Description
The increasing use of devices such as dollar bill changers which
accept individual pieces of paper currency and which, after the
currency has been validated, retain the piece of paper currency and
dispense either change or merchandise, has created a need for a
simple and reliable device for accepting the paper currency from
the validating apparatus and for stacking the currency in a compact
and aligned manner. Such a device must be capable of automatic
operation and must be capable of providing reliable operation over
prolonged periods of time.
It is the primary object of the present invention to provide a
stacking device which is capable of receiving individual paper
currency pieces and of stacking successive pieces in a uniform and
aligned manner.
It is also an object of the present invention to provide a paper
currency stacking device which may device which may be used in
conjunction with a currency validating device or the like.
A further object of the invention is a provision of a paper
currency stacking device which is of simple and inexpensive
construction and which is capable of providing reliable
operation.
The above and other objects of the invention which will become
apparent in the following detailed description are achieved by
providing a paper currency stacking device which consists,
essentially, of an open-topped box-like enclosure which has a pair
of horizontal support plates secured to the enclosure internally
and adjacent the open upper end thereof, a floating plate below the
support plates and spring biased upwardly, and a plunger which
moves downwardly through the space between the support plates. The
device is designed to receive a dollar bill or other unit of
currency from a currency validating apparatus or other equipment.
The individual piece of currency is supported at its opposite edges
on the support plates. Downward movement of the plunger forces the
currency piece through the opening between the support plates and
on to the floating plate. Subsequent upward movement of the plunger
results in the piece of currency being held between the support
plates and the floating plate.
For a more complete understanding of the invention and of the
objects and advantages thereof reference should be had to the
following specification and the accompanying drawings wherein there
is shown a preferred embodiment of the invention.

The currency stacking device, designated generally by the reference
numeral 10, includes a box-like enclosure having opposite end walls
12, a front wall 14, and rear wall 16 and a bottom wall 18. The
lower portion of the rear wall 16 is hinged, as indicated at 22, to
provide a door 20. Preferably, the length and width of the interior
of the enclosure are only slightly greater than the length and
width of the paper currency. It will be noted that the top of the
enclosure is open. A pair of horizontal support plates 24 are
provided near the upper end of the enclosure. These plates do not
extend the entire length of the enclosure but provide an opening 26
midway between the end walls 12. Below the support plates 24 there
is provided a floating plate 28 which has projecting tabs 30 at its
opposite ends which extend through the slots 32 in the end walls
12. Suitable means such as coil springs 34 are attached to the tabs
30 and to pins 36 near the upper end of the end walls 12. The
springs 34 serve to hold the floating plate 38 against the
underside of the fixed support plates 24. Obviously, other
arrangements for biasing the plate 28 upwardly such as compression
springs between the plate 28 and the floor 18 may be used in place
of the springs 34.
Associated with the enclosure and aligned with the opening 26 is a
plunger 38 which may be operated by any suitable means, such as the
solenoid 40. Mounted on the lower end of the plunger 38 is a
rectangular plate 39 which is slightly smaller than the opening 26
between the support plates 24. As shown in FIG. 3, the plunger 38
and plate 39 are normally held sufficiently far above the support
plates 24 so as not to interfer with the movement of a piece of
currency onto the support plates.
The operating sequence of the stacker is illustrated in FIGS. 3
through 5. In FIG. 3, a single piece of paper currency 42 has been
received within the enclosure. The opposite ends 42a of the bill
are supported by the fixed support plates 24. When the solenoid 40
is actuated, as shown in FIG. 4, the plunger 38 moves downwardly
through the opening 26 carrying the bill 42 below the fixed support
plates 24. It will be noted that the ends 42a of the bill are bent
upwardly in a wing-like manner by the support plates 24. When the
plunger 38 is withdrawn, as shown in FIG. 5, the spring 34 moves
the floating plate 28 upwardly. The end portions 42a of the bill 42
are now caught by the undersides of the support plates 24 and the
floating plate 28. Obviously, when a second bill is pushed through
the opening 26 by the plunger 38, it will be stacked on top of the
previously stacked bill. In this manner a stack of bills is
accumulated between the support plates 24 and the floating plate
28. The pressure applied by the springs 34 assures that the bills
will be completely stacked.
As shown in FIG. 1, the bill stacker 10 may be used in conjunction
with a currency validating device 50. Typically, such a device 50
has a bill receiving tray 52 on which a single piece of paper
currency is positioned in a specified orientation. The validating
device includes a housing 54 which encloses the validating
equipment. When the bill has been validated it is discharged from
the rear of the housing 54 on to a sloping tray or chute 56 which
directs the bill into the open upper end of the stacker 10.
Obviously, the rear portions of the validating device 50 and the
entire bill stacking assembly 10 will be housed in a suitable
enclosure to prevent pilferage. Since all of the bills must be
supplied to the validating equipment 50 in a particular
orientation, all of the bills supplied from the chute 56 to the
stacker 10 will also be oriented in a uniform manner. As a result,
the stack of bills which accumulates within the stacker 10 will all
be uniformly aligned.
The door 20 permits access to the stack of bills which has
accumulated within the stacker 10. A suitable latch, not shown, may
be provided to normally hold the door 20 in its closed position.
Depending on the mounted arrangement of the stacker 10, the door
location may be varied, for example to the front wall 14.
Any suitable means may be used to control the operation of the
plunger 38. For example, when the stacker 10 is used with the
currency validating equipment 50, the plunger 38 may be operated by
actuating means 40 which is controlled by the validating device so
that the actuating means operates every time a bill is discharged
from the tray 56.
Obviously, as is shown in FIGS. 6 and 7 the horizontal support
plates 24a may extend along the front and rear walls 14a and 16a,
respectively, rather than along the end walls. In this embodiment,
the plates 24a extend less than the entire width of the enclosure
to provide an opening 26a midway between the front and rear walls.
A vertically movable plunger 38a which has a rectangular plate 39a
at its lower end is normally positioned above the enclosure and is
provided with suitable actuating means (not shown) for moving the
plunger downwardly so that the plate 39a moves through the opening
26a and pushes the floating plate 38a downwardly. As in the
previously described embodiment, the floating plate 38a is biased
upwardly against the underside of the horizontal plates 24a.
The operation of this embodiment is identical to that described
above with the exception that the bills or notes received in the
enclosure are supported along their upper and lower edges by the
support plates 24a rather than along their ends. Downward movement
of the plunger plate 39a causes the bill to move through the slot
26a with the edges of the bill bent upwardly in a wing-like
fashion. Upon subsequent upward movement of the plunger plate 39,
the edges of the bill are pressed between the floating plate 38a
and the undersides of the horizontal support plates 24a.
FIGS. 8 through 11 illustrate a third embodiment of the invention.
The currency stacker, designated generally by the numeral 60 is
shown in conjunction with a currency validating device 62 which has
a discharge tray 64. The validating device 62 operates in the
conventional manner, receiving a single piece of paper currency,
testing the currency for authenticity and if the currency is
validated, discharging it onto the tray 64. The discharge tray 64
may be somewhat inclined, as shown, so that the piece of currency
slides downwardly toward the end 65 of the tray 64. As an alternate
arrangement, a driven roller may be provided to positively move the
piece of currency to the edge 65 of the tray 64.
Mounted adjacent the end 65 of the tray 64 are a pair of support
plates 66 and 68 which are also inclined downwardly. The plates 66
and 68 are separated by an opening 70 so that only the end portions
of the piece of currency are supported by these plates. Beneath the
support plates 66 and 68 is a bottom plate 72 which is supported by
arms 74, the free ends of which are carried on pivot pins 76
mounted either on the housing of the validating device 62 or on a
suitable separate framework. Biasing means such as springs 78 are
provided in conjunction with the arms 74 to normally bias the
bottom plate 72 upwardly against the undersides of the support
plates 66 and 68. A pair of upwardly projecting curved blade-like
stops are provided on the bottom plate 72 at the ends of the
support plates 66 and 68. These stops 80 serve to prevent the piece
of currency from sliding off the ends of the support plates 66 and
68. Also, pivotally connected to the pins 76 is a U-shaped frame
member 82. The center portion 84 of this frame 82 is provided with
a plate 86 which, when the frame 82 is in the position shown in
FIGS. 8 and 9, is located above the opening 70 and slightly above
the upper surface of the support plates 66 and 68. The end of the
plate 86 toward the discharge tray 64 is curved upwardly, as
indicated at 88, so that a piece of currency moving downwardly from
the tray 64 onto the support plates 66 and 68 will move freely
under the plate 86. Suitable means such as springs 90 are provided
to normally bias the frame 82 in its upper position, that is the
position shown in FIGS. 8 and 9. Suitable stops, not shown, may be
provided to limit this upward movement. A motor 92 drives a gear
train 94 which in turn drives a curved rack or gear segment 96
which rotates on the pin 76 and is connected to the U-shaped frame
82. As can be seen from FIG. 10, when the motor 92 is operated the
frame 82 is caused to pivot downwardly with the plate 86 passing
through the opening 70 between the support plates 66 and 68 to move
the bottom plate 72 downwardly.
The operation of this embodiment is basically the same as that
described in connection with the above embodiments. When a piece of
currency has been accepted by the validator 62 it moves onto the
discharge tray 64 and subsequently onto the support plates 66 and
68, being retained by the stops 80. As previously pointed out, the
support plates 66 and 68 engage only the opposite ends of the piece
of currency. The motor 92 is now actuated to cause the U-shaped
frame 82 to pivot downwardly about the pins 76. The plate 86 thus
moves downwardly pushing the piece of currency through the opening
70 and onto the bottom plate 72. The piece of currency will assume
a wing-like configuration as the plate 86 moves downwardly. When
the frame 82 and the plate 86 have completed their downward
movement, the springs 90 move the frame 82 and plate 86 upwardly.
The bottom plates 72 also move upwardly at the same time due to the
action of the springs 78. The ends of the piece of currency are now
restrained by the undersides of support plates 66 and 68 and as
upward movement of the bottom plate 72 continues the piece of
currency is pressed between the undersides of these support plates
and the bottom plate 72. The device is now ready to accept another
piece of currency and the same operation will be repeated with a
new piece of currency being stacked between the underside of the
support plates 66 and 68 and the previously stacked piece of
currency. As additional pieces of currency are added, a stack of
currency will be accumulated between the bottom plate 72 and the
support plates 66 and 68.
Various arrangements may be used to control the operation of the
motor 92. For example, the motor 92 may be controlled by the
validating device 62 so that the motor operates after each
acceptance and authentication of a piece of currency.
Alternatively, the currency stacker 60 may be provided with a
switch which is actuated by the presence of a piece of currency on
the support plates 66 and 68 to control the motor 92.
It should now be apparent that there has been provided a paper
currency stacking device which fulfills the objectives set out
above. It should also be apparent that changes and modifications
may be made in and to the described embodiments. Reference should
therefore be had to the appended claims in determining the true
scope of the invention.
