Description

Sanitary products manufacturing facility

The present invention relates to a sanitary product manufacturing facility. In the present invention, the sanitary product is a concept including a panty liner product, a sanitary pad product, and a delivery pad product, and the sanitary article includes a panty liner, a sanitary pad, and a birth pad.

The present inventor provides the sanitary product (A) as shown in Fig. 26, which is easy to take out the sanitary article 1 from the packaging pouch, is hygienic and has a low manufacturing cost. The sanitary product (A) shown in the above figure is composed of a sanitary article (1) and a packaging film (2). As shown in Figs. 25 (A) and 25 (B), the sanitary article 1 itself is not particularly different from a commercially available product. The sanitary article 1 itself has a shape of a book having both ends blunted, (4), an absorber (5), and a backing material (6) are laminated in this order. Further, an adhesive layer 3 partially coated with an adhesive is formed on the back surface thereof. S is a sealing portion of the sanitary article 1 and the edge portion of the sanitary article 1 is sealed by heat. In this sealing portion S, the surface member 4 of the sanitary article 1, the absorber 5, 6 are adhered to each other.

The packaging film 2 is formed by coating a thermoplastic resin film such as a polyethylene film or a vinyl chloride film with silicon and constitutes an outer packaging pouch as described later. The width W2 of the packaging film 2 is wider than the width W1 of the sanitary article 1 and is adhered to the backing 6 of the sanitary article 1 in a superposed state. The width W2 of the packaging film 2 is wider than the width W1 of the sanitary article 1 when the packaging film 2 and the sanitary article 1 are folded in three stages along the longitudinal direction, Only the packaging film 2 is superimposed on the edges at both ends. When the edges of both ends are sealed by heat, the sanitary product (A) constituting the outer packaging pouch of the sanitary article (1) is completed by the packaging film (2).

In using the sanitary article 1, only one edge 2a of the packaging film 2 needs to be pulled out. As a result, the sanitary article 1 can be taken out from the packaging film 2 and immediately used because it is opened along the seam 7 by the heat at the both edges. The present invention relates to an apparatus for manufacturing a sanitary product (A) in the form of a package as described above.

In a conventional manufacturing apparatus, both the production line and the packaging line are one line, and they are connected in series and automation is performed. However, since there is only one line, there is a certain limit in mass production, and in order to produce more, several lines must be installed in parallel. However, the installation of the lines in parallel requires a very large space, so that the introduction thereof is not simple. In addition, since the increase in the number of lines requires a proportional center of the worker, conventionally there has been a problem that the equipment cost and the labor cost are increased.

The sanitary article manufacturing apparatus 10 and the sanitary article packing apparatus 90 are each a multi-row type of at least two or more rows, and a plurality of products can be manufactured simultaneously in one line.

Next, a sanitary made goods manufacturing apparatus 10 will be described in detail based on Figs. 2 to 14. Fig. Fig. 2 is a side view of the sanitary article manufacturing apparatus 10, and Fig. 3 is a block diagram of the sanitary article manufacturing apparatus 10. Fig. In Fig. 2, reference numerals 4R and 4R denote raw rolls of the surface material, all of which are supplied to the press section 60 via the waterproof adhesive pad 20 via the known joint 9a. The joining portion 9a is a device for connecting the tip of the remaining topsheet material 4S to the end of one of the topsheet materials 4S when all the topsheet material 4S has been released. Accordingly, the surface sheet material 4S is always supplied during operation.

The waterproofing adhesive cloth 20 is composed of a plurality of known nozzles. Since the nozzle is applied to the topsheet material 4S with the waterproof adhesive 8 and is disposed in at least two rows along the width direction of the backsheet material 4S, It can be applied in at least two rows along the width direction of the backsheet material 4S. The waterproof adhesive 8 is applied by a nozzle to a portion of the backsheet material 4S to be an edge of the sanitary article 1, the details of which will be described later.

Further, the waterproof adhesive 8 having waterproof property can be used without particular limitation as long as it is an adhesive such as waterproof hot melt adhesive. The waterproof adhesive 20 is adhered to the topsheet material 4S by the nozzle in the figure but the waterproof adhesive 8 is adhered to the topsheet material 4S by the transfer roll .

5R are raw rolls of the absorber, all of which are fed to the cutting portion 30 via known joining portions 9b. 6R are raw rolls of the backing material, all of which are fed to the overlapping portion 50 through the adhesive portion 40 via the known joining portion 9c. The adhesive applying section 40 applies the adhesive 3 to the backsheet material 6S.

2 and 3, in the sanitary article manufacturing apparatus 10 according to the present embodiment, the waterproof adhesive 8 is first applied to the surface sheet material 4S unwound from the surface roll material 4R, A waterproof adhesive applying step 20P is performed. On the other hand, the shape of the absorber 5 from the absorbing sheet material 5S unrolled from the winder roll 5R of the absorbent body or the surface sheet material And the adhesive application step 40P in which the adhesive 3 is applied to the adhesive layers 6S and 6S. Then, in the superposing process 50P, the absorber 5 is superimposed on the adhesive 3 on the backsheet material 6S.

The backsheet material 6S and the topsheet material 4S are conveyed by the conveyance belt 59 with the absorber 5 sandwiched therebetween and then pressed from above and below so as not to be displaced in the pressing step 60P . The backsheet material 6S and the topsheet material 4S around the absorbent body 5 are heat sealed by the heat sealing step 70P and then conveyed by the conveyance belt 79. [ Finally, the sheet on which the topsheet material 4S, the absorbent 5 and the backsheet material 6S are stuck is turned into a sanitary article 1 in the article cutting process 80P.

4 is a side view of the cutting part 30 and the overlapping part 50, FIG. 5 is an enlarged perspective view of the cutting part 30, and FIG. 6 is a sectional view of the die cut trolley 32. FIG. As shown in Figs. 4 and 5, the cutting portion 30 is disposed so as to face the anvil roll 31 and the die cut trolley 32, and the absorbing sheet material 5S is conveyed therebetween. The cutting unit 30 will be described later in detail. The overlapping portion 50 is provided with a feed roll 51 facing the die cut trolley 32 of the cutting portion 30 and a pressing table 52 is disposed facing the feed roll 51 will be. The backsheet material 6S is fed to the upper surface of the pressing table 52 and the absorbers 5 are successively superimposed on the backsheet material 6S. Reference numeral 40 denotes an adhesive applicator which is made up of a nozzle as known in the art, and the backsheet material 6S is coated with the adhesive 9 at regular intervals. In the present embodiment, the diameter of the feed roll 51 is made larger than the diameter of the die cut trolley 32 so that the main speed is made larger than the main speed of the die cut trolley 22, and the reason for this will be described later .

5, a cutter blade 33 having a shape of a sanitary article is formed on the roll surface of the die cut trolley 32. The cutter blade 33 is arranged along the circumferential direction, (d). Furthermore, the cutter blades 33 are attached to the circumferential surface of the die cut trolley 32 in a plurality of rows (in two rows in the drawing) along the width direction of the roll. A plurality of suction holes 34 are formed on the roll surface surrounded by the cutter blade 33.

Referring again to Fig. 4,? 1 is a suction area of the die cut trolley 32, which corresponds to a rotation angle from when the absorber 5 is cut from the absorbing sheet material 5S to the conveying roll 51 . ? 2 is a suction area of the feed roll 51, which corresponds to a rotation angle that causes the absorber 5 to be pushed by the press table 52 after being led to the feed roll 51. Mechanisms for applying a negative pressure between the suction regions (? 1) and (? 2) are the first and second suction mechanisms, respectively.

The number N of cutter blades 33 in the die cut trolley 32 is not particularly limited as long as it is not only two rows but also a plurality of rows. However, the more sanitary articles 1 can be manufactured within a predetermined time Therefore, it is very suitable for mass production. Of course, the width of the absorbing sheet material 5S may be determined according to the width of the die cut trolley 32. If the number of rows N of the cutter blades 33 in the die cut trolley 32 is large, The width of the absorbing sheet member 5S may be widened and the width of the absorbing sheet member 5S may be narrowed when the number of the rows N is small.

It is preferable to insert the sponge 35 into the cutter blade 33 for the following reason.

6, a sponge 35 is inserted in a portion surrounded by the cutter blade 33, and a suction hole 34 is also formed in the sponge 35. As shown in Fig. When the sponge 35 is inserted, the following advantages are obtained. When the absorbent sheet material 5S is conveyed between the anvil roll 31 and the die cut troller 32 shown in Fig. 5, the absorbent sheet 5 is cut from the absorbent sheet material 5S. When the absorbent sheet material 5S is cut Even when the absorber 5 is inserted into the cutter blade 33, the sponge 35 is pushed out, so that the cutter blade 33 can not be inserted and taken out. On the contrary, during suction, a negative pressure is applied through the suction hole 34 of the sponge 35, so that there is no problem such as being sucked securely and falling down on the way.

The first and second suction mechanisms will be described below. However, since the two are substantially the same, the second suction mechanism applied to the transfer roll 51 of the overlapping work 50 shown in Figs. 7 to 8 First, explain. A plurality of suction holes 54 are formed on the surface of the feed roll 51 and a duct 55 communicating with each suction hole 54 is formed in the feed roll 51 to feed the duct 55 And is opened at one side wall of the roll 51. A fixing plate 56 is provided so as to be in close contact with the side wall on the opening side of the duct 55 and a duct 57 is formed in the fixing plate 56. A vacuum pump 58 is connected to the duct 57. The duct 57 is formed in an angular range corresponding to the suction region 2 when the duct 57 is elongated along the circumferential direction.

With this configuration, the feed roll 51 of the overlapping work 50 performs the suction action only within the range of the angular range? 2 while rotating, and returns to the atmospheric pressure other than the angular range? 1, It does not work. The first suction mechanism of the die cut trolley 32 is different from the second suction mechanism in that the suction hole 34 is formed in a region surrounded by the cutter blade 33 Only. Further, the width of the feed roll 51 of the overlapping work 50 may be determined according to the width of the die cut trolley 32.

With the above arrangement, the cutting portion 30 and the overlapping portion 50 operate as follows. 9A is a plan view of the absorbing sheet material 5S and FIG. 9B is a plan view of the backsheet material 6S. FIG. 9A is a plan view of the absorbing sheet material 5S. 4 and 9, the absorbing sheet material 5S is conveyed between the anvil roll 31 of the cutting portion 30 and the die cut trolley 32. Here, the absorbing sheet material 5S The absorbent article 5 is formed in at least two rows along the width direction of the absorbent sheet member 5S. At this time, as shown in Fig. 9A, the interval d1 between the absorbers 5 is the same as the interval d between the cutter blades 33 shown in Fig. 5 and is arranged at very narrow intervals The material of the absorbing sheet material 5S is not wasted, which is preferable. As shown in Fig. 4, the cut absorber 5 sucks and conveys the area of the rotation angle? 1 at a negative pressure in accordance with the rotation of the die cut trolley 32, 51, the negative pressure on the side of the die cut trolley 32 disappears. Therefore, the negative pressure on the die cut trolley 32 side is delivered to the feed roll 51 by suction by the negative pressure of the feed roll 51. The absorbent 5 is fed by the feed roll 51 because the main feed speed of the feed roll 51 is larger than the main speed of the die cut trolley 32, So that the distance d2 between the two is widened. When the feed roll 51 is rotated by the rotation angle? 2 while the enlarged gap d2 is maintained, the absorber 5 is fed to a position facing the press table 52, Is pressed against the backsheet material 6S that has been transferred onto the backsheet material 52. The backsheet material 5S is coated with the adhesive 9 by the nozzles of the adhesive portion 40 in the previous step. Therefore, whenever the absorber 5 is pressed on the backsheet material 6S on the pressing table 52, As shown in Fig. 9 (B), the absorbent 5 of each row is adhered on the backsheet material 6S through an adhesive in at least two rows along the width direction of the backsheet material 6S.

2, the topsheet material 4S and the backsheet material 6S are pressed against the press portion 60 via the conveyance belt 59 with at least two rows of absorbent 5 interposed therebetween, . The press portion 60 is provided to prevent the position of the portion to be heat-sealed in the heat-sealing portion 70, which will be described later, from being displaced. The press section 60 is constituted by a pair of flat rolls and is provided with a topsheet material 4S and a backsheet material 6S sandwiching at least two rows of absorbers 5 between the pair of flat rolls And press it. The topsheet material 4S and the backsheet material 6S pressed so that the absorbent body 5 is not shifted are conveyed to the heat sealing portion 70 with at least two or more absorbers 5 interposed therebetween.

10 is a schematic perspective view of the heat sealing roll 71 of the heat sealing portion 70. FIG. As shown in the drawing, the heat sealing sheet 70 is composed of a pair of heat sealing rolls 71, and at least two rows of the absorbers 5 are placed between the heat sealing rolls 71 The topsheet material 4S and the backsheet material 6S in the fitted state are sandwiched and heat-sealed.

The pair of heat sealing rolls 71 are provided with at least two or more rows along the width direction of the roll, and non-heating portions 73 having the same shape as the sanitary article are provided at regular intervals along the circumferential direction of the rolls . The non-heated portion 73 is a recess formed to be one size larger than the absorber 5, and the absorber 5 is not deteriorated by heat in the heating portion 72 described later. A portion of the circumferential surface portion of the pair of heat sealing rolls 71 excluding the non-heating portion 73 serves as a heating portion 72. The topsheet material 4S and the backsheet material 6S are dissolved For heat sealing.

The roll width of the heat sealing roll 71 may be determined according to the width of the topsheet material 4S or the backsheet material 6S to be fed.

With the above-described configuration, the topsheet material 4S and the backsheet material 6S can be heat-sealed as follows, with both the pair of thermal sealing rolls 71 being provided.

When 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 of the respective heat sealing rolls 71 are alternately overlapped. The peripheral portions of the absorbers 5 in the respective rows in the backsheet material 4S and the backsheet material 6S are melted to form the backsheet material 4S and the backsheet material 6S ) Can be heat-sealed. Since the absorbers 5 of the respective stars are located in the recesses of the non-heating portion 73 when the non-heating portions 73 are overlapped with each other, 72 or is not deteriorated by heat. 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, so that the above operation is repeated. For this reason, heat sealing between the topsheet material 4S and the backsheet material 6S continues.

11 is a plan view of the topsheet material 4S after passing through the thermal sealing roll 71. Fig. Of course, the absorber 5 is arranged in at least two rows along the width direction of the topsheet material 4S, but since each absorber 5 is substantially the same, It only shows with respect to. In the figure, the hatched portion indicates heat sealing, and the non-hatched portion indicates that heat sealing is not performed. The boundary line 73t has the same shape as the outer shape of the unheated portion 73 of the heat sealing roll 71. [ Since the absorber 5 is located inside the boundary line 73t, the absorber 5 is not deteriorated by heat. The hatched portion on the outside of the boundary line 73t is a portion in which the topsheet material 4S and the backsheet material 6S not shown are inserted into the heating portion 72 of the heat sealing roll 71 and heat- 83t shows a cutter blade 83 on the die cut trolley 82 of the article cutting portion 80 to be described later, which will be described in detail later.

12 is a schematic perspective view of the article cutting portion 80. Fig. As shown in the figure, the article cutting portion 80 is an order in which the anvil roll 81, the die cut trolley 82, and the feed roll 85 are arranged facing each other in order. The anvil roll 81, the die cut trolley 82 and the feed roll 85 in the article cutting portion 80 are respectively fixed to the anvil roll 31, the die cut trolley 32 and the conveying roll 51 of the overlapping portion 50, respectively. A cutter blade 83 having a shape larger in size than the heat sealing roll 71 of the heat sealing portion 70 is formed on the surface of the die cutting trolley 82 of the article cutting portion 80, On the circumferential surface of the roll in the width direction of the roll. 2, the topsheet material 4S and the backsheet material 6S in the state where at least two rows of absorbers 5 are sandwiched between the anvil roll 81 and the die cut trolls 82 And the feed roll 85, and is transported in an S-shape when viewed from the side. 86 is an aspiration ball.

The roll width of the anvil roll 81, the die cut trolley 82 and the feed roll 85 may be determined according to the width of the topsheet material 4S or the backsheet material 6S fed.

The sanitary article 1 is cut from the topsheet material 4S and the backsheet material 6S in a state in which at least two rows of absorbers 5 are sandwiched as follows: Can take the form of.

The topsheet material 4S and the backsheet material 6S in a state in which at least two rows of absorbers 5 are sandwiched are transferred between the anvil roll 81 and the die cut trolley 82, And the cutter blade (83) of the die cut trolley (82), the shape of the sanitary article (1) can be formed into at least two rows. At least two rows of cut sanitary articles 1 are sucked and conveyed by the negative pressure and sucked by the negative pressure, as the die cut trolle 82 rotates, and when it touches the feed roll 85, The negative pressure on the side of the trolley 82 disappears, so that the conveying roll 85 can be driven by negative pressure suction of the conveying roll 85. [ The sanitary article 1 of each row is conveyed by the conveying roll 85 from this time. Then, when the feed roll 85 further rotates, it is conveyed to a position facing the roller (not shown) and pressed against at least two rows of the wrapping film sheet 2S conveyed by the rollers . The sanitary article 1 is packaged by the packaging film sheet 2S, the details of which will be described later.

With the above-described configuration, the sanitary article manufacturing apparatus 10 operates as follows to manufacture the sanitary article 1.

First, a waterproofing agent 8 is applied to the topsheet material 4S, which has been unwound from the surface material roll 4R, by means of a waterproofing adhesive agent shroud 20. As shown in Fig. 13, the application region of the waterproof adhesive 8 is an edge portion of the inner periphery where the top sheet material 4S is formed. On the other hand, the absorbing sheet material 5S unwound from the raw material roll 5R of the absorbent article is shaped by the cutting portion 30 to form the absorbent body 5. [ On the other hand, the adhesive agent 9 is applied to the backsheet material 6S unwound from the backing roll 6R of the backing material by means of the adhesive sheet 40.

The absorbing sheet material 5S is then conveyed between the anvil roll 31 and the die cut trolley 32 of the cutting portion 30 from the absorbing sheet material 5S to the absorbing sheet material 5S The shape of the absorbent 5 is diverted into at least two or more rows along the width direction.

At least two rows of the absorbers 5 cut out are sucked and conveyed by the negative pressure in the region of the rotation angle? 1 in accordance with the rotation of the die cut trolley 32, The negative pressure on the side of the die cut trolley 32 disappears and is conveyed to the feed roll 51 by negative pressure suction of the feed roll 51. [ Since the main speed of the feed roll 51 is larger than the main speed of the die cut trolley 32, the absorber 5 is fed to at least two or more rows by the feed roll 51 from this time, The distance d2 between the adjacent absorbers 5 in the circumferential direction is widened. When the feed roll 51 is rotated by the rotation angle? 2 while maintaining the enlarged distance d2, the absorber 5 of each row is transported to a position facing the pressing table 52, Is pressed against the backsheet material 6S that has been transferred onto the backsheet material 52. [ The backsheet material 6S is coated with the adhesive 9 by the nozzles of the adhesive sheet 40 in the previous step. Therefore, whenever the absorber 5 of each row is pushed on the backsheet material 6S on the pressing table 52, the absorber 5 is pressed against the backsheet material 6S through the adhesive 9 by at least two Or more.

The topsheet material 4S and the backsheet material 6S are conveyed to the press section 60 through the conveyance belt 59 in a state where at least two or more rows of the absorbers 5 are fitted, So that the position is not shifted. The topsheet material 4S and the backsheet material 6S are transferred between the pair of heat sealing rolls 71 of the heat sealing portion 70 in a state in which at least two or more heat absorbing bodies 5 are fitted . The peripheral portions of the absorber 5 of at least two or more rows of the backsheet material 4S and the backsheet material 6S are melted when the heating portion 72 of the thermal sealing roll 71 is overlapped, The sheet material 4S and the backsheet material 6S can be heat-sealed.

The topsheet material 4S and the backsheet material 6S are conveyed to the article cutting portion 80 through the conveyance belt 79 in a state in which at least two or more rows of absorbers 5 are sandwiched. The topsheet material 4S and the backsheet material 6S are transferred between the anvil rolls 81 and the die cut trolls 82 and the anvil rolls 81 and The cutter blade 83 of the die cut trolley 82 can be fitted to the shape of the sanitary article 1 with at least two lines. At least two rows of sanitary articles 1 cut are cut by the cut trolls 82 when the suction region is sucked and conveyed by the negative pressure to contact the feed roll 85 as the die cut trolls 82 rotate, The negative pressure on the conveying roll 85 disappears and is conveyed to the conveying roll 85 by negative pressure suction of the conveying roll 85. [ At this point, at least two rows of sanitary articles 1 are transferred to the sanitary ware packing apparatus 90 described later by the transfer roll 85.

As described above, since the sanitary article can be mass-produced at least in two or more rows, it is not necessary to add the line, and the increase of the equipment cost can be suppressed. In addition, since there is no need to increase the number of lines, it is not necessary to increase the number of workers, and the increase in labor cost can be suppressed. Therefore, there is an effect that a sanitary article can be mass-produced even at a low cost.

FIG. 13 is a plan view showing the sanitary article 1 alone, with the left part being a plan view with reference to the center line of (4), the right part being a plan view excluding the surface material 4, (A) taken along the line BB of Fig.

However, there are some commercially available sanitary articles that have a three-dimensional gath formed at the edge portion thereof. The three-dimensional gathers are designed to prevent liquid such as cold or stool, such as menstrual blood, from leaking to the side of the sanitary article.

As shown in Fig. 13 (A), the sanitary article 1 manufactured by the sanitary article manufacturing apparatus 10 according to the present embodiment is coated with the waterproof adhesive 8 having the waterproof property at its edge portion . The waterproof adhesive 8 having waterproof property bonds the topsheet material 4S and the backsheet 6 to prevent the absorbent body 5 from escaping from between the topsheet material 4S and the backsheet material 6S .

13 (B), the waterproof adhesive 8 is applied to the entire surface of the edge portion of the sanitary article 1, and since it has waterproof property, the waterproof adhesive 8 is applied to the sanitary article 1 ) Or leaking up and down. That is, even if there is no three-dimensional gathers at the edge portion of the sanitary article 1, if the waterproof adhesive 8 having waterproof property is applied, it is possible to prevent the liquid agent such as cold or hot water from leaking to the side of the sanitary article 1 It shows the effect that can be done.

Next, another embodiment of the sanitary ware manufacturing apparatus will be described. Fig. 14 is a flowchart of another example of a method of manufacturing the sanitary article 1. As shown in the drawing, in this manufacturing method, there is no waterproof adhesive applying step 20P for applying the waterproof adhesive 8 having waterproof property to the backsheet material 6S. Therefore, since the waterproof adhesive application step 20P is not carried out, the waterproof adhesive pad 20 is not provided. Since the remaining configuration is substantially the same as that of the sanitary article manufacturing apparatus 10, detailed description of its structure is omitted. Also in this case, since the sanitary article can be mass-produced at least in two or more rows, it is not necessary to add the line, so the equipment cost can be suppressed. In addition, since the line is not added, it is unnecessary to increase the number of the workers, which can suppress the increase of the labor cost. Thus, it is possible to manufacture a large amount of sanitary articles at low cost.

Next, the sanitary ware packaging apparatus 90 will be described.

Fig. 15 is a schematic side view of the sanitary article packing apparatus 90, and Fig. 16 is a flowchart of the packing method of the sanitary article 1.

15, the sanitary ware packaging apparatus 90 according to the present embodiment includes a film cutting unit 100, an adhesive stopper for preventing misalignment 110, a superimposing unit 120, a folding unit 130, A bonding portion 140, a film dissolving portion 150, a cooling and adhering portion 160, and a cutting portion 170 are provided. As shown in Fig. 16, a series of far-end sheets 2T unwound from the far-end roll 21R of the packaging film is cut in at least two or more rows along the width direction of the far-end sheet 2T in the film cutting process 100P And is cut into at least two or more rows of packaging film sheets 2S. The packaging film sheet 2S of each row is coated with an adhesive in the adhesive application step 110P for preventing displacement and the sanitary article 1 is superimposed on the adhesive in the overlapping step 120P. Then, the processes of the folding process 130P, the adhesion process 140P, the film dissolving process 150P, the cooling adhering process 160P, and the cutting process 170P are performed in order from the sanitary article manufacturing apparatus 10 The sanitary article (1) transported to at least two rows is packed by the packaging film (2). Referring again to Fig. 15, as the belt conveyors 115 and 116, the packaging film sheet 2S is sandwiched and transported. 9d are joints and have the same function as the joining portions 9a, 9b and 9c. When all the raw material rolls 21R of one of the packaging films are unwound, the other end of the raw material roll 2R The tip is a connecting device.

The packaged-chain sanitary article (1) is a concept that includes various things such as a panty liner and a pad for giving birth to a sanitary pad. The raw material roll 2R of the packaging film is formed by wrapping a packaging film sheet 2S coated with silicone on one side thereof using a thermoplastic resin film such as polyethylene, polyolefin or vinyl chloride.

Next, each of the portions 10 () - 170 of the sanitary article packing apparatus 90 will be described in detail with reference to Figs. 17 to 24. Fig.

17 is an explanatory diagram of the film cutting unit 100, (A) is a side view, and (B) is a plan view. As shown in Figs. 17A and 17B, the film cutting unit 100 is constituted so that the fabric sheet 2T unwound from the fabric roll 2R of the packaging film is folded in the width direction of the fabric sheet 2T, And cut into at least two or more lines to form at least two or more rows of the broken film sheets 21. The film cutting unit 100 is a film cutter 101 that is disposed so that the film cutter 101 faces the tip of the blade in a direction opposite to the advancing direction of the farther sheet 2T. When the fabric sheet 2T unwound from the fabric roll 2R of the packaging film runs, the fabric sheet 2T is cut by the film cutter 101 of the film cutting unit 100 along at least two And is cut into a plurality of rows of packaging film sheets 2S of at least two rows.

The cutting number of the fabric sheet 2T may be the same as the number of the sanitary articles 1 in the sanitary article manufacturing apparatus 10. [ That is, if the sanitary article manufacturing apparatus manufactures the sanitary article in the N rows, the cloth sheet 2T may be cut into N sheets and the N rows of the wrapping film sheets 2S may be formed in the film cutting section 100. Therefore, in this case, (N-1) film cutters 101 may be arranged in parallel in the width direction of the tail sheet 2T.

18 is a schematic perspective view of the adhesive portion for preventing misalignment 110 and the folding portion 130. FIG.

As shown in Figs. 15 and 18, the adhesive part for preventing misalignment 110 is composed of a nozzle 111 as known in the art, and is provided on at least two or more rows of packaging film sheets 2S, And the adhesive 3 is applied at equal intervals along the longitudinal direction of the film sheet 2S. Therefore, a plurality of nozzles 111 may be provided so as to correspond to the packaging film sheet 2S of each row.

The article cutting portion 80 of the sanitary article manufacturing apparatus 10 is located between the displacement preventing adhesive sheet 110 and the overlapping portion 130 to be described later. Therefore, the sanitary article 1 is put on the adhesive 3 on the packaging film sheet 2S. The overlapping portion 120 is composed of a roller 121 disposed opposite to the feed roll 85 of the cutting portion 80 of the sanitary article manufacturing apparatus 10, The sanitary article 1 whose function has been released is compressed and adhered on the adhesive 2 on the packaging film sheet 2S of each row. Therefore, the sanitary article 1 manufactured by the sanitary article manufacturing apparatus 10 is transferred from the overlapping section 120 of the sanitary article packing apparatus 90 to the wrapping film sheet 2S of each row Overlappingly.

The folding section 130 is provided with at least two rows of three-fold folding hold rolls 131, a sailer 132 and a nozzle 135 for folding into three rotatable stages. The three-sided insert hold rolls 131 are formed so that the width of the rolls is smaller than the width of the packaging film sheet 2S in each row and is pressed from above the central portions in the running direction of the packaging film sheet 2S in each row, The packaging film sheet 2S is provided so as to be rotatable in a vertical plane at a position where the packaging film sheet 2S is bent in a concave shape when it is cut in the width direction. Therefore, in the packaging film sheet 2S of each row, the sanitary article 1 is set inward and the packaging film sheet 2S of the row is wound together with the sanitary article 1 in the longitudinal direction of the packaging film sheet 2S It can be folded into three stages. The sailer 132 is a known device and folds the packaging film sheet 2S made in the three-folded form by the three-stage hold roll 131 along the folded form. The nozzle 135 applies adhesive in a linear shape to the edge portion of the side of the packaging film sheet 2S folded in three stages along the running direction along the longitudinal direction. The adhesive is transferred to the sanitary article 1 through the packaging film sheet 2S, thereby preventing the sanitary article 1 from being displaced.

The number of heat of the three-stage folding holding roll 131, the sailer 132 and the nozzle 135 may be the same as the number of heat N in the sanitary ware manufacturing apparatus 10. [

Fig. 19 is a schematic perspective view of the adhesion portion 140. Fig. As shown in the figure, the adhering portion 140 is rotatable in a position where the upper and lower pairs of heat sealing rolls 141 sandwich the entire packaging film sheet 2S running between the rolls in at least two or more rows The heat sealing roll 141 is provided with trapezoidal heating portions 143 extending in the axial direction of the roll at equal intervals along the circumferential direction on the circumferential surface of the roll. Since the heating unit 143 has a built-in heat core 144 for generating heat, the heating unit 143 becomes hot.

By the way, the portion between adjacent sanitary articles 1 on the packaging film sheet 2S of each row is the gap portion 7, and the gap portion 7 is formed by the cut portion 170, which will be described later, And is cut along the width direction.

With the above-described structure, the adhesive bonding portion 140 operates as shown below.

When the sanitary article 1 folded in the packaging film sheet 2S of each row is located between the pair of the heat sealing rolls 141, the heating portion 143 of the pair of heat sealing rolls 141 contacts It is not. Therefore, even if the sanitary article 1 of any row is passed through the pair of heat sealing rolls 141 without being pressed by the heating section 143 or being deteriorated by the heat of the heating section 143 do. When the gap portion 7 in the packaging film sheet 2S of each row is positioned between the pair of the heat sealing rolls 141, the heating portion 143 of the pair of heat sealing rolls 141 The gap portion 7 of the packaging film sheet 2S is sandwiched. Therefore, the heat of each heating portion 143 of the pair of heat sealing rolls 141 melts the gap portion 7 of the packaging film sheet 2S of each row while pressing and bonding.

Therefore, the adhesive chin 140 can adhere the gap portion 7 of the adjacent sanitary article 1 on the packaging film sheet 2S of all rows, and therefore, It is possible to prevent positional deviation of the sheet 2S.

The width of each of the heat sealing rolls 141 may be determined according to the width and the number of rows N of the packaging film sheet 2S to be transported.

20 is a schematic exploded perspective view of the film dissolving unit 150. FIG.

As shown in the figure, the film dissolving unit 150 is provided with a pair of upper and lower film dissolving mechanisms at positions where the packaging film sheets 2S of all the heat adhering therebetween are sandwiched by the film dissolving mechanism And dissolves the gap portion 7 of the packaging film sheet 2S in each row. For convenience of explanation, although the film dissolving mechanism is shown as being spaced apart from each other in the drawing, the pair of film dissolving mechanisms are provided close to the packaging film sheet 2S.

Each of the upper and lower film dissolving mechanisms is juxtaposed so as to be rotatable and rotatable about a pair of front and rear rolls 151, and a mesh belt 152 is wound around the pair of front and rear rolls 151. When the roll 151 is rotated, the mesh belt 153 travels in the running direction of the wrapping film sheet 2S while synchronizing with the wrapping film sheet 2S. Of course, the packaging film sheets 2S in each row are all running in synchronization.

The mesh belt 153 is made of a thermally conductive belt made of stainless steel or the like and alternately adhered to a heat insulating material such as silicone rubber or asbestos in a running direction of the mesh belt 153. The surface to which the heat insulating material is adhered is a heat end 154. The heat end 154 cuts off heat from the high temperature plate 155, which will be described later. On the other hand, the surface of the mesh belt 153 other than the heat-receiving end 154 is a thermal overflow portion 156 that transmits heat from a hot plate 155, which will be described later.

The mesh belt 153 can be adopted without particular limitation, as long as it has thermal conductivity and heat resistance such as iron as well as stainless steel. The material constituting the train end portion 154 of the mesh belt 153 can be adopted without particular limitation, as long as it has heat insulating properties such as carbon fiber and glass fiber as well as silicone rubber and asbestos.

The belt width of the mesh belt 153 may be determined according to the width and the number of rows N of the packaging film sheet 2S fed.

A high temperature plate 155 for generating heat is disposed between the pair of rolls 151. The heat generated from the high temperature plate 155 causes the gap portion 7 of each wrapping film sheet 2S ) Is dissolved. Since the high temperature plate 155 has a built-in metallic heater such as brass, copper, iron or aluminum, and generates electric current by the electric resistance of the metal when the electric current passes through it, Can be adjusted.

When all the rolls 151 of the film dissolving unit 150 are rotated, the mesh belt 153 travels in the same direction as the wrapping film sheet 2S in all rows while running. Therefore, the heat of the hot plate 155 is transmitted through the thermal overflow portion 156 of the mesh belt 153 to always dissolve the gap portion 7 of the packaging film sheet 2S in each row. On the other hand, since the heat of the plate 155 at a high temperature is blocked by the heat-conducting end 154 of the mesh belt 153, the sanitary article 1 folded on the packing film sheet 2S of the heat- There is no deterioration.

That is to say, the film dissolving unit 150 can prevent the sanitary article 1 from being deteriorated at a time when the gap portion between the adjacent sanitary articles 1 on the packaging sheet sheet 2S of each row in the packaging sheet sheet 2S of all rows, (7) can be dissolved.

Fig. 21 is a schematic perspective view of the cooling and adhering portion 160. Fig.

As shown in Fig. 21, the cooling and adhering portion 160 is rotatably provided at a position where the upper and lower pairs of the embossing rolls 161 for cooling stitches sandwich the packaging film sheet 2S between the rolls, The embossing rolls 161 for embossing rollers 161 and the packaging film sheet 2S for each row. Of course, the packaging film sheets 2S in each row are running in synchronization with each other. In the embossing roll 161 for cooling stitching, trapezoidal cooling portions 163 extending in the axial direction of the roll are attached at regular intervals along the circumferential direction on the circumferential surface of the roll. Unlike the thermal sealing roll 141 of the adhesive section 140, the cooling section 163 of the embossing roll 161 for cooling stitching does not generate heat, To cool the gap portion 7. Each of the embossing rolls 161 for cooling stitching is a cylindrical shape, and the shaft portion of the roll is formed in a hollow shape. Hoses 164 are connected to both ends of the hollow portion, and cooling water flows through the hoses 164 . By this cooling water, the cooling part 163 can be always cooled. Reference numeral 165 denotes a rotary connector for preventing the hose 164 from being twisted.

In addition to the cooling method by water cooling as described above, the cooling method of the cooling embossing roll 161 may be a cooling method by electricity or a pump, and various devices may be employed. However, Cooling method by water cooling is most suitable.

The roll width of the embossing roll 161 for cooling and sealing may be determined according to the width and the number of rows N of the packaging film sheet 2S to be fed.

With the above arrangement, the cooling and adhering portion 160 operates as shown below.

21, when the sanitary article 1 on the packaging film sheet 2S of each row is located between the pair of the embossing rollers 161 for cooling stitching, the pair of the embossing rollers for cooling stitching The cooling section 163 of the cooling fan 161 is not in contact. For this reason, it passes between the embossing rolls 161 for cooling stitching without being pressed by the cooling section 163. When the gaps 7 in the packaging film sheet 2S of each row are located between the embossing rolls 161 for both cooling stitching, the cooling portions 163 of the pair of cooling embossing rolls 161 And the gap portion 7 of the wrapping film sheet 2S in the heat space. For this reason, the cooling portions 163 of the embossing rolls 161 for cooling stitches cool and adhere by cooling each of the gaps 7 in which the packaging film sheet 2S is dissolved by solidification while pressing them.

Therefore, the cooling and adhering portion 160 cools and solidifies the dissolved gaps 7 between adjacent sanitary articles 1 on all the wrapping film sheets 2S of all the rows, The sanitary article 1 can be completely packed and sealed with the wrapping film sheet 2S of each row.

In the cut portion 170, a pair of upper and lower rotary cutters, not shown, are rotatably provided, and a blade is attached to the circumferential surface of the roll of the rotary cutter. The rotary cutter is configured such that the gap portion 7 of the wrapping film sheet 2S of each row is wrapped with the wrapping film sheet 2S of the corresponding row along the width direction of the wrapping film sheet 2S It is cutting.

The roll width of the rotary cutter of the cut portion 70 may be determined according to the width and the number of rows N of the packaging film sheet 2S to be fed.

With the above-described configuration, the sanitary article packaging apparatus 90 operates as follows, so that the sanitary article 1 is packed with the packaging film sheet 2S to produce the sanitary article A. Fig. 22 is an explanatory view of the operation of the sanitary article manufacturing apparatus 90 according to the present embodiment.

As shown in the section 100E of FIG. 16 and FIG. 22, in the cutting portion 100P of at least two rows, a series of fabric sheets 2T unwound from the packaging film roll 2R are cut along the width direction thereof And is cut into at least two or more rows to form at least two or more rows of packaging film sheets 2S.

Then, as shown in the section 100E of Fig. 16 and Fig. 22, on the respective silicones of the packaging film sheet 2S running in at least two rows in the adhesive application step 110P, an anti- The adhesive 3 is applied at regular intervals along the longitudinal direction of the packaging film sheet 2S of each row by the nozzles of the application portion 110. [ Next, as shown in the section 120E of Fig. 16 and Fig. 22, in the overlapping process 120P, the adhesive 120 on each of the packaging film sheets 2S running in at least two rows, The sanitary article 1 is superimposed on the sanitary napkin 3. Then, as shown in the section 130E of Fig. 16 and Fig. 22, the sanitary article 1 is folded by the three-fold folding holding roll 131 of the folding section 130 in the folding step 130P The packaging film sheet 2S running in at least two rows inside is folded in three stages along the longitudinal direction of the packaging film sheet 2S together with the sanitary article 1 respectively. Subsequently, the sheets are folded in three stages by a sailer 132 of the folding section 130, and then an adhesive agent is applied to the edges of the sides of the packaging film sheet 2S in each row in the longitudinal direction by nozzles 135, The packaging film sheet 2S running in a row or more is folded according to the folded form.

As shown in the section 140E of Figs. 16 and 22, in the adhering step 140P, the gap portion 7 of the packaging film sheet 2S running in at least two rows is divided into the pair of columns The sheet is sandwiched between the heating portions 143 of the sealing roll 141 and only the gap portions 7 in the packaging film sheet 2S of each row are melted and bonded by the heat of the heating portion 143. The sanitary article 1 does not deteriorate because the sanitary article 1 on the packaging film sheet 2S of the corresponding row is not pressed by the heating section 143 regardless of the column of the packaging sheet 2S. Therefore, even if the packaging film sheet 2S is coated with silicone, it is possible to prevent the packaging film sheet 2S of all the rows folded in the three stages from being displaced.

As shown in the section 150E of Figs. 16 and 22, the heat of the hot plate 155 of the film dissolving unit 150 in the film dissolving step 150P is transmitted to the heat- The gap portion 7 in the packaging film sheet 2S running on at least two rows is dissolved by the heat of the high temperature plate 155. As a result, On the other hand, since the heat of the hot plate 155 of the film dissolving unit 150 is blocked by the heat shielding portion 154 of the mesh belt 153, even if any of the packaging film sheets 2S, The sanitary article 1 on the sheet 2S is not deteriorated by heat. That is to say, even if the packaging film sheet 2S of any row can dissolve only the gap portion 7 between the adjacent sanitary articles 1 on the packaging film sheet 2S of all rows without deteriorating the sanitary article 1 .

Next, as shown in the section 160E of Fig. 16 and Fig. 22, in the cooling adhering step 160P, the gap portion 7 of the packaging film sheet 2S running in at least two rows is divided into a pair And the cooling part 163 of the embossing roll 161 for cooling stitching of the heat-sealed packaging sheet 2S so as to cool and adhere to the packaging film sheet 2S. The sanitary article 1 on the packaging film sheet 2S is not pressed against the cooling section 163 of the embossing roll 161 for cooling stitching even if the packaging film sheet 2S is in any row, It does not.

In other words, even if a packaging film sheet 2S of any row can be cooled and solidified, the detached gap portion 7 between adjacent sanitary articles 1 on the packaging sheet sheet 2S of the corresponding row can be solidified, The sanitary article 1 can be completely packed and sealed with the wrapping film sheet 2S of each row while preventing the three-folded state of the sanitary article 2S from being released.

Finally, as shown in the section 170E of Fig. 16 and Fig. 22, as shown in the cutting step 170P, by the rotary cutter of the cutting portion 170, The gap portion 7 is cut along the width direction of the packaging film sheet 2S and each sanitary article 1 is packed by the packaging film 2 corresponding thereto.

As described above, sanitary articles can be packaged in at least two rows. Therefore, since it is not necessary to add a line as in the sanitary article manufacturing apparatus 10, an increase in the equipment cost can be suppressed. In addition, since there is no need to increase the number of lines, it is also unnecessary to increase the number of working personnel, so that an increase in labor cost can be suppressed. Therefore, it is possible to manufacture the sanitary product (A) by packaging the sanitary article (1) in a large amount at low cost.

23A is a schematic perspective view, and FIG. 23B is a schematic perspective view of a sanitary article A packaged by the sanitary article packing apparatus 90 according to the present embodiment, Fig.

The sanitary article 1 is packed by the packaging film 2 to become the sanitary article A as shown in Figs. 23 (A) and 23 (B). The sanitary article 1 is a pan liner, a sanitary pad and a birth pad, and the sheet 2S to be packaged is made of, for example, a silicone film coated on a polyethylene film and constitutes an outer package of the sanitary article 1 . In order to take out the sanitary article 1, the packaging film 2 is opened along the gap portion 7 at both ends of the heat-sealed portion by simply pulling the one end edge 2a of the packaging film 2, The sanitary article (1) can be used immediately if it is peeled off.

The following describes another embodiment of the sanitary ware packaging apparatus.

24 is a flow chart of another example of the packaging method of the sanitary article 1; In this packaging method, the heat sealing step (140P), the film dissolving step (150P) and the cooling adhering step (160P) shown in Fig. Accordingly, the sanitary ware packaging apparatus according to another exemplary embodiment of the sanitary article may further include an adhering section 140 for performing the adhering step 140P, a film dissolving step 150P and a cold adhering step 160P, 150 and the cooling and adhering portion 160 are not provided, and instead, the heat sealing portion 180 is provided.

The heat sealing step 180P seals the gap portion 7 between the adjacent sanitary articles 1 by heat when the sanitary article 1 is folded at the packaging film sheet 2S. The heat sealing portion corresponding to the heat sealing step 180P is not shown, but a pair of upper and lower heat sealing rolls may be disposed at a position where the wrapping film sheet 2S of each row running between the rolls runs through at least two or more rows And is synchronized with the traveling speed of the packaging film sheet 2S. In the heat sealing roll, trapezoidal heating portions extending in the axial direction of the roll are provided at equal intervals along the circumferential direction on the circumferential surface of the roll. Since the heating section has a built-in heat generating core for generating heat, the heating section becomes a high temperature.
