Abstract
Description
- The present invention relates to a device and method for winding wire on a bobbin.
- The manufacture of high quality coils entails the necessity of the winding device winding wire onto a bobbin while maintaining a constant tension on the wire. In order to maintain a constant tension, the speed at which the bobbin winds the wire must be equal to the speed at which the wire source feeds the wire.
- When wire is wound onto the bobbin, the radius of the bobbin increases. On the other hand, the radius of the drum, onto which wire is pre-wound and which acts as a wire source, decreases. In addition, the cross sectional shape of the bobbin may not only be round. For example, when the bobbin is square, its radius varies as a result of the rotational angle of the bobbin. As a result, in order for the winding speed and the feeding speed to be equal, it is necessary to appropriately control the rotational speed of the drum depending on the variation in the radius of the drum and the bobbin.
- In this regard, Tokkai Hei 3-159541 published by the Japanese Patent Office in 1991 discloses a technique of calculating the increase in the radius of the bobbin from the contour data of the bobbin and the wire and the length of wire which has been wound. The radius of the drum which acts as the wire source is detected using a sensor and the rotational speed of the drum is controlled so that the winding speed and the feeding speed are equal.
- However in the conventional technique, since it is necessary for the contour data of the bobbin and the wire to be pre-input into the control device, the data must be repeatedly input each time the bobbin or the wire is changed. Furthermore, when the cross section of the bobbin is not round, the complexity of the calculation of the radius of the bobbin increases significantly.
- It is therefore an object of this invention to provide a winding device and method of winding which can maintain a constant tension on a wire with a simple structure and control means.
- In order to achieve the above object, this invention provides a winding device comprising a wire source feeding wire, a spindle which supports a bobbin which winds the wire and a drive mechanism which rotates the spindle. The winding device further comprises a winding speed sensor which is provided on the upstream of the bobbin and detects a winding speed of the wire which is wound onto the bobbin and a controller which controls a feeding speed of the wire fed from the wire source depending on the winding speed.
- According to an aspect of this invention, the winding speed sensor is an encoder. A pulley is fixed on a rotational axis of the encoder and the wire is lead to the bobbin via the pulley.
- According to another aspect of this invention, the wire source is a spool on to which the wire is wound. The device further comprises a feeding motor which rotates the spool and the controller controls a rotational speed of the feeding motor.
- According to yet another aspect of this invention, the winding device further comprises a feed relay mechanism which relays the wire from the wire source and feeds the wire. The controller controls a speed at which the feed relay mechanism feeds the wire.
- According to yet another aspect of this invention, the winding device further comprises a tension exerting mechanism which exerts a predetermined tension on the wire. The tension exerting mechanism is provided between the wire source and the winding speed sensor.
- According to yet another aspect of this invention, the winding device further comprises a tension sensor which detects a tension which is exerted on the wire by the tension exerting mechanism. The controller corrects the feeding speed of the wire based on the tension.
- According to yet another aspect of this invention, the tension exerting mechanism comprises a rigid tension arm rotatable about a base, a guide which is provided on a tip of the tension arm and guides a wire between the wire source and the winding speed sensor, and an elastic member provided to the tension arm. The tension sensor detects a tension exerted on the wire based on a rotational angle of the tension arm.
- According to yet another aspect of this invention, the tension arm becomes thick towards the base and becomes thin towards the tip.
- In order to achieve the above object, this invention also provides a winding method of wire which is fed from a wire source onto a bobbin which is supported by a spindle. The method comprises detecting a winding speed of the wire wound onto the bobbin and controlling a feeding speed of the wire from the wire source depending on the winding speed.
- According to an aspect of this invention, the winding method further comprises detecting a tension exerted on the wire and correcting the feeding speed based on the tension.
- The details as well as other features and advantages of this invention are set forth in the remainder of the specification and are shown in the accompanying drawings.
- Fig. 1 is a perspective view showing a winding device according to the present invention.
- Fig. 2 is a block diagram of the control system of the winding device.
- Fig. 3 is similar to Fig. 1, but shows a second embodiment of the present invention.
- Referring to Fig. 1 of the drawings, the winding device comprises a spool 1 on which
wire 2 is pre-wound and which acts as a wire source. The spool 1 is connected to afeeding motor 3 and thefeeding motor 3 rotates the spool 1 to feed thewire 2. - The
wire 2 passes through afeed mechanism 4 and is lead onto abobbin 7 which is provided on the tip of a spindle 6. The spindle 6 is rotated by adrive mechanism 16. When thebobbin 7 rotates, thewire 2 is wound onto thebobbin 7. - The
feed mechanism 4 is provided with atension arm 10 on the downstream of thefelt pulley 8 used to dust thewire 2. Abase 10A of thetension arm 10 is supported in free rotation by aplate 9 and can rotate along theplate 9. The rotational angle of thetension arm 10 is detected by apotentiometer 11 provided on thebase 10A. - A
pulley 12 is provided on the tip of thetension arm 10 which guides thewire 2. Thewire 2 which is lead from the spool 1 to thefelt pulley 8 passes through thepulley 12 and apulley 13 which is nearer to thebobbin 7 than thepulley 12 and is lead to thebobbin 7. Instead of thepulley 12 on the tip of thetension arm 10, a ring shaped member which leads thewire 2 may be provided. - The
pulley 13 is fixed onto the rotational axis of anencoder 14 provided on theplate 9. The speed of thewire 2 which is lead to thebobbin 7 via thepulley 13 is detected by theencoder 14. - A
spring 15 is provided between thetension arm 10 and aboss 8A provided on theplate 9. Thespring 15 effects a force in a clockwise direction on thetension arm 10 and thus a tension corresponding to the elastic force of thespring 15 is exerted on thewire 2. When there is an increase in the tension on thewire 2, since the spring extends and thetension arm 10 rotates in a counter clockwise direction, it is possible to calculate the variation in the tension on thewire 2 from the variation of the rotational angle of thetension arm 10. - The
tension arm 10 is constructed from a sufficiently rigid material which is hard to bend so that the variation in tension is accurately reflected in the rotational angle of thetension arm 10. In addition, a light material is used so that the responsiveness to the variation in tension is high. In order to achieve high rigidity and responsiveness, the tension arm becomes thick towards thebase 10A and becomes thin towards the tip. - A
controller 17 rotates the spindle 6 at a predetermined rotational speed. Furthermore thecontroller 17 controls the feeding speed of thewire 2, that is to say, the rotational speed of thefeeding motor 3 based on the winding speed of thewire 2 on thebobbin 7 detected by theencoder 14, the tension detected by thepotentiometer 11 and the radius of the pulley 1 which is obtained by calculation or by a sensor. - Fig. 2 is a block diagram which shows the control system of the winding device.
- The
controller 17 comprises a D/A converter 21, a CPU (Central Processing Unit) 22,amplifiers operational amplifier 24, aresistor 25 and avolume 27. - Pulses output from the
encoder 14 are input into theCPU 22 after being converted into analogue signals by the D/A converter 21. - The
potentiometer 11 is a variable resistor which varies the resistance value depending on the rotational angle of thetension arm 10 and which forms a non-inverse amplification circuit together with theoperational amplifier 24 and theresistor 25. The output of the non-inverse amplification circuit varies depending on the value of the resistance of thepotentiometer 11, is amplified by theamplifier 26 and output to theCPU 22. - The
CPU 22 corrects the signal from theencoder 14 based on the variation in tension and the radius of the pulley 1 and outputs the modified signal to theamplifier 23. - When there is no variation in the tension of the
wire 2, no correction of the signal is made and the rotational speed of the feedingmotor 3 is controlled so that thewire 2 is fed at the same speed as the winding speed of thewire 2 onto thebobbin 7 as detected by theencoder 14. In contrast, when there is variation in the tension on thewire 2 and thepotentiometer 11 moves from its zero point, the variation in tension is fed back to theamplifier 23 and regulates the rotational speed of the feedingmotor 3. - The
volume 27 is a variable resistor which regulates the output voltage of the non-inverse amplification circuit. When thepotentiometer 11 is at zero point, in other words, when the rotational angle of thetension arm 10 takes an angle which exerts a predetermined tension on thewire 2, the output of the non-inverse amplification circuit is regulated to take a value of zero. - The arrangement of the control system is not limited to the circuit shown in Fig. 2. For example, the variation in tension or the winding speed of the
wire 2 could be detected using a device other than theencoder 14 or thepotentiometer 11. It is possible to use an AC motor, a DC motor, a step motor or the like as the feedingmotor 3. The detected signal from theencoder 14 need not be converted into an analogue signal by the D/A converter 21 but may be directly processed digitally and the feed back control can be performed by hardware or software. - The winding device of the present invention performs winding as set out below.
- The
wire 2 fed from the spool 1 is lead to thebobbin 7 through thefeed mechanism 4 and is wound onto thebobbin 7 which rotates at a predetermined rotational speed. - The feeding
motor 3 feeds a necessary length ofwire 2 by rotating the spool 1. The rotational speed of the feedingmotor 3 is controlled based on the wire winding speed of thebobbin 7 detected by theencoder 14 and the radius of the spool 1 obtained by a sensor or by calculation. - As a result, it is possible to make the feeding speed of the
wire 2 from the spool 1 agree with the winding speed of thebobbin 7 and stabilize the tension of thewire 2. Hence, it is not necessary to calculate the increase in the radius of thebobbin 7 due to thewound wire 2. - When the cross sectional shape of the
bobbin 7 is not round, as shown in Fig. 1, the radius of thebobbin 7 varies according to the rotational angle. However as opposed to the conventional technique, it is not necessary to calculate the variation in the radius according to contour data of thebobbin 7, etc. - Furthermore when the
wire 2 is slack and theencoder 14 rotates in the inverse direction, thecontroller 17, which receives the detection signal from theencoder 14, rotates the feedingmotor 3 in the inverse direction and returns thewire 2 in the direction of the spool 1. - The rotational displacement of the
tension arm 10 due to the variation in the tension is fed back to the feedingmotor 3 and the rotational speed of the feedingmotor 3 is regulated. In this way, momentary minute variations in the tension of thewire 2 can be automatically absorbed. Since thetension arm 10 is controlled to maintain a constant angle, normally a constant tension is exerted on thewire 2. - When a tension variation on the
wire 2 is generated by a disturbance or the like, the displacement of thetension arm 10 is detected by thepotentiometer 11 and fed back to the feedingmotor 3 which automatically regulates the rotational speed of the feedingmotor 3. - Fig. 3 shows another embodiment of the present invention.
- This embodiment differs from the previous embodiment in that a
feed relay mechanism 43 comprising apulley 41 and a feedingmotor 42 is provided on the downstream of aspool 40 which acts as the wire source. - The provision of the
feed relay mechanism 43 allows thewire 2 which is wound beforehand on thespool 40 to be provided to thetension arm 10 after being temporarily wound on thepulley 41 which is driven rotationally by the feedingmotor 42. - In this case, since the amount of
wire 2 wound on thepulley 41 is constant and the radius of thepulley 41 does not vary, the length ofwire 2 fed from thepulley 41 is determined depending on the number of rotations of thepulley 41. - Hence according to this embodiment, the feeding speed of the
wire 2 is decided only by the rotational speed of the feedingmotor 42. Thus, it is not necessary to correct the rotational speed of the feedingmotor 42 depending on the radius of the spool 1 as in the previous embodiment. - The embodiments of this invention in which an exclusive property or privilege is claimed are defined as follows:
