Abstract
Media is transported to an imaging region using a vacuum feeder. A vacuum head is positioned onto the media and a vacuum is applied to the vacuum head to hold the media against the vacuum head. The vacuum head is then relocated to the imaging region carrying with it the media. In one embodiment, the vacuum head holds the media slightly above the surface of the imaging region. After the media is imaged, the vacuum head moves the media to an output region. In the output region the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the output region. In another embodiment, the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the imaging region. A second vacuum head is positioned in the imaging region onto the media and a vacuum is applied to the second vacuum head to hold the media against the second vacuum head. The second vacuum head is then relocated to the output region carrying with it the media. The second vacuum head moves the media to an output region. In the output region the vacuum is removed from the second vacuum head allowing the media to detach from the second vacuum head and remain in the output region.
Description




FIELD OF THE INVENTION




This invention relates in general to a feeder system and, more particularly, to a vacuum feeder system for imaging devices.




BACKGROUND OF THE INVENTION




In the current state of technology, document imaging has become commonplace. Documents are routinely, scanned, photocopied, and transmitted by facsimile machine. The use of these imaging processes is not limited to text documents. Photographs are now routinely imaged as well. As imaging of photographs has become more widespread, a desire has arisen to automate the imaging of multiple photographs.




Although it is possible to process multiple photographs using the same automated technology used for standard paper documents, there are drawbacks to doing so. The surface of a photograph is much more susceptible to marring than standard paper documents. Conventional rubber rollers used to process paper documents are capable of leaving skid and scratch marks across the surface of the photograph or crumpling the photograph in a paper jam.




Loss caused by damaged or destroyed photographs is oftentimes deeper than loss of an ordinary paper document. Photographs are often more valuable than ordinary paper documents. Some photographs are irreplaceable as the negative is unavailable or the photograph was produced from a method that did not result in a reusable negative.




It is for instances where photographs are valuable that the need is especially keen for a feeder system that will not harm the photographs. Additionally, some paper documents are particularly valuable or delicate. A feeder system that will accommodate these paper documents would also be desirable.




SUMMARY OF THE INVENTION




According to principles of the present invention, media is transported to an imaging region using a vacuum feeder. A vacuum head is positioned in an input region onto the media and a vacuum is applied to the vacuum head to hold the media against the vacuum head. The vacuum head is then relocated to the imaging region carrying with it the media.




According to further principles of the present invention in one embodiment, the vacuum head is nearly coextensive with the media and the vacuum head holds the media slightly above the surface of the imaging region. After the media is imaged, the vacuum head moves the media to an output region. In the output region the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the output region. The vacuum head then returns to the input region to retrieve another media.




According to further principles of the present invention in another embodiment, the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the imaging region. The vacuum head then returns to the input region to retrieve another media. Simultaneously, a second vacuum head is positioned in the imaging region onto the media and a vacuum is applied to the second vacuum head to hold the media against the second vacuum head. The second vacuum head is then relocated to the output region carrying with it the media. The second vacuum head then moves the media to an output region. In the output region the vacuum is removed from the second vacuum head allowing the media to detach from the second vacuum head and remain in the output region. The second vacuum head then returns to the imaging region to retrieve another media left in the imaging region by the first vacuum head.




Other objects, advantages, and capabilities of the present invention will become more apparent as the description proceeds.

is mounted to a shaft


4


. A support arm


6


is attached to beam


2


. A vacuum head


8


is supported by support arm


6


. Vacuum is supplied to vacuum head


8


by a vacuum system (not shown). The vacuum system may be any system for providing a controlled vacuum to vacuum head


8


.




In one embodiment vacuum head


8


is a flat, perforated surface. Alternatively, other configurations of vacuum head


8


are also acceptable. Vacuum head


8


may be any size. However, a size roughly coextensive with a standard photograph is most desirable for vacuum head


8


.




Vacuum head


8


is rotatable about a longitudinal axis


10


of shaft


4


and moveable parallel to longitudinal axis


10


. Optionally, vacuum head


8


is also moveable perpendicular to longitudinal axis


10


.




Vacuum head


8


may be made rotatable about longitudinal axis


10


using a variety of means. In one embodiment, shaft


4


is rotatable about longitudinal axis


10


. The rotation of shaft


4


about longitudinal axis


10


is transferred to beam


2


, support arm


6


, and vacuum head


8


causing vacuum head


8


to rotate about longitudinal axis


10


. In another embodiment, shaft


4


remains fixed relative to rotation about longitudinal axis


10


while beam


2


rotates about shaft


4


and longitudinal axis


10


. The rotation of beam


2


about longitudinal axis


10


is transferred to support arm


6


and vacuum head


8


.




Vacuum head


8


may also be made moveable parallel to longitudinal axis


10


using a variety of means. In one embodiment, shaft


4


is moveable parallel to longitudinal axis


10


. The movement of shaft


4


about longitudinal axis


10


is transferred to beam


2


, support arm


6


, and vacuum head


8


causing vacuum head


8


to move parallel to longitudinal axis


10


. In another embodiment, shaft


4


remains fixed relative to movement parallel to longitudinal axis


10


while beam


2


moves parallel to longitudinal axis


10


. The movement of beam


2


parallel to longitudinal axis


10


is transferred to support arm


6


and vacuum head


8


. In still another embodiment, both beam


2


and shaft


4


remain fixed relative to movement parallel to longitudinal axis


10


while support arm


6


moves parallel to longitudinal axis


10


. The movement of support arm


6


parallel to longitudinal axis


10


is transferred to vacuum head


8


. In a fourth embodiment, beam


2


, shaft


4


, and support arm


6


remain fixed relative to movement parallel to longitudinal axis


10


while vacuum head


8


moves parallel to longitudinal axis


10


.




For each movement of vacuum head


8


relative to longitudinal axis


10


, some mechanical device and control system is required for causing the movement. Suitable devices and control systems for each of the above described movements are well known in the art and do not require detailed description here as the present invention may be practiced using any suitable devices and control systems. Together the mechanical device and control system for causing the required movements will be referred to as a driver


19


.




Referring again to

FIGS. 1 and 2

, an input region


12


, an output region


14


, and an imaging region


16


are positioned about shaft


4


. In one embodiment, input region


12


, output region


14


, and imaging region


16


are arranged on one surface, such as the scanning surface of a scanner. Input region


12


is an area such as a bin, hopper, tray, or surface for storing media


18


before being imaged. Output region


14


is likewise a bin, hopper, tray, or surface for storing media


18


after being imaged. Media


18


is any media capable of being imaged. Examples of media


18


include photographs and paper documents. Imaging region


16


is a region for imaging media


18


. Examples of types of imaging regions


16


include a scanning surface for a scanner and an imaging surface for a photocopier or a facsimile machine including the immediately adjacent the scanning or imaging surface.





FIG. 3

illustrates a method for feeding media


18


to imaging region


16


. Vacuum head


8


is positioned


20


onto media


18


in input region


12


. A vacuum of sufficient volume for lifting media


18


is then applied


22


to vacuum head


8


. Vacuum head


8


is then conveyed


24


into imaging region


16


carrying media


18


to be imaged. Vacuum head


8


is conveyed


24


into imaging region


16


by rotating vacuum head


8


about longitudinal axis


10


of shaft


4


and moving vacuum head


8


parallel to longitudinal axis


10


as necessary to avoid obstructions in input region


12


and imaging region


16


. For example, if input region


12


includes an input bin having walls, moving vacuum head


8


parallel to longitudinal axis


10


may be necessary before rotating vacuum head


8


to imaging region


16


.




In one embodiment, vacuum head


8


positions media


18


onto an imaging or scanning surface of imaging region


16


. In another embodiment, vacuum head


8


positions media


18


so that a small gap exists between media


18


and an imaging or scanning surface of imaging region


16


. Allowing a small gap between media


18


and an imaging or scanning surface of imaging region


16


ensures that media


18


is not marred or damaged by contact with a surface of imaging region


16


.




In order to process additional media


18


, the media


18


held by vacuum head


8


must be discarded without covering imaging region


16


. Vacuum head


8


is conveyed


26


to output region


14


carrying media


18


. Vacuum head


8


is conveyed


26


into output region by rotating vacuum head


8


about longitudinal axis


10


of shaft


4


and moving vacuum head


8


parallel to longitudinal axis


10


as necessary to avoid obstructions in imaging region


16


and output region


14


. For example, if output region


14


includes an output bin having walls, moving vacuum head


8


parallel to longitudinal axis


10


may be necessary before rotating vacuum head


8


to output region


14


.




Upon arrival of media


18


into output region


14


, the vacuum applied to vacuum head


8


is removed


28


allowing media


18


to detach from vacuum head


8


. Media


18


remains in output region


14


as vacuum head


8


is returned to input region


12


for processing additional media


18


.





FIGS. 4 through 6

illustrate an alternate embodiment to the system described above and illustrated in

FIGS. 1 and 2

. A beam


30


is pivotally supported by two rocker arms


32


,


34


. Rocker arms


32


,


34


are each pivotally attached to mounts


36


,


38


. Beam


30


, rocker arms


32


,


34


and mounts


36


,


38


are linearly arranged so that beam


30


is moveable in a two-dimensional arcing motion pivoting on rocking arms


32


,


34


.




Affixed to beam


30


are two support arms


40


,


42


. Support arms


40


,


42


are attached to beam


30


at the distal ends of support arms


40


,


42


. Affixed to the proximal ends of support arms


40


,


42


are input and output vacuum heads


44


,


46


. Support arms


40


,


42


and input and output vacuum heads


44


,


46


are sized and located so that when beam


30


is at the endpoints of the arcing motion, vacuum heads


44


,


46


contact or closely approach an input region


48


, an imaging region


50


, and an output region


52


. Vacuum heads


44


,


46


are sized and located to either contact or closely approach the regions


48


,


50


,


52


depending on the desired proximity of media


18


to surfaces of the regions


48


,


50


,


52


.




As illustrated in

FIGS. 4 and 6

, input vacuum head


44


contacts or approaches input region


48


at one end of the arcing motion of beam


30


and imaging region


50


at the other end of the arcing motion of beam


30


. Likewise, output vacuum head


46


contacts or approaches imaging region


50


at one end of the arcing motion of beam


30


and output region


52


at the other end of the arcing motion of beam


30


.




Linked to beam


30


is a driver


54


for propelling beam


30


through the arcing motion. Driver


54


includes a rotating arm


56


having proximate and distal ends, a roller


58


rotatably affixed to the distal end of rotating arm


56


, a motor


60


having a rotating shaft


62


affixed to the proximate end of rotating arm


56


, and a roller retainer


64


affixed to beam


30


and having a slot


66


formed therein for capturing roller


58


.




As motor shaft


62


rotates about its longitudinal axis, rotating arm


56


rotates in a circular motion. As rotating arm


56


moves in a circular motion, roller


58


rides in slot


66


driving beam


30


in an arcing motion.

FIGS. 4 through 6

illustrate the position of beam


30


at 90? intervals of rotating arm


56


.





FIG. 5

illustrates beam


30


at the apex of the arcing motion. Beam


30


arrives at the apex of the arcing motion at two of the 90? intervals. Rotating arm


56


and roller


58


are shown as solid line for one of the intervals and as dashed lines for the other interval.




Illustrated in

FIGS. 7 and 8

are alternate embodiments of driver


54


for beam


30


.

FIG. 7

illustrates a single coupler design for driving beam


30


. The single coupler design is similar to the previously described embodiment of driver


54


except that instead of transferring the motion of rotating motor


60


to beam


30


through a roller


56


and roller retainer


66


, a coupler


68


interconnects rotating arm


56


and beam


30


. Coupler


68


is pivotally attached to both beam


30


and the distal end of rotating arm


56


.





FIG. 8

illustrates a double coupler design, a variation of the single coupler design described above and shown in FIG.


7


. The double coupler design includes a second coupler


70


interconnecting beam


30


and rotating arm


56


. Second coupler


70


is pivotally attached to both coupler and beam


30


. Also attached to the joint between coupler


68


and second coupler


70


is a third rocker arm


72


pivotally attached to a third mount


74


.




The single and double coupler designs for driver


54


illustrated in

FIGS. 7 and 8

are shown in one embodiment. Alternative embodiments for single and double coupler designs are well known in the art. For example, rotating motor


60


, coupler


68


, second coupler


70


, and rocker arm


72


may be in a nested configuration with beam


30


. The present invention encompasses all such variations in placement of rotating motor


60


coupler


68


, second coupler


70


, and rocker arm


72


. Other embodiments of driver


54


, not described here, are also possible and within the scope of the present invention.




Referring again to

FIG. 3

, a method is illustrating for transferring media


18


to imaging region


50


. Input vacuum head


44


is positioned


20


onto media


18


in input region


48


. A vacuum of sufficient volume for lifting media


18


is then applied


22


to input vacuum head


44


. Input vacuum head


44


is then conveyed


24


into imaging region


50


carrying media


18


to be imaged. Input vacuum head


44


is conveyed


24


into imaging region


16


by rocking beam


30


on rocking arms


32


,


34


.




In one embodiment, input vacuum head


44


positions media


18


onto an imaging or scanning surface of imaging region


50


. In another embodiment, input vacuum head


44


positions media


18


so that a small gap exists between media


18


and an imaging or scanning surface of imaging region


50


. Allowing a small gap between media


18


and an imaging or scanning surface of imaging region


50


ensures that media


18


is not marred or damaged by contact with a surface of imaging region


16


.




In order to process additional media


18


, the media


18


held by input vacuum head


44


must be discarded without covering imaging region


50


. The vacuum applied to input vacuum head


44


is removed


76


allowing media


18


to detach from input vacuum head


44


. Media


18


remains in imaging region


50


as input vacuum head


44


is returned to input region


48


for processing additional media


18


.




In order to remove media


18


from imaging region


50


, output vacuum head


46


is positioned


78


onto media


18


. A vacuum of sufficient volume for lifting media


18


is then applied


80


to output vacuum head


46


. Output vacuum head


46


is then conveyed


82


into output region


52


carrying media


18


. Output vacuum head


46


is conveyed


52


into output region


16


by rocking beam


30


on rocking arms


32


,


34


.




Upon arrival of media


18


into output region


52


, the vacuum applied to output vacuum head


46


is removed


84


allowing media


18


to detach from output vacuum head


46


. Media


18


remains in output region


52


as output vacuum head


46


is returned to imaging region


50


for removing additional media


18


from imaging region


50


.





FIG. 9

illustrates one embodiment of a vacuum system


86


for supplying vacuum to the vacuum heads


8


,


44


,


46


of the present invention. For ease of reference, vacuum system


86


will be described and illustrated only for input vacuum head


44


. Vacuum systems


86


for other vacuum heads


8


,


46


are similar.




Vacuum system


86


includes a bellows


88


in fluid communication with input vacuum head


44


and exhaust valve


90


. Bellows


88


includes an elastomeric boot


92


and a compression spring


94


. Exhaust valve


90


includes a toggle activator switch


96


.




Bellows


88


is mechanically compressed when input vacuum head


44


is positioned onto media


18


in input region


48


. Air is forced out of open exhaust valve


90


by the compression. The same action that compresses bellows


88


also engages toggle activator switch


96


when bellows


88


is fully compressed. Engaging toggle activator switch


96


closes exhaust valve


90


. As input vacuum head


44


is removed from input region


48


, compression spring


94


acts to expand elastomeric boot


92


. The expansion of elastomeric boot


92


generates the vacuum necessary to hold media


18


against input vacuum head


44


while input vacuum head


44


travels to imaging region


50


.




Bellows


88


is again mechanically compressed when input vacuum head


44


is positioned forced onto imaging region


50


by beam


30


. The same action that forces vacuum head


44


onto imaging region


50


also engages toggle activator switch


96


. Engaging toggle activator switch


96


opens exhaust valve


90


allowing an inrush of air to fill the vacuum in input vacuum head


44


and releasing media


18


. Input vacuum head


44


then returns to input region


48


leaving media


18


in imaging region


50


.




In an alternate embodiment, vacuum system


86


includes at least one vacuum motor (not shown) in fluid communication with the vacuum heads


8


,


44


,


46


for supplying vacuum to the vacuum heads


8


,


44


,


46


. In this embodiment, a control system (not shown) is required for controlling the vacuum applied to vacuum heads


8


,


44


,


46


. In one embodiment of the control system, the control system controls the vacuum applied to vacuum heads


8


,


44


,


46


by determining the position of vacuum heads


8


,


44




46


and activating and deactivating the vacuum at appropriate locations. The position of vacuum heads


8


,


44


,


46


may be discovered in a variety of ways all of which are known in the art. For example, sensors (not shown) may be placed so that the sensors are contacted as beam


30


moves into specific locations.




In an alternative embodiment of the control system, sensors are positioned to determine whether media


18


has been picked up by vacuum heads


8


,


44


,


46


. The sensors may either be vacuum sensors or proximity sensors. Vacuum sensors are placed in the fluid stream between the vacuum motor and vacuum head


8


,


44


,


46


. When the sensors perceive a vacuum, media


18


is being held against vacuum head


8


,


44


,


46


. When no vacuum is perceived by the vacuum sensors, media


18


is not being held by vacuum head


8


,


44


,


46


.




Proximity sensor are placed either to sense the proximity of media


18


or the proximity of input region


48


, imaging region


50


, and output region


52


. When the proximity is sensed, the control system assumes media


18


is being held against vacuum head


8


,


44


,


46


. When no proximity is perceived by the proximity sensors, the control system assumes media


18


is not being held by vacuum head


8


,


44


,


46


.




A means (not shown) for releasing the vacuum is also required when using a vacuum motor. The means for releasing the vacuum may be a valve activate by a sensor, or a switch for the shutting off the vacuum motor also activated by a sensor.




Other embodiments of vacuum system


86


are possible and within the scope of the present invention.




When retrieving a photograph from a stack of photograph, the photographs tend to cling together. Photographs are one type of media


18


contemplated by the present invention.

FIGS. 10 and 11

illustrate, in cross-section, an obstruction


98


for ensuring only one media


18


is picked up from input region


12


,


48


. As media


18


is removed from input region


12


,


48


, media


18


encounters obstruction


98


causing media


18


to flex. Flexing media


18


ensures only one media is picked up from input region


12


,


48


.




Other embodiments of obstruction


98


are possible and within the scope of the present invention. Although obstruction


98


is desirable, it is not required for the proper functioning of the present invention.





FIG. 12

illustrates, an aligning trough


100


for aligning media in imaging region


16


,


50


. Aligning trough


100


aligns media


18


as it enters imaging region


16


,


50


. Other embodiments of aligning trough


100


are possible and within the scope of the present invention. Although aligning trough


100


is desirable, it is not required for the proper functioning of the present invention.




Photographs tend to curl slightly. When the media


18


to be imaged is a photograph or other media


18


which tends to curl, it is desirable to have some means for flattening media


18


. One means for flatting media


18


for imaging is to apply a vacuum to substantially the entire surface of one side of media


18


. This may be easily accomplished when vacuum head


8


,


44


,


46


is a flat surface roughly the same size as media


18


. When vacuum head


8


,


44


,


46


is not a flat surface roughly the same size as media


18


, another means for flattening must be used.




Illustrated in

FIGS. 13 and 14

is a media cover


102


for flattening media


18


for imaging. For ease of reference, media cover


102


will be described and illustrated only for input vacuum head


44


. Media covers


102


for other vacuum heads


8


,


46


are similar.




Media cover


102


includes a flat surface roughly coextensive in size with a standard photograph. A hole


104


should be defined within the approximate center of media cover


102


for allowing support arm


40


and vacuum head


44


to pass through. Media cover


102


is attached to support arm


40


and Vacuum head


44


is spring loaded against support arm


40


. The spring loaded forces vacuum head through hole


104


during times when no pressure is applied to vacuum head


44


, such as when vacuum head


44


is traveling between input region


48


and imaging region


50


. When vacuum head


44


encounters pressure, such as when media


18


is pressed against a surface of imaging region
