Patent number: 11345137Abstract: In a forward movement, an article is conveyed to a printing device via a transfer position while being kept mounted in a first holder for printing by the printing device. The article is returned to the transfer position together with the first holder after printing. An article to be printed after the above article is mounted into a second holder in parallel with at least a part of the forward movement, the printing and a return movement. This is capable of printing on the articles in a short throughput time also when the articles are those having a three-dimensional shape such as bottles and in-vehicle components.Type: GrantFiled: May 14, 2019Date of Patent: May 31, 2022Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Takuji Kato, Masafumi Kawagoe, Tomoyuki Komura, Shuji Muramoto, Kuniko Teraki

Patent number: 9327488Abstract: A carrier and a substrate are aligned even if an imager cannot be simultaneously focused on alignment marks formed on both the carrier and the substrate. Center of gravity positions G1m of an alignment pattern element AP1 on a substrate and G2m of an alignment pattern element AP2 on a transparent blanket are calculated by image processing from an image IM imaged via the blanket by a CCD camera. The position of the center of gravity Gm2 is specified by a process associated with edge extraction from the image imaged with the alignment pattern element AP2 on the blanket being in focus. High spatial frequency components are removed and low frequency components are extracted for the alignment pattern element AP1 on the substrate imaged out of focus to have a blurred outline, and the position of the center of gravity G1m is specified from an extraction result.Type: GrantFiled: August 30, 2012Date of Patent: May 3, 2016Assignee: SCREEN Holdings Co., Ltd.Inventors: Kazutaka Taniguchi, Masafumi Kawagoe, Mikio Masuichi, Tomoyuki Komura

Patent number: 8955432Abstract: The supply of a negative pressure to an opening P(+1) adjacent to an opening P(0) is stopped by switching a suction valve connected to the opening P(+1) from an open state to a closed state while keeping a positive pressure valve connected thereto closed. Then, near the opening P(+1), a force for holding a blanket becomes gradually weaker against a pressure force in a pressurized space. Associated with that, an air component in the pressurized space flows into a space between a portion of the blanket vertically above the opening P(+1) and an upper surface, whereby the blanket portion is lifted from the upper surface and brought into contact with the lower surface of a printing plate. In this way, a contact area is slowly and stably widened while a sudden change of a pressure in the pressurized space SP5 is suppressed.Type: GrantFiled: August 7, 2012Date of Patent: February 17, 2015Assignee: SCREEN Holdings Co., Ltd.Inventors: Masafumi Kawagoe, Mikio Masuichi, Tomoyuki Komura, Hiroyuki Ueno, Miyoshi Nakajima

Patent number: 8893620Abstract: A print section patterns a coating layer to form a pattern layer on a carrier and then transfers the pattern layer to a substrate. A controller obtains a first carrier thickness by measuring the thickness of the carrier carrying the coating layer and adjusts a gap between the carrier carrying the coating layer and the printing plate based on the first carrier thickness immediately before the coating layer is patterned. The controller also obtains a second carrier thickness by measuring the thickness of the carrier carrying the pattern layer and adjusts a gap between the carrier carrying the pattern layer and the substrate based on the second carrier thickness immediately before the pattern layer is transferred.Type: GrantFiled: October 18, 2012Date of Patent: November 25, 2014Assignee: SCREEN Holdings Co., Ltd.Inventors: Tomoyuki Komura, Mikio Masuichi, Masafumi Kawagoe, Tetsuo Tanaka

Publication number: 20080295769Abstract: A second plate is disposed opposing to a first plate. The second plate is supported by three supporting members which are disposed in a circle about a central axis. The supporting members are provided with extensible portions, respectively and are arranged to be able to extend and contract in a moving direction. A control unit drives to extend and to contract the extensible portions independently to displace the second plate in the moving direction at the supporting portion at which the supporting members support the second plate. Hence, the relative tilt of the second plate relative to the first plate is corrected.Type: ApplicationFiled: April 24, 2008Publication date: December 4, 2008Inventors: Masafumi Kawagoe, Tomoyuki Komura

The apparatus has a positioning mechanism disposed, in a moving passage of a substrate held by the first substrate holding hand, independently from the first substrate transfer mechanism, and having a positioning contact portion for regulating the movement of a substrate such that the substrate is positioned at a predetermined position on the first substrate holding hand.Type: GrantFiled: April 11, 2002Date of Patent: March 30, 2004Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Kenji Fujii, Fuminori Asa, Ryuichi Hayama, Tomoyuki Komura
