  • Patent number: 7029008
    Abstract: 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.

  • Patent number: 7007947
    Abstract: A media storage bin including a floor and a pair of spaced apart walls specifically spaced to receive pieces of media and to retain the pieces of media in a stacked condition. A drop control flap is mounted to an individual one of the spaced walls for delaying the fall of a piece of media into the bin. This wall includes a top surface. A platform for supporting a stack of pieces of media is disposed in the bin, between the wall top surface and the floor. A helical spring is disposed between the platform and the floor for maintaining the top of the media stack at a predetermined distance from the wall top surface to provide thereby a constant fall distance between an individual one of the pieces of media and the wall top surface. This is accomplished in a manner whereby the spring rate enables the platform to drop the thickness of one piece of media for each piece of media added to the top of the stack.

  • Patent number: 6991229
    Abstract: The present invention is to provide a paper stacker for use with an image forming apparatus of a high copying speed. The paper stacker comprises a paper conveying means for conveying a paper with an image recorded thereon to a stacking position, a top end stopper provided reciprocatively movably along a conveying path of the paper, a paper receiving plate disposed below the conveying path of the paper for receiving a paper, a rear end stopper for defining the rear end position of the paper on the paper receiving plate, and an elevating device for changing the height of the paper receiving plate, wherein the top end stopper and the rear end stopper are provided movably in the same direction in the conveyance direction per a given number of papers. The papers are stacked only by shifting the top end stopper and the rear end stopper in the conveyance direction so that the stacker configuration is extremely simplified so as to enable a high speed.

  • Patent number: 6840513
    Abstract: The invention is directed to an automatic mail tray loading device that is adapted to receive envelopes from an inserting machine or from other mail-processing systems and place them in mail trays. The device has a two-stage envelope buffer, which buffers the envelopes into a shingled array before depositing them into the mail tray. The first stage buffers the envelopes during purging of the second stage and the second stage buffers the mail during a tray change. The mail trays are held on a tray conveyor, at an inclination that ensures proper loading of the tray and reliable transfer of envelopes from the tray. The tray conveyor incrementally moves the envelope tray downward until the tray is full of envelopes. A new, empty tray is then moved into position and the filled tray is moved laterally to the tray offload station. The system comprises an envelope conveyor, a tray conveyor, a lateral tray transfer mechanism and an auxiliary buffer.

  • Patent number: 6702278
    Abstract: This invention includes a weighted apparatus for gently holding an existing stack of paper at opposite sides thereof so that a new job may be deposited over the existing stack without degrading the stacking quality of the existing stack. The apparatus may be readily incorporated into many existing paper handling devices which have a paper output tray which is upwardly and downwardly movable in a vertical direction. The apparatus includes a mirror-image pair of paper hold mechanisms, each of which secures a single edge of the existing stack. Each mechanism includes an arm having a longitudinally-oriented slot in a laminar upper end portion thereof and a guide pin anchored to the frame of the paper handling device which passes through the slot. The arm is retained on the pin between a pair of flanged collets. The collets limit movement of the arm within a plane, while the pin constrains the arm to movement along the length of the slot.

  • Patent number: 6695302
    Abstract: Documents are fed in a stream through the first station of a machine that senses the last page of each document along alternative paths in order to accumulate the groups in a staggered stack on a vertically adjustable elevator. When this staggered stack reaches a predetermined number (N) the elevator drops down to off load the stack onto a takeaway conveyor. The documents continue to be accumulated at the second station on a reciprocating support surface that redeposits these additional documents on the elevator when the elevator returns to a raised position and the support surface is retracted.

  • Patent number: 6663102
    Abstract: A configuration controls the height and the inclination of a stacking tray according to the number of sheets discharged and controls the height and the inclination of a stacking tray when discharging sheets and when discharging sheet bundles to improve alignment of discharged sheets and the transporting characteristics. When discharging a sheet bundle, a stacking tray is lowered and when it reaches its home position, the aforementioned stacking tray is stopped. When discharging a sheet, the system determines whether it is the first sheet of a plurality of sheets in a bundle. For the first sheet, a timer is set to a predetermined time from raising to stopping the aforementioned stacking tray (using a pulse count value) and the aforementioned stacking tray is raised. After the set time is up, the stacking tray is stopped at a preset position.
