Definitions
- the invention relates to a set-up system for a device for treating the inside of a pipe, having at least one media guide, a drive unit, a cassette unit and a drum unit with at least one drum, the media guide being able to be arranged on the drum such that it can be rolled up and/or unrolled and at one end to accommodate a tool designed to treat the inside of the pipe.
- the invention also relates to a device for treating the inside of a pipe.
- Such set-up systems and devices are known from the prior art and are used in the technical field of tube processing.
- a common form of internal treatment is wetting the inner wall of the pipe with a separating agent, which on the one hand serves to protect the pipe and on the other hand prevents slag and dirt from adhering. As a result, the quality of the tube processing can be increased.
- DE 10 2010 047 589 A1 discloses a mobile device for treating the inside of pipes, in particular coolant pipes of steam condensers and heat exchangers, which has an application hose wound up on a driven drum.
- the application hose is unwound by means of a separate drive that is permanently in a drive position and inserted into a pipe to be treated.
- the application hose can only be rolled up onto the drum with difficulty against the drive resistance moments that occur.
- the device must be aligned in a corresponding starting position for each internal treatment and then operated manually. With regard to an automated internal treatment of pipes, these are only insufficient prerequisites.
- the object is achieved by a set-up system for a device for treating the inside of a pipe, having at least one media guide, a drive unit, a cassette unit and a drum unit with at least one drum.
- the media guide can be arranged on the drum such that it can be rolled up and/or unrolled.
- the media guide is designed to be flexible and/or bendable at least about one axis.
- the media guide is preferably designed in multiple parts, in particular in multiple parts, with the partial elements being arranged on one another so that they can move relative to one another. As a result, the ability to be rolled up and/or unrolled can be improved.
- the media guide is designed at one end to accommodate a tool for treating the inside of the pipe.
- the media guide preferably has an adapter, in particular a quick-release adapter, for easy accommodation and interchangeability of a number of different tools. As a result, the media guide can be used even more flexibly.
- the other end of the media guide is designed for placement on the drum.
- the media guide preferably has a fastening means, in particular a screw connection, for permanent fastening to the drum. This ensures a particularly secure arrangement of the media guide on the drum.
- the drive unit has, in particular precisely, a drive.
- the drive is designed, in particular only, for rolling up and/or unrolling the media guide.
- the media guide is set into a translational movement relative to the drive by the drive. This enables process-reliable control of the drive.
- the drive is preferably designed as an electric motor. As a result, the media guide can be unrolled and/or rolled up particularly effectively and economically.
- the drive is designed to be movable from a free-running position into a drive position with the media guide.
- the drive and/or the drive unit can be locally changed, e.g. pushed, pivoted, rotated, tilted etc. and/or designed to be coupled.
- the drive unit and/or the drive is designed to be movable on at least one rail.
- the drive unit and/or the drive can be moved on two or more rails.
- the drive unit and/or the drive can be moved in a particularly flexible manner.
- the drive unit and/or the drive is designed to be movable via three rails arranged orthogonally to one another. This allows process-reliable movement using conventional machine coordinate systems.
- a drive position is an arrangement of the drive for the media guide, which causes the media guide to be driven directly and/or indirectly by the drive.
- Direct driving can take place through direct contact between the drive and the media guide.
- Direct driving can take place through the interposition of drive-transmitting elements, for example through the use of gears, rollers, etc.
- a free-running position is a positioning of the drive for the media guide, with which neither an indirect nor a direct driving of the media guide by the drive is effected.
- the cassette unit has at least one drive cassette.
- the drive cassette is designed by means of a cassette guide for guiding the media guide.
- the cassette guide preferably limits the directions of movement to, in particular precisely, a translatory direction of movement.
- the cassette guide particularly preferably specifies a movement along a processing axis of the set-up system by restricting the directions of movement.
- the cassette guide has a drivable roller guide.
- the drive can be configured to be movable with the drivable roller guide for indirectly driving the media guide from the free-running position into a drive position. This can ensure a particularly secure connection of the drive.
- the drivable roller guide has at least one roller.
- the drivable roller guide preferably has two or more rollers.
- the drivable roller guide can be in positive and/or non-positive contact with the media guide.
- a form-fitting contact can be achieved, for example, by a toothed engagement of a roller in the media guide.
- a non-positive fit can be achieved, for example, by means of a friction pairing between a roller and the media guide.
- the roller guide can thus be adapted particularly flexibly to the media guide.
- At least one roller is particularly preferably designed as a drive roller and/or at least one roller as a support roller.
- the drive roller and the support roller in this case preferably abut opposite sides of the media guide.
- the support roller is designed to run freely while the drive roller for drive transmission from the drive to the Media management is formed. As a result, the media guide can be guided with particularly little friction and, in addition, an effective connection option for the drive can be provided.
- the friction wheel is preferably arranged or attached directly to the drive and follows the movement of the drive.
- the friction wheel for rolling up and/or unrolling the media guide is designed to be movable into a drive position with the media guide and/or the drivable roller guide. As a result, an even more effective drive transmission to the media guide can take place.
- the cassette guide has a guide bush.
- the guide bush is part of the cassette guide and is preferably located downstream of the drivable roller guide on a processing axis in the direction of a pipe to be processed.
- the guide bushing can be designed to accommodate a guide rod arranged on the media guide.
- the guide bushing preferably has a through-hole for this purpose. More preferably, the guide bushing forms a guide stop for the guide rod within the through-hole in a direction of movement, in particular in a direction of roll-up movement, of the media guide.
- the position of the media guide and/or the guide rod is inside the guide bush is determined by a proximity switch, in particular in the form of a non-contact limit switch.
- the proximity switch is preferably arranged in a wall recess of the guide bush.
- the media guide also preferably has a marking. A marking can be in the form of a depression and/or elevation, for example.

- the cassette unit has a cassette holder.
- the cassette holder can be designed as a carrier for the drive cassettes.
- the cassette holder is preferably designed for the detachable arrangement of the at least one, in particular each, drive cassette.
- a detachable arrangement means that the drive cassettes located on the cassette holder can be exchanged in a particularly simple manner.

- the drive unit has a cassette coupling for mechanically coupling the at least one drive cassette.
- a clutch can be designed, for example, in the form of a gripper.
- the drive cassette preferably has a receiving section, in particular a receiving lug, which is designed contrary to the cassette coupling.
- the drive unit can be coupled to the drive cassette particularly quickly and reliably.
- the drive unit can be attached to the drive cassette temporarily and/or permanently by means of the cassette coupling. This is particularly advantageous when the drive cassette is detached from the cassette holder in this case.
- the drive cassette can be moved with the drive unit, in particular along the processing axis. In the case of an internal treatment to be carried out on a short pipe, the drive cassette can therefore be brought up to the end of the pipe by the drive unit, as a result of which the media guide can be introduced in a targeted manner in a particularly reliable manner.
- a preferred embodiment of the set-up system provides that the cassette unit has at least one additional drive cassette.
- the additional drive cassette can be designed identically to the at least one drive cassette.
- the manufacturing costs for the drive cassettes can be reduced.
- the further drive cassette, in particular the cassette guide can differ from the design of the at least one drive cassette. This is advantageous with regard to an adjustment of the additional drive cassette to an additional media guide to be guided.
- the drive is preferably designed to drive the additional media guide of the additional drive cassette.
- the drive is from one, in particular the same, freewheel position to a drive position with the other Media guide designed to be movable. As a result, the same drive can be used particularly favorably to drive multiple media guides.
- the at least one further drive cassette is arranged parallel to the at least one drive cassette.
- the drive cassettes are preferably arranged transversely, in particular orthogonally, to a machining axis. As a result, the drive cassettes can be arranged at the same distance from the pipe to be treated, which is favorable for the process.
- All drive cassettes are preferably detachably arranged on the cassette holder. More preferably, each drive cassette can be secured to the cassette holder by means of a separate lock. This allows access to the individual drive cassettes to be particularly flexible.

- the tube 12 is aligned in the tube receptacle (not shown) in such a way that the tube center axis 16 is concentric with the processing axis 18 is.
- the media guide 28 is then unwound from the drum unit 22 by driving the drive unit 24 . While the media guide 28 is unrolling, the media guide 28 is guided into the tube 12 by the cassette unit 26 up to an end (not shown) of the tube 12 remote from the set-up system 14 .
- the internal treatment of the pipe 12 by the tool 44 then preferably begins, in the present case a medium—for example compressed air, separating agent, electricity—being conveyed to the tool 44 by means of the media guide 28 .
- the media guide 28 is rolled onto the drum unit 22 by the drive unit 24 at the same time or with a time delay.
- the internal treatment of the tube 12 and/or the rolling up of the media guide 28 may be temporarily suspended and resumed. In this way, the intensity of the internal treatment and/or the type of internal treatment can be changed depending on the position of the tool 44 in the pipe 12 .

- the friction wheel 82 has a friction lining, in particular a rubber-elastic one.
- the drive unit 24 can be moved from a freewheeling position into the drive position.
- the friction wheel 82 and the drive 84 can be moved together by means of two adjustment rails 86 into non-positive contact with the cassette unit 26 or the drive roller 74 (an adjustment rail 86 is shown hidden with a dashed line).
- the adjustment rails 86 are preferably arranged in an orthogonal plane of the processing axes 18 . More preferably, the adjustment rails 86 are arranged orthogonally to one another.
- the adjustment rails 86 are particularly preferably designed as a vertically aligned vertical adjustment rail and a horizontally aligned horizontal adjustment rail.
- the drive unit 24 can be arranged on the carriage 36 and can therefore be moved on the rail 34 of the device 10 on an axis parallel to the machining axis 18 (see FIG. 1). As a result, a corresponding adjustment rail 86 can be omitted. Alternatively or additionally, it can be provided that the drive unit 24 has a further adjustment rail 86 in a third spatial direction.
- the further adjustment rail 86 is preferably arranged orthogonally to the other two adjustment rails 86 or parallel to the processing axis 18 . Through this the drive unit 24 can be moved particularly flexibly depending on the design of the cassette unit 26 into the freewheeling position.
- the drive unit 24 has a position sensor 88 for determining the position of the drive unit 24 in relation to the media guide 28 .
- the position sensor 88 is designed here as a non-contact limit switch and is designed to be arranged in the wall recess 78 of the guide bushing 70 .
- the drive unit 24 includes a cassette clutch 90 for mechanically coupling the drive cassettes 42 individually.
- the cassette coupling 90 has a parallel gripper 92 which can be moved along a coupling axis 96 by means of a coupling drive 94—here in the form of a pneumatic cylinder.
- the coupling axis 96 is preferably formed transversely, in particular orthogonally to the machining axis 18 in a plan view of the set-up system 14, or formed in the direction of arrangement of the drive cassettes 42.
- the parallel gripper 92 is in engagement with a receiving tab 98 of one of the drive cassettes 42.
- FIG. 4 shows the cassette unit 26 and the drive unit 24 in a freewheeling position, or in an uncoupled arrangement.
- the individual steps for coupling the drive unit 24 to one of the drive cassettes 42 are described below to explain the functional principle.
- the drive unit 24 is coupled to one of the drive cassettes 42
- the drive 84 and the friction wheel 82 are first moved from the drive position to a free-wheeling position by moving along one of the adjustment rails 86.
- the position sensor 88 is lifted out of the wall recess 78 of the guide bushing 70 .
- the friction wheel 82 is then in no way driving contact with one of the drive rollers 74 of the drive cartridges 42 and the media guide 28, respectively.
- the parallel gripper 92 then releases the coupling with the receiving tab 98 of the drive cassette 42 by moving the parallel gripper 92 along the coupling axis 96.
- the decoupling precedes the movement of the drive unit 24 into the freewheeling position.
- the parallel gripper 92 and the receiving tab 98 it is conceivable for the parallel gripper 92 and the receiving tab 98 to be uncoupled in advance of or at the same time as the movement into the free-wheeling position. As a result, the drive unit 24 is detached from the drive cassette 42 or the cassette unit 26 .
- each drive cassette 42 has two centering elements 100--here in the form of a centering ball and a centering pin--(only one centering pin is visible in the illustration shown).
- the two centering elements 100 of each drive cassette 42 engage in oppositely designed centering recesses 102 of the drive unit 24 during coupling. In the case of the embodiment shown, this can be done by moving the carriage 36 (see Figure 1).
- FIG. 5 shows the drive unit 24 in a coupled arrangement with the cassette unit 26 or the other drive cassette 42.
- the drive unit 24 was moved—for example by means of the carriage 36 (see FIG. 1)—along the processing axis 18 in the direction of the cassette unit 26 .
- the drive unit 24 Upon reaching the drive cartridge 42, the drive unit 24 by means
- the parallel gripper 92 is moved along the coupling axis 96 into engagement with the receiving tab 98.
- the drive unit 24 is now in a coupled state with the drive cassette 42.
- the drive unit 24 is then moved into a drive position with the media guide 28 by lowering the drive 84 and the friction wheel 82 along an adjustment rail 86 onto the drive roller 74 of the drive cassette 42 .
- the cassette unit 26 also has a cassette holder 104 for the detachable arrangement of the drive cassettes 42 .
- the cassette holder 104 can have a pneumatic lock 106 which is designed for the automated release of the drive cassette 42 from the cassette holder 104 .
- the latch 106 is in the form of a bracket 110 pivotable about a pivot point 108 , the bracket 110 having a locking projection 112 .
- a locking cylinder 114 here a compressed air cylinder - the bracket 110 is pressed in the direction of the drive cassette 42 and thus the locking projection 112 into a locking recess (not visible) of the guide bushing 70 .
- the locking cylinder 114 is contracted, as a result of which the bracket 110 is pivoted away from the drive cassette 42.
- the locking projection 112 is therefore not in engagement with the locking recess and the drive cassette 42 can be detached from the cassette holder 104 in the direction of the machining axis 18 .
- the drive cassette 42 coupled to the drive unit 24 can thus be moved by the drive unit 24 along the processing axis 18 by releasing the pneumatic lock 106 .
- the set-up system 14 (FIGS. 1 and 2) can be brought up to pipes 12 (FIG. 1) of different lengths in order to prevent the media guide 28 from sagging or the pipe 12 from missing if the distances between the set-up system 14 and the one to be treated are too great Tube 12 to avoid.
- Fig. 5 shows the cassette unit 26 and the drive unit 24 from the previous figures in a rear view for a better explanation of the locking mechanism 106.
- the cartridge unit 26 is secured to the mounting flange 32 by the cartridge holder 104 and the latch 106 .
- the locking cylinder 114 By expanding or contracting the locking cylinder 114, the yoke 110 can be pivoted relative to the cartridge holder 104 about the pivot point 108.
- each drive cassette 42 has a pneumatic lock 106 for detachable arrangement on the cassette holder 104 .
- the invention relates to a set-up system 14 for a device 10 for treating the inside of a pipe 12, with a drive unit 24 rolling a media guide 28 guided via a drive cassette 42 off a drum 38 and inserting it into the pipe 12. Furthermore, the drive unit 24 is designed to roll up the media guide 28 onto the drum 38 . According to the invention, the drive unit 24 can be moved from a free-running position into a drive position in order to roll up and/or unroll the media guide 28 . The invention further relates to a device 10 for treating the inside of the pipe 12 with such a setup system 14.
