Abstract
Disclosed is a slitter which comprises: a plurality of slitter heads arranged along and positionally adjustably in a width direction perpendicular to a conveyance direction of a corrugated paperboard, wherein each of the plurality of slitter heads includes a circular slitter blade and a drive motor for rotating the slitter blade; a blade radius acquisition unit operable to acquire respective radii of the plurality of slitter blades; and a control unit operable, based on the radii of the plurality of slitter blades acquired by the blade radius acquisition unit, to control respective rotational speeds of the plurality of drive motors so as to allow respective blade edges of the plurality of slitter blades to have the same circumferential speed.
Claims7
A slitter comprising:
- a plurality of slitter heads arranged along and positionally adjustably in a width direction perpendicular to a conveyance direction of a corrugated paperboard, each of the plurality of slitter heads including a circular slitter blade and a drive motor for rotating the slitter blade;
- a blade radius acquisition unit operable to acquire respective radii of the plurality of slitter blades;
- and
- a control unit operable, based on the radii of the plurality of slitter blades acquired by the blade radius acquisition unit, to control respective rotational speeds of the plurality of drive motors so as to allow respective blade edges of the plurality of slitter blades to have a same circumferential speed.
A slitter control program executable by a computer for a slitter, wherein the slitter comprises:
- a plurality of slitter heads arranged along and positionally adjustably in a width direction perpendicular to a conveyance direction of a corrugated paperboard, each of the plurality of slitter heads including a circular slitter blade and a drive motor for rotating the respective slitter blades;
- and
- a blade radius acquisition unit operable to acquire respective radii of the plurality of slitter blades, the slitter control program being configured to cause the computer to perform a control processing of, based on the radii of the plurality of slitter blades acquired by the blade radius acquisition unit, controlling respective rotational speeds of the plurality of drive motors so as to allow respective blade edges of the plurality of slitter blades to have a same circumferential speed.
