Intelligent Pick-to-Light System (PTL for short) is a paperless intelligent picking assistance system applied in warehousing, logistics and production & distribution. It guides operators to complete order picking/sorting quickly and accurately through indicator lights and digital displays, greatly improving operational efficiency and accuracy.
Working Principle
The system integrates with Warehouse Management System (WMS), ERP and other platforms. It automatically activates the indicator lights at target storage locations according to order tasks and displays the required picking quantity on electronic labels.
Operators pick goods following the light instructions and press the confirmation button upon completion. The lights then turn off, and the system synchronizes inventory updates and task progress, realizing “picking by light, no need to search for goods”.
Main Components
Electronic shelf labels (with indicator lights, display screens and confirmation buttons)
Zone controllers
System management software
Data interfaces with WMS/ERP/MES
Core Features
