First-In, Last-Out Vertical Accumulator

Rolco's FILO (First-In, Last-Out) Vertical Accumulator allows product to pass through the unit in normal operation. When a downstream malfunction occurs, the accumulator will back up one row of products on the transport conveyor. The process will continue until the accumulator is full or downstream production resumes. At such time, the accumulator will reverse and deposit rows of product back onto the transportation conveyor.

Features of the First-In, Last-Out Accumulator

• Production line dowtime is significantly reduced, thereby increasing production efficiencies and operating profits.
• Vertical product accumulation maximizes the effective use of manufacturing space.
• Product orientation is maintained.
• Simple interface with new or existing machines.
• Alleviates the need to halt production or stack off products.
• Minimizes product damage.
• Allows two or more machines which operate at different efficiencies to be connected together.
