Description
[0001] P220922-33 / PCT Drilling device 1 Drilling device for a profile sealing strip, application head, system for applying a profile sealing strip to a door or a body of a motor vehicle and method for producing a bore The invention relates to a drilling device for a profile sealing strip and a method for producing a bore. Furthermore, the invention relates to an application head of a profile sealing application device with the drilling device according to the invention and a system for applying a profile sealing strip comprising the drilling device. Drilling stations for sealing profiles are already known, wherein the seal for this is already arranged on the respective component and thus the component with the seal does not have to undergo an additional process step.In this process, the holes in the seal are either created on the stationary component by moving the drilling station, or the component with the seal is guided to a stationary drilling station for each hole to be created, where the holes are created accordingly. Alternatively, the openings can also be created by punching, with the openings being created on the profile sealing strip in a separate device by punching, and only then is the profile sealing strip applied. This involves a multitude of handling steps. Furthermore, DE 102016 114 461 A1 discloses a method for producing vent openings in a sealing profile, wherein the vent openings are introduced into the sealing profile using a laser beam.All solutions have in common that they are independent of the application process of the respective profile sealing strip (P220922-33 / PCT drilling device 2), require additional handling steps, and also take up additional processing time. The object of the invention is to provide a drilling device for a profile sealing strip, a method for producing a bore, an application head of a profile sealing application device, and a system for applying a profile sealing strip, each with the drilling device according to the invention as a subassembly, which enables the bores to be produced in the profile sealing strip directly, as needed, and without significant delay in the application process.In the specified application, the invention achieves the creation of a drilling device for a profile sealing strip, wherein a drilling unit is provided and at least one guide device is provided through which the profile sealing strip can be guided in a longitudinal extent, wherein the guide device with the profile sealing strip guided therein or thereby can be rotated relative to the drilling unit about a longitudinal axis of the longitudinal extent of the profile sealing strip and wherein the guide device has a rotation angle positioning device. This allows bores to be drilled directly on the profile sealing strip at different locations, since for this purpose the profile sealing strip can be rotated in the guide device by the rotation angle positioning device itself. Thus, both bores without twisting and bores with twisting are equally conceivable.In addition, the profile sealing strip can be rotated longitudinally around a longitudinal axis, both to the right and to the left, as required. This allows a wide range of profile sealing strips to be achieved. As the profile sealing strip can be guided longitudinally by the guide device, the profile sealing strip can initially be freely conveyed or moved along its longitudinal extent, for example for an application. If drilling is required, the movement or conveyance of the profile sealing strip in the longitudinal extent or longitudinal direction can stop and the profile sealing strip comes to a standstill and is thus immobile in the longitudinal extent or longitudinal direction. The drilling can now be carried out without twisting or with twisting about a longitudinal axis using the rotation angle positioning device.Subsequently, the profile sealing strip is returned to a position for movement or conveyance of the profile sealing strip for application by means of the rotation angle positioning device. A further aspect of the invention relates to an application head of a profile sealing strip application device, wherein the application head comprises a drilling device according to the invention. A third aspect of the invention relates to a system for applying a profile sealing strip to a door or a body of a motor vehicle, wherein the system comprises a drilling device according to the invention and a profile sealing strip application device with an application head for applying the profile sealing strip to the door or a body.A fourth aspect of the invention relates to a method for producing a bore in a profile sealing strip using a drilling device according to the invention, wherein the profile sealing strip, which is moved or stationary in the direction of a longitudinal extension, is rotated from an initial position about a longitudinal axis of the longitudinal extension between 0 degrees and 75 degrees as required into a drilling position and that subsequently, in the drilling position, a drilling unit produces a bore in the profile sealing strip and then the profile sealing strip is rotated or brought back from the drilling position into the initial position as required, wherein when the profile sealing strip is rotated about the longitudinal axis P220922-33 / PCT drilling device 4 of the longitudinal extension of or by 0 degrees, the initial position and the drilling position are the same.If necessary, the profile sealing strip can be rotated from an initial position around a longitudinal axis of the longitudinal extension between 76 degrees and 100 degrees into a drilling position as required. Advantageous embodiments of the various aspects of the invention are presented in the subclaims. Since the guide device comprises at least one guide unit, the profile sealing strip can be guided through the guide device more reliably, stress-free, and at least with minimal deformation. If two or more guide units are used, the guide units are arranged spaced apart from one another, so that the profile sealing strip can be guided between the respective guide units reliably, stress-free, and at least with minimal deformation.By arranging the angle of rotation positioning device in the area of at least one guide unit or, in the case of two or more guide units, between two of the guide units or outside or away from the guide units, the profile sealing strip can be rotated into the respective angle of rotation more reliably, free from stress and at least with little deformation. In addition, the design is simplified. By having the angle of rotation positioning device a guide unit, the design is simplified and, in addition, the profile sealing strip can be rotated into the respective angle of rotation more reliably, free from stress and at least with little deformation. By having the guide unit a roller guide, a contour guide or a support guide, the profile sealing strip can be rotated into the respective angle of rotation more reliably, free from stress and at least with little deformation.It is also intended that at least two of the aforementioned guides, such as the roller guide, the contour guide, and / or the support guide, can also be combined with one another. By having the angle positioning device with friction wheels, a slider crank, a worm gear, or a gear drive, flexible and rapid angle adjustment is facilitated. By being able to drive the angle positioning device by means of a worm gear as a linear drive or as a worm gear drive with a worm and a worm wheel, for example, a spur gear, or by means of a servo motor, reliable and flexible angle adjustment is facilitated. In addition, play in the angle positioning can be minimized by using a worm gear or a worm gear drive, and good repeatability can be achieved. A servo motor is reliable and includes a holding brake or a high holding torque to secure the position.Furthermore, it is conceivable that the rotation angle positioning device can be driven flexibly and quickly by means of a pneumatic cylinder or a stepper motor. A combination of at least two of the aforementioned drives is also conceivable. By arranging the drilling unit in the area of the guide device or in the area of at least one guide unit, or in the case of two or more guide units, between two of the guide units or in the area of the rotation angle positioning device, the bore can be produced more reliably and precisely, since the profile sealing strip in this area is rotated into the respective rotation angle position more reliably and with less stress and at least less deformation, and thus the P220922-33 / PCT drilling device 6 bore can be produced in the required position and at the required angle.The drilling unit can also be arranged in the area of the guide device between one of the guide units and the rotary angle positioning device. By arranging the drilling unit with a main working direction transverse or perpendicular to the longitudinal extension of the profile sealing strip, the hole can be created more easily and precisely at the required position and angle. By having a pneumatic, electric, or electromechanical linear drive as the tool feed, the hole can be created quickly, precisely, and in a controlled manner. By providing an extraction system, a blower, or a collecting tray, chips or other residues generated during drilling into the profile sealing strip can be reliably collected and disposed of. Disturbing residues and contamination in the system area can be avoided.By arranging the drilling device in the area of the profile sealing strip feed and / or before or after a length measurement of the profile sealing strip, a space-saving design is achieved on the application head. In addition, the profile sealing strip can be rotated into the respective rotational angle position in this area reliably and without stress and with little or no influence on the application process. By providing the drilling device in the system for applying a profile sealing strip to a door or a body of a motor vehicle, the P220922-33 / PCT drilling device 7 area of the profile sealing strip feed to the profile sealing application device and / or before or after a length measurement of the profile sealing strip, an optimized design and reliable and stress-free rotational angle positioning of the profile sealing strip is promoted.Because the drilling device in the application head and / or system for applying a profile sealing strip can be moved or moved along a conveying direction parallel to the feed of the profile sealing strip, the hole can be created simultaneously during the application process. This allows the application of the profile sealing strip to proceed with minimal delay.The drilling device according to the invention or the application head according to the invention of a profile seal application device with the drilling device or the system according to the invention for applying a profile seal strip with a drilling device according to the invention and a profile seal application device with an application head according to the invention for applying the profile seal strip or the method according to the invention for producing a bore in a profile seal strip using a drilling device according to the invention can each be used or implemented on systems for a stationary application and / or a mobile application, for example on a robot with at least one arm section arranged on the robot or on another handling device.

A drilling device 7 according to the invention for a profile sealing strip 1 (not shown) is shown in Fig. 1. A drilling unit 2 and at least one guide device 3 are provided here. The profile sealing strip 1 can be guided in a longitudinal extent by the guide device 3.The guide device 3 can be rotated with the profile sealing strip 1 relative to the drilling unit 2 about a longitudinal axis of the longitudinal extent of the profile sealing strip 1. The guide device 3 accordingly has a rotation angle positioning device 4, with which the guided section can be rotated according to the requirements of the position of the bore to be produced. The guide device 3 comprises at least one guide unit 5. If there are two or more guide units 5, the guide units 5 are arranged at a distance from one another, for example, in the conveying direction 14 of the profile sealing strip 1, on both sides of the rotation angle positioning device 4. Accordingly, the rotation angle positioning device 4, as shown in Figures 2, 3 and 7, is arranged in the region between two of the guide units 5.The at least one guide unit 5 or the guide units 5 can also be arranged differently distributed in the conveying direction 14 of the profile sealing strip 1, so that the rotational angle positioning device 4 is arranged outside or away from the guide units 5. If necessary, the rotational angle positioning device 4 P220922-33 / PCT drilling device 9 can have a guide unit 5. As shown in Figures 1, 2, 5a to 5c and 7, the guide unit 5 has a roller guide. The roller guide is also designed as a contour guide with roller guides arranged at 45 degrees, as shown in Figures 1, 2 and 5a, or as a support guide, as shown in Figures 1, 5a and 7. The rotational angle positioning device 4 can be driven by means of a worm gear drive with a worm 8 driven by a servo motor and a worm gear 9 driven via the worm 8.Alternatively, a stepper motor or a servo motor can be used directly. Likewise, the drive can also be formed from a combination of different drives. Furthermore, the drilling unit 2 is arranged in the area of the guide device 3 between the two guide units 5 and in the area between one of the guide units 5 and that of the rotation angle positioning device 4. The drilling unit 2 is arranged with a main working direction perpendicular to the longitudinal extent of the profile sealing strip 1 and has a pneumatic linear drive as the tool feed 11. However, electric or electromechanical linear drives can also be provided as the tool feed 11. Furthermore, an extraction system 10 is provided.The drilling device 7 according to the invention for a profile sealing strip 1 (not shown) according to Figure 2 shows a drilling unit 2 and two guide devices 3, which are arranged upstream and downstream of the rotation angle positioning device 4 in the conveying direction 14 of the profile sealing strip 1 and are connected to the rotation angle positioning device 4. The guide devices 3 each comprise at least one guide unit 5. The drilling unit 2 is arranged between the guide unit 5 of the guide devices 3, which is arranged upstream of the rotation angle positioning device 4 in the conveying direction 14 of the profile sealing strip 1, and the rotation angle positioning device 4. The profile sealing strip 1 (not shown) can be guided in its longitudinal extent by the guide device 3 with the at least one guide unit 5.As already described, the profile sealing strip 1 can be rotated relative to the drilling unit 2 with or by the guide devices 3 and their at least one guide unit 5 about the longitudinal axis of the longitudinal extension of the profile sealing strip 1 in order to produce the bore according to the positional requirements. The guide unit 5 has a roller guide arranged at an angle of 45 degrees as a contour guide. The rotation angle positioning device 4 is, as described above, driven by a worm gear drive with a worm 8 and a worm gear 9. The drilling unit 2 is arranged with a main working direction perpendicular to the longitudinal extension of the profile sealing strip 1 and has a pneumatic linear drive as the tool feed 11. In this example, a suction device 10 is also provided.Figure 3 shows a known application head 6 of a profile seal application device, which according to the invention, however, comprises a drilling device 7, as shown in Figures 1 and 2. The drilling device 7 is arranged in the area of the feed 12 of a profile seal strand 1 and upstream of a length measurement 13 of the profile seal strand 1. The drilling unit 2 is arranged between the guide unit 5 of the guide devices 3, which is arranged upstream of the rotation angle positioning device 4 in the conveying direction 14 of the profile seal strand 1, and the rotation angle positioning device 4. Reference is made to the description of Figures 1 and 2. P220922-33 / PCT Drilling device 11 Figures 4a and 4b each show a drilling unit 2, which The drilling unit 2 with an electronic drive of the drill 15 has, as described above, a pneumatic linear drive as the tool feed 11, which is connected to the drilling device 7.Other drives, as described above, are also conceivable. The feed rate for the tool feed 11 depends on the moving masses and the sensitivity of the profile sealing strand 1. For example, a bore that meets the requirements can be carried out with a feed rate for the tool feed 11 of v = 0.075 m / s. However, higher feed rates can also be provided. Furthermore, the suction extractor 10 is arranged on the drilling unit 2. The suction extractor 10 is guided to the drill 15. For the sake of simplicity, the peripheral suction hose leading away from the suction extractor 10 is not shown. Figures 5a to 5c do not show the drilling device 7 according to the invention for a profile sealing strand 1. The drilling unit 2 with the tool feed 11 and a guide block 18 are arranged on a base plate 16.On or in the guide block 18, as shown in Figures 5a to 5c and 7, the angle positioning device 4 is rotatably mounted, and the guide device 3 with the respective guide unit(s) 5 is arranged on the angle positioning device 4. As described above, the angle positioning device 4 can be driven via a worm wheel 9 and a worm 8. A protective wall 17 covering the drill 15 and the drill 15 is present and arranged with the guide block 18. Since a system comprising the profile seal application device is essentially housed in a cell and cannot be entered during operation, protection against injury only needs to be ensured when the machine is at a standstill. Thus, only the drill 15 needs to be shielded to prevent injury from cutting it. The drilling chips are disposed of via a suction system 10.The worm 8 of the rotation angle positioning device 4, shown in simplified form in Figure 6, is also arranged on the guide block 18 via a mounting plate 19. Figure 7 shows the guide block 18 and the worm wheel 9 of the rotation angle positioning device 4 rotatably mounted therein. A guide device 3 with at least one guide unit 5 is arranged on both sides of the rotation angle positioning device 4 or the worm wheel 9. On the guide device 3 arranged upstream of the rotation angle positioning device 4 in the conveying direction 14, a guide unit 5 is additionally arranged as a support guide. The system according to the invention for applying a profile sealing strip to a door or a body of a motor vehicle provides a drilling device 7 as described above and a profile sealing application device with an application head 6 for applying the profile sealing strip 1 to the door or the body.The drilling device 7 is advantageously arranged, as shown in Figure 3, in the region of the feed 12 of the profile sealing strand 1 to the profile sealing application device before a length measurement 13 of the profile sealing strand 1. The drilling device 7 is advantageously displaceable or movable along a conveying direction 14 parallel to the feed 12 of the profile sealing strand 1. The inventive method for producing a bore P220922-33 / PCT drilling device 13 in a profile sealing strand 1 using a drilling device 7 provides that the profile sealing strand 1, which is moved or stationary in the direction or conveying direction 14 of a longitudinal extent, is rotated from an initial position about a longitudinal axis of the longitudinal extent between 0 degrees and 75 degrees as required into a drilling position. Subsequently, a bore is produced in the drilling position in the profile sealing strand 1 by means of a drilling unit 1.After the bore has been created, the profile sealing strand 1 is rotated or brought back from the bore position to its starting position as required. When the profile sealing strand 1 is rotated around the longitudinal axis of the longitudinal extension of 0 degrees, the starting position and the bore position are the same. The sealing profile as profile sealing strand 1 is stopped in the longitudinal direction or conveying direction 14 at the required point and then the bore position is set as the bore angle via the rotation angle positioning device 4 by rotating the rotation angle positioning device 4. As soon as the desired bore position has been set, the opening is drilled by moving the drilling unit 2 as the drilling tool to its stop in the direction of the profile sealing strand 1. Next, the drilling unit 2 moves to its starting position and subsequently the setting angle is also set back to zero from the bore position.The profile sealing strip 1 can now be conveyed further in the conveying direction 14 until the next drilling position is reached, and the process is repeated. The respective drilling positions or angles of the drilling position can be reached without collision. Advantageously, the drilling device 7 according to the invention or the application head 6 according to the invention of a profile sealing application device with the drilling device 7 can be used on systems with a stationary application or a mobile application on a robot with at least one arm section arranged on the robot or on another P220922-33 / PCT drilling device 14 handling device.Likewise, the system according to the invention for applying a profile sealing strip 1 with a drilling device 7 according to the invention and a profile sealing application device with an application head 6 according to the invention for applying the profile sealing strip 1 as well as the method according to the invention for producing a bore in a profile sealing strip 1 using a drilling device 7 according to the invention can be used in a stationary application and a mobile application.
