Description

本発明は、ダンボールに関するものであって、その表面からの紙粉の発生を抑止したダンボール、およびこのダンボールを用いた収納体に関する。   The present invention relates to a corrugated cardboard, and relates to a corrugated cardboard in which generation of paper dust from the surface thereof is suppressed, and a container using the corrugated cardboard.

従来、工業用部品あるいは機器、治具等を輸送するときに、これらの輸送物の破損、傷付き等を防止する為にダンボール製の収納体が用いられることがある。このダンボール製の収納体は、輸送物の形状に合わせて、外箱の中に適宜仕切材を組み込んで輸送物を固定するように構成される。   Conventionally, when transporting industrial parts, equipment, jigs, or the like, cardboard containers are sometimes used to prevent breakage, damage, etc. of these transported items. The container made of cardboard is configured so as to fix the package by appropriately incorporating a partition material in the outer box in accordance with the shape of the package.

陸路等での輸送中には、収納体に振動が加わることになる。輸送物の固定は完全ではないため、輸送中に輸送物と収納体のダンボールが擦れ合ってダンボールから紙粉が発生することになる。従って、輸送完了後に輸送物を取り出して使用するときは、輸送物に付着した紙粉を取り除く作業が必要になっていた。   During transportation on land or the like, vibration is applied to the storage body. Since the transported item is not completely fixed, the transported product and the corrugated cardboard of the storage body rub against each other during the transport, and paper dust is generated from the cardboard. Therefore, when the transported goods are taken out and used after the transportation is completed, it is necessary to remove the paper dust adhering to the transported goods.

そこで、輸送中のダンボールからの紙粉の発生を防止するための梱包材が提案されている。   Therefore, a packaging material has been proposed for preventing the generation of paper dust from the cardboard during transportation.

この梱包材では、箱体に緩衝材を組み込むことで、箱体に収納される製品が箱体天面と直接接触しないようにすることで天面からの紙粉の発生を防止している。しかしながら、底面側については、緩衝材と製品とが緊密に固定されているため搬送時に両者が擦れ合うことは本来的に生じにくい、として何ら考慮されていない。   In this packing material, the generation of paper powder from the top surface is prevented by incorporating a cushioning material into the box so that the product stored in the box does not directly contact the top surface of the box. However, no consideration is given to the bottom surface side because the shock-absorbing material and the product are tightly fixed, so that they hardly rub against each other during transportation.

JP 2005-96786 A

しかし、実際には底面側についても、緩衝材と製品とが緊密に固定されているとは限らず、また、搬送方法等により両者が擦れ合うことが皆無ではなく、実際には底面側から発生した輸送物に付着した紙粉を取り除く作業が必要になっていた。   However, in fact, the cushioning material and the product are not always tightly fixed on the bottom side, and there is no possibility that they will rub against each other depending on the transport method, etc. It was necessary to remove the paper dust adhering to the package.

本発明は、紙粉の発生という問題を解決するためになされたもので、輸送物と擦れ合っても紙粉が発生するのを抑止するこのとのできるダンボール、このダンボールを用いた収納体を提供することを課題とする。   The present invention has been made to solve the problem of the generation of paper dust. A cardboard capable of suppressing the generation of paper dust even when rubbing against a transported article, and a container using the cardboard are provided. The issue is to provide.

上記課題を解決するため、請求項1記載の発明は、表面に水性ワニスが塗布されたことを特徴とする紙粉の発生を防止したダンボールを提供するものである。   In order to solve the above-mentioned problems, the invention described in claim 1 provides a corrugated cardboard which prevents the generation of paper dust, characterized in that an aqueous varnish is applied to the surface.

請求項2記載の発明は、表面にグラビア印刷法により水性ワニスが塗布されたことを特徴とする紙粉の発生を抑止したダンボールを提供するものである。   The invention described in claim 2 provides a corrugated cardboard which suppresses the generation of paper dust, characterized in that an aqueous varnish is applied to the surface by a gravure printing method.

請求項3記載の発明は、表面にグラビア印刷法により水性ワニスが塗布されたライナーを用いて製造されたことを特徴とする紙粉の発生を抑止したダンボールを提供するものである。   The invention according to claim 3 provides a corrugated cardboard which suppresses the generation of paper dust, which is manufactured using a liner having a surface coated with an aqueous varnish by a gravure printing method.

請求項4記載の発明は、請求項1、2または3のいずれかに記載のダンボールの水性ワニスが塗布された面が、収納物に接するように形成されたことを特徴とする紙粉の発生を抑止したダンボールを用いた収納体を提供するものである。   The invention according to claim 4 is characterized in that the surface of the corrugated cardboard according to claim 1, 2 or 3 is formed so as to be in contact with the stored item. It is intended to provide a storage body using cardboard that suppresses the above.

本発明によれば、輸送物と擦れ合っても、ダンボールから紙粉が発生するのを抑止できる。また、輸送物に施された表面加工に影響を与えることがない。具体的には、輸送物に塗布されたインキ剥がれがほとんどなかった。   According to the present invention, it is possible to prevent paper dust from being generated from corrugated cardboard even when it is rubbed with a transported item. Moreover, it does not affect the surface processing applied to the transported goods. Specifically, there was almost no ink peeling applied to the transported material.

また、従来のダンボール製の収納体と比較して、製造コストをほぼ同等にすることができるので、結局コストアップを抑えられるという独自の効果がある。   In addition, since the manufacturing cost can be made substantially equal to that of a conventional cardboard storage body, there is an original effect that an increase in cost can be suppressed after all.

以下、図面に基づいて本発明の実施形態を説明する。図1は本発明における実施の形態の一実施形態を説明するための斜視図である。まず、ダンボールは原則として3枚の板紙から構成され、平板状の表ライナー11と、同じく裏ライナー12と、両ライナー11、12に挟まれた波打ち加工(コルゲート加工)された中芯13とからなっており、両ライナー11、12は中芯13の頂点部でおのおの接着剤14により接着されている。さらに、表ライナー11の外面に水性ワニスが塗布され、ワニス層21が形成されているものである。このときの水性ワニスは、輸送物と直接接触することとなる表ライナーのみにに塗布され、ワニス層が形成されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view for explaining an embodiment of the present invention. First, the cardboard is basically composed of three paperboards, and includes a flat front liner 11, a back liner 12, and a corrugated core 13 sandwiched between both liners 11 and 12. Both liners 11 and 12 are bonded to each other by an adhesive 14 at the apex of the core 13. Further, an aqueous varnish is applied to the outer surface of the front liner 11 to form a varnish layer 21. The aqueous varnish at this time is applied only to the front liner that will be in direct contact with the transported material to form a varnish layer.

この様なダンボールの製造方法の例としては、まず、ダンボールの上下面を構成する表ライナーおよび裏ライナーの各々の外面に水性ワニスを塗布するにあたっては、ロール状ライナーに、グラビア印刷方式で水性ワニスを塗布(印刷)し巻き取るいわゆるロールtoロール方式でワニス層を形成する。この場合、オフセット印刷方式や、フレキソインキを用いる方法もあるが、コスト的に高くなりがちで好ましくはない。   As an example of such a corrugated cardboard manufacturing method, first, when applying an aqueous varnish to the outer surfaces of the front and back liners constituting the upper and lower surfaces of the corrugated cardboard, the aqueous varnish is applied to the roll liner by a gravure printing method. The varnish layer is formed by a so-called roll-to-roll method that coats (prints) and winds. In this case, there are an offset printing method and a method using flexo ink, but this is not preferable because it tends to be expensive.

次に、この水性ワニスが塗布されたロール状ライナーを用いて、ダンボールを製造する。具体的には、中芯をコルゲート加工し、順次表ライナーと裏ライナーと接着剤で接着し、さらに断裁をする。   Next, corrugated cardboard is manufactured using the roll-shaped liner with which this aqueous varnish was apply | coated. Specifically, the core is corrugated, and the front liner and the back liner are sequentially adhered with an adhesive, and further cut.

最後に、このダンボールを用いて、収納体を作成する。   Finally, a container is created using this cardboard.

この製法によれば、水性ワニスを塗布することにより、製造コストを抑えることができた。なお、断裁後の板状になったダンボールに水性ワニスを塗布する方法では、製造コストがアップしてしまうので余り好ましくはない。   According to this production method, the production cost could be reduced by applying the aqueous varnish. Note that the method of applying the aqueous varnish to the corrugated cardboard after cutting is not preferable because the manufacturing cost increases.

この場合のダンボールは、JIS Z 1507に規定されている各種ダンボールの他、その他規格外であっても波型に成形した中芯とその片面または両面に板紙を貼り合わせた各種のものが用いられる。   In this case, the corrugated cardboard is not limited to various corrugated cardboards defined in JIS Z 1507, and other corrugated cardboard cores and various corrugated paperboards on one or both sides are used. .

また、水性ワニスは、樹脂のうち溶剤として水やアルコール等を用いることが可能なもので、樹脂と各種溶剤と水、場合により体質顔料の様な無色または白色の顔料等、その他各種調整材料からなっている水性ワニス溶液を塗布(印刷)し、水やアルコール等の溶剤を乾燥により飛ばしたものである。水性ワニスは、環境に配慮する意味で好ましい。   Water varnish is a resin that can use water, alcohol, etc. as a solvent, from resin, various solvents and water, and in some cases, other various adjustment materials such as colorless or white pigments such as extender pigments. The aqueous varnish solution is applied (printed), and a solvent such as water or alcohol is blown off by drying. The aqueous varnish is preferable in consideration of the environment.

水性ワニスのダンボール、特にライナーへの付与方法は、各種塗布装置、印刷装置などを使用でき、そのワニス層の形成方法を問うものでないが、ロールtoロール形式が連続
処理に適しているので安価に製造できる点で優れている。また、処理の容易性の点で、ダンボールをなしてから水性ワニスを付与するのではなく、ライナーに水性ワニスを付与してからダンボールにするのが安価に行える。また、塗布印刷方法のなかでグラビア印刷法が最も好ましい。
The application method to the corrugated cardboard of the aqueous varnish, particularly the liner, can use various coating devices, printing devices, etc., and does not ask the method of forming the varnish layer, but it is inexpensive because the roll-to-roll type is suitable for continuous processing. It is excellent in that it can be manufactured. Further, from the viewpoint of ease of processing, it is possible to inexpensively produce a corrugated cardboard after an aqueous varnish is applied to the liner, instead of providing a corrugated cardboard after the corrugated cardboard is formed. Of the coating printing methods, the gravure printing method is most preferable.

水性ワニスの一度刷り、二度刷りの二種を作成し、比較として普通芯ダンボール、強化芯ダンボールを含めて磨耗試験を実施した。   Two types of water varnishes were printed once and twice, and a wear test was conducted including normal core cardboard and reinforced core cardboard as a comparison.

ここで用いられた各ライナーは、クラフトライナーで、A級表示坪量210g/m2の材料を用いた(JIS P 3902による表示方法)。 Each liner used here was a craft liner, and a material having a class A display basis weight of 210 g / m 2 was used (display method according to JIS P 3902).

同様に、中芯は、セミケミカルパルプ(SCP)を原料とした中芯で、Aフルートのものを用いた。この場合の水性ワニスの一度刷り、二度刷りおよび普通芯ダンボールについては表示坪量120g/m2、強化芯ダンボールについては表示坪量180g/m2の材料の材料を用いた(JIS P 3902による表示方法)。 Similarly, the core was made of semi-chemical pulp (SCP) as a raw material, and the one with A flute was used. Once printing of the aqueous varnish in this case, by twice printing and plain core cardboard display basis weight 120 g / m 2 for reinforcing the core cardboard a material other display basis weight 180 g / m 2 material (JIS P 3902 Display method).

なお、Aフルートとは30cm当たりの段の数が34±2段であり、段の高さが4.5〜4.8mm、段ぐり率が1.6倍のものを指す。   In addition, A flute indicates the number of steps per 30 cm is 34 ± 2 steps, the step height is 4.5 to 4.8 mm, and the stepping rate is 1.6 times.

水性ワニスは、東洋インキ製造株式会社製、製品名:アクワエース BM OP ワニス(組成:合成樹脂20〜30重量%、エタノール5〜10重量%、メタノール1〜5重量%、イソプロピルアルコール5〜10重量%、水50〜10重量%のものを用い、グラビア版深:50μm、印刷スピード:100m/分の条件で、一度もしくは二度印刷を行った。   Water-based varnish is manufactured by Toyo Ink Manufacturing Co., Ltd., product name: AQUAACE BM OP varnish (composition: synthetic resin 20-30% by weight, ethanol 5-10% by weight, methanol 1-5% by weight, isopropyl alcohol 5-10% by weight Using 50 to 10% by weight water, printing was performed once or twice under the conditions of gravure plate depth: 50 μm and printing speed: 100 m / min.

この場合、一度刷りのときは、版深50μm内のほぼ全てのワニスがダンボールに転写された。二度刷りのときは、ダンボール表面が一度刷りのワニスが平滑になっているため、版深50μm中8割(40μm)程度がダンボールに転写される。   In this case, at the time of printing once, almost all varnish within the plate depth of 50 μm was transferred to the cardboard. When printing twice, since the varnish once printed on the surface of the cardboard is smooth, about 80% (40 μm) of the plate depth of 50 μm is transferred to the cardboard.

この結果得られた各ダンボールを摩耗試験した。具体的には、図2の様な装置で、電磁式振動試験機上に試作した摩耗試験装置を設置した。具体的には、振動方向36が定められている振動台32の上に測定対象であるダンボール31を載せ、その上に金属のプレス切断片33を通して固定枠35により確実に加重される構造の重錘34が荷重となる様になっている。これによれば、プレスで切断した金属切断片33の切断面をダンボール31と摩擦させ、摩耗量を電子はかりで測定した。振動条件は、振動数5Hz、振動加速度0.75G、振動時間10分とし、荷重を15〜113Nの範囲で変化させた。ダンボールは段の流れる水平方向に摩擦させた場合(以下M.D.と称する)と、段と交差する水平方向に摩擦させた場合(以下C.D.と称する)の両方を行った。結果は表1と表2に示す。   Each cardboard obtained as a result was subjected to an abrasion test. Specifically, a wear test apparatus made as a prototype on an electromagnetic vibration tester was installed with the apparatus shown in FIG. Specifically, a cardboard 31 to be measured is placed on a vibration table 32 in which a vibration direction 36 is defined, and a weight of a structure that is reliably loaded by a fixed frame 35 through a metal press cut piece 33 thereon. The weight 34 becomes a load. According to this, the cut surface of the metal cut piece 33 cut by the press was rubbed with the corrugated cardboard 31, and the amount of wear was measured with an electronic balance. The vibration conditions were a frequency of 5 Hz, a vibration acceleration of 0.75 G, a vibration time of 10 minutes, and the load was changed in the range of 15 to 113N. The corrugated cardboard was both rubbed in the horizontal direction in which the steps flow (hereinafter referred to as MD) and rubbed in the horizontal direction intersecting the steps (hereinafter referred to as CD). The results are shown in Tables 1 and 2.

それをグラフにすると、図3および図4の様になる。   If it is made into a graph, it will become like FIG. 3 and FIG.

また、収納状況での振動試験を行うため、ハブ包装品(8個入り)およびロータ包装品(10個入り)の振動試験を、正弦波対数掃引振動試験により行った。   In addition, in order to perform a vibration test in the storage state, vibration tests of the hub packaged product (with 8 pieces) and the rotor packaged product (with 10 pieces) were performed by a sine wave logarithmic sweep vibration test.

用意したハブ包装品はダンボールシートにより2列4段に区分けされ、ハブが8個収納されている状態であり外側寸法は370×230×150mmで総重量3.6kgであった。対してロータ包装品はダンボールシートにより2列5段に区分けされ、ロータが10個収納されている状態であり外側寸法は370×230×150mmで総重量10.4k
gであった。
The prepared hub package was divided into four rows and two rows by corrugated cardboard sheets, and 8 hubs were accommodated. The outer dimensions were 370 × 230 × 150 mm and the total weight was 3.6 kg. On the other hand, the rotor package is divided into two rows and five stages by corrugated cardboard sheets, and 10 rotors are accommodated. The outer dimensions are 370 × 230 × 150 mm and the total weight is 10.4 k.
g.

材質は、水性ワニスの一度刷り、二度刷りの二種のダンボールを作成し、比較として普通芯ダンボール、ミラーマット貼りダンボールを含めて振動試験を実施した。   As materials, two types of corrugated cardboard were printed once and then twice, and a vibration test was performed including normal core cardboard and corrugated cardboard with a mirror mat as a comparison.

試験は、振動数5〜50Hz、振動加速度0.75G、振動方向は上下(Z)、前後(X)、左右(Y)で、振動時間は1時間×3方向=計3時間(JIS輸送距離2000km以上相当)でおこなった。結果は、表3の通りであり、図5、6の通りであった。   The test is performed at a frequency of 5 to 50 Hz, vibration acceleration of 0.75 G, vibration direction is up and down (Z), front and rear (X), left and right (Y), vibration time is 1 hour × 3 direction = total 3 hours (JIS transport distance) (Equivalent to 2000 km or more). The results are as shown in Table 3 and are as shown in FIGS.

ハブ包装品の試験の結果、水性ワニスをオーバーコートした紙粉防止用ダンボールでは、普通芯ダンボールと比較して紙粉防止効果があまり見られなかった。上下方向の振動でライナ破れが発生したことが原因と考えられる。   As a result of the test of the hub package product, the paper dust preventing cardboard overcoated with the aqueous varnish did not show much paper dust preventing effect as compared with the normal core cardboard. This is probably because the liner was broken by vertical vibration.

ロータ包装品の試験の結果、普通芯ダンボールはロータ塗装がダンボールに付着した。紙粉防止用ダンボールでは紙粉発生はほとんど見られなかった。   As a result of testing the rotor package, the rotor core of the normal core cardboard adhered to the cardboard. In the cardboard for preventing paper dust, almost no paper dust was generated.

続いて、収納状況での振動試験を行うため、ロータ包装品(10個入り)の振動試験を、共振振動数が水性ワニス1度刷りの場合8Hz、水性ワニス2度刷りの場合8Hz、普通芯段ボールの場合8Hz、ミラーマット貼り段ボールの場合7Hzで、振動加速度0.75G、振動方向は前後(X)、振動時間15分で行った。この場合、図7の様に供試品の底面片側にダンボールを貼り付けて、10mm底上げした。   Subsequently, in order to conduct a vibration test in the storage state, the vibration test of the rotor packaged product (10 pieces) was carried out with a resonance frequency of 8 Hz when the aqueous varnish was printed once, 8 Hz when the aqueous varnish was printed twice, and a normal core. In the case of corrugated cardboard, it was 8 Hz, in the case of corrugated cardboard with a mirror mat, the vibration acceleration was 0.75 G, the vibration direction was front and rear (X), and the vibration time was 15 minutes. In this case, as shown in FIG. 7, a corrugated cardboard was affixed to one side of the bottom surface of the specimen, and the bottom was raised by 10 mm.

試験結果は、表4の通りであり、図8の通りであった。   The test results are as shown in Table 4 and as shown in FIG.

紙粉防止用ダンボールでは普通芯ダンボールより紙粉発生が少なく、紙粉防止用ダンボールの紙粉防止効果が認められた。   Paper dust-preventing cardboard produced less paper dust than ordinary core corrugated cardboard, and the paper dust-preventing cardboard was found to be effective in preventing paper dust.
