Abstract

A machine is disclosed for trimming the sides of building blocks or the like, in particular dried green bricks (Z) or baked bricks (Z) that are centred, vertically clamped and thus conveyed through at least one trimming station with laterally arranged tools. The invention is characterised by a transport device with two endless belts under compression load made of flexible material and designed as conveyor and compression belts (2, 3). The conveyor and compression belts (2, 3) are forcibly guided in the lateral position by at least one groove and spring connection (7a, 8), in particular a keyway and V-rib connection, and run on a rail- or plate-shaped flat support (9) at least in the area of the trimming tools (5).

Beschreibungdescription
Die Erfindung betrifft eine Maschine zum seitlichen Bearbeiten von Bausteinen oder dgl., insbesondere getrockneten Ziegelformlingen oder gebrannten Ziegeln, die justiert und höhenmäßig eingespannt durch mindestens eine Bearbeitungsstatioπ mit seitlicher Werkzeug-Anordnung transportiert werden.The invention relates to a machine for the lateral processing of building blocks or the like., In particular dried brick moldings or fired bricks, which are transported in an adjusted and clamped height by at least one processing station with a lateral tool arrangement.
Bei den in der Praxis bekannten Ziegel-Schleifmaschinen besteht noch der Nachteil einer mangelhaften Zwaπgsführung der zu bearbeitenden Quader (Ziegelformlinge/ Ziegel). Eine exakte Lage des zu bearbeitenden Quaders in bezug auf die seitlichen Bearbeitungswerkzeuge ist jedoch für eine einwandfreie Arbeitsausführ uπg von Vorteil bzw. erforderlich.In the brick grinding machines known in practice, there is still the disadvantage of inadequate forced guidance of the cuboids to be processed (brick moldings / brick). However, an exact position of the cuboid to be machined with respect to the lateral machining tools is advantageous or necessary for flawless work execution.
Der Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte Maschine zum seitlichen Baustein-Bearbeiten, insbesondere seitlichen Planieren von Ziegeln oder Ziegelformlingeπ zu schaffen, bei welcher die zu bearbeitenden Objekte in einer einmal justierten Lage sicher fixiert sowie in solcher Lage unverrückbar durch mindestens eine Bearbeitungsstation transportierbar sind.The invention is therefore based on the object of providing an improved machine for lateral block processing, in particular lateral leveling of bricks or brick moldings, in which the objects to be processed are securely fixed in a once-adjusted position and can be transported immovably in such a position by at least one processing station are.
Erfindungsgemäß wird dies durch eine Maschine gemäß Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention, this is solved by a machine according to claim 1. Further developments of the invention result from the subclaims.

A non-contact measuring device is preferably present which detects the machining end face 5a of each panning tool 5 and its signals for automatic leveling tool tracking can be used
Um eine exakte seitliche Planierung der durchlaufenden Zιegel(formlιnge) Z zu gewährleisten, ist erfindungsgemaß dafür gesorgt, daß die Zιegel(formlιnge) Z in ihrer durch die Justiervorrichtung J vorgegebenen seitlichen Relativlage auch wahrend der gesamten Bearbeitung (Schleif- oder Frasbearbeitung) verharrenIn order to ensure an exact lateral leveling of the continuous Zegel (form length) Z, according to the invention it is ensured that the Zιegel (form length) Z remain in their lateral relative position specified by the adjusting device J during the entire processing (grinding or milling)
In bevorzugter Weise ist das maschineneigene Transportsystem von zwei als Forder- und Druckband 2,3 ausgebildeten druckbelasteten endlosen Bandern aus flexiblem Material gebildet, welche in der Seitenlage mittels mindestens einer zentrierenden Nut-Feder-Verbindung - insbesondere eine Keilnut-Keilπppen- Verbindung - zwangsgefuhrt sowie mindestens im Bereich des/der die Bearbei- tung durchführenden Planierwerkzeuge(s) 5, insbesondere Schleifscheibe(n), über ein schienen- oder plattenartiges ebenes Widerlager 9 laufen. Das Förder¬ band 2 und das Druckband 3 sind rückseistig zumindest im mittleren Quer¬ schnittsbereich mit Keilnuten 7a versehen, in welche Keilprofilrollen 8, als Zen- trierrollen, eingreifen. Wie aus der Zeichnung zu ersehen, sind in bevorzugter Weise zwei Gleitleisten 9 vorgesehen, welche auf die beiden Seitenbereiche einwirken. Selbstverständlich kann auch eine Ausführung vorgesehen sein, wo mindestens eine Gleitleiste 9 den mittleren Querschnittsbereich unterstützt und die Keilprofilrollen 8 mit den beiden seitlichen Querschnittsbereichen zusam¬ menwirken.The machine's own transport system is preferably formed by two pressure-loaded endless belts made of flexible material which are designed as a conveyor belt and pressure belt 2, 3 and which are positively guided in the lateral position by means of at least one centering tongue and groove connection - in particular a keyway-keyway connection at least in the area of the tion-carrying planing tools (s) 5, in particular grinding wheel (s), run over a rail-like or plate-like flat abutment 9. The conveyor belt 2 and the pressure belt 3 are provided on the back at least in the central cross-sectional area with splines 7a, in which spline rollers 8, as centering rollers, engage. As can be seen from the drawing, two slide strips 9 are preferably provided, which act on the two side regions. Of course, an embodiment can also be provided in which at least one slide bar 9 supports the central cross-sectional area and the spline rollers 8 interact with the two lateral cross-sectional areas.

Die Keilprofilrollen 8 sind abgefedert gelagert. In Fig. 6 und 7 sind die symbolhaft dargestellten Federelemente mit 10 beziffert.The spline rollers 8 are spring loaded. 6 and 7, the spring elements shown symbolically are numbered 10.
In besonders bevorzugter und vorteilhafter Ausführung ist jede Keilprofilrollen- ' Lagerung mittels eines Federpakets abgefedert und dabei gleichzeitig geführt angeordnet - hierbei werden zusätzliche Führungelemente eingespart.In a particularly preferred and advantageous embodiment, each spline roller bearing is cushioned by means of a spring assembly and is arranged in a guided manner at the same time - additional guide elements are saved.
Die Andrückeinrichtung 3 (insbes. ein sogen. Druckband 3) ist in der Relativlage zum Förderband 2 einstellbar - und dementsprechend höhenverstellbar angeord¬ net - sowie als Ganzes abgefedert gehaltert.The pressing device 3 (in particular a so-called pressure belt 3) can be adjusted in the position relative to the conveyor belt 2 - and is accordingly arranged in a height-adjustable manner - and is supported in a spring-loaded manner.
In bevorzugter Weise sind Förderband 2 und Andrück- oder Niederhaltereinrich¬ tung 3 jeweils als komplette "Montageeinheit" lösbar am Maschinengestell 1 oder einem demselben zugeordneten Teil, insbesondere Halter 11 , angeordnet. Diese Montageeinheiten sind in Fig. 1 mittels Kreuzschraffur gekennzeichnet. Sie wei¬ sen dabei Elemente 15, 16, 17 einer Steckverbindung, nämlich solche zur Justie- rung/Lage-fixierung (Position 15), Arretiermittel 16 (z.B. Schrauben) sowie eine Elektrokupplung 17 auf. Bei einer Maschinen-Ausbildung mit einer solchen Fördereinrichtung 2 und An- drückeinrichtung 3 ist die Stillstandszeit bei anfallender Wartungs- und/oder Reparaturarbeit auf ein Minimum reduzierbar, wenn die in der Maschine vorhan¬ dene^) Einrichtung(en) 2/3 demontiert und durch eine Ersatzeinheit ersetzt wird. In a preferred manner, conveyor belt 2 and pressing or holding-down device 3 are each detachably arranged as a complete “assembly unit” on the machine frame 1 or a part associated with it, in particular holder 11. These assembly units are marked in FIG. 1 by means of cross hatching. They have elements 15, 16, 17 of a plug connection, namely those for adjustment / position fixing (position 15), locking means 16 (eg screws) and an electric coupling 17. In the case of a machine design with such a conveying device 2 and pressing device 3, the downtime in the event of maintenance and / or repair work can be reduced to a minimum if the device (s) 2/3 present in the machine are dismantled and is replaced by a replacement unit.
