There are two types of cam followers 474 and 476, one for opening the shutter 47 and the other for closing the shutter 47. Each time the moving cam of the shutter 47 comes into contact with the opening cam follower 474, the shutter 47 opens and the powder drops from the basket 46. When the supplied and further opened shutter 47 moves, the shutter 47 contacts the closing cam follower 476 so that the shutter 47 closes the lower end opening of the flange 46 again.

  When the filling of the powder is completed, the movable bar 28 returns from the vertical position to the horizontal position. The chute 15 returns from the lowered position to the raised position. Thereby, the film 12 continuously provided with the respective bags 44 filled with the powder is taken out from the filling mechanism 17. Thereafter, the upper edge (bag opening of the bag 44) of the film 12 is sealed by the upper edge sealing device 19. Further, the cutter device 20 is cut at each width seal portion or perforated there, and then discharged to a discharge device (not shown).

  FIG. 7A shows a state where the rod 101 described in the first embodiment is attached to the through hole of the rod rotating plate 450, and FIGS. 7B and 7C show the second embodiment. 5 shows a state in which the rod 102 described in the above item is attached to the through hole of the rod rotating plate 450.

  As shown in FIG. 7A, the saddle rotating plate 450 rotates in the direction of the arrow (counterclockwise direction) by the rotation of the rotating shaft 250. When attaching the bag 102 to the bag rotating plate 450, as shown in the drawing, the rotation angle of the chute 15 is about 30 degrees in the counterclockwise direction (depending on the number of divisions of the bag), that is, in the opening of the bag 44. At the position where the cylindrical lower portion 33 is inserted, the flange 101 is attached so that the first feeding path 110a of the flange 101 is positioned on the downstream side in the rotation direction of the flange rotating plate 450. This is because the powder in the first feeding path 110a of the rod 101 is dropped and supplied at a predetermined rounding position, and then the powder in the second feeding path 110b is dropped and supplied at a predetermined rounding position. The mechanism and operation for dropping and supplying the powder in the basket 101 will be described below.

  The opening / closing mechanism of the shutter 47 is the same as the mechanism described in FIG. As a mechanism for opening and closing the shutter 47, a projecting cam (not shown) is provided on the lower surface side of the shutter 47 as shown in FIG. As shown in FIG. 7A, an opening cam follower 474 directed toward the saddle rotating plate 450 side is provided at a position where the turning angle is 120 degrees in the counterclockwise direction.

  When the opening cam follower 474 comes into contact with the cam 471 of the shutter 47a that is moved by the rotation of the eaves rotating plate 450, the shutter 47a rotates clockwise about the shaft 475.

  As shown in the figure, as the shutter 47a rotates in the clockwise direction, the right end of the shutter 47a comes into contact with the left end of the adjacent shutter 47b, and the shutter 47b is rotated the same time as the shutter 47a by the shutter 47a. Extruded in the direction of movement. As a result, the shutter 47b rotates clockwise about the shaft 475 and is completely separated from the lower end opening of the flange 101. Thus, in the filling and packaging apparatus according to the present invention, the powder supply is completed at the position where the turning angle is about 90 degrees in the counterclockwise direction.

  Subsequently, when the shutter 47b is pushed out by the shutter 47a in the same rotational direction as the shutter 47a, the right end of the shutter 47b and the left end of the adjacent shutter 47c come into contact with each other, and the shutter 47c becomes the shutter 47b. Thus, it is pushed out in the same rotational direction as the shutters 47a and 47b. At this time, the shutter 47c is separated from the basket 101 and only the first feeding path 110a of the basket 101 is released (the second feeding path 110b is closed by the shutter 47c). As described above, in the filling and packaging apparatus according to the present invention, the powder supply operation is started at a position where the turning angle is about 60 degrees in the counterclockwise direction (depending on the number of divisions of the basket).

  As shown in the figure, the shutter 47c does not rotate to a position where the shutter 47d can be pushed out. That is, at the position where the rotation angle is about 30 degrees in the counterclockwise direction (depending on the number of divisions of the ridge), the lower end opening of the ridge 101 is completely closed by the shutter 47d, and the powder is held in the ridge 101. Note that the rotation mechanism of the shutter 47 for dropping and supplying the powder in the basket shown in FIGS. 8 and 9 is the same as the mechanism described in FIG.

  A state in which the powder is filled in the bag will be described with reference to FIG. As shown in FIG. 7 (a), the rod rotating plate 450 rotates in the direction of the arrow (counterclockwise direction), and the rod 101 moves to the powder supply start position (the rotation angle is 60 degrees counterclockwise). When it arrives, the shutter 47 is separated from the bag 101, and the upper opening of the chute 15 and the first feeding path 110a communicate with each other. Then, the powder is dropped and supplied to the bag 44 through the chute 15 from the first feeding path 110a of the basket 101.

  As shown in FIG. 10, compared to the conventional technique in which the entire amount of powder from the basket is dropped and supplied to the bag 44 at a time, in the example of FIG. Since it is supplied by dropping, the impact when the powder falls is halved. At this time, the powder 44 slightly rises in the bag 44, but very little powder is scattered outside the bag.

  When the reed rotating plate 450 further rotates in the direction of the arrow (counterclockwise direction) and the reed 101 arrives at the powder supply start position (position at which the circulatory angle is about 90 degrees in the counterclockwise direction), the shutter 47 Further away from 101, the upper opening of the chute 15 communicates with the first feeding path 110a and the second feeding path 110b. Then, the powder is dropped and supplied to the bag 44 through the chute 15 from the second feeding path 110 b of the basket 101.

  At this time, since the powder first dropped and supplied from the first supply path 110a is stored in the bag 44, the powder stored previously is transferred from the second supply path 110b into the bag 44. Acts as a cushioning material to relieve shock when dropped. As a result, it is possible to effectively suppress the rising of the powder.

  Thereby, accurate powder supply in which the amount of powder actually filled in the bag 44 matches the measured value can be performed while preventing the working environment from deteriorating. The above-mentioned effect obtained by dividing and supplying the powder in the bag 101 to the bag 44 in stages is the ratio of the passage sectional area of the powder in the first feeding path 110a and the second feeding path 110b. Is, for example, 1: 9, 2: 8, 3: 7, 4: 6, or when the kite described in the second, third, fourth, and fifth embodiments is attached to the kite rotating plate 450 However, it can be obtained similarly.

  Furthermore, by dropping and supplying the powder in the bag 101 to the bag 44 in stages, for example, when powder that has low fluidity and easily causes a bridge phenomenon is dropped and supplied to the bag 44, The clogging of the powder in the chute 15 interposed therebetween can be suppressed.
