Method for controlling the motion of computerized pattern sewing machines

Abstract

The invention provides a method for controlling the motion of computerized pattern sewing machines. The method is that a controlling system controls the feeding movement of an X-axis and a Y-axis by dThe invention provides a method for controlling the motion of computerized pattern sewing machines. The method is that a controlling system controls the feeding movement of an X-axis and a Y-axis by detecting the angle of a spindle servo motor when the spindle servo motor is running uniformly. An industrial controlling computer and a Field Programmable Gate Array (FPGA) process and control the movetecting the angle of a spindle servo motor when the spindle servo motor is running uniformly. An industrial controlling computer and a Field Programmable Gate Array (FPGA) process and control the movement respectively, i.e., the data operated by CPU is stored in sequence in an array provided by the FPGA and the FPGA fetches and controls the data in the array in sequence. The computer and the FPGAement respectively, i.e., the data operated by CPU is stored in sequence in an array provided by the FPGA and the FPGA fetches and controls the data in the array in sequence. The computer and the FPGArun at the same time thus greatly saving controlling time and raising the sewing speed. The computerized pattern sewing machines adopting the method has the advantages of high speed, smooth operation run at the same time thus greatly saving controlling time and raising the sewing speed. The computerized pattern sewing machines adopting the method has the advantages of high speed, smooth operation, low noise and beautiful and even stitch. The method is applicable to the motion control of the current computerized pattern sewing machines or other similar industrial sewing machines., low noise and beautiful and even stitch. The method is applicable to the motion control of the current computerized pattern sewing machines or other similar industrial sewing machines.

Description

technical field [0001] The invention relates to a motion control method in the field of numerical control, in particular to a motion control method for a computerized pattern sewing machine. Background technique [0002] Pattern sewing machine is an indispensable and important sewing equipment in the production process of bags, shoes and hats. The motion control method adopted by the computerized pattern sewing machine directly affects the performance index of the computerized pattern sewing machine. [0003] The Chinese patent document with the publication number CN1794561A discloses an invention patent application technology entitled "Electronic Pattern Sewing Machine Motor Motion Control Method", which discloses an electronic pattern sewing machine motor motion control method. Although this method realizes the continuous operation of the main shaft motor, the speed of the main shaft motor must be changed when each stitch is sewn. Such a control method is difficult to ach...
