Abstract
A note stacker for a currency validator includes a stationary punch and movable rails having slots therein adapted for receiving the currency tendered thereto. The stationary punch comprises a top plate surface of the housing maintaining drive motors and gears of the stacker itself. The top plate is curved to accommodate the natural deflection of the bill as it is being stacked, and is provided with a durable frictional material along lateral edges thereof to prevent the bill from sliding or otherwise moving upon the surface of the curved plate. A leading edge of the curved plate is provided with serrations or teeth which, in conjunction with a shutter fixed to the movable rails, serves to defeat strings or other retrieval elements.
Description
TECHNICAL FIELD
The invention herein resides in the art of currency validators or acceptors. More particularly, the invention relates to stackers for currency validators, such stackers being adapted to receive, stack and maintain currency or notes determined to be valid. More particularly, the invention relates to stackers for currency validators which are space efficient and capable of accommodating notes or currency of various widths.
BACKGROUND OF THE INVENTION
Currency validators or note acceptors are now widely know and used. Oftentimes, such currency validators are free standing, providing the opportunity to change paper currency into coins. Other currency validators are incorporated into vending machines and the like to aid in effecting transactions. There, a note or paper currency may be tendered for effecting a purchase. The currency validator determines the validity of the tendered paper and, if determined to be invalid, rejects the same and denies the transaction. Otherwise, if determined to be valid, the paper currency is escrowed until the transaction is completed and then the currency is transported to a stacker where it is maintained with other genuine currency or notes. Those skilled in the art will appreciate that the total system of a note acceptor includes a validation portion where paper tendered as currency is validated and/or rejected, and a stacker, which receives and stacks the valid currency so received.
Stackers require a certain amount of space. A first portion of the space is required for actually maintaining the bills or paper currency actually received as authentic. Other space is required for movement of the punch which typically characterizes such stackers. Those skilled in the art will appreciate that the punch of a stacker may be actuated by scissors, a screw, or any other of various means. Typically, the operative mechanism of a stacker employs on the order of 1.5 inches of dead space to effectuate the stacking motion. This is 1.5 inches of space unavailable for receiving and stacking currency and, in systems where space is at a premium, greatly reduces the number of bills that may be accommodated by the stacker. Such a situation increases the frequency of service calls to the currency validator and, accordingly, reduces the efficiency of its operation.
It is also known in the art that the physical size of paper currency often varies from country to country and among the various denominations in any particular country. Accordingly, the inlet slot, note path and receiving rails of note acceptors must typically be able to accommodate all widths of notes that might be tendered thereto. In order to accommodate such various widths of notes, the inlet slot of some currency validators is typically justified or registered at one edge thereof, requiring that the currency enter the validator flush with that side or edge. As a consequence, the punch of the associated stacker does not symmetrically engage the note, allowing the note to “walk” across the punch, often resulting in a skewed note being maintained within the stack. The result may often be a denigration of the integrity of the stack which may ultimately jam or otherwise incapacitate further operation of the currency validator.
In light of the foregoing, there is a need in the art for a compact stacker adapted to receive and stack notes or currency of various widths.
DISCLOSURE OF INVENTION
In view of the above, it is a first aspect of the invention to provide a stacker for currency validators which is of a compact nature.
Another aspect of the invention is the provision of a stacker for currency validators which is capable of accommodating notes of various widths.
Still a further aspect of the invention is the provision of a stacker for currency validators which employs a stationary “punch.”
Yet a further aspect of the invention is the provision of a stacker for currency validators in which note receiving rails move through a stationary “punch.”
Yet another aspect of the invention is the provision of a stacker for currency validators in which the stationary punch has an arched or radiused top surface for deflecting notes into the stack.
Still a further aspect of the invention is the provision of a stacker for currency validators in which the stationary punch is provided with frictional gripping edges along each side of the arched top surface for engaging and securing the note as it is added to the stack.
A still further aspect of the invention is the provision of a stacker for currency validators which is reliable and durable, easy to use, and conducive to manufacture with state of the art elements and techniques.
The foregoing and other aspects of the invention which will become apparent as the detailed description proceeds are achieved by a note stacker for a currency validator, comprising: first and second oppositely positioned rails, said rails being spaced apart to define a gap, said rails being reciprocatingly movable together and being adapted to receive a note therebetween; a fixed plate in registration with said gap on a first side of said note when said note is received between said rails; and a movable plate biased toward said rails from a second side of said note when said note is received between said rails.
Other aspects of the invention which will become apparent herein are attained by a note stacker for a currency validator, comprising: a fixed housing; a pair of rails having a gap therebetween, said pair of rails being reciprocatingly movable over said fixed housing to alternatingly receive a top portion of said fixed housing within said gap and release said top portion from said gap.
BRIEF DESCRIPTION OF THE DRAWINGS
For a complete understanding of the objects, techniques and structure of the invention, reference should be made to the following detailed description and accompanying drawings wherein:
FIG. 1
is a schematic diagram of the note stacker made in accordance with the invention;
FIG. 2
is an illustrative view of a portion of the stacker of the invention, showing certain parts thereof removed to effect an appropriate view;
FIG. 3
is the illustrative view of
FIG. 2
, showing the stationary punch and transport wheels present;
FIG. 4
is the illustrative view of
FIG. 3
with the shutter and transition teeth present; and
FIG. 5
illustrates the stacker of the invention with the control housing and both movable rails present.
BEST MODE FOR CARRYING OUT THE INVENTION
Referring now to the drawings and more particularly to
FIG. 1
, it can be seen that a note stacker made in accordance with the invention is designated generally by the numeral
10
. The note stacker
10
is maintained within a housing
12
having a top
14
, base
16
, and sides
18
,
20
. Those skilled in the art will appreciate that the housing
12
may be of any suitable nature. Maintained within the housing
12
is a control housing
22
which, as will become apparent later herein, contains motors, drive wheels, gears and the like to effectuate the desired stacking of currency or bills received.
The control housing
22
is characterized by an arched or radiused top plate
24
. While the radius of the top plate
24
may vary, it is contemplated to be on the order of 3.5-4.5 inches, and most preferably 4 inches. As will become apparent herein, the arched top plate
24
of the control housing
22
serves as a stationary punch for the note stacker
10
. In that regard, the radius or arch of the plate
24
is such as to maintain the normal curvature of contact with the currency or bills being stacked by the stacker
10
during the stacking operation. Further, to assure that the bills maintain fixed contact with the plate
24
during the stacking operation, and to further assure that they do not walk or slide therefrom, inserts
26
of durable frictional material such as RTV or the like may be positioned longitudinally along the edges of the top plate
24
, as shown. This frictional material engages the note or currency during the stacking operation and, in combination with the arched or curved surface thereof, assures that the note or currency does not walk or slide during the stacking operation. Accordingly, all bills or notes are consistently and uniformly stacked.
With continued reference to
FIG. 1
, it can be seen that the control housing
22
is positioned within a gap
28
defined between vertically movable side rails
30
,
32
. It is desired that the control housing
22
and top plate
24
be centrally positioned within the movable gap
28
to effectuate the “punching” or stacking of notes as will become apparent later herein. Moreover, it is preferred that the rail
30
have a minor slot
34
extending longitudinally therealong while the rail
32
have a major slot
36
so extending. As shown, the major slot
36
extends into the rail
28
a greater depth than the slot
34
into the rail
30
. As shown, a note or paper currency
38
is received by the slots
34
,
36
as placed therein by transport rollers to be discussed later herein. The notes
38
are justified against the wall of the slot
34
, with the opposite edge of the note
38
being received within the slot
36
, which is of sufficient depth as to accommodate any width of note intended to be received by the stacker
10
. Accordingly, the resultant stack
40
of notes of various sizes is uniform along the left side of the stack as shown in
FIG. 1
, but is staggered on the right side, as a result of the various widths of notes received and maintained thereby. A stacking plate
42
, generally of the size of the largest bill to be received by the stacker
10
, is biased by a spring
44
interposed between the top
14
of the housing
12
and the plate
42
to maintain the bill stack
40
against the top surface of the movable rails
30
,
32
. The biasing by the spring
44
allows for the stack
40
to be maintained as the rails
30
,
32
move during a stacking operation.
With reference now to
FIGS. 2-5
, it can be seen that the rail
30
is vertically movable upon a track
46
secured to wall
20
. The track
46
may be of any suitable nature. It will also be appreciated that a similar track is provided upon the wall
18
in association with the rail
32
for such vertical movement. The rails
30
,
32
are provided with support blocks
48
,
50
(
FIGS. 2 and 5
) having forward and rearward slots
52
therein for receipt of pins
54
to be driven by drive wheels
56
,
58
to effect the reciprocating upward and downward movement thereof. The support blocks
48
,
50
are interconnected by a cross member
60
to maintain appropriate space and unity of operation. Such simultaneous movement of rails
30
,
32
is further effected by the simultaneous driving of such wheels by a common motor
62
through appropriate fore and aft gear drives
64
. Of course, the motor
66
is preferably a reversible motor, and may be a servo or stepper motor, as desired.
As best shown in
FIGS. 3 and 4
, a second reversible motor
66
is provided with a gear drive
68
to effectuate rotation of transport rollers
70
passing through appropriate slots
74
in arched top plate
24
. As will be appreciated by those skilled in the art, the transport rollers
70
move a bill or piece of currency authenticated by the validator through the slots
34
,
36
of the rails
30
,
32
. The drive or transport rollers
70
may work against idler rollers (not shown) in somewhat common fashion to effectuate the necessary bite to achieve the desired transport.
As further shown in
FIG. 3
the arched top plate
24
is characterized by formed edges
72
to receive durable frictional material inserts
26
, shown in FIG.
1
. Any suitable material such as RTV or the like may be placed into the machined edge portions
72
for the desired purpose. Further, the front or leading edge of the plate
24
may be characterized by teeth or serrations
76
to assist in defeating “stringing” mechanisms by those who might seek to retrieve their currency once it has been validated and accepted. The teeth or serrations
76
operate in conjunction with a shutter or gate
80
as shown in
FIG. 4
to defeat the attachment of any “stringing” type element that might otherwise be attached to the currency being validated. In a preferred embodiment of the invention, the shutter or gate
80
is connected to and movable with the rails
30
,
32
at front edges thereof to pass in proximity to the teeth or serrations
76
of the top plate
24
to define any retrieval path across the teeth or serrations
76
during the stacking operation, thus assuring that any stringing mechanism is torn or broken if retrieval is attempted.
Also shown in
FIG. 4
are teeth or serrations
78
which are provided as a part of the housing
12
to interface with the validator or acceptor with which the stacker
10
is employed. The teeth or serrations
78
mate with corresponding teeth or serrations on the validator or acceptor to assure a smooth transition therebetween.
In use, a note or bill is transported from the validating portion of a note acceptor to the stacker
10
and into the slots
34
,
36
of the side rails
30
,
32
. The motor
66
operates the transport rollers
70
to position the note so received immediately above the arched top plate
24
of the control housing
22
. The bill is justified against the inside edge of the slot
34
, with the slot
36
accommodating the opposite edge of the bill or note
38
, of whatever acceptable width it might be. Once so received, operation of the motor
66
is terminated and operation of the motor
62
commenced. At this time, the wheels
56
,
58
rotate such that the associated pins
54
operate within the slots
52
of the rail support blocks
48
,
50
to move the rails
30
,
32
and the note stack
40
downwardly such that the gap
28
having the note
38
therein passes over the top plate
24
, with the top plate
24
making contacting engagement with the note
38
. The curvature of the top plate
24
is preferably the natural curvature of the note
28
as it is drawn out of slots
34
,
36
such that no acute bending or deflection of the note
38
is experienced. The note
38
is held upon the surface of the top plate
24
by the frictional strips
36
presented along the edges thereof. The stroke of rails
30
,
32
is sufficient for the side edges of the note
38
to be fully extracted from the slots
34
,
36
and to pass into the stack
40
in a left-justified manner. Once that travel has been made, operation of the motor
62
reverses and the rails return to their static position as generally shown in
FIG. 1
, awaiting receipt of the next bill.
As can be seen, the punch plate
24
is stationary, making no movement whatsoever during the stacking operation. Accordingly significant space savings is realized. The top of the punch may be arched or curved to the normal deflection arch of the paper currency to be stacked, and the slots
34
,
36
of the moving rails
30
,
32
are justified to one side (in alignment with a corresponding edge of the inlet slot to the validator) and are adapted to accommodate notes of various widths. The note stacker
10
in the housing
12
may be of a cassette nature such that the entire housing
12
and the components and cash therein may be simply replaced with an empty stacker
10
and housing
12
during routine servicing. Alternatively, the housing
12
may be provided with a door which may be opened such that the stack
40
of currency may be retrieved on site, or the housing
12
may be removable for such purpose.
Thus it can be seen that the objects of the invention have been satisfied by the structure presented above. While in accordance with the patent statutes only the best mode and preferred embodiment of the invention has been presented and described in detail, the invention is not limited thereto or thereby. Accordingly, for an appreciation of the true scope and breadth of the invention reference should be made to the following claims.
