Description

INDUSTRIAL APPLICABILITY According to the present invention, it is easy to take out the tail yarn of the elastic yarn in the manufacturing process of the elastic yarn winding body package having the tail yarn with excellent handleability, specifically, the processed product using the elastic yarn as a material, thereby winding. The present invention relates to an elastic yarn winding body package that can improve workability when switching yarn bodies. More specifically, the present invention relates to an elastic thread winding body package, which is particularly effective when used in a processing device for vertically removing and unwinding an elastic thread called a medium-thick fineness product among elastic threads.

Elastic yarns, especially polyurethane elastic yarns (sometimes referred to as polyurethane elastic fibers), are often used as elastic functional materials in the fields of clothing such as foundations, socks, pantyhose, swimwear, and sports, taking advantage of their elastic properties. There is. Also, in recent years, by combining with non-woven fabric, it has been used for the three-dimensional gather part of disposable diapers, the elastic member of the waist part and the leg part, and it has a wide variety of sizes and designs for adults, nursing care, children, newborns, etc. Things are on sale in the world. It is also used for menstrual napkins.

In order to accommodate such a wide variety of sizes and designs, technologies such as changing the fineness of elastic threads and the draw ratio of threads for each part, and running several to dozens of elastic threads in parallel and bonding them to non-woven fabric at the same time are available. Are known.

According to Patent Document 1, in recent years, polyurethane elastic threads have been unwound in the axial direction of paper tubes because of the need to continuously use a large number of polyurethane elastic threads in the above-mentioned disposable diapers and sanitary material applications. Is becoming mainstream. In the elastic thread winding body package used for such vertical unwinding, a mouth thread (also called an end thread) and a tail thread (also called a tail) are formed, and the tail thread is on the paper tube used at that time. It is described that a groove (also referred to as a slit) is provided outside the winding width of the elastic yarn winding body in the circumferential direction, and the yarn at the beginning of winding is introduced into the groove to form the elastic yarn. With such a configuration, the tail thread can be tied to the mouth thread of another elastic thread winding body package, the elastic thread winding body can be switched without stopping the processing, and the vertical unwinding can be performed continuously. Can be done.

In recent years, in sanitary material products such as paper diapers that use a combination of non-woven fabric and elastic thread, the production volume has increased due to the increase in the consuming population, and the amount of elastic thread used has also increased accordingly. Therefore, in the manufacturing process of such products, it is required to improve the ease of taking out the tail yarn from the elastic yarn winding body package.

Currently, in general, the tail thread is formed by unwinding the elastic thread winding body package from the paper tube groove after manufacturing and cutting it to a length sufficient to be tied to the mouth thread, or even after the elastic thread is wound. The mainstream method is to wrap the tail thread around a paper tube groove and untie it with a human or mechanical device during processing.

In the case where the tail thread is taken out after manufacturing the above-mentioned elastic thread winding body package, contact with the packing material and vibration during transportation when shipping to the processing plant of products for sanitary materials such as paper diapers. The elastic yarn winding body package in which the tail yarn is wound around the paper tube groove is preferred because the tail yarn is damaged by rubbing or the like and causes a thread breakage problem in the vertical unwinding at the processing plant. In this case, when shipping to the processing plant, it is possible to avoid damage during transportation, but at the processing plant, the work of taking out the tail yarn from the elastic yarn winding body package, that is, a person can take out the tail yarn bundle from the paper tube groove. It is necessary to find a place, pick it up by hand, and adjust the length of the buttock thread required to tie it to the mouth thread, which requires time and effort. In particular, when the tail thread is manually taken out from the paper tube groove, the elastic thread having elasticity is difficult to take out because it bites into the paper tube groove, and it takes time. Therefore, it has been a problem to improve the visibility of the place where the tail thread is taken out in the processing plant and to facilitate the picking up.

In order to improve the take-out of the tail thread, as in Patent Document 2, since the paper tube groove is provided on the entire circumference of the paper tube, a place where the groove cutting portion is partially eliminated is provided, and the elasticity wound around the paper tube groove is provided. Although the device such as checking the position of the tail thread of the thread with the eyes of the processing worker, pinching it by hand, and taking it out is disclosed, check the entire circumference of the paper tube of the elastic thread winding body package and check that part. It had to be sought out, leaving visibility issues.

Japanese Unexamined Patent Publication No. 2000-289931 Japanese Unexamined Patent Publication No. 2014-105103

The problem to be solved by the present invention is that the take-out position of the tail thread can be more easily visually recognized even in a paper tube having no grooved portion as in Patent Document 2, and the position of taking out the tail thread can be visually recognized more easily by using a hand or a jig. It is also an object of the present invention to provide an elastic yarn winding body package that can take out the tail yarn of a length necessary for surely binding to the mouth yarn, and as a result, can further reduce the work load.

The present invention employs any of the following means in order to solve the above-mentioned problems.

(5) The elastic spool body package according to any one of (1) to (4) above, to which at least one tag is attached by the linear or tape-like material.

In the present invention, the tail thread is provided on the core paper tube, the position where the tail thread is taken out can be easily visually recognized, and the tail thread can be reliably taken out by hand or a jig. In addition, it is possible to prevent the tail thread portion from collapsing even during case packing and transportation.

It is a schematic diagram which shows the situation which pulls out the tail thread by the linear thing sandwiched between the tail thread of the elastic thread winding body package of this invention. It is a schematic diagram which shows the situation which pulls out the tail thread by the tape-like material sandwiched between the tail thread of the elastic thread winding body package of this invention. It is a schematic diagram which shows the situation which pulls out the tail thread used in the comparative example. It is a schematic diagram which shows the elastic thread wound body package used in Examples 1 and 2 and Comparative Examples 1 and 2. It is an enlarged view of the tail thread part of FIG. 2-2. It is a schematic diagram which shows the elastic thread winding body package used in Example 3. It is a schematic diagram which shows the whole of the paper tube and the elastic thread winding body package of this invention. It is a schematic diagram which shows the example of the elastic thread winding body package which attached the tag to the linear object.

The present invention is an elastic thread winding body package composed of a paper tube and an elastic thread winding body, and the paper tube is orthogonal to the paper tube axis between the end of the elastic thread winding body and the end of the paper tube. It has a groove in the circumferential direction, and the tail thread of the elastic thread winding body is wound around the groove, and the elastic thread or tape-like object is sandwiched by intersecting with at least a part of the thread bundle of the tail thread. It is a thread winding thread body package.

In the present invention, the elastic thread winding body refers to a product in which an elastic thread is wound into a cheese shape, and a product in which an elastic thread winding body is wound on a paper tube is referred to as an elastic thread 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 thread winding body and the end of the paper tube, and the tail thread of the elastic thread winding body is formed in the groove. It's wrapped around. That is, as shown in FIG. 5, the elastic thread winding body package of the present invention has a groove 8 for winding the tail thread 2 on at least one of the portions where the paper tube 7 is exposed from the elastic thread winding body 9. , An elastic thread serving as a tail thread 2 is wound around the elastic thread. Then, a linear object or a tape-like object is sandwiched so as to intersect with at least a part of the thread bundle of the tail thread. With such a configuration, the tail thread 2 can be easily pulled out from the elastic thread winding body package by pinching and pulling the sandwiched linear object or tape-like object when it is used in the processing apparatus. As a result, the tail thread 2 can be tied to the mouth thread 10 of the elastic thread winding body package to be used next, and the elastic thread winding body can be smoothly switched without stopping the processing. The definition of linear or tape-like material will be described later.

The shape of the paper tube used in the elastic thread winding body package of the present invention is not particularly limited, but a cylindrical shape is generally used. Colored paper is attached to the surface of the paper tube, and cellophane film containing recycled cellulose as the main component, moisture-proof cellophane film, polyester film, etc. are attached onto the colored paper, and a coating resin agent containing polyvinyl alcohol as the main component. Alternatively, a corresponding material coated on colored paper is used. Further, those to which colored paper itself is attached and those to which uneven processing, embossing, etc. are applied to colored paper are also used, but the present invention has an effect of the invention in the difference in the material of the paper tube, the surface agent, and the surface processing method. Is not impaired.

Between the end of the elastic yarn winding body and the end of the paper tube, at least the end side in the direction of the paper tube axis with respect to the winding width around which the elastic thread is wound, that is, the exposed portion of the paper tube in the elastic thread winding body package. By having the tail thread winding groove in the portion to be, the unwound portion at the time of forming the elastic thread winding body can be pulled out as the tail thread.

Generally, the exposed portion of the paper tube in the elastic spool body package is preferably 5 to 10% at each end, assuming that the paper tube length is 100%. The exposed portion of the paper tube in the elastic thread winding body package having a net weight of 4.5 kg of a general elastic thread is 8 to 15 mm, respectively. At least one of them has a groove for fixing the tail thread. If the tail thread winding groove is located only near one end, there is a problem even if the elastic thread winding body is arranged so that the length of the exposed portion of the paper tube on the grooved side is longer than the other. There is no.

The tail 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 perpendicular 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 tail thread winding groove is not provided on the entire circumference, the ratio of the length without the tail thread winding groove is 3 to 10%, more preferably about 4 to 8%, assuming that the entire circumference of the paper tube is 100%. , It is preferable in that the tail thread can be reliably gripped in the tail thread winding groove at the time of winding.

The method of forming the tail bobbin winding groove on the paper tube is not particularly limited, such as a method of forming a continuous dent by pressurization and a method of making a notch with a blade, but the method of making a notch by pressing a rotary blade is pressed. The method is preferred. The reasons are that the groove shape can be changed by the shape of the rotary blade, the depth and width of the groove can be freely changed by the pressing method, and the complicated cross-sectional shape can be obtained by using the rotary blades of different shapes in combination. It is possible to form a groove of the blade. Further, since the groove is provided by such processing, the cross-sectional shape of the tail bobbin winding groove is generally a V shape, a substantially V shape, or a shape similar to the V shape.

The in-plane shape (change in groove width) and cross-sectional shape of the tail thread winding groove should be determined in consideration of the formation of the tail thread, that is, the efficiency of winding, the fineness of the elastic thread, and the elastic modulus. Just set it. For example, in order to make it easier for the tail thread to wrap around the paper tube, a groove having a part of the tail thread winding groove wider than the groove of the other part and having a deeply cut shape may be provided as an introduction groove. good. It is preferable that the depth of the introduction groove is generally shallower than that of the other tail thread winding grooves. There may be a plurality of such introduction grooves in the circumferential direction of the groove.

When the elastic thread is wound around the paper tube to form the elastic thread winding body package, the elastic thread is first wound around the tail thread winding groove provided on the paper tube, and then the elastic thread winding body portion is formed to form the elastic thread winding. It is a thread package. The tail thread is wound while biting into the groove on the paper tube, forming a thread bundle in the groove.

The length of the tail thread of the elastic thread winding body package is not particularly limited, and may be appropriately set by the mechanism of the winder for winding the elastic thread, but usually, the tail thread winding groove of the paper tube is used. It is preferable that the spool is wound twice or more, and more preferably five or more times. There is no particular upper limit to the number of times the paper tube is wound around the tail thread winding groove, but it is often sufficient to wind the paper tube 10 times, and it is preferable to wind the paper tube to such an extent that the tail thread does not protrude from the groove.

In the present invention, a linear object (1 in FIG. 1A) or a tape-like object (3 in FIG. 1B) intersecting at least a part of the thread bundle of the tail thread is wound around the tail thread winding groove of the paper tube. It is sandwiched by a bundle of threads (5 in FIG. 3). At least a part indicates that it is about 20 to 100%, preferably about 50 to 90%, with respect to the number of winding turns of the tail thread. Crossing means that the linear or tape-like objects intersect with respect to the groove direction of the tail thread, that is, the winding direction of the tail thread (A in FIG. 3).

A linear object or a tape-like object is a linear object whose short side / long side is 0.7 or more and 1 or less when a rectangle with the minimum circumscribed area is drawn for the cross section of the portion intersecting the tail thread. The tape-like material has a short side / long side of 0.01 or more and less than 0.7.

Typical examples of linear or tape-like materials include materials such as paper strings and cotton threads, plastic resins such as nylon and polyester, combinations thereof, and materials reinforced with wires. Not limited to. The tail thread of the elastic thread winding body is stretched during winding and needs to be crossed with the tail thread that is wound like rubber, so it has a certain balance of rigidity and flexibility. , Nylon or polyester resin is more preferable.

Particularly preferable is one molded in a linear or tape form based on a nylon resin or a polyester resin, and if it is linear, the cross section is round and the diameter is about 0.2 to 1.0 mm. The tape shape is preferably 1.0 mm or less, and the tape width is preferably 2.0 to 4.0 mm.

In the linear or tape-like material of the present invention, in addition to intersecting the tail thread, the linear or tape-like material is annular, and it is preferable that the thread bundle of the tail thread is loosely bound. The term "annular" means that the whole is looped and the part is partially looped. Loose binding is not a state in which the yarn bundle is tightened with a linear or tape-like material (4 in FIG. 1C, FIG. 2-4), that is, in a ring formed by the linear or tape-like material. Indicates that the tail thread is freely movable. When the normal binding, that is, the tail yarn is completely squeezed so that the bundle does not collapse, the tail yarn is pulled out from the elastic yarn winding body package using the linear or tape-like material of the present invention. This is because the length (L in FIGS. 1A to 1B) cannot be freely changed.

Typical examples of specific linear objects are "loop lock (registered trademark)" thread locks, "chain locks (registered trademark)", loose ties, resin moldings such as those made of nylon or polyester, which are also called tag fasteners. It is a product, one tip is sharp, and the tip is equipped with (has) a key for the purpose of preventing it from coming off, and the other tip serves as an insertion port for fixing and has a function to prevent it from coming off. It is possible to use a commercially available product, and a product in which the thickness, loop length, etc. are appropriately changed can be used. These are suitable because a loop-shaped ring is easily formed and processed so as to fix both ends of the linear object, so that the tail yarn can be easily loosely bound. Further, since it intersects with a part of the thread bundle of the tail thread on the paper tube, a thread having a sharp tip is preferable.

Nylon monofilament threads used for fishing, cotton threads, handicraft threads made by combining natural fibers such as cotton and linen with synthetic fibers, and sewing threads may be used, but both ends are tied when forming a loop. Since it is necessary, it is preferable to use the above-mentioned resin molded product which can be easily fixed at both ends.

Specific examples of tape-shaped products include binding bands, cable ties, and resin molded products such as nylon or polyester, which are also called "insulok (registered trademark)", and commercially available products can be used. You can use the one with the linearity, loop length, etc. changed as appropriate. These are suitable because a loop-shaped ring can be easily formed and the size of the loop can be freely changed. Further, since it intersects with a part of the thread bundle of the tail thread on the paper tube, it is preferable that the tape width is narrow and one of the tips is sharp.

By installing a linear or tape-like object as described above in a state where it intersects with at least a part of the thread bundle of the tail thread, they serve as a mark as a position for taking out the tail thread, and the visibility is greatly improved. Will be. Further, by forming a loop, they can be easily picked up even when they are taken out by hand, and in some cases, they can be hooked by using an L-shaped hook jig or the like. With these, the work of taking out the tail thread (the work of taking out the tail thread) can be automated by using a device or a machine.

Further, by making the loop length of the linear or tape-shaped object larger than the entire circumference of the paper tube, the paper tube can be installed in a state where the paper tube is arranged in the loop (FIG. 4). By doing so, when the elastic yarn winding body package is packed in a case and shipped to the processing plant, it is possible to avoid an accident such as the tail yarn coming off due to an unexpected accident such as contact with the packing material. In such a case, the loop length is preferably 1.1 to 1.5 times the diameter of the paper tube. If it is less than 1.1 times, the workability when arranging the paper tube in the loop is lowered, and if it exceeds 1.5 times, the paper tube tends to come off the loop.

In addition, the linear or tape-like material has flexibility, that is, the shape of the loop is deformed to an arbitrary shape according to the size and shape of the suction port of a mechanical device such as an air ejector or a suction suction device. Means to do. The flexible linear or tape-like material allows the tail thread bundle to be sucked and can be easily taken out from the elastic thread winding body package.

Further, it is preferable that at least one tag is attached to the elastic thread winding body package of the present invention by a linear object or a tape-like object. Here, the tag is a tag attached to attach information about the 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 and bending, and damage such as tearing will be relatively large, and if it is too small, the visibility and amount of information will be sufficiently covered. Problems such as not being able 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 square. As for the shape, if the corners are raised, the elastic yarn on the surface of the elastic thread winding body package may be damaged. Therefore, in the case of a polygonal shape, the connecting portion of each side does not have an apex and has an R. It is preferable to do so.

The thickness of the tag is not particularly limited, but if it is too thin, the possibility of deformation or tearing is relatively high, and if it is thick, the direction is relatively difficult to deform and visibility is improved, but the elastic thread winding body package. May hurt. From this point of view, the range is preferably 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 displaying information. From the viewpoint of deformability, if it is too soft, the visibility and information readability may be deteriorated due to the deformation, and if it is too hard, the elastic bobbin winder package may be damaged. From the viewpoint of printability, paper, a resin film coated with a coating for printing, or a resin film obtained by laminating them is preferable.

The method of attaching the tag is not particularly limited as long as it does not inadvertently come off from the linear or tape-like object, and is (i) integrated with the linear or tape-like object, and (ii) the linear or tape-like object. Either method may be adopted, such as fixing to a shape, or (iii) attaching a linear or tape-like material through a hole or tubular part formed in the tag so that the tag can be moved. .. FIG. 6 shows an example of a tag 11 attached to a linear object by the method of (iii) described above and an elastic spool package to which the tag 11 is attached. FIG. 6-1 is an example in which a part of the tag is folded and pasted together to form a cylindrical portion, and the tag is attached through a linear object. An adhesive may be used for fixing the folded portion, and the heat fusion, the use of a stapler, or the like is not particularly limited. Further, the linear object may be movably attached to the cylindrical portion, or the tag may be movably attached without fixing the linear object 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 when the elastic thread winding body package is used. FIG. 6-3 is an example in which a linear object is passed through one hole provided in the tag. FIG. 6-4 is an example in which a linear object is passed through two holes provided in the tag. By changing the size of the provided hole, the tag can be loosely fixed to the linear object. FIG. 6-5 is an example in which a part of the tag is folded back to form a cylindrical portion and a linear object is passed through.

Attaching the tag facilitates the identification of the elastic bobbin body package. For example, in a processing plant where multiple types of elastic yarn winding body packages are used at the same time and bonded to a non-woven fabric, it is important to identify the elastic yarn winding body packages in order to obtain a predetermined product. It is useful from the viewpoint of work efficiency and product yield that the elastic yarn winding body package can be easily identified in such a situation.

By adding information that identifies the elastic yarn winding body package by the color and shape of the tag and / or the letters, numbers, symbols, etc. displayed on the tag, the elastic yarn winding body package can be compared with the conventional one. It will be very easy to identify. That is, the information used for identification in the past is affixed to the product label affixed on the product case in which the elastic thread winding body package was packed, or to the inside of the paper tube which is a part of the elastic thread winding body package. It was difficult to identify individual packages from the outside due to the attached product label, etc., but it is necessary to look inside the paper tube even after taking it out of the box due to the tag attached. Because there is no such thing. In the past, in order to facilitate the identification of the type of elastic thread, the elastic thread manufacturer sometimes took measures such as changing the color of the paper tube, but by attaching a tag as described above, the paper The time and effort to change the tube color is reduced, and paper tube procurement becomes easier.

The information displayed on the tag is not only information that can be read directly by humans such as letters, numbers, and symbols, but also barcodes converted into digital information aggregated into one-dimensional pattern information and "QR codes" converted into two-dimensional pattern information. A two-dimensional code such as "(registered trademark)" may be written together. When using digital information in this way, it is also preferable to include information on traceability such as the manufacturing time and location of the elastic bobbin winding body package. In addition, a registered trademark or logo of the elastic bobbin winding body package may be described. The information on the tag allows the user who uses the elastic thread winding body package to correctly identify using the information, and the information on the tag tells the elastic thread manufacturer about defects such as thread breakage during processing. It also becomes easier to request improvements.

The elastic yarn used in the present invention is not particularly limited, but polyurethane elastic fiber or polyurethane elastic yarn is a preferable example. The elastic yarn is a multifilament composed of a plurality of single yarns, and is usually an elastic yarn having 20 filaments to 120 filaments. The fineness of the elastic yarn is not particularly limited, but it is preferably applied to an elastic yarn having a fineness of 150 to 1300 decitex, which is called a medium-thick fineness product. Further, the cross section of the filament may be an aggregate in which these forms are combined, such as a round cross section, an ellipse, a peanut shape, and an eyebrow shape.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to those embodiments.
