Problems solved by technology

It can be seen that the warp knitting machine electronic sway control system using the electronic cam control algorithm provides better dynamic characteristics and more precise master-slave shaft cam tracking characteristics in the high-speed production process, but also gives the system accurate control after power failure. Sequel processing poses greater difficulties

Embodiment 1

[0033] This embodiment provides a method for controlling electronic traversing jacquard power-off continuation for warp knitting machines. The method includes:

[0034] Step 1: Record and store the current process row number of each yarn guide bar, as well as the spindle angle position before the electronic traverse jacquard control system is powered off;

[0035] Step 2: After the electronic traversing jacquard control system is powered on, read the current spindle angle position of the warp knitting machine from the system spindle encoder, compare the spindle angle position before the system is powered off, and judge whether the angle difference between the two is within the predetermined range ;

[0036] Step 3: If the result of the judgment in step 2 is that the angle difference between the two is within the predetermined range, then the current spindle angle position of the warp knitting machine, and the range of needle traverse angles set by each guide bar and the needle...

Embodiment 2

[0044] This embodiment provides a method for controlling electronic traversing jacquard power-off continuation for warp knitting machines, see figure 1 and figure 2 , for the total number of guide bars is A (1≦A≦33), the current process flower height is H (1≦H≦10000), and the pulse equivalent output by the encoder per spindle revolution is P (1≦P≦10000) , the servo motor pulse equivalent corresponding to the digital traversing of one needle pitch from the axis guide bar is K (1≦K≦1000), and the i (1≦i≦A) guide bar in the current process row L 1 (0≦L 1 ≦2), the number of needle back traversing lap yarn in the current process row of the i-th guide bar is L 2 (0≦L 2 ≦17), using linear acceleration for acceleration / deceleration of the electronic cam master-slave axis position relation motion equation f() expression is S=(a / 2)×t 2 (S is the position coordinate of the pulse track of the slave axis, a is the constant acceleration value in a certain cam motion segment, and t is ...

Abstract

The invention discloses an electronic traverse jacquard power-off continuation control method for a warp knitting machine, and belongs to the technical field of warp knitting equipment. Through complete control method design, software of a control system is guided; an electronic cam coupling data pair of a certain traverse motion segment finished by the a main / auxiliary shaft before the system ispowered down can be actively reversely solved only by reading a current actual physical angle position of the main shaft after the system is powered on and the relevant process data records in the system, and an electronic cam coupling data pair required to complete the remaining cam track of the traverse motion segment after the main shaft starts rotating is calculated, that is, reverse calculation of the electronic cam data pairs on the electronic cam motion track before and after 'breakpoint' is completed in the software actively after the system is powered on, thereby solving the problem of breakpoint continuation of a warp knitting machine electronic traverse control system using an electronic cam control algorithm after power-off restart.

Description

technical field [0001] The invention relates to an electronic traverse jacquard power-off continuous knitting control method for a warp knitting machine, which belongs to the technical field of warp knitting equipment. Background technique [0002] As a flexible jacquard control method, electronic traversing jacquard uses the combination of yarn threading methods between different guide bars on the warp knitting machine, and cooperates with the flexible and changeable laying movement of each guide bar. Form rich and unique electronic traverse jacquard warp knitting products on the surface. At the same time, because the electronic traversing mechanism uses a servo motor to replace the original warp knitting guide bar to realize the necessary flower plate chains and face cams of jacquard, it can eliminate the influence of the pattern richness and process flower height design of warp knitting jacquard products. While the length of the plate chain block and the size of the face...
