Batch formation in picking
This post is also available in: Deutsch (German)
Batch formation during picking, also known as batch picking or multi-order picking, is a form of two-step picking and is used in picking forms such as series-oriented, parallel picking. Requirements from several individual orders are combined in batches and the goods are then consolidated by order.
In the following, the batch formation during picking will be described using a two-stage picking process with batch buffer and sorter.
This type of picking includes, in sequence, the following operations:
- Forwarding of customer orders calculated by the ERP system to thewarehouse management system.
- Dispatching of the picking.
- Formation of pools.
- Distribution of batches spread over a day.
- Processing of rush batches.
- Optimization of tours.
- Start of an MDE-guided tour or a tour with accompanying documents.
- Transmission of information to the material flow control system.
Processing of the batch formation
Batch picking can be handled in two ways. Either online with a mobile data collection device, which handles the error quantity processing, the zero-crossing and the work progress report via the warehouse management system, or with a goods receipt/issue slip, in which the warehouse management system receives the reports via a production data collection system.
In any case, a reservation of the tray buffer or batch buffer, a check of the filling level, a recording of the batch status and a message of the work progress is made. If the batch status is complete and the work progress is finished, there is usually a dynamic batch change. Subsequently, all picking bins belonging to the batch are removed from the sorting lines and transported to the sorter. The sorter control then receives all necessary information.
This is followed by the work steps:
- Sort by sales orders
- Initiation of the manual packing process
- Printing the delivery bill and label for CEP services, such as UPS or DHL
- Monitoring of the work progress
The orders are then transported.
Depending on the operator’s approach, the transport is carried out according to SAIL, a system architecture for intralogistics.
