[Action]

In the automatic bulk filling apparatus of the present invention, an electric bogie equipped with a packer loaded with a paper bag or a flexible container bag (hereinafter referred to as bags) is moved to a stop device immediately below the silo, and is completely discharged to the silo discharge port. The receiving port of the packer is raised so as to fit, and comes into contact, and compressed air is introduced between the discharge port and the expansion cover from the compressed air introduction port of the discharge port. Since the expansion cover is fixed to the outer periphery of the upper and lower ends, the middle portion is in close contact with the inner peripheral surface of the receiving port outside the bulge. After that, the outlet gate (switch) of the silo is opened and loose objects are allowed to fall freely. Then, after a certain weight of loose articles has already entered the bags, the timer operates to close the discharge gate, and the filling operation is completed. Thereafter, the inlet of the packer is lowered, and the stopped electric bogie starts moving and stops at the position of the sewing machine provided in the middle of the traveling rail. In the sewing machine, the bags are lowered from the upper position to the upper end of the bags, and the bags that have been opened in a substantially circular shape pass through a pair of left and right C-shaped guides and rollers, and the bags are sealed by a pair of left and right pressing machines. State
The mating surface is sewn by a sewing machine. After this operation is completed, the electric truck moves the sealed bags to the end of the traveling rail, where it is unloaded to the carrier of a transport vehicle such as a truck and sent to the destination. The emptied electric trolley moves again, and the bags are set in an open state by the bag loading machine in front of the silo. In addition, the loading of bags may be done manually because of light labor.

It comprises a clamp mechanism for clamping and holding and an upright on the electric trolley 4 and the above-mentioned receiving port 4b and a column for supporting the clamp mechanism. An air injection nozzle for injecting air into the empty bag is attached to the lower end of the receiving port 4b. Note that the column can be inverted around a pin fulcrum near the lower end, so that it can be tilted and receded when loading and filling a full bag after filling, so that there is no problem.

Further, the control panel 8 sequentially activates the series of operation commands according to a preset program.

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

First, an empty bag is set manually at the lower end of the receiving port 4b of the packer 4a of the electric bogie 4 and fastened by the bag loading machine 7 manually or where the bag loading machine 7 is provided. The electric cart 4 moves directly below the silo 1 in a state where the air is injected into the bag and the bag is opened. Thereafter, the receiving port rises and comes into contact with the discharge port 20 of the silo 1. Then, compressed air is blown from the injection port 24, the expansion cover 22 expands, and the discharge port 20 and the receiving port 4b come into close contact with each other.

After the above-mentioned preparation work is completed, the switch 1a attached to the silo 1 is opened, and a required amount of loose objects is dropped and filled into the empty bag.
Air is removed from the filled hollow bag by a discharge pipe 1b with an air filter 1c. The switch 1a is set in advance so as to be in a closed state after a time when a substantially constant amount of capacity is filled in the bag by a timer, and the filling operation is completed. Thereafter, the electric carriage 4 is moved to the position of the sewing machine 6 with the receiving port 4b lowered, separated from the packer 4a, and loaded with bags filled on the floor of the electric carriage 4, and stopped at this position to stop the sewing machine 6
Reversely moves or the electric trolley 4 switches to the slow forward movement, and as shown in FIG. 3, the upper end of the bag passes through the guide 6a and the pair of left and right rollers 6b to be aligned with one character, and
While holding the bag mouth presser 6c at the bottom with the air cylinder 6d,
The upper ends of the two bags are sewn through the concave groove of the sewing machine 6. After the above sewing work is completed,
The electric bogie switches from the slow speed to the standard speed, moves to the end position, and stops. Thereafter, the bag on the packer 4a is transferred to a truck or other transporting machine by a winch or other cargo handling machine for shipment.

Since the automatic bulk filling apparatus of the present invention can be operated almost fully automatically, for example, as shown in FIG.
In addition, a plurality of devices can be gathered to consolidate cargo handling work and improve work efficiency.

In the present invention, the automatic bulk filling device is installed immediately below the silo 1, but it may be installed immediately below the hopper scale below the silo.
