Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supplies an upper filling material so that a large amount of filling material such as powder or granules can be favorably filled until it fills the flexible bag by supporting the opening side of a large flexible bag. The present invention relates to a filler supply device for a long and flexible bag that can be supplied from a section.

[0002]

2. Description of the Related Art Conventionally, as seen in Japanese Utility Model Publication No. Sho 61-22801, a flexible bag of this kind is formed in a long size for filling a large amount of powder or granular material of 500 kg to 1 ton. In addition, it is known to attach a large frame plate that can be folded from the center to the opening side peripheral edge of the flexible bag so that the long flexible bag can be favorably supported when the filler is supplied from above.

[0003]

However, if such a frame plate is attached to each flexible bag, the cost will be considerably increased and the cost will be high, and the handling will be inconvenient if the large frame plate is attached. Further, there is a problem that a device for folding the frame plates after the filling is required, which complicates the supply device and increases the equipment cost.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves such a problem and provides a simple structure capable of favorably supporting a long and large flexible bag and effectively supplying a filling material, and can be suitably implemented. Therefore, the tubular body is hung from the central portion of the filler supply section to form a filling nozzle, and a ring-shaped projecting portion is fixedly provided on the outer periphery of the tubular body. The entire peripheral edge is configured to have a retractable ring such as a rubber ring, which can be shortened to be shorter than the outer peripheral length of the tubular body. Fold back stitching, form another ring-shaped protrusion below the protrusion at the lower part of the filling nozzle cylinder, or fill nozzle with a flexible bag removed from the filler supply part. The collection conveyor, nozzle pool device, and flexible bag An empty bag supply device that supplies nozzles and an empty bag pool device that is equipped with a flexible bag can be connected in a circulating manner, and in the empty bag supply device, a flexible bag can be attached to the filling nozzle when lowered by an elevating device. In the empty bag pool device, a plurality of pooled parts can be freely engaged with and disengaged from a stopper device, and the one at the tip can be sent out to the filling material supply side by a sending device.

[0005]

Therefore, when the expansion ring is expanded with both hands to fit the peripheral edge of the opening of the large flexible bag from below the tubular body, and when the expansion ring is released in the upper direction of the protrusion, the expansion ring shrinks. The long flexible bag can be properly attached to the filling nozzle so that it does not fall off by engaging above the protruding portion, and below the discharge of the filler supply unit,
It is possible to effectively supply the filling material while mounting the filling nozzle and supporting the peripheral surface of the opening below the protrusion.After the filling, if only the flexible bag is lowered, the expansion ring rides over the protrusion and slides down. The opening of the bag can be automatically and easily removed from the cylinder.
