Abstract

Die Erfindung betrifft eine Blaskasten-Verbindungswand. Bei Tragwalzen-Wickelmaschinen mit Blaskästen kommt es von Zeit zu Zeit zum Abriß der Papierbahn. Die Papierbahn fällt in diesem Fall in den Blaskasten. Dieser Papierabfall muß so schnell wie möglich entfernt werden. Daher weist der erfindungsgemäße Blaskasten eine Verbindungswand zwischen den Seitenwänden auf. Beim Abriß der Papierbahn fällt der Papierabfall dann nicht mehr in den Blaskasten sondern wird von der Verbindungswand aufgefangen, wodurch eine schnelle und einfache Beseitigung des Abfalls ermöglicht wird.

The invention relates to a blow box connecting wall. In the case of carrier roll winding machines with blow boxes, the paper web is torn off from time to time. In this case, the paper web falls into the blow box. This waste paper must be removed as soon as possible. Therefore, the blow box according to the invention has a connecting wall between the side walls. When the paper web is torn off, the paper waste no longer falls into the blow box but is caught by the connecting wall, which enables the waste to be removed quickly and easily.

Description

Die Erfindung betrifft einen Blaskasten gemäß dem Oberbegriff des Anspruches 1.The invention relates to a blow box according to the preamble of claim 1.

Beim Wickeln von Bahnen spielt die Wickelhärte eine Rolle für die anschließende Weiterverarbeitung. Besonders bei Papierbahnen ist es ganz entscheidend, daß die Wickelhärte über den gesamten Rollendurchmesser einen bestimmten Verlauf hat. Im allgemeinen soll die Wickelhärte von einem gewissen Anfangswert auf einen Endwert abfallen. Der Abfall soll von der ersten bis zur letzten Lage möglichst gleichmäßig sein. Er soll einen bestimmten Gradienten aufweisen, d.h., nicht zu stark und nicht zu schwach sein. Der Verlauf der Wickelhärte soll auf gar keinen Fall Sprungstellen aufweisen, z.B. einen plötzlichen Abfall.When winding webs, the winding hardness plays a role for the subsequent processing. With paper webs in particular, it is very important that the winding hardness has a certain course over the entire roll diameter. In general, the winding hardness should drop from a certain initial value to an end value. The waste should be as even as possible from the first to the last layer. It should have a certain gradient, i.e. not too strong and not too weak. The course of the winding hardness should under no circumstances have jump points, e.g. a sudden drop.

Man erreicht dies nur, wenn man bestimmte Maßnahmen ergreift. Unternimmt man nichts, so wird mit zunehmendem Rollendurchmesser der Liniendruck zwischen der Rolle und der Tragwalze bzw. den Tragwalzen immer größer, und damit auch die Wickelhärte.This can only be achieved by taking certain measures. If you do nothing, the line pressure between the roller and the support roller or the support rollers increases with increasing roller diameter, and with it the winding hardness.

Um dies zu vermeiden, wendet man bei Wickelvorrichtungen Druckluft an, die durch den Druckluftanschluß in die druckdichte Kammer unter dem Papierwickel eintritt. Dabei können Luftmenge oder Luftdruck entsprechend dem wachsenden Gewicht des Wickels gesteuert werden. Auch ist es möglich, die Kammer über ihre Länge hinweg - d.h. über die Bahnbreite - in Einzelkammern zu sektionieren, und diese Einzelkammern jeweils mit einem Druckanschluß zu versehen. Auf diese Weise läßt sich auch die Durchbiegung des Wickels ausgleichen.To avoid this, compressed air is used in winding devices, which enters through the compressed air connection into the pressure-tight chamber under the paper winding. Air volume or air pressure can be controlled according to the growing weight of the reel. It is also possible to section the chamber over its length - ie across the web width - into individual chambers, and to provide each of these individual chambers with a pressure connection. In this way, the deflection of the winding can also be compensated for.

Aus der EP 91914763 ist eine Wickelvorrichtung bekannt, die einen Blaskasten aufweist, der durch Verschwenken oder Verfahren aus seiner Arbeitsposition entfernbar ist.A winding device is known from EP 91914763, which has a blow box which can be removed from its working position by pivoting or moving.

Ein Nachteil dieser Vorrichtung besteht in folgendem:A disadvantage of this device is as follows:

Bei Tragwalzen-Wickelmaschinen kommt es von Zeit zu Zeit zu Abrissen der Papierbahn. Die Papierbahn fällt in diesem Falle in den Blaskasten; dieser Papierabfall muß so schnell wie möglich entfernt werden. Hierzu muß gemäß der EP 91914763 der gesamte Blaskasten verschwenkt werden.With carrier roller winding machines, the paper web is torn off from time to time. In this case, the paper web falls into the blow box; this waste paper must be removed as soon as possible. For this purpose, the entire blow box must be pivoted according to EP 91914763.

Der Blaskasten hat aber ein ganz erhebliches Bauvolumen sowie ein entsprechend hohes Gewicht. Man muß sich dabei vorstellen, daß er sich über die gesamte Länge des Wickelbettes hinweg erstreckt, die mehrere Meter messen kann, und daß sein Gewicht viele hundert Kilogramm beträgt. Hierzu bedarf es eines aufwendigen Bewegungsmechanismus mit einem entsprechenden Antrieb. Außerdem beansprucht das Verfahren oder Verschwenken des Blaskastens einen ganz erheblichen Bauraum, der häufig nicht zur Verfügung steht.However, the blow box has a very large construction volume and a correspondingly high weight. One has to imagine that it extends over the entire length of the changing bed, which can measure several meters, and that its weight is many hundreds of kilograms. This requires a complex movement mechanism with an appropriate drive. In addition, the process or pivoting of the blow box takes up a very considerable amount of space, which is often not available.

Der Erfindung liegt die Aufgabe zugrunde, einen Blaskasten gemäß dem Oberbegriff von Anspruch 1 zu schaffen, der ortsfest bleibt, wenn man Papierreste nach Abreißen der Papierbahn entnehmen möchte. Es soll dadurch ein aufwendiger Bewegungsmechanismus mit zugehörendem Antrieb für diesen Fall vermieden werden und auch ein geringerer Bauraum für die gesamte Maschine erreicht werden.The invention has for its object to provide a blow box according to the preamble of claim 1, which remains stationary when you want to remove paper residue after tearing off the paper web. This is to avoid a complex movement mechanism with associated drive for this case and also to achieve a smaller installation space for the entire machine.

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

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles beschrieben werden. In Fig. 1 ist ein Blaskasten 1 einer Wickeleinrichtung mit zwei Seitenwänden 1.1 und 1.2 gezeigt, die in einer bevorzugten Ausführungsform feststehend ausgebildet sein können.The invention will be described below using an exemplary embodiment. In Fig. 1, a blow box 1 of a winding device with two side walls 1.1 and 1.2 is shown, which in one preferred embodiment can be designed to be stationary.

Oberhalb des Blaskastens 1 sind zwei Tragwalzen 2, 3, die miteinander ein Wickelbett zur Aufnahme einer darüber liegenden Papierrolle bilden, angeordnet. Die Papierrolle entsteht durch Aufwickeln einer Papierbahn 5. Wie man sieht, wird die Papierbahn 5 von links unten herangeführt und umschlingt die Tragwalze 2. Die Papierrolle kann von einer Belastungs- oder Reiterwalze in steuerbarer Weise belastet sein, um damit auch den Auflagendruck zu beinflussen.Above the blow box 1, two support rollers 2, 3, which together form a winding bed for receiving an overlying paper roll, are arranged. The paper roll is created by winding up a paper web 5. As can be seen, the paper web 5 is brought in from the bottom left and wraps around the support roller 2. The paper roll can be loaded in a controllable manner by a loading or rider roller in order to influence the print run.

Der Blaskasten 1 weist Dichtelemente 7, 8 auf, die eine Abdichtung zwischen den betreffenden Wänden des Blaskastens 1 und der jeweiligen Tragwalze 2 bzw. 3 herstellen.The blow box 1 has sealing elements 7, 8 which produce a seal between the relevant walls of the blow box 1 and the respective support roller 2 or 3.

Im Blaskasten selbst ist das erfindungsgemäße Verbindungselement 10 zwischen den Seitenwänden 1.1 und 1.2 angeordnet.In the blow box itself, the connecting element 10 according to the invention is arranged between the side walls 1.1 and 1.2.

Kommt es zum Abriß der Papierbahn beim Aufwicklen, so fällt die Papierbahn in den Blaskasten. Dieser Papierabfall muß nun so schnell wie möglich entfernt werden. Die Verbindungswand 10 dient dazu, solchen Papierabfall aufzufangen. Liegt der Papierabfall auf der Verbindungswand 10, so läßt er sich viel leichter und schneller durch eine der beiden Stirnseiten des Blaskastens 1 entfernen, als wenn er auf dem Boden des Blaskastens 1 liegen würde. Das Herausschaffen des Papierabfalles kann auch automatisiert werden, beispielsweise mittels eines Kratzers oder eines umlaufenden Förderbandes.If the paper web is torn off during winding, the paper web falls into the blow box. This waste paper must now be removed as quickly as possible. The connecting wall 10 serves to collect such paper waste. If the paper waste lies on the connecting wall 10, it can be removed much more easily and quickly through one of the two end faces of the blow box 1 than if it were lying on the bottom of the blow box 1. The removal of the paper waste can also be automated, for example by means of a scratch or a rotating conveyor belt.

Die Verbindungswand 10 hat im vorliegenden Falle des weiteren noch folgende Funktionen zu erfüllen:In the present case, the connecting wall 10 also has to perform the following functions:

Sie dient der Versteifung des Blaskastens 6 und dazu, die Druckluft, die an einer oder an beiden Stirnseiten dem Blaskasten 1 zugeführt wird (siehe Zuleitung 1.3) über den Querschnitt des Blaskastens 1 hinweg gleichmäßig zu verteilen. Hierzu weist die Verbindungswand 10 Perforationen auf.It serves to stiffen the blow box 6 and to distribute the compressed air that is fed to the blow box 1 on one or both ends (see feed line 1.3) evenly over the cross section of the blow box 1. For this purpose, the connecting wall has 10 perforations.

Gemäß einem weiteren Gedanken könnte die genannte Perforation der Verbindungswand nach einem bestimmten Muster verteilt sein. So wäre es denkbar, daß die Größe oder die Anzahl der Bohrungen in der Verbindungswand gegen die Endbereiche hin abnehmen. Dies könnte deshalb sinnvoll sein, weil sich die Papierrolle gerade im mittleren Bereich besonders stark durchbiegt.According to a further idea, said perforation of the connecting wall could be distributed according to a certain pattern. It would be conceivable that the size or the number of bores in the connecting wall decrease towards the end regions. This could be useful because the paper roll bends particularly strongly in the middle area.

Schließlich könnte auch der Verbindungswand 10 eine Jalousie zugeordnet werden, mit der es möglich ist, die einzelnen Druckluftströme, die durch die Bohrungen der Verbindungswand 10 hindurchtreten, in ihrem Durchsatz willkürlich zu verändern.Finally, a blind could also be assigned to the connecting wall 10, with which it is possible to arbitrarily change the throughput of the individual compressed air flows which pass through the bores of the connecting wall 10.

Eine weitere Ausführungsform der Erfindung ist in Figur 2 dargestellt. Man sieht dort wiederum den Blaskasten 1 sowie die beiden Dichtungen 7, 8. In der vorliegenden Ausführungsform weist der Blaskasten 1 gemäß Fig. 2 zusätzlich zur Verbindungswand 10 Versteifungsrippen 11 auf, die die Seitenwand 1.1 mit der Seitenwand 1.2 des Blaskastens verbinden. Um die Luftzufuhrleitung 1.3 des Blaskastens herum sind Bleche 14 angebracht, mit denen die Luftzufuhrleitung 1.3 im Blaskasten befestigt ist.Another embodiment of the invention is shown in FIG. The blow box 1 and the two seals 7, 8 can be seen there again. In the present embodiment, the blow box 1 according to FIG. 2 has, in addition to the connecting wall 10, stiffening ribs 11 which connect the side wall 1.1 to the side wall 1.2 of the blow box. Around the air supply line 1.3 of the blow box, sheets 14 are attached, with which the air supply line 1.3 is fastened in the blow box.

Wie der Blaskasten gemäß Fig. 1 dient die Verbindungswand 10, die perforiert sein kann, in der dargestellten Ausführungsform ebenfalls dazu, bei Abriß der Papierbahn die Papierreste aufzufangen.Like the blow box according to FIG. 1, the connecting wall 10, which can be perforated, also serves in the illustrated embodiment to collect the paper residues when the paper web is torn off.

Die Verbindungswand 10 ist aber zwischen den Seitenwänden 1.1 und 1.2 darüberhinaus derart geneigt angeordnet, daß die Papierreste selbständig im Blaskasten nach unten gleiten können.The connecting wall 10 is, however, also arranged inclined between the side walls 1.1 and 1.2 in such a way that the paper remnants can slide downward in the blow box independently.

Des weiteren weist der Blaskasten 1 in der Ausführungsform gemäß Fig. 2 eine in die Seitenwand 1.1 eingelassene Öffnung 12 auf. Vor der Öffnung 12 ist eine Einrichtung zum Verschließen angeordnet, beispielsweise wie dargestellt eine Klappe 13, die schwenkbar am Hauptteil des Blaskastens 1 gelagert ist - siehe Schwenkachse 13.1. Direkt vor der Öffnung endet die geneigte Verbindungswand 10, die im unteren Abschnitt 1.4 der Seitenwand 1.1 befestigt ist.Furthermore, the blow box 1 in the embodiment according to FIG. 2 has an opening 12 let into the side wall 1.1. A device for closing is arranged in front of the opening 12, for example, as shown, a flap 13 which is pivotally mounted on the main part of the blow box 1 - see pivot axis 13.1. The inclined connecting wall 10, which is fastened in the lower section 1.4 of the side wall 1.1, ends directly in front of the opening.

Reißt nun die Papierbahn 5, so werden die Papierreste von der Verbindungswand aufgefangen, gleiten aufgrund der Neigung der Verbindungswand 10 zur Öffnung 12 und sammeln sich dort an. Die Papierreste können dann nach Öffnen der vor der Öffnung 12 angeordneten Klappe 13 leicht entnommen werden.If the paper web 5 now tears, the paper residues are caught by the connecting wall, slide due to the inclination of the connecting wall 10 to the opening 12 and collect there. The paper remnants can then be easily removed after opening the flap 13 arranged in front of the opening 12.
