Warehouse Management Product news
After layer-by-layer
depalletisation, trade units are pushed onto the trays by a pusher. The number of trade units per tray is determined by volume calculation.
where, and in what position, he should place the trade unit on the store pallet or the roll container. This considerably improves picking effectiveness and prevents all subsequent re-sorting of the trade units caused by sub- optimum grouping on the pallet. The operator is provided with an on-screen image of the article, its position on the load carrier, and the volume or quantity required. Parallel order picking onto two load carriers (eg. roll containers) simultaneously is possible.
Two pick shuttles can normally be integrated per picking aisle. Both shuttles are linked to the aisle ends by the conveyor system, so that operators can work independently of each other. The computer calculates the sequence of the picking items to minimise travel distance. After order picking is completed, the order load carrier is placed on a conveyor line and transported first to an automated wrapping station and then to the Goods Issue area. All customer orders are consolidated for tour- optimised delivery. The pick shuttle itself takes up a new, empty load carrier.
Pick shuttle with TÜV-certified ergonomics
The highly ergonomic nature of the ETP systems is achieved by the pick shuttle especially designed for this solution. The shuttle’s ergonomic qualities have been certified by German
technical inspection association, the TÜV. The shuttles are made by Witron subsidiary FAS. The picking cabin and the order load carrier have independent height positioning. For every item
always carried out in the optimum ergonomic posture – no lifting, no carrying, no bending. Every cabin is equipped with lighting, a display system and personal safety equipment.
Witron reports that the semi-automatic ETP offers significant benefits compared with conventional storage solutions in terms of ergonomics, reduced costs, increased picking speed and packing density.
Guided by the display and a light signal, the operator can always position the trade unit in the optimum place on the order pallet. Time- consuming rearrangement of the trade units, which can happen with conventional order picking, is no longer necessary. The result is tightly packed load carriers tailored to the layout of the store in question.

removed, the picking cabin is placed automatically in front of the trade unit’s picking station by computerised controls in such a way that the operator is always positioned in relation to the trade unit in an ergonomically ideal way. At the same time, the order pallet or roll container is also positioned automatically, depending on the filling level of the load carrier, in such a way that the operator can only place the tray goods on to the load carrier by pushing. This ensures that the picking movement is
Convincing retrofit solution
ETP is not just suitable for new logistics centres; Witron points out that it can also be implemented with no special effort in existing buildings and systems, even during operation. Witron adds that ETP is also of interest as a solution for modernisation projects. ETP requires a building height of six metres or over for installation. Because of its modular design, ETP is flexible in terms of both length and width. It is also said to be technically easy to integrate into an existing IT system, and because of its transparent operating processes and the visual tools employees only require a short training period.
