Description

Technical Field

[0001] This invention relates to an apparatus system for internal treatment of pipes, the apparatus system comprising at least one media guiding device, a drive unit, a cartridge unit, and a spool unit with at least one reel, wherein the media guiding device is arranged on the spool in a rewindable and / or unwindable manner and is configured at one end to receive a tool for internal treatment of the pipe. The invention also relates to an apparatus for internal treatment of pipes. Background Technology

[0002] This type of equipment system and device is known from existing technology and is used in the field of tube processing. Especially in cut-and-cover tube processing using milling or laser cutting, pretreatment of the hard-to-reach internal areas of the tube is often required. A common internal treatment method here is to wet the inner wall of the tube with a separating agent. This agent serves to protect the tube and prevent the adhesion of slag and dirt. This improves the quality of the tube processing.

[0003] One feasible method for wetting the inner wall of the tube with a separating agent is to manually introduce it into the nozzle system. However, this method is time-consuming and costly. Therefore, equipment for motorized nozzle introduction systems is often used.

[0004] A mobile device for internal treatment of tubes, particularly refrigerant tubes in steam condensers and heat exchangers, is known from DE 10 2010 047 589 A1. This device has an application hose wound around a driven drum. The application hose is unwound and inserted into the tube to be treated by a separate actuator that is permanently in a driven position. In the event of equipment failure or failure of the driven drum or actuator, the application hose can only be laboriously wound back onto the drum against the resulting actuator resistance torque. Furthermore, the device must be oriented to the corresponding initial position each time internal treatment is performed, followed by manual operation. These are not sufficient prerequisites for automating the internal treatment of tubes. Summary of the Invention

[0005] The purpose of this invention is to provide a reliable, inexpensive and automated equipment system, as well as a device for reliable, inexpensive and automated internal processing of pipes.

[0006] According to the invention, this objective is achieved by the equipment system according to the invention and the apparatus according to the invention for internal processing of pipes.

[0007] In other words, this objective is achieved by an equipment system for internal processing of pipes, the equipment system having at least one media guiding device, a drive unit, a cartridge unit, and a reel unit with at least one reel.

[0008] The media guide can be arranged on a roll in a rewindable and / or unwindable manner. In other words, the media guide is configured to be flexible and / or bendable at least about an axis. Preferably, the media guide is configured as a multi-piece, especially a plurality of pieces, wherein these sub-elements are arranged close to each other in a mutually movable manner. This can improve rewindability and / or unwindability.

[0009] The media guiding device is configured at one end to receive a tool for internal processing of the tube. Preferably, the media guiding device has an adapter, especially a quick-lock adapter, to easily receive and replace various different tools. This allows for greater flexibility in the use of the media guiding device.

[0010] The media guiding device is configured at the other end for mounting on a drum. Preferably, the media guiding device has fastening devices, particularly threaded connections, for permanent fastening to the drum. This ensures a particularly reliable mounting of the media guiding device on the drum.

[0011] The drive unit has a driver, especially just one driver. The driver is configured, especially only configured, for winding and / or unwinding the media guide. In other words, the driver causes a translational relative movement of the media guide relative to the driver. This enables reliable control of the driver's process. Preferably, the driver is configured as an electric motor. Thus, the unwinding and / or winding of the media guide can be achieved particularly efficiently and economically.

[0012] Furthermore, the actuator is configured to move from a free-running position to a driving position for the medium guiding device. In other words, the actuator and / or drive unit is configured to be able to change orientation, such as being movable, pivotable, rotatable, flip-up, and / or connectable. Preferably, the drive unit and / or actuator is configured to move on at least one track. This enables rapid motion control that is technically easy to implement.

[0013] More preferably, the drive unit and / or driver are capable of moving on two or more tracks. This allows for particularly flexible movement of the drive unit and / or driver.

[0014] In a particularly preferred manner, the drive unit and / or driver are configured to move via three mutually orthogonally arranged tracks. This allows for reliable motion through a conventional machine coordinate system.

[0015] In the context of the invention, the driving position is the arrangement of the driver relative to the media guiding device, which causes the media guiding device to be indirectly and / or directly driven by the driver. Direct driving can be achieved through direct contact between the driver and the media guiding device. Indirect driving can be achieved through an intermediate element that transmits the drive, such as by using gears, rollers, etc.

[0016] In the sense of the invention, the free-running position is the positioning of the driver relative to the media guiding device, in which the media guiding device is not indirectly or directly driven by the driver.

[0017] The cartridge unit has at least one drive cartridge. According to the invention, the drive cartridge is configured to guide the media guide device by means of a cartridge guide device. In other words, the cartridge guide device restricts the possible translational and / or rotational directions of movement of the media guide device. Preferably, the cartridge guide device restricts the direction of movement to a translational direction, particularly exactly one translational direction. Particularly preferably, the cartridge guide device defines the movement along the processing axis of the equipment system by restricting the direction of movement. This allows the media guide device to unwind and / or rewind only along the processing axis, which further has a favorable effect on process reliability and automation.

[0018] In a preferred embodiment, the cartridge guide device has a drivable roller guide. In this case, the driver can be configured to move from a free-running position to a driving position for indirectly driving the drivable roller guide device. This ensures particularly reliable connection of the driver.

[0019] The drivable roller guide has at least one roller. Preferably, the drivable roller guide has two or more rollers. The drivable roller guide can be form-locked and / or force-locked against a media guide. Form-locking contact can be achieved, for example, by toothed engagement of the roller into the media guide. Force-locking contact can be achieved, for example, by means of a friction pair between the roller and the media guide. Therefore, the roller guide can be fitted to the media guide with particular flexibility.

[0020] Particularly preferably, at least one roller is configured as a drive roller and / or at least one roller is configured as a support roller. In this case, the drive roller and the support roller preferably rest against opposite sides of the media guiding device. The support roller is configured to operate freely, while the drive roller is configured to perform drive transmission from the driver to the media guiding device. Thus, guiding the media guiding device can be performed with particularly low friction, and also provides efficient engagement capability for the driver.

[0021] A preferred embodiment of the equipment system is that the drive unit has a friction wheel. The friction wheel is preferably directly mounted or fastened to the drive unit and follows the movement of the drive unit. In other words, the friction wheel is configured to move to a drive position for winding and / or unwinding the media guide device and / or drivable roller guide device. This allows for more efficient drive transmission to the media guide device.

[0022] A further preferred embodiment of the equipment system is that the box guiding device has a guide sleeve. The guide sleeve is part of the box guiding device and is preferably located downstream of the driveable roller guiding device in the direction of the tube to be processed along the processing axis. This further improves the guidance performed by driving the box.

[0023] The guide sleeve can be configured to accommodate a guide rod disposed on a media guiding device. Preferably, the guide sleeve has a through recess for this purpose. More preferably, the guide sleeve has a guide stop for the guide rod within the through recess along the direction of movement of the media guiding device, especially along the winding direction of the media guiding device. This allows the final position of the media guiding device or the initial position of the media guiding device to be provided using particularly simple and inexpensive devices.

[0024] Alternatively or additionally, the position of the medium guiding device and / or guide rod within the guide sleeve can be determined by a proximity switch, particularly in the form of a non-contact end detector. This allows for particularly simple recalibration of the final or initial position of the medium guiding device. Preferably, the proximity switch is arranged in a recess in the wall of the guide sleeve. More preferably, in this case, the medium guiding device has an marking portion. The marking portion can, for example, be constructed as a recess and / or a raised portion. This allows for monitoring of the proximity switch's signal in relation to a recurring pattern during proximity identification, thereby enabling particularly protective identification of the medium guiding device's position via the proximity switch.

[0025] More preferably, the guide sleeve is constructed in a multi-piece, particularly two-piece, configuration. This improves accessibility to the internal space of the guide sleeve and ease of maintenance when arranging the media guiding device.

[0026] In another preferred embodiment of the equipment system, the cartridge unit has a cartridge holder. In this case, the cartridge holder can be configured as a carrier for the drive cartridge. The cartridge holder is preferably configured for detachably arranging at least one drive cartridge, and more particularly each drive cartridge. By detachably arranging the drive cartridges, the drive cartridges located on the cartridge holder can be replaced particularly easily.

[0027] A preferred improvement to the equipment system is that the drive box, detachably arranged on the box holder, is secured by a locking device. This reliably prevents the drive box from detaching at any point in time. More preferably, the locking device is pneumatically configured. This allows for automated control of the locking device via a pneumatic system in a particularly reliable manner. Preferably, the pneumatic locking device has a pneumatic locking cylinder. The locking device can therefore be controlled particularly robustly and with rapid response.

[0028] In a particular extension of the equipment system, it is proposed that the drive unit has a box-connecting device for mechanically coupling the at least one drive box. For example, the connecting device can be constructed in the form of a clamp. Preferably, the drive box has a receiving section constructed opposite to the box-connecting device, in particular a receiving tongue. Thus, the coupling of the drive unit and the drive box can be performed particularly quickly and reliably. With the aid of the box-connecting device, the drive unit can be temporarily and / or permanently secured to the drive box. This is particularly advantageous when the drive box is released from the box holder in this case. Thus, the drive box can move together with the drive unit, especially along the processing axis. Therefore, in cases where internal processing needs to be performed on short pipes, the drive box can be guided by the drive unit up to the pipe end, thereby enabling the targeted introduction of the media guiding device with particular reliability.

[0029] A preferred embodiment of the equipment system proposes that the cartridge unit has at least one additional drive cartridge. The additional drive cartridge can be constructed identically to the at least one drive cartridge. This reduces the manufacturing cost of the drive cartridge. Alternatively, the additional drive cartridge, particularly the cartridge guide device, can have a different construction than the at least one drive cartridge. This is advantageous in matching the additional drive cartridge to another media guide device to be guided. The driver is preferably configured to drive the other media guide device of the additional drive cartridge. In this case, the driver is configured to move from a free-running position, particularly the same free-running position, to a driving position for the other media guide device. This allows the same driver to be particularly advantageously used to drive multiple media guide devices.

[0030] Preferably, the extension of the equipment system involves arranging the at least one additional drive box parallel to the at least one drive box. Preferably, these drive boxes are arranged laterally, and especially orthogonally, relative to the processing axis. Thus, these drive boxes can be advantageously arranged to have the same distance from the tube to be processed.

[0031] All drive boxes are preferably arranged detachably on the box holder. More preferably, each drive box can be secured to the box holder by means of an individual locking device. This allows for particularly flexible access to each drive box.

[0032] In a preferred embodiment of the equipment system, the media guiding device is constructed in the form of a towing chain and / or a hose and has at least one, especially at least two, and particularly preferably at least three media lines. Preferably, the at least one media line, especially each media line, is guided within the media guiding device. Thus, the media lines guided within the media guiding device can be effectively protected from external influences, mechanical stress, and / or damage.

[0033] More preferably, the media line is guided from the drum to the tool entirely within the media guiding device. This can more effectively prevent damage.

[0034] The medium circuit is understood herein and hereinafter, for example, as a separator circuit, a compressed air circuit, and / or an electrical circuit, wherein the medium is present accordingly in the form of a separator, compressed air, and / or electricity.

[0035] The task is also accomplished by an apparatus for internal processing of tubes, the apparatus having the aforementioned equipment system and a tube receiving device for receiving the tube to be processed, wherein the equipment system is configured for winding and / or unwinding media guiding devices and for guiding media guiding devices or tools into the tube to be processed.

[0036] Preferably, the equipment for internal treatment of pipes has a uniform machine platform on which the equipment system and / or pipe receiving device are aligned and fastened. This ensures particularly accurate and rapid treatment of the pipes.

[0037] More preferably, the equipment for internal treatment of the pipe is configured to be arranged on a pipe processing machine. Alternatively, it may be proposed that the equipment for internal treatment of the pipe be configured on the pipe processing machine. This allows the internal treatment of the pipe to be carried out particularly advantageously in a process step prior to pipe processing.

[0038] In a particularly preferred extension of the equipment, the drive unit is arranged on the measuring slide of the tube processing machine. This allows the equipment system to be manufactured particularly inexpensively and the process to be reliably integrated into the tube processing machine.

[0039] Other advantages of the invention become apparent from the specification and drawings. Similarly, the features described above and further to be set forth can be used individually or in any suitable combination according to the invention. The illustrated and described embodiments should not be construed as an exhaustive enumeration, but rather as exemplary features for the purpose of explaining the invention.

[0045] Figure 6 It shows Figures 3 to 5 Rear view of the arrangement of the drive unit and the box unit. Detailed Implementation

[0046] Figure 1 A section of an apparatus 10 for internal processing of a tube 12 is shown. The apparatus 10 has an assembly system 14 and a tube receiving device (not shown) for receiving the tube 12 to be processed. The tube receiving device is configured to orient or position the tube 12 such that its central axis 16 extends substantially along the processing axis 18 of the assembly system 14. The assembly system 14 may have multiple processing axes 18. In this case, the tube receiving device aligns the central axis 16 substantially concentrically with one of the processing axes 18. Preferably, the processing axis 18 is specified in this case. "Substantially concentrically aligned" is understood to mean that, with this alignment, the assembly system 14 can perform internal processing within the tube 12. Small deviations between the central axis 16 and the processing axis 18 can be compensated, for example, by the assembly system 14.

[0047] The equipment 10 has a machine frame 20 erected on and / or fastened to a machine base (not shown). The machine frame 20 is preferably constructed with a uniform machine platform for arranging the equipment system 14 and the pipe receiving device. In other words, the various components to be arranged on the machine frame 20 can be aligned with each other relative to this uniform machine platform. This allows for particularly easy assembly and disassembly of the equipment 10 while maintaining the lowest possible tolerances.

[0048] The equipment system 14 includes a reel unit 22, a drive unit 24, a cartridge unit 26, and a media guiding device 28.

[0049] The drum unit 22 has a support structure 30, which is fastened to the machine frame 20 by means of a threaded connection. The support structure 30 is configured to accommodate the various components of the drum unit 22. Thus, the drum unit 22 can be manufactured in a modular manner with particular advantage and can be installed on the equipment 10 particularly quickly and easily.

[0050] In the illustrated embodiment of device 10, cassette unit 26 is secured to machine frame 20 by means of retaining flange 32. This is a particularly robust and simple arrangement on machine frame 20. It can also be proposed that cassette unit 26 is pivotally secured to machine frame 20. Thus, cassette unit 26 can pivot horizontally, away from processing axis 18. This facilitates access to areas of device 10 blocked by cassette unit 26, for example, during cleaning and / or maintenance work. Further advantageously, by pivoting cassette unit 26 out without removing device 10, additional space can be provided, for example, in the case of extra-long tubes 12. Therefore, manual internal handling of tubes 12 can still be achieved, for example, by manually operated media guide device 28.

[0051] In the illustrated embodiment, the drive unit 24 is movably arranged on the device 10 by means of a slide 36 guided on a track 34. In the illustrated embodiment, the track 34 is configured to guide the slide 36 parallel to the tube axis 16 or the machining axis 18. In other words, the slide 36 can only move parallel to the machining axis 18.

[0052] The media guiding device 28, except for the end section 40, is arranged primarily on the spool 38 of the spool unit 22 in a winding manner. The end section 40 is arranged at the drive box 42 of the box unit 26. Therefore, the end section 40 has a length equivalent to the distance between the spool unit 22 or the spool 38 and the box unit 26 or the drive box 42.

[0053] The medium guiding device 28 has a tool 44 for internal processing of the tube 12 at the end facing the tube 12. The tool 44 has, for example, a centering device 46 for centering the tool 44 inside the tube 12, a nozzle for discharging fluid (especially a separating agent and / or compressed air), a probe for probing the inner wall of the tube, and / or a temperature control unit for adjusting the temperature of the inner wall of the tube.

[0054] The basic process of the method for internally processing tube 12 via device 10 will be briefly described below. According to... Figure 1The device 10 is in its initial position, with the medium guide device 28 wound onto the spool unit 22. First, the tube 12 is oriented in a tube receiving device (not shown) such that the tube's central axis 16 is concentric with the processing axis 18. Then, the medium guide device 28 is unwound from the spool unit 22 by the drive unit 24. During the unwinding of the medium guide device 28, it is guided into the tube 12 by the cassette unit 26 until the end of the tube 12 facing away from the equipment system 14 (not shown). Preferably, the tool 44 then begins internal processing of the tube 12, wherein, in the current case, a medium (e.g., compressed air, a separating agent, or current) is fed to the tool 44 via the medium guide device 28. Simultaneously or staggered in time, the drive unit 24 winds the medium guide device 28 onto the spool unit 22. The internal processing of the tube 12 and / or the winding of the medium guide device 28 can be temporarily interrupted and resumed. Therefore, the intensity and / or manner of internal processing can be varied depending on the position of the tool 44 within the tube 12. Internal processing of the tube 12 preferably ends when the tool 44 reaches the tube end 48 facing the device 10. The winding process of the media guide 28 is completed when it reaches its initial position at the cartridge unit 26.

[0055] The apparatus 10 for internal treatment of the tube 12 can be configured to be arranged on and / or constructed as part of a tube processing machine (not shown). Such a tube processing machine can be, for example, a tube cutting machine, particularly a milling machine and / or a laser cutting machine. Advantageously, the apparatus 10 is connected upstream of the tube processing machine in the process flow. This enables internal treatment of the tube 12, particularly wetting the inner wall of the tube with a separating agent, directly before tube processing is performed on the tube processing machine. This allows for tube processing to be performed particularly quickly and cost-effectively.

[0056] Figure 2 The diagram is shown separately from device 10. Figure 1 The equipment system 14 of the device 10, which does not include the load-bearing structure 30 of the drum unit 22 (see...). Figure 1 ).

[0057] The reel unit 22 has two parallel and concentrically arranged reels 38. Each of these reels 38 is configured to arrange a media guide 28 in a rewindable and unwindable manner. In the illustrated embodiment, the media guide 28 is arranged on only one reel 38.

[0058] To guide the media guide device 28, the drum unit 22 correspondingly has a drum-side roller guide device 50, which has two rotatable rollers. The drum-side roller guide device 50 is configured to guide the media guide device 28 along the machining axis 18 and prevent the media guide device 28 from moving laterally to the machining axis 18.

[0059] The drum unit 22 has two reset devices 52 that generate a reset torque 54 on their respective drums 38 to support the drive unit 24 during winding of their respective media guides 28. The reset devices 52 each have a force element 56 (in the form of a pneumatic cylinder) and a reshaping element 58 (or force transmission device) (in the form of a cable traction element).

[0060] Each pneumatic cylinder can be connected to an adjustable pneumatic system (not shown) via compressed air interfaces 60, 62. By applying appropriate pressure to the compressed air interfaces 60, 62, a piston (not visible) guided within the pneumatic cylinder can be deflected by a piston rod 64 guided on the piston.

[0061] When a positive pressure difference exists between one of the compressed air ports 60 and the corresponding compressed air port 62 in the same pneumatic cylinder, the piston rod 64 deflects upward in the vertical direction. The pneumatic cylinder, or force element 56, expands. Similarly, if a negative pressure drop exists between the pressure ports 60 and 62 in the same pneumatic cylinder, the force element 56 contracts, or the piston rod 64 moves downward in the vertical direction.

[0062] Preferably, the reset device 52 only generates a reset torque 54 on the drum 38 during the winding of the media guide 28 onto the drum 38. Conversely, it can be argued that the reset device 52 operates freely during the unwinding of the media guide 28. In other words, although the reset device 52 is arranged on the drum 38, it does not transmit a significant torque that reacts to the unwinding motion to the drum 38. According to the illustrated embodiment, this can be achieved by correspondingly applying pressure to the pressure ports 60, 62 during the unwinding of the media guide 28. Advantageously, the drive unit 24 can thus be designed substantially to overcome the frictional forces present on the media guide 28. This particularly advantageously affects manufacturing and operating costs.

[0063] According to the illustrated embodiment, the media guiding device 28 is configured as a drag chain. Alternatively, the media guiding device 28 may be configured as a flexible hose. The media guiding device 28 is configured to guide at least one media line (not shown). The media guiding device 28 has higher guiding performance and higher mechanical robustness relative to the at least one media line. This enables the reliable introduction of the media guiding device 28 into the tube 12 to be processed (see...). Figure 1 Furthermore, the dielectric line can be effectively protected from external influences, mechanical stress, and / or damage by means of the dielectric guide device 28. Preferably, the at least one dielectric line is arranged within the dielectric guide device 28. Particularly preferably, the dielectric guide device 28 completely surrounds the at least one dielectric line. Thus, the dielectric guide device 28 can provide particularly effective protection.

[0064] The media guiding device 28 can advantageously guide two or more media lines. This allows for more efficient use of the media guiding device 28 without requiring significant additional design costs.

[0065] The media line can be loosely arranged within the media guiding device 28. The media line can be, for example, a separating agent line, a compressed air line, and / or an electrical line. The media line is guided within the media guiding device 28 to the tool 44. In the case of the tool 44 used for discharging separating agent, the media line is implemented as a separating agent line and flows into one or more nozzles of the tool 44.

[0066] Figure 3 With equipment system 14 (see Figure 1 and Figure 2 The separate diagram shows Figure 1 and Figure 2 The drive unit 24 and the box unit 26.

[0067] Cartridge unit 26 has two drive cartridges 42 arranged parallel to each other. According to the illustrated embodiment, these drive cartridges 42 are constructed identically. A media guiding device 28 is arranged on each drive cartridge 42. Each media guiding device 28 is disposed at one end on the reel 38 (see...). Figure 1 and Figure 2 At the other end is a tool 44, which is adapted to handle pipes 12 with different inner diameters (see...). Figure 1 (This will be processed internally.)

[0068] Each drive box 42 has a box guide 66 configured to guide its respective media guide 28. In the illustrated case, each box guide 66 has a drivable roller guide 68 and a guide sleeve 70.

[0069] The drivable roller guide 68 can be configured to guide the media guide 28 in a form-locking and / or force-locking manner. In the present case, the drivable roller guide 68 is configured for form-locking guidance via a support roller 72 and a drive roller 74. The drive roller 74 is configured as a friction wheel and has a rubber-elastic friction lining to improve the force-locking connection with the media guide 28. Driven by the drive roller 74, the media guide 28 moves, or is unwound from or wound onto the spool 38.

[0070] Support roller 72 and drive roller 74 are arranged vertically opposite each other on media guide device 28 (for clarity, the construction of roller guide device 68 on one drive box 42 is shown exemplary only in the drawings). Support roller 72 surrounds media guide device 28 and has a working surface that matches media guide device 28. Thus, media guide device 28 can be supported in the vertically downward direction and in two lateral directions. In the vertically upward direction, media guide device 28 is supported by the abutment of drive roller 74. In other words, the introduction of media guide device 28 can be achieved only in the processing direction 18 or can be achieved by temporarily removing support roller 72 or drive roller 74. This reliably prevents media guide device 28 from jumping out of box guide device 66.

[0071] The guide sleeve 70 is arranged in the extension of the drivable roller guide 68 and forms the end position of the media guide 28. For this purpose, the guide sleeve 70 may be configured with an end stop that prevents the media guide 28 from being further wound onto the spool 38. In other words, the end stop can establish the initial position of the media guide 28. Preferably, in this case, the end stop has a final position switch that switches to electrical contact when the media guide 28 abuts against the end stop.

[0072] Alternatively and / or additionally, the drive box 42 of the box unit 26 (such as...) Figure 3 (As shown) Each has a proximity switch 76 in the form of a non-contact end detector for identifying the position of the media guide device 28 within the guide sleeve 70. Preferably, the proximity switch 76 is arranged in a wall recess 78 of the guide sleeve 70 (for clarity, only one proximity switch 76 and the two wall recesses 78 of the single drive housing 42 are provided with corresponding reference numerals). Preferably, the media guide device 28 has an invisible marking portion for defensively identifying the position of the media guide device 28 by means of the proximity switch 76. With the above configuration, the position of the media guide device 28 in its initial position can be reliably supplemented with calibration and / or adjusted according to changes in the tool 44 and / or the media guide device 28.

[0073] The guide sleeve 70 can be constructed in a multi-piece, especially a two-piece, configuration to ensure accessibility to the internal space of the guide sleeve 70.

[0074] According to the embodiment shown, the guide sleeve 70 is configured to receive the guide rod 80 of the media guiding device 28. The guide rod 80 allows for particularly reliable determination of position identification via the proximity switch 76. The guide rod 80 has a cross-section constructed opposite to the rectangular cross-section of the guide sleeve 70. This allows for reliable determination of the initial position regarding rotational position about the machining axis. In an alternative embodiment, the guide sleeve may have a circular or elliptical cross-section. If the rotational position of the media guiding device 28 is relative to the tube 12 (see...) Figure 1 If the internal processing of the tube is less important, this would be advantageous in terms of manufacturing costs. This could be, for example, by using a rotationally symmetrical tool 44 to wet the inner wall of the tube 12 with a separating agent.

[0075] The guide rod 80 is arranged or secured to the media guiding device 28 and configured to receive the tool 44. Preferably, the guide rod 80 is configured to receive different tools 44 by means of a quick-lock.

[0076] According to the invention, the drive unit 24 is in a drive position for the media guiding device 28. According to the illustrated embodiment, the friction wheel 82 of the drive unit 24 is in force-locked contact with the drive roller 74 of one of the drive boxes 42 of the box unit 26. The friction wheel 82 is driven by the driver 84 (in the form of an electric motor), causing the media guiding device 28 to move indirectly, or to unwind and / or rewind onto the spool 38. According to the embodiment, the friction wheel 82 has a friction lining that is, in particular, rubber-elastic.

[0077] According to the invention, the drive unit 24 can move from a free-running position to a driven position. According to the illustrated embodiment, the friction wheel 82 and the drive unit 84 can jointly move via two adjusting tracks 86 to force-locking contact with the housing unit 26 or the drive roller 74 (the adjusting tracks 86, which are shown in dashed lines under obstruction). The adjusting tracks 86 are preferably arranged in an orthogonal plane to the machining axis 18. More preferably, the adjusting tracks 86 are arranged orthogonally to each other. Particularly preferably, the adjusting tracks 86 are configured as a vertically oriented vertical adjusting track and a horizontally oriented horizontal adjusting track. Thus, the drive unit 84 and the friction wheel 82 can move from the driven position and to the driven position particularly efficiently and reliably.

[0078] In the illustrated embodiment, the drive unit 24 is configured to be arranged on the slide 36 and thus movable on the track 34 of the device 10 along an axis parallel to the machining axis 18 (see [link]). Figure 1This eliminates the need for the corresponding adjustment track 86. Alternatively or additionally, the drive unit 24 may have another adjustment track 86 in a third spatial direction. Preferably, the other adjustment track 86 is arranged orthogonally to the other two adjustment tracks 86 or parallel to the processing axis 18. Thus, the drive unit 24 can move to a free-running position with particular flexibility according to the construction of the box unit 26.

[0079] According to the embodiment, the drive unit 24 has a position sensor 88 for determining the position of the drive unit 24 relative to the medium guiding device 28. The position sensor 88 is configured as a non-contact end detector and is arranged in a wall recess 78 of the guide sleeve 70. This allows the drive position and / or free-running position of the drive unit 24 to be reliably determined through a specific process.

[0080] The drive unit 24 has a box coupling device 90 for separately mechanically coupling the drive box 42. According to the illustrated embodiment, the box coupling device 90 has a parallel gripper 92, which is movable along the coupling axis 96 by means of a coupling actuator 94 (in the form of a pneumatic cylinder). The coupling axis 96 is preferably constructed laterally relative to the machining axis 18, particularly orthogonally in the top view of the equipment system 14, or along the arrangement direction of the drive box 42. Figure 3 In the case shown in the diagram, the parallel gripper 92 is engaged with the receiving tongue 98 of one of the drive boxes 42.

[0081] Figure 4 The box unit 26 and drive unit 24 are shown in either a free-operating position or in a non-connected arrangement. In the following description, to explain the functional principles, the various steps for connecting the drive unit 24 to one of the drive boxes 42 are described.

[0082] Based on the foregoing Figure 3 In the connection arrangement (where drive unit 24 is connected to one of drive boxes 42), the drive 84 and friction wheel 82 first move from the driven position to the free-running position by movement along one of the adjusting tracks 86. Simultaneously, position sensor 88 rises from the wall recess 78 of guide sleeve 70. Subsequently, friction wheel 82 does not make any driven contact with any of the drive rollers 74 of drive box 42 or with media guiding device 28.

[0083] Subsequently, the parallel gripper 92 is disengaged from the receiving tongue 98 of the drive box 42 by moving along the connecting axis 96. For process reliability reasons, disengagement occurs before the drive unit 24 moves to the free-running position. However, alternatively, it is conceivable that the disengagement of the parallel gripper 92 and the receiving tongue 98 is performed beforehand or simultaneously with the movement toward the free-running position. Afterward, the drive unit 24 is released from the drive box 42 or the box unit 26.

[0084] In the illustrated embodiment, each drive box 42 has two centering elements 100 (only the centering pins are visible in the illustrations) (here in the form of a centering ball and a centering pin). The two centering elements 100 of each drive box 42 engage with a centering recess 102 of the drive unit 24, which is constructed oppositely, during connection. To release the contact between the centering elements 100 and the centering recess 102, the drive unit 24 (as shown) moves along the machining axis 18. In the illustrated embodiment, this can be achieved by means of the movement of the slide 36 (see...). Figure 1 ).

[0085] Figure 5 A drive unit 24 is shown arranged in connection with either the housing unit 26 or another drive housing 42. Based on... Figure 4 In the position shown, the parallel gripper 92 moves along the coupling axis 96 toward the other drive box 42. Subsequently or simultaneously, the drive unit 24 (e.g., by means of the slide 36, see...) moves... Figure 1 It moves along the processing axis 18 toward the box unit 26.

[0086] When it reaches the drive box 42, the drive unit 24 uses the centering element 100 (not visible, see) to center the drive unit 42. Figure 4 ) is embedded in the centering recess 102 and is oriented with respect to its position relative to the drive box 42. Figure 5 Only the centering recess 102 is visible in the middle; see also Figure 4 ).

[0087] After reaching a position above the drive box 42 (where position sensor 88 can be used to determine this position), the parallel gripper 92 moves along the coupling axis 96 to engage with the receiving tongue 98. The drive unit 24 is now in a state of connection with the drive box 42.

[0088] Subsequently, by lowering the driver 84 and friction wheel 82 along the adjustment track 86 onto the drive roller 74 of the drive box 42, the drive unit 24 is moved to the drive position for the medium guide device 28.

[0089] According to the illustrated embodiment, the cartridge unit 26 also has a cartridge retainer 104 for releasably arranging the drive cartridge 42. This allows for particularly quick and easy replacement of the drive cartridge 42. According to one embodiment, the cartridge retainer 104 may have a pneumatic locking device 106 configured to automatically release the drive cartridge 42 from the cartridge retainer 104. As shown, the locking device 106 is configured as an arcuate member 110 pivotable about a pivot point 108, wherein the arcuate member 110 has a locking protrusion 112. By means of a locking cylinder 114 (here, a compressed air cylinder), the arcuate member 110 is pressed toward the drive cartridge 42, and thus the locking protrusion 112 is pressed into a locking recess (not visible) of the guide sleeve 70. To release the drive cartridge 42, the locking cylinder 114 retracts, thereby causing the arcuate member 110 to pivot away from the drive cartridge 42. The locking protrusion 112 therefore does not engage with the locking recess, and the drive box 42 can be released from the box holder 104 along the direction of the machining axis 18.

[0090] In this advantageous combination of features, the drive box 42, connected to the drive unit 24, can be moved along the machining axis 18 by the drive unit 24 via the drive unit 24 by releasing the pneumatic locking device 106. Thus, the equipment system 14 ( Figure 1 and Figure 2 ) directed to pipes 12 of different lengths ( Figure 1 This is to prevent the medium guide device 28 from sagging or from failing to reach the pipe 12 when the distance between the equipment system 14 and the pipe to be processed is too large.

[0091] Figure 5 The rear view shows the box unit 26 and drive unit 24 from the previous figure to better explain the locking device 106.

[0092] The box unit 26 is secured to the retaining flange 32 by means of the box retainer 104 and the locking device 106. The bow-shaped member 110 can pivot about the pivot point 108 relative to the box retainer 104 by expanding or contracting the locking cylinder 114.

[0093] In the present case, each drive box 42 has a pneumatic locking device 106 for being releasably arranged on the box holder 104.

[0094] Looking at all the figures, the present invention relates to an apparatus system 14 for internal processing of a tube 12, wherein a drive unit 24 unwinds a media guide 28 guided by a drive cartridge 42 from a spool 38 and guides it into the tube 12. Furthermore, the drive unit 24 is configured to rewind the media guide 28 onto the spool 38. According to the invention, the drive unit 24 is movable from a free-running position to a driven position for rewinding and / or unwinding the media guide 28. The invention also relates to an apparatus 10 having such an apparatus system 14 for internal processing of a tube 12.
