Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a portable bag-packed tissue paper and a method for manufacturing the same.

<Conventional technology> The conventional portable bag bag 38 is
As shown in the figure and FIG. 13a, the rectangular or square tissue piece 35 is folded into five pieces parallel to the upper side, and then folded into two pieces parallel to the side edge, and an appropriate number of tissue pieces are folded in this way. They are stacked and packaged. There is also one that has seven parallel folds along the upper side. Furthermore, the bagged tissue 38 is provided with parallel notches on its long sides, which form a closing portion 37.

In addition, although the conventional method for manufacturing the bag-filled tissue paper 38 is shown in FIG. 14, a device for folding and cutting roll-shaped base paper is described, for example, in Utility Model Registration No. 1212301 (Utility Model No. 1212-24018). There is.

In FIG. 14, 51 is a tissue base paper roll, and the tissue base paper 52 is guided by guide rollers 53, 54, 56, and 58, and vertical folding guide plates 55, 57 suitably move the tissue paper in the flowing direction. A parallel vertical fold is made.
Further, the vertically folded tissue base paper is alternately folded into the tissue paper 5 by two rollers 60, 60.
By gripping and releasing 2, the tissue base paper is folded into a meander 61 and cut by a cutter 62 (see Utility Model Publication No. 52-24018). In this way, the folded tissue piece 35 shown in FIG. 12a is completed.

The folded tissue pieces 35 are then manually stacked in an appropriate number (not shown), and finally wrapped by a pillow-type packaging machine to form the bagged tissue pieces 38.
is completed.

<Problems to be Solved by the Invention> The tissue pieces of the conventional bagged tissue paper 38 follow the folds as shown in FIG. 13a.
Because it is folded in five parallel to the top side, and
Because the tissue pieces are thin and flexible, it takes a lot of effort to unfold them all, and in some cases,
In some cases, the outermost fold was left unopened and used.

In addition, as shown in FIG. 12b, the drawer edge 36
Since the direction is parallel to the opening 37 provided parallel to the long side of the bagged tissue paper 38,
The direction of the horizontal fold 39 is perpendicular to the opening 37.
Therefore, there was a drawback that there was some resistance when grasping the drawer edge 36 and pulling it out from the opening 37.

On the other hand, in the conventional manufacturing method for bagged tissue paper, there is a process of vertically folding the tissue paper, followed by a horizontal folding process, the folding process is completed first, and then there is a cutting process, and this process is automated. However, the process of stacking a certain number of cut tissue pieces on a conveyor leading to a packaging machine was performed manually.

In addition, in the above manufacturing method, the horizontal folding method involves folding the vertically folded paperback paper into a zigzag and cutting it in the center.
Horizontal folding can only be done by two folds, and therefore, in order to produce a bag-filled bag of a certain size, it is necessary to fold the bag five times or more at the vertical folding stage.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a bag of tissues in which tissue pieces can be easily pulled out from the bag, and in which the pulled-out tissue pieces can be easily unfolded.

Furthermore, the present invention provides a cutting step between the vertical folding process and the horizontal folding process of the tissue base paper, and after cutting the vertically folded tissue base paper into a predetermined length,
A horizontal folding process has been installed, making it possible to perform horizontal folding multiple times.Furthermore, the stacking process on the conveyor leading to the packaging process is fully automated, and the entire process from tissue paper base paper to finished tissue paper in bags is fully automated. The purpose is to do something.

<Means for solving the problem> The folding of the tissue piece according to the present invention is carried out by the first method.
As shown in Figure 3b, compared to the conventional tissue piece in Figure 13a, the folding is parallel to the upper side (vertical folding).
On the other hand, the number of folds (horizontal folds) parallel to the sides is increased to facilitate the unfolding of the tissue pieces, and the bag tissue 26b is folded parallel to the long sides of the bag tissue 26b as shown in FIG. 10. The direction of the provided opening and the drawer edge 31 of the tissue piece 16
Since b are perpendicular, the horizontal fold line 40 of the tissue piece shown in FIG. 13b becomes parallel to the direction of the opening, making it easier to pull out the tissue piece.

In addition, the method for manufacturing bagged tissue paper according to the present invention includes the following steps: first, vertically folding the tissue base paper parallel to the flow direction of the tissue paper base paper; cutting the vertically folded tissue paper base paper into tissue pieces; A process of horizontally folding the folded and cut tissue pieces multiple times using a plurality of suction drums, and a process of stacking an appropriate number of folded tissue pieces on a conveyor headed for the packaging process via a rotary conveyance device. and the process of packaging the layers of tissue pieces are all automated and performed continuously. This makes it possible to completely automate the conventional manual work and manufacture the bagged tissue paper mentioned above.

<Example> An example will be described below based on the drawings. FIG. 1 is an explanatory diagram of the process from the vertical folding process of tissue paper to the process of feeding the folded tissue pieces onto a conveyor headed for a packaging machine. Tissue base paper 2 pulled out from a roll 1 of Tissue base paper by an extrusion roller 9 is guided to a first vertical folding plate 5 by guide rollers 3 and 4, and one side of Tissue base paper 2 is aligned in the flow direction of the Tissue base paper. It is folded in half lengthwise. The tissue base paper 2 is moved to a second vertical folding plate 7 by a guide roller 6.
The other side is then folded in half lengthwise. Therefore, as shown in FIGS. 6 and 7, in the vertical folding, the upper and lower sides are folded in opposite directions to form an S-shape.

The tissue base paper 2 which has completed the vertical folding process is led to an extrusion roller 9 via a guide roller 8 and is clamped. The tissue base paper 2 that has been clamped and pushed out by the pushing rollers 9 is guided to a rotary cutter 11 via a guide roller 10. The cutter 11 includes a suction roller 11a with a square bar 11c embedded therein and a roller 11b with a plate 11d attached thereto.

A first suction drum 12 for horizontal folding is adjacent to the cutter 11;
A second suction drum 15 is arranged in parallel. In addition, a first guide rod 13 is located directly below the closest position between the cutter 11 and the first suction drum 12, and a second guide is located directly above the closest position between the first suction drum 12 and the second suction drum 15. A rod 14 is provided.

The tissue piece 16 cut into a predetermined size by the cutter 11 is folded horizontally into two by the suction roller 11a, the first suction drum 12, and the first guide bar 13, as shown in FIG. .

That is, the tissue piece 16 remains attached to the suction roller 11a that rotates clockwise while moving toward the first guide rod 1.
Rotate to a position past 3 (Figure 11a). When the central portion of the tissue piece 16 reaches the first guide rod 13, suction by the suction roller 11a is stopped, and conversely, suction by the first suction drum 12 is started to move the tissue piece 16 from the center to the rear end. is attracted to the first suction drum 12 rotating counterclockwise, and rotates with the first suction drum 12 (FIG. 11b). Then, the suction roller 11 of the cutter
The portion of the tissue piece 16 that has gone beyond the first guide rod 13 while still attached to the section a returns along the first guide rod 13, and the tissue 16 is folded horizontally in half (FIG. 11c).

Although not shown, the tissue piece 16 that has been folded in two is similarly folded into four.

That is, the tissue piece 16 folded in half is
The second guide rod 14 remains attached to the suction drum 12.
Rotate to a position past . When the central portion of the tissue piece 16 reaches the second guide rod 14, suction by the first suction drum is stopped, and conversely, suction by the second suction drum 15 is started to move the tissue piece 16 from the central portion to the rear end. is attracted to the second suction drum 15 rotating clockwise, and rotates with the second suction drum 15. Then, the part that adheres to the first suction drum 12 and goes beyond the second guide rod 14 returns along the second guide rod 14, and the tissue piece 16
is further folded in half, and eventually folded horizontally into four.

Here, the operation of the cutter 11 is adjusted so that after cutting the tissue piece 16, the next cutting operation is performed after the cut tissue piece 16 reaches the second suction drum 15. The feed of the paper sheet 2 will be carried out intermittently.

When folding the tissue piece 16 into three horizontally as shown in FIG. 1 Suction of the suction drum 12 is started. The second guide rod 14 is located directly below the position closest to the first suction drum 12 and the second suction drum 15. The second suction drum 15 is rotated counterclockwise, and when the folded portion of the tissue piece 16 passes the second guide rod 14, the second suction drum 15 is rotated counterclockwise.
What is necessary is to stop suction by the suction drum 12 and start suction by the second suction drum 15.

The tissue piece 16 which has been folded horizontally into four is clamped and pressed by the second suction drum 15 and the roller 17.

The first suction drum 12 has a suction roller 11a.
A groove 12a is provided into which the protruding portion of the square rod 11c embedded in the groove 12a is inserted.

The tissue piece 16 folded into four is the second

It is sent to a chain conveyor 19 heading toward a packaging machine. As shown in FIG. 4, the conveyance device 18 has a cylindrical body 21 having flanges 20 at both ends, and a plurality of angular protrusions 22 arranged in two rows around the cylindrical body 21. The two rows of protrusions 22 are provided at opposing positions, and the paired protrusions 22 serve as forks to successively scoop out the four-fold tissue pieces 16 attached to the second suction drum 15. The scooped tissue piece 16 is rotated counterclockwise and sent to the conveyor 19 by the guide plate 23. The guide plate 23 is fixed to a conveyor frame or the like. conveyor 1
9 moves intermittently and prints a predetermined number of tissue pieces 16.
Once loaded, they head to the packaging machine one by one. Directly or indirectly read the rotation speed of the shaft of the cylindrical body 21,
A predetermined number of folded tissue pieces 16 are stacked on a conveyor 19.

The second suction drum 15 has two annular grooves 25 into which the tips of the groups of projections 22 fit.

A guide wheel 24 that rotates clockwise is provided diagonally below the rotary conveyance device 18, and the tissue piece 16 scooped up by the pair of protrusions 22 is set at a predetermined position by the guide wheel 24.

Another embodiment of the rotary transport device 18 is shown in FIG. This device has no collar and has two rows of protrusions 2.

Seal in the center longitudinal direction. Finally, the sheet containing the wet tissue is sealed and cut in the transverse direction to form a single bag.

In the case of dry tissue, a long sheet is created in a separate process with perforations that form the openings of the bagged tissue, and then wrapped in the same way as wet tissue. do. As another method, there is a method in which the perforation is not provided, and the seal is partially performed in the longitudinal direction at the center of the back surface to form an opening in an unsealed state from the beginning.

A tissue piece 16 folded by the manufacturing method of the present invention is shown in FIGS. 6 and 7,
The developed view of the tissue piece 16 in Fig. 6 is Fig. 13b.
The bagged tissue after packaging is shown in FIG. The part indicated by the dashed line in FIG. It is provided parallel to the fold line 40. Therefore, the drawer edge 31 of the tissue paper is perpendicular to the opening.

In the case of wet tissue, FIG. 8 is an exploded perspective view of the bagged tissue 26a completed through the packaging process. The bagged tissue 26a is provided with an opening in the shape of a U-shaped notch 27 and hook-shaped notches 28 extending from both ends thereof. The curved portion of the U-shaped cut 27 is partially discontinuous. When the label 29 is turned over, the tongue piece 30 surrounded by the cut 27 is peeled off while remaining adhered to the label 29, forming an opening, as shown in FIG. The tongue piece 30 cannot be completely separated from the bag body and is connected to the bag body, and the tongue piece 30 is attached to the label 2.
It plays the role of preventing complete peeling of No.9.

Further, the tongue piece 30 is provided vertically and parallel to the long side of the bagged tissue paper 26a, and as in the case of dry tissue paper, the horizontal fold is parallel to the tongue piece, making it easy to take out the tissue paper. ing.

<Effects> Since the manufacturing method of the present invention requires fewer vertical folds,
The vertical folding process can be simplified, and by placing the process of cutting the staple paper immediately after the vertical folding process, it becomes possible to easily perform horizontal folding multiple times using multiple suction drums, and further, The process of stacking folded tissue pieces on a conveyor leading to the packaging process, which was conventionally done manually, has been automated using a rotary conveyance device. Therefore, it is possible to continuously automate the entire process from the tissue paper base to the production of the finished tissue in bags.

In addition, in the bagged tissue produced according to the present invention, the number of vertical folds of the folded tissue pieces is small, that is, the fold width is wide, so that the tissue pieces can be easily unfolded. .

We were able to reduce the number of vertical folds by
This is because the horizontal fold can be increased from the conventional two-fold to three-fold or four-fold. Furthermore, by making the direction of horizontal folding parallel to the opening of the bagged tissue, the tissue piece can be easily pulled out without getting caught in the opening.

As described above, the present invention can automatically and continuously manufacture bagged tissue paper from the vertical folding process to the packaging process, and has a significant practical effect. Furthermore, the bagged tissue produced by this production method is much easier to use than conventional ones.
