[0009] One embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the X, Y, and Z axes are orthogonal to each other. The X and Y axes are axes within a predetermined plane, and the Z axis is an axis perpendicular to the predetermined plane. Furthermore, in this embodiment, using the view from the front direction in Figure 1(A), which is parallel to the Y axis, as the reference, when directions are indicated without specifying a figure, "up" is the direction of the Z-axis arrow and "down" is the opposite direction, "left" is the direction of the X-axis arrow and "right" is the opposite direction, and "front" is the front direction in Figure 1(A), which is parallel to the Y axis and "back" is the opposite direction.

[0010] An identification mark forming apparatus EA for implementing the identification mark forming method of the present invention includes: a mark forming means 10 that performs a mark forming step of applying a marking agent MA to an object WK and forming a predetermined mark SM (see Figures 1(B) and (E)) molded by the marking agent MA on the object WK; a flow promoting means 20 that performs a flow promoting step to promote the flow of the marking agent MA applied to the object WK; a transition detection means 30 that performs a transition detection step to detect that the predetermined mark SM has transitioned to an individually recognizable identification mark DM (see Figures 1(F) and (G)) due to the morphologically deformed marking agent MA; and a predetermined fixing process applied to the marking agent MA applied to the object WK. The device includes a fixing means 40 that performs a fixing process in which ultraviolet irradiation is applied to forcibly fix the marking agent MA to the object WK to be applied, a lamination means 50 that performs a lamination process in which an adhesive sheet AS as a coating material is laminated onto a base material BM to form the object WK to be applied, an energy application means 60 that performs an energy application process in which heat HA as a predetermined energy is applied to the adhesive sheet AS laminated onto the base material BM, an imaging means 70 that performs an imaging process in which an identification mark DM is captured to form an image and the image is transmitted to another device TA that performs a predetermined processing on the object WK to be applied, and a moving means 80 that performs a moving process in which the object WK to be applied is moved, all of which are located in the vicinity of the device. Furthermore, the marking agent MA is a UV-curing liquid ink that flows and changes shape after being applied to the target object WK. Furthermore, the marking agent MA of this embodiment is forcibly fixed to the target object WK by being subjected to ultraviolet irradiation as a predetermined fixing treatment. Furthermore, the adhesive sheet AS undergoes hardening as a change specific to that heat HA when it is applied as a predetermined energy.

[0011] The mark-forming means 10 includes linear motors 11 as two drive devices that can move each slider 11A in the front-rear direction, linear motors 12 supported by each slider 11A and that can move slider 12A in the left-right direction, an inkjet nozzle 13 supported by slider 12A and that sprays marking agent MA into fine particles onto the object WK to be marked, forming a predetermined mark SM on the object WK that is molded by the collective shape of the marking agent MA, and an ink tank 14 as a storage device that stores the marking agent MA internally and sends the marking agent MA to the inkjet nozzle 13 via a hose 14A. In this embodiment, the mark-forming means 10 is configured to form a predetermined mark SM consisting of the letters "ABC" on the surface of the object WK to be marked, as shown in Figure 1(B).

[0012] The flow promotion means 20 includes a vibrator 21, which is a flow promotion device that applies vibration to the object WK to be treated.

[0013] The transition detection means 30 includes a CCD camera 31 as an imaging device, an image matching device 32 as a matching device, and a RAM 33 as a storage device. The CCD camera 31 forms an image by magnifying a predetermined mark SM applied to the object WK to a predetermined magnification and capturing the image. The image matching device 32 compares the image captured by the CCD camera 31 with the images stored in the RAM 33. If no matching image is found (including cases where there are no images stored in the RAM 33), it determines that the predetermined mark SM that was captured by the CCD camera 31 has transitioned to an identification mark DM. Conversely, if a matching image is found, it determines that the predetermined mark SM that was captured by the CCD camera 31 has not transitioned to an identification mark DM. The RAM 33 stores the images that the image matching device 32 has determined to have transitioned to an identification mark DM.

[0014] The fixing means 40 includes an ultraviolet light emitter 41, which is a fixing device capable of emitting ultraviolet UV light.

[0015] The lamination means 50 includes a base plate 51 that directly or indirectly supports the components constituting the lamination means 50, a support roller 52 that supports a raw roll RS on which an adhesive sheet AS is temporarily attached to a strip-shaped release sheet RL, a guide roller 53 that guides the raw roll RS, a release plate 54 as a release means that folds the release sheet RL at the release edge 54A and peels the adhesive sheet AS from the release sheet RL, a pressing roller 55 as a pressing means that presses the adhesive sheet AS onto the object to be laminated WK and laminates it, a drive roller 56 supported on the output shaft (not shown) of a rotary motor 56A as a drive device and sandwiches the release sheet RL between itself and a pinch roller 56B, and a recovery roller 57 supported on the output shaft of a drive device (not shown) and constantly applies a predetermined tension to the release sheet RL between itself and the pinch roller 56B while the identification mark forming device EA is in automatic operation and recovers the release sheet RL.

[0016] The energy supply means 60 includes a coil heater 61, which is an energy supply device capable of supplying heat HA.

[0017] The imaging means 70 is equipped with a CCD camera 71 as an imaging device, and forms an image by magnifying the identification mark DM applied to the object WK to a predetermined magnification and imaging it, and transmits the image to another device TA.

[0018] The moving means 80 includes a linear motor 81 as a drive device and a support table 82 which is supported by a slider 81A of the linear motor 81 via a flow promoting means 20 and has a support surface 82A that can be held by suction using a pressure reducing means (holding means) not shown, such as a pressure reducing pump or a vacuum ejector.

[0019] The operation of the identification mark forming device EA described above will now be explained. First, with respect to the identification mark forming device EA in which each member is arranged at the initial position indicated by the solid line in FIG. 1(A), after the user of the identification mark forming device EA (hereinafter simply referred to as the "user") sets the original fabric RS as shown in the figure, a signal for starting automatic operation is input via an operation means (not shown) such as an operation panel or a personal computer. Then, the laminating means 50 drives the rotation motor 56A to feed out the original fabric RS. As shown in FIG. 1(A), when the leading end portion in the feeding direction of the first adhesive sheet AS is peeled off from the peeling sheet RL by a predetermined length at the folding portion of the peeling sheet RL folded by the peeling edge 54A of the peeling plate 54, the driving of the rotation motor 56A is stopped. Next, when the user or a conveying means (not shown) such as an articulated robot or a belt conveyor places the base material BM at a predetermined position on the support table 82 as shown in FIG. 1(A), the moving means 80 drives a decompression means (not shown), starts adsorption and holding on the support surface 82A, and then drives the linear motor 81 to move the support table 82 to the left.

[0020] After that, when the base material BM reaches a predetermined position with respect to the laminating means 50, the laminating means 50 drives the rotation motor 56A to feed out the original fabric RS in accordance with the moving speed of the base material BM. As a result, the adhesive sheet AS is peeled off from the peeling sheet RL at the folding portion of the peeling sheet RL, and as shown by the two-dot chain line in FIG. 1(A), it is pressed by the pressing roller 55 and laminated on the base material BM, and the application object WK is formed. Next, after the entire first adhesive sheet AS is laminated on the application object WK and the application object WK is formed, when the leading end portion in the feeding direction of the next adhesive sheet AS following the first adhesive sheet AS is peeled off from the peeling sheet RL by a predetermined length at the folding portion of the peeling sheet RL, the laminating means 50 stops the driving of the rotation motor 56A.

[0021] Then, when the object WK to be applied reaches the energy application position EP of the energy application means 60 indicated by the two-dot chain line in FIG. 1(A), the moving means 80 stops driving the linear motor 81. Next, the energy application means 60 drives the coil heater 61, applies heat HA to the adhesive sheet AS, and cures the adhesive sheet AS. After that, when the adhesive sheet AS is cured, the energy application means 60 stops driving the coil heater 61, and the moving means 80 drives the linear motor 81 to move the support table 82 to the left.

[0022] Next, when the object WK to be marked reaches the marking position MP of the marking means 10 indicated by the two-dot chain line in FIG. 1(A), the moving means 80 stops driving the linear motor 81. Then, the marking means 10 drives the linear motors 11, 12 and the inkjet nozzle 13, sprays the granular marking agent MA onto the object WK to be marked, and forms a predetermined mark SM on the surface of the object WK to be marked as shown in FIGS. 1(B) and (E). Next, when the predetermined mark SM is formed, after the marking means 10 stops driving the inkjet nozzle 13, it drives the linear motors 11, 12 to return the inkjet nozzle 13 to the initial position. When the marking means 10 stops driving the inkjet nozzle 13, the flow promotion means 20 drives the vibrator 21 to start applying vibration to the marking agent MA, and the moving means 80 drives the linear motor 81 to move the support table 82 to the left.

[0023] Subsequently, when the object WK to be marked reaches the ultraviolet irradiation position UP of the fixing means 40, indicated by the dashed line in Figure 1(A), the moving means 80 stops driving the linear motor 81. Next, when the flow promotion means 20 stops driving the vibrator 21, the fixing means 40 drives the ultraviolet light emitter 41 and irradiates the marking agent MA with ultraviolet UV to forcibly fix the marking agent MA to the object WK, and stops driving the ultraviolet light emitter 41 when fixing is complete. Then, the transition detection means 30 drives the CCD camera 31 to capture an image of a predetermined mark SM and form an image, and then drives the image matching device 32 and RAM 33 to compare the image captured by the CCD camera 31 with the image stored in RAM 33. If, as a result of this comparison, the image matching device 32 determines that the predetermined mark SM has transitioned to the identification mark DM, the transition detection means 30 drives the RAM 33 and stores the image captured by the CCD camera 31. Next, the fixing means 40 stops driving the ultraviolet light emitter 41, and the moving means 80 drives the linear motor 81 to move the support table 82 to the left.

[0024] Here, the marking agent MA sprayed onto the object WK flows along the surface of the object WK or penetrates into the surface layer of the object WK before it can settle on the object WK. As shown in Figure 1(C), it deforms into various shapes by joining with neighboring marking agents MA, or as shown in Figure 1(D), it deforms to spread out independently. In this way, the marking agents MA deform into different shapes individually, so that a predetermined mark SM is molded by marking agents MA that have deformed into various shapes, as shown in Figures 1(F) and (G), and is transformed into an identification mark DM that can be individually recognized. In this embodiment, the flow of the marking agent MA is promoted by vibrations applied from the vibrator 21, and the deformation of the marking agent MA is more pronounced compared to when there are no vibrations.

[0025] Subsequently, when the object WK to be marked reaches the imaging position RP of the imaging means 70, indicated by the dashed line in Figure 1(A), the moving means 80 stops driving the linear motor 81. Next, the imaging means 70 drives the CCD camera 71 to capture the identification mark DM applied to the object WK to form an image, and transmits the image to another device TA. Then, the moving means 80 stops driving the depressurization means (not shown) and releases the suction holding on the support surface 82A. After the user or a transport means (not shown) transports the object WK to the other device TA, the moving means 80 drives the linear motor 81 to return the support table 82 to its initial position, and the above operation is repeated thereafter. Furthermore, another device TA stores the image transmitted from the imaging means 70 in a storage device (not shown), and later captures the identification mark DM attached to the object to be assigned WK that is transported, forming an image of it. This image is then compared with the image stored in the storage device (not shown), and if a matching image is found, a predetermined process is applied to the object to be assigned WK that was captured by the imaging device (not shown).

[0026] According to the embodiments described above, it is detected that a predetermined mark SM has been transformed into an individually recognizable identification mark DM by the morphologically deformed marking agent MA, so that the identification mark DM can be formed on the object WK to be marked by a new method.

[0027] The means and processes in the present invention are not limited in any way as long as they can perform the operations, functions, or processes described for those means and processes, and are certainly not limited in any way to the components or processes of a single embodiment shown above. For example, the mark-forming means can be anything that can apply a marking agent to an object to be marked and form a predetermined mark molded by the marking agent on the object, and is not limited in any way as long as it is within the scope of the common technical knowledge at the time of filing (the same applies to other means and processes).

[0028] The marking means 10 may employ an articulated robot as a driving device instead of at least one of the linear motors 11 and 12, or a marking agent MA may be applied to at least one of the base material BM and the coating material. For example, characters such as "ABCDEF", "あいう", "壱弐参", numbers including Chinese numerals such as "12345", "一二三四", "百千万", and symbols such as "!#%&", "+", "-", "×", "÷", "、", "。A predetermined mark SM may be formed on the object to be marked WK in any form, such as symbols like "· / 」, patterns like "●■▲", "◎▽◇", etc. For example, a predetermined mark SM consisting of only one notation, such as only "A", only "1", only "#", only "●", etc., may be formed on the object to be marked WK. For example, a predetermined mark SM consisting of a notation formed by combining a plurality of elements from the same form, such as "いろは", "AAA", "56298", "#$%!?", "●▽◇▲", may be formed on the object to be marked WK. For example, a predetermined mark SM consisting of a notation formed by combining one or more elements from different forms, such as "あA1●#", "KをC3●▲!&", "%38語AA▲□+ / ", may be formed on the object to be marked WK. Instead of a collective shape, a predetermined mark may be imitated by one marking agent MA. For the object to be marked WK, a predetermined mark SM consisting of different notations may be formed for each unit. For all objects to be marked WK, a predetermined mark SM consisting of the same notation may be formed. The marking agent MA may be applied to the object to be marked WK in any form such as a cube shape, a cylindrical shape, a prismatic shape, a spherical shape, an ellipsoidal shape, etc. As a marking device, for example, in addition to a letterpress printer, an intaglio printer, a lithographic printer, a silk printer or a screen printer that applies the marking agent MA to the object to be marked WK using a plate, an inkjet printer, a dot impact printer, a thermal printer, a thermal transfer printer, a laser printer, etc. may also be adopted. As long as a predetermined mark SM imitated by the marking agent MA can be formed on the object to be marked WK considering the characteristics, qualities, properties, materials, compositions and configurations, etc. of the marking agent MA, any marking device may be adopted. While moving the object to be marked WK or in a state where the movement of the object to be marked WK is suppressed, the marking device may be moved to apply the marking agent MA to the object to be marked WK. While moving the object to be marked WK or in a state where the movement of the object to be marked WK is suppressed, the movement of the marking device may be suppressed to apply the marking agent MA to the object to be marked WK.

[0029] The flow promotion means 20 may employ an eccentric motor, piston vibrator, or electrodynamic motor as a flow promotion device, or it may employ a flow promotion device that applies vibration in any direction, such as vertical, horizontal, front-back, circumferential, or other directions, or vibration in a combination of these directions, and it is not limited to a flow promotion device that applies vibration to the target object WK or marking agent MA via the support table 82, but any flow promotion device may be employed, such as a flow promotion device that applies vibration to the target object WK or marking agent MA via a linear motor 81, or a flow promotion device that applies vibration directly or indirectly to the target object WK or marking agent MA without going through the components of the moving means 80, and for example, a flow promotion device that promotes the flow of the marking agent MA by blowing a gas such as air or gas onto the target object WK or marking agent MA may be employed, or a flow promotion device that promotes the flow of the marking agent MA by tilting the target object WK may be employed, or a plate A flow-promoting device that promotes the flow of the marking agent MA by bringing contact members such as shaped members, rod-shaped members, and brush-shaped members into contact may be used. Alternatively, a flow-promoting device that promotes the flow of the marking agent MA by applying energy such as electromagnetic waves such as ultraviolet rays, infrared rays, visible light, sound waves, X-rays, or gamma rays, heating such as hot water or hot air, or cooling such as cold water or cold air to the marking agent MA applied to the object WK may be used. Any flow-promoting device that can promote the flow of the marking agent MA, taking into consideration the characteristics, properties, materials, composition, and structure of the marking agent MA, may be used. The flow of the marking agent MA may be promoted by moving the flow-promoting device while moving the object WK, or while suppressing the movement of the flow-promoting device while moving the object WK, or while suppressing the movement of the object WK, or the flow of the marking agent MA may be promoted by suppressing the movement of the flow-promoting device. The identification mark forming apparatus EA of the present invention may or may not be equipped with such a device.

[0030] The transition detection means 30 may employ any imaging device such as an infrared camera, ultraviolet camera, ultrasonic camera, X-ray camera, optical sensor, ultrasonic sensor, area sensor, line sensor, image sensor, digital camera, microscope camera, film camera, etc., as an imaging device, any storage device such as flash memory, CD-ROM, DVD-ROM, etc., as a comparison device, any image comparison tool, AI tool, etc., may be employed, and the predetermined mark SM may be enlarged to 2x, 1000x, etc., reduced to 1 / 2x, 1 / 15x, etc., or at 1x size when imaging, or a part or all of the predetermined mark SM applied to the object WK to be applied to may be imaged, or the predetermined mark SM may be imaged by moving the imaging device while moving the object WK to be applied to, or while suppressing the movement of the object WK to be applied to, while suppressing the movement of the imaging device and imaging the predetermined mark SM. The transition detection means 30 may be an integrated system comprising at least two of the imaging device, matching device, and storage device, or one of the functions of the imaging device, matching device, and storage device may be equipped with at least one of the other two functions, or it may also function as an imaging means 70 by being configured to transmit the same image stored in the storage device to another device TA, and if the matching device determines that a predetermined mark SM has not transitioned to an identification mark DM as a result of the matching, it may output a drive start signal such as an electrical signal or radio wave signal to a warning means such as a light emitter or sound emitter to inform the user by light or sound, or it may output a drive start signal to an exclusion means such as a reject device or drive device to remove the assigned object WK that was the subject of matching from the identification mark forming device EA Alternatively, the marking agent MA may be removed, or a verification device may be used to verify the marking agent MA before it settles on the object WK to be applied. If the verification determines that the predetermined mark SM has not transitioned to the identification mark DM, the flow promotion means 20 may again drive the vibrator 21 for a predetermined time, or after a predetermined time has elapsed without the flow promotion means 20 driving the vibrator 21, the verification operation of imaging the predetermined mark SM with the imaging device and verifying it with the verification device may be repeated until it is determined that the predetermined mark SM has transitioned to the identification mark DM. Alternatively, if it is determined that the mark has not transitioned to the identification mark DM even after repeating the verification operation a predetermined number of times, a drive start signal may be output to the warning means or the removal means, and the object WK that was the target of verification may be removed from the identification mark forming device EA.

[0031] The fixing means 40 may be an infrared irradiation device or an X-ray irradiation device if the marking agent MA is forcibly fixed by an electromagnetic wave irradiation treatment that irradiates it with electromagnetic waves such as ultraviolet rays, infrared rays, visible light, sound waves, X-rays or gamma rays; an infrared irradiation device or an X-ray irradiation device may be used as the fixing device if the marking agent MA is forcibly fixed by a heating treatment that applies a heating medium such as hot air or hot water; a coil heater or an infrared irradiator may be used as the fixing device if the marking agent MA is forcibly fixed by a cooling treatment that applies a cooling medium such as cold air or cold water; a blower or a Peltier element may be used as the fixing device if the marking agent MA is forcibly fixed by a drying treatment such as blowing air or heating; or an oxygen spraying device or a hardening agent filling device may be used as the fixing device if the marking agent MA is forcibly fixed by an application treatment that applies another substance. Considering the characteristics, properties, materials, composition, and structure, any fixing device that can forcibly fix the marking agent MA to the object WK may be used as the fixing device, and it may be provided in a location other than the position shown in the above embodiment, and it may be provided anywhere as long as it can forcibly fix the marking agent MA to the object WK, and the marking agent MA may be forcibly fixed to the object WK by moving the fixing device while moving the object WK or while the movement of the object WK is suppressed, or the marking agent MA may be forcibly fixed to the object WK by suppressing the movement of the fixing device while moving the object WK or while the movement of the object WK is suppressed, and a predetermined fixing treatment may be performed on the marking agent MA immediately after it has been applied to the object WK, or after a predetermined time has elapsed, and it may or may not be provided in the identification mark forming apparatus EA of the present invention.

[0032] The lamination means 50 may peel off the adhesive sheet AS from the roll RS, where a predetermined area partitioned by the cut is an adhesive sheet AS, and laminate it onto the base material BM, by forming a closed loop-shaped or entire-length cut in the adhesive sheet substrate that is temporarily attached to the strip-shaped release sheet RL, and laminating the adhesive sheet AS onto the base material BM. Alternatively, a strip-shaped adhesive sheet roll in which a strip-shaped adhesive sheet substrate is temporarily attached to the strip-shaped release sheet RL may be used, and while the strip-shaped adhesive sheet roll is being fed out, a closed loop-shaped or entire-length cut in the adhesive sheet substrate may be formed with a cutting blade as a cutting means, and the adhesive sheet AS may peel off from the roll RS, where a predetermined area partitioned by the cut is an adhesive sheet AS, and laminate it onto the base material BM.

When laminating the adhesive sheet AS onto the base material BM, the speed of the fed-out roll RS is... Lamination tension control may be performed to control the tension so that a predetermined tension is applied to the adhesive sheet AS, or so that tension is not applied. Alternatively, the adhesive sheet AS may be peeled off from a raw material RS that has been fan-folded, for example, without being wound, and laminated onto the base material BM. Alternatively, a pressing means may be employed in which the adhesive sheet AS is held by a holding member supported on the output shaft of a linear motor as a drive device and can be held by adsorption by a depressurization means (not shown) such as a depressurization pump or a vacuum ejector, and the adhesive sheet AS held by the holding member is pressed onto the base material BM for lamination. Alternatively, a recovery means may be employed to recover the release sheet RL without winding, for example by fan-folding, shredding, or haphazardly accumulating it. Alternatively, no recovery means may be employed, or an adhesive sheet AS that is not temporarily attached to the release sheet RL may be used. The lamination means 50 may laminate the adhesive sheet AS on only one surface or only the other surface of the base material BM, or on both the one surface and the other surface, or as shown in Figure 1(B), it may laminate the adhesive sheet AS on a part of one surface of the base material BM, or on the entire surface of one surface of the base material BM, or on all or part of all surfaces of the base material BM, or it may laminate the adhesive sheet AS on the base material BM by moving the base plate 51 while moving the base material BM or while the movement of the base material BM is suppressed, or it may laminate the adhesive sheet AS on the base material BM while moving the base plate 51 while moving the base material BM or while the movement of the base material BM is suppressed, or it may laminate the coating material on the base material BM by spraying or applying the coating material, and any method that can form the object WK to be applied by laminating the coating material on the base material BM is acceptable, and it may or may not be provided in the identification mark forming apparatus EA of the present invention.

[0033] The energy-imparting means 60 may apply a predetermined amount of energy to the coating material by moving the energy-imparting device while moving the object WK to be imparted, or while moving the object WK to be imparted, or while suppressing the movement of the energy-imparting device, and applying a predetermined amount of energy to the coating material, or applying a predetermined amount of energy to the entire coating material or a part of the coating material, and the energy-imparting device may apply electromagnetic waves such as ultraviolet rays, infrared rays, visible light, sound waves, X-rays or gamma rays, or a heating medium such as hot water or hot air, or a cooling medium such as cold water or cold air, or any other type of energy. Any device may be used, and any device may be used as long as it can cause the coating agent to undergo an energy-specific change, taking into consideration the characteristics, properties, materials, composition and structure of the coating agent. For example, as shown by the dashed line in Figure 1(A), a coil heater 62 may be used as an energy supply device that is placed inside the support table 82 or on the support surface 82A and can supply heat as a predetermined energy. Both coil heaters 61 and 62 may be used, or either coil heater 61 or coil heater 62 may be used.

It may also image the identification mark DM by moving the imaging device while moving the object WK or while suppressing the movement of the object WK. It may also image the identification mark DM while moving the object WK or while suppressing the movement of the object WK, with the movement of the imaging device suppressed. The identification mark forming apparatus EA of the present invention may or may not be equipped with this. The imaging means 70 may perform imaging multiple times for a single object WK to be assigned, forming multiple images. In this case, one of these images, several of them (but not all), or all of them may be transmitted to another device TA.

[0035] The moving means 80 may be a support table 82 that cannot be held by suction on the support surface 82A, or the support table 82 may be supported by the slider 81A without the flow promoting means 20, or it may or may not be provided in the identification mark forming apparatus EA of the present invention.

[0036] The identification mark forming apparatus EA may or may not be directly or indirectly connected to the flow promotion means 20, fixing means 40, stacking means 50, energy supply means 60, imaging means 70, or moving means 80. Alternatively, the mark forming means 10, flow promotion means 20, migration detection means 30, fixing means 40, stacking means 50, energy supply means 60, imaging means 70, and moving means 80 may be arranged in appropriate positions so that the mark forming process, flow promotion process, migration detection process, fixing process, stacking process, energy supply process, imaging process, and moving process can be performed in an appropriate order.
