System for alignment of big bags and method therefore

A system for alignment of big bags prior to product filling, the system comprising:

• a frame defining a working space configured for receiving a big bag comprising:
• a top with an opening;
• a bottom;
• and
• sides extending from the top to the bottom, wherein the bag is configured for holding a volume in the range of 500 L to 3000 L and/or having a height when inflated from the bottom to the top in the range of 0.5 m to 2.5 m;
• a spout;
• and
• a holder configured for holding the big bag at the opening (18) of the big bag, such that the spout extends into the opening of the big bag, wherein the system is adapted for filling gas into the big bag through the opening to inflate the big bag when suspended by the holder;
• an alignment arrangement configured to rotate the big bag when inflated and comprising a drive configured to operate a rotation part in a working space;
• a counter hold;
• a displacement arrangement for displacing the alignment arrangement and/or the counter hold in the working space to bring the rotation part into contact with a first side of the big bag when inflated and the counter hold into contact with a second side of the big bag when inflated opposing the first side of the big bag when inflated;
• a sensor arrangement configured to detect a rotational orientation of the big bag when inflated in the working space and adapted to provide a sensor output based thereon;
• and
• a controller configured to receive the sensor output and control the drive to rotate the big bag when inflated based on the sensor output by the rotation part.
