  The first detection means 15 includes an imaging means such as a camera, an optical sensor, and the like, and detects and detects the adhesive sheet AS before the unrolled RS adhesive sheet AS reaches the first printing means 16. The result is provided so as to be output to control means such as a personal computer or a sequencer (not shown).

  The first printing unit 16 is provided downstream of the first detection unit 15 in the feed-out direction of the original fabric RS, and is opposed to the first printing head 28 capable of printing on the adhesive sheet AS, and the first printing head 28. The roller-type first platen 29 that guides the original fabric RS to the first print head 28, the first print head 28 is supported by the first slider 31, and the first platen 29 is supported by the first print head 28. 2 is a drive device that is supported by a slider 32 and moves the first print head 28 and the first platen 29 away from and close to the original fabric RS, and includes a first linear motion motor 33 as a first moving means. The first printing unit 16 can perform printing by the first printing head 28 on the adhesive sheet AS of the original fabric RS that passes between the first printing head 28 and the first platen 29. When the adhesive sheet AS is composed of thermal paper, the first print head 28 can perform printing directly by applying heat to the adhesive sheet AS, and when the adhesive sheet AS is not composed of thermal paper, An ink ribbon is interposed between the first print head 28 and the adhesive sheet AS, and heat is applied to the ink ribbon so that printing can be performed indirectly.

  The second detection means 18 is provided downstream of the first printing means 16 in the feed direction of the original fabric RS. The second detection means 18 includes imaging means such as a camera equivalent to the first detection means 15, an optical sensor, and the like, and is fed out. Before the anti-RS adhesive sheet AS reaches the second printing means 19, the first printing means 16 detects whether or not predetermined printing is performed on the adhesive sheet AS, and the detection result is not shown in a personal computer or the like It is provided so that it can be output to control means such as a sequencer.

The second printing unit 19 has a structure substantially the same as that of the first printing unit 16 except that the second printing unit 19 is provided downstream of the second detection unit 18 in the feed direction of the original fabric RS. Therefore, the second printing unit 19 rewrites the configuration of “first...” In the above description of the first printing unit 16 to “second...” And adds “′” to the end of the code. The description can be omitted.
A third detection unit 50 including an image pickup unit such as a camera equivalent to the first and second detection units 15 and 18, an optical sensor, and the like is disposed downstream of the second printing unit 19 in the feed direction of the original fabric RS. It is provided so as to detect whether or not predetermined printing is performed on the adhesive sheet AS and output the detection result to a control means such as a personal computer or a sequencer (not shown).

  Next, a method for applying the adhesive sheet AS according to the embodiment will be described.

First, as shown in FIG. 1, the original fabric RS is set in the feeding means 14. When an automatic operation command is input to a control unit (not shown), the first printing unit 16 drives the first linear motor 33 so that the first printing head 28 can perform printing. 28 and the first platen 29 are brought close to the original fabric RS, and the second printing means 19 is moved to the second linear motor 33 ′.
, And the second print head 28 'and the second platen 29' are arranged at a position away from the original fabric RS by a predetermined distance. As described above, the print heads 28 and 28 ′ and the platens 29 and 29 ′ that do not perform printing are kept away from the original fabric RS, so that deterioration, wear, damage, and the like thereof can be avoided and the life can be extended. Note that the service life is the number of prints and the print time of the first and second print heads 28, 28 'and the first and second platens 29, 29' guaranteed by the manufacturer, or the print becomes thin visually. This is the time when the first and second platens 29 and 29 'are determined to be worn.

  Then, when the feeding means 14 drives the rotation motor DM and rotates the driving roller 24 to feed the support shaft original fabric RS, the adhesive sheet AS of the original fabric RS is detected by the first detection means 15, and then a predetermined amount At the timing, the first printing unit 16 drives the first print head 28 to print on the base sheet BS of the adhesive sheet AS.

Even after printing on the adhesive sheet AS, the feeding means 14 drives the rotation motor DM to feed out the original fabric RS. Then, a detection unit (not shown) detects that the adhesive sheet AS first printed by the first printing unit 16 reaches the tip of the release plate 22 and is peeled from the release sheet RL by a predetermined length by the release plate 22. Then, the feeding means 14 stops the rotation motor DM and enters a standby state. When the adhesive sheet AS that has not been printed by the first printing unit 16 for some reason is detected by the second detection unit 18, the second printing unit 19 detects the second linear motion motor 33 ′.
, The second print head 28 'and the second platen 29' are brought close to the original fabric RS so that printing can be performed by the second print head 28 ', the second print head 28' is driven, The printing content that should have been printed by one printing head 28 is printed on the base material sheet BS of the adhesive sheet AS that has not been printed. After that, when the second detection means 18 detects that the first printing means 16 is printing on the adhesive sheet AS, the second printing means 19 stops printing with the second print head 28 ', The second linear motion motor 33 ′ is driven to move the second print head 28 ′ and the second platen 29 ′ away from the original fabric RS. As described above, since the second print head 28 'and the second platen 29' may have to approach the original fabric RS immediately, the second linear motion motor 33 'removes them in the standby state in the standby state. The distance away from the center is not particularly limited, but may be about 2 or 3 mm, for example.

  Next, when the conveying means CV conveys the adherend WK in the left direction, the adherend WK is detected by a sensor (not shown), and the feeding means 14 drives the rotation motor DM at a predetermined timing, and the adherend WK. The raw fabric RS is fed out so that the adhesive sheet AS is fed out in accordance with the moving speed of the sheet. By feeding out the raw fabric RS, the adhesive sheet AS is pressed and stuck to the upper surface of the adherend WK by the pressing roller 12 while being peeled off from the release sheet RL.

When the adhesive sheet AS is applied to the adherend WK that is successively conveyed by the conveying means CV in the same manner as described above, for example, the first print head 28 and the first platen 29 are deteriorated, worn, When damage occurs, when the first print head 28 or the first platen 29 is maintained, when the first print head 28 or the first platen 29 is removed, when the ink ribbon is low, the ink ribbon disappears or is cut In some cases, the first printing unit 16 may not print on the adhesive sheet AS for some reason. Even in such a case, in the same manner as described above, the second detection unit 18 detects the adhesive sheet AS that has not been printed by the first printing unit 16, and the second printing unit 19 detects the second print head 28 '. Driven, the printing contents that should have been printed by the first print head 28 are printed on the base sheet BS of the adhesive sheet AS that has not been printed. As described above, when the first printing head 28 or the first platen 29 is replaced or maintained while the second printing unit 19 is printing, the first printing unit 16 drives the first linear motion motor 33. And since the 1st printing head 28 and the 1st platen 29 can be separated from original fabric RS, the operation | work can be performed easily. In addition, although the distance which keeps them away for replacement | exchange or a maintenance is not necessarily limited, For example, about 5-100 mm may be sufficient.
After that, when the first printing means 16 comes to operate normally by repair, replacement, ink ribbon replacement, etc., printing on the adhesive sheet AS by the first printing means 16 is resumed, and the first printing means 16 is detected by the second detection means 18, the second printing means 19 stops printing by the second print head 28 'and drives the second linear motor 33' to drive the second print head 28. 'And the second platen 29' are moved away from the original fabric RS.

  Here, when it is detected for some reason that the first printing unit 16 or the second printing unit 19 is not printing on the adhesive sheet AS1 shown in FIG. 2, the third detection is performed in the same manner as described above. The means 50 detects the adhesive sheet AS1 that has not been printed by the first and second printing means 16 and 19, and the removing means drives the linear motion motor 22B to move the tip plate 22C as shown in FIG. Pull into the release plate body 22A. As a result, the adhesive sheet AS <b> 1 that has not been printed is wound around the winding shaft 26 without being peeled off by the peeling plate 22. When the third detection means 50 detects that printing is performed on the follow-up adhesive sheet AS, the removal means drives the linear motion motor 22B and removes the tip plate 22C from the release plate main body 22A. The adhesive sheet AS to be pulled out and followed is peeled off by the peeling plate 22 and attached to the adherend WK. As a result, the adhesive sheet AS that has not been printed is not affixed to the adherend WK.

  Therefore, according to such an embodiment, even if printing cannot be performed by the first printing unit 16, this can be detected and printing can be performed by the second printing unit 19. Thereby, the printing leak with respect to the adhesive sheet AS of the raw fabric RS extended | drawn out can be suppressed as much as possible. In addition, it is possible to suppress the adhesive sheet AS that has not been printed from being attached to the adherend WK.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.

Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

For example, the printing apparatus 11 can be used by being incorporated in an apparatus other than the sheet sticking apparatus 10, or can be used alone without cooperating with other apparatuses, or can be bonded after printing without peeling off the adhesive sheet AS. The sheet AS may be wound in a state of being temporarily attached to the release sheet RL.
Further, when the first detection unit 15 does not detect the adhesive sheet AS for a predetermined time or longer, the first printing unit drives the first linear motion motor 33, and the first print head 28 and the first platen 29 are moved to the original fabric. Keep away from RS. Thereafter, when the first detection means 15 detects the adhesive sheet AS, the first printing means 16 drives the first linear motion motor 33 to bring the first print head 28 and the first platen 29 close to the original fabric RS, and Printing may be performed on the adhesive sheet AS by one print head 28.

Further, the print heads 28, 28 'and the platens 29, 29' that are not used may not be separated from the original fabric RS, or the platens 29, 29 'may not be separated from the original fabric RS. May be substituted.
In the above-described embodiment, the printing heads 28 and 28 ′ and the platens 29 and 29 ′ are spaced apart from the original fabric RS by a single linear motor 33 and 33 ′ for each printing unit 16 and 19. However, it is also possible to adopt a configuration in which four drive devices that individually move the print heads 28 and 28 'and the platens 29 and 29' are individually moved away from and close to the original fabric RS. .

It may be moved so as to be spaced apart from the original fabric RS.
Further, the removing means may be configured such that the entire peeling plate 22 moves forward and backward in the feed direction of the original fabric RS, or the tip plate 22C may be bent with respect to the peeling plate main body 22A. That is, even when a roller or the like is used instead of the release plate 22, a configuration in which the release plate 22, the roller, or the like is moved so as not to apply tension to the release sheet RL when the release sheet RL is folded back is sufficient.
Further, as shown by a two-dot chain line in FIG. 1, the removing means includes a linear motion motor 61 as a driving device and a holding plate 63 supported by the output shaft 62 and capable of adsorbing and holding the adhesive sheet AS. May be. When the third detection unit 50 determines that printing has not been performed on the adhesive sheet AS, the removing unit drives the linear motion motor 61 to remove the adhesive sheet AS that has not been printed by the holding plate 63. It is held by suction and removed from the release sheet RL. Note that the second and subsequent adhesive sheets AS removed by the holding plate 63 are held by the adhesive layer AD of the adhesive sheet AS previously removed. Further, the holding plate 63 may be configured by a driving device such as a chuck cylinder capable of gripping the adhesive sheet AS in addition to the suction holding.

In addition, another detection unit having the same configuration as the first and second detection units 15 and 18 and another printing unit having the same configuration as the first and second printing units 16 and 19 are added to the original fabric. They may be provided side by side in the RS feeding direction.
Further, the print heads 28 and 28 'may be constituted by different ones such as an ink jet printer, a dot impact printer, a letterpress or intaglio printing machine, and are different between the first print head 28 and the second print head 28'. It is good also as a structure which uses the kind of printing means.
Each platen 29, 29 'can be of a plate type or other type in addition to the roller type.
In addition, the type and material of the adherend WK and the adhesive sheet AS in the present invention are not particularly limited. For example, the adhesive sheet AS has an intermediate layer between the base sheet BS and the adhesive layer AD. Or a sheet having three or more layers such as a cover layer on the upper surface of the base sheet BS, or a so-called double-sided adhesive sheet capable of peeling the base sheet BS from the adhesive layer AD. In addition, such a double-sided adhesive sheet may have a single layer or a multilayer intermediate layer, or may be a single layer or a multilayer without an intermediate layer. Further, the adherend may be an appropriate article (for example, food or a resin container), and the adhesive sheet AS may be a label, the adherend is a semiconductor wafer, and the adhesive sheet AS is a protective sheet, A dicing tape, a die attach film, etc. may be sufficient.
