Definitions

  • the invention relates to a trolley and a method for moving cleaning robots in and out of the trolley.
  • the invention relates to a cart for storing cleaning robots and a method for loading and unloading cleaning robots into and out of the cart.
  • a cleaning system In particular for cleaning larger commercial floor areas such as sales areas in fashion stores, a cleaning system is used that has a fleet of several autonomous or self-propelled cleaning robots and one or more base stations that are designed to empty and supply power to the cleaning robots.
  • a cleaning station in the form of a robot for transporting self-propelled cleaning robots with a drive device for autonomous movement over a floor surface is known.
  • the robot has a sensor device for detecting its surroundings, a storage device for the cleaning robot and a movement device for moving the cleaning robot, which is designed in such a way that it can pick up one of the cleaning robots from the floor surface and place it in the storage device of the robot.
  • the disadvantage here is that the robot cannot simply be pushed manually to a place of use. In particular, it is not possible to transport this robot over several floors without an elevator. The flexibility and diversity of use of the robot is severely restricted as a result.
  • the robot is very expensive and therefore not well suited for use in the cost-sensitive cleaning industry.
  • the invention therefore faces the problem of providing a cleaning station that has a high degree of flexibility and variety of use with the simplest operation, is inexpensive, and whose cleaning robots are protected from external influences during inactivity.
  • the cleaning robots are safely stowed in the car and protected from external influences by a door.
  • the trolley is inexpensive because it can be moved manually using the handle. Electrical drive devices are not necessary to move the carriage.
  • the trolley is inexpensive and can be easily and flexibly brought to the place of use by cleaning staff.
  • the repositioning of the carriage does not require any multiport robot special operating skills.
  • the car is less susceptible to errors such as software problems.
  • Information on position and direction refers to an operational set-up or working position of the trolley.
  • the following advantages are generated by the simple, manual mobility of the trolley by a user from one place of use to the next: Increased application flexibility and variety of the cleaning system, better transportability of the trolley because the cleaning system is light, compact and manoeuvrable.
  • a reduction in the costs of the car is achieved since no complex navigation technology or software has to be installed and/or used in the car. Easier operation of the cart is provided so that no robotics knowledge is required to move the cart to the job site.
  • the car is easy to understand and self-sufficient. Cleaning staff with little knowledge can handle the trolley.
  • the trolley has good robustness, which reduces the trolley's susceptibility to external influences such as impacts.
  • the car does not require any navigation elements that can be damaged.
  • the door element forms a housing which, when the door element is closed, completely encloses the interior of the car.
  • the cleaning robots stowed in the trolley, the storage compartments, the lift system and the extraction platform are then completely encased.
  • the door element protects the individual cleaning robots from theft or damage from external influences during storage in the trolley.
  • the trolley serves as a base station for a number of cleaning robots. Together with the cleaning robots, the trolley forms a cleaning system in the form of a mobile cleaning station. A fleet of multiple cleaning robots is stowed inside the mobile cart outside of the cleaning phase when the cleaning robots perform cleaning tasks.
  • the trolley has a number of storage compartments corresponding to the number of cleaning robots, in which the cleaning robots are stored outside of the cleaning phase and which each have their own charging contact for supplying energy to the cleaning robot stored in it.
  • the trolley has an energy supply unit which is designed to supply the trolley and the cleaning robots stowed in it with electrical energy.
  • the energy supply unit is designed to supply electrical energy to all of the components of the trolley and also to the energy storage units of the cleaning robots.
  • the trolley can have a mains connection for charging the energy supply unit.
  • the mains connection can be easily disconnected from the mains if necessary the car is to be moved to an operation site.
  • the energy supply unit is arranged in and/or on the carriage in the form of a rechargeable battery. The energy supply unit then enables a cleaning operation which is largely self-sufficient from existing connections of a building power supply network.
  • an accumulator in the case of an accumulator, the omission of a mains connection cable, which would otherwise be required, increases the degree of mobility of the car.
  • the use of an accumulator as an energy supply unit can be advantageous because commercial areas usually have a manageable number of sockets and the trolley can be positioned freely on the area to be cleaned and is not tied to sockets locally. In this way, the most sensible positioning on the surface to be cleaned can be selected with regard to efficient use of the cleaning robot fleet.
  • the charging contact is preferably connected to a corresponding contact on the cleaning robot located in the storage compartment when the cleaning robot is arranged in the storage compartment.
  • the energy storage unit of the cleaning robots is charged via the connected charging contacts when they are arranged in their respective storage compartment.
  • the charging device can bring about contactless charging of the energy storage unit of the cleaning robot. Manually initiated loading of each individual cleaning robot is no longer necessary.
  • the suction system is designed to remove dirt from the cleaning robots that result from their cleaning operation. This can be superficial dirt on the housing of the cleaning robot.
  • the suction system can be designed to clean the sensors and cleaning elements of the cleaning robots from dirt. Such cleaning functions are preferably integrated into the foldable suction platform.
  • the suction system is designed to empty dirt containers of the cleaning robots, in which the cleaning robots collect dirt picked up during the cleaning operation.
  • the trolley preferably has a collecting dirt container in which the dirt sucked out of the cleaning robots is collected.
  • the collecting dirt container is preferably detachably connected to the trolley, so that it can be removed from it if necessary. It is preferably provided with a handle for removal from the trolley.
  • the suction system preferably contains a fan that is designed to generate an air flow when activated, by means of which the cleaning robots can be emptied.
  • the suction system preferably has a suction opening that is integrated into the suction platform and a suction channel that connects the suction opening to the dirt collection container.
  • one of the cleaning robots can be emptied by means of a suction flow generated by the fan when it is positioned on the suction platform.
  • the cleaning robots that can be stowed and transported in the trolley according to the invention are preferably suction and/or wiping robots, more preferably suction robots that are autonomous and self-propelled.
  • suction and/or wiping robots Preferably at least two, preferably at least 3 to 15, more preferably 4 to 10 cleaning robots can be stowed in the trolley, i.e. can be positioned in a respective storage compartment.
  • the trolley can be easily moved using the transport wheels. In order to get to a place of use, it is sufficient for a user to push it there.
  • the carriage also has a handle by means of which the carriage can be moved as a whole with the aid of the transport wheels. This further simplifies moving the cart to the job site.
  • the foldable suction platform and the foldable receiving element preferably lie on a base on which the transport wheels stand, based on an operational set-up position of the trolley.
  • the receiving element and the suction platform can preferably be folded by 90°. This can be made possible by appropriately attached hinges.
  • the foldable suction platform and the foldable receiving element preferably lie flat on the ground when folded out.
  • the foldable receiving element is preferably segmented and preferably has two receiving element segments.
  • the suction platform is preferably arranged between two receiving element segments and separated from them.
  • the two receiving element segments and the suction platform are preferably dimensioned in such a way that a cleaning robot moves over the two receiving element segments with its edges and its body extends above the suction platform between the two receiving element segments. It is thus possible for the receiving element to be moved vertically in order to transport the cleaning robot, which is arranged on its wheels on the receiving element segments, to one of the storage compartments without the suction platform also having to be moved.
  • the storage compartments are stacked vertically one on top of the other. They are preferably mounted detachably from one another. This further saves space on a floor on which the carriage is placed.
  • the foldable receiving element can be moved vertically in the unfolded state, relative to an operational set-up position Of the car.
  • the lift system is designed to automatically move the receiving element vertically and has an electric motor, for example.
  • the trolley preferably also has an operating panel which is designed in such a way that a user can operate the trolley interactively. For example, the user can use the control panel to start a cleaning mode in which the cleaning robots stored in it are removed from the trolley to carry out their cleaning tasks.
  • the trolley preferably has a controller that is designed to start the cleaning mode immediately after activation. Alternatively or additionally, a timer can also be stored in the controller, which ensures that the cleaning mode can be started at a later point in time, if desired. After activating the cleaning mode, the user can leave the area to be cleaned, since the trolley and the cleaning robots now carry out the activated cleaning independently. No further work steps are necessary to start and end the cleaning, the cleaning system continues to work independently.
  • the controller is preferably designed to automatically control the introduction and removal, suction and, if necessary, cleaning of the cleaning robots.
  • the carriage preferably also has adjustable blocking elements which are designed to block the transport wheels in a blocked state and to release the transport wheels in an unblocked state.
  • the carriage can be fixed on a cleaning surface so that accidental bumping and/or displacement of the carriage during cleaning operation is prevented.
  • the adjustable blocking elements are preferably fitted with mechanical blocking elements.
  • the blocking elements are preferably designed in such a way that they can be fixed or released by the user's foot. This makes it easier to handle.
  • the trolley also has a lock which is designed to secure the door element. This further protects the cleaning robots against theft or damage from external influences. Unauthorized opening of the trolley and stealing of the cleaning robots by unauthorized persons is still prevented.
  • the door element is preferably designed in such a way that it can be opened and closed manually.
  • the door element is preferably designed as a sliding door which can be slid into an intermediate space between an outer wall and an interior of the car.
  • the cart may have guide rails between the interior and the exterior walls to assist in sliding the sliding doors. As a result, the open car takes up less space than if it had hinged doors.
  • the door element preferably has one or more handles, with the aid of which the front of the trolley in the form of the door element can be opened in the form of two sliding doors which can be slid outwards.
  • the door element can be opened and closed automatically.
  • the door element can be opened automatically by operation via the control panel.
  • the door element can continue to be automatically lockable via the control panel.
  • the door element is automatically closed by means of the control of the carriage after all cleaning robots have been introduced into the carriage at the end of the cleaning phase.
  • the carriage has one or more electric motors which are designed to automatically open and close the door element.
  • the suction platform and/or the receiving element can be folded out and in automatically. This is preferably also implemented via one or more electric motors.
  • the carriage preferably has electronic components such as an infrared interface IR, which are designed to support a cleaning robot arranged on the suction platform or the receiving element in positioning itself correctly on it for suction.
  • electronic components such as an infrared interface IR, which are designed to support a cleaning robot arranged on the suction platform or the receiving element in positioning itself correctly on it for suction.
  • the trolley preferably has a communication system for data exchange with the cleaning robots.
  • the communication system of the car is designed for wireless data transmission, for example as a WLAN or Bluetooth module.
  • the communication system can be designed to exchange data with an external electrical device that is used to control and/or monitor the car.
  • an external device can be, for example, a personal computer, a smartphone, a smartwatch or a tablet.
  • the carriage is preferably of modular design. That is, it has a modular architecture. As a result, it does not always have to be transported and used as a whole, but a needs-based, modular adjustment of the number of cleaning robots used and thus a reduction and/or increase in capacity is possible. This increases again the versatility of the car.
  • the carriage preferably has extension modules, which can each be placed on the storage compartment that is located at the highest vertical height and can be fixed there with the aid of connecting elements.
  • the expansion modules each have a storage compartment including charging contact and connecting elements, with the lift system on the car being adaptable to the new situation by expanding its end position.
  • the trolley can thus be expanded to accommodate n cleaning robots to n+x cleaning robots with x expansion modules if the size or requirements of the floor area to be cleaned should change or if the trolley is used on different areas with different requirements. Furthermore, the transport of the trolley is simplified, since the total volume and weight can be reduced through the targeted removal of expansion modules. This is particularly advantageous when transporting the system across different floors without an elevator.
  • the carriage may have a LiDar reflector or a beacon such as an IR beacon.
  • a LiDar reflector or a beacon such as an IR beacon.
  • the trolley starts to deploy the individual cleaning robots onto the surface to be cleaned.
  • the robots are automatically brought out of the storage compartments onto the surface to be cleaned with the help of the mobile lift system. While the cleaning tasks are being carried out, the individual cleaning robots on the trolley can be sucked off, cleaned and/or temporarily charged.
  • the cleaning robot in question drives onto the suction platform, positions itself there and is sucked off via the suction system of the trolley, with the suction flow for emptying the cleaning robot being generated by the fan.
  • additional cleaning functions can be performed on the cleaning robot by the suction platform. These include, for example, functions such as cleaning brush rollers, sensors or similar devices of the cleaning robot.
  • the cleaning robot in question is placed in a free storage compartment with the help of the movable lift system. Opportunity charging takes place in the storage compartment via the existing charging contact. After charging is complete, the cleaning robot is brought back to the surface to be cleaned via the lift system in order to continue its cleaning task.
  • a quick-charging module is arranged on the suction platform, which is set up to quickly charge a cleaning robot during emptying and/or cleaning.
  • the cleaning robot has to find the cart: If the cleaning robot had an existing map at its disposal at the start of the cleaning, the current position of the cart was defined as the starting point on this map, so that the cleaning robot can find the cart itself in order to be brought in. If no map was available when the cleaning started, the position of the cart should be set as the zero point of a map newly constructed by the cleaning robot.
  • the trolley can emit the guide beam such as the IR guide beam, which enables the cleaning robots to locate and approach the trolley exactly.
  • the cleaning robots are brought into the trolley using the moveable lift system.
  • the cleaning robot is preferred over the Introduction subjected to a suction and, if necessary, cleaning process, so that the cleaning robot is stowed empty and clean in one of the storage compartments of the car.
  • the user can remove it from the area to be cleaned. To do this, the user folds in the foldable receiving element of the lift system and the foldable suction platform again and closes the door element, which he can preferably lock.
