In general, packaging containers such as carton packs for juice, milk, or soft drinks do not transmit light, so they are advantageous in preserving nutrients that are destroyed when exposed to sunlight, so they are usually made of paper-like materials. .

A paper package is a parallelepiped-shaped package for liquid or pourable food products in its typical shape, which is made by folding and sealing laminated strip packaging material.

The packaging material has a multilayer structure and comprises a base layer which can be defined as a layer of a fibrous material, for example paper or mineral-filled polypropylene material, substantially for stiffness and strength; and a plurality of layers of a heat-sealing plastic material, for example a polyethylene film, covering both sides of the base layer.

In the case of aseptic packages for long-term storage products such as UHT milk, the packaging material also comprises a layer of gas- and light-barrier material, for example aluminum foil or ethyl vinyl alcohol (EVOH) film, They are superimposed on a layer of heat-sealing plastic material and covered with another layer of heat-sealing plastic material which in turn forms the inner face of the package in contact with the food product.

As is known, paper-like packages are produced on fully automatic packaging machines, which, after forming a seal, are filled with sterilized or pasteurized food products, sealed and sealed along equally spaced cross sections. It is cut and mechanically folded to form each parallelepiped-shaped package.

On the other hand, although the use of carton packs is increasing according to regulations on the use of disposable packaging containers, there are many problems in the use of carton packs being limited due to sealing problems in companies that sell food products such as juice, milk, or beverages.

It may include a sealing unit 150 that is installed on the end side of the support rod 110 and the pair of rods to close the packaging container 10 and seal it by heating.

First, the case 100 is molded from a metal material or synthetic resin material, and the front and rear plates 103 and 104 are vertically installed on the base plate 102 of the bottom surface, and the front and rear plates 103 and 104 of the The upper plate 105 is installed at the upper end, and both side plates 106 may be installed laterally between the front and rear plates 103 and 104 .

Therefore, it forms a rectangular parallelepiped, and as shown, there are openings in the front and rear plates 103 and 104, the top plate 105 and the side plate 106, but they may be blocked, and a finishing material may be installed on the entire surface.

In particular, the base plate 102 was designed to have a certain height in a shape facing a “C” in the width direction, and the vibration caused by driving was minimized from being transmitted to the floor.

And inside the case 100, a vertical plate 107 may be installed vertically from the base plate 102 as shown in FIG. 2, and the vertical plate 107 has a pair of rods 110 and a support rod ( 110) is supported.

2 or 4 in which some of the front and rear plates 103 and 104, the top plate 105, and the side plate 106 of the case 100 are removed, it is described with reference to the upper side of the inner side of the case 100. A pair of rods 110 may be installed.

The pair of rods 110 are a first rod 110a and a second rod 110b, and may be round rods having a predetermined length, respectively, and both ends of the first rod 110a and the second rod 110b are Inserted into the thick plate bushing 112 installed on the back plate 104, respectively, installed horizontally through the bushing 114 installed on the vertical plate 107 and the bushing 114 installed on the front plate 103, The first rod 110a and the second rod 110b may be installed side by side while being spaced apart by an appropriate distance in a horizontal state.

Here, a restoring spring (not shown) is installed inside the thick plate bushing 112 to support the end sides of the first rod 110a and the second rod 110b.

The restoration spring may be a device for returning the retracted first rod 110a and the second rod 110b described below in the forward direction by elasticity.

And the bushings 114 serve to guide and support the first rod 110a and the second rod 110b to move forward and backward.

Again, a pair of rollers 120 may be installed facing each other between the first rod 110a and the second rod 110b as in FIG. 2 or FIG. 4 .

The pair of rollers 120 may also be a first roller 120a and a second roller 120b, and the first roller 120a has both ends between the first rod 110a and the second rod 110b. It is connected to the shaft and moves like the first rod 110a and the second rod 110b, and a bearing, etc. (not shown) is installed on the shaft to enable rolling contact.

In addition, both ends of the second roller 120b may be fixed to the vertical plate 107 .

The distance between the pair of facing rollers 120 may be preferably as long as the elevating end 136 of the driving unit 130 to be described below can enter.

In addition, the driving unit 130 moves the pair of rods 110 backward while moving up and down between the rollers 120 facing each other.

The driving unit 130 may again be largely composed of a lifting end 136 connected to the cylinder 131 and the cylinder rod 132 .

The cylinder 131 may be an air or fluid cylinder, electrically connected, and may be operated and controlled by a controller.

And the lifting end 136 may be integrally installed on the cylinder rod 132 extending from the cylinder 131 in the axial direction.

And a stopper 134 in the form of a nut is installed on the cylinder rod 132 to limit the lifting movement.

Here, the cylinder may be composed of a driving motor and a lead screw.

The overall shape of the lifting end 136 is “┗┛” when viewed from the front, and has an open front, rear, and upper end, and one surface in the rear direction of the front and rear faces, that is, the rear bushing 114. It may be formed of an inclined surface 136a whose width becomes narrower as one surface faces toward the upper end.

When viewed from the side, the inclined surface 136a having a narrower upper end is formed, so that when the lifting stage 136 is lifted, the width increases while digging between the pair of rollers 120 as an inclined surface 136a. Like the first roller 120a, the first rod 110a and the second rod 110b are retracted.

The first rod 110a and the second rod 110b are retracted while compressing the return spring of the rear bushing 114 .

The retraction operation of the first rod 110a and the second rod 110b causes a close contact operation with the sealing part 150 .

Meanwhile, the support rod 110 may be installed on the lower side of the first rod 110a and the second rod 110b.

The support rod 110 is also in the form of a round bar, and is fixedly installed on the vertical plate 107 , and a circular plate having a relatively large area is installed on the round bar to be supported by the vertical plate 107 .

And the support bundle 142, the diameter of which is enlarged, is installed on the support rod 110 to face the front plate 103 of the case 100, and the end side of the support bundle 142 protrudes toward the front plate 103 and has a narrow width. The supporting end 144 is integrally formed.

The support end 144 is positioned to protrude from the front plate 103 from the support bundle 142 , and supports the upper end surface of the packaging container 10 loaded for sealing at that position.

Therefore, the end surface of the support end 144 is preferably a vertical surface, it is preferable to be formed to have a larger area than the upper end of the packaging container (10).

In addition, in another embodiment, the support end 144 is equipped with a sterilization means (not shown) to sterilize the inner or upper sealing surface of the packaging container 10 before sealing the packaging container 10 .

And the end side of the pair of rods 110 may include a sealing unit 150 for sealing the end of the packaging container 10 when the rod 110 is retracted by heating while closely adhering to the support end 144 .

Furthermore, the sealing part 150 is provided with a sealing end 152 installed at a position passing through the front plate 103 of the case 100, and a carton pack packaging container 10 protruding from the lower end of the sealing end 152. A vertical heating surface (152a) that heat-seals the top, and a sealing portion of the packaging container (10) and / or the beverage is filled in the upper portion leading to the bottom from the heating surface (152a) before fusion of the packaging container (10) It may include an ultrasonic vibration surface 152b for generating ultrasonic vibration.

The sealing end 152 has a rectangular parallelepiped shape having a predetermined area and is vertically installed, and a heating surface 152a may be formed to protrude from the sealing end 152 on one side of the lower end toward the front plate 103 .

The heating surface 152a is in the form of a jaw as in FIG. 7 , and by heating the sealing part, which is the upper end of the packaging container 10 , the thermoplastic resin layer is softened or melted and pressed together with the supporting end 144 to be sealed. will do

Therefore, the heating surface 152a is the same as a heating heater, is electrically connected, and may be configured in a pattern in which a plurality of circular or slit-type small holes for ejecting hot air are disposed.

In addition, the ultrasonic vibration surface 152b may be an ultrasonic vibrator, and the generated vibration may propagate to the upper sealing portion of the packaging container 10 through the inclined wall of the carton pack packaging container 10 .

Ultrasound is a sound wave, that is, "a wave transmitted to its surroundings by vibrating something that makes a sound", and is a sound wave with a frequency of about 30 Hz to 20 kHz or higher.

It has the function of welding welding, and the inside of it heats up due to the friction of the sealing part by ultrasonic vibration or the repetition of the compression received by the material itself, and the temperature rises. can

In addition, the liquid supported on the inner or outer surface of the object is atomized by ultrasonic waves, and the liquid is removed from the object by generating heat by internal friction.

Here, ultrasonic vibration is applied to the sealing part of the packaging container 10 and/or the upper part of the container filled with beverage to separate the liquid from the inner wall of the container to which the liquid is attached (the part to be sealed) without heating the contained contents, and again vertical Drop it into the container without returning to the wall of the That is, since it does not generate heat, the solid component of the beverage is dropped as it is without concentration or drying, so that it returns to the inner surface of the container and contamination can be prevented.

In addition, although the beverage filled in the packaging container 10 brings air into the liquid and creates foam, the wave of pressure change caused by vibration and the propagating elastic wave collide with the foam of the beverage filled in the upper part of the container and cause the thin liquid film to Can crack and break bubbles.

On the other hand, a control unit (not shown) may be installed on the front or side surface of the case 100 , wherein the control unit determines the size of the packaging container 10 and the size of the sealing part or the sealing speed and heating temperature of the packaging container 10 and It will control the operation of the compression force, etc.

In addition, the control unit includes an input unit into which the information value of the packaging container 10 is input, a calculation unit for calculating a movement or spacing adjustment distance based on the value input by the input unit, and determining whether the cylinders are operated according to the result calculated by the calculation unit It may include an output unit for controlling the rotation speed.

Furthermore, the control unit is in charge of sequence control (eg, controlling heat-up, operation mode, cool-down, etc.), feedback control, and EBOP control, and can change operating variables through real-time monitoring during operation, state control and predictive diagnosis can be performed.

In addition, the control unit may be connected to the upper control system through an external communication network (eg, Ethernet). The upper control system is connected to the controllers of a plurality of fuel cell systems and is responsible for integrated control of parallel operation for each unit module (6/24/120kW) and load sharing in case of unit module failure.

The stability and reliability of the entire system can be improved based on the state monitoring of the upper control system through the control unit. It is also possible to operate in which priority is given to desired items among the lifespan of the stack module and power generation output. Because unit modules can be replaced, the continuity of operation of the system is also ensured. For example, various methods such as individual independent operation, integrated parallel operation, and load variable operation may be supported.

Furthermore, it may include a management server capable of managing the control unit. The management server may be a server operating a website and/or a mobile application related to a platform for controlling the sealing device for carton pack packaging containers of the present invention, as a 'central server' or a 'control server' may be called.

The operation of the sealing device for a carton pack packaging container according to the present invention having the above configuration will be described with reference to FIG. 5 or FIG. 6 .

The sealing portion of the packaging container 10 is loaded so as to be in close contact with the support end 144 side.

When the cylinder 131 is operated by the application of power in the following state, the cylinder rod 132 and the lifting end 136 start lifting.

The lifting and lowering of the lifting end 136 is moved between the first roller 120a and the second roller 120b, and the second roller 120b is fixed by the gradually widening inclined surface 136a. As the roller 120a is pushed along the inclined surface 136a, the first rod 110a and the second rod 110b connected together are retracted while compressing the return spring of the thick plate bushing 112.

Here, when the cylinder rod 132 rises by about 20 mm by the operation of the cylinder 131 , the pair of rods 110 are retracted to a length of about 4 mm.

For example, when a force of 50 kg is applied to the stroke of the cylinder rod 132, the sealing unit 150 presses the pressure to 250 kg. That is, it is about 1:5 in proportion to the stroke.

Therefore, as the rod 110 retracts, the sealing portion of the packaging container 10 supported by the support end 144 is compressed, and at the same time as the compression, the vibration of the ultrasonic vibrator in the ultrasonic vibration surface 152b is sealed through the inclined wall of the packaging container. spread to the part.

The ultrasonic vibrator is in contact with the outer surface of the packaging container 10, and imparts ultrasonic waves to the top of the container from the outside to the inside. Since the vessel wall is relatively rigid, vibrations propagate through the vessel wall to the seal of the vessel top.

As described above, when the sealing part is sealed with heat sealing after filling of the packaging container 10 for beverages, etc., the sealing property or sealing property is secured by removing the adhesion of the liquid or its foam from the heat sealing surface and preventing adhesion. can do.

And on the heating surface 152a, heat is ejected in a pattern in which a large number of circular or slit-type small holes are arranged to heat the sealing part, which is the upper end of the packaging container 10, to soften or melt the thermoplastic resin layer to form the support end 144 and They are pressed together and sealed.

When the sealing is completed, the cylinder rod 132 and the lifting end 136 start to descend by the operation of the cylinder 131 by the controller, and when the lowering of the lifting end 136 is completed, the pair of rods 110 is moved forward by the return spring in the thick plate bushing 112 and returned to its original position.

According to the above-mentioned bar, the sealing device for the carton pack packaging container is movable, so it can be easily used in a small business.

In addition, with the sealing structure using the stroke structure, the structure is simple and the pressure of the press for sealing can be raised to the maximum value, and the sealing force is excellent by sealing using heating and ultrasonic waves.

The sealing device for carton pack packaging containers can be used in small restaurants, etc., and can be stacked and transported in a packaging container with an open top that is not sealed, thereby reducing logistics costs and improving storability.

In the detailed description of the present invention, although specific embodiments have been described, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
