Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a pair of rolls are used as conveying rolls for conveying a thin conveyed object such as a film or a sheet, or when a pair of rolls are used as sandwiching rolls for sandwiching a thin conveyed object such as a film or a sheet, even a slight inclination may have a great influence on the conveyance. However, in the measuring device of Patent Document 1, in order to measure substantially the same position in the axial direction of a pair of rolls, when the roll is slightly inclined and the measuring position is close to the base point of the inclination, the displacement amount from the reference position (parallel position) of the measuring position is small, and there is a problem that the inclination of the roll cannot be accurately detected.

[0005] Therefore, the present invention aims to provide a measuring device that can measure the inclination of a roll to be measured relative to a reference roll more accurately than conventional devices. [Means for solving the problem]

[0006] One aspect of the present invention for solving the above-mentioned problems is a measuring device for measuring the inclination of a roll to be measured using a reference roll that is spaced apart in a first direction relative to the roll to be measured, the device comprising: a first extension portion; a second extension portion extending perpendicular to the extension direction of the first extension portion from the first extension portion; a mounting portion provided on the first extension portion, which is attached so that the first extension portion extends in a first direction relative to the reference roll and the first extension portion straddles the reference roll and the roll to be measured; and a first measuring unit that is movable relative to the second extension portion in the extension direction of the second extension portion, wherein the first measuring unit comprises a first measuring portion for measuring the position of the roll to be measured in a first direction and / or a second measuring portion for measuring the position of the roll to be measured in a second direction perpendicular to the first direction.

[0007] According to this configuration, since the first measuring unit can be moved relative to the extension direction of the second extension, measurements can be taken at a position far from the position of the first extension of the roll to be measured in the extension direction of the second extension, that is, at a position where the displacement from the base point of the tilt is large if the roll to be measured is tilted, and even slight tilts can be detected. Furthermore, since the first measuring unit can be moved relative to the extension direction of the second extension, measurements can be taken at multiple locations in the extension direction of the second extension, allowing for more reliable detection of tilt.

[0008] A preferred configuration is that the first measuring unit comprises the first measuring section and the second measuring section.

[0009] A preferred configuration is that the first measuring unit comprises the first measuring section and a second measuring unit that is movable relative to the second stretching section in the stretching direction of the second stretching section, the second measuring unit comprising a third measuring section for measuring the position of the roll to be measured in the first direction.

[0010] A preferred configuration is that the first measuring unit comprises the first measuring section, the first measuring unit has a first position adjustment section that is movable in the first direction relative to the second stretching section, the first measuring unit brings the first position adjustment section into contact with the outer circumferential surface of the roll to be measured, and measures the position of the roll to be measured in the first direction via the first position adjustment section.

[0011] The aspects described above can be dependent on each other, refer to some of their components, or substitute for some of their components, as long as they fall within the technical scope of the present invention. [Effects of the Invention]

[0012] According to the present invention, the inclination of the roll to be measured relative to the reference roll can be measured more accurately than in the conventional method. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described in detail. Unless otherwise specified, the positional relationships of front, back, left, right, up, and down are based on FIG. 1. That is, the case where the measuring device 1 is used for the reference roll 200 and the measurement target roll 201 arranged side by side in the vertical direction (the first direction X) is taken as a reference.

[0015] As shown in FIG. 1, the measuring device 1 according to the first embodiment of the present invention measures the inclination of the measurement target roll 201 with respect to the reference roll 200 between the reference roll 200 and the measurement target roll 201 arranged at intervals in the first direction X (vertical direction, longitudinal direction). As shown in FIG. 2, the measuring device 1 includes a main body portion 2, a first measurement unit 3, a second measurement unit 5, and position regulating portions 6a and 6b.

[0016] <Main body portion 2> As shown in FIGS. 2 and 3, the main body portion 2 is a "T" - shaped portion when viewed from the front, and includes a first extension portion 10 and a second extension portion 11.

[0017] (First extension portion 10) As shown in FIG. 1, the first extension portion 10 is a portion extending in the first direction X, and is a portion installed across the reference roll 200 and the measurement target roll 201 during measurement. As shown in FIG. 2, the first extension portion 10 includes a first main body portion 20 and a mounting portion 21.

[0018] As shown in FIG. 2, the first main body portion 20 is a long plate - shaped portion having a width in the third direction Z (lateral direction, perpendicular to the first direction X and also perpendicular to the second direction Y) and extending with a length in the first direction X, and has a first main surface 22 and a second main surface 23.

[0019] As shown in Figure 2, the mounting portion 21 is provided at the end of the first extension portion 10 in the longitudinal direction (first direction X), and is attached to the reference roll 200 by contacting the reference roll 200 from at least two directions. The mounting portion 21 is L-shaped when viewed from the side and comprises a first wall portion 25 and a second wall portion 26. The first wall portion 25 is a plate-like portion that is in surface contact with and adhered to the first main surface 22 of the first main body portion 20. The second wall portion 26 is a vertical wall portion that rises from the outer end of the first wall portion 25 in the first direction X. The second wall portion 26 extends in a direction intersecting the first wall portion 25, and in this embodiment, it is upright relative to the first wall portion 25.

[0020] (Second extension part 11) The second extension portion 11 is a part that extends in the second direction Y (the axial direction of the reference roll 200), and as shown in Figure 2, it comprises a second main body portion 30 and extension side rail portions 31a and 31b.

[0021] As shown in Figure 2, the second main body portion 30 is a long plate-shaped portion that has width in the first direction X and length in the third direction Z, and has a first main surface 32 and a second main surface 33. As shown in Figures 2 and 3, the second main body portion 30 is connected to the intermediate portion of the first main body portion 20 of the first extension portion 10, overlapping in the thickness direction, and extends in a direction perpendicular to the extension direction of the first main body portion 20 of the first extension portion 10. In other words, the second main body portion 30 intersects the first extension portion 10 in three dimensions on the second main surface 23 side of the first main body portion 20.

[0022] The second main body portion 30 is bonded to the first main body portion 20 by surface contact between its first main surface 32 and the second main surface 23 of the first main body portion 20, and is inseparably connected to the first main body portion 20 as a single unit. In this context, "indivisible as one" refers to a type of "unified" state, where, in the relationship between two simple components, they cannot be separated or detached unless destroyed.

[0023] As shown in Figure 2, the extension rail sections 31a and 31b are fixed to the first main surface 32 of the second main body section 30 and are rails that extend in the same direction as the extension direction of the second main body section 30, i.e., in the third direction Z. The extended rail sections 31a and 31b are support rails that support the first measuring unit 3 and the second measuring unit 5. The extension rail sections 31a and 31b are spaced apart in the first direction X and are parallel to each other.

[0024] <First Measurement Unit 3> As shown in Figure 4, the first measuring unit 3 includes a measuring body 50, a first position adjustment unit 51, and a second position adjustment unit 52.

[0025] (Measurement main unit 50) The measuring body 50 includes a base 60, a first measuring section 61, a second measuring section 62, first rail engagement sections 63a and 63b, a first unit-side rail section 65, and a second unit-side rail section 66.

[0026] The base portion 60 is L-shaped when viewed from the side, and as shown in Figure 4, it comprises a first bottom wall portion 70, a first vertical wall portion 71, a first holding portion 72, and a second holding portion 73. The first bottom wall portion 70 is a support wall portion that supports the second unit side rail portion 66, and is a plate-shaped wall portion that extends in the second direction Y. The first vertical wall portion 71 is a vertical wall portion that rises from the end of the first bottom wall portion 70 in the second direction Y, and is equipped with a housing hole 80 and a confirmation portion 81.

[0027] The accommodating hole 80 is a through-hole that penetrates the first vertical wall portion 71 in the thickness direction (second direction Y), and is capable of accommodating a portion of the second position adjustment portion 52. The accommodating hole 80, when viewed from the front, is in the shape of an inverted "T" and includes a first restricting hole portion 85 extending in a first direction X and a second restricting hole portion 86 extending in a third direction Z. The first restricting hole 85 is a hole that extends in the first direction X from the middle of the second restricting hole 86 in the third direction Z.

[0028] The confirmation section 81 is a part for confirming the scale of the second measuring section 62, and as long as the scale of the second measuring section 62 can be confirmed, it may be a notch or a hole as shown in Figure 4.

[0029] The first holding portion 72 is a part that holds the first measuring portion 61 so as to extend in the first direction X, and is supported from one side (the upper side) in the first direction X. The second holding portion 73 is a part that holds the second measuring portion 62 so as to extend in the second direction Y.

[0030] The first measuring unit 61 measures the position coordinates of the main body wall portion 110 of the first position adjustment unit 51 in the first direction X. The first measuring unit 61 can use, for example, a micrometer head, and can measure the position coordinates of the main body wall portion 110 of the first position adjustment unit 51 in the first direction X using the position coordinates of the measuring surface 75 in one direction. The first measuring unit 61 is capable of measuring position coordinates based on the amount of displacement relative to a preset reference position.

[0031] The second measuring unit 62 measures the position coordinates of the main body wall portion 120 of the second position adjustment unit 52 in the first direction X. The second measuring unit 62 can use, for example, a micrometer head, and can measure the position coordinates of the main body wall portion 120 of the second position adjustment unit 52 in the first direction X using the position coordinates of the measuring surface 76 in one direction. The second measuring unit 62 is capable of measuring position coordinates based on the amount of displacement relative to a preset reference position. In this embodiment, the second measuring unit 62 uses a reference position where the contact wall portion 121 of the second position adjustment unit 52 is in the same plane as the base portion 160 of the second measuring unit 5, and the inclination of the roll to be measured in the second direction Y can be measured by the amount of change in this reference position.

[0032] The engagement portions 63a and 63b for the first rail are fixed to the first vertical wall portion 71 as shown in Figure 4(b), and are portions that can engage with the extension side rail portions 31a and 31b, and are portions that allow the first measuring unit 3 to move along the extension side rail portions 31a and 31b in the extension direction (third direction Z) of the extension side rail portions 31a and 31b.

[0033] As shown in Figure 4, the first unit side rail portion 65 is a rail fixed to the base portion 60 and extending in the first direction X, and is a support rail that supports the first position adjustment portion 51 so that it can move in the first direction X.

[0034] The second unit side rail section 66, as shown in Figure 4, is a rail fixed to the first bottom wall section 70 and extending in the second direction Y, and is a support rail that supports the second position adjustment section 52 so that it can move in the second direction Y.

[0035] (First position adjustment section 51) The first position adjustment section 51 is a part that adjusts the position of the contact protrusion 112 that contacts the outer surface of the roll 201 to be measured in accordance with the position of the outer surface of the roll 201 to be measured. As shown in Figure 4, the first position adjustment unit 51 comprises a main body 100, engagement parts 101a and 101b for the adjustment-side rail, and a position fixing part 102. The main body portion 100 includes a main body wall portion 110, a vertical wall portion 111, and a contact projection portion 112. The main body wall portion 110 has a first main surface 115 which is the lower surface and a second main surface 116 which is the upper surface. The vertical wall portion 111 is a wall portion that rises in a direction intersecting (orthogonal in this embodiment) with respect to the main wall portion 110. The contact projection 112 is a projection that protrudes from the first main surface 115 of the main body wall 110, and is the part that comes into contact with the roll 201 to be measured during measurement. The contact projection 112 is a protrusion extending in the second direction Y.

[0036] The engaging portions 101a and 101b for the adjustment-side rail are provided on the vertical wall portion 111, as shown in Figure 4, and are portions that can engage with the first unit-side rail portion 65, and are portions that allow the first position adjustment portion 51 to move along the first unit-side rail portion 65 in the direction of extension of the first unit-side rail portion 65 (first direction X). The engaging parts 101a and 101b for the adjustment rail are arranged with a gap between them in the first direction X.

[0037] The position fixing portion 102 is a part that fixes the position of the first position adjustment portion 51 relative to the measuring body portion 50, and has a constricted portion. By constricting the constricted portion, a pressing piece (not shown) can press against a part of the first unit side rail portion 65, thereby restricting the movement of the first position adjustment portion 51 relative to the measuring body portion 50.

[0038] (Second position adjustment section 52) The second position adjustment section 52 is a part that adjusts the position of the contact wall portion 121 that contacts the outer surface of the roll 201 to be measured in accordance with the position of the outer surface of the roll 201 to be measured. As shown in Figure 4, the second position adjustment unit 52 includes a main body wall 120, a contact wall 121, an engagement part 122 for the adjustment side rail, and a fixing member 123.

[0039] The main body wall portion 120 has a first end face 125 and a second end face 126 facing the second direction Y. The first end face 125 is the end face on one end side in the second direction Y, and the second end face 126 is the end face on the opposite side from the first end face 125. The contact wall portion 121 is a wall portion that rises from the end of the main body wall portion 120 in the second direction Y (the end on the side of the first end face 125), and is a portion that has a contact surface 130 that comes into contact with the roll 201 to be measured during measurement.

[0040] The engagement portion 122 for the adjustment-side rail is a portion that can engage with the second unit-side rail portion 66, and is a portion that allows the second position adjustment portion 52 to move along the second unit-side rail portion 66 in the extension direction of the second unit-side rail portion 66 (second direction Y). The fixing member 123 is a member that fixes the contact wall portion 121 to the main body wall portion 120.

[0041] Here, we will explain the positional relationships of each part of the first measurement unit 3.

[0042] As shown in Figure 6, the first position adjustment unit 51 has adjustment-side rail engagement parts 101a and 101b that clamp the first unit-side rail part 65 of the measuring body unit 50, and is supported by the first unit-side rail part 65 of the measuring body unit 50 so as to be movable along the extension direction (first direction X) of the first unit-side rail part 65. The first position adjustment unit 51 is positioned so that the second main surface 116 of the main body wall 110 is in contact with or close to the measuring surface 75 of the first measuring unit 61.

[0043] The second position adjustment section 52 has an adjustment-side rail engagement section 122 that clamps the second unit-side rail section 66 of the measuring body section 50, and is supported by the second unit-side rail section 66 of the measuring body section 50 so as to be movable along the extension direction (second direction Y) of the second unit-side rail section 66. As shown in Figure 6, the second position adjustment unit 52 is positioned so that the second end face 126 of the main body wall 120 (the end face in the second direction Y and the end face opposite to the contact wall 121) is in contact with or close to the measuring surface 76 of the second measuring unit 62. In the second position adjustment section 52, the first regulating hole 85 of the housing hole 80 provided in the first vertical wall section 71 of the base section 60 is closed on one side in the second direction Y (the second measuring section 62 side) by the first rail engagement section 63b, and a part of the first end face 125 side and a part of the contact wall section 121 of the main body wall section 120 are arranged in the housing hole 80. Specifically, the second position adjustment section 52 has a contact wall portion 121 inserted into the first regulating hole portion 85 from the other side of the second direction Y (opposite side from the second measuring section 62), and the main body wall portion 120 is inserted into the second regulating hole portion 86. Therefore, the second position adjustment section 52 is only allowed to move linearly in the second direction Y by the housing hole 80, and movement in the first direction X and third direction Z is restricted, and movement toward the second measuring section 62 in the second direction Y is restricted by the second unit side rail portion 66. In the second position adjustment section 52, the first end face 125 of the main body wall 120 and the contact surface 130 of the contact wall 121 form the same plane and are flush.

[0044] <Second Measurement Unit 5> As shown in Figure 5, the second measurement unit 5 includes a measurement body 150 and a position adjustment unit 151.

[0045] (Measurement unit 150) The measuring body 150 comprises a base 160, a third measuring section 161, a third holding section 162, second rail engagement sections 163a and 163b, and a unit-side rail section 165.

[0046] The base portion 160 is a trapezoidal plate-like body when viewed from the front. The third measuring unit 161 measures the position coordinates of the main body wall portion 110 of the position adjustment unit 151 in the first direction X. The third measuring unit 161 can use, for example, a micrometer head, and can measure the position coordinates of the main body wall portion 110 of the position adjustment unit 151 in the first direction X using the position coordinates of the measuring surface 175 in one direction. The third measuring unit 161 is capable of measuring position coordinates based on the amount of displacement relative to a preset reference position. In this embodiment, the third measuring unit 161 has the same reference position as the first measuring unit 61. Specifically, the third measuring unit 161 uses as its reference position the position where the tip surface of the contact projection 112 of the first measuring unit 3 and the tip surface of the contact projection 112 of the second measuring unit 5 are on the same plane. Therefore, the inclination of the roll 201 to be measured in the first direction X can be measured by the difference between the measurement value of the first measuring unit 61 of the first measuring unit 3 and the measurement value of the third measuring unit 161 of the second measuring unit 5.

[0047] The third holding portion 162 is a part that holds the third measuring portion 161 so as to extend in the first direction X, and is supported from one side (upper side) in the first direction X.

[0048] The second rail engagement portions 163a and 163b are portions that can engage with the extension side rail portions 31a and 31b, and are portions that allow the second measuring unit 5 to move along the extension side rail portions 31a and 31b in the extension direction (third direction Z) of the extension side rail portions 31a and 31b.

[0049] The unit-side rail portion 165 is fixed to the base portion 160 and is a rail extending in the first direction X, and is a support rail that supports the position adjustment portion 151 so that it can move in the first direction X.

[0050] (Position adjustment section 151) Since the position adjustment section 151 is made of the same components as the first position adjustment section 51, the parts of the position adjustment section 151 are numbered in the same way as those of the first position adjustment section 51, and their explanation is omitted. In other words, the position adjustment unit 151, as shown in Figure 5, comprises a main body 100, engagement parts 101a and 101b for the adjustment-side rail, and a position fixing part 102.

[0051] Here, we will explain the positional relationships of each part of the second measurement unit 5.

[0052] As shown in Figure 7, the position adjustment unit 151 has adjustment-side rail engagement parts 101a and 101b that clamp the unit-side rail part 165 of the measuring body 150, and is supported by the unit-side rail part 165 of the measuring body 150 so as to be movable along the extension direction (first direction X) of the unit-side rail part 165. The position adjustment unit 151 is positioned opposite the measuring surface 175 of the third measuring unit 161 at a position where the second main surface 116 of the main body wall 110 is in contact with or close to it.

[0053] <Position regulation part 6a, 6b> As shown in Figure 2, the position regulating sections 6a and 6b are equipped with engaging sections 180a and 180b for the regulating rail and position fixing sections 181a and 181b.

[0054] (Engaging parts 180a, 180b for the regulating rail) The regulating rail engagement portions 180a and 180b are portions that can engage with the extending rail portions 31a and 31b, and are portions that allow the position regulating portions 6a and 6b to move along the extending rail portions 31a and 31b in the extension direction (third direction Z) of the extending rail portions 31a and 31b.

[0055] The position fixing parts 181a and 181b are parts that fix the positions of the position restricting parts 6a and 6b relative to the extension rail parts 31a and 31b, and have a constricted portion. By constricting the constricted portion, a pressing piece (not shown) can press against a part of the extension rail parts 31a and 31b, thereby restricting the movement of the position restricting parts 6a and 6b relative to the extension rail parts 31a and 31b.

[0056] Next, the positional relationships of each component of the measuring device 1 in this embodiment will be described.

[0057] As shown in Figures 6 and 7, the measuring units 3 and 5 are supported by the second extension section 11, with rail engagement portions 63a, 63b, 163a, and 163b clamping the extended rail portions 31a and 31b of the second extension section 11. As shown in Figure 2, the position regulating sections 6a and 6b are supported by the second extension section 11, with the regulating side rail engaging sections 180a and 180b clamping the extension side rail sections 31a and 31b of the second extension section 11. As shown in Figures 1 and 2, both measurement units 3 and 5 are located on the first extension section 10 side of the position regulating sections 6a and 6b, while the second measurement unit 5 is located on the first extension section 10 side of the first measurement unit 3. The measurement units 3 and 5 have their movement range in the third direction Z restricted by the position restricting parts 6a and 6b, and are unable to detach from the extension side rail parts 31a and 31b of the second extension part 11.

[0058] Next, we will explain an example of a recommended procedure and its positional relationship when measuring the inclination of the target roll 201 relative to the reference roll 200 using the measuring device 1.

[0059] First, the mounting portion 21 is engaged with the reference roll 200, and the roll to be measured 201 is brought into contact with or close to the base portion 160 of the second measuring unit 5 in the second direction Y.

[0060] At this time, the mounting portion 21 is engaged with the reference roll 200 such that the first extension portion 10 extends tangentially with respect to the axial direction of the reference roll 200. Furthermore, at this time, the mounting portion 21 has a first wall portion 25 and a second wall portion 26 that are perpendicular to each other, and these two wall portions engage with the outer circumferential surface of the reference roll 200. That is, the first wall portion 25 is in contact with the outer circumferential surface of the reference roll 200 from the outside in the second direction Y, and the second wall portion 26 is in contact with the outer circumferential surface of the reference roll 200 from the outside in the first direction X. Furthermore, at this time, the first stretched portion 10 extends across the reference roll 200 and the roll to be measured 201, and the second stretched portion 11 extends approximately parallel to the reference roll 200.

[0061] Next, the second position adjustment unit 52 of the first measuring unit 3 is moved in the second direction Y along the rail portion 66 on the second unit side so that the contact wall portion 121 contacts the outer circumferential surface of the roll 201 to be measured, and the position of the outer circumferential surface of the roll 201 to be measured in the second direction Y is measured using the second measuring unit 62 at the position where the roll 201 to be measured contacts the contact wall portion 121.

[0062] At this time, the roll to be measured 201 is positioned to straddle the base portion 160 of the second measuring unit 5 and the contact wall portion 121 of the first measuring unit 3. Furthermore, at this time, the contact wall portion 121 of the first measuring unit 3 extends tangentially with respect to the outer circumferential surface of the roll 201 to be measured. Furthermore, at this time, the second measuring unit 62 indirectly measures the position of the contact surface 130 of the contact wall 121, that is, the position of the outer circumferential surface of the roll 201 to be measured, by measuring the position of the second end face 126 of the second position adjustment unit 52.

[0063] Next, the first measuring unit 3 and the second measuring unit 5 are moved to the desired positions along the extended rail sections 31a and 31b.

[0064] Once the positions of the first measuring unit 3 and the second measuring unit 5 in the third direction Z are determined, the first measuring unit 3 is moved in the first direction X along the first unit side rail 65 so that the contact projection 112 of the first measuring unit 3 contacts the outer circumferential surface of the roll 201 to be measured, and the second measuring unit 5 is moved in the first direction X along the unit side rail 165 so that the contact projection 112 of the second measuring unit 5 contacts the outer circumferential surface of the roll 201 to be measured. Then, at the position where the roll to be measured 201 makes contact with the contact protrusions 112, 112 of the first measuring unit 3 and the second measuring unit 5, respectively, the position in the first direction X is measured using the first measuring unit 61 and the third measuring unit 161.

[0065] At this time, both the contact projection 112 of the first measuring unit 3 and the contact projection 112 of the second measuring unit 5 extend in the tangential direction to the roll 201 to be measured. Furthermore, at this time, the first measuring unit 61 indirectly measures the position of the tip surface of the contact projection 112, that is, the outer peripheral surface of the roll to be measured 201, by measuring the position of the second main surface 116 of the main body wall portion 110 of the first position adjustment unit 51 via the first position adjustment unit 51. Similarly, the third measuring unit 161 indirectly measures the position of the tip surface of the contact projection 112, i.e., the outer circumferential surface of the roll 201 to be measured, via the position adjustment unit 151 by measuring the position of the second main surface 116 of the main body wall portion 110 of the position adjustment unit 151.

[0066] As described above, the measuring device 1 can measure the inclination of the target roll 201 in the first direction X relative to the reference roll 200 by the difference in the measurement positions of the first measuring unit 61 and the third measuring unit 161, and can measure the inclination of the target roll 201 in the second direction Y by the measurement position of the second measuring unit 62.

[0067] According to the measuring device 1 of this embodiment, the device includes a first extension section 10, a second extension section 11 extending perpendicularly to the extension direction of the first extension section 10, a mounting section 21 provided on the first extension section 10 which attaches the first extension section 10 so that it extends in a first direction X relative to the reference roll 200 and the first extension section 10 straddles the reference roll 200 and the roll to be measured 201, and a first measuring unit 3 which is movable relative to the second extension section 11 in the extension direction of the second extension section 11. The first measuring unit 3 includes a first measuring section 61 which measures the position of the roll to be measured 201 in the first direction X and a second measuring section 62 which measures the position of the roll to be measured 201 in a second direction Y perpendicular to the first direction X. According to the measuring device 1 of this embodiment, since the first measuring unit 3 can be moved relative to the extension direction of the second extension portion 11, measurements can be taken at a position away from the position of the first extension portion 10 of the roll to be measured 201 in the extension direction of the second extension portion 11, that is, at a position where the amount of displacement from the base point of the inclination of the roll to be measured 201 is large if the roll to be measured 201 is inclined, and even slight inclinations can be detected.

[0068] In the measuring device 1 of this embodiment, the first measuring unit 3 is equipped with a first measuring section 61 and has a second measuring unit 5 that is movable relative to the second extending section 11 in the extending direction of the second extending section 11, and it is preferable that the second measuring unit 5 is equipped with a third measuring section 161 that measures the position of the roll to be measured 201 in a first direction X. This makes it possible to measure the inclination and displacement of the roll to be measured 201 between any positions.

[0069] In the measuring device 1 of this embodiment, the first measuring unit 3 is equipped with a first measuring section 61, and the first measuring unit 3 has a first position adjustment section 51 that is movable in a first direction X relative to the second stretching section 11, and it is preferable that the first measuring unit 3 brings the first position adjustment section 51 into contact with the outer circumferential surface of the roll to be measured 201, and measures the position of the roll to be measured 201 in the first direction X via the first position adjustment section 51. By doing so, the first measuring section 61 does not directly contact the roll to be measured 201, so it is possible to prevent damage such as scratches caused by the first measuring section 61 contacting the roll to be measured 201.

[0070] In the embodiment described above, both the inclination of the roll 201 to be measured in the first direction X and the inclination in the second direction Y relative to the reference roll 200 were measured, but the present invention is not limited thereto. Only the inclination of the roll 201 to be measured in the first direction X may be measured, or only the inclination of the roll 201 to be measured in the second direction Y may be measured.

[0071] In the embodiment described above, the mounting portion 21 was attached to the reference roll 200 by contacting the outer circumferential surface of the reference roll 200 from two directions, a first direction X and a second direction Y. However, the present invention is not limited to this. The mounting method of the mounting portion 21 is not particularly limited as long as it can be attached to the reference roll 200. The mounting portion 21 may also be attached to the reference roll 200 by surrounding the outer circumferential surface of the reference roll 200 from three directions, a first direction X, a second direction Y, and a third direction Z.

[0072] In the embodiments described above, each measuring unit 61, 62, and 161 indirectly measured the position of the outer surface of the roll 201 to be measured via the position adjustment units 51, 52, and 151, but the present invention is not limited thereto. Each measuring unit 61, 62, and 161 may directly measure the position of the outer surface of the roll 201 to be measured.

[0073] In the embodiment described above, the positions of two outer surfaces of the roll 201 to be measured were measured in the axial direction using two measuring units 3 and 5, but the present invention is not limited thereto. The positions of the outer surfaces of the roll 201 to be measured may be measured using only the first measuring unit 3, or the positions of the outer surfaces of the roll 201 to be measured may be measured using three or more measuring units.

[0074] In the embodiment described above, the first extension portion 10 and the second extension portion 11 were bonded to each other, and the position of the second extension portion 11 in the first direction X was fixed. However, the present invention is not limited thereto. The position of the second extension portion 11 in the first direction X may be variable by rails or the like.

[0075] In the embodiment described above, the reference roll 200 and the roll to be measured 201 were arranged in the vertical direction (first direction X), but the present invention is not limited thereto. The direction in which the reference roll 200 and the roll to be measured 201 are arranged side by side is not particularly limited. That is, the reference roll 200 and the roll to be measured 201 may be arranged in directions other than the vertical direction (first direction X).

[0076] In the embodiments described above, the components can be freely substituted or added between each embodiment, as long as they fall within the technical scope of the present invention. [Explanation of symbols]
