BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pressure vessel sealing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pressure vessel sealing apparatus, and more particularly, to a pressure vessel sealing apparatus that includes a pressure vessel having a high pressure, The present invention relates to a pressure vessel sealing apparatus for a ramen vending machine capable of preventing leakage of pressure.

Generally, ramen is classified into a cup noodle which is prepared by pouring hot water into a ramen noodle which has already been cooked, a bag noodle which is prepared by adding soup into ramen noodles and boiling water, and adding various seasonings according to taste.

Among such ramen, if the cup noodle is prepared only hot water, it can be easily cooked and consumed in a short time in the outdoor, so that a vending machine capable of automatically selling cup noodles could be developed. In other words, in the case of cup noodles, it is possible to eat only boiling water before processing, so it can be eaten in 2 to 4 minutes by pouring hot water. It could be easily developed as a vending machine.

However, in such a cup, the automatic vending machine is a semi-automatic method in which the user must manually perform the process of injecting the hot water into the container, which is accompanied by inconvenience and inconvenience, and pouring hot water for taste or texture, There is a problem that can not be overcome much if you eat boiled bag. In other words, the cooking method of cup noodles has a disadvantage in that it is remarkably different from the ramen noodles in which the taste and texture of noodles are boiled and consumed in the way that they are eaten by hot water, unlike the case of a bag that is boiled for eating at home.

In recent years, a ramen vending machine capable of providing the same texture as instant noodles, which are automatically cooked and boiled, is being developed.

Korean Utility Model Registration No. 20-0307102 discloses that "a basket coupled by a support to a chain that is moved by the operation of a transfer motor allows the container to be supplied from a container delivery device while being linearly reciprocating, The rack is engaged with the rack by the rotation of the pinion connected to the elevating motor, and the lid is lowered while the rack is linearly moved, And the water and the soup are supplied to the inside of the container by an amount set by the water supply pipe and the soup supply pipe connected to the lid body, and the heater coupled to the lid body generates heat while being supplied with electric power, After boiling the soup and the water for a predetermined time, the lid is lifted up by the operation of the lift- The upper part of the container is opened and the transporting motor is operated again so that the container and the basket containing the surface can be transported in the direction of the outlet of the body so that the user can take out the automatically boiled ramen, Providing a vending machine ".

This has the problem that it is not possible to significantly reduce the time it takes to fully ramen under atmospheric pressure, although it is possible to boil the water with a heater attached to the lid that covers the container. In case of ramen, cooked at 100 ℃ for a certain time under atmospheric pressure. However, when the bag is boiled for more than 3 minutes, it begins to ripen from the surface of the noodles and slowly rises to the inside of the noodles, so that when the inside is fully cooked, the surface of the noodles starts to spread out.

According to Korean Patent Laid-Open Publication No. 10-2014-0126515, there is provided a ramie taking-out unit for taking out a container containing a ramie loaded in a ramie loading unit one by one, A ramp transfer unit for transferring the container containing the ramen taken out from the ramie taking-out unit to the cooking position, a soup supply unit for supplying the soup into the container in a state where the container containing the ramen is housed in the cooking position, A water supply unit for supplying a proper amount of water to the container containing the ram noodle, a cooking unit including a cooker for cooking the ram noodle into which the water and the soup are introduced, a take-out unit for taking out the user's cooked ram noodle, The apparatus state of the vending machine and the user selection contents by the input unit are displayed in the table A display unit that; and if the if constituted by a control unit which controls the operation or status of the unit, including all the mounting unit provides a vending machine "and has an open bar. This is not a cup noodle, but it offers automatic noodle boiling directly, and the customer has the advantage of choosing a recipe, but it still does not solve the problem that it takes a long time to cook and must be provided within a short time after the order required by the vending machine.

On the other hand, in Korean Patent Laid-open Patent Publication No. 10-2007-0097935 (Oct. 5, 2007), "Special Pressure Pot for Ramen" and Korean Patent No. 10-1325785 (Oct. 30, 2013) "Vacuumable Airtight Pot with Pressure- A structure capable of being cooked using a pressure vessel has been disclosed. However, since the pressure is basically supplied only by the steam pressure generated during cooking, the time required for boiling the ramen is not greatly reduced. This is because, when the pressure vessel is initially heated, the steam pressure is not formed, so it is cooked in a general cooking mode and it is possible to cook at a high pressure within a certain time. Therefore, the cooking time is difficult to shorten and the texture of cooked noodles is limited.

When the ram noodle is cooked using such a pressure vessel in which the high pressure is applied, the leakage of the pressure becomes a serious problem. Therefore, there is a need to develop a structure for sealing the pressure vessel and for releasing the pressure upon completion of cooking in order to prevent pressure leakage.

Korean Patent Laid-Open Publication No. 10-1999-025752 (April 6, 1999) Korea Registered Utility Model 20-0187332 (Apr. 17, 2000) "Ramen Feeding Device for Vending Machine" Korea Registered Utility Model 20-0307102 (Feb.28, 2003) "Ramen Vending Machine" Korean Patent Laid-Open No. 10-2014-0126515 (Oct. 31, 201) "Ramen Vending Machine and Control Method Thereof" Korean Patent Laid-open Publication No. 10-2007-0097935 (Oct. 5, 2007) " Korean Patent No. 10-1325785 (Oct. 30, 2013) "Vacuumable airtight pot with lid for easy pressure change"

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a pressure vessel of a ramen vending machine having a structure and mechanism capable of completely sealing a pressure vessel, Thereby providing a sealing device.

According to another aspect of the present invention, there is provided an apparatus for sealing a pressure vessel provided in a ramen vending machine and cooking a ramen at a high pressure, the apparatus comprising: Vessel; An air hole provided above the pressure vessel for supplying hot water and compressed air, and a steam discharge hole for discharging high-pressure steam; And a switching cylinder for moving the pressure lid up and down to open and close the pressure vessel, wherein a locking cylinder for stopping the elevating and lowering of the opening and closing cylinder may be provided at a lower portion of the opening and closing cylinder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For a better understanding of the present invention, the description with reference to the drawings is not intended to limit the scope of the present invention. In the following description, a detailed description of related arts will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

First, a pressure vessel sealing device of a ramen vending machine according to the present invention is installed inside a ramen vending machine and is capable of cooking a ramen surface in a pressure vessel in a short time. To understand this, the structure of a ramen vending machine is briefly described with reference to Fig. I will explain.

1 is a structural view showing the overall structure of a ramen vending machine.

A ramp feeder 100 is provided at an upper portion of the ramp feeder 100 to push the uppermost ramp face to one side to supply the ramp feeder 100 A high pressure hot water supply device 300 installed on the ramp transfer device 200 for supplying hot water and high pressure air to the pressure vessel sealing device 400, The pressure vessel sealing device 400, the pressure vessel sealing device 400, and the pressure vessel sealing device 400 according to the present invention, which are installed on one side of the ramp supply device 100 and can transfer the ramp surface from the ramp transfer device, A ramen container dispenser 500 for supplying the container C to the lower side of the ramp container C and a ramen dispenser 600 for delivering and delivering the ram noodle cooked in the pressure container closure device 400 to the container C So Lure off, if the purchaser entered an order from outside the automatic rapid cooking Ramen in the works to be provided to the purchaser.

2 to 5 together with an understanding of the overall structure of the above-described ram noodle machine will be described with reference to a pressure vessel sealing device of a ramen vending machine according to an embodiment of the present invention. FIG. 2 is a structural view showing the structure of a pressure vessel sealing device of a ramen vending machine according to an embodiment of the present invention, FIG. 3 is an internal structural view of the locking cylinder of the present invention shown in FIG. 2, Sectional view of the container and the pressure lid, and Fig. 5 is a plan view showing the structure of the pressure lid of the present invention.

2, the pressure vessel sealing device may include a pressure vessel 410, a pressure lid 420, and an opening / closing cylinder 430, and may further include a locking cylinder 440 .

First, the pressure vessel 410 is configured to be cooked when heated by the heater 411 in a state where the ramp, hot water, and compressed air are supplied and accommodated.

The heater 411 may be embedded or embedded in the pressure vessel 410.

Therefore, it may be embedded in the side wall or bottom of the pressure vessel 410, but is preferably buried in the floor. The heater 411 may be an electric heating wire or a heating plate.

The pressure vessel 410 may be made of a light metal material that is resistant to high pressure and has high thermal conductivity, and aluminum can be used. It can also be coated with ceramics on the inner surface.

As shown in the figure, the pressure vessel 410 has a first inclined portion 412 formed on the inner circumferential surface of the inlet and a second inclined portion 413 formed on the lower side thereof. The first inclined portion 412, A step portion 414 is formed between the second inclined portions 413, so that the longitudinal section can be formed as a trapezoid.

Here, the first inclined portion 412 is in contact with the rim of the pressure lid 420 and may be inclined downward. The inclination angle of the first inclined portion 412 may be in a range of 45 ° to 85 °.

That is, when the angle is smaller than 45 degrees, the inclination of the first inclined portion 412 becomes too gentle, and even if the pressure lid is closed, a high pressure is applied to the inside of the container. If the angle is larger than 85 degrees, the inclination of the first inclined portion 412 becomes too sharp and almost vertical, so that the sealing effect is excellent but the pressure lid 420 is difficult to open.

The second inclined portion 413 extends downward from the first inclined portion 412 and is inclined. The inclination angle of the second inclined portion 413 may be in a range of 60 ° to 80 °.

That is, the amount of hot water to be cooked in one ramen is about 500 cc, and ramen is fully immersed in hot water and must be cooked to be cooked evenly.

When the inclination angle of the second inclined portion 413 is smaller than 60 °, the surface of the pressure vessel 410 is not fully immersed if the water level of a predetermined amount is lowered. When the inclination angle of the second inclined portion 413 is greater than 80 °, It is possible to take a ram noodle to be put in.

For reference, in the present invention, the optimal inclination angle of the first inclined portion 412 is 78 ° and the optimal inclination angle of the second inclined portion 413 is 72 ° as a result of various experiments and trial and error.

A step portion 414 is formed between the first inclined portion 412 and the second inclined portion 413 so that the pressure lid 420 is seated while being seated.

On the other hand, a cooking space 415 having a constant inner diameter can be formed on the lower side of the second inclined portion 413. The cross-sectional area of the cooking space 415 has a minimum area so that one ramen can be accommodated.

In addition, a predetermined amount of hot water to be cooked in the cooking space 415, that is, a portion of the ramp that is raised from the bottom of the pressure vessel 410 to the lower end of the second inclined portion 413 occupies the cooking space 415 It can be equal to the water level.

Next, the pressure lid 420 will be described with reference to FIG. 5 is a plan view showing the structure of the pressure lid of the present invention.

The pressure lid 420 can be opened and closed while being lifted and lowered from the pressure vessel 410 to seal the pressure vessel 410 while being cooked at a high pressure.

An air hole 421 for supplying hot water and compressed air at the same time is formed on the upper surface of the pressure lid 420. The air hole 421 is connected to the high-pressure hot water supply device 300 installed in the ramp vending machine and is provided with a check valve (not shown) so that hot water and compressed air can be freely injected. The steam can be blocked from leaking.

A steam discharge hole 422 is formed on the upper surface of the pressure lid 420 to discharge high-pressure steam. The steam discharge hole 422 is a passage for discharging the high-pressure steam inside the pressure vessel to the outside when cooking is completed, if it is at a high pressure.

Therefore, the steam discharging hole 422 may be closed when cooking is performed if a separate on-off valve (not shown) is provided, and may be controlled to be opened for discharging steam upon completion of cooking.

At this time, one or more steam discharge holes 422 may be provided.

Namely, the vending machine of ramen can not be consumed much time to discharge the steam because it needs to cook the ramen within a short time. However, if the inner diameter of the steam discharge hole 422 is excessively increased to quickly discharge the steam in a short period of time, a large noise may be generated when the opening / closing valve is opened, and the cooked ramen inside the pressure vessel 410 may be scattered .

Accordingly, in the present invention, a plurality of the vapor discharge holes 422 may be opened to open the steam discharge holes 422 step by step.

For this purpose, three to four discharge holes, such as a first steam discharge hole 422a, a second steam discharge hole 422b, a third steam discharge hole 422, and a fourth steam discharge hole 422, , This problem is solved.

Further, an auxiliary vapor discharge hole 422 having a diameter larger than that of the steam discharge hole 422 may be additionally formed. That is, when the pressure inside the pressure vessel 410 is gradually decreased through the relatively small-diameter steam discharge hole 422 and the auxiliary vapor discharge hole 422 having a relatively large diameter is opened, the steam is rapidly discharged It is possible to obtain an effect of discharging.

The pressure lid 420 may further include a gauge mounting hole 424 through which a gauge for measuring a pressure inside the pressure vessel 410 can be installed.

The lower edge of the pressure lid 420 may have a shape corresponding to the inlet side of the pressure vessel 410.

That is, a sealing slope 425 is formed on the lower edge of the pressure lid 420 so as to be in close contact with the first slope 412, and the sealing slope 425 is provided with an O- The same sealing member 428 may be further provided.

At this time, the closed inclined portion 425 is also formed to correspond to the inclination angle of the first inclined portion 412.

The pressure lid 420 is made of a material which can withstand high pressure like the pressure vessel 410.

Preferably, a pushing member 426 is provided on the lower surface of the pressure lid 420 to press the ramp in the pressure vessel 410.

The pushing member 426 functions to press the ramen floating in the hot water so as to be immersed in the hot water.

The pushing member 426 may have a width and a cross-section so as to press the ramp surface, and may have a flat plate shape, but have a constant thickness. This is to ensure that the noodle is loosened while being cooked so that it does not come into contact with the pushing member 426.

Therefore, the pushing member 426 is not completely immersed in water when the ramn surface is pressed, but is partially locked.

The support member 427 can be used to fix the pushing member 426 to the pressure lid 420. [

Next, the opening / closing cylinder 430 for moving the pressure lid 420 up and down will be described.

The opening and closing cylinder 430 is installed vertically above the pressure lid 420 and the pressure lid 420 is coupled to the rod 431. One or more fastening tabs 420a may be formed on the pressure lid for engagement.

At this time, the opening and closing cylinder 430 may be driven by hydraulic pressure or air pressure.

A piston 431 is provided in the opening and closing cylinder 430 and an inlet 441a is formed at an upper end and a lower end for pneumatic or hydraulic pressure injection. The piston 431 and the rod 432 are closed when the piston 431 and the rod 432 are supplied to the upper injection port 441a and the pressure lid 420 is closed. And the pressure lid 420 is opened.

Also, the pressure lid 420 may be directly coupled to the rod 431, but a separate insulating member 433 may be interposed between the lower rod 431 and the pressure lid 420.

The insulating member 433 may be in the form of a block, and may be made of a synthetic resin material such as Teflon, which has high strength and can block heat transfer. This prevents heat from being transferred from the pressure cap 420 to the opening and closing cylinder 430.

Accordingly, as the rod 431 of the opening / closing cylinder 430 moves up and down, the pressure lid 420 can close or open the pressure vessel 410.

Importantly, the opening and closing cylinder 430 should use a cylinder having a sufficient capacity so that the pressure lid 420 is not pushed open at a high pressure in the pressure vessel during cooking. A cylinder capable of calculating the reaction force due to the pressure in the pressure vessel and withstanding the load can be used.

Even if the pressure vessel 410 is sealed by the pressure cap 420 by driving the opening and closing cylinder 430, if a high pressure is applied to the inside of the pressure vessel 410, Can become too large and crowded. This causes the pressure lid 420 to be partially opened, excessive pressure is leaked, or excessive power is consumed to increase the driving force of the opening / closing cylinder 430. [

In order to solve the above problem, the present invention further includes a locking cylinder 440 which can stop the forward and backward movement of the rod while accommodating the rod 432 in the lower part of the opening / closing cylinder 430, 420 can be prevented from being opened. When the locking cylinder is used as described above, the opening / closing cylinder having a small capacity can be used.

Specifically, the locking cylinder 440 may include a housing 441, a slider 442, and a locking pad 443, as shown in FIG.

The housing 441 is attached to the opening / closing cylinder 430, and a part of the rod 432 is received while the rod 432 passes through the housing. And an injection port 441a through which a pneumatic or hydraulic pressure can be supplied to one side is formed.

A slider 442 is installed inside the housing 441 so that the slider 442 slides up and down along the rod 432 between the rod 432 accommodated in the housing 441 and the housing 441. [ It is possible.

As shown in the figure, the slider 442 has a ring 432 which passes through the rod 432 at its center, has an inner circumferential surface in contact with the outer circumferential surface of the rod 432, and an outer circumferential surface in contact with the inner circumferential surface of the housing 441 A body 442a and a pressing member 442b extending from the body 442a and having a cylindrical shape through which the rod 432 penetrates. A gap is formed between the pressing member 442b and the rod 432. [

The locking pad 443 is provided in the housing 441 and is disposed adjacent to the slider 442. At least one of the locking pads 443 may be provided and may be disposed around the rod 432 at regular intervals.

At this time, the locking pad 443 is rotatably installed in the direction of widening to the outside of the rod 432, and is kept spaced apart from the outer circumferential surface of the rod 432 by a predetermined distance. That is, a gap is formed between the outer circumferential surface of the rod 432 and the locking pad 443. Preferably, the inner surface of the locking pad 443 may be made of a material having high friction.

The body 442a of the slider 442 is moved along the rod 432 like the piston when the pneumatic or hydraulic pressure is supplied through the injection port 441a of the housing 441 and the pressing member 442b ). When the end of the pressing member 442b is moved, the locking pad 443 is inserted between the pressing member 442b and the rod 432 and pressed so that the locking pad 443 rotates inward, Respectively.

Preferably, the end of the pressing member 442b may be formed with an inclined surface 442c to taper inward. That is, as the pressing member 442b rises, the inclined surface 442c acts like a wedge to reliably press the pressing member 442b, so that the rod 432 can be prevented from moving.

The end of the locking pad 443 may be inclined so as to be in close contact with the inclined surface 442c of the pressing member 442b.

Hereinafter, the operation of the present invention will be briefly described with reference to FIG. 4 is an operational state diagram of the locking cylinder of the present invention shown in Fig.

The ram noodle transferred by the ram noodle transfer device 200 is discharged into the pressure vessel 410 and the soup can be discharged by a separate sour supply device (not shown). Alternatively, the soup may be supplied with the hot water in a premixed state in the hot water.

When the hydraulic or pneumatic pressure is injected into the upper injection port 430a of the opening / closing cylinder 430, the piston 431 is lowered and the pressure cap 420 coupled to the rod 432 is closed.

When the pressure lid 420 is completely closed, a load is applied to the opening and closing cylinder 430, and the driving of the opening and closing cylinder 430 is stopped by detecting the load. At the same time, the locking cylinder 440 is operated to fix the rod 432 by locking it.

That is, when the hydraulic or pneumatic pressure is supplied through the injection port 441a of the locking cylinder 440, the slider 442 is raised and the end of the pressing member 442b of the slider 442 is raised, So as to be brought into close contact with the rod 432. Thus, the rod 432 will not move.

Hot water and compressed air are supplied from the high-pressure hot water supply device 300 to the inside of the pressure vessel 410 through the air hole 421. The hot water is supplied in a predetermined amount so that one of the hot water can be cooked, and the compressed air is supplied by compressed air, so that the compressed air can be supplied at about 2 to 3 atmospheres.

At this time, even if a high pressure is applied to the pressure vessel 410, the rod 432 can not rise and is fixed, so that the pressure lid 420 can be kept completely closed during the cooking time without opening or gaps .

When the supply of hot water and compressed air is completed, the heater 411 of the pressure vessel 410 is heated to cook the ramen under a high pressure.

As described above, since the pressure inside the pressure vessel 410 is kept at a high level, water is boiled at a high temperature of 100 ° C or more. Therefore, more heat is applied at 100 ° C under atmospheric pressure, It can be cooked in the minute.

When cooking of the ramen is completed, the steam discharge hole 422 is opened, and the steam is gradually discharged by opening the valves in order from the first to the fourth.

When the steam is discharged, the hydraulic pressure or the air pressure is removed through the inlet 441a of the locking cylinder 440, so that the slider 442 is lowered, so that the locking pad 443 is resiliently expanded outward. The piston 431 and the rod 432 are raised while the lock 432 is released and hydraulic or pneumatic pressure is supplied through the lower injection port 430b of the opening and closing cylinder 430 and the pressure cap 420 Is opened.

Finally, the operation of the ramen delivery device 600 causes the pressure vessel 410 to be dispensed to the ramen container C which is cooked while being tilted and the soup is waiting on the lower side.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, as well as the appended claims.
