Automatic control system of two-for-one twister

Abstract

The invention discloses an automatic control system of a two-for-one twister. The system comprises a programmable process controller for controlling the whole machine, a twisting frequency converter for controlling a spindle motor of the whole machine, a winding frequency converter for controlling a winding motor, a transverse movement server for controlling a transverse servo motor, a first rotating speed sensor and a second rotating speed sensor, wherein the firs rotating speed sensor and the second rotating speed sensor are installed on a spindle shaft and a winding shaft respectively. The system is characterized in that the programmable process controller is in data connection with the twisting frequency converter, the winding frequency converter and the transverse movement server and controls the twisting frequency converter, the winding frequency converter and the transverse movement server through fed frequency, and the programmable process controller adjusts power of the fed twisting frequency converter and power of the winding frequency converter in real time according to actual spindle shaft and winding shaft rotating speed signals fed back by the two rotating speed sensors in data connection with the programmable process controller. The control system has the advantages that due to the fact that the automatic equipment is assembled to replace an existing gear case transmission device on the two-for-one twister, the structure is simplified, and the operating state of the machine can be changed more flexibly through a human-computer interface.

Description

[0001] technical field [0002] The invention belongs to the field of textile machinery, in particular to an automatic control system for a two-for-one twister. Background technique [0003] Two-for-one twister is a kind of spinning equipment that twists two or more strands of yarn into one yarn after high-efficiency twisting, and then automatically controls equipment such as: programmable process controller, frequency converter, servo controller , the popularity of sensors, etc., and the manufacturing cost and use cost of these devices are getting lower and lower. A large number of textile machinery manufacturers have adopted automation equipment with a high degree of automation, easy operation and low procurement costs. At present, most two-for-one twisters are driven by a single motor, and then the power is distributed to each rotating area through mechanical components such as gear boxes and transmission belts to drive the two-for-one twister to run. Although this mode h...

Problems solved by technology

At present, most two-for-one twisters are driven by a single motor, and then the power is distributed to each rotating area through mechanical components such as gear boxes and transmission belts to drive the two-for-one twister to run. Although this mode has stable performance, it lacks the power of two-for-one twisters. Diversity and flexibility of requirements in the production process, and the structure of the two-for-one twister with a gearbox is relatively bloated and maintenance is complicated
