Doffing device with liftable mother car

Abstract

A doffing device with a liftable parent car belongs to the field of doffing equipment of ring spinning frames and comprises a doffing car and the liftable parent car, wherein the doffing car comprises a car body, a suspension mechanism, a travelling mechanism, a bobbin pulling mechanism and a bobbin insertion mechanism; the liftable parent car comprises a car frame, a slide component, an air spring, a second motor and a second transmission mechanism. The doffing device utilizes a subsidiary car and the parent car to separate loading and doffing functions, realizes the functions of automatic travelling, doffing and bobbin insertion, and has an automatic loading function, and the height of the doffing car can be adjusted continuously to adapt to the heights of upper guide rails of spinning frames of different specifications; the degree of automation is high, and the loading and unloading operations are easy; the parent car does not follow the doffing car to travel for doffing, so that the power loss is reduced, and the service life of a battery is prolonged; doffing of all bobbins of a spinning frame is realized by the use of two analog guide rails and false spindles.

Description

technical field [0001] The invention belongs to the field of doffing equipment for ring spinning machines, in particular to a structural design of a doffing device with a liftable mother car. Background technique [0002] The automatic doffing device is a necessary device in the spinning process. This device can replace manual doffing, reduce labor intensity, and improve labor efficiency. With the rising labor costs in recent years, the use and optimization of the doffing device is more urgent and important. . [0003] The automatic doffing device generally has the functions of automatic walking, doffing, intubation, and reversing. Because the device has many functions, the structure is relatively complicated, and the actions of walking, yarn pulling, and intubation have a great impact on the strength and There is a higher requirement for stiffness, making the device heavier. When the traditional automatic doffing device is on the machine, the doffer needs to lift the whol...

Problems solved by technology

[0005] This device has the following disadvantages: ①The height of the upper machine cannot be adjusted: the height of the upper guide rail from the ground is called the height of the upper machine, and the height of the upper machine realized by this device is rigidly fixed and cannot be adjusted continuously; ②It is difficult to adapt to spinning frames of different specifications: This device can only be aimed at the spinning frames with the upper guide rails of the same model and specifications, and for multiple spinning frames with upper guide rails of different heights, the device must replace the upper machine mechanism to adapt; The yarn worker steps on the pedal, tilts, pushes the machine and other laborious operations, which has little effect on reducing the labor intensity; ④The entire additional mechanism for getting on and off the car always follows the doffing car during the doffing stroke, which increases the power loss of the doffing motor; ⑤ It is impossible to automatically doff all bobbins: the first multiple bobbins still need to be doffed manually
