Double sheet recognition
The double sheet recognition process is performed by means of
three sensors in the C arm of the BendMaster.
When a part is picked up, its weight is measured and compared
with the reference value from TruTops Bend.
Each time a workpiece is picked up by the BendMaster, its
weight is measured and compared to the reference value so that
it does not go unnoticed if a double-sheet is picked up.
The minimum permissible weight of a sheet is 400 g.
Note
Double sheet recognition with a pallet scale is carried out on
BendMaster systems which do not have the integrated double
sheet recognition option.
Pallet scales for double sheet recognition Fig. 38423
Double sheet recognition is carried out using pallet scales. When
a part is picked up, its weight is measured and compared with
the reference value from TruTops Bend.
You can tell whether one or more workpieces have been picked
up by the BendMaster each time a workpiece is picked up by
the reduction in weight on the pallet scales.
The measurement range of the pallet scales is 0 to 1500 kg.
The maximum load must not exceed 3000 kg (e.g. when using a
stacker for loading). The minimum permitted weight of a blank is
200 g.
