The strand unloader is managed by the software creating an unloading program to place the piece files on the appropriate belts and to verify the grip positions and the areas used.

Execution working

The software verifies that the slab is divided into horizontal files (with tolerance of a few degrees on the direction of the cuts), that the size of the pieces is within the limits and sets the order of the movements and the row of vacuum cups to be used.
Movements with the vacuum cups toward right or left, pieces that intersect and similar conditions cancel the creation of the program that will not be unloaded automatically.

The gripping zones are colored in green while those not in gripping are colored in red.
The parameters are set by the technician at the start of the machine and remain fixed.
