Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for locking / unlocking a main door of a vending machine body, and more particularly to a locking device for an automatic vending machine developed for crime prevention.

[0002]

2. Description of the Related Art Locking in current vending machines is generally a so-called handle lock type, which is composed of a handle attached to a main door and a lock incorporated in the handle. With the handle lock type, the main door can be opened easily if the handle or lock is destroyed,
As a crime prevention measure, a double locking system has been added by adding a lock mechanism called hard lock or bull lock. Figure 10
As shown in, hard rock 101 and bull rock 1

The chain and the lock plate that are hung on 4 are locked by a lock, and these are attached to the outer surface of the vending machine (in the figure, both the hard lock 101 and the bull lock 102 are shown in the same drawing). ing).

[0003]

In any of the conventional locking devices as described above, even if any of them is exposed to the outside and is locked by a lock, it has the effect of visually appealing to a criminal. Destroying the heavy lock was a matter of time and time, and it was not a sufficient crime prevention measure. Moreover, on the operator side, when the main door is opened, it is necessary to perform the key release operation twice (the lock operation is also required once), and there is a problem that the handling becomes complicated.

However, if the electronic lock type is used instead of the mechanical handle lock type, the above problem is solved.
However, in such a case, a situation occurs in which the main door cannot be opened at a storage location where electricity cannot be energized or at the beginning of installation. In addition, crime prevention measures are required only for vending machines installed in places with low traffic, so
Therefore, it is uneconomical to manufacture a vending machine exclusively for electronic locks.

The present invention has been made to solve the above problems, and does not impair the handleability.
An object of the present invention is to provide a locking device for a vending machine that can improve the crime prevention performance.

[0006]

In order to achieve the above object, the present invention provides a mechanical first lock mechanism for locking / unlocking the closure of the main door of the vending machine body from the outside, and a main mechanism for the vending machine body. It is characterized in that it is provided with an electric second lock mechanism for locking / unlocking the closing of the door inside, and a starting means for activating the second lock mechanism.

In this case, the activation means is preferably controlled by a timer.

In these cases, the first locking mechanism is
The second locking mechanism has a moving member that moves for locking / unlocking, and the second locking mechanism engages / disengages with the moving member between a position that prevents the moving member from moving and a position that allows the moving member to move. It is preferable to have

Further, in these cases, it is preferable that the activation means is unlocked by a selective operation of a plurality of customer operation sections of the main door cryptographically combined.

[0010]

In the locking device for the vending machine according to the first aspect, the second locking mechanism for locking / unlocking the main door with respect to the vending machine main body is provided inside so that the first door can be operated from the outside.
Even if the lock mechanism of 1 is broken, the second lock mechanism is not broken, and the locked state of the main door can be maintained. Further, if the second lock mechanism is unlocked by the activation means, the first lock mechanism enables the second lock mechanism to be activated regardless of whether power is supplied or not, as in a normal vending machine.
The main door can be locked / unlocked on the vending machine body.

In the lock device for a vending machine according to a second aspect of the present invention, since the starting means is controlled by the timer, for example, the lock state of the second lock mechanism can be set only in the middle of the night when there is less traffic. In addition to being able to sufficiently achieve the purpose of crime prevention, it can be handled in the same way as a normal vending machine when loading products.

According to another aspect of the present invention, in the locking device of the vending machine, the movement of the moving member of the first locking mechanism for locking and unlocking is blocked or allowed by the movement blocking member of the second locking mechanism. By using a part of the first lock mechanism,
You can unlock. As a result, the number of parts of the second lock mechanism can be reduced and the structure of the second lock mechanism itself can be simplified without impairing crime prevention measures.

According to another aspect of the present invention, in the lock device for a vending machine, the activation means is unlocked by the selective operation of the plurality of customer operation sections of the main door cryptographically combined with each other, whereby a special remote controller is provided. The second lock mechanism can be unlocked by a selective operation of the customer service operation unit, for example, a selection button without using the above.
This is especially useful for unlocking the second locking mechanism that is locked by the timer setting (in an emergency).

The engagement of the locking protrusion 41a is allowed (see FIG. 9). The engagement of the locking protrusion 41a prevents the first lock plate 24 and the second lock plate 25 from moving in the unlocking direction,
The locked state of the main door 3 is maintained.

Further, the tail end of the locking plate 41 is formed in a mountain shape, and a valley-shaped groove is formed in the middle portion of the slide plate 43 so as to receive it. The tail end of the locking plate 41 and the trough-shaped groove of the slide plate 43 form a linear cam, and the sliding plate 43 moves up and down to move the locking plate 41 forward and backward. The locking protrusion 41a is engaged with and disengaged from the second lock openings 24b and 25b of the first and second lock plates 24 and 25. A coil spring 45 is attached to the locking plate 41, and the locking plate 41 is constantly urged by the coil spring 45 in the detaching direction.

Both solenoids 44a and 44b are controlled by the controller 11 connected thereto, and when the second lock mechanism 10 is locked, the controller 11 momentarily energizes only the solenoid 44b on the lower side to make the slide plate 43
Is moved downward (see FIG. 9) and when it is in an unlocked state, only the solenoid 44a on the upper side is instantaneously energized to move the slide plate 43 upward (see FIG. 6). In this case, the lower solenoid 44b that performs the lock operation can be replaced with a spring, but since it causes a problem that the lock is released at the time of a power failure, the solenoid is not always required to be energized. Therefore, it is possible to adopt another structure in which it is not necessary to constantly energize the solenoid.

The controller 11 has a timer 12
Is incorporated (both the controller and the timer use the microcomputer installed in the vending machine), and the timer 12 locks the second lock mechanism 10 only during the high crime period. . Furthermore, in order to ensure the locked state and the unlocked state by using this timer 12, when the locked state and the unlocked state are set, the corresponding solenoids 44a and 44b are continuously operated several times. Energized, and then
After a certain period of time, electricity is supplied periodically (for example, every hour). In this way, by locking the second lock mechanism 10 only during a high crime time period, for example, at midnight,
During the daytime, when performing a collection operation or a loading operation, the vending machine 1 can be handled by operating only the first lock mechanism 9.

On the other hand, in order to make it possible to release the locked state of the second lock mechanism 10 in the case of an emergency, in this embodiment, a large number of selection buttons 4 are selectively pushed.
The locked state of the second lock mechanism 10 can be forcibly released. It is preferable that the push button procedure is configured by a cryptographic combination. From the standpoint of fail-safety, it is also necessary to be able to release the locked state of the second lock mechanism 10 at the time of power failure. For example, a connector capable of energizing the upper solenoid 44 a is provided on the outer surface of the vending machine 1, or the upper solenoid 44 a
A battery power source capable of energizing a is built in, and the energizing switch is provided on the outer surface of the vending machine 1 so that the connector or the energizing switch can be operated by key operation.

As described above, according to the locking device of the present embodiment, the first lock mechanism 9 of the handle lock type and the second electric lock mechanism 10 having no operating portion on the outside are provided. Since the lock mechanism 10 is controlled by the timer 12, when collecting or loading normally performed,
It is possible to exert more reliable crime prevention performance without requiring a troublesome operation or an operation different from usual.

The second lock mechanism 10 is also provided with a controller 11 and a timer 12 that are normally included in the vending machine 1.
Can be used, and a part of the first lock mechanism 9 can also be used, so that it can be configured easily and at low cost.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in various modes. For example, in the case where the lock plate has a one-piece structure, the locking plate of the second lock mechanism is arranged so as to penetrate through the lock plate and the angle member fixed to the main door at the same time. The locking plate of the second lock mechanism is arranged so as to simultaneously penetrate the fixing plate fixed to the vending machine body. Further, the lock / unlock of the second lock mechanism may be controlled by the above-described selective operation of the selection button, the remote controller, the magnetic card, or the like.

[0030]

As described in detail above, the locking device of the vending machine of the present invention uses the mechanical first lock mechanism and the electric second lock mechanism effective for crime prevention in combination. In addition, the second lock mechanism can be operated in addition to the first lock mechanism only when necessary, so that the crime prevention performance can be significantly improved without impairing the handleability of the lock mechanism accompanying opening and closing of the main door. It has the effect of being able to.
