Description

本発明は、溶銑脱硫装置およびその移動台車固定方法に関する。   The present invention relates to a hot metal desulfurization apparatus and a moving cart fixing method thereof.

従来、高炉で得られた溶銑に対して、硫黄分を除去する脱硫処理が行われている。
脱硫処理では、例えば、溶銑を溶銑鍋に取り出し、この溶銑鍋に脱硫剤を添加して撹拌器で攪拌し、溶銑表面に浮上した残滓(スラグ)を排出し、溶銑鍋に脱硫された溶銑を得ている(特許文献1参照)。
特許文献1の溶銑脱硫装置では、台車に載置されて移動可能な溶銑鍋と、台車および溶銑鍋が導入可能な固定式の攪拌装置を用いている。
攪拌装置は、架台で溶銑鍋の上方に支持され、昇降することで攪拌器を溶銑鍋に導入可能である。溶銑鍋および台車は複数設置され、交互に攪拌装置に導入されるとともに、他の溶銑鍋は排滓装置に近接されて残滓を除去される。
Conventionally, desulfurization treatment for removing sulfur content has been performed on hot metal obtained in a blast furnace.
In the desulfurization treatment, for example, the hot metal is taken out into the hot metal ladle, a desulfurizing agent is added to the hot metal ladle, and the mixture is stirred with a stirrer. (See Patent Document 1).
In the hot metal desulfurization apparatus of Patent Document 1, a hot metal ladle mounted on a carriage and movable, and a fixed stirring apparatus into which the carriage and the hot metal ladle can be introduced are used.
The stirring device is supported above the hot metal ladle by a gantry, and the stirrer can be introduced into the hot metal pan by moving up and down. A plurality of hot metal ladles and carts are installed and alternately introduced into the stirring device, and the other hot metal ladle is brought close to the exhausting device to remove residue.

前述した特許文献1では、溶銑鍋および台車を移動させていた。これらの溶銑鍋および台車は、それぞれ収容する溶銑の重量も合わせると極めて大重量となり、駆動装置が大型化するほか、移動経路の補強が必要になる。
これに対し、一対の溶銑鍋を固定的(傾動は可能)に設置し、各溶銑鍋の間で攪拌装置を台車で往復移動させる溶銑脱硫装置が開発されている(特許文献2参照)。
特許文献2の溶銑脱硫装置では、移動する攪拌装置が溶銑鍋に比べて軽量であり、移動機構および移動経路も簡素でよく、設備コストにおいても好ましい。
In patent document 1 mentioned above, the hot metal ladle and the cart were moved. These hot metal ladles and carts are extremely heavy when the weight of the hot metal to be accommodated is also increased, so that the drive device becomes larger and the moving path needs to be reinforced.
On the other hand, a hot metal desulfurization apparatus has been developed in which a pair of hot metal ladles are fixed (can be tilted), and a stirring device is reciprocated between the hot metal ladles by a carriage (see Patent Document 2).
In the hot metal desulfurization apparatus of Patent Document 2, the moving stirrer is lighter than the hot metal ladle, the moving mechanism and the moving path may be simple, and the equipment cost is also preferable.

前述した溶銑脱硫装置においては、攪拌に伴う共振が問題となる。すなわち、大重量の溶銑を攪拌器で駆動する際に、垂直な回転軸を中心とした水平方向の振動が生じる。この振動は、装置の固有振動数近くで大きくなり、装置に影響を及ぼす可能性がある。
とくに、前述した特許文献2の溶銑脱硫装置では、攪拌装置が台車で水平方向に移動可能であり、台車には移動のための機械的な遊びが必要であるため、攪拌時に水平方向の振動が生じ易い。
これに対し、特許文献2では、攪拌時の振動を抑制するために、台車の両側に複数の固定装置を設置し、台車をその移動経路に対して固定している。
しかし、特許文献2で用いられる固定装置は、例えば垂直方向に凹凸嵌合することで水平方向の位置規制を行うストッパなどであり、嵌合状態においても僅かな遊びが残る。このため、攪拌時の振動に対して十分な抑止効果が得られていなかった。
In the hot metal desulfurization apparatus described above, resonance due to stirring is a problem. That is, when a large amount of hot metal is driven by a stirrer, horizontal vibration about a vertical rotation axis is generated. This vibration increases near the natural frequency of the device and can affect the device.
In particular, in the hot metal desulfurization apparatus of Patent Document 2 described above, the stirring device can be moved in the horizontal direction by the carriage, and the carriage needs mechanical play for movement. It is likely to occur.
On the other hand, in patent document 2, in order to suppress the vibration at the time of stirring, the several fixing device is installed in the both sides of the trolley | bogie, and the trolley | bogie is being fixed with respect to the movement path | route.
However, the fixing device used in Patent Document 2 is, for example, a stopper that regulates the position in the horizontal direction by engaging the projections and depressions in the vertical direction, and slight play remains even in the fitted state. For this reason, a sufficient deterrent effect against vibration during stirring has not been obtained.

本発明の目的は、攪拌装置の移動台車を確実に固定できる溶銑脱硫装置およびその移動台車固定方法を提供することにある。   The objective of this invention is providing the hot metal desulfurization apparatus which can fix the moving trolley of a stirring apparatus reliably, and its moving trolley fixing method.

本発明の溶銑脱硫装置は、複数の溶銑鍋装置を結ぶ移動経路と、攪拌装置を支持しかつ前記移動経路に沿って移動可能な移動台車と、前記移動台車と前記移動経路との間に設置された複数のストッパ機構と、を有し、前記ストッパ機構は、前記移動経路に固定された固定側部材と、前記移動台車に設置された移動側部材と、前記移動側部材を前記固定側部材に当接させる当接機構と、を有し、複数の前記ストッパ機構のうち少なくとも2組の一対となる前記ストッパ機構が交差方向に配置され、それぞれの一対となる前記ストッパ機構は、各々の前記移動側部材前記固定側部材に当接させることによる前記移動台車の水平面内の移動を規制する方向が互いに逆向きに配置されていることを特徴とする。 The hot metal desulfurization apparatus of the present invention is installed between a moving path connecting a plurality of hot metal ladle apparatuses, a moving carriage that supports the stirring apparatus and is movable along the moving path, and the moving carriage and the moving path. A plurality of stopper mechanisms, wherein the stopper mechanism is a fixed side member fixed to the moving path, a moving side member installed on the moving carriage, and the moving side member is fixed to the fixed side member. An abutment mechanism that abuts against each other, and at least two pairs of the stopper mechanisms among the plurality of the stopper mechanisms are arranged in a crossing direction, and each of the pair of the stopper mechanisms includes the direction to restrict the movement in the horizontal plane of the movable carrier by bringing into contact a movable member on the fixed member are disposed opposite to each other and said.

本発明では、攪拌装置が移動台車によって移動経路に沿って移動され、複数の溶銑鍋装置のいずれかに対して配置された状態で、その溶銑鍋の攪拌を行うことができる。
攪拌を行う際には、ストッパ機構の当接機構により移動側部材を固定側部材に当接させ、移動台車を移動経路に対して固定する。
複数のストッパ機構のうち少なくとも一対は、移動側部材の固定側部材に対する当接方向の水平成分が互いに逆向きとされている。
このため、一対のストッパ機構のうち、一方のストッパ機構の移動側部材を固定側部材に当接させた際に、各々の間に遊びが残っていたとしても、他方のストッパ機構の移動側部材を固定側部材に当接させることで、残っていた遊びを解消させることができる。
従って、本発明によれば、移動台車と移動経路との間の遊びを解消し、攪拌装置の移動台車を確実に固定することができ、攪拌時の振動を確実に抑制することができる。
In the present invention, the hot metal ladle can be stirred in a state in which the stirring device is moved along the moving path by the moving carriage and is arranged with respect to any of the hot metal ladle devices.
When agitation is performed, the moving member is brought into contact with the fixed member by the contact mechanism of the stopper mechanism, and the moving carriage is fixed to the moving path.
In at least one pair of the plurality of stopper mechanisms, the horizontal components in the contact direction of the movable member with respect to the fixed member are opposite to each other.
For this reason, even if there is play remaining between each of the pair of stopper mechanisms when the moving side member of one stopper mechanism is brought into contact with the fixed side member, the moving side member of the other stopper mechanism The remaining play can be eliminated by contacting the fixed member with the fixed member.
Therefore, according to this invention, the play between a moving trolley and a movement path | route can be eliminated, the moving trolley | bogie of a stirring apparatus can be fixed reliably, and the vibration at the time of stirring can be suppressed reliably.

移動側部材または固定側部材の移動機構、または、圧入部材を移動させる駆動機構としては、例えば油圧シリンダなどが利用できるほか、モータと歯車機構により往復駆動を行うものが利用できる。
As a contact mechanism of the stopper mechanism, one of the moving side member and the fixed side member is moved along the contact direction from a state of being opposed to each other, so that the moving side member directly contacts the fixed side member. A contact configuration is available. Further, by using a press-fitting member different from the moving side member or the fixed side member, driving the press-fitting member in a direction crossing the contact direction, and press-fitting the gap between the moving side member and the fixed side member, It is good also as a structure which makes a movement side member contact | abut indirectly with respect to a fixed side member.
As a moving mechanism for the moving side member or the fixed side member, or a driving mechanism for moving the press-fitting member, for example, a hydraulic cylinder or the like can be used, and a mechanism that reciprocates by a motor and a gear mechanism can be used.

本発明では、一対のストッパ機構の各々の固定側部材の間に、移動台車およびこれに設置された一対の移動側部材が配置される。その結果、移動台車は、2つの移動側部材を一対の固定側部材に挟まれた状態とされ、確実に固定することができる。
In the hot metal desulfurization apparatus of the present invention, it is preferable that the pair of stopper mechanisms arranged in the opposite directions are arranged such that the fixed side members face each other.
In the present invention, the movable carriage and the pair of moving side members installed on the movable carriage are disposed between the fixed side members of the pair of stopper mechanisms. As a result, the movable carriage is in a state where the two movable members are sandwiched between the pair of stationary members, and can be reliably fixed.

本発明の溶銑脱硫装置において、逆向きに配置された一対の前記ストッパ機構は、各々の前記固定側部材が互いに背中合わせに配置されていることが好ましい。
本発明では、一対のストッパ機構の各々の固定側部材を、移動台車に設置された一対の移動側部材によって挟みつけることができ、確実に固定することができる。
In the hot metal desulfurization apparatus of the present invention, in the pair of stopper mechanisms arranged in the opposite directions, it is preferable that the fixed side members are arranged back to back.
In the present invention, the fixed side members of the pair of stopper mechanisms can be sandwiched by the pair of moving side members installed on the movable carriage, and can be fixed securely.

本発明の溶銑脱硫装置において、逆向きに配置された一対の前記ストッパ機構は、少なくとも2組が交差方向に設置されていることが好ましい。
本発明では、一対のストッパ機構の2組が交差方向に設置されることで、移動経路に対する移動台車の水平面内の位置を確定し、攪拌装置の垂直な回転軸を中心に生じる水平方向の振動を全て抑制することができる。
In the hot metal desulfurization apparatus of the present invention, it is preferable that at least two pairs of the stopper mechanisms disposed in the opposite directions are installed in the crossing direction.
In the present invention, two sets of a pair of stopper mechanisms are installed in the crossing direction, thereby determining the position in the horizontal plane of the moving carriage with respect to the moving path, and generating horizontal vibration around the vertical rotation axis of the stirring device. Can all be suppressed.

本発明において、交差方向に設置される一対のストッパ機構の2組としては、一対のストッパ機構の一方が移動台車の移動方向で、他方が移動台車の幅方向とすることができる。また、一対のストッパ機構の2組を、それぞれ移動台車の移動方向に対して斜めに配置してもよい。例えば、移動台車の平面形状が矩形であれば、各々の対角線方向に2組を配置することができる。   In the present invention, as two sets of the pair of stopper mechanisms installed in the crossing direction, one of the pair of stopper mechanisms can be the moving direction of the moving carriage and the other can be the width direction of the moving carriage. Moreover, you may arrange | position two sets of a pair of stopper mechanisms diagonally with respect to the moving direction of a mobile trolley, respectively. For example, if the planar shape of the movable carriage is rectangular, two sets can be arranged in each diagonal direction.

本発明の溶銑脱硫装置において、前記固定側部材および前記移動側部材の互いに当接する部分の少なくとも一方が揺動可能に支持されていることが好ましい。
本発明では、移動側部材が固定側部材に当接する際に、互いに所期の接触方向に対していずれかが傾いている場合でも、移動側部材または固定側部材が揺動することで、適切な当接状態を得ることができる。
移動側部材または固定側部材を揺動させる構成としては、ピンジョイントやボールジョイントなどの回動自在な支持構造や、V溝などの溝条嵌合による揺動構造などが適宜利用できる。
In the hot metal desulfurization apparatus of the present invention, it is preferable that at least one of the fixed side member and the movable side member that are in contact with each other is supported so as to be swingable.
In the present invention, when the moving side member abuts on the fixed side member, even if one of them is tilted with respect to the intended contact direction, the moving side member or the fixed side member swings appropriately. Can be obtained.
As a configuration for swinging the moving side member or the fixed side member, a pivotal support structure such as a pin joint or a ball joint, a swinging structure by fitting a groove such as a V groove, or the like can be used as appropriate.

本発明の溶銑脱硫装置において、前記当接機構は、前記移動側部材とともに前記移動台車に設置されていることが好ましい。
本発明では、当接機構および移動側部材は、移動台車に必要な数だけ設置される。一方、固定側部材は、移動台車が停止すべき位置ごとに所定数ずつ設置される。当接機構を固定側部材とともに移動経路側に設置する場合、当接機構も停止位置毎に所定数ずつ設置する必要があるが、本発明では、移動台車に所定数だけ設置すればよく、全体としての数を減らすことができ、構造を簡素化することができる。
In the hot metal desulfurization apparatus of the present invention, it is preferable that the contact mechanism is installed on the moving carriage together with the moving side member.
In the present invention, the contact mechanism and the moving side members are installed as many as necessary for the moving carriage. On the other hand, a fixed number of fixed-side members are installed for each position where the mobile carriage should stop. When the abutment mechanism is installed on the moving path side together with the fixed side member, it is necessary to install a predetermined number of the abutment mechanisms for each stop position. The number can be reduced, and the structure can be simplified.

本発明の溶銑脱硫装置において、前記当接機構は、前記固定側部材と前記移動側部材との間に圧入可能な圧入部材と、前記移動台車に設置されて前記圧入部材を前記移動台車の移動方向と交差する圧入方向へ駆動する駆動機構とを有し、前記移動側部材は、前記圧入方向に平行かつ前記移動台車の移動方向と交差する表面を有し、前記固定側部材は、表面が前記圧入方向に対して傾斜しかつ前記移動台車の移動方向と交差する表面を有することが好ましい。   In the hot metal desulfurization apparatus of the present invention, the abutment mechanism includes a press-fit member that can be press-fitted between the fixed side member and the movable side member, and the press fit member that is installed in the movable carriage and moves the movable carriage. A drive mechanism that drives in a press-fitting direction that intersects the direction, the moving side member has a surface that is parallel to the press-fitting direction and intersects the moving direction of the moving carriage, and the fixed side member has a surface It is preferable to have a surface that is inclined with respect to the press-fitting direction and intersects the moving direction of the movable carriage.

本発明では、当接機構において、駆動機構により圧入部材を移動させることで、圧入部材が固定側部材の傾斜した表面と移動側部材との間に圧入され、移動側部材が圧入部材を介して固定側部材に当接される。
つまり、駆動機構で圧入部材を移動させるだけで、移動側部材と固定側部材とを当接させることができるため、固定側部材および移動側部材は固定的に設置すればよく、強度を確保しつつ、構造を簡素化できる。
In the present invention, in the contact mechanism, the press-fitting member is moved by the drive mechanism, so that the press-fitting member is press-fitted between the inclined surface of the fixed side member and the moving side member, and the moving side member is interposed via the press-fitting member. It abuts on the stationary member.
In other words, the moving side member and the fixed side member can be brought into contact with each other only by moving the press-fitting member with the drive mechanism. Therefore, the fixed side member and the moving side member may be fixedly installed, and the strength is ensured. However, the structure can be simplified.

なお、本発明の溶銑脱硫装置において、当接機構は移動台車側ではなく、移動経路側に設置してもよい。
このような場合、当接機構は、固定側部材と移動側部材との間に圧入可能な圧入部材と、移動経路に設置されて圧入部材を移動台車の移動方向と交差する圧入方向へ駆動する駆動機構とを有し、固定側部材は、圧入方向に平行かつ移動台車の移動方向と交差する表面を有し、移動側部材は、表面が圧入方向に対して傾斜しかつ移動台車の移動方向と交差する表面を有する構成とすればよい。
In the hot metal desulfurization apparatus of the present invention, the contact mechanism may be installed not on the moving carriage side but on the moving path side.
In such a case, the contact mechanism is a press-fit member that can be press-fitted between the fixed-side member and the movable-side member, and is installed in the movement path to drive the press-fit member in a press-fitting direction that intersects the moving direction of the movable carriage. The fixed-side member has a surface parallel to the press-fitting direction and intersecting the moving direction of the moving carriage, and the moving-side member is inclined with respect to the press-fitting direction and the moving direction of the moving carriage A structure having a surface intersecting with the surface may be used.

本発明の溶銑脱硫装置において、前記駆動機構は、前記圧入部材の移動限が、前記圧入部材が前記移動側部材と前記固定側部材との間に圧入される位置よりも十分長く設定されていることが好ましい。
本発明では、駆動機構のストロークに十分余裕が得られるため、圧入部材を固定側部材と移動側部材との間に確実に圧入することができる。つまり、圧入部材が固定側部材と移動側部材との間に圧入される前に、駆動機構が移動限に達すると、圧入部材の十分な圧入ができなくなる可能性があるが、駆動機構の移動限が十分に長く設定されていることで、確実な圧入を行うことができる。
In the hot metal desulfurization apparatus of the present invention, the drive mechanism has the movement limit of the press-fitting member set sufficiently longer than a position where the press-fitting member is press-fitted between the moving side member and the fixed side member. It is preferable.
In the present invention, a sufficient margin is obtained for the stroke of the drive mechanism, so that the press-fitting member can be reliably press-fitted between the stationary member and the moving member. In other words, if the drive mechanism reaches the movement limit before the press-fitting member is press-fitted between the fixed-side member and the movable-side member, there is a possibility that the press-fitting member cannot be fully pressed. By setting the limit sufficiently long, reliable press-fitting can be performed.

本発明の溶銑脱硫装置において、前記圧入部材は円筒形状または周面の一部に平坦部を有する円筒形状であることが好ましい。
本発明では、圧入部材が円筒形状であることで、当接方向が周方向にずれても確実な当接が得られる。一方、周面の一部に平坦部を有する円筒形状を用い、平坦部を移動側部材または固定側部材の表面に沿わせることで、圧入部材の不要な回転などを防止できる。
In the hot metal desulfurization apparatus of the present invention, it is preferable that the press-fitting member has a cylindrical shape or a cylindrical shape having a flat portion at a part of the peripheral surface.
In the present invention, since the press-fitting member has a cylindrical shape, reliable contact can be obtained even if the contact direction is shifted in the circumferential direction. On the other hand, unnecessary rotation of the press-fitting member can be prevented by using a cylindrical shape having a flat portion on a part of the peripheral surface and causing the flat portion to be along the surface of the moving side member or the fixed side member.

図3から図6の各図には、移動台車24の細部が示されている。
図3および図4において、移動台車24は、鋼材で組まれた平面矩形のフレーム240を有し、その中央には攪拌装置20(図1および図2参照)を載置するステージ241を備えている。フレーム240の四隅には、台車枠242を介して前述した車輪25が支持されている。
3 to 6 show details of the moving carriage 24. FIG.
3 and 4, the movable carriage 24 has a flat rectangular frame 240 made of steel, and includes a stage 241 on which the stirring device 20 (see FIGS. 1 and 2) is placed. Yes. The wheels 25 described above are supported at four corners of the frame 240 via a carriage frame 242.

フレーム240の側面には、片側3個ずつ、両側で計6個のストッパ機構40が設置されている。このうち、図3および図4の左方に配置されたストッパ機構40A、同じく右方に配置されたストッパ機構40B、これらの中間に配置されたストッパ機構40Cは、それぞれ同様の構成を有するが、各々の向きが互いに異なる。
図5において、ストッパ機構40Aおよびストッパ機構40Bは、後述する移動側部材41ないし固定側部材44が、移動台車24の移動方向(図3のR方向)に沿って配列されている。
図6において、ストッパ機構40Cは、後述する移動側部材41ないし固定側部材44が、移動台車24の幅方向(図3のW方向)に沿って配列されている。
On the side surface of the frame 240, six stopper mechanisms 40 are installed on each side, three on each side. Among these, the stopper mechanism 40A disposed on the left side in FIGS. 3 and 4, the stopper mechanism 40B disposed on the right side, and the stopper mechanism 40C disposed in the middle of these have the same configuration. Each direction is different from each other.
5, in the stopper mechanism 40A and the stopper mechanism 40B, a moving side member 41 or a fixed side member 44, which will be described later, are arranged along the moving direction of the moving carriage 24 (R direction in FIG. 3).
In FIG. 6, the stopper mechanism 40 </ b> C has a movable side member 41 or a fixed side member 44, which will be described later, arranged along the width direction of the movable carriage 24 (W direction in FIG. 3).

図7には、本実施形態のストッパ機構40が示されている。
ストッパ機構40は、移動台車24に設置された移動側部材41および駆動シリンダ42と、駆動シリンダ42に支持された圧入部材43と、移動経路28に固定された固定側部材44と、を有する。
FIG. 7 shows the stopper mechanism 40 of the present embodiment.
The stopper mechanism 40 includes a moving side member 41 and a driving cylinder 42 installed on the moving carriage 24, a press-fitting member 43 supported by the driving cylinder 42, and a fixed side member 44 fixed to the moving path 28.

移動側部材41は、平板状の鋼材であり、ブラケット411を介して移動台車24のフレーム240に固定されている。
移動側部材41の表面は、ストッパ機構40Cでは、垂直方向に沿いかつ移動台車24の移動方向と交差する方向に配置されている。また、ストッパ機構40A,40Bでは、垂直方向に沿いかつ移動経路28のレール26の連続方向(つまり移動台車24の移動方向)に沿って配置されている。ストッパ機構40A,40Bおよびストッパ機構40Cの配置の相違は、フレーム240に対するブラケット411の向きを変更することで、任意に設定することができる。
The moving side member 41 is a flat steel material, and is fixed to the frame 240 of the moving carriage 24 via a bracket 411.
In the stopper mechanism 40 </ b> C, the surface of the moving side member 41 is arranged along the vertical direction and in a direction intersecting with the moving direction of the moving carriage 24. Further, the stopper mechanisms 40A and 40B are arranged along the vertical direction and along the continuous direction of the rail 26 in the movement path 28 (that is, the movement direction of the movable carriage 24). The difference in the arrangement of the stopper mechanisms 40A, 40B and the stopper mechanism 40C can be arbitrarily set by changing the orientation of the bracket 411 with respect to the frame 240.

駆動シリンダ42は、油圧シリンダなどの往復駆動機構で構成され、進退方向が垂直方向となる状態で、移動台車24のフレーム240に固定されている。
圧入部材43は、円筒形状の鋼材であり、駆動シリンダ42に支持され、その進退により昇降可能である。圧入部材43の周面は、移動側部材41の表面に接触するか、もしくは僅かな間隔で対向して配置されている。
駆動シリンダ42は、圧入部材43の移動限が、後述する圧入部材43が移動側部材41と固定側部材44との間に圧入される位置(図7の実線表示)よりも十分(下方へ)長く設定され、これにより圧入部材43を移動側部材41と固定側部材44との間に十分強い力で圧入することができる。
The drive cylinder 42 is composed of a reciprocating drive mechanism such as a hydraulic cylinder, and is fixed to the frame 240 of the movable carriage 24 in a state where the advance / retreat direction is the vertical direction.
The press-fitting member 43 is a cylindrical steel material, is supported by the drive cylinder 42, and can be moved up and down by its advance and retreat. The peripheral surface of the press-fitting member 43 is in contact with the surface of the moving side member 41 or is disposed so as to face the surface at a slight interval.
In the drive cylinder 42, the movement limit of the press-fitting member 43 is sufficiently (downward) than a position (shown by a solid line in FIG. 7) where a press-fitting member 43 described later is press-fitted between the moving side member 41 and the fixed side member 44. Accordingly, the press-fitting member 43 can be press-fitted between the moving side member 41 and the fixed side member 44 with a sufficiently strong force.

固定側部材44は、移動経路28のブラケット262に支持されたブロック状の鋼材である。ブラケット262は、レール26の支持構造などに固定されている。
固定側部材44には、平板状の鋼材で形成された当接板441が設置されている。
当接板441は、前述した移動側部材41と対向し、かつ上向きに傾斜して配置されている。前述した圧入部材43は、駆動シリンダ42で下降された際に、当接板441に当接し、さらに下降することで移動側部材41と当接板441とで形成されるV字状の隙間に圧入される。その結果、圧入部材43を介して、移動側部材41と固定側部材44とが間接的に当接した状態(図7の実線表示)とされる。
The fixed side member 44 is a block-shaped steel material supported by the bracket 262 of the movement path 28. The bracket 262 is fixed to the support structure of the rail 26 or the like.
The stationary member 44 is provided with a contact plate 441 formed of a flat steel material.
The abutting plate 441 is opposed to the above-described moving-side member 41 and is inclined upward. When the press-fitting member 43 is lowered by the drive cylinder 42, it comes into contact with the contact plate 441, and further descends into a V-shaped gap formed by the moving side member 41 and the contact plate 441. Press fit. As a result, the moving side member 41 and the fixed side member 44 are indirectly in contact with each other via the press-fitting member 43 (shown by a solid line in FIG. 7).

固定側部材44の上端位置は、移動側部材41の下端位置よりも十分下方に配置されている。このため、圧入部材43を引き上げた状態(図7の鎖線表示)では、移動台車24が移動経路28に沿って移動した際に、固定側部材44の上端と移動側部材41の下端とが干渉することはない。   The upper end position of the fixed side member 44 is disposed sufficiently below the lower end position of the moving side member 41. Therefore, in a state where the press-fitting member 43 is pulled up (shown by a chain line in FIG. 7), when the movable carriage 24 moves along the movement path 28, the upper end of the fixed side member 44 and the lower end of the movement side member 41 interfere with each other. Never do.

固定側部材44は、ブラケット262に支持される部分に、垂直な回転軸まわりに回動可能な回動機構442を有する。移動側部材41の表面と、固定側部材44の当接板441の表面の水平方向成分とが平行でない場合、中間に圧入される圧入部材43の周面との間に片当たりなどが生じる可能性がある。しかし、このような場合には、固定側部材44が回動機構442により回動することで、移動側部材41の表面および圧入部材43の周面に追従して当接板441を揺動させ、片当たりを自動的に解消することができる。   The fixed side member 44 has a rotation mechanism 442 that can rotate about a vertical rotation axis at a portion supported by the bracket 262. If the surface of the moving member 41 and the horizontal component of the surface of the contact plate 441 of the fixed member 44 are not parallel, one-side contact may occur between the peripheral surface of the press-fitting member 43 that is press-fitted in the middle. There is sex. However, in such a case, the stationary member 44 is rotated by the rotating mechanism 442 so that the contact plate 441 is swung following the surface of the movable member 41 and the peripheral surface of the press-fitting member 43. It is possible to automatically eliminate the contact.

なお、固定側部材44としては、図7のように、回動機構442により当接板441を揺動するものに限らず、図8のように、断面矩形の溝条と断面半円筒状の突条との組み合わせや、V溝とV形突状との嵌合など、揺動可能な溝条嵌合構造443などを介して当接板441を固定側部材44に揺動自在に支持する構成としてもよい。   As shown in FIG. 7, the fixed-side member 44 is not limited to the member in which the contact plate 441 is swung by the rotation mechanism 442, and as illustrated in FIG. The contact plate 441 is swingably supported on the fixed-side member 44 via a swingable groove fitting structure 443 such as a combination with a protrusion or a fitting between a V groove and a V-shaped protrusion. It is good also as a structure.

本実施形態のストッパ機構40においては、駆動シリンダ42が本発明の駆動機構であり、この駆動シリンダ42、圧入部材43、V字状に配置された移動側部材41および固定側部材44により、本発明の当接機構が構成されている。   In the stopper mechanism 40 of the present embodiment, the drive cylinder 42 is the drive mechanism of the present invention, and the drive cylinder 42, the press-fitting member 43, the moving side member 41 and the fixed side member 44 arranged in a V shape, The contact mechanism of the invention is configured.

なお、本実施形態では、図7のように圧入部材43を円筒形状としたが、圧入部材としては次のような変形が可能である。
図8のように、円筒形状の一部に平坦部431を有する圧入部材43Aを用いてもよい。この場合、平坦部431を移動側部材41の表面に沿わせることにより、圧入部材43Aの不要な回転などを防止できる。
図9のように、駆動シリンダ42の先端に円筒面を有するブロック43Bを支持し、その円筒面を当接板441に当接させてもよい。
図10のように、駆動シリンダ42の先端に傾斜面を有するブロック43Cを支持し、その傾斜面を当接板441に当接させてもよい。
In the present embodiment, the press-fitting member 43 has a cylindrical shape as shown in FIG. 7, but the following modifications are possible as the press-fitting member.
As shown in FIG. 8, a press-fitting member 43A having a flat portion 431 in a part of a cylindrical shape may be used. In this case, unnecessary rotation of the press-fitting member 43A can be prevented by causing the flat portion 431 to be along the surface of the moving member 41.
As shown in FIG. 9, a block 43 </ b> B having a cylindrical surface may be supported at the tip of the drive cylinder 42, and the cylindrical surface may be brought into contact with the contact plate 441.
As shown in FIG. 10, a block 43 </ b> C having an inclined surface may be supported at the tip of the drive cylinder 42, and the inclined surface may be brought into contact with the contact plate 441.

さらに、本実施形態では、固定側部材44において、当接板441を移動経路28に対して揺動可能としたが、移動側部材41において、その当接面が移動台車24に対して揺動可能な構成としてもよく、このような構成でも移動側部材41の固定側部材44に対する当接状態を安定させることができる。   Further, in the present embodiment, in the fixed side member 44, the contact plate 441 can swing with respect to the movement path 28, but in the movement side member 41, the contact surface swings with respect to the moving carriage 24. It is good also as a possible structure, and the contact state with respect to the fixed side member 44 of the movement side member 41 can be stabilized also in such a structure.

As described above, the movable carriage 24 can move along the movement path 28 by traveling on the rail 26 with the wheels 25. Then, in the state where the stopper mechanisms 40A, 40B, and 40C are released, the position restriction on the movable carriage 24 is not performed.
On the other hand, when the stopper mechanisms 40A, 40B, and 40C are brought into contact with each other, the position of the movable carriage 24 is regulated by each.

図11中左側に設置された図中上下に2つのストッパ機構40Aにおいては、圧入部材43が移動側部材41と固定側部材44との間に圧入されることで、移動側部材41と固定側部材44とが図中左向き(R+方向)に当接され、移動台車24のR+方向への移動が規制される。

これら2組のストッパ機構40A,40BのR+方向の当接およびR−方向の当接により、移動台車24の移動経路28に対するR方向の位置が規制される。
そして、移動台車24の中間に設置された図中上下に一対のストッパ機構40Cにおいては、圧入部材43が移動側部材41と固定側部材44との間に圧入されることで、各々において移動側部材41と固定側部材44とが図中上向き(W+方向)および図中下向き(W−方向)に当接され、移動台車24の幅方向(W方向)の位置が規制される。
In the two upper and lower stopper mechanisms 40 </ b> A installed on the left side in FIG. 11, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44. The member 44 is contacted leftward (R + direction) in the figure, and the movement of the movable carriage 24 in the R + direction is restricted.
In the two upper and lower stopper mechanisms 40 </ b> B installed on the right side in FIG. 11, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44. The member 44 is contacted rightward (R-direction) in the figure, and movement of the movable carriage 24 in the R-direction is restricted.
The position in the R direction with respect to the movement path 28 of the movable carriage 24 is regulated by the contact in the R + direction and the contact in the R− direction of the two sets of stopper mechanisms 40A and 40B.
And in the pair of stopper mechanisms 40C vertically installed in the middle of the moving carriage 24, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44, so that each side The member 41 and the fixed-side member 44 are in contact with each other upward (W + direction) in the figure and downward (W− direction) in the figure, and the position of the movable carriage 24 in the width direction (W direction) is restricted.

本実施形態において、ストッパ機構40A,40B,40Cによる移動台車24の位置規制は、次のような手順で行われる。
先ず、ストッパ機構40A,40B,40Cが解除された状態で、移動台車24をR−方向へ移動させ、所定の位置に停止させる。この際の停止位置は、例えば図12右側のストッパ機構40Cにおいて、移動側部材41と固定側部材44とが、互いの間に圧入部材43を圧入可能な間隔の位置とする。
In the present embodiment, the position restriction of the movable carriage 24 by the stopper mechanisms 40A, 40B, and 40C is performed in the following procedure.
First, with the stopper mechanisms 40A, 40B, 40C being released, the movable carriage 24 is moved in the R-direction and stopped at a predetermined position. The stop position at this time is, for example, a position at an interval at which the movable member 41 and the fixed member 44 can press-fit the press-fitting member 43 between them in the stopper mechanism 40C on the right side of FIG.

この状態で、ストッパ機構40Bの圧入部材43を下降させ、圧入部材43を介して移動側部材41と固定側部材44とを当接させる(図12参照)。この際、圧入部材43の圧入は、駆動シリンダ42の進出限よりも手前の所定ストローク位置とされる。圧入部材43の圧入により、移動台車24がR+方向へ僅かに移動することがある。   In this state, the press-fitting member 43 of the stopper mechanism 40B is lowered, and the movable member 41 and the fixed member 44 are brought into contact with each other via the press-fitting member 43 (see FIG. 12). At this time, the press-fitting of the press-fitting member 43 is set to a predetermined stroke position before the advance limit of the drive cylinder 42. Due to the press-fitting of the press-fitting member 43, the movable carriage 24 may slightly move in the R + direction.

次に、ストッパ機構40Aの圧入部材43を下降させ、圧入部材43を介して移動側部材41と固定側部材44とを当接させる(図13参照)。この圧入により、移動台車24がR+方向およびR−方向のいずれにも当接した状態となり、移動台車24の移動経路28に対するR方向の位置が規制される。
この際、圧入部材43の圧入は、駆動シリンダ42の進出限よりも手前の所定ストローク位置とされ、ストッパ機構40A,40Bのいずれにおいても、移動側部材41と固定側部材44とが確実に当接される。
続いて、ストッパ機構40Cの圧入部材43を下降させ、圧入部材43を介して移動側部材41と固定側部材44とを当接させる(図11参照)。これにより、既にR方向の位置が規制されていた移動台車24がW方向にも位置規制され、移動台車24の移動経路28に対する位置が全方向に向けて規制される。
Next, the press-fitting member 43 of the stopper mechanism 40A is lowered, and the movable member 41 and the fixed member 44 are brought into contact with each other through the press-fitting member 43 (see FIG. 13). By this press-fitting, the movable carriage 24 comes into contact with both the R + direction and the R− direction, and the position of the movable carriage 24 in the R direction with respect to the movement path 28 is regulated.
At this time, the press-fitting of the press-fitting member 43 is set to a predetermined stroke position before the limit of advancement of the drive cylinder 42, and the movable member 41 and the fixed member 44 are reliably applied to both the stopper mechanisms 40A and 40B. Be touched.
Subsequently, the press-fitting member 43 of the stopper mechanism 40C is lowered, and the moving side member 41 and the fixed side member 44 are brought into contact with each other through the press-fitting member 43 (see FIG. 11). Thereby, the position of the moving carriage 24 whose position in the R direction has already been restricted is also restricted in the W direction, and the position of the moving carriage 24 relative to the movement path 28 is restricted in all directions.

以上説明した第1実施形態によれば、次のような効果が得られる。
本実施形態では、攪拌装置20が移動台車24によって移動経路28に沿って移動され、複数の溶銑鍋装置10A,10Bのいずれかに対して配置された状態で、その溶銑鍋11の攪拌を行うことができる。
攪拌を行う際には、ストッパ機構40A,40B,40Cの各々において、駆動シリンダ42により圧入部材43を下降させ、移動側部材41と固定側部材44との間に圧入させることで、移動側部材41と固定側部材44とを間接的に当接させ、移動台車24を移動経路28に対して固定することができる。
According to the first embodiment described above, the following effects can be obtained.
In this embodiment, the stirring apparatus 20 is moved along the movement path 28 by the moving carriage 24, and the hot metal ladle 11 is stirred in a state where it is arranged with respect to any of the plurality of hot metal ladle apparatuses 10A and 10B. be able to.
When agitation is performed, in each of the stopper mechanisms 40A, 40B, and 40C, the press-fitting member 43 is lowered by the drive cylinder 42 and press-fitted between the moving-side member 41 and the fixed-side member 44, thereby moving-side member. 41 and the stationary member 44 can be indirectly contacted to fix the movable carriage 24 to the movement path 28.

複数のストッパ機構40A,40B,40Cのうち、両側2組のストッパ機構40A,40Bは、移動経路28に沿ったR方向において互いに一対とされ、移動側部材41の固定側部材44に対する当接方向の水平成分が互いに逆向き(R+方向とR−方向)とされている。また、ストッパ機構40Cにおいては、移動経路28の幅方向であるW方向に一対が設置され、移動側部材41の固定側部材44に対する当接方向の水平成分が互いに逆向き(W+方向とW−方向)とされている。
このため、一対のストッパ機構40A,40B,40Cのうち、一方の移動側部材41を圧入部材43を介して固定側部材44に当接させた際に、各々の間に遊びが残っていたとしても、他方の移動側部材41を固定側部材44に当接させることで、残っていた遊びを解消させることができる。
従って、本実施形態によれば、移動台車24と移動経路28との間の遊びを解消し、攪拌装置20の移動台車24を確実に固定することができ、攪拌時の振動を確実に抑制することができる。
Of the plurality of stopper mechanisms 40A, 40B, 40C, two sets of stopper mechanisms 40A, 40B on both sides are paired with each other in the R direction along the moving path 28, and the contact direction of the moving side member 41 with respect to the fixed side member 44 Are in opposite directions (R + direction and R− direction). Further, in the stopper mechanism 40C, a pair is installed in the W direction that is the width direction of the moving path 28, and the horizontal components in the contact direction of the moving side member 41 with respect to the fixed side member 44 are opposite to each other (W + direction and W−). Direction).
For this reason, when one moving side member 41 of the pair of stopper mechanisms 40A, 40B, and 40C is brought into contact with the fixed side member 44 via the press-fitting member 43, there remains play between them. Also, the remaining play can be eliminated by bringing the other moving side member 41 into contact with the fixed side member 44.
Therefore, according to this embodiment, the play between the moving trolley 24 and the moving path 28 can be eliminated, the moving trolley 24 of the stirring device 20 can be securely fixed, and vibration during stirring is reliably suppressed. be able to.

本実施形態では、移動台車24の両側に一対のストッパ機構40A,40Bが2組、それぞれR方向に逆向きに配置され、移動台車24の両側に一対のストッパ機構40CがW方向に逆向きに配置されている。
これらの各対においては、それぞれの固定側部材44が互いに向かい合わせに配置され、これらの各対の固定側部材44の間に、移動台車24およびこれに設置された一対の移動側部材41が配置される。
その結果、移動台車24は、それぞれ圧入部材43を圧入して互いに当接させることで、2つの移動側部材41を一対の固定側部材44に挟まれた状態とされ、移動経路28に対して確実に固定することができる。
In the present embodiment, two pairs of stopper mechanisms 40A and 40B are arranged on both sides of the moving carriage 24 in the R direction opposite to each other, and the pair of stopper mechanisms 40C on both sides of the moving carriage 24 are opposite in the W direction. Has been placed.
In each of these pairs, the respective fixed side members 44 are arranged so as to face each other, and between each of these pairs of fixed side members 44, there is a movable carriage 24 and a pair of movable side members 41 installed thereon. Be placed.
As a result, the movable carriage 24 is in a state where the two moving side members 41 are sandwiched between the pair of fixed side members 44 by press-fitting the press-fitting members 43 into contact with each other. It can be fixed securely.

本実施形態では、一対のストッパ機構40A,40BがR方向に逆向きに配置され、一対のストッパ機構40CがW方向に逆向きに配置されている。このように、一対のストッパ機構40A,40Bおよび一対のストッパ機構40Cという、2組(2方向)のストッパ機構40の対が交差方向に設置されることで、移動経路28に対する移動台車24の水平面内の位置を確定し、攪拌装置20の垂直な回転軸を中心に生じる水平方向の振動を全て抑制することができる。   In the present embodiment, the pair of stopper mechanisms 40A and 40B are disposed in the reverse direction in the R direction, and the pair of stopper mechanisms 40C are disposed in the reverse direction in the W direction. As described above, the pair of stopper mechanisms 40A and 40B and the pair of stopper mechanisms 40C, ie, two pairs (two directions) of the stopper mechanisms 40 are installed in the crossing direction, so that the horizontal surface of the movable carriage 24 with respect to the movement path 28 is obtained. The horizontal position can be determined, and all horizontal vibrations generated around the vertical rotation axis of the stirring device 20 can be suppressed.

本実施形態では、当接板441を含む固定側部材44を移動経路28に回動機構442を介して回動自在に支持し(図7参照)、あるいは、当接板441を固定側部材44に溝条嵌合構造443を介して嵌め合わせて揺動可能に支持した(図8参照)。このため、移動側部材41が固定側部材44に当接する際に、互いに所期の接触方向に対していずれかが傾いている場合でも、移動側部材41または固定側部材44が揺動することで、適切な当接状態を得ることができる。   In the present embodiment, the fixed side member 44 including the contact plate 441 is rotatably supported on the movement path 28 via the rotation mechanism 442 (see FIG. 7), or the contact plate 441 is fixed to the fixed side member 44. And slidably supported by a groove fitting structure 443 (see FIG. 8). For this reason, when the moving side member 41 abuts on the fixed side member 44, the moving side member 41 or the fixed side member 44 swings even if one of them is inclined with respect to the intended contact direction. Thus, an appropriate contact state can be obtained.

本実施形態では、移動側部材41を固定側部材44に当接させる当接機構としての駆動シリンダ42および圧入部材43を、移動台車24に設置した。つまり、固定側部材44は、移動経路28の移動台車24が停止すべき位置にそれぞれ設置する必要があるが、移動側部材41、駆動シリンダ42および圧入部材43は、移動台車24に最低限の数だけ設置するだけでよい。従って、駆動シリンダ42および圧入部材43については、溶銑脱硫装置1の全体としての設置数を減らすことができ、構造を簡素化することができる。   In the present embodiment, the drive cylinder 42 and the press-fitting member 43 serving as a contact mechanism for bringing the moving side member 41 into contact with the fixed side member 44 are installed in the moving carriage 24. That is, the fixed side member 44 needs to be installed at a position where the moving carriage 24 of the moving path 28 should stop, but the moving side member 41, the drive cylinder 42, and the press-fitting member 43 are the minimum in the moving carriage 24. It is only necessary to install a number. Therefore, about the drive cylinder 42 and the press-fit member 43, the number of installation as the whole hot metal desulfurization apparatus 1 can be reduced, and a structure can be simplified.

本実施形態では、ストッパ機構40(40A,40B,40C)の当接機構として、固定側部材44と移動側部材41との間に圧入可能な圧入部材43と、移動台車24に設置されて圧入部材43を移動台車24の移動方向(R方向)と交差する圧入方向(鉛直方向下向き)へ駆動する駆動シリンダ42とを用い、移動側部材41は、圧入方向に平行かつ移動台車24の移動方向と交差する表面を有し、固定側部材44は、表面が圧入方向に対して傾斜しかつ移動台車24の移動方向と交差する表面をなす当接板441を有するものとした。   In this embodiment, as a contact mechanism of the stopper mechanism 40 (40A, 40B, 40C), a press-fitting member 43 that can be press-fitted between the fixed-side member 44 and the movable-side member 41, and a press-fitted by being installed in the movable carriage 24. Using the drive cylinder 42 that drives the member 43 in the press-fitting direction (vertically downward) intersecting the moving direction (R direction) of the moving carriage 24, the moving-side member 41 is parallel to the press-fitting direction and the moving direction of the moving carriage 24 The fixed-side member 44 has a contact plate 441 that forms a surface whose surface is inclined with respect to the press-fitting direction and intersects the moving direction of the movable carriage 24.

このため、本実施形態では、駆動シリンダ42により圧入部材43を移動させることで、圧入部材43が、固定側部材44の傾斜した当接板441と、移動側部材41の当接板441に対向する表面との間に圧入され、移動側部材41が圧入部材43を介して固定側部材44に当接される。
つまり、駆動シリンダ42で圧入部材43を移動させるだけで、移動側部材41と固定側部材44とを当接させることができ、固定側部材44および移動側部材41は、それぞれ移動経路28および移動台車24に固定的に設置すればよく、強度を確保しつつ、構造を簡素化できる。
For this reason, in this embodiment, the press-fitting member 43 is moved by the drive cylinder 42 so that the press-fitting member 43 faces the inclined contact plate 441 of the stationary member 44 and the contact plate 441 of the movable member 41. The movable side member 41 is brought into contact with the fixed side member 44 via the press-fit member 43.
That is, the moving side member 41 and the fixed side member 44 can be brought into contact with each other only by moving the press-fitting member 43 with the drive cylinder 42. The fixed side member 44 and the moving side member 41 are moved along the moving path 28 and the moving side, respectively. What is necessary is just to install fixedly to the trolley | bogie 24, and a structure can be simplified, ensuring intensity | strength.

本実施形態では、駆動シリンダ42は、圧入部材43の移動限を、圧入部材43が移動側部材41と固定側部材44との間に圧入される位置よりも十分長くした。
これにより、駆動シリンダ42のストロークに十分余裕が得られるため、圧入部材43を固定側部材44と移動側部材41との間に確実に圧入することができる。つまり、圧入部材43が固定側部材44と移動側部材41との間に圧入される前に、駆動シリンダ42が移動限に達すると、圧入部材43の十分な圧入ができなくなる可能性があるが、駆動シリンダ42の移動限が十分に長く設定されることで、確実な圧入を行うことができる。
In the present embodiment, the drive cylinder 42 has the movement limit of the press-fitting member 43 sufficiently longer than the position where the press-fitting member 43 is press-fitted between the moving side member 41 and the fixed side member 44.
As a result, a sufficient margin is obtained for the stroke of the drive cylinder 42, so that the press-fitting member 43 can be reliably press-fitted between the fixed-side member 44 and the moving-side member 41. That is, if the drive cylinder 42 reaches the movement limit before the press-fitting member 43 is press-fitted between the fixed side member 44 and the moving side member 41, there is a possibility that the press-fitting member 43 cannot be fully press-fitted. In addition, when the movement limit of the drive cylinder 42 is set to be sufficiently long, reliable press-fitting can be performed.

本実施形態では、圧入部材43は円筒形状または周面の一部に平坦部を有する円筒形状とすることで、当接方向が周方向にずれても確実な当接が得られる。一方、周面の一部に平坦部を有する円筒形状を用い、平坦部を移動側部材41または固定側部材44の表面に沿わせることで、圧入部材43の不要な回転などを防止できる。   In the present embodiment, the press-fitting member 43 has a cylindrical shape or a cylindrical shape having a flat portion on a part of the peripheral surface, so that reliable contact can be obtained even if the contact direction is shifted in the circumferential direction. On the other hand, an unnecessary rotation of the press-fitting member 43 can be prevented by using a cylindrical shape having a flat portion on a part of the peripheral surface and having the flat portion along the surface of the moving side member 41 or the fixed side member 44.

本実施形態では、移動台車24を移動経路28に対して固定する操作として、移動台車24を移動経路28の溶銑鍋装置10に対応した位置まで移動させ、先ず、一対をなすストッパ機構40A,40Bのうち、一方のストッパ機構40Bにおいて、圧入部材43を下降させて移動側部材41を固定側部材44に当接させて位置決め動作を行い、次に、他方のストッパ機構40Aにおいて、圧入部材43を下降させて移動側部材41を固定側部材44に当接させる固定動作を行うようにした。   In the present embodiment, as an operation for fixing the moving carriage 24 to the moving path 28, the moving carriage 24 is moved to a position corresponding to the hot metal ladle device 10 on the moving path 28, and first, a pair of stopper mechanisms 40A, 40B. Among them, in one stopper mechanism 40B, the press-fitting member 43 is moved down to bring the moving side member 41 into contact with the fixed side member 44 to perform the positioning operation. Next, in the other stopper mechanism 40A, the press-fitting member 43 is moved. A fixing operation of lowering and bringing the moving side member 41 into contact with the fixed side member 44 is performed.

このような位置決め動作および固定動作を順次行う場合、先ず、一方のストッパ機構40Bにおいて移動側部材41を固定側部材44に当接させ、移動経路28に対する移動台車24の位置決めを行うことができる。そして、位置決め動作の際に、移動側部材41および固定側部材44の間に遊びが残っていたとしても、他方のストッパ機構40Aの移動側部材41を固定側部材44に当接させる固定動作により、残っていた遊びを解消させ、この状態で移動経路28に対する移動台車24の固定を行うことができる。
従って、本実施形態では、上述した位置決め動作および固定動作を順次行うことで、移動台車24と移動経路28との間の遊びを解消し、攪拌装置20を載置した移動台車24を確実に固定することができ、攪拌時の振動を確実に抑制することができる。
In the case of sequentially performing such positioning operation and fixing operation, first, the moving side member 41 can be brought into contact with the fixed side member 44 in one stopper mechanism 40B to position the moving carriage 24 with respect to the moving path 28. In the positioning operation, even if there is play between the moving side member 41 and the fixed side member 44, the moving side member 41 of the other stopper mechanism 40A is brought into contact with the fixed side member 44 by the fixing operation. The remaining play can be eliminated, and the movable carriage 24 can be fixed to the movement path 28 in this state.
Therefore, in the present embodiment, the play between the moving carriage 24 and the moving path 28 is eliminated by sequentially performing the positioning operation and the fixing operation described above, and the moving carriage 24 on which the stirring device 20 is placed is securely fixed. And vibration during stirring can be reliably suppressed.

とくに、本実施形態では、移動台車24と移動経路28との間には、一対のストッパ機構40A,40Bが2組、移動台車24の移動方向(R方向)に沿って、移動台車24の両側に設置されており、先ず、一対のストッパ機構40Bの2組で同時に位置決め動作を行い、次に、一対のストッパ機構40Aの2組で同時に固定動作を行うことができる。
このように、一対のストッパ機構40A,40Bの2組を、例えば移動台車24の両側に配置しておくことで、移動経路28を移動する移動台車24に、移動経路28に対する傾き(垂直方向を中心にした回転)があっても、2組の位置決め動作により、移動経路28に対して正しい姿勢で移動台車24を位置決めすることができる。そして、続く固定動作により、正しい姿勢で移動台車24を移動経路28に対して固定することができる。
In particular, in this embodiment, two pairs of stopper mechanisms 40A and 40B are provided between the moving carriage 24 and the moving path 28, along the moving direction (R direction) of the moving carriage 24, on both sides of the moving carriage 24. First, a positioning operation can be performed simultaneously with two sets of the pair of stopper mechanisms 40B, and then a fixing operation can be performed simultaneously with two sets of the pair of stopper mechanisms 40A.
In this way, by arranging two sets of the pair of stopper mechanisms 40A and 40B on both sides of the moving carriage 24, for example, the moving carriage 24 moving along the moving path 28 is inclined with respect to the moving path 28 (in the vertical direction). Even if there is rotation around the center, the moving carriage 24 can be positioned in a correct posture with respect to the moving path 28 by two positioning operations. Then, by the subsequent fixing operation, the movable carriage 24 can be fixed to the movement path 28 in a correct posture.
