Description

この発明は、ダンボールの表面に多数の粒状ホットメルトを溶融接着させ、固化後のホットメルト突起を利用したダンボール表面の滑り止め加工と、粒状ホットメルトを再加熱しダンボール同士を接着する方法に関するものである。 The present invention relates to a method for melt-bonding a large number of granular hot melts on the surface of cardboard, anti-slip processing of the cardboard surface using hot melt protrusions after solidification, and a method for reheating the granular hot melt and bonding the cardboards together. It is.

ダンボールの滑り止め加工について
従来、ダンボール表面の滑り止め加工はほとんど無く、一部に箱に成形されたダンボールの天面にホットメルトガンを使用し、ホットメルトを数ｃｍ接着固化させた滑り止め加工がある。 Non-slip processing of corrugated cardboard Conventionally, there is almost no anti-slip processing on the surface of the corrugated cardboard, and a hot melt gun is used on the top of the corrugated cardboard partly molded into a box, and the hot melt is bonded and solidified several cm. There is.

ダンボールの接着方法について
従来、ダンボールを箱に成形するためには、専用のホットメルトガンで接着面に溶融させたホットメルトを出し、両面を張り合わせることにより接着させるか粘着テープを接合部に貼付し、箱に成形している。 Conventionally, in order to form corrugated cardboard into a box, hot melt melted on the adhesive surface with a special hot melt gun and bonded by sticking both sides or sticking adhesive tape on the joint And molded into a box.

ダンボールの滑り止め加工について
従来技術は、ダンボール箱の天面にホットメルトの突起を成形し滑り止めとしているが、
１、積み重ねる相手ダンボールの底面には滑り止め加工がされていないため、滑り止め加工としてはあまり効果を発揮していない。
２、ダンボール箱の側面は何ら滑り止め加工をしていないため、輸送途上でダンボールが滑り、荷崩れの原因となっている。 Regarding the anti-slip processing of cardboard, the conventional technology forms a hot melt protrusion on the top surface of the cardboard box to prevent it from slipping.
1. Since the bottom surface of the mating corrugated cardboard is not slip-resistant, it is not very effective as a slip-proof.
2. Since the side surface of the cardboard box is not slip-proofed at all, the cardboard slips during transportation, causing the collapse of the cargo.

ダンボールの接着方法について
従来技術は、ホットメルトガンや、粘着テープを使用し接着しているが、
ホットメルトガンの場合は、
１、接着面がダンボールの一部のみであり、接着強度を上げるため多量のホットメルトが必要であった。また、垂直面の接着では液だれが問題だった。
２、ダンボール面の接着作業時間については、ホットメルトガンから出た溶融したホットメルトが固化するまでの数秒しか余裕が無く、作業に熟練を必要としていた。
粘着テープを使用した場合は、
多くの粘着テープが必要になり、
ダンボール上の文字、又は図形が粘着テープにより隠れてしまうことが多かった。 Regarding the bonding method of cardboard, the conventional technology uses a hot melt gun or adhesive tape to bond,
For hot melt guns,
1. The adhesive surface is only a part of the cardboard, and a large amount of hot melt is required to increase the adhesive strength. In addition, dripping was a problem when bonding vertical surfaces.
2. Regarding the bonding work time of the corrugated cardboard surface, there was only a few seconds until the molten hot melt from the hot melt gun solidified, and skill was required for the work.
When using adhesive tape,
A lot of adhesive tape is needed,
The characters or figures on the cardboard were often hidden by the adhesive tape.

箱に成形する前の展開状態のダンボール表面の全部または一部に、粒状のホットメルトを多数融解接着させた粒状突起をあらかじめ形成しておく。
１、ダンボールの滑り止め加工について
上記加工を施したダンボールを箱に成形すると、ダンボールの天面、底面、側面に突起が形成された箱が出来上がり、また同加工を施されたダンボールを積み重ね並べた場合、相接触した粒状突起がダンボール箱の表面の滑り止めとして効果を発揮する。
２、ダンボールの接着方法について
ダンボールを接着する場合、接着面をヒーターで加熱し、粒状ホットメルトを再溶融させ両面を接着させる。 Granular protrusions in which a large number of granular hot melts are melt-bonded are formed in advance on all or part of the surface of the corrugated cardboard before being formed into a box.
1. Anti-slip processing of corrugated cardboard When the corrugated cardboard subjected to the above processing is formed into a box, a box with protrusions formed on the top, bottom and side surfaces of the corrugated cardboard is completed, and the corrugated cardboard subjected to the same processing is stacked and arranged. In this case, the phase-contacted granular protrusions are effective as a slip stopper on the surface of the cardboard box.
2. Bonding method for corrugated cardboard When corrugated cardboard is bonded, the bonded surface is heated with a heater to remelt the granular hot melt to bond both surfaces.

ダンボールの滑り止め加工について
箱に形成されたダンボールの各面は，ゴム状の粒状ホットメルトの突起により、同様に加工されたダンボールを積み重ね、並べた場合，相接する面の滑り止めとして効果を発揮し、荷崩れの防止に寄与する。
また、ダンボール箱の天面、底面、側面の一部を加熱し、ダンボール箱同士を接着させればより荷崩れが防止され、運送業で使用されている荷崩れ防止用のシュリンク等の削減に効果を発揮する。
ダンボール取り扱い時にも、手との摩擦を高め、ダンボール製品の落下を防止できる。 Anti-slip processing of corrugated cardboard Each side of the corrugated cardboard formed on the box is made of rubber-like granular hot-melt protrusions, and when processed in the same way, the cardboard is effective as an anti-slip surface. Demonstrate and contribute to prevention of cargo collapse.
Also, if the top, bottom, and part of the cardboard boxes are heated and bonded together, the cardboard boxes can be prevented from collapsing more, reducing the amount of shrinkage and other shrinkage used in the transportation industry. Demonstrate the effect.
Even when handling corrugated cardboard, it can increase the friction with the hand and prevent the cardboard product from falling.

ダンボールの接着方法について
ホットメルトガンを使用した接着に比べ、接着面が糊代表面全体におよび、接着強度を増すと同時に、ホットメルトの節約に繋がる。
ヒーターによる粒状ホットメルトの再加熱は何回でも実施できるため、作業時間に余裕ができ、熟練を必要としなくなる。また、ホットメルトガンによる工程を省略できるため、組立作業を範略化することができる。また、粘着テープが必要なくなり、経費の削減に寄与する。
垂直面の接着でも液だれが発生せず、きれいに仕上げることができる。 Compared to the bonding using a hot melt gun for the cardboard bonding method, the bonding surface covers the entire glue representative surface, and at the same time, the bonding strength is increased, and at the same time, the hot melt is saved.
Since the granular hot melt can be reheated with a heater any number of times, the working time can be afforded and skill is not required. Moreover, since the process by a hot melt gun can be omitted, assembly work can be simplified. In addition, an adhesive tape is not necessary, which contributes to cost reduction.
Even if the vertical surface is bonded, dripping does not occur, and it can be finished neatly.

粒状突起の形状について
ダンボール上の粒状突起の形状は、接着剤塗布の形により、点、面、線、文字、マーク等、自由に設計できる。 Regarding the shape of the granular protrusions The shape of the granular protrusions on the cardboard can be freely designed as dots, surfaces, lines, characters, marks, etc., depending on the shape of the adhesive application.

Excess granular hot melt that has not contacted the adhesive is removed from the cardboard.
In order to strengthen the adhesion between the corrugated cardboard surface and the granular hot melt, the surface is again heated from 100 ° C. to 200 ° C. by the heater (4), the granular hot melt is melted and adhered to the corrugated cardboard surface, and the adhesive strength is increased. .
3. The corrugated cardboard surface to which the granular hot melt is bonded returns to room temperature, and hot melt protrusions (5) are formed, which is effective as a rubber-like anti-slip.
4. To form a corrugated cardboard in a box, the granular hot melt protrusions formed in the adhesive margin are reheated by a heater, and when the granular hot melt is melted, both adhesive surfaces are pressure-bonded to bond both surfaces.
