Abstract
A device for the optimized circulation of mandrels includes a presentation and/or cooling table for mandrel rods, a lubricating station for the mandrel rods, optionally an additional drying station for the lubricant applied to the mandrels, and associated roller conveyors. An additional secondary rod circulation of is arranged upstream of the standard rod circulation and includes two redundantly operating transfer tables connected to the presentation and/or cooling table by a third roller conveyor or the first roller conveyor for the discharge of no longer needed rods from the standard rod circulation. The third roller conveyor either forms the continuation of the first roller conveyor or is arranged parallel thereto with an offset. A fourth roller conveyor for accommodating mandrel rods or passing mandrel rods intermittently into the standard circulation via an intermediate buffer is arranged on the opposite side of the transfer tables parallel to the first roller conveyor.
