Definitions

  • the invention relates to a device for limit switching of a motor drive device of a winding shaft of a roller shutter according to the preamble of patent claim 1.
  • Such a device is for example from the DE 197 06 209 A1 known.
  • a final shutdown of a motor drive device of a winding shaft of a roller shutter is made possible by a sensor for detecting torque changes as a result of load change processes acting on the winding shaft or the drive device while the roller shutter curtain is being lowered.
  • the sensor responds to such load change processes that occur when the roller shutter curtain touches an obstacle or is completely closed when it moves down.
  • a drive shutdown is also known in which the microswitches used there are hidden outside a range around the end positions. In the end positions, the drive is switched off via a torque. However, it is necessary that these end positions have to be set precisely beforehand.
  • a device for switching off the drive of a motor of electrically operated shutters, roller doors, awnings and the like by means of at least one switching element is known.
  • the switching element In its end position of the roller shutter curtain, the switching element interrupts the motor circuit when a switch is actuated.
  • the switching element acts against the action of a spring which is adjustable in its restoring force on a switch closing the circuit of the motor.
  • the device according to the invention for the final shutdown of a motor drive device of a winding shaft of a roller shutter has a sensor for detecting torque changes as a result of loads or load change processes acting on the winding shaft or the drive device.
  • the sensor is designed as a mechanical switching element which has two interacting components, the relative angular position of which can be changed with respect to a common longitudinal axis. Different switching states of the switching element are dependent on the relative angular position of the two components represented.
  • the switching element has two switches, the one switch being operable by the one component in a first angular setting of the two components with respect to one another and thereby causing the motor drive device to be switched off in a first end position of a roller shutter curtain while the other switch in a second angular setting of the two components with respect to one another by means of which one component can be actuated and thereby brings about an end shutdown of the motor drive device in a second end position of the roller shutter curtain.
  • the configuration according to the invention results in multiple advantages over the devices known from the prior art. On the one hand, it is no longer necessary to set the end positions after assembly of the device according to the invention.
  • the end position detection is carried out automatically without having to be set or programmed beforehand. This also results in an automatic curtain length compensation by the device according to the invention after it has been installed, without the curtain length having to be set beforehand by a mechanic.
  • the device according to the invention also provides obstacle detection both when moving down and when moving up the roller shutter curtain of a roller shutter.
  • the short and compact design of the device according to the invention is also advantageous, so that only minimal installation space is required for assembly.
  • the relative angular position of the two components of the sensor designed as a mechanical switching element can be changed within an angular range ⁇ ⁇ .
  • the two components can be rotated relative to each other about the common longitudinal axis by ⁇ 5 ° to ⁇ 30 °, preferably by ⁇ 15 ° in both directions.
  • exactly one stop means is provided, the one component striking the stop means when the one which is movable by the motor drive device Roller shutter curtain reaches its end position in which it is wound up.
  • the configuration of the device according to the invention with such a stop means ensures that the two components only rotate relative to one another by the desired angular range.
  • the one component is arranged to be stationary after assembly of the device, while the other component is rotatably held in the first component.
  • the stop means is arranged under spring force, the spring load being formed by a spring element arranged in a receptacle, which is particularly preferably designed as a compression spring, in particular as a spiral spring.
  • a spring element can be further tensioned by the one component, which is rotatably held on the other component after the assembly of the device, possibly beyond a preload.
  • tensioning of the spring by the one component occurs in particular when the roller shutter curtain reaches the end position in which it is wound, so that the second switch of the switching element can then be actuated by an actuating element arranged on the component.
  • the twist of the two components of the switching element relative to one another is generally not equal to 0 °, which, however, is not sufficient to actuate the second switch of the switching element.
  • two stop means are alternatively provided, one component striking one of the stop means when the roller shutter curtain movable by the motor drive device reaches one of its two end positions.
  • the configuration of the device according to the invention with such slings means that the two components only rotate relative to one another by the desired angular range.
  • the one component is arranged to be stationary after assembly of the device, while the other component is rotatably held in the first component.
  • the stop means are arranged against one another under spring force, the spring load being formed by a spring element arranged in a receptacle, which is particularly preferably designed as a compression spring, in particular as a spiral spring.
  • a spring element can be further tensioned by the one component, which is rotatably held on the other component after the assembly of the device, possibly beyond a preload.
  • tensioning of the spring by one component occurs in particular upon reaching the end positions of the roller shutter curtain, so that one of the two switches of the switching element can then be actuated by an actuating element arranged on the component.
  • the twisting of the two components of the switching element relative to one another is generally not equal to 0 °, which is, however, not sufficient to actuate the switches of the switching element.
  • a twisting of the two components against each other which is sufficient to actuate the switch of the switching element, only takes place when the roller shutter curtain reaches the end positions or when the roller shutter curtain hits an obstacle while the roller shutter curtain is being lowered or pulled up.
  • the corresponding switches which are preferably designed as microswitches, are actuated when the maximum rotation of the two components of the switching element relative to one another is reached. The actuation also takes place only when the spring element is tensioned by the one component. By actuating the switch, the voltage supply to the motor drive device is interrupted and the drive is stopped.
  • the spring element is dimensioned or equipped with such a spring constant that the components of the switching element are only rotated by the maximum angle ⁇ from a predetermined torque, for example a torque of 4 to 5 Nm. This avoids that even minor obstacles or the friction in the system cause the motor drive device to stop or stop.
  • the torque resulting from the weight of the roller shutter curtain must not exceed this predetermined torque, so that the motor drive device is not already switched by the weight of the roller shutter curtain and thus it would no longer be possible to pull up the roller shutter curtain.
  • the spring element is advantageously arranged in a housing consisting of at least two elements, which in turn is in the receptacle for the spring element can be arranged.
  • This embodiment of the invention is therefore advantageous since the spring element is inserted into the device according to the invention under pretension and a compression spring, for example designed as a spiral spring, can be placed relatively difficultly while maintaining the spring pretension in the receptacle of the device according to the invention.
  • the placement of such a spring element in a housing makes it possible to easily insert the housing with the spring held therein under tension into the receptacle of the device according to the invention.
  • the at least two elements of the housing can be displaced relative to one another in such a way that the spring element can be deformed against its spring force by the one component of the switching element.
  • This configuration of the invention ensures in a simple manner that the spring element arranged in the housing can be mounted in a simple manner in the device according to the invention and at the same time maintains its deformability, which is necessary for actuating the switches of the switching element.
  • a spring constant of the spring element is adapted to the roller shutter curtain in such a way that its weight is too low to actuate the switches of the switching element.
  • the motor drive device is provided with a stator, the windings of which are designed such that there is no magnetic saturation of an iron core of the stator during operation of the device.
  • a winding of the stator is also known as a soft winding and is characterized in that a significantly larger number of turns is used than is actually necessary for operating the device.
  • a wire with a small wire diameter is used as the winding wire, so that - in relation to the usual standard size - this results in a reduction in the torque.
  • the present invention also relates to a tubular drive with a previously described device and a motor drive device.
  • the present invention also relates to a roller shutter with such a tubular drive and a winding shaft connected to the tubular drive, to which a roller shutter armor can be arranged.
  • a tubular drive 21 is shown, which is equipped with a device according to the invention for limit switching of a motor drive device 1 and a winding shaft 9 of a roller shutter.
  • the tubular drive 21 has a switching element 10 with components 2 and 3.
  • the components 2 and 3 of the switching element 10 can be rotated relative to one another about a longitudinal axis 11 by an angle ⁇ a, which in the following examples is approximately 15 °.
  • FIG. 1 An embodiment of a switching element 10 is in the Figure 2 shown in three different switching positions.
  • the two components 2 and 3 are arranged concentrically about the longitudinal axis 11, the component 2 designed as a connection part being rotatable within the component 3 designed as a switch housing relative to the component 3 by the angle ⁇ ⁇ .
  • the switching element 10 has a receptacle 16 in which a spring element 5, in the present case designed as a spiral spring 18, is arranged.
  • the spring element 5 is held under prestress in the receptacle 16.
  • the middle representation of the Figure 2 shows the switching element 10 in a zero position, in which the component 2 is not rotated relative to the component 3 of the switching element 10.
  • the angle of rotation ⁇ has the value 0 °.
  • Component 2, which is rotatable relative to component 3 of switching element 10, is additionally equipped with an actuating element 22 with which two switches 4, 13 of switching element 10 can be actuated.
  • a torque must act on the component 2 which is sufficiently large so that the component 2 is able to counteract the spring element 5 arranged in the receptacle 16 and designed as a spiral spring 18 to compress its spring force.
  • the tubular drive is provided with a winding shaft 9, on which a roller shutter armor 7 is arranged at one end by means of connecting elements 6 designed as shaft connectors.
  • a stop element 8 is arranged at the other end of the roller shutter curtain 7.
  • the spring element 5 is held in the receptacle 16 in such a way that stop means 14 and 15 for the component 2 are formed at the ends of the spring element 5.
  • the roller shutter curtain 7 is either in a closing or an opening movement or in a position, the switching element 10 corresponding to the central representation of FIG Figure 2 remains in an angular position in which it is not operated.
  • the ends of component 2 lie against stop means 14 and 15. However, no force or torque is exerted on the spring element 5 by the component 2, so that the spring element 5 remains within the receptacle 16 in its prestressed state.
  • the roller shutter curtain 7 is now from the middle representation of the Figure 3 lowered downwards, the roller shutter curtain 7 comes to rest with its lower end or with the stop element 8 arranged thereon on a lower stop 23.
  • the component 2 of the switching element 10 is pressed against the stop means 14, so that the spring element 5 within the receptacle 16 of the switching element 10 is further compressed.
  • This deformation of the spring element 5 continues until the actuating element 22 of the component 3 actuates the switch 4 or 13, which is preferably designed as a microswitch. By actuating this switch 4 or 13, the motor drive device 1 is switched off, so that the drive device 1 no longer generates any torque.
  • roller shutter armor 7 which in the right representation of the Figure 3 covers an opening or a window 12, now opened by means of the motor drive device 1, the roller shutter curtain 7 moves until it hits a stop 24 with its stop element 8 at the other end of the opening or the window 12. This avoids a further movement of the roller shutter curtain 7.
  • the drive device 1 has not yet received a stop signal, it continues to run.
  • the component 2 is rotated in the other direction within the component 3 of the switching element 10.
  • the component 2 strikes the other stop means 15, so that when the component 2 is rotated further, the spring element 5 is compressed. This compression of the spring continues until the actuating element 22 of the component 2 now actuates the switch 4 or 13, which is also designed as a microswitch.
  • the motor drive device 1 is stopped, so that the motor drive device 1 no longer acts on the switching element 10.
  • the motor drive device 1 no longer generates torque, but the moment existing at the moment the drive was switched off continues to act. This prevents driving in the same direction, and driving is only possible in the other direction.
  • FIG. 4 A further exemplary embodiment of a device according to the invention is now shown. This differs from the embodiment of FIG Figure 2 in that the component 2 does not rest against the stop means 14 at one end in its position in which the switching element 10 is not actuated. Rather, a free space X is formed there between the component 2 and the stop means 14. It is of course possible here that this free space X is formed on the stop means 15 and not, as in FIG Figure 4 shown on the lifting means 14. However, the mode of operation is exactly the same in both cases as in the device according to FIG Figure 2 , However, the spring element 5 within the receptacle 16 is not deformed or compressed during the closing process, but remains under its pretension in the receptacle 16.
  • the switching element 10 then takes when the end of the roller shutter armor 7 provided with the stop element 8 touches down on the bottom stop 23, the position in the right-hand illustration of FIG Figure 4 on.
  • Switch 4 or 13 is also actuated by actuating element 22 of component 3.
  • the component 2 does not have to overcome the spring force of the spring element 5 and thereby deform the spring element.
  • the motor drive device 1 is provided with a stator, not shown here, the windings of which are designed such that no magnetic saturation of the iron core of the stator occurs during the operation of the device.
  • a stator not shown here, the windings of which are designed such that no magnetic saturation of the iron core of the stator occurs during the operation of the device.
  • Such a "softly wound” stator ensures that the drive device 1 switches off gently as soon as the roller shutter curtain is stopped by the stops 23 or 24.
  • the softly wound stator causes the speed of the drive device to decrease rapidly when the end position is reached and the stop is therefore approached gently.
  • the spring element 5 designed as a spiral spring 18 is arranged in a housing 17.
  • the housing 17 consists of two elements 19 and 20, which can be moved into one another.
  • the element 19 has projections 25 and 26, between which receptacles 31 and 32 are formed. These receptacles 31 and 32 serve to receive corresponding projections 27 and 28 of the element 20.
  • 20 receptacles 29 and 30 for receiving the projections 25 and 26 of the element 19 are also formed between the projections 27 and 28 of the element 19.
  • the spring element 5 designed as a spiral spring 18 is inserted into the element 20 for assembly, as shown in FIG Figure 5 is shown.
  • the element 19 is then guided with its projections 31 and 32 into the receptacles 29 and 30 of the element 20.
  • the projections 27 and 28 of the element 20 are guided into the receptacles 31 and 32 of the element 19 of the housing 17.
  • the housing 17 takes the in Figure 6 shown form, in which the spring element 5 is arranged in the housing 17.
  • the spring element 5 can then be preloaded within the housing 17 while overcoming the spring force and, in the preloaded state, can be installed in a receptacle 16 of a device according to the invention, as shown in FIG Figure 8 is shown as an example. Elements 19 and 20 are tilted against each other so that one end can be placed in the receptacle 16. Pressing the housing 17 completely pushes the housing 17 into the receptacle 16. The spring element 5 is biased between the elements 19 and 20.
  • Figure 9 finally shows the position of the housing 17 after it has been introduced into the receptacle 16 of the device, so that the spring element 5 is held in the receptacle 16 under pretension, the stop means 14 and 15 being located on the end faces of the elements 19 and 20 designed as spring caps ,
