Bag transport and tilt-correction device

A bag transport and tilt-correction device comprising:

• a gripping member which is openable and closable and, when closed, grips a top edge part of a bag supplied in a substantially vertical orientation and suspends the bag,
• an opening and closing means for opening and closing the gripping member,
• a reciprocal movement means for reciprocating the gripping member between a bag receiving position and a bag hand-over position, and
• a reciprocal swing means for swinging the gripping member within a vertical plane along a width direction of the gripped bag during the reciprocating motion of the gripping member;
• wherein the gripping member is:
• closed at the bag receiving position to grip the top edge part of the bag,
• swung within the vertical plane during the process of being moved to the bag hand-over position to correct tilt of the bag, and
• opened at the bag band-over position to release the bag;
• and
• wherein
• the reciprocal movement means is provided with a reciprocal moving body that reciprocates in a horizontal direction, and the gripping member is supported on the reciprocal moving body so as to swing within the vertical plane,
• the reciprocal swing means is comprised of
• a swing lever connected to a swing shaft of the gripping member,
• a cam rail installed along a direction of the movement of the reciprocal moving body on a fixed frame, a height of the cam rail being adjustable along the length direction of the cam rail,
• a driven body which is moved on the cam rail by the reciprocating motion of the reciprocal moving body, and
• a linking mechanism that links the swing lever and the driven body;
• and
• wherein during the reciprocating motion of the reciprocal moving body,
• the swing lever swings within the vertical plane via the driven body and the linking mechanism, and
• the gripping member swings within the vertical plane.
