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 apparatus 10 of the first embodiment. In FIG. 1, the front view of the vacuum packaging apparatus 10, the top view, the right view, and the perspective view are shown, respectively. In the vacuum packaging device 10, the main body 20 and the lid 30 are attached by a hinge mechanism 40 so as to be freely opened and closed. An operation panel 50 is provided on the front surface of the vacuum packaging apparatus 10. On the upper surface of the main body 20, a chamber 60 is provided in which a storage airtight bag (vacuum packaging bag) is loaded and vacuum-packed.

  The sealed air bag for storage is also called a storage bag with a zip and a storage bag with a zipper. Further, when a vacuum packaging plastic bag (hereinafter simply referred to as a plastic bag) without a zip is used on the upper surface on the front side of the main body 20, a packaging material input port for the vacuum-treated plastic bag is provided. A closing block 70 is provided which contains a closing seal heater (not shown).

  The chamber 60 is a pressure-resistant container composed of a main body portion 20 on which the packaging bag can be placed 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 a 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, the main body portion 20 is provided with a suction port, 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 decompressed.

  As shown in FIG. 2, the closing block 70 includes a lower closing block (working block) 70 a provided so as to be movable up and down on the main body 20 side, and an upper closing fixed to the lower surface side of the lid 30. The building block 70b (fixed block) is provided in a state of facing. When the packaging bag is vacuum-packed, the zipper portion of the storage sealing bag (vacuum packaging bag) A is placed on the lower closed block 70a provided on the upper surface of the main body portion 20, and the packaged item is stored. The bag portion is loaded on the table 60 a of the chamber 60. Even when a vacuum plastic bag is used, an article input port for the plastic bag is placed on the lower closing block 70a.

  The opposing surfaces of the lower closing block 70a and the upper closing block 70b may have the same width. When the packaging bag is set in the chamber 60 and the inside of the packaging bag 60 is depressurized by the vacuum pump 100 and the air inside the packaging bag is deaerated, the lower closing block 70 a is driven by the driving of the closing cylinder 110. Ascend upward. In the case of the storage hermetically sealed bag, the vacuum sealing is completed by pressing the upper closing block 70b and the lower closing block 70a. When using a plastic bag for vacuum, the plastic bag is disposed on the upper surface of the lower closing block 70a with the plastic bag sandwiched between the upper closing block 70b and the lower closing block 70a in the raised state. When the sealing heater is energized, it is heat-pressed and sealed in a state where the packaging material inlet of the plastic bag is closed.

  Moreover, you may provide the bag sticking part comprised by the gel-like sheet | seat (for example, sheet | seat made from a silicon rubber) which has heat resistance and adhesiveness in the bag clamping surface (upper surface) of the lower side closed block 70a at least. Due to the bag adhering portion, the zipper portion of the packaging bag placed on the upper surface of the lower closing block 70a and the input port for the package are shifted, and as a result, the sandwiched packaging bag is closed with the upper closing block 70b. It is possible to prevent inconvenience from coming out between the block 70a. Note that the bag adhering portion may be disposed at a position shifted from the sealing heater (specifically, closer to the center of rotation of the lid 30 than the sealing heater. An adhesive tape may be attached to the upper surface of the lower closed block 70a to prevent the zipper part of the packaging bag and the package input port from being displaced.

Next, the internal configuration of the vacuum packaging apparatus 10 will be described with reference to FIG.
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 60 b of the chamber 60. A vacuum electromagnetic valve 130 that allows or cancels communication between the vacuum pump 100 and the chamber 60 is provided in the intake passage 120. Further, a vacuum release electromagnetic valve 150 is provided between the suction port 60 b of the intake flow channel 120 and the vacuum electromagnetic valve 130 via a vacuum release branch flow channel 140. The vacuum opening electromagnetic valve 150 is opened so that the inside of the chamber 60 can be returned from the reduced pressure state to the atmospheric pressure (can be opened to the atmosphere).

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

  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 50 a provided on the operation panel 50 of the vacuum packaging apparatus 10, a pressure and time setting switch 50 b, and a switch 50 c for selecting a sealed bag for storage. Signal is being input. The interface circuit 220 also receives signals from an atmospheric pressure detection sensor 230 that detects the atmospheric pressure in the chamber 60 and a lid open / close detection sensor 240 that detects the open / closed state of the lid 30.

  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 inlet closing solenoid valve 170, the vacuum release solenoid valve 150, the seal heater 250, various notifications. A control signal is output to the alerting | reporting part 50d which consists of a buzzer which emits a sound, and the display which displays various states. Further, the CPU 210 presets a target value of the atmospheric pressure in the chamber 60 in the vacuum packaging operation by an operator operating the setting switch 50b or the like, and the atmospheric pressure detected by the atmospheric pressure detection sensor 230 has reached the set pressure. With this as an opportunity, the operation of the vacuum packaging device 10 is controlled. In the following description, the transmission / reception of signals via the interface circuit 220 is omitted, and only the operation of the CPU 210 will be described.

Next, the operation of the embodiment will be described with reference to FIGS.
FIG. 4 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 apparatus 10 (S10 in FIG. 4). Then, the worker opens the lid 30 and sets the packaging bag containing the article to be packaged in the chamber 60. Further, the setting switch 50b of the operation panel 50 is operated to set the target value for the atmospheric pressure and / or the pressure reduction time in the chamber 60 (S20 in FIG. 4).

  Here, it is assumed that the storage airtight bag A is used as the packaging bag. The operator can select the appropriate pressure and / or depressurization time target value for the storage airtight bag A used (the depressurization time is 20 seconds and the pressure is 1.2 KPa, depending on the size and material of the bag). The setting is performed using 50 setting switches 50b. The operator presses a selection switch 50c provided on the operation panel 50. Thereby, it is notified to CPU210 of the control apparatus 200 that the airtight bag A for storage was set in the chamber 60 (Yes of S30 of FIG. 4). The selection switch 50c may be a mechanical switch, or may be a software method of pressing a button displayed on the display of the operation panel 50 with a touch sensor. In short, what is necessary is just to notify CPU210 the signal which shows that the airtight bag A for preservation | save was loaded in the chamber.

  Moreover, in the setting process of the airtight bag A for storage, while the lid 30 is opened, the bag portion in which the packaged object of the airtight bag A for storage is stored is placed on the table 60a of the main body 60, The zipper portion is placed in a straight line on the lower closed block 70a. After setting the storage airtight bag A, the operator closes the lid 30 and presses a start button (not shown).

  Then, the lid open / close detection sensor 240 detects the closed state of the lid 30 and transmits a detection signal to the CPU 210 of the control device 200. When the CPU 210 receives the closed state detection signal, the CPU 210 receives the pressing signal of the selection switch 50c, sets the seal heater 250 to an appropriate state, operates the vacuum pump 100, and operates the chamber 60. Start decompressing inside. (S40 in FIG. 4). The appropriate setting of the sealing heater 250 is, for example, a state where the energizing path of the sealing heater 250 is cut and the sealing heater 250 is not present. If the storage airtight bag A is a dedicated machine, the sealing heater 250 may not be provided. Further, there may be a method (current value = 0) in which the sealing heater 250 is provided and the sealing heater 250 is not energized. Further, there may be a method in which a weak current is supplied to the sealing heater 250 when the sealing heater 250 is provided. The weak current is a current that slightly warms the zipper portion of the storage airtight bag A placed on the upper surface of the lower closed block 70a. By slightly warming the zipper part of the airtight storage bag A, the upper and lower zipper parts can be easily combined, and sealing can be performed more easily.

  FIG. 5 shows the control state of each solenoid valve by the CPU 210 in this decompression step. In the figure, the white triangle (Δ) indicates the open state, and the black triangle (▲) indicates the closed state. That is, the CPU 210 opens the vacuum electromagnetic 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 electromagnetic valve 150 and the valve on the vacuum pump side of the inlet closing electromagnetic valve 170. The CPU 210 starts the pressure reduction by operating the vacuum pump 100 simultaneously with the opening / closing control of each electromagnetic valve. Thereby, the air in the chamber 60 is sucked (degassed) from the intake passage 120, and the inside of the chamber 60 is in a vacuum state (S40 in FIG. 4). At this time, the closing cylinder 110 is open to the atmosphere, and the inside of the closing cylinder 110 is not depressurized.

  As the pressure in the chamber 60 is reduced, the air in the storage airtight bag A is also evacuated to a vacuum state. When the pressure in the chamber 60 is instantaneously reduced, the CPU 210 reaches the set target pressure and / or the pressure reduction time value (after a predetermined time) at the same time as the pressure reduction or when time is required for pressure reduction. The lower closing block 70a is lifted upward, and the lower closing block 70a is pressed against the upper closing block 70b, whereby the zipper part of the storage airtight bag A is joined and closed.

  FIG. 6 shows the control state of each solenoid valve by the CPU 210 in this coupling step. That is, the CPU 210 changes the vacuum electromagnetic valve 130 from the open state to the closed state and maintains the closed state of the vacuum release electromagnetic valve 150. Thereby, the vacuum state in the chamber 60 is maintained as it is. The CPU 210 opens the two directions of the inlet closing electromagnetic valve 170 in order to form the inlet closing drive flow path 160 between the closing cylinder 110 and the vacuum pump 100 (the atmosphere side is closed). State).

  By forming the inlet closing drive channel 160, the air in the closing cylinder 110 is deaerated by the vacuum pump 100, and the lower closing block 70 a connected to the closing cylinder 110 is removed. The zipper part of the preservation | save sealing bag A is couple | bonded and closed by lifting up and pressing the lower closing block 70a to the upper closing block 70b (S60 of FIG. 4).

  When the joining step is completed, the CPU 210 opens the chamber 60 to the atmosphere, and notifies the notification unit 50d that the vacuum packaging has been completed (for example, sounds a buzzer). An operator opens the cover part 30 and takes out the airtight sealed storage bag.

  FIG. 7 shows the control state of each solenoid valve by the CPU 210 in this opening process. That is, the CPU 210 maintains the closed state of the vacuum electromagnetic valve 130 and stops the operation of the vacuum pump 100. On the other hand, the vacuum release electromagnetic valve 150 is changed from the closed state to the open state. Thereby, the air from the vacuum release electromagnetic valve 150 is guided into the chamber 60, and the inside of the chamber 60 is opened to the atmosphere. Simultaneously with the opening of the vacuum opening solenoid valve 150, the CPU 210 forms an inlet closing drive channel 160 between the closing cylinder 110 and the atmosphere. The valve on the closing cylinder 110 side is opened. As a result, the air from the inlet closing solenoid valve 170 is guided into the closing cylinder 110 and the inside of the closing cylinder 110 is opened to the atmosphere. Therefore, the lower closing block 70a connected to the closing cylinder 110 is lowered, and the gripping state by the upper closing block 70b and the lower closing block 70a is released (S60 in FIG. 4). Then, the CPU 210 notifies (for example, sounds a buzzer) that the vacuum packaging is completed from the notification unit 50d. In response to this, the operator opens the lid 30 and takes out the airtight bag for storage that has been vacuum-packed.

  Next, it is assumed that a plastic bag is used as the vacuum packaging bag. An operator sets the plastic bag which accommodated the to-be-packaged item in the chamber 60, after turning on the power switch 50a. The operator sets the pressure and / or pressure reduction time target value suitable for the plastic bag used (the pressure reduction time is 20 seconds and the pressure is 1.2 KPa depending on the size and material of the bag) on the operation panel 50. Setting is performed using the switch 50b. When a plastic bag is used, the selection switch 50c provided on the operation panel 50 is not pressed, so the CPU 210 recognizes that a plastic bag requiring thermocompression bonding is loaded in the chamber 60 (No in S30 in FIG. 4).

  In the plastic bag setting process, with the lid 30 opened, the bag portion in which the plastic bag package is stored is placed on the table 60a of the main body 60, and the plastic bag package input port Is placed on the lower closing 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 30 and transmits a detection signal to the CPU 210. When the CPU 210 receives the detection signal of the closed state, the CPU 210 operates the vacuum pump 100 to start depressurization in the chamber 60 (S70 in FIG. 4). Since the control of each solenoid valve by the CPU 210 at this time is the same as in FIG. 5, the description thereof is omitted.

  As the pressure in the chamber 60 is reduced, the air in the plastic bag is also evacuated to a vacuum state. When the CPU 210 reaches the set atmospheric pressure and / or pressure reduction time, the CPU 210 lifts the lower closing block 70a upward and presses the lower closing block 70a against the upper closing block 70b (FIG. 4). S80). Next, the CPU 210 lifts the lower closed block 70a upward, and at the same time energizes the sealing heater 250, and performs heat-pressure bonding in a state where the packaging material inlet of the vacuum plastic bag is closed. Sealing is performed (S90 in FIG. 4). Since the control of each solenoid valve by the CPU 210 at this time is the same as in FIG. 6, the description thereof is omitted.

  When the thermocompression bonding process is completed, the inside of the chamber 60 and the inside of the closing cylinder 110 are opened to the atmosphere. And the cover part 30 is opened and the plastic bag vacuum-packed is taken out (S100 of FIG. 4). Since the control of each solenoid valve by the CPU 210 at this time is the same as in FIG. 7, the description thereof is omitted.

  As described above, according to the embodiment, it is possible to provide a vacuum packaging device that uses the storage sealed bag as a vacuum packaging bag. The airtight bag for storage can be reused as long as the inside of the package is cleaned even after the zipper is opened (excluding items that are heavily soiled or cannot be reused due to food). , Packaging bag resources can be used effectively. In addition, when a storage airtight bag is used, it can be vacuum-sealed without using a sealing heater, so that safety can be improved and power saving can be achieved. In the case of configuring a dedicated vacuum packaging apparatus that uses the storage airtight bag as a vacuum packaging bag, a sealing heater for heating the package input port is not required, so that an inexpensive apparatus can be provided.

Next, the vacuum packaging apparatus of 2nd Embodiment is shown with reference to FIG. 8 thru | or FIG.
In the second embodiment, a packaging bag with a check valve is used as the packaging bag. As shown in FIG. 8, the check valve packaging bag 300 includes check valves 310 and 320 that flow in the degassing direction only inside the packing bag at both end portions of one side surface. When deaerated, it is a packaging bag in which air does not enter from the outside due to the action of the check valve. In addition, on the opposite side surface of the check valves 310 and 320, an opening slider 330 and a chuck 340 that constitute a package entry port are provided. In the second embodiment, the vacuum packaging device is used to evacuate the air from the packaging bag with a check valve into which the article to be packaged is charged, and then the chuck 340 is slid along the slider 330 to be opened. The packaged item can be taken out. When a dedicated vacuum packaging device that uses the check bag packaging bag as a vacuum packaging bag is configured, the upper and lower closing blocks, the closing cylinder, and the seal heater for heating the package input port Is unnecessary.

  FIG. 9 is a block diagram showing the configuration of the control mechanism in the second embodiment. In FIG. 9, the selection switch 50e which selects using the packaging bag with a check valve as a vacuum packaging bag is provided. Other configurations are the same as those in FIG. 3, and the description thereof is omitted. The selection switch 50e may be a mechanical switch or may be a software method of pressing a button displayed on the display of the operation panel 50 with a touch sensor. In short, what is necessary is just to notify CPU210 the signal which shows that the packaging bag with a non-return valve was loaded in the chamber.

  FIG. 10 is a flowchart showing a control operation centered on the CPU 210 of the second embodiment. First, the worker turns on the power switch 50a provided on the operation panel 50 of the vacuum packaging apparatus 10 (S150 in FIG. 10). Then, the worker opens the lid portion 30 and sets a packaging bag with a check valve into which an article to be packaged is placed in the chamber 60.

  In addition, the operator operates the setting switch 50b of the operation panel 50, and the pressure value suitable for the packaging bag with a check valve and / or the target value of the pressure reduction time (which varies depending on the size and material of the bag, 20 seconds, the pressure is set to 1.2 KPa) is set using the setting switch 50b of the operation panel 50 (S152 in FIG. 10). The worker presses a selection switch 50e provided on the operation panel 50. Thereby, it is notified to CPU210 of the control apparatus 200 that the packaging bag B with a check valve was set in the chamber 60 (Yes of S154 of FIG. 10). In response to the pressing signal of the selection switch 50e, the CPU 210 sets the sealing heater 250 so as not to operate, for example, by cutting the energization path of the sealing heater 250 that is not used in the packaging bag B with the check valve (FIG. 10). S156).

  Moreover, in the setting process of the packaging bag B with a check valve, the operation is only to place the packaging bag B with a check valve on the table 60a of the main body 60 with the lid 30 opened. Note that the chuck of the packaging bag B with the check valve is closed. After the operator sets the packaging bag B with the check valve, the operator closes the lid 30 and presses a start button (not shown).

  Then, the lid open / close detection sensor 240 detects the closed state of the lid 30 and transmits a detection signal to the CPU 210 of the control device 200. When the CPU 210 receives the closed state detection signal, the CPU 210 operates the vacuum pump 100 to start depressurization in the chamber 60.

  FIG. 11 shows the control state of each solenoid valve by the CPU 210 in this decompression step. That is, the CPU 210 opens the vacuum electromagnetic 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 electromagnetic valve 150 and the valve on the vacuum pump side of the inlet closing electromagnetic valve 170. The CPU 210 starts the pressure reduction by operating the vacuum pump 100 simultaneously with the opening / closing control of each electromagnetic valve. Thereby, the air in the chamber 60 is sucked (degassed) from the intake passage 120, and the inside of the chamber 60 is in a vacuum state. Thereby, the packaging bag B with a check valve swells due to the differential pressure between the pressure inside the packaging bag B with a check valve and the pressure in the chamber 60, and the air in the packaging bag is degassed from the check valve ( S158 in FIG.

  When the air in the packaging bag B with check valve is exhausted to the outside, the inside of the chamber 60 is opened to the atmosphere, the lid 30 is opened, and the vacuum sealed packaging storage bag is taken out.

  FIG. 12 shows the control state of each solenoid valve by the CPU 210 in this opening process. That is, the CPU 210 maintains the closed state of the vacuum electromagnetic valve 130 and stops the operation of the vacuum pump 100. On the other hand, the vacuum release electromagnetic valve 150 is changed from the closed state to the open state. Thereby, the air from the vacuum release electromagnetic valve 150 is guided into the chamber 60, and the inside of the chamber 60 is opened to the atmosphere. And an operator opens the cover part 30, and takes out the packaging bag B with a non-return valve which completed vacuum packaging (S160 of FIG. 10).

  As described above, according to the second embodiment, it is possible to provide a vacuum packaging device that uses a packaging bag with a check valve as a vacuum packaging bag. A packaging bag with a check valve can be reused only a few times if the inside of the packaging is washed clean even after the zipper is opened (excluding items that are heavily soiled or cannot be reused due to food) ) And packaging bag resources can be used effectively. Further, when a packaging bag with a check valve is used, since it can be vacuum-sealed without using a sealing heater, safety can be improved and power saving can be achieved. When configuring a dedicated vacuum packaging device that uses a packaging bag with a check valve as a vacuum packaging bag, the upper and lower closing blocks, the closing cylinder, and the sealing heater for heating the package entry port are not required. Therefore, an inexpensive device can be provided.

  Here, although 1st Embodiment and 2nd Embodiment were demonstrated separately, you may provide the vacuum packaging apparatus which can control both 1st Embodiment and 2nd Embodiment.

  In addition, when the packaged product contains a liquid, the temperature of the liquid may be a normal temperature or a high temperature. The liquid contained in the package may be a liquid composed of components other than water, for example, an edible oil in which food is soaked, or a liquid other than food (formalin in which a biological specimen is immersed). There may be. Furthermore, the temperature of the liquid may be room temperature or lower.

  In addition, the vacuum packaging device in each of the above embodiments may be arbitrarily changed in design without departing from the technical features of the present invention. For example, in the first embodiment, a double zipper is provided at the package entry port of the packaging bag, the first zipper is closed by the vacuum packaging device, and the packaging is completed. May be configured to be closed to further improve the sealing performance of the packaging bag. Moreover, although it was set as the structure which provides the upper closed block (fixed block) fixed to the lower surface side of the cover part, you may provide an upper closed block (fixed block) in a main-body part. In that case, an upper closing block may be provided so as to face the upper side of the lower closing block (operation block). Further, the lower closing block may be a fixed block, and the upper closing block of the operation block (pressing operation) may be provided so as to face the upper side. The sealing heater may be provided in one or both of the lower closing block and the upper closing block.
