Automatic cop drawing device and method of ring spinning frame

Abstract

The invention discloses an automatic cop drawing device and method of a ring spinning frame, relates to an automatic doffing cop drawing device of a ring spinning frame, in particular to an automatic cop drawing device and method of a ring spinning frame for separating and collecting the cop and a spindle. The automatic cop drawing device comprises a pneumatic manipulator (7), a horizontal moving assembly (1), a lifting assembly (5), a yarn cutting part (9) and a bobbin collecting device; up-down one dimension motion of a lifting cylinder and the clamping and releasing of the pneumatic manipulator are realized by the steps of initializing, horizontal moving to a rear position, vertically moving to a lower position, cop clamping, drawing the bobbin to an upper position, overturning, yarn cutting, bobbin collecting and the like, so the cop is drawn and descended, harm to the yarns in the bobbin drawing process is avoided, no radial force is generated to an ingot, and the automatic cop drawing device has the beneficial effects of reducing labor intensity of a worker and worker number and improving operation efficiency and doffing quality.

Description

technical field [0001] The invention relates to an automatic doffing bobbin pulling device for a ring spinning frame, in particular to an automatic bobbin pulling device and method for separating and collecting bobbins from spindles. Background technique [0002] my country is a big textile country, and the textile industry occupies a large proportion in the national economy and foreign exchange earned through export. With the continuous development of the textile industry, the degree of automation of textile equipment is getting higher and higher. However, the traditional manual doffing method is mostly used in the spinning frame doffing process. Due to the high labor intensity and large number of workers, manual doffing has become The bottleneck that restricts the production and development of spinning mills. Therefore, using automatic doffing to improve the equipment level and automation of the textile industry is in line with the national industrial policy, and it is also...

Problems solved by technology

[0004] In order to solve the problem of high labor intensity and large number of workers for manual doffing, people are constantly researching automatic doffing mechanism

The disadvantage of the early double-disc mechanical doffing trolley is that it produces a large radial force on the spindle and also causes damage to the yarn

In recent years, the intelligent doffing machines developed by some enterprises mostly draw on the collective doffing scheme of the long car for the pipe pulling mechanism. The airbag robot is used to pull the bobbin from the top of the bobbin. The movement control of the robot adopts the AC servo system to Three-dimensional space movement is realized, and some enterprises use pneumatic components to realize two-dimensional movement. The number of movement axes is large, which will inevitably lead to complex mechanism, high cost and high failure rate
