Rennco’s New NextGen Series of Vertical Bagging Machines Improves on Time and Reliability

Nov 03, 2016

HOMER, MI — Rennco, powered by ProMach, introduces at Pack Expo 2016, November 6-9 in Chicago, a new platform for the company’s extensive line of vertical bagging machines. The NextGen Series represents design breakthroughs for every major functional system on Rennco vertical bagging machines. A new machine built on the NextGen platform will demonstrate at Pack Expo counting and bagging cups at a rate of up to 60 bags per minute. (Rennco Pack Expo Booth # S-3836)

Machine Upgrades
At 60 bags per minute, NextGen series-based machines are 33 percent faster than last generation offerings. The company also moved beyond intermittent motion to a continuous motion servo and upgraded its PLC platform to achieve speed increases.

“After extensive customer research, we’ve identified that customers care about sealing quality and fast changeover,” says Jim Zurawski, General Manager at Rennco. To address this, the Rennco design team simplified the sealing bar design, lowered the number of parts, and reduced required adjustments in a complete revamp, which achieved a significant increase in changeover speed and sealing quality. The NextGen series sealing system will not only be offered on new machines, but also as a retrofit for existing machines. The new sealing system will have a standalone display at Pack Expo to showcase its advanced capabilities.

A larger and easier to use HMI will be packed with operational and maintenance information. The HMI identifies the exact machine settings for key mechanical adjustments and operators simply dial in those settings. NextGen series changeovers are accomplished in less than five minutes.

The rugged frame has been lowered, compared to previous models, to make the new series machines easier to operate and maintain. Drive mechanisms have been located toward the back of the machine for better access to film and the product zone. Loading the film closer to floor level minimizes lifting. The new servo trim windup system has been updated for greater reliability and control through the HMI.

NextGen series machines are manufactured in the US. Replacement parts are readily available, and technical support is a phone call away.
