Description of the Related Art Conventionally, in automatic vending machines for selling cup beverages, as disclosed in, for example, Japanese Patent Application Laid-Open No. 4-354912 (A47J31 / 30), coffee (filter paper) is passed through a paper filter from a raw material such as coffee beans. The extract is extracted, mixed with other sugar or milk, and then poured into a cup for sale. In addition, due to the regulations of the Food Sanitation Law, it is currently impossible to store a predetermined amount of extracted beverage in advance and sell it one by one, so a method of extracting and selling one cup of coffee from the raw material for each sale Is taken.

[0003]

According to the extraction for each sale, although there is an advantage that fresh coffee can be extracted and sold every time, the extraction takes a long time, and therefore, as disclosed in the above-mentioned publication, it is conventionally required. It was necessary to shorten the extraction time by pressurizing with compressed air or the like.

Further, the paper filter after extraction is sent out by a delivery device with the raw material scraps on the upper surface and discarded in a waste container or the like. There are many risks of being scattered in the vending machine and becoming dirty, and cleaning the inside of the waste container is troublesome. By the way, if the Food Sanitation Law is revised, it is possible to extract and store a predetermined amount of beverage in advance even in this kind of vending machine and inject it into a cup one by one for each sale and sell it. Becomes According to such a method, it is not necessary to perform extraction between the selection of the product and the sale, so that the so-called natural flow drip method in which pressure is not applied by compressed air or the like can be used to sufficiently extract the beverage.

On the other hand, in that case, since a relatively large amount of beverage is extracted, the amount of the raw material residue is also large. Therefore, send out the paper filter after extraction,
The above-mentioned problem of fouling inside the vending machine when the raw material waste is discarded together with the paper filter becomes more serious. Therefore, in view of the conventional situation, it is an object of the present invention to provide a beverage extraction device capable of smoothly extracting a beverage from a raw material even by natural flow.

[0006] Another object of the present invention is to provide a beverage extraction device which can eliminate or reduce the problem of contamination due to raw material debris after extraction.

Next, the operation of the vending machine 1 having the above configuration will be described with reference to the flowcharts of FIGS. 3 and 16. 3 and 16 show a program of a control device (not shown) of the automatic vending machine 1, and the control device determines to collectively extract, for example, 26 cups of coffee in step S1 after the power is turned on. Next, in step S2, 26 cups of coffee (beverage) are extracted by discharging 26 cups of coffee powder and hot water.

Hereinafter, the extraction operation by the control device will be described with reference to FIGS. 4 to 14. In the initial state, the seal walls 35 and 36 are separated from each other above the extractor 6 as shown in FIG. 4, and the paper filter 7 passes through the roller 53 and goes under the upper side 57b of the guide member 57, so that the extractor 6 6
It is assumed that the roller is set so as to pass above and reach the roller 54. In this state, the control device controls the roller 5
The paper filters 7 are fed from the roll 7a by controlling the driving of the rollers 3 and 54. At this time, the roller 54 is the roller 5
It is stopped before 3, so that the paper filter 7 is loosened above the extractor 6 as in FIG.
In this case, the paper filter 7 may be loosened by making the rotation speed of the roller 54 slower than that of the roller 53.

Next, the drive of the drive motor 71 is controlled to rotate the guide member 57 as shown in FIG. 5 so that the loosened paper filter 7 extends along the upper surfaces of the opposing walls 33 and 34 of the extractor 6. Next, the control device controls the drive device 70 to lower the seal walls 35 and 36 as shown in FIG.
Both sides of the paper filter 7 are sandwiched by the elastic seal members on both sides of 34. As a result, an extraction space having a funnel-shaped cross section is formed in the area surrounded by the opposing walls 33 and 34 and the seal walls 35 and 36 of the extractor 6 as shown in FIG.

In this state, the control unit opens the shutter 51 of the cover 50 as shown in FIG.
By controlling the driving of the carry-out device 18 of the above, 26 cups of coffee powder (may be divided into several cups and extracted) and the opposing walls 33, 34.
It is dropped on the paper filter 7 on the upper surface. Next, as shown in FIG. 8, the shutter 51 is closed, the hot water supply solenoid valve 16 is opened, and hot water is poured from the hot water supply pipe 17 onto the coffee powder. At this time, as described above, the hot water supply pipe 17 is provided with a plurality of nozzles in the longitudinal direction above the extractor 6, so that the coffee powder is dripped almost entirely over the hot water. At this time, since the shutter 51 is closed, the steam rising from the extractor 6 toward the raw material unloading device 3 is blocked.

The hot water that has fallen on the coffee powder on the paper filter 7 penetrates into it, and coffee (liquid) is extracted from the coffee powder, but the extraction space in the extractor 6 is a cross section as described above. Since it has a funnel shape, the hot water spreads almost evenly over the entire coffee powder, and the coffee extracted from it flows down smoothly toward the extraction port 32. Therefore, coffee having a sufficient concentration can be extracted even by natural flow, and the extraction time can be relatively shortened. And 2
Six cups of coffee are filtered by the paper filter 7 and received in the beverage tank 27 through the extraction port 32.

When the predetermined extraction time elapses from the hot water supply by the hot water supply pipe 17, the control device controls the drive device 70 again,
The seal walls 35, 36 are raised to be separated from the extractor 6, and then the driving of the drive motor 73 is controlled to move the steppers 59, 59 as shown by arrows in FIG.
Push out a. At this time, the crosspiece 59a pulls the paper filter 7 on the side of the facing wall 33, and as shown in FIG.
Fold in 4 directions. Then, the stepper 59 is polymerized, and the needle joins both side edges of the paper filter 7 as shown in FIG. At this time, the roller 53 is free, and the stepper 58 is then returned to its original state.

Coffee (raw material) after extraction in this state
The debris is held in the paper filter 7 between the joints on both side edges. Then, the control device drives the rollers 53 and 54 to send out the paper filter 7, open the door 52 as shown in FIG. 12, and pull out the paper filter 7 holding the coffee grounds from the extractor 6. Next, FIG.
As described above, the drive motor 74 is controlled to lower the stepper 62 to join the upper edge of the paper filter 7 in the portion holding the coffee grounds with a needle. As a result, the coffee grounds are wrapped inside the paper filter 7. Further, the paper filter 7 is sent out, and eventually the waste container 2
Discarded in 4

Since the coffee (raw material) residue after the extraction is wrapped in the paper filter 7 and discarded as described above, the coffee residue may fall from the paper filter 7 even when the amount of coffee powder is large. Is prevented or suppressed. Therefore, the inconvenience that the inside of the vending machine 1 is contaminated due to scattering of dust is eliminated, and the dust container 24 can be easily cleaned.

After that, the control device drives the rollers 53 and 54 to let out the paper filter 7 from the roll 7a and loosen the paper filter 7 above the extractor 6 to obtain the state shown in FIG. When such extraction operation is completed,
In step S3, the control device uses the heat-retaining heater 29 to bring about
The coffee is kept warm at 63 ° C. in the storage device 8. Next, in step S4, the control device determines whether or not money has been input by the customer, coffee as a product has been selected, and a predetermined sales instruction has been issued, and if there is a sales instruction, the cup supply is performed. The cup 46 is discharged from the device to the selling port 44, and the discharge solenoid valve 31 is opened in step S5 to take out one cup of coffee stored in the beverage tank 27 into the mixer 9. Then, if necessary, the carry-out device 19 of the raw material carry-out device 4 is operated to discharge sugar and cream into the mixer 9, mix them with coffee with the stirring blades 42, and then pour them into the cup 46 from the beverage pipe 43. To do.

After the sale operation is completed, the control device proceeds to step S6 to determine whether the coffee in the beverage tank 27 of the storage device 8 is empty and is sold out. If the coffee is sold out, After proceeding to step S10 to store and calculate data relating to sales, step S1
Proceed to step 1 to execute the extraction and storage of the coffee again. At this time, in step S10, based on the sales situation until the coffee is sold out, for example, when the coffee is frequently sold, the amount of coffee to be extracted next time is increased, and conversely, when the coffee is not frequently sold, Reduce the amount of coffee to be extracted next time to reduce the amount of coffee that will be discarded as described later. Note that the calculation may be made by taking into consideration the season, the situation of people at the installation location, and the like by referring to the clock function.

Here, if coffee is stored in the beverage tank 27 of the storage device 8, the control device performs step S7.
Proceed to step 2 to determine whether it is within 2 hours from the beginning of extraction.
If it is within 2 hours, the process returns to step S4. On the other hand, if more than 2 hours have passed from the beginning, the process proceeds from step S7 to step S8, and the rinse work is executed.

This rinsing operation is shown in the flow chart of FIG. In step S11, the control device first puts the vending machine 1 into a sold-out state and then stops selling, and then in step S12, the discharge solenoid valve 31 is opened for 2 minutes to set the beverage tank 2
All the coffee in 7 is taken out, thrown into the waste container 47 via the mixer 9 and the beverage pipe 43. Next, in step S13, the seal walls 35 and 36 are lowered, the hot water supply solenoid valve 16 is opened to supply 60 cups of hot water into the extractor 6,
Perform empty extraction without coffee grounds. by this,
The extractor 6 and the sealing walls 35, 36 are cleaned. Also,
Hot water is also discharged from the rinse pipe 64, and the inner surface of the beverage tank 27 is washed together with the hot water from the extractor 6.

Next, in step S14, the discharge solenoid valve 31 is opened again for 3 minutes, and the hot water used for cleaning is discarded through the same route as described above. Then, in step S15, the roller 3
The paper filter 7 is sent out by 3, 34. When the rinsing operation is completed, the beverage tank 27 is returned to the standby state where the beverage tank 27 is set to + 63 ° C. in step S9, and thereafter, the process returns to step S1 to restart the extraction and storage of the coffee again.

Although the stepper 58, 62 is used as the filter paper joining device in the embodiment, the invention is not limited to this, and heat welding parts may be provided on both sides of the paper filter 7 to join them with a heat sealing machine. In addition, although the sales of coffee have been described in the examples, the present invention is not limited to this, and the present invention is also effective for providing sales of black tea, oolong tea, Japanese tea, and the like.

Further, although the beverage was extracted by gravity flow in the embodiment, compressed air may be supplied into the extractor 6 to further accelerate the extraction. Furthermore, it goes without saying that the present invention is not limited to the vending machine of the embodiment, but is also effective for coffee makers and the like used in coffee shops, offices and the like.
