Problems solved by technology

However, since the above-mentioned data of the slub S are random, it is not possible to produce consistent yarns among full bobbins.
As a result, there is a problem that the reproducibility of the cloth woven with this special yarn cannot be guaranteed

no. 1 approach

[0012] Next, according to Figure 1 to image 3 A first embodiment will be described which embodies the present invention as a special yarn manufacturing apparatus that forms slubs by shifting the front rollers. Figure 1 is a block diagram of a special yarn manufacturing device, figure 2 It is a partial schematic diagram of a special yarn.

[0013] The special yarn making unit is basically the same as the ring spinning machine. As shown in FIG. 1 , the spindle 1 is driven to rotate by a spindle drive system, which includes: a drive pulley 3 driven by a motor 2 , a driven pulley 4 , and a tangential transmission belt wound between the two pulleys 3 and 4 5. As the motor 2, a variable-speed motor driven via an inverter 6 is used, and has a rotary encoder 2a. The main shaft 7 is rotatably arranged along the spindle row. Elevating assemblies 10 (only one shown in the figure) are arranged on the main shaft 7 at predetermined intervals, and the elevating assemblies 10 connect a ...

no. 2 approach

[0045] Next, the second embodiment will be described. In this embodiment, the CPU 24 decides to read out the pattern weave data A1, A2...A(n-1), An and the pattern weave data B1, B2...B( It differs from the above-described first embodiment in that the order of k-1) and Bk is different, and the number of pattern weave data in the pattern weave tables 40A and 40B can be the same. The other structures are the same as those of the above-described first embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or abbreviated.

[0046] In this embodiment, when the number of pattern weave data in each of the pattern weave tables 40A and 40B is different, each pattern weave data is sequentially and alternately read from each of the pattern weave tables 40A and 40B according to the same rules as in the first embodiment. A1, A2...A(n-1), An and pattern structure data B1, B2...B(k-1), Bk. ...

Abstract

The special yarn manufacturing apparatus of the present invention performs the speed change of the front roller based on a plurality of pattern data indicating changes in the thickness of the spun yarn, and manufactures a special yarn corresponding to the above pattern data including at least information on the distance between thick pitches. Wire. The CPU controls the first servomotor in accordance with an execution program for executing a repeating pattern of one cycle consisting of pattern data larger in number than the pattern data based on the pattern data stored in the working memory. , thereby spinning a spun yarn that performs a repeated pattern structure of one cycle.

Description

technical field [0001] The present invention relates to a special yarn manufacturing device, in particular to a special yarn manufacturing device for manufacturing (spinning) a special yarn whose yarn thickness is not constant but varies, which is called a slub Yarn or fancy yarn. Background technique [0002] Conventionally, there has been a special yarn called a slub yarn or a fancy yarn in which the thickness of the spun yarn is not constant but is locally formed thicker. like figure 2 As shown in the figure, a special yarn (slub yarn) SY is manufactured, and the thickness (thickness D), length (thick length L) and interval (between thick segments) of the thick segment S (thick yarn part) Spacing P) varies. To manufacture this special yarn, a fine spinning machine having the same basic structure as that of a ring spinning machine, and a front roller and a rear roller of the drafting section (drafting device) can be independently driven at variable speed, respectively. ...
