  First, the conventional manufacturing apparatus disclosed in Patent Document 2 will be described with reference to FIG. 17A and 17B are perspective views showing a conventional manufacturing apparatus.

  The conventional manufacturing apparatus includes a wiring forming machine 1, a control unit 11 that controls driving of the wiring forming machine 1, and a wiring material supply device that supplies a required wiring material to the wiring forming machine 1. As shown in FIGS. 17A and 17B, the wiring forming machine 1 unidirectionally routes the wiring material 2 supplied from the wiring material supply device in accordance with the feed amount control signal output from the control unit 11. A wiring material transfer mechanism 21 for transferring the wiring material, a wiring material forming mechanism 23 for bending the wiring material 2 in accordance with a bending amount control signal output from the control unit 11, and a bending direction control signal output from the control unit 11. And a rotation mechanism 22 that changes the bending direction of the wiring member 2 according to the above. According to this conventional manufacturing apparatus, the wire forming machine 1 transfers the wiring material and places it in a predetermined direction according to the feed amount control signal, the bending amount control signal, and the bending direction control signal output from the control unit 11. By repeating a certain amount of bending, a wiring material formed into a required three-dimensional shape can be manufactured.

  By the way, in the above conventional manufacturing apparatus, a wiring material cut in advance to a predetermined length is supplied to a wiring forming machine. However, for continuous and efficient production, a long linear substrate is used. Is preferably continuously supplied along the axial direction, and after bending the tip portion of the linear base material, the tip portion is preferably cut and separated from the linear base material.

  In this regard, in the above-described conventional manufacturing apparatus, the bending direction of the wiring material is changed by the rotation of the wiring material forming mechanism located on the most downstream side in the manufacturing process, so that the tip of the bent wiring material is the wiring material forming mechanism. The direction of feeding from the plate also changes corresponding to the bending direction. For this reason, in the conventional manufacturing apparatus described above, when a cutting mechanism for cutting the wiring material is to be arranged downstream of the wiring material forming mechanism, the wiring material sent out in an arbitrary bending direction by the cutting mechanism is used. It was necessary to have a configuration capable of cutting. However, it has been difficult to realize a configuration that can accurately cut the wiring material fed in an arbitrary bending direction.

  This invention is made | formed in view of the situation mentioned above, The objective is to provide the manufacturing apparatus of the linear member which can manufacture a high quality linear member.

In order to achieve the above-described object, the linear member control device according to the present invention is characterized by the following points.
(1) A metal and long linear base material supplied along the axial direction is subjected to a three-dimensional bending process on the tip portion of the linear base material, and then the tip portion is moved to the line. A linear member manufacturing apparatus for manufacturing a linear member having a predetermined three-dimensional bending shape by cutting and separating from a linear substrate,
A control unit;
A holding part for holding the linear base material, and the holding part moves in accordance with a feed amount control signal from the control part in a state of holding the linear base material, thereby A transfer mechanism for transferring to one side in the axial direction;
A bending mechanism portion disposed on the one side of the transfer mechanism portion and bending the tip portion of the linear base material in a predetermined bending direction by a bending amount based on a bending amount control signal from the control unit; ,
A cutting unit that is disposed on the one side of the bending mechanism unit and that cuts and separates the tip portion bent into the three-dimensional bending shape from the linear base material based on a cutting signal from the control unit When,
With
The transfer mechanism unit rotates the linear substrate around the axial direction by rotating in accordance with a rotation control signal from the control unit in a state where the clamping unit clamps the linear substrate, thereby An apparatus for manufacturing a linear member, wherein a bending direction of the bending mechanism section with respect to the linear base material is changed.

According to the manufacturing apparatus of the linear member of (1) above, by the rotation of the transfer mechanism unit arranged upstream of the bending mechanism unit and the cutting unit (that is, the other side opposite to the one side). Since the bending direction of the linear base material is changed, even if the bending direction is changed, the direction in which the tip of the bent linear base material is sent out from the bending mechanism part is always the predetermined direction. Bending direction and constant. For this reason, according to the manufacturing apparatus of said (1), since the front-end | tip part of a linear base material can be cut | disconnected at the same position every time, the said front-end | tip part can be cut | disconnected with high precision and can be isolate | separated by a cutting part. As a result, according to the manufacturing apparatus of (1), a high-quality linear member can be manufactured.
Moreover, in the said conventional manufacturing apparatus, as shown in FIG.17 (b), the wiring material (linear base material) is conveyed, being pressed with the electric wire feed rollers 12b and 12c with which the wiring material transfer mechanism 21 is provided. . When the linear base material is transferred by pressing between the rotating rollers as described above, the feed amount may become unstable due to slippage between the roller and the linear base material. For this reason, it is difficult to manufacture a high-quality linear member with a conventional manufacturing apparatus.
On the other hand, in the linear member manufacturing apparatus of (1), the transfer mechanism moves with respect to the fixed bending mechanism in accordance with the feed amount control signal while holding the linear substrate. Thus, according to the manufacturing apparatus of said (1), since a transfer mechanism part moves in the state which fixed the linear base material, the feed amount of a linear base material can be controlled accurately. As a result, according to the manufacturing apparatus of (1), a high-quality linear member can be manufactured.
Further, in the above-described conventional manufacturing apparatus, depending on the strength of pressing by the wire feed rollers 12b and 12c shown in FIG. May not be good.
On the other hand, in the apparatus for manufacturing a linear member of (1), the bending direction of the linear base material is changed by rotating the transfer mechanism section with the linear base material sandwiched therebetween. The bending direction of the substrate can be changed with high accuracy. As a result, according to the manufacturing apparatus of (1), a high-quality linear member can be manufactured.

(2) The manufacturing apparatus of (1),
After the linear base material is cut by the cutting unit, the transfer mechanism unit rotates according to a return signal from the control unit in a state where the linear base material is sandwiched by the clamping unit, thereby It returns to the initial angle before performing the three-dimensional bending process on the tip portion of the material, and then, before the linear substrate is transferred in a state where the holding of the linear substrate by the clamping portion is released. Move to position.

When the conventional manufacturing apparatus is employed in a configuration for manufacturing a wiring material (linear member) having a predetermined length by continuously supplying a long linear base material along the axial direction, In the manufacturing apparatus, the rotating mechanism 22 that changes the bending direction of the wiring material by the rotation always holds the wiring material, so that twists are accumulated in the linear base material during the manufacturing process. If the twist is accumulated, the influence may appear on the manufactured linear member.
On the other hand, according to the manufacturing apparatus for a linear member of (2) above, after the linear base material is cut by the cutting portion, the transfer mechanism portion is in a sandwiched state and before bending the tip portion. After returning to the initial angle, the holding of the linear base material by the holding portion is released, and then it returns to the position before transfer. Thereby, since the twist of a linear base material is reset for every manufacturing cycle, twist is hard to accumulate | store in a linear base material. As a result, according to the manufacturing apparatus of (2), a high-quality linear member can be manufactured stably.

(3) The manufacturing apparatus according to (1) or (2),
A linear mechanism for removing bending wrinkles of the linear substrate supplied from a reel unit that winds and accommodates the linear substrate;
The linear base material from which bending wrinkles are removed by the linear mechanism portion is supplied to the transfer mechanism portion.

In order to supply the linear base material continuously and efficiently, it is preferable to provide a reel unit for winding and storing the linear base material. However, in this case, there is a possibility that bending wrinkles remain on the linear base material due to the winding at the reel portion. If bending wrinkles remain, the influence may appear on the manufactured linear member.
On the other hand, according to the manufacturing apparatus of the linear member of said (3), the linear base material from which the bending wrinkle was removed in the linear mechanism part can be supplied to a transfer mechanism part. As a result, according to the manufacturing apparatus of (3), a high-quality linear member can be manufactured stably.

(4) The manufacturing apparatus according to (3),
The linear mechanism portion has a first linear portion for removing bending wrinkles in a first direction orthogonal to the axial direction of the linear base material, and the axial direction and the first direction of the linear base material. And a second straight portion for removing bending wrinkles in the second direction orthogonal to each other.

  According to the linear member manufacturing apparatus of (4) above, the first linear portion and the second linear portion are orthogonal to the axial direction of the linear base material and are orthogonal to each other in the first direction and the second direction. Since the bending folds are removed, the bending folds can be removed more reliably. As a result, according to the manufacturing apparatus of (4), a high-quality linear member can be manufactured more stably.

  ADVANTAGE OF THE INVENTION According to this invention, the manufacturing apparatus of the linear member which can manufacture a high quality linear member can be provided.

  Hereinafter, an example of an embodiment of a linear member manufacturing apparatus according to the present invention will be described with reference to FIGS. The manufacturing apparatus according to the embodiment is roughly three-dimensional at the tip of the linear substrate with respect to a metal and long linear substrate that is continuously supplied along the axial direction. After the bending process, the tip portion is cut and separated from the linear base material, thereby producing a linear member having a predetermined three-dimensional bent shape. That is, in the manufacturing apparatus of the embodiment, a three-dimensional bending process is performed on the tip portion of the linear base material while feeding the linear base material to one side in the axial direction. Below, the said one side which is a feed direction is made into downstream, and the other side in a feed direction is demonstrated as an upstream.

  First, an example of a linear member manufactured by the manufacturing apparatus according to the embodiment will be described with reference to FIG. FIG. 1 is a perspective view showing a linear member 31 manufactured by the manufacturing apparatus according to the embodiment.

  As shown in FIG. 1, the linear member 31 has a predetermined three-dimensional bent shape. The linear member 31 is made of metal, and is formed of, for example, copper or aluminum that is a conductive metal. As for the linear member 31, the front-end | tip 32 is located in a downstream in a manufacturing process, and the rear end 33 is located in an upstream. The linear member 31 is cut | disconnected from the linear base material 100 in the rear end 33 by the cutting part 91 mentioned later. In this embodiment, the linear member 31 has three side portions 34, 36, and 38, and bent portions 35 and 37 that are positioned between these side portions. As shown in FIG. 1, the three side portions 34, 36, and 38 are formed so that the lengths thereof are L1, L2, and L3. In addition, the example of the three-dimensional bending shape of the linear member 31 shown in FIG. 1 is an example, and if the shape of the linear member 31 is a three-dimensional bending shape having a plurality of sides and bending portions, the example of FIG. Not limited to. In this specification, the three-dimensional bent shape is a bent shape that is bent not only in the first direction (for example, the vertical direction) but also in the second direction (for example, the horizontal direction) orthogonal to the first direction. Say.

  Then, with reference to FIGS. 2-7, the structure of the manufacturing apparatus which concerns on embodiment is demonstrated. 2 is a perspective view showing a manufacturing apparatus 41 according to the embodiment, FIG. 3 is a block diagram showing a connection state of each part in the manufacturing apparatus, FIG. 4 is a perspective view showing a linear mechanism portion 51, and FIG. 61, a perspective view showing the transfer mechanism portion 71, the bending mechanism portion 81, and the cutting portion 91, FIG. 5 (b) is a longitudinal sectional view of FIG. 5 (a), and FIG. 6 is a perspective view showing the bending mechanism portion 81. 7 is a perspective view showing the bending mechanism portion 81 and the cutting portion 91. In the following description, the upper, lower, front, rear, left and right directions are defined as indicated by arrows in each figure. These directions do not limit the arrangement of each part, and the arrangement of each part in the embodiment can be appropriately changed within the technical scope of the present invention.

  2, the manufacturing apparatus 41 includes a control unit 131 (see FIG. 3), a reel unit 121, a linear mechanism unit 51, a guide unit 61, a transfer mechanism unit 71, a bending mechanism unit 81, and a cutting unit 91. Is provided. The control unit 131 is a microcomputer, for example, and is connected to each of the reel unit 121, the linear mechanism unit 51, the guide unit 61, the transfer mechanism unit 71, the bending mechanism unit 81, and the cutting unit 91 as shown in FIG. And controls the operation of each of these parts. The linear mechanism unit 51, the guide unit 61, the transfer mechanism unit 71, the bending mechanism unit 81, and the cutting unit 91 are fixed to the frame 111, and the linear mechanism unit 51 is located below the flat plate 113 fixed to the frame 111. The guide unit 61, the transfer mechanism unit 71, the bending mechanism unit 81, and the cutting unit 91 are disposed on the upper side of the flat plate 113 and fixed to the flat plate 113.

  As shown in FIG. 2, the reel unit 121 is formed in a cylindrical shape and accommodates a long linear substrate 100 that is a material of the linear member 31 by winding it. The reel unit 121 rotates according to an instruction from the control unit 131 by power of a power unit (not shown). Thereby, the linear base material 100 is continuously supplied downstream along the axial direction. By accommodating the linear base material 100 in the cylindrical reel portion 121 in this way, it is possible to save the space of the equipment.

  As shown in FIG. 4, the straight mechanism 51 includes a first straight part 53, a second straight part 55, and a tension part 58 as main components. The linear mechanism unit 51 is used to remove bending wrinkles of the linear base material 100 supplied from the reel unit 121. That is, in order to supply the linear base material 100 continuously and efficiently, the linear base material 100 is preferably wound and accommodated by the reel unit 121. However, in this case, bending wrinkles may remain on the linear base material 100 due to being accommodated in the reel portion 121. If bending wrinkles remain, the influence may appear on the linear member 31 after manufacture. On the other hand, in this embodiment, the linear base material 100 from which bending wrinkles are removed by the linear mechanism unit 51 can be supplied to the downstream transfer mechanism unit 71.

  The first straight portion 53 is a mechanism for removing bending wrinkles in a first direction (that is, the vertical direction) orthogonal to the axial direction (that is, the front-rear direction) of the linear base material 100. The first linear portion 53 has a plurality of (eight in FIG. 4) rollers 54 arranged in two rows of the upper stage and the lower stage, and the linear base material 100 sent from the reel part 121 The roller 54 is pressed in the vertical direction to remove the bending wrinkles in the vertical direction.

  The second straight portion 55 is bent in the second direction (namely, left-right direction) perpendicular to the axial direction (namely, front-back direction) and the first direction (namely, vertical direction) of the linear substrate 100. It is a mechanism for removing. The second straight portion 55 has a plurality of (eight in FIG. 4) rollers 56 arranged in two rows of the left and right rows, and the linear base after passing through the first straight portion 53. The material 100 is pressed by the roller 56 in the left-right direction to remove bending wrinkles in the left-right direction.

  The tension part 58 is a member for pulling and conveying the linear base material 100 in the linear mechanism part 51. The tension unit 58 is controlled by the control unit 131 between the first position shown in FIG. 4 and the second position on the rear side (in other words, the downstream side) from the first position by the power of the power unit 59. It is configured to be able to reciprocate according to the instructions. Further, the tension part 58 is configured to be able to chuck the linear substrate 100 by a chuck part (not shown) by the power of the power part 57. Then, after the linear portion 100 is chucked by the chuck portion at the first position, the pulling portion 58 moves while pulling the linear substrate 100 to the second position, and then the chuck of the linear substrate 100 is moved. release. In this way, the tension unit 58 sequentially conveys the linear base material 100. When the linear base material 100 is pressed by the first straight part 53 and the second straight part 55 during the conveyance, the bending wrinkles of the linear base material 100 are removed as described above.

  The guide part 61 is a mechanism for guiding the linear substrate 100 sent from the linear mechanism part 51 side. As shown in FIGS. 5A and 5B, the guide portion 61 is configured such that the linear base material 100 can be chucked by the chuck portion 63 by the power of the power portion 62. The guide unit 61 chucks the linear substrate 100 and releases it according to instructions from the control unit 131.

  As shown in FIGS. 5 (a) and 5 (b), the transfer mechanism unit 71 includes a sandwiching unit 72, a base unit 76, and a pedestal 77 as main components. A transfer function of transferring the linear substrate 100 to the downstream side, and a bending direction changing function of twisting the linear substrate 100 around the axial direction to change a bending direction by a bending mechanism portion 81 described later. Have.

  As shown in FIGS. 5A and 5B, the sandwiching portion 72 is configured such that the linear base material 100 can be chucked by the chuck portion 73 by the power of the power portion 73 a. Further, the sandwiching portion 72 is configured to be rotatable in the left-right direction with respect to the base portion 76 according to the rotation of the belt 75 driven by the power of the power portion 74 (see FIGS. 10 to 13 described later). The base 76 is configured to be slidable in the front-rear direction with respect to the pedestal 77 by the power of the power unit 78. The rotation of the clamping unit 72, the opening and closing of the chuck unit 73, and the sliding movement of the base unit 76 are performed according to instructions from the control unit 131.

  In the transfer mechanism 71 having the above-described configuration, the base 76 is in the state where the holding part 72 holds the linear base material 100, and the base 76 is located at the origin position shown in FIG. 5A according to the feed amount control signal from the control part 131. The linear substrate 100 is transferred to the downstream side (transfer function) by moving stepwise from the front to the front (that is, downstream side) to the final position shown in FIGS.

  Further, the transfer mechanism unit 71 rotates the linear substrate 100 in the axial direction by rotating in the left-right direction in accordance with the rotation control signal from the control unit 131 while the clamping unit 72 clamps the linear substrate 100. This changes the bending direction of the bending mechanism 81 with respect to the linear base material 100 (bending direction changing function). The transfer function and the bending direction changing function, that is, the forward movement of the clamping part 72 and the rotation in the left-right direction may be performed simultaneously or separately in time intervals. Also good. In the present embodiment, the sandwiching portion 72 is configured to be rotatable about 270 ° in the left-right direction with respect to the base portion 76.

  As shown in FIGS. 5 (a) and 5 (b), the bending mechanism portion 81 is disposed on the downstream side of the transfer mechanism portion 71, and only the bending amount based on the bending amount control signal from the control portion 131 is obtained. Bending is applied to the tip 101 of the linear substrate 100 in a predetermined bending direction (downward in the embodiment). As shown in FIG. 6, the bending mechanism portion 81 includes a roller 82, a movable roller 83, and a guide pin 84 that guides the linear substrate 100 sent from the transfer mechanism portion 71.

  The movable roller 83 revolves around the roller 82 as shown in FIG. In the present embodiment, the movable roller 83 can rotate around the roller 82 at a rotation angle of about 140 ° to 150 ° from the position shown by the solid line in FIG. 6 to the position shown by the broken line. The movable roller 83 has a bearing inside and is configured to be capable of rotating. Therefore, the movable roller 83 revolves while rotating around the roller 82. As described above, since the movable roller 83 rolls along the surface of the tip portion 101 of the linear base material 100 during bending, a frictional force does not act on the tip portion 101. For this reason, for example, it is possible to prevent a bending return from occurring due to a frictional force acting on the surface of the tip 101 in the process in which the movable roller 83 returns to the original position after bending. At the time of bending, the movable roller 83 revolves around the roller 82 by a bending amount based on a bending amount control signal from the control unit 131, thereby bending the distal end portion 101 at an arbitrary angle.

  The cutting portion 91 is disposed on the downstream side of the bending mechanism portion 81 as shown in FIGS. 5 (a) and 5 (b). The cutting portion 91 has a cutting blade 92, and the tip portion 101 after being bent into a three-dimensional bending shape based on a cutting signal from the control portion 131 is removed from the linear substrate 100 with the cutting blade 92. Cut and separate. A cover 93 in which a slit 94 is formed is disposed on the left and right sides of the cutting blade 92. The entire cutting unit 91 is configured to be movable between the standby position shown in FIG. 5A and the cutting position shown in FIG. 7, and normally waits at the standby position and disconnects at the time of cutting. Move to the position and cut the tip 101.

  Below, with reference to FIGS. 8-16, an example of the manufacturing process by the manufacturing apparatus 41 demonstrated above is demonstrated. 8 to 16 are perspective views showing a series of steps for manufacturing the linear member 31 shown in FIG. In the manufacturing process described below, the control unit 131 draws the linear base material 100 from the reel unit 121 by the linear mechanism unit 51 before each transfer step (first transfer step and second transfer step). A drawing step (in other words, a bending wrinkle removing step for removing the bending wrinkles of the linear base material 100 as described above) is appropriately executed. Description is omitted.

  The initial state is the state shown in FIG. In the initial state, the chuck of the guide portion 61 is released. In addition, the base 76 of the transfer mechanism 71 is positioned at the origin position. In this embodiment, the length of the protrusion part from the bending mechanism part 81 of the linear base material 100 in the said initial state is set to the length L1 of the side part 34 shown in FIG. Note that the length of the protruding portion in the initial state may be set shorter than the length L1 of the side portion 34. In this case, a transfer step of transferring the linear base material 100 to the downstream side until the length of the protruding portion becomes equal to the length of the side portion 34 may be further added before the following bending step. However, if it is set as in this embodiment, one transfer step can be omitted, so that the manufacturing speed can be improved.

  First, the control unit 131 outputs a bending amount control signal to the bending mechanism unit 81, and the bending mechanism unit 81 causes the leading end portion 101 of the linear base material 100 to have a predetermined bending direction as illustrated in FIG. 8. (In the embodiment, the downward direction.) Bending is performed by a predetermined first bending amount corresponding to the bending portion 35 (first bending step). Thereby, the part used as the bending part 35 shown in FIG. 1 is formed. At this time, as described above, the clamping unit 72 chucks the linear substrate 100 with the chuck unit 73. Hereinafter, the chuck is not released until a return step described later.

  Next, the control unit 131 outputs a feed amount control signal to the transfer mechanism unit 71, and as shown in FIG. 9, the base portion 76 of the transfer mechanism unit 71 is moved forward with respect to the base 77 by the length L <b> 2 of the side portion 36. The linear base material 100 is transferred to the downstream side by the length L2 (first transfer step).

  Next, the control unit 131 outputs a rotation control signal to the transfer mechanism unit 71, and rotates the clamping unit 72 of the transfer mechanism unit 71 90 ° to the right with respect to the base 76, as shown in FIG. As a result, as shown in FIG. 10, the linear base material 100 is twisted by 90 ° clockwise around the axial direction, and the bending direction of the bending mechanism portion 81 with respect to the linear base material 100 is changed.

  Next, the control unit 131 outputs a bending amount control signal to the bending mechanism unit 81, and the bending mechanism unit 81 causes the tip part 101 of the linear base material 100 to move downward as shown in FIG. 11. Then, bending is performed by a predetermined second bending amount corresponding to the bending portion 37 (second bending step). Thereby, the part used as the bending part 37 shown in FIG. 1 is formed.

  Next, the control unit 131 outputs a feed amount control signal to the transfer mechanism unit 71, and as shown in FIG. The length L1 and the length L1 of the side portion 34 are moved by a total length, and the linear base material 100 is transferred to the downstream side by the length (second transfer step). By this operation, the base 76 of the transfer mechanism 71 is positioned at the final position. Further, as described above, the linear base material 100 is transferred in the initial state as described above by transferring only the length L3 of the side portion 38 and the length L1 of the side portion 34 in the second transfer step. The length of the protruding portion from the bending mechanism portion 81 is equal to the length L1 of the side portion 34 shown in FIG.

  Next, the control unit 131 outputs a signal for moving the cutting unit 91 to the cutting unit 91, and moves the cutting unit 91 to the cutting position as shown in FIG.

  Next, the control unit 131 outputs a cutting signal to the cutting unit 91 and cuts and separates the tip portion 101 bent into a three-dimensional bent shape from the linear base material 100 with the cutting blade 92 (cutting step). . At this time, the cutting portion 91 cuts the tip portion 101 so that the length of the protruding portion from the bending mechanism portion 81 of the linear base material 100 becomes the length L1 of the side portion 34 shown in FIG. By this cutting step, the linear member 31 shown in FIG. 1 is obtained. Thereafter, the control unit 131 outputs a control signal to the cutting unit 91 to move the cutting unit 91 to the standby position as shown in FIG.

  Next, the control unit 131 outputs a return signal to the transfer mechanism unit 71 and holds it to an initial angle before three-dimensional bending is performed on the tip portion 101 of the linear base material 100 as shown in FIG. The part 72 is rotated. This initial angle is a rotation angle in the initial state shown in FIG. Specifically, as shown in FIG. 15, the control unit 131 rotates the sandwiching unit 72 90 degrees to the left from the state shown in FIG. 14. Thereby, as shown in FIG. 15, the transfer mechanism part 71 returns to the angle in an initial state.

  Next, the control unit 131 outputs a feed amount control signal to the transfer mechanism unit 71 and moves the base 76 of the transfer mechanism unit 71 rearward with respect to the pedestal 77 as shown in FIG. (Return step) At this time, the control unit 131 chucks the linear substrate 100 by the chuck unit 63 of the guide unit 61, and the return of the linear substrate 100 by the clamping unit 72 of the transfer mechanism unit 71 is released. Perform steps.

  As described above, the transfer mechanism 71 returns to the initial angle before the bending of the distal end portion 101 in the sandwiched state after the cutting of the linear base material 100 by the cutting unit 91, and thereafter the sandwiching unit 72 The holding of the linear base material 100 is released, and the linear base material 100 is moved to the origin position which is a position before the linear base material 100 is transferred. As a result, according to the manufacturing apparatus 41, the twist on the tip side of the linear base material 100 is reset for each manufacturing cycle, so that the twist is difficult to accumulate in the linear base material 100. Further, the guide portion 61 functions as a pressing portion that chucks and holds the upstream side of the transfer mechanism portion 71 of the linear base material 100 when the twist is removed.

  By sequentially executing the steps described above, one cycle of the manufacturing process of the linear member 31 is completed, the linear member 31 is manufactured, and the manufacturing apparatus 41 returns to the initial state.

  According to the manufacturing apparatus 41, since the bending direction of the linear base material 100 is changed by the rotation of the transfer mechanism unit 71 arranged on the upstream side of the bending mechanism unit 81 and the cutting unit 91, the bending direction is changed. Even in this case, the direction in which the tip 101 of the bent linear base material 100 is sent out from the bending mechanism 81 is always downward and constant. For this reason, according to the manufacturing apparatus 41, since the front-end | tip part 101 of the linear base material 100 can be cut | disconnected at the same position every time, the said front-end | tip part 101 can be cut | disconnected with high precision by the cutting part 91, and can be isolate | separated. As a result, according to the manufacturing apparatus 41, the high-quality linear member 31 can be manufactured.

  Further, in the manufacturing apparatus 41, the clamping unit 72 of the transfer mechanism unit 71 moves according to the feed amount control signal with the linear base material 100 being clamped with respect to the fixed bending mechanism unit 81. Thus, according to the manufacturing apparatus 41, since the transfer mechanism part 71 moves in the state which fixed the linear base material 100, the feed amount of the linear base material 100 can be controlled correctly. As a result, according to the manufacturing apparatus 41, the high-quality linear member 31 can be manufactured.

  Further, in the manufacturing apparatus 41, the bending direction of the linear substrate 100 is changed by rotating the clamping unit 72 of the transfer mechanism unit 71 while sandwiching the linear substrate 100. The bending direction can be changed with high accuracy. As a result, according to the manufacturing apparatus 41, the high-quality linear member 31 can be manufactured.

  Further, according to the manufacturing apparatus 41, after the linear base material 100 is cut by the cutting unit 91, the holding unit 72 of the transfer mechanism unit 71 remains in the holding state at an initial angle before bending the tip part 101. Then, the transfer mechanism 71 returns to the original position in a state where the holding of the linear base material 100 by the holding unit 72 is released. Thereby, since the twist of the linear base material 100 is reset for every manufacturing cycle, a twist is hard to accumulate | store in the linear base material 100. FIG. As a result, according to the manufacturing apparatus 41, the high-quality linear member 31 can be manufactured stably.

  In addition, according to the manufacturing apparatus 41, the first straight portion 53 and the second straight portion 55 are perpendicular to the axial direction of the linear base material 100 and are perpendicular to each other (that is, the vertical direction) and the first. Since bending folds in two directions (ie, left and right directions) are removed, bending folds can be more reliably removed. As a result, according to the manufacturing apparatus 41, the high-quality linear member 31 can be manufactured more stably.

  The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, although the case where the linear member 31 which has the two bending parts 35 and 37 was manufactured was demonstrated in the said embodiment, the number of bending parts and a bending angle can be set arbitrarily. Further, as shown in FIGS. 9 to 12, only the case where the clamping portion 72 of the transfer mechanism portion 71 is rotated 90 ° to the right with respect to the base portion 76 has been described, but depending on the shape of the linear member 31, Sometimes it rotates to the left. Further, the unit of the rotation angle of the sandwiching portion 72 is not limited to 90 °, and the bending angle can be set by further finely rotating.

(1) The manufacturing apparatus 41 has the tip of the linear base material 100 with respect to the metal and long linear base material 100 that is continuously supplied along the axial direction (in the embodiment, the front-rear direction). After the part 101 is subjected to a three-dimensional bending process, the tip part 101 is cut and separated from the linear base material 100, thereby producing a linear member 31 having a predetermined three-dimensional bent shape. This is a manufacturing apparatus for the linear member 31. The manufacturing apparatus 41 includes a control unit 131. The manufacturing apparatus 41 further includes a transfer mechanism unit 71. The transfer mechanism unit 71 includes a clamping unit 72 that clamps the linear substrate 100.

The transfer mechanism 71 rotates the linear substrate 100 around the axial direction by rotating according to a rotation control signal from the control unit 131 in a state where the clamping unit 72 clamps the linear substrate 100. As a result, the bending direction of the bending mechanism 81 with respect to the linear substrate 100 is changed.
(2) In the manufacturing apparatus 41, the transfer mechanism unit 71 is configured so that the control unit 131 keeps the linear base material 100 sandwiched by the clamping unit 72 after the cutting of the linear base material 100 by the cutting unit 91. By rotating in accordance with a return signal from the linear base material 100, the tip 101 of the linear base material 100 is returned to an initial angle before the three-dimensional bending process, and then the linear base by the clamping unit 72 is restored. In a state where the holding of the material 100 is released, the linear base material 100 is moved to a position before transfer (in the embodiment, the origin position).
(3) The manufacturing apparatus 41 further includes a linear mechanism unit 51 for removing bending wrinkles of the linear substrate 100 supplied from a reel unit 121 that winds and stores the linear substrate 100. Then, the linear base material 100 from which bending wrinkles have been removed by the linear mechanism portion 51 is supplied to the transfer mechanism portion 71.
