Definitions
- the invention relates to a drum unit, in particular for a set-up system, with a drum for rolling up and unrolling a media guide.
- the invention further relates to a set-up system with a drum unit.
- the invention also relates to a device for treating the inside of a pipe.
- Conventional drum units for the above purpose are used to store media guides in a space-saving manner.
- the weight and the inertia of the drum used and therefore the resistance forces and moments produced by the drum change as a function of the unwinding or winding state.
- DE 10 2010 047 589 A1 discloses a mobile device for the internal treatment of pipes, in particular coolant pipes Steam condensers and heat exchangers known.
- the device has a drum drive for rotating the drum while an application hose is being rolled up and unrolled.
- the device has a further drive—synchronized with the drum drive—for inserting the application hose into the pipe to be treated.
- the use of several motors leads to high manufacturing and operating costs and the synchronization requires a complex design that is prone to errors.
- the device must first be aligned in a corresponding starting position and then operated manually. With regard to the most automated possible internal treatment of pipes, these are only insufficient prerequisites.
- DE 2101907 A1 discloses a method for coating the inner walls of pipes and a corresponding device.
- a flexible hose provided for coating the inner walls of the pipe is wound onto and off the drum by a driven drum.
- EP 0 042 207 A1 discloses a process and a method for wetting an inner wall of a pipe, particularly in the case of long pipes with a small diameter.
- a coaxial hose for the separate conveyance of compressed air and paint is arranged on a drum so that it can be wound up and unwound.
- the drum is driven by a belt drive for winding and unwinding.
- the drives used in the three previous devices are designed to be correspondingly powerful in order to allow both unwinding and winding up of the traction cable, the flexible hose or the coaxial hose accomplish.
- the large dimensioning of the drive leads to high production and operating costs.
- DE 10 2019 106 847 A1 discloses a device for introducing a parting agent into a hollow workpiece.
- the separating agent is conveyed within an energy guiding chain.
- the energy guiding chain can be rolled up on a chain drum.
- the chain drum is designed for passively rolling up the energy transmission chain, for example by means of a spring element.
- the passive element - here the spring element - must be correspondingly prestressed when the energy guiding chain unrolls, which leads to additional loading and dimensioning of the drive.
- the object is achieved by a drum unit, in particular for a set-up system, having at least one drum designed for rolling up and/or unrolling a media guide and a restoring device with at least one force element and one converter element.
- the converter element according to the invention can be designed to change, in particular to increase or decrease, a restoring force provided by the force element.

- the converter element can be designed, for example, as a mechanical, form-fitting, force-fitting, hydraulic gear and/or as a coupling gear.
- the converter element can particularly preferably be designed as a cable pull. In other words, the converter element can also be understood as a force transmission device.
- the restoring device for transmitting a restoring torque when the media guide is rolled up is arranged on the drum. Furthermore, according to the invention, the resetting device is arranged in a freely running manner on the drum when the media guide is unrolled. Thus, in a particularly advantageous manner, the drive can be assisted when the media guide is rolled up onto the drum, while the media guide can be unrolled without additional resistance from the restoring device.
- the restoring device is preferably permanently arranged or fastened to the drum. This eliminates the need for a costly coupling of the resetting device to the drum.
- the restoring torque is provided by means of a translatory movement, in particular by means of contraction or expansion, of the force element.
- the at least one force element is designed as a unidirectionally operated pneumatic cylinder.
- the pneumatic cylinder can provide a restoring force by applying pressure, which can bring about a restoring torque on the drum by means of the converter element.
- the pneumatic cylinder can be varied in this way with pressure be acted upon that a uniform rolling up of the media guide can be guaranteed.
- the pneumatic cylinder is preferably switched against the ambient pressure, as a result of which the pneumatic cylinder can be moved into a starting position without significant resistance forces.
- the unidirectionally operated pneumatic cylinder can be designed during rolling to compensate for the resistance forces caused by the pneumatic cylinder by applying pressure.
- the restoring device can be arranged on the drum even more freely, ie having an even lower resistance.
- the unidirectionally operated pneumatic cylinder is preferably connected to an, in particular automated, pneumatic control system.
- the resetting device can thus advantageously be controlled without human intervention.
- the control system can be set up such that the pneumatic cylinder is subjected to variable pressure when the media guide is rolled up, ie in particular during the return movement of the media guide from a tube, such that a uniform return movement is made possible.
- the drum unit in which the converter element is designed as a cable pull, in particular as a pulley block.

- the converter element is arranged on the drum by means of a cable drum.
- the cable drum is preferably designed for at least partially rolling up and/or unrolling the cable pull. In other words, when there is a change in the distance between the power element and the drum, excess and/or required cable of the cable pull is rolled up on the cable drum or unrolled from the cable drum. As a result, the cable can be made more robust without moving rollers.
- the resetting device is arranged on at least one, in particular each, side of the drum.

Alternatively or additionally, it can be provided that one of the at least two drums differs from at least one other drum in terms of dimensions and/or the material. As a result, the drum can advantageously be adapted to the media guide to be arranged on the drum.
- the at least two resetting devices can be arranged in parallel on the drum unit. At least one restoring device is preferably arranged on each drum. The restoring devices are also preferably arranged on the drum unit so as to be uncoupled to one another. As a result, the restoring device can remain in a rest position when the drum is not in use.

- Fig. 2 shows the set-up system 14 of the device 10 from Fig. 1 in a representation detached from the device 10 without the support structure 30 of the drum unit 22.
- the drum unit 22 has two parallel and concentrically arranged drums 38 . Each drum 38 is configured for arranging a media guide 28 to be rolled up and unrolled. In the embodiment shown, the media guide 28 is arranged on only one drum 38 . To guide the media guides 28, the drum unit 22 has a drum-side roller guide 50 with two rotatable rollers. The drum-side roller guide 50 is designed to guide the media guide 28 along the processing axis 18 and prevents movement of the media guide 28 transversely to the processing axis 18.
- the drum unit 22 has two restoring devices 52 which, in order to support the drive unit 24 while the respective media guide 28 is being rolled up, form a restoring torque 54 on the respective drum 38 .
- the restoring devices 52 each have a force element 56, here in the form of a pneumatic cylinder, and a converter element 58, here in the form of a cable pull.
- Each pneumatic cylinder can be connected to a controllable pneumatic system (not shown) via compressed air connections 60, 62.
- a piston (not visible) guided inside the pneumatic cylinder can be deflected with a piston rod 64 guided on the piston.
- the piston rod 64 is deflected upwards in a vertical direction.
- the pneumatic cylinder or the power element 56 are expanded.
- the force element 56 is contracted, or the piston rod 64 is moved downwards in a vertical direction, if there is a negative pressure gradient between the pressure connection 60 and the pressure connection 62 of the same pneumatic cylinder.
- the restoring device 52 forms a restoring torque 54 on the drum 38 only while the media guide 28 is being rolled up onto the drum 38 .
- the reset device 52 is in a freewheel.
- this can be done by applying pressure to the pressure connections 60, 62 while the media guide 28 is rolling.
- the drive unit 24 can advantageously be designed essentially with regard to overcoming the frictional forces occurring on the media guide 28 . This has a particularly advantageous effect on the manufacturing and operating costs.

- the drums 38 are mounted in a row on the support structure 30 (see FIG. 1) so as to be rotatable along an axis of rotation 66 .
- the number of drums 38 can be changed particularly easily.
- one or more drums 38 can be dismantled, exchanged or upgraded in a particularly simple manner.
- the media guide 28 is particularly advantageously already arranged on the drum 38 .
- the axis of rotation 66 is preferably transverse—in this case perpendicular—to the machining axis 18 .
- the media guide 28 can be rolled up and unrolled particularly precisely.
- the drums 38 can differ in their dimensions, for example drum diameter, drum width, and in terms of their material.
- the drums 38 are preferably adapted to the media guide 28 to be rolled up or unrolled.
- the drums 38 preferably have the same receptacle for arrangement on the axis of rotation 66, regardless of their dimensions and/or materials. This allows the drum unit 22 to be equipped with dedicated drums 38 in a particularly advantageous manner.
- the drums 38 are of identical design, which has a particularly favorable effect on the production costs of the drums 38 due to the higher proportion of structurally identical components.
- the drums 38 each have a first axial drum portion 68 and a second axial drum portion 70 .
- the first axial barrel portion 68 and the second axial barrel portion 70 are preferably formed separately from one another.
- the media guide 28 is arranged in the first axial drum region 68 .
- the media guide 28 is both rolled up and unrolled in only the first axial drum region 70 .
- the media guide 28 is designed as a drag chain.
- the media guide 28 is designed as a hose.
- the media guide 28 is designed to guide at least one media line (not shown).
- the media guide 28 has better guiding properties and greater mechanical robustness than the at least one media line. This enables the media guide 28 to be introduced into the pipe 12 to be treated in a particularly reliable manner (see FIG. 1).
- the media line can be effectively protected against external influences, mechanical stress and/or damage by means of the media guide 28 .
- the at least one media line is preferably arranged inside the media guide 28 .
- the media guide 28 particularly preferably completely encloses the at least one media line. As a result, the media guide 28 can be protected particularly effectively.
- the media guide 28 can advantageously guide two or more media lines. As a result, the media guide 28 can be used even more effectively without any significant additional design effort.
- the media guide 28 is designed to guide at least one media line (not shown).
- Media lines can be, for example, separating agent lines, compressed air lines and/or electrical lines.
- the media line is guided to the tool 44 within the media guide 28 .
- a release agent dispensing tool 44 is the media line designed as a separating agent line and ends in one or more nozzles of tool 44.
- the second axial barrel portion 70 of each barrel 38 includes a supply guide 72 .
- the supply guide 72 is both rolled up and unrolled only in the second axial drum region 70 .
- the supply guides 72 serve to guide at least one supply line (not shown).
- Supply lines are designed to supply the media lines.
- the type and design of the supply lines guided in the supply guide 72 preferably corresponds to the type and design of the media lines guided in the media guide 28 .
- the umbilicals are connected to the media lines between the first axial barrel portion 68 and the second axial barrel portion 70 .
- the first axial barrel portion 68 and the second axial barrel portion 70 may be configured differently.
- the first axial barrel portion 68 may differ from the second axial barrel portion 70 with respect to an axial and/or radial extent.
- the first and/or second axial drum area 68, 70 can thus advantageously be adapted to the respective media guide 28 or supply guide 72 to be rolled up and/or unrolled.
- the supply guide 72 is either unwound from the drum 38 and/or rolled up, depending on the principle.
- the decisive factor here is that the connection of the supply lines to the media lines follows the rotary movement of the drum 38 . In other words, there is no relative movement between the first axial drum area 68 and the second axial drum area 70. This advantageously eliminates the need for a rotary passage through the center of rotation of the drum 38, which improves the tightness, robustness and interchangeability of the drum unit 22.
- the supply lines can therefore be connected to the media lines with a radial spacing from the axis of rotation 66 .
- the supply lines are preferably connected to the media lines close to the axis of rotation 66 .
- each restoring device 52 is arranged on one side of the respective drum 38 by means of the converter element 58 .
- the respective converter element 58 is arranged on both sides of a drum 38 . This can prevent the drum 38 from yawing.
- FIG. 4 shows the drum unit 22 from the previous figures in a rear view with the drums 38 and the restoring devices 52.
- the deflection rollers 74 and the cable drum 76 of a converter element 52 are provided with a reference number.
- the drum unit 22 and thus the drums 38 are in a rolled up condition. Both of the media guides 28 and the supply guides 72 are rolled onto the respective drums 38 .
- the cable drums 76 are in an unwound state.
- the resetting device 52 of the drum 38 is arranged so that it runs freely on the drum 38 .
- the cable of the converter element 52 is wound onto the cable drum 76 .
- the piston rod 64 of the force element 56 designed as a pneumatic cylinder is moved in the vertical direction upwards into a end position pulled.
- the force element 52 is expanded by rolling the media guide 28 .
- the end position is preferably only reached after the entire media guide 28 has rolled off the drum 38 .
- the force element 52 or the pneumatic cylinder 56 can support the extension of the piston rod 64 by applying pressure, so that no torque counteracting the rotational movement according to arrow 78 occurs on the drum 38 .
- the rolling up of the media guide 28 takes place in the opposite manner to the unrolling of the media guide.
- the force element 52 or the pneumatic cylinder is actively contracted or the piston rod 64 is retracted and a restoring torque 54 (see FIG. 2) is thereby applied to the drum 38 .
- FIGs 5a and 5b show a drum 38 of the drum unit 22 (see Figures 1 to 4) shown detached for further explanation.
- the drum 38 has a first axial drum portion 68 for locating the media guide 28 and a second axial drum portion 70 for locating the supply guide 72 .
- the diameter of the drum 38 is formed in two stages in the axial extent of the drum 38 .
- the first axial barrel portion 68 has an outside diameter 78 and the second axial barrel portion 70 has an outside diameter 80 .
- the outer diameter 78 here has approximately twice the value of the outer diameter 80 .

- the drum 38 can be particularly advantageously adjusted to the length of the reel to be rolled up and/or unrolled Media guide 28 and / or supply guide 72 and the required drum revolutions for winding and / or unwinding can be adjusted.
- Both the media guide 28 and the supply guide 72 can be rolled up exclusively in a radial direction of the drum 38, as shown here.
- rolling up of the media guide 28 and/or the supply guide 72 in the axial direction can be limited, in particular completely prevented.
- crossings of the rolled-up media guide 28 or supply guide 72 can be avoided in a particularly effective manner.
- Such a rolling up can also advantageously allow the unrolling to take place without changing the unrolling angle, as a result of which the media guide 28 and/or the supply guide 72 can be designed to be particularly stiff with respect to a transverse direction.
- tool for internal treatment of the tube 12 tool centering means 44;
