Description

PRINTER WITH DISCRETE SHEET LOAD ENHANCEMENT APPARATUS AND METHOD

CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation-in-part of U.S. patent application Serial No. 08/521,350 filed August 29, 1995 of Hill et al . entitled "Printing Assembly With Discrete Sheet Load Enhancement Apparatus and Method" which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

Field of the Invention:

This invention relates to printing assemblies in general and, in particular, to printing assemblies for printing card carrier forms used in card insertion systems.

Description of the related art including information disclosed under 37 C.F.R. 1.97 - 1.99:

Free standing single sheet printers which print selected material under control of a personal computer are widely known. These printers are provided with one or more trays for holding stacks of discrete, or single, blank sheets to be printed upon in position for pick- up by a transport mechanism which transports the single sheets through the printing apparatus, one sheet at a time. The transport mechanisms of these printers will not handle continuous forms which consist of sheets interconnected in a fan-folded stack or on a roll.

In the parent application referenced above, a conventional single sheet printer has its paper tray specially adapted to enable the printer to indirectly receive single sheets from a burster which separates single sheets from the fan-folded stack on interconnected sheets, feeds the separated single sheets, such as card carrier forms, into the tray.

Other printers are known which, in addition to the blank paper trays from which the transport system obtains blank sheets, have single sheet storage modules which hold a maximum supply of sheets that is several times the maximum capacity of the single sheet trays. Sheets are selectively transported from the discrete sheet storage module from the blank paper tray for printing. Again, however, the discrete sheet storage modules are adapted to hold only single sheets and the transport mechanism which draws sheets from the discrete sheet storage modules are only capable of transporting single sheets from the module to the printing apparatus.

Consequently, known single sheet general purpose paper printers have not been used in cooperation with card insertion systems to print card carrier forms which customarily are printed as continuous fan-folded forms connected in seriatim relationship. Known continuous carrier form printers print only on continuous forms which are subsequently separated into discrete individual forms. SUMMARY OF THE INVENTION

It is therefore a principal object of the present invention to adapt a single sheet printer for use with continuous interconnected sheets, such as continuous card carrier forms for use in an in-line printing card insertion system which mounts to, or inserts into, cards to printed carrier forms.

The object is achieved by providing a printing assembly having a printer, a single sheet storage module mounting location for releasable attachment of a single sheet transport mechanism for automatically transporting single sheets fed to a printer inlet by the single sheet storage module with a discrete sheet load enhancement apparatus, comprising a burster module for separating continuous printable stock received at a burster inlet into separate bursted sheets fed to a burster outlet and means for releasably attaching the burster module to the printer at the single sheet storage module mounting location with the burster outlet substantially aligned with the printer inlet to directly feed the separate bursted sheets to the printer transport mechanism.

Also, the object of the invention is obtained by provision of a method of printing, comprising the steps of (1) mounting a burster module to a printer assembly at a single sheet storage module mounting location m lieu of the single sheet storage module with a burster outlet substantially aligned with a printer inlet, (2) feeding continuous printable stock to a burster inlet burster module, (3) separating with the burster module the continuous printable stock received at the burster inlet into separate bursted sheets and (4) feeding the separate bursted sheets from the burster outlet to the printer inlet for transport to the printer for printing.

Moreover, obtainment of the object is achieved by a method of converting a conventional single sheet printer to function as part of an in-line card insertion system for inserting cards into matching carrier forms, comprising the steps of (1) mounting a carrier form burster module to the printer at a mounting location for a conventional single sheet feeder module otherwise releasably attached with the single sheet printer, said carrier form buster module adapted to separate individual carrier forms from a supply of continuous stock and feed the separate carrier forms to the printer and

(2) mounting a removable carrier form outlet guide especially adapted for guiding printed card carrier forms to a card inserter carrier form inlet at a mounting location for and in lieu of a conventional printer outlet tray otherwise releasably attached with the printer.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to Fig. 1, the preferred embodiment of the printing assembly 10 of the present invention has a discrete sheet load enhancement apparatus including a burster module 16 mounted at a single sheet storage module mounting location 11 of a single sheet printer 17. The burster module 16 interfaces with a discrete sheet transport mechanism 12 of the single sheet printer 17. The discrete sheet transport mechanism 12 transports individual sheets received at an inlet

13 to a discrete sheet printing mechanism 21. A pair of pinch rollers 20A and 20B are located at the inlet 13 as seen in

Figs. 2 and 3. The discrete sheet printing mechanism 21 prints selected information onto the sheets and passes the printed sheets to a printed sheet outlet 19. The burster module 16 receives at an inlet 23 interconnected fan-folded or rolled sheets from a continuous printable stock supply module

25, separates the continuous stock into single sheets 27 and feeds them to the transport mechanism inlet 13 one sheet at a time .

The discrete sheet transport mechanism 12 also has an inlet 15 at which it receives single sheets from a discrete sheet tray 14 which are passed to the discrete sheet printing mechanism 21. Advantageously, when the discrete sheet printing mechanism 21 is not used to print card carrier forms from the burster module, it is not disabled from printing on other single sheets from the discrete sheet tray 14.

As seen in Fig.2, in both a discrete sheet tray 14 and a single sheet storage module 16' are provided. The single sheet storage module is mounted to a slidable shelf 22 at the single sheet storage module mounting location 11 and contains a stack of discrete sheets 24. The individual sheets 24 are extracted from the single sheet storage module by means including a pair of pinch rollers 20A and 20B which feed the single sheets through the inlet 13 and into the discrete sheet transport mechanism 21. The printed sheets are produced at the outlet 19 and stacked on an outlet tray 29 releasably mounted at an outlet tray mounting location 31. Referring now to Fig. 3, the single sheet storage module

16' is replaced by the burster module 16 and releasably attached to the slidable shelf 22 at the single sheet storage module mounting location 11. A supply of continuous printable stock of fan-folded carrier forms 18 is mounted on the carrier form support shelf. The burster module 16 separates the blank continuous carrier forms which are received at the burster inlet 23 from the continuous printable stock 18 and are fed into the printer inlet 13 and thereby to the discrete sheet printing mechanism 21. A set of pinch rollers 26A and 26B of the burster module 16 feed the carrier forms 27 into engagement with the pinch rollers 20A and 20B. The outlet tray 29 of Fig. 2 is removed and a carrier form outlet guide

42 is mounted in its place and a movably mounted bar code reader 62 is mounted above the guide 42 to read bar codes on the printed carriers 27 as they emerge from the printing mechanism 21 at outlet 19.

Fig. 4 shows the slidable shelf 22 in an extended position for facilitating the removal of the discrete single sheet storage module 16' and mounting of the burster module 16 in its place. The slidable shelf 22 has alignment mounting pins 28A, 28B, 28C and 28D, as seen in Fig.5A, which correspond to mounting holes on the bottom of the discrete sheet storage module 16'. The burster module 16 has a base which is provided with corresponding alignment mounting holes

30A, 30B, 30C and 30D for releasably attaching the burster module 16 to the slidable shelf 22. Fig. 5B shows the burster module 16 mounted to the slidable shelf 22 with mounting pins

28A, 28B, 28C and 28D received through the mounting holes 30A,

30B, 30C and 30D, respectively, located in the bottom of the burster module housing. Referring now to Fig.βA, the PRIOR ART printer outlet 19 in which pinch rollers 36 and 38 feed carrier forms from the printing mechanism 21 into a PRIOR ART outlet tray 40 which receives and supports printed sheets. The outlet tray 40 is releasably mounted to the printer outlet 19 by means of two pairs of mounting hooks 48 which mount into corresponding mounting holes 50, seen m Fig. 6B .

Referring to Fig.βC, the carrier form outlet guide 42 for guiding printed carrier forms from the printer outlet 19 to an inserter inlet of a card inserter (not shown) is releasably mounted to the discrete sheet printing mechanism 21 m lieu of the outlet tray 29 by means of mounting hooks 52 which releasably fit into mounting holes 50.

The carrier outlet guide 42 has a horizontal floor 43 with a pair of open ends 44 and 46. Open end 44 is adjacent the printer outlet 19 for receipt of the printed carrier forms 27 while open end 46 interfaces with an inserter inlet for insertion into the inserter (not shown) . A pair of side walls 54 and 56 have inwardly turned members 58 and 60 for restraining the carrier forms 27 against vertical movement within the guide member 42. The bar code reader 62 is adjustably mounted adjacent the printer outlet 19 to read printed bar code information on the carriers as they emerge from the printer outlet 19. The bar code reader 62 is slideably mounted to a slot 64 for movably adjusting the bar code reader across at least a portion of the width of the outlet carrier guide 42.
