Definitions

  • the invention relates to a feed device for feeding a mobile device with a material that can be fed through a feed line, a mobile device that can be fed via the feed device and a system comprising the feed device and the mobile device.
  • Automated guided vehicles such as self-propelled wet cleaning robots, processing machines, discharge devices or transport vehicles, etc.
  • AGV Automated guided vehicles
  • the phases of autonomous operation should be as long as possible.
  • the exhaustion characteristics of the AGV are sometimes decisive for the achievable duration of such a phase.
  • solutions with fixedly positioned docking stations for supplying a consumable are known.
  • the AGVs can connect to the docking station under their own power.
  • autonomous operation is limited by the fact that refilling consumables using such a docking station is not practical and therefore requires manual steps.
  • an AGV can be used to transport consumables or requires consumables to successfully complete its task.
  • An autonomously operated cleaning or floor treatment robot consumes, for example, water and/or cleaning liquid during operation. In order for such a cleaning or floor treatment robot to be able to operate autonomously for as long as possible, an autonomous supply of at least water is crucial.
  • AGVs are supplied with the required goods, be it electricity or fluid-based goods or goods with flow properties such as For example, water or an emulsion or bulk material, systems are used in which the AGV works together with a permanently installed docking station. In such systems, the AGV steers to the docking station as soon as appropriate goods are required and uses its drive to couple to the docking station into a coupled state.
  • Examples of such systems for soil treatment are in the WO2017/190784 and the KR20140036653 described.
  • Such systems typically have a soil treatment robot and a permanently installed docking station. Connection elements are each arranged at a specific position on the soil treatment robot and at a position corresponding to this position on the docking station.
  • connection elements are aligned parallel to the installation surface.
  • the corresponding connection elements must be horizontally aligned and precisely coordinated with one another at the same height. The height and horizontal alignment of the connection elements on the docking station necessarily dictate the position and orientation of the corresponding connection elements on the cleaning robot or vice versa.
  • a first inventive step it is recognized that in conventional systems that use a docking station to power a mobile device, it is highly limiting that the docking station only has a single specific and predefined arrangement of connection elements on the mobile device with a horizontal coupling direction can work together. In practice, this means that for different arrangements of the connecting elements on mobile devices, different docking stations must be used, even if the end result is the same product. Furthermore, the horizontal coupling direction specified in known docking stations when feeding goods, especially liquids, can place high demands on the sealing if unwanted leakage is to be reliably prevented.
  • the present invention therefore relates to a feed device for feeding a device that can be moved on a driving surface with a material that can be fed through a feed line, in particular a pipeline.
  • the feed device also includes a plug with at least one electrical plug contact element, which extends towards the free plug end along a plug axis and can be coupled to a plug receptacle of the mobile device by a linear joining movement.
  • the feed device also includes a feed line with a valve and detects a coupled one Condition of the plug with the plug receptacle using an electrical plug contact element. When coupled, the valve on the supply line can be actuated.
  • the feed device comprises a trunk, a feed holder, a movement device and a detection system, wherein the trunk is arranged on the feed line and runs towards the free end of the trunk along a trunk axis and can be coupled to an inlet port of the mobile device.
  • the feed holder holds the proboscis and the plug in a defined position and orientation relative to one another so that when the plug is coupled to the plug receptacle, the proboscis couples to the inlet port.
  • the movement device makes the feed holder with plug and trunk at least height-adjustable and movable in the direction of the joining movement along a joining axis.
  • a detection system is configured to determine a position and orientation of the connector receptacle based on identifying features of the connector receptacle.
  • the feed device is designed, based on the determined position and orientation of the plug receptacle, to couple the plug to the plug receptacle and thereby the proboscis to the inlet connector by a linear joining movement along the joining axis.
  • An advantage of the feed device according to the invention results from the fact that the trunk and the plug are held by the feed holder in a certain relative position and orientation to one another and the feed holder can be moved by the movement device.
  • the feed device according to the invention enables powering of mobile devices, which is less restricted in that the same feed device can be used for different devices with different arrangements of the connection elements on the device, for example at different heights.
  • mobility of the connecting elements plug and trunk is provided by the movement device.
  • the movement device can provide mobility of the connecting elements in three different directions (translatory degrees of freedom) and around one or possibly two axes of rotation (rotational degrees of freedom).
  • the translational degrees of freedom enable the plug and the Trunk in height relative to a driving surface on which the mobile device travels, and in a plane parallel to the driving surface.
  • the rotational degrees of freedom enable the connecting elements to be moved about an axis of rotation which runs parallel to the driving surface or is possibly perpendicular to the driving surface.
  • a movability about a rotation axis running parallel to the driving surface enables the plug and trunk to be tilted towards the driving surface. This makes it possible for the feed device to couple the plug and the trunk with the corresponding plug receptacle and the corresponding inlet port, regardless of their height and orientation on the mobile device.
  • the adjustable inclination for example, complex seals can be dispensed with when supplying liquid or unwanted leakage can be prevented.
  • a further advantage of the feed device according to the invention results from the fact that the movement required for coupling is carried out via the movement device and thus via the movement of the feed holder with the connecting elements. This enables a safer coupling movement compared to systems with a docking station, since the coupling movement is carried out by the movement device and thus by the movement of the connecting elements, trunk and plug. Due to the low moving mass compared to that of a mobile device, for example a cleaning robot, the coupling process or the coupling movement can be controlled in a more controlled manner and in particular by using smaller forces. This can prevent objects from being crushed between the connecting elements to be coupled.
  • the feed device according to the invention can, for example, serve to supply a mobile device as a consumer, fluid-based goods or goods with flow properties as consumable goods via the feed line and the trunk.
  • the trunk is designed as an end piece of the feed line and is used for coupling to the inlet connection, so that fluid-based goods or goods with flow properties can be transported via the feed line and the trunk to the mobile Device can be fed.
  • the feed device according to the invention can serve, if necessary, to supply exclusively fluid-based goods or goods with flow properties, exclusively electrical current, for example for charging a battery, and also fluid-based goods/goods with flow properties at the same time as electrical current to the mobile device.
  • the plug of the feed device can advantageously be a power plug which is designed to supply power and has, for example, male plug contact elements for this purpose.
  • These male plug contact elements for example contact pins, can be surrounded by a sleeve-shaped protective cover so that the contact pins are not freely accessible for touching for safety reasons.
  • the counterpart to the feeder plug is located on the mobile device and is formed by the plug receptacle.
  • the electrical plug-receiving contact elements of the plug receptacle form depressions into which the electrical plug-contact elements of the plug are inserted.
  • An arrangement is also conceivable in which the plug and plug receptacle are arranged interchangeably, for example the plug is arranged on the mobile device and the plug receptacle is arranged on the feed device.
  • the linear joining movement refers to the insertion of the plug into the plug receptacle and the coupled state refers to the state in which the plug is inserted into the plug receptacle until it stops.
  • the linear joining movement is largely determined by the guide wall of the plug and that of the plug receptacle.
  • the plug receptacle which is attached to the mobile device, typically has female plug receptacle contact elements corresponding to the male plug contact elements of the plug.
  • the female plug receptacle contact elements can then be identifying features of the plug receptacle, since, for example, due to their shape or arrangement relative to one another, they make a position and orientation of the plug receptacle recognizable to the recognition system.
  • the detection system can advantageously be based on principles of image capture and image recognition, with a position and orientation of the plug receptacle being determined based on recognition features recognized in captured images.
  • the feed line of the feed device can be tubular or hose-shaped, with fluid-based goods or goods with flow properties being able to be fed to the mobile device via the feed line and one end of the feed line being formed by the trunk.
  • the other end of the supply line can then be connected, for example, to a permanently installed goods supply system (water supply to a building) or a goods storage container.
  • the feed line has a valve that can be actuated, for example, by the feed device.
  • the valve can assume an open position and a closed position, with the ability to switch back and forth between the positions. In the open position the goods can be fed via the feed line and in the closed position this is prevented.
  • the valve is preferably located in the area of the feed holder where the trunk is held.
  • the feed device can detect a coupled state, for example, by making contact between an electrical plug contact element of the plug and an electrical plug receptacle contact element of the plug receptacle, with the establishment of contact between the contact elements being possible only in the coupled state.
  • the trunk forms the end piece of the feed line and is inserted into the inlet connector.
  • the trunk and the inlet connector are in a coupled state when the plug and the plug receptacle are in a coupled state. In the coupled state, the trunk is inserted into the inlet port and a fluid connection for supplying a product via the supply line can be established.
  • the trunk can optionally also have one or more seals, which enable a tighter or more positive coupling of the trunk and inlet connection.
  • the feed holder is designed so that it holds the plug and the trunk in such a way that when the plug is coupled to the plug receptacle, the trunk is inserted into the inlet port and that the coupling of the plug to the plug receptacle corresponds to the coupling of the trunk to the inlet port comes along.
  • the movement device can advantageously be formed by a robot arm which is attached to a base plate in a height-adjustable manner and has at least one arm segment.
  • the arm segment is then attached to the base plate so that it can pivot about an axis of rotation, and in the case of several arm segments, these are each connected to one another so that they can pivot about an axis of rotation.
  • the feed holder can advantageously be attached to an outermost region of an arm segment so that it can pivot or rotate about at least two mutually orthogonal axes of rotation.
  • the feed device is designed to determine the position and orientation of the plug receptacle using the detection system. Based on this, the movement device enables a linear movement of the feed holder along the joining axis to couple the plug to the plug receptacle, thereby accompanying the coupling of the proboscis to the inlet port.
  • the feed device has a control for partially or fully automatic movement of the feed holder.
  • the control is connected to drive units, which automatically provide the rotation or pivoting of the feed holder via a control line.
  • the control is also communicatively connected to the detection system for detecting a position and orientation of the plug receptacle.
  • the valve of the feed line is also connected via a control line to the control of the feed device for its actuation.
  • the plug can be designed to enable a communicative connection to a control of the mobile device in the coupled state via one or more electrical plug contact elements, so that the control of the Feeding device can interact with the control of the mobile device as part of the supply of the mobile device.
  • the feed holder can hold the trunk and the plug with the trunk axis aligned parallel to the plug axis.
  • the joining axis is inclined towards the driving surface of the mobile device in the direction of the joining movement, in particular at an angle of inclination in the range of 12° to 32°.
  • An angle of inclination of around 22° is particularly advantageous here.
  • This inclined orientation of the joining axis simplifies the supply of the mobile device with a fluid-like material, for example, in such a way that the requirements for a positive coupling of the trunk with the inlet nozzle are reduced and the fluid-like material flows back from the filler neck back into the trunk, or into the environment is prevented.
  • the feed device is configured to determine the joining axis based on the determined position and orientation of the plug receptacle, the movement device being designed to make the feed holder with plug and trunk movable along the specific joining axis. For example, based on the recognition of the identifying features of the plug receptacle in a recorded image and the known design of this same plug receptacle, the alignment of the plug receptacle on the mobile device can be concluded. The joining axis can then be determined based on the alignment determined in this way. This enables the plug and the trunk of the same feed device to be coupled to plug receptacles and inlet connectors that are attached to the respective mobile device with a different orientation.
  • the free ends of the plug and trunk are arranged with an offset to one another in the direction of the joining axis.
  • the offset corresponds to an offset in the direction of the joining axis between the free ends of the plug receptacle and the inlet connector on the mobile device.

  • the locking device can only be activated when the plug is coupled to the plug receptacle. This means that the valve for supplying the material can only be opened when the plug is coupled to the plug receptacle and locked.
  • the locking device and the locking elements can alternatively also be arranged on the plug receptacle, in which case the locking element receptacles are arranged on the plug.
  • the movement device is designed to make the feed holder with plug and trunk movable partially or fully automatically in a limited movement mode and an unrestricted movement mode
  • the feed device is configured to couple the plug with the plug receptacle through a movement of the plug in a pre-position relative to the plug receptacle in the restricted movement mode and a linear joining movement of the plug in the unrestricted Movement mode.
  • the restricted movement mode refers to a movement mode in which the feed holder is moved with greatly reduced dynamics and/or force.
  • a threshold value can be set for the maximum applicable force for moving the feed holder.
