In addition, the second elevating unit 220 of the outlet unit 1-2 has the same configuration as the first elevating unit 120 of the inlet unit 1-1 or has at least some components including a transfer member in common. It may include.

A chemical container automatic transfer method according to the present invention will be described with reference to FIGS. 3, 5, 6, 8, and 9.

First, the preparation process for putting the chemical container 2 into the inlet 1-1 will be described.

The operator loads the pallet 3 loaded with the chemical container 2 on the fork 4a of the forklift 4 and arrives in front of the pallet feed guide 10, and the feed mode switch provided on the operation panel for input / discharge. Press. When the lamp of the input mode switch is in a flashing state, the input mode state is maintained.

In this state, the operator checks the lighting color of the first lamp unit 22, and if it is green, determines that the lamp is in an injectable state, the operator presses the shutter release switch (not shown) of the shutter unit 20 to press the shutter 21. Open it. In this case, when the lighting color of the first lamp unit 22 is yellow or red, the shutter 21 is not opened even when the shutter opening switch is pressed.

When the shutter 21 is opened, the operator drives the forklift 4 to move forward. In this case, even if the forklift 4 is detected by the input detection sensor 23, the control unit controls the normal input without determining that the abnormal situation.

When the operator drives the forklift 4 to move forward, the state of FIG. 5 is obtained. That is, the chemical container 2 is mounted on the pallet 3, and the pallet 3 is loaded on the fork 4a of the forklift 4.

When the forklift 4 is further advanced in the state of FIG. 5, as shown in FIG. 6, the pallet 3 enters the area of the input unit 110.

As such, when the pallet 3 enters the area of the input unit 110, when the front end of the pallet 3 is first detected by the first detection sensor 114-1, the pair of second stoppers is detected. The control unit 113-2 protrudes in an inner direction that faces each other.

When the forklift 4 is further advanced, the second sensing sensor 114-2 detects the front end of the pallet 2. When the front end of the pallet 2 is detected by the second sensor 114-2, blue light is turned on by the second lamp unit 117 as an example, and in this case, the pair of first stoppers 113-1 ) Protrude in an inward direction facing each other.

When the first stopper 113-1 protrudes inward, a color different from the blue color (for example, white) is turned on in the second lamp unit 117.

When the operator checks the blue and white lighting of the second lamp unit 117, the fork lifter 4a of the forklift 4 is lowered so that the bottom surface of the pallet 3 is formed of the transfer members 111a, 111b, and 111c. Make sure that it rests on the top. In this case, the height at which the fork 4a is raised and lowered is the bottom 11 or the conveyance when the pallet 3 is spaced apart from the top 11 or the top of the conveying members 111a, 111b, and 111c and the forklift 4 moves forward and backward. Since the height does not come into contact with the upper ends of the members 111a, 111b, and 111c, in this case, the height difference is very small compared to the difference between the first height and the second height.

When the chemical container 2 and the pallet 3 are seated on the conveying members 111a, 111b, and 111c, the operator reverses the forklift 4. In this case, since the first stopper 113-1 protrudes inwardly, the pallet 3 is moved by the first stopper 113-1 even if the pallet 3 retreats with a predetermined distance when the fork 4a is retracted. The locking is prevented from further reversing, and the fork 4a comes out of the pallet 3.

Even if the fork 4a is pulled out of the pallet 3 by the reverse of the forklift 4, the fork 4a is detected by the first detection sensor 114-1, and thus the pallet 3 is detected. The first detection sensor 114-1 that was present maintains the detection state of the fork 4a.

Thereafter, when the forklift 4 is further retracted, the front end of the fork 4a is out of the detection range of the first detection sensor 114-1, so that the control unit has no detection object in the first detection sensor 114-1. Will be judged.

As such, when the controller determines that there is no object to be detected by the first detection sensor 114-1, the controller controls to close the shutter 21 provided at the rear of the input unit 110. If the object is detected by the input sensor 23 while the shutter 21 is closed as described above, the controller stops the operation of the transfer member for transferring the chemical container 2.

When the shutter 21 is closed, the alignment driving units 115-1 and 115-2 are driven so that the pair of alignment members 116-1 and 116-2 pushes both sides of the pallet 3 toward the center to align the pallet 3. To be done.

When the pallet 3 is aligned, the alignment members 116-1 and 116-2 return to their original positions, and the first and second stoppers 113-1 and 113-2 protrude from each other. Return to home position.

Then, the conveying members 111 (111a, 111b, 111c) of the feeding unit 110 is driven, and as shown in FIG. 8, the chemical container 2 and the pallet 3 are moved to the first lifting unit 120. It enters and is seated on the conveyance member 121 of the first elevation part 120 which was at the first height.

When the chemical container 2 and the pallet 3 are seated on the conveying member 121, the lifting drive unit is driven to move the conveying member 121 loaded with the chemical container 2 and the pallet 3 to a second height. Raise.

When the conveying member 121 is raised to the second height, the conveying member driving part of the first elevating part 120 is driven to rotate the conveying member 121. In this case, the transfer member provided in the first inspection unit 130 is also driven to rotate.

When the transfer member 121 is rotated as described above, the chemical container 2 and the pallet 3 are transferred from the first lift unit 120 to the first inspection unit 130.

Then, the first inspection unit 130 is inspected for chemical information and position abnormalities. If there is no abnormality as a result of the inspection, it is transported along the first transfer line 100, and if an abnormality is detected, an alarm is generated to allow the operator to reconfirm directly, and as a result of the recovery, the chemical container 2 and the pallet 3 are recovered. If it is determined to be transferred to the first transfer line connection unit 140 to the second transfer line connection unit 240, and transported to the discharge unit 210 along the second transfer line 200 and recovered to the forklift (4) do.
