Automatic control device for doffer

Abstract

The invention discloses an automatic control device for a doffer. A W-axis servo motor is used for the forward movement of the automatic doffer, and an X-axis servo motor, a Y-axis servo motor, and a Z-axis servo motor are used for the three-dimensional motion of a tube-pulling mechanism relative to the doffer; when a motion controller receives a synchronous signal sent by a tube-pulling detection laser sensor, the tube-pulling mechanism is controlled via the Y-axis servo motor to move relative to the travelling direction of the automatic doffer to a position facing a yarn tube with full yarns, and to keep relatively static, and then the yarn tube with the full yarns is pulled out and placed in a yarn-receiving basket of the automatic doffer by controlling the X-axis servo motor, the Z-axis servo motor and the tube-pulling mechanism; and when an empty spindle positioning signal sent by a tube-inserting detection laser sensor is received, a tube-inserting mechanism is communicated and controlled to insert an empty yarn tube on a corresponding empty spindle, so as to realize automatic tube-pulling and tube-inserting control on the doffer, thus improving the automation level and the production efficiency of the doffer.

Description

technical field [0001] The invention relates to the technical field of automatic control in the textile industry, in particular to an automatic control device for a doffing machine. Background technique [0002] With the price increase of textile raw materials and energy shortage, the labor cost has increased relatively, and the automatic doffing machine can reduce labor and improve labor efficiency, which will definitely become the development trend in the next few years. [0003] At present, although there are some spinning and doffing integrated machines, the cost of replacing equipment in old factories is relatively high, so most spinning mills still use manual doffing, that is, unplug the full bobbins from the spindles of the spinning frame and replace them with empty yarns tube; the labor intensity of the doffing workers is high and the efficiency is low, and the number of spindles in general spinning mills is large, and a shutdown requires multiple doffing workers to ...

[0003] At present, although there are some spinning and doffing integrated machines, the cost of replacing equipment in old factories is relatively high, so most spinning mills still use manual doffing, that is, unplug the full bobbins from the spindles of the spinning frame and replace them with empty yarns tube; the labor intensity of the doffing workers is high and the efficiency is low, and the number of spindles in general spinning mills is large, and a shutdown requires multiple doffing workers to operate at the same time to complete the doffing work, wasting too much manpower; Working in high-intensity labor is easy to cause damage to the body. Therefore, the development of automatic doffing machines is of great significance to the equipment transformation of textile mills, to improve production efficiency, reduce labor intensity of workers, and improve automation and continuous production.
