Multi-shaft rotary creel, sample warper and warping method

Abstract

A multi-shaft rotary creel, a sample warper and a warping method are disclosed. The multi-shaft rotary creel comprises: a base body; a main shaft rotatably mounted on the base body so as to project forward, a plurality of supporting shafts rotatably mounted on a forward projecting portion of the main shaft; and a plurality of bobbins mountable on each of the supporting shafts, which is installed opposing to a sample warper with a plurality of yarn guides, and wherein, while the main shaft or each of the supporting shafts rotates in synchronism with rotation of the yarn guides, simultaneous warping of plural yarns by the main shaft or each of the supporting shafts can be performed. Compared with conventional single shaft rotary creel, the multi-shaft rotary creel can further improve the degree of freedom for warping, and can prevent the occurrence of tension fluctuations, and a sample warper (200) and a warping method where warping can be performed efficiently by installing the multi-shaft rotary creel can be provided.

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.
