Description

  TECHNICAL FIELD The present invention relates to an absorbent article manufacturing apparatus and an absorbent article manufacturing method for laminating a liquid absorbent material in a mold and molding an absorbent body.

  Patent Document 1 discloses an absorbent article having an absorbent body molding mechanism in which a molding die in which a concave portion formed from a predetermined surface is formed is conveyed in a predetermined direction, and a liquid absorbent material is laminated in the concave portion to form an absorbent body. A manufacturing apparatus is disclosed. This manufacturing apparatus for absorbent articles includes a fiber distribution duct that distributes fibers as liquid absorbent materials into the recesses, and a plurality of polymer input members that input a superabsorbent polymer into a mold.

  The polymer charging members are arranged at intervals in the crossing direction orthogonal to the conveying direction of the mold. According to the absorbent article manufacturing apparatus configured as described above, the superabsorbent polymer can be supplied into the recesses through the polymer charging member, and the fibers can be supplied into the recesses through the gap between the polymer charging members. . Therefore, it is possible to manufacture an absorbent body in which a superabsorbent polymer and fibers are mixed.

(3) Configuration of Absorbent Article Manufacturing Apparatus Next, the configuration of the absorbent article manufacturing apparatus 100 according to the present embodiment will be described. The absorbent article manufacturing apparatus 100 is an absorbent article manufacturing apparatus used in the above-described absorbent material supply process, absorbent body forming process, conveying process, pressing process, sheet bonding process, and cutting process.

  The absorbent article manufacturing apparatus includes an absorbent material supply mechanism 110, an absorbent body forming mechanism 120, a transport mechanism 130, a press mechanism 140, a sheet joining mechanism 150, and a cutting mechanism 160. Absorbent article manufacturing apparatus 100 is an apparatus for manufacturing an absorbent body having a slit.

  The absorbent material supply mechanism 110 supplies pulp and SAP as a liquid absorbent material toward the absorbent body forming mechanism 120. The absorbent material supply mechanism 110 includes a supply duct 111 that guides pulp and SAP toward the mold of the absorber molding mechanism 120. The supply duct 111 has an opening 112 that opens toward the absorber molding mechanism 120. The supply duct 111 is configured to discharge and supply mixed air containing pulverized pulp. The opening 112 constitutes a pulp supply port.

  A plurality of polymer charging pipes 114 for supplying SAP are provided in the supply duct 111. The plurality of polymer charging pipes 114 are arranged adjacent to the cross direction CD. An opening 115 that forms a polymer supply port that guides the SAP toward the absorber molding mechanism 120 is formed at the tip of each polymer charging tube.

  The absorber molding mechanism 120 is a lamination drum in which a molding die 121 that rotates around a rotation shaft 120a and laminates an absorber on the outer peripheral surface thereof is disposed. The molding die 121 has a recess 122 that is recessed from a predetermined surface. The lamination drum conveys the molding die 121 in a predetermined direction, and laminates pulp and SAP supplied from the absorbent material supply mechanism 110 in the recess 122 to form an absorbent body. A plurality of molds of the absorber molding mechanism 120 are provided and are adjacent along the circumferential direction of the laminated drum. The recesses 122 of the adjacent molds 121 communicate with each other.

  As shown in FIG. 3, the outer shape of the recess 122 of the mold 121 corresponds to the outer shape of the absorber 30. As shown in FIG. 4, the molding die 121 is provided at a position corresponding to the laminated region R1 where the liquid absorbent material is laminated and the slit formed in the absorber, and is not laminated with the liquid absorbent material. And R2.

  The laminated region R1 is a portion where a space for laminating a liquid absorbent material is formed, and the non-laminated region R2 is a portion where a space for laminating a liquid absorbent material is not formed. This is a portion where a convex portion 123 is formed that protrudes from the bottom surface of the concave portion toward the radially outer side of the laminated drum. Since the non-laminated region has a convex portion, the liquid absorbent material is not laminated on the portion. The non-stacked region is provided at a position corresponding to the slit 31 of the absorber 30.

  Further, the non-stacked region R2 is arranged so as to be shifted from the polymer supply port in the cross direction CD. Therefore, SAP is not supplied to the region where the non-stacked region R2 is provided and the region extending in the transport direction from the non-stacked region, but only the pulp is supplied. On the other hand, the pulp supply port is arranged to face the laminated region and the non-laminated region. Therefore, pulp and SAP are supplied to the region where the stacked region R1 is provided.

  A suction mechanism (not shown) that sucks the liquid absorbent material stacked in the recesses and places the inside of the mold in a negative pressure state of −0.5 KPa to −2.0 KPa, radially inward of the mold. Is provided. The diameter of the lamination drum is 800 mm to 1600 mm, and the flow rate of the fibers laminated in the recesses is 10 m / S to 35 m / S. Suction negative pressure of drum internal (suction) negative pressure is -5 to -14KPa.

  According to the absorbent body forming mechanism 120 configured as described above, it is possible to continuously manufacture an absorbent body having a predetermined outer shape while forming a slit.

  The conveyance mechanism 130 includes a first sheet conveyance unit 131 that conveys the first sheet material below the absorber forming mechanism 120. The absorbent body forming mechanism 120 arranges the continuous absorbent body 33 on the first sheet material 51. FIG. 3 shows a state in which the continuous absorbent 33 is disposed on the first sheet material 51.

  The conveyance mechanism 130 includes a second sheet conveyance unit 132 that conveys the second sheet material 52 on the downstream side in the conveyance direction with respect to the absorbent body forming mechanism 120. The 2nd sheet conveyance part 132 arrange | positions a 2nd sheet material so that the continuous absorber 33 on a 1st sheet material may be covered. By supplying the first sheet material and the second sheet material by the transport mechanism, the continuous absorbent body 33 can be protected by the sheet material, and the continuous absorbent body 33 can be prevented from being deformed.

  The press mechanism 140 has a pair of press rolls 141 and 142 that are located on the downstream side in the transport direction with respect to the second sheet transport unit 132 and are arranged to face each other. The press mechanism 140 presses the continuous absorbent body sandwiched between the first sheet material and the second sheet material in the thickness direction. Specifically, a continuous absorbent body sandwiched between sheet materials is passed between a pair of press rolls, and the continuous absorbent body is pressed in the thickness direction.

  The sheet joining mechanism 150 joins the sheet materials arranged with the continuous absorber 33 interposed therebetween. The sheet materials may be bonded to each other via an adhesive applied to the first sheet material or the second sheet material, or may be bonded by thermal welding or ultrasonic welding. By the sheet material joining mechanism, the first sheet material and the second sheet material can be joined at the position of the slit of the absorber.

  In the present embodiment, an adhesive application mechanism (not shown) for applying an adhesive to at least one of the absorber-side surface of the first sheet material and the absorber-side surface of the second sheet material is further provided. And the sheet material is joined to each other through the adhesive applied by the adhesive application mechanism.

  The cutting mechanism 160 has a cutter roll 161 and an anvil roll 162 that are located on the downstream side in the transport direction from the sheet joining mechanism 150 and are disposed to face each other. The cutting mechanism 160 cuts the continuous absorbent body sandwiched between the first sheet material and the second sheet material along the width direction, and forms the absorbent body 30 corresponding to each product.

(4) Action / Effect In the absorbent material supply mechanism according to the present embodiment, the polymer supply port for supplying the SAP is shifted from the non-stacked region R2 in the crossing direction. Is not supplied. On the other hand, since the pulp supply port is disposed to face the laminated region and the non-laminated region, the pulp can be supplied to the entire laminated region and the non-laminated region. Therefore, an absorber can be shape | molded, without arrange | positioning SAP in the position corresponding to a slit, laminating | stacking a pulp on the whole recessed part.

  Moreover, a 1st sheet material and a 2nd sheet material can be joined in the position of the slit of the absorber shape | molded in this way. Since the SAP is not disposed in the slit, the sheet material can be joined and the displacement of the absorber can be suppressed. Since the absorbent body formed in this manner has slits formed at correct positions in the design, it can be deformed through the slits in the same manner as in the design.

  Furthermore, since a plurality of polymer supply ports are provided at intervals in the crossing direction, the polymer supply ports can be arranged corresponding to the regions between the slits or the regions adjacent to the slits. The absorber can be molded without arranging SAP.

  Since the convex portion 123 is formed in the concave portion 122 of the mold, the slit corresponding to the shape of the convex portion can be formed in the non-laminated region R2. Moreover, since the convex portion is formed, it is possible to prevent the SAP from being disposed in the slit even when the SAP is unintentionally supplied to the non-stacked region.

  Since it further includes an adhesive application mechanism that applies an adhesive to at least one of the absorber-side surface of the first sheet material and the absorber-side surface of the second sheet material, the first sheet is interposed via the adhesive. The material and the second sheet material can be joined. Since the adhesive is applied, the first sheet material and the second sheet material can be joined by pressing the first sheet material or the second sheet material.

  In order to further include a press mechanism for pressing the absorber in the thickness direction on the upstream side in the conveyance direction from the sheet bonding mechanism, by pressing the absorber before bonding the sheet at a position corresponding to the slit of the absorber, The shape of the absorber can be hardened. Therefore, it is possible to prevent the absorber from collapsing when the first sheet material and the second sheet material are joined.

  Further, for example, when the basis weight of the absorbent body is increased, the continuous absorbent body 33 formed by the absorbent body forming mechanism 120 becomes thick, and it may be difficult to join only the slit portion in the sheet joining process. However, by performing the pressing step before the sheet bonding step, the thickness of the absorber can be suppressed within a predetermined range, and the sheet materials can be bonded at positions corresponding to the slit portions.

  Further, the pulp is supplied to the lamination drum together with air, and is laminated in the mold in a region where the supply duct and the outer peripheral surface of the lamination drum are opposed to each other. On the other hand, SAP is granular and has a higher density than pulp, and drops from the polymer supply port and is laminated in the mold. The area where the pulp is laminated in the mold is an area where the supply duct and the outer peripheral surface of the lamination drum face each other, but the area where the SAP is laminated in the mold is directly below the polymer supply port and in the conveying direction. Downstream.

  The polymer supply port is arranged at the center in the conveying direction of the pulp supply port. Since the polymer supply port is arranged at the center in the conveying direction of the pulp supply port, the pulp is supplied before and after supplying the SAP. Therefore, pulp can be arrange | positioned to the lower layer and upper layer of SAP, and an absorber can be formed in 3 layer structure.

  Furthermore, by disposing the pulp in the lower layer and upper layer of the SAP, it is possible to prevent the SAP from rolling from the absorber surface and dropping into the slit. Further, the SAP can be retained in the absorbent body, and the SAP can be prevented from falling off through the top sheet, thereby preventing adhesion to the skin.

  If the distance between the polymer supply port and the mold is too long, the SAP supplied from the polymer supply port may unintentionally enter the non-laminated region. However, since the distance between the polymer supply port and the mold is 10 mm to 100 mm, the SAP can be arranged at the intended location.
