Definitions
- the invention relates to a method for controlling a cleaning head an automatic cleaning device Window surfaces of a building, the cleaning head with is connected to a frame that is in the horizontal direction (X direction) and in the vertical direction (Z direction) along the Facade is movable and positioned in front of a window surface and wherein the cleaning head opposite the frame towards the cleaning window surface to and from this (Y direction) as well as in the other two directions perpendicular to this (X direction, Z direction) is movable (see DE-A-2 435 547).
- the frame is with ropes on a crane or a trolley suspended, which is movable on rails, which on are attached to the roof of the building.
- the crane does this Rack from window row to window row, so that the cleaning processes there can be executed.
- the present invention is based on the object Procedure for automatic control of the cleaning head over specify the window surfaces to be cleaned.
- control system is divided into several Control modules on the frame, the cleaning head hold the manipulator and the cleaning head itself.
- the basic data of the building to be cleaned up based on the blueprint in a table the It is divided into columns and rows.
- the horizontal Rows represent the window position and the window geometry, while the columns indicate the vertical window rows.
- This basic data is expediently created with a spreadsheet program or a database system.
- the frame of the automatic cleaning device hangs - as described above - preferably over ropes on a crane or one Trolley and is preferably in vertical rails of the Building facade, i.e. the frame is in the Z direction the respective column of the facade positioned in front of the individual windows, so that the cleaning process can be carried out there can.
- the frame from the associated vertical guide rails threaded out and offset in the X direction so that the frame in the vertical guide rails of the next facade column can be threaded.
- the frame is based on of the facade data, which is preferably recorded in tabular form positioned a window that the cleaning head when feeding in the Y direction, i.e. when moving in towards the building, preferably about the middle of the window.
- the facade data are not critical.
- this is done so that the cleaning head is in the retracted position when the The frame is positioned in front of the window so that the cleaning head about to move to the middle of the window.
- the cleaning head is attached to the window surface along the Y axis.
- the cleaning head is in three mutually perpendicular Movable directions. This is done in a preferred embodiment of the invention accomplished in that the cleaning head on preferably two pneumatic ones arranged side by side Piston / cylinder assemblies is attached, the piston stroke executes the infeed movement to the window surface.
- the piston / cylinder assemblies also by other suitable ones Drives that can be replaced are in turn preferred Embodiment of the invention attached to a sled, on a guide rail running in the Z direction is arranged movably.
- the training can be made so that on End of the guide rail are each pulleys over which For example, timing belts run on both sides of the Sleds are attached.
- This timing belt is made by one associated motor driven.
- the Z axis designated guide rail running in the Z direction two sleds is attached, which in turn is on two in horizontal X-direction guide rails that sit hereinafter referred to as the X axis.
- the Drive preferably via toothed belt attached to the slide, which run over pulleys and have their own drive motor driven for the X axis.
- the Y-axis is preferably driven by force. This means that the cleaning head after activation of the Y axis is pushed forward with a small force and when Reaching the window comes to a standstill by itself.
- the backward movement into the starting position can, for example done by spring force.
- the Cleaning head due to its own weight in the retracted Starting position can slide back, which is what the cleaning head holding piston run slightly obliquely upwards.
- the Y position is monitored using a device arranged for this purpose Position measuring system.
- the X and Z axes continue to run Edge search mode for the center of the window and described in more detail below stop there.
- the Y axis By activating the Y axis the Cleaning head placed on the window pane.
- the invention provides that the cleaning head is now preferred rectilinear in the edge search mode either in the X direction or is moved in the Z direction over the window area until it hits one Reached window edge, preferably runs onto a window edge.
- the cleaning head is now in one of the Z directions associated window edge follow mode preferably an edge follow mode along the window edge in one in the X direction effective edge search mode moves until the cleaning head is on the second edge of the window comes up, making it a corner position of the Window has reached.
- a sensor can be provided that the reaching of Window edge detected, and a signal to the control device emits the cleaning head accordingly over the window surface controls.
- the control device in the edge search mode the motor assigned to the associated axis Specifies target speed, with the specific traversing speed according to those necessary for the respective window pane Conditions and the distance from the expected Window edge aligns.
- the edge search mode only an axis, the X or Z axis, with the specified target speed driven while the other axis on one is held in a fixed position. This can continue either in the Edge follow mode described below happen or position controlled.
- the Cleaning head on a window edge in contact with the Window edge guiding element of the cleaning head preferably whose frame compared to the inner solid structure of the Cleaning head, for example a brush assembly, moved the magnitude of this shift from a measurement or sensor system and the one referred to below as the "sensor stroke" Measured value is supplied to the control device.
- the frame is preferably elastic relative to the inner one fixed structure, for example by suitable spring devices, between the rectangular frame and the inner solid structure are effective on all four sides.
- the associated with the respective axis Sensor stroke can be determined whether the cleaning head is on a free area, whether it is on an obstacle (window edge) hit or whether it is moving along a window edge.
- the preferably elastically mounted element of the cleaning head it doesn't necessarily have to be its frame, but it can also, for example, of the frame protruding contact elements elastically displaceable or deflectable his.
- the drive of the X axis and the Z-axis speed controlled i.e. in open space the cleaning head with a predetermined target speed moved over the disc.
- this target speed of the cleaning head in Dependence on the displacement detected by the sensor stroke of the elastic frame of the cleaning head when it hits it one window edge braked to zero. It is preferred that when the sensor device of the cleaning head Impingement on a window edge recognizes the one specified by the computer Speed proportional to the sensor stroke or deflection is reduced to a standstill of the movement axis. If, for example, a speed of 30% of the maximum value the drive remains at 30% of the maximum Sensor hubs stand.
- the ratio between the specified speed and the sensor stroke too can be disproportionate.
- the cleaning head runs along a window frame up to moved the window frame perpendicular to this, it follows the window frame automatically in the edge follow mode in which the Cleaning head with a given force against the window frame is pressed. This means that the cleaning head at this movement so abuts the frame that the elastic stored frame of the cleaning head around a predetermined Value, d. H. a predetermined sensor stroke, from the starting position is deflected. This sensor stroke or this elastic Displacement of the frame is done by the associated drive motor upright during the movement in this direction receive.
- the Z-axis drive After reaching the opposite corner, taking the cleaning head for example the vertical edge in edge follow mode followed while driving the Z axis in edge search mode the Z-axis drive now goes into edge follow mode over, while the X-axis is controlled so that the cleaning head is moved a predetermined distance.
- This route can in a preferred embodiment of the Invention amount to about 90% of the cleaning width of the head.
- the target position is reached with the help of a position counter determined.
- the sterndrive is actuated from this position, whereby the Z axis is in edge search mode while the X axis is controlled at the same time. This is done with the help of a Position counter, which enables the associated computer, to compensate for a drift. It is proposed that the motor is provided with an encoder that a specific Number of pulses (e.g. 512) generated per engine revolution. Out These pulses are determined by a position counter analog values that the computer can process quickly, the engine then the corresponding correction signals are there. This means that the Control in practice emits tiny control signals that are used for Cuff the specified position of the cleaning head. The quick reaction of the engine is due to the combination of the digital with the analog system.
- a Position counter which enables the associated computer, to compensate for a drift.
- the motor is provided with an encoder that a specific Number of pulses (e.g. 512) generated per engine revolution. Out These pulses are determined by a position counter analog values that the computer can process quickly, the engine then the corresponding correction signals are there
- the Cleaning head pushed back to the edge and the X axis again offset by 90% of the head width, whereby the entire window area is cleaned. Finally, after the To clean the entire pane the cleaning head is lifted off and move to the next window.
- a window 2 m high and 1.50 m wide should be cleaned.
- the cleaning head is 0.2 m from the lower edge and Placed on the window 0.2 m from the left side edge.
- the X axis is traversed at approx. 50 mm / s. This corresponds to a control voltage of approx. -1.5 V (minus, because is driven to the left).
- the Z axis is at the position 0.2 m above the bottom edge of the window held. If the engine is replaced by the usual one Drift of the controller runs away, this is done by the controlling computer corrected and a speed signal in the to be corrected Direction generated. Receives the position information the computer from the position counter.
- the control voltage is used to ensure the position the X axis to -5 V, so that a sensor position of approx. 6 mm.
- the Z axis starts in edge search mode.
- the X axis is controlled so that the sensor stroke at the window edge is constant remains.
- the Z axis also hits the window edge it stops.
- Both axes are now in edge follow mode. By Increase the control voltage on both axes to approximately -8 V. the cleaning head is pushed into the corner of the window.
- the hub the sensor is about 10 mm in both axes.
- the Z axis is controlled with a voltage of approx. 3 V, which is the cleaning head runs upwards at approx. 100 mm / s. this means also the transition to the edge search mode.
- the X axis remains in edge follow mode.
- the Z axis When the upper edge of the window is reached, the Z axis remains at one Stand the sensor stroke of approx. 3 mm again.
- the Control voltage of the Z axis By increasing the Control voltage of the Z axis to 8 V, the cleaning head is in the top left corner of the window.
- the X-axis is now controlled and 90% of the cleaning width move the head. This is done by a control voltage from approx. + 6 V, which is reduced to 0 V when the Target position has been reached.
- the Z axis runs down again after a control voltage -6 V is applied. Are down during the run Both axes in edge search mode, with the X axis simultaneously is position controlled. This is done with the help of the position counter, which enables the computer to drift compensate.
- the X axis moves the cleaning head again by 90% of its head width. It is then cleaned up again. This continues until the X axis, which is constantly in the Edge search mode was, meets the right edge of the window. Is if this is the case, there is a final vertical cleaning movement with finally pressing the cleaning head in the lower right corner of the window. This ensures that the whole pane is cleaned.
- a sensor system is therefore used to control the cleaning head used that determines whether the cleaning head is on an edge of the window.
- the sensors determine the displacement the frame of the cleaning head, which is opposite its inner fixed structure in the X and Z directions is mounted so that it around a certain distance, for example shifted by about 12 mm can be. This is done by a redundant position measuring system, e.g. a potentiometer and the control electronics fed.
- a head control Position counter used, which is then effective if the cleaning head is not along a window edge emotional.
- FIG. 1 The figures show a frame in a largely schematic manner 1 on ropes 2 along a building facade, not shown hangs, which is attached to frame 1 via crane adapter 3 are.
- Frame 1 is with an integrated water treatment system and control provided without this in the figures is shown.
- the frame 1 is provided with rigid support legs 4, the Ends 5 in vertical guide rails, not shown are guided, which are attached to the building facade or in this
- the invention is however not based on such Leadership limited.
- a cleaning head 6, for example provided with brushes can be on one or two piston / cylinder arrangements 7 attached with which the cleaning head along the Y axis (see Fig. 2) in contact with a window pane to be cleaned can be advanced.
- the backward movement takes place through the weight of the cleaning head or by another suitable device in the powerless state of the piston / cylinder arrangement.
- the cleaning head 6 can also be, for example is an ultrasonic cleaning head, and instead of one pneumatic piston / cylinder arrangement can also for example a hydraulic arrangement or a suitable other drive arrangement be provided.
- the cleaning head 6 and its drive device are in one Carriage 8 attached, which is displaceable on a guide rail 9 sits, which is referred to in Fig. 1 as the Z axis.
- the Z-axis 9 is in turn held by two slides 10 in turn on two horizontally running guide rails 11 slidably seated, which is referred to in the figures as the X axis are.
- pulleys each with a drive belt runs, the ends of which on the slide 8 and the slide 10th are attached.
- the belts are driven by a drive motor 12 of the Z axis or a drive motor 13 of the X axis. This will the cleaning head 6 according to the control method according to the invention moved over a window pane to be cleaned.
