Embodiment 1

[0048] An unmanned vending machine, please refer to Figure 1 to Figure 9 .

[0049] like figure 1As shown, the unmanned vending machine provided by the embodiment of the present invention includes a cabinet 11, and the cabinet 11 is provided with multi-layer inventory pallets 111, and the space above each layer of inventory pallets 111 is divided into multiple cargo lanes 114 by vertical plates 112, The cargo lanes 114 are equivalent to a grid space, and each cargo lane 114 is provided with a cargo output mechanism, and the cargo output mechanism is a coil spring 113. In other embodiments, crawlers can also be used as the cargo output mechanism.

[0050] The working principle of the current unmanned vending machine is as follows: figure 2 As shown, a piece of goods 1131 is clamped in each pitch of the helical spring 113, and each goods on the same helical spring 113 is generally the commodity of the same type. At this time, the driving motor 1132 drives the coil spring 11...

Embodiment 2

[0072] A kind of unmanned vending machine, please refer to Figure 4 to Figure 18 .

[0073] On the basis of Embodiment 1, this embodiment further provides a detailed implementation of each circuit of the unmanned vending machine. Figure 10 to Figure 18 Among them, the DC power supply VCC and GND are the output terminals of the power module in the explosion-proof box of the unmanned vending machine of the present invention, and the DC power supply ib-VCC and ib-GND are the output terminals of the energy-limiting circuit.

[0074] like Figure 4 The five signal transmitters installed on the upper surface of the middle monitoring board are all light-emitting diodes, and the five signal receivers installed on the lower surface are all photoelectric receiving diodes.

[0075] like Figure 10 As shown, the first signal transmitter is a light-emitting diode D1, and the first control circuit corresponding to the first signal transmitter includes a transistor Q1 and a resistor R4, t...

Embodiment 3

[0097] An unmanned vending machine, see Figure 14 and Figure 19 . like Figure 19 As shown, in this embodiment, two Figure 14 The energy-limiting circuit in the circuit is connected in series and then used as an energy-limiting circuit to enhance the reliability of the energy-limiting circuit. This circuit is designed in accordance with the ib explosion-proof requirements. By designing the energy-limiting circuit, the explosion-proof requirements are met.

Abstract

The invention discloses a vending machine and a stock-out monitoring method thereof. The vending machine comprises a cabinet which is internally equipped with a plurality of layers of goods storage supporting plates. The space above each layer of goods storage supporting plate is divided into a plurality of goods channels. A signal transmitter and a signal receiver which are oppositely arranged upand down are arranged at the front end of each goods channel to monitor whether there are goods left or not in the forefront of the corresponding goods channel. If there is no goods at the foremost end of any goods channel, the signal receiver can receive a signal transmitted by the signal transmitter and can remind a tally man to supplement goods in time. The vending machine is further providedwith an energy limiting circuit and an explosion-proof box. Some power utilization modules are installed in the explosion-proof box, so that sparks generated by the circuits are prevented from being in contact with the outside. The energy limiting circuit can keep the working currents of electrical components on monitoring board cards stable and prevent the exposed electrical components on the monitoring board cards from generating sparks. Thus, the vending machine can be also used in places with inflammable and explosive substances such as gas stations in addition to common occasions.

Description

technical field [0001] The invention relates to the technical field of unmanned vending machines, in particular to an unmanned vending machine and a method for monitoring its shortage. Background technique [0002] Unmanned vending machines are common vending equipment in schools, restaurants, office building passages and other areas, which facilitates shopping for customers and reduces the sales cost of merchants. [0003] The unmanned vending machine has a system for counting the amount of goods on the goods and the amount of goods sold, which is convenient for merchants to know the remaining amount of goods on each cargo lane in the vending machine in real time. Goods statistics need manual assistance, and it is inevitable that there will be statistical errors in the management of goods. In this way, there will be cases where the goods are out of stock in the goods lane, but the statistical system shows that the goods are in stock, which may lead to consumers not being ab...
