Description

Cap opening and closing means of automatic chemical supply and filling system {Filling system and Automatic chemical supply}

The present invention relates to an automatic chemical supply and filling system, and more specifically, to enable smooth and safe filling of chemicals inside a chemical filling container through automation, thereby fundamentally preventing chemical contamination during the operation. This relates to a means of opening and closing the cap of an automatic chemical supply and filling system that can minimize the risk of workers being exposed to dangerous chemicals.

In general, companies that handle chemicals that are harmful to the human body, such as companies that manufacture semiconductors, LCDs, OLEDs, pharmaceuticals, etc., or companies that manufacture chemicals such as paint companies, use one or more types of chemicals. It is used in unit processes.

Companies that use chemicals are supplied with various types of chemicals stored in various containers such as drums and bottles, and companies that produce chemicals are supplied with empty containers.

Therefore, in order to use the chemicals supplied in the container at a semiconductor company, etc., it is necessary to open the lid of the container, insert the immersion tube module into the container, inhale the chemicals, and store them in a storage tank inside the company or supply them to the point of use.

Or, conversely, a immersion tube module can be inserted into an empty container to fill it with chemicals.

In this way, the worker directly opens the lid of the chemical container, inserts the immersion tube into the container, and inhales the chemical, thereby supplying it to the storage tank or the place of use. Or, conversely, filling the empty container. When the inhalation or filling of the chemical is completed, the chemical is smeared again. Remove the immersion tube from the chemical container and close the lid of the container.

As such, most of the work is generally performed manually by workers.

Therefore, when the worker directly opens and closes the lid, the fume from the chemical container is exposed to the outside, and when the immersion tube is inserted into or removed from the container, the medicine on the immersion tube leaks. In addition, due to the worker's carelessness, there is a high possibility that the worker will be exposed to dangerous chemicals, which may cause the inconvenience of having to prepare, put on and take off safety gear of the highest protection level to protect the worker, and wear such clothing. There was a problem that another risk could occur due to incorrect operation due to this thick and uncomfortable safety protective gear that did not allow for smooth movement.

In order to solve the above problem, the existing drug supply system minimizes operator manpower by automatically switching to supplying drugs stored in another drug storage tank when the drug in the drug storage tank being used is exhausted. On the other hand, in order to replace the chemical storage tank when the chemical in the chemical storage tank is exhausted, the worker must wear safety gear of the highest level of protection, including a gas mask, chemical-resistant full body suit, chemical-resistant gloves, and chemical-resistant boots, and then the chemical is exhausted. The empty chemical storage tank had to be replaced with a chemical storage tank full of chemicals, but there was a problem with the risk of malfunction during replacement work due to safety protection equipment that did not allow workers to move smoothly.

In particular, the existing supply system has a problem in that the device for opening and closing the cap of the container is very complicated and malfunctions in opening and closing occur.

Figure 3 is a plan view for explaining the configuration of a chemical filling system according to an embodiment of the present invention, and Figure 4 is a side view for explaining the configuration of a chemical filling system according to an embodiment of the present invention.

As shown in Figures 1 to 4, the system 100 for automatically supplying and filling chemicals according to an embodiment of the present invention is installed at least one at the lower end of the support frame 110 and includes a chemical filling container ( A loading means 120 that stably supports the chemical filling container 10 and is capable of moving to the position where 10) is introduced and the position where the nozzle is provided, as well as enabling a raising and lowering operation, and the loading means 120 A transport means 130 that is installed in conjunction with and moves the loading means 120 back and forth, and a pump that is installed in conjunction with the chemical storage unit, moves along the upper rail of the support frame 110 to load a chemical filling container. It includes a filling means (140) for filling chemicals into the interior of (10), and an opening/closing means (200) that moves along the rail to open/close the cap (11) provided in the chemical filling container (10). .

The support frame 110 is equipped with an alien sensor (S1), a container detection sensor (S2), a load cell (S3), and a laser sensor (S4) to detect information about the drug filling container 10 being input, and the sensor Since their role is general technology, detailed explanation will be omitted.

The support frame 110 is provided with a filling chamber 111, and the filling chamber may consist of one or more.

In addition, each filling chamber 111 is comprised of a loading means 120 and a transfer means 130 that move and support the chemical filling container 10, and the loading means 120 is installed in conjunction with the transfer means 130. It is made to move back and forth through the transport means 130.

The loading means 120 can move forward along the rail (R), and moves forward through the transfer means 130 when the chemical filling container 10 is inserted, and the chemical filling container 10 is seated. , it moves backwards through the transfer means 130 to the location of the injection nozzle 143.

In addition, a raising and lowering cylinder 121 interlocked with the loading plate 122 is provided at the lower end of the loading plate 122, and is raised and lowered by driving the raising and lowering cylinder.

Meanwhile, the transfer means 130 is provided with a push prevention bar 1320 to prevent the drug from being pushed backward when the medicine filling container is inserted, and is provided with a cylinder 131 that moves the loading means 120 forward and backward. The rod of the cylinder is connected to the main part of the loading means.

The filling means 140 includes a hard first pipe 141 connected to the pump (P), a flexible second pipe 142 connected to the first pipe 141, and the second pipe ( 142), and is composed of an injection nozzle 143 that flows into the inside of the chemical filling container 10 through the injection port of the chemical filling container 10 through the raising and lowering means 146 and injects chemicals.

The pump (P) is provided at one end of the support frame 110 and is linked to a storage part where chemicals are stored.

In addition, a hard fixed first pipe 141 is provided perpendicular to the pump P, and a second pipe 142 is provided at the raised end of the first pipe 141, and injection is introduced into the second pipe. A nozzle 143 is provided.

That is, the chemicals in the storage unit are injected through the pump (P) into the chemical filling container loaded through the first pipe, the second pipe, and the injection nozzle 143.

The injection nozzle 143 is linked with the driving means 150, and the driving means 150 is provided at the top of the support frame 110.

The driving means 150 includes an injection nozzle guide frame 151 mounted on rails R1 installed at both upper ends of the support frame 110, and a drive motor 153 installed on the guide frame 151. It consists of a drive unit 152 that moves the injection nozzle 143 by moving left and right.

That is, the injection nozzle 143 is installed in conjunction with the drive unit 152, moves left and right through the drive motor 153 provided at one end, and the drive unit 152 is linked with the injection nozzle guide frame 151. It is installed and moves back and forth along the rail (R1).

In this way, the injection nozzle 143 can be moved to coincide with the injection port and center of the chemical filling container 10 by moving forward and backward and left and right.

Meanwhile, the first pipe and the second pipe are assembled and supported by a bushing (Ba) and a bearing (B), so that the connection portion between the second pipe and the first pipe may be distorted or the second pipe may be distorted depending on the movement path of the injection nozzle. Deformation of the bending phenomenon is prevented.

That is, when the injection nozzle 143 is moved through the driving means 150, the second pipe rotates with respect to the first pipe. If the first pipe and the second pipe are integrated, the problem of bouncing occurs. However, in the present invention, the first pipe and the second pipe are individually constructed, but are connected through a bushing and a bearing to rotate according to the movement path, thereby preventing deformation such as distortion.

And the outer periphery of the second pipe 142 has a certain thickness that can support the second pipe 142 by stretching and contracting along the movement path while preventing sagging of the second pipe 142, and has a plate shape. A guide plate 144 is provided.

For example, when three chemical filling containers 10 are inserted, a difference in distance occurs depending on the path when the injection nozzle moves.

That is, if the distance between the center of the first pipe 141 and the inlet of the chemical filling container 10 disposed in the center is 100 mm, the distance between the first pipe 141 and the inlet of the chemical filling container disposed at both ends is 100 mm or more. At this time, since the guide plate 144 is tilted toward the front and the distance is expanded, the distance between the first pipe and the injection port is secured and the injection nozzle can be moved to the injection port.

In this way, the guide plate 144 can be deformed into a plate-shaped steel plate with a certain thickness and thus can play a role in stably supporting the injection nozzle.

Meanwhile, the opening and closing means 200 scans the upper end of the medicine filling container 10 to detect the position (central axis) of the cap 11, and the opening and closing device 230 is positioned at the central axis of the cap 11. A vision sensor 210 that allows you to reach,

An opening and closing device 230 that moves to the upper central axis of the cap 11 to open or close the cap 11 when the center position on the cap is input through the vision sensor 210;

It consists of a detection sensor 220 that detects whether the cap 11 provided in the medicine filling container 10 is open or closed.

The vision sensor 210 functions to sense the position of the cap by scanning the cap 11 at the injection port of the medicine filling container 10 and transmits the sensed center position on the cap to a control unit (not shown).

The information entered as above is used as information to transfer the opening and closing device 230 to the center of the cap 11.

In this way, the opening and closing device 230 is transferred to the upper center of the cap 11, and the cap 11 is separated through the opening and closing device.

The opening and closing device 230 consists of a motor 231 and a cylinder 232, and an expansion member 234 is formed on the axis of the motor.

Additionally, a traction member 235 is provided at the lower end of the expansion member 234 through the housing 233, and a traction pin 236 is formed on the lower circumference of the traction member 235.

At this time, the housing 233 is fixedly installed with an installation plate 232a provided at the end of the cylinder 232.

That is, when the cylinder 232 is lowered while being transported to the upper center of the cap and retracted into the inner periphery of the cap under the traction member 235, the expansion member 234 is lowered to expand the expansion member 234 to the outside. At this time, the traction pin 236 provided at the bottom of the traction member 235 extends and comes into close contact with the inner periphery of the cap, so that the inner periphery of the cap is pulled.

In this state, the cap is rotated by the rotational drive of the motor 231 to open the cap closing the injection port.

In addition, when closing after opening, the cap can be inserted into the inlet by operating in the reverse direction of the above operation.

That is, in the method of opening and closing the cap through the opening and closing means 200, the jig sensor 210 is first moved to the adjacent part of the cap, scans the surrounding area of the cap, and transmits the center information of the cap to the control unit, and secondarily, The control unit moves the opening and closing device 230 to the upper center of the cap through the collected information.

Then, the third-way opening and closing device operates to pull and open the cap, and the cap detection sensor 220 detects whether the cap is accurately opened. When opening is completed, the control unit controls the driving means 150 to move the injection nozzle into the chemical filling container. It is transferred to the upper center of the injection port of (10), the raising and lowering means (146) is operated to introduce the injection nozzle into the chemical filling container (10), and then the filling of the chemical is started.

Meanwhile, a cleaning means 160 is provided at one end of the support frame 110 for cleaning the spray nozzle when chemical injection is completed.

Since cleaning is performed through the cleaning means 160, the risk of deterioration can be prevented even if different types of chemicals are used.

As seen above, the present invention can maximize work efficiency by more stably opening or closing the cap that seals the drug filling container, and is linked with the injection nozzle according to the movement path of the injection nozzle for filling the drug. Smooth filling can be achieved by preventing deformation of the installed first and second pipes, thereby fundamentally preventing chemical contamination during the work and minimizing the risk of workers being exposed to dangerous chemicals.

Above, specific embodiments of the present invention have been described.
