An apparatus for directionally arranging blank tubes of an automatic doffer

Abstract

Provided is an apparatus for directionally arranging blank tubes of an automatic doffer and relates to the field of spinning machinery. Artificial doffing and tube sleeving is basically applied to the prior ring spinning frame, causing high labor intensity and low efficiency. The apparatus comprises a hollow box body with openings on both the top and the bottom thereof. A pair of projections, which are mounted on both the left and the right sides of the interior of the top opening, forms a crack with the width less than the diameter of the large end of one blank tube but slightly greater than the small end of the same, and the width of the middle part of the top opening is greater than the diameter of the large end of the blank tube. A concave arc surface is formed by the out-extending left sidewall of the box body. A shunting and guiding mechanism, which is mounted in the inner chamber of the box body, is connected with the top opening at the middle part thereof and divides the inner chamber of the box into a left channel and a right channel. A horizontal baffle is mounted at the bottom opening of the box body. The apparatus, which achieves the automatic u-turn of the blank tubes, satisfies the requirement that the large ends and small ends of the blank tubes are arranged towards same direction when the ring spinning frame performs automatic sleeving so that the directional arrangement for the ring spinning frame under automatic sleeving is achieved, labor intensity of workers and labor cost are reduced, and production efficiency is enhanced.

Description

technical field [0001] The invention belongs to the field of spinning machinery, and in particular relates to an orientation arrangement device for empty tubes of an automatic doffing machine. Background technique [0002] At present, most of the ring spinning machines on the market still adopt the manual doffing method, that is, after the yarn is fully wound, the full bobbin is manually removed from the spindle of the spinning machine one by one, and then Replace the empty tube. Since the bobbin rotates with the spindle at high speed, there will be a large adhesive force between the bobbin and the spindle bar, and manual doffing is labor-intensive and inefficient. The development of automatic equipment to realize automatic doffing and automatic sleeve is the technical trend of the spinning industry. Since the empty tube has a distinction between the large and small ends, the automatic sleeve requires the empty tube to be arranged in a single direction, and the empty tube...
