Accumulator for paper rolls or other elongated products and related method

摘要

The accumulator includes at least one pair of chains substantially parallel to each other to which cradles are connected for receiving products to be stored, the cradles being mutually spaced along the pair of chains. Each cradle is connected to the pair of chains through constraining members. On each chain at least one intermediate constraining member is arranged between two adjacent cradles connected to the chains.

主权项

1. An accumulator for elongated products, comprising:
at least one pair of chains substantially parallel to each other, to which cradles are pivotally connected for receiving products to be stored, the cradles being mutually spaced along said pair of chains, wherein each cradle is connected to said pair of chains by constraining members; a product inlet; a product outlet; a positioning system for positioning the cradles along said chains;wherein said chains are driven around wheels with movable axes supported by a movable support and wheels with fixed axes, said wheels subdividing the two chains into storing branches in which the products are stored and empty branches, a lifting and lowering movement of said movable support modifying length of the storing branches and the empty branches to modify quantity of products storable in the accumulator; and wherein on each chain is arranged at least one constraining member intermediate between two consecutive cradles connected to said chains.
