Since the introduction of the LASCO vario-block press technology in 2006 the system for the economic production of supplementary or vario-blocks has been further developed into the most flexible production line for the element system in close cooperation with our customers.
Pressing and ejection of the wall thickness formats 115 mm (picture left) and 300 mm (picture right).
LASCO is now offering a modular production system, which is unique in the market and complementing the original vario-block press by:
• Green block saws
• Saws for slits in brickwork
• Green block crushers with overspill recovery
• Printers for numbering blocks in product identification
• Stacking robots
• Code-decode systems for curing wagons
The whole process control is handled with a wall unitizing software which fol- lows the architect’s construction drawings and first creates brick laying plans. These are used for the creation of data sets of optimized batches for the con- trol of the vario-block press line via the planning software.
One of the most prominent further developments is the Vario-block press PSP compact
The PSP compact is conceived to complement the tried and tested PSP 460 and fits well into the modular concept of vario-block production lines. The ba- sic idea here is the optimization of the mould system for applications, in which up to four different wall thicknesses or shapes are used.
- Unlocking of the mould
- Shifting of the side plates
The mould box is not shifted in case of a format change, but pushed in via a mould changing system and hydraulically clamped like in our other sand-lime block presses.
For a format change, the two side plates of the mould are shifted symmetrically to the middle of the press inside the mould box, then locked and thus deter- mine the wall thickness. The possible pattern of the side plate adjustment then corresponds with that of the wall thicknesses (115 mm, 150 mm, 175 mm,
200 mm, 240 mm, 300 mm). Simultaneously with the adjustment, the two head plates of the upper and lower punch are also changed fully automatically. The new mould system of the vario-block press allows a compact design of the press and shortens the time of a format change.
