Description

Die Erfindung betrifft eine Vorrichtung zum Durchschneiden, Einschneiden, Durchperforieren oder Einperforieren von Blattmaterial, wie Papieren, Metallfolien oder Kunststoffolien, insbesondere von auf einem nicht zu beeinträchtigenden Trägermaterial befindlichen Etikettenmaterial, mittels einer lösbar koaxial zwischen einer Widerlagerscheibe und einer Andruckscheibe einzuspannenden Schneidscheibe, deren Außendurchmesser etwas größer ist als der Außendurchmesser der Widerlagerscheibe und der Andruckscheibe.The invention relates to a device for cutting through, cutting, perforating or perforating sheet material, such as paper, metal foils or plastic foils, in particular label material located on a carrier material that is not to be affected, by means of a cutting disk that can be releasably coaxially clamped between an abutment disk and a pressure disk, the outside diameter of which is somewhat is larger than the outer diameter of the abutment plate and the pressure plate.

Bei einer nach der DE-OS 30 13 098 bekannten Vorrichtung dieser Art ist die Schneidscheibe an ihrem Umfang mit einer Schneide versehen, die bei der Schneidarbeit bzw. Perforierarbeit einem erheblichen Verschleiß unterworfen ist, der zu zunehmend unschärfer werdenden Schneidkanten bzw. Perforationskanten im Blattmaterial führt, so daß die Schneidscheibe verhältnismäßig häufig erneuert werden muß.In a device of this type known from DE-OS 30 13 098, the cutting disc is provided on its periphery with a cutting edge which is subjected to considerable wear during cutting work or perforation work, which leads to increasingly blurred cutting edges or perforation edges in the sheet material , so that the cutting disc must be replaced relatively often.

Aufgabe der Erfindung ist es, eine Vorrichtung genannter Art anzugeben, deren Schneidscheibe in geringerem Maß verschleißanfällig ist.The object of the invention is to provide a device of the type mentioned, the cutting disc is less susceptible to wear.

Zur Lösung dieser Aufgabe ist die Vorrichtung dadurch gekennzeichnet, daß die Schneidscheibe eine so geringe Dicke hat, daß mit ihrer Umfangsfläche die Schneidarbeit bzw. Perforierarbeit auszuführen ist.To achieve this object, the device is characterized in that the cutting disk has such a small thickness that the cutting work or perforating work can be carried out with its peripheral surface.

Bei dieser Lösung der Aufgabe ging die Erfindung von der Feststellung aus, daß auch eine Schneidscheibe mit einer abgerundeten Umfangsfläche Schneidarbeit und Perforierarbeit leisten kann, eine solche abgerundete Umfangsfläche verhältnismäßig geringfügig verschleißanfällig ist und auch nach Verschleiß noch gleichmäßig saubere Schneidarbeit bzw. Perforierarbeit leisten kann, wenn sie nur eine hinreichend geringe Dicke hat.In this solution to the problem, the invention was based on the finding that a cutting disc with a rounded peripheral surface can perform cutting and perforating work, such a rounded peripheral surface is relatively susceptible to wear and tear and can perform evenly clean cutting or perforating work even after wear, if it has a sufficiently small thickness.

Bevorzugt ist dabei, daß die Umfangsfläche von Anfang an, also vor dem ersten Einsatz der Schneidscheibe, im Querschnitt im wesentlichen symmetrisch zur Mittelebene der Schneidscheibe verläuft und im Scheitelbereich abgerundet ist.It is preferred that the circumferential surface runs from the beginning, ie before the first use of the cutting disc, in cross section essentially symmetrical to the central plane of the cutting disc and is rounded in the apex area.

Wegen der geringen Dicke der Schneidscheibe ist bevorzugt, daß der Außendurchmesser der Schneidscheibe 0,50 mm bis 0,70 mm, vorzugsweise 0,55 mm bis 0,65 mm, größer ist als der Außendurchmesser der Widerlagerscheibe bzw. der Andruckscheibe je nach dem, welcher dieser Außendurchmesser der größere ist, damit die die Schneidarbeit bzw. die Perforierarbeit ausübende Umfangsfläche bei ihrer Arbeit sicher geführt ist.Because of the small thickness of the cutting disk, it is preferred that the outside diameter of the cutting disk is 0.50 mm to 0.70 mm, preferably 0.55 mm to 0.65 mm, larger than the outside diameter of the abutment disk or the pressure disk depending on the which of these outer diameters is the larger so that the circumferential surface performing the cutting work or the perforating work is reliably guided during its work.

Besonders zum Durchschneiden von Etikettenmaterial auf einem Trägermaterial, aber auch in anderen Fällen hat sich bewährt, daß die Dicke der Schneidscheibe 0,08 mm bis 0,19 mm, vorzugsweise 0,1 bis 0,17 mm, beträgt.Particularly for cutting through label material on a carrier material, but also in other cases, it has been found that the thickness of the cutting disc is 0.08 mm to 0.19 mm, preferably 0.1 to 0.17 mm.

Dabei besteht die Schneidscheibe bevorzugt aus Kohlenstoffstahl oder Chromstahl.The cutting disc is preferably made of carbon steel or chrome steel.

Es hat sich erwiesen, daß die Schneidscheibe besonders zuverlässig arbeitet, wenn das zu schneidende oder zu perforierende Blattmaterial auf der der Schneidscheibe abgewandten Seite von einer drehbar gelagerten Widerlagerwalze abgestützt ist.It has been found that the cutting disc works particularly reliably when the sheet material to be cut or perforated is supported on the side facing away from the cutting disc by a rotatably mounted abutment roller.

Dabei besteht bevorzugt die Umfangsfläche - wenn nicht der gesamte Körper - der Widerlagerwalze aus gehärtetem Stahl.The circumferential surface - if not the entire body - of the abutment roller is preferably made of hardened steel.

Ein besonders wirtschaftliches Verfahren zur Herstellung der erörterten Schneidscheiben, aber auch/oder Schneidscheiben, die nicht der genannten Forderung an ihre Dicke genügen, ist dadurch gekennzeichnet, daß Rohlinge der ringförmigen Schneidscheiben aus einem Blech gestanzt werden, daß dann eine Vielzahl dieser Rohlinge (52) als Paket unmittelbar aneinanderliegend auf eine Welle gesteckt, auf der Welle zusammengespannt und als Paket unter Drehen der Welle rundgeschlifffen wird, daß dann die rundgeschliffenen Schneidscheiben vereinzelt waagerecht durch eine Ätzeinrichtung gefördert werden, in der sie von oben und unten mit einer Ätzflüssigkeit besprüht werden, und daß dann die rundgeschliffenen und geätzten Schleifscheiben gewaschen und getrocknet werden.A particularly economical method for producing the cutting disks discussed, but also / or cutting disks that do not meet the above-mentioned requirement for their thickness, is characterized in that blanks are the ring-shaped cutting disks are punched out of a sheet metal, that a large number of these blanks (52) are then placed directly next to one another on a shaft as a package, clamped together on the shaft and ground as a package while rotating the shaft, so that the rounded grinding disks are then isolated horizontally by an etching device are promoted, in which they are sprayed from above and below with an etching liquid, and that the cylindrical and etched grinding wheels are then washed and dried.

Zur Herstellung von Perforationsscheiben werden dabei insbesondere die rundgeschliffenen, geätzten, gewaschenen und getrockneten Schleifscheiben als Paket unmittelbar aneinanderliegend auf eine Welle gesteckt und auf der Welle zusammengespannt und dann in das Paket im Umfangsbereich Axialnuten einer Tiefe von 0,20 mm bis 0,25 mm, vorzugsweise 0,21 mm bis 0,24 mm, geschliffen oder gefräst.To produce perforated discs, the round-ground, etched, washed and dried grinding discs are placed as a package directly next to one another on a shaft and clamped together on the shaft and then into the package in the circumferential area axial grooves with a depth of 0.20 mm to 0.25 mm, preferably 0.21 mm to 0.24 mm, ground or milled.
