When the coin storage box is removed, the shutter is automatically closed and the lock mechanism locks the closed state. The collector delivers the coin storage box with the shutter closed to the manager, and the coin cannot be collected until the manager unlocks the manager lock and opens the coin storage box, and the lock mechanism locks. It is not possible to operate the set pin to release.

[0005]

[Problems to be Solved by the Invention] Since this coin storage box is an important item for handling money, after that, a mechanism to prevent erroneous operation of the collector and a lock for mounting confirmation to prevent fraudulent acts were added. As a result, the structure becomes more complicated, and the manufacturing cost becomes higher, the handling becomes complicated, and the durability is increased. The present invention is intended to solve such a problem, and has a structure that is simple and durable without impairing the conventional functions, has a low manufacturing cost, and has an advantage of being easy to operate, and is a lock for a practical coin storage box. It provides a mechanism.

[0006]

In order to achieve the above object, a lock mechanism of a coin storage box of the present invention is provided on a rear wall fixed to the back surface of a door of a vending machine and on the opposite side of the rear wall. A storage box mounting member having a front wall and a key that is vertically installed on the rear wall, and a guide that is pivotally attached at one end to the back side of the front wall and is urged to rotate in the direction of contacting the back surface of the front wall. A coin storage box provided with a lever, detachably attached to the storage box attachment member, and having an upper main body with a coin receiving opening provided on the upper surface, and a lower main body connected to the upper main body by a hinge, A shutter having a one-way clutch movably provided to open and close the coin receiving opening, and a projection having one end pivotally attached to the coin storage box and the other end abutting against the guide lever and engaging with the shutter Shutter lever and the shutter release A shutter spring for urging the shutter in the shutter closing direction, a shutter stopper for urging the shutter in the direction to engage the one-way clutch, and preventing the shutter from moving in the opening direction when engaged, and the upper body. A management lock that engages with the lower main body and a rotating member that is operated by a collector are provided, and when the coin storing box is attached to the storing box attaching member, the key is operated by the rotating member. The mounting confirmation lock to be inserted and unlocked is connected, and the start cam fixed to the mounting confirmation lock and having a play in the rotation direction with respect to the rotation member is rotated by the rotation member in the shutter opening direction. A pushing cam for pushing the shutter stopper in the disengagement direction by movement is provided.

The lock mechanism of the coin storage box is provided so as to be retractable from the coin storage box, is urged in a protruding direction by a stopper spring, and engages with the storage box mounting member when the coin storage box is mounted. A stopper may be provided, and the set cam fixed to the rotating member may be provided with a pushing protrusion that pushes the stopper in the retracted direction when the set cam rotates.

[0008]

In the lock mechanism of the coin storage box configured as described above, the shutter stopper engages with the one-way clutch of the closed shutter in a state before being mounted on the vending machine,
The shutter is locked in the closed state. When this coin storage box is inserted into the storage box mounting member, the projection of the shutter lever contacts the guide lever of the storage box mounting member. Since the shutter is locked in the closed state, the shutter lever that engages with the shutter cannot rotate, the projection of the shutter lever pushes the guide lever, and the guide lever moves away from the front wall against the biasing force. Rotate in the direction.

When the coin storage box is completely inserted, the stopper, which is biased in the direction of projecting from the coin storage box, projects and engages with the storage box mounting member, so that the coin storage box cannot be removed. On the other hand, the key of the storage box mounting member is inserted into the lock for confirming the mounting, and the rotating member becomes rotatable. At this time,
The shutter is still closed, and when the collector operates the rotating member in the shutter opening direction, the rotating member rotates in the direction without play with respect to the start cam and directly drives the start cam to start. The cam pushes the shutter stopper, the engagement between the shutter stopper and the one-way clutch of the shutter is released, and the shutter becomes movable.

When the shutter becomes movable, the shutter lever that engages with the shutter becomes rotatable, so that the guide lever that has been pushed in the direction opposite to the urging force pushes the shutter lever back and engages with the shutter lever. Moves in the opening direction and opens the coin receiving opening. Thus, when a coin is inserted into the vending machine, the coin drops into the coin storage box via the coin receiving opening.

The coin storage box with the accumulated coins is removed by a collector who goes around each vending machine, and a new empty coin storage box is attached. To remove the coin storage box, first, the rotating member is rotated in the shutter closing direction, the set cam rotates together with the rotating member, and the stopper pushed by the set cam causes the coin storage box to move. The coin storage box is retracted and the engagement with the storage box mounting member is released, so that the coin storage box can be removed.

On the other hand, since the rotating member rotates in a direction with play with respect to the start cam, the start cam does not rotate. Therefore, the shutter stopper remains engaged with the one-way clutch of the shutter, and the shutter is immovably restrained in the opening direction and movable only in the closing direction. The shutter is closed as the coin storage box is withdrawn, and is locked in the fully closed state when the withdrawal is completed.

After removing the coin storage box containing the coins, a new empty coin storage box is attached to the storage box attachment member. The coin storage box containing coins is delivered to the manager, and when the manager unlocks the manager lock, opens the coin storage box to collect the coins, and then locks the management lock, It can be attached to the vending machine again.

The stopper 58 pushed by the bending portion 60 of the pushing protrusion 43 of 42 is retracted into the coin storage box C, the engagement with the storage box mounting member B is released, and the coin storage box C can be removed.

On the other hand, since there is a play between the engaging projection 48 of the start cam 47 and the fan-shaped portion 40b of the rotating member 10,
The start cam 47 does not rotate (see FIG. 4). Therefore,
The shutter stopper 63 remains engaged with the one-way clutch 30 of the shutter 15, and the shutter 15 is prevented from moving in the opening direction and can move only in the closing direction.

As the coin storage box C is pulled out, the shutter 15 gradually closes the coin receiving opening 6, and the shutter 15
The shutter lever 24 rotates with the movement of the
(See (B)). When the removal of the coin storage box C is almost completed,
Since the position of the protrusion 25 comes to the position where it is separated from the restraint wall 77 (see FIG. 6C), the coin storage box C can be pulled out as it is (see FIG. 6D). When the extraction is completed, the shutter 15 is locked in the fully closed state.

After the coin storage box C containing coins is removed, a new empty coin storage box C is attached to the storage box attachment member B. Coin storage box C containing coins
Is delivered to the caretaker, and the caretaker uses the caretaker lock 11
Is unlocked, the coin storage box C is opened, and the accumulated coins are collected, and then the management lock 11 is locked, so that the vending machine B can be mounted again.
