Description

Winding device and winding method

The invention relates to a winding device and a winding method.

At present, for example, Japanese Patent Laid-Open No. JP2000-128433A discloses a tension device that is installed in a winding machine that winds a wire with a core to form a coil, and applies a predetermined tension to the wire. As shown in Figure 15, this tension device is equipped with: a winch 3 for hanging the wire 2 unwound from the wire source; a tension arm 4 that can rotate around the rotation fulcrum 4a at the base end; and a guide wheel 5, It is installed at the front end of the tension arm 4, and after passing the wire 2 unwound from the winch 3, it is steered to guide it to the winding machine; the elastic member 6, which is at the rotation fulcrum 4a of the tension arm 4 and the guide wheel At a predetermined position between 5, the tension arm 4 is given an elastic force corresponding to the rotation angle; the potentiometer 7 detects the rotation angle of the tension arm 4; the unwinding motor 8 is detected by the potentiometer 7 The rotation of the winch 3 is controlled so that the output rotation angle becomes a predetermined angle, and the speed of the wire 2 from the winch 3 to the winding machine (not shown) via the guide wheel 5 is controlled.

Here, the wire 2 is guided to the winding machine via the guide wheel 5, and is wound on the winding core. Regarding the unwinding speed of the wire 2 unwinding from the conventional tension device, the rotation of the winch 3 is controlled so that the rotation angle of the tension arm 4 becomes a predetermined angle, so as to ensure the unwinding speed and the winding core of the wire 2 The balance between the coiling speed of the coiled wire. In addition, a predetermined tension is applied to the wire 2 through the tension arm 4 to which an elastic force is imparted by the elastic member 6.

When the winding speed of the wire rod wound by the winding core fluctuates, the tension of the wire rod 2 fluctuates, but the amount of fluctuation is absorbed by the tension arm 4 changing the rotation angle. In addition, since the change in the rotation angle of the tension arm 4 is fed back to the rotation of the winch 3 via the potentiometer 7, the rotation angle of the tension arm 4 immediately becomes a predetermined angle, and the unwinding motor 8 is used to adjust the rotation of the winch 3 At the rotation speed, the tension applied to the wire 2 is restored to a predetermined value.

[Problems to be solved by the invention] As described above, in the conventional tension device shown in FIG. 15, the rotation angle of the tension arm 4 is changed to absorb the fluctuation of the winding speed of the wire 2. However, when the wire 2 is wound on a core of different diameters with different cross-sectional outer diameters, for example, a core having a rectangular cross-sectional shape and having significantly different short sides and long sides, the core rotates once During the period of time, the speed of the wire 2 wound around the core will periodically change significantly. As a result, the rotation angle of the tension arm 4 that absorbs the change in speed is significantly increased.

That is, a case where the wire 2 unwound from the winch 3 is turned on the guide pulley 5 so as to bend at a substantially right angle with respect to the tension arm as shown in FIG. 15 and guided to the winding machine will be described. The winding speed of the wire 2 in the winding machine is increased, and when the predetermined length L1 is over-winded per unit time, the guide wheel 5 is also pulled toward the predetermined length L1 of the multi-winding as shown by the solid arrow Move on the side of the winding machine. In addition, the tension arm 4 provided with the guide wheel 5 at the front end overcomes the elastic force of the elastic member 6 to rotate, thereby allowing the guide wheel 5 at the front end to move by a predetermined length L1.

However, in the case where the speed of the wire 2 wound on the winding core of the winding machine changes significantly, and its speed immediately rises significantly, the guide wheel 5 is strongly pulled by the wire 2 and the guide wheel is provided at the tip 5. The rotation of the tension arm 4 that absorbs the fluctuation cannot follow the trend of the pulled guide wheel 5. As a result, tension exceeding the elastic force imparted by the elastic member 6 is temporarily imparted to the wire 2 provided between the guide pulley 5 and the core of the tension arm 4.

Conversely, in the case where the winding speed of the wire 2 in the winding machine is reduced, and the amount of winding per unit time is reduced by the predetermined length L2, the guide pulley 5 is wound from the winding direction due to the elastic force of the elastic member 6 The direction in which the wire machine is separated is moved by the reduced predetermined length L2. In addition, the tension arm 4 provided with the guide wheel 5 at the front end rotates due to the elastic force of the elastic member 6, thereby allowing the guide wheel 5 at the front end to move by a predetermined length L2 as shown by the dashed arrow.

However, in the case where the speed of the wire 2 of the winding core wound in the winding machine changes significantly, and the speed of the wire 2 winding of the winding core in the winding machine immediately decreases significantly, the wire 2 is pulled The force of the guide wheel 5 is immediately reduced significantly, and the tension arm 4, which is provided with the guide wheel 5 at the front end and absorbs the fluctuation, cannot follow its rotation even if the elastic force of the elastic member 6 is used due to its inertial force. As a result, the wire 2 between the guide roller 5 and the winding core provided at the tip of the tension arm 4 may temporarily slack. Therefore, in the conventional tension device, when the speed of the wire 2 wound on the core of different diameters in the winding machine changes significantly, it is difficult to maintain the tension of the wire 2 supplied to the winding machine. It is a constant problem point.

The object of the present invention is to provide a winding device and a winding method that can keep the tension of the wire wound around the winding core constant even when the winding speed of the wire material in the winding core fluctuates significantly.

[Means for solving problems] According to an aspect of the present invention, there is provided a winding device, the winding device is provided with: a winding core; a wire unwinding mechanism that supplies the wire to the winding core; and an accumulation mechanism that unwinds the wire from the wire unwinding mechanism The speed of the aforementioned wire is decelerated or accelerated; a tension device which applies tension to the aforementioned wire supplied from the aforementioned wire unwinding mechanism to the aforementioned winding core; a winding core rotating unit which rotates the aforementioned winding core, thereby causing the aforementioned wire The wire supplied by the winding mechanism and tensioned by the tension device is wound on the winding core; and a controller that controls the accumulation mechanism and the wire unwinding mechanism, and the controller is wound on the rotating The average winding speed of the wire of the winding core is to control the wire unwinding mechanism so that the wire unwinding mechanism is controlled so that the speed of the wire unwinding from the wire unwinding mechanism is the same as that of the rotating winding core. The accumulating mechanism is controlled so that the winding speed of the wire rod is equal.

In addition, according to another aspect of the present invention, there is provided a winding method, the winding method is by rotating the winding core, so that the wire supplied from the wire unwinding mechanism and tensioned by the tension device is wound on the coil. The core unwinds the wire from the wire unwinding mechanism at an average winding speed of the wire wound on the rotating winding core, and decelerates or accelerates the speed of the wire unwinded from the wire unwinding mechanism, Therefore, it is equal to the winding speed of the wire rod wound on the rotating winding core.

[Effects of Invention] According to the aspect of the invention described above, even when the winding speed of the wire rod in the winding core changes significantly, the tension of the wire rod wound around the winding core can be kept constant.

In addition, the winding machine 11 in the winding device 10 of the present invention rotates the winding core 12 around the shaft, so that the wire 13 is wound around the winding core 12. The winding core 12 of this embodiment has a reel portion 12a for winding the wire 13 and a flange portion 12b provided on both end surfaces of the reel 12a and restricting the winding width of the wire 13.

In this embodiment, the case where the cross-sectional shape of the reel part 12a is rectangular (FIG. 9-11) is shown.

In addition, the winding machine 11 is provided with a guide mechanism 51 that guides the wire 13 wound around the winding core 12 in the rotation axis direction. The guide mechanism 51 is provided with a support pin 52 which is provided on the base plate 15a in parallel with the axis of rotation of the winding core 12 and is provided so as to be movable in the axial direction; and a guide member 53 which is mounted on the front end of the support pin 52, and The movement of the wire 13 in the axial direction of the winding core 12 is restricted; the guide motor 54 (FIG. 2) moves the support pin 52 in the axial direction.

As shown in FIG. 2, the guide motor 54 is attached so that its rotating shaft 54 a is adjacent to the support pin 52 and is parallel to the support pin 52. A ball screw 55 is provided coaxially on the rotating shaft 54a. In addition, a female screw member 56 screwed with the ball screw 55 is attached to the base end of the support pin 52.

Therefore, when the guide motor 54 is driven to rotate the ball screw 55, the support pin 52 moves in the axial direction together with the female screw member 56 that is screwed with the ball screw 55 to move, so that the support pin 52 is provided with The guide member 53 at the leading end moves in the direction of the rotation axis of the winding core 12. In addition, the guide member 53 is configured to sandwich the wire 13 from both sides in the rotation axis direction of the winding core 12 and restrict the passing position of the wire 13 in the rotation axis direction (FIGS. 12 and 13 ).

As shown in FIG. 1, the winding device 10 further includes an accumulation mechanism 60 that decelerates or accelerates the wire 13 unwound from the wire unwinding mechanism 21 at a predetermined speed. In this embodiment, a case where the accumulation mechanism 60 is provided between the wire unwinding mechanism 21 and the tension device 31 is shown. In the figure, a case where the accumulation mechanism 60 is provided on the vertical plate 30 is shown.

The accumulation mechanism 60 in the figure includes: a pair of fixed rollers 61a, 61b, which are provided along the conveying path of the wire 13 so as to guide the wire 13; The direction intersecting with the conveying path of the wire rod 13 is arranged between a pair of fixed rollers 61a and 61b so as to move in the vertical direction (Z-axis direction) in this embodiment; a servo motor 64 that moves the movable roller 63 .

In this embodiment, a pair of fixed rollers 61 a and 61 b are provided on the vertical plate 30 along the extending direction of the wire 13 that is unwound from the wire unwinding mechanism 21 and turned horizontally by the first turning pulley 32. The vertical plate 30 is provided with a ball screw 66 extending in the vertical direction so as to be located between the pair of fixed rollers 61a and 61b. The rotation shaft of the servo motor 64 is connected to the ball screw 66 so as to be able to rotate the ball screw 66. The movable table 67 is screwed with the ball screw 66, and the movable roller 63 is pivotally supported on the movable table 67. In addition, the control output of the controller 46 is connected to the servo motor 64.

In the accumulation mechanism 60, when the servo motor 64 is driven to rotate the ball screw 66 in accordance with a command from the controller 46, the movable table 67 screwed therewith in the vertical direction moves together with the movable roller 63. The wire 13 turned by the first turning pulley 32 toward the horizontal direction passes through the lower side of the pair of fixed rollers 61a, 61b, and the wire 13 located between the pair of fixed rollers 61a, 61b is wound from above and is located above it. The movable roller 63.

Therefore, as shown in FIG. 3, when the servo motor 64 is driven to raise the movable roller 63 as indicated by the broken arrow, the vertical distance between the pair of fixed rollers 61a, 61b and the movable roller 63 is enlarged. Next, the wire 13 having a length that is twice the vertical distance between the pair of fixed rollers 61a and 61b and the movable roller 63 is accumulated between the pair of fixed rollers 61a and 61b. Therefore, when the movable roller 63 is in the middle of ascent, even if the wire rod 13 is unwinded from the wire rod unwinding mechanism 21 at a constant speed, a part of the wire rod 13 is accumulated between the pair of fixed rollers 61a and 61b. Therefore, the wire rod 13 also slows down to reduce the speed.

Conversely, as shown in FIG. 4, when the servo motor 64 is driven so that the movable roller 63 is lowered, the vertical distance between the pair of fixed rollers 61a, 61b and the movable roller 63 is shortened, and the accumulated wire 13 is discharged. . Therefore, when the movable roller 63 is in the middle of descending as indicated by the dotted arrow, even if the wire 13 is unwound from the wire unwinding mechanism 21 at a constant speed, the discharged wire 13 is added to the wire, so the wire 13 is also accelerated And increase its speed.

In addition, the winding device 10 is further provided with: an unwinding speed detection sensor 70 as an unwinding speed detection unit, which detects the speed of the wire 13 moving toward the tension device 31 through the accumulation mechanism 60; as the winding speed The winding speed detection sensor 80 of the detection unit detects the speed of the wire 13 passing through the tension device 31 toward the winding core 12.

The winding speed detection sensor 80 of this embodiment is provided on an auxiliary plate 82 erected on the end of the housing 19 on the side of the winding machine 11. The auxiliary plate 82 is provided with a pair of rollers 81 and 81 pivotally supported so as to sandwich the wire 13, and a first encoder 83 that detects the rotation angle of any one of the rollers 81.

On the other hand, the unwinding speed detection sensor 70 of this embodiment is provided on the vertical plate 30 on the downstream side of the accumulation mechanism 60. The vertical plate 30 is provided with a pair of rollers 71 and 71 pivotally supported so as to sandwich the wire 13, and a second encoder 73 that detects the rotation angle of any one of the rollers 71.

In addition, in the housing 19, a controller 46 that controls the winding motor 14 constituting the core rotation unit and the guide motor 54 in the guide mechanism 51 is housed. The controller 46 houses a CPU that controls the winding operation performed by the winding device 10, and a memory 46a as a storage unit that stores information or data necessary for the processing operation of the CPU. The memory 46a stores, for example, a predetermined angular velocity ω which will be described later. In addition, an input device 46b for inputting the information is connected to the controller 46.

Therefore, the control output from the controller 46 is connected to the winding motor 14 and the guidance motor 54 respectively. The controller 46 is configured to be able to perform so-called neat arrangement winding. The aforementioned neat arrangement winding is to rotate the winding core 12 at a constant speed by driving the winding motor 14 and to control the guide motor 54 every time When the winding core 12 makes one revolution, the guide member 53 is moved in the rotation direction of the winding core 12 by an amount equivalent to the outer diameter of the wire 13 so that the wire is supplied from the wire unwinding mechanism 21 and is tensioned by the tension device 31 13 is wound in close contact with the winding core 12 (FIGS. 12 and 13 ).

In addition, the detection output of the rotation angle sensor 16 is connected to the control input of the controller 46, which is configured to always recognize the rotation angle of the winding core 12 rotating at a constant speed.

On the other hand, the unwinding motor 26 in the wire unwinding mechanism 21 is configured to be able to change the rotation speed of the rotating shaft 26a. The winch 24 rotatably driven by the unwinding motor 26 is configured to change the unwinding speed of the wire 13 by changing its rotation speed. In addition, the control output of the controller 46 is also connected to the unwinding motor 26 in the wire unwinding mechanism 21. The controller 46 controls the wire unwinding mechanism 21 together with the wire winding motor 14 so as to supply the wire 13 at a speed equal to the average winding speed of the wire 13 wound on the rotating core 12.

In addition, the controller 46 decelerates or accelerates the wire 13 unwound from the wire unwinding mechanism 21 at an average winding speed, and makes the speed equal to the winding speed of the wire 13 curled by the rotating core 12 , The servo motor 64 in the accumulation mechanism 60 is controlled.

Specifically, the controller 46 is provided with an arithmetic circuit 46c as an arithmetic unit. The arithmetic circuit 46c is configured to be able to calculate the calculated winding speed or the calculated average winding speed of the wire 13 wound on the rotating core 12 through the information or data stored in the memory 46a. In addition, the controller 46 controls the wire unwinding mechanism 21 to supply the wire 13 based on the calculated average winding speed calculated by the arithmetic circuit 46c, and to decelerate or increase the wire 13 unwinding from the wire unwinding mechanism 21 The accumulating mechanism 60 is controlled in the manner of calculating the winding speed calculated by the arithmetic circuit 46c.

In this embodiment, since the unwinding speed detection sensor 70 or the winding speed detection sensor 80 is provided, the detection output of the first encoder 83 and the second encoder 73 is controlled by the controller 46 Enter the connection. In addition, the controller 46 detects the actual measured unwinding speed or the actual measured winding speed, and the speed of the wire 13 unwinding from the wire unwinding mechanism 21 and decelerated or accelerated by the accumulating mechanism 60 is compared with the speed of the wire 13 wound on the coil. The feedback control is performed so that the winding speed of the wire 13 of the core 12 is equal.

Next, the winding method of the present invention using the above-mentioned winding device will be described.

The winding method of the present invention is a method in which the winding core 12 is rotated about an axis, and the wire 13 supplied from the wire unwinding mechanism 21 and tensioned by the tension device 31 is wound on the winding core 12.

Since the above-mentioned winding device 10 is used, as shown in FIG. 1, the wire 13 is wound on the reel 18 and stored, and the wire 13 unwound from the reel 18 as the source of the wire passes through the through hole 22a of the flat plate 22. The plurality of small rollers 23a overcome the curling characteristics, and are wound on the winch 24 constituting the wire unwinding mechanism 21.

In addition, the wire 13 extending from the winch 24 is turned by the first turning pulley 32 to face the horizontal direction, and passes under the pair of fixed rollers 61 a and 61 b in the accumulation mechanism 60. Then, the wire 13 between the pair of fixed rollers 61a and 61b is hung from above on the movable roller 63 located above it.

The wire 13 that has passed through the accumulation mechanism 60 is routed so that its direction is changed by the second deflecting pulley 33, and it reaches the winding machine 11 after being wound on the guide pulley 34 of the tension device 31. In the winding machine 11, the wire 13 passing through the guide member 53 is locked to the winding core 12.

In this embodiment, the information related to the core 12 used (specifically, the shape and size information of the core), that is, the cross-sectional shape of the reel portion 12a of the core 12 on which the wire 13 is directly wound, and its The data of the winding width w (FIG. 12) and the data related to the wire diameter d of the wire 13 wound on the winding core 12 are stored in the memory 46 a as the storage unit of the controller 46 via the input device 46 b. Start winding from this state.

When actually winding the winding, the controller 46 drives the winding motor 14 to rotate the winding core 12 at a constant speed, and the rotation angle of the winding core 12 is detected by the rotation angle sensor 16 and fed back to the controller 46.

In addition, with regard to the guide mechanism 51, as shown in FIGS. 12 and 13, the guide member 53 is moved in the rotation axis direction of the winding core 12 by an amount equivalent to the outer diameter of the wire 13 every time the winding core 12 makes one revolution. Thereby, the wire 13 supplied from the wire unwinding mechanism 21 and tensioned by the tension device 31 is wound on the winding core 12 in an orderly arrangement.

In addition, the winding method of the present invention is characterized in that the wire 13 is unwinded from the wire unwinding mechanism 21 at an average winding speed of the wire 13 wound on the rotating core 12, and the wire 13 is unwinded from the wire unwinding mechanism 21. The speed of the unwound wire 13 is decelerated or accelerated so as to be equal to the winding speed of the wire 13 wound on the rotating core 12.

That is, although in actual winding, the core 12 is rotated at the predetermined angular velocity ω stored in the memory 46a, in this embodiment, as shown in FIG. 9(a), the core of the wire 13 is wound The section of the reel portion 12a of 12 is rectangular. In this section, the length from the center of rotation O to the long side is set to a, and the length from the center of rotation O to the short side is set to b. The distance from the center O to the corner is set to c. In addition, when the rotational angular velocity ω of the winding core 12 is maintained at a constant value, as shown in FIG. 9(b), the speed (vertical axis) of the wire 13 wound on the winding core 12 is relative to the rotation of the winding core 12 The angle (horizontal axis) changes in such a way that inflection points of aω, cω, bω, cω, aω, ... are generated.

In this way, although the winding speed of the wire 13 wound on the winding core 12 fluctuates, the cross-sectional shape of the winding core 12 is clear. By multiplying the rotational angular velocity ω of 12, the winding speed of the wire 13 wound on the winding core 12 can be calculated.

In this embodiment, since information related to the cross-sectional shape of the reel portion 12a of the core 12 used for direct winding of the wire 13 (that is, information related to the core 12) is stored in the memory 46a, , The arithmetic circuit 46c in the controller 46 compares the information related to the winding core 12, specifically, the lengths a, b, and c from the rotation center O of the winding core 12 to the parts where the wire 13 is wound. The angular velocity ω of the rotation of the winding core 12 is multiplied to obtain the calculated winding speed as shown by the solid curve in FIG. 9( b ).

In addition, the arithmetic circuit 46c in the controller 46 obtains the calculated coiling speed as shown by the solid line curve in FIG. 9(b), and then calculates that the calculated coiling speed is averaged as shown in FIG. 9(b). ) The average winding speed shown by the dotted line. That is, the calculated average winding speed is the length of the wire 13 wound when the winding core 12 makes one revolution at the calculated winding speed as shown by the solid line curve in FIG. 9(b), divided by its rotation The value derived from the time required for a week.

In addition, the controller 46 controls the winding motor 14 to drive the winding motor 14 and rotate the winding core 12 at a predetermined angular velocity ω, and to use the calculated average winding speed obtained by the calculation circuit 46c. The unwinding motor 26 in the wire unwinding mechanism 21 is controlled in such a way that the wire 13 is supplied from the wire unwinding mechanism 21 at an equal speed.

In addition, the controller 46 rotates the ball screw 66, so that the movable roller 63 and the movable table 67 screwed with the ball screw 66 move up and down in the vertical direction as shown by the long dashed curve in FIG. 9(b), and The wire rod 13 unwound from the wire rod unwinding mechanism 21 at the calculated average winding speed is decelerated or accelerated to calculate the winding speed, and the servo motor 64 in the accumulation mechanism 60 is controlled.

Here, the winding device 10 is provided with an unwinding speed detection sensor 70 that detects the speed of the wire 13 unwinding from the accumulating mechanism 60 toward the tension device 31, and an unwinding speed detection sensor 70 that detects the speed of the wire 13 that passes through the tension device 31. The winding speed detection sensor 80 detects the speed of the wire 13. Thereby, in the case of decelerating or accelerating in the accumulating mechanism 60 in a manner equivalent to the calculated winding speed as shown in FIG. 5(a), the speed of the wire 13 passing through the accumulating mechanism 60 is detected as shown in FIG. The measured unwinding speed shown in (b) is the speed of the wire 13 passing through the tension device 31, and the measured winding speed as shown in FIG. 5(c) is detected.

Here, when the wire 13 is wound around the winding core 12 having a non-circular cross-section such as a rectangle, the winding speed of the wire 13 wound on the winding core 12 changes. Therefore, when the wire 13 is not installed The decelerating or accelerating accumulating mechanism 60 is the same as in the prior art. When the wire 13 is unwinded from the wire unwinding mechanism 21 at a constant speed, as shown by the dotted arrow in FIG. 1, the guide wheel 34 periodically swings, because This swing causes the tension applied to the wire 13 to fluctuate.

In contrast, in the present invention, the wire rod 13 is unwound from the wire rod unwinding mechanism 21 at a calculated average winding speed which is a constant value. In addition, by providing the accumulation mechanism 60, as shown in FIG. 3 or FIG. 4, the wire 13 is periodically decelerated or accelerated so as to be set to a speed equal to the calculated winding speed as shown in FIG. 5(a).

Therefore, as shown in FIG. 5(c), when the winding speed of the wire 13 wound on the winding core 12 is increased, as shown in FIG. 5(b), with the increase, the accumulation mechanism 60 unwinds the wire The wire 13 unwound by the mechanism 21 is accelerated, thereby increasing the speed of the wire 13. Similarly, when the winding speed of the winding core 12 decreases, the accumulation mechanism 60 decelerates the wire 13 unwound from the wire unwinding mechanism 21 in accordance with the decrease, thereby reducing the speed of the wire 13.

In this way, when the speed of the wire 13 unwinding from the wire unwinding mechanism 21 is decelerated or accelerated, and the speed after the actual winding speed of the wire 13 of the winding core 12 is the same, the guide wheel shown by the dashed line in FIG. 1 The periodic oscillation of 34 disappears, and the tension of the wire 13 supplied to the winding core 12 can be kept constant. As a result, a high-quality coil can be manufactured.

In addition, the controller 46 rotates the winding core 12 at a constant speed (that is, rotates at a predetermined angular velocity ω), and moves the guide member 53 in the direction of the rotation axis of the winding core 12, so that the wire 13 is wound around the winding core 12 in an orderly arrangement. When the wire 13 is wound on the winding core 12 in multiple layers, as shown in FIG. 12, when the winding to the first layer of the reel portion 12a is completed, the outer circumference The winding of the second layer is performed. As shown in FIG. 13, when the winding of the second layer is finished, the winding of the third layer is performed on the outer periphery of the wire 13 of the second layer.

In this way, when the wire 13 is wound on the reel portion 12a in multiple layers, as shown in FIGS. The outer layer increases, and when the winding core 12 rotates at a predetermined angular velocity ω, the winding speed of the winding core 12 accelerates toward the outer layer.

Specifically, as shown in FIG. 9, in the case of the first layer, the length from the rotation center O of the winding core 12 to each part where the wire 13 is wound is the outer peripheral shape itself in the cross section of the winding core 12 . As shown in Fig. 10, the length of the second layer from the center of rotation O of the winding core 12 to each part where the wire 13 is wound is as follows: The length after the diameter d. As shown in FIG. 11, the length of the third layer from the center of rotation O of the winding core 12 to each part where the wire 13 is wound is the length obtained by adding the wire diameter d of the wire 13 to the second layer .

The data of the wire diameter d of the wire 13 and the winding width w of the spool portion 12a, which are sequentially added to the shape of the cross section of the winding core 12, are stored in the memory 46a in advance. Therefore, the arithmetic circuit 46c in the controller 46 of FIG. 1 can divide the winding width w by the wire diameter d to calculate the rotation speed required for the neatly arranged winding of each layer.

In addition, in the case of the second layer of winding, as shown in FIG. 10, the length of the second layer of winding from the center of rotation O of the winding core 12 to each part where the wire 13 is wound is obtained. (A+d), (b+d), (c+d). In the case of the third layer of winding, as shown in FIG. 11, the length (a+2d) and (b+2d) from the center of rotation O of the winding core 12 to each part where the wire 13 is wound are obtained as shown in FIG. ), (c+2d). Then, by multiplying the angular velocity ω of the rotating core 12 with the above-mentioned lengths (a+d), (b+d), (c+d), (a+2d), (b+2d), (c+2d), the calculated coiling speed of each layer can be obtained (Figure 10(b), Figure 11(b)).

In addition, the arithmetic circuit 46c in the controller 46 obtains the calculated coiling speed of each layer (10(b), Figure 11(b)), and then calculates the calculated average coiling speed of each layer from the calculated coiling speed, and obtains Calculate the average winding speed as shown by the dot-dash line in Figure 10(b) or Figure 11(b).

In addition, even after the second layer, the controller 46 controls the wire unwinding mechanism to feed the wire 13 from the wire unwinding mechanism 21 at a speed equal to the calculated average winding speed for each layer obtained in this way. 21 in the unwinding motor 26. At the same time, the controller 46 moves the movable roller 63 up and down in the vertical direction as shown by the long dashed curve in Fig. 10(b) or Fig. 11(b) to decelerate or accelerate the wire 13 supplied from the wire unwinding mechanism 21 Even after the second layer, the servo motor 64 in the accumulation mechanism 60 is controlled so as to be equal to the calculated winding speed for each layer obtained by the calculation in this way.

Therefore, even after the second layer, the speed of the wire 13 passing through the accumulation mechanism 60 (unwinding amount) and the winding speed of the wire 13 of the winding core 12 (winding amount) are balanced (that is, balanced) Way to control the amount of unwinding.

Therefore, even after the second layer, the periodic oscillation of the guide wheel 34 in the tension device 31 can be suppressed. Thereby, the elastic member 35 imparts a constant and constant tension to the wire 13 hung on the guide wheel 34 in accordance with the position of the guide wheel 34.

Here, in the actual winding, the controller 46 detects the speed of the wire 13 unwinding toward the tension device 31 by the accumulation mechanism 60 and the speed of the wire 13 toward the winding core 12 by the tension device 31. In addition, the servo motor 64 in the accumulation mechanism 60 is controlled to eliminate the deviation in the time axis direction between the detected speed change state of the actually measured unwinding speed and the speed change state of the actually measured winding speed.

That is, in the present invention, the speed of the wire 13 wound by the winding core 12 and its average winding speed are calculated in advance, and the wire is supplied from the wire unwinding mechanism 21 at a speed equal to the obtained calculated average winding speed. 13, and decelerate or accelerate the wire 13 in the accumulation mechanism 60 to calculate the winding speed. Thereby, as shown in FIG. 5, the speed of the wire 13 does not shift in the time axis direction before and after the tension device 31.

When the rotation speed of the winding core 12 is increased, the deceleration or acceleration of the wire 13 in the accumulation mechanism 60 changes at a faster speed. Therefore, even if the controller 46 controls the servo motor 64 based on the calculated winding speed, the movement of the movable roller 63 does not follow, and the deceleration or acceleration of the wire rod 13 may be delayed. As a result, a deviation occurs between the speed of the wire 13 unwound from the accumulation mechanism 60 toward the tension device 31 and the speed of the wire 13 wound around the core 12 by the tension device 31.

Here, the actual speed of the wire 13 unwinding from the accumulation mechanism 60 toward the tension device 31 is detected by the unwinding speed detection sensor 70, and the actual winding speed of the wire 13 wound by the core 12 is detected by the winding speed The sensor 80 detects. Thereby, the controller 46 always causes the speed change state of the actually measured winding speed determined by the detection output of the winding speed detection sensor 80 and the actual measurement playback speed determined by the detection output of the unwinding speed detection sensor 70. Contrast the state of the speed change of the roll speed. In addition, in order to eliminate the deviation of the detected speed change state of the actual measured unwinding speed and the speed change state of the actual measured winding speed in the time axis direction, the accumulating mechanism 60 implements deceleration or acceleration of the wire 13 .

Specifically, when the actual measured winding speed shown by the solid line in Fig. 6(c) and the actual measured unwinding speed shown by the dashed line in Fig. 6(b) are changed in the time axis direction. When shifting T, the controller 46 obtains the shift T at that time. In addition, the offset T is subtracted from the calculated winding speed shown by the solid line in FIG. 6(a) to obtain the corrected winding speed as shown by the two-dot chain line.

In this regard, the controller 46 of this embodiment is provided to calculate the offset T in the time axis direction of the speed changes of the actual measured winding speed and the actual measured unwinding speed, and subtract the offset T from the calculated winding speed. And obtain the speed correction unit that corrects the winding speed.

In addition, the controller 46 controls the servo motor 64 in the accumulation mechanism 60 along the obtained corrected winding speed indicated by the two-dot chain line in FIG. 6( a ). Then, the controller 46 controls the accumulation mechanism 60 in a state where the calculated winding speed shown by the solid line in FIG. 6(a) is advanced by the offset T. In addition, the actual winding speed of the wire 13 wound by the winding core 12 shown by the solid line in FIG. 6(c) and the speed of the wire 13 that is decelerated or accelerated by the accumulation mechanism 60 toward the tension device 31 are shown in the figure. The solid line in 6(b) is consistent.

Thereby, even when the rotation speed of the winding core 12 is increased and the winding speed to the winding core 12 is changed at a relatively high speed, the accumulation mechanism 60 can decelerate or accelerate to follow the speed change. In this way, the deviation between the actual winding speed of the wire 13 wound by the winding core 12 and the supply amount of the wire 13 supplied to the tension device 31 by deceleration or acceleration by the accumulation mechanism 60 is eliminated, thereby preventing the tension device 31 The guide wheel 34 periodically swings. Thereby, even if the rotation speed of the winding core 12 is increased, the elastic member 35 can impart a constant and constant tension in accordance with the position of the guide wheel 34.

On the other hand, although there is no deviation in the time axis direction between the actual measured coiling speed and the calculated coiling speed's respective speed changes, when the coiling speed itself is offset, that is, if the calculation The winding speed and the actual winding speed of the wire 13 to the winding core 12 are different, and the supply amount of the wire does not match the wire winding amount.

Then, in the tension device 31, the guide wheel 34 that winds the wire 13 is moved along the rail 36, so that the distance between the guide wheel 34 and the winding core 12 is changed, and the position in the Y-axis direction changes for the inconsistent wire 13的量。 The amount. In this way, the difference between the supply amount and the take-up amount is absorbed through the change in the position of the guide roller 34 in the tension device 31. In addition, the movement of the guide wheel 34 is detected by the position sensor 45 and fed back to the controller 46.

Here, when the guide roller 34 moves, the tension applied to the wire 13 gradually changes. Thereby, when a change in the position of the guide wheel 34 is detected through the detection output of the position sensor 45, the controller 46 returns the position of the guide wheel 34 to a predetermined position of the rail 36, for example, approximately in the center. A constant ratio increases or decreases the calculated winding speed, which is the supply amount of the wire rod 13, and obtains the calculated average winding speed based on the corrected winding speed after the increase or decrease. In addition, the controller 46 controls the rotation speed of the unwinding motor 26 based on the calculated average winding speed, and increases or decreases the unwinding speed of the wire 13 in the wire unwinding mechanism 21, thereby making the unwinding speed of the wire 13 It is balanced with the winding speed of the winding core 12.

That is, as shown in Figure 7(a), compared with the calculated winding speed, the actual measured winding speed of the wire 13 to the core 12 is faster, and the guide wheel 34 gradually approaches the winding machine 11, as shown in Figure 7(b) As shown in ), in a manner that the unwinding amount of the wire 13 implemented by the wire unwinding mechanism 21 is increased, the calculated winding speed is increased at a constant ratio, and a corrected winding speed roughly consistent with the actual measured winding speed is obtained. In addition, the corrected average winding speed is calculated based on the corrected winding speed. The corrected average winding speed is also increased by a constant ratio, and the controller 46 controls the unwinding motor 26 in the wire unwinding mechanism 21 in such a way that the corrected average winding speed is increased to unwind the wire 13 to unwind the wire. And the accumulating mechanism 60 decelerates or accelerates the wire 13 so that the actual measured unwinding speed of the wire 13 toward the tension device 31 coincides with the actual measured winding speed as shown in FIG. 7( c ).

On the other hand, as shown in Figure 8 (a), compared with the calculated winding speed, the actual measured winding speed of the wire 13 to the winding core 12 is slower, and the guide wheel 34 gradually moves away from the winding machine 11, as shown in Figure 8 As shown in (b), in a way that the unwinding amount of the wire 13 implemented by the wire unwinding mechanism 21 is reduced, the calculated winding speed is reduced at a constant ratio, and a corrected winding that is roughly consistent with the actual measured winding speed is obtained speed. In addition, the corrected average winding speed is calculated based on the corrected winding speed. The corrected average winding speed is also reduced by a constant ratio, and the controller 46 performs the unwinding motor 26 in the wire unwinding mechanism 21 by unwinding the wire 13 at the reduced corrected average winding speed. It is controlled and the accumulating mechanism 60 decelerates or accelerates the wire 13 so that the measured unwinding speed of the wire 13 toward the tension device 31 coincides with the measured winding speed as shown in FIG. 8( c ).

Thereby, the guide wheel 34 returns to a predetermined position, for example, approximately the center of the rail 36, and the tension applied to the wire 13 returns to a predetermined value.

According to this embodiment, the following effects are achieved.

The winding device 10 of this embodiment includes: a winding core 12; a wire unwinding mechanism 21 that supplies the wire 13 to the winding core 12; and an accumulation mechanism 60 that makes the speed of the wire 13 unwound from the wire unwinding mechanism 21 Decelerate or accelerate; the tension device 31, which applies tension to the wire 13 supplied from the wire unwinding mechanism 21 to the winding core 12; the winding motor 14, which rotates the winding core 12, so that the supply from the wire unwinding mechanism 21, And the wire 13 tensioned by the tension device 31 is wound around the core 12; the controller 46 controls the accumulation mechanism 60 and the wire unwinding mechanism 21, and the controller 46 uses the wire wound on the rotating core 12 The average winding speed of 13 controls the wire unwinding mechanism 21 to unwind the wire 13, and the speed of the wire 13 unwinding from the wire unwinding mechanism 21 is equal to that of the wire 13 wound by the rotating core 12 The accumulation mechanism 60 is controlled so that the winding speed is equal.

In the winding method of this embodiment, the winding core 12 is rotated, so that the wire 13 supplied from the wire unwinding mechanism 21 and tensioned by the tension device 31 is wound on the winding core 12 to be wound on the winding core 12 The average winding speed of the wire 13 of the winding core 12 unwinds the wire 13 from the wire unwinding mechanism 21, and decelerates or accelerates the speed of the wire 13 unwinded from the wire unwinding mechanism 21, so as to rotate with the winding The winding speed of the wire 13 of the winding core 12 is equal.

According to the above structure, although the wire 13 is unwound from the wire unwinding mechanism 21 at a constant speed, the unwinding speed is set as the average winding speed, and it is decelerated or accelerated to be wound on the core 12 afterwards. The winding speed of the wire 13 is equal to the speed. Therefore, even if the tension device 31 includes a member such as the guide wheel 34 that winds the wire 13 and moves by the elastic member 35, it can prevent the member such as the guide wheel 34 from being accompanied by Movement caused by changes in the speed of the wire 13.

As a result, since the tension fluctuation of the wire 13 caused by the movement of the member such as the guide wheel 34 is avoided, even when the speed of the wire 13 wound around the core 12 of different diameter varies significantly It is also possible to keep the tension of the wire 13 wound around the winding core 12 constant.

In addition, in the winding device 10 of the present embodiment, the accumulation mechanism 60 includes a pair of fixed rollers 61a, 61b, which are provided along the moving path of the wire 13 so as to guide the wire 13; and a movable roller 63 for supplying The wire 13 is wound around and is provided between a pair of fixed rollers 61 a and 61 b so as to be movable in a direction crossing the moving path of the wire 13; a servo motor 64 moves the movable roller 63.

In addition, in the winding method of this embodiment, the wire 13 located between a pair of fixed rollers 61a and 61b provided along the moving path of the wire 13 is hung and wound on the movable roller 63, and the movable roller 63 is in contact with each other. The wire 13 moves in the direction where the movement path of the wire 13 intersects.

According to the above structure, the wire 13 located between the pair of fixed rollers 61a and 61b provided along the moving path of the wire 13 is hung on the movable roller 63, and the movable roller 63 is placed in a direction crossing the moving path of the wire 13 The upward movement can decelerate or accelerate the speed of the wire 13 unwinding from the wire unwinding mechanism 21.

In addition, the winding device 10 of the present embodiment further includes: a memory 46a that stores information related to the winding core 12; and an arithmetic circuit 46c that calculates the winding on the winding core based on the information related to the winding core Calculate the winding speed and calculate the average winding speed of the wire 13. The tension device 31 has: a guide wheel 34 for the wire 13 to wind around; an elastic member 35 which applies force to the guide wheel 34, and the controller 46 is based on the calculation The wire unwinding mechanism 21 is controlled by calculating the average winding speed calculated by the circuit 46c to supply the wire 13, and the speed of the wire 13 unwinding from the wire unwinding mechanism 21 is decelerated or increased to become the calculation circuit 46c. The calculated method of calculating the winding speed controls the accumulation mechanism 60.

In addition, in the winding method of the present embodiment, the memory 46a is made to store information related to the winding core 12, and the calculation circuit 46c is used to calculate the calculated winding of the wire 13 wound on the winding core 12 based on the information related to the winding core 12 The take-up speed and the calculated average coiling speed are calculated by the calculation circuit 46c and the wire unwinding mechanism 21 is used to supply the wire 13 to the calculated average coiling speed calculated by the calculation circuit 46c. To decelerate or accelerate the speed of the wire 13 unwinding from the wire unwinding mechanism 21, the tension device 31 has a guide wheel 34 for hanging the wire 13 and an elastic member 35 for urging the guide wheel 34.

According to the above structure, by using the calculated winding speed and the calculated average winding speed stored in the memory 46a in advance, the accumulation mechanism 60 and the wire unwinding mechanism 21 are respectively controlled, so that the wire unwinding from the wire unwinding mechanism 21 The speed after deceleration or acceleration of the speed of 13 is consistent with the actual winding speed of the wire 13 wound by the winding core 12. Therefore, the periodic oscillation of the guide wheel of the tension device disappears, so that the wire supplied to the winding core 12 The tension of 13 is kept constant. As a result, a high-quality coil can be manufactured.

In addition, in the winding device 10 of this embodiment, the accumulating mechanism 60 is provided between the wire unwinding mechanism 21 and the tension device 31, and the accumulating mechanism 60 is provided with an unwinding speed detection sensor 70 that opposes the accumulating mechanism 60 detects the unwinding speed of the wire 13 unwinding toward the tension device 31; the winding speed detection sensor 80 detects the winding speed of the wire 13 toward the core 12 through the tension device 31, and the controller 46 to eliminate the speed change of the actually measured winding speed determined by the detection output of the winding speed detection sensor 80, and the speed change of the actually measured unwinding speed determined by the detection output of the unwinding speed detection sensor 70 The accumulation mechanism 60 is controlled in a manner that the state is shifted in the time axis direction.

In addition, in the winding method of this embodiment, the wire 13 unwinding from the wire unwinding mechanism 21 toward the tension device 31 is accelerated or decelerated, and the unwinding speed of the wire 13 toward the tension device 31 is accelerated or decelerated. , And the winding speed of the wire 13 wound on the winding core 12 by the tension device 31 are detected, and to eliminate the detected speed change state of the measured unwinding speed and the speed change state of the measured winding speed The wire 13 is accelerated or decelerated by means of an offset in the time axis direction.

According to the above configuration, even when the rotation speed of the winding core 12 is increased and the winding speed to the winding core 12 is changed at a faster speed, the accumulation mechanism 60 can decelerate or accelerate to follow the speed change. Therefore, the deviation between the actual winding speed of the wire 13 wound by the winding core 12 and the supply amount of the wire 13 fed to the tension device 31 by decelerating or accelerating by the accumulation mechanism 60 is eliminated, thereby preventing the tension device 31 from being The guide wheel 34 periodically swings. Therefore, even if the rotation speed of the winding core 12 is increased, the elastic member 35 can impart a constant and constant tension in accordance with the position of the guide wheel 34.

Although in the above-mentioned embodiment, the case where the tension device 31 is provided with the guide wheel 34 which is provided so as to be movable along the rail 36 is described, the tension device may also use the elastic member 6 to make the tension arm as shown in FIG. 4 is rotated, and tension is applied to the wire 2 unwound from the guide wheel 5 attached to the front end of the tension arm 4.

Even if it is a tension device having a tension arm 4 as shown in FIG. 15, if the accumulation mechanism is used to decelerate or accelerate the wire unwinding from the wire unwinding mechanism 21 at an average winding speed, and set the wire speed to At a speed equal to the winding speed of the wire rod wound on the winding core, it is also possible to prevent the movement of the guide pulley 5 of the tension device that is caused by the fluctuation in the speed of the wire rod. As a result, since the tension fluctuation of the wire rod accompanying the movement of the guide wheel 5 is avoided, the tension of the wire rod wound around the winding core 12 can be kept constant.

In addition, in the above-mentioned embodiment, the case where the elastic member 35 urging the guide wheel 34 in the tension device 31 is a coil spring is exemplified. However, a fluid pressure cylinder that uses fluid pressure such as air pressure to urge the rod in a direction to sink or protrude may also be used as the elastic member. When such a fluid pressure cylinder is used as an elastic member, when the elastic force is to be changed, the elastic force can be changed relatively easily by changing the fluid pressure of compressed air or the like in the cylinder.

In addition, in the above-mentioned embodiment, the calculation circuit 46c is provided in the controller 46, and the calculation circuit 46c calculates the calculated winding speed or the average winding speed from the information or data stored in the memory 46a. Be explained. However, the arithmetic circuit 46c may not be provided, and the winding speed or average winding speed may be obtained separately from the controller 46 in advance, and the memory 46a may store the calculated winding speed or average winding speed separately provided in this way.

In this case, the controller 46 controls the wire unwinding mechanism 21 to supply the wire 13 in accordance with the calculated average winding speed stored in the memory 46a, and so that the wire 13 unwinded from the wire unwinding mechanism 21 The speed is decelerated or accelerated, and the accumulating mechanism 60 is controlled by the method of calculating the winding speed stored in the memory 46a. Thereby, since frequent movement of the guide wheel 34 is avoided, the tension of the wire 13 wound around the winding core 12 can be kept constant.

In addition, in the above-mentioned embodiment, the case where the accumulation mechanism 60 is provided between the wire unwinding mechanism 21 and the tension device 31 is demonstrated. However, as shown in FIG. 14, the accumulation mechanism 60 may be provided on the downstream side of the tension device 31.

In the case of the winding device 10 shown in FIG. 14, the wire 13 unwound from the wire unwinding mechanism 21 at the average winding speed is given a predetermined tension by the tension device 31 at the average winding speed, and then The speed of the wire 13 after passing through the tension device 31 is decelerated or accelerated so as to be equal to the winding speed of the wire 13 wound on the rotating core 12.

Even with this kind of winding device 10, the speed of the wire 13 passing through the tension device 31 is equal to the winding speed of the wire 13 wound on the rotating core 12, so even if the tension device 31 is equipped with the winding wire 13 In addition, the guide wheel 34 that moves by the elastic member 35 can also prevent the guide wheel 34 from moving along with the change in the speed of the wire 13. As a result, the tension of the wire 13 wound around the winding core 12 can be kept constant.

As mentioned above, although the embodiment of the present invention has been described, the above-mentioned embodiment only shows a part of the application example of the present invention, and does not mean that the technical scope of the present invention is limited to the specific configuration of the above-mentioned embodiment.
