The present invention relates to the inspection of leakage of a high-pressure gas filling container, such as a container such as L.P gas, and more particularly relates to a rotary type automatic gas leakage test suitable for filling stations with a large amount of shipment.

The present invention will be described in more detail by arranging six closed inspection chambers capable of inspecting the filling gas container in a rotary type on a turn table to organize related configurations so that continuous inspection work can proceed. And the instrument control system is to be electronically automated to provide a device with a high degree of inspection method and ease of operation and handling.

As is well known, because L.P gas is highly explosive, various regulatory measures are specified in related laws for safety management. For example, after filling a container with L.P gas, an electronic gas tester is required to maintain 30 seconds in a closed laboratory. Therefore, the time required to inspect a container should include a 30-second rule and the time to handle the container, there is a problem that the supply and demand is not enough in time.

Prior to the advent of electronic gas detectors, a method of immersing a filling container in a fire has been practiced, but this method has recently been avoided because of the many unreasonable factors. That is, since the container filled with the gas is immersed in the water tank to visually determine whether bubbles are generated, the handling and operation of the gas container is difficult, and the unit measurement of the leaked gas amount (PPM) is impossible. If you continue the inspection several times, soil, dust, rust, etc., in the gas container will be mixed with the water of the tank, and it will not be able to determine whether bubbles are generated. The delay and the test time will be further delayed.

In particular, when the gas container is wet with water, it is naturally corroded prematurely, and in winter, the valve wetted with water freezes, thus making it difficult to open and close the operation, and a separate container drying device may cause gas leakage due to freezing accident. There are many problems that are difficult to overcome, such as the need to install. Therefore, in recent years, a method of inspecting gas leakage without immersion in a water tank, that is, a device that checks for airtightness by operating an alarm when a gas leak is put into a closed laboratory and waiting for a predetermined time has been used. There were many inherent points.

Firstly, in productivity (inspection rate), it takes about 45-50 seconds per unit, including the specified inspection time (30 seconds) and the time of injecting and withdrawing gas containers into the laboratory. Therefore, even if the operator is incessantly inspected, only 70-80 minutes of gas can be handled per hour, which is a very low quantity, which is insufficient for supply.

Secondly, in terms of efficiency, since the gas container is handled by hand, the worker easily feels tired, and the inspection is stopped during the intermittent break, thus the efficiency is low.

Third: In the installation and handling of equipment, the installation of multiple devices not only takes up a lot of space, but also leads to an increase in the number of workers.

The present invention has been studied for the first time in order to solve the above conventional problems, it is a rotary type having a plurality of examination rooms. The purpose of the invention of such a rotary gas container leak tester is to significantly increase production. In other words, the six chambers are rotated while being rotated in stages, and the gas container injection → rotation (leak inspection) → withdrawal process is repeated repeatedly. By performing the operation to take out the conventional speed of processing 70-80 minutes per hour is to be processed in a significant amount of about 300 copies.

Another object of the present invention is to ensure the accuracy of the leak test because the gas container is withdrawn at the end after being inspected for a sufficient time during the first electric charge after the input at the start. That is, in the prior art, the inspection time could be reduced by drawing out a predetermined time (30 seconds) ahead of the worker to increase the amount of work, but in the present invention, since the drawing is completed after one rotation is completed, the gas leakage inspection can be completed for a sufficient time. Is there.

Another object of the present invention is to facilitate the operator's convenience by making all the operations automatic. That is, the operator moves the gas container, opens and closes the inspection room door, inspects and leaks all the processes automatically, so that the operator observes and handles only the signals and movements of the device.

A feature of the present invention that can achieve the above objects is achieved by allowing all operations to be performed while the turntable is rotated one cycle (one cycle) and also allowing the same operation to continue to operate.

In addition, the rotary float, water, dry, and fills 27 and 27 'are connected to the pressure switch 25, and the test line door is opened and the close valves SVoc1-SVoc6 are connected to the supply line 2, respectively.

In the drawings, reference numerals 27 and 27 'denote filters, 28 denote gas container conveying conveyors, 29 denote closed rubber plates, 30 denote hinge shafts, and 31 denote digital meters. In the operation process of the present invention configured as described above, the filling gas container (G) is conveyed to the conveyor (28) to be continuous in the order of robot → laboratory injection, rotation, inspection → withdrawal. It is conveyed to the input part IN along the roller of the conveyor. When the gas container G reaching the input part enters into the roller plate 20 of the robot R that is in the air as shown in FIG. 9 (a) and approaches the inner wall, the light detector 21 of the robot R ( 21 ') and signal it to the central controller (CB).

The central eliminator (CB) commands the pneumatic system so that the clamp cylinder (C ₆ ) is operated so that the robot arm (18), which has been opened outward, grasps the gas container (G) while inward. . When the robot arm 18 claps the gas container, the mauve cylinder (C ₃ ) is operated to rotate the robot (R) by 90 ° C. toward the test chamber piece as shown in FIG. 9 (b), and the carrier cylinder (C). ₁ ) moves continuously to the laboratory 9 as shown in (c).

The sealed door 10 of the first laboratory 9 is placed in the already open state by operating the _first cylinder DC ₁ of the pneumatic line Line 2 according to the command of the central controller CB. ) Stops by reaching the gas chamber (G) in front of the open laboratory 9 and at the same time the robot arm is opened, the pusher (19) the gas container (G) by the pusher cylinder (C ₂ ) It will be pushed inside. (See Fig. 9 (c).) In this process, since the dustproof reinforcement table 16 (16 ') is partitioned on the inner surface of the examination room (9), the gas detector (S) (S') is protected and the bottom roller (11) Since it is formed to be easy to insert the container is also safe. The pusher cylinder C ₂ is then returned to its original position and the robot retracts from the examination room 9 by the operation of the carrier cylinder C ₁ to reach the end (see FIG. 9 (d)). C ₃ ) rotates by 90 ° C. to the initial state (see Fig. 9 (a)).

On the other hand, as shown in FIG. 10, the inspection chamber 9 into which the gas container G is inserted is contacted with the limit switch while the closing door 10 is closed by the cylinder DC ₁ , and accordingly, the gas inspection device GC is turned on to stir. While the blower 13 stirs the air inside the test chamber evenly, the swivel table 3 including the 6 test chambers 9 rotates and the inside of the test chamber is inspected for leakage of gas in the test chamber during one rotation. That is, the agitation blower 13 detects the concentration of the air while rapidly stirring the internal air. If the gas leaks, the gas detector (S) (S ') signals the alarm lamp and the buzzer sounds at the same time. Since the number indicating the leakage concentration is displayed on the digital meter 31, the operator recognizes the examination room, and then separates the leakage container in the withdrawal process described later.

The rotation of the swivel 3 is carried out by the dog 26 with the ratchet gear 8 of the rotating shaft 6 as the rotary plate cylinder C ₄ is moved forward and backward as shown in FIGS. 5 and 11. To rotate step by step. That is, according to the pitch of the ratchet gear (8) is rotated in a step (Step) step, advance one step, and when approaching the next step, the cushion cylinder (C ₅ ) is raised to the rotating plate (3 ') and braking Since the rotational inertia is forbidden, it stops at the correct point, and the second laboratory is continuously operated as described above. Therefore, the gas leak test is performed for a sufficient time for the laboratory 6 to reach the input part IN, and when the laboratory 6 reaches the input part IN, the laboratory 1 receives the specified time (30 seconds). With the test completed above, the withdrawal part (OUT) is reached, so the sealed door 10 of the test room No. 1 and No. 6 is opened, so that the gas container for leakage test and the withdrawal of the tested gas container (G) are simultaneously Will be done. At this time, when the test room No. 1 is completed and the sealing door 10 is opened after stopping at the outlet part (OUT), the roller plate cylinder (C ₇ ) acts to communicate the arm, so the roller plate 22 has a hinge pin (H). As a result, the position of the roller bottom 11 and the roller plate 22 of the examination room 9 is in equilibrium while being raised from the point of reference, thereby solving the problem of being shocked when the gas container G is drawn out. Here, when the sealed door 10 is opened, the blower 13 sucks the fresh air into the test chamber while scavenging the inside, and after the withdrawal of the gas container G, the roller plate 22 has a cylinder C ₇ . Since the sealing door 10 is easily closed and the rotating plate 3 'is rotated one step by the rotating plate cylinder C ₄ , the first state described above becomes.

The present invention has the advantage that it is useful for the stable handling of low-ignition LP gas, etc., because all mechanical operations are made by the pneumatic cylinder. In other words, the mechanical operation may overheat when the motor is used for a long time. Also, when the motor is damaged due to a short circuit or the motor is burned out due to an overload, it may ignite the leakage gas. Therefore, the risk of explosion is inherent, but when constructing the present invention and the pneumatic system, the utility is higher because there is no concern. The operation of this pneumatic system achieves the result as described above, which is systematically controlled by the central control unit (CB). In other words, the programmable controller (PC) built into the central control unit interrupts various switches by a program already inputted, and interrupts the solenoid valve in order to control the pneumatic cylinder of FIG. When the two sealed doors 10 located at the container inlet part IN and the outlet part OUT of the six closed doors 10 of) are simultaneously opened and closed, all the pneumatic cylinders of the 1 pneumatic line (Line 1) As in the embodiment of the will be done once.

EXAMPLE

When laboratory 6 is located at the container inlet (IN) and laboratory 1 is located at the container outlet (OUT),

이와같은 순으로 공압시린더가 작동한다. 이 작동은 1스텝의 작동순이며 6회 반복 동작 되었을때 1싸이클(1회전)을 완료하는 것으로 연속동작시 1싸이클에 6개의 가스용기를 검사할 수 있게 된다. 따라서 1싸이클에 72초가 소요된다고 가정하면 가스용기 하나당의 검사시간은 규정시간을 훨씬 상회하여 정확한 검사가 될수 있는 것이며, 72초에 6본씩의 가스용기를 처리하게 되므로 결국 검사속도는 12초당 1개라는 결론을 얻게 되는 것이다.

The pneumatic cylinders operate in this order. This operation is a one-step operation sequence, which completes one cycle (one revolution) when it is operated six times repeatedly, so that six gas containers can be inspected in one cycle during continuous operation. Therefore, assuming 72 cycles in one cycle, the inspection time per gas container can be more accurate than the prescribed time, and because six gas containers are processed in 72 seconds, the inspection speed is one per 12 seconds. Will be concluded.

Effects obtained by the present invention as described above,

1. A large amount of gas container leakage test can be performed in the shortest time.

2. The test is performed for a sufficient time individually so that the accuracy of the leak test can be ensured.

3. Because it is rotary type, it occupies less installation space.

4. It is continuous and automatic operation, and the convenience of the operator is promoted.

5. It is composed of electronic control system and pneumatic system, so related configuration (appearance, volume) is simple.

6. It contributes to safety management because it excludes risk factors such as overheating and short circuit.

7. No oiling factor.

8. In gas leakage alarm, the buzzer and lamp operate and are indicated by digital meter so that the gas leakage measurement can be grasped.

Therefore, the present invention is particularly bonded to a gas filling station with a large amount of shipment, and by adjusting the capacity of the gas container, the operating time of the cylinder, etc., it is possible to modify the size of the laboratory or to increase or decrease the number of the laboratory. Modifications within the technical scope are possible.
