  • Patent number: 6976801
    Abstract: The present invention describes a double belt transport system for moving a mailpiece into a printing area of a digital printer. The transport system includes an upper belt and a lower belt. The upper belt has a straight section to form a nip with the lower belt to ingest the mailpiece. The straight section also defines a registration plane to register the upper surface of the mailpiece with respect to the print head of the printer. In order to make sure the registration is consistent regardless of the thickness of the mailpiece, an up-lifting mechanism is used to push the bottom of the mailpiece in an upward direction against a shield plate, which is positioned substantially on the registration plane. A velocity measurement device, such as an optical encoder, is used to measure the moving speed of the belts so that the printing speed of the digital printer matches the moving speed of the mailpiece in the print area.

  • Patent number: 6328440
    Abstract: An approach for managing the thermal stresses introduced into a heated belt of the type used for transporting media through an ink-jet printer so that the portion of the belt that transports the print media through the print zone does not buckle. The temperature of the belt is controlled to ensure that any temperature gradient produced in the belt is not great enough to buckle the belt in the print zone. Put another way, the temperature profile in the belt is substantially flat. As another approach to the present invention, the belt is bent in the print zone to create a force component in the belt for resisting thermal stress and to increase the belt area moment to greatly enhance resistance to buckling of the belt.

  • Patent number: 6045278
    Abstract: An apparatus for transporting and for printing print media has an inclined guide plate and a transport mechanism orthogonal to this guide plate and an auxiliary device. An ink jet print head controlled by a control unit is rigidly arranged in a recess of the guide plate during printing. The recess is fashioned such that the print medium has a printed region lying free downstream. The print medium transported with the transport mechanism lies without any mechanical clamping against the auxiliary device, that has an ascending guide and allows a defined slippage perpendicular to the transport mechanism surface. Independently of the slope of the floor area of the machine, a non-contacting printing with the ink print head ensues with high print quality for print media transported standing or lying. A placement device precedes the guide plate for the adaptation of the inclination angle .alpha..

  • Patent number: 5207331
    Abstract: A system and method for automatically processing a supply of cartons, in flattened form and of different types, in accordance with a selectable number of plural, different and separately identifiable carton types. Unsorted cartons are removed in successive layers from stacks thereof and transported in serial succession along a transport path. Sorting modules are disposed along the transport path, each including respectively associated routing and stacking devices individually predesignated to receive and stack a given, identifiable carton type. A system controller tracks the progress of each carton, simultaneously for plural cartons, along the transport path and when a match of the carton type with a predesignated stacking device is determined, actuates the associated routing device to route a carton of a matching type from the transport path and to the associated stacking device for stacking.

  • Patent number: 5197723
    Abstract: An automatic document feeding apparatus in which a plurality of documents are sequentially fed to an image exposure section. Before the completion of the exposure of a foregoing document, the feeding of a following document is started to place the document on a given position before the image exposure section and stopped thereon temporarily for stand-by. The position of the temporary stop of the following document can be varied in accordance with document size detecting signals from a document size detector or selected in such a manner that the distance between the trailing end of the foregoing document and the leading end of the following document becomes constant substantially irrespective of the size of the document.

  • Patent number: 5167406
    Abstract: Apparatus for automatically inverting workpieces of limp sheet material, such as fabric sheet material, including an endless primary conveyor having a forward-traveling reach for conveying workpieces in a forward direction, each workpiece having a leading edge and a trailing edge. A gripper engages a portion of the workpiece generally adjacent its leading edge as the workpiece travels on the primary conveyor and holds the leading edge portion stationary. The primary conveyor includes a series of flights spaced at intervals therealong with openings between the flights. The trailing edge of the workpiece and the adjacent trailing edge portion drop through an opening between a leading flight and a trailing flight after the gripper engages and holds stationary the leading edge portion. A pushing mechanism acts on the trailing edge portion of the workpiece for pushing the trailing edge portion forardly to invert the trailing edge portion as the leading edge portion is held stationary by the gripper.
