Embodiment Construction

[0076] see Figure 1-Figure 4 As shown, the high-speed motion control method of the direct-drive industrial sewing machine provided by the present invention improves the sewing speed and sewing effect by dynamically adjusting the cloth feeding time of the X-axis and Y-axis of the sewing machine, mainly under the condition of not feeding cloth, manually Determine the angular relationship between the up and down movement of the needle bar, the up and down movement of the main shaft and the encoder during the sewing process, and the control method is realized through the following steps,

[0077] Step 1. Turn each axis of the sewing machine to the initial zero position; the needle point A of the needle bar 1 is at the initial zero position, and the distance between the needle point A and the needle plate is 15mm. At this time, the turntable reference line 4 of the sewing machine main shaft encoder 3 is in a vertical position, and the turntable reference line 4 coincides with the ...

Abstract

The invention provides a method for controlling high-speed running of a direct drive industrial sewing machine. The method comprises the step of determining the relation between the needle bar up-and-down moving and sewing process and up-and-down moving of a main shaft as well as the angle of an encoder under the condition of not conveying cloth, and particularly the method realizes the purpose of improving the sewing speed and sewing effect through dynamically adjusting the cloth conveying time of the X shaft and Y shaft of the sewing machine. By using the method, the problems that in the existing control method, the patterns are reduced when a thick fabric is sewn and the sewing efficiency is low can be solved, and the sewing efficiency is further improved on the premise of guaranteeing the sewing quality.

Description

technical field [0001] The invention relates to a control method of a sewing machine, in particular to a high-speed motion control method of a direct-drive industrial sewing machine. Background technique [0002] Special sewing machines such as electronic knotting machines and electronic pattern machines are indispensable processing equipment in the production process of clothing, bags, shoes and hats. At present, the control method adopted by special sewing machines is to detect the encoder signal of the spindle motor while the spindle servo motor is rotating, and then control the movement of the X-axis and Y-axis to feed materials according to the angle of the spindle motor. Due to the fixed feeding angle, when the spindle of the special sewing machine is moving at high speed, the pattern will be reduced when sewing thick materials, or the sewing speed cannot be increased in order to ensure the sewing quality of the pattern, which affects production efficiency.
