Definitions

  • This invention pertains generally to an apparatus and method for handling lazy-portrait printed documents (printing across the continuous paper web to produce paired portrait orientated pages or in "lazy-portrait narrow-end to narrow-end” formatting (LPEE)) so as to generate acceptably oriented pages that are then processed and grouped into pre-designated document sets with continuously numbered pages.
  • lazy-portrait printed documents printing across the continuous paper web to produce paired portrait orientated pages or in "lazy-portrait narrow-end to narrow-end” formatting (LPEE)
  • a hinged divided or bifurcated transfer cart that permits a desired reorientation of a portion of the lazy-portrait printed documents to facilitate further processing in a correctly ordered page-sequence for document sets, wherein when LPEE head-to-head or bottom-to-bottom paired pages are printed, one half of the printed pairs must be flipped for generation of a sequential page count in each final assembled document set.
  • FIG. 2 depicts a pair of traditionally formatted pages that are then separated/cut- apart and simply stacked on top of one another, as shown in FIG. 3, to produce a correctly page-sequences document set.
  • printers that function in this manner are the IBM InfoPrint 4000 and Oce VahoStream 7000.
  • a continuous stream of traditionally printed sheets (such as the ones shown in FIG. 1 and/or FIG. 2) is printed and then moves into a slitter that separates the single steam into two streams of continuous sheets that then enter a cutter and collator for further processing to generate correctly page-sequenced document sets (as illustrated in FIG. 3 for two cut sheets).
  • paper is printed in a lazy-portrait narrow-end to narrow-end (LPEE) format (as seen in FIGS.
  • LEE lazy-portrait narrow-end to narrow-end
  • lazy-portrait also known in the industry as "rotated landscape” when a printer merely uses a traditional printer head alignment spanning the entire page to print a rotated image
  • lazy-portrait is defined as a portrait oriented page that is generated by printing the page from one wide edge to the other wide edge (side to side) and not from narrow edge or end to narrow edge or end (top to bottom or visa-versa), as is done in every other currently existing printing system.
  • the critically issue with the subject invention is that when a pair of head-to-head or bottom-to-bottom pages are printed on a continuous stream of paper, the single stream of paper with the paired images must then be separated/slitted into two separate streams of paper with one stream being flipped over to correctly orient the final pages when cut and stacked into a document set (as seen in FIG. 6 for a pair of LPEE printed sheets).
  • the current subject invention presents a system and method for accomplishing this sheet flipping process by flipping one entire stream of post-slitted sheets via utilization of a hinged and bifurcated LPEE document transfer cart.
  • FIGS. 7A, 7B, and 7C An example of a currently manufactured cart for handling two up portrait paper is manufactured by Beste Bunch Co., Inc.
  • This cart (very much a traditional dolly for moving heavy items from one location to another) is designed to receive paper coming out of a folder attached to a continuous form printer like an Oce VarioStream 7000.
  • the existing prior art process is depicted clearly in FIGS. 7A, 7B, and 7C, In FIG. 7A a traditional dolly/cart is pivoted into a horizontal position on a support rack (on the far left of FIG. 7A) to accept incoming fan-folded documents.
  • Such fan-folded documents are shown stacked on the dolly/cart (with a bottom support plate removed to accept incoming documents), extending along the delivery tract, and coming out of the printer (on the far right of FIG. 7A).
  • the bottom support plate is temporarily removed, the fan-folded documents loaded, and the bottom support plate reinstalled when the documents are loaded.
  • the bottom support plate is secured back into a normal vertical load-supporting position and the entire dolly/cart pivoted on the support rack into the vertical transfer position with the wheels contacting the floor (plainly illustrated in FIG. 7B). As seen in FIG.
  • the loaded traditional dolly/cart is then backed away from the support rack and moved to any desired location for transfer of the fan-folded documents.
  • the entire intact (non-slitted) stream of two-up portrait printed sheets is moved as a continuous fan-folded unit.
  • the prior dolly/cart system must simply handle a stack of two-up portrait printed paper without any special handling or stack manipulation required, since the needed document orientation automatically results from the way the printed paper exits the printer.
  • the paper is then pulled off of the prior art dolly/cart-stack in one direction into a page cutter, either first on-first off the cart, or first on-last off the cart, depending on how the cart was loaded with the paper.
  • Patent No.: 6,994,005 (an apparatus for slitting, merging, and cutting a continuous paper web) describes an in-line turn-bar that is positioned after slitting and prior to merging the two streams, but this invention only positionally moves one slit lane of paper to overlap with another slit lane of paper, without turning over the obverse to reverse orientation (or face to back orientation).
  • This patent differs from the subject invention in that, since there is no need, suggestion, or teaching to so, it does not turn over the paper orientation.
  • Patent No.: 6,595,465 (a turn-bar assembly for redirecting a continuous paper web) describes turning a single web of paper to reorient the travel direction and, in addition, to optionally flip the paper web from obverse to reverse (face up to face down) image orientation in this reoriented travel direction.
  • This patent differs from the subject invention in that it reorients the paper direction, which is not associated with the manner in which a turn-bar is employed in the subject invention.
  • An object of the present invention is to provide a paper handling system that orients lazy-portrait narrow-end to narrow-end format printed sheets into correctly page-sequenced document sets.
  • Another object of the present invention is to furnish a paper handling apparatus and method that flips one of two paired lazy-portrait narrow-end to narrow-end format printed sheets to generate printed sheets that have correctly sequenced pages that are assembled into desired document sets.
  • a further object of the present invention is to supply a paper handling apparatus and method that produces correctly page-sequenced document sets from a continuous web of lazy-portrait narrow-end to narrow-end (LPEE) format printed sheets by slitting a continuous stream of LPEE paired sheets into two streams, flipping one of the two streams, cutting each stream, and collating the cut sheets into correctly page-sequenced document sets.
  • LPEE lazy-portrait narrow-end to narrow-end
  • Still another object of the present invention is to disclose paper handling apparatus and method that produces correctly page-sequenced document sets from a continuous web of lazy-portrait narrow-end to narrow-end (LPEE) format printed sheets by slitting a continuous stream of LPEE paired sheets into two streams, loading each stream of slitted LPEE sheets into side-by-side receiving trays in the subject hinged and bifurcated cart, flipping one of the two streams by swinging the receiving trays into a back-to-back orientation, drawing off in the same direction from each of the receiving trays the two continuous streams of sheets, thereby flipping the orientation of one stream relative to the other, cutting each stream, and collating the cut sheets into correctly page-sequenced document sets.
  • LPEE lazy-portrait narrow-end to narrow-end
  • Yet a further object of the present invention is to describe a document transfer cart comprising two hinged-together document receiving trays, a removable bottom support plate assembly for each tray, a top delivery roller for each tray, a hinge connecting the two trays to each another, support rack pivot means, handle means, and transport means.
  • Still yet another object of the present invention is to relate a document transfer cart, and method of use, comprising two side-by-side and hinged- together document receiving trays, for each tray a removable bottom support plate assembly having hinge rotational support means, a top delivery roller for each tray, a central hinge connecting the two trays to each another, support rack pivot means, handle means, and transport means.

  • LPEE lazy-portrait narrow-end to narrow-end
  • LPEE format when a pair of head-to-head or bottom-to-bottom pages are printed on a continuous stream of paper, the single stream of paper with the paired images must then be separated/slitted into two separate streams of paper with one stream being flipped over to correctly orient the final pages (to produce the correct page- sequences) when cut and stacked into a document set.
  • the current subject invention presents an apparatus and method for accomplishing this sheet flipping process for one of the two paired document streams.
  • the printed continuous web is split into two continuous streams of sheets by a slitter.
  • One of the two continuous streams of sheets is then flipped by first loading both streams into the subject hinged and bifurcated cart.
  • the subject cart comprises two hinged-together document receiving trays, a removable bottom support plate assembly for each tray (only one of which has a hinge rotational support means), a top delivery roller for each tray, a hinge connecting the two trays to each another, support rack pivot means, handle means, and transport means.
  • FIG. 1 is a depiction representing the PRIOR ART, wherein four total sheets are shown with paired/duplexed-document pages printed side-by-side, with all side-by-side pages oriented in traditional portrait-parallel fashion to one another.
  • FIG. 2 is a depiction representing the PRIOR ART, wherein two total sheets (still physically connected together) are shown with paired/duplexed- document pages printed side-by-side, with all side-by-side pages oriented in traditional portrait-parallel fashion to one another.

  • FIG. 4 illustrates the subject invention's formatting technique that produces lazy-portrait documents wherein four total printed sheets are depicted in a duplexed lazy-portrait head-to-head page orientation and printed on a continuous web in two printing lanes (simplexed printing jobs are only printed on one side of a sheet, thereby making assembly of a multi-page document more simplistic than with the duplexed embodiment which requires a sheet flipping process step for one of paired sheets relative to the other sheet that is the main focus of the subject invention).
  • FIG. 5 shows the subject invention's formatting technique that produces lazy-portrait documents wherein a pair of printed sheets is depicted in a duplexed lazy-portrait head-to-head page orientation and printed on a continuous web in two printing lanes.
  • FIG. 6 shows the subject invention's ability to flip one of the paired sheets seen in FIG. 5 to produce correctly page-sequenced sheets (during normal operation, an entire stream of sheets are flipped and matched with its appropriate mate from the original pairing).

  • FIG. 6 shows the subject invention's ability to flip one of the paired sheets seen in FIG. 5 to produce correctly page-sequenced sheets (during normal operation, an entire stream of sheets are flipped and matched with its appropriate mate from the original pairing).
  • FIG. 7A shows an example of how the PRIOR ART utilized a traditional transfer cart (a standard hand cart or dolly), in a tilted or horizontal position at a receiving station (support rack in front of the printing producing the fan- folded documents) with its removable bottom plate temporarily removed for loading the printed documents as they exit a printer in a fan-folded stream.
  • FIG. 7B shows the traditional PRIOR ART transfer cart that has received the fan-folded documents (the removable bottom plate is now replaced into a document-support position) and is now lowered from the receiving horizontal position to contact the transfer cart's wheels with the ground for future movement.

  • FIGS. 4-6 and FIGS. 8-15 For illustrative purposes the present invention is embodied in the apparatus generally shown in FIGS. 4-6 and FIGS. 8-15. It will be appreciated that the apparatus may vary as to configuration and as to details of the parts, and that the method of its use may vary as to the specific steps and sequence, without departing from the basic concepts as disclosed herein.
  • the hinged and bifurcated cart system invented for handling the lazy- portrait narrow-end to narrow-end (LPEE) format printed stacks of documents is extremely innovative in that it receives the stream of document pages (actually two paired and fan-folded streams of LPEE printed sheets that are split by a slitter apparatus) from a folder either N to 1 or 1 to N document sequencing and then passes on the sheets to further post-printing equipment (normally a cutter/collator) in a dramatically different page orientation that is possible from a traditional cart that delivers a single stream of fan-folded sheets to a cutter/collator.
  • LPEE lazy- portrait narrow-end to narrow-end
  • the side-by-side and hinged-to-one-another receiving trays of the subject cart pivot together into an approximately horizontal receiving position on a receiving rack/frame (as seen in FIG. 14) for receiving or loading the split/slitted stream of fan-folded sheets that comes out of the slitter.
  • the paper is stacked on the subject cart in a configuration similar to traditional two-up portrait printing, however, the critical and novel feature of the subject invention is that the printed pages are slit into two discrete fan-folded stacks that are then placed into the approximately horizontally positioned receiving tray areas of the subject invention (again, see FIG 14).
  • the subject cart is constructed to permit the side-by-side receiving trays to be pivoted into the approximately horizontal position for receiving the two folded streams of document fan-folded sheets.
  • the receiving trays of the subject cart are then tipped/pivoted into an approximately upright orientation for transportation and handling.
  • the two loaded receiving trays of the subject cart are then rotated 180° along a central hinge mechanism to reorient the alignment of the LPEE printed pages to one another.
  • FIGS. 1 1 -13 and 15 illustrate the results of the 180° rotation. This rotation results in flipping one steam of fan- folded documents, relative to the other stream, as the sheets are drawn off and into the cutter/collator.
  • each page orientation of the original LPEE printed pages is now properly aligned so that the head and foot of each page is aligned in the same orientation and in proper page- sequential order.
  • the obverse and reverse (face up and face down) image orientation generated by the LPEE format printing technique such that one half of the original stack is printed in reverse image orientation (face down), whereas the other half of the stack is printed in obverse (face up) image orientation. Since one stack is rotated 180 degrees relative to the other, the final step to reorient the printed sheets is to pull the stream of sheets from both stacks (in the open cart orientation as seen in FIG.
  • the subject bifurcated cart (seen in its closed state to receive documents) has two hinged-to-each-other page- receiving halves or trays 10 and 20 which are designed to function as side-by- side page receiving means when being loaded with the two streams of LPEE printed documents, one stream in each tray 10 and 20 (post slitting that generated the two side-by-side streams of LPEE documents).
  • Each receiving tray 10 and 20 has a back panel 1 1 and 21 , opposing side panels 12, 13, 22, and 23, a bottom support assembly 14 and 24, a back support member 30 and 40, a transport wheel 31 and 41 attached to each back support member 30 and 40, respectively, a cart support rack/frame pivot bar 50 and 60 (for tilting into the document loading position on the supporting rack/frame), a paper path roller 70 and 80, and a cart handle 71 and 81 .
  • the removable bottom support assemblies 14 and 24 usually differ slightly from one another.
  • Assembly 14 comprises a removable bottom support plate 90.
  • the bottom support plate 90 is releasibly mounted on support arms 91 and 92 that project out from the bottom of the tray 10 and held in place by suitable means such as the shown clips 94 (a pair on each side of the bottom support plate 90) and slots 95 (a pair in each arm 91 and 92).
  • the bottom support plate 90 may be removed by simply sliding the plate clips 94 out of the arm slots 95.
  • the bottom plate 90 is remounted by sliding the plate clips 94 back into the arm slots 95.
  • Bottom support assembly 14 has a hinge rotational support means fastened to the lower side of the bottom support plate 90.
  • the rotational support means usually comprises one or more casters/wheels 96 that aids in swiveling one tray 10 from the other tray 20 when the cart 5 is opened along the central hinge 1 10 to deliver the two separate streams of fan- folded sheets, one stream flipped from the printed orientation.
  • Bottom support assembly 24 comprises a removable bottom support plate 100.
  • the bottom support plate 100 is releasibly mounted on support arms 101 and 102 that project out from the bottom of the tray 20 and held in place by suitable means such as the shown clips 94 (a pair on each side of the bottom support plate 100) and slots 95 (a pair in each arm 101 and 102).
  • the bottom support plate 100 may be removed by simply sliding the plate clips 94 out of the arm slots 95.
  • the bottom plate 100 is remounted by sliding the plate clips 94 back into the arm slots 95.
  • the bottom support assembly 24 does not have a hinge rotational support means as seen in bottom support assembly 14 since only one tray 10 needs to rotate away while the other tray 20 remains relatively stationary on the floor (both halves may have hinge rotational support means and this is contemplated to be within the realm of this disclosure).
  • a central hinge 1 10 is provided for a pivotal connection between the two trays 10 and 20.
  • the cart 5 When the cart 5 is ready to deliver the two separate fan- folded streams of documents the cart 5 is opened along the central hinge 1 10 that connects the two trays 10 and 20 to one another.
  • tray 20 is stationary on the floor while tray 10 rotates away from tray 20, supported by the casters/wheels 96, and into the opened document delivery configuration seen in FIGS. 1 1 -13 and 15.
  • FIGS. 8-19 and 14 all show the subject cart 5 in its closed or document receiving state (FIG. 14 clearly shows the cart 5 pivoted into a horizontal position to receive the incoming two streams of fan- folded documents from the slitter) while FIGS. 1 1 -13 and 15 all show the subject cart 5 in its opened or document delivering state.
  • FIG. 15 Stressing FIG. 15, the beauty of the subject cart 5 is clearly seen.
  • the subject cart 5 is loaded with the two separate steams of fan-folded documents that are printed in LPEE formatting, the subject cart is merely moved to any desired location for cutting and collating. Once at the desired location the cart 5 is simply opened into its delivery configuration, the document streams from the two separate document stacks are drawn in the same direction over their delivery rollers 70 and 80 and pulled into the cutter/collator. The 180° opening of the cart 5 flips the one stack's orientation when the sheets are drawn from the same side over rollers 70 and 80.
  • a suitable control and verification means are associated with the subject method.
  • Those means implement the subject method by generating printed pages from input data, tracking printed pages through the slitter, subject cart flipping process, cutter, and collator, and verifying the process is functioning properly and that correctly page-sequenced document sets are created.
  • Appropriately designed computer programs control the LPEE printing process, necessary paper transport processes, the slitting device, the cutting equipment, the collation of correctly page-sequenced document sets, and any additional post collation processes.
  • One benefit of the subject invention is that a single paper stack handling cart (bifurcated at a hinged region), with an overall structural similarity (before operation of the hinged movement) to existing stack paper handling carts, utilize similar equipment on the printers, so no additional structural changes or investment are needed on the printers.
  • the paper path from the subject cart is a smooth path with no tortuous bends, thereby eliminating paper breakage to the cutter.
  • this system allows printing LPEE with existing printing and folding equipment and cutting and inserting on an inserter that has been minimally modified to accommodate the LPEE paper sheet and image orientation.
