Patent number: 8434761Abstract: A sheet transportation apparatus includes at least one beltless vacuum transport (BVT) that has a plurality of adjacent rollers. Each of the rollers comprises a rounded external surface and an axis about which the external surface rotates. The external surfaces of the rollers are spaced from each other by gaps referred to as “inter-roller spaces.” A fan is positioned on a first side of the rollers. The fan draws air through the inter-roller spaces to create a vacuum force on a second side of the rollers. The vacuum force maintains the sheets of media in contact with the second side of the rollers. The external surface of each of the rollers comprises a plurality of first regions having a first diameter and a plurality of second regions having a second diameter different than the first diameter. The first regions and the second regions of the external surface are adjacent one another and alternate along the length of the external surface of each of the rollers.Type: GrantFiled: February 4, 2011Date of Patent: May 7, 2013Assignee: Xerox CorporationInventors: Erwin Ruiz, Melissa A.

Patent number: 8177231Abstract: A conveying body that can attract and peel-off a recording medium by a simple mechanism, and an image forming device using the conveying body are provided. One end portions of through-holes of a drum are blocked by a blocking member, and a suction member and a blowing-out member are provided at other end portions of the through-holes. Due to a suction pump being operated and suction force being generated within the through-holes via a suction port of the suction member, the suction force passes through the through-holes and acts on long grooves of an outer peripheral surface of the drum, and a sheet can be attracted reliably to the outer peripheral surface of the drum. Further, because air is blown-out from the blowing-out member by operation of the suction pump, a leading end portion of a sheet can be reliably peeled-off from the outer peripheral surface of the drum.Type: GrantFiled: March 27, 2009Date of Patent: May 15, 2012Assignee: Fujifilm CorporationInventors: Takashi Fukui, Tatsuya Nitta

Patent number: 7014187Abstract: A new and improved article or mail-piece conveyor system has a vacuum plenum system integrally incorporated therein which effectively withdraws ambient air ahead or downstream of the oncoming conveyed articles or mail pieces such that the oncoming conveyed articles or mail pieces will not be subjected to tip vortices and/or other disruptive aerodynamic forces. In this manner, the articles or mail pieces will not be subjected to destabilizing aerodynamic circulation, currents, downflow, downwash, or momentum forces so as not to, in turn, exhibit flutter, fluctuations, or oscillation movements. Accordingly, extremely high speed conveyance of the articles or mail pieces, within the range of, for example, two hundred inches per second (200 ips) can in fact be achieved.Type: GrantFiled: June 12, 2003Date of Patent: March 21, 2006Assignee: Lockheed Martin CorporationInventors: Willson L.
