Double E Introduces New “Solis” Accumulators to Ensure Constant Web Tension During Manual Splicing

Double E Company’s new “Solis” web material accumulators deliver stored web material when part of a production process must come to a stop while the rest of the line continues to run. They stand apart from other accumulators by offering closed loop tension control throughout the cycle and by allowing programmable storage amounts that can be changed on the fly.

Double E Company's "Solis" accumulators deliver stored web material when part of a production process must come to a stop while the rest of the line continues to run. Unlike other accumulators, Solis offers programmable material storage amounts, and closed-loop tension control to ensure consistent moving web tension during a manual splice. This ability not only increases efficiency by keeping the line running, but also contributes to end product quality in processes that require constant web movement, like coating or laminating. Nonwovens applications are particularly well-suited to benefit from an accumulator because web speeds are often relatively slow. Solis accumulators offer advanced technology and user-friendly features to execute storage and delivery easily, with perfect web tension.

One of the most important characteristics of the Solis is its ability to maintain proper and consistent web tension at all times. The Solis accumulator operates as its own tension zone by means of a servo driven infeed roller and an outfeed pneumatic dancer roller. This unique system gives operators the necessary control to set and change material amounts on the fly without ever affecting web tension. A clear, intuitive touch-screen controller makes that operation, and many others, simple and fast. The cycle can be started locally or remotely, and alarms can be set easily to alert operators when stored material reaches user-defined levels.

Other features help to save money, further improve product quality, and ensure safety. Sleep mode, for example, puts the machine to rest between cycles to reduce energy consumption. Design parameters allow easy integration of web guiding or inspection lamps to further assist in end product quality. Interlocked guards and strategically placed emergency stops ensure operator safety.

Double E's Solis accumulators are available in three sizes. The "Solis 50" stores up to 50 feet of material up to 30 inches in width, with tension up to 3 PLI. Likewise, the "Solis 100" stores up to 100 feet of material up to 60 inches in width, with tension up to 2 PLI. Finally, the "Solis 200" stores up to 200 feet of material up to 90 inches in width, with tension up to 1.5 PLI. These accumulators can be integrated in existing production lines, and can be complemented by Double E unwind stands, rewind stands, and other web accessories including core shafts and rollers.

ST Robotics - R17HS-6, the 6-axis version of the high speed R17 variant

The 6-axis version of the R17HS high speed variant of the R17 robot is now available. As is our policy the 6th axis is an optional bolt-on module. At the same time we have made it even faster and new software eliminates shake and greatly improves repeatability as this video shows. Please see https://www.youtube.com/watch?v=3wG0MeiJ-yE. The video would seem to imply a repeatability of 0.01mm but we are sticking with 0.2mm in the spec. The motor specialist was able to tune the motors from the other side of the pond. My first reaction when we put power on and entered the first commands was to jump back in amazement (and maybe an expletive). Tip speed is now 3m/s; that's 3 times as fast as its nearest competitor yet costs half the price. I love it when a plan comes together.
