- a device for a sheet punching and embossing machine is known.
- the support plate is clamped by means of adjusting and retaining screws and roughly aligned.
- the Felneinwolf then takes place via the adjustment of stops in the mounting frame of the support plate.

- the invention has for its object to provide a device for punching benefits from sheets for a sheet punching and embossing a Bogenstanz- and To create embossing machine that allows minimal design means a reduction of set-up times with the highest repeatability and at the same time is able to compensate for pressure fluctuations in the hydraulic system.
- the pressure in the hydraulic system is constructed by a piston which is supported by a mechanical spring on a ve constitue clamping screw. Due to the inventive hydraulic clamping of the support plate eliminates a mechanical clamping on adjusting and retaining screws, so that the support plate for positioning and fixation in the frame only needs to be inserted by the operator. During insertion of the support plate in the frame positioning is done via a cylinder pin attached to the frame after the support plate is fixed by means of a successive pressure build-up in the hydraulic system. Since only the pressure on the hydraulic system must be applied by the operator, the manual alignment within the frame is completely eliminated, so that the set-up time is substantially reduced.
- FIG. 1 the basic structure of a sheet punching and embossing machine 1 for punching, breaking and depositing sheets of paper, cardboard and the like is shown.
- the punching and embossing machine 1 consists of a punching device 2, a breakout device 3 and a depositing device 4, which are supported and enclosed by a common machine housing 5.
- the sheets 6 are gripped by mounted on rotating chains 7 rapiers 8 at its front edge and intermittently pulled through the various stations 2, 3 and 4 of the punching and embossing machine 1.
- the punching station 2 includes a device consisting of a lower table 9 and an upper table 10.
- the lower table 9 is fixedly mounted in the machine frame and provided with a counter plate to the punching knife.
- the upper table 10 is mounted vertically movable and driven by a drive for the device.
- the upper table 10 includes a frame 15 for receiving a support plate 16 which is provided with punching and Rillenmessern.
- the gripper bar 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent breaking station 3, which may be equipped with breakout tools.
- the unwanted pieces of waste are pushed out of the sheet downwards with the aid of the stripping tools, whereby these pieces of waste 11 fall into a container-like carriage 12 inserted below the station.
- the depositing station 4 may also include a pallet 13 on which the individual sheets are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets can be moved away with the stacked sheets 14 from the field of punching and embossing machine 1.
- the chains 7 carry a plurality of gripper bars 8, for example, there are eight, so that multiple sheets 6 can be processed simultaneously in the various stations 2, 3 and 4.
- FIG. 2 shows the plan view of a frame 15 for receiving a support plate 16 as part of a device which can be moved out of the punching station 2.
- clamping elements 17, 18 are integrated to fix the support plate 16.
- the exemplary embodiment shows a frame 15 which is transverse to the running direction 19 on both sides with two and in the direction 19 on one side with four clamping elements 17, 18 is equipped.
- the clamping elements 17, 18 via pressure lines 20 with hydraulic cylinders 21, 22 are connected.
- the clamping elements 18 are acted upon via the hydraulic cylinder 21 and the clamping elements 17 via the hydraulic cylinder 22 with pressure.
- the frame On a longitudinal side 25 of the frame 15, the frame is provided with a cylindrical pin 26, through which the support plate 16 is positioned during insertion.
- the alignment of the support plate 16 is then carried out first by the fixing by means of the hydraulic system 23 and then by the fixing by means of the hydraulic system 24, as described in more detail below.
- the support plate 16 is inserted by the operator in the frame 15 and roughly positioned over a cylinder pin 26 attached to the longitudinal side 25 of the frame. On this longitudinal side 25 no hydraulic clamping elements 17, 18 are integrated into the frame 15.
- the clamping elements 18 are now pressurized by the operator. This is done by the operator manually activates the clamping screw 27 on the hydraulic cylinder 21, resulting in a successive pressure build-up in the hydraulic system 23 results, so that the clamping elements 18, the support plate 16 against the cylindrical pin 26 and the longitudinal side 25 fix.
- the hydraulic system 24 is pressurized by turning the clamping screw 28 on the hydraulic cylinder 22. Due to the successive pressure build-up in the clamping elements 17, the pistons of the clamping elements 17 all first contact the support plate 16.
- the support plate 16 With increasing pressure in the clamping elements 17, the support plate 16 is then also fixed transversely to the direction of rotation 19.

- the hydraulic systems 23, 24 consist primarily of the hydraulic cylinders 21, 22 the pressure lines 20 and the clamping elements 17, 18.
- the hydraulic cylinder 21 consists essentially of a cylinder 29, a clamping screw 27, a guided Piston 30 and a spring assembly 31. To the hydraulic cylinder 29, the pressure line 20 is connected.
- the piston 30 In order to pressurize the hydraulic fluid, which consists in particular of hydraulic oil, the piston 30 is pushed by means of the clamping screw 27 into the cylinder space 32. After reaching a defined pressure, the piston 30 presses the spring assembly 31 in the direction of the clamping screw 27 and thus builds up a bias on the hydraulic fluid. Should it now, for example in the case of leakage, come to a pressure drop so the spring assembly 31 counteracts the pressure drop. The hydraulic system 23 is thus able to compensate for a pressure drop. Since there are only small amounts of hydraulic fluid in the hydraulic system 23, a leakage in which very small amounts of hydraulic fluid escape would cause a large pressure drop.
- FIG. 4 shows the basic structure of a tensioning element, 17.
- the pressure line 20 is screwed directly into the clamping element 17 and supplies a piston-cylinder unit 33, 34 with hydraulic fluid, wherein the piston 33 is provided with a pressure member 35 which acts directly on the support plate 16. If the clamping element 17 is acted upon by a pressure, then the piston 33 moves in the direction of the support plate 16 and fixes it in the frame 15, a usual operating pressure is several hundred bar here.
- the clamping elements 17 generate a force of well over 500 N per clamping element. In the pressureless state, the piston 33 returns to its original position.
- the provision can also be made by means of a piston return spring, not shown.
- clamping elements 17, 18 it is also conceivable as clamping elements 17, 18 to use mutually displaceable guided wedges.
- the piston-cylinder unit acts on a wedge and pushes the other wedge toward the support plate 16, so that the support plate 16 is positioned and fixed via the wedges or a piston arranged on the wedge.
- the return of the wedges then takes place either via the relaxation of the piston-cylinder unit or via a return spring.

Description
Die Erfindung, in den Ansprüchen 1 und 6 definiert, betrifft eine Bogenstanz- und prägemaschine mit einer Vorrichtung zum Stanzen von Nutzen aus Bögen, mit einem Rahmen zur Aufnahme einer mit Stanz- und Rillenmessern bestückten Tragplatte, die in dem Rahmen mittels hydraulischer Spannelemente gehalten istThe invention, defined in claims 1 and 6, relates to a sheet punching and embossing machine with a sheet punching utility, comprising a frame for receiving a support plate provided with punching and grooved blades, which is held in the frame by means of hydraulic tensioning elements
Aus der DE 195 16 073 A1 ist eine Vorrichtung für eine Bogenstanz- und prägemaschine bekannt. In dem beschriebenen Aufnahmerahmen der Vorrichtung wird die Tragplatte mittels Justier- und Halteschrauben eingespannt und grob ausgerichtet. Die Felneinstellung erfolgt dann über die Verstellung von Anschlägen im Aufnahmerahmen der Tragplatte. Zum Einspannen. Ausrichten und anschließenden Feineinstellen muß ein Bediener die Justier- und Halteschrauben manuell anziehen und den-Aufnahmerahmen ebenfalls manuell verstellen bis die Tragplatte exakt ausgerichtet in der Vorrichtung eingespannt ist.From DE 195 16 073 A1 a device for a sheet punching and embossing machine is known. In the described mounting frame of the device, the support plate is clamped by means of adjusting and retaining screws and roughly aligned. The Felneinstellung then takes place via the adjustment of stops in the mounting frame of the support plate. For clamping. Aligning and subsequent fine tuning an operator must manually tighten the adjustment and holding screws and also adjust the receiving frame manually until the support plate is clamped exactly aligned in the device.
Zur Reduzierung der Rüstzeiten ist es bekannt, hydraulische Spannelemente in den Aufnahmerahmen der Tragplatte zu integrieren, wie aus dem Geschäftsbericht des Jahres 2001 der Firma Jagenberg in Neuss hervorgeht. Hierin ist ein Aufnahmerahmen, der üblicherweise auch als Schließrahmen bezeichnet wird, beschrieben, bel dem die Stanzform im Gegensatz zur herkömmlichen Klemmung über Schrauben durch Hydraulikzylinder im Schiießrahmen fixiert wird.To reduce set-up times, it is known to integrate hydraulic clamping elements in the mounting frame of the support plate, as shown in the annual report of the year 2001 of the company Jagenberg in Neuss. Herein is a receiving frame, which is also commonly referred to as a closing frame, described, the bel the punching is fixed in contrast to the conventional clamping screws through hydraulic cylinders in the Schiießrahmen.
Weiterhin ist aus der US 6,012,491 ein Federkolbenspeicher bekannt, bei dem anstelle der Gasfüllung eine Schraubenfeder angeordnet ist, die auf einem Kolben lastet.Furthermore, from US 6,012,491 a spring piston accumulator is known in which instead of the gas filling a coil spring is arranged, which rests on a piston.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Stanzen von Nutzen aus Bögen für eine Bogenstanz- und Prägestation einer Bogenstanz- und -prägemaschine zu schaffen, die mit minimalen konstruktiven Mitteln eine Reduzierung der Rüstzeiten bei höchster Wiederholgenauigkeit ermöglicht und die gleichzeitig in der Lage ist Druckschwankungen im Hydrauliksystem zu kompensieren.The invention has for its object to provide a device for punching benefits from sheets for a sheet punching and embossing a Bogenstanz- and To create embossing machine that allows minimal design means a reduction of set-up times with the highest repeatability and at the same time is able to compensate for pressure fluctuations in the hydraulic system.
Diese Aufgabe wird entsprechend dem Patentanspruch 1 dadurch gelöst, dass der Druck im Hydrauliksystem über einen Kolben aufgebaut wird, der uber eine mechanische Feder auf eine vestellbare Spannschraube abgestützt ist. Durch das erfindungsgemäße hydraulische Spannen der Tragplatte entfällt ein mechanisches Spannen über Justier- und Halteschrauben, so dass die Tragplatte zur Positionierung und Fixierung im Rahmen lediglich vom Bediener eingelegt werden muß. Während des Einlegens der Tragplatte in den Rahmen erfolgt die Positionierung über einen am Rahmen befestigten Zylinderstift danach wird die Tragplatte mittels eines sukzessiven Druckaufbaus im Hydrauliksystem fixiert. Da durch den Bediener lediglich der Druck auf das Hydrauliksystem aufgebracht werden muß, entfällt das manuelle Ausrichten im Rahmen vollständig, so dass die Rüstzeit wesentlich reduziert wird.
Durch die Integration einer Feder oder eines Federpakets, zum Beispiel in Form von hintereinander angeordneten Tellerfedern, in den Zylinder des Hydrauliksystems, wobei die Feder mit dem Kolben in Verbindung steht, ist somit nun die Möglichkeit geschaffen einem Druckabfall, zum Beispiel im Falle einer Leckage, entgegen zu wirken. Dabei wird während des Druckaufbaus im Hydrauliksystem auf die Feder eine Vorspannung aufgebracht, so dass die Feder in der Lage ist einen Druckabfall zu kompensieren.This object is achieved according to the patent claim 1, characterized in that the pressure in the hydraulic system is constructed by a piston which is supported by a mechanical spring on a vestellbare clamping screw. Due to the inventive hydraulic clamping of the support plate eliminates a mechanical clamping on adjusting and retaining screws, so that the support plate for positioning and fixation in the frame only needs to be inserted by the operator. During insertion of the support plate in the frame positioning is done via a cylinder pin attached to the frame after the support plate is fixed by means of a successive pressure build-up in the hydraulic system. Since only the pressure on the hydraulic system must be applied by the operator, the manual alignment within the frame is completely eliminated, so that the set-up time is substantially reduced.
By the integration of a spring or a spring assembly, for example in the form of successively arranged disc springs in the cylinder of the hydraulic system, wherein the spring is in communication with the piston, the possibility is now created a pressure drop, for example in the event of leakage counteract. In this case, during the pressure build-up in the hydraulic system, a bias is applied to the spring, so that the spring is able to compensate for a pressure drop.

In Figur 1 ist der prinzipielle Aufbau einer Bogenstanz- und -prägemaschine 1 zum Stanzen, Ausbrechen und Ablegen von Bögen aus Papier, Pappe und dergleichen dargestellt. Die Stanz- und Prägemaschine 1 besteht aus einer Stanzeinrichtung 2, einer Ausbrecheinrichtung 3 und einer Ablegeeinrichtung 4, die von einem gemeinsamen Maschinengehäuse 5 getragen und umschlossen werden.In Figure 1, the basic structure of a sheet punching and embossing machine 1 for punching, breaking and depositing sheets of paper, cardboard and the like is shown. The punching and embossing machine 1 consists of a
Die Bögen 6 werden von auf umlaufenden Ketten 7 befestigten Greiferstangen 8 an ihrer Vorderkante ergriffen und intermittierend durch die verschiedenen Stationen 2, 3 und 4 der Stanz- und Prägemaschine 1 hindurchgezogen.The sheets 6 are gripped by mounted on rotating
Die Stanzstation 2 beinhaltet eine Vorrichtung bestehend aus einem Untertisch 9 und einem Obertisch 10. Der Untertisch 9 ist fest im Maschinengestell gelagert und mit einer Gegenplatte zum Stanzmesser versehen. Der Obertisch 10 ist vertikal bewegbar gelagert und über einen Antrieb für die Vorrichtung antreibbar. Dabei enthält der Obertisch 10 einen Rahmen 15 zur Aufnahme einer Tragplatte 16, die mit Stanz- und Rillenmessern versehen ist.The
Die Greiferstange 8 transportiert den Bogen 6 von der Stanz- und Prägestation 2 in die nachfolgende Ausbrechstation 3, die mit Ausbrechwerkzeugen ausgestattet sein kann. In der Ausbrechstation 3 werden mit Hilfe der Ausbrechwerkzeuge die nicht benötigten Abfallstücke aus dem Bogen nach unten herausgestoßen, wodurch diese Abfallstücke 11 in einen unter der Station eingeschobenen behälterartigen Wagen 12 fallen.The
Von der Ausbrechstation 3 gelangt der Bogen 6 in die Ablegestation 4, wo der Bogen entweder nur einfach abgelegt wird, oder aber günstiger gleichzeitig eine Trennung der einzelnen Nutzen erfolgt. Die Ablegestation 4 kann auch eine Palette 13 enthalten, auf der die einzelnen Bögen in Form eines Stapels 14 aufgestapelt werden, so daß nach Erreichen einer bestimmten Stapelhöhe die Paletten mit den aufgestapelten Bögen 14 aus dem Bereich der Stanz- und Prägemaschine 1 weggefahren werden können.From the breaking station 3, the sheet 6 passes into the depositing
Wie zu erkennen ist, tragen die Ketten 7 mehrere Greiferstangen 8, beispielsweise sind es hier acht, so daß mehrere Bögen 6 gleichzeitig in den verschiedenen Stationen 2, 3 und 4 bearbeitet werden können.As can be seen, the
Die Figur 2 zeigt die Draufsicht auf einen Rahmen 15 zur Aufnahme einer Tragplatte 16 als Teil einer aus der Stanzstation 2 herausfahrbaren Vorrichtung. In den Rahmen 15 sind umlaufend Spannelemente 17, 18 zur Fixierung der Tragplatte 16 integriert. Das Ausführungsbeispiel zeigt einen Rahmen 15 der quer zur Laufrichtung 19 beidseitig mit zwei und in Laufrichtung 19 einseitig mit vier Spannelementen 17, 18 ausgestattet ist. Zur Druckversorgung sind die Spannelemente 17, 18 über Druckleitungen 20 mit Hydraulikzylindern 21, 22 verbunden. Dabei werden die Spannelemente 18 über den Hydraulikzylinder 21 und die Spannelemente 17 über den Hydraulikzylinder 22 mit Druck beaufschlagt. Es sind somit zwei unabhängig voneinander arbeitende Hydrauliksysteme 23, 24 in den Rahmen 15 integriert.FIG. 2 shows the plan view of a
An einer Längsseite 25 des Rahmens 15 ist der Rahmen mit einem Zylinderstift 26 versehen, durch den die Tragplatte 16 während des Einlegens positioniert wird. Das Ausrichten der Tragplatte 16 erfolgt dann zuerst durch das Fixieren mittels des Hydrauliksystems 23 und anschließend durch das Fixieren mittels des Hydrauliksystems 24, wie im folgenden näher beschrieben.On a
Die Tragplatte 16 wird vom Bediener in den Rahmen 15 eingelegt und über einen an der Längsseite 25 des Rahmens befestigten Zylinderstift 26 grob positioniert. An dieser Längsseite 25 sind keine hydraulischen Spannelemente 17, 18 in den Rahmen 15 integriert. Zuerst werden nun die Spannelemente 18 vom Bediener mit Druck beaufschlagt. Dies geschieht, indem der Bediener die Spannschraube 27 am Hydraulikzylinder 21 manuell betätigt, woraus ein sukzessiver Druckaufbau im Hydrauliksystem 23 resultiert, so dass die Spannelemente 18 die Tragplatte 16 gegen den Zylinderstift 26 und die Längsseite 25 fixieren. Anschließend wird durch ein Drehen der Spannschraube 28 am Hydraulikzylinder 22 das Hydrauliksystem 24 mit Druck beaufschlagt. Durch den sukzessiven Druckaufbau in den Spannelementen 17 legen sich die Kolben der Spannelemente 17 zuerst alle an die Tragplatte 16 an. Mit steigendem Druck in den Spannelementen 17 wird die Tragplatte 16 dann auch quer zur Laufrichtung 19 fixiert. Zum Ausrichten der Tragplatte 16 muß der Bediener somit lediglich die beiden Spannschrauben 27, 28 der Hydrauliksysteme 23, 24 betätigen, so dass die Tragplatte 16 im Rahmen 15 mit minimalen Rüstzeiten eingespannt und ausgerichtet ist.The
Die Hydrauliksysteme 23, 24 bestehen vornehmlich aus den Hydraulikzylindern 21, 22 den Druckleitungen 20 und den Spannelementen 17, 18. In der Figur 3 ist ein Schnitt durch einen Hydraulikzylinder 21 dargestellt. Der Hydraulikzylinder 21 besteht im wesentlichen aus einem Zylinder 29, einer Spannschraube 27, einem geführten Kolben 30 und einem Federpaket 31. An den Hydraulikzylinder 29 ist die Druckleitung 20 angeschlossen.The
Um die Hydraulikflüssigkeit, die insbesondere aus Hydrauliköl besteht, unter Druck zu setzen wird der Kolben 30 mittels der Spannschraube 27 in den Zylinderraum 32 hineingeschoben. Nach dem Erreichen eines definierten Drucks drückt der Kolben 30 das Federpaket 31 in Richtung der Spannschraube 27 zusammen und baut so eine Vorspannung auf die Hydraulikflüssigkeit auf. Sollte es nun, zum Beispiel im Falle einer Leckage, zu einem Druckabfall kommen so wirkt das Federpaket 31 dem Druckabfall entgegen. Das Hydrauliksystem 23 ist somit in der Lage einen Druckabfall zu kompensieren. Da im Hydrauliksystem 23 nur kleine Mengen an Hydraulikflüssigkeit vorhanden sind, würde eine Leckage, bei der sehr geringe Mengen an Hydraulikflüssigkeit austreten, einen großen Druckabfall hervorrufen.In order to pressurize the hydraulic fluid, which consists in particular of hydraulic oil, the
Figur 4 zeigt den prinzipiellen Aufbau eines Spannelements,17. Die Druckleitung 20 ist unmittelbar in das Spannelement 17 eingeschraubt und versorgt eine Kolben-Zylindereinheit 33, 34 mit Hydraulikflüssigkeit, wobei der Kolben 33 mit einem Druckteil 35 versehen ist, das direkt auf die Tragplatte 16 wirkt. Wird das Spannelement 17 mit einem Druckbeaufschlagt, so verfährt der Kolben 33 in Richtung der Tragplatte 16 und fixiert diese im Rahmen 15, ein üblicher Betriebsdruck beträgt hier mehrere hundert bar. Die Spannelemente 17 erzeugen dabei ein Kraft von deutlich über 500 N je Spannelement. Im drucklosen Zustand fährt der Kolben 33 in seine Ausgangsstellung zurück. Die Rückstellung kann auch mittels einer nicht dargestellten Kolbenrückstellfeder erfolgen.FIG. 4 shows the basic structure of a tensioning element, 17. The
Im Sinne der Erfindung ist es ebenfalls vorstellbar als Spannelemente 17, 18 gegeneinander verschiebbare geführte Keile einzusetzen. In diesem Fall wirkt die Kolben-Zylindereinheit auf einen Keil und schiebt den anderen Keil in Richtung der Tragplatte 16, so dass die Tragplatte 16 über die Keile oder einen auf dem Keil angeordneten Kolben positioniert und fixiert wird. Die Rückstellung der Keile erfolgt dann entweder über das Entspannen der Kolben-Zylindereinheit oder über eine Rückstellfeder.For the purposes of the invention, it is also conceivable as clamping
