Description
本発明はセラミックスラドルに関する。 The present invention relates to a ceramic ladle.
セラミックスラドルは溶湯収容室をもつ容器であり、アルミニウム合金等の溶湯を溶湯収容室に収容した状態で、ダイカストマシン等の成形機の鋳型等の溶湯注入部に溶湯を運ぶものである（特許文献１）。 The ceramic ladle is a container having a molten metal storage chamber, and carries the molten metal, such as an aluminum alloy, into a molten metal injection portion of a molding machine such as a die casting machine in a state where the molten metal is stored in the molten metal storage chamber (Patent Document). 1).
従来より、図１２（Ａ）〜（Ｃ）に示すように、ダイカストマシン等の成形機の鋳型等の溶湯注入部にラドル１Ａを運ぶロボットアームが保持する金具５Ａを設け、ラドル１Ａの容器本体部１０Ａの外側に設けた厚肉部３Ａの溝３０Ａにモルタル３５Ａを介して金具５Ａの一部を挿入させ、モルタル３５Ａの固化により金具５Ａを容器本体部１０Ａに取り付けることにしている。ロボットアームは、この金具５Ａを保持してラドル１Ａを溶湯注入部まで運ぶ。 Conventionally, as shown in FIGS. 12A to 12C, a metal fitting 5A held by a robot arm for carrying a ladle 1A is provided in a molten metal injection portion such as a mold of a molding machine such as a die casting machine, and the container body of the ladle 1A A part of the metal fitting 5A is inserted into the groove 30A of the thick part 3A provided outside the part 10A via the mortar 35A, and the metal fitting 5A is attached to the container body 10A by solidifying the mortar 35A. The robot arm holds the metal fitting 5A and carries the ladle 1A to the molten metal injection portion.
しかし図１２（Ａ）〜（Ｃ）に示すラドル１Ａでは、モルタル３５Ａが劣化すると、金具５Ａが容器本体部１０Ａから離脱してしまうおそれがある。更に図１３（Ａ）〜（Ｃ）に示すように、ラドル１Ｂの容器本体部１０Ｂの外側に設けた厚肉部３Ｂにおいて、横方向に延びる貫通孔３０Ｂを形成し、貫通孔３０Ｂに挿入したボルト部材４０Ｂおよびナット部材４４Ｂにより金具５Ｂをラドル１Ｂの容器本体部１０Ｂに取り付けた構造をもつラドル１Ｂが提案されている。 However, in the ladle 1A shown in FIGS. 12A to 12C, when the mortar 35A deteriorates, the metal fitting 5A may be detached from the container body 10A. Further, as shown in FIGS. 13A to 13C, in the thick wall portion 3B provided outside the container main body portion 10B of the ladle 1B, a through hole 30B extending in the lateral direction is formed and inserted into the through hole 30B. There has been proposed a ladle 1B having a structure in which a metal fitting 5B is attached to a container main body 10B of a ladle 1B by a bolt member 40B and a nut member 44B.
しかし貫通孔３０Ｂは、ラドル１Ｂの容器本体部１０Ｂの厚み方向に貫通しており、溶湯収容室２Ｂとその外方とを貫通させている構造である。このため、ラドル１Ｂの溶湯収容室２Ｂに収容されている高温の溶湯が、ラドル１Ｂの貫通孔３０Ｂから矢印Ｘ１方向に漏れるおそれがある。結果として、溶湯収容室２Ｂに収容されている高温の溶湯が、貫通孔３０Ｂを介してラドル１Ｂの外部に漏れるおそれがある。 However, the through hole 30B penetrates in the thickness direction of the container main body 10B of the ladle 1B, and has a structure that penetrates the molten metal storage chamber 2B and the outside thereof. For this reason, there exists a possibility that the high temperature molten metal accommodated in the molten metal storage chamber 2B of the ladle 1B may leak in the arrow X1 direction from the through-hole 30B of the ladle 1B. As a result, the hot molten metal stored in the molten metal storage chamber 2B may leak to the outside of the ladle 1B through the through hole 30B.
更に図１３（Ａ）〜（Ｃ）に示すラドル１Ｂによれば、容器本体部１０Ｂの外側に設けた厚肉部３Ｂにおいて、横方向に延びる貫通孔３０Ｂを形成し、貫通孔３０Ｂに挿入したボルト部材４０Ｂおよびナット部材４４Ｂにより金具５Ｂをラドル１Ｂの容器本体部１０Ｂに取り付けるラドル１Ｂが提案されている。 Furthermore, according to the ladle 1B shown in FIGS. 13A to 13C, a through hole 30B extending in the lateral direction is formed in the thick portion 3B provided outside the container main body portion 10B, and inserted into the through hole 30B. A ladle 1B has been proposed in which a metal fitting 5B is attached to a container body 10B of a ladle 1B by a bolt member 40B and a nut member 44B.
このものによれば、ラドル１Ｂの溶湯収容室２Ｂに収容されている溶湯と、ボルト部材４０Ｂの頭部４２Ｂとが接触するおそれがある。このため、溶湯収容室２Ｂに収容されている溶湯がボルト部材４０Ｂ（頭部４２Ｂを含む）の金属で汚染されるおそれがある。 According to this, there exists a possibility that the molten metal accommodated in the molten metal accommodating chamber 2B of the ladle 1B and the head part 42B of the bolt member 40B may contact. For this reason, there exists a possibility that the molten metal accommodated in the molten metal storage chamber 2B may be contaminated with the metal of the bolt member 40B (including the head portion 42B).
本発明は上記した実情に鑑みてなされたものであり、ロボットアームで保持するためのロボット保持部を容器本体部に簡便に且つ良好に取り付け得、更に、溶湯収容室に収容されている溶湯が溶湯収容室の外部に漏れるおそれを低減させ、溶湯収容室に収容されている溶湯がボルト部材等の取付具の金属等の成分で汚染されるおそれを低減させるのに有利なセラミックスラドルを提供することを課題とする。 The present invention has been made in view of the above circumstances, and a robot holding portion for holding by a robot arm can be easily and satisfactorily attached to a container main body portion. Provided is a ceramic ladle that reduces the risk of leakage to the outside of the molten metal storage chamber, and reduces the risk of the molten metal stored in the molten metal storage chamber being contaminated with components such as metals of fixtures such as bolt members. This is the issue.

（実施形態１）
図１は実施形態１の概念を示す。本実施形態に係るセラミックスラドル１は、溶湯を収容するための溶湯収容室２を有するセラミックス（例えばアルミナ、マグネシア，窒化珪素等）で形成されたカップ形状をなす容器本体部１０と、ロボットアーム（ロボットハンドを含む）が保持するように容器本体部１０に取り付けられたロボット保持部としての金具５とをもつ。
(Embodiment 1)
FIG. 1 shows the concept of the first embodiment. A ceramic ladle 1 according to the present embodiment includes a container body 10 having a cup shape formed of ceramics (for example, alumina, magnesia, silicon nitride, etc.) having a molten metal storage chamber 2 for storing a molten metal, and a robot arm ( And a metal fitting 5 as a robot holding portion attached to the container main body portion 10 so as to hold the robot hand.
図１に示すように、容器本体部１０は有底形状をなしており、底壁部１１と立壁部１２と上面開口１３と先端注入口１４とを有する。容器本体部１０においては、溶湯収容室２は、容器本体部１０の内壁面１０ｉで形成される。容器本体部１０においては、溶湯収容室２の反対側の外壁面１０ｐ側に位置するように容器本体部１０と一体的にセラミックス（容器本体部１０のセラミックスと同一または同系のセラミックス）で形成されたほぼ筒形状の肉厚部３が設けられている。肉厚部３は溶湯収容室２に背向しており、容器本体部１０の外壁面１０ｐに突設されている。複数（２個）の肉厚部３は、互いに間隔ΔＥ（図２参照）ぶん離間させて形成されている。肉厚部３の上面３ｕは平坦化されて金具取付面とされている。肉厚部３においては、セラミックスラドル１の高さ方向（矢印Ｈ方向）に貫通する複数の縦貫通孔３０が、互いに独立して形成されている。縦貫通孔３０は第１開口３１および第２開口３２をもつ。縦貫通孔３０は横断面で円形状が好ましい。縦貫通孔３０に取付具４が挿入されている。 As shown in FIG. 1, the container main body 10 has a bottomed shape, and includes a bottom wall portion 11, a standing wall portion 12, an upper surface opening 13, and a tip injection port 14. In the container main body 10, the molten metal storage chamber 2 is formed by the inner wall surface 10 i of the container main body 10. In the container main body 10, the container main body 10 is integrally formed of ceramics (ceramics the same as or similar to the ceramic of the container main body 10) so as to be positioned on the outer wall surface 10 p side opposite to the molten metal storage chamber 2. Further, a substantially cylindrical thick portion 3 is provided. The thick part 3 faces away from the molten metal storage chamber 2, and protrudes from the outer wall surface 10 p of the container body 10. The plurality of (two) thick portions 3 are formed so as to be separated from each other by an interval ΔE (see FIG. 2). The upper surface 3u of the thick portion 3 is flattened to serve as a bracket mounting surface. In the thick portion 3, a plurality of vertical through holes 30 penetrating in the height direction (arrow H direction) of the ceramic ladle 1 are formed independently of each other. The vertical through hole 30 has a first opening 31 and a second opening 32. The vertical through hole 30 is preferably circular in cross section. The fixture 4 is inserted into the vertical through hole 30.
図２に示すように、取付具４は、縦貫通孔３０に挿入された金属またはセラミックス（例えばアルミナ、窒化珪素、炭化珪素、ムライト、スピネル）で形成された縦形のボルト部材４０と、ボルト部材４０の雄螺子部に螺着された金属またはセラミックス（例えばアルミナ、窒化珪素、炭化珪素、ムライト、スピネル）で形成された雌螺子部をもつナット部材４４とで形成されている。ロボット保持部は、金属（例えば炭素鋼、ステンレス鋼等の合金鋼、チタン合金、アルミニウム合金）製であり、ロボットアームＲＡが保持する板状の被保持部５１と、被保持部５１と一体的に連接され取付具４により肉厚部３に固定された板状の被固定部５３とを有する。被保持部５１は端面５１ａ，５１ｂ，５１ｃを有する。被固定部５３および被保持部５１は角度θ（図３参照，例えば７０〜１２０°、殊に９０°）曲成されるか、溶接で一体化されており、断面でＬ字形状されている。被固定部５３の平坦な下面５３ｄは肉厚部３の平坦な上面３ｕにあてがわれて当接されているため、高い接触面積をもち、高い保持性を維持している。なお、被保持部５１は複数の透孔５２を有することが好ましい。透孔５２にはロボットアームを取り付けるための取付具（図示せず）が挿入される。これにより被保持部５１はロボットアームに保持される。なお透孔５２は単数でも良い。 As shown in FIG. 2, the fixture 4 includes a vertical bolt member 40 formed of metal or ceramics (for example, alumina, silicon nitride, silicon carbide, mullite, spinel) inserted into the vertical through hole 30, and a bolt member. And a nut member 44 having a female screw portion made of metal or ceramics (for example, alumina, silicon nitride, silicon carbide, mullite, spinel) screwed to 40 male screw portions. Robot holding portion is a metal (such as carbon steel, alloy steel such as stainless steel, titanium alloy, aluminum alloy) is made of a plate-like of the held portion 51 of the robot arm RA is held integrally with the holding portion 51 It is connected to that and a plate-shaped fixed portion 53 fixed to the thick portion 3 by fitting 4. The held portion 51 has end faces 51a, 51b, 51c. A fixed portion 53 and the held portion 51 has an angle theta (see FIG. 3, for example 70 to 120 °, in particular 90 °) either bent, are integrated by welding, and is L-shaped in cross-section . Since the flat lower surface 53d of the fixed portion 53 is abutted is Ategawa the flat upper surface 3u of the thick portion 3 has a high contact area, while maintaining the holding of not higher. Incidentally, the holding portion 51 preferably has a plurality of through holes 52. A fitting (not shown) for attaching the robot arm is inserted into the through hole 52. Thereby, the held portion 51 is held by the robot arm. A single through hole 52 may be used.
図２に示すように、ナット部材４４は、容器本体部１０の肉厚部３の下面３ｄにあてがわれて当接されている。ボルト部材４０の頭部４２は、金具５の被固定部５３の上面５３ｕにあてがわれている。ボルト部材４０の頭部４２は薄肉化されており、頭部４２の高さ寸法Ｈ１は、ナット部材４４の高さ寸法Ｈ２およびボルト部材４０のピッチ径Ｄ１よりも小さくされている。これにより頭部４２の上面４２ｕの上方の空間４６が大きくされ、ロボットアームが金具５の被保持部５１を掴むための部分の面積が増加されている。これによりロボットアームがセラミックスラドル１を掴み易くなっている。 As shown in FIG. 2, the nut member 44 is applied to and contacted with the lower surface 3 d of the thick portion 3 of the container body 10. Head 42 of the bolt member 40 is Ategawa the upper surface 53u of the fixed portion 53 of the bracket 5. The head part 42 of the bolt member 40 is thinned, and the height dimension H1 of the head part 42 is smaller than the height dimension H2 of the nut member 44 and the pitch diameter D1 of the bolt member 40. Thus above the top surface 42u of the space 46 of the head 42 is large, the area of the portion for a robot arm to grip the held portion 51 of the fitting 5 is increased. As a result, the robot arm can easily grasp the ceramic ladle 1.
ラドル１の容器本体部１０の溶湯収容室２内に保持炉の溶湯を収容させるときには、ロボットアームで金具５の被保持部５１を掴んだ状態で、容器本体部１０を傾斜させつつ保持炉の溶湯に浸漬させる。これにより保持炉の溶湯をラドル１の上面開口１３から溶湯収容室２に所要量収容させる。ロボットアームが動作するため、上記したように溶湯を溶湯収容室２に収容したラドル１をダイカストマシン等の成形機の鋳型等の溶湯注入部に運ぶ。ロボットアームが動作すれば、ラドル１の容器本体部１０の溶湯収容室２内の溶湯を溶湯注入部に注入させる。溶湯としては、例えばアルミニウム合金、亜鉛合金、銅合金、スズ合金、場合によっては、鉄合金等の溶湯が例示される。図１および図２から理解できるように、ボルト部材４０およびナット部材４４は、ラドル１の容器本体部１０の外壁面１０ｐ側に配置されている。ここで、溶湯収容室２に収容されている溶湯は、基本的にはボルト部材４０およびナット部材４４に接触しないため、溶湯収容室２に収容されている溶湯がボルト部材４０およびナット部材４４によって汚染されるおそれが低減される。 When to accommodate melt holding furnace to the ladle 1 of the molten metal receiving chamber 2 of the container body 10, while grabbing the held portion 51 of the fitting 5 in the robot arm, the holding furnace while inclining the container body 10 Soak in molten metal. As a result, the required amount of molten metal in the holding furnace is stored in the molten metal storage chamber 2 from the upper surface opening 13 of the ladle 1. Since the robot arm operates, the ladle 1 containing the molten metal in the molten metal storage chamber 2 as described above is carried to a molten metal injection portion such as a mold of a molding machine such as a die casting machine. When the robot arm operates, the molten metal in the molten metal storage chamber 2 of the container body 10 of the ladle 1 is injected into the molten metal injection part. Examples of the molten metal include aluminum alloys, zinc alloys, copper alloys, tin alloys, and in some cases, molten metals such as iron alloys. As can be understood from FIGS. 1 and 2, the bolt member 40 and the nut member 44 are disposed on the outer wall surface 10 p side of the container body 10 of the ladle 1. Here, since the molten metal accommodated in the molten metal storage chamber 2 basically does not contact the bolt member 40 and the nut member 44, the molten metal stored in the molten metal storage chamber 2 is moved by the bolt member 40 and the nut member 44. The risk of contamination is reduced.
またラドル１の使用時には、条件によっては、溶湯がボルト部材４０付近や金具５付近にこれらの上側からかかるようなときがある。このようなときであっても、ナット部材４４は肉厚部３に隠蔽されつつ、ボルト部材４０の下端４０ｄ側に配置されている。このため、矢印Ｗ１方向にかかる溶湯がナット部材４４にかかることが抑制される。ひいてはナット部材４４およびボルト部材４０が溶湯の凝固で固着してしまうことが抑制される。よって、セラミックスラドル１のメンテナンス時にナット部材４４およびボルト部材４０を分離させることが期待され、ひいては金具５の交換に適する。 Further, when the ladle 1 is used, depending on conditions, the molten metal may be applied to the vicinity of the bolt member 40 or the metal fitting 5 from above. Even in such a case, the nut member 44 is arranged on the lower end 40d side of the bolt member 40 while being concealed by the thick portion 3. For this reason, the molten metal applied in the direction of the arrow W <b> 1 is suppressed from being applied to the nut member 44. As a result, the nut member 44 and the bolt member 40 are prevented from being fixed due to solidification of the molten metal. Therefore, it is expected that the nut member 44 and the bolt member 40 are separated at the time of maintenance of the ceramic ladle 1, which is suitable for replacement of the metal fitting 5.
（実施形態２）
図４は実施形態２の概念を示す。本実施形態は実施形態１と基本的には同様の構成、同様の作用効果を有する。ボルト部材４０の頭部４２は、肉厚部３の下面３ｄにあてがわれている。ナット部材４４は、容器本体部１０の肉厚部３の上面３ｕ上の金具５にあてがわれて当接された状態で、ボルト部材４０の先端部４０ｅに螺着される。ここで、ナット部材４４は薄肉化されており、ナット部材４４の高さ寸法Ｈ２は、頭部４２の高さ寸法Ｈ１およびボルト部材４０のピッチ径Ｄ１よりも小さくされている。これによりナット部材４４の上面４４ｕの上方の空間４６が大きくされている。よって、ロボットアームが金具５の被保持部５１を掴むための部分の面積が増加されている。これによりロボットアームがセラミックスラドル１を掴み易くなっている。
(Embodiment 2)
FIG. 4 shows the concept of the second embodiment. This embodiment has basically the same configuration and the same function and effect as the first embodiment. The head portion 42 of the bolt member 40 is applied to the lower surface 3 d of the thick portion 3. The nut member 44 is screwed to the tip end portion 40 e of the bolt member 40 in a state where the nut member 44 is applied to the metal fitting 5 on the upper surface 3 u of the thick portion 3 of the container body 10 and is in contact therewith. Here, the nut member 44 is thinned, and the height dimension H2 of the nut member 44 is smaller than the height dimension H1 of the head part 42 and the pitch diameter D1 of the bolt member 40.

ロボット保持部５は金属製であり、ロボットアームが保持する板状の被保持部５１と、被保持部５１と一体的に連接され取付具４により肉厚部３に固定された板状の被固定部５３とを有する。被固定部５３および被保持部５１は、断面でＬ字形状されている。ナット部材４４は、容器本体部１０の肉厚部３の下面３ｄにあてがわれて当接されている。ボルト部材４０の頭部４２は金具５の被固定部５３の上面５３ｕにあてがわれている。ボルト部材４０の頭部４２は薄肉化されており、頭部４２の高さ寸法Ｈ１はナット部材４４の高さ寸法Ｈ２およびボルト部材４０のピッチ径Ｄ１よりも小さくされている。これにより頭部４２の上面４２ｕの上方の空間４６が大きくされ、ロボットアームが金具５の被保持部５１を掴む面積が増加されている。これによりロボットアームがセラミックスラドル１を掴み易くなっている。 Robot holding unit 5 is made of metal, the plate-shaped of the held portion 51 of the robot arm is held, the held portion 51 integrally with articulated thick portion 3 which is fixed to the plate by fitting 4 And a fixing portion 53. A fixed portion 53 and the held portion 51 is L-shaped in cross-section. The nut member 44 is applied to and contacted with the lower surface 3d of the thick portion 3 of the container body 10. Head 42 of the bolt member 40 is Ategawa the upper surface 53u of the fixed portion 53 of the bracket 5. The head portion 42 of the bolt member 40 is thinned, and the height dimension H1 of the head portion 42 is smaller than the height dimension H2 of the nut member 44 and the pitch diameter D1 of the bolt member 40. Thus above the top surface 42u of the space 46 of the head 42 is large, the robot arm is increased the area to grip the held portion 51 of the bracket 5. As a result, the robot arm can easily grasp the ceramic ladle 1.
ラドル１内に保持炉８の溶湯８０を収容させるときには、ロボットアームの動作により、図９に示すようにラドル１を傾斜させ、酸化膜破砕部１８３を最下側に位置させる。そして、保持炉８の溶湯８０の湯面８１に浮遊している酸化膜８５に酸化膜破砕部１８３を当てる。このとき溶湯８０の湯面８１に浮遊している酸化膜８５はラドル１の酸化膜破砕部１８３により破砕され、溶湯露出面８２が形成される。さらに、図１０に示すように、ラドル１を傾斜させたまま、溶湯８０内に浸漬させる。すると、図１０から理解できるように、保持炉８の溶湯８０は、ラドル１の第２溶湯注入口１８２、溶湯通路１７３、第１溶湯注入口１８１を介して溶湯収容室２に進入し収容される。 When the molten metal 80 of the holding furnace 8 is accommodated in the ladle 1, the ladle 1 is inclined as shown in FIG. 9 by the operation of the robot arm, and the oxide film crushing portion 183 is positioned on the lowermost side. Then, the oxide film crushing portion 183 is applied to the oxide film 85 floating on the molten metal surface 81 of the molten metal 80 of the holding furnace 8. At this time, the oxide film 85 floating on the molten metal surface 81 of the molten metal 80 is crushed by the oxidized film crushing portion 183 of the ladle 1 to form a molten metal exposed surface 82. Further, as shown in FIG. 10, the ladle 1 is immersed in the molten metal 80 while being inclined. Then, as can be understood from FIG. 10, the molten metal 80 of the holding furnace 8 enters the molten metal storage chamber 2 through the second molten metal inlet 182, the molten metal passage 173, and the first molten metal inlet 181 of the ladle 1 and is stored therein. The
このとき図１０から理解できるように、ラドル１の第２溶湯注入口１８２は、保持炉８の溶湯８０の湯面８１に浮遊している酸化膜８５よりも深く浸漬される。このため、溶湯８０の湯面に浮遊している酸化膜８５は、第２溶湯注入口１８２、溶湯通路１７３、第１溶湯注入口１８１を介して溶湯収容室２に進入することが抑制される。このため酸化膜８５が成形品に混入することが抑制される。基本的には、保持炉８に保持されている溶湯８０が、第２溶湯注入口１８２、溶湯通路１７３、第１溶湯注入口１８１を介して溶湯収容室２に進入して収容される。その後、ロボットアームの動作によりラドル１を保持炉の溶湯８０の湯面８１から持ち上げる。さらに、ロボットアームが動作するため、上記したように溶湯８０を溶湯収容室２に収容したラドル１をダイカストマシン等の成形機の鋳型等の溶湯注入部に運ぶ。ロボットアームがさらに動作すれば、ラドル１の容器本体部１０の溶湯収容室２内の溶湯８０を溶湯注入部に注入させることができる。 At this time, as can be understood from FIG. 10, the second molten metal inlet 182 of the ladle 1 is immersed deeper than the oxide film 85 floating on the molten metal surface 81 of the molten metal 80 of the holding furnace 8. Therefore, the oxide film 85 floating on the molten metal surface of the molten metal 80 is prevented from entering the molten metal storage chamber 2 through the second molten metal inlet 182, the molten metal passage 173, and the first molten metal inlet 181. . For this reason, it is suppressed that the oxide film 85 mixes in a molded article. Basically, the molten metal 80 held in the holding furnace 8 enters and is accommodated in the molten metal storage chamber 2 via the second molten metal inlet 182, the molten metal passage 173, and the first molten metal inlet 181. Thereafter, the ladle 1 is lifted from the molten metal surface 81 of the molten metal 80 of the holding furnace by the operation of the robot arm. Further, since the robot arm operates, the ladle 1 in which the molten metal 80 is accommodated in the molten metal storage chamber 2 as described above is carried to a molten metal injection portion such as a mold of a molding machine such as a die casting machine. If the robot arm further operates, the molten metal 80 in the molten metal storage chamber 2 of the container body 10 of the ladle 1 can be injected into the molten metal injection section.
