1 and 2 illustrate a hose connection system for chemical supply according to an embodiment of the present invention.

1 and 2, the chemical supply hose connection system according to an embodiment of the present invention is a system for automatically or manually connecting the chemical supply hose 20 to the chemical storage facility 40 , The guide rail 100 and the transfer unit 200 may be included, and a locking unit 300 and/or a control unit (not shown) may be optionally further included according to an embodiment.

In general, two hoses 20 and 30 are used in the process of supplying chemicals to the chemical storage facility 40 from a chemical supply source (not shown) such as a tank lorry. One of the two hoses is a chemical hose 20 that supplies chemicals from the chemical supply source to the chemical storage facility 40, and the other is to fill the chemical storage tank of the chemical source with a filling gas such as nitrogen to facilitate chemical discharge. In order to do this, it is a filling gas hose 30 that supplies a filling gas from the chemical storage facility 40 to a chemical supply source.

The chemical storage facility 40 is a facility provided in a chemical use place that uses various chemicals, such as a semiconductor factory or a chemical factory, and a corresponding coupler to which couplers 22 and 42 provided at the ends of the hoses 20 and 30 are connected. (42, 44), a storage tank (not shown) for storing the chemical supplied through the counterpart coupler 42 on one side, a gas supply source (not shown) for supplying a filling gas such as nitrogen through the counterpart coupler 44 on the other side, It may include a transfer pipe (not shown) for transferring the chemical and the filling gas.

Chemicals supplied and stored in the chemical storage facility 40 include gaseous or liquid chemical substances such as hydrofluoric acid, sulfuric acid, hydrochloric acid, ammonia, hydrogen peroxide, plating solution, photoresist, or developer, or used for chemical mechanical polishing (CMP). Various chemical substances, such as paste-like chemical substances such as slurries, may be included.

On the other hand, in the drawing, on the side of the filling gas hose 30 and the corresponding coupler 44 on the other side, unlike the chemical hose 20 and the corresponding coupler 42 on the other side, the guide rail 100 and the transfer unit ( 200) is not shown, because the relatively non-dangerous filling gas hose 30 can be connected manually by the operator. However, it goes without saying that the chemical supply hose connection system described below can be applied equally to the filling gas hose 30 side. Therefore, hereinafter, a description will be given of a case in which the chemical supply hose connection system of the present embodiment is applied to the chemical hose 20 side, but the present invention is not limited thereto.

In addition, in the following description, the hose connection system for chemical supply is described as an example of supplying chemicals from a chemical supply source such as a tank lorry to the chemical storage facility 40, but on the contrary, the tank lorry or drum in the chemical storage facility 40 In the case of supplying chemicals to chemical transport equipment such as containers, the hose connection system for supplying chemicals of the present invention may be applied. In this case, the chemical storage facility 40 may be a manufacturing place of chemicals, not a use place of the chemicals.

First, with reference to FIG. 3, the configuration of the chemical supply hose 20 used in the chemical supply hose connection system of the present invention will be described.

As shown in Fig. 3, the chemical supply hose 20 has flexibility and a coupler 22 is coupled to its end. In general, the coupler 22 coupled to the end of the chemical supply hose 20 is composed of a male coupler, and the corresponding coupler 42 of the chemical storage facility 40 is connected by inserting a male coupler. It consists of a female coupler.

The distal end (22a) of the coupler (22) is formed with an outlet, and its outer circumferential surface indicates the correct connection posture of the coupler (22) and the type of chemical supplied through the hose (20) in the process of connection with the corresponding coupler (42). A key code 22b to be able to be identified may be formed. For example, the key code 22b of the coupler 22 may be composed of a plurality of grooves formed along the outer circumferential surface of the coupler 22. In this case, a corresponding key code may be formed on the inner circumferential surface of the corresponding coupler 42. That is, the corresponding key code of the corresponding coupler 42 is a plurality of protrusions that are mated with the key code 22b of the coupler 22 when the coupler 22 is inserted into the opening of the corresponding coupler 42 in a correct posture. Can be configured. It goes without saying that according to the embodiment, the key code 22b of the coupler 22 may be configured as a protrusion, and the corresponding key code of the corresponding coupler 42 may be configured as a groove.

On the other hand, the coupling of the hose 20 and the coupler 22 includes a first flange 24, which is a flange for coupling a coupler provided on the side of the hose 20, and a second flange, which is a flange for fixing a coupler, which is provided on the side of the coupler 22. It can be achieved by fixing 26 to each other with fastening members 28 such as bolts and nuts. In this case, a gasket may be interposed between the first flange 24 and the second flange 26.

It goes without saying that the technical configuration of the above-described chemical supply hose can be applied equally to the chemical hose 20 as well as the filling gas hose 30.

Referring back to FIGS. 1 and 2, the guide rail 100 is mounted with a hose 20 including flanges 24 and 26 of a chemical supply hose and a coupler 22, and the hose 20 corresponds It supports so as to be movable forward (+X direction) approaching toward the coupler 42 or rearward (-X direction) away from the corresponding coupler 42. The guide rail 100 is provided at a height at which the coupler 22 can be coupled to the corresponding coupler 42 when the hose 20 moves forward, and is fixed to a frame or structure not shown. In addition, the guide rail 100 is formed in a tunnel shape that surrounds at least a portion of the outer circumferential surfaces of the flanges 24 and 26 and has an open front end and a rear end thereof.

Specifically, the guide rail 100 supports the hose 20 and guides the main rails 110a and 110b to be movable forward and backward, and the sub rail 120a to guide the transfer unit 200 to be slidable forward and backward. 120b, 130) may be provided.

In this embodiment, the main rail (110a, 110b) is made of a pair of left and right symmetrical, the inner circumferential surfaces of the pair of main rails (110a, 110b) facing each other are flanges (24, 26) when the hose (20) is mounted. ), each has an arc shape so as to surround at least a portion of the outer circumferential surface. Here, since the outer circumferential surfaces of the flanges 24 and 26 are circular, the inner circumferential surfaces of the main rails 110a and 110b facing each other are configured in an arc shape, but when the outer circumferential surfaces of the flanges 24 and 26 are polygonal, the corresponding It goes without saying that the shape of the inner circumferential surface of the main rails 110a and 110b may be polygonal.

As such, the pair of main rails 110a and 110b wraps the outer circumferential surfaces of the flanges 24 and 26 when the hose 20 including the flanges 24 and 26 is mounted therebetween so that the hose 20 moves downward. It can be supported stably without falling out.

In addition, by configuring the main rails 110a and 110b as a pair, the guide rail 100 as a whole is opened so that the lower parts of the flanges 24 and 26 are exposed when the hose 20 is mounted. There is a structure. This is advantageous in preventing contamination or damage to the guide rail 100 or surrounding components even if the residual amount of chemicals flows out of the coupler 22 and falls to the floor of the space where the system is installed.

Further, by configuring the main rails 110a and 110b as a pair, the guide rail 100 as a whole has a structure in which the upper part is open. This means that a member for gripping the hose 20 of the transfer unit 200 to be described in detail below and moving in the front-rear direction passes in the vertical direction (Z direction), and the inner space of the guide rail 100, that is, a pair of It is intended to be able to be placed in the space between the main rails (110a, 110b).

The sub-rails 120a, 120b, and 130 are rails that guide the sliding of the transfer unit 200, which will be described in detail below, and each of the sliding blocks 220a, 220b, and 230 is mounted. Each of the sliding blocks 220a, 220b, and 230 corresponding to the sub-rails 120a, 120b, and 130 may be implemented as an LM guide.

In addition, a driving unit (not shown) for driving the corresponding sliding block 230 in the front-rear direction (X direction) is installed on the sub-rail 130 provided on the outer surface of the main rail 110a. The driving unit may be implemented as a power transmission mechanism such as a linear motor, a hydraulic or pneumatic cylinder, or a gear mechanism such as a motor and a rack and a pinion. In addition, a stopper 140 is provided at the front and rear ends of the sub rail 130 to limit the range of sliding of the corresponding sliding block 230 in the front and rear direction (X direction).

On the other hand, the sub-rails 120a, 120b, and 130, the sliding blocks 220a, 220b, and 230, respectively, and the installation position or number of the driving units are not limited to the illustrated example and can be changed as much as possible.

The transfer unit 200 is a member that is slidably coupled to the guide rail 100 to move the hose 20 mounted on the guide rail 100, and eventually the coupler 22 forward or backward.

The transfer unit 200, as shown in Figs. 2 and 4, the unit frame 210, the sliding blocks 220a, 220b, 230 fixed or mounted on the unit frame 210, the first stopper 242 ), a second stopper 244, a key code alignment jig 250, and the like.

The sliding blocks 220a, 220b, and 230 are fixed to the unit frame 210 and mounted on each of the corresponding sub-rails 120a, 120b, and 130 as described above, and are mounted on the sub-rails 130 by a driving unit provided on the sub-rail 130. When the sliding block 230 moves in the front and rear direction, the unit frame 210 and the sliding blocks 220a, 220b, 230 fixed or mounted on the unit frame 210, the first stopper 242, the second stopper 244 ), the key code alignment jig 250, and other constituent parts can move together in the front-rear direction.

The first stopper 242 is a member that restricts the front surface of the flange 26 of the hose 20 mounted on the guide rail 100 so that the hose 20 cannot move forward beyond the transfer unit 200 to be. In this embodiment, the first stopper 242 is fixed to the unit frame 210 through the flange seating ring 240.

The flange seating ring 240 has a ring shape in which the rear (-X direction) is completely open, and the front (+X direction) secures at least a space through which the coupler 22 can pass, and a part of the periphery is blocked. The inner diameter of the flange seating ring 240 is the same as or slightly larger than the outer diameters of the flanges 24 and 26, and the outer diameter of the flange seating ring 240 is of the space formed between the pair of main rails 110a and 110b. It is formed slightly smaller than or equal to the inner diameter.

The first stopper 242 is implemented as a plate-shaped member that blocks a part of the periphery of the front opening of the flange seating ring 240. The first stopper 242 may be integrally formed with the rest of the flange seating ring 240.

With such a structure of the flange seating ring 240 and the first stopper 242, the flange seating ring 240 is fixed to the unit frame 210 and the sliding blocks 220a, 220b, 230 of the transfer unit 200 When mounted on each of the corresponding sub-rails 120a, 120b, and 130, the flange seating ring 240 is disposed in an inner space formed between the pair of main rails 110a, 110b. In addition, in this state, when the hose 20 is inserted from the rear of the flange seating ring 240 into the space between the pair of main rails 110a and 110b, the flanges 24 and 26 of the hose 20 It is stably seated on the inner circumferential surface of 240 and the front side surface of the flange 26 is caught by the first stopper 242 and is not inserted any more, and the front-rear position is aligned.

In the second stopper 244, when the flanges 24 and 26 of the hose 20 are seated on the inner circumferential surface of the flange seating ring 240, the rear surface of the flange 24 is caught and the hose 20 is transferred to the transfer unit ( It is a member that restricts movement backward beyond 200). In this embodiment, the second stopper 244 is fixed to the unit frame 210 via a rotation motor 246 (see FIGS. 5 and 6 ).

The rotation motor 246 is a member that rotates the second stopper 244 between an operating position in which the second stopper 244 can function as a stopper and a retracted position that does not interfere with the movement of the hose 20. This is, unlike the above-described first stopper 242, which is always fixed in the operating position, the second stopper 244 mounts the hose 20 on the guide rail 100 or removes the hose 20 from the guide rail 100. This is because when separating, the movement of the hose 20, in particular the flanges 24 and 26, to the front or the rear must not be impeded.

Specifically, referring to FIG. 5, in order to mount the hose 20 on the guide rail 100, the flanges 24 and 26 are inserted by inserting the hose 20 into the space between the pair of main rails 110a and 110b. When seating on the flange seating ring 240, a rotation motor 246 is used so that the flanges 24 and 26 of the hose 20 inserted in the front (+X direction) do not get caught in the second stopper 244. The second stopper 244 is rotated to a retracted position higher than the uppermost portions of the flanges 24 and 26.

In addition, referring to FIG. 6, when the flanges 24 and 26 are seated on the flange seating ring 240 and the hose 20 is mounted on the guide rail 100, the rotation motor 246 is a second stopper ( Rotate 244 to an operating position in close contact with the rear surface of the flange 24.

With the structure of the first stopper 242 and the second stopper 244 as described above, when the transfer unit 200 slides forward when the second stopper 244 is in the operating position, the second stopper 244 moves together. ) Pushes the rear surface of the flange 24 so that the hose 20 can move forward (see FIGS. 6 and 7 ). On the other hand, when moving the hose 20 to the rear, it is sufficient to slide the transfer unit 200 to the rear. Then, the first stopper 242, which is always fixed in the operating position, moves backward together with the transfer unit 200 and pushes the front surface of the flange 26 so that the hose 20 moves backward.

On the other hand, in this embodiment, the second stopper 244 is configured to be located in the operating position or the retracted position by rotating on the XZ plane about a rotation axis parallel to the Y axis by the rotation motor 246, but the second stopper 244 ) May be configured to be located in the operating position or the retracted position by lifting up and down along the Z direction. In this case, instead of the rotation motor 246, an actuator such as a hydraulic or pneumatic cylinder may be used.

Further, in this embodiment, the hose 20, that is, the flanges 24 and 26 are stably mounted using the flange seating ring 240, but the flange seating ring 240 may be omitted. In this case, the hose 20, that is, the flanges 24 and 26, is directly mounted in the inner space of the guide rail 100, that is, the space between the pair of main rails 110a and 110b, and the first stopper 242 Has a structure that is directly fixed to the unit frame 210.

Meanwhile, as described above, a key code 22b may be provided on an outer circumferential surface of the coupler 22, and a corresponding key code may be provided on an inner circumferential surface of the corresponding coupler 42. At this time, the corresponding key code of the corresponding coupler 42 is provided based on a predetermined reference direction (eg, 12 o'clock), so that the coupler 22 is in an accurate posture, that is, the key code 322b of the coupler 22 is The coupler 22 and the corresponding coupler 42 are properly connected to each other when they are aligned in this reference direction and inserted into the opening of the corresponding coupler 42. Therefore, when mounting the hose 20 on the guide rail 100, it is necessary to mount the key code 322b of the coupler 22 so that it is aligned in the reference direction. To this end, in this embodiment, the key code alignment jig 250 ).

The key code alignment jig 250 has a front end surface in contact with the outer peripheral surface of the coupler 22 of the portion where the key code 22b of the hose 20 is formed, as shown in FIG. 4, and the key code of the coupler 22 When (22b) is formed as a groove (refer to FIG. 3), the protrusion 252 may have a shape and size corresponding to the groove and protrude from the front end surface in the reference direction. Of course, when the key code 22b of the coupler 22 is formed as a protrusion, the key code alignment jig 250 may have a groove having a shape and size corresponding to the protrusion. Therefore, when the hose 20 is mounted on the guide rail 100, the coupler 22 is in an accurate posture by simply aligning the key cord 22b of the coupler 22 with the protrusion 252 of the key cord alignment jig 250. Are arranged as.

Meanwhile, the protrusion 252 may be formed of a ball plunger. The ball plunger has a ball having a spherical or hemispherical shape at its tip end, and a spring that elastically supports the ball is disposed at the rear end of the ball, thereby making key cord alignment more flexible and easier.

The key code alignment jig 250 may be provided while being fixed to the unit frame 210 of the transfer unit 200 so as to be movable forward or backward together with the transfer unit 200. In addition, the key code alignment jig 250 is fixed to the unit frame 210 so as to be elevating and moving forward and backward through the jig support 260 at the front end of the transfer unit 200. Specifically, the jig support 260 has an approximately L shape when viewed from the side, and a portion parallel to the ground (XY plane) of the jig support 260 is attached to the unit frame 210 through the advance and retreat driving unit 264. It is fixed, and the jig support 260 is capable of moving forward and backward with respect to the unit frame 210 (X direction). In addition, a key code alignment jig 250 is fixed to a portion perpendicular to the ground (XY plane) of the jig support 260 through an elevating driving unit 254, and the key code alignment jig 250 is a jig support 260 It is possible to move up and down in the vertical direction (Z direction). Here, the forward and backward driving unit 264 and the lifting driving unit 254 may be implemented as actuators such as a linear motor or a hydraulic or pneumatic cylinder.

In this way, the key code alignment jig 250 is fixed to the unit frame 210 via the elevating driving unit 254, the jig support 260, and the forward and backward driving unit 264, so that the key code alignment jig 250 is a transfer unit. With 200, it is possible to move in the front-rear direction (X direction), and can move in the front-rear direction (X direction) independently of the transfer unit 200, and it is also possible to move up and down (Z direction). In this way, the key code alignment jig 250 can be moved in the X direction independently of the transfer unit 200 and can be moved up and down in the Z direction, and the hose 20 is mounted on the guide rail 100 or the guide rail 100 ) When moving along the front end surface of the key code alignment jig 250 to the key code 22b of the coupler 22 (see FIGS. 5 and 6), and the coupler 22 to the corresponding coupler 42 It is intended to be retractable to the retracted position (see FIG. 7) so as not to interfere with the movement of the coupler 22 to the front when it is finally inserted and connected.

The operation of the hose connection system for chemical supply according to the present embodiment configured as described above will be described with reference to FIGS. 5 to 7. 5 to 7 are right side views of the system according to the present embodiment, and the illustration of the right main rail 110b is omitted for convenience of understanding.

First, as shown in FIG. 5, in a state in which the transfer unit 200 is retracted to the rear (-X direction) of the guide rail 100, the jig support 260 is driven forward (+X direction), and The key code alignment jig 250 is driven downward so that the front end surface (lower end in the drawing) of the key code alignment jig 250 is located in the inner space of the guide rail 100. At this time, the second stopper 244 is in a state that has been retracted to the retracted position using the rotation motor 246.

Subsequently, the hose 20 is mounted on the guide rail 100. Specifically, the hose 20 is inserted into the space between the pair of main rails 110a and 110b so that the key code 22b of the coupler 22 is at the 12 o'clock position, and the flanges 24 and 26 are flanged. When seated on the seating ring 240, the protrusion 242 of the key code alignment jig 250 is inserted into the key code 22b so that the coupler 22 is aligned with the correct connection posture. When the alignment of the coupler 22 is completed, the rotation motor 246 is driven to position the second stopper 244 in an operating position in close contact with the rear surface of the flange 24.

Subsequently, as shown in FIG. 6, the second stopper 244 pushes the rear surface of the flange 24 by sliding the transfer unit 200 in the front (+X direction) of the guide rail 100. 20) is moved forward, and a part of the tip end of the coupler 22 is temporarily stopped while being inserted into the opening of the corresponding coupler 42.

At this time, the key code alignment jig 250 is in contact with the key code 22b of the coupler 22. Therefore, the complete connection of the coupler 22, that is, the key code 22b of the coupler 22 is completely inserted, so that the key code 22b and the corresponding key code are matched, and the coupler 22 and the corresponding coupler 42 are connected. In order to make it into a state, it is necessary to retreat the key code alignment jig 250 to the retracted position. To this end, first, by driving the lift driving unit 254, the key code alignment jig 250 is raised upward (Z direction), and then the advance and retreat driving unit 264 is driven to move the key code alignment jig 250 to the rear (-X). Direction).

Subsequently, when the transfer unit 200 is further slid further forward, the coupler 22 is completely inserted into the opening of the corresponding coupler 42 to connect the coupler 22 and the corresponding coupler 42 as shown in FIG. 7. This is done.

On the other hand, the separation of the coupler 22 and the corresponding coupler 42 may be performed in the reverse order of connection. However, since it is not necessary to check and align the key code 22b during separation, the key code alignment jig 250 remains as shown in FIG. 7 and slides the transfer unit 200 to the rear to mount the hose 20. It moves to the position, that is, the position of FIG. 5.

Subsequently, the second stopper 244 is retracted from the operating position to the retracted position using the rotation motor 246, and the hose 20 is removed from the guide rail 100 and separated.

On the other hand, the locking unit 300, which is additionally provided according to the embodiment, is in close contact with the coupler 22 connected to the corresponding coupler 42 after the connection between the coupler 22 and the corresponding coupler 42 is completed. It is configured to maintain a connection state between the corresponding couplers 42.

8 and 9 are diagrams showing the configuration and operation of the locking unit 300 of the system according to the present embodiment.

As shown in FIG. 8, the locking unit 300 may include an eccentric cam 310, a cam lever 320, a driving rod 340, and an actuator 360.

The eccentric cam 310 is rotatably installed around the rotation shaft 312 around the opening 42a of the corresponding coupler 42, and is inserted into and connected to the opening 42a of the corresponding coupler 42 according to the rotation angle. It is configured to be in close contact with the outer peripheral surface of the coupler 22 or to be spaced apart from the outer peripheral surface of the coupler 22.

The cam lever 320 extends from the eccentric cam 310 to rotate the eccentric cam 310. The cam lever 320 is connected to the driving rod 340 by a connection pin 330 at an end opposite to the eccentric cam 310. The driving rod 340 includes a pin receiving portion 350 to which a connection pin 330 is inserted and fixed at one end, and the other end is connected to the actuator 360. The actuator 360 may be implemented by a pneumatic or hydraulic cylinder, and is driven upward and downward to move the eccentric cam 310 through the driving rod 340 and the cam lever 320 in one direction or the one direction within a predetermined rotation angle range. It is configured to rotate in the reverse direction of.

That is, as shown in FIG. 9, when the coupler 22 is inserted into and connected to the opening of the corresponding coupler 42, the actuator 360 raises the driving rod 340, and the cam connected to the driving rod 340 The lever 320 and the eccentric cam 310 connected to the cam lever 320 are rotated to the locking position. As a result, the eccentric cam 310 is in close contact with the outer circumferential surface of the coupler 22 to maintain a connected state between the coupler 22 and the corresponding coupler 42.

On the other hand, when the chemical supply is complete, the actuator 360 lowers the driving rod 340 to lock the cam lever 320 connected to the driving rod 340 and the eccentric cam 310 connected to the cam lever 320 Rotate to the released position. As a result, the eccentric cam 310 is spaced apart from the outer circumferential surface of the coupler 22 so that the coupler 22 can be separated from the corresponding coupler 42.

Here, the cam lever 320 and the driving rod 340 may be configured to be mutually coupled and separated by inserting and separating the connection pin 330 into the pin receiving portion 350 by manual manipulation. When the cam lever 320 and the driving rod 340 are separated in this way, the cam lever 320 is in a state in which the cam lever 320 can be operated manually without a separate manipulation of the actuator 360. For reference, some of the cam lever 320 and the driving rod 340 in FIGS. 1, 2, and 5 to 7 are shown in a separate state, which is for better understanding. The cam lever 320 and the driving rod 340 are in a coupled state.

For example, when an emergency situation occurs, such as a failure of some components while the system is operating in the automatic mode, or the operation mode is a manual mode, the driving rod 340 of the locking unit 300 and the cam lever 320 are separated, and The cam lever 320 may be manually rotated to lock or unlock the coupler 22. Further, the transfer unit 200 may be manually operated by an operator directly pushing or holding it. In this case, the operator may manually connect or disconnect the coupler 22 and the corresponding coupler 42.

In addition, according to the embodiment, the chemical supply hose connection system is composed of a combination of computer hardware and a computer program read and executed by a computer, and a control unit that controls the operation of the transfer unit 200 and the locking unit 300 It may further include (not shown). In this case, the control unit may be configured in the form of a separate console that can be operated by an operator.

As described above, according to the present invention, system components such as guide rails are not disposed under the hose 20. Therefore, in the process of moving, connecting, or disconnecting the hose 20, the system configuration that is disposed around the guide rail 100 as well as the guide rail 100 from the remaining amount of chemicals flowing out and falling from the coupler 22 or the corresponding coupler 42 Elements can be protected from contamination or damage.

In addition, it is possible to fix (grasp) and move the hose 20 only with the first and second stoppers 242 and 244 without using a clamp, which is a heavy object conventionally used for fixing the hose. Therefore, it is possible to reduce the weight and simplify the system.

In addition, according to the embodiment, the cam lever 320 and the driving rod 340 may be coupled and separated, and further, the sliding operation of the transfer unit 200 may be manually performed. Therefore, it is possible to flexibly cope with emergency situations such as system failure.
