Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Bei einer nach dem Prospekt "Preston" PE 752-7/85, Preston Engravers, INC., Windsor, vorbekannten Vorrichtung dieser Art wird in einen Axialkanal des Stanzzylinders durch ein axial verschiebbares Rohr, in dessen Wandung sich Löcher befinden, Druckluft eingeführt. Beidseitig dieser Löcher ist das Rohr gegenüber dem Kanal abzudichten. Diese Vorrichtung ist nicht nur konstruktiv kompliziert, sondern gestattet auch nicht, starke Druckluftimpulse den Austrittsöffnungen innerhalb der geschlossenen Stanzkanten zuzuführen.In a device of this type previously known according to the "Preston" PE 752-7 / 85 prospect, Preston Engravers, INC., Windsor, compressed air is introduced into an axial channel of the punch cylinder through an axially displaceable tube, in the wall of which there are holes. The pipe must be sealed on both sides of these holes in relation to the sewer. This device is not only structurally complicated, but also does not allow strong compressed air pulses to be fed to the outlet openings within the closed punched edges.
Aufgabe der Erfindung ist es, eine Vorrichtung nach dem Oberbegriff des Anspruchs 1 anzugeben,die einfach konstruiert ist und die es gestattet, den Austrittsöffnungen innerhalb der Stanzkanten starke Druckluftstöße zuzuführen.The object of the invention is to provide a device according to the preamble of claim 1, which is of simple construction and which allows strong compressed air blasts to be supplied to the outlet openings within the punched edges.
Die Lösung dieser Aufgabe ist in Anspruch 1 angegeben.The solution to this problem is specified in claim 1.
Der Weg zwischen der Öffnung in der Seitenfläche der Gabel oder des Ringteils und den Austrittsöffnungen im Stanzzylinder kann kurz gehalten werden. Die Gabel oder das Ringteil wirkt gegenüber den Eintrittsöffnungen im Stanzzylinder als Ventilschieber. Dies hat starke Druckluftimpulse zur Folge.The path between the opening in the side surface of the fork or the ring part and the outlet openings in the punching cylinder can be kept short. The fork or the ring part acts as a valve slide in relation to the inlet openings in the punching cylinder. This results in strong pulses of compressed air.

Um zu erreichen, daß ausgestanzte Materialbereiche nicht an dem Eintrittsspalt des Kastens vorbeifliegen, ist bevorzugt eine Ausbildung nach Anspruch 8 vorgesehen.In order to ensure that punched-out material areas do not fly past the entry gap of the box, an embodiment according to
Besonders hohe Impulsverluste der ausgestanzten Materialbereiche erhält man durch die Ausbildung nach Anspruch 9, die den Innenraum des Kastens für die ausgestanzten Materialbereiche labyrinthartig macht.Particularly high momentum losses of the punched-out material areas are obtained by the design according to claim 9, which makes the interior of the box for the punched-out material areas labyrinthine.
Die Stanzzylinder können axial kurz oder lang sein. Sind sie kurz, so ähnelt ihre Form mehr einer Scheibe als einem Zylinder im üblichen Sprachgebrauch.The punch cylinders can be short or long axially. If they are short, their shape is more like a disk than a cylinder in common usage.
Die Vorrichtung eignet sich zum Abfördern von beliebigem blattförmigem Material aus gestanzten Materialbereichen, wie zum Abfördern von Stanzresten aus durch Stanzen gelochten Bahnrändern, aber auch zum Abfördern von aus blattförmigem Material ausgestanzten Etiketten. Die Stanzzylinder können die Form von Stanzringen haben, als Vollkörper ausgebildet sein, aus Segmenten zusammengesetzt sein oder auch aus einem Trägerzylinder mit aufgesteckter Stanzhülse bestehen.The device is suitable for removing any sheet material from punched material areas, such as for removing stamping remnants from web edges perforated by stamping, but also for removing labels punched out of sheet material. The punching cylinders can have the shape of punching rings, be designed as a solid body, be composed of segments or also consist of a carrier cylinder with a punching sleeve attached.
Die Erfindung wird im folgenden an Ausführungsbeispielen unter Hinweis auf die beigefügten Zeichnungen beschrieben.The invention is described below using exemplary embodiments with reference to the accompanying drawings.
Fig. 1 zeigt perspektivisch zwei scheibenförmige Stanzzylinder mit mit ihnen zusammenwirkenden Gabeln.Fig. 1 shows in perspective two disc-shaped punch cylinders with forks cooperating with them.
Fig. 2 zeigt, teils im Schnitt, eine Ansicht eines Stanzzylinders nach Fig. 1 von dessen Schmalseite aus mit zugeordneter Gabel.Fig. 2 shows, partly in section, a view of a punch cylinder according to Fig. 1 from its narrow side with an associated fork.
Fig. 3 zeigt eine Seitenansicht eines Stanzzylinders nach Fig. 1 mit zugeordneter Gabel, teilweise im Schnitt.Fig. 3 shows a side view of a punch cylinder according to Fig. 1 with an associated fork, partially in section.
Fig. 4 zeigt einen Stanzzylinder mit aufgesetzten Stanzsegmenten und zugeordneter Gabel.Fig. 4 shows a punch cylinder with attached punch segments and an associated fork.

Fig. 6 zeigt eine geschlossene Stanzkante, in der eine Druckluft-Austrittsöffnung liegt.Fig. 6 shows a closed punching edge, in which a compressed air outlet opening lies.
Fig. 7 zeigt eine geschlossene Stanzkante, in der zwei Druckluft-Austrittsöffnungen liegen.Fig. 7 shows a closed punched edge in which two compressed air outlet openings are located.
Fig. 8 zeigt ein Ende eines Stanzzylinders mit einem mit ihm zusammenwirkenden Ring und einem Antriebszahnrad in Explosionsdarstellung.Fig. 8 shows an end of a punch cylinder with a ring cooperating with it and a drive gear in an exploded view.
Fig. 9 zeigt einen Schnitt längs der Linie IX - IX in Fig. 8 nach Zusammensetzung der in Fig. 8 dargestellten Teile.FIG. 9 shows a section along the line IX-IX in FIG. 8 according to the composition of the parts shown in FIG. 8.
Fig. 10 zeigt einen Kasten zur Aufnahme der ausgestanzten Materialbereiche in seinem Zusammenwirken mit einem Stanzzylinder und einem Widerlagerzylinder.10 shows a box for receiving the punched-out material areas in its interaction with a punching cylinder and an abutment cylinder.
Die Figuren 1 bis 3 zeigen eine ortsfest gelagerte, anzutreibende Welle 2, auf der axial verschiebbar und festlegbar zwei scheibenförmige Stanzzylinder 4, 6 drehfest sitzen. Die drehfeste Verbindung wird dadurch bewirkt, daß ein Keil auf der Welle in jeweils eine Nut 8 der Stanzzylinder 4, 6 eingreift.Figures 1 to 3 show a stationary, driven
Auf der Umfangsfläche der Stanzzylinder 4, 6 befinden sich kreisförmige geschlossene Stanzkanten 10, in denen jeweils eine Austrittsöffnung 12 eines Kanals 14 mündet, der eine in einer Seitenfläche 16 des Stanzzylinders 4, 6 mündende Eintrittsöffnung 18 aufweist. Der Seitenfläche 16 steht ein Flansch 20 an einem zylindrischen Ansatz 22 des Stanzzylinders 4, 6 gegenüber, der einen kleineren Außendurchmesser hat als der Stanzzylinder 4, 6. Der dadurch entstehende Ringraum 24 ist Armen 26, 28 einer Gabel 30 angepaßt, in der sich ein Druckluftzuführungskanal 32 befindet. Dieser Druckluftzuführungskanal 32 endet in einer seitlichen Öffnung 34 des Arms 28 der Gabel 30 und weist am Schaftende 36 der Gabel 30 einen Anschlußstutzen 38 auf, an den ein Druckluftzuführungsschlauch 40 anzuschließen ist. Die Gabel 30 ist mit einem parallel zur Welle 2 verlaufenden Führungsloch 42 versehen, das von einer Welle 44 durchsetzt ist. Die Welle 44 ihrerseits ist relativ zur Welle 2 radial verschiebbar gelagert. Die Gabel 30 kann somit axial und radial zu dem ihr jeweils zugeordneten Stanzzylinder 4 bzw. 6 verschoben werden. Die Gabel 30 ist im Betrieb stationär und der Stanzzylinder 4 bzw. 6 läuft um. Die aus der Öffnung 34 der Gabel 30 austretende Druckluft gelangt somit nacheinander in die Eintrittsöffnungen 18 der kurzen Kanäle 14 und wird, wenn sie beim Übergang von einem Kanal 14 zu einem folgenden Kanal 14 nicht in einer der Eintrittsöffnungen 18 eingeführt werden kann, gestaut. Daraus ergeben sich sehr hohe Druckluftimpulse.On the peripheral surface of the

Bei der Ausführungsform nach Fig. 4 ist ein langgestreckter Trägerzylinder 60 von Stanzsegmenten 62 vorgesehen, der axiale Zapfen 64, 66 zur Lagerung aufweist. Am einen Ende des Trägerzylinders 60 befindet sich ein Antriebszahnrad 68, das in axialem Abstand von einer Stirnfläche des Trägerzylinders 60 verläuft und somit Platz für eine Gabel 70 läßt, die grundsätzlich ebenso ausgebildet ist wie die Gabel 30 nach den Fig. 1 bis 3. Für die entsprechenden Elemente sind daher die gleichen Bezugsziffern verwendet. In dem Trägerzylinder verlaufen Axialbohrungen 72, die den Bohrungen 46, und Radialbohrungen 74, die den Radialbohrungen 48 entsprechen. Diese Radialbohrungen 74 koinzidieren mit Bohrungen 76 in den Stanzsegmenten 62. In diesem Fall umschließt jede geschlossene Stanzkante 78 der Stanzsegmente 62 vier Austrittsöffnungen 79.In the embodiment according to FIG. 4, an
Fig. 5 zeigt einen Stanzzylinder 80, an dem nur eine von mehreren geschlossenen Stanzkanten 82 angedeutet ist. Durch den Stanzzylinder 80 erstrecken sich Axialbohrungen 84, die den Axialbohrungen 46 entsprechen, und Radialbohrungen 86, die den Radialbohrungen 48 entsprechen. In Abstand von der Stirnfläche 88 des Stanzzylinders 80 ist über einen zylindrischen Ansatz 90 verringerten Durchmessers ein Zahnrad 92 angesetzt, auf dessen Außenseite sich ein Lagerzapfen 94 befindet. An der anderen Stirnseite 96 des Stanzzylinders 80 ist ebenfalls ein Lagerzapfen 98 angesetzt. Der Raum 100 zwischen der Stirnfläche 88 und dem Zahnrad 92 dient zur Aufnahme der nicht dargestellten Gabel.FIG. 5 shows a

Die Figuren 8 und 9 zeigen einen Stanzzylinder 130 mit vorspringenden geschlossenen Stanzkanten 132, innerhalb denen Austrittsöffnungen 134 für Druckluft münden. Die Druckluft wird den Austrittsöffnungen 134 über Kanäle 136 zugeführt, die innerhalb des Stanzzylinders 130 ausgebildet sind und Eintrittsöffnungen 138 an einer seitlichen Ringfläche 140 des Stanzzylinders 130 aufweisen. Die Ringfläche 140 umschließt einen Zylinderansatz 142 an dem Stanzzylinder 130, dessen Umfangsfläche 144 Lagerfläche für ein Ringteil 146 ist. In der der Ringfläche 140 zugewandten Seitenfläche 148 mündet eine in Umfangsrichtung des Stanzzylinders 130 langgestreckte Öffnung 150, aus der über einen im Ringteil 146 befindlichen Kanal 152 Druckluft den Eintrittsöffnungen 138 der Reihe nach zuzuführen ist. An dem Ringteil 146 ist einstückig ein der Montage dienendes Gabelteil 154 angesetzt. Der Kanal 152 endet eintrittsseitig in einem Innengewindeabschnitt 156, der einen Außengewindeansatz 158 an einem Druckluftzuführungsteil 160 aufnehmen kann. Auf dem zylindrischen Ansatz 152 befindet sich ein zweiter zylindrischer Ansatz 162 verringerten Durchmessers, auf den ein Zahnrad 164 aufgesetzt werden kann. Das Zahnrad 164 ist mittels Schrauben 166, die Löcher 168 im Zahnrad 164 durchsetzen, in Gewindelöchern 170 der Stirnseite des zylindrischen Ansatzes 142 festzuschrauben.FIGS. 8 and 9 show a
Fig. 10 zeigt einen Stanzzylinder 180, der mit einem unter ihm angeordneten drehbar gelagerten Widerlagerzylinder 182 zusammenwirkt. Auszustanzendes blattförmiges Material wird durch einen Spalt zwischen dem Stanzzylinder 180 und dem Widerlagerzylinder 182 geführt und anschließend schräg nach oben über eine drehbar gelagerte Stützwalze 186 abgeführt. Zur Aufnahme und Weiterführung der aus dem blattförmigen Material 184 ausgestanzten Materialbereiche ist ein Kasten 188 mit einem auf die jeweils unter Druckluft stehenden Austrittsöffnungen 190 des Stanzzylinders 180 gerichteten Eintrittsschlitz 192 vorgesehen. Der Kasten 188 ist innen als eine Art Labyrinth ausgebildet, an dessen Innenflächen die ausgestanzten Materialbereiche, wie durch ausgezogene Pfeile angedeutet, mehrfach reflektiert werden. Druckluft zieht durch den Kasten teils wirbelförmig, wie durch gestrichelte Pfeile angedeutet. Über einem Bodenbereich 194 des Kastens 188 mündet ein Abzugsstutzen 196 für die ausgestanzten Materialbereiche,der an eine nicht dargestellte Ansaugeinrichtung angeschlossen ist.10 shows a
Der Eintrittsschlitz 192 ist unten durch eine etwa tangential schräg nach oben zu dem Widerlagerzylinder 182 gerichtete Wand 198 begrenzt, an der eine die Umfangsfläche 200 des Widerlagerzylinders 182 abstreifende Rakel 202 angesetzt ist. Oben ist der Eintrittsschlitz 192 des Kastens durch eine von dem Stanzzylinder 180 fort weisende Wand 204 begrenzt, die im Querschnitt mit der an sie angrenzenden Wand 206 des Kastens 188 annähernd ein L bildet.The
