Product Overview

The full-automatic light-directed put-to-light wall (also referred to as automatic put wall) is a high-efficiency automated order sortation solution purpose-built for wave-picking order consolidation in modern distribution centers and e-commerce fulfillment facilities. It integrates LED digital light modules on each dedicated order slot, paired with automatic roller conveyors, photoelectric sensing units and a central control system to visually guide operators to distribute bulk-picked goods into corresponding order slots with precise quantity indication.

Featuring automatic inbound feeding, intelligent task allocation and instant operation confirmation, it eliminates manual order verification and paper-based sorting lists, drastically cuts unnecessary operator walking and labor intensity, and delivers a major boost to order consolidation throughput. It seamlessly integrates with WMS/WCS platforms and upstream/downstream conveyor systems, making it ideal for high-SKU, high-volume order processing scenarios, and supports both manual put-to-light operation and semi-automatic assisted workflows.

Core Advantages

Automatic inbound feeding combined with light-guided sortation eliminates manual material handling, improving per capita sortation efficiency by 50% to 80% compared with manual operation
Sorting accuracy up to ≥99.9%, effectively eliminating order misplacement, missing items and quantity deviations, and greatly reducing reverse logistics costs caused by order errors
Modular slot design allows flexible adjustment of slot quantity to match business growth and seasonal peak demand
Seamless integration with WMS/WCS systems and upstream/downstream conveyor lines, realizing automatic wave order distribution and full-process data traceability
Fully paperless workflow removes the need for printed sorting lists, cutting on-site document management costs and avoiding document loss or on-site confusion
Ultra-short operator onboarding cycle; new staff can operate independently within 30 minutes, with no need for long-term memorization of slot positions or SKU information
Supports multiple sortation strategies including single-SKU wave, multi-SKU wave and cross-dock sortation, adapting to different order structure characteristics
Comprehensive operation data statistics including per capita throughput, sortation error rate and order processing time, supporting fine-grained warehouse performance management

Typical Application Scenarios

01/

E-commerce Order Consolidation Centers: Automatic put-to-light walls are widely deployed in post-picking order consolidation zones for multi-SKU small parcels. Working with wave picking systems and roller conveyors, they realize fast and accurate distribution of bulk-picked goods to individual orders, effectively handling order surges during promotional events and significantly reducing order fulfillment cycles.

02/

Pharmaceutical & Medical Device Distribution: Complying with GSP management requirements, the system supports batch and expiry date traceability throughout the sortation process. Paperless operation reduces cross-contamination risks, and precise quantity control ensures safe and compliant distribution of pharmaceutical and medical products.

03/

Chain Retail Store Replenishment Sorting: For multi-store batch distribution, the put-to-light wall distributes bulk goods to corresponding store orders in one pass, enabling fast batch allocation of FMCG, food and daily necessities, and shortening the delivery cycle from distribution centers to offline stores.

04/

Fast Moving Consumer Goods Distribution Hubs: The tote-type automatic put wall supports continuous high-throughput sortation of fast-turnover consumer goods. The automatic full-tote discharge function directly connects with downstream packaging and shipping links, realizing uninterrupted order processing.

05/

3C Electronics & Apparel Sorting: For industries with massive SKUs and diverse specifications such as electronics and apparel, the system realizes accurate order consolidation of different models, sizes and styles. It avoids mixing errors and fits the characteristics of high turnover and seasonal peak demand.
