できる。[Both sides of the side end are suction-supported, the suction plate I2 and the holding suction piece I3 are released from suction, and the product is sent to the opening station 20. At the opening station 20, the supporting suction piece 4a. The ventilation arms 3a and 3b are moved in the opposite direction of the arrow C while the suction arms 4b are sucking both sides of the bag body 6, and the support suction pieces 4a and 4b are separated to open the bag body 6. At this time, the straining piece 22 pushed out by the actuator 2I squeezes both ends of the opening edge of the bag body 6 inward to assist in opening. (Prior Art) However, in the conventional bag supply station 10 of such an automatic bag filling device, the cut bag body 6 is suctioned and held by the suction plate 12 and the holding suction piece 13, as shown in FIG. The support adsorption piece 4a of the bag body support device 5 is in an upright state.
, 4b, it is clamped and supported by the support and suction pieces 42L and 4b while remaining upright, and sent to the next opening station 20. Therefore, the suction surface +2a of the suction plate I2 and the suction surfaces of the supporting suction pieces 4a and 4b are made to coincide with each other on the same plane.
A suction plate 12 is placed on the top of the support suction piece 4b in the same plane as the suction surface.
A gripper 9 is provided facing the end surface 12a of the suction plate, so that the moving position of the support suction piece 4b is aligned with the end surface 12a of the suction plate. (Problems to be Solved by the Invention) However, synthetic resin films such as polyethylene have strong adhesion at the overlapped portions, so even if you try to open the bag by adsorbing both sides of the bag, the adhesion force will be too strong. The bag is larger, and the bag body separates from the support suction piece, making it easy to open the bag incorrectly. Although it was attempted to squeeze both ends of the opening edge of the bag body 6 from the outside to the inside with the straining piece 22 provided at the opening station 20, a sufficient effect could not be obtained due to slipping on the bag surface. (Means for Solving the Problems) In view of these points, the present invention provides support adsorption pieces 4a, 4.
Before opening the bag 6 by separating the bag 6
While keeping one side of the opening edge suctioned and held by the suction plate 12, by bending the lower part of the suction holding part of the bag toward the suctioned side, the other side that is not suctioned by the suction plate 12 is separated; Even if the bag body 6 is separated from the suction plate 12 and bent back to move to the next station, an air layer is formed at the opening edge. (Example) This will be described with reference to an example shown in FIGS. 1 to 3. When the suction plate 12 provided on the bag supply device 11 rotates toward the rotary table 2 side (position B in FIG. 5), it attaches not only to the support suction piece 4a of the bag support device 5 but also to the support suction piece 4b. The suction support surface 4C of the suction plate 4b is deviated inward from the suction surface 12a of the suction plate 2 when the support suction piece 4b is in the suction state. Therefore, the cut bag 6 is held and rotated by the suction plate 12 and the holding suction piece 13, and as shown in FIGS. After being inserted into the gap, when the supporting suction pieces 4a and 4b move in the direction of arrow C in FIG.
The lower part is the suction surface 1 of the suction plate 12.
2a, and is bent at the upper end of the support/adsorption piece 4b as shown in FIG. However, since one side of the opening edge is suctioned and held by the suction plate 12, the bottom end of the suction plate is forcibly bent close to a right angle.
Since the other side is not suctioned, the suction plate 1 is attached due to its elasticity.
Separate from 2 and open G between it and one side that is still adsorbed.
occurs. For this reason, after releasing the adsorption of the suction plate [2], an air layer is formed at the edge of the opening, weakening the adhesion strength, and the adhesion strength is weakened.
The opening is ensured by separating the support adsorption pieces 4a and 4b at 0. (Effects of the Invention) As described above, the present invention allows, before opening the bag, to bend the lower part of the opening edge of the bag toward the suctioned side while keeping one side of the opening edge of the bag held by suction. Because of this bending, the other side of the opening edge opens elastically, and even if the bag is folded back, an air layer is created between both sides of the opening edge of the bag, making it easier to separate. This completely prevents the occurrence of open errors, eliminates any hindrance to the next process, especially the work at the filling station, eliminates wastage of packaged items due to filling errors, and improves productivity. The effect of this can be obtained. In the above embodiment, the bag body 6 is folded by the bag body supporting device 5 at the end of the suction plate 12 at the bag supply station.
The bag body supporting device 5 is placed on top of the support suction pieces 4a and 4b with a slight gap, and the suction support surface 4c of the bag support device 5 is deviated to the inside of the suction plate, so that the bending is performed by the movement of the support suction pieces. Alternatively, a separate folding station may be provided, or the bag may be folded by moving a suction plate that has suctioned one side of the edge of the bag.
