The embodiment relates to a lid opening and closing device and a chemical sampling device including the same.

Companies that handle chemicals harmful to the human body, for example, companies that manufacture semiconductors, LCDs, OLEDs, pharmaceuticals, etc., or companies that manufacture chemicals such as paint companies, use various types of chemicals in one or multiple unit processes. have.

In general, the chemical is supplied to the main storage tank through a tank lorry, etc., and a part of the chemical stored in the main storage tank is divided and stored in a plurality of sub storage tanks, so that it is sequentially supplied to one unit process or individually to a plurality of unit processes can be supplied.

As another example, if there is a small amount of chemicals or if a tank lorry cannot be used due to the nature of the chemical itself, it may be directly supplied to the sub storage tank through a drum, a bottle, or the like.

If chemicals are contaminated in tank lorries, drums, bottles, storage tanks, pipes, etc., defects may occur in the unit process that receives them.

Therefore, the level of chemical contamination needs to be managed at an appropriate level for each major location such as tank lorry, drum, bottle, storage tank, and piping, and accordingly, a sampling device capable of sampling chemicals at major locations has been developed.

A conventional sampling apparatus includes a sampling booth, a plurality of sampling lines connected to a plurality of main positions to supply chemicals to sampling bottles stored in the sampling booth, and valves respectively installed in the plurality of sampling lines.

The operator was able to perform the sampling operation as follows using a conventional sampling device.

For example, the operator directly opens the lid of the sampling bottle and puts the sampling bottle into the sampling booth, operates the valve on the sampling line connected to the main location to be sampled, fills the sampling bottle with chemicals, and places the chemical-filled sampling bottle into the sampling booth. After collection, the sampling bottle was directly closed and transported to the chemical contamination level analysis site.

As described above, most of the sampling operation was generally performed manually by an operator.

Therefore, there is a problem that there is a high possibility that chemical contamination occurs due to negligence of the operator during the sampling operation, and there is also a problem that the operator is highly likely to be exposed to chemicals.

These problems are particularly likely to occur when the operator opens and closes the lid of the sampling bottle.

On the other hand, when chemical contamination occurs during the sampling operation, the reliability of the chemical contamination level analysis result may be reduced. In addition, for worker protection, the inconvenience of having to prepare, wear, and take off safety gear of the highest level of protection may occur.

The embodiment provides a lid opening and closing device capable of automatically opening and closing a lid in a container, and a chemical sampling device including the same.

The second frame 313 may be disposed on the horizontal plate area of the first frame 311 , and may move in the vertical direction, that is, in the Z-axis direction by the frame lifting unit 315 .

The plurality of connection links 314 may be the same number as the plurality of grippers 312 , for example, three, and each connection link 314 is rotatable to each gripper 312 and the second frame 313 . can be tightly coupled. The vertical linear motion of the second frame 313 may be converted into a rotational motion of the gripper 312 through the connection link 314 .

For example, as shown in FIG. 7 , the plurality of grippers 312 may be separated from the lid C by rotating in the forward direction so that respective grip surfaces of the second frame 313 are moved away from each other when the second frame 313 is raised, as shown in FIG. 7 . In addition, as shown in FIG. 8 , the plurality of grippers 312 may grip the lid C by rotating in the reverse direction so that the respective grip surfaces are closer to each other when the second frame 313 is lowered.

The frame lifting unit 315 may be coupled to the first frame 311 to transport the second frame 313 in the Z-axis direction.

The frame lifting unit 315 may include a pneumatic cylinder, but is not limited thereto, and may include other lifting means such as a hydraulic cylinder.

The plate member 318 may be disposed at a lower portion of the first frame 311 and may be coupled to the first frame 311 to be vertically movable.

The plurality of elastic members 319 may be interposed between the first frame 311 and the plate member 318 to provide an elastic force to the plate member 318 to maintain the plate member 318 in a horizontal state.

For example, the plurality of elastic members 319 may be spaced apart from each other in a horizontal direction.

idle rollers

215 , 216 , 217 are positioned to contact the side surface of the sampling bottle B, thereby completing the loading of the sampling bottle B.

The sampling bottle (B) may be input and collected in a state in which the lid (C) is coupled. Therefore, it may be sufficient if the operator is wearing only the safety gear of the general protection level, not the highest level of protection.

When a lock command for the first door 103 is input through the input unit 700 , the controller 710 may control the door locking device 720 to switch the first door 103 to a locked state.

However, in order to always lock the first door 103 by the operator's input, the control unit 710 determines whether the first door 103 is closed according to a sensing value of a door sensor (not shown) that detects whether the first door 103 is closed. (103) can also be switched to the locked state.

In the above, the embodiment has been mainly described, but this is merely an example and does not limit the present invention, and those of ordinary skill in the art to which the present invention pertains are not exemplified above in the range that does not depart from the essential characteristics of the present embodiment. It can be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiment can be implemented by modification.

For example, although it has been described that the first bottle-mounted transfer unit and the second bottle-mounted transfer unit are independently configured in the embodiment of the chemical sampling device, two bottle-mounted transfer units may be integrated into one.

In addition, after transferring the first bottle-mounting transfer unit to the position of the cap detachment module, remove the cap from the sampling bottle on the bottle-mounted transfer unit, or combine the cap with the sampling bottle, and move the sampling line after the cap is removed from the sampling bottle to fill the sampling bottle with the chemical into the container. In this case, the second bottle mounting transfer unit may be omitted.

Alternatively, the cap detachment module is transported to the position of the first bottle mounting transport unit to separate the cap from the sampling bottle on the first bottle mounting transport unit, or the cap is coupled to the sampling bottle, and the sampling line is disconnected after the cap is removed from the sampling bottle. The chemical may be filled into the sampling bottle by transporting it to the position of the first bottle-mounted transport unit. In this case, the first bottle transfer unit and the second bottle transfer unit of the first bottle transfer unit may be omitted.

Accordingly, it should be construed as being included in the scope of the present invention as defined in the appended claims for differences related to such modifications and applications.
