Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shield wire processing device, and more specifically, it separates and twists a long stripped shield wire, and measures it to a predetermined length. It is designed to be fed out and cut. [Prior art] In the past, it was considered impossible to automate the separation and twisting of long stripped shield wires, and everything was done manually. [Problem to be solved by the invention] However, according to such conventional examples, workability is poor and productivity is poor. *The product quality is not stable and the product is very expensive. The present invention was made in view of these problems and aims to provide a device with excellent workability. [Means for solving the problem] Therefore, the present invention is mechanized and automated,
The feature is that the tip of the shield part of the shield wire transported by the wire feeding device is held by a clamper, and by rotating the clamper, the core wire or the shield part of ε is separated and twisted. It is in.

[For production]

According to the present invention, the separation and twisting of the shield portion are performed simultaneously through a series of mechanical operations, thereby increasing the efficiency of the work. [Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.The tip of a core shield wire that had been stripped in advance was separated using a pair of rotating wire brushes, etc., and several millimeters of the tip of the core wire was cut off. (1) is held in the wire feeding device A shown in the first diagram, and separated and twisted device 1iB shown in the second and third diagrams.
Set it on the pair of clampers (4) and (5). The clampers (4) and (5) described above are rotated by a motor (6) via a pulley (7), a belt (8), etc. while holding only the shield portion. The clamper (405) is opened and closed by the cylinder (9). Also, the separation/twisting device is a cylinder (10)
By switching the spring (l1), the moving force when retreating is
A mechanism that allows adjustment is added as shown in the second and third figures. Next, to explain the specific configuration of the present invention, a pulse control motor (
A pair of rollers (14) rotated by

(Fig. 4) to strip the specified length. To further explain this shielded wire sheath strip assembly ffl (36), cutter holders (37) (38) are provided on the upper and lower sides.
) are arranged so that they can be approached or separated. vi. Cutters (39) and (40) are attached to the cutter holder, respectively, and these are moved by the driving device 1i (41). (42) is a guide and holder for the shield core (15). Next, the shield wire sent out for stripping is returned to a predetermined length by rotating the roller (14) in the opposite direction. Next, the tip of the stripped shield wire is straightened with a pair of rotating wire or plastic brushes (16).
(17) is lifted up and down to separate the shield wire (15a) and core IIA 05b). Furthermore, a few millimeters of the tip of the separated core wire is cut using a cutting device (19
) to cut. Furthermore, by reversing the roller (14) and moving it back several millimeters, the shield wire that has been raised up is returned to a horizontal state by the guide (20) of the wire feeder. Therefore, the tip of the stripped shield wire has a shape as shown in Figure 8, and the shield wire is several millimeters longer than the core wire. After performing these series of steps, the wire feeding device is further transported and set into the separating/twisting device shown in FIGS. 2 and 3. As shown in Figures 2 and 3, the separating/twisting device consists of a pair of clampers (4) and (5) that are opened and closed by an air cylinder (9), and a pulse control motor that rotates the clampers at a rotation speed that is proportional to the length of the strip. 6), etc., and a spring (11) for applying tension in the axial direction of the shield wire at the same time as rotation. A cylinder (10) is used for switching, and a cylinder (26) for horizontally moving these units is moved to a predetermined position in the wire feeding device (Fig. 1). Now, as shown in Fig. 1, the wire feeding device consists of a pair of rollers (14) that are rotated via a timing belt by a length-measurable motor such as a pulse control motor (13) that is capable of forward and reverse rotation. An air cylinder (23) for opening and closing the gap between the rollers (14), a stopper (27) provided on the shield wire guide (20) for fixing the entrance and exit of the shield wire, and an air cylinder for moving the stopper (27). 25). The separating/twisting device is horizontally moved by the cylinder (26) to a position where the tip of the shielded wire protrudes a predetermined length from the guide (20) of the wire feeding device. At this time, the stopper (27) stops only the shield wire at the tip of the shield wire in Fig. 4 at the position where it is held by the clampers (4) and (5). At this time, clamper (4) (
When the tip of the shield wire in 5) is clamped, it is desirable that it be several millimeters away from the tip of the core wire. After the separating/twisting device moves forward and clamps the shield wire as shown in FIG. 9 in the above manner, the roller (l)
4) is opened by the air cylinder (23), the air cylinder (25) moves back, and the stopper (27)
will be canceled. Next, the separating/twisting device uses the air cylinder (26) to pull out the retracted shield wire to a predetermined length. This length is determined so that the strip portion of the shielded wire is pulled out to an appropriate length from the guide (20) attached to the wire feeding device (Fig. 9). Separation/
After the twisting device has retreated by the predetermined length, the stopper (27) of the wire feeding device is activated by the air cylinder (26) to hold the shielded wire. Next, an air cylinder (1
0) retreats, and a predetermined tensile force is applied to the shield wire by the spring (11). This causes the shield wire and core wire to become further separated. Next, the clamper (4) (
5) The direction in which the shield wire is wound on the core wire is opposite to the direction in which the shield wire is wound on the core wire for a predetermined number of rotations.In other words, the shield wire is wound on the core wire in a left-handed manner.The shield wire is wound on the right by rotating the clamper in the right direction. By rotating the shield wire to the left, the shield wire separates on the core wire, and only the shield wire becomes twisted. The number of twists, direction, etc. can be freely set using a pulse control motor (6), etc., and the separation and twisting ratio can be adjusted according to the strip length of the shield wire.
A twisted state is obtained. After completing this series of separation and twisting operations, the air cylinder (9)
) (5) Open shield wire is opened. Next, the shield wire is discharged and cut by the wire feeding device I! (Fig. 10). As shown in Fig. 10, this discharge cutting device uses a shielded wire guide plate (30), one fixed V-shaped cutting blade (31), and two shafts (32) as guides to move the wire up and down. A moving V
It consists of a mold cutting blade (33), an air cylinder (34) that drives it, and a V-shaped guide (35) that holds the cutting position of the shield wire. Now, since the shielded wire conveyed by the electric wire feeding device tends to be conveyed with the tip part tilted considerably downward, the shielded wire is conveyed while being lifted by the guide plate (30), and the V-shaped guide (35) into. Next, the roller (14) of the wire feeding device is closed by the air cylinder (23), and the air cylinder (23) is closed by the air cylinder (23).
5), the stopper (27) is released, the pulse control motor (13) etc. is used to count and feed the required length, and the air cylinder (34) is used to cut the V-shaped cutting blade (33).
) to cut and discharge. Subsequently, the T-ray feeding device is fed to the predetermined position of the stripping device shown in FIG. 4, and the series of steps is completed (FIG. 9-1). In contrast to the long ones mentioned above,
If the shield wire to be supplied has been cut to a fixed size in advance, the shield wire may be discharged by moving it to a predetermined position in the stripping device after the separation/twisting step and rotating the roller (14) in reverse at a predetermined number of rotations. It is possible. [Effects of the Invention] According to the present invention as described above, the steps of stripping the shield wire, separating and twisting the shield wire, and cutting to size can be completely automated by simply inserting the shield wire into the device. This not only improves work efficiency, but also ensures uniformity of products, which in turn contributes to lower product costs.
