In addition, after extraction heat water valve 22 is closed, if the buyer presses the selector button that adds granulated sugar and coffee with cream beverage, the signal of then selling goods outputs to master control part 100 from the control part 101 of selling goods, and master control part 100 outputs to power on signal the power supply unit of metering motor 59A.Make metering motor 59A rotation based on this power on signal, the broken beans that are contained in measuring room 51 are released by piston 56D and are supplied to the cylinder body 32 of extractor 30 via rushing down groove 7D.Piston 56D with the forefront be reference position (metering initial point) retreat with in order to measure employed broken beans when selling goods next time with the corresponding amount of movement of volume (volume).From the pulse that metering scrambler 59B is exported, set by the rotation that stops to measure motor 59A when becoming the count value of regulation by counting for this amount of movement.

After broken beans are supplied with, drive cylinder cap motor 35 and make the cylinder unit D of extractor 30 tilt to extracting position.Cylinder cap 37 tilting action therewith synchronously inserts cylinder body 32, and optical sensor 36C becomes ' leading to '.Master control part 100 outputs to motor drive circuit 70 to power on signal based on ' leading to ' signal of optical sensor 36C, by driven plunger driving motor 33 piston 39 is risen, and compacting is contained in the broken beans in the cylinder body 32.The current value of the piston-driven motor 33 when detecting this compacting by current detection circuit 74 is braked piston-driven motor 33 when the corresponding current value of coffee beverage that detects and sell goods, and stops energising then.

The decrement of the broken beans that cause of compacting is set by the relation of the setting value of the electric current of amount that is stored in the storer 102 and the corresponding auxiliary material of the hobby buyer etc. based on the corresponding requirement of selling goods of other hobbies with the having or not of the having or not of the granularity of the kind (hot beverage, cold drink) of beverage, the roasting degree of frying in shallow oil of broken beans, broken beans, granulated sugar, cream, buyer and piston-driven motor 33 is read in master control part 100.

In addition, broken beans supply unit 7 usefulness electric coffee grinder 7B pulverize the coffee bean of being supplied with from beans storage container 7A, and the broken beans that use when next time selling goods supply to meter 5.

Broken beans are after compacting, and the heat water valve 23A that opens the pipe arrangement 15A that is connected to boiled water tank 10 supplies to mixing bowl 14 to boiling water, and the granulated sugar of being supplied with from sugar basin 11 is dissolved in the boiling water.Equally, the heat water valve 23B that opens pipe arrangement 15B supplies to mixing bowl 14 to boiling water, and the cream raw material of being supplied with from butter container 12A is dissolved in the boiling water.

Next, driving pump 60 and supply to cylinder body 32 at following boiling water that is heated to about 90～95 ℃ high temperature of 6～8 pressure by air pressure.The boiling water of this high temperature dissolving coffee component when by broken beans becomes coffee beverage, and 30A supplies to goblet 9 via the beverage supplying pipe.Flowmeter 19 outputs to master control part 100 with the corresponding flow signal of minable water yield through pipe arrangement 6A institute force feed during the extraction of coffee beverage.In goblet 9, supply with from the mixing bowl 14 of granulated sugar feed system and supply with the boiling water that has dissolved granulated sugar, and then supply with the boiling water that has dissolved cream from the mixing bowl 14 of milk oil system and mix with the coffee beverage that is extracted.

The extraction one of coffee beverage finishes, and just stops the driving of pump 60, and through opening heat water valve 24 behind the official hour (0.5 second), driven plunger driving motor 33 further rises piston 39.Based on the vertical motion of this piston 39 extracting the residue briquetting and extruding after the coffee beverage, close heat water valve 24, reverse driven plunger driving motor 33 piston 39 is descended, whereby the coffee extract solution among the pipe arrangement 30A that is trapped in retaining valve 21 downstreams is attracted in the cylinder body 32.The boiling water that is attracted is extracted residue and absorbs.

Extract the discarded of residue, make cylinder cap 37 from cylinder body 32 after separatings at driving cylinder cap motor 35, just changeing driven plunger driving motor 33 rises piston 39, make it to expose shifting the top onto on the extraction residue whereby, under this state, drive cylinder cap motor 35 cylinder unit D is rotated to stand up position from the top, top of cylinder body 32.One rotate by this, extract that residue is contacted with the scraper plate W that is located on the lower sides that rushes down groove 7D and from cylinder unit D to falling.After extracting the residue removal, reverse driven plunger driving motor 33 piston 39 is descended, finish to sell goods action whereby, become the waiting status of selling goods.

If adopt above-mentioned cup type automatic vendor, then the broken beans that supply to cylinder body 32 are compressed to the decrement of regulation based on the rising of piston 39, via pipe arrangement 6A the boiling water of the high pressure of regulation is supplied to these broken beans that compressed and extract coffee beverage, can make boiling water soak into broken beans equably whereby, can not produce extraction and promptly extract dense coffee beverage unevenly.In addition, after extraction, compress the extraction residue of broken beans, can coffee beverage not supplied to goblet 9 whereby with having omission based on the rising of piston 39, and so and because extract residue by the disposal raising in the discarded process of the solid shapeization residue of compression quilt.The conveyer that makes filter paper whereby or transport filter paper becomes unwanted and realizes the simplification that constitutes.In addition, based on be added in the decrement that the corresponding current value of load on the piston 39 detects broken beans, sensors such as load transducer needn't be set whereby and the compressive state that can correctly manage broken beans.

Though the manufacturing with regard to Hot Coffee is illustrated in an embodiment of the present invention, also can apply to sell the cup type automatic vendor of cold coffee.

As described above, if adopt cup type automatic vendor of the present invention, then, by piston solid shaped bodies is discharged from cylinder body, so can easily extract the waste treatment of residue with simple formation because extracting the back at coffee beverage compresses the broken beans of formation and become solid shaped bodies by piston.
