Patent number: 11919112Abstract: A machine tool includes a bed including a bottom surface and legs arranged at three positions of the bottom surface. The bed includes two oblique sides arranged such that the bottom surface has a triangular shape. The machine tool also includes a first support surface arranged on the bed and extending along a substantially horizontal first axis, a work table supported by the first support surface so as to move along the first axis, a second support surface arranged on the bed and extending along a substantially horizontal second axis, which is perpendicular to the first axis, and a machining unit supported by the second support surface so as to move along the second axis. The second support surface is located higher than the first support surface.Type: GrantFiled: March 7, 2023Date of Patent: March 5, 2024Assignee: NAGASE INTEGREX CO., LTDInventors: Ryota Shindo, Keiji Uemura

Publication number: 20230302823Abstract: The anti-drop members 7l and 7r are provided to each of the air turn bars 6u and 6l, and the respective anti-drop peripheral surfaces 711 of the anti-drop members 7l and 7r adjoin the support peripheral surface 611 of each of the air turn bars 6u and 6l. In this configuration, on the occurrence of oblique traveling of the printing medium M, the printing medium M is deviated from the support peripheral surface 611 of each of the air turn bars 6u and 6l to the anti-drop peripheral surface 711 of the anti-drop member 7l or 7r. Specifically, the anti-drop peripheral surface 711 of each of the anti-drop members 7l and 7r allows the printing medium M to be supported while providing the clearance ? from the front surface M1 of the printing medium M deviated by the oblique traveling.Type: ApplicationFiled: February 13, 2023Publication date: September 28, 2023Inventors: Kenta Hiramatsu, Yoshikuni TAKEICHI, Ryota UEMURA

Patent number: 11590774Abstract: The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.Type: GrantFiled: March 4, 2021Date of Patent: February 28, 2023Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Kenta Hiramatsu, Yoshikuni Takeichi, Takeshi Matsuda, Keisuke Hirai, Ryota Uemura

Patent number: 11453227Abstract: In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.Type: GrantFiled: March 4, 2021Date of Patent: September 27, 2022Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Ryota Uemura, Keisuke Hirai, Yoshikuni Takeichi, Takeshi Matsuda, Kenta Hiramatsu

Patent number: 11345174Abstract: The printing medium M after color printing is performed on the front surface M1 (recording surface) by the color printing unit 32 can be conveyed while the front surface M1 and the back surface M2 of the printing medium M are inverted twice by the only rollers 471 to 478 (rotary bodies) in contact with the back surface M2 (non-recording surface) of the printing medium M (inverting conveying part 47). In this way, without providing air turn bars, a time to convey the printing medium M from the color printing unit 32 to the white printing unit 33 can be secured while the printing medium M is firmly supported by the rollers 471 to 478 in contact with the back surface M2 of the printing medium M.Type: GrantFiled: March 4, 2021Date of Patent: May 31, 2022Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Shinsuke Yamashita, Keisuke Hirai, Kazuhiko Asada, Ryota Uemura

Patent number: 11215398Abstract: A web drying apparatus, comprises: two blower units which are arranged vertically between an upper dry path and a lower dry path disposed below the upper dry path and at least partially overlap each other when viewed from a vertical direction. One blower unit disposed on an upper side, the other blower unit disposed on a lower side. The lower end part of the one blower unit deviates from the upper end part of the other blower unit in the horizontal direction and protrudes to be lower than the upper end part in the vertical direction.Type: GrantFiled: February 28, 2020Date of Patent: January 4, 2022Assignee: SCREEN HOLDINGS, CO., LTD.Inventors: Takeshi Matsuda, Yoshikuni Takeichi, Kenta Hiramatsu, Keisuke Hirai, Ryota Uemura
