る。 For example, when performing secondary sewing processing such as pants (briefs), pants bottoms, or panty pants,
One of the well-known sewing processes is to sew a thin ring-shaped fabric with stretch elasticity, which has been formed into a ring shape in advance, to the cylindrical waist part to create a stretchable waist part. However, conventionally, this sewing operation involves straightening the two parts manually and then sewing them together using a sewing machine, which is problematic in that it requires time and effort. That is, FIGS. 1 to 4 illustrate a typical example of sewing an annular fabric to the edge of such a cylindrical fabric, in which an elastic annular fabric is sewn to the waist part of pants (briefs). 1 is the pants, 1a is the front part, 1b
1c is the back body part, and 1c is the waist part extending over the front and rear body parts 1a and 1b, to which, as is known, an annular fabric 2 having stretchable elasticity is sewn together to form a waist that can be freely stretched and tightened. I will do it. As is well known, when the pants 1 are unfolded as shown in FIG. 1, the edge of the waist portion 1c at the back body portion 1b is not straight but shaped like a convex arc as shown in FIG. The circular fabric 2 to be sewn is made of a tape-like fabric with elasticity such as rubber thread or spandex, A single-loop type fabric 2a, which is made into a ring as shown in Figure 3A and sewn together at both ends, and a double-loop type 2b, which is folded in half and made into a ring, as shown in Figure 3B. However, in both cases, these annular fabrics 2 are attached to the edge of the waist part 1c of the pants 1.
As shown in FIG. At this time, since all of these annular fabrics 2 have a straight shape, it is difficult to sew these annular fabrics 2 together when the edge of the waist portion 1c is curved as shown in the second figure. In the end, as shown in Figure 4, the overlapping seams of the two parts are straightened and overlapped by hand, and this is fed into the lower end of the presser foot 4 of the sewing machine sewing section to perform sewing. In the case of pants 1, etc., a considerable amount of labor and work time are consumed, which is not desirable from the point of view of efficiency, and in the case of this type of secondary processed sewn product, an automated line is required from fabric cutting to sewing processing. Nowadays, it is necessary to eliminate the manual processes of workers as much as possible and save labor and improve efficiency through automation.

レータによる重合手段とを含む点にある。 In response to such demands, the present invention completely automates the process of overlapping the annular fabric on the edge of the cylindrical fabric and sewing the overlapping part, and automatically straightens the sewn part at this time. It is designed to be carried out accurately and easily, and its characteristic feature is that when the annular fabric is superimposed on the edge of the cylindrical fabric and the two are sewn together, each piece of fabric is formed so that it can be expanded and contracted freely. The edge of the cylindrical fabric and the annular fabric are each stretched separately on the circumferential stretching route and held in a predetermined overlapping relationship, and the edge of the cylindrical fabric is provided with a step whose height is variable in a part of the route. The annular fabric is straightened along the linear guide surface formed by the process, and the annular fabric is superimposed on the linearized edge via a separator placed on the guide surface that can move forward and backward, and then passed through the sewing section of the sewing machine. This feature automatically sews the linearized overlapping portions of the two, and its unique feature is the circumferential stretching of the edge of the cylindrical fabric by a plurality of support roller groups arranged to be able to expand and contract freely. A circumferential tensioning path for the annular fabric using a plurality of groups of support pins that can be expanded and contracted and moved forward and backward in the axial direction like the hoisting path, and arranged in the circumferential path for the edge of the cylindrical fabric in front of the sewing section of the sewing machine. edge straightening means using a pair of fixed and movable edge guides that cross each other with a step; and a separator that is arranged on top of the upper surface of the edge guides so as to be movable forward and backward, and that supports the annular fabric and presses the edge of the cylindrical fabric. and polymerization means by.

そのまま掛けることはいうまでもない。 FIG. 6 shows each support roller 7a to 7 shown in FIG.
When the edge 6a of the cylindrical fabric 6 is stretched over group d, when the edge 6a has a convex arc-shaped curve as shown in the figure, the edge 6a' shown by the dotted line, This shows that the roller is stretched over the circumferential surface of the roller while being corrected into a reverse concave arc shape, and the 10th and 1st
1 shows that the edge 6a of the cylindrical fabric 6 and the inner edge of the annular fabric 2 are linearly overlapped and sewn together by the method of the present invention as described later, and this progresses sequentially to form a sewn part 3.
If the first portion of the guide mechanism 9 approaches the guide mechanism 9, subsequent sewing will not be possible unless the separator 12 in the guide mechanism 9 is retracted. As a means for retracting the separator 12, a sensing member 19 for sensing the approach of the sewn portion 3 is disposed as shown in the figure, and the sensor 20 is connected to the unsewn edge 6a.
It is inserted between the annular fabrics 2, and the sewn part 3 is detected by a sensor 20, and the sensor 20 is moved back, and at the same time, the separator 12 is moved back to avoid collision with the sewn part 3, etc. The method used is as follows. Moreover, what is shown in FIG. 12 is a case where the annular fabric 2 has a seam 21 by sewing to join the two ends of the annular fabric, and when such an annular fabric 2 is used, When sewing the end edge 6a of the cylindrical fabric 6 and the annular fabric 2 in a straight line, the sewing start point is set at the seam 2.
1, and as the sewn portion 3 progresses one by one and the seam portion 21 approaches the separator 12, the sensing member 22, which is a reflective phototube, detects the shade depending on the thickness of the fabric shown in FIG. Accordingly, the separator 12 is moved backward when the seam 21 is sensed, thereby preventing the seam 21 from colliding with the separator 12. Further, FIG. 13 illustrates a case where a plurality of sets of guide mechanisms 9 according to the present invention are provided, and depending on the curve form of the edge 6a of the cylindrical material 6, the guide mechanism 9 may be guided by a fixed edge guide 10 and a movable edge guide 11 as shown in the figure. mechanism 9-1,
Two or more sets can be provided as shown in 9-2, and when the edge 6a shown in FIG. It goes without saying that the end edge 6a is curved in a convex arc shape as shown by the solid line, and if the end edge 6a' is in a curved shape from the beginning, the end edge 6a is hung as is.

The lower left and right support rollers 7c and 7d, which are used to expand, contract, and close, are rotatable brackets 28, 28 whose respective ends are pivotally supported on a tension cam plate 27 which is rotatably supported on the fixed base 24 and equipped with an adjustment plate 25 and an adjustment lever 26. The guide links 29, 29 attached to one end of the support rollers 7c, 7d are slidably connected by a slide guide link 30 via a pin or the like that engages with a long hole. On the other hand, in the support pins 8a to 8d, the upper left and right support pins 8a and 8b are connected to the support roller 7 at the left and right upper ends of the fixed base 24.
Bracket 31 pivoted on the same axis as a and 7b,
The support pins 8a, 8b are connected to advance/retreat brackets 33, 33, respectively, and the support pins 8a, 8b are engaged with the support rollers 7a, 31 so as to be movable in the axial direction. Lower left and right support pins 8c, which can move forward and backward independently only in the axial direction while maintaining their relative position with respect to the support pins 8a and 7b, and can be expanded and contracted and closed with respect to these support pins 8a and 8b;
8d are respective elongated holes 35 of the brackets 34, 34 extending coaxially with the variable support rollers 7c, 7d.
The support pins 8c, 8d are engaged with rotating brackets 36, 36, which are engaged in the axial direction to be movable in the axial direction, and each end of which is pivotally supported by the tension cam plate 27. ,3
By connecting 7, the variable support roller 7
It expands, contracts, and closes together while maintaining its relative position with c and 7d, and is also provided so that it can freely move forward and backward in the axial direction. In order to expand/contract/close the variable support rollers 7c, 7d and the variable support pins 8c, 8d, and move the support pins 8a, 8b, 8c, 8d back and forth in the axial direction, the respective advancing/retreating brackets 33, 33 are used. The other ends of the two-pronged operating link 38 are pivotally connected to each other through a long hole and a pin shaft that engages therewith, and the pair of bifurcated operating links 38, 38 are pivoted on a common operating shaft 39. The roller 41 of the actuating arm 40 protruding downward from the pivot portion of the actuating shaft 39 is engaged with the cam groove 43 of the rotatable cam 42, and the shaft 44 of the cam 42 is engaged with the cam groove 43 of the rotatable cam 42.
This is done by rotating the drive motor 45 via an interlocking gear train 46 or the like. At this time, the supporting rollers 7a to 7d, which stretch the edge 6a of the cylindrical fabric 6, have their peripheral surfaces roughened as shown in Figure 15 to ensure reliable holding and movement of the edge 6a. It is preferable. According to this cam and link mechanism, each of the support rollers 7a to 7d groups and the support pins 8a to 8d group shown by solid lines in FIG. The cylindrical material 6 is placed over each of the support rollers 7a to 7d occupying the four corner positions so that the outer end of its edge 6a is connected to and supported by the linear end surface 10b of the fixed edge guide 10 in the edge mechanism 9 described above. Each support pin 8 is fitted and tensioned.
The annular fabric 2 is fitted and stretched over the groups a to 8d, and since they are in the contracted and closed state, the fitting and stretching can be easily carried out. Next, in order to open these, the rotation of the cam shaft 44 due to the drive of the drive motor 45, the displacement of the cam groove 43 due to the rotation of the cam 42, and the rotation of the cam groove 43 through the rollers 41 that engage with the rotation of the cam shaft 44 and the rotation of the cam 42 are required. Due to the rotation of the fork-shaped operating link 38 about the operating shaft 39, the advancing and retracting brackets 37, 37 are rotated from the solid line position to the chain line position as shown in the dashed line position, whereby the rotating brackets 36, 28 are moved together. The lower left and right support rollers 7c, 7d and support pins 8c, 8d are similarly pulled down and expanded from the solid line position to the chain line position, thereby allowing the support rollers 7a to 7d and support pins 8a to 8d to rotate. The tension path is expanded as shown, and the edge 6a of the cylindrical fabric 6 and the annular fabric 2 are supported under tension under tension suitable for sewing. Further, due to the rotation of the cam 42, the fork-shaped operating link 38 moves as shown by the chain line from the solid line in FIG. Everything goes backwards,
As shown in the figure, only the upper, lower, left, and right support pins 8a to 8d move back synchronously in the axial direction, so that the annular fabric 2 is superimposed on the outer end of the edge 6a of the cylindrical fabric 6 with a predetermined overlap width. It is regulated as follows.
Along with this overlapping width regulation, the edge 6 by the edge mechanism 9
Both the straightened edge 6a and the annular fabric 2 overlapped with it under a predetermined width are straightened by the lowering of the sewing machine presser foot 4 in the sewing section of the sewing machine.
Through the clamping of the fabric and the feeding of the fabric by the feed plate mechanism, the fabric is successively drawn into the sewing section of the sewing machine and the fabric is sewn. The mechanism using the cam and link mechanism shown in FIGS. 14 and 15 is such that the pair of support rollers 7c, 7d and support pins 8c, 8d at the lower left and right of each group of support rollers 7a to 7d and support pins 8a to 8d simultaneously This is just one example of a movement mechanism for opening, expanding, contracting and closing, and the present invention does not feature this movement mechanism itself; it may also be based on a cylinder mechanism or the like, and the four support rollers 7a to
The group 7d and all the groups of support pins 8a to 8d may move forward and backward in the radial direction to expand, contract, and close at the same time, and in short, this opening, expansion, and contraction is a holding method suitable for sewing and automatic movement of the fabrics 6 and 2. Because it is for
Any movement mechanism other than the illustrated example may be used as long as it can achieve the purpose, and this is included as a design matter.

きる。 According to the present invention, the straightening of the edge 6a of the cylindrical fabric 6 and the overlapping sewing of the annular fabric 2 thereto are carried out as follows. That is, when sewing the annular fabric 2 such as a rubber-containing elastic tape fabric to the waist part 1c of pants (briefs) 1 as illustrated in FIGS. 1 and 2, in the present invention, first, as shown in FIG. The edges 6a of the annular fabric 2 and the cylindrical fabric 6 are stretched over the circumferential tensioning path formed by each group of support pins 8a to 8d and the circumferential tensioning path formed by each group of support rollers 7a to 7d, respectively. When the edge 6a of the cylindrical fabric 6 has a convex arc-shaped curve as shown in the sixth figure, it is straightened so that it becomes a concave arc-shaped curve as shown by the dotted line. In the case of a concave curve, it is spanned as is. At this time, as shown in FIGS. 14 and 15, each group of support pins 8a to 8d and the support roller 7
Groups a to 7d are in contracted and closed postures. In this way, both fabrics 2 and 6 are stretched, and at this time, in the edge mechanism 9, as shown in FIG. The annular fabric 2 is also set along the eighth line.
It is placed on the separator 12 which is in the forward position as shown in the figure. When set in this way, the end edge 6a is sensed by a sensing member 18 such as a reflective phototube that is activated when sensing for t seconds, and the lower left and right support rollers 7c,
7d and support pins 8c and 8d to drive an expansion/contraction movement mechanism as illustrated in FIGS. 14 and 15,
Both support rollers 7c, 7d and support pins 8c, 8d
By expanding and fluctuating the edge 6a downward,
Both the annular fabric and the annular fabric are supported under tension. Furthermore, each of the support pins 8a to 8 is moved to this expanded position through a two-stage operation of the forked actuating cylinder 38 in the movement mechanism as illustrated in FIGS. 14 and 15 through a time setting mechanism such as a timer.
By retreating in the axial direction with group d, the annular fabric 2 is retreated to a predetermined position via the fixed guide 17 shown in FIG. As a result, overlapping between the fabric 2 and the edge 6a is controlled. Next, the sewing machine presser foot 4 is lowered via a time setting mechanism such as a timer, the overlapping parts are clamped between the feed plate mechanism of the sewing section of the sewing machine, and the sewing machine starts sewing the overlapping parts. will be done. As described above, in the guide mechanism 9 disposed immediately before the sewing section of the sewing machine, the edge 6a rides on the movable edge guide 11, and its outer end is aligned with the fixed edge guide 10, as shown in the seventh and eighth figures. Since it is fed along the end surface 10b and the upper surface is pressed by the separator 12, the curved edge 6a is reliably straightened and its position is regulated on the straightened edge 6a. After passing through the separator 12, the annular fabric 2 undergoes linear polymerization, so that both are pulled into the sewing machine presser foot 4 side with complete linear polymerization and end polymerization of a predetermined width, and the overlapping portion is automatically sewn accurately and easily. will proceed sequentially. In this way, the edge 6a
The fabric 2 is a group of support rollers 7a to 7d and a support pin 8a.
〜8d group, and as shown in Fig. 10, the sewing part 3
When the starting position of the separator approaches the guide mechanism 9, the sewing part 3 will collide with the separator 12 and the sewing progress will be blocked. The approach of the leading end of the garment section 3 is sensed, and the separator 12 is moved back as the sensor 20 moves back, allowing sewing to be completed to the end. If the seam 21 is on the side of the annular fabric 2 as shown in FIG. As shown in FIG.
2, the separator 12 is moved backward, and the seam 21 is passed through and the final stitching is performed. When the straightening and sewing of the edge 6a and the entire circumference of the annular fabric 2 is completed, the sewing machine is started after a certain period of time has elapsed using a time setting mechanism such as a timer, starting from the retreat of the separator 12. is stopped, and the lower left and right support rollers 7c, 7d in the expanded position are retracted and closed via the expansion/retraction/closing movement mechanism shown in FIGS. It is removed. Thereafter, by repeating the process of attaching a new cylindrical fabric 6 and ring-shaped fabric 2 to the tensioner, it becomes possible to continuously and automatically perform the straightening and overlapping of the fabrics 6 and 2 and the sewing operation. In the above-mentioned operation, the movable edge guide 11 of the guide mechanism 9 is capable of descending even if there is a joint or other thick part in the passing edge 6a and the annular fabric 2, so that it can be easily passed through. In addition, the press of the separator 12 reliably prevents the edge 6a of the fabric 6 from rising, and the edge 6a
This results in smooth straightening of a and passage without stagnation. Further, according to the present invention, the cylindrical fabric 6 and the annular fabric 2 can be applied regardless of whether the material is knitted fabric or woven fabric, and whether it is stretchable or non-stretchable. Also for
By increasing the number of guide mechanisms 9 installed, it is easy to straighten them, and it can be applied regardless of the size of the curved shape.

着手段として優れたものである。 The present invention is as described above, and includes the work of straightening and sewing annular fabric to the waist and other cylindrical edges of various cylindrical fabric products such as pants (briefs), pants bottoms, panty pants, etc. It is extremely advantageous as it can be easily automated. That is, in the present invention, the cylindrical fabric 6 and the annular fabric 2 are
It is stretched on a circumferential tensioning path formed by arranging partial support members such as support rollers or support pins, and is tensioned by expanding, contracting and closing the path, so attachment and detachment operations are quick and easy. Moreover, it is easy to apply and maintain the necessary tension during sewing and straightening, and the automatic circumferential movement is smooth and light due to the small number of frictional parts. By combining the pair of movable edge guides 11 and the fixed edge guides 10 with a step and crossing them, and the separator 12 that is pressed from above, the edge 6a of the fabric 6 can be reliably straightened and curved. Regardless of the size of the shape, or even if there is a thick or thin part on the edge 6a, straightening can be achieved without any problem, and by polymerizing the annular fabric 2 through the separator 12 after straightening, it is possible to straighten both. Polymerization is carried out very accurately and without any problems such as binding, especially for fabrics such as knitted fabrics.
The smooth straightening, polymerization, and sewing can be automated, eliminating the inefficiency of conventional manual work and product variations due to individual differences in results, and making it possible to produce sewn products of uniform quality with high efficiency. Furthermore, the required equipment can be designed relatively simply and compactly, and can be easily incorporated into a conventional sewing machine, making it an excellent means for automatically sewing a circular fabric to an edge of a cylindrical fabric.

When superimposing the annular fabric on the edge of the cylindrical fabric and sewing them together, the edge of the cylindrical fabric is placed on each of the circumferential tension paths formed to be able to expand and contract freely. In addition, each of the annular fabrics is stretched separately and held in a predetermined overlapping relationship, and the edge of the cylindrical fabric is aligned along a linear guide surface formed with a step whose height is variable in a part of the path. The annular fabric is straightened and overlaid on the straightened edge via a separator that can move forward and backward placed on the same guide surface, and then passed through the sewing machine sewing section, thereby automatically straightening and overlapping the two parts. A method for sewing circular fabric, which is characterized by sewing. 2. A device for superimposing the annular fabric on the edge of the cylindrical fabric and sewing the two together, which uses a plurality of support roller groups arranged to be able to expand, contract, and close the edge of the cylindrical fabric. A circumferential tensioning path for circular fabric using a plurality of groups of support pins that can be expanded and contracted and moved forward and backward in the axial direction, similar to the circumferential tensioning path for the sewing machine, and for the edge of the cylindrical fabric in front of the sewing section of the sewing machine. A straightening means for the edge by a pair of fixed movable edge guides disposed in the circumferential tensioning path and crossing with a step, the edge guides being superimposed on the upper surface of the edge guides so as to be movable forward and backward, and supporting the annular fabric and cylindrical fabric. 1. A sewing device for annular fabric, comprising: a superposition means using a separator that presses and supports an edge.
