  As shown in FIGS. 4 and 5, the pattern portions 43 and 47 included in the first pattern portion group 42 and the second pattern portion group 46 include a plurality of convex portions 43 a and 47 a. The concavo-convex shape of the concavo-convex pattern 40 different from the concavo-convex portion 35 is configured by the convex portions 43a and 47a.

  The convex portions 43a and 47a are arranged side by side along the other direction on the embossing mold surface 30 (in this example, the circumferential direction of the embossing roll 20 perpendicular to the rotation axis L1 of the embossing roll 20). Each of the convex portions 43a and 47a has a triangular shape (strictly an isosceles triangle) in a cross section orthogonal to one direction on the embossing mold surface 30 (in this example, a cross section orthogonal to the rotation axis L1 of the embossing roll 20). Yes. Further, as shown in FIGS. 1, 5 and 6, each of the convex portions 43a and 47a extends along the one direction on the embossed mold surface 30, and is thus formed in a triangular prism shape.

  As shown in FIGS. 5 and 6, in each pattern portion 43, 47, the plurality of convex portions 43 a, 47 a have the same shape, and between the different pattern portions 43, 47, the convex portions 43 a, 47 a have different shapes. have.

  As shown in FIG. 4, the ratio of the height ha to the length wa of the base in the cross-sectional triangle of the convex portion 43 (ha /) between the convex portions 43a included in different pattern portions 43 in the first pattern portion group 42. wa, hereinafter simply referred to as “aspect ratio of the convex portion”) is the same, and the heights ha of the cross-sectional triangles of the convex portion 43 are different from each other. In particular, as shown in FIG. 3, the first pattern portion group 42 has ten pattern portions 43. As a result, the first pattern portion group 42 has ten different heights ha. The convex part 43a which has is included. Moreover, the maximum value of the height ha of the convex portion 43a included in the first pattern portion group 42 is the same as the maximum value of the heights of the convex portions constituting the concave-convex shape of the concave-convex portion 35. . As a specific example, when the processed product 80 to be manufactured is a release paper (pattern paper) for synthetic leather, the maximum height of the convex portion 43a included in the first pattern portion group 42 is, for example, 50 μm. Can do.

  On the other hand, as shown in FIG. 5, the heights ha of the cross-sectional triangles of the convex portions 47a are the same between the convex portions 47a included in the different pattern portions 47 in the second pattern portion group 46, and the convex portions 47a. The ratio of the height ha to the base length wa (the aspect ratio (ha / wa) of the protrusions) in the cross-sectional triangle of FIG. In particular, as shown in FIG. 3, the second pattern portion group 46 includes ten pattern portions 47. As a result, the second pattern portion group 46 includes ten different aspect ratios (ha). A convex portion 47a having / wa) is included. In addition, the maximum value of the ratio of the height ha to the base length wa in the cross-sectional triangle of the convex portion 47 a included in the second pattern portion group 46 is that of the convex portion having a triangular cross-section included in the concave-convex portion 35. It is the same as the maximum aspect ratio. As a specific example, when the manufactured product 80 to be manufactured is a release paper (pattern paper) for synthetic leather, the maximum value of the aspect ratio of the convex portion 47a included in the second pattern portion group 46 is, for example, 1.0. can do.

  The aspect ratio (ha / wa) of the convex portions 43a included in the first pattern portion group 42 is constant as described above. Here, the aspect ratio of the convex portion 43a included in the first pattern portion group 42 is, for example, a half value of the maximum value of the aspect ratio of the convex portion constituting the concave-convex shape of the concave-convex portion 35, or the concave-convex portion. It can be set to an approximately average value of the aspect ratio of the convex portions constituting the concave-convex shape of the portion 35. Further, the height ha of the convex portion 47a included in the second pattern portion group 46 is constant as described above. Here, the height of the convex portion 47a included in the second pattern portion group 46 is, for example, a value that is half the maximum value of the height of the convex portion constituting the concave-convex shape of the concave-convex portion 35, or the concave-convex portion. It can be set to a substantially average value or the like of the height of the convex portion constituting the concave-convex shape of the portion 35.

  The height ha of the convex portion and the aspect ratio (ha / wa) of the convex portion on the embossed mold surface 30 are two parameters that can have a significant influence on the transfer efficiency of the concave and convex shape to the original fabric 70. The uneven pattern 40 has an uneven shape including various heights that can be included in the uneven shape of the uneven portion 35 and various aspect ratios that can be included in the uneven shape of the uneven portion 35. That is, the inspection concavo-convex pattern 90 formed on the original fabric 70 by the concavo-convex pattern 40 has a concavo-convex shape of the concavo-convex pattern 85 formed on the original fabric 70 by the concavo-convex portion 35 and a concavo-convex shape that is very relevant. become. The transfer efficiency when the concavo-convex pattern 40 is transferred as the inspection concavo-convex pattern 90 to the original fabric 70 has a strong correlation with the transfer efficiency when the concavo-convex portion 35 is transferred as the concavo-convex pattern 85 to the original fabric 70. It becomes like this. Therefore, by inspecting the inspection concavo-convex pattern 90 formed on the original fabric 70 by the concavo-convex pattern 40, the concavo-convex shape of the concavo-convex pattern 85 formed on the original fabric 70 by the concavo-convex portion 35 and having a complicated concavo-convex shape can be accurately obtained. It becomes possible to confirm.

  In addition, although the various points of the uneven | corrugated shape formed in the embossing type | mold surface 30 have been demonstrated in detail, the various points regarding the shape mentioned above, for example, cross-sectional shape (triangle shape etc.) of a convex part, the height of a convex part, are mentioned. The aspect ratio or the like of the convex portion does not necessarily require strictness, and it is sufficient to consider it as an approximate one. For example, a deviation from the above description due to a manufacturing error or the like may naturally be ignored.

  Further, as shown in FIG. 3, in the vicinity of the pattern portions 43 and 47 of the embossing mold surface 30, marks 39 a and 39 a that indicate the characteristics of the shapes of the convex portions 43 a and 47 a included in the pattern portions 43 and 47, respectively. 39b is attached. Further, as shown in FIGS. 3 and 2, the embossing mold surface 30 further has a register mark portion 37 for specifying the position of the concave / convex pattern 40. For example, as shown in FIG. 3, the register mark portion 37 can be configured as a cross-shaped protrusion. In the example shown in the drawing, the registration mark portion 37 includes a plurality of pattern portions 43 included in the first pattern portion group 42 and a plurality of pattern portions 47 included in the second pattern portion group 46, and the circumference of the embossing roll 20. Arranged side by side. These marks 39a and 39b and the register mark portion 37 make it easy to specify the positions of the plurality of pattern portions 43 included in the first pattern portion group 42 and the plurality of pattern portions 47 included in the second pattern portion group 46. Become. Accordingly, the position of the inspection concave / convex pattern 90 formed on the original fabric 70 by the concave / convex pattern 40 can be easily specified. Thereby, handling of the uneven pattern 40 and handling of the inspection uneven pattern 90 formed on the original fabric 70 by the uneven pattern 40 can be facilitated.

  Next, the backup roll 13 disposed to face the embossing roll 20 will be described. The backup roll 13 has substantially the same diameter as the embossing roll 20. The backup roll 13 is configured to be synchronized with the embossing roll 20 and to rotate at a circumferential speed substantially the same as the circumferential speed of the embossing roll 20.

  Further, the backup roll 13 is a surface layer that is pressed by the embossing mold surface 30 and can be deformed corresponding to the uneven shape formed on the embossing mold surface 30 and can maintain the deformed state for at least a certain period. have. That is, the backup roll 13 functions as a female type having versatility with respect to the embossing roll 20 having various uneven shapes as the embossing mold surface 30. As such a backup roll 13, for example, a roll-shaped member called a paper roll is widely used. The surface layer of the paper roll is formed by pressing and solidifying fibers such as wool and paper.

  By the way, as shown in FIGS. 1 and 2, the embossing device 10 is arranged on the downstream side of the embossing roll 20 and the backup roll 13, and information on the inspection uneven pattern 90 of the original fabric 70 to which the uneven pattern 40 is transferred. The sensor 15 is further provided for measuring in a non-contact state. In the present embodiment, the sensor 15 is configured by a gloss meter that can measure the glossiness of the inspection object based on the specular reflectance on the inspection object. The “glossiness” in this case is a glossiness measured in accordance with JIS 6007.

  Specifically, as shown in FIGS. 6 and 7, the sensor 15 has a light emitting unit 15a that emits light and a light receiving unit 15b that receives light. The light emitting unit 15 a and the light receiving unit 15 b are positioned so that the light from the light emitting unit 15 a is incident on the light receiving unit 15 b when it is specularly reflected on the inspection uneven pattern 90 of the original fabric 70. As a result, as shown in FIG. 6, when the roughness of the inspection uneven pattern 90 of the original fabric 70 is rough, the light from the light emitting portion 15a is scattered and reflected relatively strongly on the inspection uneven pattern 90, and the light receiving portion The amount of light incident on 15b decreases. In this case, the glossiness measured by the glossmeter takes a low numerical value. On the other hand, as shown in FIG. 7, when the inspection concavo-convex pattern 90 of the original fabric 70 is flattened, most of the light from the light emitting portion 15a is specularly reflected on the inspection concavo-convex pattern 90 and enters the light receiving portion 15b. The amount of incident light increases. In this case, the glossiness measured by the glossmeter takes a high numerical value. That is, the glossiness of the inspection uneven pattern 90 measured by the sensor 15 varies in relation to the degree of roughness of the inspection uneven pattern 90 (for example, surface roughness and uneven depth). For example, as shown in FIG. 8, the glossiness measured by the sensor 15 as a glossmeter, and the roughness of the rough surface of the inspection object (10-point average roughness Rz measured according to JISB0401) , Has a strong correlation. Therefore, it is possible to accurately measure information on the degree of roughness (degree of flattening) of the inspection concave-convex pattern 90 by the sensor 15 including a gloss meter in a non-contact state.

  As shown in FIG. 2, the embossing device 10 is a control device 11 connected to the sensor 15, and inspects the inspection concave / convex pattern 90 formed on the original fabric 70 based on the measurement value by the sensor 15. A control device 11 is further provided. The control device 11 determines whether or not the inspection unevenness pattern 90 formed on the original fabric 70 is flattened beyond a preset level, or whether or not it is flattened beyond a preset level. It comes to judge. The control device 11 is also connected to a rotational drive mechanism of the embossing roll 20, a rotational drive mechanism of the backup roll 13, and an original fabric supply device. And the control apparatus 11 can control rotation of the embossing roll 20, rotation of the backup roll 13, supply of the original fabric 70, etc. based on the measured value by the sensor 15.

  Next, the processed product 80 that can be manufactured by the embossing device 10 having the above-described configuration will be described.

As described above, the processed product 80 is manufactured by sandwiching the original fabric 70 between the embossing roll 20 and the backup roll 13 and forming an uneven shape on the surface of the original fabric 70. That is, the processed product 80 includes the original fabric 70 to which the uneven shape of the embossing mold surface 30 is transferred by embossing. Raw 70 is, for example, paper, and more specifically, may be composed of kraft paper having a 80g / m ² ~200g / m ² about basis weight. The thickness of the original fabric 70 can be set to several hundred μm, more specifically, about 25 μm to 500 μm.

  The original fabric 70 has an uneven pattern 85 and an inspection uneven pattern 90 arranged at a position shifted from the uneven pattern 85 along one direction on the original fabric 70. As described above, the inspection uneven pattern 90 is used to inspect the unevenness of the uneven pattern 35.

  As described above, the concavo-convex pattern 85 is formed by transferring the concavo-convex portion 35 of the embossed mold surface 30. Therefore, the uneven pattern 85 has an uneven shape corresponding to the uneven shape of the uneven portion 35 of the embossed mold surface 30 described above. As an example, when the processed product to be manufactured is a release paper (pattern paper) for synthetic leather, the uneven pattern 85 is configured to have a leather pattern. Similarly, the inspection uneven pattern 90 is formed by transferring the uneven pattern 40 on the embossing mold surface 30. Therefore, the inspection concave / convex pattern 90 has a concave / convex shape corresponding to the concave / convex shape of the concave / convex pattern 40 of the embossing mold surface 30 described above, and has a concave / convex shape different from the concave / convex pattern 35.

  Hereinafter, the inspection concave / convex pattern 90 will be described in detail mainly with reference to FIGS. 1, 2, 4, and 5, and all of them have a concave / convex shape corresponding to the concave / convex pattern 40 of the embossing mold surface 30. Will be easily understood. Further, as the unevenness of the processed product 80 described in the present case, “convex” and “concave” are used with reference to the surface of the original fabric 70 facing the embossed mold surface 30.

  As shown in FIGS. 1 and 2, the inspection concavo-convex pattern 30 is shifted from each other along the one direction (in this example, the width direction orthogonal to the longitudinal direction of the original fabric 70) on the original fabric 70. The first inspection pattern portion group 92 and the second inspection pattern portion group 96 are arranged in the first and second inspection pattern portions. The first inspection pattern portion group 92 and the second inspection pattern portion group 96 are arranged along the other direction (in this example, the longitudinal direction of the original fabric 70) on the original fabric 70 orthogonal to the one direction. A plurality of inspection pattern portions 93 and 97 are arranged, respectively.

  As shown in FIGS. 4 and 5, each of the inspection pattern portions 93 and 97 included in the first inspection pattern portion group 92 and the second inspection pattern portion group 96 includes a plurality of recesses 93a and 97a. Yes. The concave / convex shape of the inspection concave / convex pattern 90 is constituted by the concave portions 93a and 97a.

  The recesses 93a and 97a are arranged side by side along the other direction (the longitudinal direction of the original fabric) on the original fabric 70. Each of the recesses 93a and 97a has a concave shape in a triangular shape (strictly, an isosceles triangle) in a cross section orthogonal to one direction on the original fabric 70 (width direction of the original fabric). Further, as shown in FIGS. 1, 5, and 6, the recesses 93 a and 97 a extend in a groove shape along the one direction on the original fabric 70.

  As shown in FIGS. 5 and 6, in each of the inspection pattern portions 93 and 97, the plurality of concave portions 93a and 97a have the same shape, and the concave portions 93a and 97a are between the different inspection pattern portions 93 and 97. Have different shapes.

  As shown in FIG. 4, the ratio of the depth hb to the width wb in the cross-sectional triangle of the concave portion 93 (hb / wb) between the concave portions 93a included in different inspection pattern portions 93 in the first inspection pattern portion group 92. In the following description, they are also simply referred to as “aspect ratio of the recesses”), and the depths hb in the cross-sectional triangles of the recesses 93 are different from each other. In particular, as shown in FIG. 3, the first pattern portion group 42 of the embossing mold surface 30 has ten pattern portions 43. As a result, the first pattern portion for inspection 92 has 10 A recess 93a having different types of depth hb is included. Further, the maximum value of the depth hb of the concave portion 93a included in the first inspection pattern portion group 92 is the same as the maximum value of the depths of the concave portions constituting the concave / convex shape of the concave / convex pattern 85. .

  On the other hand, as shown in FIG. 5, the depth hb in the cross-sectional triangle of the recess 97a is the same between the recesses 97a included in different test pattern portions 97 in the second test pattern portion group 96, The ratio of the depth hb to the width wb (the aspect ratio of the recess (hb / wb)) in the cross-sectional triangle of 97a is different from each other. In particular, as shown in FIG. 3, the second pattern portion group 46 of the embossing mold surface 30 has ten pattern portions 47, and as a result, the second inspection pattern portion group 96 includes 10 pattern portions 47. Concave portions 97a having different types of aspect ratios (hb / wb) are included. In addition, the maximum value of the ratio of the depth hb to the width wb in the cross-sectional triangle of the concave portion 97a included in the second inspection pattern portion group 96 is the aspect ratio of the concave portion having a triangular cross-section included in the concave / convex pattern 85. It is the same as the maximum value.

  The aspect ratio of the concave portion 93a included in the first inspection pattern portion group 92 is, for example, a half value of the maximum value of the aspect ratio of the concave portion constituting the concave / convex shape of the concave / convex pattern 85, or the concave / convex pattern. It can be set to a substantially average value or the like of the aspect ratio of the concave portions constituting the concave / convex shape of 85. In addition, the depth of the concave portion 97a included in the second inspection pattern portion group 96 is, for example, a value that is half of the maximum value of the depth of the concave portion constituting the concave / convex shape of the concave / convex pattern 85, or the concave / convex pattern. It can be set to a substantially average value or the like of the depths of the recesses constituting the 85 uneven shape.

  The depth hb of the concave and convex portions to be transferred and the aspect ratio (hb / wb) of the concave portions are two parameters that can have a significant influence on the transfer efficiency of the concave and convex shapes to the original fabric 70. The inspection concave / convex pattern 90 has an uneven shape including various depths and aspect ratios that can be included in the uneven shape of the uneven pattern 85. That is, the inspection concave / convex pattern 90 formed on the raw fabric 70 by the concave / convex pattern 40 has a concave / convex shape very highly related to the concave / convex shape of the concave / convex pattern 85 formed on the raw fabric 70 by the concave / convex portion 35. ing. The transfer efficiency when the concavo-convex pattern 40 is transferred as the inspection concavo-convex pattern 90 to the original fabric 70 has a strong correlation with the transfer efficiency when the concavo-convex portion 35 is transferred as the concavo-convex pattern 85 to the original fabric 70. It becomes like this. Therefore, by inspecting the inspection concavo-convex pattern 90 formed on the original fabric 70 by the concavo-convex pattern 40, the concavo-convex shape of the concavo-convex pattern 85 formed on the original fabric 70 by the concavo-convex portion 35 and having a complicated concavo-convex shape can be accurately obtained. It becomes possible to confirm.

  In addition, although the various points of the uneven | corrugated shape formed in the original fabric 70 have been demonstrated in detail, various points regarding the above-described shape, for example, the cross-sectional shape of the recess (such as a triangular shape), the depth of the recess, The aspect ratio and the like do not necessarily require strictness, but it is sufficient to consider them as approximate ones. For example, a deviation from the above description due to a processing error or the like may be ignored.

  In addition, as shown in FIG. 2, the registration mark portion 37 formed at a predetermined position with respect to the concavo-convex pattern 40 on the embossed mold surface 30 causes the processed product 80 to have a position of the concavo-convex pattern 90 for inspection. A registration mark 87 for identifying the image is transferred. The registration mark 87 includes a plurality of inspection pattern portions 93 included in the first inspection pattern portion group 92 and a plurality of inspection pattern portions 97 included in the second inspection pattern portion group 96, and the original fabric 70. Are arranged side by side in the other direction (longitudinal direction of the original fabric). The registration marks 87 identify the positions of the plurality of inspection pattern portions 93 included in the first inspection pattern portion group 92 and the plurality of inspection pattern portions 97 included in the second inspection pattern portion group 96. It can be made easier. Thereby, handling of the inspection uneven pattern 90 can be facilitated.

  Next, an example of a method for manufacturing the processed product 80 by forming the uneven pattern 85 on the original fabric 70 using the embossing device 10 having the above-described configuration will be described.

  First, a step of setting a quality criterion for the inspection uneven pattern 90 is performed. In this process, a preliminary idle operation process in which the embossing roll 20 and the backup roll 13 are idly operated, a test embossing process in which a concavo-convex shape is formed on the original fabric 70, and a determination for determining a quality criterion for the inspection concavo-convex pattern 90 The standard determination process is sequentially performed.

  Of these, in the preliminary idle operation step, the embossing roll 20 and the backup roll 13 are idled as shown in FIG. Here, “idle operation (idling)” means that the embossing roll 20 and the backup roll 13 are rotated without the raw fabric 70 being supplied between the embossing roll 20 and the backup roll 13. During the idling operation, the embossing mold surface 30 of the embossing roll 20 comes into contact with the outer peripheral surface of the backup roll 13, and the uneven convex portion of the embossing mold surface 30 presses the outer peripheral surface of the backup roll 13. At this time, it is preferable that the positional relationship between the embossing roll 20 and the backup roll 13 is set to substantially the same conditions as when embossing is actually performed on the original fabric 70.

  As described above, the surface layer of the backup roll 13 is configured to be deformable and configured to maintain the deformed state for at least a certain period. For this reason, in this preliminary idle operation step, the uneven shape of the uneven portion 35 of the emboss mold surface 30 and the uneven shape of the uneven pattern 40 are gradually transferred to the surface layer (outer peripheral surface) of the backup roll 13. This process is performed until the deformation of the surface layer of the backup roll 13 is substantially saturated and the surface layer of the backup roll 13 maintains a substantially constant shape.

  Next, the test embossing process will be described. In this step, as shown in FIG. 10, the original fabric 70 is placed between the embossing roll 20 and the backup roll 13 while the embossing roll 20 and the backup roll 13 are rotated. )). As a result, a concavo-convex pattern 85 corresponding to the concavo-convex portion 35 of the embossing mold surface 30 is formed on the original fabric 70, and an inspection concavo-convex pattern 90 corresponding to the concavo-convex pattern 40 of the embossing mold surface 30 is formed on the original fabric 70. Then, the test processed product 81 is formed.

  During the test embossing process, information on the degree of unevenness of the inspection unevenness pattern 90 of the test workpiece 81 continuously manufactured by the sensor 15 disposed downstream of the embossing roll 20 and the backup roll 13 is provided. It will be collected. As described above, the sensor 15 is configured as a non-contact type gloss meter. Therefore, it is possible to collect information on the inspection concave / convex pattern 90 without interrupting continuous processing of the original fabric 70 by the embossing device 10. In particular, the sensor 15 is a gloss meter, and can instantaneously measure the gloss level of the test unevenness portion 90 of the test workpiece 81. Therefore, the information of the inspection uneven pattern 90 can be continuously collected, and thereby included in the first inspection pattern portion group 92 and the second inspection pattern portion group 96 and sequentially formed. Information on each of the inspection pattern portions 93 and 97 can be collected. In addition, since the register mark 87 is provided on the original fabric 70, it is also possible to accurately identify which inspection pattern portions 93 and 97 the measurement result obtained by the sensor 15 corresponds to. is there.

  By the way, in the test embossing process, an original fabric 70 having a certain thickness is located between the embossing roll 20 and the backup roll 13. Therefore, the pressure applied to the outer peripheral surface (surface layer) of the backup roll 13 from the embossing mold surface 30 of the embossing roll 20 during the test embossing process is averaged as compared with the idle operation process. For this reason, as the test embossing process proceeds, the uneven shape corresponding to the uneven shape of the embossing mold surface 30 formed on the outer peripheral surface (surface layer) of the backup roll 13 during the idling operation step is gradually flattened. It becomes gentle and becomes gentle. Further, along with the flattening of the concavo-convex shape of the outer peripheral surface of the backup roll 13 that functions as a female mold, the concavo-convex portion 35 and the concavo-convex pattern 40 of the embossed mold surface 30 cannot be accurately transferred to the original fabric 70. . That is, as the test embossing process proceeds, the uneven shape of the uneven pattern 85 and the uneven shape of the inspection uneven pattern 90 formed on the original fabric 70 are gradually flattened.

  Therefore, the value of the glossiness at the portion of the inspection uneven pattern 90 measured by the sensor 15 also changes as the test embossing process proceeds. Specifically, the gloss value measured by the sensor 15 for the inspection uneven pattern 90 increases with the progress of the test embossing process. As an example, FIG. 11 shows changes in the measured value of the glossiness at each pattern portion 93 included in the first inspection pattern portion group 92.

  Next, the process of determining the quality criteria for the inspection uneven pattern 90 will be described. In this step, the uneven shape of the uneven pattern 85 of the manufactured test work 81 is actually inspected. As described above, the concavo-convex shape of the concavo-convex pattern 85 formed on the original fabric 70 is flattened as the test embossing process proceeds. Eventually, the concavo-convex shape of the concavo-convex pattern 85 is flattened to such an extent that standards set in accordance with the application of the processed product 80 cannot be satisfied. Here, the concavo-convex pattern 85 produced on the original fabric 70 in the test embossing process is inspected, and a portion where the concavo-convex pattern 85 shifts from a good quality state to a poor quality is investigated. The state of the uneven shape of the formed inspection uneven pattern 90 is specified.

  As described above, the inspection concave / convex pattern 90 has the same range as the concave / convex pattern 85 with respect to the concave / convex gap (depth, height) and concave / convex aspect ratio. The transfer efficiency of the concavo-convex shape greatly depends on the gap (depth, height) of the concavo-convex shape to be transferred and the aspect ratio of the concavo-convex shape. Therefore, the progress of the flattening of the inspection concave / convex pattern 90 accompanying the progress of the embossing process proceeds with a strong correlation with the progress of the flattening of the concave / convex pattern 85. Further, as described above, the gloss level measured by the sensor 15 has a strong correlation with the degree of roughness (the degree of flattening) (see FIG. 8). For this reason, if the relationship between the progress of flattening of the concavo-convex pattern 85 accompanying the progress of the embossing process and the change in the glossiness of the inspection concavo-convex pattern 90 accompanying the progress of the embossing process is investigated, By measuring the glossiness of the concavo-convex pattern for inspection 90 to be formed, it becomes possible to specify the degree of flatness (degree of roughness) of the concavo-convex shape of the concavo-convex pattern 85.

  Here, furthermore, the value of the glossiness of the inspection concave / convex pattern 90 when the concave / convex pattern 85 does not satisfy the required quality standard is used to inspect the inspection concave / convex pattern 90 that is performed instead of performing the inspection of the concave / convex pattern 85. Is determined as a criterion for the quality of the inspection uneven pattern 90. As an example, when the concavo-convex pattern 85 formed after 6 hours from the start of the embossing process becomes poor in quality, the glossiness of the concavo-convex pattern for inspection 90 is assumed to be as shown in FIG. 11 as the embossing process proceeds. If it changes as shown, the gloss of each inspection pattern portion 93a, 97a of the inspection uneven pattern 90 formed 6 hours after the start of the embossing process is used as a criterion for determining the quality of the inspection uneven pattern 90. The degree value can be used as a determination criterion for each of the inspection pattern portions 93a and 97a.

  In this way, the glossiness of the inspection concave / convex pattern 90 produced at the same time as the concave / convex pattern 85 that does not satisfy the predetermined quality standard is specified, and is set in the control device 11 as a criterion for determining whether the inspection concave / convex pattern 90 is good or bad. Is done.

  As described above, after the determination criteria for pass / fail of the inspection concave / convex pattern 90 is set, the first empty operation process in which the embossing roll 20 and the backup roll 13 are operated in an idle state, and the unevenness shape is formed on the original fabric 70. The first embossing process and the second idle operation process in which the embossing roll 20 and the backup roll 13 are idled are sequentially performed.

  In the first idling operation step, the embossing roll 20 and the backup roll 13 are idling, and the irregular shape corresponding to the irregularities 35 and the irregular pattern 40 formed on the embossing mold surface 30 of the embossing roll 20 It is formed again on the outer peripheral surface. Specifically, as shown in FIG. 9, the embossing roll 20 and the backup roll 13 are idled without being supplied with the raw fabric 70 between the embossing roll 20 and the backup roll 13. Accordingly, the embossing mold surface 30 of the embossing roll 20 comes into contact with the outer peripheral surface of the backup roll 13, and the convex and concave portions of the embossing mold surface 30 press the outer peripheral surface of the backup roll 13. Thereby, the uneven shape of the uneven portion 35 of the emboss mold surface 30 and the uneven shape of the uneven pattern 40 are gradually transferred to the surface layer (outer peripheral surface) of the backup roll 13. And this 1st idle operation process is implemented until the deformation | transformation of the surface layer of the backup roll 13 becomes substantially saturated, and the surface layer of the backup roll 13 can maintain a substantially constant shape.

  Next, in the first embossing process, as shown in FIG. 10, the embossing roll 20 is removed from the original fabric supply device (not shown) while the embossing roll 20 and the backup roll 13 are rotated. And supplied to the backup roll 13. As a result, a concavo-convex pattern 85 corresponding to the concavo-convex portion 35 of the embossing mold surface 30 is formed on the original fabric 70, and an inspection concavo-convex pattern 90 corresponding to the concavo-convex pattern 40 of the embossing mold surface 30 is formed on the original fabric 70. The processed product 80 is formed.

  During the test embossing process, the inspection concave / convex pattern 90 of the workpiece 80 continuously manufactured is inspected by the sensor 15 disposed on the downstream side of the embossing roll 20 and the backup roll 13. Specifically, using the sensor 15, the glossiness at the portion of the inspection uneven pattern 90 of the processed product 80 is measured. As described above, the sensor 15 is configured as a non-contact type gloss meter. Therefore, it is possible to collect information on the inspection concave / convex pattern 90 without interrupting continuous processing of the original fabric 70 by the embossing device 10. In particular, according to the sensor 15 comprising a gloss meter, information on the inspection uneven pattern 90 can be continuously collected. As a result, information of each of the inspection pattern portions 93 and 97 included in the first inspection pattern portion group 92 and the second inspection pattern portion group 96 and sequentially formed is continuously collected. Can do. Further, since the register mark 87 is provided on the original fabric 70, it is possible to accurately identify which inspection pattern portions 93 and 97 the measurement result obtained by the sensor 15 corresponds to.

  The measured value of the glossiness is transmitted from the sensor 15 to the control device 11. As described above, the measured value of the glossiness changes with the progress of the embossing process and gradually increases. The control device 11 compares the measured glossiness value with a predetermined criterion value for the quality of the inspection uneven pattern 90. When the determination criterion is set as the allowable maximum value of the inspection concave / convex pattern 90, the control device 11 determines whether the gloss value of the inspection concave / convex pattern 90 that is sequentially measured exceeds the determination criterion. Judging. When it is determined that the gloss value of the inspection uneven pattern 90 exceeds the determination criterion, the first embossing process is terminated. Similarly, when the determination criterion is set as an unacceptable minimum value of the inspection concave / convex pattern 90, the controller 11 determines that the gloss value of the inspection concave / convex pattern 90 that is sequentially measured is equal to or greater than the determination criterion. Judge whether there is. When it is determined that the gloss value of the inspection uneven pattern 90 is greater than or equal to the criterion, the first embossing process is terminated.

  In other words, by inspecting the state of the concavo-convex shape of the inspection concavo-convex pattern 90, it is determined whether or not the concavo-convex pattern 85 of the processed product 80 has been flattened to an extent that does not satisfy the quality standard. And, when it is considered that the uneven pattern 85 of the processed product 80 does not satisfy the quality standard, in other words, when the uneven shape of the outer peripheral surface of the backup roll 13 functioning as a female mold is considered to be too flat, The first embossing process is finished, and the second idling process is started.

  In the second idling operation step, the embossing roll 20 and the backup roll 13 are idly operated, and a female mold is put into the outer peripheral surface (surface layer) of the backup roll 13 again. That is, the concavo-convex shape corresponding to the concavo-convex portion 35 and the concavo-convex pattern 40 formed on the embossing mold surface 30 of the embossing roll 20 is formed again on the outer peripheral surface of the backup roll 13. This step is performed until the deformation of the surface layer of the backup roll 13 is substantially saturated and the surface layer of the backup roll 13 can maintain a substantially constant shape.

  Thereafter, a second embossing step and a third idle operation step, and optionally a further embossing step and an idle operation step are performed in the same manner as described above. During the subsequent embossing process, the inspection concave / convex pattern 90 formed on the original fabric 70 is inspected in the same manner as the first embossing process described above. When it is determined that the inspection result of the inspection uneven pattern 90 is defective, the embossing process ends. Then, the idle operation step is performed, and the uneven shape corresponding to the uneven shape of the embossed mold surface 30 is formed again on the outer peripheral surface (surface layer) of the backup roll 13.

  According to the present embodiment as described above, the relationship between the change in the concavo-convex shape of the concavo-convex pattern 85 with the passage of the embossing time and the change in the concavo-convex shape of the test concavo-convex pattern 90 is investigated in advance. deep. And based on this investigation result, it becomes possible to confirm the uneven shape of the uneven pattern 85 by inspecting the uneven shape of the inspection uneven pattern 90. Thereby, by inspecting the inspection concave / convex pattern 90 formed on the original fabric 70, the progress of the flattening of the concave / convex shape formed on the backup roll 13 that causes the flattening of the concave / convex pattern 85 is confirmed. be able to. That is, the flatness of the backup roll 13 can be confirmed without inspecting the uneven pattern 85 that may have a complicated uneven shape and the inspection is extremely complicated and may take a long time. Further, unlike the concave / convex pattern 85 formed on the original fabric 70, the concave / convex pattern of the inspection concave / convex pattern 90 can be a simplified pattern. Therefore, the inspection of the inspection uneven pattern 90 and the inspection of the uneven shape formed on the backup roll 13 can be performed easily with high accuracy. As a result, it is possible to accurately detect the situation that requires the insertion into the backup roll 13 and to avoid unnecessary operation stop of the embossing device 10. Therefore, the embossing device 10 can be operated at a high operation rate, and the original fabric 70 can be embossed with excellent processing efficiency. Moreover, the processed product 80 in which the uneven pattern 85 having a desired uneven shape is formed can be stably manufactured.

  Further, according to the present embodiment, the inspection concave / convex pattern 90 is inspected in a non-contact manner. Therefore, it is not necessary to stop the embossing device 10 in order to inspect the inspection uneven pattern 90. Furthermore, the inspection uneven pattern 90 can be inspected in-line to confirm the flattening of the uneven shape formed on the backup roll 13. Thereby, the embossing apparatus 10 can be operated at a very high operation rate, and the original fabric 70 can be embossed with extremely excellent processing efficiency.

  Furthermore, according to the present embodiment, the glossiness of the inspection concave / convex pattern 90 is inspected in a non-contact manner with a gloss meter, and the presence / absence of flattening of the concave / convex shape formed on the backup roll 13 is confirmed. ing. According to such a method, it is possible to continuously inspect the inspection concave / convex pattern 90 which is sequentially formed on the original fabric 70 extending in a strip shape. Thereby, the change of the uneven | corrugated shape formed in the backup roll 13 can be confirmed continuously. For this reason, it is possible to detect the case where it is necessary to mold into the backup roll 13 very accurately, and to operate the embossing device 10 at an extremely high operation rate.

  Further, in the present embodiment, the concave / convex pattern 40 of the embossing mold surface 30 has a plurality of convex portions 43 a and 47 a arranged side by side along the circumferential direction of the embossing roll 20. Further, the convex portions 43 a and 47 a have a triangular shape in a cross section orthogonal to the rotation axis L <b> 1 of the embossing roll 20. Further, the convex portions 43 a and 47 a extend along the rotation axis L <b> 1 of the embossing roll 20. The inspection concavo-convex pattern 90 formed on the original fabric 70 by the concavo-convex pattern 40 having the convex portions 43a and 47a has a very simplified concavo-convex shape. Therefore, the flattening of the uneven shape of the inspection uneven pattern 90 formed on the original fabric 70 can be easily and accurately confirmed by various methods. As a result, it is possible to detect the case where it is necessary to mold into the backup roll 13 very accurately, and to operate the embossing device 10 at an extremely high operation rate.

  Furthermore, according to the present embodiment, the inspection concavo-convex pattern 90 formed on the original fabric 70 includes the concavo-convex shapes of various aspect ratios formed on the original fabric 70 as the concavo-convex pattern 85 and the concavo-convex pattern 85 on the original fabric 70. The concavo-convex shapes corresponding to the concavo-convex shapes of various depths formed as described above are included. The aspect ratio of the concavo-convex shape and the depth of the concavo-convex shape are the two most important parameters governing how accurately the concavo-convex shape of the embossed mold surface 30 is transferred to the original fabric 70. Therefore, by inspecting the concavo-convex shape of the inspection concavo-convex pattern 90, it can be determined very accurately whether the concavo-convex pattern 85 has a desired concavo-convex shape. As a result, it is possible to detect the case where it is necessary to mold into the backup roll 13 very accurately, and to operate the embossing device 10 at an extremely high operation rate.

  Various modifications can be made to the above-described embodiment within the scope of the present invention.

  For example, in the embodiment described above, an example in which the first pattern portion group 42 and the second pattern portion group 46 of the concavo-convex pattern 40 are adjacently disposed along one direction on the embossing mold surface 30. Although shown, it is not limited to this. For example, the uneven portion 35 may be arranged between the first group of pattern portions 42 and the second pattern portion group 46 along one direction on the embossed mold surface 30. In this case, a first inspection pattern portion group 92 formed corresponding to the first pattern portion group 42 and a second inspection pattern portion formed corresponding to the second pattern portion group 46. The group 96 is arranged so as to be separated along one direction on the original fabric 70.

  In the above-described embodiment, an example in which the uneven pattern 40 of the embossed mold surface 20 includes a first group of pattern portions 42 and a second pattern portion 46 each having a plurality of pattern portions is shown. However, it is not limited to this.

  For example, the concavo-convex pattern 40 of the embossing mold surface 20 may be composed of only a plurality of pattern portions arranged in a line along the other direction of the embossing mold surface 20 (circumferential direction of the embossing roll 20). In this example, each pattern portion may include a plurality of convex portions, and the plurality of convex portions may have the same shape in each pattern portion, while the convex portions may have different shapes between different pattern portions. In this case, between the convex parts included in different pattern parts, the ratio of the height to the base length in the sectional triangle of the convex part (the aspect ratio of the convex part) is the same, and the height in the sectional triangle of the convex part May be different from each other. Alternatively, between the convex portions included in different pattern portions, the heights of the convex cross-section triangles are the same, and the ratio of the height to the base length in the convex cross-sectional triangle (the aspect ratio of the convex portions) is They may be different from each other.

  In this way, the inspection uneven pattern 90 formed on the original fabric 70 is arranged in a line along the other direction (the longitudinal direction of the original fabric) on the original fabric 70 in accordance with the modification of the uneven pattern. It consists of only a plurality of inspection pattern portions. Each inspection pattern portion may include a plurality of recesses, and the plurality of recesses in each inspection pattern portion may have the same shape, while the protrusions may have different shapes between different pattern portions. In this case, the ratio of the depth to the width in the cross-sectional triangle of the concave portion (the aspect ratio of the concave portion) is the same between the concave portions included in different inspection pattern portions, and the depth in the cross-sectional triangle of the concave portion is different from each other. May be. Alternatively, between the recesses included in different inspection pattern portions, the depths of the cross-sectional triangles of the recesses are the same, and the ratio of the depth to the width (the aspect ratio of the recesses) in the cross-sectional triangle of the recesses is different from each other. Also good.

  Even in such a modified example, it is very accurately determined whether or not the uneven pattern 85 of the processed product 80 has the desired uneven shape by inspecting the uneven shape of the inspection uneven pattern 90 of the processed product 80. can do. As a result, it is possible to detect the case where it is necessary to mold into the backup roll 13 very accurately, and to operate the embossing device 10 at an extremely high operation rate.

  Furthermore, although the uneven pattern part 40 of the embossing type | mold surface 30 showed the example which has several pattern parts 43 and 47 which have mutually different uneven | corrugated shape in embodiment mentioned above, it is not restricted to this. The concavo-convex pattern portion 40 of the embossed mold surface 30 may be configured, for example, by arranging convex portions having the same shape at regular intervals. In this case, the inspection concave / convex pattern 90 formed on the original fabric 70 has a concave / convex shape in which concave portions having the same shape are arranged at regular intervals.

  Further, in the above-described embodiment, the example in which the sensor 15 is configured as a gloss meter and configured to measure the gloss level of the inspection concave / convex pattern 90 has been described, but the present invention is not limited thereto. For example, the sensor may be configured as a displacement measuring device, in particular as a laser displacement measuring device. According to the sensor composed of the displacement measuring device, the inspection concave / convex pattern can be inspected by measuring the concave / convex shape of the inspection concave / convex pattern formed on the original fabric in a non-contact manner. The control device 11 performs inspection when the measured uneven shape is flattened beyond a preset level, or when the measured uneven shape is flattened beyond a preset level. The uneven pattern for use can be determined to be defective.

  Note that the inspection concave / convex pattern 90 continuously formed on the original fabric 70 extending in a belt shape can also be inspected continuously by a sensor comprising a displacement measuring device. Therefore, it is possible to continuously check the change in the uneven shape formed on the backup roll 13. As a result, it is possible to detect the case where it is necessary to mold into the backup roll 13 very accurately, and to operate the embossing device 10 at an extremely high operation rate.

  Furthermore, the method for setting the quality determination criteria for the inspection concave / convex pattern described in the above embodiment is merely an example, and other methods may be used to set the quality determination criteria for the inspection concave / convex pattern. .
