Doffing parent-subsidiary car device with four-bar lifting mechanism

Abstract

A doffing parent-subsidiary car device with a four-bar lifting mechanism belongs to the field of doffing equipment of ring spinning frames and comprises a doffing car and a 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 rotating component, an air spring, a second motor and a second transmission mechanism. The device utilizes the parent car and the subsidiary car to separate loading and doffing functions, realizes 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, and in particular relates to the structural design of a doffing car device with a four-link lifting mechanism. 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 dof...

AI Technical Summary

Problems solved by technology

[0005] The device has the following disadvantages: (1) The 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; (2) It is difficult to adapt to different Specification spinning frame: This device can only be used for spinning frames with the same model and specification, that is, with the same height of the upper guide rail. For multiple spinning frames with different heights of the upper guide rail, the device must be replaced by the upper mechanism to adapt; (3) Automation The degree is not high: the doffing worker needs to step on the pedal and tilt, push the machine and other strenuous operations, which has little effect on reducing the labor intensity; (4) The entire additional mechanism for getting on and off the car always follows the doffing car during the doffing stroke, increasing The power loss of the doffing motor is reduced; (5) It is impossible to automatically doff all bobbins: the first multiple bobbins still need manual doffing
