  The manual switches S1a and S2a are made up of an a contact that automatically returns, and are provided on the emergency power supply line 25. Then, by being manually operated by an operator at the time of a power failure of the commercial power supply, the power from the emergency power supply 11 is supplied to the power supply unit 10 while being manually operated. Moreover, the push button 55 for operating manual switch S1a, S2a is provided in the preliminary installation space of the money sorter 15 of the vending machine 1, as shown also in FIG. In recent years, with the spread of electronic money, there are many vending machines that have a spare installation space for installing an IC card read / write device, and the installation space has been standardized, and manual switches S1a and S2a are installed. If it is provided in a case corresponding to the space, it can be installed in almost all vending machines without modification.

  Next, based on the function of each component described above, the operation of the vending machine 1 according to this embodiment will be described.

  FIG. 3 is a diagram illustrating the normal operation of the vending machine 1 according to the present embodiment, FIG. 4 is a diagram illustrating the operation during a power failure, and FIG. 5 is a diagram illustrating the operation when an earthquake occurs and during a power failure.

  As shown in FIG. 3, when commercial power is supplied to the vending machine 1 according to the present embodiment, the power failure detector X is energized from the plug 23 through the primary power supply line 24 to constitute the power failure detector X. Is excited (S0). Then, the first contacts X1c and X2c interlocked with the power failure detector X are switched to the primary power line 24 on the a contact side, and power from the commercial power supply is supplied to the power supply unit 10 (S1). Further, the second contacts X3a, X4a, and X5a linked to the power failure detector X are also closed, and the power from the relay board 14 is supplied to the lighting device 17, the cooling device 18, and the heating device 19 (S2).

  Even if the fourth contact X6b linked to the power failure detector X is opened, and an earthquake occurs, the seismic device EQ is activated and the third contact EQ1a is closed, the free sales terminal of the main control unit 12 is not short-circuited. The product is sold for a fee (S3). Further, the seventh contact X8b linked to the power failure detector X is opened, and the supply of power from the emergency power supply 11 to the sales indicator lamp 21 at the time of power failure is interrupted (S4). Moreover, the 6th contact X7a interlock | cooperated with the power failure detector X is closed, the reset terminal of the seismic device EQ is short-circuited, and the seismic device EQ is reset (S5).

  As described above, in a normal time when commercial power is supplied, the vending machine 1 operates with the commercial power and supplies power to the lighting device 17, the cooling device 18, and the heating device 19. And regardless of the presence or absence of an earthquake, products are sold for a fee. The emergency power supply 11 supplies power only to the seismic device EQ, and does not supply power to the sales indicator lamp 21 at the time of power failure.

  Next, as shown in FIG. 4, when an earthquake does not occur and the commercial power supply is out of power, the power failure detector X is not energized, and the coil constituting the power failure detector X is not excited (S10). Then, the first contacts X1c and X2c linked to the power failure detector X are switched to the emergency power line 25 on the b contact side, and the power from the emergency power supply 11 is supplied to the power supply unit 10 (S11). Further, the second contacts X3a, X4a, X5a linked to the power failure detector X are opened, and the power from the relay board 14 to the lighting device 17, the cooling device 18, and the heating device 19 is cut off (S12). Moreover, the 4th contact X6b linked with the power failure detector X is closed (S13). However, since the seismic device EQ is not operated here and the third contact point EQ1a is opened, the free sale terminal of the main control unit 12 is not short-circuited, and the product is sold for a fee. Further, the seventh contact X8b interlocked with the power failure detector X is closed, power is supplied from the emergency power supply 11 to the sales indicator lamp 21 at the time of power failure, and the sales indicator light 21 at the time of power failure is turned on (S14). Moreover, the seismic device EQ is not reset by opening the sixth contact X7a linked to the power failure detector X (S15).

  Further, since the seismic device EQ is not operated, the fifth contacts EQ2b and EQ3b are closed, and the manual switches S1a and S2a are disabled (S16). As a result, the power output from the emergency power supply 11 is always supplied to the power supply unit 10. When an earthquake does not occur, the power supply is often restored in a relatively short time even if the commercial power supply is interrupted, and there is little problem even if the manual switches S1a and S2a are disabled.

  As described above, in the state where the earthquake does not occur and the commercial power supply is interrupted, the emergency power supply 11 enables to pay for the product, and the power to the lighting device 17, the cooling device 18, and the heating device 19. Is cut off, so that consumption of the storage battery can be suppressed. In addition, by turning on the sales indicator lamp 21 at the time of a power failure, it is possible to notify the purchaser that the temperature of the product is not managed due to a power failure. Further, it is possible to prevent an act of intentionally pulling out the plug 23 and stealing a product.

  Next, as shown in FIG. 5, when an earthquake has occurred and the commercial power supply has failed, steps S10 to S15 are as described above. In addition, the third contact EQ1a linked to the seismic device EQ is closed (S17), the free sale terminal of the main control unit 12 is short-circuited, and the product is sold free of charge. Further, the fifth contacts EQ2b and EQ3b linked to the seismic device EQ are opened, and the manual switches S1a and S2a are activated (S18).

  At this time, while the manual switches S1a and S2a are not operated, the supply of power from the emergency power supply 11 to the power supply unit 10 is cut off, and the storage battery is not wasted. On the other hand, when the manual switches S1a and S2a are operated, electric power is supplied from the emergency power supply 11 to the power supply unit 10 only while the manual switches S1a and S2a are operated, and free merchandise can be sold (S19). When the commercial power supply is restored, the fourth contact X6b linked to the power failure detector X is opened and the sixth contact X7a is closed, and the seismic device EQ is reset to automatically shift from free sale to paid sale. (See FIG. 3).

  In this way, in the state where an earthquake has occurred and the commercial power supply has failed, it is expected that it will take time to restore the commercial power supply. Therefore, the manual switches S1a and S2a are enabled and the manual switches S1a and S2a are operated. By supplying power from the emergency power supply 11 to the power supply unit 10 only during the operation, the storage battery can be made to last longer. In general, since the vending machine is activated within a few seconds after being energized, there is no particular problem even if the manual switches S1a and S2a are energized.

  In addition, products are automatically sold free of charge in the event of an earthquake using the seismic device EQ, and the seismic device EQ and free sales are automatically reset when the commercial power supply is restored. However, there is no need to go to the vending machine 1 in a confused state after the earthquake.

Note that there are a plurality of wirings between the emergency power supply 11 and the sales indicator lamp 21 at the time of a power failure, and wirings on the load side from the power supply unit 10, but they are omitted in the drawing.

  Further, as shown in FIG. 7, the holding relay 22 includes a pair of power lines 27 supplied from the emergency power supply 11, the manual switch S1a, the first relay Y, the first timer TLR1, the transistor TR, and the second timer TLR2. Prepare.

  The manual switch S <b> 1 a is composed of an a contact that automatically returns, and is provided in a preliminary installation space of the currency sorting device 15 of the vending machine 1. When the commercial power supply is interrupted, the manual switch S1a is manually operated to start the operation of the holding relay 22 described later.

  The first relay Y is a relay that is self-held by operating the manual switch S1a. The first relay Y includes a self-holding contact Y1a, a first timer operation contact Y2a, and eighth contacts Y3a and Y4a for supplying power from the emergency power supply 11 to the power supply unit 10 when a commercial power supply fails. See).

  The first timer TLR1 includes a b contact for timed return, and the b contact is a first reset contact TLR1-1b of the first relay Y. The first timer TLR1 is energized by closing the first timer operation contact Y2a by the operation of the first relay Y. After a predetermined time has elapsed, the first reset contact TLR1-1b is opened, The self-holding is released.

  A voltage is applied to the base of the transistor TR in accordance with a currency enrollment signal that is output when money is inserted into the currency sorting device 15. Then, the transistor TR is turned on, the collector and the emitter are brought into conduction, and the second timer TLR2 is energized. Further, when the goods are sold and the money inserted into the money sorting device 15 is collected or the change is paid out, and the money put into the money sorting device 15 runs out, a currency enrollment signal is applied. The transistor TR is turned off, and the second timer TLR2 is not energized. If the currency enrollment signal is not a mode in which a voltage is always output, a known pulse detection circuit or the like can be provided separately to control the voltage applied to the base of the transistor TR.

  The second timer TLR2 has an a contact for instantaneous operation and timed return, and the a contact is a second reset contact TLR2-1a of the first relay Y. The second timer TLR2 is energized by turning on the transistor TR, the second reset contact TLR2-1a is instantaneously closed, and the first relay Y continues to be self-held. When the transistor TR is turned off, the second reset contact TLR2-1a is opened after a predetermined time has elapsed, and the self-holding of the first relay Y is released. Further, when the second timer TLR2 is formed of a coil, a diode can be connected in parallel with the second timer TLR2 in order to prevent the transistor TR from being damaged by the back electromotive force.

  Next, based on the function of each component described above, the operation of the vending machine 1 according to this embodiment will be described.

  The operation when the commercial power is supplied to the vending machine 1 of the present embodiment can be understood with reference to FIG.

  Next, the operation when an earthquake does not occur and the commercial power supply is interrupted will be described. As shown in FIG. 8, steps S10 to S12 and step S14 are the same as in the first embodiment. At this time, the first contacts X1c and X2c are switched to the emergency power supply line 25, but the power from the emergency power supply 11 is supplied to the power supply unit 10 only when the eighth contacts Y3a and Y4a are closed (S30). ).

  The operation of the eighth contacts Y3a and Y4a will be described with reference to FIGS. FIG. 9A is a diagram showing a case where the manual switch S1a is operated and the first timer TLR1 is energized, and FIG. 9B is a diagram in which money is inserted into the money sorting device 15 and the second timer TLR2 is energized. FIG.

  As shown in FIG. 9A, when the manual switch S1a is operated, the first relay Y is energized through the first reset contact TLR1-1b (S31), the eighth contacts Y3a, Y4a are closed, and the emergency power supply 11 is supplied to the power supply unit 10 (S30), the self-holding contact Y1a of the first relay Y is closed, and the first relay Y is self-held (S32). Further, the first timer operation contact Y2a is closed and the first timer TLR1 is energized (S33). Here, this state is maintained for a predetermined time, for example, 10 seconds, after which the first reset contact TLR1-1b is opened, and the first relay Y is reset (S34).

  As shown in FIG. 9B, when money is inserted into the money sorting device 15 in the state of step S33, a currency enrollment signal is input to the base of the transistor TR (S35). When the transistor TR is turned on, the second timer TLR2 is energized (S36), and the second reset contact TLR2-1a is closed (S37). Thereby, even if the 1st reset contact TLR1-1b opens (S34), the self-holding of the 1st relay Y is continued. Next, when the money inserted into the money sorting device 15 is no longer sold or returned, the money register signal is not output, the transistor TR is turned off, and the second timer TLR2 is not energized. . Then, after a predetermined time, for example, 1 second, the second reset contact TLR2-1a is opened, and the first relay Y is reset (S38).

  Thus, by providing the holding relay 22, when the manual switch S1a is operated at the time of a power failure, it is necessary to supply power from the emergency power supply 11 to the power supply unit 10 for a predetermined time and to continue operating the manual switch S1a. Disappear. In addition, since power is supplied from the emergency power supply 11 to the power supply unit 10 while money is being inserted into the money sorting device 15, the power of the vending machine is turned off and turned on while money is being inserted. It is possible to prevent the memory of money from disappearing.

  In the vending machine 1 of the present embodiment, only the third contact EQ1a linked to the seismic device EQ is connected to the free sales terminal of the main control unit 12, so that the commercial power supply is cut off when an earthquake occurs. Products are sold for free regardless of whether or not they are. Further, since the fifth contacts EQ2b and EQ3b (see FIG. 3) linked to the seismic device EQ are not provided, the manual switch S1a is always effective at the time of power failure of the commercial power supply. For this reason, for example, even in areas where typhoons frequently pass, such as in areas where there is a high possibility of power outages due to disasters other than earthquakes, it is possible to suppress storage battery consumption and sell products for a long time. . Since the sixth contact X7a (see FIG. 3) linked to the power failure detector X is not provided, when an earthquake occurs and the seismograph EQ is activated, the resetting is a manual operation.

As described above, according to the vending machine of the present invention and the accompanying power failure compensation device, since it is provided with a manual switch that performs power supply from the emergency power supply to the power supply unit only when necessary, the storage battery has a long life, It is possible to continue selling products for a long time in the event of a commercial power failure. In addition, a relay is a major component in realizing a power failure guarantee function for vending machines. For this reason, it is not necessary to provide a separate control unit, and the manufacturing cost can be reduced, and the operation pattern can be easily changed by rearranging the wiring of the relay by a technician on site.

The vending machine and the accompanying power failure compensation device according to each embodiment described above are examples of the present invention, and the configuration thereof can be changed as appropriate without departing from the spirit of the invention. For example, in the above-described embodiment, an electromagnetic relay is employed as the relay. However, a program relay, a solid state relay, or the like may be employed instead of the electromagnetic relay.
