Abstract

PROBLEM TO BE SOLVED: To prevent illegal unlocking of lock mechanism used for an automatic vending machine or the like. SOLUTION: When a lock is rotated clockwise by key operation, a connector 14 provided at a case is exposed. When an identification number input machine 100 is connected to a connector 14 of the exposed connector 14 to input a predetermined identification number from the input machine 100, a CPU 120 compares this inputted identification number with an identification number previously registered in a memory 121. When both numbers coincide with each other, a transistor Q is turned on to apply current to a solenoid 35. An actuator is therefore put in action to unlock a door.

If the operation of the second switch 28 is canceled without the operation of the second switch 28 being canceled or the operation of the second switch 28 not being operated, it is determined that the door 4 has been pryed open without using a key, and the alarm generation unit 122 described later is used. Operate and generate an alarm.

As shown in FIG. 7, a solenoid 35 is fixed to the upper part of the inner surface of the door 4 via a bracket 34. The solenoid 35 is provided with an actuator 36 as a second locking means. A compression spring 37 is elastically mounted between the flange portion 36a of 36 and the solenoid 35. Reference numerals 38 and 39 denote a pair of lock pieces fixed to the inner surface of the door 4, which face each other at an interval slightly larger than the thickness of the lock portion 10 of the above-described edge 9, and face the lock holes 38 a and 39a is drilled. These lock pieces 38 and 39 are positioned such that when the opening 3 of the housing 2 is closed by the door 4, the lock portion 10 is engaged in the gap between the lock pieces 38 and 39. At that time, both lock pieces 38,
The lock holes 38a, 39a of the lock portion 39 correspond to the lock holes 10a of the lock portion 10.
The actuator 36 is positioned so as to engage within 0a. Reference numeral 40 denotes a third switch fixed to the inner surface of the door 4 via a bracket 41,
When the actuator 36 is energized and the actuator 36 retracts in the direction of arrow A against the urging force of the compression spring 37, the actuator 36 is positioned to operate by the flange portion 36a.

Next, the opening / closing operation of the door having the above-structured housing will be described. As shown in FIG. 4, when the opening 3 of the housing 2 is closed by the door 4, the hook portions 17 b and 27 b of the left and right lock plates 17 and 27 are engaged with the pins 31 and 31 of the door 4. At the same time, as shown in FIG. 5, the actuator 36 of the solenoid 35 advances by the urging force of the compression spring 37, and the lock pieces 38, 39
And the lock holes 10a of the lock portion 10 of the rim 9 are engaged with the lock holes 38a, 39a. As described above, both sides of the opening 3 of the housing 2 are locked by the left and right lock plates 17 and 27, the upper part of the opening 3 is locked by the actuator 36, and the lower part of the opening 3 is substantially locked by the hinge 6. Thus, all four sides of the opening 3 are locked. For this reason, it becomes difficult to pry open the door 4 from any of the four sides of the opening 3, and the security of the housing 2 is maintained.

In this state, as shown in FIG. 6, when the lock 11 is rotated clockwise in the figure by a key (not shown), the shutter plate 12 also follows and rotates clockwise. The pressing of the contact portion 17c by the portion 12b is released, and the lock plate 17 rotates counterclockwise by its own weight around the pin 18A as a rotation center. Therefore, the engagement between the hook portion 17b of the lock plate 17 and the pin 31 is released. The rotation of the lock plate 17 causes the shaft 2
3 rotates counterclockwise via both levers 20A and 22A, so in FIG. 3 the lock plate 27 rotates clockwise about the pin 18B via levers 22B and 20B. . Therefore, the engagement between the hook portion 27b of the lock plate 27 and the pin 31 is released.

At this time, as shown in FIG. 6, the shutter plate 12 falls down, the connector 14 covered by the shutter portion 12a is exposed from the window 2a, and the first
Is operated by the shutter unit 12a.
By connecting the identification number input device 100 to the connector 14 and inputting the identification number, the solenoid 35 is energized, so that the actuator 36 retreats against the urging force of the compression spring 37 as shown in FIG.

Accordingly, the engagement of the actuator 36, which has been engaged with the lock holes 38a, 39a of the lock pieces 38, 39 and the lock hole 10a of the lock portion 10 of the rim 9, is released, and the locking by the actuator 36 is released. And the third switch 40 is provided by the flange portion 36a.
Works. As described above, the lock plates 17, 2
7 is also unlocked, so as shown in FIG.
The door 4 pivots counterclockwise in the figure about the pivot 7 of the hinge 6 as a pivot, and the opening 3 of the housing 2 is opened.

At this time, the operating switch 32 of the door 4 switches the operating state of the second switch 28 to the non-operating state, but the first switch 15 and the third switch 40
Has been switched to the operating state, it is determined that the door 4 has not been pryed open, and the alarm
2 does not work. As described above, since the locking of the actuator 36 is released based on the identification number, it is not necessary to increase the number of locking keys, so that key management is not complicated. Normally, the shutter portion 12 of the shutter plate 12
In order to unlock the lock by the actuator 36 by covering the connector 14 with a and exposing it from the window 2a by the key operation of the lock 11, it is necessary to unlock the lock 11 by a key operation. Therefore, it becomes difficult for a third party who does not have a key to input an identification number to the connector 14, and even if an attempt is made to open the door 4 without operating the key of the lock 11, the locking by the actuator 36 is unlocked. The security of the housing is maintained.

Next, the operation of closing the opened opening 3 of the housing 2 with the door 4 will be described. From the state shown in FIG.
Is rotated clockwise about the support shaft 7 of the hinge 6 and the opening 3 of the housing 2 is closed by the door 4 as shown in FIG. Therefore, the energization of the solenoid 35 is released. Therefore, as shown in FIG. 5, the actuator 36 moves forward by the urging force of the compression spring 37 and engages in the lock holes 38a, 39a of the lock pieces 38, 39 and the lock hole 10a of the lock portion 10 of the bezel 9. Therefore, locking by the actuator 36 is performed. Thus, door 4
When the opening 3 of the housing 2 is closed by this, locking by the actuator 36 is automatically performed, so that forgetting to lock can be prevented, and security is maintained.

In the state shown in FIG. 6, when the lock 11 is rotated counterclockwise in the figure by the key, the shutter plate 12 also rotates counterclockwise.
As a result, the first switch 15 which has been in the operating state due to a becomes inoperative, and the connector 14 is covered with the shutter portion 12a. At the same time, the pressing portion 1 of the shutter plate 12
2b presses the engaging portion 17c of the lock plate 17, so that the lock plate 17 rotates clockwise in FIG. 4 around the pin 18A, and as shown in FIG. Engage. When the lock plate 17 rotates clockwise, the shaft 25 moves the lever 20.
3A, the lock plate 27 rotates counterclockwise in FIG. 3 around the pin 18B via the levers 22B and 20B. The hook portion 27b of the lock plate 27 is
, The door 4 is locked by the lock plates 17 and 27.

FIG. 1 is a block diagram of a control unit for controlling a vending machine. The control unit includes a CPU 120 for controlling unlocking and locking of the door 4 of the housing 2, a memory 121 connected to the CPU 120, an alarm generation unit 122, and an identification number input from the identification number input device 100. Buffers 123 and 124 input through resistors R1 to R7 and transmitted to CPU 120, inverter 1NV and transistor Q driven by CPU 120 to energize / deenergize solenoid 35, and unlocking device connected to connector 14B in an emergency. The relay 130 is turned on by the power supply from the power supply 110 to energize the solenoid 35.

The CPU 120 has a first switch 1
5, Each contact output of the second switch 28 and the third switch 40 is input. The buffer 123 is connected to the column output lines COL1 to COL3 of the identification number input device 100 via resistors R1 to R3, respectively, and the buffer 124 is connected to the row output line ROW1 of the identification number input device 100.
4 are connected via resistors R4 to R7, respectively, and each of the buffers 123 and 124 is connected to the input identification number input device 100.
Is transmitted to the CPU 120. here,
The row output line ROW4 from the identification number input device 100 is commonly connected to the ground output line EXGND of the unlocking device 110, but the identification number input device 100 is connected to the connector 14A.
When the unlocking device 110 is connected to the
4B, the identification number input device 100
The operation data via the row output line ROW4 is input to the buffer 124 as it is.

In addition, although not shown, the vending machine has a selection button for selecting a product, a selection mechanism for selecting input money, and a storage for storing the selected money in a safe. A mechanism and a product discharging mechanism for sending out the selected product to the product discharging unit are provided.
It is connected to PU120.

Next, the operation of the main part of the control unit configured as described above will be described. In the state shown in FIG. 4, when the lock 11 is rotated clockwise by the key, as shown in FIG.
When the shutter plate 12 falls down, the shutter portion 12a
Is exposed from the window 2a, and the first switch 15 is operated by the shutter unit 12a. When detecting the operation state of the first switch 15, the CPU 120 inputs, via the buffers 123 and 124, the identification number from the identification number input device 100 connected to the next exposed connector 14 and operated. And
When the input identification number matches its own identification number registered in advance in the memory 121, the transistor Q is turned on via the inverter 1NV.

When the transistor Q4 is turned on, a current flows from the + 24V terminal of the power supply (not shown) to the transistor Q4.
1 flows to the ground GND via the solenoid 35, and as a result, the solenoid 35
Is energized. When the solenoid 35 is energized, the actuator 36 shown in FIG.
Operates, and the door 4 rotates counterclockwise to open the opening 3 of the housing 2 as shown in FIG. Also, the second
Switches from the operating state to the inactive state. In this case, when detecting the operation state of the third switch 40, the CPU 120 determines that the door 4 has been normally opened. If the operation state of the third switch 40 is not detected, it is determined that the door 4 is kept closed, and the alarm generation unit 122 generates an alarm.

Next, when the opening 3 of the opened housing 2 shown in FIG. 8 is closed by the door 4 as shown in FIG.
Switch 28 changes from the non-operation state to the operation state. CP
When U120 detects the operating state of the second switch 28, it turns off the transistor Q and stops energizing the solenoid 35. As a result, as shown in FIG. 5, the actuator 36 moves forward, and locking by the actuator 36 is performed. Thereafter, in the state shown in FIG. 6, the lock 14 is rotated counterclockwise in the figure by the key, so that the connector 14 is covered by the shutter portion 12a and the door 4 is locked.
Then, at this time, the first switch 15 that has been in the operation state is in the non-operation state. When detecting the inoperative state of the first switch 15, the CPU 120 recognizes that the locking of the door 4 has been completed.

FIG. 2 shows a CPU for controlling unlocking of a vending machine.
6 is a flowchart showing the operation of the H.120. The operation of the main part of the present invention will be described in detail according to this flowchart. When the lock 11 is rotated by the key, the shutter 12
The connector 14 covered by a is exposed from the window 2a, and the first switch 15 is operated by the shutter unit 12a to be turned on in step S1. First switch 15
CPU 120 starts the built-in timer (not shown) in step S2, and determines in step S3 whether or not an identification number has been input based on the input operation of identification number input device 100 connected to exposed connector 14. .

When the identification number is entered, the entered identification number is compared with its own identification number registered in the memory 121 in advance to determine whether the entered identification number is OK? It is determined in step S4 whether or not it is.
Then, when the entered identification number matches the registered identification number, the “identification number OK?” Of step S4 is changed to “Y”.
Is determined, the CPU 120 turns on the transistor Q in step S5 to energize the solenoid 35 as described above. As a result, the actuator 36 shown in FIG. 7 is retracted, the third switch 40 is operated and turned on, and the door 4 is rotated to open the opening 3 of the housing 2 as shown in FIG. At this time, the second switch 28 switches from the on state to the off state.

Here, the CPU 120 determines whether or not the third switch 40 is turned on in step S6. If the third switch 40 is turned on, the CPU 120 determines that the door 4 has been normally opened, and ends the processing. If the ON of the third switch 40 is not detected, it is determined that the door 4 is kept closed, and the alarm generator 122 is driven to generate an alarm (alarm) in step S7. Note that the input identification number does not match the identification number of the memory 121, and the process proceeds to step S4.
If the determination is "N", the process returns to step S3.

When the identification number is not input from the identification number input device 100 and the determination in step S3 is "N", the internal timer is determined to be timed up in step S8, and the internal timer is timed up. If not, step S3
Return to When the built-in timer times out without inputting the identification number, or when the built-in timer times out without inputting the identification number and the identification number does not match the identification number in the memory 121, the process proceeds to step S8. The determination is “Y”, and in this case, the alarm generation unit 122 is driven in step S9 to generate an alarm, and the processing ends.

As described above, even if the key is stolen and the lock 11 is unlocked by the stolen key, the door 4 is not unlocked unless the identification number matches, so that the door 4 is stored in the safe inside the housing. Money theft can be reliably prevented. Further, even if an unauthorized person who has stolen the key performs an unlocking operation using the key, an alarm is output because the unauthorized person cannot input the identification number, and as a result, the unlocking action of the unauthorized person is reported. be able to. In FIG. 1, the alarm generation unit 122 is connected to the CPU 120, and the CPU 120 directly drives the alarm generation unit 122 to generate an alarm. The information may be transmitted to the center and reported to the center.

By the way, in such a locking mechanism, when the CPU 120 of the control unit runs away or power is not supplied to the control unit, the door 4 is opened even if the identification number is input from the identification number input device 100. Can not. For this reason, the lock 11 is rotated by the key in the state shown in FIG. 4 to expose the connector 14 covered by the shutter portion 12a from the window 2a as shown in FIG. 6, and then to the connector 14B shown in FIG. An unlocking device 110 incorporating a battery having a voltage of +24 V is connected. That is, the ground output line EXGND of the battery of the unlocking device 110 is connected to the input line of the connector 14B commonly connected to the input line of the connector 14A to which the row output line ROW4 from the identification number input device 100 is connected, A power supply output line EX24V of the battery is connected to the other input line of the connector 14B.
(In this case, the ground output line EXGND of the battery of the unlocking device 110 may be directly connected to the input line to which the row output line ROW4 from the identification number input device 100 is connected.)

Then, a current flows from the battery of the unlocking device 110 through a path indicated by the reference numeral in FIG.
Is energized. In this case, the current from the unlocking device 110 is first supplied to the coil 131 of the relay 130 via the connector 14B.
Relay 130 which is normally in the open state indicated by the solid line.
Are brought into the closed state shown by the dotted line. Thus, the current from the battery of the unlocking device 110 is
The current flows to the ground GND via the contact 133 and the solenoid 35, and the solenoid 35 is energized. As described above, the actuator 36 shown in FIG. 7 is retracted by the energization of the solenoid 35, and as a result, as shown in FIG. 8, the door 4 rotates counterclockwise and the opening 3 of the housing 2 is opened. As described above, even when each circuit of the control unit that controls the locking mechanism of the vending machine is defective or when power is not supplied to each circuit, the unlocking device 110 is connected to the connector 14B and the unlocking device 110 is connected. , The door 4 is unlocked and rotated to open the opening 3 of the housing 2 by directly applying an electric current to the solenoid 35. In this embodiment, an example of a vending machine has been described. However, the present invention is not limited to a vending machine, and the same effects can be obtained even when applied to other devices.

[0033]

As described above, according to the present invention, the locking means is constituted by the solenoid and the lock attached to the housing, and the lock is turned by operating a key and attached to the connector provided on the housing. The unlock current is output to the solenoid based on the input of the predetermined identification number from the identification number input device to unlock the door, and if the identification number is not input within a certain time after the key is operated, an alarm is issued. Because it is output, even if the key is stolen, it is not easily unlocked,
Therefore, it is possible to reliably prevent the money stored in the vending machine from being stolen. In addition, even if the key is stolen and the unlocking operation is performed using the key, an alarm is output because the unauthorized operator cannot enter the identification number,
As a result, the unlocking operation by the unauthorized operator can be notified. In addition, an emergency unlocking machine with a power supply is provided, and the emergency unlocking machine is connected to the connector, the unlocking current is output from the power supply to the solenoid, and the door is unlocked. The lock can be unlocked in the event of a power failure or power failure of the device. In addition, the connector is exposed when the lock is rotated by operating the key, so that even if an unauthorized operator performs an unlocking operation using a stolen key, only the connector is exposed, and the unauthorized operator does not It is not clear how the connector will be used, so that it is possible to keep the unauthorized operator from having to enter an identification number from an identification number input device. Further, since a part of the signal line from the identification number input device is used to output the unlocking current from the emergency unlocking device to the solenoid via this signal line, the cost of the device can be reduced. In addition, when it is detected that the opening of the opened housing is closed by the door, the energization to the solenoid is stopped and the door is locked. Since it is not unlocked, unauthorized unlocking of a locking mechanism used in a vending machine or the like can be prevented.
