The present invention relates to a sanitary product manufacturing facility and a silicone applicator used therein.

In the present specification, the sanitary article refers to an article in which an absorber that absorbs body fluid is sandwiched between a surface material such as a sanitary article, a panty liner, and a back surface material. In addition, a hygienic product is a state in which the product can be marketed by packaging the hygiene product.

By the way, this inventor provides the thing of FIG. 7 as a sanitary product which is easy to take out a panty liner from a packaging stand, is sanitary, and is low in manufacturing cost. The hygiene product A shown in the said figure consists of the hygiene article 1 and the packaging film 2. As shown in FIG. The sanitary article 1 itself is a commercially available sanitary ware and a pantiliner, and the surface material 4, the absorbent body 5, and the backing material 6 are sequentially stacked and the circumference is embossed (7). It is glued in the state. Moreover, the adhesive bond layer 3 which partially apply | coated the adhesive agent is formed in the back surface of the back surface material 6. As shown in FIG.

The packaging film 2 is, for example, coated with silicon on a PE film, and constitutes an outer bag. And the width W2 of the packaging film 2 is used more than the width W1 of the sanitary article 1, and it adhere | attaches on the back surface 6 of the sanitary article 1 in the state superimposed. When the packaging film 2 and the sanitary article 1 are folded in three along the longitudinal direction, the width W2 of the packaging film 2 is wider than the width W1 of the sanitary article 1, so that both ends in the width direction ( Iii) Only the packaging film 2 overlaps the edge. Then, when the both ends of the heat seal (heat seal) (8), the hygiene product A in which the packaging film (2) constitutes the exterior of the hygiene article (1) is produced, using the hygiene article (1) To this end, when the edge 2a of the packaging film 2 is pulled out and the heating sealing part 8 of both ends is peeled off, the sanitary article 1 can be taken out and used immediately. Although the sanitary article of FIG. 7 is what is called a regular type, the flap was formed in both sides of the center part of the sanitary article 1 of FIG. 7, and the adhesive was apply | coated to the flap, respectively. This form is called wing type.

This wing type is used by attaching a flap around the crotch portion of the panties. This wing shape is also folded into three pieces as shown in (b) and (c) of FIG.

The present invention relates to a manufacturing facility for a hygienic product in the form of a package as described above and a silicone applicator used therein.

6 shows a manufacturing line of a conventional hygiene product. 100 is a sanitary ware manufacturer which takes a disc sheet from a disc roll 5R of the absorbent body 5, takes a back sheet sheet from a disc roll 6R of the back plate 6, The surface sheet is blown from the disk roll 4R, and each of the surface material sheets is stacked and cut into three shapes to produce a sanitary article. 110 is a packaging machine, which receives the supply of a band-shaped packaging film from the disc roll 2R of the packaging film 2, puts the sanitary article 1 manufactured by the manufacturing machine 100, and together with the film 2 It is folded into three and heat-sealing back and forth in the line direction to manufacture hygiene product A. By the way, the disc roll (2R) of the packaging film used in the packaging machine 110 is purchased in the film factory specializing in rolls, and is used in the factory installed the production line of the sanitary product manufacturers.

The reason is that the inner surface of the packaging film of the hygiene product must be subjected to peeling treatment. In short, the adhesive 3 shown in FIG. 7 for sticking to underwear at the time of use is applied to the back side of the sanitary article, but since the adhesive 3 and the packaging film 2 cannot be strongly bonded and used, When it is necessary to simply peel off. The treatment according to this necessity is the above peelable treatment, specifically, by applying silicon to the inner surface of the packaging film 2.

Then, the silicone coating must be applied to the film, and then heated by heating a heater or a furnace that passes through the furnace, and further drying by UV processing with ultraviolet rays. However, this drying process generally requires a line length of 15m to 20m, which is considered to be considerably long, and is not practical in terms of cost and equipment except in a dedicated treatment plant.

therefore. Since the packaging film 2 is purchased and used in the state of the silicon-coated disc roll 2R, it contains a considerable amount of silicon coating processing cost in addition to the material cost, and the cost increases, and when the silicon coating is mass-produced, Although the line speed must be made very high, it is practically impossible to match the timing at high speed. Therefore, partial coating cannot be adopted, and front coating is performed. This silicon front coating makes it difficult to seal only by heat sealing in a later step, and requires a cooling step in the middle of the sealing step, and there is a problem that the amount of silicon used is more than necessary.

Also. The wing type of hygiene products has the following problems. In other words, when folds together with the packaging film 2 in three, the adhesive 3 and the packaging film are strongly adhered to each other, and the release paper is used to prevent the adhesive from being peeled off from the packaging film. Process is needed. Therefore, a great deal of processes are required as shown next.

8 shows a manufacturing process of the above wing type sanitary product. (a) shows a part of the strip | belt-shaped packaging film 2, and apply | coats the high temperature melt adhesive 11 here and there like (b), running this strip | belt-shaped film 2. (c) is a process of applying the hot melt adhesive 13 to the release paper 12, and in (d), the release paper 12 is cut and attached to the film 2. In (e), the blade type sanitary ware 1B is placed on the release paper 12. In (f), the adhesive agent 15 is apply | coated next to the part which placed the sanitary article 1B on the packaging film 2, and in (g), the release paper 16 is cut | disconnected on it. In (h), the packaging film 2 and the sanitary article 1B are folded and wrapped together in a single set. Lastly, cutting is performed by heating sealing (see 8) as shown in (i) to complete the sanitary article A.

In the above (c) and (g), the release papers 12 and 16 are placed, and in (b) and (f), the adhesives 13 and 15 must be applied in order to adhere the release papers. The cost rises.

In view of the above, it is an object of the present invention to provide a sanitary product manufacturing facility and a silicone applicator used therein, which can reduce the cost of a packaging film to reduce the manufacturing process of a wing type sanitary article.

The sanitary product manufacturing apparatus of claim 1 partially coats silicone on a necessary portion of the packaging film while unpacking the packaging film from the sanitary article maker for manufacturing the sanitary article and the disc roll wound around the band-like film before applying the silicone. And a silicone applicator for drying and supplying a silicone coated film, and a hygiene article packing machine for packaging a sanitary article manufactured with the hygiene article maker with a film partially coated with silicone supplied from the silicone applicator. The silicone applicator includes a silicone applicator provided in an input part receiving a film from a disc roll, and a drying part provided in an output part for sending a silicone-coated film, wherein the silicone applicator comprises a silicone coating liquid fan and the A pan drum dipped in a pan and a press drum for sandwiching the film against the pan drum, and the pan drum It consists of a doctor (contact) in contact with, the drying unit is disposed in the position to apply hot air to the filter installed on the lower surface of the pass line of the film, UV lamps installed below the filter, and the film passing over the filter It is characterized by consisting of a hot air blower.

Next, embodiment of this invention is described based on drawing.

The sanitary ware making machine 100 is configured as follows. 5R and 5R are disc rolls of an absorber, and an absorber sheet is always sent from one of the rolls to the cutting section 20, cut into, for example, a long or drum shape, and then sent to the polymerization section 21. . (6R, 6R) is a disc roll of the back surface material 6, and a back material sheet is always unrolled from either roll, and is sent to the said polymerization part 21. In the polymerization part 21, the absorber 5 cut | disconnected is placed in a back material sheet. 4R and 4R are disc rolls of the surface material 4, and the surface material sheet is always unrolled from one of the rolls, sent to the press section 22, and superimposed on the upper surface of the absorber 5. It is then heat-sealed in the sealing section 23 and cut at the article cutting section 24. By this, the sanitary article 1 is made.

40 is a silicone applicator which is a feature of the present invention, and details thereof will be described later, but the packaging film sheet 2S partially coated with silicone is guided to the direction change bar 26 and supplied in front of the polymerization portion 25. . Then, the sanitary article 1 is placed on the packaging film sheet 2S, folded in three by the folding portions 30, and heat-sealed at both ends of the heating sealing portion 31, and at the cutting portion 32. The cut is completed to complete the hygiene product A. This sanitary product A is counted with a meter 33 and accumulated in stockka 120.

What is important in the above manufacturing facilities is the silicone applicator 40. Next, the silicone applicator 40 will be described in detail with reference to FIG. 3. In FIG. 3, 35 is a housing, the right side of the figure has an inlet 36 of the uncoated film 2S, and the left side of the figure has an outlet of the coating film 2S ( 37) is provided. In the vicinity of the inlet 36, a stand 38 is provided on which two disk rolls 2r of the uncoated film are mounted, and when the end of one of the rolls 2r passes through, The well-known connector 39 which connects the front end of the roll 2r is provided. The silicon application part 45 is provided in the input part inside the housing 35. The silicone coating part 45 is a press drum for sandwiching the film 2S against the silicone coating liquid pan 41, the plate drum 42 contained in the coating liquid pan 41, and the plate drum 42. (43) and the doctor (44) for dropping out excess silicone liquid brought into contact with the plate drum (42). When the film sheet 2S passes between the plate drum 42 and the press drum 43, the silicon liquid is transferred from the plate drum 42.

The above structure has the same basic structure as a known gravure printing machine, and the plate drum 42 and the press drum 43 are synchronously rotated by a mechanical means such as a gear train, so that the film of the silicone liquid The application position to the sheet 2S does not shift. Even when rotating at high speed, the silicon may be partially coated in the same pattern.

The drying part 50 is provided in the output part of the housing 35. The drying unit 50 passes through the filter 51 provided on the lower surface of the pass line of the film sheet 2S, the UV lamp 52 provided below the filter 51 and the upper surface of the filter 51. It consists of the hot air blower 53 which supplies hot air to 2S. The hot air blower 53 has a blower 54, a blower duct 55, and a discharge duct 56. The filter 51 is made of quartz glass and is preferably broken because of being broken by heat. A drying box 57 is provided on the upper surface. The UV lamp 52 is a known device for UV curing.

In the drying section 50, the film sheet 2S partially coated with silicon is rapidly dried by the UV effect and hot air while passing through the filter 51. Therefore, even if driving at high speed does not cause a drying defect.

As mentioned above, according to the silicone applicator 40 of this invention, even if it uses the uncoated disc roll 2r, it only partially apply | coats to the film sheet 2S unwound from this and apply | coated at high speed. Since drying is possible, there are the following advantages.

That is, since the disk roll 2r can be purchased and used before the silicone coating, the silicon coating processing cost is unnecessary, the cost is low, the timing alignment at high speed is assured, and partial coating is possible. This partial coating of silicon makes it possible to seal only by heat sealing in a later step, which eliminates the need for a cooling step in the middle of the sealing step, resulting in a small amount of silicon used.

Next, the manufacturing process of the sanitary product by the manufacturing equipment of this invention is demonstrated.

4 shows a manufacturing process of a regular hygiene article. Silicone is partially applied to the film sheet 2S of the packaging film 2, and the silicon coating part 2C is formed in the same pattern. This application process consists of the silicone applicator 40. The film sheet 2S on which the silicon coating is completed is turned in the direction of the manufacturing machine line by the direction changing bar 26 in FIG. 1 and supplied to the polymerization portion 25 of the manufacturing apparatus 100. In the manufacturing machine 100, the hot melt adhesive 3 is applied to a part of the upper part of the silicone coating part 2C by the coating tube 27, and the sanitary article 1 cut | disconnected at the article cut part 24 is placed. The sanitary article 1 is temporarily bonded to the film sheet 2S by the adhesive agent 3 in the polymerization portion 25. Then, in the folding part 30 of the packaging machine 110, the sanitary article 1 is folded together with the packaging film sheet 2S in three, heat-sealed in the heating sealing part 31, and the temporary stop tape 9 The heat sealing part 8 is cut | disconnected by the cutting part 32, and the film-packed hygiene product A is completed.

Since the partial coating of the silicon as described above, the amount of silicon used is reduced. In addition, since the sealing process of the heat-sealing part 8 can be performed in the part which does not apply | coat a silicon | silicone, in this case, since it can heat-seal as much as heat is applied, it does not need to apply the complicated process which combines a cooling process with a heat-sealing process. good.

Therefore, according to this invention, cost can be reduced significantly.

5 is an explanatory diagram showing a step of manufacturing a wing type sanitary article.

Silicone is partially applied to the film sheet 2S of the packaging film 2, and the silicone coating portions 2c and 2d are formed in the same pattern. This coating process is performed by the silicone applicator 40. Moreover, while the silicone coating part 2c is a film inner surface side, the silicone coating part 2d is a film surface side, and can apply | coat silicone front and back simultaneously. In this case, it is preferable to open the film 2S after folding one edge of the film 2S in a known folding bar and passing the application part 45 of the silicone applicator 40. Subsequently, the hot melt adhesive 3 is applied to a part of the upper part of the silicone coating part 2c, and the wing-shaped sanitary ware 1B is placed, and is temporarily bonded to the film sheet 2S by the adhesive 3. On the flap 17 of the winged sanitary ware 1B, an adhesive 18 is applied on the manufacturing machine 100 to be temporarily attached to the panty line, or on the pre-coated silicone applicator 2d before folding in three. 18 '). The adhesive 18 'is folded onto the flap 17 of the hygiene article 1B when the film 2S is folded in three, and transferred to the flap 17. Subsequently, the hygiene article 1B is folded together with the packaging film sheet 2 in three, heat-sealed, and the temporary sealing tape 9 is attached to cut the heat-sealing portion 8 to complete the film-packed hygiene product A. do.

In the case of manufacturing this wing type sanitary product, since the partial coating of silicone is carried out as mentioned above, the usage-amount of silicone is small. In addition, since the sealing process of the heat sealing part 8 can be made into the part which does not apply | coat a silicon | silicone, and heat sealing can be carried out as much as heat in this case, the complicated process which combines a cooling process with a heat sealing process is not applied. You don't have to.

Therefore, according to this invention, a considerable cost can be reduced.

In addition, the cost is reduced because it does not need to use the release paper, the manufacturing and packaging process is also simplified, there is an advantage that the cost can be reduced as a whole.

According to the invention of claim 1, the partial coating of silicon on the packaging film reduces the amount of silicon used, thereby reducing the cost by using a non-silicon disc roll, simplifying the heat sealing process, eliminating the use of release paper, and sanitary products. The manufacturing cost of can be reduced.

According to the invention of claim 2, since the silicone coating unit mechanically simultaneously sends the film and the silicone, the partial coating can be accurately performed at high speed.

According to the invention of claim 3, the silicon coated on the film is dried by hot air and UV treatment, thereby enabling high speed drying.
