Vertical accumulator is LM’s accumulation model for a considerable quantity of products with a very limited overall footprint. It is designed for high frequency lines, with extremely short loading and unloading cycles that adapt dynamically to the changes in speed of the line, going from the loading to the unloading phase and vice versa in just a few seconds. Vertical accumulator is suitable for storing products in small and medium sized rigid packaging, which are accumulated in groups on a large number of stacked shelves (based on the height) that lift as they are filled. The buffers are provided with the necessary product pace and grouping systems to optimise shelf filling. They maintain the production cycle of the machines upstream and drastically increase the efficiency of the lines.
