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, wobei die Schneidescheibe eine so geringe Dicke hat, daß mit ihren Umfangsfläche die schneidarbeit bzw. Perforierarbeit auszuführen ist. Eine derartige Vorrichtung ist aus der DE-A-4.006.611 bekannt.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 which is not to be affected, by means of a cutting disk which 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 disc and the pressure disc, the cutting disc being so thin that the cutting or perforating work is to be carried out with its peripheral surface. Such a device is known from DE-A-4.006.611.

Bei einer anderen nach der DE-A-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 another device of this type known from DE-A-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 leads, 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 Umfangsfläche aufweist, deren Querschnitt im wesentlichen symmetrisch zur Mittelebene der Schneidscheibe verläuft und in ihrem Scheitelbereich abgerundet ist, und daß zu dem Scheitelbereich von den Seitenflächen der Schneidscheibe aufeinander zu strebende, gerade Flanken führen.To achieve this object, the device is characterized in that the cutting disc has a peripheral surface, the cross section of which is substantially symmetrical to the central plane of the cutting disc and is rounded in its apex region, and that straight flanks are to be striven towards the apex region from the side surfaces of the cutting disc to lead.

Bei der Lösung dieser Aufgabe ging die Erfindung von der Feststellung aus, daß eine Schneidscheibe mit einer abgerundeten Umfangsfläche ausgezeichnete Schneidarbeit und Perforierarbeit leisten kann und dabei verhältnismäßig geringfügig verschleißanfällig ist, dabei auch nach einem Verschleiß noch eine gleichmäßig saubere Schneidarbeit bzw. Perforierarbeit leisten kann, wenn sie nur eine hinreichende Dicke hat, was dadurch erreicht wird, daß sie von Seitenflächen der Schneidscheibe aufeinander zu strebende, gerade Flanken aufweist.In solving this problem, the invention was based on the finding that a cutting disc with a rounded circumferential surface can perform excellent cutting work and perforating work, and is relatively susceptible to wear is, even after wear, can still perform a uniformly clean cutting or perforating work if it has only a sufficient thickness, which is achieved in that it has straight flanks to be strived for from side surfaces of the cutting disc.

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, that is before the first use of the cutting disc, in cross section essentially symmetrically 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 this outer diameter 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 peripheral 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, auch wenn sie nicht der genannten Forderung an ihre Dicke genügen, ist im Anspruch 7 beansprucht.A particularly economical method for producing the cutting disks discussed, even if they do not meet the stated requirement for their thickness, is claimed in claim 7.

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.For the production of perforation 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 in 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.
