Description

運動案内装置Exercise guidance device
　本発明は、軌道レールと移動ブロックとの隙間に外部から微細な異物が進入するのを防止するための防塵部材を備えた運動案内装置に関する。 The present invention relates to a motion guide apparatus provided with a dustproof member for preventing fine foreign matter from entering the gap between a track rail and a moving block from the outside.
　移動ブロック及び軌道レールを備えた運動案内装置では、前記移動ブロックが荷重を負荷しながら軌道レールに沿って自在に運動可能である。この種の運動案内装置は、例えば、各種工作機械や産業機械におけるＸ軸、Ｙ軸、Ｚ軸等の直線案内部に使用されている。使用される機械の用途に応じて運動案内装置の使用環境は様々である。例えば、金属加工用の工作機械においては水溶性クーラント液が軌道レールに対して降りかかり、また木材加工用の工作機械においては微細粉が軌道レールに対して付着する。このような過酷環境においても軌道レールに対する移動ブロックの円滑な運動を確保するために、これら軌道レールに付着した異物が移動ブロックの内部に侵入するのを防止する必要があり、従来から軌道レールと移動ブロックとの隙間を密封する防塵部材が提供されている。 In the motion guide device provided with the moving block and the track rail, the moving block can freely move along the track rail while applying a load. This type of motion guide device is used in, for example, linear guide portions such as the X axis, the Y axis, and the Z axis in various machine tools and industrial machines. There are various usage environments of the motion guide device depending on the application of the machine used. For example, in a machine tool for metal processing, a water-soluble coolant falls on the track rail, and in a machine tool for wood processing, fine powder adheres to the track rail. In order to ensure smooth movement of the moving block relative to the track rail even in such a harsh environment, it is necessary to prevent foreign matter adhering to the track rail from entering the moving block. There is provided a dustproof member that seals a gap with the moving block.
　この防塵部材としては、例えば特許文献１に開示されるものが知られている。かかる防塵部材は、前記移動ブロックに対してその移動方向の前後に取り付けられた一対の接触スクレーパと、これら一対の接触スクレーパの間で軌道レールの長手方向に沿って前記移動ブロックの側面に取り付けられたサイドスクレーパとを備えている。 As this dustproof member, for example, one disclosed in Patent Document 1 is known. The dust-proof member is attached to a side surface of the moving block along the longitudinal direction of the track rail between the pair of contact scrapers attached to the moving block before and after the moving direction. Side scraper.
前記接触スクレーパは前記移動ブロックに固定されるケーシングの内部にフェルト等からなる板状の拭き取り体を配置したものである。板状に形成された拭き取り体はその表裏面が前記軌道レールの長手方向と直交するように配置されて、当該軌道レールの表面に接触している。このため、移動ブロックが軌道レールに沿って運動すると、前記ケーシング内の拭き取り体が当該軌道レールの表面に付着した液体や微細粉等の異物を拭き取り、これら異物が軌道レールに付着したまま移動ブロックの内部に侵入するのを防止している。 The contact scraper has a plate-like wiping body made of felt or the like disposed inside a casing fixed to the moving block. The wiping body formed in a plate shape is arranged so that the front and back surfaces thereof are orthogonal to the longitudinal direction of the track rail, and is in contact with the surface of the track rail. For this reason, when the moving block moves along the track rail, the wiping body in the casing wipes off foreign matters such as liquid and fine powder adhering to the surface of the track rail, and the moving block remains attached to the track rail. Is prevented from entering the inside.
　また、前記サイドスクレーパも移動ブロックに固定されるケーシングの内部に板状の拭き取り体を配置したものであり、かかる拭き取り体は軌道レールの長手方向に沿って当該軌道レールと接触している。このサイドスクレーパは前記接触スクレーパのように異物を拭き取る作用は殆ど発揮しないが、軌道レールの長手方向に沿って当該軌道レールと移動ブロックとの間に存在する隙間を塞いでおり、異物が当該隙間から移動ブロックの内部に侵入するのを防止している。 The side scraper also has a plate-like wiping body arranged inside a casing fixed to the moving block, and the wiping body is in contact with the track rail along the longitudinal direction of the track rail. This side scraper does not exhibit the effect of wiping off foreign matter like the contact scraper, but closes the gap existing between the track rail and the moving block along the longitudinal direction of the track rail, and the foreign matter is not covered by the gap. From entering the inside of the moving block.

　特許文献１に示された従来の防塵構造では、前記サイドスクレーパのケーシングを前記移動ブロックに対してボルトで固定しており、その際に当該サイドスクレーパのケーシングの長手方向の端部は前記移動ブロックの前後に配置された接触スクレーパのケーシングと一部で重なっている。しかし、前記接触スクレーパのケーシング及びサイドスクレーパのケーシングはそれぞれが硬質な材料で成形されているため、ボルトを確実に締結した場合でも両者の間に僅かに隙間が生じる可能性があった。また、前記接触スクレーパの拭き取り体と前記サイドスクレーパの拭き取り体とは接触しておらず、前記軌道レールに付着した微細粉や液体等が前記接触スクレーパのケーシングとサイドスクレーパのケーシングとの隙間から移動ブロックの内部に侵入してしまう懸念があった。 In the conventional dustproof structure shown in Patent Document 1, the casing of the side scraper is fixed to the moving block with bolts, and at that time, the end portion of the casing of the side scraper is in the longitudinal direction. It overlaps with a part of the casing of the contact scraper arranged before and after. However, since the casing of the contact scraper and the casing of the side scraper are each formed of a hard material, even when the bolt is securely fastened, there may be a slight gap between the two. Further, the wiper body of the contact scraper and the wiper body of the side scraper are not in contact, and fine powder or liquid adhering to the track rail moves from the gap between the casing of the contact scraper and the casing of the side scraper. There was concern that it would break into the block.
　本発明はこのような着眼からなされたものであり、その目的とするところは、移動ブロックと軌道レールとの隙間を当該移動ブロックの周囲に沿って完全に密封し、当該移動ブロックの内部に微細粉等の異物が侵入するのを防止し、もって軌道レールに対する移動ブロックの円滑な運動を長期にわたって確保することが可能な運動案内装置の防塵構造を提供することにある。 The present invention has been made from such a viewpoint, and the object of the present invention is to completely seal the gap between the moving block and the track rail along the periphery of the moving block, and to finely divide the moving block. An object of the present invention is to provide a dust-proof structure for a motion guide device that can prevent foreign matters such as powder from entering and thereby ensure a smooth motion of a moving block with respect to a track rail over a long period of time.
　すなわち、本発明は、軌道レールと、防塵組立体を有すると共に前記軌道レールに沿って運動自在な移動ブロックとを備えた運動案内装置であって、前記防塵組立体は、前記移動ブロックの進行方向端部に設けられる端部防塵部材と、移動ブロックの長手方向に沿って設けられる側面防塵部材とから構成されている。前記端部防塵部材は、所定の厚みを有する板状に形成されると共に前記移動ブロックの進行方向端部における当該移動ブロックと前記軌道レールとの隙間を塞いで当該軌道レールに面接触する端部拭き取り体と、前記端部拭き取り体を前記移動ブロックに保持するための端部ケースとを備えている。一方、前記側面防塵部材は、所定の厚みを有する板状に形成されて前記軌道レールの長手方向に沿って当該軌道レールと面接触する側面拭き取り体と、前記側面拭き取り体を前記移動ブロックに保持する側面プレートとを備えている。そして、前記側面拭き取り体は前記端部拭き取り体と面接触している。 That is, the present invention is a motion guide device including a track rail and a moving block having a dustproof assembly and movable along the track rail, wherein the dustproof assembly is in a traveling direction of the moving block. It is comprised from the edge part dustproof member provided in an edge part, and the side dustproof member provided along the longitudinal direction of a movement block. The end dustproof member is formed in a plate shape having a predetermined thickness, and closes a gap between the moving block and the track rail at an end portion in the moving direction of the moving block, and an end portion that is in surface contact with the track rail A wiping body and an end case for holding the end wiping body on the moving block are provided. On the other hand, the side dustproof member is formed in a plate shape having a predetermined thickness, and holds the side surface wiper in contact with the track rail along the longitudinal direction of the track rail, and the side wiper on the moving block. And a side plate. The side surface wiper is in surface contact with the end wiper.
　以上のように構成された本発明の防塵構造によれば、前記移動ブロックの進行方向の端部には前記軌道レールの表面に面接触する端部拭き取り体を配置する一方、前記移動ブロックの長手方向に沿って前記軌道レールの表面に面接触する側面拭き取り体を配置し、これら端部拭き取り体と側面拭き取り体とを互いに面接触させているので、端部拭き取り体と側面拭き取り体との間に隙間が形成されるのを防止して、両者の連続性を確保することができ、移動ブロックと軌道レールとの隙間を当該移動ブロックの周囲に沿って完全に密封することが可能となる。これにより、当該移動ブロックの内部に微細粉等の異物が侵入するのを確実に防止して、軌道レールに対する移動ブロックの円滑な運動を長期にわたって確保することが可能となる。 According to the dust-proof structure of the present invention configured as described above, the end wiping body that is in surface contact with the surface of the track rail is disposed at the end in the traveling direction of the moving block, while the length of the moving block is long.

　以下において、添付図面を用いながら本発明を適用した運動案内装置の実施形態を説明する。 Hereinafter, an embodiment of a motion guide device to which the present invention is applied will be described with reference to the accompanying drawings.
　図１及び図２は本発明を適用した運動案内装置の第一実施形態を示すものである。この運動案内装置１は、長手方向に沿って転動体の転走面２０が形成された軌道レール２と、多数の転動体を介して前記軌道レール２に組み付けられると共に当該転動体の無限循環路を内蔵した移動ブロック３とから構成されている。前記転動体が前記軌道レール２の転走面２０を転走しながら前記無限循環路を循環することにより、前記移動ブロック３が当該軌道レール２の長手方向に沿って自在に運動することが可能となっている。尚、前記移動ブロック３としては、転動体を介して軌道レール２に組み付けられたものに限らず、低摩擦係数の滑り接触子を介して軌道レール２に組み付けられたものであっても良い。 1 and 2 show a first embodiment of a motion guide apparatus to which the present invention is applied. The motion guide device 1 is assembled to the track rail 2 having a rolling surface 20 of a rolling element formed along the longitudinal direction, and the track rail 2 through a number of rolling elements, and an infinite circulation path of the rolling element. And a moving block 3 having a built-in. The moving block 3 can freely move along the longitudinal direction of the track rail 2 as the rolling element circulates in the endless circuit while rolling on the rolling surface 20 of the track rail 2. It has become. The moving block 3 is not limited to the one mounted on the track rail 2 via a rolling element, but may be one mounted on the track rail 2 via a low friction coefficient sliding contact.
　また、前記移動ブロック３には防塵組立体６が装着されている。この防塵組立体６は、前記移動ブロック３に対してその進行方向の前後に配置される一対の端部防塵部材７と、前記軌道レール２の長手方向に沿った板状に形成されて前記移動ブロック３の下側に配置された一対の側面防塵部材８とから構成されている。これら端部防塵部材７及び側面防塵部材８を組み合わせた防塵組立体６は、前記軌道ブロック３と前記軌道レール２との隙間を外部に対して密封し、この運動案内装置１が使用される種々の使用環境下で、軌道レール２に付着した微細粉や各種液体が前記移動ブロック３の内部に侵入するのを防止している。 Further, a dustproof assembly 6 is attached to the moving block 3. The dust-proof assembly 6 is formed in a plate shape along the longitudinal direction of the track rail 2 and a pair of end dust-proof members 7 disposed in the front-rear direction of the moving block 3 in the moving direction. It is comprised from a pair of side surface dust-proof member 8 arrange | positioned under the block 3. As shown in FIG. The dust-proof assembly 6 in which the end dust-proof member 7 and the side dust-proof member 8 are combined seals the gap between the track block 3 and the track rail 2 to the outside, and the motion guide device 1 is used in various ways. Thus, the fine powder and various liquids adhering to the track rail 2 are prevented from entering the inside of the moving block 3.
　前記軌道レール２は断面略矩形状に形成されており、その両側面には凹部が夫々形成されている。各凹部の上下には前記転動体の転走面２０が形成されており、軌道レール２全体では４条の転走面２０が形成されている。各転走面２０は、例えば、軌道レール２の底面２１に対して４５°の角度で傾斜しており、前記凹部の上側に位置する転走面２０は斜め下方へ４５°の角度で向く一方、下側に位置する転走面２０は斜め上方へ４５°の角度で向いている。また、かかる軌道レール２には長手方向に沿って所定の間隔で固定ボルトの取付け孔２２が形成されており、当該軌道レール２を機械装置などに敷設する際に利用される。この取り付け孔２２を介して前記移動ブロック３の内部に異物が侵入するのを防止するため、実際にこの運動案内装置を使用する際には、前記取り付け孔２２は固定ボルトを締結した後に円板状の閉塞キャップで塞がれる。 The track rail 2 is formed to have a substantially rectangular cross section, and concave portions are formed on both side surfaces thereof. Rolling surfaces 20 of the rolling elements are formed above and below each recess, and four rolling surfaces 20 are formed in the entire track rail 2. Each rolling surface 20 is inclined at an angle of 45 ° with respect to the bottom surface 21 of the track rail 2, for example, and the rolling surface 20 located above the concave portion is inclined downward at an angle of 45 °. The lower rolling surface 20 faces obliquely upward at an angle of 45 °. The track rail 2 has fixing bolt mounting holes 22 formed at predetermined intervals along the longitudinal direction, and is used when the track rail 2 is laid on a mechanical device or the like. In order to prevent foreign matter from entering the inside of the moving block 3 through the mounting hole 22, when the motion guide device is actually used, the mounting hole 22 is disc-shaped after fastening a fixing bolt. It is closed with a shaped blocking cap.
　尚、前記軌道レール２に対する転走面２０の配置、傾斜角度及びその条数は、前記移動ブロック３に必要とされる負荷能力に応じて適宜設計変更することができる。また、この例では前記転動体としてローラを用いているので、前記転走面２０は平面状に仕上られているが、転動体としてボールを用いる場合には、前記転走面は長手方向に垂直な断面が曲面状に仕上げられることになる。 Note that the arrangement, inclination angle, and number of strips of the rolling surface 20 with respect to the track rail 2 can be appropriately changed according to the load capacity required for the moving block 3. In this example, since the roller is used as the rolling element, the rolling surface 20 is finished in a flat shape. However, when a ball is used as the rolling element, the rolling surface is perpendicular to the longitudinal direction. A simple cross-section is finished into a curved surface.
　一方、前記移動ブロック３はワークテーブル等の搬送対象物を搭載する取付け面３０を有すると共に、当該移動ブロック３の前記軌道レール２に対する進行方向の前後には一対の潤滑油供給装置４が装着されている。この潤滑油供給装置４は潤滑油を内蔵しており、軌道レール２に対して前記移動ブロック３が進行すると、かかる進行に伴って当該軌道レール２の転走面２０に対して潤滑油を適量ずつ塗布する。 On the other hand, the moving block 3 has a mounting surface 30 on which a conveyance object such as a work table is mounted, and a pair of lubricating oil supply devices 4 are mounted on the moving block 3 before and after the moving direction with respect to the track rail 2. ing. This lubricating oil supply device 4 contains lubricating oil. When the moving block 3 advances with respect to the track rail 2, an appropriate amount of lubricating oil is applied to the rolling surface 20 of the track rail 2 as the moving block 3 advances. Apply one by one.
また、各潤滑油供給装置４の外側には２枚一組のシール部材５が装着されている。各シール部材５は先端部が薄く成形されたウレタンゴム製のシールリップを有し、かかるシールリップの先端は前記転走面２０を含めた軌道レール２の表面に対して撓みながら線接触している。これらシール部材５は主として潤滑油を移動ブロック３内に保持する機能を担っており、そのために当該シール部材５は前記潤滑油供給装置４の外側に配置されている。また、前記シールリップが軌道レール２の表面に摺接していることから、これらシール部材５は前記防塵組立体６をすり抜けてしまった微細粉や液体等の異物を軌道レール２の表面から排除し、かかる異物が前記移動ブロック３内に侵入するのを防止する機能も発揮している。但し、この異物排除の機能に関しては前記防塵組立体６、特に前記端部防塵部材７の方が上回っており、前記シール部材５が発揮する異物排除機能はあくまでも防塵組立体６の補助的なものである。尚、軌道レール２に付着する微細粉等の異物が少ない環境であれば、前記シール部材５は必ずしも２枚を重ねて設ける必要はなく、１枚のみを前記潤滑油供給装置４の外側に装着してもよい。 In addition, a set of two seal members 5 is attached to the outside of each lubricating oil supply device 4. Each seal member 5 has a urethane rubber seal lip with a thin tip, and the tip of the seal lip is in line contact with the surface of the track rail 2 including the rolling surface 20 while being bent. Yes. These seal members 5 mainly have a function of holding the lubricating oil in the moving block 3, and for this purpose, the sealing member 5 is disposed outside the lubricating oil supply device 4. Further, since the seal lip is in sliding contact with the surface of the track rail 2, these seal members 5 remove from the surface of the track rail 2 foreign matters such as fine powder and liquid that have passed through the dustproof assembly 6. The function of preventing such foreign matter from entering the moving block 3 is also exhibited. However, with respect to the function of removing the foreign matter, the dust-proof assembly 6, particularly the end dust-proof member 7, is superior, and the foreign-material removal function exhibited by the seal member 5 is only an auxiliary of the dust-proof assembly 6. It is. In an environment where there is little foreign matter such as fine powder adhering to the track rail 2, the seal member 5 does not necessarily have to be provided in two layers, and only one is attached to the outside of the lubricating oil supply device 4. May be.
　前記潤滑油供給装置４はこの運動案内装置の使用環境に応じて任意に装着又は非装着が選択される。例えば、移動ブロック３に対してグリースを封入し、かかるグリースのみで前記軌道レール２を転走する転動体を十分に潤滑できるのであれば、前記潤滑油供給装置４は省略することができる。その場合、前記シール部材５は前記移動ブロック３に対して直接固定される。 The mounting or non-mounting of the lubricating oil supply device 4 is arbitrarily selected according to the usage environment of the motion guide device. For example, if the grease is enclosed in the moving block 3 and the rolling elements rolling on the track rail 2 can be sufficiently lubricated with only such grease, the lubricating oil supply device 4 can be omitted. In that case, the seal member 5 is directly fixed to the moving block 3.
　尚、図１では前記移動ブロックに対する前記潤滑油供給装置４、前記シール部材５、前記端部防塵部材６０の組み合わせが理解し易いよう、移動ブロック３の一方の端部についてはこれらを分解した状態を示している。また、前記防塵組立体６を構成する一対の側面防塵部材８に関しては、一方の側面防塵部材８のみを移動ブロック３から取り外して図１中に描いてある。 In FIG. 1, one end of the moving block 3 is disassembled so that the combination of the lubricant supply device 4, the seal member 5, and the end dustproof member 60 with respect to the moving block can be easily understood. Is shown. Further, regarding the pair of side dustproof members 8 constituting the dustproof assembly 6, only one side dustproof member 8 is removed from the moving block 3 and depicted in FIG.
　次に、前記防塵組立体６の具体的構成について説明する。 Next, a specific configuration of the dustproof assembly 6 will be described.
　前述したように、前記防塵組立体６は一対の端部防塵部材７及び一対の側面防塵部材８とから構成されている。図２は前記端部防塵部材７の詳細を示す分解斜視図である。この端部防塵部材７は、合成ゴムの発泡体からなる複数枚（図２に示す例では３枚）の端部拭き取り体７０と、互いに隣接する端部拭き取り体７０の間に配置されたスペーサ板７１と、これら端部拭き取り体７０及びスペーサ板７１の収容室７２を有する端部ケース７３とから構成されている。 As described above, the dustproof assembly 6 includes a pair of end dustproof members 7 and a pair of side dustproof members 8. FIG. 2 is an exploded perspective view showing details of the end dustproof member 7. The end dustproof member 7 is a spacer disposed between a plurality of end wipers 70 (three in the example shown in FIG. 2) made of a synthetic rubber foam and the end wipers 70 adjacent to each other. It is comprised from the board 71 and the edge part case 73 which has the storage chamber 72 of these edge part wipers 70 and the spacer board 71. As shown in FIG.
　各端部拭き取り体７０は所定の厚みを有する板状に成形されており、中央には前記軌道レール２が通過する凹所が設けられている。前記凹所を囲む端部拭き取り体７０の内側面は軌道レール２の表面と平行に設けられており、軌道レール２の表面に面接触する拭き取り面７０ａを構成している。前記拭き取り面７０ａが前記軌道レール２の表面に対して隙間なく摺接するよう、前記凹所は軌道レール２の断面形状よりも僅かに小さく形成されており、当該拭き取り面７０ａは僅かな締め代を伴って軌道レール２に接している。 Each end wiping body 70 is formed in a plate shape having a predetermined thickness, and a recess through which the track rail 2 passes is provided at the center. An inner surface of the end wiping body 70 surrounding the recess is provided in parallel with the surface of the track rail 2, and constitutes a wiping surface 70 a that is in surface contact with the surface of the track rail 2. The recess is formed slightly smaller than the cross-sectional shape of the track rail 2 so that the wiping surface 70a is in sliding contact with the surface of the track rail 2 without any gap, and the wiping surface 70a has a slight tightening allowance. Accordingly, it is in contact with the track rail 2.
　また、前記スペーサ板７１は前記端部拭き取り体７０略同じ大きさに形成された金属製又は合成樹脂製の薄板であり、中央には前記軌道レール２が通過する凹所が設けられている。但し、このスペーサ板７１は前記軌道レール２に接することがないよう、前記凹所が軌道レール２の断面形状よりも僅かに大きく形成されている。このスペーサ板７１は前後に隣接する２枚の端部拭き取り体７０を分離し、一方の端部拭き取り体７０の汚れが他方の端部拭き取り体７０に転移するのを防止する。これにより、例えば軌道レール２に付着していた水溶性クーラント液が前記移動ブロック３の進行方向の最も外側に位置していた端部拭き取り体７０にしみ込んだとしても、かかるクーラント液が隣接する２枚目の端部拭き取り体７０に即座にしみ込んでしまうことはなく、端部防塵部材７による軌道レール２の清浄作用を長期にわたって維持することができる。 Further, the spacer plate 71 is a thin plate made of metal or synthetic resin formed in substantially the same size as the end wiping body 70, and a recess through which the track rail 2 passes is provided in the center. However, the spacer plate 71 is formed so that the recess is slightly larger than the cross-sectional shape of the track rail 2 so as not to contact the track rail 2. The spacer plate 71 separates the two end wipers 70 adjacent to each other in the front-rear direction and prevents the dirt on one end wiper 70 from being transferred to the other end wiper 70. Thereby, for example, even if the water-soluble coolant liquid adhering to the track rail 2 has soaked into the end wiping body 70 located on the outermost side in the moving direction of the moving block 3, the coolant liquid is adjacent 2 The edge wiping body 70 of the sheet is not immediately impregnated, and the cleaning action of the track rail 2 by the end dust proof member 7 can be maintained for a long time.
　これらの端部拭き取り体７０及びスペーサ板７１は交互に重ね合わせた状態で前記端部ケース７３の収容室７２に保持されている。前記端部ケース７３にも前記軌道レール２が通過する凹所が設けられており、当該端部ケース７３は前記スペーサ板７１と同様に前記軌道レール２とは非接触である。また、前記端部ケース７３には前記軌道レール２の側面と対向する位置に保持突片７４が設けられており、かかる保持突片７４は前記端部防塵部材７を軌道レール２から取り外した際に前記端部拭き取り体７０及びスペーサ板７１が収容室７２から抜け落ちるのを防止している。 These end wipes 70 and spacer plates 71 are held in the storage chamber 72 of the end case 73 in a state of being alternately stacked. The end case 73 is also provided with a recess through which the track rail 2 passes, and the end case 73 is not in contact with the track rail 2 in the same manner as the spacer plate 71. The end case 73 is provided with a holding protrusion 74 at a position facing the side surface of the track rail 2, and the holding protrusion 74 is removed when the end dustproof member 7 is removed from the track rail 2. Further, the end wiper 70 and the spacer plate 71 are prevented from falling out of the storage chamber 72.
　この端部防塵部材７は前記端部ケース７３を貫通して前記移動ブロック３に締結される複数の固定ボルトによって当該移動ブロック３に固定される。これら固定ボルトは同時に前記シール部材５及び潤滑油供給装置４も貫通し、当該固定ボルトの締結によって前記端部防塵部材７と移動ブロック３との間に前記シール部材５及び潤滑油供給装置４が保持されるようになっている。 The end dustproof member 7 is fixed to the moving block 3 by a plurality of fixing bolts that pass through the end case 73 and are fastened to the moving block 3. These fixing bolts penetrate the seal member 5 and the lubricating oil supply device 4 at the same time, and the sealing member 5 and the lubricating oil supply device 4 are interposed between the end dustproof member 7 and the moving block 3 by fastening the fixing bolt. It is supposed to be retained.
　一方、図１中に示すように、前記側面防塵部材８は、前記軌道レール２の長手方向に沿って伸びる板状の側面拭き取り体８０と、この側面拭き取り体８０を移動ブロック２に保持する側面プレート８１とから構成されている。前記側面拭き取り体８０は、前記端部拭き取り体７０と同様に合成ゴムの発泡体を所定の厚みを有する板状に成形しており、軌道レール２の長手方向に沿ってその側面に面接触する拭き取り面８０ａを有している。また、この実施形態において、前記側面拭き取り体８０の軌道レール２の長手方向に沿った長さは、当該側面拭き取り体８０の両端部が前記移動ブロック３の両端に設けられた一対の端部防塵部材７と重なる長さに設定されている。 On the other hand, as shown in FIG. 1, the side dust-proof member 8 includes a plate-like side surface wiping body 80 that extends along the longitudinal direction of the track rail 2, and a side surface that holds the side surface wiping body 80 on the moving block 2. And plate 81. The side wiper 80 is formed by molding a synthetic rubber foam into a plate shape having a predetermined thickness in the same manner as the end wiper 70, and is in surface contact with the side surface along the longitudinal direction of the track rail 2. It has a wiping surface 80a. Moreover, in this embodiment, the length along the longitudinal direction of the track rail 2 of the side surface wiping body 80 is such that the both end portions of the side surface wiping body 80 are provided at both ends of the moving block 3. The length overlaps with the member 7.
　図３は前記側面プレート８１を示す斜視図である。前記側面プレート８１は前記側面拭き取り体８０を載せる収容凹部８２を有している。この収容凹部８２の深さは前記側面拭き取り体８０の厚さよりも浅くなっており、前記収容凹部８２に側面拭き取り体８０を配置すると、当該側面拭き取り体８０が側面プレート８１上に僅かに突出するようになっている。また、この側面プレート８１は前記移動ブロック３に対して下側から、すなわち軌道レール２の底面の方向からねじ止めされ、当該側面プレート８１にはその際に利用する複数のねじ孔が設けられている。従って、前記側面プレート８１を移動ブロック３に対して固定すると、前記収容凹部８２に配置された側面拭き取り体８０が当該側面プレート８１と移動ブロック３との間に挟み込まれ、その状態で側面拭き取り体８０の拭き取り面８０ａが軌道レール２の側面に面接触することになる。 FIG. 3 is a perspective view showing the side plate 81. The side plate 81 has an accommodation recess 82 on which the side wiper 80 is placed. The depth of the accommodation recess 82 is shallower than the thickness of the side surface wiping body 80, and when the side surface wiping body 80 is disposed in the accommodation recess 82, the side surface wiping body 80 slightly protrudes on the side plate 81. It is like that. The side plate 81 is screwed to the moving block 3 from below, that is, from the bottom surface of the track rail 2, and the side plate 81 is provided with a plurality of screw holes used at that time. Yes. Therefore, when the side plate 81 is fixed to the moving block 3, the side wiper 80 disposed in the housing recess 82 is sandwiched between the side plate 81 and the moving block 3, and the side wiper is in that state. The 80 wiping surfaces 80 a come into surface contact with the side surfaces of the track rail 2.
　更に、前記側面プレート８１の長手方向の両端には一対の係止突部８３が設けられている。これら係止突部８３は前記端部防塵部材７の端部ケース７３に設けられた溝部７５に嵌合する。このため、前記端部ケース７３を移動ブロック３に固定した状態では、図４に示すように、前記側面プレート８１が前記端部ケース７３に連結され、当該側面プレート８１の端部が前記端部ケース７３によって保持されるようになっている。 Furthermore, a pair of locking projections 83 are provided at both ends of the side plate 81 in the longitudinal direction. These locking projections 83 are fitted into grooves 75 provided in the end case 73 of the end dustproof member 7. Therefore, in the state where the end case 73 is fixed to the moving block 3, as shown in FIG. 4, the side plate 81 is connected to the end case 73, and the end of the side plate 81 is connected to the end portion. The case 73 is held.
　図５及び図６は、前記端部ケース７３と前記側面プレート８１とを連結させた状態における前記軌道レール、前記端部拭き取り体７０及び前記側面拭き取り体８０の三者の接触状態を示す断面図である。 5 and 6 are cross-sectional views showing a contact state between the track rail, the end wiping body 70 and the side wiping body 80 in a state where the end case 73 and the side plate 81 are connected. It is.
　図５は前記端部防塵部材７を前記軌道レール２の長手方向と垂直な方向に沿って切断した断面図である。この図５に示すように、前記端部拭き取り体７０は軌道レール２と隙間なく接触している。このため、前記移動ブロック３が軌道レール２に沿って移動すると、前記端部拭き取り体７０の拭き取り面７０ａが軌道レール２の表面に付着した微細粉や液体などの異物を当該軌道レール２の表面から排除する。また、前記端部拭き取り体７０は合成ゴムの発泡体から成形されているので、軌道レール２の表面に付着した液体を毛管現象で吸い取る効果も発揮する。また、軌道レール２に設けられた固定ボルトの取り付け孔２２は閉塞キャップ２３で塞がれており、前記端部拭き取り体７０は前記閉塞キャップ２３に対しても隙間なく接触している。 FIG. 5 is a cross-sectional view of the end dustproof member 7 cut along a direction perpendicular to the longitudinal direction of the track rail 2. As shown in FIG. 5, the end wiping body 70 is in contact with the track rail 2 without a gap. For this reason, when the moving block 3 moves along the track rail 2, the wiping surface 70 a of the end wiping body 70 removes foreign matter such as fine powder or liquid adhering to the surface of the track rail 2. To eliminate. Further, since the end wipe 70 is formed from a synthetic rubber foam, it also exhibits an effect of sucking the liquid adhering to the surface of the track rail 2 by capillary action. The fixing bolt mounting hole 22 provided in the track rail 2 is closed with a closing cap 23, and the end wiper 70 is in contact with the closing cap 23 without any gap.
　一方、前記端部ケース７３の収容室７２の下方には前記保持突片７４と軌道レール２の側面との間に開口部が設けられており、この開口部を通じて前記収容室７２内の端部拭き取り体７０が前記側面防塵部材８の側面拭き取り体８０に接触している。具体的には、図２に示すように、各端部拭き取り体７０には前記開口部に入り込む接続部７６が設けられており、この接続部７６の先端面が図５に示すように前記側面拭き取り体８０に面接触している。 On the other hand, an opening is provided between the holding protrusion 74 and the side surface of the track rail 2 below the storage chamber 72 of the end case 73, and the end of the storage chamber 72 through the opening. The wipe 70 is in contact with the side wipe 80 of the side dust-proof member 8. Specifically, as shown in FIG. 2, each end wiping body 70 is provided with a connecting portion 76 that enters the opening, and the distal end surface of the connecting portion 76 is the side surface as shown in FIG. The wiper 80 is in surface contact.
　また、前記側面拭き取り体８０はその先端の拭き取り面８０ａが軌道レール２の側面と隙間なく面接触しており、しかも当該側面拭き取り体８０の長手方向の両端は前述のように端部拭き取り体７０と面接触しているので、前記移動ブロック３の進行方向の両端に位置する一対の端部防塵部材７の間では、当該移動ブロック３と軌道レール２の側面との隙間が前記側面拭き取り体８０によって完全に塞がれていることになる。すなわち、移動ブロック３の進行方向の両端に位置する一対の端部防塵部材７は軌道レール２の側面に位置する一対の側面防塵部材８によって接続されて防塵組立体６を構成し、前記端部拭き取り体７０の拭き取り面７０ａと側面拭き取り体８０の拭き取り面８０ａとが軌道レール２の周囲で連続した拭き取り面を形成して、移動ブロック３と軌道レール２との隙間を外部から塞いでいる。 Further, the side surface wiper 80 has a wiped surface 80a at the tip thereof in surface contact with the side surface of the track rail 2 without a gap, and both ends in the longitudinal direction of the side surface wiper 80 are end wipers 70 as described above. Between the pair of end dustproof members 7 located at both ends in the traveling direction of the moving block 3, the gap between the moving block 3 and the side surface of the track rail 2 is the side wiper 80. Will be completely blocked. That is, a pair of end dustproof members 7 positioned at both ends in the moving direction of the moving block 3 are connected by a pair of side dustproof members 8 positioned on the side surfaces of the track rail 2 to constitute a dustproof assembly 6, and the end portions The wiping surface 70a of the wiping body 70 and the wiping surface 80a of the side surface wiping body 80 form a continuous wiping surface around the track rail 2 to block the gap between the moving block 3 and the track rail 2 from the outside.
　そして、前述のように、前記端部防塵部材７の端部拭き取り体７０と側面防塵部材８の側面拭き取り体８０とが互いに面接触して、両者の拭き取り面が間断なく連続しているので、仮に前記端部防塵部材７の端部ケース７３と側面防塵部材８の側面プレート８１の端部との間に意図せずして僅かな隙間が生じたとしても、軌道レール２に付着した微細分や液体等の異物が移動ブロック３の内部に侵入するのを防止できる。 And, as described above, the end wiper 70 of the end dustproof member 7 and the side wiper 80 of the side dustproof member 8 are in surface contact with each other, and both wiped surfaces are continuous without interruption. Even if a slight gap occurs unintentionally between the end case 73 of the end dust-proof member 7 and the end of the side plate 81 of the side dust-proof member 8, the minute portion adhering to the track rail 2 will be described. And foreign matter such as liquid can be prevented from entering the moving block 3.
　一方、図６は前記端部防塵部材７の端部ケース７３に収納された３枚の端部拭き取り体７０と前記側面拭き取り体８０との接触状態を示している。この図６に示すように、前記側面プレート８１の収容凹部８２内に配置された側面拭き取り体８０は当該側面プレート８１の上面から僅かに突出しているので、前記側面プレート８１の長手方向の端部を前記端部ケース７３に固定した状態で当該端部ケース７３を前記移動ブロック３に対して固定すると、前記側面拭き取り体８０の長手方向の端部が前記端部拭き取り体７０の接続部７６に対して下方から押しつけられることになる。これにより、前記端部拭き取り体７０と前記側面拭き取り体８０との面接触が一層確実に行われ、両者の間での隙間の発生が防止されている。 On the other hand, FIG. 6 shows a contact state between the three end wipers 70 housed in the end case 73 of the end dustproof member 7 and the side wipers 80. As shown in FIG. 6, the side surface wiper 80 disposed in the receiving recess 82 of the side plate 81 slightly protrudes from the upper surface of the side plate 81, so that the end of the side plate 81 in the longitudinal direction When the end case 73 is fixed to the moving block 3 with the end case 73 fixed to the end case 73, the end portion in the longitudinal direction of the side surface wiping body 80 becomes the connection portion 76 of the end wiping body 70. On the other hand, it will be pressed from below. Thereby, the surface contact with the said edge part wiping body 70 and the said side surface wiping body 80 is performed more reliably, and generation | occurrence | production of the clearance gap between both is prevented.
　更に、前記側面プレート８１の長手方向の端部に設けられた係止突部８３は、図６に示すように、端部ケース７３に設けられた溝部７５に嵌合している。このため、前記側面拭き取り体８０が前記端部拭き取り体７０の接続部７６に対して強く押しつけられたとしても、前記側面プレート８１の端部が押しつけ力の反力で下方に撓んでしまうことはなく、この点においても前記側面拭き取り体８０を前記端部拭き取り体７０に対して確実に面接触させることができる。 Furthermore, the locking projection 83 provided at the end in the longitudinal direction of the side plate 81 is fitted in a groove 75 provided in the end case 73 as shown in FIG. For this reason, even if the side surface wiping body 80 is strongly pressed against the connection portion 76 of the end portion wiping body 70, the end of the side plate 81 is bent downward due to the reaction force of the pressing force. In this respect also, the side surface wiping body 80 can be reliably brought into surface contact with the end portion wiping body 70.
　このように、前記端部防塵部材７の端部ケース７３と側面防塵部材８の側面プレート８１とを組み合わせて防塵組立体６を構成した場合に、前記端部拭き取り体７０と側面拭き取り体８０とが単に面接触するのではなく、両者が互いに圧接しながら面接触するように構成しているので、前記端部拭き取り体７０と側面拭き取り体８０との連続性を一層確固たるものとすることが可能となっている。 Thus, when the dustproof assembly 6 is configured by combining the end case 73 of the end dustproof member 7 and the side plate 81 of the side dustproof member 8, the end wiper 70 and the side wiper 80 are However, it is possible to make the continuity between the end wiping body 70 and the side wiping body 80 even more firm because the two are not in surface contact but in surface contact with each other. It has become.
　図６に示す実施形態では、前記端部防塵部材７が３枚の端部拭き取り体７０を有しており、そのうち２枚の端部拭き取り体７０は前記側面拭き取り体８０に圧接している。このように複数枚の端部拭き取り体７０を側面拭き取り体８０と面接触させることで、前記端部防塵部材７と側面防塵部材８との隙間を確実に排除し、前記移動ブロック３の内部に対する異物の侵入を防止することが可能となる。 In the embodiment shown in FIG. 6, the end dust-proof member 7 has three end wipers 70, and the two end wipers 70 are in pressure contact with the side wiper 80. In this way, the plurality of end wipers 70 are brought into surface contact with the side wiper 80, so that the gap between the end dustproof member 7 and the side dustproof member 8 can be surely eliminated, and the inside of the movable block 3 can be removed. It becomes possible to prevent intrusion of foreign matter.
　また、前記端部ケース７３内には複数枚の端部拭き取り体７０が配置されているが、前記移動ブロック３の進行方向の最も外側に配置された端部拭き取り体７０は、前記側面防塵部材８の側面拭き取り体８０の長手方向の外側において前記側面プレート８１に接触している。総ての端部拭き取り体７０を前記側面プレート８１に接触させることなく前記側面拭き取り体８０に圧接させても良いのだが、当該端部拭き取り体７０は側面拭き取り体８０に圧接して僅かな弾性変形を伴っており、かかる弾性変形の影響で当該端部拭き取り体７０と軌道レール２との接触状態が不安定になる懸念がある。 Further, a plurality of end wipers 70 are arranged in the end case 73, but the end wipers 70 arranged on the outermost side in the moving direction of the moving block 3 are the side dust-proof members. 8 is in contact with the side plate 81 on the outer side in the longitudinal direction of the side surface wiping body 80. Although all the end wipers 70 may be pressed against the side wiper 80 without contacting the side plate 81, the end wiper 70 is pressed against the side wiper 80 and slightly elastic. There is a concern that the contact state between the end wiping body 70 and the track rail 2 becomes unstable due to the elastic deformation.
　従って、前記移動ブロック３の進行方向の最も外側に配置された端部拭き取り体７０に関しては、前記側面拭き取り体８０の長手方向の外側において前記側面プレート８１と接触する領域を設けてある。これにより、最も外側に配置された端部拭き取り体７０はその拭き取り面７０ａが軌道レール２と確実に面接触し、前記端部防塵部材７がその機能、すなわち軌道レール２に付着した異物を排除するという機能を確実に発揮することが可能となる。 Therefore, with respect to the end wiping body 70 disposed on the outermost side of the moving block 3 in the traveling direction, an area in contact with the side plate 81 is provided on the outer side in the longitudinal direction of the side wiping body 80. As a result, the end wiping body 70 arranged on the outermost side has its wiping surface 70a in reliable surface contact with the track rail 2, and the end dust proof member 7 eliminates the function, that is, the foreign matter attached to the track rail 2. It is possible to reliably exert the function of performing.
　尚、前記端部拭き取り体７０及び側面拭き取り体８０は、発泡体に対して事前に潤滑油を含浸させたものであってもよい。これら端部拭き取り体７０及び側面拭き取り体８０は軌道レール２に対して面接触しているが、潤滑油を含浸させることで軌道レール２に対する摺動抵抗を減じることができ、軌道レール２に対する移動ブロック３の運動に作用する抵抗を抑えることが可能となる。 The end wiping body 70 and the side wiping body 80 may be obtained by impregnating a foam with a lubricating oil in advance. Although the end wiper 70 and the side wiper 80 are in surface contact with the track rail 2, the sliding resistance with respect to the track rail 2 can be reduced by impregnating the lubricant, and the movement with respect to the track rail 2 can be reduced. It is possible to suppress the resistance acting on the motion of the block 3.
