Description

本発明は、上下両面に対向配置された面材間に発泡性樹脂芯材が発泡成形されてなる帯状のサンドイッチパネルを製造するためのサンドイッチパネル製造設備及びサンドイッチパネル製造方法に関するものである。   The present invention relates to a sandwich panel manufacturing facility and a sandwich panel manufacturing method for manufacturing a strip-shaped sandwich panel in which a foamable resin core material is foam-molded between facing members disposed on both upper and lower surfaces.

帯状のサンドイッチパネルを製造する工程の一例は、下記特許文献１，２に開示されている。サンドイッチパネルは、例えば、硬質ポリウレタンフォームを可撓性を有する鋼板により形成された上面材と下面材によりサンドイッチした構造を有しており、建築用の断熱パネルなどとして利用されている。このサンドイッチパネルの製造工程においては、上面材を巻き付けたロールと、下面材を巻き付けたロールから、夫々ロールを引き出していき、これら面材間に硬質ポリウレタンフォーム（発泡性樹脂芯材に相当）を発泡させて成形する。かかるサンドイッチパネルは、帯状の形態で連続的に製造されていき、裁断装置により所定サイズのパネルとなるように裁断される。   An example of a process for producing a strip-shaped sandwich panel is disclosed in Patent Documents 1 and 2 below. The sandwich panel has, for example, a structure in which a rigid polyurethane foam is sandwiched between an upper surface material and a lower surface material formed of a flexible steel plate, and is used as a heat insulating panel for construction. In the manufacturing process of this sandwich panel, the rolls are drawn out from the roll around which the upper surface material is wound and the roll around which the lower surface material is wound, and a rigid polyurethane foam (corresponding to a foamable resin core material) is placed between these surface materials. Form by foaming. Such a sandwich panel is continuously manufactured in the form of a strip, and is cut into a panel of a predetermined size by a cutting device.

また、搬送される上面材と下面材の間に配置されたミキシングヘッドから発泡原液組成物を下面材の面上に吐出させ、その後、いわゆるダブルコンベア（発泡搬送部に相当）により帯状サンドイッチパネルの形態で搬送させながら発泡処理が行われる。   Also, the foaming stock solution composition is discharged onto the surface of the lower surface material from the mixing head arranged between the upper surface material and the lower surface material to be conveyed, and then the band-shaped sandwich panel is formed by a so-called double conveyor (corresponding to the foam conveying portion). Foaming is performed while being conveyed in the form.

このサンドイッチパネル製造で使用される鋼板製の上下面材は、保管時における耐錆性や耐傷性の目的で、両面に塗装が施されている。従って、発泡原液組成物もこのような塗装面に対して吐出されることになるが、ポリウレタンフォームとの密着性の点で問題があり、発泡処理時にボイドが発生するという問題がある。   The steel plate upper and lower surface materials used in this sandwich panel manufacture are coated on both sides for the purpose of rust resistance and scratch resistance during storage. Accordingly, the foamed stock solution composition is also discharged onto such a painted surface, but there is a problem in terms of adhesion to the polyurethane foam, and there is a problem that voids are generated during the foaming process.

かかる問題に対処するため、面材表面にコロナ放電処理を行うことで、ポリウレタンフォームとの密着性を改善することもできるが、発泡剤やフォーム性状の多様化に伴い、コロナ放電処理では対応できないケースも存在する。また、コロナ放電を行なうための装置は高価であるため、コストの面においても問題がある。   In order to deal with such problems, the corona discharge treatment can be performed on the surface of the face material to improve the adhesion to the polyurethane foam. Cases also exist. In addition, since an apparatus for performing corona discharge is expensive, there is a problem in terms of cost.

本発明は上記実情に鑑みてなされたものであり、その課題は、塗装が施された鋼板製の面材と発泡性樹脂芯材との密着性をコストを抑制しながら改善することが可能なサンドイッチパネル製造設備及びサンドイッチパネル製造方法を提供することである。   This invention is made | formed in view of the said situation, The subject is able to improve, suppressing cost, the adhesiveness of the surface material made from the coated steel plate, and a foaming resin core material. A sandwich panel manufacturing facility and a sandwich panel manufacturing method are provided.

本発明に係るサンドイッチパネル製造設備の好適な実施形態を図面を用いて説明する。図１は、サンドイッチパネル製造設備を模式的に示す側面図である。かかるサンドイッチパネルは、例えば、建築用の壁材として用いられる。   A preferred embodiment of a sandwich panel manufacturing facility according to the present invention will be described with reference to the drawings. FIG. 1 is a side view schematically showing a sandwich panel manufacturing facility. Such a sandwich panel is used, for example, as a wall material for construction.

図１において、帯状の鋼板製の下面材１は下側に設置された鋼板ロール３から順次繰り出されていき、帯状の鋼板製の上面材２は、上側に設置された鋼板ロール４から順次繰り出されて搬送される。   In FIG. 1, a strip-shaped steel plate lower surface material 1 is sequentially fed out from a steel plate roll 3 installed on the lower side, and a strip-shaped steel plate upper surface material 2 is sequentially fed out from a steel plate roll 4 installed on the upper side. Is transported.

鋼板ロール３から引き出された下面材１は、下面材搬送機構７により搬送されると共に、鋼板ロール４から引き出された上面材２は、上面材搬送機構８により搬送される。また、下面材１が繰り出された先には、下面材１の内表面を機械的に荒すための荒し手段５が設けられている。下面材搬送機構７や上面材搬送機構８は、ロール、ベルトコンベアなどの適宜の搬送機構を用いることができる。   The lower surface material 1 drawn from the steel plate roll 3 is conveyed by the lower surface material conveyance mechanism 7, and the upper surface material 2 drawn from the steel plate roll 4 is conveyed by the upper surface material conveyance mechanism 8. Further, a roughing means 5 for mechanically roughing the inner surface of the lower surface material 1 is provided at a point where the lower surface material 1 is fed. As the lower surface material conveyance mechanism 7 and the upper surface material conveyance mechanism 8, an appropriate conveyance mechanism such as a roll or a belt conveyor can be used.

荒し手段５の搬送下流側には、予熱室９が設けられており、この予熱室９は、搬送される上下面材１，２を予熱するものであり、この予熱室９の下流側にミキシングヘッド１０（原液供給部に相当）が配置される。ミキシングヘッド１０は、ポリイソシアネート成分と、ポリオール化合物、発泡剤などを含むポリオール組成物とを混合した発泡原液組成物が、ノズルから下面材１の面上に幅方向に均一な原液厚さになるように吐出される。   A preheating chamber 9 is provided on the downstream side of the roughing means 5, and the preheating chamber 9 preheats the upper and lower surface materials 1 and 2 to be transported, and mixing is performed downstream of the preheating chamber 9. A head 10 (corresponding to a stock solution supply unit) is disposed. In the mixing head 10, a foamed stock solution composition obtained by mixing a polyisocyanate component and a polyol composition containing a polyol compound, a foaming agent, etc. has a uniform stock solution thickness in the width direction from the nozzle onto the surface of the lower surface material 1. So that it is discharged.

鋼板ロール３，４から引き出された下面材１と上面材２の距離は、下流側に向かうほど徐々に狭くなるように設定されている。ミキシングヘッド１０は、ちょうど下面材１と上面材２の間に配置されている。ミキシングヘッド１０の更に下流側には、発泡室１１（発泡搬送部に相当）が設けられており、所定の温度に設定されている。この発泡室１１において、上下面材１，２を搬送しながら、ウレタン原液を発泡・硬化させて上下面材間にウレタンフォームを生成し、切断装置１２において帯状のサンドイッチパネルを所定の寸法に裁断することで、製品としてのサンドイッチパネルＰが製造される。   The distance between the lower surface material 1 and the upper surface material 2 drawn from the steel sheet rolls 3 and 4 is set so as to gradually decrease toward the downstream side. The mixing head 10 is arranged between the lower surface material 1 and the upper surface material 2. A foaming chamber 11 (corresponding to a foaming conveyance unit) is provided further downstream of the mixing head 10 and is set to a predetermined temperature. In this foaming chamber 11, while transporting the upper and lower surface materials 1 and 2, the urethane stock solution is foamed and cured to generate urethane foam between the upper and lower surface materials, and the cutting device 12 cuts the band-shaped sandwich panel to a predetermined size. By doing so, the sandwich panel P as a product is manufactured.

次に、荒し手段５の具体的な構成を図２に示す。図２（ａ）は、バフ研磨ディスク５ａを使用した例であり、（ｂ）はブラシ５ｂを使用した例である。この荒し手段５は、下面材１の内表面（ポリウレタンフォームが充填される側）を機械的に荒すための機構である。下面材１及び上面材２は、保管時における耐錆性や耐傷性の目的で、両面に塗装が施されている。従って、前述の発泡原液組成物もこのような塗装面に対して吐出されることになるが、ポリウレタンフォームとの密着性の点で問題があり、発泡処理時にボイドが発生するという問題がある。そこで、上記のごとく、荒し手段５を設けて表面を荒くし、ポリウレタンフォームとの密着性がよくなるようにしている。従って、ボイドの発生やセル割れという問題を改善することができる。   Next, a specific configuration of the roughing means 5 is shown in FIG. FIG. 2A shows an example using a buffing disc 5a, and FIG. 2B shows an example using a brush 5b. The roughening means 5 is a mechanism for mechanically roughening the inner surface (side filled with polyurethane foam) of the lower surface material 1. The lower surface material 1 and the upper surface material 2 are coated on both surfaces for the purpose of rust resistance and scratch resistance during storage. Therefore, although the above-mentioned foaming stock solution composition is also discharged onto such a coated surface, there is a problem in terms of adhesion to the polyurethane foam, and there is a problem that voids are generated during the foaming process. Therefore, as described above, the roughening means 5 is provided to roughen the surface so that the adhesion to the polyurethane foam is improved. Therefore, the problems of void generation and cell cracking can be improved.

なお、荒し手段５は、下面材１の内表面のみを機械的に荒くするようにしているが、上面材２の内表面についても同様に荒くしてもよい。ミキシングヘッド１０は、下面材１の上に発泡原液組成物を吐出するようにしているので、下面材１の側に設けることで効果を発揮することができる。   The roughening means 5 mechanically roughens only the inner surface of the lower surface material 1, but the inner surface of the upper surface material 2 may be roughened in the same manner. Since the mixing head 10 discharges the foamed stock solution composition onto the lower surface material 1, the mixing head 10 can exert an effect by being provided on the lower surface material 1 side.

荒し手段５により内表面を荒くする場合、塗料を完全に除去するというのではなく、表面に傷をつける程度でよい。バフ研磨ディスク５ａを用いる場合、種々の研磨砥石、研磨布などが使用可能であり、鋼板や塗装の種類などに応じて、適切なものを選択することができる。また、ブラシ５ｂを使用する場合、ワイヤーブラシなどを好適に使用することができるが、ブラシの材質、ブラシの配置密度（本数）なども適宜選択することができる。荒し手段５の幅方向の大きさは、製造されるサンドイッチパネルの幅寸法（面材の幅寸法）に応じて適宜設定される。   When the inner surface is roughened by the roughening means 5, it is sufficient not to completely remove the paint but to scratch the surface. When the buffing disk 5a is used, various types of polishing wheels, polishing cloths, and the like can be used, and an appropriate one can be selected according to the type of steel plate or coating. Moreover, when using the brush 5b, although a wire brush etc. can be used suitably, the material of a brush, the arrangement density (number) of a brush, etc. can be selected suitably. The size of the roughing means 5 in the width direction is appropriately set according to the width dimension of the manufactured sandwich panel (width dimension of the face material).
