New SLS modules – train control and 3D navigation

Over the past few months, iFD has been working intensively on the development and implementation of two new SLS modules. Visitors to LogiMAT were already able to get an initial overview of the features. Here, we would like to present the new features to you in detail once again.

Tugger train control

The use of tugger trains is not a new concept in intralogistics. Operating along fixed routes allows for simultaneous material supply and removal, thereby enabling a significant reduction in transport movements. Within the context of Logistics 4.0, the focus at many companies is now shifting towards the software-supported, efficient control of tugger trains. With the iFD tugger train module, these transport operations can now also be controlled optimally and, where required, dynamically.

The iFD tugger train module can be implemented in two variants/configurations. Static control optimises operations along a fixed route and documents all pick-ups and deliveries. In addition, the driver is assisted in the composition of the train with regard to the selection and sequence of tuggers. Stops for which there are no orders in the generated route are not visited. A dialogue box displays the stops and the trailers to be unloaded to the driver, who then confirms the process steps via the terminal. As in the forklift guidance system, priorities for the supply and collection at individual stops can also be defined here.

Dynamic control takes this a step further. Here, the convoy does not follow a fixed route; instead, the system calculates the optimal route and the composition of trailers and load carriers based on demand and priorities. This significantly increases the flexibility and efficiency of route convoy control, as unnecessary journeys are avoided, utilisation is optimised and supply can be managed more precisely.

3D navigation.

In addition to route, time and capacity utilisation optimisation, which the iFD-SLS already provides as standard, assistance systems for forklift drivers are also becoming increasingly important in complex logistics environments. In block storage facilities in particular, it is not always easy for the driver to maintain an overview. One solution to this problem is the module for 3D navigation and automatic load carrier tracking, which iFD has developed in collaboration with a partner.

Forklift tracking is carried out by a 2D laser sensor that measures against the contours of the building and objects whilst the forklift is in motion. This dynamically captures the surroundings. Additionally, information on height coordinates is collected via the sensor system. Using this data, the pallet to be picked up and the route to it can be displayed to the driver in 3D. Recording of pick-ups and drop-offs takes place automatically in the system without the need for scanning. This results in further time savings.

As a result, the movement of all load carriers is recorded in real time. Search times and error correction costs due to incorrect scans are eliminated.
