BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention,
Although various technically preferable limitations are given, the scope of the present invention is not limited to these forms unless otherwise specified in the description below.

FIG. 1 shows a preferred embodiment of the stripping device for a wire coating material of the present invention. The stripping device 10 for coating a wire material is roughly composed of a base 12 and a driving rotor 1.
4, the driven rotary body 16, the rotation drive unit 18, the slide drive unit 20, and the break forming unit 24. Base 1
Reference numeral 2 is a frame body made of metal, and has a mounting base 26 on the upper portion. The base 12 has a relatively long dimension in the X1 and X2 directions and a relatively short dimension in the Y direction. The rotary drive unit 18 is mounted on the mounting table 26.
The cut line forming portion 24 is fixed.

The driving rotor 14 is, for example, a drive pulley, and the driving rotor 14 has, for example, a V-shaped guide groove 14A over the entire circumference, as shown in FIG. 2 (A). The degauss coil 200 can be hooked on the guide groove 14A. The driving rotor 14 is attached to the output shaft 18A of the rotary drive unit 18. The disk-shaped main rotor 14 is adapted to continuously rotate in the R direction integrally with the drive shaft 18A. The rotary drive unit 18 has a motor 30 and a gearbox 32 for speed reduction. The rotation of the output shaft of the motor 30 is decelerated by the gear box 32 and transmitted to the output shaft 18A. As a result, the rotational speed of the driving rotor 14 is, for example, 60 rpm, which is low and can be rotated with high torque. Although the main rotating body 14 and the driven rotating body 16 have the same outer diameter dimension,
It is made of metal such as iron.

The slide drive unit 20 of FIG. 1 has a rodless cylinder 40, a guide shaft 42, and a support body 44. Rodless cylinder 40 and guide shaft 42
Are provided in parallel along the direction of X1 and X2 at intervals. One end 40A of the rodless cylinder 40 and one end 42A of the guide shaft 42 are attached to the inner surface of the attachment plate 48. The other end 40B of the rodless cylinder 40 is attached to the support body 44. The other end 42B of the guide shaft 42 is fixed to the block body 68A of the pressing drive unit through the hole 45 of the support body 44.

The support 44 has a shaft 50, on which the driven rotor 16 is mounted. Driven rotor 1
6 can rotate about an axis 50. As the driven rotating body 16, for example, a driven pulley as shown in FIG. 2B can be adopted. The rodless cylinder 40 has no piston rod, and the force of the piston is taken out of the cylinder tube by a magnet or a metal fitting. Therefore, the size of the device can be reduced by the length of the rod as compared with an ordinary cylinder. The driven rotor 16 has a guide groove 16A as shown in FIG. 2 (B). The degauss coil 200 is applied to the guide groove 16A. By operating the rodless cylinder 40 of the slide drive unit 20,
The driven rotary body 16 together with the support body 44
In contrast, the sliding movement in the X1 direction increases the distance between the main rotor 14 and the slave rotor 16, and is a type of wire rod having a loop-shaped covering material that is hung on the slave rotor 16 and the main rotor 14. A certain degauss coil 200 can be pulled from the state of FIG. 3 to the state shown in FIG. 4 in a substantially elliptical shape (extended state).

The cut forming portion 24 of FIG. 1 has a base portion 60, a rotary blade 64, a motor 66 and a pressing drive portion 68. The pressing drive unit 68 has a cylinder 70 and a support 72, and the support 72 is vertically fixed on the mounting table 26. Cylinder 7 for support 72
0 is attached. The cylinder 70 is, for example, an air cylinder, and when the cylinder 70 operates, the base 60
Is lowered in the Z1 direction along the guide 80, and the rotary blade 64
The degauss coil 20 that is hung on the driving rotor 14.
It has a function of pressing against the covering tape of 0 to form a break. The rotary blade 64, which is also called a disk cutter, is a disk-shaped blade having a thin outer peripheral portion, and reliably cuts the covering tape of the degauss coil 200. The rotary blade 64 is detachably attached to the output shaft of the motor 66. When the motor 66 operates, the rotary blade 64 rotates in the R direction, for example. As a result, the rotary blade 64 rotates in the opposite direction with respect to the degauss coil 200 that rotates and moves in the R direction, forming a cut in the covering tape.

The degauss coil 200 will now be described with reference to FIGS. FIG. 5 shows a typical cross-sectional structure example of the degauss coil 200. The Degauss coil 200 is a wire rod having a covering material, and has a structure in which a wire rod (copper wire bundle portion) 201 is covered with a covering tape 203 as a covering material. The covering tape is a tape having electrical insulation such as a vinyl tape, and is wound spirally around the outer peripheral surface of the wire 201 with an adhesive or an adhesive as shown in FIG.

As shown in FIG. 7, this degauss coil 2
00 is attached to the cathode ray tube 230. Degauss coils of different sizes are selected and used according to the size of the cathode ray tube. The cathode ray tube 230 is used, for example, as a television receiver or a monitor device of a computer, but in order to prevent the scan control member made of an iron-based material in the cathode ray tube 230 from being magnetized by the earth's magnetism to shift the convergence. For the purpose of degaussing the scanning control member, the degauss coil 200 is installed in the cathode ray tube 23.
It is held by the holding member 240 with respect to the back surface of 0. The motors 30, 66, the rodless cylinder 40,
Then, the cylinder 70 operates according to a command from the control unit 100.

Next, the stripping device 10 for the wire coating material of FIG.
A description will be given of a peeling method in which the covering tape of the Degauss coil 200 is cut and peeled by using. In FIG. 1, the driven rotor 16 is initially located near the main rotor 14. That is, the slide drive unit 20 positions the driven rotary body 16 at the extreme end in the X2 direction.

As shown in FIG. 3, a loop-shaped degauss coil 200 is fitted in the guide groove 14A of the main driving rotor 14 and the guide groove 16A of the driven rotary member 16. Then, the controller 100 operates the rodless cylinder 40 to slide the driven rotor 16 in the X1 direction as shown in FIG. As a result, the main rotor 14 and the driven rotor 16
Widen the space between. Therefore, the degauss coil 200 that has been bent in FIG. 3 is held by the main driving rotor 14 and the driven rotary member 16 in a substantially elliptical shape.

Next, the control unit 100 shown in FIG. 4 operates the motor 30 so that the driving rotor 14 starts rotating at a predetermined rotation speed in the R direction. As a result, the degauss coil 200 is rotated in the R direction into a substantially elliptical shape.
By thus rotating the degauss coil 200 in a pulled state, the bending of the degauss coil removed from the cathode ray tube is corrected, and the copper wire and the covering tape are easily separated.

In FIG. 8, the control unit 100 controls the motor 66.
And the control unit 100 operates the cylinder 70 to lower the rotary blade 64 together with the base 60 onto the driving rotor 14 along the Z1 direction. As a result, the rotary blade 64 is lowered in the Z1 direction while rotating, and as shown in FIGS. 8 and 9, the rotary blade 64 is placed on the cylinder 70 with respect to the covering tape 203 of the degauss coil 200 on the driving rotor 14.
The cut 205 can be reliably and easily formed in the pressed state. In this case, since the degauss coil 200 is continuously rotating in the R direction,
The cut 205 is formed along the longitudinal direction of the degauss coil 200 and extends along the entire length of the degauss coil.

As shown in FIG. 10, the cut 2
After the formation of 05, the control unit 100 operates the cylinder 70 to raise the base 60 and the rotary blade 64 in the Z2 direction, and then the control unit 100 stops the operation of the motor 66. The control unit 100 stops the operation of the motor 30 and stops the rotation of the driving rotor 14. Control unit 100
Operates the rodless cylinder 40 to drive the driven rotor 1
6 is moved to the driving rotor 14 side, that is, in the X2 direction to return to the initial position. As a result, the driving rotor 14
The distance between the driven rotor 16 and the driven rotor 16 is narrowed, and the degauss coil 20
0 changes from a tensioned state to a loosened state. Therefore, the operator can easily remove the degauss coil 200 from the main rotor 14 and the driven rotor 16. As shown in FIG. 11, the detached degauss coil 200 separates the covering tape 203 and the wire 201 by manual work, for example.

FIG. 12 and FIG. 13 show another embodiment of the stripping apparatus for the wire coating material of the present invention. The wire rod coating stripping device 10 of FIG. 12 is different from the wire rod coating stripping device 10 of FIG. 11 in the following points, and the other elements are the same, so the same reference numerals are used for the description. I will use it. In the embodiment shown in FIGS. 12 and 13, the rotary blade 164 of the cut forming portion 24 does not rotate by the motor but rotates together with the rotation of the driving rotor 14. That is, as shown in FIG. 13, the degauss coil 2 guided in the groove 14 </ b> A of the driving rotor 14 is shown.
00, the rotary blade 164 is pressed by the cylinder 70.
The gap 205 can be continuously pressed by being pressed against. As shown in FIG. 13, the rotary blade 16
4 can be rotated together with the base 160 by a shaft 161. By adopting such a structure, one motor can be omitted and the structure of the peeling device can be simplified.

The wire rod coating stripping apparatus 10 shown in FIGS. 14 and 15 differs from the embodiment shown in FIG.
Instead of 64, a blade 260 of another form is used. The blade 260 is provided with a member 261 with respect to the base 160.
It is fixed detachably using. The blade 260 has a sharp tip, and the degauss coil 200 is used as the driving rotor 14.
The slit 205 can be continuously formed along the longitudinal direction of the covering tape 203 by being guided by the guide groove 14A and rotating. Even in this case, the motor can be omitted and the structure of the peeling device can be simplified.

Also in the embodiment shown in FIGS. 1, 12 and 14, the rotary blades 64, 164 and the blade 260 are covered with the covering tape 20 by the force of the cylinder 70 of the pressing drive unit 68.
By being pressed against 3, the covering tape 20
The cut 205 on the 3 is reliable and easy.
00 can be continuously formed along the longitudinal direction.

In the stripping device for stripping wire coating material according to the embodiment of the present invention, the stripping material can be stripped without cutting the loop-shaped degauss coil 200 in the loop shape. Even if the deformed Degauss coil has a twisting deformation because it is removed from the cathode ray tube, by mounting it on the two rotating bodies and then opening the space between the two rotating bodies,
The deformed portion of the Degauss coil can be stretched into an elliptical shape to facilitate cutting of the covering material. By rotating the rotating body while operating in the direction to open the gap between the two rotating bodies, the degauss coil is sent in an elliptical shape and closely adhered to the rotating body so that the degauss coil is twisted and deformed. Facilitates separation from lines. A disk cutter (rotary blade) that reverses the rotation direction of the rotor is installed on the outer periphery of the rotor, and by pressing the rotor blade against the degauss coil, the outer edge of the degauss coil when mounted on the rotor , You can make a cut surely and easily. As a result, a cut is made on the outer side of the covering material of the degauss coil, and the covering material and the copper wire bundle can be separated reliably and easily. The rotary blade may be rotated by power, may not be rotated, or may be freely rotated. Since the rotary blade is pressed against the covering material of the degauss coil, even if the wire diameter is different or the wire diameter is partially different even with the same degauss coil, it is possible to surely and easily form a cut in the covering material.

In the embodiment of the present invention, since the coating material can be peeled off without cutting the loop-shaped Degauss coil, the separation workability is good. Even with a degauss coil having an irregular shape, after the shape is corrected to an elliptical shape, there is no uncut residue due to the mechanism of making a cut in the covering material. In order to rotate the Degauss coil into an elliptical shape by using the main rotating body and the driven rotating body, a bending force is applied to the entire circumference of the coil at the contact points of the circle and the straight line. This action facilitates the separation of the copper wire and the covering material. By peeling off the coating material of the Degauss coil, the copper can be recycled as a simple substance and the value as a valuable resource can be increased. Degauss coils are sometimes burned as a method of separating the coated vinyl tape to recover copper. With this method, vinyl chloride, which is the material for the vinyl tape, is incinerated, so it is necessary to worry about the generation of dioxins. However, in the present invention, the vinyl tape (covering material) itself can be properly disposed of by mechanically separating the covering material from the copper wire.

The present invention is not limited to the above embodiment. In the above-described embodiment, the cylinder 70 is used as the pressing drive unit 68, but the present invention is not limited to this, and a feed mechanism using a feed screw, a nut, and a motor may be used. A cylinder having a rod may be used instead of the rodless cylinder 40. The driving rotor 14 and the driven rotor 16 are disc-shaped or disk-shaped rotors, but the moving direction of the driven rotor 16 is not limited to the horizontal direction as shown in FIG. Of course, it does not matter even if it is vertical.

[0034]

As described above, according to the present invention,
The covering material can be easily and surely peeled off from the wire material such as the Degauss coil.
