Flat knitting machine yarn nozzle control self-running yarn nozzle servo system and method thereof

Abstract

The invention discloses a flat knitting machine yarn nozzle control self-running yarn nozzle servo system and a method thereof. The system comprises a machine head and several yarn nozzles. The machine head is connected to a first servo motor. The first servo motor is connected to a main control module and an encoder. The encoder is connected to the main control module and an encoder decoding device. Each yarn nozzle is connected to a second servo motor through a synchronous belt. The encoder decoding device is connected to a yarn nozzle control system and each second servo motor through a data transmission line. The yarn nozzle control system is connected to each second servo motor. Yarn nozzle motion efficiency s high, a stopping position is accurate and there are other advantages.

Description

technical field [0001] The invention belongs to the technical field of yarn feeder control of a flat knitting machine, and in particular relates to a yarn feeder control self-running servo system of a flat knitting machine and a method thereof. Background technique [0002] Such as figure 1 As shown, the head of the flat knitting machine in the prior art is equipped with a yarn feeder device controlled by an electromagnet. When the yarn feeder needs to move, the electromagnet is laid down, the machine head is mechanically connected with the yarn feeder, and the yarn feeder and the machine head move synchronously. . When the yarn feeder does not need to move, the electromagnet is turned on, the machine head is disconnected from the yarn feeder, and the yarn feeder stops moving. The yarn feeder servo system in the prior art has the following disadvantages: [0003] a. The yarn feeder is mechanically connected with the machine head, and when the machine head drives the yarn ...

AI Technical Summary

Problems solved by technology

[0007] The above scheme uses two types of servo motors: the first servo motor and the second servo motor to drive the movement of the machine head and the yarn feeder respectively, thereby reducing the inertia of the machine head and reducing the idling time of the machine head, which solves the aforementioned problems to a certain extent. There are some technical problems, but the above-mentioned technical solution still has defects, such as the structure of the above-mentioned solution is too complicated, and the first servo motor and the second servo motor of the above-mentioned technical solution separately control the movement of the machine head and the yarn feeder, and there is no gap between the two. Communication connection, the yarn feeder cannot obtain the current position information of the machine head, which brings difficulties to the synchronous movement of the two
