Solutions in Action: Triangle Package Machinery

OEM Solution: Triangle Package Machinery

More than ever, food manufacturers are looking for packaging solutions that offer versatility, improved production, and reliable sanitation and maintenance features.

Since 1923, family-owned and -operated Triangle Package Machinery Company has helped food manufacturers achieve their packaging objectives with industry-leading, custom solutions, including vertical form-fill-seal (VFFS) baggers, combination weighers, horizontal cartoners and depositing systems. Triangle's VFFS flexible baggers are built to run various package sizes and styles and can meet stringent 3A dairy and USDA sanitation standards. The machines are also available with continuous or intermittent motion, depending on the end user's speed requirements.

The Model XYS08PRC bagger is a high speed, compact bagging machine designed to package nuts, rice, powders, small fresh-cut produce, and confectionery products.

Model XYS08 has recently been redesigned to offer an improved frame design, updated controls and larger control enclosure, optional adjustable human machine interface (HMI), and a more streamlined film cage – plus increased corrosion protection and other sanitation features.

Additionally, Model XYS08 offers quick changeover of forming tubes, film rolls and sealing jaws, which allows users to run supported or unsupported film and multiple bag sizes at speeds up to 150 bags per minute.

Finally, the XYS08 now offers the flexibility to run traditional heat sealing or ultrasonic welding. With this new capability, Triangle baggers can now provide ultrasonic sealing on bag widths as small as 2.75 inches.

The Model XYM15C/11U bagger, a flexible, medium-frame, vertical form-fill-seal (VFFS) bagger, is also available with heat sealing or ultrasonic welding. This model is ideal for applications such as poultry and seafood, produce, individually quick frozen (IQF) products, pasta and cereal, as well as shredded cheese and confectionery.

To meet high sanitation requirements, manufacturers can choose the company's USDA/3A bagger options, which feature stainless steel finishes and components, continuous weldments and no sandwiched metals or crevices.

The USDA/3A versions include an option for Allen-Bradley® MP-Series™ stainless steel motors, which help enable full washdown capabilities in accordance with best practices for food safety. Two of the motors transport the packaging film down the forming tube, while two others close and seal the package.

Depending on the application, motion and control execution is managed using either the Allen-Bradley ControlLogix® or CompactLogix™ programmable automation controller (PAC).

Through an EtherNet/IP™ network, the controller is tightly synchronized with Allen-Bradley Kinetix® 5500 servo drives, which run Kinetix VPF food-grade servo motors. Alternately, integrated drive-motor functionality can be achieved using Kinetix 6000 servo drives, food-grade MP-Series servo motors and a SERCOS interface. Allen-Bradley PanelView™ Plus 6 graphic terminals provide easy access to critical machine information.

“We've been internally standardizing on Rockwell Automation control equipment for years and it's been a tremendous advantage for us,” said Steve Bergholt, director of sales engineering, Triangle Package Machinery Company. “From the design, to troubleshooting, to overall maintenance, the Integrated Architecture® system makes everything much easier because there is just one point of communication. All I have to do is look at my PAC to know what every part of my machine is doing.”

The company's Model XYT15 bagger is also controlled by Rockwell Automation equipment. With an optional zipper applicator, the continuous motion bagging machine can run a variety of bag styles including pillow, gusset, flat bottom, and even quad-seal or four-corner bags.

The four-corner bags off er improved sustainability and material savings for multiple industries including cereal, IQF products and poultry. To provide food producers with a fully integrated bagging and scale system, Triangle combines the bagger with its Model A918 combination weigher, the only combination weigher in the industry controlled by a PAC.

The system's unique continuous motion – critical to productivity – is managed by the ControlLogix PAC. Since the machine's speed is aligned with the amount of product entering the system, users can avoid the downtime that typically occurs with intermittent machines, which must be stopped to allow production to catch up.

Finally, for bag in box applications such as cereal, powder, grains and bakery products, Triangle off ers the Flex 1 horizontal cartoner. The machine is also suitable for IQF products or trays, such as home meal replacement (HMR) kits. This fl exible cartoner features a compact footprint and quick, tool-less changeover to run various carton sizes – and also off ers an optional width and depth changeover.

The machine's control system includes ControlLogix controllers, Kinetix 6000 servo drives, and Allen-Bradley PowerFlex® 525 AC drives. The Flex 1 cartoner can be paired with the Triangle combination weigher and VFFS bagger for a complete, integrated system.

“All of our equipment is customized with features and options tailored to the needs of our customers,” Bergholt said. “The dependable, integrated solutions from Rockwell Automation give us the agility we need to develop and deliver the best packaging solutions possible.”
