Description

  The present invention relates to a winding device for winding a winding for an electrical device having a structure in which a multilayer winding is performed and an interlayer paper is inserted between the layer windings.

  In general, a primary winding of a transformer such as a pole transformer has a structure in which multiple layers are wound and an interlayer paper is inserted between layer windings for insulation. As shown in Patent Document 1, a winding device that winds this type of winding has a reel drive having a main shaft that concentrically holds the reel and a rotation drive device that rotationally drives the main shaft. A traverse mechanism disposed between the winding conductor supply source and the reel driving device and traversing the winding conductor wound around the reel with the direction parallel to the axis of the main shaft as the traverse direction. I have.

  Usually, the leg part of the transformer core has a rectangular cross-sectional shape, and therefore, as a winding frame fitted to the leg part, in many cases, the cross-sectional outline shape is rectangular. Used. If the winding frame is rectangular, the winding conductor tends to rise at the long side of the winding frame, and the winding tends to bulge outward. It is preferable to provide means for pressing the winding conductor against the winding frame when it is wound on the winding. Therefore, in the winding apparatus described in Patent Document 1, a winding pressure roller is mounted on the traverse base, and the winding work is advanced while pressing the winding conductor toward the center of the winding frame with the pressure roller. This prevents the winding conductor from lifting from the winding frame or the already wound layer winding.

  The interlayer paper is usually prepared in the form of a roll, and each time one layer winding is wound on the winding frame, the interlayer paper unwound from the roll is supplied to the outer periphery of the layer winding, The paper is wound around the outer periphery of the already wound layer winding, and the winding conductor constituting the next layer winding is wound on the interlayer paper. The interlayer paper is cut to a length longer by a predetermined lapping margin than the circumferential length of the layer winding, and the end portion on the winding start side and the end portion on the winding end side are wrapped at a predetermined lapping margin. Until the outer periphery of the layer winding. By repeating the winding of the layer winding and the winding of the interlayer paper on the layer winding, the multilayer winding having the structure in which the interlayer paper is inserted between the layers is wound.

When the interlayer paper is wound around the outer periphery of the layer winding, it is necessary to align the tip position, and it is necessary to prevent wrinkles from occurring on the interlayer paper wound around the outer periphery of the layer winding. For this reason, in the winding device disclosed in Patent Document 1, when the interlayer paper pressure roller is mounted on the traverse base together with the winding pressure roller, the winding pressure is applied when the interlayer paper is wound around the outer periphery of the layer winding. At the same time the roller is pressed against the outer periphery of the interlayer paper through the winding conductor, the interlayer paper pressure roller is also pressed against the interlayer paper so that the interlayer paper is pressed against the outer periphery of the layer winding by both rollers. .

  In a conventional winding device, in order to wind the interlayer paper around the outer periphery of the layer winding without causing wrinkles in the interlayer paper and with the leading edge of the interlayer paper aligned, one winding is wound. After that, when a new winding frame is set in the winding frame driving device to wind the next winding, the pressure applied to the winding pressure roller and the interlayer paper pressure roller is adjusted to the rigidity of the winding conductor. It was necessary to finely adjust the tensile force acting on the winding conductor. For this reason, not only a skillful technique is required for adjusting the pressurizing force of the winding pressure roller and the interlayer paper pressure roller, but it is inevitable that the adjustment work takes time.

  In addition, when the winding winding work is performed with the adjustment of the pressure applied to the winding pressure roller and interlayer paper pressure roller incomplete, and the leading edge of the interlayer paper is shifted during winding In this case, it was necessary to temporarily stop the winding frame and rework the leading edge position of the interlayer paper. Therefore, the number of man-hours required to wind one winding increases, and the manufacturing cost of the winding increases. I couldn't avoid getting higher.

  Furthermore, in the conventional winding device, every time a new winding is wound, fine adjustment is required, and a situation that requires reworking in the middle of the winding occurs, so adjustment and monitoring of the winding device, It is indispensable to always arrange an operator for correcting the winding state of the interlayer paper, and it is difficult to automate the winding work.

  Here, the operation of the winding device of the present embodiment will be described with reference to FIGS. 1 to 6 and the time chart shown in FIG. In this embodiment, the inner side of the first layer layer winding of the primary winding (the outer periphery of the insulating paper covering the outer periphery of the already wound secondary winding and the first layer layer winding Interlayer paper shall also be inserted. Accordingly, the first interlayer paper is wound around the outer periphery of the insulating paper covering the outer periphery of the secondary winding. At the same time as the winding of the interlayer paper is started, the first layer winding is wound around the outer periphery of the interlayer paper. Start winding work. In the following description, the winding frame 100 and the secondary winding already wound on the outer periphery thereof are treated as a winding frame around which the primary winding is wound.

  In starting the winding work, first, the interlayer paper L is pulled out from the roll 22, and the interlayer paper L is set on the guide plate 312 through the pinch roller 30 and the pressure roller 32. Next, the positions of the end surface guides 313 and 313 on the guide plate 312 are adjusted, and the position of the interlayer paper L is adjusted to the position of the winding. Next, the winding frame on which the secondary winding has been wound is set on the main shaft via the expansion / contraction mechanism, and the preparation work is completed. In this embodiment, the winding frame 100 around which the secondary winding is wound is set on the main shaft, and the primary winding is wound in multiple layers on the secondary winding.

  After performing the above preparation work, the home return work is performed. In this origin return operation, the spindle 100 is rotated to a preset origin position and stopped. In the present embodiment, the rotation angle position of the main shaft when one short side portion of the reel is positioned directly above is set as the origin position of the main shaft.

  After rotating the spindle to the origin position and stopping, the traverse mechanism 2 is moved to the origin position. The origin position of the traverse mechanism 2 is a position where the position of the winding conductor supplied to the winding frame through the traverse mechanism is the winding start position of the first layer winding. Further, the interlayer paper insertion table 302 is moved to the origin position, and the lift table 7 is moved to the origin position. The origin position of the interlayer paper insertion table 302 is set to a position (position shown in FIG. 3) where the pair of press rollers 315 and 315 are sufficiently separated from the winding frame. The origin position of the lifting platform 7 is set to the lower limit position of the lifting platform 7, for example.

  Next, the winding conductor W drawn from the winding conductor stock container 19 is guided to the winding frame side through the guide roller group of the traverse mechanism 2, and the tip of the winding conductor is fixed to the winding frame. Further, the interlayer paper L is fed to the guide device 310 side by the feeding mechanism 24 so that the leading edge position of the interlayer paper L is matched with the leading edge position of the guiding device 310 (initial position of the leading edge of the interlayer paper). . In the winding device of the present embodiment, as will be described later, the required length of the interlayer paper L is supplied to the winding frame side, the interlayer paper is cut by the shear 27, and the guide device 310 is returned to the origin position. After that, the interlayer paper L is fed by the feeding device, and the leading edge of the interlayer paper L is made to coincide with the leading edge position (initial position) of the guide device 310 (initialization of the leading edge position of the interlayer paper). To do. The feeding length of the interlayer paper when the leading edge position of the interlayer paper is initialized is always constant (determined by the configuration of the guide device). When initializing the leading edge position of the interlayer paper, the output of an encoder attached to the pinch roller 30 is counted to feed the interlayer paper when the leading edge position of the interlayer paper L is set to the initial position. Manage the length. In the state in which the leading edge position of the interlayer paper L is initialized, the leading edge portion of the interlayer paper projects forward from the leading edge of the guide plate 312 and is disposed below the roller main body portions 315b and 315b of the pair of pressing rollers 315 and 315. It is in the state that was done.

  When the start button is pressed at time t1 shown in FIG. 8 after making the above preparation, the control device does not urge the line pressure cylinder 218 (with the line pressure roller 217 retracted). In addition, with the pinch roller 30 released (without interleaving the interlayer paper L), the insertion table motor 309 is activated to advance the interlayer paper insertion table 302. As a result, the guide device 310 is advanced, and the guide device 310 is positioned at the initial position during insertion as shown in FIG. Accordingly, the pair of press rollers 315 and 315 and the leading end portion of the interlayer paper L are arranged on the winding frame 101.

  Next, at time t2, the pressure roller 32 is pressed against the pinch roller 30 to pinch the interlayer paper L. At the same time, the pinch roller 30 is rotated to feed the interlayer paper L forward, and the leading edge of the interlayer paper L is already wound around the winding frame. It is sandwiched between the wound winding and the winding conductor W for winding the primary winding.

  Next, at time t 3, the rotation of the pinch roller 30 is stopped to stop the feeding of the interlayer paper, and at the same time, the line pressure cylinder 218 is energized, and the wire pressure roller 217 winds the winding conductor W and the interlayer paper L. At the time t4, the guide plate pressure cylinder 327 is urged and the presser rollers 315 and 315 press the interlayer paper L against the winding frame. At the same time, the spindle motor 105 and the pinch roller 30 are rotated synchronously. Then, the interlayer paper L is wound around the winding frame. As a result, the winding conductor W is wound on the newly supplied interlayer paper L so that the interlayer paper L is fixed to the winding frame. Next, at time t5, the pinch roller 30 is released and its rotation is stopped, and the restriction of the interlayer paper by the interlayer paper feeding device 24 is released. Next, at time t6, the insertion table 302 and the guide device 310 start to retract, and both are retracted to a position before the origin position. At the time t7 when the length of the interlayer paper L already sent to the winding frame side from the shear 27 (interlayer paper cutting device) reaches the required length of the interlayer paper wound around the outer periphery of one layer winding. Stop the spindle motor. At the same time, the pinch roller 30 is pressurized so that the interlayer paper L is restrained and the shear 27 is operated to cut the interlayer paper L. The length of the portion of the interlayer paper that is fed closer to the reel than the shear 27 is measured from the rotation angle of the main shaft detected by the encoder EC1.

  Next, at time t8, the bias of the guide plate pressure cylinder 327 is released to release the pressing of the interlayer paper by the pressing rollers 315 and 315, the spindle motor 105 is rotated at a low speed and the interlayer paper L is wound around the winding frame and the interlayer paper Winding conductor W is wound on the wire. At the time t9 when the interlayer paper L for one turn is wound around the reel, the insertion base and the guide device are moved backward toward the origin position, and the spindle motor is accelerated to rotate synchronously with the traverse mechanism. Wind the layer winding on top.

  In the present embodiment, an interlayer paper having a front end portion placed on one short side portion of the reel is wound around the reel, and the rear end portion is placed on the one short side portion of the reel. The state where the paper is overlapped on the leading end of the disposed interlayer paper is defined as a state where the interlayer paper is wound for one turn, and the length of the interlayer paper for one turn is defined as the required length of the interlayer paper. The required length of one turn of the interlayer paper is a length obtained by adding the length of the short side portion of the layer winding to the outer peripheral length of the layer winding around the interlayer paper. The required length of the interlayer paper becomes longer as the interlayer paper is wound on the outer layer winding.

  The pinch roller 30 is pressurized at time t10 set in the middle of the period in which the winding of the layer winding is in progress, and the interlayer paper L is fed to the winding frame side by the pinch roller to guide the leading edge of the new interlayer paper. The initial state is set at the tip of the device. When the interlayer paper is in the initial state at time t11, the pinch roller is released and its rotation is stopped.

  When the winding of the next layer winding is completed at time t12, the spindle motor is stopped, the urging force of the line pressure cylinder 218 is released, and the line pressure roller 218 is displaced to the retracted position. At this time, the elevator motor 11 is driven to raise the elevator platform. At time t13, when the elevator platform reaches the winding thickness of the winding due to the new layer winding being wound, Stop lifting.

  The operation from time t1 to time t13 in FIG. 8 is repeated to perform a series of layer windings constituting the primary winding on the winding frame and insertion of the interlayer paper between the layer windings. When the winding of the last layer winding is completed, the operation of the winding device is stopped.

  FIG. 9 to FIG. 12 are flowcharts showing the flow of the operation when winding the winding around the winding frame and the control operation of the winding apparatus. In starting the winding work, first, the preparatory work shown in step S1 of FIG. 9 is performed. In this preparatory work, as shown in step S <b> 101 of FIG. 10, the interlayer paper L is pulled out from the roll 22, and the interlayer paper L is set on the guide plate 312 through the pinch roller 30 and the pressure roller 32. In step S102, the positions of the end surface guides 313 and 313 on the guide plate 312 are adjusted, and the position of the interlayer paper is adjusted to the position of the winding. Next, in step S103, the winding frame on which the secondary winding has been wound is set on the main shaft 101 via the expansion / contraction mechanism, and the preparation work is completed. These preparation operations are performed manually. In this embodiment, the primary winding is wound in multiple layers on the secondary winding already wound around the winding frame.

  Next, the process proceeds to step S2 in FIG. 9 to perform the origin return process shown in FIG. In the origin return process shown in FIG. 11, the spindle is rotated to the origin position in step S201, and the traverse mechanism 2 is moved to the origin position in step S202. In step S203, the interlayer paper insertion table 302 is moved to the origin position, and in step S204, the lift table 7 is moved to the origin position. In step S205, the data table stored in the microprocessor memory is updated. These return-to-origin processes may be performed by manually operating the operation switch on the operation panel, or may be automatically performed by a microprocessor.

  As shown in FIG. 13, the data table stored in the memory of the microprocessor includes the total number of turns A of the winding, the number of turns of the layer winding (layer number) B, the initial value C of the interlayer paper cutting, the interlayer A table storing initial setting values of the paper cutting increment value D, the line feed pitch P, the insertion table advance position H, the lifting platform initial value J and the lifting platform increment value K, and the initial setting values as shown in FIG. There is a calculation result table storing the calculated interlayer paper cutting value and layer end value.

  In this embodiment, the rotation speed of the main shaft is expressed in units of “turns”, and the rotation speed of the main shaft that determines the timing for cutting the interlayer paper by shear after the winding of the interlayer paper is started is used as the cutting value. The initial value of the interlayer paper cutting in FIG. 13 is that the leading edge of the interlayer paper L that is first supplied to the reel is the outer periphery of the short side of the reel that is stopped (in this embodiment, the reel is already wound on the reel). In the process of winding the winding conductor and the interlayer paper around the winding frame, the main shaft winds the interlayer paper around the winding frame. This means the number of rotations of the main shaft 101 between the timing at which the rotation for performing the winding of the first layer winding is started and the timing at which the shear 27 cuts the interlayer paper. That is, when the first interlayer paper is wound around the reel, the shear is operated after the main shaft has started rotating for winding the winding conductor and the interlayer paper (from timing t4 in FIG. 8) for 0.12 turns. This means that the interlayer paper is cut.

  In this embodiment, a state where the leading edge of the first interlayer paper is sandwiched between the winding frame and the layer winding body constituting the first layer winding (the leading edge of the interlayer paper is located at the back of the short side of the winding frame). When the main shaft 101 is rotated 0.12 turn from the state of reaching the outermost end of the side, the length of the interlayer paper fed to the reel side from the shear 27 is the required length for one turn of the interlayer paper. The dimensions of each part of the interlayer paper supply device are set so as to be equal to the height.

  Further, the increment value of the interlayer paper cut value in FIG. 13 indicates the increment of the cut value of the interlayer paper that increases every time the layer winding is wound. That is, when winding the second interlayer paper, the shear is operated when the main shaft starts rotating for winding the interlayer paper (from timing t4 in FIG. 8) and rotated 0.12 + 0.05 = 0.17 turns. And cut the interlayer paper. Thereafter, each time the number of layer windings increases, the interlayer paper cut value is increased by 0.05.

  The line feed pitch (1.02 mm) in the table of FIG. 13 indicates the feed pitch of the winding conductor by the traverse mechanism, and the insertion base advance position (100.00 mm) indicates the distance from the insertion base retract position to the advance position. Yes. The initial value of the lifting platform is the distance between the position of the lifting platform and the origin position at the start of the winding work, and the winding work is started with the lifting platform set at a height of 200 mm from the first stroke. It means that. In addition, the elevator base increment (10.0 mm) is raised and lowered when the elevator is raised and lowered in preparation for winding of the next layer winding when the winding of one layer winding is completed (at time t12 in FIG. 8). Amount.

  FIG. 14 shows an interlayer paper cutting value E (n) calculated based on an initial setting value and a layer end value (starting winding one layer winding, and then layering each layer for the nth layer winding. It shows the result of calculating the number of rotations of the spindle until the winding is completed.

  The number N of layer windings to be wound is given by A / B. In this case, the calculation result is rounded to an integer. In this embodiment, since A / B = 660 / 98.50 = 6.70, N = 7.0.

  The interlayer paper cut value E (n) is calculated as follows. That is, E (1) = C when n = 1, E (2) = F (1) + C + D when n = 2, and E (n) = E (n when n> 1. -1) It is set as + C + D.

  The layer end value F (n) is calculated as follows. That is, F (1) = B when n = 1, F (2) = F (1) + B when n = 2, and F (n) = F (n−1) + B when n> 1. To do. The layer end value when winding the Nth layer winding (N = 7th in this embodiment) is F (N) = A. In this example, since the layer winding is wound in seven layers, when n is larger than 7, the calculation result table is initialized with E (n) and F (n) as FFFF.

  After the data table is updated in step S205 in FIG. 11, the line feed pitch and lifting platform initial value data stored in the initial setting value table is sent to the controller in step S206, and the lifting platform is set to the initial position in step S207. Move. Next, in step S208, the winding conductor W is pulled out from the winding drum in the stock container 19, and the drawn winding conductor is guided to the winding frame side via the guide rollers 208, 209 with brakes of the traverse mechanism 2 and the tip portion thereof. Is fixed to the winding start position of the winding frame on which the secondary winding is wound.

  Next, in step S3 of FIG. 9, the process waits for the start button on the operation panel to be pressed, and executes step S4 when the start button is pressed. All processes after step S3 in FIG. 9 are performed by the microprocessor. In step S4 of FIG. 9, the processing shown in FIG. 12 is performed to insert the interlayer paper, roll in the interlayer paper, and cut the interlayer paper.

  In the process shown in FIG. 12, first, in step S301, the motor 309 is driven to move the interlayer paper insertion table 302 to the initial position of the insertion table, the guide plate pressure cylinder is urged, and the press rollers 315 and 315 are moved. The sheet is placed on the reel together with the lower end of the interlayer paper L. Next, in step S302, the main shaft is rotated at a rotational speed V1 lower than the specified rotational speed V2 when winding the winding, and the pinch roller is fed so that the interlayer paper is fed at the same speed as the peripheral speed of the interlayer paper on the winding frame. 30 is rotated synchronously with the main shaft, and the interlayer paper L is drawn out by the specified amount. The extraction of the interlayer paper for the specified opening value is performed until the main shaft rotates 0.12 turns (at time t5) from time t4 in FIG. 8 until the pinch roller is released. Next, in step S303, the line pressure cylinder 218 is energized to press the line pressure roller 217 against the winding conductor and the underlying interlayer paper to sandwich the interlayer paper between the winding conductor and the winding frame. Next, in step S304, the pinch roller is rotated to pull out the interlayer paper, and at the same time, the pinch roller 30 is rotated synchronously with the main shaft so that the drawing speed of the interlayer paper matches the peripheral speed of the winding wound around the winding frame. Let When the number of rotations of the main shaft from the start of winding reaches a specified number of turns, the pinch roller is released and the rotation of the pinch roller is stopped. When the rotational speed of the main shaft from the start of winding becomes equal to the interlayer paper cutting value E (n), the process proceeds to step S306 to stop the main shaft (time t7 in FIG. 8). At this time, the stopped pinch roller is pressed by executing step S307, thereby fixing the interlayer paper L so as not to move, and the interlayer paper is cut by the shear 27. This completes the process of step S4 of FIG.

  After the interlayer paper is cut by the shear 27, the process proceeds to step S5 in FIG. 9 to read the layer end value F (n) from the data table, and in step S6, necessary data is sent to the spindle servo controller. Next, in step S7, the main shaft is rotated at the rotational speed V1, the winding of the layer winding is continued, and the interlayer paper is wound around the winding frame. Thereafter, in step S8, the pressure applied by the guide plate pressure cylinder 327 is released, the interlayer paper insertion table is retracted to the retracted position, and the guide device is retracted to the origin position.

  Next, in step S9, the rotational speed of the main shaft is increased to the specified rotational speed V2 during winding, the main shaft is rotated, and the layer winding is wound. Meanwhile, at time t10 in FIG. 8, the pinch roller is pressurized, and the interlayer paper is fed until the leading edge position of the interlayer paper matches the leading edge position of the guide device. When the rotation speed of the main shaft approaches the layer end value F (n), the rotation speed of the main shaft motor is gradually decreased, and when the rotation speed of the main shaft becomes equal to the layer end value (at time t12 in FIG. 8). ) Stop the spindle motor.

  When the rotational speed of the main shaft motor becomes equal to the layer end value F (n) and the main shaft motor is stopped, step S10 is executed to perform processing for reversing the traverse direction. Next, in step S11, it is determined whether or not the layer end value F (n) is the reset value FFFF. If it is determined that F (n) = FFFF, the process proceeds to step S12, and the layer winding that has not yet been wound is performed. It is determined that there is a line, and the elevator is raised by the elevator increment K. Next, in step S13, the number n indicating the number of the layer winding to be wound is incremented by 1, and the process returns to step S4 to wind the interlayer paper on the already wound layer winding. And winding the next layer winding. When it is determined in step S11 that the layer end value F (n) is the reset value FFFF, the winding work is finished.

  In the case of the above algorithm, the winding frame is stopped every time each layer winding is wound around the winding frame in step S12 of FIG. 9, and the guide device is raised by the winding diameter of the winding diameter. The raising / lowering motor control means for controlling the raising / lowering motor is configured, and the insertion table moving motor control means for controlling the insertion table moving motor 309 to move the guide device forward and displace it to the initial position at the time of insertion by step S301 in FIG. Composed.

  Further, by steps S302 and S303 in FIG. 12, a new interlayer paper is supplied onto the already wound layer winding in a state where the guide device is displaced to the initial position at the time of insertion, and the leading edge of the new interlayer paper is obtained. The interlayer paper feeding device control means for controlling the interlayer paper feeding device is configured so as to sandwich the wire between the winding conductor forming the next layer winding and the already wound layer winding, and the steps of FIG. In S304 to S307, the guide device is urged to rotate in one direction while being held at the initial position at the time of insertion, so that the new interlayer paper is wound with the press roller pressed against the reel side. Rotate the frame to wind the new interlayer paper around the outer periphery of the winding frame while following the guide device along the outer periphery of the winding frame. Wound around the circumference of one layer winding Interlayer paper winding control means for controlling the reel driving device, guide device urging mechanism and interlayer paper cutting device to stop the reel and cut the interlayer paper when the required length of the interleaf is reached Is done.

  Further, in step S8 of FIG. 9, after the new interlayer paper is fixed on the already wound layer winding, the guide device is retracted to the origin position and rotated in the other direction. Guide device return control means for controlling the movable table motor 309 and the guide device urging mechanism so as to perform the operation of separating the roller from the winding frame is configured, and in step S9 of FIG. 9, the layer winding is wound. The winding spindle motor control means for controlling the spindle motor and the interlayer paper so as to feed the interlayer paper until the leading edge position of the interlayer paper is set to the initial position in preparation for winding of the next layer winding. Interlayer paper tip position initialization means for controlling the feeding device is configured.

  In the above embodiment, the management of the feeding length of the interlayer paper when initializing the leading edge position of the interlayer paper is performed by counting the output pulses of the encoder attached to the rotating shaft of the pinch roller. The feeding length of the interlayer paper when the paper tip position is initialized is constant, and the time for the interlayer paper feeding device to feed the interlayer paper to initialize the leading edge position of the interlayer paper is constant. Therefore, the interlayer paper is used for initializing the position of the leading edge of the interlayer paper from the number of rotations (turns) of the main shaft when the reel is rotated at a constant rotational speed V2 in order to wind the main shaft. You can also manage the feed length. That is, the number of spindle turns (number of turns from the start of winding) that determines the timing to start feeding to initialize the leading edge position of the interlayer paper, and the number of spindle turns that determine the timing to stop feeding Are stored in the data table as the feed start value at the initialization of the interlayer paper and the feed stop value at the initialization of the interlayer paper, respectively, and the number of turns of the spindle detected by the encoder EC1 attached to the rotary shaft of the spindle motor Presses the pinch roller to feed the interlayer paper when it matches the feed start value at the initialization of the interlayer paper, and the detected number of spindle turns matches the feed stop value at the initialization of the interlayer paper Sometimes the pinch roller may be released to stop feeding the interlayer paper.

  As described above, in the present invention, when a new interlayer paper is supplied onto the layer winding wound on the winding frame and the interlayer paper is wound around the outer periphery of the layer winding, the new interlayer paper is Because both ends in the width direction of the new interlayer paper are pressed against the winding frame by a pair of pressing rollers until it is fixed to the winding frame by the winding conductor constituting the layer winding. When the new interlayer paper is wound around the outer periphery of the winding frame or the outer periphery of the already wound layer winding, the position of the interlayer paper can be prevented from shifting. Accordingly, the winding work can be performed without causing a shift in the leading end position of the interlayer paper or causing the wrinkles in the interlayer paper. There is no need to rework the paper winding state. In addition, since it is not necessary to perform complicated adjustment every time a new winding is wound, the winding operation can be easily automated.

  As in the above embodiment, both end positions in the width direction of the interlayer paper are regulated by the pair of end surface guides 313 and 313, and the interlayer paper is formed between the pair of end surface guides by the interlayer paper pressing plates 316 and 316. On the other hand, if the paper is supplied to the reel while being lightly pressed, wrinkles on the interlayer paper can be reliably prevented. However, the present invention is not limited to the above configuration, and the interlayer paper pressing plate can be omitted depending on circumstances.

  As in the above embodiment, in the process of starting the winding of the interlayer paper around the outer periphery of the already wound layer winding, the interlayer paper feeding device 24 feeds the interlayer paper while the winding frame rotates at a set angle. If the feed speed is controlled to be equal to the peripheral speed of the layer winding on the winding frame, tension is not applied to the interlayer paper when winding the interlayer paper, and the leading edge position of the interlayer paper deviates from the normal position. Can be prevented.

  As in the above embodiment, when the guide device is biased to rotate in one direction at the initial position at the time of insertion, the pair of presser rollers is a hooked roller. Is configured to guide the reel in opposition from the axial direction to both end surfaces in the axial direction of the reel and / or both end surfaces in the width direction of the interlayer paper already wound on the reel. Since the interlayer paper can be supplied onto the layer winding wound around the winding frame in a state where the winding frame is accurately positioned with respect to the guide device, the positional deviation of the interlayer paper can be reliably prevented.

  However, the present invention is not limited to the case where the presser portion is configured as described above. For example, instead of the presser roller used in the above-described embodiment, a presser roller having no ridge may be used.

  Further, the pair of presser portions does not necessarily need to be configured by rollers that are rotatably supported. For example, as shown in FIG. 15, a cylindrical main body 315b 'and a flange formed at the end of the main body 315b' 315a ′, and a pair of cylindrical members 315 ′ and 315 ′ (only one cylindrical member 315 ′ is shown in FIG. 15) fixed to the ends of the end surface guides 313 and 313. It can also be a pressing part. In the example shown in FIG. 15, the flange 135a ′ can be omitted. As described above, when the presser portion is formed of a fixed member, the presser portion is preferably formed of a material having good slip such as Teflon (trade name).

  Further, as shown in FIGS. 16A and 16B, the surface that contacts the winding frame 100 (or the winding wound on the winding frame) is a smooth outer peripheral surface such as a cylindrical surface. A holding member 350b having a main body portion 350b and a flange portion 350a formed integrally with the end portion of the main body portion is integrally formed at the tip of each end surface guide 313, and each of the pair of end surface guides 313, 313 is formed. The presser members 350b and 350b formed at the tip of each of them may be a pair of presser portions. In this case, it is preferable that the end surface guides 313 and 313 are made of a material having good slip such as Teflon (trade name).

  Further, as shown in FIG. 17, a spring 360 bent so that the surface abutting on the winding frame is a smoothly curved surface is screwed to the tip of each end surface guide 313, and a pair of end surface guides 313, 313 is formed. The springs 360 and 360 attached to the respective tips of 313 may be used as a pair of presser portions.

  In the above embodiment, the case where the primary winding is wound in a multilayer on the winding frame on which the secondary winding has already been taken is taken as an example, but also in the case where the winding is wound directly on the winding frame. Of course, the present invention can be applied.
