Intermittent automatic tube drawing device

Abstract

The invention relates to an intermittent automatic tube drawing device which comprises a doffing trolley. The doffing trolley is arranged on a guide rail assembly and can travel, and the traveling route of the doffing trolley is parallel to the central line of a spindle of a spinning frame. The intermittent automatic tube drawing device is characterized in that the doffing trolley is provided with a traveling driving mechanism, a tube drawing mechanical arm and a control system, wherein the traveling driving mechanism is used for driving the doffing trolley to travel intermittently, the tube drawing mechanical arm is used for drawing yarn-loaded tubes on the spinning frame and collecting the yarn-loaded tubes, the control system is used for controlling the traveling driving mechanism and the tube drawing mechanical arm to act crossly, the tube drawing mechanical arm stops drawing tubes when the traveling driving mechanism drives the doffing trolley to travel, and the tube drawing mechanical arm starts to draw tubes when the traveling driving mechanism drives the doffing trolley to stop. The intermittent automatic tube drawing device has a smart structure and high automation degree, can realize automatic doffing so as to reduce labor intensity of workers, save the labor time, and improve the doffing efficiency, yarn collecting efficiency and empty tube changing efficiency, and has high action accuracy, lower production cost and low fault rate.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and equipment, and relates to an automatic doffing device, in particular to an intermittent automatic tube-extracting device applied to a spinning frame in which a spindle and a bobbin are friction-driven. Background technique [0002] With the continuous development of the textile industry, the degree of automation of textile production is also getting higher and higher. The improvement of automation level can effectively reduce production costs and improve enterprise efficiency, which is the only way for my country to move from a large textile country to a textile power. [0003] Doffing workers are one of the main workers in the traditional spinning frame workshop, so doffing automation is one of the important contents of spinning workshop automation, and solving the problem of extubation and intubation is the core problem of realizing doffing automation. At present, the doffing oper...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: (1) Since the bobbin rotates with the spindle at high speed, there will be a large adhesive force between the full bobbin and the spindle, and manual doffing requires a lot of labor intensity, and the workload of the doffer is heavy. , the task is heavy, monotonous and repetitive, and the production efficiency is low. The spinning frame generally has a large number of spindles and requires a large number of workers, resulting in high labor costs.

(2) The hands of the doffing worker sweat a lot, and they are easy to get dirty when cleaning. In case it is not clean, all the bobbins on a car have to pass through the hands of the doffer, and it is inevitable that they will be wiped on the bobbins. affect product quality

(3) It is necessary to force the hand upwards when pulling the yarn, especially on the slope of the bobbin, it is easy to slide the yarn upwards, causing the groove to fall off the ring; The problem that the spindle belt falls off, causing the oil pollution from the spindle belt

These complex mechanisms have brought a lot of problems such as high cost and high failure rate while completing the action requirements.

In addition, the existing trolley-type doffing machine cannot work 24 hours a day due to the use of multiple servo motors, which will also affect the doffing efficiency
