Description
本発明は、造形装置において造形物を形成しなかった粉末材料を除去する技術に関する。
The present invention relates to a technique for removing a powder material that has not formed a modeled object in a modeling apparatus.
上記技術分野において、特許文献1には、粉末材料を結合させて3次元造形物を積層造形した後に、3次元造形物の周囲から未結合の粉末材料を除去する技術が開示されている。
In the above technical field, Patent Document 1 discloses a technique for removing unbound powder material from the periphery of a three-dimensional structure after the three-dimensional structure is layered by combining powder materials.
しかしながら、上記文献に記載の技術は、送風と吸引とにより、自動的に3次元造形物の周囲から未結合の粉末材料を除去する技術である。このような技術を実現するには大がかりな構成の追加や複雑な制御が必要となり、一般的に、3次元造形物の周囲から造形物を形成しなかった粉末材料を除去する作業の一部は人力に頼っている。すなわち、積層造形された3次元造形物を取りだす際に造形タンク内の造形物を形成しなかった粉末材料を除去する必要があり、造形タンクの周囲に設けられた貯蔵部に造形物を形成しなかった粉末材料を落として、造形タンク外に排出することで除去する。
However, the technique described in the above document is a technique for automatically removing unbound powder material from the periphery of the three-dimensional structure by blowing and suction. In order to realize such a technology, it is necessary to add a large-scale configuration and complicated control, and in general, part of the work of removing the powder material that did not form the modeled object from the periphery of the three-dimensional modeled object is Rely on human power. That is, it is necessary to remove the powder material that did not form the modeled object in the modeling tank when taking out the three-dimensional modeled object, and the modeled object is formed in the storage unit provided around the modeled tank. The powder material that did not exist is dropped and removed by discharging it out of the modeling tank.
その場合に、粉末除去の作業者が、各貯蔵部の近傍に移動して造形物を形成しなかった粉末材料をそれぞれ排出して除去する必要がある。しかし、作業者は、各貯蔵部のそばに居ながら排出元となる貯蔵部を切り替えることが出来ず、作業効率が悪くなる。また、造形物を形成しなかった粉末材料を吸引して除去する場合、造形物を形成しなかった粉末材料が無い貯蔵部を吸引すると空気を吸い込んで他の貯蔵部からの吸引力が落ちる。
In that case, it is necessary for the powder removing operator to move to the vicinity of each storage unit and discharge and remove the powder material that did not form a model. However, the worker cannot switch the storage unit as the discharge source while being near each storage unit, and the work efficiency is deteriorated. When the powder material that did not form the modeled object is removed by suction, if the storage part without the powder material that did not form the modeled object is suctioned, air is sucked in and the suction force from the other storage parts decreases.
本発明の目的は、上述の課題を解決する技術を提供することにある。

FIG. 2 is a diagram showing a configuration of the
図2において、粉末除去装置200の状態210は、造形装置において3次元造形物211の積層造形処理が完了した状態を示している。3次元造形物211は周囲を造形物を形成しなかった材料212および213により囲まれている。3次元造形物211を積層造形する造形タンク231の両側には、造形物を形成しなかった材料212および213を落として集めるための貯蔵部222、223が備えられている。そして、貯蔵部222、223に集められた粉末材料は、圧空制御型ボールバルブ203と204とでバルブの開閉を制御されて、吸引装置208の吸引力により片方ずつ吸引される。なお、紙面前後にも3次元造形物211の間や内部にも造形物を形成しなかった材料があるが、図2では簡略化されている。
2, a state 210 of the powder removing apparatus 200 indicates a state in which the layered modeling process of the three-dimensional modeled object 211 is completed in the modeling apparatus. The three-dimensional structure 211 is surrounded by materials 212 and 213 that did not form a structure. On both sides of the modeling tank 231 for layered modeling of the three-dimensional model 211, storage units 222 and 223 for dropping and collecting the materials 212 and 213 that did not form the model are provided. The powder materials collected in the storage units 222 and 223 are sucked one by one by the suction force of the suction device 208 while the opening and closing of the valves are controlled by the pneumatic control type ball valves 203 and 204. In addition, although there is a material in which a model is not formed between the three-dimensional model 211 or in the interior of the paper before and after the page, it is simplified in FIG.
粉末除去装置200の状態220および230は、粉末除去の作業者が貯蔵部222側の作業者206のみである場合を例に示す。しかし、貯蔵部222側の作業者206と、貯蔵部223側の作業者207との2人であってもよい。
The states 220 and 230 of the powder removing apparatus 200 show an example in which the powder removing worker is only the worker 206 on the storage unit 222 side. However, there may be two workers, the worker 206 on the storage unit 222 side and the worker 207 on the storage unit 223 side.
粉末除去装置200の状態220は、3次元造形物211の周囲にある造形物を形成しなかった粉末材料212および213が落とされて、貯蔵部222、223に集められた状態を示している。そして、状態220では、それぞれの貯蔵部222、223に手元(近傍)に配置された4ポート手動切替バルブ201および202によりコンプレッサ205の圧空が制御されて、圧空制御型ボールバルブ203および204のパイロット入力ポートに入力される。そのため、圧空制御型ボールバルブ203が開の状態、圧空制御型ボールバルブ204が閉の状態になっている。この結果、貯蔵部222内の粉末材料212が吸引される。一方、貯蔵部223内の粉末材料は圧空制御型ボールバルブ204により吸引を止められている。
The state 220 of the powder removing apparatus 200 shows a state in which the powder materials 212 and 213 that did not form the model around the three-dimensional model 211 are dropped and collected in the storage units 222 and 223. In the state 220, the compressed air of the compressor 205 is controlled by the four-port manual switching valves 201 and 202 disposed in the vicinity (in the vicinity) of the respective storage units 222 and 223, and the pilots of the pneumatic control type ball valves 203 and 204 are controlled. Input to the input port. Therefore, the pneumatic control ball valve 203 is in an open state, and the pneumatic control ball valve 204 is in a closed state. As a result, the powder material 212 in the storage unit 222 is sucked. On the other hand, the suction of the powder material in the storage unit 223 is stopped by the pneumatic control type ball valve 204.
粉末除去装置200の状態230は、貯蔵部222側の作業者206が4ポート手動切替バルブ201を切り替えることにより、圧空制御型ボールバルブ203および204のパイロット入力ポートの入力が変化する。そのため、圧空制御型ボールバルブ203が閉の状態、圧空制御型ボールバルブ204が開の状態になっている。この結果、貯蔵部223内の粉末材料213が吸引される。なお、状態220と状態230とは、逆であってもよい。
In the state 230 of the powder removing apparatus 200, the operator 206 on the storage unit 222 side switches the 4-port manual switching valve 201, whereby the inputs of the pilot input ports of the pneumatic control type ball valves 203 and 204 change. Therefore, the pneumatic control type ball valve 203 is in a closed state, and the pneumatic control type ball valve 204 is in an open state. As a result, the powder material 213 in the storage unit 223 is sucked. Note that the state 220 and the state 230 may be reversed.
粉末除去装置200の状態240および250は、粉末除去の作業者が貯蔵部223側の作業者207のみである場合を例に示す。しかし、貯蔵部222側の作業者206と、貯蔵部223側の作業者207との2人であってもよい。
The states 240 and 250 of the powder removing apparatus 200 show an example where the powder removing worker is only the worker 207 on the storage unit 223 side. However, there may be two workers, the worker 206 on the storage unit 222 side and the worker 207 on the storage unit 223 side.
粉末除去装置200の状態240では、状態220と同様に、それぞれの貯蔵部222、223に手元(近傍)に配置された4ポート手動切替バルブ201および202によりコンプレッサ205の圧空が制御されて、圧空制御型ボールバルブ203および204のパイロット入力ポートに入力される。そのため、圧空制御型ボールバルブ203が開の状態、圧空制御型ボールバルブ204が閉の状態になっている。この結果、貯蔵部222内の粉末材料212が吸引される。一方、貯蔵部223内の粉末材料は圧空制御型ボールバルブ204により吸引を止められている。
In the state 240 of the powder removing apparatus 200, as in the state 220, the compressed air of the compressor 205 is controlled by the 4-port manual switching valves 201 and 202 arranged in the vicinity (in the vicinity) of the respective storage units 222 and 223. Input to pilot input ports of control type ball valves 203 and 204. Therefore, the pneumatic control ball valve 203 is in an open state, and the pneumatic control ball valve 204 is in a closed state. As a result, the powder material 212 in the storage unit 222 is sucked. On the other hand, the suction of the powder material in the storage unit 223 is stopped by the pneumatic control type ball valve 204.
粉末除去装置200の状態250は、貯蔵部223側の作業者207が4ポート手動切替バルブ201を切り替えることにより、圧空制御型ボールバルブ203および204のパイロット入力ポートの入力が変化する。そのため、圧空制御型ボールバルブ203が閉の状態、圧空制御型ボールバルブ204が開の状態になっている。この結果、貯蔵部223内の粉末材料213が吸引される。なお、状態240と状態250とは、逆であってもよい。
In the state 250 of the powder removing apparatus 200, the operator 207 on the storage unit 223 side switches the 4-port manual switching valve 201, whereby the inputs of the pilot input ports of the pneumatic control ball valves 203 and 204 change. Therefore, the pneumatic control type ball valve 203 is in a closed state, and the pneumatic control type ball valve 204 is in an open state. As a result, the powder material 213 in the storage unit 223 is sucked. Note that the state 240 and the state 250 may be reversed.
