This prevents tilting of this stack, even if it has a large height-width ratio, in particular the center of gravity of the stack in the shape with parallelogram-like cross-section is outside the base of the stack. If, after the cut, the cutting blade has been raised again, by advancing the sliding part in the direction of the cutting plane, the stack can be aligned with the remaining stack left on the other side of the cutting plane, specifically with the vertical plane facing the cutting plane, thus converting the cut stack into a parallelepipedal shape becomes.

This is to be seen against the background that when cutting the stack, acceleration forces act as the blade passes through the stack onto the blades, which are different. As a rule, therefore, there is no exact cross section representing a parallelogram.

Description

Die Vorrichtung findet insbesondere Verwendung bei einer Planschneidmaschine zum Schneiden von Papier, Pappe, Folien oder dergleichen. Hierbei wird ein zu schneidender Stapel, der auf einer horizontal angeordneten Tischfläche eines Tisches der Schneidmaschine aufliegt, mittels einer Vorschubeinrichtung unter einen Pressbalken und ein Schneidmesser vorgeschoben. Der Stapel wird mittels des Pressbalkens geklemmt und das Messer in vertikaler Ebene im ziehenden Schnitt durch den Stapel bewegt. Hierbei wird ein Stapel (auch als Nutzenstapel bezeichnet) vom Gesamtstapel abgetrennt. - Eine solche Schneidvorrichtung ist beispielsweise in der DE 31 01 911 C2 beschrieben.The device finds particular use in a planing machine for cutting paper, cardboard, foils or the like. Here, a stack to be cut, which rests on a horizontally arranged table surface of a table of the cutting machine, advanced by means of a feed device under a press bar and a cutting blade. The stack is clamped by means of the press beam and the knife is moved in a vertical plane in pulling section through the stack. In this case, a stack (also referred to as a benefit stack) is separated from the total stack. - Such a cutting device is for example in the DE 31 01 911 C2 described.

Aufgrund der keilförmigen Form des Messers, wobei das Messer auf seiner der Schneidebene abgewandeten Seite keilförmig von der Schneidebene weggerichtet ist, liegen die einzelnen Bogen des geschnittenen Stapels nach dem Ende des Schneidvorgangs derart aufeinander, dass der Stapel, in der Schneidebene gesehen, einen parallelogrammähnlichen Querschnitt aufweist. Diese Gestalt des Stapels nach dem Schnitt kann nicht nur aufgrund der keilförmigen Form des Messers bedingt sein, sondern auch dadurch, dass das Messer in einem Messerhalter gehalten ist und dieser Messerhalter beim Absenken in Richtung der Tischfläche die oberen Blattlagen des Stapels von der Schneidebene weg verschiebt, damit zum Überführen des Stapels in die Gestalt mit parallelogrammähnlichen Querschnitt beiträgt.Due to the wedge-shaped shape of the knife, the knife being directed wedge-shaped away from the cutting plane on its side facing away from the cutting plane, the individual sheets of the cut stack after the end of the cutting process to each other such that the stack, seen in the cutting plane, a parallelogram-like cross-section having. This shape of the stack after cutting may be due not only to the wedge shape of the knife, but also to the fact that the knife is held in a knife holder and this knife holder when lowering in the direction of the table surface shifts the upper sheet layers of the stack away from the cutting plane , thus contributes to the transfer of the stack in the shape with parallelogram-like cross-section.

Im Zusammenhang mit den Stützen des Stapels beim Schnitt, wenn dieser in die Gestalt mit parallelogrammähnlichen Querschnitt überführt wird, und im Zusammenhang mit dem Ausrichten des Stapels aus dieser Gestalt in eine quaderförmige Gestalt, findet ein sogenannter Nutzenwinkel Verwendung. Dieser wird manuell eingesetzt und weist eine Bodenplatte zur Auflage auf dem Tisch und eine mit der Bodenplatte verbundene und im spitzen Winkel zu dieser angeordnete Linealplatte auf. Der Winkel, den die Linealplatte mit der Tischoberfläche bei auf dieser aufliegender Bodenplatte einschließt, entspricht im Wesentlichen dem Winkel, den der parallelogrammähnlich verschobene Stapel auf seiner dem Nutzenwinkel zugewandten Seite mit diesem einschließt. Somit kann der Nutzenwinkel, dann, wenn er vor dem Abtrennen des Stapels unten an diesen angelegt ist, den Stapel beim Schnitt und damit dem Überführen in seine parallelogrammähnliche Gestalt stützen. Durch Schwenken der Linealplatte in ihre vertikale Position bezüglich der Tischoberfläche kann dann der Stapel mittels des Nutzenwinkels in seine quaderförmige Gestalt ausgerichtet werden. Ein solcher Nutzenwinkel ist in der DE 31 01 911 C2 beschrieben.In connection with the pillars of the stack when cut, when it is converted into the shape with parallelogram-like cross-section, and in connection with the alignment of the stack of this shape in a parallelepiped shape, a so-called benefit angle is used. This is used manually and has a base plate for resting on the table and connected to the bottom plate and arranged at an acute angle to this ruler plate. The angle that the ruler plate has with the table surface includes on this resting bottom plate substantially corresponds to the angle, which includes the parallelogram similar stack shifted on its side facing the utility angle with this. Thus, the benefit angle, when applied to the bottom of the stack prior to severing the stack, may support the stack in its parallell-like shape during cutting and thus transfer. By pivoting the ruler plate in its vertical position with respect to the table surface then the stack can be aligned by means of the benefit angle in its cuboid shape. Such a benefit angle is in the DE 31 01 911 C2 described.

In der DE 44 22 194 C1 ist ein Nutzenwinkel veranschaulicht, bei dem die Bodenplatte und die Linealplatte einen rechten Winkel zueinander einnehmen. Dieser Nutzenwinkel dient ausschließlich dem Ausrichten des Stapels, der in einer Gestalt mit parallelogrammähnlichem Querschnitt vorliegt, in eine quaderförmige Gestalt.In the DE 44 22 194 C1 illustrates a benefit angle in which the bottom plate and the ruler plate at right angles to each other. This benefit angle is used exclusively for aligning the stack, which is in a shape with parallelogram-like cross-section, in a cuboid shape.

In der Praxis ist es oftmals erforderlich, Stapel in eine Vielzahl kleiner Teilstapel zu trennen. Es müssen verhältnismäßig hohe, in Vorschubrichtung schmale Stapel kleiner Etiketten, Banderolen oder dergleichen geschnitten werden, wobei diese sicher zu handhaben sein sollen. Die Erstreckung der Stapel in Vorschubrichtung beträgt beispielsweise maximal 25 mm. Gerade bei derart schmalen Stapeln neigt der Stapel wegen des Überführens von der quaderförmigen Gestalt des Gesamtstapels in die Gestalt des abgeschnittenen Stapels mit parallelogrammähnlichem Querschnitt dazu, dass der abgeschnittene Stapel von der Schneidebene weg, senkrecht zu dieser kippt. Dies ist insbesondere dann kritisch, wenn Blätter zu schneiden sind, die eine glatte Oberfläche aufweisen bzw. mit einer glatten Oberfläche beschichtet sind, wie Etiketten oder Visitenkarten. Beim Schnitt verrutschen demnach die einzelnen Blätter zueinander. Dies ist für eine Weiterverarbeitung des abgeschnittenen Stapels nicht akzeptabel. Dies gilt insbesondere dann, wenn bei einem Schnitt mehrere Teilstapel, die senkrecht zur Schneidebene angeordnet sind, geschnitten werden, sodass bei diesem Schnitt entsprechend den mehreren Teilstapeln mehrere abgeschnittene Stapel nebeneinander anfallen, die jeweils eine Gestalt mit parallelogrammähnlichem Querschnitt aufweisen.In practice, it is often necessary to separate stacks into a plurality of small sub-stacks. It must be cut relatively high, narrow in the feed direction stack of small labels, bands or the like, which should be safe to handle. The extension of the stack in the feed direction is, for example, a maximum of 25 mm. Especially with such narrow stacks of the stack tends because of the transfer of the cuboid shape of the overall stack in the shape of the cut stack with parallelogram-like cross-section that the cut stack away from the cutting plane, perpendicular to this tilts. This is particularly critical when cutting sheets that have a smooth surface or are coated with a smooth surface, such as labels or business cards. In the cut, the individual leaves slip to each other. This is unacceptable for further processing of the trimmed stack. This is especially true if in a cut a plurality of sub-stacks, which are arranged perpendicular to the cutting plane, are cut, so that in this section corresponding to the plurality of sub-stacks several truncated stack next to each other, each having a shape with a parallelogram-like cross-section.

Um die genannte Problematik zu beherrschen, ist bereits gemäß der DE 40 13 352 A1 bei einer Schneidmaschine eine besondere maschinelle Zusatzeinrichtung vorgeschlagen worden, die die abzuschneidenden Stapel auf einem L-förmigen Lineal aufnimmt, wobei dieses Lineal den Stapel untergreift und auf der der Schneidebene abgewandten Seite des Stapels an diesem anliegt sowie beim Schnitt das Lineal schwenkt, sodass bei dem Schnitt der quaderförmige Stapel auf dem Lineal zu liegen kommt. Eine solche maschinelle Vorrichtung ist baulich und steuerungstechnisch sehr aufwendig.To master the mentioned problem, is already in accordance with the DE 40 13 352 A1 In a cutting machine, a special machine accessory has been proposed, which receives the stack to be cut on an L-shaped ruler, this ruler engages below the stack and on the side facing away from the cutting plane of the stack abuts this and the section pivots the ruler, so in the Cut the cuboid pile on the ruler comes to rest. Such a mechanical device is structurally and control technology very expensive.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so weiterzubilden, dass ein Stapel mit einem großen Höhen-Breiten-Verhältnis bei dessen Überführung in eine Gestalt mit parallelogrammähnlichem Querschnitt am Kippen gehindert wird und eine einfache Ausrichtung des Stapels aus dieser Gestalt in eine quaderförmige Gestalt möglich ist.The object of the invention is to provide a device of the type mentioned in such a way that a stack with a large height-width ratio is prevented in its transfer to a shape with parallelogram cross-section on tilting and a simple orientation of the stack of this shape in a cuboid shape is possible.

Zur Lösung dieser Aufgabe ist die Vorrichtung der eingangs genannten Art gekennzeichnet durch ein kammartiges Stützteil mit Kammschlitzen und mit einer ebenen Stützfläche, die unter einem spitzen Winkel zur Horizontalen und unter einem spitzen Winkel zur Vertikalen angeordnet ist, sowie durch ein Schiebeteil mit parallel angeordneten Vorsprüngen, deren freien Enden in einer vertikalen Ebene angeordnet sind, die eine Ausrichtebene bildet, wobei beim horizontalen Verschieben des Schiebeteils senkrecht zur Ausrichtebene zum Ausrichten des Stapels die Vorsprünge die Kammschlitze durchsetzen.To solve this problem, the device of the type mentioned is characterized by a comb-like support member with comb slots and with a flat support surface which is disposed at an acute angle to the horizontal and at an acute angle to the vertical, and by a sliding part with parallel projections, the free ends of which are arranged in a vertical plane which forms an alignment plane, wherein upon horizontal displacement of the sliding part perpendicular to the alignment plane for aligning the stack, the projections pass through the comb slots.

Die Angaben "horizontal" und "vertikal" beziehen sich darauf, dass bei einer Schneidmaschine, in deren Zusammenhang die erfindungsgemäße Vorrichtung Verwendung findet, die Tischebene der Schneidmaschine zur Aufnahme des zu schneidenden Stapels horizontal angeordnet ist und die Schneidebene des Messers vertikal angeordnet ist. Demnach sind die Blätter, die den Stapel bilden, horizontal angeordnet und liegen aufeinander.The terms "horizontal" and "vertical" refer to the fact that in a cutting machine, in the context of the device according to the invention is used, the cutting plane of the cutting machine for receiving the stack to be cut is arranged horizontally and the cutting plane of Knife is arranged vertically. Accordingly, the leaves that make up the stack are arranged horizontally and lie against each other.

Wesentlich ist bei der erfindungsgemäßen Vorrichtung somit, dass sie zwei funktionelle Bauteile aufweist, wobei das eine funktionelle Bauteil das kammartige Stützteil ist, das aufgrund der Ausbildung der ebenen Stützfläche dem Abstützen des beim Schnitt vom Gesamtstapel abgetrennten Stapels dient, der beim Schnitt in die Gestalt mit parallelogrammähnlichem Querschnitt überführt wird. Das andere funktionelle Bauteil ist das Schiebeteil, das relativ zum Stützteil verfahren werden kann, wobei beim Verfahren des Schiebeteils die freien Enden der Vorsprünge des Schiebeteils, die eine vertikale Ebene bilden, zunehmend die Kammschlitze durchsetzen und in Kontakt mit dem Stapel gelangen und mit zunehmendem Verschieben des Schiebeteils in Richtung des Stapels dieser an der Ausrichtebene des Schiebeteils ausgerichtet und damit in die quaderförmige Gestalt überführt wird.It is essential in the device according to the invention thus that it has two functional components, wherein the one functional component is the comb-like support member, which serves to support the cut of the total stack separated stack due to the formation of the flat support surface, which in the cut in the shape parallelogram-like cross section is transferred. The other functional component is the sliding part, which can be moved relative to the support part, wherein in moving the sliding part, the free ends of the projections of the sliding part, which form a vertical plane, increasingly pass through the comb slits and come into contact with the stack and with increasing displacement the sliding part is aligned in the direction of the stack of this on the alignment plane of the sliding part and thus converted into the cuboid shape.

Bei bezüglich des Stützteils zurückgezogenem Schiebeteil wird das Stützteil in seinem unteren Bereich an den Gesamtstapel angelegt, sodass beim Schnitt der abgeschnittene Stapel, der hierbei in die Gestalt mit parallelogrammähnlichem Querschnitt überführt wird, von der ebenen Stützfläche des Stützteils abgestützt wird. Dies verhindert ein Kippen dieses Stapels, auch dann, wenn er ein großes Höhen-Breiten-Verhältnis aufweist, insbesondere der Schwerpunkt des Stapels in der Gestalt mit parallelogrammähnlichem Querschnitt außerhalb der Grundfläche des Stapels liegt. Ist nach dem Schnitt das Schneidmesser wieder angehoben, kann durch Vorschieben des Schiebeteils in Richtung der Schneidebene der Stapel an dem auf der anderen Seite der Schneidebene verbliebenen Reststapel, konkret dessen der Schneidebene zugewandten vertikalen Fläche ausgerichtet werden, womit der abgeschnittene Stapel in eine quaderförmige Gestalt überführt wird. Ein solches Ausrichten des Stapels kann alternativ an einem auf der der Vorrichtung abgewandten Seite des Stapels anzuordnenden, vertikalen Lineal erfolgen. Ein solches ist beispielsweise in der DE 31 01 911 C2 beschrieben ist.With respect to the support member retracted sliding part, the support member is applied in its lower portion to the entire stack, so that when cut the cut stack, which is in this case converted into the shape with parallelogram-like cross-section, is supported by the flat support surface of the support member. This prevents tilting of this stack, even if it has a large height-width ratio, in particular the center of gravity of the stack in the shape with parallelogram-like cross-section is outside the base of the stack. If, after the cut, the cutting blade has been raised again, by advancing the sliding part in the direction of the cutting plane, the stack can be aligned with the remaining stack left on the other side of the cutting plane, specifically with the vertical plane facing the cutting plane, thus converting the cut stack into a parallelepipedal shape becomes. Such an alignment of the stack can alternatively take place on a vertical ruler to be arranged on the side of the stack facing away from the device. Such is for example in the DE 31 01 911 C2 is described.

Das Schiebeteil kann manuell oder maschinell verschoben werden. Bei manueller Verschiebung des Schiebeteils wird es als vorteilhaft angesehen, wenn dieses auf dessen der Ausrichtebene abgewandten Seite mit einem Handgriff versehen ist. Bei maschinell verschieblicher Ausbildung des Schiebeteils sind Stellmittel zum Verschieben des Schiebeteils in Richtung der Schneidebene und von dieser weg vorgesehen.The sliding part can be moved manually or mechanically. With manual displacement of the sliding part, it is considered advantageous if this is provided on its side facing away from the alignment plane with a handle. In mechanically displaceable design of the sliding part adjusting means are provided for moving the sliding part in the direction of the cutting plane and away from it.

Bei der Vorrichtung entspricht der spitze Winkel, den die ebene Stützfläche des kammartigen Stützteils zur Vertikalen einschließt, im Wesentlichen dem Keilwinkel des Schneidmessers der Planschneidmaschine oder dem Keilwinkel einer Messeraufnahme für das Schneidmesser der Planschneidmaschine. Nach dem Schnitt ist somit die der Vorrichtung zugewandte Seite des abgeschnittenen Stapels im Wesentlichen parallel zur ebenen Stützfläche des kammartigen Stützteils angeordnet.In the apparatus, the acute angle included by the planar support surface of the comb-like support member relative to the vertical substantially corresponds to the wedge angle of the cutting blade of the planing machine or the wedge angle of a knife holder for the cutting blade of the planing machine. After the cut, the side of the cut stack facing the device is thus arranged essentially parallel to the flat support surface of the comb-like support part.

Unter parallelogrammähnlichem Querschnitt wird ein solcher verstanden, der nicht streng parallelogrammförmig ist. Dies ist vor dem Hintergrund zu sehen, dass beim Schneiden des Stapels Beschleunigungskräfte beim Durchtritt des Schneidmessers durch den Stapel auf die Blätter wirken, die unterschiedlich sind. Im Regelfall ergibt sich somit kein exakter Querschnitt, der ein Parallelogramm darstellt.A parallelogram-like cross-section is understood to mean one which is not strictly parallelogram-shaped. This is to be seen against the background that when cutting the stack, acceleration forces act as the blade passes through the stack onto the blades, which are different. As a rule, therefore, there is no exact cross section representing a parallelogram.

Baulich besonders einfach ist das Stützteil gestaltet, wenn es als Platte ausgebildet ist, die die Kammschlitze aufweist. Vorzugsweise bilden das Stützteil und ein Bodenteil, das insbesondere als Bodenplatte ausgebildet ist, eine Baueinheit. Die Bodenplatte ist horizontal angeordnet und das Stützteil ist im spitzen Winkel zur Bodenplatte angeordnet. Bei der genannten Baueinheit kann es sich um eine konstruktive oder aber um eine funktionelle Baueinheit handeln.Structurally particularly simple, the support member is designed when it is designed as a plate having the comb slots. Preferably, the support member and a bottom part, which is designed in particular as a bottom plate, form a structural unit. The bottom plate is arranged horizontally and the support member is arranged at an acute angle to the bottom plate. The structural unit mentioned can be a constructive or else a functional structural unit.

Vorzugsweise bilden das Schiebeteil und eine vertikal angeordnete Lagerplatte eine Baueinheit. Die Lagerplatte ist auf der der Ausrichtebene des Schiebeteils abgewandten Seite der Vorsprünge mit diesen verbunden. Auch bei dieser genannten Baueinheit kann es sich um eine bauliche oder funktionelle Einheit handeln.Preferably, the sliding part and a vertically arranged bearing plate form a structural unit. The bearing plate is on the alignment plane of the sliding part opposite side of the projections connected to these. Also in this named unit may be a structural or functional unit.

Die Vorsprünge des Schiebeteils sind insbesondere als vertikal angeordnete, parallel zueinander angeordnete Platten ausgebildet. Hierdurch ergibt sich eine baulich besonders einfache Gestaltung des Schiebeteils.The projections of the sliding part are formed in particular as vertically arranged, mutually parallel plates. This results in a structurally particularly simple design of the sliding part.

Ist eine manuelle Betätigung des Schiebeteils vorgesehen, weist das Schiebeteil vorzugsweise einen mit der Lagerplatte verbundenen Handgriff auf.If a manual actuation of the sliding part is provided, the sliding part preferably has a handle connected to the bearing plate.

Die Vorsprünge des Schiebeteils liegen insbesondere auf der Bodenplatte auf.The projections of the sliding part are in particular on the bottom plate.

Gemäß einer baulich besonders vorteilhaften Weiterbildung der Vorrichtung ist vorgesehen, dass die Erstreckung von Lagerplatte und Stützteil, in der Ausrichtebene und in Breitenerstreckung der Kammschlitze betrachtet, gleich ist, zumindest im Wesentlichen gleich ist. Dadurch ergibt sich eine definierte Arbeitsbreite der Vorrichtung aufgrund der Abmessungen von Lagerplatte und Stützteil, somit indirekt von Schiebeteil und Stützteil.According to a structurally particularly advantageous embodiment of the device, it is provided that the extent of the bearing plate and the support part, viewed in the alignment plane and in the width extension of the comb slits, is the same, at least substantially the same. This results in a defined working width of the device due to the dimensions of the bearing plate and the support member, thus indirectly by sliding part and support member.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass sie eine Aufnahme mit plattenförmigen Boden und senkrecht zum Boden sowie parallel zueinander angeordnete Seitenwände aufweist, zur Aufnahme des Stützteils und des Schiebeteils, insbesondere der das Stützteil aufweisenden Baueinheit und der das Schiebeteil aufweisenden Baueinheit, zwischen den Seitenwänden.According to a preferred embodiment of the invention it is provided that it has a receptacle with plate-shaped bottom and perpendicular to the bottom and mutually parallel side walls, for receiving the support member and the sliding part, in particular of the support member having assembly and the sliding part having assembly between the sidewalls.

Die Aufnahme bildet somit einen räumlichen Bereich der Vorrichtung, der mit dem Stützteil und Schiebeteil zusammenwirkt und der Aufnahme des geschnittenen Stapels bzw. mehrerer nebeneinander angeordneter oder sogar mehrere nebeneinander und voreinander angeordneter Stapel dient. Diese mehreren voreinander angeordneten Stapel werden bei mehreren Schnitten erzeugt. Es ist somit nicht erforderlich, unmittelbar nach einem Schnitt den bzw. die abgeschnittenen Stapel zu entfernen, sondern es können weitere Schnitte vollführt werden, bevor die erzeugten Stapel abtransportiert werden. Nach jedem Schnitt oder aber nach mehreren Schnitten kann das Ausrichten der erzeugten Stapel mittels der Vorrichtung erfolgen.The receptacle thus forms a spatial region of the device which interacts with the support part and sliding part and serves to receive the cut stack or a plurality of juxtaposed or even several stacks arranged next to one another and in front of one another. These multiple stacked stacks are created in multiple cuts. It Thus, it is not necessary to remove the cut pile or stacks immediately after a cut, but further cuts can be made before the stacks produced are removed. After each cut or after several cuts, the alignment of the stacks produced can be done by means of the device.

Die Erstreckung von Lagerplatte und Stützteil ist insbesondere so gewählt, dass diese, in Ausrichtebene und in Breitenerstreckung der Kammschlitze, geringfügig geringer ist als der Abstand der beiden Seitenwände. Hierdurch wird die Lagerplatte und das Stützteil in einer Bewegungsrichtung senkrecht zur Schneidebene durch die beiden Seitenwände der Aufnahme geführt.The extension of the bearing plate and the support member is particularly chosen so that it, in the alignment plane and in width extension of the comb slots, is slightly smaller than the distance between the two side walls. As a result, the bearing plate and the support member is guided in a direction perpendicular to the cutting plane through the two side walls of the recording.

Als besonders vorteilhaft wird es angesehen, wenn die obere Fläche des plattenförmigen Bodens eine Ebene mit einer horizontalen Tischoberfläche der Schneidmaschine unterhalb des Schneidmessers der Schneidmaschine bildet. Demzufolge kann mittels einer Vorschubeinrichtung der Schneidmaschine das zu schneidende Gut bis auf den plattenförmigen Boden vorgeschoben werden, der mit seiner oberen Fläche die Ebene mit der horizontalen Tischoberfläche der Schneidmaschine bildet.It is considered particularly advantageous if the upper surface of the plate-shaped bottom forms a plane with a horizontal table surface of the cutting machine below the cutting blade of the cutting machine. Accordingly, by means of a feed device of the cutting machine, the material to be cut can be advanced to the plate-shaped bottom, which forms with its upper surface the plane with the horizontal table surface of the cutting machine.

Die Vorrichtung besteht insbesondere aus Kunststoff.The device consists in particular of plastic.

Die grundsätzlich in den Fig. 1 und 2 veranschaulichte erfindungsgemäße Vorrichtung 1 weist ein Stützteil 2 und ein Bodenteil 3 auf, die eine Baueinheit bilden, ferner ein Schiebeteil 4 und eine Lagerplatte 5 auf, die gleichfalls eine Baueinheit bilden. Die beiden Baueinheiten sind von Hand relativ zueinander verschiebbar.The principle in the Fig. 1 and 2 illustrated inventive device 1 comprises a support member 2 and a bottom part 3, which form a structural unit, further comprising a sliding part 4 and a bearing plate 5, which also form a structural unit. The two units are manually displaceable relative to each other.

Im Detail ist das Stützteil 2 kammartig mit Kammschlitzen 6 ausgebildet und es weist das Stützteil 2 eine ebene Stützfläche 7 auf. Diese ist unter einem spitzen Winkel zur Horizontalen und unter einem spitzen Winkel zur Vertikalen angeordnet.In detail, the support member 2 is formed comb-like with comb slots 6 and it has the support member 2 has a flat support surface 7. This is arranged at an acute angle to the horizontal and at an acute angle to the vertical.

Das Schiebeteil 4 ist mit parallel angeordneten Vorsprüngen 8 versehen, deren freie Enden 9 in einer vertikalen Ebene angeordnet sind, die eine Ausrichtebene 10 bildet. Beim horizontalen Verschieben des Schiebeteils 4 senkrecht zur Ausrichtebene 10 durchsetzen die Vorsprünge 8 die Kammschlitze 6.The sliding part 4 is provided with parallel projections 8, the free ends 9 are arranged in a vertical plane which forms an alignment plane 10. During horizontal displacement of the sliding part 4 perpendicular to the alignment plane 10, the projections 8 pass through the comb slots 6.

Das Stützteil 2 ist als Platte ausgebildet, die die Kammschlitze 6 aufweist. Das Bodenteil 3 ist als Bodenplatte ausgebildet. Das Bodenteil 3 ist horizontal angeordnet und es ist das Stützteil 2 im spitzen Winkel zum Bodenteil 3 angeordnet.The support member 2 is formed as a plate having the comb slots 6. The bottom part 3 is formed as a bottom plate. The bottom part 3 is arranged horizontally and it is the support member 2 at an acute angle to the bottom part 3 is arranged.

Die Lagerplatte 5 ist auf der der Ausrichtebene 10 des Schiebeteils 4 abgewandten Seite der Vorsprünge 8 mit diesen verbunden. Die Vorsprünge 8 sind als vertikal angeordnete, parallel zueinander angeordnete Platten ausgebildet. Das Schiebeteil 4 ist auf dessen der Ausrichtebene 10 abgewandten Seite mit einem Handgriff 11 versehen, der mit der Lagerplatte 5 verbunden ist. Die Erstreckung von Lagerplatte 5 und Stützteil 2 ist, in der Ausrichtebene 10 und in Breitenerstreckung der Kammschlitze 6 gleich, zumindest im Wesentlichen gleich.The bearing plate 5 is connected to the aligning plane 10 of the sliding part 4 opposite side of the projections 8 with these. The projections 8 are formed as vertically arranged, mutually parallel plates. The sliding part 4 is provided on the side facing away from the alignment plane 10 with a handle 11 which is connected to the bearing plate 5. The extension of the bearing plate 5 and the support part 2 is, in the alignment plane 10 and in widthwise extension of the comb slots 6 equal, at least substantially equal.

Die Vorrichtung weist eine Aufnahme 12 mit plattenförmigen Boden 13 und senkrecht zum Boden 13 sowie parallel zueinander angeordneten Seitenwänden 14 auf, zwecks Aufnahme der beiden Baueinheiten, die das Stützteil 2 und das Schiebeteil 4 aufweisen. Die beiden Baueinheiten sind hierbei zwischen den Seitenwänden 14 aufgenommen. Die Erstreckung von Lagerplatte 5 und Stützteil 2, in der Ausrichtebene 10 und in Breitenerstreckung der Kammschlitze 6 gesehen, ist geringfügig geringer als der Abstand der beiden Seitenwände 14. Das mit dem Stützteil 2 verbundene Bodenteil 3 liegt auf dem Boden 13 auf und es liegen die Vorsprünge 8 auf dem Bodenteil 3 auf. Vorzugsweise bestehen zumindest die beiden Baueinheiten, die das Stützteil 2 und das Schiebeteil 4 aufweisen, aus Kunststoff. Auch die Aufnahme 12 kann aus Kunststoff bestehen, oder aus Metall. Bei Verwendung von Metall ist der Vorteil zu verzeichnen, dass die Aufnahme 12 eine geringere Wandstärke, insbesondere im Bereich des Bodens 13 aufweisen kann.The device has a receptacle 12 with a plate-shaped bottom 13 and perpendicular to the bottom 13 and mutually parallel side walls 14, for receiving the two units, which have the support member 2 and the sliding part 4. The two units are in this case added between the side walls 14. The extension of the bearing plate 5 and support member 2, seen in the alignment plane 10 and in width extension of the comb slots 6, is slightly smaller than the distance between the two side walls 14. The connected to the support part 2 bottom part 3 rests on the floor 13 and it is the Projections 8 on the bottom part 3. Preferably, at least the two structural units, which have the support part 2 and the sliding part 4, made of plastic. The receptacle 12 may be made of plastic, or metal. When using metal, the advantage can be seen that the receptacle 12 may have a smaller wall thickness, in particular in the region of the bottom 13.

Die erfindungsgemäße Vorrichtung findet Verwendung im Zusammenhang mit der in den Fig. 3 bis 7 veranschaulichten Planschneidmaschine 15. Diese weist einen Tisch 16 mit horizontal angeordneter Tischoberfläche 17 auf. Der Tisch 16 dient im Bereich der Tischoberfläche 17 der Aufnahme von gestapeltem Blattgut aus Papier, Pappe, Folie und dergleichen. Mittels der Schneidmaschine 15 wird der Stapel bzw. werden Stapel in Teilstapel geschnitten, die der Einfachheit halber gleichfalls als Stapel bezeichnet sind.The device according to the invention finds use in connection with the in the Fig. 3 to 7 illustrated plan cutting machine 15. This has a table 16 with horizontally arranged table surface 17. The table 16 is used in the area of the table surface 17 of the recording of stacked Sheet material of paper, cardboard, foil and the like. By means of the cutting machine 15, the stack or stacks are cut into partial stacks, which are also referred to as stack for the sake of simplicity.

In bekannter Art und Weise ist die Planschneidmaschine 15 mit einem Schneidmesser 18, einem Messerhalter 19, einem Pressbalken 20 und einem Vorschubsattel 21 versehen. Mittels eines Vorschubsattels 21 wird ein zu schneidender Stapel 22 unter das Schneidmesser 18 vorgeschoben und mittels des Pressbalkens 20 zwischen diesem und dem Tisch 16 geklemmt. Benachbart dem Pressbalken 20 ist das Schneidmesser 18 angeordnet, das beim Niedergang des Messerhalters 19 und damit des Schneidmessers 18 einen Teilstapel - Stapel 23 - abtrennt, sodass ein Reststapel 24, der dann den anschließend zu schneidenden Stapel bildet, verbleibt.In a known manner, the planing machine 15 is provided with a cutting blade 18, a knife holder 19, a pressing beam 20 and a feed saddle 21. By means of a feed saddle 21, a stack to be cut 22 is advanced under the cutting blade 18 and clamped by means of the press beam 20 between this and the table 16. Adjacent to the pressing beam 20, the cutting blade 18 is arranged, which at the decline of the knife holder 19 and thus of the cutting blade 18 a partial stack - stack 23 - separates, so that a residual stack 24, which then forms the subsequently to be cut stack remains.

Die Schneidebene des Schneidmessers 18 ist mit der Bezugsziffer 25 bezeichnet. Das Schneidmesser 18 ist im Bereich seines unteren Endes keilförmig ausgebildet. Das Keilende 26 des Schneidmessers 18 weist einen spitzen Winkel auf, mit vertikaler Fläche, die mit der Schneidebene 25 zusammenfällt und geneigter Fläche auf der der Schneidebene 25 abgewandten Seite des Schneidmessers 18. Auch der Messerhalter 18 ist im Bereich seines unteren Endes keilförmig ausgebildet. Die Keilform von Schneidmesser 18 und Messerhalter 19 führt dazu, dass beim Abtrennen des Stapels 23 dieser in sich verschoben wird und damit, wie der Darstellung der Fig. 6 zu entnehmen ist, in eine Gestalt überführt wird, die einen parallelogrammähnlichen Querschnitt aufweist. In dieser Figur ist der Querschnitt exakt als Parallelogramm dargestellt.The cutting plane of the cutting blade 18 is designated by the reference numeral 25. The cutting blade 18 is wedge-shaped in the region of its lower end. The wedge end 26 of the cutting blade 18 has an acute angle, with a vertical surface which coincides with the cutting plane 25 and inclined surface on the side facing away from the cutting plane 25 side of the cutting blade 18. The knife holder 18 is wedge-shaped in the region of its lower end. The wedge shape of the cutting blade 18 and knife holder 19 causes the separation of the stack 23 of this is moved in and thus, as the representation of Fig. 6 can be seen, is converted into a shape that has a parallelogram-like cross-section. In this figure, the cross section is shown exactly as a parallelogram.

Die erfindungsgemäße Vorrichtung 1 findet insbesondere Verwendung für den Fall, dass mittels der Planschneidmaschine 15 Stapel 25 erzeugt werden, die ein großes Höhen-Breiten-Verhältnis aufweisen. Die Höhe des Stapels 23 ist somit um ein Mehrfaches größer als die Erstreckung des Stapels in Vorschubrichtung X des Vorschubsattels 21. Hiermit verbunden ist die Gefahr, dass der Stapel 23 kippt, insbesondere deshalb, weil dessen Schwerpunkt außerhalb der Kontaktfläche des Stapels 23 mit dessen Unterlage ist. In den Figuren ist aus Gründen besserer Darstellung kein großes Höhen-Breiten-Verhältnis des Stapels 23 veranschaulicht.The device 1 according to the invention finds particular use in the case where by means of the plan cutting machine 15 stacks 25 are generated which have a large height-width ratio. The height of the stack 23 is thus greater by a multiple than the extension of the stack in the feed direction X of the feed saddle 21. This is associated with the risk that the Stack 23 tilts, in particular because its center of gravity is outside the contact surface of the stack 23 with its base. In the figures, for reasons of better illustration, no large height-width ratio of the stack 23 is illustrated.

Wie insbesondere der Darstellung der Fig. 5 zu entnehmen ist, ist der Tisch 16 zweiteilig ausgebildet und weist, bezogen auf den Vorschubsattel 21, auf der der Schneidebene 25 abgewandten Seite angeordnetes Tischteil 27 auf, das parallel absenkbar ist. Das Tischteil 27 wird um die Stärke des Bodens 13 der Aufnahme 12 abgesenkt, sodass die obere Fläche 28 des plattenförmigen Bodens 13 eine Ebene mit der Tischoberfläche 17 im verbleibenden Bereich des Tisches 16 bildet.As in particular the representation of the Fig. 5 can be seen, the table 16 is formed in two parts and has, based on the feed saddle 21, on the side facing away from the cutting plane 25 side arranged table part 27 which is lowered in parallel. The table part 27 is lowered by the thickness of the bottom 13 of the receptacle 12, so that the upper surface 28 of the plate-shaped bottom 13 forms a plane with the table surface 17 in the remaining area of the table 16.

Wie der Darstellung der Fig. 3 und 5 zu entnehmen ist, wird der Stapel 22 mittels des Vorschubsattels 21 vorgeschoben, bis über die Schneidebene 25 hinaus, wobei in der Realität der Stapel 22 über eine wesentlich kleinere Strecke als dargestellt über die Schneidebene 25 hinausgeschoben wird, um das genannte große Höhen-Breiten-Verhältnis des abzuschneidenden Stapels zu erreichen. Es wird dann, bei Anordnung der Vorrichtung 1 gemäß der Darstellung in Fig. 1 die Vorrichtung 1 so am zu schneidenden Stapel 22 positioniert, dass das Schiebeteil 4 mit seinen Vorsprüngen 8 am Stapel 22 anliegt. Dann erfolgt der Schnitt. Unter diesem Aspekt wird der Pressbalken 20 auf den Stapel 22 abgesenkt und das Schneidmesser 18 niedergefahren, womit der Stapel 23 erzeugt wird, der wegen der Keilform von Schneidmesser 18 und Messerhalter 19 in der Gestalt mit parallelogrammähnlichem Querschnitt vorliegt. Bei Schneiden des Stapels 22 und damit Überführen des erzeugten Stapels 23 in die Parallelogrammform, gemäß der Darstellung in den Fig. 4 und 6, wird über den Stapel 23 das Schiebeteil 4 von der Schneidebene 25 weg verfahren bis hinter die Stützfläche 7 des Stützteils verfahren und es liegt der Stapel 23 am Stützteil 2, konkret der geneigten, ebenen Stützfläche 7 des Stützteils 2 an. Unter diesem Aspekt entspricht der spitze Winkel der ebenen Stützfläche 7 zur Vertikalen im Wesentlichen dem Keilwinkel des Schneidmessers 18 bzw. dem Keilwinkel des Messerhalters 19.As the representation of Fig. 3 and 5 can be seen, the stack 22 is advanced by means of the feed saddle 21, to beyond the cutting plane 25 out, in reality, the stack 22 is pushed over a much smaller distance than shown on the cutting plane 25 to the said large height-width To achieve ratio of the stack to be cut off. It is then, in the arrangement of the device 1 as shown in FIG Fig. 1 the device 1 is positioned on the stack to be cut 22 so that the sliding part 4 rests with its projections 8 on the stack 22. Then the cut takes place. In this aspect, the press beam 20 is lowered onto the stack 22 and the cutting blade 18 is lowered, thus producing the stack 23 which is in the shape of a parallelogram-like cross section due to the wedge shape of the cutting blade 18 and knife holder 19. When cutting the stack 22 and thus transferring the generated stack 23 in the Parallelogrammform, as shown in the Fig. 4 and 6 , is moved over the stack 23, the sliding part 4 of the cutting plane 25 away to behind the support surface 7 of the support member and it is the stack 23 on the support member 2, specifically the inclined, flat support surface 7 of the support member 2 at. In this aspect, the acute angle of the flat support surface 7 corresponds to Vertical substantially the wedge angle of the cutting blade 18 and the wedge angle of the knife holder 19th

Nach dem Schnitt fährt das Schneidmesser 18 wieder nach oben und es kann dann durch Verfahren des Schiebeteils 4 und damit Kontakt der freien Enden der Vorsprünge 8 des Schiebeteils 4 in Richtung der Schneidebene 25 der Stapel 23 in seine in den Fig. 3 und 7 veranschaulichte quaderförmige Gestalt ausgerichtet werden. Diese Ausrichtung erfolgt an der vertikalen benachbarten Fläche des auf dem Tisch 16 befindlichen Reststapels 24.After cutting the cutting blade 18 moves back up and then it can by moving the sliding part 4 and thus contact the free ends of the projections 8 of the sliding part 4 in the direction of the cutting plane 25 of the stack 23 in his in the Fig. 3 and 7 illustrated cuboid shape to be aligned. This alignment takes place on the vertical adjacent surface of the rest stack 24 located on the table 16.

Die erfindungsgemäße Vorrichtung 1 verhindert beim Erzeugen des Stapels 23 ein Kippen des Stapels und ermöglicht überdies das Ausrichten des parallelogrammförmig vorliegenden Stapels 23. Darüber hinaus ermöglicht die Ausbildung der Aufnahme 12 der Vorrichtung 1, dass diese eine Vielzahl von Stapeln 23 nebeneinander, somit in Richtung der Schneidebene 25 gesehen, als auch hintereinander, somit senkrecht zur Schneidebene 25 gesehen, aufnehmen kann. Nebeneinander fallen eine Vielzahl von Stapeln 23 an, wenn mittels des Vorschubsattels 21 mehrere nebeneinander angeordnete Stapel 22 vorgeschoben werden. Hintereinander fallen die Stapel 23 an, wenn mittels der Aufnahme 12 Stapel 23, die aufgrund mehrerer Messerschnitte erzeugt sind, aufzunehmen sind. Die Aufnahme 12 ermöglicht es, diese Stapel 23 zu sammeln und auf dem Boden 13 der Aufnahme 12 angeordnet der Weiterverarbeitung zuzuführen, indem beispielsweise die Aufnahme 12 als solche, zusammen mit den Stapeln 23 zu einer Weiterverarbeitungsstation gebracht wird.The inventive device 1 prevents when producing the stack 23, a tilting of the stack and also allows the alignment of the parallelogram stack present 23. In addition, the formation of the receptacle 12 of the device 1, that this a plurality of stacks 23 side by side, thus in the direction of Cutting plane 25 seen, as well as one behind the other, thus seen perpendicular to the cutting plane 25, can record. Next to each other fall a plurality of stacks 23, if by means of the feed saddle 21 a plurality of juxtaposed stack 22 are advanced. The stacks 23 fall in succession when, by means of the receptacle 12, stacks 23, which are produced on the basis of several knife cuts, are to be received. The receptacle 12 makes it possible to collect these stacks 23 and arranged on the bottom 13 of the receptacle 12 for further processing, for example by taking the receptacle 12 as such, together with the stacks 23, to a further processing station.
