Abstract

PURPOSE:To certainly prevent the wire cut and winding deflection of an extremely thin wire by feedback-operating the tension of the extremely thin wire on a tension transmitting lever which is electrically measured by a tension detector into a tension generator. CONSTITUTION:An extremely thin wire 1 supplied from a driving-out spool 6 is applied with a tension through an tension transmission spool 5 and a tension applying pulley 2 by a tension generator 10, and taken up onto a taking-up spool 15 through a processing device 20. The processing speed is control led by a driver 15 and a motor 16, with a deviation between the output of a taking up speed setting device 19 and the output of a taking-up tachogenerator 17. Further, the driving-out speed of the extremely thin wire 1 is control led similarly by a driver 9, and corrected by the output of a tension applying pulley position detector 3. The tension is detected as the strain of the tension transmitting lever 5 by a tension detector 13, and compared with the output of a tension setting device 11 through a conversion amplifier 14 by a driver 12, and control led by the tension generator 10. Thus, the wire cut and winding deflection can be certainly prevented.

報参照）が提案された。[Prior art and problems to be solved by the invention] A conventional ultra-fine wire winding device, as shown in FIG. , one end pivotally supports the pulley °-2, and the other end is directly connected to the input shaft of a tension applying pulley position detector 3 such as a rotary encoder, differential transformer, potentiometer, etc., and is tensioned by a tension applying spring 4. The rotational speed of the feeding motor 7 is detected by the tension transmission lever 5 biased in the application direction and the signal from the feeding tacho generator 8 which is directly connected to the feeding motor 7 that drives the feeding spool 6. It was equipped with a tension applying device consisting of a feed-out motor driver 9 that adjusts the rotational speed of the feed-out motor 7 according to the output of the feed-out motor. However, since this tension applying device is designed to keep the applied tension constant and cannot change the tension, the radial component of the tension increases as the take-up diameter increases on the take-up spool (not shown). This causes the upper layer of the ultra-fine wire to bite into the lower layer, and when unwinding it, an excessive force is applied while the ultra-fine wire is caught, causing the problem that the ultra-fine wire is likely to break. Furthermore, since the tension generating means is a spring, vibrations that are likely to occur in the spring cause vibrations (resonance) in the feeding speed control loop (consisting of the feeding motor 7 and the feeding tacho generator 8) for tension control. There was a problem that the ultra-thin wire would break or become uncoiled. Therefore, as shown in FIG. 6, for example, a tension generator 10 such as a small permanent magnet motor or other electromagnetic force generator is used as the tension generator. The other end of the tension transmission lever 5 is directly connected to the output shaft of the tension generator 10 without using a spring or the like, and a tension generator driver 12 controlled by the tension setting device 11 generates a set tension in the tension generator 10. This tension applying device attempts to change the set tension linearly in inverse proportion to the winding diameter of the take-up Lisbourg, that is, in proportion to the winding diameter of the delivery spool 6, by changing the output of the tension setting device 11. (Refer to Japanese Patent Laid-Open No. 61-226466) was proposed.

細線の断線や巻ずれを防止することができなかった。However, this tension applying device also had the following problems. That is, there is a relationship τ = KI between the torque (tension) τ generated by a small permanent magnet motor or force generator used as the tension generator 10 and the armature current (tension setting device m) I. However, when the value of the current I is near zero, a dead zone occurs as shown in Fig. 7 due to frictional resistance between the rotating shaft and the bearing or the current supply brush, and the tension in the ultra-thin wire 1 and the tension generation occur. Since the torque generated by the device 10 is balanced, even if the current (2) is changed to change the tension, a dead zone is generated due to the frictional resistance as shown in FIG. 8, and this appears as hysteresis. It was not possible to linearly change the set tension, and it was not possible to prevent wire breakage or winding misalignment of the ultra-fine wire.

In an ultrafine winding device equipped with a tension applying device consisting of a tension transmitting lever directly connected to the tension transmitting lever, a tension setting device for generating a set tension in the tension generator, and a driver for the tension generator, the tension transmitting lever is directly connected to the tension transmitting lever. By providing a tension detector that electrically measures the tension applied to the ultra-fine wire and feeding back the detection output of the tension detector to the tension generator driver, the setting current of the tension generator and the tension application can be adjusted. The tension set on the ultra-fine wire by the pulley can be varied linearly to improve instability caused by vibration and to compensate for nonlinearity caused by friction and hysteresis.
