Abstract
Description
[0001] The invention relates to a method for applying an adhesive film section separated from a strip-shaped adhesive film to a book cover and to a device for carrying out the method.
[0002] A book-like document, in particular a security and / or valuable document such as a passport, comprises a book cover. On the inside of the book cover there is an endpaper which is attached to the book cover. This endpaper can be connected to several other data pages or inner pages via a seam to form a book block. Such a book cover consists of a book case which can have a decorative wrapping on its outside. To attach the endpaper to the book case, an adhesive film must be applied beforehand. This adhesive film is currently cut and applied by hand. This has the disadvantage that production is time-consuming and the application of the adhesive film to the inside of the book case can be inaccurate.
[0003] DE 32 36 702 C2 discloses a device for applying an adhesive strip to an object. One end of the adhesive strip is gripped by a gripper in a clamping and cutting station. The gripper is then moved along the object, with the adhesive strip still held by the gripper in a final position. Subsequently, several stamps are pivoted toward the object to be bonded, with the adhesive strip interposed, so that the adhesive strip is pressed onto the object and simultaneously severed by cutting knives.
[0004] The invention is based on the object of providing a method for applying a strip-shaped adhesive film to a book cover and a device for applying a strip-shaped adhesive film to the book cover, by means of which the cycle time is reduced and an increased processing accuracy is achieved.
[0005] This object is achieved by a method for applying an adhesive film section separated from a strip-shaped adhesive film to a book cover, in which a book cover is placed and aligned on a pressing surface of a matrix of a pressing device in a device for applying the adhesive film section from the strip-shaped adhesive film to the book cover, in which a gripping device is assigned to a pressing surface in a starting position in a gripping station and the gripping device grips an adhesive film section, in which the adhesive film section is transferred with the gripping device to a pressing stamp of the pressing device arranged adjacent thereto, in which after the transfer of the adhesive film section to the pressing stamp, the adhesive film section is detached from the gripping device and the gripping device is returned to the starting position in the gripping station and a new,in the gripping station, the adhesive film section is gripped by the gripping device, in which the first and further adhesive film sections are separated by a cutting device, in which the pressure stamp and the contact surface of the pressure device are brought together and the adhesive film section is applied and glued to the book cover, and in which, after the adhesive film section has been glued to the book cover, the pressure stamp and the contact surface are moved apart and the pre-laminated book cover is removed.
[0006] This process applies and adheres a strip of adhesive film to a book cover within a precisely specified cycle time. By positioning the adhesive film section relative to the pressing die of the pressing device and aligning the book cover on the pressing surface, a defined positioning of the adhesive film on the book cover is possible, ensuring high repeatability.
[0007] The book cover can be placed onto the pressing surface of the pressing device either manually or automatically.
[0008] Preferably, the pressure stamp is guided with its pressing surface onto the pressing surface, which is fixedly mounted on the base frame of the device and is particularly heatable, and controlled with a contact pressure and a contact duration. Since only one of the two surfaces is moved, positioning accuracy can be increased. Furthermore, a simple design of such a pressing device is possible.
[0009] Furthermore, the gripping device preferably has at least one suction cup, and a vacuum is applied to grip the adhesive film section. This enables easy handling of an adhesive film. Preferably, an array of several suction cups or at least one large-area suction cup is provided, which are controlled jointly, so that the entire adhesive film section can be gripped and transferred to the pressing device without distortion.
[0010] Furthermore, it is preferably provided that the pressure stamp of the pressing device has at least one suction cup, and a vacuum is applied to grip the adhesive film section. The pressure stamp thus has a dual function. On the one hand, it enables the adhesive film section to be gripped until the pressure stamp is transferred to the pressing surface. After that, the vacuum is released, and the pressure stamp exerts a pressing force with its pressing surface on the pressing surface or the book cover.
[0011] Preferably, when transferring the adhesive film section from the gripper device to the pressure pad, the vacuum of the gripper device is released after the vacuum has been applied to the pressure pad. This enables a secure transfer and a precise positioning.
[0012] Advantageously, a cutting device is provided between the gripping station and the pressing device, by which the adhesive film section gripped in the pressing device is separated from the adhesive film section positioned in the gripping station. Preferably, a cutting element of the cutting device and a counter-blade or further cutting element on a cutting drive on a base frame of the device are provided on the gripping device. This arrangement enables a free end of the strip-shaped adhesive film section to always be transferred from the gripping device to the pressing die in a defined position. This also enables precise positioning of the adhesive film section for transfer to the pressing die.The adhesive film section gripped by the pressure stamp is only separated from the strip-shaped adhesive film when the gripping device in the gripping station has firmly gripped the subsequent further adhesive film section.
[0013] Furthermore, a pressure flap with a pressure bar is preferably provided on the pressure stamp. This pressure bar is activated after the adhesive film section has been cut and before the pressure stamp is pressed against the pressure surface, so that the pressure bar is transferred into a plane of the pressure surface of the pressure stamp. This allows the pressure surface to be enlarged and the space required for the cutting device between the pressure device and the gripping station to be bridged.
[0014] A further advantageous embodiment of the method provides that the pressing surface of the die is heated to a temperature within a temperature range of 20 to 150 °C. Depending on the adhesive film used, a working temperature is set, which the book cover absorbs after being placed on the pressing surface in order to ensure secure adhesion of the adhesive film to the book cover.
[0015] Furthermore, the adhesive film is preferably provided on one side with a release layer, in particular a silicone paper, on a roll or reel. On the one hand, providing it on a roll enables continuous processing. On the other hand, the release layer, in particular the silicone paper, allows for easy separation of the adhesive film from the contact surface. Furthermore, the pre-laminated book covers are stackable and can be easily stored or stored for further processing.
[0016] Furthermore, film tension and / or removal of the at least one adhesive film section is preferably controlled by a belt braking device. This allows the belt tension to be maintained to create defined working conditions.
[0017] Furthermore, a hot-melt adhesive film or a heat-reactive adhesive film is preferably applied. This allows an adhesive effect to be achieved by heating the book cover, whereas after cooling and, if necessary, peeling off a release liner or silicone paper, the exposed surface of the adhesive film becomes non-adhesive. This simplifies further processing.
[0018] The object underlying the invention is further achieved by a device for applying an adhesive film section separated from a strip-shaped adhesive film to a book cover, for which a base frame and a housing at least partially surrounding the base frame are provided, as well as a winding holder for the adhesive film and a gripping station to which an adhesive film section of the adhesive film is fed from the winding holder and with a pressing device in which a gripping device of the gripping station is movable for transferring the adhesive film section and which has a pressing stamp for taking over the adhesive film section from the gripping device and with a cutting device by means of which the adhesive film section transferred in the pressing device can be separated from the adjacent adhesive film section in the gripping station and with a pressing surface of the pressing device for positioning a book cover,The pressure stamp and the pressure surface can be positioned relative to each other under pressure, so that the adhesive film section is adhered to the book cover. Such a device has a simple design for producing a pre-laminated book cover. The sequential arrangement of the winding holder, the gripping station, and the pressure device also enables a high degree of repeatability when applying the adhesive film section to the book cover.
[0019] Preferably, the gripping station comprises a pressure plate fixedly mounted on the base frame, having a pressure surface, and the gripping device with at least one suction cup associated with the pressure plate. This allows the gripping device to be moved against the pressure plate to enable a defined pick-up of the adhesive film section in the gripping station.
[0020] The gripping device is preferably movable by a linear axis drive. In particular, at least one linear axis movable in the X and Z directions is provided. This allows for a simple transfer of the adhesive film section from the gripping station to the pressing device. Such linear axis systems can be controlled pneumatically, hydraulically, electrically, electromagnetically, or similarly.
[0021] Furthermore, at least one guide device for lateral alignment of the adhesive film section in the gripping station is preferably provided in and / or in front of the gripping station. This lateral alignment is preferably related to the Y-direction. The Y-direction is transverse to the feed direction of the adhesive film. This allows a direction in the feed plane of the adhesive film into the gripping device to be set.
[0022] The guide device can be formed by at least one guide plate, which is provided on the inlet side of the pressure plate. Alternatively, the guide device can be formed by guide discs, which are provided on a deflection roller located directly upstream of the gripping station. Aligning the deflection roller with respect to the Y-axis can, in turn, enable the adhesive film section to be aligned.
[0023] A cutting device is provided between the pressing device and the gripping station. In particular, a cutting element of the cutting device can be provided on a front side of the gripping device facing the pressing device. This arrangement of the cutting device enables precise alignment of the adhesive film section in the X-direction, since the cut edge forms the leading edge of the adhesive film section that is transferred to the pressing device.
[0024] A further advantageous embodiment of the pressing device provides that it has a linear axis drive which moves the pressing surface of the pressing stamp onto the pressing surface.
[0025] The pressure stamp of the pressing device has at least one suction cup in order to fulfil the gripping function in addition to the pressing function.
[0026] Advantageously, a pressure flap is provided on the pressure die, which can be activated upon a movement of the pressure die toward the pressure surface, so that it enlarges the pressure surface of the pressure die with a pressure bar. This allows the cutting device to be positioned between the gripping device and the pressure device.
[0027] The device can be controlled in semi-automatic mode. For this purpose, the housing preferably has an access area for manually placing and positioning the book cover on the contact surface of the pressing device. In fully automatic mode, a conveyor belt or handling device can lead into the feed area to feed the book cover to the contact surface. Removal can also be performed automatically by a conveyor belt or handling device.
[0028] The contact surface of the die of the pressing device is preferably heatable. This can be done by heating cartridges, which are powered, for example. A heating medium can also be flowed through this contact surface or heated by radiation.
[0029] Furthermore, the pressing surface of the die preferably has an alignment device. This facilitates a defined alignment when the book cover is placed manually or mechanically on the pressing surface, so that the adhesive film section can then be positioned on the book cover with a high degree of repeatability.
[0030] Furthermore, the pressing surface of the die preferably has an ejector device. This is activated after the pressing die has been returned to its starting position. This facilitates the removal of the pre-laminated book cover.
[0031] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features shown in the description and the drawings can be used individually or in any combination according to the invention. They show: Fig. 1 a perspective view of a book-like document, Fig. 2 a schematic view of a pre-laminated book cover, Fig. 3 a schematic side view of a device for applying a strip-shaped adhesive film to a book cover, Fig. 4 a schematic side view of the device according to Fig. 3 in a further step, and Fig. 5 a further schematic side view of the device according to Fig. 3 in a further step.
[0032] In Fig. 1 shows a perspective view of a book-like document 11, in particular a security document. This book-like document 11 is, for example, an identification document such as a passport. The document 11 comprises, for example, a book cover 12. On an inner side of the book cover 12, an endpaper may be provided, which is attached to the book cover 12. A data page 17 and one or more inner pages 18 can be connected to one another via a seam 16 to form a book block 15. Alternatively, only inner pages 18 may be provided. If a book cover 12 and, in particular, the endpaper 14 are provided, at least this endpaper 14 is also connected to the book block 15 via the seam 16. The inner pages 18 of the book-like document 11 serve to accommodate visas, stamps, or other entries. The data page 17 consists, for example, of a data carrier 20 and a flap 23 attached thereto.The data page 17, in particular the data carrier 20, can be designed, for example, according to the ICAO standard and include an image 19 of the document holder, a machine-readable area 21 (MRZ), and further personalization data 22. The personalization data 22 are provided within the data carrier 20. The flap 23 of the data carrier 20 extends beyond the seam 16. This flap 23 also includes a seam area in which the seam 16 is formed. In addition or alternatively, an adhesive and / or welded connection can be provided for the seam 16 in order to bind the flap 23 into the book-like document 11, in particular the book block 15.
[0033] In Fig. 2 shows a book cover 28 for the book binding 12 with an adhesive film 29 applied thereto. This pre-laminated book cover 28 serves as a semi-finished product for producing the book cover 12 with the endpaper 14 applied thereto. For example, a cover can be applied to an outer side of the book cover 28 and folded over toward one adhesive film section 45 of an adhesive film 29. The endpaper 14 of the book block 15 can then be applied to the adhesive film and glued thereto.
[0034] The adhesive film 29 is preferably designed as a hot-melt adhesive. A heat-reactive adhesive or heat-reactive hot-melt adhesive can also be used, which is designed as a continuous layer in the form of a film or adhesive strip in a temperature range at ambient temperature. This adhesive film 29 can advantageously be provided on a roll or a reel. The adhesive film 29 is preferably provided on one side with a release layer, in particular a silicone paper.
[0035] The book cover 28 can be made of paper, cardboard, a fabric, plastic or a combination of the individual layers.
[0036] The book cover 28 can also be used for a book-like document with or without the application of an additional decorative layer or an additional wrapping on its outer side.
[0037] In Fig. Figure 3 shows a schematic side view of a device 31 for applying the strip-shaped adhesive film 29 to the book cover 28. The device 31 comprises a base frame 32 with a housing 33, which surrounds individual components that are connected to or with the base frame 32. A roll of the adhesive film 29 is provided on a winding holder 34. Downstream of this winding holder 34 are deflection rollers 35, which guide the adhesive film 29 to the gripping station 36. To maintain tape tension, the winding holder 34 can comprise a tape brake. Alternatively, the deflection rollers 35 can be designed to adjust tape tension.
[0038] The gripping station 36 comprises a pressure plate 37 fixedly mounted on the base frame 32, as well as a gripping device 38. This gripping device 38 is provided on a linear axis drive 39, which comprises at least one linear axis 41 in the X direction and at least one further linear axis 42 in the Z direction. This allows the gripping device 38 to be moved.
[0039] The gripping device 38 has a gripping surface with at least one suction cup 44 on an end face facing the pressure plate 37. The suction cup(s) 44 allow an adhesive film section 45 of the adhesive film 29 arranged in the gripping station 36 to be grasped by the gripping device 38 by lifting it via the linear axis 42 and to be brought into contact with the gripping surface.
[0040] The adhesive film 29 is fed to the gripping device 38 via a deflection roller 35 that precedes the gripping station 36 and is positioned relative to the gripping station 36 in such a way that feeding is possible almost parallel or parallel to the pressure plate 37. This deflection roller 35 has a deflection surface 48 to adjust a lateral alignment of the adhesive film 29 in the Y direction relative to the gripping station 36. These deflection surfaces 48 can also be provided as so-called flanged discs, in particular as clamping rings, on the deflection roller 35.
[0041] A pressing device 50 is provided on the output side of the gripping station 36. This pressing device 50 comprises a pressing ram 51, which can be controlled by a linear axis drive 52 for vertical movement in the Z direction. Furthermore, the pressing device 50 comprises a pressing surface 53 on a die 54, which is preferably fixedly provided in the base frame 32. The pressing ram 51 has at least one suction cup 55 on a ram surface. This at least one suction cup 55 is integrated into the ram surface of the pressing ram 51, so that the adhesive film section 45 of the adhesive film 29 can rest against it.
[0042] A cutting device 60 is provided between the pressing device 50 and the gripping station 36. This cutting device 60 comprises a first and second cutting element 61, 62, which cuts the adhesive film 29.
[0043] In the exemplary embodiment, a first cutting element 61 is fixedly provided on an end face of the gripping device 38, which faces the pressing device 50. The second cutting element 62 is arranged fixedly in the X direction and pivotable relative to the gripping device 38, which is controlled by a drive 63 to perform a separating cut. This forms a defined stop or a defined front end of the adhesive film section 45 of the adhesive film 29, at which the transfer to the pressing stamp 51 is aligned.
[0044] Above the pressure stamp 51, a pressure flap 65 is provided, which in Fig. 3 is shown in a partially pivoted and inactive position. This pressure flap 65 can be pivoted clockwise by a drive 66, so that a pressure web 67 is positioned in the plane of the stamping surface of the pressure stamp 51 and acts simultaneously with the pressure stamp 51 on the pressure surface 53.
[0045] The pressing surface 53 of the die 54 has an alignment device 71. This can be formed, for example, by three pins or studs arranged offset from one another. This allows the book cover 28 to be aligned when placed on the pressing surface 53.
[0046] Furthermore, the pressing surface 53 can have an ejector device 72. This allows the pre-laminated book cover 28 to be slightly lifted from the pressing surface 53 for easy removal during manual removal.
[0047] A drawing-in operation, which is carried out in preparation for the subsequent application of the adhesive film to a book cover, comprises the following steps: A roll of adhesive film 29 is placed on the winding holder 34. A first end of the adhesive film 29 is placed around the deflection rollers 35. The free film end is then guided through the gripping station 36 so that it is positioned in a feed area 75 and held by the operator. Subsequently, a movement of the linear axis 42 of the gripping device 38 in the gripping station 36 is controlled in order to clamp the adhesive film 29 against the pressure plate 37. At least one suction cup 44 of the gripping device 38 is switched on. A vacuum is thus applied. Subsequently, the cutting device 60 is controlled in order to perform a first separating cut. The cutting device 60 is then opened again. The operator can remove the cut-off film end from the housing 33.
[0048] In the device 31 according to the illustrated embodiment, in which the insertion of the book cover 28 for applying the adhesive film 29 is carried out manually, the above-described steps for the insertion operation can be carried out by actuating a button from a two-hand operation with appropriate safety measures from an operating terminal of a machine control 79 on an outer side of the housing 33.
[0049] A process cycle for applying the strip-shaped adhesive film 29 to the book cover 28 can proceed as follows, preferably starting from the previously described drawing-in operation. The book cover 28 is placed and aligned on the pressing surface 53 on the die 54 via the feed area 75. The gripping device 38 with the adhesive film section 45 of the adhesive film 29 held by suction or under vacuum is lowered slightly by the linear axis 42. The linear axis 41 is then controlled so that the gripping device 38 is moved into the pressing device 50. The adhesive film 28 is thereby pulled off the roll. As a result, another adhesive film section 47 of the adhesive film 29 is positioned in the gripping station 36. The gripping device 38 is positioned between the pressing stamp 51 and the pressing surface 53.A travel movement is then initiated in the direction of the pressure stamp 51 until the adhesive film section 45 of the adhesive film 29 rests against the pressure stamp 51. If necessary, the pressure stamp 51 can also be moved towards the gripping device 38. The adhesive film section 45 of the adhesive film 29 is then transferred. The at least one suction cup 55 in the pressure stamp 51 is subjected to a vacuum. The vacuum from the suction cup 44 on the gripping device 38 is then switched off. The gripping device 38 is moved downwards along the Z-axis, then retracted along the X-axis into the gripping station 36 and then moved upwards again in the Z-direction in order to clamp and grip the additional adhesive film 29 or the adhesive film section 45 / 47 now located in the gripping station 36. The cutting device 60 is then activated and a separating cut is made.
[0050] Subsequently, the pressure stamp 51 is moved towards the contact surface 53 and the pressure flap 65 is closed. The adhesive film section 45 on the pressure stamp 41 is positioned on the book cover 28. By heating the contact surface 53, the book cover 28 is heated, so that the adhesive film section 45 adheres to the book cover 28. This working position of the pressure stamp 51 relative to the contact surface 53 is shown in a further side view of the device 31 in Fig. 5 shown.
[0051] After a predetermined pressing time, the pressure stamp 51 is moved back to its starting position by the linear drive 52. The pressure flap 65 is pivoted back to its starting position counterclockwise so that no collision occurs with the cutting device 60. If an ejector device 72 is assigned to the pressing surface 53, this is actuated, allowing easy removal of the pre-laminated book cover 28.
[0052] Subsequently, a new book cover 28 is placed on the pressing surface 53 and another process cycle begins.
[0053] From the Fig. For example, Figure 5 shows the positioning of a machine control 79. This machine control 79 controls and monitors the individual components for applying the adhesive film section 45 of the adhesive film 29 to the book cover 28.
