Problems solved by technology

[0004] However, in the sheet manufacturing apparatus for absorbent articles disclosed in Document 1, particles that collide with the second sheet on the second conveying wheel bounce upward or sideways, resulting in particles that are generated toward the first sheet. Phenomenon of scattering around the sheet and the second sheet
In particular, particles colliding upward from the central axis of the second conveying wheel will bounce upward relative to the colliding position, thereby increasing the probability that the particles will scatter toward the surroundings.

Embodiment Construction

[0033] figure 1 It is a block diagram of the absorbent sheet manufacturing apparatus 1 which concerns on 1st Embodiment of this invention. The absorbent sheet manufacturing apparatus 1 is one type of sheet manufacturing apparatus for absorbent articles, and manufactures an absorbent sheet by sandwiching particles of an absorbent material between sheets of nonwoven fabric or the like. The absorbent sheet is a sheet for absorbent articles used in absorbent articles such as disposable diapers and light incontinence absorbent pads.

[0034] In the absorbent sheet manufacturing apparatus 1, as the particles of the absorbent material, for example, a partially neutralized polyacrylic acid cross-linked body (polyacrylic acid partially neutralized bridge body), a hydrolyzate of a starch-acrylic acid graft copolymer (starch-acrylic acid graft copolymer) can be used. acrylic acid graft (hydrolyzed product), vinyl acetate-acrylic acid ester copolymer saponification product (acetic acid vin...

Abstract

The sheet manufacturing device for absorbent articles of the present invention is provided with a particle collision surface (224), the particle collision surface (224) is located between the lowermost part of the supply cylinder (21) and the second sheet conveying wheel (41) between and extend downwards from the outer side of the cylinder (211). In addition, a part of the particles discharged from the supply concave part (212) passing through the half-shell part (221) toward the front side in the rotation direction of the supply cylinder (21) collides with the particle collision surface (224), and the particles after the collision The particles are directed onto the first sheet (91) through the particle impact surface (224). Therefore, the particles discharged from the supply cylinder (21) can be prevented from directly colliding with the second sheet (92) on the second sheet conveying wheel (41). This prevents particles colliding with the second sheet (92) from scattering around the first sheet (91) and the second sheet (92).

Description

technical field [0001] The present invention relates to a sheet manufacturing apparatus for absorbent articles. Background technique [0002] Absorbent sheets are conventionally used in absorbent articles such as light incontinence absorbent pads used inside disposable diapers. The absorbent sheets are made by sandwiching particles of superabsorbent resin or the like between two sheets of nonwoven fabric or the like. fixed in between. When producing the absorbent sheet as described above, particles of superabsorbent resin are supplied to one side sheet conveyed at a predetermined speed, and then the other side sheet is laminated on the one side sheet and joined together. [0003] The sheet manufacturing apparatus for absorbent articles disclosed in JP-A-2013-17563 (Document 1) includes: a cylindrical portion (silinda portion) formed on the outer surface of the cylindrical portion to be filled with a superabsorbent resin. a plurality of concave parts of the particles; a fir...
