Definitions
- the invention relates to a device for splicing webs, in particular paper webs for the production of corrugated cardboard with the features of the preamble of patent claim 1.
- Such a device for splicing webs is known from DE-A-38 16 223.
- the webs to be spliced are drawn off from two web rolls arranged on an interchangeable stand.
- the running web is guided around a vertically movable pressure and deflection roller and runs out via a storage loop to a subsequent work station.
- the beginning of the new web to be tied is fastened to a holding roller in the starting position and trimmed by a knife.
- the start of the web is held and transferred to a working position under one of two pressure and deflection rollers.
- After holding the running web by a brake bar the end of the running web is pressed onto the holding roller by lowering the pressing and deflecting roller and held on by an adhesive tape.
- the first running web is then cut off. After the pressure and deflection roller and the brake bar have returned to their starting position, the new web is pulled off.
- a disadvantage of this known device is the complex and expensive construction of the curved guideway for the holding rollers, which in the initial position of the holding rollers enables simple cutting of the web to be connected.
- the invention is therefore based on the object of providing a device for splicing webs, in particular paper webs for the production of corrugated cardboard, in which the feeding and connecting of the new web to the running web takes place with greater accuracy and a lower error rate.
- the respective holding roller for receiving the start of the new web is transferred to an initial position; there the start of the new web is given in the correct position, held in a first clamping position by the holding roller with leaf springs provided on the clamping bar, trimmed in a predetermined position and provided with an adhesive tape having a predetermined width.
- the web end is then turned back together with the relevant holding roller into a pressure position, the web being held and guided continuously by the clamping bar or the leaf springs during the turning back.
- the roller is designed so that the coefficient of friction between the roller and the web is greater than between the web and the leaf springs, so that the web is carried by the holding roller during the return movement. After transfer to the working position, a correct assignment to the running web can be achieved, so that splicing of the web with a remaining flag is avoided.
- the device 1 for splicing paper webs comprises a web unwinder 2, the splicing device 3 and a web store 4.
- the conventional web dispenser 2 has a stand 6 which can be fastened to the floor 5 and has lateral support arms 7, 8 for the web rolls 9, 10.
- the web 11 runs from the right web roll 9. From the web roll 10 comes the new web 12, which is to be connected with the beginning of the web to the running web 11 when this web 11 comes to an end.
- a splicing device 4 with at least one web loop 13 is assigned to the splicing device 3.
- the running web 11 runs from the splicing device 3 to a deflection roller 14 which is carried by a carriage, not shown. This can be moved from the starting position shown in FIG. 1 at the right end of the cheeks 15 carried by the stand 6 into the dot-dash position at the left end of the cheeks 15 against a controllable force.
- the running web 11 then passes at the left end of the cheeks 15 via the exit roller 16 in the direction indicated by the arrow out. From there it arrives at a processing station, not shown, e.g. B. to a single-sided corrugated cardboard machine.
- the stock of running web 11 formed by the storage loop 13 is dimensioned such that the operation of the subsequent work station can continue to be operated at an undiminished operating speed during the splicing process.
- two pressure and deflection rollers 17, 18 arranged side by side are arranged off-center, offset towards the exit roller 16.
- the running web 11 runs over a deflection roller 19 pivotably arranged at the right end of the cheeks 15 to the pressure and deflection roller 17 and from there to the storage roller 14 and finally to the exit roller 16.
- the two pressure and deflection rollers 17, 18 are pivotable to a limited extent.
- your central axes are mounted on side angle levers 20.
- These angle levers 20 are pivotable about their pivot axes 21.
- the free ends of the angle levers 20 are connected to piston rods 22 of a pneumatic drive cylinder 23.
- FIG. 1 In the position shown in FIG. 1 there is a holding roller 25 below the pressing and deflecting roller 17.
- This holding roller 25 is rotatably mounted in a carriage 26 according to FIG. 3, which by means of rollers 27 along a straight, horizontal path 28 via a form-fitting Trolley drive can be moved from the illustrated working position into an external, dash-dotted starting position.
- the carriage 26 for the holding roller 25 has an external, bent sheet metal plate 30 according to FIG. 4.
- the new web 12 is started from below via the holding roller 25 and then pulled over the adjoining sheet metal plate 30.
- the protruding end part of the new web 12 is cut off by hand with a knife 31 or mechanically flush with the end of the sheet metal plate 30.
- a double-sided adhesive tape 33 is applied over the length b of the bent leg 32 to the beginning of the new web 12.
- the holding roller 25 is provided on the circumference with a rubber 34 with a high coefficient of friction.
- locking notches 35 are arranged on the holding roller 25 at their ends at a distance of 120 °.
- detent rollers 36 of a detent lever 37 fixedly mounted on the cheeks 15 can engage with an adjustment stop 38.
- the holding roller 25 is assigned a clamping bar 40.
- This clamping bar 40 has a substantially rectangular cross section with protruding shoulders 41 formed on the upper longitudinal edges.
- the upper side 42 runs horizontally and is flat.
- the side walls 44 and the end faces 50 on the shoulders 41 are provided with an elastic friction lining 43.
- the elastic friction linings 43 on the side walls 44 are covered by spaced steel leaf springs 45.
- the holding roller 25 can now be rotated clockwise by 120 ° by a drive motor or by hand, as a result of which the end edge of the start of the new web 12 comes at a distance b from the end face 50 of the shoulder 41 (cf. FIG. 5).
- the beginning of the web 12 on the holding roller 25 remains unchanged because the coefficient of friction of the rubber 34 of the holding roller 25 is greater than that of the leaf springs 45.
- the deflecting roller 52 is previously brought into its lowered position.
- the pressure and deflection roller 17 is further assigned a height-adjustable brake beam 55.
- the brake beam 55 is pivotally mounted via pivot lever 56.
- the underside of the brake beam 55 is provided with an elastic brake pad 57.
- the brake lining 57 of the brake beam 55 interacts with the running web 11 and presses it against the top 42 of the clamping beam 40. As a result, the running web 11 is stopped.
- the pressure and deflection roller 18 is also assigned a brake beam 60 with pivot levers 61 and brake pad 62.
- This brake beam 60 interacts with the holding roller 70 when it is in the working position under the pressure and deflection roller 18. This is the case if, as can be seen from FIG. 2, the running web 11 comes from the left roll 10 and the new web 12 to be connected comes from the right roll 9.
- Each pressure and deflection roller 17, 18 is also assigned a butt knife 64, 65, which is arranged obliquely and cuts into the gusset space 66, between the rollers 17, 25 and 18, 70, respectively.
- Each impact knife 64, 65 is driven to be displaceable in the direction indicated by the arrow. It serves to cut off the running web 11, the flag portion remaining between the roller 17 or 18 and the knife cut corresponding to the length b of the adhesive tape at the beginning of the new web 12.
- FIG. 1 In addition to the holding roller 25, there is still another holding roller 70 shown in FIG. 1 in the outer position, which in the same way serves to receive and hold the start of the new web 12 when it comes from the roll 9.
- This holding roller 70 is also arranged on a carriage with a pawl like the roller 25 and can also be moved in a driven manner via the web 28.
- the deflecting roller 19, like the deflecting roller 52, is arranged such that it can be swung out.
- the pressed-down and deflecting roller 17 presses the held down web 11 against the holding roller 25, the impact knife 64 cuts the web 11, then the brake bar 55 pivots up, the clamping bar 40 is released from its latched position, but remains in approximate position to the holding roller 25, the rollers 17 and 25 move in a pressed position through the web tension, finally the roller 17 pivoted up.
- the splicing according to FIG. 2 is also carried out in the same way.

Description
Die Erfindung betrifft eine Vorrichtung zum Spleißen von Bahnen, insbesondere von Papierbahnen für die Herstellung von Wellpappe mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a device for splicing webs, in particular paper webs for the production of corrugated cardboard with the features of the preamble of patent claim 1.
Ein derartige Vorrichtung zum Spleißen von Bahnen ist aus der DE-A-38 16 223 bekannt. Hierbei werden die zu spleißenden Bahnen von zwei, auf einem Wechselständer angeordneten Bahnrollen abgezogen. Die ablaufende Bahn wird dabei um eine höhenbewegliche Anpreß- und Umlenkwalze geführt und läuft über eine Speicherschlaufe zu einer nachfolgenden Arbeitsstation aus. Die anzubindende neue Bahn wird an einer Haltewalze in Ausgangsstellung mit ihrem Anfang befestigt und durch ein Messer beschnitten. Im Zusammenwirken mit einem Klemmbalken wird der Bahnanfang festgehalten und in eine Arbeitsstellung unter einer von zwei Anpreß- und Umlenkwalzen überführt. Nach Festhalten der ablaufenden Bahn durch einen Bremsbalken wird durch Absenken der Anpreß- und Umlenkwalze das Ende der ablaufenden Bahn auf den Anfang der neuen Bahn auf der Haltewalze gepreßt und durch ein Klebeband festgehalten. Hierauf erfolgt das Abschneiden der ersten ablaufenden Bahn. Nach Rückkehr der Anpreß- und Umlenkwalze sowie des Bremsbalkens in ihre Ausgangsstellung wird die neue Bahn abgezogen.Such a device for splicing webs is known from DE-A-38 16 223. Here, the webs to be spliced are drawn off from two web rolls arranged on an interchangeable stand. The running web is guided around a vertically movable pressure and deflection roller and runs out via a storage loop to a subsequent work station. The beginning of the new web to be tied is fastened to a holding roller in the starting position and trimmed by a knife. In cooperation with a clamping bar, the start of the web is held and transferred to a working position under one of two pressure and deflection rollers. After holding the running web by a brake bar, the end of the running web is pressed onto the holding roller by lowering the pressing and deflecting roller and held on by an adhesive tape. The first running web is then cut off. After the pressure and deflection roller and the brake bar have returned to their starting position, the new web is pulled off.
Nachteilig bei dieser bekannten Vorrichtung ist die aufwendige und teuere Konstruktion der gekrümmten Führungsbahn für die Haltewalzen, die in der Ausgangsstellung der Haltewalzen ein einfaches Beschneiden der anzubindenden Bahn ermöglicht.A disadvantage of this known device is the complex and expensive construction of the curved guideway for the holding rollers, which in the initial position of the holding rollers enables simple cutting of the web to be connected.
Hierzu wurde in der FR-A-2 345 378 eine Vorrichtung mit einer horizontal gerade verlaufenden Führungsbahn für die Haltewalzen vorgeschlagen, wobei die leichte Zugänglichkeit der anzubindenden Bahn für ein einfaches Beschneiden des Bahnendes durch ein Rückdrehen der Haltewalze zusammen mit dem Bahnende nach dem Einlegen der Bahn gewährleistet wird. Diese Vorrichtung weist jedoch den Nachteil auf, daß während des Rückdrehens der Haltewalze das Bahnende manuell an der Walzenoberfläche gehalten werden mußte, um das Bahnende zusammen mit der Walze in eine vorbestimmte Anpreßstellung zu überführen. Hierdurch kann durch ein Versetzen der Bahn relativ zur Walze einseitige Spannungen in der Bahn auftreten, die eine erhebliche Störquelle darstellen und zu einem Ein-/Abreißen der Bahn führen können.For this purpose, a device with a was described in FR-A-2 345 378 horizontally straight guide track proposed for the holding rollers, the easy accessibility of the web to be connected is ensured for a simple trimming of the web end by turning back the holding roller together with the web end after inserting the web. However, this device has the disadvantage that during the turning back of the holding roller, the web end had to be held manually on the roller surface in order to bring the web end together with the roller into a predetermined contact position. As a result, by displacing the web relative to the roller, one-sided tensions can occur in the web, which represent a considerable source of interference and can lead to tearing / tearing of the web.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Spleißen von Bahnen, insbesondere von Papierbahnen für die Herstellung von Wellpappe, zu schaffen, bei der das Zuführen und Anbinden der neuen Bahn an die ablaufende Bahn mit höherer Genauigkeit und geringerer Fehlerquote erfolgt.The invention is therefore based on the object of providing a device for splicing webs, in particular paper webs for the production of corrugated cardboard, in which the feeding and connecting of the new web to the running web takes place with greater accuracy and a lower error rate.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Patentanspruchs 1.The invention solves this problem with the features of claim 1.
Die jeweilige Haltewalze zur Aufnahme des Anfangs der neuen Bahn wird in eine Ausgangsstellung überführt; dort wird der Anfang der neuen Bahn lagegerecht aufgegeben, durch die Haltewalze mit am Klemmbalken vorgesehenen Blattfedern in einer ersten Klemmstellung festgehalten, in vorbestimmter Lage beschnitten und mit einem eine vorbestimmte Breite aufweisenden Klebeband versehen. Anschließend wird das Bahnende zusammen mit der betreffenden Haltewalze in eine Anpreßstellung rückgedreht, wobei die Bahn während des Rückdrehens dauernd von dem Klemmbalken bzw. den Blattfedern gehalten und geführt wird. Hierzu ist die Walze so ausgebildet, daß der Reibwert zwischen Walze und Bahn größer ist, als zwischen der Bahn und den Blattfedern, so daß die Bahn bei der Rückdrehbewegung von der Haltewalze mitgenommen wird. Nach Überführung in die Arbeitsstellung ist eine lagegerechte Zuordnung zur ablaufenden Bahn erreichbar, so daß ein Spleißen der Bahn mit einer Restfahne vermieden wird.The respective holding roller for receiving the start of the new web is transferred to an initial position; there the start of the new web is given in the correct position, held in a first clamping position by the holding roller with leaf springs provided on the clamping bar, trimmed in a predetermined position and provided with an adhesive tape having a predetermined width. The web end is then turned back together with the relevant holding roller into a pressure position, the web being held and guided continuously by the clamping bar or the leaf springs during the turning back. For this purpose, the roller is designed so that the coefficient of friction between the roller and the web is greater than between the web and the leaf springs, so that the web is carried by the holding roller during the return movement. After transfer to the working position, a correct assignment to the running web can be achieved, so that splicing of the web with a remaining flag is avoided.

Die Vorrichtung 1 zum Spleißen von Papierbahnen umfaßt einen Bahnabroller 2, die Spleißvorrichtung 3 und einen Bahnspeicher 4.The device 1 for splicing paper webs comprises a
Der übliche Bahnabroller 2 besitzt einen am Boden 5 befestigbaren Ständer 6 mit seitlichen Tragarmen 7, 8 für die Bahnrollen 9, 10. In Fig. 1 läuft von der rechten Bahnrolle 9 die Bahn 11 ab. Von der Bahnrolle 10 kommt die neue Bahn 12, die mit ihrem Bahnanfang an die ablaufende Bahn 11 anzubinden ist, wenn diese Bahn 11 zu Ende geht.The
Da während des Spleißens der beiden Bahnen 11 und 12 die ablaufende Bahn 11 kurzzeitig angehalten wird, ist der Spleißvorrichtung 3 ein Bahnspeicher 4 mit wenigstens einer Bahnschlaufe 13 zugeordnet. Zur Bildung der Bahnschlaufe 13 läuft die ablaufende Bahn 11 von der Spleißvorrichtung 3 zu einer Umlenkwalze 14, die von einem nicht dargestellten Wagen getragen ist. Dieser ist von der in Fig. 1 dargestellten Ausgangslage am rechten Ende der vom Ständer 6 getragenen Wangen 15 in die strichpunktierte Stellung am linken Ende der Wangen 15 entgegen einer steuerbaren Kraft bewegbar. Die ablaufende Bahn 11 tritt dann am linken Ende der Wangen 15 über die Austrittswalze 16 in der angegebenen Pfeilrichtung aus. Von dort gelangt sie zu einer nicht dargestellten Verarbeitungsstation, z. B. zu einer einseitigen Wellpappenmaschine.Since the running
Der von der Speicherschlaufe 13 gebildete Vorrat an ablaufender Bahn 11 ist so bemessen, daß der Betrieb der nachfolgenden Arbeitsstation während des Spleißvorganges mit unverminderter Arbeitsgeschwindigkeit weiterbetrieben werden kann.The stock of running
An den Seitenwangen 15 sind außermittig, zur Austrittswalze 16 hin versetzt, zwei nebeneinander angeordnete Anpreß- und Umlenkwalzen 17, 18 angeordnet. Wie ersichtlich, läuft die ablaufende Bahn 11 über eine am rechten Ende der Wangen 15 schwenkbar angeordnete Umlenkwalze 19 zur Anpreß- und Umlenkwalze 17 und von dort weiter zur Speicherwalze 14 und schließlich zur Austrittswalze 16.On the
Wie aus Fig. 3 ersichtlich, sind die beiden Anpreß- und Umlenkwalzen 17, 18 begrenzt höhenbeweglich schwenkbar. Hierfür sind Ihre Mittelachsen an seitlichen Winkelhebeln 20 gelagert. Diese Winkelhebel 20 sind um ihre Schwenkachsen 21 schwenkbar. Die freien Enden der Winkelhebel 20 sind mit Kolbenstangen 22 eines pneumatischen Antriebszylinders 23 verbunden.As can be seen from Fig. 3, the two pressure and
Bei der in Fig. 1 wiedergegebenen Stellung befindet sich unterhalb der Anpreß- und Umlenkwalze 17 eine Haltewalze 25. Diese Haltewalze 25 ist nach Fig. 3 drehbar in einem Wagen 26 gelagert, der mittels Rollen 27 längs einer geraden, horizontalen Bahn 28 über einen formschlüssigen Wagenantrieb aus der dargestellten Arbeitsstellung in eine außenliegende, strichpunktierte Ausgangsstellung verfahrbar ist.In the position shown in FIG. 1 there is a
Der Wagen 26 für die Haltewalze 25 besitzt nach Fig. 4 eine außenliegende, abgekantete Blechplatte 30. Die neue Bahn 12 wird mit ihrem Anfang von unten über die Haltewalze 25 und dann über die sich daran anschließende Blechplatte 30 gezogen. Das überstehende Endteil der neuen Bahn 12 wird mittels eines Messers 31 von Hand oder maschinell bündig mit dem Ende der Blechplatte 30 abgeschnitten. Über die Länge b des abgekanteten Schenkels 32 wird auf den Anfang der neuen Bahn 12 ein doppelseitiges Klebeband 33 aufgebracht.The
Die Haltewalze 25 ist am Umfang mit einer Gummierung 34 mit hohem Reibwert versehen.The
Über den Umfang verteilt, sind im Abstand von 120° Rastkerben 35 an der Haltewalze 25 an ihren Enden angeordnet. In diese Rastkerben 35 können Rastrollen 36 eines an den Wangen 15 fest gelagerten Rasthebels 37 mit Justieranschlag 38 eingreifen.Distributed over the circumference, locking
In der in Fig. 4 dargestellten Stellung greift die Rastrolle 36 des Rasthebels 37 in die obenliegende Rastkerbe 35 ein.In the position shown in FIG. 4, the
Der Haltewalze 25 ist ein Klemmbalken 40 zugeordnet. Dieser Klemmbalken 40 besitzt einen im wesentlichen rechteckförmigen Querschnitt mit an den oberen Längsrändern ausgebildeten, vorstehenden Schultern 41. Die Oberseite 42 verläuft horizontal und ist eben ausgebildet.The
Die Seitenwände 44 und die Stirnflächen 50 an den Schultern 41 sind mit einem elastischen Reibbelag 43 versehen.The
Die elastischen Reibbeläge 43 an den Seitenwänden 44 sind von beabstandeten Stahlblattfedern 45 überdeckt.The
In der in Fig. 4 dargestellten Ausgangsstellung ist der mit dem Klemmbalken 40 versehene Wagen 46, der über die Rollen 47 von einem Druckluftmotor über die Bahn 28 bewegbar ist, an die Haltewalze 25 derart angenähert, daß die Blattfedern 45 in Berührung mit der Haltewalze 25 leicht eingedrückt sind. Dadurch wird der Anfang der Bahn 12 festgehalten.In the initial position shown in FIG. 4, the
Die Haltewalze 25 kann nun durch einen Antriebsmotor oder von Hand um 120° im Uhrzeigersinn zurückgedreht werden, wodurch die Endkante des Anfangs der neuen Bahn 12 in Abstand b zur Stirnfläche 50 der Schulter 41 gelangt (vgl.
