Embroidery machine frame movement control method and system

Abstract

The invention provides an embroidery machine frame movement control method and system capable of improving frame movement efficiency and movement precision. The invention discloses an embroidery machine frame movement control method. The method specifically comprises the following steps: determining an original point of a machine; fixing a negative limit sensor; fixing a positive limit sensor; calculating an embroidery range of the embroidery machine according to the positive limit position and the negative limit position; reading parameters of patterns needing to be embroidered through a control device; setting an embroidery starting point; moving the frame according to the pattern parameters to carry out embroidery, and writing the number of stitches in the pattern and an absolute coding value corresponding to the current coordinate position information Ln into a control device every time one stitch in the pattern parameters is completed; and determining whether the absolute coded value of the current motor controller is consistent with the absolute coded value recorded by the control device when the needle is finished finally before shutdown, and controlling the framework to return to an embroidery stopping point by the control device to execute subsequent pattern embroidery. According to the invention, the remodeling efficiency is improved, and the frame movement execution speed of the embroidery machine is improved.

Description

technical field [0001] The invention relates to a control method for an embroidery machine, in particular to a method and a system for controlling the movement of an embroidery machine frame, and belongs to the technical field of embroidery machines. Background technique [0002] The existing embroidery machine frame drive system consists of a servo motor and two limit switches, and the servo motor adopts an incremental encoder. Specifically, it takes a limit switch as the origin, and through the feedback of the encoder of the servo motor, the drive frame moves to a certain position after software calculation, but there are the following disadvantages: First, because of production needs, it is necessary to adjust the limit switch frequently After each position adjustment, the saved position parameters will deviate, and all patterns need to be repositioned; secondly, when the machine is turned off, the frame cannot recognize the current position after the frame moves, and it ...

AI Technical Summary

Problems solved by technology

Specifically, a limit switch is used as the origin, through the encoder feedback of the servo motor, the drive frame moves to a certain position after software calculation, but there are the following disadvantages: First, due to production needs, the limit switch needs to be adjusted frequently position, and after each position adjustment, the saved position parameters will deviate, and all patterns need to be repositioned; second, when the embroidery machine is turned off, the current position cannot be recognized after the frame moves, and it must be restarted every time it is turned on again. For the position, the patterns often appear out of shape and lead to scrapping; third, if the power is suddenly cut off during the embroidery process, manual positioning must be performed, otherwise there will be scrapping of the pattern out of shape; fourth, the current control system cannot cover the entire frame It is impossible to automatically judge whether the embroidered pattern will exceed the range of the embroidery frame; fifth, the position of the origin of the pattern will shift after a long time, and it is often necessary to re-calibrate after switching between different patterns, resulting in a long time for pattern change
