New standards for production plant

Rational and effective production of insulating blocks

Fig. 1 The depalletizing machine is designed to handle concrete blocks which are stacked lengthwise and crosswise on the pallet.

Fig. 2 The block inserter functions as a robot arm, synchronizing the insertion of the concrete blocks with the advance of the
ISO line.

Fig. 3 The foam pistol injects polyurethane foam between the concrete blocks. The foam is produced without use of CFC gases or ozone-depleting substances.

Fig. 4 The polyurethane foam hardens while the ISO block is
moving 35 m through the ISO line. Running through the line the blocks remain visible from outside.

Fig. 5 The palletizing machine stacks the finished ISO blocks on pallets, which are subsequently wrapped in plastic foil.
The ISO blocks are now ready for dispatch.

Fig. 6 The pallets with the finished ISO blocks are accumulated on the outdoor chain conveyor, from which they are taken to the storage area.

The Danish company fibo intercon a/s is currently putting the finishing touches to the running-in of a new plant for production of insulating blocks at the Norwegian company maxit Leca Borge. The plant is unique. It is fully automated and has a cycle time of only five seconds producing insulating blocks which meet the new, tighter insulation requirements and dimensions. A combination which has not been seen in this type of plant before.

In the past few years, requirements concerning the design of insulating blocks (called ISO blocks below) have been tightened. The insulation requirements have been tightened, and the demand for ISO blocks in dimensions other than the traditional ones has increased; maxit Norway therefore started looking for a partner to develop and deliver a plant which was able to produce in accordance with the new standards. However, the old production line in Borge was no longer able to keep up with the Scandinavian markets’ demand for ISO blocks. In spite of several conversions, the plant did not have...
