In the sewing machine configured as described above, before the pocket setter 6 starts to operate, the support member 7 is arranged at the standby position where it is separated upward from the table 1, and in that state, the gauge plate 10 Is sunk under the support member 7, and the holding plate 13, the bent piece holding plate 16 and the clamp 35 are arranged at the upper position.

Therefore, when the front body W is placed on the work cloth supporting surface 1a below the clamp 35 and the body clamp switch 66 is operated, step S1 shown in FIG.
The determination result of (the same applies to other steps, hereinafter, simply S1) is YES, the setter side CPU 63 operates the air cylinders 41 and 42, and lowers the clamp 35 as shown in FIG. 12A. .. As a result, the front body W
Is pressed and held on the work cloth supporting surface 1a by the clamp 35 (S2).

Next, the setter side CPU 63 operates the TV camera 61 to photograph the pattern Wa of the front body W (S
3) The image data of the pattern Wa is stored in the RAM 65 (S4). Subsequently, the setter-side CPU 63 operates the air cylinder 8 to cause the gauge plate 10 to project above the front body W as shown in FIG. 12B (S5). Therefore,
After the pocket piece P is placed on the gauge plate 10, the pocket piece clamp switch 67 is operated (S6.YE
S), the setter side CPU 63 lowers the pressing plate 13 and the bent piece holding plate 16 respectively as shown by the two-dot chain line in FIG. 4, and then bends the bent piece as shown in FIGS. 12 (c) and 12 (d). 18 is made to protrude and the peripheral edge of the pocket piece P is attached to the gauge plate 10.
It is bent to the back surface side along the outer shape of (S7).

Next, the CPU 63 on the setter side presses the holding plate 13.
Is raised (S8), and as shown in FIG. 12 (e), the pattern Pa of the pocket piece P is photographed by the TV camera 61 in that state (S9), and the image data of the pattern Pa is stored in the RAM 65.
(S10). At this time, the pocket piece P is held by the gauge plate 10 and the bent piece 18 by folding the peripheral edge thereof below the gauge plate 10. Subsequently, the program proceeds to the pattern deviation amount determination routine shown in FIGS. 10 and 11, and the deviation amount of each pattern Wa, Pa is calculated. That is, by the initial setting operation, the clamp 35 is arranged at the neutral position shown in FIG. 3, and the rotation angle θ thereof is set to “0” (S11).
Performs the calculation according to the following equation (1) (S12).

[0029]

[Equation 1]

Here, g (x, y) is a predetermined coordinate (x,
y) represents the brightness of the handle Wa of the front body W in G), and G (x,
y) represents the brightness at the position where the front body W is rotated from the position of the coordinates (x, y) about the rotation center of the main support 20 by a predetermined angle θ.

Next, the setter side CPU 63 uses the following equation 2
Is calculated (S13).

[0032]

[Equation 2]

Here, f (x, y) represents the brightness of the handle Pa of the pocket piece P at predetermined coordinates, and Z is a correlation function. At this time, Z (m, n) is x1≤x≤x2, y1≤
It represents the degree of pattern matching in the region of y ≦ y2, and is a function of the parameters m and n. In addition, the area (numerical value x
1, x2, y1, y2) are preset within a range in which the clamp 35 does not collide with the support member 7 or the like. Then, the deviation amounts m and n when the value of Z becomes the minimum are obtained, and the respective values Z, m, n, and θ are stored in the RAM 65 (S1).
4). In addition, m and n are the volume W in the X and Y directions.
It represents the amount of deviation between a and Pa.

Subsequently, the setter-side CPU 63 performs an addition process of an angle corresponding to the unit rotation angle Δθ of the clamp 35 (S15). Next, it is determined whether or not the rotation angle θ after the addition is equal to or larger than the maximum rotation angle θmax. In the plus θ direction which is mechanically determined (S16). Then, until the determination result is YES, the values S, Z when the clamp 35 is rotated by the unit rotation angle Δθ in the plus θ direction by repeatedly performing the processing of S12 to S16.
m, n and θ are sequentially obtained and stored in the RAM 65 each time.

Subsequently, the turning angle θ of the clamp 35 is set to "0" again (S17), and the setter side CPU 63 performs the calculation according to the mathematical expression 1 (S18). Then, f (x,
y), G (x, y) deviation amounts m, n are obtained (S19),
The obtained respective values Z, m, n, θ are stored in the RAM 65 (S20).

Next, the setter-side CPU 63 performs a subtraction process of the angle corresponding to the unit rotation angle Δθ of the clamp 35 (S21), and the rotation angle θ after the subtraction is mechanically determined in the minus θ direction. It is determined whether or not the rotation angle is less than or equal to θmin. (S22). Then, until the rotation angle θ after the subtraction becomes equal to or smaller than the minimum rotation angle θmin. In the minus θ direction (S22, YES), the processes of S18 to S22 are repeatedly executed to unitize the clamp 35 in the minus θ direction. Each of the above values Z when rotated by the rotation angle Δθ,
m, n, θ are sequentially obtained, and their values are calculated in the RAM 6 each time.
Store in 5.

After that, in the final step S23 of the pattern deviation amount determining routine, the sensor side CPU 63 selects from among the plurality of Z values obtained by the above-mentioned calculation, each value m when the Z value becomes the minimum. Search for n and θ, and use it for both patterns W
It is set as deviation amount data in each direction of a and Pa. Subsequently, the program returns to the main routine, and the setter-side CPU 63 drives the pulse motors 22, 28, 32 based on the deviation amount data in S24 of FIG. As a result, the front body W is moved together with the clamp 35 in each direction X, Y, θ, and the handle Wa is matched with the handle Pa of the pocket piece P.

Next, when the start switch 68 is operated (S25, YES), the setter side CPU 63 lowers the support member 7 against the spring 36 for urging the clamp 35, as shown in FIG. 13 (a). Then, the gauge plate 10, the bent piece holding plate 16 and the pocket piece P are brought close to the front body W (S26). In that state, the setter side CPU 63 is shown in FIG.
As shown in FIGS. 3 (b) and 3 (c), after each bent piece 18 is separated from the pocket piece P, the bent piece holding plate 16 is lifted and separated from the pocket piece P (S27). At this time,
The pocket piece P is pressed against the front body W by the gauge plate 10.

Then, as shown in FIG. 13D, after the clamp 35 is raised, a predetermined gap is formed between the needle 2 of the sewing machine 3 and the table 1, and the setter side C
The PU 63 drives the work holder moving AC servomotor 56 via the sewing machine side CPU 51 to move the work holder 5 onto the gauge plate 10, and the work holder 5 moves the gauge plate 10 and the pocket piece P onto the front body W. (S28). Next, as shown in FIG. 13E, the setter-side CPU 63 moves the gauge plate 10 below the support member 7 and separates it from the pocket piece P (S2).
9).

With the work holder 5 pressing the pocket piece P and the front body W against the work cloth supporting surface 1a, the setter side CPU 63 moves the work holder 5 back to the needle drop point via the sewing machine side CPU 51. (S3
0). At this time, the support member 7 is moved to the upper standby position, and the pocket setter 6 returns to the initial state.

Next, the sewing machine side CPU 51 reads the sewing pattern data from the RAM 53 and drives the work holder moving AC servo motor 56, the sewing machine moving AC servo motor 57 and the sewing machine motor 58 in accordance with the data to move the pocket piece P to the predecessor. Sewing is fixed to W (S3
1).

On the other hand, when a satisfactory result cannot be obtained by the automatic pattern matching operation due to the balance between the resolution of the TV camera 61 and the fine density of each pattern, the start switch 68 as shown in FIG. 9 is used. If each jog key 69 is operated before operating (S32, YES), the setter side CPU 63 is selected according to the type of the operated jog key 69.
Thus, the clamp 35 is moved in each direction for each unit movement amount (S33). Therefore, the operator can finely adjust the pattern matching while visually checking the patterns Wa and Pa of the front body W and the pocket piece P (S32).

As described above, in this embodiment, the front body W
In order to match the patterns Wa and Pa of the pocket pieces P, the front body W is moved in three directions X, Y, and θ, so that both patterns Wa and Pa have a complicated shape like a checkered pattern. Even if they do, they can be surely matched without requiring skill. Further, since the front body W is moved in order to perform the pattern matching, it is not necessary to change the arrangement position of the pocket piece P, so that the sewing pattern data representing the relative position between the work holder 5 and the needle 2 can be obtained. Therefore, it is not necessary to perform a troublesome arithmetic process of processing the pocket pieces P in accordance with the change of the arrangement.

The present invention is not limited to the above embodiments, but can be embodied in the following modes.

(A) As shown in FIGS. 7 (b) and 7 (c), a pocket piece P provided with horizontal and vertical stripe patterns Pa and Wa.
And when performing pattern matching of the front body W, clamp 35
Drive control in either one of the X direction and the Y direction, which corresponds to the direction and the stripe formation direction.

That is, in the case of the vertical stripe pattern shown in FIG. 7B, the pattern can be aligned by moving the clamp 35 in the θ direction and the X direction. On the other hand, in the case of the horizontal stripe pattern shown in FIG. 7C, the clamp 35 is placed in the θ direction and the Y direction.
Patterns can be matched by moving. For this reason, a selection switch may be provided to select the moving direction of the clamp 35 in accordance with the vertical stripes and the horizontal stripes, and to discriminate the deviation amount only in two directions of the θ direction and the X or Y direction. in this case,
Since the deviation amount is discriminated in only two directions, the calculation processing speed is faster than that in the above-described deviation amount discrimination in three directions.

(B) The pocket piece P should be moved during the pattern matching operation of the front body W and the pocket piece P.

(C) Both the front body W and the pocket piece P should be moved during the pattern matching operation.

(D) To embody a processing machine in which two work cloths are fixed by rivets.

(E) To embody a processing machine in which two work cloths are fixed by an adhesive.

[0051]
