Description

The present invention relates to a method for attaching a slide fastener that is sewn and that attaches the slide fastener to a cloth of clothing made of synthetic fibers or the like.

  As is well known, the slide fastener has a large number of service teeth arranged on a pair of tape members sewn on the edges of the fabric to be attached that face each other. A configuration in which the engagement teeth are engaged and disengaged is common.

  In recent years, from the viewpoint of labor saving, etc., it has been carried out by using a laser processing machine to form the edge of the fabric to which the slide fastener is to be attached, and was made from a synthetic fiber made of a thermoplastic synthetic resin. A cloth, a thermoplastic synthetic resin tape in close contact with the back surface of the cloth, and a linear cut portion formed by penetrating the cloth and the synthetic resin tape with a laser beam; A zipper tape of a slide fastener is attached facing the cut portion, and a melt-solidification formed on the edge portion of the cut portion of the fabric by solidifying after the synthetic resin tape and the fabric are melted by laser light A slide fastener mounting structure (for example, characterized in that the melt-solidified portion of the synthetic resin tape protrudes slightly from the melt-solidified portion of the fabric. , See Patent Document 1.) It is known.

Japanese Patent No. 3467494

  However, even in the above configuration, since the final attachment of the fabric and the slide fastener is eventually performed by sewing, the two tape members in the slide fastener are respectively the right attachment target fabric and the left attachment target fabric. If the fabric to be attached becomes very bulky at the time of welding, and the fabric to be installed on the right side and the fabric to be installed on the left side must be kept from shifting. In this case, the deviation must be corrected, and the work is very laborious. In addition, the risk of mixing broken needles and the like is extremely high, and although inspection using a meter-reading machine is performed, it is a problem from the viewpoint of safety.

  Furthermore, when the synthetic resin tape is configured to be attached to the fabric to be attached by heat press, the welded portion of the fabric is solidified by heat and the flexibility is impaired, and irregular undulations occur in the fabric to be attached itself. There was a drawback that the appearance was very bad.

  Further, the fabric to be attached at the periphery of the slide fastener is not preferable for the wearer because it is felt as a tightness at the periphery of the fastener, resulting in a decrease in product quality.

  In addition, the fabric is flat when the slide fastener is not attached, but when the slide fastener is sewn to the fabric, the dentition of the slide fastener is covered with the fabric, so that unevenness is likely to be formed on the fabric, and the fabric is sewn. There is a drawback that it takes time and effort to form the line accurately and in good shape.

  Furthermore, in order to prevent the tooth from biting the dough, the synthetic resin tape must have a structure in which the melted and solidified portion protrudes from the melted and solidified portion of the dough. was there.

  On the other hand, knitted fabrics and stretchable fabrics are generally weak against heat and are not suitable for performing heat press etc., so slide fasteners are intended for such knitted fabrics and stretchable fabrics. If it can be attached, a slide fastener can be used in an unprecedented field, which is very preferable.

The present invention has been made in view of the above circumstances, and even if the fabric is not only a fabric but also a knitted fabric or an elastic fabric, it does not require sewing and can be easily manufactured. It also solves the problem of providing a slide fastener mounting method that does not cause the fabric to be attached to the periphery of the fastener to be flexible, ensures flexibility, does not lead to the mixing of broken needles, has a good appearance, and has a beautiful appearance. It should be a challenge.

A slide fastener mounting hole is provided in the fabric to be attached and the thermal bonding member, and a curved or linear welding line or a plurality of points are formed on the overlapping portion where the tape member of the slide fastener and the fabric to be mounted overlap with the thermal bonding member interposed therebetween. The welding point to be shaped is continuously formed in the longitudinal direction of the slide fastener by a welding means using a pressure roller and an ultrasonic horn, and the portion other than the welding line or the welding point is left as a non-welded portion in the overlapping portion. In the slide fastener mounting method for welding, the pressure roller for mounting the slide fastener having a substantially H-shaped cross section in front view that constitutes the welding means has a rotating shaft portion in a direction perpendicular to the longitudinal direction of the slide fastener, and has a small diameter portion and a small diameter portion. Convex part that is adjacent to the left and right of the part, has a larger diameter than the small diameter part, and forms the shape of the welding line or welding point A pressurizing part that superimposes the fabric to be attached and the thermal adhesive member, melts the fabric to be attached and the thermal adhesive member with a laser or ultrasonic wave from the thermal adhesive member side, Forming a slide fastener attachment slot or slide fastener attachment notch having a width larger than the width of the row portion, and temporarily attaching the attachment object fabric and the thermal adhesive member by heat generated by the laser or ultrasonic fusing In the state temporarily fixed in step 2, a slide fastener having a dentition portion in which a large number of dentitions are arranged on a pair of tape members is slid from the thermal adhesive member side. Superimpose so that it fits within the fastener mounting slot or slide fastener mounting notch, with the slider operating surface side of the slide fastener facing upward and engaging the engagement teeth. Is placed so that the pressure part contacts the overlapping parts on the left and right sides of the slide fastener, and the small diameter part does not contact the upper part of the dentition part of the slide fastener, and the width of the small diameter part In the state where it is approximately the same as the width dimension of the dentition row in the state where the dentition is engaged, it is sequentially fed between the horn and the pressure roller for attaching the slide fastener, and sandwiched and welded, and the left and right sides of the slide fastener are The above-mentioned problem is solved by a slide fastener attaching method characterized by welding continuously at the same time.

According to the invention according to claim 1 of the present invention, a piece of fabric to be attached made of thermoplastic fibers and a thermal bonding member are polymerized, and the above-mentioned fabric to be mounted and heat are heated by laser or ultrasonic waves from the thermal bonding member side. By fusing the bonding member, the heat bonding member is melted by the heat generated by laser or ultrasonic fusing. Particularly, the fabric to be attached and the heat bonding member, which are not suitable for conventional welding, such as knitted fabrics and stretchable fabrics. Can be temporarily fixed at the temporary fixing portion, and can be attached on average without causing wrinkles or distortion at the overlap portion of the slide fastener.

In addition, by forming a slide fastener mounting oblong hole having a width larger than that of the slide fastener, which will be described later, the slide fastener is attached to the thermal fastener member so that the service teeth of the slide fastener can be accommodated in the slide fastener mounting hole. Polymerization from the side, forming a linear or linear welding line or a plurality of dot-like welding points continuously in the longitudinal direction of the slide fastener by ultrasonic welding means, and the welding line or welding point Even if it is a fabric that is not suitable for welding, such as knitted fabric and stretchable fabric, it can be attached to the fabric to be installed without sewing by using a mounting method that leaves a non-welded part larger than the welded area. Because it can reduce the manufacturing cost and does not sew. Re it is possible to eliminate the risk of needle contamination.

Furthermore, since the small diameter portion does not contact the upper portion of the dentition portion of the slide fastener, the width dimension of the small diameter portion and the width dimension of the engagement dentition portion engaged in the slide fastener are substantially the same, so the welding is performed. At this time, the engagement tooth row in the engaged state is guided by the pressure portion of the pressure roller for attaching the slide fastener, and the slide fastener can be arranged straight with respect to the delivery direction. Thereby, it is possible to prevent the welding point from shifting, the fabric from shifting, and the wrinkles, and the slide fastener can be attached to the mounting target fabric very well.
In addition, since the pressure parts on both the left and right sides of the slide fastener are welded continuously and continuously through the small diameter part, various conditions such as the left and right rotational speed and the pressing force at the pressure part are determined at the left and right positions of the slide fastener. Since the slide fastener can be welded under the same conditions, the occurrence of wrinkles due to bias can be prevented, and the slide fastener can be welded in a balanced state.

  A slot for attaching the slide fastener is formed on the fabric to be attached and the thermal adhesive member with laser or ultrasonic waves, and the slide fastener is inserted from the thermal adhesive member side so that the engagement tooth fits in the slot for attaching the slide fastener. It can be easily manufactured without sewing, by forming a welding line and / or a plurality of welding points with ultrasonic welding means from the fabric side to be attached, and leaving a non-welded part in part. The purpose of this fabric was to keep the fabric soft, look good and have a beautiful appearance.

(Mounting structure according to Embodiment 1 of the present invention)
As shown in FIGS. 1 and 2, the mounting structure according to the first embodiment of the present invention is a set of two to one mounting target fabric 2 made of polyester fabric and having stretch properties. This is a mounting structure in which a slide fastener 1 having a service tooth row portion 10 formed by engaging a number of service teeth on a tape member 11 is attached.

  Here, the width dimension w2 (the book) larger than the width dimension w1 (about 3.5 millimeters in the present embodiment) of the dentition portion 10 connected to and connected to the attachment object fabric 2 and the hot melt adhesive film 3a. In the embodiment, an elongated hole 20 for attaching a slide fastener (about 6 mm) is formed.

  The edge portion 25 of the slide fastener mounting slot 20 is cut so as to form a plane-view wave pattern, and in the slide fastener mounting slot 20, the dentition part 10 is provided. It is exposed without contacting the edge 25 of the long hole 20 for attaching the slide fastener.

  The hot-melt adhesive film 3a uses an ultra-thin polyurethane film, the front side is in contact with the fabric to be attached 2 and partially welded, and the back side is in contact with the tape member 11 of the slide fastener 1 and partially It is provided by welding. Thereby, the tape member 11 of the slide fastener 1 and the attachment target fabric 2 are attached via the hot melt adhesive film 3a.

  Moreover, the fabric 2 to be attached has a structure in which a plurality of dot-like welding points 21 and continuous welding lines 22 are formed in a pattern on the overlapping portion 23 along the edge of the slide fastener attaching elongated hole 20. A structure in which the hot melt adhesive film 3 a is melted and solidified at a plurality of welding points 21 to attach the attachment target fabric 2 and the tape member 11, and a portion other than the welding points 21 in the overlapping portion is left as a non-welding portion 24. It has become.

  Furthermore, the upper and lower ends of the fabric 2 to be attached and the upper and lower ends of the slide fastener 1 are melted, so that the service teeth 27 of the slide fastener 1 at the melted location are deformed by melting and fixing, and the slider S is prevented from being removed. It is assumed that the above configuration is provided.

  The tape member 11 in the slide fastener 1 in the first embodiment uses a coarse cloth, and when the hot melt adhesive film 3a is melted by the configuration, the hot melt adhesive film 3a enters the coarse cloth. As the contact area with the fabric increases, the binding property of the hot melt adhesive film 3a increases, and the durability of the slide fastener 1 improves.

  Further, as shown in FIG. 1, the slider S of the slide fastener 1 has a width dimension smaller than the width dimension w2 of the slide fastener mounting long hole.

(Attaching method according to Embodiment 2 of the present invention)
Next, the attachment method of the slide fastener 1 which concerns on Example 2 of this invention is demonstrated. A mounting method for forming a mounting structure substantially equivalent to the mounting structure according to the first embodiment except that the pattern has a weld line, the edge shape of the slot for mounting the slide fastener, and the shape of the slider S are different. is there. Of course, the present invention is not limited to the first embodiment and the second embodiment.

First, the method of attaching the slide fastener according to the second embodiment of the present invention is as follows. The hot melt adhesive film 3a is overlaid on the material 2 to be attached as shown in FIGS. Fusing with a CO ₂ gas laser (a fusing line 50 is shown in FIG. 5), as shown in FIG. 4, a long hole 20 for attaching a slide fastener that connects the hot melt adhesive film 3a and the material 2 to be attached is formed. The shape of the edge part 26 of the long hole 20 for attaching the slide fastener is formed as a straight line.

  Then, as shown in the lower figure of FIG. 5, the hot melt adhesive film 3a is attached only in the vicinity of the edge portion 26 of the slide fastener attaching long hole 20 by heat generated when the slide fastener attaching long hole 20 is formed. A temporary fixing portion 28 welded to the target fabric 1 is formed and temporarily fixed.

  Next, the slide fastener 1 is attached to the slide fastener attachment slot 20 using an ultrasonic welding machine. As shown in FIG. 6, the ultrasonic welding machine is configured to perform the ultrasonic welding by performing sandwiching of a horn 41 that vibrates up and down and a pressing roller 40 for attaching a slide fastener that rotates while pressing downward from above. The fabric 2 to be attached is sequentially sent out by the rotation based on the horizontal central axis of the pressure roller 40 for attaching the fastener and the rotation of the horn 41 in the circumferential direction of the vertical axis.

  As shown in FIG. 7, the slide fastener mounting pressure roller 40 includes a small diameter portion 45 at the longitudinal center position, a pressure portion 42 adjacent to the left and right of the small diameter portion 45 and having a larger diameter than the small diameter portion 45, 42 and rotating shaft portions 46 and 46 provided adjacent to the right and left outer sides of the pressurizing portions 42 and 42 are integrally provided.

Here, the height dimension of the step formed by the small diameter part and the pressure part is formed larger than the height dimension of the dentition part 10 of the slide fastener. The pressurizing portions 42, 42 are continuously formed with a convex portion 44 for forming a welding point over the entire circumference.
Further, the width dimension w3 of the gap 43 between the pressurizing sections 42 and 42 and the width dimension w1 of the combined tooth arrangement section 10 are formed to be approximately the same.

  That is, the continuous configuration of the small-diameter portion 45 and the pressurizing portions 42 and 42 has a substantially H-shaped cross section when viewed from the front, and the small-diameter portion does not contact the upper portion of the dentition portion 10 of the slide fastener 1. 10 will be straddled.

  As the slide fastener mounting pressure roller 40 rotates, a welding line and a welding point are formed simultaneously and continuously on the left and right sides of the slide fastener.

  In order to attach the attachment target fabric 2 and the slide fastener 1 according to the second embodiment, the attachment target fabric 2 to which the hot melt adhesive film 3a is attached is turned upside down, that is, the hot melt adhesive film 3a. Is placed below the hot melt adhesive film 3a with the operation surface side of the slider S facing upward and the engagement teeth engaged, and an ultrasonic welder. Placed on the horn 41.

  As described above, since the width dimension of the engagement tooth of the slide fastener combined with the width dimension of the slide fastener attachment hole is smaller, the engagement tooth row portion 10 of the slide fastener 1 is fitted in the slide fastener attachment long hole 20. The tape member 11 comes into contact with the hot melt adhesive film 3a.

  In this state, the material is sandwiched and welded between the horn 41 and the slide fastener mounting pressure roller 40 in order from the end of the attachment object fabric 2 and the slide fastener 1 and sent out in the longitudinal direction of the slide fastener.

At this time, as described above, the pressure roller 40 for attaching the slide fastener has the width dimension w3 of the gap between the pressure portions 42 and 42 and the width dimension w1 of the combined service tooth substantially equal. Therefore, in the welding process, the combined tooth arrangement part 10 is guided to the pressure part 42 of the pressure roller 40 for attaching the slide fastener, and the slide fastener 1 is arranged straight with respect to the delivery direction. Therefore, it is possible to prevent the displacement of the welding point, the displacement of the attachment target fabric 2 and the wrinkle, and the slide fastener 1 can be attached to the attachment target fabric 2 with a very good appearance.

  And after the welding process by an ultrasonic wave is complete | finished, the upper end and lower end of the slide fastener 1 are fuse | melted with the laser processing machine with the upper end and lower end of the fabric 2 to be attached (laser fusing line 51 is shown in FIG. 8). As shown in FIG. 9, due to the melting of the slide fastener 1, the service teeth 27 of the slide fastener 1 in the melted portion are in a melt-fixed state and function as a retaining mechanism for the slider S.

The stretched polyester knitted fabric is easily cut by heat. For example, it is very difficult to realize the attachment mode according to the present invention by a normal cutting method such as ultrasonic cutting, but CO _2. By using the gas laser, it is possible to form the slide fastener attaching long hole 20 and to attach the slide fastener 1 even in a knitted fabric or stretchable fabric.

  In addition, as shown in FIG. 11, the slide fastener mounting structure according to the third embodiment of the present invention has a slide fastener mounting notch 29 that opens to the upper end side instead of the slide fastener mounting long hole 20 in the first embodiment. Formed. A slide fastener having a slider retaining body formed in advance on the upper end side is used. Note that the retaining member in the third embodiment is made of metal.

  The slide fastener mounting method for realizing the slide fastener mounting structure according to the third embodiment basically performs the same steps as the method disclosed in the second embodiment. The cut-out portion for attaching the slide fastener is formed by fusing the hot melt adhesive film 3a which is the attachment object fabric 2 and the thermal adhesive member 3 polymerized with each other with a laser.

  Due to the fusing, the edges of the fabric 2 to be attached are reinforced by the welding and solidification of the heat-welding member, so that the opposing edges do not spread greatly in the subsequent step of attaching the fastener, and good workability is achieved. Can be secured.

  In the said Example 1 thru | or Example 3, the hot-melt-adhesive film 3a is used as the heat-adhesive member 3, The thin-film thing which consists of a polyurethane as this hot-melt-adhesive film 3 is equipped with the softness | flexibility especially, and is preferable. However, in the present invention, the present invention is not limited to this, and a general hot melt adhesive film 3 such as polyamide or polyester can be used. It is also possible to use a powder or the like.

  Moreover, in the present invention, it is excellent in that it can be used for the attachment object fabric 2 having stretchability, but including non-stretch attachment object fabrics (fabrics, etc.) including natural fibers that have been used in the past, It can be used in the configuration according to the present invention.

  Furthermore, in the said Example 1, 2, although both the upper end part and the lower end part of the slide fastener 1 were cut out with cloth, this invention is not restricted to this, According to the attachment position and use of the slide fastener 1 Thus, only the upper end portion or the lower end portion can be melted, or both the upper end portion and the lower end portion can be melted together with the attachment target fabric 2.

  Further, in the present invention, the service tooth row portion 10 refers to a case where the service teeth are arranged in a row, and a protrusion formed in parallel with the service teeth in the vicinity of the service teeth by arranging the service teeth. This is intended to include any case where a portion including a ridge 12 is shown. For example, the case shown in FIG. 2 shows a case where the dentition part 10 includes a collar 12, and the slide fastener according to another embodiment shown in FIG. The case where 10 is formed is shown.

  According to the pressure roller 40 for attaching the slide fastener disclosed in the present invention, the slide fastener placed on the horn, which is the ultrasonic oscillation transmission means, and the material to be attached are pressurized, so that the engagement tooth of the slide fastener is obtained. The slide fastener and the fabric welding means are equipped with a horn which is an ultrasonic oscillation transmission means and a slide fastener. A clamping structure having a rotation axis in a direction perpendicular to the longitudinal direction and forming the shape of the welding line or the welding point is realized.

  Then, the overlapping portions on the left and right sides of the slide fastener are straddled across the dentition part 10 so that the pressure part 42 of the pressure roller 40 for attaching the slide fastener does not contact the dentition part 10 of the slide fastener 1. The two tape members 11 and the cloth to be attached 2 that are parallel to each other through the dentition portion 10 are attached to the tape member 11 with good appearance without causing deviation, wrinkles, and undulations. The target fabric 2 can be attached.

At this time, the width dimension w3 of the gap between the pressure portions 42, 42 in the pressure roller 40 for attaching the slide fastener is substantially the same as the width dimension w1 of the engaged tooth row portion in the slide fastener. The combined tooth arrangement portion 10 is guided to the pressure portion 42 of the pressure roller 40 for attaching the slide fastener at the time of welding, and the slide fastener 1 is arranged straight with respect to the delivery direction. Furthermore, it is possible to ensure that there is no deviation of the welding point, fabric deviation, or wrinkle, and if the welding line and the welding point are continuous patterns, it is a high decorative pattern. Can be added quickly and accurately.

  Further, in the present embodiment, both the slide fastener mounting slot 20 and the slide fastener mounting notch 29 both use a laser fusing that allows complex processing and can reduce the processing work itself. The invention is not limited to this, and the long hole for attaching the slide fastener or the notch for attaching the slide fastener can be formed by ultrasonic instead of the laser.
