It will be mounted on the 8.

A series of liquid material taking-out methods using the liquid material taking-out apparatus constructed as described above will be described below mainly with reference to FIG. 1 and appropriately to other drawings.

First, the drum can D containing the liquid-filled bag F is conveyed to the drum can conveyer 1 by a forklift or the like.
On the carry-in end, open the lid C, and move to the conveyor carry-out end. At the carrying-out end of the conveyor 1, the drum can D is placed on the turntable 18, and the turntable 18 is raised and rotated so that the liquid material-filled bag F in the drum can D is oriented so that the bag pull-out fitting 19 can be easily attached. To match.

When the orientation of the liquid-filled bag F in the drum can D is properly adjusted, the turntable 18 is lowered, and the bag pull-out fitting 19 is shown at the tip portion f1 of the bag F as shown in FIG. 8B. To stick. After that, the drum can D is held and fixed to the rotary frame 11 by the clamp means 14 provided on the rotary frame 11 of the drum can overturning mechanism 2, and the rotary frame 11 is rotated by 90 degrees to move the drum can D to the vertical posture of FIG. To a horizontal position.

Thus, the locking rods 19c and 19 of the bag drawing metal fitting 19 fixed to the tip portion f1 of the liquid material filling bag F.
By locking c to the locking bars 21 and 21 of both chains 20 and 20 of the bag pulling mechanism 3 and driving the chains 20 and 20, the liquid-filled bag F is pulled out from the drum can D and at the same time. The bag F is laid on the bag support 22. In this state, the liquid material outlet T at the bag tip portion f1 is connected to the suction pump 6 via the hose 5, and the bag drawing metal fitting 19 is fixed to the rear end portion f2 of the bag F. After the bag F is pulled out from the drum can D, the rotary frame 11 of the drum can overturning mechanism 2 is returned to its original position.

Thereafter, the rear end side of the liquid-filled bag F is lifted by the lift mechanism 26 as schematically shown in FIG. 1, and the U-shaped handgrip 19d on the bag pull-out fitting 19 at the rear end of the bag.
The hook K at the tip of the suspension chain J of the hoist 4 is hooked on the hoist 4, and the electric chain block is rolled up to lift the liquid material filling bag F to a required height. Then, the bag F is squeezed by the squeezing rollers 7a and 7b of the bag squeezing mechanism 8.
The suction pump 6 is squeezed between the suction rollers 6a and 7b together with the base frame 31 by sliding down from the upper end of the squeezing rollers 7a and 7b along the guide post 30 to squeeze the liquid material filled bag F with the squeezing rollers 7a and 7b. When the suction operation is performed, the liquid substance in the bag F is very effectively discharged to the liquid substance taking-out tank 37 through the hose 5 by the gravity action, the squeezing action of the squeezing rollers 7a and 7b, and the suction action of the suction pump 6. It

In this embodiment, the liquid-filled bag F lifted by the hoist 4 is sucked and discharged by the suction pump 6 while being squeezed by the squeezing rollers 7a and 7b, but the squeezing rollers 7a and 7b are not always used. It is not necessary to do so, and only suction with the suction pump 6 may be performed. However, if the squeezing rollers 7a and 7b are used, the liquid substance can be discharged from the bag F more quickly.
