The bag loading machine 7 is installed immediately before the silo 1 and is set so as to hold the upper opening of the bag outside the receiving port 4b while injecting air into the empty bag at a predetermined position of the packer 4a. Device.

As described above, the packer 4a mounted on the electric trolley 4 has a receiving port 4b which moves up and down by an air cylinder, for example, and an upper end opening of an empty bag inserted into the lower end of the receiving port 4b. It is composed of a clamp mechanism that clamps and clamps, and an upright port 4b, a column that supports the clamp mechanism, and a nozzle that injects air into an empty bag.

The operation of the automatic bulk material filling apparatus of the present invention configured as described above will be described.

First, in the bag loading machine 7, air is blown into the packer 4 a of the electric cart 4 into the packer 4 a to open the bag, and then the bag is opened.
The inner peripheral surface of the upper end of the bag 100 is pressed against the outer periphery of the lower end of the reception port 4b, and a command is issued to the control panel 8 to move the electric bogie to just below the silo. Then, the inverted truncated cone-shaped receiving port 4b that can move in the vertical direction is raised, and the inner peripheral surface of the receiving port 4b is brought into close contact with the outer periphery of the discharge port 1a. At the site where the bag loading machine 7 is not installed as described above, the bag is manually received by the worker.
Set at the bottom of Thereafter, a switch (not shown) attached to the silo 1 is operated to be opened to drop and fill the empty objects in the silo 1 into the empty bag. Air is removed from the filled hollow bag by a discharge pipe 1b with an air filter 1c. The switch is previously set to be closed by the timer after the time when a substantially constant amount of the capacity is filled in the bag, and the filling operation is completed. After that, the electric carriage 4 moves to the position of the fastener closing device 6 and stops, with the receiving port 4b lowered, detached from the packer 4a, and loaded with the filled bags. As described above, the upper end of the bag is matched to one character by the bag mouth presser 51 having a pair of right and left presser plates 51a, and the fastener 100b at the upper end of the combined two bags is engaged with the chuck 54 of the closing machine 50.
