Wire arrangement control method based on servo- moto

Abstract

The invention discloses a wire arrangement controlling method based on an actuating motor, which comprises the following steps: using the origin of an absolute value encoder built in an wire arrangement motor as a coordinate system origin and using the deflection angle of the motor with respect to the origin as an independent variable to construct a position coordinate system of the wire arrangement motor; determining the position movement range of a wire arrangement pulley according to the positions at two sides of the inner edge of a wire-winding disc spool and real-time feeding the speed and position information of the wire arrangement motor back to a motion controller, and calculating the command speed of the wire arrangement motor in the next sampling period via the motion controller according to the speed and position information fed back from the wire arrangement motor and the angular velocity fed back from a wire-winding motor. The invention replaces a proximity switch and a variable motor with the absolute value encoder and the actuating motor, so as to remarkably improve the control precision; the spacing position can be randomly set, so as to ensure reliable performance; and the speed tracking control adopts advanced shaftless transmission technology, so that the speed control precision is high, and the wire arrangement is uniform and flat.

Description

technical field [0001] The invention relates to a uniform wire arrangement control method for winding systems such as multi-wire cutting machines and textile machines, in particular to a servo motor-based wire arrangement control method. Background technique [0002] During the operation of the winding system, the wire on the pay-off reel will gradually transition to the take-up reel, so it is necessary to design a wire pulley to evenly wind the wire from the pay-off reel to the take-up reel. The function of the cable pulley is to ensure that the take-up wheel takes up the wire evenly. The schematic diagram is shown in Figure 1. The cable motor drives the cable pulley to reciprocate above the pay-off wheel through the ball screw, and the line is evenly discharged to the take-up wheel. superior. The cable connector must meet the following requirements: [0003] (1) Maximum speed of pay-off wheel: 1000r / min; [0004] (2) Tension requirements: 5N≤F≤50N; [0005] (3) Meter a...
