Abstract

Apparatus for splicing the end of a terminating reel to the outer layer of a subsequent reel: a splicing tube is either swingable or reciprocable to move between a waiting position out of contact with the strip to be cut and an operating position where the splicing tube moves transversely to and into contact with the strip and moves the strip to a position where it can be cut by a knife. A knife movable between a waiting position where it will not cut the strip and a cutting position where movement of the splicing tube to the operating position moves the strip to contact the knife for cutting. The knife is supported to be moved between its positions either by swinging or by movement along a guide path. The splicing tube includes a vacuum zone which holds the strip to it, and the splicing tube is rotatable on its axis for maintaining the tension of the strip.

Description

Die Erfindung betrifft eine Einrichtung entsprechend dem Oberbegriff des Patentanspruchs 1. Eine solche Einrichtung ist bekannt aus der EP 462 157 B1. Bei dieser Einrichtung befindet sich ein Trennmesser auf der Splicevorrichtung, die als ein schlanker Hohlzylinder ausgebildet ist und eine Saugzone aufweist. Dabei ist das Trennmesser in einer Nut angeordnet, die in dem Spliceelement ausgebildet ist. Das Trennmesser hat eine eigene Betätigungsvorrichtung, die beim Trennvorgang in Bewegung gesetzt wird. Es ergibt sich dadurch natürlich ein relativ komplizierter Aufbau des Spliceelements mit einer relativ starken Schwächung desselben in beanspruchungsmäßiger Hinsicht, weil die Nut den zylindrischen Mantel unterbricht.The invention relates to a device according to the preamble of Claim 1 Such a device is known from EP 462 157 B1. With this device there is a cutting knife on the Splicing device, which is designed as a slim hollow cylinder and a Has suction zone. The cutting knife is arranged in a groove that in the splice element is formed. The cutting knife has its own Actuator that is set in motion during the cutting process. It this naturally results in a relatively complicated structure of the Splice elements with a relatively strong weakening of the same in in terms of stress, because the groove the cylindrical shell interrupts.

DE 34 40 107 C2 beschreibt eine Einrichtung zum Verbinden des Endes einer ablaufenden Materialbahn mit dem Anfang einer zweiten Materialbahn. Dabei ist ein vom Spliceelement getrennt angeordnetes Messer vorgesehen, das gegen einen gespannten Bahnabschnitt bewegt wird. DE 39 01 854 A1 beschreibt eine ähnliche Vorrichtung, bei welcher die Bahn gegen die Schneide einer Schneidvorrichtung bewegt wird; die Schneidvorrichtung und das Spliceelement sind dabei voneinander getrennt angeordnet.DE 34 40 107 C2 describes a device for connecting the end of one running material web with the beginning of a second material web. Here a knife arranged separately from the splice element is provided, which is moved against a stretched track section. DE 39 01 854 A1 describes a similar device in which the web against the Cutting edge of a cutting device is moved; the cutting device and the splice element are arranged separately from one another.

EP-A-0 299 180 offenbart eine Vorrichtung zum Verbinden des Bahnendes einer auslaufenden Wickelrolle mit der äußeren Lage einer nachfolgenden Wickelrolle im Ruhezustand, mit einem perforierten Splicerohr. Gemäß diesem Dokument ist zwar das Splicerohr um die eigene Achse verdrehbar. Von einem eigenen Antrieb ist jedoch nicht die Rede. Jenes Splicerohr ist somit nicht willkürlich winkelpositionierbar. EP-A-0 299 180 discloses an apparatus for connecting the web end an outgoing winding roll with the outer layer of a subsequent one Idle reel with a perforated splicer tube. According to this The splicer tube can be rotated around its own axis. Of however, there is no question of an independent drive. That splicer tube is thus not arbitrarily angularly positionable.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1 derart zu gestalten, daß die Bahn während des Splicevorganges strammgehalten wird, so daß der Splicevorgang zu einem erfolgreichen Ergebnis führt.The invention has for its object a device according to the Preamble of claim 1 to be designed such that the web during the Splicing is held tight, so that the splicing to a successful result.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Nachfolgend wird die Erfindung anhand der Figuren der Zeichnung erläutert, welche jeweils eine Seitenansicht, zum Teil ausschnittweise, der verschiedenen Erfindungsvarianten in prinzipieller Darstellung wiedergeben.The invention is explained below with reference to the figures of the drawing, each of which is a side view, partly in section, of reproduce different variants of the invention in principle.

Der Tambour ist mit zwei Kreisen 1 und 1' strichpunktiert dargestellt, wobei der Tambour 1' den größtmöglichen Umfang hat. Die vom alten, jetzt ruhig gestellten, Bahnwickel 9 abgelaufene Bahn ist mit T bezeichnet. Sie wird durch das Spliceelement 2 aus der ausgezogen dargestellten Stellung in die strichpunktierte Stellung bei der Schwenkbewegung desselben mitgenommen. Diese Schwenkbewegung wird durch Schwenkarme 3 ermöglicht, die an dem Ständer 12 befestigt sind, der auch die erste Umlenkwalze 5 für die Bahn trägt. Weitere Umlenkwalzen 21 und 22 leiten die Bahn weiter. Die Trennvorrichtung ist mit 10 angegeben, wobei eine Schneide 11 und ein Betätigungsantrieb 15 z.B. in Form eines hydraulischen Hubwerkes vorgesehen ist. In der Figur ist die Trennvorrichtung in der Arbeitsposition gezeichnet, in welcher die Durchtrennung der Bahn bei ruhender Schneide bzw. Messervorrichtung durch die gespannte Bahn selbst erfolgt. Dies ist auch die eine Arbeitsposition des Spliceelements 2, das als rohrförmiger Zylinder angedeutet ist und eine Saugzone 4 in Form eines durchlöcherten Mantels aufweist. Beim Saugvorgang wird das Innere des Rohres unter Unterdruck gesetzt. Der zugehörige Unterdruckanschluß ist hier nicht dargestellt. Es ist eine weitere Arbeitsposition angegeben, bei welcher das Spliceelement - gestrichelt ausgeführt - an dem Bahnwickel 1 kleineren Durchmessers anliegt. Die oberste Position des Spliceelements ist die Warteposition, in welcher dieses in seiner Ausgangsstellung verharrt. Durch Herabschwenken des Spliceelements aus dieser Position in die untere Arbeitsposition entlang dem Bogen S wird die Bahn eingefangen, indem sie sich an die Saugzone des Spliceelements anlegt. Dann kann der Trennvorgang durch das Messer 11 erfolgen, wobei dieses jedoch schon vorher in diese Arbeitsposition gebracht werden muß, in welcher es dann einige Zeit bis zum Trennvorgang verharrt.The drum is shown with two circles 1 and 1 'in dash-dot lines, whereby the drum 1 'has the largest possible extent. The old one, now calm provided, web winding 9 expired web is denoted by T. she will by the splice element 2 from the position shown in the extended position dash-dotted position when swiveling the same taken away. This swiveling movement is carried out by swivel arms 3 allows, which are attached to the stand 12, which is also the first Deflection roller 5 carries for the web. Further deflecting rollers 21 and 22 guide the Train on. The separating device is indicated by 10, with one cutting edge 11 and an actuator 15 e.g. in the form of a hydraulic Hoist is provided. In the figure, the separator is in the Working position drawn in which the cut of the web at stationary cutting edge or knife device through the tensioned web itself he follows. This is also the one working position of the splice element 2, which as tubular cylinder is indicated and a suction zone 4 in the form of a perforated jacket. During the suction process, the inside of the Pipe under negative pressure. The associated vacuum connection is here not shown. Another working position is given, in which the splice element - dotted - on the web wrap 1 smaller diameter is present. The top position of the Splice elements is the waiting position in which this is in remains in its original position. By swinging the Splice elements from this position to the lower one Working position along the arch S becomes the web trapped by the suction zone of the Splice elements created. Then the separation process by the Knives 11 take place, but this is previously in this working position must be brought in which it then remains for some time until the separation process.

Beim Hochschwenken des Spliceelements 2 in die weitere Arbeitsposition, in welcher der Splicevorgang stattfindet, kann vorzugsweise das Spliceelement um seine eigene Achse durch einen entsprechenden Antrieb verdreht werden, so daß die Bahn während dieses Vorganges strammgehalten bleibt. Das Spliceelement wird in die obere, ausgezogen dargestellte End- oder Warteposition zurückgeschwenkt, dann der neue Tambour durch eine bekannte, hier aber nicht dargestellte Transportvorrichtung an die Stelle des alten Bahnwickels 9 in die übliche Halterung eingelegt und dann der Splicevorgang durch Anlegen des Spliceelements 2 an den Umfang des neuen Tambours durchgeführt. Für diesen Zweck weist die letzte Windung des neuen Tambours natürlich an dieser Splicestelle einen Klebeauftrag, z.B. in Form eines doppelseitigen Klebestreifens, auf. Die Bahn T' verläuft dann im wesentlichen in horizontaler Richtung zur ersten Umlenkrolle 5 hin.When swiveling the splice element 2 into the other Working position in which the splicing process takes place, can preferably the splice element about its own axis be rotated by an appropriate drive so that the web remains taut during this process. The splice element is pulled out into the upper one shown end or waiting position swung back, then the new drum through a familiar one, but not here shown transport device in the place of the old Web winding 9 placed in the usual holder and then the splicing process by applying the splice element 2 to the Scope of the new drum performed. For this purpose of course instructs the last turn of the new drum an adhesive application to this splice, e.g. in form of double-sided adhesive tape. The path T 'runs then essentially in the horizontal direction to the first Deflection roller 5 out.

Man erkennt, daß die Einrichtung relativ einfach aufgebaut ist, und daß auch der hier angegebene maximale Schwenkbereich der Schwenkarme 3 durch eine entsprechende Hubvorrichtung 14 - z.B. hydraulischer Art - ohne weiteres durchführbar ist. Eine ähnliche Anordnung ergibt sich bei umgekehrten Bahnablauf von Tambour und altem Bahnwickel im Fall einer entgegengesetzten Wickelrichtung derselben. It can be seen that the device is relatively simple and that also the maximum specified here Swivel range of the swivel arms 3 by a corresponding one Lifting device 14 - e.g. hydraulic type - without further ado is feasible. A similar arrangement results from reverse course of the reel and the old reel in In the case of an opposite winding direction of the same.

Die in Figur 2 dargestellte erfindungsgemäße Anordnung entspricht im Prinzip derjenigen von Figur 1. Im wesentlichen geändert worden ist nur die Messervorrichtung. Zur Lagerung der Messervorrichtung sind hier jeweils ein Ständer 24 neben dem Tambour vorgesehen, die sich entfernt von dem Abrollgestell 41 mit der Lagerung 36 des jeweiligen Tambours befinden. Die Messervorrichtung besteht aus dem Messer 11, einem langgestreckten, stab- oder balkenförmigen Träger 31 und Seitenträgern 25, die den langgestreckten Träger 31 halten. Der Träger 31 erstreckt sich längs des Tambours ebenso wie das Messer 11'. Die Seitenträger 25 sind hier mittels Rollen 29 und 30 in den Führungsbahnen 27 der Ständer 24 geführt. Der Antrieb erfolgt über eine Kette 34 und eines der Kettenräder 32 und 33 über einen hier nicht dargestellten Antriebsmotor, z.B. einen Elektromotor. Das obere Ende der Führungsbahn 27 und dementsprechend die Schneidposition des Messers 11' befindet sich oberhalb der durch die Tambourachse verlaufenden Horizontalebene H. Auch hier wird der Schneidvorgang durch das Herabschwenken der Splicevorrichtung 2 in die hier angegebene untere Position im wesentlichen allein durch die Bahnspannung bewirkt. Weitere Einzelheiten der Hilfseinrichtungen zur Bewegung des Tambours sind hier ebenfalls in Figur 1 nicht dargestellt. Zu erwähnen ist noch, daß das Abrollgestell 41 auf einer Grundplatte 42 des Fundaments ruht.The arrangement according to the invention shown in Figure 2 corresponds in principle to that of Figure 1. Im only the knife device has been significantly changed. There are one for storing the knife device Stand 24 is provided next to the drum, which moves away from the unwind stand 41 with the bearing 36 of the respective Drums are located. The knife device consists of the Knife 11, an elongated, rod or bar-shaped Beam 31 and side beams 25, which are elongated Hold carrier 31. The carrier 31 extends along the Drums as well as the knife 11 '. The side straps 25 are here in the guideways 27 by means of rollers 29 and 30 the stand 24 out. The drive takes place via a chain 34 and one of the sprockets 32 and 33 via one here Drive motor, not shown, e.g. an electric motor. The upper end of the guideway 27 and, accordingly, the Cutting position of the knife 11 'is above the through the horizontal axis H. Also running here is the cutting process by swiveling the Splicing device 2 in the lower position specified here caused essentially solely by the web tension. Further details of auxiliary devices for movement of the drum are also not shown in Figure 1 shown. It should also be mentioned that the unwind frame 41st rests on a base plate 42 of the foundation.

In Figur 3 ist eine ähnliche Antriebseinrichtung für die Messervorrichtung dargestellt, wobei auch hier eine Kette, ein Seil oder auch ein Zahnriemen 40 benutzt werden kann. Der Antrieb erfolgt hier jedoch über einen hydraulischen oder pneumatischen Stellzylinder 39 und einen Hebel 38, der jeweils an den Seitenträgern 25 der Messervorrichtung befestigt ist.In Figure 3 is a similar drive device for the Knife device shown, here also a chain, a rope or a toothed belt 40 can be used. However, the drive is via a hydraulic one or pneumatic actuating cylinder 39 and a lever 38, the each on the side supports 25 of the knife device is attached.

In den Figuren 2 und 3 ist mit Winkel a der günstige Bereich zum Anbringen des Klebestreifens für den Splicevorgang angedeutet. Im wesentlichen verlaufen die Führungsbahnen 27, 27' und auch die Ständer 24 vertikal, vorzugsweise höchstens 30° von der Vertikalen abweichend. Dadurch wird eine sehr raumsparende Anordnung erzielt, was bei beengten Raumverhältnissen z.B. durch die Art der Ausbildung der Abrollständer günstig ist. Daher befinden sich auch in günstiger Weise die Ständer 24 - in Richtung quer zum Tambour 1, 1' - entfernt von den Rollenständern 41.In Figures 2 and 3 with angle a is the favorable Area for attaching the adhesive strip for the Splicing indicated. Essentially, the Guideways 27, 27 'and also the stands 24 vertically, preferably deviating at most 30 ° from the vertical. This results in a very space-saving arrangement, what in confined spaces e.g. by the type of Training of the unwind stand is cheap. Therefore stand 24 - in a favorable manner across the drum 1, 1 '- away from the reel stands 41.

In Figur 4 ist eine ähnliche Einrichtung bezüglich der Messervorrichtung dargestellt wie in Figur 2. Hier ist jedoch ein anderer Antriebs des Spliceelements 2 vorgesehen. Und zwar wird hier über einen Halter 54 eine von einem Gleitschlitten 53 geführte Antriebsstange 50 von der Kolbenstange 52 eines hydraulischen oder pneumatischen Hubelements 51 betätigt. Die Führungsbahn des Gleitschuhs 53 ist mit 54 angedeutet. Das ganze wird von einer Konsole 56 mit Aufsatz 57 getragen. Diese ruht auf einem Ständer 12', der auch die erste Umlenkrolle 5' für die Bahn aufnimmt.In Figure 4 is a similar device with respect to Knife device shown as in Figure 2. Here is however, another drive of the splice element 2 intended. Namely, here is a holder 54 drive rod 50 guided by a slide 53 the piston rod 52 of a hydraulic or pneumatic Lifting element 51 actuated. The guideway of the slide shoe 53 is indicated with 54. The whole thing is from a console 56 worn with attachment 57. This rests on a stand 12 ', which is also the first pulley 5' for the web records.

In Figur 5 ist der Antrieb der Messervorrichtung gemäß Figur 2 wieder auf eine etwas andere Weise variiert. Die Seitenträger 25' für den balkenförmigen Messerträger 31 - hier als Rohr ausgebildet - gleiten auf Rollen 29' und 30' und werden über eine Verbindungslasche 67 von einem Führungswagen 60 angetrieben, der mittels Rollen 61 und 62 in den Führungsbahnen 27' des Ständers 59 an einer Kette 34' bewegt wird. Diese wird wiederum über ein hier nicht mehr erkennbares Kettenrad, das dem Kettenrad 33 entspricht, von einem Motor, z.B. einem Elektromotor, angetrieben. Der Ständer 59 erhält noch besondere Stabilität durch eine Versteifungsrippe 65. Die Seitenträger 25' weisen jeweils einen Fortsatz 66 auf, an welchem der Messerbalken 31 befestigt ist. Der Ständer 59 kann zu seinen beiden Seiten die Führungsbahnen 27' im wesentlichen bis zu der hier dargestellten oberen Position des Führungswagens 60 aufweisen, so daß jeweils zwei Rollenpaare 64 und 62 in diese Führungsbahnen eingreifen, so daß der Führungswagen 60 recht gut geführt ist.In Figure 5, the drive of the knife device according to Figure 2 again varies in a slightly different way. The Side carrier 25 'for the bar-shaped knife carrier 31 - here designed as a tube - slide on rollers 29 'and 30' and are connected by a connecting tab 67 from one Carriage 60 driven by means of rollers 61 and 62nd in the guideways 27 'of the stand 59 on a chain 34 'is moved. This in turn is not about a here more recognizable sprocket that the sprocket 33 from an engine, e.g. an electric motor, driven. The stand 59 receives even more special Stability thanks to a stiffening rib 65 Side supports 25 'each have an extension 66 which the cutter bar 31 is attached. The stand 59 can on both sides of the guideways 27 'in essentially up to the upper position shown here of the carriage 60, so that two Pairs of rollers 64 and 62 engage in these guideways, so that the carriage 60 is quite well managed.

Die in den Figuren 2-5 dargestellte Messerbetätigungseinrichtung hat den Vorteil, daß Hindernisse von dem Messer umgangen werden können, wobei in diesen Fällen das Hindernis praktisch der alte Bahnwickel 9 ist. Durch die Führungsbahnen kann eine recht günstige Schneidposition und kommt auf diese Weise sehr nahe an den oberen Umfangsbereich des Bahnwickels 9 heran, wenn es in seine Schneidposition gelangt ist.The one shown in Figures 2-5 Knife actuation device has the advantage that Obstacles can be avoided by the knife, being in In these cases the obstacle is practically the old web winding 9 is. Through the guideways can be quite cheap Cutting position and in this way comes very close to the upper circumferential region of the web winding 9 when it is in has reached its cutting position.
