(1) Picking by order in the “fruit picking” style. Orders correspond to picking lists, and pickers pick directly according to the picking lists. This is usually applicable to large, heavy, special-shaped items, whole boxes, few SKUs, urgent orders, etc. In the relay picking, the turnover box moves along the picking line, the goods are picked and placed in the turnover box, and finally transported to the packaging table.
(2) Picking and sorting (“fruit picking” style). This is applicable to a large number of scattered orders with low overlap of goods, light and small items, few SKUs per order, and non-hot-selling orders of single products. Picking carts can be used. One cart can have 10-20 picking baskets. The basket positions match the orders. Pickers take the corresponding products and put them into the corresponding picking baskets in turn. After the baskets are full, they are sent to the review table. The packing personnel directly review and pack according to the order without secondary sorting.
(3) “Sowing” style: picking first and then sorting. First, merge the orders, then pick the goods. The cage truck will perform secondary sorting and review at the packing table, narrowing the search range of the goods required for each order to one batch. It is suitable for small and medium-sized warehouses, and is suitable for situations where the average order line is small, the product overlap rate is high, the unit price of the goods is high, the daily shipment volume is not high, and the review personnel are familiar with the goods and can quickly locate the products. The number of orders for a single order picking should not be too large, otherwise a larger secondary sorting table is required, and manual review is prone to errors. The specific number of merges depends on the product specifications and the capacity of the picking truck.
(4) Aggregate and sow (“seeding” style). Use the “picking truck + turnover box” method to pick goods, associate the turnover box with the order SKU, and pick the goods in turn and put them into the designated turnover box. After a wave of picking is completed, the turnover box is transported to the sowing shelf, the turnover box barcode and product barcode are scanned, and the goods are placed in the sowing position corresponding to each order. Secondary sorting is also the process of reviewing the quantity of the first picking. It is suitable for B and C category picking with few SKUs, medium order quantity, high requirements for picking accuracy, as well as hot-selling products and high overlap rate order scenarios.
(5) Single product operation. Single product orders are common in e-commerce promotions. A large number of customers only order a single product. They are separated from other types of orders, and the single products are accumulated and combined for picking. They are picked directly in the storage area and then sent to the packing station for review. The product barcode is scanned and the orders are directly printed and packaged one by one. If the label is pre-printed, different waves are added for different express delivery companies, the waybill number is associated with the order, and the order quantity is marked. The waybill is scanned during review and the packaging is completed according to the system prompts. This type of batch picking method is also applicable to Class A goods with large order quantities.
(6) Zone picking. Zone picking is suitable for large single warehouses. Fixed pickers are assigned according to the zones in the warehouse. Since the pickers pick goods in the same fixed area for a long time, the goods are familiar and it is easy to find the corresponding storage location. Split the picking collection list into multiple small picking collection lists, each of which corresponds to a picking area. Set up a Pick-to-belt conveyor belt at the end of different types of storage areas to transport and merge the turnover boxes of the picked items into a collection list turnover box, and then send the collection turnover box to the distribution or packaging workbench.
