Description

Fiber-made surface fastener, and method and apparatus for forming ears thereof

Technical field

The present invention relates to a multi-layered structure that stands on the surface of a substrate obtained by weaving or knitting.

Male engaging element such as a hook-shaped or mushroom-shaped element, or a female engaging element composed of a number of loops alone, or the male engaging element and the female engaging element are mixed. The present invention relates to a fiber surface fastener, a method of forming ears thereof, and an apparatus for forming the same.

Background art

A surface fastener made of fiber is formed by weaving or knitting a base material, and at the same time, weaving or knitting a monofilament or a multifilament into a base material in a loop shape, and locally cutting the loop-shaped monofilament to form a hook or mushroom. A multi-filament in the form of a loop is formed by baffling or the like to disperse a loop of a single fiber so as to spread upward from the root. On the other hand, ears for sewing are formed on both side edges along the longitudinal direction of this type of hook-and-loop fastener.

A general ear is formed by forming a normal ear from a base material without weaving or knitting the monofilament or the multifilament in the ear forming regions on both side edges. For this reason, each hook-and-loop fastener tape had to be woven or knitted independently, which hindered productivity. In order to increase this productivity, when manufacturing a wide hook-and-loop fastener tape by weaving or knitting, at least one engaging element non-forming area with a predetermined width is created in the width direction, and the non-forming area is formed. To No filament or multifilament is not woven or knitted into the base material.First, an area of the base material alone is formed.

It was conceivable to cut it in 2 minutes to make an ear.

However, regardless of the width of the ears, the demand for high-mix low-volume production has increased in recent years, and the number of times that the position of the ears on the hook-and-loop fastener tapes has to be changed. When forming ears consisting of non-forming areas of engaging elements during knitting, changing the position of the ears not only takes time and effort, but also changes the design of the ears. In such a case, the preparation work is further complicated, and many changes have to be made, which lowers the productivity and is far from practical use. Ear forming technology has also been developed that can easily respond to such ear changes. For example, in Japanese Patent Application Laid-Open No. 50-144438, an electric shaved parikan is arranged for each width of a desired narrow tape in a wide-width fabric for hook-and-loop fasteners, and thereby, the surface texture is reduced. After cutting the combined element linearly in the longitudinal direction, the center is cut by a cutting cutter to produce a plurality of narrow tapes with ears. In addition, for example, Japanese Patent Publication No. 52-244252 discloses that a wide-width hook-and-loop fabric is cut to form a narrow tape, and then the engagement is provided on both side edges of each narrow tape. Cut the base of the element with a disk-shaped force-tapper that rotates around a vertical axis to manufacture a narrow-width hook-and-loop fastener tape with ears.

Also, for example, in Japanese Patent Application Laid-Open No. 62-194482, a wide fiber surface fastener having a synthetic resin coating layer formed on the back surface for preventing the engagement element from coming off projects from the surface. The engaging elements to be engaged are trimmed linearly along the longitudinal direction from the base with a grinding wheel arranged at the width interval of the narrow tape with ears to form a flat portion for forming the ear portion, and the flatness is formed. It cuts and separates from the center of the part to produce narrow tapes with ears. In addition, for example, No. 4,209,094 discloses that a surface of a wide fiber surface fastener running in a longitudinal direction on a side where an engaging element protrudes is pressed by a pressing roller having an ear forming width, and the back surface thereof is pressed. By operating an ultrasonic or high-frequency horn from the side, the engaging element pressed by the pressing roller is melted by internal heating and welded to the base material surface to form a flat surface of the ear portion.

By the way, in this type of fiber surface fastener, the male and female engaging elements formed by weaving or knitting there are two or more fibers (monofilament, multifilament). Filaments), and these fibers stand up to form loops.

Therefore, the above-mentioned Japanese Patent Application Laid-Open No. Sho 50-144 4

As disclosed in No. 52, when the engaging element on the surface fastener surface is cut off from the base with a disk-shaped cutter or an electric clipper on a plane parallel to the surface of the base material to form an ear, In particular, for engaging elements that are close to each other and that are slightly, but not exactly aligned, like regular fiber surface fasteners, the cutting edge for cutting them is one engagement. It is difficult to operate to completely cover all the fibers that make up the root of the element.

As a result, when one of the two fibers at the root of one of the loop fibers constituting the engagement element is cut, the loop fiber is not cut off while leaving the loop shape. In many cases, the protruding portion is left on the base material, and often protrudes from the side of the ear portion where the flat surface is to be formed. Due to the protruding fibers, the vertical plane formed by the engagement element row at the boundary between the ear and the unremoved engagement element does not form a substantially flat surface, which is not only unfavorable in appearance, but also subsequent sewing. It makes it difficult to achieve accurate and clean sewing in the process. In addition, it is difficult to operate the cutter blade or parikan blade on the surface of the base material, and the root of the engaging element remains in a bush shape. It tends to be protruded from the substrate surface.

On the other hand, when the engaging element is cut from the root using a grindstone as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 62-194482, the engaging element is rich in elasticity and flexibility. The cutting surface tends to be uneven, and the grinding wheel tends to be clogged with the resin used as the material of the engaging element. It was unbearable for hours of operation. Furthermore, the cut surface is heated to a high temperature by frictional heat with the rotating grindstone, and the base material surface is melt-hardened, so that the base material surface becomes hard and the flexibility as a fiber surface fastener may be lost. In this respect, even in the method of forming the ear portion disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 5-42009, the engaging element is melted by using the internal heating of the engaging element, and the surface of the base material is melted. In this case, the melted resin penetrates into the base material, and the surface of the base material becomes harder, increasing the load on the sewing needle in the subsequent sewing process.

The present invention has been made to solve such a problem, and a resin film or the like is not formed on the surface of the ear portion, so that flexibility and flatness of the ear portion formation region are ensured, and the present invention relates to the ear portion formation region. It is an object of the present invention to provide a fibrous surface fastener capable of securing the flatness of a vertical surface on a boundary line with a composite element forming region, an efficient method for forming ears of the same surface fastener, and an apparatus for forming the same. . Disclosure of the invention

The first invention in the present application relates to a surface fastener made of fiber, the basic structure of which is a fiber having a large number of male and / or female engaging elements rising from at least one surface of a base material obtained by weaving or knitting. The engaging element, which is formed in a hook-and-loop fastener made of stainless steel and has a lug extending linearly along both side edges in the width direction of the hook-and-loop fastener, is substantially flush with a part of the one surface of the base material. Characterized in that substantially no constituent fibers of the engagement element intersect with a vertical plane along the boundary between the ear portion and the non-sheared region of the engagement element. I do.

As described above, the surface fastener made of fiber obtained by weaving or knitting has a male engaging element such as a hook-shaped or mushroom-shaped monofilament on one surface of the base material. After a plurality of fiber-engaged female engaging elements composed of filaments are erected and woven in a loop shape by using a large number of them alone or in combination, the hook-shaped male engaging elements form a monofilament loop. In the mushroom-shaped male engagement element, a part is cut, and after cutting the upper end of the loop, the tip is melted to form an umbrella-shaped engagement head. The female engaging element made of a multifilament is completed by separating each constituent fiber by puffing or the like while maintaining the loop shape, and expanding the fiber in all directions.

These hook and loop fasteners are often fixed to various products such as various kinds of fabrics and various kinds of natural or synthetic leathers by sewing. Therefore, as described above, when weaving or knitting a single narrow tape, the engaging element is formed in the ear forming area on both side edges in the width direction. The ears are not woven or knitted and form ears composed only of the constituent fibers of the substrate. On the other hand, in consideration of productivity, etc., a wide surface fastener tape is woven or knitted without forming the above-mentioned ears on both side edges, and the surface fastener has a width in a width direction for commercial use. After dividing the engaging element at the boundary with a width more than twice the width of the ear, divide the ear into two. On the other hand, at the both side edges of the wide surface fastener tape, the engaging elements existing on the both side edges are simultaneously cut off with a required ear width.

SUMMARY OF THE INVENTION The present invention provides a fiber surface fan having an ear formed by cutting out a part of an engagement element. About Sunaichi. The surface fastener according to the present invention has the above-described configuration. In other words, in other words, in the ear portion formed by cutting out the engaging element from the base, in the present invention, the root of the engaging element that is cut off and left is a molten resin or a penetrating resin as in the related art. Does not exist, and the shear surface at the root is almost coplanar with the surface of the base material, and when viewed from above, it has excellent smoothness. Further, the spatial cross-sectional shape of the ear region surrounded by the engaging element and the base material has an accurate rectangular shape, and the ear is formed from the vertical wall surface formed by the engaging element group at the boundary between the ear forming region and the engaging element. Almost no constituent fiber of the engaging element protrudes toward the space above the part forming region. In other words, the engaging element has a beautiful shape in which the constituent fibers hardly protrude into the space above the ear forming area.

With such a configuration of the ear portion, when the hook-and-loop fastener of the present invention is attached and fixed to various products, the base material is solidified with a molten resin except for a back coating made to prevent the engaging element from coming off. Since there is no bent portion and there is no excess in the space above the ear forming region, and the shearing surface of the engaging element is almost flush with the surface of the base material and has smoothness. The sheared surface is glossy and the ear area is clear, so that not only can it be stably sewn, but there is no trapping such as breakage of sewing needles.

Further, in the present invention, it is preferable that the shear surface of the engagement element is formed by shearing the shear blade from the same direction. Thus, when the shearing surface of the engagement element is formed by shearing from one direction, the shearing surface does not have multidirectionality like the shearing by the conventional disk-shaped rotary blade rotating around the vertical axis. As a result, the reflected light is unidirectional, making it easy to see the ears, and it is possible to eliminate sewing errors during sewing.

This is the first shape obtained by the ear forming method of the second invention and the ear forming apparatus of the third invention described below. The basic structure of the invention according to the ear forming method is a fiber surface fastener having a large number of male and / or female engaging elements rising from at least one surface of a wide substrate obtained by weaving or knitting. A method for forming an ear portion, comprising: supplying a long surface fastener continuously along a supply path; at least one desired means for rotating around a rotation axis extending parallel and orthogonal to the supply path. Disposing a disk-shaped rotary blade having a plurality of shear blades along a width and a peripheral surface at substantially the thickness interval of the base material with the supply path; and rotating the rotary blade to perform the engagement. A method for forming ears of a surface fastener made of fiber, characterized in that a part of the element is sheared linearly in the longitudinal direction of the substrate substantially on the same plane as the surface of the substrate to form ears. It is in.

This ear portion forming method is a basic structure of the ear portion forming device for a fiber surface fastener according to the third invention, which is a male and female member standing up from at least one surface of a wide base material obtained by weaving or knitting. An ear forming device for a surface fastener made of a fiber having a large number of engaging elements of a hook or a female, comprising: a supply means for continuously feeding a long surface fastener along a supply path; It has a width and has a plurality of shearing blades along the peripheral surface, is arranged at intervals of the substrate thickness in the supply path, and rotates around a rotation axis extending parallel to and orthogonal to the supply path. This is effectively achieved by an ear forming device for a fiber surface fastener, comprising at least one disk-shaped rotary blade.

In this way, the rotating blade is rotated around the rotation axis orthogonal to the hook-and-loop fastener supply path in the transverse direction, and the engaging element present in the ear forming region of the base material is sheared from its base. The roots of the fibers constituting the engaging elements are sheared in the same direction, and at the boundary between the remaining engaging elements and the engaging elements that are not sheared at the same time, all of the engaging elements that remain without being sheared Even if the constituent fibers are not sheared and some of the loop-shaped roots are sheared and the sheared fibers are left on the substrate, a part of the root is sheared. The loop-shaped fiber projecting into the space above the ear forming region is sheared by the shearing blade at the axial end edge of the rotary blade, so that the fiber projecting into the space does not exist as a result. As a result, not only the spatial cross section of the ear portion has an accurate rectangular shape, but also high flatness and gloss are generated in the ear portion forming region as described above.

In the second invention, it is preferable that the method includes removing the sheared chips sheared by the rotary blade from the shearing region by air. As described above, by using air to remove the shear debris, the shear debris can be easily and reliably removed from the shear region. At this time, as a preferred embodiment of the third invention according to the above manufacturing apparatus, as a preferred embodiment, an air ejection means arranged on the upstream side in the supply direction of the surface fastener across the shear area of the rotary blade, and a shear area of the rotary blade And suction means disposed downstream of the hook-and-loop fastener in the supply direction with the interposed member therebetween, so that the sheared engaging element debris is blown toward the suction side beyond the periphery of the rotary blade by the air ejection means. And is reliably excluded from the shear zone. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, preferred embodiments of the present invention will be specifically described based on illustrated examples.

FIG. 1 shows a schematic configuration example of an apparatus for forming a plurality of ears in a wide and long fiber surface fastener 11.

This type of surface fastener made of fiber is used for weaving or knitting a wide tape-shaped base material and simultaneously using a large number of monofilaments or a large number of multifilaments (not shown) made of synthetic resin alone or a large number of multifilaments. Monofilaments or multiple multifilaments are mixed, and each monofilament and multifilaments are woven or knitted together by a usual method while forming a loop from the surface of the base material, and then the back surface of the base material is formed. Then, a back coating layer 12 of a synthetic resin for preventing the engagement element from being pulled out is formed, and then the monofilament loop is hooked or mushroom-shaped male engagement element, or the multifilament loop is puffed and female. It is processed into an engagement element.

This is wound up to produce a wide material roll 10 of the hook-and-loop fastener 11. The wide surface fastener 11 that is unwound from the raw roll 10 passes through the ear forming portion 13 and extends in the width direction of the engaging surface 14 formed of a number of engaging elements formed on the surface thereof. The engaging element in the ear forming area 15 having a width slightly more than twice the width of the ear on the dividing line is sheared and then wound up by the winder 16. At this time, before the wide hook-and-loop fastener 11 is wound by the winding section 16, the ear forming area 15 is cut in a width direction by a cutter (not shown) for two minutes. Alternatively, after the wide hook-and-loop fastener 11 is wound by the winding section 16, the ear forming area 15 may be divided into two in the width direction by a cutter again. .

As shown in FIG. 1, the ear forming portion 13 includes a plurality of rotating force cutters 1 arranged opposite to the hook-and-loop fastener supply path between the raw material roll 10 and the winding portion 16. It has seven. The plurality of rotary cutters 17 are fixed to a rotary shaft 18 that is arranged parallel to the surface fastener supply path and perpendicular to the transverse direction at a required interval, and is driven by a drive source (not shown). Actively rotate in one direction. Each rotary cutter 17 has a large number of saw blades 17a having a saw-like cross section formed at the same pitch on the peripheral surface thereof, and the shear width thereof is set to be more than twice as large as the ear to be formed. I have. The pitch of the plurality of cutters 17 is not limited to the same pitch but may be arbitrarily determined, but in any case, is equal to the tape width of the narrow surface fastener tape to be a product. Therefore, in the present embodiment, the rotary cutter 17 can be fixed at an arbitrary position in the axial direction of the rotary shaft 1 using, for example, a keyway and a spacer.

FIG. 2 shows a specific configuration example of the ear forming section 13. Reference numeral 19 in the drawing denotes a table constituting a supply path for the wide surface fastener 11-1 supplied from the material roll 10, and predetermined tables are provided upstream and downstream of the surface fastener supply path. They are separated and arranged on a straight line. Between the first staple 19a on the upstream side and the second table 19b on the downstream side, a number of hook-and-loop fastener supporting members 20 corresponding to the number of the rotary force meters 17 are arranged. . The distance between the hook-and-loop fastener 11 running on the upper surface of the support member 20 and the cutter blade 17a of the rotating force 17 is finely adjusted by a fine adjustment device (not shown). By the way, the gap is just the thickness of the base material 11a including the back coating layer 12 of the surface fastener 11. Is set substantially equal to

In the present embodiment, the engaging element 1 1 which is sheared from the root in the ear forming area 15 of the surface fastener 11 from the surface fastener introduction side to the discharge side periphery of the rotary cutter 17 A scattering prevention cover 21 is provided to prevent the shearing debris b from scattering around the cutter. Further, in the present embodiment, the air suction pipe 23 and the air ejection pipe are respectively opposed to the hook-in fastener inlet 22 a and the outlet 22 b of the scattering prevention cover 21 and the running hook-and-loop fastener 11. A pipe 24 is disposed, and the shavings of the engaging element 1 1b sheared by the rotary cutter 17 are discharged from the surface fastener outlet 22b by the air jetted from the air jet pipe 24. It is blown off toward the inlet 22a, and the sheared debris sent on the air is sucked by the air suction pipe 23 provided in the hook-and-loop fastener inlet 22a to the collection section (not shown). And actively carry it out.

According to the apparatus for forming ears of a fiber surface fastener according to the present embodiment configured as described above, the wide fiber surface fastener 11 delivered from the raw material roll 10 is wound in the middle of being wound. At the ears 1 1 c, a plurality of rotating forces that rotate from the downstream side to the upstream side in the traveling direction of the hook-and-loop fastener 11 1, and the base material surface of the hook-and-loop fastener 11 by the force-tutter blades 17 a The base of the engaging element lib existing in the plurality of ear forming regions 15 of the engaging surface 14 formed of a large number of engaging elements 1 1b formed on the base 11 is almost the same as the surface of the base material 11a. Shearing is performed on a plane to form ears 11 c having a flat surface without a flat engaging element in each of a plurality of ear forming areas 15 on a straight line. During the formation of the lug 11c, as described above, the shearing chips of the engagement element 11b generated by the shearing are actively discharged to the outside by using the air suction pipe 23 and the air ejection pipe 24. Is discharged.

After the ear lie is formed in this way, the wide area fastener 1 1 is wound. It is wound up positively at Toribu 16.

In this embodiment, as shown in FIG. 1, a plurality of ears 11 c are simply formed and wound on the wide surface fastener 11, but the ears 11 c are formed. After that, it is also possible to cut each ear 11c at the center in the width direction with a plurality of cutters (not shown) to continuously form the narrow width surface fastener. FIGS. 3 and 4 schematically show the shape of the periphery of the ear portion of the wide-width fiber surface fastener 11 thus obtained.

FIGS. 5 to 8 are enlarged photographs showing the configuration around the ears of the fiber surface fastener obtained by the ear forming apparatus of the present invention having the above configuration. By the way, these fiber fasteners woven a base material using a fiber yarn composed of a large number of synthetic resin fine filaments (multifilaments), and simultaneously synthesized synthetic resin thick filaments (monofilaments) or multifilaments. Wide tape was manufactured by weaving while forming a loop. Next, after a back coating is applied to the back surface of the base material, the multifilament loop is separated into constituent fiber units by puffing or the like, and the wide tape becomes a female hook-and-loop, and a monofilament loop is formed. The part is cut to form a male fastener.

Fig. 5 and Fig. 6 show a female fastener with a multifilament formed in a loop on a base material woven using a multifilament fiber yarn. Fig. 8 shows a monofilament formed into a loop on a base material woven using multifilament fiber yarns, and then a part of the monofilament was cut to form ears on a male fastener. Things.

As can be understood from these drawings, according to the above-described ear forming method and apparatus according to the present invention, unlike the conventional method, the ears 11 c are formed by the engagement elements 11 b arranged on both the left and right sides. Side wall projects into the space 25 above the ears 1 1 c. A vertical wall surface 26 where virtually no fiber is generated is formed, and the surface of the ear forming region 15 has a smooth shear surface. Therefore, the cross section of the ear 11c is formed in a very clear rectangular shape.

In other words, a part of the engaging element of the wide fiber surface fastener 11 is located at the ear 11 c formed by cutting linearly from the base, and in the present invention, it is cut by the rotary blade 17 a. At the root of the remaining engaging element 11b, there is no molten resin or penetrating resin due to internal heat generation or frictional heat of the grindstone as in the past, and the shearing surface at the root is almost flush with the base material surface. Yes, when viewed from above, it has excellent smoothness. In addition, the spatial cross-sectional shape of the ear forming area 15 surrounded by the engaging element lib of the ear 11 c formed as described above and the base material 11 a has an accurate rectangular shape, and the ear forming area The structure of the engaging element 1 1b that protrudes from the vertical wall surface 26 formed by the engaging element group at the boundary between the engaging element 11 and the engaging element 11 1b into the space 25 above the ear forming area 15 Almost no synthetic fibers are present. That is, the upper part 25 of the ear part formation region 15 has a beautiful shape in which the constituent fibers of the engagement element hardly protrude.

This is because, for example, when the root of the engagement element 11b is sheared by the rotary force cutter 17, at the boundary between the ear forming region 15 and the engagement element 11b, even if the engagement element 11b Even if a part of the constituent fiber of b protrudes from the vertical wall surface 26 formed by the engagement element group into the space 25 above the ear formation region 15, the rotating blade 17 a rotates. This is because the constituent fibers are sheared on the vertical wall surface 26. On the other hand, according to the conventional rotary blade or hair clipper rotating around the vertical axis, the root of the engaging element is simply cut off, and all the blades of the rotary blade at the root of the engaging element are cut off. In some cases, some of the loop-shaped constituent fibers are left at the root without reaching the synthetic fibers. In this case, the remaining fibers are still cut fibers The cut loop-shaped fibers remain in the state of being left on the base material, and their tips protrude and remain in the space 25 above the ear formation area 1.5. The shape of the part is ambiguous.

If the shape of the ears is not clear in this way, when the hook-and-loop fastener is sewn to various products and fixed, it is easy for the attachment wire to come off from the ears, and the appearance is also reduced.鏠 Even in terms of adhesion strength, it affects the yield as a product. Therefore, in order to perform accurate sewing at the time of sewing work, it is necessary to rely on a skilled worker having sufficient sewing techniques, which may lead to an increase in cost. '

On the other hand, the cross-sectional shape of the ear 11c formed by the above-described ear forming method and apparatus of the present invention has an accurate rectangular shape, and the ear 11c is heated by internal heating or frictional heat. Not only does the melted resin adhere to the surface of the base material 11a, or does not have a solidified part that penetrates into the base material 11a, as well as an extra space 25 above the ear forming area 15 And the shear surface of the engaging element lib is almost flush with the surface of the base material 11a and has lubricity. In order to clarify the area of the part 11c, the ear 11c is clearly distinguished from the engaging surface on which the engaging element lib is present. Even if the sewing needle does not break, the sewing will be smoother, stable work will be secured without skill, and the fatigue of sewing staff will be reduced. Sometimes high quality products can be obtained for finished products.
