A comb lateral movement control system and control method for a warp knitting machine

Abstract

The invention provides a pattern guide bar horizontal movement control system for a warp knitting machine. The pattern guide bar horizontal movement control system comprises an industrial personal computer, a horizontal movement controller, an optical-electricity encoder, an SU driver and an SU mechanical position device. The optical-electricity encoder is used for determining position information of a spindle of the warp knitting machine and transmitting the position information to the horizontal movement controller. The horizontal movement controller is provided with a data communication interface used for receiving process data downloaded from the industrial personal computer. The SU driver is used for converting the process data transmitted by the horizontal movement controller into an electric control signal and driving and controlling the SU mechanical position device to act. The horizontal movement controller is connected with the SU driver through optical fibers. According to the pattern guide bar horizontal movement control system for the warp knitting machine, since the optical fibers are arranged between the horizontal movement controller and the SU driver for communication, the data transmission speed of the system is increased, the system is good in stability and high in anti-jamming capability, and the number of device hardware can be reduced by about 70%; besides, after the optical fiber communication technology is integrated, only a small number of optical fiber cables are used for simple connection between all parts, and therefore maintainability is improved greatly.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a control system and a control method for patterned comb lateral movement of a warp knitting machine. Background technique [0002] A warp knitting machine is a knitting machine that weaves warp yarns arranged in parallel into a warp knitted fabric. The warp knitting machine is mainly composed of a knitting mechanism, a bar traverse mechanism, a let-off mechanism, a pulling and coiling mechanism and a transmission mechanism. The function of the bar traversing mechanism is to make the bar move laterally according to the requirements of the knitted fabric during the loop forming process, and place the warp yarns on the needles, so as to weave a knitted fabric with a certain structure. [0003] For now, the bar traversing mechanism generally includes a mechanical bar traversing mechanism and an electronic bar traversing mechanism. Since the invention of the first tricot warp knitt...
