Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sewing device for forming a seam pattern on a processed cloth, and in particular, the present invention relates to a sewing device for forming a seam pattern on a processed cloth. The present invention relates to a sewing device capable of forming a stitch pattern.

[Prior Art] Conventionally, when a work cloth is fixed to a particular work cloth holder, such as a particular embroidery frame or pallet, and then fed to a sewing position, a predetermined stitch pattern corresponding to the pallet, etc. is created. Sewing devices that automatically form sewing patterns on work cloth are known. As such, for example, Special Publication No. 58-500745,
As described in Publication No. 58-500746 and No. 58-500747, an identification code is attached to the pallet, the identification code is detected, pattern data preset according to the identification code is read out, and the workpiece cloth is One that forms a stitch pattern on the top is known. Also, JP-A-61-100286
As described in the above publication, it is known that a plurality of pattern data are set in advance in a predetermined order, and work cloth fixed to a specific pallet corresponding to each pattern data is supplied in the setting order of the pattern data. . Also, JP-A-61-100286
In the invention described in the publication, each pallet is attached with an identification code corresponding to specific pattern data, and by detecting the identification code, it is determined whether or not the pallets are supplied in the order of the pattern data, This prevents the occurrence of defective products due to pallet supply errors.

[Problems to be Solved by the Invention] However, in the conventional apparatus described above, for example, when forming the same pattern at different magnifications, pattern data corresponding to each must be set in advance.
There was a problem in that creating pattern data required a great deal of effort. Another problem is that a large-capacity storage device is required to store pattern data for each type of pattern to be formed.

Furthermore, even if a large amount of pattern data can be stored, if you want to change the magnification of a certain pattern, you will have to create new pattern data corresponding to this, and it will take time to design a new pattern. There was a problem.

Therefore, the effort required to create pattern data can be reduced, patterns can be formed under various conditions, and large-capacity storage devices are not required.
The present invention has been made to provide a sewing device that can quickly and easily design new patterns.

Structure of the Invention [Means for Solving the Problem] The present invention, which has been made to solve the problem, includes a seam forming means M1 and a work cloth holder for holding a work cloth C, as illustrated in FIG. M2, and a driving means M3 for changing the relative positional relationship between the stitch forming means M1 and the work cloth holder M2.
and a control means M4 that controls the driving means M3 and the seam forming means M1 based on the reference pattern data to form a desired seam pattern on the work cloth C held by the work cloth holder M2.
an identification means M6 for identifying information M5 attached to the work cloth C or the work cloth holder M2;
and a modifying means M7 for modifying the reference pattern data according to the identified information M5! The gist is device A.

[Function] In the sewing apparatus of the present invention, information M5 regarding a desired pattern is attached to the jOeiffc or work cloth holder M2. Information M5 is information for modifying predetermined reference pattern data into a desired form, such as magnification, thread density, 1 interval, 2 rotation angles, 9 reversal instructions.

Among sewing machines equipped with array reference lines and a needle bar switching device, there are machines that directly display color selection, etc., and machines that select one of a plurality of preset correction processing information.

Note that the reference pattern data represents the reference form of a certain pattern, and may be stored in advance in the sewing device, or may be read from an external device at any time. Information M5
is identified by the identifying means M6 and sent to the modifying means M7.

The correction means M7 corrects the reference pattern data according to the information M5, and sends the corrected reference pattern data to the control means M4. The control means M4 drives and controls the drive means M3 and the stitch forming means M1 based on the sent reference pattern data. The stitch forming means M1 and the driving means M3, which are driven and controlled, form a stitch pattern on the work cloth C in a desired form.

That is, it is possible to form various types of stitch patterns by combining the reference pattern data and the information M5. Therefore, it is not necessary to create various pattern data according to the form of the stitch pattern, and by changing the information M5, it is possible to form stitch patterns of infinite forms based on certain standard pattern data.

At this time, the carriage 19 is at the loading position 2C. continue,
The electromagnet 22 is energized and the pallet 55 or 58 is held on the carriage 19. Next, in S3, the barcode reader 9 reads the barcode 56 or 59, and in S4, the modified data T11 or T42 represented by the barcode 56 or 59 is read.
is in the correction table. If the determination is affirmative, the process advances to S5 and the modified data T11 or T42 is read from the modified table. Subsequently, the reference pattern data is corrected in S6. For example, when the correction data T42 is specified by the barcode 59, the magnification d1=2.0 is determined in S5. The correction information of the arrangement angle d2=90' is read, and based on this, the reference pattern data is enlarged twice in S6 and the phase is converted so that the arrangement angle becomes 90'. Next, the process advances to S7, and based on the corrected reference pattern data, the sewing machine motor 13.
The XY step motors 20 and 21 are driven and controlled, and the shirt 5 is
A pattern 54 is formed on the left cuff 53a of No. 3. When the pattern 54 is formed, the XY step motors 20 and 21 are driven at 88, the carriage 19 is moved to the take-out position 2d, and the electromagnet 2
2 is de-energized to release the pallet 58, and at the same time drive the take-out step motor 28 to take out the pallet 58, the process advances to S9 and it is determined whether or not there is a next pallet. If the next pallet 55 is on the input position 11, S2 is returned again.
Return to This time, since the barcode 56 means the modified data Tll, the reference pattern data is left the same as that stored in the external storage device 42 in S6, and the pattern 52 is formed.

On the other hand, if the barcode instruction read in S3 is not found in the correction table, such as correction data Txy, a negative determination is made in S4, and the process proceeds to S10, where the display 50 displays the message PA unregistered. The operator inputs the magnification d1=corresponding to the correction data Txy from the keyboard 41.
The process of S10 is repeated until x and the arrangement angle d2=y° are input (S11). When d+ =Xe dz =y' is input, the process advances to 812 and new correction data TXV is added to the correction table stored in the external storage device 42.

After that, the processing from 84 onwards is executed.

Here, S5, 36 corresponds to the processing as the correction means M7, and S7 corresponds to the processing as the control means M4.
