Description

Die Erfindung bezieht sich auf eine Schneid- und Verbindungsvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a cutting and connecting device the type mentioned in the preamble of claim 1.

Derartige Schneid- und Verbindungsvorrichtungen werden in großem Umfang insbesondere zum Herstellen von Eckverbindungen zwischen Kunststoffdich­ tungsprofilen verwendet. Hierbei ist es zunächst erforderlich, zwei in einer Einspannvorrichtung eingespannte Profilstrangabschnitte auf Gehrung zuzuschneiden, worauf die Schneidkanten mit einer Konditionseinrichtung in einer Weise behandelt werden, die ein Verbinden der Schnittkanten nach deren Aneinanderbewegen ermöglicht.Such cutting and connecting devices are used on a large scale in particular for making corner connections between plastic seals tion profiles used. It is first necessary to have two in a clamping device clamped profile strand sections on miter cut to what the cutting edges with a conditioning device be treated in a way that is a joining of the cut edges after moving them together enables.

Bei einer bekannten Vorrichtung dieser Art wird eine elektrisch beheiz­ te Messerbaugruppe verwendet, die bei aus Kunststoff bestehenden Profilen diese Profile sowohl durchtrennt als auch die Schnittkanten soweit an­ schmilzt, daß beim nachfolgenden Aneinanderdrücken dieser Schnittkanten eine Verschmelzung und Verbindung der Profilstrangabschnitte herbeige­ führt wird. Hierbei ergibt sich jedoch bei vielen Profilstrangmaterialien das Problem, daß Reste des Profilmaterials an den Messern der Messerbau­ gruppe anhaften, so daß weder ein einwandfreier Schneidvorgang noch ein sauberes Anschmelzen und Verbinden der Schnittkanten möglich ist.In a known device of this type, an electrically heated one te knife assembly used in the case of plastic profiles both cut these profiles and cut edges as far melts that when these cutting edges are pressed together cause a fusion and connection of the extruded sections leads. However, this results in many profile extrusion materials the problem that remnants of the profile material on the knives of the knife building cling group, so that neither a perfect cutting process nor a clean melting and joining of the cut edges is possible.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Schneid- und Verbindungsvorrichtung der im Oberbegriff des Patentanspruchs 1 genannten Art zu schaffen, die ein einwandfreies Verbinden nicht nur von anschmelz­ baren Kunststoffmaterialien, sondern auch von anderen nicht schmelzbaren Materialien ermöglicht.The invention has for its object an improved cutting and Connecting device mentioned in the preamble of claim 1 To create a way that not only fuses a perfect connection plastic materials, but also from other non-meltable ones Materials.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. This object is achieved in the characterizing part of the claim 1 specified features solved.  

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements and developments of the invention result itself from the subclaims.

Durch die erfindungsgemäße Ausgestaltung der Vorrichtung ist ein sehr schneller Schneid- und Verbindungsvorgang möglich, da beim Aufwärtsbewe­ gen der mit der Konditioniereinrichtung verriegelten Messerbaugruppe zu­ nächst der Schneidvorgang durchgeführt wird, worauf nach dem Ende des Schneidhubes die Messerbaugruppe gegenüber der Konditioniereinrichtung entriegelt wird und durch Vorspanneinrichtungen nach unten aus dem Be­ reich der Einspanneinrichtungen für die Profilstränge zurückgezogen wird. Die geschnittenen Profile können dann mit der Konditioniereinrichtung in Berührung gebracht werden, worauf diese ebenfalls aus dem Bereich der Einspanneinrichtungen zurückgezogen wird, so daß die Schnittkanten miteinander in Berührung gebracht und miteinander verbunden werden können.Due to the inventive design of the device is a very faster cutting and connection process possible, as when moving upwards towards the knife assembly locked with the conditioning device next the cutting operation is carried out, whereupon after the end of the Cutting stroke the knife assembly opposite the conditioning device is unlocked and by means of pretensioners down from the loading range of the clamping devices for the profile strands is withdrawn. The cut profiles can then be used with the conditioning device be brought into contact, after which these are also from the area the clamping devices is withdrawn so that the cut edges can be brought into contact and connected with each other.

Die Konditioniereinrichtung kann gemäß einer Ausgestaltung der Erfindung durch einen beheizten Schweißbalken gebildet sein, der vorzugsweise mit ei­ nem Teflonüberzug versehen ist, um ein Anhaften von Materialresten an diesem Schneidbalken zu verhindern. Der Teflonüberzug ist bei einer eventuel­ len Abnutzung leicht auswechselbar an dem Schneidbalken befestigt.The conditioning device can be according to an embodiment of the invention be formed by a heated welding bar, preferably with egg Teflon coating is provided to prevent material residues from adhering to prevent this cutting bar. The Teflon cover is at a possible len wear easily replaceable attached to the cutter bar.

Für Profilmaterialien, die nicht anschmelzbar sind, kann der Schweißbalken ohne großen Aufwand durch eine Auftragsvorrichtung für Klebe- und/oder Lösungsmittel ersetzt werden, so daß die Schneid- und Verbindungseinrich­ tung für beliebige Materialien geeignet ist.The welding bar can be used for profile materials that cannot be melted with little effort by an application device for adhesive and / or Solvents are replaced so that the cutting and connecting device device is suitable for any materials.

Die Einspanneinrichtungen sind in einer zu ihren den Schnittkanten benach­ barten Stirnfläche senkrecht verlaufenden Richtung in Richtung auf die zwischen den beiden Einspannvorrichtungen befindliche Messerbaugruppe und Konditioniereinrichtung beweglich, wobei ggf. mit der Bewegung der Messerbaugruppe und der Konditioniereinrichtung synchronisierte Antriebs­ einrichtungen für die Einspanneinrichtungen vorgesehen sein können, so daß sich ein sehr einfacher und schneller Betriebsablauf ergibt.The clamping devices are adjacent to the cutting edges in one beard face perpendicular to the direction knife assembly located between the two clamping devices and conditioning device movable, possibly with the movement of the Knife assembly and the conditioning device synchronized drive  devices for the clamping devices can be provided, so that there is a very simple and fast operation.

Gemäß Fig. 1 befindet sich die Vorrichtung zunächst in der Ruhestellung, in der sowohl die Messer (31) der Messerbaugruppe (30) als auch der Schweißbalken (25) der Konditioniereinrichtung (20) aus dem Bereich zwi­ schen den Einspanneinrichtungen (40) fort bewegt sind. Die Konditionier­ einrichtung (20) sowie die Messerbaugruppe (30) sind hierbei miteinan­ der verriegelt und liegen an dem Anschlag (12) an. Die Profilstrangab­ schnitte werden dann in die Einspanneinrichtungen (40) eingelegt, worauf die Konditioniereinrichtung (20) mit der durch die Verriegelungseinrich­ tungen (23, 33) daran befestigten Messerbaugruppe (30) nach oben bewegt wird. Die Schneidkante (32) der Messer (31) der Messerbaugruppe (30) steht hierbei gegenüber dem Schweißbalken (25) nach oben hin vor, so daß die Schneidkanten mit den Profilstrangabschnitten in Schneideingriff kommen und diese durchtrennen. Die abgeschnittenen Enden können entwe­ der durch Öffnungen zwischen den Messern (31) und dem Schweißbalken (35) herabfallen oder von Hand oder auf andere Weise entfernt werden. Am En­ de des Schneidhubes kommt die Sperrklinke (33) mit der Entriegelungs­ einrichtung (34) gemäß Fig. 1 in Berührung, wodurch die Sperrklinke ent­ riegelt wird und die Messerbaugruppe (30) unter der Wirkung der Vor­ spannfeder (11) nach unten hin gegenüber der Konditioniereinrichtung (20) zurückgezogen wird. Damit befindet sich lediglich noch der Schweiß­ balken (25) zwischen den Einspannvorrichtungen (40), die daraufhin in Richtung auf diesen Schweißbalken (25) vorgeschoben werden können, um die Schnittkanten der Profilstrangabschnitte mit diesem Schweißbalken in Berührung zu bringen. Hierdurch erfolgt ein Anschmelzen der Schnitt­ kanten und der Schweißbalken (25) wird nach dem Anschmelzen der Schnitt­ kanten ebenfalls nach unten bewegt, so daß die Einspannvorrichtungen und damit die Schnittkanten gegeneinander bewegt werden können. Nach dem Abkühlen der so hergestellten Schweißverbindung können die Ein­ spannvorrichtungen (40) geöffnet und die so gebildete Eckverbindung herausgenommen werden.Referring to FIG. 1, the device is initially in the rest position, both the knife (31) of the conditioning device (20) Zvi rule in which the knife assembly (30) and the welding beam (25) from the area of the clamping means (40) moves are. The conditioning device ( 20 ) and the knife assembly ( 30 ) are locked together and lie against the stop ( 12 ). The Profilstrangab sections are then inserted into the clamping devices ( 40 ), whereupon the conditioning device ( 20 ) with the knife assembly ( 30 , 33 ) attached to it by the locking devices ( 23 , 33 ) is moved upwards. The cutting edge ( 32 ) of the knives ( 31 ) of the knife assembly ( 30 ) projects upwards relative to the welding bar ( 25 ) so that the cutting edges come into cutting engagement with the section sections and cut through them. The cut ends can either fall through openings between the knives ( 31 ) and the welding bar ( 35 ) or be removed by hand or in some other way. At the end of the cutting stroke, the pawl ( 33 ) comes into contact with the unlocking device ( 34 ) according to FIG. 1, whereby the pawl is unlocked and the knife assembly ( 30 ) under the action of the pre-tensioning spring ( 11 ) downwards the conditioning device ( 20 ) is withdrawn. So there is only the welding bar ( 25 ) between the clamping devices ( 40 ), which can then be advanced in the direction of this welding bar ( 25 ) in order to bring the cutting edges of the extruded sections into contact with this welding bar. This causes the cut edges to melt and the welding bar ( 25 ) is also moved downward after the cut edges have melted, so that the clamping devices and thus the cut edges can be moved against one another. After the welded connection has cooled down, the clamping devices ( 40 ) can be opened and the corner connection formed in this way can be removed.

Bei der Abwärtsbewegung der Konditionierbewegung (20) gelangt diese wieder in Anlage an die Messerbaugruppe (30), wodurch die Verriegelungs­ klinke (33) wieder in Eingriff mit dem Verriegelungszapfen (23) gelangt und die Vorrichtung für einen neuen Arbeitshub bereit ist.During the downward movement of the conditioning movement ( 20 ) this comes into contact with the knife assembly ( 30 ), whereby the locking pawl ( 33 ) comes back into engagement with the locking pin ( 23 ) and the device is ready for a new working stroke.

Wie dies aus den Fig. 3 und 5 zu erkennen ist, ist der Schweißbalken (25) mit einem Teflonüberzug (26) versehen, der leicht auswechselbar ist, so daß das Anhaften von Materialrückständen an dem Schweißbalken (25) selbst vermieden wird.As can be seen from FIGS. 3 and 5, the welding bar ( 25 ) is provided with a Teflon coating ( 26 ) which is easily exchangeable, so that the adherence of material residues on the welding bar ( 25 ) itself is avoided.

Sofern Profilstränge verarbeitet werden sollen, die nicht anschmelzbar oder durch Schmelzen miteinander verbindbar sind, kann der Schweißbalken (25) der Vorrichtung auch durch eine Auftragsvorrichtung für Klebe- und/ oder Lösungsmittel ersetzt werden, die für das jeweilige zu verarbeiten­ de Material geeignet sind.If profile strands are to be processed which cannot be melted or connected to one another by melting, the welding bar ( 25 ) of the device can also be replaced by an application device for adhesives and / or solvents which are suitable for the particular material to be processed.
