Pick-to-Light

When comparing picking methods such as pick-to-light, pick-by-voice and pick-by-scan, it is important to consider the advantages and disadvantages of each method.

Pick-to-light provides visual guidance for warehouse staff, resulting in fast and accurate picking. This method is particularly well suited to environments where high accuracy and efficiency are required, such as the pharmaceutical industry.

In addition, the world's first mobile pick-by-light system "ISAC" was developed, which adapts flexibly to different warehouse layouts and ensures fast and intuitive picking using computer vision and laser spotlight.

Pick-by-Voice, on the other hand, enables "hands-free and eyes-free" order picking, with employees receiving instructions via a headset and confirming them by voice input. This method is particularly suitable for environments in which the employee's hands must be free, e.g. when picking heavy or bulky items. This method can be very tiring for the employee, as they have to concentrate on the system's instructions during order picking. Teaching voice input is also time-consuming.

Pick-by-scan uses barcode scanners to identify items and locate storage locations. This method is more cost-effective and flexible than pick-to-light, but requires some employee training and can be prone to errors if barcodes are damaged or illegible.

Pick-by-vision is an advanced technology that uses augmented reality (AR) to improve the picking process in warehouses and distribution centers. Employees wear AR glasses or headsets that display visual instructions directly into their field of vision. These instructions provide information about the items to be picked, their storage locations and the most efficient way to get there.

Ultimately, the choice of the optimal picking method depends on the company's specific requirements and circumstances, and the pros and cons should be carefully weighed up.

Since 2024, a mobile pick-to-light system has been available in addition to the classic pick-to-light system. It was presented for the first time by CAPTRON SOLUTIONS under the product name ISAC at LogiMAT.

In contrast to classic pick-by-light, where the light signal is mounted on the shelf, the picker carries the light signal with him on the picking trolley. This eliminates the need for complex installations and the high purchase price due to the hardware required. This can quickly minimize the actual benefits of a pick-by-light system, especially in large warehouses.

Special codes are used, which can simply be stuck to the material locations as labels. Using a camera integrated into the system, the mobile pick-by-light can now orient itself using the codes. To do this, it uses them to create a digital map of the warehouse with centimeter accuracy as it passes by. A digital twin, so to speak.

This data can be used to plan optimal routes and the system guides the picker quickly and efficiently through the warehouse via the intuitive graphical user interface. When the picker reaches the desired storage location, the built-in light beam on the picking trolley is activated and points to the corresponding code on the compartment.

The intuitive operation of the system makes it easy for pickers to find the next storage location.

When implementing pick-to-light systems, there are some important aspects to consider to ensure a smooth process and maximum efficiency.

Firstly, it is important to carefully consider the selection criteria and ensure that the chosen system meets the specific requirements of the business. This includes considering factors such as warehouse size, the type of items stored and the complexity of the picking processes.

Installation of pick-to-light systems should be carried out by experienced professionals to ensure proper function and integration. Thorough training of warehouse staff is essential to ensure that they can use the system effectively and understand all its functions.

In addition, best practices should be developed for smooth integration into existing warehouse processes, including optimizing workflows and adapting to new working methods.

By following these implementation tips, the introduction of pick-to-light systems can be successfully implemented and lead to an increase in warehouse management efficiency.
