Description

  The present invention relates to a tissue paper product and a manufacturing method thereof, and more particularly to a tissue paper product manufactured using a multi-stand type interfolder and a method of manufacturing a tissue paper product using a multi-stand type inter folder.

  In tissue paper products, bundles of multiple tissue papers are stored in a storage box, and bundled via an outlet provided on the upper surface of the storage box (also referred to as a carton or tissue carton). Pull out the tissue paper one by one and use it one after another (the type in which the next one is drawn out from the outlet when it is taken out is also called a pop-up type).

  The tissue paper in the tissue paper product is usually made into a set of two sheets, which are fixed by contact embossing (also called ply embossing) arranged along the edge on each side edge so that each does not peel off It has become.

  The flow of manufacturing such tissue paper products is as follows. First, a thin paper (also referred to as crepe paper) having a crepe is made in a papermaking facility, and the resultant is wound to produce a primary raw roll (generally also referred to as a jumbo roll).

  Next, after setting the required number of primary rolls in a ply machine, unwinding a single-layer primary continuous sheet from each primary roll and laminating and laminating, fixing each sheet with contact embossing Then, it is slit into a width of tissue paper or a multiple of the width of the tissue paper to produce a wound secondary multilayer roll.

  Next, set the required number of secondary rolls in the interfolder, feed the secondary continuous sheets from each secondary roll, supply them, fold the secondary continuous sheets and stack them one after another to make a stack of tissue paper To manufacture. The bundle of tissue paper is stored in a storage box to obtain a tissue paper product.

  As the interfolder for manufacturing the bundle, there is a multi-stand type (multiple type) inter-folder, and the multi-stand type inter-folder has a large number of folding mechanism portions having a pair of folding plates in the line flow direction (usually 80 to 120 machines) are arranged in parallel. When two secondary continuous sheets having the same width as the tissue paper are arranged and supplied simultaneously to each folding mechanism part, the two secondary continuous sheets overlap each other in each folding mechanism part in the width direction. A secondary continuous sheet folded back by a folding mechanism section downstream of the line is sequentially laminated on another secondary continuous sheet that has been folded and folded by the folding mechanism upstream of the line, and is most downstream. In the above, a laminated continuous sheet in which the required number of sheets is laminated is formed. A bundle of tissue paper is formed by sequentially cutting the laminated continuous sheet.

  Traditionally, tissue paper products have been manufactured in this way, especially in the multi-stand type interfolder, in the process of transporting the secondary continuous sheet fed from the secondary raw fabric roll to the folding mechanism part or folding folding plate. When the secondary continuous sheet is folded back, distortion, bending, and wrinkles occur, and the subsequent stacked continuous sheets and bundles become too bulky and too high to be inserted into the storage box. There was a problem that it became a product containing paper.

JP2007-63695 JP 2009-291884 A JP 2002-347146 A JP 2010-220766 US Patent No. 4052048 (Japanese Patent Publication No. 55-1215) JP 2006-240750 A

  Therefore, the main problem of the present invention is a method of manufacturing a pop-up type tissue paper product that manufactures a bundle with a multi-stand type interfolder. This is to prevent the occurrence of bending and distortion, and to improve the productivity and production speed of tissue paper products.

Means for solving the above problems and their effects are as follows.

And, at least one of the rolls around which the secondary continuous sheet is wound between the secondary raw roll and the folded folding plate is used as a crown roll or an expander roll, and the one edge portion through the crown roll or the expander roll A method for producing a tissue paper product, in which a secondary continuous sheet having contact embossing only is supplied to a folded plate.

[Invention of Claim 2]
The method for producing a tissue paper product according to claim 1, wherein the feeder roll immediately before the folded plate is a crown roll or an expander roll.

[Invention of Claim 3]
The method for producing tissue paper according to claim 1 or 2, wherein the secondary continuous sheet is formed such that contact embossing at one edge is intermittently formed along the edge.

[Invention of Claim 4]
The manufacturing method of the tissue paper of Claims 1-3 which folds a secondary continuous sheet with a folding plate so that the edge with contact embossing may become an upper side.

[Invention of Claim 5]
A bundle of folded and stacked rectangular tissue paper is a tissue paper product stored in a storage box having an outlet on the top surface,
The tissue paper is provided with contact embossing intermittently formed along only one edge of both side edges in the CD direction,
The bundles are stacked in a staggered manner so that the tissue paper is folded in two in the CD direction, and the edges of the folded pieces are positioned on the folded inner surface of other tissue paper adjacent vertically. The tissue paper product characterized in that the edge located on the upper surface side of the storage box is an edge provided with contact embossing.

(Function and effect)
In the production method of the present invention, as the secondary continuous sheet, a sheet having contact embossing only on one edge and not having contact embossing on the other edge is used, that is, the secondary sheet according to the present invention. In the continuous sheet, each sheet in a laminated state is not fixed to an edge on which contact embossing is not provided. Therefore, even if wrinkles, distortions, or deflections occur due to misalignment between the sheets constituting the secondary continuous sheet, the misalignment can be corrected at the edge on the non-contact embossing side.

  In the production method of the present invention, at least one of the rolls around which the secondary continuous sheet is wound between the secondary fabric roll and the folded folded plate is used as a crown roll or an expander roll, and the crown roll or the expander roll. The above-mentioned secondary continuous sheet is supplied to the folded plate via The crown roll and the expander roll act so as to release wrinkles and strain deflection to the edge side in the process of conveying the sheet on the roll. In the secondary continuous sheet of the present invention, wrinkles and flexures can be released to the edge portion to which contact embossing is not applied. Therefore, in the stage where the secondary continuous sheet is supplied to the folded folding plate, the secondary continuous sheet has wrinkles and the like. It will not be.

  In addition, the crown roll and the expander roll are not used by the conventional manufacturing method. The reason is that in the secondary continuous sheet in order to ensure the fixing of each sheet, contact embossing was given to both side edges, so when adopting a crown roll or an expander roll, wrinkles occur in the vicinity of the contact embossing, Alternatively, the contact emboss is peeled off without allowing the deflection to escape.

  In the production method of the present invention, in particular, when the feeder roll immediately before the folded plate is a crown roll or an expander roll, a secondary continuous sheet having no wrinkles on the folded plate can be reliably supplied, so that the wrinkle prevention effect is enhanced.

  On the other hand, since the multi-stand type interfolder performs folding by guiding the edge of the secondary continuous sheet with the folding plate, in the manufacturing method of the present invention, contact embossing is provided only on one edge of the secondary continuous sheet. Since it is not provided, wrinkles, flexure, and distortion can be released even when the edge is guided by the folded plate, so that the occurrence of wrinkles on the folded plate is effectively prevented.

  Further, in the manufacturing method of the present invention, when the contact embossing at one edge of the secondary continuous sheet is intermittently formed along the edge, flexibility occurs in the joining of the secondary raw sheet by the contact embossing, and the crown roll Alternatively, the secondary continuous sheet is appropriately extended in the CD direction by the expander roll, and in particular, the effect of eliminating overlapping wrinkles extending in the MD direction is increased. In other words, by intermittently forming the contact embossing along the edge, a certain amount of wrinkles can be effectively released even at the edge on the contact embossing side, and a further effect of preventing wrinkles can be achieved. .

  In the production method of the present invention, it is desirable that the folded plate is folded so that the edge with contact embossing is on the upper side when the secondary continuous sheet is folded. If it does in this way, the tissue paper product of the said Claim 5 will be manufactured. The tissue paper product is free from wrinkles due to the manufacturing method, and the contact emboss is positioned at the edge of the tissue paper exposed from the take-out port particularly during use. That is, since the contact embossing is located at the edge of the side to be pulled out, the risk of ply peeling at the time of pulling out is significantly reduced.

  As described above, according to the present invention, in the method for manufacturing a pop-up type tissue paper product that manufactures a bundle with a multi-stand type interfolder, the second continuous sheet ridge when forming a bundle with the multi-stand type interfolder, Occurrence of bending and distortion is prevented, and the productivity and production speed of tissue paper products are improved. In addition, a tissue paper product free from wrinkles in the tissue paper constituting the bundle is provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the tissue paper product 1 according to the present embodiment is a storage in which a bundle 10 of tissue papers 11 in which a plurality of tissue papers 11 are folded and overlaid is formed with a take-out port 25 on the upper surface. It is stored in the box 2, and when one piece of the tissue paper 11 is taken out from the take-out port 25 at the time of use, a part of one piece of the lower layer laminated adjacently is exposed from the take-out port. It is configured.

In the method for manufacturing the tissue paper product 1 of the present embodiment, the bundle 10 of tissue paper 11 is manufactured by the multi-stand type interfolder 20.
The formation of the bundle 10 in the multi-stand type interfolder 20 according to this embodiment is performed as follows.

  First, as shown in FIGS. 2 and 3, a secondary raw roll 12 that is manufactured by a ply machine or the like and wound by laminating a plurality of continuous sheets is provided with a pair of folded plates 21 and 21. Each of the folding mechanism sections 22, 22... Is rotatably attached to each of the 20 original roll support sections 23 of a multi-stand type interfolder having a structure in which a large number (usually 80 to 120) of folding mechanism sections 22, 22. Then, the secondary continuous sheets 12A and 12B are fed out from the secondary raw roll 12.

  In the manufacturing method of the tissue paper product 1 of the present embodiment, as shown in FIG. 2, the secondary continuous sheet 12A (12B) wound as the secondary raw roll 12 has one edge in the width direction. The contact emboss 13 along the edge is provided only at the portion, and the secondary continuous sheet 12A (12B) is provided with no contact emboss at the other edge.

  Although the form of the contact embossing 13 is not particularly limited, it may be 1.0 to 10.0 mm in width and 5.0 to 25.0 mm from the edge along the edge, that is, along the longitudinal continuous direction. .

  In the present embodiment, the contact emboss 13 is continuously provided linearly, but may be provided intermittently. If it is provided intermittently, it is preferable to provide a continuous length in the MD direction of 0.5 to 5.0 mm and an interval of 3.0 to 30.0 mm. In particular, when intermittently formed in this manner, the portion of the secondary continuous sheet does not become hard due to the joining of the sheets by contact embossing, so that wrinkles and the like can be escaped more effectively.

  As shown in FIG. 3, the belt-like secondary continuous sheets 12A and 12B fed from the secondary web roll 12 are guided by guide rollers 24 and 24, etc., and the two sheets are folded together as a set. 22 is supplied.

  The folding mechanism unit 22 includes a pair of folding plates 21 and 21, and each secondary continuous sheet 12 </ b> A (12 </ b> B) guides the secondary continuous sheet to the folding plate for each folding plate 21. The rollers 25 and 25, the guide round bar members 26 and 26, and the feeder roll 27 are supplied. At this time, each secondary continuous sheet 12A (12B) is guided to the folded plate by the guide round bar members 26, 26 while being shifted in position so that the side end portions do not overlap each other.

  In the multi-stand type interfolder 20 according to the present embodiment, the guide rollers 24 and 25 are wound before the secondary continuous sheet 12A (12B) fed from the secondary raw roll 12 is supplied to the folded plate. At least one roll such as the guide round bar member 26 and the feeder roll 27 is a crown roll 28 or an expander roll 29 shown in FIG.

  As shown in FIG. 4 (a), the crown roll 28 has a substantially barrel shape in which the diameter of the central portion in the width direction is larger than the diameter of the side portion, and the expander roll 29 is shown in FIG. 4 (b). As shown in the figure, the side in contact with the sheet has a substantially bow-like shape, and all have the effect of releasing wrinkles, distortions, and deflections to the edge of the sheet.

  In the manufacturing method of this embodiment, when the secondary continuous sheets 12A and 12B pass over the crown roll or the expander roll, wrinkles, distortions, and deflections are released to both side edges and stretched.

  As shown in FIG. 5, since the secondary continuous sheet 12A (12B) according to this embodiment has a laminated structure, the sheet S1 on the side not facing the crown roll or the like faces the crown roll or the like. The sheet S2 is stretched so as to follow the sheet S2 on the side that is being processed. Therefore, wrinkles etc. can escape also at the edge portion on the side where the contact emboss 13 is provided. However, preferably, the crown roll or the like is in an aspect in which both sides of the secondary continuous sheet 12 </ b> A (12 </ b> B) are in contact with each other, and there are two or more from the secondary raw roll 12 to the folding plate 21 of the folding 22. It is desirable to provide it.

  In particular, in the present embodiment, the rolls that are preferably also wound immediately before the folded plate 21 and are simultaneously wound in a state where the secondary continuous sheets 12A and 12B are partially overlapped in the width direction. Is a crown roll or the like, and the wrinkles and the like of the respective secondary continuous sheets 12A and 12B supplied to the folding plates 21 and 21 are reliably stretched immediately before the folding plates 21 and 21.

  The crown amount L1 in the crown roll, the curvature rate in the expander roll, etc. are not particularly limited. It can be appropriately determined according to the width of the secondary continuous sheet, the paper thickness of the secondary continuous sheet, the basis weight, the softness, and the like.

  On the other hand, as shown in FIGS. 6 to 10, the secondary continuous sheet 12 </ b> A is stacked while being folded in a Z shape while the side ends of the pair of secondary continuous sheets 12 </ b> B are crossed with each other. .

  For each folded plate 21, as described above, the pair of continuous secondary continuous sheets 12A and 12B are guided by the guide round bar members 26 and 26 while being shifted in position so that the side ends do not overlap each other. The In the folded plates 21 and 21, the continuous secondary continuous sheet 12 </ b> A that overlaps the lower side at the time of the guidance is used as the first continuous secondary continuous sheet 12 </ b> A, and the continuous secondary continuous sheet that overlaps the upper side. Assuming that the sheet 12B is a second continuous secondary continuous sheet 12B, these continuous secondary continuous sheets 12A and 12B are the second continuous secondary continuous sheet 12B of the first continuous secondary continuous sheet 12A. The non-overlapping side end e1 is folded back to the upper side of the second continuous secondary continuous sheet 12B by the side plate 21e of the folding plate 21, and the first continuous secondary continuous sheet 12B is first continuous. The side end e2 that does not overlap the secondary continuous sheet 12A is folded downward so as to be drawn under the folding plate 21 from the slit 21s of the folding plate 21.

  At this time, the side end e3 (e1) of the continuous secondary continuous sheet 12A stacked while being folded in the upstream folding plate is guided between the folded portions of the second continuous secondary continuous sheet from the slit of the folding plate. Is done.

  In this way, the continuous secondary continuous sheets 12A and 12B are folded and the side edges of the adjacent continuous secondary continuous sheets 12A and 12B are overlapped with each other.

  Below each folding plate 21, there is located a continuous tissue paper bundle 10C that is stacked while being folded by a folding mechanism section 22 on the upstream side of the folding plate 21, and this folding mechanism section 22 is placed on the continuous tissue paper bundle 10C. The folded secondary continuous sheets 12A and 12B are associated and stacked. These continuous tissue paper bundles 10C are configured to be sequentially sent downstream by a conveyor. That is, as the folding mechanism portion 22 located upstream is moved to the folding mechanism portion 22 located downstream, the number of stacked tissue paper bundles 10C increases.

  In the manufacturing method of the present embodiment, as shown in FIG. 10, when the secondary continuous sheets 12 </ b> A and 12 </ b> B are folded back by the folding plates 21 and 21, the contact emboss 13 is given to the edge located on the upper side of the stack. I try to be an edge. In order to make the edge on the side where the contact embossing 13 is located on the upper side, contact embossing is applied to the secondary continuous sheets 12A and 12B in consideration of the paper run from the secondary raw roll 12 to the folded plates 21 and 21. What is necessary is just to determine suitably to which edge the contact embossing 13 is provided, when providing 13. Moreover, what is necessary is just to define the aspect at the time of setting the secondary original fabric roll 12 which wound up such secondary continuous sheet 12A, 12B to the original fabric roll support part 23 collectively.

  As described above, the continuous tissue paper bundle 10 </ b> C that is folded and folded by the folds 22, 22... Of the multi-stand type interfolder 20 has a predetermined interval in the flow direction at the downstream cutter unit of the most downstream folding mechanism unit 22. The tissue paper bundle 10 is cut (cut).

  The tissue paper bundle 10 formed by cutting in the cutting process is stored in the storage box 2 as a tissue paper product 1 as shown in FIG.

  In the multi-stand type interfolder 20 according to the present embodiment, the continuous tissue paper bundle 10C has a flow direction in the vertical direction (MD direction) and a horizontal direction (CD direction) along a direction orthogonal to the flow direction. Yes. For this reason, the direction of the paper of the tissue paper 1 constituting the tissue paper bundle 10 obtained by cutting the continuous tissue paper bundle 10C into a predetermined length is the extending direction of the folded portion of the tissue paper 11 as shown in the figure. Along the vertical direction (MD direction), and along the direction perpendicular to the extending direction of the folded portion of the tissue paper 11 (CD direction).

  Therefore, when the tissue paper product 1 manufactured according to the present embodiment stored in the storage box 2 as described above is pulled out of the tissue paper 11 from the storage box 2 as shown in FIG. Becomes along the horizontal direction (CD direction) of the tissue paper 11. Further, the bundle 10 is formed such that the edge of the tissue paper 11 to which the contact emboss 13 is applied is located on the upper side.

  Here, the manufacturing method of the secondary raw fabric roll 12 which concerns on this embodiment is also demonstrated. The secondary original fabric roll 12 around which the secondary continuous sheets 12A and 12B having the characteristic contact embossing aspect of this embodiment are wound can be manufactured by a ply machine 30 shown in FIG.

  The ply machine 30 according to the present embodiment can set two or more primary web rolls wound with the primary continuous sheets S1 and S2 that are single-layer crepe paper manufactured in the paper making process, and each primary web roll. The primary continuous sheets (S1 and S2 in the illustrated example) fed out from JR and JR are stacked along the continuous direction and supplied to the laminating unit 31 to form a laminated continuous sheet S3.

  In the subsequent stage of the laminated portion 31, contact embossing means 32 for providing contact embossing, slitting means 33 for slitting the laminated continuous sheet S3 to the width L2 of the tissue paper, and winding means 34 for winding the slit sheet are appropriately arranged in this order. Means are provided.

  The contact embossing means 32 includes a receiving roll 41, which is a metal roll or an elastic roll, and a metal-made hard roller 42 having a fine convex portion 42A on the surface, and abutting the outer peripheral surfaces with each other with a predetermined pressure. , Each is rotatably installed. Then, with respect to the portion corresponding to the center of the width L of the tissue paper in the laminated continuous sheet S3, lamination is performed between the convex portion 42A existing at a position near either one of the left and right edges and the receiving roll 41. By conveying the sheet while sandwiching the continuous sheet S3, a line-shaped contact emboss 13 for preventing delamination along the continuous direction is applied to a predetermined position of the laminated continuous sheet S3. In addition, what is necessary is just to determine suitably whether the position which provides this contact embossing 13 in any one of right and left with respect to a center part considers the paper run in the multi-stand type inter folder 20. By this selection, it is possible to select whether the edge to which the contact emboss 13 of the tissue paper 11 constituting the tissue paper bundle 10 is provided is the upper side or the lower side of the stack.

  The laminated continuous sheet S3 provided with the contact embossing 13 is then slit in the continuous direction by the slitting means 33 so as to be the product width of the tissue paper, and is taken up by the winding means 34 to be the secondary raw roll 12. The

  Using this secondary web roll and forming a bundle with the multi-stand type interfolder with the above-mentioned crown rolls etc. appropriately arranged, the secondary continuous sheet can be prevented from wrinkling, bending and distortion, producing tissue paper products. It is possible to improve the productivity and the production speed, and it becomes a high-quality tissue paper product with no defects in the tissue paper constituting the bundle.
