PROBLEM TO BE SOLVED: To provide a particle supplying apparatus capable of increasing a density of particles to be supplied to concave portions.SOLUTION: An absorbent sheet manufacturing apparatus includes: a substantially cylindrical cylinder part 21 having a plurality of concave portions 212 arranged in a circumferential direction a particle filling part 23 for storing particles of high-absorbent resin in the upper part of the cylinder part 21, and filling the plurality of concave portions 212 of the cylinder part 21 with particles through a particle filling opening 232 in its lower end and a communication part 26 located adjacent to the particle filling opening 232. A concave portion 212a opposing the particle filling opening 232 at a posterior edge of the particle filling opening 232 is brought into communication with external space through the communication part 26. Thus, when particles are filled into the concave portion 212a from the particle filling part 23, air in the concave portion 212a is forced out by particles entering the concave portion 212a and is easily discharged to the external space through the communication part 26. As a result, it is possible to increase a density of particles filled in the concave portion 212a.COPYRIGHT: (C)2013,JPO&INPIT【課題】粒子供給装置において、凹部に充填される粒子の密度を増大させる。【解決手段】吸収シート製造装置は、周方向に配列された複数の凹部212を有する略円筒状のシリンダ部21、シリンダ部21の上方にて高吸収性樹脂の粒子を収容するとともに下端の粒子充填口232を介してシリンダ部21の複数の凹部212に粒子を充填する粒子充填部23、および、粒子充填口232に隣接して配置される連通部26を備える。連通部26は、粒子充填口232の後縁にて粒子充填口232に対向する凹部212aと外部空間とを連通させる。これにより、粒子充填部23から凹部212aに対する粒子の充填が行われる際に、凹部212a内のエアが、凹部212aに流入する粒子に押し出され、連通部26を介して外部空間へと容易に排出される。その結果、凹部212aに充填される粒子の密度を増大させることができる。【選択図】図2
