Description

本発明は、一定の吸入力でも異物の除去効率を増加させることができる異物除去装置に関する。 The present invention relates to a foreign matter removing device capable of increasing the efficiency of removing foreign matter even with a constant suction force.

例えば、熱延鋼板の表面から脱落するスケール等の異物を除去するか、飛散を防止するために、異物が集中的に発生する箇所にカバーを被せ、フードを設置する。フードとしては、包囲式フードを設置して集塵機の容量を増大させて異物を吸入する構造が一般的である。 For example, in order to remove foreign matter such as scale falling from the surface of the hot-rolled steel sheet, or to prevent scattering, a portion where foreign matter is concentrated is covered with a cover and a hood is installed. As for the hood, it is common to install an enclosing hood to increase the capacity of the dust collector and suck in foreign matter.

また、例えば、ローラの間に空気噴射ノズルを設置し、強い空気を鋼板に噴射して飛散するスケール等の異物をカバーで取り囲んで下部フード側に誘導することにより、脱落した異物を捕集して除去する方式も取っている。このようなフードは、鋼板が移動するため鋼板から一定の距離を置いて設置されており、近くに配置することができない。このため異物の除去効率が極めて低い。 In addition, for example, an air injection nozzle is installed between the rollers, and by injecting strong air onto the steel plate and scattering foreign matter such as scale, the cover surrounds the foreign matter such as scale and guides it to the lower hood side, thereby collecting the dropped foreign matter. It also has a method of removing Such hoods are placed at a certain distance from the steel plate due to the movement of the steel plate and cannot be placed close to it. For this reason, the foreign matter removal efficiency is extremely low.

さらに、特定の箇所では、鋼板の下部表面から落ちる異物を除去するためのフードを設置することに構造的な無理がある。このような箇所には単にキャノピー（ｃａｎｏｐｙ）形態のフード吸入口を設置したが、異物の飛散と累積、吸入力の不足などにより除去効率が低下する。 Furthermore, it is structurally unreasonable to install a hood for removing foreign matter falling from the lower surface of the steel plate at a specific location. Although a canopy-shaped hood suction port is installed at such a place, the removal efficiency is lowered due to scattering and accumulation of foreign matter and insufficient suction force.

図１は、本発明の一実施例による異物除去装置を示す斜視図であり、図２は、図１の裏面斜視図である。本発明の一実施例による異物除去装置は、異物を受けるコンベアベルト１０と、このコンベアベルトの一側に配置されて吸入口２１を介して異物を吸入する吸入部２０と、コンベアベルトを選択的に移動させる移動部３０と、を含んでいる。 FIG. 1 is a perspective view showing a foreign matter removing apparatus according to an embodiment of the present invention, and FIG. 2 is a rear perspective view of FIG. A foreign matter removing apparatus according to an embodiment of the present invention includes a conveyor belt 10 for receiving foreign matter, a suction unit 20 disposed on one side of the conveyor belt to suck foreign matter through a suction port 21, and a conveyor belt. and a moving part 30 that moves to the

例えば、本発明の一実施例による異物除去装置は、熱延または冷延鋼板をアンコイリング（ｕｎｃｏｉｌｉｎｇ）するときにアンコイリングが開始されるペイオフリール（ｐａｙ ｏｆｆ ｒｅｅｌ）の下に配置されることができる。 For example, the foreign matter removing apparatus according to an embodiment of the present invention may be placed below a pay off reel where uncoiling is initiated when hot or cold rolled steel is uncoiled. can.

これにより、本発明の一実施例による異物除去装置は、炭素鋼などの鋼板に生じる酸化スケール、特殊鋼に使用され、未反応のパウダー、またはその他の汚染物などのように鋼板の下部表面から脱落して設備の底に積もる異物を除去及び処理することが可能となる。しかし、本発明の一実施例による異物除去装置の適用例は必ずしもこれに限定されない。 Accordingly, the apparatus for removing foreign matter according to an embodiment of the present invention removes oxide scales generated on steel plates such as carbon steel, unreacted powder used for special steels, or other contaminants from the lower surface of the steel plate. It is possible to remove and treat foreign matter that falls off and accumulates on the bottom of the equipment. However, application examples of the foreign matter removing apparatus according to the embodiment of the present invention are not necessarily limited to this.

コンベアベルト１０は支持フレーム１１と、この支持フレームの両側に配置された一対のローラ１２と、これらのローラを巻回するベルト部材１３とを含むことができる。一対のローラ１２のうち少なくとも一つには、その一端にモータ（図示せず）が連結または内蔵されて、ベルト部材１３に駆動力を提供することができる。図面には、管状のローラ本体内にモータとギアが内蔵されたモータローラがローラとして採用されてベルト部材を駆動する例が示されている。 Conveyor belt 10 may include a support frame 11, a pair of rollers 12 positioned on opposite sides of the support frame, and a belt member 13 encircling the rollers. At least one of the pair of rollers 12 may have a motor (not shown) connected to or incorporated in one end thereof to provide driving force to the belt member 13 . The drawing shows an example in which a motor roller, in which a motor and gears are built in a tubular roller body, is employed as the roller to drive the belt member.

ベルト部材１３は、例えば、ゴムやウレタン樹脂、シリコンなどのような弾性材質で作製されることができる。このベルト部材は、支持フレーム１１よりもやや小さいサイズを有する。このようなコンベアベルト１０は、自由落下して落ちるスケール等の異物を受けて集める役割を果たす。ベルト部材１３は、撓むことなくその上部表面が均一に平坦な表面を形成することが好ましい。 The belt member 13 can be made of, for example, an elastic material such as rubber, urethane resin, or silicon. This belt member has a size slightly smaller than that of the support frame 11 . The conveyor belt 10 serves to receive and collect foreign substances such as scales that fall freely. The belt member 13 preferably forms a uniformly flat upper surface without bending.

吸入部２０は、略ダクト状の部材であって、コンベアベルト１０の一側に配置されるが、その吸入口２１は、コンベアベルトのサイズと同一またはより大きいサイズを有することがよい。より具体的に、コンベアベルトのベルト部材１３の移動方向に直角である方向を幅方向とするとき、吸入口は少なくともベルト部材の幅方向長さに対応する幅方向長さを有する。 The suction part 20 is a substantially duct-like member and is arranged on one side of the conveyor belt 10, and its suction port 21 may have a size equal to or larger than the size of the conveyor belt. More specifically, when the direction perpendicular to the moving direction of the belt member 13 of the conveyor belt is defined as the width direction, the inlet has a width direction length corresponding to at least the width direction length of the belt member.

吸入部２０は、上方に向かうほど、その幅方向長さまたは厚み方向長さが減少するように形成されてもよい。また、吸入部２０は、所定の角度で傾斜して位置することが好ましい。しかし、必ずしもこれに限定されず、空間的な余裕があれば吸入部が水平に位置してもよい。 The suction part 20 may be formed such that its width direction length or thickness direction length decreases as it goes upward. In addition, it is preferable that the suction unit 20 is positioned to be inclined at a predetermined angle. However, it is not necessarily limited to this, and the suction part may be positioned horizontally if there is a spatial margin.

さらに、本発明の一実施例による異物除去装置は、図１に示すように、吸入部２０の上部を覆い被さって、吸入部とともに又は別個に傾斜して位置し、自由落下して落ちる異物が傾斜した表面に沿ってコンベアベルト１０に向かって円滑に摺動できるようにする傾斜板４０を含むことができる。 In addition, as shown in FIG. 1, the foreign object removing apparatus according to the embodiment of the present invention covers the upper part of the suction unit 20 and is positioned at an angle together with or separately from the suction unit so that the free falling foreign objects can be removed. An inclined plate 40 may be included to allow smooth sliding along an inclined surface toward the conveyor belt 10 .

傾斜板４０の傾斜角は、水平面に対して約３０度～９０度の間であることが好ましいが、これに限定されず、傾斜板の表面粗さまたは異物の粘度等に応じて傾斜角が決定されてもよい。また、傾斜板４０の傾斜角が水平面に対して約３０度未満である場合には、この傾斜板に振動を付与する振動部材５０（図４参照）が備えられることがよい。このような振動部材としては、電気駆動方式、電子駆動方式、エア駆動方式のバイブレータ（ｖｉｂｒａｔｏｒ）等が採用されてもよい。このような振動部材は傾斜板の裏面に配置されてもよい。 The inclination angle of the inclined plate 40 is preferably between about 30 degrees and 90 degrees with respect to the horizontal plane, but is not limited to this. may be determined. Further, when the inclination angle of the inclined plate 40 is less than about 30 degrees with respect to the horizontal plane, it is preferable to provide a vibrating member 50 (see FIG. 4) that imparts vibration to the inclined plate. As such a vibrating member, an electric drive type, an electronic drive type, an air drive type vibrator, or the like may be employed. Such a vibrating member may be arranged on the underside of the inclined plate.

吸入口２１の反対側において吸入部２０は、図示しない吸入管に連結されることができ、この吸入管は、例えば、吸引ファンまたは真空ポンプ、集塵機などのような吸入手段に連結されることができる。 On the opposite side of the suction port 21, the suction part 20 can be connected to a suction pipe (not shown), and this suction pipe can be connected to a suction means such as a suction fan, a vacuum pump, a dust collector, or the like. can.

このように構成された本発明の一実施例による異物除去装置では、コンベアベルト１０がそのベルト部材１３上に積もる異物を持続的に移送することができる。異物はベルト部材の移動を介して吸入部２０の吸入口２１まで移送されて吸入される。 In the apparatus for removing foreign substances according to the embodiment of the present invention, the conveyor belt 10 can continuously transfer the foreign substances accumulated on the belt member 13 . Foreign matter is transferred to the suction port 21 of the suction unit 20 through the movement of the belt member and is sucked.

図２にさらに詳細に示されるように、移動部３０は、ベース部３１に設置され、コンベアベルト１０の支持フレーム１１に連結されてコンベアベルト全体を線形移動させることができる。 As shown in more detail in FIG. 2, the moving section 30 is mounted on a base section 31 and coupled to the support frame 11 of the conveyor belt 10 to allow linear movement of the entire conveyor belt.

ベース部３１は、例えば、略フレーム状に形成された部材であって、移動部３０を支持してその移動を案内する役割を果たす。ベース部はフレーム状に形成されることに必ずしも限定されない。 The base portion 31 is, for example, a substantially frame-shaped member that supports the moving portion 30 and guides its movement. The base portion is not necessarily limited to being formed in a frame shape.

移動部３０は、ベース部３１の上部に設置され、移動部の作動ロッド３２（図４参照）が支持フレーム１１の下部に連結されることができる。このような移動部３０としては、作動ロッド３２を備えた流体圧シリンダや電気式アクチュエータなどを採択することができる。 The moving part 30 may be installed on the upper part of the base part 31 and the operating rod 32 (see FIG. 4) of the moving part may be connected to the lower part of the support frame 11 . A fluid pressure cylinder having an operating rod 32, an electric actuator, or the like can be adopted as the moving part 30 as described above.

ベース部３１とコンベアベルト１０との間の相対移動を案内し、円滑な移動を保障するために、ベース部とコンベアベルトの支持フレーム１１との間にレール部材３３が介在されてもよい。例えば、支持フレームに滑走部が設置され、ベース部にレール部材が設置されて滑走部がレール部材に沿って摺動することにより、支持フレーム及びコンベアベルトが移動部３０の駆動によって円滑に線形移動することができる。 A rail member 33 may be interposed between the base portion and the support frame 11 of the conveyor belt to guide the relative movement between the base portion 31 and the conveyor belt 10 and to ensure smooth movement. For example, a sliding part is installed on the support frame, a rail member is installed on the base part, and the sliding part slides along the rail member, so that the support frame and the conveyor belt are smoothly linearly moved by driving the moving part 30. can do.

図３は、図１に示す異物除去装置のうち、コンベアベルトの移動状態を示す斜視図である。ここに示すように、ベース部３１は、異物を受けるコンベアベルト１０を支持することができる。例えば、本発明の一実施例による異物除去装置がアンコイリングに適用されるとき、新たに装着されるコイルとの干渉をなくすように移動部３０の作動下でコンベアベルトが吸入部２０の下とベース部３１の上部表面との間の空間に摺動することができる。 3 is a perspective view showing a moving state of a conveyor belt in the foreign matter removing apparatus shown in FIG. 1. FIG. As shown here, the base portion 31 can support the conveyor belt 10 for receiving foreign objects. For example, when the apparatus for removing foreign matter according to an embodiment of the present invention is applied to uncoiling, the conveyer belt moves under the suction unit 20 under the operation of the moving unit 30 so as to eliminate interference with a newly installed coil. It can slide into the space between the upper surface of the base portion 31 .

図４は、本発明の一実施例による異物除去装置の変形例を示す図である。ここに示すように、本発明の一実施例による異物除去装置において、コンベアベルト１０のベルト部材１３は、その外周面上に略直立して形成され、互いに所定の間隔で離隔して配置され、ベルト部材の全幅にわたって延長した複数のブレード１４をさらに含むことができる。 FIG. 4 is a diagram showing a modification of the foreign matter removing device according to one embodiment of the present invention. As shown here, in the foreign matter removing apparatus according to one embodiment of the present invention, the belt members 13 of the conveyor belt 10 are formed substantially upright on the outer peripheral surface thereof, and are spaced apart from each other by a predetermined distance, It may further include a plurality of blades 14 extending across the width of the belt member.

これらのブレード１４は、ベルト部材１３と一体的に形成されてもよく、少なくともベルト部材と類似の弾性材質で形成された後に接合されてもよい。このような各々のブレード１４は、ローラ１２の駆動によりベルト部材１３が吸入部２０の吸入口２１に向かって移動する際に、吸入部の吸入口に接触または嵌合されて吸入口の開放面を閉鎖するようになる。これにより、吸入部内に一時的に真空を形成するようになり、このような真空によって、例えば、既存の集塵機の一定の吸入力でも、吸入部は十分に異物を吸入して捕集し、吸入管を経て異物を除去することができるようになる。 These blades 14 may be formed integrally with the belt member 13, or may be joined after being formed of at least an elastic material similar to that of the belt member. When the belt member 13 moves toward the suction port 21 of the suction unit 20 by driving the rollers 12, each blade 14 is in contact with or fitted to the suction port opening surface of the suction port. will be closed. As a result, a vacuum is temporarily formed in the suction part, and due to such a vacuum, the suction part sufficiently sucks and collects the foreign matter even with a constant suction force of the existing dust collector. Foreign matter can be removed through the tube.

各ブレード１４は、吸入部２０の吸入口２１と接触した後、ベルト部材１３の駆動によって前進しながら弾性変形、すなわち反ることにより、吸入部の下を通ることができる。これにより、ベルト部材は大きな無理なく持続的に循環移動することができる。 After coming into contact with the suction port 21 of the suction section 20, each blade 14 is driven by the belt member 13 to move forward while elastically deforming, that is, warping, so that it can pass under the suction section. As a result, the belt member can be continuously circulated without much difficulty.

以下では、本発明の一実施例による異物除去装置の作動について簡略に説明する。便宜上、本発明の一実施例による異物除去装置が、熱延または冷延鋼板１（図４参照）のアンコイリングが開始されるペイオフリール２（図４参照）の下に配置された場合を例に挙げて説明する。 Hereinafter, the operation of the foreign matter removing apparatus according to an embodiment of the present invention will be briefly described. For convenience, it is assumed that the foreign matter removing apparatus according to one embodiment of the present invention is arranged below the payoff reel 2 (see FIG. 4) where the uncoiling of the hot-rolled or cold-rolled steel sheet 1 (see FIG. 4) is started. will be described.

上述のように鋼板が移動しているため、フードを鋼板に接触または近接配置させることができない。これにより、鋼板の下部表面においてスケール、パウダー、汚染物等の異物が落ちて設備周辺の環境を汚染させているにも関わらず、従来のフードは単に集塵機の吸入力にのみ依存することで、異物の除去効率が低くなっていた。 Since the steel plate is moving as described above, the hood cannot be placed in contact with or close to the steel plate. As a result, foreign matter such as scale, powder, and contaminants fall on the lower surface of the steel plate and contaminate the environment around the facility. The foreign matter removal efficiency was low.

本発明の一実施例による異物除去装置では、鋼板１のアンコイリングのための準備が完了すると、移動部３０が作動してベース部３１に重なっているコンベアベルト１０を前進位置に移動させる。アンコイリングの開始とともに、鋼板１の下部表面から脱落して自由落下する異物は、コンベアベルト１０のベルト部材１３に徐々に蓄積する。一部の異物は傾斜板４０を経由してベルト部材上に載置される。 In the apparatus for removing foreign substances according to an embodiment of the present invention, when the preparation for uncoiling the steel plate 1 is completed, the moving part 30 operates to move the conveyor belt 10 overlapping the base part 31 to the forward position. With the start of uncoiling, the foreign substances falling off the lower surface of the steel plate 1 and free-falling gradually accumulate on the belt member 13 of the conveyor belt 10 . Part of the foreign matter is placed on the belt member via the inclined plate 40 .

コンベアベルト１０の一対のローラ１２のうち少なくとも一つがベルト部材１３を駆動させることにより、ベルト部材は、持続的に吸入部２０の吸入口２１を通ってローラを巻回しながら循環移動することができる。ベルト部材１３が吸入部２０の吸入口２１に向かって移動することによって、ベルト部材の上部表面に積もる異物を吸入口まで移送することができる。 At least one of the pair of rollers 12 of the conveyor belt 10 drives the belt member 13 so that the belt member can continuously circulate through the suction port 21 of the suction unit 20 while winding the rollers. . As the belt member 13 moves toward the suction port 21 of the suction unit 20, the foreign matter accumulated on the upper surface of the belt member can be transferred to the suction port.

このように、異物が吸入部２０の吸入口２１に近接して移送されることによって、吸入部は一定の吸入力でも十分に異物を吸入して捕集し、吸入管を経て異物を除去することができる。 In this way, the foreign substances are transferred to the vicinity of the suction port 21 of the suction unit 20, so that the suction unit sufficiently sucks and collects the foreign substances even with a constant suction force, and removes the foreign substances through the suction pipe. be able to.

一方、コンベアベルト１０のベルト部材１３の外周面上に複数のブレード１４が形成された場合に、各々のブレードは、吸入部２０の吸入口２１に接触または嵌合されて吸入口の開放面を閉鎖するようになり、これにより、吸入部内に一時的に生じる真空によって吸入部は一定の吸入力でも十分に異物を吸入して捕集し、吸入管を経て異物を除去することができる。 On the other hand, when a plurality of blades 14 are formed on the outer peripheral surface of the belt member 13 of the conveyor belt 10, each blade is in contact with or fitted to the suction port 21 of the suction section 20, and faces the opening surface of the suction port. As a result, the vacuum temporarily generated in the suction part allows the suction part to sufficiently suck and collect foreign matter even with a constant suction force, and remove the foreign matter through the suction pipe.

各ブレード１４は、吸入部２０の吸入口２１と接触した後、ベルト部材１３の駆動により弾性変形、すなわち反ることにより、吸入部の下を通るようになる。鋼板１のアンコイリングが完了して新たなコイルを装着しようとするときには、新たなコイルと干渉しないように、移動部３０が作動してコンベアベルト１０の支持フレーム１１がレール部材３３の案内に沿って吸入部２０の下とベース部３１の上部表面との間の空間に摺動して後進位置に到達可能となる。 After coming into contact with the suction port 21 of the suction section 20, each blade 14 is elastically deformed, that is, warped by the driving of the belt member 13, so that it passes under the suction section. When the uncoiling of the steel plate 1 is completed and a new coil is to be installed, the moving part 30 operates to move the support frame 11 of the conveyor belt 10 along the guide of the rail member 33 so as not to interfere with the new coil. can slide into the space between the bottom of the intake section 20 and the upper surface of the base section 31 to reach the reverse position.

以上のように本発明によると、自由落下して積もる様々な大きさのスケールや表面処理用パウダー、汚染物等の異物を吸入部の吸入口まで誘導することにより、既存の集塵機性能において除去効率を高めることができる。 As described above, according to the present invention, by guiding foreign matter such as scales of various sizes, surface treatment powder, and contaminants that are free-falling and accumulated to the suction port of the suction unit, the removal efficiency is improved compared to the performance of the existing dust collector. can increase
