Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects the tension of yarn fed at a constant speed,
A turret-type spindle drive type winder that winds the yarn while controlling spindle rotation using the tension signal, and switches the spindle every time the winding amount reaches a predetermined amount, and a power supply unit for driving the winder. The present invention relates to a yarn winding device comprising:

Conventional turret-type spindle drive type winding machines wind yarn with one spindle, and when the winding amount approaches a predetermined amount, the motor for driving the other standby spindle is started, and the standby spindle is activated. Since it was necessary to maintain the rotation at a predetermined level in preparation for the yarn switching operation, two sets of power supplies were required for one winding machine.

For this reason, a yarn winding device equipped with a secondary turret type spindle drive type winder is more expensive than a yarn winding device equipped with a conventional turret type Surf Ace drive type winder. However, the problem is that the installation area of the power supply device becomes large. An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art, and to provide a yarn winding device that is free from restrictions on yarn switching operations and has a smaller power supply device for the winder. .

In order to achieve this object, the present invention has a configuration including a plurality of winding machines that alternately switch two spindles each equipped with a motor and a rotation detector to wind the yarn, and a winder for each winder of the plurality of winders. Selectively switch between a plurality of tension detectors for detecting the tension of the yarn wound on the machine, and a motor and rotation detector provided on one of the two sets of spindles of each winding machine. and a plurality of individual power supply devices for supplying electric power corresponding to the output signal of the rotation detector or the tension detector selected by the switching device to the motor selected by the switching device. , a selection device for selecting and switching the motor and rotation detector of one winding machine from among the motor and rotation detector of each winding machine not selected by the switching device; A common power supply device for supplying power corresponding to the output signal of the rotation detector selected by the selection device to the motor is installed, and when threading for the first time or threading when the thread breaks midway, The yarn winding device is characterized in that an individual power supply unit starts the motor, and when switching yarns, a common power supply unit starts the motor on the side that is not winding. Embodiments of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a turret-type spindle drive type winding machine, which includes a traverse device 11 that traverses a yarn 8 supplied from a godet roller 7 that rotates at a constant speed, and a spindle that winds the traverse yarn 8. 12, 13, and a motor 14 for driving the spindles 12, 13, respectively.
15, rotation detectors 16 and 17 for detecting the rotation speeds of the spindles 12 and 13, respectively, and a dial plate 18 for alternately switching the spindles 12 and 13 when switching threads, and 2 is a switching device. , changeover switches 21 and 22 for selecting either the motor 14 and rotation detector 16 which are coupled to the spindle 12, or the motor 5 and rotation speed machine 17 which are coupled to the spindle 13; This is a tension detector that detects tension.

4 is an individual power supply device, which includes an initial speed setting controller 42 that maintains the spindle rotation at a predetermined speed while receiving the output signal of the rotation detector selected by the changeover switch 21; a tension setting detector 41 that controls the rotation of the yarn 8 to maintain the winding tension of the yarn 8 at a predetermined value; and a variable frequency device 43 for supplying the corresponding electric power to the motor. 5 is a selection device 5 that selects any one of the motors and rotation detectors of each winding machine not selected by the switching device 2. It consists of changeover switches 51 and 52 for selecting the motor and rotation detector provided in the winding machine, and 6 is a common power supply unit provided for a plurality of winding machines, which is selected by the changeover switch 51. An initial speed setting controller 61 receives a signal from a rotation detector and maintains the rotation of a spindle connected to the rotation detector at a predetermined speed. It consists of a variable frequency power supply device for supplying power to the motor.

In addition, the spindle 12 is changed by switching the changeover switches 21, 22, 44, 51, and 52 and rotating the turret board 18.
and 13 can be switched as appropriate by a signal from a controller (not shown) that is activated when threading or switching threads. Note that the power supply device 46 is
Although the controller and the variable frequency power supply device have been described as a combined device, the controller and the variable frequency power supply device may be independent devices, and the switching device 4 and the selection device 5 may be independent devices. Although described as a device, it may be configured as a combined device.
Division and integration of devices within the scope of not changing the gist of the present invention shall be included in the present invention. Next, the operation will be explained.

For the first threading, first set the speed of the initial speed setting controller 42 so that the outer peripheral speed of the bobbin attached to the spindle 12 is slightly faster than the yarn feeding speed of the yarn 8, and then 44 as shown in the figure, and turn on the start switch (not shown) of the variable frequency power supply device 43.

Then, the circumferential speed of the bobbin attached to the spindle 12 is maintained at a speed slightly faster than the yarn feeding speed of the yarn 8, so the yarn 8 is taken up by a thread crane device (such as an aspirator) and transferred to the spindle 1.
Thread the thread onto bobbin 2. At the same time as threading is completed, the changeover switch 44 is switched to change the supply signal to the variable frequency power supply device from the output signal of the initial speed setting controller 42 to the tension setting detector 4.
Switch to output signal 1. By this switching, the tension of the yarn 8 is controlled to a predetermined value, and winding of the yarn 8 is started. As described above, threading is performed on all winding machines. In addition,
If the yarn 8 breaks during winding, replace the thread change bobbin on the spindle 12 with an empty bobbin and repeat the above threading process, or rotate the spindles 12 and 13 by rotating the winding wheel 18. At the same time, the changeover switches 21 and 22 are switched to repeat the above-mentioned thread threading. That is, when threading is to be carried out, the motor is started by an individual power supply device provided for each winding machine and the thread is threaded. As the winding of the yarn 8 progresses and the yarn becomes full, the spindle 12 on the winding side and the spindle 13 on the standby side are switched and the yarn is switched. , is selected by the selector switches 51 and 52 of the selection device 5, and is started by turning on the start switch (not shown) of the variable frequency power supply device 62.

Then, the circumferential speed of the bobbin attached to the spindle 13 is maintained at a speed slightly faster than the feeding speed of the yarn 8, so the turret plate 18 is rotated to exchange the spindles 12 and 13, and the winding is performed on the spindle 12. The taken thread 8 is switched to the spindle 13 by a thread switching device (not shown).
At the same time as this switching is completed, the start switch (not shown) of the variable frequency power supply device 62 is turned off, and the changeover switches 51 and 52 of the selection device 5 are switched to the waiting spindle of the adjacent winding machine. At the same time as this switching is completed, the changeover switches 21 and 22 of the multifunction device 2 are switched from the spindle 12 side to the spindle 13 side. When the series of switching is completed, the thread 8 is wound again with a predetermined tension, and the thread switching for one winding machine is completed. Next, the motor of the adjacent winding machine selected by the selection device 5 is started, and as described above, as the thread is changed by replacing the spindle and switching the switch, multiple winding machines are selected in one cycle of the selection device 5. The entire winding machine can change the yarn. That is,
When switching yarns, one common power supply unit can be used to sequentially start each motor for a plurality of winding machines. (It is also possible to increase the capacity of the common power supply unit so that two or more winding machines can switch the yarn at the same time,
If this is done, it is not possible to compensate for the difference in slip between each motor, so the rotation accuracy of the spindle will deteriorate, which is undesirable as there is a risk that the success rate of thread switching will decrease.)
As detailed above, according to the present invention, in a yarn winding device equipped with a turret type spindle drive type winding machine, an individual power supply device for each winding machine and one winding machine from each winding machine are provided. The yarn winding device is equipped with a selection device for selection and one common power supply unit common to each winder, and when threading the yarn for the first time or threading when the yarn breaks midway, the winding is performed using an individual power supply device. The yarn winding device starts the motor on the take-up side or the standby side, and when switching yarns, the motors on the standby side can be started sequentially using a common power supply. Previously, the same number of power supplies were required for both the side and standby sides, but now there is only one common power supply for the standby side, which significantly reduces the cost of the yarn winding device and also reduces the installation area of the power supply. This has the excellent effect of reducing building construction costs.
