1. Technical Field
The present invention relates to a label preparing device which prepares a printed label by performing laser cutting and applying ink to a media, and a label preparing method in the label preparing device.
2. Related Art
In the related art, a label manufacturing device (refer to JP-A-2003-226313) is known which includes a laser cutting mechanism that forms a cutting line which is the outline of a label on a label connection body by irradiating the label connection body with laser beams, and a thermal head that performs printing on the label connection body.
The inventors found the problem below.
When the label preparing device forms a cutting line by irradiating a media with laser beams, inclined surfaces (hereinafter, referred to as a “peripheral inclined surfaces”), which have an approximately “V” sectional shape that is open toward a laser beam radiation side, are formed on both the sides of the cutting line on the media due to the intensity distribution of laser beams. When the label preparing device performs laser cutting after applying ink to the media, ink is not applied to the peripheral inclined surfaces. Therefore, it is difficult for the label preparing device to prepare a label piece which has colored peripheral parts.
An advantage of some aspects of the invention is to provide a label preparing device which is capable of preparing a label piece which has colored peripheral parts, and a label preparing method in the label preparing device.
According to an aspect of the invention, there is provided a label preparing device including: a laser cutting section that forms a cutting line, which is an outline of a label piece, on a media by irradiating the media with laser beams; and a print section that applies ink to at least a peripheral part of the label piece after the cutting line is formed.
According to another aspect of the invention, there is provided a label preparing method in a label preparing device including: forming a cutting line, which is an outline of a label piece, on a media by irradiating the media with laser beams; and applying ink to at least a peripheral part of the label piece after the cutting line is formed.
According to the aspect of the invention, the label preparing device applies ink to the peripheral parts of the label piece, that is, the peripheral inclined surfaces which are formed through laser irradiation after the cutting line is formed. Therefore, peripheral inclined surfaces are colored by ink. Accordingly, it is possible for the label preparing device to prepare the label piece in which the peripheral parts are colored.
In the label preparing device, it is preferable that the laser cutting section irradiates the media in an immobile state with laser beams, and the print section applies ink to the media in which the immobile state is maintained.
According to the aspect of the invention, the label preparing device applies ink to the media in an immobile state after laser cutting is performed on the media in the immobile state. Therefore, it is possible for the label preparing device to appropriately apply ink to the peripheral parts of the label piece without detecting a position where the label piece is formed.
In this case, it is preferable that the label preparing device further includes a platen on which the media in the immobile state is placed, in which the laser cutting section forms the cutting line on the media, which includes a label connection body and a liner which is affixed to the label connection body, such that the label connection body is cut and the liner is not cut.
According to the aspect of the invention, laser beams are prevented from passing through the media and being irradiated to the platen. Therefore, it is possible for the label preparing device to prevent the platen from being damaged when the media is irradiated with laser beams.
In this case, it is preferable that the label preparing device further includes a data acquisition unit that acquires print data; and a print data processing unit that processes the print data such that a print density of the peripheral part of the label piece increases, in which the print section applies ink to the media based on the processed print data.
If the label preparing device applies ink according to original print data when the peripheral inclined surfaces, which are formed through laser irradiation, have bad placement of ink compared to the print surface of the media, the print density of the peripheral inclined surfaces, that is, the peripheral parts of the label piece is lower than an assumed density.
In contrast, according to the aspect of the invention, the label preparing device applies ink to the media based on the print data which is processed such that the print density of the peripheral parts of the label piece increases. Therefore, even when the peripheral inclined surfaces have bad placement of ink compared to the print surface of the media, it is possible for the label preparing device to color the peripheral parts of the label piece at an appropriate print density.
In this case, it is preferable that the print section applies pre-coating liquid for forming a pre-coated layer, which accommodates ink, to at least the peripheral part of the label piece after the label piece is formed by the laser cutting section and before ink is applied to the media.
When the label preparing device performs laser cutting on the media on which the pre-coated layer is formed, the pre-coated layer is removed from the peripheral inclined surfaces, which are formed through laser irradiation, that is, the peripheral parts of the label piece. Therefore, the label preparing device applies ink to the peripheral parts of the label piece in a state in which the pre-coated layer is not present. Since an area, in which the pre-coated layer is not present, has bad placement of ink, the peripheral parts of the label piece are not appropriately colored.
In contrast, according to the aspect of the invention, the label preparing device applies the pre-coating liquid to at least the peripheral parts of the label piece after performing laser cutting. Therefore, the label preparing device applies ink to the peripheral parts of the label piece in a state in which the pre-coated layer is formed. Accordingly, it is possible for the label preparing device to appropriately color the peripheral parts of the label piece.
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
Hereinafter, a label preparing device according to one embodiment of the invention will be described with reference to the accompanying drawings. The label preparing device according to the embodiment prepares a printed label by applying ink to a media which is fed in a roll-to-roll manner.
First, the media will be described.
As illustrated in
Subsequently, the label preparing device 1 will be described.
The label preparing device 1 includes a delivering section 2, a winding section 3, and a media processing unit 4. In addition, a buffer section 5 is provided between the winding section 3 and the media processing unit 4. The media 100, which is fed from the media processing unit 4, is temporarily stored in the buffer section 5.
The delivering section 2 includes a delivering shaft 6 and a delivery-side intermediate roller 7. The delivering shaft 6 delivers the set label roller 100R, and rotatably supports the label roller 100R. The media 100, which is fed from the label roller 100R, is transmitted to the media processing unit 4 through the delivery-side intermediate roller 7.
The winding section 3 includes a winding shaft 8 and a winding-side intermediate roller 9. The winding shaft 8 winds the media 100, which is fed from the media processing unit 4 through the winding-side intermediate roller 9, in a roller shape. The winding shaft 8 is rotatably driven by a winding shaft driving section which is not shown in the drawing. More specifically, the drive of the winding shaft 8 is controlled based on the result of detection of the slack position of the media 100 in the buffer section 5.
The media processing unit 4 includes a media feed section 11, a platen 12, a laser cutting section 13, a print section 14, and a leaving lift section 15.
The media feed section 11 includes an upstream roller group 16 and a downstream roller group 17. The upstream roller group 16 and the downstream roller group 17 are respectively provided upstream and downstream while interposing the platen 12 therebetween.
The upstream roller group 16 feeds the media 100, which is fed from the delivering section 2, to the platen 12. The upstream roller group 16 sequentially includes a first upstream-side roller 21, a second upstream-side roller 22, and a pair of upstream rollers 23 from the upstream side. The first upstream-side roller 21 and the second upstream-side roller 22 perform slave rotation according to the feeding of the media 100. The rotation of the pair of upstream rollers 23 is driven by an upstream feed driving section which is not shown in the drawing. The meandering or the like of the media 100 is corrected by an approximately “V”-shaped feed path which is formed by the first upstream-side roller 21, the second upstream-side roller 22, and the pair of upstream rollers 23.
The downstream roller group 17 feeds the media 100, which is transmitted from the platen 12, to the winding section 3. The downstream roller group 17 sequentially includes a first downstream-side roller 31, a second downstream-side roller 32, a downstream third roller 33, and a pair of downstream rollers 34 from the upstream side. The first downstream-side roller 31, the second downstream-side roller 32, and the downstream third roller 33 performs slave rotation according to the feeding of the media 100. The rotation of the pair of downstream rollers 34 is driven by a downstream feed driving section which is not shown in the drawing. The meandering or the like of the media 100 is corrected by an approximately “U”-shaped feed path which is formed by the first downstream-side roller 31, the second downstream-side roller 32, the downstream third roller 33, and the pair of downstream rollers 34.
In the media feed section 11 which is configured as described above, when laser cutting is completely performed on the media 100 on the platen 12 and ink A (refer to
The upper surface of the platen 12 is set to an area in which laser cutting is performed on the media 100 and ink A is applied to the media 100. A plurality of suction holes (not shown in the drawing), which are connected to a suction fan 35, are provided on the upper surface of the platen 12. The suction fan 35 is driven when the operation of the media feed section 11 stops. Therefore, the media 100 is adsorbed onto the upper surface of the platen 12, and thus the media 100 becomes to be in an immobile state. In contrast, the drive of the suction fan 35 stops when the media feed section 11 is operated. Therefore, the adsorption of the media 100 of the upper surface of the platen 12 is released, and thus the feeding of the media 100 is permitted.
The laser cutting section 13 forms a cutting line 103, which is the outline of a label piece 104, on the media 100 (refer to
As illustrated in
The oscillator 41 oscillates laser beams. It is possible to use carbon dioxide gas laser, YAG laser, or the like as the oscillator 41. Laser beams, which are emitted from the oscillator 41, are incident to the second lens 43 after the diameters of the beams are enlarged by the first lens 42. The second lens 43 emits laser beams such that the laser beams are converged at one point on the media 100. The laser beams, which are emitted from the second lens 43, are reflected in the first mirror 44 and the second mirror 45, and thus the media 100 is irradiated with the laser beams.
The first lens moving section 46 causes the first lens 42 to move along the optical axes of the laser beams. Therefore, the distance between the first lens 42 and the second lens 43 changes, and thus it is possible to adjust the focal distance of the laser beams. Meanwhile, the first lens moving section 46 includes, for example, a stepping motor as a driving source.
The first motor 47 rotates the first mirror 44, thereby changing the angle thereof. In addition, the second motor 48 rotates the second mirror 45, thereby changing the angle thereof. It is possible to use, for example, a stepping motor, as the first motor 47 and the second motor 48. The laser cutting section 13 causes laser beams to scan the media 100 two-dimensionally by changing the angles of the first mirror 44 and the second mirror 45. Meanwhile, laser beams may be caused to scan using an X-Y plotter method instead of the galvano method.
As illustrated in
The print section 14, which is configured as described above, prints an image on the media 100 in such a way that the recording heads 54, which are mounted on the carriage 51, move in the X-axial direction and the Y-axial direction by the X-axial table 52 and the Y-axial table and discharge ink A to the print surface 100a of the media 100 which is adsorbed on the platen 12.
The leaving lift section 15 is provided on the downstream side of the platen 12. The leaving lift section 15 includes a leaving lift roller 25 and a leaving shaft 26. A label leaving 105 (refer to
The control system of the label preparing device 1 will be described with reference to
The controller 60 includes a Central Processing Unit (CPU), a Read Only Memory (ROM), and a Random Access Memory (RAM) which are not shown in the drawing. The CPU of the controller 60 loads a program from the ROM and executes the program using the RAM, and controls the entire operation of the label preparing device 1.
The controller 60 includes a data acquisition unit 61, a main control unit 62, a feed control unit 63, a cut control unit 64, and a print control unit 65. At least a part of the functional units is realized in such a way that a prescribed program is executed by the controller 60.
The data acquisition unit 61 acquires cut data and print data. The cut data is used to form a star-shaped cutting line 103 (refer to
The main control unit 62 controls the feed control unit 63, the cut control unit 64, and the print control unit 65 such that a printed label 106 is prepared to a number which is specified by the user.
After laser cutting and applying of ink A are performed, the feed control unit 63 controls the media feed section 11 such that the media 100 is transmitted as much as the unit area. The cut control unit 64 controls the laser cutting section 13 based on the cut data. The print control unit 65 controls the print section 14 based on the print data.
An order in which the label preparing device 1 prepares the printed label 106 on the media 100 will be described in detail with reference to
As illustrated in
Subsequently, in the label preparing device 1, the print section 14 applies ink A to the media 100 which is adsorbed on the platen 12, as illustrated in
Thereafter, in the label preparing device 1, the media feed section 11 transmits the media 100 as much as the unit area. Therefore, as illustrated in
A case, in which the label preparing device 1 performs laser cutting (refer to
Description will be made more specifically with reference to photographs illustrated in
The photographs illustrated in
Meanwhile, diagrams in which the photographs illustrated in
As understood with reference to
In contrast, the label preparing device 1 according to the embodiment applies ink A to the peripheral parts of the label piece 104, that is, peripheral inclined surfaces 101a which are formed through laser irradiation after performing laser cutting on the media 100, as described above. Therefore, the peripheral inclined surfaces 101a are colored by ink A. Therefore, it is possible for the label preparing device 1 to prepare the label piece 104 which has the colored peripheral parts.
The label preparing device 1 according to the embodiment performs laser cutting on the media 100 in a state being adsorbed on the platen 12, that is, the media 100 in an immobile state, and then applies ink A to the media 100 in a state being adsorbed on the platen 12, that is, in a state in which the immobile state is maintained. Therefore, it is possible for the label preparing device 1 to appropriately apply ink A to the peripheral parts of the label piece 104 without detecting a position where the label piece 104 is formed.
In the label preparing device 1 according to the embodiment, the laser cutting section 13 performs half cutting on the media 100. Therefore, laser beams are prevented from passing through the media 100 and being irradiated to the upper surface of the platen 12. Therefore, it is possible for the label preparing device 1 to prevent the upper surface of the platen 12 from being damaged when the media 100 is irradiated with laser beams.
Meanwhile, it is apparent that the invention is not limited to the above-described embodiment and various configurations are possible without departing from the gist of the invention. For example, it is possible to change the embodiment to the following forms.
The label preparing device 1 may apply ink A to the media 100 based on the print data which is processed such that the print density of the peripheral parts of the label piece 104 increases.
In a modification example, as illustrated in
An order that the print data processing unit 66 processes the print data will be described with reference to
As described above, the label preparing device 1 according to the modification example applies ink A to the media 100 based on the print data which is processed such that the print density of the peripheral part of the label piece 104 increases. Therefore, even when the peripheral inclined surfaces 101a, which are formed through laser irradiation, has bad placement of ink A compared to the print surface 100a of the media 100, it is possible for the label preparing device 1 to color the peripheral inclined surfaces 101a, that is, the peripheral parts of the label piece 104 with appropriate print density. For example, if the label preparing device 1 applies ink A without processing the print data when original print data is used to apply ink A to the label piece 104 with uniform print density and when the peripheral inclined surfaces 101a has bad placement of ink A compared to the print surface 100a of the media 100, the print density of the peripheral part of the label piece 104 becomes low compared to the print density of an area other than the peripheral part. In contrast, even in such a case, it is possible for the label preparing device 1 according to the modification example to color the peripheral part of the label piece 104 with the same print density as in the area other than the peripheral part.
Meanwhile, it is not necessary for the label preparing device 1 to use a regular value as the overlap value, and the label preparing device 1 may acquire the overlap value from a database that combines a condition, such as the material of the label connection body 101 or the intensity of laser beams, which affects the width of the peripheral inclined surface 101a, with the overlap value (for example, a database in which the overlap value is set to 3 pixels in a case of a resin film and the overlap value is set to 1 pixel in a case of paper with regard to the material of the label connection body 101).
Similarly, it is not necessary for the label preparing device 1 to use a regular value as the density value, and the label preparing device 1 may acquire the density value from a database that combines a condition, such as the material of the label connection body 101 or the intensity of laser beams, which affects the details of the placement of ink A in the peripheral inclined surface 101a, with the density value (for example, a database in which the density value is set to an increase of 10% in a case of a resin film and the density value is set to an increase of 20% in a case of paper with regard to the material of the label connection body 101).
In addition, ink is not limited to ink A which includes CMYK colors. For example, when the label preparing device 1 applies another ink A, such as clear ink, which does not include color materials, or pre-coating liquid B, which will be described later, the label preparing device 1 may process the print data such that the print density of the peripheral part of the label piece 104 increases, in other words, such that the amount of applied ink A or pre-coating liquid B increases.
The label preparing device 1 may apply the pre-coating liquid B (refer to
In the modification example, the print section 14 includes pre-coating heads 55 (refer to
As illustrated in
An order that the label preparing device 1 according to the modification example prepares the printed label 106 on the media 100 will be described based on the difference from the above-described embodiment with reference to
When the label preparing device 1 according to the modification example starts to prepare the printed label 106, the laser cutting section 13 forms the label piece 104 as illustrated in
Unlike the modification example, a case in which the label preparing device 1 performs laser cutting (refer to
In contrast, the label preparing device 1 according to the modification example applies the pre-coating liquid B to at least the peripheral parts of the label piece 104 after performing laser cutting, as described above. Therefore, the label preparing device 1 applies ink A to the peripheral parts of the label piece 104 in a state in which the pre-coated layer 111 is formed. Accordingly, it is possible for the label preparing device 1 to appropriately color the peripheral parts of the label piece 104.
A case, in which the printed label 106 is prepared on the media 100 in which the pre-coated layer 111 is formed on the print surface 100a in advance (refer to
It is possible for the laser cutting section 13 to form an arbitrary shaped label piece 104 while not being limited to the star-shaped label piece 104. Similarly, it is possible for the print section 14 to apply ink A to an arbitrary shape while not being limited to the star shape. In addition, it is not necessary for the shape of the label piece 104, which is formed by the laser cutting section 13, to be the same as the shape of ink A (the shape of an image) which is applied by the print section 14. That is, it is not necessary for the print section 14 to apply ink A to the entire label piece 104, and the print section 14 may apply ink A to at least the peripheral parts of the label piece 104. In addition, the print section 14 may apply ink A such that ink A is bulged from the cutting line.
