Problems solved by technology

However, for weaving products with large pattern changes and high complexity, the yarn feeding speed of the weft feeder obviously cannot keep up with the weaving speed, resulting in a passive situation of the weft feeder, which seriously hinders the weaving speed of the loom and affects production efficiency

Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0022] The present invention can be reformed and formed on the existing loom. The components involved in the present invention mainly include a color selection control unit 1 and a plurality of weft feeder microcontrollers 2 .

[0023] The color selection control unit 1 can be a central processing unit provided in the numerical control system of the loom itself, or a processing chip can be used separately and placed under the numerical control system. The specific internal circuit structure and modules of the color selection control unit 1 are already in the technical category of the numerically controlled loom, so no further description will be made here.

[0024] The weft feeder single-chip microcomputer 2 is an integral part of the weft feeder itself, which can be directly programmed and processed in the present invention, and the k...

Abstract

The invention discloses a control system and a control method for the pattern precognition of weft accumulators. The control system comprises a color selection control unit and a plurality of weft accumulator singlechips, wherein the weft accumulator singlechips are connected with the color selection control unit so as to maintain data communication. The control method comprises the following steps that: pattern data obtained by encoding flower forms are stored in the color selection control unit, the color selection control unit sends a pattern data fragment with certain digits to each weft accumulator singlechip at regular intervals, the singlechip on each weft accumulator reads pattern data, performs encoding analysis on the pattern data, and acquires a flower form code which is the same as a code of the weft accumulator, and the weft accumulator actively performs weft accumulation according to the quantity and time that the flower form code appears. By the control system and the control method, the passive weft accumulation of the weft accumulators can be converted into the active weft accumulation, so that the weft insertion rate of the weft accumulators is improved, the overhigh fluctuation of the speed of weft accumulation motors is furthest reduced in the weaving of complicated patterns, the stability of the weft accumulation capacity and the output tension is maintained, and the powerful guarantee is provided for the high-speed and high-efficiency development trend of modern looms.

Description

technical field [0001] The invention relates to a pattern control technology of a weft feeder and a loom, in particular to a control system and a control method for pattern prediction of a weft feeder. Background technique [0002] With the development of textile technology, the patterns and patterns of knitted fabrics are becoming more and more complex, which puts forward stricter requirements for processing enterprises in the textile field. [0003] In the existing loom with a weft feeder, during the weaving process, the weft thread will be pre-wound to the weft feeder to be used for yarn feeding. One weft feeder for one color of weft yarn. The loom selects weft yarns of different colors for weaving according to the flower-shaped design of the flower-shaped board. The amount of yarn stored in the weft feeder has nothing to do with the pattern, but only with the amount of weft storage set in the weft feeder itself. In this traditional way, for weaving products with low p...
