MULTIPLUS - print inspection machine for plastic bottles and mascaras.

NEW CONCEPT OF PRINT INSPECTION
Multiplus is the 100% universal quality control module for plastic bottles. The system can be used as a stand alone off-line inspection machine or it can be installed at the end of the printing line.

QUALITY IS EASY
Multiplus ensures reliable defect detection with a full combination of materials, printing process, artworks and bottle shapes. Spectro is easy to use: the setup of a new job can be done in less than one minute.

BENEFITS
Multiplus 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. On line integration allows waste reduction and printing process optimization. Spectro is able to prevent widespread failure and avert large quantities of waste. The benefit results in cost reduction and improved process efficiency that drives up profits and company reputation.

MULTICAP- inspection machine for plastic and metal clousures

MULTICAP is the inspection machine for the control of aluminium and plastic closures.

The standard configuration includes three acquisition units: one for the inspection of the Border and the Liner, one for the inspection of the Top-printing (public side) and one special unit with six cameras for the inspection of the external sidewall.

 

Mechanical transportation
Depending on the inspection requirements we have different solution for the mechanical transportation system. In the most common case clousures are oriented with opening upward facing.
Border and Liner/Pourer inspection, which requires top views of the closure, can be performed either on a conveyor belt (with caps moving properly lined and spaced) or on a star-wheel. The solution on a star-wheel is preferred, because of the best precision and stability in the caps holding, required especially for the inspection of the border that uses a wide-angle lens.

Ejection is managed by a supervision unit (PLC), using an encoder installed on the star-wheel axis. In this case, it is possible to reject the defective closures anywhere, setting the proper number of encoder pulses respect to the sync signal (step signal of the star-wheel).

For all the inspections, the cap must be hold steadily in the pockets during the movement, avoiding oscillations.

Top-printing inspection
Top-Printing inspection requires a star-wheel transportation, where a bottom view is possible through a hole in the main plate while the cap is held in the star’s pocket by a rubber belt or slips on a special glass. This inspection cannot be performed on a belt because in this case the Top-Printing surface is not visible, being hidden by the belt.
Star-wheel and of the other mechanical parts (holding edges…) in the inspection area are “opaque black”, to avoid light reflections that can affect the quality of the images.

Border Inspection
For the Border inspection, the border must protrude some mm (min. 5 mm) from the top surface of the star-wheel and of the holding edges.

Sidewall inspection
The inspection of the sidewall is performed with a six-colour cameras unit. The cameras, placed a 60° each other, observe all the lateral surface of the cap. The lighting system is a high intensity LEDs ring-light, designed to illuminate with high uniformity the external lateral surface of the closures. An additional light beam in the inside allows inspecting proper making of the closure, as for example the cutting.
After the acquisition of the images through the six views, the software reconstructs the complete horizontal development of the external lateral surface of the cap, aligning the edges of the six acquired images. For the mosaic only the central part of each 60° image is used, in order to limit the reduction of information in the part of images more distant from the optical axis. In any case, before joining and aligning the six images, a geometrical calibration is applied to each to correct the optical distortion.
Below the geometry of the sidewall standard unit, together with the six acquired images and the one resulting from the merging.

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.

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.

Each tube stays on the index table for 4 stations:

1st cycle – Loading

The tube is loaded onto the mandrel.

2nd 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.

3rd 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.

4th 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.
