Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing device such as a pocket setter having a folding part, a sewing part and a carrying part,
And a method for correcting the position of the cloth carrier to be sewn.

[0002]

2. Description of the Related Art For example, as one type of sewing device, there is a pocket setter for sewing a pocket on a body of a Y-shirt. The pocket setter conveys a work portion between two folding stations and a sewing portion. After moving the body and positioning the pocket cloth, which is the cloth to be sewn along the template along the template at the folding part, on the body set there, it was attached to the moving body. It is configured to be held by a presser plate, moved from the folding portion to the sewing portion, and sewn by the sewing machine head while feeding according to the shape of the pocket.

Therefore, in this type of sewing device, the positional relationship between the folding portion and the sewing portion and the carrier is an important factor that influences the quality of sewing. However, in an actually assembled device, this positional relationship may deviate from the designed positional relationship due to processing errors in the members of each part and variations during assembly. Is attached to the drive unit of the transport device through a long hole so that the transport member can be finely adjusted.

[0004]

However, the work of adjusting the position of the carrier by such a long hole is troublesome and time-consuming. In addition, for one work station, even if the position can be adjusted so that the reference point of the carrier coincides with the reference point, the position cannot be adjusted for the reference point of the other work station. In order to enable position adjustment between the work station and the carrier, for example, the template of the folding part, which is one of the work stations, must be position-adjustable to the mounting part by means of a long hole for fine adjustment. However, it took more and more work time, and accurate alignment was difficult.

Some automatic sewing machines have a function of correcting the deviation between the XY origin of the cloth feeding member driven by the XY mechanism and the needle drop point of the sewing machine. Even if it is used for, the origin of the carrier cannot be adjusted with respect to the two reference points, and fine adjustment by the long hole is still necessary.

Further, in the case of, for example, a pocket setter, a large number of pocket shapes to be sewn are produced in accordance with various designs and sizes. Therefore, the folding gauge of the folding portion and the template and the pressing plate of the conveying section (shape of the template) The slits having a shape corresponding to (1) are formed so that they can be easily attached to and detached from the main body so that they can be easily replaced with those having a shape corresponding to the pocket shape. Therefore, the template and the pressing plate are joined to the main body side by the replacement chuck, but the assembly from the chuck is specific to each template and the pressing plate.

Therefore, even if the misalignment in the assembling between the reference position of the transfer body or the pressing plate of the transfer section and the reference position of each work station of the folding section and the sewing section is corrected and the origin is adjusted, If the mold plate and presser plate are replaced with each other, there will be a deviation from each reference position that has been adjusted due to differences in their shapes and assembling errors, etc.If you continue sewing, the needle entry point of the sewing machine There is also a problem that the quality of the sewn product is significantly deteriorated due to the deviation.

The present invention has been made in view of the above-mentioned points, and the position of a carrier moving between a plurality of work stations in a sewing machine can be easily displaced with respect to each work station in a short time. To enable accurate positioning movement, and even after exchanging the template and the pressing plate, if the positional deviation peculiar to the combination is corrected once, then the same combination of the template and pressing plate can be obtained. When sewing with, the purpose is to be able to immediately sew to the correct position without having to readjust.

[0009]

In order to achieve the above-mentioned object, the present invention has a folding portion for selectively mounting a plurality of template plates having different shapes and folding a cloth to be sewn along the template plates.
A sewing portion for sewing with a sewing machine and a holding plate having a slit having a shape corresponding to the shape of the template are selectively attached to the carrier, and the cloth to be sewn in at the folding portion is pressed by the holding plate. The carriage is held and conveyed to the sewing section, and the conveyor is moved so that the needle drop point moves along the slit in the slit of the pressing plate during sewing by the sewing machine.
A sewing device including a transporting unit that is moved in two orthogonal directions by a -Y mechanism is provided with each of the following means (A) to (E).

(A) The correction value of the deviation amount between the reference position of the transfer body or the pressing plate of the transfer section and the reference position of each work station of the folding section and the sewing section is set in the X-axis direction of the XY mechanism and in the X-Y direction. First input as movement amount in Y-axis direction
Correction value input means, (B) first correction value storage means for storing each correction value input by the means, and (C) a deviation amount with respect to each reference position for each combination of the template and the pressing plate. Second correction value input means for inputting a correction value as the amount of movement of the XY mechanism in the X-axis direction and the Y-axis direction,
(D) Second correction value storage means for storing each correction value input by the means in sewing pattern data corresponding to each combination of the mold plate and the pressing plate, (E) the first and second Means for driving and controlling the XY mechanism so as to accurately move the carrier to each work station based on each correction value stored in the storage means,

According to the method for correcting the position of a cloth carrier to be sewn according to the present invention, in the above sewing apparatus, a reference template is attached to the folding portion and a reference holding plate is attached to the conveyor of the conveyor. Then, the correction values of the deviation amount between the reference position of the pressing plate and the reference positions of the work stations of the folding portion and the sewing portion are input as the movement amounts in the X-axis direction and the Y-axis direction of the XY mechanism, respectively. The drive data of the XY mechanism when the carrier is moved to each of the work stations is corrected based on the respective correction values, and thereafter, the fold mechanism and the carrier of the transport unit are respectively different. When the mold plate and the press plate are attached, the correction values of the deviation amounts with respect to the reference positions by the combination of the mold plate and the press plate are input as the movement amounts of the XY mechanism in the X-axis direction and the Y-axis direction, respectively. hand It is stored in the sewing pattern data corresponding to each combination of the template and the press plate, and in the subsequent sewing with the sewing pattern data, the drive data of the XY mechanism is further added by each correction value in the sewing pattern data. It is characterized by correction.

[0012]

According to the sewing apparatus and the method for correcting the position of the cloth carrier to be sewn according to the present invention, the correction value of the deviation amount between the reference position of the carrier and the reference position of each work station of the folding portion and the sewing portion is previously set. Are input as the movement amounts of the XY mechanism in the X-axis direction and the Y-axis direction, respectively, and are stored,
Thereafter, the drive data of the XY mechanism when moving the carrier to each work station is corrected based on the stored correction values, and the carrier accurately moves to each work station to sew the cloth to be sewn. Is always positioned and conveyed without deviation.

After that, when another template and a pressing plate are respectively attached to the conveying bodies of the folding section and the conveying section, the correction value of the deviation amount with respect to each of the above-mentioned reference positions by the combination of the template and the pressing plate is set to the above X value. -If the amount of movement of the Y mechanism in the X-axis direction and the Y-axis direction is input and stored in the sewing pattern data corresponding to each combination of the template and the presser plate, the sewing pattern data will be used thereafter for sewing. , The drive data of the XY mechanism is further corrected by the respective correction values in the sewing pattern data, so that readjustment is performed when sewing is performed with the same combination of the folding gauge, template, presser plate and sewing pattern data. You can immediately sew to the correct position without the need.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a schematic plan view of a pocket setter which is an embodiment of a sewing device according to the present invention, and FIG. 2 is a schematic perspective view including peripheral devices thereof. As shown in FIG. 1, the pocket setter includes a folding portion 1 and a sewing portion 2 which are work stations, and a conveying portion 3 which conveys a pocket cloth (not shown) which is a cloth to be sewn therebetween, on a table 4. It is located in.

The folding part 1 is formed, for example, by attaching a pocket-shaped template 5 of a Y-shirt to the main body 6 by a one-touch chuck 7 for exchanging the mold, and excluding the periphery of the set pocket cloth except the already sewn upper side. Fold it inside. Therefore, a folding device (gauge) 8 corresponding to the template 5 is also mounted as shown in FIG. Sewing machine 2 has sewing head 9
Is installed. The transport unit 3 is provided with a transport body 11 which is moved in the X-axis direction and the Y-axis direction by an XY mechanism (table) 10, and a pressing plate 13 is one-touched by a plate exchange chuck 12 at the tip of the transport body 11. Install with.

Then, the presser plate 13 is moved in the X-axis direction from the position where the pressing plate 13 overlaps the template 5 of the folding part 1, and the body and the pocket cloth which are previously positioned and overlapped by the folding part 1 are sewn in the sewing part 2. Transport to the sewing position by the head 9,
The carrier 11 and the pressing plate 13 are moved in the X-axis direction and the Y-axis direction by the XY mechanism 10 so that the needle drop point moves in the slit 13a formed in the pressing plate 13 along the slit. However, sewing is performed by the sewing machine head 9.

In addition to these parts, as shown in FIG. 2, the operation panel 14, the pocket cloth holder 15, the body holder 1
6, stacker 17, thread stand 18, switch box 19
Etc. are provided. Further, in the example shown in FIG. 1, since the corner bottom pocket is sewn, the corner bottom template 5 is formed on the main body 6 of the folding part 1 and the corner U corresponding to the shape of the template 5 is formed on the carrier 11 of the carrier part 3. Although the pressing plate 13 having the character-shaped slit is attached, if you want to sew a round bottom pocket,
These are a round bottom template 5'as shown in FIG. 3A and a round U-shaped template 5'as shown in FIG. 3B.
It is sufficient to replace the holding plate 13 'with the slit 13a' (corresponding to the shape of the above) and the folding device 8 accordingly.

In addition, a combination of a template and a folding device and a holding plate can be prepared according to pockets of various designs and sizes, and these can be used by appropriately exchanging them. In that case, sewing pattern data for controlling the relative movement of the needle drop point of the sewing machine head 9 and the presser plate at the time of sewing is also created in advance corresponding to the combination and stored in a memory, a floppy disk or the like. The sewing pattern data is also selected and used according to the replacement of the template or the like.

Here, the template 5 and the pressing plate 13 shown in FIG.
Are used as the reference template and the presser plate, respectively, and the coordinates of the design reference point of each part when these are mounted are shown in FIG.
Pa (x, y), sewing part 2: Pb (xm, ym), folding part 1: Pc (xk, yk). Further, the origin of the transport section 3 is the reference point Pb coordinates (xm, ym) of the sewing section 2, and the origin (0, 0) of all the coordinates. At this time, y = ym =
yk = 0. When the pressing plate 13 of the transport unit 3 moves at the coordinates of the folding unit 1, y = yk-ym = yk
Is.

In order to make a distinction for comparison, the coordinates of the origin (reference point Pa) of the transport section 3 are (x0, y0). here,
In the actually assembled device, the coordinates are misaligned due to processing errors, variations during assembly, and the like. Considering this deviation with respect to the coordinates of the respective reference points in the design, the coordinates of the origin Pa of the transport unit 3 are (x0 + Δx0,
y0 + Δy0), the coordinates of the reference point Pb of the sewing portion 2 are (xm +
Δxm, ym + Δym), and the coordinates of the reference point Pc of the folded portion are (xk + Δxk, yk + Δyk).

At this time, since the origin of all coordinates is the origin (x0 + Δx0, y0 + Δy0) of the transporting section 3, this is (x0, y0) when considered from the viewpoint of control, and the other coordinate reference is sewing. Part 2 is (xm + Δxm−Δx0, ym + Δym−
Δy0), and the folded portion 1 is (xk + Δxk−Δx0, yk +
Δyk−Δy0). Here, in consideration of control coordinates, a deviation of (Δxm-Δx0, Δym-Δy0) occurs in the sewing portion 2 and a deviation of (Δxk-Δx0, Δyk-Δy0) occurs in the folding portion 1.

Originally, the holding plate 13 that moves integrally with the carrier 11 of the carrier unit 3 is coordinate-managed by numerical values and X.
-It is moved by the Y mechanism 10. Therefore, the folding part 1
And the deviation amount between the reference points Pc and Pb of the sewing portion 2
By giving a numerical value to the control unit of the Y mechanism 8, it becomes possible to perform processing for correcting the amount of deviation.

As a method of inputting this deviation amount to the control unit, from a simple method of setting a value on a DIP switch and reading it into a computer of the control unit, each part is photographed by a CCD camera to perform image processing, You can think of an advanced method that automatically feeds back the amount of deviation,
A control unit having a correction value input means and a storage means in this embodiment will be described with reference to FIG.

As shown in FIG. 4, the control unit 20 of the sewing machine integrally controls the entire machine by a microcomputer including a CPU 21 which is a central processing unit, a ROM 22 which is a program memory and a RAM 23 which is a data memory. There is.

Reference numeral 24 is a bus for exchanging data and addresses with the CPU 21, and includes the ROM 22 and R described above.
In addition to the AM 23, an EE-PROM 25 for storing data of correction values described later, a floppy disk controller (FDC) 26 for controlling a floppy disk drive device (FDD) 27 which is an external storage device, a host computer, etc. RS-232C interface 28 for connection, folding device 8 and stacker 1 shown in FIG.
Peripheral interfaces 29 and 30 for inputting and outputting data to and from peripheral devices such as 7, an LCD controller 31, a keyboard interface 32, and a triaxial servo controller 33 are connected.

The LCD controller 31 includes a liquid crystal display (LCD) 34 capable of displaying characters, a CG-ROM 35 storing the character data thereof, and a V-map which is a bit map memory for expanding a character string displayed on the LCD 34.
-A RAM 36 is connected and displays guidance characters for inputting correction values, which will be described later, and a matrix frame with broken lines on the screen of the LCD 34 (see FIGS. 5 to 7).

A touch panel 37 forming a key matrix is connected to the keyboard interface 32, and the touch panel 37 is arranged on the screen of the LCD 34 on the operation panel 14 shown in FIG. 2 so as to be corrected. Enter the value. 3-axis servo controller 33
Drives the servomotors 41 to 43 via the servo drivers 38 to 40, respectively. The servo motor 41 is shown in FIG.
Servo motors 42, 4 for vertical movement of the holding plate 13 shown in FIG.
Reference numerals 3 are motors for driving the X-Y mechanism 10 for the X-axis and the Y-axis.

Next, a method of inputting a correction value for correcting the position of the transport unit according to this embodiment will be described with reference to FIGS. In the initial state after powering on the sewing machine, the CPU 21 causes the LCD controller 31 to
The LCD 34 of the operation panel 14 displays a "mode change" screen as shown in FIG. The layout of the key matrix is also displayed on this screen by broken lines, and the touch panel 37 constitutes a 16 × 8 key matrix correspondingly.

When the position "1" is touched,
The "XY origin adjustment" mode (a mode for matching the reference points of the sewing section 2 and the transport section 3) is selected, and the CPU 21
Causes the LCD controller 31 to display an “XY origin adjustment” screen as shown in FIG. 6 on the LCD 34.

There is a display of "z" at the positions 5-3 and 5-5 of the key matrix shown in FIG. 6, and when this is touched, the CPU 21 causes the 3-axis servo controller 33 to drive the servo motors 42 and 43. , The transfer unit 3 shown in FIG.
The holding plate 13 of is moved to the reference point of the sewing portion 2 (initially, a design reference point). Then, each servo motor 42, 43
Stops at the Z phase (reference point) and displays "00" at the positions 10-3 and 11-3 and 10-5 and 11-5 of the key matrix.

At this time, the reference point P of the holding plate 13 shown in FIG.
If "a" exactly coincides with the reference point (needle drop point) Pb of the sewing machine head 9, it means that there is no deviation. However, if it does not coincide, if it does not coincide, 13 of the key matrix Since "+" is respectively displayed on the LCD 24 corresponding to the positions of -3 and 13-5, each time the user presses any one of them, "0" of the corresponding X-axis or Y-axis is displayed.
The display of "0" is counted up and "01", "0
It changes like 2 ”and“ 03 ”. At the same time, CP
U21 turns the 3-axis servo controller 33 into the servo motor 4
2 or 43 by rotating the presser plate 13 forward at a predetermined pitch.
Move in the positive direction of the axis or Y axis by 0.1 mm.

Similarly, the key matrices 15-3, 15
Each time one of the "-" displayed on the LCD 34 corresponding to the -5 position is pressed once, the corresponding "00" display is counted down to "-0".
1 "," -02 "," -03 ", and at the same time, the CPU 21 causes the three-axis servo controller 33 to reversely rotate the servomotor 42 or 43 at a predetermined pitch to move the holding plate 13 to the X-axis or Y-axis. Move it by 0.1 mm in the negative direction of the axis.

In this way, the reference point Pa of the pressing plate 13 is
Is accurately matched with the reference point Pb of the sewing machine head 9 (visually confirmed), and then "registration" of the key matrix of FIG. 6 is performed.
When the position indicated by is touched, each correction value input as described above and temporarily stored in the RAM 23 (value corresponding to the numerical value displayed in the key matrix)
However, it is written and registered in the EE-PROPM 25 which is a non-volatile memory, and the data is not erased even when the power is turned off.

After that, the screen display of the LCD 24 returns to the state shown in FIG. 5, so when the position "2" is touched next, the "folding position adjustment" mode (to make the reference points of the folding section 2 and the transport section 3 coincide with each other). Mode) is selected, and the CPU 21 causes the LCD controller 31 to display a “folding position adjustment” screen on the LCD 34 as shown in FIG. 7. Then, the servomotors 42 and 43 are driven to move the holding plate 13 of the transport unit 3 in FIG. 1 to the folding unit 1, and the reference point Pa of the holding plate 13 is made to coincide with the reference point Pc of the template 5. And

However, since there is no coincidence if there is a positional deviation, as in the case described above, each position in the key matrix of the touch panel 37 where "+" or "-" is displayed is touched, and the pressing plate 13 is touched. After making the reference point Pa of (1) coincide with the reference point Pc of the template 5 (by visually confirming), if the position of registration is touched, "00" was initially displayed for each of the X axis and the Y axis. The correction value data corresponding to the numerical value displayed at the position is written and registered in the EE-PROM 25.

In this way, when the position correction data for the sewing section 2 and the folding section 1 are stored in the EE-PROM 25, the CPU 21 causes the XY mechanism 1 of the transport section 3 thereafter.
When controlling 0, the correction data is referred to and the presser plate 13
Is controlled so as to accurately move from the reference position of the folding portion 1 to the reference position of the sewing portion 2. FIG. 8 shows the origin of design and the reference points Pa and P of the respective parts in the actual device.
The relationship between b and Pc on the x and y coordinates is shown.

By performing the origin adjustment and the folding position adjustment in this manner, as long as the reference template 5 and the folding device 8 and the presser plate 13 are mounted, the sewing pattern data corresponding to the combination can be obtained by the FDD 27. By reading out from the floppy disk, storing it in the RAM 23, and controlling the XY mechanism 10 according to the data, the pressing plate 1
3 can be accurately moved with respect to each work station of the folding part 1 and the sewing part 2 and the needle drop point, and high-quality sewing can be performed.

However, as described above, it is necessary to replace the template, the folding device, and the holding plate according to the design and size of the pocket to be sewn. Therefore, as described above, the carrier 11 of the carrier unit 3 or Base plate 1
Even if the reference position of 3 and the reference position of each work station of the folding part 1 and the sewing part 2 are corrected to adjust the origin and then the template and the presser plate are replaced, A deviation with respect to each reference position adjusted due to a difference in shape and an assembly error will occur.

Therefore, for each combination of the template, the folding device, and the holding plate, when they are first mounted and used, the correction value of the deviation amount is used as the X-axis direction and the Y-axis direction of the XY mechanism 10. Is input as a movement amount of, and it is stored in the sewing pattern data corresponding to this combination. In this embodiment, the LCD 3 of the operation panel 14 is in the initial state.
When the "mode change" mode of "3" is selected when the "mode change" screen shown in FIG.
At "D34", the "mold correction (presser plate)" screen shown in FIG. 9 is displayed.

At this time, the CPU 21 causes the three-axis servo controller 33 to drive the servomotors 42 and 43, and the reference point Pa of the holding plate (for example, 13 ') of the conveying section 3 shown in FIG.
To move to the reference point Pb of the sewing portion 2. Then, the servo motors 42 and 43 are stopped at the Z phase (reference point), and the values of "0" are set at the positions 10-3 and 11-3 and 10-5 and 11-5 of the key matrix.
"0" is displayed.

Therefore, it is confirmed whether or not the two reference points Pa and Pb are coincident with each other. If they are not coincident with each other, the X-axis and the X-axis on the key matrix are adjusted as in the case of the XY origin adjustment on the screen of FIG. Press the position where "+" is displayed or the position where "-" is displayed for the Y-axis, and the XY mechanism 10 moves the presser plate in the positive or negative direction of the X-axis and the Y-axis by one pitch (0. 1 mm) to make both reference points Pa and Pb coincide with each other. As a result, the numerical value "00" displayed for the X axis and the Y axis increases or decreases.

After confirming the coincidence of both reference points, if the position indicated as "registration" on the key matrix is touched, the correction values (keys entered as described above and temporarily stored in the RAM 23 are stored. The value corresponding to the numerical value displayed in the matrix) is written in the corresponding sewing pattern data. Then, the screen of the LCD 34 is changed to "mold correction (mold plate)" shown in FIG. 10, the pressing plate is moved to the work station of the folding section 1 by the XY mechanism, and the mold having the reference point Pa attached thereto is mounted. An attempt is made to move the plate (for example, 5 ') to the reference point Pc.

Therefore, it is confirmed whether or not the two reference points Pa and Pc are coincident with each other, and if they are not coincident with each other, the both reference points Pa and Pc are made to coincide with each other in the same manner as described above, and then on the key matrix. Touch the position where "Register" is displayed. As a result, the correction values (values corresponding to the numerical values displayed on the key matrix) that have been input and temporarily stored in the RAM 23 are written in the corresponding sewing pattern data, and the sewing pattern data is stored in the nonvolatile memory. It is written and registered in EE-PROPM25 which is
Even if the power is turned off, the data will not be erased.
Alternatively, the FDD 27 may be written on the floppy disk and stored.

In this way, the correction amount peculiar to each reference position is input as the movement amount in the X-axis direction and the Y-axis direction of the XY mechanism for each combination of the various mold plates, the folding device and the holding plate. Then, if it is stored in the corresponding sewing pattern data, each sewing machine has its own correction value in the sewing pattern data. Therefore, when the same combination of templates and the like is subsequently mounted and used, the movement amount of the moving body 11 by the XY mechanism can be corrected by the correction value in the sewing pattern data, and readjustment is required. It is possible to perform sewing at an accurate position without needing to do so.

Further, if the above-mentioned XY origin adjustment and folding position adjustment are performed by the same template and presser plate as a reference for each sewing machine, each template and folding device and the presser plate and sewing pattern data can be stored. The combination type is
It is compatible with not only one sewing device but also another sewing device.

In this embodiment, the CPU shown in FIG. 4 is used.
11, the LCD controller 31, the LCD, the keyboard interface 32, the touch panel (key matrix) 37, etc., and the RAM for the first and second correction value input means.
23, the EE-PROM 25, the FDD 27, etc., constitute first and second correction value storage means, and the CPU 11, the 3-axis servo controller 33, etc., constitute means for controlling the XY mechanism.

Although the embodiment in which the present invention is applied to the pocket setter has been described above, the present invention is not limited to this, and a plurality of mold plates having different shapes are selectively mounted, and the mold plates are arranged along the mold plates. A folding part that folds the cloth to be sewn,
A sewing part for sewing with a sewing machine and a holding plate with a slit having a shape corresponding to the shape of the template are selectively attached to the carrier, and the work cloth folded at the folding part is held by the holding plate. And the transport unit that moves the transport body in two orthogonal directions by the XY mechanism so that the needle drop point moves along the slit in the presser plate during sewing by the sewing machine. The same sewing machine can be applied to all the sewing machines.

[0048]

According to the present invention, the position correction data of the carrier for mounting the holding plate, which is moved by the XY mechanism between the work stations of the folding part and the sewing part in the sewing machine, is input and stored in advance. After that, the driving data of the carrier is corrected after that, and the holding plate accurately moves to each work station to position and convey the cloth to be sewn without deviation. Therefore, the position of the carrier with respect to each work station can be easily adjusted in a short time, and the processing and assembling errors can be absorbed, so that the processing accuracy can be lowered and the design efficiency and the cost can be reduced. Moreover, the quality of the sewn product can be improved.

Further, even if the template and the presser plate are exchanged, once the positional deviation peculiar to the combination is corrected and the correction value is stored in the sewing pattern data, the same template is thereafter obtained. When sewing with a combination of the presser plate and the presser plate, it is possible to immediately sew to an accurate position without the need for readjustment.

A sewing portion for sewing with a sewing machine and a holding plate having a slit having a shape corresponding to the shape of the template are selectively attached to the carrier, and the cloth to be sewn at the folding portion is pressed by the holding plate. The carrier is held and conveyed to the sewing section, and when the needle is sewn by the sewing machine, the conveyer is moved along the slit so that the needle drop point moves along the slit.
In a sewing device including a transport unit that is moved in two directions orthogonal to each other by a Y mechanism, a reference template is attached to the folding section, and a reference retainer plate is attached to the conveyor of the transport section. The correction values of the deviation amount between the reference position of the plate and the reference positions of the work stations of the folding portion and the sewing portion are input and stored as the movement amounts of the XY mechanism in the X-axis direction and the Y-axis direction, respectively. Based on the respective correction values, the drive data of the XY mechanism when the carrier is moved to the respective work stations is corrected, and thereafter, another template is provided on the carrier of the folding section and the carrier. When the press plate is attached, the correction value of the amount of deviation with respect to each of the reference positions due to the combination of the template and the press plate is input as the amount of movement of the XY mechanism in the X-axis direction and the Y-axis direction, respectively. Then, it is stored in the sewing pattern data corresponding to each combination of the template and the press plate, and at the time of subsequent sewing with the sewing pattern data, the drive data of the XY mechanism is adjusted by each correction value in the sewing pattern data. A method for correcting the position of a sewn cloth carrier, further comprising:
