Definitions

  • the invention relates to a cutting device for the circumcision of sheet material such as paper, foil or the like with a flat surface for the support of the sheet material, which provided on one side with a lever cutting device is having a pivotally mounted knife arm with held cutting edge and a fixed to the base having held counter knife.
  • Cutters of the type mentioned above are in particular intended for office use. They serve for circumcision of paper sheets mostly of A4 size and smaller, possibly DIN A3 format.
  • the cutters point at one Long side of a guillotine on.
  • a such guillotine has one at a corner the pad pivotally mounted about a horizontal axis Knife arm, on which a lower side protruding Cutting knife is attached. It corresponds to one attached to the pad counter knife.
  • the knife arm is arranged a handle over which the Knife arm swung down from a raised position can be with the consequence that one over the counter knife above sheet material is cropped.
  • Such Cutters have been in principle for decades same version in the office area in use.
  • sheet material can be relatively cut well if the sheet material is not negligible the counter knife protrudes, otherwise there is a danger that the supernatant through the cutting edge down pressed and not cut clean. It leaves also a sheet pile consisting of several sheets cut at the same time, if the sheet stack a not too high altitude.

Description

Die Erfindung betrifft ein Schneidgerät für die Beschneidung von Blattgut wie Papier, Folien oder dergleichen mit einer flächigen Unterlage für die Auflage des Blattguts, die an einer Seite mit einer Hebelschneideinrichtung versehen ist, die einen schwenkbar gelagerten Messerarm mit daran gehaltener Schneide und ein ortsfest an der Unterlage gehaltenes Gegenmesser aufweist.The invention relates to a cutting device for the circumcision of sheet material such as paper, foil or the like with a flat surface for the support of the sheet material, which provided on one side with a lever cutting device is having a pivotally mounted knife arm with held cutting edge and a fixed to the base having held counter knife.

Schneidgeräte der oben genannten Art (siehe z.B. EP-A-0 234 016) sind insbesondere für Bürozwecke vorgesehen. Sie dienen der Beschneidung von Papierblattgut meist von DIN A4-Format und kleiner, allenfalls DIN A3-Format. Die Schneidgeräte weisen an einer Längsseite eine Hebelschneideinrichtung auf. Eine solche Hebelschneideinrichtung hat einen an einer Ecke der Unterlage um eine horizontale Achse schwenkbar gelagerten Messerarm, an dem ein untenseitig vorstehendes Schneidmesser angebracht ist. Es korrespondiert mit einem an der Unterlage befestigten Gegenmesser. Am freien Ende des Messerarms ist ein Handgriff angeordnet, über den der Messerarm aus einer hochgeschwenkten Stellung heruntergeschwenkt werden kann mit der Folge, daß ein über das Gegenmesser vorstehendes Blattgut beschnitten wird. Solche Schneidgeräte sind seit Jahrzehnten in grundsätzlich gleicher Ausführung im Bürobereich im Einsatz.Cutters of the type mentioned above (See, e.g., EP-A-0 234 016) are in particular intended for office use. They serve for circumcision of paper sheets mostly of A4 size and smaller, possibly DIN A3 format. The cutters point at one Long side of a guillotine on. A such guillotine has one at a corner the pad pivotally mounted about a horizontal axis Knife arm, on which a lower side protruding Cutting knife is attached. It corresponds to one attached to the pad counter knife. At the free end the knife arm is arranged a handle over which the Knife arm swung down from a raised position can be with the consequence that one over the counter knife above sheet material is cropped. Such Cutters have been in principle for decades same version in the office area in use.

Mit derartigen Schneidgeräten läßt sich Blattgut relativ gut schneiden, wenn das Blattgut nicht unerheblich über das Gegenmesser vorsteht, da anderenfalls die Gefahr besteht, daß der Überstand durch die Schneide nach unten gedrückt und nicht sauber abgeschnitten wird. Es läßt sich auch ein aus mehreren Blättern bestehender Blattstapel gleichzeitig schneiden, sofern der Blattstapel eine nicht zu große Höhe hat.With such cutters, sheet material can be relatively cut well if the sheet material is not negligible the counter knife protrudes, otherwise there is a danger that the supernatant through the cutting edge down pressed and not cut clean. It leaves also a sheet pile consisting of several sheets cut at the same time, if the sheet stack a not too high altitude.

Schwierigkeiten bereitet das Erzeugen einer glatten Schneidkante insbesondere dann, wenn der Überstand über das Gegenmesser nur geringfügig ist. Außerdem besteht bei den Hebelschneideinrichtungen die Gefahr, daß die Lagerung des Messerarms mit der Zeit ein Spiel bekommt, so daß es für die Erzeugung eines glatten Schnitts erforderlich ist, den Messerarm mit erheblichem Druck gegen das Gegenmesser zu drücken. Da dieser Zustand an dem Schneidgerät nicht erkennbar ist, kommt es zu unbefriedigenden Schneidergebnissen.Difficulties are creating a smooth Cutting edge, especially when the supernatant over the counter knife is only slightly. It also exists the guillotine the risk that the storage the knife arm gets a game over time, so that it required for the production of a smooth cut is, the knife arm with considerable pressure against the Press counter knife. Because of this condition on the cutter is not recognizable, it comes to unsatisfactory Cutting results.

Der Erfindung liegt die Aufgabe zugrunde, ein Schneidgerät der eingangs genannten Art so zu gestalten, daß auch unter schwierigen Bedingungen gute Schneidergebnisse erzielt werden.The invention is based on the object, a cutting device of the type mentioned above to be designed so that too achieved good cutting results under difficult conditions become.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß - vorzugsweise an einer anderen Seite der Unterlage - eine Rollenschneideinrichtung vorgesehen ist, die einen auf einer Führungsschiene verfahrbaren Messerwagen und ein darin drehbar gelagertes Scheibenmesser aufweist. Grundgedanke der Erfindung ist es also, ein Schneidgerät mit zwei unterschiedlichen Arten von Schneideinrichtungen bereitzustellen, wobei die eine Schneideinrichtung Stärken in dem Bereich hat, in dem die andere Schneideinrichtung weniger gut arbeitet. Während die Hebelschneideinrichtung insbesondere zum Beschneiden von Blattstapeln geeignet ist, zeichnet sich die erfindungsgemäße Rollenschneideinrichtung durch einen sauberen Schnitt selbst bei minimalen Überständen bzw. abzuschneidenden Rändern aus. Sie läßt sich deshalb besonders gut für die Randbeschneidung von Fotodrucken oder dergleichen einsetzen. Das erfindungsgemäße Schneidgerät ist also wesentlich vielseitiger zu gebrauchen und nimmt nicht mehr Raum ein, als bekannte Schneidgeräte der gattungsgemäßen Art.This object is achieved in that preferably on another side of the pad - a Roll cutting device is provided, the one on a guide rail movable knife carriage and a having rotatably mounted disc blade therein. basic idea So it is the invention with a cutting device to provide two different types of cutting devices, wherein the one cutting device strengths in the area where the other cutter works less well. While the lever cutter especially suitable for trimming sheet stacks is, the roll cutting device according to the invention is characterized through a clean cut even at minimal Overhangs or edges to be cut off. she can therefore be particularly good for the edge circumcision from photo printing or the like. The invention Cutting device is therefore much more versatile to use and does not take more space than known Cutting devices of the generic type.

In Ausbildung der Erfindung ist vorgesehen, daß Hebel- und Rollenschneideinrichtung so angeordnet sind, daß sie parallel verlaufende Schneidrichtungen haben. Diese eröffnen die Möglichkeit, Blattgut an beiden Seiten gleichzeitig und absolut parallel zu beschneiden. Dabei könnte der Abstand entsprechend einem bestimmten Standardformat bemessen sein. Zwischen Hebel- und Rollenschneideinrichtung kann noch eine parallel zu den Schneidrichtungen verlaufende Anschlagschiene vorgesehen sein, die quer zu den Schneidrichtungen verschieblich geführt ist. In an embodiment of the invention, it is provided that lever and roll cutting device are arranged so that they have parallel cutting directions. These open up the possibility of sheet material on both sides simultaneously and absolutely cut in parallel. It could the distance according to a certain standard format be measured. Between lever and roller cutting device can still one parallel to the cutting directions extending stop rail be provided, which is transverse to The cutting directions is guided displaceably.

Das Scheibenmesser hat zweckmäßigerweise eine zur Unterlage parallele Drehachse. Dabei sollte das Scheibenmesser mit seiner Schneide an einer Gegenmesserschiene, die beispielsweise aus Kunststoff bestehen kann, anliegen oder zumindest andrückbar sein.The disc knife has expediently one for the pad parallel axis of rotation. It should be the disc knife with its cutting edge on a counter knife rail, for example may consist of plastic, or lie be at least pressable.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Führungsschiene aus einer unteren Schneidstellung in eine obere Ausgangsstellung anhebbar und von dieser wieder in die Schneidstellung absenkbar ist und daß der Spalt zwischen Unterlage und Führungsschiene von den Stirnseiten der Führungsschiene her unzugänglich ist. Dem liegt der Gedanke zugrunde, die Vertikalbewegung des Scheibenmessers nicht durch den Messerwagen, sondern mittels der Führungsschiene zu bewirken, indem die Führungsschiene für das Durchschieben des Schneidgutes zunächst angehoben und dann in die Schneidstellung, in der das Scheibenmesser auf der Unterlage aufliegt, abgesenkt wird. Auf diese Weise ist die Handhabung des Schneidvorgangs wesentlich einfacher und führt zu sauberen Schnitten. Dabei ist von besonderer Wichtigkeit, daß der Spalt zwischen Führungsschiene und Unterlage von den Stirnseiten der Führungsschiene unzugänglich ist, also dort abgedeckt ist, so daß es in diesem Bereich nicht möglich ist, daß Finger der Bedienungsperson in den Spalt gelangen und beim Absenken der Führungsschiene eingeklemmt werden.According to a further feature of the invention is provided that the guide rail from a lower cutting position can be raised to an upper initial position and from this is lowered back into the cutting position and that the Gap between base and guide rail of the End faces of the guide rail is inaccessible. the the idea is based on the vertical movement of the Disc knife not by the knife carriage, but by means of to effect the guide rail by the guide rail for pushing through the material to be cut first lifted and then into the cutting position in which the Disc knife rests on the base, lowered becomes. In this way, the handling of the cutting process much easier and leads to clean cuts. It is of particular importance that the gap between guide rail and pad from the end faces the guide rail is inaccessible, so covered there is so that it is not possible in this area that operator's fingers get into the gap and be clamped when lowering the guide rail.

In weiterer Ausbildung der Erfindung ist vorgeschlagen, daß die Führungsschiene im Bereich Ihrer Stirnseiten vertikal verschieblich geführt ist, so daß sie parallel zur Unterlage angehoben und abgesenkt werden kann, und zwar vorzugsweise um nicht mehr als 20 mm, vorzugsweise ca. 12 mm. Alternativ dazu kann jedoch auch vorgesehen sein, daß die Führungsschiene im Bereich einer Stirnseite um eine horizontale Achse verschwenkbar gelagert ist, und zwar maximal um einen Winkel von 10°, vorzugsweise von 4 - 5°. Damit der Spalt zwischen Unterlage und Führungsschiene an den beiden Stirnseiten der Führungsschiene unzugänglich ist, sollten diese Stirnseiten mit der Unterlage überlappen. Es versteht sich, daß diese Überlappung bei einer schwenkbar gelagerten Führungsschiene nur an deren freien Ende und nicht im Bereich des Schwenklagers notwendig ist, da das Schwenklager selbst schon ein Hindernis für den Zugang in den Spalt zwischen Unterlage und Führungsschiene bildet. Soweit eine Überlappung vorgesehen ist, kann dies durch eine mit der Unterlage überlappende, nach unten vorstehende Schutznase geschehen. Damit die Führungsschiene in diesem Bereich seitlich gut geführt ist, sollte die Schutznase in einen passenden Schlitz in der Unterlage einfassen.In a further embodiment of the invention, it is proposed that the guide rail is vertical in the area of your end faces slidably guided, so that they parallel to Pad can be raised and lowered, and indeed preferably not more than 20 mm, preferably about 12 mm. Alternatively, however, it may also be provided that the guide rail in the region of one end face around one Horizontal axis is pivotally mounted, and indeed at most by an angle of 10 °, preferably 4-5 °. So that the gap between the base and guide rail the two end faces of the guide rail inaccessible is, these faces should overlap with the base. It is understood that this overlap at a pivotally mounted guide rail only at the free End and not necessary in the area of the pivot bearing is because the pivot bearing itself already an obstacle to the access in the gap between base and guide rail forms. As far as an overlap is provided, This can be done by overlapping with the pad, after Protective nose protruding down done. So that the guide rail is guided well in this area, The protective nose should fit into a matching slot in the Border underlay.

Die Führungsschiene kann so aufgehängt sein, daß sie ohne Betätigung die Schneidstellung einnimmt, bei der das Scheibenmesser auf der Unterlage aufsitzt. Für das Durchschieben des Blattgutes durch den Spalt zwischen Führungsschiene und Unterlage kann die Führungsschiene von Hand angehoben werden. Alternativ dazu besteht jedoch auch die Möglichkeit, daß die Führungsschiene ohne Betätigung mittels einer Feder in der Ausgangsstellung gehalten ist. Dies erleichtert das Durchschieben des Blattgutes durch den Spalt, erfordert allerdings das Niederdrükken der Führungsschiene für den Schneidvorgang. Gleichwohl gelingt auch mit dieser Ausführungsform ein sauberer Schnitt, weil das Niederdrücken der Führungsschiene mit der einen Hand und die Verschiebung des Messerwagens mit der anderen Hand erfolgen kann, was in der Handhabung deutlich einfacher ist als bei den bekannten Rollenschneideinrichtungen, bei denen der Messerwagen niedergedrückt und gleichzeitig verschoben werden muß.The guide rail can be hung so that they without Actuation occupies the cutting position, in which the Disc knife is seated on the base. For pushing through of the sheet material through the gap between the guide rail and underlay can be the guide rail of Hand raised. Alternatively, however, there is also the possibility that the guide rail without operation held by a spring in the starting position is. This facilitates the pushing through of the sheet material through the gap, however, requires the Niederdrükken the guide rail for the cutting process. nevertheless also succeeds with this embodiment, a cleaner Cut, because the depression of the guide rail with the one hand and the displacement of the knife carriage with the other hand can do what is in the handling is significantly easier than in the known slitter-cutting devices, where the knife carriage depressed and must be moved at the same time.

Nach der Erfindung ist des weiteren vorgesehen, daß die Führungsschiene an ihrem bzw. ihren höhenbeweglichen Ende(n) mit einer Blockiereinrichtung bzw. Blockiereinrichtungen in der Schneidstellung festlegbar ist. Auf diese Weise ist die Führungsschiene für den Schneidvorgang fixiert und kann sich nicht selbsttätig bewegen bzw. muß nicht während des Schneidvorgangs niedergedrückt werden, wenn dem eine Feder entgegenwirkt. Dies erleichtert die Bedienung des Schneidgerätes.According to the invention it is further provided that the Guide rail at its or her höhenbeweglichen end (s) with a blocking device or blocking devices can be fixed in the cutting position. To this Way, the guide rail is fixed for the cutting process and can not move on its own not be depressed during the cutting process, when counteracting a spring. This facilitates the Operation of the cutting device.

Die bzw. jede Blockiereinrichtung ist vorzugsweise als Schnappeinrichtung ausgebildet, in die die Führungsschiene bei der Bewegung in die Schneidstellung selbsttätig und entriegelbar einschnappt, so daß die Fixierung der Führungsschiene in der Schneidstellung nicht mit zusätzlichen Handhabungen verbunden ist. Lediglich für den Entriegelungsvorgang nach dem Schneidvorgang ist eine Betätigung der Schnappeinrichtung zwecks deren Entriegelung notwendig. Hierzu kann die Schnappeinrichtung einen Betätigungsschieber aufweisen, der an günstiger Stelle angebracht ist.The or each blocking device is preferably as Snap device formed in the guide rail automatically when moving into the cutting position and unlocks snaps, so that the fixation of the Guide rail in the cutting position not with additional Handling is connected. Only for the unlocking process after the cutting process is an operation the snap device for the purpose of unlocking necessary. For this purpose, the snap device can be an actuating slide have, which attached in a favorable place is.

In weiterer Ausgestaltung der Erfindung ist vorgeschlagen, daß die Unterlage einen Bereich mit einer elastischen Schneide, vorzugsweise aus einem elastomeren Werkstoff bestehenden Schneidunterlage aufweist und die Führungsschiene mit dem Messerwagen dem Schneidgerät lose zugeordnet ist. Auf diese Weise hat der Benutzer die Möglichkeit, die Rollenschneideinrichtung innerhalb des Bereichs der elastischen Schneidunterlage unterschiedlich anzuordnen und einzusetzen. Dabei sollte die Führungsschiene von einer Auflageplatte hochstehen, die auf der Schneidunterlage auflegbar ist. Vorzugsweise besteht die Auflageplatte aus einem transparenten Kunststoff, wobei Linien vorgesehen sein können, die sich parallel zur Führungsschiene erstrecken und eine Ausrichtung der Führungsschiene erlauben.In a further embodiment of the invention, it is proposed that the pad an area with an elastic Cutting edge, preferably made of an elastomeric material having existing cutting pad and the guide rail with the knife carriage loose the cutter assigned. In this way, the user has the option the winder inside the area the elastic cutting pad different to arrange and use. The guide rail should be stand up from a platen on top of the Cutting pad can be placed. Preferably, the Supporting plate made of a transparent plastic, wherein Lines may be provided which are parallel to the guide rail extend and an orientation of the guide rail allow.

Nach der Erfindung ist ferner vorgesehen, daß die Hebelschneideinrichtung gegen die Rollenschneideinrichtung und umgekehrt austauschbar ist. Auf diese Weise kann die Unterlage wechselweise mit derjenigen Schneideinrichtung versehen werden, die für den jeweiligen Schneidvorgang besonders geeignet ist. Soll beispielsweise ein Blattgut aus mehreren Lagen Papier oder Folien beschnitten werden, wird die Hebelschneideinrichtung mit der Unterlage verbunden. Sollen einzelne Fotos oder dergleichen beschnitten werden, wird die Hebelschneideinrichtung durch die Rollenschneideinrichtung ersetzt, da sie sich hierfür besonders eignet. Der Vorteil der Austauschbarkeit gegenüber einer festen Anordnung beider Schneideinrichtungen besteht darin, daß die eine Schneideinrichtung beim Beschneiden durch die andere Schneideinrichtung nicht störend für die Auflage des Blattgutes ist. Dies ermöglicht es auch, die Unterlage in Richtung quer zur Längsachse der jeweiligen Schneideinrichtung relativ kurz zu halten und damit das Schneidgerät kompakt und damit auch leicht transportabel zu gestalten.According to the invention it is further provided that the lever cutting device against the slitter and conversely, it is interchangeable. In this way, the pad can alternately with that cutting device be provided for each cutting process is particularly suitable. For example, if a sheet material be trimmed from several layers of paper or foil, the lever cutter is connected to the base. Shall cut individual photos or the like be, is the lever cutter by the Reel cutter replaced, as they are special for this suitable. The advantage of interchangeability over a fixed arrangement of both cutting devices is that the one cutter when pruning not disturbing by the other cutter for the edition of the sheet material is. this makes possible it also, the pad in the direction transverse to the longitudinal axis the respective cutting device to keep relatively short and thus the cutting device compact and therefore easy transportable.

Die lösbare Verbindung zwischen Unterlage und jeweiliger Schneideinrichtung kann auf verschiedene Art und Weise erfolgen. So können beispielsweise die Unterlage einerseits sowie die Hebelschneidmaschine und die Rollenschneidmaschine andererseits komplementäre Halteelemente aufweisen, über die entweder die Hebelschneideinrichtung oder die Rollenschneideinrichtung an einer Seite der Unterlage anbringbar ist. Dabei sollten die Halteelemente Rasteinrichtungen aufweisen, die eine einfache Anbringung ermöglichen und gleichzeitig sicherstellen, daß die jeweilige Schneideinrichtung in der richtigen Position angebracht wird. Die Rasteinrichtungen können derart ausgebildet sein, daß sie beim Anbringen der Schneideinrichtung selbsteinrastend sind, jedoch bei der Abnahme eine Freigabebetätigung erfordern. Auf diese Weise ist gesichert, daß sich die jeweilige Schneideinrichtung nicht von selber aus der Raststellung lösen kann.The detachable connection between the base and the respective one Cutting device can be done in different ways respectively. Thus, for example, the pad on the one hand as well as the lever cutting machine and the slitter-winder on the other hand complementary holding elements have over which either the lever cutter or the slitter on one side of the pad attachable. The retaining elements should Have latching devices, which is a simple attachment while ensuring that the respective Cutting device mounted in the correct position becomes. The locking devices can be designed in this way be that they when attaching the cutter self-locking, but at the time of acceptance one Require release operation. In this way is secured that the respective cutting device is not can solve by itself from the detent position.

Schließlich ist nach der Erfindung vorgesehen, daß die Unterlage eine quer zur Längsachse der Hebel- bzw. Rollenschneideinrichtung ausziehbare und einfahrbare Zusatzunterlage aufweist. Auf diese Weise kann die Unterlage für das Beschneiden größerer Formate wesentlich verlängert werden. Für kleinere Formate und für den Transport des Schneidgeräts kann die Zusatzunterlage in die Hauptunterlage eingefahren werden, so daß das Schneidgerät nur geringen Raumbedarf hat.Finally, it is provided according to the invention that the Pad one transverse to the longitudinal axis of the lever or roller cutting device retractable and retractable additional pad having. In this way, the pad can significantly extended for trimming larger formats become. For smaller formats and for transport of the cutter, the additional pad in the main pad be retracted so that the cutter has only small space requirements.
