Abstract
Description
Technical Field
[0001] The present invention relates to a method for deburring the ends of a long profile according to the general item of claim 1, and a brush deburring machine for deburring the ends of a long profile according to the general item of claim 12.
Background Art
[0002] Methods and brush deburring machines for deburring the ends of long profiles are known for bar-shaped materials.
[0003] DE 10 2010 046 392 A1 describes a method in which a tube is conveyed along a roller brush by a conveying disk, whereby the edge of the tube is deburred by brushing. In the conveying disk system, the tube is transferred in an arc from one conveying disk to the other. During the arc-shaped conveyance along the roller brush, a displacement occurs in a direction perpendicular to the roller brush axis, which is the center of rotation of the roller brush. At the same time, the tube is rotated by a predetermined angle about its tube axis during conveyance. For example, in the case of conveying disk conveyance, the tube is rotated 90° when the conveying disk itself is rotated 90°.
[0004] The advantage of the conveying disk system is the arc-shaped conveying path, which enables more uniform deburring of the inner and outer edges of the end of the tube and at the same time a predetermined rotation of the tube. When the tube is positioned higher relative to the roller brush axis, the inner edge of the tube is deburred more, and when the tube is positioned lower than the roller brush axis, the outer edge of the tube is deburred more. In the case of the conveying disk system, it is preferable that the vertical average value of the arc-shaped conveying path is at the height of the roller brush axis, whereby the deburring of the inner and outer edges of the tube is performed uniformly. The disadvantage of this system is that the deburring of the inner edge and the deburring of the outer edge are always a compromise point. This applies particularly to long profiles with non-circular, square, rectangular, or other cross-sections.
Summary of the Invention
[0005] An object of the present invention, in a first aspect, is to provide a method for mitigating the aforementioned drawbacks.
[0006] In a second aspect, the object of the present invention is to provide a brush deburring machine that can mitigate the above-mentioned drawbacks.
[0007] In the first embodiment, this problem is solved by the method described at the beginning, with the features of claim 1.
[0008] The method according to the present invention is based on transporting at least one elongated object by a transport disk system along a transport path adjacent to at least one rotating roller brush. The elongated object is placed in the transport disk system and transported by the transport disk system in the transport direction. At least one roller brush is positioned such that its roller brush axis, which is the rotation center of the roller brush, extends along the transport direction, preferably parallel to the transport direction. The elongated object is deburred during transport by the rotating roller brush that contacts the ends of the elongated object.
[0009] According to the present invention, an adjustment device is provided, which, during deburring, adjusts the positions of at least one roller brush axis and the transport disk system relative to each other, preferably continuously, so that the distance profile traverses during the transport of at least one long object. Preferably, the distance profile between at least one roller brush axis and the transport disk system is predetermined according to the transport position of at least one long object.
[0010] Here, "continuous" is understood to mean during the transport or deburring of long objects along the transport disk system.
[0011] A distance profile means that the distance between the transport disk system and at least one roller brush axis is defined with respect to each position of at least one elongated object along the transport path in the transport disk system. The distance may be a longitudinal distance and / or a height distance along the height, or a combination of height distance and longitudinal distance.
[0012] Long pieces are first cut to length and have burrs on the cut surface before being subjected to the process according to the present invention. It is preferable that the long pieces have a constant cross-section along their longitudinal direction. In particular, the method according to the present invention is applicable to pipes having inner and outer edges on the cut surface, and the pipes have different cross-sections, for example, square or rectangular cross-sections, and preferably have rounded inner and outer corners.
[0013] In principle, distance profiles can be pre-set as needed, but it has been found that assigning a cross-section of a long object to a specific distance profile provides a good deburring effect.
[0014] The distance between the transport disc system and at least one roller brush axis can be determined in various ways. The reference point in distance measurement can be understood as the cheek of the transport disc system to which the transport disc is mounted, which remains spatially constant during transport. However, one or more axes of rotation of the transport disc can also be considered as reference points. Here, the choice of reference point is not necessarily important. It is preferable that the position of at least one roller brush axis be selected as another reference point. For example, the shortest distance between the two reference points is selected as the distance. However, it is also conceivable to consider only the horizontal or vertical distance component. Other distance concepts are also possible.
[0015] Preferably, the parameter value of a parameter representing the position of a component is assigned the distance between the transport disk system and at least one roller brush axis, from which the control device determines a control value for the positioning device. The parameter may be the angular position of the transport disk or the roller brush diameter, but other parameters are also possible.
[0016] In a preferred further development of the present invention, the angular position of the transport disc is assigned a height distance between the transport disc system and at least one roller brush axis, and the control device uses this height distance to determine a control value for an adjustment device, in particular for a height adjustment device.
[0017] Preferably, the transport position of at least one elongated object is determined by the angular position of the transport disc. The transport disc system has two rows of overlapping transport discs. Each transport disc has at least one recess, preferably exactly four. In other embodiments, there may be only one recess per transport disc. There are basically two process variations for transport by transport discs. In the first variation, each transport disc always moves forward by 90° in each cycle. In the second variation, the transport disc performing the transport rotates 90° forward each time, and the transport disc not currently performing the transport rotates 90° back at the moment when it can rotate without collision, preparing for the next elongated object. The advantage of the first variation is higher transport capacity. The advantage of the second variation is higher flexibility, because there are more different recesses and therefore more different elongated objects can be transported using a single transport disc. This means fewer tool changes are required.
[0018] Therefore, the angular position of the transport disk determines the angular position of the recess into which at least one end of an elongated object is inserted, thereby determining the position of at least one elongated object along at least a portion of the transport path. Since the movement of at least one elongated object is repeated periodically along the transport path, and especially since the transport path takes the form of cycloidal movement or is similar thereto, it is generally sufficient to determine only the angular positions of one or two adjacent transport disks to carry out the method according to the present invention.
[0019] The angular position of the transport disc is preferably determined via an angle sensor on the transport disc or on a shaft associated with the transport disc. In principle, other sensors for determining the angular position of the transport disc are also conceivable. In principle, other parameters can also be used to determine the position of at least one elongated object, for example, the position of at least one elongated object can be directly detected by optical means.
[0020] In another embodiment of the present invention, the diameter of at least one roller brush is assigned a length distance between the transport disk system and the roller brush shaft, and from that length distance, the control device determines a control value for an adjustment device, in particular for a length adjustment device. In this embodiment of the present invention, the position of the roller brush shaft is adjusted along the longitudinal direction, whereas in the method described above, the position of the roller brush shaft is adjusted along the vertical direction. Adjustment along the vertical direction takes into account the transport path along the transport disk system, which has a changing height, whereas adjustment along the longitudinal direction takes into account, for example, the fact that the roller brush may wear down over time and its diameter may decrease.
[0021] According to the present invention, length adjustment is the adjustment of the length distance between the roller brush or roller brush shaft and the conveyor disc system, particularly the next row of conveyor discs. By adjusting the length distance, for example, a reduction in the diameter of the roller brush during deburring can be taken into consideration. The penetration depth of the brush into at least one elongated end is advantageously maintained. According to the present invention, the length distance between the conveyor disc system and the longitudinal axis of the roller brush can be determined by determining the diameter of the roller brush as a parameter. The amount of protrusion of the elongated end beyond the conveyor disc can be predetermined before deburring, and the penetration depth can be advantageously set in advance.
[0022] In addition, of course, the distance between two rows of transport disks in the transport disk system can be adjusted to accommodate the different lengths of long objects inserted in different batches. This distance is preset to account for the protrusions of both long object ends beyond each row of transport disks. These length distances are then calculated by subtracting the insertion depth from the sum of the protrusion length and the radius of the roller brush.
[0023] While the adjustment of the distance between the transport disc row and the roller brush is already known in the prior art, this distance cannot be adjusted by an adjustment device during deburring.
[0024] Therefore, ideally, the adjustment device should include both a height adjustment device and a length adjustment device, and of course, these devices can be combined.
[0025] In a preferred embodiment of the method according to the present invention, a transport disk system simultaneously transports several elongated objects that are always positioned at the same vertical height. As a result, the height is adjusted in the same manner and with the same effect for all elongated objects that are inserted. Typically, adjacent transport disks in a transport disk system have the same angular position of their recesses, and elongated objects are preferably transported simultaneously only on adjacent transport disks.
[0026] Particularly preferably, at least one recess and at least one end portion of the elongated object of the transport disk are arranged such that at least one end portion of the elongated object is rotationally fixed within at least one recess, so that the elongated object is rotated about the longitudinal axis of the elongated object during transport, and their cross-sections are designed accordingly.
[0027] This method is particularly suitable for an elongated object that is non-rotatably attached within the recess facing the recess. For this purpose, the elongated object preferably has a non-circular cross-section, but preferably has a square cross-section such as a rectangular, square cross-section or a similar cross-section. During transport by the transport disk system, the elongated object attached at a position rotationally fixed with respect to the transport disk is gradually rotated about its own longitudinal axis so that circumferential deburring by a rotating roller brush becomes possible. However, in principle, the process is also suitable for an elongated object with a circular cross-section.
[0028] Particularly preferably, the position of at least one elongated object and the height distance between at least one roller brush axis and the transport disk system are synchronized in the distance profile. This can be done, for example, by selecting the height distance between at least one longitudinal axis of the elongated object and at least one roller brush axis to be zero for each position of at least one elongated object. However, this is only a special form of synchronization.
[0029] In another variant, for each position of at least one elongated object, the height distance between the lowest point of at least one elongated object and at least one roller brush axis can be set to a constant distance A.
[0030] However, other synchronizations are also conceivable. Preferably, for example, when the corner of the cross-section of the elongated object reaches the maximum height, the roller brush axis is raised and / or lowered by a predetermined distance to deburr the corner particularly well on its outer side and / or inner side, or when the corner of the cross-section of the elongated object reaches the minimum height, the roller brush axis is raised or lowered by a predetermined distance to deburr the corner particularly well on its inner side and / or outer side.
[0031] This operation is realized, in a second aspect, by means of a brushing machine with the features of claim 12.
[0032] The brushing machine according to the invention is suitable for carrying out one of the aforementioned methods. Conversely, the aforementioned methods are also suitable for implementation using one of the following brushing machines.
[0033] The brushing machine according to the invention for deburring the end portion of a long object comprises a conveying disk system for receiving at least one long object and for conveying at least one long object in a conveying direction. The conveying disk system has already been described in connection with the method, and its disclosure is also applicable to the brushing machine according to the invention. The brushing machine comprises at least one roller brush with a roller brush shaft extending along the conveying direction, and at least one roller brush contacts the end portion of at least one long object as described in connection with the method. The content disclosed in the method is also, in principle, applicable to the brushing machine according to the invention. It is preferred that at least one end portion of the long object is always in contact with at least one roller brush during the deburring process and is deburred by its rotation.
[0034] The brushing machine according to the invention comprises an adjusting device by means of which the relative positions of at least one roller brush shaft and the conveying disk system can preferably be continuously adjusted during deburring. Thereby, continuous adjustment of the relative positions, and thus improvement or intentional control of the deburring process, becomes possible.
[0035] Preferably, the distance profile between at least one roller brush shaft and the transport disk system is predetermined according to the transport position of at least one elongated object. This means that the distance between the roller brush shaft and the transport disk system is defined with respect to each transport position of at least one elongated object, and that the relative positions of at least one roller brush shaft and the transport disk system are continuously adjusted by an adjustment device so that the distance profile is traversed during the transport of at least one elongated object.
[0036] The positioning device is preferably an NC-controlled positioning device. The positioning device may preferably include a programmable control device. Parameter values representing the positions of the components can be input to the control device, which uses these parameter values to calculate control values for the positioning device and maintain a distance profile. The parameter values may be the aforementioned angular position of the transport disk or the diameter of the roller brush. However, other parameters are also possible.
[0037] While parameter values can be determined manually, it is preferable to monitor the parameters using sensors and continuously supply the parameter values to a control device. The control device uses these values to determine the relevant control values for the adjustment device and maintain a predetermined desired distance profile.
[0038] Ideally, the adjustment device is coupled to at least one roller brush and / or conveyor disc system. The adjustment device can be used to set the length or height distance of the roller brush alone under NC control, or, in addition to or instead of this, to set the height of the conveyor disc system.
[0039] As is typically done in transport disk systems, it is advantageous that, during transport, the recesses of adjacent transport disks (one disk apart) have the same angular position, and therefore, it is necessary to determine the angular position of only one transport disk, or up to two adjacent transport disks, as a parameter.
[0040] The present invention will be described with reference to two embodiments shown in 13 figures. [Brief explanation of the drawing]
[0041] [Figure 1] A perspective view of the basic structure of the brush deburring machine according to the present invention is shown. [Figure 2] A cross-sectional view along the line II-II in Figure 1 is shown at the raised position of the roller brush. [Figure 3] This figure is similar to Figure 2, but shows the roller brush in a lowered position. [Figure 4a.bc] This demonstrates the transport of two long objects with a square cross-section along a transport disc system with a fixed height for the roller brush axis, utilizing the latest technology. [Figure 5a.bc] Similar to Figure 4, but this figure shows the adjustment of the height distance between the roller brush shaft and the transport disk system according to the present invention, illustrating how the position of the long object shaft and the height of the roller brush shaft are synchronized with each other. [Figure 6a.bcd] The present invention provides a brush deburring machine with an adjustment device, wherein the position of the lowest edge of a rectangular long object and the height of the roller axis are synchronized with each other by having a constant distance between them. [Modes for carrying out the invention]
[0042] The brush deburring machine 1, schematically shown in Figure 1, is typically placed in a processing line for elongated objects 2, particularly elongated metal objects 2, especially pipes, especially pipes with square, triangular, or hexagonal cross-sections. The elongated objects 2 are first cut to precise lengths by a pipe cutting machine (not shown). The cut surfaces of the elongated object ends 2a,2b have undesirable burrs along the inner edge 13b and outer edge 13a in the case of pipes. In the case of solid objects, burrs occur only on the outer edge. The task of the brush deburring machine is to remove the burrs from the inner edge 13a and outer edge 13b of the pipe cut to length by brushing. For this purpose, the elongated objects 2 are supplied individually to the brush deburring machine 1.
[0043] The brush deburring machine 1 has two opposing parallel rows 5a and 5b of transport discs, each row consisting of four transport discs 3a, 3b, 3c, and 3d. Each row of transport discs 5a and 5b has a supply disc 4a at the inlet and a removal disc 4b at the outlet, and these discs allow the long object 2 to be fed in and discharged. The transport discs 3a, 3b, 3c, and 3d in rows 5a and 5b overlap. Preferably, each of the transport discs 3a, 3b, 3c, and 3d has four recesses 6a, 6b, 6c, and 6d, as shown in Figure 4, for example. Preferably, the cross-section of each recess 6a, 6b, 6c, and 6d is matched to the outer cross-section of the long object 2.
[0044] The long object 2 is inserted into the transport disk system along its longitudinal axis in the longitudinal direction L, and transported along the transport direction T which is perpendicular to the longitudinal direction L, and deburred in the process.
[0045] The brush deburring machine 1 according to the present invention is particularly suitable for deburring elongated objects 2 with a non-circular cross-section, but is not limited thereto. It is convenient that the inner cross-section of each recess 6a, 6b, 6c, 6d is matched to the outer cross-section of the elongated object 2, thereby ensuring that the elongated object 2 is positioned non-rotatably within the recesses 6a, 6b, 6c, 6d. For this purpose, the outer cross-section of the elongated object 2 shown in Figure 4 is, for example, non-circular or arc-shaped, and is complementary in some areas to the inner cross-sections of the recesses 6a, 6b, 6c, 6d, thereby preventing relative rotational movement between the recesses 6a, 6b, 6c, 6d and the elongated object 2 during transport.
[0046] Figure 1 shows that the movement of the elongated object 2 in the transport direction T is performed by continuous circular motion, which is referred to here as a cycloidal path even if it deviates from a strictly defined cycloidal path. In particular, the height H of the elongated object 2 changes during transport. Here, height H is understood as the distance from a constant horizontal line, preferably the ground.
[0047] In the prior art, roller brushes 7a and 7b are assigned to opposing rows 5a and 5b of the transport disk, respectively, so that the roller brush axes 8a and 8b, which are the rotation centers of each roller brush 7a and 7b, are arranged along the transport direction T of the elongated object 2, preferably parallel to the transport direction T. As shown in Figure 1, the roller brushes 7a and 7b rotate to deburr the end 2a of the elongated object.
[0048] According to the present invention, on the one hand, the length setting device 9a sets the longitudinal length distance l between the inserted elongated end 2a and the outer surfaces of the roller brushes 7a and 7b, and on the other hand, the height setting device 9b sets the height distance h of the roller brushes 7a and 7b relative to the transport disk system 11. The adjustment device 9 comprises a length adjustment device 9a and a height adjustment device 9b. The respective movability of the roller brushes 7a and 7b resulting from the adjustment is indicated by the corresponding double arrows.
[0049] Furthermore, the distance a between the two rows 5a and 5b of the transport disc can be changed and adjusted in advance to first fit with the elongated object 2 that has been cut to length.
[0050] Figures 2 and 3 illustrate the function of the height adjustment device 9b, which adjusts the height distance h between the transport disc system 11 and the roller brush shaft 8a. The height H of the transport disc system is measured, for example, relative to the ground, or the underside of the lateral teak to which the transport discs 3a, 3b, 3c, and 3d are rotatably mounted is used as the zero line for height H. However, the height H of one of the transport disc shafts can also be used as the zero line for height H.
[0051] Figure 2 shows the end portion 2a of the elongated object, which forms the shape of a tube end inserted into the transport disk system 11. The transport disk system 11 itself is not shown; only the lateral projection U of the elongated object 2 extending beyond the transport disk is visible. In Figure 2, the roller brush shaft 8a is positioned above the elongated object shaft 12 along the height H. When the roller brush shaft 8a is positioned above the elongated object shaft 12, as shown in Figure 2, it is preferable that the outer edge 13a of the elongated object end portion 2a deburrs during the rotational movement of the roller brush 7a.
[0052] Figure 3 shows the changed position of the roller brush shaft 8a compared to Figure 2. In Figure 3, the roller brush shaft 8a is lowered, and in this case, for convenience, the upper and lower ends point towards the ground. In the lowered position of the roller brush shaft 8a shown in Figure 3, the inner edge 13b of the end 2a of the long object is deburred particularly well.
[0053] The present invention is advantageously applicable to hollow objects. A hollow object, in this context, is understood to be a tubular object with any desired cross-section.
[0054] The height distance h between the transport disk system 11 and the roller brush shaft 8a is adjustable by the height adjustment device 9b. The length distance l between the end of the long object 2a and the outer surface of the roller brush 7a is adjustable by the length adjustment device 9a. It is preferable that both the length adjustment device and the height adjustment devices 9a and 9b are NC controlled so that parameter values can be input to the control device in the transport direction T along the transport disk system 11, the control device calculates a distance profile from the parameter values, for example interpolates them, and uses these values to control the adjustment device, which continuously adjusts the height distance h between the transport disk system 11 and the roller brush shaft 8a during transport according to a predetermined distance profile.
[0055] The transport disk system 11 is preferably equipped with two roller brushes 7a and 7b, as shown in Figure 1. It is preferable that both roller brushes 7a and 7b are similarly controlled by the height adjustment device 9b. The same may apply to the length adjustment device 9a. The adjustment device 9 can control only the positions of the roller brushes 7a and 7b, only the position of the transport disk system 11, or both positions.
[0056] Figure 4 shows the transport of a long object 2, which has the form of a tube with a nearly square cross-section, in the transport direction T. In this case, "square" is understood not as a strictly square, but as a square with rounded corners. The long object 2 is placed in recesses 6a, 6b, 6c, 6d so that it cannot rotate relative to the transport discs 3a, 3b, 3c, 3d during transport. The transport discs 3a, 3b, 3c, 3d rotate around their own axes of rotation, and each time the long object 2 rotates 90°, it is passed to the next transport disc 3a, 3b, 3c, 3d. As a result, the long object 2 also rotates 90° with each transport disc, and after being transported along the four transport discs 3a, 3b, 3c, 3d, the long object 2 rotates 360° relative to the fixed spatial coordinate system. This enables uniform deburring in the circumferential direction of the end 2a of the long object.
[0057] Figure 4a shows the 0° position of the transport discs 3a, 3b, 3c, and 3d, Figure 4b shows the 45° position of the transport discs 3a, 3b, 3c, and 3d, and Figure 4c shows the 180° position of the transport discs 3a, 3b, 3c, and 3d. The movement of the center of the elongated object 2 is shown as a dashed cycloid line. In the longitudinal direction L corresponding to the top view in Figures 4a, 4b, 4c, and 4d, the elongated object axis 12 of the elongated object 2 moves in an approximately cycloidal manner. In the prior art, the position of the roller brush axis 8a remains unchanged with respect to each position of the elongated object 2 in Figures 4a, 4b, and 4c. As a result, the elongated object axis 12 of the elongated object 2 reciprocates between a position above the roller brush axis 8a (Figure 4b) and a position below the roller brush axis 8a (Figures 4a and 4c). As a result, deburring of the inner edge 13b may be better in some cases, while deburring of the outer edge 13a may be better in others.
[0058] Figure 5 shows the brush deburring process according to the present invention with the adjustment device 9 according to the present invention in special programming. The position of the elongated object axis 12 and the position of the roller brush axis 8a are synchronized along the height H. The height distance h is zero, and the elongated object axis 12 and the roller brush axis 8b always intersect perpendicularly during transport. In this case, this means that the height of the roller brush axis 8a and the height of the center point of the elongated object 2 are always the same. This is also true for the 0° position in Figure 5a, the 45° position in Figure 5b, and the 180° position in Figure 5c. Since the elongated object 2 itself rotates around its own axis during transport, both the inner edge 13b and the outer edge 13a of the elongated object end 2a are deburred very uniformly.
[0059] To understand Figures 5a, 5b, 5c, and 5d, it should be noted that adjacent transport disks 3a and 3c, with one disk space between them, are firmly coupled to each other and rotate in the same direction. On the other hand, the remaining adjacent transport disks 3b and 3d, with one disk space between them, remain stationary, pick up the long object 2, rotate while firmly coupled, and continue to rotate in the same manner, while adjacent transport disks 3a and 3c, with one disk space between them, remain stationary.
[0060] Figures 6a, 6b, 6c, and 6d show further embodiments of the brush deburring process according to the present invention at four different positions on the transport disks 3a, 3b, 3c, and 3d.
[0061] Figure 6a shows the positions of transport discs 3a, 3b, 3c, and 3d at 0°, Figure 6b at 40°, Figure 6c at 60°, and Figure 6d at 80°. Figure 6d shows the positions of transport discs 3a, 3b, 3c, and 3d immediately before the transfer of the long object 2 from one transport disc 3a, 3c to the adjacent transport disc 3b, 3d. The recesses 6a, 6b, 6c, and 6d of the transport discs 3a, 3b, 3c, and 3d are not circular, but are fitted to the square cross-section of the long object 2, thereby allowing the long object 2 to be transported within the recesses 6a, 6b, 6c, and 6d while its rotation is fixed relative to each transport disc 3a, 3b, 3c, and 3d.
[0062] The method in Figure 6 utilizes the fact that the long object axis 12 undergoes cycloidal movement in the transport direction T, and the height H of the roller brush axis 8a is adapted to this movement. The height distance h of the roller brush axis 8a from the long object axis 12 is variable, and is selected such that the distance A of the roller brush axis 8a from the lowest point of the recesses 6a, 6b, 6c, 6d where the long object 2 is currently being transported remains constant.
[0063] Of course, other distance profiles are also possible.
[0064] In particular, not only the height distance h of the roller brush shafts 8a and 8b, but also their length distance l can be changed. This takes into account, for example, the fact that the roller brushes 7a and 7b deteriorate over time and the brushes become shorter, thereby causing the roller brush shafts 8a and 8b to move closer to the respective rows 5a and 5b of the transport discs over time, and as a result, the distance between the roller brushes 7a and 7b and the end of the long object being deburred 2a remains the same.
[0065] The distance profile can be decomposed into a height distance profile and a length distance profile. Parameters are specified, parameter values are determined, and from these parameter values, the control device calculates the adjustment values for the adjustment device, thereby determining the distance profile. These parameters can be, for example, the angular positions of the transport discs 3a, 3b, 3c, and 3d. The angular positions of the transport discs 3a, 3b, 3c, and 3d are used to determine the position of the center point of the recesses 6a, 6b, 6c, and 6d to which the long object 2 is to be transported. The height of the center point of the recesses 6a, 6b, 6c, and 6d corresponding to the position of the long object axis 12 of the long object 2 is equal to the height of both roller brush axes 8a and 8b. This corresponds to the method shown in Figure 5. Alternatively, the position of the lowest point of the recess 6a, 6b, 6c, and 6d that is currently transporting one of the long objects 2 can be assigned to each angular position of the transport discs 3a, 3b, 3c, and 3d. A distance A is added to this lowest point, and the determined position corresponds to the height of the two roller brush axes 8a and 8b. Of course, various other methods can be considered to allow the distance profile to be determined from the angular position and other parameters. [Explanation of Symbols]
