DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine for cooling or heating products such as cans and bottled beverages and selling them as cold or hot products.

[0002]

2. Description of the Related Art As a vending machine for cans and bottles, a vending machine represented by a serpentine vending machine is known. This serpentine type vending machine is equipped with a top tray for product introduction at the upper end of each column and a product unloading mechanism (bend mechanism) at the lower unloading end in a cabinet of a cabinet serving as an insulated housing. Storage racks that stack and store products in a row in the upper and lower rows, and products that are equipped with a cooling or heating device for products that are arranged at the bottom of the warehouse, and that are arranged at the bottom of the columns from the product storage racks by the operation of the product unloading mechanism based on the sales order Are dropped and carried out one by one and sent out to a product outlet.

On the other hand, in recent years, the capacity of vending machines (the number of stored products) has been increasing in order to increase the efficiency of routes by minimizing the trouble of replenishing products by circulating through vending machines installed at each location. On the other hand, it is important to reduce the power consumption of vending machines and promote energy saving. In addition, depending on the type of beverage product, if the content is heated for a long period of time, the quality of the content beverage may deteriorate, and countermeasures have become one of the issues.

In order to solve the above-mentioned problem, the present inventors divided a product storage rack housed in a cabinet of a vending machine into upper and lower parts, and provided a shutter device as a heat insulating partition in the middle. The products placed in the lower rack area are interposed and are cooled or heated by a cooling or heating device arranged at the bottom of the refrigerator, so that the upper rack area is at room temperature compared to the lower rack area. We have been developing vending machines that can be used as a close stock space and that replenish products from the upper area of the rack to the lower area in accordance with the product unloading operation from the lower area accompanying product sales. .

On the other hand, a vending machine having a configuration related to the above-mentioned system has been known as Japanese Patent Application Laid-Open No. Hei 10-91855. In this known vending machine, a shutter device having a heat insulating structure for partitioning the inside of the rack into an upper region and a lower region to be cooled or heated is attached to a product storage rack housed in a product storage, and the shutter is provided. The apparatus includes an automatic return-type heat-insulating shutter that opens by the weight of the product and allows the product to pass therethrough, and the heat-insulating shutter that moves the product in the upper region according to the operation of the product unloading device provided at the lower end of the product storage rack. A product delivery device for discharging the product from the lower region by the product delivery device, and at the same time, or with a short delay, the product delivery device in the upper region to operate the product delivery device. , The product is sent to the lower region through the shutter device.

[0006]

By the way, in a serpentine can vending machine or the like, generally, a multi-selection product storage rack is mounted in a warehouse to sell various kinds of beverage products in parallel. Each column stores different types of products by column. On the other hand, the number of products sold by vending machines varies depending on the vending machine installation location (season), season, customer base, and the like. Is fast (the number of sales per hour is large), but the less popular products are sold less frequently and the in-flight storage time before being sold becomes longer.

Therefore, considering the energy saving of the vending machine and the preservability of the product (especially hot products), it is necessary to store the product in the cooling and heating area of the product storage rack and keep the product at the appropriate temperature for sale and cool. The number of inventories depends on the location of the vending machine,
In addition to seasonal conditions, the best-selling products and the less popular products will naturally differ. In this regard, in the vending machine disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 10-91855, the product is sent from the upper region to the lower region each time the product is carried out from the lower region for cooling or heating the product. Like that. Therefore, for each column in the upper area of the product storage rack, or more precisely, for each column in the upper area of the rack, while the product remains in the column, the column in the lower area corresponding to this column is always full of the product. It will be stored in.

[0008] However, in consideration of the above-mentioned appropriate stock quantity of commodities in the cooling / heating area, the merchandise storage rack can be used irrespective of whether the merchandise is fast-selling (sell-good merchandise) or slow-selling (low-popular merchandise). If the lower area is full, the heat load on the cooling / heating device is increased and the power consumption is increased. In addition, particularly in the case of a hot commodity whose sales turnover is low, it takes a long time until the products arranged in the upper part of the lower area are sold. It remains exposed to the heated state for a time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to solve the above-mentioned problems by enabling energy-saving and fine-grained inventory management of products in a machine in consideration of product preservability. Another object of the present invention is to provide a vending machine that can simplify the in-machine adjustment work in accordance with a change in a product to be sold.

In this state, when the product 14 is put on the top tray 7 from the front of the cabinet 1, the product 14 rolls on the top tray 7 and enters the column of the upper rack portion 6A from the rear end, and its meandering shape is obtained. After moving down the product path, the heat insulating shutter 8c of the shutter device 8 is pushed open to move into the lower rack portion 6B, where it is stacked and stored in the rack. The products that have entered the lower rack section 6B in this process are counted by the control section via the detection switch 11, and when the number of articles stored in each column of the lower rack section 6B reaches a predetermined number, a command from the control section is issued. Then, the product delivery mechanism 12 of the upper rack 6A is reset, the flapper protrudes into the product path, and locks and holds the subsequent product supplied through the top tray 7. It is to be noted that the introduction of the product is performed until the upper rack section 6A and the top tray 7 are full.

Next, when the vending machine is put into operation, the cooling / heating unit 4 is operated in a designated mode, and cool air or warm air that has exchanged heat with the cooler 4a or the heater 4b is supplied to the inside of the refrigerator by the fan 4c. The products 14 stored in the lower rack portion 6B of the product storage rack 6 are kept cool or heated by circulation ventilation. The operation of the cooling / heating unit 4 is controlled based on the set temperature in the refrigerator, as in a normal vending machine. Further, in this case, since the heat insulating shutters 8c of the shutter device 8 are closed, the cool air and the warm air circulate only through the region of the lower rack 6B to actively cool or heat this region. And the upper rack 6
The area A is blocked by the shutter device 8 so that cool air and warm air do not flow through, so that the temperature of the area A is kept close to room temperature as compared with the area of the lower rack 6B.

On the other hand, when the merchandise is sold, the merchandise unloading mechanism 9 mounted on the designated column of the lower rack 6B is operated based on the sales command from the control unit, and the merchandise 1 arranged at the bottom is arranged.
4 is dropped and carried downward, and is sent out to the product take-out port 2a via the product take-out shooter 5. Then, when the stock quantity of the goods stored in the column of the lower rack 6B decreases with the progress of the sale of the goods, the goods delivery mechanism 12 of the upper rack 6A operates according to the goods supply command from the control unit, and the upper rack 5 The required number of the products 14 stocked in 6A are sequentially sent out. The commodity 14 sent out by this operation falls on the shutter device 8, pushes open the heat insulating shutter 8c, moves into the lower rack portion 6B, and is supplied.
Further, when the product 14 enters the lower rack 6B, the product detection switch 11 is operated and its signal is taken into the control unit and counted. The heat-insulating shutter 8c closes again after the commodity has passed to close the shutter passage.

In this case, the control unit sends the commodity sending mechanism 12
Is issued as follows, for example. That is, the inventory quantity of products always stored in the lower rack section 6B for each column of the product storage rack 6 is determined by setting the vending machine installation location, season, customer base, product type, cold and hot products at the appropriate sales temperature. It is set in advance by taking into account the time required for cooling and heating, and the residence time in the rack until the hot product is sold (hot products degrade the quality of the content beverage if heated for a long time). Are input to the control unit. When the number of articles in the column of the lower rack section 6B becomes smaller than the set stock quantity, the control section outputs an article supply command to the column.

Alternatively, the control unit monitors the sales situation of the product for each column of the product storage rack 6 (for example, counts the number of units sold per specified time), and based on this data, the lower rack unit 6B To determine the appropriate number of stocks to be always stored in the lower rack 6B at that time
And outputs a product replenishment command at an appropriate timing by comparing the actual number of products in stock with the appropriate number of stocks.

As a result, fine inventory management can be achieved for the lower rack portion 6B of the product storage rack 6 so as to maintain an appropriate stock quantity determined according to the type of the product stored here for each column, In addition to energy saving, it is possible to prevent deterioration of the quality of the content beverage due to long-time heating of hot products. Also, as compared with a system in which the lower rack portion 6B is always filled with a product, in terms of energy saving effect, the heat load of the cooling and heating devices is reduced, so that power consumption can be reduced, and sales turnover is low. Even for hot products (low-popular products), by setting the appropriate stock quantity to be smaller than the storage capacity of the lower rack section, the residence time for heating until actually sold is shortened, and Quality deterioration can be prevented.

In the illustrated embodiment, a serpentine type product storage rack is shown as a product storage rack. However, the present invention is not limited to a serpentine type product storage rack, but other vertically stacked type product storage racks. Needless to say, the present invention can also be applied to practice.
