  However, in most vending machines, some temperature unevenness occurs in the product storage. For this reason, simply managing the number of products remaining before product replenishment and the elapsed time after product replenishment as in the conventional vending machine, for example, when selling products with a narrow range of suitable temperatures, it is not in an optimal temperature state. There is a risk that the product will be sold.

  Accordingly, an object of the present invention is to provide a vending machine capable of suppressing the sale of a product that is not in an appropriate temperature state even when a product having a narrow range of appropriate temperatures is sold.

According to one aspect of the present invention, a vending machine that sells goods by cooling or heating is provided. The vending machine is disposed in a product storage box having a heat insulating structure, and includes a product storage device having a plurality of product storage columns each storing a plurality of the products, and a plurality of the product storage columns. The number of permitted sales of the product is set for each of the products, and the number of permitted sales of the corresponding product storage column is decremented by 1 each time one of the products is sold, and the number of permitted products stored is 0. And a control unit for stopping the sale of the commodity stored in the column. Here, the control unit is configured to increment the sales permission number of the corresponding product storage column by 1 when a predetermined time elapses after the sale of the product. Further, the vending machine has an outside air temperature detecting unit that detects an outside air temperature, and the control unit is configured to set the number of sales permits based on the outside air temperature detected by the outside air temperature detecting unit. Is done.

  In the vending machine, the number of sales permits is set for each product storage column, and each time one product is sold, the corresponding number of sales permits is decremented by 1, and the number of sales permits becomes 0. The sale of the products stored in the store is stopped. For this reason, by appropriately setting the number of sales allowances, it is possible to suppress the sale of products that are not in an appropriate temperature state even when products with a narrow range of appropriate temperatures are sold.

Is provided. The said product carrying-out apparatus is comprised so that the container-containing drink P in the goods storage column in which it was provided may be sequentially carried out from the container-containing drink P located in the lowest part. The sold-out detection device is configured to detect that the beverage P in the container has disappeared or the remaining amount (for example, the remaining one) has become small in the product storage column in which the sell-out is provided.

  A product shooter 11 is provided below the product storage device 3 in the product storage 2. The merchandise shooter 11 is formed of a flat plate-like member having a large number of air holes, and is inclined so as to descend from the back side of the vending machine 1 toward the front side. The merchandise shooter 11 guides the beverage P in the container carried out by the merchandise carry-out device to the merchandise outlet 9 a formed in the outer door 9 through the merchandise outlet 10 a formed in the inner door 10.

  An in-compartment heat exchanger (evaporator) 12 and an in-compartment blower fan 13 are provided in the lower part of the commodity storage 2, more specifically, below the commodity shooter 11. The internal blower fan 13 passes the air in the product storage 2 through the vicinity of the internal heat exchanger 12 and circulates through the back duct 14 disposed on the back side in the product storage 2. A compressor 16, an external heat exchanger (condenser or gas cooler) 17, and an expansion mechanism (capillary tube) 18 are disposed in the machine room 15 below the product storage 2.

  The internal heat exchanger 12, the compressor 16, the external heat exchanger 17, and the expansion mechanism 18 are connected by a refrigerant pipe 19 that circulates the refrigerant, and in the vicinity of the external heat exchanger 17, the external heat An external fan 20 for blowing air to the exchanger 17 is disposed. Then, the product storage 2 is connected by the internal heat exchanger 12, the compressor 16, the external heat exchanger 17, the expansion mechanism 18, the internal air fan 13, and the external air fan 20 connected by the refrigerant pipe 19. A cooling device 30 for cooling the inside is configured.

  Further, the vending machine 1 includes a first temperature sensor 41 that detects the temperature in the commodity storage 2, a second temperature sensor 42 that detects the outside air temperature, a door switch 43 that detects the open / closed state of the outer door 9, and the like. Various detection sensors are provided. In this embodiment, the 1st temperature sensor 41 is installed in the bottom part of the goods storage apparatus 3, or its vicinity, and detects the lower temperature T1 in the goods storage 2. As shown in FIG. The installation positions of the second temperature sensor 42 and the door switch 43 are not particularly limited, but the second temperature sensor 42 is installed, for example, on the upper side of the vending machine 1, and the door switch 43 is installed, for example, on the outer door 9.

  In addition, although illustration is abbreviate | omitted, on the front surface of the outer door 9, the coin insertion slot into which a coin and a banknote are thrown in, and the various container-containing drinks P accommodated in each merchandise storage column 4-8 of the merchandise storage apparatus 3. A product selection button for selecting, a product information display unit for individually displaying information on various types of container-containing beverages P stored in the product storage columns 4 to 8 of the product storage device 3, and the like are provided. In addition, an input unit such as a remote controller on which the serviceman or the like performs various settings and inputs is installed inside the outer door 9.

  The operation of the vending machine 1 is controlled by a control unit (control unit) 50. Hereinafter, some of the operation control of the vending machine 1 by the control unit 50 will be described.

  When a predetermined amount of money is inserted from the money insertion slot and one of the product selection buttons is pressed, the control unit 50 drives the product delivery device of the corresponding product storage column to carry out the beverage P in the container. Let

  In addition, when the sold-out detection device detects that the beverage P in the container is sold out, the control unit 50 displays information (in this case, “sold out”) on the corresponding product information display unit.

  Moreover, the control unit 50 operates the cooling device 30 so that the temperature in the product storage case 2 maintains the set temperature TS during the operation of the vending machine 1. For example, the control unit 50 reads the lower temperature T1 in the product storage 2 detected by the first temperature sensor 41 at a predetermined period, and when the lower temperature T1 exceeds the upper limit value of the set temperature TS, When the fan 13, the compressor 16 and the external blower fan 20 are actuated to cool the inside of the product storage 2 and the lower temperature T1 is lowered to the lower limit value of the set temperature TS, the actuated internal blower fan 13 and the compressor are actuated. 16 and the external fan 20 are stopped.

  The control unit 50 temporarily stops selling the beverage P contained in the product storage device 3 immediately after the vending machine 1 is started and immediately after the supply of the beverage P contained in the product storage device 3. (Stop) For example, the control unit 50 receives information indicating completion of replenishment of the beverage P in the container until the first predetermined time elapses after the power supply of the vending machine 1 is turned on, and the outer door 9 is Until the second predetermined time elapses after being closed, the sale of the beverage P in the container stored in the product storage device 3 is stopped, and the corresponding product information display unit is in a sales stop state. (In this case, “in preparation”) is displayed. When the first predetermined time elapses after the power of the vending machine 1 is turned on or when the second predetermined time elapses after the outer door 9 is closed, the control unit 50 releases the sales stop state, While clearing the “preparing” display in the product information display unit, the sale of the beverage P in the container stored in the product storage device 3 is started or resumed. The first predetermined time and the second predetermined time are set in advance as a time during which the inside of the product storage 2 can be sufficiently cooled by the cooling device 30, and the first predetermined time = the second predetermined time. Also good.

  Here, in this embodiment, the goods storage 2 is comprised so that it can function as a supercooling chamber which can cool the drink P in a container to a supercooled state. When the serviceman or the like inputs information indicating that the product storage 2 functions as the supercooling chamber via the input unit, the set temperature TS in the product storage 2 sets the beverage P in the container to a supercooled state. Is set to the temperature to be Specifically, the set temperature TS is a temperature equal to or lower than the freezing point of the beverage P in the container, and is set to, for example, around −5 ° C. (about −2 to −8 ° C.).

  Thus, the set temperature TS in the product storage 2 when the product storage 2 functions as the supercooling chamber is lower than that of a conventional general vending machine, and the range is narrow. Become. In other words, the appropriate temperature range or the allowable temperature range of the beverage P in the container as a product is narrower than before. For this reason, it is difficult to always maintain the temperature of the entire product storage 2 at the set temperature TS, and the temperature of a part of the product storage 2 (for example, the upper space) may deviate from the set temperature TS. is there. Therefore, just by managing the remaining number of the beverages P in the container P before replenishment and the elapsed time after the replenishment of the beverage P in the container, as in the prior art described above, Then, there exists a possibility that the containered drink P which is not in a supercooled state may be sold.

  Therefore, when the product storage 2 is caused to function as the supercooling chamber, the control unit 50 performs processing described below (each product storage) in order to prevent a situation where the beverage P in a container that is not in the supercooled state is sold. A process for setting the number of sales permits for the columns 4 to 8 and a process for selling the container-containing beverage P for each product storage column are executed.

(Setting processing of the number of sales permits for each product storage column 4-8)
The control unit 50 sets the sales permission number NA of the beverage P in the container for each of the plurality (five) of product storage columns 4 to 8 included in the product storage device 3. This sales permission number NA is the number of container-containing beverages P placed in the atmosphere of the set temperature TS in each of the product storage columns 4 to 8, specifically, each product including the container-containing beverages P located at the bottom. It is the number of beverages P in a container located on the lower side of the storage columns 4-8. Therefore, each sales permission number NA becomes a value smaller than the number (maximum storable number) of the container-containing beverages P that can be stored in the corresponding product storage column. The sales permission number NA may be different for each of the product storage columns 4 to 8, or may be the same for all or some of the product storage columns 4 to 8.

  FIG. 3 is a flowchart illustrating an example of a process for setting the sales permission number NA of each of the product storage columns 4 to 8. This flowchart is executed, for example, when the sale of the container-containing beverage P stored in the product storage device 3 is started and / or restarted.

In step S1, the previous value of the sales permission number NA of the beverage P in the container is cleared.
In step S2, the outside air temperature is read.
In step S3, the sales permission number NA of each of the product storage columns 4 to 8 of the product storage device 3 is set based on the outside air temperature read in step S2. For example, the control unit 50 refers to the setting table in which the outside air temperature, the identification information (column A to column E) of the product storage columns 4 to 8 and the sales permission number NA are associated with each other as shown in FIG. The sales permission number NA is set in the storage columns 4-8. The setting table can be created in advance based on experiments or the like. The sales permission number NA is set to a value smaller in the front product storage column than in the rear product storage column. Further, the sales permission number NA of each of the commodity storage columns 4 to 8 is basically set to a smaller value as the outside air temperature is higher.

(Sales processing of beverages P in containers for each product storage column)
Each time one beverage P in a container stored in the product storage device 3 (in the product storage 2) is sold, the control unit 50 sells the corresponding product storage column NA, that is, the sold container. The sales permission number NA of the product storage column in which the beverage B is stored is decremented by one. Further, the control unit 50 starts counting a predetermined time set in advance every time one beverage P in a container is sold, and when the counting of the predetermined time is completed, that is, after selling the beverage P in the container, When the predetermined time has elapsed, the sales permission number NA of the corresponding product storage column is incremented by one. The predetermined time is appropriately set depending on the volume and structure of the commodity storage 2, the performance of the cooling device 30, and the like, and can be set to 1 to 2 hours, for example.

  Then, the control unit 50 stops the sale of the container-containing beverage P stored in the product storage column whose sales permission number NA becomes 0, and at the same time, the corresponding product information display unit, that is, the sales permission. “Preparing” is displayed on the product information display section for displaying information about the container-containing beverage P stored in the product storage column whose number is zero. In addition, when sold-out of the drink P with a container is detected, the control unit 50 displays "sold out" on the corresponding said merchandise information display part as mentioned above.

  FIG. 5 is a flowchart showing an example of a sales process of the beverage P in the container. This flowchart is executed for each of the product storage columns 4 to 8 after the sales permission number NA of each of the product storage columns 4 to 8 is set. Although the sales process of the container-containing beverage P stored in the product storage column 4 will be described here, the same applies to the sales process of the container-containing beverage P stored in the other product storage columns 5-8.

  In step S11, it is determined whether or not the container-containing beverage P stored in the product storage column 4 has been sold. When the packaged beverage P is sold, the process proceeds to step S12, and when the packaged drink P is not sold, the process proceeds to step S13.

  In step S12, the sales permission number NA is decremented by 1 (NA ← NA-1), and the timer is started to start measuring the predetermined time. Here, the predetermined time is counted every time one beverage P in a container is sold. For this reason, when a plurality of containerized beverages P are sold within a time interval shorter than the predetermined time, the same number of timers as the containerized beverages P sold are activated.

  In step S13, it is determined whether or not there is the timer that has finished counting the predetermined time, that is, whether or not the predetermined time has elapsed after the sale of the beverage P in the container. If there is the timer that has finished counting the predetermined time, the process proceeds to step S14, and the number N1 of sales permission is incremented by 1 (NA ← NA + 1). Proceed to

  In step S15, it is determined whether or not the sales permission number NA (including the value decremented in step S12 and / or the value incremented in step S13) is zero. When the sales permission number NA is 0, the process proceeds to step S16, and when the sales permission number NA is not 0 (when the sales permission number NA is 1 or more), the process proceeds to step S18.

  In step S16, it is determined whether or not the sale of the beverage P in the container is in a stopped state. When the sale of the beverage P in the container is stopped, the process returns to step S11. On the other hand, if the sale of the beverage B in the container is not stopped, the process proceeds to step S17, the sale of the beverage P in the container is stopped, and the corresponding product information display section, that is, the product storage column 4 “Preparing” is displayed on the product information display unit that displays information about the beverage P contained in the container.

  In step S18, as in step S16, it is determined whether or not the sale of the beverage P in the container is stopped. When the sale of the beverage P in the container is not stopped, the process returns to step S11. On the other hand, when the sale of the beverage P in the container is stopped, the process proceeds to step S19, the sale of the beverage P in the container is resumed, and the “preparing” display in the corresponding product information display unit is cleared. Then, the process returns to step S11.

  As described above, in the present embodiment, the control unit 50 sets the sales permission number NA of the container-containing beverage P for each of the plurality of product storage columns 4 to 8, and one container-containing beverage P is sold. Each time, the sales permission number NA of the corresponding product storage column among the plurality of product storage columns 4 to 8 is decremented by one. Then, the control unit 50 stops the sale of the container-containing beverage P stored in the product storage column whose sales permission number NA is 0, and stores the product whose sales permission number NA is 0. “Preparing” is displayed on the product information display section that displays information about the beverage P in the container stored in the column. Here, as described above, the sales permission number NA is the number of the beverages P contained in the container in the atmosphere of the set temperature TS in the commodity storage 2. For this reason, it is suppressed that the drink P with a container which is not in a suitable temperature state (namely, not in a supercooled state) will be sold.

  Further, the control unit 50 starts counting the predetermined time every time one beverage P in the container is sold, and when the counting of the predetermined time is completed, that is, the predetermined time from the sale of the beverage P in the container. When the time has elapsed, the sales permission number NA of the corresponding product storage column is incremented by one. When the container-containing beverage P is sold, a new container-containing beverage P is placed in an atmosphere of the set temperature TS instead of the container-containing beverage P. And this new container-packed drink P will be in a supercooled state or a state close | similar to it after a certain amount of time passes in the atmosphere of preset temperature TS. For this reason, it becomes possible to sell more beverages P in a container while preventing the beverages P in a container that is not in an overcooled state from being sold.

  Further, the control unit 50 sets the sales permission number NA of each of the plurality of product storage columns 4 to 8 based on the outside air temperature. For this reason, an appropriate number of permitted sales NA according to the outside air temperature is set, and it is effectively suppressed that the beverage P in the container that is not in the supercooled state is sold.

  Here, in the above-described embodiment, the control unit 50 reads the outside air temperature when the sale of the container-containing beverage P stored in the product storage device 3 is started or restarted, and each of the control units 50 based on the read outside air temperature. The sales permission number NA of the product storage columns 4 to 8 is set (see FIG. 3). However, it is not limited to this. The control unit 50 continuously monitors the outside air temperature, and based on the previous day's maximum temperature, average temperature, temperature in the same time zone, or temperature change per fixed time immediately before, each of the commodity storage columns 4-8. The sales permission number NA may be set. Such a case is also included in “setting the sales permission number NA of each product storage column based on the outside temperature”.

  Further, the control unit 50 reads the outside air temperature regularly or at any time during execution of the sales process (FIG. 5) of the packaged beverage P, and permits the sales of each of the product storage columns 4 to 8 based on the read outside air temperature. The number NA may be corrected. For example, the control unit 50 corrects the sales permission number NA (including the decrement and / or incremented sales permission number NA) when the outside air temperature increases, and decreases the sales permission number NA (decrement and / or when the outside temperature decreases). (Incremented sales permission number NA is included).

  Further, the control unit 50 may set the sales permission number NA of each of the product storage columns 4 to 8 based on an input operation to the input unit by the serviceman or the like. For example, when the service person or the like refills the product storage device 3 with the container-containing beverage P, information indicating the sales permission number NA of each product storage column 4 to 8 is input via the input unit, and the control unit 50 sets the sales permission number NA of each of the commodity storage columns 4 to 8 based on the inputted information.

  As described above, when the sales permission number NA of each of the product storage columns 4 to 8 is set based on the input operation by the serviceman or the like, the serviceman or the like, for example, of each of the product storage columns 4 to 8 based on the outside temperature. The sales permission number NA can be determined. However, it is more preferable that the service person or the like can determine the sales permission number NA of each product storage column 4 to 8 based on the actual temperature state in the product storage 2.

  Therefore, a temperature detection member whose appearance changes according to the ambient temperature may be installed in the product storage 2 so that the service person can easily grasp the actual temperature state in the product storage 2. . The temperature detection member is not particularly limited, but is, for example, a reversible temperature indicating material whose color changes according to temperature, preferably a tape-shaped temperature indicating material having reversibility. Preferably, as shown in FIG. 6, when the outer door 9 is opened, a portion of the product storage device 3 that is exposed immediately above the inner door 10 (for example, a frame portion that configures the product storage columns 4 to 8). One or a plurality of temperature indicating materials 61 are attached in the vertical direction. If it does in this way, the said service person etc. will be the temperature of the container-containing drink P mainly located in the upper side among the container-containing drinks P stored in each goods storage column 4-8, when the outer door 9 is open | released. The state can be visually confirmed, and along with this, it is possible to grasp or estimate the number of bottled beverages P in an appropriate temperature state. Therefore, the service person or the like can easily and accurately determine the sales permission number NA of each of the commodity storage columns 4 to 8.

  In addition, such a temperature detection member (the temperature indicating material) is installed not only in the product storage 2 that functions as the supercooling chamber, but also in a normal product storage, that is, a refrigerated room for cooling the beverage P in the container, Of course, it may be performed with respect to the goods storage which functions as a warming room which heats the drink P with a container. In this way, the service person or the like can adjust the set temperature in the product storage after visually confirming the actual temperature state in the product storage. The contained beverage P) can be cooled or warmed more appropriately.

  Moreover, in the above-mentioned embodiment, the time preset as the said predetermined time which the said timer measures after sale of the drink P with a container is used. However, the present invention is not limited to this, and the predetermined time may be variably set based on the outside air temperature or the like. In this case, for example, in step S3 of FIG. 3, the control unit 50 may set the sales permission number NA for each of the product storage columns 4 to 8 and set the predetermined time. The predetermined time is set longer as the outside air temperature is higher.

  Furthermore, in the above-described embodiment, the commodity storage 2 functions as the supercooling chamber. However, it is not limited to this. The product storage 2 may function as the cold storage room or the heating chamber. In this case, the temperature variation of the beverage P in the container to be sold can be greatly reduced. In addition, when functioning the product storage 2 as the heating chamber, a heating device such as a heater is provided in the product storage 2 instead of the cooling device 30, and the control unit 50 adjusts the temperature in the product storage 2. What is necessary is just to comprise so that operation | movement of the said heating apparatus may be controlled based on.

  As mentioned above, although embodiment of this invention and its modification were demonstrated, this invention is not limited to the above-mentioned embodiment and modification, Further deformation | transformation and change are possible based on the technical idea of this invention. Of course. For example, although the above-described embodiment and its modification are directed to vending machines that use a beverage P in a container as a product, the present invention sells a product other than the beverage P in a container by cooling or heating it. It is also applicable to the machine.
