Description

  The present invention relates to a method and apparatus for depositing a cold film material onto a sheet material in a processing machine as described in the independent claims. The method and apparatus can preferably be introduced into a printing press or varnishing machine for sheet materials and is based on the principle of cold film transfer.

In order to create a metal layer on a printed sheet (sheet material) using a cold film transfer method, several methods and apparatus of this embodiment are known.
A method and apparatus of the same aspect is known from US Pat. No. 6,057,056, which describes a cold film material and a printing apparatus using this material. Here, a sheet material processing machine including a paper feeding device and a paper discharging device is shown, and a plurality of printing devices and one coating device are arranged between the paper feeding device and the paper discharging device. In at least one of these printing apparatuses, the adhesive pattern is applied using a lithographic printing method. The adhesive pattern is applied by a cold press method, and has a specific image providing pattern. A film guide is provided in one coating apparatus having an impression cylinder and a transfer cylinder following the printing apparatus. The film guide is such that the cold film material is guided from one roll into the printing gap of the coating device functioning as a press gap between the impression cylinder and the transfer cylinder, and the remaining cold film material is coated It is designed to be rewound on the discharge side after leaving the device.

  The cold film material includes a film base layer, a release layer fixed on the film base layer, and a film layer bonded to the release layer and facing the sheet material. The film layer can be preferably composed of a plurality of metal layers such as aluminum. The release layer is provided between the metal film layer and the film base layer so that the film layer can be peeled off from the film base layer, particularly in the region of the adhesive pattern for providing a drawing line. It has become. As the sheet material is transported in the printing device, an adhesive pattern is applied to each sheet material. The sheet material is then guided through the coating apparatus, where the metal film layer is brought into contact with the sheet material on the impression cylinder using a transfer cylinder. At this time, the metal film layer facing downward (facing the sheet material) is brought into firm contact with the area of the sheet material to which the adhesive has been applied. When the sheet material is further conveyed, the metal film layer adheres to the sheet material only in the area where the adhesive is applied. The non-image area of the film base layer, release layer, and metal film layer is again wound on a roll as the remaining cold film material. The image-providing area of the metal film layer (image-providing pattern) is firmly adhered to the sheet material in the area of the adhesive pattern. The sheet material is discharged in a coated state.

  In Patent Document 2 published after Patent Document 1, a step of applying a curable varnish layer on a printed material, a step of pressing a film surface against a varnish layer that is still wet, while the film is pressed against the varnish layer A step of applying a transparent coating comprising: curing the varnish layer; and peeling the film from the varnish layer after the varnish layer is cured. A machine configuration for this is disclosed, which includes a pre-printed or coating unit for transferring a curable varnish layer to a substrate and a film surface that is still moistened. A printing unit or coating unit is included after the unit for pressing against the varnish layer. The mechanical configuration further includes a curing unit for curing the varnish layer while the film is pressed against the varnish layer or substrate, and a substrate transport system for the coated substrate and film. The substrate transport system peels the film from the varnish layer after the varnish is cured. The film pressed against the varnish layer is adhered to the varnish layer by the adhesiveness or adhesive force of the varnish, and additionally, the varnish layer of the film on the substrate by the guide roller (36a) disposed downstream. Pushing to is realized. After passing through the guide roller (guide roller 36a), the film (not used) is peeled from the substrate.

  It is an object of the present invention to improve the method and apparatus of the embodiment as described above so that the quality of the film coating on the sheet material is improved.

  This problem is solved by the structural features described in claims 1 and 2. Developments can be understood from the dependent claims.

  The first advantage is that the adhesive is first applied to each side (upper or lower surface) of the sheet material to which the cold film material is to be applied, as shown in the drawing. The adhesive here refers to a strong adhesion means that acts on the boundary surface based on the adhesive force and is cured or dried by the action of irradiation or drying. Moreover, printing ink or varnish including colorless or colored varnish can be used as an adhesive.

  In the following description, an adhesive is arranged on the upper surface of the sheet material as indicated by the line. Thereafter, the sheet material having the adhesive disposed on the upper surface in accordance with the image line is fed into the press gap in the transport direction. Cold film material is also fed into the press gap, and a site-specific force is created in the press gap against the top surface of the cold film material and the adhesive-attached sheet material. It is. This site-specific force is the pressing pressure, and this site-specific force acts on the cold film material and the sheet material (with adhesive) only in this press gap. Due to the site-specific forces and the adhesive arranged according to the line, a strong bond (adhesive force) occurs between the cold film material and the sheet material in this press gap. At this time, the adhesive is not yet cured or completely dried in the press gap, but in one method, the curing or drying process can already be started here.

Next, after passing through the press gap, the sheet material to which the adhesive and the adhered cold film material are attached is closely aligned at the contact angle α in the conveying direction on the impression cylinder that guides the sheet material. It is conveyed to.
While the sheet material carrying the adhesive and the adhered cold film material passes through the contact angle α in the transport direction, no additional force is applied to the sheet material guided on the impression cylinder. This is because the necessary connection has already been made in the pre-press gap with the force specific to the part. As already mentioned, the cold film material is deposited on the sheet material in the press gap, and following the press gap, the sheet material (with adhesive and cold film material attached) is placed on the impression cylinder. It is only placed and guided in the transport direction. At this time, the sheet material (attached with the adhesive and the cold film material) is guided in the transport direction with the front edge fixed to the sheet holding means of the impression cylinder. As a result, the cold film material already deposited on the sheet material in the press gap is conveyed on the impression cylinder in the conveying direction in synchronism with (in close contact with) the sheet material.

  In addition, the sheet material (attached with adhesive and cold film material) is preferably irradiated or irradiated at or after passing through the press gap in the conveying direction. Drying is performed. This irradiation or drying action preferably occurs immediately after leaving the press gap. At this time, at least the adhesive disposed on the sheet material according to the pattern is irradiated or dried so that the curing process or the drying process starts at least, that is, the curing process or the drying process operates. Is done.

In the preferred method, immediately after passing the contact angle α, the sheet material (attached with adhesive and cold film material) is further conveyed in the conveying direction as follows.
In the discharge gap following the contact angle α, preferably the non-image-providing film layer and release layer and film base layer of the metal film layer are peeled away from the sheet material as unnecessary residual cold film material. The film base layer is firmly bonded to the release layer and the non-image-providing film layer. Preferably, the image-providing film layer of the metal cold film material is peeled off from the film layer of the cold film material thanks to an adhesive which is arranged pictorially on the sheet material and which has at least started the curing or drying process. Due to the adhesive force of the adhesive, it remains attached on the sheet material that is further guided in the conveying direction on the impression cylinder.

Since the sheet material (attached with adhesive and cold film material) is no longer pressed in the region of the contact angle α, the sheet that is guided over the impression cylinder, for example a pressing cylinder, a guide cylinder or a turning cylinder There is no need for a means to press the cold film material against the paper material. There is a discharge gap following the region of the contact angle α in the transport direction, in which the cold film material is
-First, the film-providing film material portion of the cold film material that is adhered onto the sheet material by an adhesive;
-Secondly, the unused film material part of the cold film material (film base layer, release layer, film layer that is not provided with image line),
Separated.

  Behind this discharge gap in the transport direction, a direction changing means for carrying away unused film material portions (cold film material film base layer, release layer, non-image-providing film layer) is preferably provided on the frame. It is fixed and arranged. This direction changing means is only for guiding the cold film material to be carried away in a web-like manner and does not contact the impression cylinder for guiding the sheet material.

The second advantage is that in this method, during the curing / drying process (in the region of the contact angle α), the sheet material and the combined cold film material are closely aligned and synchronized. Then, after being guided over the impression cylinder guiding the sheet, and after the press gap, the sheet material (attached with adhesive and cold film material) is added by the pressing means This means that a pressing force cannot be applied. This may, for example, cause the sheet material and the cold film material to shift (if the curing / drying process has not yet been fully completed), wrinkles or folds, The possibility of generating microcracks in the material can be avoided. As a result, the quality of the film coating of the sheet material is improved.
In addition, the image providing film layer desirably peels better from the metal film layer. As a result, the edge of the image-providing film layer on the sheet material is sharpened, the brightness is increased, or the matte effect is improved, so that the quality of the film coating can also be enhanced tangibly here. .

  The third advantage is that in addition to the operating method steps described above, after the adhesive is applied to the sheet material, it passes through the press gap where the cold film material adheres to the sheet material. The adhesive has already been dried or cured before passing through the press gap, or at least the drying or curing has been activated, since the adhesive has already been irradiated or otherwise dried. That is. It should be noted that the adhesive present on the sheet material during passage through the press gap still has sufficient adhesion to bond to the cold film material or the image-providing film layer (at the press gap). It is to have.

  Alternatively or additionally, the sheet material with the image-providing adhesive and the attached image-providing film layer conveyed over the impression cylinder after passing through the discharge gap is again irradiated, especially UV Irradiation or drying can be performed. To that end, the irradiation source / drying source can be spaced from the impression cylinder guiding the sheet material (adhesive and cold film material attached) or in the paper delivery device. it can.

  A fourth advantage is that the adhesion of the cold film material to the sheet material can be realized in a separate film transfer device. In a preferred embodiment, such a film transfer device comprises one module having at least one impression cylinder for guiding the sheet material, an additional cylinder for guiding the cold film material, and an irradiation source / drying source. can do. The film transfer device can preferably be incorporated and arranged in a processing machine having at least one, preferably a plurality of printing devices and / or coating units.

In a preferred configuration, at least one or preferably a plurality of printing devices and / or coating units can be placed in front of or behind the film transfer device in the transport direction of the sheet material.
In a desired configuration, the film transfer device can be composed of components of a printing device or a coating unit. For example, the film transfer device can consist of an in-line printing device or coating unit known in the printing press configuration, known as a three cylinder system in the case of a printing device. Preferably, the impression cylinder is a double diameter or multiple multiple diameters (1/2 rotation or 1/3 rotation, etc .: sheet paper) with respect to a further single diameter cylinder (one rotation cylinder: one sheet is conveyed by one rotation). One sheet is conveyed by 1/2 rotation or 1/3 rotation). At this time, the “7 o'clock cylinder arrangement” in the film transfer apparatus of the impression cylinder and the additional cylinder can be realized in the same manner as the printing apparatus / coating unit.

  The application of the adhesive to the sheet material in line with the image line portion can be performed in a printing apparatus or a coating unit placed in front of the film transfer apparatus in the sheet material conveyance direction. Alternatively, a dressing device for adhesive application can be placed in the printing device / coating unit as an auxiliary device.

  The film transfer device can be disposed in any position of the machine in the processing machine. Thereby, in the case of a printing press with a plurality of printing devices, the image-providing cold film coating or metallization layer can be applied before or after the ink layer or varnish layer is applied. It can be carried out between application of the ink layer or varnish layer, or after application of the ink layer or varnish layer. As the cold film material, a decorative film or a functional film, particularly a metal cold film material can be preferably used.

  A fifth advantage is that the processing machine is not limited to one individual film transfer device. Since the described film transfer apparatus can be arranged in a plurality in a single sheet material processing machine, various image line providing film layers in one pattern can be deposited on the sheet material one after another. At this time, the first image providing film layer is attached to the first adhesive pattern previously applied in the first film transfer device, and is then overlapped with the first adhesive agent pattern. It is possible to apply a further adhesive pattern that conjugates or complements the pattern and to apply a second image-providing film layer.

The sheet material can be composed of any kind of substrate, especially paper, cardboard, cardboard, (plastic) film. The cold film material that can be used can be arranged per zone of the sheet material or across the format width of the sheet material. Similarly, a plurality of partial rolls can be arranged for each zone of sheet material or across the format width of the sheet material.
Supplementally, if necessary for the film transfer device, for example one additional processing unit for embossing, cutting or punching, or a coating unit for surface finishing of sheet material (eg gloss / matte effect), Alternatively, at least one printing device or one imprinting device for color printing can be placed behind.

The pressing cylinder 2 and the cylinder 1 form a press gap 10. Through this press gap 10, the cold film 7; 7.1-7.4 and the sheet material 6 (with the adhesive 12 attached) can be conveyed. In the press gap 10, by applying a force, the film layers 7.3 and 7.4 of the cold film material 7; 7.1, 7.2, 7.3, and 7.4 are made to conform to the image area. Can be pressed against the sheet material 6 to which the adhesive 12 is applied.
It is the press gap that has means for generating the site-specific forces acting on the sheet material 6 and the cold film material 7; 7.1, 7.2, 7.3, 7.4. Only the impression cylinder 2 and the cylinder 1 forming 10.
Using the pressing force achievable by the cylinder 1, the cold film material 7; 7.1, 7.2, 7.3, 7.4, in particular the film layers 7.3, 7.4, It is possible to apply the adhesive 12 arranged in conformity to the attached sheet material 6. Following the press gap 10, the cold film material 7; 7.1 to 7.4 and the sheet material 6 guided by the impression cylinder 2 are closely aligned at the contact angle α and conveyed over the impression cylinder 2. It can be conveyed in synchronism with direction 3. At this time, the sheet material 6 is placed on the outer surface of the impression cylinder 2, and the sheet material 6 is provided with an adhesive 12 arranged in accordance with the image line portion. At this time, the cold film material 7; 7.1 to 7.4 is in contact with at least the adhesive 12 arranged in line with the image area.
In the region of the contact angle α, the first irradiation source / drying source 8 for the adhesive 12 is arranged adjacent to and spaced from the impression cylinder 2. A discharge gap 11 is arranged behind the contact angle α in the transport direction 3, and the cold film material 7; 7.1 to 7.4 is

At this time, the direction changing means 15 is not in contact with the impression cylinder 2 guiding the sheet material 6 to which the image providing film layer 7.4 is attached.

The cold film material 7; 7.1 to 7.4 can make the press gap 10 transportable in the transport direction 3 according to the format of the sheet material 6. Alternatively, the cold film material 7; 7.1 to 7.4 can make the press gap 10 transportable in the transport direction 3 depending on the picture.
While passing through the body groove 4, the cold film material 7; 7.1 to 7.4 can be stopped from being conveyed through the press gap 10. That is, during the passage of the body groove 4, the conveyance (pre-feed) of the cold film material 7; 7.1 to 7.4 can be temporarily interrupted.
Alternatively, while passing through the body groove 4, the cold film material 7; 7.1-7.4 can be transported through the press gap 10 in the direction of the film stock roll 13. That is, the cold film material 7; 7.1 to 7.4 is temporarily “reversely fed” in the direction of the film stock roll 13 in the direction opposite to its original transport direction. By such an operation method, the material consumption of the cold film material 7; 7.1 to 7.4 can be reduced.

The operating method is as follows: In order to adhere the cold film material 7 to the sheet material 6 in the processing machine, it is applied to the image area of the adhesive 12 in the attaching device (printing device C or coating unit A). A suitable coating is realized on the sheet material 6. A pressing gap 10 is formed by the impression cylinder 2 that guides the sheet material 6 using the holding means 5 and the further cylinder 1 adjacent thereto, and the cold film material 7 guides the pressing gap 10. The cold film material 7 is bonded to at least one film base layer 7.1, one release layer 7.2 fixed on the film base layer 7.1, and the release layer 7.2. 6 is composed of film layers 7.3; 7.4 assigned to 6. By applying a force in the press gap 10, the film layer 7 is pressed against the sheet material 6 to which the adhesive 12 is applied in line with the image area.
The site-specific forces are applied to the sheet material 6 and the cold film material 7; 7.1, 7.2, 7.3, 7.4, and strong bonding occurs by the adhesive 12 in the press gap 10 Only. The strong bond occurs due to the adhesive force at the interface between the adhesive 12 and the sheet material 6 or between the adhesive 12 and the film layers 7.3, 7.4.
Following the press gap 10, the cold film material 7; 7.1 to 7.4, and the sheet material 6 that is coated with the adhesive 12 in line with the image area and guided on the impression cylinder 2 are provided. The impression cylinder 2 is transported in the transport direction 3 with a close contact at the contact angle α. At this time, since the adhesive 12 is irradiated or dried at the contact angle α (first irradiation source / drying source 8), at least the process of curing or drying the adhesive 12 on the sheet material 6 is started. And a strong bond between the sheet material 6 and the adhesive 12 in line with the image area, and the adhesive 12 and the film layers 7.3, 7.4 (in the press gap 10). A strong bond between the part in contact with the adhesive 12 occurs. Thereafter, after passing through the contact angle α in the transport direction 3, the cold film material 7; 7.1 to 7.4 is
-Separated into a film base layer 7.1, a release layer 7.2, a non-image-providing film layer 7.3 of the film layer, and the remaining cold film material 7.1-7.3 is delivered,
-Adhesive 12 arranged in line with the image area and the sheet material 6 attached with the image layer providing film layer 7.4 of the film layer are further conveyed in the conveyance direction 3 .

  In a further configuration, the second radiation source / drying is applied to the sheet material 6 that has been fed in with the adhesive 12 in line with the image area before the press gap in the conveying direction 3. Source 9 can be activated. Thereby, the curing or drying process of the adhesive 12 (on the sheet material 6) can already be started before passing through the press gap 10.

  In a further configuration, behind the discharge gap 11 in the transport direction 3, the adhesive 12 and the image-providing film layer 7.4 (the remaining cold film material 7.1 to 7.3 is already on the film collecting roll 14. The second irradiation source / drying source 9 can act on the adhesive 12 and the adhesive 12 can be further cured or finally dried.

  In a plurality of examples for carrying out the cold film conveyance shown here, the film stock roll 13 is assigned to each film transfer device B on the sheet supply side. The film stock roll 13 can be provided with a rotational drive device. The rotational drive is required to feed the cold film material 7 to the film transfer device B, preferably in a continuously controlled manner, and is therefore controllable. On the discharge side of the film transfer apparatus B, the used (remaining) cold film material 7.1 to 7.3 is wound on the film collection roll 14. Again, a controllable drive can be provided.

  Furthermore, a tension roller (not shown) can be provided in the area of the web guide of the cold film material 7. With such a tension roller, the cold film material can always be held with the same tension with respect to the cylinder 1.

A plastic cover corresponding to a rubber blanket or a printing blanket is preferably attached to the surface of the cylinder 1. The plastic cover has a predetermined elasticity. The surface of the plastic cover can be constructed relatively flat or structured, for example using a glass pearl blanket, and has little adhesion to the cold film material 7. Alternatively, the plastic cover can be a relief printing plate or a perforated rubber blanket. By providing a plastic surface, it becomes possible to transfer the image providing film layer 7.4 onto the sheet material 6 with a cleaner and sharper edge. Furthermore, a relatively wide press gap 10 is created by the elastic structure of the plastic cover. Furthermore, for example, the press gap 10 can be further increased by doubling the diameter of the impression cylinder 2 with respect to the single-diameter cylinder 1. By all these techniques, on the one hand, the surface in the press gap 10 is made relatively large, and on the other hand, the surface of the cylinder 1 pressing the cold film material 7 and the impression cylinder 2 are guided. It is possible to ensure mobility between the sheet material 6 (with the adhesive 12). By these means, a very fine pattern of the image providing film layer 7.4 is reliably transferred onto the sheet material 6.
The hardening / drying of the adhesive 12 starts at least after passing through the press gap 10, and in addition to the action of the force in the press gap 10, with the enhanced adhesion action, the image providing film layer 7.4 and Due to the improved strong bond between the adhesive 12 on the sheet material 6, the remaining cold film material 7.1 to 7.3 that can be fed to the film collecting roll 14 in the subsequent discharge gap 11. Therefore, it is possible to achieve better peeling (stripping) of the image line providing film layer 7.4 with a sharper edge.

  The cold film material 7 (7.1-7.4) can guide the press gap 10 in a timing control operation. For this purpose, means for temporarily accommodating the cold film material 7 (timing control operation) can be provided before and / or after the press gap 10 in the conveying direction of the cold film material 7. This makes it possible to save the cold film material 7 while saving it.

  The arrangement of the film stock roll 13 and the film collection roll 14 is not limited to the above-described configuration. Also, such a film stock roll 13 can desirably be disposed on a component of a processing machine adjacent to the film transfer apparatus B. Alternatively, such a film stock roll 13 can also be assigned in a separate, separate machine of the processing machine or placed in a printing hole, in which case the cold film material 7 is there To the film transfer device B. Similarly, the film collection roll 14 can be disposed on a component of the processing machine adjacent to the film transfer apparatus B. In a further configuration, the film collection roll 14 may not be included. In that configuration, the cold film material comprising the film base layer 7.1, the release layer 7.2, and the non-image-providing film layer 7.3 peeled and discharged in the discharge gap 11 can be sent to the shredder apparatus. . At this time, supply / discharge of the cold film material 7 can be supported by the guide means.

  Application of the adhesive 12 to the sheet material 6 can be temporarily interrupted in order to perform a setup process or a cleaning process. Further, at least the impression cylinder 2 of the film transfer apparatus B can be rotated by a driving device while the cold film material 7; 7.1 to 7.4 is desirably stationary in the cylinder 1 which is separated from the impression cylinder 2. can do.
