SEPARATING DEVICE AND SEPARATING METHOD OF MATERIAL OF ABSORBENT ARTICLE

摘要

A separating device that separates particulate superabsorbent polymers and liquid absorbent fibers included in a material of an absorbent article. The device includes: a belt member that moves along a predetermined moving direction while receiving the falling material on an upper surface; and an airflow supply mechanism that supplies an airflow in a direction opposite to the moving direction of the belt member, along the upper surface from a downstream side of the moving direction relative to a position where the material falls. In a case the superabsorbent polymers are sent to the downstream side of the moving direction by movement of the belt member, the airflow rolls the liquid absorbent fibers on the upper surface of the belt member and forms fiber balls while regulating movement of the liquid absorbent fibers to the downstream side of the moving direction, to separate the liquid absorbent fibers and the superabsorbent polymers.

1. A separating device that separates particulate superabsorbent polymers and liquid absorbent fibers included in a material of an absorbent article, the separating device comprising:
a belt member configured to move along a predetermined moving direction while receiving the falling material on an upper surface of the belt member; and an airflow supply mechanism configured to supply an airflow in a direction opposite to the moving direction of the belt member, along the upper surface from a downstream side of the moving direction with respect to a position where the material falls, wherein in a case the superabsorbent polymers are sent to the downstream side of the moving direction by way of movement of the belt member, the airflow rolls the liquid absorbent fibers on the upper surface of the belt member and forms fiber balls while regulating movement of the liquid absorbent fibers to the downstream side of the moving direction, to separate the liquid absorbent fibers and the superabsorbent polymers.
