MINITUB
inspection machine for plastic tubes.

Minitub guarantees a powerful combination of print quality and waste reduction. Objectivity and accuracy of the control improves your print quality and it ensures a production without printing defects.

Minitub ensures reliable defect detection with a full combination of printing process and printed artworks.

Minitub is easy to use: the setup of a new job can be done in less than 5 minute. The benefit results in cost reduction and improved process efficiency that drives up profits and company reputation. MINITUB is equipped with SPECTRO-L Vision System that ensures 100% print inspection and highly easy to use interface.

Minitub can be used as an independent stand alone module or can be integrated directly integrated into the production line, placing the machine itself after the printing machine or the after the capping machine.

The machines is composed by 5 axis: loading conveyor, loading slit, index table, inspection mandrel, unloading conveyor.

The tubes are forwarded lying on the inlet conveyor with their main axis transversal to the direction of the belt. On the conveyor an air flow aligns the tubes in order to achieve a proper loading in the machines.

The conveyor carries the tube to the loading station of the machine, where the vacuum keeps the tubes stable in position.

At each cycle, a linear slid push one tube onto one of the four mandrels of the central index table that moves of 90 degrees for each machine cycle.

All the mandrel are manufactured with a central duct that allows air flow in both directions: towards outside for the ejection of the tubes, towards inside to create vacuum and avoid slipping of the tubes during the image acquisition and movements during the rotation of the index table.

At each cycle, a linear slid push one tube onto one of the four mandrels of the central index table that moves of 90 degrees for each machine cycle.

Each tube stays on the index table for 4 stations:

1^st cycle – Loading

The tube is loaded onto the mandrel.

2^nd cycle – Inspection

The tube is spun around its axis. The vision system acquires the image and performs the control of the printed artwork. A vacuum on the mandrel avoid the sliding of the article on the mandrel.

3^rd cycle – Rejection

Thanks to air blow from the mandrel, the bad tubes are rejected into a flexible tube that bring the bad article to a box.

4^th cycle – Unloading

Thanks to air blow from the mandrel the article is unloaded on the output conveyor belt. The blow on the conveyor is controlled by the loading linear slid during its back movement.

The user interacts with the machine with a 10’’ touchscreen panel with a friendly and easy to use interface which provides quick access to all the features of the machine.

Tubes range - Cylindrical tubes

Max. length (included closure)	225 mm
Min. diameter:	19 mm
Max. diameter:	60 mm

The machine is provided with an easy to install bypass tool that allows the tubes to pass through, keeping the overall machine on its position on the production line.
