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 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.
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
