... Pesa double in-motion scales DWL

The time factor plays a crucial role in logistics. In order to allow speedy yet at the same time economical transport, the collected packages must be assigned to their destinations as efficiently as possible in standardised processes.

Pesa double in-motion scales DWL

Depending on the package distribution curve and weighing belt
combination, the Pesa DWL allows an increase in the throughput
capacity of between 25 and 30%.

No more unnecessary throughput limits

In the past, dynamic in-motion scales were the "bottleneck" in the conveyor systems of package sorting centres. Conveyor belt speeds of 3 m/s and a sorting capacity of 10 to 12000 packages / hour seemed unattainable. The reason: The packages of different lengths (200-1200 mm) were fed to the scales chaotically. Because it was necessary to use the package with the largest dimensions (L x W x H) for dimensioning the in-motion scales, and because only one package could be on the weighing belt at any one time in order to obtain an exact weight. This resulted in large gaps between front edge and front edge when small packages were passing through. The throughput per hour was reduced at a constant speed.

With two dynamic scales on the other hand, activated depending on the package length, it is possible to significantly reduce the gap between the packages. This is exactly the principle on which the Pesa DWL works, with an upstream conveyor system allocating the packages depending on their length.

Length Distribution (Test Shpt vs Shpt Data)

The distribution curve of the packages based on length (mm) and frequency (%) is an important indicator of a conveyor and sorting system's efficiency. It shows that with Pesa DWL, most of the packages can be weighed via the first weighing belt with a smaller gap, with the remainder being weighed via the first and second weighing belt.
