JP 2000-095276 A

  However, in the conventional packing apparatus shown in Patent Document 1, the internal shape of the box is a rectangular parallelepiped and the bottom area is relatively large. Therefore, if a large amount of refrigerant gas does not leak from the air conditioner, it will leak. Thus, the concentration of the refrigerant gas staying in the box does not increase to the extent that it can be detected by the refrigerant sensor. Therefore, it takes a long time until the refrigerant sensor senses that the refrigerant gas has leaked from the air conditioner, and there is a problem that the refrigerant gas leak cannot be detected immediately.

  Moreover, it is necessary to put a packing material between the box and the air conditioner that is a packaged object in order to reduce the impact during the transfer. For this reason, there are a large number of gaps in the box. Therefore, when the refrigerant gas leaks from the air conditioner, the refrigerant gas and a large amount of air coexist in the box. there were.

  In order to solve such a problem, a packaging device that can reduce the amount of air coexisting with the refrigerant gas even if the refrigerant gas leaks from the air conditioner is obtained. is there.

  The packaging device according to the present invention is a packaging device for packaging equipment using a refrigerant gas having an average molecular weight greater than that of air, the first packaging body covering at least the lower surface of the equipment, and the first packaging body. And a second package body that seals the device and a small recess provided in a portion of the first package body that covers the lower surface of the device.

  In the packaging device according to the present invention, even if the refrigerant gas leaks from the air conditioner, the amount of air coexisting with the refrigerant gas can be reduced.

  The present invention will be described with reference to the accompanying drawings. Throughout the drawings, the same reference numerals indicate the same or corresponding parts, and redundant description thereof will be simplified or omitted as appropriate.

Embodiment 1 FIG.
1 to 3 relate to Embodiment 1 of the present invention. FIG. 1 is a cross-sectional view showing the overall configuration of the packaging device, FIG. 2 is a perspective view showing a lower packing body of the packaging device, and FIG. It is a figure explaining the packing procedure of the to-be-packaged object by an apparatus.

  In FIG. 1, reference numeral 1 denotes an object to be packed that is to be packed by the present packing apparatus. This packaged item is a device using a refrigerant such as an air conditioner or a refrigerator. Here, the to-be-packaged object 1 is assumed to be an air conditioner, and its shape is assumed to be a substantially rectangular parallelepiped shape.

  Reference numeral 2 denotes an outer box formed of a rectangular parallelepiped box having an open upper surface. The inner dimension of the outer box 2 is sufficiently large with respect to the outer dimension of the article 1 to be packed. The article to be packed 1 is accommodated in the outer box 2 while being packed by the lower packing body 3 and the upper packing body 4. Then, the upper open portion of the outer box 2 is covered with the upper lid 5.

  The lower packaging body 3 and the upper packaging body 4 accommodate the article to be packaged 1 in a sealed state in these packages, and between the article to be packaged 1 accommodated in the outer box 2 and the inner wall of the outer box 2. It also serves as a cushioning material that fills the gaps that are formed and protects the article to be packed 1 from impacts during transportation.

  On the upper surface side of the lower packaging body 3, a lower housing portion 3 a is formed that is a concave portion matched with the shape of the lower surface of the article 1 to be packed. And the to-be-packaged object 1 is accommodated in the lower accommodating part 3a of this lower packaging body 3, and the lower packaging body 3 has covered at least the lower surface of the to-be-packaged object 1 from the lower side of the to-be-packaged object 1. It becomes.

  On the lower surface side of the upper package body 4, an upper housing portion 4 a that is a concave portion matched with the upper surface shape of the article 1 is formed. Then, the upper package 4 is placed on the package 1 from above the package 1 such that the package 1 is accommodated in the upper accommodating portion 4a. In this way, the upper packaging body 4 packs the article to be packed 1 together with the lower packaging body 3 in a sealed state.

  At this time, in order to further improve the sealing performance, a sealing material, packing, or the like may be provided in a portion where the lower packing body 3 and the upper packing body 4 are combined. Alternatively, the inner peripheral side of the thickness is cut off at one of the upper end of the lower packing body 3 and the lower end of the upper packing body 4 so that the upper end of the lower packing body 3 and the lower end of the upper packing body 4 are fitted. On the other hand, the outer peripheral side of the thickness may be cut out.

  Here, the terms “lower side” and “lower surface” are positioned below the gravitational direction when the article 1 packed in the lower packing body 3 and the upper packing body 4 is normally placed. The terms “upper side” and “upper surface” mean that they are located on the upper side in the gravity direction, and the same applies to the following.

The structure of the lower package 3 is shown in FIG. On the lower surface of the lower housing 3 a of the lower packaging body 3, that is, on the portion of the lower packaging body 3 that covers the lower surface of the article 1 to be packaged, a slope portion 6 composed of four slopes constituting a substantially inverted quadrangular frustum shape is formed. Has been. And by this slope part 6, the space of the shape where the horizontal cross-sectional area becomes small gradually is formed in the lower surface of the lower accommodating part 3a of the lower packing body 3 as it goes below from the upper direction. The inclined surface portion 6 may have a substantially frustoconical filed bowl shape or the like as long as it forms a space having a shape in which the horizontal cross-sectional area increases toward the upper side and the horizontal cross-sectional area decreases toward the lower side. Here, it is preferable that the slope portion 6 covers the entire lower surface of the article 1 as much as possible.
At the lowermost portion of the slope portion 6, a small concave portion 7 is formed which is further depressed by one step from the slope portion 6.

Returning again to FIG. 1, a gas sensor 8 that senses and detects refrigerant gas used in the air conditioner that is the packed object 1 is attached in the small recess 7. The refrigerant gas used in the packaged object 1 (air conditioner) is a flammable (more precisely, slightly flammable) gas. In addition, this refrigerant gas has a higher average molecular weight than air, and has the property of sinking downward in the direction of gravity in air. Specifically, as this refrigerant gas, for example, difluoromethane (CH ₂ F ₂ : R32), tetrafluoropropane (CF ₃ CF═CH ₂ : HFO-1234yf), propane (R290), propylene (R1270), ethane ( R170), butane (R600), isobutane (R600a), 1.1.1.2- tetrafluoroethane _{(C 2 H 2 F 4:} R134a), pentafluoroethane _{(C 2 HF 5: R125)} , 1.3 3.3 (Tetrafluoro-1-propene (CF ₃ —CH═CHF: HFO-1234ze)) or the like (mixed) refrigerant composed of one or more refrigerants selected from among them can be used.

  The gas sensor 8 is provided with a leakage display portion 9 for displaying the detection result of the refrigerant gas by the gas sensor 8. The leakage display section 9 is arranged so that the display can be confirmed from the outside of the lower package 3. Therefore, it can be confirmed from the outside of the package whether or not the gas sensor 8 senses the refrigerant gas in a state where the package 1 is packed by the lower package 3 and the upper housing 4a.

  In addition, when the lower packing body 3 and the upper packing body 4 which packed the to-be-packaged goods 1 are accommodated in the outer box 2, the detection result of the gas sensor 8 can also be confirmed from the outside of the outer box 2. In addition, a window part may be provided in the outer box 2 in accordance with the position of the leakage display part 9 in the outer box 2.

FIG. 3 shows a procedure for packing the article to be packed 1 in the packing apparatus configured as described above.
First, as shown in FIG. 3A, the state of FIG. Next, when the article 1 and the lower packing body 3 in the state of FIG. 3B are accommodated in the outer box 2, the state of FIG. In this state, the upper packing body 4 with the opening of the upper housing portion 4a facing downward is covered from above the packing object 1, and the packing object 1 is packed inside the lower packing body 3 and the upper packing body 4. To do. Then, the upper opening of the outer box 2 is covered with the upper lid 5 so that the packaging shown in FIG. 1 is completely completed.

  In the state in which the package 1 is packed in the lower package 3 and the upper package 4 configured in this way, when the refrigerant gas leaks from the package 1, the refrigerant gas is heavier than air and thus sealed. It flows downward in the package. Then, the refrigerant gas flows downward along the slope 6 of the lower packing body 3 and finally accumulates in the small recess 7. In this way, the leaked refrigerant gas collects in the small concave portion 7 without diffusing to the entire bottom surface of the outer box 2, so that even if the leaked refrigerant gas is small, it can be detected by the gas sensor 8. It becomes.

  In addition, since the refrigerant gas used here becomes easy to burn when mixed with oxygen in the air, after packing the article 1 to be packed with the lower packing body 3 and the upper packing body 4, oxygen in these packing bodies. You may make it perform the process which reduces a density | concentration. In this case, specific examples of measures for reducing the oxygen concentration in the packing body include evacuating the inside of the packing body using a vacuum pump or a vacuum cleaner, or packing an inert gas such as nitrogen or argon. It may be injected inside the body.

  And in order to be able to perform such a treatment easily, at least one of the lower packing body 3 and the upper packing body 4 is provided with an air suction port, or an inert gas injection port and an air discharge valve. It may be provided. The specific structure of these air suction ports and inert gas injection ports is, for example, a structure that opens and opens only when a thin tube for air suction or gas injection is inserted and closes naturally when the tube is pulled out. Or a structure having an open / close valve.

  Moreover, since it will become easy to burn if there is much water content contained in the mixed gas containing the refrigerant gas used here, when packing the to-be-packaged object 1 with the lower packing body 3 and the upper packing body 4, You may make it put a desiccant with the to-be-packaged goods 1 in the package. At this time, the desiccant may be disposed on the slope portion 6 or the like between the lower package body 3 and the article to be packed 1, or may be disposed at another location within the package body. Good.

  Furthermore, an identification display having information (for example, a production number) unique to the packaged object 1 is printed or attached to the packaged object 1, and the lower package 3 used for packing the packaged object 1 and The same identification display may be provided on at least one of the upper packing bodies 4. In this way, by keeping the same identification and indication on the article to be packed 1 and the package, the product and the package that is the article to be packed 1 are traced from the purchase to the disposal by the user. Can be monitored. And it is possible to suppress illegal dumping etc. by tracking the to-be-packaged object 1 and a package in this way.

  In addition, even if it attaches the IC tag which memorize | stored the same ID to the to-be-packaged object 1 and a package as an identification display provided in the to-be-packaged object 1 and a package, the same effect can be show | played. Further, this identification display (manufacturing number, IC tag, etc.) may be provided not only on the packaged object 1 and the package but also on the outer box 2 and the upper lid 5.

  The packaging device configured as described above is a packaging device for packaging equipment using refrigerant gas having a higher average molecular weight than air, and is a first packaging body that covers at least the lower surface of the equipment to be packed. Combined with the lower packing body and the lower packing body (first packing body), the upper packing body, which is a second packing body that seals the equipment, and the equipment in the lower packing body (first packing body) A small recess provided in a portion covering the lower surface.

  For this reason, the refrigerant gas leaked from the device to be packed flows downward in the sealed package and finally accumulates in a small recess having a small volume, so that the air coexisting with the refrigerant gas The amount can be reduced.

  In addition, a slope portion that forms a space whose horizontal cross-sectional area gradually decreases from the top to the bottom in the portion of the lower package covering the lower surface of the device is provided, and the small recess is provided at the bottom of the slope portion. By doing so, it is possible for the refrigerant gas leaked from the device to be packed to smoothly gather into the small recess along the inclined surface of the slope portion.
