PROBLEM TO BE SOLVED: To supply a uniform amount of particles in a width direction onto a continuous sheet continuously and stably.SOLUTION: A particle supply device 1 includes a cylinder part 21 having an outside surface 211 which is a flat tubular surface centering on a horizontal rotary shaft J1, a tank part 3 for continuously supplying particles of an absorbent material onto the outside surface 211 from a supply port adjacent to the outside surface 211 of the cylinder part 21 near immediately above the rotary shaft J1, and a conveyance mechanism for continuously conveying a continuous sheet in a horizontal direction perpendicular to the rotary shaft J1 below the cylinder part 21. The tank part 3 includes: a front plate member 35 disposed on a front side of the supply port in a rotational direction of the cylinder part 21, to form a microgap 81 between a lower edge 351 parallel to the rotary shaft J1 and the outside surface 211 and a pair of side plate members 36 that limit a range where the particles pass through the microgap 81 together with the outside surface 211, in the width direction parallel to the rotary shaft J1. A uniform amount of particles can be supplied in a width direction onto a continuous sheet continuously and stably.COPYRIGHT: (C)2013,JPO&INPIT【課題】幅方向に均等な量の粒子を連続シート上に連続的に安定して供給する。【解決手段】粒子供給装置1は、外側面211が水平な回転軸J1を中心とする平らな円筒面であるシリンダ部21と、回転軸J1の真上近傍にてシリンダ部21の外側面211に近接する供給口から外側面211上に吸収材料の粒子を連続的に供給するタンク部3と、シリンダ部21の下方にて回転軸J1に垂直な水平方向に連続シートを連続的に搬送する搬送機構とを備える。タンク部3は、シリンダ部21の回転方向における供給口の前側に配置され、回転軸J1に平行な下エッジ351と外側面211との間に微小隙間81を形成する前方板部材35と、回転軸J1に平行な幅方向に関して、外側面211と共に粒子が微小隙間81を通過する範囲を制限する一対の側方板部材36とを有する。これにより、幅方向に均等な量の粒子が連続シート上に連続的に安定して供給される。【選択図】図2
