Description

Laminiereinrichtung laminating
Die Erfindung betrifft eine Laminiereinrichtung mit insbesondere einem Tischblech zur Führung von Laminat zu einem Trennmesser.The invention relates to a laminating device with, in particular, a table top for guiding laminate to a separating knife.
Eine relativ dünne und „endlose" Folie aus einem Kunststoffmaterial wird mit einem Bogen einer Laminiereinheit, umfassend eine Folienwalze und eine Bogenwalze zugeführt und im Walzenspalt erfolgt die Laminierung. Die Haftung zwischen Bogen und Folie kann durch verschiedene Verfahrensvarianten herbeigeführt werden (z. B. Wasser-, Thermo- oder SF-Laminieren). Häufig werden die einzelnen, aufeinanderfolgenden Bogen unterlappt den Walzen zugeführt, um das Verkleben der Folie auf der Gegendruckwalze zu verhindern.A relatively thin and "endless" film of a plastic material is fed with a sheet to a laminating unit comprising a film roll and a sheet roll, and lamination occurs in the nip.The adhesion between sheet and film can be achieved by various process variants (eg water -, Thermo or SF-laminating.) Frequently, the individual, successive sheets underlaid supplied to the rollers to prevent the adhesion of the film on the platen roller.
Vor der Weiterverarbeitung in einem nachgeordneten Prozess muss das Laminat wiederum zu einzelnen Bogen vereinzelt werden, da die Bögen durch die Folie miteinander verbunden sind.Before further processing in a downstream process, the laminate must again be singulated into individual sheets, since the sheets are connected to one another by the film.
Die Trennung erfolgt zum Beispiel mittels rotierender Messer. So beschreibt die EP-B- 706863 eine Vorrichtung zum Trennen von Laminat mit einem, mit der Geschwindigkeit des Laminates mitbewegbaren Schneidmesser, das als thermisches Schneidmesser ausgebildet ist, dessen Umlaufgeschwindigkeit computergesteuert ist.The separation takes place for example by means of rotating knives. Thus, EP-B-706863 describes a device for separating laminate with a, at the speed of the laminate with mitbewegbaren cutting knife, which is designed as a thermal cutting knife whose rotational speed is computer controlled.
Das Laminat wird hierbei auf einem Tischblech der Schneidstation zugeführt. In der DE- A-10028070 ist ein ebenes Tischblech offenbart, das Ausnehmungen für optische Sensoren enthält. Ermöglicht werden soll eine formatgesteuerte Kontrolle der Bogenvorder- kante. Ein Anlegetisch gemäss der DE-A-10355459 soll eine sichere Führung von Bögen vom Anlegetisch zu einem Übergabezylinder ermöglichen, weshalb eine Tischblechoberseite konzentrisch um einen Gestellpunkt eines rotierenden Vorgreifers geführt ist und geringfügig unterhalb eines Flugkreises der Greiferaufschlagleisten verläuft. Für Schneidstationen sind weiterhin ebene und klappbare Tischbleche bekannt. Ebenfalls bekannt ist eine Ausführung, bei welcher die Bogenbahn vor und nach dem Trennmesser mittels Rollen auf Transportwalzen geklemmt wird. Das Tischblech zwischen den Walzen liegt unterhalb der Bogenbahn, sodass die gespannte Bogenbahn während des Trennprozesses praktisch nicht mit dem Tisch in Kontakt kommt. Beide Ausführungsformen haben den Nachteil, dass sie für hohe Trennleistungen und Trenngenauigkeiten nicht geeignet sind.The laminate is fed to the cutting station on a tabletop. DE-A-10028070 discloses a flat table top containing recesses for optical sensors. A format-controlled check of the sheet leading edge is to be made possible. A feed table according to DE-A-10355459 is intended to allow safe guidance of sheets from the feed table to a transfer cylinder, which is why a table top is guided concentrically around a frame point of a rotating pregripper and slightly below a circle of the gripper charge strips. For cutting stations flat and folding tabletops are still known. Also known is an embodiment in which the sheet web is clamped before and after the cutting knife by means of rollers on transport rollers. The tabletop between the rollers is below the arcuate path, so that the stretched arcuate path during the separation process practically does not come into contact with the table. Both embodiments have the disadvantage that they are not suitable for high separation performance and separation accuracies.
Der Erfindung liegt die Aufgabe zugrunde, die Nachteile des Standes der Technik zu meiden und eine Laminiereinrichtung mit einem Tischblech zu schaffen, das eine hochgenaue und parallele Anlage der Bögen am Schneidmesser ermöglicht.The invention has for its object to avoid the disadvantages of the prior art and to provide a laminator with a table top, which allows a highly accurate and parallel conditioning of the sheets on the cutting blade.
Die Aufgabe ist mit den Merkmalen des Patentanspruchs 1 gelöst. Das Tischblech ist ein ebenes Blech, das vorgespannt wird. Die Vorspannung ermöglicht eine Höhenregulierung, guten Kontakt im Trennbereich und eine hohe Dynamik (hohe Maschinenleistung).The object is solved with the features of claim 1. The table top is a flat sheet that is pre-stressed. The preload allows height adjustment, good contact in the separation area and high dynamics (high machine performance).
Bevorzugte Ausführungsformen sind in den Unteransprüchen offenbart. Bevorzugt ist das Tischblech zumindest im Trennbereich elektrisch isoliert und hitzebeständig. Die maximal auftretenden Temperaturen des Trennmessers betragen bis 5500C. Im vorgespannten Zustand bildet das Tischblech ein kreissegmentförmiges Profil. Die von der Schneideinrichtung entfernte Seite des Tischbleches ist lose eingespannt.Preferred embodiments are disclosed in the subclaims. Preferably, the tabletop is electrically insulated and heat resistant at least in the separation area. The maximum occurring temperatures of the cutting blade are up to 550 0 C. In the prestressed state, the tabletop forms a circular segment-shaped profile. The remote from the cutter side of the table top is loosely clamped.
Dies ergibt eine präzise Planlage parallel zum Schneidmesser und eine einfache Höhenregulierung, sowie guten Kontakt im Trennbereich.This results in a precise flatness parallel to the cutting blade and a simple height adjustment, as well as good contact in the separation area.
Die Erfindung wird nachfolgend in einem Ausführungsbeispiel anhand einer Zeichnung näher beschrieben. In der Zeichnung zeigen dieThe invention will be described below in an embodiment with reference to a drawing. In the drawing show the

Fig. 2: eine TischblechanordnungFig. 2: a tabletop assembly
Fig. 3: weitere Ausführungsform einer Tischblechanordnung. In einer Laminiermaschine wird ein Laminat 3, bestehend aus einer Kunststofffolie 1 und einem Bogen 2 in bekannter Weise von einem Laminierwerk 4 kontinuierlich einer Schneideinrichtung 5 mit einem Heissmesser 6 zugeführt. Die vereinzelten Bögen gelangen auf einen Transporttisch 7.3 shows another embodiment of a table top arrangement. In a laminating machine, a laminate 3 consisting of a plastic film 1 and a sheet 2 is fed in a known manner by a laminating unit 4 continuously to a cutting device 5 with a hot knife 6. The isolated sheets arrive at a transport table 7.
Auf das Schneidmesser 6 folgt ein vorgespanntes (gefedertes) zweiteiliges Tischblech 8, welches auf der, dem Schneidmesser 6 zugewandten Seite in einer festen Einspannung verankert ist. Der festen Einspannung ist eine Höhenverstellung 9 zugeordnet. Die vom Schneidmesser 6 abgewandte Seite des Tischbleches 8 ist verschiebbar lose in einer Blechführung 12 eingespannt.On the cutting blade 6 is followed by a biased (spring-loaded) two-piece table top 8, which is anchored on the, the cutting blade 6 facing side in a fixed clamping. The fixed clamping is assigned a height adjustment 9. The side facing away from the cutting blade 6 of the table plate 8 is slidably clamped loose in a sheet guide 12.
Die beiden Teile des Tischbleches 8 sind mittels eines dazwischen liegenden Teflonbalkens 11 fest verbunden. Der Teflonbalken 11 ist durch ein Al-Stützprofil 13 abgestützt und gewährt die Ebenheit im Kontaktbereich zum Schneidmesser 6. Einlaufseitig ist der Teflonbalken 11 abgeschrägt um ein schonendes "Auflaufen" des rotierenden Schneidmessers 6 zu gewährleisten.The two parts of the table plate 8 are firmly connected by means of an intermediate Teflon bar 11. The Teflon bar 11 is supported by an Al support profile 13 and grants the flatness in the contact area to the cutting blade 6. The inlet side of the Teflon bar 11 is chamfered to ensure a gentle "emergence" of the rotating cutting blade 6.
Der Transporttisch 7 weist einen Bandteppich und eine Reisswalze 10 auf, die auch parallel verstellbar ist zur Bogenvereinzelung. The transport table 7 has a belt carpet and a tear roller 10, which is also adjustable in parallel for sheet separation.
