Description

本発明は、硬化性材料に選択的に光線を照射して三次元形状物を造形する光造形装置に関する。   The present invention relates to an optical modeling apparatus that forms a three-dimensional shape by selectively irradiating a curable material with light rays.

硬化性材料に光線を照射してその一部を硬化させ、三次元形状物を造形する光造形装置が実用化されている。この光造形装置は、ＣＡＤシステムで設計した機械部品等を容易に実体化して、設計の確認と直接的な評価とを行うことができる（例えば、特許文献１参照）。   An optical modeling apparatus that forms a three-dimensional shape by irradiating light to a curable material and partially curing the curable material has been put into practical use. This stereolithography apparatus can easily materialize mechanical parts and the like designed by a CAD system, and can perform design confirmation and direct evaluation (for example, see Patent Document 1).

光造形装置は、硬化性材料として液状の光硬化性樹脂で満たされた液槽中に昇降可能な昇降テーブルを備えている。液槽の上部が開口しており、上部から光線が照射される。三次元形状物を造形する際に、まず、光造形装置は、昇降テーブルを液状の光硬化性樹脂の液面から最下層の厚さ分だけ下降した高さに位置させる。光造形装置は、この状態でスキャナによって光線を必要な範囲内に走査して、最下層を光硬化させる。次に、光造形装置は、昇降テーブルを最下層から二番目の層の厚さ分だけ下降させ、同様にして二番目の層を光硬化させる。以降、光造形装置は、同様にして、下から順に一層ずつ光硬化させることによって製品が造形される。   The optical modeling apparatus includes an elevating table that can be moved up and down in a liquid tank filled with a liquid photocurable resin as a curable material. The upper part of the liquid tank is open, and light is irradiated from the upper part. When modeling a three-dimensional shaped object, first, the optical modeling apparatus positions the lifting table at a height lowered from the liquid surface of the liquid photocurable resin by the thickness of the lowermost layer. In this state, the optical modeling apparatus scans the light beam within a necessary range by the scanner, and photocures the lowermost layer. Next, the optical modeling apparatus lowers the lifting table by the thickness of the second layer from the lowermost layer, and similarly photocures the second layer. Thereafter, the optical modeling apparatus similarly models the product by photocuring one layer at a time from the bottom.

光造形装置の液槽は、光造形装置の枠体（フレーム）に固定されている。このため、光造形装置は、光硬化性樹脂を交換する際には、液槽の下部に台車を挿入して、台車が液槽を持ち上げることで液槽を枠体から取り外して、台車を光造形装置から引き出すことで、液槽ごと交換する。   The liquid tank of the optical modeling apparatus is fixed to the frame (frame) of the optical modeling apparatus. For this reason, when replacing the photo-curing resin, the stereolithography apparatus inserts a carriage into the lower part of the liquid tank, and the carriage lifts the liquid tank so that the liquid tank is removed from the frame, and the carriage is lightened. By pulling out from the modeling device, the entire liquid tank is replaced.

ところで、光造形装置の液槽を交換するために台車を挿入して、液槽を持ち上げることが面倒である。なお、上記課題は、光硬化性樹脂を硬化性材料として使用する光造形装置に限らず、液槽に代えてタンクに収容された金属粉末等を硬化性材料として使用する光造形装置においても同様に存在する。このため、タンクの交換作業が容易である光造形装置が求められている。   By the way, it is troublesome to insert the carriage and lift the liquid tank in order to replace the liquid tank of the optical modeling apparatus. The above problem is not limited to an optical modeling apparatus that uses a photocurable resin as a curable material, but also applies to an optical modeling apparatus that uses a metal powder or the like contained in a tank as a curable material instead of a liquid tank. Exists. For this reason, there is a need for an optical modeling apparatus that facilitates tank replacement.

本発明は、こうした実情に鑑みてなされたものであり、その目的は、タンクの交換作業が容易である光造形装置を提供することにある。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide an optical modeling apparatus in which a tank replacement operation is easy.

以下、上記目的を達成するための手段及びその作用効果について説明する。
上記課題を解決する光造形装置は、筐体内に設置されたタンク内の硬化性材料に選択的に光線を照射して前記硬化性材料を硬化させることによって三次元形状物を造形する光造形装置であって、前記タンクには、走行可能な車輪が設けられ、前記タンクを前記筐体の枠体に位置決めする位置決め部材を備え、前記位置決め部材は、前記タンクを前記枠体に設置した状態で前記タンクの出し入れ方向に沿った側面に沿って延出する誘導部材と、前
記誘導部材に取り付けられて、前記タンクと前記枠体とを固定する固定部材と、であることをその要旨としている。 Hereinafter, means for achieving the above-described object and its operation and effects will be described.
An optical modeling apparatus that solves the above-described problem is an optical modeling apparatus that models a three-dimensional object by selectively irradiating light to a curable material in a tank installed in a casing to cure the curable material. The tank is provided with a wheel capable of traveling , and includes a positioning member that positions the tank on the frame of the housing, and the positioning member is installed in a state where the tank is installed on the frame. A guide member extending along a side surface along the direction of taking in and out of the tank;
The gist of the invention is a fixing member that is attached to the guide member and fixes the tank and the frame .

同構成によれば、タンクに車輪を設けたので、タンクをそのまま光造形装置から取り出すことができ、タンクの交換作業が容易である。そして、タンクは位置決め部材によって筐体の枠体に位置決めされるので、車輪によって動いて位置が変わることを抑制できる。また、タンクを枠体に設置した状態でタンクの出し入れ方向に沿った側面に沿って延出する誘導部材を位置決め部材として備えた。このため、タンクを出し入れする際にタンクの側面を誘導して位置決めを行うことができる。また、タンクと枠体とを固定する固定部材を位置決め部材として備えた。このため、タンクは枠体に固定部材によって固定されることで、動いて位置が変わることを抑制できる。 According to this configuration, since the wheels are provided in the tank, the tank can be taken out of the optical modeling apparatus as it is, and the tank replacement operation is easy. And since a tank is positioned by the frame of a housing | casing by a positioning member, it can suppress that a position changes by moving with a wheel. Moreover, the guide member extended along the side surface along the in-and-out direction of the tank in the state which installed the tank in the frame was provided as a positioning member. For this reason, when the tank is taken in and out, the side surface of the tank can be guided and positioned. Moreover, the fixing member which fixes a tank and a frame was provided as a positioning member.

上記光造形装置について、前記位置決め部材は、前記タンクに設けられ、前記枠体の下方に挿入される挿入部材であることが好ましい。
同構成によれば、枠体の下方に挿入される挿入部材を位置決め部材としてタンクに備えた。このため、タンクが鉛直上向きに変位しようとすると、挿入部材が枠体の下部に当接して、タンクの鉛直上向きの変位を抑制できる。ここで、タンクの鉛直上向きの変位は、タンクの出し入れ時や地震時における動きである。 About the said optical modeling apparatus, it is preferable that the said positioning member is an insertion member provided in the said tank and inserted under the said frame.
According to this configuration, the tank includes the insertion member that is inserted below the frame as a positioning member. For this reason, when the tank is to be displaced vertically upward, the insertion member comes into contact with the lower portion of the frame body, and the vertically upward displacement of the tank can be suppressed. Here, the vertical upward displacement of the tank is a movement when the tank is taken in and out or during an earthquake.

上記光造形装置について、前記位置決め部材は、前記タンクと前記枠体とを係止する係止部材であることが好ましい。
同構成によれば、タンクと枠体とを係止する係止部材を位置決め部材として備えた。このため、タンクを光造形装置の筐体に入れると、タンクが枠体と係止部材によって係止することで、動いて位置が変わることを抑制できる。 About the said optical modeling apparatus, it is preferable that the said positioning member is a latching member which latches the said tank and the said frame.
According to this configuration, the locking member that locks the tank and the frame is provided as the positioning member. For this reason, when a tank is put in the housing | casing of an optical modeling apparatus, it can suppress that a tank changes with a frame and a locking member, and moves and a position changes.

本発明によれば、液槽の交換作業が容易である。   According to the present invention, it is easy to replace the liquid tank.

図３に示されるように、位置決め部材４０は、枠体２０を構成する下部の下枠２１に設けられる誘導部材４１である。誘導部材４１は、液槽５の出し入れ方向に沿った側面に沿って延出する第１板材４２と、第１板材４２の液槽５と接触する側の端部に設けられる第２板材４３とを備える。第１板材４２は、水平方向に延出する。第２板材４３は、鉛直方向に延出する。第１板材４２と第２板材４３とは、Ｌ字状の取付部材４４によって取り付けられている。液槽５の後側車輪取付部３１の誘導部材４１と対向する部分には、板状の接触部材４５が設けられている。よって、液槽５を枠体２０に対して出し入れする際は、誘導部材４１によって液槽５が誘導されて位置決めされる。   As shown in FIG. 3, the positioning member 40 is a guide member 41 provided on the lower frame 21 of the lower part constituting the frame body 20. The guide member 41 includes a first plate member 42 extending along a side surface along the direction of taking in and out of the liquid tank 5, and a second plate member 43 provided at an end of the first plate member 42 on the side in contact with the liquid tank 5. Is provided. The first plate member 42 extends in the horizontal direction. The second plate member 43 extends in the vertical direction. The first plate member 42 and the second plate member 43 are attached by an L-shaped attachment member 44. A plate-like contact member 45 is provided in a portion of the rear wheel mounting portion 31 of the liquid tank 5 that faces the guide member 41. Therefore, when the liquid tank 5 is taken in and out of the frame body 20, the liquid tank 5 is guided and positioned by the guide member 41.

また、図３及び図４に示されるように、位置決め部材４０は、液槽５と枠体２０とを固定する固定部材４６である。固定部材４６は、ボルト４７とナット４８とによって固定する。誘導部材４１の第１板材４２には、ボルト４７の螺子部を挿通する貫通孔４２ａが形成されている。液槽５の後側車輪取付部３１には、ボルト取付部材４９が設けられている。ボルト取付部材４９には、ボルト４７を挿通する貫通孔４９ａが形成されている。誘導部材４１の貫通孔４２ａと液槽５の貫通孔４９ａとの位置を一致させ、ボルト４７を挿通してナット４８によって締結することで枠体２０と液槽５とを固定する。よって、液槽５を枠体２０に挿入した後、固定部材４６によって液槽５が枠体２０に固定されて位置決めされる。   As shown in FIGS. 3 and 4, the positioning member 40 is a fixing member 46 that fixes the liquid tank 5 and the frame body 20. The fixing member 46 is fixed by a bolt 47 and a nut 48. The first plate member 42 of the guide member 41 is formed with a through hole 42 a through which the screw portion of the bolt 47 is inserted. A bolt mounting member 49 is provided on the rear wheel mounting portion 31 of the liquid tank 5. The bolt mounting member 49 is formed with a through hole 49 a through which the bolt 47 is inserted. The positions of the through hole 42 a of the guide member 41 and the through hole 49 a of the liquid tank 5 are matched, and the bolt body 47 is inserted and fastened by the nut 48 to fix the frame body 20 and the liquid tank 5. Therefore, after the liquid tank 5 is inserted into the frame body 20, the liquid tank 5 is fixed to the frame body 20 by the fixing member 46 and positioned.

また、図５及び図６に示されるように、位置決め部材４０は、液槽５に設けられ、下枠２１の下方に挿入される挿入部材５０である。挿入部材５０は、液槽５に設けられた凸部である。枠体２０には、抑え部材５１の上方に延出して挿入部材５０の跳ね上げを抑制する。よって、液槽５を枠体２０に挿入した後、挿入部材５０によって液槽５が枠体２０に対する上向きの動きを抑制されて位置決めされる。   As shown in FIGS. 5 and 6, the positioning member 40 is an insertion member 50 provided in the liquid tank 5 and inserted below the lower frame 21. The insertion member 50 is a convex portion provided in the liquid tank 5. The frame 20 extends above the restraining member 51 to restrain the insertion member 50 from jumping up. Therefore, after the liquid tank 5 is inserted into the frame body 20, the liquid tank 5 is positioned by the insertion member 50 while suppressing upward movement with respect to the frame body 20.

また、位置決め部材４０は、液槽５と枠体２０の下枠２１とを係止する係止部材５２である。係止部材５２は、液槽５に設けられた凸部５３の固定ピン５６と、下枠２１に設けられた凹部５４とを備える。凸部５３と凹部５４とは、板材によって形成されている。固定ピン５６は、円柱状であって、凸部５３に形成された貫通孔に挿入されている。凹部５４は、支持部材５５に形成されている。液槽５を枠体２０内に挿入した際に、凸部５３の固定ピン５６と凹部５４とが係合する。固定ピン５６が位置決めピンとして作用する。よって、液槽５を枠体２０に挿入した際に、係止部材５２によって液槽５が枠体２０に係合されて位置決めされる。   The positioning member 40 is a locking member 52 that locks the liquid tank 5 and the lower frame 21 of the frame body 20. The locking member 52 includes a fixing pin 56 of the convex portion 53 provided in the liquid tank 5 and a concave portion 54 provided in the lower frame 21. The convex portion 53 and the concave portion 54 are formed of a plate material. The fixing pin 56 has a columnar shape and is inserted into a through hole formed in the convex portion 53. The recess 54 is formed in the support member 55. When the liquid tank 5 is inserted into the frame body 20, the fixing pin 56 of the convex portion 53 and the concave portion 54 are engaged. The fixing pin 56 functions as a positioning pin. Therefore, when the liquid tank 5 is inserted into the frame body 20, the liquid tank 5 is engaged with the frame body 20 and positioned by the locking member 52.

以上、説明した実施形態によれば、以下の効果を奏することができる。
（１）液槽５に車輪３０を設けたので、液槽５をそのまま光造形装置から取り出すことができ、液槽５の交換作業が容易である。そして、液槽５は位置決め部材４０によって筐体１０の枠体２０に位置決めされるので、車輪３０によって動いて位置が変わることを抑制できる。 As described above, according to the embodiment described above, the following effects can be obtained.
(1) Since the wheel 30 is provided in the liquid tank 5, the liquid tank 5 can be taken out of the optical modeling apparatus as it is, and the replacement work of the liquid tank 5 is easy. Since the liquid tank 5 is positioned on the frame body 20 of the housing 10 by the positioning member 40, it can be suppressed that the position of the liquid tank 5 is moved by the wheels 30.

（２）液槽５を枠体２０に設置した状態で液槽５の出し入れ方向に沿った側面に沿って延出する誘導部材４１を位置決め部材４０として備えた。このため、液槽５を出し入れする際に液槽５の側面を誘導して位置決めを行うことができる。   (2) The guiding member 41 extending along the side surface along the direction of taking in and out of the liquid tank 5 in a state where the liquid tank 5 is installed in the frame body 20 is provided as the positioning member 40. For this reason, when the liquid tank 5 is taken in and out, the side surface of the liquid tank 5 can be guided and positioned.

（３）液槽５と枠体２０とを固定する固定部材４６を位置決め部材４０として備えた。このため、液槽５は枠体２０に固定部材４６によって固定されることで、動いて位置が変わることを抑制できる。   (3) The fixing member 46 that fixes the liquid tank 5 and the frame body 20 is provided as the positioning member 40. For this reason, the liquid tank 5 can be prevented from moving and changing its position by being fixed to the frame body 20 by the fixing member 46.

（４）枠体２０の下方に挿入される挿入部材５０を位置決め部材４０として液槽５に備えた。このため、液槽５が鉛直上向きに変位しようとすると、挿入部材５０が枠体２０の下部に当接して、液槽５の鉛直上向きの変位を抑制できる。ここで、液槽５の鉛直上向きの変位は、液槽５の出し入れ時や地震時における動きである。   (4) The liquid tank 5 was provided with the insertion member 50 inserted below the frame body 20 as the positioning member 40. For this reason, when the liquid tank 5 tries to be displaced vertically upward, the insertion member 50 comes into contact with the lower portion of the frame body 20 and the vertical upward displacement of the liquid tank 5 can be suppressed. Here, the vertically upward displacement of the liquid tank 5 is a movement when the liquid tank 5 is taken in and out or during an earthquake.

（５）液槽５と枠体２０とを係止する係止部材５２を位置決め部材４０として備えた。このため、液槽５を光造形装置の筐体１０に入れると、液槽５が枠体２０と係止部材５２によって係止することで、動いて位置が変わることを抑制できる。   (5) The locking member 52 that locks the liquid tank 5 and the frame 20 is provided as the positioning member 40. For this reason, when the liquid tank 5 is put in the housing 10 of the optical modeling apparatus, the liquid tank 5 is locked by the frame body 20 and the locking member 52, so that it is possible to suppress movement and change of position.

なお、上記実施形態は、これを適宜変更した以下の形態にて実施することができる。
・上記構成において、他の部材で液槽５と枠体２０とを位置決めできれば、係止部材５２を省略した構成を採用してもよい。 In addition, the said embodiment can be implemented with the following forms which changed this suitably.
In the above configuration, a configuration in which the locking member 52 is omitted may be adopted as long as the liquid tank 5 and the frame body 20 can be positioned by other members.

・上記構成において、液槽５の鉛直上向きの変位を抑制する必要がなければ、挿入部材５０を省略した構成を採用してもよい。 In the above configuration, if it is not necessary to suppress the upward upward displacement of the liquid tank 5, a configuration in which the insertion member 50 is omitted may be employed .

・上記実施形態では、硬化性材料として光硬化性樹脂を使用する光造形装置に採用したが、硬化性材料として金属粉末等を使用する光造形装置に採用してもよい。この場合、液槽５に代えてタンクを採用する。 -In the said embodiment, although employ | adopted for the optical modeling apparatus which uses photocurable resin as a curable material, you may employ | adopt for the optical modeling apparatus which uses a metal powder etc. as a curable material. In this case, a tank is employed instead of the liquid tank 5.
