Description

[Detailed description of the invention] [Industrial application field] This invention relates to an automatic opening device for containers containing raw materials, and more specifically, it extracts raw materials by opening the seal at the opening of an extraction container containing raw materials. The present invention relates to an automatic opening device for containers containing raw materials in beverage vending machines and the like.

[Prior art] As a beverage vending machine, for example,
As shown in Japanese Patent No. 69514, a basket having a dripping port formed at the bottom, a retractable hollow hose provided inside the basket and having its lower end connected to the dripping port, and an operating lever for expanding and contracting the hollow hose are provided. There is an extraction device.

Separately, as shown in Japanese Patent Application Laid-Open No. 57-132292, a perforated pipe with a pointed tip and a notched groove and a recessed portion near the tip is provided so that it can be raised and lowered, and the interior of the perforated pipe is Liquid injection in a vending machine, characterized in that an injection pipe is disposed in the vending machine, and a push-down mechanism is provided for pushing down and holding the perforation piece in response to the lifting and lowering process of the perforation pipe when the lid of the container is perforated. There is a device.

[Problem to be solved by the invention] Among the above-mentioned conventional techniques, the former, that is, the
What is shown in Publication No. 58-69514 is a so-called coffee server in which a person extracts drinking raw materials such as coffee with hot water, and in one extraction of raw materials in a basket, coffee for several people is dripped into the container. Since the liquid is dripped from the mouth and temporarily stored, and when a predetermined amount has been reached, the basket is removed and the extract in the container is drunk, the extraction of the raw materials is all done manually and is cumbersome.

In particular, with this conventional technology, it is necessary to manually remove the raw material residue inside the basket, which people dislike, and if the inside of the container is not thoroughly washed each time it is extracted, bacteria may grow or the remaining scent from the previous extraction may remain. There is a problem that it will be added to the next brewed beverage.

In addition, the latter of the above-mentioned conventional techniques, that is, the one shown in Japanese Patent Application Laid-Open No. 132292/1980, seals the opening at the upper edge of the container with a lid, and since it is not possible to polymerize a large number of containers, a large amount of storage space is required. There are some issues that need to be addressed.

Furthermore, an instant food such as instant noodles is stored in the container, a hole is made in the lid with a perforated pipe, and the instant food is heated and cooked with hot water injected from the injection pipe to serve for consumption.

That is, the bottom of the container is not perforated, so there is a major problem in that the raw material cannot be extracted.

In order to eliminate each of the above-mentioned problems, this invention makes it possible to open the non-porous thin film that is placed in the middle of the extraction container and sandwich the raw material in one motion without any manual intervention, and extracts the discharge of raw material waste. It is intended to be carried out together with the container.

[Means for Solving the Problems] The object of the above-mentioned invention is to provide an overfill material horizontally on the lower stepped surface portion of a cup-shaped container body having an upper stepped surface portion and a lower stepped surface portion, and to A raw material-containing extraction container in which the raw material is placed in the upper part and the upper surface and lower opening of the upper stage portion are respectively sealed with non-porous thin films; a base plate on which the raw material-containing extraction container is placed; A container pushing member for pushing the extraction container containing the raw material in the direction of the extraction section, and an opening mechanism having a blade at the tip of a pair of lifting rods provided above and below with the base plate sandwiched therebetween, respectively. The blades are pierced through the non-porous membranes provided at the upper and lower openings of the extraction container containing the raw materials by lowering and raising the elevating rod, respectively, and the extraction container is pushed in the direction of the extraction section by the container pushing member, thereby removing the non-porous material. This can be achieved by making an incision in the membrane and providing a control section for returning the lifting rod and the pushing member after the incision.

[Function] An overfill is placed flat on the lower stepped surface of a cup-shaped container body having an upper stepped surface and a lower stepped surface, and raw materials are put into the upper part of the overfilled material so that the upper and lower surfaces of the upper stepped surface are An extraction container containing the raw material whose openings are each sealed with an impermeable thin film is placed on a base plate, and the extraction container containing the raw material is temporarily held on the base plate by a container pushing member. An unsealing mechanism having a blade at the tip of a pair of lifting rods disposed above and below the container can cut open the non-permeable thin film provided at the upper and lower openings of the extraction container containing the raw material.

[Example] The automatic opening device for an extraction container containing raw materials of this invention is constructed as shown in FIG. 1a.

First, an opening 13 is made in the bottom plate 12 of the tapered cup-shaped container body 11.
A non-air permeable thin film member 14 such as aluminum foil is attached to cover the container body 11, and a cover member 16 is attached to the lower stepped surface portion 15 of the container body 11, and the raw material 17, which is medium-fine ground coffee beans, is placed on top of this. The amount necessary for extraction for one person is filled, and a non-porous thin film member 19 similar to that described above is attached to the upper stepped surface section 18 provided at a position where other extraction containers can be stacked from the upper open end to seal the raw material. The containing extraction containers 1 are stacked as shown in FIG. 4 and placed in a raw material stocker (not shown), and are automatically taken out from the stocker onto the base plate 2 by a customer's selection operation.

The mechanism for opening this extraction container containing raw materials is the first
As shown in FIG. A push hook 33 having a curved surface so as to be able to abut a part of the side surface of the main body 11
and a container body 11.
Plunger 41a provided at a position higher than the height of
and a plunger 41b and lifting rods 42a, 42b arranged so as to face each other below the base plate 2, and single-edged blades 43a, 43b like chisels at the ends of the lifting rods 42a, 42b, as shown in FIG. It is composed of a plurality of unsealing mechanisms 4a and 4b to which are attached, and a control section 5 that controls both mechanisms by the following operation sequence using a microcomputer.

In other words, as shown in FIG. 5, this control section 5 connects a piston 32 provided in the fluid cylinder 31 of the pushing mechanism 3 to a plurality of output terminals of a microcomputer CPU having a plurality of product selection switches S1, S2 to Sn at its input ends. Relay RY1 of a fluid control solenoid valve for driving the plungers 41a, 41
Relays RY2 and RY3 are provided to excite the microcomputer CPU in a predetermined sequence according to the control flowchart and time chart of the microcomputer CPU shown in FIGS. 6 and 7, respectively. It is configured to

The opening mechanism of this invention is constructed as described above.Next, the extraction of raw materials from a container containing raw materials using this mechanism and the processing after extraction will be described.

As shown in FIG. 1a, a raw material extraction container 1 containing a raw material selected by the customer (Blue Mountain, Kilimanjiero, etc.) is taken out onto a base plate 2 from a raw material extraction container storage section (not shown). At this point, the container pushing member 3 and the unsealing mechanisms 4a, 4b
None of them are working.

Next, as shown in FIG. 1b, when the plungers 41a and 41b of the unsealing mechanism are energized based on the flow chart and time chart of FIGS. 6 and 7, the elevating rods 42a and 42b protrude as shown by the arrows.
The blade 43a connects the impermeable thin film member 19 to the blade 43a.
b pierce through the non-air permeable thin film member 14 through the opening 21 made in the base plate 2.

Further, as shown in FIG. 1c, FIG. 6, and FIG. 7, fluid pressure is applied to the cylinder 31 of the container pushing member 3, and when the rod 32 protrudes in the direction of the arrow, the extraction container 1 containing the raw material is placed on the stand. The plate 2 is pushed to the right by a certain amount, and with this pushing action, the impermeable thin film members 14 and 19 are forcibly torn off with blades 43a and 43b, forming a rectangular opening 14a as shown in FIG. ,1
9a forms.

Thereafter, as shown in FIG. 1d and FIG. 7, when the power to the plungers 41a, 41b is cut off, the lifting rods 42a, 42b move back as shown by the arrows, and the blades 43a, 43b are moved to the non-porous thin film member 14. , 19, the cylinder 31 operates again and pushes the container 1 containing the raw material to the extraction section 6.

When the extraction container 1 containing raw materials stops on the mesh plate 61 communicating with the base plate of the extraction part 6, hot water is poured from the hot water supply nozzle 62 through the opening 19a into the extraction container together with sugar (syrup) and milk from other supply mechanisms. A certain amount of the liquid extracted from the raw material 17 is poured into the opening 14a,
It is poured through the mesh plate 61 and the funnel 63 into the paper cup 7 which is supplied below the funnel 63 by a cup supply mechanism (not shown).

When the extraction operation is completely completed, the extraction container 1 containing the raw material with the extracted raw material residue remaining is placed in Figure 1 e and Figure 7.
As shown in the figure, in the third operation of the container pushing member 3, the container is pushed down from the extraction section 6 into the container of the container recovery section 8 and is recovered.

After this, each mechanical part returns to the standby state shown in FIGS. 1a and 6 (but in this case without the brewing vessel) for the next customer.

[Effects of the invention] As described above, this invention adopts a means to solve the above problems, so containers can be stacked, saving storage space and protecting raw materials from moisture. In addition, the upper and lower non-air permeable thin film members 14, 19
Since relatively large holes necessary for extraction can be opened automatically, raw materials such as regular coffee can always be extracted with hot water without spoiling the flavor, and the extraction container with raw material remains can be placed in the collection container as is. Since the raw materials can be recovered in a new extraction container at all times, it is hygienic, and the residual aroma of the previously sold beverage is not added to the next sold beverage, and it also has effects such as reducing operation costs.
