Embodiment Construction

[0016] At present, before weaving 3D patterns, the domestic mainstream seamless underwear machines require the master plate maker to reduce the speed to 70 rpm in advance in the editing pattern chain, so as to achieve a good 3D pattern effect. The high-speed 3D knitting method of the seamless underwear machine in the present invention will be specifically described below.

[0017] like figure 1 , figure 2 As shown, the high-speed 3D knitting method of the seamless underwear machine in this embodiment includes the following steps:

[0018] S1. After the pattern data is loaded, the control system of the underwear machine pre-reads the needle cylinder speed (unit: revolution / minute) in the fabric chain and records it;

[0019] S2. The control system of the underwear machine pre-reads the operation command of the density motor in the fabric chain, including the action position of the density motor, the travel direction of the density motor and the travel value of the density mo...

Abstract

The invention relates to a high-speed 3D (three-dimensional) knitting method for a seamless underwear making machine. By the high-speed 3D knitting method for the seamless underwear making machine, the problems that instructions are delayed to be sent by a control system and running instructions are delayed to be executed by a density motor are solved, and the production efficiency is improved. According to the technical scheme, the high-speed 3D knitting method comprises the following steps of reading the revolving speed of a needle barrel and the running instructions of the density motor in advance by using the control system of the underwear making machine; calculating the timing advance value of running instructions sent to the density motor by using a formula of the timing advance value= the revolving speed of the needle barrel* delayed time* the total number of needles of the needle barrel; calculating the new position value of the running instructions sent to the density motor according to the timing advance value; updating pattern data by using the new position value as an actual position value of the running instructions transmitted to the density motor; carrying out knitting actions by using the underwear making machine; transmitting data of the running instructions to the density motor by using the control system when the underwear making machine reaches the actual position where the running instructions are transmitted; and performing 3D knitting. The high-speed 3D knitting method for the seamless underwear making machine is used for the field of control systems of seamless underwear making machines.

Description

technical field [0001] The invention relates to the technical field of control systems for seamless underwear machines, in particular to a high-speed 3D knitting method for seamless underwear machines. Background technique [0002] The realization of 3D weaving of seamless underwear machine is through the continuous reciprocating rotation of the density motor, so that the density of the fabric alternates between elastic and tight, so as to achieve a 3D effect with uneven fabric patterns. The position of the 3D structure and other pattern structures in the fabric is determined, which needs to be consistent with the running position of the seamless underwear machine and the density motor. Because the control system sends commands to the density motor, and then the density motor executes the operation command, there is a delay. If the underwear machine runs at high speed, the delay phenomenon will cause the problem of the 3D pattern shifting backward. [0003] Therefore, in or...
