Customer quality requirements are constantly increasing. The manufacture of packaging products for the world market has become a rewarding but also very competitive business. It is therefore key to deliver only perfect quality. At the same time machine speeds have also increased which means that now more tubes have to be checked within a limited time frame. Manual quality inspection is getting difficult and expensive.
A Tube Inspection System has a significant impact on quality levels. Formerly hidden defects, e.g. those located under the cap or Top Seal, can be made visible to the operators and production problems causing imperfect quality can become immediately apparent. The Tube Inspection System allows parameters and tolerance settings to be stored for each type of product; with this, the output quality is being equalized. The system is integrated into the existing machine control system which allows to identify, mark and eject any defective tubes before they enter the following machine.
|Head||Shoulder and orifice from top|
|Side||Tube thread area
(3 cameras from side)
|Body orientation||Angular position of tube body|
|Top Seal||Position and integrity of Top Seal|
|Cap-to-Tube orientation||Angular position of cap and tube body|
|Inside||Inside shoulder and orifice
(on outfeed conveyor)
The inspection system is capable of proofing countless inspection features on a tube. However, the most common settings are kept simplified:
