Description

Automatic design method and system for knitted product

Technical Field

The invention relates to the field of computer aided design, in particular to an automatic design method and system for a knitted product.

Background

Before the knitted product is produced, the pattern and the knitting structure of the product need to be designed in programming software, knitting instructions of a machine are modified, and other information is needed.

The existing programming software interface has stronger specialty and more complicated flow, and is difficult to operate for some users without knitting knowledge. Many times, users need to modify some patterns and structures on the basis of the original design, and cooperation of technicians is needed, so that efficiency is low.

A tool that can automatically generate knitting programs is a good choice for these users. Fig. 1 is a flow chart showing a conventional method for designing a knitted product for a seamless underwear machine and a hosiery machine, and as shown in fig. 1, a designer makes a design file using drawing software.

The width (number of horizontal pixel points) of the design file needs to correspond to the number of knitting needles of the machine, and if different knitting patterns need to be used, different color blocks need to be used for distinguishing.

The design file is a BMP file.

BMP is an abbreviation of english Bitmap, which is a standard image file format in Windows operating system, and can be supported by various Windows applications.

The technician imports the design file (BMP file) into the circular knitting machine programming tool, and converts it into an SDI file that can be recognized by the programming tool.

And filling different PAT files in different color block areas in the SDI file to generate a DIS file.

When a program of a certain knitting pattern (for example, 1-1 tuck pattern) is made, a technician usually selects a template (for example, plain stitch pattern) chain file (XSK file), inserts a new DIS knitting pattern file into the template file, needs to modify instructions (yarn nozzle position, triangle, pattern length and other instructions) of the machine according to the new pattern, saves the new chain file, compiles to generate an on-machine file (XC file) which can be identified by the knitting machine, and copies the on-machine file (XC file) to the knitting machine through a U-disk to knit a product.

Wherein, the SDI file is an identifiable file corresponding to the programming tool;

the PAT file is a pattern file which represents needle selection instructions of the knitting machine, and different colors represent different needle selection instructions;

the DIS file contains needle selection instructions for the knitting machine;

the chain file (XSK file) is an action instruction file operated by each circle of a machine when a sample is knitted, and comprises instructions of yarn nozzle positions, clamps, knitting speeds, yarn feeders, needle pressing motors, knitting patterns, pattern lengths, needle selectors, triangles and the like;

XC file, which is an identifiable file of the knitting machine.

Therefore, the existing knitting programming tool is too complicated, and particularly, when the existing design is modified, conversion of various types of files is involved, and the efficiency is low.

the longitudinal dimension can be designed arbitrarily according to the length of the product.

The knitting structure information represents a knitting structure by color.

The colors in the design file represent needle selection commands on the machine, and different colors represent different needle selection commands of the machine. Different knitting cloth surface effects can be formed by different machine needle selection commands.

Further, the colors used on the seamless underwear machine and hosiery machine are different.

Design file information may be generated from drawing software.

The drawing software may be Adobe Illustrator, often referred to as "AI", a software that applies to industry standard vector illustrations for publishing, multimedia, and online images.

In this embodiment, the design file may be a BMP file or a PNG file.

And S2, inputting the existing knitting program information of the existing product.

Further, the action command includes: the knitting products need yarn nozzles, yarn feeders, cams, density motors and the like.

The current knitting program is edited on Diagraph 3plus software.

In this embodiment, by setting an API interface with the existing Diagraph 3plus software, the knitting program that has been completed in the Diagraph 3plus software can be called as a template program.

And S3, matching analysis.

and analyzing and judging whether the knitting structure of the design file of the new product in the step S1 meets the requirement.

Furthermore, the transverse size of the design file of the new product in the step S1 needs to be consistent with the design file information of the existing product in the step S2, and the longitudinal size has no requirement;

further, the knitting structure of the design file of the new product of step S1 needs to be judged whether it can be recognized, i.e., whether the color used is correct.

If the design file of the new product in the step S1 meets the above two requirements at the same time, the design file information of the new product in the step S1 is matched with the existing knitting program information of the existing product in the step S2, and the step S4 is entered, and the design file of the new product automatically replaces the design file information in the existing knitting program information of the existing product in the step S2.

Taking the design file as a pattern file as an example, the design file of the existing product in step S2 is a template program, and includes one or more pattern files for different parts (lap, bodice, etc.) of the garment.

The different Pattern file numbers in the template program are Pattern1, pattern2 and Pattern3 ….

When a consumer designs a new product, the consumer can select the Pattern of the part to be customized for design, and the designed Pattern files are named as Pattern1, pattern2 and Pattern3 …, so that the Pattern files are matched and replaced with the Pattern files of the existing product.

After the pattern file is replaced, a new program is automatically generated, codes are clicked, and the computer-operating file which can be identified by a machine is generated.

If the file length of the design file of the new product in the step S1 is not consistent with the pattern file in the template program in the step S2, automatically adjusting the pattern length instruction in the step S2, and generating a new knitting program.

And S5, sending the new knitting program information to the knitting machine.

The new knitting program can be sent directly to the machine through the network.

The knitting machines are provided with network interfaces, each knitting machine has an address, and after the user generates the on-machine file, the user selects the machine to which the on-machine file is to be transmitted through the server. No copying by means of USB is required.

And S6, automatically knitting the designed knitted product by the knitting machine according to the new knitting program.

The machine used for knitting the knitting product is a circular knitting machine with computer needle selection, and the designed knitting product can be automatically knitted by starting the machine after the yarn is threaded on the machine.
