Description

Description: BACKGROUND OF THE INVENTION (Industrial Application Field) The present invention relates to a coin processing machine used by being incorporated in a cash register or the like, for example.

(Prior Art) A conventional cash register has a calculation function such as a sales calculation, a change calculation for a received amount, and the like, but coins are manually paid and paid. That is, the supply of change to the drawer is manually distributed for each denomination, and the change is taken out from the drawer while counting manually.

(Problems to be Solved by the Invention) The conventional cash register requires a great deal of time and effort, and is liable to cause errors because all coins are manually put in and out.

By the way, there are coin processing machines used in financial institutions and the like, and when various coins are inserted in a mixed state,
There is a technology (for example, Japanese Utility Model Publication No. 60-22451) capable of selecting coins and stocking them by type, and a technology (for example, Japanese Utility Model Application Publication No. 56-20854) that can appropriately pay out a required number of coins. However, no technology has been developed that can automatically perform the operations from the input of trading value to the payment of change.

The present invention is capable of automating from the input of the trading value to the sorting of coins, the storage, the dispensing of change, and the overflow when coin storage is not necessary, and also allows the coins to be easily and reliably sorted into storage and overflow on each receiving belt. It is an object of the present invention to provide a coin processing machine.

Another object of the present invention is to provide a coin processing machine that can reliably transfer coins by appropriately setting the positional relationship between the receiving belt 15 and the overflow belt.

(Means for Solving the Problems) A first specific configuration for solving the problems in the present invention is a receiving hopper mechanism A for sending out coins M inserted in a mixed state one by one, and this receiving hopper mechanism A A sorting mechanism B having a sorting plate 7 for sorting coins M sent out from a plurality of coin windows W, a receiving conveyor mechanism C having a plurality of receiving belts 15 for transferring sorted coins for each coin, The change hopper mechanism D for dropping the coins on each of the receiving belts 15 to receive and store the required number of coins, and the coins dispensed from each change hopper mechanism D are collected and transferred to the change tray 52. A pay-out conveyor mechanism E having a pay-out belt 51 and the change hopper mechanism D
Overflow mechanism F having an overflow belt 53 for receiving coins from the receiving belt 15 and transferring them to the overflow tray 54 in place of the change hopper mechanism D when coin storage is not necessary.
A coin dropping unit D26 for dropping coins M onto the change hopper mechanism D and a coin dropping unit F26 for dropping coins onto the overflow belt 53 are arranged above the receiving belt 15. These coin dropping means D26 and F26 are arranged in the coin transfer direction of the receiving belt 15, and the means located on the front side is a fixed coin dropping means which is always in a coin falling state, and the means located on the near side. Is a movable coin dropping means that can be switched between a coin falling state and a coin currency state. The second specific configuration is a receiving hopper mechanism A that sends out coins M inserted in a mixed state one by one. , The coin M sent from the receiving hopper mechanism A
A sorting mechanism B having a sorting plate 7 for sorting through a plurality of types of coin windows W, and a receiving conveyor mechanism C having a plurality of receiving belts 15 for transferring sorted coins for each coin.
And a change hopper mechanism D for dropping the coins on each of the receiving belts 15 to receive and store the required number of coins, and a set of coins dispensed from each change hopper mechanism D to the change tray 52. An overflow having a dispensing conveyor mechanism E having a dispensing belt 51 to be transported, and an overflow belt 53 for receiving coins from the receiving belt 15 and transferring the coins to the overflow tray 54 instead of the change hopper mechanism D when the change hopper mechanism D does not need to store coins. A mechanism F and a coin dropping means D26 for dropping coins M onto the change hopper mechanism D and a coin dropping means F26 for dropping coins onto the overflow belt 53 are arranged above the receiving belt 15. , The plurality of receiving belts 15 are a set of two belts, and each set of receiving belts 15 has an interval at which coins can be dropped.
The height 56 of the receiving belt 15 from the upper surface of the overflow belt 53 is substantially equal to or less than the coin diameter, and the gap 55 between the upper surface of the overflow belt 53 and the receiving belt 15 is larger than the coin thickness and the coin diameter. Is set to approximately one-half or less.

(Operation) When coins M as a trading value are received in a mixed state into the receiving hopper mechanism A, the coins are sent out one by one to the sorting mechanism B, and sorted by the coin window W of the sorting plate 7 for each type.
The sorted coins are transported by the respective receiving belts 15 and supplied to the change hopper mechanism D. Each change hopper mechanism D stores coins, receives a change payout signal, pays out the required number of change coins, and supplies the change coins to the change tray 52 via the payout conveyor mechanism E. When the supply of coins to the change hopper mechanism D becomes unnecessary, the coins on the receiving belt 15 are supplied to the overflow belt 53 and collected in the overflow receiving tray 54. On the receiving belt, a movable coin dropping unit is disposed on the front side in the transfer direction, and a fixed coin dropping unit is disposed on the front side. One of the two units corresponds to the change hopper mechanism D, and the other corresponds to the overflow belt 53. When the movable coin dropping unit is in a coin falling state, a coin is dropped therefrom. When the movable coin dropping unit is in a coin currency state, a coin is dropped by the fixed coin dropping unit.

The receiving belts 15 are a set of two, and have an interval 23 between which coins can be dropped, and coins M dropped from one of the receiving belts 15 of each set by the coin dropping means F26. Is that the falling direction is opposite to the coin transfer direction of the overflow belt 53, and the coin abuts on the receiving belt 15 and the overflow belt 53 at the same time during the fall, and then there is a gap 55 between the two belts 15, 53. As a result, the coin M rotates once and is placed flat on the overflow belt 53.

In the vicinity of the payout port 40 on the outer periphery of the change hopper 28, a counting means
43 are provided. The counting means 43 engages with the coin M to be ejected and turns, a star wheel 44 which rotates when the star wheel 44 turns, and a roller 45 which is pushed by the roller 45 and is operated by being pushed by the roller 45. Has a counter 46,
The number of coins to be paid out is counted.

A shortage sensor 47 is provided in the middle of the change hopper 28, and a full-batch sensor 48 is provided in the upper portion thereof. For example, a photoelectric tube is used for both sensors 47 and 48.

The remaining sensor 47 is activated when the number of coins in the change hopper 28 is less than a certain value (for example, 20 to 40), and the full sensor 48 is activated when the number of coins is more than a certain value (for example, 100 to 120). The two sensors 47 and 48 are provided with the phase changed in the circumferential direction with respect to the change hopper 28, but they may be arranged in the same phase.

In FIGS. 1, 3, 4, 11, and 12, the payout conveyor mechanism E has a payout belt 51 and a change tray 52, and the overflow mechanism F has an overflow belt 53, an overflow tray 54, and coin dropping means F26. The payout belt 5
The 1 and the overflow belt 53 are arranged so as to overlap in the vertical direction, and the change tray 52 and the overflow tray 54 are arranged adjacent to each other on the left and right.

The payout belt 51 and the overflow belt 53 are one by one, and are inserted between the front and rear pairs of change hopper mechanisms D arranged for three sets of the receiving belts 15 in total, so that all change hopper mechanisms are provided. D, the coins are transported in the same direction, are orthogonal to the receiving belt 15 in plan view, the payout belt 51 is at the lowest position, and the overflow belt 53 is a gap 55 below the receiving belt 15. Is located through.

The payout belt 40 has a payout port 40 of all change hoppers 28 facing the change hoppers 28. The change payouts from the change hoppers 28 are placed on the payout belt 51, and the change is collected and transferred to the change tray 52.

The coin drop means F26 of the overflow mechanism F has two types, movable and fixed, similarly to that of the change hopper mechanism D. The fixed coin dropping means F26b is the same as the fixed coin dropping means D26b,
The two means F26a, F26b are arranged only at the plate material 36, and are arranged at positions near the upper surface of the receiving belt 15 substantially immediately above the overflow belt 53. The movable coin dropping unit F26a is located in front of the fixed coin dropping unit D26b of the change hopper mechanism D in the coin transfer direction, and is paired with the movable coin dropping unit F26.
Reference numeral 6b denotes a pair in front of the movable coin dropping unit D26a of the change hopper mechanism D.

The movable coin dropping means 26a has a change hopper mechanism (corresponding to 1 yen, 5 yen and 10 yen in the embodiment) corresponding to the fixed coin dropping means D26b, and its own solenoid 32 when coin storage is unnecessary. OFF, the shutter plate 31 descends (coin falling state α), and the coin M on the receiving belt 15
The overflow coin drop port 22 from the overflow belt 53
Drop it up.

The fixed coin dropping unit F26b is provided with a change hopper mechanism (corresponding to the movable coin dropping unit D26a) corresponding to the fixed coin dropping unit D50a (in the embodiment, for 50 yen, 100 yen and 500 yen). Since the movable change drop unit D26a is turned on and lifts the shutter plate 31, the coin M passing below the shutter plate 31 is dropped from the overflow drop opening 22 onto the overflow belt 53.

One of the means (in the case of the fixed coin dropping means F26b) is in the same direction as the transfer direction of the overflow belt 53, and the coin M rises and rotates as one of the means (in the case of the fixed coin dropping means F26b) falls from the receiving belt 15 to the overflow belt 53. It is possible to carry out the delivery smoothly without any trouble, but the other means (in the case of the movable coin dropping means F26a, the direction of the transfer of the overflow belt 53 is opposite to that of the overflow belt 53; May rise and rotate, taking a long time to transfer, or remaining on the belt without being able to be transferred.

In FIG. 10, the height 56 from the upper surface of the overflow belt 53 to the upper surface of the receiving belt 15 is set according to the diameter of the coin M.
Experiments have shown that the rise of the coin can be prevented by setting the gap 55 to the lower surface of the coin 15 to be larger than the coin thickness and not more than about one-half the coin diameter.

That is, if the height 56 is larger than the coin diameter, the drop of the coin becomes large, the falling posture and the landing posture of the coin are not constant,
It is difficult to fall down smoothly, and it may lean against the side wall plate 20. If the gap 55 is larger than one half of the coin diameter, the coin will be flipped over and may lean against the side wall plate 20 in some cases. There is. When the height 56 and the gap 55 are adapted to the above conditions, the coins fall from the receiving belt 15 and when one end comes into contact with the overflow belt 53, the coin is received.
Even if it leans, one end of the belt
Is rotated so as to enter the lower side, and is placed on the overflow belt 53 in a flat shape.

Note that the change function and the overflow function can be used in various ways. First, the change hopper 28 is provided with only the remaining amount sensor 47, and the overflow mechanism F is always operated.
All the coins M put into the receiving hopper 3 are put into the overflow tray 54, and when the remaining amount sensor 47 is activated, change coins or put coins are supplied to the change hopper 28 for a timer set time. Secondly, the change hopper 28 is provided with only the full sensor 48, and the coin M is always supplied to the change hopper 28.
When the full sensor 48 is activated, the overflow mechanism F is activated to cause the inserted coin to overflow. Third, by providing the remaining sensor 47 and the full sensor 48, the coins are always supplied to the change hopper 28, and when the remaining sensor 47 is activated, the coins for change are specially supplied. When the full-batch sensor 48 is activated, the overflow mechanism F corresponding to the full-budget change hopper 28 is activated to cause the coins to overflow.

Next, a processing operation and a power transmission system of the coin processor 1 of the embodiment will be described.

For example, when coins in a mixed state which have received a trading value from a customer are put into the receiving hopper 3, this is detected and the motors P1, P2, P3 operate for a certain period of time. The rotating disk 4, the scraping roller 6, and the transfer belt 8 are driven by the operation of the motor P1,
The coins in the receiving hopper 3 are transferred onto the sorting plate 7 one by one at intervals, fall from the coin window W corresponding to each diameter, and the number of coins of each type is detected by the detecting means. Is calculated.

The coin M dropped from the coin window W is guided by the guide plate 13 and the receiving belt driven by the motor P2.
It is transferred flat on the upper surface 15, lifted up to the idler pulley 19, and then transferred horizontally.

When the storage mechanism remains in the change hopper 28 and the overflow mechanism F is not operated (the remaining sensor 47 is operated or the full delivery sensor 48 is not operated), the solenoid 32 of the movable coin dropping means D26a of the change hopper mechanism D is operated. Is off and 50
The coins of yen, 100 yen and 500 yen are dropped and supplied from the receiving belt 15 to the change hopper 28 by the shutter plate 31, and at the same time, the solenoid of the movable coin dropping means F26a of the overflow mechanism F
32 is ON, and the coins of 1 yen, 5 yen and 10 yen pass under the shutter plate 31 and are dropped and supplied from the receiving belt 15 to the change hopper 28 by the plate material 36 of the fixed coin dropping means D26b. You.

When the cash register body compares the trading value with the input amount and calculates the change amount, the motor 29 of the required change hopper mechanism D is operated and the change hopper 28 is operated in order to pay out coins constituting the change amount. The payout board 27 rotates to send out the stored coins onto the payout belt 51, and the payout belt
51 is driven by a motor P3 to collect change coins M and transfer them to a change tray 52.

When the shortage sensor 47 of the change hopper mechanism D is not operating, or when the full sensor 48 is operating, the overflow mechanism F is operated and the solenoid of the movable coin dropping means F26a is operated.
32 turns off, and coins of 1 yen, 5 yen and 10 yen are overflowed from the receiving belt 15 by the shutter plate 31 to the overflow belt.
53, and at the same time, the solenoid 32 of the movable coin dropping means D26a of the change hopper mechanism D is turned on, the shutter plate 31 rises, and coins of 50 yen, 100 yen, and 500 yen passing below the fixed coin drop. Overflow belt 53 by means F26b
And these coins are collected and stored in the overflow tray 54.

(Effects of the Invention) According to the present invention described in detail above, coins M in a mixed state are inserted, sorted by type, stored in the change hopper mechanism D, and a required number of changes are transmitted from the change hopper mechanism D. It is possible to automate the operation of paying out coins and overflowing coins when change storage is unnecessary, saving labor of coin storage and change payout, appropriately processing coins at the time of overflow, and furthermore, each receiving belt 15 A coin dropping means D26 for the change hopper mechanism D and a coin dropping means F26 for the overflow mechanism F are provided on the upper side of the coin hopper mechanism D, and the front side of the coin dropping transfer direction is movable and the front side is fixed, so that coins are stored and stored. It is possible to reliably sort for overflow and to make it simple and compact.

In addition, since a plurality of receiving belts 15 are formed as a pair and a coin drop interval 23 is provided between the two belts, the length of the apparatus can be reduced. The coin dropped from the belt 15 by the coin dropping means F26 is in a direction opposite to the coin transfer direction of the overflow belt 53, but the height 56 between the upper surfaces of both belts 15, 53 is substantially equal to or less than the coin diameter, and both belts 15, Since the gap 55 between the coins 53 is set to be larger than the thickness of the coin and not more than about one-half of the coin diameter, the falling coin rotates and is placed on the overflow belt 53 in a flat shape, and can be placed in a rising state. No coins can be reliably delivered.
