Abstract

For transferring an image-wise coating from a carrier film to a printing sheet, an image-wise adhesive application is applied to the printing sheet. In a film transfer module (2), the carrier film with the image-wise coating is then guided past the printed sheet under contact pressure, so that the coating adheres to the splices and an image is formed. To improve the function, to simplify the device and to increase the flexibility is provided to provide a receptacle for film rolls of the transfer film (5), which provides a simplified handling.

Description

The The invention relates to a device for transferring imaging layers from a carrier film on printed sheet according to the preamble of claim 1

It is known to produce metallic layers on printed sheets by means of a film transfer process. So is in the EP 0 569 520 B1 a printing material and a printing apparatus using this material are described. In this case, a sheet-processing machine is shown, which has a feeder and a boom, between which two units printing units and a film transfer module are arranged. In at least one of the printing units, an adhesive pattern is applied by means of the planographic printing process. This adhesive pattern is applied in a cold printing process and has a specific imaging subject. In the printing unit following the film transfer module with a counter-pressure cylinder and a transfer cylinder, a film guide is provided.

These is designed in the way that from a film supply roll Foil strip or a transfer foil through the transfer nip of the Film transfer module between the impression cylinder and the transfer cylinder to be led. The foil strip is on the outlet side wound up again after leaving the film transfer module. The transfer film has a carrier layer on which Imaging layers such as metallic layers, for example Aluminum, can be applied. When transporting Printing sheet through the printing unit will print each sheet with an adhesive pattern Mistake. Thereafter, the sheet is passed through the film transfer module led, by means of the transfer cylinder on the Impression cylinder resting sheet with the film material is associated. It goes down the metallic Layer a close connection with the areas provided with adhesive on the sheet. After further transporting the print sheet The metallic layer adheres only in the area of adhesive provided pattern. The carrier film is thus the metallic Layer removed in the area of Klebstoffmus ter. The way this way used transfer film is wound up again. The print sheet is designed in the coated state.

It is known such film transfer modules, for example in printing units of printing presses. A disadvantage of the known devices is that they are not flexible and that the consumption on transfer film is expensive.

Furthermore, from the DE 10 2006 015 466 A1 a film transfer unit with friction shaft known. There, the film or partial film rolls are mounted on a by means of friction a drive or braking force transmitting shaft. The friction effect is limited to narrow areas. These independently allow a rotation of the roller receptacle, so that a plurality of partial film rolls can be accommodated side by side on the shaft. The recorded film rolls can therefore run with different peripheral speeds or speeds. The web tension of the film webs removed from the film rolls can nevertheless be kept within a tolerance range. The rubbing driving shafts may be disposed on the roll-off side or on the sheet-collecting side.

adversely on this device is the poor handling for placement the film or partial film rolls on only one axis. It can Medium film rolls are only then replaced when the film rolls at least one edge region previously removed from the shaft. Farther is an independent regulation of friction or braking forces not for different film or partial film rolls possible.

task The invention is to provide a device with which the carry an imaging layer z. A metallization layer, can be economical and accurate, the device simple should be manageable.

The Solution to this problem arises according to the Features of claim 1.

The transfer gap 6 in the film transfer module 2 is through a transfer cylinder 3 and an impression cylinder 4 educated. The transfer cylinder 3 may correspond to a blanket or form cylinder of a known offset printing unit or paint module of a sheet-fed offset printing press. Within the film transfer module 2 is a web guide for transfer films 5 shown.

The Device can also be integrated as an integrated foil transfer module FA be arranged a printing unit.

In the basic representation after 1 is a foil supply roll 8th the film transfer module 2 assigned on the side of the sheet feeder. The foil supply roll 8th has a rotary drive 7 on. The rotary drive 7 becomes the continuous controlled feeding of the transfer film 5 to the film transfer module 2 needed and is therefore controllable. Furthermore, in the field of Folienzu- and -abführung Leiteinrichtungen 14 , As deflecting or tensioning rollers, pneumatically actuated conducting means, baffles o. Ä. Provided. Thus, the film web of Transferfo lie 5 always guided without distortions and in the same voltage compared to the transfer cylinder 3 being held.

The transfer foil 5 can order the transfer cylinder 3 be guided around, with the transfer film 5 advantageously only from one side of the film transfer module 2 out to the transfer gap 6 can be added and removed (see dashed diagram). Furthermore, the transfer film 5 also essentially tangential to the transfer cylinder 3 or this only in a small circumferential angle wrapped in the transfer nip 6 be guided. Here is the transfer foil 5 on one side of the film transfer module 2 on and off to the opposite side. On the discharge side of the printing unit is a film collecting roll 9 represented by which used sheet material is wound up. Again, a rotary drive 7 provided, which is controllable.

Furthermore, in the film transfer module 2 or FA supplementary dryer 16 be arranged to pre-dry the adhesive on the substrate and / or ready to dry the finished coating. By means of an inspection device 17 the coating quality can be observed. Finally, in the film transfer module 2 or FA cleaning devices R may be provided to from the film web of the transfer film 5 remove any sloping and, if necessary, adhering to the cylinders impurities from the machine.

In the 2 to 5 Inventive devices for receiving film rolls are shown.

In 2 is a facility in the Ausfüh form with a single receiving module 19 for film rolls 20 . 21 shown on the film transfer module 2 or FA is set up. The recording module 19 is with two axes 22 . 23 for holding film rolls 20 . 21 Mistake. On every axis 22 . 23 can corresponding to one another in the transport direction of the sheet to be coated sheet parallel processing traces one or more rolls of film 20 . 21 be held.

The feeding of the transfer film 5 to the transfer gap 6 occurs from one or more on the lower axis 22 retained film rolls 20 on the right side of the film transfer module 2 or FA. The return of the used transfer film 5 takes place from the transfer gap 6 out parallel to the film transfer module 2 or FA up to one or more on the upper axis 23 retained film rolls 21 , All axes 22 . 23 Can be used to drive or brake the film rolls 20 . 21 be provided with rotary actuators.

Below the lower axis 22 or the content of the film rolls held there 20 is a web tension unit 24 arranged. The web tension unit 24 can be designed as a retractable module. It has several guide rollers 25 on, according to the required web tension of the film web 5 are adjustable with respect to their path. The adjustment can be regulated as a function of the web tension.

Depending on the number of corresponding to the processing tracks on the axis 22 arranged film rolls 20 can parallel to each other and several web tension units 24 be arranged as exchangeable modules.

In This arrangement can thus both with a format width or to work with several part-width film webs.

In 2.1 is the embodiment according to 2 through an additional web tension unit 24.1 added in the area of film removal. So the discharged foil web can 5 even after the transfer gap 6 and before winding on the film roll 21 additionally be adapted in their web tension. This is especially at a timing of the film feed advantage.

The web tension units 24 . 24.1 may alternatively be provided as storage units with multiple pulleys. These pulleys can be provided in the manner of a loop memory for the web feed on web-fed rotary printing presses, wherein the guide rollers in pairs form a web loop, which in the absence of train replenishment, z. B. at standstill of the feeding web roll, can be shortened for temporary web feed until the web replenishment of a supply reel begins again. In this embodiment, the web tension units become 24 . 24.1 also used for functions of the so-called format clocking or channel clocking.

In 3 is a device with a first recording module 19 for film rolls 27 . 28 according to 2 and a second receiving module 26 for film rolls 30 . 31 shown. The first recording module 26 is on the film transfer module 2 or FA and the second recording module 29 is on a downstream printing or processing plant 32 the sheet processing machine put on. Each of the recording modules 26 . 29 is with two axes each 33 . 34 respectively. 35 . 36 for holding film rolls 27 . 28 respectively. 30 . 31 Mistake. On each of the axles 33 . 34 respectively. 35 . 36 can according to the processing traces to be supplied on the sheet to be coated one or more rolls of film 27 . 28 respectively. 30 . 31 be held.

All axes 33 . 34 respectively. 35 . 36 can use rotary actuators to drive or brake the film rolls 27 . 28 respectively. 30 . 31 be provided.

As well more than two axes can be arranged per module, to accommodate more rolls of film for unwinding or unrolling. In order to can be a variety of film rolls for record a corresponding number of processing traces in the modules. The The following comments on film handling apply accordingly Also for modules with more than two axes to accommodate Film rolls.

The feeding of the transfer film 5 to the transfer gap 6 is done by one or more film rolls 27 . 28 from the first recording module 26 out. Here, the transfer film 5 per processing track either from on the lower axis 33 retained film rolls 27 or from on the upper axis 34 retained film rolls 28 off on the right side of the film transfer module 2 or FA the transfer gap 6 be supplied.

The return of the used transfer film 5 takes place from the transfer gap 6 out parallel to the film transfer module 2 or FA to the second recording module 29 and to its upper and lower axis 35 . 36 retained film rolls 30 . 31 ,

In the first recording module 26 is below the lower axis 33 or the film rolls held there 27 a web tension unit 37 arranged. The web tension unit 37 can be designed as a retractable module. It has a plurality of guide rollers, which are adjustable in accordance with the required web tension of the film web with respect to the path thereof. The adjustment can be regulated as a function of the web tension.

Depending on the number of required processing tracks on the axes 33 . 34 arranged film rolls 27 . 28 can parallel to each other and several web tension units 37 be arranged as exchangeable modules. Furthermore, the upper axis 34 or the film rolls held thereon 28 one or more responsive web tension units 38 assigned.

Also in the last-described arrangement, both with one each format widths or with several part-width film webs or accordingly required processing tracks arranged transfer foils worked become.

The Arrangement also allows operation according to a quick-change concept, in which several rolls of film per processing track can be used. Furthermore, one within the printing machine with film rolls equipable device created in the manner of a Reel changer is operable.

This can be in the after 3 described recording module 26 a supply roll 28 for transfer film 5 already on a free axis 34 be provided while the active film roll 27 is processed. At or shortly before the complete consumption of the transfer film 5 can the supply roll 28 by gluing with the active film roll 27 be connected at a standstill. This can be done semi-automatically, manually or with auxiliary means. This allows the new transfer film from the new film roll 28 directly by means of the currently processed transfer film into the film transfer module 2 be confiscated.

In conjunction with this, the system described can also be automated. For this purpose, in a magazine, for. B. in conjunction with a web tension unit 37 respectively. 38 for the running transfer film from the active film roll 27 a sufficient amount of transfer film 7 get saved. Then a bond between the active film roll 27 and the new roll of film to be used 28 respectively. With appropriate acceleration of the subsequently used film roll 28 , possibly down to machine speed, the change process between old and new film roll is reduced 27 respectively. 28 so strong that almost a continuous roll change takes place. This is also a full automation possible, as is common in automatic reel splicers in web-processing printing machines.

In this case, the conventional arrangement of the film transfer module remains over two printing towers, as in 1 shown, received.

In this case, the winding film rolls 30 . 31 also be arranged twice. Even if an automated roll change from a full to an empty take-up roll is realized there, the processes for upgrading and disassembling can be carried out during idle times or by auxiliary power with minimal or even no production stoppages.

Furthermore, the arrangement can be improved by loading and unloading the axles 22 respectively. 33 . 34 and 23 respectively. 35 and 36 the recording modules 19 respectively. 26 and 29 on the front sides, z. B. from the back of the printing machine ago. Here, the film rolls are designed as mandrel axes z. B. postponed in sleeve technology. This can be done by means of the simplest means of transport, eg. B. done with a lift truck.

Advantageously, after 3 into the recording modules 26 . 29 integrated hoists 50 . 51 available. This results in an even smaller space requirement for roll change. The hoists 50 . 51 are each on one of the recording modules 26 . 29 the coating device 2 arranged. They are the respective installation location of the film rolls in the recording modules 26 . 29 so close that a very compact arrangement is created. Therefore, with the hoist 50 the installation of the fresh film rolls on the roll-off side in the receiving module 26 respectively. Furthermore, by means of the hoist 51 the removal of the filled composite rollers on the roll-up from the receiving module 29 respectively.

This can axes 22 respectively. 33 . 34 and 23 respectively. 35 and 36 be used, the storage is unilateral and thus self-supporting. The lower weights of the narrow film rolls make this possible. For this purpose, the respective laterally end-side receptacles are preferably designed as self-supporting axes. All device variants with more than one receptacle for film rolls are suitable for this purpose. The self-supporting axles can, if their free ends point to each other, also be used together to accommodate format-wide film rolls.

A device usable for this purpose is in 4 shown. This is particularly suitable over the width of the device offset from each other arranged Teilfolienbahnen record. This can be done on the sheet partially a film transfer. This is possible in partial areas or in adjacent areas with different types of films.

According to 4 are two rolls of film 27 and 39 axially offset side by side on the axis 33 arranged and a roll of film 28 is on the axes 34 in turn axially offset to the other two rolls of film 27 . 39 arranged. The axis 33 can to have two role recordings or be carried out in two parts. The axial position of the film rolls 27 . 39 and 28 form in their position and width determinable processing traces for the partial film webs of the transfer film 5 , The partial film webs from the film rolls 27 . 39 and 28 can via a guide roller 42 three on top of each other in the recording module 26 web tension units arranged below the roll holders 37 . 38 and 40 and from there the transfer gap 6 be supplied.

The representation in 4 shows the web path of the partial film webs of the transfer film 5 only in the unwinding of the film rolls 27 . 39 and 28 separated from each other. This is due to the fact that the web paths in the supply line to the web tension units 37 . 38 and 40 and to the transfer gap 6 Cover, since the Teilfolienbahnen then lie in the view shown one behind the other.

However, since the web paths of the partial film webs do not overlap, they can also lie side by side directly in the three web tension units 37 . 38 and 40 passed and then the transfer gap 6 be supplied. Each film web is thereby only one of the web tension units 37 . 38 and 40 forwarded and there process-led. From the transfer gap 6 from the film webs are then for winding corresponding film rolls 30 . 41 on the axis 35 and a roll of film 31 on the axis 36 fed.

When using a guide roller 42 all partial film webs of the transfer film 5 jointly led by this and the web tension units 37 . 38 and 40 fed at the same speed. The partial film webs are therefore only in the respective web tension unit 37 . 38 or 40 run separately and can be checked only there in terms of a web break. For this purpose, one of the respective web tension unit 37 . 38 and 40 associated guide roller for checking the Teilfolienbahn be provided on web tear.

In 4.1 is the embodiment according to 4 by additional web tension units 37.1 . 38.1 and 40.1 added in the area of film removal. Thus, each of the discharged Teilfolienbahnen of the film rolls 27 . 28 . 39 even after the transfer gap 6 and before winding on the film rolls 30 . 31 . 41 additionally be adapted in their web tension. This is especially at a timing of the film feed advantage.

So can easily be in a compact arrangement a multi-lane Foil coating with a web tension control for each of the processing traces are done.

Alone 2 to 4.1 shown web tension units 24 . 24.1 . 37 . 37.1 . 38 . 38.1 . 40 and 40.1 range across the entire width of the facility. Thus, any arrangement and width of the film webs or partial film webs during cold foil transfer is possible. The web guide can therefore be chosen completely variable with respect to the position and width of the sub-film webs and their arrangement with respect to the position of the processing tracks on the substrate.

It So in the described device according to the the processing sheet required to be coated with a format-wide film roll or several narrower ones Film rolls are worked over the format width. The Processing can be clocked or unclocked.

By the arrangement of the roll holders on sliding recordings may preferably a so-called parent roll (full-size film roll) axially slidably similar to a side register in web guides be carried out by web presses. This lateral Displacement of the film rolls takes place opposite the subject on the substrate and serves to align the edges of the film the substrate. It can be done without manual intervention and when closed Protecting done.

In order to is an automatic side registers of the film rolls or the Edge of the film rolls to the print subject when setting up in the production run for a full-size film roll or for one or more narrower single roles possible.

A partially automated registering can be done by visually checking the location of the film web 5 for setting up or correction in the continuous printing with shifting of the film web 5 or roll of film via a control panel or the control room done. The corresponding fully automatic control of circumferential or side register with associated lateral roll alignment takes place, for example, in connection with inspection systems which detect a misplacement of elements and can correct the misalignment from the measured values. This is the location of the film web 5 the Drucksujet of the adhesive or a subsequent print image or the position of the film web 5 captured and processed to one of the working cylinders.

In Connection with a film tear detection can prevent Machine damage to the film transfer module a film cap device if necessary with foil catcher near the unwinding reel be assigned. The film break detection is done from the web tension detection or control and / or a sensor for web monitoring.

In 5 is an arrangement for film recording in partial film rolls in a receiving unit 26 in the coating plant 2 shown in plan view. These are recording axes 60 . 61 . 62 . 63 for partial film rolls 27 . 27.1 . 28 . 39 (Reference numeral see 4 ) intended. The recording axes 60 . 61 . 62 . 63 are each designed as self-supporting, one-sided mounted axle stubs.

The holders of the receiving axes 60 . 61 are each on a side wall of the receiving unit 26 provided and there in guides 70 . 71 slidably supported on the side wall. The displaceability may be provided in different directions in the plane of the side wall. The holders of the receiving axes 62 . 63 are each in the free area between the side walls of the receiving unit 26 provided and there in parallel to the receiving axes 62 . 63 guided tours 72 . 73 slidably supported.

The stub axles of the receiving axles 60 . 61 . 62 . 63 can be interchangeable to accommodate partial film rolls of different widths. Furthermore, so recording axes 60 . 61 . 62 . 63 different design, such as friction waves or mandrels are recorded. In addition, so at least the recording axes 60 . 61 be combined with appropriate positioning to a continuous recording axis.

Of the partial film rolls, 27 . 27.1 . 28 and 39 become foil webs 5.1 to 5.4 deducted and to their own web tension unit 64 to 66 directed.

There is every foil web 5.1 to 5.4 passed in a loop around an adjustable dancer roller to compensate for web tension differences individually. The partial film web 5.1 goes through the web tension unit 64 and partial film webs 5.2 respectively. 5.3 respectively. 5.4 go through the web tension units 65 respectively. 66 respectively. 67 , The film rolls can by means of a hoist 50 into the recording waves 60 to 63 be used.

The drive of the recording waves 60 to 63 done by a drive unit 80 out. The indicated drive paths are merely intended to show that for each of the recording waves 60 to 63 a separate drive is provided.

The drive guidance takes place in either direct coupling between take-up shaft and motor. Or the drive is from the outside on the respective leadership 70 to 73 passed through a gear inside the holder to the recording shaft.

• A. Jede Aufnahmewelle 60 bis 63 wird von einem eigenen regelbaren Motor aus angetrieben, um die Abrollgeschwindigkeit individuell einzustellen.
• B. Alle oder wenigstens je zwei der Aufnahmewellen 60 bis 63 werden gemeinsam oder paarweise von einem Motor angetrieben. Dann sind die Aufnahmewellen 60 bis 63 als so genannte Friktionswellen ausgebildet, um Geschwindigkeitsunterschiede beim Abrollen auszugleichen. In Friktionswellen ist die äußere Aufnahme für die Folienrollen (kann formschlüssig sein) gegenüber einer inneren Welle verdrehbar. Zwischen äußerer Aufnahme und Welle ist eine einstellbare Reibverbindung angeordnet.
• C. Alle Aufnahmewellen 60 bis 63 werden gemeinsam von einem Motor angetrieben. Dann können im Antriebsstrang vom Motor zu den Aufnahmewellen 60 bis 63 Schlupfelemente vorgesehen sein, um Geschwindigkeitsunter schiede zwischen den Aufnahmewellen beim Abrollen auszugleichen.
• D. Alle oder wenigstens je zwei der Aufnahmewellen 60 bis 63 werden seitenweise bzgl. der Halterung am Aufnahmemodul 26 gemeinsam von einem Motor angetrieben. Die Aufnahmewellen 60 bis 63 können als Friktionswellen ausgebildet sein oder mittels Schlupfkupplungen angetrieben werden.

There are various drive options to compensate for the speed differences of the partial film rolls occurring during production.

• A. Each recording wave 60 to 63 is powered by its own adjustable motor to adjust the unwinding speed individually.
• B. All or at least two of the recording waves 60 to 63 are driven jointly or in pairs by a motor. Then the recording waves 60 to 63 designed as so-called friction waves to compensate for speed differences during unrolling. In friction waves, the outer receptacle for the film rolls (can be form-fitting) with respect to an inner shaft rotatable. Between outer receptacle and shaft an adjustable friction connection is arranged.
• C. All recording waves 60 to 63 are driven together by a motor. Then in the drivetrain from the engine to the intake shafts 60 to 63 Slip elements may be provided to compensate for speed differences between the recording waves when rolling.
• D. All or at least two of the recording waves 60 to 63 page by page with respect. The holder on the receiving module 26 driven jointly by a motor. The recording waves 60 to 63 can be designed as friction waves or driven by slip clutches.

The formation of slip clutches in the drive of the axles for the film rolls allows the use of a respective film or partial film roll on each one of the slip clutch associated recording shaft 60 . 61 . 62 . 63 , For friction waves, multiple partial film rolls could be used per shaft. However, this is not provided according to the invention, since the handling of the roller exchange would thereby deteriorate.

Both friction shafts and slip clutches in the drivetrain to the take-up shafts 60 to 63 serve to compensate for differences in speed when rolling between the sub-film rolls. The recording waves 60 to 63 be from the common drive 80 driven slower than the film webs are actually deducted. This is constantly a slip motion in the drive 80 or in the friction shaft.

This slip movement is uniform in the inventive solution, since for each of the recording waves 60 to 63 only a partial film roll is provided. Therefore, as a take-up shaft can also be used in mandrel.

The arrangement can of course also in a receiving module 29 be provided for the winding of the used partial film webs.

Furthermore, the brackets of the up shaft 62 and 63 be combined with each other. For this purpose, the brackets are designed as support arms with drive means, in which a receiving shaft can be inserted. Thus, the film roll can be equipped with the pick-up shaft outside the machine and after automatic positioning of the support arms (see Guides 72 . 73 ) to be inserted only in the drive means of the support arms.

The Operation especially during loading is therefore very ergonomic. On the one hand Shafts are combinable, furthermore, the brackets can be freely positioned, each take-up shaft can be individually loaded, the partial film rolls can be exchanged completely flexibly and there is a very flexible drive configuration, the most to the needs of the leadership the film webs in different qualities, widths and thicknesses is tunable.

Furthermore, according to an example 2.1 a roll pad 52 as an insertion aid for fresh film rolls 20 or a roll support 53 as a removal aid for used film rolls 21 intended. The design is preferred for full-size film rolls 20 . 21 suitable over the full working width of the film module 19 Rewind the roll pads 52 . 53 are as rails with locking contours for axes of the film rolls 20 . 21 executed. The role pads 52 . 53 are in pairs end face to the film module 19 in the lateral end of the axles 22 . 23 arranged for the role recording. For loading, the roller supports 52 . 53 frontally to the film module 19 moved, so with respect to the axes 22 . 23 from the foil module 19 pulled out or in the film module 19 be pushed into it.

To change a used film roll 20 becomes its axis 22 from the foil module 19 taken. Then, a new roll of film 20 by depositing by means of a transport axle on the roller support 52 in front of the foil module 19 be dropped off; be discontinued; be deducted; be dismissed. When the roller pads 52 are longitudinally displaceable, the film roll 20 directly by means of the roller support 52 into the foil module 19 inserted. Otherwise, the film roll becomes 20 over the roll support 52 to the axis 22 into the foil module 19 advanced and there with the axis 22 for holding the fresh transfer foil 5 connected.

Furthermore, a spent film roll 21 by separation from the axis 23 for holding the used transfer foil 5 for storage by means of a transport axle on the roller support 52 in the foil module 19 deposited and over the roll support 53 or by means of the roll support 52 by pulling out of the foil module 19 be lifted out. Thereafter, a new empty axis for receiving further used transfer film 5 in the foil module 19 be attached and the film module 19 is ready for use again.
