Description

  The present invention relates to a packaging body forming apparatus for absorbent articles such as disposable diapers and incontinence pads. More specifically, the absorbent article stack is pressed and clamped by a pair of plates from both sides, and the plates are pressed. An absorbent article that can be rotated to a predetermined angle and stacked in any number of stacks and stored in a packaging bag to form a package. The present invention relates to a packaging body forming apparatus.

  Absorbent articles such as disposable diapers are usually interposed between a liquid-permeable surface sheet disposed at least on the surface side, a liquid-impermeable back sheet disposed on the back surface side, and both of these sheets. An article body is constituted by the absorbent body, and excreta is absorbed and held by the absorbent body via the surface sheet.

  Such an absorbent article is displayed as a package in which a plurality of absorbent articles are stored in a packaging bag. At this time, from the viewpoint of reducing the occupied space at the time of display or for the convenience of handling, for example, as shown in Patent Document 1, each absorbent article constituting the package is an article main body in the folding process of the absorbent article. In general, the sheet is folded in the longitudinal direction smaller than three folds to be compact.

  The absorbent article folded in such a small size is fed into a package forming apparatus to form a package of absorbent articles. Specifically, first, the absorbent article is continuously fed into the integrated body forming means of the packaging body forming apparatus one by one in a direction in which the bent portion is forward in the direction of travel of the conveyor. A predetermined number of absorbent articles are stacked to form an aggregate of absorbent articles. Various devices such as a stacker and an accumulator can be used as the integrated body forming means. The aggregate formed by the aggregate forming means is fed to the aggregate stage number forming means, and is stacked in a plurality of stages (for example, two stages of the upper stage and the lower stage) in the vertical direction, and is then stored in the compact compression storage means. It is fed, stored in a packaging bag, and packaged to form a package.

  However, such a package forming apparatus simply forms an aggregate of absorbent articles by the aggregate forming means, and then stacks the aggregates two by two in the aggregate stage forming means and packages them in two stages. However, it did not have a function of changing the direction of the aggregate formed by the aggregate formation means.

  For this reason, in a conventional absorbent article packaging body forming apparatus, a packaging body having a packaging form in which the orientation of the upper and lower stacks is different (specifically, the folded portions of the upper and lower absorbent articles are opposed to each other). When it is going to form the formed package body or the package body formed by facing the non-bent portions of the upper and lower absorbent articles), it is necessary to rotate the direction of the assembly every other 180 degrees. For this reason, it is necessary to manually change the direction of the integrated body by interposing an operator in a conveyor connecting the integrated body forming means and the integrated body compressing and storing means.

  However, such manual work has a drawback that not only the labor is forced on the worker but also the manufacturing cost is increased due to the labor cost.

Therefore, instead of manually changing the direction of the aggregate, as shown in FIG. 12, an aggregate is formed by the aggregate forming means 210, and this aggregate is sent from the aggregate forming means 210 by the aggregate sending means 220. Then, an absorbent article packaging body forming apparatus 200 in which an integrated body rotating means 230 comprising a reversing device such as a turntable 231 is installed and the direction of the integrated body can be changed by rotating the integrated body by 180 °. Has been proposed. However, when such an integrated body rotating means 230 is provided, the packaging body forming apparatus 200 becomes large, and there is a problem that the equipment space increases.

In this state, each diaper 100 is transferred to the diaper stacking portion 25 by the endless belt 22 that circulates, and a predetermined number of diapers 100 are vertically stacked on the stacking portion 25 (hereinafter referred to as “stacked body”). 11) is formed. The movement operation of the partition plate 21 and the traveling operation of the endless belt 22 in the stacking unit 25 are controlled by a known control device. Further, in this embodiment, each diaper 100 is sent to the stack forming means 20 with the bent part facing forward, but the front and rear body parts 100F, 100B (non-bent part) of the diaper 100 are forward. It may be sent upright in the direction.

  Each diaper 100 supplied to the integrated body forming means 20 includes a liquid-permeable topsheet 101 disposed on the front side as shown in a partially broken development top view of a tape-type paper diaper in FIG. The diaper main body 104 is configured to include at least the liquid-impermeable back sheet 102 to be disposed and the absorbent body 103 interposed between the two sheets 101 and 102, and the buttocks contact portion of the diaper main body 104. Specifically, a stool pocket 105 for storing and holding excrement is provided at a portion of the absorbent body 103 where the wearer's defecation opening is located. The plane shape of the stool pocket 105 is not limited to the shape of the heel widened toward the back side as shown in the figure, and may be various known shapes such as a substantially home base shape and a rectangular shape.

  As a constituent material of the top sheet 101, a material having liquid permeability and hydrophilicity such as a non-porous or perforated nonwoven fabric or a porous plastic sheet is preferably used. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as olefins such as polyethylene and polypropylene, polyesters, and amides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. Also, a core-sheath fiber, a side-by-side fiber, a split fiber, or the like having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can be used effectively. As for the processing method, a nonwoven fabric obtained by an appropriate processing method such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of richness in flexibility and drape, and the thermal bond method is excellent in terms of being bulky and soft, but the surface sheet 101 in the present diaper 100 is not necessarily made of these materials. It is not limited to the processing method.

  In addition, although the surface sheet 101 in this diaper 100 is comprised only by the top sheet, you may be comprised by two layers, a top sheet and a second sheet.

  As the constituent material of the back sheet 102, a liquid-impermeable material made of a plastic sheet such as polyethylene or polypropylene, a nonwoven fabric, or the like, or a material equivalent thereto is preferably used. Other examples include meltblown or film materials made of polypropylene or polyolefin copolymers. Examples of the copolymer include ethylene vinyl acetate, ethylene methyl acetate, ethylene ethyl acrylate, polyvinyl chloride, and the like. A single spunbonded layer made of each of these materials, two layers made of spunbonded and meltblown materials, and the like. By using such a spunbonded material, the back sheet 102 can be given a cloth-like feeling. In addition to the material having such liquid impermeability, a sheet material having air permeability and moisture permeability is applied to the material of the back sheet 102 from the viewpoint of preventing stuffiness. As such a sheet material, a microporous sheet obtained by forming a sheet by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene and then stretching in a uniaxial or biaxial direction is preferable. Used for.

  The absorbent body 103 may be anything that can absorb and retain excreta (particularly body fluids such as urine and water contained in loose stool). Usually, the absorbent polymer powder is mixed in fluffy pulp. It is preferably used from the viewpoint of absorption function and price. Examples of such pulp include cellulose fibers such as chemical pulp and molten pulp obtained from wood, and artificial cellulose fibers such as rayon and acetate. It is preferably used from the viewpoint of price. Therefore, the absorber 103 is thicker than the top sheet 101 and the back sheet 102. The absorbent body 103 is excellent in shape retention, and quickly disperses excrement (particularly bodily fluids such as urine and water contained in the stool) and prevents the excrement once absorbed from returning. It is preferably covered with a water-absorbing paper 103C such as tissue paper or crepe paper, but may be omitted depending on the purpose and needs of the diaper 100 itself.

  The diaper 100 has opposite side edges 106 extending in the longitudinal direction of the diaper main body 104 facing each other and both end edges extending in the width direction of the diaper main body 104 facing each other (hereinafter also referred to as “waist around”). 107F, 107B, and further, in the longitudinal direction of the diaper main body 104, there is a front body 100F, a back body 100B, and a leg periphery 100L located between the front and back bodies 100F, 100B. ing. In addition, elastic elastic members 108l for the legs are provided on the left and right sides of the leg circumference 100L, that is, both side edges 106, 106 of the diaper main body 104, and for the waist around the edge 100B of the back body 100B. The elastic elastic member 108w is attached to the top sheet 101 and / or the back sheet 102 in an extended state. Furthermore, various known fastening tapes 110 are attached to the ends of the left and right side edges 109 of the back body 100B, and various known frontal tapes 111 are attached to the back sheet 102 of the front body 100F. The diaper 100 is worn when the fastening tape 110 is engaged with the frontal tape 111.

  In the present diaper 100, both end portions of the absorbent body 103 are positioned inside the waist circumference portions 107F and 107B of the front and back bodies 100F and 100B, and both side portions of the absorbent body 103 are inside the left and right side portions 106 and 106 of the leg circumference portion 100L. Is located. That is, since the absorber 103 is not disposed on both side portions 106 and 106 of the leg periphery portion 100L and the waist periphery portions 107F and 107B, the thicknesses of the both side portions 106 and 106 and the waist periphery portions 107F and 107B of the leg periphery portion 100L. Is smaller than the thickness of other parts.

  When the book diaper 100 is supplied to the package forming apparatus 10, the diaper 100 is folded in half in the longitudinal direction of the diaper main body 104 as shown in a sectional view in the longitudinal direction of the diaper 100 in FIG. That is, it is preferable that the front body 100F and the back body 100B of the diaper main body 104 are folded so as to face each other. Thereby, even if a so-called fold is formed in the bent portion 112 or the like, the fold is not applied to the stool pocket 105, so that no fold is generated in the stool pocket 105. As a result, since the stool pocket 105 is not deformed, excrement stored in the stool pocket 105 does not leak in the outer peripheral direction. As shown in the figure, the diaper 100 is provided with a waterproof film 113 between the back sheet 102 and the absorber 103, but the waterproof film 113 is omitted depending on the use and needs of the diaper itself. You can also.

  The integrated body 11 formed by the integrated body forming means 20 is forcibly sent out of the integrated body forming means 20 by the integrated body sending means 30.

  The integrated body delivery means 30 is not particularly limited, and various known means such as a pusher can be used. However, the integrated body delivery means 30 can be used in the closed loop formed by the endless belt 22 of the integrated body forming means 20. Arrangement is preferable because the equipment space can be further reduced.

  The stack 11 sent from the stack forming means 20 by the stack sending means 30 is transferred to the stack rotating means 40 according to the conveyor 12 and sent in.

  As shown in an enlarged perspective view in FIG. 4, the integrated body rotating means 40 includes a pair of plates 41 and 41 that hold the integrated body 11 while pressing the integrated body 11 from both sides 11 s and 11 s. It is supported so as to be rotatable around an axis N in the pressing direction. The plate 41 in the packaging body forming apparatus 10 is supported so as to be rotatable around the axis N in the pressing direction clockwise (in the direction of arrow B in the figure), but is supported so as to be able to rotate counterclockwise. May be.

  As shown in FIG. 5, the packaging body 80 formed by the packaging body forming apparatus 10 is rotated by the stacking body rotating means 40 and the stacking body 11 that is not rotated by the stacking body rotating means 40 and has not changed its orientation. The stacked body 11 ′ whose direction has been changed is vertically overlapped, that is, has two stages of an upper stage 81 constituted by the accumulated body 11 ′ and a lower stage 82 constituted by the accumulated body 11. It is a stacked form.

  Such a package 80 is formed by rotating every other stack 11 fed to the stack rotating means 40 by 180 ° clockwise around the axis N in the pressing direction by the plate 41. Can do. That is, the stack rotating means 40 rotates the stack 11 by 180 ° by the plate 41 to form the stack 11 ′ and sends it to the stack stage number forming means 50 as the next means, and then sends it to the stack rotating means 40. The integrated body 11 that has entered is allowed to pass through the plate 41 without being rotated, and is sent out to the integrated body number forming means 50 as it is.

  In addition, when the accumulation body 11 is rotated by the accumulation body rotating means 40, the accumulation body 11 is pressed from both sides 11s and 11s by the plate 41. At this time, it is preferable that the pressing rate is 20 to 30%. When the pressing rate is less than 20%, the pressing force is too weak and the accumulated body 11 collapses during the rotation. On the other hand, when the pressing rate exceeds 30%, the pressing force is too strong and the diaper 100 is provided. The stool pocket 105 may be deformed.

  The stacked bodies 11, 11 ′ that have passed through the stacked body rotating means 40 are transferred to the stacked body stage number forming means 50 according to the conveyor 12 and sent in. The stacked body stage number forming means 50 in the packaging body forming apparatus 10 is set to take out the stacked bodies 11 and 11 ′ that have been fed in and stack them in two stages. That is, it is set to take out the accumulated body 11 ′ and the accumulated body 11 that are sent in one by one and stack them in two stages.

  The stacked body 11 and the stacked body 11 ′ which have been stacked in two stages through the stacked body number forming means 50 are transferred to the integrated body compressing and storing means 60, which is the next means, according to the conveyor 12. In the integrated body compressing and storing means 60, first, the integrated bodies 11 and 11 'stacked in two stages are simultaneously compressed from both sides by applying a certain pressure F by various known compressing means to obtain a width and a bulk. Make it smaller. Note that the pressure F can be appropriately changed depending on the degree to which the aggregates 11, 11 'are compressed. Next, using a variety of known storage means, the stacked bodies 11 and 11 ′ stacked in two stages are stored in the packaging bag 83 while being compressed by the compression means. Finally, the sealing means 70 seals and seals the bottom 84 of the packaging bag 83 using a known sealing means such as heat sealing, whereby the upper stage 81 and the lower stage 82 of the diaper as shown in FIG. A package 80 having a step is formed.

  Moreover, the packaging body 80 formed by the packaging body forming apparatus 10 is formed in a packaging form in which the front and back body parts 100F and 100B of each diaper 100 are opposed to each other as shown in FIG. That is, in the package 80, each diaper 100 of the integrated body 11 ′ constituting the upper stage 81 has the bent portion 112 as the upper side, and each diaper 100 of the integrated body 11 constituting the lower stage 82 has the bent portion 112 as the lower side. It is formed into a packaging form. As a result, when the bottom portion 84 of the packaging bag 83 is sealed, the upper portion 81 of the integrated body 11 ′ is not easily crushed, so that the deformation of the feces pocket 105 provided in the diaper 100 can be further prevented. It can prevent that the lower part of each diaper 100 of the accumulation body 11 which comprises 82 is sealed with the packaging bag 83 (it pinched | interposed into the packaging bag 83).

  As a constituent material of the packaging bag 83, for example, various known flexible sheet materials having flexibility such as a gas-impermeable and liquid-impervious plastic film and a gas-permeable and impermeable fiber nonwoven fabric can be used. As the plastic film, it is preferable to use a film formed from a polyolefin-based thermoplastic synthetic resin such as polypropylene or polyethylene. Moreover, as a fiber nonwoven fabric, what was manufactured by each manufacturing methods, such as a spunlace, a needle punch, a melt blown, a thermal bond, a spun bond, a chemical bond, an air through, can be used. As the constituent fibers of the nonwoven fabric, polyolefin-based, polyester-based, polyamide-based or the like fibers, core-sheath type composite fibers or parallel type composite fibers made of polyethylene / polypropylene, or polyethylene / polyester can be used.

  In addition, although the handle 86 formed of the same constituent material as the packaging bag 83 is normally attached to the top surface 85 of the packaging bag 83, this handle 86 does not need to be attached.

  Further, according to the package forming apparatus 10, the upper stage 81 is configured by the stacked body 11 that has not been rotated by the stacked body rotating means 40, and the lower stage 82 is configured by the stacked body 11 ′ that has been rotated by the stacked body rotating means 40. By doing so, a package 80A having a packaging form as shown in FIG. 6 can also be formed.

  As shown in the drawing, the package 80A is formed in a packaging form in which the bent portions 112 of the respective diapers 100 face each other. That is, each diaper 100 of the integrated body 11 constituting the upper stage 81 has the front and rear body parts 100F and 100B as the upper side, and each diaper 100 of the integrated body 11 'constituting the lower stage 82 has the front and rear body parts 100F and 100B on the lower side. It is. As described above, the diaper 100 has a smaller thickness than other parts because the absorbent body 103 is not disposed in the waist portions 107F and 107B of the front and rear bodies 100F and 100B. It becomes more prominent by folding. Therefore, in such a packaging form, when a user (for example, a mother) takes out the diaper 100 from the packaging bag 83, a step is formed in a portion where the user holds the diaper, so that the user can easily grasp and take out. There is. In addition, when the packaging body 80A is erected in such a packaging form, there is also an advantage that it is easy to display because the planar shape seen from the upper surface is rectangular.

  In addition, as shown in FIG. 7, the stacks 11 fed into the stack rotation means 40 can be rotated 180 ° around the axis N in the pressing direction by every other plate 41. That is, the stack rotating means 40 rotates the stack 11 by 180 ° by the plate 41 to change the direction to the stack 11 ', and sends it to the stack stage number forming means 50 as the next means, and then rotates the stack. The stack 11 fed to the means 40 and the stack 11 fed to the stack rotating means 40 next are passed through the stack 11 without being rotated by the plate 41 to form the stack number. It can also be set to send to the means. Thereby, a package 80B having a packaging form composed of three stages of an upper stage 81, a middle stage 87, and a lower stage 82 as shown in FIG. 8 can be formed.

  The stacked bodies 11, 11 ′ that have passed through the stacked body rotating means 40 are transferred to the stacked body stage number forming means 50 according to the conveyor 12 and sent in. In this case, the stack number forming means 50 is set so that the fed stacks 11 and 11 'are taken out three by three in the order in which they are fed and stacked in three stages. Specifically, it is set to take out three stacks in the order of the stack 11, the stack 11 ′, and the stack 11 sent to the stack level forming means 50 and stack them in three levels. Yes. As a result, a packaging body 80B having a packaging form composed of three stages, that is, an upper stage 81 composed of the aggregate 11, an intermediate stage 87 composed of the aggregate 11 ', and a lower stage 82 composed of the aggregate 11 is formed. Can do.

  As described above, according to the package forming apparatus 10, the package 80 </ b> B having a packaging form including the upper stage 81, the middle stage 87, and the lower stage 82 can be formed without adding new equipment.

  In addition, as shown in FIG. 8, in the package 80B, each diaper 100 of the integrated body 11 constituting the upper stage 81 has the front and rear body parts 100F and 100B as the upper side, and each diaper 100 of the integrated body 11 constituting the lower stage 82 is bent. It is formed in a packaging form with the portion 112 on the lower side. Therefore, as described above, when sealing the bottom portion 84 of the packaging bag 83, the lower part of each diaper 100 constituting the lower stage 82 can be prevented from being sealed together with the packaging bag 83, and the diaper When 100 is taken out from the packaging bag 83, there is an advantage that it becomes easy to take out.

  Furthermore, according to the package forming apparatus 10, the upper stage 81 is configured by the stacked body 11 ′ rotated by the stacked body rotating means 40, and the middle stage 87 is formed by the stacked body 11 not rotated by the stacked body rotating means 40. By configuring the lower stage 82 with the integrated body 11 ′ rotated by the integrated body rotating means 40, a package 80 </ b> C having a packaging form as shown in FIG. 9 can be formed. In such a packaging form, as described above, when the bottom 84 of the packaging bag 83 is sealed, the upper part of the integrated body 11 ′ constituting the upper stage 81 is not easily crushed, so the feces pocket provided in the diaper 100 105 can be prevented from being deformed, and when the package 80C is erected, there is an advantage that it is easy to display because the planar shape seen from the upper surface is rectangular.

  As described above, according to the absorbent article packaging body forming apparatus 10 according to the present invention, it is possible to change the direction by rotating the integrated body 11 by 180 degrees by the integrated body rotating means 40 every predetermined number without manually. it can. Therefore, it is possible to form a package having various forms of packaging without increasing the equipment space of the package forming apparatus 10.

  As mentioned above, although one Embodiment of the content of the package forming apparatus of the absorbent article which concerns on this invention was described, this invention can change the structure into various things as follows.
