Description

Cleaning device for pipes, hoses or the like

The invention is generally concerned with the problem of cleaning hoses and pipes, in particular pipes and hoses for vacuum cleaners and drying systems. In the context of the invention, these are collectively referred to as “hose”. These hoses are connected to an aggregate, that is to say a drying device or the like.

Disadvantages of the prior art

So far, such hoses have been separated from the associated unit, e.g. vacuum cleaner, drying device or the like, and then cleaned of dirt, fungi, mold, sponge and the like using a cleaning liquid, in particular with a high-pressure cleaner.

This procedure is manual and therefore complex. In particular, the mounting of the hoses or pipes is relatively expensive in order to be able to clean them uniformly over the whole area.

task

On the basis of the prior art mentioned at the beginning, the invention is based on the object of the aforementioned To avoid at least some of the disadvantages and in particular to see a cleaning device for cleaning hoses that requires the hoses or pipes to be cleaned as automatically as possible without much effort from a user or worker.

invention

According to the invention, this is already achieved by the features of the independent claims. Preferred but not mandatory features are given in the independent claims.

In the simplest embodiment, this problem is solved by a hose cleaning device with a hose holder which is designed to move a hose to be cleaned, a hose cleaner, comprising at least one hose cleaner opening for passing the hose to be cleaned, at least one external brush assigned to the hose cleaner opening for cleaning a hose outside of the hose, at least one inner brush for cleaning the hose inside of the hose, a spray device for applying a cleaning liquid to the hose and a drive that moves the hose and pulls the hose through the hose cleaner opening of the hose cleaner.

The hose holder can also be referred to as a hose mover, since it has the function of moving the hose in relation to the stationary, ie immobile hose cleaner. This can be done in that the hose holder with the hose moves in relation to the hose cleaner or in that the hose holder is designed to move the hose in relation to the stationary hose cleaner and hose holder. In the first embodiment, the drive is designed to move the hose holder and in the second embodiment Approximately form the drive is provided in the stationary hose holder, which moves the hose.

The cleaning device is suitable for cleaning dimensionally stable and non-dimensionally stable hoses.

Dimensionally stable hoses, such as vacuum cleaner hoses, hold their hose shape independently and often have several ribs spaced from one another along the longitudinal axis, which is why these are also referred to as rib hoses. The embodiment for cleaning dimensionally stable hoses is referred to below as the dimensionally stable embodiment.

Hoses that are not dimensionally stable lose their shape when not in use, i.e. when relieved and when not clamped, and can therefore collapse, e.g. like an accordion. These hoses are often referred to as air distribution hose or air hose and often have a significantly larger diameter of 200 to 800 mm, preferably 500 mm. This embodiment for the cleaning of non-dimensionally stable hoses is referred to below as the non-dimensionally stable embodiment.

The non-dimensionally stable hose, that is to say air hose, preferably comprises in its hose jacket surface a stabilizing wire that rises in the shape of a helix in the jacket surface and which gives the air hose its desired geometry at least in diameter. The target geometry is thus specified in the cross section, but the air hose collapses in the longitudinal direction because the hose is otherwise made of a non-dimensionally stable, but preferably airtight and moisture-tight plastic.

The supply of the hose to be cleaned to the hose cleaner and then to the hose holder takes place axially ent long a centrally extending through these components System longitudinal axis. For the purposes of this invention, the longitudinal direction extends collinearly to this system longitudinal axis and the transverse direction extends transversely to the system longitudinal axis. The longitudinal axis of the system runs centrally through the hose cleaner and the hose holder.

This system longitudinal axis preferably extends vertically, so that the components of the cleaning device are arranged one above the other. However, it is also possible, especially if there is insufficient room height, to design the cleaning device in such a way that the system's longitudinal axis extends horizontally.

The hose cleaner preferably comprises a hose cleaner plate that extends in particular transversely to the system longitudinal axis, in particular designed as a steel plate, which defines a hose cleaner plane, which therefore preferably extends transversely to the system longitudinal axis. The at least one hose cleaner opening is formed in this hose cleaner plate, which can also be referred to in simplified form as a hose opening, but the name hose cleaner opening is more precise.

A hose cleaner housing can be formed around the hose cleaner, which prevents the cleaning liquid from splashing.

The hose cleaner preferably comprises an inner hose cleaner for cleaning the inside of the hose and an outer hose cleaner for cleaning the outside of the hose.

The inner hose cleaner is preferably designed as an inner brush which is arranged on a rotatable shaft and which can additionally be exposed to cleaning fluid, preferably by designing the shaft as a hollow shaft through which the cleaning fluid is supplied can.

The hose external cleaner is preferably designed as an outer ring surrounding the hose cleaner opening in the installed position or operating position for cleaning the hose, which has internal brushes on its inside that rest against the outside of the hose and clean it with it.

The brushes can either be continuous, that is to say extending over the entire circumference or only in segments or sections with individual brush sections that are circumferentially spaced from one another on the inner circumferential surface of the hose external cleaner.

The external hose cleaner is preferably also driven and designed in addition to the supply with a spray device, e.g. through holes in the outer jacket surface through which the cleaning fluid can be applied to the outer jacket surface of the hose.

Since brushes are preferably used for cleaning, the external hose cleaner is preferably designed as an external brush holder and the internal hose cleaner is preferably designed as an internal brush holder.

The hose cleaning device comprises two different embodiments, a first embodiment for cleaning dimensionally stable hoses and a second embodiment for cleaning non-dimensionally stable hoses.

The dimensionally stable embodiment is essentially characterized in that the hose holder is designed to releasably fix a first hose end and to pull the hose connected to the first hose end through the hose cleaner opening of the Hose cleaner.

In the preferred embodiment for the dimensionally stable embodiment, the hose holder comprises a releasable hose clamp, in which the front end of a hose to be cleaned can be clamped in such a way that the hose can be moved through the hose cleaner opening by moving the hose holder, in particular can be pulled through, but also can be moved back and forth if this is necessary.

In the non-dimensionally stable embodiment, the hose holder is designed more as a "hose winder" to pull the hose, in particular the air hose, through the hose cleaning device. which the hose assumes in the operating state to the hose cleaning device. In this respect, this embodiment of the hose cleaning device comprises a hose feed arranged on one side of the hose cleaner, which leads the hose to the hose cleaner in the target geometry and on the opposite side of the hose cleaner the hose holder with a Drive that pulls the air hose through the hose cleaner opening.

In the dimensionally stable embodiment, the hose holder is preferably designed to be movable in relation to the stationary, non-movable hose cleaner and the drive to move the hose holder relative to the stationary hose cleaner.

In the case of the non-dimensionally stable embodiment, both the hose holder and the hose cleaner are designed to be stationary, that is to say immobile. The drive inside the hose holder is designed to move the hose in relation to the stationary hose holder. For example the hose holder can have at least two wheels, belts or the like lying against one another with their circumferential surfaces or running surfaces, so that the air hose between them is guided against one another of the adjacent running surfaces centrally from the hose cleaner opening along the system longitudinal axis, namely running essentially parallel to the system longitudinal axis around this.

The air hose is thus fed in or introduced from an inlet end and, in particular in the case of the non-dimensionally stable embodiment, preferably comprises an annular hose feed at this inlet end in the geometry of the air hose in the state of use. This hose feed preferably comprises an inner ring and an outer ring concentrically surrounding this on the outside at a distance, so that the air hose is brought into its target geometry between the annular space formed by the inner ring and the outer ring. After exiting the feed, the air hose is fed into the hose cleaner opening, passes through this hose cleaner opening, is expanded in this hose cleaner opening, cleaned by the inner and outer brush and is fed to the drive of the hose holder, which pulls the hose further along the longitudinal axis of the system. In the direction of movement behind the hose cleaner, the air hose can then be folded up again and taken up there to save space. The air hose, i.e. the flexible hose, is folded up when it enters the feed, is pulled apart or stretched for cleaning in the hose cleaner, so that the inside and outside can be cleaned with the brushes in the hose cleaner, is driven by the drive inside the hose holder the hose cleaner and after being rubbed in the hose cleaner can be folded up again.

In the dimensionally stable embodiment, the hose feed is not absolutely necessary. The hose can simply be pulled through the hose cleaner from the hose holder.

In the non-dimensionally stable embodiment, the hose cleaner is stationary in relation to the hose holder during operation, so the hose holder does not move in relation to the stationary hose cleaner. Rather, the air hose is moved by the drive inside the hose holder and thus pulled through the hose cleaner.

For cleaning, maintenance and assembly, the hose cleaner in the non-dimensionally stable embodiment can be swiveled out of the folded operating position, in which the hose cleaner opening is aligned with the longitudinal axis of the system and is thus arranged coaxially with the hose holder, into an unfolded maintenance position. For this purpose, the hose cleaner is preferably attached to a laterally arranged swivel joint, which is offset from the system longitudinal axis and around which the hose cleaner with the hose cleaner opening can be swiveled sideways into a maintenance position for maintenance and assembly from the working position cursing with the system longitudinal axis.

For this purpose, the hose cleaner can be arranged in its own housing in the non-dimensionally stable embodiment, which is essentially teardrop-shaped in plan view, the swivel joint being arranged in the region of the apex of the housing and the hose cleaner opening in the lower, from the apex spaced round area is arranged, in which also sit the outer brushes, which preferably have a cover drive, for example a Belt or chain drive can be driven or driven.

In the dimensionally stable embodiment, one end of the hose to be cleaned is guided from below through the hose cleaner opening and attached to the movable hose holder with the upper end of the hose, that is to say the hose end, in particular a connection piece. Then the movable hose holder is moved in relation to the stationary hose cleaner in which the brushes for cleaning the hose are arranged.

To improve the cleaning performance, the hose holder can also move back and forth in the dimensionally stable embodiment.

At least one outer brush is preferably provided for cleaning the outside of the hose and at least one inner brush is provided for cleaning the inside of the hose.

The outer and inner brushes can rotate in the same direction or, which is useful to avoid twisting the hose, in opposite directions so that the brushes compensate for the forces acting on the hose and prevent rotation.

By means of the spray arrangement, a cleaning liquid is additionally applied or sprayed onto the hose in the area of the hose cleaner opening, which is preferably also carried out on the outside of the hose outside and on the inside on the inside of the hose. The application of the cleaning liquid can also be controlled separately from one another.

In the dimensionally stable embodiment, the hoses used in particular are those from vacuum cleaners or drying systems for floors, basements or the like, which are contaminated with mold, sponge or the like. The The invention also enables effective cleaning of such hoses or lines that are used in the food industry, but then with a corresponding cleaning fluid for such applications. In the execution form for cleaning dimensionally stable hoses, the hoses are designed with ribs. In addition to such ribbed hoses, however, air hoses that are not dimensionally stable can also be cleaned simply and effectively with the cleaning device according to the invention.

According to the invention, the dimensionally stable hoses can have hose diameters of any size, preferably a diameter of 20 to 50 mm, but also a diameter of up to 600 mm.

The non-rigid embodiment can be formed to air chläuche _S with a diameter of 200 mm to 800, preferably 500 mm to clean.

To do this, only the tools, i.e. the hose holder, the brushes and the spray device have to be replaced by correspondingly large components.

In the dimensionally stable embodiment with the movable hose holder, this preferably comprises at least one releasable hose clamp. This preferably has an inner hose push-on tube onto which the front end of the hose can be attached, as well as a hose holder outer connector that surrounds this hose connector on the outside, preferably circumferentially at a distance, so that between the inner hose connector tube and the outer hose holder outer connector there is an annular space for receiving the front end of the Hose is formed. When the hose clamp is open, i.e. when the hose holder outer socket is axially adjusted in relation to the stationary hose plug-on tube, in particular pulled up, the front end of the hose or the end connection stub is in this annular space. zens can be plugged in or can be slipped onto the hose tube.

After resetting the hose holder outer connector and thus releasing the spring tension, which pretensions when the hose holder outer connector is axially adjusted in relation to the hose attachment pipe, the hose holder outer connector surrounds the hose attachment pipe and thus forms the annular space for clamping the front end of the hose or the end of the hose.

For better fixation of the pipe or the end of the pipe in the annular space formed, a rib, a bead, a paragraph, a widening or the like can be provided on the outside of the hose holder plug-on pipe or on the inside of the hose holder outer connector.

For changing the hoses, the hose holder outer connector is designed to be adjustable or slidable along a common longitudinal axis in relation to the stationary hose attachment tube.

Preferably, when adjusting the hose holder outer socket in relation to the hose attachment tube, a spring is tensioned, which presses the hose holder outer socket into the rest position surrounding the hose attachment tube on the outside, in which the end of the tube is clamped in the annular space thus formed by means of the spring tension.

The hose holder outer connector is designed in particular to open when the hose holder comes into contact with the hose cleaner or a stop plate arranged shortly beforehand, in particular above it, and strikes against it. For this purpose, the hose holder outer connector preferably comprises a flange or stop which projects radially from the outer jacket surface and which, when the hose holder is retracted into the Hose cleaner strikes. This is preferably formed out at the rear end located in the insertion or joining direction.

The hose holder outer connector is preferably pre-tensioned by a compression spring, which presses the hose holder outer connector, in particular downwards in the closed position onto the hose holder attachment tube, and thus clamps the hose between the outer hose holder outer connector and the inner hose holder attachment tube. The hose clamp only opens when the spring force is overcome by pushing up the outer hose holder in relation to the hose attachment tube, e.g. when the hose holder above the hose cleaner moves into it.

The preferred embodiment comprises a stop plate arranged just above the hose cleaner with a passage opening for the hose holder outer connector. This passage opening is just so large that the outer surface of the hose holder outer connector can pass through it in the longitudinal direction, but the stop protruding radially from the outer surface at the rear end of the hose holder outer connector strikes the top against this passage opening and thus when the hose holder device is further lowered the hose clamp opens by pulling back the hose holder outer connector opposite the hose holder push-on tube.

The abovementioned stop plate into which the hose holder outer connector enters or against which it strikes is preferred as part of a changing device for the hose holder or hose holder changing device.

This hose holder changing device preferably comprises a stop plate extending transversely to the longitudinal axis of the system, i.e. to the longitudinal axis of the hose, with a stop plate opening provided therein which is adapted to the external diameter of the hose holder, in particular the hose holder outer connector. The outer circumferential surface of the hose holder outer connector can thus move into this stop plate opening, that is, penetrate the opening. The radially protruding collar or stop provided on the hose holder outer connector on the rear end of the hose holder outer connector in a joining direction cannot penetrate the stop plate opening and thus strikes the stop plate, so that when the hose is moved further axially along the system's longitudinal axis, the ratio of the hose holder plug-on pipe to open the hose holder outer connector and the hose holder against the force of the spring acting between the hose holder outer connector and the hose holder slip-on tube. The hose holder push-on pipe is thus moved in relation to the hose holder outer connector held by the stop plate and thus opens the annular space of the hose holder for changing the hose.

In a preferred embodiment, the stop plate has an elongated hole extending transversely to the system's longitudinal axis, which has a first section with a first diameter and a second section with a larger diameter than the first diameter. In this way, by transversely adjusting the stop plate of the hose holder changing device, an exchange of hose holders of different sizes with different large outer diameters, which are adapted to the opening diameters in the stop plate, can be changed. For this purpose, the hose holder outer connector only has to be moved into the stop plate and one hose holder can be exchanged for the other hose holder by changing the screws.

In the preferred embodiment, the outer brushes are not only on the hose cleaner as an inner brush within the Hose cleaner opening arranged, but additionally arranged on an outer brush holder, which is in particular designed as a hollow cylinder and has a hollow cylindrical Man telfläche, which connects to the hose cleaner opening or forms a ver elongated hose passage with the hose cleaner opening.

The outer brush holder is preferably arranged or inserted in an outer brush holder arrangement extending transversely to the longitudinal axis of the system. Particularly preferably, this external brush holder arrangement is designed as external brush holder plate, which extends transversely to the longitudinal direction of the system and which comprises at least one hose cleaning opening extending parallel or offset parallel to the longitudinal direction of the system.

In the particularly preferred embodiment, the outer brush holder is essentially designed as a hollow cylinder, which is designed to accommodate the outer brushes.

The outer brushes are particularly preferably releasably inserted into the outer brush holder, e.g. by means of insertion grooves formed on the inside along the longitudinal axis of the outer brush holder, into which complementary profiles engage on the outer ends of the outer brushes.

The outer brush can be designed along the entire circumference of the entire circumferential surface of the outer brush holder with brushes extending radially inward to the longitudinal axis of the system. It is also possible that several external brushes are circumferentially spaced apart from one another on the external brush holder, preferably spaced apart at regular intervals with radially inwardly projecting brushes.

In the embodiment for cleaning dimensionally stable hoses, in particular ribbed hoses, the inner brush is attached or attached to a lower end of a hollow inner tube. attachable. The upper end of this inner tube is received in a holder for the inner tube. To apply the cleaning fluid to the inside of the hose, the inner brush is preferably designed to apply or spray the cleaning fluid onto the inner bristles of the inner brush. The hollow inner tube supplies the inner brush with cleaning fluid, which exits through openings on the inner brush.

In the case of the non-dimensionally stable embodiment, however, the inner side of the hose is cleaned preferably from a side on which a hose feed is arranged. This is arranged along the longitudinal axis on the side of the hose cleaner opposite the hose holder, i.e. below the hose cleaner if the system longitudinal axis is arranged vertically. The hose feed is designed to convert the non-dimensionally stable air hose for the hose cleaner into its target geometry, i.e. to tension and stretch it so that the inner and outer surfaces are accessible for cleaning with the brushes. Preferably, the tube feeding is formed to an annular space with the diameter of the air _S chlauches for stabilizing the supply voltage in the Schlauchreinigeröff of the tube cleaner to be defined. The hose feed preferably comprises two concentrically arranged hollow cylinders, namely an inner hollow cylinder from which an outer hollow cylinder is arranged radially outwardly spaced, so that an annular space for guiding and shaping the air hose is gebil det between these two hollow cylinders.

A motor for driving the inner brush, which can preferably be extended from a retracted rest position into an extended cleaning position, in which the inner brush arranged on the driven shaft is located in the center of this hose feed, is preferably seated The hose cleaner opening level of the hose cleaner will be found or extended.

Particularly thorough cleaning can be achieved by driving the cleaning brushes, i.e. rotating them around or in the hose cleaner opening or close to it.

The particularly preferred embodiment provides that, in addition to the outer brush, the inner brush is also driven, preferably by a separate inner brush motor, which can preferably also be regulated separately from an outer brush motor. The drive is preferably via a shell drive, in particular a chain or belt drive.

In the dimensionally stable embodiment, the inner brush is arranged on an inner brush holder. This can, for example, comprise a plate or strut extending transversely to the longitudinal axis of the system, which is arranged at a distance from the hose cleaning device and from which the hollow inner tube for supplying the inner brush with cleaning fluid extends. In the case of a vertical design in which the system's longitudinal axis extends vertically, the inner brush holder is preferably arranged at the upper end at a vertical distance from the hose cleaning device.

The inner brush is preferably driven via an inner brush motor, which preferably drives an inner tube that is rotatably mounted in an outer tube. Before given, the storage takes place via a plurality of sliding bearings arranged axially in the longitudinal direction between the inner tube and the outer tube.

The outer and / or inner brushes can be arranged either in sections or over their entire circumference around the hose cleaner opening.

The brushes are preferably driven by one Motor, in particular designed as an electric motor. Separate motors are preferably provided for independently driving the inner and outer brushes. In addition, a separate height adjustment motor is preferably provided, with which the hose holder can be regulated separately from the other motors.

The transmission of the forces from the assigned motor to the rotating parts takes place preferably via gear wheels or casing drives, in particular chain drives.

The motors for the independent drive of the brushes (internal and external brushes) can preferably be regulated independently of a drive for adjusting the hose holder.

This drive for adjusting the height of the hose holder is preferably designed as an electric motor, which in particular adjusts the height of the relatively movable hose holder along the system's longitudinal axis via a rotating chain drive.

Preferably, the hose cleaner essentially comprises a hose cleaner plate which extends in a plane transverse to the system longitudinal axis of the cleaning device and in which the at least one hose cleaner opening is formed so as to extend in the longitudinal direction. The external brush holder is assigned to this hose cleaner opening. In a vertical embodiment, the outer brush holder is preferably formed above the hose cleaner opening.

In the embodiment for cleaning dimensionally stable hoses, the hose holder is also designed as a height-adjustable hose holder plate, which also extends with a plate plane transversely to the longitudinal axis of the system.

Finally, in the preferred embodiment, the at least one inner brush is on a separate from the outer brush brush and the hose holder formed plate angeord net, which extends transversely to the system longitudinal axis.

In the particularly preferred embodiment, the plates are designed as steel plates, for example with a material thickness of 20 mm and more. Because of the liquids, stainless steel can also be useful, at least in part.

The spray device is used to apply cleaning water with or without cleaning liquid to the hose in the area of the hose cleaner opening. The Spritzvorrich device is basically designed to bring a cleaning fluid onto and / or into the hose during cleaning or when it passes through the hose cleaner opening.

The spray device is preferably designed to apply the cleaning liquid to the outside and inside of the hose.

In the preferred embodiment, the Spritzvor direction comprises an annular, circumferentially closed spray ring or spray nozzle, the inner diameter of which is adapted to the hose cleaner opening, that is, surrounds it circumferentially in an installation position or connects to it. In the installed position, the splash ring therefore surrounds the hose cleaner opening in a ring shape and has one or more innensei term openings or nozzles through which the cleaning liquid is injected into the hose cleaner opening or can exit.

The spray device preferably comprises at least one water connection, in particular on the outside thereof.

Particularly preferred are four connections, which are each formed at 90 degrees to each other on the outer surface of each other ver. In the installed position, the splash ring sits in one position on the top of the hose cleaner around the hose cleaner opening. The splash ring is preferably designed as a plastic part.

The spray device preferably further comprises a plug-in connector with which it can be positioned in relation to the hose cleaner opening in such a way that it surrounds or encloses an area adjacent to the hose cleaner opening. For this purpose, a splash ring plate with a splash ring opening is preferably arranged just above the hose cleaner opening, the size of the splash ring opening being adapted to the hose cleaner opening and being aligned with the hose cleaner opening. The plug-in connector for fixing the splash ring can be inserted into this splash ring opening just above the hose cleaner opening and thus sits on the hose cleaner above the hose cleaner opening. The plug-in connector can thus be inserted into the hose cleaner opening, the splash ring protruding radially above the plug-in connector serving as a stop and thus resting on the top of the splash ring plate.

In the particularly preferred embodiment, the splash ring is designed as a plastic part and comprises the plug-in connector that is integrally connected to the splash ring.

To prevent water from escaping from the cleaning device, seals can be inserted between the splash ring and the hose cleaning opening, e.g. a ring seal or just grease.

The essential components of the cleaning device are preferably arranged on a common strut, in particular a longitudinal strut, which extends along the system's longitudinal axis and is particularly preferably designed as a T-beam or double-T-beam. At this point are the essentials System components arranged or fastened extending transversely to this system longitudinal axis.

The hose cleaner with the hose cleaner opening and the external brush assigned to it is arranged centrally along the longitudinal axis of the system.

The hose holder is arranged on a first side of the hose cleaner, which is either relatively movable in relation to the stationary hose cleaner for cleaning the dimensionally stable hose, in particular a ribbed hose, or a drive for pulling the non-dimensionally stable hose, in particular an air hose, through the hose cleaner opening the hose cleaner has.

The hose to be cleaned is fed to the hose cleaner opening of the hose cleaner from the side opposite or remote from the hose holder.

In the case of the non-dimensionally stable embodiment, the hose feed described above and the adjustable inner brush are arranged on this side.

In the dimensionally stable embodiment, the stationary hose cleaner with the at least one outer brush received therein and the at least one hose cleaner opening is arranged in the middle. In relation to the stationary hose cleaner, the movable hose holder, which is also referred to in simplified form as a "slide", can be adjusted in relation to the hose cleaner along the longitudinal axis of the system.

The drive for the adjustment preferably comprises at least one motor, preferably designed as an electric motor with a chain drive. Finally, the inner brush holder is arranged at the upper end, above half of the hose holder, of which the inner tube extends coaxially through the center of the Hose push-on connector extends into the hose cleaner opening of the hose cleaner. The hollow inner tube of the inner brush holder, the hose attachment tube of the hose holder and the hose cleaner opening of the hose cleaner thus extend coaxially along a common axis.

In the particularly preferred embodiment, the pipe cleaning device is designed to clean a plurality of hoses, in particular in the case of dimensionally stable embodiments. This is preferably done using several cleaning devices arranged next to one another, i.e. external brushes, internal brushes and spraying devices comprising several arrangements, e.g. four ribbed hoses at the same time.

The dimensionally stable embodiment can include an anti-twist device about the longitudinal axis to avoid twisting of the hose, which can occur in particular when the inner or outer brush exerts too great a torque on the hose and it thus rotates.

This anti-rotation device preferably comprises a safety plate which extends in a safety plane transversely to the longitudinal axis of the system and in each case has at least one safety plate opening for the passage of a hose to be secured against rotation. On the upper side of the locking plate opening of the locking plate in pairs and spaced apart pressure discs are provided on both sides, the non-rotatable on a drivable driven longitudinal shaft that extends parallel to the longitudinal axis of the locking plate. The pressure disks are designed in such a way that they rest with their radial circumferential surfaces on the outside of the hose and thus secure it against rotation. Such pressure washers arranged in pairs are arranged on both sides of the locking plate opening on the locking plate, so that each hose of a total of four rotating pressure washers against rotation is secured. The pressure washers are preferably made of a material with a high Reibungskoeffizien, especially rubber ..

For the passage of the hose and its fixation between tween each pressure disc pair of pressure discs arranged on a common drive shaft, an opening device is provided which is designed to lead two pressure discs of a pressure disc pair for the passage of a hose through the locking plate opening to be spaced from each other.

This opening device can, for example, comprise a height-adjustable lifting cylinder which extends perpendicular to the locking plate and is height-adjustable. Two arms protruding laterally from the longitudinal axis of the lifting cylinder can be pivoted to this lifting cylinder via an arm holder and engage with their free arm ends on actuating shafts which are rotatably mounted in bearing disks. The actuation shafts thus extend transversely to the longitudinal axis of the fuse plate over the fuse plate opening. At the actuation shafts extending transversely to the longitudinal axis of which are attached to pressure arms, which engage with their free ends in bearing blocks that are longitudinally displaceable on the driven longitudinal shafts. On an outer side of these bearing blocks facing away from the hose, a compression spring acts in each case and the inner side of the bearing brackets facing the hose rests against the respective pressure disk due to this spring tension. The bearing blocks thus press in the unactuated state of the opening device with their respective inner side against a pressure plate.

The springs press the pressure disks with their outer circumferential surfaces against the respective hose and thus secure it against rotation about its longitudinal axis. By lowering the lifting cylinder, however, the two pressure disks of a pair of pressure disks are pressed against the compression springs extending along the drive shafts and thus open the pressure disks of a pair of pressure disks for the passage of the hose.

In the case of the non-dimensionally stable embodiment for cleaning an air hose, cleaning can be improved and accelerated by connecting the upper end of the air hose to an air hose tensioner. This air hose tensioner is preferably designed as a hollow cylindrical ring body which is formed on a fastening end facing the hose for releasable attachment to the upper end of the air hose. The ring body is preferably widened conically at the fastening end, so that the air hose can be stretched over the conical widening and can be fixed with an attached clamping ring on the hose holder. During cleaning, this air hose tensioner is pulled as a dimensionally stable part through the hose cleaner opening of the hose cleaner and then through the pull-through device in the hose holder into the latter. After cleaning, the cleaned air hose with the air hose clamp can be removed from the hose holder, which can also be designed to accommodate the cleaned air hose and possibly the air hose clamp ner.

Accordingly, the first embodiment of the hose cleaning device shown in FIGS. 1 to 7 consists of a double-T-beam 2 seated on the floor, whose longitudinal axis defines the system longitudinal axis of the cleaning device, which is designed for cleaning dimensionally stable hoses extends vertically, one at the lower end of the double-T-beam 2 arranged stationary hose cleaner 4, one at the upper end of the double-T-beam 2 about 6 meters above the hose cleaner 4 arranged stationary inner brush holder 6 and one along the longitudinal axis of the double T-beam 2 height adjustable hose holder 8.

The hose cleaner 4, the inner brush holder 6 and the hose holder 8 thus comprise in this embodiment as steel plates extending transversely to the system longitudinal axis, on the front and transversely to the double T-beam 2, which preferably have a wall thickness of 20 mm.

In the present embodiment, the hose cleaning device is designed to clean four hoses with a diameter of about 20-50 mm next to one another. For the sake of clarity, only one device is shown and described before.

FIG. 3 shows an enlarged front view of the stationary hose cleaner 4. This comprises a hose cleaner plate 18 extending transversely to the system longitudinal axis, in which at least one hose cleaner opening 20 extending parallel to the system longitudinal axis is formed. Below each hose cleaner opening 20 a hollow cylindrical outer brush holder 22 is arranged, which rotates around a central axis of rotation with its outer surface around the respective hose cleaner opening 20.

According to the enlarged view in Figure 6, the outer brush holder 22 is designed as a hollow cylindrical shell body, which is attached to the underside of a sprocket 54, which in turn is rotatably mounted via a bearing 56 in the outer brush holder plate 18 of the hose cleaner 4.

On the inside of the outer brush holder 22, outer brushes are preferably attached at regular intervals spaced apart on the inner jacket surface, which have a complementary profile structure between the inner jacket surface of the bell 20 and the outer brushes so that they can be easily replaced by plugging them in.

An external brush motor 24 drives the chain via a chain wheel 54 and thus the outer brush holder 22 so that the water rotates around its longitudinal axis below the hose cleaning opening 22 around this to clean the outside of the hose.

According to the enlarged section VI from FIG. 3 in FIG. 6, a splash ring plate 48 is located just above the hose cleaner plate 18, in which a splash ring opening corresponding to the hose cleaner opening 20 within the hose cleaner plate 18 is formed.

Spray devices are inserted into this splash ring opening within the splash ring plate 48. The spray device is designed as a one-piece plastic part and comprises an annular spray ring 50, which protrudes radially beyond the respective spray ring opening in the splash ring plate 48, that is, rests on the top side and to which a sleeve-shaped plug-in connector 52 extends downwards and which, in the installed position, is on the top side engages in a sprocket 54 which is mounted in the hose cleaner plate 18 and is non-rotatably connected to the hohlzylindri's outer brush holder 22 at the lower end.

The splash ring has several connections 50a on the outside for the introduction of the cleaning liquid, which are injected downward via inside nozzles 50b into the splash ring and thus the hose cleaner opening 20 or the hose arranged in this.

The inner brush 14 is arranged centrally within the respective hose cleaner opening 20 in the outer brush holder plate 18, in each case at the lower end of a tube arrangement 12 comprising a rotatably driven inner tube 28, which is mounted in an outer tube 30 that surrounds it circumferentially.

Moving the hoses through the hose cleaner opening with the cleaning brushes arranged therein takes place via the height-adjustable, movable hose holder 8. To attach a hose, the hose holder 8 is first lowered down until it is just above the hose cleaner 4.

The hose holder includes hose clamps 38, each of which includes a hose push-on pipe 40 arranged around the pipe arrangement 12, onto which the front end of a hose can be pushed on the outside. This inner hose holder push-on pipe 40 is encased in its entirety by a hose holder outer connector 42, which is adjustable in height in relation to the hose holder push-on pipe 40 and is pressed down into the closed position via a spring (not shown) between the underside of the hose holder plate 44 and the upper end of this hose holder outer connector 42 . The hose holder outer connector 42 has at its upper end, that is to say at the rear end in the pulling direction, a radially outwardly protruding stop or collar 60, which against a stop bar 58 arranged above the splash ring plate 48 with a corresponding opening 62 for the hose holder outer connector 42 to pass through strikes and pulls the hose holder outer connector 42 counter to the pulling direction upwards against the compression spring, so that the hose clamp 38 is opened. In this way, a hose or a hose connector can be plugged onto the hose holder push-on pipe 40. As soon as the hose holder 8 moves upwards again in relation to the hose cleaner 4, the hose holder outer connector 42 is pushed down by the spring in relation to the hose holder plug-on pipe 40 and thus holds the hose between the hose holder plug-on pipe 40 and the hose holder outer connector 42 firmly.

After further hoses have been plugged onto the other hose holding devices of the hose holder, if necessary the hose holder 8 pulled up by the height adjustment motor 10, which in the present case also takes place via a Kettenan.

Each pipe arrangement 12 is mounted in a hose holder plate 38 of the hose holder 8 via a corresponding one of the slide bearing 36 within a corresponding through-opening.

According to FIG. 4, the hose holder 8 has a hose holder plate 38 extending transversely to the system longitudinal axis of the double-T-beam 2, through the plane of which the four pipe assemblies 12 extend in the corresponding slide bearings 36 ge leads.

The hose holder 8 is adjusted in height by means of the height adjustment motor 10 via a chain (not shown) driven trolley 46 in relation to the double T-beam 2, so that the hoses through the kor responding hose cleaner openings 20 of the hose cleaner 4 draw.

By rotating the brushes and spraying the hose with cleaning fluid through the spray device, the hose is cleaned particularly effectively.

Fig. 5 shows an enlarged front view of the inner brush holder 6 at the upper end of the double-T support 2 for driving the inner brush 14 within the hose cleaner 4. This also includes a transverse to the system longitudinal axis extending and stationary at the upper end of the double-T -Carrier 2 attached inner brush holder plate 32, which defines an inner brush plate plane extending transversely to the double T-carrier 2. In this inner brush plate plane is an opening in which the tube assembly 12 is received. The pipe assembly 12 is held at its upper end by a plate-shaped rotary leadthrough 34, which is at the top in the Inner brush holder plate 32 is mounted via a bearing 62.

The rotary feedthrough 34 is rotated on the inner brush plate 32 around the downwardly extending Rohran order 12 via a chain from the inner brush motor.

The inner tube 28 of the tube arrangement 12 extends upwards over the rotary leadthrough 34 into a connection socket in a connection plate 64, which can be supplied with cleaning fluid via a feed line (not shown). The cleaning liquid is thus conducted via the hollow inner tube 28 to the inner brush 14 and emerges from holes in it.

The inner brushes 14 are arranged in the center of the respective hose cleaner opening 20 of the Außenbürstenhalterplat te 18 in the installed position and thus clean the respective hoses when moving the hose in the pipe opening by means of the movable hose holder.

To cancel the torques, it has been found to be particularly useful that the outer brushes and inner brushes rotate in opposite directions.

In FIGS. 1 and 2, the changing device for the hose holder or the hose holder changing device 110 can also be seen, which is arranged extending transversely to the system longitudinal axis L just above the hose cleaner 4.

As can be seen here, this hose holder changing device 110 also comprises a stop plate 112 extending transversely to the system's longitudinal axis L, which extends centrally along the double-T beam 2, which stop plate openings 114 for the passages of the hoses and hose holders 8 having.

These stop plate openings 114 are designed as elongated holes and have a left-hand side in the figures section of smaller diameter and a section of larger diameter on the right-hand side in the figures. Thus, by moving the stop plate 112 transversely to the longitudinal axis of the system, the stop plate can be adapted to hose clamps 38 of different sizes with differently sized outer diameters adapted to the sections of the elongated hole. When the hose clamps 38 are lowered, the radially protruding, flange-like stop 60 at the rear end strikes the corresponding edge of the stop plate opening 114 and thus pulls the hose holder outer connector 42 of the hose clamp 38 up in relation to the stationary hose holder push-on pipe 40, so that the hose holder 38 opens and the hose can be changed.

FIGS. 7A-7D show the optional anti-twist device 66 to prevent the hoses from rotating and twisting about their respective longitudinal axes during cleaning. The anti-rotation lock 66 comprises a locking plate 67 which extends in a locking plate plane transversely to the system longitudinal axis L and in each case has at least one locking plate opening for the passage of a hose 69 to be locked against rotation. On the upper side of the locking plate opening 68 of the locking plate in pairs and spaced apart pressure discs 71, 72 are provided on both sides of the locking plate opening, which sit non-rotatably on a driven longitudinal shaft 73 which extends parallel to the longitudinal axis of the locking plate. The pressure disks 71, 72 are designed in such a way that their radial circumferential surfaces rest on the outside of the hose 69 and thus secure it against rotation. Such pressure disks 71, 72 arranged in pairs are arranged on both sides of the locking plate opening on the locking plate 67, so that each hose 68 is secured against rotation by a total of four co-rotating pressure disks 71, 72, i.e. two pairs of pressure disks. The pressure washers 71, 72 are preferably made of a material with a high friction Exercise coefficients exist, especially rubber.

To guide the hose 68 through and fix it between each pressure disc pair of pressure discs 71, 72 arranged on a common longitudinal shaft, an opening device is provided which is designed to hold the pressure discs 71, 72 of a pressure disc pair for the passage of a hose 69 through the locking plate opening 68 to be spaced from each other.

This opening device can, for example, comprise a height-adjustable lifting cylinder 74 which extends perpendicular to the plane of the securing plate on the securing plate 67. On this lifting cylinder 74, two arms 75a, 75b protruding laterally from the longitudinal axis of the lifting cylinder 74 can be rotatably articulated via an arm holder 75 and engage with their free arm ends on actuating shafts 76a, 76b which are in bearing washers 78, 79 on the upper side of the securing plate 67 are rotatably mounted. The actuating shafts 76a, 76b thus extend transversely to the longitudinal axis of the securing plate over the securing plate opening 68. On the actuating shafts 76a, 76b, pressure arms 80, 81 are attached extending transversely to their longitudinal axis, which engage with their free ends in bearing blocks 82, 83, which sit longitudinally on the driven longitudinal shafts 73. On an outer side of these bearing blocks 82, 83 facing away from the respective hose 68, a compression spring 84, 85 acts in each case and the inside of the bearing blocks 82, 83 facing the respective hose 68 is due to this spring tension against the respective, longitudinally lockable with the bearing blocks 82, 83 connected pressure washer 71, 72. The bearing blocks 82, 83 thus press the pressure disks 71, 72 of a pair of pressure disks against each other and thus against the jacket surface of the hose 69 due to the spring tension in the unactuated state of the opening device.

When the lifting cylinder 74 is raised, the pressure disks are located 71, 72 with their outer circumferential surfaces against the respective hose 69 thus secure it against rotation about its longitudinal axis, as shown in the three hoses 69 from right to left in FIGS. 7A to 7D. By lowering the lifting cylinder 74, as shown on the left in FIGS. 7A-7D, however, the two pressure disks 71, 72 of a pair of pressure disks are pressed against the compression springs 84, 85 extending along the longitudinal shaft 73 and thus open the pair of pressure disks for the passage of the hose 69.

In Figures 7A-7D, as in Figures 1 to 6, a hose cleaning device for cleaning 4 Rip pen hoses is shown side by side, but this is not mandatory. Figures 8 to 14 show the isometric views and front views in half section of an air hose cleaning device Reinigungsvor direction according to the second embodiment, which thus not dimensionally stable for the cleaning of elastic air chläuchen _S is formed. This in turn comprises a system longitudinal axis L, which also extends vertically in this embodiment.

FIGS. 8 to 14 show the functional sequence when cleaning an air hose. These figures each include two figures, the first figure with the addition A in isometric view and a second figure with the addition B of the front view in half section. In the figures, the front Konstruktionspro fil is removed in the respective isometric view to allow insight into the cleaning device. However, this is only done for better understanding and not on the actual system.

The hose cleaning device is arranged in a frame constructed from construction profiles 116, 117, which surrounds and accommodates them, the construction profiles 116, 117 extending horizontally and vertically. are connected to each other at the corners so that a cabinet-like receiving frame for the cleaning device is formed.

Approximately in the middle between the profile frame base and the profile frame roof, a horizontal plane 118 is drawn in through construction profiles 116, in which a vertically mounted inner brush shaft 97 driven by an inner brush motor 96 is arranged.

Above the horizontal plane 118, a support plate 120 is attached to the inner brush shaft 97, on which a collapsed air hose 122 rests.

In the air hose 122 running in the longitudinal direction in the outer jacket surface, a helically rising stabilization wire is embedded, which gives the otherwise air- and / or moisture-tight material air hose certain stability and a certain external geometry in the size of this stabilization wire. The retracted stabilization wire is preferred, but not mandatory, that is, optional

On the inside of the support plate 120, a removable inner tube 124 is arranged, which forms the smallest inner diameter of the stabilizing wire when the air hose 122 is completely wound together. The platen 120 is rotatably supported by a hollow shaft motor 126 around the inner brush shaft 97 in an inner brush 128 on the horizontal plane 118 len.

From the top of the receiving frame extends coaxially to the longitudinal axis of the inner brush shaft 97, a length-adjustable centering tube 130 which centers the inner brush shaft 97 on the upper side in the cleaning position. To the side of this centering tube 130 are arranged equally spaced from ceiling frames 132, which are attached to their lower end in the installed position, each with a belt conveyor 134, each with three rollers arranged vertically one above the other, which are enclosed by a rubber band and which are driven.

The pivotable outer hose cleaner 136 is fastened laterally to a vertical structural profile and has a pivot pin 104 at one end, around which the two longitudinally spaced plates 136a, 136 of the outer hose cleaner 136 are rotatably mounted. In the outer hose cleaner 136, the hose cleaner opening, which are formed in the form of two circular and coaxial holes penetrating through the spaced plates in the vertical direction. The annular outer brush holder 138, which is rotatably driven by an outer brush motor 140, is arranged between the two plates of the outer hose cleaner 136. On the inner circumferential surface of the outer brush holder 138, outer brushes 141 protruding inwardly and spaced apart at regular intervals from one another are pushed on the inner circumferential surface.

The outer tube cleaner 136 is thus tellung from the position shown in Figures 8-11 Rüst _S, in which it is pivoted out of the interior of the receiving frame, pivoted to the position shown in Figures 12-14 cleaning position, in which the longitudinal axis cleaner mouth through the tube is aligned with the longitudinal axis of the inner brush shaft and the centering tube 130.

In the course of cleaning, a funnel 144 designed to accommodate the inner brushes is placed on the upper side of the air hose 122 placed on the support plate 120, the outer diameter of which corresponds to the nominal diameter (diameter in use) of the air hose 122. This funnel 144 has an upper hollow cylindrical section 144a, to which a lower, conically inwardly tapering outlet Section 144b connects, which can be detachably connected to the inner tube 124, for example via a bayonet lock. The inner brush head 146 can be inserted into this hollow cylindrical funnel 144 and can be connected to the inner brush shaft 97 in a rotationally fixed manner.

The inner brush head 146 is an essentially cylindrical body, which has a plurality of equidistantly spaced slots in its outer lateral surface, into which brush strips 148 protruding radially outward can be inserted.

According to FIGS. 11A, 11b, a likewise hollow-cylindrical air hose tensioner 150 is placed on the upper side of the air hose 122 and, in the installed position, encloses the inner brush head 146 on the outside at a certain distance.

The air hose tensioner 150 is slightly widened at the lower fastening end facing the air hose 122, so that the upper end of the air hose 122 can be pulled over this edge formed in this way. A clamping ring pulled over the top of the air hose tensioner 150 sits on this shoulder formed by the conicity and clamps the air hose 122 with the air hose tensioner 150. Thus, the air hose tensioner 150 can be raised to stretch the air hose 122.

Combined with the inner brush motor 96 is a lifting cylinder 142, which can raise the support plate 120 with the inner brush shaft and the air hose 122 from the lowered set-up position (FIGS. 8-12) to the raised cleaning position (FIGS. 12-14), in which the inner brushes are located holder is at the same height as the outer brush holder 136 or the outer hose cleaner.

The functional sequence for cleaning an air hose 122 is described below with reference to FIGS. 8-14.

According to FIG. 8, the folded air hose 122 is opened the support plate 120 is placed and an inner tube 124 adapted to the size of the air hose 122 is connected to the support plate 120 in a rotationally fixed manner.

According to FIG. 9, the funnel 144 is then placed on the inner tube 124 and also connected to it in a rotationally fixed manner.

According to FIG. 10, the inner brush head 146 is inserted into the funnel 144 and connected to the inner brush shaft 97 in a rotationally fixed manner.

Then, according to FIG. 11, the air hose tensioner 150 is placed circumferentially around the inner brush head 146 on the air hose 122 and connected to the upper end of the air hose 122 via the clamping ring (not shown) pushed onto this air hose tensioner 150 on the outside.

The outer hose cleaner 136 is then pivoted from the set-up position shown in FIGS. 8-11 into the cleaning position shown in FIGS. 12-14, in which the hose cleaner opening in the outer hose cleaner 136 coincides centrally with the system longitudinal axis, which extends along the inner brush shaft 97 and of the centering tube 130 extends.

In FIG. 13, the lifting cylinder 142 is raised so that the inner brush head 146 is in the raised cleaning position in which it is on a plane with the outer brush holder 138.

In this position, the centering tube 103 is also lowered into the upper side of the inner brush head 146 and centers it.

Then, as shown in FIG. 13, the hose holder 150 is lifted and pushed into the two belt conveyors 136, which first pulls the hose holder 150 and then the air hose 122 through the hose cleaner opening and, in doing so, by rotating the inner brush head 146 and the outer Outer brush holder 138 and wetting with the cleaning fluid cleans. Preferably, the inner brush and the outer brush rotate in opposite directions in order to reduce the shear forces.

FIG. 14 finally shows the air hose 122 after cleaning, in which it is received together with the air hose tensioner 150 on the top side in the ceiling frame 132. By opening the ceiling frame 132 and moving the belt conveyor 134 apart, the cleaned air hose 122 with the air hose tensioner 150 can then be removed from the ceiling frame 132 after the outer hose cleaner 136 has been unfolded into the set-up position and the inner brush head 146 with the inner brush shaft 97 of the lifting cylinder 142 was lowered again.

In the embodiment, for non-dimensionally stable air _S chläuche below is a tube feeding, vertically above and laterally swung out before preferably the outer tube cleaner or cleaner hose and over the tube holder. The outer hose cleaner and hose holder are stationary, so they cannot be moved. Instead, a pull-through device is provided in the hose holder, which is designed to pull the air hose through the hose cleaner.

The pull-through device preferably comprises a roller or belt conveyor that rotates around driven roller axes with circumferential roller running surfaces, the rollers of a roller pair being arranged so that the roller running surfaces lie against one another or roll against one another and on which circumferential rubber bands are arranged. Thus, an air hose inserted between the roller running surfaces of the roller pairs is pulled up through the rotation of the belts into the ceiling frame 132 serving as a hose collecting space above the two pull-through devices designed as belt conveyors 134. Preferably includes each belt conveyor 134 pairs a plurality of rollers arranged offset parallel to the system longitudinal axis L and arranged one above the other.
