Abstract

An arrangement for chopping of a web on a reversing winder having a blade carrying rail with cutting knife, which rail can be advanced to the web, and having a pressure device which can be advanced in each case to the empty winding tube, is to be further developed in such a manner that it is not just employable with tubes having a constant diameter. For this purpose, both the blade carrying rail (21) and the pressure device (27) having a frame (7, 10) movable relative to the winding tube (25; 25') are arranged in such a manner that the position thereof can be adjusted relative to the winding tube (25; 25') by moving the frame (7, 10). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Durchtrennen einer Bahn an einem Wendewickler mit einem an die Bahn zustellbaren Messerbalken mit Schneidmesser und einer jeweils an die leere Wickelhülse zustellbaren AndruckvorrichtungThe invention relates to a device for severing a web on a turret winder with a knife bar that can be fed to the web and has a cutting knife and a pressure device that can be fed to the empty winding tube

Wendewickler weisen in der Regel zwei Wickelhülsen auf, von de­nen jeweils eine in einer Aufwickelposition angeordnet ist. Nach Bildung eines fertigen Wickels wird die Hülse mit der aufge­wickelten Bahn aus ihrer Aufwickelposition in eine Entnahmeposi­tion verschwenkt, während gleichzeitig eine leere Hülse in die Aufwickelposition gebracht wird. Während des Verschwenkens der leeren und der aufgewickelten Hülse bleibt die Bahn mit der auf­gewickelten Hülse verbunden. Erst wenn die aufgewickelte Hülse in der Entnahmeposition und die leere Hülse in die Aufwickelposi­tion geschwenkt sind, wird die Bahn mit einem Schneidmesser durchtrennt und der nachlaufende Bahnanfang wird mit der leeren Hülse verbunden, so daß auf diese ein neuer Wickel aufgewickelt werden kann.Turret winders generally have two winding tubes, one of which is arranged in a winding position. After the formation of a finished roll, the sleeve with the wound web is pivoted from its winding position into a removal position, while at the same time an empty sleeve is brought into the winding position. During the pivoting of the empty and the wound sleeve, the web remains connected to the wound sleeve. Only when the wound core in the removal position and the empty core are pivoted into the winding position is the web cut with a cutting knife and the trailing web start is connected to the empty core, so that a new package can be wound onto it.

Bereits aus der US-PS 942 796 ist eine gattungsgemäße Vorrich­tung bekannt, bei der gleichzeitig die Bahn mit einem Messer durchtrennt wird und das vorlaufende Ende der neu aufzuwickeln­ den Bahn mit der noch leeren in die Aufwickelposition gebrachten Hülse verbunden wird. Zum Verbinden mit dem vorlaufenden Ende der Bahn ist die leere Hülse mit einem Klebstreifen versehen. An diesen wird das entsprechende Bahnende mittels eines direkt un­terhalb des Messers angeordneten Bleches an die Wickelhülse ange­drückt. Dieses Andrückblech wird also gleichzeitig mit dem Trenn­messer verschwenkt. Das Messer durchtrennt die Bahn unmittelbar neben der in die Aufwickelposition verschwenkte leeren Hülse.A generic device is already known from US Pat. No. 942,796, in which the web is simultaneously cut with a knife and the leading end of the rewind the web is connected to the still empty sleeve brought into the winding position. The empty sleeve is provided with an adhesive strip for connection to the leading end of the web. The corresponding end of the web is pressed onto the winding tube by means of a plate arranged directly below the knife. This pressure plate is pivoted simultaneously with the cutting knife. The knife cuts through the web immediately next to the empty tube pivoted into the winding position.

Eine derartige Einrichtung arbeitet solange zufriedenstellend, wie Hülsen mit einem einheitlichen Durchmesser eingesetzt wer­den. Werden aber beispielsweise Hülsen mit größerem Durchmesser eingesetzt, so schlagen die Messer in ihrer Durchtrennposition auf der Hülse auf. Diese vorbekannte Vorrichtung ist also für den Einsatz von Hülsen mit unterschiedlichem Durchmesser nicht geeignet.Such a device works satisfactorily as long as sleeves with a uniform diameter are used. If, for example, sleeves with a larger diameter are used, the knives will hit the sleeve in their severing position. This known device is therefore not suitable for the use of sleeves with different diameters.

Es stellt sich daher die Aufgabe, die gattungsgemäße Vorrichtung zum Durchtrennen einer Bahn an einem Wendewickler derart weiter­zubilden, daß diese automatisch auf unterschiedliche Hülsendurch­messer eingestellt werden kann.It is therefore the task of developing the generic device for severing a web on a turret winder in such a way that it can be automatically adjusted to different core diameters.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Dabei sind sowohl der das Schneidmesser tragende Messerbalken wie auch die Andruckeinrich­tung in einem relativ zur Wickelhülse verfahrbaren Rahmen derart angeordnet, daß deren Position bezüglich der Wickelhülsen gleich­zeitig mit Verfahren des Rahmens einstellbar ist.This object is achieved by the characterizing features of claim 1. Both the cutter bar carrying the cutting knife and the pressure device are arranged in a frame which can be moved relative to the winding tube in such a way that their position with respect to the winding tubes can be adjusted at the same time as the frame is moved.

Der Rahmen kann einfach aus einer Traverse und seitlichen Lager­platten bestehen. Dabei kann die Traverse über Rollen in einer gestellfesten Führungsschiene verlaufen. Der Rahmen kann in vor­teilhafter Weise über mindestens eine Kolben-Zylinder-Einheit verfahrbar sein.The frame can simply consist of a crossbeam and side bearing plates. The traverse can run over rollers in a guide rail fixed to the frame. The frame can advantageously be moved over at least one piston-cylinder unit.

Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Messerbalken über mindestens eine Kolben-Zylinder-Ein­heit zustellbar. Der den Messerbalken und die Kolben-Zylinder-­Einheit bzw. die Führungsteile des Messerbalkens betreffende Teil dar Vorrichtung ist gemäß dieser Ausführung über Bolzen in den Lagerplatten des verfahrbaren Rahmens drehbar gelagert, wo­bei am freien Ende der Bolzen Hebel drehfest angeordnet sind, deren freien Enden Führungsrollen tragen. Diese Führungsrollen sind abhängig von der Position des verfahrbaren Rahmens entlang Schrägflächen von gestellfesten Führungsteilen derart geführt, daß der Messerbalken abhängig von der Position des verfahrbaren Rahmens um den Bolzen verschwenkt wird. Dadurch kann in beson­ders einfacher Weise die auf den Durchmesser der Wickelhülse ab­gestimmte Ausgangsposition für das an dem Messerbalken angeordne­te Schneidmesser eingestellt werden.According to a particularly advantageous embodiment of the invention, the cutter bar can be advanced via at least one piston-cylinder unit. The part of the device relating to the cutter bar and the piston-cylinder unit or the guide parts of the cutter bar is rotatably mounted according to this embodiment by means of bolts in the bearing plates of the movable frame, with levers arranged in a rotationally fixed manner at the free end of the bolts, the free ends of which guide rollers wear. Depending on the position of the movable frame, these guide rollers are guided along inclined surfaces of guide parts fixed to the frame such that the cutter bar is pivoted about the bolt depending on the position of the movable frame. As a result, the starting position for the cutting knife arranged on the cutter bar can be adjusted in a particularly simple manner to the diameter of the winding tube.

Damit die Führungsrollen der Hebel an den Schrägflächen der ge­stellfesten Führungsteile anliegen, sind mit den Bolzen gemäß einer weiteren vorteilhaften Ausführung Lenker drehfest verbun­den, an denen Zugfedern angreifen, die die Führungsrollen stets gegen die Schrägflächen drücken.So that the guide rollers of the levers rest on the inclined surfaces of the guide parts fixed to the frame, according to a further advantageous embodiment, links are rotatably connected to the bolts, on which tension springs act, which always press the guide rollers against the inclined surfaces.

Die Andruckvorrichtung kann vorteilhaft aus einer die Bahn füh­renden Walze bestehen. Dabei kann diese über mindestens eine Kol­ben-Zylinder-Einheit zustellbar sein, wobei der bzw. die Zylin­der fest auf der verfahrbaren Traverse montiert ist bzw. sind. Auch die Andruckvorrichtung kann über Rollen in der gestell­festen Führungsschiene verschiebbar gelagert sein.The pressure device can advantageously consist of a roller guiding the web. In this case, this can be delivered via at least one piston-cylinder unit, the cylinder or cylinders being or are permanently mounted on the movable crossmember. The pressure device can also be slidably mounted on rollers in the guide rail fixed to the frame.

Damit die Bahn während des Verschwenkens der fertig aufgewickel­ten Wickelhülse und der noch leeren Wickelhülse nicht an der mit Klebstoff beschichteten noch leere Wickelhülse anliegt, kann die­se über eine der als Andruckvorrichtung dienenden Walze nachge­schaltete Umlenkwalze geführt werdenSo that the web does not lie against the still empty winding sleeve coated with adhesive during the pivoting of the wound winding sleeve and the still empty winding sleeve, this can be guided over a deflection roller downstream of the roller serving as a pressing device

Further details and advantages of the invention are explained in more detail with reference to an embodiment shown in the drawing. Show:
  • 1 is a top view of the severing and adjusting devices of a turret winder,
  • Fig. 2 shows a section through the severing and adjusting devices along the section line II-II of Fig. 1 and
  • Fig. 3 shows part of the cutting device of a winder with associated turning disc and two winding stations.

An der Innenseite der beiden Seitengestelle 1 eines Wendewick­lers sind Führungsschienen 2 und 3 befestigt sind. Die rechte Seite der Fig. 1 zeigt die Führungsschiene 2 geschlossen, wäh­rend die linke Seite der Fig. 1 die Führungsschiene im Schnitt darstellt. In den Führungsschienen laufen Rollen 4, die über Zap­fen 5 mit Platten 6 verbunden sind. Diese Platten 6 sind stirn­seitig mit einer Traverse 7 verschweißt, wobei an der Traverse 7 Kolben-Zylinder-Einheiten 8 angreifen, die ihrerseits über Wickel 9 mit den Seitenwänden 1 fest verbunden sind. Über diese Kolben-Zylinder-Einheiten 8 kann die Traverse 7 in Pfeilrichtung A hin und her bewegt werden.Guide rails 2 and 3 are fastened to the inside of the two side frames 1 of a turret winder. The right side of FIG. 1 shows the guide rail 2 closed, while the left side of FIG. 1 shows the guide rail in section. Rollers 4 run in the guide rails and are connected to plates 6 via pins 5. These plates 6 are welded on the end face to a crossmember 7, with piston-cylinder units 8 acting on the crossmember 7, which in turn are firmly connected to the side walls 1 via windings 9. The crossbeam 7 can be moved back and forth in the direction of arrow A via these piston-cylinder units 8.

Im Bereich der Platten 6 sind mit der Traverse 7 Lagerplatten 10 fest verschweißt, die, wie die Fig. 2 zeigt, in ihrem vorderen Ende gabelförmig ausgebildet sind. In den der Traverse 7 abge­wandten Enden der oberen Plattenteile sind Bolzen 11 frei dreh­bar gelagert, auf deren nach außen weisenden Enden Hebel 12 auf­geklemmt sind. Die freien Enden dieser Hebel tragen je eine Füh­ rungsrolle 13, die je nach eingestelltem Zylinderhub der Kolben-­Zylinder-Einheiten 8 mehr oder weniger auf die Schrägflächen 14 von Führungsteilen 15 auflaufen. In dem dargestellten Ausfüh­rungsbeispiel sind die Kolbenstangen der Kolben-Zylinder-Einhei­ten 8 zur Ganze ausgefahren. Damit haben auch die Führungsrollen 13 die höchste Stelle der Schrägflachen 14 erreicht. Dies bedeu­tet, daß die Bolzen 11 bezogen auf Fig. 2 im Uhrzeigersinn ver­schwenkt worden sind.In the area of the plates 6, bearing plates 10 are firmly welded to the crossmember 7 and, as shown in FIG. 2, are fork-shaped in their front end. In the ends of the upper plate parts facing away from the crossbeam 7, bolts 11 are freely rotatably mounted, on the outwardly facing ends of which levers 12 are clamped. The free ends of these levers each carry a guide tion roller 13, depending on the set cylinder stroke of the piston-cylinder units 8 more or less on the inclined surfaces 14 of guide members 15. In the illustrated embodiment, the piston rods of the piston-cylinder units 8 are extended as a whole. So that the guide rollers 13 have reached the highest point of the inclined surfaces 14. This means that the bolts 11 have been pivoted clockwise with respect to FIG. 2.

Mit den Bolzen 11 sind Lenker 16 fest verbunden, an denen Zugfe­dern 17 angreifen, die die Führungsrollen 13 stets gegen die Schrägflächen 14 drücken. Die den Hebeln 12 gegenüberliegenden Enden der Bolzen 11 sind über Konsolen 18 mit Kugelbuchsen 19 fest verbunden, deren geführte Stangen 20 einendig den Messerbal­ken 21 tragen. Über mit den Kugelbuchsen 19 verbundenen Kolben-­Zylinder-Einheiten 22 kann der Messerbalken 21 und damit das Mes­ser 23 aus der in Fig. 2 mit B bezeichneten Lage in die in Fig. 2 mit C bezeichnete Lage verfahren werden, wodurch dann die Bahn 24 schlagartig durchtrennt wird.Handlebars 16 are fixedly connected to the bolts 11, on which tension springs 17 act, which always press the guide rollers 13 against the inclined surfaces 14. The ends of the bolts 11 opposite the levers 12 are firmly connected via brackets 18 to ball bushings 19, the guided rods 20 of which carry the cutter bar 21 at one end. By means of piston-cylinder units 22 connected to the ball bushings 19, the cutter bar 21 and thus the cutter 23 can be moved from the position labeled B in FIG. 2 to the position labeled C in FIG. 2, whereby the web 24 then suddenly is severed.

Um dabei den nachlaufenden Bahnanfang an die mit Klebstoff vorbe­reitete Hülse 25 mit Sicherheit ankleben zu können, werden die die Bahn 24 führenden Walzen 26 und 27 gleichzeitig mit dem Aus­fahren des Messers 23 aus der in Fig. 2 dargestellten Lage so weit in Richtung der Hülse 25 bewegt, bis die Walze 27 die Bahn 24 an die vorbereitete Hülse 25 andrückt. Zu diesem Zweck sind die Achsen 28 und 29, auf denen die Walzen 26 und 27 frei dreh­bar gelagert sind, in Haltern 30 undrehbar befestigt. Auf die frei auslaufenden Enden der Achsen 28 und 29 sind Rollen 31 frei drehbar gelagert, die in den Führungsschienen 2 laufen. Über Kol­ben-Zylinder-Einheiten 32 sind die Halter 30 mit der Traverse 7 verbunden, so daß die Halter 30 und demnach auch die Walzen 26 und 27 bei Betätigung der Kolben-Zylinder-Einheiten 32 gegenüber der Traverse 7 verstellt werden können.In order to be able to glue the trailing web start to the sleeve 25 prepared with adhesive with certainty, the rollers 26 and 27 guiding the web 24 become so far in the direction of the sleeve 25 at the same time as the knife 23 moves out of the position shown in FIG. 2 moves until the roller 27 presses the web 24 against the prepared sleeve 25. For this purpose, the axes 28 and 29, on which the rollers 26 and 27 are freely rotatably mounted, are non-rotatably fastened in holders 30. Rollers 31, which run in the guide rails 2, are freely rotatably mounted on the free ends of the axes 28 and 29. The holders 30 are connected to the cross member 7 via piston-cylinder units 32, so that the holders 30 and accordingly also the rollers 26 and 27 can be adjusted relative to the cross member 7 when the piston-cylinder units 32 are actuated.

Im folgenden wird die Funktion des zuvor beschriebenen Ausfüh­rungsbeispiels erläutert. In den Figuren ist die Position eines Wicklers dargestellt, in der ein Wickel 33 seinen gewünschten Durchmesser erreicht hat. Die Wendescheibe 34 ist soweit ver­schwenkt worden, daß die zweite Wickelstelle mit der vorbereite­ten Hülse 25 in die Nähe der Bahn 24 geschwenkt worden ist, die über eine Umlenkwalze 35 so geführt ist, daß die Bahn 24 die mit Leimstreifen vorbereitete Hülse 25 noch nicht berührt. In dieser Position befinden sich die Walzen 26 und 27 in der in den Figu­ren dargestellten Lage und das Messer in seiner Position B. Da­nach werden die Kolben-Zylinder-Einheiten 22 und 32 gleichzeitig betätigt, wodurch sich das Messer aus seiner Position B in die Position C verschiebt und dabei die Bahn 24 durchtrennt. Das ab­getrennte vorlaufende Ende der Bahn 24 wird dabei durch die Wal­ze 27 an die vorbereitete Hülse 25 angedrückt, wodurch auf die­ser Hülse 25 dann ein neuer Wickel gebildet wird. Nachdem dies geschehen ist, fahren die Kolben-Zylinder-Einheiten 22 und 32 wieder ein, wobei etwa gleichzeitig auch die Kolben-Zylinder-Ein­hieiten betätigt werden, durch die über die Traverse 7 die ge­samte Schneideinrichtung von der Wickelhülse 25 wegbewegt wird, so daß hier, ungehindert von der Schneideinrichtung, ein Wickel gebildet werden kann, so daß für das Herausnehmen des fertigen Wickels 33 genügend Zeit vorhanden ist.The function of the previously described exemplary embodiment is explained below. The figures show the position of a winder in which a winder 33 has reached its desired diameter. The turning disc 34 has been pivoted so far that the second winding point with the prepared sleeve 25 has been pivoted into the vicinity of the web 24, which is guided over a deflection roller 35 so that the web 24 does not yet touch the sleeve 25 prepared with glue strips. In this position, the rollers 26 and 27 are in the position shown in the figures and the knife in its position B. Then the piston-cylinder units 22 and 32 are actuated simultaneously, causing the knife to move from its position B to the position C shifts, cutting the web 24. The separated leading end of the web 24 is pressed against the prepared sleeve 25 by the roller 27, whereby a new roll is then formed on this sleeve 25. After this has been done, the piston-cylinder units 22 and 32 retract again, the piston-cylinder units being actuated approximately simultaneously, by means of which the entire cutting device is moved away from the winding tube 25 via the crossmember 7, so that here , unhindered by the cutting device, a winding can be formed so that there is sufficient time for removing the finished winding 33.

Soll nun statt der Wickelhülse 25 eine Wickelhülse größeren Durchmessers, nämlich die Wickelhülse 25′ (mit strichpunktierten Linien in Fig. 2 dargestellt) eingesetzt werden, werden über nicht dargestellte Initiatoren gesteuert, die Kolben-Zylinder-­Einheiten 8 nur so weit ausgefahren, daß die Führungsrollen 13 gerade eben auf die Führungsflächen 14 aufgelaufen sind. Diese Position der Führungsrollen 13 ist in Fig. 2 mit strichpunktier­ten Linien dargestellt und mit der Positionszahl 36 versehen. Die Bolzen 11 sind folglich bei der größten einzusetzenden Wickelhülse 25′ nicht mehr im Uhrzeigersinn verdreht worden. Zu der Lage der Führungsrollen 13, deren Position mit 36 bezeichnet ist, gehört die mit der Positionszahl 37 dargestellte Lage des Messerträgers 21 und des mit diesem verbundenen Messers 23. Die ausgefahrene Position des Messerbalkens 21 aus der mit dem Posi­tionszeichen 37 dargestellten Lage ist mit dem Positionszeichen 38 bezeichnet. Hieraus erkennt man, daß der Schnitt wiederum na­he der eingesetzten Hülse 25′ erfolgt.If, instead of the winding tube 25, a winding tube of larger diameter, namely the winding tube 25 '(shown with dash-dotted lines in Fig. 2) are used, are controlled by initiators, not shown, the piston-cylinder units 8 only extended so far that the Guide rollers 13 have just just run onto the guide surfaces 14. This position of the guide rollers 13 is shown in FIG. 2 with dash-dotted lines and provided with the position number 36. The bolts 11 are consequently the largest to be used Winding sleeve 25 'has no longer been rotated clockwise. The position of the guide rollers 13, the position of which is denoted by 36, includes the position of the knife holder 21 and the knife 23 connected to the position number 37. The extended position of the knife bar 21 from the position shown by the position symbol 37 is indicated by the Position symbol 38 denotes. From this it can be seen that the cut again takes place near the inserted sleeve 25 '.

Der Hub der Kolben-Zylinder-Einheiten 32 braucht dabei nicht ein­gestellt werden, weil es sich bei den Kolben-Zylinder-Einheiten um pneumatische Kolben-Zylinder-Einheiten handelt, deren Kolben­stangen so weit ausfahren, bis sich die Walze 27 gegen eine Wickelhülse, sei es die Wickelhülse 25 oder die Wickelhülse 25′, anlegt.The stroke of the piston-cylinder units 32 does not need to be adjusted because the piston-cylinder units are pneumatic piston-cylinder units, the piston rods of which extend until the roller 27 is against a winding tube it applies the winding tube 25 or the winding tube 25 '.
