The present invention relates to a vacuum packaging machine having a side hinge,

In more detail, a heater (or vacuum chamber) forming member having a length corresponding to the length of the inlet of the vacuum packaging bag made of a heat-adhesive resin and a heater are arranged, and the rectangular shape corresponding to the shape of the sealed space and the heater is arranged. In the arrangement of the hinge for opening and closing the base and the hood having a shape, it is possible to separate from the conventional "back hinge" arrangement and adopt the "side hinge" arrangement so that the heater can be used exclusively for sealing the vacuum bag. It relates to a vacuum packaging machine significantly widened.

The vacuum packaging machine is used in the specialty restaurants or food stores to prevent contamination by air contact of the contents and improve the convenience of storing by vacuum packing the contents such as food or cooked food in the packaging bag. It is developed and widespread.

In describing the vacuum packaging machine in the present specification, the direction reference will be described with reference to FIGS. 1A and 1B showing the vacuum packaging machine according to the present invention. The rectangular shape of the hood 20 has a length corresponding to the length of the inlet of the vacuum packaging bag. When the inlet (B1) of the vacuum packaging bag (B) is put into the position of the base 10 engaged with the sealing space forming member 30 arranged in a divided manner, the front and rear sides are divided in particular according to the traveling direction of the packaging bag. In the vacuum packaging machine, the sealed space (S) side is set to the rear, and the heater 50 is set to the front, and the top and bottom divided based on the direction of gravity.

Conventional vacuum packaging machine is a combination of the base and the hood is made by a hinge located on the rear or both sides, for example

U.S. Patent No. 4,941,310 to Tillia (August 17, 1990) `` APPARATUS FOR VACUUM SEALING PLASTIC BAGS '' (Related Korean Patent No.0109619 (1996.12.23),

Korea Utility Model Registration No. 0165428 (1999.10.18) by Chu Yeon 『Vacuum Packing Machine』,

Korea Utility Model Registration of the Eiffel Industry No. 0322449 (2003.07.28) 『Vacuum Packing Machine』,

Such a conventional vacuum packaging machine is rotated about the longitudinal direction of the rear side to the base and the hood is engaged, so it is called a vacuum packaging machine of the "back hinge" arrangement method, which is a vacuum packaging machine according to the present invention in one direction of one side This is a key difference in contrast to the "side hinge" arrangement, which is pivoted about the axis to engage the base and the hood.

The vacuum packaging machine adopting the “back hinge” arrangement method, which is a combination of the base and the hood, is a vacuum bag that sequentially passes through the heat seal at the inlet of the vacuum bag after vacuuming due to the discharge of the air inside the vacuum bag using the vacuum pump. It does not take into consideration the unique use of the heater in the vacuum packaging machine because it is properly configured for the packaging process.

That is, the conventional vacuum packaging machine is impossible to heat seal itself by being blocked by the rear hinge when a long spacing heat sealing without cutting the packaging bag without the vacuum process.

This problem is caused when the contents are put into the vacuum bag, the openings are sealed, and when the parts of the bag are heat-sealed, for example, when the heat-sealing part is formed with a crisscross for four minutes, Due to the hinge provided on the suture is impossible.

The present invention has been proposed to solve the problem of the conventional vacuum packaging machine of the "back hinge" arrangement.

Accordingly, an object of the present invention is to expand the application range of the vacuum packaging machine by enabling the exclusive use of the heater through the vacuum packaging machine of the "side hinge" arrangement method.

In another aspect, the present invention aims to separate the part for the heater and the part for the closed space forming member in the base and the hood separately to improve the unique usability of the heater in the vacuum packaging machine to be opened from the rotation shaft. .

In addition, the present invention is arranged with a plurality of nozzles at a predetermined interval in the sealed space so that the vacuum suction input is uniform throughout the sealed space, the liquid contents are sucked into the vacuum pump through the nozzle during the vacuum of the packaging bag to contaminate the pump, It is an object of the present invention to provide a vacuum packaging machine in which a confined space and a nozzle are arranged only in a hood to prevent the cause from being caused to prevent liquid contents from flowing into the nozzle by gravity.

Furthermore, the present invention provides a method of sealing multiple vacuum packaging bags using such a vacuum packaging machine.

In order to achieve the above object, a vacuum packaging machine having a side hinge according to the present invention has a rectangular base; A hood having a corresponding shape to cover an upper surface of the base and coupled through a hinge provided at the base and the side; A sealed space forming member formed when the base and the hood are engaged; A vacuum pump connected to a nozzle and a connection tube arranged in a sealed space formed by the sealed space forming member to generate a vacuum suction input in the sealed space during operation; A heater arranged in a rectangular shape on the base or the hood, or both, for heating and laminating the vacuum packaging bag; And a control unit for controlling the vacuum pump and the heater.

In addition, the vacuum packaging machine according to the present invention is the portion in which the heater is arranged and the portion having the sealing space forming member is rotated by the starting point of a separate rotation shaft provided on the side can be opened to the independent use function of the heater It is desirable to be able to further reinforce.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Figures 1a and 1b, the vacuum packaging machine having a side hinge (H1) (H2) according to the invention has a rectangular shape as a whole, the shape of the base 10 and the hood 20 The rectangular shape ensures a heater and a confined space that is at least longer than the width of the vacuum packaging bag.

The biggest feature of the vacuum packaging machine according to the present invention is the connection between the rectangular base 10 and the hood 20 covering the base 10 and the side hinge (H1) (H2) in contact with the support surface, such as sink, dining table, workbench, etc. It is made through).

The vacuum packaging machine according to the present invention is correlated with the vacuum process due to the "side hinge" (H1) (H2), whereas the conventional vacuum packaging machine of the "back hinge" arrangement is suitable for sequentially undergoing the post-vacuum heat sealing process of the vacuum packaging bag. 4a without, it is possible to make a long sparse heat seal B2 without cutting the wrapped bag B wound in the form of a roll R (in FIG. 4a, reference numeral B1 denotes the inlet of the bag). In addition, as shown in Fig. 4b, the contents (B3) are put into the vacuum packaging bag (B), and a portion of the packaging bag is heat-sealed (B2) (for example, the contents are packed in a state in which the inlet is sealed and cut). It is possible to thermally seal the vacuum packaging bag into ten minutes so that the vacuum packaging bag is not sandwiched between the sheets constituting the bag.

In the vacuum packaging machine illustrated in FIGS. 1A and 3, the vacuum pump 40, the sealed space S forming member 30, and the heater 50 which form the core of the vacuum packaging machine are all arranged in the hood 20. However, the present invention is not limited by the arrangement of the components.

In the portion of the base 10 which is engaged with the heater 50 arranged in the hood 20, a pressing member 51 made of a special synthetic resin such as heat-resistant silicon or Teflon is arranged.

The degree to which the heater 50 and the pressure member 51 are engaged to pressurize the inlet of the vacuum packaging bag is limited so as not to severely inhibit the suction of the air inside the vacuum packaging bag by the vacuum pump 40.

In addition, the member 30 for forming the closed space (S) formed when the base and the hinge is engaged is made of a long closed loop concave portion 31 provided in the hood 20, The circumference of the concave portion is provided with a packing member 33 for improving airtightness. In addition, a portion of the base 10 that closes the opening of the concave portion 31 to form a closed space S is also provided with a plate-shaped packing member 35 for improving airtightness.

The sealed space forming member may be provided only in the base, or may be modified in the form of a concave portion formed in both the base and the hood.

1A, 1B, and 3, a vacuum suction input is applied to the sealed space S formed when the base and the hood are engaged to allow air to be discharged through the inlet B1 of the vacuum packaging bag B. The vacuum pump 40 is connected to the nozzle 41 arranged on the upper surface of the concave portion 31 of the hood 20 through a connecting pipe 43.

In particular, a plurality of nozzles 41 connected to the vacuum pump 40 are formed at predetermined intervals in the sealed space S, in particular the hood, so that a uniform vacuum suction input is applied to the entire sealed space S. It is.

The heater 50 and the vacuum pump 40 are controlled by a controller 70, in particular a microprocessor to which a series of processes are input.

In addition, after the vacuum packaging bag B is laminated by the heater 50, air is introduced into the sealed space S on which the vacuum suction input is applied, thereby easily opening the base 10 and the hood 20. It is preferable to further include a vacuum release means to achieve.

 The vacuum releasing means 60 shown in FIGS. 1B and 3 includes an air inlet 63 formed through the hood 20, and the vacuum pump 40 and the nozzle 41 as controlled by a controller. Or a three-way valve 61 for communicating the air inlet hole 63 and the nozzle 41.

However, the vacuum release means may be employed in the form of a button to open the air inlet when simply pressurized.

In addition, the vacuum packaging machine according to the present invention is based on a separate rotating shaft provided in the side portion of the heater 50 is arranged and the portion provided with the sealed space forming member 30 in order to further extend the independent use range of the heater The idea was to be rotated to open.

That is, the base 10 and the hood 20 are divided into first and second powders 10A, 10B and 20A and 20B, respectively, which is the middle of the vacuum packaging bag in which the contents are already sealed and the inlet is sealed. This is useful when you want to partially heat seal.

In more detail, as shown in FIG. 4B, the contents are driven to the edge so that the contents are not caught between the sheets constituting the packaging bag in the vacuum packaging bag B containing the contents and the inlet is sealed, and then the packaging bag (B). In the case of forming the suture portion B2 in the form of a crisscross, a portion of the base 10 and the hood 20 in which the member 30 for forming the closed space S is arranged is the vacuum packaging bag B3. Due to the protrusion (B3) the contents of the) is in contact with the hood and the base is in contact, that is, the heater 50 and the pressure member 51 is prevented from contacting.

Therefore, as shown in Figs. 2A, 2B, and 2C, the base 10 and the hood 20 are divided into first and second powders 10A, 10B and 20A and 20B, and each powder is rotated in a rotational axis. In particular, when the hinge shafts H3 and H2 arranged under the hinges H1 and H2 can be unfolded back and forth, the problem of interference between the base and the hood due to the sealed space forming member can be solved.

The pivot shaft H3 for spreading the upper and lower first and second powders is connected to a bracket H3b connected to the powders 10A and 10B of the base 10 on the hinge H1 and H2 sides. Although it is made of a pin (H3a), like the hinge (H1) (H2), each powder can be deformed in the form of spreading up and down, and also the arrangement position of the rotation shaft to the left side opposite the hinge (H1) (H2) It can be modified.

The contact surfaces of the first and second powder 10A, 10B (20A, 20B) is preferably provided with a member for fixing the combined state of the powder, the fixing member shown is a magnet (11a) (11b) It is. Alternatively, various members can be employed including fastening members in the form of clips.

The connection of the power and control relationship for the vacuum pump 40 and the heater 50, in particular the interconnection of the base and the hood, must naturally continue through the hinge H1 (H2) arrangement.

In addition, as shown in Figure 2b, the vacuum packaging machine, in particular the hood 20 is equipped with a cutter (C) it is convenient to cut the packaging bag before or after vacuum packaging. The cutter can be replaced with small scissors.

The cutter (C) is mounted to the mounting portion (C4) of the hood in a sliding manner, in order to prevent the human body such as fingers from being cut off, the blade (C1) is masked so as not to be directly exposed by the two projections (C2a, C2b). In addition, the blade (C1) is arranged in an inclined form can be prevented from occurring a problem in the cutting force due to increased friction with the packaging bag to be cut, and also has a non-slip projection (C3).

Referring to the operation relationship of the vacuum packaging machine of the present invention described above with reference to the control unit 70 as follows.

First, in a typical vacuum packaging machine, as shown in FIGS. 1B and 3, the mode selection button 71 provided on the hood 20 in a state where the upper and lower powders 10A, 10B and 20A and 20B are coupled to each other.

Subsequently, the other end of the vacuum packaging bag inlet is filled with the contents in a sealed vacuum packaging bag, and the inlet is placed on the packing member 35 of the base 10 where the sealed space forming member 30 is to be located.

At this time, in order to position the inlet of the packaging bag exactly in the middle of the closed space (S) may be formed in the middle of the lower packing member 35, the stopper 37 arranged in a left and right row.

Subsequently, the vacuum pump 40 is automatically closed by the microprocessor of the control unit 70 by closing the hood 20 and by the operation of a switch (not shown). The suction force of the pump extends to the nozzle 41 through the connecting pipe 43 and the vacuum suction input is applied to the sealed space S, and the air inside the bag is discharged to the outside air through the inlet B1 of the bag B. do.

At this time, the concave portion 31, which is a forming member 30 for the sealed space out of the imaginary plane formed by the contact surface of the base and the hood engaged is arranged in the hood 20, the pump 40 and Since the connected nozzle 41 is also arranged inside the recess 31 of the hood 20, when the contents contained in the vacuum packaging bag contain liquid, the liquid contents are introduced into the pump through the nozzle by the suction force of the pump. The problem of pump contamination, malfunction, or failure can be prevented because the liquid contents do not enter the nozzle by gravity and remain on the bottom, that is, the lower packing member 35 arranged on the base 10 without a separate filter member. Can be.

Subsequently, when the air is discharged to some extent within the packaging bag, the heater 50 is operated through the pressure sensing of the closed space S by a sensor.

When the sealing of the inlet rear of the vacuum bag (B) by the heater 50 is completed by the reference time measurement or the temperature sensing, a connecting pipe connecting the pump 40 and the heater 50 by the command of the controller. The three-way valve 61, which has opened the pipe of 43, closes the pump-side pipe by the operation of the solenoid and connects the air inlet 63 formed in the hood 20 to the nozzle 41 and the nozzle 41. Will open.

Accordingly, the outside air flows into the sealed space S to release the vacuum of the sealed space, thereby completing the vacuum packing.

In addition, the mode selection button 71 is placed in the heater mode, and the vacuum packaging bag to be heat-sealed is arranged at the heater 50 position, the base and the hinge are engaged, and the heater operation switch 73 is operated to seal. Seal completion is controlled by time or temperature.

If as shown in Figure 4b, when the contents are already vacuum packed in the vacuum packaging bag (B) to divide the packaging bag and resealing, the contents in the form to be divided and sealed to drive the contents between the sheets forming the packaging bag Do not intervene.

Subsequently, the first and second powders 10A and 10B of the base 10 and the first and second powders 20A and 20B of the hood 20 are opened at least 90 degrees back and forth from the pivot shaft H3. Due to the second powders 10B and 20B in which the closed space forming member is located, the vacuum packaging machine is not balanced and does not fall down without interrupting the sealing operation.

Subsequently, each of the first powders 10A and 20A of the base and the hood is engaged with the hinges H1 and H2 as a starting point, and the operation switch 73 is pressed to seal and form a seal at a desired portion.

The method of sealing the vacuum packaging bag using the vacuum packaging machine of the present invention described above may be carried out in various ways.

For example, after sealing the end opposite to the inlet of the vacuum packaging bag (B), the contents are introduced into the inlet and the middle portion of the vacuum packaging bag is sealed in a straight line corresponding to the end sealing form. The term “correspondence” is a concept here meaning that the end seal and the seal do not cross when they extend.

Then, the contents are introduced again through the inlet, and the process of sealing the inlet part or sealing the middle part is repeated.

In such a linear intersealing process, a crossover intermediate sealing process may be performed in parallel. The expression “cross” here is a concept that refers to all intersections at various angles, including crosswise crosses when extending the seal.

Alternatively, after sealing the end opposite the inlet of the vacuum bag, the contents are introduced into the inlet, and the middle portion of the vacuum bag is subjected to a straight middle seal or the inlet seal in a form corresponding to that of the end seal. The portion may be a straight middle seal or a cross-sealed intermediate seal in a form corresponding to the end sealing form, or a straight middle seal and cross-sealed intermediate seal may proceed in parallel.

As described above, the vacuum packaging machine equipped with the side hinge according to the present invention adopts the “side hinge” arrangement, and separates the portion for the heater and the portion for the sealing space forming member separately from the base and the hood. By expanding the coaxial point, the application range of the vacuum packaging machine was expanded by allowing the heater to be used independently of the vacuum bag.

In addition, the present invention is arranged with a plurality of nozzles at a predetermined interval in the sealed space so that the vacuum suction input is uniform throughout the sealed space, the liquid contents are sucked into the vacuum pump through the nozzle during the vacuum of the packaging bag to contaminate the pump, In order to prevent the cause, the enclosed space and the nozzle are arranged only in the hood to prevent the liquid contents from flowing into the nozzle by gravity.

Furthermore, the present invention can use a vacuum packaging machine having side hinges to seal multiple vacuum packaging bags in various forms.

In the above description, a specific well-known technology related to the operation and control relationship of the vacuum packaging machine is omitted, but those skilled in the art will be able to speculate or infer this.
