02 Frontal view of the additonal three-storey floating platform WAREHOUSING house within the existing infrastructure, including incorporation and optimization of the current processes. Essentially, two Logimats would be installed for storage and picking of small parts, and a container and carton conveying system would be built to link goods-in with the various picking stations over three levels (Image 01). First steps in warehouse automation SSI Schaefer started work shortly after the contract was signed in October 2014, while the warehouse continued to operate. The first step was to dismantle parts of the platform system so that the Logimats could be installed side by side in the specified position. The fitters then erected the two automatic storage systems, which extended to just under the warehouse roof as they can be built to any specified height. The Logimat principle can be compared with an oversized, automatic drawer cabinet with two stacks of trays. A lift running between the two stacks of trays removes the individual trays from their allocated position and transports them to the pick face where the warehouse staff can remove the goods to be picked at an ergonomic height. In front of the two Logimats, Niemann+Frey has a picking station with ten container storage locations and putto-light displays. Immediately behind them, the conveying section runs towards the three other manual picking stations. Another three-storey floating platform was added to the existing three-storey platform system by building over the existing goods-in area, which was redesigned with new work station systems (Image 02). Part of the new platform is used as a conveyor branch with a buffer section for the individual picking levels. Installation of the conveying system, including a roller conveyor with belt conveyors to supply the platform, greatly reduced the distances walked by pickers and they no longer need to change level by walking up the stairs with containers or goods. This has made picking at the upper levels much more efficient, with faster access to the articles stored at those levels. “Niemann+Frey had very specific concepts and ideas with regard to expansion of its warehouse, which we then developed together. In particular, the order picking process using the Logimat, combined with put-to-light assignment and still using manual guidance of the container to the four picking stations via the conveying system, based on lists and simple identification information was new to us in this form,” explains Felix Lütkebomk, SSI Schaefer project About SSI Schaefer SSI Schaefer is the world’s leading supplier of warehousing and logistics systems. The services offered range from elaborating designs to equipping warehouses with products from the company’s own production and implementing comprehensive logistics projects as the general contractor. The grouping of competencies under the umbrella brand name of SSI Schaefer forms the basis of developing storage systems geared to market requirements and of finding holistic solutions in the field of intralogistics for a variety of industries. f+h Intralogistics 2/2016

manager at the end of the implementation phase, which lasted approximately two-and-a-half months. For Niemann+Frey, on the other hand, the project was the first step towards automatic support for its internal storage, transport and picking processes. “We needed to create more space for our goods and the Logimat has enabled us to access significantly more articles from ground level using the goods-to-person principle, even when they are stored at higher levels. We have also increased our picking performance for the range of articles stored here because eliminating walking time and introducing parallel picking of ten orders at a time has made us much faster,” says Schild. Logimat – plenty of space within a very small area The Logimat storage lifts were installed in the existing platform system immediately behind the goods-in area and have space for 12,000 different articles. They start to retrieve the correct tray of goods as soon as the picker has linked the first order with the first container by scanning the barcode. Picking starts when all ten containers have been assigned to an order. The employee always operates the two Logimats alternately by confirming each pick on the pick-to-light module. The software from SSI Schaefer is linked to the ERP system by an interface and controls the sequence of articles to be picked so that, wherever possible, it always retrieves a tray which contains several of the articles needed for the orders that are currently being picked. For easier picking, the LogiTilt function tilts the tray and the correct compartment is indicated by a laser pointer and on the stand-up display. The put-to-light display above the containers tells the picker where to place the article that has just been removed from the Logimat. Some articles also need to be labelled or packed separately. The light turns green to indicate that the last article in the order has been picked and the container can then be pushed onto the conveying section and moved to the transfer location for goods-out. If the container has to go to other picking warehouse zones, the employee attaches a clip to the container as an identifying mark for colleagues at the individual stations. Summing up, Schild explains: “Orders now move through the warehouse faster as the conveying system takes the container to the right picking warehouse zone and it takes less time to reach goods-out. As a result, utilization of the individual areas is much more consistent.” Photographs: SSI Schaefer www.ssi-schaefer.com Click to read previous issues. Inspiration is just one click away.
