Abstract
Description
[0001] Traversing sensor system
[0002] The invention relates to a traversing measuring system comprising a scanner frame and at least one measuring carriage movably connected to the scanner frame, wherein the measuring system is designed to guide the measuring carriage traversing in the machine transverse direction (CD) over a paper web (12) moving in the machine running direction (MD) and to record measured values,
[0003] Prior art patent DE202012013156 U1 discloses a traversing frame as a measuring frame for use in a machine for producing a fibrous web. Traversing devices that accommodate sensors are guided over the paper web within the frame. These traversing devices are arranged on the top and bottom of the frame. Prior art patent JP200272899 A also discloses a traversing camera system that, while arranged laterally on a frame, does not include a carriage.
[0004] These measuring systems and scanners are used in state-of-the-art technology for quality measurement and control in paper mills. For the production of paper, cardboard, and / or tissue in paper mills, reliable, continuous, and precise measurement of product quality is particularly important to enable efficient production control. Furthermore, a maintenance-friendly measuring system is especially advantageous for ensuring effective production.
[0005] The object of the invention is to provide a traversing measuring system that has a reduced tendency to become contaminated in order to ensure reliable quality measurement and to enable simplified assembly and / or maintenance.
[0006] The problem is solved according to the invention by an embodiment according to the independent claim. Further advantageous embodiments of the present invention are found in the dependent claims.Furthermore, the object of the invention is achieved by a traversing measuring system according to the preamble of the first claim, wherein the measuring carriage is connected to a movable carriage by means of a lateral holding device, wherein the carriage is arranged inside a housing of the scanner frame and is mounted there on a rail device by means of at least one bearing element, wherein the rail device comprises two rails which are arranged vertically one above the other, and wherein the lateral support projects laterally out of the housing from the scanner frame in the machine direction, wherein the bearing element comprises two support rollers and two guide rollers which are movably mounted on the rail device, wherein the support rollers are arranged on the lower rail and the guide rollers are arranged on the upper rail.
[0007] The lateral support device is advantageously designed in a dimensionally stable C-shape. The single-sided opening from the scanner housing reduces the open area within the scanner housing, thus minimizing the ingress of contaminants. As is common in the prior art, the traversing measuring system also features an opening in the scanner frame, protected by a cover strip, for the passage of the lateral support. Unlike conventional scanner frames, this opening is located laterally. Therefore, the closed side of the scanner frame can be positioned to face a potential source of contamination (such as a glue gun). This reduces the risk of contamination of the moving components inside the scanner frame and the cover strip.Furthermore, trials of this invention have shown that mounting the lateral holding device on one vertical side of the scanner frame already reduces contamination. In paper, cardboard, and / or tissue web production plants, fine dusts are generated, which often contain mineral components such as calcium carbonate and / or kaolin. If these dusts enter bearings and / or guide rails, they can lead to deposits and damage. The one-sided holding device is also advantageous because it allows good accessibility for maintenance and / or assembly work on the measuring carriage and scanner frame. For example, side elements of the scanner frame housing can be designed as flaps or removable openings. Supply lines and the drive system can thus be replaced or serviced without having to completely disassemble the measuring carriage.Here, the scanner frame with the side-mounted support device offers a distinct advantage compared to prior art scanner frames with a bottom-running cover strip. With a bottom-running cover strip, the internally mounted components, particularly in the lower profile, are only accessible after removing the scanner. The carriage's placement inside the housing is particularly advantageous, ensuring smooth movement on the rails without interference from dirt. A particularly cost-effective and robust carriage design incorporates two support rollers and two guide rollers. The support rollers effectively transfer the weight of the measuring carriage to the lower rail, while the guide rollers absorb moment and / or alternating loads on the upper rail.The simplified design with only four rollers allows for improved maintenance and reduces complexity compared to state-of-the-art trolleys that use a larger number of wheels or ball bearings to absorb the forces of the measuring device.
[0008] A further advantage is a traversing measuring system, wherein the lateral holding device includes supply and / or communication lines and is connected inside the housing of the scanner frame with a cable carrier.
[0009] The lateral support can advantageously be in the form of a tube, thus enclosing the supply lines. The sensors in the measuring vehicle are supplied with electricity, compressed air, and / or cooling water; the supply lines therefore include corresponding cables and hoses. Furthermore, the supply lines can include a data connection / cable to enable information exchange between sensors, a control device, and / or a higher-level control system, in particular a quality control system. A cable guide is a guide device designed to transfer the supply lines smoothly and without kinks to the movable lateral support device, while the other side of the cable guide is fixed to the scanner frame. A cable guide can advantageously include a guide channel open on one side, made of movably connected support elements.
[0010] A further advantage is a traversing measuring system, wherein the carriage is movably mounted on a rail device by means of two support rollers and two guide rollers, wherein the rail device comprises two rails arranged one above the other, the support rollers arranged on the lower rail and the guide rollers on the upper rail.
[0011] The arrangement of the rails, one above the other, is aligned with the direction of gravity, allowing for an inclination of up to ±45° from the vertical. The lower rail bears the majority of the measuring carriage's weight, while the upper rail primarily serves to counteract horizontal forces. The rail assembly advantageously comprises two rails, as well as the bearings and fasteners required to align these rails and secure them within the scanner frame. The two guide rails are rigidly connected via defined spacers / brackets. This simplifies the alignment of both guide rails. One side is placed "in the water," and the opposing rails are aligned parallel to the first.
[0012] A further advantage is a traversing measuring system, wherein the rail device is arranged in the machine transverse direction (CD) within the housing of the scanner frame, the rail device comprising support elements that support the rails and connect them to the housing of the scanner frame, the support elements preferably being arranged at intervals of 200 mm to 800 mm and comprising an adjustment device. The support elements are advantageously designed as ribs having a C-shape and are configured to hold the upper and lower rails. The support elements also advantageously include connection brackets designed to be detachably connected to the housing. A scanner frame spans a very wide paper web, which typically covers a range of 2 to 12 m in the machine transverse direction CD.To enable precise measurement, particularly with two measuring carriages across the width in the machine's transverse direction CD, compensation for deflection in the direction of gravity G is advantageous. This can be achieved using support elements that include an adjustment device. This allows for compensation of any deflection of the scanner frame and ensures that the rails of the rail system are precisely aligned straight across the entire transverse direction of the machine. The support elements maintain the rails in a horizontal position, independent of any deflection of the scanner frame, and align them in the machine's transverse direction. For installation and adjustment of the measuring carriage positions, a laser measurement system mounted on the scanner frame can be advantageously employed.
[0013] A further advantage is a traversing measuring system in which the gap in the housing, through which the lateral support device protrudes, is sealed with a movable sealing element, in particular with a sealing strip and / or sealing brushes. Additional sealing of the scanner frame housing is advantageous to ensure that no dust penetrates the housing, even through the remaining opening. Sealing with a sealing strip, sealing brushes, and / or sealing lips is advantageous here. This prevents dust from entering the scanner frame housing despite movement of the measuring carriage.
[0014] A further advantage is a traversing measuring system in which the rail device is arranged on a center-of-gravity plane that is both defined by the rail device and essentially passes through the center of gravity of the measuring carriage connected by means of the lateral support. The center-of-gravity plane largely keeps the system in balance, thus advantageously enabling guidance, particularly by two rails in a rail device. The loads from the weight of the measuring carriage are thereby transferred to the rails essentially in the direction of gravity, and precise guidance of the measuring carriage is advantageously enabled. The center-of-gravity plane is advantageously defined by the central axes of the two parallel rails, with the center of gravity of the measuring carriage having a maximum distance of 100 mm from this plane, and particularly advantageously a distance of less than 50 mm.The upper rail of the track system plays a subordinate role, acting as a guide rail that primarily absorbs minor forces resulting from inaccuracies, vibrations, thermal changes, and / or contamination. The center of gravity of the sensors in the measuring system can be considered during the sensor design to enable one-sided mounting. Furthermore, weights can be attached to the measuring carriage to adjust the center of gravity. The center of gravity of the measuring carriage can thus be advantageously positioned below the vertical guide rails, allowing the carriage to hang from the supporting guide rail similarly to a gondola.
[0015] Furthermore, a traversing measuring system is advantageous, wherein the scanner frame comprises a cabinet element in which a control device and / or a communication unit is arranged, wherein the control device is designed to control a drive unit for the movement of the measuring carriage and / or to ensure a media supply to the measuring carriage.
[0016] Scanner frames advantageously and typically comprise two measuring carriages, each arranged one above the other on one side of the paper web. The scanner frame completely encloses the paper web, with the elements connecting the upper and lower crossbeams advantageously designed as cabinet elements. A symmetrical design is particularly advantageous with the single-sided mounting devices used, as this allows for flexible mounting of the traversing measuring system. Depending on the available connection lines and infrastructure, and depending on the orientation of the machine's direction of travel (MD), the drive system (drive side) and the control and supply technology can be housed in the cabinet elements on one side. This allows for mounting in both directions, so that the side support can always be positioned on the side facing away from the direction of travel.In the context of this invention, a structural unit means a housing that is largely closed off from the environment. Advantageously, the housing can also comprise several interconnected individual parts that are assembled as modules. Openings for ventilation, doors, maintenance hatches, and penetrations for supply lines are also provided.
[0017] A further advantage is a traversing measuring system in which a cabinet element is arranged within the scanner frame. This cabinet element comprises a control unit and a communication unit, designed to control the movement of the measuring carriage and to ensure the supply of media to the measuring carriage. The scanner frame advantageously includes a control cabinet housed in the same enclosure, allowing for direct connection of supply lines and enabling control of the measuring carriages across the web width in the machine transverse direction (CD) directly within the scanner frame. Furthermore, the control unit can advantageously aggregate and support the communication of the individual measured values with a higher-level control system. The control unit can also include a data storage device and store and / or preprocess raw sensor values.Furthermore, the control system can include a cooling water pump, heat exchanger, cooling water circuit and / or a compressed air compressor, thus supplying the sensors directly with compressed air and / or cooling via the supply lines.
[0018] A further advantage is a traversing measuring system in which a drive system is arranged in a cabinet element, which is designed to move two measuring carriages synchronously by means of a mechanical coupling.
[0019] The drive system for the measuring carriages is advantageously integrated into the scanner frame housing within a cabinet element, positioned laterally next to the paper web. A drive system advantageously comprises an electric motor, a gearbox, and a drive shaft, which can be disconnected via a coupling device. This shaft drives a belt, chain, or threaded rod that positions the carriage in the transverse direction of the machine (CD). The sensors contained within the measuring carriage can thus be positioned on the paper web via the carriage, which is connected to the measuring carriage by means of a lateral bracket. The traversing measuring system is therefore able to determine a quality profile across the web width. Precise positioning of the upper and lower measuring carriages relative to each other is essential to achieve sufficient measurement quality.
[0020] A further advantage is a traversing measuring system in which the scanner frame includes a ventilation element and a dust filter, designed to draw in ambient air, filter it, and blow it into the scanner frame housing. The scanner frame can thus be operated with a slight overpressure of a few millibars, creating an airflow out of the housing at the side mounting point, which further helps to remove dust from the scanner frame. This slight airflow can also contribute to cooling the carriage and the components used, as well as to temperature equalization within the scanner frame, which is beneficial for stable measurement operation and reduces wear due to thermal stresses.
[0021] A traversing measuring system is also advantageous, wherein the traversing measuring carriage includes an angle adjustment device. Due to structural conditions, system configuration, and / or space constraints, the paper web may not run horizontally in the area of the traversing measuring system. Minor inclinations of the paper web relative to a horizontal path, within a range of ± 45° and especially within a range of 0 to ± 30°, can be compensated for by tilting the measuring carriage relative to the scanner frame. It is particularly advantageous if the angle adjustment device can adjust the measuring carriage in such a way that the center of gravity remains constant or largely constant. The mounting elements of the scanner frame on a foundation ("scanner feet") can be individually positioned.The frame includes prefabricated mounting elements in which the mounting plates can be positioned transversely to the machine (CD). This allows for easy mounting of the scanner frame on a foundation rail without the need for complex base constructions.
[0022] The scanner frame, or rather the two profiles arranged above and below the track and forming part of the scanner frame, essentially consists of a box girder reinforced with lateral plates that protrude beyond the box shape. This achieves particularly high rigidity of the structure and simultaneously creates installation space for the drive and guide components.
[0023] A further advantage is a traversing measuring system in which the housing is constructed in multiple parts and includes a cover. The cover is particularly advantageously positioned above the lateral mounting device and connected to the housing by a detachable screw connection or locking mechanism. The cover advantageously covers at least a large portion of the housing width in the transverse direction (CD) of the machine. The cover can also be composed of several individual parts. The cover allows for good accessibility for assembly or maintenance work.
[0024] A traversing measuring system is also advantageous, wherein the housing comprises a base body and a vertically arranged wall, the vertical wall having a plurality of openings. The integration of a vertical wall into the housing base body can significantly improve the stability, particularly the bending and torsional stability of the housing across its width in the transverse direction (CD) of the machine. It is particularly advantageous for a conveyor belt or belt to run in the space behind the measuring carriage, adjusting the carriage's position. The openings advantageously allow access to the space and are preferably round with a diameter of 100 mm to 200 mm. The wall is also advantageously connected to the lateral support devices to further improve stability. It is particularly advantageous for the wall to be made of steel or a metallic material with a material thickness of 0.5 to 8 mm.The wall is particularly advantageously welded into a curved base body or inserted using screw connections to create a force-fit connection.
[0025] A further advantage is a traversing measuring system, wherein the housing body comprises at least two bends in the machine transverse direction (CD), the bends having an angle (a) of 85°–95°. To achieve high stability in the machine transverse direction (CD), it is particularly advantageous to produce the housing body from a sheet of metal by bending. In particular, a box-shaped or C-shaped housing body can be produced, which is then welded only at the ends and / or at the connection to the central wall. The method of bending the housing has significant advantages over a welded housing, as fewer thermal stresses are introduced into the housing, and no deformations occur across the width in the machine transverse direction (CD).
[0026] The invention will be explained below with the aid of figures. The figures show, in detail:

[0028] Fig. 2: Isometric representation of the measuring system
[0029] Fig. 3: Partial sectional view of scanner frame
[0030] Fig. 4: Partial sectional view of the housing of the measuring system
[0031] Figure 1 shows an isometric, not-to-scale overview view of a traversing measuring system 1 according to the invention. The measuring system 1 comprises a scanner frame 2 that surrounds a paper web 12 for measuring quality values. Within the scope of this invention, the paper web 12 may also include a cardboard web, tissue web, pulp web, or fiber web. During production, the paper web 12 moves in the machine direction (MD), which in paper mills typically occurs at high production speeds in the range of 800 m / min to 2000 m / min. The scanner frame 2 comprises a measuring carriage 3, shown as the upper measuring carriage 4, wherein the measuring carriage 3 includes quality sensors for measuring the paper web 12. The quality sensors measure, for example, the following quality values of the paper web 12:
[0032] • Paper weight / basis weight [g / m²] 2 ]
[0033] • Humidity / Water content [%, g / m³] 2 ]
[0034] • Color values of the paper web
[0035] • Gloss measurement of the paper web
[0036] • Fiber orientation measurement
[0037] The measuring carriage 3 is moved by the measuring system 1 in a zigzag or wave pattern across the paper web 12 for measurement in the machine transverse direction CD. Figure 1 further shows the figure section plane A, which is shown in detail in Figure 3.
[0038] Figure 2 shows a schematic, non-scale isometric representation of the measuring system 1 according to the invention. The measuring system 1 comprises a scanner frame 2, which is shielded from the environment by means of a housing 18. The sides of the scanner frame 2 in the transverse direction CD of the machine each form a cabinet element 17, which are advantageously designed to be similar and / or of the same size on both sides. Thus, the cabinet elements 17 (not shown) can comprise a drive system 11 and / or a control device 20. Two movably arranged measuring carriages 3, an upper measuring carriage 4, and a lower measuring carriage 5 are located in the scanner frame 2. The measuring carriages 3, 4, 5 comprise sensors designed to detect quality values of a paper web 12 (not shown) and preferably transmit them digitally to a higher-level control system of a paper manufacturing plant.The paper web 12 is guided between the upper and lower measuring carriages 4, 5 in the machine direction MD. The measuring carriages 3, 4, 5 are each movably held in the scanner frame by a lateral retaining device 6. The measuring carriages can be moved in the transverse machine direction CD, and the gap from which the lateral retaining device 6 projects in the machine direction MD is advantageously sealed by a sealing strip and / or a sealing brush to prevent dust from entering the housing 18 of the scanner frame 2. The housing 18 can also include the cabinet elements 17 as a single unit, with parts of the housing 18 advantageously being designed as doors, maintenance hatches, or otherwise removable to facilitate maintenance and assembly work.The control device 20 advantageously comprises a display arranged in the housing 18 to advantageously display information locally about the operation, status and / or measured value of the traversing measuring system 1. The control device 20 further optionally, advantageously and not shown in the illustration, comprises communication means to communicate with a higher-level machine control system.
[0039] Figure 3 shows a schematic, non-scale partial sectional view of section plane A of the measuring system 1. The partial sectional view shows an upper measuring carriage 4 above the paper web 12, which is mounted on a carriage 7 by means of a lateral support 6. The carriage 7 is movably mounted on a rail 9 by means of a support roller 10 and is stabilized by a guide roller 11 on the rail 9. The arrangement of the measuring carriage 4 is advantageously on a center-of-gravity plane 19, which is defined by the rail 9 and the center of gravity of the measuring carriage. In the partial sectional view, the center-of-gravity plane 19 is represented two-dimensionally as the center-of-gravity axis 19. This minimizes the load on the guide roller 11 through good weight distribution and ensures smooth running of the measuring carriage 3.The carriage 7 is arranged within the housing 18 of the scanner frame 2, with the lateral support device 6 projecting out of the housing 18 in the machine direction MD. The one-sided suspension of the measuring carriage 3 is advantageous to reduce contamination within the housing 18. In the prior art, the measuring carriages 3 are mounted laterally on both sides or on the top and bottom of the scanner frame 2. This allows contaminants, in the paper industry usually paper dust containing minerals, to enter the scanner frame 2 and damage the bearing elements 8 of the carriage 7. Contaminants can also originate from process units upstream of the traversing measuring system; for example, coating lines and size presses can release ink mist, ink droplets, or starch residue into the environment, which can then reach the downstream scanner frame.Since a significant amount of dust is generated by dust carried along with the paper web, the side of the scanner frame 2 facing away from the machine direction MD is the side least prone to contamination. The gap through which the lateral support device exits the housing can be additionally and optionally sealed with a sealing strip and / or sealing brushes, and / or protected from ingress of dirt by an airflow (not shown in the illustration). The carriage 7 is advantageously mounted in the housing on two support rollers that run one behind the other on a lower rail of the rail assembly 9. The rails of the rail assembly 9 are supported by support elements 14, which are advantageously arranged every 200–900 mm in the transverse direction CD of the machine within the housing 9. An arrangement of support elements 14 every 400–700 mm, and especially every 500 mm, is particularly advantageous.The support elements 14 support the rails of the rail assembly and can compensate for deflection of the scanner frame 2 across the machine's transverse direction CD by means of an adjustment device (not shown), in particular by means of adjusting screws. This ensures that the distance between the upper measuring carriage 4 and the lower measuring carriage 5 remains constant, even on very wide machines. The lateral support 6 is advantageously and optionally connected to the measuring carriage 3 via an angle adjustment device 15, allowing the measuring carriage to be aligned accordingly if the paper web runs at an angle. The center of gravity 23 of the upper measuring carriage 4 is advantageously located below the lower supporting guide rail of the rail assembly 9. The center of gravity 23 of the lower measuring carriage 5 is located above the lower rail assembly 9, so that the weight of the lower measuring carriage is supported by the lower rail via a support roller 10.Inside the housing, a cable carrier 13 is shown, which can accommodate the supply lines of the measuring carriages 3, 4, 5 and is designed to guide the supply lines according to the position in CD of the measuring carriages 3, 4, 5. Figure 3 further shows a lower measuring carriage 5 which is arranged in the direction of gravity G under the paper web 12 and under the upper measuring carriage 4. The measuring carriages 3, 4, 5 advantageously and optionally include sensors that have a sensor component on both sides of the paper web 12. Examples of such two-part sensors are microwave humidity sensors, transmitted light sensors, or radiometric basis weight sensors. Precise positioning of the two measuring carriages 4, 5 one above the other is necessary; this can advantageously be achieved via a coupled drive system 16.The one-sided arrangement of the side support 6 offers the advantage that on the other side of the carriage 7, also protected from contamination, a drive system 16 is arranged which enables, for example by means of belts, chain or threaded rod, a precise synchronous movement of both measuring carriages 4, 5.
[0040] Figure 4 shows a schematic, non-scale partial sectional view of the measuring system 1 along section plane A, with only the upper part of the measuring system shown as an example. The housing 18 comprises a base body, a cover 24, and a wall 25. The base body of the housing 18 is bent at each corner at a bend 27, and the base body is constructed in one piece. The bend at the bend 27 advantageously spans an angle α of 90°, so that the housing 18 of the traversing measuring system 1 has a rectangular cross-section in the area of section plane A. The bend 27 advantageously forms a radius of typically R = 10 mm to R = 100 mm, resulting in a particularly dimensionally stable housing 18. The wall thickness of the housing 18 and the wall 25 is advantageously in the range of 1–10 mm, particularly in the range of 2–7 mm.The carriage 7 is movably mounted on the rail device 9 and is designed to move the measuring carriage 3 in the machine transverse direction (CD), while maintaining a relatively constant distance to the paper web. The wall 25 includes a plurality of openings 26 across the machine transverse direction (CD). These openings are optionally and advantageously round and have a diameter of 100–200 mm. The openings are each advantageously arranged between two support elements 14, thus providing access to the space behind them. This allows the condition of a conveyor belt to be inspected during maintenance. Reference numeral list.
