DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to automatic linking system to create operating data for driving the knitted fabric sewing device.

[0002]

2. Description of the Related Art The sewing operation of a knitted fabric such as a sweater is characterized by the fact that the knitted fabric to be worked is flexible and the degree of elongation changes and the dimensions change depending on how the force is applied. In fact, they actually have to work with a sewing machine or jig.

[0003] In particular, in a linking operation in which the stitches of two knitted fabrics to be stitched together are overlocked, the stitch is set to one stitch.
Since it is necessary to adjust each eye, automation is very difficult, and it is usual to work manually using a linking sewing machine as follows. In other words, a person pierces one knitted fabric with a fixed point needle while picking up the eyes one by one, furthermore, aligns the eyes from above and pierces the knitted fabric to be sewn, and moves the part where the needle piercing is over to the sewing machine part. Then, sewing is performed using the point needle as a guide to perform linking.

[0004] The present applicant has proposed a sewing apparatus which enables automatic linking work (Japanese Patent Publication No. 3-49477).

[0005]

However, in the sewing apparatus according to this proposal, the number of stitches of the knitted fabric to be stitched is not completely the same as in the case of attaching sleeves to a knitted sweater, and the length of the knitted fabric is not exactly the same. At the time of suturing a portion where it is important to match the stitches, it is necessary to pick up all the needles one by one on one side of the knitted fabric and pierce one stitch on the one side of the knitted fabric. In that case, based on the sweater design information, it is necessary to partially change the control logic at the time of needle puncture by inputting the condition of starting the second eye from the beginning into the microcomputer at the start. there were. For this purpose, the user manually inputs the input operation of the microcomputer or the instruction of the change content of the control logic from the keyboard. For this reason, there is still room for improvement in the fully automatic linking operation. An object of the present invention, in view of the above, can be automatically linking that automatically create operating data for driving the automatic sewing device to simplify the operation of the user related to the automatic linking operation It is to provide a system.

Embodiments of the present invention will be described below in detail with reference to the drawings.

Basic Principle In this embodiment, automatic stitching of knitted fabrics having different numbers of stitches is enabled by providing stitches (skip skipping) for which the number of stitches in two knitted fabrics is large. There is a feature.

A basic processing method for this will be described below.

In the case where the p-th (integer) stitch of the first knitted fabric and the q (integer) stitch of the second knitted fabric are sewn as indicated by circle signals in FIG. The remaining number is r = pq
Becomes Therefore, in this embodiment, the skipped portions are sorted to the central part of the number of stitches of the entire sewn part at a fixed distance to the left and right from the center point. More specifically, for a knitted fabric having a large number of stitches, the number of skipped positions is determined as much as possible, such as sewing → skipping → sewing from a position at a fixed distance from the center point. In a knitted fabric having a small number of stitches, all stitches in a sewn portion are to be sewn.

FIG. 2 shows the knitted fabric used in the example and the shapes after sewing.

In FIG. 2, a portion indicated by reference numeral A indicates a shape after sewing, and a portion indicated by reference numeral B indicates each knitted fabric shape and its design position.

As shown in FIG. 2, the number of eyes (C) of the predecessor part =
256 Number of eyes in the back part (AI + K × 2) = 88 + 95 × 2 = 27
In order to be 8, it is necessary to make a skip in the back part. Since skipping is not allowed in the side eyes (C of the front part: AI of the back part), it is put in the vertical eyes (K of the back part). The number of times of skipping is as follows: Number of times of skipping = (AI + K × 2) −C = 278−256 = 22, and it is necessary to insert the eleventh skip in the K (95) th eye.

From the above, the vertical line K is as shown by the symbol C in FIG.

FIG. 3 shows the correspondence between the back body and the front body of the stitch to be sewn.

In this way, if only the number of stitches of each knitted fabric is known, the skipping position can be calculated according to predetermined conditions.

An automatic linking system implementing such an algorithm will be described. FIG. 4 shows a system configuration of the automatic linking system.

(6) Process end: This is a process for ending the system process, which is realized by an instruction from the keyboard 103.

Hereinafter, the operation of the present system will be described with an example of a user operation for operating the automatic sewing apparatus 200.

(I) Input of Design Data When the user inputs design data from the keyboard 103, “1. Data input” is displayed on the menu screen of FIG.
Is selected (step S20 in FIG. 8). The selected content is identified in step S30 of FIG. 8, and the execution procedure of the CPU 101 shifts to the data input process of step S100. FIG. 9 shows a detailed procedure of this processing.

The CPU 101 displays a data input processing menu screen as shown in FIG.
Wait for input from 03. In this embodiment, three types of data can be input from the keyboard 103: a) design data, b) mechanical origin data, and c) image processing parameters.

The design data is data indicating the design and structure of the knitted fabric on which the operation data is based.

The mechanical origin data is stored in the C of the automatic sewing apparatus 200.
This data indicates the needle origin position and the hand origin position of the measurement target of the CD 55. If there is no data input for the mechanical origin data, a predetermined initial value (default value) is used.

The image processing parameters are determined by the CCD 55,
Data used for image processing for inspecting the stitch imaged by 55 '. If there is no input of this data, a default value is also selected.

The user selects “1. Design data input” on the display screen of FIG.
As a result, the CPU 101 switches the display screen to the design data input screen (step S101 → S10 in FIG. 9).
2).

FIG. 17 shows a display example according to the present invention in the design data input screen. The user inputs the design of the knitted fabric (dimensions, colors, number of stitches) from the keyboard 103 in correspondence with the items described on this display screen (FIG. 9).
Step S103). For reference, FIG. 18 shows the relationship between the type of design data and the shape of the knitted fabric.

The CPU 101 temporarily stores the input design data in a work area in the system memory 102 in FIG. 5 (step S104 in FIG. 9).

Thereafter, when the user inputs an end instruction from the keyboard 103, the CPU 101 detects the end instruction in step S105 in FIG. 9 and ends the processing procedure in FIG. 9 (the processing in step S100 in FIG. 8). Then, the execution procedure returns to step S10 in FIG. As a result, the menu display screen of FIG. 15 is displayed again.

When inputting the design data written on the IC card 50B by the knitted fabric designing apparatus, the user
The C card 50B is mounted on the card reader / writer 105 (see FIG. 5), and “2.
"IC card access process" is selected. The IC card access screen of FIG. 19 is displayed by this selection.
The user selects “a) design data” of “1. The CPU 101 transmits these series of instructions in steps S10 to S40 in FIG. 8 → S200 → step S200 in FIG.
At 201 to S202, the design data is read from the IC card 50B and stored in the work area in the system memory 102.

When inputting the data stored in the floppy disk 50A, the user selects “3. File processing” in FIG. 15 and then “1. Read” in the file processing screen of FIG. select. At this time,
When the user inputs a file name from the keyboard 103, the CPU 101 reads the design data from the floppy disk 50A mounted on the FDD 104 and stores it in the work area in the system memory 102 (steps S20 to S50 in FIG. 8 → S300 → FIG. 11). S310 to S33
0 → S331 → S332).

As described above, when the design data is input and stored in the system memory 102, a conversion process to operation data is performed next.

(Ii) Creation of operation data The user selects “4. Data conversion processing” on the menu screen of FIG. 15 and changes the data conversion menu screen of FIG.
Display on PU 101 (Steps S20 to S6 in FIG. 8)
0 → S400 → S410 in FIG. 12).

The user selects “1.L” on the menu screen of FIG.
When “PT data conversion” is selected, the CPU 101 proceeds with the execution procedure of steps S410 → S420 → S425 → FIG. 13 in FIG. 12, and performs LPT data conversion in the processing procedure of FIG. The knitted fabric that needs to be skipped (the knitted fabric with a large number of stitches) is detected by comparing the magnitude relations (step S100 in FIG. 13).
0, S1010).

Thereafter, the CPU 101 determines the stitch position (needle position) for skipping and the stitch position (needle position) for sewing.
Is calculated according to a predetermined arithmetic expression, and is converted into operation data indicating a sewing operation (step S1015 or S1020 in FIG. 13).

On the other hand, when the numbers of the two stitches match,
It is not necessary to skip over the stitches, and the operation data is created in a one-to-one correspondence between the stitch positions and the sewing positions (steps S1000 to S1005 in FIG. 13).

Further, other operation data, for example, the transport amount of the knitted fabric and the like are calculated from the number of vertical stitches. The operation data relating to the linking of the knitted fabric is determined corresponding to the stitch arrangement. For this reason, in the present embodiment, an operation expression (including a logical operation expression and a conditional expression) for calculating the value of the operation data from the design data is determined in advance for each type of operation data. By executing, the operation data for the automatic sewing device 200 is created, and the system memory 10

0).

Thereafter, the user gives an instruction on the menu screen as necessary, and saves the operation data created, the mechanical origin data, and the image processing parameters in the IC card 100B or the floppy disk.

These processes are the reverse of the above-described process of reading the design data from the storage medium, and a detailed description thereof will be omitted in this embodiment. FIGS. 10 and 11 show the processes for reading the IC card and the floppy disk. Just write down the writing procedure.

(Iii) Linking Process The user transfers the operation data, mechanical origin data, and image processing parameters from the sewing pattern design device 100 to the automatic sewing device 200 online or offline.

The data received by the automatic sewing apparatus 200 is stored in the operation data memory 53 by the CPU 50 shown in FIG.

In the case of online transfer, data is input from the communication interface 51, and in the case of offline transfer, data is input from the FDD 57 or the card reader / writer 58.

When the user gives a driving instruction from the operation unit 59, the CPU 50 controls the linking mechanism 52 in accordance with the operation data in the operation data memory 53 to link (sewing) the knitted fabric.

On the other hand, the CPU 50 activates the timer 56 simultaneously with the start of the operation, and measures the operation time until the end of the operation.

The linking operation of the linking mechanism 52 is C
Monitored by CD55. The image data at the position indicated by the image parameter from the imaging result of the CCD 55 is CP.
The image is sampled by U50 and subjected to image correction processing instructed by other image parameters. Based on the image data thus obtained, the stitch position is detected,
It is used for minute movement control of the knitted fabric position.

A stitch position detection process executed by the CPU 50 will be briefly described.

The density of each pixel indicated by the imaging result is compared with a threshold value given by the image processing parameter to detect a pixel portion whose density is higher than the threshold value. This pixel portion is shown in FIG.
2 shows a stitch portion surrounded by a knitting yarn as indicated by a shaded portion.

The area of one stitch is calculated by counting, by the CPU 50, the number of pixels whose stitches indicate the stitch.

The normal / error of the stitch is determined by comparing the area of the stitch thus determined with the allowable range for the area also given by the image processing parameter by the CPU 50. In this case, when the area is within the allowable range, the normal determination is made.

Further, the CPU 50 counts the number of stitches for performing minute movement control (linking processing) of the stitch position, makes a comparison with an allowable value given by the image parameter or the operation data, and determines whether the number is normal. Is determined.

Further, in addition to the above-described error detection, the CPU 50 determines whether or not the distance between the centers of gravity of the stitches is normal. In the present embodiment, as shown in FIG. 23, it is determined from the detected stitch p whether or not the next row of stitches exists in a range surrounded by a hatched portion. When a stitch exists, the stitch distance is normal. In this way, the CPU 50 performs various inspections on the imaging result, and when an error occurs, creates an identification code (error code information) indicating the content of the error. If no error occurs, position coordinate information indicating the center of gravity position of each stitch is created as post-drive result information.

The operation result information includes, for example, the sewing time measured by the timer 56, the sewing site given from the operation data and the number of sewing sites. The error code information and the post-operation error information thus created are temporarily stored in the system memory 53.

FIG. 24 shows the processing procedure of the CPU 50 described above.

The thus obtained error code information and post-operation result information such as operation time are transferred to the sewing pattern design apparatus 100 via the communication interface 51 in the case of online connection. Sewing pattern design device 10
At 0, when the post-operation result information and the error code information are received via the communication interface 109, the received information is temporarily stored in the system memory 102 by the CPU 101.

In the case of off-line connection, post-operation information is written to a storage medium (IC card or floppy disk) mounted on the automatic sewing apparatus 200.

(IV) Screen display of post-operation result information and error code information In this embodiment, the operation state information and error code information are displayed on the display 106 of the sewing pattern design apparatus 100 to confirm the sewing state of the knitted fabric. be able to.

In this case, the user selects “5. Screen display” on the menu screen of FIG. When the post-operation result information and the error code information are input from the storage medium, the information is transferred to the system memory 102 using the access menu or the file processing menu of the IC card.

Since the menu screen shown in FIG. 25 is displayed by this menu selection, the user selects desired data (steps S20 to S70 → S500 → FIG. 1 in FIG. 8).
4).

When the CPU 101 identifies the content of the selected data, it reads out the data selected by the user from the data stored in the system memory 102 and displays it on the display screen (steps S510 → S5 in FIG. 13).
20 → S530).

On the other hand, when the creation of a graph is selected, a graph is created and displayed on the screen based on the data stored in the system memory 102 (step S51 in FIG. 13).
0 → S520 → S540). FIG. 26 shows an example in which the stitch center of gravity is graphically displayed.

Therefore, the user can know the stitch structure of the sewn knitted fabric and the presence or absence of an error by looking at this display.

(V) Creation of Image Processing Parameters In this embodiment, a threshold value (image processing parameter) used for determining an error of a knitted fabric is created from input knitted fabric design data in order to sew knitted fabrics of various shapes. can do.

For example, the number of stitches corresponds to the number of stitches in the design data, and the stitch area can be calculated from the number of stitches and shape / dimension data. When the user selects “2. Parameter conversion” on the menu screen of FIG.
Extracts relevant data from the design data already stored in the system memory 102 and calculates various image processing parameters according to a predetermined arithmetic expression (steps S410 → S420 → S430 → S440 in FIG. 12).
After this calculation result is temporarily stored in the system memory 102,
The data is transferred to an IC card or a floppy disk according to a user's instruction.

As described above, in this embodiment, (1) When sewing two knitted fabrics having different numbers of stitches, a skipped portion is provided for a knitted fabric having a larger number of stitches. As a result, the stitches of the two knitted fabrics can be associated with each other on a one-to-one basis, so that two knitted fabrics having different numbers of stitches can be sewn.

(2) Since the operation data for the automatic sewing device is automatically created from the design data of the knitted fabric, the user does not need to create the operation data in advance and need to input a key, thereby reducing the user's labor for creating the operation data. Is done. Further, as the design data of the knitted fabric, the data used at the time of creating the operation data of the knitting machine can be inputted online or offline.

(3) In addition, since the image processing parameters used for the knitted fabric inspection are automatically created from the knitted fabric design data, there is no need for the user to individually input these image processing parameters.

(4) Since the user can see the result of the knitted fabric inspection in the form of a graph (graphic), the sewing state of the knitted fabric can be monitored remotely.

(5) Since the abnormality of the knitted fabric and the content thereof can be known from the result of the knitted fabric inspection, the automatic sewing device can be stopped in response to the abnormality detection.

In addition to this embodiment, the following examples can be given.

1) In this embodiment, the sewing pattern designing apparatus 100 and the automatic sewing apparatus 200 shown in FIG.
These devices may be integrated.

2) Needless to say, the knitted fabric designing device 40 and the sewing pattern designing device 100 may be integrated.

3) The skip positions set when sewing two knitted fabrics having different numbers of stitches may be arranged in a fixed arrangement irrespective of the shape of the knitted fabric. Can be changed in relation to For example, when the number of skipping times is large, the interval between the skipping positions is shortened. In this case, an array of the skip positions corresponding to the number of eyes and the number of skips or a parameter value indicating the array is stored in a system memory in a table form, and the corresponding number of stitches indicated by the design data is stored in a table form. CPU101

4) The conversion of the operation data and image processing parameters from the design data may be performed by using a conversion operation expression such as a numerical operation expression or a logical operation expression. Time is reduced.

5) The following processing can be performed for processing an error code generated on the automatic sewing apparatus 200 side.

A) The linking mechanism 52 is controlled by the CPU 50 in the automatic sewing apparatus 200 in response to the occurrence of an error code.
Stops operation and generates an alarm.

B) When displaying an error code in the sewing pattern design apparatus 100, not only the error code but also
Displays the error message as a message. In this case, the message is stored in the system memory 102 of the sewing pattern design apparatus 100 in association with the error code, and a message corresponding to the generated error code is retrieved and extracted from the system memory 102 by the CPU 101.

6) In this embodiment, an example is shown in which design data is directly converted into operation data. However, design data is once converted into intermediate data, and stored in a storage medium in the form of intermediate data. The intermediate data stored in the storage medium can be converted into a format of operation data. Here is an example. When sewing the knitted fabric shown in FIG. 2, information tables corresponding to the knitted fabric and the needle of the automatic sewing device 200 are shown in FIGS. 27 and 28 as intermediate data.

FIG. 27 shows the contents of the information table corresponding to the stitch. In FIG. 27, the address indicates the data storage position of the information table, and corresponds to the stitch position of the sewing part. The skip data and stitch type data are stored in the data storage position indicated by the address.

The data "0000" in the skipping section means that skipping is not performed. Data “1000” in the skipping section means that skipping is performed. Data “FFFF” of the skipping item indicates an end code, data “0100” of the stitch type item indicates a vertical stitch, and data “0010” of the stitch type item indicates a horizontal stitch.

If such intermediate linking data corresponding to a stitch is created, operation data for various automatic sewing apparatuses having different formats of operation data can be created from the linking data. In this case, it goes without saying that a conversion formula from the intermediate linking data to the operation data is determined for each of the formats, and this conversion formula is selected.

FIG. 28 shows the contents of the information table corresponding to the needle numbers on the automatic sewing machine side.

In FIG. 28, the addresses correspond to the needle position and the data storage position. "000" in the stored data
"0" means that one needle is stabbed by the first stitch.
"01" means that one needle is stabbed by the second eye.
000 "means that one needle is stabbed with one glance.
“1001” means that one needle is stabbed with the second glance. “FFFF” indicates a sewing end code.

The information table has the advantage that the operation data can be created by correcting the operation data of another created knitted fabric.

7) In this embodiment, the case where the number of stitches is different has been described. However, skipping can be performed even when the number of stitches is equal.

In FIG. 2, the number of eyes of the predecessor (N) = 5
5. Even when the number of sleeves is equal to 55 = 55, skipping can be performed. The needle pitch is HPmm, the stitch pitch is APmm, and the stitch elongation is SS. When AP × SS> HP as shown in FIG. 29, the skipped number M <N × (1−HP / (AP × SS). , N × (1−HP / (AP × SS)), and the linking speed can be improved.

In addition, when the number of stitches exceeds a predetermined number, a predetermined number of skipping positions can be provided according to a predetermined arrangement as shown in FIG.

[0142]

As described above, according to the present invention, not only automatic linking (sewing) can be performed on knitted fabrics having different numbers of stitches, but also operation data of the automatic sewing apparatus can be easily created, and linking can be easily performed. This has the effect of greatly reducing the user's operation labor involved in the processing.
