[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rod supply device, and is suitable for application to, for example, a wire rod supply device used in a coil winding device.

[0003]

2. Description of the Related Art Conventionally, in a coil winding device for forming a coil by winding a conductive wire, a predetermined amount of the conductive wire is fed out and grasped by a predetermined chuck to perform a winding operation. Method is used.

In such a coil winding machine, there is a wire rod feeding device for feeding a predetermined amount of conductive wire as shown in FIG. That is, in FIG. 14, reference numeral 1 denotes a wire rod supplying device as a whole, and a feed drive unit 4 is provided on a base 2 and a wire rod gripping unit 5 provided on the feed drive unit 4 is moved in the direction of arrow a or in the opposite direction. It is designed to be able to move back and forth.

The wire rod gripping portion 5 can hold the wire rod 10 by closing the gripping members 6A and 6B by the guide portion 8 in the directions of arrow b and arrow c, respectively. The wire rod 10 can be released by performing an opening operation in the opposite direction to b and the opposite direction to the arrow c.

A guide cylinder 12 is fixed on the base 2 by a supporting portion 11, and the tip end of the wire rod 10 is guided and supported by the guide cylinder 12, whereby the tip end of the wire rod is positioned. To be done.

When the wire rod feeding device 1 sends the wire rod to the device provided in the next stage, the control unit 14 first sets the wire rod in FIG.
As shown in FIG. 4, the wire rod 10 is pinched by the gripping members 6A and 6B from an initial state in which the wire rod gripping portion 5 is moved in the opposite direction to the arrow a by the feed driving portion 4.
The wire driving part 4 moves the wire gripping part 5 in the direction of arrow a (that is, in the direction in which it approaches the guide cylinder 12).

At this time, the wire rod 10 is sent out in the direction of the arrow a while its tip is guided by the guide cylinder 12. When the wire rod 10 is moved by the distance L1 by the wire rod gripping portion 5, the movement is stopped and the gripping members 6A and 6B open the wire rod 10. In this state, a device (not shown) provided in the next stage grips the tip of the wire rod 10 and performs the next process such as winding.

When the tip of the wire rod 10 is clamped by the next-stage device, the gripping members 6A and 6B release the wire rod 10, and the feed drive unit 4 moves the wire rod gripping unit 5 in the direction opposite to the arrow a. Move and return to the initial position. When the processing for winding the wire rod of the next-stage device is completed at this position, the gripping member 6A
6B again clamps the wire 10. In this manner, the wire rod feeding device 1 is configured to feed the wire rod 10 by the predetermined amount L1 while guiding the wire rod 10 by the guide cylinder 12.

[0010]

By the way, in the wire rod feeding device 1 having such a structure, as shown in FIG. 15 (A), the distance L2 from the guide cylinder 12 to the tip of the wire rod 10 is increased.
When the wire rod 10 is relatively small (hereinafter, referred to as a wire rod protrusion amount), the displacement amount D2 of the wire rod tip portion is small even if the wire rod 10 is bent, but as shown in FIG. When the protrusion amount L3 of the wire rod 10 is large, the wire rod 10 concerned
The amount of displacement D3 at the tip of the wire increases due to the bending that occurs in the wire.

Accordingly, by reducing the protrusion amount of the wire rod 10, the displacement amount of the tip end portion of the wire rod is reduced, and the positioning accuracy of the tip end portion of the wire rod is improved.
It is considered that the tip end portion of the wire can be reliably sandwiched by a device such as a winding machine provided in the next stage.

However, as shown in FIG. 16, the tip end of the wire rod 10 is fed into the operating region of the unit such as the winding machine 20 provided in the next stage of the wire rod feeding device 1, so that the guide cylinder is fed into this region. It is difficult to always arrange the body 12 close to each other, and as a result, there is a problem that the amount of protrusion of the wire rod 10 from the guide cylinder 12 must be increased.

Further, as shown in FIG. 17, the guide cylinder 12
The wire rod 10 sent out from is a part of a predetermined cutting device 2
The amount of protrusion L5 which 2 interferes with remains after the cutting, and therefore the amount of protrusion actually for the purpose of cutting is as shown in FIG. 17B. The added protrusion amount is L7, and there is a problem that the protrusion amount becomes large.

When the amount of protrusion becomes large as shown in FIG.
As shown in FIG. 5, the distance between the guide cylinder 12 fixed to the base 2 and the gripping members 6A and 6B is increased,
In this portion, the wire rod 11 is easily bent, and when the wire rod gripping portion 5 holding the wire rod 10 in this state is moved in the direction of the arrow a to send out the wire rod 10, the wire rod 10 of the guide tube body 12 at the entrance 12A side. Part of 10X bends and the wire 1
It becomes difficult to reliably send 0.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a wire rod feeding device capable of surely feeding the wire rod and improving the positioning accuracy of the tip portion of the fed wire rod. .

[0016]

In order to solve such a problem, according to the present invention, a wire rod feeding device for feeding a predetermined amount of wire rod from a guide member while holding the wire rod by a predetermined guide member. The guide member control means controls the movement of the guide member in the feed direction of the wire rod, and the feed amount of the wire rod and the movement amount of the guide member are separately controlled.

According to the present invention, the guide member moves in the same direction as the wire rod during the feeding operation of the wire rod,
Only when the wire is fed, the guide member moves into the operation area of the device provided in the next stage of the wire feeding device. At this time, by controlling the feed amount of the wire rod and the movement amount of the guide member separately, only the minimum necessary protrusion amount required to transfer the tip end portion of the wire rod to the device provided in the next stage The wire rod projects from the guide member.

Accordingly, the winding main shaft portion 47 grips the tip end portion of the wire rod 10 sent from the wire rod supply device 50 at the main shaft 47A, and then the spindle motor 45 causes the main shaft 47A to rotate about the main shaft 47A and the traverse motor. A coil formed by winding the wire rod 10 is formed by moving the wire rod 10 in the axial direction of the main shaft 47A by means of 46.

When the coil is formed, the coil is cut from the wire rod 10 by the wire rod cutting portion 48 provided in a part of the wire rod feeding device 50, and the winding main shaft portion 47 is cut by the coil transfer portion 49. And the coil insertion part 4
Transferred to No. 4. The coil insertion part 44 is a coil transfer part 49.
The coil received from the substrate table 3 of the substrate transfer unit.
It is mounted on the substrate 31 positioned on the substrate 7. Thus, as shown in FIG. 3, the coil 15 is mounted in the mounting hole 31A of the substrate 31.
Is inserted. When the mounting of the coil 15 on the board 31 is completed, the board transfer unit 36 (FIG. 1) transfers the board table 37 on which the board 31 is placed by the transfer conveyor 38.

The coil winding device 30 includes a plurality of winding units 4 having the same structure as the winding unit 40A as the winding unit 40.
0B, 40C, 40D, 40E and 40F, and the coil formed by each winding unit 40A to 40F can be mounted on the substrate 31.

(2) Structure of Wire Rod Feeding Device In FIG. 4 in which parts corresponding to those in FIG. 2 are denoted by the same reference numerals, the wire rod feeding device 50 has a wire rod gripping portion 54 on a straight road guide rail 52 fixed to a base member 51. Gripping portion slider 54A and wire rod guide portion 55 guide portion slider 55A
Are engaged so as to be vertically movable in the directions indicated by arrows d and e, respectively.

The gripper slider 54A includes a base member 51.
A drive actuator 57 as a drive means fixed to the
The output shaft 57A is engaged with and fixed to the output shaft 57A, and when the output shaft 57A moves up and down by driving the drive actuator 57, the output shaft 57A can move up and down accordingly. Incidentally, in this embodiment, the downward direction indicated by the arrow e is the forward direction for feeding the wire rod 10, and the upward direction indicated by the arrow d is the backward direction.

The base member 51 has a grip portion slider 54A.
The forward-side stopper 61 and the backward-side stopper 62 that limit the movement of the above are fixed. Therefore, the gripper slider 54A
Is advanced by the drive actuator 57 in the direction indicated by the arrow e, the lower surface of the projection 54C formed on the grip slider 54A abuts on the advance stopper 61, thereby advancing the grip slider 54A. Stops. On the other hand, when the grip slider 54A is retracted in the direction indicated by the arrow d, the upper surface of the protrusion 54C contacts the retractable stopper 62, and the retract operation of the grip slider 54A is stopped.

The grip slider 54A includes an opening / closing drive unit 54.
B is provided and the wire rod 10 interposed between the fertilizer members 6A and 6B is sandwiched by closing and holding the gripping members 6A and 6B in the directions of the arrows f and g by the opening / closing drive unit 54B. In addition, the wire rod 10 can be released by performing an opening operation in the opposite direction to the arrows f and g, respectively. Accordingly, the wire rod 10 is sandwiched by closing the gripping members 6A and 6B,
In this state, the grip portion slider 54A is moved in the forward direction by the drive actuator 57 to move the wire rod 1
You can send 0.

Here, a shaft member 65 is fitted and fixed at an upper portion thereof into a fitting hole 54D formed in the grip slider 54A so that the shaft member 65 can move forward and backward integrally with the grip slider 54A. . The shaft member 65 is loosely fitted in a loose fitting hole 55D formed in the guide slider 55A,
A retaining ring 67 is fixed to the lower end. Therefore, the guide portion slider 55A is restricted from moving in the forward direction by the retaining ring 67, and the retaining ring 67 and the grip portion slider 54A are restricted.
It is supported so that it can move forward and backward freely.

The shaft member 65 is provided with a spring 66 between the grip portion slider 54A and the guide portion slider 55A, whereby the guide portion slider 55A is always in contact with the retaining ring 67 by its own weight and the spring 66. It is biased in the (forward direction).

Accordingly, the shaft member 65, the spring 66 and the retaining ring 6
Reference numeral 7 constitutes an engaging means 68 for making the guide portion slider 55A operate in a dependent manner with respect to the grip portion slider 54A, whereby the guide portion slider 55A is driven by the drive actuator 5.
When the gripper slider 54A is advanced or retracted by 7, it is accordingly advanced or retracted. The guide cylinder 12 is supported and fixed to the guide slider 55A by a support 55B, and the tip of the wire 10 is inserted inside the cylinder of the guide cylinder 12. Accordingly, the tip end portion of the wire rod is guided and supported by the guide cylinder 12 and positioned. Incidentally, when the guide portion slider 55A moves forward or backward together with the grip portion slider 54A, the guide cylinder 12 and the wire rod 1
The relative position of 0 does not change.

An advance-side stopper 63 for restricting the movement of the guide slider 55A in the forward direction is fixed to the base member 51. Therefore, the guide slider 55A
Is moved in the forward direction indicated by arrow e in response to the movement of the grip slider 54A, the lower surface of the projection 55C formed on the guide slider 55A comes into contact with the forward stopper 63, so that the guide slider moves. The forward movement of 55A stops.

When the guide slider 55A is united with the grip slider 54A and moves forward in the direction of arrow e, the forward stopper 63 comes before the grip slider 54A comes into contact with the forward stopper 61 and stops. The guide portion slider 55A is fixed at a position where it stops.

That is, as shown in FIG. 5, the guide slider 55A is engaged with the engaging means 68 at the position where the grip slider 54A is in contact with the retractable stopper 62 (initial position).
The position of the retaining ring 67 in the forward direction (the direction of arrow e) is regulated by the spring 66 and the retaining ring 67, and the retaining ring 67 is held at a height corresponding to the fixed position of the retaining ring 67 with respect to the shaft member 65. At this time, the lower side surface of the protrusion 55C of the guide slider 55A is not in contact with the forward stopper 63, and the predetermined height position (L
12). In this state, the distance L11 between the lower side surface of the protrusion 54C of the grip slider 54A and the forward stopper 61 is equal to the distance L1 between the lower side surface of the protrusion 55C of the guide slider 55A and the forward stopper 63.
It is bigger than 2.

When the drive actuator 57 is driven to move the grip slider 54A in the forward direction at the initial position shown in FIG. 5, the guide slider 5 is moved as shown in FIG.
5A is subordinately operated by the engaging means 68,
It moves similarly in response to the gripper slider 54A. In this case, the relative position of the guide cylinder 12 and the wire rod 10 does not change, and the amount L25 of protrusion of the wire rod 10 from the guide cylinder body 12 is maintained.

In this way, the guide slider 55A moves forward integrally with the grip slider 54A, and the gap L12 formed between the guide slider 55A and the forward stopper 63 at the initial position (FIG. 5). 7, the lower side surface of the protrusion 55C of the guide slider 55A is moved to the forward side stopper before the lower side surface of the protrusion 54C of the grip slider 54A abuts the forward side stopper 61, as shown in FIG. Abut 63. In this state, a predetermined distance L21 remains between the lower side surface of the protrusion 54C of the grip slider 54A and the forward stop 61, and only the grip slider 54A can move forward by the additional movement distance L21. it can.

Therefore, when the drive actuator 57 is further driven from the state shown in FIG. 7 to move the grip slider 54A forward, the guide slider 55A regulated by the forward stopper 63 does not move forward but the grip portion. Slider 5
Only 4A moves forward against the biasing force of the spring 66. As a result, as shown in FIG. 8, the grip portion slider 54A stops the forward movement at the position where the lower surface of the protrusion 54C abuts the forward stopper 61. At this time, the guide cylinder 12 of the wire rod 10
The relative amount L27 of protrusion from the amount of protrusion L25 is the amount of additional movement distance L21 of the gripper slider 54A to the amount L25 of protrusion in advance.
It will be the value which added.

Thus, the guide cylinder 12 has the initial position PS2.
From the forward position PE2, which is a distance L12 from the
In this state, the wire rod 10 is further fed by the additional protrusion amount L21, so that the wire rod tip portion is moved to the initial position PS.
Moving distance L3 from 1 to final delivery position PE1
0 (= (moving distance L12 of the guide slider 55A) +
(The additional protrusion amount L21 of the wire rod 10)).

When the wire rod 10 is delivered to the final delivery position PE1 as shown in FIG. 8, as shown in FIG. 9, the tip end portion of the wire rod 10 is held by the spindle holding member 47C of the winding spindle portion 47. . In this state, the gripping members 6A and 6B on the side of the wire rod supply device 50 that have clamped the wire rod 10 are driven in the directions in which the wire rod 10 is released, whereby the wire rod 10 is only moved to the gripping member 47C on the winding main shaft portion 47 side. It is pinched.

In this state, the wire rod feeding device 50 drives the drive actuator 57 (FIG. 8) to move the grip slider 54A and the guide slider 55A back to their initial positions (FIG. 5). When the guide slider 55A moves backward to the initial position, the guide cylinder 12 fixed to the guide slider 55A also moves to the initial position PS2 (FIG. 8) moved backward by the distance L12. As a result, the guide cylinder 12 is separated from the vicinity of the winding spindle portion 47, and by rotating and traversing the spindle 47A of the winding spindle portion 47 in this state, the wire rod 10 is coiled around the spindle 47A. Is wound around.

When the wire rod 10 is wound into a coil, the wire rod 10 is held by the gripping members 6A and 6B of the wire rod feeding device 50.
And the cutting blades 48C and 48D of the wire rod cutting portion 48 (FIG. 4) supported by the base member 51 of the wire rod feeding device 50 are respectively driven by the drive portion 48A in the direction indicated by the arrow h (that is, the wire rod 10). In a direction in which the wire rod 10 is sandwiched between the guide cylinder 12 and the grasping member 47C of the winding main shaft portion 47.

In this state, by driving the opening / closing drive section 48B, the cutting blades 48C and 48D are closed and the wire rod 10 is cut. The cutting position of the wire rod 10 at this time is a position where the wire rod 10 protrudes from the guide cylinder 12 by a protrusion amount L25. Thus, when the wire 10 is cut, the cutting blade 4
After 8C and 48D are opened by the open / close drive unit 48B, they are moved backward by the drive unit 48A in the direction of arrow i, and a series of winding processing is completed.

(3) Operations and Effects of the Embodiment With the above-mentioned configuration, the wire rod feeding device 50 is in a state where the grip slider 54A and the guide slider 55A are retracted to the initial position (FIG. 5). And the wire rod 1 protruding from the guide cylinder 12 by the protrusion amount L25.
The leading end portion of 0 is set back outside the winding area required for winding processing of the winding main shaft portion 47.

From the initial position, the wire rod feeding device 50 integrally moves the grip slider 54A and the guide slider 55A forward by a predetermined distance L12. At this time, the wire rod 10
The spacing between the gripping members 6A, 6B and the guide tube body 12 that sandwich the pin becomes relatively constant, and the guide tube body 12 and the wire rod 10
The wire rod 10 moves forward by the distance L12 in a state where the relative position of is unchanged.

When the grip slider 54A and the guide slider 55A move forward by a distance L12, the guide cylinder 12
Also, the tip of the wire rod 10 protruding from the guide cylinder 12 enters the winding region of the winding main shaft portion 47, and the guide cylinder 12
Stops at a position close to the parts constituting the winding main shaft portion 47. From this state, only the gripper slider 54A further advances by the distance L21, so that the tip end portion of the wire rod 10 is inserted into the position where it is gripped by the spindle gripping member 47C (FIG. 9) of the winding spindle part 47.

When the spindle holding member 47C of the winding spindle portion 47 clamps the tip end portion of the wire rod 10, the guide cylinder 12 retracts and returns to the outside of the winding area of the winding spindle portion 47 (that is, the initial position). As a result, the winding main shaft portion 47 is attached to the guide cylinder 1.
The winding process of the wire rod 10 can be performed without being interfered by 2.

As described above, in the feeding process of the wire rod 10, the guide tube body 12 is integrated with the wire rod 10 from the initial position where the guide cylinder body 12 escapes outside the winding region of the winding main shaft portion 47 to the position close to the member of the winding main shaft portion 47. Then, the guide cylinder 1 is moved forward, and then only the distance L21 required for the wire rod 10 to be clamped by the gripping member 47C of the winding main shaft portion 47.
The amount L27 of protrusion of the wire rod 10 from the guide tube body 12 is further smaller than that in the conventional case in which the guide tube body 12 is fixed to the outside of the winding main shaft portion 47 by being sent out from the wire rod 10. It becomes the limit. Therefore, since the protrusion amount L27 is small, the tip of the wire rod 10 is accurately positioned.

Further, the guide cylinder 12 is advanced together with the wire rod 10 from the initial position to the position close to the member of the winding spindle portion 47, so that the guide cylinder body 12 is actually moved.
When the wire rod 10 is bent between the gripping members 6A, 6B and the guide tube body 12 and the feeding operation becomes difficult, the amount L21 of the wire rod 10 is significantly smaller than that in the conventional case described above with reference to FIG. It is possible to prevent the occurrence of defective operation.

According to the above configuration, the feed amount of the wire rod 10 by the grip portion 54 and the guide cylinder 12 by the guide portion 55.
By separately controlling the amount of movement of
It is necessary for the guide cylinder 12 that has been released to the outside of the winding region to be advanced into the winding region only when necessary such as when the wire rod 10 is fed out and to be held by the gripping member 47C of the winding main shaft portion 47. The wire rod 10 can be protruded by an appropriate protrusion amount. Thus, the amount of protrusion of the wire rod 10 from the guide cylinder 12 can be reduced, and the positioning accuracy of the tip portion of the wire rod can be improved accordingly.

(4) Other Embodiments In the above embodiment, the case where the feed amount of the wire rod 10 is larger than the movement amount of the guide cylinder 12 has been described. However, the present invention is not limited to this, and the wire rod feed is performed. Amount guide cylinder 1
It may be smaller than the movement amount of 2.

That is, as shown in FIG. 10 (A), the wire rod 10 is sandwiched and held by the holding members 6A and 6B (FIG. 4) in a state where the wire rod 10 projects from the guide cylinder 12 by the projecting amount L41. Slider 54A and guide slider 5
5A is moved forward as a unit by a distance L42. In this state, as shown in FIG. 10B, the relative positions of the guide cylinder 12 and the wire 10 have not changed. In this state, after the gripping members 6A and 6B are opened to release the wire rod 10, the gripper slider 54A and the guide slider 55A are further advanced by a distance L43 as shown in FIG. Only the guide cylinder 12 moves forward while remaining in the original position. As a result, the amount L44 of protrusion of the wire 10 from the guide cylinder 12 can be reduced.

Therefore, in the case where the interference area with the unit provided in the next stage of the wire rod supply device 50 is small, the protrusion amount L44 of the wire rod 10 is made smaller, so that the tip end portion of the wire rod 10 becomes more highly precise. Can be positioned.

In the above-described embodiment, the case where the guide portion slider 55A is subordinately operated by using the engaging means 68 with respect to the grip portion slider 54A has been described, but the present invention is not limited to this, and the grip portion slider is not limited to this. The 54A and the guide slider 55A may be independently driven.

That is, in FIG. 11 in which parts corresponding to those in FIG. 4 are designated by the same reference numerals, a drive actuator 87, which is a separate body from the drive actuator 57 on the gripping portion 54 side, is fixed to the base member 51 in the wire rod supply device 80. The output shaft 87A of the drive actuator 87 is fitted and fixed to a part of the guide portion slider 85A.

Accordingly, the output shaft 8 of the drive actuator 87
By driving 7A in the forward direction indicated by the arrow e, the guide portion slider 85A accordingly moves forward in the direction of the arrow e while being guided by the straight guide rail 52, and the output shaft 8
By driving 7A in the backward direction indicated by the arrow d, the guide slider 85A accordingly retracts in the arrow d direction.

In this way, the grip slider 54A and the guide slider 55A are individually driven and controlled by the separate drive actuators 57 and 87, thereby smoothing the curved wire rod 10 as shown in FIG. 12, for example. It can be performed. That is, in FIG.
After the tip end portion of the wire rod 10 protruding from the guide cylinder 12 is clamped by the spindle holding member 47C of the winding spindle portion 47, FIG.
As shown in FIG. 13A, the winding main shaft portion 47 is traversed by the traverse motor 46 (FIG. 2) in the directions of arrows m and n, and as shown in FIG.
2 is driven by an actuator 87 (FIG. 11) and arrow e
By advancing and retreating in the and d directions, the curved wire rod 10 can be squeezed by the guide cylinder 12.
Thereby, the bending of the wire rod 10 can be removed.

In this way, after the wire rod 10 is wound around the winding main shaft portion 47 to form a coil, the terminal portion of the coil can be corrected, and the formed coil is cut from the wire rod 10. The terminal portion can be straightened more easily than in the conventional case in which the terminal portion is straightened.

Further, in the above-mentioned embodiment, the forward side stoppers 61 and 63 and the backward side stopper 6 are provided on the base member 51.
Although the case where 2 is fixed has been described, the present invention is not limited to this, and a plurality of engaging portions are formed in the base member 51,
A predetermined engaging portion is selected from the plurality of engaging portions, and the forward-side stoppers 61 and 63 and the backward-side stopper 62 are added to this.
May be engaged and fixed. If you do this,
The feed amount of the wire rod 10 and the movement amount of the guide cylinder 12 can be variously set as necessary.

Further, in the above-mentioned embodiment, the case where the present invention is applied to the wire rod supply device 50 of the coil winding device 30 has been described, but the present invention is not limited to this, and the point is that a predetermined amount of wire rod is sent out. The present invention can be widely applied to wire rod supply devices used for other purposes.

[0059]

As described above, according to the present invention, by separately controlling the feed amount of the wire rod and the movement amount of the guide member for holding the wire rod at its tip end,
The amount of protrusion of the wire rod from the guide member can be minimized, whereby the positioning accuracy of the tip end portion of the wire rod can be improved and the wire rod can be reliably sent out.
