Material flow solution
100 shoeboxes per minute
The Conveyor Handling Company (CHC) has implemented a modern material flow solution at Distribution Management Group Inc (DMG). At the heart of the solution for a new distribution center in Cranberry, New Jersey, is a modular crossbelt sorter from Interroll. The requirement was for the material flow system to handle 100 shoe boxes per minute.
"Originally, we were supposed to design a distribution center based on the existing facilities," explains Rich Rittermann, Vice President Operations at CHC. "In this concept, an employee pushes a cart through the warehouse and collects shoe boxes. He then takes the full cart to the central sorting area, where other workers take the boxes from the incoming carts and pack the goods until each order has been processed. However, this labor-intensive process would not have been able to cope with the expected order volumes. So the first step was to convince the customer to use an automatic sorting system."
Robust, mechanical design
Rittermann learned at the right time that Interroll was working on a shoe distribution center in Mexico where Interroll's horizontal crossbelt sorter was being used. Unlike traditional crossbelt sorters, Interroll's solution is based on a robust, mechanical design to transport goods to the correct chute. This design saves electricity costs, simplifies maintenance and ensures reliability and longevity.
Sorter designed on two levels
The sorter can also be used for sensitive goods such as eggs and yoghurt, but can also move heavier bags or containers. Thanks to its modular design, the horizontal cross-belt sorter is compact and can be easily adapted to existing spatial conditions. In this application, CHC has designed the sorter on two levels, thus maximizing the throughput of the system without requiring more floor space.
"The collaboration between Interroll, DMG and the CHC team worked very well," reports Rittermann. "This solution is a big step forward for our customer. Between 15,000 and 30,000 pairs of shoes are now delivered every day, which means that the system is far from reaching its capacity limit. At the beginning of the project, the new technology had to work faster and more efficiently. A system was required that would allow shoes to be picked and dispatched on the same day, which is exactly what we delivered."
