Description

TECHNICAL FIELD The present invention relates to an insulator stripping device for a cabtire cord or a cabtire cable, and more specifically, with a cabtire cord or a cabtire cable, an insulator can be stripped without loosening a twisted core. Relates to the device to perform. The cab tire cord or cab tire cable is hereinafter referred to as an insulated wire.

  Conventionally, an insulated wire has been processed with a peeling device by unscrewing the twisted wire cores with fingers and holding the finger wires so that the wire cores do not overlap with each other.

However, in the above method, the positions of the wire cores are not stabilized, the wire cores overlap each other, and when the upper and lower stripping blades bite into the insulator, the copper wires on one or both sides of the wire cores may be cut. there were. Furthermore, since the work of loosening the wire core is performed with a human fingertip, the skin is irritated and painful due to friction, which is severe for long-time work.

  Accordingly, an object of the present invention is to remove the wire core insulation in a surely fixed state, instead of the uncertain fixing of the wire core that relies on the human fingertip as described above. Is to provide.

  The insulation stripping device for the insulated wire core according to the present invention includes an insulated wire fixture for securing the insulated wire and an insulated wire fixed by the insulated wire fixture when stripping the insulation of the wire core. Grip the wire core while applying a predetermined pressure and rotate it in the direction opposite to the twisted direction to rotate it back, or apply vibration while holding the wire core of the insulated wire while applying a predetermined pressure. A twisting arm that loosens the wire cores in a horizontal row and a stripping blade that peels off the insulator when the wire cores are in a horizontal row.

  ADVANTAGE OF THE INVENTION According to this invention, the peeling apparatus which can perform the insulator stripping process of a wire core in a fixed state reliably is obtained. In particular, in the present invention, the twisted core of the insulated wire is automatically loosened, and the work can be simplified because it can be peeled off, and the manual work of loosening the core or holding it in a horizontal row is not necessary. It can be handled even if you are not a skilled worker. Moreover, machining accuracy is remarkably improved by not performing machining in a state where the wire cores overlap each other.

It is the schematic which shows the whole peeling apparatus of this invention. It is a figure which shows the process of the peeling process of this invention. It is an enlarged view for demonstrating the principal part of the stripping process of this invention.

  First, referring to FIG. 1, an insulator stripping device for a wire core of an insulated wire includes an insulated wire fixture 1 for fixing the insulated wire, a positioning plate 2 at the tip of the wire core, and the positioning plate 2. Oppositely, for example, a twisting arm 3 composed of two arms arranged up and down to unwind the wire cores and arrange them in a horizontal row. It has a peeling blade 4 composed of a blade, a twist arm 3, and a movable part 5 that can move the peeling blade 4.

  Here, the insulated wire fixing tool 1 is provided with a position adjustment bolt (not shown) that can adjust the center of the insulated wire when the thickness of the insulated wire is changed, and has versatility. Yes. The position of the positioning plate 2 can be adjusted. The positioning plate 2 can be fixed by moving to the left or right in the drawing, and the stripping length can be changed. In addition, the two opposing arms of the twist arm 3 are subjected to a predetermined pressure in a direction in which the gap is narrowed in a state where the insulated wire is clamped (gripped), and the wire cores are arranged in a horizontal row while the wire cores are being loosened. Work the power to do. The twist arm 3 is provided with a sensor (not shown) for detecting the distance between the two arms when the wire core is gripped to a position where the wire cores are in a horizontal line and the state is reached. Further, the distance between the two opposing blades of the peeling blade 4 can also be adjusted according to the size of the wire core.

  Next, with reference to FIG. 2, the process of the wire core insulator stripping apparatus will be described. As shown in FIG. 2a, the insulated wire is inserted into the insulated wire fixture 1 until reaching the tip of the positioning plate 2 (arrow A), and is fixed by the insulated wire fixture 1 (arrow B).

Next, as shown in FIG. 2b, the wire core of the insulated wire is clamped by two arms of the twist arm 4 (arrow C), and in this state, a predetermined pressure is applied to the two arms in a direction of narrowing the interval.

  Next, as shown in FIG. 2c, the twisting arm 4 holding the wire core is rotated in a direction opposite to the twisted direction. At this time, the wire core rotates while being loosened, and loosens when reaching a position of about 90 degrees, for example, as shown in FIG. 2d.

  Next, as shown in FIG. When the rotation and the rotation return are repeated, the overlapping wire centers become a horizontal line. A state in which the wire cores are in a horizontal row is detected by a sensor (not shown).

  Next, when the sensor detects a horizontal line state of the wire core, as shown in FIG. 2f, the two blades of the peeling blade 4 bite into the insulator so as to peel only the insulator of the wire core from above and below (arrow D). ).

  Finally, the twisting arm 3 and the peeling blade 4 are simultaneously moved in the direction of arrow E to peel off the insulator.

  FIGS. 3a to 3d are enlarged views corresponding to FIGS. 2b to 2e, and show an enlarged view of a process in which the wire cores are arranged in a horizontal row.

(Other embodiments)
In the above-described embodiment, the configuration in which the twisting arm rotates and returns and the wire cores are arranged in a horizontal row has been described, but instead of rotating and rotating back, vibration is applied to the twisting arm that grips the wire core, The twist of the heart may be loosened and arranged in a horizontal line.

Next, as shown in FIG. 2b, the core of the insulated wire is clamped by the two arms of the twist arm 3 (arrow C), and in this state, a predetermined pressure is applied to the two arms in a direction of narrowing the interval.

Next, as shown in FIG. 2c, the twist arm 3 holding the wire core is rotated in a direction opposite to the twisted direction. At this time, the wire core rotates while being loosened, and loosens when reaching a position of about 90 degrees, for example, as shown in FIG. 2d.
