Description

The present invention relates to a winding device that winds a linear material around a spindle.

Conventionally, a device for winding a linear material on a bobbin attached to a spindle to form a coil has been used. As such a device, there is a winding device used for manufacturing a winding used for, for example, a transformer. In such a winding device, a method is adopted in which the electric wire is horizontally moved in the direction of the rotation axis of the bobbin in synchronization with the rotation of the winding frame (hereinafter referred to as a bobbin), and the electric wire is wound uniformly.

Using such a winding device, an operation of arranging an interlayer paper for insulation between layers of electric wires to be aligned and wound may be performed. For example, Patent Document 1 and Patent Document 2 below describe a mechanism for arranging interlayer paper between layers of electric wires to be aligned and wound in a winding device.

Jitsukaisho 62-23434 Gazette Japanese Unexamined Patent Publication No. 11-214238

When performing winding work involving insertion of interlayer paper using a winding device, it is necessary to arrange the interlayer paper every time the wire is wound by the bobbin width (every time it is wound by one layer). be. In this case, it is necessary to slightly overlap the interlayer papers so that the interlayer papers are arranged without gaps over the entire circumference of the bobbin. Further, in order to ensure the quality, it is required to wind the interlayer paper in parallel with the electric wire constituting the winding without causing bending or wrinkling.

The work of inserting such interlayer paper was generally performed manually by an operator. An example of manual work is as follows. That is, when inserting the interlayer paper, the tip portion is fixed to the winding using tape or the like, and then the coil mounting shaft is rotated. Then, while smoothing out the wrinkles of the interlayer paper by hand, the interlayer paper is wrapped so as to cover one round of the coil. However, there is a problem that such manual work is troublesome. Further, since the work is performed manually, there is a problem that the interlayer paper may be inserted or folded in the left-right direction when the interlayer paper is inserted, and the product quality of the winding may vary.

To solve such a problem, for example, Patent Document 2 describes that a tape sticking mechanism for sticking an interlayer paper on an aligned winding surface using a tape is provided to automate the manufacture of windings. However, when such a tape sticking mechanism is provided, there may be a problem that the device becomes complicated or large in size, and it is required to easily manufacture the winding by a method different from this. ing.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a winding device capable of inserting an interlayer paper without the trouble of an operator.

According to an aspect of the present invention to achieve the above object, the winding device is arranged between the spindle, the first delivery mechanism for feeding the strip material to the spindle, and the strand material wound in a layer around the spindle. The second delivery mechanism that feeds the interlayer paper to the spindle, and the linear material that is fed by the first delivery mechanism by rotating the spindle or the interlayer paper that is fed by the second delivery mechanism is wound around the spindle to form a winding body. A contact member having a surface facing the outer peripheral surface of the winding body in a direction parallel to the spindle, and a contact state in which the contact member is in contact with the outer peripheral surface of the winding body are separated from each other. A displacement portion that can switch between the separated state and the separated state is provided, and the displacement portion is configured so that the contact member can be rotated together with the spindle to maintain the contact state while the spindle is rotating.

That is, the urging surface 75b is a surface of the interlayer paper P that comes into contact with the surface opposite to the surface facing the outer peripheral surface of the wound body 20. The regulating surface 75c is a surface on the interlayer paper P side of the flange-shaped portions having a radius larger than that of the urging surface 75b, and regulates the position of the side end portion of the interlayer paper P. The distance between the regulation surfaces 75c of the two rollers is set to be substantially the same as or slightly larger than the width dimension of the interlayer paper P. This prevents skewing of the interlayer paper P and misalignment of the interlayer paper P in the front-rear direction with respect to the wound body 20.

Wrap the material L. In the present embodiment, the predetermined winding state means, for example, a state in which one layer of the linear material L is aligned and wound in the width direction of the winding body 20. When the predetermined winding state is reached, the tip end portion of the interlayer paper P is drawn out on the outer peripheral surface of the winding body 20 by the second delivery mechanism 70. Then, the displacement portion 84 brings the contact member 81 into contact with the vicinity of the tip portion of the outer peripheral surface of the winding body 20, so that the interlayer paper P is fixed to the winding body 20 by the contact member 81. .. In this state, the interlayer paper P is wound around the spindle 11 together with the linear member L while rotating the spindle 11 and the contact member 81 together by the winding portion 10 and the displacement portion 84.

FIG. 4 is a flowchart showing the operation of the winding device 1.

(Step S1) The control unit 2 starts winding the winding body 20.

(Step S2) The control unit 2 winds the linear material L around the main shaft 11 by rotating the main shaft 11 in the normal direction by the winding unit 10 (winding operation). That is, the control unit 2 rotates the spindle 11 while displacing the first delivery mechanism 60 in the traverse direction.

(Step S3) The control unit 2 determines whether or not the number of rotations of the spindle 11 has reached a predetermined amount. The predetermined amount means the number of rotations sufficient to complete the aligned winding of the layers being wound. In other words, the control unit 2 determines whether or not the aligned winding of the layers being wound is completed. If it is determined that the predetermined amount has been reached, the process proceeds to step S4, and if not, the process proceeds to step S8.

(Step S4) The control unit 2 stops the rotation of the spindle 11.

(Step S5) The control unit 2 performs an interlayer paper winding operation. The interlayer paper winding operation will be described later. When the interlayer paper winding operation is performed, the outer peripheral surface of the layer for which the alignment winding is completed is covered with the interlayer paper P, and the alignment winding for the upper layer thereof is started. As will be described later, if there is an abnormality in the insertion of the interlayer paper P in the interlayer paper winding operation, it is detected based on the detection result of the sensor 8.

(Step S6) The control unit 2 determines whether or not the insertion of the interlayer paper P is normally completed. If no abnormality is detected in the insertion of the interlayer paper P based on the detection result of the sensor 8 in the interlayer paper winding operation, the control unit 2 determines that the insertion of the interlayer paper P is completed normally. Then, the process proceeds to step S8. If not, the process proceeds to step S7. That is, in the present embodiment, the control unit 2 changes the winding operation state of the interlayer paper P according to the detection result of the sensor 8. It should be noted that such a determination may be made by setting a flag at the time of executing the interlayer paper winding operation. Further, it can be interpreted that the detection result of the sensor 8 is performed in the interlayer paper winding operation depending on whether or not the detection result is a predetermined result.

(Step S7) If it is not determined that the insertion of the interlayer paper P is normally completed, the control unit 2 performs a notification operation. The notification operation may be, for example, an operation of notifying the operator that the insertion of the interlayer paper P has not been normally completed. For example, various notification methods may be adopted, such as notification by sound output, notification by output of an image to light or a display, notification by stopping the operation of the winding device 1, notification by transmission of information, and the like. In this way, when the insertion of the interlayer paper P is not completed normally, the notification is performed, so that the operator can know to that effect. The operator can perform the corresponding work regarding the fact that the insertion of the interlayer paper P has not been completed normally. In the present embodiment, when the notification operation is performed, a series of winding operations is completed. As a result, the operator can perform operations such as correcting errors and restarting the winding operation.

(Step S8) The control unit 2 determines whether or not the winding of the outermost layer is completed. The determination may be made, for example, by determining whether or not the spindle 11 has rotated by a predetermined number of rotations. If it is determined that the winding is completed, the series of processes is terminated, otherwise the process returns to step S2.

FIG. 5 is a first flowchart showing an interlayer paper winding operation of the winding device 1. FIG. 6 is a second flowchart showing the interlayer paper winding operation of the winding device 1. FIG. 7 is a third flowchart showing the interlayer paper winding operation of the winding device 1.

In the figure, along with each step of the flowchart, the positional relationship seen from the front side of some components is schematically shown. Here, the alternate long and short dash line shows an example of the position of the component displaced in the step before displacement.

When the interlayer paper winding operation is performed, the spindle 11 stops at a predetermined rotation position. In the present embodiment, for example, the spindle 11 is configured to stop in a posture in which the long sides of the winding body 20 are parallel to each other in the vertical direction, but the present invention is not limited to this. The rotation position at which the spindle 11 is stopped is configured to be switched by 180 degrees each time the interlayer paper winding operation is performed. As a result, the overlapping positions of the interlayer papers P of each layer (the positions where the winding start and the winding end overlap) do not overlap at one place, and the entire shape of the winding body 20 can be prevented from becoming distorted. .. The switching of the rotation position of the spindle 11 is not limited to 180 degrees, and the winding start position of each layer may be different by 90 degrees, for example.

(Step S11) The control unit 2 sends the interlayer paper P to a predetermined position. The predetermined position is, for example, on the outer peripheral surface of the winding body 20 and in the vicinity of the portion where the linear material L is being wound, but is not limited to this. Then, the control unit 2 rotationally moves the contact member 81 around the spindle 11 to position it at the first clamp position. Here, the first clamp position is a position slightly upstream of the tip portion P1 of the interlayer paper P. That is, the first clamp position is a position above one short side of the winding body 20 in the present embodiment.

(Step S12) The control unit 2 displaces the contact member 81 toward the rotation axis to bring it into a contact state, and clamps the interlayer paper P and the aligned winding surface of the winding body 20. That is, the contact member 81 is brought into contact with the outer peripheral surface of the winding body 20 to fix the interlayer paper P.

(Step S13) The control unit 2 rotates the contact member 81 so as to follow the spindle 11 in the contact state. As a result, the interlayer paper P is wound around the spindle 11 together with the linear material L in a state where the tip portion P1 is fixed by the contact member 81. Here, in the present embodiment, the second delivery mechanism 70 is such that the upper surface of the interlayer paper P is urged downward by the urging mechanism 75 at a portion slightly upstream of the main shaft 11. As a result, the interlayer paper P is stretched by the urging mechanism 75, and the interlayer paper P is wound while being squeezed.

(Step S14) The control unit 2 rotates the spindle 11 by 180 degrees in the winding direction. At this time, the contact member 81 is rotated in synchronization with the rotation of the spindle 11, and the clamped interlayer paper P is wound around the winding body 20 together with the linear material L. The urging mechanism 75 restrains the drawing direction of the interlayer paper P (prevents skewing) and acts to correct the deflection. As a result, the occurrence of wrinkles on the interlayer paper P is prevented. When the spindle 11 is rotated 180 degrees, the rotation of the spindle 11 and the like is stopped, and the contact member 81 is separated. In this state, since the tip portion P1 of the interlayer paper P is held by the winding body 20 by the linear material L wound by rotating the spindle 11 by 180 degrees, the tip portion of the interlayer paper P already wound. P1 does not shift with respect to the winding body 20.

(Step S15) The control unit 2 rotates and moves the contact member 81 to position it at the second clamp position. The second clamp position is, for example, a position rotated by about 90 degrees in the direction opposite to the winding direction. That is, in the present embodiment, the second clamp position is a position radially away from the long side on the side where the interlayer paper P is arranged.

(Step S16) The control unit 2 displaces the contact member 81 toward the rotation axis to bring it into a contact state, and clamps the interlayer paper P and the linear material L at the second clamp position. Further, the control unit 2 confirms the insertion state of the interlayer paper P by the sensor 8. In other words, the control unit 2 detects whether or not the interlayer paper P is normally inserted based on the detection result of the sensor 8. In the present embodiment, the control unit 2 displaces the sensor 8 upward from a position downwardly away from the spindle 11 to bring it closer to the outer peripheral surface of the winding body 20, and then the detection result of the sensor 8. To confirm. This makes it possible to confirm the inserted state of the interlayer paper P with higher accuracy.

When the control unit 2 detects that the interlayer paper P is not normally inserted, the control unit 2 is configured to interrupt the interlayer paper insertion operation and return to the process of FIG. As a result, the notification operation is performed to the operator, and the operator can correct the insertion state of the interlayer paper P to be appropriate.

(Step S17) The control unit 2 displaces the sensor 8 and returns it to its original position. Then, the control unit 2 rotates the main shaft 11 and the contact member 81 together. At this time, when the rotation angle of the spindle 11 reaches a predetermined rotation angle, the interlayer paper P is cut by the cutting portion 76.

(Step S18) The control unit 2 stops the spindle 11 when the spindle 11 is rotated 90 degrees in the winding direction after clamping at the second clamp position. The control unit 2 releases the clamp of the interlayer paper P with the contact member 81 separated.

(Step S19) The control unit 2 rotates and moves the contact member 81 to position it at the third clamp position. The third clamp position is, for example, a position rotated by about 180 degrees in the direction opposite to the winding direction. That is, in the present embodiment, the third clamp position is a position radially separated from the long side on the side where the interlayer paper P is newly arranged.

(Step S20) The control unit 2 displaces the contact member 81 toward the rotation axis to bring it into a contact state, and clamps the interlayer paper P and the linear material L at the third clamp position.

(Step S21) The control unit 2 rotates the main shaft 11 and the contact member 81 together. As a result, the rear end portion P2 of the interlayer paper P is arranged outside the front end portion P1, and a part of the interlayer paper P overlaps. When the winding of the interlayer paper P is completed, the control unit 2 stops the rotation of the spindle 11 and puts the contact member 81 in a separated state.

(Step S22) The control unit 2 retracts the guide frame 71 of the second delivery mechanism 70 to the upstream side. Then, the rotation of the spindle 11 is restarted, and the linear material L of the next layer is aligned and wound. After that, the process returns to FIG.

As described above, according to the present embodiment, the interlayer paper P can be pressed against the aligned winding surface over the entire circumference of the winding body 20 by the contact member 81. Therefore, the interlayer paper P is fixed to the winding body 20 without sticking the interlayer paper P to the winding body 20 with tape or the like, and the linear material is efficiently wound and the interlayer paper is inserted automatically. Therefore, the interlayer paper P can be inserted properly. The contact member 81 is arranged in parallel with the rotation axis of the main shaft 11, and the position around the rotation axis can be positioned at an arbitrary angle. The abutting member 81 is displaceable toward the rotation axis and can be clamped to the aligned winding surface of the winding body 20 via the interlayer paper P. With such a configuration, it is possible to insert the interlayer paper with a relatively simple configuration without the trouble of an operator. It is possible to prevent wrinkles and slack from occurring in the interlayer paper P, and it is possible to easily manufacture a high-quality wound body 20.
