Description
【０００１】[0001]
本考案は、各種の加工機やロボット等のハンドリングツールとして或いはその 他の保持具用途一般に利用可能な吸盤装置に関するものである。 The present invention relates to a suction cup device that can be generally used as a handling tool for various types of processing machines and robots, or for other holding tool applications.
【０００２】[0002]
従前の圧着式吸盤の問題点として、吸着保持力の調整が行えないため、所要の 吸着荷重に耐える必要十分な保持力のものを使用した場合、吸着面から引き離す のに過大な引離し力が必要となって、取外し作業に難渋することがある。 The problem with the conventional crimp suction cups is that the suction holding force cannot be adjusted.Therefore, if a holding force that is necessary and sufficient to withstand the required suction load is used, an excessive pulling force is required to pull it away from the suction surface. It may become difficult and difficult to remove.
【０００３】 このため、吸着保持力の自在調整と瞬時の取外しが要求される各種のハンドリ ングツールの用途には、一般にバキュームパッドが使用されているが、この場合 には真空ポンプや電磁切換弁等の付帯設備が必要となり、設備が高価につく問題 が指摘される。For this reason, a vacuum pad is generally used for various handing tools that are required to freely adjust the suction holding force and be removed instantaneously. In this case, a vacuum pump or an electromagnetic switching valve is used. It is pointed out that there is a need for additional equipment such as equipment, which makes the equipment expensive.
【０００４】 本考案は、かかる現状の問題点に鑑みて、吸着保持力の調整が自在に行え取外 し容易なものに改良された圧着式の吸盤装置を提供している。In view of the above-mentioned problems of the present invention, the present invention provides an improved crimp-type suction cup device in which the suction holding force can be freely adjusted and easily removed.

本考案に係る吸盤装置では、吸盤本体の軸心部に開放弁をスライド可能に貫挿 し、吸盤本体と開放弁の上端部に螺合されたアジャスタナットとにスプリングを 介入して、開放弁の下端部に設けた弁体を吸盤本体の内面から環状に突設させた 弁座部に圧着させると共に、上記弁体で気密に封鎖される弁座部内側の弁座部内 室を大気と連通させるようにしたものからなっている。 In the suction cup device according to the present invention, the opening valve is slidably inserted into the axial center portion of the suction cup body, and the spring is interposed between the suction cup body and the adjuster nut screwed to the upper end portion of the opening valve to open the opening valve. The valve body provided at the lower end of the valve seat is crimped to the valve seat part that is projected from the inner surface of the suction cup body in an annular shape, and the valve seat inner chamber inside the valve seat part that is hermetically sealed by the valve body communicates with the atmosphere. It is made to let you.
【０００６】[0006]
このように構成した吸盤装置では、吸着状態から吸盤本体を引き離そうとする と、本体内の弁体には、その引離し力と釣り合う吸盤本体内の負圧が弁体に及ぼ す弁体吸引力と、スプリングから付与される弁体閉止力とが作用し、負圧による 弁体吸引力がスプリングによる弁体閉止力に打ち勝ったとき、弁体が弁座部から クラックして弁座部内室から吸盤本体内に大気圧が導入され、瞬時に取外し可能 となる。すなわち、開放弁の上端部に螺合されたアジャスタナットの位置を変え てスプリング力を調整することにより、吸盤本体の吸着保持力を自在に調整する ことができる。 In the suction cup device configured in this way, when trying to separate the suction cup body from the suctioned state, the negative pressure inside the suction cup body that balances the separation force exerts on the valve body suction force. When the valve body closing force given by the spring acts and the valve body suction force due to the negative pressure overcomes the valve body closing force of the spring, the valve body cracks from the valve seat portion and the valve seat inner chamber Atmospheric pressure is introduced into the suction cup body, and it can be removed instantly. That is, the suction holding force of the suction cup body can be freely adjusted by changing the position of the adjuster nut screwed to the upper end of the release valve to adjust the spring force.
【０００７】[0007]
図１は、上述した本考案に係る吸盤装置の実施例を図示している。 FIG. 1 illustrates an embodiment of the suction cup device according to the present invention described above.
【０００８】 吸盤本体１は、基盤部２とスカート部３とを具備してなり、少なくともスカー ト部３は可撓性に有する樹脂材料で一体成形されている。ちなみに、図示例の場 合には、吸盤本体１は別部材Ａ、Ｂを組み立てた組立品で構成されている。The suction cup body 1 includes a base portion 2 and a skirt portion 3, and at least the scart portion 3 is integrally formed of a flexible resin material. Incidentally, in the case of the illustrated example, the suction cup body 1 is composed of an assembly product in which separate members A and B are assembled.
【０００９】 吸盤本体１の基盤部２には、軸心部に貫通穴４が設けられ、この貫通穴４に棒 状の開放弁５が上下にスライド可能に貫挿されている。開放弁５には、吸盤本体 １に内挿される下端部に円盤状の弁体６が設けられていると共に、上端に押釦部 ７が設けられる上端部の外周にはねじ部８が刻設され、このねじ部８にアジャス タナット９が上下方向で螺進退自在に螺合されている。A through hole 4 is provided in a shaft center portion of the base portion 2 of the suction cup body 1, and a rod-shaped open valve 5 is vertically slidably inserted into the through hole 4. The open valve 5 is provided with a disc-shaped valve body 6 at a lower end portion which is inserted into the suction cup body 1, and a screw portion 8 is engraved on an outer periphery of an upper end portion where a push button portion 7 is provided at an upper end. An adjuster nut 9 is screwed onto the screw portion 8 so as to be able to move forward and backward in the vertical direction.
【００１０】 開放弁５の周りには、本体基盤部２の上面と対向するアジャスタナット９の下 面との間にコイルスプリング１０を介入して、開放弁５の下端部に設けられてい る上記弁体６を、本体基盤部２の内面から環状に突設させた弁座部１１にスプリ ング１０の調節されたスプリング力で圧着させるようにしている。なお、本体基 盤部２の内面から突設される環状の弁座部１１は、潰れ変形し易い断面形状に形 成されていると共に、図示例の場合には、スカート部３と同材の可撓性に富む部 材Ｂで成形され、弁体６の圧着部で気密性を保つパッキン効果を得るようにして いる。A coil spring 10 is interposed around the open valve 5 between the upper surface of the main body base portion 2 and the lower surface of the adjuster nut 9 which faces the open valve 5, and is provided at the lower end portion of the open valve 5. The valve body 6 is crimped onto the valve seat portion 11 which is provided in an annular shape from the inner surface of the main body base portion 2 by the spring force of the spring 10 adjusted. In addition, the annular valve seat portion 11 provided so as to project from the inner surface of the main body base portion 2 is formed in a cross-sectional shape that is easily crushed and deformed, and in the case of the illustrated example, the same material as the skirt portion 3 is used. It is made of a material B having high flexibility, and a packing effect for maintaining airtightness is obtained at the crimping portion of the valve body 6.
【００１１】 そして、本体基盤部２の軸心部には、その内外面を貫通するエア通路１２が穿 設され、上記弁体６で気密に封鎖される弁座部１１内側の弁座部内室１３を大気 と連通させるようにしている。An air passage 12 penetrating the inner and outer surfaces of the main body base portion 2 is bored in the axial center portion of the main body base portion 2, and the valve seat portion inner chamber inside the valve seat portion 11 is hermetically sealed by the valve body 6. 13 is in communication with the atmosphere.
【００１２】 上記の如く構成された吸盤装置であれば、開放弁５の上端部に螺合されたアジ ャスタナット９の位置を変えてスプリング長を調節し、スプリング力の強さを調 整することにより、吸盤本体１の吸着保持力を自在に調整することができるもの となる。With the suction cup device configured as described above, the spring length is adjusted by changing the position of the adjuster nut 9 screwed to the upper end of the release valve 5 to adjust the strength of the spring force. As a result, the suction holding force of the suction cup body 1 can be freely adjusted.
【００１３】 図２は、ワークＷの表面にスカート部３の開口端を拡開変形させるように押し 付けて圧着させた吸着状態から、例えばワークＷの両側にストッパ１４、１４を 掛止させて、吸盤本体１をワークＷの吸着面から強制的に引き離そうとする際の 作用を図示している。FIG. 2 shows the state in which the open end of the skirt portion 3 is pressed against the surface of the work W so as to be expanded and deformed, and the work piece W is adsorbed to the surface thereof. , The action when forcibly separating the suction cup body 1 from the suction surface of the work W is illustrated.
【００１４】 今、吸盤本体１に引離し力Ｆが作用して、吸盤本体１がワークＷから引き離さ れる寸前の段階を想定すると、この状態では、その引離し力Ｆと、吸盤本体１の 内部に発生している負圧Ｐｘによる吸着力｛＝（Ｐｏ−Ｐｘ）・Ｓｘ｝とが釣り 合いを保っている。そして、このとき本体１内の弁体６には、負圧Ｐｘが弁体６ に及ぼす下向きの弁体吸引力ｆｘ｛＝（Ｐｏ−Ｐｘ）・Ｓｖ｝と、スプリング１ ０から付与される上向きの弁体閉止力ｆｓとが作用し、スプリング１０による弁 体閉止力ｆｓが未だ優勢（ｆｓ＞ｆｘ）を保っている。Now, assuming a stage just before the suction force F is applied to the suction cup body 1 to separate the suction cup body 1 from the work W, in this state, the separation force F and the inside of the suction cup body 1 The suction force {= (Po-Px) · Sx} due to the negative pressure Px generated in the equilibrium is maintained. Then, at this time, the valve body 6 in the main body 1 has a downward valve body suction force fx {= (Po-Px) · Sv} exerted by the negative pressure Px on the valve body 6 and an upward direction given from the spring 10. The valve closing force fs and the valve closing force fs by the spring 10 still maintain the superiority (fs> fx).
【００１５】 この状態から、吸盤本体１に加わる引離し力Ｆが更に増強された場合を考える と、このときには吸盤本体１は増強された引離し力によってより一層上向きに引 っ張られる結果、内空容積が増して吸盤本体１内での負圧Ｐｘも増大されること になる。そして、吸盤本体１内で発生される負圧Ｐｘがある臨界値にまで到達す ると、弁体吸引力ｆｘが弁体閉止力ｆｓに打ち勝ち（ｆｘ≧ｆｓ）、弁体６が弁 座部１１からクラックして、弁座部内室１３から吸盤本体１内に図示点線矢印で 示すように大気圧Ｐｏが導入され、この状態で瞬時に取外し可能となる。Considering the case where the separation force F applied to the suction cup body 1 is further increased from this state, at this time, the suction cup body 1 is pulled further upward by the increased separation force, and as a result, The empty volume increases and the negative pressure Px in the suction cup body 1 also increases. When the negative pressure Px generated in the suction cup body 1 reaches a certain critical value, the valve body suction force fx overcomes the valve body closing force fs (fx ≧ fs), and the valve body 6 moves to the valve seat portion. After cracking from 11, the atmospheric pressure Po is introduced from the valve seat inner chamber 13 into the suction cup body 1 as shown by the dotted arrow in the drawing, and in this state, the atmospheric pressure Po can be instantly removed.
【００１６】 このように、本吸盤装置においては、開放弁５の弁体６に弁体閉止力ｆｓを及 ぼしているスプリング１０のスプリング力の強さが、弁体６を自動開放する負圧 Ｐｘの臨界値、言い換えると、吸盤本体１の吸着力の大きさを支配するものとな る。従って、開放弁５の上端部に螺合されたアジャスタナット９の位置を変えて スプリング力を調整すれば、吸盤本体１の吸着保持力を自在に調整することがで きる。そして、吸着保持力が可変できれば、ワークＷの荷重に対してその吸着保 持力を若干大きく設定することにより、取外しの際に必要な引離し力Ｆを軽微な ものにすることができる。As described above, in the present suction cup device, the strength of the spring force of the spring 10 exerting the valve body closing force fs on the valve body 6 of the opening valve 5 causes the negative force to automatically open the valve body 6. The critical value of the pressure Px, in other words, controls the magnitude of the suction force of the suction cup body 1. Therefore, if the spring force is adjusted by changing the position of the adjuster nut 9 screwed to the upper end of the opening valve 5, the suction holding force of the suction cup body 1 can be adjusted freely. If the suction holding force can be varied, the pulling force F required for detachment can be made small by setting the suction holding force to be slightly larger than the load of the work W.
【００１７】 また、この吸盤装置のもう一つの特長としては、開放弁５の上端に設けられて いる押釦部７を押し下げるようにすると、弁体６が弁座部１１から強制的に開離 されて、前記と同様に吸盤本体１内に大気圧Ｐｏが即時に導入され、吸着保持力 の設定値と無関係に吸盤本体１を瞬時に取外し操作できることが挙げられる。Another feature of the suction cup device is that when the push button portion 7 provided at the upper end of the release valve 5 is pushed down, the valve body 6 is forcibly opened from the valve seat portion 11. As described above, the atmospheric pressure Po is immediately introduced into the suction cup body 1 so that the suction cup body 1 can be instantly removed and operated regardless of the set value of the suction holding force.
【００１８】[0018]
以上に詳述した通り、本考案の新型吸盤装置であれば、吸盤本体の吸着保持力 が開放弁に螺合されたナット操作によって自在に調整でき、加えて必要な場合は 開放弁の押下げ動作により吸着保持力の如何によらず瞬時に取り外しすることが できる。従って、吸着保持力の調整が要求される各種ハンドリングツールの用途 には、構造簡単で付帯設備を要しないバキュームパッド代替品としての実用価値 を有するものとなる。また、保持具一般用途に対しても、保持力の可変性と取扱 操作の簡便性とにより、すこぶる便利なものとなり得る。 As described in detail above, with the new suction cup device of the present invention, the suction holding force of the suction cup body can be freely adjusted by operating the nut screwed into the release valve, and in addition, the release valve can be pushed down if necessary. By the operation, it can be removed instantly regardless of the suction holding force. Therefore, it has a practical value as a substitute for a vacuum pad that has a simple structure and does not require any auxiliary equipment for the use of various handling tools that require adjustment of suction holding force. Further, even for general use of the holder, it can be extremely convenient because of the variability of the holding force and the easiness of handling operation.
