Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a color structure changing method in a circular knitting machine when changing the color structure of a knitted fabric during knitting.

(Prior art) Figure 5 (^) is a plan view showing an example of a circular knitting machine;
1) is a side view of the pot 1, in which the pot 1 is placed on the circumference of the cylindrical pot 1.
A plurality of cylinder needles 2 are arranged parallel to the axis of the hook l, a plurality of dial needles 3 are arranged radially from the axis of the hook l in correspondence with each cylinder needle 2, and a plurality of dial needles 3 are arranged radially from the axis of the hook l, and The main body 4 is provided with a plurality of yarn feeders 5 for supplying a predetermined yarn.

Traditionally, knitted fabrics knitted by such circular knitting machines have variations depending on the pattern, but recently there has been an increasing demand for variations depending on the thickness. In order to change the thickness of a knitted fabric, it is necessary to change the color structure, that is, the composition of the yarn used in knitting.

FIG. 6 is a block diagram showing an example of a control device that realizes a color structure change method in a conventional circular knitting machine, and sets data input from the operation panel 11 to the color assignment memory 13 and the yarn feeder selection memory 14. There is also a display/data setting section 12 for displaying the contents of each memory 13 and 14 on the CRT of the operation panel 11, and a color assignment memory! 3, the color assignment section reads out the effective yarn feeder number EJNO from the yarn feeder selection memory 14, stores it in the color data register 16, and outputs this storage completion signal DFIN to the main control section 7; 15. Furthermore, the pattern development section 1
The main control section 17 outputs a start command ST to the main control section 8, and according to the start command ST from the main control section 17, the basic pattern data DB is read out from the basic pattern memory 19 and the pattern is developed. A pattern development section 18 that outputs to the knitting signal generation section 20 and pattern development data DD from this pattern development section 18
DC is compared with the color assignment data C for each number of colors from the color data register 16, and when the DG matches each data DO and C, the editing execution signal ON is output, and when they do not match, the editing execution signal is output. It is composed of a No. 3 generator 20 that outputs a stop signal OFF.

In such a configuration, the color organization is based on color assignment data C
Since it is determined by AD, the color assignment data CAD
The thickness of the knitted fabric can be changed by distributing it to each effective yarn feeder EJNO.

(Problems to be Solved by the Invention) The above-described control device performs various pattern developments using needle pulses and outputs pattern development data to all yarn feeders. Therefore, in order to change the thickness of the knitted fabric, pattern development processing, pattern development data output processing, and color assignment data distribution processing must be performed. However, although these processes require a long time, they have to be carried out with one needle pulse, which has the disadvantage that the knitting speed has to be reduced. Further, there was a problem in that it was not possible to automatically change to an arbitrary color structure from an arbitrary position during knitting.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide a circular knitting system that can automatically change the color structure of a knitted fabric during knitting without reducing the knitting speed. An object of the present invention is to provide a method for changing color structure during knitting in a machine.

(Means for Solving the Problems) The present invention relates to a color structure changing method in a circular knitting machine when changing the color structure of a knitted fabric during knitting. For each knitting course, the color structure and the effective yarn feeder were made to correspond in advance, the knitting course and the yarn feeder during the knitting were determined, and the effective yarn feeder corresponding to the knitting course during the knitting was read out. When the effective yarn feeder includes the yarn feeder in the middle of knitting, the color structure corresponding to the knitting course in the middle of knitting is read out, and the color structure in the middle of knitting is automatically added to the read color structure. This is achieved by changing to .

(Function) The color structure changing method during knitting in the circular knitting machine of the present invention is as follows:
Since the color texture and the yarn feeder are associated with each other depending on the knitting course, the color texture for each yarn feeder can be automatically changed even if the color texture needs to be changed during knitting.

Read out the color allocation number CANO and yarn feeder selection number JSNO from the knitting specification memory 22, and read the effective yarn feeder number EJN among the yarn feeder numbers JNO belonging to this yarn feeder selection number JSNO.
O is read from the yarn feeder selection memory 14, it is determined whether the current yarn feeder number JNO is included in this effective yarn feeder number EJNO, and it is determined whether the current yarn feeder number JNO is included in the effective yarn feeder number EJNO. , the color assignment data C belonging to the previously read color assignment number CANO
AD is read from the color allocation memory 13 and stored in a location in the color allocation register 25 to which the current yarn feeder number JNO is attached, and the current yarn feeder number JNO is set as the effective yarn feeder number E.
If not included in JNO, color assignment register 2
The color allocation control unit 23 sets the location in 5 to which the current yarn feeder number JNO is attached to 0, and outputs a storage completion signal 0FIN to the main control unit 24. Furthermore, using the external needle pulse NP, the knitting course number CNO and yarn feeder number JNO on the current reference point of hook 1 are calculated from the count value of the needle pulse NP and the number of needles between each yarn feeder, and the color is assigned. The main control unit 2 outputs a start command NPST to the control unit 23 and also outputs a start command NPST to the compiling signal generation unit 26 in response to the storage completion signal 0FIN from the color assignment control unit 23.
4, and the start command NPST from the main control unit 24 causes the color allocation data AC from the first yarn feeder to the last yarn feeder to be sent from the color allocation register 25 to 〇C and from the pattern development memory 27 stored in advance. A knitting signal generation unit that compares the pattern development data DD of the data ACADC and DD, and outputs knitting execution No. 4g ON when each data ACADC and DD match, and outputs a knitting unit stopping yarn feeding signal OFF when they do not match. It consists of 26.
