When the chemical container 2 is seated inside the chemical container 5, the chemical container 5 opens the lid of the chemical container 2 and connects the coupler to the chemical container 2, Allows accepted chemicals to be supplied to chemical applications.

Referring to FIG. 16, a path to be transported when the empty chemical container 2 that has been used in the chemical feeder is discharged to the discharge unit 210 will be described.

When the used empty chemical container 2 is transported in the chemical feeder 5, the feeder car 600 is positioned in front of the chemical feeder 5, (601) of the transfer unit (600).

The conveyance car 600 on which the chemical container 2 is mounted moves to the position of the sixth connection part 340 and 440 and the chemical container 2 is moved from the conveyance car 600 to the sixth conveyance line 300, And the connection portion 340 is transferred to the sixth connection portion 440 of the fourth transfer line 400.

The chemical container 2 is conveyed along the fourth conveyance line 400 by the sixth conveyance unit 440 and the second conveyance line 200 is conveyed through the third conveyance unit 160 and 260 do. The chemical container 2 is transferred along the second transfer line 200 and is loaded on the forklift 4 through the discharge unit 210. The third transfer unit 260 is connected to the chemical container 2 through the second transfer line 200,

Referring to FIG. 17, a description will be made of a path that is transported when the chemical container 2 and the pallet 3 are inserted through the discharge portion 210. FIG.

If the chemical container 2 can not be conveyed through the input unit 110 or the first conveyance path 100, the chemical container 2 is introduced into the discharge unit 210.

The chemical container 2 of the discharging unit 210 is aligned in the second aligning unit 220 and the second inspecting unit 230 inspects the chemical information and the positional abnormality, If not, is conveyed along the second conveyance line 200. The second checking unit 230 may be provided for emergency when an abnormality occurs in the input unit 110.

The chemical container 2 having no abnormality in the second inspection part 230 is conveyed through the second connection part 150 of the first conveyance line 100 after the conveyance direction is changed by 90 degrees from the second connection part 250 And then transferred to the air shower part 310. In the air shower part 310, air is sprayed for a predetermined time to remove foreign matter from the outside of the chemical container 2 and the pallet 3.

The process of injecting the chemical container 2 having passed through the air shower part 310 into the chemical feeder 5 is the same as that described with reference to FIG.

In the above description, there is one chemical supply device 5, but a plurality of chemical supply devices 5 may be provided. When the number of the chemical supply units 5 is plural, the control unit supplies the chemical containers 2, which correspond to the chemical information required by each of the plurality of chemical supply units 5, to the plurality of chemical supply units 5 .

According to the present invention, the chemical container 2 having the chemical information required by the chemical supply device 5 can be automatically supplied to the chemical supply device 5, so that the number of operations for supplying the chemical can be reduced, The chemical can be supplied smoothly. The process of disassembling and separating the packaging of the chemical container 2 by transferring the chemical container 2 and the pallet 3 from the chemical manufacturing factory to the chemical supply device 5 without being disassembled It is possible to prevent breakage of the chemical vessel and external leakage of the chemical.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And this also belongs to the present invention.
