Brief analysis of the failure of the vending machine and maintenance methods?

1. The vending machine is stuck; 　　 due to the use of spring spiral goods, the spring rotation will produce squeezing force on the product when the machine is shipped. The squeezing force has positive and oblique squeezing force. Under the action, the product is easy to fall over or even fall. This will cause the product to be stuck under the goods arrival (under the spring); under the action of the oblique squeezing force, the friction between the goods and the two side guards of the goods will be increased. When the friction is large, the goods will not be able to Ship normally.　　 Solution: First take out the stuck goods, and then enter the 'Fault' item on the vending machine management page and choose to clear the stuck goods fault. And in the future business, the placement of the goods will be changed accordingly. The main thing is that the size of the main product should be as consistent as possible with the size of the delivery, not too small or larger than the size of the delivery spring! 　　 2. Automatic The vending machine puts the change in, but the change does not enter the change device but is deposited in the money collection area; 　　 This problem is mostly due to a paper currency system error. Solution: Enter the system management page three minutes after shutting down, and then use a small stick to penetrate the reset button of the banknote device to reset (after inserting the small stick and pressing the reset button, you will see the light on the banknote device opening and then turning off again Let go if it’s on) Wait a few minutes and then turn it off and restart it again to basically solve the problem! 　　 Three, the vending machine is out of stock, and no change; 　　 The main reasons for this situation are as follows: 1. There is no change in the changer. There is change; 2. There is change in the change device, but the default amount of change in the system is zero; 3. The change device is stuck; 4. The paper currency device is too dusty. Solution: 1. Make up the change; 2. Enter the system management page to check if there is no record after the change was made last time (some vending machines need to manually enter the amount of change after making the change), if the amount is 0, please Modification; 3. Disassemble the banknote device to take out the jammed currency; 4. Disassemble the banknote device and use a brush to carefully and carefully clean up the dust or send it back to the manufacturer for cleaning. 4. The light on the banknote receptacle of the vending machine does not turn on or flickers, and the banknotes are not sucked into the machine at the same time; 　　 there are two possibilities for this type of problem: 1. There are foreign objects in the banknote No, 2. The iron cash box under the banknote device is not installed properly. Solution: Turn on the banknote device, remove the foreign objects, turn it off, and then turn it on again. Just turn off the power of the machine and reinstall the iron cash drawer! 　　 5. Scan the QR code and pay successfully without shipping. Solution: 　　 This is an unstable signal As a result, find out the signal line to pull the detection signal outside the cargo plane.
