BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called pocket setter or the like in which pockets are set on a body cloth so that they can be sewn, and a peripheral portion of a pocket cloth to be placed on the body cloth is predetermined. The present invention relates to a pocket cloth folding device adapted to be bent along the pocket shape.

[0002]

2. Description of the Related Art When forming a breast pocket of a shirt or the like, the peripheral edge portion W11 of a pocket cloth W1 is bent as shown in FIG. 9, and the cloth cloth W2 is polymerized and held.
The procedure is to form a stitch along the peripheral edge W11 with a sewing machine. At this time, when each procedure is manually performed, two people are required to bend the pocket cloth W1 and two are required to perform the sewing operation.
It requires about 3 personnel and the manufacturing cost is extremely high.

Therefore, at present, a pocket setter PS as shown in FIG. 10 is used to reduce the labor and efficiency of the pocket sewing work. This pocket setter PS
Is provided with a folding device 2 above one end of the sewing machine table 1, and the folding device 2 automatically makes the pocket cloth W1.
Bend the peripheral part W11, and the folded pocket cloth W1
Are superposed on the body material W2 placed on one end of the sewing machine table 1, and these works (body material W2 and pocket cloth W1) are slid along the sewing machine table 1 to the sewing portion of the sewing machine main body 3. I am supposed to send it. In addition,
The work sent to the sewing section of the sewing machine body is indicated by X in the figure.
The stitches are formed along the peripheral edge portion W11 of the pocket cloth W1 by moving on the sewing machine table together with the cloth pressing member that is moved by the Y drive mechanism.

As described above, according to the pocket setter SP, everything from the bending of the pocket cloth W1 to the sewing operation can be automatically performed, and high productivity can be obtained. In particular, the folding work of the pocket cloth W1 is a complicated and time-consuming work by manual work, and the effect of being automated is extremely large.

FIG. 11 and FIG. 12 are views showing a concrete structure of the bending apparatus for the pocket cloth. In FIG. 11, 1
The reference numeral 1 designates a turntable which is rotatably instructed by the support body 12, and is turned by an air cylinder 13 about a fulcrum 12a in the vertical direction. Reference numeral 14 denotes a template holding arm rotatably supported by the rotary table 11, which is moved by an air cylinder 15 in the front-rear direction. Reference numeral 16 denotes a template fixed to the tip of the template holding arm 14, and the template 16 has substantially the same outer shape as the pocket to be formed in the body cloth W2. Reference numeral 17 denotes a folding plate holding arm rotatably connected to the projecting portion of the rotary table 11, which can be vertically rotated by an air cylinder 18.

Reference numeral 19 denotes a mounting plate fixed to the tip of the folding plate holding arm, which has a U shape capable of enclosing the template plate as shown in FIG. Cylinders 20-24 are provided. 25-
Reference numeral 29 is a folding plate attached to the plunger of each of the air cylinders 20 to 24. Of these, the three folding plates 25, 26, and 27 are attached to the mounting plate 19 around the template 16.
Are arranged so as to face the side portions of the template 16 when they are positioned, and the remaining two folding plates 28 and 29 are the template 1
The folding plates 28 and 29 are bent at the same angle as the bent portion 16a of the template 16 and the corners thereof.

When the pocket cloth W1 is bent by the device having the above-mentioned structure, first, the pocket cloth W is
The pocket cloth W1 is placed so that the peripheral edge portion W11 of No. 1 uniformly projects from the template. At this time, the air cylinder 20,
21, the template holding arm 14 and the folding plate holding arm 17 are both in the raised position shown in FIG.
The mounting plate 19 is located above the template 16.

Next, the mounting plate 19 is lowered by the air cylinder 18 to a position surrounding the template 16. At this time, the air cylinders 20 to 24 provided on the mounting plate 19
All of the plungers are in the retracted state, and the folding plates 25 to 29 held by the plungers are held slightly below the sides and the bent portions of the template 16. As a result, the pocket cloth W1 protruding outward from the template 16
The peripheral portion of the state is changed from the state shown in FIG.
As shown in FIG. 3, the mold plate 16 is bent downward along the outer shape thereof.

Next, the plungers of the air cylinders 20 to 24 project, and the folding plates 25 to 2 provided on the respective plungers.
9 projects inward of the template 16. As a result, the pocket cloth W1 bent downward is bent toward the lower surface side of the template 16 by the folding plates 25 to 29 (see FIG. 13C). After that, the template 16 and the mounting plate 19 are lowered by the action of the air cylinder 13, and the pocket cloth W1 is superposed on the body cloth W2 through the folding plates 25 to 29 (see FIG. 13D).

Then, after that, each air cylinder 20-2
The plunger of No. 4 becomes immersive and the folding plates 25 to 29
Moves backward together with the template 16, and the peripheral edge W1 of the pocket cloth W1
1 directly polymerizes on the upper surface of the body material (see FIG. 13 (e)). Here, the template 16 is a pocket cloth W1 and a body cloth W.
While pressing 2, move along the upper surface of the sewing machine table 1 to position the pocket cloth W1 and the body cloth W2 at the sewing portion of the sewing machine body 1. Then, the cloth pressing member 4 held above the stitched portion descends on the pocket cloth W1 and presses it. Then, the template 16 is removed from the pocket cloth W1 by the action of a cylinder (not shown) (see FIG. 13 (f)), and returns to the initial position.

[0011]

As described above, in the conventional pocket cloth folding apparatus, since the pocket cloth W1 is automatically folded, the labor saving and the improvement in productivity are achieved. However, if the pocket cloth to be handled has a portion (thick cloth portion) where the cloth thickness suddenly increases, wrinkles and flexure occur at the peripheral portion of the folded pocket cloth W1. However, there was a case where a proper bent state could not be obtained.

For example, as a thick cloth portion, a pocket cloth W1 having a piping portion WP as shown in FIG. 14 is formed.
When the folding plate 27 is bent, the folding plate 27 abuts on the piping portion WP as shown in FIG. 15, but hardly contacts other portions, so that only the piping portion WP of the peripheral edge portion W11 of the pocket cloth W1 is pulled. As shown in FIG. 16, the pocket cloth W1 had wrinkles Wa around the piping portion WP.

Further, when the pocket cloth W1 is folded along each side of the template 16, the bent portion thereof is shown in FIG.
A surplus portion (thick cloth portion) Wb is formed as shown in FIG.
Ideally, this excess portion Wb is desirably folded as shown in FIG. 9B, but since the conventional folding plate has a bent shape that is substantially the same as the bending portion of the pocket, this folding plate is When the surplus portion is pressed by, the ideal folded state as described above is rarely obtained, and in many cases, it is crushed irregularly as shown in FIG. 17 (c) or (d). And the pocket cloth W1 or the body cloth W after the flexure is sewn up.
2 and the quality of the sewn product was significantly deteriorated.

The present invention has been made in view of the above problems, and even when a thick cloth portion is formed on the pocket cloth, the peripheral edge portion of the pocket cloth can be bent properly. The purpose is to provide a bending device.

[0015]

According to the present invention, a pocket cloth is placed on a template having substantially the same shape as a pocket to be formed,
The peripheral edge protruding from the template is projected along the side edge of the template by causing the folding plate provided on the peripheral edge of the template to project inward of the template. In a pocket cloth folding device adapted to be bent to the lower surface side of a template, a folding plate provided at a position facing the side of the template is provided with a thick cloth portion formed on the peripheral edge of the pocket cloth. A groove portion that can be accommodated is formed.

Further, in order to achieve the above object, a groove is formed in the folding plate disposed so as to face the bent portion of the template, and the groove always forms an excess portion formed in the bent portion of the pocket cloth. You may make it fold while guiding in a fixed direction.

[0017]

In the present invention, when the peripheral edge portion of the pocket cloth is folded by the folding plate, the thick cloth portion formed on the pocket cloth is accommodated in the groove portion of the folding plate. Since the pocket cloth is folded while being in uniform contact with the peripheral edge portion, wrinkles do not occur at the peripheral edge portion of the folded pocket cloth. Further, when the pocket cloth is folded along the side of the template, the thick cloth portion of the pocket cloth formed at the bent portion is guided and folded in the groove formed in the folding plate for folding the pocket cloth. Therefore, irregular wrinkles and bending are not generated in the thick cloth portion, and the quality of the sewn product is significantly improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
It will be explained based on. It should be noted that the same or corresponding parts as those of the above-mentioned conventional technique are designated by the same reference numerals, and detailed description thereof will be omitted.
The folding device for the pocket cloth W1 according to this embodiment is similar to that shown in the above-mentioned prior art, in which the rotary base 11, the template holding arm 14, the folding plate holding arm 17, and the air cylinders 13, 15, for driving these, are provided. 18, the mounting plate 19, and the air cylinders 20 to 24 attached to the mounting plate 19, and the like. The air cylinders 13, 15, 18 raise and lower the template 16 and the mounting plate 19, and the mounting plate 1
The folding cylinders 30 to 34 can be made to project from the outside of the mold plate 16 toward the inside of the mold plate 16 by the air cylinders 20 to 24 provided in 9. However, in this embodiment, the folding plates 30, 32, 33, 34 are configured as follows, which is different from that shown in the prior art.

That is, in this embodiment, the template 1
Folding plate 3 arranged so as to be able to face both sides of 6
0 and 32, the groove portions 30a and 3 as shown in FIGS.
2a is formed. These groove portions 30a and 32a are pocket cloth W1 which has been subjected to piping sewing WP as shown in the drawing.
It is formed on the assumption that the peripheral edge W11 of the pocket cloth W1 is bent, and the dimension and shape thereof are the peripheral edge W11 of the pocket cloth W1.
Has a width and a length capable of accommodating the piping portion WP formed on the peripheral portion W11 when the is bent (see FIG. 2).

The folding plates 33 and 34 arranged so as to face the bending portion 16a of the template 16 have side portions that bend at the same angle as the bending portion of the template, as in the conventional folding plate. As compared with the plate bodies 33 ′ and 34 ′ (see FIG. 4) provided,
The V-shaped groove portions 33a and 34a are formed as indicated by the diagonal lines. The inner surfaces 33a1 and 34a1 on one side of the groove portions 33a and 34a are formed on the bent portion 16a of the template 16,
16a, and the forward / backward direction X of the folding plates 33, 34
Is inclined with respect to an imaginary line L parallel to
It is located on an extension of the side portion.

As described above, in this embodiment, the groove portions 30a, 32 are formed in the folding plates 30, 32, 33, 34, respectively.
Since a, 33a, and 34a are formed, even if the pocket cloth W1 is sewn by piping, the peripheral edge can be bent properly without wrinkles. That is, the mounting plate 1
When 9 is lowered to the vicinity of the mold plate 16, the pocket cloth W1 placed on the mold plate 16 is moved downward by the folding plates 30 to 34 in the retracted position as in the state shown in FIG. Can be folded. Here, when each folding plate is projected, the peripheral edge portion W11 of the pocket cloth W1 is moved to each folding plate 30.
Are pressed by ~ 34 to be bent to the lower surface side of the template 16, at this time, the piping portion WP as the thick cloth portion protruding downward from the pocket cloth W1 is the folding plates 30, 32.
The upper surface of the groove portion 30a, 3a as shown in FIG.
It is stored in 2a. Then, the upper surfaces of the folding plates 30 and 32 come into contact with the pocket cloth W1 other than the piping portion WP, and the contact area is greatly expanded as compared with the conventional case, so that the force applied to the pocket cloth is dispersed and uniformized. The gap t2 formed between the pocket cloth W1 and the folding plates 30, 32 is considerably narrower than the conventional gap t1. Therefore, wrinkles and bending elements are greatly reduced, and as a result, a flat and proper bent state can be obtained.

When the pocket cloth W1 is folded along the peripheral edge of the template by the folding plates 30, 31, 32, an extra portion Wb as shown in FIG. 17A is formed at the bent portion. However, since the excess portion Wb is guided in a constant direction by the inner side surface 33a1 of the groove 33a and is always folded in one direction in a flat state as shown in FIG. 6, wrinkles and flexure are not generated. Absent. Further, the groove portion 34a also has the same effect. Therefore, according to this embodiment, it is possible to properly fold all the peripheral edge portions W11 of the pocket cloth W1, and by sewing the body cloth in this state, a high quality product can be obtained.

Although the folding plates 30 to 34 are formed of a single member in the above embodiment, the folding plate 40 is used as in the second embodiment shown in FIG. 7A. May be formed by two plate-shaped members 41 and 42, and the facing interval 40a may be a groove. In this case, a height is provided between both plate-shaped members 41, 42, and the difference in height is the difference between the cloth thickness t2 at the edge of the opening and the cloth thickness t3 at the other end of the pocket cloth W1 (t2-t3). If set to, the gap between the lower surface of the pocket cloth W1 and the folding plate 40 can be completely removed in the folded state (see FIG. 7 (b)), and bending of the cloth and generation of wrinkles are more reliable. Can be prevented.

FIG. 8 is a diagram showing a third embodiment of the present invention. In the third embodiment, as with the second embodiment, the folding plate 50 has two plate-shaped members 5 having a height difference.
1, 52, and each plate-shaped member 51, 5
2 is slidably provided with respect to the mounting plate 53 so that the width of the groove 50a formed between the plate-shaped members 51 and 52 can be adjusted. According to this, even when the width or the position of the piping sewing portion WP changes, this can be dealt with, and a product having excellent versatility can be obtained.

The template 1 is used in the first embodiment.
Grooves were formed in both of the folding plates 30, 32 facing the side of 6 and the folding plates 33, 34 facing the bent portion, but either one of the folding plates 30, 32 or 33,
Even if the groove is formed only in 34, the quality of the sewn product is obviously improved as compared with the conventional device.

In the above embodiment, the folding operation of the pocket cloth W1 having a substantially rectangular shape is targeted, but the present invention can be applied to the pocket cloth W1 having other shapes. For example, it is also applicable to a pentagonal pocket cloth W1 and the like. Of course, in this case, it is desirable to provide a folding plate for folding each surplus portion formed in each bent portion.

[0027]

As described above, according to the present invention, the peripheral edge portion of the pocket cloth supported by the template is formed by the plurality of folding plates provided so as to advance and retreat with respect to the template supporting the pocket cloth. In a folding device for a pocket cloth, which is adapted to be bent along a line, a groove is provided in a folding plate disposed on the side of the template, and when the peripheral edge of the pocket cloth is bent, the peripheral edge of the pocket cloth is Since the formed thick cloth portion is accommodated in the groove portion, the peripheral edge portion of the pocket cloth can always be bent in an appropriate state without wrinkles, and a high quality pocket can be formed.

Further, a groove portion is formed in the folding plate arranged so as to face the bent portion of the template, and the thick cloth portion formed in the bent portion of the pocket cloth is always guided in a fixed direction by the groove portion. If it is folded while being folded, irregular wrinkles and bending will not occur at the bent portion, and it is possible to expect a great improvement in quality.
