Description

[Detailed description of the invention] The present invention relates to a locking device for a vending machine, in particular, the main body is partitioned into an arbitrary number of product storage chambers, and a lock is provided corresponding to the product storage chamber. This invention relates to a locking device for a vending machine in a vending machine, which has a storage space on the front side of the main body that can be opened only with a predetermined duplicate key.

Conventionally, a vending machine with such a configuration has a structure that allows the purchaser to re-storage the product in the storage chamber himself after the product is sold in the storage chamber and is received by the purchaser. When the door was closed, it was locked again and sales could be made again.

For this reason, in vending machines that handle packaged beverage products, there is a problem that the next customer will buy an empty container with no contents, and there is also a risk that mischief makers will appear who put loose foreign objects into the empty container. There was also the possibility that customers would be concerned about the product and that an accident could occur.

In view of the above points, the present invention is such that once the door of the sales outlet corresponding to the storage room that has been sold is closed, the door is locked and the products corresponding to that storage room cannot be sold.

An embodiment of the present invention will be described below in detail with reference to the drawings.

1st. FIG. 2 shows the main body and locking device according to an embodiment of the present invention, and FIGS. 3 to 7 show the operation of the present invention.

First, in FIG. 1, a decorative door 2 and a storage door 3 are provided on the front of a main body 1 equipped with a cooling mechanism (not shown).
Inside, a storage chamber 4 and a space 5 are formed which are divided into a required number of sections to store articles.

Further, the storage door 3 is provided with lockable sales openings 6 corresponding to the number of storage chambers 4, and a coin sorting device 7 for processing input coins and a locking device 8 are provided at positions corresponding to the spaces 5. It is a provision.

Further, on one side of the sales nozzle 6, locking devices A, B, and C shown in FIGS. 2 and 3 for locking the door, and a selection button 9 related to the coin sorting device T are arranged in series. be.

Each sales port 6 is kept locked by locking devices A and B before sale.

Further, the storage chambers 4 provided in the main body 1 are partitioned with linear members so that cool air can freely circulate within each chamber.

The sales face 6 has an L-shaped key member 10 constituting the locking devices B and C fixed on its inner surface, and is pivotally attached to the housing □ 3 so as to be rotatable.

Reference numeral 11 denotes a plate-shaped guide member, which is provided inside the storage door 3.

This guide member 11 has two rectangular openings 12 at the top and bottom.
, 12' are open, and the lower end is bent at a right angle to hook the spring 13.

This bent lower end 11' is fixed to a frame 14 inside the storage door 3.

Reference numeral 15 denotes a lock operation plate having an L-shaped cross section;
The guide member 11 is slidably supported through the openings 12 and 12' by support shafts 1617 implanted above and below the guide member 11, and its lower end is hooked by a spring 13 and is constantly biased downward.

Since this lock operation plate 15 has an L-shaped cross section, one piece thereof serves as a sliding surface along the guide portion #11 as described above, and the other side serves as a sliding surface for locking the key member 10. A concave cutout 19 is provided with a protrusion 18 to be locked;
A movable protrusion 20 is rotatably provided vertically so as to protrude downward from the upper end of the cutout 19, and is operated by the operation of the selection button 9, and is connected to a follower 23 of a solenoid 21 constituting the locking device A. A lock hole 22 for engagement is opened.

Since the follower 23 of the solenoid 21 has a spring 23' wound around it, it is always fitted into the lock hole 22 due to the elasticity of the spring 23' when no sales signal is sent.

A concave portion 24 is provided in the key member 10 and the movable protrusion 20 in the housing.
25 is provided, and when engaged constitutes a locking device C.

The length t of each of the openings 12 and 12' is set to be slightly longer than the length of the engagement t1 between the key 10 and the protrusion 18 plus the distance.

The distance is the distance that the lock operation plate 15 descends when the sales face 6 is opened after the locking devices A and B are unlocked.

This is so that when the movable protrusion piece 20 is fitted into the recessed part 24 after the key member 10 rotates the movable protrusion piece 20 when the sales face 6 closes, the movable protrusion piece 20 does not return to its original rotation (spring 1
3 urges the lock operation plate 15' downward), the movable protrusion 20 and the key member 10 engage with each other.

In the above configuration, when the coin sorting device 7 receives a proper coin while the storage □ 3 and all the sales counters 6 are closed and locked, a sellable signal is generated.

In this state, the locking devices A and B are in a locked state as shown in FIGS. 2 and 3.

When an arbitrary selection button 9 is pressed, the corresponding solenoid 21 is operated, and its follower 23 is pulled and removed from the lock hole 22 as shown in FIG. 4, and the locking device A is unlocked. Due to the spring 13 and its own weight, the key member 1 descends a little longer than the engagement type t1 between the protruding piece 18 and the key member 10.
The movable protrusion 20 is blocked on the upper surface of 0 and stops descending,
Locking device B is also unlocked.

That is, in this state, the sales face 6 can open the door.

Furthermore, when the sales door 6 for withdrawing the products stored in the storage chamber 4 is opened, the key member 10 and the movable protrusion 20 come out of contact and the lock operation plate 15 is opened as shown in FIG. It descends further along the guide member 11 by a further distance.

After this lowering, when the customer releases the sales face 6 from his hand, it is rotated back as shown in FIG. 6 by the biasing force of a spring (not shown), and the movable protrusion 20 is rotated in the direction of the arrow by the key member 10. Eventually, one side of the movable protruding piece 20 bites into the recessed part 24 provided in the key member 10, forming a locking device C.

In this locked state, it is impossible for a person selling the product to open the door 6 no matter what.

It is possible to store the product in the storage room 4 in 1, where you close the sales face 6, but after closing the product, it is impossible to automatically sell the product even if you insert the specified amount of money again. be.

□In order to unlock the locking device C locked in this way, the lock operation plate 15 must be raised, and the locking device 80 must be raised.
This is possible only for the administrator who owns the duplicate key.

That is, after opening the storage door 6, the support shaft 16 is manually raised to the lock operation plate 15 to the original locking position, and the lock hole 22 is opened.
What is necessary is to fit the follower 23 therein.

When a new product is stored in the storage chamber 4 and the storage door 3 is closed, the state shown in FIG. 3 is restored.

As described above, the present invention is such that the sales face corresponding to the product once ordered by the customer cannot be opened again and sold automatically depending on the customer.

Therefore, once a customer has consumed something, another customer will not buy it.

Even if a foreign object is mixed into a product container or a prank is committed, the same product cannot be ordered again, so damage to future customers can be prevented.

Furthermore, the anxiety that customers have about the products in this type of vending machine can be alleviated.

Moreover, its structure is extremely simple, and its effects are outstanding.
