Description

本発明は、事務用製品、家電製品、精密機器などの被梱包体を梱包する際に使用される梱包用緩衝部材に関し、特に、重量が大きい被梱包体の下面に形成される被支持面（梱包用緩衝部材に支持される面）の面積が小さいため、前記小さな被支持面を支持する梱包用緩衝部材の支持面に大きな集中荷重が加わる場合に好適に使用される梱包用緩衝部材に関する。   The present invention relates to a cushioning member for packing used when packing a packaged body such as an office product, a household appliance, or a precision instrument, and in particular, a supported surface formed on the lower surface of the packaged body having a large weight ( Since the area of the surface supported by the packing cushioning member is small, the present invention relates to a packaging cushioning member that is preferably used when a large concentrated load is applied to the supporting surface of the packing cushioning member that supports the small supported surface.

被梱包体を外部からの衝撃より保護するため、輸送条件や被梱包体の質量、製品強度などの条件より、梱包用緩衝部材の材質、厚さ、緩衝受け面積について必要量を算出しているが、被梱包体の一部分に突起部が付いていたり、空洞部や薄肉部を有する形状の場合、必要な緩衝受け面積を均一に得ることができない場合がある。そのような場合、梱包用緩衝部材となる発泡樹脂成形品の一部分を異なる発泡倍率に成形したり、一部分を別材質の成形品に置き換えることで必要な緩衝面積を確保している。   In order to protect the package body from external impacts, the required amount is calculated for the material, thickness, and buffer receiving area of the packing cushioning material based on conditions such as transportation conditions, the mass of the package body, and product strength. However, when a protrusion is attached to a part of the packaged body or a shape having a hollow part or a thin part, the required buffer receiving area may not be obtained uniformly. In such a case, a necessary cushioning area is ensured by molding a part of the foamed resin molded product to be a cushioning member for packing at a different expansion ratio or replacing a part with a molded product of a different material.

前記梱包用緩衝部材としては、下記の技術が従来公知である。
（特許文献１：特開平０８−１５１０７８号公報）
特許文献１には、被梱包体を梱包箱の内部に緩衝支持する梱包用緩衝部材であって、梱包箱内に配置される一対のブロック状の緩衝材本体を、前記一対の緩衝材本体に両端部が嵌合する板状連結部材により連結した梱包用緩衝部材が記載されている。
この特許文献１記載の技術は、緩衝材本体と連結材とを接着剤を用いることなく、簡単に組み立てたり分解することができると共に供給時や回収時の輸送を効率的に行うことができて、リサイクルを容易とし地球環境保護に最適な梱包用緩衝材を提供することができる。 As the packing cushioning member, the following techniques are conventionally known.
(Patent Document 1: Japanese Patent Application Laid-Open No. 08-1551078)

（前記特許文献１記載の技術の問題点）
特許文献１記載の技術では、重量の大きな被梱包体の下面を支持する梱包用緩衝部材としては使用できない。
（前記特許文献２〜４記載の技術の問題点）
特許文献２〜４記載の技術では、同一面内で部分的に緩衝部材の材質が異なると外部からの衝撃が受け面全域に加わる場合に、異なる材質特性により緩衝部材の歪量が異なる事から被梱包体に不均一な衝撃応答応力を発生させることとなり、被梱包体の筐体を損傷させることになる。また、部分的に発泡倍率が異なる発泡成形品を成形するには型が複雑になり、コスト高となる。 (Problems of the technology described in Patent Document 1)
The technique described in Patent Document 1 cannot be used as a cushioning member for packing that supports the lower surface of a heavy packaged body.
(Problems of the techniques described in Patent Documents 2 to 4)
In the techniques described in Patent Documents 2 to 4, if the shock absorbing material is partially different within the same plane, and the impact from the outside is applied to the entire receiving surface, the amount of strain of the shock absorbing member varies depending on the different material characteristics. As a result, non-uniform impact response stress is generated in the packaged body, and the casing of the packaged body is damaged. In addition, a mold becomes complicated to form a foam molded product having partially different foaming ratios, resulting in an increase in cost.

また、発泡倍率の低い部分と高い部分とを同時成形する場合には、発泡倍率の低い部分に対する高い部分の発泡倍率の比（発泡倍率比）を余り大きくすることができない。同一材料を使用する同時発泡成形の場合の前記発泡倍率比は１.５くらいにしかならない。この場合、重量が大きい被梱包物体の下面と、前記緩衝部材の被梱包体支持面との接触面積が小さい場合には、被梱包体支持面を硬く形成するために発泡倍率を低くすると、前記被梱包体支持面以外の部分の緩衝部材の発泡倍率も低くなってしまう。すなわち、緩衝部材全体の発泡倍率が低くなるので、緩衝部材の材料の消費量が多くなって、コスト高となってしまう。
さらに、梱包用緩衝部材の被梱包体支持面との接触面積が小さく重量が大きい被梱包体を、前記被梱包体支持面で支持する場合、低コストの発泡倍率が高い材料で前記被梱包体支持面を形成すると、被梱包体支持面が凹んだり、陥没したりすることにより変形または損傷してしまう。この場合、前記重量の大きい被梱包体は傾斜するため、梱包作業や輸送作業に支障をきたすという問題点もある。 Moreover, when simultaneously molding a portion having a low expansion ratio and a portion having a high expansion ratio, the ratio of the expansion ratio of the high portion to the portion having a low expansion ratio (foaming ratio) cannot be increased too much. In the case of simultaneous foam molding using the same material, the expansion ratio is only about 1.5. In this case, if the contact area between the lower surface of the packaged object having a large weight and the packaged body support surface of the cushioning member is small, the foaming ratio is lowered to form the packaged body support surface hard, The expansion ratio of the cushioning member other than the package support surface is also lowered. That is, since the expansion ratio of the entire cushioning member is reduced, the amount of consumption of the material of the cushioning member is increased and the cost is increased.
Further, when the packing body having a small contact area with the packing body support surface of the packing cushioning member and having a large weight is supported by the packing body support surface, the packing body is made of a low-cost material with a high expansion ratio. When the support surface is formed, the packaged body support surface is deformed or damaged by being recessed or depressed. In this case, since the to-be-packaged body having a large weight is inclined, there is a problem that the packing work and the transportation work are hindered.

本発明は前記事情に鑑み、次の記載内容（Ｏ01），（Ｏ02）を技術的課題とする。
（Ｏ01）発泡倍率の高い梱包用緩衝部材を使用する際、前記被梱包体の重量が大きく且つ前記梱包用緩衝部材との接触面積が小さい場合であっても、前記梱包用緩衝部材が大きく変形したりまたは損傷したりするのを防止すること。

Since the third buffer member 31 and the fourth buffer member 41 support the right side portion (Y side portion) that is lighter than the left side portion (−Y side portion) of the image forming apparatus (packaged body) U, the third buffer member 31 and the fourth buffer member 41 1. The packaging plate members used in the second packaging plate members 11 and 21 are not used.
In addition, when the big weight of a to-be-packaged body is added to the said 3rd buffer member 31 and the 4th buffer member 41, it is possible to use the plate-shaped member for packing.

（実施例１の作用）
図１において、前記実施例１の第１〜第４梱包用緩衝部材１１〜４１は、図示しない直方体形状のダンボール紙製の梱包用箱または木の枠体等の底面の４つのコーナに配置して使用される。実施例１で使用される被梱包体としての画像形成装置Ｕは、左側（−Ｙ側）部分の重量が右側部分よりも重く構成されている。このため、被梱包体（画像形成装置）の左側部分（−Ｙ側部分）の下面を支持する梱包用緩衝部材には右側部分（Ｙ側部分）下面を支持する梱包用緩衝部材よりも大きな荷重が加わる。 (Operation of Example 1)
In FIG. 1, the first to fourth packing cushioning members 11 to 41 of the first embodiment are arranged at four corners on the bottom of a rectangular parallelepiped cardboard packaging box or a wooden frame (not shown). Used. The image forming apparatus U as a packaged body used in Embodiment 1 is configured such that the left side (−Y side) portion is heavier than the right side portion. For this reason, the packing buffer member that supports the lower surface of the left side portion (−Y side portion) of the packaged body (image forming apparatus) has a larger load than the packing buffer member that supports the lower surface of the right side portion (Y side portion). Will be added.

前記４個の梱包用緩衝部材１１〜４１の中の第１梱包用緩衝部材１１および第２梱包用緩衝部材２１は、被梱包体の左側（−Ｙ側）部分を支持する位置に配置されており、右側（Ｙ側）部分を支持する第３，第４梱包用緩衝部材３１，４１よりも大きな荷重が加わる。
したがって、第１、第２梱包用緩衝部材１１，２１は、梱包用緩衝部材本体１２，２２と、その板状部材装着面１２ａ，２２ａに着脱可能に装着される梱包用板状部材１３，２３とにより構成されるが、第３、第４梱包用緩衝部材３１，４１は、梱包用板状部材が使用されない。 The first packing cushioning member 11 and the second packing cushioning member 21 among the four packing cushioning members 11 to 41 are arranged at positions that support the left (−Y side) portion of the packaged body. Thus, a larger load is applied than the third and fourth packing cushioning members 31 and 41 that support the right (Y side) portion.
Accordingly, the first and second packing cushioning members 11 and 21 are the packaging cushioning member bodies 12 and 22 and the packaging platelike members 13 and 23 that are detachably attached to the platelike member mounting surfaces 12a and 22a. However, the third and fourth packing buffer members 31 and 41 do not use packing plate-like members.

前記梱包用板状部材１３，２３は、梱包用緩衝部材本体１２，２２よりも硬い材料により構成されるので、その上面に形成された被梱包体支持面に載置された被梱包体としての画像形成装置Ｕの重量が大きく且つ前記画像形成装置Ｕと前記被梱包体支持面との接触面積が小さい場合であっても、梱包用板状部材１３，２３の上面に形成された被梱包体支持面が凹んだり、陥没したりし難くい。また、画像形成装置Ｕの大きな重量または輸送時等に画像形成装置に作用する上下方向の衝撃等は、前記梱包用緩衝部材本体１２，２２よりも硬い前記梱包用板状部材１３，２３材料から前記梱包用緩衝部材本体１２，２２の板状部材装着面１２ａ，２２ａの広い面積部分に分散して伝達される。このため、前記梱包用緩衝部材本体１２，２２は発泡倍率の高い材料により構成しても、梱包用緩衝部材本体１２，２２の板状部材装着面１２ａ，２２ａが凹んだり、陥没したりし難くい。
このため、梱包用緩衝部材本体１２，２２の変形または損傷を防止することができるので、画像形成装置Ｕに局所的な大きな応力が発生することを抑制することができる。 Since the packing plate-like members 13 and 23 are made of a material harder than the packing shock-absorbing member main bodies 12 and 22, the packing plate-like members 13 and 23 are used as packing objects that are placed on the packing object support surface formed on the upper surface thereof. Even if the weight of the image forming apparatus U is large and the contact area between the image forming apparatus U and the support body to be packed is small, the packaged body formed on the top surfaces of the packing plate-like members 13 and 23. The support surface is difficult to dent or sink. Also, the large weight of the image forming apparatus U or the impact in the vertical direction acting on the image forming apparatus during transportation or the like is caused by the material of the packing plate-like members 13 and 23 that is harder than the packing buffer member bodies 12 and 22. It is distributed and transmitted to a wide area portion of the plate-like member mounting surfaces 12a, 22a of the cushioning member main bodies 12, 22 for packing. For this reason, even if the packing buffer member bodies 12 and 22 are made of a material having a high expansion ratio, the plate-like member mounting surfaces 12a and 22a of the packing buffer member bodies 12 and 22 are unlikely to be recessed or depressed. Yes.
For this reason, since deformation or damage to the packing buffer member main bodies 12 and 22 can be prevented, it is possible to suppress the occurrence of large local stress in the image forming apparatus U.

前記梱包用緩衝部材本体１２，２２に装着された梱包用板状部材１３，２３により、梱包用緩衝部材本体１２，２２に接触している梱包用板状部材１３，２３の下面の全面積が、緩衝面積となる。このため、梱包用緩衝部材本体１２，２２に加わる荷重が分散されるので、衝撃により画像形成装置（被梱包体）に加わる上下方向の衝撃力を分散して緩和することができる。
外部からの衝撃が被梱包体を支持する梱包用板状部材１３，２３を介して、梱包用緩衝部材本体１２，２２の板状部材装着面１２ａ，２２ａに伝達される。このとき、前記板状部材装着面１２ａ，２２ａの前記梱包用板状部材１３，２３の下面との接触面全体に衝撃力が分散して伝達される。このため、前記接触面全体が均一に歪むことで被梱包体に不均一な応力発生を抑制することができる。
これにより、輸送環境における外部の衝撃から、被梱包体の一部に局所的応力などを発生させることなく、被梱包体の損傷を未然に防止することを可能にする。 Due to the packing plate-like members 13 and 23 mounted on the packing buffer member main bodies 12 and 22, the entire area of the lower surface of the packing plate-like members 13 and 23 contacting the packing buffer member main bodies 12 and 22 is reduced. It becomes a buffer area. For this reason, since the load applied to the packing cushioning member main bodies 12 and 22 is dispersed, the impact force in the vertical direction applied to the image forming apparatus (packaging body) due to the impact can be dispersed and reduced.
The impact from the outside is transmitted to the plate-like member mounting surfaces 12a and 22a of the packing cushioning member main bodies 12 and 22 through the packing plate-like members 13 and 23 that support the object to be packed. At this time, the impact force is distributed and transmitted to the entire contact surface of the plate member mounting surfaces 12a, 22a with the lower surfaces of the packing plate members 13, 23. For this reason, generation | occurrence | production of a nonuniform stress can be suppressed to the to-be-packaged body because the said whole contact surface is distorted uniformly.
This makes it possible to prevent damage to the packaged body from external impacts in the transport environment without causing local stress or the like in a part of the packaged body.

また、前記第１、第２の梱包用緩衝部材１１，２１は、前記梱包用緩衝部材本体１２，２２の板状部材装着面１２ａ，２２ａに設けた板状部材嵌合孔（嵌合凹部）１２ｂ，２２ｂと前記梱包用板状部材１３，２３の下面に設けた円柱状の嵌合凸部１３ｂ，２３ｂとが嵌合、離脱可能に形成されているので、前記板状部材装着面１２ａ，２２ａおよび前記梱包用板状部材１３，２３の下面を位置決めした状態で容易に装着することができる。梱包用緩衝部材本体１２，２２の所定位置に梱包用板状部材１３，２３を装着する作業を行う際の作業性を向上させることが可能となる。
したがって、装着時の位置ずれと、衝撃緩衝時の梱包用板状部材１３，２３の位置ずれとを防止することができる。このため、衝撃緩衝時に凹凸部の嵌合により梱包用板状部材１３，２３が梱包用緩衝部材本体１２，２２と分離することなく、輸送時における連続的な衝撃についても、衝撃力を吸収することができる。 The first and second packing cushioning members 11, 21 are plate-like member fitting holes (fitting recesses) provided in the plate-like member mounting surfaces 12 a, 22 a of the packing cushioning member bodies 12, 22. 12b, 22b and cylindrical fitting projections 13b, 23b provided on the lower surfaces of the packing plate-like members 13, 23 are formed to be detachable, so that the plate-like member mounting surface 12a, 22a and the packing plate-like members 13 and 23 can be easily mounted in a state in which the lower surfaces thereof are positioned. It is possible to improve the workability when performing the work of attaching the packing plate-like members 13 and 23 to the predetermined positions of the packing shock-absorbing member main bodies 12 and 22.
Therefore, it is possible to prevent the positional deviation at the time of mounting and the positional deviation of the packing plate members 13 and 23 at the time of shock buffering. For this reason, the shock-absorbing force is absorbed even for continuous impacts during transportation without the packing plate-like members 13 and 23 being separated from the packing shock-absorbing member main bodies 12 and 22 due to the fitting of the concavo-convex portions during shock buffering. be able to.
