  The packaging bag supply device 9 is for supplying the packaging bag A to the suction conveyor 2, and as shown in FIG. 1, the bag supply conveyor 10 for conveying the packaging bag A, and the packaging bag A from the bag supply conveyor 10. A packaging bag transport device 11 is transported to the suction conveyor 2 one by one.

  As shown in FIG. 4A, when the packaging bag A sequentially conveyed by the bag feeding conveyor 10 is detected by contacting the tip detection sensor 21, as shown in FIG. 10 stops. After the bag is detected, the suction cup 23 is lowered by the cylinder 22 attached to the electric actuator and pressed against the packaging bag A (FIG. 4B). Next, the packaging bag A is lifted by the cylinder 22 while being sucked by the suction cup 23 (FIG. 4C). In this state, the packaging bag A is moved horizontally by the electric actuator and transferred to above the suction conveyor 2 (FIG. 4D). Thereafter, the suction is released and the packaging bag A is separated from the suction cup 23 and dropped onto the bag position correcting device 12 disposed above the suction conveyor 2 (E). The packaging bag supply device 9 is configured to supply these packaging bags A one by one to the suction conveyor 2 by repeating these operations.

  The bag position correcting device 12 is for correcting the position (positioning) of the packaging bags A conveyed to the suction conveyor 2 one by one and dropping them on the suction conveyor 2. As shown in FIG. 7 or FIG. 8, the bag position correcting device 12 of this embodiment includes a front end guide 24, a shutter 13 that holds the packaging bag A and then drops onto the suction conveyor 2, and the conveyance direction of the suction conveyor 2. The first correction guide 14 that reciprocates along the width of the suction conveyor 2 and the second correction guide 15 that reciprocates along the width direction of the suction conveyor 2.

  The front guide 24 has a locking plate 24 a that locks the bottom of the packaging bag A, and has a pressing portion 24 b that moves up and down to press the packaging bag A from above, and is orthogonal to the conveyance direction of the suction conveyor 2. It is provided on the downstream side of the shutter 13 so as to extend in the direction of the shutter.

  The shutters 13 are provided along the conveying direction on both sides of the suction conveyor 2 in the width direction. The shutter 13 has a plurality of protruding pieces extending in a direction (width direction) orthogonal to the transport direction, and the shutter 13 on both sides along the ball screw is a direction (width) orthogonal to the transport direction of the suction conveyor 2. Direction). Then, when the shutters 13 on both sides approach in the direction (width direction) orthogonal to the conveying direction of the suction conveyor 2, the packaging bag A can be held on the upper surfaces of the plurality of protruding pieces, and the shutters 13 on both sides serve as the suction conveyor 2. The packaging bag A is configured to fall on the bag placement floor plate 20 attached to the conveyance belt 19 of the suction conveyor 2 by being separated in a direction (width direction) orthogonal to the conveyance direction.

  The first correction guide 14 is provided on the upstream side of the shutter 13 in the transport direction of the suction conveyor 2 and is configured to be capable of reciprocating along the transport direction of the suction conveyor 2. Then, the first correction guide 14 is configured to position the packaging bag A by pressing the upper end side portion of the packaging bag A by moving to the downstream side along the conveyance direction.

  The second correction guides 15 are respectively provided on both sides in the width direction above the shutter 13 and are configured to be able to reciprocate along the width direction of the suction conveyor 2. The second correction guide 15 has a plurality of protruding pieces extending downward, and these reciprocate along the width direction in a state where they enter the gaps between the plurality of protruding pieces of the shutter 13. By being configured to be movable, the packaging bag A placed above the shutter 13 is pressed so that the packaging bag A can be positioned in the width direction.

  Specifically, the second correction guides 15 on both sides approach in the direction (width direction) orthogonal to the transport direction of the suction conveyor 2, so that the packaging bag A placed above the shutter 13 is placed on both sides in the width direction. Can be positioned in the width direction of the packaging bag A, and the second correction guides 15 on both sides are separated from each other in the direction (width direction) orthogonal to the transport direction of the suction conveyor 2, thereby The packaging bag A is separated and can be placed on the upper surface of the shutter 13.

  As an operation of the bag position correction device 12, first, as shown in FIG. 7A, the first correction guide 14 is moved backward with the shutter 13 moved toward the inner side in the width direction. Then, the second correction guide 15 is separated in the width direction, the suction of the suction cup 23 is released, and the packaging bag A is dropped and placed on the upper surface of the shutter 13.

  Next, as shown in FIG. 7B, the first correction guide 14 is moved to the downstream side (conveying direction) to press the packaging bag A so that the packaging bag A is brought into contact with the locking plate 24a for packaging. While positioning the bag A, the second correction guide 15 is moved closer to the width direction to position the packaging bag A in the width direction.

  Further, as shown in FIG. 7C, the entire bag position correcting device 12 is lowered and brought closer to the suction conveyor 2. Thereafter, as shown in FIG. 8 (D), the shutters 13 are moved and separated toward the outside in the width direction, the packaging bag A is dropped onto the suction conveyor 2, and at the same time, the pressing portion 24b of the tip guide 24 is lowered. To hold the packaging bag A from above.

  Next, as shown in FIG. 8E, the entire bag position correcting device 12 is raised and separated from the suction conveyor 2. Thereafter, as shown in FIG. 8F, in the state where the shutter 13 is moved toward the inner side in the width direction and approached, the first correction guide 14 is moved backward to move the second correction guide 15 in the width direction. Further, the pressing portion 24b of the tip guide 24 is raised to return to the initial state shown in FIG.
