The clutch gear 32 is coaxially fitted to the outer periphery of the screw shaft 29. and is rotatably supported by a movable frame 4. For this reason, the clutch gear 32 is a state in which the screw shaft 29 idles around the outer periphery of the non-threaded portion 29b or 29c. , a state in which it engages with the square screw portion 29a and moves laterally while rotating can be obtained. ing.

[0016] The screw shaft driven air cylinder 33 is a cylinder supported by the bracket 3a. The main body 34 and the cylinder which is incorporated in the cylinder main body 34 and presses the screw shaft 29. It is equipped with a piston 35 to operate and a return coil spring 36 to return the piston 35. It is designed with a focus on

[0017] In addition, the movable frame 4 and the rotating body 6 have a C-shaped rotating body main body of the rotating body 6. 6a and each opening of the C-shaped gear main body 12a of the rotor drive gear 12 is shown in FIG. A circuit for controlling the rotating body 6 to stop it when it is facing outward as shown in A rolling body stop position regulating mechanism 37 is provided. The rotating body stop position regulating mechanism 37 is In the state shown in FIG. , which is normally inside the movable frame 4 and is inserted into the recess 38 when the movable frame is stopped. A stopper 39 disposed astride the frame 4 and the rotating body 6, and a stopper 39 installed in the movable frame 4. Stopper operating air as a stopper operating tool that operates the stopper 39 The cylinder 40 is configured to include a cylinder 40.

[0018] Next, the operation of such an insulated wire stripping device will be explained.

[0019] In the rotating body main body 6a of the rotating body 6 which is stopped in the state shown in FIG. 2 and the opening is open, The electric wire penetration part 9 and the electric wire penetration part in the gear main body part 12a of the rotating body driving gear 12 13, fit and set the insulated wire to be stripped.

[0020] In this state, actuate the complementary part operation air cylinder 15 of the complementary part closing mechanism 14 and operate it. Push out the arm 16. This action causes the operating arm 16 to center the pin 17a. The center is rotated counterclockwise in Figure 2, and in the process of rotation, the closing operation lever is first rotated. The roller 18 hits the complementary portion 6b of the rotating body 6 and presses it. Complement with this pressing operation The portion 6b is rotated counterclockwise in FIG. 2 about the pin 7, and the rotating body portion 6a It fits into the opening and becomes circular as a whole.

[0021] As the complementary part 6b rotates, the cutting edge of the cutter 11 cuts into the insulation coating of the insulated wire. Get into it.

[0022] Further, as the complementary portion 6b rotates, the torsion coil spring 8 is charged with force, and later It stands by in preparation for the automatic opening operation of the complementing section 6b to be performed.

[0023] Furthermore, as the complementary portion 6b rotates, the complementary portion 12b of the rotating body drive gear 12 also rotates. The gear is rotated together and fitted into the opening of the gear main body 12a, and the whole becomes circular. .

[0024] In this state, the opening prevention roller 19 hits the outer periphery of the complementary part 6b, and the complementary part 6b This prevents the portion 6b from opening.

[0025] If this condition occurs, operate the stopper operation air cylinder 40 to stop the stopper. The pad 39 is removed from the recess 38 of the rotating body 6, and the rotating body 6 is made rotatable.

[0026] Next, the air motor 20 is rotated. The rotation of this air motor 20 is for the rotating body. The rotational force is applied to the rotating body 6 via the rotational force transmission mechanism 21, and the rotating body 6 rotates around the insulated wire. The cutter 11 also rotates around the outer circumference of the insulated wire, cutting off the insulation coating with its cutting edge. Cut in the circumferential direction. Even while the rotating body 6 is rotating, the opening prevention roller 19 Since it rotates by pressing while contacting the outer periphery of the rotating body 6a of the complementary part 6b, Prevent it from coming off.

[0027] Note that at this time, the clutch gear 32 is connected to the threadless portion 29b of the screw shaft 29. Since the movable frame 4 is idling on the outer periphery, the movable frame 4 is not moved laterally.

[0028] When the cutter 11 has finished cutting the insulation coating in the circumferential direction, the screw shaft operating air The cylinder 33 is operated to push out the screw shaft 29. This will cause the return coil to The spring 36 is compressed and stored, and the square threaded portion 29a of the screw shaft 29 is The movable frame is screwed into the screw hole of the clutch gear 32, and as the clutch gear 32 rotates. Frame 4 is gradually moved to the left in FIG. Therefore, the rotating body 6 is made of insulated wire. The cutter 11 is moved to the left in FIG. 1 while rotating together with the cutter 11. The insulation coating of the insulated wire is torn in a spiral shape by the cutting edge of the insulated wire.

[0029] In this case, the lateral feed of the cutter 11 is carried out on the screw shaft in synchronization with the rotation of the rotating body 6. Since the thread pitch of the square screw part 29a of 29 is constant, the stripping width of the insulation coating is becomes constant, the mechanical strength of the stripped string-like body becomes constant, and the insulation You can strip the skin without wrapping it around the wire.

[0030] The clutch gear 32 is disconnected from the screw connection at the left end of the square screw part 29a, and there is no screw. When reaching the part 29c, the clutch gear 32 becomes idle again, and the movable frame 4 And the lateral feeding of the cutter 11 is stopped. In this state, the cutter 11 is still disconnected. As it continues to rotate around the outer circumference of the edge wire, its cutting edge cuts the insulation coating in the circumferential direction. When this state is reached, the stripping of the insulated wire is completed. If such a situation occurs , the extrusion of the screw shaft 29 by the screw shaft operation air cylinder 33 is stopped. let As a result, the screw shaft 29 is biased by the return coil spring 36 as shown in FIG. Moved to the left and returned to the original position.

[0031] Next, operate the stopper operating air cylinder 40 to move the stopper 39 to the rotating body 6 side. The air motor 20 is rotated while being energized. Then, the rotating body 6 has its outer circumference When the recess 38 is in the rotational position facing the stopper 39, the stopper 39 is in the recess 38. This causes the rotary body 6 to stop rotating. In this state, the air motor 20 rotates. to stop.

[0032] At this stop position, the opening of the C-shaped rotating body main body 6a of the rotating body 6 is It is facing outward as shown. Therefore, disconnection from the wire penetration portion 9 which will be performed later. It becomes possible to take out the rim wire without any trouble.

[0033] When the rotation of the rotating body 6 is stopped, the complementing part operation air switch of the complementing part closing mechanism 14 is activated. The cylinder 15 is operated and the operating arm 16 is moved back. This prevents it from opening. Since the roller 19 is separated from the complementary part 6b and the pressing force is removed, the complementary part 6b and the complementary part 6b are removed. The complete part 12b rotates clockwise in FIG. 2 around the pin 7 due to the action of the torsion coil spring 8. The rotating body 6a and the gear main body 12a are both opened. Therefore , the insulated wire that has been stripped can be taken out from the wire penetration parts 9 and 13.

[0034] After removing the insulated wire from the wire penetration parts 9 and 13, operate the complementary part closing mechanism 14. By the same operation as described above, the complementary parts 6b and 12b are connected to the rotating body body part 6b and the gear body part 1. 2a, and operate the stopper operating air cylinder 40 to move the stopper 39 backward. Then, the rotating body 6 is made free, and the air motor 20 is reversely rotated. This operation allows you to The gear 32 is reversely connected to the square threaded portion 29a of the screw shaft 29, and The moving frame 4 is traversed to the right in FIG.

[0035] The clutch gear 32 is unscrewed at the right end of the square threaded portion 29a, and the threaded connection is removed. The movable frame 4 returns to the state of idling at the stop portion 29b and returns to its original position.

[0036] In this state, operate the stopper operating air cylinder 40 again to close the stopper 39. The rotating body 6 is biased toward the rotating body 6, and the rotating body 6 is biased toward the rotating body 6 with the opening of the rotating body main body 6a facing outward. The rotation of the machine is stopped, the complementary parts 6a and 12b are opened, and the machine is on standby in preparation for the next peeling operation. let

[0037] In addition, each cylinder 15, 33, 40 is not limited to an air cylinder, but can also be a liquid cylinder. It can also be used. In addition, the complementary part operation consisting of these cylinders 15, 33, and 40 is As a cutting tool, screw shaft operating tool, and stopper operating tool, a solenoid is used instead of a cylinder. ID etc. can be used.

[0038]
