FIELD OF THE INVENTION
[0001] The present invention relates to banknote validators having an associated cashbox
and in particular to the connection between the cashbox and the banknote validator
allowing banknotes to pass from the validator to the cashbox.
BACKGROUND OF THE INVENTION
[0002] Banknote validators with locking banknote cassettes or non locking cashboxes are
well known and have particular application for standalone payment systems where there
may or may not be security personnel present.
[0003] Banknote validators and associated cashboxes for gaming machines and other applications
where the value of the accumulated banknotes is relatively high, typically use a locking
banknote cassette. In lower value applications such as vending machine applications,
the value of accumulated banknotes received as part of the payment process is significantly
less and a more cost effective arrangement of the banknote validator and cashbox is
often required. For vending machine applications, it is known to use a plastic cashbox
and it is also known to use a plastic cashbox with an open port. This simplified plastic
cashbox is significantly less secure relative to a locked banknote cassette however
it provides a low cost system. The open port plastic cashbox is typically used where
the denomination of the currency being accumulated is relatively low and/or the operator
demands a price point for the combination banknote validator and cashbox that is particularly
aggressive.
[0004] The present invention relates to a banknote validator having a cashbox of the open
port type that has improved properties reducing the possibility of banknote jamming
when passed from the validator to the cashbox.
[0005] In banknote validators and plastic cashboxes, the cashbox is generally connected
to the banknote validator for feeding of the banknote along one face of the cashbox
to overlap with the open port. The banknote is appropriately positioned by the banknote
validator in front of the open port and a stacking mechanism forces the banknote through
the port and into the cashbox. Typically a banknote validator has an initial banknote
evaluating channel of a first generally straight orientation connected to a curved
transition followed by a second generally straight segment having a direction generally
perpendicular to the first direction. The curved transition is normally a smooth curve
defined entirely by the banknote validator and guides the banknote through the change
in direction of travel and connecting with an outlet of the validator. The cashbox
is then positioned adjacent the outlet and the banknote is moved or passed along a
front face of the banknote receiving port in the cashbox.
[0006] With the prior art arrangement described above, a banknote can become jammed in the
banknote validator or at the junction of the cashbox and the banknote validator. Banknote
validators can include various arrangements including software arrangements for controlling
the drive of the banknote validator to assist in clearing of jammed banknotes, however
jamming of banknotes remains a significant problem as the banknote validator is forced
to a service required condition. This outage in service typically reduces sales and
can frustrate both customers and the service providers.
[0007] It is desired to provide an improved arrangement for processing of banknotes and
stacking of the banknotes in a cost efficient and reliable arrangement.
SUMMARY OF THE INVENTION
[0008] A banknote validator according to the present invention comprises a validating head
having a banknote processing channel for assessing the authenticity of banknotes and
a releasable cashbox connected to the validating head for stacking authenticated banknotes.
The validating head includes a banknote inlet at one end of the banknote processing
channel and a banknote outlet at an opposite end of the banknote channel. The banknote
outlet cooperates with an end of the cashbox to collectively define a curved transition
guiding an authenticated banknote through an angle of at least 90° leading to a stacking
port in a side of the cashbox. The cashbox and validating head have interfitting surfaces
collectively defining an outside guide structure of the curved transition when the
cashbox is secured to the validating head. A drive arrangement drives banknotes through
the banknote processing channel, and if authenticated, through the curved transition
to the stacking port. A stacking mechanism is provided for selectively pushing a banknote
through the stacking port and into the cashbox.
[0009] In a preferred aspect of the invention the banknote validator has a particular drive
arrangement that includes two lead drive rollers located in the validating head and
defining a portion of the curved transition.
[0010] The drive arrangement further includes cooperating responsive rollers on opposite
sides of the processing channel on a front side of the curved transition and a pair
of downstream responsive rollers supported in the cashbox adjacent a discharge of
the curved transition. Each of these responsive rollers cooperate with the associated
lead drive rollers to engage and guide a banknote towards the stacking port of the
cashbox.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] The sectional view of Fig. 1 shows a banknote validator 2 having a banknote validating
head 4, and a cashbox 6 where banknotes enter through the banknote inlet 8, pass through
the processing channel 10 to the curved transition 12, and if authenticated, are driven
to overlap with the stacking port 40 of the cashbox 6. The arrangement of Fig. 1 has
a particular drive arrangement and banknote processing pathway which distinguishes
it from the prior art. It can be seen from a review of Figures 2 and 3 that the curved
transition 12 which forms part of the banknote processing channel is defined between
a portion of the validating head 4 and an end portion of the cashbox 6. This curved
transition allows an authenticated banknote to be driven and positioned in front of
a port of a cashbox. The curved transition essentially joins the two straight segments
that have a generally 90° orientation.
[0013] The curved transition is defined by a portion of the cashbox and a portion of the
validating head. This is in contrast to prior art arrangements where the curved transition
is entirely formed within the validating head and the cashbox abuts with an offset
discharge from the validating head after the banknote has been processed through the
curved transition.
[0014] It has been found that banknotes may become jammed or lodged at a curved transition
in the banknote processing path and/or at the connection to the cashbox. In contrast
to the prior art arrangement, the curved transition of the present system is collectively
defined between the cashbox and the validating head and thus the separate interface
between the cashbox and the validating head is avoided. This reduces the number of
locations where a banknote may become jammed and the arrangement has been found to
be more reliable.
[0015] As seen in Fig. 2, the validating head 4 includes an outside portion 5 that defines
part of the exterior of the curved transition 12. The one end 15 of the cashbox 6
defines a second portion of the curved transition. Basically the cashbox includes
a series of interfitting or overlapping surfaces 62 as shown in Fig. 3 which cooperate
with the interfitting surfaces 60 of the outside portion 5 of the validating head
4. These interfitting surfaces form stationary parts of the exterior surface of the
curved transition.
[0016] It can also be seen in Fig. 3 that the outside portion 5 of the validating head 4
includes two cooperating responsive rollers 24 that engage the drive roller 22 shown
in Fig. 1. Basically there are 2 drive rollers on either side of the validating head
and positioned within the curved transition as best shown in Fig. 1. A banknote passing
through the banknote channel and the curved transition is engaged by each of the drive
rollers 22 and the cooperating responsive rollers 24 as part of the validating head
and the cooperating responsive rollers 48 that are supported in the cashbox. As illustrated
in the sectional view of Fig. 1, the drive roller 22 is engaged by the responsive
roller 24 and the responsive roller 48 of the cashbox. With this arrangement, a banknote
that is approaching the curved transition is initially engaged in the gap between
the responsive roller 24 and the drive roller 22 and the associated drive belt. The
banknote is driven through the curved transition and subsequently engaged between
the responsive roller 48 and the drive roller 22. This arrangement for controlling
of the banknote as it passes through the curved transition has proven to be very effective.
With this arrangement the cashbox forms the second portion of the curved transition
in combination with an inner surface of the validating head 4.
[0017] The drive roller 22 is oversized relative to the responsive rollers and preferably
is of a diameter at least twice the diameter of the responsive rollers. With this
arrangement the drive belts and the drive rollers drive the banknote throughout the
curved transition.
[0018] Figures 5 and 6 show a further feature of the present invention. The drive roller
22 is actually a combination drive roller having a drive roller segment 34 which engages
roller segment 26 of the cooperating responsive rollers 24 and 48. The drive roller
22 also includes a belt drive gear segment 36 shown in Fig. 7 that cooperates and
drives the drive belt 30. With this structure, both the drive belt 30 (and there are
a pair of drive belts 30 provided either side of the banknote channel) and the drive
roller segment 34 control the banknote as it passes through the curved transition.
At the discharge side of the curved transition, the drive belts 30 continue to drive
the banknote downwardly as these drive belts are positioned either side of the stacking
port 40 in the banknote cassette. It can also be appreciated that the drive roller
segments of the drive rollers also force a banknote downwardly so that it can assume
an overlapped position with the stacking port 40 of the cashbox 6 to allow stacking
therein. With banknotes of different widths, this has been effective in reducing jamming
events. The outside position of the banknote drive belts is preferred as they extend
either side of the port 40. A return roller for each drive belt is generally shown
as 49.
[0019] Fig. 5 shows a pusher plate 70 that includes its own motor for forcing of the pusher
plate through the stacking port 40 and any banknote in front of the stacking port
to push a banknote into the cashbox.
[0020] With the present structure, the curved transition is formed between the cashbox and
the banknote validating head. The inner portion of the curved transition is defined
in the validating head by the banknote channel and the drive rollers 22 and the drive
belts. The outer portion of the curved transition is partially defined by the validating
head (i.e. the outside portion 5) and the one end of the cashbox such that a banknote
is only prone to jamming in the curved transition and the cashbox and validating head
have a pass off point that is collectively defined within the curved transition. By
positioning the drive roller 22 in the curved transition and of a diameter to allow
it to engage the banknote as it enters the curved transition as well as when it leaves
the curved transition, the drive roller maintains control over the banknote and provides
an effective hand off as the processing channel of the banknote on the exterior thereof
changes from the banknote validating head to the cashbox.
[0021] The particular cooperation of the elements in the interlapping surfaces or fingers
at the curved transition to collectively form the curved transition reduces jamming
and effectively controls the banknote as it passes between the validating head and
the cashbox. This arrangement, particularly in combination with the double drive arrangement
(rollers and drive belts), provides increased reliability.
[0022] Figures 7 and 8 show additional details of the drive roller and the cooperating responsive
roller. Fig. 7 is a perspective view of the drive roller 22 which includes the gear
drive segment 36 for engaging teeth on the back surface of the drive belts as well
as a drive roller segment 34. This drive roller segment can be of an appropriate rubber
material or other suitable material for engaging the banknote as it passes through
the curved transition.
[0023] The responsive roller 34 and the responsive roller 48 are preferably of the same
design as shown in Fig. 8. A drive roller segment 34 engages the opposite roller segment
26 and a spaced belt drive gear segment 36. These elements cooperate with the outer
surface of the belt drive to appropriately drive the banknote with rotation of the
roller. It can be seen that the two segments 34 and 36 are separated by a center recessed
portion 35. This is preferred to allow each of the segments 34 and 36 to respectively
function independently of one another although tied to the rotation of the roller.
[0024] Although various preferred embodiments of the present invention have been described
herein in detail, it will be appreciated by those skilled in the art, that variations
may be made thereto without departing from the invention as defined in the appended
claims.
