This reduces the need for manual handling of products and helps optimize warehouse space. |
2.2 Pick Location Identification |
One of the first tasks in the picking process is identifying the correct location of an item in the warehouse. Barcode scanning robots can be integrated with the warehouse management system (WMS) to identify the pick locations. These robots use barcode scanning to check the labels on shelves, bins, or racks that store the products. Based on the real-time data from the WMS, the robot can navigate to the exact location where the product is stored, ensuring that the correct product is selected and brought to the packing area. |
By using barcode scanners, robots can quickly identify the correct shelf or bin without human intervention. This capability reduces the chances of selecting the wrong product and streamlines the picking process. Additionally, barcode scanning robots are able to handle multiple products at once, increasing overall picking efficiency. |
2.3 Pick Verification |
Once a product is picked from a shelf or storage location, barcode scanning robots are used to verify that the correct product has been selected. After a robot or human worker picks an item, the barcode scanner on the robot scans the product's barcode to verify that it matches the order details. This is crucial for preventing errors in order fulfillment, such as shipping the wrong product to a customer. |
The scanning robots compare the scanned barcode against the order database in real time. If a mismatch occurs, the robot can alert the worker or system, prompting them to reselect the correct item. In the case of autonomous robots, the system can redirect the robot to a different location to pick the correct product, ensuring that only accurate orders are processed. The barcode verification step is a key safeguard against costly mistakes in the order fulfillment process. |
