Rapier machine weft yarn releasing method, computer equipment and storage medium

Abstract

The invention relates to the technical field of textile, in particular to a rapier machine weft yarn unwinding method, computer equipment and a storage medium, and the rapier machine weft yarn unwinding method comprises the following steps: arranging two unwinding rollers between an unwinding spool and a rapier machine, and enabling weft yarns to pass through the space between the two unwinding rollers; a variable frequency motor is used for driving the two unwinding rollers to rotate to actively unwind the weft yarns; acquiring the running speed and the number of rotation turns of a main shaft of the rapier loom, and calculating the length of weft yarns required by the rapier loom; acquiring the perimeter of an unwinding roller and the rotating speed of the unwinding roller, and calculating the actual unwinding weft length of the unwinding roller; and adjusting the rotating speed of the unwinding roller according to the length of the weft yarn required by the rapier loom and the length of the weft yarn actually unwound by the unwinding roller. According to the device, the problems that a large amount of weft yarn is stacked, wound and knotted are solved, the weft yarn meter length needed by the rapier loom is compared with the actual unwinding meter length of the unwinding roller, the rotating speed of the unwinding roller is adjusted in real time, the unwinding linear speed is controlled, and the situation that the weft yarn is snapped and wool yarn is generated is prevented.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a weft yarn unwinding method for a rapier machine, computer equipment and a storage medium. Background technique [0002] Rapier loom, also known as rapier loom, is the most widely used shuttleless loom. In addition to the characteristics of high speed, high automation and high-efficiency production of shuttleless looms, its active weft insertion method has strong varieties. Adaptability, can adapt to the weft insertion of various yarns, and the rapier loom also has obvious advantages in multi-color weft weaving, which can produce yarn-dyed varieties of up to 16 colors of weft yarns. Shuttle looms and rapier looms have become the main types of woven fabrics. [0003] In the prior art, there are two modes for the rapier to pay off the weft yarn. One is to use a DC motor to put a large amount of yarn in the yarn barrel in advance, which will cause the weft yarn to accumulate in a...

Problems solved by technology

[0003] In the prior art, the rapier machine’s weft yarn release method includes two modes, one is to use a DC motor to place a large amount of yarn in the yarn bucket in advance for standby, which will cause a large area of ​​weft yarn to accumulate, and the yarn The yarn is easily entangled together, resulting in knots; the other is the passive unwinding of the yarn tube driven by the rapier machine, so that the yarn is easy to be broken, and the yarn is filtered through the surface of the yarn tube to produce wool yarn, which is easy to knot
