Abstract: A device for taking over, temporarily storing and passing on elongated, hollow-cylindrical product units, preferably tubes, sleeves or cans, which come from a production line, has a first supplying conveyor belt and a continuously delivering second conveyor belt. The first and the second conveyor belts are disposed horizontally lying one above the other in a transfer zone. An intermediate storage arrangement is designed as a high-rack storage arrangement or as a paternoster storage arrangement. At least one handling robot is also located in the region of the transfer zone between the conveyor belts and the intermediate storage arrangement. This handling robot is designed either (a) to take a number of product units from the first conveyor belt and to feed them to the second conveyor belt or the intermediate storage arrangement, or (b) to remove a number of product units from the intermediate storage arrangement and to feed them to the second conveyor belt.
