Definitions
- the invention relates to a device for connecting a beginning of a rotating reserve residual paper roll to a moving paper web of a residual paper roll according to the preamble of claim 1.
- a device according to the preamble of claim 1 is known from US-A-1 967 056.
- a device for gluing a new web to a running paper web is known in that the new paper roll has a prepared adhesive tip on the outside at its beginning of the paper web, which is connected to the running paper web of the paper roll coming to an end by pressing brush elements . Since stretching of the paper web, which can lead to tearing of the paper, is to be avoided during the pressing process for connecting the two paper webs, two movable rods or rollers are provided according to the above-mentioned DE-PS 8 78 945. While one roller presses the running paper web of the end of the paper roll to the beginning of the new paper roll, another roller is moved in the opposite direction.
- a disadvantage of this device is that the two rollers have a relatively large mass inertia, which cannot be overcome in a fraction of a second, in order to carry out the gluing device, since the paper throughput speed of today's high-performance web-fed rotary printing presses allows a very limited time for the gluing processes .
- a paper web gluing device for rotary printing presses in which the running web is brought into contact with the new roll by means of a guide roller and at the same time a pressure brush for pressing the running web against the prepared adhesive point of the new paper roll and a second Roller to compensate for the change in length of the running web occurred, the actuating means of the two rollers and the brush are coupled to one another in such a way that the guide roller, the pressure brush and the compensating roller are adjusted by means of a screw drive actuated by a briefly switchable motor, which engages on a lever attached to the brush shaft, to which an actuating rod is pivoted for pivoting the guide and compensating roller.
- a disadvantage of this device is that a large amount of drive and transmission elements is required to connect the two paper webs to one another.
- the drive elements have such a mass inertia that the gluing or connecting process of the paper webs takes place in periods that are unacceptable in today's high-performance web-fed rotary printing press at a paper running speed of 15 m / s and more.
- the invention has for its object to provide a generic device in which an increase in the paper tension can be largely avoided during the connection of two paper webs during the paper roll changing process.
- the paper webs are connected to one another without changing the paper tension as a result of a paper length compensation, which inevitably takes place without the need for high expenditure on gear technology. Stretching or tearing of the paper web, even at high machine speeds, can thus be excluded.
- Fig. 1 is in a machine frame 1, a roller carrier 2, which has an expiring, ie. H. end of paper roll 3 and a new paper roll 4 with a prepared adhesive tip.
- the roller carrier 2 also carries a paper guide roller 6 which is fixedly arranged on an arm and is rotatably mounted.
- a pivotable support frame designated overall by 7, has two side parts 8 running parallel to the machine frame 1; 9, of which only the side part 8 is visible.
- the side parts 8; 9 connected via an axis of rotation 12 for a double-armed lever 13 of an equalizing device, denoted overall by 15, shown here without a drive.
- the support frame 7 can be moved via its drive shaft 11 into a rest position B shown in dashed lines in a parallel guide fixed to the frame, which is designated overall by 14.
- guide levers 16; 17 on the side parts 8; 9 articulated which are fixed to the frame at their opposite ends.
- the support frame 7 can be pivoted through an angle ⁇ of approximately 120 ° from the preparation position into the rest position, so that the guide levers 16; 17 and the support frame 7 assume the dashed position B.
- the parts 17 and 19 mentioned are also not visible in FIG. 1.
- the double-armed lever 13 - twice present - is on the axis of rotation 12 with the side parts 8; 9 connected and carries a guide roller 21 on its end facing the roller carrier 2 and a guide roller on its end facing away from the roller carrier 2 22.
- the guide roller 22 serves as an adhesive roller and the guide roller 21 can be equipped with a knife bar 23 for severing a paper web that is coming to an end.
- Above the parallel guide 14 are two guide rollers 26 fixed to the frame; 27, between which there is a dancer roller 28 which can be moved back and forth in the direction of arrow C.
- a paper web 24 thus runs in the representation shown in FIG. 1 in the preparation position from the paper roll 3 in the indicated arrow direction over the paper guide roller 6 fixed to the roller carrier, over the guide rollers 21 pivotably mounted about the axis of rotation 12 and about the lever 13; 22. If the pivotable support frame 7 is in the rest position B, which is shown in broken lines in FIG. 1, then the paper web 24 runs over the guide rollers 6; 26; 28; 27.
- FIG. 2 shows an enlarged illustration of the support frame 7 with the compensation device 15 in the preparation position and FIG. 3 shows the same picture, but in the working position.
- the guide rollers 21; 22 by means of axes 29; 31 stored.
- Two working cylinders 32 for example pneumatic working cylinders, only shown once, are each via their articulation points 33; 34 attached to the support frame 7 and the double-armed lever 13 near the axis 31 of the guide roller 22.
- the pneumatic working cylinder 32 has connecting pieces 36, the hoses and control arrangements with a central, not shown, not shown Compressed air supply system are connected.
- the working cylinder 32 is shown in Fig. 4 rotated by about 90 o for better understanding.
- a pneumatic working cylinder 37 with a connecting piece 38 is arranged between the articulation points 39 on the lever arm 13 in the vicinity of the guide roller 22 and the articulation points 41 on couplers 42.
- the couplers 42 shown only once, are non-rotatably connected to the guide roller carrying the knife bar 23.
- a gear motor (not shown) rotates the shaft 11 according to FIGS. 4 and 1.
- the shaft 11 is at its end with a gear 43 and a guide roller 44 provided.
- the gear 43 meshes in a rack 46 and the guide roller 44 runs in a guide rail 47 fixed to the frame; 48, so that the drive shaft 11 has taken the position 11.1 in the dashed rest position.
- the guide lever 16; 17 then also take the dashed position B of FIG. 1.
- the operation of the device is summarized as follows. From the rest position B, the support frame 7 is in time before the role change in Preparation position driven according to FIG. 2.
- a signal from the machine control (not shown) makes the working cylinder 32 effective and briefly presses the guide roller 22, which acts as an adhesive roller, according to the direction of the arrow E in FIG the pressing of the guide roller 22, the lever 13 is rotated about its axis of rotation 12, so that an increase in tension in the paper web 24 is avoided by the compensating movement of the guide roller 21 in the direction of arrow F.
- the guide roller 21 is subsequently moved by the working cylinder 37 so that the knife bar 23 knocks off the paper web of the paper roll 3 that is coming to an end, which is already glued to the beginning of the new paper roll 4, so that only the new paper roll 4 expires.
- the support frame 7 can be moved back with the compensation device 15 from the working position through the preparation position to the rest position B.
Description
Die Erfindung betrifft eine Vorrichtung zum Verbinden eines Anfanges einer rotierenden Reserve-Rest-Papierrolle mit einer sich bewegenden Papierbahn einer Rest-Papierrolle gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for connecting a beginning of a rotating reserve residual paper roll to a moving paper web of a residual paper roll according to the preamble of
Durch die US-A-1 967 056 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt.A device according to the preamble of
Entsprechend der DE-PS 8 78 945 ist eine Vorrichtung zum Ankleben einer neuen Bahn an eine ablaufende Papierbahn bekannt, indem die neue Papierrolle außen an ihrem Papierbahnanfang eine vorbereitete Klebespitze aufweist, die mit der ablaufenden Papierbahn der zu Ende gehenden Papierrolle durch andrückbare Bürstenelemente verbunden wird. Da während des Andrückvorganges zum Verbinden der beiden Papierbahnen eine Streckung der Papierbahn vermieden werden soll, die zum Abreißen des Papiers führen kann, sind gemäß o. g. DE-PS 8 78 945 zwei bewegliche Stangen oder Walzen vorgesehen. Während die eine Walze die ablaufende Papierbahn der zu Ende gehenden Papierrolle an den Anfang der neuen Papierrolle andrückt, wird eine andere Walze in der entgegengesetzten Richtung bewegt. Nachteilig an dieser Vorrichtung ist, daß die beiden Walzen eine relativ große Massenträgheit besitzen, die nicht in Bruchteilen von Sekunden zu überwinden ist, um den Anklebevorrichtung auszuführen, da bei der Papierdurchlaufgeschwindkeit der heutigen Hochleistungs-Rollenrotationsdruckmaschinen eine sehr begrenzte Zeit für den Anklebevorgangn zur Verfügung steht.According to DE-PS 8 78 945, a device for gluing a new web to a running paper web is known in that the new paper roll has a prepared adhesive tip on the outside at its beginning of the paper web, which is connected to the running paper web of the paper roll coming to an end by pressing brush elements . Since stretching of the paper web, which can lead to tearing of the paper, is to be avoided during the pressing process for connecting the two paper webs, two movable rods or rollers are provided according to the above-mentioned DE-PS 8 78 945. While one roller presses the running paper web of the end of the paper roll to the beginning of the new paper roll, another roller is moved in the opposite direction. A disadvantage of this device is that the two rollers have a relatively large mass inertia, which cannot be overcome in a fraction of a second, in order to carry out the gluing device, since the paper throughput speed of today's high-performance web-fed rotary printing presses allows a very limited time for the gluing processes .
Weiterhin ist entsprechend der DD-WP 86 409 eine Papierbahnanklebevorrichtung für Rotationsdruckmaschinen bekannt, bei der die ablaufende Bahn mit der neuen Rolle mittels einer Führungswalze in Berührung gebracht wird und gleichzeitig eine Andrückbürste zum Anpressen der ablaufenden Bahn an die vorbereitete Klebestelle der neuen Papierrolle sowie eine zweite Walze zum Ausgleichen der eingetretenenen Längenänderung der ablaufenden Bahn geschwenkt werden, wobei die Stellmittel der beiden Walzen und der Bürste miteinander gekoppelt sind in der Art, daß die Führungswalze, die Andrückbürste und die Ausgleichswalze mittels eines durch einen kurzzeitig zuschaltbaren Motor betätigten Schraubtriebes verstellt werden, welcher an einen auf der Bürstenwelle befestigten Hebel angreift, an den eine Stellstange zum Schwenken der Führungs- und Ausgleichswalze angelenkt ist.Furthermore, according to DD-WP 86 409, a paper web gluing device for rotary printing presses is known, in which the running web is brought into contact with the new roll by means of a guide roller and at the same time a pressure brush for pressing the running web against the prepared adhesive point of the new paper roll and a second Roller to compensate for the change in length of the running web occurred, the actuating means of the two rollers and the brush are coupled to one another in such a way that the guide roller, the pressure brush and the compensating roller are adjusted by means of a screw drive actuated by a briefly switchable motor, which engages on a lever attached to the brush shaft, to which an actuating rod is pivoted for pivoting the guide and compensating roller.
Nachteilig bei dieser Vorrichtung ist, daß ein großer Aufwand an Antriebs- und Übertragungselementen erforderlich ist, um die beiden Papierbahnen miteinander zu verbinden. Darüberhinaus weisen die Antriebselemente eine solche Massenträgheit auf, daß der Anklebevorgang bzw. Verbindungsvorgang der Papierbahnen in Zeiträumen erfolgt, die bei den heutigen Hochleistungs-Rollenrotationsdruckmaschinen bei einer Papierlaufgeschwindigkeit von 15 m/s und mehr, inakzeptabel sind.A disadvantage of this device is that a large amount of drive and transmission elements is required to connect the two paper webs to one another. In addition, the drive elements have such a mass inertia that the gluing or connecting process of the paper webs takes place in periods that are unacceptable in today's high-performance web-fed rotary printing press at a paper running speed of 15 m / s and more.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, bei der während des Verbindens zweier Papierbahnen beim Papierrollenwechselvorgang ein Ansteigen der Papierspannung weitgehendst vermieden werden kann.The invention has for its object to provide a generic device in which an increase in the paper tension can be largely avoided during the connection of two paper webs during the paper roll changing process.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of
Bei der Anwendung der Erfindung entstehen insbesondere folgende Vorteile. Die Papierbahnen werden ohne Änderung der Papierspannung infolge eines Papierlängenausgleiches miteinander verbunden, welcher zwangsläufig erfolgt, ohne daß ein hoher getriebetechnischer Aufwand betrieben werden muß. Ein Dehnen oder Reißen der Papierbahn, auch bei hohen Maschinengeschwindigkeiten, kann somit ausgeschlossen werden.The following advantages arise in particular when using the invention. The paper webs are connected to one another without changing the paper tension as a result of a paper length compensation, which inevitably takes place without the need for high expenditure on gear technology. Stretching or tearing of the paper web, even at high machine speeds, can thus be excluded.

Nach Fig. 1 befindet sich in einem Maschinengestell 1 ein Rollenträger 2, welcher eine ablaufende, d. h. zu Ende gehende Papierrolle 3 und eine neue Papierrolle 4 mit einer vorbereiteten Klebespitze trägt. Der Rollenträger 2 trägt weiterhin eine fest an einem Arm angeordnete Papierleitwalze 6 und ist drehbar gelagert.According to Fig. 1 is in a
Ein insgesamt mit 7 bezeichneter schwenkbarer Tragrahmen besitzt zwei zum Maschinengestell 1 parallel verlaufende Seitenteile 8; 9, von denen jedoch nur das Seitenteil 8 sichtbar ist. In axialer Richtung sind die Seitenteile 8; 9 über eine Drehachse 12 für einen doppelarmigen Hebel 13 einer insgesamt mit 15 bezeichneten Ausgleichseinrichtung, hier ohne Antrieb dargestellt, verbunden. Der Tragrahmen 7 ist über seine Antriebswelle 11 in einer gestellfesten Parallelführung, die insgesamt mit 14 bezeichnet ist, in eine gestrichelt dargestellte Ruhestellung B verfahrbar. Dazu sind noch Führungshebel 16; 17 an den Seitenteilen 8; 9 angelenkt, die an ihren entgegengesetzten Enden gestellfest gelagert sind. Durch einen noch näher zu beschreibenden Antrieb ist der Tragrahmen 7 um einen Winkel α von ca. 120o von der Vorbereitungsstellung in die Ruhestellung schwenkbar, so daß die Führungshebel 16; 17 sowie der Tragrahmen 7 die gestrichelte Stellung B einnehmen. Die genannten Teile 17 und 19 sind ebenfalls in Fig. 1 nicht sichtbar. Der doppelarmige Hebel 13 - zweimal vorhanden - ist über die Drehachse 12 mit den Seitenteilen 8; 9 verbunden und trägt an seinem dem Rollenträger 2 zugewandten Ende eine Leitwalze 21 und an seinem dem Rollenträger 2 abgewandten Ende eine Leitwalze 22. Die Leitwalze 22 dient als Klebewalze und die Leitwalze 21 kann mit einer Messerleiste 23 ausgestattet sein zum Durchtrennen einer zu Ende gehenden Papierbahn. Oberhalb der Parallelführung 14 sind noch zwei gestellfeste Leitwalzen 26; 27 angeordnet, zwischen denen sich eine in Pfeilrichtung C hin- und herbewegbare Tänzerwalze 28 befindet.A pivotable support frame, designated overall by 7, has two
Eine Papierbahn 24 läuft also in der nach Fig. 1 gezeigten Darstellung in der Vorbereitungsposition von der Papierrolle 3 in der angezeigten Pfeilrichtung über die rollenträgerfeste Papierleitwalze 6, über die um die Drehachse 12 und über die Hebel 13 schwenkbar gelagerten Leitwalzen 21; 22. Befindet sich der schwenkbare Tragrahmen 7 in Ruhestellung B, welche in Fig. 1 gestrichelt dargestellt ist, dann erfolgt der Lauf der Papierbahn 24 über die Leitwalzen 6; 26; 28; 27.A
Die Fig. 2 zeigt eine vergrößerte Darstellung des Tragrahmens 7 mit der Ausgleichseinrichtung 15 in der Vorbereitungsstellung und Fig. 3 zeigt das gleiche Bild, jedoch in Arbeitsstellung. In den doppelarmigen Hebeln 13 sind die Leitwalzen 21; 22 mittels Achsen 29; 31 gelagert. Zwei Arbeitszylinder 32, beispielsweise pneumatische Arbeitszylinder, einmal nur dargestellt, sind jeweils über ihre Anlenkpunkte 33; 34 auf dem Tragrahmen 7 und dem doppelarmigen Hebel 13 in der Nähe der Achse 31 der Leitwalze 22 befestigt. Der pneumatische Arbeitszylinder 32 besitzt Anschlußstutzen 36, die über nicht dargestellte Schläuche und Steueranordnungen mit einer nicht dargestellten zentralen Druckluftversorgungsanlage verbunden sind. Der Arbeitszylinder 32 ist in Fig. 4 zum besseren Verständnis um ca. 90o gedreht dargestellt. Durch Betätigung der Arbeitszylinder 32 wird der Abstand d nach Fig. 2 zwischen der als Kleberolle dienenden Leitwalze 22 und der neuen Papierrolle 4 überwunden und die in Fig. 3 gezeigte Arbeitsstellung eingenommen. Zur Betätigung der Messerleiste 23 an der Leitwalze 21 ist jeweils ein pneumatischer Arbeitszylinder 37 mit Anschlußstutzen 38 zwischen den Anlenkpunkten 39 auf dem Hebelarm 13 in der Nähe der Leitwalze 22 und den Anlenkpunkten 41 auf Koppeln 42 angeordnet. Die Koppeln 42, nur einmal dargestellt, sind mit der die Messerleiste 23 tragenden Leitwalze drehfest verbunden.FIG. 2 shows an enlarged illustration of the
Soll nun die Ruhestellung B des Tragrahmens 7 in der gestrichelten Lage nach Fig. 1 eingenommen werden, so dreht ein nicht dargestellter Getriebemotor die Welle 11 nach Fig. 4 und 1. Die Welle 11 ist an ihren Ende jeweils mit einem Zahnrad 43 und einer Führungsrolle 44 versehen. Das Zahnrad 43 kämmt in einer Zahnstange 46 und die Führungsrolle 44 läuft in einer gestellfesten Führungsschiene 47; 48, so daß die Antriebswelle 11 in gestrichelter Ruhestellung die Position 11.1 eingenommen hat. Die Führungshebel 16; 17 nehmen dann ebenfalls die gestrichelte Position B nach Fig. 1 ein.If the rest position B of the
Die Funktionsweise der Vorrichtung ist zusammengefaßt wie folgt. Aus der Ruhestellung B wird der Tragrahmen 7 rechtzeitig vor dem Rollenwechsel in die Vorbereitungsstellung nach Fig. 2 gefahren. Durch ein Signal aus der nicht dargestellten Maschinensteuerung wird der Arbeitszylinder 32 wirksam und drückt die als Klebewalze fungierende Leitwalze 22 gemäß Pfeilrichtung E nach Fig. 3 kurzzeitig an die ablaufende Papierbahn 24 und gegen die vorbereitete Klebespitze der ebenfalls auf entsprechende Umlaufgeschwindigkeit gebrachten neuen Papierrolle 4. Durch das Andrücken der Leitwalze 22 wird der Hebel 13 um seine Drehachse 12 gedreht, so daß durch die Ausgleichsbewegung der Leitwalze 21 in Pfeilrichtung F ein Spannungsanstieg in der Papierbahn 24 vermieden wird. Die Leitwalze 21 wird nachfolgend durch die Arbeitszylinder 37 bewegt, so daß die Messerleiste 23 die Papierbahn der zu Ende gehenden Papierrolle 3, die bereits mit dem Anfang der neuen Papierrolle 4 verklebt ist, abschlägt, so daß nur noch die neue Papierrolle 4 abläuft. Nun kann der Tragrahmen 7 mit der Ausgleichseinrichtung 15 wieder von der Arbeitsstellung über die Vorbereitungsstellung zur Ruhestellung B zurückgefahren werden.The operation of the device is summarized as follows.
