Eine solche Maschine ist durch DE 296 11 728 U1 bekannt. Mit einer derartigen
Maschine können Steine oder Rohlinge ganz unterschiedlicher Breiten auf ein jeweils
gewünschtes Maß beschliffen werden, was mit einem einzigen Transportband mit
festliegender Breite allenfalls in ganz geringem Umfang möglich wäre - vgl. hierzu
Seite 3, Absatz 2. Dabei besteht noch der Nachteil, daß ein konstruktionsaufwendiger
und zerklüfteter Aufbau vorliegt und insbesondere durch die zwischen den beiden
Maschinentischen vorhandene Verstellspindel eine Vibrationsübertragung zwischen
den beiden Maschinenseiten begünstigt wird. Das Transportsystem erschwert die
Zugänglichkeit. Außerdem ist aufgrund der Transportketten ein verhältnismäßig großer
Verschleiß und Geräuschpegel gegeben sowie ein verhältnismäßig hoher
Wartungsaufwand erforderlich. Such a machine is known from DE 296 11 728 U1. With such a

Eine besonders bevorzugte Ausbildung als Planziegel-Schleifmaschine ermöglicht bei zweisträngiger Objekt-Unterstützung die Einstellung von Kalibriermaßen/Schleifbreiten im Bereich von etwa 200 - 500 mm. Selbstverständlich kann eine erfindungsgemäße Maschine auch für größere Arbeitsbreiten, beispielsweise bis 800 mm, ausgeführt werden. A particularly preferred design as a face brick grinding machine enables two-strand object support the setting of calibration dimensions / grinding widths in the range of about 200 - 500 mm.

Lage zwischen einem maschineneigenen Transportsystem, welches aus einer
angetriebenen unteren Fördereinrichtung 3 und einer dazu entsprechend der Baustein-Höhe
in der Höhe einstellbaren Niederhalteeinrichtung 4 besteht, eingespannt sowie
durch mindestens eine Planierstation 5 bzw. 5,5' bewegt und dabei seitlich bearbeitet,
insbesondere auf ein vorgegebenes/vorwählbares Kalibriermaß geschliffen. Wie aus
Fig. 2 und 3 zu ersehen ist, ist die Fördereinrichtung 3 breitenmäßig geteilt und weist
vorzugsweise zwei objekttragende Umschlingungstriebe auf, welche quer zur
Transportrichtung T verlagerbar und dabei auf unterschiedliche Stützweiten einstellbar
gehaltert sowie synchronlaufend angetrieben sind.The
Die erfindungsgemäße Planiermaschine weist ein als Ganzes mit 6 beziffertes
Grundgestell auf, welches vorteilhafterweise symmetrisch aufgebaut und für eine
rechts- oder linksseitig bedienbare Maschine verwendbar ist. Am Grundgestell 6 ist
seitlich neben dem maschineneigenen Transportsystem sowie etwa mittig zwischen

Halterung 8 für eine als Ganzes - insbesondere mittels eines als Balgzylinder
ausgeführten Druckmittelzylinders 9 - abgefederte mittige Aufhängung der
Niederhalteeinrichtung 4 trägt. Die Symmetrieebenen von Transportbahn und
Niederhalteeinrichtung kongruieren und liegen auf der Maschinen-Transportachse M.

eine Planierwerkzeug-Seitwärtsverschiebung im erforderlichen
Maße initiiert. Die Meßeinrichtungen 19, 19' einer jeden Maschinenseite werden durch
die Maschinentisch-Verschieung in eine vom jeweiligen Kalibriermaß/Schleifbreitenmaß
vorgegebene Grundstellung verfahren. Die Meßeinrichtungen 19, 19' sind als
Laserstrahl-Meßeinrichtung ausgeführt und weisen einen Sender und einen Empfänger
für die Laserstrahlen auf, welche sekantial (nicht dargestellt) den Umlaufkreis des die
Planierarbeit durchführenden Rotors oder den Funktionsbereich eines Schleifbandes
queren. Bei der bevorzugten zweistufigen Planiermaschine ist der seitwärtsgerichtete
Versatz zwischen vorderem und hinterem Laser 19, 19' einstellbar.Both machine tables 12 have for each leveling device (also from one

- Machine according to claim 9, characterized in that the two measuring devices (19, 19') of each supporting table (12) take the form of a laser beam measuring device, the laser beams of which extend secantly relative to a grinding rotor circular orbit - in the present case provided above the path of motion of the article to be planed - and for multistage planing a sideward-directed offset is (pre)adjustable between front and rear laser.
