Abstract

The cutting device has two cutter components. It is especially suitable for split plain tiles. The cutter carriers (25) may be pivoted into their inoperative and operative positions. Each cutter (25) is connected to a spindle (29, 30), the spindles being arranged coaxially (40) one within the other. Thus the cutter carriers pivot about the same axis (40) at the same time in the manner of scissors. The cutter carriers (25) are forked and the cutters (26) are in the form of wires and interchangeable. This cutting device is permanently installed on the extruding press belt. It is nevertheless easy to regulate, can be monitored and operates reliably.

Description

Schneidvorrichtung mit mindestens zwei Schneidelemen¬ ten Cutting device with at least two cutting elements
Die vorliegende Erfindung betrifft eine Schneidvor¬ richtung mit mindestens zwei Schneidelementen, insbe¬ sondere zum Nasenschneiden von Spalt-Biber-Ziegeln.The present invention relates to a cutting device with at least two cutting elements, in particular for the nose cutting of split beaver bricks.
Es ist bekannt, dass sog. Strangdachziegel von einer Strangpresse als flachliegender, kontinuierlich aus¬ tretender Strang erzeugt werden, wobei die sog. Spalt-Biber-Ziegel mindestens eine sog. Nase aufwei¬ sen, welche dazu dient, den Ziegel an der Dachkon¬ struktion festzuhalten.It is known that so-called extruded roof tiles are produced by an extrusion press as a flat, continuously emerging strand, the so-called split beaver tiles having at least one so-called nose, which is used to hold the tile on the roof cone to hold on to the structure.
Im Gegensatz zu der normalen, ausgesprochen dreidi¬ mensionalen Form von Ziegeln sind die Dachziegel in einer Dimension degeneriert. Sie bilden daher flache, praktisch als zweidimensionale Gebilde zu behandelnde Elemente. Deren Behandlung bringt eine wesentliche Anzahl von Nachteilen mit sich, da sie nicht auf die gleiche Weise gefertigt werden können wie die dreidi¬ mensionalen Ziegel.In contrast to the normal, extremely three-dimensional shape of tiles, the roof tiles are degenerate in one dimension. They therefore form flat elements that can be treated practically as two-dimensional structures. Their treatment entails a substantial number of disadvantages, since they cannot be manufactured in the same way as the three-dimensional bricks.
Es ist nun bekannt geworden, auch bei der Dachziegel- herstell'ung schon am Austritt der Strangpresse drei¬ dimensionale Gebilde zu erzeugen, indem das Mundstück der Strangpresse so ausgebildet wurde, dass die bei¬ den Seitenwände des dreidimensionalen Körpers als einander mit ihren Unterseiten zugekehrte Spalt-Bi¬ ber-Ziegel erscheinen. Diese Ziegel weisen einander gegenüberliegende Nasenstränge auf. Sie sind durch mehrere Querstege miteinander verbunden. Ein derart geformter Press-Strang wird dann auf übli¬ che Weise quer durchgetrennt und die entstehenden körperlichen Gebilde mit den zwei untereinander ver¬ bundenen Spalt-Biber-Ziegel-Rohlingen wie normale Ziegelrohlinge weiterbehandelt. Dabei ist aber darauf zu achten, dass die einander jeweils zugekehrten Na¬ senstränge bis auf die verbleibenden Haltenasen von der Unterseite des Ziegels entfernt werden müssen, wie dies auch bei der bisherigen Herstellung einzel¬ ner Dachziegel bekannt geworden ist.It has now become known to produce three-dimensional structures at the outlet of the extrusion press, even in the manufacture of roof tiles, by designing the extrusion press mouthpiece in such a way that the two side walls of the three-dimensional body face one another with their undersides Gap-Bi-ber bricks appear. These bricks have opposite nasal strands. They are connected to each other by several crossbars. A press strand shaped in this way is then cut transversely in the usual way and the resulting physical structures with the two interconnected split beaver brick blanks are further treated like normal brick blanks. However, care must be taken to ensure that the respective wet strands facing each other, apart from the remaining retaining lugs, must be removed from the underside of the tile, as has become known in the previous production of individual roof tiles.
Zur teilweisen Entfernung derartiger Nasenstränge kennt man Schneidvorrichtungen, welche jedoch die folgenden Punkte nicht berücksichtigen: Sofern die Schneidvorrichtung am Mundstück der Strangpresse selbst angeordnet ist, ist eine Ueberwachung der Tä¬ tigkeit der Schneidvorrichtung praktisch ausgeschlos¬ sen. So kann beispielsweise nicht geprüft werden, ob die Nasen genau eingekerbt werden.Cutting devices are known for the partial removal of such nasal strands, but they do not take the following points into account: if the cutting device is arranged on the die of the extrusion press itself, monitoring of the activity of the cutting device is practically excluded. For example, it cannot be checked whether the noses are notched exactly.
Es ist auch bekannt, die sich, gegenüberliegenden Na¬ senstränge durch einen Verbindungssteg zu verbinden, was beim Abschneiden des Nasenstranges auf einem Teil seiner Länge zu Schwierigkeiten führen kann, insbe¬ sondere aber beim Auεeinanderbrechen des Gebildes zum Erhalt der beiden Ziegel.It is also known to connect the opposing strands of water by means of a connecting web, which can lead to difficulties when cutting off the nose strand over part of its length, but in particular when the structure breaks apart to maintain the two bricks.
Es ist ferner schwierig, den Abfall der Nasen unver¬ züglich zu entfernen, so dass sie unnötig mitgebrannt und getrocknet werden.It is also difficult to remove the waste of the noses immediately, so that they are burned and dried unnecessarily.
Die vorliegende Erfindung bezweckt die Schaffung ei¬ ner Schneidvorrichtung, welche als Festteil an der Strangpressstrasse angeordnet ist und trotzdem leicht einstellbar, überwachbar und sicher arbeitet.The present invention aims to provide a cutting device which is a fixed part of the Extrusion line is arranged and yet easy to adjust, monitor and work safely.
Eine derartige Schneidvorrichtung ist gekennzeichnet durch einen der Ansprüche.Such a cutting device is characterized by one of the claims.
Die Erfindung wird anschliessend beispielsweise an¬ hand einer Zeichnung erläutert.The invention is subsequently explained, for example, using a drawing.

Fig. 7 einen Ausschnitt aus dem Uebergangsbereich der Betätigungswellen mit der einen Schneidgabel.Fig. 7 shows a section of the transition region of the actuating shafts with the one cutting fork.
Fig. 1 zeigt die Vorderansicht eines Dachziegel-Dop- pelstranges 1, der bekannterweise durch bekannte Schneidvorrichtungen in entsprechende Ziegεlrohlinge quergeschnitten wird. Die Seiten eines derartigen Ziegelrohlings werden durch zwei mit ihren Grundflä¬ chen sich gegenüberliegenden Spalt-Biber-Ziegeln 2 und 3 gebildet, deren schmale Breitseiten 5 und 6 er¬ sichtlich sind. Die beiden Ziegel 2 und 3 sind durch Verbindungsstege 8 verbunden. An der Uebergangsstelle der Stege 8 in die Ziegel 2 und 3 sind Bruchkerben 9 vorgesehen, welche nach dem Brennen ein Trennen der Spalt-Biber-Ziegel 2 und 3 von den Stegen 8 ermögli¬ chen. Um die Ziegel auf Dachlatten festzuhalten, sind sie normalerweise mit einer oder zwei Nasen versehen. Bei der Herstellung werden diese sich vom Breitsei¬ tenende nach der vorderen Abrundungsseite hin er¬ streckenden Nasen in dem Sinne gebildet, dass die sich über die ganze Ziegellänge erstreckenden Nasen¬ stränge 11 und 12 bis auf die verbleibenden Nasen von der Unterseite des Ziegelrohlings getrennt werden. Dazu bedarf es einer Schneidvorrichtung, welche im vorliegenden Falle in Fig. 1 als Schneidvorrichtung 14 bzw. als Schneidvorrichtung 15 ersichtlich ist. Jede der beiden Schneidvorrichtungen 14 und 15 ist als Doppel-Schneidvorrichtung ausgebildet, da jede einen der beiden Nasenεtränge 11 und 12 durchschnei- den und abtrennen muss.FIG. 1 shows the front view of a double-strand roof tile 1 which is known to be cross-cut into corresponding brick blanks by known cutting devices. The sides of such a brick blank are formed by two split beaver bricks 2 and 3 with their base surfaces opposite one another, the narrow broad sides 5 and 6 of which can be seen. The two bricks 2 and 3 are connected by connecting webs 8. At the transition point of the webs 8 into the bricks 2 and 3, notches 9 are provided which, after firing, enable the split beaver bricks 2 and 3 to be separated from the webs 8. In order to hold the tiles on roof battens, they are usually provided with one or two noses. During manufacture, these lugs extending from the broad end towards the front rounding side are formed in the sense that the nose strands 11 and 12, which extend over the entire length of the brick, are separated from the underside of the brick blank except for the remaining lugs . This requires a cutting device, which in the present case can be seen in FIG. 1 as a cutting device 14 or as a cutting device 15. Each of the two cutting devices 14 and 15 is designed as a double cutting device, since each of the two nose strands 11 and 12 cuts through that and separate.
In Fig. 1 ist in gestrichelter Darstellung die linke und rechte Schneidgabel offen, d.h. in Schneidlage ersichtlich, während sie mit vollem Strich in ge¬ schlossener Lage 18 erscheint.In Fig. 1, the left and right cutting fork is open in dashed lines, i.e. visible in the cutting position, while it appears in full position in the closed position 18.
Die Betätigung der Schneidgabeln erfolgt mittels ei¬ nes Antriebes 20 bzw. 21, welche Antriebe normaler¬ weise als pneumatisch betätigte Zylinder/Kolbenaggre¬ gate ausgebildet sind.The cutting forks are actuated by means of a drive 20 or 21, which drives are normally designed as pneumatically actuated cylinders / piston assemblies.
In Fig. 2 ist die Schneidvorrichtung in Seitenansicht dargestellt. Es ist die eine Schneidgabel 25 mit ei¬ nem Schneiddraht 26 ersichtlich, welcher in zwei Drahthaltern 27 eingespannt ist. Dem Antrieb der bei¬ den Schneidgabeln 25 dient einerseits eine Hohlwelle 29, an welcher die eine Schneidgabel 25 und ander¬ seits eine Innenwelle 30 mit einem Kopf 31, an dem die andere Schneidgabel 25 mittels je einer Schweis- εung 32 befestigt ist. Die in der Hohlwelle 29 stek¬ kende Innenwelle 30 und die Hohlwelle 29 selbst sind als Einheit in einem Schwenkwellenlager 33 gelagert. Das Schwenken der beiden Wellen 29 und 30 in gegen¬ läufigem Drehsinn erfolgt mittels eines Schwenkge¬ stängevierecks 37, das bezüglich einer Längsverschie- beachse 38 im Sinne der Fig. 3 die Schneidgabeln in ihre Oeffnungslage schwenkt bzw. gemäss Fig. 5 in ih¬ re Schliesslage, wie dies- die Fig. 4 und 6 erkennen lassen. Die einzelnen Hebel des Schwenkgestängevier- ecks 37 sind über Kugelgelenke 39 miteinander verbun¬ den. Die Schwenkachse der beiden Wellen 29 und 30 ist mit 40 bezeichnet. Ueber ein Joch 41 ist das Schwenk- gestängeviereck 37 mit einer Kolbenstange 44 eines Kolbens in einem Pneumatikzylinder 43 verbunden, wo¬ bei in ausgefahrenem Zustand des Kolbens gemäss Fig. 3 die Schneidvorrichtung sich in ihrer Schneidlage gemäss Fig. 4 befindet. Wenn sich der Dachziegel-Dop¬ pelstrang 1 in Pfeilrichtung gemäss Fig. 4 bewegt, so trennen die Schneiddrähte 26 der Schneidgabeln 25 die Nasenεtränge 11 und 12 in Längsrichtung vom Ziegel¬ rohling, bis im vorgesehenen Moment die Steuerung auf den Pneumatikzylinder 43 wirkt und dessen Kolben mit der Kolbenstange 44 in die in Fig. 5 dargestellte La¬ ge zieht, wodurch die Schneidvorrichtung durch Zuein¬ anderschwenken der Schneidgabeln 25 aus ihrer Schneidlage geschwenkt wird, um den noch verbleiben¬ den Rest der Nasenstränge 11 und 12 als Nasen 48, 49 stehenzulassen. Durch die Schwenkbewegung wird gleichzeitig der Nasenstrang 11 und 12 quer durch¬ trennt. Die von der Innenfläche der Ziegel 2 und 3 durchtrennten Teile der Nasenεtränge 11 und 12 fallen ab und werden, beispielsweiεe in einem Behälter, ge¬ sammelt. Die Ziegel bewegen sich auf ihrer Bahn wei¬ ter.In Fig. 2 the cutting device is shown in side view. One cutting fork 25 with a cutting wire 26 can be seen, which is clamped in two wire holders 27. The two cutting forks 25 are driven on the one hand by a hollow shaft 29 on which the one cutting fork 25 and on the other hand an inner shaft 30 with a head 31 to which the other cutting fork 25 is fastened by means of a welding 32. The inner shaft 30 which is inserted in the hollow shaft 29 and the hollow shaft 29 itself are mounted as a unit in a swivel shaft bearing 33. The two shafts 29 and 30 are pivoted in the opposite direction of rotation by means of a swivel rod quadrilateral 37 which swivels the cutting forks into their open position with respect to a longitudinal displacement axis 38 in the sense of FIG. 3 or in their opening position according to FIG. 5 Closed position, as can be seen in FIGS. 4 and 6. The individual levers of the swivel linkage quadrilateral 37 are connected to one another via ball joints 39. The pivot axis of the two shafts 29 and 30 is designated 40. About a yoke 41 is the swivel rod square 37 connected to a piston rod 44 of a piston in a pneumatic cylinder 43, the cutting device being in its cutting position according to FIG. 4 when the piston is extended according to FIG. 3. 4, the cutting wires 26 of the cutting forks 25 separate the nose strands 11 and 12 in the longitudinal direction from the blank until the control acts on the pneumatic cylinder 43 and on it 5 pulls the piston with the piston rod 44 into the position shown in FIG. 5, as a result of which the cutting device is pivoted out of its cutting position by pivoting the cutting forks 25 towards one another, around the remainder of the nose strands 11 and 12 as noses 48, 49 let stand. The pivotal movement simultaneously cuts through the nostrils 11 and 12 transversely. The parts of the nose strands 11 and 12 cut through by the inner surface of the bricks 2 and 3 fall off and are collected, for example in a container. The bricks continue to move on their path.
Es iεt möglich, nach dem Wegεchneiden der entspre¬ chenden Teile der Nasenεtränge 11 und 12 das Vorhan¬ densein der verbleibenden Nasen beispielεweiεe op- tiεch zu überwachen.It is possible, after the corresponding parts of the nose strands 11 and 12 have been cut away, to optically monitor the presence of the remaining noses, for example.
Der geεchilderte Antrieb der Schneidgabeln iεt εehr einfach, da dieεe durch eine gegenläufige Bewegung der Wellen 29 und 30 in eine geschlossene bzw. geöff¬ nete Lage versetzt werden. Die Schneidvorrichtung ist im übrigen, im Gegensatz zu den hin- und herbewegten Strangschneidern, als Festteil vorgesehen, so dass auch die bei Bewegungen solcher Bearbeitungsteile auftretenden Schwierigkeiten vermieden sind.The described drive of the cutting forks is very simple, since they are moved into a closed or open position by an opposite movement of the shafts 29 and 30. The cutting device is otherwise, in contrast to the reciprocating Strand cutters, provided as a fixed part, so that the difficulties encountered when moving such machining parts are avoided.
Da der Dachziegel-Doppelstrang 1 nach dem Austreten aus der Strangpresse weich verformbar ist, kann den Schneidgabeln 25 mit den Schneiddrähten 26 ein Füh¬ rungskeil vorgelagert sein, welcher die entsprechen¬ den Abstände sichert und damit εicherεtellt, daεε die Abtrennung der Nasenstränge 11 und 12 an den Rückflä¬ chen der Ziegel erfolgt und nicht über diesen oder in diesen.Since the roof tile double strand 1 is softly deformable after exiting the extrusion press, the cutting forks 25 with the cutting wires 26 can be preceded by a guide wedge, which secures the corresponding distances and thus ensures that the separation of the nose strands 11 and 12 takes place on the back surfaces of the bricks and not above or in them.
Es iεt grundsätzlich möglich, die Schneiddrähte 26 beim Schneiden in Stosεlage, wie Fig. 4 zeigt, zu verwenden oder in Gegenrichtung in Ziehlage.In principle, it is possible to use the cutting wires 26 when cutting in the pushed position, as shown in FIG. 4, or in the opposite direction in the pulled position.
Eε εind εelbstverεtändlich alle bewegten Teile ein- εtellbar, auch die Gabelöffnung der Schneidgabeln 25, indem die Schwenklage der Welle 29 gegenüber den Klemmköpfen 46 der entεprechenden Schwenklaschen des Schwenkgestängevierecks 37 relativ zueinander ver¬ stellt werden. Grundsätzlich kann auch die Hubhöhe oder Länge der Kolbenstange 44 in ein- und ausgefah¬ renem Zustand verändert werden sowie die relative La¬ ge der beiden Schneidgabeln 25 zueinander.Of course, all moving parts can be adjusted, including the fork opening of the cutting forks 25, by adjusting the pivot position of the shaft 29 relative to one another relative to the clamping heads 46 of the corresponding pivot tabs of the pivot linkage rectangle 37. In principle, the lifting height or length of the piston rod 44 can also be changed in the retracted and extended state, and the relative position of the two cutting forks 25 to one another.
Die beschriebene Schneidvorrichtung ermöglicht hier¬ mit auf einfache und sichere Weise das Herstellen der Aufhängenasen bei Dachziegel-Doppelsträngen.The cutting device described hereby enables the hanging lugs in double-strand roof tiles to be produced in a simple and safe manner.
