Common faults and solutions of Guangdong vending machines

Common faults and solutions of Guangdong vending machines. In recent years, due to the advancement of production technology of domestic vending machine enterprises, the failure rate of vending machines has decreased significantly compared with the previous two years. However, it is impossible for large mechanical equipment such as vending machines to fail, so usually vending machines What are the reasons for the failure? Usually, the reasons for the failure of vending machines are mainly the following two categories: one is the failure caused by equipment problems, and the second is the problem caused by human causes. After the corresponding problem occurs, the device itself will generally show a corresponding prompt. According to different prompts, we can also solve it in different ways. Common failures 1 The green indicator of the vending machine's banknote device is displayed normally, but the banknotes cannot be received normally. Failure analysis: banknotes are not accepted because there are no coins for change, and the space for storing coins in the vending machine is limited. If you buy it on the same day There are too many people in the stuff, and the operator does not replenish coins in the vending machine in time, which will result in insufficient coins and no change. In order to avoid this situation, operators should replenish coins in time to ensure the normal operation of the machine. The second reason may be that the banknotes are too old to be recognized by the machine. The vending machine can only recognize more than 70% of the new banknotes. Therefore, it is recommended that consumers put in newer banknotes. The third reason is that the entrance of the banknote device is blocked, which may be artificially damaged, causing the machine identification system to malfunction, or that banknotes are stuck in the entrance. Another possible situation is that the machine has been used for a long time and some structural parts are aging, such as the rubber wheels of the banknote device or they are aging or falling off. It is recommended that the operator replace the rubber wheels. Common faults 2 The coin machine does not work normally, does not accept coins, or changes errors. Fault analysis: The coin machine fault is the same as the banknote machine fault. The coin machine recognition system is wrong. It may be dust accumulated on the recognizer port or the back end of the coin machine. The sensor malfunctions, causing the identification system to fail, or the coin refund system is faulty, and change cannot be found. It is recommended that operators regularly clean the related equipment of the vending machine and carefully check the operation of the gear of the coin refund mechanism. As for change errors, the reasons can be divided into two categories. One is that the operator did not add coins according to the standard requirements, or the coin tube was loosened and could not accept the coins correctly, or the coin refund box was not installed properly, causing the coins to fall into the machine, causing change failure; the second was the product The price is set incorrectly, so that the change is wrong. It is recommended that operators fill up coins correctly, install coin machine related equipment as required, and reset commodity prices. Common fault 3 The coin swallowing phenomenon occurs in the vending machine. After coin insertion, the machine does not display the number of coins inserted, or the machine normally displays the number of coins accepted, but the product is not sold normally. Fault analysis: swallow coins are the most popular vending machine operators Headaches are also the main cause of complaints from operators. In a similar situation, there are two main points of failure to consider, one is the coin machine, and the other is the delivery mechanism of the vending machine. If the coin machine malfunctions and the coin channel is blocked, it will be dealt with with the coin troubleshooting method. If there is a problem with the delivery mechanism of the vending machine, it is necessary to clean up the foreign objects in the cargo channel and troubleshoot the malfunctioning parts in time. Common fault 4: The display of the goods does not match the actual situation in the equipment. The cause of the fault is more complicated. The equipment micro switch failure, loosening, button failure and wiring problems may cause the problem to occur, so you should consider comprehensively when handling it, item by item Detection and exclusion. The problem can be eliminated by replacing or fixing the faulty parts and ensuring that the line is normal. Common fault 5 Display failure: The display is on strike, or the indicator light in the retail display turns red. Fault analysis: The display problem is relatively simple. Generally speaking, the main reason is the wiring problem and the hardware itself. Just check whether the line is connected in time, or check the color of the indicator light in the retail display to eliminate it. The circuit is intact, but the indicator light is red, and the display needs to be replaced. Some of the above are relatively common faults at present, for your reference, there are many common problems that we have not listed in actual operation.
