When a transport mechanism is mounted on a vending machine, or when a transport mechanism of a different type is exchanged (for example, direct stacking). For example, when replacing the transport mechanism with a chain elevator transport mechanism), the assembly parts and control methods differ for each transport mechanism, so the attendant checks the type of transport mechanism that has been installed, and checks the type. It is necessary to input the data corresponding to the data from the keyboard for changing the setting and to make the setting, so that the control unit of the vending machine recognizes which transport mechanism is installed.

[0003]

Therefore, in a conventional vending machine, when assembling a transport mechanism or replacing the transport mechanism with a different type of transport mechanism, an attendant checks the transport mechanism and checks the transport mechanism. A lot of trouble and time has been spent on the data input operation corresponding to. In addition, there is a risk that a staff member forgets to change the data, inputs the data incorrectly, or initializes the data. In these cases, the control of the transport mechanism is in a poor state. For this reason, there is a problem that the sales operation as a vending machine is also defective, and the reliability is reduced.

The present invention solves the above-mentioned problem, and is suitable as a vending machine even when a transfer mechanism is assembled or replaced with a different type of transfer mechanism without a staff member having to input a change of a setting keyboard.

Is provided.

[0006] According to this configuration, the type of the transport mechanism that has been mounted can be determined by the control unit and automatically recognized, so that even when the transport mechanism is mounted or replaced with a different type of transport mechanism. Even if the operator does not input the change of the setting keyboard, the type of the transport mechanism is recognized by the control unit, so that the vending machine functions well.

According to a second aspect of the present invention, there is provided a vending machine control device according to the first aspect, wherein an input-only terminal for discriminating the type of the transport mechanism is not provided. The control unit is provided with a common input terminal for inputting signals from the transport mechanism, and the difference in the combination of input signals from the transport mechanism to the control unit can be determined by the components provided in the transport mechanism and the unique transport function based on the operation This is configured so as to be caused electrically by the difference.

[0008] According to this configuration, the combination of input signals from the transport mechanism to the control unit is electrically generated due to the difference in the components provided in the transport mechanism and the unique transport function based on the operation thereof. Can automatically recognize the type of transport mechanism that has been assembled based on the input signal from the common input terminal, and it is not necessary to provide an input-only terminal for determining the type of transport mechanism.

On the other hand, the conductive brush 22 is separated from the third conductive portion 21c. The cam switch 38 is off. In this state, when the control unit 1 detects that there is a payout instruction, as shown in FIGS. 11 and 12, the voltage of the first common output terminal (COM1) becomes low (hereinafter abbreviated as L).

As described above, the first common output terminal (COM
When a predetermined time elapses after the output signal of 1) is set to L, the output signal of the first motor output terminal (MX1) is then switched to H, and the rotary motor 16 is moved in the forward direction (the product storage room (column) 11). Is an odd number), whereby the conductive brush 22 separates from the second conductive portion 21b,
The second cam switch 39 switches to the OFF state, whereby the input signals of the first and second input terminals (cam 1SW, cam 2SW) both become H (portion indicated by the period).

Further, when the rotary motor 16 is rotated in the forward direction, the conductive brush 22 is thereby moved to the third conductive portion 21.
c, the first cam switch 38 is switched to the ON state, whereby the first input terminal (cam 1S
Only the input signal of W) switches to L (portion indicated by the period).

When it is detected that the first cam switch 38 has been switched to the ON state, the rotation motor 16 is further rotated in the forward direction for a predetermined time, and then the first motor output terminal (MX1) is turned on. Is returned to L, the rotation motor 16 is stopped, and thereafter, the first common output terminal (COM1) is switched from L to H, and at the same time, the second common output terminal (COM1) is switched. COM2) is H
To L.

When a predetermined time has elapsed, the output signal of the second motor output terminal (MX2) is switched to H, and the rotary motor 16 is rotated in the reverse direction.
The conductive brush 22 separates from the third conductive portion 21c,
Is switched to the OFF state, and as a result, the first and second input terminals (cam 1SW, cam 2SW)

Further, when the rotary motor 16 is rotated in the reverse direction, the conductive brush 22 comes into contact with the second conductive portion 21b, and the second cam switch 39 is turned on.
As a result, only the input signal of the second input terminal (cam 2SW) switches to L (portion indicated by the period).

When it is detected that the second cam switch 39 has been switched to the ON state, the rotation motor 16 is further rotated in the reverse direction for a predetermined time, and then the second motor output terminal (MX2). Is returned to L, the rotary motor 16 is stopped in the initial standby state, and the second common output terminal (COM2) is switched from L to H.

When the product storage room (column) 11 is an even number, the rotation direction of the rotary motor 16 is controlled to be opposite, and the first and second input terminals (cam 1S) are controlled.
W, cam 2SW) is in the state shown in the lower half of FIG.

The transport mechanism A installed in the vending machine
Is the chain elevator transport mechanism 40,
The chain elevator type circuit 50 shown in FIG. 10 is attached. This chain elevator type circuit 50
Is obtained by adding two diodes D6 and D7 to the chain elevator type circuit conventionally used as described above, whereby the second common output terminal (COM2) changes from H to L. When the switching is performed as described above, as shown in FIG. 14, the input signals of the first and second input terminals (cam 1SW and cam 2SW) are both set to L.

The chain elevator type transfer mechanism 40
9, in the standby state, as shown in FIG. 9, the position detectors 48 disposed in the respective product storage rooms 41 are also in contact with the product receiving cradle 46 to be turned on. In this state,
For example, when an instruction to pay out only the product D in the odd-numbered product storage room 41 is notified to the control unit 1, the control unit 1 executes the processing shown in FIG.
3. First, as shown in FIG. 14, after the output is switched so that only the output signal of the first common output terminal (COM1) becomes L, the first motor output terminal (MX1) after a lapse of a predetermined time. Is switched to H, and the drive motor 45 of the odd-numbered product storage chamber 41 starts to rotate in a predetermined direction (portion indicated by a period).

Thereafter, the product receiving table 46 separates from the position detecting section 48 of the product storage room 41, and the position detecting section 48
The state is switched to the FF state, whereby only the input signal of the first input terminal (cam 1SW) becomes H (portion indicated by the period).

When the drive motor 45 of the product storage chamber 41 is subsequently rotated, the position detector 48 causes the next product receiving table 46 to be detected.
Is brought into contact with the first input terminal (cam 1S
Since the input signal W) returns to L, the first

When the product storage room (column) 41 is an even-numbered product storage room, the drive motor 45 of the even-numbered product storage room 41 is controlled to be driven as shown in FIG. 1, second input terminal (cam 1SW, cam 2
SW) is in the state shown in the center of FIG. When the product B is stored over two product storage rooms 41, as shown in FIG. 16, both drive motors 45 of the odd-numbered and even-numbered product storage rooms 41 are simultaneously driven. And the first and second
The input signals of the input terminals (cam 1SW, cam 2SW) are as shown in the lower part of FIG.

As shown in FIG. 1B, when the power of the vending machine is turned on and the reset operation is performed, the control unit 1
Proceeding from step S1 to step S2, the discriminating unit 2 performs a discriminating operation for discriminating the type of the transport mechanism A that has been assembled. That is, in step S2, the output signal of the second common output terminal (COM2) is set to L, and in step S3, the first and second input terminals (cam 1SW, cam 2S
W) if at least one of the input signals is H,
Proceeding from step S3 to step S4, it is determined that the transport mechanism A is the direct stack type transport mechanism 10, and if both the input signals of the first and second input terminals (cam 1SW, cam 2SW) are L. From step S3 to step S5,
It is determined that the transport mechanism A is the chain elevator transport mechanism 40.

Thus, when the reset operation is performed,
The type of the transport mechanism A that has been mounted is determined by the determination unit 2 of the control unit 1 and is automatically recognized, and a control operation suitable for each of the transport mechanisms 10 and 40 that are mounted is performed. Works well.

As a result, much labor and time are not required for the operation of confirming the transport mechanism A and the operation of inputting the data corresponding to the transport mechanism A, which were conventionally performed by the attendant, thereby improving the work efficiency. . Also, as in the past, the attendant forgot to change the data, entered the data incorrectly, or initialized the data,
Since the control of the transport mechanism can be prevented from being in a poor state, the reliability as a vending machine is also improved. Further, since there is no need to provide an input-only terminal for determining the type of the transport mechanism, it is possible to reduce the manufacturing cost.

Further, in the above embodiment, the case where the selectable transport mechanism A is the direct stack transport mechanism 10 and the chain elevator transport mechanism 40 has been described. It is also possible to determine the transfer mechanism using the electromagnetic solenoid.

In other words, an electromagnetic solenoid type transfer mechanism such as a serpentine type transfer mechanism has a structure in which products are paid out by energizing the electromagnetic solenoid for a predetermined time. Unlike a motor, position control for transfer is not performed. 17
As shown in the figure, the first and second common output terminals (COM
1, COM2) and first and second motor output terminals (M
X1, MX2), respectively, only by connecting the electromagnetic solenoid 60 to the first and second input terminals (cam 1S).
W, cam 2SW) is not connected to any circuit. Therefore, the first and second input terminals (cam 1SW, cam 2S
All the input signals to W) are always H.

Usually, the direct stacking type transport mechanism 10 is installed in a standby state. Therefore, when the reset operation is performed, as shown in FIG. 18, the process proceeds from step S1 to step S2, where the control unit 1 sets the output signal of the second common output terminal (COM2) to L, and in step S6 The determination operation of the transport mechanism A is performed. That is, the first and second
If both of the input signals of the input terminals (cam 1SW and cam 2SW) are H, it is determined that the transport mechanism is an electromagnetic solenoid type transfer mechanism (step S7), and the first input terminal (cam 1S
If the input signal of W) is H and the input signal of the second input terminal (cam 2SW) is L, it is determined that the transport mechanism A is the direct stack type transport mechanism 10 (step S8), and the first and the first transport mechanisms are determined. If both of the input signals of the input terminals 2 (cam 1SW and cam 2SW) are L, it is determined that the transport mechanism A is the chain elevator transport mechanism 40 (step S9), and the respective transport mechanisms are determined. It is possible to perform a suitable control operation.

Further, first and second input terminals (cam 1S
When both the input signals of the W, cam 2SW) are H, the control for the direct-stacking-type transport mechanism 10 is temporarily performed on a trial basis, and at this time, the first and second input terminals ( Cam 1
If any of the input signals of the SW and the cam 2SW) becomes L, it is determined that the transport mechanism 10 is the direct stacking type transport mechanism 10, and the input signals of the first and second input terminals (cam 1SW and cam 2SW). If either of them does not become L, it may be determined to be the electromagnetic solenoid type transport mechanism.

In the above embodiment, the case where one type of transport mechanism is incorporated in one vending machine has been described. However, the present invention is not limited to this, and two or more types of transport mechanisms may be installed in one automatic vending machine. It is needless to say that the present invention can be applied to the case where it is incorporated in a vending machine, and in this case, it is convenient and useful because it saves time and labor.

[0042]

As described above, according to the present invention, the control unit is provided with the discriminating unit for discriminating the type of the already-installed transport mechanism based on the combination of the input signals of the input terminals. The control unit can automatically recognize the type of transport mechanism, and even if the transport mechanism is assembled or replaced with a different type of transport mechanism, the staff can change and input data from the setting keyboard. Even if not performed, the type of transport mechanism is recognized by the control unit and functions well as a vending machine, and it takes much time and effort to check the transport mechanism and input data corresponding to the transport mechanism that were conventionally performed by the attendant. Time is not required, and work efficiency is improved. In addition, as in the past, it is also possible to prevent the attendant from forgetting to change the data, inputting the data incorrectly, or initializing the data, resulting in poor control of the transport mechanism. As a result, reliability as a vending machine is improved.

The difference in the combination of the input signals from the transport mechanism to the control unit is due to the difference in the components provided in the transport mechanism and the specific functions based on the operation thereof. Since there is no need to provide an input-only terminal for determining the type of the transport mechanism,
Manufacturing costs can be reduced.
