Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a theft prevention device for stored products in a vending machine in which cylindrical products such as bottle products are stored in a horizontal position.

In vending machines that generally handle bottled products,
As shown in FIG. 1, a bottled product 3 is stored in a horizontal position in a product discharging mechanism 2 disposed inside the main case. In response to the sales command, the bottled products 3 fall sequentially from the lowest one onto the lower shutter 5, are sent forward, pass through the opening 7 of the inner door 6, and are placed between the inner door 6 and the outer door 8. The product falls into the provided bucket 9 and is taken out from the product outlet 10. The opening 7 has an inner flap 11 which is pushed open forward by the bottled product 3 being sent out and which normally closes the opening 7 to prevent cold air from leaking out to cool the stored bottled product 3. It is provided. On the other hand, the product take-out port 10 is provided with an outer flap 12 that opens inward so that the bottled product 3a in the bucket 9 can be taken out and prevents the inner flap 11 from opening due to this opening. This prevents the bottled product 3 from being stolen by illegal means such as inserting a hand or a stick through the product outlet 10.

However, in the above-mentioned theft prevention device, the bucket 9 for receiving the transported bottle product 3a must be provided outside the operating range of the outer flapper 12.
The falling distance of a is large, and therefore the impact received by the bottle product 3a is also large. In addition, the bottom position of the product delivery mechanism 2 is raised by the bucket 9, and the number of bottled products 3 stored therein is reduced. Furthermore, in order to arrange the bucket bag 9, the vicinity of the product takeout port 10 of the outer door 8 protrudes, resulting in several drawbacks to the vending machine equipped with this, such as the depth dimension of the vending machine becoming large.

The purpose of this invention is to eliminate the above-mentioned drawbacks at once, to reliably prevent theft of stored products, and to prevent theft of a vending machine that reduces the falling distance of products to be carried out, allows for a large number of stored products, and does not increase the depth dimension. The goal is to provide equipment.

According to the present invention, two sets of endless chains are vertically installed in parallel in a frame having a product outlet opening at the lower end, and a bridge is supported between the two sets of chains so that the chains can run. A product discharging mechanism is provided with a shelf board that descends in an elevator-like manner by means of an elevator, and a cylindrical product is placed and stored on the shelf board in a sideways position, and the chain is moved up and down by the movement of the chain. In a vending machine, the products on the board are dropped from the bottom through the product delivery port, the dropped products are caught by a shutter, and the products are delivered to the product delivery port that opens in the front outer door. Inside the outer door facing the exit,
A product take-out stage is provided whose installation height is approximately the same as the extension of the product transport surface of the shooter, and rotates in conjunction with the movement of the chain of the product delivery mechanism to remove products that have fallen from the product delivery mechanism. This is achieved by providing a semi-cylindrical product receiving tray which, after receiving the product, inverts and drops the product onto the shooter, so as to close the product delivery port of the product delivery mechanism.

Embodiments of the present invention will be described below based on the drawings. In the drawings of the embodiment, the same or common parts as in FIG. 1 are indicated by the same reference numerals.

In FIGS. 2 and 3, this vending machine includes a bottom bottle product 3 stored in a product delivery mechanism 2 disposed inside a main case 1, and a shutter that guides the bottle product 3 to a product takeout port 10. A semi-cylindrical product tray 21 according to the present invention is disposed between the container and the container 5. In the above-mentioned product delivery mechanism 2, two sets of endless chains 32 are connected to a drive sprocket 33 on a frame 31.
These two sets of endless chains 3
Bottled products 3 are placed on a shelf board 34 supported by a bridge between 2
At the same time, the chain 32 runs as the drive sprocket 33 rotates in the direction of the arrow A by a drive motor (not shown) in response to a sales command, and the shelf board 34 descends in an elevator style to pick up the bottle products 3 at the bottom. A so-called chain elevator type product delivery mechanism is adopted. The product delivery mechanism 2 includes a product delivery port 35 that opens at the lower end of the frame 31, and the product 3 is dropped and discharged through the product delivery port 35. The above-mentioned product tray 21 is provided facing the product delivery port 35 of the product delivery mechanism 2 so as to block the product delivery port 35, so that even if a hand or the like is inserted through the product delivery port 10, it will not reach the product delivery mechanism 2. Product delivery mechanism 2
is shielded from the product outlet 10. As shown in FIG. 4, the product receiving tray 21 is formed into a semi-cylindrical shape capable of receiving the bottled product 3 on the inside thereof, and is connected to a lower frame 31a of the product delivery mechanism 2 by a shaft 37 protruding from the side end. Rotatably supported on the shaft. Furthermore, this product tray 21 has a sprocket 3 attached to a shaft 37.
8 and a sprocket 39 mounted coaxially with the drive sprocket 33 are connected by a chain 40, and as the chain 32 runs, the arrow B
It is configured to rotate in the direction of.

On the other hand, inside the outer door 8, as shown in FIG. 2, in order to catch the bottled products 3 sliding on the shooter 5, a product removal stage 13 is installed instead of the conventional bucket 9 (FIG. 1). is provided. The stage 13 is provided so as to face the product take-out port 10, and its installation height is set to substantially match the extension of the product conveyance surface of the shooter 5.

Next, the operation and effect will be explained with reference to FIGS. 3 and 5. First, in the sales standby state, the product tray 21 is in a horizontal position facing downward, blocking the product delivery port 35, and stealing the bottled product 3 by illegal means such as inserting a hand or a stick through the product removal port 10 (FIG. 2). This is prevented. Next, when transporting the product,
When the chain 32 starts to travel in response to a sales command, the product receiving tray 21, which was in the state shown in FIG.
When the product receiving tray 21 is in the state shown in FIG.
The product falls into the product tray 21. The product receiving tray 21 that has received the dropped bottle product 3 continues to rotate and causes the bottle product to fall onto the shooter 5 below in the state shown in FIG. 5C. Then, it continues to rotate further and returns to the original state shown in FIG. 5C. During this time,
The chain 32 also continues to run, and the next bottle product 3 descends to the initial position of the bottom bottle product 3 and stops.

On the other hand, the bottle product 3 that has fallen onto the shooter 5 slides on the shooter 5 and heads toward the product take-out port 10, and as shown in FIG. In this way, since the product is configured to be received by the product take-out stage 13 whose installation height is approximately the same as the extension of the product conveyance surface of the shooter 5, the conventional bucket tray 9
(Fig. 1), the falling distance of bottled products is smaller, and the product outlet portion of the outer door 8 does not protrude forward.

FIG. 6 is a diagram showing a different embodiment, and corresponds to FIG. 3 showing the sales standby state of the above-mentioned embodiment. The difference from the first embodiment is that the product tray 2 is in the sales standby state.
In response to the sales command, the product operates from the state shown in FIG. 5B in the above explanation to the state shown in FIG.
The state returns to the state shown in Figure 5B. In this configuration, the time from when a sales command is issued until the bottled product is taken out to the bottled product outlet 10 (FIG. 2) is significantly shortened.

As described above, according to the present invention, a semi-cylindrical product tray that rotates in conjunction with the operation of the product delivery mechanism is provided so as to block the product delivery port of the product delivery mechanism, and is not stored in the sales standby state. In addition to shielding the product and the product delivery mechanism from the product take-out port, when taking out the product, the product that has fallen from the product delivery mechanism is caught, and then reversed to allow the product to fall onto the shutter. The vending machine is equipped with a product take-out stage whose installed height is approximately the same as the extension of the product conveyance surface of the shooter, and is configured to receive products sliding on the shooter on this stage. Theft of stored products is reliably prevented by preventing the stored products and the product delivery mechanism from being touched through the product take-out port, and as is clear from Figure 2, the fall distance of the products to be delivered is short and the impact received by the products is reduced. The product delivery mechanism can be extended downward to increase the number of products stored, and the outer door does not have a protrusion, allowing for a small depth dimension.
