Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln von Materialbahnen, bestehend aus mindestens einer Wickeleinrichtung, vorzugsweise aus zwei um 180 Grad zueinander versetzt auf einer zentralen Welle gehalterten Wickeleinrichtungen mit in Trägern, die in ihrem axialen Abstand relativ zueinander verstellbar sind, drehbar gelagerten und miteinander fluchtenden Haltedornen, die zur Aufnahme von zwischen diesen eingespannten Wickelhülsen bestimmt sind wobei je ein Haltedorn jeder Wickeleinrichtung mit einem Antrieb versehen und der jeweils andere frei drehbar auf einem axial verschieblichen Zapfen, vorzugsweise auf der Kolbenstange einer pneumatischen Kolben-Zylinder-Einheit gelagert ist, der zwischen seiner die Wickelhülse einspannenden Spannstellung und seiner zurückgefahrenen Stellung um eine Strecke beweglich ist, die mindestens der Summe der Eintauchtiefen der beiden Haltedorne in die Bohrungen der Wickelhülsen entspricht, und mit einer an die zwischen den Haltedornen gehaltene Wickelhülse anstellbaren Andrückwalze.The invention relates to a device for winding material webs, consisting of at least one winding device, preferably of two winding devices which are offset by 180 degrees from one another on a central shaft, with holding mandrels which are rotatably mounted and aligned with one another in carriers which are adjustable in axial distance relative to one another , which are intended to receive winding sleeves clamped between them, each holding mandrel of each winding device is provided with a drive and the other freely rotatable on an axially displaceable pin, preferably on the piston rod of a pneumatic piston-cylinder unit, which is mounted between its the clamping position clamping the winding sleeve and its retracted position is movable by a distance which corresponds at least to the sum of the immersion depths of the two holding mandrels in the bores of the winding sleeves, and with one held between the holding pins An adjustable pressure roller.

Eine Vorrichtung dieser Art ist aus der US-PS 32 98 624 bekannt. Da die Eintauchtiefen der beiden Haltedorne in die Bohrung der Wickelhülsen verhältnismäßig groß sein müssen, um eine gute Halterung der Wickelhülsen auf den Haltedornen ohne zu Beschädigungen oder Verformungen führende unzulässig hohe Andrückkräfte bzw. Flächendrücke zu gewährleisten, muß die Ausfahrlänge des Zapfens bzw. der Kolbenstagnge aus der diesen halternden Buchse oder dem Zylinder ebenfalls verhältnismäßig groß sein. Wegen des Gewichts der Wickelrolle und insbesondere auch wegen der zusätzlich von der Andrückwalze auf die Wickelrolle übertragenen Andruckkraft wirken auf den in seiner Haltestellung befindlichen Zapfen bzw. die Kolbenstange erhebliche diese auf Biegung beanspruchende Kräfte. Damit der Zapfen oder die Kolbenstange diese Kräfte ohne unzulässige Durchbiegung aufnehmen kann, müssen diese entsprechend dick ausgeführt werden. Ein größerer Durchmesser des Zapfens oder der Kolbenstange bedingt nun aber auch einen entsprechend größeren Durchmesser der Haltebuchse bzw. des Zylinders sowie der diese halternden Trageinrichtungen. Damit sind aber den Durchmessern der auf der Wickelvorrichtung zu bewickelnden Wickelhülsen Grenzen gesetzt. Um auf der Vorrichtung Wickelhülsen unterschiedlicher Längen bewickeln zu können, muß die Länge der Andrückwalze der größten Länge der zu bewickelnden Wickelhülsen entsprechen. Dies bedeutet aber, daß die Andrückwalze die den Zapfen lagernde Buchse oder den Zylinder und deren Halteeinrichtungen überragt, wenn die Träger der Haltedorne zum Bewickeln von kürzeren Wickelhülsen enger zusammengerückt sind, also einen geringeren axialen Abstand voneinander aufweisen. Überdeckt die Andrückwalze aber die den Zapfen oder die Kolbenstange halternden Einrichtungen, lassen sich nur Wickelhülsen wickeln, deren Radius größer ist als der Abstand der Mittellinie des Zapfens oder der Kolbenstange von der Außenkante der diese halternden und tragenden Einrichtungen. Da dieser Abstand jedoch wegen der benötigten Dicke des verschieblichen Zapfens bzw. der Kolbenstange relativ groß ist, können kürzere Wickelhülsen geringeren Durchmessers überhaupt nicht mit der bekannten Vorrichtung bewickelt werden oder nur dann, wenn auch die Andrückwalze ausgetauscht und durch eine kürzere ersetzt wird, die der geringeren Länge der zu bewickelnden Wickelhülse kleineren Durchmessers angepaßt ist.A device of this type is known from US-PS 32 98 624. Since the immersion depths of the two holding mandrels in the bore of the winding sleeves must be relatively large in order to ensure that the winding sleeves are held well on the holding mandrels without causing damage or to guarantee deformation-causing impermissibly high pressing forces or surface pressures, the extension length of the pin or the piston rod from the sleeve or cylinder holding this must also be relatively large. Because of the weight of the winding roller and in particular also because of the pressure force additionally transmitted from the pressure roller to the winding roller, the pin or the piston rod in its holding position act considerably on these bending forces. So that the pin or the piston rod can absorb these forces without undue deflection, they must be made thick enough. A larger diameter of the pin or the piston rod now also requires a correspondingly larger diameter of the holding bush or the cylinder and of the supporting devices holding them. However, this limits the diameters of the winding cores to be wound on the winding device. In order to be able to wind winding cores of different lengths on the device, the length of the pressure roller must correspond to the greatest length of the winding cores to be wound. However, this means that the pressure roller protrudes beyond the bushing which supports the pin or the cylinder and its holding devices if the carriers of the holding mandrels are moved closer together for the winding of shorter winding cores, that is to say they have a smaller axial distance from one another. However, if the pressure roller covers the devices holding the pin or the piston rod, only winding cores can be wound whose radius is greater than the distance of the center line of the pin or the piston rod from the outer edge of the devices holding and supporting them. However, since this distance is relatively large due to the required thickness of the displaceable pin or the piston rod, shorter winding sleeves of smaller diameter cannot be wound with the known device at all or only if the pressure roller is also replaced and replaced by a shorter one, which is the shorter length of the to winding winding sleeve of smaller diameter is adapted.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen mit der sich ohne Austausch der Andrückwalze auch dann Wickelhülsen geringeren Durchmessers mit Materialbahnen bewickeln lassen, wenn die die Wickeldorne tragenden Träger so weit zusammengerückt sind, daß die Andrückwalze die den verschieblichen Zapfen bzw die Kolbenstange halternden Einrichtungen überdeckt.The object of the invention is therefore to provide a device of the type mentioned with which winding sleeves of smaller diameter can also be wound with material webs without exchanging the pressure roller when the carriers carrying the mandrels are moved so far together that the pressure roller moves the movable pin or covers the piston rod holding devices.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß der frei drehbare Haltedorn an einem mit dem verschieblichen Zapfen verbundenen Tragstück in Richtung auf die Andrückwalze versetzt exzentrisch zu dem Zapfen gelagert ist.According to the invention, this object is achieved in a device of the generic type in that the freely rotatable holding mandrel is mounted eccentrically to the pin on a support piece connected to the displaceable pin in the direction of the pressure roller.

Bei der erfindungsgemäßen Vorrichtung ist somit der frei drehbare Haltedorn exzentrisch nach außen versetzt auf dem Zapfen gelagert, so daß der Zapfen selbst in der erforderlichen Dicke ausgeführt werden kann, ohne daß dadurch die Anstellbarkeit der Andrückwalze an Wickelhülsen geringeren Durchmessers beeinträchtigt wird, wenn diese die Halte- und Verschiebeeinrichtungen des Zapfens überdeckt.In the device according to the invention, the freely rotatable holding mandrel is thus mounted eccentrically offset outwards on the pin, so that the pin itself can be made in the required thickness without the adjustability of the pressure roller on winding sleeves of smaller diameter being impaired when it holds the pins - And displacement devices of the pin covered.

Auf der Seite des Trägers mit dem in diesem gelagerten und mit einem Drehantrieb versehenen Haltedorn brauchen keine besonderen Maßnahmen getroffen werden, um die Andrückwalze in der erforderlichen Weise auch an Wickelhülsen geringeren Durchmessers anstellen zu können, weil der den Haltedorn tragende angetriebene Wellenzapfen nicht ausfahrbar ist und daher nur eine kurze Länge aufzuweisen braucht, so daß er mit so geringem Durchmesser ausgeführt werden kann, daß besondere Maßnahmen zur Durchmesserverringerung der Lagereinrichtungen nicht getroffen werden brauchen.On the side of the carrier with the holding mandrel mounted in it and provided with a rotary drive, no special measures need to be taken in order to be able to position the pressure roller in the required manner even on winding cores of smaller diameter, because the driven shaft journal carrying the holding mandrel cannot be extended and therefore only needs to have a short length so that it can be carried out with such a small diameter that special measures for reducing the diameter of the bearing devices need not be taken.

Ein Ausführungbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt

An embodiment of the invention is explained below with reference to the drawing. In this shows
Fig. 1
a longitudinal section through the upper part of the winding device and
Fig. 2
the left upper area of Figure 1 in an enlarged view.

In den Seitenteilen 1 des nicht näher dargestellten Maschinengestells ist eine zentrale Welle 2 in nicht näher dargestellter Weise drehbar gelagert. Auf diese zentrale Welle 2 sind eine kreisrunde Scheibe und ein ringförmiges Gehäuse 4 gegeneinander verstellbar und arretierbar aufgesetzt. In dem ringförmigen Gehäuse 4 ist eine über einen nicht dargestellten Motor antreibbare Riemenscheibe 5 gelagert, auf die ein Ritzel 6 aufgesetzt ist. Dieses Ritzel 6 kämmt mit einem Zwischenrad 7, welches seinerseits in die Verzahnung 8 einer Welle 9 eingreift, die einendig aus dem Gehäuse 4 hervorragt. Auf dieses hervorragende Ende 10 der Welle 9 ist ein Spannkopf 11 fest aufgesetzt, auf den Wickelhülsen 12 mittels Spannelementen 13 festgelegt werden können. Die Funktion der Spannelemente 13 ist bekannt und soll an dieser Stelle nicht näher erläutert werden.In the side parts 1 of the machine frame, not shown, a central shaft 2 is rotatably supported in a manner not shown. On this central shaft 2, a circular disc and an annular housing 4 are mutually adjustable and lockable. In the ring-shaped housing 4, a pulley 5 which can be driven by a motor, not shown, is mounted on which a pinion 6 is placed. This pinion 6 meshes with an intermediate wheel 7, which in turn engages in the toothing 8 of a shaft 9 which projects from the housing 4 at one end. On this outstanding end 10 of the shaft 9, a clamping head 11 is fixed, on which the winding tubes 12 can be fixed by means of clamping elements 13. The function of the tensioning elements 13 is known and will not be explained in more detail here.

Die dem Gehäuse 4 gegenüberliegende kreisrunde Scheibe 3 weist ebenfalls zwei einander diametral gegenüberliegende Wickelstellen auf, von denen eine gezeichnet ist. Aus der Zeichnung ist zu ersehen, daß die Wickelstelle aus einem mit der Scheibe 3 fest verbundenen Zylinder 14 besteht, in welchem ein Kolben 15 gelagert ist. Die diesem Kolben 15 zugehörige Kolbenstange 16 ist hohl ausgebildet. In den Hohlraum 17 dieser Kolbenstange 16 ragt eine Stange 18 hinein, welche mit dem Boden 19 des Zylinders 14 fest verbunden ist. Das in den Hohlraum 17 hineinragende Ende der Stange 18 ist mit einer Anschlagscheibe 20 fest verbunden, an dem sich eine die Stange 18 bereichsweise umgreifende Feder 21 einendig abstützt. Das andere Ende der Feder 21 stützt sich an einem Sprengring 22 ab, der in einer Nut des Kolbens 15 gelagert ist. Die Feder 21 versucht demnach, die Kolbenstange stets einzuziehen. Zum Ausfahren des Kolbens 15 und damit auch der Kolbenstange 16 ist eine Preßluftleitung 23 vorgesehen, die in dem hinteren Ende des Zylinderraums 24 mündet.The circular disk 3 opposite the housing 4 also has two diametrically opposite winding points, one of which is shown. From the drawing it can be seen that the winding point consists of a cylinder 14 fixedly connected to the disc 3, in which a piston 15 is mounted. The piston rod 16 associated with this piston 15 is hollow. A rod 18 protrudes into the cavity 17 of this piston rod 16 and is firmly connected to the bottom 19 of the cylinder 14. That in the cavity 17th protruding end of the rod 18 is fixedly connected to a stop disc 20, on which a spring 21 which surrounds the rod 18 in regions is supported at one end. The other end of the spring 21 is supported on a snap ring 22 which is mounted in a groove in the piston 15. The spring 21 therefore tries to always retract the piston rod. To extend the piston 15 and thus also the piston rod 16, a compressed air line 23 is provided which opens into the rear end of the cylinder space 24.

Insbesondere aus der Figur 2 ist zu erkennen, daß mit dem aus dem Zylinder hervorragenden Ende der Kolbenstange 16 eine Tragplatte 25 fest verbunden ist, an der, nach außen versetzt zur Kolbenstange 16 ein Zapfen 26 befestigt ist. Auf diesem Zapfen lagert frei drehbar ein hohler Aufnahmedorn 27 für die Wickelhülsen 12. Die Kolbenstange 16 weist eine Längsnut 29 auf, in die eine Paßfeder 30 eingreift, welche in der Scheibe 3 gelagert ist. Auf diese Weise wird die Kolbenstange 16 gegen Verdrehung gesichert.It can be seen in particular from FIG. 2 that a support plate 25 is fixedly connected to the end of the piston rod 16 protruding from the cylinder, to which a pin 26 is attached, offset to the outside of the piston rod 16. A hollow mandrel 27 for the winding tubes 12 is freely rotatably supported on this pin. The piston rod 16 has a longitudinal groove 29 into which a feather key 30 engages, which is mounted in the disk 3. In this way, the piston rod 16 is secured against rotation.

Aufgrund der gegenüber der Kolbenstange 16 exzentrisch nach außen versetzten Lagerung des Aufnahmedorns 27 kann unabhängig von der Stellung der Scheibe 3 dieselbe zum ringförmigen Gehäuse 4 stets ein und dieselbe Andrückwalze 28 eingesetzt werden. Die Kolbenstange 16 kann dabei entsprechend der auf sie beim Wickelvorgang und aufgrund der Anpreßkraft der Walze 28 einwirkenden Belastung entsprechend groß ausgebildet sein.Due to the mounting of the holding mandrel 27 eccentrically outwardly relative to the piston rod 16, the same pressure roller 28 can always be used with the annular housing 4, regardless of the position of the disk 3. The piston rod 16 can be designed to be correspondingly large in accordance with the load acting on it during the winding process and due to the contact pressure of the roller 28.

Da der Spannkopf 11, der in dem ringförmigen Gehäuse 4 gelagert ist, keine axiale Bewegung ausführt, braucht dieser nicht exzentrisch gelagert zu sein, da das aus dem Gehäuse 4 hervorragende Wellenende 10 sehr kurz sein kann, so daß selbst bei geringem Durchmesser große Kräfte aufgenommen werden können.Since the clamping head 11, which is mounted in the annular housing 4, does not perform any axial movement, this need not be mounted eccentrically, since the shaft end 10 protruding from the housing 4 can be very short, so that large forces are absorbed even with a small diameter can be.
