Haver Filling Systems Inc. has added fully automated bag palletizing machines manufactured by Newtec Bag Palletizing to its line of bulk material packaging Haver-400
equipment.

The low- and high-level Haver palletizers precisely stack bags that are made of various materials and filled with a wide range of dry bulk products to form compact, stable bag stacks. They are used primarily for handling bags in the building materials and chemical industries.

Haver Filling Systems’ parent company, Oelde, Germany-based Haver Group, acquired Newtec Bag Palletizing from the Newtec International Group S.A. in 2012, and Haver is now offering the palletizing systems.

Haver Filling Systems President Claudio Caobianco said the addition of machines manufactured by Newtec Bag Palletizing is a natural extension for the company, one that makes the company a true full-liner. “We are now able to deliver complete storage, packing and stacking solutions for bulk materials,” said Caobianco. “Haver customers can get all their high- quality packaging equipment from a single supplier, and all of their machines can work together in one comprehensive, efficient and fully optimized system.”

There are nine series of Haver palletizers in all; handling bags that weigh 10 to 110 lb. and have capacities ranging from 100 to 6,000 bags per hour, depending on the material, type of bag and automated options. The equipment efficiently handles various sizes of paper, polyethylene and polypropylene valve and open-mouth bags, as well as form fill seal bags.

An HMI (Human Machine Interface) on each machine provides for intuitive operation. It enables the operator to undertake a product change with just a few settings, or to switch over to maintenance mode. In addition, Haver specialists are able to provide remote maintenance and continuous support through a VPN connection, which reduces maintenance time and leads to cost savings.

Depending on customer needs, the product flow after packaging goes through several efficiency- and quality-enhancing stations, such as check-weighers, gluing systems, pallet presses, bag flatteners and bag rejecters.

Bag rejection separates overweight and underweight bags to ensure the final product is of the highest quality. In addition, operators can apply fully automatic slip-sheets to the pallets or to each layer to provide additional stability. In a subsequent process, they can wrap and shrink weather-protective and stability-enhancing films around the pallets.

At that point, the customer can load the bags or send them to a palletizing system, which produces a package unit suitable for transport and storage. The bags go through a pressing belt that removes excess air, and a turning clamp places them in the desired position to form an optimum layer pattern. Air-removal rollers press out the excess air and compact the product for perfect palletizing.

Haver’s palletizing equipment also includes polyarticulated robots and bag palletizers with layer deposit or robotic grippers. In addition, the line encompasses final-check and pallet-wrapping systems.
