Description

  The present invention relates to a wire processing system and a wire processing method for manufacturing a wire subjected to a predetermined surface processing.

  A medical wire such as a guide wire is manufactured by being subjected to various processes so as to have desired characteristics (high delivery performance in a living body lumen). For example, Patent Document 1 discloses a wire processing system that changes the rigidity of a wire in the axial direction by rotating the wire of a predetermined length around the axis and grinding the surface thereof.

  By the way, in the manufacture of the wire, the post-processing is further performed on the wire subjected to the surface processing as described above. For example, a medical guide wire is subjected to post-processing steps such as cleaning the wire, shaping the wire, and coating an outer layer according to the characteristics to be manufactured. This type of post-processing has a problem that it takes time and effort because it individually processes a plurality of wires having a predetermined length.

  For this reason, Patent Document 2 discloses that the surface of the wire is ground by rotating the wire and the bobbin together while the wire, which is the material of the wire, is pulled out from one bobbin and wound around the other bobbin. An apparatus has been proposed. Thereby, since a wire is not cut | disconnected in implementation of surface processing, it becomes possible to perform a post-process efficiently to the continuous wire after surface processing.

  However, the apparatus disclosed in Patent Document 2 is configured to rotate a bobbin wound around the wire in the circumferential direction in a direction orthogonal to the circumferential direction (a direction different from the axis of the bobbin axis) during conveyance of the wire. It has become. In this case, when the bobbin is rotated at a high speed, the bobbin is relatively heavy, so that the bobbin itself is shaken, and the wire material is entangled, and it is easy to cause inconveniences such as difficulty in feeding and winding the wire material. After all, even with the apparatus disclosed in Patent Document 2, it is necessary to rotate the bobbin and the wire at a low speed, and it takes time for the surface processing, and it is difficult to improve the manufacturing efficiency.

  The present invention has been made in order to solve the above-described problems, and enables a continuous wire rod to be rotated at a high speed with a simple configuration, thereby improving the work efficiency of the entire wire manufacturing process. And it aims at providing a wire processing method.

  In order to achieve the above object, the present invention includes a first bobbin rotating portion that rotates a first bobbin wound with a wire around a first axis that is an axis of the first bobbin, A feeding portion that feeds the wire coaxially with the first axis, and a second bobbin rotation that rotates the second bobbin around the second axis that is the axis of the second bobbin and coaxially with the first axis A winding portion that draws the wire rod fed from the feeding portion coaxially with the second axis and winds the wire rod around the second bobbin, and a straight line between the feeding portion and the winding portion. A surface processing portion that forms a processed region by performing a predetermined surface processing on the surface of the wire extending in a shape, and the first bobbin rotating portion includes the first bobbin rotating portion and the second bobbin rotating portion. And by rotating the second bobbin in synchronization with each other, And forming the processed region on the wire.

  According to the above, in the wire processing system, the first axial center of the first bobbin and the second axial center of the second bobbin rotate coaxially during surface processing, so that the linearly extending wire rod can be rotated around the axis. It can be rotated at high speed. Thereby, it becomes possible to shorten the work time of the surface processing with respect to a wire. Moreover, since the continuous wire is not cut in the surface processing step, post-processing can also be performed efficiently. Therefore, the work efficiency can be greatly improved as a whole wire manufacturing process.

  In this case, according to the present invention, the linearly extending wire can be rotated around the axis at a rotation speed of 3000 rpm or more, and further 4000 rpm or more is possible.

  Moreover, in the wire processing system of this invention, it is preferable to rotate the said linearly extended wire at the rotational speed of 4000 rpm to 12000 rpm, and it is further more preferable to rotate at the rotational speed of 5000 rpm to 10,000 rpm.

  Thereby, processing efficiency improves dramatically.

  In this case, it is preferable to have a wire rod rotation drive unit that is disposed between the feeding unit and the winding unit and that grips the wire and applies a rotational force.

  Thus, by grasping the wire by the wire rotation driving unit, the slack of the wire can be suppressed between the feeding unit and the winding unit, and the rotation of the wire can be further increased. Moreover, surface processing can be accurately performed by rotating the wire near the processing device of the surface processing portion.

  In addition to the above configuration, the wire rotation driving unit may match the rotation speed of the gripped wire with the rotation speed of the first and second bobbins during the surface processing.

  Thus, the rotation speed of the wire rod by the wire rod rotation driving unit matches the rotation speed of the first and second bobbins, so that the wire rod is prevented from being twisted during the rotation of the wire rod. Can be carried out satisfactorily.

  The wire processing unit includes a fixed base provided with a processing device for the surface processing part, a movable base provided with the feeding part and the winding part, and movable relative to the fixed base. In the surface processing, it is preferable to move in synchronization with the movement of the movable table.

It is preferable to alternately repeat the wire rod feeding step and the wire rod conveying step of simultaneously winding the wire rod around the second bobbin.

  In this way, by alternately repeating the processing step and the wire conveying step, in the processing step, the surface processing can be performed intensively on the wire while rotating the wire itself. It is possible to smoothly carry out and wind up. Therefore, the processed region can be formed more easily and with high accuracy.

  The feeding portion includes a first rotor member that can be coaxially rotated relative to the first bobbin, and the winding portion is a second rotor member that is relatively rotatable coaxially to the second bobbin. And the control unit integrally rotates the first bobbin and the first rotor member and rotates the second bobbin and the second rotor member integrally at the time of the processing step. During the transfer process, the first rotor member is rotated relative to the first bobbin to feed out the wire from the first bobbin, and the second rotor member is rotated relative to the second bobbin. It is preferable that the wire having the processed region is wound around the second bobbin.

  As described above, in the processing step, the wire rod can be easily rotated by rotating the first bobbin and the first rotor member integrally and simultaneously rotating the second bobbin and the second rotor member. . In the wire rod conveying step, the wire rod is fed out by the relative rotation of the first rotor member with respect to the first bobbin, and the wire rod is wound based on the relative rotation of the second rotor member with respect to the second bobbin, thereby conveying the wire rod more smoothly. be able to.

  Further, the first bobbin rotating part is disposed in the first outer shaft so as to be rotatable relative to the first outer shaft to which the first bobbin is coupled and the first outer shaft. And the second bobbin rotating part includes a second outer shaft to which the second bobbin is connected, and the second outer shaft rotatably relative to the second outer shaft. It is good to provide the 2nd inner side shaft arrange | positioned in a shaft and to which the said 2nd rotor member is connected.

  As described above, the first bobbin rotating portion includes the first outer shaft and the second inner shaft, so that the first bobbin and the first rotor member can be smoothly rotated relative to each other. Similarly, when the second bobbin rotating portion includes the second outer shaft and the second inner shaft, the second bobbin and the second rotor member can be smoothly rotated relative to each other.

  Still further, the first and second rotor members guide the wire rod to a center insertion portion for guiding the wire rod to the first and second shaft centers, respectively, and to a position shifted radially outward from the center insertion portion. It is preferable to have an eccentric insertion part.

  Thus, a 1st and 2nd rotor member has a center insertion part and an eccentric insertion part, and can guide a wire easily between the 1st and 2nd axial center and the position shifted to the diameter direction outside. Can do. Thereby, the feeding of the wire material in the feeding portion and the winding of the wire material in the winding portion can be performed more efficiently.

  In order to achieve the above object, the wire processing method according to the present invention is such that one end side is wound around a first bobbin and the other end side is attached to a second bobbin, and the first bobbin and the second bobbin are made of wire. A processing step of forming a processed region by subjecting the wire to a predetermined surface processing while rotating a portion between the first bobbin and the second bobbin.

The passage 55 communicates with an upstream opening 55 a provided at the upstream end 54 a and a downstream opening 55 b provided at the downstream end 54 b and having a slightly larger diameter than the wire 20. The downstream opening 55b functions as a center insertion portion that feeds the wire 20 overlapping the feeding bobbin side axis 43 (extension line L of the conveyance path D). The upstream opening 55a functions as an eccentric insertion portion that draws the wire 20 from the feeding bobbin 40 at a position shifted radially outward from the downstream opening 55b. The rotor member 48 may have a mechanism for relatively displacing the guide tube 54 in the direction of the arrow X during the feeding of the wire 20 (at the time of a wire conveyance step described later).

The moving device 80 includes a wheel that can roll on the guide rail 78 and a drive source that rotates the wheel (both not shown). The moving device 80 is displaced on the guide rail 78 in synchronization with the movement of the movable table 36 under the control of the control unit 32. For example, when the movable base 36 moves toward the X1 side at a predetermined distance and a predetermined speed, the moving device 80 also moves toward the X1 side at the same timing and the same speed.

With. Further, a guide body 90 for inserting and guiding the wire 20 is provided in a proximity position upstream of the grindstone 86.

  The grindstone 86 is provided with, for example, a plurality (a pair) of disc-shaped ones, and is rotated at a predetermined speed by the grindstone driving mechanism 88 controlled by the control unit 32 and advances and retreats so as to narrow or widen the mutual gap. Then, the pair of grindstones 86 performs grinding by contacting the surface of the wire 20 by narrowing the gap by a predetermined amount at a predetermined timing when the wire 20 passes through the gap. The guide body 90 and the holding body 84 suppress the blurring of the wire 20 around the grindstone 86 when the wire 20 is ground. Thereby, the processed region 92 (for example, the taper part in FIG. 1B) is formed in the wire 20. In addition, the structure of the processing apparatus 74 is not limited to the above structure, You may apply the various apparatus which can give surface processing to the wire 20. FIG.

  On the other hand, the wire support mechanism 76 hold | maintains the surface of the wire 20 so that rotation is possible, and suppresses that the wire 20 moves wildly. The wire support mechanism 76 can move forward and backward in the transport path D of the wire 20 and has a plurality of sliding plate portions 94 provided in parallel along the axial direction of the guide rail 78. The plurality of sliding plate portions 94 have an upper sliding portion 94a and a lower sliding portion 94b that face each other and sandwich the wire 20 therebetween. The plurality of sliding plate portions 94 are individually controlled by the control unit 32 to open and close the upper sliding portion 94a and the lower sliding portion 94b.

  The upper sliding portion 94a and the lower sliding portion 94b of the sliding plate portion 94 support the wire 20 with a low frictional force. As a constituent material of the upper sliding portion 94a and the lower sliding portion 94b, for example, polyacetal, fluorine resin, or the like may be applied. The wire support mechanism 76 is not particularly limited, and may take various configurations that can support the wire 20 lightly and allow rotation about its axis. For example, the wire support mechanism 76 may be formed in a groove that can accommodate the wire 20.

  The processing device 74, the moving device 80, and the wire support mechanism 76 of the surface processing unit 28 set the position (height) in the arrow Y direction of the portion through which the wire 20 is passed so that the transport path D of the wire 20 is linear. Has been. Further, the winding unit 30 is also configured to draw out the wire 20 extending linearly with the height sent from the surface processing unit 28.

  As shown in FIG. 3, the winding unit 30 of the wire rod processing apparatus 22 winds the wire rod 20 having a processed region 92 in which a winding bobbin 96 (second bobbin) is set and surface processing is performed by the processing device 74. Take up the take-up bobbin 96. The winding portion 30 is symmetrical with the feeding portion 26 with the center portion in the arrow X direction of the wire rod processing apparatus 22 as a base point.

  Specifically, the winding unit 30 includes an attachment portion 98 on the X2 side, and includes a winding portion side rotation mechanism 100 (second bobbin rotation portion) on the X1 side of the attachment portion 98. A winding bobbin 96 is attached to the outer peripheral surface of the attachment portion 98. When the take-up bobbin 96 is mounted on the outer peripheral surface of the attachment portion 98, the take-up bobbin side axial center 103 (second axis) is aligned with the attachment portion 98 and the outer shaft 110 described later. . The winding bobbin side axial center 103 coincides with the extension line L of the conveying path D of the wire 20 in the surface processing portion 28, and the winding bobbin 96 is a surface located coaxially with the winding bobbin side axial center 103. It rotates integrally with the wire 20 of the processing portion 28.

  A rotor member 104 (second rotor member) is provided in the vicinity of the take-up bobbin 96 on the X2 side of the attachment portion 98. A passage 107 is formed in the guide tube 106 of the rotor member 104. The guide tube 106 has an upstream end 106a and an upstream opening 107a on the X2 side, and has a downstream end 106b and a downstream opening 107b on the X1 side and outside the take-up bobbin 96, and from the center toward the X1 side. Looking diagonally outward. The upstream opening 107a functions as a center insertion portion that overlaps the winding bobbin side axial center 103 (extension line L of the conveyance path D) and receives the wire 20. The downstream opening 107b functions as an eccentric insertion portion that winds the wire 20 around the winding bobbin 96 at a position shifted radially outward from the upstream opening 107a. That is, as the rotor member 104 rotates, the guide tube 106 applies a tensile force to the wire 20 connected to the take-up bobbin 96 and winds the upstream wire 20 around the take-up bobbin 96.

  The winding unit side rotating mechanism 100 includes a housing 108, an outer shaft 110 (second outer shaft), an inner shaft 112 (second inner shaft), a first motor 114, and a second motor, like the feeding unit side rotating mechanism 46. A motor 116 and a rotation transmission unit 118 are included. The first and second motors 114 and 116 rotate the mounting portion 98 at the same direction and at the same speed as the rotation direction of the first and second motors 62 and 64 of the feeding portion 26, and as viewed from the X1 side, The winding bobbin 96 is rotated in the same direction as the feeding bobbin 40. The control unit 32 matches the rotation speeds and rotation timings of the first and second motors 62 and 64 of the feeding unit 26 with the first and second motors 114 and 116 of the winding unit 30. Thereby, while suppressing the twist of the wire 20, the wire 20 can be rotated, and the wire 20 can be smoothly transferred between the feeding bobbin 40 and the take-up bobbin 96.

  Returning to FIG. 2, a computer having an arithmetic processing unit, a storage unit, and an input / output unit (not shown) is applied to the control unit 32 of the wire rod processing apparatus 22. The arithmetic processing unit of the control unit 32 executes the control program stored in the storage unit to link the feeding unit 26, the surface processing unit 28, the winding unit 30, and the movable base 36, Carry out surface processing.

  Further, the post-processing device 24 includes a feeding unit 120, a cleaning unit 122, a shaping unit 124, an outer layer forming unit 126, and a cutting unit 128. The feeding unit 26 feeds the wire 20 having the processed region 92 formed by the wire processing apparatus 22 to the downstream side (the cleaning unit 122, the shaped portion 124, the outer layer forming unit 126, and the cutting unit 128). The cleaning unit 122 removes dust and the like attached to the continuous wire 20. The shaped portion 124 forms the bent portion 14 (see FIG. 1A) in a predetermined range of the wire 20. The outer layer forming portion 126 forms the covering portion 18 (see FIG. 1B) over a predetermined range or the entire wire 20. Further, the cutting part 128 cuts the wire 20 on which the bent part 14 and the covering part 18 are formed according to the entire length of the guide wire 12 to be manufactured, and appropriately processes the cut end part. In addition, the structure of the post-processing apparatus 24 is not specifically limited, The appropriate function part should just be provided according to the wire to be manufactured.

  The wire processing system 10 according to the present embodiment is basically configured as described above. Hereinafter, a manufacturing flow (wire processing method) by the wire processing system 10 will be described.

  The wire processing system 10 performs a pre-processing process in which surface processing is performed on the wire 20 by the wire processing apparatus 22 and a post-processing process and a cutting process are performed on the wire 20 by the post-processing apparatus 24 in the manufacture of the wire. As shown in FIG. 5, in the pre-processing step by the wire rod processing device 22, control is performed to alternately repeat the processing step (machining step) for surface processing of the wire rod and the wire rod conveying step (wire rod conveying step) for conveying the wire rod. Do.

  Before the start of the pre-processing step, the operator attaches the feeding bobbin 40 to the attachment portion 44 of the feeding portion 26 and attaches the take-up bobbin 96 to the attachment portion 98 of the take-up portion 30. Further, the operator pulls the wire 20 wound around the feeding bobbin 40 through the guide tube 54 of the feeding unit 26 toward the surface processing unit 28. Further, the operator pulls the wire 20 through the conveying path D constituted by the moving device 80 of the surface processing unit 28, the wire support mechanism 76, and the processing device 74 to the winding unit 30, and in the guide tube 106 of the winding unit 30. To the unwound portion (outer peripheral surface) of the take-up bobbin 96. After this preparation, the wire rod processing apparatus 22 starts operation.

  After performing a predetermined initial operation (operation check, synchronization adjustment, etc.), the wire processing apparatus 22 starts a pre-processing step (processing step, wire transport step). In the processing step, the control unit 32 integrally controls the surface processing unit 28 and the movable base 36 to perform surface processing on the wire 20.

  As shown in FIG. 2, in the processing step, first, the moving device 80 (spindle 82) waiting at the upstream position S1 of the guide rail 78 grips the wire 20 inserted through the through hole 82a. Moreover, the control part 32 supports the surface of the wire 20 with a light force by closing all the sliding board parts 94 of the wire support mechanism 76. FIG. In the gripping state of the moving device 80, the control unit 32 rotates the spindle 82 by the rotation driving source 80a to rotate the gripping wire 20.

  When the spindle 82 rotates, the control unit 32 simultaneously drives the first and second motors 62 and 64 of the feeding unit 26 and the first and second motors 114 and 116 of the winding unit 30 to rotate. In this case, the control unit 32 rotates both the first and second motors 62 and 64 of the feeding unit 26 in a predetermined direction (for example, clockwise) as viewed from the X2 side arrow from the center in the arrow X direction. In addition, the control unit 32 moves the first and second motors 114 and 116 of the winding unit 30 in the opposite direction (reverse to the first and second motors 62 and 64) as viewed from the X1 side from the center in the arrow X direction. Rotate clockwise.

  Each motor 62, 64, 114, 116 is controlled to the same rotational speed as the rotational speed of the spindle 82. As a result, the rotation of the wire 20 by the spindle 82, the rotation of the feeding bobbin 40 and the rotor member 48 of the feeding unit 26, and the rotation of the winding bobbin 96 and the rotor member 104 of the winding unit 30 are all synchronized (of the wire processing apparatus 22). Rotate counterclockwise as viewed on the X1 arrow). As a result, the wire 20 is rotated around the axis stably and at high speed (counterclockwise). The rotation direction of the wire 20 may be the reverse direction (clockwise).

  As shown in FIG. 6A, the control unit 32 moves the moving device 80 to the X1 side of the wire 20 while rotating the wire 20 itself around the axis as described above. Move in the direction. The moving device 80 and the movable table 36 move at the same speed. Therefore, although the wire 20 moves to the X1 side with respect to the fixed base 34, the wire 20 does not move with respect to the movable base 36. Therefore, the wire 20 is fed out from the feeding unit 26 and is wound without winding the wire 20 in the winding unit 30 (that is, the conveyance of the wire 20 between the feeding unit 26 and the winding unit 30). Surface processing is performed on the wire 20.

  When the moving device 80 and the movable table 36 are moved, the control unit 32 grinds the surface of the wire 20 by narrowing the gap between the pair of grindstones 86 of the processing device 74 at a predetermined timing. For example, when the guide wire 12 shown in FIG. 1A forms a tapered portion (processed region 92) that gradually tapers, the control unit 32 narrows the gap between the grindstones 86 at the beginning of grinding, Control is performed to gradually widen the gap as 80 advances. Thereby, from the downstream side of the holding body 84 of the processing apparatus 74, the wire 20 which has the processed area | region 92 over a predetermined range is sent out.

  The plurality of sliding plate portions 94 of the wire support mechanism 76 lightly support the wire 20 during rotation of the wire 20, thereby preventing the wire 20 from rotating during rotation while allowing the wire 20 to rotate. As the moving device 80 approaches each sliding plate portion 94, the control unit 32 opens the upper sliding portion 94a and the lower sliding portion 94b in sequence to allow the moving device 80 to pass.

  As shown in FIG. 6B, when the moving device 80 reaches the downstream position S2 of the guide rail 78 (the proximity position of the guide body 90), the control unit 32 stops the movement of the moving device 80 and the movable table 36. And the moving apparatus 80 accept | permits the movement of the wire 20 in the following wire conveyance step by making the wire 20 into a non-gripping state. The moving device 80 and the movable base 36 move to the upstream side in the transport direction at an appropriate timing (before or during the wire transport step), and return to the original upstream position S1. Note that a temporary standby period may be provided between the processing step and the wire rod conveyance step, and the moving device 80 and the movable table 36 may return during this period. Further, the movement of the moving device 80 and the movable table 36 to the upstream side in the transport direction may be performed simultaneously or separately.

  In the wire conveyance step, the control unit 32 rotationally drives the second motor 64 of the feeding unit 26 and the second motor 116 of the winding unit 30 to rotate the rotor members 48 and 104 of the feeding unit 26 and the winding unit 30. By doing so, the wire 20 is conveyed. That is, the feeding of the wire 20 by the feeding unit 26 and the winding of the wire 20 by the winding unit 30 are performed simultaneously.

  In this case, in the feeding portion 26, the rotation shaft 64 a of the second motor 64 is rotated in a predetermined direction (a direction opposite to the winding direction of the wire 20 of the feeding bobbin 40), and the inner shaft 60 is moved relative to the outer shaft 58. Rotate. As a result, the rotor member 48 connected to the inner shaft 60 rotates relative to the non-rotating feeding bobbin 40 connected to the outer shaft 58. Therefore, the guide tube 54 turns around the outside in the radial direction of the feeding bobbin 40, draws the wire 20, inserts it into the passage 55 from the upstream opening 55 a, and sends it out from the downstream opening 55 b through the passage 55.

  The wire 20 delivered from the feeding unit 26 passes through the surface processing unit 28 and is wound around the winding unit 30. In the wire conveyance step, the surface processing unit 28 can pass through the wire 20 smoothly. That is, the spindle 82 of the moving device 80 and the sliding plate portion 94 of the wire support mechanism 76 bring the wire 20 into a non-gripping state, and the pair of grindstones 86 of the processing device 74 are separated from each other. As a result, a large frictional force is suppressed from being applied to the wire 20.

  In the winding unit 30, the rotation of the second motor 116 is controlled by the control unit 32 in the direction opposite to the second motor 64 of the feeding unit 26 and at the same rotational speed as the second motor 64. As the second motor 116 rotates in this manner, the rotor member 104 of the winding unit 30 rotates relative to the non-rotating winding bobbin 96 via the inner shaft 112. As a result, the wire 20 (including the processed region 92) sent from the surface processing portion 28 and directed from the upstream opening 107 a of the guide tube 106 to the downstream opening 107 b through the passage 107 is placed on the outer peripheral surface of the winding bobbin 96. Wrap it around. In addition, if the winding part 30 is the structure which the rotor member 104 displaces relatively to the axial direction of the winding bobbin 96 at the time of winding, it can wind the wire 20 around the winding bobbin 96 more favorably.

  The above wire rod conveyance step is carried out with an execution period set by the control unit 32 so as to be a predetermined movement amount according to the total length of the guide wire 12 to be formed. Therefore, the processing and transport of one wire main body 16 having the processed region 92 and the non-processed region are performed by performing the processing step and the wire conveying step once. And the wire processing apparatus 22 can form the wire main body 16 in multiple in the continuous wire 20 by performing a process step and a wire conveyance step alternately.

  After the pre-processing step, the wire 20 wound around the winding bobbin 96 is removed from the wire processing device 22 by the operator and brought into the post-processing device 24 to perform the post-processing step. In the post-processing step, a cleaning operation for removing dust from the wire 20 having the processed region 92 is performed by the cleaning unit 122. Further, in the post-processing step, a shaping operation for bending the wire 20 by the shaping portion to form the bending portion 14 of the guide wire 12, and an outer layer formation operation for covering the outer peripheral surface of the wire 20 with the covering portion 18 by the outer layer formation portion 126. Is done. In this post-processing step, each operation can be continuously performed on the continuous wire 20, and the work efficiency can be greatly improved.

  Furthermore, a cutting process is performed after a post-processing process. In the cutting step, the wire 20 having the bent portion 14 and the covering portion 18 is cut to a predetermined length by the cutting portion 128 of the post-processing device 24, and the cut end portion of the wire 20 is appropriately processed. Thereby, the wire 20 is manufactured in multiple numbers as the guide wire 12 shown to FIG. 1A by being cut | disconnected for every predetermined length.

  As described above, in the wire processing method and the wire processing system 10, the feeding bobbin side axis 43 of the feeding bobbin 40 and the winding bobbin side axis 103 of the winding bobbin 96 rotate coaxially, so that the transport path D The wire 20 can be rotated around the axis at high speed. For example, the wire rod processing apparatus 22 can rotate the wire rod 20 at 3000 rpm or more during surface processing. In particular, the wire processing system 10 preferably rotates the linearly extending wire 20 at a rotational speed of 4000 rpm to 12000 rpm with the above-described configuration. More preferably, it may be rotated at a rotational speed of 5000 rpm to 10,000 rpm. As a result, sufficient processing accuracy is obtained and the processing efficiency is dramatically improved.

  Here, in the conventional device (see US Pat. No. 7,585,206), the bobbin around which the wire is wound in the circumferential direction is configured to rotate in a direction orthogonal to the circumferential direction. Therefore, the conventional apparatus rotates the wire at a low speed of, for example, about 2000 rpm, and it is difficult to perform surface processing efficiently.

  On the other hand, the wire processing method and the wire processing system 10 according to the present embodiment can rotate the wire 20 itself at high speed, and can shorten the work time of surface processing on the wire 20. Further, since the continuous wire 20 is not cut in the processing step, post-processing can be performed efficiently. Therefore, the work efficiency can be greatly improved as a whole wire manufacturing process.

  In this case, by holding the wire 20 by the spindle 82 of the moving device 80, the slack of the wire 20 can be suppressed between the feeding portion 26 and the winding portion 30, and the rotation of the wire 20 can be further increased. Is possible. Further, by rotating the wire 20 near the processing device 74 of the surface processing unit 28, the surface processing becomes more accurate. Further, since the rotation speed of the wire 20 by the moving device 80 matches the rotation speed of the feeding and winding bobbins 40 and 96, the wire 20 is prevented from being twisted during the rotation of the wire 20, and surface processing is performed. And the conveyance of the wire 20 can be performed satisfactorily. Further, the moving device 80 moves in synchronization with the movement of the movable table 36 during surface processing, so that the wire 20 can be rotated while gripping the wire 20 more firmly, and the processing device 74 of the fixed table 34 can be rotated. On the other hand, the wire 20 can be displaced. Thereby, the processed region 92 can be satisfactorily formed in the predetermined range of the wire 20.

  The wire rod processing apparatus 22 is configured to alternately repeat the wire rod conveying step and the machining step. Thereby, at the time of a process step, surface processing can be favorably performed to the wire 20 by rotating the wire 20 itself. Further, during the wire conveyance step, the wire 20 can be smoothly fed and wound. Further, in the processing step, the wire rod 20 can be easily rotated by rotating the feeding bobbin 40 and the rotor member 48 integrally and rotating the winding bobbin 96 and the rotor member 104 integrally. On the other hand, in the wire rod conveying step, the wire rod 20 is fed by the relative rotation of the rotor member 48 with respect to the feeding bobbin 40 and the wire rod 20 is wound based on the relative rotation of the rotor member 104 with respect to the take-up bobbin 96, thereby making the wire rod 20 smoother. Can be transported.

  Furthermore, since the feeding portion side rotating mechanism 46 includes the outer shaft 58 and the inner shaft 60, the feeding bobbin 40 and the rotor member 48 can be smoothly rotated relative to each other. Similarly, when the winding unit side rotation mechanism 100 includes the outer shaft 110 and the inner shaft 112, the relative rotation of the winding bobbin 96 and the rotor member 104 can be performed smoothly. Furthermore, the rotor members 48 and 104 have a center insertion part (downstream opening 55b and upstream opening 107a) and an eccentric insertion part (upstream opening 55a and downstream opening 107b), so that the wire 20 is shifted to the radially outer side. Easy to guide. Therefore, the feeding of the wire 20 in the feeding portion 26 and the winding of the wire 20 in the winding portion 30 can be performed more efficiently.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the wire rod processing apparatus 22 may include a cleaning unit (not shown) that cleans the wire rod 20 in the conveyance path D of the wire rod 20 between the surface processing unit 28 and the winding unit 30. In this case, the post-processing device 24 does not have to include a cleaning unit.

  Further, for example, the wire rod processing apparatus 22 may be configured to rotate the wire rod 20 by applying the rotating force from the feeding unit 26 and the winding unit 30 without applying the rotating force to the wire rod 20 by the moving device 80. In this case, the surface processing unit 28 may not include the moving device 80. Alternatively, the gripping member that rotates the wire 20 may be configured to be fixed to the movable base 36 and advance and retreat integrally with the movable base 36. Such a configuration simplifies control during surface processing.

  Further, the wire processing apparatus 22 may be configured to rotate the wire 20 itself while conveying the wire 20 and perform surface processing (simultaneously performing a feeding process, a surface processing process, and a winding process). Such a configuration can be realized, for example, by making the rotational speed of the feeding bobbin 40 and the rotational speed of the rotor member 48 different, and making the rotational speed of the winding bobbin 96 and the rotational speed of the rotor member 104 different. it can.
