Description

  Embodiments described herein relate generally to a transfer device that forms a thin film such as a protective film on the surface of a printing medium such as a card or a passbook.

  In recent years, printing apparatuses for cards and passbooks have been required to transfer and form a surface protective layer for protecting them on the surface of printed cards and passbooks. In other words, there are surface irregularities due to embedding of IC etc. in the card, and in the passbooks, a sufficient surface smoothness cannot be obtained unless a special surface coat is applied. There are factors that hinder it. Therefore, there is a need for a transfer method for the protective layer that allows these factors.

  One of the methods for forming a surface protective layer on a printing medium with poor surface smoothness such as a card surface with surface irregularities or paper sheets is a forming method using a transfer film. In general, a transfer film has a thin film layer such as a surface protective layer (a peeling layer or an adhesive layer if necessary) applied on a substrate. In the transfer unit, the transfer film and the print medium are sandwiched between the heat roller and the backup roller, and pressure and heat are applied to transfer the surface protective layer to the surface of the print medium on which the image is formed. Subsequently, it peels by conveying the base material of a transfer film to a different direction from the printing medium in which the protective layer was transferred in the peeling part. After the transfer, the surface protective layer is cured to protect the recorded information transferred on the print medium from fading and scraping.

  In the transfer method in the printing apparatus described above, when the surface protective layer is transferred to the surface of the print medium, an extra surface protective layer (referred to as a transfer burr) is attached around the print medium. Such a transfer burr is generated in the conveyance direction of the print medium, and is easily generated on the rear end side between the front end and the rear end in the conveyance direction.

  The transfer burr floats inside the printer body and may affect printing and printing. After transfer, excessive transfer burrs are peeled off during conveyance, and if they adhere to the roller, it causes conveyance jam. Further, if there is a transfer burr, the appearance of the print medium in the completed state is impaired. In order to keep the aesthetic appearance, it is conceivable to remove the transfer burr later, but in this case, there is a possibility that the print medium may be scratched, which causes an increase in waste.

  Considering the generation of transfer burrs, increasing the supply amount of the transfer film, for example, increasing the winding amount of the transfer film, increases the size of the apparatus, and requires a large installation area and maintenance area.

  An object of the present invention is to provide a transfer apparatus capable of preventing the occurrence of transfer burrs.

According to the embodiment, the transfer device includes a supply mechanism that transports a transfer medium having a base material and a surface protective layer provided on the base material through the transfer position, and a medium that transports the print medium through the transfer position. A transfer mechanism, a heat roller, and a backup roller facing the heat roller with a predetermined gap, and passing the transfer medium and the print medium in a state of being overlapped between the heat roller and the backup roller.

FIG. 3 is a side view schematically showing the transfer unit of the transfer device.

  As shown in FIGS. 3 and 4, a card 10 as a printing medium includes a rectangular plate-shaped card base 12 and an image 11 and print information which are transferred and formed on the upper surface of the card base. . Moreover, the card | curd base material 12 may have the peripheral edge 12a standingly arranged by the surface side along the periphery. The transfer film 14 as a transfer medium has, for example, a strip-like base material 14a made of a PET film, a surface protective layer 14b applied and formed on the base material, and an adhesive layer 14c applied and formed thereon. doing. Further, the transfer film 14 can be provided with functional layers such as a hologram layer and a fluorescent coloring layer that emits light by ultraviolet rays, and these functional layers can be transferred simultaneously with the transfer to the transfer target. When the thickness of the surface protective layer 14b is a, the thickness of the adhesive layer 14c is b, and the total thickness of the transfer film 14 is T, the height h of the peripheral edge 12a of the card substrate 12 is (a + b) < h <T.

  As shown in FIG. 5, the second transfer device 5 includes a film supply mechanism 19 that transports a transfer film 14 as a transfer medium along a predetermined transport path passing through a transfer position, and winds the transfer film after the transfer. A medium transport mechanism 41 for transporting the card 10 through the transfer position, a transfer unit 30 for superimposing the transfer film 14 on the surface of the card 10 at the transfer position, and transferring the upper surface protective layer to the card surface by pressure and heat; Thereafter, a peeling shaft 25 for peeling the transfer film 14 from the printing medium is provided at the peeling position.

  The film supply mechanism 19 includes a detachable film cassette 20 and a drive unit (not shown) that drives the cassette. The film cassette 20 includes a delivery roll 21 around which the transfer film 14 is wound, a take-up roll 22 that winds up the transferred transfer film 14, and a transfer film 14 delivered from the delivery roll 21 along a predetermined conveyance path. It has the several guide roller 24 to drive | work, and the above-mentioned peeling shaft 25 which functions as a 1st peeling mechanism. The peeling shaft 25 is formed in, for example, a cylindrical shape and is longer than the width of the transfer film 14 and the card 10. By rotating the take-up roll 22 by the driving unit, the transfer film 14 is drawn from the feed roll 21 and travels along a predetermined path. Between the guide roller 24 and the peeling shaft 25, the transfer film 14 is guided and traveled almost horizontally through the transfer position.

  The medium transport mechanism 41 that transports the card 10 through the transfer position includes guide plates 53 and 54 arranged along a horizontal transport path including the transfer position, and a plurality of transport rollers 44 and 46 that transport the card 10 therebetween. 48 and a drive mechanism (not shown) for driving the transport roller. An insertion sensor 50 that detects insertion of the card 10 and a discharge detection sensor 52 that detects discharge of the card 10 provided downstream of the transfer position are provided at the entrance of the transport path. The downstream-side transport rollers 46 and 48 are disposed between the peeling shaft 25 and the discharge detection sensor 52 and sandwich and transport the card 10 after the transfer film 14 is peeled off. Further, the medium transport mechanism 41 includes an abutting and residual detection sensor 42 provided immediately before the heat roller 26 described later.

  The guide plate 54 provided on the downstream side of the transfer position is located below the peeling shaft 25. Further, the guide plate 54 is supported so as to be rotatable around an axis orthogonal to the conveyance path, and is guided in a horizontal position along the conveyance path and is rotated clockwise to be inclined with respect to the conveyance path. It is rotated between the positioned peeling positions. A drive unit such as a motor (not shown) that rotates the guide plate 54 at a predetermined timing is provided. The guide plate 54 and the drive unit constitute a second peeling mechanism 60.

  As shown in FIG. 5, the transfer unit 30 has a metallic heat roller 26 provided on one side of a horizontal film conveyance path between the guide roller 24 and the peeling shaft 25, and a film conveyance path. A backup roller 28 disposed opposite to the heat roller 26, an elevating mechanism 144 that moves the heat roller 26 up and down, and a pressing mechanism 37 that biases the backup roller 28 toward the heat roller are provided.

  The lifting mechanism 144 includes a swing arm 31 that supports the heat roller 26, a tension spring 32 that biases the swing arm 31 in a direction in which the heat roller 26 moves away from the transport path, and a direction in which the heat roller 26 approaches the transport path. A cam 34 that presses the swing arm 31 and a drive motor (not shown) that drives the cam are provided. By rotating this cam, the swing arm 31 rotates and the heat roller 26 moves up and down.

  The pressing mechanism 37 includes a swing arm 33 that supports the backup roller 28, a compression spring 40 that presses the swing arm 33 in a direction in which the backup roller 28 approaches the conveyance path, that is, a direction in which the backup roller 28 approaches the heat roller 26, and a spring support. 45 and an inter-roller gap adjusting mechanism 38.

  As shown in FIGS. 6 and 7, the heat roller 26 includes a heater 27 therein, and a silicone rubber 26a is wound around the roller surface. The thickness of the silicon rubber 26a is preferably about 1 to 3 mm, and the rubber hardness is preferably 20 to 50 °. Rubber thickness affects thermal conductivity. If it is thin, heat is easily transmitted, but it is easily damaged. Increasing the thickness of the rubber slightly increases the durability, but worsens the heat transfer. In this case, it is possible to increase thermal conductivity by arranging fine carbon fibers in the radial direction. The hardness of the silicon rubber 26a affects the edge effect and the heat roller life.

  A rubber 28 a is wound around the surface of the backup roller 28. Silicon rubber having a rubber thickness of about 1 to 2 mm and a hardness of 80 to 90 ° is used. When the thickness of the silicon rubber is thick and the hardness is low, it is difficult to apply pressure and the life is shortened. Silicone rubber is desirable because of its characteristics, because it is resistant to chemical changes and the state of the rubber hardly changes even if a surface protective layer adheres to the surface.

  As shown in FIG. 7, when the thickness of the card 10 is S, the gap (gap g) between the heat roller 26 and the backup roller 28 is set to g <(S / 2). By setting such a gap g, when the card 10 is inserted between the heat roller 26 and the backup roller 28, the front end of the card is abutted against the heat roller 26 to prevent a transfer burr generated at the front end. When the leading edge of the card 10 bites into the transfer film by the pressure of the backup roller 28, the surface protective layer is cut off easily, and transfer burr hardly occurs even if it is peeled off as it is.

  As shown in FIG. 8, the backup roller 28 may be a metal material without winding rubber around the conveyance surface. In this case, the surface roughness of the roller is 0.6 to 6.3 μm or less, for example, 1.6 μm, as an average roughness. If the surface roughness is too low (too slippery), slippage may occur between the card 10 and the backup roller 28 during transport, which may cause transport jam.

  When the backup roller 28 is made of metal, it is easy to clean the roller, and it is possible to eliminate the need for periodic replacement of the backup roller. Further, it is more effective against slipping if a driving force is given to the heat roller 26 side. It is desirable to take the power source from the same location so that there is no speed difference.

  When the rollers 26 and 28 are driven separately by the drive motor 57, the speed difference at that time is preferably within 3%. A speed difference of more than that affects the conveyance, and is liable to cause transfer defects, voids, and wrinkles. If the thickness of the transfer film 14 increases, the heat roller 26 side can also be made of metal. When the transfer film 14 becomes thick, the transfer film itself has a role of rubber, and the heat roller 26 can be metalized.

  The roller surface roughness at this time is preferably 1.6 μm or less so as not to create scratches on the transfer film 14. Since the heat roller 26 is also metalized, it is not necessary to replace both rollers regularly, and the life cycle cost can be reduced. In addition, since there is no rubber on the surface, heat transfer efficiency is increased, power consumption is reduced, and an environment-friendly device can be obtained.

Next, the transfer operation of the second transfer device 5 configured as described above will be described.
As shown in FIG. 5, when the card 10 is sent from the upstream unit, the medium transport mechanism 41 receives the card and transports the card 10 substantially horizontally in the transport direction B through the transfer position. That is, when the insertion sensor 50 detects the leading edge of the card 10, the medium transport mechanism 41 rotates the transport rollers 44 and 46 to transport the card 10 in the transport direction B. At almost the same time, the transfer film 14 is supplied along the transport path by the film supply mechanism 19 and sequentially superposed on the upper surface of the card 10.

  When the front end of the card 10 is detected by the abutment / residual detection sensor 42, the heat roller 26 is lowered by the cam 34 and the front end of the card is abutted against the heat roller. At this time, the backup roller 28 does not particularly move up and down. When the leading edge of the card 10 is abutted against the heat roller 26, transfer is started.

  The card 10 and the transfer film 14 superimposed on the upper surface thereof are inserted into the gap g between the heat roller 26 and the backup roller 28, and are sandwiched and conveyed by these rollers. At the same time, the transfer film 14 is also wound on the winding roll 22 with a constant tension. At this time, heat is applied from the heat roller 26 and pressure is applied from the backup roller 28 to the transfer film 14 and the card 10, and the transfer film 14 and the card 10 are brought into close contact with each other, whereby the surface protective layer 14b on the transfer film 14 is attached. Move to the card surface. At this time, as shown in FIG. 4, since the edge 12a is erected along the peripheral edge of the card base, the edge 12a bites into the upper surface protective layer 14b transferred onto the surface of the card 10 to protect the upper surface. The layer is divided along the edge 12 a, that is, along the outer peripheral edge of the card 10. Thus, when the transfer film 14 is peeled from the card 10, the upper surface protective layer 14b is easily cut along the outer peripheral edge of the card 10 to suppress the generation of transfer burrs.

  Subsequently, the transfer film 14 is peeled from the leading end side in the transport direction of the card 10 by the peeling shaft 25 provided in the film cassette 20 and guided to the winding roll 22 side. The card 10 is conveyed in the conveyance direction B as it is, and when the leading edge of the card is detected by the discharge detection sensor 52, the heat roller 26 is pushed up to a position away from the conveyance path and the transfer film 14. The conveyance of the card 10 and the winding of the transfer film 14 are continued. Immediately before the discharge detection sensor 52, conveyance rollers 46 and 48 are installed, and the card 10 is not carried to the transfer film 14 by sandwiching the card 10 by these rollers.

  In addition, after the transfer film 14 starts to be peeled from the front end side of the card 10, as shown in FIGS. 9 and 10, the guide plate 54 of the second peeling mechanism 60 is moved from the horizontal guide position shown in FIG. Rotate in the range of 5 to 30 degrees in the direction, and move to the peeling position facing diagonally upward left as shown in FIG. At this time, since the transfer film 14 is stretched with a predetermined tension, the upper surface protective layer 14b is moved to the rear end of the card 10 by rotating the rear end of the card 10 away from the transfer film 14 by the guide plate 54. And is separated from the transfer film 14. This prevents a transfer burr from occurring on the card rear end side.

Thereafter, the guide plate 54 is returned to the guide position, and the conveyance of the card 10 and the winding of the transfer film 14 are continued. When the rear end of the card 10 is detected by the discharge detection sensor 52, only the card 10 is conveyed to the next unit, and the winding of the transfer film 14 is stopped.
When the next card 10 enters the second transfer device 5, the above transfer operation is repeated.

According to the second transfer device 5 configured as described above, the second peeling mechanism 60 is provided, the upper surface protective layer 14b is divided along the rear end of the card, and the upper surface protective layer is peeled off from the transfer film, Generation of transfer burrs on the card rear end side can be reliably prevented. Moreover, the gap between the heat roller and the backup roller is made smaller than the thickness of the card, and the card tip is brought into contact with the heat roller when the card is inserted, thereby preventing the occurrence of transfer burr on the card tip side. . Furthermore, by raising the edge along the outer peripheral edge of the card base, the card edge bites into the transfer film by the pressure of the backup roller, so that the surface protective layer is cut off, and even if it is peeled off, burrs will be generated. It is possible to make it difficult to occur.
From the above, a transfer device capable of preventing the occurrence of transfer burrs without increasing the size of the device can be obtained.

  Next, a transfer device according to another embodiment will be described. In the various embodiments described below, the same parts as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted, and the parts different from those in the first embodiment. Will be described in detail.

It is set as the state which moved to the peeling position which turned to the right diagonally downward. At this time, since the transfer film 14 is stretched with a predetermined tension, the upper surface of the transfer film 14 is protected by rotating the rear end of the card 10 away from the transfer film 14 by the rotation plate 44. The layer 14b is divided along the rear end of the card and peeled off from the transfer film 14. This prevents a transfer burr from occurring on the card rear end side. Thereafter, the rotating plate 55 is returned to the guide position, and the conveyance of the card 10 and the winding of the transfer film 14 are continued. When the trailing edge of the card 10 is detected by the discharge detection sensor described above, only the card 10 is conveyed to the next unit, and the winding of the transfer film 14 is stopped.

  According to the present embodiment, the second peeling mechanism 60 moves up and down the fixed shaft 61 and the movable shaft 62 provided between the heat roller 26 and the guide plate 54 on the downstream side of the transfer unit 30 and the movable shaft 62. And a drive unit (not shown). The fixed shaft 61 and the movable shaft 62 are arranged above and below the conveyance path, that is, across the transfer film 14 and the card 10 and also serve as a card conveyance guide. The movable shaft 62 is supported from the lower position of the conveyance path so as to be movable upward across the conveyance path, that is, movable toward the fixed shaft 61 side.

The second peeling shaft 64 is in a positional relationship that does not interfere even when the heat roller 26 is lowered to the transfer position.

  In the transfer operation of the transfer device 5, when the leading end of the card 10 is detected by the discharge detection sensor, the heat roller 26 is moved upward from the transfer position. The card 10 and the transfer film 14 are conveyed to the peeling shaft 25 in a transferred state (overlapped state). After this transfer, during transfer, the tension of the transfer film 14 becomes weaker by about 10 to 20% than usual. And when the front-end | tip of the card | curd 10 passes the peeling shaft 25, the tension | tensile_strength of the transfer film 14 is returned.
