Description

Technical Field

[0001] Embodiments of the present invention relate to a deep-digging type vacuum packaging machine and a vacuum packaging machine.

Background Art

[0002] Vacuum packaging is a packaging method in which air is evacuated from a packaging bag containing an object to be packaged and then sealed. Vacuum packaging can prevent the deterioration of the contents and is widely used in fields such as the food industry and industry.

[0003] In such a vacuum packaging machine, a structure having a flat placement surface for placing a vacuum packaging bag in the chamber is common. On the other hand, when handling an object to be packaged containing liquid, with a flat placement surface, especially when vacuum-packaging an object to be packaged containing warm liquid, there is a risk that the internal liquid will spill when evacuating the air, so it is necessary to set it in a shape that does not cause liquid leakage and then perform vacuum packaging. Therefore, the workability was poor.

[0004] As another example of a vacuum packaging machine, there is a deep-digging type vacuum packaging machine for accommodating an object to be packaged (for example, Patent Document 1). However, with regard to the deep-digging type vacuum packaging machine, its development has not been advanced thereafter, and there has been no commercialized product.

[Modes for carrying out the invention]

[0009] Hereinafter, a deep-digging type vacuum packaging machine according to an embodiment will be described with reference to the drawings. In this specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

[0010] <First Embodiment> (Configuration of Deep-Digging Type Vacuum Packaging Machine) FIG. 1 is a cross-sectional view seen from the right side of the deep-digging type vacuum packaging machine with the lid portion forming the chamber closed. FIG. 2 is a cross-sectional view seen from the right side of the deep-digging type vacuum packaging machine with the lid portion open. The deep-digging type vacuum packaging machine 10 has a box-shaped housing. For example, the inner dimensions of the chamber 100 are 473 mm in width, 579 mm in depth, 153 mm in height (flat specification), and 373 mm in height (deep-digging specification), and the seal effective dimension is, for example, 420 mm. The deep-digging type vacuum packaging machine 10 is roughly composed of a main body portion 20 and a lid portion 30 that forms the chamber 100. The lid portion 30 is attached to the main body portion 20 so as to be openable and closable by a hinge mechanism portion 40 provided at the upper rear portion of the main body portion 20.

[0011] The main body portion 20 is provided with an operation panel 210 on the front surface, and a deep-digging placement portion 220 is provided in front of the main body portion 20 at the rear. The deep-digging placement portion 220 is a container in the shape of a box with an open upper portion (a five-sided box). A flat placement portion 230 is provided behind the deep-digging placement portion 220. The bottom surface of the chamber 100 is designed to be several centimeters lower than the outer peripheral portion of the main body portion 20, enhancing the adhesion between the outer peripheral edge 100a of the main body portion 20 and the lid portion 30.

[0012] An opening closing plate 240 can be attached to the opening of the deep-digging placement portion 220. In the state where the opening closing plate 240 is installed, since it is at the same height as the flat placement portion 230, the entire bottom surface of the chamber 100 can form a flat placement surface. Therefore, as shown in FIG. 1, the upper surface of the main body portion 20 that forms the bottom surface of the chamber 100 integrally forms each part of the lower seal block 270 attachment portion in the front, the deep-digging placement portion 220 behind it, and the flat placement portion 230 behind it, so that assembly is easy.

[0013] Moreover, the deep-drawing type vacuum packaging machine 10 of the embodiment can be selectively used in accordance with the application, including a first vacuum packaging mode in which the bag to be packaged is placed on the deep-drawing placement portion 220 for vacuum packaging, and a second vacuum packaging mode in which the bag to be packaged is placed on a flat placement surface formed by the placement portion 230 and the opening / closing plate 240 for vacuum packaging. Thus, two different vacuum packages can be produced using a single machine.

[0014] A vacuum pump 250 is provided below the flat placement portion 230. The vacuum pump 250 serves as a power source for operations such as evacuating the inside of the chamber 100 or opening it to atmospheric pressure via a group 250a of various solenoid valves (vacuum valve, soft vacuum valve, open valve, soft open valve, nano valve, seal valve), and for raising and lowering the lower seal block 270. A hole 255 for evacuating the chamber 100 with the vacuum pump 250 is provided behind the chamber 100. A vacuum state can be formed by evacuating the air inside the chamber 100 through the hole 255.

[0015] In addition, a gas supply device 260 for supplying gas, for example, to create a non-crushable package, is provided between the operation panel 210 and the deep-drawing placement portion 220. The gas supply device 260 is connected to the lower seal block 270 inside the chamber 100 via a gas valve (not shown). The gas supplied from the gas supply device 260 is an inert gas such as nitrogen gas or carbon gas.

[0016] A lower seal block 270 is provided on the front side of the bottom surface of the chamber 100. Opposite to this lower seal block 270, an upper seal block 300 is fixedly attached to the front inner side of the lid 30. When sealing the opening of a vacuum-sealed packaged bag, the lower seal block 270 is pushed up toward the upper seal block 300 by a piston 280 controlled by a vacuum pump 250. Then, a heater wire attached to the surface of the lower seal block 270 on which the packaged bag is placed is energized to melt and seal the opening of the packaged bag. Once sealing is complete, the pushing mechanism of the piston 280 is released, and the lower seal block 270 returns to its original position.

[0017] An expansion detection mechanism 310 is attached to the upper seal block 300. The expansion detection mechanism 310 can detect the expansion of the packaged bag when the bag expands due to vacuuming in the chamber 100, by causing the tip of the lower arm 320 to separate from a magnet (not shown) attached to the inside of the lower seal block 270. The expansion detection mechanism 310 is used during the vacuum operation of the hot pack, which will be described later.

[0018] At least one gas nozzle 290 (multiple gas nozzles in the figure) is attached to the lower seal block 270 (see Figure 6 for details). The gas supplied from the gas supply device 260 passes through the inside of the lower seal block 270 and can be sealed into the packaged bag from the multiple gas nozzles 290. A winding 292 is attached to the gas nozzle 290 that can grip the lower side of the opening of the packaged bag (see Figure 7 for details). An inclined plate 275 is attached to the rear of the lower seal block 270 to guide the packaged bag onto the mounting surface.

[0019] Furthermore, a support column 295 for gripping the upper part of the opening of the packaged bag is attached in front of the lower seal block 270. On the other hand, a retaining block 330 is attached in front of the upper seal block 300. When the upper opening of the packaged bag is placed on the support column 295 and the lid 30 is closed, the retaining block 330 is pressed against the support column 295, setting (gripping) the upper opening of the packaged bag so that it does not move. Since the opening of the packaged bag is set (gripped) so that it does not move by the winding wire 292 and the retaining block 330, it is easy to inject gas from the gas nozzle 290 into the packaged bag.

[0020] The space in the deep recess mounting section 220 can accommodate filling members 350 depending on the application. The filling members 350 are smaller than the bottom shape of the deep recess mounting section 220, and multiple members with the same length and width are prepared (for example, 9 layers). The heights of the filling members 350 do not need to be different. The method of using the filling members 350 is described in detail in Figure 8.

[0021] Figures 3 and 4 show a partial cross-sectional view of the bottom surface of the chamber 100 and illustrate the gap shape of the deep recess mounting section 220. The deep recess mounting section 220 has, for example, a width of 420 mm, a depth of 220 mm, and a depth of 110 mm. The opening closing plate 240 that closes the opening of the deep recess mounting section 220 is removable. When the opening closing plate 240 is attached to the opening of the deep recess mounting section 220, the opening closing plate 240 becomes the same height as the flat mounting section 230. As shown in Figure 4, the distances between the entrance side of the deep recess mounting section 220 and the opening closing plate 240 are L1 = 7.00 mm and L2 = 6.64 mm.

[0022] The opening closure plate 240 not only forms a flat mounting surface but also serves to hold down the packaged bag. For example, when vacuum packing items containing hot liquids, such as curry, beef tongue stew, or stuffed cabbage rolls (referred to as hot packing), reducing the pressure inside the chamber 100 may cause the liquid inside to boil and leak out. Therefore, as shown in Figure 5, when the above hot pack is manufactured, attaching the opening closing plate 240 acts as a member that holds the packaged bag in place. This prevents the liquid inside the packaged bag from overflowing from the opening.

[0023] Figure 6 shows the shape of the gas nozzle 290 attached to the lower seal block 270. Figure 7 shows the installation state of one gas nozzle 290. As shown in Figures 3 and 6, a gas nozzle 290 is attached to the lower seal block 270. The gas supplied from the gas supply device 260 shown in Figure 1 can be sealed into the packaged bag through the gas nozzle 290 via the gas common pipe 299 and the inside of the lower seal block 270.

[0024] As shown in Figures 6 and 7(a), a wire winding 292 that clamps the lower part of the opening of the packaged bag is attached to the front side of the lower seal block 270 below the gas nozzle 290. Then, as shown in Figure 7(b), the lower side of the packaged bag is gripped by sandwiching it between the gas nozzle 290 and the winding wire 292. On the other hand, as shown in Figure 1, the upper side of the opening of the packaged bag is gripped by the support column 295 and the pressing block 330. This allows gas to be sealed into the packaged bag from the gas nozzle 290. By sealing gas when vacuum packing soft items (e.g., soba or udon noodles) or fragile items (e.g., potato chips and other snacks), it is possible to create a pack that will not be crushed.

[0025] Figure 8 shows an example of the installation of a filling member housed in the deep recess mounting section 220, where (a) shows an example of its use as a member for adjusting the height of the deep recess mounting section 220, and (b) shows an example of its use as a member for reducing the volume of the deep recess mounting section 220. As shown in Figure 8(a), in the first vacuum packing mode, if the bag to be packaged 400 to be set in the deep recessed mounting section 220 is smaller than the depth of the deep recessed mounting section 220, the height adjustment within the deep recessed mounting section 220 is used according to the size of the bag to be packaged 400. In Figure 8(a), one layer of filling member 350a is housed in the deep recessed mounting section 220, illustrating the height adjustment of a small bag to be packaged 400 (according to the number of layers). As shown in Figure 8(b), in the second vacuum packing mode, in order to minimize the volume of the unused deep recess mounting section 220, the shape is shown with filling material 350b equivalent to the height of the deep recess mounting section 220 (for example, in 9 layers). Because the volume of the unused deep recess mounting section 220 is reduced by the 9 layers of filling material 350b, the amount of air in the chamber 100 is reduced. Therefore, the time required for the vacuuming (depressurization) operation in the second vacuum packing mode can be shortened.

[0026] (Vacuum packaging using a deep-hole vacuum packaging machine) Next, we will explain how to produce vacuum packs using the deep-hole type vacuum packaging machine 10. Figures 9 to 11 show the process of producing a vacuum pack in the first vacuum pack mode using the deep mounting section 220. Figure 9 shows the state in which a bag to be packaged is set in the deep-hole mounting section of a deep-hole vacuum packaging machine with the lid open in the first vacuum pack mode. Figure 10 shows the state with the packaging bag set in the deep recessed mounting section of the first vacuum packing mode, and the lid opened for vacuum packing. Figure 11 shows the state in which the packaging bag is set in the deep recessed mounting section of the first vacuum packing mode, the pressure inside the chamber 100 is reduced, and the opening of the degassed packaging bag is sealed. Furthermore, in order to manufacture various vacuum packs in the first vacuum pack mode, the operating conditions according to the type of bag to be packaged and the contents of the packaged items are pre-set from the control panel 210.

[0027] First, as shown in Figure 9, with the lid 30 open, the packaging bag 400 containing the items to be packaged is set in the deep recessed mounting section 220. At this time, the leading edge opening of the packaging bag 400 is set on the lower seal block 270. Also, depending on the items to be packaged, the gas nozzle 290 is inserted and set into the opening of the packaging bag 400.

[0028] Next, as shown in Figure 10, when the lid 30 is closed, the vacuum pump 250 is activated to remove the air from inside the chamber 100 through the holes 255. The opening closing plate 240 is attached to the opening of the deep recessed mounting section 220 depending on the item being packaged. When the air inside the chamber 100 is removed through the holes 255 for a set time (or until the set pressure is reduced), the air inside the packaging bag 400 is also removed at the same time, and a vacuum pack is formed.

[0029] Next, as shown in Figure 11, once the air inside the packaged bag 400 is removed, the piston 280 is activated to push up the lower seal block 270, causing the opening of the packaged bag 400 to be sandwiched between the lower seal block 270 and the upper seal block 300. Then, the heater wire provided in the lower seal block 270 is energized to melt and seal the opening of the vacuum-packed packaged bag 400. Once the production of the vacuum pack is complete, the chamber 100 is opened to the atmosphere and the lid 30 is opened to remove the vacuum-packed packaged bag 400. This operation can be repeated to produce the same vacuum pack.

[0030] Figures 12 to 14 show the manufacturing process of a vacuum pack in the second vacuum pack mode using a flat mounting section. Figure 12 shows the state in which a bag to be packaged is set on the flat mounting surface of a deep-hole type vacuum packaging machine with the lid open in the second vacuum packing mode. Figure 13 shows the second vacuum pack mode with the packaging bag set on the flat placement area and the lid opened for vacuum packing. Figure 14 shows the state in which the packaging bag is set on the flat mounting surface of the second vacuum pack mode, the pressure inside the chamber 100 is reduced, and the opening of the degassed packaging bag is sealed. Furthermore, in order to manufacture various vacuum packs in the second vacuum pack mode, the operating conditions according to the type of bag to be packaged and the contents of the packaged items are pre-set from the control panel 210.

[0031] First, as shown in Figure 12, with the lid 30 open, the packaging bag 400 containing the items to be packaged is placed on the opening closing plate 240 that covers the opening of the deep recessed placement section 220 and on the flat placement section 230. At this time, the opening of the packaging bag 400 is placed on the lower seal block 270. Also, depending on the items to be packaged, the gas nozzle 290 is inserted and set into the opening of the packaging bag 400.

[0032] Next, as shown in Figure 13, when the lid 30 is closed, the vacuum pump 250 is activated and the air inside the chamber 100 is removed through the hole 255. When the air inside the chamber 100 is removed through the holes 255 for a set time (or until the set pressure is reduced), the air inside the packaging bag 400 is also removed at the same time, and a vacuum pack is formed.

[0033] Next, as shown in Figure 14, once the air inside the packaged bag 400 is removed, the piston 280 is activated to push up the lower seal block 270, causing the opening of the packaged bag 400 to be sandwiched between the lower seal block 270 and the upper seal block 300. Then, the heater wire provided in the lower seal block 270 is energized to melt and seal the opening of the vacuum-packed packaged bag 400. Once the production of the vacuum pack is complete, the chamber 100 is opened to the atmosphere, the lid 30 is opened, and the vacuum-packed packaged bag 400 is removed. This operation can be repeated to produce the same vacuum pack.

[0034] As described above, the deep-hole type vacuum packaging machine of this embodiment can have both a specification for manufacturing vacuum packs using the deep-hole mounting section 220 and a specification for vacuum packing using the flat mounting section 230. Furthermore, since the mounting portion of the lower seal block 270, the deep mounting portion 220, and the flat mounting portion 230 are integrally formed, the bottom shape of the chamber 100 is simple and easy to assemble.

[0035] Furthermore, the deep recessed mounting section 220 can accommodate a filling material 350 according to its application. In the first vacuum packing mode, the filling material 350 is placed at the bottom of the deep recessed mounting section 220, allowing for height adjustment of the small packaging bag 400 within the deep recessed mounting section 220. In the second vacuum packing mode, the deep recessed mounting section 220 is filled with a filling material 350 equivalent to its depth, reducing the amount of air in the chamber 100 and shortening the vacuuming (depressurization) operation time in the second vacuum packing mode.

[0036] Furthermore, the opening closing plate 240, which has the same height as the flat mounting section 230 and forms part of the flat mounting section, can be used not only to close the opening of the deep recess mounting section 220 but also as a pressing plate during hot pack manufacturing. Furthermore, since the gas supplied from the gas supply device 260 passes through the inside of the lower seal block 270 and is sealed in through the gas nozzle 290, the gas supply piping can be omitted.

[0037] The deep-hole vacuum packaging machine of this embodiment includes a main body 20 having a box-shaped deep-hole mounting section 220 with an opening and a flat mounting section 230 provided behind the deep-hole mounting section 220, a lid 30 that can be opened and closed by a hinge mechanism 40 provided behind the main body 20, a vacuum pump 250 provided inside the main body 20 to reduce the pressure inside the chamber 100 formed by the mounting surface of the main body 20 and the lid 30, and a sealing mechanism consisting of a lower sealing block 270 and an upper sealing block 300 that seals the opening of the bag to be packaged, and has a configuration that includes a first vacuum pack mode in which a bag to be packaged 400 is set in the deep-hole mounting section 220 to produce a vacuum pack, and a second vacuum pack mode in which a bag to be packaged is set on a flat mounting surface consisting of an opening closing plate 240 that closes the opening of the deep-hole mounting section and a flat mounting section 230 to produce a vacuum pack. This makes it possible to provide a deep-hole type vacuum packaging machine that combines specifications for manufacturing vacuum packs using a deep-hole mounting section and specifications for vacuum packing using a flat mounting section.

[0038] Furthermore, in the deep-hole vacuum packaging machine of this embodiment, the bottom surface of the chamber 100 is integrally formed with a mounting portion for the lower seal block 270, a deep-hole mounting portion 220, and a flat mounting portion 230. As a result, the shape of the bottom surface of the chamber 100 is simple, making it easy to assemble the deep-hole vacuum packaging machine.

[0039] Furthermore, the deep-hole vacuum packaging machine of this embodiment has a filling member 350 housed in a deep-hole mounting section 220. The deep-hole mounting section 220 is used as a member to adjust the height of the bag to be packaged 400 in the first vacuum pack mode, and is used as a member to reduce the volume of the deep-hole mounting section 220, which is not used in the second vacuum pack mode. As a result, in the first vacuum pack mode, the height of a small bag to be packaged can be adjusted within the deep-hole mounting section, and in the second vacuum pack mode, the amount of air in the chamber 100 is reduced because the filling member is housed in the deep-hole mounting section 220, thereby shortening the time required for the vacuuming (depressurization) operation in the second vacuum pack mode.

[0040] Furthermore, the deep-hole vacuum packaging machine of this embodiment further comprises a gas supply device 260 and at least one gas nozzle 290 that seals the bag to be packaged via the inside of the lower seal block 270 with gas from the gas supply device 260. As a result, the gas supplied from the gas supply device passes through the inside of the lower seal block and is sealed in through the gas nozzle, thus eliminating the need for gas supply piping.

[0041] Furthermore, in the deep-hole vacuum packaging machine of this embodiment, at least one winding 292 is attached to the front side of the lower seal block 270, and the lower opening of the bag to be packaged is fitted between the gas nozzle 290 and the winding 292. This allows gas to be sealed in while firmly gripping the lower opening of the bag to be packaged.

[0042] Furthermore, the deep-hole vacuum packaging machine of this embodiment further includes a support column 295 provided on the same side as the gas nozzle 290, and a pressing portion 330 provided on the upper seal block 300 that presses down on the upper opening of the bag to be packaged, which is placed in the support column 295. This allows gas to be sealed in while the upper opening of the bag to be packaged is firmly held in place.

[0043] Furthermore, in the deep-hole vacuum packaging machine of this embodiment, the opening closing plate 240 acts as a pressing plate for the packaging bag 400 when vacuum-packing an object containing a warm liquid. Thus, the opening closing plate can be used not only to close the opening of the deep-hole mounting section, but also as a pressing plate during hot-pack manufacturing.

[0044] <Second Embodiment> As described above, in order to prevent liquids such as broth from leaking out of the packaged bag 400 during hot pack manufacturing, it is possible to use a retaining plate such as an opening closing plate 240. However, if the opening closing plate 240 is not used, or even if the opening closing plate 240 is used, if the force of the liquid ejection due to boiling is strong, it is conceivable that the liquid may leak out of the packaged bag 400.

[0045] In the second embodiment, a drainage mechanism for handling liquid that has leaked out of the packaged bag 400 will be described.

[0046] Figure 15 is a cross-sectional view from the right side of the lid 30 of the deep-hole vacuum packaging machine 10 according to the second embodiment, with the lid open.

[0047] The deep-cut vacuum packaging machine 10 according to the second embodiment is a vacuum packaging machine that, in addition to the configuration of the deep-cut vacuum packaging machine 10 in the first embodiment described above, further includes a drain section 500. The drain section 500 has a configuration for discharging liquids such as broth that have leaked out of the bag to be packaged 400, that is, wastewater generated inside the main body 20, to the outside, and includes a drain opening 501, piping 502, and an on / off valve 503.

[0048] The drainage opening 501 is formed at the bottom of the deep-cut mounting section 220 and is an opening for discharging the drainage liquid accumulated at the bottom of the deep-cut mounting section 220. The bottom of the deep-cut mounting section 220 may be sloped so that the side with the drainage opening 501 is lower in order to guide the drainage liquid to the drainage opening 501.

[0049] The pipe 502 is a drainage pipe for discharging the wastewater flowing in from the drainage opening 501 to the outside of the main body 20. The pipe 502 is sloped so that the side with the pipe outlet 504 (drainage nozzle) is lower in order to guide the wastewater toward the pipe outlet 504.

[0050] The on / off valve 503 is installed in the piping 502 and is a manual valve capable of controlling the flow of drainage liquid through the piping 502.

[0051] As shown in Figure 15, the pipe outlet 504 and the on-off valve 503 are located at the lower front of the deep-cut vacuum packaging machine 10. By placing the pipe outlet 504 and the on-off valve 503 on the front side where the operation panel 210 is installed, access to them is made easier and operability is improved. Depending on the shape, size, and operability of the deep-cut vacuum packaging machine 10, the pipe outlet 504 and the on-off valve 503 can also be placed on the rear or side of the deep-cut vacuum packaging machine 10.

[0052] By closing the on-off valve 503, the inside of the chamber 100 can be sealed more precisely. In other words, by closing the on-off valve 503 and sealing the inside of the chamber 100, it is possible to prevent outside air from flowing in through the piping 502 during vacuuming (reducing pressure) operations. Furthermore, when a certain amount of drainage liquid has accumulated at the bottom of the deep recess mounting section 220, a tray or the like (not shown) can be placed below the piping outlet 504, and the on-off valve 503 can be opened to discharge the drainage liquid from the piping outlet 504.

[0053] In the second embodiment, the drain section 500 was described as being provided at the bottom of the deep mounting section 220, but the drain section 500 may also be provided at the bottom of the flat mounting section 230. Alternatively, the drain section 500 may be provided at the bottom of both the deep mounting section 220 and the flat mounting section 230.

[0054] As described above, the deep-hole vacuum packaging machine 10 of the second embodiment can properly process the wastewater generated inside the main body 20.

[0055] The embodiments of the present invention are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of Symbols]
