Method and system for controlling alternating movement of central shuttle

Abstract

The invention discloses a method and a system for controlling the alternating movement of a central shuttle. The method comprises the following steps of: judging whether the advancing direction of the pattern which is embroidered as the first needle is a positive direction or a negative direction; counterclockwise rotating the central shuttle if the advancing direction is a positive direction; inthe first needle, clockwise rotating the central shuttle for 360 degrees to twist the embroider line and then clockwise rotating the central shuttle for 90 degrees to embroider the second needle according to the condition that the advancing direction of the pattern is positive direction; in the second needle, counterclockwise rotating the central shuttle for 360 degrees to retire the embroider line and then counterclockwise rotating the central shuttle for 90 degrees to finish the chain-type embroidery through the central shuttle alternating movement in the first and the second needles. The invention solves the technical problems of high requirement on mechanical load of a central shuttle motor and great workload of a central shuttle shaft in the traditional method for controlling the double-movement of the central shuttle, thereby achieving the purpose of improving the production efficiency of a computer embroidery machine, the stability of the whole chain type computer embroidery machine and the quality of the embroidery during high-speed embordering.

Description

technical field [0001] The invention relates to automatic control technology, in particular to a method and system for controlling the alternate movement of ring shuttles used in high-speed chain computerized embroidery machines, and belongs to the technical field of automatic control. Background technique [0002] With the in-depth study of automatic control technology in the textile industry, computerized embroidery machines were born, among which chained computerized embroidery machines are widely used in the industry due to their superior performance. [0003] In the prior art, the ring shuttle control system is a key component of the chain computer embroidery machine, which is directly related to the chain sewing of embroidery. The working efficiency and stability of the ring shuttle control system directly affect the quality of the chain embroidery and the production efficiency of the chain computer embroidery machine. The loop shuttle control system mainly includes a...
