Patent number: 7555983Abstract: A plate handling apparatus includes a loader, first and second air cylinders, and first and second detection units. The loader is supported to be movable substantially parallel to a paper convey direction and swingable in directions to come close to and be spaced apart from an outer surface of a plate cylinder to perform plate removal/supply. The first air cylinder moves the loader among a first position close to the plate cylinder, a second position spaced apart from the first position in the paper convey direction, and a third position which is between the first position and the second position. The second air cylinder swings the loader among a first swing state where the loader is substantially perpendicular to the paper convey direction, a second swing state where the loader is inclined such that its distal end faces the plate cylinder, and a third swing state which is between the first swing state and the second swing state.Type: GrantFiled: May 31, 2006Date of Patent: July 7, 2009Assignee: Komori CorporationInventors: Kazuya Iyokawa, Kazunori Takeda

Patent number: 6820549Abstract: A rotary press includes a printing unit, folding machine, dancer roller, motor, tension detection unit, and control unit. The printing unit prints on a web supplied from a winding roll. The folding machine folds the printed web supplied from the printing unit. The dancer roller retreats from and advances to a web traveling path between the printing unit and the folding machine, during printing and plate mounting, respectively, to come into contact with the web. The motor selectively, rotatably drives the winding roll in a reel-out direction and a winding direction. The tension detection unit detects a tension of the web between the winding roll and the printing unit. The control unit controls the motor on the basis of a detection result of the tension detection unit during plate mounting.Type: GrantFiled: August 18, 2003Date of Patent: November 23, 2004Assignee: Komori CorporationInventors: Kazuya Iyokawa, Kazushi Noguchi

Patent number: 6216594Abstract: A plate replacing system has a cassette capable of accommodating a new printing plate. The cassette is held at a fulcrum supported by a frame. A front end of the cassette turns about the fulcrum, and can contact and be retracted from a plate cylinder. Inside the cassette, an automatic mounting mechanism including long and short links and an air cylinder is provided for deforming the new plate so as to make a leading edge of the new plate bend. There is a gripping support side surface of a gap in the plate cylinder, which is parallel to the bend while moving a holding member, such as suction pads, which holds the leading edge of the new plate, from a waiting position to an inserting position.Type: GrantFiled: December 9, 1998Date of Patent: April 17, 2001Assignee: Komori CorporationInventors: Takeaki Nakano, Kazuya Iyokawa
