A new vertical form, fill and seal machine is designed to package high density snacks into smaller bags at high speed, its manufacturer claims. TNA said its Robag 3 fx 180 Rotary Triple Jaw (RTJ) vertical form, fill and seal (VFFS) bagger can operate at 300 bags per minute. The Robag features a swing-out former mechanism for easy unloading and rapid tool-less changeover that can be completed within one minute, the company claims. Integrated in the mechanism is an optional auto-connect system for air blasts and nitrogen flushing, which removes the problem manual handling pipes and hoses. The Robag includes a single action film threading a simple dancer mechanism for film tensioning and feeding, and a splice assist unit, which reduces film changeovers, claims the manufacturer. The TNA Intelli-sys links all system components to the Robag touch-screen using software running under the Linux Operating System. All components can be controlled using the Intelli-sys touch-screen interface, which can be operated with minimal training, claims the manufacturer. The drive system is operated using software, which controls the auto positioning and auto opening and the self-adjusting vertical seal units. Wash downs and maintenance are made simpler because belt changes require the pull of a single lever, claims TNA. Once a bag is formed, the Robag collections information from all pieces of equipment that can potentially be fed to a computer to provide performance reports to any PC, in real time.
