Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing a disposable absorbent article, and particularly to a method for producing a disposable absorbent article such as a disposable diaper used for infants, adults and the like or for incontinent persons. About.

[Conventional technology]

In conventional disposable diapers, for example,
As disclosed in Japanese Patent No. -40267, a liquid-permeable top sheet and a liquid-impermeable back sheet, and a diaper main body composed of an absorber positioned between these two sheets,
In the diaper main body, a so-called flat type in which a pair of left and right side flaps are integrally formed, arranged on both side edges on the back side of the side flaps, and a fastening tool is fastened on the abdomen side. Are known.

Recently, as disclosed in JP-A-57-77304, the abdominal region and the dorsal region of a pair of left and right side flaps are joined and fixed to each other to form a pair of left and right leg openings and a waist opening. Have been proposed, so-called pants-type disposable diapers have been proposed. The pants-type disposable diaper is configured such that a leg opening and a waist opening are formed to be extendable and contractable, respectively, to fit a body shape. Such pants-type disposable diapers can usually be worn by the wearer in a standing position, and are used for toilet training to promote the infant's "diaper separation", or for incontinent persons or walking. It is considered useful for possible adults.

In addition, Japanese Utility Model Application Laid-Open No. 58-143809 and Japanese Patent Application Laid-Open No. 61-207605 disclose flat-type and pants-type disposable diapers having a good-looking sewing-tailoring appearance, intended to produce disposable garments. A configuration in which a back sheet is covered with a nonwoven fiber is disclosed.

On the other hand, some proposals have also been made on a method of manufacturing disposable diapers. They are basically disclosed in
This method is typified by a cross-flow method in which the longitudinal direction of the absorber is perpendicular to the flow direction as disclosed in JP-A-77304 and JP-A-1-292102.

Generally, these types of disposable diapers have the problem that the productivity is significantly reduced and the cost must be increased. That is, a technique for inserting an elongated elastic member in a direction perpendicular to the flow direction of the continuous web has not been established yet, and a decrease in productivity is caused by this.

Among them, a pants-type disposable diaper with a belt that does not require a side seal and its manufacturing method

And it is cut along the virtual line 34 by the cutting device 33,
Individual absorbent bodies 3 are manufactured. The cut absorbent body 3 is rotated about 90 ° by the reversing device 31 and then sent intermittently to the polymerization roll 34.

On the other hand, the outermost layer sheet band 42 is unwound from a raw material (not shown) and sent to a polymerization roll 34 where the absorbent main body 3 and the outermost layer sheet band 42 are applied to the article main body. The disposable diaper web 49 is formed by being integrally joined through the agent.

A leg hole 49 is formed in the integrated disposable diaper web 49 by a rotary die cutter 45 and cut into individual disposable diapers 21 by a final cutter unit 52. Then, in the next step, tape fastener 23
Is attached to the side flap 22.

Next, a third embodiment will be described with reference to FIG. In the third embodiment, an example of a cross-flow method in which the absorbent main body 3 flows in the longitudinal direction perpendicular to the flow direction is shown.

In the third embodiment, on the outermost layer sheet 2 on which the absorbent main body 3 is intermittently arranged, a top sheet 55 unwound from the raw sheet is further integrated by a polymerization roll group 56. Are joined. Other manufacturing steps are substantially the same as those of the second embodiment. According to the disposable diaper 58 obtained by the third embodiment, the absorbent sheet 3 can be more securely fixed by the topsheet 55.

The individual absorbent main bodies 3 separated in the cutting step 33 are supported by the head of the intermittent transfer device 57, and are flat without being affected by the contraction stress of the elastic member 19 disposed in advance on the absorbent main body 3. While maintaining the shape, the polymerization roll 34
Sent to. It is preferable to include a step of folding the end flap 16a on the upper surface of the absorber in the intermittent transfer step.

In the disposable diapers 1, 21, and 51 obtained by the methods according to the first, second, and third embodiments described above, the back sheet 16 is disposed only in the portion where the absorbent body 17 is placed, so that the flap is used. Is highly flexible and highly breathable.

The use of such a manufacturing method has an advantage that a nonwoven fabric having a sufficient strength can be supplied with respect to a tensile stress applied when a diaper is fixed to a wearer using a tape fastener. As a material used for such a disposable absorbent article, for example, a nonwoven fabric or the like is thin in view of cost. At that time, the strength of the non-woven fabric wrapped around the raw material in the long direction is 5-6 times smaller than the strength in the short direction.
Times better. In the present manufacturing method, it is possible to arrange the long direction in the direction in which the stress of the tape fastener is applied, and a very rational product design can be performed.

As described above, according to the manufacturing method according to the above-described embodiment, the elastic members can be easily arranged, and the absorbent article of the present invention can be manufactured without impairing high-speed productivity.

It goes without saying that the embodiments of the absorbent article according to the present invention and the method of the present invention can be arbitrarily changed and implemented without departing from the gist of the present invention.

For example, a configuration in which a tearing guide means is disposed adjacent to a side seal portion of the disposable diaper 1 of a complete pants type so that the tearing guide means can be easily peeled off from a wearer. The tear guide means may be a slit guide line, a seal portion, or a material which can be easily torn, while having a strength not torn or worn during wearing. .

Further, according to another embodiment of the method of the present invention, the absorbent main body 3 flows perpendicular to the longitudinal direction of the main body, and the first elastic body for the waist is inserted. Each diaper web is made to flow vertically by rotating each body 3 by 90 °. At this time, the second elastic body for the leg is inserted.

〔The invention's effect〕

Advantageous Effects of Invention According to the present invention, it is possible to provide a method for manufacturing a disposable absorbent article that is inexpensive, has excellent flap texture, and has excellent air permeability.

Another advantage of the method of the present invention is that when an inverting device is used to transfer the absorbent main body to the outermost layer sheet, if the elastic member is stretched in the flow direction of the main body of the article, the main body of the article is inverted by 90 °. When transferred to the outermost layer sheet, the elastic member extending in the direction perpendicular to the flow direction is disposed. Therefore, by inverting the elastic member integrally with the article main body, the inversion arrangement is facilitated.

That is, the arrangement of the elastic member in the direction perpendicular to the flow direction has conventionally often reduced the high-speed productivity of the absorbent article. However, it is technically difficult to handle a single thread-like or band-like elastic member. It was due to something.
