During winding of the band roller onto the winding shaft the contact roller is pressed away with increasing diameter of the band roller. Preferred Features: A brake acting on the supporting frame of the contact roller increases the counter force produced during winding by friction of the sliding bearing (26) of the supporting frame of the contact roller.

Description

Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln von dünnem Folienband, insbesondere von Aluminiumband, zu einer oder mehreren Bandrollen auf einer Wickelwelle mit Drehantrieb, mit mindestens einer Kontaktwalze, die beim Wickelvorgang am Umfang der sich bildenden Bandrolle unter Druck anliegt.The invention relates to a winding machine for winding thin film strip, in particular aluminum strip, to one or more tape rolls on a winding shaft with rotary drive, with at least one contact roller, which bears against the circumference of the forming tape roll under pressure during the winding process.

Die Kontaktwalzen von aus der DE 43 00 686 A1 bekannten Wickelmaschinen der gattungsgemäßen Art dienen dazu, beim Auflaufen der Folienbahn auf eine Bandrolle die mitlaufende Luftschicht abzuquetschen, um auf diese Weise das Eindringen von Luft in die Bandrolle weitgehend zu verhindern. Ferner kann durch die Anpresskraft zwischen der Bandrolle und der Kontaktwalze die Wickelhärte der Bandrolle beeinflusst werden. Bei der in der DE 43 00 686 A1 beschriebenen Wickelmaschine ist die Kontaktwalze zum Anstellen gegen die Bandrolle in einem verschiebbaren Schlitten gelagert.The contact rollers of out of the DE 43 00 686 A1 known winding machines of the generic type are used to squeeze the running air layer during emergence of the film web on a roll of tape to largely prevent the ingress of air into the roll of tape in this way. Furthermore, the winding hardness of the tape roll can be influenced by the contact force between the tape roll and the contact roller. When in the DE 43 00 686 A1 described winding machine, the contact roller is mounted for hitching against the tape roll in a sliding carriage.

Die gattungsgemäßen Wickelmaschinen, bei denen die Kontaktwalze während des Wickelvorgangs mit einer federelastischen Anpresskraft dauerhaft gegen den Umfang der Bandrolle angestellt wird, haben den Nachteil, dass aufgrund der Unrundheit der Bandrolle, die auf eine auf der Wickelwelle sitzende Wickelhülse aufgewickelt wird, zu Beginn des Wickelvorgangs eine von der Größe der Unrundheit der Bandrolle abhängige translatorische Bewegung entweder der Kontaktwalze bei ortsfester Lagerung der Bandrolle oder der Bandrolle bei ortfester Lagerung der Kontaktwalze auftritt. Diese translatorischen Bewegungen bewirken eine Längenänderung der aufgewickelten Folienbahn und verursachen eine Änderung der Bahnspannung in der zulaufenden Bahn, die von dem Folienmaterial abhängig sind. Je größer der Elastizitätsmodul des Bahnmaterials in Laufrichtung ist, umso stärker wird die Bahnspannung geändert. Eine periodische translatorische Bewegung der Bandrolle oder der Kontaktwalze führt somit zu einer periodischen Spannungspulsation in der Folienbahn. Die Spannungsspitzen wirken gegen die Laufrichtung der Folienbahn in die Wickelmaschine zurück und beeinflussen den gesamten Bahntransport und die Schneidqualität der in einer Schneidstation vor der Aufwickelvorrichtung längsgeschnittenen Folienbahnen.The generic winding machines in which the contact roller is made permanently against the circumference of the tape roll during the winding process with a resilient contact pressure, have the disadvantage that due to the out-of-roundness of the tape roll, which is wound on a winding tube seated on the winding tube, at the beginning of the winding process a dependent on the size of the out-of-roundness of the tape roll translational movement of either the contact roller in stationary storage of the roll of tape or the roll of tape in Orttfaster storage of the contact roller occurs. These translational movements cause a change in length of the wound film web and cause a change in the web tension in the incoming web, which are dependent on the film material. The greater the modulus of elasticity of the web material in the direction of travel, the more the web tension is changed. A periodic translational movement of the tape roll or the contact roller thus leads to a periodic voltage pulsation in the film web. The stress peaks act against the direction of travel of the film web in the winding machine and affect the entire web transport and the cutting quality of the cut longitudinally in a cutting station in front of the winder film webs.

Eine in der WO 2005/082753 A1 beschriebene Wickelmaschine, die im Hinblick auf eine Verminderung der bei der Wickelmaschine nach der DE 43 00 686 A1 auftretenden Auswirkungen von unrunden Bandrollen auf den Wickelvorgang entwickelt wurde, ist dadurch gekennzeichnet, dass die Kontaktwalze ortsfest gelagert ist und die Bandrolle beim Aufwickeln gegen eine inelastisch wirkende Gegenkraft von der Kontaktwalze wegdrückbar gelagert ist.One in the WO 2005/082753 A1 described winding machine, with respect to a reduction in the winding machine after the DE 43 00 686 A1 occurring effects of non-round tape rolls was developed on the winding process, characterized in that the contact roller is mounted stationary and the tape roll is mounted wegdrückbar during winding against an inelastically acting counterforce of the contact roller.

Gemäß der Beschreibung der aus der WO 2005/082753 A1 bekannten Wickelmaschine wird keine elastische Anpresskraft zwischen der Kontaktwalze und der Bandrolle erzeugt, sondern mit zunehmenden Durchmesser drückt sich die Bandrolle von der Kontaktwalze ab, ohne dass eine Rückstellkraft in Richtung zur Kontaktwalze erzeugt wird. Bei unrunden Bandrollen führt dies dazu, dass die Erhöhungen auf dem Umfang der Bandrolle - also die Umfangsbereiche mit größerem Radius als ihre Nachbarbereiche - den Mittelpunkt der Bandrolle unter Kontakt von der Kontaktwalze wegdrücken, ohne dass die Bandrolle im Bereich der kleinen Radien zur Kontaktwalze zurückgedrückt wird. In den Bereichen mit kleineren Radien wird auf diese Weise der Kontaktdruck reduziert oder er ist nicht vorhanden, so dass weniger hart gewickelt wird und sich etwas mehr Luft zwischen den einzelnen Wickellagen ansammeln kann. Gemäß den Feststellungen in der Beschreibung der WO 2005/082753 A1 führt dies zu eine Vergrößerung der Radien der Bandrolle in diesen Bereichen und somit zu einer Verminderung der Unrundheit der Bandrolle sowie zu einer selbstständigen Reduzierung der Spannungspulsation beziehungsweise Spannungsänderung in der beziehungsweise den Materialbahnen und im Idealfall zu einer völligen Unterdrückung der Spannungspulsation.According to the description of the of WO 2005/082753 A1 known winding machine no elastic contact force between the contact roller and the tape roll is generated, but with increasing diameter, the tape roll is pressed from the contact roller, without a restoring force is generated in the direction of the contact roller. For non-round rolls of tape, this causes the ridges on the circumference of the roll of tape - the larger radius peripheral regions than their neighbors - to push the center of the roll from contact against the contact roll without the roll being pushed back to the contact roll in the area of small radii , In the In this way, the contact pressure is reduced or it is absent, so that less hard winding and a little more air can accumulate between the individual winding layers. According to the findings in the description of the WO 2005/082753 A1 This leads to an increase in the radii of the roll of tape in these areas and thus to a reduction in the out-of-roundness of the roll of tape and to an independent reduction of the voltage pulsation or voltage change in the or the material webs and ideally to a complete suppression of the voltage pulsation.

Die durch die WO 2005/082753 A1 bekannte Wickelmaschine weist folgende Nachteile auf:The by the WO 2005/082753 A1 known winding machine has the following disadvantages:

Beim Wickelvorgang nimmt das Gewicht der Bandrolle laufend zu. Damit erhöhen sich die erforderlichen Massenbeschleunigungskräfte für die Bandrolle, der Stickslipeffekt an der Führung des verschiebbaren Wickelschlittens mit der Bandrolle ändert sich und die Reibungskräfte in der Schlittenführung werden vergrößert. Diese Zusammenhänge führen zu unterschiedlichen Abdrückkräften und damit zu für den Wickelprozess unzulässig hohen Pressungen zwischen der Kontaktwalze und dem beziehungsweise den erhabenen Segmenten auf dem Umfang der Bandrolle sowie zu einer Spannungspulsation in der Materialbahn, so dass eine einwandfreie Aufwicklung der Materialbahn beziehungsweise Materialbahnen zu einer Bandrolle nicht mehr gewährleistet ist.During the winding process, the weight of the tape roll is constantly increasing. This increases the required mass acceleration forces for the roll of tape, the stickslip effect on the guide of the displaceable winding carriage with the roll of tape changes and the frictional forces in the slide guide are increased. These relationships lead to different Abdrückkräften and thus for the winding process inadmissible high pressure between the contact roller and the raised segments on the circumference of the roll and a tension pulsation in the web, so that a proper winding of the web or webs to a roll of tape not more is guaranteed.

Der Erfindung liegt die Aufgabe zugrunde, eine Wickelmaschine der gattungsgemäßen Art derart zu verbessern, dass die negativen Auswirkungen von unrunden Bandrollen auf den Wickelvorgang vermindert werden.The invention has for its object to improve a winding machine of the generic type such that the negative effects of non-round tape rolls are reduced to the winding process.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Wickelmaschine mit den Merkmalen des Patentanspruchs 1.This object is achieved by a winding machine with the features of claim 1.

Die Unteransprüche beinhalten vorteilhafte und zweckmäßige Weiterbildungen der Erfindung.The subclaims contain advantageous and expedient developments of the invention.

Hauptbauteile der Rollenschneid- und Wickelmaschine 1 zum Längsteilen von gewalztem dünnen Folienband 2 aus Metall, insbesondere Aluminiumband, in Bandstreifen beziehungsweise Einzelbänder 3 und Aufwickeln der Einzelbänder zu Bandrollen 4 mit gleicher oder unterschiedlicher Bandbreite sind eine Abwickelstation 5 mit einer motorisch angetriebenen Abwickeltrommel 6 zur Aufnahme eines Bandcoils 7 und einer Ablösewalze 8 zum Lösen des Folienbandes 2 von dem Bandcoil 7, eine in einen Maschinenrahmen 9 eingebaute Einlaufführung 10 für das Folienband 2 mit Bahnführungswalzen 11 zum Überführen des Folienbandes 2 zu einer Schneidstation 12 zum Längsteilen des Folienbandes 2 in Einzelbänder 3, der Schneidstation 12 nachgeordnete Bahnführungswalzen 11 zur Steuerung des Bandlaufs 13 im Wechsel zu zwei Aufwickelstationen 14, 15 mit auf einer angetriebenen Wickelwelle 16 angeordneten, nicht dargestellten Wickelhülsen.Main components of the roll cutting and winding machine 1 for slitting rolled thin foil strip 2 made of metal, in particular aluminum strip, in strip strips or individual bands 3 and winding the individual bands to tape rolls 4 with the same or different bandwidth are an unwinding station 5 with a motor-driven unwinding drum 6 for receiving a Bandcoils 7 and a detaching roller 8 for releasing the film strip 2 of the belt coil 7, a built-in machine frame 9 inlet guide 10 for the film strip 2 with web guide rollers 11 for transferring the film strip 2 to a cutting station 12 for slitting the film strip 2 in individual bands 3, the Cutting station 12 Subordinate web guide rollers 11 for controlling the tape run 13 in alternation to two Aufwickelstationen 14, 15 arranged on a driven winding shaft 16, not shown cores.

Die baugleichen Aufwickelstationen 14, 15 sind mit einem in dem Maschinenrahmen 9 mittels eines Antriebs 17 translatorisch verschiebbaren Wickelschlitten 18 ausgestattet, auf dem ein Traggestell 19 zur Lagerung der Wickelwelle 16 für die Bandrollen 4 sowie ein verschiebbar gelagerter Tragrahmen 20 für eine Kontaktwalze 21 angeordnet sind.The identical Aufwickelstationen 14, 15 are equipped with a in the machine frame 9 by means of a drive 17 translationally movable winding carriage 18 on which a support frame 19 for supporting the winding shaft 16 for the tape rolls 4 and a displaceably mounted support frame 20 are arranged for a contact roller 21.

Beim Aufwickeln der Bandrollen 4 auf die Wickelwelle 16 wird die auf dem Wickelschlitten 18 verschiebbar gelagerte Kontaktwalze 21 mit zunehmendem Durchmesser der Bandrollen 4 von diesen weggedrückt.When winding the tape rolls 4 on the winding shaft 16, the displaceably mounted on the winding carriage 18 contact roller 21 is pushed away with increasing diameter of the tape rolls 4 of these.

In den Maschinenrahmen 9 ist ein Sensor 22 eingebaut zum laufenden Erfassen der Verschiebung der Kontaktwalze 21 beim Wickelvorgang, wobei bei einer Verschiebung der Kontaktwalze 21 der Sensor 22 ein Steuersignal zum Einschalten des Antriebs 17 des Wickelschlittens 18 auslöst und der Wickelschlitten 18 mit der Wickelwelle 16 für die Bandrollen 4 und der Kontaktwalze 21 in Richtung der Wickelwelle 16 bis in die Ausgangsposition der Kontaktwalze 21 mit Bezug auf den Maschinenrahmen 9 vorgefahren wird. Auf diese Weise nimmt die Kontaktwalze 21 beim Wickelvorgang eine nahezu stationäre Position ein und der Bandlauf 23 zwischen der Bahnführungswalze 11 im Maschinenrahmen 9 und der Kontaktwalze 21 erfährt ebenfalls kaum eine Änderung.In the machine frame 9, a sensor 22 is installed for continuously detecting the displacement of the contact roller 21 during the winding process, wherein upon displacement of the contact roller 21, the sensor 22 triggers a control signal for switching on the drive 17 of the winding carriage 18 and the winding carriage 18 with the winding shaft 16 for the tape rollers 4 and the contact roller 21 in the direction of the winding shaft 16 is moved up to the starting position of the contact roller 21 with respect to the machine frame 9. In this way, the contact roller 21 takes a nearly stationary position during the winding process and the tape run 23 between the web guide roller 11 in the machine frame 9 and the contact roller 21 also undergoes hardly any change.

Entsprechend der Darstellung in Figur 2b ist bei Beendigung des Wickelvorgangs die Kontaktwalze 21 auf dem Wickelschlitten 18 ganz nach hinten gefahren und der Wickelschlitten 18 mit den fertig aufgewickelten Bandrollen 4 ist aus dem Maschinenrahmen 9 ausgefahren.As shown in FIG. 2b At the end of the winding process, the contact roller 21 is driven on the winding carriage 18 to the very back and the winding carriage 18 with the finished wound tape rolls 4 is extended from the machine frame 9.

Gemäß der Darstellung in Figur 2c ist das Traggestell 19 zur Lagerung der Wickelwelle 16 für die Bandrollen 4 mit zwei Schwenkarmen 24 mit einem Schwenkantrieb 25 zum Abladen der aufgewickelten Bandrollen 4 ausgestattet.As shown in Figure 2c is the support frame 19 for supporting the winding shaft 16 for the tape rolls 4 with two pivot arms 24 with a pivot drive 25 for unloading the wound tape rolls 4 equipped.

Die Aufwickelstationen 14, 15 können mit einer auf die verschiebbar gelagerten Tragrahmen 20 für die Kontaktwalzen 21 wirkenden mechanischen Bremse zur Erhöhung der durch die Lagerreibung der Verschiebelager 26 der Tragrahmen 20 der Kontaktwalze 21 beim Wickelvorgang erzeugten Gegenkraft ausgestattet werden.The Aufwickelstationen 14, 15 can be equipped with a force acting on the displaceably mounted support frame 20 for the contact rollers 21 mechanical brake to increase generated by the bearing friction of the sliding bearing 26 of the support frame 20 of the contact roller 21 during the winding process counterforce.

Ferner besteht die Möglichkeit, die Wickelstationen 14, 15 mit einem Stellantrieb zum Anstellen der Kontaktwalze 21 gegen den Umfang der Bandrollen 4 insbesondere zu Beginn des Wickelvorgangs auszurüsten.It is also possible, the winding stations 14, 15 equipped with an actuator for hiring the contact roller 21 against the circumference of the tape rolls 4 in particular at the beginning of the winding process.

Bei der erfindungsgemäßen Wickelmaschine wird keine elastische Anpresskraft zwischen der Kontaktwalze und der beziehungsweise den Bandrollen erzeugt, sondern mit zunehmendem Durchmesser drückt sich die Kontaktwalze von den Bandrollen ab, ohne dass eine Rückstellkraft in Richtung zu den Bandrollen erzeugt wird. Bei unrunden Bandrollen führt dies dazu, dass die Erhöhungen auf dem Umfang der Bandrollen, also die Umfangsbereiche mit größerem Radius als ihre Nachbarbereiche den Mittelpunkt der Kontaktwalze unter Kontakt von den Bandrollen wegdrücken, ohne dass die Kontaktwalze im Bereich der kleineren Radien zu den Bandrollen zurückgedrückt wird. In den Bereichen mit kleineren Radien wird so der Kontaktdruck reduziert oder er ist nicht vorhanden, so dass weniger hart gewickelt wird und sich etwas mehr Luft zwischen den einzelnen Wickellagen der Bandrollen ansammeln kann. Dies führt zu einer Vergrößerung der Radien in diesen Bereichen und somit zu einer Verminderung der Unrundheit der Bandrollen und zu einer Reduzierung der Spannungspulsation in den Folienbändern beziehungsweise Folienbahnen.In the winding machine according to the invention no elastic contact force between the contact roller and the or the reels is produced, but with increasing diameter, the contact roller is pressed from the tape rolls without a restoring force is generated in the direction of the tape rolls. In the case of non-round band rolls, this causes the ridges on the circumference of the band rolls, ie the peripheral regions with a larger radius than their neighboring areas, to push the center of the contact roll away from the band rolls under contact, without the contact roll being pushed back to the band rolls in the area of the smaller radii , In the areas with smaller radii so the contact pressure is reduced or it is not present, so that less hard is wound and a little more air can accumulate between the individual winding layers of the tape rolls. This leads to an increase in the radii in these areas and thus to a reduction in the out-of-roundness of the tape rolls and to a reduction in the stress pulsation in the film strips or film webs.
