It is in a state of overlapping in the thickness direction. Therefore, when the granular material S is supplied to the surface of the first sheet 201 in this state, the granular material S does not enter the inside of the first sheet 201 and is only placed on the surface thereof. Become. Therefore, even if the granular material S on the first sheet 201 is covered with the second sheet 202, the granular material S can freely move between the two sheets 201 and 202 along the surface of the first sheet 201.
- the position of the granular material S is not stable. Like the granular material-containing article manufactured by the apparatus of International Publication No. 2014/104118, the user may feel uncomfortable and the desired liquid absorption performance. There is a risk that sufficient performance such as the above cannot be obtained. Moreover, when the granular material S has liquid absorbency, since the granular material S is biased and the granular materials S come into contact with each other, when the liquid is absorbed at the time of use, the contacting granular materials S are in contact with each other. However, there is a possibility that the phenomenon of restricting the other expansion, that is, a so-called gel block phenomenon occurs, and the liquid absorption performance of the granular material-containing article 2 may deteriorate.

Therefore, the granular material S can be dispersed and arranged in the first sheet 201 (short fiber sheet 201b) in the thickness direction. Therefore, each granular material S can be individually embedded in the space, and fibers can be more reliably interposed between the granular materials S.
- the suction port 51a of the suction device 50 is provided between a position immediately below the spray port 48c, that is, a position facing the spray port 48c and a position downstream of the spray port 48c in the transport direction Y1 of the first sheet 201.
- the suction force by the suction device 50 is suppressed from being applied to the first sheet 201 before the granular material S is supplied. Therefore, before the granular material S is supplied, it is possible to prevent the fibers raised by this suction force from being turned down, and a space is formed between the fibers, so that the granular material S is surely provided in this space. Can get in.
- the diffusion sheet 201a constituting the back surface of the first sheet 201 and the vicinity thereof is not raised. Therefore, the density of the back surface of the first sheet 201 and the vicinity thereof can be maintained higher than that of the front side portion, and the granular material S can be contained in the first sheet 201 from the front side as described above. It is possible to efficiently disperse and dispose the granular material S in the first sheet 201 while preventing the granular material S from slipping through the back side of the first sheet 201 while entering and appropriately dispersing.

- the first sheet 201 and the second sheet 202 are pressed against each other by the pressing device 70. Therefore, the thickness of the granular material-containing article 2 can be kept small. Furthermore, since the granular material S is firmly pressed by surrounding fibers by suppressing the thickness to be small, the movement of the granular material S in the direction along the surface of the granular material-containing article 2 can be suppressed. It is possible to stably arrange the granular material at a more appropriate position.

- the moving speed of the blade 34 is larger than the conveying speed of the first sheet 201, and the first sheet 201 is moved to the blade. Even if the first sheet 201 is relatively moved from the downstream side in the moving direction of the blade 34 toward the upstream side, the first sheet 201 can be brought into contact with the downstream portion in the moving direction of the blade 34 and raised. However, in this case, it is necessary to move the blade 34 at a high speed, and when the blade 34 abuts on the surface side of the first sheet 201, the fibers of the first sheet 201 are scooped in the transport direction by the blade 34. It is hard to be raised because it is pushed.
- the moving direction Y3 of the blade 34 is made the same as the conveying direction Y1 of the first sheet 201, and the moving speed of the blade 34 is made smaller than the conveying speed of the first sheet 201.

Abstract
Description
図1は、本発明の第1実施形態に係る粉粒体含有物品の製造装置1(以下、単に製造装置1という)を示した概略図である。図1に示すように、この製造装置1は、第1シート搬送装置(シート搬送装置)10と、第2シート搬送装置20と、起毛装置30と、粉粒体供給装置40と、吸引装置50と、折り曲げ装置60と、圧接装置70と、第1接着剤塗布装置82と、第2接着剤塗布装置84とを備える。
第1シート搬送装置10は、第1シート201を搬送するための装置である。第1シート搬送装置10は、ベルトコンベア18と、複数のガイドロール11,12,13とを備える。第1シート搬送装置10は、ベルトコンベア18がモータ等によって駆動されることで、第1シート201を搬送路L1に沿って図1の矢印Y1の方向に搬送して起毛装置30、粉粒体供給装置40、第2接着剤塗布装置84、折り曲げ接合装置60、圧接装置70に、それぞれこの順で送り込む。
起毛装置30は、第1シート201をその表側から起毛させるための装置である。
粉粒体供給装置40は、第1シート201に第1シート201の表側から粉粒体Sを供給する装置である。
吸引装置50は、ベルトコンベア18上の第1シート201をその裏側から吸引するための装置である。
第1接着剤塗布装置82は、第2シート202に接着剤を塗布する装置である。例えば、第1接着剤塗布装置82は、ホットメルト接着剤を第2シート202に塗布する。第1接着剤塗布装置82は、前記のように第2シート202の搬送路のうちガイドロール21の上流側の位置に配置されており、第1シート201の表面に供給される前の第2シート202の表面に接着剤を塗布する。
圧接装置70は、互いに接合された第1シート201と第2シート202とをこれらの厚み方向に圧接するための装置である。本実施形態では、圧接装置70は一対のローラ72,72を備え、これらローラ72,72の間を第1シート201と第2シート202とが通過することでこれらをその厚み方向に圧接する。
前記のように構成された製造装置1によって粉粒体Sを含有する粉粒体含有物品2を製造する方法は次のようになる。
以上のように、本実施形態に係る製造装置1および前記粉粒体含有物品の製造方法では、粉粒体Sが第1シート201に供給される前に、第1シート201のうちその表面に露出する短繊維シート201bがその表側から起毛される。
前記第1実施形態では、粉粒体散布装置46に第1シート201を搬送する装置として、ベルトコンベア18を用いた場合について説明したが、図6に示すように、ベルトコンベア18に代えて搬送ドラム518を用いてもよい。この場合には、搬送ドラム518の外周面に起毛後の第1シート201を供給し、搬送ドラム518の外周面上で第1シート201に粉粒体Sを供給するとともに、搬送ドラム518の外周面上でガイドロール21により第1シート201に第2シート202を供給する。そして、ガイドロール21と搬送ドラム518との間で、第1接着剤塗布装置82により接着剤が塗布された第2シート202と第1シート201とをこれらの厚み方向に圧接しつつ互いに接合する。また、搬送ドラム518の外周面に空気穴を形成し、この空気穴と吸引装置50とを連通させて、これら空気穴を介して第1シート201をその裏側から吸引すればよい。
前記第1実施形態では、第2シート202を第1シート201の表面に供給する第2シート搬送装置20のガイドロール21を、散布口48cと対向する位置よりも下流側、すなわち、第1シート201に粉粒体Sが供給される位置よりも下流側(第1シート201の搬送方向Y1について)に配置した場合について説明したが、これに代えて、図7および図7の一部を拡大して示した図8のように配置してもよい。
ここで、粉粒体Sとして、単一の吸収性を備えたSAPを用いてもよいが、吸液性の高いSAPと、吸収速度が速いSAPとを混ぜたものを用いてもよい。例えば図1に示す粉粒体貯留装置42の一方のタンク42aに吸液性の高いSAPを収容し、他方のタンク42bに吸収速度が速いSAPを収容して、両タンク42a、42bから所定の比率でそれぞれSAPを供給することなどが考えられる。
