Description

  The present invention relates to a coin processing device, and more particularly to a coin processing device used in a vending machine.

  Generally, vending machines are operated with a certain amount of change coins as reserves. Insufficient change leads to a direct decline in sales due to the inability to sell the product. On the other hand, simply laying the reserve does not generate profit. In addition, since there is a possibility that the reserve money will be stolen, the administrator of the vending machine wants to operate with as little reserve money as possible.

  As a function of a coin processing device for change operation of a conventional vending machine, a change management function for efficiently collecting coins is known. As an example, there is one that can automatically pay out the change that has been retained in excess of the set number of change at the time of change collection to a certain set number of change and leave the change of the desired number (for example, Patent Document 1). reference).

Alternatively, the number of coins that can be stored in the change-holding cylinder and the initial number of sheets that can be stored in the change-holding cylinder are arbitrarily set, and the maximum number of coins that can be stored in the change-holding cylinder The coins are led to a safe, and when the change is collected, an initial reserved number is left in the change-holding cylinder, and the remaining coins in the change-holding cylinder are paid out and collected (for example, Patent Document 2).
Japanese Patent Laid-Open No. 3-31985 (FIG. 1) JP-A-5-290238 (paragraph numbers [0006] to [0007], FIG. 1)

  However, it is a function for collecting change money, and it does not optimize the number of change itself. It depends on the vending machine administrator's intuition and the remaining amount of change at the time of change collection. I was judging the amount of change I think was necessary in the meantime. For this reason, the vending machine still has a problem that the change of money may occur or the change may be excessive.

  The present invention has been made in view of the above points, and provides a coin processing device that can be logically grasped in a coin processing device without relying on intuition on the status of change hold such as the occurrence of excess or deficiency of change. The purpose is to do.

In the present invention, in order to solve the above problem, a coin identifying means for identifying the denomination of the inserted coin, and a distributing means for distributing the coin identified by the coin identifying means to the change tube corresponding to each denomination. A coin detecting means for detecting the insertion of coins into the change tubes, and coins being dispensed from the change tubes respectively provided for the change tubes. a payout coin detection means for detecting the the insertion number of coins detected by the deposited coin detecting means, calculates a payout number of more sensed coin on the payout coin detection means, the payout number and the insertion number The change hold status calculation means for calculating the change hold status of each change tube from the above, and the change calculated by the change hold status calculation means Comprising a exact change pending status displaying means for displaying the exact change pending status to the outside, the, the exact change pending status calculating means, in relation to the insertion number and the payout number, the number of coins to be held in the respective exact change tube A change situation map in which an optimal change optimal area, a change shortage area when there are fewer coins than the change optimal area, and a change change excess area when there are more coins than the change optimal area, With reference to the change situation map based on the current inserted number and the paid-out number, the inserted number and the paid-out number are each equal to or greater than a predetermined number that can be used to evaluate the tendency of excess or deficiency of change. , as the change due pending status, change due optimal, providing a coin processing apparatus is characterized by calculating the exact change shortage and exact change over It is.

  In such a coin processing device, the change hold status of each change tube is calculated from the number of coins inserted into each change tube and the number of coins discharged from each change tube, and is displayed externally. .

  According to the coin processing apparatus of the present invention, the change hold status of each change tube is displayed to the outside based on the number of coins inserted and paid out. For this reason, by confirming the change suspension status, it is possible to objectively grasp the occurrence of change of change in each change tube and the extent of change change. As a result, it is possible to operate change more appropriately.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Moreover, as shown in FIG. 2, the coin processing apparatus 1 has the coin receiving part 12 which receives the coin thrown into the upper part of a figure, and has the coin identification part 13 which determines the kind of coin thrown into the lower part. I have. A gate G1 for sorting the received coins according to whether they are 100 yen and 500 yen or 10 yen and 50 yen is provided below the coin identifying unit 13. Furthermore, at the lower part of the gate G1, a gate G2R for sorting whether the coins distributed as 10 yen or 50 yen by the gate G1 are collected into the safe, and a coin not collected into the safe are used as a 10 yen tube or 50 A gate G3R for distributing the circular tubes is provided.

  Furthermore, a gate G2L is provided below the gate G1 to distribute coins distributed as 100 yen or 500 yen by the gate G1 to the 100 yen path 14 or 500 yen path 15.

  Further, coin insertion detection sensors 16a to 16d are provided in the vicinity of the upper end of each change tube of the cassette tube 11, and this is detected when a coin is inserted into each change tube. Further, a change dispensing detection sensor (not shown) is provided in the vicinity of the lower end of each change tube of the cassette tube 11, and this is detected when a coin is paid out from each change tube. In addition, a microcomputer (hereinafter referred to as “microcomputer”) for operating the gates, levers, and sensors is built in the back of the coin processing device 1.

FIG. 3 is a block diagram showing the electrical configuration of the control circuit centered on the microcomputer in the vending machine.
The microcomputer 20 includes a CPU (Central Processing Unit) 201 that performs predetermined arithmetic processing, a ROM (Read Only Memory) 202 in which various numerical values and programs are written in advance, and numerical values and flags of arithmetic processes are written in predetermined regions. A RAM (Random Access Memory) 203, an EEPROM (Electrically Erasable Programmable Read-only Memory) 204 which is a non-volatile memory, an I / O (Input / Output) interface 205 for inputting / outputting various digital signals, and these devices Each of the bus lines 206 is connected to each other. The processing shown in the flowchart described below is executed based on a control program written in advance in the ROM 202.

  The microcomputer 20 receives detection signals from the sensor group 17 including the coin insertion detection sensors 16a to 16d and the change payout detection sensor, and the CPU 201 executes processing based on these signals. The microcomputer 20 is configured to be capable of serial communication with the microcomputer on the vending machine side via the I / O interface 205.

Next, a method for calculating the change hold status according to the present embodiment will be described.
FIG. 4 is a change situation map used for calculation processing of the change hold situation described later.
In the coin processing device 1, the change hold status is determined from the relationship between the number of coins inserted and the number of change dispensed for each change tube.

  This change situation map includes an optimal change area where the number of coins held in each change tube is optimal, and an insufficient change area when there are fewer coins than the optimal area. An excessive change area when there are more coins than the optimal area is set in advance.

  In addition, areas where the number of coins inserted and the number of coins to be paid out are each equal to or less than a predetermined value are not calculated. That is, in order to grasp the tendency of change in excess or deficiency, a certain number of inputs and withdrawals are required, and therefore it is necessary that the number of coins inserted or the number of changes paid out has reached a certain level. For this reason, if the number of coins inserted or the number of changes paid out does not reach a certain level, the data is insufficient, so that accurate statistics are not taken and are excluded from calculation.

  For example, suppose that a certain vending machine has an average of 60 sales per day, and an average of two sheets are inserted and paid out in one sale. As a rule of thumb, if the period during which the change in change can be grasped is about one week, the total number of inserted and paid out has reached 840 in calculation. For this reason, the average number of coins to be denominated and the number of coins to be paid out are about 200, so if you want to know the change situation, you should set the minimum number of coins to be inserted and the amount of coins to be paid out to about 200. . In this example, at least one of the coin input number and the change payout number is 200 as the minimum number for grasping the change situation.

  Further, a change shortage area and a change change excess area are set on both sides of a change optimal area outside the non-calculation area. The change shortage area is set as an area where the change amount of change is larger than a certain ratio compared to the number of coins inserted, and if the change is in this area, it is determined that the change is insufficient.

  On the other hand, the change excess area is set as an area where the number of coins inserted is greater than a certain ratio compared to the change payout number, and if the change is in this area, it is determined that the change is excessive. In the change optimal area, which is between the change shortage area and the change change excess area, the difference between the number of coins inserted and the number of change paid out is within a certain range, and if the change is in this area, it is determined that the change is optimal. .

  Here, it is assumed that the above-mentioned fixed ratio is 10%, and that the change is insufficient when the number of payouts is 10% or more than the number of input sheets, and that the change is excessive when the number of input is 10% or more than the number of payouts.

Next, the change status display method of the present embodiment will be described.
5 to 7 are explanatory diagrams showing display examples of the change hold status, FIG. 5 is a view showing a display example in the change status display mode, and FIG. 6 is a display example in the change history display mode. FIG. 7 is a diagram showing a display example in the change time display mode.

  In the coin processing apparatus 1, the input / output panel 10 is used not only for displaying the coin acceptance accuracy but also for displaying the change hold status calculated as described above. That is, as shown in FIG. 5, in a normal use, the denomination switch 101 written as 100 or 500 on the input / output panel 10 is used as a start switch for the change collection function.

  Further, the accuracy lamp 102 for each denomination displays the current coin acceptance accuracy of the coin processing device 1 by lighting, blinking, or the like. Note that the coin acceptance accuracy is usually a standard, and when a crime with a false coin occurs, the accuracy is increased. Various functions are set using the start / decision and setting / confirmation switches 103 and 104 together, for example, the setting of the above-described acceptance accuracy.

  On the other hand, the change hold status is displayed in three display modes: a change status display mode, a change change history display mode, and a change time display mode, which are displayed by changing the display mode of the accuracy lamp 102. The transition from the normal display form to the display of the change suspension status is performed by detecting that the cassette tube 11 has been removed by the administrator and the inspection switch 105 has been pressed.

  Each display mode is switched by pressing the inspection switch 105 of the input / output panel 10. The right side of the figure shows the light emission pattern of LED (Light Emitting Diode) and its meaning in that mode.

  There are four types of LED emission patterns in the change status display mode. There are two types of blinking, and the blinking speed is set to be remarkably different so that the two types are blinking. For example, the blinking cycle of fast blinking is set to 200 ms, and the blinking cycle of slow blinking is set to 1 s.

  Here, when the LED is lit, it indicates that the change is optimal, and when it is blinking rapidly, it indicates that the change is insufficient. Further, when it is blinking slowly, it indicates that there is an excess of change, and when it is turned off, it indicates that it is not subject to calculation.

  In the case of the display example in FIG. 5, 500 yen is not lit and not subject to calculation, 100 yen is lit and determined to be appropriate for change, 50 yen is blinking slowly and change is excessive. It has been judged that 10 yen blinks rapidly and it has been judged that change is insufficient.

  In the present embodiment, when returning from the change mode display mode to the normal display mode, the change tube is attached. For this reason, when the administrator ends the change status display mode immediately after confirming the change status display mode, the change tube is attached to shift to the normal display mode.

  Further, when clearing the data in this mode, the data is cleared by pressing the inspection switch 105 for a long time. It should be noted that the mode change is made from the change status display mode to the change history display mode by pressing the inspection switch 105.

  As shown in FIG. 6, there are three types of LED display patterns in the change history display mode. When the LED is lit, it indicates that no change has occurred. When the LED is flashing rapidly, it indicates that a change has occurred. It shows that it is outside.

  In the case of the display example of FIG. 6, 500 yen is not lit, it is not subject to calculation, 100 yen and 10 yen are flashing rapidly, a change has occurred, and 50 yen is lit. This means that no change was generated.

  In the present embodiment, when returning from the change mode display mode to the normal display mode, the change tube is attached. For this reason, when the administrator ends immediately after confirming the change history display mode, the change tube is attached to shift to the normal display mode.

  Further, when clearing the data in this mode, the data is cleared by pressing the inspection switch 105 for a long time. Note that the mode change is made from the change history display mode to the change time display mode when the inspection switch 105 is pressed.

  As shown in FIG. 7, in the change time display mode, the LED display patterns include four types of display patterns as in the change status display mode of FIG. When the LED is lit, it indicates that no change has occurred, and when it is flashing rapidly, it indicates that change has occurred for a long time. In addition, when blinking slowly, it indicates that a change of cash has occurred for a short time, and when it is turned off, it indicates that it is not subject to calculation.

  In the case of the display example in FIG. 7, 500 yen is not lit and is not subject to calculation, 100 yen is flashing slowly and a change of change occurs for a short time, 50 yen is lit and change of change is not That it did not occur, 10 yen flashes quickly, indicating that a change of cash has occurred for a long time.

  For example, if the change time is long or short, it is judged that the change has occurred for a long time if the change time is over half of the operating time of the vending machine. If it is less than that, it is determined that the change has occurred for a short time.

  In the present embodiment, the change from the change mode display mode to the normal display mode is performed by attaching the change tube or pressing the check switch 105. For this reason, when the administrator returns from the change time display mode to the normal display mode, the change is made to the normal display mode by attaching a change tube or by long pressing the check switch 105.

  Further, when clearing the data in this mode, the data is cleared by pressing the inspection switch 105 for a long time. When the data in this mode is cleared, the processing for displaying the change hold status is terminated, and the normal display mode is entered. In this mode, when the inspection switch 105 is pressed, the mode returns to the change status display mode and the above process is repeated.

Next, the flow of the change hold status calculation and display process of the present embodiment will be described.
FIG. 8 is a flowchart showing a procedure for calculating the change situation executed by the CPU described above. In the following, the process illustrated in FIG. 8 will be described in order of step number.

  [Step S101] Based on the output signals of the coin insertion detection sensors 16a to 16d, it is determined whether or not a coin has been inserted into each change tube. If it is determined that there has been an input, the process proceeds to step S102. If it is determined that there has not been an input, the process proceeds to step S103.

  [Step S102] In order to count the number of coins inserted, a coin insertion counter preset in a predetermined area on the RAM 203 is incremented by 1, and the process proceeds to step S103.

  [Step S103] Based on the output signal of the change payout detection sensor, it is determined whether or not a coin has been paid out from each change tube. If it is determined that there has been a payout, the process proceeds to step S104. If it is determined that there has not been a payout, the process proceeds to step S105.

  [Step S104] In order to count the change payout number, a change payout counter preset in a predetermined area on the RAM 203 is incremented by 1, and the process proceeds to step S105.

  [Step S105] It is determined whether or not the number of coins to be inserted is 200 or more for which the change hold status is to be calculated. If the number of inserted coins is 200 or more, the process proceeds to step S106, and if it is less than 200, the process proceeds to step S111.

  [Step S106] It is determined whether or not the number of coins inserted is 10% or more greater than the number of change dispensed. If the number of coins inserted is 10% or more, the process proceeds to step S107. If the difference in the number is less than 10%, the process proceeds to step S108.

[Step S107] It is determined that the change is excessive.
[Step S108] It is determined whether or not the change payout number is 10% or more greater than the number of coins inserted. If the change amount of change is 10% or more, the process proceeds to step S109, and if the difference is less than 10%, the process proceeds to step S110.

[Step S109] It is determined that change is insufficient.
[Step S110] It is determined that the change is optimal.
[Step S111] Since it is determined in step S105 that the number of coins to be inserted is less than 200, it is determined here whether or not the number of coins to be paid out is 200 or more. If the change amount is 200 or more, the process proceeds to step S106, and if it is less than 200, the process proceeds to step S112.

  [Step S112] If both the number of coins inserted and the number of coins to be paid out are 200 or less, it is assumed that the number of parameters is too small as a judgment material for observing a certain tendency of the number of coins to be inserted and the number of coins to be paid out. Not subject to calculation.

FIG. 9 is a flowchart showing the procedure of change change detection processing executed by the CPU described above. In the following, the process illustrated in FIG. 9 will be described in order of step number.
[Step S201] It is confirmed whether or not a change dispensing start flag is set in a predetermined area on the RAM 203. If the change dispensing start flag is set, the process proceeds to step S204. If the change dispensing start flag is not set, the process proceeds to step S202. The change dispensing start flag is set on the RAM 203 when the change dispensing starts.

  [Step S202] It is determined whether or not change dispensing has been started. This determination is made based on a change payout command output from the vending machine microcomputer after the predetermined sales process is completed. If change has been started, the process proceeds to step S203, and if change has not been started, the process proceeds to step S208.

  [Step S203] If the change payout start flag is not set when the change payout is started, the change payout start flag is set and then the change payout is started.

  [Step S204] It is determined whether or not the change has been paid out. This determination is made by detecting by the change payout detection sensor that the prescribed number has been paid out. If the change has been paid out, the process proceeds to step S205. If the change has not been paid out, that is, if the change is being paid out, the process proceeds to step S208.

[Step S205] Since the change payout has been completed, the change payout start flag is cleared.
[Step S206] It is determined whether or not the current number of change is less than 10. That is, in the present embodiment, it is determined that the change is out when the number of coins held in each change tube is smaller than a predetermined number set in advance. Here, the reference number is set to 10. If the current change number is less than 10, the process proceeds to step S207. If the current change number is 10 or more, the process proceeds to step S208.

  [Step S207] When the change amount is less than 10 by paying out change, the change occurrence counter is incremented by 1 in a predetermined area on the RAM 203 in advance.

  [Step S208] It is determined whether or not the current change number is less than ten. If the current change number is less than 10, the process proceeds to step S209. If the current change number is 10 or more, the process ends.

[Step S209] When the current number of change is less than 10, the change counter occurrence time count counter previously set in a predetermined area on the RAM 203 is incremented by one.
10 and 11 are flowcharts showing the procedure of the change status display process executed by the CPU described above. Hereinafter, the processing illustrated in FIGS. 10 and 11 will be described along the steps.

  [Step S301] In order to confirm the change of the coin processing apparatus 1, it is determined whether or not the cassette tube 11 containing the change has been removed by the administrator. If the cassette tube 11 has been removed, the process proceeds to step S302. If the cassette tube 11 has not been removed, the process proceeds to step S303. This determination is made by a sensor.

  [Step S302] It is determined whether or not the inspection switch 105 of the input / output panel 10 of the coin processing apparatus 1 is pressed. Various change situations are displayed using the display device of the existing input / output panel 10. If the inspection switch 105 has been pressed, the process proceeds to step S304. If the inspection switch 105 has not been pressed, the process proceeds to step S303.

  [Step S303] When at least one of the removal of the cassette tube 11 and the pressing of the inspection switch 105 is not performed, a normal display process of the input / output panel 10 is performed.

  [Step S304] When the cassette tube 11 is removed and the inspection switch 105 is pressed, the display mode is switched from the normal display mode to the change status display mode. This change status display mode is a mode for displaying the result of the processing shown in the flowchart of FIG. 8, and it is possible to know whether the change is excessive, insufficient or optimal.

  [Step S305] Since it is set to mount the cassette tube 11 as a condition for ending the display of the change status, it is determined whether or not this ending condition is satisfied. If the end condition is satisfied, the process ends. If not, the process proceeds to step S306.

[Step S306] If the inspection switch 105 is pressed for a long time without performing an operation that satisfies the end condition by the administrator, the process proceeds to step S307.
[Step S307] If the check switch 105 is pressed for a long time while the change status is displayed, the number of coins inserted and changed in the RAM 203 in steps S102 and S104 of the flowchart shown in FIG. 8 is cleared. To do. When the recorded information is cleared, the process proceeds to step S309.

[Step S308] When the inspection switch 105 is pressed, the process proceeds to Step S309.
[Step S309] When the inspection switch 105 is pressed in the change status display mode, the mode is switched to the change history display mode and the change history is displayed. This change history display mode is a mode for displaying a part of the result of the processing shown in the flowchart of FIG. 9, and it is possible to know whether or not a change has occurred.

[Step S310] Similar to step S305 described above, when an operation that satisfies a certain predetermined end condition is performed, the process ends.
[Step S311] If the check switch is pressed for a long time without an operation satisfying the end condition, the process proceeds to step S312.

[Step S312] When the check switch is pressed for a long time in the change history display mode, the number of change occurrences is cleared and the process proceeds to step S314.
[Step S313] When the inspection switch 105 is pressed, the process proceeds to Step S314.

  [Step S314] When the check switch is pressed in the change history display mode, the change time display mode is displayed and the change time is displayed. This change time display mode is a mode for displaying a part of the result of the processing shown in the flowchart of FIG. 9, and when the change has occurred, it is possible to know how much time change has occurred. it can.

[Step S315] Similar to step S305 and step S310, when an operation that satisfies a certain end condition is performed, the process is terminated.
[Step S316] If the check switch is pressed for a long time without performing an operation that satisfies the end condition, the process proceeds to Step S317.

[Step S317] When the check switch is pressed for a long time in the change time display mode, the change occurrence time is cleared and the process ends.
[Step S318] When the inspection switch is pressed, the process proceeds to Step S304, and the change status display mode is returned.

  By knowing the results shown in each of the display modes described above, if it is determined that the amount of change is excessive, it is possible to operate with a reduced amount of change, and that the change is insufficient. If it is judged, it is possible to increase the change and operate it so that the sales opportunity of the product is not missed due to the change of change.

  In addition, if a change of cash has occurred, it will be possible to prevent the change from being lost by increasing the number of coins of the denomination so that the sales opportunity of the product will not be missed by the change of change. .

  Furthermore, with respect to denominations that have been out of change for a long time, it is possible to avoid missing sales opportunities for goods due to out of change, especially by replenishing extra coins for change. become.

  The display examples shown in FIGS. 5 to 7 are merely examples. For example, if a 7-segment display or a liquid crystal display is provided, the number of coins inserted or the number of changes paid out can be displayed on the display. Alternatively, the change-out time and the number of change-out occurrences may be displayed.

  Further, the information for displaying the change hold status may be individually cleared as described above, or may be erased all at once. Also, under what conditions the end condition for ending the processing from the display mode may be set, for example, by leaving it unoperated for 30 seconds, or operating the return lever.

  In addition, it is determined based on the convenience of the administrator and the nature of the vending machine whether to determine whether the change is insufficient, excessive or optimal, and whether the change is out of time or short. If the user changes the setting during operation, data that is easier to manage and operate can be displayed, and the operation with the appropriate amount of change can be helped.

  Although FIG. 9 is a flowchart for detecting a change of change, the change of full change detection for detecting the number of times and the time when the change is full in the change tube of each denomination and overflowing is also the flowchart of FIG. The same processing can be detected by using the full sensor of each change tube, and the number of times of fullness can be detected as the number of occurrences of fullness, and the time of fullness can be detected as the time of occurrence of fullness.

  If this result is displayed using the input / output panel 10 in the same way as the result of the change detection process, if the full time seems to be long, the change can be further reduced for operation. Flexible change operation becomes possible.
