Description

Technical field

[0001] The present invention relates to a self-propelled cleaning system for cleaning the surfaces of an interior space, in particular of a vehicle and / or container, wherein the cleaning system comprises the following assemblies: A first assembly I, consisting of a frame as a support for receiving the individual assemblies II - V, a second assembly II, consisting of a traversing unit for realizing the feed movement for forward and reverse travel, a third assembly III, consisting of a guide unit for guiding the cleaning system to the interior walls during the cleaning process, a fourth assembly IV consisting of a cleaning unit and a fifth assembly V consisting of a drying unit, according to claim 1.

[0002] Furthermore, the present invention relates to a method for cleaning the surfaces of an interior space, in particular of a vehicle and / or container, with the features of claim 12. State of the art

[0003] Self-propelled cleaning systems for cleaning interior surfaces, particularly those of vehicles and / or containers, especially refrigerated trailers, are known from the prior art. The surfaces are cleaned by applying liquids or other flowable substances. These liquids may contain cleaning and disinfecting agents and are applied to the surfaces using jet nozzles or spray jets.

[0004] For example, US Patent 4,309,788 A discloses a self-propelled cleaning device with a frame to which cleaning attachments are mounted. The frame consists of a drive carriage equipped with thick, rubber-tired drive and guide wheels. Cleaning the ceiling and end walls of a container is not possible with this mobile cleaning device. A drying system is also lacking. Furthermore, the cleaning device cannot be positioned centrally in the cargo area of ​​a truck. The same applies to the self-propelled cleaning device described in US Patent 4,784,166 A. This cleaning device does not have a modular design. US Patent 3,830,430 A also describes a self-propelled cleaning cart. However, this cart lacks a modular design and a cleaning method that complies with the new regulations of DIN 10516 "Food Hygiene - Cleaning and Disinfection".

[0005] US Patent 4,141,374 A describes a self-propelled cleaning device capable of spraying water or a cleaning fluid supplied from an external source via a hose reel. However, it lacks a drying system and the ability to precisely center the cleaning device within the cargo space being cleaned.

[0006] WO 2007 / 000 538 A2 also discloses a device for cleaning the interior of a container. However, a defined high-pressure cleaning of the five interior surfaces and mechanical drying of these surfaces are not possible. Furthermore, centering the mobile cleaning device and precisely maintaining its path along the walls are not feasible.

[0007] Another type of drive for a cleaning device for washing the interiors of containers can be found in EP 0 940 192 A2. The cleaning devices are arranged on a frame connected to an accordion-like drive. However, centering the mobile cleaning device and precisely maintaining a path along the walls is not possible.

[0008] Another self-propelled cleaning vehicle with lateral guide wheels is disclosed in FR 2 925 372 A1. Centering and precise adherence to the driving path, and thus maintaining the exact distance between the cleaning nozzles and the loading areas of a truck interior, is not possible with this drive and lateral guidance system. While the front wall can be cleaned across a surface, it cannot be cleaned in a rectangular shape due to the rotating design of the cleaning lances. Mechanical drying of the cleaned surfaces also does not occur.

[0009] Also worth mentioning is the cleaning trolley for washing internal surfaces, such as those of a truck trailer or container, from EP 2 618 949 B1. This cleaning trolley has a mobile frame on which pipes with cleaning nozzles are mounted. Lateral guidance of the trolley, consisting of simple wheels, is provided, but cleaning of the front wall and mechanical drying of the cleaned surfaces are not possible. Furthermore, with this drive and lateral guidance system, centering and precise adherence to the travel path, and thus maintaining the exact distance between the cleaning nozzles and the surfaces to be cleaned in a truck interior, are not possible.

[0010] The closest prior art is considered to be the device for cleaning the interior of compartments, particularly refrigerated containers, especially those mounted on trucks, as disclosed in WO 2010 / 052318 A1. WO 2010 / 052318 A1 discloses a self-propelled cleaning system equipped with rotating cleaning heads, each fitted with at least three nozzles for spraying pressurized cleaning fluid, and a static washing nozzle that generates a mist from the cleaning fluid throughout the compartment. Lances, each rotatable about an axis, are arranged laterally on the cleaning block for cleaning the side walls. Two vertical, statically arranged lances for cleaning the side walls and one horizontal lance for cleaning the bottom wall are provided on the front cleaning block. The numerous geared motors are also a cost disadvantage. Four geared motors are required for the cleaning heads and lances alone.Additional geared motors are provided to drive the drive wheels. Guide elements consisting of freewheel wheels are arranged laterally on the cleaning block to guide the self-propelled cleaning system; these are not suitable for centering the cleaning system. A centering unit for automatically centering the cleaning system relative to the cargo space and a drying system are not included.

[0011] Furthermore, a cleaning system in the form of a cleaning robot is known from document US 2019 / 0023234 A1.

[0012] All of the aforementioned prior art designs share the common flaw that they do not allow for precise, centered guidance of the cleaning equipment before the start of the cleaning process and during its movement through the interior. Furthermore, all cleaning systems lack a drying unit. Object of the invention

[0013] Based on this prior art, the object of the invention is to avoid the aforementioned disadvantages of the prior art. It aims to develop a method for cleaning interiors and to provide a drive and lateral guide that enable smooth and precise traversing of uneven or structured surfaces, such as those found on shipping containers. Furthermore, it aims to provide a self-centering mechanism for a self-propelled cleaning system so that the cleaning system's path can be aligned with the floor, side walls, and ceiling to within a few millimeters. Therefore, design measures are necessary to prevent collisions between the cleaning system and the interior walls of a container. A reduction in water consumption during the cleaning process is also to be achieved. Finally, a drying system and an extraction system are to be provided.The required cleaning quality must at least meet the standards of DIN 10516 "Food hygiene - Cleaning and disinfection". The cleaning system and the cleaning process must therefore fulfill these requirements. Description of the invention

[0014] At the start of the cleaning process, the cleaning unit is mounted on a lifting device, preferably a forklift. In the first step of the process, the cleaning unit is positioned at the height of the loading area edge, depending on the cleaning process being carried out. Once the positioning is complete, the cleaning unit moves into the container.

[0015] The primary function of the cleaning system is the cleaning and disinfection of a truck cargo area and / or a container, particularly a refrigerated trailer. A force must be generated to detach contaminants from a surface. This force must be greater than the adhesive force of the dirt to the surface. The force required to detach the dirt can be generated chemically, mechanically, or as a combination of both mechanisms. To clean the entire surface of a truck cargo area or container, especially a refrigerated trailer, relative movement between the cleaning system and the refrigerated trailer is necessary. In the following text, the term "container" will be used interchangeably with the various terms "truck cargo area," "container," "refrigerated trailer," "semi-trailer," etc.To ensure that the cleaning process runs smoothly, constructive measures must be taken to avoid collisions between the container and the cleaning system.

[0016] To achieve this, it is proposed that, in a self-propelled cleaning system for cleaning interior surfaces, particularly those of a vehicle and / or container, the standard drive unit from the prior art be replaced by an inventive traversing unit. The traversing unit, which implements the forward and reverse movement for travel in the longitudinal plane of a truck or container, must be designed to meet higher demands on the guidance of the cleaning system. The traversing unit should be able to compensate for uneven surfaces without deflecting the cleaning system from its precise path. Precise guidance of the cleaning system allows the horizontally arranged cleaning pipes and nozzles to maintain a smaller, constant distance from the floor and ceiling walls.Due to the small, constant distance between the nozzles, consistent cleaning results in lower water consumption. Furthermore, the close proximity of the nozzles to the surface being cleaned generates greater force from the high-pressure water jet on the dirt particles, thus shortening the cleaning time for a given area or the entire interior. The further a nozzle is from the surface being cleaned, the more the high-pressure water jet spreads out, and the water pressure per unit area decreases. The same applies if the cleaning system's design allows for excessive variation in the distance between the nozzles and the surface being cleaned. To comply with the hygienic cleanliness required by European food law, consistently high-quality cleaning must be guaranteed throughout the entire cleaning process.The cleaning effect is advantageously increased by the flat nozzles, which can be positioned at an angle and are placed close to the surface to be cleaned.

[0017] To ensure smooth operation and precise control of the cleaning system during the cleaning process, wheels or rollers are not used, as is known in the prior art. Advantageously, so-called tank tracks are employed, which can easily traverse uneven surfaces and textured surfaces such as profiled sheets, for example, trapezoidal sheets or similar.

[0018] According to the invention, the transport unit therefore consists of two drive units arranged parallel to each other and equipped with conveyor belts. These drive units are positioned below the frame of the cleaning system, extending in the direction of forward and reverse travel. The drive units are connected to each other via a common drive shaft. The drive shaft runs transversely to the drive units at the rear end of the frame and is driven by a geared motor.

[0019] Toothed belts are used as conveyor belts, which, with a suitable coating, achieve excellent traction, especially on wet, dirty surfaces. Slip-free operation is guaranteed, as is exceptionally smooth running. A further advantage is that the surface pressure of the cleaning system is significantly lower than with conventional tires. The transport speed ranges from 0.2 to 80 m / min, a speed that cannot be achieved with a cleaning system alone, thus ensuring a long service life for the toothed belts. This type of drive unit facilitates the relative movement between the cleaning system and a container.

[0020] The nozzles of the vertical cleaning pipes, used to clean the side surfaces of an interior space, are subject to the same conditions. These nozzles, too, must maintain a constant distance from the surface being cleaned to ensure consistently good cleaning throughout the process. This is especially important for containers that do not have flat surfaces but rather textured sides.

[0021] To meet, for example, the requirements for smooth operation of a cleaning system, a guide and centering unit according to the invention is used for the cleaning system. The guide and centering unit consists of two toothed belt drives, spaced parallel to each other and equipped with conveyor belts, which are arranged laterally on the left and right sides of the frame, running in the direction of forward and reverse travel. The toothed belt drives have a rear movable flange bearing pair and a front movable flange bearing pair. The flange bearing pairs connect the toothed belt drives to the frame. All flange bearing pairs point in the same direction. In the front flange bearing pair, the upper flange is designed as a longer lever to which a movable connecting rod is attached, and the other end of which is movably connected to a linear unit.The linear unit is driven by a drive cylinder, with the linear unit being arranged centrally on the horizontal plane of the frame, extending in the direction of forward and reverse travel.

[0022] Here too, toothed belts are used as conveyor belts, which, with an advantageous coating, achieve a smooth and backlash-free guidance, especially on wet, dirty side walls of the interiors of containers.

[0023] To prevent collisions between a cleaning system and the interior walls of a container, further design measures are required. These measures consist of technically implementing a movable guide and centering unit on the frame in such a way as to achieve a modular design. This is accomplished using connecting elements that allow for a movable connection between the guide and centering unit and the frame. Advantageously, these connecting elements consist of front and rear flange bearing pairs, each comprising two flanges spaced parallel and perpendicular to each other. The rear flanges and the two front flanges are of equal length, and the rear and front flanges are arranged on the side guides of the toothed belt drive housings, thus ensuring that the toothed belt drives maintain a constant distance from the linear unit along their entire length.

[0024] The previously described guide and centering unit corrects even minimal misalignment of the cleaning system relative to the container's side walls before the cleaning process begins. The guide and centering unit positions the cleaning system centrally within the container's cargo space. This positioning is achieved by flat belt drives located on both sides of the frame. Before the positioning process starts, the cleaning system is lifted using a lifting device. This device raises the entire cleaning system until the drive units of the traversing unit no longer touch the bottom wall of the container's cargo space.

[0025] Advantageously, the lifting device consists of at least one lifting plate, preferably two lifting plates. Each lifting plate supports lifting cylinders and ball rollers, and each lifting plate comprises an elongated flat steel bar with a central web. This web has at least two projecting, flat supports on each side, lying in the plane of the flat steel bar, and preferably four supports. The supports are spaced longitudinally apart and each support accommodates one lifting cylinder. Each lifting plate has at least three ball rollers, preferably fourteen ball rollers per lifting plate, on the left and right sides and along the central web. A larger number of ball rollers is also conceivable. The lifting cylinders consist, for example, of pneumatic, electric, or hydraulic cylinders, preferably electric cylinders.The electric cylinders are attached to the frame of the cleaning system on one side and to the lowering lifting device on the other. The eight electric cylinders, positioned between the frame and the lifting plates, are extended until the two lowered lifting plates of the lifting device, with their twenty-eight ball rollers, make contact with the floor wall of a cargo or container compartment, and the drive units of the traversing unit are free. With the drive units decoupled, the cleaning system can be rotated on the spot or positioned between the side walls of a container compartment, because the ball rollers of the cleaning system allow free movement in the plane, or parallel to the floor wall of a cargo or container compartment.

[0026] The centering process of the cleaning system therefore takes place in two steps. In the first step, the cleaning system is lifted by the electric cylinders until it rests solely on the ball rollers embedded in the lifting device. With the lifting of the cleaning system, the decoupling of the drive units is complete. The second step initiates the centering process. This is achieved by the parallel extension of the two flat belt drives, preferably toothed belt drives, which are arranged laterally on the frame. The toothed belt drives are connected via a four-bar linkage to a linear unit located centrally on the frame. A four-bar linkage is a combination of a toothed belt drive, a movable lever I connected to it, and a movable connecting rod connected to the movable lever, which in turn is connected to a linear unit.In the linear unit, the connecting rod, and thus all the levers of the four-bar linkage connected to it, are moved by a linear actuator. The linear actuator consists of a hydraulic, pneumatic, or electric drive cylinder, preferably an electric cylinder. The stroke of the electric cylinder's piston rod acts along the central axis of the cleaning system. When the electric cylinder's piston is extended, the connecting rod moves, and consequently, so do the other levers that act on the toothed belt drive. Extending the piston rod moves the extension mechanism, which is designed like a scale. The movement of the four-bar linkage extends the two toothed belt drives parallel to the width of the interior of a cargo or container space, i.e., until they contact the side walls. This contact with the side walls centers the cleaning system within the cargo space.Once the centering process is complete, the eight electric cylinders retract, and the connection between the drive unit's conveyor belts and the floor wall of a loading or container space is re-established. The cleaning system is now in its home position. From this home position, after lifting, centering, and lowering the cleaning system, the normal cleaning process typically begins.

[0027] To carry out a cleaning process, the cleaning system is advantageously equipped with a cleaning unit. The cleaning unit consists of two independent sub-units, I and II. A first sub-unit, I, comprises three cleaning tubes rotatable in bearing blocks, each with a drive cylinder. The drive cylinders preferably consist of an electric motor capable of rotating the cleaning tubes about their longitudinal axis. Precise rotation of the cleaning tubes through a predetermined angular range can be set using gears. The bearing blocks of the cleaning tubes are fixed to the frame. A second sub-unit, II, consists of a movable horizontal cleaning tube. The cleaning tube is mounted on two vertical conveyor belts. The conveyor belts have a common lower drive shaft, two upper deflection shafts, and a drive unit.The lower drive shaft and the two upper deflection shafts are firmly attached to the frame via bearing mounts.

[0028] Sub-unit I of the cleaning system comprises two vertical and one horizontal cleaning tube. One vertical cleaning tube is attached to the left vertical tube and the other to the right vertical tube of the frame's support structure. The horizontal cleaning tube is attached to the lower horizontal tube of the frame's base. All three cleaning tubes have fan nozzles at specific intervals on their front and connections for hoses on their rear. In the cleaning system's initial position, the fan nozzles of the two vertical tubes and the lower horizontal tube point perpendicular to the side and bottom walls. After the cleaning process is initiated, the two vertical tubes and the lower horizontal tube, along with their attached fan nozzles, are rotated 45 degrees in the forward direction by means of the electric cylinders connected to the cleaning tubes.For reverse travel, the fan nozzles are rotated 90 degrees backward. Now, the angle of inclination of the fan nozzles on the upper horizontal cleaning tube must be considered. The upper horizontal cleaning tube is responsible for cleaning the ceiling and end walls. When the cleaning system starts, the fan nozzles of the upper horizontal cleaning tube are also rotated 45 degrees in the forward direction. After reaching the end wall, the fan nozzles swivel another 90 degrees clockwise, and the horizontal cleaning tube then travels down the end wall. Upon reaching the floor wall, the fan nozzles swivel 90 degrees counterclockwise. After a certain contact time, the horizontal cleaning tube travels upward along the end wall to the ceiling wall. Upon reaching the ceiling wall, the fan nozzles swivel another 45 degrees counterclockwise.For the return journey, all fan nozzles of the other cleaning pipes also swivel back by 90 degrees, so that all fan nozzles point 45 degrees towards the exit during the return journey of the cleaning system.

[0029] In a first embodiment, the horizontal cleaning tube of component II, which is used to clean the ceiling and end walls, has connections for hoses on its rear side and fan nozzles at specific intervals on its front side. In the cleaning system's basic position, or the starting position of the cleaning process, the fan nozzles are perpendicular to the ceiling wall of the container's interior. After the cleaning process has started, the upper horizontal cleaning tube with the fan nozzles attached to it is moved via the two upper deflection shafts, so that the fan nozzles are now rotated 45 degrees in the forward direction. The feed drive then moves the cleaning system through the container to a defined distance from the end wall, where the cleaning system stops. After reaching the end wall, the upper cleaning tube, which is mounted horizontally on the toothed belts, moves towards the end wall.The cleaning tube with the fan nozzles swivels 90 degrees towards the front wall and then moves downwards from the upper starting position along the front wall to the end position. This means that the front wall cleaning begins with the ceiling nozzle moving via the belt drive. The belt drive moves the ceiling nozzle parallel to the back wall, from the ceiling to the floor. Once the lower position is reached, the dispensing of the cleaning fluid stops.

[0030] In a second embodiment of partial device II, the two vertical conveyor belts, the two deflection shafts, and the associated drive unit are omitted. Linear technology is now used for the vertical movement of the upper horizontal cleaning tube, which is used to clean the ceiling and end wall. Linear technology is a sub-discipline of drive technology and includes mechanical components for performing translational movement. Advantageously, a single-axis drive system with two Y-coordination axes, running in the same direction and spaced parallel to each other, is chosen. Two linear units are used, which are attached to the frame of the cleaning system. The linear units have a profile rail guide with a toothed belt drive. One of the two linear units has a drive unit, preferably an electric drive unit.This linear unit is connected to the linear unit without a drive unit via a lower shaft. The two profile rail guides support a tool slide. The horizontal cleaning tube is mounted on the two tool slides. Using the linear units, the horizontal cleaning tube can be moved vertically from the upper starting position parallel to the end wall to the end position at the floor and back. The starting position is the ceiling wall, and the end position is the floor wall. This horizontal cleaning tube also features an actuator that rotates it around its longitudinal axis, allowing the fan nozzles to be rotated in both forward and reverse directions. The rotation angle of the upper horizontal cleaning tube, used for cleaning the ceiling and end wall, is at least 270 degrees.

[0031] The inventive cleaning system also allows for a drying process. The drying unit dries the cleaned interior surfaces and removes any standing water after the cleaning process, rinsing, or before or after the disinfectant application. The drying process begins when the blower, preferably a radial blower, is switched on. The blower supplies air to the drying unit's air nozzles. The drying unit comprises four tubes designed as drying nozzles, each with an air slot. The drying nozzles are equipped with connections for a blower and mounting brackets for attaching them to the vertical and horizontal rectangular tubes of the frame. During the drying process, the cleaning system returns to its starting position.The immediate drying of the container further increases the effectiveness and thus the utility of the innovative cleaning system. Once the cleaning system has reached its home position, the blower switches off and the guide and centering unit retracts the belt drives, so that the cleaning system no longer has contact with the side walls. After the centering unit has retracted to the frame, the lifting vehicle lifts the cleaning system out of the container, and the cleaning process is complete. In another cleaning process, the drying process either ends at the inner door surfaces of the container or begins there.

[0032] In the Fig. Section 7a illustrates several variations for loading a cleaning system into a vehicle and container. In the first variation, I, the cleaning system, which has a transport device under its frame, is transported using a pallet truck and placed on the loading platform of a vehicle for interior cleaning. The cleaning process begins, as previously described, with the centering of the cleaning system, followed by the cleaning operation. For this, the cleaning system moves along the floor wall to the end wall and back. Interior door cleaning is not included in variation I.

[0033] In Variant II, however, interior door cleaning is provided. The cleaning system, along with its transport device, is mounted on the forklift pockets of a pallet truck. Unlike Variant I, the pallet truck does not place the cleaning system on the loading platform of a container, but instead remains stationary with the cleaning system between the open doors. To achieve this, the pallet truck positions the cleaning system at the height of the loading platform edge and laterally between the doors. The cleaning system has a cleaning unit on each side for cleaning the doors. These two cleaning units can move parallel to each other along the interior door surfaces from top to bottom. The two cleaning units for the interior door surfaces are technically identical to the cleaning unit for the front wall, as seen in Part II.The cleaning unit of the second part of the device consists of a horizontal cleaning tube that can move from top to bottom along the inside of the door via conveyor belts. After cleaning the inner door surfaces, the two side cleaning units are switched off, and the cleaning of the container's interior begins. If the cleaning system is located on a loading and unloading platform, it can now move independently from the door gap into the interior.

[0034] The next loading variant includes interior door cleaning. Therefore, the cleaning system is located on a loading and unloading platform. This platform is equipped with a transport device for a forklift. The forklift can thus transport the cleaning system, which is positioned on the platform. The forklift drives the cleaning system to the front of the open doors and positions it at the level of the loading platform and between the open doors. The gap between the loading and unloading platform and the loading platform is bridged by two ramps. The cleaning system can now move independently from the loading and unloading platform to the loading platform. During this movement, the cleaning system cleans the interior door surfaces, specifically using the cleaning unit of component I, which is designed for the interior side walls of a container.The two additional, lateral partial devices II of the cleaning unit are not required in this configuration. Before the cleaning process, the door leaves are secured to the loading and unloading platform using clamps, preferably gate catches that allow for easy locking and unlocking of the door leaves. The same catches attached to the vehicle or container can be used as gate catches. Securing the doors is necessary to maintain their open position during the cleaning process. Once the cleaning system is inside a container, the cleaning process begins with centering the cleaning system, followed by the cleaning process itself. Variant III is considered the preferred configuration for a container with a cleaning system.

[0035] Another loading method is similar to the previous one. In this method, the cleaning system is lowered by a forklift truck onto a stationary scissor lift with an integrated loading and unloading platform. Scissor lifts can be used where parking bays for containers are provided. A container is then parked backwards in front of the scissor lift. The scissor lift automatically adjusts the height of the cleaning system to the edge of the loading area. Cleaning the interior door surfaces begins as described in the previous loading procedure.

[0036] Fig. Figure 7b shows a loading system for a cleaning unit in which the scissor lift is not stationary but mounted on a mobile base. This allows the cleaning unit to be used at any location within a parked container. The mobile base is designed to house not only the cleaning unit, which sits on the loading and unloading platform of the scissor lift, but also a supply system. This supply system consists of a water and power supply, creating a self-contained cleaning unit. A treatment system for contaminated cleaning fluid is also integrated into the mobile base. This mobile base can be designed as a trailer, making the cleaning unit easily portable and usable at any location.

[0037] An example of a cleaning process flow is described below.

[0038] In practice, it's possible to begin the cleaning process for a container with the doors. To enable cleaning the inside of the doors, the cleaning system must be positioned in front of the open doors at the height of the loading platform edge and a specific lateral distance from the doors before cleaning can begin. Positioning is achieved using sensors located on the loading and unloading platform. These sensors can use ultrasonic or laser technology, which transmits the collected data to the automation system for further processing. Among other things, the dimensions of the container's interior and the position between the open doors are determined. A camera records the level of soiling before and after cleaning. The data is analyzed by a computer program to adjust the cleaning or washing program for the next cleaning cycle.In this way, the cleaning system learns over the long term, through machine learning, how to clean efficiently and, above all, in a resource-conserving manner. Further parameters such as the temperature of the cleaning fluid, the interior, and the environment are determined. Flow measurements regulate the supply of water, cleaning fluid, and disinfectant. An entry and exit ramp is to be installed between the loading and unloading platform, on which the cleaning system stands, and the floor wall of the container's cargo space. Sensors ensure the optimal positioning of the cleaning system for entering the space between the doors. The doors are secured to stays located on the loading and unloading platform. Cleaning of the inner door surfaces begins as the cleaning system passes over the entry and exit ramp.The loading ramp features two vertical cleaning pipes attached to the cleaning system, each equipped with fan nozzles for cleaning the side surfaces. All fan nozzles on the cleaning pipes are angled at 45 degrees in the forward direction of travel. Once the cleaning system reaches the loading platform, the following procedure for cleaning the interior begins.

[0039] According to the invention, the stated problem is solved by a method for cleaning the surfaces of an interior space, in particular of a vehicle and / or container, with the features of claim 12.

[0040] The method for cleaning the surfaces of an interior, in particular of a vehicle and / or container, consists of using the self-propelled cleaning system according to one of claims 1 to 11 and carrying out the cleaning with the following process steps: The first step is to place the cleaning system on a transportable loading / unloading platform and position it so that the front of the cleaning system faces the end wall of an interior space. The second step is to position the loading / unloading platform with the cleaning system in front of the open doors of an interior space, using sensors, at the height of the loading area edge and with equal lateral distance to both doors, with the two doors being detachably attached to the loading / unloading platform. The third step is to connect the cleaning system to a liquid source via a liquid supply line and to an electrical power source via an electrical cable. The fourth step is to install an entry / exit ramp between the loading / unloading platform and the loading area edge.The fifth process step is to clean the inner door surfaces as the cleaning system passes over the entry and exit ramp using the vertical cleaning tubes equipped with fan nozzles, and to adjust all fan nozzles in the forward direction towards the inner door surfaces to be cleaned, preferably at a 45-degree angle. The sixth process step is to center the cleaning system upon reaching the edge of the loading area using the lifting device and centering unit, and to extend the toothed belt drives laterally. Upon contact of the toothed belt drives with the side walls of the interior, cleaning of the floor and ceiling walls is to begin using the horizontal cleaning tubes equipped with fan nozzles, and to adjust all fan nozzles in the forward direction towards the floor and ceiling walls to be cleaned, preferably at a 45-degree angle.The seventh process step is for the drive unit to move the cleaning system through the interior to a defined distance from the end wall. The eighth process step, upon reaching the end wall, is to stop cleaning the side walls and the bottom wall, and to start cleaning the end wall with the upper horizontal cleaning tube. The horizontal cleaning tube then moves down along the end wall to the bottom wall. The ninth process step, upon reaching the bottom wall, is to stop cleaning the end wall and start the contact time for the cleaning fluid. The tenth process step is for the interior surfaces to be rinsed with cleaned water after the contact time has elapsed. The horizontal cleaning tube begins the rinsing process and moves upwards along the end wall to the ceiling wall.The eleventh process step, upon reaching the ceiling wall, is to tilt all the fan nozzles of the cleaning tubes 90 degrees in the reverse direction and begin the rinsing process for the side walls of the floor and ceiling. The drive unit of the traversing unit moves the cleaning system through the interior to the loading and unloading platform. The twelfth process step, upon reaching the inner door surfaces, is to stop rinsing the floor and ceiling walls and continue only rinsing the inner door surfaces until the cleaning system reaches its end and start position on the loading and unloading platform. The thirteenth process step, upon reaching the end and start position, is for the cleaning system to start the drying process by switching on the blower and tilting all the fan nozzles of the cleaning tubes 90 degrees in the forward direction.The fourteenth process step is to dry the inner door surfaces as the cleaning system passes over the entry and exit ramps using the vertical cleaning pipes equipped with fan nozzles. The fifteenth process step is to dry the floor and ceiling walls by activating the horizontal cleaning pipes, also equipped with fan nozzles, upon reaching the edge of the cargo area. The sixteenth process step is for the drive unit to move the cleaning system through the interior to a predetermined distance from the end wall. Upon reaching the end wall, the drying of the side walls and floor wall is stopped, the horizontal cleaning pipe is activated to dry the end wall, and the vertical cleaning pipe is moved downwards along the end wall to the floor wall.The seventeenth process step, upon reaching the floor wall, is to stop drying the end wall and start disinfection, beginning the disinfection of the interior surfaces with disinfectant, with the horizontal cleaning tube moving upwards along the end wall to the ceiling wall. The eighteenth process step, upon reaching the ceiling wall, is to tilt all fan nozzles of the cleaning tubes 90 degrees in the reverse direction and begin disinfection of the side walls, floor, and ceiling walls, with the drive unit of the traversing unit moving the cleaning system through the interior to the loading and unloading platform. The nineteenth process step, upon reaching the inner door surfaces, is to stop disinfecting the floor and ceiling walls and continue only disinfecting the inner door surfaces until the cleaning system reaches the end and start position on the loading and unloading platform, at which point the guide and...Retract the centering unit and decouple all supply systems.

[0041] The procedure for cleaning interiors is, of course, not limited to the aforementioned process flow, but can also be adapted to other needs. For example, a cleaning fluid mixed with disinfectant can be used, or the interior can be dried in both forward and reverse directions, or the inner door surfaces can be omitted, allowing cleaning to begin directly at the edge of the cargo area, or the cleaning process with cleaning fluid can be repeated twice, etc., to name just a few examples of possible variations for cleaning an interior. Furthermore, it should be mentioned that in an advantageous design of the cleaning system, the interior surfaces can be disinfected as the cleaning system moves out of the interior. Separate nozzles, arranged on the cleaning system, can be used for disinfection in the reverse direction.During the reverse movement of the cleaning system, the water (cleaning fluid) and moisture from the interior surfaces are blown towards the exit through the drying nozzles. Disinfection nozzles are located downstream of the drying nozzles during this reverse movement. This means that while the interior surfaces are being dried towards the exit, they are simultaneously sprayed with disinfectant on the interior side.

[0042] A control program therefore contains a variety of different cleaning programs and thus cleaning sequences. The standard cleaning program was previously described. The standard program is based on the standard cleaning system, according to the base frame, which does not include a separate drying module. Fig. 5. Drying takes place via the vertical and horizontal cleaning tubes of sub-devices I and II of the cleaning unit, using the existing blower. In an extended version of the cleaning system, a separate drying module is included, according to the Fig. 5, on the base frame of assembly I. In an alternative version of the cleaning system, the cleaning tubes of assembly IV, used in combination for cleaning and drying, are not movable on the base frame, according to the Fig. 1a, but on the toothed belt drives of the guide and centering unit of assembly III, according to the Fig. 1b, ordered.

[0043] Due to its diverse range of applications, the cleaning system according to the invention can be used for a variety of different interior fittings of containers and is not limited to just one type of refrigerated trailer.

[0044] Preferred embodiments and further developments of the invention are set forth in the dependent claims. The advantages and features can be found in the general description of the invention, the description of the exemplary embodiments, and the accompanying drawings. Such an inventive cleaning system achieves greater efficiency and a higher cleaning quality that far exceeds all legal requirements.

[0045] Furthermore, the invention is not limited to the illustrated and described embodiment, but also includes all embodiments and means that have the same effect in the sense of the invention. Exemplary embodiment of the invention

[0046] A specific embodiment of the invention is shown in the drawing of the Fig. Figure 6 is shown purely schematically. Further details and embodiments of the invention can be found in the accompanying description and the drawings of the Fig. Remove 1 to 5 and 7. It shows: Fig. 1a a perspective view of the first assembly I, the inventive base frame in preferred oblique view from the side and from behind, and Fig. 1b a perspective view of the first assembly I, the frame, combined with the third assembly III, the guide and centering unit and the fourth assembly IV, the sub-device I of the cleaning unit in preferred oblique views from the side and from the front, and Fig. 2 a perspective view of the second assembly II, the traversing unit according to the invention, preferably in oblique view from the side and from the front, and Fig. 3 a perspective view of the third assembly III, the guide and centering unit according to the invention together with lifting device, preferably in oblique view from the side and from behind, and Fig. 4 a perspective view of the fourth assembly IV, the cleaning unit according to the invention, preferably in oblique view from the side and from the front, and Fig. 5 a perspective view of the fifth assembly V, the drying unit according to the invention, preferably in oblique view from the side and from the front, and Fig. 6 a schematic representation of the cleaning system according to the invention, preferably in oblique view from the side and from the front, and Fig. 7a schematically shows the use of the cleaning system in a truck body and refrigerated container, and Fig. Figure 7b shows a schematic representation of the transport of a cleaning system on a mobile base.

[0047] The Fig. Figure 1a shows the base of the modular cleaning system 1, a frame 6 in perspective view. The frame 6 supports modules, each consisting of individual modules that form five self-contained assemblies I - V. Each module can be mounted and / or replaced on the frame 6 independently of the other modules. The individual assemblies II 7, III 8, IV 9, V 10, consisting of the traversing unit 11, the guiding and centering unit 12, the cleaning unit 13, the drying unit 14, and the lifting device 12.1, are mounted on the frame 6, which represents the first assembly I 6.1, as shown in the following figures. Fig. 2, Fig. 3, Fig. 4, Fig. 5 shown, mounted. The frame 6, completed with assemblies II - V, forms the embodiment of the cleaning system 1, as shown in the Fig. 6 shown, where the application of cleaning system 1 of the Fig. 7a, Fig. 7b can be seen.

[0048] The frame 6 is constructed as a welded structure. It consists of square and rectangular tubes 20, forming a geometric tube structure 19. This tube structure 19, made of square and rectangular tubes 20, essentially forms two planes: a horizontal plane 21, which forms the lower plane or bottom surface 21 of the frame 6, and a vertical plane 22, which forms the front surface 63 of the frame 6. The vertical plane 22 is at a 90-degree angle to the horizontal plane 21 of the horizontal tube 20.2. The vertical plane 22 is supported by two inclined supports 23.1, 23.2, acting as diagonal braces. One end of the braces is located in the upper region of the two vertical tubes 20.5, 20.6 of the vertical plane 22, and the other end is connected to the end 24 of the horizontal plane 21, to the two horizontal tubes 20.1, 20.3. The two planes 21, 22 thus form an "L-shaped" frame 6.

[0049] In this specific embodiment, four horizontal rectangular tubes 20.1, 20.2, 20.3, 20.4 of the horizontal plane 21 form a base frame 26, wherein two tubes 20.2, 20.4 of the base frame 26 run transversely to the direction of travel 25 and two tubes 20.1, 20.3 run longitudinally to the direction of travel 25 of the cleaning system 1. Further square and rectangular tubes 20.7, 20.8, 20.9, 20.10 are arranged in this base frame 26. These square and rectangular tubes 20.7, 20.8, 20.9, 20.10 are also located in the horizontal plane 21 and are arranged parallel to each other and spaced apart from the longitudinal tubes 20.1, 20.3 of the base frame 26, running in the forward and reverse directions 25. Some of these square and rectangular tubes 20.7, 20.8, 20.9, 20.10 are equipped with threaded nuts (not shown) for fastening the individual assemblies II 7, III 8, IV 9, V 10. Furthermore, the mounting points 27.1, 27.2 are located on the tubes 20.1, 20.3 of the base frame 26.2, 27.3, 27.4 for the flange bearing pairs 66.1 - 66.4 of the toothed belt drives 65.1, 65.2 for the guide and centering unit 12 of assembly III 8. The longitudinal tubes 20.1, 20.3 of the base frame 26 are thus the supports for the toothed belt drives 65.1, 65.2 of the guide and centering unit 12, see . Fig. 3.

[0050] The next tubes 20.7, 20.8, spaced parallel to the tubes 20.1, 20.3 of the base frame 26, serve as supports for receiving assembly II 7, i.e., the traversing unit 11. The traversing unit 11 is attached to the tubes 20.7, 20.8 by means of screw connections 54.1 - 54.4 of fasteners, preferably pairs of flat bars 53.1 - 53.4. The fastening points 45.1 - 45.4 for the flat bar pairs 53.1 - 53.4 are located laterally on the right and left sides of the tubes 20.7, 20.8, whereby the traversing unit 11 is positioned below the frame 6. Further details can be found in the Fig. 2. The drive of the traversing unit 11, consisting of a geared motor 52, is screwed to a mounting plate 40.2, which is located on the horizontal tube 20.4 of the base frame 26. The distance 30.1, 30.2 between the parallel and longitudinally extending tubes 20.1, 20.3 of the base frame 26 and the longitudinally extending tubes 20.7, 20.8, which serve to attach the traversing unit 11, is approximately 1 / 6 to 1 / 8 of the width 28 of the frame 6. The width 28 of the frame 6 or of the base frame 26 runs transversely to the direction of travel 25 of the cleaning system 1 and is approximately the width 161 of the opening 160 of the interior 4 of a refrigerated container 3, see Fig. 7a, less the dimensions for the guide and centering unit 12 arranged laterally on the base frame 26, see below. Fig. 3.

[0051] In the space 29 between the two parallel-spaced tubes 20.7, 20.8, which form the supports for the traversing unit 11, two further tubes 20.9, 20.10 are arranged parallel to the supports and thus running longitudinally. These two tubes 20.9, 20.10 serve as supports for receiving the lifting device 81; further details can be found in the Fig. 3. The distance 31.1, 31.2 between the tubes 20.7, 20.8, which are supports of the traversing unit 11, and the tubes 20.9, 20.10, which are supports of the lifting device 81, is approximately 1 / 6 to 1 / 8 of the width 28 of the frame 6. Thus, viewed in the transverse direction of the frame 6, a distance 32 is obtained between the inner tubes 20.9, 20.10 of the base frame 26. This distance is approximately 2 / 6 to 4 / 8 of the width 28 of the frame 6. Furthermore, four supports 33.1, 33.2, 33.3, 33.4, spaced 25 apart in the longitudinal direction, are arranged on the upper side of the tubes 20.9, 20.10. These supports 33.1, 33.2, 33.3, 33.4 serve to fasten lifting cylinders 82.1 - 82.8, preferably consisting of electric cylinders for the lifting device 81, see [reference to relevant section]. Fig. 3.

[0052] In this specific embodiment, two vertical rectangular tubes 20.5, 20.6, together with the upper horizontal rectangular tube 34, which has the same length as the lower rectangular tube 20.2, form a vertical plane 22. That is, the two vertical tubes 20.5, 20.6 are connected in the upper region 35 to the upper horizontal rectangular tube 34 and in the lower region 36 to the horizontal rectangular tube 20.2 from the base frame 26. The vertical plane 22 is thus framed by the two vertical tubes 20.5, 20.6 and the two horizontal tubes 20.5, 20.6, forming a vertical support structure 37 in the shape of a rectangle. The two vertical tubes 20.5, 20.5 are arranged perpendicularly at the ends of tube 20.2 in the lower region 36, so that all internal angles in the frame 37 are 90 degrees and thus form the vertical, right-angled plane 22. Viewed in the forward direction 25, the vertical plane 22 or 20.5 forms the vertical plane 22.The frame 37 forms the front 38 of the frame 6. The vertical plane 22 of the frame 37 is connected to the horizontal base frames 26 via diagonal supports 23.1, 23.2. The connection is made at the rear of the frame 37. The frame 37 can be reinforced by a diagonal cross 162, which is welded in the corners of the rectangle, see . Fig. 6. The vertical tubes 20.5, 20.6 are connected to the horizontal tubes 20.1, 20.3 via supports 23.1, 23.2. The supports 23.1, 23.2 form the side section of the frame 6.

[0053] Furthermore, the two vertical tubes 20.5, 20.6 serve to attach assembly IV 9 of the cleaning unit 13 to the frame 6, the complete cleaning unit 13 consisting of two sub-devices 13.1, 13.2. The first sub-device 13.1 is responsible for cleaning the side walls 15.1, 15.2 and the bottom wall 16, and the second sub-device 13.2 for the ceiling 17 and the end wall 18. The first sub-device 13.1 is attached to the outside of the two vertical tubes 20.5, 20.6, respectively, on the side facing side wall I, II 15.1, 15.2 of the interior 4 of the container 3. The same applies to the lower horizontal tube 20.2. It is attached to the outside of the horizontal tube 20.2, etc. on the side facing the bottom wall 16 of the interior 4. Distributed along the length of the pipes 20.2, 20.5, 20.6, twelve support blocks 91.1 - 91.12 are located at specific intervals, one each for cleaning pipe 90.1, 90.2, 90.3. Four bearing blocks 91.1 - 91.4, 91.5 - 91.8, 91.9 - 91.12 are arranged. For the twelve bearing blocks 91.1 - 91.12 in total, four fastening points are preferably provided for each of the two vertical pipes 20.5, 20.6 and the horizontal pipe 20.2, for a total of twelve fastening points for one pipe 20.2, 20.5, 20.6. For clarity, the twelve fastening points are shown in the diagram. Fig. 1a, however, is only marked with three reference numerals: 39.1, 39.2, 39.3. The bearing blocks 91.1–91.12 accommodate the rotatable cleaning tubes 90.1–90.3, which are used for cleaning the side walls 15.1, 15.2 and the bottom wall 16; see [reference to be added]. Fig. 4.

[0054] The second sub-device 13.2 relates to the cleaning of the ceiling 17 and end wall 18. The second sub-device 13.2 is attached at the designated points on the lower and upper horizontal tubes 20.2, 34. The lower horizontal tube 20.2, as the support for the sub-device 13.2, has a designated mounting point 40.1 for a drive geared motor 101, which consists of a welded-on plate. At each of the lateral ends of the lower horizontal tube 20.2, there is a mounting point 41.1, 41.2 for a bearing bracket 102.3, 102.4, for supporting the lower drive shaft 99 for the belt drive 98.1, 98.2, preferably a toothed belt drive (see figure). Fig. 4, arranged. Likewise, two mounting points 42.1, 42.2 are located on the upper horizontal tube 34. One mounting point 42.1, 42.2 is located at the end of the upper horizontal tube 34 for supporting the two upper deflection shafts 100.1, 110.2 for the belt drive 98.1, 98.2 of the front-facing partial device 13.2 of the cleaning unit 13, see Fig. 4.

[0055] Next, the attachment points of assembly V 10 on the frame 37 must be specified. Assembly V 10 relates to the drying unit 14. The drying unit 14 is designed with several drying nozzles 113.1 - 113.4, preferably four drying nozzles 113.1 - 113.4. The drying nozzles 113.1 - 113.4 are tubes designed with an elongated air slot 114.1 - 114.4 and function as nozzles, according to the Fig. 5. Each of the four drying nozzles 113.1 - 113.4 is equipped with three mounting brackets along its entire length, whereby, for the sake of clarity, only one reference numeral 115.1, 115.2, 115.3, 115.4 is used for every three mounting brackets. For these three mounting brackets 115.1, 115.2, 115.3 per drying nozzle 113.1, 113.2, 113.3, 113.4, three mounting points 43.1, 43.2, 43.3, 43.4 are provided on the two vertical tubes 20.5, 20.6 and the two horizontal tubes 20.2, 34 of the support structure 37. These mounting points 43.1, 43.2, 43.3, 43.4 of the drying unit 14 are located between the mounting points 39.1, 39.2, 39.3 of the cleaning unit 13. The drying nozzles 113.1 - 113.4 of the drying unit 14 are supplied with air via a blower 117 located centrally on the frame 6, see Fig. 5. The blower 117 has a base 118 which is attached to a console 119. The console 119 serves as a support and connector for the blower 117 to the frame 6. The console 119 is designed such that it can in turn be screwed onto the horizontal tubes 20.7, 20.8 of the top 87 of the base frame 26 at fastening points.

[0056] Below the base frame 26, on the underside 88, is a transport device 129 for transporting the cleaning system 1 with a transport vehicle, preferably a forklift 140, see Fig. 7a, present. The transport device 129 consists of two parallel rectangular tubes 163.1, 163.2. The two rectangular tubes 163.1, 163.2 have cross-sectional dimensions corresponding to those of the standard transport forks (not shown) of a forklift 140. The parallel spacing of the rectangular tubes 163.1, 163.2 corresponds to the distance 32 between the two horizontal tubes 20.9, 20.10, which run in the forward direction 25.

[0057] The inwardly facing fastening points 44.1, 44.2 for the cleaning tank and disinfection tank 164 are located on the right and left diagonal struts 23.1, 23.2 of the frame 6, wherein the cleaning tank 150 and the disinfection tank 164 preferably consist of two containers, see Fig. 6 u. Fig. 7b.

[0058] The Fig. Figure 1b shows in schematic and perspective representation the first assembly I 6.1, the frame 6, combined with the third assembly III 8, the guide and centering unit 12 and the fourth assembly IV 9, the sub-device I 13.1 of the cleaning unit 13, in preferred view obliquely from the side and from the front.

[0059] Contrary to the intended fastening points 39.1, 39.2 for the bearing blocks 91.1 - 91.8 of the two vertical cleaning pipes 90.1, 90.2 on the two vertical rectangular tubes 20.5, 20.6 of the frame 6, according to the Fig. 1a, the two vertical cleaning tubes 90.1, 90.2 are now arranged on the two toothed belt drives 65.1, 65.2 of the guide and centering unit 12. The toothed belt drives 65.1, 65.2 are, as shown from the Fig. As shown in Figure 3, the two toothed belt drives 65.1 and 65.2 are movably arranged on the frame 6 by means of flanged bearing pairs. The two toothed belt drives 65.1 and 65.2 now support the two vertical cleaning tubes 90.1 and 90.2. For this purpose, each toothed belt drive 65.1 and 65.2 is equipped with a linkage 130.1 and 130.2 formed on the toothed belt drive 65.1 and 65.2. A linkage 130.1 and 130.2 consists of a horizontal base rail 131.1 and 131.2 (opposite side) and a vertical rail 132.1 and 132.2 (adjacent side) arranged at one end (I 133), while a diagonal rail 135.1 and 135.2 (hypotenuse) is connected to the other end (II 134). The linkage 130.1, 130.2 forms a right-angled triangle 136.1, 136.2, which is reinforced by a horizontal crossbar 137.1, 137.2. The crossbar 137.1, 137.2 is positioned approximately halfway along the opposite side, i.e., the median of the right-angled triangle 136.1, 136.2. A base rail 131.1 is located on a side guide 74.1 of one of the toothed belt drives 65.1, while the other base rail 131.2 is located on the side guide 74.2 of the other toothed belt drive 65.2. The surfaces 138.1, 138.2 of the two side guides 74.1, 74.2 form a horizontal plane in which the base rail 131.1, 131.2 is mounted. The two vertical rails 132.1, 132.2 are perpendicular to the horizontal plane and thus perpendicular to the surfaces 138.1, 138.2 of the side guides 74.1, 74.2. One cleaning tube 90.2 is arranged on one vertical rail 132.1 and the other cleaning tube 90.1 is arranged on the other vertical rail 132.2. The fastening of the two cleaning tubes 90.1, 90.2 is identical to the fastening of the cleaning tubes 90.1, 90.2 to the frame 6, according to the . Fig. 1a u. Fig. 4. The adjustment can be made within an angular range of up to 120 degrees. That is, the two cleaning tubes 90.1, 90.2 are rotatably mounted on the two vertical bars 132.1, 132.2 and can be adjusted about their vertical longitudinal axis 166, for example, by means of an electric / pneumatic drive system, preferably a motion cylinder consisting of an electric cylinder 96.1, 96.2. Alternatively, a servo motor, as a special type of electric motor, can be used. This motor allows control of the angular position of its motor shaft and thus control of the angular position of the cleaning tubes 90.1, 90.2, 90.3. These consist of an electric motor and are additionally equipped with a position sensor.The rotational position of the motor shaft, as determined by the sensor, is continuously transmitted to a control electronics unit, usually located outside the actual motor. This unit, known as a servo controller, regulates the motor's movement in a closed-loop control system according to one or more adjustable setpoints, such as the desired angular position of the shaft. An electric stepper motor can also be used in a similarly targeted manner, without requiring sensors or control loops.

[0060] Other drives or actuators are also conceivable. The arrangement of the two cleaning tubes 90.1, 90.2 on the two toothed belt drives 65.1, 65.2 of the guide and centering unit 12 has the advantage that when the toothed belt drives 65.1, 65.2 extend laterally, the cleaning tubes 90.1, 90.2 also extend until the toothed belt drives 65.1, 65.2 make contact with the side walls 15.1, 15.2 of an interior space 4. The fan nozzles 94.1, 94.2 arranged on the cleaning tubes 90.1, 90.2 are shown in the figure below. Fig. 4. Thus, when the toothed belt drives 65.1, 65.2 are extended, they are positioned directly or at a predetermined distance in front of the surfaces of the side walls 15.1, 15.2 to be cleaned. The predetermined distance of a cleaning tube 90.1, 90.2 to the side wall 15.1, 15.2 is determined by the positioning of the linkage 130.1, 130.2 on the toothed belt drive 65.1, 65.2. After completion of a cleaning and / or drying process, the cleaning tubes 90.1, 90.2 are retracted from the side walls 15.1, 15.2 by retracting the toothed belt drives 65.1, 65.2. The distance between the fan nozzles 94.1, 94.2 and the side walls 15.1, 15.2 is always constant when the toothed belt drives 65.1, 65.2 are extended, regardless of whether the cleaning system 1 is positioned 100% centrally inside a container or exhibits deviations. Furthermore, in the Fig. Figure 1b shows an arrangement of linear units 124.1, 124.2 on the vertical rectangular tubes 20.5, 20.6 of the frame 6. The use of linear units 124.1, 124.2 instead of the conveyor belt technology (see Figure 1b) is shown. Fig. 4) represents a further advantageous embodiment of the partial device II 13.2, the cleaning unit 13. It is technically irrelevant that the upper horizontal rectangular tube 34 does not connect the vertical rectangular tubes 20.5, 20.6 at their ends. What is important is that the horizontal cleaning tube 97 is connected to the two tool slides 126.1, 126.2 of the two linear units 124.1, 124.2. The cleaning tube 97, which is rotatably mounted on the tool slides 126.1, 126.2, is also adjustable about its horizontal longitudinal axis 167 by means of an actuator within a rotational angle range 168 of up to 270 degrees. These are also part of the second embodiment of the partial device II 13.2 of the cleaning unit 13, which is used for cleaning and / or drying the ceiling 17 and the end wall 18. To avoid repetition, reference is made to the more detailed explanations of linear units 124.1 and 124.2 in the Fig. 4. Furthermore, for the sake of clarity, the other rectangular tubes required for arranging the other assemblies II 7, III 8 in the frame 6 have not been listed. These can, however, be found in the Fig. 1a can be viewed.

[0061] From the following Fig. 2 shows assembly II 7 of the traversing unit 11. For identical elements in the Fig. 2 to Fig. 7. Uniform reference symbols are used.

[0062] In the Fig. Figure 2 shows assembly II 7 with the inventive traversing unit 11 in perspective for illustration. The resulting Fig. 1a u. Fig. The reference symbols known from 1b are adopted analogously here.

[0063] The transport unit 11 has a drive unit 46.1, 46.2 for moving the cleaning system 1 in the forward and reverse directions 25. The drive unit 46.1, 46.2 consists of two conveyor belts 47.1, 47.2, two U-shaped housings 48.1, 48.2, at least six toothed belt pulleys 49.1 - 49.6, a drive shaft 50, a drive belt 51, a geared motor 52, two belt tensioning units 57.1, 57.2, and four pairs of flat iron bars 53.1 - 53.4 as fastening means, wherein the pairs of flat iron bars 53.1 - 53.4 are attached laterally to the support tubes 20.7, 20.8 of the frame 6 by means of screw fasteners 54.1 - 54.4, see Fig. 1a, to be assembled.

[0064] The two conveyor belts 47.1, 47.2 preferably consist of endless toothed belts. The toothed belts 47.1, 47.2 are used as a reliable circulating conveyor for slip-free drive in the forward and reverse directions 25 of the cleaning system 1. Each toothed belt 47.1, 47.2 is guided over at least two toothed belt pulleys 49.1 - 49.4 in a U-shaped housing 48.1, 48.2. The toothed belt 47.1 guided in the housing 48.1 is spaced parallel to the toothed belt 47.2 guided in the housing 48.2. The distance 56 between the toothed belts 47.1, 47.2 is determined by the predetermined spacing of the support tubes 20.7, 20.8 arranged in the frame 6. The parallel spacing 56 of the housings 48.1, 48.2 results in a two-sided design of the drive unit 46.1, 46.2, creating a double track 55.1, 55.2. Furthermore, two pairs of flat iron bars 53.1 - 53.4 are arranged on each U-shaped housing 48.1, 48.2. The flat iron bar pairs 53.1 - 53.The flat iron pairs 53.1–53.4 are attached laterally to the left and right sides of the housing 48.1, 48.2, preferably by means of screws (not shown). The length of the flat iron pairs 53.1–53.4 corresponds approximately to twice the side height of a housing 48.1, 48.2, causing the flat iron pairs 53.1–53.4 to project upwards beyond the housing 48.1, 48.2 and form free ends 58.1–58.4. The free ends 58.1–58.4 serve to be attached to the mounting points 45.1–45.4, which are located laterally on the support tubes 20.7, 20.8 of the frame 6. The attachment is preferably made using screws 54.1–54.4. Due to the arrangement of the flat iron pairs 53.1–53.4, the traversing unit 11 is positioned below the frame 6.

[0065] The conveyor belts 47.1, 47.2 are driven by a drive shaft 50, which connects the two spaced-apart housings 48.1, 48.2. The drive shaft 50 is perpendicular or transverse to the drive units 46.1, 46.2 in the same horizontal plane 21 of the base frame 26. Additionally, the drive shaft 50 can be mounted on the horizontal tube 20.4 via bearing blocks (not shown), see Figure 1. Fig. 1a, of the frame 6. The drive shaft 50 is driven by a geared motor 52, which has a drive belt 51, the drive belt 51 being guided over two toothed belt pulleys 49.5, 49.6. One toothed belt pulley 49.6 is located on the geared motor output shaft and the other toothed belt pulley 49.5 on the drive shaft 50. The geared motor 52 is screwed to a mounting plate 59 welded to the horizontal tube 20.4 using blind hole threads, see Fig. 1a.

[0066] The conveyor belts 47.1, 47.2, guided in the U-shaped housing 48.1, 48.2 of the drive unit 46.1, 46.2, run over a sliding plate 60.1, 60.2. The two sliding plates 60.1, 60.2 support the weight of the cleaning system 1 and distribute the weight evenly over their surface area. The sliding plates 60.1, 60.2 transmit the weight force F to the conveyor belt surface and thus to the bottom wall 16 of the interior 4 of a container 3. The conveyor belt width and length, or center distance 61, are determined by the conveyor belt surface area. Since it is also an object of the invention to achieve the lowest possible weight force for the cleaning system 1, the dimensions of the cleaning system 1 must also be kept as small as possible. The required bearing surface of the sliding plate 60.1, 60.2 is calculated using the weight force F resulting from the individual assemblies I - V, 6.1 - 10 and a container 164 filled with disinfectant.The calculated and therefore required contact area for the sliding plate 60.1, 60.2 determines the conveyor belt width 62.1, 62.2 and the conveyor belt length. The diameters of the toothed belt pulleys 49.1 - 49.4, the number of teeth on the toothed belt pulleys 49.1 - 49.4, and the transmission ratio are also taken into account when determining the conveyor belt length. The center distance 61 between the two toothed belt pulleys 49.1, 49.2 and between the two toothed belt pulleys 49.3, 49.4 is then derived from the calculated conveyor belt length. The center distance 61 may increase slightly due to the belt tensioning unit 57.1, 57.2, which is arranged on the housing 48.1, 48.2 of the drive unit 46.1, 46.2 in the forward direction 25. The center distance 61 of the toothed belt pulley 49.1 to the toothed belt pulley 49.2 of one drive unit 46.1 and of the toothed belt pulley 49.3 to the toothed belt pulley 49.4 of the other drive unit 46.2 is approximately 800mm to 1200mm, preferably approximately 1000mm.The conveyor belt width 62.1, 62.2 is approximately 25 mm to 45 mm, preferably 32 mm. The center distance 61 of the drive unit 46.1, 46.2 determines the length of the drive unit 46.1, 46.2 and thus the length of the base frame 6 in which the drive unit 46.1, 46.2 is mounted. The length of the base frame 6, in turn, determines the length of the cleaning system 1. Next, in the... Fig. 3 the guidance and centering unit 12 is considered.

[0067] From the Fig. Figure 3 shows assembly III 8 with the guide and centering unit 12 in a perspective view. The lifting device 81, which is part of assembly III 8, is also included in this figure. The Fig. 1a, Fig. 1b u. Fig. The two known reference symbols are adopted analogously here.

[0068] The guide and centering unit 12 is formed from two complete toothed belt drives 65.1, 65.2, two belt tensioning units 75.1, 75.2, four flange bearing pairs 66.1 - 66.4, two four-bar linkage chains 67.1, 67.2, two double-sided levers 68.1, 68.2, wherein a double-sided lever 68.1, 68.2 consists of a lever I 69.1, 69.2 and a connecting rod 70.1, 70.2, a linear guide 71 and a hydraulic or pneumatic drive cylinder 72, preferably an electric cylinder 72. The combination of a toothed belt drive 65.1, 65.2, a lever I 69.1, 69.2, a connecting rod 70.1, 70.2 and a linear unit 71 forms a four-bar linkage 67.1, 67.2.

[0069] A lifting device 81 consists of two lifting plates 83.1, 83.2, which are provided with ball rollers 84.1, 84.2, and of eight hydraulic or pneumatic drive cylinders 82.1 - 82.8 arranged thereon, preferably electric cylinders 82.1 - 82.8. A lifting unit 81 is thus a carrier of lifting cylinders 82.1 - 82.8 and ball rollers 84.1, 84.2. Each lifting plate 83.1, 83.2 consists of an elongated flat steel bar 120.1, 120.2 with a central web 85.1, 85.2, wherein the flat steel bar 120.1, 120.2 is equipped laterally on the left and right sides in the plane of the flat steel bar 120.1, 120.2 with four projecting flat supports 121.1 - 121.8 per lifting plate 83.1, 83.2. The supports 121.1 - 121.8 are spaced 25° apart in the longitudinal direction and a lifting cylinder 82.1 - 82.8 is arranged per support 121.1 - 121.8. The ball rollers 84.1, 84.2 are located to the left and right of the longitudinally executed central web 85.1, 85.2 of a lifting plate 83.1, 83.2 arranged, with seven ball rollers 84.1, 84.2 provided on each side.

[0070] The guide and centering unit 12 travels with the entire cleaning system 1 in forward and reverse directions 25 on the horizontal plane of the loading platform 141 of a vehicle 2 or container 3, wherein the toothed belt drives 65.1, 65.2 are not arranged below the frame 6 like the drive units 46.1, 46.2, but laterally on the frame 6 in a horizontal direction to the direction of travel 25, and thus guide the cleaning system 1 along the vertical side walls I, II 15.1, 15.2 of the interior 4 of a container 3. Therefore, the guide and centering unit 12 consists, among other things, of a tube 20.1, 20.3 to the left and right of the horizontal tubes 20.1, 20.3 of the base frame 26 of the frame 6, see Fig. 1a, arranged toothed belt drive 65.1, 65.2, see Fig. 6. A toothed belt drive 65.1, 65.2 here refers to the complete technical implementation of a toothed belt 77.1, 77.2 running over toothed belt pulleys 76.1 - 76.4, wherein the toothed belt pulleys 76.1 - 76.4, arranged between the side guides 74.1 - 74.4, have a specific center distance 73. The axes 86.1 - 86.4 of the toothed belt pulleys 76.1 - 76.4 of the toothed belt drives 65.1, 65.2 are perpendicular to the horizontal axes 59.1 - 59.4 of the toothed belt pulleys 49.1, 49.4 of the drive units 46.1, 46.2. The conveyor belts 77.1, 77.2 of the guide and centering unit 12, preferably consisting of toothed belts, are thus arranged pivoted by 90 degrees relative to the conveyor belts 47.1, 47.2 of the traversing unit 11. That is, the toothed belt drives 65.1, 65.2 are still spaced parallel to the drive units 46.1, 46.2 and run in the same direction. The drive units 46.1, 46.The two toothed belt drives 65.1 and 65.2 are located on the horizontal plane 21 to the bottom wall 16, also referred to as the "XY" plane, where "X" is the direction of travel 25 of the cleaning system 1 on the longitudinal plane of a vehicle 2 or container 3, "Y" is the width 161 of the interior 4 of a container 3, and "Z" represents the height of the interior 4 of a container 3. The two toothed belt drives 65.1 and 65.2 are each arranged in a lateral perpendicular plane to the side walls I, II 15.1, 15.2, also referred to as the "XZ" plane. The front 92 of the frame 6, however, is located in the vertical plane 22 parallel to the end wall 18, i.e., in the "YZ" plane.

[0071] The center distance 73 of the toothed belt pulley 76.1 to the toothed belt pulley 76.2 of one toothed belt drive 65.1, or of the toothed belt pulley 76.3 to the toothed belt pulley 76.4 of the other toothed belt drive 65.2 of the guide unit 12, corresponds to the center distance 61 of the toothed belt pulleys 49.1 to 49.2 and 49.3 to 49.4 of the conveyor belts 47.1, 47.2 of the drive unit 46.1, 46.2, see Fig. 2. The center distance 73 may increase slightly due to the belt tensioning unit 75.1, 75.2, which is arranged in the housing 111.1, 111.2 of the toothed belt drives 65.1, 65.2 in the reverse direction 25.

[0072] A complete toothed belt drive 65.1, 65.2 each has a front 66.2, 66.4 and a rear 66.1, 66.3 flange bearing pair 66.1 - 66.4, which, acting as levers, are arranged laterally on the outer sides of the side guides 74.1 - 74.4. All flange bearing pairs 66.1 - 66.4 point in the same oblique direction towards the longitudinally extending, horizontal rectangular tubes 20.1, 20.3. The two rear flange bearing pairs 66.1, 66.3 each consist of two parallel flanges of equal length. The free ends 78.1 - 78.4 of the flange bearing pairs 66.1 - 66.4 are rotatably mounted at the attachment points 27.1 - 27.4 provided on the frame 6, see Figure 1. Fig. 1a. The distance 79.1, 79.2 between the flanges results from the width 80.1, 80.2 of the toothed belt drive 65.1, 65.2. In the front flange bearing pair 66.2, 66.4, viewed in the forward direction 25, the upper flange is designed as a longer lever 69.1, 69.2. A connecting rod 70.1, 70.2 is rotatably connected to the opposite side of the longer lever 69.1, 69.2 of the flange bearing pairs 66.2, 66.4, which is arranged on the upper side guide 74.1, 74.3 of the housing 111.1, 111.2. The longer lever 69.1, 69.2, together with the connected connecting rod 70.1, 70.2, forms a two-sided lever 68.1, 68.2. The other end of the connecting rod 70.1, 70.2 is connected to a linear guide 71. The linear guide 71 is driven by an electric cylinder 72. The linear guide 71 is attached centrally to the horizontal tube 20.4 of the base frame 26 on the frame 6.

[0073] The lifting device 81 shown in this figure is attached below the frame 6 to the inner tubes 20.9, 20.10 of the base frame 26, which run horizontally in the forward and reverse directions of travel 25. The lifting device 81 consists of hydraulic or pneumatic lifting cylinders 82.1 - 82.8, preferably eight electric cylinders 82.1 - 82.8, at the ends of whose piston rods two lifting plates 83.1, 83.2 are attached. The lifting plates 83.1, 83.2 are made of flat steel, which is reinforced centrally in the longitudinal direction by a vertically welded flat steel, forming a web 85.1, 85.2. The reinforcement creates an inverted ⊥ profile. To the right and left of the vertical reinforcement, i.e., the central web 85.1, 85.2 of the lifting plates 83.1, 83.2, ball rollers 84.1 - 84.4 are embedded. The ball rollers 84.1 - 84.The four components are arranged in a row and allow free movement of the cleaning system 1 in the horizontal plane 21, i.e., parallel to the floor wall 16 of the interior 4, and ensure, with the aid of the toothed belt drives 65.1, 65.2 of the centering unit 12, that the cleaning system 1 is positioned in the direction of travel 25. Next, in the... Fig. 4 the cleaning unit 13 is considered.

[0074] The Fig. Figure 4 shows assembly IV 9 with cleaning unit 13 in perspective view. The components from the Fig. 1a, Fig. 1b, Fig. Reference symbols 2 and 3 are adopted analogously here.

[0075] The complete cleaning unit 13 consists in principle of two sub-devices 13.1, 13.2, wherein the first sub-device 13.1 is formed from three cleaning tubes 90.1 - 90.3, preferably made of stainless steel. The first sub-device 13.1 is used to clean the side walls I, II 15.1, 15.2 and the bottom wall 16 of an interior space 4. All three cleaning tubes 90.1 - 90.3 are equipped with bearing blocks 91.1 - 91.12, preferably with four bearing blocks 91.1 - 91.4, 91.5 - 91.8, 91.9 - 91.12 spaced at defined intervals per cleaning tube 90.1, 90.2, 90.3, and are thus fixed, but rotatably, to the frame 6, see Figure 1. Fig. 1a, fastened. The support blocks 91.1 - 91.8 are fastened to the two vertical tubes 20.5, 20.6 of the frame 6. One outer side of the tubes 20.5, 20.6 faces the side wall I, II 15.1, 15.2 of the interior 4 of the container 3. The support blocks 91.9 - 91.12 are fastened to the lower horizontal tube 20.2 of the frame 6, the outer side of which faces the lower side, the floor wall 16 of the interior 4. Distributed along the length of the pipes 20.2, 20.5, 20.6, twelve support blocks 91.1 - 91.12 are arranged at predetermined intervals, and four support blocks 91.1 - 91.4, 91.5 - 91.8, 91.9 - 91.12 are arranged for each cleaning pipe 90.1, 90.2, 90.3. The fastening points 39.1 - 39.3 for the support blocks 91.1 - 91.12 are thus located in the side area of ​​the frame 6, specifically on the outer sides of the two vertical pipes 20.5, 20.6 and on the lower side of the base frame 26, the outer side of the lower horizontal pipe 20.2. That is, the support blocks 91.1 - 91.12 are located on the side of the frame 6, on the outer sides of the two vertical pipes 20.5, 20.6 and on the lower side of the base frame 26, the outer side of the lower horizontal pipe 20.2.12 are located in the area of ​​the vertical plane 22 of the frame 6, see . Fig. 1, arranged, wherein the fastening point 39.1, 39.2 of the vertical tubes 20.5, 20.6 each comprises four fastening points on the tube 20.5, 20.6. The same applies to the fastening point 39.3 of the horizontal tube 20.2. For the sake of clarity, in the Fig. 1a the four fastening points for the four bearing blocks 91.1 - 91.4 of a cleaning pipe 90.1, 90.2, 90.3 are each marked with a reference numeral 39.1, 39.2, 39.3.

[0076] The two vertical cleaning tubes 90.1, 90.2 are arranged parallel to the side walls I, II 15.1, 15.2, and the horizontal cleaning tube 90.3 is arranged parallel to the bottom wall 16 of the interior 4 of a container 3. For cleaning the side walls I, II 15.1, 15.2 and the bottom wall 16, the three cleaning tubes 90.1, 90.2, 90.3 have a plurality of threaded holes at defined intervals on the front 92 and the back 93. Front 92 means facing the end wall 18. Back means opposite to the forward direction 25. A specific number of fan nozzles 94.1–94.3 are inserted into these threaded holes on the front 92 of the cleaning tubes 90.1, 90.2, 90.3. The threaded holes on the back 93 of the cleaning tubes 90.1, 90.2, 90.3 are connected via hoses 95.1, 95.2, 95.3 to a high-pressure cleaning system (not shown here). Furthermore, all three cleaning tubes 90.1, 90.2, 90.3 each equipped with a pneumatic or hydraulic motion cylinder 96.1 - 96.3, preferably with electric cylinders 96.1, 96.2, 96.3. The three electric cylinders 96.1, 96.2, 96.3 are mounted on the two vertical tubes 20.5, 20.6 and the lower horizontal tube 20.2 of the frame 6, see . Fig. 1a, attached. The electric cylinders 96.1, 96.2, 96.3 have the task of rotating the cleaning tubes 90.1, 90.2, 90.3, which are arranged to rotate about their longitudinal axis 166, and thus the fan nozzles 94.1 - 94.3. The rotation takes place within a predetermined angular range, from an initial / starting position, by plus / minus 45 degrees, so that the fan nozzles 94.1 - 94.3 can, strictly speaking, be pivoted by a total of 90 degrees. By pivoting the fan nozzles 94.1 - 94.3, the cleaning jet can be directed at different angles onto the surface to be cleaned, in particular the surface of the side wall 15.1, 15.2 and the surface of the bottom wall 16, see Fig. 7, hit.

[0077] The first embodiment I of the second partial device 13.2 relates to the cleaning of the ceiling 17 and end wall 18. The first embodiment I of the second partial device 13.2 has a cleaning tube 97, also made of stainless steel. This cleaning tube 97 is not attached to the upper horizontal tube 34 of the frame 6 via bearing blocks, but rather the entire partial device 13.2 is attached to the lower and upper horizontal tubes 20.2, 34 of the frame 6. The first embodiment I of the second part-device 13.2 consists of a lower drive shaft 99 and two upper deflection shafts 100.1, 100.2, a drive unit 101, preferably comprising a geared motor 101, four bearing brackets 102.1 - 102.4, comprising two upper bearing brackets 102.1, 102.2 arranged on the horizontal rectangular tube 34 of the frame 32 of the frame 6 and two lower bearing brackets 102.3, 102.3 arranged on the horizontal rectangular tube 20.2.4, two vertically extending conveyor belts 98.1, 98.2, preferably consisting of toothed belts 98.1, 98.2 and two fastening means, for attaching the horizontal cleaning tube 97 to the belts 98.1, 98.2, preferably to two toothed belts 98.1, 98.2. The front 92 of the cleaning tube 97 also has fan nozzles 104 at predetermined intervals and hoses 105 on the rear 93. The fan nozzles 104 can also be pivoted to direct the cleaning jet at different angles onto the surface to be cleaned, in order to optimally reach the surface of the ceiling wall 17. The fan nozzles 104 can assume different angles onto the surface to be cleaned due to the cleaning tube 97 being horizontally movable on the toothed belts 98.1, 98.2 via deflection shafts 100.1, 100.2.

[0078] The horizontal cleaning tube 97 is intended for cleaning the ceiling wall 17 and the end wall 18 of a container 3. The cleaning tube 97 is not rotated by an electric cylinder, but is attached to two vertical toothed belts 98.1, 98.2, with one toothed belt 98.1, 98.2 located next to the vertical tube 20.5, 20.6 and within the vertical surface 22 of the frame 6. The toothed belts 98.1, 98.2 are driven by the two lower drive shafts 99, which are equipped with toothed belt pulleys 106.1, 106.2. The drive shaft 99 is powered by a synchronized geared motor 101, which has a drive belt 107, the drive belt 107 being guided over two toothed belt pulleys 108.1, 108.2. One toothed belt pulley 108.1 is located on the geared motor output shaft and the other toothed belt pulley 108.2 on the input shaft 99. The geared motor 101 is mounted on a lower horizontal tube 20.2 welded mounting plates, screwed to mounting point 40.1, see . Fig. 1a.

[0079] Furthermore, the two vertical toothed belts 98.1, 98.2 are guided from the lower drive shaft 99 to the two upper deflection shafts 100.1, 100.2, which are equipped with toothed belt pulleys 110.1 - 110.4, in a guide channel 109.1, 109.2. The deflection shaft 100.1 is located on the outside of the upper horizontal tube 34, which faces the ceiling wall 17, while the deflection shaft 100.2 is located on the outside of the upper horizontal rectangular tube 34, which faces the end wall 18. The mounting points for the bearing brackets 102.1, 102.2 of the deflection shafts 100.1, 100.2 can be seen in the Fig. 1a can be taken from.

[0080] The second embodiment II of the partial device II 13.2 also relates to the cleaning of the ceiling 17 and end wall 18 and has the same upper cleaning tube 97.1 with the fan nozzles 104 and hose lines 105 arranged on it. This cleaning tube 97.1 is not attached to the upper horizontal tube 34 of the frame 6 via bearing brackets 102.1, 102.2, but the complete second embodiment II of the second partial device 13.2 is attached to the lower and upper horizontal tubes 20.2, 34 or to the two vertical rectangular tubes 20.5, 20.6 of the frame 6. The second embodiment II of the second partial device 13.2 is shown in the following for better illustration: Fig. 4 is shown as a dashed line and, for clarity, can also be shown in the Fig. 1b. The second embodiment II of the second partial device 13.2 now consists of two linear units 124.1, 124.2, each comprising a profile rail guide 125.1, 125.2 and a tool slide 126.1, 126.2. The tool slides 126.1, 126.2 are moved via a toothed belt drive (not shown). One linear unit 124.1 therefore has a drive system 127 and is connected to the other, parallel-spaced linear unit 124.2 via a shaft 99. Both linear units 124.1, 124.2 are arranged vertically on the support structure 37 of the frame 6. The horizontal cleaning tube 97 is rotatably attached to the two tool slides 126.1, 126.2 and, due to the linearly movable tool slides 126.1, 126.2, can be moved parallel to the end wall 18.To tilt the fan nozzles 14, the cleaning tube 97 is connected to an actuating drive 128, which can adjust the cleaning tube 97 about its longitudinal axis 167 within an angular range 165°, plus 90° and minus 90° from a basic position. The actuating drive 128 can consist of a motion cylinder, preferably an electric cylinder. Next, in the... Fig. 5 the drying unit 14 is considered.

[0081] From the Fig. Module 5, assembly V 10 with drying unit 14, is shown in perspective. The components from the Fig. 1, Fig. 2, Fig. Reference symbols 3 and 4 are adopted analogously here.

[0082] The drying unit 14 consists of four tubes 112.1 - 112.4, preferably made of stainless steel, with mounting brackets 115.1 - 115.4 attached to the tubes 112.1 - 112.4. The mounting brackets 115.1 - 115.4 arranged on the tubes 112.1 - 112.4 are used for mounting at the designated attachment points of the vertical 20.5, 20.6 and horizontal rectangular tubes 20.2, 34 of the support structure 37 of the frame 6, see [reference]. Fig. 1a, attached. The vertical 20.5, 20.6 and horizontal rectangular tubes 20.2, 34 are the same tubes of the support structure 37 to which the cleaning unit 13 is attached. Furthermore, the drying unit 14 has a radial blower 117, which is connected to the tubes 112.1 - 112.4 via air ducts (not shown). Connections 116.1 - 116.4 for the air ducts are provided on the tubes 112.1 - 112.4 for this purpose. The four tubes 112.1 - 112.4, designed as drying nozzles 113.1 - 113.4, therefore have a straight air slot 114.1 - 114.4 along their entire length. Other arrangements and configurations of the air slots 114.1 - 114.4 on the pipes 112.1 - 112.4 of the drying nozzles 113.1 - 113.4 are conceivable. The air slots 114.1 - 114.4 of the drying nozzles 113.1 - 113.4 point at approximately a 90-degree angle to the surface to be dried, here the bottom wall 16, the ceiling wall 17 and the two side walls I, II 15.1, 15.2 of the interior 4 of a container 3, see . Fig. 7.

[0083] The radial blower 117 is mounted on a bracket 119 with its base 118. The bracket 119 serves both as a support for the blower 117 and as a connector to the frame 6. The bracket 119 is designed so that it can also be screwed onto the horizontal tubes 20.7, 20.8 of the base frame 26 at designated mounting points.

[0084] All four drying nozzles 113.1 - 113.4 are equipped with mounting brackets 115.1 - 115.4, preferably with three mounting brackets 115.1 - 115.4 spaced precisely apart from each other, so that a total of twelve mounting brackets are provided on the four tubes 112.1 - 112.4, which are used to attach the drying unit 14 to the frame 6. The drying nozzles 113.1 - 113.4 are thus attached to the frame 6 via the mounting brackets 115.1 - 115.4. The mounting brackets 115.1 - 115.2 of the two vertical drying nozzles 113.1, 113.2 are attached to the two vertical tubes 20.5, 20.6 of the frame 6, respectively. on the outside of the pipes 20.5, 20.6, which faces away from the end wall 18 of the interior 4 of a container 3, i.e. on the back 63 of the vertical plane 22 of the frame 6, or viewed in the direction of reverse travel 25, see Fig. 1a. The mounting brackets 115.3, 115.4 of the horizontal drying nozzles 113.3, 113.4 are attached to the top 87 of the upper horizontal tube 34 and to the bottom 88 of the lower horizontal tube 20.2 of the frame 6, respectively, to the outer sides of the horizontal tubes 20.2, 34, see Fig. 1a, wherein the upper outer side of pipe 34 faces the ceiling wall 17 and the lower outer side of pipe 20.2 faces the floor wall 16. The mounting brackets 115.3 for the lower horizontal drying nozzle 113.3 are therefore arranged on the lower side of the base frame 26. The connection points of the twelve mounting brackets 115.1–115.4 on the frame 6 are designed such that the module of assembly V 10 of the drying unit 14, independently of the module of assembly IV 9 of the cleaning unit 13, can also be arranged on the two identical vertical pipes 20.5 and 20.5 and the two identical horizontal pipes 20.2 and 34. The two assemblies IV, V 9, and V 10 can be replaced or repaired independently of each other.

[0085] For the sake of clarity, the following were included in the Fig. 1a for the twelve fastening points of the twelve fastening brackets from the Fig. Only four reference numerals were used. For every three mounting brackets per drying nozzle 113.1 - 113.4, a reference numeral 115.1 - 115.4 was assigned. The same applies to the attachment of the twelve mounting brackets to the frame 6. For every three mounting points per drying nozzle 113.1 - 113.4, a reference numeral 43.1 - 43.4 was used on the frame 6. That is, the reference numeral for three mounting brackets on a drying nozzle 113.1 is 115.1, and for three mounting points of a drying nozzle 113.1 on the frame 6 is 43.1, etc. Next, in the Fig. 6 the cleaning system 1, completed with the modules of the five assemblies I - V 6.1, 7, 8, 9, 10, are shown.

[0086] The Fig. Figure 6 shows a schematic representation of the cleaning system 1 according to the invention, preferably in an oblique view from the side and from the front.

[0087] Cleaning system 1 consists of five modules, which, when completed as five individual subassemblies I-V 6.1, 7, 8, 9, 10, comprise cleaning system 1. The basis of cleaning system 1 is the first subassembly I 6.1, the frame 6. The frame 6 consists of a base frame 26 and a support structure 37 arranged perpendicular to it. The support structure 37 is reinforced here with a diagonal cross 162. The base frame 26 forms a right-angled module with the support structure 37, whereby the base frame 26 and the support structure 37 are connected for reinforcement by two diagonal supports 23.1, 23.2. The diagonal supports 23.1, 23.2, in turn, can support containers, such as a disinfection container 164. The frame 6 itself supports the individual subassemblies II-V 7, 8, 9, 10.

[0088] The second assembly, II 7, the traversing unit 11, with its two drive units 46.1 and 46.2, is integrated into the underside of the base frame 26. For clarity, only one drive unit, 46.2, is shown. The drive for the drive units 46.1 and 46.2 consists of a geared motor 52, which is located centrally at the rear end 24 of the frame 6, on the transverse horizontal tube 20.4 of the base frame 26. The third assembly, III 8, consisting of the guide and centering unit 12, is mounted on the right and left sides of the base frame 26 of the frame 6 with the two toothed belt drives 65.1 and 65.2, of which only one toothed belt drive, 65.2, is shown. The toothed belt drives 65.1, 65.2 are laterally connected to the frame 6 via four flange bearing pairs 66.1 - 66.4, of which only three flange bearing pairs 66.2, 66.3, 66.4 are shown. The adjustment of the toothed belt drives 65.1, 65.2 is achieved via the linear guide 71 arranged centrally in the base frame 26, which is shown in more detail in the . Fig. 3 is shown and described. The lifting device 81, which is arranged below the base frame 26, cannot be shown here for the sake of clarity, but is explained in the Fig. 3 is evident. Next, the frame 6 is completed with the module of the fourth assembly IV 9, the cleaning unit 13. For this purpose, cleaning tubes 90.1, 90.2, 90.3, rotatable about their longitudinal axis 166, 167, are provided with bearing blocks 91.1 - 91.12 (shown in Fig. 4) and fan nozzles 94.1, 94.2, 94.3 are fixedly arranged on the support structure 37 of the frame 6. The upper horizontal cleaning tube 97, on the other hand, is attached to two toothed belts 98.1, 98.2 and also has fan nozzles 104. The cleaning tube 97 has a drive 101, see Fig. 4, and can thus be positioned along the vertical plane 22, parallel to the end wall 18 of the interior 4 of a container 3, see Fig. 7, proceed. The horizontal cleaning tube 97 of the partial device II 13.2 has 93 connections for hose lines on the rear side (see. Fig. 4) and at certain intervals on the front 92 fan nozzles 104, wherein the fan nozzles 104 in the starting position 122 of the cleaning process point perpendicular to the ceiling wall 17 of the interior 4 of a container 3.3 and along the forward direction 25 when reaching the end wall 18 (see Fig. 7a) from the starting position 122, swivel 90 degrees to the front wall 19 and then drive vertically downwards along the front wall 18 to the end position 123.

[0089] The drive 101 for the cleaning tube 97 is arranged on the front transverse horizontal rectangular tube 20.2 of the base frame 26. The cleaning tubes 90.1, 90.2, 90.3, 97 are connected via hose lines 95.1 - 95.3, 105, see Fig. 4, connected to a container for the cleaning fluid. The supply of cleaning fluid to the cleaning unit 13 from a container located on the frame 6 is not shown here for clarity.

[0090] To enable drying of the cleaned surfaces of the interior 4, the two side walls I, II 15.1, 15.2, the floor wall 16, the ceiling wall 17 and the end wall 18, the first assembly I 6.1 must be completed with the module of the fifth assembly V 10 of a drying unit 14. For this purpose, four pipes 112.1 - 112.4 are required as drying nozzles 113.1 - 113.4, which are connected with mounting brackets 115.1 - 115.4 and air slots 114.1, 114.4 (shown in Fig. 5) are rigidly arranged on the support structure 37 of the frame 6. The drying nozzles 113.1 - 113.4 are supplied with an airflow from the blower 117 via air ducts (not shown), see Fig. 3, supplied. In the Fig. Figure 6 does not show the additional drying unit 14 of assembly V 10. The advantageous embodiment of a cleaning system 1 is shown, in which the cleaning tubes 90.1, 90.2, 90.3, 97 are also used for drying the interior 4.

[0091] The use of such a cleaning system 1 can be described below. Fig. 7a u. Fig. 7b can be taken from there.

[0092] In the Fig. Figure 7a shows a schematic representation of several variants for loading a cleaning system 1 and various embodiments of cleaning systems 1. Loading can take place in a vehicle 2, preferably a truck with a body and / or a refrigerated container 3 as a semi-trailer, wherein the truck body can also consist of a refrigerated container 3.

[0093] In the first variant I of the loading process, the cleaning system 1, which has a transport device 129 under the frame 6, is transported using a lifting vehicle 140, preferably a forklift, and placed on the loading platform 141 of a vehicle 2 for cleaning the interior 4. This is the starting and ending position 158 of the cleaning system 1. From here, the cleaning processes proceed as described previously. The cleaning process begins with the centering of the cleaning system 1, followed by the cleaning operation. For this purpose, the cleaning system 1 moves forward 25 along the bottom wall 16 to the end wall 18 and back, see vehicle 2 and container 3.3.

[0094] In the next loading variant II, interior door cleaning, as shown for container 3.4, is included. Therefore, the cleaning system 1 is located on a loading and unloading platform 143. The loading and unloading platform 143 has a transport device 129 for a lifting vehicle 140. The lifting vehicle 140 can thus transport the cleaning system 1, which is positioned on the loading and unloading platform 143. The lifting vehicle 140 moves the cleaning system 1 to the two open doors 144.1 and 144.2 and positions the cleaning system 1 at a height of 139 on the loading area 141 and between the open doors 144.1 and 144.2. The gap between the loading and unloading platform 143 and the loading area 141 is bridged by means of two ramps 145.1, 145.2, as shown for container 3.4. The cleaning system is located in the end and start position 158. From this position 158, the cleaning system 1 can now move independently from the loading and unloading platform 143 to the loading area 141.The unloading platform 143 is driven onto the loading area 141, at which point the cleaning process begins. During this drive, the cleaning system 1 already cleans the inner door surfaces 146.1, 146.2, etc., using the partial device I 13.1 of the cleaning unit 13, which is designed for the side walls 15.1, 15.2 of the interior 4 of a container 3. Before the cleaning process, the door leaves 144.1, 144.2 are attached to the loading and unloading platform 143 by means of clamps (not shown), preferably by means of gate stays that allow for easy locking and unlocking of the door leaves 144.1, 144.2. Securing the door leaves 144.1, 144.2 is necessary to maintain their open positions during the cleaning process. Once the cleaning system 1 has arrived in the interior 4 of container 3.4, the process cleaning begins with the centering of the cleaning system 1, followed by the cleaning process in container 3.4 as described above.

[0095] With another embodiment of a cleaning system 1, interior door cleaning can be carried out, as shown for container 3. The cleaning system 1 is positioned on a loading and unloading platform 143 and moved between the open doors 144.1, 144.2 by a lifting vehicle 140. The lifting vehicle 140 adjusts the height 139 of the cleaning system 1 relative to the loading area edge 142. The cleaning system 1 is now in the end and start position 158. The cleaning process is now not carried out by moving the cleaning system 1 forward in the direction 25, but by a cleaning unit 169, which is arranged on both sides of the cleaning system 1. These two cleaning units 169 are technically identical to the cleaning unit 13, which is used for cleaning the end wall 18, see [reference]. Fig. 1b u. Fig. 4. The cleaning unit 169 has a nozzle bar 170.1, 170.2, which is connected to two belts or two linear units, as shown in the Fig. 1b u. Fig. 4 is known to be horizontally mounted. The nozzle bar 170.1, 170.2 moves vertically from top to bottom. This cleaning unit 169 is located on both sides of the frame 6. The drive unit (not shown) for the cleaning unit 169 is located in the center of the frame 6 and moves both nozzle bars 170.1, 170.2 synchronously.

[0096] Another loading variant is based on the previously described loading method. In this method, the cleaning system 1 is lowered by a lifting vehicle 140 onto a stationary scissor lift 148 with an integrated loading and unloading platform 143, whereby both embodiments of cleaning systems 1 can be used here. Scissor lifts 148 can be used where parking bays for containers 3.1 are provided.

[0097] A container 3.1 is then parked backwards in front of a scissor lift 148. The scissor lift 148 automatically adjusts the height 139 of the cleaning system 1 to the loading area edge 142. The cleaning system 1 is now in the end and start position 158. The cleaning process can begin with the cleaning of the inner door surfaces 146.1, 146.2, as previously described during loading.

[0098] Another alternative loading method for a cleaning system 1 can be carried out from a fixed ramp 147. A vehicle 2 or container 3.2 is parked in reverse in front of ramp 147. From ramp 171, the cleaning system 1 can then drive itself, for example, into the interior 4 of container 3.2.

[0099] Fig.Figure 7b shows a loading configuration of the cleaning system 1, in which the scissor lift 148 is not stationary but mounted on a mobile base 149. This allows the cleaning system 1 to be used at any location within a parked vehicle 2 or container 3. The mobile base 149 is designed to provide, in addition to the cleaning system 1, which stands on a loading and unloading platform 143 and a scissor lift 148, a water supply 150 and a power supply 151. This mobile base 149 can be designed as a trailer, making the cleaning system 1 mobile and usable at any location. The cleaning system 1 is connected to a liquid tank 150 via a liquid supply line 152 and to an electrical power source 151 via an electrical cable 153.

[0100] The cleaning system 1 can begin once it is positioned in front of the open doors 144.1, 144.2, at height 139 of the loading area edge 142, and at a specific lateral distance 154.1, 154.2 from the open doors 144.1, 144.2. The positioning of the mobile base 149 for the scissor lift 148 is determined by several sensors 155 located on the loading and unloading platform 143. These sensors 155 ensure the optimal position of the mobile base 149 for moving the cleaning system 1 between the doors 144.1, 144.2. The doors 144.1, 144.2 are secured to locking devices 156 located on the loading and unloading platform 143.

[0101] Cleaning system 1 starts its cleaning process from the end and start position 158 on the loading and unloading platform 143. Once the cleaning process is complete and cleaning system 1 is back in the end and start position 158 on the loading and unloading platform 143, all supply systems 159 are decoupled.
