Description

Dust Collecting And Packing System}

The present invention relates to a device for collecting dust, and more particularly, to a dust collection and automatic packaging system that is connected to a dust collector that collects dust generated in manufacturing industries and automatically packs the dust into a packaging bag. it's about

In general, exhaust gas containing dust and impurities of various harmful substances is generated in a workplace of various manufacturing industries such as semiconductor and LCD processes.

Since these exhaust gases are suffocating, retardant, flammable, explosive, toxic and corrosive, they are not only harmful to the human body, but also cause environmental pollution when released into the atmosphere. A dust collection treatment and purification treatment process that lowers the concentration below the permissible concentration is absolutely necessary.

In addition, fine particles are included in exhaust gas discharged from a workplace such as a semiconductor process, and these fine particles must be removed so that they are not discharged into the atmosphere.

Accordingly, the present applicant has proposed a harmful dust sealed transport and packaging system capable of transporting fine dust in harmful gases generated in the workplace to an automatic packaging processing unit so as not to leak to the outside in Patent Publication No. 2017-0073453.

A dust treatment system that collects and treats such harmful dust is configured to transfer the collected dust from a dust collector to a dust container and then suction and treat the dust from a dust packing machine.

For example, as shown in FIG. 1, in the conventional dust treatment system, two dampers 2a and 2b are continuously disposed at the lower part of the cyclone dust collector 1, and dust is disposed at the lower part of the lower damper 2b. A packaging bag (4) and a dust container (3) for collecting are installed.

In this dust treatment system, the dust introduced through the upper inlet 1a of the cyclone dust collector 1 is accumulated on the lower part and the upper damper 2a of the cyclone dust collector 1, and the dust accumulated in the lower part is transferred to the lower dust container. If you want to discharge in (3), close the inlet (1a) and outlet (1b) of the cyclone dust collector (1), open the upper damper (2a) and the lower damper (2b) sequentially to drop the dust to the dust box It is collected in the plastic packaging bag (4) accommodated in (3).

However, when the inlet 1a and the outlet 1b of the cyclone dust collector 1 are simultaneously closed in the process of collecting dust in the conventional dust treatment system, a low vacuum is formed inside the cyclone dust collector 1, and the upper damper Even if (2a) is opened, the dust accumulated in the lower part of the cyclone dust collector 1 does not fall smoothly to the lower side and remains, causing a problem in that the dust collecting function is significantly deteriorated.

In addition, as a low vacuum is formed inside the cyclone dust collector 1, a problem occurs in that the packaging bag 4 in the dust container 3 is sucked up. To prevent this, a wire net ( A separate structure such as 7) is inserted. This wire net (7) is cumbersome because the operator must withdraw it from the inside of the packaging bag (4) when packing the bag (4), and the dust during the drawing operation is removed from the outside. It may leak out and cause contamination.

In addition, when the lower damper 2b is opened, the vacuum state in the upper cyclone dust collector 1 is broken, and the air rapidly expands, resulting in a phenomenon in which dust rapidly expands right below the lower damper 2b. Due to this, dust leaks between the band 6 connecting the dust container 3 and the damper housing of the lower damper 2a, resulting in contamination. This leakage of dust contaminates workers when packing the packaging bag 4, deteriorates the working environment, and causes a problem of increasing difficulty in packaging.

In addition, since the conventional dust treatment system requires a worker to manually pack the packaging bag, the efficiency of the packaging operation is low, and there is a high possibility of contamination with dust during the packaging process.

In addition, in the conventional dust treatment system, dust accumulates on the packing material that seals between the upper surfaces of the dampers 2a and 2b and the dust outlet at the bottom of the cyclone dust collector 1 and hardens, resulting in dust due to poor packing. There is also the issue of leakage.

In addition, an exhaust filter 65 for preventing dust from leaking out to the outside may be additionally installed in the exhaust line 76 .

The first control valve 73, the second control valve 75, and the third control valve 77 may be solenoid valves operated by electricity.

A detailed description of the operation of the dust collection and automatic packaging system configured as described above is as follows.

Before starting the dust collection operation, the operator fixes the upper end of the packaging bag (B) to the chuck 65 while the chuck 65 is moved downward and separated from the damper unit 50, and the chuck lifting unit ( 66) is operated to move the chuck 65 upward to bring it into close contact with the lower end of the damper unit 50.

At this time, since both sides of the packaging bag (B) are folded and contracted, the first control valve (73) is opened and the air pump (71) is operated to ensure smooth inflow of dust into the packaging bag (B). Air is supplied to the inside of the damper unit 50 through (72). The air supplied into the damper unit 50 is supplied into the packaging bag (B) through the upper entrance of the packaging bag (B), so that the packaging bag (B) can be automatically inflated.

When the packaging bag (B) is mounted on the dust packing unit (60), the third dust outlet (42b) is closed by the first damper (51), and the dust collecting operation is ready to be started.

The dust introduced through the upper entrance 11 of the dust collector 10 is collected in the lower part of the dust collector 10 and accumulated on the dust collector damper 20. When a predetermined amount of dust accumulates under the dust collector 10, the inlet 11 and the outlet 12 of the dust collector 10 are closed, and the dust collector damper 20 is opened. At this time, the inside of the dust collector 10 is in a low vacuum state, and the inside of the dust container 30 under the dust collector damper 20 is also in a low vacuum state, so that the dust may not fall smoothly to the lower side.

At this time, as described above, when the vacuum break control valve 32 is opened, the outside air is introduced into the dust container 30 through the ventilation hole 31, and the vacuum in the dust container 30 is broken to prevent dust collector 10 ) The dust can fall smoothly into the dust container 30.

As the dust collector damper 20 is opened, the dust that has fallen to the bottom of the dust container 30 is transported toward the second dust outlet 35 by the first screw unit 34.

And when the vacuum motor 43a of the vacuum generator 43 of the vacuum dust collector 40 operates, the dust transferred to the vicinity of the second dust outlet 35 of the dust container 30 passes through the suction pipe 44 to the dust collection chamber ( 42) After being introduced into the inside, the dust falls and accumulates in the lower part of the dust collection chamber 42 by the principle of cyclone dust collection, and after the air and fine dust flow into the filter 48, the fine dust passes through the filter 48 Filtered and only the air is discharged to the outside through the vacuum generator (43). At this time, the third dust discharge port 42b of the dust collector main body 41 is closed by the first damper 51, so that the suction force can be transmitted to the dust container 30 only through the suction pipe 44.

When dust is accumulated inside the dust collection chamber 42 and the level sensor 49 detects the height of the dust, the operation of the vacuum generator 43 is stopped, and the first damper 51 moves backward to open the third dust outlet 42b. open up Then, the second damper 53 is rotated by the operation of the damper operating motor 54 to open the lower end of the damper unit 50 .

When the first damper 51 and the second damper 53 are opened, power is applied to the second screw motor 45b of the second screw unit 45 to rotate the second screw 45a, thereby forming a dust collection chamber 42 ) The dust collected in the lower part is transferred to the third dust discharge port 42b and discharged to the outside.

The dust discharged through the third dust outlet 42b falls downward through the damper unit 50 and flows into the packaging bag B through the upper entrance of the packaging bag B. At this time, the third control valve 77 is opened so that the air in the packaging bag (B) and the damper unit 50 can be naturally discharged to the outside through the exhaust line 76, so that the inside of the packaging bag (B) Dust inflow can be made smoothly.

Dust is introduced into the packaging bag (B), and the turntable (61) and the load transfer table (62) descend with respect to the base member (63) by the load of the packaging bag (B), and the weight measurement sensor (69) collects the dust. The weight of the dust is measured. When the weight of the packaging bag (B) measured by the weighing sensor 69 exceeds a predetermined value in the control unit (not shown) or when a certain time elapses after dust collection, the third dust is collected by the first damper 51. The outlet 42b is closed.

And when the second control valve 75 is opened and the air pump 71 is operated in a state where the first control valve 73 is closed, the air inside the packaging bag (B) moves through the damper unit 50 and the vacuum line ( 74), and the packaging bag (B) shrinks. When the packaging bag (B) shrinks in this way, it becomes easy for the operator to separate the packaging bag (B) and transport it to the outside.

When the air inside the packaging bag (B) is discharged and contraction is completed, the second control valve 75 is closed and the operation of the air pump 71 is stopped. And the second damper 53 closes the lower end of the damper unit 50.

Subsequently, power is applied to the rotation motor 64 of the rotation unit to rotate the turntable 61 in one direction. As the turntable 61 rotates, the top of the packaging bag B, whose top is fixed to the top of the damper unit 50 by the chuck 65, is twisted and the entrance to the top of the packaging bag B is blocked. Then, by operating the binder forward/reverse machine 68 of the binding unit to bring the binder 67 closer to the twisted part of the top of the packaging bag (B), and then operating the binder motor (67a) to the packaging bag (B) with the binder (67). ), the packaging bag (B) is automatically packed.

Then, the chuck lifting unit 66 operates, the chuck 65 descends and is separated from the damper unit 50, and the operator separates the top of the packaging bag B from the chuck 65 and transfers it to a designated place for processing do.

As described above, the dust collection and automatic packaging system of the present invention can smoothly transport the dust without leakage or rapid expansion of the dust in the process of transferring the dust collected in the lower part of the dust collector 10 to the dust container 30. In addition, the dust collected in the dust container 30 can be smoothly transported and collected into the packaging bag B using the vacuum dust collection unit 40.

In addition, after the inside of the packaging bag (B) is filled with dust, the packaging bag (B) is rotated in one direction by a set number of rotations to twist the upper end, and then the twisted upper end can be automatically bound and packed. It is not necessary to bind the top of the packaging bag. Therefore, it is possible to prevent workers from being contaminated with dust during the process of binding and discharging the packaging bag (B), and it is possible to obtain an advantage of significantly improving the efficiency of the packaging and discharging operation of the packaging bag (B).

In particular, in a state where the upper end of the packaging bag (B) is fixed with the chuck (65) for smooth inflow of dust into the packaging bag (B), air is introduced into the damper unit (50) through the air supply line (72) so that the packaging bag ( B) can be automatically inflated, and after the packaging bag (B) is filled with dust, the air inside the packaging bag (B) is removed using the air pump (71) and the vacuum line (74) to remove the packaging bag (B). The volume can be minimized by shrinking. Therefore, it is easier for the operator to separate the packaging bag (B) from the dust packaging unit 60, and since the volume of the packaging bag (B) can be reduced, an advantage in disposal of the packaging bag (B) can be obtained.

The dust collection and automatic packaging system of the present invention may be fixedly connected to the dust collector 10, but otherwise, the dust collection and automatic packaging system is configured on a mobile cart equipped with wheels to configure one dust collection and automatic packaging system. All or part of the elements may be moved and connected to several dust collectors (eg, cyclone dust collectors) to collect and pack dust. For example, components such as the vacuum dust collection unit 40, the damper unit 50, the dust packaging unit 60, and the air pump 71 of the dust collection and automatic packaging system can be used by mounting them on a mobile cart equipped with a plurality of wheels. can
