Abstract

A web of material, for example the packaging of a paper roll, can be wound by introducing its leading edge into an axial slit of a winding core (5) which is mounted in a stationary anchor (8) so as to be rotatable about a winding shaft (10) and by subsequent rotation thereof to form a reel of material. In order to facilitate the removal of the reel of material, the winding core (5) has a plurality of conveyor rollers (19) which are partly mounted in U-profiles (13a) and form groups lying in a line. Conveyor belts (22a,b) run via two of these groups. The conveyor rollers (19) and conveyor belts (22a,b) form the predominant part of the support surface of the reel of material on the winding core (5). The conveyor rollers, lying nearest to the anchor (8), of the last-mentioned groups can be driven via a conveyor shaft (23), a conical gearing (24) and gearwheels (26, 27, 29) and can set the conveyor belts (22a,b) in motion in such a manner that the reel of material connected to them in a frictionally locking manner is conveyed away towards the winding shaft (10), whereas the non-driven conveyor rollers on which said reel also lies co-rotate. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln von biegsamem flächigem Material gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a device for winding flexible flat material according to the preamble of claim 1.

Derartige Vorrichtungen werden beispielsweise zum Aufwickeln von Verpackungsmaterial zur Volumenverkleinerung vor der Entsorgung desselben verwendet, insbesondere von Verpackungen von Papierrollen, wie sie in der Druckindustrie anfallen.Devices of this type are used, for example, for winding up packaging material for volume reduction before disposal thereof, in particular packaging of paper rolls, as are found in the printing industry.

Eine bekannte gattungsgemässe Vorrichtung ist einer Broschüre "Fördertechnik für Papierrollen in der Druckindustrie", Ausgabe 1990 der Von Roll AG, S. 8 zu entnehmen. Der Wickelkern ist als einseitig drehbar gelagerter, antreibbarer Zylinder ausgebildet. Das Verpackungsmaterial wird in einen durchgehenden axialen Schlitz eingelegt und der Wickelkern in Drehung versetzt, sodass das Material auf ihn aufgewickelt wird. Anschliessend wird er manuell in axialer Richtung abgezogen und entsorgt. Unter Umständen kann sich der Materialwickel sehr fest um den Wickelkern legen, sodass das Abziehen Mühe bereitet.A known generic device can be found in a brochure "Conveyor technology for paper rolls in the printing industry", 1990 edition of Von Roll AG, p. 8. The winding core is designed as a drivable cylinder which is rotatably mounted on one side. The packaging material is placed in a continuous axial slot and the winding core is rotated so that the material is wound onto it. It is then manually removed in the axial direction and disposed of. Under certain circumstances, the material wrap can lie very tightly around the winding core, making it difficult to pull off.

Hier soll durch die Erfindung Abhilfe geschaffen werden. Durch die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, wird eine Aufwickelvorrichtung geschaffen, bei der das Abziehen des Materialwickels unabhängig von der Festigkeit desselben immer problemlos möglich ist. Ausserdem kann dieser Schritt ausgehend von der erfindungsgemässen Lösung sehr leicht automatisiert werden, was aus Gründen der Beschleunigung des Ablaufs, der Arbeitsersparnis und auch der Kalkulierbarkeit des Zeitaufwands insbesondere im Hinblick auf das gewöhnlich weitgehend automatisierte Umfeld erwünscht ist.The invention is intended to remedy this. The invention, as characterized in the claims, provides a winding device in which the material roll can always be pulled off without any problems regardless of its strength. This step can also start from the solution according to the invention can be automated very easily, which is desirable in view of the usually largely automated environment, in order to speed up the process, save work and also calculate the time required.

In Fig. 1 ist die prinzipielle Funktionsweise gattungsgemässer Aufwickelvorrichtungen schematisch dargestellt. Ueber eine Zuführung 1, welche etwa aus Paaren von angetriebenen Rollen 2a,b und einer Führungsrolle 3 besteht, wird aufzuwickelndes Material 4 einem Wickelkern 5 zugeführt und durch einen durchgehenden axialen Schlitz 6 in demselben gestossen. Dabei wird, ausgehend vom Signal eines Sensors 7, die Bewegung der Förderrollen 2a,b so gesteuert, dass die Vorderkante der Materialbahn etwa das Ende des Schlitzes 6 erreicht und dann der Wickelkern 5 in Rotation versetzt und das Material 4 auf denselben gewickelt.In Fig. 1, the principle of operation of generic winding devices is shown schematically. Via a feed 1, which consists approximately of pairs of driven rollers 2a, b and a guide roller 3, material 4 to be wound is fed to a winding core 5 and pushed through a continuous axial slot 6 therein. Starting from the signal of a sensor 7, the movement of the conveyor rollers 2a, b is controlled such that the front edge of the material web reaches approximately the end of the slot 6 and then the winding core 5 is set in rotation and the material 4 is wound thereon.

Im einzelnen umfasst die erfindungsgemässe Vorrichtung eine Verankerung 8, welche mit einem Doppel-T-Träger 9 verschraubt ist und den um eine Wickelachse 10 drehbar gelagerten Wickelkern 5. Dieser besteht aus einem Basisteil 11, welcher im wesentlichen eine Gabel bildet mit Fortsätzen 12a,b,c,d sowie an diese anschliessenden U-Profilen 13a,b. Die U-Profile 13a,b sind voneinander abgewandt, d. h. nach aussen offen und beabstandet, sodass sie und die Paare von Fortsätzen 12a,b und 12c,d, an welche jeweils ein U-Profil 13a bzw. 13b anschliesst, zwischen sich den durchgehenden, sich wesentlich in Richtung der Wickelachse 10 erstreckenden Schlitz 6 bilden.In particular, the device according to the invention comprises a Anchoring 8, which is screwed to a double-T support 9 and the winding core 5, which is rotatably mounted about a winding axis 10. This consists of a base part 11, which essentially forms a fork with extensions 12a, b, c, d and to these subsequent U-profiles 13a, b. The U-profiles 13a, b face away from each other, ie open to the outside and spaced apart, so that they and the pairs of extensions 12a, b and 12c, d, to which a U-profile 13a and 13b is connected, between them , Form slot 6 extending substantially in the direction of the winding axis 10.

Der der Verankerung 8 am nächsten liegende Abschnitt des Basisteils 11 ist zylindrisch ausgebildet. Ueber ihn läuft ein Treibriemen 14. An den Basisteil 11 schliesst eine Wickelwelle 15 an, welche in der Verankerung 8 mittels zweier Kugellager 16a,b drehbar gelagert ist.The section of the base part 11 closest to the anchoring 8 is cylindrical. A drive belt 14 runs over it. A winding shaft 15 connects to the base part 11 and is rotatably mounted in the anchoring 8 by means of two ball bearings 16a, b.

Am Doppel-T-Träger 9 ist ein induktiver Sensor 17 zur Detektion einer am Basisteil 11 des Wickelkerns 5 verankerten Lasche 18 verankert.An inductive sensor 17 for detecting a tab 18 anchored to the base part 11 of the winding core 5 is anchored on the double-T support 9.

Am Wickelkern sind mehrer Förderrollen 19 befestigt. Insbesondere tragen die U-Profile 13a,b jeweils mehrere ihre Seitenstege 20 verbindende Achsen 21, an deren jeder zwei nebeneinander angeordnete Förderrollen 19 sitzen, welche besagte Seitenstege 20 jeweils mit einem Teil ihrer Umfangsfläche überragen. Die in den U-Profilen 13a,b montierten Paare von Förderrollen 19 bilden jeweils zwei in einer Linie liegende Gruppen, von denen die im U-Profil 13a angebrachten durch Förderriemen 22a,b verbunden sind, welche jeweils über alle Förderrollen 19 einer Gruppe laufen. In Fig. 2, 3 ist der Wickelkern unterbrochen dargestellt, sodass jeweils pro Gruppe nur zwei Förderrollen 19 dargestellt sind, es können jedoch, je nach Länge des Wickelkerns 5 und den Eigenschaften des Materials 4 auch wesentlich mehr sein. Aussen an den Seitenstegen 20 sind weitere, kleinere Förderrollen 19 angebracht, deren Achsen gegenüber denen der in den U-Profilen 13a,b montierten Förderrollen 19 geneigt sind.Several conveyor rollers 19 are attached to the winding core. In particular, the U-profiles 13a, b each carry a plurality of axles 21 connecting their side webs 20, each of which has two conveyor rollers 19 arranged next to one another, each of which projects over said side webs 20 with part of their circumferential surface. The pairs of conveyor rollers 19 mounted in the U-profiles 13a, b each form two groups lying in a line, of which the ones attached in the U-profile 13a are connected by conveyor belts 22a, b, which each run over all conveyor rollers 19 of a group. 2, 3, the winding core is shown interrupted, so that only two conveyor rollers 19 are shown for each group, but it can, depending on the length of the winding core 5 and the properties of the material 4 can also be significantly more. On the outside of the side webs 20, further, smaller conveyor rollers 19 are attached, the axes of which are inclined relative to those of the conveyor rollers 19 mounted in the U-profiles 13a, b.

Während die Förderrollen 19 sonst einfach drehbar gelagert sind, sind die der Verankerung 8 zunächst liegenden Förderrollen der beiden mittels Förderriemen 22a,b verbundenen Gruppen antreibbar. Und zwar ist durch die Wickelwelle 15 koaxial eine Förderwelle 23 durchgeführt, welche über ein Kegelgetriebe 24 eine Welle 25 antreibt, auf der ein Zahnrad 26 sitzt, das über ein Zahnrad 27 auf einer Zwischenwelle 28 ein drittes, auf der Achse 21 des besagten Paares von Förderrollen 19 befestigtes Zahnrad 29 treibt.While the conveyor rollers 19 are otherwise simply rotatably mounted, the conveyor rollers of the two groups initially connected to the anchoring 8 can be driven by means of conveyor belts 22a, b. Namely, a winding shaft 15 is carried out coaxially through the winding shaft 15, which drives a shaft 25 via a bevel gear 24, on which sits a gearwheel 26 which, via a gearwheel 27, has a third, on the axis 21 of said pair of, on an intermediate shaft 28 Conveyor rollers 19 fixed gear 29 drives.

Im folgenden wird nun die Funktion der beschriebenen Vorrichtung erläutert.The function of the device described will now be explained below.

Wie bereits im Zusammenhang mit Fig. 1 geschildert, wird die Vorderkante einer aus biegsamem flächigem Material 4 bestehenden Materialbahn durch eine Zuführeinrichtung in den Schlitz 6 des Wickelkerns 5 eingeführt. Dabei überwacht der induktive Sensor 17 durch Detektion der Lasche 18, dass sich der Wickelkern 5 in einer Lage befindet, in welcher der Schlitz 6 in der Zuführrichtung liegt. Sobald die Materialbahn in den Schlitz 6 eingeführt ist, wird der Wickelkern 5 über den Treibriemen 14 in Drehung versetzt, sodass sie auf denselben zu einem in Fig. 3 angedeuteten Materialwickel aufgewickelt wird. Die Förderwelle 23 ist während des Wickelvorgangs von der ihr zugeordneten Antriebseinheit (nicht dargestellt) abgekuppelt.As already described in connection with FIG. 1, the front edge of a material web consisting of flexible flat material 4 is introduced into the slot 6 of the winding core 5 through a feed device. The inductive sensor 17 monitors by detecting the tab 18 that the winding core 5 is in a position in which the slot 6 lies in the feed direction. As soon as the material web has been introduced into the slot 6, the winding core 5 is set in rotation via the drive belt 14, so that it is wound onto the same to form a material winding indicated in FIG. 3. The conveyor shaft 23 is uncoupled from the drive unit (not shown) assigned to it during the winding process.

Durch den Sensor 7 wird das Ende der Materialbahn 4 festgestellt, worauf der Wickelvorgang beendet und der Wickelkern 5 blockiert wird. Der Materialwickel liegt dann mehr oder minder fest an der Aussenfläche des Wickelkerns 5 an. Bei hoher Steifigkeit des Materials 4 ist seine Innenfläche annähernd zylindrisch, wie in Fig. 4 angedeutet, bei geringerer Steifigkeit nähert sie sich einem Prisma an, dessen Grundfläche annähernd der konvexen Hülle des Querschnitts des Wickelkerns 5, oder, genauer gesagt, seiner Projektion in Richtung der Wickelachse 10 entspricht.The end of the material web 4 is determined by the sensor 7, whereupon the winding process is ended and the winding core 5 is blocked. The material wrap then lies more or less firmly on the outer surface of the winding core 5. With high rigidity of the material 4, its inner surface is approximately cylindrical, as indicated in Fig. 4, with lower rigidity it approaches a prism, the base of which approximates the convex envelope of the cross section of the winding core 5, or, more precisely, its projection in the direction corresponds to the winding axis 10.

In jedem Fall wird die Auflagefläche, d. h. jener Teil der Aussenfläche des Wickelkerns 5, den der Materialwickel berührt, zu einem guten Teil durch Förderrollen 19 und insbesondere Förderriemen 22a,b gebildet. Wenn der Materialwickel auch auf unbeweglichen Teilen des Wickelkerns 5 aufliegt, so stört das gewöhnlich nicht, entscheidend ist, dass der Reibschluss mit den angetriebenen Förderriemen 22a,b überwiegt. Es hängt natürlich von den Eigenschaften des Materials, insbesondere der schon erwähnten Steifigkeit und der Elastizität ab, wieviele Förderrollen und -riemen nötig sind und wie sie verteilt sein müssen. Bei einem verhältnismässig steifen und unelastischen Material wie Papier genügt die gezeigte Anordnung.In any case, the bearing surface, i.e. H. that part of the outer surface of the winding core 5 which the material roll touches is largely formed by conveyor rollers 19 and in particular conveyor belts 22a, b. If the material roll also rests on immovable parts of the winding core 5, this does not usually bother, it is crucial that the frictional engagement with the driven conveyor belts 22a, b predominates. How many conveyor rollers and belts are necessary and how they must be distributed depends on the properties of the material, in particular the stiffness and elasticity already mentioned. With a relatively rigid and inelastic material such as paper, the arrangement shown is sufficient.

Zum Ausfördern des Materialwickels wird nun die Förderwelle 23 an eine Antriebseinheit angekuppelt und in Drehung versetzt. Ueber das Kegelgetriebe 24 und die Zahnräder 26, 27, 29 wird die Achse 21, auf der die der Verankerung 4 nächstliegenden Förderrollen 19 sitzen, in Rotation versetzt, sodass die Förderriemen 22a,b sich in die in Fig. 3 durch einen Pfeil angedeutete Richtung bewegen. Durch den auf Reibschluss mit den Förderriemen 22a,b, denen er aufliegt, wird nun der Materialwickel in Richtung der Wickelachse 10 ausgefördert, wobei die nicht angetriebenen Förderrollen 19 frei mitlaufen.To remove the material roll, the conveyor shaft 23 is now coupled to a drive unit and set in rotation. Via the bevel gear 24 and the gearwheels 26, 27, 29, the axis 21 on which the conveyor rollers 19 closest to the anchoring 4 are seated is set in rotation, so that the conveyor belts 22a, b move in the direction indicated by an arrow in FIG. 3 move. Due to the frictional connection with the conveyor belts 22a, b, on which it rests, the material roll is now conveyed out in the direction of the winding axis 10, the non-driven conveyor rollers 19 running freely.

Der Materialwickel kann dann von einer Fördereinrichtung aufgenommen werden, in der er etwa zur weiteren Volumenverkleinerung zwischen Rollen zusammengedrückt wird und die ihn zu einem Sammelbehälter transportiert.The material roll can then be picked up by a conveying device in which it is compressed between rollers, for example for further volume reduction, and which transports it to a collecting container.
