201207182 1開口部63與第2開口部73完全一致的情形比較’通過第2 網眼皮帶70的水蒸汽的速度降低。因此，藉由通過第2網 眼皮帶70的水蒸汽，可防止連續層積體20的芯材通過第2 連續薄片掉落的情況。 芯材之中，尤其是超吸收性聚合物粒子其粒徑小’但 是藉由使水蒸汽的速度在第2連續薄片22側降低，可防止 掉落的情況。絨毛漿13a的纖維長，其平均約0.5〜20.0mm ，超吸收性聚合物粒子的平均粒徑是數nm〜約3 mm。作爲 該等芯材，可使用在該領域所使用的一般者。又，藉由將 第2網眼皮帶70的開口設定的比超吸收性聚合物粒子的平 均粒徑更小，可防止超吸收性聚合物粒子從第2網眼皮帶 70掉落的情況。因此，萬一，在第2連續薄片22與第2網眼 皮帶70之間有超吸收聚合物粒子存在，也可防止該粒子通 過第2網眼皮帶70掉落到吸引手段90的情況。 如上述，藉由對連續層積體2 0噴射水蒸汽，可將芯13 朝其厚度方向壓縮，使連續層積體20全體變薄。從噴射部 8 0a所噴射的水蒸汽會有不含水分的乾的蒸汽、飽和蒸汽 、或含有水分的濕的蒸汽的情況。水蒸汽爲濕的蒸汽或飽 和蒸汽時，可容易使親水性纖維成爲濕潤狀態並變形。乾 的蒸汽，是可使包含在親水性纖維的水分氣化，而可以氣 化的水分使親水性纖維的變形變的容易。又，親水性纖維 若爲熱可塑性合成纖維，可藉由帶有乾的蒸汽的熱，使其 熱可塑性合成纖維的變形變的容易。在藉由高壓的水蒸汽 所壓縮的連續層積體，親水性纖維之例如絨毛漿在加熱/ -12- 201207182 加濕狀態或加熱狀態下快速地變形，而失去對第1及第2網 眼皮帶60、70所爲的壓縮力的反抗力，容易保持被壓縮之 後的形狀。 在上述這類的連續層積體20，在第1及第2連續薄片21 、22的任一方使用塑膠薄膜時，由於被噴射的水蒸汽必須 通過該等，所以塑膠薄膜至少具有水蒸汽可通過的複數個 孔爲理想。 在上述被壓縮的連續層積體20，從第1及第2網眼皮帶 60、70移行到搬送輥30，以刀具31沿著朝交叉方向CD延伸 的切斷線被切斷》切斷線位在鄰接的芯13之間。藉由如此 的切斷方式，可獲得如圖1例示的這類的層積體10。 在圖7、8，表示第1及第2網眼皮帶60、70的其他的例 子。如圖示，第1網眼皮帶60、與第2網眼皮帶70，其開口 率不同，第1開口部63被設成比第2開口部73更小。如此將 第1及第2網眼皮帶60、70的開口率設成不同的方式，由於 第2非開口部74容易重疊在任一個第1開口部63，所以沒有 必要爲了重疊第1開口部63與第2非開口部74，嚴密的使第 1網眼皮帶60與第2網眼皮帶70的層積位置對齊。 作爲第1網眼皮帶可使用9網孔、開口率約56%、線徑 約0.8 5mm者。作爲第2網眼皮帶可使用6網孔、開口率約 6 5 %、線徑約〇 . 8 5 m m者。 藉由加大吸引手段90的位置的第2網眼皮帶70的第2開 口部73，可防止吸引力的降低。藉由加大吸引側的開口部 ’因而可確保吸引面積。在該實施形態，雖將第1開口部 -13- 201207182 63與第2開口部73的形狀做成相同的略矩形，可是該等也 可具有圓形等的其他的形狀，也可具有互相不同的形狀。 具有互相不同的形狀時，第2非開口部74容易重疊在第1開 口部 63。 <第2實施形態> 圖9表示其他的例子的層積體處理裝置者。該實施形 態中，層積體處理裝置具有複數噴射手段80及吸引手段90 。其他的構造由於與第1實施形態同樣，所以針對同樣.的 構成要素，使用與第1實施形態相同的符號，並省略其詳 細的說明。 在第1網眼皮帶60的並行行走部62，使兩個噴射手段 80在機械方向MD分開安裝。形成並行行走部62的第1輥 61 a及第2輥61b，是位在兩個噴射手段80的機械方向MD外 側，第1網眼皮帶60是以圍著該等噴射手段80的外側的方 式旋轉。 在第1網眼皮帶60的上下方向TD的下方，與兩個噴射 手段80分別對應的吸引手段90在機械方向MD分離配置。 第2網眼皮帶，是對應兩個吸引手段的各手段安裝兩個， 分別藉由第2皮帶搬送手段71旋轉。 根據上述這類的構成，在連續層積體20，藉由兩個噴 射手段80，在機械方向MD的兩處噴射水蒸汽。由於連續 層積體20是兩次被壓縮，所以與利用一處的噴射手段進行 壓縮時相比，可縮小水蒸汽的噴出壓。因此，噴射手段80 -14- 201207182 可使用比較廉價，對應小型的低壓力者。又，由於可縮小 噴出壓，所以連續層積體20的芯材不易通過第2連續薄片 22 ° 由於第2網眼皮帶70是做成分離的兩個旋轉皮帶，所 以在該等兩網眼皮帶70的第2開口部73的位置關係，與第1 網眼皮帶60的第1開口部63的位置關係相同的情況幾乎不 可能。亦即，複數個個別的第2網眼皮帶的第2開口部73， 皆與第1開口部63完全一致的情況幾乎不可能，至少可在 任一方將第2非開口部74設成位在第1開口部63。因此，不 必要嚴密的調整該等第1及第2網眼皮帶60、70的位匱關係 〇 在被挾持在第1及第2網眼皮帶60、70的連續層積體20 ，在第1非開口部64及第2非開口部74重疊的部分，可能會 一部分阻礙水蒸汽的流動，在作用的壓力產生不均。可是 ，在機械方向MD分開的兩個第2網眼皮帶70，相對於連續 層積體20，由於第2開口部73及第2非開口部74的位置一致 的情形幾乎沒有，所以在上游的第2網眼皮帶70，即使是 重疊在第2非開口部74的連續層積體20部分，也會在下游 的第2網眼皮帶70，重疊在第2開口部73，藉由使用該等兩 個第2網眼皮帶70，可使水蒸汽幾乎均等的作用在連續層 積體20的全體。 <第3實施形態> 圖10表示其他的例子的層積體處理裝置。在該實施形 -15- 201207182 態，層積體處理裝置具有複數個噴射手段80及吸引手段90 。其他的構成由於與第1實施形態同樣’所以關於同樣的 構成要素，使用與第1實施形態相同的符號’並省略其詳 細的說明。 噴射手段80在機械方向MD分開配置兩個。以與各個 噴射手段80對應的方式，第1網眼皮帶60也配置兩個，藉 由各個第1皮帶搬送手段61，以在噴射手段80的周圍旋轉 的方式設置。噴射手段80是以與各並行行走部72對向的方 式被安裝。 在噴射手段80，各個吸引手段90對向配置》1個第1網 眼皮帶60在該等兩個吸引手段90的周圍可旋轉地被安裝。 第1網眼皮帶60是藉由第1皮帶搬送手段61被旋轉，並且位 在與並行行走部62對向的位置。 在第1網眼皮帶60的並行行走部62，使兩個噴射手段 80在機械方向MD分開安裝。形成並行行走部62的第1輥 61a及第2輥61b，是位在兩個噴射手段80的機械方向MD外 側，第1網眼皮帶6 0是以圍繞該等噴射手段8 〇的外側的方 式旋轉。 根據上述這類的構成，由於在機械方向MD的兩處噴 射水蒸汽’所以可獲得與第2實施形態同樣的效果（參閱 段落003 7 )。又’由於第！網眼皮帶6〇是做成分開的兩個 旋轉皮帶’所以與第2開口部73的位置關係的調整容易， 第1非開口部64造成的水蒸汽不均的防止等，可獲得與第2 實施形態同樣的效果（參閱段落〇〇38及〇〇39) ^ •16- ⑧ 201207182 在第2及第3實施形態，雖是設成具備兩個噴射手段80 及吸引手段90，可是，這個也可爲三個以上。又，第1網 眼皮帶60及第2網眼皮帶70的任一個皮帶在機械方向MD分 開安裝有複數個即可。又，也包含第1網眼皮帶60及第2網 眼皮帶70皆在機械方向MD分開安裝有複數個者。 在第1〜第3實施形態，雖將第1及第2網眼皮帶60、70 作爲旋轉皮帶，可是並不限於此，也可爲朝機械方向MD 延伸的直線狀的皮帶。可是，藉由做成旋轉皮帶，可謀求 裝置整體的小型化。又，雖是在第1連續薄片21與第2連續 薄片22之間配置有芯13，可是至少只要有配置芯13的第2 連續薄片22，則第1連續薄片2 1並不是必須的構成。 以上的實施形態中，可在一個實施形態附加其他的實 施形態的要素、構成或是組合。本發明的說明書及專利申 請範圍中，用語「第1」「第2」…「第8」只是爲了區別 同名稱的要素、位置等所使用。 【圖式簡單說明】 [圖1]層積體的一部分的撕破俯視圖。 [圖2]爲圖1的ll-π線的剖視圖。 [圖3]第1實施形態的層積體處理裝置的說明圖。 [圖4]第1及第2網眼皮帶的說明圖。 [圖5]第1及第2網眼皮帶的一部分放大圖。 [圖6 ]爲圖5的VI -

On the circumferential surface of the suction cylinder 40, the concave portions 41 which substantially coincide with the planar shape of the core 13 of the laminated body 10 (see Fig. 1) are formed at a desired pitch in the circumferential direction. -8 - 8 201207182 The core material supply means 50 has a cover portion 51 formed to cover the suction tube 40, and includes a pulp supply portion 52 for supplying the fluff pulp 13a of the hydrophilic fibers; and a superabsorbent polymerization supply The polymer particle supply unit 53 for the material particles 13b. The core material is supplied from the pulp supply unit 52 and the polymer particle supply unit 53 toward the concave portion 41 of the suction tube 40. In the concave portion 41 of the suction tube 40, the suction by the vacuum pressure is applied, but since the first continuous sheet 2 is positioned on the circumferential surface thereof, the first continuous sheet 21 is deformed along the concave portion 41 and deformed therein. The core material is partially introduced, and the core 13 is formed in a shape corresponding to the concave portion 41. The first continuous sheet 21 on which the core 13 is formed is separated from the circumferential surface of the suction tube 40, moved to the downstream conveyance roller 30, and travels in the machine direction MD. On the first continuous sheet 21, the core 13 is in the machine direction. The MDs are arranged intermittently. On the first continuous sheet 21, the second continuous sheet 22 is continuously supplied and sandwiched between the cores 13. The core 13 is held by the first continuous sheet 21 and the second continuous sheet 22 to form a continuous laminate 20. The continuous laminate 20 is conveyed in the machine direction MD by the conveyance roller 30, and is held by the air-permeable first and second mesh belts 60 and 70. The first mesh belt 60 is positioned above the plane of the vertical direction TD of the continuous laminate 20, i.e., on the side of the ejection means 80. The second mesh belt 70 is positioned below the plane of the vertical direction TD of the continuous laminate 20, that is, on the suction means 90 side. The first and second mesh belts 60 and 70 are rotary belts that are annularly rotated by the first and second belt conveyance means 61 and 71. The first belt conveying means 61 has a first roller 61a and a second roller 61b which are parallel to the machine direction MD, and third and fourth portions which are positioned above the vertical direction TD of the first and second rollers 61a and 61b. The rollers 61c, -9 - 201207182 61d' the first mesh belt 60 rotates clockwise on the outside of the rollers. The second belt transporting means 71 has a fifth light 71a and a sixth light 71b which are positioned in parallel with the machine direction MD, and a seventh roller 71c which is positioned below the vertical direction TD of the fifth and sixth light 71a, 71b. The eighth roller 71d rotates the second mesh belt 70 counterclockwise on the outer side of the rollers. As shown in FIGS. 3 and 4, the first and second mesh belts 60 and 70 have parallel walking between the first and second rolls 61a and 61b and between the fifth and sixth rolls 71a and 71b. Parts 62, 72. In the parallel traveling portions 62, 72, the continuous laminate 20 is compressed in the thickness direction and conveyed in the machine direction MD. Further, the continuous laminate 20 is not limited to being compressed in the thickness direction by the first and second mesh belts 60, 70, and may be conveyed in the machine direction MD without being compressed and held. An ejection means 80 for injecting water vapor is disposed above the vertical direction TD of the parallel traveling portion 62 of the first mesh belt 60. In the spraying means 80, the boiler 801 which generates steam by a temperature equal to or higher than the boiling point of water is pressurized with water vapor by the pressure control means 82 to supply high-pressure steam to supply steam. The injection means 80 has an injection portion 80a that ejects water vapor supplied from the pressure control device 82 toward the first mesh belt 60, and the injection portion 80a is arranged in a plurality of positions in the intersecting direction CD intersecting the machine direction MD (not shown). formula). The ejection portion 80a is, for example, a nozzle having a diameter of 0.1 to 2.0 mm, 0.5 to 10.0 mm, preferably 0.5 to 5.0 mm, more preferably 0.5 to 3.0 mm in the intersecting direction C D . In the vertical direction TD of the parallel traveling portion 72 of the second mesh belt 70, a suction means 90 for sucking a suction box or the like of the water vapor sprayed from the injection portion 80a is attached to -10- 8 201207182. Therefore, the water vapor sprayed from the injection portion 80a is sucked by the suction means 90 through the first mesh belt 60, the continuous laminate 20, and the second mesh belt 70. The amount of water vapor injected from the injection portion 80a can be adjusted according to the traveling speeds of the first and second mesh belts 60, 70, and the first and second mesh belts 60, 70 are driven at about 5 to 500 m/min. In this case, it is preferred to carry out the spraying in the range of about 1.23 kg/m 2 to 0.03 kg/m 2 with respect to the surface area of the continuous laminate 20 . As the first and second mesh belts 60 and 70, a mesh belt made of a metal wire made of a stainless steel alloy or bronze, or a mesh belt made of plastic such as polyester fiber or amide fiber can be used. a metal belt or the like formed of a perforated metal plate. As shown in FIGS. 5 and 6, the first and second mesh belts 60 and 70 have a plurality of first and second opening portions 63 and 73, and are located in the first and second opening portions 63 and 73, respectively. The first and second non-opening portions 64 and 74 between the positions. The first and second mesh belts 60 and 70 can be used in a range of about 2 to 600 meshes. The wire diameter is set to be about 0.03 to 5.0 mm, and the aperture ratio is set to be about 10 to 85%. The first and second opening portions 63 and 73 are formed in a substantially rectangular shape. The first and second mesh belts 60 and 70 are disposed in parallel with each other in the parallel traveling portions 62 and 72, that is, at least in the portion of the injection portion 80a, and are disposed so as to be shifted from each other. 2 The opening portion 73 does not have a completely identical situation. That is, in the first opening portion 63, the second non-opening portion 724 is overlapped, and a part of the first opening portion 633 is closed by the second non-opening portion 744. The water vapor to be ejected in the manner described above passes through the first mesh portion 70 of the first mesh belt 6A and compresses the continuous laminate 20 in the thickness direction to pass through the second mesh belt 70. Since the first opening portion 63 overlaps with the second non-opening portion 74, the speed of the water vapor passing through the second mesh belt 70 is compared with the case where the opening portion 63 and the second opening portion 73 of the -11 - 201207182 1 completely match each other. reduce. Therefore, by the water vapor passing through the second mesh belt 70, the core material of the continuous laminate 20 can be prevented from falling through the second continuous sheet. Among the core materials, in particular, the superabsorbent polymer particles have a small particle size, but by lowering the speed of the water vapor on the second continuous sheet 22 side, it is possible to prevent the falling. The fiber length of the fluff pulp 13a is about 0.5 to 20.0 mm on average, and the average particle diameter of the superabsorbent polymer particles is from several nm to about 3 mm. As the core materials, those generally used in the field can be used. Further, by setting the opening of the second mesh belt 70 to be smaller than the average particle diameter of the superabsorbent polymer particles, it is possible to prevent the superabsorbent polymer particles from falling from the second mesh belt 70. Therefore, in the case where superabsorbent polymer particles are present between the second continuous sheet 22 and the second mesh belt 70, it is possible to prevent the particles from falling to the suction means 90 through the second mesh belt 70. As described above, by spraying water vapor to the continuous laminate 20, the core 13 can be compressed in the thickness direction thereof to make the entire continuous laminate 20 thin. The water vapor injected from the injection portion 80a may be dry steam containing no moisture, saturated steam, or wet steam containing moisture. When the water vapor is wet steam or saturated steam, the hydrophilic fibers can be easily wetted and deformed. The dry steam is such that the water contained in the hydrophilic fibers can be vaporized, and the water that can be vaporized can easily deform the hydrophilic fibers. Further, if the hydrophilic fiber is a thermoplastic synthetic fiber, the deformation of the thermoplastic synthetic fiber can be easily facilitated by heat with dry steam. In a continuous laminate compressed by high-pressure water vapor, a hydrophilic fiber such as fluff pulp is rapidly deformed under heating/-12-201207182 humidification or heating, and loses the first and second mesh skins. The resistance of the compressive force of the belts 60 and 70 is easy to maintain the shape after being compressed. In the continuous laminate 20 of the above type, when the plastic film is used in either of the first and second continuous sheets 21, 22, since the water vapor to be sprayed must pass through, the plastic film has at least water vapor to pass through. The multiple holes are ideal. The compressed continuous laminate 20 is transferred from the first and second mesh belts 60 and 70 to the transport roller 30, and the cutter 31 is cut along the cutting line extending in the intersecting direction CD. Positioned between adjacent cores 13. By such a cutting method, the laminate 10 of the type illustrated in Fig. 1 can be obtained. Other examples of the first and second mesh belts 60, 70 are shown in Figs. As shown in the figure, the first mesh belt 60 and the second mesh belt 70 have different aperture ratios, and the first opening portion 63 is formed to be smaller than the second opening portion 73. In this way, the opening ratio of the first and second mesh belts 60 and 70 is different, and the second non-opening portion 74 is likely to be superimposed on any one of the first openings 63. Therefore, it is not necessary to overlap the first opening 63 and The second non-opening portion 74 closely aligns the laminated positions of the first mesh belt 60 and the second mesh belt 70. As the first mesh belt, 9 mesh holes, an opening ratio of about 56%, and a wire diameter of about 0.8 5 mm can be used. As the second mesh belt, 6 mesh holes, an aperture ratio of about 6 5 %, and a wire diameter of about 8.5 mm are used. By increasing the second opening portion 73 of the second mesh belt 70 at the position of the suction means 90, it is possible to prevent a decrease in the attractive force. The suction area can be secured by increasing the opening portion on the suction side. In this embodiment, the first opening 13-201207182 63 and the second opening 73 have the same rectangular shape, but these may have other shapes such as a circular shape, or may be different from each other. shape. When the shapes are different from each other, the second non-opening portion 74 is likely to overlap the first opening portion 63. <Second Embodiment> Fig. 9 shows a laminate processing apparatus of another example. In this embodiment, the laminate processing apparatus has a plurality of ejection means 80 and a suction means 90. The other components are the same as those in the first embodiment, and the same reference numerals are used for the same components as in the first embodiment, and the detailed description thereof will be omitted. In the parallel running portion 62 of the first mesh belt 60, the two spraying means 80 are separately mounted in the machine direction MD. The first roller 61 a and the second roller 61 b forming the parallel traveling portion 62 are located outside the machine direction MD of the two injection means 80, and the first mesh belt 60 is disposed around the outside of the ejection means 80. Rotate. Below the vertical direction TD of the first mesh belt 60, the suction means 90 corresponding to each of the two injection means 80 are disposed apart from each other in the machine direction MD. The second mesh belt is attached to each of the means corresponding to the two suction means, and is rotated by the second belt conveyance means 71. According to the above configuration, in the continuous laminate 20, water vapor is ejected in two places in the machine direction MD by the two injection means 80. Since the continuous laminate 20 is compressed twice, the discharge pressure of the water vapor can be made smaller than when the compression is performed by one of the injection means. Therefore, the spraying means 80 - 14 - 201207182 can be used relatively inexpensively, corresponding to a small, low-pressure person. Further, since the discharge pressure can be reduced, the core material of the continuous laminate 20 is less likely to pass through the second continuous sheet 22°. Since the second mesh belt 70 is a separate two rotating belts, the two mesh belts are provided. The positional relationship between the second opening portion 73 of 70 is almost the same as the positional relationship of the first opening portion 63 of the first mesh belt 60. In other words, it is almost impossible for the second opening portions 73 of the plurality of individual second mesh belts to completely match the first opening portion 63, and at least one of the second non-opening portions 74 may be positioned at least. 1 opening portion 63. Therefore, it is not necessary to closely adjust the positional relationship between the first and second mesh belts 60, 70, and the continuous laminate 20 held by the first and second mesh belts 60, 70, in the first The portion where the non-opening portion 64 and the second non-opening portion 74 overlap may partially block the flow of the water vapor, and the pressure applied may be uneven. However, the two second mesh belts 70 that are separated in the machine direction MD have almost no position in the second opening portion 73 and the second non-opening portion 74 with respect to the continuous laminate 20, so that they are upstream. Even if the second mesh belt 70 is overlapped in the continuous laminate 20 of the second non-opening portion 74, the second mesh belt 70 on the downstream side is superposed on the second opening portion 73, and the use of the second mesh belt 70 is performed by using the second opening portion 73. The two second mesh belts 70 can cause water vapor to act almost uniformly on the entire continuous laminate 20. <Third Embodiment> Fig. 10 shows a laminate processing apparatus of another example. In the embodiment -15-201207182, the laminate processing apparatus has a plurality of ejection means 80 and suction means 90. The other components are the same as in the first embodiment. Therefore, the same reference numerals are used for the same components as in the first embodiment, and detailed description thereof will be omitted. The spraying means 80 are arranged in two in the machine direction MD. Two first mesh belts 60 are disposed in correspondence with the respective ejection means 80, and are provided so as to be rotatable around the ejection means 80 by the respective first belt conveyance means 61. The spraying means 80 is attached in such a manner as to face each of the parallel traveling portions 72. In the spraying means 80, each of the first suction belts 60 is rotatably mounted around the two suction means 90. The first mesh belt 60 is rotated by the first belt conveyance means 61 and is positioned at a position opposed to the parallel traveling portion 62. In the parallel running portion 62 of the first mesh belt 60, the two spraying means 80 are separately mounted in the machine direction MD. The first roller 61a and the second roller 61b forming the parallel traveling portion 62 are located outside the machine direction MD of the two injection means 80, and the first mesh belt 60 is surrounded by the outer side of the ejection means 8 Rotate. According to the configuration described above, since the water vapor is ejected at two places in the machine direction MD, the same effect as in the second embodiment can be obtained (see paragraph 003 7). And because of the first! Since the mesh belt 6 is a separate two rotating belts, the positional relationship with the second opening 73 is easily adjusted, and the water vapor unevenness caused by the first non-opening portion 64 is prevented. The same effect of the embodiment (see paragraphs 〇〇38 and 〇〇39) ^ •16- 8 201207182 In the second and third embodiments, the two injection means 80 and the suction means 90 are provided, but this is also Can be more than three. Further, any one of the first mesh belt 60 and the second mesh belt 70 may be attached to the plurality of belts in the machine direction MD. Further, a plurality of the first mesh belt 60 and the second mesh belt 70 are also mounted in the machine direction MD. In the first to third embodiments, the first and second mesh belts 60 and 70 are used as the rotating belt, but the present invention is not limited thereto, and may be a linear belt extending in the machine direction MD. However, by forming a rotating belt, it is possible to reduce the size of the entire apparatus. Further, although the core 13 is disposed between the first continuous sheet 21 and the second continuous sheet 22, the first continuous sheet 2 1 is not necessarily required as long as at least the second continuous sheet 22 in which the core 13 is disposed. In the above embodiments, elements, configurations, or combinations of other embodiments may be added to one embodiment. In the specification and patent application scope of the present invention, the terms "1st", "2nd", and "8th" are used only to distinguish elements and positions of the same name.
