Disclosed in the embodiment herein is a flexible integration system for receiving printed sheets from plural printers and selectably directing those printed sheets to plural sheet outputs areas for plural outputs to selectably different sheet processing systems, such as different finishers, with a sheet position sensing system and a dual-axis flexible sheet transporting system (which may be integrated in a planer table device). The disclosed sheet transporting system of the embodiment provides selectable sheet translation movement and/or rotation from selected ones of said plural sheet input areas to selected ones of said plural sheet outputs areas so as to provide selectable sheet feeding from selected printers to selected sheet processing systems.
A large area of multiple spaced sheet driving elements (providing variable angle sheet driving directions) and sensors may be provided in an intelligent, adaptive, scaleable, closed-loop paper path plane, which can simultaneously enter, exit, move and re-position multiple sheets thereon. Any sheet entering at any position can be moved to any other location in the paper path plane. With a variable velocity as well as variable angle sheet movement system in the disclosed embodiment, the outputs of slower PPM printers with slower sheet velocities can be combined into a single or plural sheet output streams of higher velocities and PPM rates. Continuous feedback sensing of sheet positions can be provided.
In accordance with aspects of the exemplary embodiment a multifunction printed sheets interface system and method of directing printed sheets are provided. In one aspect, the multifunction printed sheets interface system includes plural sheet input areas, plural sheet outputs areas, a sheet position sensing system, and a sheet transporting system. The sheet transporting system includes independently operable sheet transports and provides selectable sheet translation to selectably transport sheets from selected ones of the plural sheet input areas to selected ones of the plural sheet outputs areas. The sheet transports provide variable angle driving for selectable sheet rotation and translation of selected sheets.
In another aspect, a system includes a plurality of printers, a plurality of sheet processing systems, and a multifunction printed sheets interface system. The interface system includes a plurality of sheet input areas which receive printed sheets from the plurality of printers, a plurality of sheet outputs areas which provide plural outputs to different ones of the sheet processing systems, a sheet position sensing system, and a sheet transporting system. The sheet transporting system provides selectable sheet translation to selectably transport sheets from selected ones of the plural sheet input areas to selected ones of the plural sheet outputs areas so as to provide selectable sheet feeding from selected printers to selected sheet processing systems.
In another aspect, the method includes printing sheets on a plurality of printers and feeding the printed sheets from the plurality of printers to a plurality of respective input areas of a printed sheets interface system. The printed sheets are transported from the input areas to selected ones of a plurality of output areas of the printed sheets interface system with a plurality of sheet transports. A position of the printed sheets is sensed during transporting.
With the disclosed embodiment, the inputs and outputs of plural lower speed printers, different paper feeders and different output devices can be more readily and flexibly combined into collated print jobs with the printing speed of a much higher speed printer.
Although not limited thereto, incorporated by reference, where appropriate, by way of background, are the following references variously relating to what have been variously called “tandem engine” printers, “parallel” printers, or “cluster printing” (in which an electronic print job may be split up for distributed higher productivity printing by different printers, such as separate printing of the color and monochrome pages), “output merger” or “interposer” systems, etc. For example, Xerox Corp. U.S. Pat. No. 5,568,246 issued Oct. 22, 1996; Canon Corp. U.S. Pat. No. 4,587,532; Xerox Corp. U.S. Pat. No. 5,570,172 to Acquaviva; T/R Systems Barry et al U.S. Pat. No. 5,596,416; Xerox Corp. U.S. Pat. No. 5,995,721 to Rourke et al; Canon Corp. Fujino U.S. Pat. No. 4,579,446; a 1991 “Xerox Disclosure Journal” publication of November-December 1991, Vol. 16, No. 6, pp. 381-383 by Paul F. Morgan; and a Xerox Aug. 3, 2001 “TAX” publication product announcement entitled “Cluster Printing Solution Announced.” One example of a Xerox Corp. sheet “interposer” patent is U.S. Pat. No. 5,389,969.
Also noted are commonly assigned Xerox Corp. U.S. Pat. No. 6,554,276, by Jackson, et al, and U.S. Pat. No. 6,607,320, by Bobrow, et al, with sheet positioners and sheet “reverters,” respectively issued on Apr. 29, 2003 and Aug. 19, 2003, both of which were filed on Mar. 30, 2001 and published on Oct. 3, 2002.
By way of an example of a variable vertical level, rather than horizontal, “universal” input and output sheet path interface connection from a single printer to a single finisher, there is Xerox Corp. U.S. Pat. No. 5,326,093. This patent is noted and incorporated as demonstrating that additional possible optional input and/or output feature here, since various different printers and third party finishers may have different sheet output levels and sheet input levels.
The exemplary multiple selectively directional (variable drive angle) sheet transports disclosed in this embodiment for two-axis sheet movement and/or rotation are the “SNIPS” systems already described an shown in Xerox Corp. U.S. Pat. No. 6,059,284 issued May 9, 2000. These SNIPS systems may thus be schematically represented herein, and need not be described in detail herein. Also noted as to somewhat similar transport systems are an MIT Draper Lab U.S. Pat. No. 4,836,119 and a Hewlett-Packard U.S. Pat. No. 6,241,242 issued Jun. 5, 2001. As disclosed in said U.S. Pat. No. 6,059,284, each SNIPS sheet drive has a spherical frictional drive ball engaging any overlying sheet, which drive ball is rotated in any desired direction and speed by two orthogonal servo-driven rollers drivingly engaging the opposite side of the ball. Overlying idler balls, pneumatic pressure or suction, or other known paper feeding normal force systems may be added, if desired, to hold the sheets down against the drive balls in addition to sheet gravity.
Various large area multiple optical sensor arrays, such as with LED's and multiple pixel photocells, with SELFOC or other collimating lenses, may be used, and are also known in the art, and in the imaging bar art, and need not be described in detail herein. Particularly noted and incorporated by reference herein is U.S. Pat. No. 6,476,376 B1 filed Jan. 16, 2002 and issued Nov. 5, 2002 by David K. Biegelsen, Bryan Preas, Lars Erik Swartz and Warren B. Jackson. FIGS. 9 and 11 thereof are noted in particular. Various large area two-dimensional optical object orientation and/or recognition sensors, such as overhead video cameras and associated software, are also known.
A specific feature of the specific embodiments disclosed herein is to provide a multifunction printed sheets interface system, comprising plural sheet input areas for receiving printed sheets from plural printers, plural sheet outputs areas for plural outputs to different sheet processing systems, a sheet position sensing system, and a sheet transporting system, said sheet transporting system providing selectable sheet translation to selectably transport sheets from selected ones of said plural sheet input areas to selected ones of said plural sheet outputs areas so as to provide selectable sheet feeding from selected printers to selected sheet processing systems.
Further specific features disclosed in the embodiment herein, individually or in combination, include those wherein said sheet transporting system additionally provides selectable sheet rotation of selected sheets; and/or wherein said sheet transporting system additionally provides selectable sheet merging in a selected sheet sequence of sheets from said plural printers to a selected said sheet processing system; and/or wherein said sheet transporting system comprises a multiplicity of spaced and independently operable variable-sheet-feeding-direction sheet transports; and/or wherein said sheet transporting system is a generally planar sheet feeding table larger than the dimensions of any sheet to be fed thereon for simultaneous plural sheet variable transport thereon; and/or wherein said sheet transporting system has a large planar area with a multiplicity: of spaced apart independently operable variable sheet feeding direction and sheet velocity sheet transports, said large planar area being substantially larger than the dimensions of any sheet to be fed thereon to allow simultaneous plural sheet variable transport thereon by said multiplicity of spaced apart independently operable variable sheet feeding direction and sheet velocity sheet transports, said sheets being sensed thereon by said sheet position sensing system, and said sheet position sensing system controlling said multiplicity of spaced apart independently operable variable sheet feeding direction and sheet velocity sheet transports.
The disclosed system may be operated and controlled by appropriate operation of conventional control systems. It is well known and preferable to program and execute imaging, printing, paper handling, and other control functions and logic with software instructions for conventional or general purpose microprocessors, as taught by numerous prior patents and commercial products. Such programming or software may, of course, vary depending on the particular functions, software type, and microprocessor or other computer system utilized, but will be available to, or readily programmable without undue experimentation from, functional descriptions, such as those provided herein, and/or prior knowledge of functions which are conventional, together with general knowledge in the software or computer arts. Alternatively, the disclosed control system or method may be implemented partially or fully in hardware, using standard logic circuits or single chip VLSI designs.
The term “reproduction apparatus” or “printer” as used herein broadly encompasses various printers, copiers or multifunction machines or systems, xerographic or otherwise, unless otherwise defined in a claim. The term “sheet” herein refers to a usually flimsy physical sheet of paper, plastic, or other suitable physical print media substrate for images, whether precut or web fed. A “copy sheet” may be abbreviated as a “copy” or called a “hardcopy.” A “print job” is normally a set of related sheets, usually one or more collated copy sets copied from a set of original document sheets or electronic document page images, from a particular user, or otherwise related.
A “finisher,” as broadly used herein, is any post-printing accessory device such as an inverter, sorter, mailbox, inserter, interposer, folder, stapler, binder, over-printer, envelope stuffer, postage machine, etc.
As to specific components of the subject apparatus or methods, or alternatives therefor, it will be appreciated that, as is normally the case, some such components are known per se in other apparatus or applications, which may be additionally or alternatively used herein, including those from art cited herein. For example, it will be appreciated by respective engineers and others that many of the particular component mountings, component actuations, or component drive systems illustrated herein are merely exemplary, and that the same novel motions and functions can be provided by many other known or readily available alternatives.
