Description

本発明は、単結晶棒を育成する育成装置が設けられている単結晶棒育成設備に関する。   The present invention relates to a single crystal rod growing facility provided with a growing apparatus for growing a single crystal rod.

かかる単結晶棒育成設備は、多結晶シリコン等の単結晶棒の原料を収納した坩堝を育成装置の支持台に装填し、装填した坩堝をヒータにて加熱して原料を溶融させ、溶融させた原料に種結晶を浸けてその種結晶を回転させながら引き上げて単結晶棒を育成させ、その単結晶棒を育成装置から取り出して外部に搬出するようにして、シリコン単結晶棒等の単結晶棒を製造するものである。
そして、このような単結晶棒育成設備において、従来では、育成装置の近くに坩堝を育成装置の支持台に坩堝を装填するための手動操作用の坩堝装填装置が設けられており、作業者は、坩堝を載置した坩堝搬送用の台車を押引操作して坩堝を育成装置の近くまで搬送し、坩堝装填装置を手動操作して育成装置の近くまで搬送した坩堝を育成装置の支持台に装填していた(例えば、特許文献1参照。)。
In such a single crystal rod growing facility, a crucible containing a raw material of a single crystal rod such as polycrystalline silicon is loaded on a support base of a growth apparatus, and the loaded crucible is heated with a heater to melt the raw material and melt it. A single crystal rod such as a silicon single crystal rod is obtained by immersing a seed crystal in a raw material and pulling it up while rotating the seed crystal to grow a single crystal rod. Is to be manufactured.
In such single crystal rod growing equipment, conventionally, a crucible loading device for manual operation for loading a crucible near the growing device and a crucible on a support base of the growing device is provided. The crucible carrying the crucible is pushed and pulled to carry the crucible to the vicinity of the growth apparatus, and the crucible loading apparatus is manually operated to carry the crucible to the vicinity of the growth apparatus. It was loaded (see, for example, Patent Document 1).

特開平7−172975号公報JP 7-172975 A

しかしながら、原料を収容した坩堝や単結晶棒は重量物であるため、坩堝の台車による搬送や坩堝装填装置による坩堝の装填は作業者にとって負担が大きいものであり、作業者の負担の軽減が求められていた。
また、支持台に対して適正な位置から水平方向にずれた位置に坩堝が装填されると、その坩堝の周囲に備えられたヒータにて坩堝を加熱するときに坩堝の温度の均一性が低下し、育成された単結晶棒の品質が低下するため、支持台に対して適正な位置に坩堝を装填することが望まれるが、従来では、熟練した作業者が治具等を利用して坩堝を支持台に対して適正な位置に装填しており、坩堝の装填が煩わしいものであった。
However, since crucibles and single crystal rods containing raw materials are heavy, transporting the crucible with a cart or loading the crucible with a crucible loading device is a heavy burden on the worker, and it is necessary to reduce the burden on the worker. It was done.
In addition, when the crucible is loaded at a position shifted from an appropriate position with respect to the support base in the horizontal direction, the temperature uniformity of the crucible decreases when the crucible is heated by the heater provided around the crucible. However, since the quality of the grown single crystal rod deteriorates, it is desirable to load the crucible at an appropriate position with respect to the support base. Conventionally, a skilled worker uses a jig or the like to crucible. Was loaded at an appropriate position with respect to the support base, and loading of the crucible was troublesome.

本発明は、上記実状に鑑みて為されたものであって、その目的は、作業者の負担を軽減でき且つ坩堝を支持台に対して適正な位置に自動的に装填することができる単結晶棒育成設備を提供する点にある。   The present invention has been made in view of the above situation, and its purpose is to reduce the burden on the operator and to automatically load the crucible at an appropriate position with respect to the support base. The point is to provide equipment for growing rods.

本発明にかかる単結晶棒育成設備は、単結晶棒を育成する育成装置が設けられているものであって、その第1特徴構成は、
前記単結晶棒の原料を収納した坩堝を受け取る坩堝受取位置と前記育成装置に坩堝を装填する坩堝装填位置とに走行自在な坩堝搬送車が設けられ、前記育成装置が、上方側から前記坩堝が装填される支持台を備えて構成され、前記坩堝搬送車の昇降台に、前記坩堝を支持する坩堝支持体を前記昇降台上に位置させた搬送用位置と前記育成装置が位置する側に位置させた装填用位置とに移動させる移動操作手段が備えられ、前記坩堝搬送車を前記坩堝装填位置に走行させ且つ前記昇降台を前記坩堝支持体にて支持される前記坩堝が前記支持台より上方に位置する高さに昇降させる第1移動動作、この第1移動動作完了後に前記移動操作手段にて前記坩堝支持体を前記搬送用位置から前記装填用位置に移動させる第2移動動作、及び、この第2移動動作完了後に前記昇降台を前記坩堝が前記支持台に装填される高さに下降させる第3移動動作により、前記坩堝を前記支持台に載置させるべく、前記坩堝搬送車の走行作動、前記昇降台の昇降作動、及び、前記移動操作手段の移動作動を制御する制御手段と、前記第3移動動作を実行するときに前記坩堝支持体を水平方向に自由移動する状態に支持する支持手段と、前記第3移動動作により下降される前記坩堝支持体を水平方向に案内して前記支持台に対する適正位置に位置決めする案内位置決め手段とを備えて構成されている点にある。
The single crystal rod growing facility according to the present invention is provided with a growing apparatus for growing a single crystal rod, and the first characteristic configuration thereof is:
A crucible transport vehicle is provided at a crucible receiving position for receiving a crucible containing the raw material of the single crystal rod and a crucible loading position for loading the crucible into the growing apparatus, and the growing apparatus is connected to the crucible from above. It is provided with a support base to be loaded, and is located on the lifting platform of the crucible transport vehicle on the side where the crucible support for supporting the crucible is positioned on the lifting platform and the growth device is located. Moving operation means for moving the crucible carrier to the crucible loading position, and the crucible for supporting the lifting platform supported by the crucible support above the support base. A first moving operation for moving up and down to a height located at a position, a second moving operation for moving the crucible support from the transfer position to the loading position by the moving operation means after the completion of the first moving operation, and This second transition After the operation is completed, the crucible transport vehicle is moved and moved up and down in order to place the crucible on the support base by a third moving operation for lowering the lift base to a height at which the crucible is loaded on the support base. Control means for controlling the lifting operation of the table and the movement operation of the moving operation means, and a support means for supporting the crucible support in a state of free movement in the horizontal direction when the third movement operation is executed, And a guide positioning means for guiding the crucible support lowered by the third movement operation in a horizontal direction and positioning the crucible support at an appropriate position with respect to the support base.

すなわち、制御手段が、坩堝搬送車の走行作動、昇降台の昇降作動、及び、移載操作手段の移動作動を制御して、第1移動動作により、坩堝搬送車を坩堝装填位置に走行させ且つ昇降台を坩堝が育成装置の支持台より上方に位置する高さに昇降させ、次に、第2移動動作により、移動操作手段にて坩堝支持体を搬送用位置から装填用位置に移動させ、次に、第3移動動作により、昇降台を坩堝が支持台に装填される高さに下降させることによって、坩堝を育成装置の支持台に装填させることができるので、坩堝搬送車にて坩堝を育成装置の支持台に自動的に装填することができる。
そして、第3移動動作において昇降台を下降させるときには、支持手段にて水平方向に自由移動する状態に支持されている坩堝支持体を、案内位置決め手段にて水平方向に案内して支持台に対して適正位置に位置決めされる。よって、坩堝搬送車の位置が坩堝装填位置から走行方向にずれている場合や坩堝支持体が装填用位置から坩堝支持体の移動方向にずれている場合等により、昇降台を下降させて坩堝を装填するときに坩堝支持体が適正位置の上方側で水平方向にずれていたとしても、支持手段と案内位置決め手段とによって坩堝支持体を適正位置に案内して位置決めすることができるため、坩堝を支持台に対して適正な位置に装填することができる。
従って、坩堝搬送車にて坩堝を育成装置の支持台に自動的に装填することができるので、作業者の負担を軽減することができ、しかも、昇降台を下降させて坩堝を装填するときに坩堝支持体が適正位置の上方側で水平方向にずれていたとしても、支持手段と案内位置決め手段とによって坩堝を支持台に対して適正な位置に装填することができるものとなり、もって、作業者の負担を軽減でき且つ坩堝を支持台に対して適正な位置に自動的に装填することができる単結晶棒育成設備を提供することができるに至った。
That is, the control means controls the traveling operation of the crucible transport vehicle, the lifting operation of the lifting platform, and the moving operation of the transfer operation means, and the first moving operation causes the crucible transport vehicle to travel to the crucible loading position and The lifting platform is moved up and down to a height where the crucible is located above the support platform of the growing apparatus, and then the second moving operation is used to move the crucible support from the transfer position to the loading position by the moving operation means. Next, the crucible can be loaded on the support base of the growing apparatus by lowering the lifting platform to a height at which the crucible is loaded on the support base by the third movement operation. It can be automatically loaded on the support base of the growing device.
Then, when lowering the lifting platform in the third movement operation, the crucible support that is supported in a state of free movement in the horizontal direction by the support means is guided in the horizontal direction by the guide positioning means and is moved relative to the support table. Is positioned at the appropriate position. Therefore, when the position of the crucible transport vehicle is deviated from the crucible loading position in the traveling direction or the crucible support is deviated from the loading position in the moving direction of the crucible support, the lifting platform is lowered to remove the crucible. Even when the crucible support is displaced horizontally above the proper position when loading, the crucible support can be guided to the proper position and positioned by the support means and the guide positioning means. It can be loaded at an appropriate position with respect to the support base.
Therefore, since the crucible can be automatically loaded on the support base of the growing apparatus by the crucible transporter, the burden on the operator can be reduced, and when the crucible is loaded by lowering the lifting platform. Even if the crucible support is displaced in the horizontal direction above the proper position, the support means and the guide positioning means can load the crucible at the proper position with respect to the support base, so that the operator It is possible to provide a single crystal rod growing facility that can reduce the burden of the crucible and can automatically load the crucible at an appropriate position with respect to the support base.

本発明にかかる単結晶棒育成設備の第2特徴構成は、第1特徴構成において、前記坩堝支持体が、前記坩堝の上部を吊り下げ支持自在に構成され、前記昇降台に、前記坩堝を載置する坩堝載置体を前記昇降台上に位置させた載置搬送位置と前記坩堝の坩堝搬入箇所が位置する側に位置させた掬い用位置とに移動させるフォーク装置が備えられ、前記坩堝搬送位置に位置する前記坩堝載置体に載置された前記坩堝の上部を前記坩堝支持体にて保持するべく前記坩堝支持体と前記坩堝載置体とを上下方向に接近させた接近状態と、保持した前記坩堝を吊り下げ支持するべく前記坩堝支持体と前記坩堝載置体とを上下方向に離間させた離間状態とに切り換える切換操作手段が設けられ、前記制御手段が、前記坩堝搬送車を前記坩堝受取位置に走行させて、前記坩堝搬入箇所に位置する坩堝を掬い取り、次に、前記坩堝支持体と前記坩堝載置体とを前記近接状態に切り換えて前記坩堝支持体にて前記坩堝を保持した後に、前記坩堝支持体と前記坩堝載置体とを離間状態に切り換えて前記坩堝支持体にて前記坩堝を吊り下げ支持するように、前記坩堝搬送車の走行作動、前記昇降台の昇降作動、前記坩堝支持体の作動、前記フォーク装置の出退作動、及び、前記切換操作手段の切換作動を制御するように構成されている点にある。   A second characteristic configuration of the single crystal rod growing facility according to the present invention is the first characteristic configuration, wherein the crucible support is configured to be able to suspend and support an upper part of the crucible, and the crucible is mounted on the lifting platform. A crucible carrying body for moving the crucible placing body to a placing and carrying position located on the lifting platform and a scooping position located on the crucible carrying position of the crucible; An approaching state in which the crucible support and the crucible mounting body are brought close to each other in the vertical direction so as to hold the upper part of the crucible mounted on the crucible mounting body located at the position by the crucible support; Switching operation means is provided for switching the crucible support and the crucible mounting body to a separated state in the vertical direction so as to suspend and support the held crucible, and the control means controls the crucible transport vehicle. Traveled to the crucible receiving position The crucible located at the crucible loading position is scraped, and then the crucible support and the crucible mounting body are switched to the proximity state, and the crucible support is held by the crucible support. The crucible carrier moving operation, the lifting platform elevating operation, the crucible support body so that the support body and the crucible mounting body are switched to a separated state and the crucible support body is suspended and supported by the crucible support body. The fork device is configured to control the operation of the fork device and the switching operation of the switching operation means.

すなわち、坩堝支持体が、坩堝の上部を吊り下げ支持自在に構成されているから、坩堝を育成装置に上方側から装填し易いものとなる。説明を加えると、例えば、支持台に載置された坩堝を横側方から加熱するヒータが平面視で環状となるように備えられている場合は、第2移動動作や第3移動動作によりヒータの上方側から坩堝を挿入するようにして坩堝を支持台に装填することとなるが、坩堝支持体にて坩堝の上部を吊り下げ支持することで、坩堝を載置台の上方側から装填するときに、坩堝支持体や移動操作手段がヒータに干渉し難く、坩堝を育成装置に装填し易いものとなる。
そして、坩堝搬送車を坩堝受取位置に走行させて、坩堝搬入箇所に位置する坩堝をフォーク装置にて掬い取り、切換操作手段にて坩堝支持体と坩堝載置体とを近接状態に切り換えて坩堝支持体にて坩堝を保持した後に、切換操作手段にて坩堝支持体と坩堝載置体とを離間状態に切り換えて坩堝支持体にて坩堝を吊り下げ支持するため、坩堝搬入箇所の坩堝を坩堝支持体にて載置支持するようにフォーク装置にて掬い取ることができるので、坩堝搬入箇所から坩堝を受け取る際や第1移動動作を実行する際に坩堝載置体にて坩堝を安定よく支持することができる。
従って、第2移動動作や第3移動動作を実行する際には坩堝支持体にて吊り下げ支持して、坩堝を育成装置に装填し易いものとしながら、坩堝搬入箇所から坩堝を受け取る際や第1移動動作を実行する際には坩堝支持体にて坩堝を載置支持して坩堝を安定よく支持することができる単結晶棒育成設備を提供することができるに至った。
That is, since the crucible support is configured to freely support the upper part of the crucible, the crucible can be easily loaded into the growth apparatus from above. For example, when the heater for heating the crucible placed on the support base from the lateral side is provided in an annular shape in plan view, the heater is moved by the second movement operation or the third movement operation. When the crucible is loaded from the upper side of the mounting table, the crucible is loaded from the upper side of the mounting table. In addition, the crucible support and the moving operation means do not easily interfere with the heater, and the crucible can be easily loaded into the growing apparatus.
Then, the crucible transporting vehicle is moved to the crucible receiving position, the crucible located at the crucible carrying position is scooped up by the fork device, and the crucible support body and the crucible mounting body are switched to the proximity state by the switching operation means. After holding the crucible with the support, the crucible support and the crucible mounting body are switched to the separated state by the switching operation means, and the crucible is suspended and supported by the crucible support. Since it can be scooped up with a fork device so that it is placed and supported by the support, the crucible is stably supported by the crucible placing body when receiving the crucible from the crucible carry-in location or when performing the first movement operation. can do.
Therefore, when the second movement operation or the third movement operation is performed, the crucible support is suspended and supported so that the crucible can be easily loaded into the growing apparatus, while the crucible is received from the crucible loading position or the second movement operation. When carrying out one moving operation, a crucible support was placed and supported on the crucible support to provide a single crystal rod growing facility capable of stably supporting the crucible.

本発明にかかる単結晶棒育成設備の第3特徴構成は、第2特徴構成において、前記フォーク装置の前記坩堝載置体が、前記坩堝を水平方向への移動を許容する状態で載置する許容状態と前記坩堝を水平方向への移動を規制する状態で載置する規制状態とに切り換え可能に構成され、前記坩堝載置体が前記載置搬送位置に位置し且つ前記許容状態であるときに、前記坩堝載置体に載置された前記坩堝の横側方から前記坩堝を押圧操作して、前記坩堝を前記坩堝支持体にて保持されるのに適した適正載置位置に移動させる押圧操作手段が設けられている点にある。   The third characteristic configuration of the single crystal rod growing facility according to the present invention is the second characteristic configuration, wherein the crucible mounting body of the fork device is allowed to place the crucible in a state allowing the movement in the horizontal direction. When the crucible placement body is located at the placement transport position and in the permissible state, the crucible placement body is configured to be switchable between a state and a restriction state in which the crucible is placed in a state of restricting movement in the horizontal direction. And pressing the crucible from the lateral side of the crucible mounted on the crucible mounting body to move the crucible to an appropriate mounting position suitable for being held by the crucible support. The operation means is provided.

すなわち、坩堝載置体が載置搬送位置に位置し且つ許容状態であるときに、坩堝載置体に載置された坩堝をその横側方から押圧操作手段にて押圧操作することにより、坩堝載置体に載置された坩堝が坩堝支持体にて保持されるのに適した適正載置位置からずれて位置していても、その坩堝を水平方向に移動させて適性載置位置に移動させることができる。従って、坩堝を水平方向に移動させて坩堝を適性載置位置に位置させた状態で、坩堝支持体にて坩堝を保持させることができるので、坩堝支持体にて坩堝を適正に保持することができる。これにより、坩堝を支持台に装填する際に坩堝を支持台に対して適正位置に装填し易いものとなる。
また、坩堝支持体を規制状態に切り換えた状態で坩堝搬入箇所に位置する坩堝をフォーク装置にて掬い取ることにより、坩堝を掬い取るときに坩堝が不意に水平方向に移動して坩堝載置体から坩堝が転落することを防止することができる。
従って、坩堝を掬い取るときの坩堝の落下を防止しながら坩堝支持体にて坩堝を適正に保持することができる単結晶棒育成設備を提供することができるに至った。
That is, when the crucible mounting body is located at the mounting transport position and is in an allowable state, the crucible mounted on the crucible mounting body is pressed by the pressing operation means from the lateral side thereof, thereby Even if the crucible placed on the mounting body is shifted from the proper mounting position suitable for being held by the crucible support, the crucible is moved in the horizontal direction and moved to the appropriate mounting position. Can be made. Therefore, since the crucible can be held by the crucible support in a state where the crucible is moved in the horizontal direction and the crucible is positioned at the proper mounting position, the crucible can be properly held by the crucible support. it can. Thereby, when the crucible is loaded on the support base, the crucible is easily loaded at an appropriate position with respect to the support base.
In addition, when the crucible support is switched to the regulated state, the crucible located at the crucible loading position is scraped by the fork device, so that when the crucible is scraped, the crucible unexpectedly moves horizontally and the crucible mounting body It is possible to prevent the crucible from falling.
Accordingly, it has been possible to provide a single crystal rod growing facility capable of properly holding the crucible with the crucible support while preventing the crucible from dropping when the crucible is scraped.

本発明にかかる単結晶棒育成設備の第4特徴構成は、第1〜第3特徴構成のいずれか1つにおいて、前記支持手段が、前記坩堝支持体と前記移動操作手段との間に設けられて前記坩堝支持体が前記移動操作手段に対して水平方向に移動することを許容する弾性部材にて構成されている点にある。   According to a fourth feature configuration of the single crystal rod growing facility according to the present invention, in any one of the first to third feature configurations, the support means is provided between the crucible support and the movement operation means. The crucible support is formed of an elastic member that allows the crucible support to move in the horizontal direction with respect to the moving operation means.

すなわち、坩堝支持体と移動操作手段との間に弾性部材を設けるだけで、第3移動動作を実行するときに坩堝支持体が移動操作手段に対して水平方向に移動することを許容することができるため、支持手段を簡素な構成とすることができる。
つまり、例えば、支持手段を坩堝搬送車や移動操作手段にて構成して、坩堝搬送車の制動を解除して坩堝搬送車を自由移動状態とすることや、移動操作手段による坩堝支持体の装填用位置での保持を解除して移動操作手段を自由操作状態とすることにより、第3移動動作を実行するときに坩堝支持体を水平方向に自由移動する状態とすることも考えられるが、この場合、坩堝搬送車の位置や坩堝支持体の位置が変わるため、制御手段は、坩堝搬送車の位置情報や坩堝支持体の位置情報を位置変更後の情報に更新する必要がある。
従って、支持手段を簡素な構成とすることができる単結晶棒育成設備を提供することができるに至った。
That is, by providing an elastic member between the crucible support and the movement operation means, the crucible support can be allowed to move in the horizontal direction with respect to the movement operation means when performing the third movement operation. Therefore, the support means can be configured simply.
That is, for example, the support means is constituted by a crucible transport vehicle or a movement operation means, and the crucible transport vehicle is released by releasing the braking, or the crucible support body is loaded by the movement operation means. It is conceivable that the crucible support can be moved freely in the horizontal direction when the third movement operation is performed by releasing the holding at the operation position and setting the moving operation means to the free operation state. In this case, since the position of the crucible transport vehicle and the position of the crucible support change, the control means needs to update the position information of the crucible transport vehicle and the position information of the crucible support to the information after the position change.
Accordingly, it has been possible to provide a single crystal rod growing facility in which the support means can have a simple configuration.

本発明にかかる単結晶棒育成設備の第5特徴構成は、第1〜第4特徴構成のいずれか1つにおいて、前記坩堝支持体が、前記坩堝を支持する支持作用部分と、前記移動操作手段にて移動される支持本体部分と、前記支持作用部分を前記支持本体部分に対して昇降移動させる昇降操作手段とを備えて構成され、前記案内位置決め手段が、前記育成装置に備えられた被係合部と前記支持本体部分に備えられて前記被係合部に上方側から係合可能な係合部とを備えて構成されている点にある。   The fifth characteristic configuration of the single crystal rod growing facility according to the present invention is any one of the first to fourth characteristic configurations, wherein the crucible support body supports the crucible, and the moving operation means. And a lifting operation means for moving the supporting action part up and down with respect to the supporting body part, and the guide positioning means is provided in the rearing apparatus. It is in the point which is provided with the engaging part and the engaging part which can be engaged with the said to-be-engaged part from the upper side, and is provided in the said support body part.

すなわち、第3移動動作を実行して昇降台を坩堝支持体にて支持された坩堝が支持台に装填される高さに下降させると、支持本体部分に備えられた係合部が育成装置に備えられた被係合部に上方側から係合し、この係合により坩堝支持体が水平方向に案内されて支持台に対する適正位置に位置決めされる。
そして、このように坩堝支持体を適正位置に位置決めした状態で、昇降操作手段にて支持作用部分を支持本体部分に対して下降移動させることにより、坩堝支持体を案内位置決め手段にて位置決めした状態では、支持本体部分が育成装置の支持台に対して水平方向に位置決めされているため、支持作用部分を水平方向への移動を極力伴わずに下降移動させることができるので、坩堝を育成装置に適正に装填し易いものとなる。
説明を加えると、例えば、支持台に載置された坩堝を横側方から加熱するヒータが平面視で環状となるように備えられている場合は、第2移動動作や第3移動動作によりヒータの上方側から坩堝を挿入するようにして坩堝を支持台に装填することとなり、この様な場合に坩堝支持体の全体を下降移動させて坩堝を上方側から挿入しようとすると、坩堝支持体がヒータに干渉し易いが、坩堝支持体の支持作用部分のみを下降移動させて坩堝を上方側から挿入することにより、坩堝支持体がヒータに干渉し難く、坩堝を育成装置に適正に装填し易いものとなる。
このように、坩堝を育成装置に適正に装填し易い単結晶棒育成設備を提供することができるに至った。
That is, when the third movement operation is performed and the lifting platform is lowered to a height at which the crucible supported by the crucible support is loaded on the support platform, the engaging portion provided in the support main body portion becomes the growth device. The engaged portion provided is engaged from above, and by this engagement, the crucible support is guided in the horizontal direction and positioned at an appropriate position with respect to the support base.
And in a state where the crucible support is positioned at an appropriate position in this way, the support operation part is moved down with respect to the support main body part by the lifting operation means, and the crucible support is positioned by the guide positioning means. Then, since the support main body part is positioned in the horizontal direction with respect to the support base of the growth apparatus, the support action part can be moved downward without moving in the horizontal direction as much as possible. It becomes easy to load properly.
For example, when the heater for heating the crucible placed on the support base from the lateral side is provided in an annular shape in plan view, the heater is moved by the second movement operation or the third movement operation. The crucible is inserted into the support base so that the crucible is inserted from above, and in this case, when the entire crucible support is moved downward and the crucible is inserted from above, the crucible support is Although it is easy to interfere with the heater, the crucible support is unlikely to interfere with the heater by moving only the support working part of the crucible support downward and inserting the crucible from above, and the crucible is easily loaded into the growth apparatus. It will be a thing.
As described above, it has been possible to provide a single crystal rod growing facility that can easily load the crucible into the growing apparatus properly.

本発明にかかる単結晶棒育成設備の第6特徴構成は、第1〜第5特徴構成のいずれか1つにおいて、前記育成装置が、直線状に複数並べて設けられ、前記坩堝搬送車が、前記複数の育成装置の並び方向に沿う直線状の走行経路に沿って移動自在に設けられている点にある。   A sixth feature configuration of the single-crystal rod growing facility according to the present invention is any one of the first to fifth feature configurations, wherein a plurality of the growing devices are arranged in a straight line, and the crucible carrier vehicle is It exists in the point provided so that movement is possible along the linear travel path | route along the row direction of a some growing apparatus.

すなわち、複数の育成装置の並び方向に沿う直線状の走行経路に沿って走行自在な坩堝搬送車が、坩堝受取位置と育成装置に対して坩堝を装填する複数の坩堝装填位置とに走行自在に構成されているため、坩堝搬送車を坩堝受取位置に移動させて搬入装置等から坩堝を受け取った後、坩堝搬送車を坩堝装填位置に移動させて育成装置に対して坩堝を装填するようにして、坩堝搬送車にて坩堝を搬送して育成装置に装填することができる。

In other words, the pressing operation means 28 is provided with four pressing bodies 28a so as to press the crucible pallet 7 mounted on the crucible mounting body 24 from four directions. When the body 28a moves close to the crucible pallet 7 and presses the crucible pallet 7, the crucible 3 is indirectly pressed. Incidentally, in order to avoid interference with the crucible pallet 7 placed on the crucible placing body 24 when the crucible placing body 24 moves, the pressing operation means 28 has a quadrangular crucible pallet 7 in plan view with the four pressing bodies 28a. These corners are configured to be pressed toward the center of the crucible pallet 7. FIG. 8 schematically shows that the crucible pallet 7 is pressed by the pressing body 28a.
By pressing the crucible 3 with the pressing operation means 28 in this way, the crucible 3 positioned in the horizontal direction is rotated from the proper placement position suitable for being held by the crucible support 26. It is possible to move the ball on the plurality of free ball bodies 24a in the horizontal direction so as to be positioned at an appropriate placement position.

坩堝装填用フォーク装置27は、坩堝支持体26を搬送用位置と走行経路Lの横幅方向両側に位置する装填用位置とに移動させるように、走行経路Lの横幅方向の両方側に出退自在に構成されている。この坩堝装填用フォーク装置27は、坩堝支持体26の搬送用位置が坩堝載置体24の載置運搬位置と上下方向に重複するように坩堝受取用フォーク装置25の上方に設けられている。
また、坩堝装填用フォーク装置27は、昇降台23に位置固定状態のフォーク基部27bに対して坩堝支持体26を吊り下げ支持するフォーク先端部27aが走行経路Lの横幅方向に沿ってフォーク基部27bの下方側でスライド移動するように構成されている。
ちなみに、坩堝受取用フォーク装置25は、坩堝載置体24を載置支持するフォーク先端部がフォーク基部の上方側でスライド移動するように構成されている。
The crucible loading fork device 27 can be moved back and forth on both sides in the lateral direction of the travel path L so as to move the crucible support 26 to the transport position and the loading positions located on both sides of the travel path L in the lateral width direction. It is configured. This crucible loading fork device 27 is provided above the crucible receiving fork device 25 so that the transport position of the crucible support 26 overlaps the mounting and transporting position of the crucible mounting body 24 in the vertical direction.
In addition, the fork device 27 for loading the crucible has a fork tip portion 27a that suspends and supports the crucible support 26 with respect to the fork base portion 27b fixed to the lifting platform 23 along the lateral width direction of the travel path L. It is comprised so that a slide movement may be carried out below.
Incidentally, the crucible receiving fork device 25 is configured such that the tip of the fork for mounting and supporting the crucible mounting body 24 slides on the upper side of the fork base.

次に、坩堝支持体26について説明を加える。
図8及び図9に示すように、前記坩堝支持体26は、前記坩堝3を吊り下げ支持する支持作用部分31と、前記坩堝装填用フォーク装置27に吊り下げ支持されてこの坩堝装填用フォーク装置27にて移動される支持本体部分32と、支持作用部分31と支持本体部分32とを連結させるとともに前記支持作用部分31を前記支持本体部分32に対して昇降移動させる昇降操作手段33とを備えて構成されている。
Next, the crucible support 26 will be described.
As shown in FIGS. 8 and 9, the crucible support 26 is supported by being suspended and supported by a supporting action portion 31 for hanging and supporting the crucible 3 and the crucible loading fork device 27. 27, and a lifting operation means 33 for connecting the supporting action part 31 and the supporting body part 32 and moving the supporting action part 31 up and down relative to the support body part 32. Configured.

支持作用部分31には、その下面に坩堝3の上端部形状に合わせた環状のシールゴム34と、このシールゴム34の内側において支持作用部分31の下方の空気をエアーホース35を通して吸引する坩堝吸着保持用の吸引装置(図示せず)とを備えて構成されている。
つまり、昇降操作手段33にて支持作用部分31を支持本体部分32(坩堝載置体24)に対して下降させて後述する接近状態することにより、シールゴム34が坩堝3の上端部に密着する状態となり、この状態において吸引装置にて支持作用部分31の下方の空気となる坩堝3内の空気を吸引することにより、支持作用部分31にて坩堝3の上端部を吸着保持することができる。また、支持作用部分31にて坩堝3の上端部を吸着保持した状態において、昇降操作手段33にて支持作用部分31を支持本体部分32(坩堝載置体24)に対して上昇させて後述する離間状態とすることにより、坩堝3を坩堝載置体24から持ち上げて、支持作用部分31にて坩堝3を吊り下げ支持することができる。
ちなみに、坩堝3の上端部を吸着保持しない状態において離間状態とすることにより、坩堝受取用フォーク装置25にて坩堝3を受け取る際に坩堝3が坩堝支持体26に接当しないように、坩堝支持体26を上方に退避させることができる。
The supporting action portion 31 has an annular seal rubber 34 matched to the shape of the upper end of the crucible 3 on the lower surface thereof, and a crucible adsorbing and holding member that sucks air below the supporting action portion 31 through the air hose 35 inside the seal rubber 34. And a suction device (not shown).
That is, the seal rubber 34 is in close contact with the upper end portion of the crucible 3 by lowering the support action portion 31 with respect to the support main body portion 32 (the crucible mounting body 24) by the lifting operation means 33 and entering an approaching state described later. In this state, the upper end portion of the crucible 3 can be adsorbed and held by the support action portion 31 by sucking the air in the crucible 3 that is the air below the support action portion 31 by the suction device. Further, in a state where the upper end portion of the crucible 3 is sucked and held by the support action portion 31, the support action portion 31 is raised with respect to the support main body portion 32 (the crucible mounting body 24) by the lifting operation means 33, which will be described later. By setting it in the separated state, the crucible 3 can be lifted from the crucible mounting body 24 and the crucible 3 can be suspended and supported by the support action portion 31.
By the way, the crucible 3 is supported so that the crucible 3 does not come into contact with the crucible support 26 when the crucible 3 is received by the crucible receiving fork device 25 by separating the upper end of the crucible 3 without sucking and holding it. The body 26 can be retracted upward.

支持本体部分32は、走行経路Lの横幅方向に沿う横軸心周りに揺動自在な揺動体36とコイルスプリング29とを介して坩堝装填用フォーク装置27のフォーク先端部27aに吊り下げ支持されている。よって、支持本体部分32は、揺動体36により走行経路Lの横幅方向に沿う軸心周りに揺動自在で、且つ、コイルスプリング29により坩堝装填用フォーク装置27に対して水平方向に移動自在で且つ坩堝装填用フォーク装置27に対する所定位置に復帰付勢される。
支持本体部分32には、引上げ装置1に備えられた被係合部としての被係合体37に上方側から係合可能な係合部としての係合ピン38が備えられている。この係合ピン38は、支持作用部分31より横外方側に位置するように支持本体部分32の周囲に下方に突出する状態で3本備えられている。また、支持本体部分32の下面における少なくとも係合ピン38の周囲の部分(被係合体37と接当する部分)が、被係合体37の上面と同様に平坦面に形成されている。ちなみに、被係合体37は、引上げ装置1における下チャンバ9内に備えられており、下方に向けて凹入する凹入部が形成されている。尚、係合ピン38は図6に示す位置に設けられており、また、被係合体37は図2及び図3に示す位置に設けられており、図8及び図9の係合ピン38や被係合体37の位置は概略的に図示している。
The support main body 32 is suspended and supported by a fork tip 27a of the crucible loading fork device 27 via a swinging body 36 and a coil spring 29 that can swing around a horizontal axis along the lateral width direction of the travel path L. ing. Therefore, the support main body portion 32 can be swung around the axis along the lateral width direction of the travel path L by the rocking body 36 and can be moved in the horizontal direction with respect to the crucible loading fork device 27 by the coil spring 29. In addition, it is biased back to a predetermined position with respect to the crucible loading fork device 27.
The support main body portion 32 is provided with an engaging pin 38 as an engaging portion that can be engaged with an engaged body 37 as an engaged portion provided in the pulling device 1 from above. Three engagement pins 38 are provided in a state of projecting downward around the support main body portion 32 so as to be located laterally outward from the support operation portion 31. Further, at least a portion around the engagement pin 38 (a portion contacting the engaged body 37) on the lower surface of the support main body portion 32 is formed on a flat surface like the upper surface of the engaged body 37. Incidentally, the to-be-engaged body 37 is provided in the lower chamber 9 in the pulling device 1, and a recessed portion that is recessed downward is formed. The engaging pin 38 is provided at the position shown in FIG. 6, and the engaged body 37 is provided at the position shown in FIGS. 2 and 3, and the engaging pin 38 shown in FIGS. The position of the engaged body 37 is schematically shown.

係合ピン38としては、直径が30mm程度の円柱状に形成されており、その先端部は、先端側ほど細い形状に形成されている。また、被係合体37には、係合ピン38を係合する凹入部の直径が30.5mm程度の係合ピン38の直径より1、2パーセント大きな円形に形成されている。
つまり、係合ピン38と被係合体37とが、下降される前記坩堝支持体26を水平方向に案内して前記支持台13に対する適正位置に位置決めする案内位置決め手段43を構成している。
The engagement pin 38 is formed in a columnar shape having a diameter of about 30 mm, and the tip portion thereof is formed so as to be thinner toward the tip side. In addition, the engaged body 37 is formed in a circular shape having a diameter that is 1 to 2 percent larger than the diameter of the engaging pin 38 with which the diameter of the recessed portion for engaging the engaging pin 38 is about 30.5 mm.
That is, the engaging pin 38 and the engaged body 37 constitute a guide positioning means 43 that guides the crucible support body 26 to be lowered in a horizontal direction and positions the crucible support body 26 at an appropriate position with respect to the support base 13.

よって、坩堝3を支持台13上に装填するべく昇降台23を下降させたときに、坩堝支持体26が支持台13に対する適正位置から水平方向にずれている場合は、係合ピン38が被係合体37に係合する際に係合ピン38の先端部に形成された傾斜にて坩堝支持体26が適正位置に案内される。そして、係合ピン38が被係合体37に係合することによって、坩堝支持体26の水平方向での位置が適正位置に位置決めされる。また、坩堝3を引上げ装置1に装填するときに坩堝装填用フォーク装置27の撓み等により坩堝支持体26が傾いていた場合でも、支持本体部分32が被係合体37に接当して揺動体36と坩堝支持体26とが横軸心周りに一体的に揺動することにより坩堝支持体26を水平な姿勢に変更することができる。   Therefore, if the crucible support 26 is displaced from the appropriate position with respect to the support base 13 when the elevating base 23 is lowered so as to load the crucible 3 onto the support base 13, the engagement pin 38 is not covered. When engaging the engagement body 37, the crucible support 26 is guided to an appropriate position by the inclination formed at the tip of the engagement pin 38. Then, when the engagement pin 38 is engaged with the engaged body 37, the horizontal position of the crucible support 26 is positioned at an appropriate position. Even when the crucible support 26 is tilted due to bending of the crucible loading fork device 27 when the crucible 3 is loaded into the pulling device 1, the support main body portion 32 contacts the engaged body 37 and the swinging body. The crucible support 26 can be changed to a horizontal posture by integrally swinging the crucible 36 and the crucible support 26 around the horizontal axis.

昇降操作手段33は、支持本体部分32に取り付けられた昇降駆動部39と支持作用部分31に取り付けられて昇降駆動部39のピニオン(図示せず)に噛合するラック40とで構成されており、昇降駆動部39のピニオンを回転させてラック40を昇降移動させることにより、支持作用部分31を係合ピン38(支持本体部分32)に対して昇降移動するように構成されている。
つまり、上述した如く、係合ピン38を被係合体37に係合させて坩堝支持体26の水平方向での位置を適正位置に位置決めした状態で、昇降操作手段33にて支持作用部分31を下降移動させることにより、坩堝3が支持台13上に装填される。
The elevating operation means 33 includes an elevating drive part 39 attached to the support main body part 32 and a rack 40 attached to the support action part 31 and meshing with a pinion (not shown) of the elevating drive part 39. By rotating the pinion of the elevating drive unit 39 and moving the rack 40 up and down, the support action portion 31 is configured to move up and down relative to the engagement pin 38 (support body portion 32).
That is, as described above, in the state where the engaging pin 38 is engaged with the engaged body 37 and the position of the crucible support 26 in the horizontal direction is positioned at an appropriate position, the support operating portion 31 is moved by the lifting operation means 33. By moving downward, the crucible 3 is loaded on the support base 13.

また、昇降操作手段33は、このように支持作用部分31を昇降移動させることにより、支持作用部分31が坩堝載置体24に対して遠近移動するように構成されている。
つまり、昇降操作手段33は、坩堝載置体24を載置搬送位置に位置させ且つ坩堝支持体26を搬送用位置に位置させた状態において、支持作用部分31を坩堝載置体24に対して下降させることにより、前記坩堝搬送位置に位置する前記坩堝載置体24に載置された前記坩堝3の上部を前記坩堝支持体26にて保持するべく前記坩堝支持体26と前記坩堝載置体24とを上下方向に接近させた接近状態に切り換えることができ、また、支持作用部分31を坩堝載置体24に対して上昇させることにより、保持した前記坩堝3を吊り下げ支持するべく前記坩堝支持体26と前記坩堝載置体24とを上下方向に離間させた離間状態に切り換えることができる。従って、昇降操作手段33は、坩堝支持体26と坩堝載置体24とを近接状態や離間状態に切り換える切換操作手段41としても機能するように構成されている。
ちなみに、坩堝支持体26には、支持作用部分31を昇降案内する昇降案内手段42が備えられている。この昇降案内手段42は、支持本体部分32に取り付けられたガイドブロックと支持作用部分31に取り付けられてガイドブロックにて昇降案内されるガイドレールとで構成されている。
Further, the raising / lowering operation means 33 is configured such that the supporting action portion 31 moves far and away with respect to the crucible mounting body 24 by moving the supporting action portion 31 up and down in this way.
That is, the raising / lowering operation means 33 moves the supporting portion 31 relative to the crucible mounting body 24 in a state where the crucible mounting body 24 is positioned at the mounting transport position and the crucible support body 26 is positioned at the transporting position. By lowering, the crucible support 26 and the crucible mounting body are held by the crucible support 26 so that the upper part of the crucible 3 placed on the crucible mounting body 24 located at the crucible transport position is held by the crucible support 26. 24 can be switched to an approaching state in which they are moved close to each other in the vertical direction, and the crucible 3 is suspended and supported by lifting the supporting portion 31 with respect to the crucible mounting body 24. The support body 26 and the crucible mounting body 24 can be switched to a separated state in which the support body 26 and the crucible mounting body 24 are separated in the vertical direction. Therefore, the raising / lowering operation means 33 is configured to function also as a switching operation means 41 for switching the crucible support 26 and the crucible mounting body 24 between a proximity state and a separation state.
Incidentally, the crucible support body 26 is provided with an elevating guide means 42 for elevating and guiding the supporting action portion 31. The elevating and lowering guide means 42 includes a guide block attached to the support main body portion 32 and a guide rail attached to the support action portion 31 and guided by the guide block.

次に、坩堝搬送用制御装置h1について説明を加える。
図13に示すように、坩堝搬送用制御装置h1は、上位のコントローラHからの指令に基づいて、坩堝用スタッカークレーン20を坩堝受取位置に走行させて、坩堝搬入箇所に位置する坩堝3を掬い取り、搬入装置5の搬入用状態の坩堝3を坩堝用スタッカークレーン20にて受け取る坩堝受取制御を実行し、次に、坩堝用スタッカークレーンを坩堝装填位置に走行させて、坩堝3を引上げ装置1の支持台13に装填して、搬入装置5から受け取った搬入用状態の坩堝3を坩堝用スタッカークレーン20にて引上げ装置1に装填する坩堝装填制御を実行して、搬入装置5にて搬入された坩堝3を坩堝用スタッカークレーン20にて引上げ装置1に装着するべく、坩堝用スタッカークレーン20の作動、具体的には、坩堝用スタッカークレーン20の走行作動、昇降台23の昇降作動、坩堝載置体24の作動、坩堝受取用フォーク装置25の移動作動、坩堝支持体26の作動、坩堝装填用フォーク装置27の移動作動、及び、押圧操作手段28の押圧作動を制御するように構成されている。
Next, the crucible conveyance control device h1 will be described.
As shown in FIG. 13, the crucible transport control device h1 drives the crucible stacker crane 20 to the crucible receiving position based on a command from the host controller H, and scoops the crucible 3 located at the crucible loading position. Then, crucible receiving control is performed in which the crucible 3 in the loading state of the loading device 5 is received by the crucible stacker crane 20, and then the crucible stacker crane is moved to the crucible loading position, and the crucible 3 is pulled up. The crucible 3 is loaded into the support stand 13, and the crucible 3 in the loading state received from the loading device 5 is loaded into the pulling device 1 with the crucible stacker crane 20. In order to mount the crucible 3 on the pulling device 1 with the crucible stacker crane 20, the operation of the crucible stacker crane 20, specifically, the crucible stacker crane 0 travel operation, lifting platform 23 lifting operation, crucible mounting body 24 operation, crucible receiving fork device 25 moving operation, crucible support body 26 operation, crucible loading fork device 27 moving operation, and pressing It is comprised so that the press action of the operation means 28 may be controlled.

坩堝装填制御について説明を加えると、坩堝装填制御では、図2及び図6に示すように、前記坩堝用スタッカークレーン20を前記坩堝装填位置に走行させ且つ前記昇降台23を前記坩堝支持体26にて支持される前記坩堝3が前記支持台13より上方に位置する高さに昇降させる第1移動動作、図9(a)に示すように、この第1移動動作完了後に前記坩堝装填用フォーク装置27にて前記坩堝支持体26を前記搬送用位置から前記装填用位置に移動させる第2移動動作、及び、図9(b)に示すように、この第2移動動作完了後に前記昇降台23を前記坩堝3が前記支持台13に装填される高さに下降させる第3移動動作により、前記坩堝3を前記支持台13に載置させるべく、前記坩堝用スタッカークレーン20の走行作動、前記昇降台23の昇降作動、及び、前記坩堝装填用フォーク装置27の移動作動を制御する。   The crucible loading control will be described below. In the crucible loading control, as shown in FIGS. 2 and 6, the crucible stacker crane 20 is moved to the crucible loading position and the lifting platform 23 is moved to the crucible support 26. A first moving operation in which the crucible 3 to be supported is moved up and down to a height located above the support base 13, as shown in FIG. 9A, the crucible loading fork device after the completion of the first moving operation. 27, the second movement operation for moving the crucible support 26 from the transfer position to the loading position, and as shown in FIG. 9B, the lift table 23 is moved after the second movement operation is completed. In order to place the crucible 3 on the support table 13 by a third movement operation for lowering the crucible 3 to a height at which the support table 13 is loaded, the crucible stacker crane 20 is moved and moved up and down. Lifting operation of 23, and controls the movement operation of the crucible loading fork device 27.

そして、第1移動動作中において、まず、載置搬送位置に位置する坩堝載置体24を規制状態から許容状態に切り換えた後に、押圧操作手段28を押圧作動させて、坩堝載置体24に載置された坩堝3を適正載置位置に移動させるように、坩堝載置体24の作動、及び、押圧操作手段28の作動を制御する。
次に、前記坩堝支持体26と前記坩堝載置体24とを前記近接状態に切り換えて前記坩堝支持体26にて前記坩堝3を吸着保持した後に、前記坩堝支持体26と前記坩堝載置体24とを離間状態に切り換えて前記坩堝支持体26にて前記坩堝3を吊り下げ支持するように、前記坩堝支持体26の作動、前記坩堝装填用フォーク装置27の出退作動、及び、前記切換操作手段41の切換作動を制御する。
ちなみに、第1移動動作中とは、坩堝受取制御が終了した後で且つ坩堝装填制御の第2移動作動の開始前であればよく、坩堝3を載置した坩堝載置体24を掬い用位置から載置搬送位置に移動した後で且つ坩堝3を吊り下げ支持した坩堝支持体26を搬送用位置から装填用位置に移動する前であればよい。尚、坩堝受取制御を実行中の坩堝載置体24は規制状態に切り換えられている。
Then, during the first moving operation, first, after switching the crucible mounting body 24 located at the mounting and conveying position from the restricted state to the allowable state, the pressing operation means 28 is pressed to operate the crucible mounting body 24. The operation of the crucible mounting body 24 and the operation of the pressing operation means 28 are controlled so as to move the mounted crucible 3 to an appropriate mounting position.
Next, after the crucible support 26 and the crucible mounting body 24 are switched to the close state and the crucible 3 is adsorbed and held by the crucible support 26, the crucible support 26 and the crucible mounting body are used. 24, the crucible support 26 is suspended and supported by the crucible support 26, the crucible support 26 is operated, the crucible loading fork device 27 is retracted, and the switching is performed. The switching operation of the operating means 41 is controlled.
Incidentally, the first movement operation may be performed after the crucible receiving control is finished and before the start of the second movement operation of the crucible loading control, and the crucible placing body 24 on which the crucible 3 is placed is placed in the scooping position. What is necessary is just to move the crucible support 26 that supports the suspension of the crucible 3 from the transfer position to the loading position after moving from the transfer position to the mounting transfer position. In addition, the crucible mounting body 24 that is executing the crucible receiving control is switched to the restricted state.

第3移動動作により前記昇降台23を前記坩堝3が前記支持台13に装填される高さに下降させると係合ピン38が被係合体37に係合され、この係合ピン38が被係合体37に係合することにより、坩堝支持体26を水平方向に案内して支持台13に対する適正位置に位置決めされる。また、第3移動動作を実行するときは、坩堝支持体26はコイルスプリング29にて水平方向に自由移動する状態に支持されている。
そして、上述の如く昇降台23の下降により係合ピン38が被係合体37に係合されている状態で昇降操作手段33にて支持作用部分31を下降移動させることにより、坩堝3が支持台13上に装填される。
When the elevating platform 23 is lowered to a height at which the crucible 3 is loaded on the support platform 13 by the third moving operation, the engaging pin 38 is engaged with the engaged body 37, and the engaging pin 38 is engaged. By engaging with the united body 37, the crucible support 26 is guided in the horizontal direction and positioned at an appropriate position with respect to the support base 13. When performing the third movement operation, the crucible support 26 is supported by the coil spring 29 so as to freely move in the horizontal direction.
Then, as described above, the crucible 3 is moved to the support table by moving the support operation portion 31 downward by the lifting operation means 33 in a state where the engagement pin 38 is engaged with the engaged body 37 by the lowering of the lift table 23. 13 is loaded.
