Mobile Safeguarding Of Automatic Guided Vehicles; Protecting Transporter Trolleys Against Collisions - Siemens SIMATIC FS600 Instruction Manual

4.4

Mobile Safeguarding of Automatic Guided Vehicles

For this application, the SIMATIC FS600 Laser Scanner is installed on automatic guided
vehicles in order to monitor the vehicle path. The aim is to detect people or objects in the
path of the vehicle and to automatically bring the vehicle to a halt. Safety systems
available up to now, such as bumpers or safety bars, have allowed only very low driving
speeds to be maintained. In contrast, using the SIMATIC FS600 Laser Scanner as a
non-contact "advance bumper" results in the creation of a substantially larger safety
zone.
The vehicles can move faster, and down times are reduced to the necessary minimum.
SF1= Detection zone 1 for slow speed
WF1= Detection zone 2 for high speed
a = Traveling straight ahead

Please comply with the safety notes in Chapter 3. For an example of how to calculate
detection zone measures, please refer to Chapter 5.7.9.

Protecting Transporter Trolleys against Collisions

Transporter trolleys are generally guided along a system of rails or grooves in the floor.
Hence the vehicle paths are usually just slightly wider than the trolleys themselves. This
represents an increased hazard for people, since it is impossible to get out of the way of
the trolley. For this reason, transporter trolley are used in enclosed areas equipped with
suitable access safeguarding.
