MATERIAL FLOW 02 Source pallets with bulk goods or small parts that cannot be automatically unloaded are transferred to six manual repacking stations by the transfer carriage 03 SAP EWM calculates the assignment of the locations needing supply to the tours, plans the trains, trailers and storage locations accordingly and organizes and controls the entire processes ning tool was designed to meet the project’s specific requirements of the route logistics and Brose’s special requirements in collaboration with the Technische Universität München. This was directly implemented within SAP EWM by SSI Schaefer as part of the project. The planning tool enables the scheduling of the tugger trains according to a timetable that depends on shifts, breaks, routes and much more (Image 03). The tugger trains are synchronized. For each travel cycle, there are 45 minutes per station for retrieval, staging and loading processes. Retrievals are issued via the SAP system. If stock is running low, the staff members at the production stations scan the overflow totes with the required material. Based on this, SAP EWM generates a request in the miniload and initiates the corresponding retrieval. At the same time, the integrated timetable generator in the SAP system calculates the duration of the tugger train travel, taking into account the route. It then generates the ideal storage location to ensure dynamically optimized occupancy of the individual tugger trains. “We had to develop new routines and algorithms for the SAP EWM which could calculate and control the ideal time window for tote retrieval, sequenced staging of the correct Kanban route as well as the automatic loading of the tugger trains,” explains Jürgen Hergenröther, Project Manager IT/SAP at SSI Schaefer. “All this took place without influencing the standard of the system, to ensure that it would be upgrade compatible in the future.” The miniload totes are disbursed via a conveying section to the four tugger train stations according to the ideal sequence calculated by SAP EWM. The trips are based around the production areas; the unloading points are stored in SAP EWM. Each of the four stations consists of a racking system with four rack levels and a total of 32 tote channels. At the appropriate time for loading, a tugger train with four trailers enters the respective station. The trailers are equipped with a rack system. This is the same as the rack system in the station; it has two tote storage locations with rollers on four levels, one above the other, and provides a slight downward gradient – a total of eight totes per trailer, 32 per tugger train. If a tugger train has achieved the loading position, the totes are released. The locking roller lowers and the totes roll out onto the trailer storage locations. “SAP EWM calculates the assignment of the locations needing supply to the tours, plans the trains, trailers and storage locations accordingly and organizes and controls the entire process chain for the timely loading and supply of the relevant locations,” summarizes Hergenröther. Similar calculations underlie the staging of full pallets for production to the carrier stations that take complete loads.

Product News Liebherr supplies harbour cranes to Haiti In 2014 alone, customers based in 35 countries across the globe opted for Liebherr mobile harbour cranes (LHM). Recently, three new countries, for example Haiti, have joined the reference list. In June 2015, Port Lafito, Haiti received its first mobile harbour cranes. The port opted for two LHM 420s. With hoisting and lowering speeds of up to 120 metres per minute, each crane provides a capacity of more than 30 boxes per hour. To ensure efficient utilization, both cranes are equipped with Liebherr’s fleet management system LiDAT. The system allows for crane performance monitoring and key statistics analysis in order to ensure optimum turnover. Small moving mass − high performance Reliable partner for value-added warehouse automation The neo steel sequencer from MFI AG is used to supply goods receipt and order picking positions. The various lifting devices can be adapted and, for example, implemented as the manufacturer’s combi telescope for double-deep storage or removal of boxes or baskets with a maximum individual weight of 50 kg (payload 2 × 50 kg). To meet the requirements of one of its operators, the manufacturer developed a telescopic conveyor belt that can be used to store and retrieve containers from a shelving unit and that can handle boxes of different dimensions to transfer them to continuous conveyor belts, for example. The neo steel sequencer is designed to perform approx. 140 cycles per hour. Additional characteristics of the sequencer include the low approach dimensions and low moving mass (total payload incl. lifting device is approx. 300 kg). Thanks to its stainless steel design, the device can also be used in the food sector. Vanderlande is a major player in the warehouse automation market and specialises in solutions for food retail, fashion, parts and components and e-commerce. It cooperates closely with its customers to optimise their supply chain and enhance the efficiency of the processes in their distribution centres. The company is a one-stop shop for innovative systems, intelligent software and life-cycle services. This integrated approach results in an optimum performance throughout the system‘s lifetime. > Visit us at Cemat Russia from 22-25 september MOVING YOUR BUSINESS FORWARD
