Embodiment 1

[0045] Embodiment 1: The multi-servomotor synchronous control of the main machine of the knitting machine of the present invention includes a servomotor synchronous control system and a control method based on the servomotor synchronous control system.

[0046] The servo motor synchronous control system includes: control panel, PLC and servo drive device. The control panel is connected to the input terminal of PLC to set the internal parameters of PLC; the output terminal of PLC is connected to the servo drive device to control the servo drive device to drive the knitting machine. run and speed.

[0047] The said servo drive device is no less than two sets with the same structure; including: a servo drive and a servo motor, the output end of the servo drive is connected to the servo motor to form a set of servo drive devices, and the servo drive drives the servo motor to run;

[0048] The two sets of servo drive devices include: a first servo driver KQ1, a second servo driver ...

Embodiment 2

[0070] Embodiment 2: This embodiment discloses a synchronous control system that controls no less than two sets of servo drive devices to drive the normal operation of the knitting machine. When the load of the knitting machine is too heavy, the use of two sets of servo drive devices cannot meet the normal operation of the machine , the synchronous control system of the present invention can be expanded to use three servo drive devices to run synchronously, or to use more sets of servo drive devices to run synchronously.

Abstract

The invention discloses a knitting machine host multi-servo-motor synchronous control system and a control method, and belongs to knitting machine control systems. A control panel of the control system is connected with the input end of a PLC and is used for setting internal parameters of the PLC and controlling the operation and the operation speeds of servo motors; the output end of the PLC is connected with the input end of a first servo driver KQ1 and the input end of a second servo driver KQ2, the output end of the first servo driver KQ1 and the output end of the second servo driver KQ2 are connected with a first servo motor SM1 and a second servo motor SM2 respectively, and the PLC respectively controls the first servo motor SM1 and the second servo motor SM2 to operate through the first servo driver KQ1 and the second servo driver KQ2; and the first servo motor SM1 and the second servo motor SM2 are meshed with a host drive plate gear through a motor transmission gear to drive aknitting machine host to operate. The system and the method have the advantages that the motors of the knitting machine are adjusted to operate normally at a rated speed, yarns can be replaced in a non-stop state, knitting operation is facilitated, the quality and yield of products are stably improved, and waste of the products is reduced.

Description

technical field [0001] The invention relates to a knitting machine control system, in particular to a knitting machine host multi-servo motor synchronous control system and a control method. Background technique [0002] There are more and more types of knitting machines, the number of knitting machines has increased from dozens of spindles to hundreds of spindles, and the development of small knitting machines to large knitting machines has become more and more extensive. Especially in the field of national defense and military industry, marine cables, and carbon fiber fields, large-scale braiding machines are mostly used. [0003] At present, large-scale knitting machines have a large machine running surface, and the machine has a lot of resistance during operation. If a high-power motor is used for single-point transmission, it will cause failure at the transmission point due to excessive force; if a high-power motor with a transmission mechanism is used Dispersed into m...
