又，於專利文獻2中記載有如下技術：於集聚用凹部（吸 引堆積部）之底面部上設置有開口面積率（吸引部開孔面積 率）不同之複數個吸引區域，製造基重局部不同之吸收 體。 先前技術文獻 專利文獻 160798.doc 201231026 專利文獻1 :日本專利特開2000-178866號公報 專利文獻2 :日本專利特開2004-65930號公報 【發明内容】 而於專利文獻1之技術中，為變更所製造之吸收體 之形狀而需要進行變更旋轉筒内之吸引腔室之隔壁之配置 等大規模的作業，從而無法靈活地應對吸收體之規格變 更又如專利文獻2之技術般，在未將吸引堆積部區分 為複數個凹部而於底面部上設置有開口面積率（吸引部開 孔面積率）不同之區域之情形時，難以高精度地調整各個 區域之基重。 本發明係關於一種可精度良好地調整吸收體各部分之基 重之吸收體之製造裝置及製造方法。 本發明係一種吸收體之製造裝置，其包含隨著氣流而供

斜下方’沿箭頭R5方向旋轉驅動；真空輸送機6，其配置 於轉移輥5之下方；壓製裝置7;及切斷裝置8。 於製造裝置1中，進而於旋轉筒2之圓周方向上之導管4 與轉移輥5之間配置有真空箱u，以通過真空箱^與旋轉 筒2之間及轉移輥5與旋轉筒2之間之方式配置有網帶Η， 及與轉移輥5之外周面接近而設置有擋風板15。 旋轉筒2如圖1所示形成圓筒狀，接受來自馬達等原動機 之動力而繞水平軸旋轉。如圖3所示，旋轉筒2於其外周面 2!上具有複數個吸引作為吸收體之原料之纖維材料並使其 堆積之吸引堆積部22。旋轉親2之吸引堆積部咖旋轉筒2 之圓周方向（2Χ方向）上以特^之分隔形成有複數個，並且 伴隨旋轉筒2之旋轉而朝圖"2所示之一方向行進。圖3 160798.doc 201231026 中，2X方向為旋轉筒2之圓周方向，2Υ方向為旋轉筒2之 寬度方向（與旋轉筒2之旋轉轴平行之方向）。 如圖2及圖5所示，旋轉筒2包含：圓筒狀之框體25，其 包含金屬製之剛體；多孔性板26’其與框體25之外表面侧 疊合而固定’且包含多孔性材料；及圖案形成板27，其與 多孔性板26之外表面側疊合而固定。多孔性板26及圖案形 成板27係藉由螺栓專周知之固定機構而可裝卸地設置於框 體25上。 框體25具有使梯形物成為環狀而將上下端連結之形狀， 且在與吸引堆積部22對應之各個部位具有貫通内外表面之 連通孔2 5 a。 多孔性板2 6係包含具有多個細孔之多孔性材料且不使隨 著氣流而供給之作為吸收體之原料之纖維材料透過而可僅 使空氣透過者。作為多孔性板26 ’可無特別限制地使用先 前於此種積纖裝置中所使用者，例如，金屬或樹脂製之網 板、或於金屬或樹脂製之板上經蝕刻或穿孔而形成有多個 細孔者等。 圖案形成板27包含：形成旋轉筒2之外周面21之外表面 27a;及朝向旋轉筒2之旋轉軸側之内表面27b。 旋轉筒2之各個吸引堆積部22分別與相當於1片經期衛生 棉或拋棄式尿片等吸收性物品之吸收體3對應。 而且’如圖3所示，各個吸引堆積部22被劃分為於底部 具有包含多孔性材料之吸引部之複數個凹部22 1、222、 223 、 224等。 160798.doc 201231026 若更具體地進行說明’則於吸引堆積部22内，自其行進 方向（R2)之前端側朝後端側依序形成有第1凹部221、第2 凹部222、第3凹部223、第4凹部224及第5凹部225。進 而’於第3凹部223之兩側形成有第6凹部226及第7凹部 227。第1凹部〜第7凹部中整個底部成為包含上述多孔性板 26之吸引部。再者’圖3所示之吸引堆積部22具有相對於 沿行進方向（R2)延伸之縱中央線LX而線對稱之形狀，又具 有相對於沿與該行進方向正交之方向（2γ方向）延伸之橫中 央線LY亦線對稱之形狀。又，本實施形態中使用之多孔 性板2 6中，細孔均勻地分佈於吸引堆積部之整個區域上， 各凹部之吸引部之開孔面積率等為相同。 右以第2凹部222為例對第1凹部221、第2凹部222及第4〜 第7凹部224〜227之形狀進行說明，則如圖3至圖5所示，第 2凹部222具有倒立平截頭稜錐體形狀，於整個區域成為包 含多孔性材料之吸引部222e之底部周圍具有前壁222a、後 壁222b及一對側壁222c、222c。於構成吸引堆積部22之各 凹部221〜227中’前壁係位於吸引堆積部22之行進方向 (R2)之前方的壁面’後壁係位於吸引堆積部22之行進方向 (R2)之後方的壁面’側壁係位於與吸引堆積部22之行進方 向正交之方向之端部的壁面。又’於構成吸引堆積部22之 各凹部221〜227中’前壁、後壁及一對側壁均由非通氣性 材料形成。 而且，第2凹部222中，與朝向供給吸收體原料之侧（導 管側）開口之開口部222d之面積（s 1)相比，包含上述多孔性 160798.doc 201231026 材料之上述吸引部222e之面積（S2)較小。 更具體而言’第2凹部222中，前壁222a及後壁222b分別 如圖4所示傾斜。又，第2凹部222中，一對側壁222c、 222c亦分別如圖5所示傾斜。 於本發明中’所謂前壁或後壁之傾斜係指如圖4所示， 於沿吸引堆積部22之行進方向（R2)之剖面中，凹部之前壁 222a或後壁222b相對於通過該壁之上端且與底部垂直之線 L1以傾斜角度…為5。以上之方式傾斜，所謂側壁之傾斜係 指如圖5所示’在與吸引堆積部22之行進方向（R2)正交之 剖面中’凹部之側壁222c相對於通過該壁之上端且與底部 垂直之線L2以傾斜角度θ2為5。以上之方式傾斜。於旋轉筒 2設置有吸引堆積部之情形時，與上述底部垂直之線[I、 L2係沿旋轉筒2之直徑方向延長之線。 第2凹部222中吸引部之面積si小於開口部222d之面積 S2，由此相較於開口部222d之面積S2與吸引部“。之面積 S1相同之情形，流過該凹部2：22之風量受到抑制。又於 使紙漿纖維等之纖維材料或高吸收性聚合物（SAp)等作為 吸收體原料而堆積於吸引堆積部22之積纖步驟中，纖維材 料/SAP之基重依賴於流過凹部之吸引部的風量。 因此’將吸引堆積部22劃分為複數個凹部，並且將如第 2凹部222般之凹部設置於吸引堆積部22内之使所堆積之吸 收體原料之基重小於其他部位的部位，藉此可以簡易之設 備而精度良好地製造使所需部位之基重降低之吸收體。 又，例如，謀求使構成吸收體之紙漿纖維等之纖維材料 I60798.doc 201231026 /SAP集中於要求較高吸收容量的部分，且使其他部分儘量 低基重化’藉此可獲得吸收性能與降低穿著不適感.不快 感之兩者均優異之吸收體。 又，藉由適當調整開口部222d之面積S2與吸引部222e之 面積si之比率而可容易地使自第2凹部222獲得之堆積物之 平均基重等為所需之值。 尤其是’變更前壁222a及/或後壁222b等之傾斜程度而 調整開口部222d之面積S2與吸引部222e之面積S1之比率， 藉此可變更通過第2凹部222内之風量，且可更容易地使自 第2凹部222獲得之堆積物之平均基重等為所需之值。 又，於加大前壁222a及/或後壁222b之傾斜角度01等或 減少堆積量之情形時’亦容易使該部分之底部維持良好之 通氣性’因此亦可防止於堆積物自各個凹部脫模時之脫模 性之惡化。 上述效果於一對侧壁222c、223c不傾斜之情形時亦奏 效，但於一對側壁222c、223c之一方或雙方傾斜之情形 時，較佳為該側壁之傾斜程度小於前壁222a及後壁222b之 傾斜程度，即，側壁之上述傾斜角度e2(參照圖4)小於前後 壁之上述傾斜角度θ1(參照圖5)。再者，前後壁之傾斜角度 亦可不必相同。 於使凹部之前後及左右之側壁全部傾斜較大之情形時， 各個凹部内會生堆積量之不均。尤其是凹部内之旋轉筒之 旋轉方向（吸引堆積部之行進方向）之前後部的堆積量易變 多，另一方面，凹部内之與該旋轉筒之旋轉方向（吸引堆 160798.doc -9- 201231026 積部之行進方向）正交之方向之兩端部的堆積量易變得不 充分。由於使側壁之上述傾斜角度02小於前後壁之上述傾 斜角度θι，故而可容易地防止凹部内產生堆積不充分之部 位。藉此，作為具有包含堆積於複數個凹部内之複數個堆 積物之集合體之層的吸收體，可獲得使與各凹部對應之堆 積物之形狀具有所需之形狀的吸收體。 再者，第2凹部222之開口部222d係由第2凹部222之前壁 222a、後壁222b及一對側壁222c各自之上緣包圍之部分， 其面積S1係使該開口部222d通過該凹部之底部中央部並投 影至與該底部垂直之方向（旋轉筒2之直徑方向）的面積。另 一方面，第2凹部222之吸引部222e係設置於第2凹部222之 底部之包含多孔性材料的部分，且係由前壁222a、後壁 222b及一對側壁222(：各自之下緣包圍之部分。其面積“係 使該部分通過該凹部之底部中央部並投影至與該底部垂直 之方向（旋轉筒2之直徑方向）的面積。再者，開口部與吸引 部及其面積之定義對於吸引堆積部22之其他凹部亦為相 同。例如，於圖4、圖6、圖7中，以符號22Id及221 e表示 第1凹部221之開口部及吸引部，以符號223d& 223e表示第 3凹部223之開口部及吸引部，以226d及吸引部226e表示第 6凹部226之開口部及吸引部，以符號227d& 227e表示第7 凹部227之開口部及吸引部。 前壁及/或後壁之傾斜角度Θ1(參照圖4)較佳為5。〜85。， 更佳為10。〜45。，進而佳為15。〜30。。 另一方面，於使側壁222c、222c傾斜之情形時，該傾斜 160798.doc 201231026 之側壁222c之傾斜角度θ2(參照圖5)較佳為前壁。以及/或 後壁222b之傾斜角度01之1〇〜9〇%，更佳為5〇〜8〇%。又， 傾斜之側壁222c之傾斜角度θ2例如可為丨。〜6〇。，更佳為 5。〜15。。 又，第2凹部222之底部之吸引部222e之面積S2較佳為第 2凹部222之開口部222d之面積S1的20%〜80%，更佳為 30%〜60%。又，前壁222a及/或後壁222b傾斜之第2凹部 222中’沿吸引堆積部22之行進方向之方向的開口部222d 之尺寸L3與底部吸引部222e之尺寸L4之比（L3/L4)較佳為 1·1〜2.0，更佳為1.3〜1.7。 又’鄰接之凹部間被分隔構件28Α隔開。分隔構件28Α 之寬度（與該分隔構件28Α延伸之方向正交之方向之尺寸） 於其上端部成為最小，其最小之寬度較佳為1 〇 mm以下， 更佳為0.5〜5.0 mm。 本實施形態中之第2凹部222於2Y方向上形成有複數個相 同形狀者。又’第4凹部224具有與第2凹部222相同之形 狀。又，第1凹部221及第5凹部225中除前壁或後壁於俯視 時形成為圓弧狀以外，具有與第2凹部222相同之形狀。 又，第6凹部226中，與行進方向（R2)正交之方向之尺寸較 小而為第2凹部222之一半左右，除此以外具有與第2凹部 222相同之形狀。如圖3及圖6所示，第6凹部226形成為沿 吸引堆積部22之寬度方向（2Y方向）之兩端緣分別串聯有複 數個。又，第7凹部227形成為於第3凹部223及第6凹部226 之間串聯有複數個。對第7凹部227而言，第3凹部223側之 160798.doc -11 · 201231026 側壁於俯視時形成為圓弧狀’並且與行進方向（R2)正交之 方向之尺寸形成為小於第2凹部222，除此以外具有與第2 凹部222相同之形狀。 第1凹部221、第4凹部224、第5凹部225、第6凹部226及 第7凹部2 2 7之前後壁或側壁之傾斜角度、開口部之面積與 底部吸引部之面積比等與第2凹部222為相同，適當使用關 於第2凹部之說明。 又’第6凹部226之前後壁226a、226b之傾斜角度較佳為 小於存在於靠近吸引堆積部22之前端或後端之第2及第4凹 部等之前後壁的傾斜角度。同樣地，第7凹部227之前後壁 之傾斜角度較佳為小於存在於靠近吸引堆積部22之前端或 後端之第2及第4凹部等之前後壁的傾斜角度。 關於本實施形態中之第3凹部223，其兩側壁形成為俯視 圓弧狀’且以隨著自中央朝向吸引堆積部22之前端及後端 而使2Y方向之寬度變窄的方式形成。前壁及後壁形成為俯 視直線狀。第3凹部223之前後壁及側壁之任一者均未傾

吸引部為止的深度彼此相等。 160798.doc •12· 201231026 於本實施形態之吸引堆積部22中，配置有上述第3凹部 223之區域係使吸收體原料堆積成高基重之高基重堆積區 域，配置有上述第1凹部221、第2凹部222及第4〜第7凹部 224〜227之區域係使吸收體原料堆積成基重低於上述高基 重堆積區域之低基重堆積區域。 堆積於各凹部之吸收體原料之基重係將堆積於各凹部内 之吸收體原料之質量除以各凹部之開口部之面積而計算 出。 又，於本實施形態之各個吸引堆積部22中，劃分形成有 複數個凹部221〜227。藉此，成為各凹部難以受到來自其 他凹部之影響之構造，根據本實施形態之吸收體之製造裝 置，可於各凹部内使吸收體原料之基重精度良好地堆積。 進而’於本實施形態之各個吸引堆積部22中，凹部 221〜227在吸引堆積部22之行進方向及與該行進方向正交 之方向上分別形成有複數個，故而亦可於通常難以堆積之 寬度方向及長度方向上使吸收體原料之基重精度良好地堆 積。 本實施形態中，將凹部間隔開之分隔構件28A構成圖案 形成板27之一部分。更具體而言，以與合成樹脂製之圖案 形成板27之内表面27b形成同一平面之方式，一體形成將 凹部間隔開之分隔構件28 A。再者，亦可將與圖案形成板 27分開之分隔構件28A直接固定設置於多孔性板26上。 於旋轉筒2之内侧（旋轉轴側），如圖1所示形成有相互間 被隔開之空間B、C及D。於空間B中，連接有進氣扇等周 160798.doc -13- 201231026 . 知之排氣裝置（未圖示）’藉由使該排氣裝置作動而可將該 空間B内維持於負M。於空間c中，藉由來自下述真空箱 11側之吸引而流入有外部之空氣，於空間D中，藉由來自 轉移輥5側之吸引而流入有外部之空氣。為了良好地進行

真空輸送機6包含：架設於驅動輥61及從動輥62、62上 之環狀之通氣性傳送帶63 ;及夾持通氣性傳送帶63而配置 於與轉移報5對向之位置之真空箱64。 真空箱11具有包含上下表面、左右之兩側面及背面之箱 狀的形狀，且包含朝向旋轉筒2方向開口之開口部。真空 箱Π經由未圖示之排氣管等而連接有進氣扇等周知之排氣 裝置（未圖示）’並藉由該排氣裝置之作動而可將真空箱U

一對’防止或減輕來自側方之風之流入，從而防止自吸引 堆積部22脫模之堆積物32之配置或形狀變形等。尤其可藉 由與轉移輥5接近設置之擒風板9、9而防止或減輕自輥5之 寬度方向之左右外方朝該輥之具有吸引孔之區域流入風， 故而可有效地防止靠近輥之寬度方向兩端之堆積物倒向靠 近中央之堆積物，或堆積物相互間之配置產生錯亂等之不 良情形。擋風板15之材質並無特別限制，但自具有可抵抗 風之剛性之觀點而言，較佳為金屬或合成樹脂製，且具有 0.5〜10mm左右之厚度。 壓製裝置7包含表面平滑之一對輥71、72，且對導入至 輥71、72間之被加壓物自上下表面進行加壓而沿厚度方向 可壓縮地構成。作為壓製裝置7,代替包含表面平滑之一 對輥71、72者而使用包含於一方或雙方之輥之周面上形成 有壓紋用之凸部之一對壓紋輥者，自可於吸收體上形成由

體3之方法、即本發明之吸收體之製造方法之一實施態樣 進行說明。 為使用吸收體之製造裝置1製造吸收體3，使連接於旋轉 筒2内之空間B、轉移輥5内之空間E、及真空箱丨丨之排氣裝 置作動而使該些部分成為負壓。由於使空間B内為負壓， 因此於導管4内產生將吸收體之原料搬送至旋轉筒2之外周 面之氣流。又，使旋轉筒2及轉移輥5旋轉，並使真空輸送 機6作動》 然後’若使纖維材料導入裝置作動而向導管4内供給纖 維材料，則該纖維材料會隨著流過導管4内之氣流而成飛 散狀態並朝旋轉筒2之外周面供給。 於搬送被導管4覆蓋之部分之期間，於旋轉筒2之吸引堆 積部22之第1〜第7凹部221〜227内吸引並堆積有纖維材料 3 1。圖8表示通過導管4之下游側端部4丨之時間點之吸引堆 積部内之各凹部的剖面。 本實施態樣中，如圖8所示，堆積於第2凹部222内之堆 積物32於俯視時之面積與第2凹部222之開口部222d之面積

In addition, it is necessary to perform a large-scale operation such as changing the arrangement of the partition walls of the suction chamber in the rotary cylinder, and it is not possible to flexibly cope with the specification change of the absorbent body. As in the technique of Patent Document 2, the suction accumulation portion is not divided into plural numbers. When the recessed portion is provided with a region having a different opening area ratio (opening area ratio of the suction portion) on the bottom surface portion, it is difficult to adjust the basis weight of each region with high precision. The present invention relates to a manufacturing apparatus and a manufacturing method of an absorbent body which can accurately adjust the basis weight of each part of the absorbent body. The present invention relates to an apparatus for producing an absorbent body, comprising: a conduit for supplying an absorbent body material with a gas flow; and a suction deposition portion that sucks and accumulates the absorbent material supplied from the conduit, and the suction deposition portion faces the first The deposition material is deposited in the suction deposition portion after the direction is advanced, and the deposit is released from the suction deposition portion.

Doc 201231026 Further, the present invention provides a method for producing an absorbent body which is produced by using the above-described apparatus for producing an absorbent body, and which is manufactured as follows. a deposit having a high basis weight which is demolded from the above-mentioned concave portion of the above-described high basis weight accumulation region; & a deposit having a low basis weight which is demolded from the concave portion above the low basis weight accumulation region. [Embodiment] Hereinafter, the present invention will be described with reference to the preferred embodiments. Fig. 1 shows an embodiment of a manufacturing apparatus of an absorbent body of the present invention. The manufacturing apparatus 1 of the absorbent body shown in Fig. 1 includes a rotary cylinder 2 which is driven in the direction of an arrow R2, and a duct 4 which supplies a fiber material as a raw material of the absorbent body to the outer peripheral surface of the rotary cylinder 2; 5, which is disposed under the oblique direction of the rotating cylinder 2 'rotually driven in the direction of the arrow R5; the vacuum conveyor 6, which is disposed below the transfer roller 5; the pressing device 7; and the cutting device 8. In the manufacturing apparatus 1, a vacuum box u is further disposed between the duct 4 and the transfer roller 5 in the circumferential direction of the rotary cylinder 2 to pass between the vacuum chamber 2 and the rotary cylinder 2, and between the transfer roller 5 and the rotary cylinder 2 A mesh belt 配置 is disposed between the two, and a windshield 15 is disposed adjacent to the outer peripheral surface of the transfer roller 5. The rotary cylinder 2 is formed in a cylindrical shape as shown in Fig. 1, and is rotated about a horizontal axis by receiving power from a prime mover such as a motor. As shown in Fig. 3, the rotary cylinder 2 has a plurality of suction stacking portions 22 on the outer peripheral surface 2! of which a plurality of fibrous materials which are the raw materials of the absorbent body are attracted and stacked. In the circumferential direction (2 Χ direction) of the rotation stacking unit 2 of the rotating parent 2, a plurality of pieces are formed in a plurality of divisions, and the rotation of the rotating cylinder 2 proceeds in one direction shown in Fig. 2 . Figure 3 160798. In doc 201231026, the 2X direction is the circumferential direction of the rotating drum 2, and the 2Υ direction is the width direction of the rotating drum 2 (the direction parallel to the rotating shaft of the rotating drum 2). As shown in FIGS. 2 and 5, the rotary cylinder 2 includes a cylindrical frame 25 including a rigid body made of metal, and a porous plate 26' which is superposed on the outer surface side of the frame 25 to be fixed and includes A porous material; and a pattern forming plate 27 which is superposed on the outer surface side of the porous plate 26 and fixed. The porous plate 26 and the pattern forming plate 27 are detachably provided to the casing 25 by a fixing mechanism known as a bolt. The frame body 25 has a shape in which the trapezoidal shape is formed in a ring shape and connects the upper and lower ends, and each of the portions corresponding to the suction and accumulation portion 22 has a communication hole 25a that penetrates the inner and outer surfaces. The porous sheet 26 includes a porous material having a plurality of pores and does not allow the fiber material as a raw material of the absorbent body to be supplied with the gas flow to pass through only the air. The porous plate 26' can be formed without any particular limitation by using a user previously used in such a fiber-splitting device, for example, a metal or resin mesh plate, or a metal or resin plate which is etched or perforated. A number of fine holes, etc. The pattern forming plate 27 includes an outer surface 27a that forms the outer peripheral surface 21 of the rotating cylinder 2, and an inner surface 27b that faces the rotating shaft side of the rotating cylinder 2. Each of the suction stacking portions 22 of the spin basket 2 corresponds to an absorber 3 corresponding to an absorbent article such as one menstrual sanitary napkin or disposable diaper. Further, as shown in Fig. 3, each of the suction accumulation portions 22 is divided into a plurality of concave portions 22 1 , 222 , 223 , 224 and the like having a suction portion including a porous material at the bottom portion. 160798. Doc 201231026, in more detail, in the suction stacking portion 22, the first recessed portion 221, the second recessed portion 222, and the third recessed portion 223 are sequentially formed from the end side toward the rear end side in the traveling direction (R2). The fourth recess 224 and the fifth recess 225. Further, a sixth concave portion 226 and a seventh concave portion 227 are formed on both sides of the third concave portion 223. The entire bottom portion of the first recessed portion to the seventh recessed portion serves as a suction portion including the porous plate 26. Further, the attraction stacking portion 22 shown in FIG. 3 has a line symmetrical shape with respect to the longitudinal center line LX extending in the traveling direction (R2), and has a direction orthogonal to the traveling direction (2 γ direction). The extended transverse center line LY is also in the shape of a line symmetry. Further, in the porous sheet 26 used in the present embodiment, the pores are uniformly distributed over the entire region of the suction deposition portion, and the opening area ratios of the suction portions of the respective concave portions are the same. The shape of the first recess 221, the second recess 222, and the fourth to seventh recesses 224 to 227 will be described by taking the second recess 222 as an example. As shown in FIGS. 3 to 5, the second recess 222 has an inverted flat. The truncated pyramid shape has a front wall 222a, a rear wall 222b, and a pair of side walls 222c and 222c around the bottom of the suction portion 222e including the porous material. Among the recesses 221 to 227 constituting the suction stacking portion 22, the wall surface 'below the front wall in the traveling direction (R2) of the suction stacking portion 22 is located behind the traveling direction (R2) of the suction stacking portion 22. The wall surface side wall is located on the wall surface at the end portion in the direction orthogonal to the traveling direction of the suction stacking portion 22. Further, the front wall, the rear wall, and the pair of side walls are formed of a non-air permeable material in each of the concave portions 221 to 227 constituting the suction stacking portion 22. Further, the second recessed portion 222 includes the above-described porosity 160798 as compared with the area (s 1) of the opening portion 222d that opens toward the side (the tube side) where the absorbent material is supplied. Doc 201231026 The area (S2) of the above-mentioned attraction portion 222e of the material is small. More specifically, in the second recess 222, the front wall 222a and the rear wall 222b are inclined as shown in Fig. 4, respectively. Further, in the second recess 222, the pair of side walls 222c and 222c are also inclined as shown in Fig. 5, respectively. In the present invention, the term "the inclination of the front wall or the rear wall" means that, as shown in FIG. 4, in the section along the traveling direction (R2) of the suction stacking portion 22, the front wall 222a or the rear wall 222b of the recess is opposed to the wall. The line L1 at the upper end and perpendicular to the bottom is at an inclination angle of .... In the above manner, the inclination of the side wall means that the side wall 222c of the recess portion is perpendicular to the upper end of the wall and perpendicular to the bottom portion in the cross section orthogonal to the traveling direction (R2) of the attraction stacking portion 22 as shown in FIG. The line L2 has an inclination angle θ2 of 5. The above method is tilted. When the rotating cylinder 2 is provided with the suction stacking portion, the line [I, L2) perpendicular to the bottom portion is extended along the diameter direction of the rotating cylinder 2. The area si of the suction portion in the second recess 222 is smaller than the area S2 of the opening 222d, and the airflow flowing through the recess 2:22 is the same as the area S2 of the opening 222d and the area S1 of the suction portion. In addition, the fiber material such as pulp fibers or a superabsorbent polymer (SAp) is deposited as a raw material of the absorbent body in the fiber-forming step of the suction deposition portion 22, and the basis weight of the fiber material/SAP depends on the flow. Therefore, the air volume of the suction portion of the concave portion is divided into a plurality of concave portions, and the concave portion such as the second concave portion 222 is disposed in the suction deposition portion 22 so that the basis weight of the absorbent material deposited is smaller than the other In the position of the part, the absorbent body which reduces the basis weight of the desired part can be manufactured with a simple and simple apparatus. Further, for example, the fiber material I60798 which is a pulp fiber constituting the absorbent body is obtained. Doc 201231026 /SAP focuses on the part that requires higher absorption capacity, and makes other parts as low as possible to base on 'by taking absorption performance and reducing wearing discomfort. An unpleasant absorber that is both excellent. Further, by appropriately adjusting the ratio of the area S2 of the opening portion 222d to the area si of the suction portion 222e, the average basis weight of the deposit obtained from the second concave portion 222 can be easily made to a desired value. In particular, the ratio of the area S2 of the opening 222d and the area S1 of the suction portion 222e can be changed by changing the inclination of the front wall 222a and/or the rear wall 222b, etc., whereby the amount of air passing through the second recess 222 can be changed, and It is easier to make the average basis weight of the deposit obtained from the second concave portion 222 equal to a desired value. Further, when the inclination angle 01 of the front wall 222a and/or the rear wall 222b is increased or the amount of deposition is reduced, it is also easy to maintain a good air permeability at the bottom of the portion, thereby preventing deposits from being formed in the respective recesses. The mold release property at the time of demolding is deteriorated. The above effect is also effective when the pair of side walls 222c, 223c are not inclined. However, when one or both of the pair of side walls 222c, 223c are inclined, it is preferable that the side wall is inclined less than the front wall 222a and the rear wall. The degree of inclination of 222b, that is, the above-described inclination angle e2 (see FIG. 4) of the side wall is smaller than the above-described inclination angle θ1 of the front and rear walls (refer to FIG. 5). Furthermore, the inclination angles of the front and rear walls may not necessarily be the same. When the front and rear sides of the recessed portion and the left and right side walls are all inclined large, unevenness of the amount of accumulation occurs in each of the recessed portions. In particular, the amount of accumulation in the rear portion of the rotating cylinder in the concave portion (the direction of travel of the suction stacking portion) tends to increase, and on the other hand, the direction of rotation of the rotating cylinder in the recess portion (attraction stack 160798. Doc -9- 201231026 Direction of travel of the product) The amount of accumulation at both ends of the orthogonal direction is likely to be insufficient. Since the inclination angle 02 of the side wall is made smaller than the above-described inclination angle θι of the front and rear walls, it is possible to easily prevent the occurrence of insufficient accumulation in the concave portion. As a result, as an absorber having a layer including an aggregate of a plurality of stacked materials stacked in a plurality of concave portions, an absorbent body having a desired shape of the stacked material corresponding to each concave portion can be obtained. Further, the opening 222d of the second recess 222 is a portion surrounded by the upper edges of the front wall 222a, the rear wall 222b, and the pair of side walls 222c of the second recess 222, and the area S1 is such that the opening 222d passes through the recess. The central portion of the bottom portion is projected to an area perpendicular to the bottom (the diameter direction of the rotating cylinder 2). On the other hand, the suction portion 222e of the second concave portion 222 is provided at a portion including the porous material at the bottom of the second concave portion 222, and is composed of a front wall 222a, a rear wall 222b, and a pair of side walls 222 (the respective lower edges) a portion surrounded by "the area is such that the portion passes through the central portion of the bottom portion of the recess and is projected to an area perpendicular to the bottom (the diameter direction of the rotating cylinder 2). Further, the opening portion and the suction portion and the area thereof The definition is the same for the other concave portions of the suction stacking portion 22. For example, in Figs. 4, 6, and 7, the opening portions and the suction portions of the first concave portion 221 are indicated by reference numerals 22Id and 221 e, and are indicated by symbols 223d & 223e.

Further, the inclination angle θ2 of the inclined side wall 222c may be, for example, 丨. ~6〇. More preferably 5. ~15. . Further, the area S2 of the suction portion 222e at the bottom of the second concave portion 222 is preferably 20% to 80%, more preferably 30% to 60%, of the area S1 of the opening portion 222d of the second concave portion 222. Further, in the second concave portion 222 in which the front wall 222a and/or the rear wall 222b are inclined, the ratio of the dimension L3 of the opening 222d in the direction in which the suction stacking portion 22 travels to the dimension L4 of the bottom suction portion 222e (L3/L4) ) preferably from 1·1 to 2. 0, more preferably 1. 3~1. 7. Further, the adjacent recesses are separated by a partition member 28Α.

In the second embodiment, the second concave portion 222 is formed in a plurality of identical shapes in the 2Y direction. Further, the fourth recess 224 has the same shape as the second recess 222. Further, the first concave portion 221 and the fifth concave portion 225 have the same shape as the second concave portion 222 except that the front wall or the rear wall is formed in an arc shape in plan view. Further, in the sixth recessed portion 226, the dimension in the direction orthogonal to the advancing direction (R2) is smaller than one half of the second recessed portion 222, and has the same shape as the second recessed portion 222. As shown in Fig. 3 and Fig. 6, the sixth recessed portion 226 is formed by connecting a plurality of end edges in the width direction (2Y direction) of the suction stacking portion 22 in series. Further, the seventh recessed portion 227 is formed in series between the third recessed portion 223 and the sixth recessed portion 226. For the seventh recess 227, the third recess 223 side is 160798. Doc -11 · 201231026 The side wall is formed in an arc shape in a plan view and is smaller in the direction orthogonal to the traveling direction (R2) than the second recess 222, and has the same shape as the second recess 222.

Doc • 12·201231026 In the suction deposition unit 22 of the present embodiment, the region in which the third concave portion 223 is disposed is a high-basis accumulation region in which the absorbent material is deposited to a high basis weight, and the first concave portion 221 is disposed. The regions of the second concave portion 222 and the fourth to seventh concave portions 224 to 227 are such that the absorbent body material is deposited in a low basis weight accumulation region having a basis weight lower than the high basis weight accumulation region. The basis weight of the absorbent material deposited in each of the concave portions is calculated by dividing the mass of the absorbent material deposited in each concave portion by the area of the opening of each concave portion. Further, in each of the suction deposition portions 22 of the present embodiment, a plurality of concave portions 221 to 227 are formed. As a result, the recessed portions are less likely to be affected by the other recessed portions.

As shown in Fig. 1, the duct 4 has a one end side covering the outer peripheral surface of the rotary cylinder 2 located in the space B, and has a fiber material introduction device on the other end side (not shown). The fiber material introduction device has, for example, a pulverizer which pulverizes the sheet-like wood pulp to prepare a defibrated pulp, and feeds the defibrated pulp (fiber material) into the catheter. A water-absorptive polymer introduction portion into which particles of the water-absorptive polymer are introduced may be provided in the middle of the catheter 4. Each of the suction stacking portions 22 of the rotary cylinder 2 is sucked by the suction portions of the first to seventh concave portions 221 to 227 including the porous material while being held in the space B of the negative pressure. The raw material of the absorber introduced from the fiber material introduction portion or the water-absorptive polymer introduction portion is transported to the rotary cylinder 2 in the duct 4 by the suction "from the pores of the suction portion of the concave portion including the porous material". The airflow of the outer peripheral surface and the raw material conveyed along with the airflow are deposited in the concave portions 221 to 227 of the suction deposition portion 22. The transfer roller 5 includes a cylindrical outer peripheral portion having aeration, and is received from 160798. Doc 201231026 The motive of a motor such as a motor rotates its outer circumference around a horizontal axis. A non-rotating portion on the inner side (rotational axis side) of the transfer roller 5 is formed with a space E ^ for decompressing the inside, and a well-known exhaust device (not shown) such as an intake fan is connected to the space E. The exhaust device is actuated to maintain the interior of the space E at a negative pressure. On the outer peripheral surface 51 of the transfer roller 5, a plurality of suction holes communicating the inside and the outside are formed. The suction holes suck the air into the inside from the outside while being maintained in the space E of the negative pressure, and the deposit 32 in the suction stacking portion 22 is smoothly transferred from the rotating drum 2 by the suction force. Onto the transfer roller 5. The vacuum conveyor 6 includes an annular ventilating belt 63 that is stretched over the driving roller 61 and the driven rollers 62 and 62, and a vacuum box 64 that is placed at a position opposed to the shifting sheet 5 by sandwiching the ventilating belt 63. . The vacuum box 11 has a box shape including upper and lower surfaces, right and left side surfaces, and a back surface, and includes an opening that opens in the direction of the rotating cylinder 2. In the vacuum box, a well-known exhaust device (not shown) such as an intake fan is connected via an exhaust pipe (not shown) or the like, and the inside of the vacuum box U can be maintained at a negative pressure by the operation of the exhaust device. . The mesh belt 13 is formed by connecting a belt-shaped air-permeable belt having a mesh shape in a ring shape, and is guided by a plurality of free rollers 14 and a transfer newspaper 5 to continuously move on a specific path. The mesh belt 13 is driven by the rotation of the transfer roller 5. As shown in FIG. 1, the mesh belt 13 is disposed in such a manner as to be sequentially passed between the vacuum box 11 and the rotary cylinder 2 after being introduced into the outer peripheral surface of the rotary cylinder 2 near the downstream end portion 41 of the duct 4. Transfer between the parent 5 and the rotating cylinder 2. The mesh belt 13 is in contact with the outer peripheral surface of the red drum 2 while passing through the opening portion of the vacuum box u. The closest to the transfer roller 5 and the rotating cylinder 2 is 160798. Near the portion of the doc 15 201231026, it is separated from the outer peripheral surface of the rotating cylinder 2 and transferred to the transfer roller 5. The mesh belt 13 has pores smaller than the suction holes of the transfer roller 5, and suction from the suction holes of the transfer roller 5 also attracts the fine holes from the mesh belt 13 overlapped with the suction holes. The windshield 15 sandwiches a region in which the suction hole is formed in the width direction of the outer circumferential surface of the transfer roller, and a pair of 'two sides' are provided on both sides to prevent or reduce the inflow of the wind from the side, thereby preventing the self-attracting portion. 22 The configuration or shape deformation of the demolded deposit 32, and the like. In particular, it is possible to prevent or reduce the inflow of air from the left and right outer sides of the width direction of the roller 5 toward the region having the suction hole of the roller by the hurricane plates 9 and 9 disposed adjacent to the transfer roller 5, so that the proximity roller can be effectively prevented. The deposits at both ends in the width direction are reversed to the deposit near the center, or the arrangement of the deposits is disordered. The material of the windshield 15 is not particularly limited, but is preferably made of metal or synthetic resin and has a refractive index of 0. A thickness of about 5 to 10 mm. The pressing device 7 includes a pair of rolls 71 and 72 having a smooth surface, and pressurizes the object to be pressed introduced between the rolls 71 and 72 from the upper and lower surfaces to be compressible in the thickness direction. As the pressing device 7, instead of including the surface smoothing pair of rolls 71 and 72, one of the convex portions for embossing formed on one or both of the rolls is applied to the embossing roll, and the embossing roll can be absorbed. It is also preferable to form a low-density portion and a high-density portion which are realized by embossing to improve the absorption performance. X, a belt type pressing device or the like may be used instead of a roller. As the cutting device 8, in the manufacture of menstrual sanitary napkins or absorbent articles, the former cutters for the continuum of the absorbent body can be used with particular limitation. Doc 201231026 and so on. The cutting device 8 shown in Fig. 1 includes a cutting roller 82 having a cutting edge 8i on its circumferential surface, and an anvil roller 83 which is smooth in the circumferential surface of the cutting blade. Next, a method of continuously manufacturing the absorbent body 3 using the above-described absorbent body manufacturing apparatus 1, that is, an embodiment of the production method of the absorbent body of the present invention will be described. The absorbent body 3 is manufactured for the manufacturing apparatus 1 using the absorbent body, and the space B connected to the inside of the rotating cylinder 2, the space E in the transfer roller 5, and the exhaust device of the vacuum box 作 are actuated to make the portions become negative pressure. . Since the inside of the space B is made to have a negative pressure, a flow of the raw material of the absorbent body to the outer surface of the rotary cylinder 2 is generated in the duct 4. Further, the rotary drum 2 and the transfer roller 5 are rotated, and the vacuum conveyor 6 is actuated. Then, if the fiber material is supplied into the conduit 4 by the operation of the fiber material introduction device, the fiber material flows through the conduit 4. The airflow is in a scattered state and supplied to the outer peripheral surface of the rotary cylinder 2. While the portion covered by the duct 4 is being conveyed, the fiber material 3 1 is sucked and deposited in the first to seventh recesses 221 to 227 of the suction stacking portion 22 of the rotary drum 2. Fig. 8 shows a cross section of each concave portion in the suction stacking portion passing through the downstream end portion 4 of the duct 4. In the present embodiment, as shown in FIG. 8, the area of the deposit 32 deposited in the second recess 222 is substantially the same as the area of the opening 222d of the second recess 222, but the front and rear walls 222a, 222b Since the amount of the fiber material as the raw material of the absorber is the same as that of the opening 222d, the wall and the side wall are not inclined. The reason for this is that the second recess 222 is attracted by the inclination of the second recess 222 before the rear walls 222a, 222b, etc. I60798. Doc -17· 201231026 The area of the lead portion 222e is reduced, and as a result, the amount of air passing through the second recess 222 is reduced as compared with the case where the front wall and the side wall are not inclined. Further, after the excessive amount of the fibrous material exceeding the position of the outer peripheral surface 21 is deposited in each of the concave portions, the excessive amount of the iron-dimensional material may be removed by a raising roller or the like. In this manner, the fibrous material is deposited in the respective concave portions 221 to 227 in the suction stacking portion 22, and then the rotary cylinder 2 is further rotated. Then, when the suction stacking portion 22 reaches the opposing position of the vacuum box 11, the deposit 32 accumulated in each of the recessed portions 221 to 227 of the suction stacking portion 22 is adsorbed to the mesh belt 13 by suction from the vacuum box 11. In the state above, it is transported to the closest portion of the transfer parent 5 and the rotation 2 or its vicinity. Then, it is transferred to the transfer roller $ together with the mesh belt 13 by suction from the transfer roller 5 side, and is also released from the recesses 221 to 227. As in the present embodiment, the deposit 32 is self-rotating. Before the recesses 221 to 227 of the cylinder 2 are released from the mold, the deposit 32 is sucked while being sucked from the side opposite to the rotary cylinder 2 by the vacuum box 11, and then released from the recess 22, and the deposit is deposited. When transferring to the transfer roller 5 or other transfer mechanism, it is possible to effectively prevent the shape of the deposit from being deformed or the arrangement of the deposits from being disturbed. The deposit 32 transferred to the transfer roller 5 is conveyed while being sucked from the side of the transfer roller 5 and delivered to the vacuum conveyor 6. In the present embodiment, as shown in FIG. 1, a core coated sheet 37 including a toilet paper or a liquid permeable nonwoven fabric is introduced onto the vacuum conveyor 6 before the deposit 32 is placed, and the core coated sheet is coated on the core. A deposit 32 is transferred onto the sheet 37. Then, downstream of it, the two sides of the core-coated sheet 37 are folded back, including a complex 160798. Doc -18· 201231026 The upper and lower faces of the absorber 3 of the aggregate of the plurality of deposits 32 are covered by the core wrap sheet 37. Then, the absorbent body 3 in a state in which the core-coated sheet 37 is covered is introduced between the pair of rolls 71, 72 of the pressing device 7 and compressed in the thickness direction. As shown in FIG. 9, the absorber 3 obtained in the present embodiment includes a deposit 221' which is released from the i-th recess 221, a deposit 222' which is released from the second recess 222, and a strip 223' which is released from the third recess 223.

Moreover, compared with the deposits 22A, 222', 224, 225', 226, and 227' which are released from the first recessed portion, the second recessed portion, and the fourth to seventh recessed portions of the low basis weight region, The deposit 223 disposed in the third recessed portion of the south base heavy accumulation region is a high base, and the deposit 221 is released from each of the first recess, the second recess, and the fourth recess to the seventh recess. 222, 224, 225, 226, and 227' have front and rear portions 'in the direction corresponding to the direction in which the suction stacking portion 22 travels (the direction in the direction of FIG. 3), and have absorbent body materials stacked in the vicinity of the front and rear walls. The low basis weight portion has a high basis weight portion including the absorbent body material deposited on the respective suction portions at the respective center portions. Further, from the i-th recess and the second recess. p, the deposits 221, 222, 224 225, 226, 227 of the recesses of the fourth recess to the seventh recess are two in the direction orthogonal to the traveling direction of the suction stacking portion 22 The end portion also has a low basis weight having a basis weight lower than the above-described high basis weight portion. 160798. Doc 201231026 Further, the thickness of the deposits 22Γ-227' which are released from the recesses of the first recessed portion to the seventh recessed portion is substantially the same. As shown in Fig. 9, in the manufacturing apparatus and manufacturing method of the absorbent body of the present invention, the plurality of deposits 221 to 227 of the absorption system which are released from the suction stacking portion 22, the aggregates of which can be not subjected to the pressing device 7 The person who is pressurized may be coated with the anger cover sheet 37 without being pressed by the pressing device 7 or the like. In the present embodiment, the absorber 3 including the plurality of deposits 221· to 227' is actively reduced by the pressing device 7 and pressurized from the first! The thickness of the deposits 22Γ to 227 after the recesses of the recessed portion to the seventh recessed portion are demolded. Thereby, the absorbent body 3B having a small difference in thickness as shown in Fig. 10 was obtained. The absorber 3B includes a compressed material 221 "~227" which is obtained by compressing the deposits 221' to 2 2 7 which are released from the first to seventh recesses in the thickness direction, and is self-disposed in the low basis weight region. The first concave portion, the second concave portion, and the fourth to seventh concave portion demolded deposits 221, 222, 224', 225', 226', and 22'' are disposed in the high basis weight accumulation region. The recessed deposit 223' of the recess is a high basis weight. Further, the compressed bodies 221", 222", 224", 225Μ, 226", 227" of the deposits which are released from the recesses of the first recessed portion, the second recessed portion, and the fourth recessed portion to the sixth recessed portion all contain the compressed material The compressed material has a low-density portion L including the absorbent material deposited in the vicinity of the front and rear walls in the rear portion in the direction corresponding to the traveling direction of the suction stacking portion 22 (the 3X direction in the drawing), and is located at the center in the same direction. The portion has a high-density portion including an absorbent material which is deposited on the bottom of the porous material and which is formed on each of the recesses.

According to the manufacturing apparatus and manufacturing method of the absorbent body of the present embodiment, The shape or arrangement of the concave portion formed in the suction deposition portion can be changed by the replacement of the pattern forming plate or the like, thereby flexibly coping with the specification change of the shape of the absorbent body, etc. Further, the apparatus for manufacturing an absorbent body according to the present embodiment and In the production method, in the suction deposition portion, a portion where the absorbent material is to be deposited to a high basis weight is set as a high basis weight accumulation region, and the absorbent material is to be deposited to have a basis weight lower than that of the high basis weight pile. The portion of the basis weight is set to a low basis weight accumulation region, and the ratio of the area of the suction portion disposed in the concave portion of the low basis weight accumulation region to the area of the opening portion is smaller than the suction portion of the concave portion located in the high basis weight accumulation region.

Interesting deposited 160,798 in the absorbent body raw materials. Doc -21 - 201231026 In the step, since the absorbent material is supplied to the suction deposition portion in the conduit in a state of being mixed with air, the basis weight of the absorbent material deposited in the suction deposition portion depends on the amount of air passing through the suction deposition portion. That is, the concave portion located in the low-basis accumulation region in the suction accumulation portion is smaller than the concave portion located in the high-basis weight accumulation region, and thus the low-weight accumulation region is compared with the high basis weight accumulation region. The absorbent material is deposited to a low basis weight. Moreover, since the air volume in the south base heavy accumulation area and the low base weight accumulation area is different through the concave portion, the wind pressure applied to the concave portion in the concave portion of the low base weight accumulation area is larger than the concave portion located in the high base weight accumulation area. Go low. Thereby, as shown in Fig. 8(a), the absorbent material deposited in the concave portion 222 of the low basis weight accumulation region is piled up as compared with the absorbent material deposited in the concave portion 223 of the high basis weight accumulation region. Low density. Therefore, according to the apparatus and the manufacturing method of the absorbent body of the present embodiment, the basis weight of the desired portion of the absorbent body can be easily and accurately reduced. In particular, it is difficult to cause insufficient accumulation in the concave portion by making the front wall and/or the rear wall of the concave portion located in the low basis weight accumulation region more inclined than the front wall and/or the rear wall of the concave portion located in the high base weight accumulation region. Therefore, the basis weight of the absorbent body material can be further adjusted with high precision. Further, by making the inclination angle Θ2 of the side wall smaller than the inclination angle Θ1 of the front and rear walls, it is possible to further prevent a portion where the accumulation is insufficient in the concave portion, so that the basis weight of the absorbent body material can be further accurately adjusted and stabilized. An absorbent body in which a deposit of a desired shape is disposed in a desired state is efficiently produced. Further, in this manner, the front wall, the rear wall, and the pair of side walls are inclined. Therefore, the mold release property of the deposit can be improved by the low basis weight which is easy to reduce the mold release property of the deposit. 160798.

Further, a low-loss portion and a high-density portion can be formed in the compressed material of the deposit which is released from the concave portion. Forming a low basis weight portion and a high basis weight portion having a different basis weight in all or a part of the deposit, in particular, forming a low basis weight portion before or around the high basis weight portion has, for example, a softness and a feeling of wearing. Absorber and other advantages. A low-density portion and a high-density portion having different densities are formed in the compressed material of all or a part of the deposit, and a low-density portion is formed in front of or around the high-density portion, for example, by rapidly passing body fluid through the low-density portion. Absorbing and fixing body fluids in high-density parts can improve the absorption properties of the compacts of the deposits themselves.
