Used by banks, currency exchanges, vending business, arcades,
restaurants, stores, and any other establishment that goes through a
lot of cash and change, money sorters come in assorted sizes,
configurations and price ranges. A money sorter can be very simple or
quite elaborate. From children's banks that separate coins by
denomination to money sorters that place coins into rolls and tally the
exact amount, these devices make categorizing money simple. There are
machines that separate and count bills as well, making a money sorter a
convenient tool for sorting, counting and organizing coins and bills
alike.
A
coin sorter
for sorting coins of mixed diameters is set forth. The sorter includes
a coin-driving member and a coin-guiding member. The lower surface of
the coin-guiding member forms a plurality of exit channels for guiding
coins of different diameters to different exit stations along the
periphery of the coin-guiding member. The coin sorter includes a brake
mechanism which permits stopping of the coin-driving member at high
speeds such that an invalid coin is retained or for ensuring the
correct amount of coins is sent to the coin-collecting receptacle. The
coin sorter also includes an operator interface panel for easy operator
inputs. Operator inputs allow the operator to adjust the movement of
the coin-driving member after encountering a stop and for adjusting the
amount of lubrication sent to the coin-guiding member.
At home, a
money sorter machine
is a great device for teaching children to save money. As they put
coins into their banks, kids can see how quickly the money adds up.
Before long, a child has an entire roll of coins that can be added to
his or her savings or exchanged for bills. A money sorter is also handy
for adults, especially if they handle a lot of change or singles at
work. Someone who earns tips for example, might find a money sorter
very convenient.
A quality money sorter is very sturdy, reliable and simple to use. Many
are so simplistic that all you have to do is pour in change or load a
stack of bills and let the machine do the work. A money sorter can sort
coins and bills by denomination, organizing them and counting them at
the same time. Many even check the authenticity of the money, removing
counterfeit notes and coins from the rest of the currency.
In business, time is money, so the quicker money can be sorted,
counted, rolled and stacked, the better it is for the business owner.
It is also important to detect counterfeit money, which
money sorters can do with UV light or a magnetic component.
Money sorters can also be purchased with different speeds. Some can
count as many as 1,000 bills in just one minute. These devices are easy
to use and some models can be hooked up to your computer. There are
also portable, battery operated models.
Although coin sorters have been used for a number of years, problems
are still encountered in this technology. For example, friction of the
moving coins on the surface of the coin-guiding member can cause
galling of that surface. If softer metals are used in coins, some of
the softer metal may fuse into the surface of the coin-guiding member.
It would be advantageous to have a coin sorter which could not only
apply lubrication to the coin-guiding member, but vary the amount of
lubrication and the frequency of lubrication by simple operator inputs.
To accomplish exact bag stopping or the expulsion of an invalid coin,
the moving components of the system must be decelerated at high rates
to ensure that the trigger coin (the invalid coin, or the last coin to
be placed in a bag) enters the correct chute. This requires an extreme
brake force to be exerted on some of the moving components in the
coin sorter manufacturer
when coins are being sorted and discharged at the rate of over 4000
coins per minute. This excessive brake force leads to substantial wear
on the brake components. Thus, it would be useful to have an apparatus
which continuously adjusts the braking mechanism at an optimum
deceleration rate, that is not too excessive, so as to conserve the
amount of wear on the brake components.
Furthermore, stopping is often necessary to ensure that only the
trigger coin enters the bag. It would be useful to have a bag switching
mechanism which would only require the coin sorter to decelerate, and
not stop. Thus, the rate of sorting and discriminating would increase
if only deceleration were needed. And, the wear on the braking
components would decrease. This problem is accentuated when the sensors
detecting the coin are in the exit channels near the periphery of the
sorting head.
Because the exact bag stop feature may encounter problems in that the
trigger coin may not fully discharge from the sorting head due to
deviations in the braking mechanism or drive motor, it would be useful
to have a feature which allowed the operator to change the amount of
angular displacement of the coin-driving member after the trigger coin
is detected. Such a feature would provide a user with simplistic means
to correct this problem without having to modify the braking mechanism
or the coin-driving member. It would also be beneficial to have a coin
collection system which would allow the
coin sorter to continue operation even though the coin limit for one denomination is reached.
It is a primary object of this invention to provide an improved coin
sorter which can be operated at extremely high speeds and with a high
degree of accuracy.
In accordance with the present invention, the foregoing objective is
realized by providing a coin sorter which includes a rotatable disc
having a resilient top surface and a stationary sorting head having a
lower surface positioned parallel to the upper surface of the disc and
spaced slightly therefrom. The coin sorter also includes an operator
interface panel and a controller for operating the coin sorter.
The operator interface panel allows the operator to adjust the amount
of lubrication by modifying the frequency and lubrication pulsing
duration at which the lubrication is discharged. Consequently, every
coin sorter product discharges the lubrication at a rate which is desirable for that specific coin sorter.
Further, the operator, via the operator interface panel, can adjust the
amount of disc rotation which occurs after a trigger coin is sensed on
the disc to ensure that the trigger coin is completely discharged from
the disc, and that the coin following the trigger coin remains on the
disc.
Another benefit of the coin sorter described herein is that the
operator has the ability to quickly initialize and store in the memory
of the controller the characteristic pattern against which the coins of
a particular denomination are compared for determining coin validity.
The coin sorter also utilizes an internal brake adjust feature which
permits the coin driving member to stop accurately, but without over
using the braking mechanism. Thus, the service life of the brake
mechanism is increased.
Additionally, the
coin sorter supplier
includes a dual path bag clamping mechanism having a guiding mechanism
that switches the flow of coins between the two bags. The bag clamping
mechanism also has a single path version as well. In either bag
clamping mechanism, a novel bag interlock mechanism ensures that a bag
is properly secured before the coin sorter discharges coins into the
bag clamping mechanism.
Also, the guiding mechanism of the bag clamping mechanism that switches
the flow of coins between the two bags is positioned far enough along
the path of the coin beyond the periphery of the disc that the disc
only needs to be decelerated, and not stopped, to perform an exact bag
stop.
The above summary of the present invention is not intended to represent
each embodiment, or every aspect, of the present invention. This is the
purpose of the figures and the detailed description which follow.
