Kunert Wellpappe is planning a new automated high-bay warehouse to create space for production expansions. Hörmann Logistik has been awarded the contract to realise the warehouse with connecting conveyor technology.
The Kunert corrugated board Bad Neustadt GmbH is part of the family-run Kunert Group, which 300,000 tonnes of cores, edge protectors and packaging made of corrugated board every year and over 225,000 tonnes of core board produced.
The new warehouse is also intended to Changed customer requirements to smaller order quantities, Shorter delivery cycles and Efficient inventory management to fulfil the requirements. A special feature of the four-aisle channel storage system is the Multi-deep transverse storage of a wide variety of finished goods formats on different pallet types and on several sub-pallets.
Pallet cycle connects different areas
The packaging units are transported from production on a distribution trolley for transfer to the new conveyor system. Care is already taken during production to ensure that, wherever possible Two identical packing units in a row transported, which then in the high-bay warehouse area as a pair can be conveyed, stored and retrieved. This Increases throughput capacity of the warehouse. A packing unit can have up to six sub-pallets. About a contour control the packing units are centred and checked for length, width, height, pallet width, pallet length and weight. The conveyor system then takes the packaging units to the pre-zone of the high-bay warehouse, where a pallet circuit with special chain conveyors and roller lifting tables The system combines the areas of production, high-bay warehouse and dispatch provision.
Battery-powered sewer vehicles
For storage in the new channel storage system, the packing units are stored at the storage point. with the help of a light grid precisely positioned. The Two-mast storage and retrieval machines (RBG) are equipped with chain conveyors and channel vehicles. In two aisles of the warehouse, the SRMs work with one channel vehicle each, in the other two aisles with two channel vehicles each to handle the transport of large pallets. The Sewerage vehicles are battery-powered and are loaded on the stacker crane during operation. The storage and retrieval machine picks up the packing unit crosswise and stores them several times deep in the storage channels with the help of the sewer vehicles in.
The Special challenge in the detailed planning and realisation of the new channel storage facility at Kunert Wellpappe lies in the very different formats and the large-format packaging units with several sub-pallets. In addition to transporting these very different packaging units on a special conveyor system, an ingenious compartment detail was required to enable the Large compartments can be used very flexibly and optimised for volume. Also unusual is the Overall height of the high-bay warehouse of approx. 42 m. This height results from the limited space available on the factory premises and the need to accommodate the maximum number of pallet spaces on the available area.
