Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding method and a device for winding a wire such as a coil provided in a latching solenoid or the like around a bobbin.

[0002]

2. Description of the Related Art When manufacturing electromagnets such as solenoids,
A dedicated winding device for winding the coil wire in multiple layers around a cylindrical bobbin is used. The basic function of this winding device is to continuously feed the wire rod and wrap it around the bobbin by winding the bobbin around the bobbin so that the position of the wire rod can be adjusted at the same time. By feeding in the direction, the wire rods are sequentially laminated.

When the wire is wound around the bobbin, a guide roller provided between the supply source and the bobbin is generally used as a mechanism for giving the wire a reciprocal feed (traverse) in the axial direction of the bobbin. To be done. The guide roller is configured such that a wire rod is hung on its peripheral surface to guide the wire rod in the bobbin direction, and at the same time, the guide roller itself can be moved in the axial direction in order to traverse the wire rod with respect to the bobbin.

This guide roller is effective for closely winding the wire rods in the traverse direction by setting the traverse speed and the moving distance on the basis of the wire rod winding width of the bobbin and the outer diameter of the wire rod. Is.

[0005]

When winding a wire rod around a bobbin, it is necessary to apply a certain tension to the wire rod to be supplied. For example, Japanese Patent Laid-Open No. 1-196
In Japanese Patent Laid-Open No. 110, two guide rollers are arranged in front of a path to a bobbin, and these guide rollers can be moved up and down, so that a device for winding the wire material while always applying a uniform tension is disclosed. It is disclosed.

However, due to such tension, as the wire is wound around the bobbin, warp deformation such that the axis of the bobbin bends is likely to occur. Therefore, a phenomenon occurs in which the wound wire rods do not overlap each other in the bobbin width direction and the arrangement is disturbed. That is, since the bobbin warps so that it swells to the side where the wire rod is introduced, there is a tendency for the adhesion between the wire rods to become loose on the surface facing the wire rod,
On the other side of the surface, the wire rods tend to interfere tightly with each other, so that the balance of the wire rod arrangement is lost, and such disorder is likely to occur.

Further, if the tension at the time of supplying the wire rod fluctuates, the outer diameter of the wire rod also changes accordingly. Therefore, when the outer diameter of the wire rod or the length of the wire winding width of the bobbin is used as a reference, it is affected by the change in the outer diameter of the wire rod, and similarly, the arrangement of the wire rod wound on the bobbin is disturbed. ..

As described above, when the wire material is actually supplied to the bobbin side and is wound, the aligned winding is easily damaged by various factors. Therefore, even if the movement of the guide roller promotes the traverse of the wire rod when it is wound on the bobbin, the guide roller is controlled in response to subtle changes such as changes in the outer diameter of the wire rod and warp deformation of the bobbin. Is difficult to do.

Therefore, when the wire rod is simply traversed by the guide rollers, in the actual winding, an error is likely to occur in the winding pitch and stroke speed of the wire rod in the bobbin width direction. Therefore, as the wire rod is wound up, this error gradually accumulates, and in the finished product, the wire rod 51 wound around the bobbin 50 is greatly disturbed especially on the front surface side as shown in FIG. 8A. I will end up. This disturbance is
This appears as uneven density of the wire material 51 or partial bulging to the outside.

If the wire rods 51 cannot be accurately wound in this manner, the length of the wire rods 51 wound around the bobbin 50 will also change for each product. Therefore, the length of the coil varies from product to product, and the resistance value varies.

Further, if the cylindrical surface portion formed by the wire 51 has irregularities, the mold resin 52 serving as the housing of the solenoid also becomes bulky, which tends to hinder miniaturization.

[0012] Such a problem is not limited to the coil winding of the solenoid but also in the field of winding various kinds of wire rods on the bobbins, and there is a problem that the length of the wire rod supplied as a product varies.

A problem to be solved in the present invention is to enable wire rods to be wound around a bobbin with high precision, to make the winding length of the wire rods uniform and to improve the profile after winding. ..

[0014]

According to the present invention, a tension is applied to a wire rod between a supply side of the wire rod and a bobbin for winding the wire rod, and the bobbin is rotationally driven to wind the wire rod around the bobbin. Further, in a winding method in which the wire rod is continuously laminated by traversing the wire rod in the axial direction of the bobbin, the wire rod is wound on the bobbin during at least one layer winding at the beginning of winding the wire rod on the bobbin. The angle of incidence is inclined so as to be biased toward the wire rod previously wound around the bobbin, and after winding at least one layer of the wire rod around the bobbin, the constraint of the incident angle of the wire rod is released, and the wire rod is simultaneously introduced into the bobbin. The wire rod is adapted to pass along the traverse of the wire rod while supporting the wire rod at its free end.

According to a second aspect of the present invention, the wire rod is tensioned between a wire rod supply side and a bobbin for winding the wire rod, and the bobbin is rotationally driven to wind the wire rod around the bobbin. In a winding device that continuously stacks the wire rods over the entire axial direction, a path setting member that engages with the wire rods and adjusts an incident angle to the bobbin, and a wire rod that goes toward the bobbin. Guide rollers are arranged so as to be hung on the circumferential surface and guided, and the path setting member and the guide roller are rotatable around the axis and movable in the axial direction by contact with the circumferential surface of the wire, and the path setting member is It is characterized in that the position in the axial direction is variable by an external drive system.

[0016]

In the initial stage of winding the wire rod around the bobbin, the wire rod is introduced to the bobbin side by inclining the incident angle of the wire rod with respect to the bobbin toward the previously wound wire rod side. For this reason, the wire rod in the winding process exerts an action force that pushes the already wound wire rod in the axial direction of the bobbin, whereby the wire rod wound around the bobbin can be closely aligned.

After winding at least one layer of the wire rod, the wire rod is wound while naturally advancing in the axial direction of the bobbin following the recessed groove formed by the wire rods in the lower layer. In this process, the wire rod is supported at the free end before it is introduced into the bobbin, so the position of the wire rod before introduction should be moved in the direction in which the winding surface advances in response to the movement of the wire rod on the bobbin side. Therefore, the upper-layer wire rod can be closely wound along the row of the lower-layer wire rod.

Further, in the apparatus, since the path setting member is shifted from the outside in the axial direction of the wire, the wire rod is moved so as to exert an action force in the direction of pushing the wire rod already wound during the initial winding. You can decide the path.

[0019]

1 is a schematic perspective view showing a path of a wire rod according to a winding method of the present invention, and FIG. 2 is a schematic plan view thereof.

In the figure, a wire A is drawn out from an uncoiler (not shown) around which the wire A is wound, and in a state of being tensioned, a path setting member 1 (hereinafter referred to as "path setting") having a roller rotatable about an axis. (Referred to as “roller 1”) and two guide rollers 2 and 3, and is introduced into the bobbin 4, and the wire A is wound by rotationally driving the bobbin 4.

Path setting roller 1 and guide rollers 2 and 3
Is a substantially V-shaped groove 1a, 2a, 3 for hanging the wire A
A has a peripheral surface and is rotatable in the direction of the arrow in the figure by the frictional force when the wire A passes through the grooves 1a to 3a. Further, the guide rollers 2 and 3 are both movable in the axial direction, and the path setting roller 1 is moved between the positions shown by the solid line and the broken line in FIG. 2 by the driving force from the outside. The guide rollers 2 and 3 are merely constrained in the posture of their axes, and can freely move in accordance with the path of the wire A.

FIG. 2 shows an initial state in which the wire A is wound around the bobbin 4.

The wire A is wound up one layer from the left side flange 4a side of the bobbin 4 toward the right side flange 4b side, and returns from the right side flange 4b to the left side flange 4a as shown in FIG. The second layer is rolled up. After that, the wire A is naturally copied next to the adjacent winding wire and is wound while being restricted in position by the recessed groove between the lower wire A, and the movement of the wire A itself at this time is used. By doing so, the flanges 4a and 4b are traversed, and the wire rod A is laminated.

When the wire A is wound on the bobbin 4, the path setting roller 1 is attached to the flange 4a on the left side of the bobbin 4 as shown in FIG.
It is located outside of. At this time, when the wire rod A is hung on the bobbin 4, the guide rollers 2 and 3 into which the wire rod A fits in the grooves 2a and 3a are not subject to any restraint in the axial direction. These guide rollers 2 and 3 also move to the path setting roller 1 side with reference to the position 1 and the winding position of the bobbin 4 at the end. In other words, the wire A has its supply side on the groove 1a of the path setting roller 1.
Since the bobbin 4 is constrained to a position away from the winding surface and the end of the bobbin 4 is constrained by the bobbin 4, the guide rollers 2 and 3 are respectively displaced to the setting roller 1 side by the urging force of the wire rod A under tension. To do.

When the bobbin 4 is driven in this initial state,
Since the path setting roller 1 and the guide roller are all arranged outside the flange 4a, the wire 4 is wound at an incident angle deviated to the flange 4a side with respect to the axis of the bobbin 4. For this reason, in the wire rods A that are lined up in order from the first winding, adjacent wire rods come into tight contact with each other. Then, when the number of windings increases and the winding surface of the wire A gradually moves to the right flange 4b side, the guide roller 3 in the second stage is affected by the movement of the wire A between the bobbin 4 and In FIG. 2, it gradually moves to the right. Also, this guide roller 3
Similarly, the first-stage guide roller 2 also moves to the right according to the movement of the wire A between them.

Thus, in the initial stage of winding, the wire A is attracted to the flange 4a side, and even if the wire A gradually moves to the flange 4b side, the guide rollers 2,
By utilizing the fact that 3 is free to move in the axial direction, the guide rollers 2 and 3 can be made to follow the movement of the wire rod A. Therefore, the wire A can be wound around the bobbin 4 while having tension by being wound around the path setting roller 1 and the two guide rollers 2 and 3.

After the wire A is wound in the axial direction of the bobbin 4, the path setting roller 1 is moved to the position shown by the broken line in FIG. As a result of this movement, the wire A having tension between the path setting roller 1 and the bobbin 4 will move into the grooves 2a, 3a.
Similarly, the guide rollers 2 and 3 are also moved to the positions indicated by broken lines by the engaging force with respect to. As a result, when the path surface of the wire rod A of the path setting roller 1 is substantially aligned with the center of the bobbin 4 in the axial direction, the grooves 2a and 3a of the guide rollers 2 and 3 are
The arrangement is aligned with the groove 1a of the path setting roller 1 in a plan view.

If the winding of the wire A by the bobbin 4 is continued even after this position setting, when the wire A is wound around the bobbin 4, the cross sections of the wire A contact each other as shown in FIG. 3B. As a result, the wire A is wound so as to follow the contact surface. Therefore, as mentioned above,
As long as the wire A is wound, it can behave as if it traverses itself, and even after hitting the flanges 4a and 4b, the direction is changed and the winding advances toward the flange on the other side.

In response to such movement of the wire A, the bobbin 4
Since the wire rod before being introduced into the wire rod is guided by the guide rollers 2 and 3 which are arranged in a posture parallel to the axis of the bobbin 4, these guide rollers 2 and 3 are also aligned in the axial direction according to the traverse of the wire rod A. Traverse to. In addition to the guide rollers 2 and 3, the path setting roller 1
Similarly, if it is free to move in the axial direction, the wire A
It is also possible that the rollers 1 to 3 move around in accordance with the movement of the above and substantially feed the wire A to the bobbin 4 side as a free end support.

As described above, when the wire A is wound around the bobbin 4, the wire is pressed against the flange 4a so that the wire A is gradually wound in the width direction of the bobbin 4 as shown in FIG. As in (b), they can be tightly contacted and wound tightly. And 1
After winding the layer, the path setting roller 1 and the guide rollers 2 and 3 are arranged at the positions shown by the broken lines in FIG. 2 so that the incident angle becomes similar to the winding of the wire A on the bobbin 4. These rollers 1 to 3 are shifted along with the movement of the wire A itself. Therefore, the wire A is not
Since the bobbins 4 are wound around the bobbin 4 under the tension of 3 to 3, the tension load and the aligned winding are possible.

FIGS. 4 and 5 show the outline of the winding device capable of winding the wire A as described above. FIG. 4 is its plan view and FIG. 5 is its front view.

In the figure, the winding device is mounted on the base 5 by 3
A series of guide units 6, 7, 8 are arranged, and a winding station 9 for rotating the bobbin 4 by attaching and detaching the bobbin 4 is provided at the right end. A rail 5a is provided on the upper surface of the base 5 so that the guide units 6 to 8 can be freely moved and fixed at arbitrary positions.

The guide units 6 to 8 are provided in FIGS.
The path setting roller 1 and the guide rollers 2 and 3 shown in FIG.

The path setting roller 1 is incorporated in the support shaft 1b protruding from the guide unit 6, and this support shaft 1
It is rotatable around b, and the wire A is hung on the groove 1a formed on the peripheral surface of the groove 1a to pass it.

The guide rollers 2 and 3 are mounted on the support shafts 2b and 3b protruding from the guide units 7 and 8, respectively. FIG. 6 shows an example of the structure of the guide roller 2. The guide roller 2 is connected to the support shaft 2b through a ball gauge 2c in which a large number of steel balls 2d are rotatably incorporated around the support shaft 2b. Such a ball gauge 2c is generally used, and for the fixed support shaft 2b,
By utilizing the rolling of the steel ball 2d, the guide roller 2 is free to rotate around the support shaft 2b and move in the axial direction. The one guide roller 3 is also supported by the support shaft 3b protruding from the guide unit 8 in a similar structure, and both the rotation around the support shaft 3b and the movement in the axial direction are possible.

The guide unit 6 of the path setting roller 1 is provided with a stepping motor 1e for moving the support shaft 1b in the axial direction. The output shaft of the stepping motor 1e is connected to a support shaft 1b by a coupling 1f having a screw gear mechanism, and the drive shaft 1b is driven during driving.
By moving, the position of the path setting roller 1 can be changed as described with reference to FIG. The stepping motor 1e, the support shaft 1b, and the like are connected to a bracket 6b that is vertically movable with respect to the frame 6a of the guide unit 6 so that the level of the path setting roller 1 can be changed.

Further, position detecting sensors 1g and 1h are provided for detecting the position of the path setting roller 1 when the position is changed. These position detection sensors 1g, 1
As for h, as shown in FIG. 4, one position detection sensor 1g is disposed so as to substantially face the bobbin 4, and the other position detection sensor 1h is provided close to the base 5 side.

The winding station 9 is provided with a variable speed winding motor 9a for driving the bobbin 4 to rotate, and the bobbin 4 is detachably attached to the output shaft 9b thereof. Output shaft 9b
Is provided with a handle 9c for manual operation, and when the tip end of the wire A is wound on the bobbin, the operation of starting to hang it is performed while turning the handle 9c.

In the illustrated example, the path setting roller 1, the guide roller 2 and the other guide roller 3 are arranged in this order up to the bobbin 4, but the arrangement is not limited to this order and any arrangement may be used. It is also possible to arrange the path setting roller 1 at the final stage.

The path setting roller 1 described with reference to FIGS. 1 and 2.
The movement of the wire is controlled so that the wire A is wound one turn in the width direction of the bobbin 4 and then moved from the position shown by the solid line in FIG. 2 to the position shown by the broken line.

FIG. 7 is a schematic diagram of a control block for moving the path setting roller 1.

Signals from the position detection sensors 1g and 1h are input to the main controller 10a which controls the operations of the stepping motor 1e and the winding motor 9a, and the operation of the stepping motor 1e is controlled by the output signals thereof. In addition, the controller 1 that controls the operation of the winding motor 9a
The initial condition setting circuit including 0b is connected to the main controller 10a. This initial condition setting circuit starts winding the wire A around the body of the bobbin 4 and winds the wire A from the left flange 4a to the right flange 3a shown in FIG. Input the signal. In this case, the control factors include the outer diameter of the wire A, the outer diameter of the body of the bobbin 4 around which the wire A is wound, the distance between the flanges 4a and 4b, and the like.
A signal is output by calculating how many revolutions b the wire A is wound around the entire body of the bobbin 4.

At the initial winding start stage, the path setting roller 1 is at the position indicated by the solid line in FIG. 2, and the position detecting sensor 1h detects this and inputs the signal to the main controller 10a. Then, when the wire A reaches the flange 4b side from the beginning of winding the bobbin 4 onward, a signal is input from the controller 10b on the initial condition setting circuit side to the main controller 10a. As a result, the stepping motor 1e is energized,
A pulse for oscillating the path setting roller 1 to the position shown by the broken line in FIG. 2 is oscillated. Then, when the path setting roller 1 reaches a predetermined position, the position detection sensor 1g inputs the detection signal to the main controller 10a. Even if the position of the path setting roller 1 is displaced, the position of the path setting roller 1 is corrected by pulse oscillation based on the signal from the position detection sensor 1g based on the main controller 10a.

In the above structure, the wire A is wound around the body of the bobbin 4 attached to the output shaft 9b of the winding station 9 from the path setting roller 1 via the two-stage guide rollers 2 and 3. This initial winding is performed manually by using the handle 9c as described above, and the tip of the wire A is wound so as to hit the left flange 4a in FIG.

At the start of the work of winding the wire A around the bobbin 4, the path setting roller 2 is at the position indicated by the solid line in FIG. 2 and outside the left flange 4a of the bobbin 4.
By passing the wire A through the grooves 2a and 3a of the guide rollers 2 and 3 as described above, the guide rollers 2 and 3 are also arranged so as to be displaced toward the path setting roller 1 side.

When the winding motor 9a operates in this state, the wire rod A whose incident angle with respect to the bobbin 4 is slightly inclined to the flange 4a side is wound up so as to be strongly tightened to the flange 4a side, and the first layer is formed. The wire A is tightly wound in the axial direction of the bobbin 4.

When the controller 10b of the initial condition setting circuit detects the rotation of the winding motor 9a and detects that the wire A has reached the right flange 4b, the controller 1
0b inputs a signal to the main controller 10a. This allows
The stepping motor 1e operates to move the support shaft 1b and stop the path setting roller 1 at the position shown by the broken line in FIG. The position of the path setting roller 1 at this time is detected by the position detection sensor 1g, and the path setting roller 1 is positioned so that the groove 1a substantially corresponds to the center of the bobbin 4 in the axial direction.

During the movement of the path setting roller 1,
The operation of the winding motor 9a is temporarily stopped so that the wire A is not wound around the bobbin 4.

Due to the movement of the path setting roller 1 as described above, the guide rollers 2 and 3 of the two stages are also moved following the position of the broken line in FIG. When the winding motor 9a is operated again, the wire A is wound from the flange 4b side onto the first layer wound around the body of the bobbin 4, as shown in FIG.

Here, in the wire rod A of the first layer wound around the body of the bobbin 4, there is formed a groove B slightly recessed between the adjacent windings, and this groove B is of the first layer. Runs spirally on the surface. Therefore, when the wire A is wound around the surface of the first layer as the second layer, the wire A is wound so as to be dropped into the groove B. That is, the wire A of the second layer is wound so as to follow the groove B naturally, and the groove B has a spiral shape.
In, the wire rod A is wound around the first layer wire A while naturally moving to the left. In addition, the wire A of the third layer after winding the second layer also has the same procedure as the flange 4a.
Is wound while advancing from one side toward the other flange 4b side.

As described above, when the wire A is wound on the bobbin 4, the flanges 4a and 4b are traversed. In response to this movement, since the two guide rollers 2 and 3 are both movable in the axial direction, these guide rollers 2 and 3 oscillate corresponding to the position of the wire A wound on the bobbin 4. When the path setting roller 1 can be moved in the axial direction, if the path setting roller 1 has traverse propagation of the wire A, the path setting roller 1 also freely sways.

Therefore, if the operation of densely winding the wire A between the flanges 4a and 4b is performed only during the winding of the first layer, the position of the winding surface of the wire A with respect to the bobbin 4 will be adjusted thereafter. The position and posture of the path can be freely changed according to the movement of the wire A. Therefore, not only the first layer can be wound in an aligned manner, but also the wire material A in the upper layer can be closely aligned and wound.

In the initial winding of the wire A,
As described above, only one layer is wound by the arrangement of the path setting roller 1 and the guide rollers 2 and 3 shown by the solid line in FIG. On the other hand, if the path setting roller 1 is on the right side of the position of the broken line in FIG. 2 and the stroke of the position of the solid line in the drawing is allowed to the symmetrical position, the second and subsequent layers can be moved. It is clear that the wire A can also be similarly wound with uniform density.

FIG. 8B is a vertical sectional view of a coil housing for a solenoid obtained by a winding device to which the method of the present invention is applied.

As shown in the figure, the wire rods A are stacked in line around the bobbin 4, and the wire rods A which are adjacent to each other in any layer.
They are closely arranged with each other. Since the wire A on the front surface side is also wound following the spiral groove formed in the wire A on the lower layer, a winding having no unevenness on the surface can be obtained.

Since the wire A can be aligned and wound in this manner, the length of the wire A can be made constant for each product, and the resistance value does not vary for each product. Further, since the surface of the winding of the wire A does not have irregularities or bulges locally, it is not necessary to allow the mold resin 52 to have a sufficient bulk. Therefore, the coil can be downsized and the space occupied in the device can be reduced, so that the device can be downsized.

In the embodiment, the coil for solenoid has been described as an example of the wire rod, but it is needless to say that the method and apparatus of the present invention can be applied to the winding of various other wire rods.

[0058]

According to the present invention, at the beginning of winding, the wire is wound while exerting an acting force so as to pull it toward the outer side in the axial direction of the bobbin. Can be wrapped around. Then, after winding at least one layer, the wire rod is wound by the movement of the wire rod itself while following the groove between the already wound lower layer wire rods, and at this time, the wire rod is properly incident according to the movement of the winding surface of the wire rod on the bobbin. Since the path is free so as to form an angle, the wire rod can be wound up following the groove of the wire rod in the lower layer.

Therefore, if at least one layer of wire material wound around the body of the bobbin is wound around the bobbin by pulling it outward and aligned and wound, the wire material of the upper layer is also accurately aligned and wound. be able to. For this reason, it is possible to obtain a good product in which the length of the wire can be made uniform and there is no unevenness or partial bulge on the surface after winding.
