Description

Vacuum packaging device for food

The present invention relates to a vacuum packaging device for food, and more particularly, to a vacuum packaging device for food capable of forming a vacuum inside the packaging product by sucking the inside of the packaging product.

In general, a vacuum packaging machine is a device that forms the inside of a plastic bag containing food and the like in a vacuum state and then heat-seals it, so that the food or the like can be stored in a vacuum state for a long time. These vacuum packaging machines are generally divided into a chamber type and a nozzle type, and vacuum packaging machines of various structures are currently known. In addition, the vacuum packaging machine is equipped with a heating wire for sealing the inside of the plastic bag after forming a vacuum atmosphere. This vacuum packaging machine uses a plastic bag with an opening formed at one end.

A conventional chamber-type vacuum packaging machine includes a base member having a chamber formed on its upper surface, a cover member rotatably hinged to the base member, and a gasket mounted around the chamber. In such a vacuum packaging machine, when the chamber is closed by rotating the cover member, the portion adjacent to the hinge coupling point of the cover member and the base member of the gasket portion touches first and the farthest portion touches last. Accordingly, a region adjacent to the hinge joint receives a relatively large compressive force, and a region farther from the hinge receives a relatively weak compressive force.

For this reason, when it is used for a long time, the portion of the gasket adjacent to the hinge joint point is pressed and deformed the most, causing a problem in that the sealing of the chamber is not performed well.

Hereinafter, the structure of the vacuum packaging apparatus 100 for food according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6 .

The vacuum packaging apparatus 100 for food according to an embodiment of the present invention has an open top and has an internal space 110a in one direction so as to cover the open upper portion of the body 110 and the body 110 . , referred to as the longitudinal direction) and the cover portion 120 rotatably coupled to the body portion, is disposed in the inner space 110a, the packaging article 10 and the food 20 accommodated in the packaging article is seated The cutting unit 140 movably coupled from the lower surface of the cover unit 120 toward the receiving unit 130 so as to cut at least a portion of the unit 130 and the packaging product 10 seated on the receiving unit 130 . ), at least a portion of the packaging product 10 can be inserted into the inside, and the suction unit 150 and the packaging product 10 disposed in the inner space 110a to suck the internal gas of the packaging product 10 is pressed It may include a pressing part 160 coupled to the lower surface of the cover part 120 to be movable toward the seating part 130 so as to be able to do so.

Here, the packaging product 10 may include, for example, a vinyl formed of a film material, and the food 20 may include, for example, a processed meat product. However, the packaging article 10 and the food 20 are not limited thereto, and may vary.

The body portion 110 has an open upper portion, has an internal space 110a communicating with the open upper portion, extends in the longitudinal direction, has a width in an intersecting direction, and is formed as a structure having a height in the vertical direction. can Here, the crossing direction may be a direction horizontally orthogonal to one direction, and the vertical direction may be a direction perpendicular to the longitudinal direction and the crossing direction.

In addition, the body portion 110 may include a dividing wall 111 to divide the inner space 110a into a plurality of spaces. Accordingly, the body portion 110 may divide the inner space 110a into a plurality of spaces separated from each other. Meanwhile, the seating part and the suction part 150, which will be described later, may be respectively provided in the plurality of spaces described above. Accordingly, in the vacuum packaging apparatus 100 for food, a packaging product containing food continuously therein may be vacuum-packed.

In addition, the body part 110 may include a connection arm 112 . One end of the connecting arm 112 may be rotatably coupled to the outer wall of the body 110 , and the other end may be rotatably coupled to the cover 120 to be described later.

The cover part 120 is rotatably coupled to the body part 110 , and may cover the open upper part of the body part 110 . That is, the cover part 120 may cover the upper part of the body part 110 to seal the inner space 110a.

Meanwhile, the cover part 120 may be formed by recessing its lower part inward. Accordingly, a pressing unit 160 to be described later may be installed in the recessed inside of the cover unit 120 .

The seating part 130 is disposed in the inner space 110a of the body part 110 , and the packaging article 10 and the food contained in the packaging article 10 may be seated therein.

The cutting unit 140 is movably coupled to the cover unit 120 , and can cut a portion of the packaging product 10 in which the vacuum state is formed. The cutting part 140 may be formed to be movable in the vertical direction so as to move from the cover part 120 toward the seating part 130 . Here, the cutting unit 140 may cut the packaging product 10 at a position adjacent to the portion inserted into the suction unit 150 of the packaging product 10 . For example, the cutting unit 140 may cut the packaging product 10 by heat-sealing the packaging product 10 . Accordingly, the packaging article 10 in which the gas inside is discharged to the outside is cut and closed, and it is possible to maintain a vacuum state therein. That is, the cutting unit 140 seals the open portion of the packaging product 10 (that is, the portion inserted into the suction unit 150), and the inside of the packaging product 10 in which the vacuum state is formed. It can be kept in a vacuum. In this case, the packaging product 10 is in close contact with the food 20 , and its volume may be minimal.

The suction part 150 may be disposed in the inner space 110a so that at least a portion of the packaging article 10 can be inserted therein and can suck the internal gas of the packaging article 10 . At least a part of the suction part 150 may be disposed on the side of the seating part 130 , and at least a part of the suction part 150 may be disposed on the upper side of the seating part 130 . In addition, the suction unit 150 may insert the opened portion of the packaging article 10 therein. The suction unit 150 may include a suction pipe 151 , a communication pipe 152 , a suction pump 153 , and a fixed pipe 154 .

At least a portion of the suction pipe 151 is disposed on the upper side of the seating portion 130 , extends in the longitudinal direction, and may be inserted into the open portion of the packaging product 10 .

The communication pipe 152 may be disposed on the side of the seating part 130 and extend in the vertical direction, the upper part of which may be in communication with the suction pipe 151 , and the lower part thereof may be communicated with the suction pump 153 . That is, the communication pipe 152 may be a passage through which the suction pipe 151 moves the gas inside the suctioned packaging product 10 to the suction pump 153 .

On the other hand, the communication pipe 152 may be configured to control the flow of gas supplied from the packaging article 10, the amount of internal gas is reduced by the suction pump (153).

In general, vortex refers to a phenomenon in which a flowing fluid collides with a stationary fluid at an interface between a flowing fluid and a stationary fluid and rotates in the opposite direction to the moving direction. The vortex phenomenon may occur when the fluid is discharged from the inside of the pipe to the outside of the pipe or where the width of the passage through which the fluid moves is changed from a narrow place to a wide place. Accordingly, as the gas passing through the suction pipe 151 flows into the communication pipe 152 , a vortex phenomenon may occur in the gas.

If a vortex phenomenon occurs in the gas inside the communication pipe 152, the suction pump 153 may not be able to smoothly suck the gas, and the internal gas of the packaging product may not be effectively discharged, so that the inside of the packaging product is damaged. You may not be able to create a vacuum. Accordingly, the inside of the communication pipe 152 may be configured to control the flow of the gas supplied from the suction pipe 151 . To this end, the communication pipe 152 may include a first pipe 152a, a second pipe 152b, and a third pipe 152c.

The first pipe 152a is connected to the suction pipe 151 , and may be a passage through which gas flows into the communication pipe 152 . Here, the inner diameter of the first pipe (152a) may be formed to be equal to or smaller than the size of the inner diameter of the suction pipe (151).

The second pipe 152b is connected to the suction pump 153 , and may be a passage through which the gas introduced into the communication pipe 152 is discharged to the suction pump 153 . Here, the inner diameter of the second pipe 152b may be formed to be smaller than the size of the inner diameter of the first pipe 152a. That is, the second pipe 152b may have a smaller inner diameter than the first pipe 152a and may be connected through the third pipe 152c.

In general, when fluids in a connected pipe have the same flow rate, the moving speed may be relatively slow as the cross-sectional area passing through is wider, and the moving speed of the fluid may be relatively fast as the cross-sectional area passing through is narrower. Accordingly, since the internal pressure may be lowered as the speed of the fluid increases, the pressure in the section having a relatively narrow cross-sectional area may be lower than the pressure in the section having the relatively wide cross-sectional area. Accordingly, the pressure in the second pipe (152b) may be higher than the pressure in the first pipe (152a).

Meanwhile, the inlet of the suction pump 153 connected to the second pipe 152b may have the same size as the inner diameter of the second pipe 152b.

The third pipe 152c is respectively connected to the first pipe 152a and the second pipe, and may serve as a passage connecting the first pipe 152a and the second pipe 152b. Here, the third pipe 152c may be formed in a shape in which the inner diameter of the third pipe 152c gradually decreases along the gas movement direction (ie, the vertical direction in the drawing) from the first pipe 152a to the second pipe 152b. In addition, the third pipe 152c may include injection plates 152ca and 152cb capable of adjusting the irregular flow of gas to a constant flow therein.

The injection plates 152ca and 152cb pass through the separation membrane 152ca and the separation membrane 152ca having the same diameter as any one of the inner diameters of the third pipe 152c, and a plurality of injection holes 152cb having a length in the vertical direction. may include Hereinafter, a case in which the diameter of the separation membrane 152ca is formed to have the same length as the shortest inner diameter among the inner diameters of the third pipe 152c will be exemplarily described.

On the other hand, as described above, after passing through the suction pipe 151, a vortex phenomenon may occur in the gas introduced into the first pipe 152a. Accordingly, it is necessary to form a smooth gas flow of the gas from the rear end of the injection plates 152ca and 152cb to the suction pump 153 through the injection plates 152ca and 152cb.

More specifically, when the gas flows into the first pipe 152a, the gas may try to move to the second pipe 152b through the third pipe 152c. At this time, the gas may be temporarily stopped by the separation membrane 152ca provided in the third pipe 152c. That is, the gas may be temporarily condensed by the separation membrane 152ca while staying at the front end of the separation membrane 152ca.

On the other hand, the internal pressure of the first pipe 152a and the second pipe 152b may be lower than the internal pressure of the first pipe 152a due to the size difference between the inner diameters of the first pipe 152a and the second pipe 152b, and the third pipe 152c may have a lower internal pressure. The internal pressure of the second pipe 152b may be lower than the internal pressure of the pipe 152c. Accordingly, depending on the characteristics of the fluid flowing from high pressure to low pressure, the gas temporarily condensed at the front end of the separation membrane 152ca may be rapidly discharged to the injection hole 152cb formed through the separation membrane 152ca. That is, the separation membrane 152ca compresses the gas instantaneously and discharges the gas through the injection hole 152cb to form a flow of the gas in a predetermined direction in the second pipe 152b, which is the rear end of the injection plates 152ca and 152cb. can Accordingly, a smooth flow of gas to the suction pump 153 can be formed.

In addition, the injection hole 152cb may be provided in a shape in which the inner diameter decreases along the moving direction. Accordingly, as the gas passes through the injection hole 152cb, the moving speed may gradually increase. Accordingly, the gas may more smoothly and quickly pass through the injection hole 152cb to more effectively form the gas flow in the second pipe 152b in a constant direction. Here, the structures and shapes of the first pipe 152a, the second pipe 152b, and the third pipe 152c are not limited thereto and may vary.

The suction pump 153 may be coupled to the end of the communication pipe 152 so as to form the inside of the packaging product 10 in a vacuum atmosphere. The suction pump 153 is disposed below the inner space 110a, and may be located on the side of the seating unit 130 .

The fixed pipe 154 is disposed to be spaced apart from the suction pipe 151 along the circumference of the suction pipe 151, and a portion of the packaging product 10 drawn between the inner circumferential surface and the outer circumferential surface of the suction pipe 151 is sucked It can be attached to the pipe (151). The fixing pipe 154 may include a body member 154a, a fixing member 154b, and a driving member (not shown).

The body member (154a) has a larger diameter than the suction pipe (151), is disposed to surround the circumference of the suction pipe (151), the end may be coupled to the outer peripheral surface of the suction pipe (151). That is, the body member 154a may be formed in a cylindrical shape in which one side facing the seating portion 130 is opened and the other side opposite to the one side is closed based on the longitudinal direction. For example, the body member 154a may be formed in an O-ring shape.

The fixing member 154b is disposed along the perimeter of the penetrated inside of the body member 154a and may be rotatably installed toward the outer circumferential surface of the suction pipe 151 . That is, the fixing member 154b may be disposed along the periphery of the inner circumferential surface of the body member 154a, and may be formed to be movable toward the center of the inner peripheral surface of the body member 154a penetrated by a driving member to be described later. . For example, the fixing member 154b may be provided in plurality, and may be arranged to surround the circumference of the suction pipe 151 at the perforated inner edge of the body member 154a. Accordingly, the fixing member 154b may be installed rotatably in a direction perpendicular to the direction in which the gas moves toward the central portion of the body member 154a penetrated, that is, the suction pipe 151 .

More specifically, the fixing member 154b may be formed in a plate shape. Here, some of the plurality of fixing members 154b may overlap each other. The fixing members (154b) are disposed at an even angle with respect to the central axis of the body member (154a) in the penetrating interior of the body member (154a), and in a direction perpendicular to the movement direction of the gas (ie, cross direction or longitudinal direction) is installed with For example, each of the fixing members 154b is rotatably supported on one side by a rotation shaft provided on the body member 154a, and may be rotated and deployed along a direction perpendicular to the movement direction of the gas.

On the other hand, the other side of each of the fixing members (154b) may be installed so that some overlap each other. That is, each of the fixing members 154b is a fixing member 154b so that when the packaging product 10 is inserted into the penetrated interior of the body member 154a, the packaging product 10 is in close contact with the outer circumferential surface of the suction pipe 151. The overlapping part can be rotated by increasing or decreasing at a uniform rate. Accordingly, the fixing member 154b presses the packaging product 10 inserted between the body member 154a and the suction pipe 151 toward the suction pipe 151, and the packaging product 10 is sucked into the suction pipe 151 ) can be attached to the outer circumferential surface of Accordingly, the packaging product 10 is in close contact with the suction pipe 151, the gap between the packaging product 10 and the suction pipe 151 disappears, and the inside of the packaging product 10 is more effectively formed in a vacuum atmosphere. can

The driving member is connected to the fixing member 154b to move the fixing member 154b. For example, the driving member may include a rotating body, a motor, first teeth, second teeth, and third teeth. The rotating body may be rotatably installed along the inner edge of the body member (154a). The center of the rotating body is opened to allow the coolant to pass therethrough, and the open central region is disposed to correspond to the suction pipe 151 disposed coaxially with the body member 154a in the penetrated interior of the body member 154a.

The rotating body may receive a driving force from the motor through the first and second teeth. A predetermined screw thread is formed on the outer peripheral surface of the rotating body. The thread engages a thread formed in the second tooth. Accordingly, when the second gear rotates, the rotating body may rotate. In this case, the first tooth is provided on the central shaft of the motor and can be directly rotated by the motor. Accordingly, the first and second teeth and the rotating body may be rotated in engagement with each other.

In addition, a predetermined screw thread is formed on the inner peripheral surface of the rotating body. The thread engages a thread formed in the third tooth. Accordingly, the third tooth rotates by the rotation of the rotating body. That is, by the rotation of the first rotating body, the third tooth rotates inside the rotating body.

In addition, the second spring 162c may serve to prevent the upper side of the second rack gear 162b from being worn by colliding with the inner wall of the cover unit 120 .

The pressurizer 163 is coupled to the lower portion of the first driver 161 and the lower portion of the second driver 162, respectively, and both ends are supported by the first driver 161 and the second driver 162, and the seating portion ( 130) and the opposite side may be formed of an elastic material. The pressurizer 163 may include at least one of a natural rubber, a sponge, a synthetic rubber, a heat-resistant silicone rubber, and a tube so that its shape can be changed when its lower part comes into contact with food. Accordingly, both ends of the pressurizer 163 are sequentially descended by the first actuator 161 and the second actuator 162 , and the packaging article 10 and the food 20 stored in the packaging article 10 come into contact with each other. can be Thereafter, the pressurizer 163 descends further, and may be in contact with the upper surface of the seating portion 130 , wherein the lower portion of the pressurizer 163 is depressed inwardly in response to the shape of the food and is on the outer circumferential surface of the packaging product 10 . can be adhered to. Accordingly, the gas inside the packaging article 10 can more effectively escape to the suction pipe 151 by the pressurization of the pressing unit 160 . Accordingly, the inner surface of the packaging product 10 may be in close contact with the outer surface of the food 20 , and the volume of the packaging product 10 may be minimized.

On the other hand, when the pressurizer 163 rises by the first actuator 161 and the second actuator 162 and returns to the original position, the packaging article 10 and the food 20 accommodated in the packaging article 10 . and the recessed portion may be returned to its original shape.

The controller 164 may be connected to the suction unit 150 and selectively control the operations of the first driver 161 and the second driver 162 according to the gas amount value sucked by the suction unit 150 . To this end, the controller 164 may include a measurement unit 164a, a determination unit 164b, and a control unit 164c.

The measurement unit 164a is connected to the suction pipe 151 and can measure the amount of gas passing through the suction pipe 151 . For example, the measurement unit 164a may be provided as a flow rate digital sensor.

The determination unit 164b compares the measurement values measured by the measurement unit 164a with preset first and second reference values to determine the driving timing of the first driver 161 and the second driver 162 . It may be connected to the measurement unit 164a. Here, when the measurement value measured by the measurement unit 164a is the same as the first reference value, the determination unit 164b may determine that it is the time when the first driver 161 is to drive. Also, when the measurement value measured by the measurement unit 164a is the same as the second reference value, which is a value greater than the first reference value, the determination unit 164b may determine that it is time for the second driver 162 to drive.

The control unit 164c may selectively control the driving of the first driver 161 and the second driver 162 according to the determination of the determination unit 164b. More specifically, when the gas is discharged from the inside of the packaging article 10 to the suction pipe 151, the gas amount value measured through the measurement unit 164a in the suction pipe 151 may gradually increase. At this time, when the determination unit 164b determines that the measured value is equal to the first reference value, the first actuator 161 is operated through the control unit 164c, and the packaging product ( 10) can be pressurized. That is, the pressurizer 163 may pressurize a relatively distant portion of the packaging article 10 based on the portion from which the gas is discharged.

Thereafter, as more gas is gradually discharged from the inside of the packaging article 10, the gas amount value measured through the measurement unit 164a in the suction pipe 151 may increase to a value greater than the first reference value. . At this time, when the determination unit 164b determines that the measured value is equal to the second reference value, the second actuator 162 is operated through the control unit 164c, and the packaging product ( 10) can be pressurized. That is, the pressurizer 163 may press a relatively close portion of the packaging article 10 based on the portion from which the gas is discharged. Accordingly, the pressurizer 163 pressurizes the packaging article 10 as a whole, and all of the gas therein may be discharged to the suction pipe 151 . Therefore, it is possible to more effectively form the inside of the packaging article 10 in a vacuum atmosphere. Accordingly, the packaging article 10 can be in a state in close contact with the food 20 . The food 10 may be vacuum-packed by the packaging article 10 .

In this way, the pressing unit pressurizes the packaging article in the process of the suction unit introducing the gas inside the packaging article, and the gas inside the packaging article may be discharged to the outside. Accordingly, it is possible to more effectively form the inside of the packaging article in a vacuum state. In addition, the pressurizing unit may pressurize the packaging article from a position relatively far from the position where the gas is sucked in the packaging article to push the gas inside. Accordingly, it is possible to completely discharge the gas inside the packaging article by gradually pressing the pressurizing unit from a position far from the position where the gas is sucked toward the position where the gas is sucked. In addition, during the process of the suction unit sucking the gas inside the packaging article, it is possible to suppress or prevent the occurrence of a vortex in the gas sucked from the packaging article in which the amount of internal gas is reduced by the suction pump.
