Description

[0001]
BACKGROUND OF THE INVENTION
This invention measures the uneven state of the mirror surface of a winding roll formed by continuously winding a continuous thin strip (hereinafter referred to as “web”) such as paper, film, metal foil or the like. The present invention relates to an unevenness measuring device for a mirror surface of a take-up roll.
[0002]
[Prior art]
The winder process for winding the web is performed by continuously winding the manufactured and traveling web around the core material. In the case of meandering during traveling, or in the case of paper, etc. Due to a change or the like, the mirror surface may not be uniform and irregularities may be formed on the mirror surface. When the take-up roll is shipped as a product, if the unevenness of the mirror surface is not within a predetermined size range, problems may occur in the process of processing the take-up roll by printing, cutting, etc. Therefore, the winding roll becomes unsuitable as a product. For this reason, measuring and managing the unevenness of the mirror surface of the take-up roll is an important inspection in the production and processing of the web.
[0003]
Conventionally, the measurement of the unevenness of the mirror surface of the take-up roll has been carried out manually by a measurer using visual observation or by using an object difference. That is, the winding roll formed in the winder process is moved to a measuring stand or the like, and the inspection is performed by measuring the distance between the reference surface arranged in a direction substantially parallel to the mirror surface and the mirror surface.
[0004]
[Problems to be solved by the invention]
However, in the manual inspection, the measurement accuracy varies depending on the measurer, and skill is required for quick measurement, so the following problems arise. For example, in the papermaking process, the winding speed in the winder process has increased due to the advancement and speeding up of the papermaking machine, and there is no time for measurement. We are inspecting. However, the demand for the quality of the winding roll product tends to become stricter due to the speeding up of the printing press and the complexity of the printing specifications, and the importance of measuring and checking the unevenness of the mirror surface of the winding roll is further increasing. Therefore, it is necessary to inspect the total number of winding rolls.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a winding roll mirror surface unevenness measuring apparatus capable of improving measurement accuracy and measuring the surface roughness of all winding rolls in a short time. .
[0006]
[Means for Solving the Problems]
As technical means for achieving the above object, the unevenness measuring apparatus for mirror surface of a take-up roll according to the present invention is an unevenness measuring apparatus for mirror surface of a take-up roll that measures the unevenness of the mirror surface of the take-up roll in a non-contact manner. A guide means extending at a suitable distance from the mirror surface to be measured and extending in a direction substantially parallel to the mirror surface as a longitudinal direction, and guided and supported by the guide means slidably along the diameter direction of the mirror surface. The distance measuring means guides the distance measuring means to the guide means and scans in a direction substantially parallel to the diameter direction of the take-up roll, and measures the distance to the mirror surface to measure the unevenness of the mirror surface. It is characterized by measuring.
[0007]
For example, in a state where a winding roll to be measured is placed on the gantry of the unevenness measuring device, the mirror surface is positioned substantially parallel to the guide means. Then, by measuring the distance from the distance measuring means to the mirror surface while sliding the distance measuring means with respect to the guide means, it is possible to measure the change in the unevenness along an arbitrary straight line of the mirror surface. In addition, if the center of a mirror surface is included in the measurement range of the distance measuring means, it is possible to measure a change in unevenness along the diameter of the mirror surface. Also, if the height position of the guide means can be changed, the height position is changed with respect to the diameter of the winding roll to be measured, thereby changing the height of the mirror surface of the winding roll. It is possible to measure the change in unevenness.
[0008]
And in the unevenness measuring device for the winding roll mirror surface that measures the unevenness of the mirror surface of the winding roll in a non-contact manner so that the distance measuring position (height) of the distance measuring means can be easily changed, the mirror surface to be measured A guide means extending at an appropriate distance from the mirror surface in a direction substantially parallel to the mirror surface, and a distance measuring means guided and supported by the guide means slidably along the diameter direction of the mirror surface, It comprises a guide part moving means for moving the guide means in a direction crossing the sliding direction of the distance measuring means. The guide means is moved to an appropriate position, and the distance measuring means is guided to the guide means at the position. The unevenness at an arbitrary position of the winding roll of an arbitrary diameter is measured by measuring the distance to the mirror surface while scanning in a direction substantially parallel to the diameter direction of the winding roll. .
[0009]
That is, when the guide unit is moved by the guide unit moving unit, the portion to be scanned by the distance measuring unit is changed. For this reason, if the guide means is moved in accordance with the diameter of the winding roll to be measured, it is possible to measure the unevenness change in a range including the center of the mirror surface, for example, regardless of the diameter of the winding roll.
[0010]
In addition, the take-up roll being conveyed in the axial direction of the take-up roll in order to measure the unevenness of the mirror surface of the take-up roll being conveyed in any process during shipment from the winder process as a product. In the unevenness measuring apparatus of the take-up roll mirror surface for measuring the unevenness of the mirror surface in a non-contact manner, a guide means extending with a direction substantially parallel to the mirror surface as a longitudinal direction at an appropriate distance from the mirror surface to be measured, Ranging means guided and supported by the guide means slidably along the diameter direction of the mirror surface, and the direction of the guide means intersecting the sliding direction of the distance measuring means, the guide means being It consists of a guide part moving means that removably moves from the take-up roll conveyance area, stops the take-up roll in the middle of conveyance at a predetermined position, moves the guide means to an appropriate position, and measures the measurement at the position. Distance By measuring the distance to the mirror surface while scanning in the direction substantially parallel to the diameter direction of the take-up roll by guiding the guide means, the irregularities at any position of the take-up roll of any diameter are measured. It is characterized by doing.
[0011]
Since the take-up roll is conveyed in the axial direction, it is conveyed with its mirror surface facing forward. When the distance measuring means is in a position where distance measurement can be performed, the guide means and the distance measuring means become obstacles to conveyance. For this reason, when the take-up roll is transported, the guide means and the distance measuring means must be retracted from the transport area, and the guide means supporting the distance measuring means is raised. When the winding roll to be measured is conveyed to the unevenness measuring apparatus, the conveying apparatus is stopped at a predetermined position, and the guide means is lowered by the guide portion moving means so that the distance measuring means faces the predetermined position on the mirror surface. Lower to the position where Then, if the distance measuring means is moved in the diameter direction of the mirror surface while being guided by the guide means, and the distance to the mirror surface is sequentially measured, the unevenness of the mirror surface can be measured.
[0012]
Further, the distance measuring means is slidably and rotatably supported by the guide means so that the unevenness of the mirror surface on both sides of the winding roll conveyed in the axial direction can be measured. By measuring the unevenness of the front mirror surface and the rear mirror surface of the take-up roll conveyed in the axial direction of the take-up roll by rotating the distance means and changing the distance measuring direction, Yes.
[0013]
As described above, when the conveyance device is stopped and the unevenness of the mirror surface on the front side is measured, the distance measuring means is retracted from the conveyance area of the winding roll by a method according to the winding diameter, and the winding roll is conveyed. . If the rear mirror surface passes below the distance measuring means, the conveying device is stopped, and if necessary, the distance measuring means is lowered and the distance measuring means is rotated to move the distance measuring section to the rear side. Opposite the mirror surface. If the distance to the rear mirror surface is measured while the distance measuring means is guided by the guide means and moved, the unevenness of the mirror surface can be measured.
[0014]
Further, in the unevenness measuring device for the mirror surface of the take-up roll that measures the unevenness of the mirror surface on both sides of the take-up roll being conveyed in a direction orthogonal to the axial direction of the take-up roll, each mirror surface to be measured Guide means extending at an appropriate distance from each other and extending substantially parallel to the mirror surface as a longitudinal direction, and distance measuring means guided and supported by the respective guide means slidably along the diameter direction of the mirror surface; The guide means moving means for moving each of the guide means in a direction intersecting the sliding direction of the distance measuring means, stopping the winding roll in the middle of conveyance at a predetermined position, and appropriately positioning the guide means By measuring the distance to the mirror surface while scanning in the direction substantially parallel to the diameter direction of the winding roll by guiding the distance measuring means to the guide means at the position. It is characterized by measuring the unevenness at an arbitrary position of the take-up roll diameter.
[0015]
That is, when the take-up roll is transported in a direction orthogonal to the axial direction, each mirror surface is parallel to the transport direction. Therefore, when the take-up roll is transported to the position of the unevenness measuring device, the transport device is stopped to stop the take-up roll, and the distance measuring means arranged for each mirror surface is guided to the respective guide means. If the distance to each mirror surface is measured while being moved, the unevenness of the mirror surface of each take-up roll being conveyed can be measured almost simultaneously.
[0016]
Further, in the unevenness measuring device for the mirror surface of the take-up roll that measures the unevenness of the mirror surface on both sides of the take-up roll being conveyed in a direction orthogonal to the axial direction of the take-up roll, each mirror surface to be measured Each of the distance measuring means disposed at a position appropriately spaced from the distance measuring means, and a distance measuring unit moving means for moving the distance measuring means up and down. And measuring the distance to the mirror surface while conveying the take-up roll, thereby measuring irregularities at any position of the take-up roll having an arbitrary diameter.
[0017]
When measuring the unevenness of the mirror surface, the distance measuring means is scanned in a direction parallel to the mirror surface. However, when the take-up roll is transported in a direction orthogonal to the axial direction, the same result as that obtained when the distance measuring means at a fixed position is scanned by the transport is obtained. That is, if the distance to the mirror surface is measured by the distance measuring means at a fixed position on the mirror surface of the take-up roll being conveyed, the unevenness of the mirror surface is measured.
[0018]
Further, the distance measuring means can be moved in a direction intersecting with the mirror surface to be measured, and the distance measuring means is moved to a predetermined position according to the width of the take-up roll, and the unevenness of the mirror surface of the take-up roll of any width It is characterized by measuring.
[0019]
When the take-up roll is conveyed in a direction perpendicular to the axial direction, depending on the width of the take-up roll, the distance from the distance measuring means to the mirror surface becomes large, and the distance to the mirror surface is accurately measured by the distance measuring means. You might not be able to do it. For this reason, by moving the distance measuring means in a direction crossing the mirror surface of the take-up roll, the distance measuring means can be positioned at a position where the distance to the mirror surface can be reliably measured. Therefore, the unevenness | corrugation of the mirror surface of the winding roll from which width | variety differs can be measured.
[0020]
Moreover, it is characterized by including preliminary measuring means for measuring in advance the approximate diameter of a winding roll having a mirror surface to be measured.
[0021]
If the position of the mirror surface where the unevenness is to be measured differs depending on the winding roll, the unevenness data to be used for quality control will vary, so the position (height) to be scanned for measurement is constant. For example, it is desirable to scan so as to pass through the center of the mirror surface. In order to position the distance measuring means at a height at which the center of the mirror surface is scanned, the diameter of the winding roll is measured and the height of the distance measuring means is changed accordingly. That is, the diameter of the take-up roll is measured in advance by the preliminary measuring means, and the distance to be scanned is changed according to the measured value.
[0022]
When the take-up roll to be measured is placed on a gantry or a support plate of a transport device, if the direction of the axis is in a predetermined direction, the distance measuring means can scan in a direction parallel to the mirror surface. When the direction of the axis is inclined with respect to a predetermined direction, the distance measuring means cannot be scanned in a direction parallel to the mirror surface, so that an accurate change in unevenness cannot be measured. For this reason, a correction calculation means for correcting based on a deviation of the distance between the straight line along the scanning direction of the distance measuring means and the mirror surface to be measured is provided, and the unevenness data of the mirror surface obtained by the distance measuring means is corrected. It is characterized by measuring the unevenness of the mirror surface.
[0023]
The reference value for correction is calculated by, for example, calculating the inclination in the axial direction of the take-up roll placed on a gantry or the like, and obtaining the reference value from that value, or winding on the straight line scanned by the placed take-up roll. For example, the average value of the distance to the end of the roll is taken as the reference value.
[0024]
Furthermore, the mirror surface unevenness data is compared with a preset threshold value so that the mirror surface unevenness data is not within the predetermined range and can be immediately identified as a winding roll that is not suitable for shipping as a product. And a warning means for outputting a message to the effect when the unevenness data exceeds a threshold value and notifying by a warning lamp or warning.
[0025]
The winding roll determined to be inappropriate is rewound again by the rewinder device to obtain a product.

Note that the leg portion 32 is not shown in the drawings behind the leg portion 31 in FIGS. 2 and 3.
[0028]
On the back side of the leg portions 33 and 34 positioned on the front side in the transport direction of the take-up roll 1, there is provided an elevating guide 4 that supports the respective end portions of the scanning device 5 as guide means so as to be raised and lowered. .

It is connected to the lifting device 7 as means. That is, the scanning device 5 is moved up and down by being guided by the lifting guide 4 through the hanging rod 6 by the operation of the lifting device 7.
[0029]
As shown in FIG. 1, the scanning device 5 is arranged with a direction parallel to the mirror surface 1 b of the take-up roll 1 as a longitudinal direction, and a support bracket 8 is attached to the scanning device 5 in the longitudinal direction of the scanning device 5. That is, it is guided in the diameter direction of the mirror surface 1b and is slidably supported. A distance measuring device 9 as a distance measuring means for measuring the distance to the mirror surface 1b is rotatable at the tip of the support bracket 8 within a range of at least 180 ° about the longitudinal direction of the support bracket 8. It is attached to a rotary table 10 provided.
[0030]
As shown in FIGS. 2 and 3, roll front end detection means 11 for detecting the front end portion of the take-up roll 1 is provided on the front side surface of the leg 31 located on the rear side in the transport direction of the take-up roll 1. Is provided. The transport device 2 is stopped by a signal detected by the roll front end detection means 11 at the front end of the take-up roll 1 being transported, and the mirror surface 1b on the front side of the take-up roll 1 and the distance measuring device 9 at the stopped position. The distance in the direction of the axis 1a is sufficiently included in the distance measuring range of the distance measuring device 9. On the other hand, a roll rear end detecting means 12 for detecting the rear end portion of the take-up roll 1 is provided on the back side of the leg 33 located on the front side in the transport direction of the take-up roll 1. The conveying device 2 is stopped by a signal detected by the trailing end of the winding roll 1 being conveyed by the roll trailing end detecting means 12, and the distance between the mirror surface 1b on the rear side of the winding roll 1 and the distance measurement at the stopped position. The distance of the device 9 in the direction of the axis 1a is sufficiently included in the distance measuring range of the distance measuring device 9.
[0031]
Further, a roll diameter measuring means 13 as a preliminary measuring means is supported on the beam portion 35 of the support frame 3 by a bracket 13a projecting rearward in the conveying direction of the take-up roll 1. This roll diameter measuring means 13 measures the distance to the take-up roll 1 that passes below. From the distance at which the roll diameter measuring means 13 is installed and the distance to the take-up roll 1, The outer diameter of the winding roll 1 is measured.
[0032]
The operation of the embodiment shown in FIGS. 1 to 3 of the apparatus for measuring the unevenness of the mirror surface of the take-up roll according to the present invention constructed as described above will be described below.
[0033]
The winding roll 1 formed in the winder process is fed to the next process by the transport device 2. When attempting to pass through the unevenness measuring apparatus in the middle of the conveying path, the front edge of the winding roll 1 is detected by the roll front end detecting means 11 as shown in FIG. For this reason, the conveyance apparatus 2 stops and the winding roll 1 stops in the said position. The roll diameter measuring means 13 measures the distance to the upper end of the take-up roll 1 and measures the approximate outer diameter of the take-up roll 1. Based on the outer diameter data of the take-up roll 1, the elevating device 7 is operated so that the distance measuring device 9 is positioned at the center height of the take-up roll 1, and both ends thereof are moved to the elevating guide 4. The scanning device 5 is raised and lowered while being guided. Then, the distance measuring unit 9 is made to face the mirror surface 1b on the front side of the take-up roll 1, and the distance to the mirror surface 1b is measured by the scanning device 5 while scanning the distance measuring device 9 in parallel with the mirror surface 1b. For example, the unevenness of the front mirror surface 1b can be measured.
[0034]
When the measurement of the mirror surface 1b on the front side of the take-up roll 1 is completed, the lifting device 7 or the scanning device 5 is operated according to the take-up diameter, and the scanning device 5 and the distance measuring device 9 are transported in the transport area of the take-up roll 1. After being retracted, the transport device 2 is operated to transport the take-up roll 1 again. As shown in FIG. 3, when the trailing edge of the conveyed winding roll 1 is detected by the roll trailing edge detecting means 12, the conveying device 2 stops and the winding roll 1 stops at the position. Since the outer diameter of the winding roll 1 has already been measured by the roll diameter measuring means 13, the lifting device 7 operates to lower the distance measuring device 9 to the height of the center of the winding roll 1 when necessary. At this time, the winding roll having a radius smaller than that of the support bracket 8 does not need to be moved up and down. Then, the rotary table 10 is operated to rotate the distance measuring device 9 by approximately 180 ° so that the distance measuring portion faces the mirror surface 1 b on the rear side of the take-up roll 1. Next, if the distance to the mirror surface 1b is measured while the scanning device 5 scans the distance measuring device 9 parallel to the mirror surface 1b, the unevenness of the rear mirror surface 1b can be measured.
[0035]
If the winding roll 1 is in a predetermined direction with respect to the conveying direction of the conveying device 2, the scanning direction of the distance measuring device 9 is parallel to the mirror surface 1 b of the winding roll 1, and the distance measuring device 9 The acquired unevenness data is reliable. However, if the axial direction of the take-up roll 1 does not match the transport direction, the scanning direction of the distance measuring device 9 is not parallel to the mirror surface 1b, and the acquired unevenness data cannot be trusted. Therefore, it is necessary to correct the distance measurement data up to the mirror surface 1b to obtain reliable unevenness data. Therefore, the unevenness data is obtained by correcting the acquired distance measurement data up to the mirror surface 1b through a correction calculation means (not shown). For example, when the distance measuring device 9 measures the distance to the mirror surface 1b, the correction calculation means determines an average value of the distances to both ends of the mirror surface 1b as a reference value for correction, and the reference value and the measurement value are measured. The unevenness data is obtained by correcting the distance measurement data according to the deviation from the distance data.
[0036]
Further, in order to determine whether or not the unevenness of the mirror surface 1b of the take-up roll 1 is within a range allowed for the take-up roll 1, comparison means for comparing the obtained unevenness data with a preset threshold value ( (Not shown). And when the uneven | corrugated data remove | deviate from the range of this threshold value, a warning means (not shown) is provided so that a warning lamp may be turned on or a warning may be issued to notify that fact.
[0037]
The unevenness measuring apparatus according to the embodiment shown in FIG. 4 shows an unevenness measuring apparatus for a mirror surface of a take-up roll when the take-up roll 1 is conveyed in a direction orthogonal to its axis, that is, a direction penetrating the paper surface. A pair of support frames 3 are provided across the transport device 2, and lift guides 4 are provided on the legs 36 and 37 on the transport device 2 side of the pair of support frames 3. Note that the leg portion 37 does not appear on the drawing behind the leg portion 36 in FIG. Both ends of a scanning device 5 as guide means are supported by the lift guide 4 so as to be movable up and down. Further, the scanning device 5 is suspended from the tip of the suspension rod 6, and this suspension rod 6 is connected to an elevating device 7 as a guide unit moving means disposed on the beam portion 38 of the support frame 3. Yes. That is, the scanning device 5 is moved up and down by being guided by the lifting guide through the hanging rod 6 by the operation of the lifting device 7.
[0038]
The scanning device 5 is disposed with a longitudinal direction in a direction parallel to the left and right mirror surfaces 1c and 1d of the take-up roll 1, and a support bracket 8 is attached to the scanning device 5 in the longitudinal direction, that is, a mirror surface. Guided in the diameter direction of 1c and 1d, it is slidably supported. A distance measuring device 9 as a distance measuring means for measuring the distance to the mirror surfaces 1c and 1d is supported at the tip of the support bracket 8.
[0039]
Further, a roll detection means (not shown) similar to the roll front end detection means 11 of the embodiment shown in FIG. 1 is detected at an appropriate position of the support frame 3 to detect that the take-up roll 1 to be conveyed passes. When the roll detecting means detects the winding roll 1, the conveying device 2 is stopped by the signal.
[0040]
In the unevenness measuring apparatus according to the embodiment shown in FIG. 4, when the winding roll 1 is transported to the unevenness measuring apparatus by the transporting device 2, the transporting apparatus 2 is detected by a signal detected by a roll detection unit (not shown). Stops. When the scanning device 5 scans the distance measuring device 5 through the support bracket 8 along the respective mirror surfaces 1c and 1d and measures the distances to the respective mirror surfaces 1c and 1d, the respective mirror surfaces 1c are measured. , 1d unevenness data can be acquired simultaneously.
[0041]
In the unevenness measuring apparatus according to the embodiment shown in FIG. 4, since the scanning device 5 and the distance measuring device 9 are disposed outside the conveyance area of the winding roll 1, the conveyance roll does not become an obstacle to conveyance. It is not necessary to raise and lower these scanning device 5 and distance measuring device 9 in order to allow conveyance of 1. Further, similarly to the unevenness measuring apparatus according to the embodiment shown in FIG. 1, roll diameter measuring means for measuring the outer diameter of the take-up roll 1 in advance is provided, and the distance measuring device 9 is set to the mirror surface 1c based on the measurement data. It can also be moved up and down to an appropriate position for measuring the unevenness of 1d.
[0042]
The unevenness measuring apparatus according to the embodiment shown in FIG. 5 measures the unevenness of the mirror surfaces 1c and 1d when the take-up roll 1 is conveyed in a direction orthogonal to the direction of the axis, as in the embodiment shown in FIG. Although the uneven | corrugated measuring apparatus of the mirror surface of the winding roll to show is shown, in embodiment shown in this FIG. 5, it can measure about the winding roll 1 of various width | variety. In other words, the support bracket 8 that supports the distance measuring device 9 has the base end portion supported by the scanning device 5 and the distance measuring position adjusting means 14 having the distal end portion extended in the axial direction of the take-up roll 1. 1 is slidably supported in the axial direction. The sliding of the support bracket 8 with respect to the distance measuring position adjusting means 14 is performed by the power of a motor (not shown) or the like, and the support bracket 8 with respect to the distance measuring position adjusting means 14 according to the width of the take-up roll 1. The position is adjusted.
[0043]
In the unevenness measuring apparatus according to the embodiment shown in FIG. 5, the position of the support bracket 8 with respect to the distance measuring position adjusting means 14 is adjusted in advance according to the width of the winding roll 1 formed in the winder process. About the conveyed winding roll 1, the unevenness | corrugation of the mirror surfaces 1c and 1d is measured similarly to the unevenness | corrugation measuring apparatus of embodiment shown in FIG.
[0044]

It is also possible to set the distance device 9 to a fixed position, and sequentially change the distance measurement position by the distance measurement device 9 by the conveyance travel of the winding roll 1. In the case of this structure, the scanning device 5 is unnecessary and the structure can be simplified.
[0045]
Further, in the unevenness measuring apparatus according to the embodiment shown in FIGS. 4 and 5, the mirror surfaces 1c and 1d and the scanning direction of the distance measuring device 9 are not parallel to each other as in the case of the embodiment shown in FIG. It is also possible to provide a correction operation means for correcting the distance measurement data acquired in step 1 and a warning means for issuing a warning by comparing the unevenness data with a threshold value.
[0046]
In the unevenness measuring apparatus according to the embodiment described above, the structure for measuring the unevenness of the mirror surfaces 1b, 1c, 1d is shown while the winding roll 1 is being transported by the transport device 2, but the measurement is performed during the transport.
