Description

Winding device of filigree

As a technique regarding the winding apparatus which winds up an ancestor material, the winding machine which winds the coil of an electric motor is disclosed by Unexamined-Japanese-Patent No. 3-159541, for example. This winding machine is provided with a drum with one end of the drum and the other end freely supported, and the tension is applied to the electric wire by winding the wire released from the wire drum to the drum and tensioning the courtyard of the support by the air cylinder. We adopt technique to say.

In particular, Japanese Patent Laid-Open Nos. 7-2203636 and 63-6731 disclose a winding machine of a deflection yoke (deflection coil) for use in televisions and the like. In the case of the deflection yoke, the filigree is wound in a concentrically complex path along the groove of the trumpet-shaped bobbin.

Moreover, the conventional winding apparatus which winds up the spool material by weight is wound up the spool material of predetermined weight by rotating the winder spool inserted in the shaft, and unwinding a real winder and winding this by the predetermined number of windings. .

However, in the winding machine of Japanese Patent Laid-Open No. 3-159541, a tension adding mechanism having a structure for tensioning a support post by an external air cylinder is used, and since the inertia is large, it sufficiently absorbs the tension fluctuation of the electric wire and provides a constant tension. Is difficult to maintain. Moreover, in such a winding machine, since a resonance phenomenon occurs in a specific tension fluctuation period depending on the characteristics of the air cylinder, a state in which the tension control does not function occurs.

Further, in the winding technology of the deflection yoke described in Japanese Patent Application Laid-Open Publication No. Hei 7-2203636 or 63-6731, the tension fluctuation of the filigree material during winding is considerably larger and tension due to the winding of the filigree material in a concentric manner along a complicated path. Due to the fluctuation, the stiffness of the filigree material is locally loosened. In this way, the coiling material meanders at the portion where the coiling material is loosely wound, so that a good winding state cannot be obtained. Since the deflection yoke of the deflection yoke depends on the winding state of the filigree, when the tension fluctuation occurs during winding, the filigree meanders and twists in the magnetic field generated from the deflection yoke, thereby reducing the deflection degree.

Furthermore, in winding devices for winding heavy-duty lumber, when winding a thread winder or the like having a small diameter and susceptible to breakage, the thread winder may be stretched during winding or the irregularities may be mixed in the thread winder. For this reason, the seal winder wound on the winder spool before winding is not constant in weight (weight ratio) of the unit length depending on the part. Therefore, in the conventional winding apparatus which manages the winding number of a thread winder, since it was not possible to wind the thread winder of the target weight correctly, the winding weight must be adjusted by manual operation after winding, and the work efficiency of a winding operation becomes Was bad.

EMBODIMENT OF THE INVENTION Hereinafter, the 1st-4th embodiment is demonstrated with reference to FIGS.

[First Embodiment]

1 is a winding flow diagram illustrating a configuration of a yarn winder winding device according to a first embodiment. In Fig. 1, reference numeral 1 denotes a winder spool, which is wound around the winder 2 (fiber) and inserted into the shaft of the unwinding motor 3. The winder spool 1 (storage means) and the releasing motor 3 form a releasing means. The thread winder 2 is a thread winder with a diameter of about 0.2 mm and very thin.

The loosening motor 3 is applied to a control sub-motor, for example, an AC sub-motor, a DC sub-motor, a vector inverter motor, or the like having good speed responsiveness, and wound around the winder spool 1 in accordance with the spindle motor for winding described later. Loosen the thread winder 2. When the AC sub-motor is used as the unwinding motor 3, performance deterioration is small even after long-term use, and the maintainability is improved. Moreover, the feedback unit 3a which detects the rotation speed is provided in the shaft of this unwinding motor 3. As shown in FIG.

Reference numeral 4 is a torque actuator, 4a is an arm, 4b is an arm position detecting device (position detecting means), and each of these portions forms a tension detecting means. The torque actuator 4 is a DC sub-motor, an AC sub-motor or a low inertia vector inverter motor, a coreless motor, or the like, which has excellent response and low inertia, and the axis of the arm position detecting device 4b and the real winder 2 is applied to the shaft. Arm 4a is provided as a means.

The arm 4a is formed of a material having a low specific gravity to suppress inertia, and is mounted to be perpendicular to the axis of the torque actuator 4, and a pair of freely rotatable pulleys 4a ₁ and 4a ₂ are provided at both ends. In this pulley 4a ₁ , 4a ₂ , the thread winder 2 is caught and rotated in the Z phase so as to be the axis object with respect to the axis of the arm 4a. The arm position detecting device 4b is applied with a potentiometer, a rotary encoder, or the like, and detects the rotational displacement of the arm 4a.

In addition, the above-mentioned fastening means may be comprised as shown in FIG. That is, a plurality of rotatable pulleys 10a are provided on one side of the disk 10 centered on the shaft of the torque actuator 4 at regular intervals along the periphery, and two of the pulleys 10a are diagonally opposed to each other and the thread winder Walk 2 over Z. When a plurality of pulleys 10a are provided in this way, when the disc 10 rotates in the direction of the arrow X2, the thread winder 2 is wound around the adjacent pulley 10a, so that the direction of the thread winder 2 is always tangential to the pulley 10a. Can be maintained and prevent the extreme winding of the thread winder 2.

Numeral 5 is a tubular winding nozzle, the axis direction of bobbin 6, that is, the arrow Y1. It is made to reciprocate in the Y2 direction. The bobbin 6 is mounted on the shaft of the spindle motor 7 and winds up the seal winder 2 by operating the spindle motor 7. This spindle motor 7 and bobbin 6 form a winding means. The spindle motor 7 is equipped with a speed control motor such as a DC submotor or an AC submotor having excellent responsiveness, and a feedback unit 7a for detecting the rotational speed is attached to the shaft. In addition, the code | symbol 8, 9 is a guide roll which winds the thread winder 2, and changes a conveyance direction.

Next, with reference to FIG. 3, the control structure of the said winder winding apparatus is demonstrated.

In this figure, reference numeral 11 denotes an operation panel, 12 an indicator, 13 a winding control device, 14, 15.17 a driver, and 16 a tension control device.

Various operation buttons are provided in the operation panel 11, and various operation information, such as the start of winding-up and the weight by which the bobbin 6 is wound by the bobbin 6, is input. The indicator 12 is a liquid crystal display, for example, and displays the operation state of the said thread winder winding device, etc.

The winding control device 13 is constituted by an MPU (microprocessor) 13a, a ROM (read only memory) 13b, a RAM (read / write memory) 13c, and an interface not shown. In ROM 13b, a control program related to the control of the whole winder winding device is stored. The RAM 13c stores various calculation results when the MPU 13a performs control processing in accordance with the control program. The MPU 13a performs processing in accordance with the control program based on various operation information input from the operation panel 11, and operates the driver 14 for driving the releasing motor 3, the driver 15 for driving the spindle motor 7, and the tension control device 16. To control.

The driver 14 drives the unwinding motor 3 and the feedback unit 3a detects the rotational state of the unwinding motor 3 and feeds it back to the winding control device 13. The driver 15 drives the spindle motor 7 and the feedback unit 7a detects the rotational state of the spindle motor 7 and feeds it back to the winding control device 13. The tension control device 6 controls the driver 17 so that a constant current flows in the torque actuator 4, and outputs a feedback signal input from the arm position detection device 4b to the winding control device 13.

Among the components described above, the tension adjusting means is constituted by the torque actuator 4, the arm 4a (hanging means), the arm position detecting device 4b, the winding control device 13, the tension control device 16, and the like.

Next, the operation of the seal winder winding device will be described. When the winding weight is input from the operation panel 11 and the winding of the actual winder 2 is instructed, the winding control device 13 sequentially raises the speed of the spindle motor 7 until the speed reaches the predetermined speed value V1. In addition, in accordance with the rotation of the spindle motor 7, the speed of the unwinding motor 3 is also sequentially increased until the speed value V1 is reached.

In this way, since the unwinding motor 3 is controlled in accordance with the rotation of the spindle motor 7, it is possible to greatly suppress the transient tension fluctuation applied to the thread winder 2 at the start of winding and to prevent the thread winder 2 from stretching. It is possible. In addition, the total rotation speed of the spindle motor 7 from the start of winding is calculated by the counter provided in the inside of the winding control apparatus 13, and the winding weight of the real winder 2 is judged based on this calculated value.

When the winding of the real winder 2 is started in this way, the tension of the real winder 2 during the winding period is controlled as follows. That is, if the tension of the seal winder 2 that rotates on the arm 4a varies, the arm 4a is displaced in the direction of the arrow X2 (see Fig. 1), and the displacement amount is detected by the arm displacement detecting device 4b and fed back to the tension control device 16. do. The tension control device 16 outputs the displacement amount of this arm 4a to the winding control device 13. Thus, the winding control device 13 outputs an instruction to the driver 14 to change the rotational speed of the unwinding motor 3 so that the displacement of the arm 4a is returned to its original state. According to this change instruction, the driver 14 changes the drive current supplied to the releasing motor 3. As a result, the unwinding speed of the seal winder 2 is changed and the displacement of the arm 4a returns to the normal position, and the tension of the seal winder 2 is returned to the prescribed tension.

Here, since the low inertia motor with excellent response performance is applied to the unlocking motor 3 as described above, it is possible to perform the adjustment of the small loosening speed at high speed. In addition, since a low inertia motor having excellent response performance is also applied to the torque actuator 4, it is possible to detect minute tension fluctuations of the real winder 2 at high speed. Therefore, the fluctuations in the tension applied to the real winder 2 during winding are good in followability and are suppressed against the slight fluctuation, and the real winder 2 is wound around the bobbin 6 with a constant tension.

Therefore, when the spindle motor 7 rotates by the predetermined number of times, the speed of the spindle motor 7 is gradually decelerated by the winding control device 13, and the spindle motor 7 is stopped when the actual winder 2 is wound by the predetermined number of turns. At this time, the unwinding motor 3 is gradually decelerated in accordance with the rotation of the spindle motor 7 as in the start of winding.

Also in the case where the fastening means shown in Fig. 2 is used, the displacement in the direction of the arrow X2 of the disc 10 in response to the tension variation of the seal winder 2 is fed back so that the tension of the seal winder 2 is kept constant. In addition, although this embodiment demonstrated the case where the real winder was wound as a filigree material, this invention is not limited to this, It is effective for the winding of the fragile filigree material which is not limited to a real winder.

Furthermore, the viscous resistance acting on the real winder 2 changes depending on the winding speed of the real winder 2, that is, the conveying speed. Therefore, the feed speed of the real winder 2 is detected based on the output of the feedback unit 3a or the feedback unit 7a, and the change in tension of the winder 2 based on the viscous resistance is calculated by ### proportional to the feed speed, It is effective to adjust the value of the current supplied to the torque actuator 4 based on this calculated value.

Moreover, as mentioned above, although the unwinding speed is controlled so that the unwinding motor 3 may be matched with the rotation of the spindle motor 7, when unwinding at a high acceleration, the unwinding motor 3 is unstable to the unwinding speed of the spindle motor 7 or the displacement speed of the arm 4a. There is a case that cannot be followed. In response to such a situation, it is detected from the respective outputs of the feedback units 3a, 7a and the arm position detecting device 4b that the unwinding motor 3 cannot follow the winding speed of the spindle motor 7 or the displacement speed of the arm 4a. It is available to adjust the unwinding speed.

Second Embodiment

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. In this embodiment, the present invention is applied to the winding yoke of the deflection yoke shown in Japanese Patent Application Laid-Open No. H7-2203636, and the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. In this embodiment, as the filigree, a stranded wire 2 'obtained by twisting a plurality of conductive wires of thin diameter (for example, 0.25 mm in diameter) on which an enamel or the like is applied is applied.

4 is a perspective view showing an example of the configuration of a funnel bobbin (winding means) constituting a deflection yoke. As shown in this figure, the funnel-shaped bobbin 20 has two flange-shaped bobbin bodies 20a and two flanges parallel to each other along the edge at the upper portion (opening side) of the bobbin body 20a and perpendicular to the central axis L of the bobbin body 20a. 20b and 20c and two flanges 20d and 20e which are parallel to each other along the edge at the lower part (neck side) of the bobbin main body 20a and installed perpendicular to the central axis L of the bobbin main body 20a. A plurality of nodules 20b1 are provided on the flange 20b by winding stranded wire 2 ', and a plurality of nodules 20e1 are similarly provided on the flange 20e.

It is a top view which shows the structure of the winding apparatus of this embodiment which wound the twisted pair 2 'around the said funnel type bobbin 20. In this figure, the funnel-type bobbin 20 is fixed to the substrate 22 by the bobbin support mechanism 21 such that the central axis L coincides with X-X '. Therefore, the twisted pair 2 'is wound up sequentially by the operation of the nozzle mechanism 23 and the hook mechanism 24. FIG. In this figure, the left and right directions of the ground are the X-axis of three-dimensional coordinates, the vertical direction of the ground is the Y-axis, and the vertical direction of the ground is the Z-axis.

The nozzle mechanism 23 rotates the nozzles 23a and 23b for feeding the stranded wire 2 'wound around the funnel bobbin 20 from the distal end portion, and the nozzles 23a and 23b are rotated by an angle θ1 about the X1 axis or X1' axis parallel to the X axis. The stranded wire 2 'attached to the tip of the XYZ drive mechanism 23d for moving the θ drive mechanism 23c, the nozzles 23a, 23b in the three-dimensional coordinate space, and the cylinder 23e and wound with a funnel bobbin 20 is terminated with the nozzle 23a, It consists of the cutter 23f which cut | disconnects from 23b.

The hook mechanism 24 moves the hooks 24a and 24b in a three-dimensional coordinate space and simultaneously rotates the hook XYZ θ driving mechanism 24c to rotate the angle θ2 or the angle θ2 'about the X2 axis or the X2' axis, and starts winding the twisted pair 2 '. The winding start clamp 24d which binds the stranded wire 2 'to the tip of the cylinder 24e which can be moved in the three-dimensional coordinate space by the hook XYZ θ drive mechanism 24c, and the stranded wire 2' at the start of winding the stranded wire 2 '. It consists of a winding start hook 24f which guides to the predetermined winding starting position of the funnel type bobbin 20.

In addition, the control structure of this embodiment is a structure which removed the bobbin 6, the spindle motor 7, the feedback unit 7a, and the driver 15 in the block diagram shown in the said FIG.

In the funnel-shaped bobbin 20 formed as described above, the fibrous material has an arrow a (passed through the inside of the bobbin body 20a) → arrow b → arrow c → arrow d → arrow e (passed through the inside of the bobbin body 20a) → arrow as shown in FIG. In order of f → arrow g → arrow h → arrow a, that is, it winds asymmetrically along a complicated path. For example, the nozzle 23a is moved to the hook mechanism 24 side of the X axis so that the leading end of the stranded wire 2 'is towed to the hook 24a, the hook 24a is moved to wind the stranded wire 2' to the groove between the flanges 20d and 20e, and then The nozzle 23a is moved above the nozzle θ drive mechanism 23c side and the flanges 20b and 20c, and the stranded wire 2 'is wound around the groove between the flanges 20b and 20c inside the bobbin main body 20a.

In the winding of the stranded wire 2 'as described above, the nozzle 23a is moved in the three-dimensional coordinate space, and the unwinding speed of the stranded wire 2' wound around the funnel bobbin 20 passing through the nozzle 23a is moved by the nozzle 23a. The speed fluctuates greatly. As a result, the tension applied to the stranded wire 2 'greatly changes during winding, and the stranded wire 2' is locally wound loosely.

However, since the torque actuator 4 driven in accordance with the tension control device 16 described above is constituted by a DC sub-motor, an AC sub-motor, a low-inertia vector inverter motor, a coreless motor, or the like having excellent response performance and low inertia, It is possible to absorb 2 'tension variations. As a result, the phenomenon that the stranded wire 2 'meanders due to the tension fluctuation is suppressed, and the stranded wire 2' is wound around the surface of the funnel-type bobbin 20 squarely.

In addition, the present invention can be applied not only to the funnel-type bobbin 20, but also to bobbins in which vertical coils and horizontal coils are disclosed.

[Third Embodiment]

Next, a third embodiment of the present invention will be described with reference to FIGS. 6 and 7. The same code | symbol is attached | subjected to the structural member similar to the said 1st Embodiment and 2nd Embodiment, and the description is abbreviate | omitted.

In the second embodiment, the winding device for forming the deflection yoke by winding the filigree material to the saddle-shaped funnel bobbin is described. However, the winding device of the present embodiment is a filigree material. A wire is used and the bobbin is not used, but the winding is rotated by rotating the winding between the saddle-shaped poles formed in accordance with the winding of the male and the female. By fusing the turned filigree to form a deflection yoke. The self-fusion wire is, for example, a conductive wire coated with a coating material that dissolves by heating, and twisted wires of 2 " are formed.

6 is a diagram illustrating a configuration of this embodiment. In this figure, the code | symbol 30 is a winding-up part (winding means), and is formed by the lower metal mold | die 31 and the upper metal mold | die 32. As shown in FIG. For example, the lower die 31 is fixed to the apparatus main body (not shown), and the upper die 32 is supported by the apparatus main body freely up and down. Therefore, when the upper die 32 is lowered and fitted to the lower die 31, a saddle-shaped gap is formed between the lower die 31 and the upper die 32, and a twisted pair 2 "is inserted and wound around this gap.

7 is a perspective view illustrating a state in which the upper mold 32 is spaced apart from the lower mold 31. As shown in this figure, the upper die 32 is formed of a counter seat 32a, which is a flat plate, and an upper winding portion 32b provided on the lower surface of the counter seat 32a, and wire rod guides 32c and 32d. The upper winding portion 32b is formed of a upper winding surface 32b1 formed in a saddle shape, a connecting portion 32b2 provided almost at the center of the upper winding surface 32b1, a connecting hole 32b3 formed in the connecting portion 32b2, and the like.

On the other hand, the lower die 31 is formed of the lower base 31a, which is a flat plate, and the lower winding part 31b and the wire rod guides 31c, 31d provided on the upper surface of the lower base 31a. The lower winding portion 31b is formed of a lower winding surface 31b1 formed to be fitted to the upper winding surface 32b1 of the upper winding portion 32b and a projection portion 31b2 in which a tip is inserted into the connecting hole 32b3. The wire guides 31c, 31d, 32c, and 32d respectively provided on the lower mold 31 and the upper mold 32 are provided to facilitate the introduction of stranded wire 2 "into the gap between the lower mold 31 and the upper mold 32 at the time of winding. .

In the block diagram shown in FIG. 3, the control configuration of the present embodiment has a configuration in which the winding unit 30 is attached to the spindle motor 7 instead of the bobbin 6. In this case, the winding unit 30 is a heavy object in comparison with the bobbin 6, and a larger torque is applied to the spindle motor 7.

According to the winding device thus formed, the upper die 32 is lowered and fitted in a state where a stranded wire 2 "is inserted between the upper winding face 32b1 and the lower winding face 31b1. Here, the upper winding face 32b1 and the lower winding face 31b1 are spaced at a constant distance. They are disposed to face each other, and a saddle-shaped gap is formed by the upper winding face 32b1 and the lower winding face 31b1. Further, the distal end portion of the stranded wire 2 "is held by graph means (not shown) provided on the lower pedestal 31a.

In this state, if the winding part 30, that is, the upper mold 32 and the lower mold 31 rotate in the horizontal plane, the stranded wire 2 "enters between the lower winding part 31b and the upper winding part 32b to form a saddle shape along the gap between the connecting part 32b2. Thus, by energizing the wound wire 2 "wound in this way, the surface of the said twisted wire 2" is fused, and the saddle-shaped deflection yoke is formed.

Here, the twisted pair 2 "is intruded and wound between the lower winding part 31b and the upper winding part 32b. At this time, since the twisted pair 2" is wound up and down along a shape of the upper winding face 32b1 and the lower winding face 31b1, it is wound around a non-concentric circle. The speed fluctuates greatly. Therefore, the stranded wire 2 "is wound around the winding-up part 30 with large tension fluctuations.

However, the torque actuator 4 driven by the tension control device 16 described above is constituted by a DC sub-motor, an AC sub-motor, a low-inertia vector inverter motor, a coreless motor, or the like having a low inertia with excellent response performance. It is possible to easily absorb the tension fluctuations of the wire. As a result, the phenomenon in which the twisted wire 2 "meanders or slowly winds up due to the tension fluctuation is suppressed, and the twisted wire 2" is wound with a constant tension about the connection part 32b2. Will turn.

The deflection yoke described in the second and third embodiments deflects an electron beam by a magnetic field in a CRT or the like, and is a magnetic field generated when twisted wire 2 '(or twisted wire 2 ") is locally meandered or slowly wound. However, according to the winding device of the present invention, the winding tension of the wire rod can be kept constant even when the wire rod is wound in a complicated shape, and the deflection yoke of high quality with good deflection accuracy is possible. It is possible to prepare.

Fourth Embodiment

Next, with reference to FIGS. 8-10, the 4th Embodiment of this invention is described. The same code | symbol is attached | subjected to the structural member same as the structural member demonstrated in 3rd Embodiment from the said 1st Embodiment, and the description is abbreviate | omitted.

In this figure, reference numeral 1 'denotes a winder spool wound by a large amount of yarn winders 2, and is placed on a weigh scale 40 to measure the weight thereof. On the shaft of the unwinding motor 3, a feedback unit 3a for detecting the rotational speed and a roller 3b for winding and conveying the seal winder 2 are attached. Further, the guide rollers 41A and 41B are for winding the thread winder 2 to the roller 3b by a predetermined winding angle. In this embodiment, the release means is formed by the winder spool 1 ', the release motor 3, the feedback unit 3a, the roller 3b, and the guide rollers 41A, 41B.

Next, with reference to FIG. 9, the control structure of this embodiment is demonstrated.

In the present embodiment, the operation panel 11 'is configured to input the total winding weight (winding target weight) of the seal winder 2, while the indicator 12' is the winding target weight or actually wound of the wound winder 2 It is configured to indicate the winding weight. That is, part of the ROM 13b included in the winding control device 13 'is composed of an EEPROM capable of electrical erasing / writing input, and this EEPROM includes a standard value of the weight change amount per unit time when the actual winder 2 is wound (reference weight) The amount of change) is stored in a table form for each of the winding target values. The detail of this reference weight change amount is mentioned later.

Next, operation | movement of this thread winder winding apparatus comprised in this way is demonstrated in detail. First, as a winding target value of the real winder 2 from the operation panel 11 ', for example, if the winding start button in which 500 g is input is pressed, the winding control device 13' is released as follows. Control 16.

10 is a graph showing the reference weight change amount stored in the ROM 13b. In this graph, the amount of change in the weight of the winder spool 1 'from time 0 (winding start) to time T1 increases linearly to the value G1 at a constant rate, and the time interval from time T1 to time T2 remains the value G1. The interval between the time T2 and the time T3 (winding end) is constant, and has a characteristic of decreasing at a constant rate from the value G1.

The winding control apparatus 13 'samples the weight of the winder spool 1' input from the weighing machine 40 at predetermined time intervals from the start of winding, and stores it in RAM 13c sequentially. Therefore, the weight change amount is calculated at time tn by subtracting the weight value of the previous time (time tn-1) from the weight value sampled at a certain time tn (n = integer). The winding speeds of the unwinding motor 3 and the spindle motor 7 are controlled so that this weight change amount is equal to the reference weight change amount corresponding to the time tn. At this time, the winding control device 13 'controls the unwinding speed of the unwinding motor 3 in accordance with the unwinding speed of the spindle motor 7.

That is, the winding control device 13 'controls the unwinding motor 3 and the spindle motor 7 so as to linearly increase the weight change amount at each sampling time from the start of winding to the time T1 as shown in the characteristic value line L1. . As a result, the conveying speed of the real winder 2 gradually increases, and 100 g is wound around the bobbin 6 in this period.

Further, the winding control device 13 'controls the unwinding motor 3 and the spindle motor 7 so that the weight change amount at each sampling time becomes a constant value G1 as shown by the characteristic value line L2 in the period from the time T1 to the time T2. As a result, the real winder 2 is wound up at a constant feed rate, and 300 g is wound up in this period.

Further, in the period from the time T2 to the time T3 (winding end), the winding control device 13 'loosens the motor so that the amount of change in weight at each sampling time is linearly zero from the constant value G1 as indicated by the characteristic value line L3. And spindle motor 7. As a result, the real winder 2 is wound up at a constant feed speed, and 100 g is wound up in this period.

In this way, from the time 0 to the time T3 by controlling the unwinding motor 3 and the spindle motor 7 so that the weight change amount of the winder spool 1 'coincides with the reference weight change amount at each time from the start of the winding to the end of the winding. 500 g of thread winder 2 is wound around bobbin 6. Further, during this winding period, the winding nozzle 5 reciprocates in the directions of arrows X1 and X2 to sequentially move the winding position of the thread winder 2 on the bobbin 6 so that the thread winder 2 is moved to the bobbin 6 at a uniform winding thickness. It works to roll up.

During this winding period, the winding tension of the seal winder 2 is detected by the torque detection unit 4b as the tension Ta of the seal winder 2 wound around the rod 4a in the Z phase, that is, the torque of the torque motor 4. Therefore, this torque detection value is sent to the winding control apparatus 13 'through the tension control apparatus 16. FIG.

When it is judged that the said torque detection value becomes larger than a predetermined value, the winding control apparatus 13 'controls so that the rotational speed of the unwinding motor 3 may raise with respect to the rotational speed of the spindle motor 7, and will reduce a winding tension and return to a predetermined value. On the other hand, when it is determined that the torque detection value is smaller than the predetermined value, the winding control device 13 'controls the rotational speed of the unwinding motor 3 to be lowered relative to the rotational speed of the spindle motor 7, and raises the winding tension to return to the predetermined value. .

Thus, by detecting the tension Ta of the thread winder 2 by the rod 4a provided in the torque motor 4, the winding tension of the said thread winder 2 is controlled uniformly. In particular, it is possible to prevent the delay or breaking of the seal winder due to the change in the winding tension at the start and end of the winding.

In this embodiment, although the structure which installs the torque motor 4 in front of the winding nozzle 5 is employ | adopted, by setting it as the structure provided with the torque motor 4 between the winding nozzle 5 and the bobbin 6, winding tension can be detected and controlled more correctly. It is possible. In this case, instead of the torque motor 4, various sub-motors capable of high-precision positioning may be used. Further, a means for detecting the tension of the seal winder can be considered using a configuration that detects the displacement of the movable member pressed against the seal winder 2 (which varies with the tension of the seal winder) by an operating transformer or the like. . In this case, it is not necessary to wind the thread winder 2 in the Z phase as in the rod 4a, and it is possible to suppress the increase in the transient tension due to the start of winding.

Moreover, although this embodiment demonstrated the case where this invention is applied to the winding apparatus of a real winder, this invention is not limited to this, It is applied also to the winding of glass fibers etc. which are sold by weight similarly to the real winder 2. It is possible to do
