[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a method for producing a disposable wearing article using an elastic sheet.
[0002]
[Prior art]
  Japanese Patent Laid-Open No. 2000-26015 discloses a method of cutting only an elastic member without damaging a base sheet with a roll cutter provided with ridges.
[0003]
  However, JP 2000-26015 A does not disclose sealing the base sheet while cutting the elastic member, improving air permeability of the base sheet while cutting the elastic member, or the like.
[0004]
[Problems to be solved by the invention]
  Therefore, in the present invention, a means for sealing the base web while cutting the elastic body or a means for improving the air permeability of the base web while cutting the elastic body is found. It aims at providing the manufacturing method of the disposable wear article | item utilized.
[0005]
[Means for Solving the Problems]
  Claim1The invention according to the present invention provides a first step of applying an adhesive to at least one of the first and second webs, and the first and second webs.pluralA second step of sandwiching an elastic body and generating a synthetic web composed of the first and second webs and the elastic body;By passing the synthetic web between an embossing roll having a plurality of convex portions and an opposing roll,A third step of cutting a part of at least one of the first and second webs and the elastic body;Contain,The plurality of convex portions are disposed so as to be separated from each other in the rotation axis direction of the embossing roll and overlap in the circumferential surface direction.It is the manufacturing method of the disposable wearing article characterized by the above-mentioned.
[0006]
  By cutting the elastic body in a region where it is preferable not to shrink by the third step and a part of at least one of the first web and the second web, a disposable wearing article that is beautiful and has excellent fit and breathability is obtained. It came to be obtained.
[0007]
  The third step is performed when the synthetic web passes between an embossing roll having a plurality of convex portions and an opposing roll, and the interval between the convex portions in the rotation axis direction of the embossing roll is 1 to 25 mm is a preferred embodiment of the present invention..
[0008]
  A first charge is applied to a region where the adhesive is to be applied on at least one of the first and second webs, and a second different from the first charge is applied to the applied adhesive. Is preferably applied. It is possible to prevent the adhesive from being applied to an unnecessary place.
[0009]
  At least one of a figure, a symbol, and a character is displayed on at least the first web, and in the third step, at least a part of a display area where at least one of the figure, the symbol, and the character is displayed In the embodiment in which the elastic body positioned above is cut, wrinkles are not generated in the display unit, so that figures and the like can be clearly recognized.
[0010]
  It is also the present invention that at least the second web has a region to which another member is to be bonded, and in the third step, the elastic body located under at least a part of the bonding region is cut. This is a preferred embodiment. This is because when the other members are bonded, the contraction force of the elastic body does not work and can be bonded cleanly.
[0011]
  The elastic body is preferably at least one of a thread shape, a belt shape, and a mesh shape, and a worn article having excellent breathability can be obtained.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, a first embodiment of the method of the present invention will be described with reference to the drawings. FIG. 1 is a perspective explanatory view showing a disposable wearing article manufacturing apparatus 1 for carrying out the first embodiment of the method of the present invention.
[0013]
  The manufacturing apparatus 1 includes an adhesive coating machine 13 that applies an adhesive to the first web 10, a guide guide 21 that guides the elastic body between the first web 10 and the second web 30, and the first web. 10 and the second roll 30 are pressed rolls 31 and 32, and the processing section 2 is used to cut or reduce the contraction force of at least a part of the elastic body of the synthetic web 40 overlapped by the press rolls 31 and 32. And. The adhesive may be applied to the second web 30.
[0014]
  The adhesive applicator 13 can apply the adhesive so as to provide the application portion 11 and the non-application portion 12 on the first web 10 having a predetermined width that flows in the X direction (flow direction). is there. It is preferable from the viewpoint of the air permeability of the synthetic web 40 that the adhesive coating machine 13 is for applying the adhesive by a spray coater, a curtain coater, a spiral coater or the like. The coating amount of the adhesive is preferably about 1 to 20 g / m2. The adhesive may be a hot melt. An example of the adhesive coating machine 13 will be described later.
[0015]
  An elastic body given a predetermined tension is supplied to the guide guide 21. As the elastic body, a plurality of elastic members 20 as shown in FIG. 1 can be used. As the elastic member 20, either a thread shape (thread rubber) or a band shape (flat rubber) can be used, and a mesh-like elastic body (for example, “rebound”) may be used. The guide guide 21 can reciprocate so as to cross the flow direction of the first web and the second web. At this time, the guide 21 can guide the elastic member 20 so as to draw a curve between the first web 10 and the second web 30. A predetermined tension is applied to the elastic member 20 supplied to the guide guide 21 by a tension roll (not shown).
[0016]
  The processing unit 2 includes an embossing roll 50 and an opposing roll 60 that faces the embossing roll 50. The synthetic web 40 is inserted between the embossing roll 50 and the opposing roll 60, and the processing unit 2 cuts at least a part of the elastic member 20 or reduces the contraction force of the part of the elastic member 20. The embossing roll 50 has an embossing part 51 having a plurality of convex parts. As will be described later, the convex portion may be configured to generate heat. The calorific value may be appropriately determined depending on the distance between the embossing roll 50 and the opposing roll 60, the shape and size of the convex portion, the material and cross-sectional area and shape of the elastic member 20, the flow speed of the synthetic web 40, and the like.
[0017]
  (A)-(d) of FIG. 2 is a front view which shows an example of the disposable wearing article manufactured using the synthetic | combination web 40 which passed the process part 2. FIG. The disposable wearing articles (for example, disposable pants or disposable diapers, hereinafter simply abbreviated as pants) 130, 140, and 150 in FIG. And a display area 41 in which a picture of a bear is omitted in (b) and (c). When the contraction force of the elastic member 20 located in the display area 41 is not reduced or lost, the contraction force causes a wrinkle in the display area 41, which makes it difficult for the bear to be seen as a bear and makes it look bad. However, when the contraction force of the elastic member 20 located in the display area 41 is reduced or disappears, the bear can be recognized as a bear like the pants 130 in FIG. It becomes. Although the elastic member 20 is located below the second web, the elastic member 20 (20a, 20b) is shown by a solid line for convenience of explanation.
[0018]
  Further, for example, even when a label on which a graphic or a character is displayed is pasted on the synthetic web 40, the label becomes wrinkled by the contraction force of the elastic member 20, and the appearance is deteriorated. Further, if wrinkles are present, the synthetic web 40, the above-mentioned label, or a fastening tape for fixing the diaper, a disposal tape for discarding worn articles manufactured using the synthetic web 40, etc. It is difficult to bond other members. Even if it is possible to bond the synthetic web 40 and another member by extending the heel, it is difficult to maintain the adhesion between the synthetic web 40 and the other member for a long time due to the contraction of the elastic member 20.
[0019]
  A pant 140 in FIG. 2B has an adhesive application part 11 and a non-application part 12 having substantially the same width as the display area 41, and the elastic member 20 is cut in the display area 41. Reference numeral 42 denotes a seal line or slit generated when the elastic member 20 is cut. The contraction of the cut elastic member 20 stops near the boundary between the application part 11 and the non-application part 12. When the synthetic web 40 has the non-application part 12, in order to eliminate the contraction force of the elastic member 20 in the display area 41, for example, as shown in FIG. The embossing roll 50 has at least two rows of convex portions spaced apart in the rotational direction, and the second row of convex portions is positioned between any of the adjacent convex portions of the first row. You may arrange | position a convex part. In FIG. 2B, the elastic member 20 is cut by the embossed portions 51 having two rows of convex portions, and at that time, a seal line (a slit when the second web 30 is also cut) 42 is formed. Even if the convex portions are in a line, the elastic member 20 can be cut when the convex portions are arranged so as to be diagonally overlapped. That is, when projecting the projections in the rotation direction of the embossing roll 50, the ends of the projection lines of the adjacent projections may overlap. Further, for example, the plurality of elastic members 20 may be cut by one convex portion. The length L2 of the embossed part 51 may be formed slightly shorter than the length L1 of the non-application part 12.
[0020]
  In order to eliminate the contraction force of the elastic member 20, the convex portion of the embossing roll 50 may be configured to generate heat. The convex portion temporarily melts at least a part of the second web 30 and a part of the elastic member 20, and the elastic member 20 is cut. Then, the first web 10 and the second web 30 are fused by the temporary melting of the second web. For example, in the case of the pants 140, the elastic member 20 is cut, and the first web 10 and the second web 30 are sealed to form the seal line 42. Even if the elastic member 20 is not completely cut, the wrinkle of the display region 41 is improved by reducing the contraction force of the elastic member 20.
[0021]
  Even if the protrusion does not generate heat, the elastic member 20 can be cut through the second web 30 if the width of the protrusion is narrow. At this time, at least a part of the second web 30 (a part in contact with the convex portion) is also cut, and the slit 42 enters the second web 30.
[0022]
  In the pants 150 in FIG. 2C, since the adhesive is also applied to the display area 41, the elastic member 20 located in the display area 41 is used to eliminate the contraction force of the elastic member 20 in the display area 41. Are preferably cut at predetermined intervals. By performing cutting or the like at predetermined intervals, the display area 41 is not biased in appearance. Therefore, it is preferable to arrange a plurality of convex portions in each row at a predetermined interval on the embossed portion 51. At this time, if the slits 42 are provided not only in the display area 41 but also in the waist part 151 and the crotch part 152, the air permeability is improved.
[0023]
  In addition, since the elastic member 20 is located below the second web 30, another new member (for example, a tape for discarding the pants or a pants-like shape is formed on the second web 30. When fastening a fastening tape, a label, or the like), the contraction force of the elastic member 20 existing at the fixing position may be eliminated in advance in the processing unit 2. This is because it is difficult to fix the member to the second web 30 when the pants are contracted by the contraction force of the elastic member 20.
[0024]
  The pants 160 in FIG. 2D is manufactured using the synthetic web 40 in which the mesh-like elastic member 20 is sandwiched between the first web 10 and the second web 30. In the body portion 161, it is preferable to leave the elastic yarn 20a in the horizontal direction of the mesh and cut the elastic yarn 20b in the vertical direction so that the pants 160 fit the wearer's body. For example, when another new member is bonded to a portion indicated by reference numeral 162, the elastic yarns 20 a and 20 b in the vertical direction and the horizontal direction are cut at the portion 162. Furthermore, the elastic yarns 20a and 20b in the vertical direction and the horizontal direction are also cut at the predetermined part 163 of the crotch. The predetermined portion 163 is a region where it is preferable that the pant 160 does not shrink. It is preferable that an absorber is disposed in such a region.
[0025]
  As described above, by reducing or eliminating the contraction force of the elastic member 20 of the synthetic web 40 at a position where another member is to be adhered, the synthetic web 40 and the other member can be adhered. As a method of reducing or eliminating the contraction force of the elastic member 20, the molecular structure of the elastic member 20 made of natural / synthetic rubber or thermoplastic elastomer that cuts the elastic member 20 to reduce the contracting force of the elastic member 20 is used. Various methods, such as changing a part of the synthetic web 40 to be changed and temporarily curing the melted part to restrain the contraction force of the elastic member, can be employed.
[0026]
  Next, the convex part of the embossed part 51 is demonstrated. FIG. 3A shows an emboss pattern in which a plurality of linear protrusions are arranged in a staggered manner. The embossed portion 51 includes n-1 rows of convex portions in which linear convex portions 53 and 53 having a length S1 and a width W1 are arranged at a distance D1 in the axial direction (black arrow direction) of the embossing roll 50. The protrusions 54 and 54 having the same length S1 and width W1 as the protrusion 53 are separated from the protrusion 53 by a distance M1 in the circumferential direction of the embossing roll 50 (in the direction of the white arrow), and The n rows of the projection group arranged so that the center line in the length direction passes through the point D1 / 2, and the projections 55 and 55 having the same shape as the projection 53 are arranged in the same arrangement as the projection 53. N + 1 columns of the convex portion group. The number of convex portions in one row is appropriately set depending on the number of elastic members 20 to be cut. The number of rows of the convex portion group is appropriately set according to the length L1 of the adhesive non-application portion 12. Here, the n column means the nth column, n is a natural number, and the 0 column means that no column exists.
[0027]
  Further, as another emboss pattern, n is a natural number of 2 or more, and n-1 rows of convex portions overlap with n + 1 rows of convex portions in a column direction of 1 mm or more (n-1 rows of convex portions and n + 1 rows of convex portions). The projections may be provided so that the projection line ends overlap each other when projected in the direction of the white arrow. At this time, the n-1 rows of protrusions may not overlap the n rows of protrusions in the column direction. In this pattern, compared with the embossing pattern shown in FIG. 3A, the density of the protrusions in a row can be reduced, and the embossing roll 50 can be easily manufactured.
[0028]
  In addition, the embossing roll 50 which has a convex part as mentioned above is easy to cut | disconnect the elastic member 20 because a convex part bites into the synthetic web 40 compared with the embossing roll which has a single blade.
[0029]
  FIG. 3B shows a pattern in which rhombic convex portions are arranged in a staggered manner. A row of convex groups in which the rhombic convex portions 56, 56 having the major axis S2 and the minor axis W2 are arranged at a distance D2 in the axial direction (black arrow direction) of the embossing roll 50, and the same rhombus as the convex portion 56 The convex portions 57 and 57 having a shape are arranged in the circumferential direction of the embossing roll 50 (in the direction of the white arrow) so that the convex portion 56 is separated from the distance M2 and the convex portion 57 is shifted by D2 / 2 in the axial direction. And a row of convex portions formed by convex portions 58 and 58 having the same shape as the convex portions 56 and having the convex portions 56 shifted in the circumferential direction by 2W2 + 2M2. Of course, also in this pattern, the number of convex portions in one row depends on the number of elastic members 20 to be cut and the like, and the number of rows in the convex portion group depends on the length L1 of the adhesive non-applied portion 12 as appropriate. Is set.
[0030]
  The length S1 of the linear protrusion and the long axis S2 of the rhombus are in the range of 1 to 25 mm. 2-25 mm is more preferable. In addition, when the separation distances D1 and S1 between adjacent convex portions are the same or S1 is longer, the elastic member 20 positioned between the convex portions 53 and 53 is formed by the convex portion 54 due to the staggered arrangement. It can be cut reliably. Similarly in D2 and S2, D2 ≦ S2 may be satisfied. If S1 or S2 is shorter than 1 mm, there is a possibility that the elastic member 20 cannot be cut. If it is longer than 25 mm, the area of the seal portion becomes too large and the feeling of touch becomes worse. The range of D1 and D2 is also in the range of 1 to 25 mm, and D1 is more preferably 2 to 25 mm. When the convex portion is a rhombus, when the corner portions of the convex portions adjacent to each other in the roll circumferential direction are slightly overlapped when viewed from the elastic member attaching direction, the elastic member 20 escapes from the convex portion depending on the arrangement of the convex portions. Since D2 may not be cut, D2 is more preferably 3 to 10 mm.
[0031]
  The width W1 of the linear protrusion and the short axis W2 of the rhombus are preferably 0.5 to 15 mm when a part of the synthetic web 40 is temporarily melted. When all of the second web 30 and the elastic member 20 are cut, W1 is preferably several μm to 0.5 mm. In addition, it is not preferable that W1 and W2 are thicker than 15 mm because the area of the seal portion becomes too large and the touch feeling becomes worse. As for W2, the lower limit is more preferably 1 mm or more.
[0032]
  The distance between the rows of the convex group is not particularly limited, but M1 or M2 is preferably 1 to 25 mm. The shape of the convex portion is not limited to the above-mentioned linear shape or rhombus shape, but can be applied to diagonal lines, circular shapes, triangular shapes, star shapes, heart shapes, clover shapes, crescent shapes, and other polygonal shapes. It can be changed according to each row of convex portions.
[0033]
  FIG. 4 schematically shows an example of a state where the elastic member is cut. In the figure, it is assumed that the synthetic web 40 flows downward. The region 11 is an application part, and the region 12 is a non-application part. The left elastic member 22 is cut by a seal portion 70 (corresponding to the convex portion 53), and its end portion 22a is released from the tension state, and either one of the first web 10 and the second web 30 is used. The elastic member 22 is bonded and fixed to the elastic member 22 and contracts. If the remaining elastic member is captured by the convex portion 55 before the cutting by the convex portion 53 is completed, the elastic member 22b existing between the convex portion 53 and the convex portion 55 is sealed when the convex portion 53 cuts. Shrink to the side. When the cutting by the convex portion 53 is completed before the remaining elastic member is captured by the convex portion 55, the elastic member (not shown) existing in the downstream application portion contracts. Further, the elastic member 23 on the right side is also cut by the closest seal portion 71 (corresponding to the convex portion 54), and the end portion 23a contracts.
[0034]
  With the above configuration, the elastic member is cut and a large number of small seal portions are formed in the non-stretchable portion, and the first web and the second web are joined also in the non-application portion. Since each sealing part is spaced apart and small one by one, even if the nonwoven fabric is formed into a film by heat sealing, for example, it is less likely to give discomfort to the wearer than in the case of a continuous line.
[0035]
  Next, an example of an adhesive coating machine will be described. Fig.7 (a) is side explanatory drawing which shows an example of an adhesive coating machine. The adhesive coating machine 13a applies an adhesive (for example, hot melt; hereinafter, hot melt will be described as a representative) to the plus, sprays the gun part 100, and is positioned under the first web 10, and ground or It has the conductor part 101 applied to minus. In general, all of the hot melt ejected from the gun unit 100 does not adhere to the material to be coated such as the first web 10 but is partially suspended in the air. However, as described above, by charging the hot melt, it can be efficiently attached to the first web 10. In addition, the hot melt can be less scattered in the width direction of the first web 10 and the accuracy in the width direction is improved. Furthermore, in the case of intermittent bonding in the flow direction, the direction (flow direction) orthogonal to the width direction of the first web 10 is controlled by controlling the time during which hot melt is sprayed and the potential of the gun part 100 or the conductor part 101 part. It is possible to increase the accuracy of the hot melt adhesion position. Note that the polarity of the applied voltage may be reversed. Moreover, you may apply the voltage of the same polarity as an adhesive agent to the part which does not want to apply | coat an adhesive agent.
[0036]
  The conductor 101 may be composed of a plurality of electrode plates 101a and 101b as shown in an overhead view in FIG. For example, by using a plurality of gun parts 100 and setting the distance between the electrode plates 101a and 101b to a predetermined distance and applying hot melt to which electric charges are applied, the predetermined distance is separated in the width direction. It is possible to apply the hot melt in such a state that there is a non-application part in the width direction.
[0037]
  Further, the conductor portion 101 may be a roller 102 as shown in a perspective view in FIG. The roller 102 rotates substantially in synchronization with the first web 10. The roller 102 has a conductive portion 103 and a nonconductive portion 104. As described above, since the hot melt is charged to the first polarity, if the conductive portion 103 is grounded or a voltage having a polarity opposite to the first polarity is applied, the conductive portion 103 Hot melt can be applied to the first web 10 in substantially the same shape. If the polarities of the electric charges of the conductive portion 103 and the hot melt are the same, the hot melt is not applied to the portion corresponding to the conductive portion 103 of the first web 10.
[0038]
  The shape of the conductive portion 103 is determined according to the shape to which the hot melt is to be applied to the first web 10. The hot melt is discharged from the gun unit 100 a predetermined time before the time when the top of the hot melt application unit passes the installation position of the gun unit 100, and the rear end of the application unit indicates the installation position of the gun unit 100. The hot melt discharge is stopped a predetermined time before the passing time. With such a configuration, the hot melt can be adhered to substantially coincide with the portion to be applied. The roller 102 may be located on the upstream side of the gun unit 100.
[0039]
  Moreover, it cannot be overemphasized that the adhesive coating machine mentioned above may be used in order to manufacture products other than disposable wearing articles. That is, after the hot melt is applied, nothing may be sandwiched between the first web and the second web. After the hot melt is applied, members other than the web material are bonded by the hot melt. May be.
[0040]
  The hot melt may be applied continuously without providing a non-application portion. This is a more preferable embodiment because the line speed can be further increased as compared with the case where the application part and the non-application part are provided intermittently. The first web 10 and the second web 30 are not cut by passing the embossing roll 50 after the elastic member 20 is sandwiched between the first web 10 and the second web 30 to which hot melt is continuously applied. In addition, only the elastic member 20 is cut. After the cutting, as shown in FIG. 5, the elastic member 24 is in a relaxed state and is held by two (or three or more) seal portions 59 and 59. Therefore, even when hot melt is continuously applied, the seal portion becomes non-stretchable by changing the type, application amount, and application direction of the hot melt. Further, when the elastic member 20 is cut by heat, the hot melt is remelted by the heat of the embossing roll 50 and becomes soft, the restraining force of the elastic member 20 by the hot melt is weakened, and the elastic recovery force of the elastic member 20 is overcome. Therefore, it is considered that the elastic member 20 is joined to the seal portion in a relaxed state.
[0041]
  Next, a second embodiment of the present invention will be described. In 2nd Embodiment, it replaces with the embossing roll which has the convex part spaced apart, and has 1-25 mm in length, a recessed group of widths 0.5-15 mm, and the width | variety of a crosspiece is 0.5-5 mm An embossing roll having a grid-like convex portion is used. As shown in FIG. 6, the grid-like convex portion 63 is formed by crossing a plurality of crosspieces 61, 61... In a cross-beam shape, and a space 62 surrounded by the crosspieces 61 is a concave portion (lattice). W3 is the width of the crosspiece and is 0.5 to 5 mm. If the width of the crosspiece is too thick, the tactile sensation is deteriorated, but if it is thinner than 0.5 mm, the second web 30 and the first web 10 may be cut. The length of the lattice-shaped recess is D3, preferably 5 to 25 mm, more preferably 5 to 10 mm. The width | variety of a grid | lattice-like recessed part is M3, 5-25 mm is preferable, More preferably, it is 5-10 mm.
[0042]
  Although an oblique lattice is shown in FIG. 6, it may of course be a polygonal lattice such as a square or a rectangle. In this embodiment, since it is sealed in a lattice shape, the elastic member 20 can be cut reliably. Moreover, since the thin grid | lattice-like convex part exists in a certain area part, and it is mesh shape, the elastic member 20 should just be cut | disconnected by one of sealing parts. When sealing with a single blade, since all the elastic members 20 must be cut with a single blade, it is necessary to seal strongly so that there is no elastic member 20 that is not cut. The first web 10 may be broken, but in the above configuration, the elastic member 20 only needs to be cut at one of the seal portions, so that it is not necessary to seal strongly, and the surface is pressure-contacted. For this reason, the sheet does not break. In addition, the lattice-like seal portion is soft to the wearer and has a beautiful appearance. Also in the second embodiment, a hot melt adhesive application part and a non-application part may be provided, or a method of applying continuously without providing a non-application part may be employed.
[0043]
  One of the embossing roll 50 and the opposing roll 60 shown in FIG. 1 may include a heating means. A rod-like sheathed heater may be provided near these rolls, or another heating means such as a high-frequency heating means, a far-infrared heater, or an oil heater may be used in combination. In FIG. 1, a configuration in which the positions of the embossing roll 50 and the opposing roll 60 are reversed can also be employed.
[0044]
  One of the first web 10 and the second web 30 is preferably heat-fusible. Nonwoven fabric, plastic film, knitted fabric, woven fabric, paper and the like can be used. As the material, known materials such as polypropylene, polyethylene, polyester, cellulose, rayon and the like can be appropriately used alone or in admixture of two or more. Each of the webs 10 and 30 may be a multilayer sheet in which several sheets are already laminated. In this case, heat fusion is applied to the uppermost surface of the first web 10 or the lowermost surface of the second web 30. It is necessary to provide a protective sheet.
[0045]
  As the elastic member 20, a material that can be melted and cut (for example, thermoplastic polyurethane, various elastomers, rubbers, etc.) in a band shape, a thread shape, or a mesh shape can be used. Further, a film-like elastic member (elastomer film or the like) can also be used because it can be surely cut by the staggered array or the lattice-shaped array of seal portions. As the elastic member 20, it is preferable to select an elastic member made of a material whose melting point is lower than the melting point of the heat-fusible material in the second web 30 so as not to cut the first and second webs 10 and 30. The melting point of the second web 30 may be higher than that of the first web 10.
[0046]
  Although FIG. 1 shows an example in which an elastic member is bonded to the central portion in the width direction of the web, it is needless to say that an elastic member may be bonded near the end of the web. What is necessary is just to change the arrangement | positioning part of an embossing pattern according to the attachment position of an elastic member.
[0047]
【The invention's effect】
  According to the method of the present invention, the seal part after heat sealing can be made non-stretchable not only when the adhesive is applied so as to provide a non-application part and an application part, but also when continuously applied. For this reason, the synthetic web (elastic sheet) which has an expansion-contraction part and a non-expansion part alternately can be manufactured continuously.
