Technical field

[0001] The present invention relates to a manufacturing method of disposable wearing articles.

BACKGROUND

[0002] In the case of producing such disposable wearing articles from a web continuing in the flow direction, wherein after cutting the web, while conveying the cut web, other web on the cut © E Bed a method of laminating a is employed (e.g., Patent Document 1).

Incidentally, the point of depositing the individual formed by cutting from the continuous web panel separately sheet is disclosed in Patent Document 2, 3 below.

Patent Document 1: Japanese Patent No. 2, 994, 345 Pat (Figure 3)

Patent Document 2: JP-T-2003-503108 (W_rei_01 / 000122, Abstract)

Patent Document 3: JP-T-2003-503109 (W_rei_01 / 000123, Abstract)

Disclosure of the Invention

[0003] Since the rotational speed of the drum for conveying the web is naturally a limit, in the method of forming the narrow continuous © E Bed cutting web elongated in the flow direction of the cut in the continuous web width, of the continuous web production efficiency since the narrow force (production) is lowered, it may be.

[0004] Therefore, the main object of the present invention is to provide a manufacturing method that can improve the production efficiency of the disposable wearing article.

[0005] manufacturing method of the present invention, taking turn off the element unit in the flow direction from the raw continuous continuous web, there in the manufacturing method of the disposable wearing article disposing the element portion on the sheet Te, comprising a cutting step, a spacing step, the position changing step, and a placement step.

Wherein in the cutting step, the by repeating cutting the tip portion of the continuous web, prior Symbol length of the continuous web in a width direction than the length of the continuous web of the flow direction perpendicular to the flow direction of the continuous web a plurality of element portions are obtained a great shape. The separation as the E, Gunorepu each other comprising a plurality of elements portions are spaced apart from each other in said flow direction. Wherein the posture changing step is generally 90 ° change the posture of the free Murrell each element portions in the group by turning the said group. Wherein in the disposing step, the longitudinal direction of each element portion to which the position is changed in a state along the flow direction of the sheet, each element portion is disposed on the sheet.

[0006] The According to the manufacturing method, by changing the orientation of the elements of the continuous length in the width direction than the length of the web flow direction is larger shape after the continuous web cutting, the element portion is the width direction the length of the flow direction is larger shape than the length of. Therefore, it is possible to cut out against raw length consecutive © E Bed (winding amount of original fabric roll), a lot of element portion than before. For this reason, the number of changeover of the original fabric roll is reduced. In addition, since the wide continuous web is issued wind-, the total amount of the web (total area) is increased to be issued wind-. This good sea urchin, because the total amount of the web is invaluable number of times of the original fabric roll is issued wind-along with the less is to increase large, production efficiency is significantly improved.

[0007] wherein the spacing between each Gunorepu in spaced steps, the next 1 Gunore flop and the group consisting of a plurality of elements portions, i.e. by expanding the interval of flow Direction of another group subsequent to the Gunorepu It may be performed. This spacing is effected to permit the pivoting of at least the group. Thus, the spacing step prior to the posture changing step, or concurrently with the position changing step, performed.

The cutting of a predetermined interval of the continuous web flow direction may be performed by repeating the separating off the tip of the continuous web.

[0008] Incidentally, any of the methods of the present invention also may constitute a core of the absorbent body in which the element portion absorbs hold the fluid in the wearing article. When using the element portion as the core of the absorbent body, since it generally 90 ° changing the position of the core a plurality of co § as a group of portrait in the core of the cutting line force absorber formed between the cores play the role of the groove. Therefore, since the flow fluid along the elongated grooves, the core of the absorber is improved absorption rate of absorbing bodily fluids. The core, as long as it can be absorbing and retaining liquid. The core may have a fluff pulp and / or superabsorbent polymer was Muller pulp.

[0009] In the case of using the element portion as the core of the absorbent body, a sheet-like material to place the element portion may be a sheet material constituting the topsheet or the backsheet such wearing article. Door Ppushito, the body fluids of the wearer, for example, can be transmitted through the urine and blood. Top sheet may have a function of preventing the liquid from flowing backward. The carbonochloridate Kkushito, e.g., polyethylene sheet may be used which does not transmit liquid.

When using the element portion as the core of the absorbent body, the pitch in the sheet Dar-loop consisting of elements part or a plurality of elements section is generally the length along the flow direction of the wearing article produced the same virtuous better Les,. To achieve the arrangement of elements portion or Gunorepu in force Cal pitch, there may be pitch adjustment step of adjusting the pitch of the separate elements portion or Gunorepu and the separation step. Force Cal pitch adjustment step, for example, may be performed after the position change of the element portion or Gunore flop. By the separation step, the element portion or Gunorepu may also be arranged at the same pitch as the predetermined length of the wearing article.

In [0010] the production method, generally parallel to each other the elements of the group, and, while approaching each other les, in the may be disposed on each element portion of the sheet. The present in the manufacturing method may further include a separation step of separating a plurality of element portions included in the group. The separation step, after the cutting step and before the position changing step, or is performed concurrently with said cutting step.

[0011] If the element portion was used as the core of the absorbent body, thus, by separating the plurality of cores, the groove between the cores is formed in a predetermined width, improve the absorption rate to Rutotomoni, the groove because the body fluid is hardly cross increases the leakage preventing effect.

[0012] Another production method of the present invention, cut element portion in the flow direction from the raw continuous continuous web, the element portion A method of manufacturing a disposable wearing article placed over the sheet , a cutting step, a spacing step, the first and second orientation step, in the cutting step and a positioning step, said continuous web is cut at a predetermined interval of the flow direction, the length of the pre-Symbol flow direction a plurality of element portions are large shape length in the width direction of the continuous web perpendicular to the flow direction is obtained than is. Wherein the spacing step, the first element portion of the element portion was made form the cut and the said second element portion next to the first element portion is spaced apart from each other is the direction of flow. In the first position changing step, the posture of the first element portion is changed to approximately 90 ° rotated orientation in the first direction. In the second position changing step, the posture of the second element portion is said first direction is changed to a posture rotated approximately 90 ° in a second direction opposite. In the arrangement step, the longitudinal Direction element portion to which the position is changed in a state along the flow direction of the sheet, said element portion is disposed on the sheet.

[0013] Also in the production method, by changing the orientation of the elements of not large, the length in the width direction than the length of the continuous web flow direction shape after the continuous web cutting, the element portion is pre Symbol Width a shape long in the flow direction is greater than the length of the direction. Therefore, in the same manner as described above, since the total amount of the web which changeover times original fabric roll issued wind-with less increases, the production efficiency is significantly improved.

Spacing of the elements portions in the separation step is carried out in order to enable the pivoting of at least the elements portions. Thus, the spacing step in front of the first and second posture change process, or simultaneously with the first and second position changing step, performed.

[0014] The present production method Niore, Te, said cutting step Niore Te, wherein a shape asymmetric with respect to the center line of each element portion is along the flow direction, and the second in element unit status posture of is the same as the previous SL first element portion approximately 180 ° rotation posture of the posture of, Yo Le, also be the plurality of element portions are obtained.

In this case, the first element portion is pivoted in a first direction, whereas, because the second element portion is pivoted to the direction towards the second, each element portion is the same orientation in the sheet.

Therefore, in the case of using the element portion is not rectangular as the core of the absorbent body also waste is unlikely to occur in a continuous © E drive.

[0015] Note that the "first of the second element portion next to the element portion" means a second element portion to be subsequently generated following the generation of the first element portion.

Incidentally, disposable wearing articles made according to the present invention, for example, paper Omu', paper pants, sanitary napkins, and the like incontinence pads. Further, the disposable wearing article comprises a semi-product in addition to these products.

In Figure 1, raw Wl, W2 is the raw of the continuous web W. When raw Wl, W2 of © E Bed W is relatively thick, the length of the relatively one original fabric W1 or W2 to the sown web W is relatively short. For this reason, the original anti-Wl, W2 of the changeover occurs frequently. When the web W is to increase the cut-out (disconnected) length, even if thin, occur in the original anti-Wl, W2 of the changeover is frequent. [0020] The continuous web W may be an air-laid non-woven fabric.

Airlaid nonwoven, the pulp fibers and short fibers are uniformly divided fiber into the air, along with the depositing fibers on a rotary multi-hole cylinder or mobile screen belt, inter-fiber bonding by spraying a water-soluble adhesive go say the resulting nonwoven fabric. Air-laid non-woven fabric, may be the main component of the pulp fibers.

[0021] air-laid nonwoven fabric may comprise a superabsorbent resin powder. Airlaid nonwoven, because between elements of fibers constituting the nonwoven fabric is adhesively bonded in a pressurized state, at the time of the later-described cut-out (disconnection) and Chikara卩E, high absorbent resin powder Ya fluff pulp, etc. is less likely to fall off. The continuous web W, nonwoven non airlaid nonwoven, Fuinoremu, paper, or may be a tissue or the like.

[0022] The system shown in FIG. 1, the seam unit 1, behind the first original fabric W1 and a second original fabric W2, and Katsuta unit 2 to cut the web W to a predetermined length, cut the element portion C Les and a Ripi' Chitan device 3 to change the attitude, Ru.

[0023] The seam unit 1, for example is to employ a method such circumferential known as disclosed in JP-A-11-268152. Thus, during one working fabric W1 or W2 is being used, it can be replaced over the new raw W2 or W1 of the other, it is possible to supply the web W is O connexion succession thereto. The first original and the web W of the anti-W1 and the web W of the second raw W2, those same shape, structure.

[0024] scion unit 1 receives the web W that has been sown in the first original fabric roll W1. Scion unit 1, when the remaining amount of the first original fabric W1 is reduced, performs the rerouting to be described later, instead of supplying the web W of the first raw W1 Katsuta unit 2, the web W of the second original fabric W2 and supplies to Katsutayuni Tsu door 2. Seam unit 1 to cut the web W of the first raw W1, by the tip portion of the web W of the second original fabric W2 is connected to the end edge that is cut, said the rerouting is carried out.

[0025] Katsuta unit 2 is provided with a Katsutarora 2a and an anvil roller 2b, that these rollers 2a, 2b is rotated, a predetermined Te 沿Tsu a cutting line extending the leading end of the web W in the width direction of the web W Repeat cutting of the length, to generate a plurality of element portions C. As shown in Figure 2A, the short-les, than the length L to be cut along the flow direction MD1 of the web W, the width of the web W (length in the width direction) Ww. That is, in the state immediately after being cut into Katsuta unit 2, element portion C, the length in the width direction CD you perpendicular to the flow direction MD1 than the length in the flow direction MD1 of the web W is in the magnitude les shape . The web W is formed by cutting element portion C is sent to turn device 3.

[0026] As shown in FIG. 1, the turn device 3 is provided with a turn-drum 5, and first and second Konpeya 31, 32. Upstream of the drum 5 is provided with first Konpeya 31, while downstream of the drum 5 are is provided the second Konpeya 32. The first Konpeya 31 carries a plurality of elements section C at narrow intervals (pitches).

[0027] the turn drum 5, for each group comprising a plurality of elements section C, receiving the element portion C on pad. Rotate while a plurality of pads that received the element portion C is raised peripheral velocity in the circumferential direction of the turn drum 5, together with the increase the distance of the pads adjacent to each other, Pas head is radially turn the drum 5 (Pad Ri by to pivot the normal direction) of the surface of the shaft, as shown in FIG. 2B, it executes the turning pitch adjustment of the group consisting of a plurality of elements section C (between the direction of flow away). Thus, the posture of the element portion C of each group is changed to the state (posture) rotated 90 °.

[0028] As the structure for pivoting the element portion C and groups, for example, JP 63-3175 76 No., Kokoku 7-51143 Patent, JP 2003-199790 and Paragraph 0021- 0024 and in FIG. 2 it is possible to employ various structures such as disclosed structure.

Further, as the structure and method of performing repitching (pitch adjustment) of each group and element unit C together we can employ the structure and method disclosed in JP 2002-345889.

[0029] In FIG. 1, between the drum 5 and the second Konpeya 32, sheet S comprising the topsheet and backsheet such wearing article is introduced. The pad by passing the element portion C to the second con base catcher 32, as shown in FIG. 2C, the element portion C are arranged in the sheet material on S. That is, the attitude changed element section C has its longitudinal direction in a state along the flow direction M D2 of the sheet S, is disposed on the sheet S. At this time, generally parallel to each other each main Motobu C in each group, and, in close proximity to each other, each element portion C is disposed on the sheet S.

[0030] In addition, a laminate element portion C is placed on the sheet S is processed into a disposable wearing article through a predetermined machining process.

The pitch λ of each element portion C is disposed, the same as the length along the flow direction of the wearing article produced. In order to enable arrangement of elements section C of the force Cal Pitchie, for example, the spacing of each group with each other on the front Symbol turn drum 5 separately, as the adjustment of the pitch of each group is performed it may be. In this case, the force mow different pitch adjustment, for example, can be performed after the position change of the respective Gunorepu. Without force mow different pitch adjustment, the separation of the flow direction of each group with each other on the turn drum 5, may be the pitch of each group is the same length as the predetermined length of the wearing article .

[0031] Here, because pivots (position change) as one Gunorepu multiple elements section C as described above, the remaining cutting line during cutting between the element portion C, the cutting line is for a leakage-proof to form a groove G.

[0032] Incidentally, the cutting line (groove G) may be a plurality of even one.

Further, as shown in FIG. 2D, each element portion C may be cut along a line extending line or the cutting line G parallel to a direction extending in a direction crossing the cutting line G. Each element station C, a perforation Μ may be not provided along the each direction.

Further, each element portion Cs as 必 short Nag FIG 2Ε that for the same to one another the shape and size of each element portion C in each Gunorepu, Cc, Cs is a different size and shape from one another Ayoi.

[0033] FIG. 3 shows a second embodiment.

In Figure 3A, a plurality of element portions C, C in each group are spaced apart from each other. Therefore, the groove G has a predetermined narrow width Wg (Fig. 3B).

[0034] After being cut by Katsuta unit 2 of Figure 1, by increasing the flow Re velocity component unit C on the first Konpeya 31, element portion C, and C to each other are spaced apart, the force, mow groove G There is formed. Good record, be carried out at the same time as the cutting of separated from the web W of each element part C. Element portion C of the Gunorepu which is between the release, as in the first embodiment described above, as shown in FIG. 3B, FIG. 3C, after the posture of each group pitch is widened between the groups is changed, the pitch λ of the group is placed on the sheet S in the same state as the predetermined length of the worn article to be produced.

[0035] The remaining structure and manufacturing method of the second embodiment is the same as the first embodiment are denoted by the same reference numerals to the same part content or corresponding portions, and the detailed description thereof will be omitted.

[0036] FIG. 4 shows a third embodiment.
