An apparatus for accumulating sheet material in a sheet handling system including a first conveyance, a second conveyance, an auxiliary conveyance and a processor to control the conveyances based upon a selected operating mode. The first conveyance receives singulated sheets and conveys the sheets to an accumulator station to produce completed collations. The second conveyance is operative to dispense completed collations from the accumulator station and, receives the completed collations from the first conveyance, in one operating mode, and from the auxiliary conveyance in another operating mode when the first conveyance is inoperative. The processor is responsive to a next collation signal, to control the conveyances based upon a selected one of the operating modes.

Accumulator for a sheet handling system

A vacuum roller assembly adapted to singulate a sheet from a stack of sheets. The vacuum roller assembly comprising a stationary inner plenum having a substantially linear plenum slot disposed in fluid communication with the vacuum source and a rotating vacuum roller disposed over the stationary inner plenum and rotating about a rotational axis. The vacuum roller includes a plurality of apertures disposed in fluid communication with the substantially linear plenum slot and about the periphery in at least one region of the roller. Furthermore, each of the apertures is substantially slot-shaped and defines a major axis. The major axis is off-axis with respect to the substantially liner plenum slot of the inner plenum to reduce audible noise levels produced by the rotating vacuum roller as air flows through each rotating aperture into the stationary linear plenum slot.

Vacuum roller assembly

A method for operating a sheet handling system including the steps of: determining a location of a next collation mark on select sheets of the stack of material, selecting an operating mode based upon the proximity of the next collation mark relative to a leading or trailing edge of each of the select sheets, processing the singulated sheets in a first operating mode when the next collation mark is proximal to the leading edge of each of the select sheets, and in a second operating mode, when the next collation mark is proximal to a trailing edge of each of the select sheets. Each of the select sheets is buffered to change the spatial relationship between each of the select sheet and each completed collation of sheets along the feed path. By selectively processing the sheets based upon the location of the next collation mark, the conveyance feed path is minimized.

System and method for minimizing the conveyance feed path of a sheet material handling system

An item handling system includes a transport system defining a transport plane, a printer assembly defining a printer plane, and a printer alignment system supporting the printer assembly. The printer alignment system includes a plurality of drive elements configured to move the printer assembly. A method of aligning a printer in the item handling system includes moving the printer assembly to a limit position of the printer alignment system distal from the transport system using the drive elements, moving the printer assembly to a limit position of the printer alignment system proximate to the transport system using the drive elements, and driving each of the drive elements at a respective predetermined level to place the printer plane in a substantially parallel orientation with respect to the transport plane.

Item handling system with printer alignment

A printing assembly includes a transport system configured to transport items on a transport path and a printer rotatably disposed on a support. The printer includes a plurality of printing elements disposed sequentially along the transport path. A method of calibrating the printing assembly includes aligning a first reference associated with the printer with a second reference associated with the support, transporting an item on the transport path, printing a pattern on the item using a first printing element and a second printing element, determining a correction value from the pattern, and rotating the printer relative to the support in an amount corresponding to the correction value to substantially align the printing elements with the transport path.
