Description

Fliesenschneider  tile cutter
Die Erfindung betrifft einen Fliesenschneider mit einem Gestell mit einer Bodenplatte und einer oberhalb der Bodenplatte angeordneten Führung, entlang welcher ein Schneidwerkzeug tragender Schlitten verlagerbar ist, um auf der Oberfläche einer auf der Bodenplatte aufliegenden Fliese eine Kerbe zu erzeugen, und mit einer mit dem Schlitten getriebegekoppelten Brechbackeneinrichtung, die in der Endphase der Verlagerung des Schlittens auf die Oberfläche der Fliese abgesenkt wird, um die Fliese entlang der Kerbe zu brechen. The invention relates to a tile cutter comprising a frame having a base plate and a guide arranged above the base plate, along which a carriage carrying a cutting tool is displaceable in order to create a notch on the surface of a tile resting on the base plate, and a gearbox coupled to the carriage Crushing jaw means, which is lowered in the final phase of the displacement of the carriage on the surface of the tile to break the tile along the notch.
Die GB 932,640 bzw. die DE 12 35 792 beschreibt einen Fliesenschneider mit einer Bodenplatte und einer oberhalb der Bodenplatte angeordneten Führung, entlang welcher ein Schlitten verlagerbar ist, der ein als Schneidrad ausgebildetes Schneidwerkzeug trägt. Mittels eines Lenkers ist der Schlitten an einem orts- fest am Gestell schwenkbar angeordneten Hebel verbunden. Wird der Hebel verschwenkt, so gleitet der Schlitten entlang der Führung. In einer auf der Bodenplatte aufliegende Fliese wird eine Kerbe eingeschnitten. In der Endphase des Verschwenkens des Hebels wird eine Brechbackeneinrichtung abgesenkt, die eine Hebelanordnung aufweist, die schwenkbar am Gestell befestigt ist. Am Ende der Hebelanordnung sitzen zwei Brechbacken, die jeweils auf einer Seite der Kerbe von oben auf die Oberfläche der Fliese drücken, um sie entlang der Kerbe zu brechen. GB 932,640 and DE 12 35 792 describes a tile cutter with a bottom plate and a guide arranged above the bottom plate, along which a carriage is displaceable, which carries a cutting tool designed as a cutting tool. By means of a link, the carriage is connected to a lever which is pivotally arranged on the frame in a stationary manner. When the lever is pivoted, the carriage slides along the guide. In a lying on the bottom plate tile a notch is cut. In the final phase of pivoting of the lever, a crushing jaw means is lowered having a lever arrangement which is pivotally mounted on the frame. At the end of the lever assembly are two crushing jaws, each pressing on one side of the notch from above onto the surface of the tile to break it along the notch.
Die DE 10 2012 101 773 AI beschreibt einen Fliesenschneider, bei dem die Brechbackeneinrichtung am Schlitten befestigt ist. Durch Verschwenken eines am Schlitten befestigten Hebels wird die Brechbackeneinrichtung abgesenkt, um die zuvor mit einer Kerbe versehene Fliese entlang der Kerbe zu brechen. Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Fliesenschneider gebrauchsvorteilhaft weiterzubilden. Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung. Zunächst und im Wesentlichen wird vorgeschlagen, dass die Brechbackeneinrichtung und der Schlitten über eine Steuerflankenanordnung zusammenwirken. Die Steuerflankenanordnung weist bevorzugt eine Steuerflanke auf. Diese Steuerflanke wirkt mit einem Steuerglied des Schlittens zusammen, um die Brechbackeneinrichtung abzusenken. In einer bevorzugten Weiterbildung der Erfindung wird die Steuerflanke von einer Steuerschräge gebildet. Diese Steuerschräge wird bevorzugt von der Brechbackeneinrichtung ausgebildet. Entlang der Steuerschräge kann das bevorzugt dem Schlitten zugeordnete Steuerglied gleiten, um die Brechbackeneinrichtung abzusenken. Es ist aber auch denkbar, die Steuerschräge dem Schlitten und das Steuerglied der Brechbackeneinrich- tung zuzuordnen. Bevorzugt wird das Steuerglied von einem Rollenpaar ausgebildet. Die Brechbackeneinrichtung kann zwei im Wesentlichen lediglich quer zur Verlagerung des Schlittens bewegbar am Gestell befestigte Brechbacken aufweisen. Jede der beiden Brechbacken kann eine Steuerflanke, also insbesondere eine Steuerschräge aufweisen. Die Hebelanordnung ist derart am Gestell befestigt, dass das Steuerglied die Steuerflanke erst dann beaufschlagt, wenn mit dem Schneidwerkzeug bereits eine vollständige Kerbe in die Oberfläche der Fliese eingebracht worden ist. Die Brechbacken können hierzu an einer schwenkbar am Gestell befestigten Hebelanordnung sitzen, wobei die Hebelanordnung zwei parallel zueinander verlaufende Hebelarme aufweisen können. Die beiden Hebelarme sind um eine Schwenkachse schwenkbar, insbesondere an einem Träger der Führung befestigt. An den freien Enden der Hebelarme sitzen jeweils insbesondere keilförmige Brechbacken. Auf der zur Führung weisenden, schräg verlaufenden Oberseite der Brechbacken kann jeweils eine Rolle entlang rollen, um die Brechbacke abzusenken, so dass ihre Unterseite eine Brechkraft gegen die Oberfläche der zu brechenden Fliese entfalten kann. Zwi- sehen den beiden Brechbacken kann sich ein Spalt befinden, durch den das Schneidwerkzeug hindurchtreten kann. Um sicherzustellen, dass die Absenkbewegung der Brechbacken erst dann erfolgt, wenn die Kerbe vollständig in die Oberfläche der Fliese eingebracht worden ist, ist das Schneidwerkzeug bezogen auf die Schnittrichtung des Schlittens dem Steuerglied vorgeordnet. Erst wenn das Schneidwerkzeug vollständig durch den Schlitz hindurchgetreten ist, tritt das Steuerglied gegen die Steuerflanke. In einer Weiterbildung der Erfindung ist vorgesehen, dass die Länge der Hebelanordnung verstellbar ist. Dies hat zur Folge, dass der Abstand der Brechbacken gegenüber einem Anschlag, gegen den die zu schneidende Fliese angelegt werden kann, verstellbar ist. Insbesondere zum Schneiden von Diagonalschnitten erweist es sich als vorteilhaft, wenn die Lage der Brechbacken entlang der Führung verstellbar ist. Die Führung wird vorzugsweise von zwei parallel zueinander verlaufenden Schienen ausgebildet. Die Schienen erstrecken sich gleich beabstandet, also in einer parallelen Erstreckung gegenüber der Bodenplatte. Aus der Bodenplatte kann eine Brechrippe in Richtung auf die Führung ragen, die in Verlagerungsrichtung unterhalb des Schneidwerkzeuges verläuft, so dass die beiden Brechbacken jeweils auf einer Seite der Rippe angeordnet sind. Jede Brechbacke kann an einem ihr zugeordneten Hebelarm sitzen. Die beiden Hebelarme können mit einer Quer- stange miteinander verbunden sein. Es können zwei Querstangen vorgesehen sein, die parallel zueinander verlaufende Hebelarme miteinander verbinden. Die Hebelarme können aus Stahl bestehen und insbesondere von Stanzteilen gefertigt sein. Zur Längenvariation können die beiden Hebelarme jeweils einen Längsschlitz mit quer davon abragenden Rastmulden aufweisen. In die Rast- mulden kann ein Abschnitt der Schwenkachse Aufnahme finden, so dass der Abstand der Brechbacken von der Schwenkachse einstellbar ist. DE 10 2012 101 773 AI describes a tile cutter, wherein the crushing jaw means is attached to the carriage. By pivoting a lever mounted on the carriage, the crushing jaw means is lowered to break the previously notched tile along the notch. The invention has for its object to further develop the generic tile cutter nutzsvorteilhaft. The object is achieved by the invention specified in the claims. First and foremost, it is proposed that the crushing jaw device and the slide interact via a control flank arrangement. The control edge arrangement preferably has a control edge. This control edge cooperates with a control member of the carriage to lower the crushing jaw assembly. In a preferred embodiment of the invention, the control edge is formed by a control slope. This control slope is preferably formed by the crushing jaw device. Along the control slope, the preferably associated with the carriage control member slide to lower the crushing jaw means. However, it is also conceivable to assign the control bevel to the carriage and the control member of the crushing jaw device. Preferably, the control member is formed by a pair of rollers. The crushing jaw device can have two crushing jaws, which are mounted on the frame so as to be movable essentially only transversely to the displacement of the carriage. Each of the two crushing jaws can have a control flank, that is to say in particular a control bevel. The lever arrangement is fixed to the frame in such a way that the control member only acts on the control flank when a complete notch has already been introduced into the surface of the tile with the cutting tool. For this purpose, the crushing jaws can be seated on a lever arrangement which is pivotably mounted on the frame, wherein the lever arrangement can have two lever arms which run parallel to one another. The two lever arms are pivotable about a pivot axis, in particular attached to a support of the guide. In particular, wedge-shaped crushing jaws each sit at the free ends of the lever arms. On the side facing the guide, obliquely extending top of the crushing jaws can roll along a roll in order to lower the crushing jaw, so that its bottom can develop a refractive power against the surface of the tile to be crushed. be- see the two crushing jaws may be a gap through which the cutting tool can pass. To ensure that the lowering movement of the crushing jaws takes place only when the notch has been completely introduced into the surface of the tile, the cutting tool is upstream of the control member relative to the cutting direction of the carriage. Only when the cutting tool has completely passed through the slot, the control member occurs against the control edge. In a further development of the invention it is provided that the length of the lever arrangement is adjustable. This has the consequence that the distance between the crushing jaws relative to a stop against which the tile to be cut can be applied, is adjustable. In particular, for cutting diagonal cuts, it proves to be advantageous if the position of the crushing jaws along the guide is adjustable. The guide is preferably formed by two mutually parallel rails. The rails extend equally spaced, ie in a parallel extension relative to the bottom plate. From the bottom plate can protrude a crushing rib in the direction of the guide, which extends in the displacement direction below the cutting tool, so that the two crushing jaws are each arranged on one side of the rib. Each crushing jaw can sit on a lever arm assigned to it. The two lever arms can be connected to each other with a crossbar. It can be provided two cross bars, which connect mutually parallel lever arms together. The lever arms may be made of steel and in particular be made of stampings. For length variation, the two lever arms may each have a longitudinal slot with transversely projecting locking recesses. A section of the pivot axis can be accommodated in the latching troughs so that the distance of the crushing jaws from the pivot axis can be adjusted.

The carriage 4 has a housing with a downwardly projecting cutting tool 5, which is designed as a cutting wheel.
An der Bodenplatte 2 befindet sich ein Kopfanschlag 17, gegen den eine Stirnkante einer zu schneidenden Fliese 27 angelegt werden kann. On the bottom plate 2 is a head stop 17 against which an end edge of a tile 27 to be cut can be applied.
Am Schlitten 4 befinden sich zwei Steuerrollen 9, die bezogen auf die Lage des Anschlags 17 rückwärtig des Schneidwerkzeuges 5 angeordnet sind. Die beiden Rollen 9 sind seitlich und in Schnittrichtung versetzt zum Schneidrad 5 angeordnet und am Ende einer Schwinge 32 befestigt, die um eine Achse 33 in einer Höhlung des Gehäuses des Schlittens 4 schwenkbar gelagert ist. Die Schwinge 32 besitzt einen Anschlag 39. Dieser Anschlag wirkt mit der exzentrischen Außenumfangsfläche eines Höheneinstellrades 38 zusammen. Das Höheneinstellrad ragt bereichsweise durch eine auf der Gehäuseoberseite an- geordnete Öffnung, so dass es gedreht werden kann. Durch Drehen des Höheneinstellrades 38 wird dessen exzentrische Umfangsfläche in eine andere Position gegenüber dem Anschlag 39 gebracht, so dass der Schwenkwinkel der Schwinge 32 verstellbar ist. Hierdurch kann die Höhenlage des Steuergliedes 9 eingestellt werden und an verschieden dicke Fliesen angepasst werden. On slide 4 are two control rollers 9, which are arranged relative to the position of the stop 17 rearward of the cutting tool 5. The two rollers 9 are arranged laterally and in the cutting direction offset from the cutting wheel 5 and secured to the end of a rocker 32 which is pivotally mounted about an axis 33 in a cavity of the housing of the carriage 4. The rocker 32 has a stop 39. This stop cooperates with the eccentric outer peripheral surface of a Höheneinstellrades 38. The height adjustment wheel projects in regions through an opening arranged on the upper side of the housing, so that it can be turned. By turning the Höheneinstellrades 38 whose eccentric peripheral surface is brought into a different position relative to the stop 39, so that the pivot angle of the rocker 32 is adjustable. In this way, the altitude of the control member 9 can be adjusted and adapted to different thickness tiles.
Entlang der Bodenplatte 2 verläuft in Erstreckungsrichtung der beiden Führungsschienen 3 eine Brechrippe 25. Die Brechrippe 25 verläuft unterhalb des Schneidrades 5 und wird von einem T-f örmigen Körper gebildet, der an der Tragplatte 14 befestigt ist. Along the bottom plate 2 extending in the extension direction of the two guide rails 3 a crushing rib 25. The crushing rib 25 extends below the cutting wheel 5 and is formed by a T-shaped body which is fixed to the support plate 14.
Mittels eines Stellrades 24 kann die Vorspannung einer Feder 30 eingestellt werden, die mit einem Ende einen Halteschaft 31 beaufschlagt, an dessen Ende das Schneidwerkzeug 5 sitzt. Das andere Ende der Feder stützt sich an einem Stößel 36 ab, dessen axiale Lage mittels des Stellrades 24 eingestellt werden kann. By means of a setting wheel 24, the bias of a spring 30 can be adjusted, which acts on one end of a support shaft 31, at the end of the cutting tool 5 is seated. The other end of the spring is supported on a plunger 36 whose axial position can be adjusted by means of the adjusting wheel 24.
Es ist ein Höheneinstellring 35 vorgesehen, der eine Innengewindehülse 34 ausbildet. In dem Innengewinde der Hülse 34 steckt ein Gewindeschaft 29. Durch Verdrehen des Höheneinstellrings 35 lässt sich der Gewindeschaft 29 in Achsrichtung verlagern, um so die Höhenlage des Schneidwerkzeuges 5 einzustellen. Mit einem Raststift 37 wird die Drehstellung des Höheneinstellrings 35 bzw. der axial fest im Gehäuse des Schlittens 4 gelagerten Gewindehülse 34 gesichert. It is a Höheneinstellring 35 is provided which forms an internally threaded sleeve 34. By inserting the height adjusting ring 35, the threaded shaft 29 can be displaced in the axial direction so as to adjust the height position of the cutting tool 5. With a locking pin 37, the rotational position of the Höheneinstellrings 35 and the axially fixed in the housing of the carriage 4 mounted threaded sleeve 34 is secured.
Der dem Kopfanschlag 17 örtlich zugeordnete Träger 13 bildet eine Schwenkachse 12 aus, die eine Brechbackeneinrichtung 6 lagert. Die Brechbackeneinrich- tung 6 besitzt zwei voneinander beabstandete Hebelarme 11, die um die Schwenkachse 12 verschwenkt werden können. Die beiden Hebelarme 11 sind mittels Querstangen 20, 16 derart miteinander verbunden, dass sie parallel zueinander verlaufen. An ihren freien Enden tragen die Hebelarme 11 jeweils eine keilförmige Brechbacken 7. Die Brechbacke 7 besitzen eine zur Bodenplatte 2 weisende Unterseite, mit der sie auf einer zu schneidenden Fliese 27 aufliegen. Die Brechbackeneinrichtung 6 kann um die Schwenkachse 12 schwergängig schwenkbar gelagert sein, so dass sie aufgrund der Lagerreibung in verschiedenen Schwenkstel- lungen verbleiben kann. The head stop 17 locally associated carrier 13 forms a pivot axis 12, which supports a crushing jaw device 6. The crushing jaw device 6 has two spaced-apart lever arms 11, which surround the Swivel axis 12 can be pivoted. The two lever arms 11 are connected to each other by means of transverse rods 20, 16 such that they run parallel to one another. At their free ends, the lever arms 11 each carry a wedge-shaped crushing jaws 7. The crushing jaw 7 have a base plate 2 facing bottom, with which they rest on a tile to be cut 27. The crushing jaw device 6 can be pivotally mounted pivotably about the pivot axis 12, so that it can remain in various pivotal positions due to the bearing friction.
Der Unterseite der Brechbacken 7 liegt eine schräg verlaufende Steuerschräge 8 gegenüber. Die Brachbacken 7 besitzen somit eine Keilform. Auf der Oberfläche jeder der beiden Brechbacken 7 befindet sich zusätzlich eine Rille 21, durch die die Steuerrolle 9 rollen kann. The underside of the crushing jaws 7 is opposite to an inclined control slope 8. The fallowing jaws 7 thus have a wedge shape. On the surface of each of the two crushing jaws 7 is additionally a groove 21 through which the control roller 9 can roll.
Die beiden Brechbacken 7 sind voneinander beabstandet, so dass zwischen den beiden Brechbacken 7 ein Spalt 10 verbleibt. Der Spalt 10 hat eine ausreichende Spaltweite, damit das Schneidrad 5 durch den Spalt 10 hindurchtreten kann. Vom freien Ende des Hebelarmes 11 ragt zudem ein Griff abschnitt 28 ab, mit dem die Brechbackeneinrichtung 6 angehoben werden kann. The two crushing jaws 7 are spaced apart, so that a gap 10 remains between the two crushing jaws 7. The gap 10 has a sufficient gap width so that the cutting wheel 5 can pass through the gap 10. From the free end of the lever arm 11 also protrudes a handle portion 28, with which the crushing jaw means 6 can be raised.
Der Abstand der Brechbacken 7 zum Anschlag 17 bzw. zur Schwenkachse 12 kann verstellt werden. Hierzu besitzt jeder der beiden Hebelarme 11 einen Längsschlitz 19, von dem eine Vielzahl von Rastmulden 18 abragen. Die Rastmulden 18 haben einen verschiedenen Abstand zu den Brechbacken 7. Die Schwenkachse 12 kann wahlweise in eine der vielen Rastmulden 18 gelegt werden, so dass die jeweilige Rastmulde 18 eine Lagermulde ausbildet. Hierdurch variiert der Abstand der Brechbacke 7 gegenüber dem Anschlag 17 bzw. der Schwenkachse 12. Die Querstangen 16, 20 verbinden die beiden Hebelarme 11 derart miteinander, dass ein in der Draufsicht rechteckiger Rahmen entsteht. Im Rahmen steckt der Träger 13, so dass die Brechbackeneinrichtung 6 unverlierbar mit dem Gestell 1 verbunden ist. The distance between the crushing jaws 7 to stop 17 or to the pivot axis 12 can be adjusted. For this purpose, each of the two lever arms 11 has a longitudinal slot 19, protrude from which a plurality of locking recesses 18. The locking recesses 18 have a different distance to the crushing jaws 7. The pivot axis 12 can be placed either in one of the many locking recesses 18, so that the respective detent recess 18 forms a storage tray. As a result, the distance between the crushing jaw 7 relative to the stop 17 and the pivot axis 12 varies. The transverse rods 16, 20 connect the two lever arms 11 with each other such that a rectangular in plan view frame is formed. In the frame of the carrier 13, so that the crushing jaw device 6 is connected captively to the frame 1.
Mit der Bezugsziffer 23 wird ein Seitenanschlag bezeichnet, der quer zur Erstre- ckungsrichtung der Führung 3 verstellbar ist. Die Funktionsweise des Fliesenschneiders ist die folgende: The reference numeral 23 denotes a side stop which is adjustable transversely to the extension direction of the guide 3. The operation of the tile cutter is the following:
Soll eine Fliese rechtwinklig zu einer Randkante geschnitten werden, so wird diese Randkante an den Kopf anschlag 17 angelegt. Die Brechbackeneinrichtung 6 wird in eine derartige Position gebracht, dass die beiden Brechbacken 7 unmittelbar am Anschlag 17 liegen. Die Brechbacken 7 liegen dabei im Bereich der Randkante der zu schneidenden Fliese 27.  If a tile is to be cut at right angles to a marginal edge, this marginal edge is applied to the head stop 17. The crushing jaw device 6 is brought into a position such that the two crushing jaws 7 lie directly on the stop 17. The crushing jaws 7 lie in the region of the peripheral edge of the tile to be cut 27th
Sodann wird der Schlitten 4 von einer Stellung entfernt vom Anschlag 17 auf den Anschlag 17 zu verlagert, wobei das Schneidrad 5 auf einer Randkante der Fliese 27 aufläuft und über die Oberfläche der Fliese 27 laufend dort eine Kerbe einritzt. Erreicht das Schneidwerkzeug 5 die beiden Brechbacken 7, so läuft es durch den Spalt 10 hindurch, bis es über die am Anschlag 17 anliegende Randkante der Fliese hinweggelaufen ist. Etwa zeitgleich damit oder geringfügig verzögert treten die beiden voneinander beabstandeten Rollen 9 jeweils gegen die ihnen zugeordneten Steuerschrägen 8 bzw. in die Rillen 21 ein. Bei einer Weiterverlagerung des Schlittens 4 in Richtung auf den Anschlag 17 werden die Brechbacken nach unten gedrückt, so dass die auf der Brechrippe 25 aufliegende Fliese 27 entlang der Kerbe bricht. Dabei läuft das Steuerglied 9 auf der Steuerflanke 8 der Brechbacke 7 auf. Die Schwinge 32 verschwenkt dabei geringfügig, bis ihr Anschlag 39 an die Exzenterkurve des Höheneinstellrades 38 anschlägt. Mit Hilfe des Höheneinstellrades wird die Höhe der Rolle 9 zuvor in eine derartige Position gebracht, dass die Brechbacken erst dann in Wirkung treten, wenn die Kerbe vollständig gefertigt ist. Then, the carriage 4 is displaced from a position away from the stop 17 on the stop 17, wherein the cutting wheel 5 runs up on a peripheral edge of the tile 27 and scoring over the surface of the tile 27 there running a notch. When the cutting tool 5 reaches the two crushing jaws 7, it passes through the gap 10 until it has passed over the edge of the tile resting against the stop 17. At about the same time or slightly delayed, the two spaced-apart rollers 9 each enter against the control ramps 8 assigned to them or into the grooves 21. In a further displacement of the carriage 4 in the direction of the stop 17, the crushing jaws are pressed down so that the resting on the crushing rib 25 tile 27 breaks along the notch. In this case, the control member 9 runs on the control edge 8 of the crushing jaw 7. The rocker 32 pivots slightly until its stop 39 abuts the Exzenterkurve the Höheneinstellrades 38. With the help of Höheneinstellrades the height of the roller 9 is previously in brought such a position that the crushing jaws only come into effect when the notch is completely made.
Sobald die Schwinge 32 an die Exzenterfläche angestoßen ist, übt die Rolle eine Vertikalkraft nach unten aus, die über die Brechbacke 7 auf die Fliese 27 übertragen wird, die sich auf der Brechrippe 25 abstützt. In der Endphase der Verschiebebewegung (siehe Figur 10) bricht die Fliese 27 entlang der Kerbe. As soon as the rocker 32 is pushed against the eccentric surface, the roller exerts a vertical downward force, which is transmitted via the crushing jaw 7 to the tile 27, which is supported on the crushing rib 25. In the final phase of the sliding movement (see FIG. 10), the tile 27 breaks along the notch.
Soll hingegen ein Diagonalschnitt gefertigt werden, so wird die Fliese entspre- chend auf der Bodenplatte 2 angeordnet (siehe Figuren 11 und 12). Das Schnittende hat jetzt eine Entfernung vom Anschlag 17. Die Brechbackeneinrichtung 6 wird deshalb in eine andere Betriebsstellung gebracht, in der die Backen 7 einen Abstand zum Anschlag 17 besitzen, der so gewählt ist, dass die Steuerrollen 9 erst dann eine Brechkraft auf die Brechbacken 7 ausüben, wenn das Schneid- Werkzeug 5 die Kerbe vollendet hat, also die zum Anschlag 17 weisende Randkante der Fliese 27 überlaufen hat. If, on the other hand, a diagonal cut is to be made, then the tile is correspondingly arranged on the bottom plate 2 (see FIGS. 11 and 12). The cutting end now has a distance from the stop 17. The crushing jaw device 6 is therefore brought into a different operating position in which the jaws 7 have a distance from the stop 17, which is selected so that the control rollers 9 only then a refractive power to the crushing jaws. 7 exercise when the cutting tool 5 has completed the notch, so has overflowed to the stop 17 facing edge of the tile 27.
