Introducing LRP-30, the new leak detection machine for monobloc aerosol cans integrating BONFIG testing technology
After the development of the LRP-20, a leak testing machine for aluminum tubes, the collaboration between Sprimag, a world leader in industrial painting equipment, and Bonfiglioli Engineering S.r.l., the Italian-based branch of Packaging Test and Inspection Specialist TASITEST, has led to another excellent result: the LRP-30, a leak testing machine for monobloc aerosol cans that can be integrated into any line system concept thanks to the line-oriented transfer in and out of the machine.
At first glance, the LRP-30 appears to be very similar to the necking machine normally located upstream of the testing process, but, as opposed to machines used to test welded steel cans, the test plate of the LRP-30, which is equipped with 30 testing heads, is supported above a large, horizontal shaft by a two bearing support of the shaft ends. When the system is in operation, the cans are transferred from the outfeed conveyor system of the necking machine to the infeed conveyor system, which has been deliberately kept short and compact. A vacuum transfer starwheel picks up the cans and transfers them directly to one of the 30 testing heads in order to detect holes up to a diameter of 0.04 mm with a high level of reliability. The number of testing heads results in significantly longer testing times and therefore much more precise test results compared to the machine concepts previously used for monobloc aluminum cans. After testing, the cans are transferred directly to the outfeed conveyor system of the testing machine and then on to the downstream packing machine, a palletizer or a robotic packaging solution.
The compact overall design, the optimized width of the machine and the line-oriented transfer in and out of the machine make the LRP-30 able to be integrated into any line system concept.
In addition to optimized floor space requirements, the LRP-30 provides an easy machine handling and a quick size part changing. The entire machine, together with the infeed and outfeed conveyor systems, is driven by a single servo drive, thus avoiding unnecessary complexity and susceptibility to failure.
Other benefits from this sophisticated machine concept are: the possibility to manage the can length adjustment for other can sizes via a single user command on the HMI; the identical system accessibility of the machine corresponding to the upstream necking machine and the downstream packaging machine so that, at the end of the production process, all three machines can be optimally operated by just one person; and the presence of a high-quality, industrial designed machine cabin based on the design of tool manufacturing machines.
