Multi-shaft rotary creel, sample warper and warping method

Abstract

A multi-axis rotary creel, a sampling warping machine, and a warping method, a multi-axial rotary creel, comprising: a base body; A plurality of fulcrums rotatably arranged on the front protruding portion of the main shaft, and a plurality of bobbins mounted on each of the fulcrums; and arranged opposite to a sampling warping machine with a plurality of yarn guides; The main shaft or each fulcrum rotates in synchronization with the rotation of the yarn guide, while simultaneously warping a plurality of the main shafts or each fulcrum simultaneously with the main shaft. Compared with the conventional single-axis rotary creel, this multi-axis rotary creel can further improve the degree of freedom of warping, and can provide a new multi-axial rotary creel that can prevent uneven tension and is provided with the Multi-axis rotary creel, sampling warping machine for more efficient warping and warping method thereof.

Description

technical field [0001] The invention relates to a multi-axis rotating creel suitable for a sampling warping machine, a sampling warping machine with the multi-axis rotating creel and a warping method. The sampling warping machine has the function of winding yarn on Multiple yarn guiding mechanisms of the warping cylinder automatically change yarns according to predetermined pattern data (yarn sequence), and wind the yarns on the warping cylinder. Background technique [0002] As a sample warping machine used in the past, for example, the structure disclosed in the well-known patent document 1, that is, a fixed creel that upright supports a plurality of bobbins wound with yarns of different types (different colors or different twists), According to the predetermined pattern data (yarn order), the yarn is changed by the yarn selection device and the yarn is wound on the warping cylinder by the yarn guide. [0003] In addition, it is well known that there is also such a sample...

AI Technical Summary

Problems solved by technology

[0009] However, on the sample warping machine described in Patent Document 7, which combines a plurality of rotary creels on a plane and can flexibly perform pattern warping and repeated warping, due to the position of the warping cylinder and each rotary creel Offset, so the distance or angle between the bobbin and the yarn guide at the front end of the yarn guide is uneven due to the rotary creel used

Therefore, the tension of the yarn pulled out from the bobbin and wound onto the warping cylinder through the yarn guide at the front end of the yarn guide may be uneven, and tension unevenness may sometimes occur.
