3 and 24 are swung in the direction of approaching and separating from each other.

Since the holding claw devices 23 and 24 are symmetrical, only the left device 23 will be described. The holding claw device pivotally connects the lower ends of the left parallel links 18, 18 to the upper portion of the claw frame 23a via shafts 23b, 23b, and has a fixed claw 23c protruding substantially vertically in the lower surface of the claw frame 23a. The movable claw 2 is opposed to the fixed claw 23c.
3d, the movable claw 23d is swung with respect to the claw frame 23a via the support shaft 23e, that is, opened and closed with respect to the fixed claw 23c like scissors.
The rod of the claw opening / closing cylinder 23f supported by a is engaged with a part of the movable claw 23d.

The folding part E is provided with a holding claw device 23 for opening and closing,
The guide rod 26 is attached to a center folding frame 25 provided in a suspension frame 17 which is provided in a direction perpendicular to the holding frame 17 in a direction orthogonal to the
The two movable frames 27, 27 are swingably supported by the guide rods 26, and a center folding claw 28 is suspended from the lower surface of each of the movable frames 27. Middle folding cylinder 2 provided on folding frame 25

Reference numerals 7 and 27 denote a pair of center folding cylinders 29 and 29 provided on each moving frame so as to be opposed to each other so as to be slid while being guided by the guide rod 26 in the direction of contact and separation. , 28 are provided so as to protrude slightly below the lower ends of the fixed and movable claws 23c, 23d and 24c, 24d of the holding claw devices 23, 24.

Therefore, the dewatered screen residue is set on the guide G on the turntable T of the bagging device.
When a predetermined amount is put into the opened bag B, as shown in FIG. 1, the center folding portion E and the holding portion D are raised and lowered via the link 16 by the operation of the cylinder 13 in a standby state in which the claws are opened. It descends with 15. At this time, since the full bag B to be sealed is set at this lower position, the lifter reaches the lower end, and then, when the parallel links 18 and 19 are opened, the guide G on the turntable is opened at the notched portion. The pinching claw devices 23 and 24 are inserted. As a result, the fixed claws 23c and 24c are inserted inside the opened bag B, and the movable claws 23d and 24d face the fixed claws outside the bag B. Next, the pawl opening / closing cylinders 23f and 24f are operated to swing the movable pawls 23d and 24d toward the fixed pawl side, thereby closing between the pawls 23c and 23d and between the pawls 24c and 24d to at least open the bag mouth. Clamp in two places.

Next, when the lifting cylinder 13 is operated,
The lifting frame 15 moves up via the link 16. As a result, the bag mouth is held by the holding claw devices 23 and 24 and pulled up. Ordinarily, the lifting frame may be lowered after reaching the predetermined height, or after the bottom of the bag B is lifted by a turntable or a guide and reaches a predetermined height. This descent is preferably steep. In this case, the dewatered screen residue placed in the bag has a smaller gap than each other in the coarsely filled state, resulting in dense filling. This bag can be lifted and dropped once or twice.
Repeat the process more than once to tightly fill the bag with the screen residue. Next, when the folding cylinders 29, 29 are actuated, the moving frames 27, 27 move in a direction approaching each other, and the folding claws 28, 28 move from the open state of the solid line position to the close state of the broken line position. Become. In the opened state, the center claws 28, 28 are located outside the bag, and the holding claws 23,
24 is located at the center position, the bag mouth portion is
As shown in FIG. 10, a flat Z-shape is formed by the cooperative operation of the close movement of the holding claw devices 23 and 24.

When the center claws 28, 28 approach each other, the claw holding cylinder 22 is also operated to bring the claw holding devices 23, 24 facing left and right closer to each other. After the bag mouth is flattened and folded in this way, this portion is clamped and sealed with staples. This causes the scissors-like clamp frame 6 to advance toward the bag from the clamp standby position shown in FIGS. At this time, the opposed clamp frames 6 and 6 are open at the ends, so that the clamp frames 6 and 6 are inserted into the outside of the bag mouth portion that is flattened in a half-fold shape. When the cylinder 12 is operated, the clamp frames 6 and 6 that have been opened are closed to each other to clamp the bag mouth and are sealed by a stapler attached to the clamp frame 6. A plurality of staples are sequentially driven and sealed by operating the cylinder 8, opening and closing the clamp frame, and operating the stapler. In some cases, staples are again stapled to different heights with the clamp frame opened to a half-open state, the lifter raised, and the bag slightly raised.

Once the bag opening is sealed with staples, the lifter is once lowered to place the bag in the guide, the center folding claw is slightly opened, the movable claws of the claw clamping devices 23 and 24 are opened, and the lifter is raised. , Remove the bag. In the upper part of the lifter, the link 19 is opened, the center claws are returned to the original position, and the link 19 is returned to a closed state, that is, a standby state. The bag is sealed and placed on the table in the guide. Next, the next bag is sealed by rotating the turntable by one pitch.
