Description

Camlock Coupling Device and Fluid Transfer System Using the Same

The present invention relates to a technology for connecting a hose or a fluid pipe between two fluid sources and transferring a fluid, and more particularly, to a camlock coupling device and a fluid transport system for coupling two fluid sources by a camlock coupling method.

For example, a camlock coupling is widely used to connect a fire hose to a fire hydrant or a water tank of a fire engine, or to connect two hoses or a fluid pipe. The cam lock coupling is performed by inserting a cam lock adapter 20 having a concave portion 20a formed on its outer circumferential surface into the cam lock coupler 10 provided with a lever 11 as shown in FIG. 1 (see arrow a), and the lever By bending (11) toward the rear hose 15 side of the cam lock coupler 10 (see arrow b), the cam 11a formed on the fixed end (end on the rotation shaft 12 side) of the lever 11 is connected to the cam lock adapter ( 20) While being accommodated in the concave portion 20a formed on the outer circumferential surface, the cam lock adapter 20 is brought into close contact with the gasket 13 provided inside the cam lock coupler 10 to couple the cam lock coupler 10 and the cam lock adapter 20. is carried out On the other hand, the disengagement of the cam lock coupler 10 and the cam lock adapter 20 is performed in the reverse order as above.

As described above, the camlock coupling has a relatively large coupling tolerance and has a simple structure and has the advantage that high-pressure fluid connection is possible without fluid leakage. When this occurs, eccentricity or inclination occurs in the cam-lock coupler 10 and the cam-lock adapter 20, and the sealing by the gasket 13 is incomplete, so there is a risk of fluid leakage.

On the other hand, in semiconductor factories or chemical factories, if a fluid leak occurs when transporting flammable or harmful chemicals to the human body or environment, there is a risk of safety accidents such as personal injury or fire, and pollutants in the air during fluid transport. If this is mixed, it may cause a defect in the manufactured product.

Therefore, an expensive connection device called ACQC (Automatic clean quick coupler) is used to transfer fluids such as chemicals that are concerned about leakage or contamination of the fluid. In a system that automatically connects the male and female connectors due to temporary factors such as vibration of the drive device or pump, and various factors such as deformation of the frame or male and female connectors, the durability of the system may be reduced due to abrasion due to eccentricity, sealing failure, etc. There is a problem such as falling and leakage of fluid (see Patent Document 1).

The fixed bridge 315 includes two pillars 315a of a predetermined height provided at both ends, and a top plate 315b spanning the upper ends of the two pillars 315a. The fixed bridge 315 is provided with a moving stage driving unit operating as an adapter driving unit in the present embodiment.

The moving stage 320, as shown in FIGS. 5 and 8, is formed in a long plate shape in the left-right direction (X-axis direction), and is mounted on a guide rail 312 installed on the upper surface of the fixed stage 310 with an LM guide ( 321) interposed therebetween to be slidably installed in the front and rear (Y-axis direction). A plurality of through-holes 322 (refer to FIG. 7 ) intersecting with the long holes 311 of the fixed stage 310 are drilled in the moving stage 320 in the same number as the number of the long holes 311 . A connection pin 325 is passed through each through hole 322 .

The moving stage driving unit is a configuration for sliding the moving stage 320 forward and backward (Y-axis direction), and is installed on the fixed bridge 315 . In the present embodiment, the moving stage driving unit is implemented by a ball screw method, but the moving stage driving unit may be implemented by an equivalent means such as a linear motor or a rack and pinion gear.

Specifically, referring to FIG. 8 (in FIG. 8, the upper plate 315b of the fixed bridge 315 shown in FIG. 5 is omitted for convenience of understanding), the moving stage driving unit includes a ball screw 331, a ball nut ( 332 , a belt 333 and pulleys 334a and 334b and a drive motor 335 . The ball screw 331 is rotatably installed between the two pillars 315a of the fixed bridge 315 . The ball nut 332 is fixed on the moving stage 320 and the ball screw 331 is passed through the front and rear. The driving motor 335 is a component for rotating the ball screw 331 , and is fixed to the lower surface of the upper plate 315b of the fixed bridge 315 through the pulley housing 336 . In the pulley housing 336, the driving pulley 334a coupled to the rotation shaft of the driving motor 335, the driven pulley 334b coupled to the ball screw 331, and the driving pulley 334a and the driven pulley 334b for connecting the driven pulley 334b A belt 333 is installed. Accordingly, when the driving motor 335 rotates, a rotational force is transmitted through the driving pulley 334a, the belt 333 and the driven pulley 334b to rotate the ball screw 331, and accordingly the ball nut 332 and The moving stage 320 to which the ball nut 332 is fixed moves forward and backward.

On the other hand, in the present embodiment, the belt 333 and pulleys 334a and 334b are used as the power transmission mechanism of the drive motor 335 and the ball screw 331, but the power transmission mechanism is other equivalent means such as a gear mechanism. can also be implemented. In addition, in this embodiment, the drive motor 335 is fixed to the lower surface of the upper plate 315b of the fixed bridge 315 through the pulley housing 336, but the width of the upper plate 315b is widened to support the driving motor 335. It may be directly fixed to the lower surface of the upper plate 315b, or the driving motor 335 may be disposed on the upper surface of the upper plate 315b.

As shown in FIG. 7 , the adapter support 340 is a member into which the adapter 20 is inserted and fixed, and the LM guide 341 is interposed on the guide rail 313 installed on the lower surface of the fixing stage 310 . It is installed slidably in the front and rear (Y-axis direction). That is, the adapter support 340 is slidably installed while being suspended from the lower surface of the fixed stage 310 . At the upper end of the adapter support 340 , a locking groove 340a is formed in which the connecting pin 325 is inserted and caught at a position that intersects the long hole 311 of the fixing stage 310 . Therefore, when the connecting pin 325 is inserted into the locking groove 340a, the adapter support 340 is physically connected to the moving stage 320, and when the moving stage 320 moves forward and backward (Y-axis direction), the adapter support unit The adapter 20 fixed to the 340 and the adapter support 340 also moves forward and backward together. That is, the moving stage driving unit composed of the ball screw 331, the ball nut 332, the belt 333, pulleys 334a, 334b, and the driving motor 335 is an adapter driving unit that moves the adapter 20 forward and backward. function

On the other hand, the connection pin 325 may be configured to be liftable up and down. Specifically, the connecting pin 325 is fixed to the movable stage 320 so as to be liftable by a driving means such as an air cylinder 326 . In a state in which the connecting pin 325 is raised by the air cylinder 326 (see FIG. 7 ), the connecting pin 325 is not inserted into the engaging groove 340a so that the adapter support 340 is physically attached to the moving stage 320 . is not connected, and therefore, even if the moving stage 320 moves forward and backward, the adapter support 340 does not move. On the other hand, in the state in which the connection pin 325 is lowered (see FIG. 9 ), the connection pin 325 is inserted into the locking groove 340a so that the adapter support 340 is physically connected to the moving stage 320 , in this state When the moving stage 320 moves forward and backward, the adapter support 340 also moves. That is, the adapter support 340 may be selectively connected to the moving stage 320 by the connecting pin 325 .

By selectively connecting the adapter support 340 and the moving stage 320 in this way, a specific adapter support 340 among the adapter support parts 340 installed in plurality is selectively moved, or a single long hole 311 . The adapter support 340 disposed below and the cap detachable unit 350 to be described later may be selectively moved.

On the other hand, in this embodiment, as described above, the coupler 10 and the adapter 20 are used in a state in which the coupler cap 17 and the adapter cap 27 are respectively covered. Therefore, in order to couple the coupler 10 and the adapter 20, each of the caps 17 and 27 must be separated, and the transfer of the fluid is completed, so that each of the caps 17 and 27 is attached to the coupler 10 and the adapter 20. 27) must be installed. To this end, the system of this embodiment further includes a cap detachable unit 350 .

The cap detachable unit 350 is slidably installed in the front and rear (Y-axis direction) of the adapter support 340 on the lower surface of the fixed stage 310 . That is, the cap detachable unit 350 is installed to be slidably suspended from the lower surface of the fixed stage 310 like the adapter support 340 . Specifically, referring to FIG. 7 , the cap detaching unit 350 includes a base plate 351 , a support frame 353 , and a cap gripping unit 354 .

The base plate 351 is slidably installed in the front and rear (Y-axis direction) through the LM guide 352 on the guide rail 314 installed on the lower surface of the fixed stage 310 .

The support frame 353 is slidably installed in the left-right direction (X-axis direction) on the guide rail 356 installed on the lower surface of the base plate 351 . This is to allow the cap detachment unit 350 to deviate from the travel path of the adapter 20 when the adapter 20 advances toward the coupler 10 after the cap detachment unit 350 separates the coupler cap 17 . it is for To this end, the cap detachment unit 350 may further include a driving means such as an air cylinder 355 for moving the support frame 353 in the left and right direction. In addition, at the upper end of the support frame 353 , a locking groove 350a is formed in which the connecting pin 325 is inserted and caught at a position that intersects the long hole 311 of the fixed stage 310 . Therefore, when the connecting pin 325 is inserted into the engaging groove 350a, the cap detaching unit 350 is physically connected to the moving stage 320, and when the moving stage 320 moves in the front and rear (Y-axis direction), the cap The detachable unit 350 also moves forward and backward together. That is, the above-described moving stage driving unit also functions as a driving unit for moving the cap detachment unit 350 forward and backward.

The cap gripping part 354 is provided with a pair of gripping arms 354a and 354b that can be vertically spread or retracted to be inserted into the coupler 10 in the coupler cap 17 (see FIG. 5) at the opposite end of the side. The formed concave portion 17b can be gripped.

Meanwhile, the adapter cap 27 may be fixed to the support frame 353 . That is, the adapter cap 27 is aligned and fixed at a position where the tip of the adapter 20 can be inserted at the rear of the cap gripping portion 354 that grips the coupler cap 17 . Accordingly, the cap detachment unit 350 may perform both detachment of the coupler cap 17 and detachment of the adapter cap 27 .

Next, the operation of the fluid transport system of the present embodiment configured as described above will be described with reference to FIGS. 5, 9 and 10 . Meanwhile, in FIG. 9 , the coupler 10 is mounted on the cam lock coupling device 100 on the far left, and in FIG. 10 it is illustrated as being coupled to the adapter 20 on the far right, but this is for convenience of illustration. It is a process of combining a coupler and an adapter in the same position as that.

First, the operator opens the door 220 of the housing (front housing 210b) (see FIG. 4 ), and inserts the coupler 10 of the hose 15 to perform fluid transfer in front of the corresponding adapter 20. It is mounted on the coupler mount 130 of the arranged cam lock coupling device 100 . At this time, as described above, the coupler cap 17 is mounted on the front end of the coupler 10 in a camlock coupling method. Therefore, the lever 11 of the coupler 10 is tilted to the engaging position (the position shown in FIGS. 2 and 3 (b)), and the rotating arm 150 of the camlock coupling device 100, the lever mounting The lever rotating unit including the block 160 and the driving rod 170 is also positioned at a position corresponding thereto (refer to the coupler mounted on the leftmost camlock coupling device 100 of FIG. 5 ).

Then, when the operator closes the door 220 and presses the operation switch of the operation panel, the clamp 140 operates to clamp the upper portion of the coupler 10 mounted on the coupler mount 130 .

Next, the moving stage driving unit drives the moving stage 320 so that the connecting pin 325 is positioned above the engaging groove 350a (refer to FIG. 7 ) of the cap detaching unit 350 . Next, the air cylinder 326 lowers the connecting pin 325 and inserts it into the locking groove 350a, the cap detachment unit 350 sets the cap gripping unit 354 apart, and the moving stage driving unit moves the moving stage. Move 320 further forward. Then, as the cap detachable unit 350 moves forward, the adapter cap 27 fixed to the cap detachable unit 350 is separated from the adapter 20 . When the cap gripping portion 354 in the open state reaches the concave portion 17b (refer to FIG. 5 ) of the coupler cap 17 , the coupler cap 17 is gripped by closing the cap gripping portion 354 .

Next, the lever rotation unit of the cam lock coupling device 100 rotates the lever 11 of the cam lock coupling device 100 to the release position (the position shown in FIGS. 2 and 3 (a)) to rotate the coupler 10 ) and the coupler cap 17 are released. Then, when the moving stage driving unit moves the moving stage 320 to the rear to withdraw the uncoupled coupler cap 17 from the coupler 10 , the state is as shown in FIG. 9 .

Subsequently, when the support frame 353 is moved to the right by driving the air cylinder 355 of the cap detachment unit 350 , the cap detachment unit 350 is physically disconnected from the moving stage 320 , and the cap gripping unit With the coupler cap 17 gripped at 354 and the adapter cap 27 fixed to the support frame 353 , it deviates from the travel path of the adapter 20 (see FIG. 10 ).

Subsequently, the moving stage driving unit further moves the moving stage 320 to the rear, and inserting the connecting pin 325 into the engaging groove 340a of the adapter support 340 , and then the moving stage driving unit moves the moving stage 320 again. move forward. Then, as the adapter support 240 moves forward, the adapter 20 and the fluid pipe 25 move forward so that the adapter 20 is inserted into the coupler 10, and the state as shown in FIG. (In FIG. 10 , the coupler 10 and the cam-lock coupling device 100 are omitted, but the adapter 20 is inserted into the coupler 10).

Then, the lever rotating unit of the cam lock coupling device 100 rotates the lever 11 to the engaging position (the position shown in FIGS. 2 and 3 (b)), thereby turning the adapter 20 into the coupler 10 ) to the cam lock coupling method. Then, it becomes like the coupler and adapter pair shown on the far right of FIG. 5 .

This establishes a connection between the first and second fluid sources, and the system opens a valve (not shown) installed at the rear of the fluid conduit 25 and operates a pump (not shown) from the second fluid source to the fluid conduit 25 , the adapter 20 , the coupler 10 , and the hose 15 to transfer the fluid to the first fluid source.

When the fluid transfer is completed, the coupler 10 and the adapter 20 are disconnected in the reverse order to the previous operation, the caps 17 and 27 are mounted on each, and then the coupler 10 by the clamp 140 is Release clamping. Then, the operator opens the door 220 and removes the coupler 10 and the hose 15 from the coupler mount 130 .

Meanwhile, immediately after the fluid transfer is completed, the fluid may remain in the fluid pipe 25 , the adapter 20 , the coupler 10 , and the hose 15 . In this state, if the adapter 20 and the coupler 10 are separated, the residual fluid may leak. Therefore, after the fluid transfer is completed and before separation of the adapter 20 and the coupler 10, an inert gas such as air or nitrogen is blown at a high pressure through the fluid pipe 25 to the fluid pipe 25, the adapter 20, and the coupler. (10), the residual fluid inside the hose 15 can be completely transferred to the tank of the first fluid source.

As such, according to the system of the present invention, all operations of fluid transfer including the camlock coupling except for the mounting and dismounting of the coupler 10 may be automatically performed. In addition, since a camlock coupling method that allows high-pressure fluid connection without fluid leakage while having a relatively large coupling tolerance is used, there is less concern about coupling failure, and durability and safety are high.

On the other hand, in the present embodiment, a case has been described in which the cam lock coupling device 100, the adapter 20, and the fluid pipe 25 are provided 5 each, and the 5 adapters 20 are selectively coupled with the coupler 10. , the present invention is not limited to the above configuration.

That is, the number of the camlock coupling device 100 , the adapter 20 , and the fluid pipe 25 may be plural other than five, and only one may be provided respectively. Furthermore, the number of the cam lock coupling device 100 , the adapter 20 , and the fluid pipe 25 may be different from each other. In addition, the same plurality of couplers 10 and the adapter 20 may be coupled at the same time.

In addition, the size or standard of the plurality of couplers 10 or adapter 20 may be different. For example, in the method of supplying compressed nitrogen in the opposite direction to the transport direction of the chemical without using a pump when transporting the chemical between the tank lorry and the storage tank as in Patent Document 1 described above, and pressurizing the chemical with the pressure, Chemical hoses and connectors of different sizes and specifications and nitrogen hoses and connectors can be used.

In addition, although the above-described embodiment describes a case in which the caps 17 and 27 are mounted on the coupler 10 and the adapter 20, respectively, these caps may not be used in some cases.

Modifications of the present invention according to these cases will be briefly described.

First, when the coupler 10 and the adapter 20 and only one of the cam lock coupling device 100 and the adapter support 340 are provided, the above-described moving stage 320 and the connecting pin 325 may be omitted. can In this case, the adapter support 340 may be directly moved forward and backward (in the Y-axis direction) on the lower surface of the fixed stage 310 by using the above-described ball screw method, or by using an air cylinder or a linear motor.

In addition, even if the plurality of adapter support parts 340 are always moved at the same time, the coupler 10 and the adapter 20 do not mount the caps 17 and 27, so there is no cap detachment unit 350 or the cap detachment unit ( Even if there is 350), if it is driven by a separate driving means instead of the common connection pin 325, the connection pin 325 is omitted and the plurality of adapter support parts 340 are passed through the long hole 311 of the fixing stage 310. It may be directly fixed to the moving stage 320 . Furthermore, in this case, the moving stage 320 and the moving stage driving unit may be installed on the lower surface of the fixed stage 310 .

In addition, when the number of the cam lock coupling device 100 and the adapter support part 340 is different from each other, for example, a plurality of the adapter 20 and the adapter support part 340 are provided, and the cam lock coupling device 100 is provided with one. In this case, the cam lock coupling device 100 may be configured to be horizontally movable in the left-right direction (X-axis direction). By doing this, the camlock coupling device 100 is moved left and right to a position corresponding to the adapter 20 to be coupled among the plurality of adapter support parts 340 , and then the adapter support part 340 is moved forward and backward (Y-axis direction). to couple the coupler 10 and the adapter 20 .

On the other hand, in the above-described embodiment, the coupler 10 and the cam lock coupling device 100 are fixed, and the adapter 20 is moved forward and backward to be coupled to the coupler 10. However, the adapter 20 and the fluid The tube 25 is fixed and the camlock coupling device 100 can move forward and backward to engage the adapter 20 .

Furthermore, in the above embodiment, it has been described that the moving unit is disposed above the coupler 10 and the adapter 20, but the above-described fixed stage 310, the moving stage 320, and the moving unit including the moving stage driving unit are It may be disposed under the coupler 10 and the adapter 20 .

A preferred embodiment of the present invention has been described above with reference to the accompanying drawings. However, since the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, various It should be understood that there may be equivalents and variations.
