Description
Die Erfindung betrifft eine Vorrichtung zum Anbringen eines Prägefolien-Abdruckes auf einer flexiblen Materialbahn mit einer beheizten Prägewalze und mit mindestens einer Andruckrolle, mittels welcher Prägefolie und Materialbahn gegeneinander und gegen die Oberfläche der Prägewalze drückbar sind.The invention relates to a device for applying an embossing foil impression on a flexible material web with a heated embossing roller and with at least one pressure roller, by means of which embossing foil and material web can be pressed against one another and against the surface of the embossing roller.
Eine derartige Vorrichtung ist aus der DE 32 10 551 C2 bekannt. Dort sind eine Anzahl Andruckrollen jeweils paarweise zusammengefasst an einem Rollenkorb vorgesehen. Die Andruckrollen können einzeln verstellt werden, wobei zuerst eine oder zwei benachbarte innere Andruckrollen und dann nach aussen fortschreitend die weiteren Andruckrollen zur Anlage an der Prägewalze bringbar sind. Insbes. bei empfindlichen flexiblen Materialbahnen wie bspw. Banknotenpapier ist es mit dieser bekannten Vorrichtung nicht sicher auszuschliessen, dass es infolge des vollflächigen Aufeinanderpressens zwischen Andruckrolle und Prägewalze zu einer unerwünschten Komprimierung der Fasern der flexiblen Materialbahn und somit zu einer unerwünschten Veränderung der Eigenschaften der flexiblen Materialbahn kommt.Such a device is known from DE 32 10 551 C2. There a number of pinch rollers are provided in pairs on a roller basket. The pressure rollers can be adjusted individually, whereby first one or two adjacent inner pressure rollers and then progressively outwards the other pressure rollers can be brought into contact with the embossing roller. Esp. In the case of sensitive flexible material webs such as, for example, banknote paper, it cannot be reliably ruled out with this known device that the full-surface pressing between the pressure roller and the embossing roller leads to undesired compression of the fibers of the flexible material web and thus to an undesirable change in the properties of the flexible material web.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mit welcher auch bei empfindlichen flexiblen, mit einem Prägefolienabdruck zu beprägenden Materialbahnen eine unerwünschte Komprimierung der Fasern der flexiblen Materialbahn und damit eine unerwünschte Veränderung der Eigenschaften der flexiblen Materialbahn vermieden wird, ohne dass hierdurch die Arbeitsgeschwindigkeit der Vorrichtung beeinträchtigt wird.The invention is therefore based on the object of providing a device of the type mentioned at the outset, with which undesirable compression of the fibers of the flexible material web and thus an undesired change in the properties of the flexible material web is avoided even with sensitive flexible material webs to be imprinted with an embossing foil impression without affecting the operating speed of the device.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die/jede Andruckrolle mit einer Einstelleinrichtung zur definierten Einstellung des Abstandes der entsprechenden Andruckrolle relativ zur Prägewalzenoberfläche und damit zur definierten Einstellung des von der Andruckrolle auf die Prägefolie und die Materialbahn ausgeübten Drukkes versehen ist. Mit der erfindungsgemässen Vorrichtung ist es folglich möglich, durch geeignete Einstellung des Abstandes der entsprechenden Andruckrolle relativ zur Prägewalzenoberfläche in Abhängigkeit von der Wanddicke der flexiblen, zu beprägenden Materialbahn und in Abhängigkeit von der Wanddicke der Prägefolie den Prägedruck zwischen der Prägewalze und der mindestens einen Andruckrolle passend einzustellen, so dass in vorteilhafter Weise auch bei der Beprägung empfindlicher flexibler Materialbahnen wie z.B. Banknotenpapier eine unerwünschte Komprimierung der Papierfasern der Materialbahn und somit eine Veränderung der Papiereigenschaften vermieden wird. Ausserdem ergibt sich durch die erfindungsgemässe Ausbildung der Vorrichtung der Vorteil, dass Wärmedehnungen der Prägewalze kompensiert werden, d.h. es ergeben Wärmedehnungen der Prägewalze keine Abstandsänderungen zwischen der Prägewalze und der/jeder Andruckrolle.This object is achieved according to the invention in that the / each pressure roller is provided with an adjusting device for the defined adjustment of the distance of the corresponding pressure roller relative to the embossing roller surface and thus for the defined adjustment of the pressure exerted by the pressure roller on the embossing film and the material web. With the device according to the invention, it is consequently possible, by suitably adjusting the distance of the corresponding pressure roller relative to the embossing roller surface, as a function of the wall thickness of the flexible material web to be embossed and as a function of the wall thickness of the embossing film, to match the embossing pressure between the embossing roller and the at least one pressure roller adjust so that it is advantageous when embossing sensitive flexible material webs such as Banknote paper an undesired compression of the paper fibers of the material web and thus a change in the paper properties is avoided. In addition, the design of the device according to the invention has the advantage that thermal expansions of the embossing roller are compensated for, i.e. thermal expansion of the embossing roller does not result in changes in the distance between the embossing roller and the / each pressure roller.
Eine vorteilhafte Ausbildung der erfindungsgemässen Vorrichtung wird erzielt, wenn die Einstelleinrichtung ein Paar Abstandsringe aufweist, die an den beiden voneinander entfernten Endabschnitten einer Achse vorgesehen sind, an der die entsprechende Andruckrolle gelagert ist, wobei die Abstandsringe an der entsprechenden Achse exzentrisch gelagert sind. Hierbei ist es zweckmässig, wenn die beiden Abstandsringe der Einstelleinrichtung einer Andruckrolle jeweils an einer zugehörigen Exzenterhülse gelagert sind, die an der Achse der entsprechenden Andruckrolle befestigt ist. Hierbei ist es möglich, dass an einer entsprechenden Achse eine einzige Andruckrolle vorgesehen ist, oder eine Anzahl Andruckrollen -vorzugsweise voneinander beabstandetvorgesehen sind. Durch Ausbildung der Vorrichtung mit der mindestens einen Einstelleinrichtung ist es einfach und problemlos möglich, den Abstand zwischen der mindestens einen zu einer Achse zugehörigen Andruckrolle und der Prägewalzenoberfläche durch Verdrehung der Achse und demzufolge durch Verdrehung der an der Achse fixierten Exzenterhülsen sehr genau einzustellen, wobei die zu den beiden Exzenterhülsen zugehörigen Abstandsringe in jeder beliebigen Drehwinkelstellung der entsprechenden Achse an der Prägewalze anliegen.An advantageous embodiment of the device according to the invention is achieved if the adjusting device has a pair of spacer rings which are provided on the two end sections of an axle which are at a distance from one another and on which the corresponding pressure roller is mounted, the spacer rings being mounted eccentrically on the corresponding axle. Here, it is expedient if the two spacer rings of the setting device of a pressure roller are each mounted on an associated eccentric sleeve which is fastened to the axis of the corresponding pressure roller. It is possible here for a single pressure roller to be provided on a corresponding axis, or for a number of pressure rollers to be provided, preferably spaced apart from one another. By designing the device with the at least one setting device, it is easy and straightforward to set the distance between the at least one pressure roller associated with an axis and the embossing roller surface by rotating the axis and consequently by rotating the eccentric sleeves fixed to the axis, the The spacer rings belonging to the two eccentric sleeves bear against the embossing roller in any rotational angle position of the corresponding axis.
Jede Einstelleinrichtung kann ein manuell zu betätigendes Einstellorgan aufweisen. Bei diesem Einstellorgan handelt es sich bspw. um einen Drehknopf mit einer Skala, die mit einer an der Vorrichtung ortsfest vorgesehenen Markierung zusammenwirken kann. Das manuell zu betätigende Einstellorgan ist also vorzugsweise zur Veränderung der Drehwinkelstellung der Achse der entsprechenden, in der Andruckposition befindlichen Andruckrolle in Bezug auf die Prägewalze vorgesehen.Each setting device can have a manually operated setting element. This setting element is, for example, a rotary knob with a scale that can interact with a marking provided on the device in a stationary manner. The manually operated adjusting member is therefore preferably provided for changing the angle of rotation position of the axis of the corresponding pressure roller located in the pressure position with respect to the embossing roller.
Eine besonders vorteilhafte Ausbildung der erfindungsgemässen Vorrichtung, für welche ein selbständiger Patentschutz beantragt wird, ergibt sich, wenn die axiale Breite der/jeder Andruckrolle kleiner als die axiale Breite der Prägewalze ist. Hierbei kann das Verhältnis von axialer Breite der/jeder Andruckrolle zur axialen Breite der Prägewalze bspw. zwischen 0,8 und 0,05 liegen, oder grösser oder kleiner sein. Eine solche Ausbildung der Vorrichtung weist insbes. bei kleinem Quotienten den Vorteil auf, dass die Prägewalze im Vergleich zur Breite der zu beprägenden flexiblen Materialbahn relativ breit ausgebildet sein kann, so dass in axialer Richtung der Prägewalze im Bereich der Andruckrolle ein quasi gleichbleibender Temperaturverlauf gegeben ist, was sich auf das Prägeverhalten zwischen der Prägewalze und der im Vergleich hierzu relativ schmalen mindestens einen Andruckrolle positiv auswirkt. Bei einer Vorrichtung der zuletzt genannten Art ist es vorteilhaft, wenn die Andruckrolle in einem Abstand von mindestens einem der Abstandsringe angeordnet und im Zwischenraum zwischen der Andruckrolle und dem entsprechenden Abstandsring eine Stützrolle vorgesehen ist, die einen geringfügig kleineren Durchmesser besitzt als die Andruckrolle. Mit Hilfe der im Zwischenraum zwischen der Andruckrolle und dem entsprechenden Abstandsring vorgesehenen Stützrolle wird ein Umknicken der flexiblen Materialbahn infolge der vergleichsweise schmalen Auflage auf der im Vergleich zur Prägewalze schmalen mindestens einen Andruckrolle vermieden, so dass ohne Beeinträchtigung der emfpindlichen flexiblen Materialbahn, d.h. ohne unerwünschte Komprimierung und daraus resultierender Veränderung der Materialeigenschaften eine hohe Arbeitsgeschwindigkeit realisierbar ist. Demselben Zweck dient es, wenn die mindestens eine Stützrolle eine axiale Länge aufweist, die an den Abstand zwischen der Andruckrolle und dem zugehörigen Abstandsring angepasst ist.A particularly advantageous embodiment of the device according to the invention, for which an independent patent protection is sought, is obtained if the axial width of the / each pressure roller is smaller than the axial width of the embossing roller. The ratio of the axial width of the / each pressure roller to the axial width of the embossing roller can be, for example, between 0.8 and 0.05, or larger or smaller. Such a design of the device has the advantage, in particular, with a small quotient that the embossing roller can be made relatively wide compared to the width of the flexible material web to be embossed, so that in the axial direction of the embossing roller there is a virtually constant temperature profile in the area of the pressure roller , which affects the embossing behavior between the embossing roller and the relatively narrow at least a pinch roller has a positive effect. In a device of the last-mentioned type, it is advantageous if the pressure roller is arranged at a distance from at least one of the spacer rings and a support roller is provided in the space between the pressure roller and the corresponding spacer ring, which has a slightly smaller diameter than the pressure roller. With the aid of the support roller provided in the space between the pressure roller and the corresponding spacer ring, the flexible material web is prevented from twisting as a result of the comparatively narrow support on the at least one pressure roller, which is narrow in comparison to the embossing roller, so that the sensitive flexible material web is not impaired, that is to say without undesired compression and the resulting change in material properties enables a high working speed to be achieved. It serves the same purpose if the at least one support roller has an axial length which is adapted to the distance between the pressure roller and the associated spacer ring.
Bei einer Vorrichtung, bei welcher voneinander beabstandete und zueinander achsparallel angeordnete Andruckrollen jeweils zu Andruckrollen-Paaren zusammengefasst an Wippen gelagert und in zwei Gruppen symmetrisch zur Prägewalze angeordnet sind, ist es vorteilhaft, wenn jeweils nur der äussersten Andruckrolle der beiden Andruckrollen Gruppen Stützrollen zugeordnet sind. Die Prägung findet in jedem Fall nur im Bereich zwischen der Prägewalze und der mindestens einen im Vergleich zur Prägewalze in axialer Richtung schmal ausgebildeten Andruckrolle statt.In the case of a device in which pressure rollers which are spaced apart from one another and are arranged axially parallel to one another are in each case mounted on rockers in pairs of pressure rollers and are arranged symmetrically to the embossing roller in two groups, it is advantageous if support rollers are assigned to only the outermost pressure roller of the two pressure roller groups. The embossing only takes place in the area between the embossing roller and the at least one pressure roller, which is narrow in the axial direction compared to the embossing roller.

Im zuletzt genannten Fall sind die Andruckrollen 24 an der zugehörigen Achse 20 vorzugsweise voneinander beabstandet angeordnet. Hierbei kann der Abstand zwischen den einzelnen Andruckrollen auch einstellbar sein. Die drehbare Lagerung der/jeder Andruckrolle 24 auf der Achse 20 erfolgt mittels an sich bekannter Wälzlager 26.
