Patent number: 7029008Abstract: To provide an accumulating device 71 that is capable of securely accumulating sheets or the like P having dimensional differences on the basis of the rear ends in the taking-in direction thereof. The stopper 111a advances from upward to the advanced position between the tip end regulating wall 79 and the rear end regulating wall 80 and stops the tip ends in the taking-in direction of sheets or the like P to be taken in, whose length in the taking-in direction of sheets or the like P is shorter than the maximum length. The stopper 111a is supported movably in the vertical direction with respect to the advancing and retreating mechanism by which the stopper 111a is caused to advance and retreat between the advanced position and the retreated position, and presses sheets or the like P in the downward direction.Type: GrantFiled: October 28, 2003Date of Patent: April 18, 2006Assignee: Glory Ltd.Inventors: Mitsuo Nishida, Toshihiko Kobayashi, Tsuguo Mizoro, Toyoshige Kuroiwa, Kosaku Fukuda

Patent number: 6918733Abstract: A hold down clamp for holding down a stack of sheet material, preferably on a transportation trolley selectively in operative association with a printing machine. The hold down clamp has a vertically adjustable holding arm selectively lockable along a substantially upright guide member. The holding arm has at least one release member for releasing locking, the release member being movable in the direction away from the stack. This allows the holding arm to be pliable upwardly in case of emergency.Type: GrantFiled: October 22, 2002Date of Patent: July 19, 2005Assignee: Eastman Kodak CompanyInventors: Ingo Neuber, Dirk Dobrindt

Patent number: 6880823Abstract: A sheet collection apparatus has a stacking portion to stack mails in the standing position, a back-up plate in contact with one end of stacked mails in the stacked direction, and take-in rollers arranged at the positions contacting the other end of stacked mails. The take-in rollers are rotated at a slower peripheral speed than the conveying speed of mails taken in the stacking portion.Type: GrantFiled: April 11, 2003Date of Patent: April 19, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Shinichi Itoh, Naruaki Hiramitsu

Publication number: 20040207150Abstract: A material deflector plate system adapted for mounting below the forwardly declining surface of a material-guiding discharge chute includes a base frame for mounting rearwardly of the discharge edge of the declining surface and a deflector-plate support structure reciprocably depending from the base frame for reciprocation between rearwardmost and forwardmost positions. Hingedly depending from the support structure are alternatively collapsible and deployable first and second deflector plate sets. The system can alternatively assume storage and operative attitudes. A storage attitude is one in which the deflector plate sets are collapsed and the support structure is disposed sufficiently rearwardly with respect to the base frame that at least a majority of the length of the collapsed deflector plate sets is disposed rearwardly of the chute discharge edge.Type: ApplicationFiled: April 16, 2003Publication date: October 21, 2004Inventor: Louis J. Hendzel

Patent number: 6682067Abstract: An apparatus for stacking articles on edge is provided which has a discharge magazine for stacking the articles face-to-face and on-edge. The magazine has an article edge receiver having a non-offset position and an offset position. The article edge receiver has a register wall for aligning the articles in the non-offset position and a segmented rotational offset disk for aligning the articles in the offset position. The disk has a cut out segment having a planar stop edge surface. The cut out segment is rotatable from an article receiving position to an article bypass position. When in the receiving position, the planar stop edge surface is at a right angle to the two faces of the article. When in the article bypass position, the segmented rotational offset disk allows the articles to bypass the segmented rotational disk.Type: GrantFiled: August 26, 2002Date of Patent: January 27, 2004Assignee: KFW Automation, Inc.Inventors: Joseph J. Keane, Donato C. Farole, Glenn A. Nester
