## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a continuation of U.S. patent application Ser. No. 13/778,461, filed Feb. 27, 2013, entitled COIN COUNTING AND SORTING MACHINES, the contents of which is incorporated herein by reference in its entirety.


TECHNICAL FIELD
The following disclosure relates generally to coin processing machines and, more particularly, to machines for counting and sorting coins, such as consumer coins and the like.
BACKGROUND
Various types of consumer coin counting machines are known. Some coin counting machines (e.g., vending machines, gaming devices such as slot machines, and the like) are configured to receive one coin at a time through a slot. These types of machines are typically relatively simple because the coin input slot can define the maximum coin diameter and thickness, and because they are typically designed for low throughput and little if any coin cleaning. Such machines, however, are usually not satisfactory for counting a mass of consumer coins received at once (such as a mass of coins poured into a tray from, e.g., a coin jar).
Machines for counting relatively large quantities of consumer coins include those disclosed in, for example: U.S. Pat. Nos. 7,971,699, 7,874,478, 7,520,374, 8,033,375 and 8,332,313; each of which is incorporated herein by reference in its entirety. Some of these machines count consumer coins and dispense redeemable cash vouchers, while others may offer other types of products and services such as pre-paid gift cards, prepaid phone cards, and/or “e-certificates.” Vouchers can be redeemed for cash and/or merchandize at a point of sale (POS) in a retail establishment. E-certificates can enable the holder to purchase items online by inputting a code from the e-certificate when making the purchase. Prepaid gift cards can be used to make POS purchases by swiping the card through a conventional card reader, and prepaid phone cards can be used for making cell phone calls. All such machines typically include sensors and similar devices for discriminating coin denominations, coins from non-coin objects, and/or coins of one country from those of another.
Various types of sensors and other devices for identifying and/or discriminating coins in coin-counting machines are known. Such devices include those disclosed in, for example: U.S. Pat. Nos. 6,196,371 and 5,988,348; and U.S. patent application Ser. No. 13/269,121, filed Oct. 7, 2011 and entitled “AUTO-CALIBRATION SYSTEMS FOR COIN COUNTING DEVICES,” Ser. No. 13/489,043, filed Jun. 5, 2012, and entitled “OPTICAL COIN DISCRIMINATION SYSTEMS AND METHODS FOR USE WITH CONSUMER-OPERATED KIOSKS AND THE LIKE,” Ser. No. 13/612,429, filed Sep. 12, 2012, and entitled “AUTO-POSITIONING SENSORS FOR COIN COUNTING DEVICES,” and Ser. No. 13/691,047, filed Nov. 30, 2012, and entitled “DIFFERENTIAL DETECTION COIN DISCRIMINATION SYSTEMS AND METHODS FOR USE WITH CONSUMER-OPERATED KIOSKS AND THE LIKE;” each of which is incorporated herein by reference in its entirety.
Some coin counting machines collect all the coins they receive in a single receptacle regardless of denomination. As a result, the coins must be sorted by denomination after removal from the machine and before they can be put back into service. Accordingly, it would be advantageous to provide a coin processing machine that can count and sort large batches of coins.

DETAILED DESCRIPTION
The following disclosure describes various embodiments of coin processing machines that can count and sort coins. In various embodiments, the coin processing machines described herein are consumer-operated coin processing machines configured to receive large batches of random coins from users in exchange for, e.g., redeemable cash vouchers, prepaid cards (e.g., gift cards), e-certificates, etc. Certain details are set forth in the following description and in FIGS. 1-4 to provide a thorough understanding of various embodiments of the present technology. In some instances well-known structures, materials, operations and/or systems often associated with coin counting machines are not shown or described in detail in the following disclosure to avoid unnecessarily obscuring the description of the various embodiments of the technology. Those of ordinary skill in the art will recognize, however, that the present technology can be practiced without one or more of the details set forth herein, or with other structures, methods, components, and so forth.
The accompanying Figures depict embodiments of the present technology and are not intended to be limiting of its scope. The sizes of various depicted elements are not necessarily drawn to scale, and these various elements may be arbitrarily enlarged to improve legibility. Component details may be abstracted in the Figures to exclude details such as position of components and certain precise connections between such components when such details are unnecessary for a complete understanding of how to make and use the invention. Moreover, many of the details, dimensions, angles and other features shown in the Figures are merely illustrative of particular embodiments of the disclosure. Accordingly, other embodiments can have other details, dimensions, angles and features without departing from the spirit or scope of the present invention. In addition, those of ordinary skill in the art will appreciate that further embodiments of the invention can be practiced without several of the details described below.
In the Figures, identical reference numbers typically identify identical, or at least generally similar, elements. To facilitate the discussion of any particular element, the most significant digit or digits of any reference number refers to the Figure in which that element is first introduced. For example, element 110 is first introduced and discussed with reference to FIG. 1.
FIGS. 1A and 1B are isometric views of coin processing machines 100a and 100b, respectively, configured in accordance with embodiments of the present technology. In FIGS. 1A and 1B, certain exterior panels and/or other portions of the coin processing machines 100 have been removed to better illustrate interior structures and systems of the machines. Moreover, the main difference between the coin processing machine 100a shown in FIG. 1A and the coin processing machine 100b shown in FIG. 1B is that the two machines use two different types of coin receptacle for collecting counted and sorted coins. Otherwise, the two coin processing machines 100a and 100b are essentially the same and will be referred to hereinafter as the coin processing machine 100 for ease of reference.
Referring to FIGS. 1A and 1B together, the coin processing machine 100 (the “coin machine 100”) includes a horizontal service counter or shelf 108 mounted on a chassis 102. The shelf 108 supports a coin input region or basin 104 configured to receive large batches of coins (not shown) from consumers and/or other users. In the illustrated embodiment, the coin machine 100 further includes a user panel 106 positioned behind the shelf 108 that carries a number of user interface devices to facilitate use of the coin machine 100. For example, the user panel 106 can include a display 110, such as a display screen or LCD screen for providing users with prompts and other instructions for use of the machine 100. As those of ordinary skill in the art will appreciate, the display 110 can include touch pads and/or similar user input features enabling the user to select different operating parameters, products, and/or services of the machine 100. In other embodiments, the coin machine 100 can include keypads and/or other conventional user input devices for receiving instructions and/or other information from users. The service panel 106 can also include an outlet 114 for dispensing, e.g., redeemable vouchers and/or receipts to users in return for coins. The user panel 106 can further include a card reader 112 for reading (and/or writing to), e.g., magnetic stripes and/or other information storage media on various types of cards, such as prepaid cards, credit cards, identification cards, etc.
In operation, coins dumped into the basin 104 pass through one or more apertures or outlets 116 positioned toward a lower portion of the basin 104 and into a chute 134. The chute 134 delivers the coins into a first opening 119a of a coin cleaner 118 positioned below the shelf 108. In the illustrated embodiment, the coin cleaner 118 is a rotating coin cleaning drum (e.g., a “trommel”) that tumbles the coins as it moves them along the length of the coin cleaner 118 and out a second opening 119b. Such coin cleaning devices are described in detail in, for example, U.S. Pat. No. 7,464,802, which is incorporated herein in its entirety by reference.
In one aspect of this embodiment, the coin machine 100 further includes a coin processing unit 120 mounted in the chassis 102 beneath the coin cleaner 118. The coin processing unit 120 includes a coin counting portion having coin counter 122 and a coin sorting portion having a coin sorter 124. In the illustrated embodiment, the coin counter 122 includes a first coin hopper 126 and the coin sorter 124 includes a second coin hopper 127. Clean coins exiting the second opening 119b of the coin cleaner 118 fall into the first coin hopper 126 (the “first hopper 126”). As described in detail below, the coin counter 122 includes a rotating coin disk that lifts coins out of the first hopper 126 and places them onto a coin rail where they travel past a coin sensor for discrimination and counting. Coins that are properly counted then continue down the coin rail and into the second coin hopper 127 (the “second hopper 127”) for sorting. As also described in detail below, the coin sorter 124 also includes a rotating coin disk that lifts the coins out of the second hopper 127 and sorts them according to denomination.
In the illustrated embodiment, the coin machine 100 can further include one or more controllers for controlling operation of the various apparatuses and systems described above. For example, in the illustrated embodiment the coin processing machine 100 can include a first controller 136 for controlling operation of, e.g., the coin counter 122, and a second controller 138 for controlling operation of, e.g., the coin sorter 124. As those of ordinary skill in the art will appreciate, the controllers 136 and 138 can include, for example, programmable logic controllers (PLCs), and/or other types of processing, memory, and associated circuitry for controlling operation of the coin machine 100 according to computer readable instructions stored on suitable computer-readable media.
In some embodiments, the coin machine 100 can further include an “auto start” feature. More specifically, in these embodiments the coin machine 100 can include a sensor 140 (shown schematically in FIG. 1B), such as a vibration sensor, operably coupled and/or mounted to an underside portion of the coin basin 104. The sensor 140 can be configured to sense coins being dumped, poured, or otherwise placed into the basin 104, and send a corresponding signal to the first controller 136. The first controller 136 can be configured to automatically start rotation of the coin cleaner 118 (and, e.g., the coin counter 122 and the coin sorter 124) in response to the signal, thereby drawing coins into the coin cleaner 118 through the chute 134. In this way, the coin machine 100 does not require the user to input “start” instructions. Instead, the coin machine automatically starts when the user dumps his or her coins into the basin 104. In other embodiments, a vibration sensor can be mounted to the coin chute 134, and/or other types of sensors can be used to automatically sense or detect the presence of coins in the basin 104 and automatically turn the coin machine 100 on. In yet other embodiments, the machine 100 can require the user to input a start instruction to begin and/or continue a coin counting session.
In the embodiment illustrated in FIG. 1A, the coin machine 100a sorts the counted coins into a series of removable coin receptacles or bins 128 (identified individually as coin bins 128a-128h) positioned in a lower portion of the chassis 102. In some embodiments, the number of coin bins 128 used to hold the different coin denominations can vary depending on the expected prevalence of particular denominations during operation. For example, in one embodiment multiple coin bins 128 (e.g., 128a-c) can be used to hold pennies because they may tend to make up a large portion of the coins deposited by users, while single coin bins 128 (e.g., 128d-128h) can be used to hold other less prevalent denominations like dimes, nickels, quarters, and dollar/fifty cent pieces, respectively.
Although removable coin bins 128 are illustrated in FIG. 1A, in other embodiments other types of coin receptacles can be used for storage and transport of the sorted coins. As shown in FIG. 1B, for example, the coin machine 100 can alternatively include a plurality of coin drums 130 for collecting the various coin denominations. In this embodiment, the individual coin drums 130 can be fed coins of specific denominations by an arrangement of feed tubes 132. As described in greater detail below, each of the feed tubes is configured to receive a particular coin denomination from the coin sorter 124 and dispense the single denomination into a selected drum 130. In some embodiments, each of the feed tubes 132 can be automatically moveable and driven (by, e.g., a suitable electric motor—not shown) to position the respective tube outlets over an empty or new coin drum 130 when a previous coin drum becomes full of a specific coin denomination. In these embodiments, each of the coin drums 130 can be operatively connected to one or more sensors (not shown) that automatically determine when a particular drum is full. When one of the coin drums 130 is full, the associated sensor can send a control signal to the corresponding feed tube outlet, causing the outlet to move to another (e.g., empty) coin drum 130. Once a sufficient number of the coin drums 130 is full, the coin machine 100 can send an associated signal via a suitable communication facility to a remote operator station indicating that the coin drums 130 are sufficiently full and should be removed and replaced. In a further aspect of this embodiment, the coin drums 130 (and, similarly, the coin bins 128) can be carried by a movable dolly 131 having an associated handle 133 for easy removal and replacement of the coin drums 130 from within the coin machine 100.
FIG. 2 is an enlarged front isometric view of the coin processing unit 120 from the coin machine 100 of FIGS. 1A and 1B. As discussed above, the coin counter 122 includes a first coin disk 240 and the coin sorter 124 includes a second coin disk 260. In the illustrated embodiment, the first coin disk 240 and the second coin disk 260 revolve about central axes positioned at generally the same elevation (e.g., side by side rather than one above the other) and, as a result, the coin processing machine 100 has a relatively low profile. In operation, coins 244 fall into the first hopper 126 from the coin cleaner 118 as described above with reference to FIGS. 1A and 1B. The shape of the first hopper 126 causes the coins 244 to collect against the lower portion of the slightly inclined first coin disk 240. The first coin disk 240 rotates in direction R1 and lifts coins from the first hopper 126 on a series of paddles 242. The paddles 242 carry the coins 244 upwardly and place them at an entrance 245 to a coin rail 246. A coin peeler or similar device (not shown) can be used to knock grouped or misplaced coins off of the rail entrance 245 and back into the first hopper 126. Alternatively (or additionally), a debris diverter 248 can be positioned adjacent the coin rail 246 to ensure that the coins 244 proceed down the rail 246 in single file. In the illustrated embodiment, the debris diverter 248 can be at least generally similar in structure and function to similar devices described in detail in U.S. patent application Ser. No. 13/228,676, filed Sep. 9, 2011, and entitled “DEBRIS DIVERTER FOR COIN COUNTING MACHINE AND ASSOCIATED METHOD OF MANUFACTURE AND OPERATION;” which is incorporated herein by reference in its entirety. In other embodiments, the debris diverter 248 can be omitted. Once past the debris diverter 248, the coins 244 proceed down the coin rail 246 past a coin sensor 250. By way of example, the various coin cleaning, sensing, counting, and/or other features, components and systems associated with the coin counter 122 described herein can be at least generally similar in structure and function to one or more of the coin cleaning, sensing and counting systems described in detail in the patents and and/or patent applications listed above and incorporated herein by reference.
In the illustrated embodiment, the coins 242 that are properly discriminated as they pass by the sensor 250 are counted and deflected into a first coin passage 252a by a movable door 254. The counted coins 242 then flow from the first passage 252a into the second coin hopper 127. Conversely, coins that cannot be properly discriminated and/or are determined to be fraudulent or otherwise unwanted coins or other objects are allowed to roll into a second coin passage 252b. From the second coin passage 252b the unwanted coins 242 pass to a coin return chute 256 from which they are returned to the user at the front of the machine 100. As a result of this process, the second coin hopper 127 only receives the coins 242 that have been discriminated and counted.
FIG. 3 is an enlarged front isometric view of a portion of the coin sorter 124 with the second hopper 127 removed for clarity. Referring to FIGS. 2 and 3 together, the second coin disk 260 is configured to rotate in direction R2 about its central axis on a back plate 272. The back plate 272 can be manufactured from various suitable materials known in the art including, for example, high-density polyethylene (HDPE), ultra-high-molecular-weight polyethylene (UHMW), also known as high-modulus polyethylene (HMPE), etc. As described below with reference to FIG. 4, the coin disk 260 can be driven by an electric motor or other suitable drive system mounted on the opposite side of the back plate 272. The coin disk 260 includes a plurality of coin apertures or pockets 268 (identified individually as coin pockets 268a-268n) positioned around a periphery thereof. The coin pockets 268 can be generally equivalent in size, and can have rounded corners and/or other dimensional features shaped and sized to hold the coins 242 received from the second hopper 127. By way of example, the coin disk 260 can have an outer diameter ranging from about 6 inches to about 12 inches, or about 8 inches. The coin disk 260 can manufactured from various suitable metallic and non-metallic materials known in the art including, for example, stainless steel, polyurethane, Teflon, etc. In other embodiments, the coin disk 260 can have other suitable diameters and can be manufactured from other suitable materials.
In the illustrated embodiment, the coin sorter 124 further includes a coin sensor 262, a coin displacer 264, a coin deflector 266 and a series of coin movers 270 (identified individually as coin movers 270a-270e) positioned adjacent the outer periphery of the coin disk 260. The back plate 272 includes a series of coin apertures 386 (identified individually as coin apertures 386a-386e) positioned directly beneath the coin movers 270a-270e and aligned with the path of the coin pockets 268. Each of the coin apertures 386 is sized to only permit passage therethrough of a coin or coins of particular denominations. For example, in the illustrated embodiment the first coin aperture 386a can have an outer diameter that is only slightly larger than the diameter of a smallest desired coin, such as a U.S. dime. Similarly, the second coin aperture 386b can have an outer diameter that is only slightly larger than the diameter of the next-biggest desired coin, such as a U.S. penny. Likewise, the third coin aperture 386c can have an outer diameter that is only slightly larger than a U.S. nickel, the fourth coin aperture 386d can have an outer diameter that is slightly larger than a U.S. quarter, and the fifth coin aperture 386e can have an outer diameter that is slightly larger than U.S. 50 cent or dollar coins. The foregoing arrangement of coin apertures 386 ensures that no coin larger than a dime passes through the first coin aperture 386a, that no coin larger than a penny passes through the second coin aperture 386b, that no coin larger than a nickel passes through the third coin aperture 386c, and so on.
The coin pockets 268 can be shaped and sized to carry the individual coins 242 in or near a certain position in the pocket (e.g., toward an aft inner corner of the pocket) as the coins 242 move under the coin sensor 262. In the illustrated embodiment, the coin sensor 262 can include, e.g., one or more infrared sensors that detect information relating to the size (e.g., the diameter) of the coin 242 (or coins) moving through the field of the sensor 262. This information can be provided to the coin sorter controller 138 (FIG. 1B) for determining whether there is a single coin 242 in each pocket 268 or multiple coins, and if a single coin, the coin diameter. In the illustrated embodiment, the coin displacer 264 includes plurality (e.g., three) ribs or blades 265 that are normally retracted into the back plate 272. If the coin sorter controller 138 determines (based on information from the coin sensor 262) that that there are multiple coins 242 in a particular coin pocket 268, the controller 138 sends a corresponding signal to the coin displacer 264. The signal causes the coin displacer 264 to momentarily drive the blades 265 outwardly through the back plate 272 (by, e.g. a solenoid or other suitable device) when the coin pocket 268 is positioned directly over the blades 265. This knocks the jumbled coins 242 out of the coin pocket 268 and back into the second hopper 127.
In the illustrated embodiment, the coin deflector 266 is a metallic blade having an edge 380 positioned a predetermined distance D above the rotating surface of the coin disk 260. If two or more coins are knocked out of one of the coin pockets 268 by the coin displacer 264, the coins will strike the coin deflector 266 and be deflected back into the second hopper 127. Accordingly, the first coin displacer 264 and the coin deflector 266 cooperate to ensure that each of the coin pockets 268 only carries a single coin 242 over the series of coin apertures 386 in the back plate 272 during operation of the coin sorter 124.
Each of the coin movers 270 is mounted to a corresponding bracket 382 which is in turn mounted to the back plate 272. The bracket 382 can be formed from sheet metal or other suitable materials known in the art. In the illustrated embodiment, the coin movers 270 can all be the same type of electrically-actuated device (e.g. a solenoid) having a corresponding plunger or push rod 274 configured to momentarily extend outwardly therefrom beneath the bracket 382 upon actuation. In addition to the coin movers 270, a resilient deflector 384 can also be mounted to a distal portion of each bracket 382. In the illustrated embodiment, the deflectors 384 can be formed from thin, spring steel or similar material. Each deflector 384 is cantilevered outwardly from an edge of the corresponding bracket 382 so that a distal end portion of the deflector 384 is positioned beneath the corresponding coin mover 270 and directly above the adjacent coin aperture 386 in the back plate 272. When extended, the push rod 274 presses against the distal end portion of the corresponding deflector 384, thereby causing the deflector 384 to move downwardly into the adjacent coin pocket 268 and knock the coin 242 therein through the adjacent coin aperture 386 in the back plate 272.
During operation of the coin processing unit 120, the coin counter 122 discriminates and counts the coins 242 before passing them into the coin sorter hopper 127. The term “discriminate” as used herein means to determine whether the coin is a desired coin by determining or verifying, e.g., the coin denomination, authenticity, country, etc. As the coin disk 260 rotates in direction R2, the coins 242 in the hopper 127 fall into the moving coin pockets 268 and are carried upwardly past the coin sensor 262. If a single coin 242 is present in the coin pocket 268, the coin sensor 262 determines the diameter of the coin. Because only authentic and desired coins 242 are allowed to proceed into the coin hopper 127, the coin diameter is the only piece of information needed to determine the coin denomination. More specifically, since all the coins 242 in the coin hopper 127 will be, for example, authentic U.S. coins, there is no need to determine the metallic content to confirm authenticity and denomination. Instead, the coin denomination can be determined simply by knowing the coin diameter. After the coins 242 pass under the coin sensor 262, they move over the coin displacer 264, which is normally retracted into the back plate 272 to allow the coins 242 to pass. If, however, the coin sensor 262 determines that multiple coins 242 are positioned in one of the pockets 268, the coin displacer 264 strikes the coins as the pocket 268 moves past and knocks the coins out of the pocket 268. The knocked coins 242 then strike the coin deflector 266, which in turn deflects the coins back into the hopper 127. As a result of this process, only single coins 242 that are properly positioned in the pockets 268 are allowed to pass over the series of coin apertures 386 in the back plate 272.
When the coin sensor 262 determines the diameter of a particular coin 242, it sends a signal to the corresponding coin mover 270 via the coin sorter controller 138. For example, if the coin sensor 262 determines that a particular coin 242 is a U.S. dime, the controller 138 sends a signal to the first coin mover 270a when the dime is positioned directly over the first coin aperture 386a in the back plate 272. The signal causes the first coin mover 270a to momentarily drive the corresponding plunger 274a outwardly against the underlying deflector 384, which causes the deflector 384 to momentarily move into the adjacent coin pocket 368 and knock the dime through the aperture 386a in the black plate 272. Similarly, if the coin sensor 262 determines that a particular coin 242 is, for example, a nickel, then the coin sensor 262 sends a signal to the third coin mover 270c at an appropriate time for the third coin mover 270c to drive the corresponding plunger 274c against the adjacent deflector 384 and knock the nickel through the third coin aperture 386c in the back plate 272. In the foregoing manner, all of the coins in the coin sorter hopper 127 can be properly sorted by passing them through the appropriate coin aperture on the back plate 272.
Referring to FIG. 3, the coin disk 260 can be coupled to its drive system (not shown in FIG. 3) with a shock absorbing apparatus to prevent or at least limit damage to the coin disk 260 or related components from a sudden jam. For example, in the illustrated embodiment the coin disk 260 is mounted beneath a central hub 388. The hub 388 carries a plurality of anchors or studs 390 fixedly attached thereto, and a plurality of arcuate slots 396 positioned between the adjacent studs 390. A plurality of dowels or guide pins 392 are fixedly attached to the coin disk 260 and extend upwardly therefrom through the slots 396. The guide pins 392 enable the disk 260 to rotate back and forth relative to the hub 388 between the end portions of the slots 396. A resilient biasing member 394 (e.g., a coil spring) extends between each dowel pin 392 and the nearest stud 390 in the direction R2. During normal operation, the biasing members 394 bias the dowel pins 392 against a first end portion of the corresponding slot 396. If, however, the coin disk 260 encounters a jam or is otherwise stopped abruptly during operation, the hub 388 can continue to rotate for at least the length of the slots 396 before the hub 388 applies substantial force to the coin disk 260 and potentially causes damage. This shock absorbing feature provides a short period of time for detecting a jam in the system (with, e.g., a suitable sensor known in the art) and shutting off the drive system before damaging the coin disk 260 and/or the drive system.
FIG. 4 is a rear isometric view of the coin processing unit 120 described above with reference to FIGS. 2 and 3. As this view illustrates, the coin displacer 264 can include an actuator 402 (e.g., a solenoid) that can be positioned to extend the blades 265 described above with reference to FIG. 3. This view also illustrates mounting of a drive system 410 (e.g., a suitable electric motor, gear system, etc.) on the back plate 272 for rotating the coin disk 260 during operation of the coin sorter 124. In addition to the foregoing features, a plurality of coin passages or tubes 406a-406c are also mounted to the backside of the back plate 272 over corresponding ones of the coin apertures 386. For example, the first coin tube 406a is mounted to the back plate 272 to receive coins passing through the first coin aperture 386a, the second coin tube 406b is mounted to the back plate 272 to receive coins passing through the second coin aperture 386b, and so on. As a result of this arrangement, only coins of a single denomination will pass through each of the individual coin tubes 406.
Although shown schematically in FIG. 4 for purposes of illustration, additional sections of tube or other types of passageways can extend from the outlet of each of the coin tubes 406 to a corresponding bin inlet 408. The bin inlets 408 can distribute the coins into the coin bins 128 described above with reference to FIG. 1A. For example, the first coin tube 406a can transfer coins of a first denomination (e.g., dimes) into the coin inlet 408a, the second tube 406b can similarly transfer coins of a second denomination (e.g., pennies) into the second coin inlet 408b, and so on. Similarly, each of the respective coin inlets 408 can include partitions and/or other structures which direct the received coins into the desired bins 128. Alternatively, as described above with reference to FIG. 1B the moveable coin feed tubes 132 and/or similar structures can also be coupled to the outlets of the coin tubes 406 to distribute the coins of specific denominations into the coin drums 130.
As those of ordinary skill in the art will appreciate, once coins have been sorted into denominations with the coin sorter 124 described in detail above, any number of structures and systems can be used to deposit the sorted coins into separate receptacles for transport and/or later use. One advantage of these embodiments is that the coins do not have to be sorted by a separate process after the counted coins have been removed from the coin processing machine 100. This can simplify the task of returning the coins to circulation.
