Definitions
- the invention relates to a work table with a particular height-adjustable frame, the adjustment of which at least one electric motor is provided with a control device.
- the invention is therefore based on the object, a work table of the type described in such a way that obstacles that reach the trajectory of the work table or drive parts, are detected in a simple manner can shut down the table drive before any damage or injury occurs.
- the invention solves the problem set by the fact that the control device connected to a sensor for the engine load reverses the direction of rotation of the electric motor as a function of the determined magnitude and / or change of the engine load and switches off after a reverse rotation caused thereby.
- any obstacle entering the path of movement of a work table or one of its driving parts increases the engine load, the occurrence of an obstacle can be detected by appropriate monitoring of the engine load, regardless of the local location of the obstacle.
- only one encoder for the load of the engine or the motors needs to be arranged and a control device to be acted upon by the determined engine loads to reposition the direction of rotation of the drive when appropriate changes in engine load or exceeding a predetermined load limit and the engine or to stop the motors after a corresponding reset path.
- the resetting of the drive offers over a mere shutdown of the engines the advantage that the obstacle is released after starting again and therefore can be removed unhindered from the adjustment of the work table.
- the engine load can be determined in different ways, for example via the effective torque which can be detected via a provided in the course of the engine support pressure sensor. Particularly simple design conditions, however, arise when the encoder for the engine load consists of a measuring device for the motor current, which indeed changes with the engine load.
- the illustrated embodiment shows a work table with a table top 1, which is supported by a frame 2, the telescopic legs 3 for height adjustment of the table top 1 has.
- These telescopic legs 3 are adjustable by means of electric motors 4, which drive with a rack 5 meshing gears 6, when the electric motors 4 are controlled via a control device 7.
- an input unit 8 which can also be wirelessly connected to the control device 7 in conjunction and has a conventional input field 9 for operating the work table.
- the engine load is detected by encoder 10 and forwarded to the controller 7, so that due to corresponding changes in load, an intervention in the engine control can be made.
- the arrangement is made such that the electric motors 4 are not only stopped, but also reversed in their direction of rotation to reset the table top 1 to release the obstacle.
- a timer 11 controlled which specifies a preferably adjustable period of time for the opposite motor operation.
- the encoders 10 for the engine load are formed in the embodiment as a measuring device 12 for the respective motor current and turned on in the supply lines 13 between the motors 4 and a power source 14, which may be in the form of, for example, a power supply or a battery.
- a measuring device 12 for the respective motor current is formed in the embodiment as a measuring device 12 for the respective motor current and turned on in the supply lines 13 between the motors 4 and a power source 14, which may be in the form of, for example, a power supply or a battery.
