The working principle of automatic vending machines

The working principle of automatic vending machines iron shell vending machine shell raw material is iron, the average person is kick. 。 。 Each roll of iron is 300 ~ 400 meters long and can do about 80 pieces of iron plate. Punching processing the curling iron with large roller pressure level off after the cut, after using all rivet hole punching machine, behind for fixed connection between the tin. Bending machine bending processing used to fold the edge, to make the shape of the box. Welding the first step in processing of the batch will use automatic welding manipulator, according to the prophase of automation procedures, good welding fixed path of a fixed position in turn. Need to increase the strength of key parts, such as will still use manual welding ( I to form a head. 。 。 ） Another also such welding assembly line part of the door, but always in the final assembly. Spray coating coating assembly line with automatic spray gun powder coating on the surface of the vending machine, also mentioned in the production of luggage factory in common automatic spraying manipulator, are good programming after spraying action, will have been ordered on homework ~ here is the use of static electric field between the gun and spraying surface, adsorption on the surface of the workpiece, the coating evenly. , of course, some of the detail of the part will still use manual spraying, workers are need to wear protection in place of the mask, lest the pneumoconiosis and poisoning. In the production of incandescent lamp incandescent light bulbs, also wrote the white also depend on electricity. When spraying the inside of the bulb silicon powder coating machine, can give a glass bulb at 30000 volts, the moment produced by the electrostatic let all clung to the inner surface of the glass powder, and because of the glass bulb burned before, powder not off on a stick. Is there a really amazing! Installation link link is mainly from the inside out in the best metal cabinet for installation: to install insulation material ( Polyurethane foam) , heating and refrigeration equipment installed ( Such as small air conditioning) And installation of the wind cooling fan to the room, and fitted with storage of goods shelves, cupboard door light, finally put below notes and COINS available recognizer. Recognition principle when it comes to the vending machine in the installation of COINS and paper money recognizer, coin, for example, is by identifying the shape, material, distinguish the categories of the coin. Different COINS on the diameter, thickness, material is different: first of all, the coin will by photoelectric sensor measuring the diameter of the coin size, for the first time to identify types of COINS; After rolling of the coin, passes through metal detection sensors, because different material have different metal phase delay of reflection of electromagnetic wave, so that it can be to further identify types of COINS twice ~ if you are unable to identify, COINS, would be the coin slot back, this persistence mechanism will be intercepted in COINS, and work under the pull rod or after a period of time will automatically return the COINS. While identify successful coin after distinguish between different denominations, rolled into different ways for storage. If it is paper money recognizer is according to the different characteristics of different denomination banknotes have to identify, such as paper, magnetic, width size, and so on, with a purple light, infrared and magnetic sensor identification signal parameters respectively, and then judge is not the money also will spit it out. Test after completion of assembly workers to check whether the shelves is strong, then invest the test items, the actual sales test to each purchase button. Finally the overall check whether there is any appearance damage on machine, reoccupy plastic package products, how can the factory ~ to buy success? When the instructions of the receive to drop some food sales, fixed in different food bar after a single servo motor will start: to convert electrical signal into mechanical signal on the motor, turn the pre-set number of turns, just make screens spring forward position of a food trip. Food in the process of falling light beam passes through the infrared sensor, this completes the drop at a time. If the system has not been detected food through infrared sensing beam, this could be the location of the food in the leak, the system will allow the servo motor to run, until the food drops. Stuck for vending machines as if happen more, like the image below, a lot of small lovely should be met. 。 。 I when I was in college, a dormitory building in the vending machine every day before closing is short selling drinks, such as the second day go to class and full, which is particularly curious fill in time! One day on a whim, sleep has been, etc. 。 。 Just found a little elder brother is in the still of the night after the replenishment in the middle of the night in the morning, feel what work is very hard, also more empathy, more respect and understanding, live so tired! 。 。
