Description

本発明は、建築作業現場などで使用される、レーザービーム投射器を利用した墨出し装置に関するものである。   The present invention relates to a marking device using a laser beam projector used in a construction work site or the like.

この種の墨出し装置には、その設置床面の傾斜に関係なくレーザービーム投射器が鉛直姿勢（水平姿勢）に保持された状態で使用できるように、各種のレベル出し機構が採用されている。例えば、特許文献１に示される墨出し装置は、ジャイロ機構を利用してレーザービーム投射器を吊り下げ、重力によってレーザービーム投射器が鉛直姿勢に保持されるように構成したものである。又、特許文献を開示することはできないが、特許文献１に示される墨出し装置を更に改善したものとして、１点を支点に任意の方向に首振り運動可能な可動台にレーザービーム投射器を支持させ、この可動台から互いに直交するＸＹ２方向に被動ピンを突設させ、これら各被動ピンを上下から挟持して昇降する昇降体を介して前記可動台をＸＹ２方向にそれぞれ各別に傾動させる２つの可動台姿勢制御装置が設けられた墨出し装置も考えられた。この姿勢制御装置利用の墨出し装置は、前記可動台のＸＹ２方向それぞれの姿勢のずれを電子式水準器などの適当なセンサーによって検出し、この検出情報に基づいて前記２つの可動台姿勢制御装置を自動運転させることにより、前記可動台のＸＹ２方向それぞれの姿勢のずれを自動的に矯正し、レーザービーム投射器を所期の鉛直姿勢（水平姿勢）に保持させようとするものである。
実用新案登録第３０８５４９６号公報 Various types of leveling mechanisms are employed in this type of marking device so that the laser beam projector can be used in a vertical position (horizontal position) regardless of the inclination of the installation floor. . For example, the ink marking device disclosed in Patent Document 1 is configured such that a laser beam projector is suspended using a gyro mechanism, and the laser beam projector is held in a vertical posture by gravity. Further, although the patent document cannot be disclosed, the laser beam projector is mounted on a movable table that can swing in any direction with one point as a fulcrum, as a further improvement of the ink marking device disclosed in Patent Document 1. The movable pins are supported and protruded from the movable base in the XY2 directions orthogonal to each other, and the movable bases are tilted separately in the XY2 directions via lifts that sandwich the driven pins from above and below and move up and down. An inking device equipped with two movable platform control devices was also considered. The marking device using the attitude control device detects the deviation of the attitude of the movable table in the XY2 directions by an appropriate sensor such as an electronic level, and based on the detection information, the two movable table attitude control devices. Is automatically operated to automatically correct the deviation of the position of the movable table in the X and Y directions, and to keep the laser beam projector in the intended vertical position (horizontal position).
Utility Model Registration No. 3085496

特許文献１に記載された墨出し装置に対して、上記の姿勢制御装置利用の墨出し装置は、レーザービーム投射器の姿勢を強制的且つ自動的に矯正させることができ、高精度の墨出しが可能なものであるが、実用面では次のような問題点があった。即ち、レーザービーム投射器を支持する可動台と各姿勢制御装置とが可動台側の被動ピンと姿勢制御装置側の二股状の昇降体とでつながった構成であるから、この墨出し装置が建築作業現場で取り扱われるとき、或いは輸送中などに受ける不測な衝撃、例えば不注意で倒したときなどに墨出し装置に作用する衝撃は、可動台側の被動ピンと姿勢制御装置側の二股状の昇降体との嵌合部に集中し、強度的に弱い二股状の昇降体が破損する恐れがあった。   In contrast to the inking device described in Patent Document 1, the inking device using the above-described attitude control device can forcibly and automatically correct the attitude of the laser beam projector, and achieves high-precision inking. However, there are the following problems in practical use. That is, since the movable table that supports the laser beam projector and each posture control device are connected by the movable pin on the movable table side and the bifurcated lifting body on the posture control device side, this marking device is used for building work. Unexpected impacts when handling on site or during transportation, such as impacts that act on the marking device when inadvertently knocked down, are driven pins on the movable base and bifurcated lifting bodies on the posture control device The bifurcated lifting body, which is weak in strength, may be damaged.

本発明は上記のような従来の問題点を解消し得る墨出し装置を提供することを目的とするものであって、その手段を後述する実施形態の参照符号を付して示すと、基台３に対し１点を支点に任意の方向に首振り運動可能に支持された可動台９にレーザービーム投射器１４，１５が支持されると共に、当該可動台９から互いに直交するＸＹ２方向に被動ピン２２Ａ，２２Ｂが突設され、これら各被動ピン２２Ａ，２２Ｂを上下から挟持して昇降する昇降体２６を介して前記可動台９をＸＹ２方向にそれぞれ各別に傾動させる２つの可動台姿勢制御装置２１Ａ，２１Ｂが設けられた墨出し装置において、前記被動ピン２２Ａ，２２Ｂに、少なくとも上下方向に弾性変位可能な緩衝作用部３５が設けられた構成となっている。   An object of the present invention is to provide an inking device capable of solving the above-described conventional problems. When the means is shown with reference numerals of embodiments to be described later, The laser beam projectors 14 and 15 are supported on a movable base 9 supported so as to be able to swing in any direction with one point as a fulcrum with respect to 3, and a driven pin extends in an XY2 direction perpendicular to the movable base 9. 22A and 22B are projected, and two movable platform posture control devices 21A are provided for tilting the movable platform 9 in the XY2 directions separately through a lifting body 26 that lifts and lowers the driven pins 22A and 22B from above and below. , 21B, the driven pins 22A, 22B are provided with a buffering action portion 35 that can be elastically displaced at least in the vertical direction.

上記構成の本発明を実施するについて、具体的には請求項２に記載の構成のように、前記被動ピン２２Ａ，２２Ｂを、前記昇降体２６に挟持される先端部材３６と前記可動台９への取付部材３７、及びこの両者を連結するコイルスプリング３８から構成することができる。この場合、請求項３に記載のように、前記コイルスプリング３８には、前記先端部材３６と取付部材３７とを互いに軸方向に圧接させる方向に初期圧縮応力を与えておくのが望ましい。   In carrying out the present invention having the above-described configuration, specifically, the driven pins 22A and 22B are connected to the tip member 36 and the movable base 9 sandwiched by the elevating body 26 as in the configuration of the second aspect. Mounting member 37, and a coil spring 38 that connects both of them. In this case, it is desirable that an initial compressive stress is applied to the coil spring 38 in a direction in which the tip member 36 and the mounting member 37 are pressed against each other in the axial direction.

又、請求項４に記載のように、前記被動ピン２２Ａ，２２Ｂを、前記昇降体２６に挟持されるピン本体４４と前記可動台９への取付部材４５、及び弾性リング４６から構成し、前記取付部材４５には、ピン本体４４の基部側が上下動可能に嵌合する凹溝部４７を設け、前記凹溝部４７に嵌合する状態のピン本体４４の基部と取付部材４５とにわたって前記弾性リング４６を外嵌させて両者を一体化することができる。   According to a fourth aspect of the present invention, the driven pins 22A and 22B are composed of a pin body 44 sandwiched by the elevating body 26, a mounting member 45 to the movable base 9, and an elastic ring 46, The mounting member 45 is provided with a concave groove portion 47 in which the base side of the pin main body 44 is fitted so as to be movable up and down, and the elastic ring 46 extends between the base portion of the pin main body 44 and the mounting member 45 in a state of fitting in the concave groove portion 47. And can be integrated with each other.

上記構成の本発明に係る墨出し装置によれば、レーザービーム投射器を支持する可動台と各姿勢制御装置とをつなぐ各被動ピンに設けられた少なくとも上下方向に弾性変位可能な緩衝作用部が、この墨出し装置に不測に作用する衝撃を吸収することになり、当該被動ピンを上下から挟持する昇降体を破損させてしまったり、当該昇降体を昇降駆動する駆動系に無理な応力が作用して変形し、円滑で高精度の昇降駆動が行えなくなるような不都合が生じるのを解消できる。尚、緩衝作用部が上下方向にのみ弾性変位可能なものであっても、水平横方向に関しては、被動ピンを昇降駆動する昇降体が当該被動ピンを上下から挟持するものであって、この両者間において或る程度の水平横方向の相対移動が可能であるから、実用上問題はない。   According to the marking device according to the present invention having the above-described configuration, the buffer action unit that is elastically displaceable at least in the vertical direction is provided on each driven pin that connects the movable base that supports the laser beam projector and each posture control device. This will absorb the shock that acts unexpectedly on the marking device, which may damage the lifting body that sandwiches the driven pin from above and below, or exerts unreasonable stress on the drive system that drives the lifting body up and down. Therefore, it is possible to eliminate the inconvenience that the deformation and the smooth and highly accurate lifting drive cannot be performed. Even if the buffering action part can be elastically displaced only in the vertical direction, in the horizontal and horizontal direction, the lifting body that drives the driven pin to lift and lower holds the driven pin from above and below. Since a certain amount of relative horizontal and horizontal movement is possible, there is no practical problem.

尚、本発明は、例えば被動ピンの昇降体に挟持される先端部領域を比較的硬度のあるゴム製の柱状部材で構成する方法や、可動台への取付部材と昇降体に挟持される先端部材との間を比較的硬度のあるゴム製の柱状部材で連結一体化する方法などでも実施することができるが、請求項２に記載の構成によれば、必要十分な強度を被動ピンに有せしめながら、当該被動ピンの周囲３６０度何れの方向に対しても緩衝作用を持たせることができ、所期の目的をより一層確実に達成させることができる。この場合、請求項３に記載の構成によれば、被動ピンに必要な剛性を容易に与えることができる。   In the present invention, for example, a method in which the tip end region sandwiched between the lifting and lowering bodies of the driven pin is constituted by a rubber columnar member having a relatively hard hardness, or a tip mounted between the mounting member on the movable base and the lifting body. Although it can also be implemented by a method of connecting and integrating with a member made of rubber with a relatively hard rubber member, according to the configuration of claim 2, the driven pin has a necessary and sufficient strength. However, it is possible to provide a buffering action in any direction of 360 degrees around the driven pin, and the intended purpose can be achieved more reliably. In this case, according to the configuration described in claim 3, the required rigidity can be easily given to the driven pin.

又、請求項４に記載の構成によれば、弾性リングを利用して安価に実施することができ、しかも当該弾性リングの交換が容易であるから、弾性リングの経年劣化などが懸念される状況に至ったときには簡単容易に当該弾性リングを交換し、長期間にわたって所期の緩衝作用効果を維持させることができる。   Further, according to the configuration of the fourth aspect, the elastic ring can be used at a low cost, and the elastic ring can be easily replaced. Therefore, the elastic ring can be exchanged easily and easily, and the desired buffering effect can be maintained over a long period of time.

以下に本発明の具体的実施例を添付図に基づいて説明すると、図１〜図３において、１は複数本の設置用脚２を備えた筐体であり、この筐体１内に基台３が支持されている。当該基台３は、筐体１内の底部上に直接支持される第一基台４、この第一基台４上に複数本の支持柱体５を介して支持される第二基台６、及びこの第二基台６上に複数本の支持柱体７を介して支持される第三基台８から構成されている。９は第三基台８上に自在支持手段１０を介して支持された可動台であって、この可動台９上に複数本の支持柱体１１を介してレーザービーム投射器ユニット１２が支持されている。   A specific embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 denotes a housing having a plurality of installation legs 2. 3 is supported. The base 3 includes a first base 4 that is directly supported on the bottom of the housing 1, and a second base 6 that is supported on the first base 4 via a plurality of support pillars 5. And a third base 8 supported on the second base 6 via a plurality of support pillars 7. A movable base 9 is supported on the third base 8 via a universal support means 10. A laser beam projector unit 12 is supported on the movable base 9 via a plurality of support pillars 11. ing.

レーザービーム投射器ユニット１２は、本体１３の周囲に配設されて筐体１に設けられた投射窓からレーザービームを投射する垂直方向墨出し用レーザービーム投射器１４と水平方向墨出し用レーザービーム投射器１５とを備えたものであるが、何れか一方のレーザービーム投射器のみを備えたものであっても良い。又、一般的には、垂直方向墨出し用レーザービーム投射器１４と水平方向墨出し用レーザービーム投射器１５とをそれぞれ９０度間隔で４台ずつ配設することができる。   The laser beam projector unit 12 is disposed around the main body 13 and projects a laser beam from a projection window provided in the housing 1, and a vertical direction laser beam projector 14 and a horizontal direction laser beam. Although the projector 15 is provided, only one of the laser beam projectors may be provided. In general, four vertical inking laser beam projectors 14 and four horizontal inking laser beam projectors 15 can be arranged at intervals of 90 degrees.

可動台９を支持する自在支持手段１０は、第三基台８上に垂直に貫通するボルト１６によって据え付けられた球体１７と、この球体１７の上半部に嵌合するように可動台９の下側面に形成された円錐状凹部１８と、前記ボルト１６の上端部と可動台９の上面との間で当該ボルト１６に遊嵌されて可動台９を球体１７側へ押圧する円錐形のコイルスプリング（又はコーン形皿ばね）１９とから構成され、可動台９は、球体１７の中心１点を支点にして任意の方向に首振り運動可能に支持される。   The universal support means 10 for supporting the movable base 9 includes a sphere 17 installed by a bolt 16 penetrating vertically on the third base 8 and the movable base 9 so as to be fitted to the upper half of the sphere 17. A conical recess 18 formed on the lower surface, and a conical coil that is loosely fitted to the bolt 16 between the upper end of the bolt 16 and the upper surface of the movable base 9 and presses the movable base 9 toward the spherical body 17. The movable table 9 is supported by a single point of the center of the sphere 17 so that it can swing in any direction.

可動台９には姿勢検出用センサーである電子式水準器２０が取り付けられている。この図示例における電子式水準器２０は、一部が第三基台８を上下に貫通する複数本の支持柱体２１を介して第三基台８より下側で第二基台６を貫通する高さに吊り下げられている。而して、当該電子式水準器２０の検出情報に基づいて可動台９の姿勢を自動制御する２つの可動台姿勢制御装置２１Ａ，２１Ｂが併設されている。各可動台姿勢制御装置２１Ａ，２１Ｂは、図２に示すように、可動台９の揺動運動中心である球体１７の中心を通る垂直線に対し、互いに直角を成すＸＹ２方向に突出するように可動台９の２側面から突設された被動ピン２２Ａ，２２Ｂを介して可動台９をそれぞれ球体１７の中心を支点に上下方向に傾動させるものであって、第二基台６から突設された垂直板材２３に支持されている。   An electronic level 20 as an attitude detection sensor is attached to the movable table 9. The electronic level 20 in this illustrated example penetrates the second base 6 below the third base 8 through a plurality of support pillars 21 that partially penetrate the third base 8 up and down. It is hung to the height to be. Thus, two movable stand posture control devices 21A and 21B for automatically controlling the posture of the movable stand 9 based on the detection information of the electronic level 20 are provided. As shown in FIG. 2, each movable platform posture control device 21 </ b> A, 21 </ b> B projects in the XY2 direction perpendicular to each other with respect to a vertical line passing through the center of the sphere 17 that is the center of swinging motion of the movable platform 9. The movable table 9 is tilted in the vertical direction about the center of the sphere 17 via the driven pins 22A and 22B protruding from the two side surfaces of the movable table 9, and is projected from the second base 6. The vertical plate 23 is supported.

各可動台姿勢制御装置２１Ａ，２１Ｂは同一構造のもので、その具体構造について説明すると、それぞれ被動ピン２２Ａ，２２Ｂの先端部の横側方に位置するように、第二基台６側の垂直板材２３に取り付けられたコ形フレーム２４の上下両側板間に垂直向きに自転可能に支承された螺軸２５が設けられ、当該螺軸２５に螺嵌する昇降体２６に、水平横向きに突出して被動ピン２２Ａ，２２Ｂの先端部を上下から挟持する二股部２６ａが設けられている。２７は昇降体２６の回り止め昇降ガイドであって、コ形フレーム２４の垂直板部に取り付けられ、昇降体２６の横向き突出板部２６ｂが遊嵌する平面形状コ形のものである。螺軸２６は、コ形フレーム２４の下側板の下側に取り付けられたモーター２８と、当該下側板２４ｂの上側に配設された減速用歯車列２９を介して連動連結されている。従って、モーター２８により減速用歯車列２９を介して螺軸２５を正逆回転駆動することにより、昇降体２６を、その二股部２６ａが被動ピン２２Ａ，２２Ｂの先端部を挟持する向きを維持させながら昇降させることができる。   The movable base posture control devices 21A and 21B have the same structure. The specific structure will be described. The vertical positions on the second base 6 side so as to be located laterally of the distal ends of the driven pins 22A and 22B, respectively. A screw shaft 25 supported so as to be able to rotate in the vertical direction is provided between the upper and lower side plates of the U-shaped frame 24 attached to the plate member 23, and protrudes horizontally and horizontally on an elevating body 26 screwed into the screw shaft 25. A bifurcated portion 26a that clamps the tip ends of the driven pins 22A and 22B from above and below is provided. Reference numeral 27 denotes a detent raising / lowering guide for the elevating body 26, which is attached to the vertical plate portion of the U-shaped frame 24, and is a planar U shape in which the laterally protruding plate portion 26b of the elevating body 26 is loosely fitted. The screw shaft 26 is linked and connected via a motor 28 attached to the lower side of the lower plate of the U-shaped frame 24 and a reduction gear train 29 disposed on the upper side of the lower plate 24b. Therefore, by driving the screw shaft 25 forward and reversely through the reduction gear train 29 by the motor 28, the elevating body 26 is maintained in the direction in which the bifurcated portion 26a clamps the tip end portions of the driven pins 22A and 22B. Can be raised and lowered.

上記構成の墨出し装置は、設置用脚２を利用してほぼ水平な床面上に設置して使用するものであり、この設置状態において電子式水準器２０と各可動台姿勢制御装置２１Ａ，２１Ｂ、及び図示省略している制御回路などの電源を投入すると、電子式水準器２０が可動台９の水平度を自動的に検出し、この電子式水準器２０からの検出情報に基づいて可動台９の２次元平面のＸ方向の傾きとＹ方向の傾きが演算され、この演算結果に基づいて可動台姿勢制御装置２１Ａ，２１Ｂの両方又は何れか一方に対して駆動指令が出力され、この駆動指令を受けた可動台姿勢制御装置２１Ａ，２１Ｂは、モーター２８が稼働して螺軸２５が正転又は逆転駆動され、昇降体２６が所定量だけ上昇又は下降せしめられる。即ち、可動台９のＸ方向（被動ピン２２Ａの長さ方向）の傾きの矯正は、被動ピン２２Ａに対応した可動台姿勢制御装置２１Ａの昇降体２６を昇降させ、可動台９を球体１７の中心の周りに上方へ又は下方へ傾動させることにより行われ、可動台９のＹ方向（被動ピン２２Ｂの長さ方向）の傾きの矯正は、被動ピン２２Ｂに対応した可動台姿勢制御装置２１Ｂの昇降体２６を昇降させ、可動台９を球体１７の中心の周りに上方へ又は下方へ傾動させることにより行われる。   The ink marking device having the above-described configuration is used by being installed on a substantially horizontal floor using the installation legs 2, and in this installed state, the electronic level 20 and each movable stand posture control device 21A, When a power source such as 21B and a control circuit (not shown) is turned on, the electronic level 20 automatically detects the level of the movable base 9, and is movable based on the detection information from the electronic level 20. The tilt in the X direction and the tilt in the Y direction of the two-dimensional plane of the table 9 are calculated, and based on the calculation result, a drive command is output to both or one of the movable table attitude control devices 21A and 21B. In the movable platform posture control devices 21A and 21B that have received the drive command, the motor 28 is operated to drive the screw shaft 25 in the normal direction or the reverse direction, and the elevating body 26 is raised or lowered by a predetermined amount. That is, to correct the inclination of the movable base 9 in the X direction (the length direction of the driven pin 22A), the movable body 9 is moved up and down the movable body posture control device 21A corresponding to the driven pin 22A. The tilt of the movable base 9 in the Y direction (the length direction of the driven pin 22B) is corrected by tilting upward or downward around the center, and the correction of the tilt of the movable base posture control device 21B corresponding to the driven pin 22B is performed. The lifting / lowering body 26 is moved up and down, and the movable base 9 is tilted upward or downward around the center of the sphere 17.

尚、各被動ピン２２Ａ，２２Ｂに対して各可動台姿勢制御装置２１Ａ，２１Ｂの昇降体２６の二股部２６ａが、球体１７を中心とする周方向の同一向きで水平向きに嵌合しているだけであるから、当該被動ピン２２Ａ，２２Ｂが昇降体２６の二股部２６ａから離脱する方向に可動台９が球体１７を中心に水平方向に回転することができる。これを防止するために、図２に示すように、可動台９が球体１７を中心に水平方向に回転するのを防止する可動台回転防止手段３０を併設することができる。図示の可動台回転防止手段３０は、可動台９の側辺に形成した切込み凹部３１内に遊嵌するように第三基台８からストッパーピン３２を突設し、被動ピン２２Ａ，２２Ｂが昇降体２６の二股部２６ａから離脱する方向とは逆方向に可動台９を付勢するスプリング３３を併設し、このスプリング３３の付勢力でストッパーピン３２を切込み凹部３１の一側辺に当接させることにより、被動ピン２２Ａ，２２Ｂが昇降体２６の二股部２６ａ内の定位置に位置するように可動台９を保持させるものである。尚、スプリング３３は、基台３の任意の位置に付設した係止ピン３４と可動台９との間に張設される。   The bifurcated portion 26a of the lifting body 26 of each movable platform posture control device 21A, 21B is fitted horizontally to the driven pins 22A, 22B in the same circumferential direction around the sphere 17. Therefore, the movable base 9 can rotate in the horizontal direction around the sphere 17 in a direction in which the driven pins 22A and 22B are detached from the bifurcated portion 26a of the elevating body 26. In order to prevent this, as shown in FIG. 2, movable table rotation preventing means 30 for preventing the movable table 9 from rotating in the horizontal direction around the sphere 17 can be provided. The illustrated movable table rotation preventing means 30 has a stopper pin 32 protruding from the third base 8 so as to loosely fit into a cut recess 31 formed on the side of the movable table 9, and the driven pins 22A and 22B are moved up and down. A spring 33 that urges the movable base 9 in a direction opposite to a direction away from the bifurcated portion 26 a of the body 26 is provided, and the urging force of the spring 33 causes the stopper pin 32 to abut one side of the cut-out recess 31. Thus, the movable base 9 is held so that the driven pins 22A and 22B are located at fixed positions in the bifurcated portion 26a of the elevating body 26. The spring 33 is stretched between the locking pin 34 provided at an arbitrary position of the base 3 and the movable base 9.

上記のＸＹ２方向の可動台姿勢制御装置２１Ａ，２１Ｂの働きにより、可動台９上に支持されているレーザービーム投射器ユニット１２が、この墨出し装置の設置床面の傾きに関係なく所期通り水平に保持され、各レーザービーム投射器１４，１５による墨出し作業を高精度に行わせることができる。   The laser beam projector unit 12 supported on the movable table 9 can operate as expected regardless of the inclination of the installation floor surface of the marking device by the action of the movable table posture control devices 21A and 21B in the XY2 directions. It is held horizontally and the marking operation by the laser beam projectors 14 and 15 can be performed with high accuracy.

本発明は、以上のように構成され且つ使用されるる墨出し装置の被動ピン２２Ａ，２２Ｂに、少なくとも上下方向に弾性変位可能な緩衝作用部３５を設けるものである。図１、図２及び図４に示す実施形態では、前記被動ピン２２Ａ，２２Ｂは、昇降体２６の二股部２６ａに挟持される先端部材３６と可動台９への取付部材３７、及びこの両者３６，３７を連結するコイルスプリング３８から構成されている。更に詳述すると、先端部材３６と取付部材３７とには、その外周面にコイルスプリング３８の線材が嵌合する螺旋状の凹溝３６ａ，３７ａが設けられると共に、先端部材３６の内端からは、先端に係合孔３９が同心状に形成された小径突出軸部４０が一体に突設され、取付部材３７の内端からは、先端に前記係合孔３９に自動調心状態に嵌合する裁頭円錐形の凸部４１が同心状に突設された小径突出軸部４２が一体に突設されると共に、外端には可動台９のねじ孔に螺嵌結合される取付用ねじ軸部４３が突設されている。   In the present invention, a buffering action part 35 that is elastically displaceable at least in the vertical direction is provided on the driven pins 22A and 22B of the inking device configured and used as described above. In the embodiment shown in FIGS. 1, 2, and 4, the driven pins 22 </ b> A and 22 </ b> B include a tip member 36 sandwiched between the bifurcated portions 26 a of the elevating body 26, an attachment member 37 to the movable base 9, and both , 37 is connected to a coil spring 38. More specifically, the tip member 36 and the mounting member 37 are provided with spiral concave grooves 36a, 37a into which the wire rod of the coil spring 38 is fitted on the outer peripheral surface thereof, and from the inner end of the tip member 36. A small-diameter projecting shaft portion 40 having an engagement hole 39 concentrically formed at the tip is integrally projected, and the inner end of the mounting member 37 is fitted into the engagement hole 39 at the tip in a self-aligning state. A small-diameter projecting shaft portion 42 having a conical convex portion 41 projecting concentrically is integrally projected, and a mounting screw that is screwed into a screw hole of the movable base 9 at the outer end. A shaft portion 43 is projected.

而して、先端部材３６側の係合孔３９に取付部材３７側の凸部４１が嵌合した状態で先端部材３６側の小径突出軸部４０の端面と取付部材３７側の小径突出軸部４２の端面とが互いに面接触状態で当接したとき、先端部材３６と取付部材３７とが同心一直線状になり、そして両者が軸心に対し直交する方向に相対移動することは係合孔３９の開口部周縁と凸部４１と大径基部との当接により阻止されるように構成されている。そしてこの状態での先端部材３６の外端と取付部材３７の外端との間の距離よりも全長が短いコイルスプリング３８が使用されている。   Thus, the end surface of the small-diameter protruding shaft portion 40 on the tip member 36 side and the small-diameter protruding shaft portion on the attachment member 37 side in a state where the convex portion 41 on the mounting member 37 side is fitted in the engagement hole 39 on the tip member 36 side. When the end faces of 42 abut against each other in a surface contact state, the tip member 36 and the mounting member 37 are concentric and straight, and the relative movement of both in the direction perpendicular to the axis indicates that the engagement hole 39 It is comprised so that it may be blocked | prevented by contact | abutting with the peripheral part of an opening part, the convex part 41, and a large diameter base. In this state, a coil spring 38 having a shorter overall length than the distance between the outer end of the tip member 36 and the outer end of the mounting member 37 is used.

従って、コイルスプリング３８の一端側に先端部材３６の螺旋状凹溝３６ａが形成された部分の全長を螺嵌させた後、当該コイルスプリング３８の他端側に取付部材３７の螺旋状凹溝３７ａを螺嵌させてゆくと、当該コイルスプリング３８の長さ方向中間領域が弾性に抗して次第に軸方向に引き延ばされ、取付部材３７の螺旋状凹溝３７ａが形成された部分の全長がコイルスプリング３８に螺嵌し終わったとき、図４Ｂに示すように、コイルスプリング３８の長さ方向中間領域が弾性に抗して軸方向に引き延ばされた状態となり、当該コイルスプリング３８には、先端部材３６と取付部材３７とを互いに軸方向に圧接させる方向の初期圧縮応力が与えられた状態になる。これによって被動ピン２２Ａ，２２Ｂには必要な剛性を与えることができる。   Therefore, after the entire length of the portion where the spiral groove 36 a of the tip member 36 is formed on one end side of the coil spring 38 is screwed, the spiral groove 37 a of the mounting member 37 is connected to the other end side of the coil spring 38. When the screw is fitted, the intermediate region in the longitudinal direction of the coil spring 38 is gradually extended in the axial direction against elasticity, and the entire length of the portion of the mounting member 37 where the spiral groove 37a is formed is When the coil spring 38 has been screwed, as shown in FIG. 4B, the longitudinal intermediate region of the coil spring 38 is stretched in the axial direction against elasticity, and the coil spring 38 has In this state, an initial compressive stress is applied in a direction in which the tip member 36 and the attachment member 37 are pressed against each other in the axial direction. As a result, the required rigidity can be given to the driven pins 22A and 22B.

この実施形態では、コイルスプリング３８によって緩衝作用部３５が構成されており、可動台９の被動ピン２２Ａ，２２Ｂが取り付けられた箇所と昇降体２６との間にこれら両者を相対移動させるような外力が作用したとき、取付部材３７に対し先端部材３６がコイルスプリング３８の弾性変形を伴って首振り運動することになる。即ち、先端部材３６と取付部材３７との間にコイルスプリング３８の初期圧縮応力に打ち勝つ曲げ力が作用したときは、図４Ｃに示すように、コイルスプリング３８の長さ方向中間領域が初期圧縮応力に抗して曲げ変形を起こし、当該曲げ力に起因する衝撃を緩和させることができる。作用していた曲げ力が解消すると、コイルスプリング３８の初期圧縮応力によって先端部材３６と取付部材３７とは元の直線状態に復帰するが、このとき係合孔３９に対し裁頭円錐形の凸部４１が自動調心作用を伴いながら嵌合するので、先端部材３６と取付部材３７とは確実に同心一直線状に保持される。   In this embodiment, the buffering action part 35 is constituted by the coil spring 38, and an external force that relatively moves both of the movable base 9 between the place where the driven pins 22A and 22B are attached and the lift 26 is provided. When the is acted, the tip member 36 swings with the elastic deformation of the coil spring 38 with respect to the attachment member 37. That is, when a bending force that overcomes the initial compressive stress of the coil spring 38 is applied between the tip member 36 and the mounting member 37, the intermediate region in the longitudinal direction of the coil spring 38 has an initial compressive stress as shown in FIG. 4C. It is possible to reduce the impact caused by the bending force by causing bending deformation against the above. When the acting bending force is eliminated, the tip member 36 and the mounting member 37 are restored to the original linear state by the initial compressive stress of the coil spring 38. Since the portion 41 is fitted with an automatic aligning action, the tip member 36 and the attachment member 37 are reliably held concentrically and in a straight line.

又、図５に示す実施形態における被動ピン２２Ａ，２２Ｂは、先端部が昇降体２６の二股部２６ａに挟持されるピン本体４４と可動台９への取付部材４５、及び２本の弾性リング４６から構成されている。而して、取付部材４５には、ピン本体４４の基部側（昇降体２６の二股部２６ａに挟持される側とは反対側）が上下動可能に嵌合する下側開放の凹溝部４７が設けられ、この凹溝部４７に下から嵌合する状態のピン本体４４の基部と取付部材４５とにわたって前記弾性リング４６を外嵌させ、この弾性リング４６の弾性締結力で両者を一体化している。尚、取付部材４５には可動台９のねじ孔に螺嵌結合される取付用ねじ軸部４８が突設されている。又、弾性リング４６の位置を決めるために、ピン本体４４の基部と取付部材４５の円弧形外周面とには、軸心方向適当間隔を隔てて弾性リング４６の内周部が嵌合する凹溝４４ａ，４５ａを形成している。更に、取付部材４５に対してピン本体４４が弾性リング４６の弾性締結力に抗して上下方向に相対運動するとき、取付部材４５に対してピン本体４４が軸心方向外方へ移動するのを実質的に無くすために、ピン本体４４の内端面の中心が点接触する部分球面状突起４９を取付部材４５側に設けることができる。   Further, the driven pins 22A and 22B in the embodiment shown in FIG. 5 have a tip body 44 sandwiched by a bifurcated portion 26a of the elevating body 26, a mounting member 45 to the movable base 9, and two elastic rings 46. It is composed of Thus, the mounting member 45 has a lower open groove 47 in which the base side of the pin main body 44 (the side opposite to the side sandwiched between the bifurcated portions 26a of the elevating body 26) is movably fitted. The elastic ring 46 is externally fitted over the base portion of the pin main body 44 and the mounting member 45 in a state of being fitted to the concave groove portion 47 from below, and both are integrated by the elastic fastening force of the elastic ring 46. . The mounting member 45 is provided with a mounting screw shaft portion 48 that is screwed into the screw hole of the movable base 9. Further, in order to determine the position of the elastic ring 46, the inner peripheral portion of the elastic ring 46 is fitted to the base portion of the pin main body 44 and the arc-shaped outer peripheral surface of the mounting member 45 with an appropriate interval in the axial center direction. Concave grooves 44a and 45a are formed. Further, when the pin body 44 moves relative to the mounting member 45 in the vertical direction against the elastic fastening force of the elastic ring 46, the pin body 44 moves axially outward with respect to the mounting member 45. In order to substantially eliminate this, a partial spherical protrusion 49 with which the center of the inner end surface of the pin main body 44 makes point contact can be provided on the mounting member 45 side.

上記の図５に示す実施形態では、凹溝部４７に対して上下動可能に嵌合するピン本体４４の基部と弾性リング４６とによって緩衝作用部３５が構成されており、可動台９の被動ピン２２Ａ，２２Ｂが取り付けられた箇所と昇降体２６との間にこれら両者を上下方向に相対移動させるような外力が作用したとき、取付部材４５に対してピン本体４４が弾性リング４６の弾性締結力に抗して上下方向に相対運動することにより、当該外力に起因する衝撃を緩和させることができる。尚、弾性リング４６を２本使用した実施形態を示したが、その本数が限定されるものではなく、巾広の１本の弾性リングを使用して構成することもできる。   In the embodiment shown in FIG. 5 described above, the buffer action portion 35 is configured by the base portion of the pin main body 44 and the elastic ring 46 which are fitted to the concave groove portion 47 so as to be movable up and down, and the driven pin of the movable base 9 When an external force is applied between the position where 22A and 22B are attached and the lifting body 26 so as to move both of them vertically, the pin body 44 is elastically fastened to the attachment member 45 by the elastic ring 46. The impact caused by the external force can be mitigated by making a relative motion in the vertical direction against this. Although the embodiment using two elastic rings 46 has been shown, the number of the elastic rings 46 is not limited, and the elastic ring 46 may be configured by using one wide elastic ring.
