    The invention relates to a device for leveling of fillings and building materials.
    Such a device is often referred to as a leveling device and serves to smooth a surface in such a way that a flat, as exactly horizontal surface is formed. This is done in practice long, straight slats which are pulled over the floor. Therefore, these leveling devices are also referred to as pullers. In order to create an exactly horizontal surface by this removal, various devices and methods are used.
    Building materials in the form of beds are used, for example, for the thermal insulation of floors in house construction. Another application is the insulation of a swimming pool down. In this case, a well-insulating, lightweight material in the form of small pieces is often mixed with cement or other hardening material (binder) and applied or applied in the space or surface to be insulated. Dry fillings are also used (without cement or binder) for dry screed systems. Lightweight plastics such as foam or polystyrene are particularly suitable as insulating materials of the bed, but also organic or mineral insulating materials in particulate form are conceivable, such as e.g. Expanded glass or swelling stone body.
    The main application of the subject invention is the leveling of "Styrofoam concrete". or similar developments such as Thermotec® of Thermotec Vertriebs GmbH. However, the invention can of course in general for the production of flat / horizontal surfaces of loose materials (insulation materials, sand, gravel ...) or of viscous, self-curing suspensions (lightweight concrete, concrete screed ...) are used.

    So far, such activities are often performed with simple rulers or bars. The disadvantage is that the measurement and alignment is very laborious and time-consuming and that without sufficient dimensional orientation often not the necessary accuracy is achieved. Therefore, systems have been developed in which a peel strip is rotatably mounted on a support mounted in space.
    DE 29922048 (Ul) shows a device for level installation of dry fillings. First, a support is mounted on a bottom plate at the bottom of the room (preferably in the middle). This is vertically aligned manually manually. The aid is a laser target plate for scanning the meter crack and a rotating laser, which is set to the meter crack. On the support a ruler (honing strip) is manually height adjustable. The ruler is designed in two parts and can be manually adjusted in length during removal to reach all corners of the room. At the front end of the ruler is a spirit level dragonfly to control the horizontal alignment of the ruler and correct manually if necessary.
    The disadvantage is that before removing a support must be mounted in the room and the device must be aligned manually. What needs to be repeated in each room, or in a large room must be repeated several times, when the size of the room exceeds the reach (full length) of the ruler. Another disadvantage is that the device must be removed after completion of leveling again. As a result, the space at which the support was mounted remains free of bulk material and must be manually filled and smoothed.
    DE 10 2006 058 246 A1 shows an apparatus, which has been improved in some respects, for leveling bulk material. A support is also mounted in the room, preferably on the floor with bracing.
    Page 2 3/27 Μ 1678 ceiling, however, it is also intended to be mounted to the wall, which, while restricting the working area, leaves no gap where the device is otherwise mounted to the floor. The support is manually aligned with the aid of measuring devices and adjusting devices. Attached to the post is a bipartite, torsion-resistant arm that can be swiveled around the device. At the free end of the arm a peeling sword is rotatably supported by a vertical downwardly extending stem. By installing the support in the middle of the room, a working area of approx. 30m2 can be covered. Optionally, a height adjustment device is provided in order to keep constant during the removal of the height at which the puller is located. This is achieved by measuring the height and automatic height correction by an electrically operated spindle which adjusts the position of the stem relative to the arm.
    The disadvantage, in turn, the necessary assembly and alignment work and limited workspace. An advantage over DE 10 2006 058 246 A1 is that the working height can be adjusted automatically. The disadvantage remains that the horizontal alignment of the peel strip is done manually.
    The object underlying the invention is to provide a device with which it is possible to produce a precisely horizontal surface in a simple manner after the application of a bed of light material. The leveling work should be able to be performed by a person with significantly less effort and physical effort compared to known manual methods, without having to perform consuming and time-consuming assembly or surveying. For solving the problem, it is proposed to design a pull-off element with the aid of sensors and actuators in such a way that it
    Page 3 4/27 Μ 1678 always on the same horizontal plane, regardless of the movements of the operator.
    The peeling element consists of an elongated peel strip and a variable in length stem which is designed as a telescopic rod. This telescopic rod is preferably connected at its lower end via a hinge with the peel strip. This joint is adjusted via an actuator or more actuators in such a way that the Abziehleiste is always exactly aligned horizontally. The necessary data is obtained from these actuators by suitable sensors which detect the spatial orientation of the wiper strip. Thus, a control loop is formed, in which the signal of the sensors serves as a manipulated variable for the actuators.
    There is another sensor on the telescopic pole that is capable of detecting the altitude at which it is located. This sensor is used to control an actuator, which determines the length of the telescopic rod. The goal is to keep the honing strip at a constant height. So if the stem is held higher by the user, the height at which the sensor is located at the upper end of the telescopic rod changes. The information of the sensor is used to change the length of the telescopic rod by the actuator in the telescopic rod. So if the stem is held higher, the length of the telescopic pole is extended by the actuator to the same extent. As a result, the Abziehleiste always remains at the same height.
    By the two actuator / sensor combinations is achieved that, regardless of the orientation of the stem relative to the vertical and with respect to the height at which it is held, the Abziehleiste is always aligned with respect to the space constantly high, horizontal plane.

    The subject leveling device offers several advantages over the prior art. • Time savings, since complex surveying and / or assembly work is eliminated. Tests have shown that a processing time of at least half is achieved compared to conventional methods. • Cost savings, as a person can carry out the leveling work and the significantly reduced working time can save additional labor costs. • Work comfort and health aspects, as the leveling work can be carried out standing up and eliminating work in a stooping position or on the knees.
    In a particularly preferred embodiment, a support element including carrying vest is additionally used for holding the Abziehelements. The support element may preferably be a parallel-static articulated arm. Such support elements in conjunction with a carrying vest are known in the art and are used in film cameras to allow a smooth camera guide. This device with camera with support arm and vest is also known as Steadycam. The structure of such a system is known for example from US 5360196 (A). The use of this support device in conjunction with a leveling device, however, is new and offers the following advantages. Increased comfort because the weight of the puller is not borne by the user's arms but by the support arm of the carrier. The weight of the puller and the support arm is distributed over the vest to the user's shoulders and pelvis, preventing fatigue of the arm muscles.
    Page 5 6/27 Μ 1678 • Better, easier alignment of the peel-off element. Since the user's upper body is always almost vertical even when in motion, the handle of the puller is always almost vertical. This results in only minor deviations of the peel strip from the horizontal position and the actuator between the handle and peel strip only has to compensate for smaller angular deviations. • slowing down the vertical movement. By carrying out the support arm as a parallel-static articulated arm is achieved that the puller follows vertical movements of the user only slowly. This results in lower demands on the speed of the actuator for the change in length of the stem or the telescopic rod. For the design of the sensor on the stem there are several possibilities, for example, sensors for inertial navigation (inertial navigation) can be used. An example of this is inertial measurement units (IMU) in which three orthogonally arranged acceleration sensors (also referred to as translation sensors) and three orthogonally arranged yaw rate sensors (also referred to as gyroscopic sensors) are arranged on a platform (inertial platform). As rotation rate sensors and optical gyroscope (ring laser gyro or fiber optic gyroscope) can be used. Particularly advantageous because of their small size and their low power consumption are micro-electro-mechanical systems (MEMS), which allow the integration of microchip inertial sensors.
    For example, the sensor on the stripper may be made up of one or more electronic inclinometers, e.g. electronic spirit levels. Of course, the same or similar inertial sensors as in the sensor at the top of the stem can be used.
    Page 6 7/27 Μ 1678
    Of course, it is also possible to provide only one Inertialsensor (inertia-le measuring unit) in the Abziehleiste, which serves to control / regulation of both actuators, ie for the actuator to change the angular position between stem and Abziehleiste and for the actuator for changing the Length of the stem.
    It is also possible to provide for the horizontal alignment two at an angle of 90 ° to each other arranged electric spirit levels and use only for detecting the vertical movement of an inertial sensor.
    This results in a system in which there are absolute measured values for the horizontal orientation and relative for the adjustment of the vertical position. If absolute measurement data are to be recorded for the vertical position as well, then another measuring system must be used instead of the inertial sensor.
    Such measurement systems may be, for example, optical using one or more light sources such as light emitting diodes, laser diodes, lasers or rotary lasers, and one or more photosensitive sensors (e.g., photodiode, photodetector).
    Time-of-flight measurements (e.g., by ultrasound or light beam), e.g. Runtime measurement to the ceiling of a room by a transmitter / receiver arrangement at the top of the stem and detecting the deviation from the vertical of the stem by a arranged in this electronic spirit level. Of course, such an implementation works only in rooms with a horizontal, level ceiling.
    Systems are also conceivable in which the light source is arranged on the handle or on the stripper and the sensor or sensors for detecting the spatial position of the light source are arranged in space. Conversely, of course, the light source in the
    Page 7 8/27 Μ 1678
    Be arranged space and the light-sensitive sensor on the stem or the Abziehleiste the Abziehelements be arranged.
    These prior art measuring devices described herein are illustrative of the invention and may, of course, be combined in any manner well-known to those skilled in the art, or by other prior art known measuring devices for detecting the spatial location and position of a device serve, be replaced or supplemented.
    The invention is illustrated by means of drawings:

    Fig. 3: shows the preferred embodiment of the inventive Shen Abziehelements using a support device and representation of a possible sensor principle.

    The subject invention is characterized firstly by the fact that the spatial orientation of the peel strip 1 is detected. More specifically, it is sufficient that its horizontal orientation and the height h on which it is located with respect to a reference plane are detected by sensors. Second, by having one or more actuators 5, which serve to control and / or regulate the horizontal orientation and the height h of the puller strip 1.
    Fig. 2 shows the peel strip 1 in a first and a second position. The spatial position and orientation of the peel strip
    1 can be detected in a reference / world coordinate system (x, y, z) and / or in a relative coordinate system (χ ', γ', ζ ') or (x' ', y'). ', z' '). The x-y plane of the world coordinate system is usually horizontal and the z axis is vertical. The x-y plane can be real, eg. the floor or the ceiling of a room can be given by means (eg projection by a rotating laser 6.2.1) or purely virtual. The plane x'-y 'is formed by the underside of the peel strip 1, that is, the surface which rests on the ground during Ni-vellierens. During leveling, the plane x'-y 'always aligns parallel to the x-y plane. The x-y plane also serves as a horizontal reference plane for controlling the height h of the pull bar 1. Therefore, it is sufficient to set a reference plane before leveling. Since this is usually aligned horizontally, it is sufficient to detect the inclination of the plane x'-y 'and to control or regulate so that it is zero, that is, the plane x'-y' is also horizontal.
    If the reference plane x-y real is present, the height difference between this plane and the plane x'-y 'is measured and kept constant by the controller. If the height h is to be relatively detected, e.g. by an inertial sensor, the plane x-y can be virtually specified. This can be done by keeping the peel strip at the desired height and referencing the plane x'-y 'thus present as a reference plane x-y. During leveling, the height difference between the two levels is kept at zero.
    In Fig. 1 shows a possible implementation of the peeling element is shown. The peel strip 1 and the stem 3 are connected to each other via a joint 2, which has at least 2 degrees of freedom. For example, it may be formed as a ball joint or as two successively arranged at an angle of 90 ° to each other pivot joints. This allows the horizontal
    Page 9 10/27 Μ 1678 irrespective of the vertical orientation of the handle 3, or keep it level. In order to change the height h of the peel strip 1, the stem 3 is made variable in its length. In Fig. 1, the stem 3 is designed as a telescopic tube, wherein the lower part of the stem 3 has a smaller diameter and in the upper part of the stem 3, which has a larger diameter, is added. In the upper part of the stem 3 is a linear drive, which moves the lower part of the stem 3 from the upper part of the stem 3 out or into it. For this relative movement of the two handle parts causes a change in height of the puller strip 1, the upper part of the stem must be kept. The support must oppose to the movement of the upper part of the stem 3 a force (counterforce) which is higher than the force which is applied to move the Abziehleiste 1 together with the lower part of the stem 3 vertically to the leveling surface. The holding of the upper part of the stem 3 can be done by a person, or preferably by a carrying device. If the peeling element is held directly by a person, this has the disadvantage that the weight of the peeling element acts on the arms of the person. In addition to the weight force, the person must also apply the opposing force, which can alternately act with the force of gravity.
    Fig. 3 shows the advantageous holding the Abziehelements on a support device. The support device consists of a support arm 8 and a harness 9. The harness serves to transmit the weight of the Abziehelements and the support arm 8 to the body of a person. The harness 9 may be attached in the form of a vest on the upper body, or in the hip or thigh area. The support arm 8 is formed in the example of FIG. 3 as a parallel-static articulated arm. In the middle vertically pivoting part of the articulated arm, a spring is attached, the bias of the weight of the From page 10 11/27 Μ 1678 ziehelements corresponds. The spring force thus counteracts the weight. Thus, the pull-off element can be operated by the person to whom the carrying harness 9 is fastened, with the arms, without having to hold the pull-off element.
    The support arm 8 is connected to the harness 9 via a hinge with the harness 9. The axis of rotation of the joint is vertical, so that the Abziehelement can pivot relative to the person in the horizontal plane. Another hinge is located at the front end of the support arm 8, where the connecting element 7 engages in this. The axis of rotation is again vertically aligned, so that the Abziehelement is pivotable about this axis in the horizontal plane. If this hinge is close to the stem 3, or the stem 3 passes through the hinge through the Abziehelement can be quasi or exactly rotated about the vertical axis of the stem 3. The same is achieved if on the side of the connecting element 7, in which the stem 3 is received, a rotary joint with a vertical axis of rotation is present.
    FIG. 3 shows a sensor principle in which a rotational laser 6.2.1 mounted in the room is used. The rotary laser 6.2.1 is preferably carried out horizontally self-leveling. The method steps for performing the leveling in this case are as follows: - Setting up the rotary laser 6.2.1 at any point in space, at any or measured height. This can be a tripod with a tripod serve. - Self-leveling of the rotary laser 6.2.1 to the horizontal. - Creating the harness 9 with support arm 8 and peel 1.
    Page 11 12/27 Μ 1678 - Defining the height difference which the peel strip 1 should assume for the plane x-y given by the rotation laser 6.2.1. - At any height of the laser, the peel bar can be kept to the desired height h and the height difference to the x-y level can be set as the reference value. - With measured height of the laser, an absolute value for the height difference can be specified. For example, the height difference should be exactly 100cm. - Passing the room under handling (pivot / turn the stripper 1 in the horizontal plane) of the Abziehelements. - During the Abschreitens the puller bar 1 through the
    Actuators 5 held in the horizontal and by the actuator 4, the height difference of the puller bar 1 to the reference plane, which is spanned by the rotating laser is kept constant. The actuators 5 are controlled or processed by processing the data / signals of the sensor or sensors 6.1. The actuator 4 is controlled or processed by processing the data / signals of the sensor or sensors 6.2. As sensors 6.1, for example, two electronic spirit levels arranged at an angle of 90 ° to each other, or an inertial measuring unit can be used. As sensor 6.2, an optical receiver is used, which is able to determine the height difference to the plane defined by the rotation laser 6.2.1 reference plane x-y.
    In Fig. 4, the principle is shown as the Abziehleiste 1 is held in the horizontal when a joint 2 between Abziehleiste 1 and 3 stem is present. The joint 2 is formed in this case by two hinges, each of these hinges is adjustable with a motor. The motor can be designed as a direct drive, servo or stepper motor. It is important that a highly dynamic drive is used to perform high-frequency, smallest correction movements. To
    Page 12 13/27 Μ 1678 control of the motors the signal of the sensors 6.1 is processed. For example, these are electronic spirit levels. One of these spirit levels is arranged in the direction of the x-axis, the other in the direction of the y-axis (not shown, runs perpendicular to the paper plane). If the spirit level, which is arranged in the direction of the x-axis, detects a deviation from the horizontal, the motor whose axis of rotation runs in the y-direction is controlled in order to compensate for this deviation. If the spirit level, which is arranged in the direction of the y-axis, detects a deviation from the horizontal, the motor, whose axis of rotation runs in the x-direction, is controlled in order to compensate for this deviation. Of course, in turn, other sensors 6.1 can be used to detect these deviations.
    The sensor 6.2 for the height detection is mounted in this case in the pull bar 1. This may be an inertial sensor, or an optical or acoustic receiver which is capable of determining its position with respect to a reference system. By processing the signals of this sensor 6.2, the actuator 4 is controlled to keep the height h of the stripper 1 constant. The actuator 4 can be designed as a linear drive, linear motor, rack drive, toothed belt drive or the like. Important is in turn a high dynamics of the drive.
    Fig. 5 shows another concept of the subject invention. In this case, it is necessary that the Abziehelement by a support device (support arm on a vest, a robot or on a mounted support) is held. Here, the stem 3 is not connected via a hinge 2 with the peeling element 1, but fixedly attached at an angle of 90 ° to this. In order to keep the puller in a horizontal position, it is therefore necessary to keep the handle 3 in a vertical position. This results in a simplification in terms of the sensor. In order to keep the stem in vertical position, the connecting element
    Page 13 14/27 Μ 1678 ment 7 articulated. In the example, this articulated connection is formed by a joint 7.1 and a joint 7.2. Analog to the joint 2, which could change the orientation of the puller strip 1 with respect to the horizontal or kept constant, can be changed by the joints 7.1 and 7.2, the orientation of the stem 3 with respect to the vertical or kept constant. The joints 7.1 and 7.2 can in turn be designed as a ball joint. The joints 7.1 and 7.2 are automatically adjustable by suitable actuators.
    In Fig. 5, a variant is shown in addition, in which the handle 3 is not designed as a telescopic rod. The actuator 4 is here part of the connecting element 7 and serves to the stem 3 relative to the connecting element 7 to move up and down. It is also conceivable that the actuator 4 engages the support arm 8. With respect to the height then the connecting element 7 is rigidly connected to the stem 3. The change in height of the Abziehleiste 1 is then carried out by changing the position of the connecting element 7 relative to the support arm 8, by adjusting the height of the support arm 8 itself or by changing the height of the support arm 8 with respect to the harness 9. The sensor 6.1 is mounted in the example of FIG. 5 on the connecting element 7 while the sensor 6.2 is attached to the handle. It is also conceivable to attach both sensors 6 to the connecting element. The sensor 6.1 is in this case rod-shaped and protrudes from the end of the stem 3 vertically upwards. On its vertical surface, photodetectors are arranged so that they detect incident light of the rotary laser 6.2.1 from all directions and over the entire length range of the rod. A simple sensor arrangement can be achieved if the rod is formed as a dimensionally stable optical waveguide which has a fluorescent layer and thus converts incident light into long-wave light and passes it on to its ends, wherein a photodetector is attached to one or both ends. If the rotary laser 6.2.1 is above the head height of the
    Page 14 15/27 Μ 1678 person is reached and the staff also projects beyond the person, it is achieved that the person does not unintentionally interrupt the beam path from the rotating laser 6.2.1 to the sensor 6.2 while the space is being traversed.
    It is clear from the description of the figures that various design variants of the sensors, actuators, the pull-off element, the connecting element and the joints can be used. It is understood that the described embodiments of the sensors, actuators, the Abziehelements, the connecting element and the joints can be combined in any way to obtain a device according to the invention.
