, The air discharge device 6 is activated by the signal, and the pressurized air is discharged from the upper part of the base toward the lower part of the lower oblique direction. Body 12
Is pressed against the regulating plate 14 on the line connecting
As a result, the rounded edge on the side of the hanging portion faces the operator side by the curling action when the hanging portion of the rectangular wrapping gets over the resistor 12, and the rectangular wrapping can be turned over.
When the rounded edge on the side of the hanging part is in a normal state, the body moves without being turned over.

On the other hand, during this time, the rotary circulating device 11 continues to move in the depth direction of the base, and the rectangular wrapping which has been turned upside down as described above has the right and left corners E, E of the upper side D. By being gripped by the holding devices 8, 8, the upper side D moves to the back side, and the hanging portion contacts the rotating device 16 provided above the regulating plate 14. After a lapse of a predetermined time, the rotation circulating device 11 starts operating and the rotating device 1
Due to the rotation of 6, the hanging portion of the rectangular wrapping gets over the rotating device 16 and is transferred into the suction chamber 15 provided on the back side of the regulating plate 14.

When the hanging portion of the rectangular wrapper is transferred to the suction chamber 15, the air suction device 17 is operated to pull the hanging portion downward, so that the left and right gripping devices 8, 8 hold the hanging portion. Tension is generated between the upper side D of the shaped wrapping and the left and right sides and the lower side edges of the rectangular wrapping hanging down in the vertical direction are straightened. During this time, the rotating and circulating device 11 continues to move in the depth direction of the base, and the holding device 18 waiting at the back side of the base holds the upper side D of the rectangular wrapping. The gripping devices 8, 8 release the gripping operation of the upper side corners E, E of the rectangular wrapping, and deliver the upper side D to the gripping device 18.

When the delivery is completed, the rectangular wrapping A is transferred to the next process by the transfer device 19 while the hanging portion is pulled into the suction chamber 15, while the rotary circulating device 11 grips the left and right sides. The devices 8, 8 move upward from the back side of the base and return to the original standby position in front of the working side. The right and left gripping devices 8, 8 are attached to the rotating circulating device 11 at appropriate positions in the traveling direction at appropriate intervals, and after the rectangular wrapping A is received by the gripping device 18, the transfer device 19 During the process of transferring to the next process side, if the other left and right gripping devices 8 and 8 stand by at a position where they can grip both upper corners of the next rectangular wrapping, the work can be performed continuously. .
At this time, in the rectangular wrapping to be processed next, both upper corners are exposed by the hanging type body different from the hanging type body that was initially hung, and each of the corners is placed in the predetermined position. The left and right gripping devices 8, 8 that are waiting are gripped.

By repeating the above-mentioned operations, the turning operation of the rectangular wrapping A can be successively performed.
