Description

Technical Field

[0001] The present invention relates to a method for imparting manufacturing information to a pasting medium by a pasting device that thermocompression-bonds a foil material to a base material.

Background Art

[0002] In recent years, foils (metallic foils, holograms, and foils with a display technique "OVD (Optical Variable Device)" that utilizes light interference such as diffraction gratings) have been pasted on valuable printed matter such as banknotes, securities, and passports that require security. In addition, these foils have also come to be pasted on various credit cards, IC cards, gift certificates, etc., and these valuable printed matters cover a wide range. The reason why foils are used for many valuable printed matters is that foils have the property that the color and image change when the viewing angle is changed, so anyone can easily distinguish between genuine and fake, and it is difficult to counterfeit.

[0003] As an example of such valuable printed matter, in the manufacturing process of securities, there are a process of pasting a foil, a process of manufacturing a paper that has been subjected to embossing, etc., a process of cutting into single sheets, a process of inspecting single sheets, and a process of printing on single sheets. Also, since there are multiple manufacturing devices even in the same process, in order to perform quality control and quantity control, information such as numbers, barcodes, and two-dimensional codes is imparted to and managed on single sheets as manufacturing information in each process.

[0004] For example, in the printing process, manufacturing information such as the printing date and the device number of the printer provided in the printing machine is imparted to the margin of the single sheet. Also, a certain quantity of single sheets stacked together is regarded as one lot, and manufacturing information is described on a record sheet attached to each lot. On the other hand, in the case of a pasting device, since a device for imparting manufacturing information such as an inkjet printer is often not mounted due to the mechanical structure, manufacturing information is not imparted to each single sheet in the pasting process, and manufacturing information such as the pasting date and the device number of the pasting device is only described on a record sheet attached to each lot.

[0005] As a prior art, as a printing machine for imparting code information to a printed matter, a sheet-fed printing machine is disclosed in which an inkjet printer for printing print information such as numbers, barcodes, two-dimensional codes, etc. on a printing target is detachably provided (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0007] The sheet-fed paper that has become waste paper in an inspection process or the like, which is a subsequent process to the pasting process, is managed in units of sheet-fed paper rather than in units of lots, so it is difficult to compare it with a record sheet on which manufacturing information is described. Therefore, even if information on defective products is obtained from the subsequent process, it has been difficult to identify the pasting device in which the defective products occurred. For this reason, it has taken time to identify the manufacturing device and the cause of the defective products.

[0008] Also, generally in a series of manufacturing processes for valuable printed matter, the quantity is managed in units of lots in which a certain quantity is stacked, and is transported between processes as a printed matter laminate in which several lots to several tens of lots are stacked, and is stored in a product warehouse.

[0009] However, since the technology of Patent Document 1 imparts manufacturing information to either the front or back of the printed matter, in order to confirm the manufacturing information in the state of the printed matter laminate, it is necessary to take out and check each lot, and the working efficiency was poor.

[0010] Also, Patent Document 1 has a problem that it is necessary to newly provide a device for imparting manufacturing information such as an inkjet device, which leads to an increase in the size of the machine and manufacturing costs.

[0011] The present invention aims to solve the above problems, and in a pasting device, by processing an engraving plate pre-provided in the device, a method for imparting manufacturing information to a pasting medium capable of easily imparting manufacturing information to a single sheet of paper without providing a new device is provided.

Means for Solving the Problems

[0012] The present invention is a method for imparting manufacturing information to a pasting medium in which a foil material is pasted on a base material by thermocompression bonding, and at the same time as the thermocompression bonding of the foil material, at least one information pattern corresponding to the manufacturing information is imparted to the base material as an indentation.

[0013] Further, the present invention is a method for imparting manufacturing information to a pasting medium, characterized in that the information pattern is imparted to a position covering an end portion of the base material.

Effects of the Invention

[0014] According to the pasting device of the present invention, it is possible to easily impart manufacturing information to a single sheet of paper without providing a new device, and by confirming the manufacturing information imparted as an indentation, it becomes easy to identify the pasting device that manufactured defective products, and the cause of the defective products can be quickly identified. In addition, since the manufacturing information can be easily observed even when observing the printed matter laminate from the side, the work efficiency can be improved.

Embodiments for Carrying Out the Invention

[0016] Embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below, and includes various other embodiments within the scope of the technical idea described in the claims.

[0017] First, with reference to FIG. 1, the base material (S), the foil material (H), and the foil carrier tape (10) used in the present invention will be described.

[0018] (Base material) In the embodiments of the present invention, the base material (S) may be a paper or a plastic sheet used alone, or a laminate of a paper and a plastic sheet, as long as it is a material to which the foil material (H) can be attached. Further, it may be a material in which at least one surface of the paper is coated. Note that the base material (S) to which the foil material (H) is thermocompression-bonded may be used in its original form, or may be divided into a predetermined size and used for banknotes, travel documents, securities, tickets, certificates, and the like. Further, the base material (S) may be unprocessed, or may be one that has been previously printed or otherwise processed. In this specification, the base material (S) to which the foil material (H) is thermocompression-bonded is referred to as an attachment medium.

[0019] (Foil material) The foil material (H) is a display technique “OVD (Optical Variable Device)” that utilizes light interference such as a metal foil, a hologram, or a diffraction grating, and is provided to the base material (S) for the purpose of preventing forgery. The foil material (H) may be provided as one or a plurality of patterns (patch type) or as a strip-shaped pattern (stripe type) with respect to the base material (S) depending on the purpose of use and design. Further, the foil material (H) may be provided to an unprocessed base material (S), or may be provided to a base material (S) that has been previously processed such as printing or die-cutting.

[0020] (Foil carrier tape) FIG. 1(a) is a cross-sectional explanatory view schematically showing the foil carrier tape (10) used in the present invention. The foil carrier tape (10) in the embodiments of the present invention includes a base film (10a), a transparent protective layer (10b) laminated on the surface of the base film (10a) so as to be peelable, a light-reflective metal layer (10c) formed on the surface of the protective layer (10b), and an adhesive layer (10e) laminated on the surface of the metal layer (10c), and includes an uneven structure (10d) of a diffraction grating as needed.

[0021] Also, as shown in Fig. 1(a), with the foil carrier tape (10) and the base material (S) arranged, due to the shape of the foil - attaching engraving (4a’) provided on the engraving plate (4a), from above the base film (10a), by being heated and pressurized, the foil material (H) (the part shown by the dashed line in Fig. 1(a)) is thermocompression - bonded from the foil carrier tape (10) to the base material (S). Specifically, the adhesive layer (10e) of the foil carrier tape (10) melts and is thermocompression - bonded to the base material (S), and at the same time, the part between the base film (10a) and the protective layer (10b) in the foil carrier tape (10) peels off, and the foil material (H) is thermocompression - bonded to the base material (S).

[0022] Fig. 1(b) is a diagram showing the state of the foil material (H) thermocompression - bonded to the base material (S) and the foil carrier tape (10) from which the foil material (H) has been peeled off by heating and pressurization by the foil - attaching engraving (4a’). Regarding the foil carrier tape (10) from which the foil material (H) has been peeled off by thermocompression - bonding, it is conveyed and recovered, and a new foil carrier tape (10) is introduced.

[0023] (Arrangement of the foil) Fig. 2 is a diagram for explaining the arrangement of the foil carrier tape (10) used in the pasting device (1) of the present invention, and shows only the configuration of the pasting device (1) necessary for the explanation. As shown in Fig. 2, the foil carrier tape (10) is installed in a wound state on the foil supply means (7a) and is paid out. Also, the pasting device (1) is provided with a plurality of rollers (7c) for maintaining tension and performing direction adjustment.

[0024] Next, the foil carrier tape (10) goes around the paper - feeding part (2) side and is arranged between the engraving plate (4a) and the pressure plate (4b) of the pasting part (4). Also, after thermocompression - bonding in the pasting part (4), the foil carrier tape (10) is moved in the conveying direction (V1) of the base material (S) and sent to the foil recovery means (7b).

[0025] Note that the foil supply means (7a), the foil recovery means (7b), and the plurality of rollers (7c) are not limited to the above-described configuration. In the sticking portion (4), as long as the foil carrier tape (10) is conveyed from the paper feeding portion (2) side to the discharging portion (6) side, and after the foil material (H) is thermocompression-bonded to the base material (S), the foil carrier tape (10) moves in the conveying direction (V1) of the base material (S), any mechanism may be used. The above is the description of the base material (S), the foil material (H), and the foil carrier tape (10) used in the present invention.

[0026] (Sticking device) Next, an example of the sticking device (1) for imparting an information pattern corresponding to production information in the present invention will be described. FIG. 3 is a schematic view showing the entirety of the sticking device (1) of the present invention. The sticking device (1) includes at least a paper feeding portion (2), a conveying portion (3), a sticking portion (4), a separating portion (5), and a discharging portion (6). Each will be described below.

[0027] (Paper feeding portion) The paper feeding portion (2) shown in FIG. 3 is a mechanism for feeding the stacked base materials (S) one by one to the conveying portion (3). The mechanism of the paper feeding portion (2) is not limited as long as it can feed the base materials (S) one by one to the conveying portion (3). For example, it may be provided with a mechanism for sucking the stacked base materials (S) with air and conveying them to the feeder table by a roller or a belt.

[0028] (Conveying portion) The conveying portion (3) shown in FIG. 3 is a mechanism for holding the base materials (S) fed from the paper feeding portion (2) one by one and conveying the base materials (S) to the sticking portion (4), and includes at least a gripper (3a) for gripping the base material (S), a gripper bar (not shown) made of a plate-like member, and a chain (3c).

[0029] FIG. 4 is a diagram schematically showing the conveying portion (3) in the sticking device (1), and will be further described based on this. As shown in FIG. 4, the conveying portion (3) is provided with a plurality of grippers (3a) for gripping the leading end (S’) of the base material conveyed from the paper feeding portion (2) on the gripper bar (3b).

[0030] The gripper (3a) is a member that holds the tip (S’) of the base material, and holds the base material (S) by opening and closing the claws of the gripper (3a). The number of grippers (3a) provided on the gripper bar (3b) can be appropriately selected according to the size of the base material (S) to be conveyed. Also, the position of the gripper (3a) is not particularly limited as long as it can stably hold and convey the base material (S).

[0031] The gripper bar (3b) is a plate-shaped member, and the ends of the plate-shaped member are respectively fixed to a chain (3c) each provided on a side surface along the conveyance direction of the pasting device (1). Thereby, the gripper (3a) and the gripper bar (3b) circulate inside the pasting device (1) along the orbit of the chain (3c).

[0032] As shown in FIG. 4, the chain (3c) has sprockets (3d) to which power is transmitted from a main motor (not shown) respectively arranged on both sides of the paper feeding section (2) side and the discharging section (6). When the sprockets (3d) rotate from the paper feeding section (2) toward the discharging section (6), the chain (3c) connected to the sprockets (3d) rotates. Also, the conveying section (3) circulates from the paper feeding section (2) to the discharging section (6) so as not to interfere with the above-described foil supply means (7a) and foil recovery means (7b). Also, as shown in FIG. 5, a plurality of gripper bars (3b) are fixed to the chain (3c). In the present invention, a belt may be used instead of the chain (3c).

[0033] (Pasting section) The pasting section (4) shown in FIG. 3 is a mechanism for thermocompression bonding the foil material (H) from the foil carrier tape (10) to the base material (S), and has at least an upper fixed printing plate (4a) and a pressure plate (4b) provided below the printing plate (4a) so as to move in a reciprocating vertical motion toward the printing plate (4a).

[0034] FIG. 6 shows an operation explanatory diagram of the sticking portion (4). FIG. 6(a) is a view showing a state in which the tip (S’) of the base material is held by the gripper (3a) and the base material (S) is guided between the foil carrier tape (10) and the pressure plate (4b). At this time, the printing plate (4a) and the pressure plate (4b) are stopped in a separated state.

[0035] FIG. 6(b) is a view showing a state in which the gripper (3a) holds the tip (S’) of the base material and has completed the drawing-in between the foil carrier tape (10) and the pressure plate (4b). The gripper (3a) once stops moving in that state. Also, with the gripper (3a) stopped, the pressure plate (4b) rises while pushing up the base material (S).

[0036] FIG. 6(c) is a view showing a state in which, with the gripper (3a) stopped, the pressure plate (4b) further rises, and the foil material (H) is thermocompression bonded from the foil carrier tape (10) to the base material (S) in the shape of the foil sticking print (4a’) on the base material (S). In the present invention, among the printing plates (4a), a manufacturing information imparting print (4a’’) is provided at a position corresponding to the rear end of the base material (S), and an information pattern (4d) corresponding to the manufacturing information is imparted to the base material (S) simultaneously with the thermocompression bonding of the foil material (H). Details will be described later.

[0037] FIG. 6(d) is a view showing a state in which the thermocompression bonding has ended. At this time, the pressure plate (4b) descends while supporting the base material (S).

[0038] FIG. 6(e) is a view showing a state in which, as the pressure plate (4b) further descends, the gripper (3a) resumes movement in the conveying direction (V1) and moves to the discharge portion (6) while holding the tip (S’) of the base material. In this way, the gripper (3a) holding the tip (S’) of the base material intermittently conveys the base material (S) by stopping once when passing through the sticking portion (4) and resuming operation after the foil material (H) is thermocompression bonded. Also, it returns to the state shown in FIG. 6(a), and the introduction of the subsequent base material (S) starts between the foil carrier tape (10) and the pressure plate (4b).

[0039] In the sticking part (4), since the pressure, temperature, and thermocompression time applied during thermocompression may be appropriately adjusted according to the type and characteristics of the base material (S) and the foil (H), etc., they are not particularly limited. However, in the present invention, since manufacturing information is imparted to the base material (S) as indentations (embossing by sticking pressure), it is desirable that the pressure be 40 tons or more.

[0040] FIG. 7(a) shows a side configuration diagram of the sticking part (4) in the sticking device (1) for sticking the stripe-shaped foil material (H). As shown in FIG. 7(a), the engraving plate (4a) includes a foil sticking engraving (4a') formed in a convex shape on its lower side and an engraving (4a'') for imparting manufacturing information. Further, between the engraving plate (4a) and the pressure plate (4b), a foil carrier tape (10) is arranged in the direction from the paper feeding part (2) side to the discharging part (6) side (conveying direction (V1)). Further, a gripper (3a) holding the tip (S') of the base material introduces the base material (S) between the foil carrier tape (10) and the pressure plate (4b).

[0041] FIG. 7(b) shows a plan configuration diagram of the sticking part (4). In FIG. 7(b), only the foil sticking engraving (4a') and the engraving (4a'') for imparting manufacturing information formed in a convex shape are shown, and the engraving plate (4a) is omitted from the illustration.

[0042] [[ID=]12]As shown in FIG. 7(b), in the present embodiment, a strip-shaped foil sticking engraving (4a') is arranged at a position corresponding one-to-one to the position of the foil carrier tape (10). In the present embodiment, the foil sticking engraving (4a') can use any shape. Further, in FIG. 7(b), the foil carrier tape (10) and the foil sticking engraving (4a') are arranged in four rows each, but they can be appropriately arranged according to the required product specifications, the design of the foil to be stuck, etc.

[0043] FIG. 8 is a side view and a plan view of an attaching portion (4) in an attaching device (1) for attaching a patch-type foil material (H). Since the basic configuration is the same as that in FIG. 7, detailed description thereof is omitted. As shown in FIGS. 8(a) and 8(b), in order to attach the patch-type foil material (H), the foil attaching print (4a') has a shape provided with convex portions pointwise.

[0044] (Print for imparting manufacturing information) Here, the print (4a'') for imparting manufacturing information, which is a feature point of the present invention, will be described. The print (4a'') for imparting manufacturing information is for imparting manufacturing information to the base material (S). As shown in FIG. 7, it is preferably arranged at a position applied to the end portion of the base material (S) during thermocompression bonding and at a position not interfering with the foil carrier tape (10). The end portion here refers to two sides (side AB or side CD shown in FIG. 7) corresponding to the width direction of the base material (S) (the direction along the conveyance direction (V1)) or a side (side BC shown in FIG. 7) where the base material (S) is not supported by the gripper (3a). By forming an indentation when the print (4a'') for imparting manufacturing information is applied to the end portion of the base material (S) during thermocompression bonding, it becomes possible to confirm the manufacturing information even when observed from the side of the lot. Note that, as shown in FIG. 8, the print (4a'') for imparting manufacturing information may not be applied to the end portion of the base material (S) and may all be located on the base material (S). In that case, the manufacturing information cannot be confirmed from the side of the lot, but the manufacturing information can be confirmed when checking a single sheet of paper.

[0045] Using FIG. 9, the relationship between the height of the imprint for foil attachment (4a') and the imprint for providing manufacturing information (4a'') will be described in detail. The height referred to here is the length protruding from the imprint plate (4a). The imprint for foil attachment (4a') is described as having a height T, and the imprint for providing manufacturing information (4a'') is described as having a height t. The height T of the imprint for foil attachment (4a') is not particularly limited. As an example, it has a height of about 10 mm. The imprint for providing manufacturing information (4a'') needs to have a lower height than the imprint for foil attachment (4a'). Although it depends on the pasting conditions, it is desirable that T - t is 0.07 to 0.1 mm. The reason is that if T - t is less than 7 mm, the pressure applied during thermocompression bonding becomes too strong and there is a risk of damaging the base material (S). If T - t is greater than 0.1 mm, the pressure applied during thermocompression bonding becomes too weak and the indentation becomes too thin to confirm the manufacturing information.

[0046] The manufacturing information in the present invention refers to the equipment number of the manufacturing equipment, the manufacturing factory, the manufacturing date, etc. The imprint for providing manufacturing information (4a'') has an imprint pattern (4c) in a shape corresponding to the manufacturing information.

[0047] An example of the shape of the imprint for providing manufacturing information (4a'') and the imprint pattern (4c) is shown in FIG. 10. The imprints for providing manufacturing information (4a'') shown in FIGS. 10(a) to 10(c) have a convex imprint pattern (4c) of one line, two lines, and three lines as a shape corresponding to the manufacturing information. For example, when the equipment number is associated with the imprint pattern (4c) as manufacturing information, the one line in FIG. 10(a) represents Machine No. 1 of the pasting device (1), the two lines in FIG. 10(b) represent Machine No. 2 of the pasting device (1), and the three lines in FIG. 10(c) represent Machine No. 3 of the pasting device (1). In this way, it becomes possible to provide manufacturing information.

[0048] The manufacturing information - attaching engraving (4a'') shown in FIGS. 10(d) to (f) has an engraving pattern (4c) consisting of a circle as a shape corresponding to the manufacturing information, and the number of circles is different corresponding to the manufacturing information. Note that FIGS. 10(a) to (c) show a convex engraving pattern (4c), while FIGS. 10(d) to (f) show a concave engraving pattern (4c). For example, when the manufacturing factory is associated with the engraving pattern (4c) as the manufacturing information, the product with one circle in FIG. 10(d) is a product manufactured by the pasting device (1) of Factory A, the product with two circles in FIG. 10(e) is a product manufactured by the pasting device (1) of Factory B, and the product with three circles in FIG. 10(f) is a product manufactured by the pasting device (1) of Factory C. Thus, it becomes possible to attach the manufacturing information.

[0049] Here, with reference to FIG. 10, the detailed positional relationship when the manufacturing information - attaching engraving (4a'') is applied to the end of the base material (S) during thermocompression bonding will be described. When the manufacturing information - attaching engraving (4a'') is applied to the end of the base material (S), the engraving pattern (4c) included in the manufacturing information - attaching engraving (4a'') needs to be applied to the end of the base material (S). As an example, in FIG. 10(d), when the position of line A - A' is applied to the end of the base material (S), since the manufacturing information is applied to the end of the base material (S), the manufacturing information can be confirmed even when observed from the side of the lot. However, when the position of line B - B' is applied to the end of the base material (S), since the manufacturing information is not applied to the end of the base material (S), the manufacturing information cannot be confirmed even when observed from the side of the lot.

[0050] FIG. 11 is a cross - sectional view taken along line A - A' of the manufacturing information - attaching engraving (4a'') shown in FIG. 10. For example, the cross - sectional view taken along line A - A' of the manufacturing information - attaching engraving (4a'') in FIG. 10(a) is as shown in FIG. 11(a), and it has one convex engraving pattern (4c) on the upper part of the manufacturing information - attaching engraving (4a''). Similarly, the manufacturing information - attaching engraving (4a'') shown in FIG. 11(b) has two convex engraving patterns (4c), and the manufacturing information - attaching engraving (4a'') shown in FIG. 11(c) has three convex engraving patterns (4c).

[0051] Next, in FIGS. 10(d) to (f), since the engraved pattern (4c) is formed in a concave shape, in FIG. 11(d), the portion indicated by the broken line has one concave engraved pattern (4c). Similarly, in FIG. 11(e), the portion indicated by the broken line has two concave engraved patterns (4c), and in FIG. 11(f), the portion indicated by the broken line has three concave engraved patterns (4c).

[0052] FIG. 12 is an example of a precious printed matter in which an information pattern (4d) corresponding to manufacturing information is imparted to a base material (S) using the manufacturing information imparting engraving (4a'') of FIGS. 10(a) to (c). Note that FIG. 12 has a stripe-shaped foil material (H) attached thereto. Since the pressure by the manufacturing information imparting engraving (4a'') is applied to the information pattern (4d) of FIG. 12 simultaneously with the thermocompression bonding of the foil material (H) at a position covering the end portion of the base material (S) as described above, the shape of the engraved pattern (4c) is imparted to the base material (S) as an indentation and can be observed as the information pattern (4d). Therefore, the precious printed matter shown in FIG. 12(a) has a single-line information pattern (4d) imparted by the engraved pattern (4c) of FIG. 10(a), and since the apparatus number is associated as manufacturing information, it can be specified that it is a product manufactured by the No. 1 machine of the pasting apparatus (1). Similarly, the precious printed matter shown in FIG. 12(b) can be specified as a product manufactured by the No. 2 machine of the pasting apparatus (1), and the precious printed matter shown in FIG. 12(c) can be specified as a product manufactured by the No. 3 machine of the pasting apparatus (1).

[0053] FIG. 13 shows an example of a precious printed matter in which an information pattern (4d) corresponding to manufacturing information is imparted to a base material (S) using the imprint (4a'') for imparting manufacturing information shown in FIGS. 10(d) to (f). Note that a patch-type foil material (H) is attached to FIG. 13. Similar to FIG. 12, since the pressure by the imprint (4a'') for imparting manufacturing information is applied to the position of the information pattern (4d) in FIG. 13 on the end portion of the base material (S) simultaneously with the thermocompression bonding of the foil material (H), the shape of the imprint pattern (4c) is imparted to the base material (S) as an indentation and can be observed as the information pattern (4d). Therefore, in the precious printed matter shown in FIG. 13(a), one circular information pattern (4d) is imparted by the imprint pattern (4c) in FIG. 10(d), and since the manufacturing factory is associated as manufacturing information, it can be specified that it is a product manufactured at Factory A. Similarly, the precious printed matter shown in FIG. 13(b) can be specified as a product manufactured at Factory B, and the precious printed matter shown in FIG. 13(c) can be specified as a product manufactured at Factory C.

[0054] FIG. 14 is a view of a printed matter laminate (L) in which precious printed matters with different information patterns (4d) shown in FIGS. 12(a) to (c) are laminated in lots, observed from the side. Since the information pattern (4d) is imparted so as to cover the end portion of the base material (S), the manufacturing information can be confirmed even when observing the printed matter laminate (L) from the side. For example, when a defective product is found, it becomes possible to easily search for products with matching information patterns (4d) from the printed matter laminate (L), and the work efficiency can be improved.

[0055] The shape of the imprint pattern (4c) is not limited to these, and any shape may be used as long as it can impart an information pattern (4d) from which manufacturing information can be read when observing a lot in which a certain number of precious printed matters are laminated from the side. [[ID=IO]]

[0056] So far, one manufacturing information has been described in the form of being imparted to one location of the base material (S). However, by providing imprints (4a'') for imparting manufacturing information at a plurality of locations on the printing plate (4a), a plurality of manufacturing information may be imparted to the base material (S).

[0057] (Separation part) Figure 15 shows a side view and the mechanism of the separation unit (5) in the pasting device (1). As shown in Figure 15, the separation unit (5) is arranged downstream of the pasting unit (4), that is, on the outlet side of the pasting unit (4), and is a mechanism for separating the substrate (S) to which the foil material (H) is thermocompression bonded and the foil carrier tape (10) in the pasting unit (4). The separation unit (5) consists of at least an air nozzle (5a) and a fixture (5b) for fixing the air nozzle (5a) at an appropriate position of the pasting device (1), and the air nozzle (5a) is connected to an air duct and a pneumatic pump (both not shown).

[0058] As shown in Figure 15, the air nozzle (5a) supplies a blower that provides a laminar airflow from the direction opposite to the conveyance direction (V1) of the substrate (S) (the direction of the arrow dotted line) between the substrate (S) to which the foil material (H) is thermocompression bonded and the foil carrier tape (10). Note that the blower supplied from the air nozzle (5a) is not continuous, and in the pasting unit (4), it is supplied only for the purpose of separating the substrate (S) and the foil carrier tape (10) when the substrate (S) and the foil carrier tape (10) are thermocompression bonded and the pressure plate (4b) descends.

[0059] Figure 15(a) is a diagram showing a state in which a blower is supplied from the air nozzle (5a) toward the space between the substrate (S) being thermocompression bonded and the foil carrier tape (10). Figure 15(b) is a diagram showing a state in which the substrate (S) and the foil carrier tape (10) are separated by the supply of the blower from the air nozzle (5a), and at the same time, the gripper (3a) holds the tip (S’) of the substrate and moves in the conveyance direction (V1). Figure 15(c) is a diagram showing a state in which the gripper (3a) holds the tip (S’) of the substrate and further moves in the conveyance direction (V1) from the state of Figure 13(b).

[0060] The air nozzle (5a) is tubular and may be made of metal, resin, or other suitable material. For example, if four rows of foil carrier tape (10) are arranged in the application section (4), four air nozzles (5a) are arranged correspondingly. The amount of blower air supplied from the air nozzle (5a) is also not particularly limited, and it is preferable that the amount can be adjusted appropriately depending on the characteristics and size of the foil carrier tape (10) and substrate (S) and application conditions (pressure, temperature, time, etc.). The shape and material of the fixture (5b) for the air nozzle (5a) are also not particularly limited.

[0061] (Discharge section) As shown in Figure 3, the discharge section (6) of the bonding device (1) is equipped with at least a pile (6a) for loading the substrates (S) and a stop plate (6b). At the top of the pile (6a), the claws of the gripper (3a) holding the substrates (S) open, releasing the substrates (S), and the substrates (S) descend due to gravity, so that they are loaded one by one onto the pile (6a). Furthermore, as the number of substrates (S) loaded into the pile (6a) increases, the pile (6a) gradually descends, allowing more substrates (S) to be loaded. Although not shown, a blower, a guide, etc. may be provided as needed to properly stack the substrate (S) on the pile (6a).

[0062] As described above, according to this embodiment, by providing the marking (4a'') for providing manufacturing information on the marking plate (4a) of the pasting device (1), it is possible to easily provide manufacturing information at a position that overlaps the edge of the substrate (S), making it easy to identify the manufacturing information of defective products. Furthermore, it is possible to provide a pasting medium that allows the manufacturing information to be easily observed even when the printed matter laminate (L) is observed from the side, which contributes to improving work efficiency.
