2. Description of the Related Art There are six narrow toilet paper rolls,
It is common to put 8, 12, 18, or the like as one unit, put them in a bag of synthetic resin film, pack them, and trade them. In recent years, the same pattern of different colors, different patterns of different colors, and different patterns of the same color are printed on the paper of one unit of a plurality of narrow width toilet paper rolls to attract consumers' interest. ing.

[0003] There are roughly two methods for producing a large number of narrow (usually 114 mm) toilet paper rolls from wide toilet paper.
As described in JP-B-56821, a wide-width toilet paper is wound on a winding shaft for a predetermined length to form a log roll of the toilet paper, and the log roll is removed from the winding shaft and described in Japanese Utility Model Publication No. 7-23197. A method of cutting a large number of toilet paper rolls of a predetermined narrow width with a log cutting device or the like, or a method of cutting the toilet paper roll into a predetermined narrow width while extracting from a winding shaft, the second method is a winding shaft After slitting a large number of narrow narrow toilet papers around a reel while slitting a wide width toilet paper running toward the machine into a plurality of strips of a predetermined narrow width by a slitter, pulling out from the reel, This is a method of making a large number of toilet paper rolls.

[0004]

For example, a different color pattern is printed on each paper surface of the toilet paper roll.
For example, in the case of packing 12 toilet paper rolls as one unit, conventionally, for example, a large number of toilet paper rolls in which a red pattern is printed on paper by one toilet paper winding device, and another blue pattern is printed on paper. Make 12 kinds of toilet paper rolls with many printed toilet paper rolls and many different patterns of different colors printed on paper in the same manner, and then collect and pack the 12 kinds of toilet paper rolls to one. Must.

[0005] Therefore, since one kind of 12 kinds of toilet paper rolls is produced, it takes time and trouble to exchange printing devices such as a printing cylinder and an ink container provided in the toilet paper take-up device, and productivity is increased. Bad, these 12
There is the inconvenience of storing one type of toilet paper roll for one type, and furthermore, a cumbersome operation of collecting one type of toilet paper roll for 12 types and manually packing the same is required.

FIG. 1A and FIGS. 2, 3, 4 and 5 are the same as those described in the above-mentioned JP-A-6-156821.
An apparatus for manufacturing a roll of toilet paper according to claim 1.
Shown, and 11 and 12 and the pair of parallel inlet side friction drive rolls in the winding position, a outlet-side friction drive roll, the winding axis 1 rests between the two friction drive roll, the two rolls 1
When both rolls are driven to rotate in the direction of the arrow by the contact frictional force with the rolls 1 and 12, they rotate in the direction of the arrow, pull out the wide toilet paper P from the raw fabric roll R on which the wide toilet paper is wound, and wind it around the periphery Take (FIG. 1A). During this winding, a rider roll 13 that idles from above comes into contact with the winding shaft 1 and is pushed up by the thickening of the winding layer of the paper wound on the winding shaft. In this embodiment, the rider roll 1
Numeral 3 is rotatably supported by a support frame 15 attached to an elevating member such as a piston cylinder 14 or a swing arm that swings vertically in the piston cylinder.

When the wide width toilet paper is wound on the winding shaft 1 for a predetermined length to form the log roll L, the friction drive rolls 11 and 12 are stopped as shown in FIG. 13 is retracted to the upper position, the kicker 2 pushes both ends of the winding shaft protruding from both ends of the log roll L placed between the pair of friction drive rolls 11 and 12, and sends out the log roll together with the winding shaft to the forward position, A reel for the next log roll is supplied between the pair of friction drive rolls 11 and 12 to ride on the paper, and the cutter 3 cuts the following paper between the reel and the advance position, and at the same time, The size liquid adheres to the trailing end of the paper of the log roll, and the air injection nozzle 4 injects air from below to the start of winding of the paper and turns the start of winding on the winding shaft as shown by a broken line, and the rider roll 13 Lower and press the beginning of the paper onto the reel. Roll 11 and 12 to start the rotation resume the winding of the next log roll.

In order to attach the size liquid to the tail of the log roll paper, an air cylinder 61 is attached to both ends of the cutter 3 with the pistons directed downward, and a glue string 62 is stretched between the lower ends of the pistons. When cutting the paper, both air cylinders extend the piston downward, and the well-known gluing device 60 presses the glue liquid contained in the glue string against the paper. The size liquid is contained in a gutter-like elongated container 63 traversing the paper,
This container can be advanced and retracted by the air cylinder 64, and is always at the position shown in FIG. When glue is applied, the air cylinder 61 moves the piston short and downward to immerse the glued cord 62 in the glue liquid in the container, and then the air cylinder 61 retracts the piston to put the glued cord into the container 63.

, The endless chain 9 is driven, the other end surface of the log roll L is pressed by the pusher 8 toward the tip 1a of the reel 1, and the log roll is pushed out from the tip of the reel. At this time,
The support rolls 5, 5 'are driven to rotate, and the log roll is rotated in one direction along with the winding axis, and the trailing end of the paper cut by the cutter is wound and adhered. It is preferable to press with. Further, a log roll L pushed out of the winding shaft by a pusher is sandwiched from above and below the leading end 1a of the winding shaft, and the drawing conveyors 10, 10 are driven in the direction of pulling out the log roll from the winding shaft in cooperation with the pusher. Is preferably provided. In this way, a log roll coming off the winding shaft is obtained, and this log roll is thereafter cut into a large number of toilet paper rolls of a predetermined narrow width by the above-described log cutting device or the like. Further, the winding shaft remaining at the advance position is removed from the yoke member 7 before the next log roll is turned to the advance position, and waits for supply to the winding position. The pusher also returns close to the yoke member before the next log roll is turned to the forward position.

FIG. 1 (B) shows a log roll L pulled out from the winding shaft 1, and a broken line C shows a log roll made into a large number of narrow toilet paper rolls TPR. Indicates the cutting position to be cut. The width of one narrow toilet paper roll is fixed as described above, and is, for example, 114 mm. This is illustrated in FIG.
As shown in FIG. 2C, the log roll L is cut on the wide-width toilet paper P traveling toward the reel because the reel 1 is pulled out from the raw roll R and wound by the rotation of the reel 1. Cutting position C 'when the cutting is performed, and narrow strip-shaped rows I and I which become individual toilet paper rolls TPR.
I, III... N-1, n means that they are known in advance as indicated by the broken lines.

For this reason, on the path of the wide toilet paper P traveling toward the winding shaft 1, one of the narrow strip-shaped rows is placed.
A printing device 20 that prints a different color pattern, or a different pattern of the same color, or a different pattern of the same color for one or a plurality of addresses can be arranged across the rows.

In the embodiment shown in the drawing, the printing apparatus 20 has a trough-shaped ink container 21 containing printing ink, and immerses a part of the outer periphery in the ink in the ink container, and contacts and adheres to toilet paper. And a plate cylinder roller 22 for printing by applying the applied ink to the toilet paper. The plate cylinder roller 22 has the same peripheral speed as the traveling speed of the wide toilet paper P and the same arrow direction as the traveling direction. It is driven to rotate in the direction.

FIG. 1C shows a part of a wide toilet paper P which travels in the direction of the arrow to be wound around the winding shaft 1 and becomes a log roll L. The left side of three rows I, II and III Below, a printing device 20 that prints, for example, a different pattern of red is arranged in each row across the three rows, a red A pattern in row I, a red B pattern in row II, and a row B in row III. Prints a red C pattern with the plate cylinder roller 22. Then, below this red and the two columns IV and V on the right side with respect to the patterns A, B and C,
A printing device 20 that prints, for example, a different pattern of blue, which is a different color, is arranged in each row across the two rows, and a blue D
On the pattern, row V, a blue E pattern is printed by the plate cylinder roller 22,
Intermediate column to the bottom two rows n-1, n of the right side is omitted, across the two rows, for example, to place the printing device 20 for printing a green pattern is unique, column n-1 print the same color B pattern in the same color a pattern, column n is the, under the column X of the left adjacent column n-1, across the column, for example, to print a yellow pattern unique The printing device 20 is arranged, and the yellow pattern F is printed by the plate cylinder roller 22.

As a result, if one log roll L is cut by a log cutting device to obtain, for example, 12 narrow toilet paper rolls, the individual paper surfaces of the 12 toilet paper rolls have different colors. Pattern and the same pattern,
Since different patterns of the same color are printed, the twelve toilet paper rolls may be packed in one bag.

Also, as described in paragraph 0015, a different roll of a different color, or a log roll having the same pattern or a different pattern of the same color printed on a paper surface, while pulling the log roll from the winding shaft as described above,
The toilet paper roll may be formed by cutting the toilet paper roll with different patterns or patterns of the same color or different patterns of the same color printed on a circle by a broken line C in FIG. 1B, and the 12 toilet paper rolls may be packed in one bag. .

FIG. 6 shows an embodiment according to claim 2, and FIG.
In this embodiment, the winding device used in both embodiments is almost the same as that shown in FIG. 1 (A), and the difference is that the winding device is pulled out from the raw material roll R and wound around the winding shaft 1. Before the wide toilet paper P traveling to be taken out reaches the reel,
A known slitter 16 composed of a rotating upper blade 17 and a lower blade 18 slits into a number of strips of a predetermined narrow width (usually 114 mm), and the winding shaft is a slit of a number of narrow strips of toilet paper. The reels are wound adjacent to each other for a predetermined length. The position where the slitter 16 slits the wide toilet paper P in the width direction is such that when the slit narrow strip-shaped toilet paper is individually wound on the winding shaft 1 for a predetermined length and then pulled out from the winding shaft, the individual toilet paper is removed. As described in paragraph 0012, at the position that becomes the Parole TPR, the position is known in advance.

Therefore, instead of the wide toilet paper, a large number of strip-shaped toilet papers slit by a slitter are wound adjacently on the winding shaft 1 as described in paragraphs 0007 to 0011, and the cutter 3 is cut. When the rear part of the paper is wound and glued, the entire paper winding body is pushed out from one end of the winding shaft by pushing with the pusher 8, and the paper winding body becomes an individual narrow toilet paper roll TPR.

In the second aspect (FIG. 6), the slit is slit by the slitter on the path of the wide toilet paper P traveling toward the slitter, in front of the slitter 16, to form a plurality of narrow strips of toilet paper. I, II, I
II ... one of n-1 and n, or a different pattern of a different color, or the same printing apparatus 20 for printing the same pattern or a different pattern of the same color as shown in FIG. Place it across.

According to a third aspect of the present invention, the strip of toilet paper PI, PII, and PII is slit on the path of a large number of narrow strips of toilet paper that are slit and run adjacent to the winding shaft. PIII... The same printing device 20 as shown in FIG. 1 for printing a different color pattern, the same pattern, or the same color different pattern for one or more of Pn−1 and Pn.
Is placed under the belt-shaped toilet paper.

The printing apparatus 20 prints the colors and patterns (FIG. 6B) to be printed on the columns I, II, III... N-1, n to be the belt-shaped toilet paper according to claim 2, and the belt-shaped toilet paper PI, PII, PIII ... Pn-1, P
n and the color or pattern (FIG. 7B) to be printed on paragraph n for convenience.
015 is the same as FIG. 1C of claim 1.

[0023] With this arrangement, the reel is wound adjacent to a predetermined length of the reel, and then pushed by a pusher 8 so that the whole is wound from one end of the reel.
For example, each of the narrow toilet paper rolls from which twelve were punched out is printed with a different color pattern, the same pattern, and a different pattern of the same color, so that the 12 toilet paper rolls can be packed in one bag. Good.

In the above-described embodiments of the present invention, for example, different patterns of the same color, different patterns of the same color, different patterns of the same color are printed on all 12 toilet paper rolls,
There was no same pattern of the same color as one, but different patterns of the same color and the same pattern, six kinds of different patterns of the same color were printed, and out of 12 toilet paper rolls, two of the same patterns of the same color were printed. Toilet paper rolls having the same color and the same pattern printed thereon may be mixed in one bag, or printing may not be performed on the paper surface of some toilet paper rolls. May be mixed in one bag.

Although the printing apparatus 20 is shown as being soaked, it is not limited to this. For example, an inking roller made of rubber or the like is immersed in ink in an ink container, and a part of the outer periphery is immersed. The plate cylinder roller may be in contact with the roller and the toilet paper, and the ink that has reached the surface of the inking roller may print on the toilet paper via the plate cylinder roller.

FIGS. 1 (C), 6 (B), and 7 (B)
In FIG. 8, the printing apparatuses 20 adjacent to each other in the width direction of the wide toilet paper are arranged so as to be shifted back and forth with respect to the traveling direction of the toilet paper. For example, as shown in FIG. I, II, III
Also, an ink container 21R containing red ink is provided below three strip-shaped toilet papers PI, PII, and PIII on the left side slit by a slitter, and two rows IV on the right thereof.
V and two zonal toilet papers PIV and PV on the right
Below is an ink container 21B containing blue ink, and the middle is omitted, and two rows of n-1 and n on the right and green ink are placed under the two band-shaped toilet papers Pn-1 and Pn on the right. Under the ink container 21G, the row X on the left side thereof, and the belt-like toilet paper PX on the left side, ink containers 21Y containing yellow ink are arranged in a straight line in the width direction of the toilet paper. The body roller 22 has adjacent portions of the ink containers 21R and 21B, and the ink containers 21Y and 21B.
An annular groove 22 'straddling the adjacent portion of G is provided, and a part of the outer periphery of a portion of the plate cylinder roller separated by the annular groove 22' is immersed in the ink containers 21R, 21B.
A different color pattern, a different pattern, or a different color pattern may be printed by the plate cylinder roller in the same manner as described in paragraph 0015. In the case where the inking roller immerses a part of the outer periphery in the ink container, an annular groove is provided in the inking roller so as to straddle the adjacent portion of the ink container, so that one plate cylinder roller provides a different color pattern. And different patterns of the same color and the same color can be printed.

In addition, the individual ink containers containing the different colors of ink as described above are not arranged in a straight line in the width direction of the toilet paper, but are elongated in accordance with the width of the toilet paper.
Place two ink containers in the width direction of the toilet paper,
The inside of the ink container may be partitioned by a plurality of partition plates so that inks of different colors are charged. In that case, 1
An annular groove straddling each partition plate is provided on a plate cylinder roller or a single inking roller, and a part of the outer periphery is immersed inside each of the partition plates, thereby similarly forming a different color pattern or the same. A pattern and a different pattern of the same color can be printed by one plate cylinder roller.

[0028]

As is apparent from the above, according to the present invention, a plurality of narrow toilet paper rolls manufactured by winding on a single reel have different colors and different patterns on the paper surface. Since a different pattern of the same color can be printed, a toilet paper roll having various types of colors and patterns on paper can be packed in one bag by directly packing the bag. This saves labor and time for replacing the printing device installed in the winding device as in the related art, and stores toilet paper rolls separately for each of various types of patterns, and stores various types of paper stored at the time of bag filling. Eliminates the task of collecting one or several toilet paper rolls and putting them in a bag.
