Description

  The present invention relates to a direct foil printing apparatus for directly transferring a hot stamp foil to a transfer material by heat generated by a thermal head.

  Conventionally, foil stamping (hot stamping) has been known as a method for transferring foil onto a material to be transferred. In this method, a hot stamp foil composed of a base film, a release layer, a colored layer, a vapor deposition layer, and an adhesive layer is thermocompression bonded with a dedicated metal mold in which a desired pattern has been formed in advance, thereby releasing a mold other than the base film. In this method, a foil layer composed of a layer, a colored layer, a vapor deposition layer, and an adhesive layer is softened and the foil is transferred to a transfer material (see Patent Document 1). Also known is a hot stamping method in which a foil other than the desired pattern is extracted from a hot stamp foil by a thermal head, and a foil is transferred to the material to be transferred using a foil ribbon. (See Patent Document 2).

  However, in the conventional foil stamping, since foil transfer is performed by thermocompression bonding with a dedicated mold, not only the apparatus itself becomes large, but also a separate mold is required due to the difference in printing pattern, and the cost It takes.

  On the other hand, although the hot stamping method of Patent Document 2 requires two steps of transfer foil preparation and foil transfer, there is an advantage that uniform foil transfer can be realized with an inexpensive mechanism and technology. However, in this method, since foil other than the desired pattern is extracted from the hot stamp foil, the printing rate is opposite to that in normal printing, and the printing rate in normal printing is 10 to 15%. The printing rate is 85 to 90%. For this reason, particularly when the transfer foil is continuously formed, an overheating phenomenon of the thermal head occurs, and this causes a phenomenon such as extracting a foil of a desired pattern or more. As a result, characters and figures formed with the transfer foil become unclear.

  Therefore, the present inventors, regardless of conventional common sense, use a thermal head, which is a technology in a field completely different from foil stamping, to directly transfer the foil of the desired pattern portion of the hot stamp foil to the transfer material. The inventors found that transfer is possible, and filed an invention of a direct foil printing apparatus for hot stamping foil (see Patent Document 3). This direct foil printing apparatus directly transfers a foil of a desired pattern portion of a hot stamp foil to a transfer material, and uniform foil transfer for each product can be realized by an inexpensive mechanism and technology in one process. Moreover, when the present apparatus is used for producing a transfer foil by the hot stamping method, the foil can be removed without a dedicated foil removing ribbon by transferring the foil to an inexpensive transfer material for foil removing.

  In order to put the direct foil printing apparatus described above into practical use, the present inventors have conducted various studies. As a result, it was concluded that in order to perform stable and high-quality printing, it is important to firmly hold the foil against the transfer material near the thermal head. On the other hand, the direct foil printing machine is provided with several motors as a drive source. Since these motors account for a large percentage of the cost of the machine, the number of motors can be minimized to reduce costs. We also examined whether to limit. As a result, it was found that the motor can be omitted by devising the foil feeding mechanism.

  The present invention has been created under the background described above, and the problem is that stable high-quality printing can be performed, and the number of motors can be reduced and realized at low cost. It is to provide a possible direct foil printing apparatus.

The direct foil printing apparatus according to the present invention includes a first motor, a slide member that moves forward or backward in the first direction by the rotation of the first motor, a second motor connected to the slide member, and a slide member. And a head unit that is connected and moves in a second direction perpendicular to the first direction by rotation of the second motor. The head unit includes a thermal head, a foil supply roller around which a hot stamp foil transferred to a transfer material by the thermal head is wound, and a foil that winds up the hot stamp foil supplied from the foil supply roller and transferred. A winding roller, a foil pressing roller for pressing the hot stamp foil from the foil supply roller to the foil winding roller against the material to be transferred , a thermal head and a foil pressing roller are attached via springs, respectively. And an attachment member that moves in the second direction by rotation. The head unit moves in the second direction due to the rotation of the second motor. After the thermal head and the foil pressing roller abut on the material to be transferred, the mounting member further moves in the second direction by continuing the rotation of the second motor. As a result of the compression of the spring, the foil pressing roller presses the hot stamp foil against the transfer material with a constant pressure. Then, the foil pressing roller rotates in conjunction with the movement of the head unit by moving the head unit while the hot stamp foil is pressed against the material to be transferred by the foil pressing roller, and this foil pressing roller rotates. Thus, the hot stamp foil is sent from the foil supply roller to the foil take-up roller.

  In such a direct foil printing apparatus, the foil pressing roller presses the hot stamp foil from the foil supply roller to the foil take-up roller against the material to be transferred, so that the hot stamp foil becomes the material to be transferred near the thermal head. On the other hand, the hot-stamp foil is not brought into a floating state, and heat transfer can be performed with the hot stamp foil securely adhered to the transfer material. For this reason, the transfer is performed stably, and the quality of the transferred characters and the like is improved. When the head unit is moved while the hot stamping foil is pressed against the material to be transferred by the foil pressing roller, the foil pressing roller rotates in conjunction with this movement, and the friction between the foil pressing roller and the hot stamping foil. Therefore, the hot stamping foil is fed to the winding side with the rotation of the foil pressing roller. Therefore, a motor for driving the foil pressing roller can be omitted.

  In a preferred embodiment of the present invention, an anti-slip sheet is provided on the upper surface of the support portion on which the transfer material is placed. According to this, even if the foil pressing roller rotates in conjunction with the movement of the head unit, the material to be transferred is prevented from moving by the anti-slip sheet, and only the hot stamp foil is fed by the foil pressing roller. Transfer failure to the material does not occur, and transfer can be performed reliably.

  In a preferred embodiment of the present invention, the hot stamp foil that has passed through the thermal head is peeled from the transfer material between the thermal head and the foil pressing roller located on the winding side with respect to the thermal head. A foil peeling mechanism that leads to the foil pressing roller is provided. According to this, since the timing at which the hot stamping foil is peeled off from the transfer material can be set optimally, an excess foil layer of a portion other than the desired pattern is transferred, or transfer of the foil layer of the desired pattern portion is not performed. The image quality of characters and figures formed on the transfer material can be improved without becoming complete.

  According to the present invention, a hot stamping foil can be brought into close contact with a transfer material by a foil pressing roller, and stable high-quality printing can be performed, and a motor for driving the foil pressing roller becomes unnecessary. An inexpensive direct foil printing apparatus can be realized at a reduced cost.

And according to the rotation direction of the lead screw 22, the elevating member 23 moves in the direction of the arrow (vertical direction). At this time, the elevating member 23 moves while being guided by a guide portion (not shown). As a result, the head unit 20 connected to the elevating member 23 moves in the vertical direction (second direction) .

The hot stamping foil 40 wound around the foil supply roller 35 is rewound and is sequentially wound around the foil winding roller 36 via the foil pressing roller 31, the thermal head 30, and the foil pressing roller 32. A section 25 for detecting the vertical position of the unit is provided at the upper part of the head unit 20, and the second sensor 26 made of a photosensor detects this section 25. The second sensor 26 is provided on the attachment member 15.

The anti-slip sheet 52 has a very strong frictional force on the upper surface in the horizontal direction, and is a plate-like body placed on the sheet 52 (in the case of the present invention, a transfer material 53 to be described later). ) Is prevented from moving in the horizontal direction, while it can be easily peeled off by turning the plate-like body. As such an anti-slip sheet 52, for example, “FIX FILM” (registered trademark) manufactured by Fujiko Pian Co., Ltd. can be used.

  In the direct foil printing apparatus A described above, the first motor 11, the lead screw 12 and the slide member 13 constitute one embodiment of the first driving means in the present invention, and the second motor 21, the lead screw 22 and the elevating member. 23 constitutes an embodiment of the second driving means in the present invention, and the fixing base 50 and the mounting base 51 constitute a support part in the present invention. In the normal state, the head unit 20 is in the raised position with respect to the lead screw 22 and is spaced apart from the anti-slip sheet 52 by a certain distance.

  FIG. 2 shows a cross-sectional view of the hot stamp foil 40. The hot stamp foil 40 has a long band shape, and includes a base layer 41 and a foil layer 42. The base layer 41 is made of, for example, a polyethylene terephthal (PET) or polypropylene (PP) film. The foil layer 42 includes, for example, a release layer made of acrylic resin or cellulose resin, a colored layer made of resin of the same system as general ink, a vapor deposition layer made of a thin metal film layer, an adhesive layer made of acrylic or PET, etc. It consists of a laminated structure. The base layer 41 is a portion that remains without being transferred to the transfer material, and the foil layer 42 is a portion that is transferred from the base layer 41 to the transfer material. In FIG. 1, the base layer 41 faces the thermal head 30, and the foil layer 42 faces the anti-slip sheet 52.

  FIG. 3 shows an electrical block diagram of the direct foil printing apparatus A described above. Reference numeral 1 denotes a control unit that controls the entire apparatus, and includes a CPU, a memory, and the like. Reference numeral 11 denotes a first motor for conveyance, and reference numeral 21 denotes a second motor for lifting, which are the same as those shown in FIG. Reference numeral 37 denotes a winding motor for rotating the foil winding roller 36, which is not shown in FIG. 1 but is attached to the head unit 20. Reference numeral 30 is a thermal head, 34 is a first sensor, 26 is a second sensor, and 17 is a third sensor, which are the same as those shown in FIG. Reference numeral 2 denotes a host device connected to the direct foil printing apparatus A, which is composed of, for example, a personal computer and includes an input unit, a storage unit, a control unit, and a display unit. In the host device 2, a foil pattern (characters, figures, etc.) to be transferred to the transfer material is created, and the data is sent to the direct foil printing device A.

  Next, the procedure in the case of performing foil transfer by the direct foil printing apparatus A will be described with reference to FIGS. First, the host device 2 creates a print pattern to be transferred, and sets a print start position, a print end position, a print speed, and the like. When these preparations are completed, the transfer material 53 is placed on the anti-slip sheet 52 fixed to the mounting base 51 as shown in FIG. Here, the size of the transfer material 53 is the same as the size of the anti-slip sheet 52 (for example, A4). The transfer material 53 is positioned by a strong horizontal frictional force of the anti-slip sheet 52. Subsequently, a printing start command is given from the host apparatus 2 to the direct foil printing apparatus A.

  When a printing start command is given to the direct foil printing apparatus A, the first motor 11 for conveyance rotates in the forward direction, and the lead screw 12 rotates in the forward direction at the same time. 12) until the print start position shown in FIG. 4 is reached. As a result, the second motor 21 attached to the attachment member 15 and the head unit 20 coupled to the lead screw 22 of the second motor 21 also move to the right.

  When the head unit 20 moves to the printing start position, the rotation of the first motor 11 stops, the head unit 20 stops once, and instead, the second motor 21 rotates in the forward direction. At the same time, since the lead screw 22 rotates in the forward direction, as shown in FIG. 5, the elevating member 23 moves downward, and the head unit 20 descends from the raised position. When the head unit 20 is lowered by a certain amount, the thermal head 30 and the foil pressing rollers 31 and 32 come into contact with the transfer material 53 via the hot stamp foil 40.

  Even after the thermal head 30 and the foil pressing rollers 31 and 32 abut on the transfer material 53, the second motor 21 continues to rotate, and the elevating member 23 moves further downward as shown in FIG. In this case, the positions of the rollers 31, 32, 35, and 36 do not change, but only the attachment member 24 moves downward in conjunction with the elevating member 23. Therefore, the springs 27 to 29 are compressed and contracted by the mounting member 24, and the thermal head 30 and the foil pressing rollers 31 and 32 press the hot stamp foil 40 against the transfer material 53 with a constant pressure. At this time, the first sensor 34 descending together with the mounting member 24 detects the segment 33.

  When the first sensor 34 detects the segment 33, the second motor 21 continues to rotate until a certain time has elapsed from that point. For this reason, as shown in FIG. 7, the elevating member 23 and the mounting member 24 move further downward, and the springs 27 to 29 are further compressed by the mounting member 24, so that the thermal head 30 and the foil pressing rollers 31, 32 Sufficient pressing force is secured.

  After the first sensor 34 detects the segment 33, the second motor 21 stops rotating when a certain time has elapsed, and instead, the first motor 11 rotates in the forward direction again. Therefore, the lead screw 12 rotates in the forward direction, and as shown in FIG. 8, the head unit 20 moves to the right together with the slide member 13 from the print start position (FIG. 7) to the print end position (FIG. 9). Moving. In this case, since the foil pressing rollers 31 and 32 are pressed against the transfer material 53 via the hot stamp foil 40 by the springs 28 and 29, the foil pressing rollers 31 and 32 are moved in the arrow direction in conjunction with the movement of the head unit 20 in the right direction. Rotate.

  When the foil pressing rollers 31 and 32 rotate, the hot stamping foil 40 is fed from the foil supply roller 35 side to the foil winding roller 36 side due to friction between these rollers and the hot stamping foil 40. That is, the foil supply roller 35 rotates in the direction of the arrow to feed the hot stamp foil 40, and the fed foil 40 is fed by the foil pressing rollers 31 and 32 and rotated by the winding motor 37 (FIG. 3). The foil winding roller 36 is wound up. In this process, the thermal head 30 is energized, and the heating element built in the thermal head 30 generates heat according to the printing pattern, whereby the foil layer 42 (see FIG. 2) is transferred to the transfer material 53. As a result, predetermined characters and figures are printed on the surface of the transfer material 53.

  When the head unit 20 reaches the print end position shown in FIG. 9, the first motor 11 stops rotating, the head unit 20 stops, and instead, the second motor 21 rotates in the reverse direction. At the same time, the lead screw 22 rotates in the opposite direction, so that the elevating member 23 moves upward as shown in FIG. When the head unit 20 is raised, the second sensor 26 detects the section 25 provided at the upper part of the unit.

  When the second sensor 26 detects the segment 25, the second motor 21 stops rotating, the head unit 20 stops at the raised position, and instead the first motor 11 rotates in the reverse direction. At the same time, the lead screw 12 rotates in the opposite direction, so that the head unit 20 moves to the left along with the slide member 13 while being separated from the transfer material 53 as shown in FIG. Then, when the head unit 20 returns to the initial position shown in FIG. 12, the third sensor 17 detects the section 16, the first motor 11 stops, and the head unit 20 stops.

  Thus, the foil transfer by one scan of the head unit 20 is completed. When the size of the print pattern transferred to the transfer material 53 is larger than the heat generation area of the thermal head 30 and the foil transfer is not completed by one scan, the electric slider 10 is perpendicular to the paper surface by a drive mechanism (not shown). After moving in the direction, the first motor 11 and the second motor 21 may be controlled according to the same procedure as described above, and foil transfer may be performed by a plurality of scans.

  When a predetermined printing pattern is formed on the transfer material 53 in this way, the direct foil printing apparatus A receives a printing end command from the host apparatus 2 and stops its operation. Thereafter, the transfer material 53 is peeled off from the non-slip sheet 52 and taken out, and a series of operations is completed.

  FIG. 13 is a flowchart showing the procedure described above. This procedure is executed by the CPU provided in the control unit 1 of the direct foil printing apparatus A. When a print start command is given from the host device 2 in step S1, the first motor 11 is rotated forward to advance the head unit 20 (step S2), and when the head unit 20 reaches the print start position (step S3), The rotation of the first motor 11 is stopped (step S4). Subsequently, the second motor 21 is rotated forward to lower the head unit 20 (step S5), and when the first sensor 34 detects the segment 33 (step S6), it waits for a certain period of time to elapse (step S6). Step S7) When the predetermined time has elapsed, the rotation of the second motor 21 is stopped (Step S8).

  Next, the first motor 11 is rotated forward again to advance the head unit 20 (step S9), and the hot head foil 40 is fed by the rotation of the foil pressing rollers 31 and 32, and the thermal head 30 is energized to perform hot stamping. The foil 40 is transferred from the foil 40 to the transfer material 53, and the winding motor 37 is driven to wind the hot stamp foil 40 after transfer by the foil winding roller 36 (step S10). When the head unit 20 moves to the printing end position (step S11), the first motor 11 is stopped (step S12).

  Subsequently, the second motor 21 is reversely rotated to raise the head unit 20 (step S13). When the second sensor 26 detects the segment 25 (step S14), the rotation of the second motor 21 is stopped (step S15). Then, the first motor 11 is reversely rotated to retract the head unit 20 (step S16). When the head unit 20 returns to the initial position and the third sensor 17 detects the slice 16 (step S17), the rotation of the first motor 11 is performed. Is stopped (step S18), and the operation for one scan is completed. When scanning is performed a plurality of times, the procedure of FIG. 13 is repeatedly executed by the number of times of scanning. In this case, instead of returning the head unit 20 to the initial position, it may be returned to the next print start position. Thereby, the printing time can be shortened.

  Thus, according to the direct foil printing apparatus A of the first embodiment, the foil pressing rollers 31 and 32 press the hot stamp foil 40 against the transfer material 53 on both sides of the thermal head 30, so that the thermal head The hot stamp foil 40 does not float from the transfer material 53 near 30, and the hot stamp foil 40 can be securely adhered to the transfer material 53 for thermal transfer. For this reason, foil transfer is performed stably and the quality of the printing pattern formed by transfer is also improved. Further, when the head unit 20 is conveyed while the hot stamp foil 40 is pressed against the transfer material 53 by the foil pressing rollers 31 and 32, the foil pressing rollers 31 and 32 rotate in conjunction with the conveyance, and the foil pressing is performed. Due to the friction between the rollers 31 and 32 and the hot stamping foil 40, the hot stamping foil 40 is sent to the winding side along with the rotation of the foil pressing rollers 31 and 32.

  Originally, when the foil pressing rollers 31 and 32 are provided to press the hot stamping foil 40, the hot stamping foil 40 is sandwiched between these rollers and the material to be transferred 53. If the motor 32 is not rotated by a motor, the hot stamping foil 40 cannot be wound only by the rotation of the foil winding roller 36. However, in this embodiment, the foil pressing rollers 31 and 32 are interlocked with the movement of the head unit 20. Since it rotates, the drive source which rotates the foil pressing rollers 31 and 32 becomes unnecessary, and the motor for driving these rollers can be omitted, and the cost can be reduced.

  Further, since the non-slip sheet 52 is provided on the mounting base 51 on which the transfer material 53 is placed, the transfer material is not affected even when the head unit 20 moves and the foil pressing rollers 31 and 32 rotate. 53 is prevented from moving by the strong frictional force in the horizontal direction of the non-slip sheet 52, and only the hot stamp foil 40 is fed by the foil pressing rollers 31, 32, so that transfer failure to the transfer material 53 does not occur. The foil transfer can be performed reliably.

FIG. 14 is an enlarged view of a main part of a direct foil printer according to the second embodiment of the present invention, and shows a configuration near the thermal head. Here, a foil peeling mechanism including a foil peeling bar 38 and a foil peeling roller 39 is provided between the thermal head 30 and the foil pressing roller 32 positioned on the winding side with respect to the thermal head 30. Other configurations are the same as those in the first embodiment . The foil peeling bar 38 is a J-shaped bar fixed to the thermal head 30. The foil peeling bar 38 may have another shape such as an L shape or an S shape. The foil peeling roller 39 is attached to, for example, the tip of an arm (not shown) that is swingably supported by the attachment member 24. The hot stamping foil 40 that has passed through the thermal head 30 is peeled off from the transfer material 53 at the lower end position of the foil peeling bar 38, and is guided to the foil pressing roller 32 while being separated from the transfer material 53 by the foil peeling roller 39.

  If such a foil peeling mechanism is not provided, the hot stamp foil 40 having the desired pattern of the foil layer 42 (FIG. 2) transferred to the transfer material 53 by the thermal head 30 is not covered for the first time at the position of the foil pressing roller 32. It peels from the transfer material 53. However, since there is a distance from the thermal head 30 to the foil pressing roller 32, the adhesive layer of the hot stamp foil 40 heated and softened by the thermal head 30 is cooled and hardened before reaching the foil pressing roller 32. For this reason, the adhesive force between the hot stamp foil 40 and the material to be transferred 53 becomes too strong, and when the hot stamp foil 40 is peeled off from the material to be transferred 53 at the portion of the foil pressing roller 32, the foil layer of the desired pattern portion. In addition, the surrounding foil layer remains adhered to the transfer material 53, resulting in a problem that characters and figures formed on the transfer material 53 become unclear and image quality deteriorates. On the other hand, if the hot stamp foil 40 is peeled off immediately after being heated by the thermal head 30, the adhesive layer of the hot stamp foil 40 is in a softened state and the foil layer is not sufficiently bonded to the transfer material 53. The foil layer of the pattern portion is not completely transferred to the transfer material 53, and characters and figures become unclear and the image quality deteriorates. That is, the timing at which the hot stamp foil 40 is peeled from the transfer material 53 after the thermal transfer by the thermal head 30 is important, and this timing must not be too early or too late.

  Therefore, as shown in FIG. 14, a foil peeling mechanism including a foil peeling bar 38 and a foil peeling roller 39 is provided between the thermal head 30 and the foil pressing roller 32, and the hot stamp foil 40 is separated from the thermal head 30 by a certain distance. The hot stamping foil 40 is peeled off from the transfer material 53 if it is peeled off at the lower end position of the separated foil peeling bar 38 and guided to the foil pressing roller 32 in a state separated from the transfer material 53 by the foil peeling roller 39. The timing can be set optimally. As a result, the excess foil layer of the portion other than the desired pattern is not transferred, and the transfer of the foil layer of the desired pattern portion is not incomplete, and the characters and figures formed on the transfer material 53 are clear. Therefore, the image quality can be improved.

  In the present invention, various embodiments other than those described above can be adopted. For example, in the first embodiment, after the first sensor 34 detects the section 33, the elevating member 23 is lowered until a certain time elapses, and the conveyance of the head unit 20 is started when the certain time elapses. Depending on the positional relationship between the first sensor 34 and the section 33, the conveyance of the head unit 20 may be started when the first sensor 34 detects the section 33. In the first embodiment, the winding motor 37 for driving the foil winding roller 36 is provided. However, a mechanism is employed in which the foil winding roller 36 rotates in conjunction with the foil pressing roller 32. Thus, the winding motor 37 may be omitted. Furthermore, in the first embodiment, an example in which the mounting base 51 is provided on the fixing base 50 and the non-slip sheet 52 is fixed to the mounting base 51 has been described. However, the mounting base 51 is omitted and the fixing base 50 is omitted. The anti-slip sheet 52 may be directly fixed.

  In the first embodiment, since the anti-slip sheet 52 and the material to be transferred 53 have the same size, the transfer material 53 is placed directly on the anti-slip sheet 52. When the size of the sheet for printing is A4 and the material to be transferred is the size of a postcard or business card, an A4 size frame-shaped spacer having a hollow corresponding to the size is placed on the anti-slip sheet. Then, the transfer material may be fitted into the hole of the spacer to perform foil transfer. In this case, since the anti-slip sheet around the transfer material is covered with the spacer, the foil pressing roller and the anti-slip sheet are not in direct contact with each other when the head unit moves, and the anti-slip sheet friction is prevented. It is possible to avoid hindering the rotation of the foil pressing roller due to the force.

In the first embodiment, the horizontal direct foil printing apparatus in which the fixing base 50 is installed horizontally is taken as an example. However, the present invention is also applied to a vertical direct foil printing apparatus in which the fixing base 50 is installed vertically. Is possible. In the case of the vertical type, the direct foil printing apparatus A in FIG. 1 is rotated 90 degrees, and the slide member 13 is in the vertical direction (first direction) and the elevating member 23 is in the horizontal direction (second direction) . Moving. In the first embodiment, the host device 2 is provided separately from the direct foil printing device, but the function of the host device 2 may be provided on the direct foil printing device side.

  Moreover, in FIG. 14, although the example which comprised the foil peeling mechanism by the foil peeling bar 38 and the foil peeling roller 39 was given, the foil peeling mechanism of this invention is not limited to this. For example, a roller is used in place of the foil peeling bar 38 and a foil peeling mechanism is configured by two foil peeling rollers, or conversely, a bar is used in place of the foil peeling roller 39 and two foil peeling bars are used. It is also possible to configure a foil peeling mechanism.
