Terminal 400 Double DownStacker
The Fosber Terminal 400 Double DownStacker provides the most versatile. combination of corrugator stacking. The Terminal is designed to stack sheets at high speeds forming full height stacks, bundles or a combination of both. Modular design of the support structure allows complete layout flexibility and ease of installation. The electrical and pneumatic requirements for wiring, piping and cable ducts are integrated into the design of the support structure. The PVC belts all have integrated V-guides located under each side of the belt. The V-guides run in groves which prevent any lateral movement of the belt even during acceleration. Each level of the terminal is designed with three or more belts with individual PLC control.
The Terminal Stacker has three main sections:
The Braking Section - Is composed of a series of carbon fiber brushes, which apply adjustable pressure on the sheets. This slows down and shingles the sheets exiting the cut-off knife. The pressure and number of brushes activated are automatically controlled according to the type of production. Onboard manual controls are also included.
The Separation Section separates the stream of shingled sheets, moving to stack change or order change. Precise separation is accomplished via a fixed or moving clamp system (for higher line speeds), which separates the sheets cleanly even in case of severe warp or coated (slippery) sheets. At separation the lower interrupt bar raises while the upper lowers; thus, holding back the first sheet of the new stack (or order) The old stack (or order) is then gently accelerated away.
The Stacking Section - consists of a no-crush nip-roll, a motorized stacking platform and a motorized backstop with encoder control. The elevator deck is gently and linearly lowered via an electrical motor allowing sheet-by-sheet descent, keeping a constant angle of the sheet onto the stack.
The Terminal Stacker utilizes an intelligent machine control program. This assures excellent stack quality and optimized speed for all board types.
