Abstract
Description
Technical Field
[0001] Embodiments relate to chemical sampling devices. Background Art
[0002] Companies that handle chemicals that are harmful to the human body, for example, companies that manufacture chemicals, such as companies that manufacture semiconductors, LCDs, OLEDs, pharmaceuticals, paints, etc., use various types of chemicals in a single process or in multiple unit processes.
[0003] Generally, chemicals are supplied to a main storage tank by means of a tank truck or the like, and some chemicals stored in the main storage tank are divided and stored in a plurality of sub-storage tanks so that the chemicals can be sequentially supplied to a single unit process or individually supplied to a plurality of unit processes.
[0004] As another example, when the amount of the chemical is small or when a tanker truck cannot be used due to the nature of the chemical, the chemical may be directly supplied to the sub-storage tank by means of a drum, a bottle, or the like.
[0005] If chemicals become contaminated in tank trucks, drums, bottles, storage tanks, pipelines, etc., defects may occur in the unit process to which the chemicals are supplied.
[0006] Therefore, it is necessary to control the contamination level of chemicals to an appropriate level at key locations in various tankers, drums, bottles, storage tanks, pipelines, etc. Therefore, a sampling device has been developed that is capable of sampling chemicals at key locations.
[0007] The sampling apparatus in the related art includes a sampling chamber, a plurality of sampling lines respectively connected to a plurality of main locations and configured to supply chemicals to sampling bottles accommodated in the sampling chamber, and valves respectively installed in the plurality of sampling lines.
[0008] The operator can use the sampling device in the related art to perform the following sampling operations.
[0009] For example, the operator directly opens the cap of the sampling bottle, loads the sampling bottle into the sampling chamber, and fills the sampling bottle with the chemical by operating the valve in the sampling line (which is connected to the main location for sampling the chemical.) In addition, the operator unloads the sampling bottle filled with the chemical from the sampling chamber, directly closes the cap of the sampling bottle, and transports the sampling bottle to a location for analyzing the contamination degree of the chemical.
[0010] Generally speaking, as mentioned above, the sampling operation is mostly performed manually by an operator.
[0011] Therefore, there is a problem that there is a high possibility that the chemical is contaminated during the sampling operation due to the operator's negligence, etc. In addition, there is also a problem that there is a high possibility that the operator is exposed to the chemical.
[0012] These problems are likely to occur during the process where the operator directly opens or closes the cap of the sampling bottle.
[0013] Meanwhile, if the chemical is contaminated during the sampling operation, the reliability of the analysis result of the chemical contamination degree may be reduced. In addition, it may be inconvenient for the operator to prepare the highest level of safety equipment and wear or take off the safety equipment to protect the operator. Summary of the invention

[0120] The sampling bottle B may be loaded into the inner space of the housing 100 in a state where the cap C is coupled to the sampling bottle B. As shown in FIG.
[0121] The inner space of the housing 100 may be partitioned into a first-first inner space A1 - 1 , a first-second inner space A1 - 2 , a second inner space A2 , and a third inner space A3 by a plurality of partition walls 110 , 120 , and 130 .

[0139] The sampling bottle B held by the first bottle holding part 210 in the first-first internal space A1 - 1 may pass through the second inlet 121 and be transported to the cap separation / coupling module 300 in the first-second internal space A1 - 2 by the first bottle transporting part 251 .
[0140] The second bottle holding part 220 may hold the sampling bottle B that is transported to a position below the cap detaching / coupling module 300 in a state where the sampling bottle B is held by the first bottle holding part 210 .
[0141] The second bottle conveying member 252 can convey the second bottle holding member 220 in the Y direction. The Y direction (second direction) can be a horizontal direction parallel to or intersecting the X direction. For example, the X direction and the Y direction can intersect each other perpendicularly. Therefore, the maximum width of the housing 100 can be minimized.
[0142] The sampling bottle B held by the second bottle holding part 220 may be transported by the second bottle transport part 252 and arranged below the discharge ports of the plurality of sampling lines L1 , L2 , and L3 .
[0143] The first bottle holding part 210 may be separated from the sampling bottle B before the sampling bottle B is transported by the second bottle transporting part 252 . The second bottle holding part 220 may be separated from the sampling bottle B before the sampling bottle B is transported by the first bottle transporting part 251 .
[0144] Therefore, it is possible to prevent the operator's body from coming into contact with the second bottle holding part 220 , which may be contaminated by the scattered or overflowed chemicals during the process of filling the sampling bottle B with the chemicals discharged from the sampling lines L1 , L2 , and L3 .
[0145] The cover separation / coupling module 300 is coupled to the upper surface of the housing 100. The cover separation / coupling module 300 may extend to the inner space of the housing 100, specifically, to the first-second inner spaces A1-2, through a through hole formed in the upper surface of the housing 100.
[0146] The cap detaching / coupling module 300 may detach the cap C from the sampling bottle B and couple the cap C to the sampling bottle B. In this case, the sampling bottle B may be held by the first bottle holding part 210 and / or the second bottle holding part 220 .
[0147] The discharge module 500 may have an inlet port to introduce chemicals into the inner space of the discharge module 500 .
[0148] The inlet ports of the discharge module 500 may correspond in number and arrangement to the discharge ports of the plurality of sampling lines L1, L2, and L3. That is, the number of inlet ports formed in the discharge module 500 may be equal to the number of discharge ports of the plurality of sampling lines L1, L2, and L3. The plurality of inlet ports formed in the discharge module 500 may be arranged at the same intervals as the discharge ports of the plurality of sampling lines L1, L2, and L3.
[0149] For example, when the sampling lines L1, L2, and L3 each have an exhaust port and thus the number of exhaust ports is equal to the number of sampling lines L1, L2, and L3, the inlet ports of the discharge module 500 may be equal in number to the sampling lines L1, L2, and L3.
[0150] As another example, when a plurality of sampling lines L1, L2, and L3 are connected as one line and thus only a single discharge port is arranged in the housing 100, the number of inlet ports of the discharge module 500 may be less than the number of the sampling lines L1, L2, and L3. In this case, the number of sampling positions of the sampling bottle B can be reduced to one. Therefore, the size of the housing 100 can be reduced, and by miniaturizing the discharge module 500 and simplifying the process of conveying the sampling bottle B, the effect of reducing manufacturing and management costs can be expected.
[0151] The discharge module transport unit 600 may transport the discharge module 500 such that the plurality of inlet ports of the discharge module 500 are arranged directly below the discharge ports of the plurality of sampling lines L1 , L2 , and L3 .
[0152] For example, the discharge module conveying unit 600 can convey the discharge module 500 in the X direction, but the present disclosure is not necessarily limited thereto. The discharge module conveying unit 600 can convey the discharge module 500 in the Z direction. The Z direction (third direction) can be a vertical direction perpendicularly intersecting the X direction and the Y direction. In the latter case, the lowest position of the discharge module 500 can be arranged to be lower than the second bottle holding component 220.
[0153] Figure 5 is a block diagram of the control unit, and Figures 6 to 10 is a view showing a sampling process performed by the chemical sampling apparatus according to an embodiment of the present disclosure.
[0154] refer to Figure 5 , the chemical sampling device 10 may include an input unit 700 and a control unit 710 .
[0155] The input unit 700 may receive information on a chemical storage tank for collecting chemicals from an operator or the like.
[0156] The operator may use the input unit 700 and select one (eg, the first chemical storage tank 3 ) of the plurality of chemical storage tanks 3 , 5 , and 6 as a sampling target.
[0157] The input unit 700 may include a touch screen, but the present disclosure is not necessarily limited thereto.
[0158] The control unit 710 may control the bottle holding unit 200, the cap separation / coupling module 300, the bottle conveying unit 251, the second door 123, and the switch valves V installed in the sampling lines L1, L2, and L3 so that the sampling bottle is filled with chemicals stored in the chemical storage tanks 3, 5, and 6 (e.g., the first chemical storage tank 3 designated by the input unit 700). In addition, the control unit 710 may control the discharge module conveying unit 600 and the switch valve V so that the chemicals contained in the sampling lines L1, L2, and L3 (e.g., the sampling line L1 connected to the first chemical storage tank 3 designated by the input unit 700) connected to the chemical storage tanks 3, 5, and 6 designated by the input unit 700 are discharged to the discharge module 500 before the sampling bottle B is filled with the chemicals.
[0159] The sampling process and control logic of the control unit 710 will be described in detail below with reference to the accompanying drawings.
[0160] refer to Figures 6 to 10 , the operator may input a command for unlocking the first door 103 through the input unit 700. When the command for unlocking the first door 103 is input, the control unit 710 may control the door locking device 720 to unlock the first door 103.
[0161] When the first door 103 is unlocked, the operator may open the first door 103 , place the sampling bottle B on the first bottle holding part 210 disposed in the first-first internal space A1 - 1 , and then close the first door 103 .
[0162] The sampling bottle B can be loaded and unloaded in a state where the cap C is coupled to the sampling bottle B. Therefore, it is sufficient for the operator to wear only safety equipment with a general protection level instead of safety equipment with the highest protection level.
[0163] When a command for locking the first door 103 is input through the input unit 700 , the control unit 710 may control the door locking device 720 to lock the first door 103 .
[0164] However, the present disclosure is not necessarily limited thereto. The control unit 710 may lock the first door 103 according to a sensing value of a door sensor (not shown) that detects whether the first door 103 is closed.
[0165] The control unit 710 may maintain the locked state of the first door 103 until the operator unloads the sampling bottle B after the sampling operation is finished and the cap C is coupled to the sampling bottle B.
[0166] like Figure 6 As shown, the control unit 710 can control the first bottle holding component 210 to hold the sampling bottle B, and at the same time change the state of the first door 103 to a locked state.
[0167] Next, the operator may use the input unit 700 and select a chemical storage tank to collect chemicals. The control unit 710 may open the switch valve V installed in the sampling line L1 connected to the chemical storage tank (e.g., the first chemical storage tank 3) for collecting chemicals within a predetermined time, and may operate the pump P to discharge the chemicals contained in the corresponding sampling line L1 to the discharge module 500.
[0168] In this case, the control unit 710 may control the switch valve installed in the supply pipe as described above so that the switch valve installed in the supply pipe operates together with the switch valve V installed in the sampling line L1.
[0169] The chemicals contained in the sampling line L1 need to be discharged to the discharge module 500 because the chemicals contained in the sampling line L1 stagnate and form sediment when a predetermined time elapses and the chemicals are highly likely to be contaminated through the opened discharge port. The discharge operation can improve the reliability of analyzing the contamination degree of the chemicals.
[0170] Next, if Figure 7 As shown, the control unit 710 can control the discharge module conveying unit 600 to convey the discharge module 500 in the X direction. The control unit 710 can open the second door 123, and then control the first bottle conveying component 251 to convey the sampling bottle B to a position below the first-second internal space A1-2, specifically, a position below the cap separation / coupling module 300. The control unit 710 can close the second door 123 and control the second bottle holding component 220 to hold the sampling bottle B. The control unit 710 can control the cap separation / coupling module 300 to separate the cap C from the sampling bottle B.
[0171] However, the present disclosure is not necessarily limited thereto. The control unit 710 may perform an operation of discharging chemicals using the discharge module 500 simultaneously with or after the operation of separating the cap C. Alternatively, the cap C may be separated when the second bottle holding member 220 rotates in a state where the cap separation / coupling module 300 holds the cap C.
[0172] Next, if Figure 8As shown, the control unit 710 can separate the first bottle holding part 210 from the sampling bottle B, and then control the second bottle conveying part 252 to convey the sampling bottle B to a position below the discharge port of the sampling line L1. The control unit 710 can fill the sampling bottle B with chemicals stored in the first chemical storage tank 3 by opening the switch valve V installed in the sampling line L1 and operating the pump P for a predetermined time. However, the present disclosure is not necessarily limited to this. In a state where the second bottle holding part 220 is fixed, the control unit 710 can fill the sampling bottle B with chemicals by moving the sampling line L1 to a position above the sampling bottle B.
[0173] When some chemicals overflow during the operation of filling chemicals into the sampling bottle B, a chemical detection sensor (not shown) installed on the first partition wall 110 or the second bottle holding part 220 can detect the overflow, and the control unit 710 can stop the sampling process and issue an alarm according to the sensing value of the chemical detection sensor.
[0174] Next, if Fig. 9 As shown, the control unit 710 can control the second bottle conveying component 252 to convey the sampling bottle B to a position below the cap separation / coupling module 300. The control unit 710 can control the first bottle holding component 210 to hold the sampling bottle B. The control unit 710 can control the cap separation / coupling module 300 to connect the cap C to the sampling bottle B. The control unit 710 can separate the cap holding unit 310 from the cap C and move the cap holding unit 310 upward to return the cap holding unit 310 to the original position. In this case, the control unit 710 can control the discharge module conveying unit 600 to return the discharge module 500 to the original position. Alternatively, when the second bottle holding component 220 rotates in a state where the cap separation / coupling module 300 holds the cap C, the cap C can be connected.
[0175] Next, if Fig.10 As shown, the control unit 710 can separate the second bottle holding component 220 from the sampling bottle B, open the second door 123, and control the first bottle conveying component 251 to convey the sampling bottle B to the first-first internal space A1-1. In addition, the control unit 710 can close the second door 123, separate the first bottle holding component 210 from the sampling bottle B, and control the door locking device 720 to unlock the first door 103.
[0176] Meanwhile, a chemical sensor (not shown) for measuring the concentration of chemical smoke may be disposed in the first-first inner space A1 - 1 .
[0177] When the concentration of the chemical smoke detected by the chemical sensor is equal to or greater than a predetermined value, the control unit 710 may maintain the locked state of the first door 103 and operate the exhaust module 107 until the concentration of the chemical smoke becomes less than the predetermined value.
[0178] When the first door 103 is unlocked, the operator may open the first door 103 and then unload the sampling bottle B. The operator may put the sampling bottle B into a storage container (such as a vinyl bag) and transport the sampling bottle B to a location for analyzing the contamination degree of the chemical.
[0179] When the first door 103 is closed, the control unit 710 may change the state of the first door 103 to a locked state.
[0180] Fig.11 is a perspective view of a conveying device including a first bottle holding component according to an embodiment of the present disclosure, and Fig.12 yes Fig.11 A perspective view of the retaining component is shown.
[0181] refer to Fig.11 and Fig.12 The conveying device according to an embodiment of the present disclosure may include a first partition wall 110 , a first bottle holding member 210 , a conveying member 251 , and a sealing unit 400 .
[0182] The first partition wall 110 may partition a first space above the first partition wall 110 and a second space below the first partition wall 110. For example, the first partition wall 110 may be coupled to a housing (not shown) and divide an inner space of the housing into a first space and a second space.
[0183] The first partition wall 110 may be provided in the form of a plate extending in the X direction and the Y direction, but the present disclosure is not necessarily limited thereto. The Y direction (second direction) may be a direction perpendicular to the X direction (first direction). The Y direction may be a horizontal direction or a vertical direction.
[0184] A guide slit 111 may be formed in the first partition wall 110 .
[0185] The guide slit 111 may penetrate the first partition wall 110 in the Z direction and extend in the X direction. The Z direction (third direction) may be a direction perpendicular to the X direction and the Y direction.
[0186] The first bottle holding part 210 may hold a delivery target, for example, a sampling bottle B containing chemicals.
[0187] However, the present disclosure is not necessarily limited thereto. The sampling bottle B may be simply placed or fixed to the first bottle holding part 210 .
[0188] The first bottle holding member 210 may include a pair of clampers 210 a and a spacing adjusting member 223 .
[0189] The pair of clampers 210 a may be arranged to be spaced apart from each other in the X direction. The interval between the pair of clampers 210 a in the X direction may be adjusted by the interval adjustment member 223 .
[0190] The holder 210 a may include a seating portion 211 on which the sampling bottle B is seated, a side support portion 213 configured to support a side surface of the sampling bottle B, and an arm 215 extending from the seating portion 211 or the side support portion 213 to the interval adjusting member 223 .
[0191] The placement portion 211 and the side support portion 213 can be arranged in the first space, and the arm 215 can extend from the first space to the second space through the guide slit 111. Therefore, the sampling bottle B held by the placement portion 211 and the side support portion 213 can be arranged in the first space. However, the interval adjustment component 223 and the driving device (such as the conveying component 251 to be described below) can be arranged in the second space and are protected from exposure to chemicals or smoke.
[0192] The conveying member 251 can convey the first bottle holding member 210 in the X direction.
[0193] The conveying member 251 and / or the interval adjusting member 223 may include a pneumatic cylinder or a hydraulic cylinder, but the present disclosure is not necessarily limited thereto. The conveying member 251 and / or the interval adjusting member 223 may include various driving devices, such as a motor.
[0194] The conveying member 251 may be coupled to the first bottle holding member 210 through the bottle lifting member 253 .
[0195] The conveying member 251 may convey the bottle lifting member 253 in the X direction, and the bottle lifting member 253 may convey the first bottle holding member 210 in the Z direction.
[0196] After the first bottle holding member 210 is separated from the sampling bottle B, before the second bottle conveying member 252 conveys the sampling bottle B, the first bottle holding member 210 may be moved downward by the bottle lifting member 253 .
[0197] The conveying member 251 and the bottle lifting member 253 may each include a hydraulic cylinder or a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.
[0198] The conveying member 251 and the bottle lifting member 253 may be disposed in the second inner space A2. Therefore, it is possible to prevent the driving device (such as the conveying member 251 and the bottle lifting member 253) from being exposed to chemicals, and minimize corrosion caused by exposure to chemicals.
[0199] The sealing unit 400 may close a region of the guide slit 111 through which the first bottle holding member 210 passes.
[0200] Therefore, except for the region of the guide slit 111 in which the first bottle holding member 210 is disposed, the remaining region of the guide slit 111 may be closed by the sealing unit 400 , so that movement of chemicals or smoke through the guide slit 111 may be maximally suppressed.
[0201] The sealing unit 400 may include a pair of first shielding members 410 .
[0202] The pair of first shields 410 may be disposed at positions spaced apart from each other in the Y direction and coupled to the first partition wall 110. A guide slit 111 may be disposed between the pair of first shields 410.
[0203] Therefore, the arm 215 of the first bottle holding member 210 can move between the pair of first shielding members 410 .
[0204] The pair of first shields 410 may be detachably coupled to each other.
[0205] To this end, the pair of first shielding members 410 may have different magnetic properties.
[0206] For example, one of the pair of first shields 410 may include an N-pole permanent magnet, and the other of the pair of first shields 410 may include an S-pole permanent magnet.
[0207] Therefore, the pair of first shielding members 410 may be coupled to each other by magnetic force to close the guide slit 111. The arm 215 of the first bottle holding member 210 may move along the guide slit 111 while separating the pair of first shielding members 410. After the arm 215 passes through a portion between the pair of first shielding members 410, the pair of first shielding members 410 separated from each other by the arm 215 may be coupled to each other again by magnetic force.
[0208] The pair of first shielding members 410 may be made of a flexible material, but the present disclosure is not necessarily limited thereto.
[0209] Fig.13 yes Fig.12 Cross-sectional view of the tapered region shown.
[0210] refer to Fig.12 and Fig.13 , the arm 215 may include a tapered region 215 a that contacts the pair of first shields 410 .
[0211] The tapered region 215 a may have a cross-sectional shape whose width in the Y direction decreases toward opposite ends of the first bottle holding member 210 in the X direction.
[0212] Therefore, when the arm 215 moves, the pair of first shields 410 may be easily separated from each other, and the pair of first shields 410 may be in close contact with the arm 215 to the greatest extent.
[0213] The clamper 210 a may include a pair of rollers 217 coupled to the arm 215 so as to be rotatable about a rotation axis formed in the Z direction.
[0214] For example, the bracket 217a may be coupled to the arm 215, and the pair of rollers 217 may be rotatably coupled to the bracket 217a.
[0215] The pair of rollers 217 may be disposed at each of two opposite end portions of the first bottle holding member 210 in the X direction.
[0216] The pair of rollers 217 may be arranged to be spaced apart from each other in the Y direction. When the pair of first shielding members 410 pass between the pair of rollers 217, the interval between the pair of first shielding members 410 may be reduced. Therefore, the pair of first shielding members 410 may be in close contact with the arm 215 to the greatest extent, and the pair of rollers 217 may assist the reconnection operation of the pair of first shielding members 410.
[0217] Fig.14 is a view showing a modified example of the sealing unit.
[0218] refer to Fig.12 and Fig.14 , the sealing unit 400 may include a pair of second shielding members 420 .
[0219] Similar to the pair of first shields 410 , the pair of second shields 420 may be arranged at positions spaced apart from each other in the Y direction and coupled to the first partition wall 110 . A guide slit 111 may be arranged between the pair of second shields 420 .
[0220] Therefore, the arm 215 of the first bottle holding member 210 can move between the pair of second shielding members 420 .
[0221] The pair of second shields 420 may be detachably coupled to each other.
[0222] To this end, a protrusion 421 extending in the X direction may be formed on one of the pair of second shields 420 , and a groove 423 coupled with the protrusion 421 may be formed on the other of the pair of second shields 420 .
[0223] Therefore, when the protrusion 421 is inserted into the groove 423, the pair of second shielding members 420 may close the guide slit 111. The arm 215 of the first bottle holding member 210 may move along the guide slit 111 while separating the pair of second shielding members 420. After the arm 215 passes through a portion between the pair of second shielding members 420, when the protrusion 421 is inserted into the groove 423, the pair of second shielding members 420 separated from each other by the arm 215 may be coupled to each other again.
[0224] However, the present disclosure is not necessarily limited thereto. The plurality of protrusions 421 may be arranged along the X direction.
[0225] The pair of second shielding members 420 may be made of a flexible material, but the present disclosure is not necessarily limited thereto.
[0226] When the pair of second shields 420 pass between the pair of rollers 217 rotatably coupled to the arm 215 , the interval between the pair of second shields 420 may be reduced. Therefore, the pair of rollers 217 may press the pair of second shields 420 and assist the protrusions 421 to be inserted into the grooves 423 .
[0227] Fig.15 is a view showing another modified example of the sealing unit.
[0228] refer to Fig.15 , the sealing unit 400 may include a pair of rollers 430 , a pair of films 440 , and a rotation force supplying member 450 .
[0229] The pair of rollers 430 may be disposed at positions spaced apart from each other in the X direction and rotatably coupled to the first partition wall 110. A guide slit 111 may be disposed between the pair of rollers 430.
[0230] For example, the pair of rollers 430 may be arranged at both opposite ends of the guide slit 111 in the X direction.
[0231] The film 440 may be wound around the roller 430 and coupled to the arm 215 of the first bottle holding part 210 by a fastening member such as a bolt, an adhesive, etc.
[0232] The film 440 may be disposed on the guide slit 111 and arranged parallel to the first partition wall 110 .
[0233] The rotational force supplying member 450 may provide a rotational force to the drum 430 so that the drum 430 rotates in a direction in which the film 440 is wound.
[0234] Therefore, when the first bottle holding member 210 is conveyed by the conveying member 251, the film 440 arranged rearward from the first bottle holding member 210 is unrolled from the roller 430, but the film 440 arranged forward from the first bottle holding member 210 is wound around the roller 430 by the rotation force supplying member 450. Therefore, except for the area of the guide slit 111 in which the first bottle holding member 210 is arranged, the remaining area of the guide slit 111 can be kept closed by the pair of films 440.
[0235] The rotation force supplying member 450 may include an elastic member such as a spring coupled to the first partition wall 110 and the rotation shaft of the drum 430 .
[0236] However, the present disclosure is not necessarily limited thereto. The rotation force supply member 450 may include a control motor, etc., for providing a rotation force to the drum 430 to provide a predetermined tension to the film 440 .
[0237] Fig.16 is a perspective view of a second bottle holding member, and Fig.17 is a vertical cross-sectional view of the second tapered region.
[0238] refer to Figure 4 , Fig.16 and Fig.17 The second bottle holding member 220 may include a pair of second clampers 221 and a second interval adjusting member 223 .
[0239] The pair of second grippers 221 may be arranged to be spaced apart from each other in the Y direction. The second interval adjustment member 223 adjusts the interval between the pair of second grippers 221 in the Y direction so that the pair of second grippers 221 hold the sampling bottle B or separate the sampling bottle B.
[0240] The second interval adjusting member 223 may include a hydraulic cylinder or a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.
[0241] The second holder 221 may include a second seating portion 221 a on which the sampling bottle B is seated, a second side support portion 221 b configured to support a side surface of the sampling bottle B, and a second arm 221 c extending from the second interval adjusting member 223 to the second side support portion 221 b in the X direction.
[0242] The second arm 221 c may be disposed to pass through a second guide slit 131 formed in the third partition wall 130 .
[0243] The second guide slit 131 may penetrate the third partition wall 130 in the X direction and extend in the Y direction to guide movement of the second bottle holding member 220 in the Y direction.
[0244] The second placement portion 221a and the second side support portion 221b of the second bottle holding member 220 may be arranged in the first-second internal space A1-2, and the second interval adjusting member 223 may be arranged in the third internal space A3. Therefore, the driving device (such as the second interval adjusting member 223) may be prevented from being exposed to chemicals, and corrosion caused by exposure to chemicals may be minimized.
[0245] Meanwhile, a pair of second shields 411 may be coupled to the third partition wall 130 .
[0246] The pair of second shielding members 411 may be arranged to face each other with respect to the second guide slit 131 and be made of a flexible material. The pair of second shielding members 411 may include permanent magnets having different magnetic properties.
[0247] For example, one second shield 411 may include an N-pole permanent magnet, and the other second shield 411 may include an S-pole permanent magnet.
[0248] The pair of second shielding members 411 may be coupled to each other by magnetic force to close the second guide slit 131. The second arm 221c may move along the second guide slit 131 while separating the pair of second shielding members 411. After the second arm 221c passes through the portion between the pair of second shielding members 411, the pair of second shielding members 411 separated from each other may be coupled to each other again by magnetic force. Therefore, the inflow or outflow of chemicals or chemical fumes through the second guide slit 131 may be suppressed.
[0249] The second clamper 221 may include a pair of second rollers 221 d coupled to the second arm 221 c so as to be rotatable about a rotation axis formed in the X direction.
[0250] For example, the second bracket 221e may be coupled to the second arm 221c, and the pair of second rollers 221d may be rotatably coupled to the second bracket 221e.
[0251] The pair of second rollers 221d may be arranged to be spaced apart from each other in the Z direction, and to be spaced apart from the second arm 221c in the Y direction. The pair of second shielding members 411 may be arranged between the pair of second rollers 221d. Therefore, the pair of second rollers 221d may assist in the reconnection operation of the pair of second shielding members 411, so that the area where the pair of second shielding members 411 are separated from each other may be minimized to the area where the second arm 221c is arranged.
[0252] The second arm 221 c may include a second tapered region 221 f that contacts the pair of second shields 411 .
[0253] The second tapered area 221f may have a vertical cross-sectional shape whose width in the Z direction increases as the distance from the pair of second rollers 221d in the Y direction increases. Therefore, the pair of second shielding members 411 may be in close contact with the second arm 221c to the greatest extent, and cooperate with the pair of second rollers 221d to minimize the opening area of the second guide slit 131.
[0254] The second bottle conveying member 252 may be coupled to the third partition wall 130 , and convey the second bottle holding member 220 in the Y direction.
[0255] The second bottle conveying member 252 may include a servo motor, but the present disclosure is not necessarily limited thereto.
[0256] The second bottle conveying member 252 may be disposed in the third inner space A3. Therefore, it is possible to prevent the driving device (such as the second bottle conveying member 252) from being exposed to chemicals, and minimize corrosion caused by exposure to chemicals.
[0257] Fig.18 is a perspective view of the cover separation / coupling module, Fig.19 yes Fig.18 An exploded perspective view of Fig. 20 and Fig.21 is a view for explaining the operating principle of the cover holding unit, Fig. 22 yes Fig. 20 A zoomed-in view of the Fig.23 yes Fig.21 A partial enlarged view of .

To this end, the cover holding unit 310 may include a first frame 311 , a plurality of grippers 312 , a second frame 313 , a plurality of links 314 , and a frame lifting part 315 , and may further include a plate member 318 and a plurality of elastic members 319 .
[0260] A plurality of holders 312 may be rotatably coupled to the first frame 311 so as to support a side surface of the cover C. As shown in FIG.
[0261] The second frame 313 may be disposed in a horizontal plate region of the first frame 311 , and conveyed in a vertical direction (ie, Z direction) by the frame lifting member 315 .
[0262] The number of the connecting rods 314 may be equal to the number of the clamps 312, for example, three. The connecting rods 314 may be rotatably coupled to the clamps 312 and the second frame 313. The vertical linear motion of the second frame 313 may be converted into the rotational motion of the clamp 312 through the connecting rods 314.
[0263] For example, Fig. 20 As shown, the plurality of clamps 312 rotate forward so that the clamping surfaces thereof move away from each other when the second frame 313 moves upward, so that the plurality of clamps 312 can be separated from the cover C. Fig.21 As shown, the plurality of clampers 312 are reversely rotated so that the clamping surfaces thereof move close to each other when the second frame 313 moves downward, so that the plurality of clampers 312 can hold the cover C.
[0264] The frame lifting member 315 may be coupled to the first frame 311 and convey the second frame 313 in the Z direction.
[0265] The frame lifting member 315 may include a pneumatic cylinder, but the present disclosure is not necessarily limited thereto. The frame lifting member 315 may include other lifting devices, such as a hydraulic cylinder.
[0266] The plate member 318 may be disposed below the first frame 311 and coupled to the first frame 311 so as to be vertically movable.
[0267] A plurality of elastic members 319 may be interposed between the first frame 311 and the plate member 318 and provide elastic force to the plate member 318 so that the plate member 318 is maintained in a horizontal state.
[0268] For example, the plurality of elastic members 319 may be arranged to be spaced apart from each other in the horizontal direction.
[0269] A lower surface of the plate member 318 may be disposed to face an upper surface of the cover C held by the plurality of clampers 312 .
[0270] Therefore, when the cap holding unit 310 moves upward or downward, it is possible to suppress the cap holding unit 310 from being damaged due to collision with the sampling bottle B or the cap C. Furthermore, even if the sampling bottle B is partially tilted, the state of the sampling bottle B can be changed to an upright state.
[0271] The cover rotating unit 320 may be installed on the lifting frame 340 and rotate the cover holding unit 310 (eg, the frame lifting member 315 ) around a rotation axis in the Z direction.
[0272] The cover rotating unit 320 may include a servo motor, but the present disclosure is not necessarily limited thereto.
[0273] The cover lifting unit 330 may transport the lifting frame 340 in a Z direction (ie, a vertical direction).
[0274] Therefore, the cover holding unit 310 together with the lifting frame 340 may also be conveyed in the Z direction by the cover lifting unit 330 .
[0275] In addition, the cap holding unit 310 may be moved downward by the cap lifting unit 330 and then hold the cap C. In addition, the cap holding unit 310 may be rotated and moved upward by the cap rotating unit 320 and the cap lifting unit 330 and separate the cap C from the sampling bottle B. The process of coupling the cap C to the sampling bottle B may be performed in reverse order.
[0276] The cover lifting unit 330 may be coupled to the upper surface of the housing 100. The frame lifting member 315, the cover rotating unit 320, and the cover lifting unit 330 may be arranged outside the housing 100. The frame lifting member 315 may extend to the first-second inner space A1-2 through a through hole formed in the upper wall of the housing 100. The driving device (such as the cover rotating unit 320 and the cover lifting unit 330) may be prevented from being exposed to chemical fumes, and corrosion caused by exposure to chemical fumes may be minimized.
[0277] The cover lifting unit 330 may include a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.
[0278] The lifting frame 340 may include a cylinder holder 341 configured to support the cylinder 316 constituting the frame lifting part 315 so that the cylinder 316 is rotatable.
[0279] For example, the frame lifting member 315 may include a cylinder 316 and a piston 317 .
[0280] The cylinder 316 may be coupled to the first frame 311 and the rotation shaft of the cover rotating unit 320 , and rotated by the cover rotating unit 320 .
[0281] The cylinder 316 may include a first cylinder region 316 a and a second cylinder region 316 b disposed above the first cylinder region 316 a .
[0282] A first cavity C1 may be formed in the first cylinder region 316 a , a second cavity C2 may be formed in the second cylinder region 316 b , and a piston 317 may be disposed in the first cavity C1 .
[0283] The piston 317 may include a first rod 317a passing through a lower wall of the cylinder 316 and coupled to the second frame 313, and a second rod 317b passing through a partition wall between the first cavity C1 and the second cavity C2 and extending to the second cavity C2. The first rod 317a may protrude from a lower surface of the piston 317, and the second rod 317b may protrude from an upper surface of the piston 317.
[0284] The piston 317 may be moved in a vertical direction by the fluid supplied into the first chamber C1 .
[0285] To this end, the cylinder retainer 341 may have a first fluid port 341a and a second fluid port 341b, and a fluid supply line (not shown) is connected to the first fluid port and the second fluid port. The first fluid port 341a and the second fluid port and 341b may extend to the inner circumferential surface of the cylinder retainer 341. The second cylinder region 316b may have a first through hole 316b-1 and a second through hole 316b-2 extending from the outer circumferential surface of the second cylinder region 316b to the second cavity C2. The first flow path 317a-1 may be formed in the piston 317 and connected to the first through hole 316b-1. The first flow path 317a-1 may extend to the outer circumferential surface of the upper end of the first rod 317a. The second flow path 317b-1 may be formed in the piston 317 and connected to the second through hole 316b-2. The second flow path 317b-1 may extend to the outer circumferential surface of the lower end of the second rod 317b.
[0286] The fluid injected through the first fluid port 341a may be sequentially supplied to the lower side of the first cavity C1 through the first through hole 316b-1, the first flow path 317a-1, and the first through flow path 317a-2. Thus, the piston 317 may move upward or downward.
[0287] The fluid injected through the second fluid port 341b may be sequentially supplied to the upper side of the first cavity C1 through the second through hole 316b-2, the second flow path 317b-1, and the second through flow path (317b-2). Therefore, the piston 317 may move downward.
[0288] An annular first groove 316 b - 3 and an annular second groove 316 b - 4 may be formed in the outer circumferential surface of the second cylinder region 316 b .
[0289] When the cylinder 316 rotates, the first groove 316b-3 and the second groove 316b-4 keep the first through hole 316b-1 and the second through hole 316b-2 connected to the first fluid port 341a and the second fluid port 341b, respectively.
[0290] However, the present disclosure is not necessarily limited thereto. The first groove 316 b - 3 and the second groove 316 b - 4 may be formed in the inner circumferential surface of the cylinder holder 341 .
[0291] The recess R may be formed in the lower and upper surfaces of the first cavity C1 and abut against the outer circumferential surface of the first rod 317 a or the second rod 317 b .
[0292] Therefore, even if the piston 317 reaches a height equal to or close to the height of the lower surface or the upper surface of the first cavity C1 , the first flow path 317 a - 1 or the second flow path 317 b - 1 may remain connected to the first cavity C1 .
[0293] The cover 350 may be coupled to the upper surface of the housing 100 and the cylinder holder 341, and provided in the form of a flexible pipe to surround a through hole formed in the housing 100. The frame lifting member 315 may be disposed in the cover 350. For example, the cover 350 may be a corrugated pipe.
[0294] Therefore, it is possible to suppress the chemical smoke from flowing in or out through the through hole of the housing 100 .
[0295] refer to Fig. 22 and Fig.23 , although the piston 317 moves upward or downward, the first through hole 316b-1 formed in the cylinder 316 can remain connected to the first flow path 317a-1 formed in the piston 317, and the second through hole 316b-2 formed in the cylinder 316 remains connected to the second flow path 317b-1 formed in the piston 317.
[0296] To this end, the stroke of the piston 317 (i.e., at the top dead center of the piston 317 (see Fig. 20 ) and bottom dead center (see Fig.21 ) between the first through hole 316b-1 and the first flow path 317a-1, and smaller than the sum of the outlet diameter d3 of the second through hole 316b-2 and the inlet diameter d4 of the second flow path 317b-1.
[0297] Fig.24 is a perspective view of the emission module. Fig.25 yes Fig.24 FIG. 26A is an exploded perspective view of the exhaust module, and FIG. 26A is a front view of the exhaust module.
[0298] refer to Fig.24 and Fig.25 , the exhaust module 500 may include a housing 510 having a single inlet port 510a or a plurality of inlet ports 510a formed in an upper surface thereof, and a discharge duct 520 and a supply duct 530 connected to the housing 510 .
[0299] As described above, the plurality of inlet ports 510a may correspond in number and arrangement to the plurality of sampling lines L1 , L2 , and L3 .
[0300] Chemicals collected in the inner space of the case 510 through the inlet port 510 a of the case 510 may be discharged to the outside of the housing 100 through the discharge pipe 520 , for example, to a chemical purification facility (not shown) or the like.
[0301] A diluent solution (eg, water) may be supplied to the inner space of the case 510 through the supply pipe 530. To this end, the supply pipe 530 may be connected to a diluent solution supply device (not shown) disposed outside the housing 100.
[0302] The exhaust duct 520 and the supply duct 530 may each be provided in the form of a flexible tube (flexible tube), and coupled to a through hole formed in the side wall of the housing 100 .
[0303] The second valve V2 (see Fig. 27 ) can be installed in the supply pipe 530, and the second valve V2 can be controlled by the control unit 710 (see Fig. 27 ) is controlled so as to operate together with the first valve V1 installed in the sampling pipelines L1, L2 and L3.
[0304] For example, the first valve V1 installed in the sampling lines L1, L2 and L3 may be opened for a predetermined time, so that the chemicals contained in the sampling lines L1, L2 and L3 are discharged to the discharge module 500 before the chemicals are filled into the sampling bottle B. In this case, the second valve V2 installed in the supply pipe 530 may also be opened. Therefore, after the chemicals contained in the sampling lines L1, L2 and L3 are discharged to the discharge module 500, the chemicals stored in the chemical storage tank may be filled into the sampling bottle B. The chemicals collected in the discharge module 500 may be mixed with a dilute solution and then discharged in a dilute state. At the same time, when a predetermined time has passed after the first valve V1 installed in the sampling lines L1, L2 and L3 is closed, the second valve V2 installed in the supply pipe 530 is closed, so that a cleaning operation of discharging the remaining chemicals in the discharge module 500 may be performed.
[0305] However, the present disclosure is not necessarily limited thereto. Depending on the chemical properties, the second valve V2 may be opened for a predetermined time after the first valve V1 is closed, or the second valve V2 may remain closed before and after the first valve V1 is closed. For example, when the chemical is an undiluted sulfuric acid solution, the mixture of the undiluted sulfuric acid solution and water generates excessive heat, which may adversely affect the entire device.
[0306] The conveying unit 600 may include a conveying device, such as a pneumatic cylinder 610 and a cover 620. However, the present disclosure is not necessarily limited thereto, and the conveying device may include a hydraulic cylinder, a motor, and the like.
[0307] The pneumatic cylinder 610 may be coupled to the third partition wall 130 and disposed in the third space (i.e., the third internal space A3). The piston rod 610a (i.e., the connecting member of the pneumatic cylinder 610) may extend through a through hole formed in the third partition wall 130 and be coupled to the housing 510 disposed in the first space (i.e., the first internal space, specifically, the first-second internal space A1-2). Therefore, the driving device (e.g., the pneumatic cylinder 610) may be prevented from being exposed to chemical fumes, and corrosion caused by exposure to chemical fumes may be minimized.
[0308] The cover 620 may prevent the chemical smoke from flowing in or out through the through-hole formed in the third partition wall 130 .
[0309] The cover 620 may be provided in the form of a flexible pipe, such as a corrugated pipe. Both opposite ends of the cover 620 may be coupled to the third partition wall 130 and the housing 510 , and the piston rod 610 a may extend through the cover 620 .
[0310] refer to Fig.26a , the inlet port 510 a of the cover case 510 may be arranged to be higher than a seating surface of the second bottle holding member 220 on which the sampling bottle B is seated.
[0311] For example, the height h1 from the upper surface of the housing 510 to the discharge ports of the sampling lines L1, L2, and L3 may be smaller than the height h2 from the placement surface of the second bottle holding part 220 to the discharge ports of the sampling lines L1, L2, and L3. The upper surface or inlet port 510a of the housing 510 may be arranged at substantially the same height as the opening of the upper end of the sampling bottle b.
[0312] Therefore, it is possible to minimize the chemical dripping distance from the discharge ports of the sampling lines L1 , L2 , and L3 to the inlet port 510 a of the housing 510 , and minimize the scattering of the chemical.
[0313] Figure 26b is a view showing a first modified example of the discharge module, Fig.26c and Fig.26d is a view showing a second modified example of the discharge module.
[0314] The configurations of the discharge module 500 and the sampling lines L1, L2, and L3 may be variously modified. Figure 26b , the sampling lines L1, L2, and L3 may be spaced apart from the discharge module 500 at a predetermined interval in a vertical direction. Therefore, the second bottle holding member 220 may freely move between the discharge module 500 and the sampling lines L1, L2, and L3.
[0315] In this case, the size of the inlet port 510a may be appropriately adjusted so that the chemicals discharged from the sampling lines L1, L2, and L3 may be introduced into the discharge module 500 without being scattered. Alternatively, the cover having the inlet port may be omitted. This configuration has the advantage that the drive unit may be omitted.
[0316] refer to Fig.26c , the sampling lines L1, L2, and L3 can be moved upward or downward by a separate driving unit. When the chemical is discharged, as the sampling lines L1, L2, and L3 move downward, this configuration can minimize the chemical dripping distance, thereby suppressing scattering.
[0317] In addition, if Fig.26d As shown, when the chemicals are completely discharged, the sampling lines L1 , L2 , and L3 may move upward, and the second bottle holding part 220 may move between the discharge module 500 and the sampling lines L1 , L2 , and L3 .
[0318] However, the present disclosure is not necessarily limited thereto. The discharge module 500 can move up or down in a state where the sampling lines L1, L2, and L3 are fixed. Alternatively, all the sampling lines L1, L2, and L3 and the discharge module 500 can move up or down. Alternatively, chemicals can be collected when the sampling lines L1, L2, and L3 and / or the discharge module 500 move forward or backward. Any configuration can be applied without restriction as long as the discharge module 500 can collect chemicals without limiting the movement of the second bottle holding component 220.
[0319] Embodiments have been described above, but these embodiments are merely illustrative and are not intended to limit the present disclosure. It will be appreciated by those skilled in the art that various modifications and changes not described above may be made without departing from the inherent features of the present disclosure. For example, the various constituent elements specifically described in the embodiments may be modified and subsequently executed. In addition, it should be understood that differences associated with modifications and applications are included within the scope of the present disclosure as defined by the appended claims.
