After the handle 100c is grasped, the fastener 100b is fully closed by retreating the air cylinder 59. 3 (a) and 3 (c) show the fastener in a fully closed state.

The operation of the thus configured bulk filling apparatus of the present invention will be described.

First, the electric cart 4 is moved to a predetermined stop position just before the silo and stopped. Next, the suction plate 72b of the empty bag removing machine 70 is brought into contact with the uppermost empty bag among the empty bags stacked in the empty bag storage 60 (as shown in FIG. 4 (a)). After that, when the hydraulic cylinder 79 is driven up by about 50 cm, the empty bag is in the state shown in FIG. 4 (e). Then, the hydraulic cylinder 74a is advanced, and the rubber bag 75d of the empty bag enclosing machine 75 is lifted and inserted into the substantially triangular empty bag inlet. Further, while stopping the suction of the suction grooves 72z, 72z shown in FIG.
When a predetermined volume of compressed air of a predetermined pressure is sealed in 5d, the rubber bag 75d and the empty bag inlet 100b are in close contact with each other and become circular (fourth).
Fig. (F).

After this state is completed, the compressed air of a predetermined pressure appropriately selected from a range of, for example, about 0.5 to 3 kg / cm ² is filled into the empty bag from the nozzle 75c through the flexible tube 75f to inflate the empty bag. State. Next, the rotation of the reduction motor 78 causes the empty bag or the empty bag enclosing machine 75 to stand upright. Thereafter, the lever 74 is rotated 90 ° horizontally by the rotation of the reduction motor 76, and the empty bag is transferred from the point A to the point B in FIG. 4 (a), so that the empty bag is raised on the electric carriage 4. . At this time, the vertical adjustment is performed by moving the hydraulic cylinder 79 forward and backward as necessary.

Further, at point B, after the hydraulic cylinder 82 of the holding machine 80 is advanced to bring the arm 81 into contact with the empty bag inlet 100a, the outer surface of the empty bag is sucked by a vacuum pump via the flexible pipe 84. The arm 81 is sucked and held. Thereafter, the compressed air in the rubber bag 75b of the air filling machine 75 is exhausted, moved upward and separated, and returned to the state shown in FIG. 4 (a).
In this way, with the empty bag held upright by the holding device 80 mounted on the electric trolley 4, the electric trolley 4 is moved to just below the silo and stopped.

The state shown in FIG. 6 immediately below the silo is as shown in FIG.
The air cylinder 47b is moved down and fitted, and the air cylinder 47b is actuated so that the empty bag inlet 100a and the bag mouth mounting opening 48c are gripped tightly by the clamp 47 (the state shown in FIG. 7).

Next, the upper receiving port 48a is raised and brought into close contact with the discharge port 1a. After the above preparation, the opening and closing valve of the silo is opened, and when the required time elapses, the bulk material is fully filled. At this time, the holding device 80 is separated and retracted. Eventually, the full bag stands upright on the floor of the electric cart 4. The air in the bag being filled is an air tube
Escape to the outside via 1b and filter 1c. Thereafter, the upper receiving port 48a is lowered, the diameter of the clamp 47 is increased and the bag 47 is detached, and then the bag mouth mounting port 48c is raised. When the mounting column 45 is tilted to the front as shown by the dashed line in FIG. 10 bags weighed
0 and the packer 40 are unrelated.

Next, the electric trolley 4 moves forward to the position of the fastener closing device 6, and the bag mouth is matched with a single letter by the bag mouth presser 51, and the fastener 100b is closed. When the closing operation is completed, the closing machine 50 moves upward and retracts.

When transferring the full bag to the fastener closing device, the holding device 80 is operated again until the bag closing device 80 reaches the fastener closing device in order to prevent the bag inlet 100a from being collapsed (suction of the bag inlet side). May be.

Thereafter, the electric carriage 4 moves to the final cargo handling station 9, where the filled bags are unloaded and carried to the destination.

The above operations are arranged as shown in FIG.

In the closing operation by the fastener closing device 6, the electric bogie 4 stops and the closing machine 50 moves in the reverse direction. However, after being gripped by the chuck 54, the electric bogie 4 is moved forward at a very low speed, and the closing machine 50 is stopped and closed. Good. In this case, air cylinder 59
May be omitted.

The automatic bulk material filling device 2 of the present invention can automatically fill the empty bag set in the packer 40 with the bulk material, and can perform almost fully automatic operation such as a closing operation of a fastener of the filled bag. Simultaneous cargo handling is also possible, so that cargo handling can be centralized and work efficiency can be improved. Also,
Since the container is a bag with a fastener, it can be used any number of times as long as the bag is not damaged.

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

The control panel 8 can execute the operation, stop, and sequential activation of the above-described various power means, and can perform automatic operation by program control.

In the embodiment of the air filling machine 75 of the present invention, a rubber bag which expands and contracts by filling and discharging compressed air is used. In addition, a forward / backward movement of an umbrella-shaped type or a truncated cone type is used. Type.

[Effects of the Invention] As described above, according to the automatic bulk filling apparatus of the present invention, even if the empty bag has no rigidity and is soft and has no hanger, it does not have a hanging hand. ,
Since this can be automatically attached to the silo discharge port, it is possible to load empty bags, fill loose items, seal the inlet, transfer, and cargo handling almost completely automatically with only a few surveillance personnel. In addition, the work efficiency can be improved by consolidating a plurality of units, and a significant reduction in cargo handling costs can be achieved. Further, the running cost of the container can be reduced by repeatedly using bags with fasteners.
