Description

[Detailed explanation of the invention] (a) Technical field This invention relates to a money changer that exchanges 10,000 yen bills or 1,000 yen bills into 100 cylindrical coins or 50 cylindrical coins. The present invention relates to a cylindrical coin ejection unit control device for taking out cylindrical coins.

(b) Prior Art and Its Disadvantages Currency exchange machines are generally equipped with a plurality of stacked cylindrical coin storage trays, and a hanger is used to take out a designated 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 coin to be taken out is stored using this hanger, 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 unit control device controls the travel distance of the selector from the reference position to one tray level, as described in Utility Model Application Publication No. 54-45600 Microfilm. The length was measured by counting the number of times the length was fed, and the position of the selector was detected from the measurement results. However, since the position of the selector was detected by counting the number of times the selector was fed out from the reference position, there was an inconvenience that if the means for counting the number of feeds malfunctioned, the selector would not be set at the correct position. . In this case, if all the cylindrical coin storage trays are of the same denomination, no problem will actually occur, but if trays containing multiple denominations are stacked, cylindrical coins of the wrong denomination may be ejected. As a result, there was a problem in which financial claims were generated in transactions.

(c) Purpose of the invention The purpose of this invention is to eliminate the above-mentioned drawbacks, and by double detecting the position of the selector, even if the cylindrical coin storage tray is structured to store multiple types of denominations, the selector can To provide a cylindrical coin discharge unit control device that can almost certainly detect an error state when an error occurs in tray selection.

(d) Means for Achieving the Purpose This invention consists of cylindrical coin storage trays stacked in multiple tiers, and a system that allows the tray to be moved to the position of any one of the plurality of cylindrical coin storage trays. A changer having a selector for selecting, the selector position detection for detecting the position of the selector by measuring the moving distance of the selector from a reference position by multiplying the number of times of feeding for the length of one bullet. means for generating absolute position information of the selector in response to movement of the selector; absolute position detecting means for reading this absolute position information; and the absolute position detected by the absolute position detecting means and the selector position detecting means. The present invention is characterized in that it is provided with a comparison means for comparing the detected selector position with the selector position detected by the comparison means, and a means for executing the subsequent cylinder coin discharging process only when the comparison means detects a coincidence between both positions.

(e) Functions and Effects With the above configuration, in this device, when the selector moves to the target tray for ejecting coins, the selector position detection means detects the selector by counting the number of times the selector is fed. In addition to detecting the position, the absolute position detection means also detects the absolute position of the selector by reading the absolute position information. These selector positions and absolute positions are compared and only when they match, it is assumed that accurate selector movement has been performed and the cylinder coin is ejected.

By operating as described above, according to this invention, even if the absolute position detection means malfunctions, as well as if the count of the number of feeds of the selector is incorrect for some reason, the subsequent coin ejection process can be performed. Can be prohibited. In this way, since the selector position is checked twice by both detection means, there is an advantage that the probability of a monetary claim occurring can be reduced to almost zero.

(e) Embodiment FIG. 1 is a schematic diagram of the internal structure of a money changer that is an embodiment of this invention.

In the figure, 1 is the exchange machine main body, and 2 is a cylindrical coin storage tray stacked in multiple stages. The cylindrical coin storage tray 2 is composed of trays classified by denominations a, b, and c. Tray a stores 500 cylindrical coins, tray b stores 50 cylindrical coins, and tray c stores 100 cylindrical coins. In front of the cylindrical coin storage tray 2, a belt 5 is arranged vertically between pulleys 3 and 4. pulley 3
is connected to a motor (not shown). The belt 5 moves the selector 6 up and down. A tray lock 7 is attached to each cylindrical coin storage tray 2, and the cylindrical coin storage tray 2 is moved forward by the cooperation between the tray lock 7 and the selector 6. In the state shown in FIG. The tray lock 7 attached to the fourth tray 2d is swung clockwise by the selector 6, thereby moving the fourth tray 2d forward. In addition, in front of the selector 6, there is a hard lever 8 in the vertical direction.
is provided, and by moving the kicker lever 8 to the right, the selector 6 is rotated counterclockwise, thereby making it possible to swing the trailer lock 7 clockwise. From the above configuration, the cylindrical coin storage tray located at the position of the selector 6 can be selected.

A lever 9 is attached to the belt 5, and when facing the lever 9 further upward,
A sensor 10 that turns on is attached. The position of the lever 9 is set so that when the lever 9 comes to the position of the sensor 10, the selector 6 comes to the lowest position. This lever 9 is the sensor 10
The position of the selector 6 when it reaches the position becomes the reference position.

A cam 11 is connected to the pulley 4.
This cam 11 rotates once when the selector 6 is moved by the length of one tray by the drive of the belt 5. There is a notch 1 in a part of the periphery of the cam 11.
1a is formed, and the sensor 1 is located close to the cam 11.
2 are arranged. With this sensor 12,
When the selector 6 is moving, it is possible to count the number of times the selector is moved for the length of one tray. An encoder plate 13 is further connected to the pulley 4 by a belt 14. Encoder plate 13
Slits 13a serving as codes representing absolute position information of the selector 6 are formed at regular intervals around the selector 6. Sensor 15 detects this slit 13a. In this embodiment, the encoder plate 13 constitutes means for generating absolute position information of the selector 6,
The sensor 15 constitutes absolute position detection means for detecting the absolute position information.

Next, a description will be given of a control device for the cylinder coin discharging section of the money exchange machine.

FIG. 2 is a block diagram of the cylindrical coin discharger control device.

The CPU 20 is connected to the CPU via the system bus 21.
Record the program that defines 20 operations.
A ROM 22, a RAM 23 for storing positions for setting the selector 6 and outputs of the sensors 12 and 15, and an I/O port 24 are connected. I/O port
The motor 24 receives detection data from the sensors 10, 12, and 15, and also outputs a drive signal for the motor 16.

FIG. 3 is a partial configuration diagram of the RAM 23. As shown in FIG.
Area MA stores the set position N of selector 6. This value N is the position of the cylindrical coin storage tray in which the exchange denomination specified by the customer is stored. A detection code by the sensor 15 is stored in the area MB. The area MC constitutes a counter CTR and counts the output pulses of the sensor 12. The counter CTR constitutes means for counting the number of times the selector 6 is fed from the reference position to the length of one tray.

Next, the operation of the control device will be explained with reference to FIG. FIG. 4 is a flowchart showing the operation of the control device.

First, the customer deposits banknotes into a banknote slot (not shown), and when the setting of the denomination and number of banknotes to be exchanged is completed, step n1 (hereinafter referred to as step ni is simply ni) is completed.
), the tray storing the cylindrical coin of the denomination to be ejected is searched, and the tray position, that is, the selector position N corresponding to the tray position is set in the area MA. Next, the counter CTR is cleared (n2). Next, the motor 16 is driven, and the belt 5 moves the selector 6 upward from the reference position, and each time the sensor 12 turns on, the counter
CTR is incremented by 1, and the selector movement is continued until the count value of counter CTR matches N (n3 to n6). At the stage when N=CTR, the selector 6 remains at the correct position as long as the cam 11 and the selector moving mechanism are working normally. Next, proceed from n6 to n7, call the position code C, which is the absolute position information of the selector 6, from the sensor 15 and set it in area MB, and then in n8, read the position code C called at n7 and the counter.
Compare with CTR count value. If they do not match, the process advances to N9 and error processing is performed. If they match, the lever 8 is moved to the right to pull out the tray (n8'), and then the selector is returned to the reference position (down: n10). Whether the selector 6 has returned to the reference position is determined by whether the sensor 10 is turned on (n11). After this operation, the CPU 20 determines that it is possible to withdraw money, moves a hanger (not shown) upward, and takes out the cylinder coin from the tip of the tray moved forward by the selector 6 and releases it into the coin discharge section (n12). .

Through the above operation, the selector position obtained by the counter CTR is compared with the absolute position of the selector 6 obtained directly from the sensor 15, and only when both positions match as a result of the comparison, the subsequent cylinder coin is ejected. Processing can be carried out.
