Description

  The present invention relates to a roll-shaped laminated continuous sheet in which a laminated continuous sheet formed by laminating an upper layer sheet and a lower layer sheet having a belt shape is wound in a roll shape.

  In a roll-like sanitary paper in which a sanitary paper such as a toilet roll or kitchen roll is wound in a roll shape, the paper itself is often required to have a certain degree of flexibility and touch. In order to satisfy such a requirement, a laminated continuous sheet formed by laminating a plurality of thinner sheets is employed. In this case, Patent Document 1 discloses a technique for mechanically embossing and stamping the laminated continuous sheets to integrally bond them so that the plurality of sheets in a laminated state do not peel from each other. Proposed.

JP 2002-227099 A

  When embossing or stamping (hereinafter referred to collectively as embossing for convenience) is performed on these sheets so that the laminated sheets do not peel from each other, the embossing position is the width of the continuous sheet. If the direction is always continuous at a certain position, a problem occurs. That is, as a result of a part of the outer peripheral surface of the wound roll-shaped laminated continuous sheet being swelled in an annular shape due to the stacking of embossing, the appearance of the roll-shaped laminated continuous sheet is impaired.

  Therefore, in Patent Document 1, design embossing is performed so that an embossed pattern is formed on the entire surface of the laminated continuous sheet that is not subjected to bonding embossing for bonding the laminated continuous sheet. . Furthermore, by reducing the size of the embossed portion formed by the embossing for bonding than the individual embossed portions formed by the embossing for the design, a decrease in the appearance of the appearance is suppressed.

  However, the bonding embossed part proposed in Patent Document 1 is greatly different from the appearance of the design embossing part, and these are formed in separate areas. There is no change in being easily visible. Therefore, it is unsatisfactory in terms of improving the appearance of the appearance, and further improvements are desired.

  An object of the present invention is to provide a roll-shaped laminated continuous sheet that can significantly improve the appearance of the appearance due to embossing for bonding in a laminated continuous sheet obtained by laminating an upper layer sheet and a lower layer sheet having a belt shape.

A roll-like laminated continuous sheet according to the present invention in which a laminated continuous sheet formed by laminating a belt-like upper layer sheet and a lower layer sheet is wound in a roll shape is continuously along the width direction and the longitudinal direction of the upper layer sheet. A plurality of first embossed portions formed on the upper sheet so as to define a repetitive embossing pattern, and an upper bonding emboss for defining a bonding area where the upper sheet and the lower sheet are in close contact with each other And a joint region in which the upper layer sheet and the lower layer sheet are in close contact with the upper joint embossed portion, and the upper layer sheet and the lower layer sheet are integrally joined with the upper joint embossed portion. An embossing portion for lower joining for performing at least one of the upper and lower joining embossing portions with respect to the width direction and the longitudinal direction of the laminated continuous sheet. Arranged at each predetermined interval along the respective inclined direction, and wherein the area of each of the top of the bonding embossed portions arranged at fixed intervals is less than the area of the top portion of each of the first embossed portion .

  In the present invention, the upper layer sheet and the lower layer sheet are integrally bonded in the bonding region of the upper bonding embossed portion and the lower bonding embossed portion. The upper bonding embossed portion is in a state of being mixed into the embossed pattern formed by the first embossed portion.

  Note that the description of “joining embossing” described in the present specification includes not only embossing but also a state according to a processing form such as stamping accompanied by deformation of a workpiece. Therefore, in the present invention, it is possible to form the “joining emboss” on the workpiece using a stamping roll or the like instead of the embossing roll for forming the “joining emboss”.

  It is preferable that the interval between the joining regions of at least one embossing portion adjacent to each other along the longitudinal direction of the laminated continuous sheet is equal to or less than the length of each matching region along the longitudinal direction of the laminated continuous sheet.

  Further, the arrangement interval of at least one bonding embossed portion inclined with respect to the width direction of the laminated continuous sheet and the arrangement interval of at least one bonding embossed portion inclined with respect to the longitudinal direction of the laminated continuous sheet are the same. It may be.

  The upper and lower bonding embossed portions can be formed close to both side edges in the width direction along the longitudinal direction of the laminated continuous sheet.

  The other of the embossed portions for the upper and lower joints may have a continuous planar shape or groove shape.

  The joining area | region by the other embossing part for joining may exist in the same position as the surface of the upper layer sheet in which the 1st embossing part is not formed regarding the thickness direction of an upper layer sheet.

  It is preferable to protrude the first embossed portion toward the lower layer sheet.

  Each embossing pattern may have a point-symmetric shape in which the first embossed portions are concentrically arranged, a rotationally symmetric shape, or a spiral shape.

  It is preferable that the arrangement direction of the emboss pattern is inclined with respect to the width direction and the longitudinal direction of the laminated continuous sheet.

  A plurality of second embossed portions having a truncated cone shape formed in the lower layer sheet at predetermined intervals along the width direction and the longitudinal direction of the laminated continuous sheet so as to protrude toward the upper layer sheet side can be further provided.

  According to the roll-shaped laminated continuous sheet of the present invention, the upper bonding embossed portion is in a state of being included in the embossed pattern formed by the first embossed portion. For this reason, the visibility of the embossing part for joining falls rather than the conventional one, and the fall of the appearance of the roll-shaped lamination continuous sheet by having formed the embossing part for joining can be suppressed significantly. Moreover, since at least one of the upper and lower bonding embossed portions is arranged at regular intervals along the direction inclined with respect to the width direction and the longitudinal direction of the laminated continuous sheet, the embossing roll during the embossing Periodic vibration can be suppressed.

  When the interval between the bonding areas by one of the adjacent embossing portions along the longitudinal direction of the laminated continuous sheet is set to be equal to or less than the length of each bonding area, the periodic vibration of the embossing roll during the embossing is reduced. This can prevent the generation of noise further. In addition, the replacement life can be extended.

  When the arrangement interval of at least one embossing part for joining inclined with respect to the width direction of the laminated continuous sheet is the same as the arrangement interval of at least one embossing part for joining inclined with respect to the longitudinal direction of the laminated continuous sheet, Therefore, the embossing roll can be easily manufactured.

  When the embossed portion for bonding is formed close to both side edges in the width direction along the longitudinal direction of the laminated continuous sheet, both side edges in the width direction of the continuous laminated sheet that are easily peeled are joined, and the upper sheet and Peeling from the lower layer sheet can be prevented more reliably.

  When the other of the embossed portions for upper and lower joining forms a continuous planar shape or groove shape, the adhesion between the upper layer sheet and the lower layer sheet can be further enhanced.

  In the thickness direction of the upper layer sheet, when the bonding region by the other bonding embossed portion is set at the same position as the surface of the upper layer sheet where the first embossed portion is not formed, the deformation of the upper layer sheet by the upper bonding embossed portion is reduced. be able to. As a result, the visibility of the bonding embossed portion is further lowered, and the deterioration of the appearance of the roll-shaped laminated continuous sheet due to the formation of the bonding embossed portion can be further suppressed.

  When the 1st embossed part protrudes in the lower layer sheet side, the touch of the surface of a lamination | stacking continuous sheet can be kept favorable.

  When each embossing pattern has a point-symmetric shape in which the first embossed portions are arranged concentrically, the joining embossed portion can be further mixed into the embossed pattern. As a result, it is possible to further suppress a decrease in appearance due to the formation of the bonding embossed portion.

  Similarly, when the arrangement direction of the emboss pattern is inclined with respect to the width direction and the longitudinal direction of the laminated continuous sheet, the joining embossed portion can be further infiltrated into the emboss pattern. As a result, it is possible to further suppress a decrease in appearance due to the formation of the bonding embossed portion.

  When a large number of second embossed portions are formed in the lower layer sheet at predetermined intervals along the width direction and the longitudinal direction of the laminated continuous sheet so as to protrude to the upper layer sheet side, the flexibility and feel of the continuous laminated sheet are further improved. Can be made.

  One embodiment in which the roll-shaped laminated continuous sheet according to the present invention is applied to a toilet roll will be described in detail with reference to FIGS. However, the present invention is not limited to such an embodiment. For example, any roll-like laminate in which a laminated continuous sheet formed by laminating a lower layer sheet and an upper layer sheet in a strip shape is wound into a roll shape such as a kitchen roll. It can be applied to continuous sheets.

  The appearance of the toilet roll in the present embodiment is shown in FIG. 1, the front shape of a part of the laminated continuous sheet is shown in FIG. 2, and the cross-sectional shape along the III-III arrow is extracted and enlarged and schematically shown. 3 shows. The toilet roll 10 according to this embodiment is obtained by winding a laminated continuous sheet 13 in which two tissues 11 and 12 are overlapped on a cylindrical core 14 for a predetermined length. In the present embodiment, one tissue (hereinafter referred to as a surface tissue) 11 corresponds to the belt-like upper layer sheet in the present invention, and the other tissue (hereinafter referred to as a back surface tissue) 12 is a book. This corresponds to the belt-like lower layer sheet in the invention.

  In the present embodiment, the two continuous layers of tissue 11 and 12 are overlapped to form the stacked continuous sheet 13. However, one or more sheets are further stacked and stacked continuously between the upper layer sheet and the lower layer sheet. You may make it comprise a sheet | seat. That is, it should be noted that the laminated continuous sheet in the present invention includes at least an upper layer sheet and a lower layer sheet, and includes those obtained by laminating three or more sheets.

A large number of first embossed portions 11 a are formed on the front surface tissue 11 so as to protrude toward the overlapping surface 15 with the back surface tissue 12. Thus, by making the 1st embossed part 11a protrude from the surface of the surface tissue 11 to the back surface tissue 12 side, the touch of the surface of the surface tissue 11 opposite to the overlapping surface 15 can be kept good. Each of the first embossed portions 11a has a truncated cone shape having a top diameter of 1 mm, a height of 0.8 mm, and a vertex angle of 40 degrees. However, it is not necessarily limited to such a dimensional shape. These first embossed portions 11a define an embossed pattern P that repeats continuously along the width direction (left-right direction in FIG. 2) and the longitudinal direction (up-down direction in FIG. 2) of the surface tissue 11. Each emboss pattern P in this embodiment is set so that one side surrounded by a two-dot chain line in FIG. 2 occupies a substantially square area of about 28.5 mm, and the first embossed portions 11a are arranged concentrically. A point-symmetric shape is formed. In the present embodiment, the density is such that, on average, about 21 first embossed portions 11 a per 1 cm ² are arranged on the surface tissue 11. However, it is not limited to such a density. Further, as will be apparent from FIG. 2, the arrangement direction of these embossed patterns P is slightly inclined (7.5 degrees in the illustrated example) with respect to the width direction and the longitudinal direction of the laminated continuous sheet 13.

  In the present embodiment, each emboss pattern P is set so as to occupy a substantially square area, but may be set so as to occupy an equilateral triangle area and arranged in a dense state. Moreover, even if these embossed patterns are the ones in which the first embossed parts 11a are arranged in a spiral shape at regular intervals, or the first embossed parts 11a are arranged in a rotationally symmetrical shape along an arbitrary curve. Good.

The back surface tissue 12 is arranged along a direction inclined by a predetermined angle (45 degrees in the illustrated example) with respect to the width direction and the longitudinal direction of the back surface tissue 12 so as to protrude toward the overlapping surface 15 with the front surface tissue 11. A large number of second embossed portions 12a are formed at predetermined intervals. Similar to the surface tissue 11, the second embossed portion 12 a protrudes from the surface of the back surface tissue 12 toward the surface tissue 11, so that the surface texture of the back surface tissue 12 on the side opposite to the overlapping surface 15 is kept good. be able to. Each of the second embossed portions 12a has a truncated cone shape with a top diameter of 0.4 mm, a height of 0.75 mm, and a vertex angle of 40 degrees, and is formed on the back surface tissue 12 at a density of about 60 per 1 cm ^2. It is arranged. Accordingly, the interval between the second embossed portions 12a adjacent to each other in the arrangement direction is about 1.3 mm. However, it is not necessarily limited to these numerical values.

  As described above, the embossed portions 11a and 12a projecting to the overlapping surface 15 side are formed on the front surface tissue 11 and the back surface tissue 12, and therefore, combined with the good touch on both the front and back surfaces of the laminated continuous sheet 13. Its flexibility can be improved.

  The embossed portions 11b and 12b for joining that define a joining region C that integrally joins the front surface tissue 11 and the back surface tissue 12 in proximity to each other in the widthwise side edges of the laminated continuous sheet 13. Is formed. Thereby, peeling with the surface tissue 11 and the back surface tissue 12 from the width direction both sides edge part of the lamination | stacking continuous sheet 13 can be suppressed. Also, the joining region C is formed within the thickness range of the laminated continuous sheet 13 including the first embossed portion 11a and the second embossed portion 12a, and the embossed portions 11b and 12b for joining project outward from both the front and back surfaces of the laminated continuous sheet 13. It is not in a state. For this reason, the phenomenon like the conventional toilet roll which a part of outer peripheral surface swells cyclically | annularly by the stacking of the embossing for joining does not generate | occur | produce, and the appearance of the external appearance of a roll-shaped lamination | stacking continuous sheet can be kept favorable.

  The upper bonding embossed portion 11 b formed on the surface tissue 11 side has a continuous planar shape along the longitudinal direction of the laminated continuous sheet 13. In the present embodiment, the bonding region C formed by the upper bonding embossed portion 11b is set at the same position as the surface of the surface tissue 11 where the first embossed portion 11a is not formed in the thickness direction of the surface tissue 11. Thereby, the groove-shaped depression by the 1st embossed part 11a is not substantially formed in the surface of surface tissue 11, and the fall of the appearance of lamination continuous sheet 13 can further be controlled.

  A number of lower bonding embossed portions 12b are formed on the back surface tissue 12 side by an embossing roll 16 whose outer peripheral surface is shown in a developed shape in FIG. The lower bonding embossed portions 12b are arranged at regular intervals along the direction inclined with respect to the width direction and the longitudinal direction of the laminated continuous sheet 13, respectively. In the present embodiment, the arrangement interval of the lower bonding embossed portions 12b inclined with respect to the width direction of the laminated continuous sheet 13 and the arrangement interval of the lower bonding embossed portions 12b inclined with respect to the longitudinal direction of the laminated continuous sheet 13 Are set the same. Further, the inclination angles α and β in the arrangement direction of the lower bonding embossed portions 12b with respect to the width direction and the longitudinal direction of the laminated continuous sheet 13 are set to 25 degrees. Thereby, the distribution state of the embossing part 12b for lower joining along the width direction and longitudinal direction of the lamination | stacking continuous sheet 13 can be made more uniform.

  The upper bonding embossed portion 11b is formed so as to protrude from the front surface tissue 11 side to the back surface tissue 12 side so that the front surface tissue 11 and the back surface tissue 12 are in close contact with each other, and the width of the groove bottom is set to about 2.6 mm. . As described above, the bonding region C of the upper bonding embossed portion 11b in this embodiment is set at the same position as the surface of the surface tissue 11 where the first embossed portion 11a is not formed in the thickness direction of the surface tissue 11. Has been. For this reason, the front tissue 12 is not substantially formed with a recess protruding toward the back surface tissue 12 by the first embossed portion 11a. However, when the bonding region C of the upper bonding embossed portion 11b is closer to the overlapping surface 15 than the illustrated example, for example, when it is positioned on the overlapping surface 15 as shown in FIG. 5, the upper bonding embossed portion 11b. Note that is formed in a continuous groove shape. The lower bonding embossed portion 12b is formed so as to protrude from the back surface tissue 12 side to the front surface tissue 11 side so that the front surface tissue 11 and the back surface tissue 12 are in close contact with each other. The lengths of the top and base sides of the lower joint embossing portion 12b having a regular quadrangular pyramid shape are set to 0.3 mm, 1.256 mm, height 0.66 mm, and apex angle 70 degrees, respectively. However, it is not necessarily limited to these numerical values, and the shapes of the bonding embossed portions 11b and 12b formed on the front surface tissue 11 and the back surface tissue 12 can be reversed.

  When the lower bonding embossed portions 12b are arranged in a regular quadrangular pyramid shape, the convex surface 16a of the embossing roll 16 having a cross-sectional shape as shown in FIG. It can be manufactured with high accuracy.

  When the above-described joining embossing portions 11 b and 12 b are processed using the pair of metal embossing rolls 16 and 17, one embossing roll 16 is elastically applied to the other embossing roll 17 such as a spring or air pressure. It is necessary to press with. Since the convex portion 16a for forming the bonding embossed portion 12b is intermittently formed along the circumferential direction on the outer peripheral surface of one embossing roll 16, the following state occurs. That is, every time the convex portion 16 a presses against the smooth outer peripheral surface 17 a of the other embossing roll 17 with the laminated continuous sheet 13 interposed therebetween, the one embossing roll 16 vibrates so as to be separated from the other embossing roll 17. . As a result, there is a problem in that noise is easily generated or the convex portion 16a is easily worn and the life of the embossing roll 16 on which the convex portion 16a is formed is shortened. However, by appropriately setting the interval between the lower bonding embossed portions 12b adjacent to each other along the longitudinal direction of the laminated continuous sheet 13, the convex portion 16a apparently follows the outer peripheral surface of the embossing roll 16 along the circumferential direction. And can be formed continuously. This is because the gap G at the top of the lower bonding embossed portion 12b adjacent along the longitudinal direction of the laminated continuous sheet 13 is less than the length of the top of the lower bonding embossed portion 12b along the longitudinal direction of the laminated continuous sheet 13. It can be almost achieved by setting. As a result, one embossing roll 16 can be rotated at substantially the same position, and the embossing roll 16 does not vibrate and noise is less likely to occur. Moreover, the wear of the convex portion 16a is reduced, and the life of the embossing roll 16 can be extended. In other words, the arrangement direction of the protrusions 16 a is an appropriate angle with respect to the width direction of the laminated continuous sheet 13 according to the distance between the tops of the embossed portions 12 b for lower joining along the longitudinal direction of the laminated continuous sheet 13 and the dimensions thereof. Just tilt it. Empirically, the gap G at the top of the lower bonding embossed portion 12b adjacent in the longitudinal direction of the laminated continuous sheet 13 may be set to about 0.3 mm or less. It is effective to set the angles α and β in the range of 15 to 29 degrees.

  In this laminated continuous sheet 13, perforations for breaking that cross the laminated continuous sheet 13 in the width direction can be further formed at regular intervals along the longitudinal direction.

  A manufacturing facility for such a toilet roll 10 is schematically shown in FIG. An original fabric surface tissue roll 11R and an original fabric reverse surface tissue roll 12R are arranged on the original fabric tissue stand 18, and these original fabric tissue rolls 11R, 12R are two to two times the width of the toilet roll 10 as a product. It has a width of a dozen times. An embossing section 19 is disposed adjacent to the raw tissue stand 18, and a winding section 20, a terminal processing section (not shown), and a cutting section are disposed in this order. Elongated tissue 11L, 12L having a strip shape drawn from the original fabric surface tissue roll 11R and the original fabric reverse surface tissue roll 12R is embossed at the embossing portion 19, and the first and second embossed portions 11a, 11a, 12a is formed. As a result, tension and flexibility are given to the long tissues 11L and 12L, and the long tissues 11L and 12L are overlapped with each other at the embossed portion 19 to form a laminated state. A plurality of pairs of embossing rolls 16 and 17 are arranged on a winding unit 20 on which a long winding core 14 (see FIG. 1) (not shown) is arranged. These embossing rolls 16 and 17 are for forming the embossing portions 11b and 12b for joining on the long laminated continuous sheet 13L formed by superposing the long tissues 11L and 12L. The long continuous laminated sheet 13L having a predetermined length on which the embossed portions 11b and 12b for bonding are formed by the embossing rolls 16 and 17 is wound around the long core 14. In the end treatment section, the end of the long laminated continuous sheet 13L having a predetermined length is glued to the surface of the long toilet roll 10 (see FIG. 1) wound around the long winding core 14, and then cut. To the cutting section. The base end of the long laminated continuous sheet 13L remaining after the cutting is wound around a new long winding core 14 disposed in the winding unit 20, and the long laminated continuous sheet 13L having a predetermined length is again formed into this long length. It is wound around the winding core 14. In the cutting part, the long toilet roll 10 is cut into a predetermined width by a cutter (not shown) to form individual toilet rolls 10.
