit. Therefore, the strip length can be easily adjusted by adjusting the amount by which the front and rear sliders are moved after the upper and lower cutters cut the coated wire and before the upper and lower strip cutters bite the ends of the coated wire. The strip length can be changed, and the great effort required to change the strip length in the past is not required, and the working efficiency can be significantly improved.
