A part is divided and supplied to a plurality of second chemical storage tanks (5, 6).

As an example, the chemical sampling device 10 is connected to each chemical storage tank (3, 5, 6) through a plurality of sampling lines (L1, L2, L3), and each sampling line (L1, L2, L3) is a chemical An on-off valve (V) and a pump (P) may be provided to control the transfer.

According to another embodiment of the present invention, it is possible to supply a gas (for example, nitrogen or air) to the chemical source so that the chemical of the chemical source is transferred through the sampling line.

In the embodiment of the present invention, an example in which the sampling lines (L1, L2, L3) are connected to a chemical storage tank is described, but according to another embodiment of the present invention, the sampling line is a tank lorry, a drum, a bottle, a storage tank, and a pipe. It may be connected to all kinds of chemical supply sources for supplying, storing or transferring chemicals, such as, and the present invention is not limited or limited by the object or location to which the sampling line is connected.

Further, in the embodiment of the present invention, an example in which three sampling lines (L1, L2, L3) are connected to a chemical sampling device is described, but according to another embodiment of the present invention, two or less or four More than one sampling line may be connected, and the present invention is not limited or limited by the number of sampling lines.

According to a preferred embodiment of the present invention, the chemical sampling device 110 includes a case 1100 in which the container 20 to which the lid 22 is fastened is accommodated, and the container 20 and the lid ( 22) includes a lid detachable unit 1300 for selectively separating or fastening, and the sampling lines L1, L2, L3 include chemicals in the container 20 from which the lid 22 is separated from the inside of the case 1100. It is configured to supply.

As the container 20, chemicals may be accommodated, and various storage means having a lid 22 that can be selectively separated may be used, and the present invention is not limited or limited by the structure and shape of the container 20.

As an example, as the container 20, a sampling bottle in which a chemical can be accommodated may be used, and the lid 22 may be fastened or separated while rotating along a thread formed in the inlet of the container 20.

The case 1100 is formed to have an inner space 1102 in a linear shape (for example, in a straight shape), and the inner space 1102 of the case 1100 is an air space that is independently sealed by the partition wall 1101 ( It is divided into 1102a) and a work space 1102b.

Here, the waiting space 1102a means that the operator puts the container 20 inside the case 1100 from the outside of the case 1100, or the container 20 accommodated inside the case 1100 (for example, For example, when a container filled with chemicals) is taken out of the case 1100, it is defined as a space for temporarily waiting for the container 20.

In addition, in the embodiment of the present invention, the working space 1102b may be defined as a space for separating or combining the lid 22 from the container 20 and supplying chemicals to the interior of the container 20.

Preferably, the container 20 is configured to reciprocate the waiting space 1102a and the work space 1102b along a single linear path (eg, a linear movement path along the left and right directions) within the case 1100 .

Here, that the container 20 moves along a single linear path is defined as that the moving path of the container 20 is formed in a single linear shape.

In this way, by setting the moving path of the container 20 in the form of a single straight line inside the case 1100, the moving structure of the container 20 is simplified, and the moving path and the moving time of the container 20 are shortened. It is possible to obtain a favorable effect.

According to another embodiment of the present invention, it is possible to configure the container to move along a “L”-shaped movement path inside the case. For example, after the container entering the waiting space moves along the first linear movement path, the lower portion of the lid detachment unit and the second linear movement path intersecting (eg, perpendicular to) the first linear movement path It is also possible to configure to move to the lower part of the sampling line.

Alternatively, it is also possible to configure the container to move along a “C”-shaped movement path inside the case. For example, after a container entering the waiting space moves along a first linear movement path, it follows a second linear movement path that intersects (e.g., perpendicular to) the first linear movement path to the lower part of the lid removal unit. After moving, it may be configured to move to a lower portion of the sampling line along a third linear movement path that intersects (eg, perpendicular to) the second linear movement path.

In the case 1100, a first entrance that communicates with the waiting space 1102a is formed, and the first entrance is selectively opened and closed by a first door (1104 in FIG. 8). For example, the first door 1104 may be rotatably coupled to the case 1100 to open and close the first entrance in an opening and closing manner. According to another embodiment of the present invention, it is possible to configure the first door to open and close the first entrance in a sliding door manner.

The second door 1106 may open and close the second entrance in an opening or closing method, and the present invention is not limited or limited by the opening and closing method and structure of the second door 1106.

The second door 1106 is configured to open the second entrance when transferring the container 20 accommodated in the waiting space 1102a to the working space 1102b (or transferring from the working space to the waiting space), and the container ( When the lid 22 is separated or combined from 20), or when chemicals are supplied to the inside of the container 20, the second inlet is closed.

In this way, in the embodiment, the separation and bonding of the lid 22 to the container 20 and the chemical sampling process (injecting the chemical into the container) are performed in the working space 1102b that is independently sealed from the waiting space 1102a. By doing so, it is possible to obtain an advantageous effect of minimizing the chemical fume generated during the sampling process from being discharged to the outside through the atmospheric space 1102a.

In addition, an exhaust device (not shown) capable of discharging chemical fumes to the outside may be provided in the work space 1102b.

For reference, in the embodiment of the present invention, the separation and coupling of the lid 22 to the container 20 in the working space 1102b, and the supply of chemicals are all described, but other embodiments of the present invention According to the case, the working space of the case is divided into a first working space and a second working space that are independently sealed, and the process of separating or combining the lid from the container is performed in the first working space, and chemicals are supplied to the inside of the container. It is also possible to configure the process to be performed in the second working space.

A holder module 1110 for accommodating and supporting the container 20 is provided inside the case 1100.

The holder module 1110 may be formed in various structures capable of gripping and supporting the container 20 in the case 1100, and the present invention is not limited or limited by the structure of the holder module 1110.

As an example, the holder module 1110 includes a bottom portion 1112 supporting the bottom surface of the container 20, and a first side support portion extending upward to one side of the bottom portion 1112 to support the side surface of the container 20 (1114), it may include a second side support portion 1116 extending upwardly to the other side of the bottom portion 1112 to face the first side support portion 1114 to support the other side of the container 20, and , The first side support 1114 and the second side support 1116 cooperatively form a storage space in which the container 20 is accommodated.

Preferably, the second side support portion 1116 is formed to have a relatively shorter height (height along the vertical direction) than the first side support portion 1114. In this way, by forming the height of the second side support part 1116 to be shorter than that of the first side support part 1114, a free space in which the container 20 can enter can be formed on the top of the second side support part 1116. Therefore, it is possible to store the container 20 in the storage space by tilting the container 20 through the free space. In addition, the operator can easily grip the circumferential surface of the container 20 exposed through the free space.

According to a preferred embodiment of the present invention, the chemical sampling device 110 includes a transfer unit (not shown) for transferring the holder module 1110 inside the case 1100.

For example, the transfer unit may be configured to reciprocate and linearly transfer the holder module 1110 from the waiting space 1102a to the work space 1102b along a horizontal direction (left and right directions based on FIG. 2 ).

More specifically, the transfer unit transfers the holder module 1110 (the holder module in which the container is accommodated) disposed in the waiting space 1102a through the lower portion of the lid detachable unit 1300 provided in the working space 1102b to the sampling line L1, After transferring to the lower part of L2 and L3, and after the chemical is filled in the container 20, the holder module 1110 disposed in the working space 1102b is transferred to the waiting space 1102a through the lower part of the lid detachable unit 1300. To transfer.

The transfer unit (not shown) may be formed in various structures capable of transferring the holder module 1110, and the present invention is not limited or limited by the structure and operation method of the transfer unit.

As an example, the transfer unit may be configured to linearly move the holder module 1110 by a lead screw rotating by a driving force to a driving motor or other conventional linear motion system.

Preferably, the transfer unit may be mounted outside the case 1100 and configured to transfer the holder module 1110 using magnetic force (or electromagnetic force) or the like in a structurally separated state from the holder module 1110. In this way, by structurally separating the transfer unit and the holder module 1110, the holder module 1110 disposed inside the case 1100 and the transfer unit provided outside the case 1100 are structurally connected. Since it is not necessary to form the slot for the case 1100 through the wall surface of the case 1100, it is possible to obtain an advantageous effect of suppressing the fume generated during the chemical sampling process from being exposed to the outside through the slot.

The lid detachable unit 1300 is provided on the work space 1102b and is configured to separate the cap from the container 20 transferred to the work space 1102b or fasten the cap to the container 20.

More specifically, the gripping portion 1310 includes a plurality of grippers 1311 supporting the side surfaces of the lid 22 of the container 20, a fixing frame 1312 to which the grippers 1311 are rotatably coupled, and an elevating frame ( 1313), one end is rotatably connected to the gripper 1311, and the other end is a connecting link 1314 rotatably connected to the first elevating frame 1313, the first elevating frame 1313 is transported along the vertical direction It may include a frame lifting unit 1315.

For example, when a plurality of grippers 1311 are rotated clockwise (refer to FIG. 7) based on the connecting link, the gripping surfaces of each gripper 1311 (parts that grip the sides of the lid) are moved away from each other. By moving, each gripper 1311 can be separated from the lid 22 (releasing the grip state). On the other hand, when the plurality of grippers 1311 rotate in a counterclockwise direction (refer to FIG. 7) based on the connecting link, the gripping surfaces of each gripper 1311 (parts gripping the sides of the lid) are approached to each other. By moving, the sides of the lid 22 can be gripped cooperatively by the gripper 1311.

The frame elevating part 1315 may be elevated by a pneumatic cylinder, but is not limited thereto, and may include other elevating means such as a hydraulic cylinder.

The rotating part 1320 is provided to rotate the frame lifting part 1315 around a vertical line (a vertical axis of rotation), and the lifting part 1330 is provided to transport the second lifting frame connected with the rotating part in the vertical direction.

With this structure, after the gripping part 1310 is lowered by the lifting part 1330, the lid 22 can be gripped, and rotation by the rotation part 1320 (first direction rotation) and the lifting part 1330 The lid 22 may be separated from the container 20 by rising by ). Conversely, the process of fastening the lid 22 to the container 20 may be performed by rotation by the rotating part 1320 (rotation in the second direction) and lowering by the lifting part.

For example, the rotating part 1320 may include a servo motor. In some cases, it is also possible for the rotating unit to include other driving means.

The lifting unit 1330 may include a pneumatic cylinder, but is not limited thereto.

The lifting part 1330 may be coupled to the upper surface of the case 1100, and the frame lifting part 1315, the rotating part 1320 and the lifting part 1330 may be disposed outside the case 1100, and the frame lifting part The part 1315 may extend into the working space 1102b through a through hole (not shown) formed in the upper wall of the case 1100. Therefore, it is possible to minimize chemical exposure and corrosion caused by driving devices such as the rotating part 1320 and the lifting part 1330.

In addition, access of the chemical fume through a through hole (not shown) formed in the case 1100 may be blocked by the first cover member (1340 in FIG. 2 ). For example, the first cover member 1340 may be formed as a corrugated pipe that can be stretched, and both ends of the first cover member 1340 are elevating to rotatably support the upper surface of the case 1100 and the frame elevating portion 1315 It may be coupled to the frame 1331, and the frame lifting unit 1315 may extend through the first cover member 1340. Accordingly, it is possible to suppress the entry of the chemical or chemical fume through the through hole of the case 1100.

According to a preferred embodiment of the present invention, a constraining member 1210 for selectively restraining the rotation (rotation around a vertical axis) of the container 20 with respect to the lid removal unit 1300 at the lower portion of the lid removal unit 1300 ,1220) is provided.

As an example, a plurality of constraining members 1210 and 1220 may be provided so as to be able to move linearly in a direction approaching and spaced apart from the container 20. At this time, the number and arrangement intervals of the constraining members 1210 and 1220 may be variously changed according to required conditions and design specifications.

When the container 20 accommodated in the holder module 1110 is located under the lid detachable unit 1300 (lid detachable position), the plurality of restraining members 1210 and 1220 approach the circumference of the container 20 By moving to and cooperatively pressing the circumference of the container 20, the rotation of the container 20 is restrained. On the other hand, after the separation or fastening of the lid 22 is completed, the restraint members 1210 and 1220 move in a direction away from the circumference of the container 20, thereby releasing the restraint by the restraining members 1210 and 1220.

According to a preferred embodiment of the present invention, the chemical sampling device 110 is a drain module (not shown) for collecting chemicals remaining in the sampling lines L1, L2, L3 before supplying the chemicals to the container 20. It may include.

The drain module is provided to discharge contaminated chemicals remaining in the sampling lines L1, L2, L3 before supplying the chemicals to the container 20 from the sampling lines L1, L2, L3.

That is, the chemicals filled in the sampling lines L1, L2, and L3 are likely to stagnate after a certain period of time to generate sediment or to be contaminated through an open discharge port.

However, in the embodiment, the chemicals remaining in the sampling lines L1, L2, and L3 are collected by the drain module before supplying the chemicals to the container 20, so that the high purity chemicals that are not contaminated are stored in the container 20. ), it is possible to obtain an advantageous effect of improving the reliability of chemical contamination analysis.

That is, in the chemical sampling apparatus, there is a problem in that the chemical leaks unintentionally from the sampling line even though the supply of the chemical is stopped. More specifically, after the chemical sampling process is completed, a small amount of chemical remains at the outlet end of the sampling line. As the chemical remaining at the outlet end of the sampling line falls one or two drops, the entire work space is directly exposed to the chemical. There is a problem.

In addition, even when a valve that controls the supply of chemicals by the sampling line fails, there is a problem in that chemicals are unintentionally discharged from the sampling line and the work space is exposed to the chemicals.

However, in the embodiment, after the chemical sampling process is completed (or before the chemical sampling process), the outlet ends of the sampling lines L1, L2, L3 are sealed by the end cap member 1400, thereby preventing chemical leakage. In addition, it is possible to obtain an advantageous effect of suppressing direct exposure of the chemicals dropped or discharged from the sampling lines L1, L2, and L3 to the work space 1102b.

Moreover, since the outlet ends of the sampling lines L1, L2, L3 can be sealedly accommodated inside the end cap member 1400, the sampling line L1, It is possible to obtain an advantageous effect of minimizing contamination and damage of L2, L3).

The end cap member 1400 may be formed in a variety of structures capable of sealing the outlet ends of the sampling lines L1, L2, L3 from which chemicals are discharged, and the shape and structure of the end cap member 1400 are required conditions. And it can be variously changed according to the design specification.

Here, the end cap member 1400 sealing the exit ends of the sampling lines L1, L2, L3 means that the exit ends of the sampling lines L1, L2, L3 are outside (for example, the work space). It is defined as being blocked by the end cap member 1400 without being exposed.

As an example, three end cap members 1400 may be provided with three sampling lines L1, L2, and L3 respectively corresponding to each other, and the number and arrangement structure of the end cap members 1400 are sampling lines L1 and L2. It can be appropriately changed according to the number and arrangement of L3).

The moving unit 1500 is provided to selectively move the end cap member 1400 so that the end cap member 1400 is located in a first position sealing the outlet end or a second position opening the outlet end.

Here, that the end cap member 1400 is positioned at the first position means that the end cap member 1400 is positioned to block (close) the exit ends of the sampling lines L1, L2, L3 as shown in FIG. 4. It is defined, and that the end cap member 1400 is positioned at the second position means that the end cap member 1400 is positioned to expose (open) the outlet ends of the sampling lines L1, L2, L3, as shown in FIG. 11. It is defined as doing.

The end cap member 1400 may be configured to move from the first position to the second position in various ways according to required conditions and design specifications.

For example, the moving unit 1500 is configured to rotate the end cap member 1400 from a first position to a second position (or from a second position to a first position).

More specifically, the moving unit 1500 includes a driving unit 1510 providing a driving force, and an end cap member 1400 being supported and rotating by the driving unit 1510, and removing the end cap member 1400 at the first position. It includes a rotating member 1520 to move to two positions.

As the driving unit 1510, a cylinder (for example, a pneumatic cylinder or a hydraulic cylinder), a motor, etc. that can provide driving force may be used, and the present invention is not limited or limited by the type and structure of the driving unit 1510. .

The rotating member 1520 is formed to have an approximately “L” shape, one end (top) is connected to the driving unit 1510, and the end cap member 1400 is supported at the other end.

Preferably, the rotating member 1520 horizontally rotates about an axis along a vertical direction and is configured to move the end cap member 1400 from the first position to the second position. In this way, by moving the end cap member 1400 from the first position to the second position while the rotating member 1520 horizontally rotates about the axis along the vertical direction, the arrangement and operation of the rotating member 1520 Since the required space can be minimized, advantageous effects of improving space utilization and design freedom can be obtained.

According to another embodiment of the present invention, it is possible to configure the rotating member to rotate about an axis along a vertical direction or an axis along another direction, and to move the end cap member from the first position to the second position. According to another embodiment of the present invention, it is also possible to configure the end cap member to move linearly (horizontal movement) from the first position to the second position.

According to a preferred embodiment of the present invention, the sampling lines L1, L2, L3 are supported by the holder member 1420.

For example, the sampling lines L1, L2, and L3 are supported by a holder member 1420 fixed to the case 1100.

A cover member (not shown) in the form of a corrugated pipe that can be stretched may be provided between the upper part of the holder member 1420 and the inner surface (the upper inner surface) of the case 1100, and the sampling lines L1, L2, and L3 are It is arranged to pass through the interior. Accordingly, it is possible to obtain an advantageous effect of minimizing exposure of fumes through a through hole (not shown) formed in the case 1100 to pass the sampling lines L1, L2, and L3.

It is disposed to be in close contact with the lower portion of the holder member 1420 so as to surround it.

As an example, the receiving groove 1402 is recessed in the upper surface of the end cap member 1400, and the outlet ends of the sampling lines L1, L2, L3 at the first position are spaced apart from the inner wall surface of the receiving groove 1402. It is accommodated in the interior of the receiving groove 1402.

In this way, by allowing the outlet ends of the sampling lines L1, L2, L3 to be accommodated in the receiving groove 1402 apart from the inner wall surface of the receiving groove 1402, the sampling lines L1, L2, L3 It is possible to obtain an advantageous effect of preventing contamination of the outlet end due to contact between the outlet end of the end cap member 1400 and the end cap member 1400.

In addition, when the sealing work of the outlet end of the sampling line is performed by the operator's manual work, there is a problem that the operator is directly exposed to the chemical leaked into the sealing member sealing the outlet end. Since the sealing operation of the exit ends of the sampling lines L1, L2, and L3 by the end cap member 1400 can be automatically performed within the working space 1102b without directly contacting the 1400, the end cap member It is possible to obtain an advantageous effect of preventing workers from being exposed to chemicals leaking to (1400).

Moreover, the end cap member 1400 does not directly contact the sampling lines L1, L2, L3, but is in close contact with the lower portion of the holder member 1420, and seals the outlet ends of the sampling lines L1, L2, L3. , It is possible to obtain an advantageous effect of more stably maintaining the arrangement state of the end cap member 1400 with respect to the sampling lines L1, L2, L3 and the state in which the outlet end is sealed.

In addition, a protrusion 1404 is formed on the upper surface of the end cap member 1400 facing the lower portion of the holder member 1420, and a depression 1424 corresponding to the protrusion 1404 is formed on the bottom surface of the holder member 1420. Can be formed.

In this way, by allowing the protrusion 1404 formed on the upper surface of the end cap member 1400 to be accommodated in the depression 1424 formed on the bottom surface of the holder member 1420, a double sealing structure with the receiving groove 1402 is formed. Since it can be formed, it is possible to obtain an advantageous effect of more effectively suppressing leakage of chemicals leaking into the receiving groove 1402 to the outside through the between the holder member 1420 and the end cap member 1400.

In addition, according to a preferred embodiment of the present invention, the receiving groove 1402 may be provided with a detection sensor 1430 for detecting a chemical leaked from the outlet end of the sampling line (L1, L2, L3).

For example, the second moving unit 2700 is connected to the second driving unit 2710 and the drain module 2120, and is linearly moved in the horizontal direction by the second driving unit 2710 to provide the drain module 2120. It includes a second moving member 2720 for moving to the 3rd position or the 4th position.

The second moving member 2720 is provided to be linearly moved in a horizontal direction, and the second driving part 2710 is provided to provide a driving force for linearly moving the second moving member 2720.

Various driving means capable of providing a driving force required for linear movement of the second moving member 2720 may be used as the second driving unit 2710. For example, a conventional pneumatic (or hydraulic) cylinder or motor may be used as the second driving unit 2710. According to another embodiment of the present invention, it is also possible to configure the second moving member to move linearly by a lead screw rotating by a driving force to the drive motor or other conventional linear motion system. According to another embodiment of the present invention, the second moving unit may be configured to rotate the drain module from the third position to the fourth position (for example, to rotate the drain module based on the vertical axis direction).

The second moving member 2720 may be formed as a single member capable of linear movement by a second driving unit 2710 mounted on the outside of the work space, or may be configured by assembling a plurality of members, and the second moving member 2720 The present invention is not limited or limited by its structure and form.

The second moving unit 2700 is controlled to operate in connection with the first moving unit 2600. More specifically, when the drain module 2120 is moved to the third position by the second moving unit 2700 while the holder member 2420 is moved to the second position, the first moving unit 2600 is The member 2420 is moved from the second position to the first position. When the holder member 2420 moves to the first position while the drain module 2120 is moved to the third position, the entrance port 2123 is sealed by the holder member 2420.

According to a preferred embodiment of the present invention, the chemical sampling device 210 includes an end cap member 2400 provided to seal the outlet ends of the sampling lines L1, L2, and L3, and an end cap member 2400 And a third moving unit 2500 selectively moving the end cap member 2400 to be positioned at a fifth position sealing the outlet end or a sixth position opening the outlet end.

The end cap member 2400 and the third moving unit 2500 are used to suppress leakage of chemicals through the sampling lines L1, L2, and L3, and to minimize contamination and damage of the sampling lines L1, L2, and L3. It is provided to configure the chemical sampling device 210.

That is, in the chemical sampling apparatus 210, there is a problem in that the chemical leaks unintentionally from the sampling lines L1, L2, and L3 even though the supply of the chemical is stopped. More specifically, after the chemical sampling process is completed, a small amount of chemical remains at the exit ends of the sampling lines (L1, L2, L3), but one or two chemicals remain at the exit ends of the sampling lines (L1, L2, L3). As they fall drop by drop, there is a problem in that the entire work space is directly exposed to the chemical.

In addition, even if a valve that controls the chemical supply by the sampling lines (L1, L2, L3) fails, chemicals are unintentionally discharged from the sampling lines (L1, L2, L3), exposing the work space to the chemicals. There is a problem.

However, in the embodiment, after the chemical sampling process is completed (or before the chemical sampling process), the outlet ends of the sampling lines L1, L2, L3 are sealed by the end cap member 2400, thereby preventing chemical leakage. It is possible to obtain an advantageous effect of suppressing and suppressing direct exposure of the chemicals dropped or discharged from the sampling lines L1, L2 and L3 to the working space 2102b.

Moreover, since the outlet ends of the sampling lines L1, L2, and L3 can be sealedly accommodated inside the end cap member 2400, the sampling line L1, due to contact with pollutants and peripheral equipment contained in the outside air, etc. It is possible to obtain an advantageous effect of minimizing contamination and damage of L2, L3).

The end cap member 2400 may be formed in various structures capable of sealing the outlet ends of the sampling lines L1, L2, L3 from which the chemical is discharged, and the shape and structure of the end cap member 2400 are required conditions. And it can be variously changed according to the design specification.

Here, the end cap member 2400 sealing the exit ends of the sampling lines L1, L2, L3 means that the exit ends of the sampling lines L1, L2, L3 are outside (for example, the work space). It is defined as being blocked by the end cap member 2400 without being exposed.

For example, the end cap member 2400 may be provided with three sampling lines L1, L2, and L3 corresponding to each of the three, and the number and arrangement structure of the end cap member 2400 is the sampling lines L1 and L2. It can be appropriately changed according to the number and arrangement of L3).

The third moving unit 2500 is provided to selectively move the end cap member 2400 such that the end cap member 2400 is located at a fifth position sealing the outlet end or a sixth position opening the exit end.

Here, that the end cap member 2400 is positioned at the fifth position means that the end cap member 2400 is positioned to block (close) the exit ends of the sampling lines L1, L2, L3, as shown in FIG. It is defined, and that the end cap member 2400 is positioned at the sixth position means that the end cap member 2400 is positioned to expose (open) the outlet ends of the sampling lines L1, L2, L3, as shown in FIG. It is defined as doing.

The end cap member 2400 may be configured to move from the fifth position to the sixth position in various ways according to required conditions and design specifications.

For example, the third moving unit 2500 is configured to rotate and move the end cap member 2400 from a fifth position to a sixth position (or a sixth position to a fifth position).

More specifically, the third moving unit 2500 supports the third driving unit 2510 and the end cap member 2400 and horizontally rotates by the third driving unit around an axis along the vertical direction, and the end cap member ( It includes a third moving member 2520 for moving 2400) to the fifth position or the sixth position.

As the third driving unit 2510, various driving means capable of providing a driving force required for rotational movement of the third moving member 2520 may be used. For example, a conventional pneumatic (or hydraulic) cylinder or motor may be used as the third driving unit 2510, and the present invention is not limited or limited by the type and structure of the third driving unit 2510.

The third moving member 2520 is formed to have an approximately “L” shape, one end (top) is connected to the third driving unit 2510, and the end cap member 2400 is supported at the other end.

Preferably, the third moving member 2520 horizontally rotates about an axis along the vertical direction and is configured to move the end cap member 2400 from the fifth position to the sixth position. In this way, the third moving member 2520 horizontally rotates about an axis along the vertical direction and moves the end cap member 2400 from the fifth position to the sixth position. Since the space required for arrangement and operation can be minimized, advantageous effects of improving space utilization and design freedom can be obtained.

According to another embodiment of the present invention, it is possible to configure the third moving member to rotate around an axis along a horizontal direction or an axis along another direction, and to move the end cap member from the fifth position to the sixth position. Do. According to another embodiment of the present invention, it is also possible to configure the end cap member to move linearly (horizontal movement) from the fifth position to the sixth position.

The third moving unit 2500 is controlled to operate in connection with the first moving unit 2600 and the second moving unit 2700. More specifically, when the drain module 2120 moves to the fourth position while the holder member 2420 is moved to the second position, the end cap member 2400 is moved to the fifth position by the third moving unit 2500. When the holder member 2420 is moved to the position and moved from the second position to the first position by the first moving unit 2600, the exit of the sampling lines L1, L2, L3 by the end cap member 2400 The stage is sealed.

Preferably, the outlet ends of the sampling lines (L1, L2, L3) pass through the holder member 2420 and are exposed to the lower portion of the holder member 2420, and at the fifth position, the end cap member 2400 is around the exit end. It is disposed to be in close contact with the lower portion of the holder member 2420 so as to surround it.

As an example, the receiving groove 2402 is recessed in the upper surface of the end cap member 2400, and the outlet ends of the sampling lines L1, L2, L3 at the fifth position are spaced apart from the inner wall surface of the receiving groove 2402. It is accommodated in the interior of the receiving groove 2402.

In this way, by allowing the outlet ends of the sampling lines L1, L2, L3 to be accommodated in the receiving groove 2402 apart from the inner wall surface of the receiving groove 2402, the sampling lines L1, L2, L3 It is possible to obtain an advantageous effect of preventing contamination of the outlet end due to contact between the outlet end of the end cap member 2400 and the end cap member 2400.

In addition, when the sealing work of the outlet end of the sampling line (L1, L2, L3) is performed by manual operation of the worker, there is a problem in that the worker is exposed to the chemical leaked to the sealing member that seals the outlet end. In the case, the operator does not directly contact the end cap member 2400, and the sealing work of the exit ends of the sampling lines L1, L2, L3 by the end cap member 2400 is automatically performed within the working space 2102b. Therefore, it is possible to obtain an advantageous effect of preventing a worker from being exposed to chemicals leaking out to the end cap member 2400 in advance.

Moreover, the end cap member 2400 does not directly contact the sampling lines L1, L2, L3, but is in close contact with the lower portion of the holder member 2420, and seals the outlet ends of the sampling lines L1, L2, L3. , It is possible to obtain an advantageous effect of more stably maintaining the arrangement state of the end cap member 2400 with respect to the sampling lines L1, L2, L3 and the state in which the outlet end is sealed.

In addition, a protrusion 2404 is formed on the upper surface of the end cap member 2400 facing the lower portion of the holder member 2420, and a depression 2424 corresponding to the protrusion 2404 is formed on the bottom surface of the holder member 2420. Can be formed.

In this way, by allowing the protrusion 2404 formed on the upper surface of the end cap member 2400 to be accommodated in the depression 2424 formed on the bottom surface of the holder member 2420, a double sealing structure with the receiving groove 2402 is formed. Since it can be formed, it is possible to obtain an advantageous effect of more effectively suppressing leakage of chemicals leaking into the receiving groove 2402 to the outside through the between the holder member 2420 and the end cap member 2400.

In addition, according to a preferred embodiment of the present invention, the receiving groove 2402 may be provided with a detection sensor 2430 for detecting a chemical leaked from the outlet end of the sampling line (L1, L2, L3).

As the detection sensor 2430, a conventional sensor capable of detecting chemicals (eg, an optical sensor, an infrared sensor, and a capacitance sensor) may be used, and the present invention may be limited by the type and sensing method of the detection sensor 2430 It is not limited.

In addition, when a chemical leak is detected by the detection sensor 2430, the control unit (not shown) may generate an alarm signal for recognizing the chemical leak situation to the worker.

Here, the alarm signal may include at least one of an audible alarm signal by a conventional sound means and a visual alarm signal by a normal warning light. An alarm signal can be used.

In addition, according to a preferred embodiment of the present invention, a sealing member 2440 may be disposed between the holder member 2420 and the end cap member 2400.

Preferably, the sealing member 2440 is provided under the holder member 2420, and the upper portion of the end cap member 2400 or the drain module 2120 as the holder member 2420 descends (moves to the first position). It can be used in common to pressurize.

Preferably, when the holder member 2420 moves to the first position, the sealing member 2440 is pressed between the holder member 2420 and the end cap member 2400.

In this way, when the holder member 2420 is lowered (reached to the lowered position), the sealing member 2440 is pressed by the holder member 2420, so that between the holder member 2420 and the end cap member 2400 Since the gap can be more effectively sealed, an advantageous effect of minimizing leakage of chemicals to the outside of the end cap member 2400 can be obtained.

Hereinafter, a chemical sampling process by the chemical sampling device 210 according to an embodiment of the present invention will be described.

For reference, the chemical sampling device 310 according to the embodiment of the present invention is mounted on the chemical storage facility 31 and can be used to sample chemicals at key locations such as tank lorries, drums, bottles, storage tanks, and pipes. In addition, the present invention is not limited or limited by the type and location of the object to which the chemical sampling device 310 is mounted.

According to a preferred embodiment of the present invention, the chemical sampling device 310 includes the container 20 and the lid 22 in the interior of the case 3100 (for example, the working space of the first space 3102). It includes a lid detachable unit 3300 that is selectively separated or fastened, and the sampling lines (L1, L2, L3) are configured to supply chemicals to the container 20 from which the lid 22 is separated from the inside of the case 3100 do.

As the container 20, chemicals may be accommodated, and various storage means having a lid 22 that can be selectively separated may be used, and the present invention is not limited or limited by the structure and shape of the container 20. .

As an example, as the container 20, a sampling bottle capable of accommodating a chemical may be used, and the lid 22 may be fastened or separated while rotating along a thread formed in the inlet of the container 20.

The case 3100 is formed to have a linear (for example, straight) inner space, and the inner space of the case 3100 is a first space 3102 and a first space that are independently sealed by the partition wall part 3101. It is divided into two spaces 3103.

Here, that the first space 3102 and the second space 3103 are independently sealed means that the first space 3102 and the second space 3103 are spatially separated, so that the first space 3102 and the second space 3102 are separated. Air flow between the spaces 3103 is defined as being blocked.

The structure and shape of the first space 3102 and the second space 3103 divided by the partition wall portion 3101 can be variously changed according to required conditions and design specifications. The present invention is not limited or limited by the structure and shape of the two-space 3103.

For example, the partition wall portion 3101 is connected to an end of the first partition wall 3101a and the first partition wall 3101a horizontally partitioning the inner space of the case 3100 and vertically defines the inner space of the case 3100. It includes a second partition wall (3101b) divided into. The first space 3102 divided by the first partition wall 3101a and the second partition wall 3101b may be formed in an approximately rectangular cross-sectional shape, and the second space 3103 is formed in an approximately "L"-shaped cross-sectional shape.

Here, that the container 20 moves along a single linear path is defined as that the moving path of the container 20 is formed in a single linear shape.

In this way, by setting the moving path of the container 20 in a single linear shape inside the case 3100, the moving structure of the container 20 is simplified, and the moving path and the moving time of the container 20 are shortened. It is possible to obtain a favorable effect.

According to another embodiment of the present invention, it is possible to configure the container to move along a “L”-shaped movement path inside the case. For example, after the container entering the waiting space moves along the first linear movement path, the lower portion of the lid detachment unit and the second linear movement path intersecting (eg, perpendicular to) the first linear movement path It is also possible to configure to move to the lower part of the sampling line.

Alternatively, it is also possible to configure the container to move along a “C”-shaped movement path inside the case. For example, after a container entering the waiting space moves along a first linear movement path, it follows a second linear movement path that intersects (e.g., perpendicular to) the first linear movement path to the lower part of the lid removal unit. After moving, it may be configured to move to a lower portion of the sampling line along a third linear movement path that intersects (eg, perpendicular to) the second linear movement path.

In the case 3100, a first entrance to communicate with the waiting space 3102a is formed, and the first entrance is selectively opened and closed by a first door (3104 in FIG. 34). For example, the first door 3104 may be rotatably coupled to the case 3100 to open and close the first entrance in an opening and closing manner. According to another embodiment of the present invention, it is possible to configure the first door to open and close the first entrance in a sliding door manner.

A second entrance through which the container 20 can enter and exit is formed in the partition wall portion 3101 (the second partition wall), and the second entrance is selectively opened and closed by the second door 3106. The second door 3106 may open and close the second entrance in an opening or closing method, and the present invention is not limited or limited by the opening and closing method and structure of the second door 3106.

The second door 3106 is configured to open the second entrance when transferring the container 20 accommodated in the waiting space 3102a to the working space 3102b (or transferring from the working space to the waiting space), and the container ( When the lid 22) is separated or combined from 20), or when chemicals are supplied to the inside of the container 20, the second inlet is closed.

As such, the embodiment is the separation and bonding of the lid 22 for the container 20 in the working space 3102b, which is independently sealed from the waiting space 3102a, and a chemical sampling process (chemical injection into the three containers) By doing this, it is possible to obtain an advantageous effect of minimizing the chemical fume generated during the sampling process from being discharged to the outside through the air space 3102a.

Preferably, the second side support part 3116 is formed to have a relatively shorter height (height along the vertical direction) than the first side support part 3114. In this way, by forming the height of the second side support part 3116 to be shorter than that of the first side support part 3114, a free space in which the container 20 can enter can be formed on the top of the second side support part 3116. Therefore, it is possible to store the container 20 in the storage space by tilting the container 20 through the free space. In addition, the operator can easily grip the circumferential surface of the container 20 exposed through the free space.

Here, that the end cap member 3400 is positioned at the fifth position is defined as being positioned so that the end cap member 3400 blocks (closes) the exit ends of the sampling lines L1, L2, L3, and That the cap member 3400 is positioned at the sixth position is defined as being positioned so that the end cap member 3400 exposes (opens) the outlet ends of the sampling lines L1, L2, and L3.

The end cap member 3400 may be configured to move from the fifth position to the sixth position in various ways according to required conditions and design specifications.

For example, the third moving unit 3500 is configured to rotate and move the end cap member 3400 from a fifth position to a sixth position (or from a sixth position to a fifth position).

More specifically, the third moving unit 3500 supports the third driving unit 3510 and the end cap member 3400 and horizontally rotates by the third driving unit around an axis along the vertical direction, and the end cap member ( And a third moving member 3520 for moving the 3400 to the fifth position or the sixth position.

As the third driving unit 3510, various driving means capable of providing a driving force required for rotational movement of the third moving member 3520 may be used. For example, a conventional pneumatic (or hydraulic) cylinder or motor may be used as the third driving unit 3510, and the present invention is not limited or limited by the type and structure of the third driving unit 3510.

The third moving member 3520 is formed to have an approximately “L” shape, one end (top) is connected to the third driving unit 3510, and the end cap member 3400 is supported at the other end.

Preferably, the third moving member 3520 horizontally rotates about an axis along the vertical direction and is configured to move the end cap member 3400 from the fifth position to the sixth position. In this way, the third moving member 3520 horizontally rotates about an axis along the vertical direction and moves the end cap member 3400 from the fifth position to the sixth position. Since the space required for arrangement and operation can be minimized, advantageous effects of improving space utilization and design freedom can be obtained.

According to another embodiment of the present invention, it is possible to configure the third moving member to rotate around an axis along a horizontal direction or an axis along another direction, and to move the end cap member from the fifth position to the sixth position. Do. According to another embodiment of the present invention, it is also possible to configure the end cap member to move linearly (horizontal movement) from the fifth position to the sixth position.

The third moving unit 3500 is controlled to operate in connection with the first moving unit 3600 and the second moving unit 3700. More specifically, when the drain module 3120 moves to the fourth position while the holder member 3420 is moved to the second position, the end cap member 3400 is moved to the fifth position by the third moving unit 3500. When the holder member 3420 is moved from the second position to the first position by the first moving unit 3600, the exit of the sampling lines L1, L2, L3 by the end cap member 3400 The stage is sealed.

Preferably, the outlet ends of the sampling lines L1, L2, L3 pass through the holder member 3420 and are exposed to the lower portion of the holder member 3420, and at the fifth position, the end cap member 3400 is around the outlet end. It is disposed to be in close contact with the lower portion of the holder member 3420 so as to surround it.

For example, the receiving groove 3402 is recessed in the upper surface of the end cap member 3400, and the outlet ends of the sampling lines L1, L2, L3 at the fifth position are spaced apart from the inner wall surface of the receiving groove 3402. It is accommodated in the interior of the receiving groove 3402.

In this way, by allowing the outlet ends of the sampling lines L1, L2, L3 to be accommodated in the receiving groove 3402 to be spaced apart from the inner wall surface of the receiving groove 3402, the sampling lines L1, L2, L3 It is possible to obtain an advantageous effect of preventing contamination of the outlet end due to contact between the outlet end and the end cap member 3400 of the.

In addition, when the sealing work of the outlet end of the sampling line (L1, L2, L3) is performed by manual operation of the worker, there is a problem in that the worker is exposed to the chemical leaked to the sealing member that seals the outlet end. In the case, the operator does not directly contact the end cap member 3400, and the sealing of the exit ends of the sampling lines L1, L2, L3 by the end cap member 3400 is automatically performed within the working space 3102b. Therefore, it is possible to obtain an advantageous effect of preventing a worker from being exposed to chemicals leaking out to the end cap member 3400 in advance.

Moreover, the end cap member 3400 does not directly contact the sampling lines L1, L2, L3, but is in close contact with the lower portion of the holder member 3420, and seals the outlet ends of the sampling lines L1, L2, L3. , It is possible to obtain an advantageous effect of more stably maintaining the arrangement state of the end cap member 3400 with respect to the sampling line (L1, L2, L3) and the state in which the outlet end is sealed.

In addition, according to a preferred embodiment of the present invention, a detection sensor (not shown) may be provided in the receiving groove 3402 for detecting a chemical leaked from the outlet ends of the sampling lines L1, L2, and L3.

As the detection sensor, a conventional sensor capable of detecting a chemical (eg, an optical sensor, an infrared sensor, and a capacitive sensor) may be used, and the present invention is not limited or limited by the type and sensing method of the detection sensor.

In addition, when a chemical leakage is detected by the detection sensor, the control unit (not shown) may generate an alarm signal for recognizing the chemical leakage situation to the worker.

Here, the alarm signal may include at least one of an audible alarm signal by a conventional sound means and a visual alarm signal by a normal warning light. An alarm signal can be used.

Hereinafter, a chemical sampling process by the chemical sampling device 310 according to an embodiment of the present invention will be described.

When an operator inputs a command to unlock the first door 3104 through an input unit (not shown), the lock state of the first door 3104 by the door locking device (not shown) is released.

When the lock state of the first door 3104 is released, the operator opens the first door 3104 to open the empty container 20 (a container with a lid attached to the holder module 3110) disposed in the waiting space 3102a. To accommodate.

Preferably, when the chemical sampling device 310 is initially operated, the initial position of the holder module 3110 may be set to the standby space 3102a. In some cases, it is also possible to set the initial position of the holder module 3110 as a work space.

When the first door 3104 is closed, the second door 3106 is opened and the container 20 accommodated in the holder module 3110 is It is transferred to the bottom.

When the second door 3106 is closed, the lid 22 coupled to the container 20 is separated by the lid removal unit 3300.

For reference, before the chemical is supplied to the container 20, the chemical remaining in the sampling lines L1, L2, and L3 is discharged in advance through the drain module 3120.

Before the chemical is sampled from the sampling lines (L1, L2, L3), the end cap member 3400 is disposed at a position (5th position) sealing the outlet ends of the sampling lines (L1, L2, L3), and the drain module The 3120 is disposed at a fourth position (standby position) spaced apart from the exit ends of the sampling lines L1, L2, and L3.

Next, when the holder member 3420 moves to the second position, the end cap member 3400 is disposed at a position (the fifth position) to seal the outlet ends of the sampling lines L1, L2, and L3, and then the container Before supplying chemicals to (20), it moves to the position (6th position) to open the outlet ends of the sampling lines (L1, L2, L3).

At this time, the time point at which the end cap member 3400 moves from the fifth position to the sixth position may be variously changed according to required conditions and design specifications.

For example, when the end cap member 3400 moves from the fifth position to the sixth position, the second door after the container 20 is transferred to the lower portion of the lid detachable unit 3300 provided in the work space 3102b. It may be the point at which 3106 is closed. According to another embodiment of the present invention, the time point at which the end cap member moves from the fifth position to the sixth position is a time point before (or after detachment) the lid coupled to the container by the lid detachment unit, It may be the point at which the first door is closed after the container first enters the waiting space.

Next, the drain module 3120 moves forward toward the sampling lines L1, L2, L3 by the second moving unit 3700, so that the entry port 3123 is aligned with the exit ends of the sampling lines L1, L2, L3. It is placed in the third position.

Next, as the holder member 3420 descends to the first position, the entry port 3123 is closed by the holder member 3420.

When the entrance port 3123 is closed by the holder member 3420, chemicals remaining in the sampling lines L1, L2, and L3 are discharged into the drain module 3120. In addition, while chemicals remaining in the sampling lines L1, L2, and L3 are discharged into the drain module 3120, a diluent may be supplied to the inside of the drain module 3120 together.

Next, when the chemical draining process is completed (for example, reaching a preset time), the holder member 3420 rises back to the second position, and the drain module 3120 is rearwarded by the second moving unit 3700. It is placed in the fourth position by moving to.

Next, the container 20 from which the lid 22 is separated is transferred to the lower part of the outlet end of the sampling lines L1, L2, L3 by the transfer unit, and the sampling lines L1, L2 inside the container 20 The chemical discharged from the outlet end of ,L3) is filled.

On the other hand, if a part of the chemical overflows while the chemical is supplied to the container 20, a sensor provided in the container 20 or around (for example, a holder module) can detect this, and the control unit senses the sensor. Depending on the value, the sampling process can be stopped and an alarm can be generated.

Thereafter, the container 20 filled with the chemical is transferred to the lower portion of the lid detachment unit 3300 by the transfer unit again, and the lid 22 is coupled by the lid detachment unit 3300.

Next, the second door 3106 is opened and the container 20 to which the lid 22 is attached is transferred to the waiting space 3102a by the transfer unit.

When the second door 3106 is closed, the operator opens the first door 3104 so that the container 20 disposed in the waiting space 3102a is pulled out of the case 3100 to perform the chemical contamination analysis process. do.

On the other hand, at the position where the end cap member 3400 opens the exit ends of the sampling lines L1, L2, and L3 (the sixth position), the position where the exit ends of the sampling lines L1, L2, and L3 are sealed (the fifth Position) is preferably carried out immediately after the container 20 filled with the chemical is transferred to the lower portion of the lid removal unit 3300 (or while being transferred). In this way, after the chemical is discharged from the outlet ends of the sampling lines L1, L2, L3, the outlet ends of the sampling lines L1, L2, L3 are sealed by the end cap member 3400, thereby sampling. It is possible to obtain an advantageous effect of minimizing the drop of chemicals remaining at the exit ends of the lines L1, L2, and L3.

On the other hand, at the position where the end cap member 3400 opens the exit ends of the sampling lines L1, L2, and L3 (the sixth position), the position where the exit ends of the sampling lines L1, L2, and L3 are sealed (the fifth Position) is preferably performed immediately after the lid 22 is fastened to the container 20 filled with chemicals. In this way, immediately after the lid 22 is fastened to the container 20 filled with chemicals, the outlet ends of the sampling lines L1, L2, L3 are sealed by the end cap member 3400, so that the first It is possible to obtain an advantageous effect of minimizing the introduction of foreign substances that may occur during the operation of the moving unit 3600 and the third moving unit 3500 into the inside of the container 20 filled with chemicals.

<Fourth Example>

39 is a conceptual diagram of a chemical sampling apparatus according to an embodiment of the present invention.

Referring to FIG. 39, the chemical sampling device according to the embodiment includes a case 4100 in which a container 21 to which a lid 22 is fastened is accommodated, a lid opening module for separating or fastening the container 21 and the lid 22 (4300, 4220), and the lid 22 may include a sampling line (L1, L2, L3) for filling the chemical into the separated container 21.

The container 21 may be a sampling bottle capable of extracting a part of the chemical, but is not limited thereto. Exemplarily, the container may be a drum in which a large amount of chemicals are stored. Hereinafter, it will be described as an exemplary sampling bottle.

The case 4100 may be divided into a waiting space 4100a and a working space 4100b by a shielding door 4102. The waiting space 4100a may be a space in which an operator accommodates the sampling bottle 21. In addition, the working space 4100b may be a space in which the lid 22 of the sampling bottle 21 is opened and chemicals are stored.

According to the embodiment, since the waiting space 4100a and the working space 4100b are partitioned by the shielding door 4102, it is possible to prevent chemical fumes generated during the sampling operation from being discharged to the outside.

However, the present invention is not limited thereto, and the working space 4100b may be divided into a plurality of pieces. For example, a shielding door may be additionally installed between the area in which the lid opening and closing device is disposed and the area in which the plurality of sampling lines L1, L2, and L3 are disposed. In this case, it is possible to more effectively suppress the discharge of chemical fumes to the outside.

When the operator opens the door 4103 and places the empty sampling bottle 21 in the waiting space 4100a and operates the device, the holder module 4220 transfers the sampling bottle 21 to the lower portion of the gripping part 4310. I can. The holder module 4220 may move in the transverse direction along the moving line 4104, but is not limited thereto.

During the initial operation, the holder module 4220 may be disposed in the waiting space 4100a. Accordingly, the operator can insert the sampling bottle 21 into the holder of the holder module 4220 and perform the sampling operation. However, the initial position of the holder module is not limited thereto.

The detachable module 4300, the cap detachable unit) includes a gripping part 4310 coupled to the lid 22, a rotating part 4320 for rotating the gripping part 4310, and an elevating part 4330 for elevating the gripping part 4310. It may include. According to the embodiment, the rotating part 4320 and the lifting part 4330 are disposed outside the case 4100 to prevent penetration of chemical fumes generated during the sampling operation.

The cover 4831 may be coupled to the upper portion of the case 4100, and may be formed in an expandable tubular shape to surround the through hole formed in the case 4100. For example, the cover 4831 may be a corrugated pipe. Therefore, it is possible to suppress the entry of the chemical fume through the through hole of the case 4100.

40 is a view showing a state in which the lid opening and closing device is coupled to the lid, and FIG. 41 is a view showing a state in which the lid is raised from the container by the lid opening and closing device.

Referring to FIG. 40, when the sampling bottle 21 is disposed under the detachable module 4300, the gripping portion 4310 may descend and be coupled to the lid 22. The configuration in which the gripper 4312 of the gripping portion 4310 is unfolded is not particularly limited. As an example, various gripper structures of robot arms can be applied without limitation.

At this time, the plate member 4318 disposed on the gripping part 4310 may be prevented from lowering the gripping part 4310 from the lid 22 by contacting the upper surface of the lid 22. In addition, since the plate member 4318 presses the lid 22, a problem in which the gripper 4312 is not properly closed due to the slip phenomenon of the gripper 4312 when the gripper 4310 rotates and descends can be improved.

The plate member 4318 may press the lid 22 by an elastic member such as a spring, but is not limited thereto. For example, the plate member 4318 may have an elastic force using magnetic force.

The rotating part 4320 may transmit a rotational force to the gripping part 4310 to separate the lid 22 from the sampling bottle 21. The rotating part 4320 may include a motor, but is not limited thereto. For example, the rotation unit 4320 may transmit rotational force by a cylinder. That is, the configuration of the rotating part 4320 is not particularly limited as long as it is a configuration capable of transmitting a rotational force to the gripping part 4310.

Referring to FIG. 41, a first thread 21a is formed in the injection port 21-1 of the sampling bottle 21 to be coupled to the second thread 22a of the lid 22. When the gripper 4312 of the gripping part 4310 grasps the lid 22 and rotates, the first thread 21a and the second thread 22a are separated, and in this process, the second thread 22a becomes the first thread. It is pushed up by (21a). Accordingly, the lid 22 gradually rises from the sampling bottle 21.

When the lid 22 rises from the sampling bottle 21 by rotation, if the weight of the detachable module 4300 is transferred to the lid 22 as it is, the lid 22 cannot rise any more and the first thread 21a The formed sampling bottle 21 may be pressed. Accordingly, the shape of the sampling bottle 21 may be modified.

The sampling bottle 21 is standardized in materials and shapes to accommodate chemicals, and the strength may not be relatively high. In particular, the strength of the injection port 21-1 of the sampling bottle 21 may be weaker. Therefore, when the weight of the detachable module 4300 is transferred to the sampling bottle 21 through the lid 22 as it is, the injection port 21-1 may be crushed.

When deformation occurs in the injection port 21-1, the chemical may not be normally filled into the sampling bottle 21 through the injection port 21-1, but may be exposed to the outside. Therefore, the configuration of separating the lid 22 without changing the shape of the sampling bottle 21 may be very important.

42 is a view showing a state in which the lid is separated from the container by the lid opening and closing device, and FIG. 43 is a view showing a state in which the lid opening and closing device is raised.

Referring to FIG.42, the buffer unit 4350 prevents the detachment module 4300 from pressing the lid 22 excessively, so that when the lid 22 rises, the gripping portion 4310 can also be pushed up. have. As a result, the adjustment interval d2 of the buffer unit 4350 may be reduced by the rising distance of the lid 22.

The buffer part 4350 may serve to reduce the weight of the gripping part 4310. For example, the buffer part 4350 is fixed to the rotating part 4320 and provides an elastic force upward, thereby reducing the weight of the gripping part 4310 pressing the lid 22. The configuration of the buffer unit 4350 is not particularly limited.

For example, the buffer unit 4350 may have an elastic structure such as a spring, a pneumatic structure such as a cylinder, and may include a motor. That is, the buffer unit 4350 is not particularly limited as long as it is a configuration capable of raising the gripping portion 4310 as well when the lid 22 is separated from the sampling bottle 21 and ascends.

The detection sensor 4371 may detect that the lid 22 is completely separated from the sampling bottle 21 according to the rise of the gripping portion 4310. The configuration in which the detection sensor 4371 detects that the lid 22 is completely separated from the sampling bottle 21 is not particularly limited.

For example, the detection sensor 4311 may include an optical transmitter and an optical receiver, and when the gripping part 4310 rises above a predetermined height, a signal transmitted from the optical transmitter may be blocked from being received by the optical receiver. Accordingly, if the optical signal is not received, it can be determined that the lid 22 is separated from the sampling bottle 21. However, the present invention is not limited thereto, and the detection sensor 4371 may have an electric or mechanical sensing structure.

Referring to FIG. 43, when it is determined that the lid 22 is completely separated from the sampling bottle 21, the holding portion 4310 may be raised. The lifting part 4330 may drive the cylinder to lift the gripping part 4310. At this time, the connection frame 4332 may be connected to the gripping part 4310, may be connected to the buffer part 4350, or may be connected to the rotating part 4320. That is, the connection frame 4332 may be connected to an appropriate position so that the detachable module 4300 can be moved up and down.

The detachable module 4300 can be lifted upward from the sampling bottle 21 by the lift unit 4330. In this case, the adjustment interval d2 of the buffer unit 4350 in the process of ascending and descending may be extended in the vertical direction again by gravity.

44 is a diagram showing a process of putting a chemical in a container.

When the detachable module 4300 rises after removing the lid 22, the control unit 4110 can move the holder module 4220 to sample the chemical selected by the operator among the plurality of sampling lines L1, L2, L3. have.

Chemicals can store various chemicals required for semiconductor processing and the like. Accordingly, when the sampling bottle 21 is disposed on the sampling lines L1, L2, and L3 through which chemicals requiring inspection are discharged, a supply device (not shown) is driven to fill the sampling bottle 21 with chemicals.

In this case, a drain module (not shown) for discharging chemicals remaining in the sampling lines L1, L2, and L3 may be further disposed. Chemicals filled in the sampling lines (L1, L2, L3) are likely to stagnate after a certain period of time, resulting in sediment or contamination through open discharge ports. Therefore, by discharging the chemicals remaining in the sampling lines L1, L2, and L3 before sampling, the reliability of chemical contamination analysis can be improved.

45 is a view showing a state in which the lid is coupled to the container, and FIG. 46 is a view showing a state in which the container has moved to the standby area.

Referring to FIG. 45, when the sampling bottle 21 is filled with chemicals, the holder module 4220 may place the sampling bottle 21 under the detachable module 4300 again.

The gripping portion 4310 may descend and rotate to couple the lid 22 to the sampling bottle 21. At this time, when the gripping part 4310 couples the lid 22 to the sampling bottle 21, the buffer part 4350 contracts again to prevent the gripping part 4310 from excessively pressing the sampling bottle 21. I can.

The lid 22 presses the sampling bottle 21 by the lowering of the gripping part 4310, but the weight of the gripping part 4310 is sufficiently reduced by the buffer part 4350, so that the gripping part 4310 becomes the sampling bottle. 21) can be pushed up.

Thereafter, by rotation, the lid 22 descends while being coupled to the sampling bottle 21, and the gripping portion 4310 may also descend to a height at which the lid 22 descends. As the gripping part descends, the buffer part 4350 may extend in the vertical direction again.

The detection sensor 4371 may detect that the lid 22 is completely coupled to the sampling bottle 21 by measuring the height of the lowering of the gripping part 4310. For example, the detection sensor 4311 includes an optical transmitter and an optical receiver, and when the gripping part 4310 falls below a predetermined height, a signal transmitted from the optical transmitter may be blocked from being received by the optical receiver. Accordingly, if no optical signal is received, it can be determined that the lid 22 is completely coupled in the sampling bottle 21.

According to an embodiment, a torque measuring unit (not shown) for measuring a torque value of the rotating unit 4320 may be included. The control unit 4110 may compare the torque value of the rotating unit 4320 with a preset torque value.

The control unit 4110 may determine that the lid 22 is coupled to the sampling bottle 21 when the torque value of the rotating unit 4320 is within a preset torque range. If the torque value does not reach the preset torque range, it may be determined that the lid 22 is not coupled to the sampling bottle 21 and is idle.

The controller 4110 may determine that the lid 22 is coupled to the sampling bottle 21 when a lid closing signal is detected by the detection sensor 4311 and the measured torque value is within a set range.

Accordingly, when the lid closing signal is detected but the torque value does not reach a preset range, it may be determined that the lid 22 is not coupled to the sampling bottle 21 and is idle.

In addition, when the torque value reaches the preset range but the lid closing signal is not detected, it may be determined that the lid 22 is erroneously fastened to the sampling bottle 21. In this case, since the control unit 4110 can output an error signal to the outside, it is possible to prevent an accident due to a bad fastening of the lid 22.

When the lid closing signal is sensed and the torque value reaches a preset range, the controller 4110 may separate the gripping portion 4310 from the lid 22 and lift the detachable module 4300.

Referring to FIG. 46, the controller 4110 may raise the shielding door 4102 and transfer the sampling bottle 21 to the waiting space 4100a. Accordingly, the operator can open the door 4103 and collect the sampling bottle 21.

47 is a cross-sectional view of the detachable module, Fig. 48 is an enlarged view of the buffer unit, and Fig. 49 is a view showing the height at which the detachable module moves up and down together with the lid by the buffer unit.

47 to 49, the detachable module 4300 includes a gripping part 4310 coupled to the lid, a rotating part 4320 for rotating the gripping part 4310, and an elevating part for lifting the gripping part 4310 ( 4330).

The gripping part 4310 may grip the lid, and may further include a plurality of grippers 4312, a frame 4313, and a plate member 4318 for this purpose.

The plurality of grippers 4312 may be rotatably coupled to the frame 4313 to support the side surface of the lid 22.

The frame 4313 is connected to the piston 4317 and can move in the vertical direction, that is, in the Z direction. The frame 4313 and the plurality of grippers 4312 may be connected by a connection link (not shown). The vertical linear motion of the frame 4313 may be converted into a rotational motion of the gripper 4312 by a connection link (not shown).

Therefore, when the frame 4313 is raised and lowered, the plurality of grippers 4312 are opened and separated from the lid 22, and when the frame 4313 is lowered, the plurality of grippers 4312 are close to each other to grip the lid 22. . However, the present invention is not limited thereto, and the plurality of grippers 4312 may be designed to be close to each other when the frame 4313 is lowered, and the plurality of grippers 4312 may be separated from each other when the frame 4313 is raised.

The plate member 4318 may be disposed under the frame 4313 and coupled to be vertically movable. The plate member 4318 may include an elastic member. For example, the elastic member may be a spring, but is not limited thereto, and a magnetic may be used.

The lower surface of the plate member 4318 may be disposed to face the upper surface of the lid held by the plurality of grippers 4312. Therefore, damage caused by collision with the sampling bottle 21 or the lid 22 can be suppressed when the gripping part 4310 is raised or lowered, and the sampling bottle 21 is in an upright state even if it is partially inclined Can be converted.

The frame elevating unit for elevating the frame 4313 may include a cylinder 4316 and a piston 4317. The piston 4317 is disposed in the inner space C1 of the cylinder 4316 and may move up and down according to the inflow of the fluid.

The piston 4317 may include a first rod 4317a extending upward and into which a fluid is injected, and a second rod 4317b extending downward and connected to the frame 4313.

The cylinder holder 4340 may be provided with fluid ports 441 and 4342 for injecting a fluid into the inner space C1 of the cylinder 4316. In addition, fluid passages 4317a-1 and 4317a-2 connected to the fluid ports 441 and 4342 of the cylinder holder 4340 may be formed in the first rod 4317a.

For example, when fluid is injected into the first fluid passage 4317a-1, the fluid is discharged into the lower space R1 of the piston 4317, so that the piston 4317 rises. On the contrary, when fluid is injected into the second fluid passage 4317a-2, since the fluid is injected into the upper space R2 of the piston 4317, the piston 4317 descends. With this configuration, the gripper 4312 can be driven by raising and lowering the piston 4317.

However, the configuration for raising and lowering the piston 4317 may be variously modified, but is not necessarily limited thereto. For example, it may be configured as a motor. In addition, the structure of gripping the lid 22 using the gripper 4312 may be variously modified.

The cylinder 4316 may be rotated by being coupled to a rotation shaft of the rotation unit 4320. The cylinder holder 4400 may support the rotating cylinder 4316. The first fastening member 443 and the second fastening member 433 may fix the cylinder holder 4400 to the connection frame 4332. The end of the cylinder 4316 may protrude from the cylinder holder 4400 and be connected to the buffer unit 4350.

Referring to FIG. 48, the buffer unit 4350 includes a buffer housing 4351 having a space C3 formed on one side thereof, a buffer cover 4435 covering one side of the buffer housing 4351, and the interior of the space C3. It may include a moving member 4352 disposed in the and an elastic member 4355 disposed between the moving member 4352 and the buffer cover 4434.

The buffer housing 4351 may include a space C3 into which the moving member 4352 is inserted. The moving member 4352 may slide up and down in the interior of the space C3 by the buffer cover 4434. One end of the elastic member 4355 may be fixed to the buffer cover 4344.

Since the end of the cylinder 4316 is connected to the moving member 4352, the moving member 4352 can be lowered by the weight of the gripping portion 4310. Accordingly, since the elastic member 4355 is pressed by the moving member 4352, it may have an elastic force in the upwardly lifting direction. Accordingly, the weight applied by the gripping portion 4310 to the sampling bottle 21 by the elastic member 4355 may be reduced.

For example, when the weight of the gripping portion 4310 is 1.5 kg, the weight applied to the sampling bottle 21 by the elastic member 4355 may be reduced to 0.8 kg. As the elastic force of the elastic member 4355 increases, the weight applied to the sampling bottle 21 may decrease.

Accordingly, when the lid 22 gradually rises while being separated from the sampling bottle 21, the gripping portion 4310 may rise due to the lifting force of the lid 22. In addition, while the lid 22 is fastened to the sampling bottle 21, the gripping portion 4310 may descend. However, the structure of the buffer unit 4350 is not necessarily limited thereto, and various buffer structures capable of controlling the weight of the gripping unit 4310 may be applied.

The buffer housing 4351 may include a protrusion 4355 protruding from the other side and connected to the rotating part 4320. The protrusion 4355 may be connected to the rotating shaft of the rotating part 4320 by a connection module 4321.

The cylinder 4316 of the gripping part 4310 may be fixed to the moving member 4352. Therefore, when the rotating part 4320 rotates, the buffer part 4350 and the gripping part 4310 may rotate together.

Referring to FIG. 49, it can be seen that as the gripping part 4310 rises, the gap between the buffer part 4350 becomes narrower. Accordingly, the rising distance d1 of the gripping portion 4310 may correspond to the adjustment interval d2 of the buffer portion 4350.

50 is a view showing a state in which the modified detachable module moves up and down together with the lid.

Referring to FIG. 50, the buffer part 4350 may be disposed between the gripping part 4310 and the lifting part 4330. Specifically, the buffer part 4350 is a sliding member 4357 protruding upward from the elevating part 4330 and penetrating the connection frame 4332, a stopper 4356 disposed above the sliding member 4357, and a connection frame It may include an elastic member (4353) arranged to lift the (4332) upward. Exemplarily, the elastic member 4355 may have one end fixed to the stopper 4356 and the other end fixed to the connection frame 4332.

According to this configuration, as described above, since the elastic member 4355 can reduce the weight of the gripping part 4310, the gripping part 4310 can be pushed to the lid 22 and rise. However, since the weight applied to the lid 22 is the total weight of the detachable module 4300 including the gripping part 4310 and the rotating part 4320, the weight applied to the sampling bottle 21 may be relatively large. In contrast, in the structure of FIG. 49, since the buffer part 4350 is between the gripping part 4310 and the rotating part 4320, the weight applied to the lid 22 may be reduced by the weight of the gripping part 4310. Therefore, there is an advantage of minimizing deformation of the sampling bottle by reducing the weight.

51 is a conceptual diagram of a holder module, FIG. 52 is a diagram showing a second detection sensor disposed in the holder module, and FIG. 53 is a conceptual diagram of a second detection sensor.

51 and 52, the holder module 4220 includes a first holder 4221a and a second holder 4221b spaced apart from each other for fixing the sampling bottle 21, a first holder 4221a, and a second holder. It may include a driving module 4223 for moving the 4221b, and a moving rail 4222. The first holder 4221a and the second holder 4221b may include a second detection sensor 4224 disposed on opposite surfaces. The second detection sensor 4224 may be a liquid detection sensor that senses a chemical.

Referring to FIG. 53, the second detection sensor 4224 includes a cover layer 4224a that protects the first and second metals 4224b and 4224c spaced apart from each other, and the first and second metals 4224b and 4224c, and It may include a power supply (4224d) for applying power.

Since the cover layer 4224a is made of a flexible material, the second detection sensor 4224 may be fixed to the inner surfaces of the first holder 4221a and the second holder 4221b.

A voltage may be applied to the first and second metals 4224b and 4224c. Since the first and second metals 4224b and 4224c are spaced apart from each other, current does not flow normally, but when the conductive chemical CH is buried, current flows. Accordingly, when the second detection sensor 4224 detects that current flows, the controller 4110 may determine that the chemical is exposed and output a warning signal. However, the method of detecting the exposure of the chemical is not limited thereto. For example, by measuring the resistance, the exposure of the chemical may be measured, or a voltage change may be used.

In addition, the second detection sensor 4224 may be disposed inside the case 4100 to sense a chemical away from the sampling lines L1, L2, and L3. In addition, the second detection sensor 4224 may sense a chemical overflowing from the sampling bottle 21 due to an error of a sensor measuring the amount of sampling or an error such as a time check. In this case, the second detection sensor 4224 may be disposed on the lower and side surfaces of the sampling lines L1, L2, and L3, but is not limited thereto.

54 is a flowchart illustrating a sampling method according to an embodiment of the present invention.

Referring to Figure 54, the sampling method according to the embodiment, the step of fixing the container (S10), the step of separating the lid coupled to the container (S20), the step of filling the container with a chemical (S30), the lid to the container It may include the step of combining (S40), and the step of transferring the container to the waiting space (S50). The lid opening and closing method may include fixing the container (S10), separating the lid coupled to the container (S20), and coupling the lid to the container (S40).

Referring to FIG. 39, in the step of fixing the container (S10), when the operator opens the door 4103 and places the sampling bottle 21 in the waiting space 4100a, the holder module 4220 is the sampling bottle 21 Can be gripped.

Referring to Figure 40, the step of separating the lid coupled to the container (S20), when the holder module 4220 transfers the sampling bottle 21 to the lower portion of the detachment module 4300, the wave of the detachment module 4300 The branch 4310 may descend and be coupled to the lid 22 of the sampling bottle 21. Thereafter, while the holding portion 4310 rotates, the lid 22 may be separated from the sampling bottle 21.

At this time, when the lid 22 rises in the process that the thread of the lid 22 is separated from the thread of the sampling bottle 21, the gripping part 4310 also rises together with the lid 22 by the buffer part 4350. I can. According to this configuration, while the lid 22 rises, the grip portion 4310 does not rise, so that a problem in which the shape of the sampling bottle 21 is deformed can be solved.

Even when the lifting part 4330 raises the gripping part 4310, the rotating part 4320 may continue to rotate the gripping part 4310. According to this configuration, it is possible to prevent the thread of the sampling bottle 21 and the end of the thread of the lid 22 from being caught by the continuous rotation of the lid 22. Accordingly, it is possible to prevent the sampling bottle 21 from being caught on the lid 22 or damaging the screw thread.

Referring to FIG. 44, in the step of filling the container with chemicals (S30), the sampling bottle 21 may be transferred to a predetermined position so as to fill the chemicals required for inspection. Before charging the chemicals in the sampling lines L1, L2, and L3, the chemicals remaining in the sampling lines L1, L2, and L3 may be discharged in advance. Chemicals filled in the sampling lines (L1, L2, L3) are likely to stagnate after a certain period of time, resulting in sediment or contamination through open discharge ports. Therefore, it is possible to increase the reliability of chemical contamination analysis through the drain operation.

At this time, since the second detection sensor 4224 is disposed in the holder module 4220 as shown in FIG. 42, the controller 4110 determines that the chemical is exposed to the outside when a detection signal is output from the second detection sensor 4224. Warning signal can be output. Alternatively, when a detection signal is sensed by the second detection sensor 4224 disposed under the case 4100, a warning signal may be output.

Referring to FIG. 45, in the step of coupling the lid 22 to the container (S40), when a chemical is contained in the sampling bottle 21 and disposed under the detachable module 4300, the gripping part 4310 is lowered. Thus, after placing the lid 22 on the top of the sampling bottle 21, the lid 22 can be coupled to the sampling bottle 21 by rotating.

At this time, as described above, since the weight of the gripping part 4310 pressing the sampling bottle 21 by the buffer part 4350 can be reduced, the sampling bottle 21 may sufficiently support the gripping part 4310.

Thereafter, as the lid 22 and the sampling bottle 21 are coupled by rotation, the lid 22 descends, and the gripping portion 4310 may also descend like the lid 22.

When lowering to the position where the lid 22 and the coupling is completed, the detection sensor 4311 may transmit a closing detection signal to the control unit 4110. In addition, the torque measurement unit may measure the torque value of the motor of the rotation unit 4320 and transmit it to the control unit 4110.

The control unit 4110 may determine that the lid 22 is coupled to the sampling bottle 21 when the torque value of the rotating unit 4320 is within a preset torque range. If the torque value does not reach the preset torque range, it may be determined that the lid 22 is not coupled to the sampling bottle 21 and is idle.

The control unit 4110 may determine that the lid 22 is coupled to the sampling bottle 21 when a signal for closing the lid 22 is detected by the detection sensor 4311 and the torque value is within the set range. .

Accordingly, when the lid closing signal is detected but the torque value does not reach a preset range, it may be determined that the lid 22 is not coupled to the sampling bottle 21 and runs idle.

In addition, when the torque value reaches a preset range but the lid closing signal is not detected, it may be determined that the lid 22 is erroneously fastened to the sampling bottle 21. In this case, since the control unit 4110 can output an error signal to the outside, it is possible to prevent dangers and accidents due to non-fastening of the lid 22.

When the lid closing signal is detected and the torque value reaches a preset range, the control unit 4110 may separate the gripping part 4310 to the lid 22 and lift the detachable module 4300.

In the step of transferring to the standby space, the sampling bottle 21 to which the lid 22 is coupled may be transferred to the standby space and an alarm signal may be output to the outside. Thus, the operator can open the door 4103 and retrieve the sampling bottle 21.

It will be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiment can be modified and implemented. And differences related to these modifications and applications should be construed as being included in the scope of the present invention defined in the appended claims.
