Abstract

(57) [Abstract] [Purpose] When stripping the insulation of multi-core insulated core wire, prevent dust from falling on the worker. [Structure] A hood 8 covering the insulating core a insertion port 3 is provided on the front surface of the casing 1, and a dust collector 7 is connected to the hood 8. When the dust collector 7 is driven, an air curtain is formed below the opening of the hood 8. The insulated core wire a ′ of the cable end a pulled out from the drum is inserted into the insertion opening 3 of the apparatus A by moving itself A through the universal caster 5 and held by the chuck pieces 12a and 12b. Then, the insulator of the insulating core wire a ′ is peeled off. At this time, most of the stripped off insulator scraps fall into the box 4, while
The dust soared flows out from the insertion port 3, but is blocked by the air curtain and sucked into the hood 8. For this reason, the degree of dust falling on the worker is minimized.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device for stripping the insulation of the insulation core wire for a characteristic test such as a disconnection / mixed wire test of a communication cable, etc. The present invention relates to a device for removing a body.

[0002]

[Prior art and its problems]

 The applicant has proposed various insulation stripping devices for multi-core insulation core wires, as disclosed in Japanese Patent Publication No. 56-23362, Japanese Patent Publication No. 56-24444 and Japanese Patent Publication No. 56-24445.

As shown in FIG. 5, the stripping work by this device is performed by placing a drum D around which a cable is wound by a hawk lift or the like on an inspection table B, and pulling out the cable end a from the drum D. Strip the required length by a stripping machine (not shown), insert the exposed multi-core insulating core wire a'into the above-mentioned device A, and use a rotating brush to remove the insulator of each core wire a '. Strip off.

However, in this conventional device, a dust collector is provided to suck the dust in the casing, but since the intake port is behind the rotary brush, the dust is not smoothly absorbed, Dust spilled out of the casing, deteriorating the working environment. In particular, the dust spilled from the multi-core insulated core wire a'insertion port directly falls on the worker, which is a problem.

Therefore, in view of the above points, the present invention has an object to prevent dust from falling on an operator.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides the above-described insulator stripping apparatus, in which a dust collector is provided in the casing and a hood covering the multi-core insulated wire insertion port is provided on the front surface of the casing. It adopted a configuration in which the intake port was exposed to the inside of the hood.

[0007]

[Action]

 In the insulator stripping device according to the present invention configured as described above, first, as in the conventional case, first, the insulating core wire of the cable end is inserted into the rotating brush from the insertion port. In this state, rotate the rotating brush to peel off the insulation of the core wire.

At this time, most of the scraps of the stripped insulator fall into the box. On the other hand, dust rises above the rotating brush and tries to flow out from the insertion port to the worker side, but the insertion port is covered by the hood, the intake port faces it, and the dust is smoothly absorbed. There is no dust on it.

【Example】

 In the embodiment shown in FIG. 1, similar to the one described in Japanese Patent Publication No. 56-23362, a cylindrical wire brush 2 is provided in a pair in a casing 1, and an insulating core wire a ′ is inserted into the insertion port 3 From between the two brushes, and the brush 2 is rotated by a motor (not shown) to peel off the insulator.

Arms 11 are provided on both sides of the insertion opening 3 via brackets 10, and fixed chuck pieces 12 a are fixed over the upper ends of both arms 11. An air cylinder 13 is integrally provided on the arm 11, and a movable chuck piece 12b is fixed to the upper end of the ram. The air cylinder 13 keeps the movable chuck piece 12b parallel to the fixed chuck piece 12a. Go back and forth. Air is supplied from the compressor C to the air cylinder 13.

As shown by the chain line in the figure, the chuck mechanism is first tilted toward the front to separate and flatten the insulating core wire a ′ of one unit, between the chuck pieces 12a and 12b, and the insertion opening. After reaching the wire brush 2 through 3, the movable chuck piece 12b is moved and chucked. In this state, the wire brush 2 is rotated, the arm 11 is gradually raised like a solid line, and the insulating core wire a'is fed into the wire brushes 2 and 2 to peel off the insulator. The operation of the wire brush 2 and the air cylinder 13 is performed by pressing a switch on an operation panel (not shown) on the front surface of the casing 1. It should be noted that the arm 11 may be provided with a damper function by a spring or the like so that the insulating core wire a ′ is not abruptly cut into the wire brush 2.

Further, a hood 8 is provided on the front surface of the casing 1 above the insertion port 3, and the hood 8 has two curved plates 8a and 8b as side plates 8c as shown in FIG. It is integrated, and the tip edge gap 8d of both curved plates 8a and 8b is open.

A drawer-type stripping waste container box 4 is provided at the bottom of the casing 1, and most of the stripped off scraps of the insulator fall into the box 4. Check the amount of waste accumulated in the box 4 by looking through the window 1a.

A dust collector 7 is provided on the upper rear surface of the casing 1, and an intake port 7 a of the dust collector 7 is opened to the hood 8. Therefore, when the dust collector 7 is driven and air is sucked in through the opening of the hood 8, an air curtain is formed by the intake air flow in front of the insertion port 3, and this air curtain causes dust dust flowing out from the insertion port 3 to the operator. The dust that has reached the air curtain is smoothly guided to the dust collector 7 through the hood 8.

A universal caster 5 is attached to the bottom surface of the casing 1, and the caster 5 allows the device A to move freely in the front, rear, left and right directions. The movement of the brush 2 in the lengthwise direction with respect to the inserted insulation core line a ′ is performed by moving the device A or by moving the support frame of the brush 2 in the lengthwise direction as described above. To do.

In the embodiment shown in FIG. 2, similarly to the one described in Japanese Patent Publication No. 56-24444, a plurality of columnar rotary brushes 2 are arranged in parallel, and one of the columns is movable up and down. As shown by the solid line in the figure, with both brush rows open, insert the insulating core wire a'and then close it as shown by the chain line in the figure to peel off the insulator. In the figure, M is a brush rotating motor.

In the embodiment shown in FIG. 3, similar to the one described in Japanese Patent Publication No. 56-24445, a wire brush belt 6 as a rotating brush is arranged in parallel, and an insulating core wire is provided between the belts 6. Insert a'and strip the insulator.

As shown in FIG. 5, the device A of each embodiment configured as described above first moves the device itself through the free caster 5 to insulate the insulation core of the cable end a drawn from the drum D. Insert the line a ′ through the insertion port 3. In this state, the rotating brushes 2 and 6 are rotated to remove the insulator of the insulating core wire a '. At this time, most of the stripped insulator scraps fall into the box 4, while the dust that has flown out of the insertion port 3 is further removed by the air curtain below the opening of the hood 8. While being prevented from flowing out, the dust is guided to the inside of the hood 8.

The dust collector 7 may be a paper pack type, which is well known in household vacuum cleaners, and a wiper may be attached to the window 1a. Further, if the air gun is connected to the compressor C, the insulating core wire a'is pulled out from the insertion port 3, and the wire brush 2 can be cleaned by the air gun, deterioration of the stripping action can be reduced.
