Description

[Detailed Description of the Invention] (a) Technical Field The present invention relates to a money exchange machine that exchanges 10,000 yen bills or 1,000 yen bills into 100-cylindrical coins or 10-cylindrical coins, and particularly relates to a money changer that exchanges a specified number of coins from a cylindrical coin storage tray. The present invention relates to a cylindrical coin discharge device that takes out cylindrical coins.

(b) Prior Art A currency exchange machine generally includes a plurality of stacked cylindrical coin storage trays, and uses a hanger to take out a specified number of cylindrical coins from the cylindrical coin storage tray. Further, a selector is used to select the cylindrical coin storage tray in which the cylindrical coins to be taken out by the hanger are stored, and the cylindrical coin storage tray at the position to which the selector is moved is selected.

In the money changer having the above configuration, the conventional cylindrical coin ejecting device places the cylindrical coin storage trays of frequently used denominations in the upper to middle stages near the cylindrical coin ejecting part, and the trays are arranged in the upper to middle tiers near the cylindrical coin ejecting part. By placing the cylindrical coin storage tray of low denominations on the lower stage away from the ejection section, when processing frequently used denominations, the hanger takes out the cylindrical coins from the cylindrical coin storage tray and lifts them up to the ejection section. I was trying to shorten the processing time by making it shorter.

(c) Problem to be Solved by the Invention However, in order to move the tubular coin storage tray to a position where the hanger can take out the tubular coin storage tray, it is necessary to set the selector to the position of the tubular coin storage tray of the set denomination. If the selector position before setting the denomination is far from the position of the coin storage tray for the set denomination, it may take a long time to move the selector. There was an inconvenience. For example, if the selector is in the lower row before setting the denomination, the upper denomination will be set, or if the selector is in the upper or lower row before setting the denomination, the middle denomination will be set. If set, the time required for the hanger to take out the cylindrical coin from the cylindrical coin storage tray and reach the ejection unit is added to the time required for each time the selector moves to the position of the cylindrical coin storage tray for the set denomination, so the result is However, the processing time for frequently used denominations is not necessarily faster than the processing time for less frequently used denominations, which has the disadvantage of reducing the operating efficiency of the exchange machine.

The purpose of this invention is to store frequently used denominations in the middle and middle stages near the discharge section, and to specify the initial position of the selector before setting the denomination in the middle position. To provide a cylindrical coin discharging device which improves the operating efficiency of a money exchange machine by making the processing time for denominations shorter than the processing time for less frequently used denominations.

(d) Means for Solving the Problems The cylindrical coin ejecting device of the present invention includes a multi-stage cylindrical coin storage tray arranged vertically, a discharge section provided above the cylindrical coin storage tray, and a cylindrical coin discharging device that moves upwardly. A hanger that takes out a specified number of cylindrical coins from a coin storage tray and releases them into a discharge section, and a selector that moves the cylindrical coin storage tray containing the cylindrical coins to be taken out using this hanger to a position where the hanger can grip the coins. When the denomination to be exchanged is set, move the selector to the position of the cylindrical coin storage tray corresponding to that denomination and operate it, then move the hanger to remove the specified cylindrical coin from the cylindrical coin storage tray. A money exchange machine equipped with a control means for taking out coins, wherein the upper and middle stages of the multi-stage cylindrical coin storage trays are configured with trays storing frequently used cylindrical coins, and the lower stage is configured with trays storing less frequently used coins. an initial position detecting means for detecting that the selector is in this position; and an initial position detecting means for detecting that the selector is in this position, and discharging a cylindrical coin of a set denomination. and means for returning the selector to the initial position afterward.

(e) Operation In this invention, when the denomination of the lower row is set, the selector moves downward from the initial position of the middle row, takes out the coin of the denomination stored in the lower row, and then moves the coin past the upper row. and lift it upward to the release position. For this reason, when the lower denomination is set, it takes a long time to take out the coin and lift it to the ejection unit, and it also takes a long time to move the selector to the lower stage, resulting in a long processing time overall. Become. However, since the lower tier coins are used less frequently, this operation is rarely performed.

When the middle denomination is set, the process time becomes very short because the selector movement time added to the time required for the hanger to take out the cylindrical coin from the cylindrical coin storage tray and lift it to the discharge section is short.

In addition, when the upper denomination is set, it is necessary to move the selector, but since it is close to the ejecting part, the time it takes for the hanger to take out the cylindrical coin from the cylindrical coin storage tray and lift it to the ejecting part is shortened, and the processing time is significantly reduced. Becomes shorter. This operation is performed frequently because the middle and upper tiers store cylindrical coins of frequently used denominations.

Therefore, by shortening the processing time for frequently used coins stored in the upper and middle coin storage trays, even if it takes a little longer to take out the coins in the lower row, overall exchange is possible. processing time can be shortened.

(f) Embodiment FIG. 1 is a schematic structural diagram of a cylindrical coin discharging section of a money changer according to an embodiment of the present invention. The cylindrical coin storage tray 1 consists of 10 coins in total, and each tray is tilted and stacked vertically, and the two trays are stacked in order from the bottom.
500 cylindrical coins, 4 trays with 10 cylindrical coins,
The remaining four trays each contain 100 cylindrical coins. The chain 2 is composed of two, and each chain is driven by sprockets 3-6. Sprockets 3-6 receive driving force from a main motor 7 via a clutch. One side of chain 2 connects a total of 14 hangers 8 (8a to 8n) to arrow A.
direction, and the other chain is selector 1
0 in the direction of arrow A or B. The direction of movement of the chain is determined by whether the motor 7 is rotated forward or reverse.

An initial position detector 9 of the selector is mounted on the opposite side of the cylindrical coin storage tray 1 across the chain 2 via a mounting fitting 9a.

Further, a position detection terminal 9b of the selector 10 is attached to the chain 2. The initial position detector 9 detects the detection terminal 9 when the selector 10 is at the fifth position from the bottom of the cylindrical coin storage tray.
It is positioned so that it can face b. Thereby, the initial position of the selector 10 after discharging the tubular coin of the set denomination is specified as the fifth position from the bottom of the tubular coin storage tray. The initial position detector 9 and the position detection terminal 9b constitute the initial position specifying means of the present invention.

When the selector 10 is at the fifth position from the bottom of the cylindrical coin storage tray as shown in the figure, the storage tray moves to the dotted line position in the figure, and in this state the chain 2 that moves the hanger 8 moves in the direction of arrow A. As the process progresses, the cylindrical coins are gripped in order by the hangers 8a to 8n from the tip of the cylindrical coin storage tray. When the three hangers 8a to 8c pass the position of the cylindrical coin storage tray that has been moved forward, a total of three cylindrical coins will be taken out.
When 4 hangers 8a to 8b pass, a total of 4
A cylinder of coins will be taken out. After taking out a predetermined number of cylindrical coins in this way, the cylindrical coin storage tray that had been moved forward is returned to its original position, and the chain is driven to move the hanger again. The coins are sequentially conveyed to the discharge section 11.

FIG. 2 is a diagram showing the operating state of the selector 10. A selector drive bar 13 that can move in the direction of arrow C or D is vertically disposed behind the selector 10 attached to the chain 2a. The selector 10 is formed of a substantially triangular flat plate, and is supported rotatably in the direction of arrow E or F about a pin 10a. A lever 14 is provided in front of the selector 10 and is rotatable around a pin 14a. Further, a projection 1a is formed on the lower surface of the cylindrical coin storage tray 1. With the above configuration, in order to move the selector 10, which is normally in the state shown by the solid line in the figure, to a predetermined position using the chain 2a, and to move the cylindrical coin storage tray in that position forward, move the selector drive bar 13 as indicated by the arrow. Move in direction C to the dotted line position. As a result, the selector 10 also moves in the direction of arrow E around the pin 10a to the dotted line position, kicks up the lever 14, and rotates the lever 14 around the pin 14a to the dotted line position. Normally, one end of the lever 14 locks a protrusion 1a provided on the lower surface of the cylindrical coin storage tray 1, but when the lever 14 rotates to the dotted line position in the figure, the locking state of the protrusion 1a is released. As a result, the cylindrical coin storage tray 1 can be moved in the direction of arrow G.

FIG. 4 is a block diagram of the control section of the cylindrical coin ejecting device. The CPU 15 is connected via an internal bus 21 to an input/output unit 18, a ROM 16 that stores programs that define the operation of the CPU 15, and a RAM 17 that stores current selector positions and various data. Connected to the input/output section 18 are an actuator 20 that operates the operating section of the cylindrical coin discharge device, and an initial position detector 9 that specifies the initial position of the selector before setting the denomination.

Next, the operation of the cylindrical coin ejecting device will be explained with reference to the flowchart of FIG.

Once the denomination is set, step n1 (hereinafter step
ni is simply called ni. ) ~ The denomination set in n3 is determined. If the set denomination is single
Use n4 to n6 to move the selector to the position of the usable cylindrical coin storage tray of the set denomination. Then pull the tray forward with n7~n9, then n10~n12
Take out the coin tube and return the storage tray to its original position with steps n13 to n15. Thereafter, in steps n21 to n23, the removed cylinder coin is lifted to the ejecting section, in n24, the cylinder coin is ejected, and in n25, the selector is returned to the initial position. If the set denominations are multiple and include 500 yen, use n4 to move the selector to the available 500 cylindrical coin storage tray, and press n7→n10→
Go to n13 and check if other denominations are set to n16
Determine by

If the set denomination is not only 500 yen, use n17 to move the selector to the position of a usable 10-cylindrical coin storage tray, simultaneously lift the removed 500-cylindrical coin, and use n18 to determine whether 10 yen is set. If 10 yen is set, n8→n11→
Proceed to n14. After that, use n19 to determine whether 100 yen is set, and if 100 yen is set, use n20 to move the selector to the usable 100 cylindrical coin storage tray and simultaneously lift the 10 cylindrical coin taken out n9 → n12 Proceed as →n15→n23. After that, the cylinder coin is released at n24, and the selector is returned to the initial position at n25. If 10 yen is not set in n18, proceed directly to n19. If 100 yen is not set at n19, proceed to n22, eject the tube coin at n24, and return the selector to the initial position at n25. In the above operation, n25 corresponds to the means of the present invention for returning the selector to the specified initial position after processing the cylinder coin.

Next, the processing time of a tube coin will be explained for each case using the same figure.

When setting denominations, there are three possible combinations: 500 yen only, 10 yen only, and 100 yen only. Also, if multiple denominations are set, 500 yen + 100 yen + 10 yen, 500 yen + 10 yen, and 500 yen
There are four possible options: yen + 100 yen and 100 yen + 10 yen.
The time required for n4, n5, and n6 is TA3, TA1, and
Let TA2 be the time required for n21, n22, and n23 as TB3,
Assuming TB1 and TB2, the time required for n17 is TB3−
The time required for TB1 and n20 is TB1 - TB2. If the set denomination is only 500 yen, the processing time required is TA3 + TB3, if only 10 yen is set, the processing time is TA1 + TB1,
If it is only 100 yen, it will be TA2 + TB2.

When all denominations are set and 500 yen and 100 yen
The processing time required when yen is set is TA3+
(TB3 - TB1) + (TB1 - TB2) + TB2, which is the same as when TA3 + TB3 is only 500 yen. The processing time required when the set denominations are 500 yen and 10 yen is TA3 + (TB3 - TB1) + TB1, which is calculated as TA3 + TB3, which is the same as in the case of only 500 yen. The processing time required when 10 yen and 100 yen are set is TA1 + (TB1 - TB2)
+TB2, which is the same as TA1+TB1 and only 10 yen.

As described above, there are three types of processing time caused by different set denominations when only one set denomination is used. The initial position of the selector is the position of the 10 cylindrical coin storage tray, so TA1 is the same as TA3 and
Shorter than TA2. In addition, there is a 100 cylindrical coin storage tray on the upper level and a 10 cylindrical coin storage tray on the middle level.
By placing the 500 cylindrical coin storage tray at the bottom, TB2 is shorter than TB1, and TB1 is shorter than TB3. For these reasons, the processing times TA1+TB1 and TA2+TB2 when the set denomination is only 10 yen and only 100 yen are shorter than the processing time TA3+TB3 when the set denomination is only 500 yen.

As described above, according to this embodiment, the frequently used denominations stored in the upper and middle tiers are
100 yen and 10 yen cylinder coins, 500 yen coins that are rarely used
It can be released in a shorter period of time compared to cylindrical coins.

(g) Effects of the Invention According to this invention, by storing frequently used cylindrical coins in the upper and middle tiers and setting the initial position of the selector in the middle tier, the discharging time of frequently used cylindrical coins can be shortened. Can be shortened. The overall exchange time can be shortened. As a result, it is possible to improve the operating efficiency of the money exchange machine, and it is also possible to improve the service to customers.
