Abstract

A sheet or sheet stack handling system for performing at least one operation on successive sheets or stacks of sheets, and interface for the same, wherein the document handling system includes at least two modules selected from a group consisting of an elevator transfer station, a modular transfer station, a storage station, a transportation cart, and a modular processing station. When more than one modular processing station are coupled to form the document handling system, the system may be utilized to perform a series of operations on successive sheets or stacks of sheets. Alternately, the individual processing stations or a group of the processing stations may be utilized to perform only certain functions on the sheets. The modules each contain a plurality of parallel, spaced, elongated support surfaces that form a sheet support surface. The parallel, spaced, elongated support surfaces of the two modules are sized and disposed that they may intermesh to allow a transfer of sheet stacks between the modules when one set of parallel support surfaces is moved upward or downward relative to the other.

Description

FIELD OF THE INVENTION

[0001] The invention relates to a document processing system utilizing a transport system for passing sheet stacks between processing modules to provide optionally modular post-printer document processing. BACKGROUND OF THE INVENTION

[0002] In the sheet finishing industry, sheet stacks are transferred between processing equipment as various steps are performed on the stacks of sheets. This transfer is typically classified as “in-line” or “off-line,” and sometimes “near-line.”

[0003] “In-line” refers to two pieces of processing equipment having their sheet paths joined together such that individual sheets are passed from one system to the other sequentially and processed as such. While there are many examples of such “in-line” processing, one such prominent example is designed following the Xerox DFA (Digital Finishing Architecture) Standard. The DFA protocol spells out mechanical and software specifications for attaching finishing machinery to DFA compatible Xer...
