Definitions
- the present invention relates to an office appliance for punching, in particular punching of sheet material with a pad for receiving the sheet material, at least one stop for positionally accurate positioning of the sheet material and with a punching device for performing the punching.
- Office equipment of the above type are well known and, for example, in the DE 32 27 301 C2 described. They are used for punching Textilblattgut usually in DIN A4 format.
- Unperforated paper sheets are usually perforated by first folding them into a two-layer arrangement and then placing them in a hole punch and then punching them. For this purpose, the center of the folded sheet is often first determined and then applied to a positioning mark of the punch.
- such a punch is provided with a laterally mounted rail on which the lower edge of the sheet of paper to be punched is placed for positioning the sheet in the punch.
- the paper sheet is to be trimmed to a certain extent, it is necessary to remove the sheet material already aligned for punching from the punch again, to place it in a separate office appliance with a cutting device and to align it again along a cutting edge of the cutting device.
- a disadvantage of this system is further that the handling is very complicated, since the punching device must be moved from punching point to punching point into and out of the device while at the same time has to be considered to position the sheet material again in the introduced punching device.
- the office device has a parallel aligned to the stop guide rail on which the punching device is slidably mounted. This ensures that after positioning of the sheet material to be processed in or relative to the punching device, the introduction of the hole pattern can be done by simply moving the punching device in the guide rail.
- the office equipment along the guide rail arranged stop elements, which allow a determination of the sheet material in certain punching positions in a reproducible manner.
- the stop elements are designed so that they protrude in a stop position in the range of movement of the punching device and are movable from the stop position from the movement range of the punching device in a release position. This ensures that the punching device can be prevented in the punching positions by the stop elements on a further movement within the guide rail and can be moved after the punching operation when the stop elements have been pushed into the release position.
- the stop elements can either be completely led out of the range of movement of the punching device or arranged so that the stop elements are moved over after movement into the release position of the punching device.
- the stop elements are automatically moved by the punching device after overcoming a resistance in the release position. This can be achieved, for example, by that the stop elements are resiliently acted upon in the direction of the stop position.
- stop elements are each formed as between the pad and guide rail on the one hand and the punching device on the other hand effective latching device.
- the latching device during movement of the punching device are displaceable in a cavity below the base and return to its starting position after passing over the punching device.
- the latching devices can be integrally connected, for example via a web in the form of a rocker or each be designed as separate units.
- the stop elements are formed in the contact area with the punching device pyramid-like.
- a particularly space-saving and easy-to-use embodiment of the present invention provides to form the stop elements within the guide rail.
- the stop elements can also be like that be arranged above and / or below the guide rail.
- the office device according to the invention is provided with at least one cutting device, via which the foliage along and / or perpendicular and / or under a particular adjustable angle relative to the stop can be curtailed.
- the cutting direction can be embodied, for example, as a lever cutting device, as a blade cutter or as a roller cutting device. Other other cutting devices known in the art may also be used.
- a hold-down for pressing the sheet material is to be arranged on the Blattgutauflage next to the cutting device, wherein the hold-down between a raised starting position and a displaced in the direction of the base pressing position is movable.
- a hold-down is for example in the EP 1 754 578 A1 to which reference is hereby incorporated by reference.
- the cutting device can be raised from a lower cutting position into an upper initial position and from this back into the cutting position can be brought.
- the gap between the base and the cutting device can be made inaccessible from the end faces of the cutting device. This makes it possible not to carry out the vertical movement of the disc diameter of the cutting device by a knife provided on the cutting device, but to effect by means of the cutting device itself by the cutting device for pushing through the material to be cut first and then into the cutting position in which the disc knife resting on the surface to lower. In this way, the handling of the cutting process is much easier and leads to clean cuts. It is of particular importance that the gap between the cutting device and pad is inaccessible from the end faces of the guide rail, that is covered there, so that it is not possible in this area that fingers of the operator get into the gap and when lowering the guide rail be trapped.
- the guide rail in the region of their end faces is guided vertically displaceable, so that it can be raised and lowered parallel to the pad, and preferably by not more than 20 mm, more preferably by 12 mm.
- the cutting device is mounted pivotably in the region of an end face about a horizontal axis, specifically at a maximum angle of 10 °, preferably 4 to 5 °.
- the cutting device can be suspended so that it assumes the cutting position without actuation, in which the disc knife is seated on the base.
- the cutting device can be lifted by hand.
- the cutting device is held without actuation by means of a spring in the starting position. This facilitates the passage of the sheet material through the gap, however, requires the depression of the guide rail for the cutting process. Nevertheless, a clean cut also succeeds with this embodiment, because the depression of the guide rail with one hand and the displacement of the knife carriage can be done with the other hand, which is much easier to handle than in the known slitter, in which the knife carriage depressed and has to be moved at the same time.
- the guide rail can be fixed in its cutting position in its height-adjustable end (s) with a blocking device or blocking devices.
- the guide rail is fixed for the cutting process and can not move automatically or does not have to be depressed during the cutting process when a spring opposes. This facilitates the operation of the cutter.
- the or each blocking device is preferably designed as a snap device, in which the cutting device snaps automatically and unlockable when moving into the cutting position, so that the fixation of the guide rail is not connected in the cutting position with additional manipulations. Only for the unlocking process after the cutting operation of the snap device for the purpose of unlocking is necessary.
- the snap device may have an actuating slide, which is mounted in a favorable position.
- At least one measuring device is provided on the office appliance.
- the measuring devices can for example be attached to the office appliance via a folding mechanism and be formed by a ruler or a roll measuring device.
- FIG. 1 shows an inventive office device 1 for punching, in particular for punching sheet material 2 with a pad 3 for receiving the sheet material 2 and a stop 4 for positionally accurate positioning of the sheet material 2 within the office device 1.
- the stop 4 is formed in this embodiment in a punching device 5 ,
- the punching device 5 is inserted into a parallel to the stop 4 aligned guide rail 6 and slidably mounted therein as indicated by arrows to perforations in the sheet material 2, each having a constant distance from the voltage applied to the stop 4 edge region of the sheet material 2.
- the punching device 5 is removable from the guide rail 6, whereby a more flexible design of the hole pattern is made possible, for example by using different punching devices with different punched images.
- stop elements 7 are provided, via which the sheet material 2 is reproducibly positionable in the punching device 5.
- the stop elements 7 are arranged at equal distances from each other within the guide rail 6. They have a between the pad 3 and the guide rail 6 on the one hand and the punching device 5 on the other hand effective latching mechanism 9 (see also FIG. 5 ) on.
- the stop elements 7 are first pivoted on movement of the punching device 5 along the guide rail 6 against a spring force F in a cavity below the guide rail 6.
- the stop elements 7 are mounted about a pivot axis S and are moved on displacement of the punching device 5 about the pivot axis S around.
- all stop elements 7 are pivoted together by a common rocker at the same time when driving over only one stop elements 7 by the punching device 5 in the area below the guide rail 6.
- each individual stop element 7 is provided separately with an independent pivoting mechanism 9.
- the stop elements 7 are formed in the contact region with the punching device 5 pyramid-like and have to ease overcoming a resistance generated by the spring force F and thus easier to pass over by the punching device 5 wedge-shaped, rounded edge regions.
- the sheet material 2 is first inserted into the office device 1 and inserted so long in the office device 1 until it stops at the stop 4 and / or the stop elements 7 of the punching device 5 comes.
- the first perforation 12 is introduced when the punching device 5 is in a first end position within the guide rail 6 of the office appliance 1 by a lever 13 of the punching device 5 is moved downward.

Abstract
Description
Die vorliegende Erfindung betrifft ein Bürogerät zum Stanzen, insbesondere Lochen von Blattgut mit einer Unterlage zur Aufnahme des Blattguts, mindestens einem Anschlag zur lagegenauen Positionierung des Blattguts sowie mit einer Stanzvorrichtung zur Durchführung der Stanzung.The present invention relates to an office appliance for punching, in particular punching of sheet material with a pad for receiving the sheet material, at least one stop for positionally accurate positioning of the sheet material and with a punching device for performing the punching.
Bürogeräte der oben genannten Art sind allgemein bekannt und beispielsweise in der
Nachteilig an diesem System ist ferner, dass die Handhabung sehr aufwendig ist, da die Stanzvorrichtung von Stanzpunkt zu Stanzpunkt in die Vorrichtung hinein und aus ihr heraus bewegt werden muss und gleichzeitig dabei zu berücksichtigen ist, das Blattgut immer wieder in der einzuführenden Stanzvorrichtung zu positionieren.A disadvantage of this system is further that the handling is very complicated, since the punching device must be moved from punching point to punching point into and out of the device while at the same time has to be considered to position the sheet material again in the introduced punching device.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Bürogerät bereitzustellen, welches eine einfachere Handhabung ermöglicht.It is therefore an object of the present invention to provide an office appliance, which allows easier handling.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Bürogerät eine parallel zum Anschlag ausgerichtete Führungsschiene aufweist, auf der die Stanzvorrichtung verschiebbar gelagert ist. Dadurch wird erreicht, dass nach Positionieren des zu bearbeitenden Blattguts in oder relativ zu der Stanzvorrichtung die Einbringung des Lochmusters durch einfaches Verschieben der Stanzvorrichtung in der Führungsschiene erfolgen kann.This object is achieved in that the office device has a parallel aligned to the stop guide rail on which the punching device is slidably mounted. This ensures that after positioning of the sheet material to be processed in or relative to the punching device, the introduction of the hole pattern can be done by simply moving the punching device in the guide rail.
Um eine flexiblere Gestaltung der Lochung beispielsweise durch Einsatz verschiedener Stanzgeräte mit unterschiedlichem Stanzbild einsetzen zu können, ist es vorteilhaft, die Stanzvorrichtung von der Führungsschiene abnehmbar auszuführen.In order to be able to use a more flexible design of the perforation, for example by using different punches with different punching image, it is advantageous to perform the punching device of the guide rail detachable.
Zur Erzeugung eines stetig reproduzierbaren Stanzbildes wie beispielsweise der konstanten Beabstandung der Lochungen zueinander, kann in einem Ausführungsbeispiel der vorliegenden Erfindung das Bürogerät entlang der Führungsschiene angeordnete Anschlagelemente aufweisen, die eine Festlegung des Blattguts in bestimmten Stanzpositionen auf reproduzierbare Weise ermöglichen.To produce a continuously reproducible punching image, such as the constant spacing of the perforations from each other, in one embodiment of the invention present invention, the office equipment along the guide rail arranged stop elements, which allow a determination of the sheet material in certain punching positions in a reproducible manner.
In einer weiteren Ausführungsform der vorliegenden Erfindung sind die Anschlagelemente so ausgebildet, dass sie in einer Anschlagstellung in den Bewegungsbereich der Stanzvorrichtung hineinragen und aus der Anschlagstellung aus dem Bewegungsbereich der Stanzvorrichtung in eine Freigabestellung bewegbar sind. Dadurch wird erreicht, dass die Stanzvorrichtung in den Stanzpositionen durch die Anschlagelemente an einer weiteren Fortbewegung innerhalb der Führungsschiene gehindert werden und nach dem Stanzvorgang weiterbewegt werden kann, wenn die Anschlagelemente in die Freigabestellung geschoben wurden. Dazu können die Anschlagelemente entweder vollständig aus dem Bewegungsbereich der Stanzvorrichtung herausgeführt werden oder aber so angeordnet werden, dass die Anschlagelemente nach Bewegung in die Freigabestellung von der Stanzvorrichtung überfahrbar sind.In a further embodiment of the present invention, the stop elements are designed so that they protrude in a stop position in the range of movement of the punching device and are movable from the stop position from the movement range of the punching device in a release position. This ensures that the punching device can be prevented in the punching positions by the stop elements on a further movement within the guide rail and can be moved after the punching operation when the stop elements have been pushed into the release position. For this purpose, the stop elements can either be completely led out of the range of movement of the punching device or arranged so that the stop elements are moved over after movement into the release position of the punching device.
Alternativ zum aktiven Herausbewegen der Anschlagelemente aus dem Bewegungsbereich der Stanzvorrichtung können in einem weiteren Ausführungsbeispiel die Anschlagelemente durch die Stanzvorrichtung nach Überwinden eines Widerstandes automatisch in die Freigabestellung bewegt werden. Dies kann beispielsweise dadurch erreicht werden, dass die Anschlagelemente in Richtung auf die Anschlagstellung federnd beaufschlagt sind.As an alternative to the active moving out of the stop elements from the range of movement of the punching device, in a further embodiment, the stop elements are automatically moved by the punching device after overcoming a resistance in the release position. This can be achieved, for example, by that the stop elements are resiliently acted upon in the direction of the stop position.
Eine besonders einfache Handhabung des Bürogerätes wird ermöglicht, indem die Anschlagelemente jeweils als zwischen Unterlage und Führungsschiene einerseits und der Stanzvorrichtung andererseits wirksame Rasteinrichtung ausgebildet sind. Dazu ist es vorteilhaft, wenn die Rasteinrichtung bei Bewegung der Stanzvorrichtung in einen Hohlraum unterhalb der Unterlage verschiebbar sind und nach einem Überfahren durch die Stanzvorrichtung in ihre Ausgangsposition zurückkehren.A particularly simple handling of the office appliance is made possible by the stop elements are each formed as between the pad and guide rail on the one hand and the punching device on the other hand effective latching device. For this purpose, it is advantageous if the latching device during movement of the punching device are displaceable in a cavity below the base and return to its starting position after passing over the punching device.
Die Rasteinrichtungen können einteilig beispielsweise über einen Steg in Form einer Wippe verbunden sein oder jeweils als separate Baueinheiten ausgebildet sein.The latching devices can be integrally connected, for example via a web in the form of a rocker or each be designed as separate units.
Um das Verschieben der Stanzvorrichtung innerhalb der Führungsschiene zu erleichtern, ist in einem Ausführungsbeispiel vorgesehen, die Anschlagelemente mit keilförmigen, abgeschrägten Kantenbereichen auszuführen. Dazu sind in einem bevorzugten Ausführungsbeispiel die Anschlagelemente im Berührungsbereich mit der Stanzvorrichtung pyramidenartig ausgebildet.In order to facilitate the displacement of the punching device within the guide rail, it is provided in one embodiment to carry out the stop elements with wedge-shaped, bevelled edge regions. For this purpose, in a preferred embodiment, the stop elements are formed in the contact area with the punching device pyramid-like.
Eine besonders platzsparende und bedienungsfreundliche Ausführungsform der vorliegenden Erfindung sieht vor, die Anschlagelemente innerhalb der Führungsschiene auszubilden. Natürlich können die Anschlagelemente auch derart oberhalb und/oder unterhalb der Führungsschiene angeordnet sein.A particularly space-saving and easy-to-use embodiment of the present invention provides to form the stop elements within the guide rail. Of course, the stop elements can also be like that be arranged above and / or below the guide rail.
In einem weiteren vorteilhaften Ausführungsbeispiel ist das erfindungsgemäße Bürogerät mit mindestens einer Schneideinrichtung versehen, über die das Blattwerk entlang und/oder senkrecht und/oder unter einem insbesondere verstellbaren Winkel relativ zum Anschlag beschneidbar ist. Dadurch wird es möglich, das zu bearbeitende Blattwerk in dem Bürogerät vollständig zu bearbeiten, ohne dazu das Blattwerk aus dem Bürogerät entfernen oder mehrfach ausrichten zu müssen, was mit einer Reduzierung der Fehlerquellen bei der Bearbeitung gleichzusetzen ist.In a further advantageous embodiment, the office device according to the invention is provided with at least one cutting device, via which the foliage along and / or perpendicular and / or under a particular adjustable angle relative to the stop can be curtailed. This makes it possible to completely edit the foliage to be processed in the office equipment without having to remove the foliage from the office equipment or align multiple times, which is equivalent to reducing the error sources in the editing.
Die Schneidrichtung kann beispielsweise als Hebelschneideinrichtung, als Klingenschneider oder auch als Rollenschneideinrichtung ausgeführt sein. Andere weitere Schneideinrichtungen, welche im Stand der Technik bekannt sind, können ebenfalls Verwendung finden.The cutting direction can be embodied, for example, as a lever cutting device, as a blade cutter or as a roller cutting device. Other other cutting devices known in the art may also be used.
In einem Ausführungsbeispiel der vorliegenden Erfindung ist neben der Schneideinrichtung ein Niederhalter zum Anpressen des Blattgutes auf die Blattgutauflage anzuordnen, wobei der Niederhalter zwischen einer angehobenen Ausgangsstellung und einer in Richtung auf die Unterlage versetzten Pressstellung bewegbar ist. Ein solcher Niederhalter ist beispielsweise in der
Nach einem weiteren Merkmal der Erfindung ist wie beispielsweise in der
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, noch bevorzugter um 12 mm. Alternativ dazu kann jedoch auch vorgesehen sein, dass die Schneideinrichtung im Bereich einer Stirnseite um eine horizontale Achse verschwenkbar gelagert ist, und zwar maximal um einen Winkel von 10°, vorzugsweise 4 bis 5°.In a further embodiment of the invention it is proposed that the guide rail in the region of their end faces is guided vertically displaceable, so that it can be raised and lowered parallel to the pad, and preferably by not more than 20 mm, more preferably by 12 mm. Alternatively, however, it can also be provided that the cutting device is mounted pivotably in the region of an end face about a horizontal axis, specifically at a maximum angle of 10 °, preferably 4 to 5 °.
Die Schneideinrichtung 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 Schneideinrichtung und Unterlage kann die Schneideinrichtung von Hand angehoben werden. Alternativ dazu besteht jedoch auch die Möglichkeit, dass die Schneideinrichtung ohne Betätigung mittels einer Feder in der Ausgangsstellung gehalten ist. Dies erleichtert das Durchschieben des Blattgutes durch den Spalt, erfordert allerdings das Niederdrücken 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 cutting device can be suspended so that it assumes the cutting position without actuation, in which the disc knife is seated on the base. For pushing through the sheet material through the gap between the cutting device and the base, the cutting device can be lifted by hand. Alternatively, however, there is also the possibility that the cutting device is held without actuation by means of a spring in the starting position. This facilitates the passage of the sheet material through the gap, however, requires the depression of the guide rail for the cutting process. Nevertheless, a clean cut also succeeds with this embodiment, because the depression of the guide rail with one hand and the displacement of the knife carriage can be done with the other hand, which is much easier to handle than in the known slitter, in which the knife carriage depressed and has to be moved at the same time.
Nach der Erfindung ist des weiteren vorgesehen, dass die Führungsschiene in 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 entgegensetzt. Dies erleichtert die Bedienung des Schneidgeräts.According to the invention, it is further provided that the guide rail can be fixed in its cutting position in its height-adjustable end (s) with a blocking device or blocking devices. In this way, the guide rail is fixed for the cutting process and can not move automatically or does not have to be depressed during the cutting process when a spring opposes. This facilitates the operation of the cutter.
Die bzw. jede Blockiereinrichtung ist vorzugsweise als Schnappeinrichtung ausgebildet, in die die Schneideinrichtung 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 designed as a snap device, in which the cutting device snaps automatically and unlockable when moving into the cutting position, so that the fixation of the guide rail is not connected in the cutting position with additional manipulations. Only for the unlocking process after the cutting operation of the snap device for the purpose of unlocking is necessary. For this purpose, the snap device may have an actuating slide, which is mounted in a favorable position.
Um die Abmessung des Blattgutes vor der Beschneidung bestimmen zu können, ist in einem Ausführungsbeispiel mindestens eine Messeinrichtung an dem Bürogerät vorgesehen. Die Messeinrichtungen können beispielsweise über einen Klappmechanismus an dem Bürogerät befestigt und durch ein Lineal oder ein Rollmessgerät gebildet sein.In order to be able to determine the dimension of the sheet material before the trimming, in one exemplary embodiment at least one measuring device is provided on the office appliance. The measuring devices can for example be attached to the office appliance via a folding mechanism and be formed by a ruler or a roll measuring device.

FIG. 4 ,
Die
Die Stanzvorrichtung 5 ist in eine parallel zum Anschlag 4 ausgerichtete Führungsschiene 6 eingesetzt und darin wie mit Pfeilen angezeigt verschiebbar gelagert, um Lochungen in das Blattgut 2 einzubringen, die jeweils einen gleichbleibenden Abstand zu dem an dem Anschlag 4 anliegenden Randbereich des Blattguts 2 aufweisen. Die Stanzvorrichtung 5 ist von der Führungsschiene 6 abnehmbar, wodurch eine flexiblere Gestaltung des Lochbildes beispielsweise durch Einsatz verschiedener Stanzgeräte mit unterschiedlichem Stanzbildern ermöglicht wird.The
Entlang der Führungsschiene 6 sind mehrere Anschlagelemente 7 vorgesehen, über die das Blattgut 2 reproduzierbar in der Stanzvorrichtung 5 positionierbar ist. Die Anschlagelemente 7 sind in gleichmäßigen Abständen zueinander innerhalb der Führungsschiene 6 angeordnet. Sie weisen einen zwischen der Unterlage 3 bzw. der Führungsschiene 6 einerseits und der Stanzvorrichtung 5 andererseits wirksamen Rastmechanismus 9 auf (siehe auch
In einer ersten Ausführungsform der vorliegenden Erfindung werden sämtliche Anschlagelemente 7 über eine gemeinsame Wippe gleichzeitig bei Überfahren von nur einem Anschlagelemente 7 durch die Stanzvorrichtung 5 gemeinsam in den Bereich unterhalb der Führungsschiene 6 verschwenkt. In einem weiteren alternativen Ausführungsbeispiel ist jedes einzelne Anschlagelement 7 separat mit einem eigenständigen Verschwenkmechanismus 9 versehen.In a first embodiment of the present invention, all stop
Die Anschlagelemente 7 sind im Berührungsbereich mit der Stanzvorrichtung 5 pyramidenartig ausgebildet und weisen zur leichteren Überwindung eines durch die Federkraft F erzeugten Widerstandes und damit einer leichteren Überfahrbarkeit durch die Stanzvorrichtung 5 keilförmig ausgebildete, abgerundete Kantenbereiche auf.The
Um nun Lochungen in das Blattgut 2 auf reproduzierbare Weise einbringen zu können, wird zunächst das Blattgut 2 in das Bürogerät 1 eingelegt und so lange in das Bürogerät 1 weiter eingeschoben, bis es am Anschlag 4 und/oder den Anschlagelementen 7 der Stanzvorrichtung 5 zur Anlage kommt. Die erste Lochung 12 wird eingebracht, wenn sich die Stanzvorrichtung 5 in einer ersten Endlage innerhalb der Führungsschiene 6 des Bürogerätes 1 befindet, indem ein Hebel 13 der Stanzvorrichtung 5 nach unten bewegt wird. Anschließend wird die Stanzvorrichtung 5 in Richtung des zweiten Endbereiches der Führungsschiene 6 so lange bewegt, bis sie eine zweite definierte Stanzposition erreicht hat.In order to be able to introduce perforations in the
Bei Erreichen der Stanzposition wird die Stanzvorrichtung 5 über nicht dargestellte Positionierelemente an einer Weiterbewegung gehindert, indem diese die Stanzeinrichtung 5 in ihrer Bewegung abbremsen oder anhalten. Anschließend kann durch erneutes Betätigen des Hebels 13 der Stanzeinrichtung 5 durch den Nutzer eine weitere Lochung 12 in das Blattgut 2 eingebracht werden. Dabei entspricht der Abstand der Lochungen 12 zueinander in diesem Ausführungsbeispiel genau den Abständen der einzelnen Positionierelemente.Upon reaching the punching position, the
In der
Die Schneideinrichtung 8 ist in diesem Ausführungsbeispiel vertikal verschieblich geführt und um 12 mm anhebbar, um das Einsetzen des Blattguts 4 in einen Spalt zwischen Führungsschiene 15 und Unterlage 2 zu vereinfachen.The cutting device 8 is guided vertically displaceable in this embodiment and can be raised by 12 mm to facilitate the insertion of the
Zum Schneiden des Blattguts 2 wird der Messerwagen 16 unter leichtem Druck innerhalb der Führungsschiene 15 verschoben, wobei das nicht dargestellte, darunter befindliche Scheibenmesser eine Drehbewegung ausführt und dabei das Blattgut 2 schneidet. Übrig bleibt nun das auf der Unterlage 3 ruhende, beschnitte Blattteil und das abgeschnittene Blattgutteil.For cutting the
Um die Länge des Kantenbereichs des Blattguts 2 senkrecht zur Schneidrichtung 17 festlegen zu können, ohne dazu eine weitere Verschiebung des Blattguts 2 innerhalb des Bürogerätes 1 durchführen zu müssen, sind in diesem Ausführungsbeispiel nicht dargestellte Führungsschienen in der Unterlage 2 ausgebildet, die es ermöglichen, die Schneideinrichtung 17 parallel zum Anschlag 4 zu verschieben und dadurch den Abstand zwischen Anschlag 4 und Schneideinrichtung 5 in reproduzierbarer Weise einstellen zu können und so je nach Bedarf zu verkleinern oder zu vergrößern.In order to be able to determine the length of the edge region of the
