Conventionally, when assembling and sewing a waist belt of a belt-like bag to the body of a cylindrical sewn product such as a skirt, mechanical handling is difficult because the fabric of each part is flexible and has an irregular shape. Previously, this type of assembly suture depended entirely on the manual labor of skilled workers with dexterous hands, but in order to improve productivity, the inventors of the present application have developed a temporary ``Sewn product parts support structure'' and ``automatic assembly sewing control device'' were invented, and patent applications were filed in 1980.
-179488 and Japanese Patent Application No. 179489/1983.

ンにより組立縫合するよう構成されていた。 A detailed explanation will be omitted to avoid duplication with the cited document, but as shown in FIG. A skirt body etc. is supported in a cylindrical shape on a body support 1 made of support pieces 21 that can be expanded/reduced in the radial direction, and the tip of the waist belt of the belt-shaped bag is inserted from the tangential direction of the circumference of the upper end of the cylinder. It was configured to be engaged with a leading guide rod 38 and guided around the skirt body rotating together with the support, while being assembled and sewn by a stationary sewing machine.

た。 However, in the configuration of the proposed example as described above, the leading guide rod 38 tries to pull the belt around it by the rotation of the skirt body, but the belt does not curve along the circumference. , the sewing machine tends to move toward the line connecting the points of application with a straight line, which disturbs the correct relative position of the body and the belt, and the difference in circumferential length between the two may cause poor sewing quality such as wrinkles.
つぎに、その概要を説明する。 Next, the outline will be explained.

is a lockstitch sewing machine in which the needle is mounted on a support stand so that it can move horizontally.The support stand can move up and down/back and forth, respectively, but during sewing it operates while remaining stationary at a predetermined position. S is a body support body which can be expanded/contracted and rotates around a vertical axis, on which a cylindrical sewing fabric (in this example, a skirt body item) 2 is set; rotates with.
1 is a sewn product fabric 1 that is a belt-shaped bag (in this example, it is a waist belt of a skirt)
Then, the guide stand device G moves the needle drop section 1 of the sewing machine M along the upper edge of the rotating skirt body 2.

３を制御することによつて行われる。 FIG. 5 shows the main part of a body support S having basically the same structure as the conventional proposed example shown in FIG. 7, in which a pair of comb rings 21 slide up and down on a support shaft 20. By doing so, the plurality of support pieces 3 arranged radially in the shape of an umbrella can be expanded/reduced as shown by the two-dot chain line in the figure. As shown in FIGS. 2 to 5, an air cylinder (large cylinder 4) is fixed on each support piece 3, the tip of the piston rod forms a guide rod 6 for the waist belt 1, and the lower part of the piston rod forms a guide rod 6 for the waist belt 1. A joint 5 is fixedly installed, and a clamp 8 is rotatably attached around a rotating shaft 9. Second
The figure shows the clamp 8 in an open state, and FIG. 3 shows the state in which it is closed and grips the fabric. This rotation is caused by each joint 5
It is configured to be operated by an air cylinder (referred to as a small cylinder 7) attached via a bracket 5a (FIGS. 2 and 3). The operation of the large and small cylinders 4 and 7 is controlled by opening and closing the micro switch 25 using the cylinder switch cam 22 (FIG. 5) which rotates together with the support S.
This is done by controlling 3.

However, in the above configuration,
Although the misalignment of the relative positions of both fabrics was significantly improved,
Shape both pieces of dough into a cylindrical shape in advance,
When moving the fabrics so that they are sandwiched together correctly and sewing them together with a sewing machine (the same applies when both fabrics are fixed and the sewing machine is moved), there is naturally a difference in inner diameter/outer diameter in the multiple layers of the waist belt fabric. However, due to the excessive length of the inner fabric, sagging occurs, which tends to concentrate locally and cause wrinkles.

The gripped point C is the point where the grip is released just before being stitched by the sewing machine M (Fig. 6), and the point D is the point where the grip is released just before the sewing machine M stitches the body 2.
The point E where the and belt 1 are integrated is a point where the sewn fabrics 1 and 2 are pulled toward the center of the arc and deformed, eliminating the force that inhibits machine stitching from being exerted on the machine stitching point. , the point at which the support piece guide rod 6n re-supports, and F indicates the leading point of this series of operations that have passed through the above-mentioned operating points.

It has a half-moon shape and fits and engages with the circumferential portion of each guide rod 6n to strengthen the gripping force on the cloth, and at the same time, it creates a uniform sag in the inner cloth 1a of the belt 1 (the excess difference in inner diameter). It is designed to absorb Guide rod 6
The diagonally shaded parts -1 to 6-4 and 6-8 to 6-11 respectively project upward from the plane of the paper and support both fabrics 1 and 2.

れて吸収される。 As described above, the wrinkles that conventionally occur in one or two places during sewing due to the difference between the inner and outer diameters of the waist belt 1 can be seen in the example shown in this figure, where the slack is substantially reduced to 24. Since it is evenly distributed over the areas, wrinkles and the like will not occur. In other words, the inner cloth 1 due to the difference in the inner diameter and outer diameter of the belt 1
There is no accumulation of slack in a at the suture area,
The slight slack in the inner cloth 1a between the guide rods 6-6 and 6-7 at points C and D is absorbed by being forcibly sewn in one after another.
