  In the above-described wire film peeling apparatus, the movement of the cutter lever in the closing direction is regulated so that the cutter bite into the wire is constant by the adjusting screw that contacts the rear end of the cutter lever. It is difficult to control the force that presses the cutter against the wire because the centrifugal force and the biasing force of the spring due to the rotation, such as the distance from the rotation shaft of the drive device and the rotation speed of the rotation shaft, must be considered. There was a risk of damaging the core material inside the coating.

  The present invention solves the above-described problems, and provides a wire coating film peeling apparatus that enables control of the force pressing a cutter (peeling blade) against a wire material and suppresses damage to the core material in the inner part of the coating film. The purpose is to do.

When the shaft rotates, the movable piece rotates due to the centrifugal force of the rotation of the support shaft, and each peeling blade moves away from the axis of the support shaft, and the coil is excited, so that the movable core becomes a fixed core. When approaching, the slidable contact portion and the abutting portion are slidably contacted and the movable piece is rotated, whereby each peeling blade moves to the axis side of the support shaft.

  According to this, it is possible to adjust the amount of movement of the movable core by adjusting the angle of the sliding contact portion of the movable core with respect to the axis of the support shaft, the position and shape of the contact portion, and accordingly the movable piece Since the amount of movement can also be adjusted, it is possible to control the force for pressing the peeling blade against the wire, and it is possible to suppress damage to the core material in the inner part of the coating.

  If the solenoid is a proportional solenoid, in addition to the above effects, it is possible to adjust the amount of movement of the movable core by adjusting the current, and accordingly the amount of movement of the movable piece can also be adjusted. The accuracy of controlling the force for pressing the peeling blade against the wire can be increased.

  In addition, when the peeling blade is formed in a flat plate shape and is disposed so as to be inclined with respect to a plane perpendicular to the axis of the support shaft when peeling the coating of the wire, the peeling blade is formed on the coating of the wire. Since the corners are easy to hit, the coating can be easily peeled off.

  Further, if the peeling blade has a guide portion for guiding the wire when peeling the coating of the wire, the movement of the wire can be restricted and the peeling operation of the coating can be stabilized.

  Further, if a biasing member that biases each peeling blade attached to the movable piece away from the axis of the support shaft is disposed on the movable piece, the driving device is not driven to rotate the support shaft. The movable piece can be arranged at a position away from the axis of the support shaft.

When the movable iron core 77 approaches the fixed iron core 71, as shown in FIGS. 3 and 8 (b), the outer peripheral surface of the sliding contact portion 77b and the contact portions 50c and 51c come into sliding contact with each other, and the movable piece 50, 51 rotates.

  Since the sliding contact portion 77b has a truncated conical shape that expands toward the front side, the contact portions 50c and 51c move away from the axis C of the support shaft 40 when the movable iron core 77 moves to the front side. Accordingly, the front side where the peeling blades 60 and 61 of the movable pieces 50 and 51 are disposed approaches the axis C of the support shaft 40. That is, it approaches the inserted wire W.

  The peeling blades 60 and 61 are 80 degrees to the axis C of the support shaft 40 in a side view as shown in FIGS. 10A and 10B in the state of peeling the coating F of the wire W shown in FIG. It is arranged so as to be inclined by 85 degrees. Thereby, it is possible to improve the peelability of the coating F by causing the corners of the peeling blades 60 and 61 to contact the wire W while the peeling blades 60 and 61 are pressed against the wire W.

  Further, the peeling blades 60 and 61 are inclined by 1 to 20 degrees with respect to the axis C of the support shaft 40 in a plan view as shown in FIG. 11 in a state where the coating F of the wire W shown in FIG. 2 is peeled off.

And a sliding contact portion 77b formed in a truncated cone shape extending toward the side. The sliding contact portion 77b is fitted to the outside of the support shaft 40 and slid along the axis C direction of the support shaft 40 with respect to the support shaft 40. The movable pieces 50 and 51 are formed to be movable along the axis C of the support shaft 40 and arranged around the axis C of the support shaft 40 as viewed from the direction of the axis C of the support shaft 40. The separation blades 60 and 61 are disposed at the ends of the movable pieces 50 and 51 on the side away from the fixed iron core 71 with the axis S of the movable pieces 50 and 51 interposed therebetween. 50 and 51 are provided with contact portions 50c and 51c that are slidable in contact with the outer peripheral surface of the slidable contact portion 77b at the ends of the fixed iron core 71. When the support shaft 40 is rotated by the electric motor 31, the support shaft 40 is provided. The movable pieces 50 and 51 are rotated by the centrifugal force of the rotation. When the peeling blades 60 and 61 move away from the axis C of the support shaft 40 and the coil 76 is excited, when the movable iron core 77 approaches the fixed iron core 71, the sliding contact portion 77b is brought into contact with it. When the parts 50 c and 51 c are in sliding contact with each other and the movable pieces 50 and 51 are rotated, the peeling blades 60 and 61 are moved to the axis C side of the support shaft 40.

  According to this, the amount of movement of the movable iron core 77 can be adjusted by adjusting the angle of the sliding contact portion 77b of the movable iron core 77 with respect to the axis C of the support shaft 40 and the positions and shapes of the contact portions 50c and 51c. Accordingly, the amount of movement of the movable pieces 50 and 51 can be adjusted accordingly, so that the force for pressing the peeling blades 60 and 61 against the wire W can be controlled, and the core M of the inner part of the coating F can be controlled. Can be suppressed.

  Further, since the solenoid is a proportional solenoid 70, in addition to the above effects, it is possible to adjust the amount of movement of the movable iron core 77 by adjusting the current, and accordingly the amount of movement of the movable pieces 50 and 51 can be adjusted. Therefore, the precision of control of the force which presses the peeling blades 60 and 61 against the wire W can be improved.

  In addition, when the peeling blades 60 and 61 are formed in a flat plate shape and the coating F of the wire W is peeled off, the peeling blades 60 and 61 are arranged so as to be inclined with respect to the plane orthogonal to the axis C of the support shaft 40. Since the corners of the peeling blades 60 and 61 are likely to hit the coating F of the wire W, the coating F can be easily peeled off.
