Particle supplying apparatus and sheet article manufacturing apparatus

摘要

An absorbent sheet manufacturing apparatus has a cylinder part having a plurality of concave portions arranged in a circumferential direction, a particle filling part which is located above the cylinder part and which stores particles of high-absorbent resin, to sequentially fill the plurality of concave portions with particles by a particle filling opening in its lower end, and a communication part which is located adjacent to the particle filling opening. A concave portion facing a posterior edge of the particle filling opening is brought into communication with external space through the communication part. Therefore, when particles are filled into the concave portion from the particle filling part, air in the concave portion is forced out by particles entering the concave portion and is easily discharged to the external space through the communication part. As a result, it is possible to increase a density of particles filled in the concave portion.

主权项

1. A particle supplying apparatus for supplying particles of absorbent material or deodorant material onto a sheet member, comprising:
a cylinder part which has an generally cylindrical shape rotated around a rotation axis along a horizontal direction, said cylinder part having a plurality of concave portions arranged in a circumferential direction on an outer side surface thereof; a particle filling part which is located above said cylinder part and which stores particles of absorbent material or deodorant material, to sequentially fill said plurality of concave portions with particles by a particle filling opening which faces said outer side surface of said cylinder part; a first cover part which spreads from said particle filling opening along a rotation direction of said cylinder part to cover a portion of said outer side surface of said cylinder part; a second cover part which spreads from said particle filling opening along an opposite direction of said rotation direction to cover another portion of said outer side surface of said cylinder part; a communication part which is located adjacent and posterior to said particle filling opening in said rotation direction, a concave portion out of said plurality of concave portions being in communication with external space through said communication part, said concave portion facing a posterior edge of said particle filling opening; and a sheet conveying part for conveying a sheet member in a direction under an anterior edge of said first cover part in said rotation direction, said direction being same as a moving direction of said outer side surface of said cylinder part.
