Pick-to-light system: Transforming warehouse automation
Posted :

Modern warehouses strive for higher productivity. Hence, every advancement in accuracy and speed is an opportunity to excel. The pressure to deliver accurate and on-time orders has never been higher. However, manual picking processes fall short in accuracy and speed.

The cost of order picking is estimated to be as much as 55% of the total warehouse operating expense. – ResearchGate

Pick-to-light technology is the answer. It enhances warehouse productivity by guiding workers with LED light cues to each item. This helps businesses minimize errors and maximize efficiency. So, let’s dig deeper into this technology to understand its working and benefits.

Challenges faced by traditional picking system

High error rates

Manual picking processes often lead to picking errors. These errors include selecting the wrong item or incorrect quantities.

  • Impact:
    • Increased customer dissatisfaction due to incorrect orders.
    • Higher costs associated with returns and re-shipping items.

Time-consuming processes

Manual picking typically involves workers searching for items based on paper lists or screens, leading to inefficient use of time.

  • Impact:
    • Delays in order fulfillment leads to decreased customer satisfaction.
    • Inefficient use of labor resources affects overall productivity.

Labor-intensive operations

Traditional picking relies heavily on manual labor, requiring workers to move extensively throughout the warehouse.

  • Impact:
    • Elevated labor costs due to extensive manual involvement.
    • Increased risk of worker fatigue and subsequent errors.

Scalability challenges

As order volumes increase, scaling manual operations can be difficult and costly.

  • Impact:
    • Difficulty in managing peak demand periods without significant investment.
    • Potential loss of business opportunities during high-volume seasons.

Longer lead times

The combination of manual processes and high error rates often leads to longer lead times for order fulfillment.

  • Impact:
    • Adverse effects on customer satisfaction due to delayed order processing.
    • Reduced competitiveness in a fast-paced market environment.

What is pick-to-light system?

Pick-to-light technology utilizes visual indicators, typically LED lights. It guides warehouse operators to locate and pick items from shelves or storage areas. Each item location has a light that illuminates when an order is ready to be picked.

Functionality: How it works?

  • The pick-to-light system activates the corresponding lights when the order is generated. It is displayed at the specific locations of the items that need to be picked.
  • Operators follow the illuminated lights to the correct pick locations, ensuring they select the right items in the correct quantities.
  • Some systems may also include displays showing the number of items to pick or additional instructions.

Components:

  • LED lights: These are installed at storage locations, illuminating to indicate which items to pick.
  • Control system: A centralized software system that manages orders, coordinates light activation, and tracks inventory levels.
  • Barcode scanners or RFID: It is used to verify picked items and update inventory in real time.

Benefits of pick-to-light system

  • Increased picking speed: By providing visual cues for pickers, the system accelerates order fulfilment. It helps in reducing picking time.
  • Improved accuracy: The LED indicators guide pickers precisely. This reduces human errors and improves order accuracy.
  • Enhanced productivity: Handle higher volumes of orders in less time.
  • Lower training costs: Reduce the learning curve for new employees.
  • Better inventory control: Real-time updates and accuracy help maintain optimal stock levels and reduce discrepancies.
  • Scalability: The system can be easily adapted to growing warehouse needs. It can support varying order volumes and product types.
  • Reduced labor costs: Optimize workforce utilization and reduce labor expenses.
  • Improved warehouse utilization: The system can lead to more efficient use of space and resources by streamlining workflows.
  • Faster order fulfillment: Quick and precise picking allows for faster order processing. This leads to reduced lead times and enhanced customer satisfaction.
