Description

Die Erfindung betrifft eine Wickelvorrichtung zum Auf- oder Abwickeln von Streifen beliebiger Breite nach der Gattung des Hauptanspruchs.The invention relates to a winding device for winding or unwinding strips of any width according to the preamble of the main claim.

Streifen oder Bahnen beliebigen Materials, zum Beispiel Kantenumleimer oder Furnierbahnen, werden in Form von Rollen gelagert und transportiert. Üblicherweise ist bei dem Aufwickelvorgang der Streifen zu Rollen der Wickelvorrichtung eine Schneidevorrichtung vorgeschaltet, die breite Materialbahnen in Streifen beliebiger Breite schneidet. Die Wickelvorrichtung nach dem Stand der Technik weist dabei eine Antriebswelle auf, die eine Lagerwelle mit dreigeteilter Umfangsfläche trägt. Auf die dreigeteilte Umfangsfläche werden die Wickelkerne aufgesteckt und bei Drehung der Antriebswelle werden die drei die Umfangsfläche der Lagerwellen bildenden Teile nach außen gedrückt, so daß die Kerne festgehalten werden. Von der Schneidevorrichtung zu der Wickelvorrichtung sind entsprechend dem geschnittenen Streifen Führungen vorgesehen, die die Streifen jeweils zwischen diesen beiden Vorrichtungen führen. Zwischen den Wickelkernen auf der Lagerwelle sind gesonderte Abstandshalter angeordnet. Weisen die aufzuwikkelnden Streifen unterschiedliche Dicken auf oder bestehen sie aus unterschiedlichen Materialien, so kann es vorkommen, daß bei dem Aufwickelvorgang, bei dem die Wickelkerne auf der Lagerwelle bzw. Antriebswelle mit der gleichen Geschwindigkeit umlaufen, einige Streifen durchhängen, während andere Streifen straff gespannt sind. Dadurch entstehen unterschiedliche Wickelhärten der Rollen und trotz der Abstandshalter können Überlappungen der einzelnen Streifen vorkommen. Außerdem ist aufgrund der zwischen den Kernen vorgesehenen Abstandshalter ein größerer Wickelraum ungenutzt.Strips or sheets of any material, such as edge banding or veneer sheets, are stored and transported in the form of rolls. Usually, during the winding process of the strips to rolls of the winding device, a cutting device is connected upstream, which cuts wide material webs into strips of any width. The winding device according to the prior art has a drive shaft which carries a bearing shaft with a three-part circumferential surface. The winding cores are slipped onto the three-part circumferential surface and, when the drive shaft rotates, the three parts forming the circumferential surface of the bearing shafts are pressed outwards, so that the cores are held in place. From the cutting device to the winding device, guides are provided corresponding to the cut strip, which guide the strips between these two devices. Separate spacers are arranged between the winding cores on the bearing shaft. If the strips to be wound have different thicknesses or are made of different materials, it can happen that during the winding process, in which the winding cores on the bearing shaft or drive shaft rotate at the same speed, some strips sag, while other strips are taut . This results in different winding hardnesses of the rolls and, despite the spacers, the individual strips may overlap. In addition, due to the spacers provided between the cores, a larger winding space is not used.

Die EP-A1-0 002 429 zeigt eine bekannte Aufwikkelhaspel zum gleichzeitigen Aufwickeln von wenigstens zwei Bandstreifen, mit einer über eine Welle antreibbaren Wickeltrommel, wobei letztere aus einzelnen jeweils für sich gegenüber der Wickelwelle drehbar gelagerten, über eine Rutschkupplung mit der Welle antriebsverbundenen Trommelringen für die einzelnen Bandstreifen besteht. Über den Wellenumfang und die Trommellänge sind in geeigneter Verteilung radial verschiebbare Druckstössel vorgesehen, die gegen den Innenmantel eines Trommelringes drücken. Damit soll für ein gutes Wickelergebnis ein konstanter Bandzug erreicht werden. Die für das Wickeln notwendigen konstanten Zugspannungen werden durch einen eigenen Bremsmechanismus für die Bandstreifen aufgebracht.EP-A1-0 002 429 shows a known winding reel for the simultaneous winding of at least two strip strips, with a winding drum which can be driven via a shaft, the latter consisting of individual drum rings which are each rotatably mounted relative to the winding shaft and are connected to the shaft via a slip clutch the individual tape strips exist. In a suitable distribution, radially displaceable pressure rams are provided over the shaft circumference and the drum length, which press against the inner jacket of a drum ring. This is to achieve a constant strip tension for a good winding result. The constant tensile stresses required for winding are applied by a separate braking mechanism for the tape strips.

Des weiteren ist in der US-A-4 431 142 gleichfalls eine Aufwickelvorrichtung beschrieben, bei der jedoch zusätzlich angetriebene Umlenkwalzen erforderlich sind sowie weitere zusätzliche Stützwalzen. Auch müssen hier die Wickeldorne aus den Rollen herausgezogen werden, was aufwendig und umständlich ist. Das verwendete Spannelement ist ein drehrichtungsabhängiges, formschlüssig wirkendes Spannelement, welches die Haltekräfte über zwei Punkte in die Hülse einleitet. Hierdurch sind Funktionsstörungen nicht vermeidbar, da die Anfälligkeit der Maschine sich vergrößert.Furthermore, a winding device is also described in US-A-4,431,142, in which, however, additionally driven deflection rollers are required as well as further additional backup rollers. The winding mandrels also have to be pulled out of the rolls here, which is complex and cumbersome. The clamping element used is a rotationally dependent, form-locking clamping element, which introduces the holding forces into the sleeve via two points. This means that malfunctions cannot be avoided because the susceptibility of the machine increases.

Schließlich ist noch eine Vorrichtung an Maschinen zum Aufwickeln von Bahnen bekannt, (DE-A-2 449 724) bei der auf einer Mitnehmerweller Mitnehmerringe nebeneinander axial verschiebbar angeordnet und drehbar gelagert sind. Zwischen den Mitnehmerringen liegen flanschartige Friktionsringe, welche ebenfalls axial verschiebbar, jedoch gegenüber der Welle unverstellbar angeordnet sind. Der letzte Ring, am Ende der Welle, stützt sich gegen eine Schulter ab, während der Endring auf der entfernt liegenden anderen Seite federkraftbeaufschlagt ist.Finally, a device on machines for winding webs is known (DE-A-2 449 724) in which driver rings are arranged axially displaceably next to one another and rotatably mounted on a driver shaft. Flange-like friction rings are located between the driver rings, which are also axially displaceable, but are arranged so that they cannot be adjusted with respect to the shaft. The last ring, at the end of the shaft, is supported against a shoulder, while the end ring on the other side, which is distant, is spring-loaded.

Von diesem Stand der Technik ausgehend setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, eine verbesserte Wickelvorrichtung zum Auf- oder Abwickeln von Streifen beliebiger Breite zu schaffen, die derart ausgebildet ist, daß die Streifen möglichst störunanfällig mit konstanter Wickelhärte bei einfachem Vorrichtungsaufbau aufgewickelt und bei konstanter Zuggeschwindigkeit abgewickelt werden können, wobei der zur Verfügung stehende Wickelraum vollausnutzbar sein soll.Starting from this prior art, the present invention, which is based on the object of providing an improved winding device for winding or unwinding strips of any width, which is designed such that the strips are wound as unaffected by faults as possible with constant winding hardness with a simple device structure and can be handled at a constant train speed, whereby the available changing space should be fully usable.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst.This object is achieved by the characterizing features of the main claim in connection with the features of the preamble.

Bei der vorliegenden Erfindung bilden die Friktionsringe bzw. Friktionsscheiben gleichzeitig den Aufnahmeträger für den Wickelkern, das heißt die Friktionsscheibe ist eine Einheit und führt die unterschiedlichen Funktionen des Aufbringens eines radialen Druckes und der Aufnahme der Wickelkerne aus. Dazu ist in vorteilhafter Weise eine fest mit der Antriebsachse verbundene Buchse mit Flansch vorgesehen, auf der gleitend ein Spannring sitzt, wobei der Flansch gegen eine Stirnfläche des Spannringes drückt und den gewünschten axialen Druck aufbringt. Auf den Spannring ist zusätzlich der aus drei Segmenten bestehende Mitnehmerring derart angeordnet, daß er sich leicht von der Umfangsfläche des Spannringes abheben kann und die Wickelkerne festspannt.In the present invention, the friction rings or friction disks at the same time form the receiving carrier for the winding core, that is to say the friction disc is a unit and carries out the different functions of applying a radial pressure and receiving the winding cores. For this purpose, a bushing with a flange which is fixedly connected to the drive axle is advantageously provided, on which a tensioning ring slides, the flange pressing against an end face of the tensioning ring and applying the desired axial pressure. The driver ring consisting of three segments is additionally arranged on the tension ring in such a way that it can easily stand out from the circumferential surface of the tension ring and clamps the winding cores.

Im Gegensatz zum Stand der Technik ist die Anordnung der Friktionsscheiben gemäß der Erfindung unabhängig von der Breite der Wickelkerne und es müssen nicht Veränderungen hinsichtlich der Trägerelemente oder Friktionselemente oder bestimmter Abstandsstücke vorgenommen werden.In contrast to the prior art, the arrangement of the friction disks according to the invention is independent of the width of the winding cores and there is no need to make changes with regard to the carrier elements or friction elements or certain spacers.

Durch Vorsehen von besonders ausgebildeten Friktionsscheiben, die in einer Vielzahl in Hintereinanderordnung auf der Antriebswelle der Wickelvorrichtung druckbeaufschlagt festgeklemmt sind, ist die Wickelhärte unabhängig vom momentanen Durchmesser der Streifenrolle, von der Dicke und Härte bzw. der Flexibilität des aufzuwickelnden Materials und von der Streifenbreite, wobei außerdem die Wickelhärte durch den Friktionsandruck vorgebbar ist.By providing specially designed friction disks, which are clamped in a plurality in succession on the drive shaft of the winding device, the winding hardness is independent of the current diameter of the strip roll, the thickness and hardness or the flexibility of the material to be wound up and the strip width, whereby in addition, the winding hardness can be predetermined by the friction pressure.

Weiterhin besteht ein großer Vorteil der Erfindung darin, daß zum Bestücken oder Entnehmen der Wickelkerne keine zusätzliche Vorrichtung nötig ist und die Wickelachsen nicht aus der Maschine genommen werden müssen. Die Wikkelkerne können leicht und ohne Vorrichtung von Hand auf die Aufnahmen oder Mitnehmerringe aufgesetzt und abgenommen werden. Die Mitnehmerringe für die Wickelkerne sind selbstspannend, das heißt die letzteren müssen nicht durch eine Handhabe oder zusätzliche Maßnahme gespannt und gegen Lösen gesichert sein.A further advantage of the invention is that no additional device is required for loading or unloading the winding cores and that the winding axes do not have to be removed from the machine. The winding cores can be easily placed and removed by hand on the receptacles or drive rings without any device. The driver rings for the winding cores are self-tightening, which means that the latter do not have to be tensioned by a handle or additional measures and secured against loosening.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail in the following description.

Es zeigen:

  • Fig. 1 eine Aufsicht auf die Friktionsscheibe; und
  • Fig. 2 einen Schnitt durch die auf der Antriebswelle angeordnete Friktionsscheibe.
Show it:
  • Figure 1 is a plan view of the friction disc. and
  • Fig. 2 shows a section through the friction disc arranged on the drive shaft.

Die Friktionsscheibe gemäß Fig. 1 besteht aus mehreren Teilen: einer Buchse 2, einem Spannring 3 und einem aus drei Segmenten 4, 5, 6 bestehenden Mitnehmerring 7. Entsprechend Fig. 2 ist die Buchse 2 mit einer Antriebsachse 8 über einen Teil 9 formschlüssig verbunden und besteht aus einem zylinderförmigen Ansatz 10 und einem Flansch 11. Für die Buchse kann als Material vorzugsweise Stahl gewählt werden.1 consists of several parts: a bushing 2, a clamping ring 3 and a driving ring 7 consisting of three segments 4, 5, 6. According to FIG. 2, the bushing 2 is positively connected to a drive shaft 8 via a part 9 and consists of a cylindrical extension 10 and a flange 11. Steel can preferably be selected as the material for the bushing.

Auf dem zylinderförmigen Ansatz 10 sitzt in Spielpassung der Spannring 3, der in einer Stirnfläche eine ringförmige Vertiefung 12 aufweist. Die Buchse 2 liegt mit ihrem Flansch 11 in dieser Vertiefung 12, wobei die Stirnfläche des Flansches 11 etwas über die äußere Stirnfläche des Spannringes 3 hinausragt. Der Spannring 3 ist auf seiner Umfangsfläche mittig mit einem schlitzartigen Einschnitt 13 versehen und besitzt außerdem drei durch die Stirnflächen hindurchgehende langgestreckte Durchbrechungen 14. Auf der Umfangsfläche des Spannringes 3 ist der im Querschnitt T-förmige Mitnehmerring 7 angeordnet, wobei der eine Schenkel des Mitnehmerringes 7 in den Einschnitt 13 eingreift und gleitend darin geführt ist. Die einzelnen Segmente 4, 5, 6 des Mitnehmerringes 7 werden durch in den Durchbrechungen 14 geführte Stifte 15 gehalten. Die langgestreckten Durchbrechungen und der durch die Umfangsfläche des Spannringes 3 vorgegebene Kreis sind nicht konzentrisch angeordnet, so daß die Segmente 4, 5, 6 bei Verschiebung in den Durchbrechungen 14 sich von der Umfangsfläche des Spannringes 3 abheben. In der inneren Umfangsfläche des Spannringes 3 sind zwei bogenförmige Einschnitte 16, 17 angeordnet.The clamping ring 3, which has an annular recess 12 in an end face, sits on the cylindrical extension 10 in a clearance fit. The socket 2 lies with its flange 11 in this recess 12, the end face of the flange 11 projecting somewhat beyond the outer end face of the clamping ring 3. The clamping ring 3 is provided with a slot-like incision 13 in the center on its peripheral surface and also has three elongated openings 14 passing through the end faces. The driving ring 7 with a T-shaped cross section is arranged on the peripheral surface of the clamping ring 3, one leg of the driving ring 7 engages in the incision 13 and is slidably guided therein. The individual segments 4, 5, 6 of the driving ring 7 are held by pins 15 guided in the openings 14. The elongated openings and the circle predetermined by the peripheral surface of the clamping ring 3 are not arranged concentrically, so that the segments 4, 5, 6 stand out from the peripheral surface of the clamping ring 3 when displaced in the openings 14. Two arcuate incisions 16, 17 are arranged in the inner peripheral surface of the clamping ring 3.

Auf der Umfangsfläche des Mitnehmerringes 7 sitzt der Wickelkern 18, auf den ein Streifen aufgewickelt wird.The winding core 18, on which a strip is wound, is seated on the peripheral surface of the driving ring 7.

Eine Vielzahl von den in Fig. 1 und Fig. 2 dargestellten Friktionsscheiben 1 sind auf der Antriebswelle 8 nebeneinander angeordnet und festgeklemmt. Dabei wird jeweils der Flansch 11 der Buchse 2 einer Friktionsscheibe gegen die Stirnfläche des Spannringes 3 der anderen Friktionsscheibe gedrückt. Die Streifen werden von der Schneidvorrichtung kommend auf die Wickelkerne 18 aufgewickelt, wobei Wickelkern und Streifen mehrere Friktionsscheiben 1 überdecken können. Wird bei dem Aufwickelvorgang die Zugkraft auf den Streifen größer als der Friktionsdruck, so rutschen die dem Streifen zugeordneten Spannringe 3 solange auf den Buchsen 2 durch, bis die Zugkraft wieder geringer wird und Spannring und Buchse miteinander umlaufen. Auf diese Weise sind die auf die einzelnen Kerne aufzuwikkelnden Streifen unabhängig voneinander gespannt und die Parameter eines Streifens wirken sich nicht auf die anderen aus. Somit wird für alle Streifen eine konstante Wickelhärte erreicht, wobei diese Wickelhärte durch Veränderung des Friktionsandruckes unterschiedlich vorgebbar ist. Da die Streifen immer straff gespannt sind, können Abstandshalter und Führungen zwischen Wickelvorrichtung und Schneidvorrichtung entfallen.A large number of the friction disks 1 shown in FIGS. 1 and 2 are arranged side by side on the drive shaft 8 and clamped. In this case, the flange 11 of the bushing 2 of a friction disk is pressed against the end face of the clamping ring 3 of the other friction disk. Coming from the cutting device, the strips are wound onto the winding cores 18, wherein the winding core and strips can cover several friction disks 1. If during the winding-up process the tensile force on the strip is greater than the friction pressure, the clamping rings 3 assigned to the strip slip through on the bushes 2 until the tensile force becomes lower again and the clamping ring and bushing rotate with one another. In this way, the strips to be wound onto the individual cores are stretched independently of one another and the parameters of one strip do not affect the others. A constant winding hardness is thus achieved for all strips, this winding hardness being specifiable differently by changing the friction pressure. Since the strips are always taut, spacers and guides between the winding device and the cutting device can be omitted.

Im vorhergehenden ist die Wickelvorrichtung in der Weise beschrieben worden, daß Streifen aufgewickelt werden. Selbstverständlich kann die Wickelvorrichtung auch zum Abwickeln von Streifen verwendet werden, wobei durch die besondere Ausgestaltung der Friktionsscheiben bzw. durch den Friktionsandruck eine konstante Zuggeschwindigkeit vorgebbar ist.In the foregoing, the winding device has been described in such a way that strips are wound up. Of course, the winding device can also be used for unwinding strips, a constant pulling speed being specifiable by the special design of the friction disks or by the friction pressure.
