Patent number: 10688777Abstract: A plate cylinder enables a printing plate to be attached thereto and is improved in strength. A plate cylinder is attached to a rotationally driven plate driving shaft, and is configured to mount a cylindrical printing plate attached thereon from a tip end side thereof. The plate cylinder is provided with a plate cylinder main body having a plate mounting surface to which the printing plate is attached. A flat portion is formed on a flat surface positioned further toward a radially inner side than the plate mounting surface. A plurality of hole portions is formed side by side in an axially separated state in the flat portion. A plurality of plate fixing members tightly fixes the printing plate to the plate mounting surface. The plate fixing members are fitted into the hole portions, and are provided to be movable in radially inward and outward directions of the plate cylinder.Type: GrantFiled: February 23, 2016Date of Patent: June 23, 2020Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Tomohiro Oku, Toshihiko Onishi, Toru Kitagawa, Hitoshi Tojima

Patent number: 10654262Abstract: A stopper for assuredly preventing shifting of a cylindrical printing plate mounted on a plate cylinder is provided. A plate cylinder 1 has a plate-mounting surface 12 on which a cylindrical printing plate 3 is fitted from the front end side and mounted. A front stopper 4 is provided on the end portion of the front end side. The front stopper 4 is configured so as to be able to switch between a protruding orientation in which at least a portion of the stopper is positioned so as to protrude to the outside of the plate-mounting surface 12 in the radial direction and a retracted orientation in which the entire stopper is positioned to the inside of the plate-mounting surface 12 in the radial direction.Type: GrantFiled: May 12, 2015Date of Patent: May 19, 2020Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Tomohiro Oku, Toshihiko Onishi, Toru Kitagawa, Hitoshi Tojima

Patent number: 10543708Abstract: A cylindrical printing plate formed with high precision and used for printing on a metal can body, particularly an aluminum or aluminum alloy can body. The forming method of a printing plate forms the printing plate to be mounted on an outer periphery of a cylindrical plate cylinder, and includes a notch forming step of forming a positioning notch in a rectangular elastic material sheet in which a resin layer to be served as a plate section is formed on one surface. A cylindrical material forming step rolls the elastic material sheet in which the positioning notch is formed and overlaps both end portions of the elastic material sheet and joining them in a cylindrical shape. A plate section engraving step engraves a printing pattern on the plate section of the elastic material sheet formed into a cylinder shape.Type: GrantFiled: September 28, 2015Date of Patent: January 28, 2020Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Hitoshi Tojima, Tomohiro Oku

Publication number: 20190284064Abstract: An electrolytic treatment apparatus is provided. The electrolytic treatment apparatus includes: an electrolytic tank having a cathode and an anode: an injecting portion that injects a liquid into the electrolytic tank; at least one diaphragm that partitions an inner space of the electrolytic tank into a cathode-side region including the cathode and an anode-side region including the anode, and makes a liquid in the cathode-side region and a liquid in the anode-side region electrically connected; a cathode-side discharging portion that supplies, to an exhaust gas treatment apparatus, a cathode-side solution generated in the cathode-side region by electrolyzing the liquid; and an anode-side discharging portion that supplies, to a sterilizing apparatus, an anode-side solution generated in the anode-side region by electrolyzing the liquid.Type: ApplicationFiled: June 3, 2019Publication date: September 19, 2019Inventors: Takashi INUI, Hiroyuki TOYOZUMI, Akinori ZUKERAN, Tomohiro OKU, Yuta NAKADA
