By utilizing wireless light module that can be operated by five people, we can achieve a reduction in lead time for sorting large items.

Introduction video of the case study.

Wireless DAS system that supports multiple operators for simultaneous sorting.

Efficiency in picking has improved, allowing for an increase in output and a reduction in lead time without the need to increase manpower.

Background of the implementation

Due to an increase in volume and difficulty in recruiting, the current list picking is no longer sufficient.

It has been decided that the volume of goods will roughly double, making it difficult to hire more people due to recruitment challenges, and the current list picking method is no longer sufficient. By using wireless light module that do not require a specific sorting location, we can prevent congestion in the warehouse layout and address the situation through systematization.

Shorten the picking time was needed.

Due to changes in contract terms with customers, it has become necessary to pick and pack on the same day as the arrival of the goods within a short time.

There are many items with large sizes.

We are considering using wireless indicators that allow for flexible handling, as we deal with large items such as paper and clothes drying poles.

There was a concern that with the simultaneous DAS for multiple people, there might be a risk of accidentally pressing the button for someone else's task.

When multiple people were working on the DAS at the same time, there was a risk of accidentally pressing the button for the color activity for another person, so the wireless light module button was operated in combination with the HHT to prevent accidental pressing of buttons.

Impact after implementation

The warehouse layout was optimized to improve work efficiency.

By utilizing the flexibility of the wireless light module and devising the layout of the warehouse, we were able to complete the tasks that were originally planned for multiple batches in one batch, resulting in increased efficiency.

A multi-work system for five people working simultaneously was developed by integrating scanner-based inspection.

We achieved simultaneous work for five people using a 5-color multi-work light module. Work completion is synchronized with scanner inspection without pressing the light module button, enabling multiple simultaneous tasks without color errors.

Paperless operations were achieved.

Not having to carry paper or pencils around has improved the handling of tasks. This has led to paperless operation, making it easier to manage.
