Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows an overview of the vacuum packaging device 10 of the embodiment. FIG. 1 shows a front view, a plan view, a right side view, and a perspective view of the vacuum packaging device 10. In the vacuum packaging device 10, the main body portion 20 and the lid portion 30 are attached so as to be openable and closable by a hinge mechanism 40. An operation panel 50 is provided on the front surface of the vacuum packaging device 10. On the upper surface of the main body 20, a chamber 60 for vacuum-packing a plastic bag for vacuum-packing is provided.

On the upper surface of the main body 20 on the front side, a heater for sealing that closes the packaged object input port of the plastic bag after vacuum processing in order to heat-press and seal the plastic bag for vacuum packaging (not shown). A closed block 70 is provided.

The chamber 60 is a pressure-resistant container composed of a main body portion 20 on which a plastic bag A (see FIG. 4) can be placed on the upper surface, and a lid portion 30 that closes the main body portion 20 from above. The lid portion 30 can be rotated in the vertical direction by the hinge mechanism 40, and a sealing material (not shown) is provided at the contact portion between the lid portion 30 and the main body portion 20 to maintain the airtightness in the chamber 60. It is configured to be able to. Further, a suction port is formed in the main body 20, and when the vacuum pump is operated, the air in the chamber 60 is sucked from the suction port, and the inside of the chamber 60 is depressurized.

As shown in FIG. 2, the closed block 70 includes a lower closed block (operating block) 70a provided on the main body 20 side in a state of being able to move up and down, and an upper closed block 70a fixed to the lower surface side of the lid portion 30. The forming block 70b (fixed block) is provided so as to face each other. When the plastic bag A is vacuum-packed, the packaged object input port of the plastic bag A for vacuum packaging is placed on the lower closed block 70a provided on the upper surface of the main body 20, and the packaged object is stored. The bag portion is placed on the table 60a of the chamber 60.

In the present invention, in order to make the plastic bag A for vacuum packaging reusable, the packaged object input port is bonded and sealed with a sealing clip 80. Then, as shown in FIG. 2, the lower clip 80a ( convex side) of the sealing clip 80 is attached to the lower closed block 70a, and the upper clip 80b ( concave side) of the sealing clip 80 is attached to the upper closing block 70b. Install. The upper clip 80b ( concave side) may be attached to the lower closed block 70a, and the lower clip 80b ( convex side) may be attached to the upper closed block 70b.

FIG. 4A shows an example of a sealing clip 80 composed of a lower clip 80a and a lower clip 80b. FIG. 4B shows a state in which the packaged object input port of the plastic bag A is closed by the sealing clip 80.

Returning to FIG. 2, the facing surfaces of the lower closed block 70a and the upper closed block 70b may have the same width. When the plastic bag A is set in the lower closed block 70a in the chamber 60, the inside of the chamber 60 is depressurized by the vacuum pump 100 and the air inside the plastic bag A is degassed, the lower closed block 70a is set. , It rises upward by driving the closing cylinder 110.

When the packaged object input port of the plastic bag A for vacuum packaging is sealed by using the sealing clip 80, the lower clip 80a is attached to the lower closing block 70a and the upper closing block 70b is attached as shown in FIG. When the lower closed block 70a is pushed up to the upper closed block 70b on the fixed side with the upper clip 70b attached, the lower clip 80a and the upper clip 80b are combined and vacuum-sealed.

Further, when the packaged object input port is heat-bonded without using the sealing clip 80, the lower closed block is held with the plastic bag sandwiched between the upper closed block 70b and the lower closed block 70a. When the sealing heater arranged on the upper surface of the 70a is energized, the packaged object input port of the plastic bag is heat-bonded in a closed state and vacuum-sealed.

Further, at least on the bag holding surface (upper surface) of the lower closed block 70a, a bag attaching portion made of a gel-like sheet having heat resistance and adhesiveness (for example, a sheet made of silicon rubber) may be provided. Due to the bag attachment part, the zipper part of the plastic bag A placed on the upper surface of the lower closed block 70a and the packaged object input port are displaced, and the plastic bag A in the pinched state is on the lower side of the upper closed block 70b. It is possible to prevent the inconvenience of coming out of the closed block 70a. The bag sticking portion may be arranged at a position deviated from the sealing heater (specifically, the rotation center side of the lid portion 30 with respect to the sealing heater). Further, instead of the gel-like sheet, a re-adhesive tape may be attached to the upper surface of the lower closed block 70a to prevent the zipper portion of the plastic bag A and the packaged object input port from shifting.

In the embodiment using the sealing clip 80, the sealing clip 80 is temporarily fixed to the closed block 70. Therefore, if the adhesive force of the bag attachment portion is not sufficient, the temporary fixing mounting member 90 is used. It may be configured to be fixed.

FIG. 5 is a diagram showing an example of a mounting member 90 for temporary fixing. FIG. 5A shows a lower mounting member 90a (one side) for temporarily fixing a lower clip 80a ( hereinafter, the concave side is shown as an example ) to both ends of the lower closed block 70a in the longitudinal direction. ing. FIG. 5B shows an upper mounting member 90b (the other side) for temporarily fixing the upper clip 80b ( hereinafter, the convex side is shown as an example ) to both ends of the upper closed block 70b in the longitudinal direction. There is.

The mounting members 90a and 90b are composed of a flat portion having a width and a slightly wide width of the closed blocks 70a and 70b, and vanes provided on both sides of the flat portion and slightly curved inward. The closed blocks 70a and 70b are lightly sandwiched from both sides by the elastic force of the vane to temporarily fix the sealing clips 80a and 80b. Therefore, the tip side of the vane has the same or slightly wider width as the width of the closed blocks 70a and 70b, but the width H1 near the center of the vane is slightly narrower than the width H2 of the closed blocks 70a and 70b. Is. That is, the pinching force of the mounting members 90a and 90b is sufficient to be easily taken by the fingertips. That is, the mounting members 90a and 90b have a shape that can be easily removed from the vacuum-packed plastic bag, and the pinching force may be sufficient. Further, the vane portion may have a shape in which spherical protrusions are provided instead of the curved shape.

In the lower mounting member 90a of FIG. 5A, both sides of the lower closed block 70a are sandwiched between the wings from the upper side of the flat surface of the lower clip 80a without recesses so that the lower clip 80a does not move. Temporarily fix to. Further, the upper mounting member 90b in FIG. 5B sandwiches both sides of the upper closed block 70b with wings from the upper side of the flat surface of the upper clip 80b without a convex portion, and does not move the upper clip 80b. Temporarily fix it. In order to improve workability after vacuum packaging, the pinching force of the upper mounting member 90b is weaker than the pinching force of the lower mounting member 90a. As a result, when the lower closed block 70a and the lower clip 80a are both lowered, the upper mounting member 90b is separated from the upper closed block 70b without breaking the connection between the lower clip 80a and the upper clip 80b.

Returning to FIG. 2, the internal configuration of the vacuum packaging device 10 will be described.
The vacuum packaging device 10 includes a control device 200, a vacuum pump 100, and an intake flow path 120 that connects the vacuum pump 100 and the suction port 60b of the chamber 60. A vacuum solenoid valve 130 is provided in the middle of the intake flow path 120 to allow or release communication between the vacuum pump 100 and the chamber 60. Further, a vacuum release solenoid valve 150 is provided between the suction port 60b of the intake flow path 120 and the vacuum solenoid valve 130 via the vacuum open branch flow path 140. The vacuum release solenoid valve 150 is configured so that the inside of the chamber 60 can be returned to the atmospheric pressure (open to the atmosphere) from the depressurized state.

Further, in the inlet closing drive flow path 160 between the closing cylinder 110 for raising and lowering the lower closing block 70a and the vacuum pump 100, an inlet closing solenoid valve 170 composed of a three-way valve is provided. It is provided. The solenoid valve 170 for closing the inlet is used for the operation of allowing and releasing the communication between the closing cylinder 110 and the vacuum pump 100 by controlling the opening and closing of the three connection valves, and the operation of controlling the opening to the atmosphere. To.

Next, the configuration of the control mechanism centering on the control device 200 will be described with reference to FIG. The control device 200 includes a microcomputer (hereinafter referred to as a CPU) 210 that controls the vacuum packaging device 10, an interface circuit 220 that performs input / output processing of each signal, and the like. The interface circuit 220 includes various operation switches such as a power switch 50a provided on the operation panel 50 of the vacuum packaging device 10, a pressure and time setting switch 50b, and a switch 50c for selecting coupling by a sealing clip 80. The signal from is input. Further, signals from the air pressure detection sensor 230 for detecting the air pressure in the chamber 60 and the lid open / close detection sensor 240 for detecting the open / closed state of the lid 30 are input to the interface circuit 220.

Upon receiving a signal from the interface circuit 220, the CPU 210 receives a signal from the interface circuit 220, and via the interface circuit 220, the vacuum pump 100, the vacuum solenoid valve 130, the input port closing solenoid valve 170, the vacuum opening solenoid valve 150, the sealing heater 250, and various notifications. A control signal is output to a notification unit 50d including a buzzer that emits a sound and a display that displays various states. Further, the CPU 210 sets in advance the target value of the atmospheric pressure in the chamber 60 in the vacuum packaging work by the operator inputting and operating the setting switch 50b, and the atmospheric pressure detected by the atmospheric pressure detection sensor 230 reaches the set pressure. Taking this as an opportunity, it is configured to control the operation of the vacuum packaging device 10. In the following description, the description of transmission / reception of the signal via the interface circuit 220 will be omitted, and the operation of only the CPU 210 will be described.

Next, the operation of the embodiment will be described with reference to FIGS. 6 to 9.
FIG. 6 is a flowchart showing a control operation centered on the CPU 210 of the embodiment.
First, the worker turns on the power switch 50a provided on the operation panel 50 of the vacuum packaging device 10 (S10 in FIG. 6). Then, the worker opens the lid portion 30 and sets a plastic bag for vacuum packaging containing the object to be packaged on the table 60a in the chamber 60. At this time, the packaged object input port of the plastic bag A is set in the recess of the lower clip 80a temporarily fixed to the lower closed block 70a. Further, the setting switch 50b of the operation panel 50 is operated to set the target value of the air pressure in the chamber 60 and / or the depressurization time (S20 in FIG. 6).

Here, the sealing is performed by connecting the sealing clips 80. The operator sets the target value of the atmospheric pressure and / or decompression time suitable for the used plastic bag A for vacuum packaging (the decompression time is 20 seconds and the pressure is 1.2 KPa, although it depends on the size and material of the bag). The setting is made using the setting switch 50b of the operation panel 50. Further, the operator presses the selection switch 50c provided on the operation panel 50. The selection switch 50c may be a mechanical switch, or may be a software method for pressing a button displayed on the display of the operation panel 50 with a touch sensor. In short, it suffices to notify the CPU 210 of a signal indicating that the sealing is performed by coupling the sealing clips 80.

As a result, the CPU 210 of the control device 200 is notified that the sealing is performed by coupling the sealing clip 80 (Yes in S30 in FIG. 6). Upon receiving the pressing signal of the selection switch 50c, the CPU 210 cuts off the energization path of the seal heater 250, for example, and sets the seal heater 250 so that it does not operate. The operator confirms that the packaged object input port of the plastic bag A is set in the recess of the lower clip 80a, closes the lid portion 30, and presses a start button (not shown).

Then, the lid open / close detection sensor 240 detects the closed state of the lid portion 30 and transmits a detection signal to the CPU 210 of the control device 200. Upon receiving the closed state detection signal, the CPU 210 operates the vacuum pump 100 to start depressurization in the chamber 60 (S40 in FIG. 6).

FIG. 6 shows a control state of each solenoid valve by the CPU 210 in this depressurization step. In the figure, a white triangle (Δ) indicates an open state, and a black triangle (▲) indicates a closed state. That is, the CPU 210 opens the vacuum solenoid valve 130 and forms the intake flow path 120 between the vacuum pump 100 and the suction port 60b of the chamber 60 in a passage state. On the other hand, the CPU 210 closes the valve of the vacuum opening solenoid valve 150 and the valve on the vacuum pump side of the inlet closing solenoid valve 170. The CPU 210 operates the vacuum pump 100 at the same time as controlling the opening and closing of each of these solenoid valves to start depressurization. As a result, the air in the chamber 60 is sucked (degassed) from the intake flow path 120, and the inside of the chamber 60 becomes a vacuum state. At this time, the closing cylinder 110 is open to the atmosphere, and the inside of the closing cylinder 110 is not depressurized.

With the depressurization in the chamber 60, the air in the plastic bag A is also degassed and becomes a vacuum state. When the CPU 210 reaches the set target atmospheric pressure and / or the decompression time value (after a predetermined time) at the same time as the depressurization when the depressurization is performed instantaneously in the chamber 60, or when the depressurization requires time. By pushing the lower closed block 70a upward and pressing it against the upper closed block 70b , the lower clip 80a attached to the lower closed block 70a and the upper clip 80b attached to the upper closed block 70b are attached. By combining, the packaged object input port of the plastic bag A on the lower clip 80a is sealed (S50 in FIG. 6).

FIG. 8 shows a control state of each solenoid valve by the CPU 210 in this coupling step. That is, the CPU 210 changes the vacuum solenoid valve 130 from the open state to the closed state, and maintains the vacuum open solenoid valve 150 in the closed state. As a result, the vacuum state in the chamber 60 is maintained as it is. Then, in order to form the inlet closing drive flow path 160 between the closing cylinder 110 and the vacuum pump 100, the CPU 210 is in a state of opening two directions of the inlet closing solenoid valve 170 (the atmosphere side is closed). State).

Since the inlet closed drive flow path 160 is formed, the air in the closing cylinder 110 is degassed by the vacuum pump 100, and the lower closing block 70a connected to the closing cylinder 110 is removed. Push it up . Then, as described above, by pressing the lower closed block 70a against the upper closed block 70b, the packaged object input port of the plastic bag A is closed by the coupling of the sealing clips 80 (80a, 80b).

When the joining step is completed, the CPU 210 opens the chamber 60 to the atmosphere and leaves the notification unit 50d to indicate that the vacuum packaging is completed (for example, sounding a buzzer). The operator opens the lid portion 30 and takes out the vacuum-packed plastic bag (S60 in FIG. 6).

FIG. 9 shows a control state of each solenoid valve by the CPU 210 in this opening step. That is, the CPU 210 maintains the closed state of the vacuum solenoid valve 130 and stops the operation of the vacuum pump 100. On the other hand, the vacuum release solenoid valve 150 is changed from the closed state to the open state. As a result, the air from the vacuum release solenoid valve 150 is guided into the chamber 60, and the inside of the chamber 60 is opened to the atmosphere. At the same time as the vacuum opening solenoid valve 150 is opened, the CPU 210 forms an inlet closing drive flow path 160 between the closing cylinder 110 and the atmosphere, so that the CPU 210 and the atmosphere side valve of the inlet closing solenoid valve 170 are formed. The valve on the closing cylinder 110 side is opened. As a result, the air from the closing solenoid valve 170 for closing the inlet is guided into the closing cylinder 110, and the inside of the closing cylinder 110 is opened to the atmosphere. Therefore, the lower closed block 70a connected to the closing cylinder 110 is lowered to release the gripped state by the upper closed block 70b and the lower closed block 70a. Then, the CPU 210 notifies (for example, sounding a buzzer) that the vacuum packaging is completed from the notification unit 50d. In response to this, the operator opens the lid portion 30 and takes out the plastic bag for which vacuum packaging has been completed (S60 in FIG. 6).

Next, a case where sealing by heat crimping without using the sealing clip 80 will be described. After turning on the power switch 50a, the operator sets the plastic bag containing the packaged object in the chamber 60. The operator sets the target value of the atmospheric pressure suitable for the used plastic bag and / or the depressurization time by using the setting switch 50b of the operation panel 50. When the sealing clip 80 is not used, the selection switch 50c provided on the operation panel 50 is not pressed, so that the CPU 210 recognizes that the heat crimping is performed by using the sealing heater 250 (No in S30 in FIG. 4).

In the plastic bag setting process, with the lid portion 30 open, the bag portion containing the packaged object of the plastic bag is placed on the table 60a of the main body portion 60, and the packaged object input port of the plastic bag is placed. Is placed directly on the lower closed block 70a. After setting the plastic bag, the operator closes the lid 30 and presses a start button (not shown).

The lid open / close detection sensor 240 detects the closed state of the lid portion 30 and transmits a detection signal to the CPU 210. Upon receiving the closed state detection signal, the CPU 210 operates the vacuum pump 100 to start depressurization in the chamber 60 (S70 in FIG. 6). Since the control of each solenoid valve by the CPU 210 at this time is the same as that in FIG. 6, the description thereof is omitted.

With the depressurization in the chamber 60, the air in the plastic bag is also degassed and becomes a vacuum state. When the CPU 210 reaches the set target value of atmospheric pressure and / or the value of the decompression time, the lower closed block 70a is lifted upward and the lower closed block 70a is pressed against the upper closed block 70b (FIG. 6). S80). Next, the CPU 210 lifts the lower closed block 70a upward, and at the same time, energizes the sealing heater 250 and heat-presses the packaged object input port of the plastic bag in a vacuum state in a closed state. Seal (S90 in FIG. 6). Since the control of each solenoid valve by the CPU 210 at this time is the same as that in FIG. 8, the description thereof is omitted.

When the heat crimping step is completed, the inside of the chamber 60 and the inside of the closing cylinder 110 are opened to the atmosphere. Then, the lid portion 30 is opened and the vacuum-packed plastic bag is taken out (S100 in FIG. 6). Since the control of each solenoid valve by the CPU 210 at this time is the same as that in FIG. 9, the description thereof is omitted.

As described above, according to the embodiment, it is possible to provide a vacuum packaging device that binds and seals a plastic bag for vacuum packaging by using a sealing clip. Plastic bags for vacuum packaging can be reused several times if the inside of the packaging is cleaned even after opening the sealed clip (however, those that are heavily soiled and those that cannot be reused due to food are excluded. ), And the packaging bag resources can be used effectively. In addition, when a sealing clip is used, it can be vacuum-sealed without using a sealing heater, so that safety can be improved and power saving can be achieved. When a dedicated vacuum packaging device using a sealing clip is configured, a sealing heater for heating the packaged object input port becomes unnecessary, so that an inexpensive device can be provided.

When the packaged object contains a liquid, the temperature of the liquid may be normal temperature or high temperature. The liquid contained in the packaged object may be a liquid composed of components other than water, for example, edible oil for immersing food, or a liquid other than food (formalin for immersing a biological specimen, etc.). There may be. Further, the temperature of the liquid may be lower than normal temperature.

Further, the vacuum packaging device in each of the above embodiments may be arbitrarily redesigned as long as it does not deviate from the technical features of the present invention. For example, although the structure is such that an upper closed block (fixed block) fixed to the lower surface side of the lid portion is provided, an upper closed block (fixed block) may be provided on the main body portion. In that case, the upper closed block may be provided so as to face the upper side of the lower closed block (operating block). Further, the lower closed block may be a fixed block, and the upper closed block of the operating block (pushing down operation) may be provided so as to face the upper side thereof. Further, the seal heater may be provided on one or both of the lower closed block and the upper closed block.
