Abstract
Description
Die Erfindung betrifft ein Verfahren zum gleichzeitigen Abfasen der Querkanten zweier übereinanderliegender Gipskartonplatten.The invention relates to a method for simultaneous chamfering the transverse edges of two plasterboard panels lying one above the other.
Es ist bekannt, daß Gipskartonplatten in einem kontinuierlichen Fertigungsverfahren dadurch hergestellt werden, daß aus einer Kartonbahn bestimmter Breite, deren Ränder hochgebogen sind, eine Wanne gebildet wird, in die fließfähiger Gipsbrei durch eine Kalibrierwalze verteilt wird, der dann durch einen weiteren Karton, den sogenannten Rückseitenkarton, abgedeckt und die hochstehenden Ränder des ersten Kartons, des Ansichtsseitenkartons, über den Rückseitenkarton gefaltet und angeklebt werden. Der so entstandene Gipskartonplattenstrang wird in Stücke geschnitten, die bis zu 400 cm und länger sein können. Die Längsränder dieser Gipskartonplattenstücke werden durch entsprechende seitliche Formstücke zu einer kartonummantelten Kante verformt. Die Querkanten, die durch die Aufteilung des Stranges in einzelne Platten entstehen, sind indessen rechteckig und mehr oder weniger rauh.It is known that plasterboard in a continuous Manufacturing processes are made in that from a Cardboard web of certain width, the edges of which are bent up, a tub is formed into the flowable gypsum pulp a calibration roller is distributed, which is then by a another box, the so-called back box, covered and the raised edges of the first box, the View side boxes, folded over the back box and be glued. The resulting plasterboard strand is cut into pieces that are up to 400 cm and longer can. The longitudinal edges of these plasterboard pieces will be through corresponding side fittings to a cardboard-coated edge deformed. The transverse edges created by the Division of the strand into individual plates are created meanwhile rectangular and more or less rough.
Die Verarbeitung von Gipskartonplatten erfolgt im allgemeinen so, daß man Platten bestimmter Abmessung verarbeitet, die als Ganzes angewendet werden können, beispielsweise geschoßhoch sind, so daß sich nur vertikal stehende Längsrandfugen oder horizontal liegende Längsrandfugen ergeben. In anderen Fällen ist jedoch die Verarbeitung auch von mehreren Gipskartonplatten oder Gipskartonplattenstücken erforderlich, die auch mit den Querkanten aneinander gestoßen und verspachtelt werden müssen. Solche rechtwinkligen Querfugen und Platten mit ausgefransten Kartonrändern lassen sich aber in dieser Art nicht verspachteln, sie müssen für die Verspachtelung vorbereitet werden, das bedeutet, sie müssen mit einer Abfasung versehen werden. Gypsum plasterboard is generally processed so that you can process plates of certain dimensions, which as Whole can be applied, for example floor-to-ceiling are so that there are only vertical longitudinal edge joints or result in horizontal longitudinal edge joints. In other cases is, however, the processing of several plasterboard or plasterboard pieces required, which also with the Cross edges must be butted and filled. Such right-angled transverse joints and panels with frayed Cardboard edges cannot be done in this way fill, they must be prepared for the filler , that means they have to be chamfered become.
Diese Abfasung kann im einfachsten Falle von Hand mit einem Messer oder besser mit einem Hobel hergestellt werden, jedoch ist dies eine langwierige Arbeit und die sich dabei ergebende Abfasung kann, da der Hobel von Hand geführt wird, auch fehlerhaft sein, zumal dann, wenn die Abfasung von einem Laien durchgeführt wird. Kartonplatten, Abfasung, Werkzeuge und Methoden sind in Hanusch, "Gipskartonplatten", 1978, Seite 38 ff. beschrieben.In the simplest case, this chamfer can be done by hand with a Knives or better be made with a planer, however this is a tedious job and the resultant one Chamfering can also, since the planer is guided by hand be faulty, especially if the chamfer by a layperson is carried out. Cardboard plates, chamfer, tools and Methods are in Hanusch, "Gipskartonplatten", 1978, page 38 ff. described.
Die US-A-4 969 380 offenbart eine Vorrichtung und ein Verfahren zur Herstellung einer längerlichen V-förmigen Vertiefung in Gipskartonplatten und nutzt dabei eine Säge mit zwei hintereinanderliegenden Sägeblättern ebenso wie die US-A-3 910 170. Die GB-A-2 006 107 offenbart eine Sägeeinrichtung zum Bearbeiten von Bauholz. Die hier beschriebene Einrichtung ermöglicht das Schneiden des Holzes unter relativ steilem Winkel nach einem Förderband, wenn das Bauholz etwas dünner als der Sägeblattdurchmesser ist und ermöglicht die Benutzung des vollständigen Sägeblattdurchmessers zum Schneiden, wenn das Bauholz relativ dick ist. Die EP-A-0 333 994 offenbart ein Verfahren zum gleichzeitigen Abfasen der Querkanten zweier übereinanderliegender Platten.US-A-4 969 380 discloses an apparatus and method to produce a longer V-shaped recess in Plasterboard and uses a saw with two successive saw blades as well as the US-A-3 910 170. GB-A-2 006 107 discloses a sawing device for processing timber. The facility described here enables the cutting of wood under relatively steep Angle after a conveyor belt if the lumber is slightly thinner than the saw blade diameter is and enables the use of the full blade diameter for cutting if that Lumber is relatively thick. EP-A-0 333 994 discloses a method for chamfering the transverse edges of two at the same time superimposed plates.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zu schaffen, mit der werkseitig, schnell und sauber entsprechende Abfasungen an Querkanten von Gipskartonplatten herstellbar sind.It is therefore an object of the present invention to provide a method to create with the factory, fast and clean corresponding chamfers on the transverse edges of plasterboard are producible.
Gelöst wird diese Aufgabe durch ein Verfahren zum gleichzeitigen Abfasen der Querkanten (17,18) zweier übereinanderliegender Gipskartonplatten in einem Verfahren zur Herstellung von Gipskartonplatten, wobei die Gipskartonplatten (13,14) mit ihren Ansichtsseiten aufeinander liegen und jede Querkante mit jeweils zwei in einem Winkel zueinander stehenden und versetzt angeordnet angetriebenen Kreissägen in Eingriff kommen, wobei jeweils eine Querkante einer Gipskartonplatte mit einer Kreissäge in Eingriff gelangt.This task is solved by a procedure for simultaneous chamfering of the transverse edges (17, 18) of two superimposed plasterboard in a process for Production of plasterboard, the plasterboard (13,14) with their view sides on top of each other and each Cross edge with two each at an angle to each other and staggered driven circular saws into engagement come, each with a transverse edge of a plasterboard a circular saw comes into engagement.
Vorzugsweise erfolgt die Zuführung der mit ihren Ansichtsseiten übereinanderliegenden beiden Gipskartonplatten mittels endloser Transportbänder, die in einem entsprechenden Maschinengestell synchron umlaufend angeordnet sind, während von oben auf die Gipskartonplatte Druck ausgeübt wird. Die Gipskartonplatten liegen dabei auf einem tischartigen Gestell.The view sides are preferably fed in superimposed two plasterboard panels by means of endless Conveyor belts in a corresponding machine frame are arranged in synchronous rotation, while from above on the Plasterboard pressure is exerted. The plasterboard lie on a table-like frame.
Von den beiden Kreissägepaaren, die jeweils wieder aus zwei, einen Winkel miteinander bildenden Kreissägen mit Antrieb bestehen, ist ein Paar quasi ortsfest auf einer Seite des Maschinengestells bzw. der Gipskartonplatten für ihr Querkantenpaar angeordnet, während das gegenüberliegende, wieder aus zwei Kreissägen bestehende Paar, für das andere Querkantenpaar der Gipskartonplatten vorgesehen ist und von diesem weg bewegbar ist, um auf Platten unterschiedlicher Länge eingestellt werden zu können.Of the two pairs of circular saws, each consisting of two, an angle forming circular saws with drive exist, a pair is virtually stationary on one side of the Machine frame or the plasterboard for her Transverse edge pair arranged, while the opposite, again pair consisting of two circular saws, for the other Transverse edge pair of the plasterboard is provided and by this can be moved away on plates of different lengths to be able to be adjusted.
Jedes, aus Kreissäge und Antriebsmotor bestehende Aggregat der Paare ist verschwenkbar, horizontal und vertikal verstellbar, auch das als ortsfest bezeichnete Kreissägepaar. Ortsfest in diesem Zusammenhang soll nur bedeuten, daß beim Übergang auf Platten anderer Länge nur das nicht "ortsfeste" Paar neu eingerichtet zu werden braucht.Each unit consisting of a circular saw and drive motor Pairs can be swiveled, adjusted horizontally and vertically, also the pair of circular saws known as stationary. Festival in this context is only meant to mean that when the transition to Plates of different length only the not "stationary" pair new needs to be set up.
Der Antrieb der Kreissägeblätter erfolgt elektrisch oder pneumatisch oder hydraulisch mit regelbarer Geschwindigkeit. Bei den Kreissägeblättern handelt es sich vorzugsweise um solche mit einer feinen Zahnung oder um mit Diamanten oder Hartmetall besetzte Sägeblätter.The circular saw blades are driven electrically or pneumatically or hydraulically with adjustable speed. The circular saw blades are preferably those with fine teeth or around with diamonds or Carbide-tipped saw blades.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel bildet das Maschinengestell eine große tischartige Aufnahme, auf der wenigstens zwei Gipskartonplattenstapel Aufnahme finden können und zwar mit ihren in der Praxis vorkommenden üblichen Maßen. In the embodiment shown in the drawing the machine frame forms a large table-like holder, find a place on the at least two plasterboard stacks can with their usual in practice Dimensions.
Der Gipskartonplattenstapel besteht in diesem Ausführungsbeispiel aus zwei mit ihren Ansichtsseiten aufeinanderliegenden GKP (GKP = Gipskartonplatten).The plasterboard stack consists of this Embodiment of two with their view sides superimposed GKP (GKP = plasterboard).
Das Maschinengestell ist nach bekannten maschinenbautechnischen Regeln konstruiert und geplant, so daß es seine Aufgabe erfüllen kann.The machine frame is based on known mechanical engineering Rules constructed and planned so that it does its job can meet.
Es besteht aus einem Rahmengerüst, das in seinem oberen Bereich
die tischartige Aufnahme für die GKP bildet z. B. vermittels
Auflageschienen 10, die auch reibungsarm ausgebildet sein
können und die die GKP stabil und sicher tragen.It consists of a framework that is in its upper area
the table-like reception for the GKP forms z. B. mediated
Unterhalb der Ebene, in der die GKP liegen, sind Transporteinrichtungen in From von Ketten oder Bändern 6 und 7 angeordnet, die von unten den GKP-Stapel erfassen.Below are the level in which the GKP are located Transport devices in the form of chains or belts 6 and 7 arranged, which capture the GKP stack from below.
Oberhalb der GKP sind Andruckrollen 8 und 9 vorgesehen, die den GKP-Stapel mit den Transportketten 6 in Eingriff bringen.Pressure rollers 8 and 9 are provided above the GKP Engage the GKP stack with the transport chains 6.
Die Transportkette 6 in der linken Hälfte der Fig. 1 ist über
eine Welle 12 mit der Transportkette 7 in der rechten Hälfte
der Fig. 1 gekuppelt, so daß nur eine Seite angetrieben zu
werden braucht. Die Druckrollen 8, 9 laufen leer und sind in
geeigneter Anzahl vorhanden, obwohl in Fig. 1 nur zwei davon
dargestellt sind. Die Druckrollen sind in einem entsprechend
ausgestalteten Gestell oder Rahmen (nicht dargestellt)
gelagert, der mit Einrichtungen zum Andrücken der Druckrollen
auf die obere 13 der Platten des GKP-Stapels ausgestattet ist.The transport chain 6 in the left half of FIG. 1 is over
a shaft 12 with the transport chain 7 in the
Wird nun die Transporteinrichtung in Gang gesetzt, so erfassen
die Transportketten 6 und 7 die untere Platte 14 des GKP-Stapels

regelbarer Geschwindigkeit z. B. in Richtung des Pfeils 2
bewegbar ist. If the transport device is now started, record it
the transport chains 6 and 7 the
Die oben beschriebenen Einrichtungen wirken nun zur
Verwirklichung der Erfindung mit zwei Paaren 4 und 5 von
Kreissägeaggregaten zusammen, die jeweils wieder aus einem
Antriebsmittel 15 und einem Kreissägeblatt 16 bestehen.The facilities described above are now effective
Realization of the invention with two
Die beiden Kreissägeaggregate eines jeden Paares 4 und 5 bilden
einen Winkel miteinander, der wählbar ist und der der
gewünschten Abfasung entspricht und auch die Dicke der
abzufasenden Platten 13 und 14 angepasst werden kann.Form the two circular saw units of each
Das Antriebsmittel 15 kann elektrischer, pneumatischer oder hydraulischer Art sein. Jeder GKP-Stapel wird nun so von den Transporteinrichtungen auf dem Maschinengestell transportiert, daß die eigentlichen, kartonummantelten Längskanten der GKP rechtwinklig zur Transportrichtung liegen. Die Querkanten der GKP aber parallel zur Transportrichtung und dabei so, daß ihre Querkanten, die linke 17 und rechte 18 nun einen einstellbaren Betrag seitlich über die tischartige Aufnahme hinausragen.The drive means 15 can be electrical, pneumatic or be hydraulic. Each GKP stack is now of the Transport equipment transported on the machine frame, that the actual, cardboard-coated longitudinal edges of the GKP lie at right angles to the direction of transport. The transverse edges of the GKP but parallel to the direction of transport and so that their Transverse edges, the left 17 and right 18 now an adjustable Extend the amount laterally beyond the table-like holder.
Die seitlich über die tischartige Aufnahme des GKP-Stapels
hinausragenden Querkanten 17 und 18 liegen nun im
Eingriffsbereich von je einem Paar Kreissägeaggregaten nämlich
dem Aggregatpaar 4 am linken Seitenrand bzw. dem Aggregatpaar 5
am rechten Seitenrand (Fig. 1 und 2).The side over the table-like holder of the GKP stack
protruding
Wird nun der GKP-Stapel auf dem Maschinengestell vermittels der
Transporteinrichtungen in Bewegung gesetzt und sind die
Aggregatpaare 4 und 5 in entsprechender und richtiger Art auf
die seitlichen Querränder 17 und 18 des GKP-Stapels
ausgerichtet, so werden diese Ränger wie in Fig. 3 abgefast,
wenn die Kreissägeaggregate in Gang gesetzt werden.Now the GKP stack on the machine frame by means of
Transport devices are set in motion and are the
In Fig. 2 ist dieser Abfasungsvorgang kurz vor seinem Ende, da
sich der GKP-Stapel in Richtung des Pfeils 2 bewegt.In Fig. 2 this chamfering process is just before its end, because
the GKP stack moves in the direction of
Aus Fig. 2 ist auch ersichtlich, daß die Kreissägeaggregate im
Abstand zueinander hintereinander versetzt liegen, so daß die
Kreissäge mit dem Antrieb 15' ihre Arbeit schon beendet hat,
während das andere Aggregat 15 um den Betrag der Versetzung
noch arbeiten muß.From Fig. 2 it can also be seen that the circular saw units in
Spaced from each other one behind the other, so that the
Circular saw with the drive 15 'has already finished its work,
while the
Da wie oben beschrieben die Vorrichtung für GKP aller gängigen Längen, die zwischen 250 und 600 cm liegen, vorwendbar sein muß, müssen das Maschinengestell, die Transportvorrichtung, die tischartige Aufnahme und andere Maschinenteile so ausgestaltet sein, daß sie auf diese Längen einstellbar sind.As described above, the device for GKP of all common Lengths between 250 and 600 cm can be used must, the machine frame, the transport device, the table-like holder and other machine parts designed so be that they can be adjusted to these lengths.
In Fig. 1 erfolgt der Antrieb der Transportketten 6 und 7 über
die Welle 12 nur von einer Seite. In einem solchen Falle können
die Welle 12 und andere Teile teleskopierbar oder klappbar
sein. Die tischartige Aufnahme mit den Auflageschienen 10, die
die Andruckrollen 8 und 9 tragenden Einrichtungen könnten
scherenartig ausgeführt und zusammenfahrbar sein und zwar
sowohl von einer Seite als auch von beiden Seiten.In Fig. 1, the transport chains 6 and 7 are driven via
the shaft 12 only from one side. In such a case you can
the shaft 12 and other parts are telescopic or foldable
his. The table-like receptacle with the
Die Anordnung der Kreissägeaggregate 4 und 5 ist in dem
dargestellten Ausführungsbeispiel so getroffen, daß das
Aggregat 4 "ortsfest" ist, während das andere 5 wie der
Doppelpfeil 19 zeigt, auf die GKP zu und von dieser weg
bewegbar ist, weil hier angenommen ist, daß die Anpassung der
Vorrichtung an unterschiedliche GKP-Längen durch
"zusammenschieben" der Vorrichtung nach links erfolgt.The arrangement of the
Beide Kreissägeaggregatpaare, auch das "ortsfeste" Paar 14,
sind universell verstellbar. "Ortsfest" soll hier nur bedeuten,
daß bei Änderung der Länge der GKP nur ein Paar, nämlich das
Paar 5 neu eingerichtet zu werden braucht.Both pairs of circular saw units, also the "stationary"
Wenngleich in dem obigen Beispiel einer Ausbildung der Erfindung das GKP-Paar sich mit seinen Querrändern an den feststehenden Kreissägeaggregatpaaren 4 und 5 vorbei bewegt und abgefast wird, so ist es in kinematischer Umkehrung genauso möglich, das GKP-Paar feststehend anzuordnen und die Kreissägeaggregatpaare 4 und 5 sich über die Länge der Querränder bewegen zu lassen.Although in the above example of training the Invention the GKP pair with its transverse edges on the fixed circular saw unit pairs 4 and 5 moved over and beveled, it is the same in kinematic reversal possible to arrange the GKP pair fixed and the Circular saw unit pairs 4 and 5 over the length of the Let cross edges move.
In Verfolg des Erfindungsgedankens kann sogar der nur nach obiger Beschreibung aus zwei GKP bestehende Stapel zu einen Stapel mit einer ganzzahligen Vielfalt von GKP-Paaren ausgebaut sein z. B. zu einem Stapel von 20 GKP, d. h. zu einem Stapel mit 10 Paaren oder gar mehr.In pursuit of the idea of the invention, even the only one can The above description consists of two GKP stacks of one Expanded stacks with an integer variety of GKP pairs its z. B. to a stack of 20 GKP, d. H. to a stack with 10 pairs or more.
Bei einer solchen erfindungsgemäßen Ausbildung würde der Vielfachstapel festliegen und die Kreissägeaggregatpaare 4 und 5 sich über die Querränder oder Querkanten abfasend bewegen.With such a training according to the invention Multiple stacks are fixed and the circular saw unit pairs 4 and 5 move chamfering across the transverse edges or edges.
Zur rationellen Arbeitsweise könnte dann die Ausbildung weiter so ergänzt werden, daß die Kreissägeaggregatpaare sowohl bei der Hin-Bewegung ein GKP-Paar abfasen und bei der Her-Bewegung das nächste darüber oder darunter liegende Paar.The training could then continue to work rationally are supplemented so that the circular saw unit pairs both at chamfer a pair of GKP during the forward movement and during the forth movement the next pair above or below.
Die Kreissägeaggregatpaare 4 und 5 sind bei dieser
Ausgestaltung in Schienen geführt, haben Antriebsmotor für die
Hin- und Her-Fahrbewegung sowie Einrichtungen, mit denen ein
jedes Paar 4 und 5 nach jeden Gang über die Querkante um den
Betrag der Dicke zweier Platten gehoben oder gesenkt wird, ehe
der nächste Gang beginnt. All diese Vorgänge könnten
programmgesteuert sein. Zur Verringerung der Staubbelästigung
sind die Kreissägeaggregate mit Absaugeinrichtungen versehen.The pairs of
Gemäß einer bevorzugten Ausführungsform der Erfindung wird das Verfahren derart durchgeführt, daß jedem Kreissägeaggregatpaar (4,5) eine Absaugvorrichtung zugeordnet ist. Die Kreissägeblätter (16) sind vorzugsweise fein gezahnt oder mit Diamanten oder Hartmetall besetzt. According to a preferred embodiment of the invention, the Process carried out so that each pair of circular saws (4,5) a suction device is assigned. The Circular saw blades (16) are preferably finely serrated or with Set with diamonds or hard metal.
Es sei nochmals darauf hingewiesen, daß der Winkel, den die
Abfasungen an den beiden übereinanderliegenden Platten
miteinander bilden, dem Winkel entspricht, den die
Kreissägeblätter miteinander bilden. Sie stellen quasi die
Schenkel des Winkels dar und die den Winkel Halbierende 20
liegt in der Ebene, in der sich die aufeinanderliegenden GKP
mit ihren Ansichtsseitenkartons berühren.
Statt des Begriffs "Abfasen" bzw. "Abfasung" ist auch die
Bezeichnung "Anfasen" bzw. "Anfasung" in Gebrauch.It should be pointed out again that the angle that the
Chamfers on the two superimposed plates
form with each other, corresponds to the angle that the
Form circular saw blades together. You basically put them
