Abstract

PROBLEM TO BE SOLVED: To solve a problem of a conventional air cylinder which cannot be used to smoothly move between any intermediate stop, standby hold, and restart-up, and which requires a hydraulic cylinder or an air cylinder additionally having an external lock mechanism for any stops to a load fluctuation.SOLUTION: The present invention provides a minute-diameter pressure-reduction rectifier which provides a method for continuously applying load on an exhaust side of an air cylinder based on an idea of a hydraulic cylinder. In the embodiment, the control is only achieved by the air cylinder and the pressure-reduction rectifier without additionally providing an external device. The invention can implement a linear movement, and a movement intermediate stop, standby hold, and restart-up, regardless of change in 100% of load. Since an air pressure of a suction port and an exhaust port of the air cylinder is automatically balanced, the movement is implemented smoothly. While movement speed is decreased, a high level of pressure-reduction can provide various industries with an effect in the air-pressure cylinder.SELECTED DRAWING: Figure 3

図１は、本発明の小径０．４ｍｍの長さをもった多数の溝を有する減圧整流装置を示す。１はφ６で長さ１０ｍｍの円柱で、この円周に０．４ｍｍのＵ字溝ａを２０個配列したものである。 ２はφ１０長さ１０ｍｍの中心にφ６の穴のあるパイプ状のもので、この円周に０．４ｍｍのＵ字溝ａを４０個配列したものである。 この２の中央に１を嵌入して３を作る。 継ぎ手４は、５の５／８インチ雄ねじと６の５／８インチ雌ねじもち３０ｍｍの長さで中央に雌ねじ部を除きφ１０の穴をもつ一体加工されたものである。 この中央の雄ねじの部分に３を嵌入し６０孔の多数孔減圧整流装置７が完成する。  FIG. 1 shows a vacuum rectifying device having a large number of grooves with a small diameter of 0.4 mm according to the present invention. Reference numeral 1 denotes a cylinder having a diameter of 6 and a length of 10 mm, in which 20 0.4 mm U-shaped grooves a are arranged along the circumference. The reference numeral 2 denotes a pipe having a diameter of 10 mm and a length of 10 mm and a hole of φ6, and 40 U-shaped grooves a of 0.4 mm are arranged along the circumference. Insert 1 at the center of this 2 to make 3 The joint 4 is integrally processed with five 5/8 inch male screws and six 5/8 inch female screws 30 mm in length and a hole of φ10 except for the female screw portion in the center. 3 is inserted into the central male screw to complete a 60-hole multi-hole pressure reducing and rectifying device 7.

Reference numeral 8 denotes a cylinder having a diameter of 10 and a length of 10 mm, and has one hole b with a diameter of 0.4 at the center. The number 8 is inserted into the center male screw portion of the joint 4 to complete a one-hole small diameter pressure reducing and rectifying device 9.

図３は、下の移動台に固定されたシリンダ枠にシリンダ１９が固定され、シリンダロッド２０の上端に吊具台２９がレール台に吊してある。リニアレール２１を介しシリンダの移動により吊具台が上下移動できる装置である。
圧縮空気入口１０に０．６５Ｍｐａを接続する。 手動式切換弁１１を１２側へ切換、停止弁１４を通過しエアーシリンダ１９の２２へ供給される。シリンダの排気口２３から排気され、停止弁２８は閉じて図２の減圧整流装置２４と２６が復帰式押しボタンスイッチ切換弁２５及び２７により排気が開閉される。 シリンダ内部の空圧は排気側の２４及び２６の減圧整流装置図２により絶えずバランスした状態で１３から排気されるため、移動中は任意の点で手動式切換弁１１を停止するとエアーは閉じシリンダは瞬時停止し シリンダ内部の空気圧は自動的にバランスしている。然るに停止中は移動せず保持され、再始動時もスムーズに移動する。 １１を１３側へ切換逆移動をする場合は、上記と対称の回路により排気側１４，１５，１６、１７，１８が上述と同様に排気側の減圧整流装置が動作する。
復帰式押しボタン切換弁１６と１８、は図２の減圧整流装置１５と１７を開閉し、又、復帰式押しボタン切換弁２５と２７は減圧整流装置図２の２４と２６を開閉して、２回路を各並列に利用した排気時の排気量を調節するもので、ボタンの押し方で速度を変えるものである。In FIG. 3, the cylinder 19 is fixed to a cylinder frame fixed to the lower moving table, and a hanger table 29 is suspended from the rail table at the upper end of the cylinder rod 20. This is a device capable of vertically moving the stand by moving the cylinder via the linear rail 21.
Connect 0.65 MPa to the compressed air inlet 10. The manual switching valve 11 is switched to the 12 side, passes the stop valve 14, and is supplied to the air cylinder 22. The exhaust valve 23 is exhausted from the exhaust port 23 of the cylinder, the stop valve 28 is closed, and the depressurizing and rectifying devices 24 and 26 of FIG. Since the air pressure inside the cylinder is exhausted from 13 while being constantly balanced according to Fig. 2 on the exhaust side 24 and 26, if the manual switching valve 11 is stopped at any point during movement, the air closes the cylinder The air pressure inside the cylinder is automatically balanced. While it is stopped, it is held without moving, and it moves smoothly when restarting. In the case of switching 11 to the 13 side, the exhaust side 14, 15, 16, 17, 18 operates in the same manner as described above by the circuit symmetrical with the above, and the pressure reducing rectifier on the exhaust side operates.
The return type push button switching valves 16 and 18 open and close the pressure reducing and rectifying devices 15 and 17 of FIG. 2, and the return type push button switching valves 25 and 27 open and close 24 and 26 of the pressure reducing rectifying device FIG. Two circuits are used in parallel to adjust the displacement at the time of exhausting, and the speed is changed by pushing the button.

図４は、荷重変化を伴う介護用トイレの収納形態図を示す。
圧縮空気入口４４に０．６５Ｍｐａを接続する。 手動式切換弁３７を３８側へ切換、停止弁３９を通過しエアーシリンダ３０の３５へ供給される。シリンダの排気口３６から排気され、逆止弁４３は閉じて図２の減圧整流装置４２で減圧され４１から排気される。 シリンダ内部の空気圧は排気側の減圧効果で吸入口と排気口の空気圧が自動的にバランスした状態で排気されるため、加重が最大から最小まで１００％変化しても手動式切換弁３７を閉じれば瞬時に停止し、停止時間３０分まで保持される。 再始動時もスムーズに移動する。
手動式切換弁３７を４１側へ切換、エアーは逆止弁４３を通過しシリンダ３６に供給され排気側逆止弁３９は閉じ、図２の減圧整流装置４０で減圧されシリンダの空気圧はバランスしながら排気される。 荷重最小から最大まで変化してもエアーシリンダの吸入口と排気口の空気圧が自動的にバランスするので荷重が変化しても中間停止は可能である。FIG. 4 shows a storage form diagram of a care toilet accompanied by a load change.
Connect 0.65 MPa to the compressed air inlet 44. The manual switching valve 37 is switched to the 38 side, passes the stop valve 39, and is supplied to the air cylinder 35 35. The air is exhausted from the exhaust port 36 of the cylinder, the check valve 43 is closed, and the pressure is reduced by the pressure reduction and rectification device 42 of FIG. The air pressure inside the cylinder is exhausted with the air pressure at the suction port and exhaust port automatically balanced due to the pressure reduction effect on the exhaust side, so the manual switching valve 37 is closed even if the load changes 100% from the maximum to the minimum Stop immediately and hold for up to 30 minutes. It moves smoothly even at restart.
The manual switching valve 37 is switched to the 41 side, air passes through the check valve 43 and is supplied to the cylinder 36, the exhaust side check valve 39 is closed, the pressure is reduced by the pressure reducing and rectifying device 40 of FIG. While being exhausted. Even if the load changes from the minimum to the maximum, the air pressure at the inlet and exhaust of the air cylinder is automatically balanced, so an intermediate stop is possible even if the load changes.

図５は、図１の多数溝減圧整流装置を用いチェック式絞り弁と併用した回路であり、４７と５３の減圧整流装置をエアーシリンダの吸入側と排出側の両端で減圧効果を得る方法で、この効果は、エアー５５を４５の手動切換弁で５４側へ切換えたときのスタート時にチェック弁５２が開いたときのエアー流速を５３の減圧整流装置により遅くし、その時の衝撃を吸収しスムーズな移動が得られる。さらに排気側の絞り弁４８を通過したエアーは更に減圧整流装置４７で減圧されるので絞り弁４８の調節が非常に容易になる。これは直線移動又は可変荷重にも圧縮空気圧安定装置として動作し使いやすさの効果は上がる。  FIG. 5 shows a circuit in which the multiple groove pressure reducing and rectifying device of FIG. 1 is used in combination with a check type throttle valve, and the pressure reducing and rectifying devices 47 and 53 are reduced in pressure on both the suction side and the discharge side of the air cylinder. This effect slows down the air flow velocity when the check valve 52 is opened at the start when the air 55 is switched to the 54 side with the manual switching valve 45. By the 53 pressure reduction and rectification device, the impact is absorbed and smoothed. Movement is obtained. Further, the air having passed through the exhaust side throttle valve 48 is further depressurized by the pressure reducing and rectifying device 47, so that the adjustment of the throttle valve 48 becomes very easy. This works as a compressed air pressure stabilizer even for linear movement or variable loads, and the usability is enhanced.

手動式切換弁３７を４１側へ切換、エアーは逆止弁４３を通過しシリンダ３６に供給され排気側逆止弁３９は閉じ、図２の圧縮空気圧安定装置４０で安定されシリンダの空気圧はバランスしながら排気される。 荷重最小から最大まで変化してもエアーシリンダの吸入口と排気口の空気圧が自動的にバランスするので荷重が変化しても中間停止は可能である。FIG. 4 shows a storage form diagram of a care toilet accompanied by a load change.
Connect 0.65 MPa to the compressed air inlet 44. The manual switching valve 37 is switched to the 38 side, passes the stop valve 39, and is supplied to the air cylinder 35 35. The air is exhausted from the exhaust port 36 of the cylinder, the check valve 43 is closed and stabilized by the compressed air pressure stabilization device 42 of FIG. Since the air pressure inside the cylinder is exhausted with the air pressure at the suction port and exhaust port automatically balanced by the exhaust side stabilizer , the manual switching valve 37 is closed even if the load changes 100% from the maximum to the minimum Stop immediately and hold for up to 30 minutes. It moves smoothly even at restart.
The manual switching valve 37 is switched to the 41 side, the air passes through the check valve 43 and is supplied to the cylinder 36, the exhaust check valve 39 is closed, and stabilized by the compressed air pressure stabilizer 40 of FIG. While being exhausted.

図５は、図１の多数溝圧縮空気圧安定装置を用いチェック式絞り弁と併用した回路であり、４７と５３の圧縮空気圧安定装置をエアーシリンダの吸入側と排出側の両端で安定効果を得る方法で、この効果は、エアー５５を４５の手動切換弁で５４側へ切換えたときのスタート時にチェック弁５２が開いたときのエアー流速を５３の圧縮空気圧安定装置により遅くし、その時の衝撃を吸収しスムーズな移動が得られる。さらに排気側の絞り弁４８を通過したエアーは更に圧縮空気圧安定装置４７で安定されるので絞り弁４８の調節が非常に容易になる。これは直線移動又は可変荷重にも圧縮空気圧安定装置として動作し使いやすさの効果は上がる。Figure 5 is a circuit in combination with the check type throttle valve using a number grooves compressed air stabilizer of Figure 1, to obtain a stabilizing effect 47 and 53 the compressed air pressure stabilizing device with the suction side of the air cylinder at both ends of the discharge side In this way, this effect slows down the air flow velocity when the check valve 52 opens at the start when switching the air 55 to the 54 side with the 45 manual switching valve, by means of the 53 compressed air pressure stabilizer , and the impact at that time Absorbs and moves smoothly. Furthermore, since the air that has passed through the exhaust side throttle valve 48 is further stabilized by the compressed air pressure stabilization device 47, the adjustment of the throttle valve 48 becomes very easy. This works as a compressed air pressure stabilizer even for linear movement or variable loads, and the usability is enhanced.
