Description

[Detailed Description of the Invention] The present invention relates to an improved product storage device for a vending machine.

As shown in FIG. 1, the conventional product storage device of this type of vending machine generally includes an inner box 103 inside the main body 101 that is protected from the heat insulating wall 102, and a serpentine-shaped stocker 104 is provided in the inner box 103. All products (for example, canned drinks) F are simultaneously supported in the inner box 103 by the stocker 104 and heated or cooled by the heater 105 or the cooler 106.

Therefore, in this case, all the products F supported in the stocker 104 are heated or cooled at the same time, so the last products that take a considerable amount of time to be sold are heated or cooled from the beginning, which results in wasted energy. It had become.

This problem was even more noticeable in locations where sales were slow, and improvements were needed.

The present invention has been devised in view of the drawbacks of conventional vending machines, and one embodiment thereof will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic side sectional view of an embodiment of a vending machine according to the present invention, in which 1 is the main body of the vending machine, 2 is an inner box provided in the main body 1, and a partition wall 2' The main storage part 2A is divided into a lower main storage part 2A and an upper auxiliary storage part 2B, and the main storage part 2A is covered with a thick and large heat insulating material 3 with a large heat insulation effect on the circumference, and the front lower end part is provided with a product discharge port 4 connected to a sales port (not shown) on the front surface of the main body 1,
A heater 5, a cooler 6, and a blower 7 that can be selectively driven are provided at the lower end of the interior.

Further, the auxiliary storage section 2B is provided with a thin heat insulating material 8 having a small wall thickness and having a small heat insulating effect on the circumferential surface except for the bottom surface.

Reference numeral 10 designates a main product stocker, the majority of which is located within the main storage section 2A, and its upper end facing into the auxiliary storage section 2B through a hole 9 provided in the partition wall 2' of the inner box 2. There is.

This product stocker 10 has two stocker components 10.
It is constructed by combining A and IOB, and these stocker components 10A and IOB are made by vacuum forming synthetic resin such as plastic.
As shown in FIGS. 3 and 4, a meandering product storage passage 13 is formed on the inner surface of the side plate 11 by a portion 12 that is bulged on both sides of the inner surface of the side plate 11.
2 has a hollow structure hollowed out from the outer surface of the side plate portion 11 in order to reduce cost and weight.

Both stocker structures 10A configured in this way,
Both IOBs are on their inner surfaces, that is, the product storage passage 1
spacer 14.3 such that the surfaces having spacer 14.3 face each other with an appropriate distance apart. The main product stocker 10 has a serpentine shape and is arranged side by side through the above-mentioned products and is integrally fixed by appropriate means to accommodate the product F in a removable manner through both product storage passages 13, and , are installed in the main and auxiliary storage sections 2A and 2B in this state as described above.

Another thing to note about this main product stocker 10 is that expanded heat insulating protrusions 15a and 15b are provided on both the outer and inner surfaces of each stocker structure 10A and IOB at locations corresponding to the above-mentioned holes 9 in the portion 12. The heat insulating protrusion 15a on the outer surface comes into contact with the edge 9' of the perforation 9 and is effective in blocking air circulation between the two storage sections 2A and 2B, and the heat insulating protrusion 15b on the inner surface abuts against the edge 9' of the perforation 9. In other words, it is configured so that it comes into contact with the heat insulating protrusion 15b of the opposing stocker structure, thereby effectively blocking air flow between the storage sections 2A and 2B through the interior of the main product stocker 10.

Reference numeral 16 denotes an auxiliary product stocker installed in the auxiliary storage section 2B, which is composed of several fence plates 16A arranged vertically and sloped downward in the same direction. The lower ends of each of them face a vertical common chute 17 formed between the inner surface of the auxiliary storage section 2B.

This common chute 17 has its lower end communicated with the product storage passage 13 through a receiving opening 13' formed at the upper end of the main product stocker 10, and has the respective fence plates 16A, . . .
The product F that has been rolling and falling is guided to the product storage passage 13.

In the present invention, the amount of products to be stored in the main product stocker 10 and the auxiliary product stocker 16 is intended to be smaller than the latter.

It goes without saying that the invention is not limited to this, but 18 is a carry-out machine installed at the lower end of the main product stocker 10 in the main storage section 2A, and is used to move the goods in the product storage passage 13 based on a carry-out signal or the like. The products are guided one by one to the product discharge port 4 through an unloading guide 19.

20 is a lid plate that always closes the product discharge port 4 due to its own weight or spring, and the product F is inserted into the product discharge port 4 as described above.
When it is carried out, it pivots under the weight of the product F, which it refuses, and warns to open the product discharge port 4.

As will be described later, each fence plate 16A of the auxiliary product stocker 16 is provided on the front side of the auxiliary storage section 2B.
・It has a filling port (not shown) for filling the product F into the container.

Since the present invention is configured as described above, when the heater 5 or the cooler 6 is driven, the hot air or cold air is circulated only within the main storage section 2A by the blower 7, and the air is circulated through the main storage section 2A. Only the product F in the product stocker 10 is heated or cooled.

Then, when the unloader 18 is driven in response to a sales signal, etc., the product F1 on the bottom row, which has undergone sufficient heat exchange, is unloaded.
The product is discharged to the sales port of the main body 1 through the guide 19 and the product discharge port 4.

On the other hand, as the product F1 is carried out, all the products F, . The products are transferred and dropped into the main product stocker 10 through the common chute 17 and the receiving port 13'.

Then, the product Fn in the main product stocker 10, which has newly arrived from the auxiliary storage section 2B side to the main storage section 2A side due to the rolling fall of the products F, . state.

During operation of such a vending machine, the hot or cold air in the main storage section 2A flows into the product storage passage 13 of the main product stocker 10.
Although a small amount of air flows into the auxiliary inner box 8 through the gap formed by the auxiliary inner box 8, this is unavoidable. Since it is covered with material 3, there is no leakage to the outside.

The present invention, as shown in Narukami, is that the inner box installed inside the main body of the vending machine is separated by a partition wall to create a main storage area and an auxiliary storage area, and this main storage area is equipped with a heat exchanger such as a heater or cooler. A main product stocker and an auxiliary product stocker are provided in the main storage section and the auxiliary storage section, respectively, and these stockers are connected through a hole provided in the partition wall, and the main product stocker Since the products carried out in sequence are guided to the sales port provided in the main body through the product discharge port provided in the main storage section, all stored products are not heated or cooled at the same time. Heat exchangers such as coolers can be of small capacity and can be manufactured at low cost, and energy consumption can be minimized.

Furthermore, since the number of products located in the main storage section can be reduced, it is extremely meaningful that only the products necessary for sale can be rapidly heat-exchanged immediately after a vending machine is installed or immediately after a power outage.
