Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of perforating patterned paper for jacquard in which the same pattern is repeatedly woven.

Generally, when punching pattern paper for Jia cards, a single design drawing is created, and an automatic reading device such as a pattern analyzer uses an automatic reading device such as a pattern analyzer to color-code the design drawing for each different structure, and then reads the design drawing into a color discrimination device. The color discrimination signal from the color discrimination device is converted into a tissue signal corresponding to each color of the design drawing, the converted tissue signal is extracted in the form of perforated tape, and the perforated tape is used to electrically and automatically print the pattern paper. A method is used in which a perforation machine is operated to perforate one piece of paper.

However, in the above-mentioned method of perforating patterned paper, one patterned paper corresponding to one design drawing is perforated, and the pattern to be woven is selected from the design drawing,
If the selected pattern is to be repeatedly perforated on the pattern paper, a new design must be created from the design drawing of the selected pattern, which requires a lot of time and effort.

The present invention has been made based on the above point, and a microcomputer is connected to the pattern paper perforation machine, and various knitting command information is input to the microcomputer, and tape signals of the perforated tape of the overall design drawing are input to the microcomputer. There is no need to create a new design for the design selected from the overall design drawing, and the calculation process is performed according to the formation command information, the desired design is selected, and the selected design is printed on the pattern paper. To provide a method for perforating pattern paper for jia cards, which enables repeated perforation.

The present invention will be explained in detail below based on the drawings.

Figure 1 shows a microcomputer (hereinafter referred to as the microcomputer) connected to the pattern paper perforation machine. By inputting various knitting command information into the microcomputer, the perforated tape is extracted by deciphering the design drawing. The information is input into the microcomputer and various patterns are automatically created according to the composition command input.The data memory DM stores the information input from the data input block DI and the information input from the block DI is used. It consists of program memories PG and M that store programs, and a calculation unit CPT that calculates and organizes information according to the program.The output from the microcomputer MCPO is converted to an output signal such as an electrical signal via an output conversion block DO. is output.

Figure 2 shows the pattern paper perforation method in the present invention, and the overall design P1 is the partial design P-1a, P-1.
b, and the perforated tape t has the above design P1.
is converted as a tape signal.

Now, when perforating partial design P-1a of design P1 as a patterned paper PC to be repeatedly woven twice like design P2, the perforated tape t is input into the microcomputer via the tape reader TR, and the data is stored in the data memory.
Remember it in DM.

On the other hand, the first master tape MT1 records information for reading only partial design P-1a of design P1.
and the read partial design drawing P-1a on paper.
The second part recorded the information to instruct the PC to repeat drilling.
The command information of the master tape MT2 is input to the microcomputer MCOP via the tape reader TR, and is stored in the program memory PGM.

When the command information of the master tapes MT1 and MT2 is input to the microcomputer MCOP, the tape signal of the partial design P-1a is transmitted to the partial design P-1a.
Comparison circuit 1 is used as a signal for one weft (L/2) of
01 is input. In other words, the comparator circuit 10 issues a knitting command to repeat 1/2 of one weft length L of design P1 (one weft length of partial design P-1a) twice.
1, the data is formatted.
Organized in DFT, out data area
It will be stored in ODA in a relocated form and will await the next command.

Furthermore, the out-timing circuit 102 confirms that the pattern punching machine PM is operable, and the punching information in the out data area ODA is output all at once, and the solenoid 18 of the pattern paper punching machine PM shown in FIG. 3 is activated. .

The operation of the paper perforator PM will be described below.

Fig. 3 shows a pattern paper perforator, in which one end of a control plate 2 arranged in parallel and at equal intervals for the number of punches is pivotally fitted to a support shaft 1 extending in a direction perpendicular to the plane of the drawing. A memory needle 3 is hooked and suspended in the long groove 4 of the upper edge opening of the control plate 2, and a press bar 6 is supported horizontally through a hole 5 formed in the middle portion of the memory needle 3. At this time, the memory needle 3
is engaged in a vertically movable manner within the long groove 4, and is normally located at the bottom of the long groove, that is, at a lower position due to its own weight. Following the upper and lower positions of the memory needle 3, the press bar 6 also assumes two positions; in the upper position, it is inactive, and in the lower position, it is in the operating position, and the press bar head 6a is in the sliding frame. It is operated by being pressed by a press grid 8 fixed to a press bar 7, and a punch 9 fixed to the tip of the press bar punches a hole in a pattern paper 11 attached between card wheels 10, which intermittently transfers the set pitch. It's summery.

The control of the upper and lower positions is also performed by the control plate 2, which controls the spring 1.
2, the regulating plate 14 integrally fixed with the plate 2 comes into contact with the flat surface 13a of the stop bar 13 to define the upper position, and is fixed to the swinging lever 16 that swings about the support shaft 15. The entire control plate 2 is pushed down to the lower position against the spring 12 by the vertical movement of the reset shaft 17.
Furthermore, solenoids 18 installed above the control plate 2 are provided corresponding to the respective control plates 2, and when the solenoids 18 are turned on, the protruding rods 19 engage the locking plates 20 fixed to the control plates 2, respectively. A lower position is selectively defined in each case by pressing. That is, when the reset shaft is lowered and all control plates 2 are in the lower position, turning on a designated solenoid 18 sets only the plate corresponding to the solenoid 18 in the lower position, and as the reset shaft 17 rises, the remaining control plates 2 are set in the lower position. control plate 2 is returned to the upper position by spring 12. By the operation of the control plate 2, the memory needle 3, which is hooked to the control plate and hangs down, also follows and selectively assumes the upper and lower positions,
The press bar 6 supported by the memory needle 3 assumes the vertical position, and by reciprocating the sliding frame 7, the press bar 6 located in the lower position is pressed against the press grid 8, and the punch 9 at the tip is pressed against the die 2.
The pattern paper 11 on top of 1 will be perforated.

Therefore, in such a paper punching machine, solenoid 1
The punch 9 is controlled by the ON signal given to the punch 8 to punch holes in the patterned paper, and by controlling the electrical signals, the desired punches can be made in the patterned paper.

As described above, the pattern paper PC of design P2 in Figure 2 is created. At this time, if the pattern paper of design P1 is set to A shown in Figure 4, the pattern paper PC of design P2 is created. The pattern paper is perforated like this.

That is, to summarize the present invention, a first master tape inputs the tape signal of the perforated tape t, which records the information of one weft L of the design drawing P1, into the microcomputer MCOP, and reads the partial design P-1a to be repeatedly woven. MT1 and partial design P-1
By inputting the two types of command information recorded on the second master tape MT2 that commands repeat punching of a on the pattern paper, the microcomputer MCOP performs arithmetic processing, and the part from L to one weft of the design drawing P1 is processed by the microcomputer MCOP. Converting the layout to information for one weft thread (L/2) of design P-1a, and further outputting the converted information as perforation information for repeatedly perforating the pattern paper to operate the paper perforation machine PM, It is made by perforating the patterned paper. Note that the partial design P-1a in the above example was 1/2 of the original design drawing P1;
Partial designs within a narrower range such as 3, 1/4... may also be suitable.

As described above, in the present invention, when a design is selected from among existing design drawings and the selected design is desired to be repeatedly woven, it is not necessary to create a new selected pattern, and the selected pattern is selected from among existing design drawings. By using a perforation tape, you can select only the perforation information of the pattern you want to weave from the perforation tape and repeatedly perforate the patterned paper.
The time required to create a pattern paper can be further shortened, and the cost of creating a pattern paper can therefore be reduced.
