Patent number: 7100506Abstract: In the plate supplying apparatus of the present invention, various vibrations are provided to a plate secured via suction during a separating operation by causing pad rods 403 to repeat a slight ascent and a pause, and thereafter causing the pad rods 403 to make an abrupt descent, thereby reliably peeling off a slip sheet adhering to the back face of the plate. Further, vibration in the rod-up/down direction is provided to the plate during the separating operation, and the plate is not pushed hard. Thus, it is possible to prevent the plate from being damaged. A raising and lowering motor 52 is driven to lower the cassette 9. A separating operation for peeling off a slip sheet S adhering to the back face of the plate P is performed, and thereafter the plate P secured via suction is turned over and transferred.Type: GrantFiled: October 12, 2005Date of Patent: September 5, 2006Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Morihiro Takeda

Patent number: 7051653Abstract: An image recording material separating/removing device which, by using a single lift-out mechanism section, can lift image recording materials out from plural cassettes along simple loci of movement, and in which a space for providing and withdrawing the cassettes is kept as small as possible. In a cassette housing section, a plurality of cassettes are disposed one above another. Each cassette is offset in a horizontal direction. An amount of offset is set on the basis of a locus of movement of a printing plate at a time when the printing plate is sucked and held by suction cups and lifted up in a vertical direction. At least while the suction cups are moving in the vertical direction, the printing plate is not interfered with by cassettes thereabove, and an emulsion surface of the printing plate is not scratched. Space required for placement of the cassette housing section can be reduced. Moreover, because movement of the suction cups can be simplified, a control system can be simplified.Type: GrantFiled: February 27, 2003Date of Patent: May 30, 2006Assignee: Fuji Photo Film Co., Ltd.Inventor: Tsukasa Ono

Patent number: 7007940Abstract: A banknote store can remove banknotes individually from a stack by light air pressure extending over a substantial area of the banknote, the banknote then being transportable without needing to move the source of the reduced pressure. Banknotes are added individually by using reduced pressure to hold them against a transport belt before they are deposited on the stack.Type: GrantFiled: April 3, 2002Date of Patent: March 7, 2006Assignee: Mars, IncorporatedInventors: Roberto Polidoro, Guillermo Garcia

Patent number: 7007942Abstract: An apparatus and method for lifting, separating and transporting a top panel from a stack of panels through the application sequential suction forces. The apparatus and method uses a vacuum conveying system wherein a sequence of suction forces is exerted from one or more suction apertures. A lift bed located beneath the vacuum conveying system, supports a stack of panels, and can be vertically elevated, causing a top panel from the stack of panels to move within sufficient distance of the vacuum conveying system to allow the sequence of suction forces to lift and separate the top panel. Once the top panel is engaged with the conveyor, the conveyor transports the top panel to a designated location.Type: GrantFiled: March 25, 2003Date of Patent: March 7, 2006Assignee: WPS Industries, Inc.Inventors: Clyde Stearns, Wayne Parks

Patent number: 6981698Abstract: An automatic dispensing machine of substantially flat goods is provided which detects the over-dispensing of goods while accommodating for varying thickness of the substantially flat goods. The automatic dispensing machine includes a table which supports goods such as cards, a suctioning device which pulls the cards, a transporting device which transports the cards after they are pulled by the suctioning device, a position-control device which controls the distance between the uppermost card and the suctioning device. The position-control device is configured to increase the distance between the uppermost card and the suctioning device based on a dispensing signal. The distance between the uppermost card and the suctioning device is then decreased until a predetermined distance is reached.Type: GrantFiled: March 10, 2003Date of Patent: January 3, 2006Assignee: Asahi Seiko Co., Ltd.Inventors: Takahito Yamamiya, Akira Okuyama

Patent number: 6948430Abstract: A conveyor system for transporting a printing plate in a platemaking system includes: a carriage riding on a track and one or more low friction substantially horizontal planar support surfaces provided as a high wear laminate, positioned above the carriage and the track, for supporting the printing plate on the non-emulsion side without the use of rollers, belts, bearings or air cushioning. The carriage includes one or more engagement mechanisms for engaging a bottom, non-emulsion side of the printing plate, and the track includes an air cylinder. The engagement mechanisms can be, for example, suctions cups which engage the plate by a vacuum, suction cups which engage the plate by pressure and adhesion, other adhesive devices, or a mechanical gripper for gripping the plate. The track or linear actuating system is preferably an air cylinder. Alternatively the linear actuating system could include a belt and pulleys, a chain and gears, or a threaded lead screw.Type: GrantFiled: March 23, 2004Date of Patent: September 27, 2005Assignee: Agfa CorporationInventors: Robert Montbleau, John Wolber, Joseph German, Mark Faynzilberg

Patent number: 6935238Abstract: A conveying device for a printing plate precursor which takes the printing plate precursor and an interleaf sheet out from a cassette, and which, along a conveying path to an exposure section, takes-off only the interleaf sheet. When a leading end of the interleaf sheet passes by an interleaf sheet peeling roller disposed on the conveying path, the interleaf sheet peeling roller rotates in a direction opposite to a direction of conveying to the exposure section, and contacts the interleaf sheet, and slack is formed in the interleaf sheet between the interleaf sheet peeling roller and a conveying roller. A slack portion is nipped between two belts and fed to a forked-off path, and the interleaf sheet is removed from the conveying path. It is possible to feed only the printing plate precursor out to the exposure section while continuing to convey the printing plate precursor.Type: GrantFiled: October 8, 2003Date of Patent: August 30, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoshinori Kawamura, Takashi Koizumi, Kazuoki Komiyama, Yoshihiro Koyanagi

Patent number: 6904844Abstract: In a removing/conveying portion of a printing plate removing/supplying device, when one cassette among a plurality of cassettes is empty, the empty cassette is placed on a raising/lowering stand and moved to a loading space. Due to a spur gear being rotated clockwise by a motor, a sliding cover, with which the spur gear is engaging, is moved toward a removing portion such that an opening of a cassette stocker portion is opened. In this way, it is possible to refill and load printing plates from a top side of the cassette stocker portion into the empty cassette positioned at the loading space.Type: GrantFiled: March 24, 2004Date of Patent: June 14, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Takashi Koizumi, Yoshinori Kawamura
