Description
Technical field
The present invention relates to beer selling machine, specifically, relate to a kind of beer selling machine with function of measuring.
Background technology
The beer selling machine that is used for the beer on tap retail in the market, need be by the shop-assistant on duty and operation, and along with the development of society, retailer and consumer thirst for having a kind of beer selling machine that can sell beer automatically, on the one hand the retailer only need be nursed, need not staff on duty and operation, but labor savings and operating cost, make the consumer can independently buy beer as required on the other hand, needn't handle by the shop-assistant, convenient more, therefore existing beer selling machine can not satisfy retailer and consumer demand.
In addition, barrelled beer is in transportation, and the carbon dioxide gas in the beer is known from experience volatilization; And beer selling machine in the market mostly is the open type beer selling machine greatly, beer all is exposed in the space in whole sales process, carbon dioxide in the beer volatilizees in a large number, so that carbon dioxide content deficiency in the beer on tap of selling, and causes the mouthfeel of beer not good.
Summary of the invention
Technical matters to be solved by this invention provides the beer selling machine with function of measuring that a kind of operator of need not is on duty and operate; And further provide a kind of good beer selling machine of beer on tap mouthfeel that has function of measuring and can make sale.The technical scheme that adopts is as follows:
A kind of beer selling machine, comprise beer feedway and wine outlet, it is characterized in that: be provided with electric-controlled switch and flowmeter measuring device between described beer feedway and the wine outlet, beer feedway, electric-controlled switch, flowmeter measuring device and wine outlet are connected by the liquid pipe successively; Described beer selling machine also comprises the charge control device, the charge control device comprises coin pick-up unit and/or IC-card read write line, microprocessor, coin pick-up unit and/or IC-card read write line are connected with microprocessor, the output terminal of microprocessor connects electric-controlled switch, and the flowmeter measuring device is connected with the input end of microprocessor.
The coin pick-up unit detects the coin that receives and gives microprocessor with corresponding information conveyance, confirm coin be the value of money of genuine note and input after (by the true and false and the value of money of coin pick-up unit or microprocessor judges coin), microprocessor carries out computing according to the value of money of input, obtain and the proportional beer selling amount of value of money, and export a control signal simultaneously and give electric-controlled switch, make the electric-controlled switch conducting; After perhaps the IC-card read write line is confirmed purchasing capacity for liquor or purchasing the tips volume of IC-card and input, give microprocessor with corresponding information conveyance, and on IC-card, write down simultaneously and purchase capacity for liquor or purchase the tips volume, microprocessor carries out computing and obtains corresponding beer selling amount subsequently, and export a control signal simultaneously and give electric-controlled switch, make the electric-controlled switch conducting.Beer in the beer feedway is through electric-controlled switch, flowmeter measuring device then, and flows out from wine outlet, and the flowmeter measuring device measures the flow of beer simultaneously, and will measure numerical value and flow to microprocessor, by the discharge of microprocessor calculating beer; When the beer discharge of microprocessor calculating equals the beer selling amount, microprocessor sends a control signal and gives electric-controlled switch, electric-controlled switch is closed, wine outlet no longer flows out beer, wine outlet flowed out quantity and dropped into the proportional beer of value of money this moment, or with the purchasing capacity for liquor or purchase the proportional beer of tips volume of IC-card read write line input, thereby finish a beer selling process.
Usually beer selling machine receives coin, in this case, above-mentioned charge control device comprises coin pick-up unit, microprocessor and coin passage, the coin pick-up unit comprises coin diameter pick-up unit and coin material pick-up unit, and the coin diameter pick-up unit all is connected with microprocessor with the coin material pick-up unit; The detecting sensor of the detecting sensor of coin diameter pick-up unit and coin material pick-up unit is located on the coin passage successively.
Preferred above-mentioned coin diameter pick-up unit adopts optic coupling element as detecting sensor, optic coupling element is made up of the phototriode of a plurality of emitting diodes and similar number, emitting diode is arranged at the both sides of coin passage respectively with phototriode and aligns mutually, output end of microprocessor connects emitting diode by driving circuit, and the output terminal of phototriode connects the input end of microprocessor.More preferably emitting diode and phototriode are arranged along the direction perpendicular to coin passage respectively.Under the situation that does not have coin to pass through, all phototriodes all can receive the light that emitting diode sends; When coin passed through, coin covered the light that part or all of emitting diode sends, and corresponding phototriode does not receive light, and its output level (high level/low level) also changes, and microprocessor receives corresponding information.Coin diameter is big more, the light that can cover is also just many more, and the phototriode that changes output level is also just many more, so microprocessor is according to the situation of high level/low level in the information that receives (promptly 1/0), can judge the size of coin diameter, tentatively judge value of money.
