Description

[0001] Process for deburring long profile ends and a brush deburring machine

[0002] The invention relates to a method for deburring long profile ends of long profiles according to the preamble of claim 1 as well as to a brush deburring machine for deburring long profile ends of long profiles according to the preamble of claim 12.

[0003] Processes for deburring long profile ends as well as brush deburring machines are known for rod-shaped material.

[0004] DE 10 2010 046 392 A1 describes a process in which pipes are transported along roller brushes using conveyor discs, thus deburring the pipe edges. In this conveyor disc system, the pipes are transferred in an arc from one conveyor disc to the other. During the arc-shaped transport along the roller brushes, there is a vertical displacement relative to the roller brush axis, around which the roller brush rotates. At the same time, the pipe is rotated around its pipe axis by a defined angle during transport. For example, with conveyor disc transport, the pipe is rotated by 90° when the conveyor disc itself is rotated by 90°.

[0005] The advantage of the conveyor disc system is the curved transport path, which enables more even deburring of the inner and outer edges of the pipe end while simultaneously performing the defined rotation of the pipe. If the pipe is positioned higher relative to the roller brush axis, the inner edge of the pipe is deburred more intensively; if the pipe is positioned lower than the roller brush axis, the outer edge of the pipe is deburred more intensively. With the conveyor disc system, the vertical mean value of the curved transport path is preferably at the height of the roller brush axis, so that the deburring of the inner and outer edges of the pipe is carried out evenly. The disadvantage of this system is that deburring the inner edge and deburring the outer edge always represent a compromise. This particularly applies to long profiles with a non-circular cross-section, such as a square, rectangular, or other shape.

[0006] The object of the present invention is, in a first aspect, to provide a method that mitigates the above-mentioned disadvantages. In a second aspect, the object of the present invention is to provide a brush deburring machine with which the above-mentioned disadvantages can be mitigated.

[0007] In its first aspect, the object is achieved by a method as mentioned above having the features of claim 1.

[0008] The method according to the invention is based on transporting the at least one elongated profile using a transport disc system along a transport path adjacent to the at least one rotating roller brush. The elongated profile is placed in the transport disc system and transported in a transport direction by means of the transport disc system. The at least one roller brush is arranged with its roller brush axis, around which the roller brush rotates, extending along the transport direction, preferably parallel to it. The elongated profile is deburred during transport by the rotating roller brush, which makes contact with the end of the elongated profile.

[0009] According to the invention, an adjusting device is provided that preferably continuously adjusts the positions of the at least one roller brush axis and the transport disk system relative to each other during deburring, preferably such that a spacing profile is traversed during the transport of the at least one long profile. The spacing profile between the at least one roller brush axis and the transport disk system is preferably predetermined depending on a transport position of the at least one long profile.

[0010] 'Continuously' is understood here as during the transport of the long profile along the transport disc system or during deburring.

[0011] A distance profile means that for each position of the at least one long profile along the transport path in the transport disc system, a distance is specified between the transport disc system and the at least one roller brush axis. A distance can be a length distance in a longitudinal direction and / or a height distance along a height, or a combination of height and length distance.

[0012] The long profiles are first cut to length and have burrs on the cut surfaces before being subjected to the method according to the invention. They preferably have a consistent cross-section along their longitudinal direction. In particular, the method according to the invention is applicable to pipes with inner and outer edges at the cut surfaces, wherein the pipes have different cross-sections, for example, square or rectangular cross-sections, preferably with rounded inner and outer corners.

[0013] In principle, the spacing profile can be specified as desired, although it has been found that cross-sections of long profiles assigned to certain spacing profiles achieve good deburring results.

[0014] The distance between the transport disc system and the at least one roller brush axis can be determined in different ways. The reference point for measuring the distance can be the cheeks of the transport disc system, which remain constant in space during transport and from which the transport discs are suspended. However, one or more axes of rotation of the transport discs can also be considered as a reference point. Which reference point is chosen is not really important. The position of the at least one roller brush axis is preferably chosen as another reference point. For example, the shortest distance between the two reference points is chosen as the distance. However, only the horizontal or vertical distance components can also be considered. Other distance concepts are also conceivable.

[0015] Preferably, parameter values ​​describing the position of components are assigned to distances between the transport disc system and the at least one roller brush axis, and a control device determines control values ​​for the actuating device from the distances. The parameters can be the angular positions of the transport discs or the roller brush diameter; other parameters are also conceivable.

[0016] In a preferred development of the invention, angular positions of the transport discs are assigned to height distances between the transport disc system and the at least one roller brush axis, and a control device determines control values ​​for the adjusting device, in particular for a height adjusting device, from the height distances.

[0017] The transport position of the at least one long profile is preferably determined by the angular positions of the transport discs. The transport disc system has two rows of overlapping transport discs. Each of the transport discs has at least one recess, preferably exactly four recesses. In other embodiments, only one recess may be provided per transport disc. There are basically two process variants for transport using the transport discs. In the first variant, each transport disc moves forward 90° in cycles. In the second variant, the transport discs that are currently transporting rotate forward 90°, and the transport discs that are not currently transporting rotate back 90° the moment they can rotate without collision, in order to be ready for the next profile. The advantage of the first variant is higher transport performance.The advantage of the second variant is greater flexibility, because there are more different recesses, allowing more different profiles to be transported with one conveyor disc. Fewer tool changes are therefore required.

[0018] The angular position of the transport discs thus determines the angular position of the recess into which the at least one long profile end is inserted and thus the position of the at least one long profile along at least part of the transport path. Since the movement of the at least one long profile along the transport path repeats periodically, particularly because the transport path has the shape of or is similar to a cycloidal movement, determining the angular position of one or two adjacent transport discs is generally sufficient to implement the method according to the invention.

[0019] The angular position of the transport discs is preferably determined via an angle sensor on the transport disc or a shaft associated with the transport discs. In principle, other sensors for determining the angular position of the transport discs are also conceivable. In principle, other parameters can also be used to determine the position of the at least one long profile; for example, the position of the at least one long profile could be detected directly optically.

[0020] In another embodiment of the invention, diameters of the at least one roller brush are assigned longitudinal distances between the transport disk system and the roller brush axis, and the control device determines control values ​​for the adjusting device, in particular for a length adjusting device, from the longitudinal distances. In this embodiment of the invention, the position of the roller brush axis is adjusted along the longitudinal direction, while in the aforementioned method it is adjusted along the vertical direction. The adjustment along the vertical direction takes into account the height-varying transport path along the transport disk system, while the adjustment along the longitudinal direction takes into account that, for example, the roller brushes can wear over time and thus reduce in diameter.

[0021] According to the invention, the length adjustment involves adjusting the longitudinal distance between the roller brush or roller brush axis and the transport disc system, in particular the next row of transport discs. By adjusting the longitudinal distance, for example, the decreasing diameter of the roller brush during deburring can be taken into account. In this case, the engagement depth of the brush in the at least one long profile end is advantageously maintained. According to the invention, the diameter of the roller brush can be determined as a parameter in order to establish a longitudinal distance between the transport disc system and the roller brush longitudinal axis. Any projection of the long profile end beyond the transport discs is predetermined before deburring, and the engagement depth can advantageously be set in advance.

[0022] In addition, the two rows of conveyor discs in the conveyor disc system are also adjustable in their spacing to accommodate the different lengths of the inserted long profiles from different batches. The spacing is pre-set, taking into account the overhang of both long profile ends beyond the respective row of conveyor discs. Their longitudinal spacing is then the length of the overhang plus a roller brush radius, minus the engagement depth.

[0023] The adjustment of the distance between a row of transport discs and the roller brush is known in principle in the prior art, but not in such a way that the distance can also be adjusted during deburring by means of an adjusting device.

[0024] The adjustment device therefore advantageously includes the height adjustment device and the length adjustment device, which can of course also be combined.

[0025] In a preferred embodiment of the method according to the invention, the transport disc system simultaneously transports several long profiles, which are always positioned at the same height below one another. As a result, the height is adjusted in the same way and with the same effect for all inserted long profiles. Typically, the next but one transport discs in the transport disc system have the same angular position of their recesses, and the long profiles are preferably only transported simultaneously on each next but one transport disc. Particularly preferably, the at least one recess in the transport discs and the at least one long profile end are designed in their cross-sections such that the at least one long profile end is arranged in a rotationally fixed manner in the at least one recess, and the long profile is thus rotated about a long profile axis during transport.

[0026] The process is particularly suitable for long profiles that are non-rotatably mounted in and opposite the recesses. For this purpose, the long profiles preferably have angular cross-sections, such as rectangular, square, or similar, rather than circular ones. During transport with the transport disc system, the long profiles, which are non-rotatably mounted opposite the transport discs, are gradually rotated around their own longitudinal axis, allowing circumferential deburring by the rotating roller brushes. However, the process is also generally suitable for long profiles with a circular cross-section.

[0027] Particularly preferably, the positions of the at least one long profile and the height distances between the at least one roller brush axis and the transport disk system are synchronized in the distance profile. This can be achieved, for example, by selecting zero for the height distance between the at least one long profile axis and the at least one roller brush axis for each position of the at least one long profile. However, this is only a special form of synchronization.

[0028] In another variant, for each position of the at least one long profile, the height distance between a lowest point of the at least one long profile and the at least one roller brush axis could be set to a constant distance A.

[0029] However, other synchronizations are also conceivable. Preferably, the roller brush axis is raised and / or lowered a defined distance when a corner of the long profile cross-section has reached a maximum height, for example, to deburr the corner particularly well on the outside and / or inside, or raised or lowered a defined distance when a corner of the long profile cross-section has reached a minimum height to deburr the corner particularly well on the inside and / or outside.

[0030] The object is achieved in its second aspect by a brush deburring machine having the features of claim 12. The brush deburring machine according to the invention is suitable for carrying out one of the above-mentioned methods. Conversely, the above-mentioned methods are suitable for carrying out one of the following brush deburring machines.

[0031] The brush deburring machine according to the invention for deburring long profile ends of a long profile comprises a transport disc system for receiving the at least one long profile and for transporting the at least one long profile in a transport direction. The transport disc system has already been described in connection with the method; the disclosure also applies mutatis mutandis to the brush deburring machine according to the invention. The brush deburring machine comprises at least one roller brush with a roller brush axis running along the transport direction, wherein the at least one roller brush is in contact with the long profile end of the at least one long profile, as described in connection with the method. The disclosure therein also applies in principle mutatis mutandis to the brush deburring machine according to the invention.During the deburring process, the at least one long profile end is preferably in constant contact with the at least one roller brush and is deburred by its rotation.

[0032] The brush deburring machine according to the invention comprises an adjusting device with which the positions of the at least one roller brush axis and the transport disk system relative to each other can preferably be continuously adjusted during deburring. This allows for continuous adjustment of the relative positions and thus an improvement or deliberate control of the deburring process.

[0033] Preferably, a spacing profile between the at least one roller brush axis and the transport disk system is predetermined depending on a transport position of the at least one long profile. This means that for each transport position of the at least one long profile, a distance between the roller brush axis and the transport disk system is defined, as well as an adjusting device that continuously adjusts the positions of the at least one roller brush axis and the transport disk system relative to one another in such a way that the spacing profile is traversed during the transport of the at least one long profile.

[0034] The actuator is preferably an NC-controlled actuator. The actuator can advantageously include a control device, which is preferably programmable. Parameter values ​​describing the position of components can be entered into the control device, and the control device calculates control values ​​for the actuator from these values ​​in order to maintain the spacing profile. The parameter values ​​can be the aforementioned angular position of the transport discs or the diameter of the roller brush. However, other parameters are also conceivable.

[0035] The parameter values ​​can be determined manually, but it is preferably provided that the parameters are monitored by sensors and parameter values ​​are continuously fed to the control device, which then determines the corresponding control values ​​for the actuating device in order to maintain the desired distance profile, which is specified in advance.

[0036] Advantageously, the adjusting device is coupled to the at least one roller brush and / or the transport disc system. The adjusting device can be used to adjust the length or height of only the roller brush using NC control, or also, or alternatively, the height of the transport disc system.

[0037] Advantageously, it is provided that recesses of the next but one transport discs, as is usual in transport disc systems, have an identical angular position among each other during transport, so that the angular position of only one transport disc, or at most of two adjacent transport discs, needs to be determined as a parameter.

[0038] The invention is described using two exemplary embodiments in 13 figures. These show:

[0043] Fig.5a,b,c View as in Figures 4 but with height adjustment according to the invention between roller brush axis and transport disc system, wherein a position of the long profile axis and a height of the

[0044] Roller brush axis are synchronized with each other,

[0045] Fig.6a,b,c,d show a brush deburring machine with the adjusting device according to the invention, wherein a position of a lowermost edge of the square profile and a height of the roller axis are synchronized with each other by having a constant distance.

[0046] The brush deburring machine 1, shown schematically in Fig. 1, is typically arranged within a processing line for long profiles 2, in particular metallic long profiles 2, in particular pipes, in particular pipes with a square, triangular, or hexagonal cross-section. The long profiles 2 are first cut to exact length by a pipe cutting machine (not shown). The cutting surfaces of long profile ends 2a, 2b of pipes have unwanted burrs along an inner edge 13b and an outer edge 13a. In the case of solid profiles, only an outer edge with burrs is created. The task of the brush deburring machine is to remove the burrs from the inner and outer edges 13a, 13b of the cut pipes by brushing. The long profiles 2 are fed individually to the brush deburring machine 1 for this purpose.

[0047] The brush deburring machine 1 has two opposing parallel rows of transport discs 5a, 5b, each comprising four transport discs 3a, 3b, 3c, 3d. Each of the rows of transport discs 5a, 5b has a feed disc 4a at an inlet and a removal disc 4b at an outlet, which enable the feeding and ejection of the long profile 2. The transport discs 3a, 3b, 3c, 3d of a row of transport discs 5a, 5b overlap. Each of the transport discs 3a, 3b, 3c, 3d preferably has four recesses 6a, 6b, 6c, 6d, as shown, for example, in Fig. 4. Preferably, a cross-section of each recess 6a, 6b, 6c, 6d is adapted to an outer cross-section of the long profile 2.

[0048] The long profiles 2 are inserted into the transport disc system in the longitudinal direction L, which corresponds to their longitudinal axis, and are transported along a transport direction T, which is aligned perpendicular to the longitudinal direction L, and are deburred in the process.

[0049] The brush deburring machine 1 according to the invention is particularly suitable for deburring long profiles 2 with a non-circular cross-section, but is not limited thereto. Advantageously, an inner cross-section of each recess 6a, 6b, 6c, 6d is adapted to an outer cross-section of the long profile 2, so that the long profile 2 is arranged in the recess 6a, 6b, 6c, 6d in a rotationally fixed manner. For this purpose, the outer cross-sections of the long profiles 2, which are shown in Fig. 4, must, for example, not be circular or arcuate, and must be partially complementary to the inner cross-sections of the recesses 6a, 6b, 6c, 6d, so that a relative rotational movement between the recesses 6a, 6b, 6c, 6d and the long profiles 2 is prevented during transport.

[0050] Figure 1 shows that the movement of the long profiles 2 in the transport direction T occurs in successive arcuate movements. These are also referred to here as cycloidal trajectories, even though they deviate from the strict form of a cycloidal trajectory. In particular, the long profiles 2 change their height H during transport. Height H is understood here as a distance from a constant horizontal, preferably the ground.

[0051] It is known in the prior art that each of the opposing conveyor disc rows 5a, 5b is assigned a roller brush 7a, 7b, wherein each roller brush axis 8a, 8b, around which the respective roller brush 7a, 7b rotates, is arranged along the axis, preferably parallel to the transport direction T of the long profiles 2. The roller brush 7a, 7b rotates and deburrs the long profile ends 2a, as shown in Fig. 1.

[0052] According to the invention, it is provided, on the one hand, to adjust a length distance I in the longitudinal direction L between the inserted long profile ends 2a and an outer side of the roller brush 7a, 7b by means of a length adjustment device 9a and, on the other hand, to adjust a height distance h of the roller brush 7a, 7b relative to the transport disc system 11 by means of a height adjustment device 9b. An adjustment device 9 comprises the length adjustment device 9a and the height adjustment device 9b. The respective movement possibilities of the roller brushes 7a, 7b generated by the adjustment are represented by associated double arrows.

[0053] In addition, a distance a between the two rows of transport discs 5a, 5b can be changed and pre-adjusted in order to initially adapt to the cut-to-length long profiles 2.

[0054] Figures 2 and 3 show the function of the height adjustment device 9b, which adjusts the height distance h between the transport disc system 11 and the roller brush axis 8a. The height H of the transport disc system is measured, for example, relative to the ground, or the underside of lateral cheeks on which the transport discs 3a, 3b, 3c, 3d are rotatably suspended is used as the zero line of the height H. However, the height H of one of the transport disc axes can also be used as the zero line of the height H.

[0055] Fig. 2 shows the long profile end 2 in the form of a pipe end, which is inserted into the transport disc system 11. The transport disc system 11 itself is not shown; only a lateral projection Ü of the long profile 2 beyond the transport disc can be seen. In Fig. 2, the roller brush axis 8a is arranged along the height H above a long profile axis 12. If the roller brush axis 8a is arranged above the long profile axis 12, as shown in Fig. 2, the outer edge 13a of the long profile end 2a is preferably deburred during a rotational movement of the roller brush 7a.

[0056] Fig. 3 shows a modified position of the roller brush axis 8a compared to Fig. 2. The roller brush axis 8a in Fig. 3 is lowered downward, with top and bottom advantageously referring to the direction toward the ground. With the lowered position of the roller brush axis 8a shown in Fig. 3, an inner edge 13b of the long profile end 2a is deburred particularly well.

[0057] The invention is advantageously applicable to hollow profiles. Hollow profiles are understood here to be tubular profiles with any cross-section.

[0058] The height distance h between the transport disc system 11 and the

[0059] Roller brush axis 8a is adjustable using the height adjustment device 9b.

[0060] The length distance I between the long profile end 2a and an outer surface of the roller brush 7a is adjustable by the length adjustment device 9a. The adjustment device 9, as well as the length and height adjustment devices 9a, 9b, are preferably NC-controlled, so that a parameter value in the transport direction T along the transport disc system 11 can be entered into a control device. The control device calculates a distance profile from the parameter values, for example, interpolates it, and uses these values ​​to control the adjustment device, which continuously adjusts a height distance h between the transport disc system 11 and the roller brush axis 8a during transport according to the given distance profile.

[0061] Conveniently, the transport disc system 11 comprises two roller brushes 7a, 7b, as shown in Fig. 1. Conveniently, both roller brushes 7a, 7b are controlled in the same way by means of the height adjustment device 9b. The same applies to the length adjustment device 9a. The adjustment device 9 can either control only the position of the roller brushes 7a, 7b, or only the position of the transport disc system 11, or even control both.

[0062] Fig. 4 shows the transport of long profiles 2 in the form of pipes with an approximately square cross-section in the transport direction T, where square is not to be understood as strictly square, but as a square with rounded corners. The long profile 2 is arranged in the recesses 6a, 6b, 6c, 6d in a rotationally fixed manner relative to the transport disks 3a, 3b, 3c, 3d during transport. Due to the rotation of the transport disks 3a, 3b, 3c, 3d about their own axis of rotation and the transfer of the long profile 2 to the next transport disk 3a, 3b, 3c, 3d after each 90° rotation, the long profile 2 is also rotated by 90° for each transport disk. After transport along four transport disks 3a, 3b, 3c, 3d, the long profile 2 has been rotated by 360° relative to a fixed spatial coordinate system. This enables uniform, circumferential deburring of the long profile end 2a.

[0063] Fig. 4a shows a 0° position of the transport discs 3a, 3b, 3c, 3d, Fig. 4b a 45° position of the transport discs 3a, 3b, 3c, 3d and Fig. 4c the 180° position of the transport discs 3a, 3b, 3c, 3d. The movement of the centers of the elongated profiles 2 is shown as a dashed cycloidal line. The elongated profile axis 12 of the elongated profile 2 moves approximately cycloidally when viewed in the longitudinal direction L, which corresponds to the top view in Figs. 4a, 4b, 4c, 4d. In the prior art, the position of the roller brush axis 8a remains unchanged for every position of the elongated profile 2 in Figs. 4a, 4b, 4c. As a result, the long profile axis 12 of the long profile 2 oscillates back and forth between a position above the roller brush axis 8a (Fig. 4b) and positions below the roller brush axis 8a (Figs. 4a, 4c). This results in better deburring of the inner edges 13b and outer edges 13a.

[0064] Fig. 5 shows the brush deburring method according to the invention with the adjusting device 9 according to the invention in a special programming. The position of the long profile 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 long profile 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 long profile 2 are always the same. This is the case in the 0° position according to Fig. 5a, in the 45° position according to Fig. 5b, and in the 180° position according to Fig. 5c. Since the long profile 2 rotates about its own axis during transport, a fairly uniform deburring of both the inner edge 13b and the outer edge 13a of the long profile end 2a is achieved.

[0065] To understand Figures 5a, 5b, 5c, and 5d, it should be noted that the next but one transport discs 3a and 3c are firmly coupled to each other and rotate at the same speed. Meanwhile, the remaining next but one transport discs 3b and 3d remain stationary, pick up the long profile 2, and then continue to rotate firmly coupled and at the same speed, while the next but one transport discs 3a and 3c remain stationary.

[0066] Figures 6a, 6b, 6c, 6d show a further embodiment of the brush deburring method according to the invention in four different positions of the camouflage discs 3a, 3b, 3c, 3d.

[0067] Fig. 6a shows the position of the transport discs 3a, 3b, 3c, 3d at 0°, Fig. 6b at 40°, Fig. 6c at 60° and Fig. 6d at 80°. Fig. 6d shows the position of the transport discs 3a, 3b, 3c, 3d shortly before the transfer of the long profile 2 from one transport disc 3a, 3c to the adjacent transport disc 3b, 3d. The recesses 6a, 6b, 6c, 6d of the transport discs 3a, 3b, 3c, 3d are not circular, but adapted to the square cross-section of the long profiles 2, so that the long profiles 2 can be transported in the recesses 6a, 6b, 6c, 6d in a rotationally fixed manner relative to the respective transport disc 3a, 3b, 3c, 3d.

[0068] The method of Figure 6 makes use of the fact that the long profile axis 12 is transported in a cycloidal motion in the transport direction T, and the height H of the roller brush axis 8a is adapted to the movement. The height distance h of the roller brush axis 8a from the long profile axis 12 is variable and selected such that a distance A of the roller brush axis 8a from the lowest point of the recess 6a, 6b, 6c, 6d, in which the long profile 2 is currently being transported, remains constant.

[0069] Of course, other spacing profiles are also conceivable.

[0070] In particular, it can be provided that the roller brush axis 8a, 8b is changed not only in its vertical distance h, but also in its longitudinal distance I. This takes into account, for example, the fact that the roller brush 7a, 7b wears out over time and brushes become shorter, so that the roller brush axis 8a, 8b is moved closer to the respective row of transport discs 5a, 5b over time, so that the distance of the roller brush 7a, 7b to the deburring long profile ends 2a remains the same. The distance profile can be broken down into a vertical distance profile and a longitudinal distance profile; parameters are specified and parameter values ​​are determined from which the control device calculates control values ​​of the control device and the distance profile is determined. These parameters can be, for example, the angular position of the transport discs 3a, 3b, 3c, 3d.From the angular position of the transport discs 3a, 3b, 3c, 3d, the position of a center point of the recess 6a, 6b, 6c, 6d in which a long profile 2 is to be transported is determined, and the height of the center point of the recess 6a, 6b, 6c, 6d, which corresponds to the position of the central axis 12 of the long profile 2, is equated with the height of both roller brush axes 8a, 8b. This corresponds to the process in Figure 5; alternatively, each angular position of a transport disc 3a, 3b, 3c, 3d can be assigned the position of a lowest point of a recess 6a, 6b, 6c, 6d that is currently transporting one of the long profiles 2. The distance A is added to the lower position, and the determined position corresponds to the height of the two roller brush axes 8a, 8b. Of course, various other methods are also conceivable that make it possible to determine a distance profile from the angular position and other parameters.
