Description

Method for cleaning a cargo space of a means of transport Description

[0001] The present application relates to a method for cleaning a loading space of a means of transport according to claim 1.

[0002] The method utilizes a cleaning robot that performs at least one cleaning process automatically or independently. During this cleaning process, the cargo space of the means of transport is cleaned by the cleaning robot. "Independently" or "automatically" in the context of the present application means that the cleaning of the cargo space as such takes place without the involvement of a user. For example, it is conceivable for a user to manually select a cleaning program according to which the cargo space is to be cleaned. This cleaning program defines operating parameters for the cleaning robot for performing at least one cleaning process, for example a temperature of the cleaning fluid, a quantity of fluid to be dispensed, and / or a concentration of a cleaning agent in the cleaning fluid.The cleaning robot can then clean the cargo area without any further user intervention and thus operates independently or automatically within the meaning of the present application. At least one operating parameter can also be changed (possibly multiple times) during a cleaning process.

[0003] The means of transport can in particular be a truck or a semi-trailer for a truck. The loading space is typically spatially delimited by walls, in particular a loading space floor, a loading space deck, side walls and an end wall, wherein the loading space floor, the loading space ceiling and the walls together preferably have the shape of a cuboid. One of the walls, typically opposite the end wall, is designed to be openable, for example by means of pivoting doors, so that cargo, for example in the form of solid objects, can be brought into and removed from the loading space. For the purpose of transport, the openable wall is typically closed and the respective load is secured in the loading space.

[0004] The cleaning of the cargo space may comprise one or more cleaning operations. A cleaning operation may, in particular, involve a movement of the cleaning robot first forward in a main direction of the cleaning robot along an entire length of the cargo space and then back against the main direction. along the entire length of the cargo space. Depending on the level of soiling in the cargo space, several cleaning operations may be required to achieve the desired level of cleanliness. State of the art

[0005] A method of the type described above is already known in the prior art. Reference is made to published patent application DE 102019 004959 A1. This discloses a cleaning robot suitable for cleaning the cargo space of a means of transport. To carry out a cleaning process, the cleaning robot is moved into the cargo space of the means of transport, whereupon the cleaning robot can be moved within the cargo space by means of its own drive. The surfaces of the walls of the means of transport are typically cleaned by applying a cleaning fluid sprayed via cleaning nozzles. As the cleaning robot moves along a longitudinal axis of the cargo space, all points on the walls of the means of transport are thus exposed to the cleaning fluid, so that the entire cargo space is cleaned.After cleaning is completed, the cleaning robot is removed from the cargo area.

[0006] The cleaning of the cargo area of ​​a means of transport requires documentation for many applications. Therefore, the operator of a particular means of transport is generally required to provide evidence of successful cleaning. Such proof may be required, for example, to a regulatory authority, such as a government agency, or to a client using the services of the operator of the means of transport. Especially for operators with a large fleet of transport vehicles, the effort required to manage and document the cleaning of the various means of transport can be considerable.

[0007] In this regard, reference is made, for example, to document WO 2013 / 048252 A2. This describes a method for process assurance of a tank cleaning process of a transport tank, wherein the transport tank is cleaned using a cleaning fluid, the method comprising the following steps: storing a transport tank identifier in a digital memory, storing a start time of the cleaning process in a digital memory, performing a first series of measurements of a cleaning fluid parameter during the cleaning process upstream of the point at which the cleaning fluid contacts the interior of the transport tank, storing an end time of the cleaning process in a digital memory, Transmitting the series of measured cleaning fluid parameters, the start time, the end time and the transport tank identification to a data storage device remote from the tank cleaning system and performing a statistical analysis of the series of measured cleaning fluid parameters. Task

[0008] The present application is therefore based on the object of providing a method that simplifies the documentation of the cleaning of a respective cargo space. Solution

[0009] The underlying problem is solved according to the invention by means of a method having the features of claim 1. Advantageous embodiments emerge from the associated subclaims.

[0010] According to the method according to the invention, information relating to at least one identification feature of the means of transport to be cleaned is first recorded by means of at least one sensor. Such an identification feature can in particular be a vehicle license plate number, which is optically recorded, for example, by means of a sensor formed by a camera. It is also conceivable, for example, for the identification feature to be formed by a barcode or QR code, which are equally optically detectable. Furthermore, identification can take place by means of wireless communication, for example by means of an RFID chip on the means of transport and a sensor suitable for reading the RFID chip. Other variants for recording information about at least one identification feature by means of at least one sensor are also conceivable.

[0011] The acquired information is then sent to a data processing device. This device can be located locally in the vicinity of the sensor and communicate with the sensor, for example, via a wired or wireless connection. It is also conceivable for the data processing device to be accessible via the internet, with the sensor, for example, interacting with a transmitting / receiving unit that can transmit the acquired information to the data processing device.

[0012] The data processing device compares the recorded information with information previously stored in a database, whereby the previously stored information relates to the same means of transport. The means of transport is identified using this information. Thus, it is conceivable, for example, that in an initial registration step for a specific means of transport, a license plate number or other identification feature is registered, which is then logically linked to the means of transport in the database. When the same identification feature, such as the license plate number, is subsequently recorded, it can be determined, by comparing it with the data recorded during the registration step, that the means of transport due for cleaning is the one linked to the identification feature (e.g., license plate number).

[0013] Once the cargo hold of the affected means of transport has been cleaned, a cleaning certificate is automatically generated, documenting the completion of the cleaning process. This cleaning certificate is then stored in a database with a reference to the means of transport. This database can, for example, be the same database in which the information about the means of transport is stored.

[0014] The success of the method depends on the identification of the respective means of transport, but not on the sequence in which the cleaning of the respective cargo space and the identification of the means of transport are carried out. It is therefore conceivable that the cargo space is first cleaned automatically by the cleaning robot and that the means of transport is identified before, during, or after cleaning. The only essential factor for the success of the invention is that the means of transport is identified so that the cleaning certificate, which is automatically generated after cleaning is completed, can be assigned to the means of transport and stored in the database with a reference to it. It is also conceivable that the cleaning certificate is printed out.

[0015] The method according to the invention has many advantages. In particular, it is possible to automate the creation and storage of a cleaning certificate, which serves as proof of the successful cleaning of a particular cargo hold, and to store it in such a way that it can be retrieved from the database at any time if necessary. This significantly simplifies the documentation and management of completed and completed cleaning processes for a means of transport, especially for a large number of means of transport, compared to the state of the art.

[0016] In a particularly preferred manner, it is provided that the created Cleaning certificate is automatically assigned to a user account, which also has the This means of transport. For example, an operator of a fleet of Means of transport have a user account in which all of the fleet's transport vehicles are stored. By identifying at least one identification feature, the method first determines which of the fleet's transport vehicles is required for the respective cleaning, so that after cleaning has been completed, the corresponding cleaning certificate is saved to the user account and preferably to the transport vehicle in question. For administration, it is now only necessary to log in to the user account, after which the cleaning certificates for the individual transport vehicles can be viewed particularly easily and retrieved when required. It is also conceivable to provide one or more access points for third parties to the respective user account, who could, for example, be granted restricted access to the user account.In this way, third parties can independently view one or more cleaning certificates if necessary.

[0017] Particularly preferably, the at least one sensor by which the at least one identification feature of the means of transport is detected is formed by an optical sensor, for example a camera. Such a sensor makes it possible to detect optical information, in particular in the form of individual images or moving images. Such a sensor is particularly well suited to detecting a multitude of different identification features, so that the means of transport can be identified by evaluating the detected information.

[0018] As already explained above, it is also particularly advantageous if at least one identification feature of the respective means of transport is formed by a vehicle registration number. Vehicle registration numbers are comparatively easy to detect optically and are typically located in a specific, always identical spatial area of ​​the means of transport in relation to the respective means of transport, so that the sensor provided for identifying the vehicle registration number can be specifically aimed at this area. Nevertheless, examples are readily conceivable in which a means of transport does not have a vehicle registration number. This could be the case, for example, with a sea container. Such a container would therefore be identified using another identification feature, for example an RFID chip, a QR code and / or a barcode.

[0019] In a particularly advantageous embodiment of the method according to the invention, information stored in the database relating to the identified means of transport is retrieved. Depending on the retrieved information, at least one operating parameter of the cleaning robot for carrying out at least one cleaning process and / or a type of cleaning process can then be automatically determined. be set. To carry out this method, it is important that the means of transport is identified at least before the last cleaning process of the respective cleaning operation, so that the automatic setting of at least one operating parameter of the cleaning robot can be carried out and is effective for this cleaning process. The means of transport is preferably identified before cleaning of the loading space begins. Information stored in the database for the respective means of transport can include, for example, the type of load last transported, on the basis of which the requirements for the upcoming cleaning can be determined. For example, it is conceivable that food was transported in the loading space of the means of transport, which, in contrast to, for example, the transport of furniture, requires a different type of cleaning.Using this information about the means of transport stored in the database, the cleaning robot can be automatically configured, i.e. its operating parameters can be automatically adjusted, so that it can clean the cargo space in a targeted manner. For example, it is conceivable that the cleaning fluid to be dispensed by the cleaning robot is mixed with a comparatively high concentration of a cleaning agent in order to generate a comparatively high cleaning performance. Increasing the dispensed quantity of cleaning fluid or setting a specific temperature for the cleaning fluid and the like is also conceivable. The operating parameters can be adjusted in particular by means of a control unit of the cleaning robot and / or by means of a data processing device. This is also evident from the exemplary embodiment below.

[0020] Furthermore, such a method can be particularly advantageous in which information relating to the soiling level of the cargo space is acquired by means of at least one sensor. This can be particularly advantageous before the start of a cleaning process. This information is sent to the data processing device and processed by the same, wherein at least one operating parameter of the cleaning robot for at least one cleaning process is preferably automatically adjusted depending on the processed information. The sensor can in particular be formed by an optical sensor, wherein preferably the same sensor is used for acquiring the soiling level of the cargo space as is also used for acquiring the information relating to the at least one identification feature of the means of transport.By means of the automatic adjustment of at least one operating parameter depending on a detected state of contamination, the cleaning of the loading space can be carried out in a particularly needs-based manner, with the consumption of cleaning agent and cleaning fluid in particular only being limited to this level. dimensions are taken as is actually necessary for successful cleaning of the cargo area.

[0021] In particular, it is conceivable that, upon detection of localized contamination, for example, on a wall of the means of transport, an increased application rate of the cleaning fluid is only temporarily set during a cleaning process, while the rest of the cleaning process is carried out with a reduced application rate that is sufficient for cleaning the walls. Accordingly, it can be particularly advantageous if, during a cleaning process, at least one operating parameter is automatically changed at least once, preferably several times, depending on the processed information regarding the contamination level of the cargo space.

[0022] It can also be particularly advantageous if the level of soiling in the cargo space is recorded after a cleaning process has been completed. This makes it possible to check whether the desired cleaning result has been achieved, i.e. whether the cleaning carried out meets specified requirements. If this is not the case, another cleaning process can be carried out. If the cleaning has been successful, this can be taken into account when creating the cleaning certificate. It can therefore be advantageous to create the cleaning certificate in such a way that it documents the determined cleaning success. As a sensor suitable for recording the level of soiling, at least one camera and / or at least one lidar can be used.

[0023] It is also conceivable that information relating to a desired cleaning result for the means of transport to be cleaned is stored in the database. For example, it is conceivable that a particular means of transport should be cleaned particularly intensively because it was previously used to transport live animals. It can therefore be defined for the means of transport that cleaning is only considered successful if certain requirements are met. If sensors determine that the loading space no longer contains any soiling that would prevent the cleaning from being assessed as successful when the requirements are taken into account, the cleaning success is determined automatically. Preferably, the data relating to the requirements or the desired cleaning result can be assigned to the means of transport to be cleaned as a result of the identification of the means of transport.Cargo space can be retrieved from the database.

[0024] Furthermore, it can be particularly advantageous if information regarding the dimensions of the cargo space is acquired using at least one sensor. This information can be processed to control the cleaning robot to carry out the cleaning. This can, in particular, relate to controlling a chassis and / or setting operating parameters of the cleaning robot. The design of at least one sensor in the form of a lidar is particularly advantageous. Using such a sensor, the dimensions of the cargo space can be acquired particularly easily.

[0025] In a particularly advantageous embodiment, at least one operating parameter of the cleaning robot, which can be automatically adjusted, is formed by one of the following: Alignment of at least one cleaning nozzle; Application pressure of a cleaning fluid at at least one cleaning nozzle; Application rate of the cleaning fluid at at least one cleaning nozzle; Activation state of at least one cleaning nozzle; Distance of at least one cleaning nozzle from a wall of the loading space; Temperature of the cleaning fluid; Movement speed of the cleaning robot; Concentration of a cleaning agent in the cleaning liquid; Distance of the cleaning robot from a wall of the loading area.

[0026] These operating parameters are particularly well-suited for adjusting the cleaning performance of the robot cleaner to meet specific needs. However, additional operating parameters are also conceivable.

[0027] In a further advantageous embodiment of the method according to the invention, information relating to obstacles located in the cargo space is detected by means of at least one sensor before the start of a cleaning process. The sensor used for this purpose can again preferably be an optical sensor, for example a camera, or a lidar. For example, the sensor can be the same sensor by means of which information relating to the at least one identification feature is detected. The information relating to obstacles located in the cargo space is then sent to the data processing device and processed by it. In this way, an obstacle can be detected, wherein in the If such an obstacle, for example a piece of wood, is detected, the cleaning robot is automatically controlled in such a way that the cleaning process cannot begin until the obstacle is removed or - if a cleaning process has already started - the cleaning process is interrupted. This procedure significantly increases the operational reliability of the cleaning robot, in particular reducing damage to the cleaning robot as a result of a collision with an obstacle. It is also conceivable that, beyond the risk of damage to the cleaning robot, a particular cleaning process is negatively influenced so that - possibly unnoticed - cleaning is not carried out optimally even though it appears to have been completed without problems. The identification of obstacles and their removal is therefore particularly advantageous.

[0028] In a further development of the method, at least one cleaning process comprises a drying step during which the cargo space is dried. In particular, to carry out the drying step, air, for example heated air, can be applied to the surfaces of the walls of the means of transport, in particular to the cargo space floor. This can be done in particular by means of a fan, wherein, for example, the cleaning nozzles that are also provided for applying the cleaning fluid are used to apply the air. Drying the cargo space at the end of cleaning it is particularly advantageous in order to immediately prepare the cargo space for further use. The removal of moisture also prevents the renewed formation of germs and the like.

[0029] Furthermore, a particularly advantageous embodiment of the method is one in which the cleaning fluid used to carry out at least one cleaning process is at least partially collected and at least partially treated after being discharged into the cargo space. The cleaning fluid treated in this way can then be used at least in part to carry out a further cleaning process. Depending on the type of cleaning, it may also be necessary to treat the collected cleaning fluid before it can be released into a public sewer system. The efficiency of the overall operation of a respective cleaning robot or an associated cleaning station can be particularly enhanced with this method step, since the use of new cleaning agent can be significantly reduced.This makes the process for cleaning the cargo space particularly advantageous from an ecological point of view.

[0030] In a further advantageous embodiment of the method according to the invention, if a booking for cleaning is made for the cargo space of a respective Means of transport, telemetry data of the means of transport, in particular location data, are recorded and processed. A time window for carrying out the cleaning is then automatically reserved depending on the processed telemetry data. This means that the respective cleaning station, which includes the cleaning robot, is kept available for the respective means of transport in the reserved time window. Use by third parties is hereby temporarily prevented during the reserved time window. Particularly preferably, the time window can be changed depending on the recorded telemetry data, for example if a change in the predicted arrival time of the means of transport in question at the respective cleaning station is foreseeable. This can occur, for example, in the event of traffic disruptions. The identification of the respective means of transport using at least one identification feature then enables the cleaning station orof the cleaning robot to carry out the cleaning of the respective cargo space. This allows the reservation and activation of the cleaning robot for cleaning to be organized and processed automatically. This is particularly advantageous for the operator of the means of transport, as manual administration and organization are eliminated. Examples of implementation

[0031] The invention is explained in more detail below using an exemplary embodiment illustrated in the figures. It shows: Fig. 1 : A vertical longitudinal section through a set comprising a Cleaning station and a means of transport, Fig. 2: A horizontal longitudinal section through the set according to Figure 1, Fig. 3: A perspective view of a cleaning station, Fig. 4: A front view of the cleaning station according to Figure 3, Fig. 5: A vertical longitudinal section through the cleaning station according to Figure 3, Fig. 6: A perspective view of a cleaning robot, Fig. 7: A front view of the cleaning robot according to Figure 6, Fig. 8: A side view of the cleaning robot according to Figure 6.

[0032] An embodiment shown in Figures 1 to 8 comprises a cleaning station 1, which comprises a cleaning robot 5 for cleaning a loading space 3 of a means of transport 2. In the example shown, the means of transport 2 is formed by a semi-trailer, the loading space 3 of which is to be cleaned. For this purpose, the The transport means 2 is positioned relative to the cleaning station 1 such that the cleaning robot 5 can enter the loading space 3 of the transport means 2. The cleaning robot 5 is designed and configured to clean the loading space 3 independently or automatically, i.e., in particular, without the intervention of a user of the cleaning station 1.

[0033] The cleaning station 1, which is particularly clear from Figures 1 to 5, comprises a support frame 4, which forms a platform 7 at an end facing away from a base 13. The platform 7 is thus spaced from the base 13, wherein the platform 7 forms a flat driving plane that is oriented at least substantially parallel to a surface of the base 13. The arrangement of the platform 7 in the manner described enables the cleaning robot 5, which is mounted on the platform 7, to step from the platform 7 into the loading space 3 of the means of transport 2 without overcoming a height difference, wherein the platform 7 and a loading space floor 39 of the means of transport 2 are at least at a similar, preferably at the same, height level.

[0034] The cleaning station 1 further comprises a garage 8 in which the cleaning robot 5 can be stored in a parked position when not in use. The garage 8 comprises a plurality of side walls 16, a floor 14, and a roof 15, these elements together spatially enclosing an interior space 17 of the garage 8. Towards a front side of the garage 8, the interior space 17 is also delimited by a side wall 16 formed by an openable space-delimiting element 18. The space-delimiting element 18 can be selectively moved between an open position and a closed position. In the example shown, the space-delimiting element 18 is formed by a roller shutter-like roller door which, when the space-delimiting element 18 is in its open position, is stored rolled up in a storage box 47. When in its closed position, the space-delimiting element 18 secures the interior space of the garage 8 against unauthorized access.In the example shown, the floor 14 of the garage 8 is formed by the platform 7, so that the floor 14 of the garage 8 continues to an outer area 42 of the platform 7 without forming a height difference. This allows the cleaning robot 5 to move out of the garage 8 without having to climb or descend a step, ramp, or the like.

[0035] The support frame 4 of the cleaning station 1 has a plurality of stand elements 11, by means of which the cleaning station 1 is placed and stored on the base 13 in a support plane 12. As explained above, the platform 7 oriented parallel to the support plane 12. As a result of the provision of the distance between the support plane 12 and the platform 7, an intermediate space 43 is created between the platform 7 and the support plane 12, in which space, among other things, a liquid supply 9 is arranged in the example shown. This comprises a plurality of liquid tanks 19, 20, 21 and at least one pump 22. A first liquid tank 19 is formed by a water tank and, in the example shown, serves to store fresh water. The first liquid tank 19 can, for example, be equipped with a supply connection (not shown), by means of which the liquid tank 19 can be connected to an external supply line so that it can be filled with fresh water, for example from a municipal water supply. Furthermore, the liquid supply 9 has a second liquid tank 20, which here is formed by a cleaning liquid tank.As such, the second liquid tank 20 serves to hold a cleaning liquid intended for discharge into the cargo space 3 by the cleaning robot 5. The third liquid tank 21 serves as a cleaning agent tank for holding the cleaning agent, which is typically formed from a specific chemical formulation. The cleaning liquid held in the second liquid tank 20 is typically formed from a mixture comprising recaptured cleaning liquid, which was previously discharged by the cleaning robot 5 and then collected again by the collecting device 49, as well as, if necessary, fresh cleaning agent. The cleaning robot 5 is supplied with the cleaning liquid from the second liquid tank 20, which is fluidly connected to the cleaning robot 5 by a liquid line 23.The pump 22 cooperates with this liquid line 23 so that it is suitable for pumping the cleaning liquid stored in the liquid tank 20 through the liquid line 23 to the cleaning robot 5, at which the cleaning liquid is finally sprayed.

[0036] The cleaning station 1 further comprises a collecting device 49, which in the example shown comprises several individual collecting containers 10, which serve to collect and recirculate cleaning fluid discharged during a cleaning process of the transport means 2. For this purpose, the individual collecting containers 10 are each arranged at a height below an upper travel level of the platform 7. Furthermore, the travel level of the platform 7, on which the cleaning robot 5 can travel, is formed by a grating, so that discharged cleaning fluid can flow downward through the grating and thus be fed to the collecting device 49.

[0037] The cleaning station 1 can further comprise a treatment device 56 to which the collected cleaning fluid can be fed, in particular by means of a pump. The treatment device 56 can treat the cleaning fluid in such a way that it is at least partially suitable for carrying out a further cleaning process. The treatment can, in particular, comprise filtering the cleaning fluid of solids using one or more filters. The portion of the treated cleaning fluid suitable for further use is then fed to the second fluid tank 20. As explained above, cleaning agent can also be fed to this fluid tank 20.

[0038] The cleaning station 1 further comprises a power supply (not shown in the figures), by means of which the cleaning station 1 in general and the cleaning robot 5 in particular can be supplied with electrical energy. This supply can be provided indirectly and / or directly, with the intermediate storage of a certain amount of electrical energy, for example, by means of a battery, being particularly conceivable. The power supply comprises a supply connection (also not shown), to which an external supply line can be connected.

[0039] The cleaning station 1 also comprises a control unit 6, which here is fixedly arranged on a side wall 16 of the garage 8. The control unit 6 is designed and intended to control the cleaning station 1 in general and the cleaning robot 5 in particular. For this purpose, the control unit 6 is connected to the cleaning robot 5 by means of at least one data connection in a data-transmitting manner. This connection can be wired or wireless. In the example shown, the cleaning robot 5 is connected to the rest of the cleaning station 1 in addition to the liquid line 23 by means of a further supply line (not shown in the figures). This supply line can be used to supply the cleaning robot 5 with electrical energy provided by the power supply and also to exchange data with the control unit 6.

[0040] In the example shown, the control unit 6 comprises a data processing device suitable for electronically processing the information provided. This can, in particular, be information acquired by means of various sensors, which are explained separately below. The processing of this information is used in the example shown, among other things, to control the cleaning robot 5 by means of the control unit 6. to be controlled as needed and in this way to influence a cleaning process of the loading space 3 of the means of transport 2.

[0041] In the example shown, an input device 44 and a display device 45 are installed together with the control unit 6 in the combined form of a touch display. In this way, a user of the cleaning station 1 can make inputs that relate to at least one cleaning process, or possibly an entire cleaning process. For example, it is conceivable that the display device 45 shows the user options for various cleaning programs that the user can select alternatively. Depending on the selection of a cleaning program, the control unit 6 then controls the cleaning robot 5 for at least one cleaning process of the loading space 3. The various cleaning programs can, for example, require different operating parameters of the cleaning robot 5, so that cleaning is carried out automatically in different ways depending on the selection of the cleaning program.

[0042] The cleaning station 1 further comprises a signaling system 48, which is connected laterally to a side wall 16 of the garage 8 in the manner of a traffic light. The signaling system 48 can be used for various purposes. In particular, it serves to visually indicate to the driver of a respective means of transport 2 when a parking position relative to the cleaning station 1 has been reached. It is understood that the means of transport 2 must be positioned relative to the cleaning station 1 in such a way that the cleaning robot 5 can drive into the loading space 3 of the means of transport 2 from the platform 7. In particular, it is advantageous if there is only a slight, preferably no, difference between the height of a loading space floor 39 of the loading space 3 to be cleaned and the height of the driving plane of the platform 7.

[0043] To protect the support frame 4 from an unintentional impact of a transport means 2 moving into its parking position, it may further be advantageous if the cleaning station 1 has an impact device (not shown in the figures). This is arranged relative to the support frame 4 in such a way that the transport means 2, when approaching the cleaning station 1, first comes into contact with the impact device before colliding with the support frame 4. The impact device can be anchored in a subsurface, for example by means of a foundation. However, in order to be able to set up and operate the cleaning station flexibly without structural changes to the subsurface, it is particularly advantageous if the impact device is stabilized by the dead weight of the transport means 2. For this purpose, the The impact device may, in particular, comprise a battering ram, which is connected at its end to an elongated base plate. The latter is oriented relative to the support frame 4 such that the transport means 2 drives onto the base plate when taking up a parking position at the cleaning station 1, thereby fixing the impact device as a whole relative to the ground 13, forming a frictional connection.

[0044] Furthermore, in the example shown, the signaling system 48 makes it possible to visually indicate to the driver of the means of transport 2 a height difference between the height of the loading space floor 39 of the means of transport 2 and the height of the driving level of the platform 7. For the reasons already mentioned above, this height difference should be minimal, preferably zero, so that the cleaning robot 5 does not have to overcome any height when crossing from the platform 7 into the loading space 3. The height of the loading space floor 39 can be adjusted to the height of the platform 7, in particular, by the means of transport 7, so that the driver can make the adjustment taking into account the signal displayed by the signaling system 48.

[0045] Furthermore, the cleaning station 1 has two door holders 54, one of which is arranged on each side of the platform 7. The door holders 54 serve to lock the doors 55 of the means of transport 2 in their open position when present. This is particularly clearly shown in Figure 1. Due to the extension of the platform 7 into its outer area 42, it is possible to position the doors 55 of the means of transport 2, when present in their open position, to the side of the platform 7 and thus make them accessible for cleaning by the cleaning robot 5. For this purpose, the cleaning robot 5 is positioned outside the garage 8 in the outer area 42 of the platform 7 and activated in such a way that the doors 55 arranged to the side of the platform 7 are exposed to the cleaning fluid and are thereby cleaned.The door holders 54 serve to lock the doors 55 during cleaning, so that cleaning can be carried out reliably. In particular, the door holders 54 can each have a suction cup, by means of which a respective door 55 can be grasped on an outer side by applying a negative pressure. The door holders 54 can be arranged on the support frame 4 in a force-transmitting manner and thus divert forces generated when the doors 55 are locked into the support frame 4. The door holders 54 are preferably arranged such that they are suitable for locking the doors 55 when an opening angle of approximately 90° is present.

[0046] The cleaning station 1 further comprises a sensor 46, which in the shown Example is formed by a camera. This sensor 46 is located on a front edge 30 of the The sensor 46 is arranged on the roof 15 of the garage 8. It is oriented forward toward a front end of the cleaning station 1 or toward the means of transport 2, so that it is suitable for detecting optical information relating to the means of transport 2 and the loading space 3. The sensor 46 is connected in a data-transmitting manner to the data processing device, which, as described above, is embodied as part of the control unit 6 in the example shown. In this way, it is possible to transmit information detected by the sensor 46 to the data processing device and to process it by the latter.

[0047] In particular, the sensor 46 is provided and configured to detect at least one identification feature of the means of transport 2. In the example shown, the sensor 46 is configured to optically detect a license plate number of the means of transport 2, wherein the license plate number serves as an identification feature of the means of transport 2. The information detected in this way is compared by the data processing device with data already available for the same means of transport 2, which data is stored in a database. In the example shown, this database is not implemented locally as part of the data processing device, but is located in the "cloud," with data being exchanged between the database and the data processing device via the Internet.The database contains data that contain an assignment of the vehicle registration number optically detected by the sensor 46 to the means of transport 2, so that in connection with a cleaning of the loading space 3 of the means of transport 2 to be carried out, it is known which means of transport 2 is involved.

[0048] The identification of the means of transport 2 carried out in this way is subsequently used to create a cleaning certificate after the cleaning of the cargo space 3 has been completed, by means of which the completed cleaning is documented. This cleaning certificate is then assigned to the identified means of transport 2 and documented in a database. This can, for example, be the same database from which the vehicle registration number is assigned to the means of transport 2. This type of data processing creates the possibility, in particular, of accessing the cleaning certificate at any time by accessing a user account of a respective customer for the means of transport 2, which belongs to a customer's fleet, and in this way of proving the successful cleaning of the cargo space 3 upon request, for example to an inspection authority.

[0049] Furthermore, the identification of the affected means of transport 2 can be useful in order to control the cleaning robot 5 in a targeted manner for at least one upcoming cleaning process. For example, it is conceivable that the database for the identified means of transport 2 contains information about the type of means of transport 2 and the type of contamination to be expected in the cargo space 3. For example, the means of transport 2 was last used to transport food, which results in certain requirements for cleaning the cargo space 3. Thus, as a result of the identification of the means of transport 2, at least one operating parameter of the cleaning robot 5 can be automatically set for at least one cleaning process, so that the cleaning process can be adapted to the expected contamination and, if necessary, to a predetermined cleaning objective.For example, it is conceivable that for cleaning a cargo space 3 in which food was previously transported, the cleaning fluid applied by the cleaning robot 5 is heated to a specific temperature in order to effectively remove expected contamination of the cargo space 3. It is also conceivable that cleaning is carried out with a view to the next cargo to be transported.

[0050] Furthermore, in the example shown, the sensor 46 is provided and configured to optically detect a height difference between the height level of the loading space floor 36 and the height level of the driving plane of the platform 7 and to transmit the corresponding information to the data processing device. This is configured to process the information and subsequently provide the driver of the means of transport 2 with information, for example by means of the signaling system 48, in order to provide the driver with feedback on the existing height difference. The driver is then able to adjust the height of the means of transport 2, for example by means of a pneumatic system of the means of transport 2. The adjustment is preferably carried out in such a way that there is ultimately no longer any height difference between the loading space floor 39 and the platform 7.

[0051] Finally, in the example shown, the sensor 46 is further provided and configured to optically detect the loading space 3 or walls 38, the loading space floor 39, and / or a loading space ceiling 40 of the means of transport 2. Information detected in this way is forwarded to the data processing device and processed by the latter, thereby enabling the detection of objects in general, in particular obstacles, and / or soiling. The latter may, in particular, be in the form of soiling present on surfaces of the walls 38, the loading space floor 39, and / or the loading space ceiling 40. The data processing device is intended and configured to process the acquired information and to control the cleaning robot 5 depending on the information, i.e., as a result of its processing.

[0052] This control consists in particular in that at least one operating parameter of the cleaning robot 5 is set for at least one cleaning process of the cargo space 3 in question. For example, it is conceivable that local soiling is optically detected by means of the sensor 46 on a wall 38 of the means of transport 2 and, as a result of the processing of the information detected in this way, the cleaning robot 5 is controlled in such a way that it temporarily reduces its driving speed in the longitudinal direction of the cargo space 3 in the area of ​​the detected soiling. As a result, the application of cleaning fluid to the location of the local soiling is increased and the soiling is thus removed in a targeted manner. It is also conceivable that an application rate of the cleaning fluid that is applied locally in the area of ​​the soiling by the cleaning robot 5 ora cleaning nozzle 33 thereof is temporarily increased in order to apply more cleaning fluid to the soiling. In this way, in cooperation between the sensor 46 and the data processing device of the control unit 6, the cleaning robot 5 can be controlled as needed for a respective cleaning process. It is also possible to change at least one operating parameter of the cleaning robot 5 during the execution of a cleaning process and / or between different cleaning processes.

[0053] In the example shown, a further sensor (not shown) is a lidar. This sensor is used to detect the dimensions of the cargo space 3. The information thus obtained can be used to control the cleaning robot 5 to perform the automatic cleaning and / or to adjust at least one operating parameter for at least one cleaning process.

[0054] It is also conceivable to use a sensor, which can be formed by a camera or a lidar, for example, to detect the level of soiling in the cargo space 3 after completion of each cleaning process. For example, it is conceivable that foreign bodies or accumulations of liquid (“puddles”) remaining in the cargo space 3 can be detected by a sensor formed by a lidar. If no soiling is detected, the cleaning is assessed as sufficient and the cleaning is terminated. The result of such a “follow-up inspection” of the cargo space 3 can also be the subject of an automatically generated cleaning certificate, which accordingly not only documents that This ensures that not only the prescribed cleaning was carried out, but also that the desired cleaning result was achieved. For this purpose, it is conceivable that, for example, specific requirements for the cleaning result are stored for an identified means of transport 2. These requirements can be verified by sensory recording using at least one sensor; if the requirements are met, the resulting cleaning certificate can document the cleaning result.

[0055] In the event that a drive of the cleaning robot 5 is unexpectedly prevented from leaving the loading space 3 of a respective means of transport 2 under its own power, it is necessary to remove the cleaning robot 5 from the loading space 3 so that the means of transport 2 is free and can leave the cleaning station 1. Such a failure can be caused, for example, by a chassis 25 being damaged, a power failure, or the like. In order to reliably remove the cleaning robot 5 from the loading space 13, the cleaning station 1 in the example shown has a cable winch 52 arranged on the rear side wall 16 of the garage 8. The cable winch 52 has a bearing roller (not shown) on which a traction cable (not shown) is wound.This traction cable can be connected to the cleaning robot 5 in a force-transmitting manner, so that by means of a subsequent rotary drive of the bearing roller, the traction cable is wound onto the bearing roller, thereby pulling the cleaning robot 5 backwards out of the loading space 3, counter to its main direction 32. The cable winch 52 can be operated manually using a crank or motorized using an electric drive. To ensure continued functionality in the event of a failure of an external power supply, the cable winch 52 can be supplied with electrical energy by means of a battery.

[0056] Furthermore, in the example shown, the cleaning station 1 has a cleaning device 53, which is arranged on an underside of the roof 15 of the garage 8. The cleaning device 53 is intended to apply cleaning fluid to the cleaning robot 5 when it is in its parking position, in which the cleaning robot 5 is parked in the interior 17 of the garage 8, and thus to clean it. For this purpose, the cleaning device 53 can in particular have at least one cleaning nozzle, by means of which cleaning fluid can be sprayed onto the cleaning robot 5 from above. Rinsing with fresh water after the application of cleaning fluid is also conceivable and could be carried out using the cleaning device 53. The space boundary element 18 is preferably closed when the cleaning robot 5 is actively cleaning inside the garage 8.

[0057] As explained above, the cleaning of a respective cargo space 3 is carried out automatically or independently by means of the cleaning robot 5. This is particularly clearly shown in Figures 6 to 8. The cleaning robot 5 comprises a frame 24, which represents a supporting structure for the cleaning robot 5. Furthermore, the cleaning robot 5 comprises a chassis 25, which, in the example shown, comprises two crawler tracks 31 arranged side by side and oriented parallel to one another. The crawler tracks 31 each comprise a self-contained, circumferentially driven conveyor belt or track, so that the cleaning robot 5 as a whole can be moved relative to a surface using the crawler tracks 31. The crawler tracks 31 are arranged on an underside of the frame 24 facing the cargo space floor 38 and can be driven separately from one another, so that the cleaning robot 5 can be moved like a tank control system.In particular, a main direction 32 in which the cleaning robot 5 moves forward during synchronous operation of the crawler tracks 31 can be changed as a result of an asynchronous operation of the crawler tracks 31, wherein the cleaning robot 5 rotates about its vertical axis 35 in the course of this.

[0058] The cleaning robot 5 further comprises a cleaning unit 26, which is suitable for applying the cleaning fluid to the walls 38, the loading space floor 39, the loading space ceiling 40, and the doors 55 of the means of transport 2. For this purpose, the cleaning unit 26 comprises a plurality of cleaning nozzles 33, which are distributed on the frame 24. The cleaning nozzles 33 are oriented at a front end of the cleaning robot 5, respectively to the sides and upwards and downwards, in order to apply the cleaning fluid to the respective corresponding surfaces of the loading space 3. In order to change the orientation of the cleaning nozzles 33 during a cleaning process, in the example shown, a plurality of cleaning nozzles 33 are arranged on elongated nozzle bars 36, wherein the nozzle bars 36 are each pivotably mounted about a longitudinal axis 34. In the example shown, one nozzle bar 36 is assigned to each direction.In this way, it is possible, for example, to operate the cleaning nozzles 33 in a first orientation relative to the walls 38, the loading space floor 39 and the loading space ceiling 40 during a forward movement of the cleaning robot 5 in the main direction 32. After reaching an end wall 51 of the means of transport 2, the drive direction of the crawler tracks 31 is reversed, so that the cleaning robot 5 then moves backwards opposite to the main direction 32 back towards the platform 7. In order to remove previously detached contaminants from the loading space 3, the nozzle bars 36 are pivoted about their respective longitudinal axes 34 before the start of the backward movement, so that the cleaning nozzles 33 are now directed "backwards". In this way, the. further operation of the cleaning nozzles 33, i.e. the spraying of the Cleaning fluid ensures that the contaminants are flushed out of the cargo space 3 in the direction of the platform 7.

[0059] The application of the cleaning fluid by means of the cleaning nozzles 33 is illustrated in Figures 7 and 8 by means of spray cones 41. The adjustment of the nozzle bars 36 is motorized in the example shown, with each nozzle bar 36 being assigned an electric drive. The adjustability of the nozzle bars 36 – and thus the application direction of the cleaning nozzles 33 – is also advantageous for the targeted removal of localized soiling or dirt spots. This is due to the fact that such dirty spots can be sprayed with the cleaning fluid from different directions, whereby the respective dirty spot can be literally "scraped" off the respective surface according to the principle of a high-pressure cleaner. Thus, by changing the application direction of the cleaning fluid, a particularly high cleaning performance can be achieved.

[0060] Furthermore, the cleaning unit 26 comprises a plurality of valves (not shown in the figures) by means of which the supply of cleaning fluid to the individual nozzle bars 36 can be adjusted. The valves can be used both to throttle the flow rate of cleaning fluid and to completely shut off one or more nozzle bars 36. In this way, it is possible to apply cleaning fluid specifically to specific locations in the cargo space 3, for example, in the presence of heavy soiling on the surface of a wall 38 of the means of transport 2, which is not present in the same form on other walls 38.

[0061] Furthermore, it is particularly advantageous if an upper, transversely extending nozzle bar 50, which can be seen in Figure 8, is moved downwards along the frame 24 after reaching the end wall 51 of the means of transport 2 and before the direction of travel of the cleaning robot 5 is reversed. In this way, it is possible to apply cleaning fluid to the end wall 51 by means of cleaning nozzles 33 arranged on the said nozzle bar 50, and thereby also to clean the end wall 51. Accordingly, the cleaning robot 5 is designed such that the said nozzle bar 50 can be moved vertically along the frame 24, for example by means of a rotationally drivable threaded rod. Before the cleaning robot 5 begins to reverse, the nozzle bar 36 is moved upwards again so that it can continue to clean the load compartment ceiling 40 during the reverse movement.To change the orientation of the cleaning nozzles 33, which are arranged on the transverse nozzle bar 50, acts. These cooperate in the manner described above with an electric drive, by means of which the nozzle bar 50 can be pivoted about its longitudinal axis 34. This allows the cleaning nozzles 33 to be aligned with the end wall 51, at least during the downward movement of the nozzle bar 50.

[0062] In the example shown, the cleaning robot 5 further comprises a control box 37, which can in particular accommodate a control unit 6. This is particularly advantageous if, in one embodiment, the control unit 6, which in the example shown is arranged on the support frame 4 or the garage 8, is arranged locally on the cleaning robot 5. Furthermore, the control box 37 can comprise additional switching devices for the local control of the cleaning robot 5.

[0063] The cleaning robot 5 further comprises a sensor device 27 which comprises a plurality of sensors 28. In particular, a plurality of the sensors 28 are formed by distance sensors 29, wherein in the example shown, two distance sensors 29 are arranged on each of the crawler tracks 31. This is particularly clear from Figure 6. The distance sensors 29 can, for example, also be arranged laterally on the frame 24. The aforementioned distance sensors 29 serve to detect a lateral distance of the cleaning robot 5 to the lateral walls 38 of the means of transport 2, i.e. both to the left side and to the right side of the cleaning robot 5. The distance sensors 29 are formed here by ultrasonic sensors. By determining the distances of the cleaning robot 5 to both sides relative to the lateral walls 38 of the means of transport 2, it is possible to align the cleaning robot 5 orthe main direction 32 of the cleaning robot 5 relative to a longitudinal axis of the loading space 3. For this purpose, the information acquired by the distance sensors 29 is sent to the data processing device and processed by the latter. For the travel of the cleaning robot 5 during a cleaning process of the loading space 3, it must be ruled out that the cleaning robot 5 comes into contact with the walls 38 of the means of transport 2, in particular that it collides with them. Therefore, the orientation of the main direction 32 relative to the longitudinal axis of the loading space 3 is important.

[0064] The information acquired by the distance sensors 29 is used to determine the orientation of the cleaning robot 5 within the loading space 3 and to correct it if necessary. Such a correction requires a rotation of the cleaning robot 5 about its vertical axis 35. To accomplish this, the information acquired by the distance sensors 29 is processed by the data processing device in the manner described above and then The chassis 25 is controlled by the data processing device (here indirectly via the control unit 6), so that the crawler tracks 31 of the chassis 25 of the cleaning robot 5 are operated asynchronously. For example, it is conceivable that only one of the crawler tracks 31 is driven while the other crawler track 31 is stationary. It is also conceivable that the crawler tracks 31 are temporarily operated in opposite directions or at different speeds in the same direction. These and other conceivable concepts lead to a desired rotation of the cleaning robot 5 about the vertical axis 35 and thus to a change in the main direction 32 in which the cleaning robot 5 travels when the crawler tracks 31 are operated synchronously. In this way, the cleaning robot 5 can be aligned particularly easily within the loading space 3, so that its travel during a cleaning process runs parallel to the longitudinal axis of the loading space 3.Continuous checking of the distances of the cleaning robot 5 from the lateral walls 38 is conceivable, with a correction of the main direction 32 being able to be carried out repeatedly in the manner described. This makes it possible to align the cleaning robot 5 within the loading space 3 without having to establish physical contact with the lateral walls 38. Furthermore, it is particularly easy to position the cleaning robot 5 at least substantially centrally between the lateral walls 38 of the transport means 2, so that the lateral distances of the cleaning robot 5 from the walls 38 are at least substantially equal on both sides.

[0065] Furthermore, the sensor device 27 comprises further sensors 28, which are formed by distance sensors 29, but are not separately shown in the figures. In particular, a distance sensor 29 is arranged on a front side of the cleaning robot 5 and oriented in the main direction 32, so that a distance of the cleaning robot 5 to an obstacle located in the main direction 32 of the cleaning robot 5 can be detected. In this way, the cleaning robot 5 can be positioned particularly easily relative to the front end wall 51 of the transport means 2, wherein the cleaning robot 5 can be stopped in good time before a collision with the end wall 51. The sensor device 27 also has a distance sensor 29 oriented in the rear direction of the cleaning robot 5, which is also not separately shown in the figures.This can be particularly advantageous for taking up the parking position within the garage 8, wherein a distance of the cleaning robot 5 from the rear side wall 16 of the garage 8 can be detected.

[0066] Furthermore, the sensor device 27 in the example shown comprises a further Sensor 28, which here is formed by a combined temperature and humidity sensor This sensor 28 makes it possible to record information about the temperature and humidity prevailing in the cargo space 3 during a cleaning process. This information is processed, in particular by means of the data processing device of the control unit 6, so that at least one operating parameter of the cleaning robot 5 can be changed depending on the recorded information. The recorded information can also be used to monitor the cleaning itself and thus ensure and document the quality of the cleaning. Corresponding data can be documented, for example, as part of the cleaning certificate described above.

[0067] Additional sensors 28 can, for example, be formed by a pressure sensor or a flow sensor, by means of which information concerning the cleaning fluid can be detected. This makes it possible to determine the flow rate of cleaning fluid being applied, for example, at a nozzle bar 36 or the pressure at which cleaning fluid is sprayed by means of the cleaning nozzles 33. This information can be used in control technology to modify the control of the cleaning robot 5 and to influence the aforementioned operating parameters accordingly. Likewise, malfunctions in the fluid supply 9 can be detected; for example, a sudden drop in the pressure or flow rate of the cleaning fluid can provide an indication of such a malfunction.

[0068] After the cleaning fluid has been successfully applied by means of the cleaning unit 26, it is conceivable that the cargo space 3 is dried at the end of each cleaning. For this purpose, it is conceivable, for example, to apply an air stream, in particular to the cargo space floor 39, and possibly also to the walls 38 and the cargo space ceiling 40, by means of the cleaning nozzles 33 or separate air outlets, whereby any remaining moisture resulting from the application of the cleaning fluid is dried off.
