Description
SPECIFICATION
Vending Machine Control Systems
The present invention relates to a system for
controlling operation of automatic vending
machines, coin machines and the like.
Recently various kinds of vending machines
and coin machines such as coin-operated washing machines, coin-operated game machines
have been widely developed and used. In the automatic vending machines several kinds of controlling or managing systems have been developed. In one system a number of vending
machines are arranged at different locations and a service man generally called as routeman makes the round of his assigned block to gather various kinds data representing the operation of machines. In addition to this in the vending
machines the routeman has to supplement new products or articles to be vended and also has to collect coins inserted in the machines. However this system has a serious drawback that various kinds of troubles might occur between the routemen and a person who manages the routemen.This is due to the fact that the machines do not supply mechanically any data for representing the operation of machines, but only have indicators which display the numbers of products which have been vended, and thus the routemen must book these indicated numbers on notebooks. During this writing operation careless mistakes and fraudulent booking might occur.
Further the amount of data which can be gathered by the manual booking of routement is limited to certain extent. But in order to manage or control the whole machines in a more precise and effective manner it is preferable to collect much more data.
Summary of the Invention

Description of the Preferred Embodiments
Fig. 1 is a schematic view showing a whole system for controlling and managing a number of automatic vending machines according to the invention. According to the invention each of control devices 1-1, 1-2... are provided in respective machines. In the drawing only two control devices are shown and vending machines in which these control devices are installed are not shown for the sake of simpiicity. Each of the control devices 1-1, 1-2... has a connector which is connected to one or more signal generators of the respective machines through cables 2-1,2-2... so as to receive data signals representing vending operation of the related machine.If the vending machines can vend a plurality of different kinds of products, a plurality of data signal generators are provided in the machine. Then vend signals for different kinds of products have to be received separately from each other.
As will be explained in detail later, the control device 1-1, 1-2... comprises a manipulating unit, a printing unit, an external power unit, an internal battery and a micro-computer. To the control devices 1-1,1-2... isconnectableaprogram setter 3 for presetting set signals such as vend prices, machine number and other items. The program setter 3 is solely handled by a chief routeman or a manager so that general routemen cannot change important items such as vend prices. The control device memorizes the set signals as well as the vend signals. By suitably operating the manipulating unit including a test button, a print button, a clear button and a stop button, the data signals and information signals can be selectively read out in various modes.In the present embodiment the printing units of the control devices 1-1, 1-2... print out the data signals together with the information signals on tapes 5-1, 5-2... The routeman collects these tapes 5-1,5-2... having the necessary signals printed thereon and files them in a notebook 6.
When the whole system is large and a great number of machines are arranged in a very wide region, the machines are grouped into several blooks and each blook is taken care of by a respective routeman who carries his own notebook 6 and/or recorder 4. The recorder 4 can be connected to the control devices 1-1, 1-2...
and the data and information signals stored therein can be transferred to the recorder 4 in a very short time.
For this purpose the recorder4 comprises a memory unit. The recorders 4-1, 4-2... are brought by the routemen to a data terminal 7 and the data and information signals stored in the recorders are read out and transmitted by means of a sound coupler 8 to a central computer system 9. Alternatively, these signals may be supplied from the data terminal to a tape converter 10 to form converted tapes 11-1, 11-2, 11-3 . . . Then these tapes may be transported to the central computer system 9. In this manner the central computer system 9 can collect the data and information signals from the control devices 1-1, 1-2... installed in the vending machines on locations in a very accurate and efficient manner.
According to the invention since it is unnecessary for routemen to book the vend data at each vending machine, any possible mistake and fraudulent booking can be completely avoided.
The central computer system 9 can process the transferred data and information signals from the control devices 1-1, 1-2... to calculate various
useful sales data such as a total number of sales,
a total accounts of sales, a total number of sales
per product, a total account of sales per product, a
total sales account per machine, an average
number of sales per machine, an average account of sales per machine, etc.
Fig. 2 is a perspective view showing an outer
appearance of the control device 1. As explained above the control device comprises the printer including a roll 21 of tape having a length of 33m and a width of 8mm, a pressure roller 22, a rotating ball having letters 1, 2, 3...9, C, T, , ., :, 0 and Setter size is 1.7 mm wide x 2.7mm long), a solenoid and pulse motor for driving the rotating ball and stopping it at a desired letter position. It is a matter of fact that any other type of printer may be equally used.The control device 1 further comprises a print button 23, a clear button 24, a test button 25 and a stop button 26, a connector 27 for connecting the program setter 3 and the recorder 4, a test lamp 28 which is lighted on when the control device 1 is in a test condition, and a status lamp 29 which is turned on when the control device 1 is in a normal operating condition. These lamps 28 and 29 may be constituted by light emitting diodes.
Fig. 3 is a block diagram showing an electronic construction of the control device 1. The control device 1 comprises a center processing unit 30, an oscillator 31 for generating clock pulses of suitable repetition frequency, a random access memory 32, a read only memory 33, a latch 34, and four input/output ports 35 to 38. The port 35 is connected to a printer 39 through a printer driver 40 and the port 36 is connected via a buffer 41 to a connector 42 to which the cable 2 is connected. The cable 2 is further connected to the vending signal generators of the machine. In general, the vending machine produces two kinds of signals, one indicating that coins have been put in and the machine is ready for vending and the other indicating a brand of product which has been selected by a user.Generally the vending operation of the machine is electrically in sequence and when enough coins amounting to the cost of the product are inserted, a vend allow signal is generated from a coin-mechanism, and when a selection signal is supplied from a selection unit, a vend motor and vend solenoid are driven by an activation signal to vend one or more products selected by the user. The vend signal to be received and stored by the control device may be the vend allow signal generated from the coin-mechanism and/or the activating signal. In this embodiment the activating signal is received as the vend signal. In this case the vend signal can identify the brand of product which has been vended.
The port 37 is connected to the connector 27 to which the program setter 3 or recorder 4 can be selectively coupled. The port 38 is connected to the print button 23, clear button 24, test button 25, stop button 26, test lamp 28 and status lamp 29. The control device 1 further comprises a stabilized D.C. supply source 43 for generating +8V voltage for the printer 39 and +5V voltage for electronic circuits. There is also provided a backup battery 44 for producing +3V voltage for protecting the data memory against interruption of the A.C. power supply. The ROM 33 is provided for storing the program signals and may have a capacity of, for example 2 k bites and the RAM 32 is used to store the vend data signals and has a capacity of, for instance, 256 bites.
Since the data signals are stored in the RAM and
C-MOS, the stored data can be retained therein for a quite long time such as several hundred days even if the A.C. power is not applied. Since the
CPU 30, RAM 32 and ROM 33 are sensitive to noise, they are electrically protected by a sealed case.
Before explaining the operation of the control device 1, functions of the four buttons 23 to 26 will be first explained.
(1) Print Button 23
With one push on the print button 23, one complete print-out of the data and information signals is effected, and the same signals are repeatedly printed-out until the clear button 24 is pushed.
(2) Test Button 25
When it is required to carry out a test vending, the test button 25 is depressed. The test lamp 28 will then light on which means that the control device 1 is ready for test vending. After one test vending is completed, the test vending mode will be automatically cleared and the test lamp 28 will turn off.
(3) Clear Button 24
When the clear button 24 is pushed, the data and information signal is once printed-out and the data signals will be cleared, but the information signals such as unit prices, registered machine number, etc. set by the program setter 3 are not cleared.
(4) Stop Button 26
During the printing when the stop button 26 is actuated, the printing operation is instantaneously stopped. Further the test vending can also be stopped by depressing the stop button 26. As will be explained later it is necessary to press the stop button 26 before setting the information signals into the control device-from the program setter 3.
(5) When the clear button 24 is pushed after actuating the test button 25, location commission data is printed out.
(6) By pushing the print button 23 after depressing the test button 25, a monthly summary of sales is printed-out.
It should be noted that by manipulating the buttons in the manner mentioned above with the recorder 4 being connected to the control device 1, the above data and information signals are also supplied to the recorder 4.
The control device 1 stores the vend data signals and the information signals in the RAM 32 and ROM 33. These signals may be explained as follows.
(1) Machine Number 8 digits
The registered machine number for identifying respective vending machines can be set in the control device 1 exclusively by the program setter 3.
(2) Unit Price of Products 3 digits
The sales data and unit price for respective products are stored in a column-wise manner exclusively by the program setter 3. The maximum number of columns available is 16. In each column corresponding to respective kinds of products the unit price of the related kind of product is stored exclusively by the program setter 3.
(3) Column Number (Product Code Number) 3 digits
In order to relate each column to respective kinds of products, the columns is expressed with a column number or a product code number by the program setter 3. The column number may be different from the column number.
(4) Number of Sales per Column 4 digits
The vend signal of particular product is counted and the count value is stored in the related column.
(5) Grand Total Number of Sales 6 digits
The number of sales of the machine is accumulated and is stored in a related column as a grand total number of sales by means of the program setter 3. The clear button 24 does not work on the thus pre-set counts and thus, the data of vends can be continuously stored and monitored for a long term. In order to avoid a possible error, an initial preset value is not zero, but is another value such as 1000.
(6) Number of Tests 4 digits
The total number of tests is stored for respective columns and can be cleared by actuating the clear button 24. The number of tests is added to the total number of vends, but not to the other data such as the number of sales per column, the amount of sales by cash, etc.
(7) Total Number of Sales 4 digits
This number is the total sales of all kinds of products, and may be cleared by the clear button 24.
(8) Total Sales Account 6 digits
The total sales account of all kinds of products is expressed by 6 digits and can be cleared by depressing the clear button 24.
(9) Location Commission 9 digits
In each column a unit location commission rate per unit product is stored by 3 digits and an calculated amount of location commission fee for all columns is stored by 6 digits. The commission rates can be cleared and changed exclusively by the program setter 3.
(10) Monthly Summarization Data
The control device 1 of the present embodiment can store and prints-out the following data as monthly summarization data.
a) Column-wise amount of sales 6 digits
A monthly number of sales for all columns or products are totalled, and can be cleared exclusively by the program setter 3.
b) Number of Tests 4 digits
The number of tests for all columns are accumulated for unit month, and can be cleared exclusively by the program setter 3.
c) Monthly Total Numbers of Sales 6 digits
The monthly total numbers of sales for all columns are accumulated as a monthly total number of sales which can be cleared exclusively by the program setter 3.
d) Monthly Total Account of Sales 6 digits
A monthly account of all products per month is accumulated as a monthly total account of sales which can be cleared exclusively by the program setter 3.
Since the printer 39 has a limited number of letters, it is necessary to use the letters alone as well as combinations which denote the following meanings.
(1) "C"
When the printing operation is effected by pushing the clear button 24, "C" mark is printed at the end.
(2)"T" "T" will be printed in front of the total number of sales.
(3) 'TC" "TC" will be put on in front of the location commission data.
(4) "tut" "TT" will be marked in front of the monthly number of sales.
(5) / 7
When the machine vends while printing out the data, "X; mark will be printed to indicate that the data just printed out should be invalid.
Fig. 4 shows some examples of data printedout on the tape 5 by the printer 39. A first example shown in Fig. 4A may be obtained in usual round. As described in the drawing a left hand figure of eight digits represents a machine number and a next figure consisting of T and six digits indicates a grand total number of sales. In this example the machine can vend six different kinds of products and six columns 1 to 6 are allotted to respective kinds of products. For instance, the third kind of product has a unit price of 100 and the number of vended products of this kind is eight. "-3" on the tape 5 indicates that the number of test vendings is three. "T63" represents the total number of sales is sixty three and "6200" indicates that the total sales account is 6200. The right hand side mark "C" is the reset or clear mark.
Fig. 4B shows another example of the printed tape. In this case the product codes are used for denoting the kinds of products instead of the column numbers.
Fig. 4C illustrates still another example of the printed tape when the test button 25 and the clear button 24 are pushed in this order. On the tape commission rates are printed together with product codes and the number of sales, and "TC=45876" indicates that the total location commission fee is 45876.
Fig. 4D shows still another example of the printed tape in which the monthly data has been put on by pushing the test button 25 and the print button 23 in this order. "T148519" represents the monthly total number of sales of the related machine. "1 01=60 x 1375" indicates that 1375 products having the product code 101 and a unit price of 60 have been vended during a related month. "to6441 . =458760" represents that the monthly total number of sales is 6,441 and the monthly total account of sales is 458,760.
Fig. 5 is a block diagram showing an embodiment of the recorder 4 to be connected to the control device 1. The recorder 4 comprises a connector 51 for connecting the recorder to the control device 1 by means of the connector 27 thereof shown in Fig. 3. The connector 51 is coupled via an input/output port 52 to a switching circuit 53 which is controlled by a control switch unit 54. The data signal and information signal transmitted from the control device 1 are further supplied through a control circuit 55 to a memory unit 56. The control circuit controls also a display circuit 57.The data and information signals such as the machine number, the column numbers, the product codes, the number of columns, the total number of sales, the unit prices, the commission rates, the total number of sales per column, the grand total number of sales, the totat account of sales, the number of tests, the monthly number of sales per column, the monthly grand total number of sales, the monthly total number of sales, the amount of location commission, etc. are transferred to the recorder 4 and can be stored in the memory unit 56. By suitably operating the control switch unit 54 of the recorder 4 as well as the various buttons 23 to 26 of the control device
1. The stored data and information signals can be further transferred from the recorder 4 to the data terminal 7 by connecting the recorder 4 via the connector 58 to the data terminal 7. According to the invention the important information signals such as the machine number, the column numbers, the number of columns, the product codes, the unit prices of respective kinds of products, the location commission rates, the grand total number of sales, etc. could never be changed by the recorder 4. These signals can be exclusively set by the program setter 3.
Fig. 6 is a block diagram showing an embodiment of the program setter 3 according to the invention. The construction of program setter is essentially similar to that of the recorder 4. The program setter 3 comprises a connector 61 to be connected to the connector 27 of the control device 1, an input/output port 62, a control circuit 63 a control switch unit 64 for controlling the operation of the control circuit 63 and a setting switch unit 65. By suitably operating a plurality of switches in the setting switch unit 65 after the program setter 3 being connected to the control device 1, the necessary information signals such as the machine number, column numbers, product codes, unit prices of respective kinds of products, total number of sales, commission rates, etc. can be set in the control device 1.
According to the invention such a setting operation can be carried out exclusively by the program setter 3, and thus the management of vending machines can be made extremely reliable and accurate. In the embodiment shown in Fig. 6 the information signals are produced by manipulating the setting switch unit 65, but in a modified embodiment the setting switch unit 65 may be replaced by a RAM in which has stored the necessary information signals. Then manipulation of the program setter 3 can be made much easier and more reliable.
The present invention is not limited to the embodiments explained above, but many modifications can be conceived within the scope of the invention. For instance, the control devices installed in the vending machines may be electrically connected to one or more terminal devices so as to transmit directly the data and information signals between the control devices and terminal devices. Further the data stored in the control devices is not restricted to those explained above but other data and information signals may be calculated and stored. Moreover other information signals such as date signal may be also printed-out or transmitted. Further the above mentioned system is used for controlling the operation of automatic vending machines, but it is clear that the system according to the invention can be equally applied to control and manage any type coin-operated machines such as coin game machines, coin-operated washing machines etc.
