Abstract

The sheets (20) to be cut along both sides (12, 13) are guided through a holding arrangement of two transversally positioned round aluminum bars (1, 2). Both bars (1, 2) are fitted with complementary upper and lower blades (3, 4). A krypton laser head (7) is located at an appropriate distance in order to emit a laser beam (9) in the shape of a red line (19) visible on the sheet (20). The blades (3, 4) can be adjusted by using the line (19) as a reference element.

Description

Die Erfindung betrifft eine Schneidmesseranordnung an einer Konfektioniermaschine für Papier- oder Folienbahnen, die zur Weiterverarbeitung geschnitten werden, mit wenigstens einem entlang der Bahnbreite einstellbaren Schneidmesser, bei der das oder die Schneidmesser verschiebbar und justierbar an wenigstens einer Führungsschiene der Konfektioniermaschine angeordnet sind.The invention relates to a cutting blade arrangement on a finishing machine for paper or film webs, which are cut for further processing, with at least one along the web width adjustable cutting blade, in which the or the cutting blades are slidably and adjustably arranged on at least one guide rail of the packaging machine.

Bei Konfektioniermaschinen mit einer Schneidmesseranordnung werden die Schneidmesser entsprechend der gewünschten Schnittposition manuell eingestellt, wobei mithilfe von Maßstäben und Schablonen die Position festgelegt wird.In confectioning machines with a cutting blade arrangement, the cutting blades are adjusted manually according to the desired cutting position, the position being determined by means of scales and templates.

Nachteilig hierbei ist, dass bei einer seitlichen Verstellung der Schneidmesser im Laufe des Produktionsprozesses diese Fehler kaum bemerkt werden, da eine schwache seitliche Verschiebung nicht beobachtet werden kann. Weiterhin ist bei einer Änderung der Position der Schneidmesser eine umständliche Neujustierung und Neuvermessung erforderlich.The disadvantage here is that with a lateral adjustment of the cutting blade in the course of the production process, these errors are barely noticed, since a weak lateral displacement can not be observed. Furthermore, a change in the position of the cutting blade requires a laborious readjustment and remeasurement.

Es stellt sich die Aufgabe, bei einer Schneidmesseranordnung an einer Konfektioniermaschine hier die Einstellung zu vereinfachen, wobei es möglich sein soll, dass während des teilweise lang dauernden Konfektionierablaufes eine Beobachtung der Position der Schneidmesser in einfacher Weise möglich sein soll.It raises the task of simplifying the setting in a cutting blade assembly on a packaging machine here, it should be possible that during the sometimes long-lasting packaging process, an observation of the position of the cutting blade should be possible in a simple manner.

Die Aufgabe wird dadurch gelöst, dass an der Konfektioniermaschine zusätzlich zu der Führungsschiene mit den Schneidmessern eine längsparallel und beabstandet gegenüber der Führungsschiene verlaufende Tragschiene angebracht ist, an der wenigstens ein lichtemittierendes Element, insbesondere Laser, mit sichtbarer Strahlung verstellbar angeordnet ist, dessen gebündelter Lichtstrahl auf eine gewünschte Position eines Schneidmessers, das sich auf der Führungsschiene befindet, gerichtet ist und Lichtmarkierungen erzeugt, die der Position entsprechen, nach der das Schneidmesser auszurichten ist.The object is achieved in that on the packaging machine in addition to the guide rail with the cutting blades a longitudinally parallel and spaced from the guide rail extending mounting rail is attached to the at least one light-emitting element, in particular laser, is arranged adjustable with visible radiation whose bundled light beam on a desired position of a cutting knife, which is located on the guide rail, is directed and generates light marks corresponding to the position, after which the cutting blade is to be aligned.

Ein Laser als lichtemittierendes Element ist besonders geeignet, da sein Licht auf eine kleine Fläche gebündelt werden kann, ohne dass zusätzliche optische Fokussierungsmaßnahmen getroffen werden müssen.A laser as a light-emitting element is particularly suitable because its light can be focused on a small area without having to make additional optical focusing measures.

Üblicherweise sind mehrere, d.h. wenigstens zwei Schneidmesser an zwei unmittelbar benachbarten Führungsschienen beweglich angebracht, so dass wenigstens zwei Positionen, gegebenenfalls auch mehr, markiert werden müssen. Daher wird vorzugsweise das lichtemittierende Element an einer Laufkatze angebracht, die an der Tragschiene verschiebbar angeordnet ist.Usually, several, ie at least two cutting blades are movably mounted on two immediately adjacent guide rails, so that at least two positions, possibly more, must be marked. Therefore, the light-emitting element is preferably attached to a trolley, which is arranged displaceably on the mounting rail.

Um eine reproduzierbare und genaue Position der Schneidmesser zu garantieren, wird die Position der Laufkatze und damit der Laserkopfes durch einen präzise steuerbaren Antrieb festgelegt. Als Antriebe für die Laufkatze eignen sich insbesondere geregelte fluidische, elektrische oder magnetische Antriebe, die an sich bekannt sind und die die Laufkatze in höchstem Maße präzise verstellbar und justierbar machen.To ensure a reproducible and accurate position of the cutting blades, the position of the trolley and thus the laser head is determined by a precisely controllable drive. As drives for the trolley are in particular controlled fluidic, electrical or magnetic drives, which are known per se and make the trolley highly adjustable and adjustable to the highest degree.

Als weitere vorteilhafte Maßnahme zur Handhabung der Schneidmesseranordnung wird vorgeschlagen, die Laufkatze mithilfe eines programmgesteuerten Schrittmotors justierbar zu machen.As a further advantageous measure for handling the cutting blade arrangement, it is proposed to make the trolley adjustable by means of a program-controlled stepping motor.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert. Die Figuren der Zeichnung zeigen:

An embodiment of the invention will be explained with reference to the drawing. The figures of the drawing show:
Fig. 1
a schematic representation of the attached to guide rails of a confectioning Schneidmeser with mounting rails and light-emitting element;
Fig. 2
the arrangement of FIG. 1 seen in the axial direction of the guide rails, and
Fig. 3
schematically a confectioning machine with built-in arrangement according to the Fig.1, also seen in the axial direction of the guide rails.

Die Figuren 1 und 2 zeigen Teile einer Konfektioniermaschine für Papier- und Folienbahnen 20, die durch randseitiges Beschneiden für eine Weiterverarbeitung vorbereitet werden. Bei dem Material der Bahnen kann es sich außer Papier oder Kunststoff-Folien auch um textile Bahnen, beispielsweise Gewebe oder Gewirke, handeln. Dabei durchläuft die Bahn 20 in Pfeilrichtung P eine Schneidstation 10. Die Bahn 20 wird, wie aus den Figuren 2 und 3 zu ersehen, über zwei Führungsrollen 11 und 21 geführt, die Bestandteil der schematisch in Fig. 3 dargestellten Konfektioniermaschine sind. Hierbei ist die Bahn 20 mit einer Strichlinie angedeutet.Figures 1 and 2 show parts of a confectioning machine for paper and film webs 20, prepared by marginal trimming for further processing become. In addition to paper or plastic films, the material of the webs can also be textile webs, for example woven or knitted fabric. The web 20 passes through a cutting station 10 in the direction of the arrow P. The web 20, as can be seen from FIGS. 2 and 3, is guided over two guide rollers 11 and 21, which form part of the packaging machine shown schematically in FIG. Here, the web 20 is indicated by a dashed line.

Die Schneidstation 10 besteht aus zwei oberhalb der Bahn 20 angeordneten Führungsschienen 1 und 2 aus runden Aluminium-Stäben. Die Führungsschiene 1 ist mit zwei oberen Schneidmessern 3 und die untere Führungsschiene 2 mit zwei unteren Schneidmessern 4 bestückt. Die Festlegung der Schneidmesser 3 und 4 erfolgt entsprechend der gewählten Position nach Ausmessen durch Festlegung mittels Schrauben oder Klemmen.The cutting station 10 consists of two above the track 20 arranged guide rails 1 and 2 of round aluminum rods. The guide rail 1 is equipped with two upper cutting blades 3 and the lower guide rail 2 with two lower cutting blades 4. The determination of the cutting blade 3 and 4 is carried out according to the selected position after measuring by fixing by means of screws or clamps.

Jeweils ein Messerpaar 3 und 4 wirkt zusammen und bildet einen Teil der Schneidstation 10. Das Zusammenwirken der Messerpaare ergibt einen exakten Schnitt S, wobei randseitig Abfallteile 12, 13 abgeschnitten werden. Selbstverständlich sind auch andere Schneidpositionen möglich. Beispielsweise können auch drei oder mehr Messer nebeneinander angeordnet sein, wenn zum Beispiel eine Bahn in viele Streifen zerschnitten werden soll.In each case a pair of knives 3 and 4 cooperates and forms part of the cutting station 10. The interaction of the pairs of knives results in an exact cut S, whereby edge portions 12, 13 are cut off. Of course, other cutting positions are possible. For example, three or more knives may be arranged side by side, if, for example, a web is to be cut into many strips.

Wesentliche Voraussetzung für ein brauchbares Arbeitsergebnis ist eine exakte Einstellung der Position der Schneidmesser 3, 4, da das Material zur Weiterverarbeitung bestimmt ist.An essential prerequisite for a useful work result is an exact adjustment of the position of the cutting blades 3, 4, since the material is intended for further processing.

Um die Schneidmesser 3, 4 exakt positionieren zu können, wird mithilfe eines aus sichtbarem Licht bestehenden Laserstrahls 9 eine optische Markierung 19 auf der Führungsschiene 1, 2 und auf der Bahn 20 erzeugt. Die Markierung 19 hat durch die Gestaltung des Laserstrahls 9 als Fächerstrahl die Gestalt einer roten Linie, so dass per Handverschiebung jedes der Schneidmesser 3 oder 4 an dieser Linie bzw. Markierung 19 auszurichten ist, die exakt dem durchzuführenden Schnitt S entspricht. Auch ist eine Kontrolle während des Arbeitsvorganges möglich, da bei Abweichen des Schnittes von der Linie dies sofort zu erkennen ist.In order to be able to position the cutting knives 3, 4 exactly, an optical marking 19 is produced on the guide rail 1, 2 and on the web 20 by means of a laser beam 9 made of visible light. The marking 19 has the shape of a red line as a fan beam due to the design of the laser beam 9, so that by manual displacement each of the cutting blades 3 or 4 is to be aligned with this line or marking 19 which exactly corresponds to the cut S to be made. Also, a control during the operation is possible, since it is immediately recognizable when departing from the line of the cut.

Der Laserstrahl 9 wird mithilfe eines Laserkopfes 7, z. B. eines Krypton-Laserkopfes, über einen Diffusor als Fächerstrahl 9 erzeugt und abgestrahlt, und auf die Bahn 20 im Bereich der Schneidstation 10 gerichtet. Der Laserkopf 7 ist mit einer Laufkatze 6 verbunden, die entlang einer Tragschiene 5 beweglich angeordnet ist. Die Tragschiene 5 ist längs parallel und beabstandet gegenüber der Führungsschiene ebenfalls an der Konfektioniermaschine befestigt, beispielsweise durch Tragbügel (hier nicht dargestellt). Mithilfe eines Servomotors 8 wird eine Verschiebung der Laufkatze 6 von der Position I (links) zu einer Position II (rechts) ermöglicht. Der Servomotor 8 ist ein elektronisch präzise geregelter Schrittmotor, der über einen Computer (nicht dargestellt) mit gespeicherter Positionsvorgabe gesteuert und geregelt wird.The laser beam 9 is using a laser head 7, z. B. a krypton laser head, generated and emitted via a diffuser fan beam 9, and directed to the web 20 in the region of the cutting station 10. The laser head 7 is connected to a trolley 6, which is movably arranged along a support rail 5. The support rail 5 is longitudinally parallel and spaced from the guide rail also attached to the packaging machine, for example by mounting bracket (not shown here). By means of a servomotor 8, a displacement of the trolley 6 from the position I (left) to a position II (right) is possible. Servomotor 8 is an electronically precisely controlled stepper motor which is controlled and regulated by a stored position preset computer (not shown).

Hierzu können entsprechende Steuerungstastaturen, (Touch-Screen-Elemente) vorgesehen werden. Durch die Bedienungsperson oder ein vorgegebenes Programm können die Positionen bestimmt werden, an denen sich die Schneidmesser befinden sollen. Auch ist eine programmierte Steuerung möglich, um den Arbeitsablauf zu beschleunigen.For this purpose, appropriate control keyboards, (touch-screen elements) can be provided. By the operator or a predetermined program, the positions at which the cutting blades are to be determined. Programmed control is also possible to speed up the workflow.

Die seitlich abgeschnittenen Teile 12, 13 werden von der Bahn entfernt. Durch zusätzliche Sensoren kann kontrolliert werden, ob die erzeugte Schnittkante genau den Vorgaben entspricht. Hierdurch können Bandeinlauf und Messerposition exakt aufeinander abgestimmt werden, auch während der Produktion.The laterally cut parts 12, 13 are removed from the web. Additional sensors can be used to check whether the generated cutting edge exactly meets the specifications. As a result, the tape feed and knife position can be precisely matched, even during production.

Die Laufkatze 6 kann mit verschiedenen steuer- und regelbaren Antrieben versehen sein, beispielsweise mit fluidischen, elektrischen oder magnetischen Antrieben. Vorzugsweise wird jedoch ein programmgesteuerter Schrittmotor 8 verwendet.The trolley 6 may be provided with various controllable and controllable drives, for example with fluidic, electrical or magnetic drives. Preferably, however, a program-controlled stepping motor 8 is used.
