Patent number: 9284150Abstract: An apparatus for manufacturing absorbent articles includes: a detecting section detecting an edge position of a continuous sheet in the width direction when the detecting section is stopped at a stop position, a meandering correcting section correcting meandering of the continuous sheet, a motor moving the detecting section in the width direction, and a controller controlling the motor based on a movement signal related to movement of the detecting section. The controller has a value corresponding to a distance from a reference position to each stop position, moves the detecting section to each stop position based on the corresponding value and the movement signal. The controller detects that the detecting section reaches the reference position based on a current of the motor. The reference position is a limit position for physical movement in the width direction of the detecting section, and is at or outside the outermost stop position.Type: GrantFiled: July 20, 2011Date of Patent: March 15, 2016Assignee: UNICHARM CORPORATIONInventor: Takumi Nakano

Patent number: 9101512Abstract: An absorbent-body manufacturing apparatus manufactures an absorbent body by depositing absorbent-body material in a plurality of recess sections spaced at an arrangement pitch on an outer circumferential face of a drum. The apparatus has a driving source that drives the drum in synchronization with another apparatus based on a synchronization signal. First and second signal-generating sections repeatedly generate first and second rotational-angle signals based on a rotation of the drum with a rotational angle of the drum as a unit, the rotational angle of the drum corresponding to first and second pitches, respectively. Depending on whether the arrangement pitch is set to the first or second pitch, a controller controls rotational driving operation of the driving source based on the first or second rotational-angle signal and on the synchronization signal.Type: GrantFiled: March 17, 2011Date of Patent: August 11, 2015Assignee: UNICHARM CORPORATIONInventor: Takumi Nakano

Patent number: 9096405Abstract: In a defective-workpiece discharging device, a defective workpiece is discharged to a discharge path from a conveyance path that conveys a plurality of workpieces related to absorbent articles at a predetermined conveyance pitch. The conveyance path has a first path and a second path downstream of the first path. A sorting mechanism between the first and second paths sorts workpieces into either the second path or the discharge path. A defect detection sensor detects a defect and outputs a defect detection signal. A passage detection sensor detects passage of the workpieces at a predetermined position on the first path and outputs a passage detection signal. A controller controls the sorting mechanism based on the defect and passage detection signals. An end of the first path on the sorting mechanism side and the predetermined position are separated by a distance greater than or equal to the conveyance pitch.Type: GrantFiled: March 17, 2011Date of Patent: August 4, 2015Assignee: UNICHARM CORPORATIONInventor: Takumi Nakano
