Definitions
- the invention relates to a device with the help of which is located on a roll, one-sided self-adhesive material can be unrolled.
- the unwinding of wide rolls of self-adhesive coated materials turns out to be very difficult. It is known to hold such a roll by means of a corresponding device, and to pull the material off the roll with a permanently installed and driven take-off roller. Because the diameter of the roller decreases over time, the distance between the roller and the take-off roller increases continuously. The consequence of this is that constantly changing conditions occur at the point of withdrawal of the material from the roll. The resulting fluctuating tensile stresses in the unwound material complicate the use of the same in subsequent process steps. In order to avoid this disadvantage, the take-off roller can be adjusted with a corresponding control so that the roller and the take-off roller are kept in constant contact. The advantage of the uniform unwinding of the material is offset by the very complex and expensive adjustment mechanism and control.
- the object of the invention was to provide a device which is available at a very simple constructive design an even deduction of one-sided enables self-adhesive finished material from a roll.
- the device for unrolling one-sided roll self-adhesive material made of two brackets, each with a recess have for receiving the role and which are arranged so that they have a Form a guide for the roller in between, and a driven one Take-off roller, which is wrapped with an elastic material and so is arranged that the material with the non-adhesive side of the roll over the Pull-off roller is pulled off, with the role of the guide on the backdrop entire width of the roll is held in direct contact with the take-off roller.
- the recesses in the holders preferably have the shape of an upward open, inclined "U" s, the angle of inclination being between 10 ° and 80 ° can.
- the recesses serve to receive the core tube, on which the self-adhesive coated material is wrapped. If the core tube does not have the side Protruding edge of the roll of material, mandrels are used to hold the roll, which are inserted into the core tube and which extend into the recesses. Due to this type of scenery, the role decreases due to its own weight so far in the brackets until it is firmly on the driven take-off roller, and over the entire width of the roll.
- the use of the elastic material results in a particularly gentle pulling of the material from the roll, because the elastic material is able to compensate for small unevenness on the roll due to the elasticity.
- the elastic material results in an increased coefficient of friction between the material and the take-off roller, so that, in particular, even strongly adhesive materials can be removed on the take-off roller with possibly small wrap angles.
- the elastic material acts comparable to a spring, so that in conjunction with the link guide during the unwinding of the roll over the entire length of the take-off line, conditions are almost constant, especially since during the unwinding process the roll is additionally pulled to the take-off roller by the forces that occur due to the design.
- the use of foam as an elastic material has proven to be particularly advantageous, especially if it is self-adhesive coated in the form of an endless web and is applied in a spiral, gapless winding on the take-off roller.
- the draw-off roller can be driven by means of a conventional electric motor is attached, for example, in the take-off roller. But also a friction drive over straps is possible.
- a switching mechanism which is actuated by pulling on the material is preferably used for switching the drive of the take-off roller. If the material is pulled behind the device, a tension builds up in the material that can be used to trigger a switch, for example in the form of a spring-mounted switching drum over which the material is guided and which is arranged behind the take-off roller. Due to the increasing tension in the material, the spring used for storage is compressed until a position is reached in which a contact is triggered, which in turn is used to switch on the drive of the take-off roller. If, on the other hand, the tension in the material subsides, for example due to a crack, the shift drum is pressed by the relaxing spring beyond the normal position against a second contact, which causes the drive to switch off immediately. Uncontrolled unwinding of the web is almost impossible.
- the take-off roller can also act as a suction roller be trained.
- the vacuum in the take-off roller is selected to ensure a safe removal of the material to ensure from the roll.
- the use of a guide roller between the roller and the take-off roller has proven to be advantageous.
- the guide roller is in direct contact with the roller over the entire width of the roller, the material being drawn off via the guide roller with the non-adhesive side. There is no contact between guide roller and take-off roller or take-off roller and roller. Since the guide roller reduces the take-off angle of the material from the roll, which leads to a further increase in the uniformity of the take-off and, consequently, to a reduction in the load on the material, the diameter of the guide roller is chosen to be as small as possible.
- the guide roller can also be designed as a guide profile instead of a roller.
- the device according to the invention is for unwinding a large number of self-adhesive coated materials.
- this is particularly advantageous Use of the device for unrolling large areas, self-adhesive on one side equipped material that is used to protect surfaces, preferred of surfaces of automobile bodies, very particularly preferably of painted ones Automobile bodies.
- the device is due to the simple structural design in particular wide material webs, the unwinding process by manual pulling on Material to start. Then the material supplied by the device can then can be applied by hand on the desired surfaces. But also the use the device according to the invention in semi-automatic or automatic Application is possible without restriction.
- the material can be processed further behind the device. So is also the combination of the device with a cutting device for production cut pieces not outside the inventive concept.
- the roller (1) with the self-adhesive coated material is between two brackets (2) which are attached to a cross member (3).
- Two mandrels (4) are used to fix the roller (1), which are inserted into the core tube (11) of the roller (1).

Abstract
Description
Die Erfindung betrifft eine Vorrichtung, mit Hilfe derer auf einer Rolle befindliches, einseitig selbstklebend ausgerüstetes Material abgerollt werden kann.The invention relates to a device with the help of which is located on a roll, one-sided self-adhesive material can be unrolled.
Insbesondere das Abwickeln von breiten Rollen aus selbstklebend beschichteten Materialien,
beispielsweise von Rollen mit einer Breite von einem Meter, gestaltet sich als
sehr schwierig. Bekannt ist, eine derartige Rolle mittels einer entsprechenden Vorrichtung
zu halten, und das Material von der Rolle mit einer fest installierten und angetriebenen
Abzugswalze abzuziehen. Dadurch, daß der Durchmesser der Rolle im Laufe der
Zeit abnimmt, vergrößert sich kontinuierlich der Abstand zwischen Rolle und Abzugswalze.
Dies hat zur Folge, daß sich am Abzugspunkt des Materials von der Rolle ständig
wechselnde Verhältnisse einstellen. Die daraus resultierenden schwankenden Zugspannungen
im abgewickelten Material erschweren die Verwendung desselben in
nachfolgenden Verfahrensschritten.
Um diesen Nachteil zu vermeiden, kann die Abzugswalze mit einer entsprechenden
Regelung so nachgeführt werden, daß die Rolle und die Abzugswalze in ständigem
Kontakt gehalten werden. Dem Vorteil des gleichmäßigen Abwickelns des Materials
steht aber der sehr aufwendige und teure Verstellmechanismus samt Regelung gegenüber.In particular, the unwinding of wide rolls of self-adhesive coated materials, for example rolls with a width of one meter, turns out to be very difficult. It is known to hold such a roll by means of a corresponding device, and to pull the material off the roll with a permanently installed and driven take-off roller. Because the diameter of the roller decreases over time, the distance between the roller and the take-off roller increases continuously. The consequence of this is that constantly changing conditions occur at the point of withdrawal of the material from the roll. The resulting fluctuating tensile stresses in the unwound material complicate the use of the same in subsequent process steps.
In order to avoid this disadvantage, the take-off roller can be adjusted with a corresponding control so that the roller and the take-off roller are kept in constant contact. The advantage of the uniform unwinding of the material is offset by the very complex and expensive adjustment mechanism and control.
Aufgabe der Erfindung war es, eine Vorrichtung zur Verfügung zu stellen, die bei einer sehr einfachen konstruktiven Gestaltung einen gleichmäßigen Abzug eines einseitig selbstklebend ausgerüsteten Materials von einer Rolle ermöglicht. The object of the invention was to provide a device which is available at a very simple constructive design an even deduction of one-sided enables self-adhesive finished material from a roll.
Gelöst wird diese Aufgabe durch eine Vorrichtung, wie sie in Anspruch 1 dargelegt ist. Weiterbildungen der erfindungsgemäßen Vorrichtung sind dabei Gegenstand der Unteransprüche.This object is achieved by a device as set out in claim 1. Developments of the device according to the invention are the subject of the dependent claims.
Demgemäß besteht die Vorrichtung zum Abrollen von auf einer Rolle befindlichem, einseitig selbstklebend ausgerüstetem Material aus zwei Halterungen, die jeweils eine Aussparung zur Aufnahme der Rolle aufweisen und die so angeordnet sind, daß sie eine Kulissenführung für die dazwischen befindliche Rolle bilden, des weiteren aus einer angetriebenen Abzugswalze, die mit einem elastischen Material umwickelt ist und die so angeordnet ist, daß das Material mit der nichtklebenden Seite von der Rolle über die Abzugswalze abgezogen wird, wobei durch die Kulissenführung die Rolle über die gesamte Breite der Rolle in direktem Kontakt mit der Abzugswalze gehalten ist.Accordingly, the device for unrolling one-sided roll self-adhesive material made of two brackets, each with a recess have for receiving the role and which are arranged so that they have a Form a guide for the roller in between, and a driven one Take-off roller, which is wrapped with an elastic material and so is arranged that the material with the non-adhesive side of the roll over the Pull-off roller is pulled off, with the role of the guide on the backdrop entire width of the roll is held in direct contact with the take-off roller.
Die Ausnehmungen der Halterungen weisen vorzugsweise die Form eines nach oben offenen, geneigten "U"'s auf, wobei der Neigungswinkel zwischen 10° und 80° liegen kann. Die Ausnehmungen dienen zur Aufnahme des Kernrohres, auf das das selbstklebend beschichtete Material gewickelt ist. Wenn das Kernrohr nicht über die seitliche Kante der Materialrolle hinausragt, werden zur Aufnahme der Rolle Dorne verwendet, die in das Kernrohr eingeschoben werden und die bis in die Ausnehmungen reichen. Bedingt durch diese Art der Kulissenführung sinkt die Rolle durch ihr eigenes Gewicht soweit in den Halterungen ab, bis sie fest an der angetriebenen Abzugswalze liegt, und zwar über die gesamte Breite der Rolle.The recesses in the holders preferably have the shape of an upward open, inclined "U" s, the angle of inclination being between 10 ° and 80 ° can. The recesses serve to receive the core tube, on which the self-adhesive coated material is wrapped. If the core tube does not have the side Protruding edge of the roll of material, mandrels are used to hold the roll, which are inserted into the core tube and which extend into the recesses. Due to this type of scenery, the role decreases due to its own weight so far in the brackets until it is firmly on the driven take-off roller, and over the entire width of the roll.
Auf der Abzugswalze befindet sich ein elastisches Material. Durch die Verwendung des
elastischen Materials wird zum einen ein besonders schonender Abzug des Materials
von der Rolle erreicht, denn das elastische Material ist aufgrund der Elastizität in der
Lage, kleine Unebenheiten auf der Rolle hervorragend auszugleichen.
Auf der anderen Seite ergibt das elastische Material einen erhöhten Reibungskoeffizienten
zwischen Material und Abzugswalze, so daß insbesondere auch stark klebende
Materialien bei gegebenenfalls kleinen Umschlingungswinkeln auf der Abzugswalze
abgezogen werden können.
Das elastische Material wirkt vergleichbar einer Feder, so daß in Verbindung mit der
Kulissenführung während des Abwickeln der Rolle über die gesamte Länge der Abzugslinie
annähernd konstante Bedingungen herrschen, zumal während des Abwickelvorganges
die Rolle durch die auftretenden Kräfte konstruktionsbedingt zusätzlich an die
Abzugswalze gezogen wird.
Als besonders vorteilhaft hat sich dabei die Verwendung von Schaumstoff als elastisches
Material erwiesen, ganz besonders, wenn dieser selbstklebend beschichtet in
Form einer endlosen Bahn vorliegt und in einer spiralförmigen, lückenlosen Wicklung
auf der Abzugswalze aufgebracht ist.There is an elastic material on the take-off roller. The use of the elastic material results in a particularly gentle pulling of the material from the roll, because the elastic material is able to compensate for small unevenness on the roll due to the elasticity.
On the other hand, the elastic material results in an increased coefficient of friction between the material and the take-off roller, so that, in particular, even strongly adhesive materials can be removed on the take-off roller with possibly small wrap angles.
The elastic material acts comparable to a spring, so that in conjunction with the link guide during the unwinding of the roll over the entire length of the take-off line, conditions are almost constant, especially since during the unwinding process the roll is additionally pulled to the take-off roller by the forces that occur due to the design.
The use of foam as an elastic material has proven to be particularly advantageous, especially if it is self-adhesive coated in the form of an endless web and is applied in a spiral, gapless winding on the take-off roller.
Der Antrieb der Abzugswalze kann mittels eines üblichen Elektromotors erfolgen, der beispielsweise in der Abzugswalze angebracht wird. Aber auch ein friktionaler Antrieb über Riemen ist möglich.The draw-off roller can be driven by means of a conventional electric motor is attached, for example, in the take-off roller. But also a friction drive over straps is possible.
Für die Schaltung des Antriebs der Abzugswalze wird vorzugsweise ein Schaltmechanismus
verwendet, der durch Zug am Material betätigt wird. Wird hinter der Vorrichtung
am Material gezogen, baut sich in dem Material eine Spannung auf, die zum Auslösen
eines Schalters genutzt werden kann, beispielsweise in Form einer federnd gelagerten
Schaltwalze, über die das Material geführt wird, und die hinter der Abzugswalze angeordnet
ist. Durch die anwachsende Spannung in dem Material wird hierbei die zur Lagerung
genutzte Feder zusammengepreßt, bis eine Stellung erreicht ist, in der ein Kontakt
ausgelöst wird, der wiederum zum Anschalten des Antriebs der Abzugswalze genutzt
wird.
Läßt auf der anderen Seite die Spannung in dem Material beispielsweise durch einen
Riß nach, wird die Schaltwalze durch die sich entspannende Feder über die normale
Stellung hinaus gegen einen zweiten Kontakt gedrückt, der das sofortige Abschalten
des Antriebs bewirkt. Ein unkontrolliertes Abwickeln der Bahn ist somit nahezu unmöglich.A switching mechanism which is actuated by pulling on the material is preferably used for switching the drive of the take-off roller. If the material is pulled behind the device, a tension builds up in the material that can be used to trigger a switch, for example in the form of a spring-mounted switching drum over which the material is guided and which is arranged behind the take-off roller. Due to the increasing tension in the material, the spring used for storage is compressed until a position is reached in which a contact is triggered, which in turn is used to switch on the drive of the take-off roller.
If, on the other hand, the tension in the material subsides, for example due to a crack, the shift drum is pressed by the relaxing spring beyond the normal position against a second contact, which causes the drive to switch off immediately. Uncontrolled unwinding of the web is almost impossible.
Statt mit elastischem Material umwickelt kann die Abzugswalze aber auch als Saugwalze ausgebildet sein. In Abhängigkeit von der notwendigen Abzugskraft wird dabei der Unterdruck in der Abzugswalze vorgewählt, um einen sicheren Abzug des Material von der Rolle zu gewährleisten.Instead of being wrapped with elastic material, the take-off roller can also act as a suction roller be trained. Depending on the necessary deduction force The vacuum in the take-off roller is selected to ensure a safe removal of the material to ensure from the roll.
Insbesondere bei stark klebenden Materialien zeigt sich die Verwendung einer Führungswalze
zwischen Rolle und Abzugswalze als vorteilhaft. Die Führungswalze steht
über die gesamte Breite der Rolle in direktem Kontakt mit der Rolle, wobei der Abzug
des Materials über die Führungswalze mit der nichtklebenden Seite erfolgt. Ein Kontakt
zwischen Führungswalze und Abzugswalze beziehungsweise Abzugswalze und Rolle ist
nicht vorhanden.
Da die Führungswalze den Abzugswinkel des Materials von der Rolle verringert, was zu
einer weiteren Steigerung der Gleichmäßigkeit des Abzugs und damit einhergehend zu
einer Verringerung der Belastung des Materials führt, wird der Durchmesser der Führungswalze
so klein wie möglich gewählt. Allerdings bedingen die auftretenden Kräfte
während des Abzugs, die besonders bei breiten Rollen mit stark klebendem Material
erheblich sein können, daß der Durchmesser der Führungswalze nicht zu klein gewählt
werden kann. Denn es muß eine ausreichende Festigkeit der Führungswalze gewährleistet
sein.
Des weiteren resultiert aus der Verwendung der Führungswalze eine deutliche Verringerung
des Abzuggeräusches.
Die Führungswalze kann anstatt als Walze auch als Führungsprofil ausgeführt sein.In the case of strongly adhesive materials in particular, the use of a guide roller between the roller and the take-off roller has proven to be advantageous. The guide roller is in direct contact with the roller over the entire width of the roller, the material being drawn off via the guide roller with the non-adhesive side. There is no contact between guide roller and take-off roller or take-off roller and roller.
Since the guide roller reduces the take-off angle of the material from the roll, which leads to a further increase in the uniformity of the take-off and, consequently, to a reduction in the load on the material, the diameter of the guide roller is chosen to be as small as possible. However, the forces that occur during the take-off, which can be considerable, particularly in the case of wide rolls with strongly adhesive material, mean that the diameter of the guide roller cannot be chosen too small. This is because the guide roller must have sufficient strength.
Furthermore, the use of the guide roller results in a significant reduction in the trigger noise.
The guide roller can also be designed as a guide profile instead of a roller.
Die erfindungsgemäße Vorrichtung ist zum Abwickeln einer Vielzahl von selbstklebend beschichteten Materialien geeignet. Als besonders vorteilhaft stellt sich aber dar die Verwendung der Vorrichtung zum Abrollen von großflächigem, einseitig selbstklebend ausgerüstetem Material, das zum Schutz von Oberflächen Verwendung findet, bevorzugt von Oberflächen von Automobilkarosserien, ganz besonders bevorzugt von lackierten Automobilkarosserien.The device according to the invention is for unwinding a large number of self-adhesive coated materials. However, this is particularly advantageous Use of the device for unrolling large areas, self-adhesive on one side equipped material that is used to protect surfaces, preferred of surfaces of automobile bodies, very particularly preferably of painted ones Automobile bodies.
Die Vorrichtung ist bedingt durch die einfache konstruktive Gestaltung insbesondere bei breiten Materialbahnen geeignet, den Abwickelvorgang durch manuelles Ziehen am Material zu starten. Anschließend kann dann das von der Vorrichtung gelieferte Material in Handarbeit auf den gewünschten Flächen appliziert werden. Aber auch die Verwendung der erfindungsgemäßen Vorrichtung im semi-automatischen oder automatischen Applizieren ist ohne Einschränkung möglich.The device is due to the simple structural design in particular wide material webs, the unwinding process by manual pulling on Material to start. Then the material supplied by the device can then can be applied by hand on the desired surfaces. But also the use the device according to the invention in semi-automatic or automatic Application is possible without restriction.
Hinter der Vorrichtung kann das Material entsprechend weiterverarbeitet werden. So liegt auch die Kombination der Vorrichtung mit einer Schneidvorrichtung zur Herstellung abgelängter Stücke nicht außerhalb des Erfindungsgedankens. The material can be processed further behind the device. So is also the combination of the device with a cutting device for production cut pieces not outside the inventive concept.
Im folgenden sollen anhand zweier Figuren die erfindungsgemäße Vorrichtung sowie eine bevorzugte Ausführungsform derselben näher erläutert werden.In the following, the device according to the invention and a preferred embodiment of the same will be explained in more detail.
Wie in Figur 1 dargestellt, befindet sich die Rolle (1) mit dem selbstklebend beschichteten
Material zwischen zwei Halterungen (2), die auf einer Traverse (3) befestigt sind. Zur
Fixierung der Rolle (1) finden zwei Dorne (4) Verwendung, die in das Kernrohr (11) der
Rolle (1) eingeschoben sind. Jede der beiden Halterungen (2) weist eine U-förmige
Ausnehmung (21) auf. Durch die Neigung der Ausnehmung (21) ist gewährleistet, daß
die Rolle (1) bedingt durch die eigene Schwerkraft über die gesamte Breite der Rolle (1)
fest an der Abzugswalze (5) anliegt, in deren Inneren sich der Antriebsmotor (51) befindet.
Weiterhin ist auf der Abzugswalze (5) eine Schaumstoffauflage (52) als elastisches
Material aufgebracht.
Während des Betriebs treibt die Abzugswalze (5) die Rolle (1) an. An der Linie, an der
sich die Abzugswalze (5) und die Rolle (1) berühren, erfolgt gleichzeitig die Abnahme
des Materials (12) von der Rolle (1), und zwar wegen der Schaumstoffauflage (52)
besonders schonend, wobei das Material (12) mit der nichtklebenden Seite über die
Abzugswalze (5) läuft. Das Material (12) wird über die Abzugswalze (5) einer Schaltwalze
(6) zugeführt. Mit Hilfe der Feder (61) ist die Schaltwalze (6) je nach Spannung in
der Bahn des Materials (12) in der Lage, den Antriebsmotor (51) der Abzugswalze (5)
an- oder auszuschalten.
Nach der Schaltwalze (6) wird das Material (12) in die weiterverarbeitenden Schritte
geführt, die hier nicht näher dargestellt sind.As shown in Figure 1, the roller (1) with the self-adhesive coated material is between two brackets (2) which are attached to a cross member (3). Two mandrels (4) are used to fix the roller (1), which are inserted into the core tube (11) of the roller (1). Each of the two holders (2) has a U-shaped recess (21). The inclination of the recess (21) ensures that the roller (1) due to its own gravity over the entire width of the roller (1) is firmly against the take-off roller (5), inside which the drive motor (51) is located . Furthermore, a foam pad (52) is applied as an elastic material on the take-off roller (5).
During operation, the take-off roller (5) drives the roller (1). On the line at which the take-off roller (5) and the roller (1) touch, the material (12) is simultaneously removed from the roller (1), particularly gently because of the foam pad (52), the material (12) runs with the non-adhesive side over the take-off roller (5). The material (12) is fed via the take-off roller (5) to a switching roller (6). With the aid of the spring (61), the shift drum (6) is able, depending on the tension in the web of the material (12), to switch the drive motor (51) of the draw-off drum (5) on or off.
After the shift drum (6), the material (12) is guided into the further processing steps, which are not shown here.
In Figur 2 ist eine bevorzugte Ausführungsform der Vorrichtung gezeigt. Die Vorrichtung weist neben den bereits in Figur 1 beschriebenen Bauteilen zwischen der Rolle (1) und der Abzugswalze (5) die Führungswalze (7) auf, die aufgrund ihres geringen Durchmessers den möglichen Abzugswinkel des Materials (12) von der Rolle (1) stark einschränkt und damit zu einer nochmals verbesserten Abnahme des Materials (12) führt. Ein eigener Antrieb der Führungswalze (7) ist hierbei nicht vorgesehen.A preferred embodiment of the device is shown in FIG. The device has in addition to the components already described in Figure 1 between the roller (1) and the take-off roller (5) on the guide roller (7), due to its small diameter severely limits the possible withdrawal angle of the material (12) from the roll (1) and thus leads to an even better decrease in the material (12). Your own Drive of the guide roller (7) is not provided here.
