Description

本発明は、金属および硬質表面材料の大板の表および裏面を、疵検査等のために反転させることを容易にする反転機及び検査システムに関する。  The present invention relates to a reversing machine and an inspection system that facilitate reversing the front and back surfaces of a large plate of metal and hard surface material for flaw inspection and the like.

多種多様な加工部品からなる航空機では、安全を確保する上でも、使用される部品の品質確認が重要である。航空機機体にはアルミ材料、炭素繊維、プラスチックなど様々な材料が使用され、種々加工され組み立てられる。機体部位には強度特性が必要であり、アルミニウム材料としては、ジュラルミン、超々ジュラルミンと言われる2000系、7000系、更にはクラッド材も使用されている。  In an aircraft composed of a wide variety of processed parts, it is important to check the quality of the parts used in order to ensure safety. Various materials such as aluminum materials, carbon fibers, and plastics are used for aircraft bodies, and they are variously processed and assembled. The body part must have strength characteristics, and aluminum materials such as duralumin and ultra-duralumin 2000 series, 7000 series, and clad materials are also used.

航空機の胴部、翼部などに使用される大型アルミ部品は、主として熱延されたアルミ合金の厚板(20mm以上)に機械加工が施され、薄肉軽量の骨組構造部材となり、組み立てられる。一方、同じアルミ材料でも5mm以下(薄板)の場合は、主としてプレス加工により穴加工(軽量化)が施され、構造部材の一部品として使用されることが多い。前者の厚板材料(20mm以上)では機械加工(マシニングセンターなど)にて、外面部は切削加工され、表面性状(表面疵、腐食)の影響は少ない。  Large aluminum parts used for aircraft trunks, wings, etc., are mainly machined on a hot-rolled aluminum alloy thick plate (20 mm or more) to form a thin and light frame structure member. On the other hand, even when the same aluminum material is 5 mm or less (thin plate), hole processing (weight reduction) is performed mainly by press working, and it is often used as one part of a structural member. In the former thick plate material (20 mm or more), the outer surface portion is cut by machining (such as a machining center), and the influence of surface properties (surface wrinkles, corrosion) is small.

一方、プレス加工による部品は、板表面がそのまま使用されるので、表面疵および腐食は製品としての性能劣化を招く。そのため、薄板の表面検査は非常に重要であるが、大板であるため取扱いが難しく、また無理をすれば逆に表面疵を付ける恐れがある。特に航空機用には、認定された材料が使用され、海外からの材料も多い。従って、輸送時の疵および腐食に対する検査は、特に注意が必要である。  On the other hand, since the plate surface is used as it is for parts by pressing, surface flaws and corrosion cause performance deterioration as a product. Therefore, surface inspection of a thin plate is very important, but it is difficult to handle because it is a large plate, and if it is impossible, there is a risk of surface flaws. Especially for aircraft, certified materials are used, and there are many materials from overseas. Therefore, special attention must be paid to inspection for flaws and corrosion during transportation.

しかし、このような薄板材料において、確立された検査方法はない。特に数量も少ないため、自動化が検討されることも少ない。そのため、人が反転させて検査するのが一般的と思われ、数十Kgの大板を2人掛かりで反転させるなどを行っている。勿論、上手く支点を用いて反転するものの、反転(積重ね)時に表面疵を付ける恐れがある他、重量物に対する安全確保も難しい。  However, there is no established inspection method for such thin plate materials. Since the quantity is particularly small, automation is rarely considered. For this reason, it is generally considered that a person inverts and inspects, and a large plate of several tens of kilograms is inverted by two persons. Of course, although it reverses using a fulcrum well, there is a risk of surface flaws at the time of reversal (stacking), and it is difficult to ensure safety against heavy objects.

反転機或いは転倒機については、大量生産ライン内、使用頻度の多いもの、重量物(5トン以上のコイル、自動車の金型など)に対しては実用例が確認される。  Regarding reversing machines or overturning machines, practical examples are confirmed for mass-produced lines, those frequently used, and heavy objects (5 tons or more of coils, automobile molds, etc.).

例えば、大量生産では文献1のように建築材料の製造ライン中に反転機が認められる。  For example, in mass production, a reversing machine is recognized in the building material production line as in Document 1.

使用頻度の高いものの例では文献2のようなドラム缶用転倒機、重量物対象ではコイル、金型、コンクリートの転倒機(文献3,4)などがある。しかし、生産量が少なく、重量も数百Kg未満の大板形状のものに対しては、投資効果の観点から転倒機或いは反転機が使用される例を見出すことはできない。  Examples of frequently used ones include a drum can inversion machine as described in Reference 2, and for heavy objects, there are a coil, a mold, a concrete inversion machine (References 3 and 4), and the like. However, it is not possible to find an example in which an overturning machine or an inversion machine is used from the viewpoint of investment effect for a large plate having a small production amount and a weight of less than several hundred kg.

その中で、本発明に近い用途の反転機に、文献5のような合板の貼り合わせのための反転機が確認された。但し、この方法はコンベアを用いた方式であり、本件が嫌う表面疵を招く他、表裏面の検査ができないシステムである。  Among them, a reversing machine for laminating plywood as in Reference 5 was confirmed as a reversing machine for applications close to the present invention. However, this method is a system using a conveyor, which causes a surface flaw that is disliked by the present case, and is a system that cannot inspect the front and back surfaces.

専用の反転機がない場合には、一般的手法としてクレーン、チェーンブロックなどが使用される。軽量(100Kg未満)であれば複数の人手と治具で対応可能であり、特に同じサイズ、重量であれば、比較的安定して反転することもできる。但し、サイズ、重量が変化すると、表面検査および反転を伴う塗油作業において品質保証面、安全作業面で課題が多くなる。  When there is no dedicated reversing machine, a crane, a chain block, etc. are used as a general method. If it is lightweight (less than 100 kg), it can be handled by a plurality of hands and jigs. In particular, if it is the same size and weight, it can be reversed relatively stably. However, when the size and weight are changed, there are many problems in terms of quality assurance and safety work in the oiling work with surface inspection and reversal.

航空機用薄板の板厚は0.2〜5mmと範囲が広く、重量変化もさることながら、板厚による剛性(たわみ)が異なり、ハンドリング性に大きな影響を与える。このような材料について、表裏面の検査、反転時の疵防止、安全な作業にしていくためには、簡易な反転機および容易な作業にしていくことが重要である。本発明では、従来の複数作業者による反転作業を、1人作業で安全・安心で品質保証を行うことができる方法を得ることを目的とする。  The thickness of the aircraft thin plate is as wide as 0.2 to 5 mm, and the rigidity (deflection) varies depending on the plate thickness as well as the weight change, which greatly affects the handling properties. For such materials, in order to inspect the front and back surfaces, prevent wrinkles during reversal, and perform safe work, it is important to use a simple reversing machine and easy work. It is an object of the present invention to obtain a method capable of performing quality assurance with a safe and secure one-person work by reversing work by a plurality of conventional workers.

本発明者らは、上記課題を解決するため、板幅、板長さ1m以上の大きさで、重量5乃至200kgの大板材料の離脱着を反転機に取り付けてある機械的締め付け治具で行ない、また板の反転を手回し機構の回転装置で容易にでき、モーター不要を特徴とする、金属および硬質表面大板材料の反転機をみいだした。  In order to solve the above-mentioned problems, the present inventors have used a mechanical clamping jig having a plate width and a plate length of 1 m or more and a large plate material with a weight of 5 to 200 kg attached to a reversing machine. We have found a reversing machine for metal and hard surface large plate materials, which can be easily performed with a rotating device with a hand-rotating mechanism and does not require a motor.

また、反転機を用いた検査方法であって前記金属および硬質表面大板材料を、表面検査、塗油などの作業の後、バキュームリフトで反転機に供給し、締め付け治具で固定した後、固定された大板が反転された後、治具から脱着すると共に、昇降台で反転機から離脱し、裏面の表面検査、塗油などの作業に供することを特徴とする検査システムを見出した。  Further, in the inspection method using a reversing machine, the metal and the hard surface large plate material, after work such as surface inspection, oiling, supply to the reversing machine with a vacuum lift, after fixing with a tightening jig, After the fixed large plate was reversed, the inspection system was found to be detached from the jig and detached from the reversing machine with the lifting platform, and used for operations such as surface inspection and oiling on the back surface.

表面検査と裏面検査を工程別に行うために、反転機の入側と出側に待機スペースを持ち、移動をバキュームリフト等の昇降台で行うことを特徴とする請求項2の金属および硬質表面大板材料の検査システムを見出した。  3. The metal and hard surface of claim 2, wherein a waiting space is provided on the entry side and the exit side of the reversing machine in order to perform the surface inspection and the back surface inspection, and the movement is performed by a lifting platform such as a vacuum lift. A board material inspection system was found.

本発明は、従来2人作業で行っていた反転作業(表面検査、塗油作業など)を、簡易的な反転機を実用化することにより、1人作業を可能(省人化)とすると共に、反転作業に伴う表面疵の発生を防止し、品質と生産性に優れた反転作業を可能とした。なお、本反転機は種々の用途への横展開も可能である。  The present invention enables reversing work (surface inspection, oiling work, etc.) conventionally performed by two persons to be carried out by one simpler reversing machine (saving labor). Prevents surface flaws caused by reversing work and enables reversing work with excellent quality and productivity. In addition, this reversing machine can be laterally developed for various uses.

The reversing part is made of a welded structure of an aluminum extrusion mold. に本発明の反転機について、側面図を示す。The side view is shown about the reversing machine of this invention. に本発明の反転機について、クランプ部の写真を示す。The photograph of a clamp part is shown about the reversing machine of this invention. に本発明の反転機について、大板を回転させるハンドル部分を示す。Fig. 5 shows a handle portion for rotating a large plate in the reversing machine of the present invention.

片面検査され塗油処理された長さ3.5m、板幅1m、厚み5mmのアルミニウム板(航空機部材7000系材など)をバキュームリフトで図1に示した反転機の台上に載せ、図5に示したクランプで固定する。図示したようにクランプにはアルミと直接に金属部分が接しないようにゴム製のカバーが巻かれている。8か所で固定されていることを確認した後、図6で示したハンドルを操作することでアルミニウム板と図2、図3、図4に示した反転機台が180度回転する。その後は、同じくゴム等を介した昇降機でアルミニウム板を支えるように接触させる。接触後はクランプからアルミニウム板を離脱させ、アルミニウム板を載せた状態で昇降機を下降させ、反転機から次工程の裏面検査及び塗油操作へ移動させる。  A single-side inspected and oiled aluminum plate (length: 3.5 m, plate width: 1 m, thickness: 5 mm) such as an aircraft member 7000 series material is placed on the table of the reversing machine shown in FIG. Secure with the clamp shown in. As shown in the figure, a rubber cover is wound around the clamp so that the metal part does not contact the aluminum directly. After confirming that it is fixed at eight places, the aluminum plate and the reversing machine base shown in FIGS. 2, 3 and 4 are rotated 180 degrees by operating the handle shown in FIG. Thereafter, the aluminum plate is brought into contact with the elevator using rubber or the like. After the contact, the aluminum plate is removed from the clamp, the elevator is lowered with the aluminum plate placed, and the reversing machine is moved to the backside inspection and oiling operation of the next process.

反転機本体は、アルミの押出し型材(溶接接合)により軽量化させられており、回転部両面には機械的締め付け治具が取り付けられている。0.5〜5mm厚の大板を撓みなく固定するため、締め付け治具の間隔は1m以内としている。離脱着時の疵防止を含め、反転機本体および締め付け治具の板接触部には軟質および弾力のある材料で覆うことにより、疵発生を回避する。なお、反転機はハンドルを手回しで回転する方法であり、離脱がスムースに行えるよう、ハンドル部に止め位置が表示されている。  The main body of the reversing machine is reduced in weight by an aluminum extrusion mold material (welding joint), and mechanical clamping jigs are attached to both surfaces of the rotating part. In order to fix a large plate having a thickness of 0.5 to 5 mm without bending, the interval between the fastening jigs is set to 1 m or less. Covering the plate contact parts of the reversing machine main body and the tightening jig with soft and elastic material, including wrinkle prevention at the time of detachment and wearing, avoids wrinkles. The reversing machine is a method of rotating the handle by hand, and a stop position is displayed on the handle portion so that the release can be performed smoothly.

即ち、本発明は板幅、板長さ1m以上の大きさで、重量5〜200Kgまでの大板材料に適用する。1m未満の大きさで5Kg以内であれば、2人での反転作業で何とか品質を確保することは可能であり、敢えて機械設備を使う必要はない。しかし、大きさ1m以上で重量5Kgを超える場合には、2人での反転作業はできても、板の表面品質を確保することは難しい。また重量5Kg未満でも、大きさ1m以上となると、板の撓みにより表面品質(疵防止)を確保することは難しい。重量200Kgを超えると、機械的締め付け治具では反転時にズレ或いは離脱が生じ、同じく表面品質の確保が難しい。従って、本発明は板幅、板長さ1m以上の大きさで、重量5〜200Kgまでの大板材料において、1枚毎の表裏検査、塗油などの作業を可能にすると共に、積重ね作業も容易にできることを特徴とする、金属および硬質表面大板材料の反転機である。なお、200Kgを超える重量においても、機械的締め付け治具の接触面積の増加、並びに取り付け治具の間隔狭小化により、最大1000Kgの重量まで対応は可能である。  That is, the present invention is applied to a large plate material having a width of 1 m or more and a weight of 5 to 200 kg. If the size is less than 1 m and within 5 kg, it is possible to somehow ensure the quality by reversing work by two people, and it is not necessary to use mechanical equipment. However, when the size is 1 m or more and the weight exceeds 5 kg, it is difficult to ensure the surface quality of the plate even if two people can perform the reversing work. Further, even if the weight is less than 5 kg, it is difficult to ensure the surface quality (wrinkle prevention) due to the bending of the plate when the size is 1 m or more. When the weight exceeds 200 kg, the mechanical clamping jig is displaced or detached at the time of reversal, and it is also difficult to ensure the surface quality. Accordingly, the present invention enables the work of front and back inspection, oiling, etc. for each sheet in a large plate material having a width of 1 m or more and a weight of 5 to 200 kg, and also stacking work. It is a reversing machine for metal and hard surface plank materials characterized in that it can be easily done. Even when the weight exceeds 200 kg, a maximum weight of 1000 kg can be accommodated by increasing the contact area of the mechanical clamping jig and reducing the interval between the mounting jigs.

更に板材の離脱着は作業性に大きく影響し、外周全面の固定では作業性を著しく低下させる。従って、本発明では反転機に配置された機械的締め付け治具で行なう。また板の反転を自動で行うことは望ましいが、設備費用がかさむので、反転機片側に手回し機構の回転装置を設置し、モーター不要の省エネタイプの反転機としている。  Furthermore, the separation and attachment of the plate material greatly affects the workability, and the workability is significantly reduced when the entire outer periphery is fixed. Therefore, in this invention, it carries out with the mechanical fastening jig | tool arrange | positioned at the reversing machine. Although it is desirable to automatically reverse the plate, the equipment cost is high, so a rotating device with a hand-rotating mechanism is installed on one side of the reversing machine, making it an energy saving reversing machine that does not require a motor.

本目的の作業は片面ずつ表面検査、塗油などの作業を行うので、途中に反転作業が入る。本発明は、その一連の作業において、反転機を入側と出側の中間位置に置き、大板を固定して反転し、出側の移動式昇降装置に運ばれるものである。  The work for this purpose involves surface inspection, oiling, etc. one side at a time, so reversal work is in the middle. In the present invention, in the series of operations, the reversing machine is placed at an intermediate position between the entry side and the exit side, the large plate is fixed and reversed, and is carried to the exit-side mobile lifting device.

大板は移動式昇降装置で出側の定位置に移動し、改めて裏面の表面検査および塗油などの作業がなされる。本発明は、航空機用薄板に関するものであるが、それ以外への適用も可能であり、金属および硬質表面大板材料の反転機およびその作業方法である。  The large plate is moved to a fixed position on the exit side by a movable lifting device, and operations such as surface inspection and oiling on the back surface are performed again. The present invention relates to an aircraft thin plate, but can be applied to other applications, and is a metal and hard surface large plate material reversing machine and its working method.

本発明の反転機は、薄肉の大板であれば組成材質を問わない。特に航空機用ジュラルミンのような表面品質が最終製品の品質や安全性に影響を与えるような製品の検査、大型のガラスで建材等の表裏両面の疵を嫌うものの検査、さらに大型ディスプレイに利用されるような透明素材の両面検査等様々な材料の両面検査に利用できる。  The reversing machine of the present invention may be made of any material as long as it is a thin large plate. In particular, it is used for inspection of products where surface quality such as duralumin for aircraft affects the quality and safety of the final product, inspection of large glass that dislikes flaws on both sides, such as building materials, and large displays It can be used for double-sided inspection of various materials such as double-sided inspection of transparent materials.
