Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quilting processing method using an adhesive.

[0002]

2. Description of the Related Art When manufacturing a quilted product having an intermediate layer of a cushion material such as urethane, sponge, synthetic cotton, or palm rock between cloth, leather, artificial leather, and the like,
conventionally,

As shown in FIG. 1, the original fabric layer 6 is sewn from the front and back with a sewing machine, the upper thread 4 and the lower thread 5 are entangled to form a recess 7, and the quilting process is performed by repeating this process. That method was common.

However, in this method, tension is always applied to the sutures 4 and 5 due to the restoring force of the cushion material of the intermediate layer 1, so that the yarns 4 and 5 are easily stressed and frayed. . Therefore, in order to prevent the threads 4 and 5 from fraying, a rubber-based adhesive is applied to the end of the sewing, or the sewing is started or the end of the sewing is removed.

Although measures such as re-sewing as in a and b of FIG. 2 have been taken, all of them require time and effort, and even if these measures are taken, the frays of the threads 4 and 5 are completely removed. There was something far from preventing.

[0004] For example, an automobile seat is also a kind of quilted product formed by a method of sewing with a thread, but it is known that a defective product due to a thread break occurs soon after shipment. The reason for this is that, due to the sewing operation of the sewing machine, the
This is because three to four of the sewing threads twisted in the book may be cut. In this case, even though it seems that there is no problem in appearance, it is actually the rest of the two or three threads that are repeatedly subjected to the restoring force of the cushioning material and the load of the driving person, It is easy to cut, and it is hard to find at the time of sewing, and it often breaks after shipping or during use.

[0005]

Therefore, thread breakage, which has been used in the conventional quilting manufacturing method by sewing using a thread, is completely prevented, and the thread is simple, has high durability, and uses a thread. It is an object of the present invention to provide a new quilting processing method having various development possibilities that were not possible with the processing method.

[0006]

Means for Solving the Problems The present invention has been made to solve the above problems, and the gist of the invention is as follows.

In FIG. 3, in a layer 6 of an original fabric for quilting processing with an intermediate layer 1 of a cushion material interposed therebetween,
Alternatively, the adhesive 8 is injected from the front surface, the injection point is compressed, and ultrasonic or high-frequency current is applied to cure the adhesive 8, and the surface layer 2, the intermediate layer 1, and the back surface layer 3 are bonded to each other to be integrated. The present invention relates to the provision of a quilting processing method using an adhesive 8, characterized in that the quilting is formed by forming the concave portion 7 by repeating this process discontinuously or continuously. .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment using the processing method of the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 4 is a right side view (partial sectional view) of one embodiment using the processing method of the present invention.

In FIG. 4, a layer 6 of original fabric is stretched on a mounting frame 9, the mounting frame 9 is fixed to an arm 10, and the movement of the arm 10 is controlled by a control panel 11. Further, the mounting frame 9 is placed on the surface plate 12, and can freely move in any horizontal direction on the surface plate 12 in conjunction with the movement of the arm 10. Further, the base 12 is fixed to the base 20 by support legs 17.

A hole 19 is formed substantially at the center of the surface plate 12, and a tip 23 of the adhesive injector 13 is inserted into the hole 19 from below. An adhesive bottle 14 is connected below the adhesive injector 13, and a lower portion of the adhesive bottle 14 is fixed by a bottle fixing device 18. Adhesive injector 1
3 is capable of vertical movement.

Above the adhesive injector 13 is a layer 6 of original fabric.
The ultrasonic bonding device 15 is installed so as to share the central axis A with the adhesive injection device 13. Ultrasonic bonding machine 1
5 is loosely fitted to the adhesive fixing device 21 so that it can move up and down. The adhesive fixing device 21 is fixed to the arm 16, and the arm 16 is fixed to the base 20.

The operating state in the embodiment is as follows:

FIG.

FIG.

FIG. 7, and

FIG. 8 will be described. The adhesive injector 13 rises along the hole 19 formed in the surface plate 12, and the tip 23 of the original material layer 6 extends from the back surface of the material layer 6 stretched over the surface plate 12.
Then, a hole is made in the back layer 3 to reach the intermediate layer 1 and stopped once at that position to inject the adhesive 8. The adhesive 8 is in the form of a fine powder or a liquid.

When the injection of the adhesive 8 is completed, the adhesive injector 13 descends and comes out of the original fabric layer 6. At the same time when the lowering of the adhesive injector 13 is completed, the lower base 27 moves to the left,
The ultrasonic bonding machine 15 descends, and the tip 22 compresses the entire fabric layer 6. When the compression is completed, the ultrasonic bonding device 15 stops at that position, and supplies ultrasonic waves from the tip 22. The emitted ultrasonic waves harden the adhesive 8 instantaneously,
The surface layer 2, the intermediate layer 1, and the back layer 3 are adhered to each other to form the recess 7. When the ultrasonic bonding machine 15 moves up, the lower table 27 moves and restores to the right of the original position.

One step is completed by the above process.

FIG. 7 shows the completion of the dot-like quilting process.
Information of completion of one process is sent to the control panel 11, and the control panel 11 moves the arm 10 in accordance with data input in advance. The mounting frame 9 fixed to the arm 10 also moves in conjunction with the arm 10, and the original fabric layer 6

As shown in FIG. 8, after moving by the moving distance B, the central axis A is located at a new position of the original fabric layer 6, and the next step is started.

By arbitrarily setting the moving distance B,
Point-like quilting at arbitrary intervals is possible.
Further, if the moving distance B is set to a small value, the portion to be bonded by the adhesive 8 will be continuous, and the concave portion 7 will be formed in a linear shape, and a linear quilting process will be possible.

The mounting frame 9 is freely movable on the surface plate 12 in any horizontal direction, and its moving distance and direction are controlled by a control panel 11 via an arm 10. Therefore, according to the data input in advance, the layer 6 of the original cloth may be dotted or linear,
It is possible to form the accumulation of the concave portions 7 in any form. For example, if illustrations, patterns, characters, and the like are input to the control panel 11, the corresponding illustrations, patterns, characters, and the like can be formed. A quilted product drawn by stacking can be manufactured.

When a colored adhesive is used,

As shown in FIG. 9, the original fabric layer 6 is placed upside down, and the adhesive 8 is injected from the surface layer 2 side. The reason is that the color tends to appear on the side where the tip 23 of the adhesive injector 13 is inserted.

Alternatively,

FIG. 10; and

As shown in FIG. 11, an adhesive injector 13 is also attached to the upper arm 16 together with the ultrasonic adhesive 15, and after the adhesive 8 is injected, the original fabric layer 6 is moved in the direction of C, and the ultrasonic bonding is performed. Vessel 1
5 and the ultrasonic wave is applied, and the adhesive 8
Is cured to form the recess 7.

When a colored adhesive is used,

As shown in FIG. 12, after the adhesive 8 is injected into the intermediate layer 1, the injection is continued while pulling up the tip 23 of the adhesive injector 13 so that the adhesive 8 appears only slightly on the surface. . By doing so, the color of the adhesive 8 is
It can be more clearly represented on the surface. Also in this case, it is obvious that this operation can be performed from below by turning the original fabric layer 6 upside down.

Also,

As shown in FIG. 13, by changing the shape of the tip 22 of the ultrasonic bonding device 15 into various shapes, the shape of the compressed concave portion 7 can be made to match the shape of the tip 22.
The finished product can have various varieties.

Also,

As shown in FIG. 14, the bottle fixing device 24 has a large circular shape, and a large number of adhesive bottles of different colors are attached thereto, and the bottle fixing device 24 is rotated around the central axis of the bottle fixing device 18 (direction E).
If possible, by bringing a bottle of a required color under the hole 19, the color of the formed concave portion 7 can be changed, and the accumulation of the multicolor concave portions 7 can be formed. This large bottle fixing device 24 is attached to the arm 16,

FIG.

It is also possible to inject the adhesive of each color from above as in the method seen in FIG.

Further, this large bottle fixing device 24 is

FIG. 15 shows a square shape, or

It is also possible to form a straight line as shown in FIG.

In the case of FIG. 15, the adhesive bottle 14 of each color is selected by reciprocating the rectangular bottle fixing device 25 in the F direction and the G direction.

[0022]

The method of processing quilting using the adhesive of the present invention has the above-described structure and operation, and as a result, brings about the following effects.

Since no yarn is used unlike the conventional quilting process, there is no risk of breakage due to yarn breakage, and a quilted product having much higher durability can be manufactured. It is expected that the occurrence of defective products will be drastically reduced compared to conventional processing methods, and it will be possible to supply more stable products to purchasers or users even after shipping or use, and quilting products Has the potential to be a processing method that will make a big epoch in the market.

In the conventional quilting process, a rubber-based adhesive is applied to the end of the sewing to prevent the sewing thread from fraying, or the sewing start and the sewing end are performed.

FIG. 2 shows a case where sewing was performed as in FIGS. 2A and 2B, but both required a great deal of labor and labor, and a complete effect could not be expected. However, by using the quilting processing method of the present invention, all the labor and labor required to prevent the yarn from being frayed in the conventional processing method become unnecessary, and a significant speedup and rationalization of the entire process can be expected. .

In the conventional quilting method,
Due to the problem of the resistance of the thread to be sewn as described above, the cushion material of the mid layer 1 could not be made too thick. However, in the quilting method of the present invention, by increasing the injection amount of the adhesive 8, it is possible to apply the quilting process even to a layer of the original cloth having a thickness impossible by the conventional processing method. It has become possible.

For example, it is possible to combine four or more layers of various cushioning materials as the intermediate layer 1.
For example, by combining various cushioning materials such as a combination of urethane and palm rock, a combination of urethanes having different specific gravities, and a combination of urethane and synthetic cotton, the performance of the finished product can be improved or By selecting and combining suitable cushioning materials, for example, a more comfortable ride can be brought in the case of an automobile seat, or a richer living life can be realized by using it for furniture or interior materials.

By coloring the adhesive, a quilted product having a colored concave portion can be manufactured.

FIG. 13 is a major feature of the quilting method of the present invention that a concave portion with a pattern can be formed by performing the processing as shown in FIG. As a result, the possibility of developing the quilted product on the design side can be made much richer.

Further,

As shown in the embodiment of FIG. 4, if a device capable of freely horizontally moving the original fabric layer 6 temporarily attached to the mounting frame 9 by the control panel 11 is used, a straight line, Curves, geometric patterns,
Characters, illustrations, various patterns, family crests, caricatures,
Any and all patterns such as manga, trademarks, marks, copy-forgery-inhibited patterns, etc. can be drawn by the locus of the bonding points. By arbitrarily combining this method with the above-mentioned colored adhesive and an ultrasonic bonding machine with a processed tip, it is possible to produce a quilted product that could not be considered at all with the conventional processing method. In today's market for rich fashion, it is possible to create endless new products.

As just one example of a quilted product by the processing method of the present invention,

FIG. 17 shows an automobile seat as shown in FIG.

FIG. 18 shows a seat cover as shown in FIG. In each case, the illustration is performed by the locus of the point of the adhesive using the apparatus described in the embodiment. In addition to this, furniture products such as child seats and their seat covers, reception sets and their seat covers,
It can be applied to all fields that human life covers, such as bed covers, interior supplies and interior materials, clothes, bags, shoes, stationery, and interior materials for trains, ships, aircraft and spaceships.
