US 2026/0079117 A1 · APPARATUS AND METHOD FOR INSPECTING FLEXIBLE BAGS

Abstract

An apparatus for inspecting flexible bags containing a liquid or viscous product including: a line for advancing the bags; a first device for gripping a first bag, the first bag forming part of the bags; a first device for lifting a part of the first gripping device; the first lifting device allowing inclination of the first gripping device to be changed with respect to a horizontal plane; a first rotatable device that rotates the first gripping device around a first rotation axis that is transverse to the line; a detection device for detecting defects of the bags and/or their contents; the detection device including a device for visual inspection of the first bag and/or its contents; a device for rejecting the bags according to information coming from the detecting device. The apparatus is a linear machine, not a carousel rotatable around its own rotation axis.

Dependent claims

An apparatus for inspecting flexible bags containing a liquid or viscous product comprising:

a line for advancing the bags;
first means for gripping a first bag, said first bag forming part of said bags;
first means for lifting at least one part of the first gripping means;
said first lifting means allowing the inclination of the first gripping means to be changed with respect to a fictitious horizontal plane;
first rotatable means that places in rotation the first gripping means on themselves with respect to a first rotation axis, preferably said first rotation axis being transverse to the line for advancing the first bag along said apparatus;
means for detecting defects of the bags and/or their contents;
said means for detecting defects comprising first means for visual inspection of the first bag and/or its contents;
means for rejecting the bags as a function of information coming from the means for detecting defects;
characterised in that it is a linear machine, not a carousel rotatable around its own rotation axis.

A method for inspecting flexible bags containing a liquid or a viscous product, said method comprising the steps of:

gripping a first bag placed along an advancement line by means of first gripping means;
said first bag forming part of said flexible bags;
lifting at least one part of the first bag gripped by the first gripping means, changing the inclination of the first bag with respect to a fictitious horizontal plane and positioning a first end of the first bag higher up than a second end of the first bag;
placing in rotation the first bag on itself around a first rotation axis, preferably transverse to the line for advancing the bags;
the step of placing in rotation the first bag occurring during and/or after the step of lifting the first bag;
seeking defects in the first bag placed along the advancement line, said step of seeking the defects comprising in turn the step of performing an inspection by means of first visual inspection means;
advancing the bags along the advancement line;
rejecting the bags along the advancement line as a function of information coming from the step of seeking defects in the first bag;
characterised in that the step of advancing the bags along the advancement line comprises the step of advancing the bags along a linear trajectory and not on a carousel rotatable around a rotation axis.
