Fully automated IG production - Direct linking of cutting and IG line with software-controlled addition of laminated glass

Harald Biel

After implementing the cutting control system DynOpt in connection with HEGLA SortJet five years ago, long-term studies have not only confirmed the results presented here but it has become evident that due to the constant optimisation of the system which had been piloted then by Wolff+Meier Glaswerke, even better processes – and therefore savings – could be achieved, especially in the fields of
• maintaining defined sequences
• minimising the material consumption
• saving of labour cost
• packing-optimised sequencing
• flexible cutting and easy addition of rush orders, remakes, and special glass types

At the same time, experience in other companies who are using a direct link between sorting line and IG line, are showing promising results. Moreover, we and our software partner ALBAT+WIRSAM saw additional saving potential by optimising the laminated glass cutting and improving the integration of the laminated glass stream in IG line loading. Wolff+Meier therefore decided to adapt the original solution to the new, improved possibilities that have opened up by the refinement of DynOpt and HEGLA’s technology.

Since this April, Wolff+Meier have taken the following optimisation and restructuring measures:
• direct link between HEGLA SortJet and the IG line
• up to three sheets in one Sortjet slot
• unproblematic production of triple IG
• integration of a HEGLA laminated glass Remaster in connection with a HEGLA ProLam in the laminated cutting area
• full integration of the laminated glass stream in the DynOpt control process – fully automatic, selective preliminary cutting of laminated glass and special glass types which, fully automatic as well – are added to the sorting buffer.
• Integration of a quality scanner into the IG-line
