Description

[0001] The invention relates to an arrangement for removing an application, such as a road marking, from a traffic area.

[0002] The invention also relates to a cleaning vehicle on which an arrangement for removing an application, such as a road marking, from a traffic area is arranged.

[0003] The device is used to remove deposits, such as road markings, that have been intentionally or inadvertently applied to a paved road surface. Such deposits include, for example, road markings deliberately applied to the paved road surface. Such deposits also include cargo that has inadvertently landed on the paved road surface during an accident, such as paint released during the accident, which constitutes the deposit.

[0004] Generally, such a coating, such as pavement markings, has a thickness ranging from 1 mm to 10 mm. In the case of a coating such as pavement markings or road markings, the coating typically consists of materials such as paint, spray plastic, cold-applied plastic, or thermoplastic. Epoxy resin materials or adhesive strips are also used for pavement markings or road markings.

[0005] The system for removing a coating, such as a road marking, from a traffic surface removes the coating from the paved traffic surface, a process also referred to as demarcation. In the following, the term "coat" will generally be used in this description without limiting the present invention in this way.

[0006] Pavement markings, or road markings, are required to ensure safe and orderly traffic flow on a paved surface, such as a road. However, at some point, it may be necessary to remove these pavement markings. This may be necessary to facilitate changes in traffic flow or to use the surface, such as a road, for another purpose. The removal of pavement markings may also be necessary for necessary construction work.

[0007] When removing the coating from the traffic area, high quality is required, as improper removal can compromise safety on the traffic area, such as a road, due to residues of the coating. Furthermore, wear and tear on the traffic area must be kept to a minimum to avoid damage and unnecessarily shorten the downtime of the traffic area.

[0008] It is known from the prior art to use a milling process for removing deposits such as road markings, whereby the deposit is removed mechanically by means of a rotating tool.

[0009] Alternatively, it is known to use surface treatment processes such as shot blasting, in which blasting media grains act on the deposit at high speed and remove it mechanically.

[0010] It is also known to use flame removal to remove the coating on suitable materials.

[0011] For example, removing a plastic coating (cold plastic or thermoplastic) is very complex according to the state of the art, as it requires various means, which are usually arranged on different vehicles.

[0012] It is known from the state of the art that in the case of particularly robust applications, such as markings made of cold plastic or thermoplastic, the removal of the application must be carried out in several steps, whereby in a first step a vehicle with a milling agent must be used, followed in a second step by a vehicle with a mechanical cleaning agent such as a sweeper and in a final third step by a vehicle with a high-pressure cleaning agent in order to achieve a sufficient demarcation result.

[0013] Such a large effort causes high fuel and water consumption and is therefore not sustainable.

[0014] From DE 26 50 487 a method and a device for removing road markings, in particular lane dividing lines, direction arrows, speed warnings and the like are known.

[0015] The task at hand is to develop a method that allows for the rapid removal of road markings with the least possible effort. Furthermore, the method should be feasible without significant technical complexity.

[0016] The solution is to subject the marking material to intense heating, which causes blistering, and then remove it with a rotating steel brush. This intense heating of the marking material, possibly to the point of blistering, tears the marking line and also makes the material so brittle that it easily breaks when it comes into contact with the steel brush.

[0017] A known disadvantage of the state of the art in removing deposits from a traffic area is that the removal requires a high level of technical effort and extensive resources, such as fuel, combustible material and water.

[0018] In addition, the removal result, also known as demarcation, is often inadequate. Furthermore, the traffic areas are subjected to considerable stress during the removal of the applied coating. Such stress can impair the service life of the traffic area or its robustness.

[0019] There is therefore a need for an improved arrangement for removing build-up from traffic areas.

[0020] The object of the invention is to provide an arrangement for removing a coating, such as a road marking, from a traffic area, which reliably removes a coating from a traffic area and avoids damage to the surface of the traffic area.

[0021] In addition, the arrangement for removing orders from a traffic area should be able to be coupled with existing vehicles or carrier vehicles and thus be used flexibly.

[0022] The arrangement should also be simple and inexpensive to manufacture and enable a reduction in the resources required, such as fuel and water, when removing the order.

[0023] The problem is solved by an object having the features according to claim 1. Further developments are specified in the dependent claims.

[0024] It is provided that an arrangement for removing an application, such as a road marking, from a traffic area has a support frame with wheels, wherein a milling means and a high-pressure cleaning means are arranged in the support frame and wherein the arrangement is arranged in a working position by means of the wheels so as to be substantially horizontally movable relative to the traffic area.

[0025] The assembly for removing debris from a traffic area comprises a rectangular support frame, for example, with several wheels mounted on this support frame. Thus, the support frame, i.e., the assembly for removing debris from a traffic area, can be moved or traversed across the traffic area in a so-called working position, in which the assembly removes the debris.

[0026] To remove the deposit from the traffic area, the assembly is moved parallel to a surface of the traffic area in the working position. The assembly is positioned at a short distance from the surface of the traffic area, allowing the assembly's working tools to effectively remove the deposit from the surface. In the working position, the assembly rolls across the traffic area using its multiple wheels.

[0027] For transport, before or after removing the work from the traffic area, the assembly is moved or traversed from the working position to a so-called transport position, whereby the distance of the assembly from the surface of the traffic area is increased. The distance of the assembly from the surface of the traffic area in the transport position is selected to enable quick and safe transport of the assembly. In particular, the transport position ensures that the assembly's working equipment is not damaged by unintentional contact with the traffic area or obstacles on the traffic area.

[0028] In one embodiment of the assembly, four wheels are arranged in the corner areas of the rectangular support frame. These wheels are pivotably mounted on the support frame. In an alternative embodiment, only some of the wheels, for example, two wheels, are pivotably mounted. In this embodiment, the other two wheels are fixed and are arranged on the support frame facing in one direction of movement of the assembly.

[0029] The assembly's support frame houses the equipment used to remove the debris from the traffic area. These equipment includes a milling tool and a high-pressure cleaning tool, which are arranged separately and spaced apart from each other within the support frame.

[0030] To remove the deposit from the traffic area, the milling tool and the high-pressure cleaning device are moved with the assembly essentially horizontally or parallel to the surface of the traffic area. The milling tool first mechanically removes a significant portion of the deposit, and the high-pressure cleaning device subsequently removes the portion of the deposit not completely removed during milling. Thus, with respect to the direction of movement of the assembly over the traffic area in the working position, the milling tool is positioned in front of the high-pressure cleaning device in the assembly.

[0031] It is further provided that first coupling means are arranged on the carrier frame, by means of which the arrangement can be attached to a carrier vehicle.

[0032] The arrangement for removing deposits from a traffic area is attached to a carrier vehicle, such as an existing cleaning vehicle, and moved with this carrier vehicle both in the transport position and in the working position. For this purpose, first coupling means are arranged on the carrier frame, which mechanically couple or connect the arrangement to corresponding means of the carrier vehicle. Generally, these first coupling means provide at least part of a detachable connection so that the arrangement can be fastened to the carrier vehicle. These first coupling means also enable the arrangement to be removed from the carrier vehicle, for example to carry out maintenance and / or repair work on the arrangement or in the event that the carrier vehicle is to be coupled to other means for a use other than removing deposits from the traffic area.

[0033] In particular, it is provided that the milling means is arranged in a first housing in the arrangement and that the high-pressure cleaning means is arranged in a second housing in the arrangement, wherein both housings are open towards the traffic area.

[0034] The working tools of the assembly are arranged in the support frame, spaced apart from each other and arranged side by side. To ensure the proper functioning of the milling tool and the high-pressure cleaning tool, the working tools or their working areas must not interfere with each other. For this purpose, the working areas in which a milling process takes place on the one hand and a high-pressure cleaning process on the other, and thus the working tools, are each arranged within a housing within the assembly.

[0035] In this arrangement, the milling tool is housed in a first housing, and the high-pressure cleaning tool is housed in a second housing. To ensure the proper functioning of the tools, both housings are open to the traffic area.

[0036] To further define the working areas of the milling tool and the high-pressure cleaning agent, circumferential brush strips are arranged in the lower sections of the housing. These brush strips prevent the escape of removed material and the escape of cleaning agent from the high-pressure cleaning agent from the working areas. Furthermore, these brush strips improve the suction process from the working areas, in which, in particular, removed material is removed from the working areas of the working agents and fed into a collection container.

[0037] It has proven particularly advantageous that the milling means is arranged to be rotatable about a first axis and that the high-pressure cleaning means is arranged to be rotatable about a second axis, wherein both axes are aligned perpendicular to a surface of the traffic area and are arranged at a distance from one another in the arrangement.

[0038] The milling means is rotatably mounted in the arrangement and rotates around a first axis in its working area within the first housing. The high-pressure cleaning means is also rotatably mounted in the arrangement and rotates around a second axis in its working area within the second housing.

[0039] Both axes are aligned vertically or perpendicularly, in particular perpendicular to the surface of the traffic area. In other words, the axes are arranged at a substantially right angle to the surface of the traffic area. The axes are thus arranged parallel to each other and spaced apart from each other in the arrangement, with the spacing corresponding to the distance between an imaginary center of the milling means and an imaginary center of the high-pressure cleaning means.

[0040] In one embodiment, the milling means is designed as a rotatably mounted, circular milling head rotating horizontally around the first axis. This milling head of the waterless milling means rotates in a plane, for example, parallel to the surface of the traffic area, and has a number of milling plates mounted in a circular outer region of the circular milling head. Materials such as polycrystalline diamonds (PCD) are used for the milling plates, in particular the milling zone. In one embodiment of a circular milling head, between ten and twenty milling plates, in particular sixteen milling plates, are arranged in the outer region of the circular milling head. Each of these milling plates is further equipped with two to six milling teeth, in particular four milling teeth.In an alternative design, the circular milling head rotates in a plane that is inclined at an angle of between 3 degrees and 10 degrees to the surface of the traffic area.

[0041] In one embodiment, the high-pressure cleaning device is designed as a rotatably mounted nozzle bar rotating about the second axis. This nozzle bar, which rotates in a plane parallel to the surface of the traffic area, has several nozzles on its underside. These nozzles are arranged, for example, in one or two rows, whereby the nozzles can be oriented in slightly different directions from one another. Essentially, the nozzles are directed toward the surface of the traffic area.

[0042] A cleaning medium, such as water, is supplied to the rotating nozzle bar, for example via a high-pressure line from the carrier vehicle.

[0043] The cleaning agent, pressurized at high pressure (e.g., 3000 bar), emerges from the nozzles of the rotating nozzle bar, impinging on the firmly adhered coating, thereby mechanically detaching it from the surface. To achieve this, the nozzle bar of the high-pressure cleaning agent rotates in a plane parallel to the surface of the surface.

[0044] It is further provided that a first suction connection is arranged on the first housing of the milling means and a second suction connection is arranged on the second housing of the high-pressure cleaning means.

[0045] In order to remove debris loosened from the traffic area by the work equipment from the working areas of the work equipment of the arrangement for removing debris from a traffic area, suction connections are arranged on the housings of the work equipment.

[0046] In this case, a first suction connection is arranged on the first housing of the milling device and a second suction connection, independent of the first suction connection, is arranged on the second housing of the high-pressure cleaning device.

[0047] This makes it possible to separate the debris removed from the traffic area from the working areas of the equipment. This design allows, for example, different suction pressures and thus different suction power levels to be set in the different working areas.

[0048] It has also proven advantageous that the first suction connection and the second suction connection are each connected to a suction device of the carrier vehicle via a flexible hose.

[0049] The carrier vehicle, such as a cleaning vehicle (sweeper), has a means for collecting dirt. This means comprises a suction device that creates a vacuum and a collection container in which, for example, dirt or debris removed from the surface of the traffic area is collected.

[0050] The dirt collection device mounted on the carrier vehicle is connected to the first suction port of the first housing of the milling device via a first flexible hose. Thus, debris removed from the milling device can be removed from the working area of ​​the milling device and transported into the collection container using negative pressure.

[0051] The dirt collection device mounted on the carrier vehicle is further connected to the second suction port of the second housing of the high-pressure cleaner via a second flexible hose. Thus, debris removed by the high-pressure cleaner can be removed from the working area of ​​the high-pressure cleaner and transported into the collection container using negative pressure.

[0052] One version of the dirt collection device features two suction devices, each independently generating a vacuum. This allows the vacuum for removing the loosened debris to be adjusted differently for the different work areas of the system.

[0053] It is also provided that further electrical and / or hydraulic coupling means are arranged on the arrangement, by means of which the arrangement and / or the milling means and / or the high-pressure cleaning means are connected to the carrier vehicle for control and / or drive.

[0054] Detachable electrical connections are established between the carrier vehicle and the assembly by means of additional electrical coupling means. Such connections are required, for example, for electrically controlling the assembly or the assembly's working equipment. Such connections are also required for transmitting measured values ​​from sensors to the carrier vehicle, with these sensors being arranged in the assembly or the assembly's working equipment.

[0055] Detachable hydraulic connections are established between the carrier vehicle and the assembly by means of additional hydraulic coupling means. Such connections are used, for example, to supply pressurized hydraulic fluid to drive means in the assembly.

[0056] Such drive means can be used to generate linear movements within the arrangement. For example, using appropriate hydraulic cylinders, flaps within the arrangement can be moved or the height of the arrangement above the traffic area can be changed. Such drive means can also be used to generate rotary movements or rotation of the working equipment within the arrangement.

[0057] It is particularly advantageous that a first hydraulic drive is arranged on the milling device and a second hydraulic drive is arranged on the high-pressure cleaning device.

[0058] The milling tool is set into a rotary movement or rotation by means of a first hydraulic drive.

[0059] The high-pressure cleaning agent is set into a rotary motion or rotation by means of a second hydraulic drive.

[0060] This ensures that the working elements of the assembly can be controlled independently of one another. Generally, the assembly and its working elements are controlled by a central control system, located, for example, in the carrier vehicle. For this purpose, the central control system is connected to the assembly and its working elements via the additional electrical coupling devices.

[0061] Thus, the invention makes it possible to switch the working devices on and off independently of one another and to operate the working devices at different speeds. This also makes it possible to change the operation of the arrangement during operation, in which the arrangement is in the working position, for example, to adapt to different thicknesses of the coating or to adapt to a changing surface of the traffic area.

[0062] The invention also relates to a cleaning vehicle comprising an arrangement for removing an application, such as a road marking, from a traffic area according to claims 1 to 10.

[0063] It is particularly advantageous if the assembly for removing debris from a traffic area is mounted on a cleaning vehicle and moved with it. In this way, the assembly can be connected to means or components of the cleaning vehicle, such as a central control system, a hydraulic system, a suction device, or a collection container.

[0064] The arrangement is moved with the cleaning vehicle, which is the carrier vehicle of the arrangement, and is also operated during ongoing operation, i.e. when the order is removed from the traffic area in the working position.

[0065] According to the invention, it is also provided that the arrangement on the cleaning vehicle is arranged on a front crane of the cleaning vehicle or in an area between the vehicle axles of the cleaning vehicle.

[0066] The assembly allows for use with various carrier vehicles (sweepers) available on the market or already in a fleet, as the assembly can be coupled to these carrier vehicles and operated with a carrier vehicle in the working position. The assembly is already prepared accordingly and can be attached to a carrier vehicle with minimal effort. The coupling elements of the assembly are designed accordingly. The assembly is implemented with various coupling elements, allowing for easy coupling with different carrier vehicle series.

[0067] In a first variant, the assembly is mounted on a front crane of the cleaning vehicle and operated by it. For this purpose, appropriate means for electrical and / or hydraulic coupling to the assembly are arranged on the front crane. The assembly is moved into the working and transport positions by the front crane or by means of a hydraulic system on the front crane.

[0068] In a second variant, the arrangement is located in an area between the axles of the cleaning vehicle. In vehicles such as sweepers, a cleaning or sweeping agent is typically located in this area.

[0069] Advantages of the arrangement according to the invention include the combination of a milling device with a high-pressure cleaning device in a single mobile arrangement. Furthermore, the arrangement can be retrofitted to vehicles with hydrostatic drives, allowing the use of existing attachment systems between the vehicle axles or on a front-mounted crane. The coupling elements of the arrangement are compatible with these attachment systems. Thus, an existing fleet of carrier vehicles can be used with the arrangement.

[0070] The inventive combination of several working media in the arrangement leads to lower consumption of fuel and / or a cleaning medium such as water. This reduces operating costs and makes the removal of the deposit more sustainable.

[0071] The modular design of the assembly's work equipment allows for interchangeability of the milling and water cleaning components, for example to adapt to different jobs, as well as easy maintenance and repair of the work equipment. The arrangement can advantageously be connected and operated with suction devices and collection tanks already present or installed on carrier vehicles.

[0072] Further details, features, and advantages of embodiments of the invention will become apparent from the following description of exemplary embodiments with reference to the accompanying drawings. They show: Fig. 1: a first embodiment of the arrangement according to the invention for removing deposits from a traffic area in a view obliquely from below, Fig. 2: the arrangement according to the invention in a view obliquely from above, Fig. 3: the arrangement according to the invention in a sectional view, Fig. 4: a cleaning vehicle according to the invention with the arrangement in a first embodiment and Fig. 5: a cleaning vehicle according to the invention with the arrangement in a second embodiment.

[0073] The Fig. 1 shows a first embodiment of the arrangement 1 according to the invention for removing deposits from a traffic area in a view obliquely from below. The assembly 1 comprises a support frame 2 with four wheels 3. In the illustrated embodiment, the wheels 3 are pivotably arranged.

[0074] A milling device 4 and a high-pressure cleaning device 5 are arranged in the support frame 2 as the working devices of the assembly 1. The working devices 4 and 5 are moved essentially horizontally with the assembly 1 in a so-called working position by means of the wheels 3 relative to a traffic area (not shown) in order to remove deposits from a traffic area.

[0075] In the illustrated embodiment of the arrangement 1, four wheels 3 are arranged in the corner areas of the rectangular support frame 2. These wheels 3 are pivotally mounted on the support frame 2.

[0076] It is provided that at least one first coupling means 6 is arranged on the support frame 2, by means of which the arrangement 1 can be attached to a carrier vehicle (not shown). By means of the first coupling means 6, the arrangement 1 is attached to a carrier vehicle, such as a road sweeper, and is moved with this carrier vehicle both in the transport position and in the working position of the arrangement 1. For this purpose, at least the first coupling means 6 is arranged on the support frame 2, via which the arrangement 1 is mechanically coupled or connected to corresponding means of the carrier vehicle. The first coupling means 6 forms at least part of a detachable connection to the transport vehicle.This first coupling means 6 also enables the arrangement 1 to be removed from the carrier vehicle, for example to carry out maintenance and / or repair work on the arrangement 1 or in the event that the carrier vehicle is to be coupled to other means for a use other than removing the order from the traffic area.

[0077] The working tools 4 and 5 of the assembly 1 are arranged spaced apart from each other and adjacent to each other in the support frame 2 of the assembly 1. To ensure the proper functioning of the milling tool 4 and the high-pressure cleaning tool 5, the working tools 4, 5 or their working areas must not interfere with each other. For this purpose, the working areas are each arranged within a housing 7, 8.

[0078] In arrangement 1, the milling means 4 is arranged in the first housing 7 and the high-pressure cleaning means 5 in the second housing 8. To ensure the functionality of the working means 4, 5, both housings 7, 8 are open towards the traffic area (not shown), i.e., at the bottom.

[0079] To further define the working areas of the milling tool 4 and the high-pressure cleaning agent 5, circumferential brush strips 9 are arranged in the lower areas of the housings 7, 8. These brush strips 9 prevent the escape of removed material and the escape of cleaning medium from the high-pressure cleaning agent 5 from the working areas. Furthermore, these brush strips 9 improve the suction, in particular of the removed material, from the working areas of the working tools 4 and 5.

[0080] The milling means 4 is arranged in its working area in the first housing 7 so as to be rotatable about a first axis 10. The high-pressure cleaning means 5 is arranged in its working area in the second housing 8 so as to be rotatable about a second axis 11. The two axes 10 and 11 are aligned perpendicular to a surface of the traffic area and arranged at a distance from one another in the arrangement 1. The axes 10 and 11 are thus arranged essentially at a right angle to the surface of the traffic area. The axes 10 and 11 are also arranged parallel to one another and at a distance from one another in the arrangement 1. The distance between the axes 10 and 11 corresponds to the distance between an imaginary center point of the milling means 4 and an imaginary center point of the high-pressure cleaning means 5.

[0081] The milling means 4 is in the embodiment of the Fig. 1 as a rotatably mounted circular milling head 12 rotating substantially horizontally about the first axis 10. This milling head 12 rotates in a plane, for example parallel to the surface of the traffic area, and has a number of, for example, ten milling plates 13. The milling plates 13 are mounted in a circular outer region of the circular milling head 12 and consist, for example, of polycrystalline diamonds. Each of these milling plates 13 is further equipped with, for example, four milling teeth, which in the Fig. 1 is not shown.

[0082] In one embodiment, the high-pressure cleaning device 5 is designed as a rotatably mounted nozzle bar 14 rotating about the second axis 11. This nozzle bar 14, which rotates in a plane parallel to the surface of the traffic area, has a plurality of nozzles 15 on its underside. These nozzles 15 are arranged, for example, in one or two rows, wherein the nozzles 15 can be oriented in slightly different directions from one another. Essentially, the nozzles 15 are oriented toward the surface of the traffic area (not shown).

[0083] A cleaning medium, such as water, is supplied to the rotating nozzle bar 14, for example, via a high-pressure line from the carrier vehicle. The cleaning medium, at high pressure of, for example, 3000 bar, emerges from the nozzles 15 of the rotating nozzle bar 14, impacts the deposit firmly adhering to the traffic surface, and thus mechanically detaches it from the traffic surface. For this purpose, the nozzle bar 14 of the high-pressure cleaning agent 5 rotates in a plane parallel to the surface of the traffic surface.

[0084] Furthermore, in the Fig. 1 a first suction connection 16 arranged on the first housing 7 can be seen. It is somewhat worse in the Fig. 1 the second suction connection 17 arranged on the second housing 8 can be seen.

[0085] The Fig. 2 shows the arrangement according to the invention in a view obliquely from above.

[0086] In the Fig. 2, the rectangular support frame 2, the four wheels 3, the first coupling means 6, the first and second housings 7 and 8, each with a brush strip 9, can be seen in the view obliquely from above.

[0087] Furthermore, the first axis 10 and the second axis 11 as well as the first suction connection 16 and the second suction connection 17 are shown.

[0088] In the presentation of the Fig. 2 also shows a first drive 18 and a second drive 19. The first drive 18 is a hydraulic drive that drives the milling plate 13 of the milling device 4, while the second drive 19, which is also a hydraulic drive, causes the nozzle bar 14 of the high-pressure cleaning device 5 to rotate.

[0089] In the Fig. 3 shows the arrangement according to the invention in a sectional view along a central longitudinal axis of the arrangement 1.

[0090] In the sectional view of the Fig. 3 shows the rectangular support frame 2, two of the four wheels 3, the first coupling means 6, the first and second housings 7 and 8 each with a brush strip 9.

[0091] Also shown are the first axis 10 and the second axis 11, the first suction port 16 and the second suction port 17, as well as the first drive 18 and the second drive 19. The milling plate 13 can be seen in the first housing 7, and the nozzle bar 14 can be seen in the second housing 8.

[0092] In the presentation of the Fig. 3, the first drive 18 and a second drive 19 are shown next to the corresponding axes 10 and 11 of the milling means 4 and the high-pressure cleaning means 5, respectively. For transmitting the rotary motion generated by the drive 18 and 19 to the axes 10 and 11, appropriate means such as belts, toothed belts or gears are provided, which are shown in the Fig. 3 are not shown.

[0093] The Fig. Figure 4 shows a cleaning vehicle 20 according to the invention with the assembly 1 in a first embodiment. The illustration only shows the principle of positioning the assembly 1 on a carrier vehicle, which is necessary for explanation. A detailed representation of the individual components has been omitted.

[0094] In this first embodiment, the assembly 1 is arranged on the cleaning vehicle 20 in an area between the vehicle axles 21 of the cleaning vehicle 20. In carrier vehicles known from the prior art, such as a sweeper, an assembly with a rotary broom and a suction device is typically arranged in this area between the vehicle axles 21.

[0095] In the Fig. Figure 5 shows a cleaning vehicle 20 according to the invention with the assembly 1 in a second embodiment. This illustration shows only the principle of positioning the assembly 1 on a carrier vehicle, which is necessary for explanation. A detailed representation of the individual components has been omitted.

[0096] In this second embodiment, the arrangement 1 is arranged on the cleaning vehicle 20 on a front crane 22 of the cleaning vehicle 20. The schematic diagram also shows the first suction connection 16 and the second suction connection 17, which are each connected via flexible hoses 23 to a suction means (not shown) of the cleaning vehicle 20. This connection enables the suction of the removed application from the working areas of the arrangement and the feeding of the removed application to a collecting container in the cleaning vehicle 20, which is in the Fig. 5 is not shown.
