Problems solved by technology

In the high-speed spinning winding device, the stability of the line speed is usually required to be less than ±0.1%, and it is very difficult to adjust the PID gain with the usual PID control
For example, when increasing the setting PID gain in order to improve the responsiveness, the PID calculation result will change greatly, and the line speed tends to fluctuate; When the load state changes or the line speed detection value changes due to noise, etc., the time to return to a stable state is very slow

Embodiment Construction

[0018] Hereinafter, preferred embodiments of a speed control method and a speed control device for a coiler for implementing the present invention will be described with reference to the accompanying drawings.

[0019] figure 2 It is an overall configuration diagram of a high-speed winding device (hereinafter, simply referred to as "coiling device") showing an embodiment of the present invention.

[0020] figure 2 The winding device 1 of the present embodiment shown is for high-speed winding of the source yarn ( In the devices of "sliver (sliver)") S1 to Sn, the cylindrical winding bobbin 2 is arranged at a predetermined position (winding position). The winding bobbins 2 simultaneously wind the slivers S1 to S5 from the respective cylindrical bobbins B1 to B5.

[0021] A guide bobbin 3 is supported on the take-up bobbin 2 in a detachable manner. The guide bobbin 3 abuts against the winding bobbin 2 with a predetermined contact pressure and guides the slivers S1 to S5 whi...

Abstract

The speed controller for the coiling apparatus possesses one PID calculation device for the PID calculation for the essentially identical frequency detecting value corresponding to the detected linear speed value of the speed sensor and the frequency command value corresponding to the given linear speed command value; and one PID calculating result correcting device to correct the PID calculating result and comprising a last frequency input unit, a subtraction calculation unit, a frequency dependence calculating unit, a limit unit and an addition calculation unit. The lower the motor rotation speed, the less the dependence of the PID calculating result on the output frequency. The corrected PID calculating result is used as the output frequency to the motor.

Description

technical field [0001] The present invention relates to a speed control method and a speed control device of a winding device such as a high-speed spinning winding device, and particularly relates to a power supply device using a frequency converter as a motor for driving a winding bobbin, and the output frequency of the frequency converter can be used to change the rotation of the motor. Speed, the stable linear speed control method of the coiling device that performs fixed control of the linear speed of the coiling device. Background technique [0002] As a conventional control method for constant linear speed control of high-speed spinning winding devices, etc., it is well known that a general PID (proportional calculus) control is performed using an inverter as a motor power supply device, so that the feedback linear speed follows the given linear speed. speed command. [0003] figure 1 It is the main structure of the inverter (INV) speed control unit used in the conve...
