Abstract

The grinding process is applied to dried or fired wall tile blanks (1). Groups of blanks lying alongside each other are simultaneously flat-ground, using several cutting disks (5) with radial cutting and grinding capacity, mounted on a cutting disk shaft (6). During grinding, the blank group may be fixed and the disks moved, or vice versa.

Description

Die Erfindung bezieht sich auf die Herstellung von plangeschliffenen Ziegeln, insbesondere Mauerziegeln.The invention relates to the production of plane-ground bricks, especially masonry bricks.

Nach dem Stand der Technik werden Mauerziegel in Schleif­ maschinen auf ihren Lagerfugenseiten auf das Endmaß ge­ schliffen. Dabei werden die Formlinge im getrockneten, meist aber im gebrannten Zustand zwischen rotierenden, topfartigen Schleifscheiben hindurchgeführt, mittels Kettenförderer, welche die Formlinge von unten und oben dazwischen einklemmen. Die Antriebsleistung solcher Schleifeinrichtungen übersteigt oft 100 kW. Infolge Abriebes an den Schleifscheiben müssen diese mit komplizierten Meßeinrichtungen überwacht und nachgestellt werden, um ein einigermaßen zuverlässig genaues Formlingsendmaß sicherzustellen. Die Schleifmaschinen sind daher aufwendig und in der Leistung begrenzt, da die Formlinge nur einzeilig durch die Schleifmaschinen geführt werden. According to the state of the art, bricks are sanded machines on their bearing joint sides to the final dimension grind. The moldings are dried, mostly but in the fired state between rotating, pot-like Grinding wheels passed through, by chain conveyor, which clamp the moldings in between from below and above. The drive power of such grinding devices exceeds often 100 kW. As a result of abrasion on the grinding wheels this is monitored with complicated measuring devices and be adjusted to a reasonably reliable accurate Ensure the finished gauge block. The grinders are therefore expensive and limited in performance because the Moldings are only guided through the grinding machines in one line become.  

Als Nachteil erweist sich auch, daß bei geringeren Ziegel­ festigkeiten infolge des erheblichen Schleifdruckes leicht Ecken und Ränder derselben ausbrechen oder verletzt werden. Als Nachteil wird der Verschleiß an den beweglichen Teilen, insbesondere den Ketten empfunden, durch den vielen ent­ stehenden Schleifstaub unterhalb der Schleifebene.Another disadvantage is that with smaller bricks strengths slightly due to the considerable grinding pressure Break out corners and edges of them or get injured. The disadvantage of wear on the moving parts, especially felt the chains through which many ent standing grinding dust below the grinding level.

Aufgabe der Erfindung ist es, eine Schleifvorrichtung für getrocknete und gebrannte Ziegel, insbesondere Ziegel für aufgehendes Mauerwerk anzugeben, bei der vorgenannte Nachteile beseitigt oder mindestens vermindert werden. Die Schleifvorrichtung soll im Bauaufwand gleichfalls geringer ausfallen, und zuverlässigere Ziegelendmaße liefern.The object of the invention is to provide a grinding device for dried and fired bricks, especially bricks for Specify rising masonry at the aforementioned Disadvantages are eliminated or at least reduced. The grinding device should also work in terms of construction turn out to be smaller, and more reliable gauge blocks deliver.

Die Erfindung wird anhand der beiliegenden Zeichnungen dargelegt, inThe invention will become apparent from the accompanying drawings spelled out in

Es bedeuten:
1 Formlinge
2 Transportbahn
3 untere Spannleisten
4 obere Spannleisten
5 Schneidscheiben
6 Schneidscheibenwelle
7 Masch.-Rahmen
8 Führungsbahn
9 Schneidscheibenantrieb It means:
1 moldings
2 transport track
3 lower tension bars
4 upper tension bars
5 cutting discs
6 cutting disc shaft
7 machine frame
8 guideway
9 cutting disc drive

Gemäß der Neuerung wird vorgeschlagen, mehrere Reihen von Formlingen (1) gleichzeitig plan zu bearbeiten in nebeneinander liegenden Formlingsreihen. Dabei werden dieselben vertikal, vorzugsweise von unten nach oben, eingespannt zwischen unteren Spannleisten (3) und oberen Spannleisten (4).According to the innovation, it is proposed to process several rows of moldings ( 1 ) at the same time flat in adjacent rows of moldings. The same are clamped vertically, preferably from bottom to top, between the lower clamping bars ( 3 ) and the upper clamping bars ( 4 ).

Eine entsprechende Anzahl von auf einer Schneidscheibenwelle (6) angeordneten Schneidscheiben (5) wird auf Führungsbahnen (8) horizontal bewegt unter hoher Drehzahl. Somit erfolgt ein kombinierter Schneid- und Schleifvorgang unter radialer Krafteinwirkung auf die Formlinge, was weniger Kraftaufwand, genauere Bearbeitung und fehlerfreie Planflächen ergibt. Die vorzugsweise mit Industriediamanten radial bestückten Schneidscheiben weisen geringen Verschleiß auf, so daß einfachere Meßeinrichtungen genügen zur Betriebsüberwachung. Die neue Schleifeinrichtung kann auch umgekehrt betrieben werden, mit stationärer Schneidscheibenwelle und horizontal bewegten Formlingsreihen.A corresponding number of cutting disks ( 5 ) arranged on a cutting disk shaft ( 6 ) is moved horizontally on guide tracks ( 8 ) at high speed. This results in a combined cutting and grinding process with radial force on the molded parts, which results in less effort, more precise machining and error-free flat surfaces. The cutting disks, which are preferably fitted with industrial diamonds, have little wear, so that simpler measuring devices are sufficient for monitoring the operation. The new grinding device can also be operated in reverse, with a stationary cutting disc shaft and horizontally moving rows of moldings.

Ein besonderer Vorteil ist, daß bei z. B. 3 Formlingsreihen nur 4 Schneidscheiben (5) benötigt werden, da die mittleren Scheiben im Berührungsbereich der einzelnen Ziegelreihen schneiden und schleifen, und je eine Schneidscheibe zwei Ziegelflächen bearbeitet. Auf einem kräftigen Masch.-Rahmen (7) ist die angetriebene Führungsbahn (8) angeordnet, sowie eine mitlaufende Schneidscheibenwelle mit Lagerung und dem Schneid­ scheibenantrieb (9).A particular advantage is that with z. B. 3 rows of moldings only 4 cutting disks ( 5 ) are required, since the middle disks cut and grind in the contact area of the individual rows of tiles, and one cutting disk processes two tile surfaces. On a strong machine frame ( 7 ) the driven guide track ( 8 ) is arranged, as well as a rotating cutting disc shaft with storage and the cutting disc drive ( 9 ).

Die Transportbahn (2), welche taktweise die Formlinge (1) gruppenweise in die Maschine fördert, und nach beendetem Schleifvorgang herausfördert, kann vorzugsweise aus verschleiß­ armen Drahtseilen oder anderen Fördermitteln bestehen. The transport path ( 2 ), which conveys the moldings ( 1 ) in groups into the machine and conveys them out after the grinding process has ended, can preferably consist of low-wear wire ropes or other conveying means.

Die Darstellung Fig. 1-3 stellt lediglich ein Ausführungs­ beispiel des Erfindungsgedankens dar. Dabei wird eine Gruppe von Formlingen (1) stationär, vertikal von Spannleisten (3) (4) festgespannt, und von den Schneidscheiben (5), welche von "A" nach "B" bewegt werden, plangeschliffen. Die beiden mittleren Schneidscheiben (5) bearbeiten je zwei aneinander liegende Steinseiten, woraus sich halbierter Schleifaufwand ergibt. Die Vorrichtung kann auch umgekehrt mit stationärer Schneidscheibenwelle (6) und bewegter Formlingsgruppe betrieben werden.The representation Fig. 1-3 represents only one embodiment of the inventive concept. A group of moldings ( 1 ) stationary, vertically clamped by clamping bars ( 3 ) ( 4 ), and by the cutting discs ( 5 ), which by "A "moved to" B ", ground flat. The two middle cutting disks ( 5 ) each process two adjacent stone sides, which results in halved grinding effort. The device can also be operated in reverse with a stationary cutting disc shaft ( 6 ) and a moving molding group.
