Definitions
- the invention relates to an embossing machine with a Impression cylinder and one under the impression cylinder horizontally movable stamp - a sheet-fed printing machine - being during stamping between stamp and Printing cylinder a film web arranged on the same Embossing foil and the material to be printed are guided.
- the Foil sheet is stored on a supply roll and laid down in sections on the stamp. After the printing or.
- the used section of the film web is embossed received by a winder, the Supply roll and the winding device on the Printing cylinder facing away from the stamp arranged are.
- Embossing machines for so-called sheet printing, also for Hot stamping foils have been known and used for a long time.
- the basic structure includes a stationary in the Embossing machine rotatably mounted around a horizontal axis Impression cylinder as well as a horizontally between an initial and an end position that can be moved back and forth Die; such a device is from the DE 92 09 706 U1 known.
- the embossing foil For printing or (embossing) embossing of a suitable material, such as paper, cardboard or plastic foil sheets, the embossing foil, which is usually only a few ⁇ m thick and is arranged on a foil web, is positioned on the stamp in such a way that it has its surface essentially completely covered.
- the stamp is drawn under the impression cylinder, the "pattern" of the embossing foil is transferred by the stamp to the material to be printed, which is also arranged to cover the stamp.
- the loading with unprinted or partly already printed sheets in standardized sizes such as 64 x 90 cm, 57 x 82 cm or 57 x 77 cm is known per se.
- the stamp itself is mounted horizontally, for example, on rollers or rollers which are guided in rails or the like, and can be moved relative to the printing cylinder.
- the stamp is moved, for example, with an appropriately controlled hydraulic system.
- the foil sheet with stamping foil is made from a supply roll in sections, d. H. the length of the sheet to be printed accordingly, unwound and positioned on the stamp.
- the section used is the Film web from a winding device, preferably in the form an empty role, resumed.
- the supply and Winding unit on the side facing away from the impression cylinder to arrange the movable stamp. So that can especially with larger diameter supply rolls accordingly longer film webs are used.
- a deflection device preferably in the form a roller rotatable about a further horizontal axis, deflected and runs below or in one in the stamp existing breakthrough back to that of the impression cylinder opposite side of the stamp, the Winding device in the direction of displacement of the stamp seen behind the supply roll.
- the transport of the film web takes place in the two devices mentioned above a feed roller and a pressure roller, between which the Foil web runs and is held.
- the preferred roller is included in the area of the winding device, essentially below from this, arranged. If the stamp is in a first Position in which it is under the impression cylinder is drawn out, a film web section is corresponding the length of the section to be embossed using the in Pulling direction behind the stamp arranged feed roller subtracted from the supply roll and with the help of one itself known control and regulating electronics above the stamp aligned. You can also use the film web Markings are attached, e.g. of optical sensors recorded and the measured values used for positioning.
- the stamp is in its second Move the position below the impression cylinder, whereby by the pressure of the pressure cylinder on the surface of the Stamp the relevant pattern or profile of the film from the Film web released and on one of the printing cylinder for the Printing process transported sheets of paper or cardboard is transmitted.
- the stamp with a Heating device to be provided to the stamp and thus the Heat the stamping foil up to 200 ° C to e.g. an adhesive to activate on or on the embossing foil and thus the To improve the embossing result.
- the tensile stress in the film can absolute change in length of the film web is not exact be predetermined. Even the compensation of this Linear expansion, for example with a smaller one Preference or the unwinding of a shortened accordingly Section of film from the supply roll, this effect can not compensate with sufficient accuracy. Due to the Tension is also the positioning of the film web and the film itself before stamping on the stamp lack of precision possible. Since the membrane over the Stamps are pulled due to the elastic stretch of the film material deviations from target positions, e.g. based on markings on the film and stamp will not be avoided.
- the preferred unit ends the Moves in due to the elasticity of the film material always a slight shift of that on the stamp overlying film section instead, which also has a predicted compensation is never complete is to be balanced.
- the invention is therefore based on the object Embossing machine for embossing foils using the sheet printing process works in such a way that the orientation of the Stamping foil or the foil web on the slidable Printing stamp is done with increased accuracy, also should are aimed at that the film material in the Embossing machine, especially in the area of the stamp and during the printing / embossing process, no tension, at least not subject to any significant tensile stress is not stretched and the tracing of the film web from the supply roll is largely suppressed.
- the main idea of the invention is that a Feed device is present between the supply roll and stamp is arranged. With this feed device the foil web comes from the supply roll the stamp fed.
- the basic difference is conventional embossing machines in that the film web not drawn over the stamp, but from the Feed device is pushed over the stamp.
- the means that the film web through the feed device, which are executed as shown later in the description can be pushed onto the stamp and there corresponding markings is positioned.
- the exhaustion the used sections of the film web on the Printing cylinder facing side of the stamp as well Wind up with an empty winder Role takes place in a manner known per se, preferably with Redirection of the used film web and passage under the stamp.
- the advantage of the invention is that due to the advance - pushing - of the film web on the stamp, no tensile stress occurs in the film material. Therefore there can be no stretch in the film web and thus in the film in the longitudinal direction.
- the film is unwound from the supply roll either with a separate drive for the supply roll or is taken over by the feed device.
- the traversing of the film web from the supply roll is also largely prevented with the arrangement of the feed device, since the film material is held between feed rolls of the feed device according to an embodiment shown in the description below and is unwound from the supply roll to the desired extent and, via the stamp is pushed. If the supply roll rotates slightly too far under certain circumstances, the film web section that is additionally unwound as a result is not transported further by the feed device to the stamp.
- the feed device is preferably a feed shaft with an associated pressure roller, the respective Axes of rotation parallel to the axes of rotation of the impression cylinder and the supply roll are aligned.
- the pressure roller is for example via a spring mechanism with a Section of its outer surface pressed against the feed shaft and the film web at this point of contact between Feed shaft and pressure roller kept slip-free.
- the feed shaft can be driven by an electric motor, the drive is carried out with a separate electric motor, or the shaft with an additional gear Drive motor for pressure cylinder and / or supply roll in Active connection is established.
- the feed shaft winds you up Film web section of the desired length from the supply roll and pushes it over the stamp into the desired position on the same.
- the exact alignment of the film web with film Regarding the stamp can with known markings Foil sheet and / or stamp and corresponding sensors and control electronics.
- the film web is either directly between the feed shaft and Pressure roller guided, or runs around the web with the embossing film first the pressure roller and then the feed shaft, as in the accompanying drawing. In this version is the slip of the film web due to static friction on the respective lateral surfaces of the roller and roller additionally reduced.
- materials for the outer surfaces of the roller and Role are the usual in embossing machine technology Hard plastics or rubbers suggested in comparable devices are known to the person skilled in the art.
- an alignment device between the feed device and the punch is provided in a further special configuration of the embossing machine.
- the section of the film web fed to the stamp and guided between the feed device and the aligning device also acts as a relaxation section for the film web if the section of the film web fed to the stamp and which passes through the feed device should still contain tensions.
- the stamping foil is fed to the stamp in alignment with the stamp surface.
- the alignment device consists of two mutually spaced deflecting rollers, between which the film web is guided.
- the mutual, vertical distance between the lateral surfaces of the deflection rollers is preferably selected such that the film web lies directly against only one of the lateral surfaces of the rollers, the stamping foil is therefore guided between the rollers and not pressed.
- the alignment device can be designed to be height-adjustable in order to give the section of the stamping film web located directly in front of the stamp a slight downward inclination, that is to say the vertical distance between the stamping film web and stamp is greater on the side facing away from the impression cylinder than on that side Printing cylinder facing.
- the height adjustability of the alignment device or the aforementioned inclination of the supplied section of the embossing film web can also be used to detach the film web heated during the embossing process from the stamp upwards after the embossing process, that is to say during the so-called return of the stamp.
- the choice of material for the rolls can be made as described above.
- the supply roll is also included to provide an additional drive that unwinds or the supply of the film web to the feed device or Stamp relieved. Especially with a new, heavy one Supply roll with an essentially still complete this is an advantage.
- the winding device can also be used in the same way be driven to the used, away from the stamp pushed film web on an initially empty take-up roll wind. It is driven by the Rewinder no significant tension on the Film web with the disadvantages described above Effects exerted, but only the film used tightened so that the same on their way from the stamp not sagging up to the take-up roll and therefore always moved within the range assigned to it.
- the respective drive of the supply roll and winding device via an electric motor and the feed device synchronous control of the motor can be done with any selectable control electronics and sensors for monitoring the tension in the different areas of the film web be carried out by a specialist.
- the axes of rotation are the Rollers are arranged at the ends of the rocker arms.
- the rocker is slightly biased against a spring force. at Tension occurs in the film web used the rocker rotates about its axis of rotation, one Length compensation in the film web and thus a removal to bring about the tension.
- the rocker Takes the tightness of the Film, the rocker is acted upon by it Spring force twisted in the opposite direction to the Length of the film web section that these rolls partially loops to extend.
- the spring force can with a tangential to the circumference of one with the axis of rotation of the rocker connected disc attacking tension spring on the seesaw be exercised.
- a coaxial Rotation axis of the rocker arranged spiral spring the required Apply spring force.
- This film storage also keeps the tightness in the Winding device to be fed film web automatically constant.
- a control signal from the rocker Dependence of the momentary rotation of the rocker around its horizontal axis to the drive motor of the Winding device are delivered. Takes the tightness for example from, i.e. the rocker is twisted by the spring, starts winding on the take-up device. at Increase in tightness, i.e. if the seesaw goes against the If the spring force is turned, the winding is ended.
- the stamp is height adjustable and lockable designed. This will make the vertical distance between the Surface of the stamp and the outer surface of the preferably installed fixed in space in the embossing machine Printing cylinder varies. In a simple way this can be done via a in the stamp in the feed direction of the film web or vertically to do this horizontally displaceable wedge, at least has an inclined surface with respect to the horizontal. He grabs a plate-shaped element, which with his the actual stamp surface forms, from the bottom, the bottom of such height adjustable element with one with the same Inclination angle like the wedge-provided sloping surface Is provided.
- the wedge lock to hold the stamp in a desired height can be determined by the expert in can be realized in any way.
- the control for operating the Embossing machine on the side of a swivel and / or telescopic arm attached which allows the operator to from any position with respect to the machine on the Access control.
- the pivotability of a support arm can have one or more swivel joints with vertical Axes of rotation can be reached.
- a locking device of the Swivel or telescopic mechanism of the support arm for the Control can be carried out in any way.
- Feeding the embossing foil web to the stamp can of course with all other types of embossing machines be applied. That means that the printing cylinder too itself can be designed to be movable relative to the stamp, or a printing or embossing process between two relative to each other movable stamp surfaces. It is crucial that one Feed device is present that the embossing film web or other material feeds the stamp, the Film web on the stamp, essentially parallel to it Stamp surface, pushed and aligned on the surface.
- the new method section for feeding and aligning an embossing foil in one Embossing process uses an embossing machine that has the characteristics has at least one of claims 1 to 9.
- the Embossing machine according to the invention is between the Supply roll and the stamp a feed device arranged, the sections of the embossing film Feeds stamps and aligns them; there the section in question is not in the feed direction loaded in tension.
- Invention is an embossing machine with a can be rotated in the base of the embossing machine "P" stored printing cylinder 12 with which to be printed Material kept at least during the printing process and to be led.
- a stamp 10 is horizontal "R1" among the Printing cylinder 12 movable, the actual printing or Embossing process on the section of the lateral surface of the Printing cylinder 12 takes place directly on the stamp 10th rests.
- an additional and discharge device for the usually in standard sizes to be printed paper or cardboard sheets 25 not shown.
- the embossing foil web 4, here with the feed device “V” is unwound in sections from the supply roll 5 and fed to the stamp 10 with the feed device “V” and by means of the alignment device 9.
- the feed device “V” consists of a rotatably mounted feed shaft 7 and a rotatably mounted pressure roller 8, the lateral surfaces of which, for example, are pressurized to one another at least in sections with a spring acting on the axis of rotation of the pressure roller 8.
- the course of the film / web 4 is designed here in such a way that it first runs around the pressure roller 8, is passed between the pressure roller 8 and feed shaft 7 and then runs around the feed shaft 7.
- the supply roll 5 can advantageously be equipped with a preferably selectively switchable electric motor drive in order to facilitate the unwinding, in particular, of a filled supply roll 5.
- the film web 4 is guided over the heatable surface of the stamp 10, whereby it can be aligned vertically with respect to the surface of the stamp 10 with an alignment device 9 in the form of two height-adjustable, vertically spaced, rotatable rollers.
- the used (embossed) section of the film web 4 can also be detached from the heated stamp surface, which is preferably done when the stamp is returned in order to further facilitate the advancement of a new web section, thereby stressing the film web and the Film is lowered by another.
- a film deflection by 180 ° preferably in the form of a further rotatable roller 16 is attached in order to return the used film web 4a below or in an opening provided for this purpose in the stamp 10 and to take it up on a winding device

- a different spring force is exerted on the rocker depending on the position of the rocker. For example, if the tightness in this area of the film web 4a diminishes, ie if a new section of film web 4 is fed by the feed device, the rocker rotates to save the length of the pushed used section of the film web until a motor drive 3 of the winding roll 2 responds and winds up the relevant length of the used film web 4a.
- the tightness in the film memory 4a in the film web 4a used changes into a slight tensile stress and the rocker is rotated against the spring force in such a way that the length of the section of the film web 4a surrounding the rollers is shortened until the motor drive 3 of the take-up roll 2 stops.
- the winding process is preferably started and stopped using switches which are controlled by the rotary movement of the rocker. Below the rocker there is preferably a further deflection 21 for the film web 4a used in order to feed the same 4a to the film store 22 in the correct position.

Abstract
Description
Der Stempel selbst ist beispielsweise auf Rollen oder Walzen, die in Schienen oder dergleichen geführt sind horizontal, relativ zum Druckzylinder verfahrbar gelagert. Der Stempel wird z.B. mit einer entsprechend gesteuerten Hydraulik verfahren.
Die Abwicklung der Folie von der Vorratsrolle erfolgt entweder mit einem separaten Antrieb für die Vorratsrolle oder wird von der Vorschubeinrichtung mit übernommen. Auch das Nachfahren der Folienbahn von der Vorratsrolle ist mit der Anordnung der Vorschubeinrichtung weitestgehend unterbunden, da das Folienmaterial gemäß einer in der Beschreibung weiter hinten beispielhaft dargestellten Ausgestaltung zwischen Vorschubwalzen der Vorschubeinrichtung gehalten ist und genau in gewünschtem Maße von der Vorratsrolle abgewickelt und, über den Stempel geschoben wird. Dreht sich die Vorratsrolle unter Umständen dennoch geringfügig zu weit, so wird der dadurch zusätzlich abgewickelte Folienbahnabschnitt von der Vorschubeinrichtung nicht zum Stempel hin weitertransportiert.
Zusätzlich kann die Ausrichteinrichtung höhenverstellbar ausgeführt sein, um den unmittelbar vor dem Stempel befindlichen Abschnitt der Prägefolienbahn, in Vorschubrichtung gesehen, eine geringfügige Neigung abwärts zu verleihen, d. h. der vertikale Abstand zwischen Prägefolienbahn und Stempel ist an der dem Druckzylinder abgewandten Seite größer als an der dem Druckzylinder zugewandten. Die Höhenverstellbarkeit der Ausrichteinrichtung, bzw. die vorgenannte Neigung des zugeführten Abschnittes der Prägefolienbahn kann auch dazu verwendet werden, die bei dem Prägevorgang erwärmte Folienbahn nach dem Prägevorgang, also beim sogenannten Rücklauf des Stempels, vom Stempel nach oben hin abzulösen.
Die Materialwahl der Rollen kann wie oben beschrieben erfolgen.

- die Anordnung von Heizdrähten im Stempel.
Die Vorschubeinrichtung "V" besteht aus einer drehbar gelagerten Vorschubwelle 7 und einer drehbar gelagerten Anpresswalze 8, deren Mantelflächen beispielsweise mit einer an der Drehachse der Anpresswalze 8 angreifenden Feder zumindest abschnittsweise zueinander mit Druck beaufschlagt sind. Der Verlauf der Folie/-bahn 4 ist hier derart ausgelegt, dass sie zuerst die Anpresswalze 8 umläuft, zwischen Anpresswalze 8 und Vorschubwelle 7 hindurchgeführt ist und anschließend die Vorschubwelle 7 umläuft. Durch die Haftreibung zwischen dem Material der jeweiligen Mantelflächen sowie der Folienbahn 4 und der Anpresswirkung tritt kein Schlupf zwischen der Vorschubeinrichtung "V" und der Folienbahn 4 auf.
Vorteilhaft kann die Vorratsrolle 5 mit einem vorzugsweise wahlweise zuschaltbaren elektromotorischen Antrieb ausgestattet werden, um das Abwickeln insbesondere einer gefüllten Vorratsrolle 5 zu erleichtern. Die Folienbahn 4 ist über die beheizbare Fläche des Stempels 10 geführt, wobei sie mit einer Ausrichteinrichtung 9 in Form zweier höhenverstellbaren, vertikal beabstandeten, drehbaren Walzen bezüglich der Oberfläche des Stempels 10 vertikal ausgerichtet werden kann. Mit der höhenverstellbaren Ausrichteinrichtung 9 kann auch der benutzte (geprägte) Abschnitt der Folienbahn 4 von der erhitzten Stempelfläche nach oben abgelöst werden, was bevorzugt beim Zurückführen des Stempels erfolgt, um den Vorschub eines neuen Bahnabschnittes weiter zu erleichtern, wodurch die Beanspruchung der Folienbahn und der Folie um ein Weiteres gesenkt wird.
Die Aufwickelvorrichtung ist ebenfalls an der dem Druckzylinder 12 abgewandten Seite des Stempels 10 angeordnet. Die Aufwickeleinrichtung besteht aus einer Rolle 2, deren grundsätzlicher Aufbau und Dimensionierung der Vorratsrolle 5 entspricht, sowie einem sog. Folienspeicher 22, bestehend aus einer um eine Drehachse schwenkbar gelagerten Wippe mit zwei ihrerseits drehbaren Walzen, mit denen die Folienbahn 4a geführt ist, wobei die Folienbahn 4a diese Walzen teilweise umschlingt.
Stoppt die Vorschubbewegung der Folienbahn 4, geht im Bereich des Folienspeichers 22 in der benutzten Folienbahn 4a die Straffheit in eine leichte Zugspannung über und die Wippe wird entgegen der Federkraft derart verdreht, dass die Länge des die Walzen umlaufenden Abschnitts der Folienbahn 4a verkürzt wird, bis der motorische Antrieb 3 der Aufwickelrolle 2 stoppt. Das Starten und Stoppen des Aufwickelvorgangs erfolgt bevorzug mit Schaltern, die von der Drehbewegung der Wippe angesteuert werden. Unterhalb der Wippe ist vorzugsweise eine weitere Umlenkung 21 für die benutzte Folienbahn 4a vorhanden, um selbige 4a dem Folienspeicher 22 lagerichtig zuzuführen.
Es ist die Anordnung segmentierter Vorratsrollen 5, 5', 5", 5"' und Aufwickeleinrichtungen 2, 2', 2", 2"' schematisch dargestellt. Die Prägemaschine weist, in Vorschubrichtung 14 gesehen, vier nebeneinander angeordnete Folienbahnen 4, 4', 4", 4"' auf, wobei benachbarte Vorratsrollen 5, 5', 5", 5"' in Vorschubrichtung 14 horizontal beabstandet sind. Mit einer derartigen Anordnung können unterschiedliche Folien 4 geprägt werden. Dementsprechend kann auch die Stempelfläche in unterschiedliche Segment-Bereiche, insbesondere mit voneinander unabhängigen Heizeinrichtungen 17, aufgeteilt sein.
