Method for controlling high-speed motion of electronic pattern sewing machine

Abstract

The invention discloses a method for controlling high-speed motion of an electronic pattern sewing machine, which includes: when a spindle servo motor part moves at constant speed, a control system detects motional angle and position of a spindle motor so as to control X-axial and Y-axial motor motion; a scheme of double processing units, namely ARM9 (advanced RISC machine 9) and ARM7, is adopted to separate operation and control of pattern information, and accordingly different controllers can be used for implementing respective specific functions; and the ARM9 operates the pattern data based on a powerful data processing function of the ARM9, the data are transmitted to the ARM7 through a serial line, and the ARM7 can control sewing according to pattern processing results. By means of the double-processing-unit control scheme, control time is well saved, the performances of the control system are improved, sewing speed is increased, the ARM9 processing unit is freed while patter sewing is unaffected, and accordingly other operations are available.

Description

technical field [0001] The invention belongs to the technical field of numerical control, and in particular relates to a control method for high-speed motion of an electronic pattern machine. Background technique [0002] The electronic pattern machine is an indispensable and important sewing equipment in the production process of bags, shoes and hats. In view of the high-speed motion, the three-axis coordinated motion control method it adopts directly affects the performance indicators of this type of electronic pattern machine. [0003] The patent publication number CN 1794561 A discloses a motor motion control method for an electronic pattern machine. Although it realizes the continuous operation of the spindle motor, because the spindle speed of the pattern changes with the different stitches, it is difficult to realize the high-speed and smooth operation of the electronic pattern machine. jitter and other undesirable phenomena. In addition, the technical index that th...

Problems solved by technology

However, it is an integrated control method, which does not separate the operation processing and control, so that the control system cannot realize the parallel operation of operation and control, thus slowing down the speed of the system and reducing the performance of the machine

At the same time, the sewing speed of 800 needles per minute cannot well meet the needs of high-speed electronic pattern machine movement.

[0005] The publication number is CN 101519831A, which discloses a motion control method for computerized pattern sewing machines. Although it can realize the motion control of electronic pattern machines, it also makes up for the lack of high-speed and stable operation mentioned in previous patents, but in the process of coherence However, there is still no solution, overshoot and other phenomena will occur from time to time
