Description

Coil manufacturing device

The present invention relates to a coil manufacturing apparatus for winding a wire which is taken out from a delivery port to manufacture a coil.

Conventionally, as a chip coil for a small electronic device or the like, it is known to wind a wire around a winding main body portion having a flange portion at both end portions to form a coil, and to fix the wire of the coil end portion. It is formed on the electrode of the flange portion. As an apparatus for manufacturing such a chip coil, there is known a device including: a wire feeding device that feeds a wire from a delivery outlet at a fixed tension; and a clamp device that clamps a wire end portion that is fed out from a delivery outlet; and a roll The jig is taken, the core is supported and rotated together with the core, and the wire fed from the delivery port is taken up to the rotating core (for example, refer to JP2007-266578A).

In the coil manufacturing apparatus, first, the winding jig is clamped, and then the winding jig is rotated together with the jig device that clamps the end portion of the wire, and the wire fed from the outlet is wound around the core. Winding. Then, after the winding is completed, the wire of the coil end portion is welded to the electrode formed on the flange portion to be fixed by wiring.

Therefore, the conventional coil manufacturing is constituted by clamping a core to a winding jig, winding, and wiring. For a relatively small chip coil, the following operation is performed, that is, preparing a plurality of coils Fixing the tool and moving it, during the winding of the core held by a winding fixture, the other winding fixtures are clamped to the core, and then the core of the winding is finished. With the wiring work, the number of coils produced per unit time can be increased by performing each operation at the same time.

Therefore, in the coil manufacturing in which the core is sandwiched between the winding jig, the winding, and the wiring, it is necessary to cut the wire which is fed out from the delivery port and wound on the core at one end of the winding, and In this state, the winding jig is transferred to the next wiring step together with the core. In this case, there is proposed a wire cutting scheme in which even if the jaw device that can cut the wire by electric or fluid pressure is three-dimensionally moved by the three-axis moving mechanism, the wire is clamped to one of the jaw devices. The wire is cut between the teeth, and the pair of cutting teeth are closed to each other, thereby cutting the wire (for example, refer to JP2012-80037A).

However, the wire cutting device in the conventional coil manufacturing apparatus moves the jaw device by the three-axis moving mechanism. Therefore, there is a tendency that the three-axis moving mechanism is relatively large and the overall size of the apparatus is increased.

Further, if the wire extending from the core to the delivery port is cut after the winding, the coil wound on the core is loosened by the elasticity of the wire, and the wire is loosened from the core. Therefore, in the apparatus for winding the winding fixture and winding and wiring at the respective positions, it is necessary to prevent the wire cut after the winding from being loosened from the core.

An object of the present invention is to provide a coil manufacturing apparatus which can cut a wire of a winding end of a coil without squeezing the apparatus, and hold the coil before wiring is performed. Both the winding start end and the winding end wire are prevented, so that the wound wire is prevented from being loosened from the core.

According to an aspect of the present invention, there is provided a coil manufacturing apparatus comprising: a delivery port for feeding a wire, a winding jig for winding a wire fed from the delivery port, and an end portion of the wire that is fed from the delivery port. a clamp device; and a substrate that is attached to the winding fixture with a main surface facing the circumference of the winding fixture; and a first holder that sandwiches the wire and the substrate together a side portion; a second holder that sandwiches the wire and the other side of the substrate; a cutter member that is disposed facing the other main surface of the substrate and supported to be opposite to the above The substrate is rotatably; the pressing means applies pressure to the cutting blade that rotates the cutter member to the cutter member from a side of the substrate; the delivery port moving mechanism causes the outlet to be three Moving in the axial direction to insert the wire extending from the winding fixture to the delivery port, and inserting the wire between the side of the substrate and the first holder, and the cutting from a side of the substrate Knife and upper Between one side of the substrate; a storage line moving mechanism that moves the clamp device in a triaxial direction to extend the wire extending from the winding fixture to the clamp device to the other side of the substrate And a member rotating means for rotating the cutter member to cut the wire inserted between the cutting blade and a side portion of the substrate.

Further, one end of the coil spring 60 is attached to the clamp device 53, and the other end of the coil spring 60 is fixed to the moving member 61. The moving member 61 is screwed to the male screw 62a of the tension adjusting screw 62, and the position of the moving member 61 is adjusted by rotating the male screw 62a.

Further, the coil spring 60 is pressed in a direction to move the clamp device 53 away from the winding jig 14. The storage moving mechanism 54 (Fig. 1) moves the moving plate 58 together with the clamp device 53 in the three-axis direction.

As shown in FIG. 1, the storage line moving mechanism 54 has the same structure as the above-described delivery port moving mechanism 33, and is configured by a combination of X-axis, Y-axis, and Z-axis direction expansion/contraction actuators 55 to 57.

A casing 56d of the Y-axis direction expansion and contraction actuator 56 that moves the moving plate 58 in the Y-axis direction is attached to the moving plate 58 provided with a plurality of clamp devices 53.

The follower 55c of the telescopic actuator 55 is moved in the X-axis direction.

Further, the outer casing 55d of the X-axis direction expansion and contraction actuator 55 extending in the X-axis direction is fixed to the pedestal 13.

Each of the servo motors 55a to 57a of each of the telescopic actuators 55 to 57 is connected to a controller (not shown) that controls the driving of the actuators 55 to 57.

The operation of each of the servo motors 55a to 57a, the ball screws 55b to 57b, and the followers 55c to 57c is the same as that of the delivery port moving mechanism 33, and thus the description thereof will be omitted.

Further, as shown in FIG. 4, the coil manufacturing apparatus 10 includes a clamp cutter 70 that can hold and cut the end portion of the wire 12 wound around the core 11 supported by the winding jig 14. The clamp cutting tool 70 is attached to the main body portion 20 of the winding jig 14 .

As shown in FIGS. 5-8, the clamp cutter 70 has a base plate 71 that is mounted around the take-up jig 14 with a main surface facing the take-up jig 14; the first clamp 72 And clamping the side of the wire 12 and the substrate 71 together; the second holder 73, which sandwiches the other side of the wire 12 and the substrate 71; the cutter member 74, which is different from the substrate 71 a main facing arrangement, and pivotally supported on the substrate 71; a mounting member 76 interposed between the substrate 71 and the take-up jig 14 and pivoting the first and second holders 72, 73 and The cutter member 74 and the presser 77 sandwich the substrate 71, the first holder 72, the second holder 73, and the cutter member 74 and the mounting member 76.

As shown in FIG. 5, the mounting member 76 is sequentially formed with a thin portion 76a that is in contact with the base end of one of the main faces of the substrate 71, and a middle wall portion 76b that is formed to be used for holding the cutting device. A hole 76d that is inserted into the main body portion 20 of the winding jig 14 and into which the screw 78 is inserted, and a thick portion 76c that is formed with a hole 76e or a groove 76f for accommodating the springs 79 and 80 to be described later. It is provided in the thin portion 76a to One of the first and second clamps 72, 73 pivotally supports the pivot pins 76g, 76h.

The substrate 71 has a rectangular flat plate, and notches 71a and 71b for avoiding interference with one of the mounting members 76 against the pivot pins 76g and 76h are formed on both sides of the proximal end side.

The first holder 72 and the second holder 73 are formed by processing the flat plates, respectively, and have a shape that is symmetrical to each other. The first holder 72 and the second holder 73 are respectively formed with bulging portions 72a and 73a accommodated in the notches 71a and 71b of the substrate 71. Inserting holes 72b and 73b into which the pivot pins 76g and 76h are fitted are formed in the bulging portions 72a and 73a, respectively. Further, the first holder 72 and the second holder 73 are formed with nip portions 72c and 73c on the same side as the bulging portions 72a and 73a, and are formed so as to sandwich the wire 12 and the substrate together. The shape of the side of the front end of 71. Further, protrusions 72d and 73d are formed on the proximal end sides of the first holder 72 and the second holder 73, respectively, and are protruded outward from both sides of the attachment 76 in a state of being attached to the attachment 76. Projecting portions 72e and 73e are formed on the protruding portions 72d and 73d, respectively, and the coil springs 79 are supported in a state where the first holder 72 and the second holder 73 are opposed to each other.

A coil spring 79 whose both ends are supported by the projections 72e, 73e is inserted into the proximal end sides of the first and second holders 72, 73. The coil spring 79 is pressed to expand the base ends of the first and second holders 72, 73, and the nip portions 72c, 73c formed at the front ends of the first and second holders 72, 73 are pressed against Both sides of the front end of the substrate 71. Therefore, when the wire member 12 enters between the sandwiching portions 72c and 73c and the both side portions of the front end of the substrate 71, the wire member 12 is sandwiched by the sandwiching portions 72c and 73c and both side portions of the front end of the substrate 71. Further, in order to facilitate the entry of the wire member 12, inclined surfaces 72f and 73f are formed on the edges of the faces of the sandwiching portions 72c and 73c facing the substrate 71, respectively.

The cutter member 74 is formed into a crank-shaped flat plate, and is formed with a pivot hole 74b for entering the pivot pin 76g pivotally supporting the second clamp 73 at the central straight portion 74a. central The straight portion 74a is provided to traverse the first and second holders 72, 73 along the equal wall portion 76b of the mounting member 76. At one end of the central straight portion 74a, a cutting blade 74c that extends so as to overlap with the sandwiching portion 72c of the first holder 72 is formed. Further, at the other end portion of the central straight portion 74a, an operation portion 74d extending so as to overlap with the protruding portion 73d of the second holder 73 is formed. In a state where the cutter member 74 is attached to the mounting tool 76, the operation portion 74d is formed to be displaced away from the mounting member 76 from the protruding portion 73d of the second holder 73.

As shown in FIG. 6, a coil spring 80 is inserted between the end of the operation portion 74d and the mounting tool 76. The coil spring 80 is pressed so that the operation portion 74d is separated from the mounting tool 76, and the cutter member 74 is rotated about the pivot pin 76g so that the cutter blade 74c is away from the side portion of the front end of the substrate 71. When the operation portion 74d is brought close to the attachment 76 against the pressing force of the coil spring 80, the gap between the cutter blade 74c and the side portion of the front end of the substrate 71 disappears as indicated by the single-dot chain line. Therefore, when the wire member 12 is held by the side portion of the front end of the substrate 71 and the first holder 72, the clamped wire 12 is cut by the cutter blade 74c.

As shown in FIG. 5, the presser 77 is configured to sandwich the first and second holders 72, 73 pivotally supported by the pivot pins 76g, 76h and the cutter member 74 between the presser 77 and the mounting member 76 to prevent The self-supporting pins 76g and 76h are detached from each other. The presser 77 is formed with a pin hole 77a through which the pivotal second holder 73 and the pivot pin 76g of the cutter member 74 can be inserted, and the presser 77 and the mounting tool 76 are mounted together on the winding jig. The screw 78 of the 14 screw is inserted through the screw hole 77b.

As shown in FIGS. 5 to 8, the male screw inserted into the screw hole 77b of the presser 77 and the screw 78 of the mounting member 76 is screwed to the main body portion 20 formed in the winding jig 14. The female thread shown in the figure is used to attach the clamp cutting tool 70 to the winding jig 14 . In a state where the grip cutting tool 70 is attached to the winding jig 14, the front end of the substrate 71 holding the cutting tool 70 is relatively convex. The front end edge of the main body portion 20 provided with the jig 21 is protruded. Further, the sandwiching portions 72c and 73c of the first and second holders 73 that abut against both side portions of the substrate 71 protrude from the front edge of the main body portion 20. Therefore, the wire 12 extending from the core 11 held by the jig 21 can be sandwiched by the side portions of the substrate 71 and the first and second holders 72, 73.

Next, the operation of the coil manufacturing apparatus 10 will be described.

In the coil manufacturing apparatus 10, first, a clamping means (not shown) disposed in the X-axis direction is placed, and the core 11 is held by the winding jig 14 and the winding jig 14 holding the core 11 is placed. Move to the winding method. Next, the winding is carried out on the core 11 held by the winding jig 14 by the winding means. The winding jig 14 holding the wound core 11 is moved to a wiring means (not shown), and wiring is performed in the wiring means.

The core 11 is held by the winding jig 14 by means of a clamping means (not shown), and the rod of the air cylinder (not shown) that faces the operating lever 26 of the winding jig 14 is placed. Specifically, first, the rod of the air cylinder is protruded upward, and the operation lever 26 is raised, and the fixed side sandwiching member 21a of the enlarged jig 21 is spaced apart from the upper side of the movable side sandwiching member 21b. Next, the flange portion 11a of one of the cores 11 is horizontally placed on the notch portion 21c of the fixed-side holding member 21a. Thereafter, the lever of the air cylinder is immersed to lower the operating lever 26, and the distance between the fixed-side holding member 21a and the movable-side holding member 21b which are higher than the pivot point is reduced. Thereby, the flange portion 11a which is horizontally placed on the notch portion 21c is sandwiched by the fixed-side holding member 21a and the movable-side holding member 21b.

Next, the plurality of winding jigs 14 holding the core 11 in this manner are moved to the winding means. The movement of the winding jig 14 is performed by rotating the ball screw 29 shown in FIGS. 1 to 3 by a motor (not shown). Since the ball screw 29 is screwed to the movable table 18, when the ball screw 29 is rotated, the movable table 18 and the base 16 and the plurality of winding jigs provided on the base 16 are mounted. 14 moves along the X-axis direction, and the self-clamping means moves to the winding means.

In the winding means, winding is performed on the core 11. Here, a case where the α-coil coil 17 is formed by winding will be described. In the winding of the core 11 of the winding means, the following steps are performed: a wire drawing step of holding the wire 12 sent from the delivery port 31 of the wire feeding machine and pulling out a predetermined length; and a winding step to make the winding fixture 14 is rotated, and the drawn wire 12 is wound around the core 11 held by the jig 21; in the α-coil forming step, the wire 12 is fed from the delivery port 31 by rotating the delivery port 31 and the core 11 in the same direction. Around the core 11, an alpha coil 17 is formed; the wire clamping step is such that the wires 12a, 12b at both ends of the alpha coil 17 are held by the substrate 71 and the first and second clamps 72, 73; and the wire is cut In the breaking step, the wire 12b extending from the core 11 to the delivery port 31 is cut.

Hereinafter, each step of winding the core 11 will be described. Further, as described above, five winding jigs 14 are provided on each of the two bases 16, and winding is simultaneously performed on the core 11 held by the five winding jigs 14. Since the winding of the core 11 of each of the winding jigs 14 is the same operation, the winding of the core 11 of one winding jig 14 will be described below.

<Wire Pulling Step>

In the wire drawing step, the wire 12 fed from the delivery port 31 is held and pulled out by a predetermined length. The wire 12 is wound around the drum 45, and the wire 12 fed from the drum 45 is wired in such a manner as to be guided by the wire guide 46a at the front end of the tension bar 46, and penetrates the rotating member 39 from the wire guide 46a via the pulley 38b. The through hole 39a is inserted.

The wire 12 is a so-called square wire having a square shape. The wire 12 composed of a square wire is inserted into the delivery hole 31a of the delivery port 31 after passing through the insertion hole 39a.

As shown in the enlarged view of Fig. 1, the wire 12 inserted through the delivery hole 31a is at the end The state is inclined upwards. By bending the end portion obliquely upward, the wire member 12 is locked to the hole edge of the delivery hole 31a, and the wire member 12 is prevented from returning toward the tension device 42 side.

In the wire drawing step, the clamp device 53 is moved by the wire moving mechanism 54, and the wire 12 fed from the delivery port 31 and bent upward obliquely is held by the holding pieces 53a and 53b.

Thereafter, the clamp device 53 is moved again by the wire moving mechanism 54, and as shown in Fig. 11, the clamp device 53 is pulled away from the delivery port 31. Thereby, the wire 12 of a predetermined length is pulled out from the delivery port 31.

The predetermined length is the length of the wire 12 required for the coil winding of one of the formed alpha coils 17 (Fig. 14). The movement of the clamp device 53 is stopped at a stage where the length of the wire 12 pulled out from the delivery port 31 is substantially equal to the predetermined length, and the wire pulling-out step ends.

<Winding step and α-turn coil forming step>

Hereinafter, a case where the winding step and the α-turn coil forming step are simultaneously performed will be described.

In this step, the delivery port moving mechanism 33 shown in FIGS. 1 and 2 moves the rotating member 39 provided with the delivery port 31 toward the upper side of the jig 21 so that the center of rotation of the rotating member 39 coincides with the center of rotation of the jig 21. Then, the delivery port moving mechanism 33 lowers the rotary member 39 so that the delivery hole 31a of the delivery port 31 faces the winding main body portion 11c of the core 11 in a state where the rotation center of the rotary member 39 coincides with the rotation center of the jig 21 .

Next, as shown in FIG. 12, the clamp device 53 is moved by the wire moving mechanism 54 so that the wire 12 pulled out from the feed port 31 moves along the winding body portion 11c of the core 11.

Then, as shown in FIG. 13, the wire 12 which is rotated by the winding jig 14 is retracted to the core 11, and at the same time, the delivery opening 31 is rotated twice as fast as the winding of the jig 14. The wire 12 that is rotated in the same direction and sent out from the delivery port 31 is wound around the core 11 to form A-turn coil 17.

The rotation of the delivery port 31 is performed by rotating the rotating member 39 provided with the delivery port 31 by the motor 32 (FIG. 1). The delivery port 31 rotates around the circumference of the core 11. The rotation direction of the delivery port 31 is the same direction as the rotation direction of the jig 21, and is rotated at twice the rotation speed of the jig 21.

Thereby, the wire 12 newly fed from the delivery port 31 and the wire 12 which is retracted from the jig device 53 in the direction indicated by the solid arrow in FIG. 13 are simultaneously wound around the core 11. At this time, the wire 12 newly fed from the delivery port 31 is sent out along the other flange portion 11b of the core 11, and is biased toward the other flange portion 11b side and wound around the winding body portion 11c.

On the other hand, the rotation of the winding jig 14 is performed by a motor 23 attached to the pedestal 13 shown in FIG. The wire 12 pulled out by moving the clamp device 53 away from the jig 21 is rewinded to the core 11 held by the jig 21.

After the rewinding of the wire 12 is started, the wire moving mechanism 54 causes the jig device 53 to approach the jig 21 at a speed substantially equal to the speed at which the wire 12 is rewinded. As described above, since the clamp device 53 approaches the clamp 21 at an appropriate speed, the wire 12 can be prevented from being deflected during the rewinding of the wire 12 to cause the coil of one of the formed α-coil coils to swell.

Further, at this time, the coil spring 60 (FIG. 10) is pressed in a direction in which the clamp device 53 is moved away from the winding jig 14. Therefore, the error generated between the amount of the rewinding wire 12 and the amount of movement of the jig device 53 can be eliminated, so that the deflection of the wire 12 between the jig device 53 and the core 11 can be surely prevented. At this time, the wire 12 retracted from the jig device 53 is rewound to the winding main body portion 11c along the flange portion 11a of the core 11, and is wound around the flange portion 11a side and wound around the winding main body portion 11c.

Thereby, the wire 12 which is previously pulled out by the clamp device 53 is formed, that is, by the clamp The wire 12a wound at the winding start end of the core 11 and the wire 12b which is fed from the feed port 31 and wound at the winding end of the core 11 are located at the outermost circumference of the coil. 17 (Figure 13).

<Wire clamping step>

In the wire holding step, the wires 12a, 12b at both ends of the ? coil 17 are held by the clamp cutting tool 70.

First, the clamping of the wire 12a at the winding start end will be described. As shown in FIG. 14, the clamp device 53 is moved by the storage wire moving mechanism 54 to press the wire 12a extending from the clamp device 53 to the winding start end of the core 11 to the other side of the substrate 71. Between the two clamps 73. Thereby, the wire 12a at the winding start end is displaced downward from the upper portion on the other side of the substrate 71, and enters from the inclined surface 73f of the second holder 73 to the other side of the substrate 71 and the second clip. Hold between 73. Thereby, the wire 12a at the winding start end is sandwiched by the other side of the substrate 71 and the second holder 73.

In this case, since the substrate 71 and the second holder 73 are located obliquely downward from the α-coil coil 17, the end edge of the wire 12a at the winding start end is extended obliquely downward from the core 11 and held. .

Thereafter, the clamp device 53 is detached from the wire 12a at the winding start end, and the wire 12a at the winding start end is detached from the clamp device 53. Next, the clamp moving mechanism 54 moves the clamp device 53 to the standby position, and waits until the next wire cutting step.

Next, the clamping of the wire 12b at the winding end will be described. As shown in Fig. 14, the feed port 31 is moved by the feed opening moving mechanism 33 (Fig. 1) to press the wire 12b extending from the feed opening 31 to the winding end of the coil 17 to the side of the substrate 71. With the first folder Hold between 72. Thereby, the wire end 12b of the winding end is displaced downward from the upper portion on one side of the substrate 71, and enters from the inclined surface 72f of the first holder 72 to the side of the substrate 71 and the first holder 72. between. Thereby, the wire 12b of the winding end is sandwiched by the side of one of the substrates 71 and the first holder 72.

<Wire cutting step>

In the wire cutting step, the wire 12b extending from the core 11 to the winding end of the delivery port 31 is cut. The cutting of the wire is performed by means of member rotation. Here, the storage line moving mechanism 54 will also be described as a member rotation means.

Specifically, as shown in FIG. 15, the clamp device 53 is moved by the storage wire moving mechanism 54, and the holding pieces 53a and 53b of the clamp device 53 are brought into contact with the operation portion 74d of the cutter member 74. Next, the operation portion 74d is moved against the biasing force of the spring 80, and the cutter member 74 is rotated about the pivot pin 76g. As shown in Fig. 15, the cutter blade 74c is displaced by the rotation of the cutter member 74 as indicated by the dotted arrow. Therefore, the wire 12b extending from the core 11 to the winding end of the delivery port 31 is sandwiched between the cutter blade 74c and one side of the substrate 71 to be cut.

After the cutting, the wire 12b extending from the core 11 to the cutter member 74 is sandwiched between the side of one of the substrates 71 and the first holder 72.

In this case, since the delivery port 31 is located obliquely below the α-coil coil 17, the wire 12b after the cutting is pulled out obliquely upward from the delivery port 31. In addition, the wire 12b which is in a state of being pulled out from the delivery port 31 after being cut is the next time the wire 12b is wound around the core 11, and becomes the wire 12a of the winding start end pulled out by the jig apparatus 53.

Thereafter, the delivery port 31 is moved to the standby position by the delivery port moving mechanism 33. Here, after the cutting, as shown in an enlarged view of Fig. 1, the delivery hole 31a of the outlet 31 is pulled out. The end portion of the wire 12 is pulled out obliquely upward. Therefore, the wire 12 is locked to the edge of the hole of the delivery hole 31a, and is prevented from returning to the tension device 42 side until the next winding is performed.

Then, the α-coil coil 17 composed of the wire 12 wound around the core 11 in this manner is moved in the X-axis direction together with the core 11 and the winding jig 14 and transported to the wiring means. Here, the cutter member 74 that cuts the wire 12, the substrate 71 that holds the wire 12, the first holder 72, and the second holder 73 are disposed on the winding jig 14, so that the winding is taken up. With 14 and move along the X axis. Therefore, even if the wire member 12b of the winding end of the coil 17 is cut by the cutter member 74, the wire 12a, 12b of the winding start end and the winding end of the coil 17 can be maintained by the substrate 71 and the holder 72. And the state in which the substrate 71 is sandwiched by the holder 73.

As described above, in the coil manufacturing apparatus 10, both the winding start end and the winding end of the formed coil 17 are held by the wires 12a and 12b. Therefore, when the winding jig 14 is moved in order to perform the subsequent wiring, the wires 12a and 12b at the winding start end and the winding end can be held, so that the wire 12 that has been wound can be prevented from being loosened.

Next, after the winding jig 14 of one base 16 is transported to the wiring means, the other base 16 and the plurality of winding jigs 14 are moved together from the holding means and transported to the winding means. Next, the core 11 held by the plurality of winding fixtures 14 of the other base 16 is again wound. In this manner, the wiring operation of the plurality of coils of one base 16 is simultaneously performed with the winding of the plurality of cores 11 of the other base 16, and the number of coils 17 produced per unit time can be increased by simultaneously performing the respective operations.

Here, in the case where a so-called square wire having a square cross section is used as the wire member 12, if the feed port 31 is rotated when the wire 12 is wound in the α-turn coil forming step, the wire 12 is on the drum 45 and the delivery port 31. Reversed between. In order to eliminate the twist, it is preferred to cut off the winding end. After the end of the wire 12, the delivery port 31 is rotated together with the jig 21 in the opposite direction to the winding to eliminate the twist. The number of rotations is the same as the number of rotations when winding. Thereby, the next wire drawing step can be started again in a state where the twist is eliminated.

As described above, in the present embodiment, since the cutter member 74 is provided around the winding jig 14, the wire member 12 can be cut only by rotating the cutter member 74 by the member rotating means 54. Therefore, in the coil manufacturing apparatus 10, it is not necessary to cut the wire 12 by a conventionally required jaw device or a three-axis moving mechanism.

Further, the cutter member 74 that cuts the wire member 12 is a flat member that is provided around the winding jig 14 and is not a large member. Further, there is no need for an independent drive mechanism that operates the cutter member 74. Thereby, it is possible to form a smaller coil manufacturing apparatus 10 capable of cutting the wire 12b of the winding end of the formed coil 17 with a predetermined length.

Further, since the delivery port 31 is rotated in the same direction at a speed faster than the rotational speed of the winding jig 14, the wire 12 fed from the delivery port 31 and the wire 12 stored in the storage means 52 are taken up. The core 11 is held by the jig 21, so that the α-coil 17 which appears on the outer circumference of the coil together with the wires 12a and 12b of the winding start end and the winding end can be manufactured. In the case where such an α-turn coil 17 is formed, the wire 12b of the winding end of the formed coil 17 can also be cut. Further, since the wires 12a and 12b at the winding start end and the winding end can be held, the wire 12 after the winding can be prevented from being loosened.

Furthermore, in the above-described embodiment, the case where the delivery port 31 is rotated at a speed faster than the rotational speed of the jig 21 to manufacture the alpha-circle coil 17 has been described. However, the method of manufacturing the alpha coil 17 is not limited thereto, and instead of the delivery port 31, the clamp device 53 as the storage device 52 may be used to wind up the speed of the jig 14 by a rotating means (not shown). Fast speed toward the phase Rotating in the same direction to manufacture the α-coil coil 17 which appears on the outer circumference of the coil together with the wires 12a and 12b of the winding start end and the winding end. In this case, both ends of the coil can be held, and the wire 12b of the winding end of the coil can be cut by the cutter member 74.

Moreover, in the above-described embodiment, the delivery port moving mechanism 33 and the storage line moving mechanism 54 which are constituted by a combination of the X-axis, the Y-axis, and the Z-axis direction expansion/contraction actuator have been described. However, the configuration of the delivery port moving mechanism 33 and the storage line moving mechanism 54 is not limited thereto, and may be any form as long as the object can be moved in the three-axis direction.

Moreover, in the above embodiment, the case where a so-called square wire having a square cross section is used as the wire member 12 has been described. The wire 12 is not limited to a square wire, and the wire 12 may have a rectangular or polygonal shape in cross section, and may also be a so-called circular wire having a circular cross section.

Moreover, in the above-described embodiment, the case where the wire 12 is wound around the core 11 held by the jig 21 to form the α-coil coil 17 has been described. However, the method of forming the coil is not limited thereto, and the core 11 may be omitted, and the wire 12 may be directly wound around the winding jig 14 to form the coil 17. In this case, it is preferable to provide a winding core for winding the wire 12 on the winding jig 14 instead of the jig 21 for holding the core 11. The coil formed by winding the wire 12 around the core becomes a so-called hollow core coil composed only of the wire 12 without the core 11.

Moreover, in the above-described embodiment, the case where the two bases 16 are provided and each of the five winding jigs 14 is provided is described. However, the number of the base 16 and the winding jig 14 provided on the base 16 is not limited thereto, and three or more bases 16 may be provided, and six or more rolls may be provided on the single base 16. Take the fixture 14.

Moreover, in the above embodiment, the case where the winding step and the α-turn coil forming step are simultaneously performed has been described. That is, in the above embodiment, the winding jig 14 is rotated. The drawn wire 12 is wound around the core 11, and the delivery port 31 is rotated in the same direction by a rotation speed twice as fast as the rotation of the winding jig 14 and the wire 12 fed from the delivery port 31 is wound around the core 11. An alpha coil 17 is formed. However, instead of this, the alpha coil forming step may be performed after the winding step.

Specifically, the winding step is performed such that the wire 12 pulled out by the clamp device 53 is first rotated even if the winding jig 14 is rotated and the delivery port 31 is rotated in the same direction at the same rotational speed as the rotational speed of the winding jig 14 Winding around the core 11 forms a coil. Thereafter, the following alpha coil forming step is performed, and even if the rotation of the winding jig 14 is stopped and the rotation of the delivery port 31 is continued, the wire 12 fed from the delivery port 31 is wound around the core 11 for stopping rotation and a coil. Another coil is formed adjacently. Thus, the alpha coil 17 composed of both coils can be formed by performing the alpha coil forming step after the winding step.

Further, in the above embodiment, the case where the storage line moving mechanism 54 also serves as the member rotating means has been described. However, instead of this, as shown in FIG. 16, a member rotating means is also provided on the base 16 of the pivotal winding fixture 14. The member rotating means includes, for example, a fluid pressure cylinder 81 which is provided on the base 16 and which is caused by the fluid pressure to cause the exit rod 81a to exit.

The fluid pressure cylinder 81 shown in Fig. 16 is discharged by the supply of compressed air to cause the exit rod 81a to exit. A plurality of fluid pressure cylinders 81 are provided on the base 16 through the lifting cylinders 82 so that the winding rods 81a and the winding jig 14 face each other. The rod 82a of the lifting cylinder 82 faces upward, the body portion 82b is attached to the base 16, and the fluid pressure cylinder 81 is attached to the upper end of the rod 82a.

When the rod 82a of the lifting cylinder 82 is immersed in the main body portion 82b, the fluid pressure cylinder 81 is lowered to stand by at the standby position indicated by the broken line. Next, in the wire cutting step, the rod 82a of the lifting cylinder 82 is protruded upward, and the fluid pressure cylinder 81 is raised to press the fluid cylinder. The exit lever 81a of 81 is opposed to the operation portion 74d of the cutter member 74.

In this state, when the exit lever 81a of the fluid pressure cylinder 81 is protruded, the front end of the exit lever 81a comes into contact with the operation portion 74d, and if it is further protruded, the operation portion 74d moves against the biasing force of the spring 80, thereby causing the cutter to be moved. Member 74 is rotated. Even in the member rotating means configured as described above, the wire 12b extending from the core 11 to the winding end of the delivery port 31 can be cut by the cutter blade 74c.

Although the embodiment of the present invention has been described above, the above embodiment is only a part of the application example of the present invention, and the technical scope of the present invention is not limited to the specific configuration of the above embodiment.
