Apparatus for Manufacturing Absorbent Articles and Method for Manufacturing Absorbent Articles

摘要

An apparatus for manufacturing absorbent articles includes: a swinging mechanism that feeds an elastic member while swinging the elastic member along a cross direction crossing a conveyance direction of a sheet-shaped continuum constituting an absorbent article, and that disposes a part of the elastic member on the continuum; a guiding member that conveys the elastic member; a cutting mechanism that cuts the elastic member; a joining mechanism that conveys the elastic member and the continuum that are supplied from the guiding mechanism to be taken along an outer periphery of the joining mechanism; and a sheet supply mechanism that supplies a sheet member onto an end portion in the cross direction of the continuum. A tangential direction of a deviation point at which the continuum is spaced from the guiding mechanism and a tangential direction of an arrival point at which the continuum reaches the joining mechanism are coincident with each other.

1. An apparatus for manufacturing absorbent articles, comprising:
a swinging mechanism that feeds an elastic member while swinging the elastic member along a cross direction crossing a conveyance direction of a sheet-shaped continuum constituting an absorbent article, and that disposes a part of the elastic member on the continuum to which an adhesive is applied; a guiding member that conveys the elastic member and the continuum to be taken along an outer periphery of the guiding member with a guide mechanism shaft being a center of swivel rotation; an outside pressing mechanism that presses the elastic member disposed outer side in a cross direction than the continuum of the elastic member disposed in a predetermined wavy shape by the swinging mechanism; a cutting mechanism that cuts the elastic member conveyed by the guiding mechanism between the outside pressing mechanism and the continuum in the cross direction; a joining mechanism that conveys the elastic member and the continuum that are supplied from the guiding mechanism to be taken along an outer periphery of the joining mechanism with a joining mechanism shaft being a center of swivel rotation; and a sheet supply mechanism that supplies a sheet member onto an end portion in the cross direction of the continuum that is conveyed by the joining mechanism, wherein a tangential direction of a deviation point at which the continuum is spaced from the guiding mechanism and a tangential direction of an arrival point at which the continuum reaches the joining mechanism are coincident with each other the joining mechanism has: a first joining roll having an outer periphery on which the end portion in the cross direction of the continuum and the sheet member are disposed, and rotating with the joining mechanism shaft being a center of swivel rotation; and a second joining roll having an outer periphery on which a region other than the end portion in the cross direction of the continuum is disposed, and rotating with the joining mechanism shaft being a center of swivel rotation, the outer periphery of the first joining roll is made of an elastic member, a radius of swivel rotation of the outer periphery of the first joining roll is greater than a radius of swivel rotation of the outer periphery of the second joining roll, and the joining mechanism comprises a driving mechanism that rotationally drives only the second joining roll of the first joining roll and the second joining roll.
