Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to an automatic raw material supply and extraction device for a beverage vending machine.

[Prior art] Beverage vending machines or brewing machines dispense extraction materials such as powdered coffee, black tea, green tea, etc. sealed in packets in single-use quantities, and add boiling water to extract the ingredients. There is one described in Japanese Utility Model Publication No. 59-9353.

This is a coffee brewing machine equipped with a coffee extractor with a filter and a scraper for scraping coffee grounds remaining on the filter into the grounds discharge passage after each vending operation, at the outlet of the grounds discharge passage. A drain tray is placed on the side and is usually kept retreating to the side of the grounds discharge passage, and is pulled out to face the grounds discharge passage when cleaning the coffee extractor to receive cleaning waste water. This is a washing water recovery device for a fresh brew type coffee vending machine, characterized in that the wastewater recovery container is connected to a waste water recovery container separate from the grounds recovery container.

[Problems to be Solved by the Invention] However, this conventional technology has the first major problem, such as the need for a large amount of water for cleaning the filter, since coffee grounds adhere to the extractor, and the method is for cleaning the coffee grounds. There is a problem.

In addition, since the filter is installed inside the machine, unlike the case where perforations are made in individual containers, there is a risk that the raw material may become damp inside the powder raw material container or the odor from the large powder raw material container itself may adhere. There is a second problem.

There is also one shown in Japanese Utility Model Publication No. 39-16524.

In this product, coffee powder 3 is filled at regular intervals in two sheets of packing paper 2, 2, and a hot water injector 4 is designed to move up and down along a guide 5 at the top, and a cup 6 is placed at the bottom. It is a coffee vending machine with a

However, this conventional technology has major problems, such as the raw material for drinking coffee getting wet inside the beverage vending machine through the packing paper, and the coffee powder having an unpleasant odor due to foreign odors penetrating inside the beverage vending machine. .

Furthermore, as shown in Utility Model Publication No. 39-957,
a vessel having a filling opening in the brewer, a porous separator in circumferential contact with the inside of said vessel to form first and second compartments, and a breakable device for sealing the filling opening; the vessel is frangible and has a bottom wall and a side wall extending from the periphery of the bottom wall, and a rim extending in a plane from the top of the side wall; the first section is adapted to store dehydrated dairy products, said second compartment adapted to store ground coffee, characterized in that said closure extends beyond said filling opening and is connected to said rim. A brewer structure for the production of coffee beverages is proposed.

However, in this prior art, the brewer itself is a single and independent item, and moreover, a rosin is attached to the bottom of each individual brewer.

Therefore, this device requires a means for transporting the brewer to the extraction section one by one, and a means to pierce both the lid plate and the bottom plate of the brewer with a pouring nozzle and a drain nozzle, respectively. In particular, the first major problem is that the means for transporting each individual item of the brewer to the extraction section is extremely complex, requiring a large space and expensive manufacturing costs since the brewer itself is a single item.

In addition, since the pouring nozzle is pierced into the lid plate and the molten metal is poured under pressure to extract the molten metal, it is difficult to extract raw materials other than directly below the molten pouring piercing means 40, and the second problem is that the extraction efficiency is extremely poor. There is.

This invention eliminates all of the above-mentioned problems and is convenient for extracting the ingredients of coffee, black tea, or green tea in a short time and economically by adding hot water under pressure to raw materials such as regular coffee, black tea, or green tea. The purpose is to provide an extraction device.

[Means for Solving the Problems] The above object is to place a certain amount of raw materials into an airtight container consisting of continuous cup-shaped recesses, and to hermetically seal the opening of the airtight container with a sealing material. a first sprocket wheel for conveying a raw material airtight storage storage band having a perforation formed on the periphery of the stopper;
A second sprocket wheel that peels off the sealant from the airtight container, a winding drum that winds up the peeled sealant, and a large number of sprocket wheels on the bottom of the airtight container from which the sealant has been peeled off. A drilling machine equipped with a needle pin for making minute holes, an upper cylinder with a hot water pipe attached to the side and a piston inserted inside, and a lower cylinder with a discharge port that connects and separates from the bottom of the upper cylinder. This is achieved by configuring the drip mechanism.

[Function] The extraction device of the present invention uses the first and second sprocket wheels to convey a fixed amount of raw material airtight storage bands, and the second sprocket wheel and take-up drum to airtightly maintain one storage band. After tearing off the sealing material from the container and making a fine hole in the bottom of the airtight container with a needle pin to allow the raw material to pass through, the container is housed in a drip mechanism and the hot water sent through the hot water pipe is poured into the container. The raw material is extracted by force-feeding it from the upper cylinder to the lower cylinder with a piston, and when the extraction is finished, the container is taken out from the drip mechanism and prepared for dripping into the next container.

[Example] Fig. 1 shows raw material 1 such as roasted and medium-finely ground coffee beans, black tea, etc., placed in an airtight film made of cup-shaped depressions with a flat bottom at regular intervals in a belt-shaped resin film. Raw material container connection band 3 in which holding containers 2 are continuously formed
A certain amount of sealing material 4 made of the same material is heat-sealed to close the opening of each airtight container 2, and perforations 5 and lead portions 6 are placed on both side edges. This is the raw material airtight storage storage zone 7 provided.

The rigidity of the raw material container connecting band 3 in this raw material airtight storage storage band 7 is set to be stronger than the adhesive force between the sealing material 4 and the raw material container connecting band 3, so that when the sealing material 4 is pulled, the heat-sealed portion peels off. However, the sealing material 4 does not break, and the raw material container connection band 3 has a rigidity that will not bend under the above-mentioned force, and the heat-sealed portion is normally constructed to maintain complete airtightness. has been done.

The raw material airtight storage band 7 is stored in the beverage vending machine in a meandering manner as shown in FIG. 2a.

Next, the mechanism and drip operation for supplying the raw material 1 in the airtight container 2 from the raw material airtight storage zone 7 to the drip mechanism will be explained.

As shown in FIG. 2a, a dummy container 3a and a lead portion 6 are provided in advance at the tip of the raw material airtight storage storage band 7, and a pair of lead portions 6 are provided in front of the drip mechanism 8. The perforation 5 of this lead part 6 is locked to the sprocket of the sprocket wheel 9, and the tip of the sealing material 4 is inserted into the hole provided in the spool of the winding drum 10, and the raw material container is connected. The dummy container 3a of the band 3 is set in the drip mechanism 8 via the lower surface of the guide pin 10a.

When the customer inserts the fee and presses a selection button (not shown), the perforating machine 14, which is equipped with a heater 11 inside and a large number of fine needle pins 13 attached to the top surface, moves vertically by the operation of the cylinder 12. Then, a minute hole 2a is made in the flat bottom of the airtight container 2 to prevent the raw material 1 from leaking out.

When this hole drilling is completed, the hole punching machine 14 descends as shown in FIG. 2b, and the sprocket wheel 9
rotates to move the raw material container connecting band 3 to the right, and at the same time, the sealing material 4 heat-sealed thereon is strongly pulled and peeled off by the sprocket inserted into the perforation 5. The sealing material 4 to be paid out is wound around the winding drum 10, and since this raw material container connecting band 3 slides on the lower surface of the guide pin 10a and moves to the right, the above peeling operation closes the airtight container 2. As this movement progresses, the raw material container connection band 3 at the part where the sealing material 4 is peeled off allows the raw material 1 in the airtight container 2 to smoothly move into the upper and lower cylinders 15 without spilling. , 16.

After this, as shown in FIG. 2c, the lower cylinder 16 rises and the upper and lower cylinders 15 and 16 are brought into liquid-tight contact with each other via the O-ring, which corresponds to one cup from the hot water storage tank (not shown). An amount of hot water is poured into the upper cylinder 15 through the hot water pipe 17.

When the hot water is poured, the piston 18 in the upper cylinder 15 descends as shown in FIG. Accordingly, a preselected amount of sugar, cream, etc. is poured into a cup 21 taken out from an automatic cup feeding device (not shown).

When the dripping of one cup of coffee is completed, the piston 18 rises as shown in Fig. 2e, and the lower cylinder 16 descends, entering the standby state for the next customer. Regular coffee or black tea is extracted by the operation d.

[Effects of the Invention] As described above, the present invention adopts the means for solving the above problems, and in particular, creates a large number of fine holes 2a, 2a in the bottom of the airtight container 2 using a large number of needle pins 13. As a result, the beverage raw material 1 can be extracted with hot water and sold, so there is no need for separate parts such as filters or filters.
There is an effect.

Furthermore, with this invention, it is possible to sell a regular drink that is delicious and fragrant without causing the coffee raw materials to become damp inside the beverage vending machine, or the coffee powder having an unpleasant odor due to the penetration of foreign odors inside the beverage vending machine. The second effect is that the powder raw material does not scatter to other places.

Moreover, a certain amount of the raw material 1 is put into an airtight container 2 which is made up of continuous cup-shaped recesses, the opening of the container 2 is sealed with a sealing material 4, and the side edges of the container are perforated. The means for conveying the raw material airtight holding storage zone 7 formed with the raw material 5 is simple and requires only a small space, and since the molten metal is poured under pressure via the upper cylinder 15 and piston 18, the raw material can be extracted evenly, improving extraction efficiency. There is a third effect that is good.

Furthermore, the raw materials are automatically transported into the drip mechanism so that they can be dripped, and are then transported out of this mechanism, and the brewed sludge is discarded along with the container, so coffee, etc., is always brewed in a new container. It has the fourth and fifth effects, such as being hygienic because it can be washed away and being mechanically simple, resulting in low manufacturing costs.
