Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to clothes and the like, particularly stage costumes in Japan.
In Southeast Asia and the Middle East countries, a shiny ornament or spangle (spangl) that is usually attached to a costume is used.
e) An invention of a method and an apparatus for forming continuous stitches (which are usually called "spun" in Japan in Japan) and means for attaching and sewing to clothes or the like at the same time as forming spangles, The present invention relates to a means for obtaining a chain-spangle as a material that can easily be attached and sewn.

<Prior art> Conventionally, as shown in Fig. 13, the spangle of this frequency is not continuous with a large number of spangles (03) ... A long gourd-shaped strip that is connected to, and when connecting this to clothing or the like, or when manufacturing chain spangles (03a) ……
I was trying to cut with a cutter (0a) etc. As another method, as shown in FIG. 14, a large number of unit spangles (03) punched and formed are piled up in a cylinder (0c) in a columnar shape, and when these are sewn on clothes or the like. , Or, when manufacturing the chain spangle, a thin extruding plate (0b) was used to extrude one by one from below.

<Problems to be Solved by the Invention> In the method of FIG. 13 described above, as described at the left end of FIG. 13, the spangle (03) cut and separated into the unit bodies has a connecting portion (03a) at both ends thereof. (03a) is inevitable that the quality of the remaining product is deteriorated, and in particular, the cutting position often shifts, which further tends to cause the so-called uneven quality. Further, in the method shown in FIG. 14, since the spangle itself is extremely thin, even if the machine is adjusted so that the thin extruded plate (0b) extrudes one sheet at a time, in particular, two or three sheets will be used. If the extruded plate (0b) is too thin, it may enter the layers of the spangle and cause empty extrusion, which may cause defects in the fabric pattern or toothless shapes. It had the drawback of being able to create chain spangles.

Therefore, the present invention provides a method and an apparatus capable of surely solving such conventional drawbacks.

<Means for Solving the Problems> As a technical solution, the present invention forms a unit spangle by punching and at the same time transfers it to a required position every time punching is formed, and immediately sews it onto an adherend.

There is a punch receiving blade (5a) below it, and holes (5b) for set bolts on both sides of it. A punching punch pedestal (5) having (5b) is disposed, and a set bolt hole (8e) formed in a guide pedestal (8) disposed further below. This guide base (8) bolted to (8e) has two fixed guide plates (8d) at the center. Guideway formed by (8d) (8
a) with a spangle passage cutout (8
b) is formed, and the guide pin (6
c) A slotted guide hole (8c) is formed. In the guide path (8a), two upper and lower sliding plates (6). (7) is located below the punch punch pedestal (5) and slidably arranged in the longitudinal direction thereof. The upper sliding plate (6) has a U-shaped notch (6a) on the tip side thereof, and both arm portions (6b) forming the notch (6a). (6b) is thin and has a step (6
e) has a spangle holding part (6d) forming a storage space for the cut spangle (33) on the lower surface side,
A guide pin (6c) penetrating in the vertical direction is fixed to the rear side. The lower sliding plate (7) has a U-shaped notch (7a) formed on the front end side, a long hole (7b) for inserting the guide pin (6c) at the position near the rear end side, and the rear end is It has a structure having a stopper portion (7c) bent upward in an L shape.

Thus, the upward protruding portion of the guide pin (6c) fixed to the upper sliding plate (6) is the bell crank (15).

The film tape (3) as a material for forming the spangle (33) has a tape drum suspended at a position outside the drawing on the right side in FIG. 1, and a tape guide groove (4c) under the punch blade guide hole (4a) of the fixed guide (4). ), The tape winding roll (31) is mounted on the intermittent drive shaft (30) on the left side of FIG.
It is set so as to be intermittently taken up by and the idle roll (32) provided in parallel with this. Spangle foot (2
As shown in FIG. 3, 7) has a tip portion formed in a bifurcated shape, and the spangle (3) is held in a posture in which the needle (23) is sandwiched before the sewing machine needle (23) starts to move upward.
3) It can be located above.

Next, mainly referring to FIG. 4, a spangle manufacturing and sewing method for the spangle adhered fabric (A) will be described. FIG. 4 shows main parts with the passage of time for the convenience of explaining the method.

The tape (3) is moved by the punching amount of the spangle (33) punched last time (Fig. A), and the next new spangle punching operation is started. First, the punching punch blade (12) descends until the tape (3) is punched out.
The small protrusions (12a) contacting with the spring keeps the posture in contact with the tape (3) against the pressing force of the spring (12b) (Fig. B), and the punch blade (12) further descends. At the same time as punching the spangle (33) by the cooperative action of the punch receiving blade (5) and the punch receiving blade (5a), the small projection (12a), which was resisted by the tape (3), moves to the spring (12b). The spangle (33) punched by the action is transferred onto the lower slide plate (7) located below the punch receiving table (5), and the spangle (33) is pressed (Fig. C). Next, while maintaining this posture, the upper sliding plate (6) moves forward (to the left), and the U-shaped notch (6a) at the tip avoids the small protrusion (12a) and the arms on both sides. (6b). (6b) moves onto the spangle (33) (Fig. 2). At the same time, the punch blade (12) turns to the upward movement, and the upper sliding plate (6) which advances further is the both arm portions (6b). While making contact with the step (6e) formed in the inner part of (6b), the spangle (33) is moved to the tip of the lower sliding plate (7) (Fig. E). While the sliding plate (6) is moving forward, the lower sliding plate (7), which has been prevented from moving simultaneously by the abutting action of the link (17) receiving the action of the spring (18) to the stopper portion (7c), , The contact action of the guide pin (6c) to the front end side of the long hole (7b) causes the upper slide plate (6) to move forward together with the forward movement of the upper and lower slide plates (6). The spangle (33) is held between the front ends of (7), and the spangle (33) is transferred onto the spangle passage notch (8b) formed at the front end of the guide (8) ( At the same time, the punching punch blade (12) also rises to its original position. Next, the needle (23) of the sewing machine moves downward, and these upper and lower sliding plates (6).
U-shaped notch (6a) formed at the tip of (7).
(7a) to descend, and these upper and lower sliding plates (6). (7)
When the center part of the spangle (33) held by the needle is pierced (Fig.), The upper sliding plate (6) starts to move backward, and at the same time, the lower sliding plate (7) also pulls the spring (18). Retreat by action. The needle (23) continues to descend and transfers the spangle (33) onto the spangle adhered fabric (A) (Fig. H). The needle (23) is brought into contact with the adherend material (A) and descends, and the upper thread (24) (not shown in FIG. 4) is inserted into the lower thread bobbin (29) disposed under the movable pedestal (9). ) To guide you. The bell crank (26) moves forward (to the left) from the position indicated by the chain double-dashed line in FIG. 1 to the position indicated by the solid line in almost the same manner as the lowering movement of the needle (23), and the spangle retainer (27) at the lower end thereof. Moves to the upper surface of the spangle (33) located on the adherend material (A) by the time the needle (23) reverses to the upward movement, and the spangle (33) moves with the upward movement of the needle (23). ), The upper and lower sliding plates (6). (7) retreats to the waiting posture position shown by the chain double-dashed line in FIG. In the meantime, the tape (3) is also the amount of the take-up roll (3
1) It is wound by intermittent drive (Fig.). The needle (23) rises, the spangle presser (27) retracts, the movable pedestal (9) moves to the next spangle sewing position with the material (A), and at the same time or simultaneously with these movements. The punching punch blade (12) descends and the above-described movement is repeated.

FIG. 4 used in the above description shows that the intervals between the respective members are separated from each other, particularly in the vertical direction, and that the substantially vertical sliding members (6). (7) and the guide base (8) are arranged in close contact with each other, the punching punch support (5) is arranged in close contact with the upper sliding member (6), and the tape passage (4c) is also substantially formed. It will be easy to understand the points such as the fact that it is sufficient if the tape has an interval through which the tape can easily pass. As for the motion of each part, the intermittent feeding motion of the tape (3) is the time when the punching punch blade (12) turns to the ascending motion and moves away from the lower end tape (3) of the punching blade (12) (see Fig. ) To the taper (3) of the small protrusion (12a) at the time of the next descending motion (at the time of (b)), the starting of the descending motion of the punching punch (12) can be started by the tape ( The upper and lower sliding plates (6) during the cutting action posture state (3) in 3). It is sufficient that (7) is set to the timing at which the backward movement is completed. The descending timing of the sewing machine needle (23) is also set just below the lower end (tip) of the needle immediately before contacting the spangle (33). It will be easily understood by those skilled in the art that the operations of the respective parts are carried out substantially simultaneously, such as the spangle (33) having been moved to.

Thus, both the main and sub shafts (2) shown in FIG. Main and auxiliary gears (20) mounted on (1). (10) has a diameter of 1: 2, the main shaft (2) rotates twice, the counter shaft (1) rotates once, and the sewing machine needle (23) moves up and down twice for one spangle. The case where the sewing operation is performed twice is shown. By setting in this way, as shown in FIG. 5, for the spangle adherend material (A), the sewing machine stitch is focused on the center stitch of the spangle (33) and the next stitch of the spangle center stitch. A sewing seam for the fabric (A) can be provided once between the two. In this case the spangle (33)
...... is spelled on the fabric (A) (B) at two locations before and after it.
it can.

The splicing stitching interval and stitching position of the spangle (33) to the material (A) can be arbitrarily set by the movable pedestal (9) and by extension the amount and direction of movement of the material (A). Various desired patterns can be formed on the cloth (A).

If the material (A) is not placed on the movable pedestal (9),
As shown in FIG. 6, the chain spangle (C) can be formed only by the sewing thread composed of the upper thread (24) and the lower thread (not shown). In this case, the cradle (9) does not have to be movable.

The shape of the spangle (33) is not limited to a round shape, but an elliptical shape, various square shapes, a star shape, or any other shape, depending on the shape of the punching punch blade (12) and punch receiving blade (5a). Can be

The film tape (3) is moved by the winding device (31). (3
Although the winding method is shown in 2), it can be easily understood that it may be moved by an extrusion method. Also,
One pitch for the feed amount does not mean an amount that corresponds to the punching amount of the unit spangle (33) exactly, but in short, after punching the unit spangle (33), the next unit spangle (33) is This means that the tape has to be moved by an amount suitable for punching.

The main shaft (2) and the counter shaft (1) must be rotated by changing the gear ratio (which may be chain conduction) fixed to both shafts to a positive multiple including 1: 1. You can

When the tooth ratio is 1: 1, 1: 2, 1: 3, the spangle (3
An example of the relationship between 3) and the sewing position (24a) is shown in FIG. In the figure, (24) indicates the upper thread. However, these figures are examples of the case where the material is fed straight evenly, and as described above, a complicated pattern is obtained when the material is irregularly fed non-linearly.

FIG. 7 (a) is an illustrative view of approach sewing, overlap sewing, and separation sewing when the gear ratio is 1: 1. (B) shows approach sewing, separation sewing, and 1: 2. Illustrative drawing of spangle two-point approach sewing,
(C) shows 1: 1 spangle approaching stitching at 1: 3, 1
It is an illustration figure of spangle 1 place separation sewing, and 1 spangle 2 place separation sewing.

In the embodiment shown in FIG. 8, the upper and lower sliding plates (6). (7) Another embodiment of the guide (8) is shown, in which the upper sliding plate (6) already described is a flat plate-like one having no spangle holding space on the tip lower surface side. The lower slide plate (7) has a structure in which the step upper surface (7e) is formed by thinning the upper surface side of the tip, and the spangle receiving cavity (7d) is formed. The guide base (8) has a groove formed in the central portion along the entire length in the longitudinal direction, and the upper and lower sliding plates (6). (7)
The sliding guideway (8a) is formed. The present invention may be implemented as described above.

Further, in the present invention, in the embodiment shown in FIGS. 1 to 4 and the embodiment shown in FIG. 8, the transfer plate (W) is composed of two upper and lower sliding plates (6). Although the structure constituted by (7) has been described, the transfer plate (W) does not necessarily require the upper and lower two plate bodies, and the transfer plate (W) can be constructed as in each embodiment shown in FIGS. 9 and 10. It can also be implemented by using only one plate. Thus, in the embodiment shown in FIG. 9, only the sliding plate (6) having substantially the same structure as the upper sliding plate (6) shown in FIG. The cut spangle (33) dropped directly into the guide groove (8a) of the guide base (8) with a narrow U-shaped notch (8b ') through which the spangle (33) does not pass is transferred by the step (6e). It was done like this. In this case, the chain spangle (C)
It is suitable for the production of the product and the transfer of the adhered fabric (A) to the left in FIG. 9 substantially linearly, and the spangle (33) is linearly attached and sewn on the fabric (A). . The embodiment shown in FIG. 10 is a structure in which the tip portion of the upper sliding plate (6) shown in FIG. 2 is turned upside down so that the step (6e) side is on the upper surface, in other words, The structure of the tip of the upper slide plate (6) is configured like the structure of the tip of the lower slide plate (7) in the embodiment of FIG.
e) and both arms (6b) of the U-shaped notch (6a). (6b)
A small flat cut (6f) is formed between the upper surface of the arm and the arm (6b). (6b) Hold one side of the unit spangle (33) immediately after cutting received above. However, this flat cut (6f) is not always necessary. The embodiment shown in FIG. 11 is, for example, a spangle (33).
When forming a flower pattern by, the color that forms the leaf pattern,
It is necessary to use a multi-colored tape (3) such as a color forming a petal pattern or a color forming a flower core pattern. This embodiment shows a convenient example when two or more color tapes are used in a switching manner. The tape is used for tape passage along the lower surface of the fixed guide (4) having the punch blade guide hole (4a). Tape switching rod (41) along the direction intersecting the passage (4c)
The sliding guide groove (40) is formed, and a long plate-shaped tape switching rod (41) separately formed in the guide groove (40) is internally slidably movable along the longitudinal direction. This tape switching rod (4
1) Set bolt hole (4) of the fixed guide (4)
b). Long hole (42) located below (4b) to avoid set bolt (not shown). (42) is formed (the set bolt hole (4b). The position of (4b) is the tape switching rod (41).
If they are provided outside the width of the sliding guide groove (40) that guides the long holes (42). (42) is not necessary),
This long hole (42). A plurality of guide grooves (43) for passing the tape (3) located between (42) are provided (three grooves in the embodiment diagram).
The grooves are formed in parallel, and the holes (44) for passing the punching punch blades (12) are formed on the grooves (43).

Thus, in the tape switching rod (41) shown in the embodiment, the rod member is elongated in one direction, and the extension end thereof has the knob portion (48) bent upward in an L shape. The extension part has a positioning mark (46) on the top surface of the extension part and a symbol (47) for confirming the position, and a setting ball hole (45) on the side edge part. It has a structure. The setting ball hole (45) ... is a setting ball for fixing the tape switching position located at the back of the ball retainer (4d) formed on the side of the guide groove (40) of the fixed guide (4). (Not in the figure) so that the tape switching position can be easily determined.

For this tape switching operation, a manual type is illustrated as an example of the simplest means, but it goes without saying that a switch selection type electric switching means may be used as shown in FIG. 12, for example. The switching means shown in FIG. 12 shows a state in which the driven body (a) is in the neutral position, that is, the switch (S) is in the second button position. When the switch (S) is switched to the first button position, the left coil ( l) is excited, the driven body (a) moves leftward, and when the switch (S) is switched to the third button position, the right side coil (r) is excited and the driven body (a) moves rightward. Is. The driven body (a) may be a tape switching rod (41) having the guide groove (43) shown in FIG. 11 and the punch blade passing hole (44), and the movement of the driven body (a) is controlled by the tape. It can be easily understood that the changeover rod (41) may be interlocked.

Further, when the tape switching rod is operated, it can be easily switched so that only the selected tape (3), that is, the tape (3) that is moved below the punching punch blade (12) is wound. Will be understood. This switching operation may be performed manually, but it is convenient to interlock with the operation of the tape switching rod.
