Description

Technical Field

[0001] This disclosure relates to the field of thickness measurement technology for production lines, and in particular to a real-time thickness measurement device and system for asphalt waterproof membrane production lines. Background Technology

[0002] In related technologies, asphalt waterproof membrane production lines produce at a speed of 0.5-1 meter per second. Since it is difficult to manually measure the membrane while it is in motion, the thickness is manually measured only when the membrane is packaged and cut into a whole roll. This manual measurement method is not only time-consuming and labor-intensive, but also cannot detect in time when the thickness does not meet the standard.

[0003] Currently, most related technologies use one or more laser sensors fixed in position. The laser point of the sensor directly measures and takes values ​​from the surface of the roll material. However, some roll materials have irregular embossing such as stripes and squares on their surface. This causes the laser point to sometimes measure the surface of the roll material, sometimes the bottom of the embossing, and sometimes the middle of the embossing. The value that truly reflects the thickness of the waterproof roll material is the thickness at the top high point. This leads to inaccurate thickness measurement of waterproof roll materials with embossing in related technologies. Utility Model Content

[0004] In view of this, the present disclosure provides a thickness measuring device for a production line, wherein the surface of a waterproof membrane has an embossed pattern, comprising: a support and a measuring component. The measuring component is disposed on the support and includes a first mounting bracket, a measuring foot, and a sensor. One end of the first mounting bracket is rotatably connected to the support, and the other end extends toward the waterproof membrane, with the upper part of the other end of the first mounting bracket forming a reference surface extending along a first direction. The measuring foot is pivotally disposed at the other end of the first mounting bracket, located below the reference surface, and rolls against the upper surface of the waterproof membrane. The length of the measuring foot along a second direction is greater than the length of the embossing along the second direction, and the second direction is orthogonal to the first direction. The sensor is disposed above the reference surface to measure the distance between the sensor and the reference surface.

[0005] Therefore, the measuring foot rolls against the upper surface of the waterproof membrane. As the waterproof membrane moves, it causes the measuring foot and the first mounting bracket of the measuring component to rotate around the support. This change in the thickness of the waterproof membrane causes a change in the position of the measuring foot and the first mounting bracket, which in turn causes a change in the position of the reference surface, and consequently a change in the distance between the sensor and the reference surface. Based on this change in distance, the change in the thickness of the waterproof membrane can be calculated, and thus the thickness of the waterproof membrane can be measured. Since the length of the measuring foot along the second direction is greater than the length of the embossing along the second direction, the measuring foot always remains against the upper surface of the waterproof membrane and does not enter the recessed parts of the embossing. This allows for continuous measurement of the waterproof membrane thickness, avoiding interference from the embossing. Attached Figure Description

[0016] Figure 1 The schematic diagram illustrates the principle of a thickness measuring device for a waterproof membrane production line.

[0017] Based on the problems existing in related technologies, this disclosure provides a thickness measuring device for a production line. The waterproof membrane 3 has an embossed surface and includes a support 1 and a measuring component 2. The measuring component 2 is disposed on the support 1 and includes a first mounting frame 21, a measuring foot 22, and a sensor 23. One end of the first mounting frame 21 is rotatably connected to the support 1, and the other end extends towards the waterproof membrane 3. The upper part of the other end of the first mounting frame 21 forms a reference surface 211 extending along a first direction. The measuring foot 22 is pivotally disposed at the other end of the first mounting frame 21. The measuring foot 22 is located below the reference surface 211 and rolls against the upper surface of the waterproof membrane 3. The length of the measuring foot 22 along a second direction is greater than the length of the embossing along the second direction, and the second direction is orthogonal to the first direction. The sensor 23 is disposed above the reference surface 211 to measure the distance between the sensor 23 and the reference surface 211.

[0018] In this embodiment, the measuring foot 22 rolls against the upper surface of the waterproof membrane 3. As the waterproof membrane 3 moves, it causes the measuring foot 22 and the first mounting bracket 21 of the measuring assembly 2 to rotate around the support 1. This change in the thickness of the waterproof membrane 3 causes a change in the position of the measuring foot 22 and the first mounting bracket 21, which in turn causes a change in the position of the reference surface 211, and consequently a change in the distance between the sensor 23 and the reference surface 211. Based on this change in distance, the change in the thickness of the waterproof membrane 3 can be calculated, and thus the thickness of the waterproof membrane 3 can be measured. Since the length of the measuring foot 22 along the second direction is greater than the length of the embossing along the second direction, the measuring foot 22 always remains against the upper surface of the waterproof membrane 3 and does not enter the recessed portion of the embossing. Therefore, the thickness of the waterproof membrane 3 can be measured continuously, avoiding interference from the embossing on the thickness measurement.

[0019] In some illustrative embodiments of this disclosure, the first direction is the length direction of the waterproof membrane 3 (e.g., Figure 1(As shown in X) is also the direction in which the waterproof membrane 3 moves on the production line of the waterproof membrane 3. The second direction is the width direction of the waterproof membrane 3. It can be understood that the first and second directions are usually orthogonal and horizontal. Furthermore, the third direction is orthogonal to the first and second directions, and at this time the third direction is the vertical direction.

[0020] In some illustrative embodiments of this disclosure, the length of the measuring foot 22 in the second direction is adapted to the length of the embossing in the second direction, as long as the length of the measuring foot 22 in the second direction is greater than the length of the embossing in the second direction. For example, the length of the measuring foot in the second direction is 10 mm, and the length of the embossing in the second direction is less than 10 mm.

[0021] As an example, sensor 23 can be an optical sensor such as an infrared sensor or a laser sensor. The waterproof membrane 3 can be an asphalt waterproof membrane, or it can be a common waterproof material such as polyvinyl chloride or thermoplastic polyolefin.

[0022] In some illustrative embodiments of this disclosure, because the reference surface 211, as part of the first mounting frame 21, rotates around the bracket 1 with the first mounting frame 21, the positional change of the reference surface 211 is not strictly vertical. However, the center of rotation and the position of the waterproof membrane 3 are fixed. Therefore, although the height change caused by the positional change of the reference surface 211 and the thickness change of the waterproof membrane 3 are not strictly equal, they have a definite relationship, and the thickness change can be calculated based on their relative positions. The height change caused by the positional change of the reference surface 211 and the thickness change of the waterproof membrane 3 can be understood as a first error. The closer the direction of the first mounting frame 21 is to horizontal, the larger the radius of rotation, and the smaller the thickness change, the closer the data change measured by the sensor 23 is to the thickness change of the waterproof membrane 3. If the first error is within an acceptable range, the change data of the sensor 23 can be approximately considered as the thickness change data of the waterproof membrane 3.

[0023] In some illustrative embodiments of this disclosure, the data from sensor 23 can be output to an external host computer, where an error compensation program can be set to compensate for the first error. The error compensation program is based on the geometric parameters and motion relationship of the thickness measuring device. It is understood that the specific calculation method is a direct application of existing error compensation technology, and this disclosure does not propose any improvement to the specific calculation method, nor is the error compensation program the core of this disclosure.

[0024] As an example, the error compensation program employs a geometric modeling compensation method: a thickness calculation model is established based on the geometric parameters of the thickness measuring device. These geometric parameters include the distance from the center of the measuring foot to the rotation center of the first mounting bracket, the relative coordinates of the reference roller axis and the measuring foot axis in the plane formed by the second and third directions, and the sensor's installation position relative to the rotation center. The program calculates the actual thickness of the waterproof membrane based on real-time sensor readings and the geometric model. In addition, other commonly used calculation methods can be used, as long as error compensation is achieved.

[0025] According to embodiments of this disclosure, a reference roller 4 is further included, pivotally disposed below the measuring foot 22 and rollingly abutting against the lower end face of the waterproof membrane 3. The waterproof membrane 3 passes between the measuring foot 22 and the reference roller in a first direction.

[0026] In this implementation, the reference roller can support the waterproof membrane 3, and in turn support the measuring foot 22, thus preventing the waterproof membrane 3 from deforming due to its own weight and the pressure of the measuring foot 22, which would otherwise cause measurement errors.

[0027] In some illustrative embodiments of this disclosure, the waterproof membrane moves at a speed of 0.5 meters per second to 1 meter per second.

[0028] In some illustrative embodiments of this disclosure, friction is introduced at the contact point between the measuring foot 22 and the waterproof membrane 3, which hinders the movement of the waterproof membrane 3. Therefore, the reference roller 4 can also be configured to actively rotate to provide power for the movement of the waterproof membrane 3.

[0029] In some illustrative embodiments of this disclosure, the reference roller 4 is located below the measuring foot 22, but this is not limited to the reference roller 4 being directly below the measuring foot 22. When the reference roller 4 is located below the measuring foot 22 in any other way than directly below it, the waterproof membrane 3 will undergo slight deformation, but the measuring foot 22 will still abut against the waterproof membrane 3, and the waterproof membrane 3 will abut against the reference roller 4, that is, the reference roller 4 and the waterproof membrane 3 will be tangent. At this time, the change in height of the measuring foot 22 is not equal to the change in thickness of the waterproof membrane 3, but is a definite relationship related to the relative position of the axes of the measuring foot 22 and the reference roller 4. The thickness change can be calculated based on the relative position relationship. At this time, the difference between the numerical value of the change in height of the measuring foot 22 and the change in thickness of the waterproof membrane 3 can be understood as a second error.

[0030] Understandably, when the reference roller 4 is located directly below the measuring foot 22, the closer the line connecting their axes is to vertical, the smaller the second error will be. If the second error is within an acceptable range, the change data of the sensor 23 can be approximated as the thickness change data of the waterproof membrane 3.

[0031] In some illustrative embodiments of this disclosure, the data from sensor 23 can be output to an external host computer, where an error compensation program can be set to compensate for a second error. The compensation for the second error is based on the first error.

[0032] It is understandable that when the reference roller 4 is located directly below the measuring foot 22, the line connecting their axes is perpendicular to the horizontal plane. At this time, the axes of the reference roller 4, the waterproof membrane 3, and the measuring foot 22 are on a straight line and the line connecting them is vertical. At this time, the second error is zero.

[0033] According to an embodiment of this disclosure, the measuring foot 22 is configured as an annular shape and rotates about a pivot 212 disposed at the other end of the first mounting bracket 21. In this embodiment, the annular measuring foot 22 can rotate about the pivot 212, thereby rotating as the waterproof membrane 3 moves. At this time, the friction between the measuring foot 22 and the waterproof membrane 3 is rolling friction, thereby improving the durability of the measuring foot 22.

[0034] In some illustrative embodiments of this disclosure, the measuring foot is selected from bearings, which are made of ceramic bearings or ordinary steel bearings. Preferably, ceramic bearings are selected from the measuring foot to obtain better wear resistance and high temperature resistance.

[0035] According to an embodiment of this disclosure, the bracket 1 includes a mounting base 11, a first branch 12, and a second branch 13. The mounting base 11 is suspended from an external mounting foundation. The first branch 12 is disposed on one side of the mounting base 11, and the measuring component 2 is configured to be slidably disposed on the first branch 12 along a second direction. The second branch 13 is disposed on the other side of the mounting base 11, and the sensor 23 is slidably disposed on the second branch 13 along the second direction. The first mounting bracket 21 and the sensor 23 are configured to slide synchronously relative to the bracket 1 along the second direction to measure the thickness of the waterproof membrane 3 at different locations.

[0036] In this embodiment, the first mounting bracket 21 can slide along the second direction on the first support 12, and the sensor 23 can slide along the second direction on the first support 12, while the first support 12 and the second support 13 are both disposed on the mounting base plate 11. Thus, the first mounting bracket 21 and the sensor 23 can slide synchronously in the second direction, and the user can slide them synchronously to the desired measurement position, thereby realizing the measurement of various positions in the width direction (i.e., the second direction) of the waterproof roll 3.

[0037] Furthermore, during measurement, the position of the reference surface 211 changes with the movement and thickness of the waterproof membrane 3, while the position of the sensor 23 should not change with the movement and thickness of the waterproof membrane 3. At the same time, the sensor 23 is set above the reference surface 211, and the two are in the same position in the second direction. If the two are set on the same branch of the bracket 1, they are prone to mutual interference in actual use. Setting them on different branches can avoid interference and thus avoid unnecessary errors.

[0038] Furthermore, although the sensor 23 and the reference surface 211 are disposed on different branches of the bracket 1, the first branch 12 and the second branch 13 share the same mounting base, namely the mounting substrate 11. Therefore, their relative positions can be determined based on their positions relative to the mounting substrate 11, facilitating the measurement and calculation of thickness.

[0039] In some illustrative embodiments of this disclosure, the mounting base 11 is suspended from an external mounting foundation. The mounting foundation can be the production line frame of the waterproof membrane 3 production line or the ground on which the production line is placed, as long as the mounting foundation does not change with the movement of the waterproof membrane 3. It is understood that the reference roller 4 can also be mounted on the mounting foundation, so that the thickness measuring device of the entire waterproof membrane 3 production line has a common mounting foundation.

[0040] According to an embodiment of this disclosure, the widths of the first branch 12, the second branch 13, and the reference roller 4 along the second direction are configured to be greater than the width of the waterproof membrane 3 along the second direction, so that the first mounting bracket 21 and the sensor 23 can be moved to the outside of the waterproof membrane 3.

[0041] In this implementation, the first mounting bracket 21 and the sensor 23 can be moved to the outer side of the waterproof membrane 3 in the second direction. At this time, the measuring foot 22 directly abuts against the reference roller 4, and the sensor 23 data when there is no waterproof membrane 3 can be measured. This data can then be used as a reference to measure the thickness of the waterproof membrane 3. It is understood that the measurement system can be zeroed at this time, and then the first mounting bracket 21 and the sensor 23 can be moved onto the waterproof membrane 3 to measure the thickness.

[0042] In some illustrative embodiments of this disclosure, the first branch 12, the second branch 13, and the reference roller 4 are positioned opposite each other and have equal widths along the second direction, thereby the sensor 23 and the reference surface 211 have the same movable stroke in the second direction. It is understood that the overlapping portion of the first branch 12, the second branch 13, and the waterproof membrane 3 in the second direction is accessible to both the sensor 23 and the reference surface 211, i.e., the portion where thickness measurement can be performed. The overlapping portion of the first branch 12, the second branch 13, and the reference roller 4 in the second direction, where no waterproof membrane 3 is present, allows for reference measurement. The positions of the first branch 12, the second branch 13, the waterproof membrane 3, and the reference roller 4 in the second direction can be flexibly set to meet the requirements of reference measurement and thickness measurement.

[0043] Preferably, the first branch 12, the second branch 13, the waterproof membrane 3, and the reference roller 4 are aligned in the center in the second direction, that is, all four are arranged opposite each other and have a common centerline in the plane formed by the second and third directions.

[0044] According to an embodiment of the present disclosure, one of the first branch 12 and the first mounting bracket 21 forms a shaft structure, and the other forms a cylindrical structure sleeved outside the shaft structure.

[0045] In this embodiment, the first mounting frame 21 and the first support 12 rotate relative to each other through the cooperation of the shaft and cylinder. Thus, the movement of the waterproof membrane can drive the first mounting frame 21 to rotate around the first support 12 through the measuring foot 22, thereby driving the reference surface 211 to move. The thickness of the waterproof membrane 3 is indirectly measured by measuring the distance between the reference surface 211 and the sensor 23.

[0046] In some illustrative embodiments of this disclosure, the cylindrical structure of the first support 12 has a groove extending in a second direction, and the first mounting bracket 21 extends out of the groove. The groove extending in the second direction facilitates the relative sliding of the first mounting bracket 21 relative to the first support 12 and allows the first mounting bracket 21 to rotate relative to the first support 12.

[0047] According to an embodiment of this disclosure, the second branch 13 includes a slide rail 131 and a second mounting bracket 132, and the sensor 23 is slidably connected to the slide rail 131 via the second mounting bracket 132.

[0048] According to an embodiment of this disclosure, the second mounting bracket 132 includes a slider 1321, a first mounting portion 1322, and a second mounting portion 1323. The slider 1321 is slidably disposed on a slide rail 131. The first mounting portion 1322 is connected to the slider 1321 and configured to be movable relative to the slider 1321 in a first direction. The second mounting portion 1323 is connected to the first mounting portion 1322, moves with the first mounting portion 1322, and is movable in a third direction between a first position near the reference plane 211 and a second position away from the reference plane 211.

[0049] In this implementation, the cooperation between the slider 1321 and the slide rail 131 allows the sensor 23 to move in the second direction; the cooperation between the first mounting part 1322 and the slider 1321 allows the sensor 23 to move in the first direction; and the cooperation between the second mounting part 1323 and the first mounting part 1322 allows the sensor 23 to move in the third direction. This enables the sensor 23 to move in three directions, facilitating adjustment during use and ensuring that the sensor 23 is always aligned with the reference surface 211.

[0050] In some illustrative embodiments of this disclosure, the sensor 23 is fixedly mounted on the second mounting portion 1323. Specifically, the sensor 23 can be mounted on the second mounting portion 1323 via a mounting bracket, or it can be fixed to the second mounting portion 1323 by adhesive or other means. It is understood that the specific mounting method is not limited, as long as reliable installation and fixation can be achieved.

[0051] In some illustrative embodiments of this disclosure, the upper surface of the slider 1321 is provided with at least one threaded hole, and the first mounting part 1322 is a plate-like structure extending along a first direction, and is provided with at least one first sliding groove extending along the first direction. At least one locking fastener passes through the first sliding groove and enters the threaded hole. At this time, the first mounting part 1322 can move along the first direction through the cooperation of the locking fastener and the first sliding groove. Furthermore, the depth of the locking fastener entering the threaded hole can be used to switch between a tight state and a loose state of the first mounting part 1322. When no adjustment is required, the first mounting part 1322 is fixed to the slider 1321 by the locking fastener. It is understood that the number of the first sliding groove, threaded hole and fastener is equal and not limited to one; two or more fasteners can improve positioning accuracy. This can prevent relative sliding between the first mounting part 1322 and the slider 1321 when only one fastener is provided.

[0052] In some illustrative embodiments of this disclosure, the second mounting portion 1323 is a plate-like structure extending along a third direction, and at least one second sliding groove extending along the third direction is provided on the second mounting portion 1323. At least one threaded hole is provided on the end face of the first mounting portion 1322 away from the slider 1321, and at least one locking fastener passes through the second sliding groove and enters the threaded hole. At this time, the second mounting bracket 132 can move along the third direction through the cooperation of the locking fastener and the second sliding groove. Furthermore, the depth to which the locking fastener enters the threaded hole can switch the second mounting bracket 132 between a tight and loose state. It is understood that the number of second sliding grooves, threaded holes, and fasteners is equal and not limited to one; two or more fasteners can improve positioning accuracy. This avoids relative sliding between the second mounting portion 1323 and the first mounting portion 1322 when only one fastener is provided.

[0053] In some illustrative embodiments of this disclosure, the second mounting portion 1323 is a plate-like structure extending along a third direction, and has at least two sets of through holes in the third direction, with the distance between two adjacent sets of through holes being predetermined. The end face of the first mounting portion 1322 away from the slider 1321 has at least one threaded hole, through which a fastener enters the threaded hole. The switching between the tight and loose states is the same as in the slide groove embodiment. In this embodiment, the position adjustment of the sensor 23 in the third direction is discrete and the distance is predictable; therefore, when adjusting the position in the third direction, only data compensation based on the predictable distance is needed, without the need for re-zeroing.

[0054] In some illustrative embodiments of this disclosure, the through holes can be configured in two or more groups with equal spacing, and the number of groups is adapted to the actual measurement requirements. Each group is provided with at least two through holes to prevent relative rotation between the first mounting part 1322 and the second mounting part 1323.

[0055] According to embodiments of this disclosure, at least two measuring components 2 and second branches 13 are provided in a one-to-one correspondence along the second direction, which is suitable for simultaneously measuring the thickness of the waterproof membrane 3 at different locations.

[0056] In this implementation, the measuring component 2 and the second support 13 can move in the second direction to measure the thickness at different locations. Furthermore, by providing multiple components that can simultaneously measure the thickness at multiple different locations, the thickness of the waterproof membrane 3 can be measured at multiple locations simultaneously. The number of measuring components 2 and the second support 13 can be set according to requirements.

[0057] This disclosure also provides a thickness measurement system for a waterproof membrane 3 production line, including any of the aforementioned thickness measurement devices and a host computer. The host computer is configured with an error compensation program and / or a distance compensation program. The error compensation program is used to compensate for the aforementioned first and second errors, and the distance compensation program is used to compensate for the distance when the sensor 23 is adjusted to a known distance position in a third-order direction. It is understood that error compensation and distance compensation can be completed using a single program. After compensation calculation, the host computer can calculate the thickness of the waterproof membrane 3 based on the data measured by the sensor 23.

[0058] In some illustrative embodiments of this disclosure, the host computer has a display panel that can display data measured by the sensor, the thickness value of the waterproof membrane calculated by the program, and the thickness variation curve of the waterproof membrane. The host computer also has a storage module suitable for storing the data measured by the sensor, the thickness value of the waterproof membrane calculated by the program, and the thickness variation curve of the waterproof membrane for easy retrieval.

[0059] The embodiments of this disclosure have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of this disclosure is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of this disclosure, and all such substitutions and modifications should fall within the scope of this disclosure.
