Abstract

PROBLEM TO BE SOLVED: To provide a peeling device which does not require adjusting work adjusted to the diameter of a wire rod, in spite of its being inexpensive. SOLUTION: On the basis of centrifugal force, which acts on an arm 102 by rotation of a body 101, face portions 102c move towards a wire rod W is interposed and held by the face portions 102c. Since a covering material for covering the wire rod W is stripped off by being interposed and held by the face portions 102c which rotate and move, an expensive peeling portion by the use of diamond blades as by conventional technique becomes unnecessary, and adjustment to be performed being adjusted to the diameter of the wire rod W becomes unnecessary also. Accordingly, stripping and removal of the covering material to be performed, without taking much labor at a lower cost becomes feasible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stripping device for stripping a coating of a wire for winding, for example, in a winding machine.

[0002]

2. Description of the Related Art Winding machines for manufacturing coils and the like are known. First, a conventional winding machine will be briefly described. FIG. 3 is a perspective view showing an example of a conventional winding machine. In FIG. 3, a wire W is supplied from a wire supply source (not shown) toward the winding machine in the direction of the arrow.

[0003] The supplied wire W is first sent to the lower part of the winding machine through the tension device 10, passes through a thin pipe-shaped nozzle 20 supported by a driving unit 40, and then sandwiches the tip thereof into a holding unit 30. And is held between them.

The nozzle 20 is driven by a driving unit 40 to
It is dimensionally movable, and more specifically, its position can be freely changed above the bobbin B held at the tip of the rotating shaft 50, and its posture can also be changed.

The operation of the winding machine will be described. First, the nozzle 20 is wound around the terminal B1 of the bobbin B while the tip of the wire W is sandwiched by the sandwiching portion 30, and the wire W is wound around the terminal B1. An operation (beard operation) is performed.

When the wire W is entangled with the terminal portion B1, the holding portion 30 moves in a direction away from the bobbin B and cuts the tip of the wire W. When it is difficult to cut the wire W due to the movement of the wire W, the wire W is cut by a nipper supported by the driving unit 40 (not shown). Thereafter, the rotating shaft 50 is rotated at high speed together with the bobbin B. At this time, in synchronism with the rotation of the bobbin B, the nozzle 20 is moved at a predetermined pitch in the longitudinal direction of the bobbin B, thereby preventing the wire from winding around the same location.

When the wire W is wound around the bobbin B a predetermined number of times, the rotating shaft 50 is stopped. After that, the wire W is entangled with the terminal portion B2 of the bobbin B and the wire W is cut again by the unwinding operation of the nozzle 20, and the operation of the winding machine ends.

The wire W is coated with an insulating material such as urethane or polyester so as to electrically insulate the wound portions when the wire W is wound on the bobbin. I have. However, as described above, since the terminal portion B1 is a portion to be electrically connected to the wire W, an insulating material is not required. here,
In the case of the wire W coated with urethane, since the urethane coating of the wire W wrapped around the terminal material B1 is easily melted by soldering to the terminal portion B1, an additional step of peeling the coating material is performed. Even without this, the electrical connection between the wire W and the terminal portion B1 is achieved.

However, for coils used in an environment with severe thermal conditions, such as an engine room of an automobile, a coil made of polyester is often used, but polyester is relatively resistant to heat. And soldering to the terminal part B1,
In many cases, the polyester coating of the wrapped wire W is not completely melted, so that an additional step of peeling the coating material is required before the wrapping operation.

[0010]

In order to solve such a problem, in the prior art, a peeling device is provided in a winding machine to peel off a part of the coating of a wire and wind the peeled portion around a terminal portion. I have. FIG. 4 is a partial sectional view of such a conventional peeling apparatus. Such a peeling device 70
For example, as shown in FIG.
And the nozzle 20.

In FIG. 4, a motor 6 is mounted on a support base 60.
1, an idle shaft 62, and a peeling device 70 are attached. A rotating shaft 61a extends downward from the inverted motor 61, and a pulley 63 attached to the rotating shaft 61a and a pulley 64 attached to an idle shaft 62 rotatably supported on the support base 60. Are connected via a belt 65.

On the other hand, a pulley 66 attached to the idle shaft 62 and a pulley 72 attached to the hollow shaft 71 of the peeling device 70 are connected via a belt 67. The pulley 63, the pulley 64, and the belt 65, and the pulley 66, the pulley 72, and the belt 67 constitute a speed increasing device 68. Inside the hollow shaft 71, an elongated hollow tube 73 is provided.
Are supported via two support members 74a and 74b, and the wire W is inserted through the tube 73.

A peeling section 75 is mounted below the hollow shaft 71. The peeling portion 75 includes a central portion 75a surrounding the tube 73, and 3 provided near the lower end of the central portion 75a.
Each of the supporting portions 75b, a rotating portion 75c rotatably attached to each of the supporting portions 75b, and a diamond blade 75d protruding radially inward near the lower end of each rotating portion 75c. are doing. Note that a dust collecting device 69 is provided adjacent to the peeling portion 75 to suck the peeled coating material to prevent the coating material from re-adhering.

The operation of the peeling device 70 according to the prior art will be described. When the terminal winding portion of the wire W reaches a position facing the diamond blade 75d, the motor 61 drives the rotating shaft 61a to rotate, thereby increasing the speed. The hollow shaft 71 and the peeling unit 75 rotate at the rotation speed increased by the device 68.

When the peeling section 75 rotates, the rotating section 75c rotates according to the centrifugal force, so that the diamond blade 75d protrudes inward. Accordingly, the outer circumference of the wire W is 3
Since the two diamond blades 75d rotate in contact with each other, if the peeling device 70 is moved upward as it is, the coating material is peeled and removed by the diamond blade 75d.

However, the peeling device according to the prior art includes:
There are problems as described below. Since the coating material of the wire W is extremely thin, if the protrusion amount of the diamond blade 75d is large, the core of the wire material W will be scratched, and if the protrusion amount of the diamond blade 75d is small, the coating material will remain. It is necessary to appropriately set the amount of protrusion of the rotation part 75, but such setting is performed by adjusting the rotation angle of the rotation part 75c. However, such adjustment must be performed manually and by trial and error, and each time the diameter of the wire W differs, the adjustment must be performed again, which is troublesome.

In addition, the peeling section 75 provided with the diamond blade 75d is very expensive, and some pieces cost more than 300,000 yen. Therefore, a lower cost peeling apparatus is desired.

On the other hand, a wire called a flat wire is a wire whose cross section is thin with respect to its width and can generate a strong magnetic force when wound in a coil shape. . However, since the cross section of the rectangular wire is not circular, the conventional peeling device cannot be used as it is, and there is a problem how to peel off the coating material coated on the outer periphery.

The present invention has been made in view of such a conventional problem, and has a peeling device which is inexpensive but does not require an adjusting operation according to the diameter of a wire, and has a special sectional shape. An object of the present invention is to provide a peeling device that can handle a wire.

[0020]

In order to achieve the above-mentioned object, a first peeling device has a frictional heat generating means for generating a frictional heat by a coating material engaging with a wire covered on an outer periphery. ,
The coating material coated on the wire is peeled off based on heat generated by the frictional heat generating means.

The second peeling device of the present invention has an engaging means for engaging a wire covered with a coating material on an outer periphery, and the coating material coated on the wire is provided with an engaging means for engaging the engaging means. It is characterized by being peeled off by wear based on

The third peeling device of the present invention is arranged such that at least one of the pair of opposing surfaces is movable toward the wire whose outer periphery is covered with the coating material, and the adjusting device is connected to the movable opposing surfaces. Part, the facing surface part and the adjusting part,
A rotating unit that rotates around the wire, and the movable opposing surface unit moves toward the wire based on centrifugal force acting on the adjusting unit by rotation of the rotating unit, With a pressing force, the pair of opposed surface portions sandwich the wire, and the coating material coated on the wire is peeled off by being sandwiched by the rotating facing surface portion. I do.

The fourth peeling device of the present invention is a peeling device for peeling a coating material covering the outer periphery of a wire whose cross section in a direction perpendicular to the longitudinal direction is thinner than the width. A pair of rollers for sandwiching the wire in the thickness direction of the wire, first driving means for rotating the roller, and second driving means for moving the roller along the wire. And, while pinching the wire with the rollers,
The roller is rotated by the first driving means,
Further, the second driving means moves the roller to remove the covering material from the outer periphery of the wire.

[0024]

According to the first stripping device of the present invention, the coating material has frictional heat generating means for generating frictional heat by engaging the wire with the outer peripheral coating, and the coating material coated on the wire. Is peeled off based on the heat generated by the frictional heat generating means, so that an expensive peeling section using a diamond blade as in the prior art is unnecessary, and an inexpensive peeling device is provided.

According to the second peeling device of the present invention, there is provided the engaging means for engaging the wire covered with the covering material on the outer periphery, and the covering material covered by the wire is provided by the engaging means. Since the exfoliation is caused by the abrasion due to the engagement, an expensive exfoliation section using a diamond blade as in the prior art is not required, and an inexpensive exfoliation apparatus is provided.

According to the third stripping apparatus of the present invention, at least one of the pair of opposing surfaces is movable toward the wire whose outer periphery is covered with the coating material, and the pair of opposing surfaces is connected to the movable opposing surface. Adjusting part, and a rotating part that rotates the facing surface part and the adjusting part around the wire rod,
Based on the centrifugal force acting on the adjusting unit due to the rotation of the rotating unit, the movable opposing surface portion moves toward the wire, and with a predetermined pressing force, the pair of opposing surface portions sandwich the wire. As the coating material coated on the wire is peeled by being sandwiched by the facing surface portion that rotates, an expensive peeling portion using a diamond blade as in the related art is unnecessary, In addition, since there is no need for adjustment according to the diameter of the wire, the coating material can be peeled and removed at a lower cost without any trouble.

If a change means for changing the rotation speed of the rotating portion is provided, the centrifugal force increases and decreases according to the rotation speed, so that the pressing force of the facing surface portion can be adjusted.

Further, if a change means for changing the mass of the adjusting portion is provided, the centrifugal force acting on the adjusting portion can be changed even when the rotating portion has a constant rotation speed, so that the pressing force of the facing surface portion can be reduced. Can be adjusted.

Further, if a rotatable arm for connecting the facing surface portion and the adjusting portion is provided, and changing means for changing the distance between the turning point of the arm and the position of the center of gravity of the arm is provided, Since the centrifugal force acting on the adjusting portion can be changed even when the rotating portion has a constant rotation speed, the pressing force of the facing surface portion can be adjusted.

Further, the opposing surface portion and the adjusting portion are connected by a pair of arms, and the arm is rotatable along a surface substantially orthogonal to a direction in which the wire extends. If it is, the length of the peeling device can be suppressed compactly in the direction in which the wire extends.

Also, two sets of the opposing surface portion and the adjusting portion facing each other are provided side by side in the extending direction of the wire, and the rotating portion is provided with each pair of the opposing surface portion and the adjusting portion. If the portions are rotated in opposite directions, the twist applied to the wire can be suppressed by canceling the force applied to the outer periphery of the wire.

Further, if the holding surface of the opposing surface portion for holding the wire moves substantially in parallel when approaching the wire, it can be brought into parallel contact with the outer peripheral surface of the wire regardless of the thickness of the wire, for example. Thus, the coating material can be stably peeled off.

According to the fourth peeling apparatus of the present invention, a peeling apparatus for peeling a coating material coated on an outer periphery of a wire whose cross section in a direction perpendicular to the longitudinal direction has a thickness smaller than a width is provided. A pair of rollers for sandwiching the wire in a thickness direction of the wire, first driving means for rotating the roller, and a second driving means for moving the roller along the wire.
And the first driving means rotates the roller while holding the wire with the roller, and further moves the roller by the second driving means to move the wire. Since the covering material is removed from the outer periphery, the covering material can be effectively removed even if the cross-sectional shape is not circular.

By providing a sensor for detecting that the coating material has been peeled off from the wire, it is possible to detect whether or not the coating material has been properly peeled off from the wire. This is convenient because measures such as stopping the rotation of the rotating unit can be performed.

[0035]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a peeling device according to a first embodiment of the present invention, and FIG.
FIG. 2 is a view of the peeling device of FIG. 1 cut along a line II-II and viewed in a direction indicated by an arrow.

1 and 2, the peeling apparatus 100 has a cylindrical main body 101 and a pair of arms 102 rotatably arranged on both sides of the main body 101. Body 10
Reference numeral 1 denotes a supporting member 11 whose upper end is indicated by a dashed line in FIG.
0 is supported. On the outer periphery of the support member 110, for example, a pulley 111 that is engaged with the belt 67 of the speed increasing device 68 shown in FIG. That is, the main body 101 is rotatable by a motor (not shown) in FIG. Note that the peeling device 100 shown in FIGS. 1 and 2 may have compatibility so that it can be attached to the hollow shaft 71 instead of the peeling portion 75 in FIG.

In the upper part of the through hole 101a of the main body 101,
A ceramic tube 103 for protecting the coating of the wire W from being in contact with the main body 101 is fitted therein, and the wire W passes therethrough. Body 101
A flange portion 101b is formed on the outer periphery at the center of the pair, and the flange portion 101b is further cut inward on both sides shown in FIG.
c is formed. Also, on both lower sides of the main body 101,
A pair of support portions 101d each protruding in opposition are formed.

An opening 101e (FIG. 1) is formed in the support portion 101d, and a pin 104 is implanted in the opening 101e.

On the other hand, a pair of arms 102 extending along both sides of the main body 101 have a circular hole 102a formed at the center, and a pin 104 is inserted through the circular hole 102a. That is, each arm 102 is rotatably supported by the support portion 101d via the pin 104.

Each arm 102 has a shape in which a portion (upper portion) above the circular hole 102a is thick, that is, has a larger mass. The upper end of each arm 102 is
By being locked to b, further rotation is restricted.

A short prism is provided at the lower end of each arm 102 in FIG.
Opposing portion 102b shaped to extend perpendicular to the plane of the paper
Are formed. The pair of arms 102 are closed (FIG. 2)
), The opposite portion 1
02b opposing surface portions 102c sandwich the wire W. The roughness of the surface portion 102c can be variously adjusted according to the type of the covering material of the wire W. Since the lower ends of the arms 102 are urged by the springs 108, when the centrifugal force is not generated in the arms 102, the pair of arms 102 is opened (shown by a solid line in FIG. 2). Will be maintained.

At the upper end of each arm 102, a screw hole (not shown) is formed.
Is screwed. The bolt 105 is locked by a lock nut 106 at an arbitrary position.
The upper part of the arm 102 including the bolt 105 constitutes an adjusting unit.

Below the peeling device 100, a color sensor 107 capable of detecting the color of the wire W is disposed so as to face the wire W.

Next, the operation of the peeling apparatus 100 will be described. In the winding machine shown in FIG. 3, when peeling of the coating material is not necessary, such as the portion of the wire wound around the winding portion of the bobbin, the peeling device 100 does not operate, that is, the solid line shown in FIG. Maintain arm 102 in position.

On the other hand, when the wire W is fed out by the nozzle to a position corresponding to the portion which is wrapped around the terminal portion of the bobbin, a motor (not shown) rotates and the peeling device 10
0 body 101 is rotated. At this time, a centrifugal force is generated in each arm 102 that rotates together with the main body 101. However, as described above, since the upper portion has a larger mass,
Are pivoted in the direction in which the lower ends of the pair of arms 102 are closed, and the surface portion 102c is pressed by a predetermined pressing force based on the centrifugal force.
Hold the wire W.

Since the arm 102 rotates together with the main body 101, when the surface portion 102c is pressed against the wire W, frictional heat is generated, whereby the coating material of the wire W is melted or hardened, and furthermore, the mechanical rotating power is generated. (That is, frictional force)
By being applied from 02c, peeling and removal are performed. That is, the surface portion 102c constitutes frictional heat generation means and engagement means. Even when such a covering material is, for example, a heat-resistant polyester, for example, by increasing the number of rotations of the motor or projecting the bolt 105 further upward in a known manner, the arm 102 with respect to the pin 104 as the pivot point is If the centrifugal force is increased by changing the position of the center of gravity, the frictional heat can be increased, and the coating material can be easily peeled off. In addition, the centrifugal force can be reduced by reducing the rotation speed of the motor in a known manner or by screwing the bolt 105 further downward, so that the frictional heat can be reduced. Peeling is possible.

By moving the peeling device 100 upward over a predetermined distance while holding the wire W between the surface portions 102c, the coating material at the portion of the bobbin that is wrapped around the terminal portion is removed. At this time, if the covering material is not sufficiently removed from the periphery of the wire W, the color sensor 107 detects that a darker covering material is attached to the material of the wire W, for example. Can be sent. In response to such a signal, in addition to the action of stopping the operation of the peeling apparatus and outputting an error message, the peeling step is performed again by providing feedback control such as increasing the rotational speed of the motor to increase the frictional force. It is also possible to make it.

As described above, according to the present embodiment, an expensive exfoliated portion using a diamond blade as in the prior art is not required, and adjustment according to the diameter of the wire W is not required. Therefore, the coating material can be peeled and removed at a lower cost.

FIG. 5 is a side view of a peeling apparatus 200 according to a second embodiment of the present invention, and FIG. 6 is a top view thereof. In FIG. 5, a hollow rotary shaft 20 rotatably supported by a bearing 202 with respect to a base 201 is shown.
No. 3 has a rotating part 210 provided at its upper end and a pulley 204 attached to its lower end.

The pulley 204 is driven by a motor (not shown) via a V-belt 205, and rotates a rotating unit 210 via a rotating shaft 203. The wire W extends from the upper part to the lower part in the center of the rotating part 210, the rotating shaft 203 and the pulley 204.

In FIG. 6, a rotating part 210 which may be integral with or separate from the rotating shaft 203 has a flange (bottom) only on the lower side.
And a bottom surface 2 of the rotating part 210.
A cylindrical ceramic eyelet 204 serving as a guide for the wire W is disposed at the center of 10a, and a pair of cylindrical pins 211 are implanted on the bottom surface 210a at equal intervals from the center. The center of a substantially rectangular arm 212 as viewed from above is fitted to each pin 211, and the arm 212 is rotatable around the pin 211.

Each of the arms 212 is moved by a winding spring 213 wound around a pin 211 to the inward end 212a of the arm.
They are urged in a direction in which they are separated from each other. Inner tip 21
A chip 214 made of a material having excellent abrasion resistance such as a ceramic or a material having a rough surface such as a file is attached to the facing surface 2a according to the type of the wire. On the other hand, a bolt 215 as an adjusting portion is screwed to the outer end 212b of each arm 212.

Next, the operation of the peeling apparatus 200 will be described. FIG. 7 is a perspective view showing the operation of the arm 212. First, in the winding machine shown in FIG. 3, when peeling of the covering material is not necessary, such as a wire portion wound around a winding portion of a bobbin, the peeling device 200 does not operate,
That is, since the rotating unit 210 is in a stationary state,
The arm 212 is maintained at the position shown in FIG.

On the other hand, when the wire W is fed out by the nozzle to a position corresponding to the portion of the V-belt which is wound on the terminal portion of the bobbin, the motor (not shown) rotates and the V-belt 20 is rotated.
5, rotating section 210 via pulley 204 and rotating shaft 203
To rotate. At this time, a centrifugal force is generated on the outer end 212b side of each arm 212 that rotates together with the rotating part 210 in the direction indicated by arrow A in FIG.
(Not shown), the pair of arms 212 rotate about the pin 211 in a direction to bring the inner ends 212a closer to each other. By this rotation, the tip 214 holds the wire W with a predetermined pressing force based on the centrifugal force.

Since the arm 212 rotates together with the rotating portion 210, when the tip 214 is pressed against the wire W, frictional heat is generated, whereby the coating material of the wire W is melted or hardened, and further, the mechanical rotation is performed. When power (that is, frictional force) is applied from the chip 214, separation and removal are performed. That is, the tip 214 constitutes frictional heat generation means and engagement means.

If the rotation speed of the motor is increased, the efficiency of removing the coating material is increased. However, the material of the chip 214 is changed according to the type of the coating material, and is relatively low by using a material such as a file, for example. The coating material can be easily peeled even at a rotation speed. Further, similarly to the above-described embodiment, the centrifugal force acting on the arm 212 can be changed by changing the screwing amount of the bolt 215, so that it can be adjusted according to the type of the covering material.

By moving the peeling device 200 upward over a predetermined distance while the wire W is held between the chips 214, the covering material of the portion to be wrapped around the terminal portion of the bobbin is removed. At this time, when the covering material is not sufficiently removed from the periphery of the wire W, it is determined that, for example, a darker covering material is attached to the material of the wire W as in the above-described embodiment. , A color sensor (not shown) can detect and transmit a signal.

According to the present embodiment, as in the above-described embodiment, a cutting tool such as a cutting tool is not used, so that the processing of the facets, which has been a problem in the conventional peeling apparatus, is facilitated. Further, the arm 212 is connected to the bottom surface 21 of the rotating unit 210.
0a, that is, rotatable along a plane substantially perpendicular to the direction in which the wire W extends, the peeling device 20
The dimension of 0 can be suppressed compactly in the direction (vertical direction) in which the wire W extends. The peeling device 200
Since the portion to be wrapped around the terminal portion of the bobbin is predicted in advance and the covering material is removed, the prediction becomes more accurate as the wire W is closer to the bobbin. Therefore, if the length of the peeling device 200 can be made compact in the direction in which the wire W extends (vertical direction) as in the present embodiment, the peeled portion of the wire W can be more accurately wrapped around the terminal portion. Can be

Further, according to the present embodiment, the inner end 212a of the arm 212, which is the opposing surface for holding the wire W,
Since the (tip 214) moves substantially in parallel when approaching the wire W, it can be brought into parallel contact with the outer peripheral surface of the wire W regardless of the thickness of the wire W, for example. The coating material can be stably peeled off. Also,
Adjustment of the pressing force of the arm 212 is also easy.

FIG. 8 is a side view of a peeling device 200 'according to a modification of the present embodiment. In such a modification, the peeling devices 200 of FIGS. 5 to 7 are arranged in series along the wire W so that the rotating parts 210 face each other. Two sets of the combination of the opposing surface portion and the adjusting portion are provided side by side in the extending direction of the wire. The V-belt 205 of the upper peeling device 200 is connected to the upper bevel gear 221 via a pulley not shown in FIG.
The V belt 205 of the lower peeling device 200 is connected to the lower bevel gear 222 via a pulley not shown in FIG. Another bevel gear 223 meshes with both bevel gears 221 and 222 on the right side. The lower bevel gear 222 is driven to rotate by a motor 210.

The peeling operation of the peeling device 200 ′
Although the description is omitted because it is the same as the above-described embodiment, according to this modification, bevel gears 221, 222, 223
Thus, rotation in one direction of the motor 220 is transmitted to the lower rotating unit 210 in the same direction and to the upper rotating unit 210 in the opposite direction. Therefore, since the arm arranged on the upper rotating part 210 and the arm arranged on the lower rotating part 210 rotate in opposite directions, respectively,
When these are in contact with the outer periphery of the wire W, the torsional force applied to the wire W can be offset, so that the twist of the wire W can be suppressed, and is suitable, for example, for removing a thin wire that is vulnerable to twisting. It is.

FIG. 9 is a perspective view of a peeling device 300 according to the third embodiment. A wire called a flat wire is a wire whose cross section is thin with respect to its width and does not have a circular cross section, so that a conventional peeling device cannot be used as it is. According to the peeling device 300 described below, the covering material of the flat wire can be effectively peeled.

In FIG. 9, second driving means (not shown)
The first arm 302 is arranged so as to be fixed to the base 301 which is configured to be movable along the rectangular wire WF. The distal end of the first arm 302 has a built-in motor 303 as first driving means, and its rotation shaft (not shown) is connected to a roller 304 coaxial with the motor. At an end of the roller 304, a driving roller 304a that rotates integrally is provided.

A roller 305 is disposed above the roller 304 with the rectangular wire WF interposed therebetween. A non-drive roller 305a that rotates integrally is provided at an end of the roller 305. The roller 305 is rotatably supported at one end of an arm 306, and the other end of the arm 306 is attached to an upper end of a moving member 307. Moving member 3
07 is pushed upward with respect to the base 301 by the driving force of a driving means (not shown) such as an air cylinder, and when the driving force disappears, it moves downward by the urging force of a spring (not shown). ing. Although the roller 304 is fixed in the present embodiment, the roller 304 may be moved in synchronization with the roller 305, or the roller 304 may be moved while fixing the roller 305.

Next, the operation of the peeling device 300 will be described. First, when it is not necessary to peel the covering material of the flat wire WF, the peeling device 300 moves the moving member 307 to the base 3.
01, the rollers 304,
The wire WF is allowed to pass between 305.

On the other hand, when the coating material of the rectangular wire WF reaches the part where the coating material is to be peeled, the peeling device 300 loses the driving force of the driving means and moves the moving member 307 according to the biasing force of the spring.
Is pressed down, and the wire WF is placed between the rollers 304 and 305.
Sandwich. At this time, the driving roller 304a and the driven roller 305a engage with each other, and the driving roller 304a
a to the driven roller 305a.

In this state, the motor 303 is driven to
When the roller 304 is rotated, the roller 305 rotates in the opposite direction via the driving roller 304a and the driven roller 305a. By driving the motor 303, the rollers 304,
Friction heat is generated between the upper and lower surfaces of the wire 305 and the upper and lower surfaces of the wire WF, whereby the coating material of the wire W is melted or hardened, and further, a mechanical rotating force (that is, a frictional force) is applied to the wire WF, whereby the wire WF is separated. Removal is performed. Here, when the base 301 is moved in the opposite direction to the supply direction along the wire WF by the second driving means, the coating material can be peeled over a predetermined distance. Here, the rollers 304 and 305 constitute frictional heat generating means and engaging means.

As described above, according to the present embodiment, it is possible to peel off the covering material of the flat wire WF, which is difficult with the conventional peeling device. Further, in removing the covering material of the flat wire WF, a cutting tool such as a cutting tool is not used.
No damage to the heartwood. Also, a single peeling device 30
At 0, it is possible to process wires WF of various thicknesses and widths.

Although the present invention has been described with reference to the embodiments, it should be understood that the present invention should not be construed as being limited to the above-described embodiments, and that modifications and improvements can be made as appropriate. is there.
