Description

[0001] The invention relates to a cleaning device for cleaning a production pallet for the construction industry, comprising at least one brush with a longitudinal extension and at least one drive device for moving the at least one brush. Furthermore, the invention relates to a production plant for manufacturing precast concrete components for the construction industry, comprising at least one such cleaning device, and to a method for cleaning a production pallet for the construction industry using at least one such cleaning device.

[0002] Traditionally, production pallets are cleaned of contaminants manually. Heavy, inflexible, expensive, and difficult-to-maintain drum brushes or rotating horizontal brushes are already known. While these can generally be used for pre-cleaning production pallets, they sometimes lack sufficient cleaning efficiency to ensure high-quality precast concrete components without requiring post-processing steps on the production pallet.

[0003] Such a cleaning device is already known from document EP 2 463 034 B1, wherein concrete residues are rubbed off the production pallet by a disc brush in the form of a vertical brush with a rotational movement about an axis oriented perpendicular to the surface of the production pallet to be cleaned.

[0004] A disadvantage of the state of the art is that, while disc brushes or vertical brushes offer greater cleaning performance than horizontal brushes, they are expensive and require a lot of space, requiring a large number of components to clean the pallet. Furthermore, the cleaning procedure cannot be practically adapted to changing dimensions of the production pallet or to a range of production pallet dimensions. A multiplication of disc brushes requires a separate drive for each disc brush. The disc brushes, which already have a large diameter, must be offset in the transport direction of the production pallet and arranged overlappingly across the width of the production pallet for proper cleaning to ensure adequate removal of concrete residue.In addition, maintenance work is difficult due to the complex structure, and both the provision and assembly of the cleaning system as well as the maintenance measures for the brushes as wearing parts are associated with a high level of effort and high costs.

[0005] The objective technical problem of the present invention is therefore to provide a cleaning device which is improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, and which is characterized in particular by a particularly simple and compact structural design with a low number of required components, which, due to the low complexity, can be flexibly adapted to the respective requirements of the cleaning device at low cost and low effort, has a long running time and / or is easy to maintain.

[0006] This problem is solved by the features of claim 1.

[0007] It is therefore provided according to the invention that the at least one brush can be moved in an oscillating manner along the longitudinal extent by the at least one drive device.

[0008] This makes it possible to provide a cleaning device for a given width of the production pallet (orthogonal to the transport direction of the production pallet), which on the one hand has a particularly small width (orthogonal to the longitudinal extent) and yet effectively cleans the entire width of the production pallet and on the other hand is efficiently adjustable in the longitudinal extent - without duplication of expensive and complex disc brushes with their own drive device.

[0009] Furthermore, the oscillating movement trajectory of at least one brush enables a particularly high cleaning performance to be generated.

[0010] Another positive feature is that the cleaning device is inexpensive to manufacture, easy to assemble, and user-friendly to maintain - for example, if at least one brush needs to be replaced.

[0011] Particularly preferably, the at least one brush is cuboid-shaped with a longitudinal direction along the longitudinal extent in which the oscillating movement is generated by the at least one drive device. In general, it is arbitrary whether a single brush or a combination of a plurality of brush segments is provided for a common brush.

[0012] In addition, it can be guaranteed that proper cleaning in the sense of removing concrete residues or other contaminants on the production pallet is achieved purely mechanically without the addition of additives.

[0013] In addition, the at least one brush and / or the components of the cleaning device that are movable for removing or loosening contaminants can be designed with low mass, so that an energy-efficient cleaning device can be ensured.

[0014] As stated at the outset, protection is also sought for a production plant for producing precast concrete components for the construction industry with at least one cleaning device according to at least one of the preceding claims and at least one production pallet for the construction industry, wherein the production plant comprises a drive unit for the relative movement of the at least one production pallet with respect to the at least one cleaning device, wherein it is preferably provided that the longitudinal extent corresponds to at least 70%, particularly preferably at least 85%, of a width of the at least one production pallet orthogonal to a transport direction of the at least one production pallet.

[0015] In general, the relative movement can involve a displacement of the production pallet relative to a stationary cleaning device or vice versa.

[0016] For example, a control or regulating device can be provided for the cleaning device, which is configured to control the at least one drive device for transmitting the oscillation movement to the at least one brush. For example, it can be provided that the oscillation frequency and / or the oscillation amplitude is adjusted—optionally depending on the transport speed of the at least one production pallet relative to the at least one cleaning device.

[0017] The longitudinal extent of the at least one brush can essentially correspond to the width of the at least one production pallet – possibly minus any edge formwork on the at least one production pallet and / or the dimensions of any side brushes for the edge formwork of the at least one cleaning device. The abrasion is thus not limited to locally confined cleaning areas – as is the case, for example, with the disc washers used in the prior art.

[0018] As stated at the outset, protection is also sought for a method for cleaning a production pallet for the construction industry by at least one such cleaning device, wherein the following process steps are carried out: the production pallet is moved relative to the at least one cleaning device in a transport direction; in the course of the relative movement, the at least one brush is moved orthogonally to the transport direction by the at least one drive device for cleaning the production pallet

[0019] In general, the production pallet or the cleaning device can remain stationary during the cleaning process, although movement of both the production pallet and the cleaning device is also conceivable.

[0020] Preferably, a feed speed of the production pallet (or the cleaning device) is in the range of 5 m / min to 20 m / min, particularly preferably between 10 m / min and 15 m / min.

[0021] The invention is not limited to a specific number of component parts, whereby device features - for example the mounting situation of the at least one brush or the transmission of the force application from the at least one drive device via the eccentric unit described below - can be used in the process flow of the method.

[0022] Advantageous embodiments of the invention are defined in the dependent claims.

[0023] According to an advantageous embodiment of the invention, it is provided that the at least one brush is of metallic design, preferably in the form of a steel brush, or in the form of a plastic brush and / or the extension of the at least one brush along the longitudinal extent is greater than a width and / or height of the at least one brush, wherein it is preferably provided that the extension of the longitudinal extent is at least 1 m, particularly preferably at least 2 m or 5 m.

[0024] A metal brush provides a particularly long service life. With a length of more than 1 m, comprehensive cleaning can be achieved by abrasion of concrete residue or other contaminants on the production pallet. However, a felt layer, plastic layer, or similar material can also be used as a brush, particularly under increased contact pressure.

[0025] Typical widths for production pallets in the context of the present invention are in the range of 3 m to 4 m – preferably approximately 3.5 m – although production pallets up to 8 m wide can also be provided. The cleaning device can be adapted accordingly to the existing width of the production pallet by adding or removing brush segments – for example, by screwing brush segments on or off. The at least one brush is generally somewhat shorter in its longitudinal extent than the width of the production pallet – for example, in the range of 1 m to 5 m, depending on the dimensions of the production pallet.

[0026] Preferably, the at least one brush with a longitudinal extension of at least 1 m comprises a plurality of brush segments - particularly preferably with a longitudinal extension in the range between 200 mm and 400 mm.

[0027] Advantageously, it is provided that the at least one brush is arranged on a portal or a cantilever arm and / or is arranged on a profile rail that is displaceably guided on the portal or the cantilever arm, wherein it is preferably provided that the longitudinal extent of the at least one brush extends substantially over an entire longitudinal extent of the profile rail.

[0028] The cantilever arm is designed to be wide enough to encompass, for example, a stationary boom of a machine frame or a movable robot arm. The profile rail can, for example, be U-shaped to accommodate and secure the at least one brush within the profile, or it can be a flat profile for screwing the at least one brush onto. The geometry or shape of the profile rail is generally arbitrary and primarily serves to transmit the oscillating movement from the at least one drive device to the plurality of bristles and / or brush sections.

[0029] The portal or cantilever can be stationary or movable.

[0030] The connection of the at least one brush is generally arbitrary, whereby, for example, a screw connection of the at least one brush to a beam can be provided as a profile rail.

[0031] The profile rail is preferably guided linearly via a plain bearing and driven by a motor.

[0032] It has proven advantageous that the cleaning device comprises a scraper for cleaning the production pallet and / or a side brush for cleaning an edge formwork arranged on the production pallet and / or a stationary brush for collecting contaminants arranged on the production pallet, wherein it is preferably provided that the scraper, the side brush and / or the stationary brush are arranged on a common base body.

[0033] For example, a concrete wall element and the associated formwork elements are removed from the production pallet, which is then maneuvered to the cleaning device. The scraper on the front edge of the production pallet can be pressed onto the production pallet to remove coarse contaminants. During the cleaning process, concrete residues can be loosened and pushed off the production pallet by the cleaning device. The stationary brush can act as a collecting device or hopper for a collecting container or suction system.

[0034] According to an advantageous embodiment of the present invention, it is provided that the at least one drive device is coupled to the at least one brush in such a way that a rotational movement of the at least one drive device can be converted into a translational movement of the at least one brush along the longitudinal extent and / or comprises an eccentric unit for moving the at least one brush along the longitudinal extent of the at least one brush and / or imparts an oscillation frequency in the range between 5 Hz and 0.1 Hz, preferably between 2 Hz and 0.5 Hz, to the at least one brush.

[0035] Oscillation amplitudes are preferably in the range between + / - 2 mm and + / - 300 mm, particularly preferably in the range between 3 mm and 12 mm.

[0036] For example, the translational oscillation movement can be transmitted via a lever arranged on the drive device or on the eccentric unit.

[0037] Particularly preferably, the transmission of movement between the at least one drive device (e.g., an electric motor) and the profile rail (e.g., a beam) is effected by means of a crank mechanism. The crank mechanism can comprise the eccentric unit.

[0038] Preferably, the oscillation amplitude can be adjusted in conjunction with the at least one brush on the eccentric unit—for example, by shifting a force application point, a lever length, and / or a connection point of the eccentric unit to the at least one drive device in the radial direction around the rotational axis of the at least one drive device. According to a preferred structural design of the eccentric unit, bores are provided with which—initiated by a rotational movement of the drive shaft of the at least one drive device—varying strokes for the at least one brush can be realized.

[0039] Preferably, the at least one drive device—particularly preferably the eccentric unit—comprises a cam disk in order to be able to realize varying speeds at a fixed speed of a motor of the at least one drive device. For example, a speed is increased or decreased at a reversal point in the oscillating drive of the at least one brush. A cam disk allows for particularly favorable adjustment of the imparted oscillation speed, for example, a speed vector pointing in the translation direction along the longitudinal extension of the at least one brush being adjusted at a predefined speed.

[0040] However, an eccentric unit is generally not absolutely necessary, whereby the oscillating movement of the at least one brush can be generated, for example, by a linear drive with alternating force application to the at least one brush (for example alternating push and pull movements).

[0041] For example, the at least one drive device can comprise at least one pneumatically or hydraulically driven cylinder, with which the at least one brush is driven in an oscillating manner. For example, the drive can be exclusively translational.

[0042] It has proven advantageous that exactly one drive device is provided for oscillating the at least one brush and / or a lifting motor is provided with which the at least one brush can be moved in the use position of the cleaning device in the vertical direction relative to the production pallet.

[0043] An advantageous aspect of the oscillating cleaning mechanism is the particularly efficient use of a single drive device for a large number of brushes (for example, arranged in sequentially cleaning rows). However, a duplication of the brush drives is not necessary, as is the case with conventional disc brushes.

[0044] Particularly preferably, the cleaning device is mounted on a height-adjustable frame in order to be able to adjust or control a contact force or contact pressure of the at least one brush on the production pallet, whereby the cleaning performance can be influenced.

[0045] An advantageous variant consists in that a width of the at least one brush is in the range between 5 cm and 30 cm, preferably between 6 cm and 12 cm.

[0046] This means that the installation space of the cleaning device - which, for example, had to be reserved for the circumference of the disc brushes in the prior art - can be used for other purposes or reduced.

[0047] It is preferably provided that at least one further brush can be added to the at least one brush in a modular manner to increase the longitudinal extent and / or at least one brush of a plurality of brushes of the at least one brush can be removed to reduce the longitudinal extent, wherein it is preferably provided that the at least one brush is arranged on the cleaning device in an exchangeable manner for maintenance or cleaning purposes.

[0048] For example, the at least one brush can be secured to a beam or profile rail by a screw connection, allowing a desired number and / or type of brushes, brush sections, or brush segments to be connected depending on the requirements of the cleaning device or the dimensions of the production pallet to be cleaned. For example, this allows a change in the material type for the at least one brush to be carried out particularly quickly, preventing or shortening a production stoppage.

[0049] In one embodiment of the invention, it is provided that the at least one brush is mounted on the cleaning device in a floating manner, preferably on plastic or rubber, and / or resiliently and / or on an air cushion, preferably arranged within a hose, wherein it is preferably provided that the cleaning device comprises a profile rail and the floating and / or resilient mounting and / or the mounting on the air cushion is located between the at least one brush and the profile rail.

[0050] A floating bearing can be defined as a bearing on an elastic and / or flexible material, for example, whereby manufacturing tolerances, unevenness or irregularities in the impurities can be compensated.

[0051] Particularly preferably, the bearing serves a dual function for a vertical lift of the at least one brush and for elastic compensation with respect to the substrate. This can be achieved, for example, by a bearing on the air cushion. For example, the air pressure in a hose can be adjusted in order to adjust the vertical positioning of the at least one brush relative to the production pallet and / or the bearing conditions when the cleaning device is in use. An energy accumulator - for example a spring - can be used to reset the at least one brush when the air pressure is reduced or increased. In addition, the bearing can influence the contact pressure.

[0052] The force with which the at least one brush is pressed onto the production pallet for cleaning can generally be determined by its own weight. The contact pressure can preferably be set via a height-adjustable frame, the gantry or the cantilever arm and adjusted - if necessary continuously and / or during the cleaning process. Adjusting the contact pressure via the force application mediated by the at least one drive device is generally conceivable as an alternative or in addition. Adjusting the force application in the vertical direction onto the production pallet corresponds to a degree of abrasion removal of concrete residues or contaminants on the production pallet. A grinding process can generally be provided additionally, but is not required.

[0053] According to a preferred embodiment of the invention, it is provided that the cleaning device comprises at least two, preferably parallel, rows of the at least one brush, which are arranged orthogonally to the longitudinal extent one behind the other, preferably with spatial spacing between the at least two rows.

[0054] This can result in particularly favorable cleaning results. For example, if a contaminant is accidentally missed by the first row of brushes or the brush itself during the oscillation process, it can be loosened and removed by the subsequent row of brushes or the brush itself.

[0055] Furthermore, it is preferably provided that the at least two rows are driven by the same drive device, preferably via the same eccentric unit that may be present.

[0056] This allows the drive device to be used particularly efficiently for effective cleaning.

[0057] In a further embodiment, it can be provided that an oscillation movement of the at least two rows is coupled in such a way that the at least two rows oscillate in opposite directions or alternately.

[0058] With an oscillating movement of the brush rows in opposite directions - or, in the case of at least three rows, alternating - vibrations of the cleaning device and the production pallet are reduced and the removal of contamination is promoted.

[0059] According to an advantageous embodiment of the invention, it is provided that the production plant is designed in the form of a circulation system for the at least one production pallet, wherein one station of the circulation system for the automated placement of formwork elements on the at least one production pallet and / or for the automated application of liquid concrete onto the at least one production pallet and / or for the automated placement of reinforcement elements onto the at least one production pallet and / or for the automated placement of a precast concrete component onto the at least one production pallet and / or for the automated cleaning of the at least one production pallet by the at least one cleaning device is intended.

[0060] At least one cleaning device can be integrated into an efficient value chain for the production of precast concrete components in a space-saving manner.

[0061] Further details and advantages of the present invention are explained in more detail below with reference to the exemplary embodiments shown in the drawings.

[0062] Fig. 1 shows a cleaning device 1 for a production plant for the manufacture of precast concrete components for the construction industry with a production pallet 2 for the construction industry.

[0063] The production system comprises a drive unit (not shown for reasons of clarity) for the relative movement of the production pallet 2 with respect to the cleaning device 1.

[0064] The production facility is in the form of a circulation system for the production pallet 2. The circulation system comprises a station for the automated placement of formwork elements, a station for the automated application of liquid concrete, a station for the automated placement of reinforcement elements, a station for the automated placement of a precast concrete component onto the production pallet 2, and a station for the automated cleaning of the production pallet 2 by the cleaning device 1. The station for the automated cleaning of the production pallet 2 is shown.

[0065] The cleaning device 1 for cleaning the production pallet 2 comprises a brush 3 - composed of segments - with a longitudinal extension 4 (parallel to a width 24 of the production pallet 2 and orthogonal to a transport direction 25 of the production pallet 2) and a drive device 5 for moving the brush 3. The brush 3 is moved in an oscillating manner along the longitudinal extension 4 by the drive device 5 in order to remove contaminants from the surface of the production pallet 2 or to loosen them for subsequent collection in a collecting container or suction.

[0066] In the process of cleaning the production pallet 2 via the cleaning device 1, the production pallet 2 is moved relative to the cleaning device 1 in the transport direction 25 and in the course of the relative movement, the brush 3 is moved in an oscillating manner orthogonal to the transport direction 25 by the drive device 5 for cleaning the production pallet 2.

[0067] The cleaning device 1 comprises a scraper 11 for pre-cleaning the production pallet 2 in the sense of a rough cleaning by loosening concrete residues - for example, by breaking them away using a brass or plastic scraper. In general, the cleaning device 1 comprises at least one - preferably two - side brushes for cleaning one (preferably two) edge formwork 13 arranged on the production pallet 2 and a stationary brush for collecting contaminants arranged on the production pallet 2 (not shown for reasons of clarity). The scraper 11, the side brush, and the stationary brush are generally arranged on a common base body 15, wherein the side brush is arranged laterally on the base body with respect to the transport direction 25 and the stationary brush is arranged behind the brush 3 on the base body.

[0068] The brush 3 is arranged on a portal 8, whereby in general an arrangement on a cantilever arm or robot gripper arm can alternatively be provided.

[0069] Fig. 2 shows that the brush 3 and the drive device 5 are arranged on a height-adjustable frame 29 so that, when the brush is displaced (or tilted) vertically relative to the production pallet 2 in the use state of the cleaning device 1, a contact pressure can be adjusted or contact can be established with the production pallet 2 by the brush 3. In general, the portal 8 itself can be designed to be height-adjustable.

[0070] The brush 3 is arranged on a profile rail 9 that is movably guided on the portal 8. Generally, the height of the brush 3 relative to the portal 8 or the production pallet 2 can be adjusted by moving the profile rail 9—for example, relative to the height-adjustable frame 29—although this is not absolutely necessary and the height adjustment is preferably achieved via the height-adjustable frame 29.

[0071] For height adjustment, a lifting motor (not shown for reasons of clarity) can generally be provided, with which the brush 3 can be moved in the use position of the cleaning device 1 in the vertical direction relative to the production pallet 2.

[0072] Fig. 3 differs from Fig. 2 only in the sense that the arrangement is shown from a viewing direction that differs by 90 degrees.

[0073] The longitudinal extension 4 of the brush 3 extends essentially over an entire longitudinal extension 10 of the profile rail 9. In general, the profile rail 9 can only be equipped with brushes 3 in certain areas, for example to clean a production pallet 2 with a smaller width 24 or to enable an adaptation of the cleaning device 1 for production pallets 2 with a greater width 24.

[0074] In general, it is possible to cover wider production pallets 2 by increasing the stroke or oscillating at a larger amplitude. Similarly, a narrower production pallet 2 (e.g., due to a thicker edge formwork 13) can be cleaned with a smaller oscillation amplitude without having to change the number of brush segments or brush sections.

[0075] In this embodiment, the brush 3 is mounted to the cleaning device 1 by means of screws. In general, clip connections, tool-free holding devices, or positive connection mechanisms (such as dovetail joints) can be used alternatively or additionally.

[0076] In this embodiment, the longitudinal extension 4 of the brush 3 amounts to at least 85% of the width 24 of the production pallet 2 orthogonal to the transport direction 25 of the production pallet 2.

[0077] The motor of the drive device 5 is coupled to the brush 3 via a transmission device such that a rotational movement of the drive device 5 is converted into a translational movement of the brush 3 along the longitudinal extension 4.

[0078] The drive device 5 has an eccentric unit 16 for moving the brush 3 along the longitudinal extension 4 of the brush 3.

[0079] A drive shaft 27 is connected to a connecting rod 28 via the eccentric unit 16, which moves the profile rail 9 on which the brush 3 is arranged. Alternative transmission mechanisms for the oscillatory movement of the brush 3 are possible.

[0080] In the illustrated embodiment, the cleaning device 1 comprises a row 20 of brushes 3 (as a unit in the form of a single brush 3). Generally, it is conceivable that at least two rows 20 of brushes 3 are arranged along the longitudinal extension 4, which may oscillate in opposite directions or alternately.

[0081] Preferably, at least two parallel rows 20 of brushes 3 are provided, which are arranged orthogonally to the longitudinal extension 4 one behind the other with spatial spacing between the rows 20. The at least two rows 20 are preferably driven by the same drive device 5 and, if appropriate, via the same eccentric unit 16. Advantageously, the oscillation movements of the at least two rows 20 are coupled such that the rows 20 oscillate in opposite directions or alternately.

[0082] Exactly one drive device 5 is provided for oscillating the brush 3. In the case of multiple rows 20, the one drive device 5 can be used to move the plurality of rows 20 in an oscillating manner.

[0083] Additional brushes 18 can be connected to the brush 3 in a modular manner to increase the longitudinal extension 4. A brush 3 as a brush segment (or brush section) of the brush 3 can be removed to reduce the longitudinal extension 4. The brush 3 or brush segments are arranged on the profile rail 9 of the cleaning device 1 so that they can be replaced for maintenance or cleaning.

[0084] With regard to the connection of the brush 3 to the cleaning device 1, a spring-loaded mounting is provided, wherein the brush 3 is mounted on the cleaning device 1 in a floating manner on plastic or rubber, whereby in the state of use of the cleaning device in the vertical direction (and / or in the transport direction) a flexibility of the brush and / or a kinematic compensation can be achieved in the event of particularly high force being applied to the brush 3.

[0085] The elastic mounting of the brush 3 is provided between the brush 3 and the profile rail 9, but can generally be arranged alternatively or additionally, for example, between the profile rail 9 and the drive device 5.

[0086] Fig. 4 shows an enlarged detail in the area of ​​the transmission of the oscillation movement from the drive device 5 to the brush 3.

[0087] Brush 3 is made of metal and is in the form of a steel brush. Generally, plastic bristles, for example, can be used as an alternative or in addition.

[0088] The width 6 of the brush 3 is approximately 10 cm.

[0089] The extension of the brush 3 along the longitudinal extension 4 is greater than a width 6 and height 7 of the brush 3, wherein the extension of the longitudinal extension 4 is at least 2 m.

[0090] Fig. 5 illustrates that the eccentric unit 16 in connection with the drive shaft 27 of the drive device 5 has bores which can be used individually for the connection or conversion of the rotational movement of the motor into the oscillation movement of the brush 3.

[0091] However, the oscillation movement is generally not limited to transmission by an eccentric unit 16.

[0092] Fig. 6a bis Fig. 6d The drilling pattern shown here illustrates different variants of connecting the eccentric in order to achieve varying strokes or oscillation amplitudes.

[0093] In Fig. 6a There is a deviation of the movement mediated by the eccentric unit 16 - via the connecting rod 28 - from the axis of symmetry in the form of the rotational axis of the drive shaft of the drive device 5 of approximately 3 mm. Fig. 6b This spatial distance of the rotational movement of the eccentric unit 16 from the rotational axis of the drive device 5 is approximately 6 mm. Fig. 6c the distance is approximately 9 mm and in Fig. 6c The distance is approximately 12 mm. Accordingly, the oscillation amplitude when using the drilling pattern according to Fig. 6d higher than when using the drilling pattern according to Fig. 6a .

[0094] The oscillation frequency can be controlled or regulated via the drive device 5, whereby oscillation frequencies are transmitted to the brush 3 in the range between 5 Hz and 0.1 Hz.

[0095] Fig. 7a shows a mounting of the brush 3 on the cleaning device 1, wherein the brush 3 is mounted via an air cushion 31 arranged within a hose 30—for example, a flexible plastic hose. The air cushion 31 is arranged between the brush 3 and the beam in the form of the profile rail 9.

[0096] In Fig. 7b It is shown that energy accumulators 32 in the form of springs are present in order to generate a restoring force depending on the air pressure in the hose 30.

[0097] Depending on the air pressure in the hose 30, the air cushion 31 can lead to an inflation of the hose 30 and thus to a vertical displacement of the brush 3.

[0098] The air cushion 31 can be used for elastic compensation of unevenness, for adjusting a contact pressure and / or for a vertical stroke of the brush 3 (for example for contacting the production pallet 2 or for overcoming a formwork element).

[0099] For example, the U-beam profile (on which the energy accumulators 32 act) and the profile rail 9 can remain stationary in the vertical direction and the brush 3 (with the guide frame arranged thereon for the lifting movement) can be pressed upwards or downwards depending on the air pressure in the hose 30 and / or the force applied by the energy accumulator(s) 32.
