Side Guarding Configuration On Agvs - Siemens SIMATIC FS600 Instruction Manual

5.7.10

Side guarding configuration on AGVs

All previous considerations and the Chapter 5.7.9 calculation for calculating the
detection zone measurements of an AGV application also apply for side guarding on
AGVs. With AGVs that drive along conveyor segments it should always be ensured that
big enough undercut is provided (see also, details in Chapter 5.4.4). If the structure of
the conveyor segment does not allow an undercut, then it must be assumed that a
person is in the space between the vehicle and the conveyor. This is especially the case
with spaces of more than 100 mm. This person in the space between vehicle and
conveyor should be detected simultaneously with a person in the driveway, which must
be taken into consideration with the dimensioning of the detection and warning zones.
The same safety distance calculations therefore apply.
A laser scanner resolution of 150 mm is required to detect an entire person. This safety-
relevant setting is automatically set in the SIMATIC FS600 Parameterization Software
LS4soft configuration and diagnostics software with selection of the "person detection"
presetting. The definition of a reference contour as with access guarding is not
necessary, as the approach of the person to be protected is made in the direction of the
detection zone! If the conveyor segment height is over 500 mm and the distance
between vehicle and conveyor is more than 100 mm, then the detection zone between
vehicle and conveyor can be aligned. With conveyor segment heights below 500 mm
there is the increased danger of the conveyor segment being crossed over. In this case
the alignment of the detection zone with the conveyor edge guarantees detection of a
person at this point. If a laser scanner resolution finer than 150 mm is additionally
required for the safe position detection of the load, then this can also be selected in this
application. The person in the in between space continues to be safely detected.
