It is a block diagram of 10. In FIG. 2, 4R and 4R are rolls of surface material, both of which are supplied to the press section 60 through the water-repellent adhesive application section 20 via the known joint section 9a. There is. The joining portion 9a is a device that connects the leading end of the remaining surface material sheet 4S to the tail end when one of the surface material sheets 4S is fully fed. Therefore, the surface material sheet 4S is always supplied during operation.

The water-repellent adhesive coating section 20 is composed of a plurality of known nozzles. This nozzle applies the water-repellent adhesive 8 to the surface material sheet 4S,
The back surface material sheet 4S is arranged in multiple rows in the width direction, and the water-repellent adhesive 8 can be applied in multiple rows in the width direction of the back surface sheet 4S. The water-repellent adhesive 8 is applied to each part of the backing material sheet 4S, which will be the peripheral portion of the sanitary article 1, by the nozzles, which will be described in detail later. The water-repellent adhesive 8 having water repellency can be used without particular limitation as long as it is an adhesive such as water-repellent hot melt. Furthermore, in the water-repellent adhesive application section 20, the water-repellent adhesive 8 is attached to the surface material sheet 4S by a nozzle in the figure, but the water-repellent adhesive 8 is attached to the surface material sheet 4S by a transfer roll. You may. 5R and 5R are original rolls of the absorber, both of which are adapted to be supplied to the cutting portion 30 via a known joint portion 9b. Reference numerals 6R and 6R are raw material rolls of the back surface material, and are both supplied to the polymerizing section 50 through the adhesive applying section 40 via the known joint section 9c. The adhesive application section 40 applies the adhesive 3 to the back surface material sheet 6S.

As shown in FIGS. 2 and 3, in the multi-row manufacturing apparatus 10 for sanitary products of this embodiment, first, the water repellent adhesive is applied to the surface material sheet 4S fed from the raw material roll 4R of the surface material. A water repellent adhesive applying step 20P for applying 8 is performed. On the other hand, the cutting step 30P for die-cutting the absorber 5 from the absorbent body sheet 5S that has been fed from the raw material roll 5R of the absorber, and the adhesive 3 on the surface material sheet 6S that has been fed from the raw material roll 6R of the surface material. Adhesive application step 40P for applying is performed respectively. And polymerization process 50P
Then, the absorber 5 is superposed on the adhesive 3 on the backing material sheet 6S. Then, the backing material sheet 6S and the front body sheet 4S sandwiching the absorber 5 are provided with the feed belt 59S.
It is sent by and is pressed from above and below so that the position does not shift in the pressing process 60P. Then, the back surface material sheet 6S and the surface material sheet 4S around the absorber 5 are subjected to a heat sealing step.
It is heat-sealed by 70P and sent by the feed belt 79. Finally, the sheet in which the surface material sheet 4S, the absorber 5 and the back surface material sheet 6S are laminated is the product cutting step 80.
Die-cut with P to become sanitary product 1.

FIG. 4 is a side view of the cutting section 30 and the overlapping section 50, FIG. 5 is an enlarged perspective view of the cutting section 30, and FIG. 6 is a sectional view of the die-cut roll 32. As shown in FIG. 4 and FIG. 5, the cutting unit 30 has an anvil roll 31 and a die-cut roll 32 arranged to face each other, and the absorber sheet 5S is fed between them. Details of the cutting unit 30 will be described later. The overlapping section 50 is a cutting section
A feed roll 51 is arranged so as to face the die-cut roll 32 of 30, and a holding table 52 is arranged so as to face the feed roll 51. The back surface material sheet 6S is sent to the upper surface of the pressing table 52, and the absorber 5 is sequentially superposed on the back surface material sheet 6S. Reference numeral 40 denotes an adhesive application section, which is configured by a known nozzle and applies the adhesive 9 to the back surface material sheet 6S at equal intervals. In the present embodiment, the diameter of the feed roll 51 is set to the die-cut roll.
By setting the peripheral speed to be larger than the diameter of 32, the peripheral speed thereof is set to be higher than that of the die-cut roll 32, the reason for which will be described later.

As shown in FIG. 5, on the roll surface of the die-cut roll 32, a sanitary product type cutter blade is provided.
33 is formed, and the cutter blade 33 is formed with as much space d as possible in the circumferential direction. Moreover,
The cutter blades 33 are arranged on the peripheral surface of the die-cut roll 32 in a plurality of rows in the width direction of the roll (two rows in the figure).
They are mounted side by side. And cutter blade
A large number of suction holes 34 are formed on the roll surface surrounded by 33.

Referring again to FIG. 4, θ1 is the suction area of the die-cut roll 32, which corresponds to the rotation angle from when the absorber 5 is cut from the absorber sheet 5S to when it is delivered to the feed roll 51. θ2 is a suction region of the feed roll 51, and corresponds to a rotation angle from when the absorber 5 is delivered to the feed roll 51 to when it is pressed against the pressing table 52. The mechanism that applies a negative pressure between the suction regions θ1 and θ2 is the first and second suction mechanisms, respectively.

The number N of rows of the cutter blades 33 in the die-cut roll 32 is not limited to two rows but may be any number of rows. However, the larger the number, the more sanitary articles 1 can be produced within a certain period of time. Therefore, it is suitable for mass production. Of course, the width of the absorber sheet 5S may be determined according to the width of the die-cut roll 32. If the number N of rows of the cutter blades 32 in the die-cut roll 32 is large, the width of the absorber 5S is widened, If the number N is small, the width of the absorber sheet 5S may be narrowed. Furthermore, it is preferable to insert the sponge 35 into the cutter blade 33 for the following reason. FIG.
As shown in, the sponge 35 is put in the part surrounded by the cutter blade 33, and this sponge 35 also has a suction hole.
34 are formed. When this sponge 35 is put, it has the following advantages. When the absorber sheet 5S is fed between the anvil roll 31 and the die-cut roll 32 shown in FIG. 5, the absorber 5 is cut from the absorber sheet 5S. When the absorber sheet 5S is cut, the absorber 5 is cut. Even if the cutter blade 33 tries to fit in the cutter blade 33, the sponge 35 pushes it back, so that the cutter blade 33 does not get stuck and cannot be taken out. Conversely, while being sucked,
Since a negative pressure acts through the suction hole 34 of the sponge 35, the inconvenience of being firmly sucked and dropping on the way does not occur.

Next, the first and second suction mechanisms will be described. However, since both are substantially the same, the second suction mechanism applied to the feed roll 51 of the superposition processing section 50 in FIGS. 7 to 8 will be described first. A large number of suction holes 54 are formed on the surface of the feed roll 51,
A duct 55 communicating with each suction hole 54 is formed in the feed roll 51, and the duct 55 is opened at one side wall of the feed roll 51. A fixing plate 56 is attached in close contact with the side wall of the opening of the duct 55, a duct 57 is formed on the fixing plate 56, and a vacuum pump 58 is connected to the duct 57. The duct 57 is formed to be long in the circumferential direction, and is formed in an angular range corresponding to the suction area θ2. With this configuration, the polymerization processing section
While the feeding roll 51 of 50 rotates, it performs the suction action only within the range of the angle region θ2, and returns to the atmospheric pressure outside the angle region θ2, and the negative pressure does not act. The first suction mechanism of the die-cut roll 32 has substantially the same structure as the second suction mechanism, and the suction hole 34 is formed by the cutter blade.
The only difference is that it is formed in the area surrounded by 33. Furthermore, the width of the feed roll 51 of the superposition processing section 50 may be determined according to the width of the die cut roll 32.

With the above structure, the cutting section 30 and the overlapping section 50 operate as follows. 9A and 9B are explanatory views of the action of the cutting unit 30 and the overlapping unit 50, FIG. 9A is a plan view of the absorber sheet 5S, and FIG. 9B is a plan view of the backing material sheet 6S. As shown in FIGS. 4 and 9, the absorber sheet
The 5S is fed between the anvil roll 31 and the die-cut roll 32 of the cutting unit 30, and here the absorber 5 is die-cut from the absorber sheet 5S in multiple rows in the width direction of the absorber sheet 5S. At this time, as shown in FIG. 9 (A), the gap d1 between the absorbers 5 is the same as the gap d between the cutter blades 33 shown in FIG. 5, and the gaps are very small. This is preferable because the material of the sheet 5S is not wasted. As shown in FIG. 4, the cut absorber 5 is sucked and sent in a negative pressure region of the rotation angle θ1 as the die cut roll 32 rotates, and when it comes into contact with the feed roll 51 of the superposition processing section 50, the die cut roll 32 The negative pressure on the side disappears, and the negative pressure is sucked by the feed roll 51 to be delivered to the feed roll 51. The absorber 5 is fed from here by the feed roll 51. The peripheral speed of the feed roll 51 is a die-cut roll.
Since it is higher than the peripheral speed of 32, the spacing d2 between the adjacent absorbers 5 is widened each time it is delivered. Then, when the feed roll 51 is rotated by the rotation angle θ2 while maintaining the widened distance d2, the absorber 5 is sent to a position facing the presser table 52, and the backing material sheet 6S is sent on the presser table 52. Pressed against. The adhesive 9 is applied to the back surface material sheet 6S by the nozzle of the adhesive applying section 40 in the previous step. Therefore, every time the absorber 5 is pressed onto the backing material sheet 6S on the presser table 52, the absorbent body 5 shown in FIG.
As shown in FIG. 5, the absorbers 5 in each row are bonded to the back surface material sheet 6S via adhesives in multiple rows in the width direction of the back surface material sheet 6S.

Next, as shown in FIG. 2 again, the front surface material sheet 4S and the back surface material sheet 6S are sent to the press section 60 via the feed belt 59 while sandwiching the multiple rows of the absorbers 5.
The press portion 60 is provided to prevent positional displacement of a portion that is to be heat-sealed by a heat-sealing portion 70 described later.
This press section 60 is composed of a pair of flat rolls,
The surface material sheet 4S and the back surface material sheet 6S with the multiple rows of the absorbers 5 sandwiched therebetween are sandwiched between the pair of flat rolls and pressure-bonded. Then, the front surface material sheet 4S and the back surface material sheet 6S that are pressure-bonded so as not to shift the absorber 5 are sent to the heat seal part 70 while sandwiching the multiple rows of the absorbers 5.

FIG. 10 shows a heat seal roll 71 of the heat seal portion 70.
2 is a schematic perspective view of FIG. As shown in the figure, the heat seal 70
Is composed of a pair of heat-sealing rolls 71. The surface material sheet 4S and the back surface material sheet 6S with the multiple rows of the absorbers 5 sandwiched therebetween are sandwiched between the heat-sealing rolls 71, 71 to generate heat. Sealed. Each of the pair of heat-sealing rolls 71 has multiple rows in the roll width direction, and sanitary article-type non-heating portions 73 are provided at equal intervals in the roll circumferential surface direction. The non-heating portion 73 is a recess formed slightly larger than the absorber 5 so that the absorber 5 is not thermally deteriorated by the heating portion 72 described later. The portion of the roll peripheral surface portion of the pair of heat-sealing rolls 71 excluding the non-heating portion 73 is a heating portion 72, and the front surface material sheet 4S and the back surface material sheet 4S.
It is for melting 6S and heat sealing. The roll width of the heat seal roll 71 may be determined according to the width of the surface material sheet 4S or the back surface material sheet 6S that is sent,

With the above structure, the pair of heat seal rolls 71 can heat seal the front material sheet 4S and the back material sheet 6S as follows. When the pair of heat seal rolls 71 of the heat seal unit 70 rotate, the heating units 72 and the non-heating units 73 of the respective heat seal rolls 71 are alternately overlapped with each other. When the heating units 72 are overlapped, the peripheral portions of the absorbers 5 in each row of the back surface material sheet 4S and the back surface material sheet 6S are melted, and the back material sheet 4S and the back material sheet 6S are melted.
And can be heat sealed. Further, when the non-heated portions 73 are overlapped with each other, the absorbers 5 in the respective rows are not heated by the non-heated portions 73.
Since the absorbers 5 in each row are located in the concave portions of the heat seal roll 71, they are not sandwiched between the heating portions 72 of the heat seal roll 71 or thermally deteriorated. Each time the pair of heat-sealing rolls 71 of the heat-sealing portion 70 are rotated, the heating portion 72 and the non-heating portion 73 are alternately overlapped with each other, and the above-described operation is repeated. Therefore, the front surface material sheet 4S and the back surface material sheet 6S are heat-sealed one after another.

FIG. 11 is a plan view of the surface material sheet 4S after passing through the heat seal roll 71. Of course, absorber 5
Are arranged in multiple rows in the width direction of the surface material sheet 4S,
Since the respective absorbers 5 are substantially the same as each other, only the peripheral portion of one absorber 5 is illustrated. The hatched portion in the figure shows that it is heat-sealed, and the non-hatched portion shows that it is not heat-sealed. 73t is a boundary line between the heating region and the non-heating region, and this boundary line 73t has the same shape as the outer shape of the non-heating portion 73 of the heat seal roll 71.
Since the absorber 5 is located inside the boundary line 73t,
The absorber 5 is not thermally deteriorated. The hatched portion outside the boundary line 73t is a portion in which the surface material sheet 4S and the back surface material sheet 6S (not shown) are sandwiched by the heating portion 72 of the heat seal roll 71 and heat sealed. 83t is the cutter blade 83 on the die-cut roll 82 of the article cutting section 80 described later.
Is a line to be cut, but details will be described later.

FIG. 12 is a schematic perspective view of the article cutting section 80. As shown in the figure, the article cutting unit 80 includes an anvil roll 81, a die-cut roll 82, and a feed roll 85.
And are arranged so as to face each other in that order. The anvil roll 81, the die-cut roll 82 and the feed roll 85 in the article cutting unit 80 are substantially the same as the anvil roll 31, the die-cut roll 32 in the cutting unit 30 and the feed roll 51 in the polymerization unit 50, respectively. However, on the surface of the die-cut roll 82 of the article cutting unit 80, a cutter blade 83 having a shape slightly larger than the heat-sealing roll 71 of the heat-sealing unit 70,
The die-cut roll 82 is formed on the roll circumferential surface in multiple rows in the roll width direction. Then, as shown in FIG. 2, the front material sheet 4S and the back material sheet 6S with the multi-row absorber 5 sandwiched therebetween are the anvil roll 81 and the die cut roll 8 respectively.
2. The space between the feed rolls 85 is fed in the shape of S in side view. 86 is a suction hole. The roll widths of the anvil roll 81, the die-cut roll 82, and the feed roll 85 may be determined according to the widths of the surface material sheet 4S and the back surface material sheet 6S that are fed.

With the above configuration, the article cutting section 80 can die-cut the sanitary article 1 from the surface material sheet 4S and the back material sheet 6S with the multiple rows of the absorbers 5 sandwiched therebetween, as described below. The surface material sheet 4S and the back surface material sheet 6S with the multi-row absorber 5 sandwiched therebetween are sent between the anvil roll 81 and the die-cut roll 82, and the cutter blades of the anvil roll 81 and the die-cut roll 82.
It is sandwiched by 83 and the sanitary article 1 is die-cut in multiple rows.
The cut multi-row sanitary article 1 is sucked and fed by a negative pressure in a suction region (not shown) as the die-cut roll 82 rotates. It is delivered to the feed roll 85 by negative pressure suction of 85. From here, the feed rolls 85 feed the respective rows of sanitary articles 1. Then, when the feed roll 85 further rotates, the feed roll 85 is fed to a position facing a roller (not shown), and is pressed against a multi-row packaging film sheet 2S described later that is fed by the roller. The sanitary article 1 is packaged by this packaging film sheet 2S, which will be described in detail later.

With the above-described structure, the multi-row manufacturing apparatus 10 for sanitary products operates as follows to manufacture the sanitary products 1. First, the surface material sheet 4S fed from the surface material roll 4R has the water repellent adhesive applying section 20.
The water-repellent adhesive 8 is applied by. The application area of the water-repellent adhesive 8 is the inner peripheral edge portion of the punched shape of the surface material sheet 4S as shown in FIG. On the other hand, the absorber sheet 5S fed from the original roll 5R of the absorber is die-cut by the cutting unit 30. On the other hand, the adhesive 9 is applied by the adhesive applying section 40 to the backside material sheet 6S fed from the backing material roll 6R. Next, the absorbent sheet 5S is fed between the anvil roll 31 and the die-cut roll 32 of the cutting part 30, and here, the absorbent body 5 is formed from the absorbent sheet 5S in multiple rows in the width direction of the absorbent sheet 5S. Be pulled out. As the die-cut roll 32 rotates, the cut multi-row absorbers 5 are sucked and fed under a negative pressure in the region of the rotation angle θ1 and come into contact with the feed roll 51 of the superposition section 50.
The negative pressure on the side disappears, and the negative pressure is sucked by the feed roll 51 to be delivered to the feed roll 51. From here, the absorbent rolls 5 are fed in multiple rows by the feed rolls 51. Since the peripheral speed of the feed rolls 51 is higher than the peripheral speed of the die-cut rolls 32, the absorbent rolls 5 adjacent to each other in the roll circumferential direction are delivered each time. The distance d2 between them is widened. And widened spacing
When the feed roll 51 rotates by the rotation angle θ2 while keeping d2, the absorbers 5 in each row are fed to the position facing the presser table 52, and are pressed against the backing material sheet 6S sent on the presser table 52. .

Finally, the sheet in which the surface material sheet 4S, the absorber 5 and the back surface material sheet 6S are laminated is die-cut in the article cutting step 80P to become the sanitary article 1.

FIG. 4 is a side view of the cutting section 30 and the overlapping section 50, FIG. 5 is an enlarged perspective view of the cutting section 30, and FIG. 6 is a sectional view of the die-cut roll 32. As shown in FIG. 4 and FIG. 5, the cutting unit 30 has an anvil roll 31 and a die-cut roll 32 arranged to face each other, and the absorber sheet 5S is fed between them. Details of the cutting unit 30 will be described later. The overlapping section 50 is the die-cut roll 3 of the cutting section 30.
The feed roll 51 is arranged so as to face 2 and the pressing table 52 is arranged so as to face the feed roll 51. The back surface material sheet 6S is sent to the upper surface of the pressing table 52, and the absorber 5 is sequentially superposed on the back surface material sheet 6S. Reference numeral 40 denotes an adhesive application section, which is composed of a known nozzle and applies the adhesive 9 to the back surface material sheet 6S at equal intervals. In this embodiment,
By making the diameter of the feed roll 51 larger than the diameter of the die-cut roll 32, the peripheral speed thereof is made higher than the peripheral speed of the die-cut roll 32, the reason for which will be described later.

As shown in FIG. 5, the die-cut roll 32
A cutter blade 33 in the form of a sanitary article is formed on the surface of the roll, and the cutter blade 33 is formed in the circumferential direction at intervals d as close as possible. Moreover, the cutter blade 33 is used for the die-cut roll 3
A plurality of rows (two rows in the figure) are mounted side by side on the roll peripheral surface in the width direction of the roll. A large number of suction holes 34 are formed on the roll surface surrounded by the cutter blade 33.

Referring again to FIG. 4, θ1 is the suction area of the die-cut roll 32, and the absorber 5 is the absorber sheet 5S.
It corresponds to the angle of rotation from the cut to the delivery to the feed roll 51. θ2 is a suction region of the feed roll 51, and corresponds to a rotation angle from when the absorber 5 is delivered to the feed roll 51 to when it is pressed against the presser table 52. The mechanism that applies a negative pressure between the suction regions θ1 and θ2 is the first and second suction mechanisms described below, respectively.

The number N of rows of the cutter blades 33 in the die-cut roll 32 is not particularly limited as long as it is not only two rows but also a plurality of rows. However, the larger the number N, the more sanitary articles 1 can be produced within a fixed time. Therefore, it is suitable for mass production. of course,
The width of the absorber sheet 5S may be determined according to the width of the die-cut roll 32. If the number N of rows of the cutter blades 32 in the die-cut roll 32 is large, the width of the absorber 5S is widened to the number N of rows. If the number is small, the width of the absorber sheet 5S may be narrowed. Furthermore, it is preferable to put the sponge 35 in the cutter blade 33 for the following reasons. As shown in FIG. 6, the sponge 35 is put in a portion surrounded by the cutter blade 33,
A suction hole 34 is also formed in this sponge 35. When this sponge 35 is put, there are the following advantages.
Anvil roll 31 and die-cut roll 32 shown in FIG.
When the absorbent sheet 5S is fed in between, the absorbent body 5 is cut from the absorbent body sheet 5S. However, when the absorbent body 5S is cut, even if the absorbent body 5 is fitted into the cutter blade 33, Since the sponge 35 pushes back, the sponge 35 does not get stuck in the cutter blade 33 and cannot be taken out. On the other hand, during suction, negative pressure acts through the suction holes 34 of the sponge 35, so that the suction is securely performed and the inconvenience of dropping during the suction does not occur.

Next, the first and second suction mechanisms will be described. Since the both are substantially the same, the superposition processing section 50 shown in FIGS.
The second suction mechanism applied to the feed roll 51 of No. 1 will be described first. A large number of suction holes 54 are formed on the surface of the feed roll 51, a duct 55 communicating with each suction hole 54 is formed in the feed roll 51, and this duct 55 is opened on one side wall of the feed roll 51. . A fixing plate 56 is attached in close contact with the opening side wall of the duct 55, a duct 57 is formed on the fixing plate 56, and a vacuum pump 58 is connected to the duct 57. The duct 57 is formed to be long in the circumferential direction,
It is formed in an angular range corresponding to the suction area θ2. With this configuration, the feed roll 5 of the polymerization processing unit 50
While rotating 1, No. 1 performs the suction action only within the range of the angle region θ2, and returns to atmospheric pressure outside the angle region θ2, and the negative pressure does not act. The first suction mechanism in the die-cut roll 32 has substantially the same configuration as the second suction mechanism, and is different only in that the suction holes 34 are formed in the region surrounded by the cutter blade 33. . Furthermore, the width of the feed roll 51 of the superposition processing section 50 may be determined according to the width of the die cut roll 32.

With the above structure, the cutting section 30 and the overlapping section 50 operate as follows. FIG. 9 is an explanatory view of the action of the cutting section 30 and the overlapping section 50,
(A) is a plan view of absorber sheet 5S, (B) is a plan view of backing material sheet 6S. As shown in FIGS. 4 and 9, the absorbent sheet 5S is fed between the anvil roll 31 and the die-cut roll 32 of the cutting unit 30,
Here, the absorber 5 is die-cut from the absorber sheet 5S in multiple rows in the width direction of the absorber sheet 5S. At this time,
As shown in FIG. 9 (A), the gap d1 between the absorbers 5 is the same as the gap d between the cutter blades 33 shown in FIG. 5, and the gaps d1 are very small. This is preferable because the material is not wasted. The cut absorber 5 is a die-cut roll 3 as shown in FIG.
With the rotation of 2, the region of the rotation angle θ1 is sucked and sent with a negative pressure, and when it comes into contact with the feed roll 51 of the superposition processing section 50, the negative pressure on the die cut roll 32 side disappears, and the negative pressure of the feed roll 51 is sucked. It is delivered to the feed roll 51. The absorbent body 5 is fed from here by the feed roll 51. Since the peripheral speed of the feed roll 51 is higher than the peripheral speed of the die-cut roll 32, the interval d2 between the adjacent absorbent bodies 5 is widened each time it is delivered. . And
When the feed roll 51 rotates by the rotation angle θ2 while maintaining the widened distance d2, the absorber 5 moves to the pressing table 52.
To the position facing the sheet, and is pressed against the backing material sheet 6S being fed on the holding table 52. The back surface material sheet 6S is coated with the adhesive 9 by the nozzle of the adhesive application section 40 in the previous step. Therefore, each time the absorbers 5 are pressed onto the backing material sheet 6S on the pressing table 52, the absorbers 5 in each row are placed on the backing material sheet 6S via an adhesive as shown in FIG. 9B. The back surface material sheet 6S is bonded in multiple rows in the width direction.

Next, as shown in FIG. 2 again, the front surface material sheet 4S and the back surface material sheet 6S are sent to the press section 60 via the feed belt 59 while sandwiching the multiple rows of absorbers 5. The press portion 60 is provided to prevent positional displacement of a portion that is to be heat-sealed by the heat-sealing portion 70 described later. The pressing unit 60 is composed of a pair of flat rolls, and the front surface material sheet 4S and the back surface material sheet 6S with the multiple rows of absorbers 5 sandwiched therebetween are sandwiched between the pair of flat rolls and pressure bonded. . Then, the front surface material sheet 4S and the back surface material sheet 6S, which are pressure-bonded so that the absorber 5 is not displaced, are sent to the heat seal unit 70 while sandwiching the multiple rows of the absorbers 5.

FIG. 10 is a schematic perspective view of the heat seal roll 71 of the heat seal portion 70. As shown in the figure, the heat seal part 70 is composed of a pair of heat seal rolls 71, and the surface material sheet 4S with the multi-row absorber 5 sandwiched between the heat seal rolls 71, 71. The backing material sheet 6S is sandwiched and heat-sealed. The pair of heat-sealing rolls 71 are arranged in multiple rows in the roll width direction, and sanitary article type non-heating portions 73 are provided at equal intervals in the roll circumferential surface direction. The non-heated portion 73 is a recess formed slightly larger than the absorber 5 so that the absorber 5 is not thermally deteriorated by the heating portion 72 described later. The portion of the pair of heat-sealing rolls 71 except the non-heating portion 73 in the peripheral surface portion is a heating portion 72, which is for melting the surface material sheet 4S and the back surface material sheet 6S to perform heat sealing. Is. The roll width of the heat seal roll 71 is determined by the surface material sheet 4S being sent.
It may be determined according to the width of the back surface material sheet 6S .

With the above-mentioned structure, the pair of heat sealing rolls 71 can heat seal the front material sheet 4S and the back material sheet 6S as follows. When the pair of heat seal rolls 71 of the heat seal unit 70 rotate, the heating unit 72 and the non-heating unit 7 of each heat seal roll 71 are rotated.
3 overlap alternately.

Therefore,
In this case, (N-1) film cutters 101
May be arranged side by side in the width direction of the original sheet 2T.

FIG. 18 is a schematic perspective view of the deviation preventing adhesive applying section 110 and the folding section 130. As shown in FIG. 15 and FIG. 18, the deviation preventing adhesive applying section 110 is provided.
Is composed of a well-known nozzle 111, and the deviation preventing adhesive applying section 110 is a multi-row packaging film sheet 2S.
The adhesive 3 is applied on the packaging film sheets 2S in each row at equal intervals in the longitudinal direction. Therefore, the plurality of nozzles 111 may be installed corresponding to the packaging film sheets 2S in each row. Between the deviation preventing adhesive applying section 110 and the next overlapping section 120 ,
The article cutting unit 80 of the multi-row manufacturing apparatus 10 is located. Therefore, the sanitary article 1 can be placed on the adhesive 3 on the packaging film sheet 2S. The superposing section 120 is composed of a roller 121 arranged so as to face the feed roll 85 of the article cutting section 80 in the multi-row manufacturing apparatus 10, and the sanitary article 1 in which the suction action of the feed roll 85 is released is provided in each row. It is compressed and bonded onto the adhesive 3 on the packaging film sheet 2S. Therefore, the sanitary article 1 manufactured by the multi-row manufacturing apparatus 10 remains in the multi-row manner and the packaging film sheet 2 of each row is overlapped by the overlapping section 120 of the multi-row packaging apparatus 90.
It is superposed and joined to S.

The folding section 130 is provided with a rotatable tri-fold hold roll 131, a sailor 132 and nozzles 135 in multiple rows. The tri-fold hold roll 131 has a roll width smaller than the width of the packaging film sheets 2S in each row, presses the central portion in the traveling direction of the packaging film sheets 2S in each row from above, and fixes the packaging film sheets 2S in each row. It is rotatably provided in a vertical plane at a position where it is bent in a concave shape in a cross-sectional view in the width direction. For this reason, in each of the packaging film sheets 2S in each row, the sanitary article 1 may be placed inside and the packaging film sheet 2S in that row may be molded together with the sanitary article 1 into three folds along the longitudinal direction of the packaging film sheet 2S. it can.

FIG. 19 is a schematic perspective view of the temporary bonding section 140. As shown in the figure, the temporary bonding portion 140 is rotatably provided at positions sandwiching the entire row of packing sheet 2S pair of upper and lower heat sealing roll 141 travels at the multiple rows between the rolls, this In the heat seal roll 141, trapezoidal heating portions 143 extending in the axial direction of the roll are provided on the roll circumferential surface at equal intervals in the circumferential direction. This heating unit 1
Since the heating core 144 for generating heat is built in the heating element 43, the temperature of the heating unit 143 becomes high. By the way, a portion between adjacent sanitary products 1 on each row of the packaging film sheet 2S is a gap portion 7, and the gap portion 7 is cut along a width direction of the packaging film sheet 2S by a cutting portion 170 described later. It is the part that

With this configuration, the temporary adhesive section 140 operates as follows. When the sanitary article 1 folded by the packaging film sheets 2S in each row is located between the pair of heat seal rolls 141, the heating portions 143 of the pair of heat seal rolls 141 are not in contact with each other. Therefore, any row of the sanitary article 1 is not pressed by the heating section 143 or deteriorated by the heat of the heating section 143, and passes between the pair of heat seal rolls 141 and 141. When the gap portion 7 in each row of the packaging film sheets 2S is located between the pair of heat-sealing rolls 141, 141, the heating portion 143 of the pair of heat-sealing rolls 141 causes the gap between the packaging film sheets 2S. The part 7 is sandwiched. Therefore, the heat of the heating portions 143 of the pair of heat-sealing rolls 141 melts the gap portions 7 of the packaging film sheets 2S in the respective rows to press and temporarily bond them. Therefore, the temporary adhesive portion 140 is
Since the gap portions 7 between the adjacent sanitary products 1 on the packaging film sheets 2S in all the rows can be temporarily adhered, the packaging film sheets 2 in all the three folded rows can be provided.
The effect that the position shift of S can be prevented is produced. In addition,
The roll width of each heat seal roll 141 may be determined according to the width of the packaging film sheet 2S sent in and the number N of rows thereof.

FIG. 20 is a schematic perspective exploded view of the film dissolving section 150. As shown in FIG.
0, a pair of upper and lower film dissolving mechanisms is provided at positions sandwiching the temporarily bonded packaging film sheets 2S in all rows, and the film dissolving mechanisms are used to remove the gap portions 7 of the packaging film sheets 2S in each row. It is to dissolve. Although the film dissolving mechanism is shown separately in the drawing for the sake of explanation, the pair of film dissolving mechanisms are provided close to the packaging film sheet 2S. In each of the upper and lower film melting mechanisms, a pair of front and rear rolls 151 are rotatably opposed to each other, and a mesh belt 153 is wound between the pair of front and rear rolls 151 and 151. This mesh belt 1
53 rotates in the traveling direction of the packaging film sheet 2S in synchronization with the packaging film sheet 2S when the roll 151 is rotated. Of course, the packaging film sheets 2S in each row are all running in synchronization.

The mesh belt 153 is made of a heat conductive belt made of stainless steel or the like, and heat insulating materials having heat insulating properties such as silicon rubber and asbestos are alternately laminated in the running direction of the mesh belt 153. The surface to which the heat insulating material is attached is a heat blocking unit 154, and the heat blocking unit 154 blocks heat of a hot plate 155 described later. On the other hand, the heat shield 15 in the mesh belt 153
The surface excluding 4 is the heat transmitting portion 156.
56 transmits the heat of the hot plate 155 described later.
The mesh belt 153 can be adopted without particular limitation as long as it has heat conductivity and heat resistance such as iron as well as stainless steel. Further, as the material for forming the heat shield 154 of the mesh belt 153, not only silicon rubber and asbestos but also those having a heat insulating property such as carbon fiber and glass fiber can be used without particular limitation. Note that the belt width of the mesh belt 153 may be determined according to the width of the sent packaging film sheet 2S and the number N of rows.

A hot plate 155 for generating heat is arranged between the pair of rolls 151, and the heat generated from the hot plate 155 melts the gap portions 7 of the packaging film sheets 2S in each row. . The hot plate 155 has a built-in heater made of metal such as brass, copper, iron or aluminum, and generates heat by electric resistance of the metal when energized, and the magnitude of the electric current can be adjusted. You can adjust the temperature of heat by.

When all the rolls 151 of the film dissolving section 150 are rotated, the mesh belt 153 runs in the same direction and in synchronization with the packaging film sheets 2S in all the rows. Therefore, the heat of the hot plate 155 is transmitted through the heat transmitting portion 156 of the mesh belt 153, and this heat is generated in the gap portion 7 of the packaging film sheet 2S in each row.
Always dissolve. On the other hand, since the heat of the hot plate 155 is blocked by the heat blocking portion 154 of the mesh belt 153, all the sanitary articles 1 folded on the packaging film sheet 2S in that row are not heated and do not deteriorate. That is, the film dissolving section 150 can dissolve only the gap portion 7 between the adjacent sanitary products 1 on the packaging film sheets 2S in each row in all the packaging film sheets 2S without degrading the sanitary products 1. Has the effect.

FIG. 21 is a schematic perspective view of the cooling adhesive section 160. As shown in FIG. 21, in the cooling adhesive section 160, a pair of upper and lower cooling seal embossing rolls 161 are rotatably provided at positions where the packaging film sheet 2S is sandwiched between the rolls.
Numerals 1 and 161 rotate in synchronization with the traveling speed of the packaging film sheets 2S in each row. Of course, the packaging film sheets 2S in each row are all running in synchronization. This cooling seal embossing roll 161 is
Trapezoidal cooling portions 163 extending in the axial direction of the roll are attached to the circumferential surface of the roll at equal intervals in the circumferential direction.
The cooling portion 163 of the cooling seal embossing roll 161
Unlike the heat-sealing roll 141 of the temporary bonding section 140, does not generate heat but is for cooling the gap portions 7 of the packaging film sheets 2S in each row. Each of the cooling seal embossing rolls 161 has a cylindrical shape, and the roll shaft portion is formed in a hollow shape. A hose 164 is connected to both ends of the hollow portion, and cooling water is flown into the hose 164. . With this cooling water, the cooling unit 163 can be constantly cooled. 165
Is a rotary connector for preventing the hose 164 from twisting. The cooling method of the cooling seal embossing roll 161 is not limited to the water cooling as described above.
Although various types of devices may be adopted such as those that are cooled by electricity or a pump, those that are cooled by water are preferable because they are inexpensive. Furthermore, the roll width of the cooling seal embossing roll 161 may be determined according to the width of the packaging film sheet 2S sent in and the number N of rows thereof.

With this structure, the cooling adhesive section 160 operates as follows. As shown in FIG. 21, when the sanitary article 1 on the packaging film sheet 2S in each row is located between the pair of cooling seal embossing rolls 161, 161, the cooling unit of the pair of cooling seal embossing rolls 161. 163 does not touch. Therefore, it is not pressed by the cooling unit 163 and passes between the cooling seal embossing rolls 161 and 161. The gap portion 7 in the packaging film sheet 2S in each row is formed by the both cooling seal embossing rolls 161, 16
When located between the two, the cooling portions 163 of the pair of cooling seal embossing rolls 161 sandwich the gap portions 7 of the packaging film sheets 2S in each row. For this reason,
Cooling part 1 of each cooling seal embossing roll 161
The melted gap portions 7 of the packaging film sheets 2S in each row are cooled and solidified by 63 and 163, and are pressed and bonded by cooling. Therefore, the cooling adhesive portion 160
Cools and solidifies the melted gaps 7 between adjacent sanitary products 1 on the packaging film sheets 2S in all rows, thus preventing the three-fold wrapping film sheets 2S in all rows from opening. At the same time, there is an effect that the sanitary article 1 can be completely packaged and contained in each row of the packaging film sheets 2S.

Although not shown, a pair of upper and lower rotary cutters are rotatably provided in the cutting section 170, and blades are attached to the roll peripheral surface of the rotary cutter. When both rolls of the rotary cutter are rotated and the respective blades are aligned with each other, the gap portions 7 in the packaging film sheets 2S in the respective rows are moved along the width direction of the packaging film sheets 2S in the respective rows.
Is to disconnect. The roll width of the rotary cutter of the cutting unit 70 may be determined according to the width of the packaging film sheet 2S sent in and the number N of rows thereof.

With the above-described structure, the multi-row wrapping device 90 for sanitary products operates as follows, and the sanitary products 1 are packaged with the packaging film sheet 2S.
