The company’s piGRIP cups feature a plastic insert that prevents flexible packages from being sucked up into the suction cup of a vacuum-based automated system, as well as a flexible lip made of soft 50-Shore silicone that helps it to conform to the irregularities of a bag’s surface. These features help to prevent unattractive pucker marks and dropping of the packages, especially when working with thin bag materials such as plastic film.
A special fitting also allows more vacuum flow through the cup, enabling cups to be cycled faster.
“The idea of having more of the cup’s surface area on the bag surface along with the cup’s strong body allows the user to increase speeds on their production lines without the danger of missing bags or losing bags,” Mike Tuohey, Regional Marketing Manager – Americas for Piab, tells Packaging Digest via email. “More cup on the bag means a strong tight grip without risk of failure.”
A case study on Piab’s website details the experience of an Italian customer that was handling bags filled with coffee pods. Working cycles ranged from 20 to 40 picks per minute with standard suction cups, and heavier bags were sometimes dropped, resulting in production stoppages. When the customer switched to piGRIP suction cups, it was able to maximize speeds while eliminating dropping, thus increasing productivity.
