Abstract: A print interface system includes a printer integrated in combination with a sheet handling system such as a mailpiece inserter. The print interface system facilitates the handling of sheet material in various operating modes, including conventional printing, duplex printing, and mailpiece creation modes. The system includes an interface module having upper and lower housing segments defining first and second feed paths. A first feed path directs sheet material to a stacking surface of the upper housing segment and a second feed path directs sheet material to a downstream module of the sheet handling device. A repositionable diverter bifurcates the path exiting the printer to direct sheet material to one of the two feed paths. Furthermore, the upper housing segment is pivotally mounted to the lower housing segment to provide internal access to one of the first and second feed paths.

Abstract: A print interface system including a printer integrated in combination with a sheet handling system such as a mailpiece inserter. The print interface system facilitates the handling of sheet material in various operating modes, including conventional printing, duplex printing, and mailpiece creation modes. The system includes a printer having multiple feed paths for printing on opposing face surfaces of a sheet material. One of the feed paths directs sheet material to a staging tray and another feed path directs sheet material to a downstream module of the sheet handling system. The system further includes a positionable diverter for directing sheet material to one of the feed paths and a sheet sensor for determining when a sheet of material has been directed along the feed path leading to the output tray. A controller is operative to alternately reposition the diverter from one of two positions.

Abstract: In a mail inserter having an envelope movement mechanism to move an envelope into an insertion station and a feeder to move a pack of insert material into an insertion position so that the insert material can be inserted into the envelope, a linear array of optical sensing elements is used to determine the position of one edge of the insert material and another linear array of optical sensing elements is used to determine the position of one edge of the receiving envelope in order to make sure that there is sufficient end clearance between the insert material and the receiving envelope. A stepper motor is used to adjust the envelope position, if the end clearance is outside a predetermined range.

Abstract: A method and a system are disclosed for adaptively controlling a stepper motor to produce a required torque output based on selection information provided by a sensor or a user/user interface which, in combination with a selector, selects a torque-related value. The selection information provided to the selector for selecting the stepper motor torque-related value may be, for example, the size or thickness of material being handled or the number of accumulated sheets for processing. The torque-related value is predetermined through experimentation and loaded into a lookup table stored in the memory of a motion control system board. The selected torque-related value is provided to a stepper motor driver which supplies the appropriate drive signal(s) to the stepper motor.

Abstract: Discrete means of setting a feeder to process a wide range of media, i.e., sheets, slips, envelopes, booklets and hand collated documents, etc. as well as providing a method of utilizing the feeder for manual feed operation. The foregoing is accomplished by a friction-clutch retard feeder equipped with one or more friction clutches. When a selection lever is moved to a position 1, a primary clutch engages the separator roller with a resistive torque T1. The selection lever configures the mechanism such that the separator roller rotation is resisted entirely by the torque of the primary clutch. When the selection lever is moved to a position 2, the ground of the primary clutch is removed, and the rotation of the separator roll is coupled through a gear ratio to a secondary clutch. The selection of the gear ratio and the value of the secondary clutch allows the separation mechanism to be resisted by a second torque, T2, which can be lower than T1.

Abstract: A method and apparatus for folding inserts by inverting the insert sheet after the first fold is made and reintroducing the folded insert sheet into a first buckle chute from the opposite end. The second fold is then made in a second buckle chute which results in either a bottom address or a middle address appearing on the folded insert in a manner that the address will appear through the window of the envelope.

Abstract: A system and method for accumulation of media invention includes a series of upper and lower transport belts for feeding media seriatim along a path of travel. An accumulator pocket is positioned between the upper and lower drive belts along the path of travel. An upper and a lower accumulator ramp is positioned adjacent the accumulator pocket are moveable between a first position and a second position. The first accumulator ramp position is such that the lower ramp is positioned to engage media moved seriatim along the path of travel to guide the media to form a forward accumulation of media in the accumulator pocket. The upper accumulator ramp second position is such that the upper accumulator ramp is positioned to engage media moved seriatim along the path of travel to guide the media to form a reverse accumulation of media in the accumulator pocket.

Abstract: A thru-beam sensor is positioned such that the beam passes through the crease line of the envelope when the envelope is parked in the insertion area. As the envelope enters the insertion area, the through beam sensor is set to current level A. The sensor is used to accurately position the envelope based on the passing of the lead edge. Once the envelope is in position, the current in the thru-beam emitter pair is raised until the envelope is no longer obstructing the line of sight of the sensor. From this state, the insert or plurality of inserts that are entering the accumulator can be detected, as the presence of the inserts will inhibit light transmission between the emitter and receiver. Using the sensor system proposed here, the inserts trailing edge can be detected at the crease line of the envelope.

A stepper motor is used to adjust the envelope position, if the end clearance is outside a predetermined range.

Abstract: A transport module for deskewing and accumulating sheets of insert materials before the sheets are inserted into an envelope for mailing. Retractable gates are used to stop the sheets as they are separately moved into the transport module by a plurality of endless belts. Idlers are used to apply normal forces on the belts at various locations to provide traction between the sheet and the belts for moving the sheet forward. If a sheet is skewed when it enters the transport module, one corner on the leading edge of the sheet encounters one of the side gates and the advancing sheet can align itself by an angular motion using the contact point as center of rotation. As such, the leading edge is registered against the retractable gates at both sides of the leading edge. The transport module can also be used as a conveyor without the accumulation function.

Abstract: An accumulator system and method for collating a plurality of media items wherein the media items enter in seriatim at an media item entry point and become at least partially overlapped with each other at a media item exit point. A media item transport path connects the media item entry point and the media item exit point. A moveable member is mounted along the media item transport path between the entry point and the exit point. The moveable member forms part of a pocket into which media items are moved to create a collation of media items. The moveable member is moveable to change the size of the pocket. A protective member may be mounted to the moveable member and positioned to protect the trailing edge of media items in the pocket from the leading edge of media items to thereafter be moved into the pocket. The media item may be aligned in the collation position when moving the protective member to a media item trailing edge protective position.
