Description
本発明は、粒状配合肥料の荷造り方法に関する。詳しくは少量多品種の粒状配合肥料を効率よく、且つ安価に荷造りする方法に関する。 The present invention relates to a method for packing granular compound fertilizer. More specifically, the present invention relates to a method for packing a small amount and a variety of granular compound fertilizers efficiently and inexpensively.
近年、農業就労者の高年齢化、就業者数の減少、兼業農家の増加から、より省力型として、植物の生育期間に合わせて唯１回の施肥で収穫迄肥効が持続する一発型肥料が要求されている。特に、最近、樹脂等で粒状肥料表面を被覆して肥料成分の溶出期間を種々調節した粒状被覆肥料と粒状化成肥料等を配合して、各種植物の地域別および土壌種別の生育期間に合わせて肥効を持続させるようにした粒状配合肥料が要求されている。このような各種植物の地域別および土壌種別に対応した粒状配合肥料を製造しようとすると、少量多品種となりその製品の数は数千種類となる。 In recent years, with the aging of agricultural workers, the decrease in the number of workers, and the increase in part-time farmers, as a labor-saving type, one-time fertilization according to the growing period of the plant and the fertilization effect continues until harvesting Fertilizer is required. In particular, recently, granular coated fertilizers and granular fertilizers, etc., which have been coated with resin and coated with granular fertilizer surfaces to adjust the elution period of fertilizer components in various ways, are combined with the growth period of various plants by region and soil type. There is a demand for a granular compound fertilizer that maintains its fertilization effect. If it is going to manufacture such a granular compound fertilizer corresponding to the region classification and soil classification of such various plants, it will become a small amount many varieties, and the number of the products will be thousands.
少量多品種で数千種類の粒状配合肥料の荷造り方法として、自動配合機で配合された粒状配合肥料を、自動袋詰装置を使用して、製品専用の細孔の無いいわゆるノーピン包装袋を使用して充填、シールし、パレット上に段積み時に包装袋を固定するための水性接着剤を自動塗布機を使用して、包装袋の上面中央部に、１／２〜１／５面に相当する範囲を塗布した後、パレット上に段積みする方法が知られている（特許文献１参照。）。
しかしながら、このような従来の方法では、数千種類の製品専用包装袋を必要とするため、置場、仕分け等が極めて煩雑となり、また包装袋版代が膨大となるため、能力低下およびコスト高の問題があり、荷造り対応は極めて困難である。
However, such conventional methods require thousands of types of product-specific packaging bags, so that placement and sorting become extremely complicated, and the packaging bag plate cost becomes enormous. There are problems and packing is extremely difficult.
本発明は、少量多品種の粒状配合肥料を効率よく、且つ安価に荷造りする方法を提供することにある。 An object of the present invention is to provide a method for packing a small amount of various kinds of granular compound fertilizers efficiently and inexpensively.
本発明者は、粒状配合肥料の荷造り方法について鋭意検討した結果、自動配合機で配合された粒状配合肥料を、自動袋詰装置でマイクロパーフォレーション包装袋に充填し、充填口をシールし、次いで製品表示をラベル化して貼付し、次いでホットメルト接着剤を塗布した後、パレット上に段積みすれば、少量多品種の粒状配合肥料を効率よく、且つ安価に荷造りすることができることを見出し、本発明を完成するに至った。 As a result of diligent research on the packing method of granular compound fertilizer, the present inventor filled the micro perforation packaging bag with the granular compound fertilizer compounded by the automatic compounding machine with an automatic bagging device, sealed the filling port, and then the product It is found that if a label is labeled and pasted, and then hot melt adhesive is applied and then stacked on a pallet, a small amount of various kinds of granular fertilizer can be packed efficiently and inexpensively. It came to complete.
すなわち本発明は、粒状配合肥料を袋詰してパレット上に段積みする粒状配合肥料の荷造り方法において、マイクロパーフォレーション包装袋を使用し、この包装袋に粒状配合肥料を充填し、充填口をシールし、次いでこの包装袋の上面で、四隅を除く部分に製品表示用ラベルを貼付し、次いでこの包装袋の上面の四隅にホットメルト接着剤を塗布した後、パレット上に段積みすることを特徴とする粒状配合肥料の荷造り方法である。 That is, the present invention relates to a packing method of granular compound fertilizer in which granular compound fertilizer is packed and stacked on a pallet, using a micro perforation packaging bag, filling the packing bag with the granular compound fertilizer, and sealing the filling port Then, on the upper surface of the packaging bag, product display labels are affixed to portions other than the four corners, and then hot melt adhesive is applied to the upper four corners of the packaging bag, and then stacked on a pallet. It is a packing method of granular compounded fertilizer.
本発明の方法は、マイクロパーフォレーション包装袋およびホットメルト接着剤を使用することによって、粒状配合肥料を充填した包装体の袋面を平坦化できるため、製品品種を表示した製品毎の専用の包装袋を使用することなく、製品表示用ラベルを容易に貼付することができ、ホットメルト接着剤の塗布面が僅かで済み、貼付ラベル上にまで塗布する必要が無く、貼付ラベルの印字の消去、滲み等を生じることがなく、パレット上に段積みした時に、段積み状態に偏りを生じることがなく、包装袋の保管、搬送が極めて良好である。従って、少量多品種の粒状配合肥料を効率よく、且つ安価に荷造りすることが可能となり、その産業上の利用価値は頗る大きい。 The method of the present invention can flatten the bag surface of the package body filled with the granular compound fertilizer by using the micro perforation packaging bag and the hot melt adhesive, so that the dedicated packaging bag for each product displaying the product type is displayed. The label for product display can be easily affixed without using the product, and the application surface of the hot-melt adhesive is small, and it is not necessary to apply it on the affixed label. When stacked on a pallet, there is no bias in the stacked state, and the packaging bag is very well stored and transported. Therefore, it becomes possible to pack a small amount of various kinds of granular compound fertilizer efficiently and inexpensively, and its industrial utility value is very large.
本発明において用いる粒状配合肥料は、樹脂等で粒状肥料表面を被覆した粒状被覆肥料と粒状肥料等を配合したものである。

粒状肥料等としては、植物栽培において養分を与えるために土壌に施される窒素、燐酸、加里、珪素、マグネシウム、カルシウム、マンガン、硼素等の種々の元素を含有する粒状物であり、具体例としては、尿素、硝酸アンモニウム、硝酸苦土アンモニウム、塩化アンモニウム、硫酸アンモニウム、硝酸ソーダ、硝酸カルシウム、硝酸加里、石灰窒素、ホルムアルデヒド加工尿素肥料（ＵＦ）、アセトアルデヒド加工尿素肥料（ＣＤＵ）、イソブチルアルデヒド加工尿素肥料（ＩＢＤＵ）、グアニール尿素（ＧＵ）等の窒素質肥料；燐酸アンモニウム、過燐酸石灰、重過燐酸石灰、熔成燐肥、腐植酸燐肥、焼成燐肥、重焼燐、苦土過燐酸、苦土燐酸等の燐酸質肥料；塩化加里、硫酸加里、燐酸加里等の加里質肥料；珪酸カルシウム等の珪酸質肥料；腐植酸マグネシウム、硫酸マグネシウム等のマグネシウム質肥料；生石灰、消石灰、炭酸カルシウム等のカルシウム質肥料；硫酸マンガン、硫酸苦土マンガン、鉱さいマンガン等のマンガン質肥料；硼酸、硼酸ソーダ等の硼酸質肥料、および／またはこれら粒状物の組合せによって得られる窒素―燐酸、窒素―加里、および燐酸―加里の２成分系、窒素―燐酸―加里の３成分系、あるいはこれらにマグネシウム、マンガン、硼素等の植物の生育に必要な要素を含有させた粒状肥料が挙げられる。 The granular fertilizer is a granular material containing various elements such as nitrogen, phosphoric acid, potassium, silicon, magnesium, calcium, manganese, boron, etc., which are applied to the soil to provide nutrients in plant cultivation. Is urea, ammonium nitrate, ammonium nitrate, ammonium chloride, ammonium sulfate, sodium nitrate, calcium nitrate, nitric acid potassium, lime nitrogen, formaldehyde processed urea fertilizer (UF), acetaldehyde processed urea fertilizer (CDU), isobutyraldehyde processed urea fertilizer ( Nitrogenous fertilizers such as IBDU) and guanneaurea (GU); ammonium phosphate, superphosphate lime, heavy superphosphate lime, molten phosphate fertilizer, humic phosphate fertilizer, calcined phosphorous fertilizer, heavy calcined phosphorus, bituminous phosphoric acid, bitter Phosphoric fertilizers such as soil phosphoric acid; potassium fertilizers such as potassium chloride, potassium sulfate, potassium phosphate; siliceous materials such as calcium silicate Fertilizers; Magnesium fertilizers such as magnesium humate and magnesium sulfate; Calcium fertilizers such as quick lime, slaked lime and calcium carbonate; Manganese fertilizers such as manganese sulfate, manganese sulfate sulfate and manganese; Borates such as boric acid and sodium borate Nitrogen-phosphoric acid, nitrogen-kari, and phosphoric acid-kari two-component systems, nitrogen-phosphoric acid-kali three-component systems obtained by fertilizers and / or combinations of these particulates, or magnesium, manganese, boron, etc. Examples include granular fertilizers containing elements necessary for plant growth.
粒状肥料および前記の粒状被覆肥料の粒径は特に限定はないが、製造上の観点から通常１〜１５ｍｍの範囲であり、好ましくは２〜５ｍｍの範囲である。 The particle size of the granular fertilizer and the granular coated fertilizer is not particularly limited, but is usually in the range of 1 to 15 mm, preferably in the range of 2 to 5 mm from the viewpoint of production.
本発明で使用されるマイクロパーフォレーション包装袋としては、市販のポリエチレン製またはポリプロピレン製のマイクロパーフォレーション包装袋を使用することができる。中でも特に、ポリエチレン製で袋の右端または左端の何れか一方から約０．５〜２ｃｍ幅の範囲で、その表裏に、横方向に約２〜４箇所、縦方向に約５〜１０ｍｍの間隔で直径が約０．０２〜０．１ｍｍの微細孔を有するマイクロパーフォレーション包装袋が好ましい。この範囲を超えて微細孔面積を増やす場合は、袋の強度が低下するため、荷降ろし等の衝撃により破袋が起こり易くなり好ましくなく、他方減らす場合は、従来のノーピン袋に近づくため、袋内の空気量を適度に調整することが困難となり、このため前記記載のようにラベル貼付およびパレット上に段積みする際に不備を来たすので好ましくない。 As the microperforation packaging bag used in the present invention, a commercially available microperforation packaging bag made of polyethylene or polypropylene can be used. In particular, it is made of polyethylene and has a width of about 0.5 to 2 cm from either the right end or the left end of the bag, on the front and back sides thereof at intervals of about 2 to 4 in the horizontal direction and about 5 to 10 mm in the vertical direction. A microperforation packaging bag having micropores with a diameter of about 0.02 to 0.1 mm is preferred. When the micropore area is increased beyond this range, the strength of the bag is reduced, so it is not preferable because bag breakage is likely to occur due to an impact such as unloading. It is difficult to appropriately adjust the amount of air in the interior, which is not preferable because it causes deficiencies when labeling and stacking on a pallet as described above.
本発明の製品表示用ラベルの貼付は、市販のラベラー（自動ラベル貼付機）をそのまま使用することができる。中でも特に、印字機能を持ったラベラーが好ましい。このようなラベラーを用いれば、例えば対象植物が同じものであれば包装袋の切替え等は必要なく、予め登録した製品別の品名と保証票を呼び出してラベル紙に印字し貼付させる方法で行なえば極めて効率的となる。 For labeling of the product display label of the present invention, a commercially available labeler (automatic labeling machine) can be used as it is. Of these, a labeler having a printing function is particularly preferable. If such a labeler is used, for example, if the target plant is the same, there is no need to switch the packaging bag, etc., if the name and warranty card for each product registered in advance is called and printed on the label paper and pasted. It becomes extremely efficient.
ホットメルト接着剤の塗布は、市販のホットメルト接着剤およびホットメルト塗布機をそのまま使用することができる。
ホットメルト接着剤としては、低密度ポリエチレン、エチレン−酢酸ビニル共重合体、ポリ塩化ビニル等が挙げられる。中でも特に軟化点が７０〜１１０℃のエチレン−酢酸ビニル共重合体が用いられる。これらは、軟化点に応じて予め１２０〜１８０℃程度に加熱溶融し、点または線状に塗布される。軟化点が該範囲を超えて高い場合は、溶融温度も高くなるため、塗布面のポリエチレン包装袋を溶融させ傷または穴を生じさせるため好ましくない。軟化点が低い場合は、接着力が弱くなるため塗布面積が大きくなり、ラベルの汚れ等を生じさせるので好ましくない。
また、一箇所当りの塗布量は０．０２〜０．１ｇの範囲で行なわれる。塗布量が該範囲を超えて多い場合は、接着面が大きくなるため、貼付ラベルの汚れ、荷降ろしまたは荷外しの際に包装袋の破損が生じ易くなるため好ましくない。一方、少ない場合は、接着力が充分でないため、パレット上に段積みする時またはパレット輸送時に荷崩れを生じ易くなるため好ましくない。
Application | coating of a hot-melt-adhesive can use a commercially available hot-melt-adhesive and a hot-melt applicator as it is.
Examples of the hot melt adhesive include low density polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride and the like. Among these, an ethylene-vinyl acetate copolymer having a softening point of 70 to 110 ° C. is particularly used. These are heated and melted in advance to about 120 to 180 ° C. according to the softening point, and are applied in the form of dots or lines. When the softening point is higher than the above range, the melting temperature becomes high, which is not preferable because the polyethylene packaging bag on the coated surface is melted to cause scratches or holes. When the softening point is low, the adhesive force is weakened, so that the coating area is increased and the label is soiled.
Moreover, the coating amount per location is in the range of 0.02 to 0.1 g. If the coating amount exceeds the above range, the adhesive surface becomes large, which is not preferable because the label is easily soiled, unloaded or unloaded from the packaging bag. On the other hand, when the amount is small, the adhesive force is not sufficient, and it is not preferable because the load collapses easily when stacking on the pallet or when transporting the pallet.
本発明において、自動配合機を使用して配合された上記の粒状配合肥料を上記のマイクロパーフォレーション包装袋に、通常、自動袋詰装置を使用して充填する。粒状配合肥料が充填された包装袋は、必要により脱気した後、充填口をシールする。通常、その後、重量を測定し、所定量充填されたことを確認する。 In the present invention, the above-mentioned granular compounded fertilizer compounded using an automatic compounding machine is usually filled into the above-mentioned micro perforation packaging bag using an automatic bagging device. The packaging bag filled with the granular compound fertilizer is deaerated as necessary, and then the filling port is sealed. Usually, after that, the weight is measured to confirm that a predetermined amount is filled.
粒状配合肥料が充填され、シールされた包装袋は倒され、上面をローラーで押し付けることによって、更には振動させることによって平坦化される。マイクロパーフォレーション包装袋を使用しているために、適度に袋内の空気量が調整され、脱気過多または脱気過少の状態を呈せず、袋面が充分な平面を保つため、ラベルを容易に貼付することが可能になる。
従来のノーピン包装袋を使用した場合には、充填、シールされた包装袋が脱気過多または脱気過少の時は、包装袋の面が内部の肥料と圧着または膨潤してラベルをうまく貼付するのに充分な平面を保てず、ラベルを容易に貼付することが困難となる。平坦化された包装袋とするために少量の空間を作るように脱気調整する必要があるが、製品の種類毎の粒径分布、嵩密度や、季節よって微妙に調整する必要があり、標準化が難しく、多品種の粒状配合肥料の充填には好ましくない。
The packaged bag filled with granular compounded fertilizer and sealed is laid down and flattened by pressing the upper surface with a roller and further vibrating. Since the micro perforation packaging bag is used, the amount of air in the bag is adjusted moderately, it does not exhibit excessive deaeration or excessive deaeration, and the bag surface keeps a sufficiently flat surface, making it easy to label It becomes possible to affix to.
When a conventional no-pin packaging bag is used, if the filled and sealed packaging bag is excessively degassed or degassed, the surface of the packaging bag is pressed or swelled with the fertilizer inside, and the label is successfully applied. However, it is difficult to keep a flat surface sufficient for this, and it is difficult to attach a label easily. It is necessary to adjust the deaeration so as to create a small amount of space in order to make a flattened packaging bag, but it is necessary to adjust it finely according to the particle size distribution, bulk density, and season for each product type. Is difficult and is not preferable for filling a variety of granular fertilizers.
次に、ホットメルト接着剤を塗布する上面の四隅を除く部分に製品表示用ラベルを上記方法によって貼付する。塗布する位置は、通常、包装袋の上面の中央部であるが、これに限らない。製品表示用ラベルとして、少なくとも品名ラベルと保証票ラベルを貼付する。 Next, a product display label is applied to the portion excluding the four corners of the upper surface to which the hot melt adhesive is applied by the above method. The application position is usually the central portion of the upper surface of the packaging bag, but is not limited thereto. At least a product name label and a warranty card label are affixed as product display labels.
次に、包装袋の上面の四隅に、上記の方法でホットメルト接着剤を塗布し、通常、自動パレタイズ機を用いてパレット上に段積みする。
ホットメルト接着剤は接着力が極めて高く、塗布面が僅かで済むことから貼付ラベル上にまで塗布する必要が無いため、貼付ラベルの印字の消去、滲み等を生じることは無い。
更に短時間（約５〜１０分）で完全に乾燥するので、その後の揺れ動きに対しても包装袋間のズレが起こり難い。また、上記の方法で塗布したホットメルト接着剤の場合、荷外しの時に、剥がし跡も綺麗である。
一方、従来の水性接着剤で塗布してパレタイズする場合は、水性接着剤は接着力が弱いため塗布面積を多く必要とし、パレタイズ時の荷崩れを起こさないためには袋面の中央部に、１／２〜１／５面に相当する範囲を塗布する必要がある。このため、貼付ラベル上にも水性接着剤が塗布されることとなり、貼付ラベルの印字の消去、滲み等が生じると共に、パレタイズ後の荷降ろしの際には、貼付ラベルの印字部の剥がれ等が起こり商品価値を低下させることがあり、好ましくない。更に完全に乾燥するのに長時間（約１２時間）を要し、その後の揺れ動きに対して包装袋間のズレが起こし易く、好ましくない。
Next, the hot-melt adhesive is applied to the four corners of the upper surface of the packaging bag by the above method, and usually stacked on a pallet using an automatic palletizing machine.
Since the hot melt adhesive has extremely high adhesive force and requires only a small coating surface, it does not need to be applied even on the adhesive label, and therefore does not cause erasure or bleeding of the adhesive label.
Furthermore, since it dries completely in a short time (about 5 to 10 minutes), the displacement between the packaging bags is less likely to occur with respect to the subsequent shaking movement. Further, in the case of the hot melt adhesive applied by the above method, the peeling mark is beautiful when unloaded.
On the other hand, when applying and palletizing with a conventional water-based adhesive, the water-based adhesive requires a large application area because the adhesive strength is weak, and in order to prevent the collapse of the load during palletizing, in the center of the bag surface, It is necessary to apply a range corresponding to 1/2 to 1/5 surface. For this reason, the water-based adhesive is also applied to the sticky label, which causes erasure and bleeding of the sticky label printing, and peeling of the print part of the sticky label when unloading after palletizing. It may occur and reduce the value of goods, which is not preferable. Furthermore, it takes a long time (about 12 hours) to dry completely, and a gap between the packaging bags tends to occur with respect to the subsequent shaking movement, which is not preferable.
本発明では、パレタイズ時において、マイクロパーフォレーション包装袋を用いているため、適度に袋内の空気量が調整され、段積み状態に偏りを生じることがなく、段積みした包装袋の保管が極めて良好である。 In the present invention, since micro perforation packaging bags are used at the time of palletizing, the amount of air in the bags is appropriately adjusted, and there is no bias in the stacked state, and storage of stacked packaging bags is extremely good. It is.
本発明においては、ラベルを貼付して品名、保証票を表示するため、製品の種類毎に専用の包装袋を用意しなくともよく、包装袋版代が少なくて済むと共に管理の手間が少なくなる。
従って、最近、より省力型として要求されている、各種植物の地域別および土壌種別の生育期間に合わせて肥効を持続させるようにした少量多品種の粒状配合肥料を効率よく、且つ安価に荷造りすることが可能となり、その産業上の利用価値は頗る大きい。
In the present invention, since the label is attached and the product name and the warranty card are displayed, it is not necessary to prepare a dedicated packaging bag for each type of product, the packaging bag plate cost can be reduced and the management effort is reduced. .
Therefore, the low-volume, multi-variety granular compound fertilizer, which has recently been required as a labor-saving type, and maintains the fertilization effect according to the growth period of various plants by region and soil type, is packed efficiently and inexpensively. And its industrial utility value is tremendous.
以下に実施例を挙げて本発明をさらに具体的に説明するが、本発明はこれら実施例によって何ら限定されるものではない。
なお、実施例中の部および％は特記しない限りすべて重量部および重量百分率を示す。
EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.
In addition, unless otherwise indicated, all the parts and% in an Example show a weight part and a weight percentage.
実施例１
対象植物が水稲コシヒカリで、地域別および土壌種別に異なる１０種類の粒状配合肥料を各３トンづつ以下に示す方法で荷造りした。
配合能力が１０トン／時間の自動配合機を使用して配合された粒状配合肥料を、袋詰能力が２０ｋｇ入り袋で５００袋／時間の自動袋詰装置を使用して、水稲コシヒカリ専用のマイクロパーフォレーション包装袋（袋面の右端に０．８ｃｍ幅の表裏の全面積に、横方向２箇所、縦方向８ｍｍの間隔で直径０．０２〜０．１ｍｍの微細孔を有する、厚さ１５０μｍで幅４３０ｍｍ×長さ６８０ｍｍのポリエチレン製袋）に充填し、充填口をシールした。
次いでこの包装袋の上面の中央部に印字機能を持ったラベラーで、予め登録した製品別の保証票と品名をラベル紙に印字貼付し、次いでこの包装袋の上面の四隅に、軟化点が約９５℃のエチレン−酢酸ビニル共重合体からなるホットメルト接着剤を自動ホットメルト塗布機で約１７０℃に加熱溶融し、一箇所当り約０．０５ｇを塗布した後、自動パレタイズ機で、１ｍ角の２台のパレット上にそれぞれ６袋（面方向）×１０袋（高さ方向）の６０袋（約１．２トン）を、１台のパレット上に６袋×５袋の３０袋（約０．６トン）を段積みし、これらを３段積み重ねて（合計１５０袋、約３トン）、保管した。
１０種類の粒状配合肥料の荷造り（合計１５００袋、約３０トン）に要した時間は約５時間であった。
このようにして得たパレット３段積み保管品の荷姿は、製品を充填したマイクロパーフォレーション包装袋が、段積みの加重に合わせて適度に脱気を行なうことから、傾きが全く無く、またホットメルト接着剤が袋間を充分に接着することにより、袋間のズレも全く見られず、極めて安定であった。次いで、１ヶ月後に観察したが、荷姿に変化は見られなかった。次いで、このものをトラックでバラ積みする際の荷外しの状態を観察した。荷外しは接着面が極めて少ないため剥れ易く、且つラベルの剥れおよびラベルの汚れ等も無く極めて良好であった。
Example 1
The target plant was paddy rice Koshihikari, and 10 types of granular fertilizers differing by region and soil type were packed by 3 tons each by the method shown below.
Granular fertilizer compounded using an automatic compounding machine with a compounding capacity of 10 tons / hour, and a micro-dedicated paddy rice for Koshihikari using an automatic bagging device with a bag capacity of 20 kg and 500 bags / hour Perforation packaging bag (having micropores with a diameter of 0.02 to 0.1 mm at intervals of 8 mm in the horizontal direction on the entire front and back area of 0.8 cm width at the right end of the bag surface, with a thickness of 150 μm and a width of 150 μm 430 mm × length 680 mm polyethylene bag) and the filling port was sealed.
Next, with a labeler that has a printing function in the center of the top surface of the packaging bag, a pre-registered product-specific warranty card and product name are printed and affixed to the label paper, and then the softening points at the four corners of the top surface of the packaging bag are approximately A hot melt adhesive composed of an ethylene-vinyl acetate copolymer at 95 ° C. is heated and melted to about 170 ° C. with an automatic hot melt coating machine, and after applying about 0.05 g per location, it is 1 m square with an automatic palletizing machine. 60 bags (about 1.2 tons) of 6 bags (surface direction) x 10 bags (height direction) each on 2 pallets, and 30 bags of 6 bags x 5 bags (about 1 bag) 0.6 tons) were stacked, and these were stacked in three stages (total 150 bags, about 3 tons) and stored.
The time required for packing 10 kinds of granular compound fertilizer (total 1500 bags, about 30 tons) was about 5 hours.
The packaging of the pallet three-stage storage product obtained in this way has no inclination at all because the micro perforation packaging bag filled with the product deaerates appropriately according to the weight of the stack. When the melt adhesive sufficiently adhered between the bags, there was no shift between the bags, and it was extremely stable. Then, after one month of observation, there was no change in the packing form. Next, the state of unloading when this was unloaded on a truck was observed. Unloading was very good because it had very few adhesive surfaces and was easy to peel off, and there was no label peeling or label contamination.
比較例１
対象植物が水稲コシヒカリで、地域別および土壌種別に異なる１０種類の配合肥料を各３トンづつ以下に示す従来の方法で荷造りした。
配合能力が１０トン／時間の自動配合機を使用して配合された粒状配合肥料を、袋詰能力が２０ｋｇ入り袋で５００袋／時間の自動袋詰装置を使用して、種類毎に専用のノーピン包装袋（細孔の無い厚さ１５０μｍで幅４３０ｍｍ×長さ６８０ｍｍのポリエチレン製袋）に充填し、充填口をシールし、次いでこの包装袋の上面の１／３面に相当する範囲に、融点が約０℃のエチレン−酢酸ビニル共重合体水性エマルジョンを自動水性エマルジョン塗布機で約２０℃で約０．３ｇを塗布した後、自動パレタイズ機で、実施例１と同様にパレット上に段積みした。
荷造りに要した時間は実施例１と同じ約５時間であった。
このようにして得たパレット３段積み保管品の荷姿は、製品を充填したノーピン包装袋が、段積みの加重に合わせて適度に脱気を行なうことができないことから、傾きが大きく、また水性接着剤が袋間を充分に接着するに時間を要することから、袋間のズレも多く見られ、不安定であった。次いで、１ヶ月後に観察したが、荷姿は不安定のままであった。次いで、このものをトラックでバラ積みする際の荷外しの状態を観察した。荷外しは接着面が大きいため剥れ難く、且つ接着面の印字の剥れおよび印字の汚れ等も目立ち、商品価値を大きく損なうものであった。
Comparative Example 1
The target plant was paddy rice Koshihikari, and 10 kinds of mixed fertilizers differing by region and soil type were packed by the conventional method shown below by 3 tons each.
A granular compound fertilizer compounded using an automatic compounding machine with a compounding capacity of 10 tons / hour is dedicated to each type using an automatic bagging machine with a bag capacity of 20 kg and 500 bags / hour. Filled into a no-pin packaging bag (polyethylene bag having a thickness of 150 μm without pores and a width of 430 mm and a length of 680 mm), sealing the filling port, and then in a range corresponding to 1/3 of the upper surface of the packaging bag, After applying about 0.3 g of an ethylene-vinyl acetate copolymer aqueous emulsion having a melting point of about 0 ° C. at about 20 ° C. with an automatic aqueous emulsion applicator, it was placed on a pallet with an automatic palletizing machine in the same manner as in Example 1. Piled up.
The time required for packing was about 5 hours as in Example 1.
The packaging of the pallet three-stage storage product obtained in this way has a large inclination because the no-pin packaging bag filled with the product cannot be appropriately deaerated according to the weight of the stack. Since it took time for the water-based adhesive to sufficiently bond the bags, there was a lot of displacement between the bags, which was unstable. Next, it was observed one month later, but the package remained unstable. Next, the state of unloading when this was unloaded on a truck was observed. The unloading is difficult to peel off because of the large adhesive surface, and the printed surface of the adhesive surface and the stain on the printed image are conspicuous, and the commercial value is greatly impaired.
