Description

Method and device for producing unround winding tubes made of plastic profiles

Technisches GebietTechnical area

The invention relates to a method for rehabilitating sections of non-circular sewers between two inspection shafts with winding tubes wound from profile strip, in which the abutting edges of consecutive pipe turns of the wound profile strips made of plastic to dense connections latched into the to be rehabilitated sewer insertable winding tube; it further relates to an apparatus for carrying out this method.

Stand der TechnikState of the art

As part of the wastewater discharge usually sewers are used, which are assembled from concrete pipes. These concrete pipes are subject to corrosion by the sewage, so that from time to time renovations are necessary. This is u. a. known to use winding tubes wound from extruded plastic profiles. For remediation, a channel sections between two inspection shafts is selected, in which such a winding tubes is introduced until the end of the section of the sewer to be rehabilitated is reached. To form the winding tube of the supplied through the inspection shaft profile strip is placed in pipe turns and the abutting edges of successive pipe turns of adjacent profile strips locked to dense connections. A manufacturing apparatus for this purpose disclose DE 696 36 214 T2 and EP 2 085 209 A1. In these cases disclosed, the profile strip made of plastic is fed to a winding former, which is fixedly arranged in the region of the mouth of the sewer to be rehabilitated, and in which the profiled strip is placed in pipe turns and the edge regions of adjacent pipe turns are overlapped. In such a production pipe threads are so assembled on pipe turns to the winding tube and inserted in rotation in the channel piece. Therefore, the use of such methods is limited to the rehabilitation of sewers with round cross-section. When used in the area of non-circular channels so significant cross-sectional areas would have to remain unused.

Darstellung der ErfindungPresentation of the invention

A further development thereof can be found in EP 2 085 209 A1, in which the adaptation to deviating diameters and deviating forms is achieved by a chain-like pressing member, in which at least two of the chain links are provided inwardly standing as compensating means. In this case, the supplied from the outside through the renovated channel section profile strip is joined together to pipe turns and the abutting edge regions of successive pipe turns overlapping each other locked together to form a tight connection. In this case, the Wickelfertiger moves according to the manufacturing progress through the channel to be rehabilitated, so that the winding tube is made in place. Due to the moving through the channel section to be rehabilitated paver this approach appears problematic, on the one hand because of the deposited on the wall of the sewer contaminants, and on the other hand, as in faults on the paver repair on site in the canal to be rehabilitated. Since often not too large channel cross-sections of sewers instead of round concrete pipes predominantly non-circular concrete pipes - such as egg-shaped or maulsförmigen profiles - are used, if rehabilitation to occur, remediation by means of the known not or only insufficiently possible.
task
The invention thus raises the problem of proposing a method for rehabilitating even non-circular concrete channels by means of such plastic profile strips and to provide a corresponding device in which the disadvantages of the prior art are avoided.
solution
This problem is specified for a generic procedure or for a generic device with the characterizing features of the independent claims, advantageous developments and preferred embodiments define the dependent claims.
To carry out the method described above, the winding tube is formed from tube turns of a profile strip, which are joined together by a wrapper rotating on a guide rail so that abutting edge regions are brought together and locked. For this purpose, a Wickelfertiger is installed in a revision chamber at the bottom of a first inspection shaft, which has a cross-sectional shape of the channel to be rehabilitated adapted guide rail and a peripheral winding former, and which is installed in front of the mouth of the section to be rehabilitated the channel. These can be provided against the walls of the inspection chamber or the ceiling and floor directed supports. If these supports are mounted on rails, this allows a displacement corresponding to the production progress. In this case, the retraction of the finished winding tube section takes place discontinuously each in the displacement possibility corresponding pieces. A certain mobility of the winding device can also be achieved by hanging the guide rail about chains.
On the inside of the guide rail, a Wickelformer is arranged, which engages around the guide rail with C-profiles laterally and is held on the outside of the guide rail seated Hintergreifungsrollen at this so that it can rotate along the guide rail. For an undisturbed circulation, the guide rail is advantageously assembled from several jumbled together juxtaposed individual pieces, so that the winding former regardless of their shape smoothly rotate on the guide rail and can move the profile strip when it circulates.
In such a procedure of a supply roll of the profile strip is withdrawn so that due to the circulation of the Wickelformers torsion is canceled. To produce the winding tube on site, this profile strip is fed to the former by the first inspection shaft, in the former to form tube turns whose shape corresponds to the shape of the guide rail. together. In this case, the edge region of adjacent pipe turns are locked overlapping each other. Since the winding former follows the guide rail during its movement, each of the shaped pipe turns corresponds to the shape of the guide rail and thus also to the cross-sectional shape of the channel section to be rehabilitated. The winding tube is extended by the width of the profile strip minus the overlap width with each revolution of the Wickelformers. With such a winding tube made of joined together, in their overlapping edge regions latched together pipe turns can thus rehabilitate next channel sections with a round cross section and those whose cross section is out of round, such as sewers with egg-shaped or maulsförmigen profile, since the winding tube thus manufactured in the to be rehabilitated Channel section without rotation by insertion or, especially for long or deviating from a linearity channels also introduced by retraction and so their sewer rehabilitation is possible.
To improve the latching connection, the interconnected edge regions are adhesively bonded, at least in the region of one of the nested grooves, with sealing compound or adhesive. The predetermined by the guide rail shape of the winding tube is advantageously additionally secured by steel wire insert. In this way, a liquid-tight and in itself particularly stable winding tube is obtained.
The winding former has a strip inlet, through which the profile strip is fed. A profile roller ensures that the grooves of the edge region of the last completed pipe turns of the winding tube lie against the adjacent edge region of the supplied profile strip, lock the profiles of both profile strips by means of pressing against the profile strip friction rollers and bring in the predetermined by the guide rail shape. In order to effect the circulation of the Wickelformers on the guide rail, the Wickelformer is provided with at least one drive. For this purpose, the electrically or hydraulically driven motors acting on friction and drive rollers on the run-in and formed for winding and on the adjacent profile strip and thus effect the propulsion of the Wickelformers as well as the tightening of the profile strip. In order to achieve a sufficient power transmission, the pressure rollers interact with profiled counter-rollers. Advantageously, the turns facing the upper side of the body of the Wickelformers profiled. In these profiles, the outward profiling of the assembled profile strip is pressed and locked.
In order to be able to pass through the possibly tight curves of the guide rail in non-circular cross-sections, the winding former is advantageously designed in several parts. In this case, the band inlet facing part as Vorverformer and the tape outlet facing part are designed as a final paver. Especially with large dimensions, it may be advantageous if further intermediate parts are inserted between Vorverformer and finished the Wickelformers. Furthermore, it is advantageous for the mobility of the Wickelformers when the individual parts of the Wicklungsformers are pivotally hinged to a rocker. Advantageously, at least the preformer as well as the final paver each have their own drive, wherein each of the drives cooperates with the guide rail via friction rollers.
With each revolution of the Wickelformers on the guide rail, a new Rohrwindung from the profile strip is placed on the existing pipe turns, so that each circulation has an extension of the finished winding tube to a strip width result. The drives can also act on the profile and / or pressure roller in the strip entrance, which bring together the edge region of the incoming profile strip at the overlapping edge regions of the already entered and formed to the winding edge region of the previous turn.
For driving the Wickelformers electric or hydraulic motors are provided, the energy supply preferably takes place close to the center of the guide rail. For an undisturbed circulation of the former on the guide rail while rotary connections for the electrical or hydraulic lines are provided, is counteracted by their orbital torsion. In order not to hinder a free shrinkage of the profile strip in the winding former, it is advantageous if the energy is supplied through the channel section to be rehabilitated. Since in this case the electrical or hydraulic lines run to the stationarily arranged Wickelfertiger, these are also stationary. The drive motors act via friction rollers on the guide rail and thus cause the movement of the Wickelformers. In order to achieve full revolutions of the rewinder, especially in narrow bends or large diameters, it may be advantageous to provide an auxiliary drive on the winder. This is provided as a force or frictional drive to the former, which acts directly on the guide rail. Advantageously, the guide rail is provided with a corrugation or a toothing, which interacts with the output gear of the auxiliary drive to provide the necessary for the desired movement adhesion. This auxiliary drive is advantageous hinged to the connecting the preformer and the final paver rocker and thus also against these swivel.
The profile strip used for refurbishment is removed from a supply roll at the mouth of the (first) inspection shaft so that the rotation of the profile strip occurring during each revolution of the rewinder is canceled. For this purpose, the profile strip is withdrawn from the standing and held in position drum similar to a streamer, each of the withdrawn drum windings compensates for a caused by the circulation of the winding former Torsionswindung. The sense of winding of the profile strip on the storage drum is directed against the rotation caused by the rotation of the former. Alternatively, the drum is rotated accordingly, wherein the direction of rotation is directed by the rotation of the winding former caused torsion of the profile strip opposite. For this purpose, the drum is placed on a turntable above the shaft mouth (the installation is elevated for safety reasons at a height that allows escape from the inspection shaft in case of danger). Alternatively, the drum is moved around the shaft mouth, wherein the direction of rotation of the conditional by the circulation of the winding former torsion of the profile strip is directed against.
By winding around the guide rail Wickelformer the finished winding tube can be introduced without twisting in the rehabilitated channel section round or non-circular shape. For this purpose, the manufactured winding tube is inserted into this or - retracted - especially for longer sections of the canal to be rehabilitated. The latter counteracts the risk of compression of the winding tube, so that is preferred in this also in dislocations or bows. It goes without saying that insertion and withdrawal can also be combined.
In special cases, it may be necessary to shift the wrapper according to the manufacturing progress of the mouth of the channel section to be rehabilitated away. For this purpose, this is placed on a bottom of the inspection chamber base plate and supported by at least one support against the ceiling and / or walls, wherein the base plate movable on a bottom rail and the support / supports are formed with slidably designed as sliding shoes on ceiling rails. At least for the movement of base plate with Wickelfertiger a base plate drive is provided for retrieving.
To secure the latched overlaps of adjacent profile strips, a bond or seal is provided. The supply of an adhesive or a sealant (hereinafter referred to as "adhesive" in the following) takes place together with the power supply via the extension arm directed towards the center of the guide rail. An adhesive reservoir with pump, which arranged to compensate for the conditional by the rotating winding former torsion on the upper plate of the turntable Aufständerung the supply roll of the profile strip. The adhesive line is guided together with the withdrawn profile strip through the first inspection shaft to the wrapper. Alternatively, the adhesive supply is provided by the second inspection shaft, wherein the adhesive line is guided together with the hydraulic lines through the second inspection shaft to the wrapper and connected via a rotary connection to the Wickelfertiger.
For introducing the adhesive between the edge regions to be joined together of the last produced tube winding of the winding tube and the supplied profile strip leads connected to the rotary connection adhesive supply with adhesive nozzle between these edge regions that leaking adhesive enters the Verrastungsbereich and there under the action of profile roll and pressure roller is applied and distributed. For this application, the adhesive nozzle - because of the circulation of the Wickelformers - grazing brought to the adhesive groove receiving the adhesive. A special stability is achieved when the profile strip used is extruded from a thermoplastic elastomer with the introduction of a jet insert.
The introduction of the produced winding tube into the channel section to be rehabilitated is carried out primarily by advancing, wherein the winding tube grows by a length at each revolution of the former one of the width of the profile strip minus the width of the overlap. In order to avoid upsets in longer to be rehabilitated sections of the channel, a pulling device is provided which engages the free end of the finished winding tube. the manufactured winding tube moves in accordance with the progress of production quasi-continuously in the rehabilitated section of the channel. For this purpose, a traction device is provided which is arranged either in the next-following inspection shaft, wherein the traction cable is guided through the channel section to be rehabilitated, or is provided for days near the shaft mouth of the second inspection shaft, wherein the traction cable through the second inspection shaft and the renovating channel section is performed.
This pulling device is either controlled by the production and pulls the winding tube continuously following the production progress into the channel section. Alternatively, a discontinuous feeder, in which the Wickelfertiger movably placed in his inspection chamber and the production progress is shifted accordingly away from the channel mouth until a predetermined by the width of the inspection chamber length of the winding tube is made. This is then pulled by means of the pulling device, which acts on the manufactured winding tube, which then retracted into the channel piece section to be rehabilitated.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Figures 1, 2 and 3 show schematically the rehabilitation of a channel section 3. This takes place, starting from a first inspection shaft 1 to a second inspection shaft 1 ', in sections by means of one of the (described in detail below in more detail) Winder 20 from a profile strip 4.1 produced profile tube 4.1 is withdrawn from a supply of tape on a storage drum 5, which is placed above ground during renovation of underground sewer pipes 3. The profile strip 4.1 is fed to the wrapper 20 through the inspection shaft 1. This is placed on site at the bottom of the first inspection shaft 1 at the beginning of the rehabilitated channel 3 arranged revision chamber 2 and has a guide rail 25 on which a Wickelformer 30 is arranged so that it can rotate freely on the guide rail 25.
Since the profile strip 4.1 is twisted during each revolution of the winding former 30, as shown in FIG. 2, its removal from the storage drum 5 takes place in a similar manner in the case of a stationary storage drum 5. Alternatively, held by a drum holder 5.1 storage drum 5 is placed on a turntable with saucer 6.1 and top plate 6.2 on the shaft mouth 1.1 on an elevation 7 so that the conditional by the circulation of the former 35 torsion of the profile strip 4.1 with the rotation obtained during its withdrawal the storage drum 5 this twist is canceled. The rotation of the upper plate 6.2 can be supported with a motor drive 6.3.
3 shows in simplified form the merging of the profile strip 4.1 in the schematically illustrated winding former 30 to the last of the turns of the already wound winding tube 4. This profile strip 4.1 is guided by the supply drum 5 through the first inspection shaft 1 (FIG. 1) to the wrapper 20 and into introduced the winding former 20. In this case, the profile strip 4.1 runs in the winder 20, that its smooth side 4.2 facing the inner wall of the winding tube 4, this forms, wherein provided in the profiles page 4.3 of the profile strip 4.1 are directed with the side locking strip 4.4 to the outside. The Wickelformer 30 runs on the guide rail 25, which leads to the torsions of the profile strip 4.1 (not specified). The profile strip 4.1 supplied by the strip guide 40 (FIG. 5) to the former 30 is taken over by the profile roller 34.1 such that its edge region 4.4 facing the last turn of the finished winding tube 4 and the round section of the profile strip binding this last turn lie one above the other and by the counterpressure the pressure roller 32.3 interlock. Under the pressure of the drive rollers 33.1 and 33.2 of preformer 30.1 or final paver 30.2 then takes place by means of the back pressure of the pressure rollers 34.1 us 34.1 the final locking, so that the newly formed turn is firmly connected to the previous turn. About the (only in Fig. 7) glue supply 54 is the adhesive from the reservoir 50 with the adhesive pump 51 (both Fig. 1) peeled adhesive between the edge region to be joined together 4.4 of the profile strip 4.1 and edge region of the last turn of the winding tube 4 forming Profile strip introduced, which then distributed appropriately ensures a secure and tight connection of the merged edge areas.
As an alternative embodiment according to FIG. 2 b, a movable installation of the winding handler 20 in the inspection chamber 2 effects a discontinuous drawing in each case of the manufactured section of the winding tube 4 by the pulling device 10 '. For this purpose, the Winder 20 stands on a base plate 21 which is placed on floor rails 22. Further ceiling rails 24 are provided for the against the ceiling of the inspection chamber 2 and their walls directed supports 23, on which the trained as sliding shoes 23.1 free ends of the supports 23 are guided. The winding fabricator 20 set up in this way can be removed from the mouth of the channel 3 to be rehabilitated in the inspection chamber 2 in accordance with the production progress. The manufactured winding tube 4 is drawn in discontinuously, wherein the maximum length of the width of the inspection chamber 2 corresponds.
FIGS. 4a and 4b show the wrapper in the bottom of the first inspection shaft. The thus manufactured winding tube 4 is inserted according to the manufacturing progress in the channel 3 to be rehabilitated. In order to counteract an upsetting of the winding tube 4 caused by manufacturing progress in the case of long or uneven channels, the hand-winding device 20 has a certain movability, which-as shown in FIG. 4a-can be achieved in the simplest case by suspension 24.1, for example at a transverse rail 24 , Alternatively, the wrapper 20 is supported with supports 23 against the bottom, the ceiling and / or the walls of the inspection chamber 2. Furthermore, it is advantageous if the Winder 20 stands on a base plate 21.
A movable installation of the wrapper 20 in the inspection chamber 2 shown in FIG. 4b is advantageous for a discontinuous drawing in each case of the manufactured section of the winding tube 4 by the pulling device 10. For this purpose, the Winder 20 stands on a base plate 21 which is placed on floor rails 22. Further ceiling rails 24 are provided for the against the ceiling of the inspection chamber 2 and their walls directed supports 23, on which the trained as sliding shoes 23.1 free ends of the supports 23 are guided. The turn-up fabric 20 set up in this way can be removed in the inspection chamber 2 according to the progress of production from the mouth of the channel 3 to be rehabilitated. The manufactured winding tube 4 is drawn in discontinuously, wherein the maximum length of the width of the inspection chamber 2 corresponds.
Advantageous is a shown in Fig. 4c interaction of the Wickelfertigers 20 with a pulling device 10, which acts on the end of the finished winding tube 4 via a arranged on a frame 12, provided with a drive motor 13 reel 11 engageable traction cable 14. This traction device 10 can be found either in the located at the end of the section to be rehabilitated portion of the channel 3 Revision 2 'of the second inspection shaft 1' lineup. Alternatively, the traction cable 14 is guided by the traction device 10 set up over days - as shown in FIG. 1 - through the shaft mouth 1.1 'of the second inspection shaft 1' to the traction insert 15, to which the traction cable 14 is struck for advancing the finished winding tube 4 , In this case, the reel 11 is advantageously controlled so that the finished winding tube 4 is retracted following the manufacturing progress in the channel 3 to be rehabilitated.
Figures 5 to 8 show the Winder 20 with winding former 30 and details of the Wickelformers 30. For producing unround Wickelrohre 4 runs on the cross-sectional shape of the channel to be rehabilitated adapted guide rail 25 of the Wickelformer 30 with feed 40 for the processed profile strip 4.1. Thus, the guide rail 25 of the desired design can be adapted without further and the winder 30 can circulate on this without inhibition, the guide rail 25 is suitably joined together from several sections 26, which merge smoothly into each other at the joints 27. On the guide rail 25 of the winding former 30 is guided with the guide rail 25 laterally embracing C-profiles 31.1 and 31.2 and held with the guide rail 25 engages behind counter-holding rollers 32.1 and 32.2. This training requires a secure fit of the wrapper 30 on the guide rail 25 and its free mobility on this.
In order to allow this free circulation even with narrow curvatures of the guide rail 25, the winder 30 is advantageously made of several parts - in the illustrations, two parts are shown, the one as Vorverformer 30.1, the other as a final pawn 30.2 - put together, the both sides of wings 30.3 are articulated. In order to hold the winding former 30 on the guide rail 25, 31 C-shaped guide shoes 31.1 and 31.2 are provided on the base body, provided with the guide rail 25 engaging behind retaining rollers 32.1 and 32.2, to effect this holding.
The thus manufactured winding tube 4 is - as shown in Figures 4 - pushed the production progress accordingly in the rehabilitated channel section 3 or retracted. In order to counteract an upsetting of the winding tube 4 caused by manufacturing progress in the case of long or uneven channels, the hand-winding device 20 has a certain movability, which in the simplest case by suspension 24.1, for example, on a holder in the region of the shaft mouth 1.1 of the first inspection shaft 1 or on a in the inspection room 2 arranged ceiling rail 24 can be achieved. Alternatively, the wrapper 20 is supported with supports 23 against the bottom, the ceiling and / or the walls of the inspection chamber 2. Furthermore, it is advantageous if the winding fabricator 20 stands on a base plate 21, especially if it is movable on the rail 22.
The supplied profile strip 4.1 is taken over by a strip inlet 40 arranged on the pre-deformer 30.1 and placed in the pre-deformer 30.1 and during its movement along the guide rail 25 in pipe turns which follow one another such that the edge regions of two successive pipe turns overlap. The merging of the profile strip 4.1 with the winding tube 4 is shown schematically in Fig. 7. The profiling of both the profile strip 4.1 as well as the winding tube 4 is represented by the (weaker drawn) parallel line. Between profile roller 34.1 and pressure roller 36.1 takes place the merging and between the friction rollers for the drive 33.1 and 33.2 and with these cooperating correspondingly profiled counter rollers 33.3 and 33.4 (only Fig. 8 - due to the representation of Figure 5a, only the interacting with the pressure roller 32.2 profile roller 34.2 can be seen) Locking the merging in interlocking edge profiles of the last of the manufactured pipe winding of the winding tube 4 with the supplied profile strip 4.1.
The edge region of the profile strips 4.1 provided with profilings corresponding to one another engage in one another during assembly and are thereby locked in a manner known per se to the winding tube 4. Thus, with each revolution of the Wickelformers 30 on the guide rail 25, the length of the winding tube 4 so to the reduced by an overlap width width of the profile strips 4.1.
Advantageously, the profiled strip 4.1 facing upper side of the base body 31 of Vorverformer 30.1und final pawn 30.2 - as well as between both inserted further sections of the Wickelformers 30 - profiled according to the profile of the profile strip 4.1. In this - not shown in the figures - profiling is the outwardly directed profile of the winding tube 4 shaped and assembled profile strip 4.1 and is pressed under the pressure of the pressure rollers 32.1 and 32.1 and locked so. Further, by this profiling, the power transmission from the pressure rollers 32.1 and 32.2 on the smooth inside of the wound tube 4 molded and assembled profile strip 4.1 and thus also the propulsion of the Wickelformers 30 is improved.
The production of the winding tube 4 from the supplied profile strip 4.1 by means of the rotating on the guide rail 25 of the Wickelfertigers 20 Wickelformers 30. This is to achieve good mobility for circulation especially at narrow curved guide rails, executed in several parts. It is the feed 40 for the profile strip to be processed facing 4.1 part as Vorverformer 30.1 and its subsequent part as a final pawn 30.2, which are connected via a rocker 32 to which these two parts are pivotally connected. Between these two parts more parts can be inserted as intermediate links, which is particularly advantageous for large dimensions of the winding tube to be produced.
For circulating on the guide rail 25 of the arranged thereon former 30 is equipped with its own drive. In the case of multi-part winding formers 30, each of these parts 30.1, 30.2 advantageously has its own drive motor 36.1, 36.2 which, acting on the friction rollers 33.1, 33.2, effects the locomotion of the winding former 30 on the guide rail 25. In this case, these friction rollers 33.1, 33.2 interact with the last-placed pipe turn of the finished winding tube 4 and with the accumulated profile strip 4.1. It goes without saying, to provide other drives instead of the friction rollers.
For this purpose, the two parts 30.1, 30.2 of the winder former 30 have the profile of the guide rail 25 laterally receiving C-profiles 31.1 for the pre-deformers 30.1 and 31.2 for the final paver 30.2, which are respectively corresponding counter-holding rollers 32.1 and 32.2, which are the recorded Engage behind the edge region of the guide rail 25 and so for a secure fit both the Vorverformers 30.1 as well as the final paver 30.2 of the Wickelformers 30 on the guide rail 25 concern. The friction rollers 33.1 and 33.2 act on the winding tube 4 to be reshaped profile strips 4.1 and cause so next to the circulation on the guide rail 25 retraction of the profile stiffener 4.1 and its laying in pipe turns, adjacent edge areas are overlapping joined together. The drives 36.1 and 36.2 act on countershaft gears 36.1 and 36.2 on the friction or drive rollers 33.1 and 33.2 of each of the parts 30.1 and 30.2 as well as on their locking the edge regions adjacent pipe turns of profile strips causing profile rollers 34.1 and 34.2, their design at least corresponds to the profile of the edge regions of the profile strip used for manufacturing 4.1, and thus provide an adjustment of the output speed of each of the drives 36.1, 36.2 with respect to the for the propulsion of the winding former 30 via the friction or drive rollers 33.1, 33.2 and for the from the profile rollers 34.1 and 34.2 required speeds.
In order to achieve a gluing or sealing in the region of the overlap of two adjacent profile strips, adhesive or sealant is supplied. For this purpose, in Figure 1 in addition to the lines for the hydraulic flow 46.1 and the hydraulic return 46.2 a third line is provided as adhesive line 52, on the adhesive, the adhesive reservoir 50 with a pump 51 - shown in the illustration as a submersible pump - are removed can, the winding former 30 is supplied via the adhesive line 52. This is performed together with the lines 46.1, 46.2 through the second inspection shaft 1 'with inspection chamber 2' in the not yet or partially rehabilitated portion of the channel 3, which ends at the winding former 30, wherein in the inspection chamber 2 'pulleys for the lines can be provided as needed. On winding former 30 corresponding hydraulic rotary connections 47 and for the adhesive line 52, an adhesive rotary connection 53 are provided to compensate for the caused by the circulation torsions for the hydraulic lines 46.1, 46.2, which advantageously provided on a directed to the center of the guide rail 25 boom arm 40.1 are.
Of the hydraulic rotary joints of the hydraulic flow and the hydraulic returns are guided to a hydraulic distributor 47. Of its outputs 47.1 for the drive 36.1 of Vorverformers 30.1, 47.2 for the drive 36.2 of the final pawn 30.1 and - if provided - 47.3 for the drives 36.1 and 36.2 of the Wickelformers 30 supporting, acting directly on the guide rail 25 auxiliary drive 43 (unspecified ), the lines for hydraulic supply and return are led to the corresponding motors. The adhesive line 52 runs from its rotary connection 53 via an adhesive feed 54, which opens into an adhesive nozzle 55. This lies between the mutually latched edge regions of the last pipe turn of the already manufactured winding tube 4 and the following tube winding of the supplied profile strip 4.1 and thus allows the adhesive passes into this overlap region and between two or more ribs of Verrastbereichs the profile strips. In order to securely apply the adhesive in the over-head position caused by the circulation of the winder 30 on the guide rail 25, the nozzle mouth of the adhesive nozzle is grazing on the groove receiving the exiting adhesive between the ribs of the respective edge region, preferably of the supplied profile strip. In this way, the bonding in the formation of a winding tube can be realized by means of a Wickelfertigers 20 with rotating winder 30, which also understands itself that the adhesive supply 50 also provided on the supply drum 5 for the supply of profile strip 4.1 supporting upper plate 6.2 is, wherein the adhesive line 52 is supplied to the wrapper 20 together with the peeled profile strip 4.1. In this list, it requires because of the installation on the strip trigger correspondingly rotating turntable 6.2 no additional rotary connection for the adhesive line.
FIG. 8 shows the connection of the supply lines to the winding former 30. The hydraulic drives 36.1 and 36.2 thereof are supplied with energy via the hydraulic lines for the supply line 46.1 and for the discharge line 46.2 which are connected to the hydraulic generator 45. Feeding takes place via rotary connections 47.1 and 47.2, with which the torsion of the lines 46.1, 46.2 and also of the adhesive line 52 caused by the circulation of the reel former 30 is compensated. Their (unspecified) outlets go to a hydraulic distributor 48, which distributes the hydraulic fluid through the terminals 48.1 and 48.2, respectively for flow and return to the individual, the friction rollers 33.1, 33.2 driving hydraulic motors 36.1 and 36.2. The third connection 48.3 supplies the auxiliary drive 43 (FIG. 6). The glue line 52 coming from the glue pump 51 is fed via the rotary connection 53 to the winding former 30. The outlet of the rotary connection 53 leads via the adhesive feed 54 to the merging of already manufactured winding tube 4 and the profile strip 4.1 leads and opens into an adhesive nozzle 55 arranged between these two in the overlap region.
A control station 49 with a hydraulic device 45 (Figure 1) provides the power for the drives designed as hydraulic motors; a switchgear 49.1 allows the control and monitoring of the system. The hydraulic device 45 also has an adhesive reservoir 50 with - shown as a submersible pump - 51, at the output of the adhesive line 52 is connected, via which the adhesive is supplied to the winding former 30. The hydraulic hoses 46.1, 46.2 as well as the adhesive line 52 are connected to the winding former 30 of the stationarily erected turntable 20 and thus remain stationary in the channel. According to the manufacturing progress, they are overlapped by winding tube 4.
