Publication number: 20070273086Abstract: A method for stacking objects in a container including the step of measuring a thickness value of each object at a plurality of predetermined locations along a face surface of the respective object. A cumulative thickness profile is developed indicative of a plurality of stacked objects, i.e., juxtaposed along each face surface. The cumulative thickness profile is, furthermore, calculated by summing each of the measured thickness dimensions at each of the predetermined locations. Next, a maximum thickness value is determined as each of the objects is measured and compared to a maximum fill value for each container to determine an overfill condition/number. The overfill condition corresponds to the number of objects which additively cause the maximum thickness value to exceed the maximum fill value. The objects may then be stacked based upon the overfill condition such that the total number of objects is less than the number corresponding to the overfill condition.Type: ApplicationFiled: May 26, 2006Publication date: November 29, 2007Applicant: Pitney Bowes IncorporatedInventor: Denis J.

Patent number: 6471204Abstract: In an image recording apparatus with excellent quality which can prevent image degradation and the like due to stacking too much recording material on a discharge tray, when the recording operation is carried out, a sensor measures the distance from the upper surface of a flapper to the stacked object. The output obtained here is taken in by a distance detecting circuit. After a calculation circuit carries out comparison and calculation, the distance is calculated and is transmitted to a control circuit. By comparing the calculated distance with thickness data with regard to the recording material and the like stored in advance in a memory device in the control circuit, the allowable residual amount of stack and the allowable residual number of sheets of stack are further presumed.Type: GrantFiled: June 14, 2000Date of Patent: October 29, 2002Assignee: Canon Kabushiki KaishaInventor: Hiroyuki Tamaki

Patent number: 6454255Abstract: A sheet accumulator has a circular paper path and a compact design. Individual sheets of paper moving along a main linear path are diverted into the accumulator one by one, and each sheet enters a gripper having jaws that grip the sheets of paper. The gripper jaws pull the sheets along the circular paper path until the gripper returns to a home location, at which point the gripper stops, opens, accepts another sheet, closes, and makes another rotation. When the accumulation is complete, the gripper jaws open to release an accumulated stack of sheets, and a roller is then engaged to exit the sheets out of the accumulator and into the main linear paper path.Type: GrantFiled: December 19, 2000Date of Patent: September 24, 2002Assignee: Pitney Bowes Inc.Inventors: Robert J.

Patent number: 6378860Abstract: A system has a media handler to transports media (e.g., paper, transparencies, etc.) from an input bin through a processing unit to a collection tray. A tray adjustment mechanism moves the collection tray down and up as media is collected and occasionally removed by the operator. An overload detector detects an overload condition when the media stack on the tray becomes too heavy. The overload detector indirectly measures the stack weight by measuring the speed of the tray (or media stack) or alternatively, by monitoring the motor current. Once overload is detected, the system stops the tray to avoid damaging the tray adjustment mechanism and/or tray. The system notifies the operator via a visual message or an audible alarm. A recovery manager is then invoked to return the tray to the appropriate position after the operator has removed the media stack. In user-assisted recovery, the system awaits some explicit input from the operator that the media stack has been removed.Type: GrantFiled: July 21, 1999Date of Patent: April 30, 2002Assignee: Hewlett-Packard CompanyInventors: Hernan Gutierrez, Antonio Martinez, Raul Ocampo
