Description

本発明は、積層された鋼板（以下「鋼板積層体」という）から鋼板を１枚ずつ分離する方法および鋼板積層体から鋼板を１枚ずつ分離して取り出す装置に関するものである。   The present invention relates to a method for separating steel sheets one by one from laminated steel sheets (hereinafter referred to as “steel sheet laminates”) and an apparatus for separating and taking out steel sheets one by one from a steel sheet laminate.

鋼板積層体から最上段の鋼板を１枚ずつ取り出す装置としては、２枚取りを防止するために、上部の数枚程度の鋼板をマグネットセパレータで一旦分離させるタイプのものがある（例えば、特許文献１、２参照）。   As an apparatus for taking out the uppermost steel sheets one by one from the steel sheet laminate, there is a type in which several upper steel sheets are once separated by a magnetic separator in order to prevent two sheets (for example, patent documents) 1 and 2).

特開平１１−１３９５９４号公報 実開平７−１３８５０号公報 In FIG. 3, (a) is a side explanatory view of a steel plate separating and taking out apparatus provided with a magnet separator, and (b) is an enlarged view around the magnet separator. A steel plate 1 is stacked and mounted on a mounting table 2 configured to be movable up and down, and a magnet separator 3 is fixedly installed so as to face an edge of the stacked body. The same magnetic pole is induced in each steel plate 1 by the magnet separator 3, the induced magnetic poles repel each other, and the steel plates 1 are separated one by one by the repulsive force (referred to as magnetic repulsive force). Each of the separated steel plates 1 is once pressed to the original stacked state in which the steel plates 1 come into contact with each other by the suction pad 4 that is lowered by the drive of the cylinder 5, but an oil film is formed on the surface of the steel plate 1 as described later. Even if formed, since air enters between the separated steel plates 1, a large adhesion force does not occur again between them, and only the uppermost steel plate 1 </ b> A is adsorbed by the suction pad 4 and is transferred to the next process. Supplied.
Japanese Patent Laid-Open No. 11-139594 Japanese Utility Model Publication No. 7-13850

鋼板１の表面に切削油などの油が付着している場合、その油膜の介在によって鋼板１間の密着力が磁気反発力よりも大きくなると、例えば図３（ｂ）に示す鋼板１Ｂ、１Ｃのように互いが完全に分離せず、吸着パッド４が鋼板１Ｂ、１Ｃを２枚取りするおそれがある。鋼板１の分離を確実にするためには、磁気反発力を高めるべく磁力の強いマグネットセパレータ３を使用すればよいが、既存の設備に対する代替購入、付け替え作業等の問題を考えると不経済である。   When oil such as cutting oil adheres to the surface of the steel plate 1, if the adhesion force between the steel plates 1 becomes larger than the magnetic repulsive force due to the oil film interposed therebetween, for example, the steel plates 1B and 1C shown in FIG. As described above, the suction pads 4 may take two steel plates 1B and 1C without being completely separated from each other. In order to ensure the separation of the steel plate 1, the magnetic separator 3 having a strong magnetic force may be used in order to increase the magnetic repulsive force, but it is uneconomical considering problems such as alternative purchases and replacement work for existing equipment. .

本発明は、以上のような問題を解決するために創作されたものであり、簡易な構成で鋼板をより確実に分離できる鋼板の分離方法および分離取り出し装置を提供することを目的としている。   The present invention has been created to solve the above-described problems, and an object of the present invention is to provide a steel plate separation method and a separation take-out device that can separate steel plates more reliably with a simple configuration.

本発明は、前記課題を解決するため、積層された鋼板の一端側に隣接して設けられたマグネットセパレータを用いて鋼板同士間に磁気反発力を生じさせる鋼板の分離方法であって、前記マグネットセパレータに臨ませた前記積層された鋼板を下降させたときに、それぞれの鋼板が、前記マグネットセパレータに着磁することよって、鋼板間に間隙を生じさせ、「上の鋼板から受ける反発力＞下の鋼板から受ける反発力」の関係から、鋼板を分離させる構成としたことを特徴とする鋼板の分離方法とした。   In order to solve the above-mentioned problem, the present invention is a method for separating steel plates, in which a magnetic repulsion force is generated between steel plates using a magnet separator provided adjacent to one end side of the laminated steel plates. When the laminated steel plates facing the separator are lowered, each steel plate is magnetized on the magnet separator, thereby creating a gap between the steel plates, and “repulsive force received from the upper steel plate> lower From the relationship of “repulsive force received from the steel plate”, the steel plate separation method is characterized in that the steel plate is separated.

この分離方法によれば、鋼板積層体を下降させることにより、鋼板が自重により落下できるだけの変位量を確保できる。鋼板が自重によって落下するとき、マグネットセパレータを臨む鋼板の一端には、マグネットセパレータに着磁しようとする力が働いている。鋼板の姿勢等によってそれぞれの鋼板に働く着磁力は均一とはならず、この力は鋼板間の反発力と同じ方向もしくは、反発力を高める方向に働く。この作用及び前記確保された変位量によって、「上の鋼板から受ける反発力＞下の鋼板から受ける反発力」の関係が生じ、鋼板同士を分離させる。   According to this separation method, by lowering the steel sheet laminate, it is possible to secure a displacement that allows the steel sheet to fall by its own weight. When the steel sheet falls due to its own weight, a force to magnetize the magnetic separator acts on one end of the steel sheet facing the magnet separator. The applied magnetic force acting on each steel sheet does not become uniform depending on the posture of the steel sheet, and this force acts in the same direction as the repulsive force between the steel sheets or in the direction to increase the repulsive force. The relationship of “repulsive force received from the upper steel plate> repulsive force received from the lower steel plate” is generated by this action and the secured displacement amount, and the steel plates are separated from each other.

また本発明は、鋼板積層体を載置する昇降自在な載置台と、鋼板積層体の一端側に隣接して設けられ、鋼板同士間において磁気反発力を生じさせるマグネットセパレータと、鋼板積層体の最上段の鋼板を取り出す取り出し部と、を備えた鋼板の分離取り出し装置であって、前記マグネットセパレータに鋼板積層体を臨ませた状態で前記載置台を下降させ、それぞれの鋼板が、前記マグネットセパレータに着磁することよって、鋼板間に間隙を生じさせ、「上の鋼板から受ける反発力＞下の鋼板から受ける反発力」の関係から、鋼板を分離させる構成としたことを特徴とする鋼板の分離取り出し装置とした。   The present invention also includes a mounting table on which the steel plate laminate can be placed, a magnet separator that is provided adjacent to one end of the steel plate laminate, and generates a magnetic repulsive force between the steel plates, and a steel plate laminate. An apparatus for separating and taking out a steel plate, comprising a take-out portion for taking out the uppermost steel plate, wherein the mounting table is lowered with the steel plate facing the magnet separator, and each steel plate is separated from the magnet separator. The steel sheet is characterized by having a structure in which the steel sheet is separated from the relationship of “repulsive force received from the upper steel sheet> repulsive force received from the lower steel sheet”. A separation and removal device was obtained.

この分離取り出し装置によれば、載置台を下降させ、鋼板積層体を下降させることにより、鋼板が自重により落下できるだけの変位量を確保できる。鋼板が自重によって落下するとき、マグネットセパレータを臨む鋼板の一端には、マグネットセパレータに着磁しようとする力が働いている。鋼板の姿勢等によってそれぞれの鋼板に働く着磁力は均一とはならず、この力は鋼板間の反発力と同じ方向もしくは、反発力を高める方向に働く。この作用及び前記確保された変位量によって、「上の鋼板から受ける反発力＞下の鋼板から受ける反発力」の関係が生じ、鋼板同士を分離させる。
また、この分離取り出し装置は、既存の装置に対して、載置台を下降させる制御を加えるだけで実現可能となるので、汎用性および経済性に優れる。 According to this separation and take-out device, it is possible to secure a displacement that allows the steel sheet to fall by its own weight by lowering the mounting table and lowering the steel sheet laminate. When the steel sheet falls due to its own weight, a force to magnetize the magnetic separator acts on one end of the steel sheet facing the magnet separator. The applied magnetic force acting on each steel sheet does not become uniform depending on the posture of the steel sheet, and this force acts in the same direction as the repulsive force between the steel sheets or in the direction to increase the repulsive force. The relationship of “repulsive force received from the upper steel plate> repulsive force received from the lower steel plate” is generated by this action and the secured displacement amount, and the steel plates are separated from each other.
Moreover, since this separation / extraction apparatus can be realized simply by adding control for lowering the mounting table to an existing apparatus, it is excellent in versatility and economy.

本発明によれば、簡易な構成で鋼板をより確実に分離できる。また、既存の分離取り出し装置にも容易に適用可能となる。   According to the present invention, a steel plate can be more reliably separated with a simple configuration. In addition, the present invention can be easily applied to an existing separation / extraction apparatus.

図１は本発明に係る鋼板の分離取り出し装置の作用説明図、図２は鋼板の下降分離に関する作用説明図である。これらの図において、各構成部材については図３と同一の符号を付している。すなわち、本発明に係る鋼板の分離取り出し装置は、鋼板積層体を載置する昇降自在な載置台２と、鋼板積層体の一端側に隣接して設けられ、鋼板１同士間において磁気反発力Ｒを生じさせるマグネットセパレータ３と、鋼板積層体の最上段の鋼板１を取り出す取り出し部（吸着パッド４）と、を備える。   FIG. 1 is an operation explanatory diagram of a steel sheet separating and taking out apparatus according to the present invention, and FIG. In these drawings, the same reference numerals as those in FIG. That is, the steel plate separating and taking out apparatus according to the present invention is provided adjacent to one end side of the steel plate laminate, which can be raised and lowered to place the steel plate laminate, and the magnetic repulsive force R between the steel plates 1. And a take-out portion (suction pad 4) for taking out the uppermost steel plate 1 of the steel plate laminate.

図１（ａ）は、載置台２を上昇させて鋼板積層体の上部をマグネットセパレータ３に臨ませ、鋼板１Ａ〜１Ｅをマグネットセパレータ３に吸着させた状態を示している。なお、載置台２の上昇停止は、図示しないセンサ（光学センサ等）により最上段の鋼板１Ａの高さ位置を検出することで行う。   FIG. 1A shows a state in which the mounting table 2 is raised so that the upper part of the steel plate laminate faces the magnet separator 3 and the steel plates 1A to 1E are attracted to the magnet separator 3. FIG. The raising and stopping of the mounting table 2 is performed by detecting the height position of the uppermost steel plate 1A by a sensor (such as an optical sensor) (not shown).

本来であれば、図１（ａ）の状態で各鋼板１Ａ〜１Ｅはすべて互いに分離するのであるが、既述したように油膜等による密着力の影響で鋼板１同士が分離しない場合がある。図１（ａ）では、鋼板１Ｂと鋼板１Ｃとが分離せずに密着した場合を示している。本発明は、この図１（ａ）の状態から載置台２を下降させ、「鋼板にかかる重力＞下の鋼板から受ける磁気反発力」の関係から鋼板１をその自重により下降分離させる構成としている。   Originally, the steel plates 1A to 1E are all separated from each other in the state of FIG. 1A, but as described above, the steel plates 1 may not be separated from each other due to the influence of the adhesion force due to the oil film or the like. FIG. 1A shows a case where the steel plate 1B and the steel plate 1C are in close contact with each other without being separated. In the present invention, the mounting table 2 is lowered from the state of FIG. 1A, and the steel plate 1 is lowered and separated by its own weight from the relationship of “gravity applied to the steel plate> magnetic repulsive force received from the lower steel plate”. .

その下降分離の作用について図２を参照して説明する。図２（ａ）は、図１（ａ）のマグネットセパレータ３周りを拡大した図である。
鋼板１Ｃに着目すると、上の鋼板１Ｂから分離する方向に作用する重力Ｇは、下の鋼板１Ｄから受ける磁気反発力と釣り合っている状態である。すなわち、静的な状態では、鋼板１Ｃに関して、「鋼板１Ｃにかかる重力Ｇ＝下の鋼板１Ｄから受ける磁気反発力Ｒ」の関係にある。 The action of the descending separation will be described with reference to FIG. FIG. 2A is an enlarged view around the magnet separator 3 in FIG.
Focusing on the steel plate 1C, the gravity G acting in the direction separating from the upper steel plate 1B is in a state balanced with the magnetic repulsive force received from the lower steel plate 1D. That is, in the static state, the steel plate 1C has a relationship of “gravity G applied to the steel plate 1C = magnetic repulsive force R received from the lower steel plate 1D”.

載置台２（図１）が下降して、鋼板１Ｅがマグネットセパレータ３の磁極部から外れると、磁極化の弱まった鋼板１Ｅにほぼ重なるように、鋼板１Ｄが自重により下降する（図２（ｂ）の状態）。
その瞬間、鋼板１Ｃと鋼板１Ｄとの距離が大きくなるから、鋼板１Ｃに関して鋼板１Ｄから受ける磁気反発力Ｒが弱まることになる。鋼板１Ｄから受ける磁気反発力が弱まると、密着した鋼板１Ｂと鋼板１Ｃが自重により下降する。 When the mounting table 2 (FIG. 1) is lowered and the steel plate 1E is detached from the magnetic pole portion of the magnet separator 3, the steel plate 1D is lowered by its own weight so that it substantially overlaps the steel plate 1E whose magnetic pole is weakened (FIG. 2B). ) State).
At that moment, since the distance between the steel plate 1C and the steel plate 1D is increased, the magnetic repulsive force R received from the steel plate 1D with respect to the steel plate 1C is weakened. When the magnetic repulsive force received from the steel plate 1D is weakened, the closely-attached steel plate 1B and the steel plate 1C are lowered by their own weight.

このように密着した鋼板１Ｂと鋼板１Ｃは、下降しているとき下の鋼板１Ｄからの反発力Ｒの影響をあまり受けなくなり、鋼板１Ｃは下方向への移動が可能となる。そして、鋼板１Ｂと鋼板１Ｃとの間は、密着力と密着力の逆方向に働く磁気反発力が支配的となる。   The steel plate 1B and the steel plate 1C that are in close contact with each other are less affected by the repulsive force R from the lower steel plate 1D when descending, and the steel plate 1C can be moved downward. And between the steel plate 1B and the steel plate 1C, the magnetic repulsive force acting in the opposite direction of the adhesion force and the adhesion force becomes dominant.

鋼板１Ｂと鋼板１Ｃの一端は、マグネットセパレータから吸着方向の力を受けており、鋼板の下降時には、下降を抑制する方向の抵抗力となる。詳細に見れば、鋼板１Ｂの一端とマグネットセパレータとの当接面では、下降する鋼板１Ｂの荷重と着磁による抵抗力ＭＲ１が働き、同様に鋼板１Ｃの一端とマグネットセパレータとの当接面でも、下降する鋼板１Ｃの荷重と着磁による抵抗力ＭＲ２が働いている。抵抗力ＭＲ１、ＭＲ２は、鋼板１Ｂ、１Ｃの姿勢、角度、両者の重なり状態によって同じとはならない。   One end of the steel plate 1B and the steel plate 1C receives a force in the attracting direction from the magnet separator, and when the steel plate is lowered, it has a resistance force in a direction to suppress the descent. If it sees in detail, the resistance force MR1 by the load and magnetization of the steel plate 1B which descend | falls will work at the contact surface of the end of the steel plate 1B and the magnet separator, and also the contact surface of the end of the steel plate 1C and the magnet separator. The load of the descending steel plate 1C and the resistance force MR2 due to magnetization are working. The resistance forces MR1 and MR2 are not the same depending on the postures and angles of the steel plates 1B and 1C and the overlapping state of the two.

抵抗力ＭＲ１が抵抗力ＭＲ２に比べて大きい場合には、抵抗力の差（ＭＲ１−ＭＲ２）は、鋼板１Ｂと鋼板１Ｃとの間の磁気反発力と同方向に働き、相対的に密着力を弱め両者間の間隙（密着層の厚さ）を大きくし、場合によっては、両者を分離させる。
一旦、鋼板１Ｂと鋼板１Ｃとの密着力が弱まれば、前記したように鋼板１Ｃに関して鋼板１Ｄから受ける磁気反発力Ｒも弱まっており、「上の鋼板１Ａから受ける反発力＞下の鋼板から受ける反発力」の関係から、鋼板１Ｂと鋼板１Ｃとの間隙はさらに開き、両者を分離させる。 When the resistance force MR1 is larger than the resistance force MR2, the difference in resistance force (MR1-MR2) works in the same direction as the magnetic repulsion force between the steel plate 1B and the steel plate 1C, and relatively increases the adhesion force. The gap between the two is weakened (the thickness of the adhesion layer), and in some cases, the two are separated.
Once the adhesion between the steel plate 1B and the steel plate 1C is weakened, the magnetic repulsive force R received from the steel plate 1D with respect to the steel plate 1C is also weakened as described above. From the relationship of “repulsive force received”, the gap between the steel plate 1B and the steel plate 1C is further opened to separate them.

一方、抵抗力ＭＲ１が抵抗力ＭＲ２に比べて小さい場合には、抵抗力の差（ＭＲ１−ＭＲ２）は、鋼板１Ｂと鋼板１Ｃとの間の磁気反発力と逆方向に働き、相対的に鋼板間の反発力を高め、その反動によって、両者間の間隙（密着層の厚さ）を大きくし、密着力を弱め、場合によっては、両者を分離させる。
一旦、鋼板１Ｂと鋼板１Ｃとの密着力が弱まれば、前記したように鋼板１Ｃに関して鋼板１Ｄから受ける磁気反発力Ｒも弱まっており、「上の鋼板１Ａから受ける反発力＞下の鋼板から受ける反発力」の関係から、鋼板１Ｂと鋼板１Ｃとの間隙はさらに開き、両者を分離させる（図２（ｃ）参照）。 On the other hand, when the resistance force MR1 is smaller than the resistance force MR2, the difference in resistance force (MR1-MR2) acts in the opposite direction to the magnetic repulsion force between the steel plate 1B and the steel plate 1C, and is relatively steel plate. By increasing the repulsive force between them, the reaction increases the gap (thickness of the adhesive layer) between them, weakens the adhesive force, and in some cases separates them.
Once the adhesion between the steel plate 1B and the steel plate 1C is weakened, the magnetic repulsive force R received from the steel plate 1D with respect to the steel plate 1C is also weakened as described above. From the relationship of “repulsive force received”, the gap between the steel plate 1B and the steel plate 1C is further opened to separate them (see FIG. 2C).

以上により図１（ｂ）のように鋼板１Ａ〜１Ｄが分離した状態となり、次いで図１（ｃ）に示すように吸着パッド４が下降して鋼板１Ａ〜１Ｄを一旦押圧し、図１（ｄ）に示すように鋼板１Ａを吸着して次工程に供給する。鋼板１Ｂ〜１Ｄも既に分離しているので、引き続き、載置台２を停止させたまま、吸着パッド４により鋼板１Ｄまで順次取り出すことが可能である。既述したように、一旦分離した鋼板１同士の間には空気が入り込むので、吸着パッド４により押圧しても鋼板１同士に大きな密着力が再び生ずることはなく、常に最上段の鋼板１だけが吸着パッド４に吸着される。なお、図１（ａ）、（ｂ）の状態で図示しないエアブロアによりエアを各鋼板１の隙間に吹き付ければ、再度の密着力の発生を効果的に低減できる。   As a result, the steel plates 1A to 1D are separated as shown in FIG. 1B, and then the suction pad 4 is lowered to press the steel plates 1A to 1D once as shown in FIG. ), The steel plate 1A is adsorbed and supplied to the next step. Since the steel plates 1B to 1D are already separated, the steel plate 1D can be successively taken out by the suction pad 4 while the mounting table 2 is stopped. As described above, since air enters between the steel plates 1 that have been separated once, even if they are pressed by the suction pad 4, a large adhesion force does not occur again between the steel plates 1, and only the uppermost steel plate 1 is always used. Is adsorbed by the suction pad 4. In addition, if air is blown into the gaps between the steel plates 1 by an air blower (not shown) in the state of FIGS. 1A and 1B, the generation of the adhesion force again can be effectively reduced.

そして、鋼板１Ｄを取り出したら載置台２を上昇させ、図示しないセンサが新たに最上段となった鋼板１Ｅを検出することで載置台２が停止し、以降、図１（ａ）〜（ｄ）に準じた動作を繰り返す。   Then, when the steel plate 1D is taken out, the mounting table 2 is raised, and the mounting table 2 is stopped by detecting the steel plate 1E which is newly provided at the uppermost level by a sensor (not shown), and thereafter, FIGS. 1 (a) to (d). Repeat the operation according to.

以上のような分離方法とすれば、磁力がさほど強くないマグネットセパレータ３でも、鋼板１を確実に分離させることができる。   With the separation method as described above, the steel plate 1 can be reliably separated even with the magnet separator 3 that does not have a strong magnetic force.

また、以上のような分離取り出し装置とすれば、既存の装置に対し、載置台２を下降させる制御を加えるだけで対応可能となるので、汎用性および経済性に優れた装置構成となる。   Moreover, if it is set as the above separation and taking-out apparatus, since it will become possible to respond to the existing apparatus simply by adding control for lowering the mounting table 2, the apparatus configuration is excellent in versatility and economy.

以上、本発明の好適な実施形態について説明した。鋼板積層体の最上段の鋼板を取り出す取り出し部としては、吸着パッド４に限られることはなく、例えば鋼板の縁部を把持する把持機構であってもよい。その他、本発明はその趣旨を逸脱しない範囲で適宜に設計変更が可能である。   The preferred embodiments of the present invention have been described above. The take-out portion for taking out the uppermost steel plate of the steel plate laminate is not limited to the suction pad 4 and may be a gripping mechanism that grips the edge of the steel plate, for example. In addition, the design of the present invention can be changed as appropriate without departing from the spirit of the present invention.
