Hartfiel Partner’s With Machine Manufacturer to Achieve Faster Cycle Times With High Accuracy


Viking Engineering is an industry leading manufacturer of automated bedding, nailing, and pallet equipment. Hartfiel Automation has been a key supplier to Viking for many years.

The Scout is Viking’s most accurate, automated bedding machinery on the market today. The Scout staples box springs onto wood frames by utilizing four CNC heads on dual gantries. Utilizing the B&R controls platform, the advanced motion control and fast cycle times at the core of this machine make B&R an excellent fit. 


The Scout was designed with the lofty goal of high accuracy and low cycle times. The proposed solution was to use multiple guns operating in tandem to divide the work of stapling a box spring to increase throughput. The frame and box spring would be conveyed into place and then the stapling would begin. Once finished, the product would be conveyed out while the next comes infor a continuous cycle.

A significant challenge in this process would be to identify where the box spring is located relative to the frame. This is especially difficult because the springs are often manufactured with tolerances outside that of the width of a staple. Furthermore, the spring can move slightly throughout the process.


This solution was achieved by developing four independent, 3-axis CNC machines that use shared dual drive gantries. 

Each head can operate simultaneously to staple the rows of the box spring. Collision avoidance procedures were developed to allow operation in the same work zone. SICK laser distance scanners were mounted on each side of the staple guns. A custom algorithm was then developed to determine where wires are located from the distance data. These wire locations are passed dynamically to the CNC programs to adjust their planned positions on the fly. 

Hartfiel’s ATLAS team worked together with Viking engineers to utilize B&R’s highly customizable motion and control platform to solve these complex challenges.
