## Abstract

As set forth herein, a finisher module within an automated print system is described. A compiler delivery system receives and organizes one or more sheets in a predetermined configuration for delivery. A compiling belt system receives the one or more sheets from the compiler deliver system, locates the one or more sheets and transports the sheets concurrent to one or more finishing processes. A side tamper system moves alongside the compiling belt system to side tamp and register sheets in the cross process direction. A stapler/stitcher assembly moves alongside the compiling belt system to perform at least one of a stapling and a stitching operation as the one or more sheets are transported.

## Background
TECHNICAL FIELD
The presently disclosed embodiments are directed to a sheet finisher module system that operates concurrently with various finishing operations. In this manner, sheets can enter a compiling system consisting of multiple independently driven belts for sheet handling. However, it is to be appreciated that the present exemplary embodiments are also amenable to other like applications.
BACKGROUND
Automated production is utilized by today's printers to output large capacity jobs. Such production can require any number of operations including printing, collating, cutting, stapling, stitching, etc. to output a product that meets predefined specifications. Bottlenecks within the production operation can slow or stop output. These inefficiencies can occur due to substandard designs, mechanical failure, control malfunction and the like.
In one example, finishing systems that create stapled or stitched cut sheet sets can be slowed by a number of processes. For instance, final set registration, stitching/stapling, and set ejection operations can hamper output. Typically, although time is allocated to perform these functions, they can nevertheless extend beyond the time available prior to the arrival of the next incoming sheets or sets. Thus, finishing operations can create a negative impact on productivity and work flow (e.g., skip pitches).
Buffering techniques and/or multiple compiler stations have been employed to overcome such inefficiencies. However, buffering can limit the page sizes employed and/or the size of a print job. This problem becomes even more challenging, costly and prohibitive as the volume rate or sheets per minute requirements increase (especially at the production market volume values). Therefore, productivity is decreased especially with regard to small stapled/stitched sets.
Accordingly, there is a need for a system that overcomes inefficient print production output, especially at it relates to finishing processes.
BRIEF DESCRIPTION
In one aspect, a finisher module within an automated print system is described herein. A compiler delivery system receives and organizes one or more sheets in a predetermined configuration for delivery. A compiling belt system receives the one or more sheets from the compiler deliver system, locates the one or more sheets and transports the sheets concurrent to one or more finishing processes. A stapler/stitcher assembly moves alongside the compiling belt system to perform at least one of a stapling and a stitching operation as the one or more sheets are transported.
In another aspect, a finisher module is utilized within an automated print system. A compiler delivery system receives and organizes one or more sheets in a predetermined configuration for delivery. A compiling belt system receives the one or more sheets on a plurality of belts to catch the leading and trailing edge of the one or more sheets as they are received from the compiler deliver system, locates the one or more sheets and transports the sheets concurrent to one or more finishing processes. A stapler/stitcher assembly moves alongside the compiling belt system to perform at least one of a stapling and a stitching operation as the one or more sheets are transported.
In yet another aspect, a computer implemented method is employed to finish a set of one or more sheets in an automated print production process. The set of sheets is received and organized in a predetermined configuration for delivery. The set of sheets is located after they have been organized. The set of sheets is transported concurrent to at least one of stapling and stitching based at least in part upon the set location as it moves through the print production process.

DETAILED DESCRIPTION
FIG. 1 is a schematic diagram of a finisher module 100 within an automated print system. The module 100 includes a plurality of devices to perform various finishing processes related to the output of one or more print jobs. It is to be appreciated the automated print system can include any number of processing steps and/or operations such as printing, collating, duplex operations, binding, packaging, etc. For the sake of brevity, however, such steps will not be discussed in detail herein to focus solely on finishing and processes associated therewith. In addition, the term “sheet” as used herein, refers to any size, weight, color, thickness, etc. of sheets. A “set” as used herein refers to a plurality of sheets that are processed at substantially the same time.
Sheets are accepted by the finisher module 100 via a transport system 101, depicted as a line with a plurality of roller pairs 103 that advance sheets throughout the module 100. In this non-limiting example, the process direction of the module 100 is generally from left to right. That is, pages enter from the module from the left, undergo finishing and exit to the right to additional devices. Sheets can follow paths 102a, 102b or 102c, as required for each print job specification. Sheets following paths 102b and 102c can be registered as they pass through a registration system 104. A decurler 106 can mitigate curling as sheets exit the registration system 104. Alternatively, sheets that follow the path 102a can bypass the registration and decurling processes and proceed directly to a staple and/or stitching process.
Sheets can be transitioned via the transport system 101 to a compiling area 109, which includes a compiler delivery system transport 112 and a compiling belt system 116. While traveling to the compiling area 109, sheets can pass by one or more static eliminators 108 to mitigate deleterious effects of static associated with sheets in process. The compiler sheet delivery system 112 can deliver sheets at various process direction locations to the compiling belt system 116, which locates and transports sheets concurrent to one or more finishing processes.
This compiler delivery system 112 can utilize substantially any device for sheet transport such as a gripper, a clamp and/or a pinch type transport approach. The delivery system 112 is capable of carrying sheets over the compiling area 109 and dropping or releasing sheets at varying process direction locations and velocities as the compiling system 116 is stationary or is moved in the process direction. Other delivery approaches are contemplated wherein sheets are delivered to the compiling area 109 in the same fashion. In addition, a suppression system 114 (e.g., mechanical, pneumatic, etc.) can be used to assist in dropping sheets into the compiler area 109.
The compiling area 109 utilizes a belt concept that consists of tamping tabs or plates attached to belts. FIG. 2 illustrates the compiling system 116 within the compiling area 109 in greater detail. Trail edge tamping belts 202 and 204 and a lead edge tamping belt 206 are employed. The belts 202-206 are driven independently (in the same direction) to provide a lead edge set registration while moving and holding the set in the process direction. Each belt 202-206 can be geared and driven as appropriate to align a plurality of tabs that on each belt at a given point in time. In one example, the tab location is dependent upon the operation of one or more of the compiler delivery system 112, the side tamper assembly 118, and the stapler/stitcher 120. Tabs on the trail edge belts 202 and 204 can be employed to push the set in the process direction. In addition, baffles (not shown) can be placed between the belts 202-206 to better support the sheet and/or sets. Additional belts and configurations are contemplated to produce the same function stated above.
The compiling area 109 also has a side tamper assembly 118, which includes a pair of independently driven side edge tampers for cross process sheet and/or set registration. These tampers operate to cross process register the sheet and/or set while the tampers are stationary or moving with the sheets/set at the same velocity in the process direction at the same time. A number of approaches can be used to achieve this desired side tamper motion. As the side tampers are driven separately they can be used to create offset sets for the stacker 128, if desired. After each tamping operation, the tampers will reset backward relative to the process direction, if required, to repeat the operation with next sheet and/or set.
The compiling area 109 may not move in the process direction at all times during the compiling of sets. For example, the bulk of a larger set may be compiled using the belt tampers (of the compiling belt system 116), the side tampers (of the side tamper assembly 118) and/or the suppression system 114 while not moving in the process direction. Process direction compiling and work flow can commence during the compiling of the last few sheets or sheet of the set to sustain productivity requirements of the next sheet and/or set entering. Having the system perform in this fashion will help reduce the length of the finisher module 100.
The belt system 116 moves sheets in the process direction to allow a staple/stitcher 120 assembly to staple and/or stitch sheets while on the compiling belt system 116. A side-tamper assembly 118 includes a pair of two assemblies (e.g., one on each side) that move inward and outward to allow the staple/stitcher 120 to operate while concurrently moving in the process direction. Once the stitching and/or staple operation is complete, the sheets are ejected to a stacker 128. In this manner, the output of the finisher module is not compromised, as sheets are registered, stitched and ejected to the stacker 128 while maintaining motion of the set in the process direction to maintain full productivity. Moreover, sheets from subsequent sets entering the module 100 can begin finishing without negatively impacting productivity (e.g., delays, skip pitches, etc.).
The stapler/stitcher assembly 120 that enable stapling and/or stitching while moving with the set in the process direction at the same speed, in the process direction, and at the same time. Alternatively or in addition, the assembly 120 can be mounted to a driven carriage device (not shown) to allow for stapling/stitching at various widths (e.g., at inboard and outboard positions). Ejection of the set to the stacker 128 is enabled by either the extension of the existing belt system, a pass off to another belt transport system (capable of maintaining set integrity), and/or a gripper clamp mechanism device that pulls the set to the stacker 128.
The stacker 128 can have an optional capability to move in a process and/or a cross-process direction to create offset sets. Offsetting can also be accomplished by upstream devices (e.g., side tampers, registration systems, etc.) which has been demonstrated in other finisher devices. Other stacking options such as cart systems and the like can be integrated into such a stacking function. The module 100 can also be configured to have a separate optional paper paths for unstapled/unstitched sheets that takes them directly to the stacker (e.g., via a bypass transport 110) and can be registered and compiled with one or more additional registration devices such as disc, friction, and/or tamping devices to provide better quality stacking. Additional configured paper paths can be used to lead to a purge tray 122 or a bypass transport and exit path 124 which leads to another downstream device 130.
The module 100 can be configured to have a purge tray 122 to eject any sheet sets that do not meet one or more predetermined requirements. A registration system 104 can be added to pre-register incoming sheets to the compiler belt system 116, the 128 stacker, the purge tray 122 and/or the bypass transport 124. In addition, the registration system 104 can be used to offset sheets before entering some or all of the of the previously mentioned finisher areas (e.g., bypass, compiling, top tray, stacker).
FIG. 3 illustrates a computer implemented method 300 to transport sheets concurrent to one or more finishing operations. In this manner, sheets can be output from such an operation without having a negative impact. At reference numeral 302, the set of sheets is received and organized in a predetermined configuration for delivery. At 304, the set of sheets is located after they have been organized. At 306, the set of sheets is transported concurrent to at least one of stapling and stitching based at least in part upon the set location as it moves through the print production process.
