従来より、紙おむつ、ナプキン等に使用される吸収体を連続的に製造する装置としてドラム式積繊装置が知られている。前記ドラム式積繊装置の一般的構造は、図７に示されるように、供給されるパルプ材料を細かく粉砕するための解繊装置４４と、この解繊装置４４を囲繞するとともに、粉砕された粉砕パルプを空気流に乗せて搬送するための供給路を形成する供給路ケーシング４６と、この供給路ケーシング４６の下流側開口部に配設される積繊装置４７と、この積繊装置４７に対向して設けられた転写ドラム４８とからなる。前記積繊装置４７は、外周面に周方向に適宜の間隔で吸収体成形用凹部５５ａ、５５ａ…を備えるとともに、この吸収体成形用凹部５５ａの底面に多数の吸引孔を有する積繊用回転ドラム５５と、この積繊用回転ドラム５５の内部側に配設される吸引チャンバ５６とからなり、図示しない吸引手段によって前記吸引チャンバ５６内が負圧に維持されることにより前記吸収体成形用凹部５５ａ内に空気搬送された粉砕パルプを積繊させるようになっている。なお、前記供給路ケーシング４６には、高吸収性ポリマーの粉粒物を前記粉砕パルプと共に供給するためのポリマー投入口４５が設けられている。また、前記転写ドラム４８に転写された吸収体Ｓは、バキュームコンベア上を搬送されるクレープ紙５０の上面にバキューム装置４９による吸引により転移され、コンベア上を搬送された後、上面側に不織布からなるセカンドシート５１が積層されるようになっている。   2. Description of the Related Art Conventionally, a drum type fiber stacking apparatus is known as an apparatus for continuously producing an absorbent body used for paper diapers, napkins and the like. As shown in FIG. 7, the general structure of the drum type fiber stacking device is a defibrating device 44 for finely pulverizing the pulp material to be supplied, and surrounding and pulverizing the defibrating device 44. A supply path casing 46 that forms a supply path for carrying the pulverized pulp on an air stream, a fiber stacking device 47 disposed in a downstream opening of the supply path casing 46, and the fiber stacking device 47 It is composed of a transfer drum 48 provided to face. The fiber stacking device 47 includes absorbent molding recesses 55a, 55a,... On the outer peripheral surface at appropriate intervals in the circumferential direction, and has a plurality of suction holes on the bottom surface of the absorber molding recess 55a. The drum 55 and a suction chamber 56 disposed on the inner side of the fiber spinning drum 55, and the suction chamber 56 is maintained at a negative pressure by suction means (not shown), thereby forming the absorber. The pulverized pulp conveyed by air in the recess 55a is piled up. The supply passage casing 46 is provided with a polymer inlet 45 for supplying the superabsorbent polymer particles together with the pulverized pulp. Further, the absorbent body S transferred to the transfer drum 48 is transferred to the upper surface of the crepe paper 50 conveyed on the vacuum conveyor by suction by the vacuum device 49, and after being conveyed on the conveyor, from the nonwoven fabric to the upper surface side. The second sheet 51 is stacked.

また、近年は種々の改良が加えられた吸収体製造装置が幾つか提案されている。例えば、下記特許文献１では、外周面に複数の集積用凹部を有する回転ドラムと、該回転ドラムの外周面に原料を飛散させて供給する原料供給手段とを備え、供給された上記原料を上記回転ドラムの各集積用凹部内に吸引して堆積させ、該原料の堆積物を該各集積用凹部から離型させることにより成形体を連続的に製造する成形体の製造装置が開示されている。
特開２０００−１０７２２１号公報 In recent years, several absorber manufacturing apparatuses with various improvements have been proposed. For example, in the following Patent Document 1, the rotating drum having a plurality of concave portions for accumulation on the outer peripheral surface, and the raw material supply means for supplying the raw material by scattering the outer peripheral surface of the rotating drum, the supplied raw material is the above An apparatus for manufacturing a molded body is disclosed in which a molded body is continuously manufactured by sucking and depositing in each accumulation recess of the rotating drum and releasing the deposit of the raw material from each accumulation recess. .
JP 2000-107221 A

しかしながら、例えば紙おむつやナプキン等は、サイズや仕様等に応じて種々の長手寸法の吸収体が製造されているが、従来の吸収体製造装置を用いた場合には、前記吸収体成形用凹部５５ａの長手寸法が異なる複数の積繊用回転ドラム５５を予め用意しておき、吸収体長手寸法に応じて前記積繊用回転ドラム５５に交換して製造を行う必要があった。そのため、設備費用が嵩む、製造作業に手間がかかるなどの問題があった。   However, for example, in the case of paper diapers and napkins, absorbent bodies having various longitudinal dimensions are manufactured according to the size, specifications, etc., but when the conventional absorbent body manufacturing apparatus is used, the absorbent body forming recess 55a is used. It is necessary to prepare in advance a plurality of stacking drums 55 having different longitudinal dimensions, and to replace the spinning drum 55 for stacking according to the longitudinal dimension of the absorber. For this reason, there are problems such as increased equipment costs and time-consuming manufacturing operations.

そこで本発明の主たる課題は、長さの異なる吸収体を同一の積繊用回転ドラムで製造可能とした吸収体の製造装置を提供することにある。   Then, the main subject of this invention is providing the manufacturing apparatus of the absorber which can manufacture the absorber from which length differs with the same rotating drum for fiber stacking.

前記課題を解決するために請求項１に係る本発明として、外周面に周方向に適宜の間隔で複数の繊維集積用凹部が形成された積繊用回転ドラムを備えるとともに、繊維原反を粉砕する解繊装置及び該解繊装置で粉砕された繊維を空気流に乗せて前記積繊用回転ドラムまで搬送するための繊維供給路からなる繊維供給手段を備えた吸収体の製造装置において、
前記各繊維集積用凹部は、重なり部をもって配置された周方向に隣接する２つの成形板材により構成されるとともに、これら各成形板材は成形板材裏面とドラム回転軸部とを連結する支軸によって支持され、これら各支軸の中間部に一端が連結され、他端部同士が相互に連結された従節を備えるとともに、該従節連結部に設けられた摺動コロを前記積繊用回転ドラムの内部に配設された固定ガイド板のドラム回転中心から一定の半径距離で周方向に連続して形成されたカム溝に係合させた構造とし、
前記固定ガイド板を、ドラム回転中心からの半径距離が異なるカム溝が形成された他の固定ガイド板に交換することにより、前記繊維集積用凹部のドラム周方向長さを変更可能としたことを特徴とする吸収体の製造装置が提供される。 In order to solve the above-mentioned problems, the present invention according to claim 1 includes a spinning drum for stacking fibers in which a plurality of concave portions for fiber accumulation are formed at appropriate intervals in the circumferential direction on the outer peripheral surface, and the raw fiber is pulverized In the manufacturing apparatus of an absorbent body comprising a fiber supply means comprising a fiber supply path for carrying the fiber pulverized by the defibrating apparatus and the fiber crushed by the defibrating apparatus to the rotary drum for stacking fiber,
Each of the concave portions for collecting fibers is composed of two molded plate materials adjacent to each other in the circumferential direction arranged with overlapping portions, and each of these molded plate materials is supported by a support shaft that connects the rear surface of the molded plate material and the drum rotation shaft portion. And a slide joint provided at one end of each of the support shafts, one end of which is connected to each other and the other ends connected to each other. The fixed guide plate disposed inside the drum is engaged with a cam groove formed continuously in the circumferential direction at a constant radial distance from the drum rotation center,
By replacing the fixed guide plate with another fixed guide plate in which cam grooves having different radial distances from the drum rotation center are formed, it is possible to change the drum circumferential length of the fiber accumulation recess. An absorbent manufacturing apparatus is provided.

上記請求項１記載の発明によれば、ドラム回転中心からの半径距離が異なるカム溝が形成された固定ガイド板を予め複数用意しておき、前記固定ガイド板を交換することにより、長さの異なる吸収体を同一の積繊用回転ドラムで製造可能となる。すなわち、前記ドラム回転中心からの半径距離が大きなカム溝を有する固定ガイド板とした場合には、前記従節で連結された支軸同士の交差角が狭められて繊維集積用凹部の長さ寸法を小さく設定でき、前記ドラム回転中心からの半径距離が小さなカム溝を有する固定ガイド板とした場合には、前記従節で連結された支軸同士の交差角が大きくなり繊維集積用凹部の長さ寸法を大きく設定できるようになる。   According to the first aspect of the present invention, by preparing in advance a plurality of fixed guide plates in which cam grooves having different radial distances from the drum rotation center are formed, and replacing the fixed guide plates, Different absorbers can be produced on the same spinning drum for stacking fibers. That is, in the case of a fixed guide plate having a cam groove having a large radial distance from the drum rotation center, the crossing angle between the support shafts connected by the follower is narrowed, and the length dimension of the fiber accumulation recess is reduced. When the fixed guide plate has a cam groove with a small radial distance from the drum rotation center, the crossing angle between the supporting shafts connected by the follower is increased, and the length of the concave portion for collecting fibers is increased. It becomes possible to set a large dimension.

以上詳説のとおり本発明によれば、長さの異なる吸収体を同一の積繊用回転ドラムで製造可能となる。   As described above in detail, according to the present invention, absorbers having different lengths can be manufactured using the same rotary drum for stacking fibers.
