[0043] [First Implementation Method]

[0044] The following is for reference Figures 1 to 11 The wire forming system 100 of the first embodiment of this disclosure will be described. For example... Figure 1 As shown, the wire forming system 100 includes a wire coating removal device 10 and a wire forming machine 80. After the wire coating removal device 10 removes the coating from the wire 90, the wire forming machine 80 forms it into a wire product 91. An example of the wire 90 is shown in Figure 2(A), and an example of the wire product 91 is shown in Figure 2(B).

[0045] As shown in Figure 2(A), the wire 90 is, for example, a wire body 90A, which is a conductive metal, covered by an insulating coating 90B, and its cross-sectional shape is, for example, a flat rectangle. Furthermore, the metal constituting the wire body 90A is, for example, copper or a copper alloy, and the coating 90B is, for example, enamel.

[0046] It should be noted that the cross-section of the wire 90 in this embodiment is a flat quadrilateral, but it is not limited to this; the cross-sectional shape can also be a polygon other than a quadrilateral, a circle, or an ellipse. Furthermore, the metal constituting the wire body 90A is not limited to copper or copper alloys; it can be any formable component, and can also be a non-conductive component. When the wire coating removal device 10 and the wire forming machine 80 are used alone, the wire body 90A can also be a non-formable component. Additionally, in this embodiment, the coating 90B is, for example, enamel, but it can also be an insulating resin; it can be any material that covers the wire body 90A and is not necessarily insulating. Moreover, the wire body 90A and the coating 90B can be a single layer or a multi-layer structure.

[0047] As shown in Figure 2(B), the wire-formed article 91 of this embodiment is, for example, a coil, and has a structure in which a pair of extension portions 93 extend from the coil body 92. An electrical connection portion 95 exposed on the front end face and four sides of the wire body 90A is provided at the front end of each extension portion 93.

[0048] As shown in Figure 2(C), the wire coating removal device 10 removes a predetermined length of coating 90B from the wire 90 at predetermined intervals L0, representing the unfolded length of the wire forming 91, to form exposed surfaces 94 of the wire body 90A. Each exposed surface 94 consists of a pair of first exposed surfaces 94A located on the upper and lower sides of the wire 90, and a pair of second exposed surfaces 94B located on the lateral sides of the wire 90. Furthermore, the wire forming machine 80 cuts the wire 90 at the center of each exposed surface 94. Thus, the aforementioned electrical connection portion 95 is formed by the exposed surface 94, which is half its length, and the cut surface.

[0049] It should be noted that the wire forming article 91 in this embodiment is a coil, but it can also be U-shaped, V-shaped, or any other shape. Furthermore, the electrical connection portion 95 is only provided at the end of the wire 90 constituting the wire forming article 91, but it is not limited to this and can be disposed at any position. Moreover, the electrical connection portion 95 is not limited to being composed of the exposed surface 94 and the cut surface of the wire 90; for example, it can be composed only of the exposed surface 94. Furthermore, the exposed surface 94 is not limited to being composed of a pair of first exposed surfaces 94A and a pair of second exposed surfaces 94B; for example, it can be composed of only either one of the pair of first exposed surfaces 94A and the pair of second exposed surfaces 94B.

[0050] The structure of the wire coating removal apparatus 10 will now be described. Hereinafter, the wire coating removal apparatus 10 will... Figure 3 The side shown is called the "front side", and its opposite side is called the "rear side". Figure 3The direction orthogonal to the paper surface is called the front-back direction. Additionally, the front-back direction can sometimes be the transverse direction of the wire 90° of the wire supply path R, as described later. It should be noted that in... Figures 4-8 In the diagram, arrow "F" indicates forward and arrow "R" indicates backward.

[0051] like Figure 3 As shown, the wire coating removal apparatus 10 extends horizontally and includes a wire supply path R for supplying wire 90, and a wire supply device 11 is located at one end of the wire supply path R. The wire supply device 11 includes a pair of rollers 12 facing each other in the vertical direction, clamping the wire supply path R, and a servo motor 13 (see reference 10) serving as the rotation drive source for them. Figure 4 Furthermore, the wire 90 is clamped between a pair of rollers 12, and through the symmetrical rotation of the pair of rollers 12, the wire 90 moves along the wire supply path R towards... Figure 3 The wire supply is directed to the right. Hereinafter, the direction in which the wire supply path R extends will be referred to as the "wire supply direction H1".

[0052] A wire guide member 20 is provided upstream of the wire supply device 11 in the wire supply direction H1. The wire guide member 20 has a guide hole 20H extending through the wire supply direction H1. The cross-sectional shape of the guide hole 20H is a flat rectangle in the vertical direction, allowing the wire 90 to pass through precisely (see Figures 6(A) and 6(B)). Furthermore, the guide hole 20H forms part of the wire supply path R, through which the wire 90 is guided towards the wire supply device 11.

[0053] It should be noted that the wire supply device 11 is disposed on the downstream side of the wire supply direction H1 relative to the wire guide member 20, but it can also be disposed on the upstream side of the wire supply direction H1 relative to the wire guide member 20, or it can be disposed in the middle position.

[0054] like Figure 3 as well as Figure 4 As shown, a first disconnection portion 21 and a second disconnection portion 22 are provided at two locations midway along the wire supply direction H1 on the wire guide member 20. Furthermore, as... Figure 3 As shown, a pair of first rotating tools 31 approach and separate from both sides in the vertical direction relative to the wire 90 exposed at the first break 21 on the upstream side, and, as Figure 4 As shown, a pair of second rotating tools 32 approach and separate from the wire 90 exposed at the second break 22 on the downstream side from both lateral sides. Thus, the coating 90B at any location on the wire 90 is removed by the first rotating tool 31 and the second rotating tool 32.

[0055] Specifically, the wire guiding member 20 is generally in the shape of a rod with a quadrilateral cross-section, and as... Figure 5 As shown, it is divided into an upstream guide portion 20A, which is upstream of the first disconnection portion 21; an intermediate guide portion 20B, which is between the first disconnection portion 21 and the second disconnection portion 22; and a downstream guide portion 20C, which is downstream of the second disconnection portion 22. Additionally, as... Figure 3 As shown, the ends of the upstream guide portion 20A and the intermediate guide portion 20B, which are joined at the first disconnection portion 21, are tapered shapes with a pair of bevels above and below the wire supply path R (guide hole 20H), and as... Figure 4 As shown, the ends of the intermediate guide portion 20B and the downstream guide portion 20C, which are connected at the second disconnection portion 22, are tapered with a pair of bevels in front of and behind the wire supply path R (guide hole 20H).

[0056] like Figure 4 As shown, the upstream guide portion 20A, the intermediate guide portion 20B, and the downstream guide portion 20C (collectively referred to as "guide portions 20A, 20B, and 20C") are supported by the support member 23 and arranged in a straight line. Furthermore, the guide unit 20U, which includes the guide portions 20A, 20B, and 20C and the support member 23, is mounted between the support platform 15 and the support wall 14.

[0057] like Figure 5 As shown, the support member 23 is formed, for example, by having a bridge-shaped body 25 at one end of the cylindrical body 24. The bridge-shaped body 25, for example, is constructed by connecting three opposing walls 25A, 25B, and 25C arranged along the wire supply direction H1 using connecting walls 25S. Viewed from the wire supply direction H1, as shown in FIG. 6(A), the opposing walls 25A, 25B, and 25C are, for example, rectangular plates with chamfered corners, and the four sides of the rectangle are inclined at an angle of 45° relative to the vertical direction. Furthermore, fitting holes 25H with quadrilateral cross-sections are formed on the three opposing walls 25A, 25B, and 25C. And, as... Figure 5 As shown, the upstream guide portion 20A is fitted into and fixed to the upstream opposing wall 25A near its downstream end by welding or the like, the middle portion of the intermediate guide portion 20B is fitted into and fixed to the central opposing wall 25B by welding or the like, and the downstream guide portion 20C is fitted into and fixed to the downstream opposing wall 25C near its upstream end by welding or the like.

[0058] In detail, as shown in Figure 6(A), the aforementioned opposing walls 25A, 25B, and 25C, when viewed from the wire supply direction H1, are rectangular in shape, with the longer side slightly longer than the shorter side. One of the shorter sides is located on the upper rear side, while the other's shorter side is located on the lower front side. Furthermore, the top and bottom corners of the rectangle are chamfered to be horizontal, and the rear corner is chamfered to be vertical. Additionally, the connecting wall 25S is a strip extending along the wire supply direction H1, configured such that its width direction is parallel to the upper rear short side of the opposing walls 25A, 25B, and 25C. It is connected to the edges of the upper rear short sides of these opposing walls 25A, 25B, and 25C in a manner that sandwiches between adjacent opposing walls 25A and 25B, and between opposing walls 25B and 25C.

[0059] like Figure 5 As shown, the aforementioned cylindrical body 24 extends from the upstream end of the bridge-shaped body 25 towards the upstream side of the wire supply direction H1. Furthermore, the four sides of the cylindrical body 24 are inclined at an angle of 45° relative to the vertical direction. The cylindrical body 24 is fitted with a clearance fit on the outer side of the middle portion of the upstream guide portion 20A along its length, and the upstream guide portion 20A extends further upstream from the cylindrical body 24. Additionally, a flange (not shown) extending laterally is provided at the upstream end of the cylindrical body 24.

[0060] like Figure 3 As shown, the aforementioned support platform 15 is located upstream of the wire supply device 11 in the wire supply direction H1, and is fixed together with the wire supply device 11 to the upper surface of the support worktable 60. Furthermore, the aforementioned support wall 14 stands vertically from the upper surface of the support worktable 60, and is plate-shaped with principal planes orthogonal to the wire supply direction H1 on both sides. Additionally, a quadrilateral through hole 14H corresponding to the wire guide member 20 is formed in the support wall 14.

[0061] And, as Figure 4 As shown, the portion of the upstream guide 20A protruding from the square tube 24 in the wire feeding direction H1 is fitted into the through hole 14H of the support wall 14, and the flange of the square tube 24 (not shown) overlaps and is bolted to the main plane of the support wall 14. Additionally, as... Figure 3 As shown, the downstream guide portion 20C is fixed to the upper surface of the support platform 15 with its middle portion overlapping in the length direction, and extends to the position in front of a pair of rollers 12 in the wire supply device 11. It should be noted that the downstream end of the downstream guide portion 20C has a pointed shape with a pair of inclined surfaces on the top and bottom, separated by the wire supply path R (guide hole 20H).

[0062] It should be noted that the bridge-shaped body 25 of the support member 23 is rectangular when viewed from the wire supply direction H1, but it can also be circular or any other shape. Similarly, the square tube 24 can also be cylindrical or any other shape. Furthermore, the square tube 24 has an upstream guide portion 20A fitted inside with a clearance, but this is not limited to it; for example, it can be an interlocking mechanism. Additionally, the support structure of the guide portions 20A, 20B, and 20C is not limited to the support member 23 described above. For example, the upstream guide portion 20A and the intermediate guide portion 20B, and the intermediate guide portion 20B and the downstream guide portion 20C, can be connected using strip members to avoid interference with the pair of first rotating tools 31 and the pair of second rotating tools 32 described later.

[0063] A pair of first rotating tools 31 are cylindrical in shape, parallel to the front-rear direction of the wire supply device 11, and are composed of... Figure 7 The pair of first rotary drive mechanisms 41 shown are driven separately. Each first rotary drive mechanism 41 has a motor 43 and a support portion 44 coaxially mounted on the first rotary tool 31. In addition, the pair of first rotary drive mechanisms 41 are arranged separately front and rear across the wire supply path R to avoid interference. Specifically, for the first rotary drive mechanism 41 of the upper first rotary tool 31, the motor 43 and the support portion 44 are arranged in a position further forward than the first rotary tool 31, and for the first rotary drive mechanism 41 of the lower first rotary tool 31, the motor 43 and the support portion 44 are arranged in a position further rear than the first rotary tool 31.

[0064] A pair of second rotary tools 32 are also cylindrical, parallel to the vertical direction, and are driven by a pair of second rotary drive mechanisms 42 with the same structure as the first rotary drive mechanism 41. Furthermore, to avoid interference, the pair of second rotary drive mechanisms 42 are arranged vertically and vertically, separated by the wire supply path R. Specifically, for the second rotary drive mechanism 42 of the front second rotary tool 32, the motor 43 and support 44 are positioned higher than the second rotary tool 32; for the second rotary drive mechanism 42 of the rear second rotary tool 32, the motor 43 and support 44 are positioned lower than the second rotary tool 32.

[0065] A pair of first rotary drive mechanisms 41 and a pair of second rotary drive mechanisms 42 are driven in such a way that a pair of first rotary tools 31 rotate symmetrically with each other and a pair of second rotary tools 32 rotate symmetrically with each other. Furthermore, the first rotary tools 31 and the second rotary tools 32 press the outer peripheral surface onto the wire 90 to remove the coating 90B.

[0066] The first tool spacing changing mechanism that changes the distance between a pair of first rotating tools 31 and the second tool spacing changing mechanism that changes the distance between a pair of second rotating tools 32 share a pair of sliding mechanisms 70, and are configured such that when a pair of first rotating tools 31 are close to each other, a pair of second rotating tools 32 are separated from each other, and when a pair of first rotating tools 31 are separated from each other, a pair of second rotating tools 32 are close to each other.

[0067] Specifically, such as Figure 8 As shown, a pair of sliding mechanisms 70 are symmetrically arranged with the wire supply path R as the center point. Each sliding mechanism 70 has a guide rail 72 and a ball screw 73 extending in a direction inclined forward and upward at an angle of, for example, 45° relative to the vertical and horizontal directions (hereinafter referred to as "specific inclination direction H2") in a plane parallel to the main plane of the support wall 14. To support the guide rail 72 and the ball screw 73, a strip-shaped fixing plate 71 extending along the specific inclination direction H2 is overlapped and fixed to the main plane of the support wall 14 facing the support platform 15. Furthermore, the guide rail 72 is fixed in the fixing plate 71 and on the side of the main plane of the support wall 14 near the wire supply path R. In addition, on the side of the main plane of the fixing plate 71 away from the wire supply path R, a pair of protrusions 71A are provided near one end and the other end of the fixing plate 71 in the specific inclination direction H2, and the two ends of the ball screw 73 are rotatably supported on the pair of protrusions 71A. Furthermore, a motor support protrusion 71B protrudes from the other end of the fixed plate 71. Additionally, at one end of the fixed plate 71 supporting the servo motor 74 with a speed reducer, the rotary output shaft of the servo motor 74 with the speed reducer is connected to the ball screw 73 in a manner that allows it to rotate integrally. Moreover, a sliding base 77 is fixed to the ball nut 75 screwed to the ball screw 73, and to a pair of sliding members 76 that are slidably engaged with the guide rail 72 and located on both sides of the ball nut 75. The sliding base 77 can be moved to any sliding position by the servo motor 74 with the speed reducer.

[0068] Furthermore, in this embodiment, the servo motor 74 with a speed reducer of the sliding mechanism 70 (hereinafter referred to as "the front sliding mechanism 70") located at the upper end of the fixed plate 71, while the servo motor 74 with a speed reducer of the sliding mechanism 70 (hereinafter referred to as "the rear sliding mechanism 70") located at the lower end of the fixed plate 71, is also located at the lower end of the fixed plate 71. Moreover, a through hole 60B for accommodating the lower end of the front sliding mechanism 70 is formed in the top plate 60A of the supporting worktable 60.

[0069] It should be noted that, in this embodiment, the specific tilt direction H2 mentioned above is equivalent to the "third direction" in the technical solution, the up and down direction is equivalent to the "first direction" in the technical solution, and the front and back direction is equivalent to the "second direction" in the technical solution.

[0070] The sliding base 77 is a strip-shaped structure extending along a specific inclined direction H2 and parallel to the fixed plate 71. Furthermore, on the front side of the sliding base 77, a motor 43 of the upper first rotary drive mechanism 41 and a support portion 44 are fixed to its upper end, and a base member 78 (see reference) is connected to the lower end of the sliding base 77. Figure 3 The motor 43 and support 44 of the second rotary drive mechanism 42 on the rear side are fixed. On the other hand, the motor 43 and support 44 of the first rotary drive mechanism 41 on the lower side are fixed on the sliding base 77 on the rear side, and the motor 43 and support 44 of the second rotary drive mechanism 42 on the front side are fixed on the upper side via the base member 78.

[0071] Furthermore, by moving the front sliding base 77 diagonally downward and the rear sliding base 77 diagonally upward, thus... Figure 10 As shown, a pair of first rotating tools 31 approach each other in the vertical direction, while a pair of second rotating tools 32 separate from each other in the front-back direction. The front sliding base 77 moves obliquely upwards, and the rear sliding base 77 moves obliquely downwards, thus... Figure 11 As shown, a pair of first rotating tools 31 are separated from each other in the vertical direction, while a pair of second rotating tools 32 are approaching each other in the front-back direction. It should be noted that... Figure 10 as well as Figure 11 In the diagram, the suspended plane on which a pair of first rotating tools 31 move in parallel is shown as plane K1, and the suspended plane on which a pair of second rotating tools 32 move in parallel is shown as plane K2.

[0072] It should be noted that when the pair of first rotating tools 31 approach and separate from each other in the vertical direction, they also approach and separate in the front-back direction. The same applies to the pair of second rotating tools 32. In addition, the upper first rotating tool 31 and the rear second rotating tool 32 move in a way that advances and retreats relative to the space between the connecting wall 25S of the bridge-shaped body 25 and the wire guiding member 20 (see Figure 6).

[0073] It should be noted that in the above embodiment, the first rotary drive mechanism 41 and the second rotary drive mechanism 42 of one party are fixed to a common sliding base 77 and move in groups, but this is not limited to this, and the structure can also be as follows. Specifically, for example, one of the pair of sliders 76 provided on the guide rail 72 may have only the sliding base of the first rotary drive mechanism 41 fixed to one slider 76, while the other slider 76 may have only the sliding base of the second rotary drive mechanism 42 fixed to one slider 76, and the two sliding bases may be moved using different drive sources. The same applies to the first rotary drive mechanism 41 and the second rotary drive mechanism 42 of the other party.

[0074] It should be noted that in the above embodiment, the sliding base 77 slides through the ball screw 73 and the ball nut 75, but any structure that can make the sliding base 77 move can be any construction, for example, it can also be made to slide through a rack and pinion mechanism.

[0075] It should be noted that in the above embodiment, the pair of sliding bases 77 are configured to move in a direction that is inclined at an angle of 45° relative to the vertical and horizontal directions and the front and back directions in a plane parallel to the main plane of the support wall 14. However, the angle is not limited to this angle. For example, it can be appropriately changed according to the shape of the wire 90 or the inclination of the pair of rotating tools 31 and the pair of rotating tools 32.

[0076] The above is a description related to the structure of the wire coating removal device 10. Next, the structure of the wire forming machine 80 will be described. Figure 1 As shown, the wire forming machine 80 is also equipped with a wire supply device 81 capable of supplying wire 90. Furthermore, the wire 90 supplied from the wire supply device 81 is fed to the processing table S through the guide hole of the sleeve shaft 82. Figure 9 As shown, the processing table S is equipped with multiple forming tools 83 capable of clamping and bending the wire 90, and a cutting tool 84 capable of cutting the wire 90. The aforementioned wire-shaped product 91 is formed sequentially through these tools.

[0077] It should be noted that in this embodiment, the wire supply device 11 of the wire coating removal device 10 and the wire supply device 81 of the wire forming machine 80 have wire supply paths R on the same straight line, but it is not limited to this. The wire supply paths R of the wire coating removal device 10 and the wire supply paths R of the wire forming machine 80 can also be staggered vertically, and can also face different directions when viewed from above.

[0078] The above is a description of the structure related to the wire forming system 100. Next, the effects of the wire coating removal device 10 and the wire forming system 100 will be explained. When the wire forming system 100 is stopped, in the wire coating removal device 10, a pair of first rotating tools 31 and a pair of second rotating tools 32 are positioned together at the origin position away from the wire supply path R. In this state, the wire 90 passes through the wire supply path R of the wire coating removal device 10, and its leading end is inserted into a pair of rollers 12 of the wire supply device 11. Then, when the wire coating removal device 10 is started, the pair of first rotating tools 31 approach and abut against the upper and lower surfaces of the wire 90 at the first break 21 of the wire guide member 20 (see Figure 6(A) and...). Figure 10 At this point, the pair of second rotating tools 32 separate and laterally separate from the wire 90. In this state, the wire supply device 11 supplies a predetermined length of wire 90. As a result, a predetermined length of the coating 90B is removed from both the upper and lower surfaces of the wire 90, forming a pair of first exposed surfaces 94A.

[0079] After a pair of first exposed surfaces 94A are formed, a pair of first rotating tools 31 separate from the wire 90, and a pair of second rotating tools 32 approach and come close to the wire 90. Then, when one end of the first exposed surface 94A reaches the second disconnection portion 22 of the wire guide member 20, the pair of second rotating tools 32 abut against both transverse surfaces of the wire 90 (see Figure 6(B)). Figure 11 At this point, the pair of first rotating tools 31 separate and move vertically away from the wire 90. In this state, the wire supply device 11 supplies a predetermined length of wire 90. As a result, a predetermined length of coating 90B is removed from both transverse sides of the wire 90, forming a pair of second exposed surfaces 94B. Thus, exposed surfaces 94, composed of a pair of first exposed surfaces 94A and a pair of second exposed surfaces 94B, are formed on the wire 90. After forming the pair of second exposed surfaces 94B, the pair of first rotating tools 31 and the pair of second rotating tools 32 return to their original positions. Then, the wire coating removal device 10 repeats the above operation, so that exposed surfaces 94 are formed on the wire 90 at predetermined intervals L0.

[0080] After the wire 90 extends a predetermined length from the wire coating removal device 10 toward the wire forming machine 80, the wire 90 is picked up by the wire supply device 81 of the wire forming machine 80, such as... Figure 1As shown, the wire 90 is in a flexed state between the wire coating removal device 10 and the wire forming machine 80. Specifically, a wire 90 of at least the unfolded length of a wire forming product 91 (i.e., the amount corresponding to the aforementioned predetermined interval L0) is arranged between the wire supply devices 11 and 81, relative to the distance between the devices of the wire coating removal device 10 and the wire forming machine 80. Then, the wire coating removal device 10 and the wire forming machine 80 operate synchronously, such that the time for one cycle of the wire coating removal device 10 processing and supplying the exposed surface 94 on one amount of wire 90 of the wire forming product 91 is the same as the time for one cycle of the wire forming machine 80 forming one wire 90. Thus, the wire coating removal device 10 and the wire forming machine 80 repeatedly perform certain operations to sequentially produce wire forming products 91. Here, the wire coating removal device 10 and the wire forming machine 80 each have wire supply devices 11 and 81, and the wire 90 flexes between the wire coating removal device 10 and the wire forming machine 80. Therefore, in one cycle, the wire coating removal device 10 and the wire forming machine 80 do not have to wait for the other, and the wire coating removal device 10 and the wire forming machine 80 operate smoothly.

[0081] As explained above, the wire coating removal apparatus 10 of this embodiment can process a pair of first exposed surfaces 94A facing the vertical direction (first direction) and a pair of second exposed surfaces 94B facing the longitudinal direction (second direction) of the wire 90 at any position along the length of the wire 90. That is, the wire coating removal apparatus 10 of this embodiment can process exposed surfaces 94 on the wire 90 that cannot be achieved in conventional wire coating removal apparatuses. Furthermore, the wire 90 is stabilized by the wire guide member 20 supporting both sides of the processed portion, thus improving processing accuracy. Additionally, the wire 90 and the guide hole 20H of the wire guide member 20 through which it passes are quadrilateral in cross-section, thus preventing rotation and twisting of the wire 90 around its axis during processing, thereby improving processing accuracy. Moreover, the wire coating removal apparatus 10 itself has a wire supply device 11 for supplying the wire 90, thus improving the positional accuracy of the processed portion along the length of the wire 90. In addition, in the wire forming system 100 of this embodiment, the wire coating removal device 10 and the wire forming machine 80 are respectively equipped with wire supply devices 11 and 81. A slack of wire 90 is provided between the wire coating removal device 10 and the wire forming machine 80, so that one of the wire coating removal device 10 and the wire forming machine 80 does not need to wait for the other, and can efficiently manufacture wire formed articles 91 from wire 90.

[0082] However, although it is also possible to have a first tool spacing changing mechanism that changes the spacing of a pair of first rotating tools 31 in a first direction (specifically, the up-down direction) and a second tool spacing changing mechanism that changes the spacing of a pair of second rotating tools 32 in a second direction (specifically, the front-back direction) so that the pair of first rotating drive mechanisms 41 that drive the first rotating tools 31 move parallel to the first direction and the pair of second rotating drive mechanisms 42 that drive the second rotating tools 32 move parallel to the second direction (hereinafter referred to as "simple movement structure"), in such a simple movement structure, in order to avoid mutual interference between the pair of first rotating drive mechanisms 41 and the pair of second rotating drive mechanisms 42, the size of the first rotating drive mechanism 41 and the second rotating drive mechanism 42 is strictly limited. In contrast, if the first tool spacing changing mechanism and the second tool spacing changing mechanism are configured as in this embodiment, such that the first rotating tool 31 of one side and the second rotating tool 32 of the other side move together, and the first rotating tool 31 of the other side and the second rotating tool 32 of the other side move together, then the interference between the first rotating drive mechanism 41 and the second rotating drive mechanism 42 can be easily avoided, and the limitations on their size and structure are mitigated.

[0083] It should be noted that in this embodiment, the pair of first exposed surfaces 94A and the pair of second exposed surfaces 94B are arranged at the same position along the length of the wire 90, but they can also be arranged at separate positions. In addition, in this embodiment, the first direction (vertical direction) in which the pair of first rotating tools 31 approach / separate to process the pair of first exposed surfaces 94A is orthogonal to the direction (front-back direction) in which the pair of second rotating tools 32 approach / separate to process the pair of second exposed surfaces 94B, but they can also intersect at an angle other than 90 degrees.

[0084] Furthermore, the pair of first rotating tools 31 and the pair of second rotating tools 32 can also be driven to rotate by a shared rotary drive mechanism. Regarding the structure in which the pair of first rotating tools 31 are driven to rotate by the shared rotary drive mechanism, consider a structure in which the pair of first rotating tools 31 rotate around a shared rotating body (gear, pulley). The same applies to the second tool spacing changing mechanism that alters the spacing between the pair of second rotating tools 32.

[0085] It should be noted that, in this embodiment, an exposed surface 94 consisting of a pair of first exposed surfaces 94A and a pair of second exposed surfaces 94B is described as an example. However, for example, an exposed surface may also be formed by either the pair of first exposed surfaces 94A or the pair of second exposed surfaces 94B. In other words, the wire coating removal apparatus 10 according to this embodiment can form various exposed surfaces, such as an exposed surface 94 consisting of a pair of first exposed surfaces 94A and a pair of second exposed surfaces 94B, an exposed surface consisting of only a pair of first exposed surfaces 94A, and an exposed surface consisting of only a pair of second exposed surfaces 94B.

[0086] [Second Implementation]

[0087] The following is about Figures 12-14 The wire coating removal apparatus 10A of this embodiment will be described. In this wire coating removal apparatus 10A, a pair of support walls 14A and 14B are provided, standing upright from the top plate 60A and facing each other in the wire supply direction H1. Furthermore, on the upstream side of the opposing surface of the pair of support walls 14A and 14B, on the opposing surface of the support wall 14A, as shown... Figure 13 As shown, a pair of sliding mechanisms 70A are provided as a first tool spacing changing mechanism to change the distance between the pair of first rotating tools 31. On the opposing surface of the downstream support wall 14B, as shown... Figure 14 As shown, a pair of sliding mechanisms 70B are provided as a second tool spacing changing mechanism to change the spacing between a pair of second rotating tools 32. The basic structure of the sliding mechanisms 70A and 70B is the same as that of the sliding mechanism 70 in the first embodiment, and the parts with the same structure as in the first embodiment are marked with the same reference numerals as in the first embodiment.

[0088] like Figure 13 As shown, on the opposing surface of the support wall 14A on the upstream side, a pair of sliding mechanisms 70A are arranged in the front-rear direction across the wire supply path R, and are configured such that the sliding base 77 of each sliding mechanism 70A slides up and down. Furthermore, a first rotary drive mechanism 41 for driving the first rotary tool 31 to rotate is respectively installed on the sliding base 77 of each sliding mechanism 70A.

[0089] like Figure 14 As shown, on the opposite surface of the support wall 14B on the downstream side, a pair of sliding mechanisms 70B are arranged vertically across the wire supply path R, and the sliding base 77 of each sliding mechanism 70B is configured to slide in the front-back direction. Furthermore, a second rotary drive mechanism 42 for driving the second rotary tool 32 to rotate is respectively installed on the sliding base 77 of each sliding mechanism 70B.

[0090] The wire coating removal apparatus 10A of this embodiment is the same as the wire coating removal apparatus 10 of the first embodiment except for the structure described above, and processes the wire 90 in the same manner as the wire coating removal apparatus 10 of the first embodiment. It should be noted that in a simple moving structure like this embodiment, the size and structure of the first rotary drive mechanism and the second rotary drive mechanism are strictly limited in order to avoid interference between the pair of first rotary drive mechanisms and the pair of second rotary drive mechanisms. However, in the structure of the first embodiment, such limitations are mitigated.

[0091] [Other Implementation Methods]

[0092] (1) In the first and second embodiments described above, the first tool spacing changing mechanism for changing the distance between a pair of first rotating tools 31 includes a pair of sliding mechanisms 70 (or a pair of sliding mechanisms 70A), which are driven by different drive sources (servo motors 74 with reducers), but may also be driven by a common drive source. The same applies to the second tool spacing changing mechanism for changing the distance between a pair of second rotating tools 32.

[0093] (2) Specifically, it can also be as follows Figure 15 As shown in the first tool spacing changing mechanism 110, for example, a first rotary drive mechanism 41 for driving a pair of first rotary tools 31 is mounted on a pair of sliding members 76 that are slidably engaged with a common guide rail 72. A pair of racks 99, separately fixed to the pair of sliding members 76 and extending parallel to the guide rail 72, are arranged opposite each other. Furthermore, a pinion 98 is provided that is clamped and meshed with the pair of racks 99, and the pinion 98 is driven to rotate by a motor 97. The same applies to the second tool spacing changing mechanism.

[0094] (3) Alternatively, it can be as follows Figure 16 Similar to the first tool spacing changing mechanism 111 shown, instead of the aforementioned pair of racks 99 and pinions 98, a timing belt 114 is installed between a pair of pulleys 113. A pair of opposing portions 114A of the timing belt 114 are configured to extend parallel to the guide rail 72 and to fix a pair of sliding members 76 to the opposing portions 114A. One of the pulleys 113 is driven to rotate by a motor 97. The same applies to the second tool spacing changing mechanism.

[0095] (4) In the first and second embodiments described above, the pair of first rotating tools 31 are driven to rotate by different drive sources, but they can also be driven to rotate by a common drive source. Specifically, a pair of output gears that rotate integrally with the pair of first rotating tools 31 can be directly or via an idler gear connected to an input gear driven by a motor, so that the pair of first rotating tools 31 are driven to rotate by a single motor, and the interval between the pair of first rotating tools 31 can be changed by changing the position of the center of the pair of output gears relative to the input gear. Alternatively, a pair of output pulleys that rotate integrally with the pair of first rotating tools 31 can be connected to an input pulley driven by a motor using a synchronous belt, so that the pair of first rotating tools 31 are driven to rotate by a single motor, and the interval between the pair of first rotating tools 31 can be changed by changing the position of the center of the pair of output pulleys relative to the input pulley. The same applies to the pair of second rotating tools 32.

[0096] (5) For the motors in the above embodiments, the motors that drive the first rotating tool 31 and the second rotating tool 32 to rotate can be electric motors or pneumatic motors.

[0097] It should be noted that specific examples of the technology included in the technical solution are disclosed in this specification and the accompanying drawings, but the technology described in the technical solution is not limited to these specific examples, and also includes various modifications and alterations to the specific examples, as well as methods that extract a part of the specific examples separately.
