  The present invention relates to a method and apparatus for folding disposable wearing articles.

  Conventionally, an apparatus and a method for folding a flap of a disposable wearing article such as a diaper have been provided (Patent Documents 1 and 2).

WO 2010/089964 A WO 2011/152346 A

FIG. 6 shows an example of the diaper.
The diaper back portion 21 is provided with an elastic member F that expands and contracts in the waistline direction X. Therefore, as shown in this figure, the flap 3 protruding from the diaper main body 2 in the waistline direction X is inclined with respect to the main body center line 2C of the diaper main body 2.

  In the manufacturing process of the diaper, the diaper main body 2 and the like are adsorbed and stored. Therefore, the contraction amount of the elastic member F is smaller than the free state of FIG. However, even if the diaper main body 2 is adsorbed and stored, it is inevitable that the elastic member F contracts in the waistline direction X. This shrinkage causes problems as described below.

7A shows the diaper in a state where the diaper is unfolded and the contraction due to the elastic member is removed, and FIG. 7B shows the diaper in a state where the front portion is folded during manufacturing.
7B, the edge E1 of the back portion 21 from which the flap 3 extends during the manufacturing shown in FIG. 7B is drawn toward the center side of the diaper body 2 in the waist direction X at the end E2 side of the diaper body 2. The main body 2 is inclined with respect to the main body center line 2C.

In this state, when folded along a fold line CL parallel to the main body center line 2C of the diaper main body 2, the slanted flap 3 is part of the diaper main body 2 as shown in FIG. It will be in the state which protruded outside from the edge part E2.

It is folded so as to overlap. The skin surface 3a of the flap 3 is folded toward the female fastener 5 of the front portion 20 of the diaper main body 2 in FIG. 1A, and the pair of fasteners 4 and 5 are engaged with each other to form a pair of flaps on the diaper main body 2. The diaper 1 is shipped in a state in which 3 is coupled.

Next, an example of the folding device of the present invention will be described.
FIG. 2 shows a part of the cross section of the folding drum 9.

  The folding drum 9 includes a plurality of sets of folding units (folding devices) 10. As is well known, the folding drum 9 includes a fixed portion 15 fixed to a fixed frame, and a rotating portion 16 supported rotatably around the fixed portion 15.

  As shown in FIG. 3, each folding unit 10 includes a main pad 11, a pair of side pads 12, and a folding mechanism 50.

  Each of the folding units 10 including the main pad 11, the side pads 12, and the folding mechanism 50 is attached to the rotating unit 16 in FIG. 2 and rotates around an axis (not shown) together with the rotating unit 16.

  In FIG. 5A, a pair of sub holding surfaces 12 s of the side pads 12 are provided away from the main pad 11 in the waistline direction X. The sub holding surface 12s may hold at least a part of the portion corresponding to the male fastener 4 of the non-skin surface 3b of the flap 3 of FIG. 1C.

  The folding mechanism 50 in FIG. 2 is closed from the open position Po where the side pad 12 is opened adjacent to the waist direction X of the main pad 11 so that the sub holding surface 12s in FIG. 3 faces the main holding surface 11s. By rotating the side pad 12 with respect to the main pad 11 to the closed position Ps, the skin surface 3a of the flap 3 in FIG. 1B is joined to the non-skin surface 2b of the front portion 20 (FIG. 1A). The flap 3 is folded so that it overlaps with (3).

  Hereinafter, the folding mechanism 50 will be described.

  As shown in FIGS. 2 and 3, the folding mechanism 50 of FIG. 3 has the sub holding surface 12s facing the main holding surface 11s, and the sub holding surface 12s is parallel to the main holding surface 11s. The pair of side pads 12 are rotated with respect to the main pad 11 until the position becomes. Each folding mechanism 50 includes an arm 63, a wrist 64, and a drive mechanism 51, respectively.

  Each of the arms 63 in FIG. 3 rotates about an axis L1 extending in the tangential direction of the drum 9 (FIG. 2). Each list 64 rotatably supports the side pad 12 around the axis L2 at the tip of each arm 63. The axis L2 is parallel to the axis L1. The drive mechanism 51 rotates the arm 63 and the wrist 64 in a predetermined rotation direction in order to fold the flap 3.

  2 to 3 includes an arm rotation mechanism 52 and a wrist rotation mechanism 53, respectively. Each drive mechanism 51 has a symmetrical structure. Hereinafter, the one arm rotation mechanism 52 and the wrist rotation mechanism 53 will be described.

  The arm rotation mechanism 52 rotates from the open position Po adjacent to the main pad 11 shown in FIG. 2 to the main pad 11 shown in FIG. The arm 63 is rotated around the axis L1 so that the side pad 12 moves to the closed position Ps on the outer peripheral side.

  On the other hand, the wrist rotating mechanism 53 rotates the side pad 12 around the axis L <b> 2 in the wrist 64 as the arm 63 is rotated by the arm rotating mechanism 52. The rotation of the wrist 64 and the rotation of the arm 63 causes the side pad 12 to rotate and move to the closed position Ps as shown in FIGS. 2 to 3, and the sub holding surface 12s faces the main holding surface 11s. And the flap 3 is folded.

Next, details of the structure of the arm rotation mechanism 52 will be described.
As shown in FIG. 2, a circumferential cam groove 67 is formed on the outer peripheral surface of the fixed portion 15. On the other hand, the rotating portion 16 is provided with a cam follower 68 guided by the cam groove 67 for each arm rotating mechanism 52. The cam follower 68 is attached to a slider 69, and the slider 69 reciprocates in a direction parallel to the axis of the drum 9 along a rail 61 (FIG. 4).

  The arm 63 is supported so as to be rotatable around the axis L1. As shown in FIG. 3, the arm 63 is provided with a fixed pulley P31 around the axis L1, and a rotary pulley P32 is provided on the axis L2. A belt B3 is wound around the fixed pulley P31 and the rotating pulley P32. P33 is a pulley that meshes with the belt B3.

  2 rotates around the main shaft, the pair of sliders 69 are guided along the rails 61 (FIG. 4) in the closing direction R2 as shown in FIGS. Move to. As a result, the link 65 moves in the closing direction R2, and the arm 63 in FIG. 2 rotates around the axis L1 in the closing direction R2 via the ball joint 62 in FIG.

On the other hand, since the pulley P31 in FIG. 3 does not rotate, the belt B3 rotates by the rotation of the arm 63, and the pulley P32 rotates in the closing direction R2. As a result, the side pad 12 rotates in the closing direction R2 together with the wrist 64.

  Therefore, as the arm 63 in FIG. 2 rotates in the closing direction R2, the wrist 64 rotates in the closing direction R2. Thus, as shown in FIGS. 2 to 3, when the arm 63 rotates in the closing direction R2, the side pad 12 rotates about the axis L1 and also rotates about the axis L2. The side pad 12 rotates to a posture in which the sub holding surface 12s is parallel to the main holding surface 11s, and the sub holding surface 12s faces the main holding surface 11s1.

  Thus, the flap 3 of the diaper 1 of FIG. 1B is folded by rotating.

  Note that the operation (opening operation) in which the side pad 12 of FIG. 3 returns from the closed position Ps to the original open position Po as shown in FIG. 2 is opposite to the operation of rotating in the closing direction R2, and detailed description thereof is omitted. .

  In the embodiment, the main pad 11 and the side pad 12 of FIG. 4 receive a diaper at a receiving position upstream from a position where the diaper is folded. The main pad 11 passes the diaper to a downstream conveying device (not shown) at a downstream position from the folding position. The structure of such a drum will be described.

  The main pad 11 of FIG. 5A receives the back portion 21 (FIG. 1) of the main body 2 by the main holding surface 11s. The main pad 11 moves along a predetermined conveyance circle as the drum 9 rotates while holding the main body 2 on the holding surface 11s. A large number of air holes h1 (FIG. 5) for adsorbing and holding the main body 2 in the state of FIG. 1B, for example, with a negative pressure are opened on the main holding surface 11s.

  Note that another main pad (not shown) may be provided, and this another main pad may have another main holding surface for holding a part of the front portion 20 (FIG. 1B).

  Concavities and convexities corresponding to the thickness of the diaper body 2 may be formed on the holding surface 11s of the main pad 11 of FIG.

  The folding apparatus moves the main pad 11 and the other main pad of FIG. 5A from the state where they are opened adjacent to each other in the longitudinal direction Y to the state where the main holding surfaces face each other and are closed. You may have a mechanism which folds the said diaper main body 2 in two by the said crotch part 22 by rotating said another main pad with respect to a pad.

As shown in FIG. 5A, the side pads 12 are disposed on the end YE side in the longitudinal direction Y of the main pad 11, and a pair is disposed with respect to the main pad 11. The side pad 12 receives at least the end portion E2 in the waistline direction X of the flap 3 of FIG. 1B on the sub holding surface 12s. The sub holding surface 12s (FIG. 5A) holds the end portion E2 of the flap 3 by suction. A plurality of air holes h2 shown in FIG. 5A are opened on the sub holding surface 12s (FIG. 5A) for adsorbing and holding the flap 3 with, for example, a negative pressure.
The air holes h1 and h2 are shown only in FIG. 5 and are not shown in other drawings.

The details of the structure of the folding apparatus as described above are disclosed in WO 2011/152346 A1, and the entire description thereof is incorporated here.

Next, features of the structure of the main folding apparatus will be described.
The main pad 11 is fixed to the rotating portion 16 of FIG. 4 via a base 17 and a pole 18.

An adjustment table 13 is disposed on the surface of the base 17. A side pad 12 is attached to the adjustment table 13 via a bearing table 14, an arm 63, a wrist 64 and the like.

As shown in FIGS. 5A and 5B, the base 17 is provided with an adjustment base 13 in a state where the rotational position can be adjusted. That is, the base 17 shown in FIG. 4 is provided with a positioning center 17C made of, for example, a hole, while the adjustment base 13 is provided with a positioned center 13C made of, for example, a pin. The base 17 is provided with a positioning portion 17P made of, for example, a female screw, while the adjustment base 13 shown in FIG. 5A is provided with a positioned portion 13P made of an arc-shaped long hole.

As shown in FIG. 4, a bolt (fixing means) 70 that penetrates the positioned portion 13P is screwed into the female screw. Thus, the bolt 70 and the female screw fix the adjustment base 13 to the base 17 so as to be rotatable along a plane in which the base 17 extends.

The base 17 in FIG. 5A is formed with a through hole 17H for enabling the slider 69 to reciprocate. On the other hand, the adjustment base 13 is formed with a V-shaped notch 13H for enabling the slider 69 to reciprocate. Further, as shown in FIG. 4, the slider 69 is connected to the arm 63 via the ball joint 62. Therefore, the slider 69 can smoothly reciprocate in any state of FIGS. 5A and 5B.

Thus, as shown in FIG. 5A, the main folding apparatus has a first posture in which the axis L2 of the rotation center of the side pad 12 is parallel to the pad center line L extending in the longitudinal direction Y of the main pad 11. As shown in FIG. 5B, the second tilted so as to approach the main pad 11 as the axis L2 of the rotation center of the side pad 12 extends toward the end YE with respect to the pad center line L of the main pad 11. These postures can be selectively set.

Next, a method for folding the diaper flap will be described.
First, with respect to the pad center line L extending in the longitudinal direction Y of the main pad 11 of FIG. 5B, the axis L2 of the rotation center of the side pad 12 approaches the main pad 11 as it extends toward the end YE. It adjusts beforehand so that it may become a posture inclined to. That is, the bolt 70 of FIG. 5A is loosened, the pair of adjustment bases 13 are set to the rotated postures as shown in FIG. 5B, the bolts 70 are tightened, and the postures are adjusted in advance. After the adjustment is performed in advance, the following holding process and folding process are sequentially performed.

In the holding step, the end portion E2 in the longitudinal direction Y of the back portion 21 of the diaper main body 2 in FIG. 1B is contracted in the waist direction X rather than the crotch portion 22 by the tension of the elastic member F. In addition, the back portion 21 is held by the main pad 11 of FIG. 5B in a state where the edge E1 of the front portion 20 is inclined with respect to the virtual main body center line 2C of the diaper main body 2, and the flap 3 (FIG. 1B) is held by the side pad 12.

In the folding step, as described above, the side pad 12 is rotated with respect to the main pad 11 so that the side pad 12 is rotated so that the side pad 12 faces the main pad 11. Accordingly, the flap 3 overlaps the front portion 20 around a virtual fold line CL that is inclined so as to approach the center line 2C as it extends to the end portion E2 of the front portion 20 of FIG. 1B. 3 is folded.

  That is, in the state where the diaper body 2 is folded at the crotch portion 22, the side pad 12 of FIG. 2-3 holding the flap 3 rotates with respect to the main pad 11, so that the flap of FIG. The skin surface of No. 3 is folded over the joint portion 5a (FIG. 1A). At this time, since the sub holding surface 12s and the main holding surface 11s of FIG. 3 are opposed to each other, the double-sided fasteners 4 and 5 are engaged with each other, so that the double-sided fasteners 4 and 5 are reliably engaged. Is called.

  In this way, the diaper main body 2 and the flap 3 of FIG. 1 are folded, and the folded flap 3 is fixed to the diaper main body 2 via the male fastener 4 and the female fastener 5, and the flap 3 is sucked and held. It becomes possible to do.

By the way, the fold line CL in FIG. 1B may be parallel to the inclined edge E1, or may be set to an inclination smaller than the inclination of the edge E1 with respect to the pad center line 2C. For example, when not only the back portion 21 but also the front portion 20 is contracted by the elastic member F, the folding line CL is preferably set parallel to the edge portion E1 as in this embodiment. On the other hand, when the back part 21 contracts and the front part 20 does not contract, the inclination angle of the folding line CL is preferably about half that of the edge part E1.

As an adjustment device for the angle of the adjusting table 13 in FIGS. 5A-5B, a long hole and a pivot pin may be used, or an R guide or the like may be used.

The adjustment angle of the angle of the adjusting table 13 is generally 40 degrees or less, preferably 20 degrees or less, more preferably 10 degrees or less, 0 degrees or more, and most preferably about 3 to 5 degrees. Adjusted in range.

By the way, without providing the adjustment table 13 of FIG. 5B, the axis L2 may be always inclined (fixed) with respect to the center line L. Even in this case, the flap 3 in FIG. 1C can be prevented from protruding from the end E2 of the diaper body 2 to some extent.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, the flap may extend from the edge of the front portion in the direction around the trunk. The diaper may not have the first and second fastener members, and the flap may be temporarily fixed to the main body by a hot melt adhesive.
Each pad does not need to be adsorbed by negative pressure, and the web may be held on the pad by inserting a plurality of needles into the web.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.

  The present invention is applied to a technique for folding a flap of a wearing article such as a disposable diaper.
