Description
본 발명은 오일이나 접착제 및 약품과 같은 액체의 정량토출을 위한 펌프에 관한 것으로서, 특히 스풀의 동작으로 단일 통로를 개폐시켜 액체의 충진과 토출이 이루어지게 하며, 동시에 액체의 토출량 조절이 가능토록 한 것이다.The present invention relates to a pump for quantitative discharging of liquids such as oils, adhesives, and chemicals, and in particular, to open and close a single passage by the operation of a spool to fill and discharge liquids, and at the same time to control the discharge amount of liquids. will be.
오일이나 접착제, 약품과 같은 액체의 정량토출을 위한 밸브에 관하여서는 본 발명자가 여러구성의 제품들을 선출원하여 등록된 것이있다.Regarding the valve for quantitative discharging of a liquid such as an oil, an adhesive, or a medicine, the inventors have previously registered and registered products of various configurations.
한예로서 실용신안등록 제341031호로 등록한 정량토출밸브가 있다.As an example, there is a fixed-quantity discharge valve registered under Utility Model Registration No. 341031.
즉 정량토출밸브를 구성함에 있어서, 계량실 본체내에 구성된 계량실에 액체피스톤을 승강가능케 결합구성하되, 후방에 구성된 피스톤봉이 밸브캡에 끼워진 조정봉과 접하게 하여 계량실내의 체적이 조정되게 하고, 상기 계량실 상하부에는 상부출입공과 하부출입공을 구성하고, 계량실본체 전면에는 에어피스톤이 승강가능케 끼워진 작동실을 구성하고, 상기 작동실 상하부에는 상부관통공과 하부관통공을 구성하고, 작동실 전면에는 스풀을 지지하는 스풀지지체와 작동체를 구성하되, 그 사이에 공급공과 확장공 및 하출입공을 구성하고, 작동체에는 통로와 상출입공을 구성하고, 상기 상출입공과 하출입공을 상부출입공과 연결되게 하고, 작동체 전면에는 통로와 상통하는 토출공을 구성하고, 작동체에 구성된 통로와 전면에 구성된 토출공에는 스풀이 끼워져 구성되게 하되 스풀에 구성된 요입부가 통로상에 위치되게 하고 상부봉체는 토출공에 끼워져 구성되게 하므로서 스풀의 승강작동에 의해 계량실내에 액체가 주입되고, 토출되게 한 것이다.That is, in the quantitative discharge valve, the liquid piston can be lifted and coupled to the weighing chamber configured in the weighing chamber main body, and the piston rod configured at the rear side is in contact with the adjusting rod fitted to the valve cap to adjust the volume in the weighing chamber. The upper entrance hole and the lower entrance hole are configured, and the operating chamber in which the air piston is lifted up and down is mounted on the front of the metering chamber main body, and the upper and lower through holes are formed on the upper and lower parts of the operating chamber, and the spool is supported on the front of the operating chamber. Comprising a support body and the actuator, between the supply hole and expansion hole and the lower entry hole, the actuator constitutes the passage and the upper entry hole, the upper entry hole and the lower entry hole to be connected to the upper entry hole, The discharge hole is formed in the front surface of the actuator and is in communication with the passage. But configured to be inserted into the pool it will be one to be placed on the concave portion to the spool passage configured and upper bongche is by the lifting operation of the spool configured to be inserted into the discharge hole hameuroseo the liquid is injected into the metering room, discharge.
따라서 액체를 토출하고자 할 때 스풀의 승강작동에 의해 상하부 출입공으로 주입되는 액체의 위치를 조정하여 계량실내에 끼워진 액체피스톤이 승강하면서 계량실내에 채워진 액체가 토출공을 통하여 토출되게 하되 필요한 경우 뒷쪽에 구성된 조정봉을 이용하여 액체의 토출완료후에는 스풀이 후진하면서 토출공전면에 잔류하는 액체를 흡입시켜 드립현상을 방지케 하는 등의 효과가 있는 것이나 계량실내에 액체를 충진하거나 충진된 액체를 토출하기 위한 수단으로서 항상 일정한 압력으로 유지되는 액체의 자체압력에 의해 이루어지게 한 것으로서 별도의 가압수단을 구비하여야 하게 될 뿐 아니라 액체의 출입통로가 대체로 길고 복잡하게 구성되어 있는 등의 단점도 있는 것이었다.Therefore, when the liquid is to be discharged, the liquid injected into the upper and lower entrance holes is adjusted by the lifting operation of the spool so that the liquid piston inserted in the weighing chamber is lifted and the liquid filled in the weighing chamber is discharged through the discharge hole. After discharging the liquid using the configured adjusting rod, the spool moves backward and sucks the liquid remaining on the discharge cavity surface to prevent drip phenomenon.However, it is necessary to fill the liquid in the measuring chamber or discharge the filled liquid.

이와같이 구성된 본 발명의 정량토출펌프(100)의 작동은 다음과 같이 이루어지게 된다.Operation of the quantitative discharge pump 100 of the present invention configured as described above is made as follows.
먼저 액체(440)의 충진은 다음과 같이 된다.First, the filling of the liquid 440 is as follows.
즉 도 5에서와 같이 계량피스톤(220)이 최전진하고, 실린더(500)에 끼워진 피스톤(520)이 전진하여 스풀(530)의 요입부(532)가 제2통로(422)에 위치된 상태에서 계량실(410)내에 액체(440)를 충진하고자 할 경우에는 먼저 스풀(530)을 이동시켜 제2통로(422)를 밀폐시켜야 한다.That is, as shown in FIG. 5, the metering piston 220 moves forward, the piston 520 fitted to the cylinder 500 moves forward, and the recess 532 of the spool 530 is positioned in the second passage 422. In the case where the liquid 440 is to be filled in the metering chamber 410, first, the spool 530 must be moved to seal the second passage 422.
따라서 도 6에서와 같이 실린더(500)에 구성된 하주입공(512)으로 공기를 주입하여 작동실(510)내에 끼워진 피스톤(520)을 상승시켜 이와 연결된 스풀(530)을 윗쪽으로 이동시켜 스풀(530)의 머리부(533)가 제2통로(422)에 위치하여 밀폐되게 하고, 요입부(532)가 제1통로(421)에 위치하여 개방되게 하므로 제1통로(421)와 제3통로(423)를 통하여 유입공(420)과 계량실(410)이 상통하게 한다.Therefore, as shown in FIG. 6, air is injected into the lower injection hole 512 configured in the cylinder 500 to raise the piston 520 fitted in the operation chamber 510 to move the spool 530 connected thereto to the spool 530. The head portion 533 is positioned in the second passage 422 to be sealed, and the concave inlet portion 532 is positioned in the first passage 421 to be opened so that the first passage 421 and the third passage ( The inlet hole 420 and the metering chamber 410 communicate with each other through 423.
상기 한 상태에서 에어실린더(300)에 구성된 하유입공(312)을 통하여 압축공기가 작동실(310)내에 유입되게 하면 작동실(310)내에 끼워진 에어피스톤(320)이 후진하에 되고, 따라서 피스톤로드(221)로 연결된 계량피스톤(220)이 서서히 후진하게 되므로 액체(440)는 계량피스톤(220)의 흡입력에 의해 제1통로(421)와 제3통로(423)를 통하여 계량실(410)내에 충진된다.When the compressed air is introduced into the operation chamber 310 through the inlet hole 312 configured in the air cylinder 300 in the above state, the air piston 320 inserted in the operation chamber 310 is reversed, and thus the piston Since the metering piston 220 connected to the rod 221 is gradually reversed, the liquid 440 is in the metering chamber 410 through the first passage 421 and the third passage 423 by the suction force of the metering piston 220. It is filled.
계량실(410)내에 액체(440)의 충진이 완료되면 도 7에서와 같이 위치되어 충진완료와 동시에 토출대기상태가 된다.When the filling of the liquid 440 in the metering chamber 410 is completed, it is positioned as shown in FIG. 7 and is in the discharge standby state at the same time as the filling is completed.
도 7에서와 같은 상태에서 계량실(410)내에 충진된 액체(440)를 토출하고자 할 경우에는 도 8에서와 같이 스풀(530)을 하강시켜 제1통로(421)는 패쇄되게 함과 동시에 제2통로 (422)는 개방시켜야 한다.When discharging the liquid 440 filled in the metering chamber 410 in the same state as in FIG. 7, the first passage 421 is closed and the second passage 421 is closed by lowering the spool 530 as shown in FIG. 8. The passage 422 must be open.
즉 실린더(500)에 구성된 상주입공(511)으로 압축공기를 주입하면 작동실(510)내에 끼워진 피스톤(520)이 하강하게 되고, 동시에 이와 연결된 스풀(530)도 하강하게 된다.That is, when compressed air is injected into the upper injection hole 511 configured in the cylinder 500, the piston 520 fitted into the operation chamber 510 is lowered, and at the same time, the spool 530 connected thereto is lowered.
상기에서와 같이 스풀(530)이 하강하게 되면 스풀(530) 본체(531)가 제1통로(421)를 밀폐하여 패쇄시키게 되고, 동시에 요입부(532)가 제2통로(422)에 위치하면서 개방상태를 유지하게 된다.As described above, when the spool 530 is lowered, the spool 530 main body 531 seals and seals the first passage 421. At the same time, the recess 532 is positioned in the second passage 422. Will remain open.
상기한 상태에서 에어실린더(300)에 구성된 상유입공(311)을 통하여 압축공기가 작동실(310)내에 유입되게 하면 압축공기에 의해 에어피스톤(320)이 서서히 전진하게 되고 따라서 피스톤로드(221)로 연결된 계량피스톤(220)이 전진하면서 계량실(410)내에 채워진 액체(440)를 제3통로(423)와 제2통로(422) 및 토출공(424)을 통하여 전방으로 토출이 이루어지게 된다.When the compressed air is introduced into the operation chamber 310 through the upper inlet hole 311 configured in the air cylinder 300 in the above state, the air piston 320 is gradually advanced by the compressed air, and thus the piston rod 221. As the metering piston 220 connected to the pump is advanced, the liquid 440 filled in the metering chamber 410 is discharged forward through the third passage 423, the second passage 422, and the discharge hole 424. .
상기에서와 같이 하여 계량실(410)내에 충진된 액체(440)의 토출이 완료되면 위에서 설명한바와 같은 동작의 반복으로 계량실(410)내에 액체를 충진하고 토출하는 동작을 반복하게 된다.When the discharge of the liquid 440 filled in the metering chamber 410 is completed as described above, the operation of filling and discharging the liquid in the metering chamber 410 is repeated by repeating the operation as described above.
상기 본 발명의 정량토출펌프(100)를 구성함에 있어서, 토출되는 액체(440)의 토출량을 조정하고자 할 경우에는 승강로드(321)의 나사부(322)에 나사결합된 챔버(323)를 회전시켜 충진되는 액체의 량을 조정할 수 있다.In the quantitative discharge pump 100 of the present invention, in order to adjust the discharge amount of the liquid 440 to be discharged by rotating the chamber 323 screwed to the screw portion 322 of the lifting rod 321 The amount of liquid to be filled can be adjusted.
즉 나사부(322)에 나사결합된 챔버(323)를 회전시켜 가이드(331)의 외면을 슬라이드하여 에어실린더(300)쪽으로 이동되게 하면 가이드(331)를 따라 슬라이드하는 챔버(323)의 이동거리가 그만큼 짧아지게 되고, 따라서 작동실(310)내에 끼워진 에어피스톤(320)의 이동거리 역시 짧아지면서 계량피스톤(220)에 의해 토출되는 액체(440)의 량이 적어지게 된다.That is, by rotating the chamber 323 screwed to the screw 322 to slide the outer surface of the guide 331 to move toward the air cylinder 300, the movement distance of the chamber 323 sliding along the guide 331 is As it is shortened, the movement distance of the air piston 320 inserted in the operation chamber 310 is also shortened, so that the amount of the liquid 440 discharged by the metering piston 220 is reduced.
액체(440)의 토출량을 증가시키고자 할 경우에는 챔버(323)를 위와는 반대로 조작하여 에어피스톤(320)의 이동거리를 길게할 경우에는 액체(440)의 토출량이 많아지게 된다.In order to increase the discharge amount of the liquid 440, the discharge amount of the liquid 440 increases when the moving distance of the air piston 320 is increased by operating the chamber 323 as opposed to the above.
챔버(323) 외측에 위치한 잠금너트(324)는 챔버(323)를 이용하여 액체(440)의 토출량을 조정한 다음 잠금너트(324)를 챔버(323)와 밀착되게 체결하여 작동중 챔버(323)가 이동하여 액체의 토출량이 달라지는 것을 방지한다.The lock nut 324 located outside the chamber 323 adjusts the discharge amount of the liquid 440 using the chamber 323, and then locks the lock nut 324 tightly to the chamber 323 to operate the chamber 323. ) To prevent the discharge amount of the liquid from changing.
이상 설명한 바와 같이 본 발명은 오일이나 접착제, 약품등과 같은액체를 토출함에 있어서, 피스톤에 의해 스풀이 승강되게 하므로서 액체의 유입 및 토출통로를 선택적으로 개폐되게 하고, 동시에 계량본체내에 끼워진 계량피스톤이 전후진하여 계량실내에 필요한 량의 액체를 흡입시킨다음 토출되게 하고, 또한 챔버를 이용하여 액체의 토출량을 미세조정할 수 있게 되는 등의 효과가 있는 것이다.As described above, in the present invention, when discharging a liquid such as oil, adhesive, or chemical agent, the spool is lifted by the piston to selectively open and close the inflow and discharge passage of the liquid, and at the same time the metering piston embedded in the weighing body By moving forward and backward, the required amount of liquid is sucked into the metering chamber and then discharged, and the discharge amount of the liquid can be finely adjusted using the chamber.
