Abstract

In order to transfer an image coating from a carrier film to a printed sheet, an adhesive image layer is applied to the printed sheet. The carrier film comprising the image coating is then guided past the printed sheet while being pressed thereagainst in a film transfer module (2) such that the coating adheres at the joints and an image is generated. In order to improve the function, simplify the device, and increase flexibility, a holder for reels of the transfer film (5) is provided for easier handling.

Description

MAN Roland Druckmaschinen AG

Modular film unit

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

It is known to produce metallic layers on printed sheets by means of a film transfer process. Thus, EP 0 569 520 B1 describes a printing material and a printing device using this material. In this case, a sheet-processing machine is shown, which has a feeder and a boom, wherein printing units and a film transfer module are arranged between the two units. 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. This is designed in such a way that a film strip or a transfer film is guided through the transfer nip of the film transfer module between the impression cylinder and the transfer cylinder by a film supply roll. The film strip is rewound on the exit side after leaving the film transfer module. The transfer film has a carrier layer on which imaging layers such as metallic layers, for example of aluminum, can be applied. When printing sheets are transported through the printing unit, each sheet is given an adhesive pattern. Thereafter, the sheet is passed through the film transfer module, wherein by means of the transfer cylinder, the resting on the impression cylinder sheet is brought into contact with the film material. In this case, the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet. After the further transport of the printed sheet, the metallic layer adheres only in the area of the pattern provided with the adhesive. The carrier film thus becomes the metallic layer

11.12.2008 taken in the field of adhesive pattern. The used in this way transfer film is wound up again. The print sheet is laid out in the coated state.

It is known to use 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 of transfer film is expensive.

The object of the invention is therefore to provide a device by means of which the transfer of an imaging layer, e.g. a metallization can be done safely, economically and accurately, the device should be easy to handle.

The solution to this problem results in a device according to the features of claim 1.

Advantageously, a method is used to guide the transfer film, in which the film web is stored on one or more film rolls and can be used for changing film rolls by means of an adhesive device within the same recording an existing film roll used.

In devices according to the invention, recordings for film rolls are provided in two variants, which permit easy replacement of one or more film rolls.

In a first variant, the receptacles can be provided in a module, wherein at least two axes for receiving film rolls are arranged one above the other. One or more film rolls can be mounted on each axis. The or the axes can be assigned drives. Each holder of a film roll may be associated with a web tension unit. In this way, an improvement in set-up times is achieved in conjunction with a film transfer module.

11.12.2008 In a second variant, the receptacles can be provided in two modules, wherein in each module at least two axes for receiving film rolls are arranged one above the other. One or more film rolls can be mounted on each axis. The or the axes can be assigned drives. At least in one module, one or each support of film rolls may be associated with a web tension unit. In this way, a further improvement of set-up times in connection with a film transfer module is achieved by greatly simplifying the replacement of film rolls.

In the following the invention is illustrated in more detail with reference to figures. Showing:

FIG. 1 shows a basic illustration of a printing press with a film transfer device,

FIG. 2 shows a first module according to the invention for receiving film,

Figure 3 shows a second module according to the invention for film recording and

Figure 4 shows a third module according to the invention for film recording.

FIG. 1 shows a sheet-processing machine, here a printing press, which consists of at least two printing units.

A sheet to be coated is provided in a first step in the applicator 1 with an imaging adhesive pattern. For this purpose, a printing unit of an offset printing press with dyeing and dampening units 11, a printing plate on a plate cylinder 12, a blanket or blanket cylinder 13 and a counter-pressure cylinder 4 can be used.

In the second step, a transfer film 5 is guided under pressure through a transfer nip 6 together with the printing sheet. A film transfer module 2 used for this purpose can be a printing unit, a coating module, a base unit or another processing station of a sheetfed offset printing press.

The transfer nip 6 in the film transfer module 2 is formed by a transfer cylinder 3 and an impression cylinder 4. The transfer cylinder 3 can a

11.12.2008 Blanket or form cylinder of a known offset printing unit or paint module of a sheetfed offset press correspond. Within the film transfer module 2, a web guide for transfer films 5 is shown.

The device can also be arranged as an integrated film transfer module FA within a printing unit.

In the basic illustration according to FIG. 1, a film supply roll 8 is assigned to the film transfer module 2 on the side of the sheet feed. The film supply roll 8 has a rotary drive 7. The rotary drive 7 is required for the continuous controlled feeding of the transfer film 5 to the film transfer module 2 and is therefore controllable. Furthermore, guide devices 14, such as deflection or tensioning rollers, pneumatically actuated conducting means, guide plates or the like, are provided in the area of the film supply and removal. Thus, the film web of the transfer film 5 can always be guided flat without distortions and held in the same voltage with respect to the transfer cylinder 3.

The transfer film 5 can be guided around the transfer cylinder 3, the transfer film 5 advantageously being able to be supplied to and removed from the transfer nip 6 only from one side of the film transfer module 2 (see dashed representation). Furthermore, the transfer film 5 can also be guided essentially tangentially on the transfer cylinder 3 or only in a small circumferential angle in the transfer nip 6. Here, the transfer film 5 is attached to one side of the film transfer module 2 and removed to the opposite side. On the discharge side of the printing unit, a film collecting roller 9 is shown, by means of which used sheet material is wound up. Again, a rotary drive 7 is provided, which is controllable.

In addition, dryer 16 can additionally be arranged in the film transfer module 2 or FA in order to pre-dry the adhesive on the printing substrate and / or to finish drying the finished coating. By means of an inspection device 17, the coating quality can be observed. Finally, in

11.12.2008 the film transfer module 2 or FA cleaning means R be provided to remove from the film web of the transfer film 5 sloping and possibly adhering to the cylinders impurities from the machine.

FIGS. 2, 3 and 4 show devices according to the invention for receiving film rolls.

FIG. 2 shows a device in the embodiment with a single receiving module 19 for film rolls 20, 21, which is placed on the film transfer module 2 or FA. The receiving module 19 is provided with two axes 22, 23 for holding film rolls 20, 21. On each axis 22, 23, one or more film rolls 20, 21 can be supported correspondingly in the direction of transport of the printing sheets to be coated parallel to each other processing tracks. The feeding of the transfer film 5 to the transfer nip 6 is effected by one or more film rolls 20 supported on the lower axis 22 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 nip 6 parallel to the film transfer module 2 or FA up to one or more film rolls 21 held on the upper axis 23.

All axes 22, 23 may be provided for driving or braking the film rolls 20, 21 with rotary actuators.

Below the lower axis 22 or held there of the film rolls 20, a web tension unit 24 is arranged. The web tension unit 24 may be designed as a retractable module. It has a plurality of guide rollers 25, 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 film rolls 20 arranged on the axis 22 corresponding to the processing tracks, a plurality of web tensioning units 24 may also be arranged interchangeably as modules parallel to each other.

11.12.2008 In this arrangement, it is therefore possible to work both with one format width or with several part width film webs.

Furthermore, by way of example according to FIG. 2, a roller support 52 is provided as an insertion aid for fresh film rolls 20 or a roll support 53 as a removal aid for used film rolls 21. The embodiment is preferably suitable for full-format film rolls 20, 21 which extend over the full working width of the film module 19. The roll supports 52, 53 are designed as rails with latching contours for axes of the film rolls 20, 21. The roller supports 52, 53 are arranged in pairs at the end face to the film module 19 in the lateral end region of the axles 22, 23 for the roller receptacle. For loading, the roller supports 52, 53 can be moved on the face side to the film module 19, ie pulled out of the film module 19 relative to the axes 22, 23 or pushed into the film module 19.

To change a used film roll 20 whose axis 22 is removed from the film module 19. Then a new film roll 20 can be deposited by depositing by means of a transport axis on the roller support 52 in front of the film module 19. If the roller supports 52 are longitudinally displaceable, the film roll 20 can be inserted directly into the film module 19 by means of the roller support 52. Otherwise, the film roll 20 is advanced over the roll support 52 to the axis 22 in the film module 19 and there connected to the axis 22 for holding the fresh transfer film 5.

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

11.12.2008 FIG. 3 shows a device with a first receiving module 19 for film rolls 27, 28 according to FIG. 2 and a second receiving module 26 for film rolls 30, 31. The first receiving module 26 is mounted on the film transfer module 2 or FA, and the second receiving module 29 is placed on a downstream printing or processing unit 32 of the sheet-processing machine. Each of the receiving modules 26, 29 is provided with two axes 33, 34 and 35, 36 for holding film rolls 27, 28 and 30, 31 respectively. On each of the axes 33, 34 and 35, 36, one or more film rolls 27, 28 and 30, 31 can be supported according to the processing tracks to be supplied on the sheet to be coated.

All axes 33, 34 and 35, 36 can be provided with rotary actuators for driving or braking the film rolls 27, 28 and 30, 31.

Likewise, more than two axes per module may be arranged to accommodate further film rolls for unwinding or unrolling. This allows a variety of film rolls for a corresponding number of processing traces in the modules record. The following information on film handling also applies to modules with more than two axes for receiving film rolls.

The feeding of the transfer film 5 to the transfer nip 6 takes place from one or more film rolls 27, 28 from the first receiving module 26. In this case, the transfer film 5 can be fed to the transfer nip 6 per processing track either from film rolls 27 held on the lower axis 33 or also from film rolls 28 held on the upper axis 34 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 nip 6 from parallel to the film transfer module 2 or FA to the second receiving module 29 and to the upper and lower axes 35, 36 of the supported film rolls 30, 31.

11.12.2008 In the first receiving module 26, a web tension unit 37 is arranged below the lower axis 33 or the film rolls 27 held there. The web tension unit 37 may be designed as a retractable module. It has a plurality of guide rollers which are adjustable in relation to the path of the web according to the required web tension of the film web. The adjustment can be regulated as a function of the web tension. Depending on the number of corresponding to the required processing traces on the axes 33, 34 arranged film rolls 27, 28 may be arranged in parallel to each other and several web tension units 37 as modules interchangeable.

Furthermore, the upper axle 34 and the film rolls 28 held thereon are assigned one or more responsive web tension units 38.

Also in the last-described arrangement, it is possible to work both with one transfer foils arranged in a format-wide or with a plurality of part-width foil webs or correspondingly required processing tracks.

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

For this purpose, in the receiving module 26 described in FIG. 3, a supply roll 28 for transfer film 5 can already be provided on a free axis 34, while the active film roll 27 is processed. At or shortly before the complete consumption of the transfer film 5, the supply roll 28 can be connected by means of bonding with the active film roll 27 at a standstill. This can be done semi-automatically, manually or with auxiliary means. Thus, the new transfer film from the new film roll 28 can be fed directly into the film transfer module 2 by means of the transfer film currently being processed.

11.12.2008 In conjunction with this, the system described can also be automated. For this purpose, a sufficient amount of transfer film 5 can be stored in a magazine, eg in conjunction with a web tension unit 37 or 38 for the outgoing transfer film 5 from the active film roll 27. Then, bonding between the active film roll 27 and the new roll of film 28 to be taken into use can take place. With appropriate acceleration of the subsequently to be used film roll 28, possibly up to machine speed, the change process between old and new film roll 27 and 28 is reduced so much that a quasi-continuous roll change takes place. This is also a full automation possible, as is common in automatic reel splicers in web-processing printing machines.

The web tension units 37, 38 shown can also be provided in the web running direction after the transfer nip 6 for the take-up side of the film modules. This results in a possibility to carry out the film transport in steps controlled, since on both sides of the coating film film stores are arranged, which can perform a clocking of the film feed.

In this case, the conventional arrangement of the film transfer module remains distributed over two printing towers of the printing press, as shown in Figure 1, obtained. For this reason, the take-up film rolls 30, 31 can also be doubled. 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 interruptions.

Furthermore, the arrangement can be improved by a loading and unloading of the axes 22 and 33, 34 and 23 and 35 and 36 of the receiving modules 19 and 26 and 29 via the end faces, e.g. done from the back of the printing machine ago. In this case, the film rolls on axes designed as mandrel, e.g. deferred in sleeve technology. This can be done by means of the simplest means of transport, e.g. done with pallet truck. If an integrated hoist is available

11.12.2008 the result is an even smaller space requirement from the back of the machine for reel change.

The integrated hoist can be designed as arranged on one or both receiving modules cable on a swivel arm in the manner of a crane.

Advantageously, according to Fig. 2 or 5 in the receiving modules 19, 26, 29 integrated hoists 50, 51 are present. This results in an even smaller space requirement for roll change. The hoists 50, 51 are each arranged on one of the receiving modules 19, 26, 29 of the coating device 2. They are so close to the respective installation location of the film rolls in the receiving modules 19, 26, 29 that a very compact arrangement is created. Therefore, with the hoist 50, the installation of the fresh film rolls 27, 28, 39 on the roll-off side into the receiving module 19 or 26 can take place. Furthermore, the removal of the filled collecting rollers 21 on the roll-up side from the receiving module 19 can also take place by means of the hoisting tool 50 in FIG. 2. Furthermore, by means of the hoist 51 in FIG. 5, the removal of the filled collecting rollers 30, 31, 41 on the roll-up side can take place from the receiving module 29. The hoists 50, 51 are preferably arranged as a flat, rotatable support with a cable on top of the receiving modules 19, 26, 29. The assignment is selected so that the front side of the receiving modules 19, 26, 29 for the installation or removal of film rolls 27, 29, 30, 31, 39, 41 can be reached. This eliminates the need to place additional hoisting equipment next to the machine and improves the placement and handling of the machine.

Here, axles 22 or 33, 34 and 23 or 35 and 36 can be used, the storage is unilateral and thus cantilevered. The lower weights of the narrow film rolls make this possible. For this purpose, the receptacles, which are laterally end-side in each case in the width of the film transfer module 2, 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 axle

11.12.2008 Sen, when their free ends point to each other, are also used together to accommodate format-wide film rolls.

It is also possible to execute the axes in the form of so-called friction waves. This can be over the width of the axis one-piece friction waves or multi-part in the form of Teilfriktionswellen trained axes. Friction shafts have the advantage that the effect of the rotational movement of the film rolls during unwinding or winding of the transfer film 5 by friction action against a rigid axis is performed self-adjusting and thus the web tension is relatively easily maintained.

A device which can be used for this purpose is shown in FIG. 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 FIG. 4, two film rolls 27 and 39 are arranged axially offset next to each other on the axis 33, and a film roll 28 is again arranged axially offset on the axes 34 relative to the two other film rolls 27, 39. The axis 33 may have two roller receptacles or be designed in two parts. The axial position of the film rolls 27, 39 and 28 form determinable processing tracks for the partial film webs of the transfer film 5 in their position and width.

The partial film webs of the film rolls 27, 39 and 28 can be guided via a deflection roller 42 to three web tension units 37, 38 and 40 arranged one above the other and in the receiving module 26 below the roll holders and fed from there to the transfer nip 6.

The illustration in FIG. 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 one another. This is due to the fact that the railway tracks in the area of Zulei-

11.12.2008 tion to the web tension units 37, 38 and 40 and to cover the transfer nip 6, since the sub-film webs are then in the view shown one behind the other.

However, since the web paths of the partial film webs do not overlap, they can also be routed side by side directly into the three web tension units 37, 38 and 40 and then fed to the transfer nip 6. Each film web is thereby fed to only one of the web tension units 37, 38 and 40 and guided there in accordance with the process. From the transfer nip 6, the film webs are then fed onto the axis 35 for winding corresponding film rolls 30, 41 and a film roll 31 on the axis 36.

When using a deflecting roller 42, all partial film webs of the transfer film 5 are jointly guided by this and the web tension units 37, 38 and 40 fed at the same speed. Consequently, the partial film webs are guided separately only in the respective web tension unit 37, 38 or 40 and can only then be tested there for 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.

Thus, a multilayer film coating with a web tension control for each of the processing tracks can be carried out in a simple manner in a compact arrangement.

All of the web tension units 37, 38 and 40 shown in Figures 2, 3 and 4 extend over the entire width of the device. 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.

11.12.2008 To further improve the arrangement is provided to associate the film guide means for detecting the splice in the film web. A corresponding sensor arrangement is arranged between the film unrolling in the receiving module 19 or 26 and the feed of the transfer film 5 to the transfer nip 6 in the film transfer module 2. By means of the recognition of the splice, the sheet or sheets coated with the splice or the area before and after the splice can be recognized and sorted out by means of appropriate aids in the delivery pile of the printing press. For this purpose, the corresponding movement distance of sheets or transfer film can be calculated by means of a computer. Alternatively, the splice can be marked and sensory detected by means of an RFID transponder or a magnetic strip. In this case, it is possible to transfer the marking element to the printed sheets even with several film webs. Then different benefits to the discharge existing on the sheet can be recognized as defective in a further processing station, so that benefits with Folienklebestelle be safely sorted out.

Furthermore, the removal of the used film web after the transfer nip can be done by turning bars, so that it can be led out laterally out of the printing machine. Then, a reel above of the press arranged auxiliary equipment is possible. Likewise, the used film web can be shredded there and vacuumed.

Overall, therefore, can be used in the described device according to the required on the sheet to be coated printing process traces with a format-wide film roll or several narrower film rolls on the format width. The processing can be clocked or untagged.

In conjunction with a film tear detection, a film cap device may be associated with film catcher in the vicinity of the unwinding to the film transfer module to prevent machine damage. The film breaker

11.12.2008 Identification takes place from the web tension detection or control and / or a sensor for web monitoring.

Overall, therefore, the invention also contains the following partly optional features for the film treatment in a transfer module:

a) at least the unwinding side of the film guide is driven by a motor b) receiving only a film roll on a continuous axis, which can be moved for positioning in the axial direction. c) Supporting arms for overhead rolls of film for single roll use d) Mandrels as a replacement set for different film rolls e) Mandrels can be positioned in all directions (in the axial direction and transversely to the axial direction) f) The support of the support arms of the mandrels works together with through drive shafts and into the Supporting arms include gear stages for the drive shafts g) Below the roller mounts are several dancer roller groups h) Dancers are operated pneumatically (rodless cylinders) i) Web tear control per film web over a deflection roller j) On the up and / or unwinding side of the film guide can be by means of a central drive a single or a plurality of parallel friction shafts are driven or it can be provided in each case individual drives for several parallel take-off and / or take-up shafts k) Friction shafts can be made in one piece or for several sub-roles.

I) Friction shafts can be provided in one piece particularly advantageous for axes with one-sided flying mounting m) per take-up reel a pair of flanged wheels for guiding the film web n) running control of the film web through diameter detection by laser sensor or light curtain (also allows run length calculation)

11.12.2008 o) A loading device is assigned to each tower of the take-up and unwinding side, which has manually or motor-operated hoists. p) Single roll with full format is stored on the unwinding side in a movable rail and moved from there into clamping position and locked. q) Control cabinet is integrated on one side on the printing mechanism incl. control cabinet cooling, ie there is no separate space requirement r) Up and unwinding side are covered by remote-controlled shutters (secured) s) Single roll in full format is axially displaceable (similar to side register) without manual interventions and at closed shooters t) automatic side registering of the film roll (edge) to the print subject when setting up in the print run for a full size single roll or partial rolls) u) semi-automated registering by visual control to set up or
