Definitions
- the invention relates to a folder with a smooth cutting device consisting of two knife cylinders equipped with scissor cut knives, one of which is provided with puncture needles adjacent to its scissor cut knives for holding the sections and dips with a part of its circumference into a suction channel.
- a folder of this type is known for example from DE-A-30 30 706.
- Such arrangements can lead to malfunctions in that the sections needled onto the puncture needles are not pulled off the puncture needles reliably enough in the region of the suction channel. The consequence of this is that several sections come to lie on top of each other and the lower ones Sections are pushed further and further onto the pin needles.
- the measures according to the invention ensure that the cylinder containing the puncture needles and blowing nozzles is not unduly weakened.
- the measures according to the invention are therefore advantageous, in particular in the case of knife cylinders with a small diameter, and ensure that in the case of folding apparatuses for the production of small product formats, unnecessarily large cylinder diameters are not required.
- Another advantage of the measures according to the invention can be seen in the fact that air is fed into the suction duct through the blowing nozzles, so that the amount of air sucked in from outside and accordingly the air flow resulting outside the suction duct are reduced, so that even with a comparatively strong suction draft inside of the suction channel there is no disturbance of the folding products passing through the folding device and a high level of noise.
- the cylinder containing the blow nozzles can be provided with at least one radially opening connection bore connected to the blow nozzles and can be enclosed in the region of the connection bore by a stationary block connected by one to the compressed air line Supply channel is penetrated, the inner mouth of which is run over by the mouth of the connecting bore.
- the block can expediently be pivotable and fixable with respect to the axis of the associated knife cylinder. This makes it possible to easily set the angular range within which compressed air is applied to the blowing nozzles.
- a further advantageous measure can consist in the mouth of the supply channel ending in a control chamber which extends over a circumferential angle which corresponds approximately to the circumferential angle over which the suction duct extends.
- a sleeve containing the control chamber can advantageously be inserted into the block. This measure enables particularly simple manufacture.
- the folding apparatus on which FIG. 1 is based contains a folding knife cylinder 1, the folding knife 2 of which with the Interacting jaws 3 of a jaw cylinder 4. This carries in the area between the jaws 3 scissors cutters 5 which cooperate with scissors cutters 7 arranged on an adjacent knife cylinder 6.
- the scissor cut knives 5 and 7 effect a smooth cut at the rear end of the products accommodated in the folding jaws 3.
- the products are delivered from the folding jaw cylinder 4 either to an adjacent belt guide or an adjacent paddle wheel.
- the stripe-shaped product sections resulting from the execution of the smooth cut are needled on the scissor cut knives 7 of the knife cylinder 6, that is to say set back in relation to them in the cylinder rotation direction, on the knife cylinder 6 stationary needle needles 8 and then suctioned off.
- a suction channel 9 is provided, into which the knife cylinder 6 is immersed with part of its circumference in such a way that the channel entrance is covered.
- the removal of the product sections from the puncture needles 8 is supported by measures on the cylinder side.
- the knife cylinder 6, as can best be seen from FIG. 2, is provided with the blowing needles 8 adjacent to the puncture needles 8. These are arranged in a row and in an alternating sequence with the puncture needles 8.
- the blow nozzles 10 are formed by radial bores with a small diameter of approximately 2 mm.
- the blowing nozzles 10 can be acted upon by compressed air as they pass through the circumferential area encompassed by the suction channel 9, as a result of which the product sections 11 needled on the pin needles 8, indicated by a dash-dotted line in FIG. 2, are lifted off the pin needles 8 and the suction channel 9 is fed with air.
- a compressed air line 12 is provided connected to a compressed air source, for example an internal compressed air network, which is connected via a rotating union to a bore system provided on the cylinder side, which leads from a radially opening connection bore 13 to the radial bores forming the blower nozzles 10.
- the radial bores forming the blowing nozzles start from an axial bore 14 which is continuous over the cylinder length and is closed in the region of the cylinder end faces and which is connected via a radial bore 15 which is likewise closed on the circumference to a central axial blind bore 16 which is closed on the end face and into which the radial connecting bore 13 opens.
- the knife cylinder 6 is provided with lateral journals 17 which are mounted in the associated frame walls 18. One of the journals 17 is provided with an extension extending beyond the associated frame wall 18 for receiving the connection bore 13 and the rotating union.
- the rotary feedthrough contains a block 20 which is provided with a bore 19 parallel to the cylinder and which is attached to the extension of the bearing pin 17 containing the connection bore 13.
- the block 20, which can be pivoted about the cylinder axis, can be connected to the adjacent frame wall 18 by means of a retaining screw 21 and can thus be secured against rotation.
- the block 20 is secured in the axial direction by clamping rings and spacer sleeves.
- the block 20 is provided with a radial bore forming a supply channel 22, to the circumferential end of which the compressed air line 12 connects and which passes through to the bore 19 parallel to the cylinder.
- the local inner mouth of the supply channel 22 is accordingly run over with each revolution of the knife cylinder 6 from the outer end of the connection bore 13, with the blowing nozzles 10 being pressurized with compressed air.
- a nipple 25 is provided for connecting the compressed air line 12 to the outer end of the radial bore 22 forming the supply channel.
- the retaining screw 21 is simply loosened and the block 20 is rotated accordingly. Accordingly, as can best be seen in FIG. 3, the latter is provided with an elongated hole 23 penetrated by the retaining screw 21 and concentric with the cylinder axis.
- a bushing 24 containing the bore 19 is inserted into the block 20 and has a circumferential recess 25 into which the radial bore forming the supply channel 22 runs.
- the recess 24 practically forms a control chamber for extending the compressed air supply to the blowing nozzles 10 over the diameter of the supply channel 22 corresponding angular range.
- the recess 24 accordingly extends over a circumferential angle which corresponds approximately to the circumferential angle within which the knife cylinder 6 dips into the intake duct 9.

Description
Die Erfindung betrifft einen Falzapparat mit einer Glattschnitteinrichtung bestehend aus zwei mit Scherenschnittmessern besetzten Messerzylindern, von denen einer mit seinen Scherenschnittmessern benachbarten Punkturnadeln zum Halten der Abschnitte versehen ist und mit einem Teil seines Umfangs in einen Absaugkanal eintaucht.The invention relates to a folder with a smooth cutting device consisting of two knife cylinders equipped with scissor cut knives, one of which is provided with puncture needles adjacent to its scissor cut knives for holding the sections and dips with a part of its circumference into a suction channel.
Ein Falzapparat dieser Art ist beispielsweise aus der DE-A-30 30 706 bekannt. Bei derartigen Anordnungen kann es dadurch zu Störungen kommen, daß die auf den Punkturnadeln aufgenadelten Abschnitte im Bereich des Absaugkanals nicht zuverlässig genug von den Punkturnadeln abgezogen werden. Die Folge davon ist, daß mehrere Abschnitte übereinander zu liegen kommen und die unteren Abschnitte immer weiter auf die Punkturnadeln aufgeschoben werden.A folder of this type is known for example from DE-A-30 30 706. Such arrangements can lead to malfunctions in that the sections needled onto the puncture needles are not pulled off the puncture needles reliably enough in the region of the suction channel. The consequence of this is that several sections come to lie on top of each other and the lower ones Sections are pushed further and further onto the pin needles.
Man könnte zwar versuchen, den im Absaugkanal wirksamen Saugzug zu erhöhen. Dies würde jedoch zu einer starken Luftbewegung in der Umgebung des Saugkanals und dementsprechend auch zu einer Beunruhigung der den Falzapparat durchlaufenden Falzprodukte führen. Außerdem wäre aufgrund der Luftströmung eine Lärmbelästigung zu erwarten, von dem erforderlichen Aufwand einmal ganz abgesehen.One could try to increase the effective suction in the suction channel. However, this would lead to a strong air movement in the vicinity of the suction channel and, accordingly, to a disturbance in the folding products passing through the folder. In addition, noise pollution would be expected due to the air flow, not to mention the effort required.
Es wäre auch denkbar, die auf den Punkturnadeln aufgenadelten Abschnitte durch auf dem die Punkturnadeln aufweisenden Messerzylinder vorgesehene, mechanische Ausheber zuverlässig außer Eingriff mit den Punkturnadeln zu bringen. Die genannten Ausheber würden jedoch vergleichsweise große Zylinderausschnitte erforderlich machen. Insbesondere bei Zylindern mit kleinerem Durchmesser wäre daher eine sehr große Schwächung des Zylinders und dementsprechend eine hohe Labilität zu befürchten.It would also be conceivable to reliably bring the sections needled onto the pin needles out of engagement with the pin needles by mechanical lifters provided on the knife cylinder having the pin needles. However, the lifters mentioned would require comparatively large cylinder cutouts. Particularly in the case of cylinders with a smaller diameter, a very large weakening of the cylinder and, accordingly, a high degree of instability would therefore be feared.
Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung eine Anordnung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß eine zuverlässige Entfernung der Abschnitte von den Punkturnadeln gewährleistet ist und daß dennoch die Zylinderstabilität nicht nennenswert beeinträchtigt wird.Proceeding from this, it is therefore the object of the present invention to improve an arrangement of the type mentioned at the outset with simple and inexpensive means in such a way that a reliable removal of the sections from the puncture needles is ensured and that the cylinder stability is nevertheless not appreciably impaired.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß den Punkturnadeln benachbarte Blasdüsen vorgesehen sind, die an eine Druckluftleitung angeschlossen sind, die im Takt der Zylinderdrehung so auf- und absteuerbar ist, daß die Blasdüsen beim Vorbeigang am Absaugkanal mit Druckluft versorgbar sind.This object is achieved in that adjacent puncture needles are provided, which are connected to a compressed air line which can be opened and closed in time with the rotation of the cylinder, so that the blowing nozzles can be supplied with compressed air as they pass the suction channel.
Mit diesen Maßnahmen werden die oben geschilderten Nachteile vollständig vermieden. Die erfindungsgemäßen Maßnahmen stellen sicher, daß eine unzulässige Schwächung des die Punkturnadeln und Blasdüsen enthaltenden Zylinders unterbleibt. Die erfindungsgemäßen Maßnahmen kommen daher insbesondere bei Messerzylindern mit kleinem Durchmesser vorteilhaft zum Tragen und stellen sicher, daß bei Falzapparaten zur Herstellung kleiner Produktformate nicht unnötig große Zylinderdurchmesser benötigt werden. Ein weiterer Vorteil der erfindungsgemäßen Maßnahmen ist darin zu sehen, daß durch die Blasdüsen Luft in den Absaugkanal eingespeist wird, so daß die von außen angesaugte Luftmenge und dementsprechend die außerhalb des Ansaugkanals sich ergebende Luftströmung reduziert werden, so daß auch bei einem vergleichsweise starken Saugzug innerhalb des Absaugkanals eine Beunruhigung der den Falzapparat durchlaufenden Falzprodukte sowie eine hohe Lärmentwicklung unterbleiben.With these measures, the disadvantages described above are completely avoided. The measures according to the invention ensure that the cylinder containing the puncture needles and blowing nozzles is not unduly weakened. The measures according to the invention are therefore advantageous, in particular in the case of knife cylinders with a small diameter, and ensure that in the case of folding apparatuses for the production of small product formats, unnecessarily large cylinder diameters are not required. Another advantage of the measures according to the invention can be seen in the fact that air is fed into the suction duct through the blowing nozzles, so that the amount of air sucked in from outside and accordingly the air flow resulting outside the suction duct are reduced, so that even with a comparatively strong suction draft inside of the suction channel there is no disturbance of the folding products passing through the folding device and a high level of noise.
In vorteilhafter Weiterbildung der übergeordneten Maßnahmen kann der die Blasdüsen enthaltende Zylinder mit wenigstens einer mit den Blasdüsen verbundenen, radial ausmündenden Anschlußbohrung versehen und im Bereich der Anschlußbohrung von einem stationären Block umfaßt sein, der von einem an die Druckluftleitung angeschlossenen Versorgungskanal durchsetzt ist, dessen innere Mündung von der Mündung der Anschlußbohrung überfahren wird. Diese Maßnahmen ergeben in vorteilhafter Weise eine Selbststeuerung der Druckluftbeaufschlagung.In an advantageous further development of the superordinate measures, the cylinder containing the blow nozzles can be provided with at least one radially opening connection bore connected to the blow nozzles and can be enclosed in the region of the connection bore by a stationary block connected by one to the compressed air line Supply channel is penetrated, the inner mouth of which is run over by the mouth of the connecting bore. These measures advantageously result in self-control of the compressed air supply.
Zweckmäßig kann der Block bezüglich der Achse des zugeordneten Messerzylinders schwenkbar und feststellbar sein. Hierdurch ist es möglich, den Winkelbereich, innerhalb dessen eine Druckluftbeaufschlagung der Blasdüsen erfolgt, auf einfache Weise einzustellen.The block can expediently be pivotable and fixable with respect to the axis of the associated knife cylinder. This makes it possible to easily set the angular range within which compressed air is applied to the blowing nozzles.
Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß der Versorgungskanal mündungsseitig in eine Steuerkammer ausläuft, die sich über einen Umfangswinkel erstreckt, der etwa dem Umfangswinkel entspricht, über den sich der Saugkanal erstreckt. Diese Maßnahmen ergeben eine besonders hohe Zuverlässigkeit.A further advantageous measure can consist in the mouth of the supply channel ending in a control chamber which extends over a circumferential angle which corresponds approximately to the circumferential angle over which the suction duct extends. These measures result in a particularly high level of reliability.
Mit Vorteil kann in den Block eine die Steuerkammer enthaltende Büchse eingesetzt sein. Diese Maßnahme ermöglicht eine besonders einfache Herstellbarkeit.A sleeve containing the control chamber can advantageously be inserted into the block. This measure enables particularly simple manufacture.
Weitere zweckmäßige Fortbildungen und vorteilhafte Weiterbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben.Further expedient further training and advantageous further training of the superordinate measures are specified in the remaining subclaims.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

Der der Figur 1 zugrundeliegende Falzapparat enthält einen Falzmesserzylinder 1, dessen Falzmesser 2 mit den Falzklappen 3 eines Falzklappenzylinders 4 zusammenwirken. Dieser trägt im Bereich zwischen den Falzklappen 3 angeordnete Scherenschnittmesser 5, die mit auf einem benachbarten Messerzylinder 6 angeordneten Scherenschnittmessern 7 zusammenwirken. Die Scherenschnittmesser 5 und 7 bewirken einen Glattschnitt am hinteren Ende der in den Falzklappen 3 aufgenommenen Produkte. Vom Falzklappenzylinder 4 werden die Produkte entweder an eine benachbarte Bandführung oder ein benachbartes Schaufelrad abgegeben.The folding apparatus on which FIG. 1 is based contains a
Die bei der Durchführung des Glattschnitts anfallenden, streifenförmigen Produktabschnitte werden auf den Scherenschnittmessern 7 des Messerzylinders 6 benachbarten, das heißt gegenüber diesen in Zylinderdrehrichtung zurückversetzten, auf dem Messerzylinder 6 stationär angeordneten Punkturnadeln 8 aufgenadelt und anschließend abgesaugt. Hierzu ist ein Absaugkanal 9 vorgesehen, in den der Messerzylinder 6 mit einem Teil seines Umfangs so eintaucht, daß der Kanaleingang abgedeckt wird. Um den innerhalb des Saugkanals 9 erforderlichen Saugzug in Grenzen zu halten, wird die Entfernung der Produktabschnitte von den Punkturnadeln 8 durch zylinderseitige Maßnahmen unterstützt.The stripe-shaped product sections resulting from the execution of the smooth cut are needled on the
Hierzu ist der Messerzylinder 6, wie am besten aus Figur 2 erkennbar ist, mit den Punkturnadeln 8 benachbarten Blasdüsen 10 versehen. Diese sind in einer Reihe und in alternierender Reihenfolge mit den Punkturnadeln 8 angeordnet. Die Blasdüsen 10 werden durch Radialbohrungen mit einem kleinen Durchmesser von etwa 2 mm gebildet.For this purpose, the
Die Blasdüsen 10 sind beim Durchlaufen des vom Absaugkanal 9 umfaßten Umfangsbereichs mit Druckluft beaufschlagbar, wodurch die auf den Punkturnadeln 8 aufgenadelten, in Figur 2 durch eine strichpunktierte Linie angedeuteten Produktabschnitte 11 von den Punkturnadeln 8 abgehoben und der Absaugkanal 9 mit Luft gespeist werden.The blowing
Hierzu ist eine an eine Druckluftquelle, beispielsweise ein betriebsinternes Druckluftnetz, angeschlossene Druckluftleitung 12 vorgesehen, die über eine Drehdurchführung mit einem zylinderseitig vorgesehenen Bohrungssystem verbunden ist, das von einer radial ausmündenden Anschlußbohrung 13 bis zu den die Blasdüsen 10 bildenden Radialbohrungen führt. Die die Blasdüsen 10 bildenden Radialbohrungen gehen von einer über die Zylinderlänge durchgehenden, im Bereich der Zylinderstirnseiten verschlossenen Axialbohrung 14 ab, die über eine umfangsseitig ebenfalls verschlossene Radialbohrung 15 mit einer zentralen, stirnseitig verschlossenen Axialsackbohrung 16 verbunden ist, in welche die radiale Anschlußbohrung 13 mündet. Der Messerzylinder 6 ist mit seitlichen Lagerzapfen 17 versehen, die in zugeordneten Gestellwänden 18 gelagert sind. Einer der Lagerzapfen 17 ist mit einer über die zugeordnete Gestellwandung 18 hinausgehenden Verlängerung zur Aufnahme der Anschlußbohrung 13 und der Drehdurchführung versehen.For this purpose, a
Die Drehdurchführung enthält einen mit einer zylinderachsparallelen Bohrung 19 versehenen Block 20, der auf die die Anschlußbohrung 13 enthaltende Verlängerung des Lagerzapfens 17 aufgesteckt ist. Der bezüglich der Zylinderachse schwenkbare Block 20 ist mittels einer Halteschraube 21 mit der benachbarten Gestellwandung 18 verbindbar und so gegen Verdrehung sicherbar. In axialer Richtung ist der Block 20 durch Spannringe und Distanzbüchsen gesichert. Der Block 20 ist mit einer einen Versorgungskanal 22 bildenden Radialbohrung versehen, an deren umfangsseitiges Ende die Druckluftleitung 12 anschließt und die bis zur zylinderachsparallelen Bohrung 19 durchgeht. Die dortige, innere Mündung des Versorgungskanals 22 wird dementsprechend bei jeder Umdrehung des Messerzylinders 6 vom äußeren Ende der Anschlußbohrung 13 überfahren, wobei eine Druckluftbeaufschlagung der Blasdüsen 10 erfolgt. Zum Anschluß der Druckluftleitung 12 an das äußere Ende der dem Versorgungskanal bildenden Radialbohrung 22 ist ein Nippel 25 vorgesehen.The rotary feedthrough contains a
Um den Winkelbereich, in welchem eine Druckluftbeaufschlagung der Blasdüsen erfolgen soll, einzustellen, wird einfach die Halteschraube 21 gelöst und der Block 20 entsprechend verdreht. Dieser ist dementsprechend, wie am besten aus Figur 3 erkennbar ist, mit einem von der Halteschraube 21 durchgriffenen, zur Zylinderachse konzentrischen Langloch 23 versehen.In order to set the angular range in which compressed air is to be applied to the blowing nozzles, the
Im dargestellten Ausführungsbeispiel ist in den Block 20 eine die Bohrung 19 enthaltende Büchse 24 eingesetzt, die eine umfangsseitige Aussparung 25 aufweist, in welche die den Versorgungskanal 22 bildende Radialbohrung einläuft. Die Aussparung 24 bildet praktisch eine Steuerkammer zur Verlängerung der Druckluftbeaufschlagung der Blasdüsen 10 über den dem Durchmesser des Versorgungskanals 22 entsprechenden Winkelbereich hinaus. Die Aussparung 24 erstreckt sich dementsprechend über einen Umfangswinkel, der etwa dem Umfangswinkel entspricht, innerhalb dessen der Messerzylinder 6 in den Ansaugkanal 9 eintaucht.In the exemplary embodiment shown, a
