Description

【０００１】
【発明の属する技術分野】
本発明は、波形折り畳み濾材を枠体内に組み込んでなるエアフィルタをその製品形態において輸送するに適した梱包方法に係わり、特に、ごく簡易な包装を行なっただけのエアフィルタ単品をパレット上に複数個積載してエアフィルタの集合体とした上で該集合体に対して一括の梱包を行うエアフィルタの梱包方法に関する。
【０００２】
【従来の技術】
従来、捕集効率９９．９７％（ａｔ０．３μｍ）以上の性能を有するエアフィルタである高性能エアフィルタの輸送に当たっては、高性能エアフィルタが中性能エアフィルタ等下位グレードのエアフィルタに比較して、外力が加わった際の品質低下が著しく大きくなることから、外力の影響から守ることを最優先に考慮し中性能エアフィルタを含めた一般的な物品よりも厳重な梱包がなされている。具体的には、フィルタ製品を１乃至２個の単位で緩衝のための胴枠に包み込んだ上で段ボールまたは木製の箱に完全収納するといった方法が一般的である。
【０００３】
【発明が解決しようとする課題】
しかしながら、前記従来の梱包方法では、１乃至２個の製品単位で梱包されるため、梱包時や解梱時の作業効率及び作業性が低くなるばかりでなく、段ボール等の梱包資材の使用量が多くなりコスト高となると共に廃棄物量が増す等の問題点がある。
本発明は前記従来技術の梱包方法の問題点を解消し、作業効率及び作業性がよく、しかも資材の使用量が少なく、廃棄物量も少なくて済むエアフィルタの梱包方法を提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明のエアフィルタの梱包方法は前記目的を達成するべく、波形折り畳み濾材を枠体内に組み込んでなるエアフィルタの梱包方法において、台シートの四周縁に折り目を介して起立自在の起立片を連設すると共に台シートの底面の適宜箇所に足桁を設けた段ボールパレット上に、前記起立片を折り目に沿って上方に折り曲げ起立させて台シートをトレイ状に形成しながら、エアフィルタを複数個規則正しく載置し略立方体の集積体に形成し、少なくともエアフィルタの濾材露出面を保護板で保護すると共に、前記集積体の４側面外周にストレッチフィルムを張力をかけて巻回被覆することを特徴とする。
尚、本発明のエアフィルタの梱包方法は、エアフィルタの種類には特に限定はないが、外力の影響を受けやすい高性能エアフィルタの梱包に特に適しているものである。
【０００５】
【発明の実施の形態】
本発明の段ボールパレットは、四周縁に折り目を介して起立自在の起立片を連設した台シート（載荷板）と、該台シートの底面の適宜箇所に設けた足桁（桁状の脚部）とから構成される。
前記起立片は、エアフィルタを積載の際に、折り目に沿って上方に折り曲げて起立させると共に隣接する２片の起立片をその隣接部分で粘着テープ等で固定して、台シートをトレイ状に形成することで積載物の荷崩れを防止するものである。
また、前記足桁は、例えば、段ボールを多層に貼り合わせるか、合紙あるいは板紙等を折り曲げて断面方形の筒状体とするなどの方法で形成されたものを使用する。この足桁は、台シートの底面の適宜箇所に接着またはさらにカギ止め等の方法を用いて固定される。また、足桁の設置個所と設置数は、フォークリフトの爪の挿入位置とパレットの耐荷強度等を考慮して決められるが、パレットの短手方向に少なくとも両端の２列あるいはその中央を含めた３列に設置するのが製造コスト上最も好ましい。また、この場合、各列に設置される足桁を断続させて短手方向に順列に配置させることも可能で、その場合にはパレットの短手方向のみでなく長手方向にもフォークリフトの爪を挿入することが可能となる。
【０００６】
【実施例】
ここで、本発明のエアフィルタの梱包方法を、図面を参照して詳細に説明する。
先ず、図１及び図２に示すように、足桁１１を取り付けた段ボールパレット１０を用意し、パレット１０の長手方向１辺及びそれに隣接する短手方向の２辺の台シート起立片１２を折り目１３に沿って起こし上げ、隣接部分２ヶ所をテープ１４で止める。
次に図３に示すように、前記起立片１２を起こし上げた長手方向１辺のパレット１０上に保護板１５を立てる。
【０００７】
また、図４に示すように、高性能エアフィルタ製品３０を１台ずつ内容中にできるだけ空気が残存しないように注意しながらポリ袋内３１に収納し、開口部をテープ３２で封止する。
このように用意された高性能エアフィルタ製品３０を図５に示すように、段ボールパレット１０上に所定数量並列に載置する。図示の例では１１個並列に載置した。
次に、図６に示すように、段ボールパレット１０の残りの１辺の起立片１２を起こし上げ隣接する２辺の起立片１２，１２との隣接部分をテープ１４で止める。
【０００８】
次に、図７に示すように、前記パレット１０上に並列に載置されたフィルタ製品３０の集積体４０の上面に中敷き１６を敷き、この中敷き１６の上に前記ポリ袋３１に収納したフィルタ製品３０を同一方向に同一個数だけ並列に載置する。
【０００９】
次に、前記保護板１５と反対側のパレット１０長手方向１辺に、保護板１５を立てる。そして、このように、パレット１０上に２段に積載された略立方体のフィルタ製品３０の集積体４０，４０の側面外周にストレッチフィルム１７を適度に張力をかけながら巻き付け、梱包を終了する。
【００１０】
尚、中敷き１６は、１段のフィルタ集積体４０の上段にさらにフィルタ製品３０を積載する場合、上段に積載されるフィルタ製品３０からの衝撃等から下段のフィルタ集積体４０を保護するためのもので、該集積体４０の上面全体を覆うに充分な大きさを有することが必要である。材質は、段ボール紙などでよい。
【００１１】
また、保護板１５は、上下２段に積載され略立方体をなしたフィルタ集積体４０の４側面のうち、少なくとも外力の影響を受け易いエアフィルタ製品３０の濾材露出部、即ち、空気流開口面の前後面に当たる２側面を保護するためのもので、側面全体を覆うに充分な大きさを有することが必要である。材質は、段ボール紙等でよい。尚、保護板１５は、集積体４０の残りの２側面および集積体４０の天井面（上面）にも用いることができる。
【００１２】
ポリ袋３１は、フィルタ製品３０を水濡れ等から保護する機能を有する。尚、フィルタ製品３０を収納するポリ袋３１内に空気が残存すると、フィルタ製品３０を集積後に外周に巻くストレッチフィルム１７の圧迫により内容物のフィルタ製品３０が外力を受け、品質低下を招く恐れがあるので、ポリ袋３１内にはできるだけ空気が残存しないようにする必要がある。
また、ストレッチフィルム１７は、フィルタ集積体４０の側面外周の全面にまんべんなく巻き、集積体４０の全体を被覆できるまで巻く必要がある。一般には、フィルタ製品３０の幅寸法にもよるが大体６〜１０周程度巻くのがよい。
尚、パレットの台シートのタテ／ヨコ寸法及びパレット上に並べるフィルタ製品の数は、積載するフィルタ製品の外形寸法によって適宜決められる。
また、ここでは、フィルタ製品を２段に積載する例として説明したが、フィルタ製品の外形寸法によっては３段に積載することも可能である。
【００１３】
次に、本発明の梱包方法と従来の梱包方法とをそれぞれ実際に行って比較してみた。
本発明方法では、寸法８４０ｍｍ×１２３０ｍｍの段ボールパレットに高性能エアフィルタ（高さ６１０ｍｍ×幅１２２０ｍｍ×奥行（厚さ）７５ｍｍ）を２２台（１１台×２段）積載し、輸送を行った。
また、従来方法として、ポリ袋内に収納した高性能エアフィルタ（高さ６１０ｍｍ×幅１２２０ｍｍ×奥行（厚さ）７５ｍｍ）を２台を１単位として胴枠に包み込んだ上で段ボール箱に収納し、同時に、残り２０台の高性能エアフィルタを２台ずつ１０個の段ボール箱にそれぞれ収納し、合計で１１個の梱包体を作り、輸送を行った。
上記実施例と比較例による梱包、輸送を行った結果を表１に示す。
【００１４】
【表１】

【００１５】
表１から明かなように、本発明の梱包方法によれば、従来の方法に比較して、梱包、解梱に要する時間が短く、しかも梱包材廃棄量が少なくて輸送後の品質の低下も認められなかった。
【００１６】
【発明の効果】
このように、本発明の高性能エアフィルタの梱包方法は、従来の梱包方法に比較して、梱包時や解梱時の作業効率及び作業性を大幅に向上できると共に、梱包資材の使用量を大幅に低減できて省資源化が図れ、コストダウン及び廃棄物量の低減が図れる。

BACKGROUND OF THE INVENTION
The present invention relates to a packaging method suitable for transporting an air filter in which a corrugated folding filter medium is incorporated into a frame in its product form, and in particular, a plurality of single air filters that are simply packaged on a pallet. The present invention relates to a method for packing an air filter in which the air filters are assembled in a single package and then packed together for the aggregate.
[0002]
[Prior art]
Conventionally, when transporting high performance air filters, which are air filters with a collection efficiency of 99.97% (at 0.3 μm) or higher, high performance air filters are compared to lower grade air filters such as medium performance air filters. Since the deterioration of quality when external force is applied becomes significantly large, the packaging is more strict than general items including medium performance air filters with the highest priority given to protection from the influence of external force. . Specifically, it is common to wrap the filter product in one or two units in a cushioning frame and completely store it in a cardboard or wooden box.
[0003]
[Problems to be solved by the invention]
However, in the conventional packing method, since one or two product units are packed, not only the work efficiency and workability at the time of packing and unpacking are lowered, but also the amount of packing materials such as cardboard is used. There are problems such as an increase in cost and an increase in the amount of waste.
An object of the present invention is to provide a method for packing an air filter that solves the problems of the packing method of the prior art, has good work efficiency and workability, uses less material, and reduces the amount of waste. To do.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the air filter packaging method of the present invention is an air filter packaging method in which a corrugated folding filter medium is incorporated in a frame body, and a stand-up piece that can stand upright is connected to the four peripheral edges of the base sheet through folds. A plurality of air filters are formed on a cardboard pallet provided with leg girders at appropriate locations on the bottom surface of the base sheet, and the upright pieces are bent upward along the folds to form the base sheet in a tray shape. It is placed regularly and formed into a substantially cubic aggregate, and at least the exposed surface of the filter medium of the air filter is protected by a protective plate, and a stretch film is wound around the outer periphery of the four sides of the aggregate to cover it. And
The air filter packaging method of the present invention is not particularly limited in the type of air filter, but is particularly suitable for packaging of a high-performance air filter that is susceptible to external forces.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The corrugated cardboard pallet of the present invention includes a base sheet (loading plate) in which standing upright pieces that can freely stand up through folds at four peripheral edges, and a foot girder (girder-shaped leg portion) provided at an appropriate position on the bottom surface of the base sheet. ).
When the air filter is loaded, the upright piece is bent upward along the crease, and the two adjacent upright pieces are fixed with an adhesive tape or the like at the adjacent portion to form the base sheet in a tray shape. The formation prevents the load from collapsing.
The leg girder is formed by, for example, a method in which corrugated cardboard is laminated in multiple layers or a slip sheet or paperboard is bent to form a cylindrical body having a square cross section. The leg girder is fixed to an appropriate portion of the bottom surface of the base sheet by using a method such as adhesion or further locking. In addition, the installation location and the number of the foot girder are determined in consideration of the insertion position of the forklift claw and the load resistance strength of the pallet, etc., but at least 2 rows at both ends or the center thereof are included in the short direction of the pallet. Installation in a row is most preferable in terms of manufacturing cost. In this case, it is also possible to intermittently place the girder installed in each row and arrange it in the short direction, in which case the forklift pawls are not only in the short direction of the pallet but also in the long direction. It becomes possible to insert.
[0006]
【Example】
Here, the air filter packaging method of the present invention will be described in detail with reference to the drawings.
First, as shown in FIGS. 1 and 2, a corrugated cardboard pallet 10 to which a foot girder 11 is attached is prepared, and pedestal sheet upright pieces 12 on one side in the longitudinal direction of the pallet 10 and two sides in the lateral direction adjacent thereto are folded. 13 is raised along with the tape 14 and the two adjacent portions are stopped with the tape 14.
Next, as shown in FIG. 3, a protective plate 15 is erected on the pallet 10 on one side in the longitudinal direction where the upright piece 12 is raised.
[0007]
Further, as shown in FIG. 4, the high-performance air filter products 30 are housed one by one in a plastic bag 31 with care so that air does not remain in the contents as much as possible, and the opening is sealed with a tape 32.
The high-performance air filter product 30 thus prepared is placed in parallel on the cardboard pallet 10 in a predetermined amount as shown in FIG. In the illustrated example, 11 were placed in parallel.
Next, as shown in FIG. 6, the remaining upright piece 12 of the corrugated cardboard pallet 10 is raised and the adjacent portion between the adjacent

upright pieces

12 and 12 is stopped with the tape 14.
[0008]
Next, as shown in FIG. 7, an insole 16 is laid on the upper surface of the assembly 40 of the filter products 30 placed in parallel on the pallet 10, and the filter housed in the poly bag 31 on the insole 16. The same number of products 30 are placed in parallel in the same direction.
[0009]
Next, the protective plate 15 is erected on one side in the longitudinal direction of the pallet 10 opposite to the protective plate 15. In this manner, the stretch film 17 is wound around the side surface outer periphery of the

aggregates

40 and 40 of the substantially cubic filter products 30 stacked in two stages on the pallet 10 while applying appropriate tension, and the packaging is finished.
[0010]
The insole 16 is used to protect the lower filter assembly 40 from an impact or the like from the filter product 30 loaded on the upper stage when the filter product 30 is further loaded on the upper stage of the filter assembly 40 of the first stage. Therefore, it is necessary to have a size sufficient to cover the entire upper surface of the integrated body 40. The material may be corrugated paper.
[0011]
Further, the protective plate 15 is a filter medium exposed portion of the air filter product 30 that is susceptible to at least an external force, that is, an air flow opening surface, among the four side surfaces of the filter assembly 40 that are stacked in two steps on the upper and lower sides. It is intended to protect the two side surfaces corresponding to the front and rear surfaces, and needs to be large enough to cover the entire side surface. The material may be corrugated paper. The protection plate 15 can also be used on the remaining two side surfaces of the integrated body 40 and the ceiling surface (upper surface) of the integrated body 40.
[0012]
The plastic bag 31 has a function of protecting the filter product 30 from water and the like. If air remains in the plastic bag 31 that houses the filter product 30, the filter product 30 of the contents may be subjected to external force due to the compression of the stretch film 17 wound around the outer periphery after the filter product 30 is accumulated, and the quality may be deteriorated. Therefore, it is necessary to prevent air from remaining in the plastic bag 31 as much as possible.
In addition, the stretch film 17 needs to be wrapped evenly over the entire outer periphery of the side surface of the filter assembly 40 until the entire assembly 40 can be covered. In general, although it depends on the width dimension of the filter product 30, it is preferable to wind about 6 to 10 turns.
The vertical / horizontal dimensions of the base sheet of the pallet and the number of filter products arranged on the pallet are appropriately determined according to the external dimensions of the filter products to be loaded.
In addition, here, an example in which filter products are stacked in two stages has been described. However, depending on the outer dimensions of the filter products, the filter products can be stacked in three stages.
[0013]
Next, the packing method of the present invention and the conventional packing method were actually performed and compared.
In the method of the present invention, 22 units (11 units × 2 steps) of high-performance air filters (height 610 mm × width 1220 mm × depth (thickness) 75 mm) were loaded on a cardboard pallet having dimensions of 840 mm × 1230 mm and transported.
In addition, as a conventional method, two high performance air filters (height 610 mm x width 1220 mm x depth (thickness) 75 mm) housed in a plastic bag are wrapped in a trunk frame as one unit and then housed in a cardboard box. At the same time, the remaining 20 high-performance air filters were each housed in 10 cardboard boxes, making a total of 11 packages and transported.
Table 1 shows the results of packaging and transportation according to the above examples and comparative examples.
[0014]
[Table 1]

[0015]
As is clear from Table 1, according to the packing method of the present invention, the time required for packing and unpacking is shorter than that of the conventional method, and the amount of packing material discarded is small, resulting in a decrease in quality after transportation. I was not able to admit.
[0016]
【The invention's effect】
As described above, the packing method of the high performance air filter of the present invention can greatly improve the work efficiency and workability at the time of packing and unpacking as compared with the conventional packing method, and also reduces the amount of packing material used. It can be greatly reduced, saving resources, reducing costs and reducing the amount of waste.
