The striking plate 507 is rotatably provided on a fixed frame 503 by a shaft 508, and a spring 509 is provided at a lower end portion thereof. , The striking plate 507 is always biased inward. Further, a cam contact piece 510 is integrally formed on the striking plate 507, and an eccentric cam 511 is provided in contact with the cam contact piece 510.

Below the striking plate 507, there is provided an air blowing upper and lower pipe 512 and an air exhaust box 513 fixed to the outer periphery of the lower portion thereof. The air blowing upper and lower pipes 512 are connected to a blower 515 through a wind blowing corrugated pipe 514 to discharge the air. The wind box 513 is connected to the dust collecting device 517 via the exhaust pipe 516. A parallel movement mechanism 518 is connected to the exhaust box 513.

In order to perform air cleaning of the packaging bag 100 with the air cleaning device 500 as described above, the straight-conveyor 310 feeds the base 200 onto the conveyor 504 and locks it with the stopper 516, as shown in FIGS. Set to the state shown. In this state, the air cylinder 506 is operated to hold the tip of the packaging bag 100 by the holding piece 505. Next, the motor 519 is operated to rotate the rotary frame 501 by 180 degrees, and then the parallel movement mechanism 518 is moved upward to insert the blower up / down pipe 512 into the tubular portion 201 of the mouthpiece 200 and eject The wind box 513 is tightly attached to the flange 202 of the base 200, and the state shown in FIGS. 10 and 11 is obtained.

Then, the blower 515 blows air into the packaging bag 100 through the blowing flexible pipe 514 and the blowing upper and lower pipes 512, and the eccentric cam 511 is rotated to push the cam contact piece 510 downward to wrap the striking plate 507. After separating from the bag 100, the hitting plate 507 is rapidly rotated in the direction of the packaging bag 100 by the spring 509, and the outer surface of the packaging bag 100 is hit by the hitting plate 507.

Therefore, the packaging bag 100 is hit by the hitting plate 507 to drop the feed adhering to the inner surface, and the shaken feed is discharged by the air blown from the blower / upper pipe 512 to the exhaust box 513 and It is discharged to the dust collecting device 517 via the air discharge spiral pipe 516.

After the feed and the like adhering to the inside of the packaging bag 100 are discharged in this way, the air blowing upper and lower pipes 512 are extracted from the packaging bag 1 and the rotating frame 501 is rotated 180 degrees again to return to the original state. Then, the nipping of the nipping piece 505 is released, the stopper 520 is released, and the ferrule 200 is sent to the linear conveyor 310.

As shown in FIG. 12, the filling device 600 is provided with a hopper 601 and an expandable tube 602 that is slidably expandable and contractable at the lower end of the hopper 601 and a flexible pipe is provided outside the expandable tube 602. 603 is provided. A flange 604 with which the cap 200 abuts is provided at the lower end of the flexible tube 603, and is vertically movable by an air cylinder 606. The middle of the expansion tube 602 is fixed to this flange 604, and the rest protrudes downward. It is configured.

A space 615 is formed between the flange 604 and the expansion tube 602, and an exhaust pipe 605 is connected between the upper end of the flexible tube 603 and the expansion tube 602. It is connected to a dust collector (not shown). A base up cam 616, which is an eccentric cam that pushes up the base 200, is provided near the bottom of the flexible pipe 603, and a base up air cylinder 617 that rotates the cam 616 is connected to the base up cam 616. . Furthermore, a stopper air cylinder 618 for locking the base 200 is provided. Further, an air cylinder 607 for rotating the holding plate 207 of the mouthpiece 200 to release the packaging bag 100 is provided.

Below the hopper 601, an elevating platform 608 is provided which can be raised and lowered by a lazy tong mechanism, and a slat conveyor 609 is provided on the elevating platform 608. Further, a slat conveyor 610 is provided adjacent to and located between the uppermost point and the lowermost point of the lifting platform 608.

Further, in the linear conveyor 310 on the carry-in side, similarly to the attachment portion 400, an air cylinder 611 for a stopper, a stopper arm 612, and locking pieces 613, 614 for sending the mouthpiece 200 intermittently at a predetermined interval. Is provided.

In order to fill the packaging bag 100 with the feed using the filling device 600 as described above, first, the elevating table 608 is located at the lowest point, and the telescopic tube 602 and the flexible tube 603 are located above. In this state, the stopper air cylinder 611 is operated to feed the base 200 and lock it on the stopper air cylinder 618. Next, the cap-up air cylinder 617 is operated to rotate the cap-up cam 616 so that the cap 200 is floated from the straight conveyor 310, and then the air cylinder 606 is operated to lower the flexible pipe 603 to lower the flange. The 604 is brought into close contact with the flange 202 of the base 200. Then, the expansion tube 602 is pulled by the flange 604 and descends so that the lower part enters the base 200.

Then, after raising the elevating platform 608 to a predetermined height, the hopper 601 is opened to feed the feed into the packaging bag 100. At this time, the air in the packaging bag 100 passes through the space 615 between the flexible tube 603 and the expansion tube 602 and is exhausted to the external dust collector via the exhaust tube 605.

When the packaging bag 100 is thus filled with the feed, the air cylinder 607 is operated to open the holding plate 207 and release the packaging bag 100. Then, the packaging bag 100 is placed on the slat conveyor 609, the height of the slat conveyor 609 is matched with that of the slat conveyor 610, and then the fastening string 103 is bound to complete the packaging with the packaging bag 100. Then, the packaging bag 1 is sent to the slat conveyor 610.

FIG. 14 is a plan view of a filling portion of another embodiment of the filling apparatus for powder and granular material packaging bags according to the present invention. In this figure, reference numeral 900 denotes a packaging bag shaping device that blows air into the packaging bag 100 sent to the filling device 600 to easily fill the feed, and the packaging bag shaping device 900 is provided with a blower blower 901. A connecting portion 903 is connected to the blower blower 901 via a blower pipe 902. The connecting portion 903 is configured to be connectable to the mouthpiece 200 that has been loaded.

In order to shape the packaging bag 100 with the packaging bag shaping device 900 as described above, first, the coupling portion 903 is coupled to the mouthpiece 200 to which the packaging bag 100 has been conveyed, and then the packaging bag 100 is wrapped with the blower blower 901. Blow air into the bag 100. Then, the packaging bag 100 is inflated by being filled with air, and is in a state substantially the same as the state in which the feed is filled. In this state, the connecting portion 903 is detached and sent to the adjacent filling device 600. In the filling device 600, since the packaging bag 100 is inflated in advance, it is possible to fill the feed very smoothly without resistance.
