Description

  The present invention provides an elastic thread wound package having a tailing thread excellent in handleability, and more particularly, in the process of manufacturing a processed product using elastic threading, removal of the tailing yarn of the elastic thread is easy, thereby winding The present invention relates to an elastic yarn winding package that can improve the workability when switching yarns. More specifically, the present invention relates to an elastic thread winding package which is particularly effective when used in a processing apparatus for longitudinally unraveling an elastic thread called medium-large-size product among elastic threads in a winding core direction.

  Elastic yarns, in particular, polyurethane elastic yarns (sometimes referred to as polyurethane elastic fibers) are widely used as foundations, socks, pantyhose, clothing such as swimwear, and elastic functional materials in the sports field, taking advantage of their elastic properties. There is. Also, in recent years combined with non-woven fabric, it is used for stretchable members of solid gathers, waist and legs of disposable diapers, and has a wide variety of sizes and designs for adults, nursing care, children, newborns, etc. Things are sold in the world. It is also used as a sanitary napkin.

  In order to respond to such a wide variety of sizes and designs, there is a technology to change the fineness of the elastic yarn and the draw ratio of the yarn for each part, and a technology of simultaneously running several to several tens of elastic yarns simultaneously Are known.

  Patent Document 1 discloses that in recent years polyurethane elastic yarn is unwound in the axial direction of a paper tube from the needs for continuous use of a large number of polyurethane elastic yarns in paper diapers and sanitary materials applications as described above. Is becoming mainstream. In the elastic thread winding package used for such a vertical unwinding, a mouth thread (also called end thread) and a tail end thread (also called tail) are formed, in which case the tail end thread is on the paper tube used It is described that grooves (also referred to as slits) are provided in the circumferential direction outside the winding width of the elastic yarn winding body, and a yarn at the beginning of winding is introduced into the grooves. By adopting such a configuration, it is possible to tie the butt yarn with the mouth yarn of another elastic yarn winding package, and it is possible to switch the elastic yarn winding without stopping the processing, and continuously take up the warp It is possible to

  In recent years, in hygienic products typified by disposable diapers that use non-woven fabrics and elastic yarns in combination, the production volume has increased due to the increase in the population consumed, and the amount of elastic yarns used has also increased accordingly. Therefore, in the manufacturing process of such a product, improvement of the ease of taking out the butt yarn from the elastic yarn wound body package is required.

  At present, in general, the rear end yarn is unwound from the paper tube groove after manufacturing the elastic yarn winding body package, cut into an adequate length necessary for binding with the mouth yarn, or prepared after winding the elastic yarn, A method in which a butt yarn is wound around a paper tube groove and used by a person or a mechanical device at the time of processing is the mainstream.

  In the case where the above-mentioned elastic yarn wound package is manufactured and then the rear end yarn is taken out, when shipping to a processing place of a product for sanitary material application represented by a paper diaper etc. Since the butt yarn is damaged by abrasion etc. and causes a thread breakage problem in warping and unwinding in a processing place, an elastic yarn wound package having a form in which the butt yarn is wound around a paper tube groove is preferred. In this case, when shipping to a processing site, damage received during transportation can be avoided, but at the processing site, an operation of taking out the butt yarn from the elastic thread winding body package, that is, a person can take out the butt yarn bundle from the paper tube groove It takes time and effort, such as finding the place, picking it out by hand, and adjusting it to the length of the butt yarn required to tie it to the mouth thread. In particular, when manually pulling out the rear end yarn from the paper tube groove, the elastic yarn having stretchability is difficult to take out because it is biting into the paper tube groove, and it takes time. Therefore, the improvement of the visibility of the take-out point of the rear end yarn at the processing site and the facilitation of the pick-out have been problems.

  Since the paper tube groove is provided on the entire circumference of the paper tube as in Patent Document 2 in order to improve the removal of the rear end yarn, a place where the grooved portion is partially removed is provided, and the elasticity wound there is provided. Although a device such as checking the position of the rear end of the yarn with the eyes of a processing operator and picking it out by hand is disclosed, the entire circumference of the paper tube of the elastic yarn winding body package is confirmed and that portion It was necessary to find out, and the problem of visibility remained.

  The present invention is equipped with a butt yarn on a cored core paper tube, and it is possible to easily visually recognize the taking-out position of the butt yarn, and to surely take out the butt yarn using a hand or a jig. In addition, it is possible to prevent the rear end yarn portion from collapsing during case packing and transportation.

It is a schematic diagram which shows the condition which withdraws a tail yarn by the linear thing clamped by the tail yarn of the elastic thread-wound thread package of this invention. It is a schematic diagram which shows the condition which withdraws a tail yarn by the tape-like material pinched by the tail yarn of the elastic thread-winding package of this invention. It is a schematic diagram which shows the condition which pulls out the tail yarn used by the comparative example. It is a schematic diagram which shows the elastic thread winding body package used by Example 1-2 and Comparative Examples 1-2. FIG. 3 is an enlarged view of a rear end yarn portion of FIG. FIG. 10 is a schematic view showing an elastic thread winding body package used in Example 3. It is a schematic diagram which shows the whole of a paper tube and the elastic thread-wound body package of this invention. It is a schematic diagram which shows the example of the elastic thread winding body package in which the tag was attached to the linear thing.

  The present invention is an elastic yarn winding package comprising a paper tube and an elastic yarn winding body, wherein the paper tube is perpendicular to the paper tube axis between the end of the elastic yarn winding body and the end of the paper tube. The elastic has a groove in the circumferential direction, and the rear end thread of the elastic yarn winding body is wound around the groove, and at least a part of the thread bundle of the rear end thread is crossed and a linear material or a tape-like material is held. It is a thread winding body package.

  In the present invention, the elastic yarn winding body refers to a winding of an elastic yarn in a cheese shape, and a winding of an elastic yarn winding body on a paper tube is referred to as an elastic yarn winding body package. In the present invention, the paper tube has a groove in the circumferential direction orthogonal to the paper tube axis between the end of the elastic yarn winding body and the end of the paper tube, and the end yarn of the elastic yarn winding body is in the groove It is wrapped. That is, as shown in FIG. 5, in the elastic thread winding body package of the present invention, at least one of the portions where the paper tube 7 is exposed from the elastic thread winding body 9 has a groove 8 for winding the tail 2. , An elastic thread to be the rear end thread 2 is wound there. And a linear thing or a tape-like thing is pinched | intersecting crossing at least one part of the yarn bundle of the said tail yarn. By using such a configuration, when used in the processing apparatus, it is possible to easily pull out the rear end yarn 2 from the elastic thread winding body package by pinching and pulling the wire or tape which is being held. As a result, the rear end yarn 2 can be tied to the mouth thread 10 of the elastic yarn winding body package to be used next, and the elastic yarn winding body can be smoothly switched without stopping the processing. In addition, the definition of a linear thing or a tape-like thing is mentioned later.

  The shape of the paper tube used for the elastic yarn winding body package of the present invention is not particularly limited, but a cylindrical shape is generally used. A colored paper is attached to the surface of the paper tube, and further, a cellophane film containing regenerated cellulose as a main component, a moistureproof cellophane film, a polyester film, or the like attached on colored paper, or a coating resin agent containing polyvinyl alcohol as a main component Or what coated the corresponding thing on colored paper is used. In addition, although the colored paper itself is attached, and the colored paper which is subjected to the concavo-convex processing, embossing, etc. is used, the present invention is effective in the difference in the material of the paper tube and the surface agent and the processing method of the surface. There is no loss of

  Between the end of the elastic yarn winding body and the end of the paper tube, at least the winding width around which the elastic yarn is wound in the paper tube axial direction, ie, the exposed side of the paper tube in the elastic yarn winding body package By having the tail end thread winding groove in the portion which becomes, it becomes possible to draw out the unwinding part at the time of elastic thread winding object formation as a tail end thread.

  Generally, the exposed portion of the paper tube in the elastic yarn wound package is preferably 5 to 10% of each end of the both ends, assuming that the paper tube length is 100%. The exposed portion of the paper tube in an elastic yarn winding package having a net weight of 4.5 kg of a general elastic yarn is 8 to 15 mm. At least one of them has a groove for fixing the tail yarn. In addition, when the tail yarn winding groove is only in the vicinity of one end, there is a problem as a package in which the elastic yarn winding body is disposed such that the length of the exposed portion of the paper tube on the groove side is longer than the other There is no.

  The above-mentioned bottom thread winding groove indicates a groove provided in the winding direction, that is, in the direction perpendicular to the paper tube axis. Further, although the groove is in the circumferential direction orthogonal to the paper tube axis, it may exist over the entire circumference, or there may be a portion where the groove is interrupted in a part of the circumferential direction. When the tailing thread winding groove is not on the entire circumference, assuming that the entire circumference of the paper tube is 100%, the ratio of the length without the tailing thread winding groove is about 3 to 10%, more preferably about 4 to 8% It is preferable in that the tail yarn can be reliably gripped in the rear yarn winding groove at the time of winding.

  The method for forming the rear end thread winding groove in the paper tube is not particularly limited, for example, a method of forming a continuous recess by pressing, a method of making a cut with a blade, etc. The method is preferred. The reason is that the groove shape can be changed according to the shape of the rotary blade, the depth and width of the groove can be freely changed according to the pressing method, and a complex cross-sectional shape can be obtained by combining and using rotary blades of different shapes. And the like can be formed. Further, since the groove is provided by such processing, the cross-sectional shape of the tail yarn winding groove is generally V-shaped or substantially V-shaped, or a shape similar thereto.

  The shape (change in groove width) and cross-sectional shape in the surface of the paper tube of the rear end yarn winding groove consider the formation of the rear end yarn, that is, the efficiency surface at the time of winding, the fineness of elastic thread, elastic modulus, etc. It should be set. For example, in order to make it easy for the tail yarn to be wound around the paper tube, even if a groove width of a part of the tail yarn winding groove is wider and deeper than that of the other portion is provided as an introduction groove. Good. It is preferable that the depth of the introduction groove is generally shallower than that of the other end yarn winding groove. There may be a plurality of such introduction grooves in the circumferential direction of the groove.

  When an elastic yarn is wound around a paper tube to form an elastic yarn wound package, first, the elastic yarn is wound around a rear end yarn winding groove provided on the paper tube, and then an elastic yarn wound body portion is formed. It is a yarn package. The tailing yarn is wound while being bitten into the groove on the paper tube and becomes a bundle of yarn in the groove.

  The length of the rear end yarn of the elastic yarn winding package is not particularly limited and may be set appropriately according to the mechanism of the winding machine for winding up the elastic yarn, etc., but usually the rear end yarn winding groove of the paper tube The number of turns is preferably two or more, and more preferably five or more. There is no particular upper limit on the number of turns of the paper tube in the tail yarn winding groove, but it is often sufficient if it is wound 10 times, and it is preferable to wind the tail yarn so that it does not protrude from the groove.

  In the present invention, a wire (1 in FIG. 1A) or a tape (3 in FIG. 1B) crossing at least a part of the yarn bundle of the yarn is wound around the yarn winding groove of the paper tube It is held by a yarn bundle (5 of FIG. 3) of yarn. At least a portion indicates about 2 to 10%, preferably about 5 to 90%, with respect to the number of winding rounds of the tail yarn. Crossing means that the linear material or the tape-like material crosses the groove direction of the tail yarn, that is, the winding direction of the rear yarn (A in FIG. 3).

  The linear material or the tape-like material is a linear material having a short side / long side of 0.7 or more and 1 or less in the case of drawing a rectangle of the smallest area circumscribed about the cross section of the portion intersecting with the tail yarn The tape-shaped material has a short side / long side of 0.01 or more and less than 0.7.

  The material of the linear or tape-like material may be a material such as a paper string or cotton thread, a plastic resin such as nylon or polyester, or a combination thereof, or one reinforced with a wire or the like. It is not limited to The back thread of the elastic yarn is stretched at the time of winding, and it is necessary to cross it with the back thread which is tightly wound like a rubber, so it has a certain balance of rigidity and flexibility. And those made of nylon or polyester resin are more preferable.

  Particularly preferred is one molded on a linear or tape form based on a nylon resin or polyester resin, and if it is linear, the cross section is round and the diameter is about 0.2 to 1.0 mm. In the case of a tape shape, one having a tape thickness of 1.0 mm or less and a tape width of about 2.0 to 4.0 mm is preferable.

  The linear material or tape-like material of the present invention preferably has, in addition to crossing with the tail yarn, the linear material or the tape-like material being annular and loosely binding the yarn bundle of the tail yarn. The term "annular" means that the whole is looped and that it is partially looped. The loose binding means that the yarn bundle is not tightened with the wire or tape (4 in FIG. 1C, FIG. 2-4), that is, in the ring (ring) formed by the wire or tape. Indicate that the buttocks can move freely. In normal bundling, that is, when the tail yarn is completely squeezed so that the bundle does not collapse, when the tail yarn is pulled out from the elastic thread winding body package using the wire or tape of the present invention, the tail yarn (L in FIGS. 1A-1B) can not be freely changed.

  As a representative example of a specific linear material, resin molding typified by “loop lock (registered trademark)” thread lock, “chain lock (registered trademark)”, loose tie, tag made of nylon or polyester, etc. It is an article, one end has a pointed end, and it has a key on its end for the purpose of preventing it from falling off, and the other end becomes an insertion slot for fixing, and has a function to prevent the opening A commercially available product can be used, and one having appropriate changes in thickness, loop length and the like can be used. These are preferable because they form a loop-like ring (ring) easily and are processed so as to fix both ends of the wire, so that the tail yarn can be loosely tied. Moreover, in order to cross with a part of the yarn bundle of the tail yarn on the paper tube, the one having a sharp tip is preferable.

  In addition, it may be a nylon monofilament thread used for fishing, etc., a cotton thread, a hand-made thread or sewing thread made by combining synthetic fibers with natural fibers such as cotton and hemp, etc. As it is necessary, it is preferable to use a resin molded product which can easily fix the above-mentioned both ends.

  As a representative example of a specific tape-like product, it is a resin molded product representing nylon or polyester, which is also called a binding band, cable tie, "insrock (registered trademark)", etc., and commercially available products may be used. Yes, and you can use linear, loop length, etc., as appropriate. These are preferable because they can easily form a loop ring and the size of the loop can be freely changed. Further, it is preferable that the width of the tape is narrow and the tip of either one is sharp since it crosses a part of the yarn bundle of the tail yarn on the paper tube.

  By installing the linear or tape-like material as described above in a state where it crosses at least a part of the yarn bundle of the tail yarn, they serve as a mark as the take-out position of the tail yarn, and the visibility is greatly improved. It will be In addition, when they form a loop, they can be easily pulled out even when taken out by hand, and in some cases, they can be hooked using an L-shaped hook jig or the like. By these, it is possible to automate the work of picking up the buttocks (work of picking up the buttocks) using an apparatus or machine.

  Further, by setting the length of the loop of the linear material or the tape-like material to be larger than the entire circumference of the paper tube, the paper tube can be installed in the loop (FIG. 4). Then, when the elastic thread winding body package is packaged in a case and shipped to a processing site, it is possible to avoid an accident such as the rear end thread coming off due to an accidental accident such as contact with the packing material. The loop length in such a case is preferably 1.1 to 1.5 times the diameter of the paper tube. If it is less than 1.1 times, the workability in placing the paper tube in the loop is reduced, and if it is more than 1.5 times, the paper tube tends to come out of the loop.

  In addition, it is said that the linear material or the tape-like material has flexibility, that is, the form of the loop is deformed into any shape according to the size and shape of the suction port of a mechanical device such as an air ejector or suction suction device. It means to do. The flexible linear or tape-like material enables suction of the tail yarn bundle and can be easily removed from the elastic yarn wound package.

  Moreover, it is preferable that at least one tag is attached to the elastic thread winding body package of the present invention by a linear material or a tape-like material. Here, a tag is a tag attached in order to attach the information regarding a to-be-attached body.

  The size and shape of the tag are not particularly limited, but if it is too large, the possibility of deformation such as wrinkles or bending or breakage is relatively large, and if too small, sufficient visibility and information can be covered Problems such as inability to occur may occur. From this point of view, the size and shape of the display surface is preferably in the range of 10 to 80 mm. As for the shape, if the corner is erected, the elastic thread on the surface of the elastic thread winding body package may be damaged. In the case of a polygonal shape, the connecting portion of each side has a vertex and does not have an R and It is preferable to do.

  The thickness of the tag is not particularly limited, but if it is too thin, the possibility of damage such as deformation or breakage is relatively large, and if it is thick, the direction is relatively difficult to be deformed and visibility is improved. It may hurt you. From this point of view, the thickness is preferably in the range of 0.05 to 0.5 mm.

  The material of the tag is not particularly limited, but may be appropriately selected from the viewpoint of deformability and printing for information display. From the viewpoint of deformability, if it is too soft, visibility and readability of information may be reduced due to deformation, and if it is too hard, the elastic yarn wound package may be damaged. From the viewpoint of printability, it is preferable to use a resin film coated with paper, a coating for printing, or the like, or a film obtained by laminating them.

  The method of attaching the tag is not particularly limited as long as it does not inadvertently come off the wire or the tape, and (i) integrated with the wire or the tape, (ii) the wire or the tape The tag may be fixed by attaching to the elastic material, or (iii) the linear material or the tape material may be passed through the hole or cylindrical part formed in the tag, and the tag may be movably attached. . FIG. 6 shows an example of the elastic yarn wound body package to which the tag 11 attached to the linear object and the tag 11 are attached by the method of (iii) described above. FIG. 6-1 is an example in which a part of the tag is folded back to form a tubular portion, and the tag is attached through a linear object. A pressure-sensitive adhesive may be used to fix the folded portion, and heat fusion, use of a stapler, and the like are not particularly limited. Further, the linear material may be movably attached to the cylindrical portion, or the tag may be movably attached without fixing the linear material and the tag. FIG. 6-2 is an example in which the tag of FIG. 6-1 is provided with a perforation 12 for cutting so that the tag can be cut off when using the elastic thread winding package. FIG. 6-3 is an example of passing a line through one hole provided in the tag. FIG. 6-4 is an example of passing a line through two holes provided in the tag. By changing the size of the provided holes, the tag can be loosely fixed to the wire. FIG. 6-5 is an example in which a part of the tag is folded back to form a tubular portion, and a linear object is passed.

  Attaching the tag facilitates identification of the elastic thread winding package. For example, in a processing field where plural types of elastic yarn winding packages are simultaneously used and bonded to a non-woven fabric, it is important to identify the elastic yarn winding packages in order to obtain a predetermined product. It is useful from the viewpoint of working efficiency and product yield that identification of the elastic thread winding body package is easy in such a situation.

  By adding information identifying the elastic thread winding body package by the color and shape of the tag and / or the characters, numbers, symbols, etc. displayed on the tag, compared with the conventional case, the elastic thread winding body package Identification is very easy. That is, the information conventionally used for identification is affixed to the product display label affixed on the product case in which the elastic thread winding package is packaged, or to the inside of a paper tube which is a part of the elastic thread winding package. Although it is difficult to identify individual packages from the outside, it is necessary to look into the inside of the paper tube even after being taken out of the box due to the tag attachment. Because there is no In the past, in order to make it easy to identify the type of elastic yarn, the elastic yarn manufacturer sometimes responded such as changing the color of the paper tube, but by attaching a tag as described above, paper The time and effort required to change the tube color is reduced, and paper tube procurement is simplified.

  The information displayed on the tag can be converted to barcode or converted two-dimensional pattern information as digital information aggregated into one-dimensional pattern information as well as information that can be read directly by people such as characters, numbers, and symbols. A two-dimensional code such as “registered trademark” may be written together. When digital information is used in this manner, it is also preferable to include information on traceability such as the production time and place of the elastic thread winding body package. In addition, a registered trademark or a logo of the elastic yarn wound package may be described. Based on the information on the tag, the user using the elastic thread winding package can use the information to correctly identify, and the information on the tag tells the elastic yarn manufacturer side about defects such as thread breakage at the time of processing. It is also easier to request improvement.

  The elastic yarn used in the present invention is not particularly limited, but polyurethane elastic fiber or polyurethane elastic yarn is mentioned as a preferred example. The elastic yarn is a multifilament composed of a plurality of single yarns, and is usually an elastic yarn of 20 filaments to 120 filaments. The fineness of the elastic yarn is not particularly limited, but it is preferable to apply to an elastic yarn of a fineness of 150 to 1,300 decitex called medium-thick fineness product. Moreover, the cross section of the filament may be an aggregate in which those forms are combined, such as round cross section, oval, peanut shape, and wedge shape.
