Definitions

  • the invention relates to a method and a device for securing gates with a light grid, which has a plurality of protective beams in protective beam positions.
  • the light grid is arranged so that its monitoring surface at least partially coincides with a plane of movement of the gate to be protected.
  • the protective beams of the light grid are arranged transversely to a closing movement direction of the gate to be protected.
  • Each of the protective beams forms an active state in which the switching state of this protective beam is evaluated for object detection.
  • each of the protective beams forms a passive state, in which the switching state of this protective beam is determined, but is not evaluated for object detection.
  • the safety device off EP 2 374 985 A2 has a light curtain with a number of light emitters, light receivers will only capture foreign objects.
  • a security system for securing a moving, guided movement element against unwanted collision is known.
  • the movement element has shutdown means which, upon detection of a shutdown signal coming from the movement element, convert at least a part of the object detection device into the starting state.
  • These shut-off means comprise a transmitting device for a shutdown signal, which either sits directly on the moving element or which is tuned to a separate optical reflector on the moving element in such a way that by a receiver switching off only in a predefined range of movement of the reflector on the moving element a signal of the transmitting organ can be received.
  • an object detection device is assigned a starting state in the case of an approaching movement element, in which an object or movement element does not trigger a safety mode. A security mode is only triggered if an object not belonging to the movement element is recognized by the object detection device.
  • This securing system of a moving, guided movement element has the disadvantage that optical devices, be it a reflector for electromagnetic radiation or a transmitting element for a switch-off signal, are to be arranged on the moving element and thus at gates on the gate. At least for a shut-off in the form of a transmitting organ on or on the gate should be provided according to entrained connecting lines, which brings a considerable technical effort and an additional risk of wear, for example, for the co-moving connecting lines with it.
  • the receivers of the associated, a shutdown signal generating sensors are arranged along the frame of the moving element, so that the arranged on the moving element transmitting organ receives the transversely to the direction of movement of the door lying optical sensors, so the technical effort is still high.
  • the optical receiving grid spanned by the sensors and its security function depends on the components arranged on the moving element or the gate. Although no electric supply is required for a separate optical reflector, the technical and financial outlay for an optical beam following the moving element with the reflector and the orientation towards the optical reflector moving with the gate are nevertheless considerable.
  • EP 1 841 942 B1 a device for securing a driven movement element against unwanted collision with a lying on a predetermined path of movement in the direction of movement of the moving element object is known.
  • a light grid of light barriers which are arranged transversely to the direction of movement of the moving element, fixedly arranged on the sides of the door, so that can be dispensed with active and passive components on the door itself.
  • the same disadvantages also have the safety device for motorized doors according to EP 0 902 157 A2 in which a safety circuit is provided, with which the closing movement of the gate is stopped when an obstacle in the trajectory of the gate is detected.
  • the radiation protection is arranged such that the beam surface defined by the beams has at least one line in common with the movement surface swept by the leading edge and that the self-sufficient safety device has a beam condition control device which controls the beams as a function of the position and movement of the beam Assigns different activation states to gates.
  • an object of the invention can be considered to overcome the disadvantages of the prior art and to provide a method and apparatus for securing gates by means of a light grid, which allows increased distances between the protective beam positions and thus a coarser grid of the protective beams while undiminished security against faulty circuits.
  • each protective beam position emits in addition to the protective beam a leading secondary protection beam and a trailing secondary protection beam and that the protective beam position is made passive in the following plausibility condition, namely, if a preceding protective beam position is passive, and the protective beam position for the first time is switched with its protective beam and switch at least the trailing protective beam of the protective beam position and immediately following in closing closing leading secondary protection beam of the subsequent protective beam position in a subsequent, adapted to the closing movement of the gate time interval, and that the closing movement of the door stops when an object by at least an actively placed protective beam and / or at least one active auxiliary protection beam is detected.
  • each protective beam position has a leading secondary protection beam and a trailing secondary protection beam in addition to the protective beam and that the control and evaluation device is set up to passivate a protective beam position in the following plausibility condition if a preceding protective beam position is made passive and the protective beam of the protective beam position is switched for the first time and at least the trailing protective beam of the protective steel position and immediately following in closing movement leading secondary protection beam of the subsequent protective beam position in a subsequent, adapted to the closing movement of the gate time interval, and that the closing movement of the gate stops when a Object is detected by at least one active protection beam and / or at least one actively set secondary protection beam.
  • this may mean that at least one of the active protective beams and / or secondary protection beams switches.
  • These may be all protective beams and / or secondary protection beams whose switching state is not in the plausibility condition as well as the latter protective beams and / or secondary protective beams, as far as their switching takes place outside of the time intervals relevant for the plausibility condition.
  • the door to be monitored can be wholly or partially opened when an object is detected by at least one actively placed protective beam and / or at least one actively set secondary protection beam.
  • An advantage of the method according to the invention is that, by the formation and provision of a leading secondary protection beam and a trailing auxiliary protection beam with respect to a parallel to the closing edge of the goal-oriented protective beam in each protective beam position, the monitoring of the closing edge from beginning to end despite increased distances between the parallel Protective beam positions can be improved.
  • the protective beams and secondary protection beams are successively displaced from an active switching state into a passive switching state during the closing process of the gate.
  • a faulty object in the monitoring area of the light grid which is not yet closed by the gate can trigger a rapid stop of the closing operation, while the protective beams and secondary protection beams which are already covered by the side edge of the closing gate have entered a passive state in which the switching state is both of the parallel protective beam as well as the leading secondary protection beam and the trailing secondary protection beam is determined, but is not evaluated for object detection.
  • a particular advantage of the method according to the invention is that the light grid can be arranged in the door frame itself and accordingly is very space-saving.
  • the inventive method can also be carried out with existing light grids and it can then, even at high closing speeds of the door to 4 m / s, for example, the monitoring protection to be maintained until shortly before the ground. For example, this is possible up to a distance of 50 mm above the ground.
  • the monitoring phase of the door can also begin in an intermediate position, for example in a half-open position of the gate.
  • leading or trailing auxiliary protection beams take over the monitoring of the closing movement of the door in an advantageous manner and, in cooperation with the plausibility condition, release the respective switching from the active state to the passive state in the individual protective beam positions.
  • parallel protective beams are emitted in the individual protective beam positions, but additionally generated with respect to the parallel protection beam tilted secondary protection beams, the leading secondary protection beam from its protective beam position with a previous receiving sensor or previous optical reflector cooperates and the trailing Crowschutzstrahl starting from its protective beam position with a subsequent optical sensor or reflector cooperates.
  • the corresponding protective beam position is made passive, namely when a preceding protective beam position is detected and passive and the corresponding protective beam position is switched with its protective beam for the first time and at least in the closing movement immediately following leading protection beam of the following protective beam position in a following, adjusted to the closing movement of the gate time interval switches.
  • the time interval adapted to the closing movement of the gate can be an extremely short time window since this is merely a question of Compensate for unevenness in the closing edge of the door; because the leading secondary protection beam of the following protective beam position is available immediately when passing the previous sensor or reflector position.
  • the short time window for the time interval during the changeover of a protective beam position from an active state to a passive state can be determined by a simple on-site learning journey for the respective port.
  • the parallel protective beams of the light grid are arranged equidistantly, while in the parallel aligned protective beams of the document EP 0 902 157 A2 known safety device for motor-driven doors, the distance between the parallel protective beams in the end of the closing process must be significantly reduced to ensure adequate safety.
  • the protective beams may also be advantageous not to equidistant the protective beams, but rather to arrange them somewhat closer in the vicinity of the floor area, for example.
  • the spatial resolution can be increased thereby. This is particularly important in the ground-near area, where typically can be disturbing objects, of importance.
  • the reliability of the hedge can also be increased if in addition to the considered trailing.
  • Supplementary protection beam of the protective beam position and the leading secondary protection beam of the subsequent protective beam positions, the switching within fixed time intervals of further, especially crossed, protective beams and / or secondary protection beams in the evaluation and the plausibility condition is taken into account.
  • the method according to the invention requires that at least one protective beam position is active. Different conditions may apply for the very first and last position.
  • leading secondary protective beams are tilted with respect to the parallel protective beams against the direction of the closing movement of the gate to be protected, while the trailing secondary protective beams are tilted in the direction of the closing movement of the gate to be protected with respect to the parallel protective beams run.
  • both the parallel protective beam and the associated leading and trailing secondary protection beams can be made passive.
  • the trailing secondary protection beam is of little importance, because in the case of the plausibility condition, the temporal behavior of a protective beam position and of an immediately following leading secondary protection beam of a subsequent protective beam position is important. Nevertheless, the trailing secondary protection beam of the passively placed protective beam position can increase the reliability of the inventive securing of the closing movement of a door.
  • a second aspect of the invention relates to a device for securing gates, in particular gates, with a light grid for monitoring the gate to be protected.
  • the light grid has a plurality of protective beams in protective beam positions and is arranged as follows.
  • the light grid coincides at least partially with a monitoring surface of a plane of movement of the gate to be protected.
  • the protective beams are transverse to a closing movement direction of the gate to be protected.
  • Each of the protective beams has an active state in which the switching state of this protective beam is evaluated for object detection.
  • Each of the protective beams also has a passive state in which the switching state of this protective beam is determined, but is not evaluated for object detection.
  • Each protective beam position has, in addition to the protective beam, a leading secondary protection beam and a trailing secondary protection beam.
  • the device has a control and evaluation device for controlling the light grid and for evaluating the measurement data supplied by the light grid.
  • the control and evaluation device is adapted to carry out a Passivstellen a protective beam position in the following plausibility condition when a preceding protective beam position is detected and passively set and the protective beam position is switched first and at least the immediately following in closing movement leading secondary protection beam of the following protective beam position in a subsequent the closing movement of the gate adjusted time interval switches.
  • a preferred embodiment is directed to the light grid which, for one embodiment of the apparatus, includes a plurality of infrared semiconductor lasers as light sources in the protective beam positions. Moreover, it is also possible to arrange an infrared semiconductor laser only in each protective beam position and to generate by prismatic beam splitting or fiber optic beam splitting the two secondary protection beams and the parallel protective beam by means of a single infrared semiconductor laser diode.
  • the invention over the known solutions has the advantage that the unprotected under the closing edge area is smaller and that the optical resolution is fundamentally improved by the leading and trailing secondary protection beams.
  • the present invention provides an improvement in reliability.
  • the solution known in the prior art which arranges optical elements on the moving gate, resulting in the present solution, both a lesser effort in terms of the assembly of additional parts to the closing edge of the moving door and a higher reliability, since the gate no supply lines or other electrical supply connections must be provided.
  • FIG. 1 shows a schematic diagram of a roll or folding door 50, which includes a device for securing a door leaf 20 with a closing edge 26 against a collision with an object while ensuring a high-speed movement of the door leaf 20 in the direction of arrow 24 a closing movement.
  • the door leaf 20 is thereby guided laterally in two guide profiles 42 and 44, which are held by an upper cross bar 46 at a distance, so that there is a clear width b and a clear height h a gate passage.
  • Door leaf segments of the door leaf 20 can be folded behind the transom 46, rolled up or stowed in bent horizontally oriented guide profiles when opening the gate.
  • a motor 14 is arranged, which has a switching relay 48 which is connected via a control line 18 with a control and evaluation device 40 in operative connection.
  • the motor 14 may be connected to a braking device 16, which in turn is connected via a mechanical connection 38 to the door leaf 20, so that in addition to a shutdown of the engine 14, an emergency braking operation for the door leaf 20 can be triggered.
  • the braking device 16 is connected via a further control line 18 'to the control and evaluation device 40.
  • a movement plane 22 of the door leaf 20 is monitored by a light grid 10 which has protective beam positions P3 to Pn in a monitoring area 12 which are in an active state in which the switching state of protective beams for an object detection is evaluated by the control and evaluation device 40.
  • protective beam positions P1 and P2 whose protective beams are placed in a passive state in which the switching state of the protective beams of the control and evaluation device 40 is indeed detected, but not evaluated for object detection, since in this monitoring range of the protective beam positions P1 and P2, the in the closing direction 24 moving door leaf 20 is located.
  • the control and evaluation device 40 is therefore connected via signal lines 34 with a plurality of protective beam positions P1 to Pn, which are arranged on or in the left guide profile 42 of the gate.
  • a signal line 34 operated in a multiplex method can also be used.
  • Each protective beam position P has three protective beams, namely a leading secondary protection beam V, a protective beam S aligned parallel to the closing edge 26 and a trailing secondary protection beam N.
  • receiving positions E1 to En can, for example, photodiodes or photoresistors whose measured values or switching states are supplied via further signal lines 36 of the control and evaluation device 40.
  • a signal line operated in a multiplex method can also be used.
  • FIG. 1 shows that the receiving stations E1 and E2 receive neither the parallel protection beams S1 and S2, nor the preceding subsidiary protection beams V1 and V2 or the trailing auxiliary protection beams N1 and N2, since a side edge of the door panel 20 covers the emitted protective beams of the protective beam positions P1 and P2.
  • the receiving stations E3 to En receive signals and pass measuring signals via the signal line 36 to the control and evaluation unit, as long as no object appears in the monitoring area 12 and the door leaf, which moves at high speed in the closing direction 24, the other protective beam positions P3 to Pn has not happened yet.
  • An object located within an active light beam grid 10 can be readily detected.
  • a plausibility condition must be met before another Protective beam position is placed in the passive state. This plausibility condition was discussed above, so that a repetition at this point is unnecessary.
  • FIG. 1 are the leading secondary protection beam V1, the parallel protective beam S1 and the trailing Mauschutzstrahl N1 already in the passive switching state, as the leading Mauschutzstrahl V2, the parallel protective beam S2 and the trailing Mauschutzstrahl N2.
  • the plausibility condition is now applied to the protective beams of the protective beam position P3, taking into account the trailing secondary protection beam N3 and the leading auxiliary protection beam V4 of the next protective beam position P4. If the plausibility condition is satisfied, the protective beams of the protective beam position P3 can pass into the passive state and the closing process can be continued without disturbance as the next one FIG. 2 shows.
  • FIG. 2 shows a schematic diagram of the secure door 50 according to FIG. 1 after passing another protective beam position P3.
  • the progressive closing of the door leaf 20 in the closing direction 24 was possible because the protective beam position P3 is switched for the first time with its parallel protective beam S and at least the immediately following in closing movement, leading secondary protection beam V4 of the subsequent protective beam position P4 in a subsequent adapted to the closing movement of the door time interval on.
  • This time interval can be extremely short, since it is not necessary to wait until the closing edge 26 has to reach the subsequent parallel protective beam, as required in the prior art, but when the closing edge 26 already reaches the leading secondary protection beam V4 after a short time interval.
  • this relatively short time interval can be determined by a one-time learning run of the door 50 and stored in the control and evaluation unit 40.
  • FIG. 3 shows a schematic diagram of the secure door 50 when detecting a small object 30 in the region of an active light grid 10 between the protective beam positions P3 to Pn. Like FIG. 3 shows, are interrupted by the small object 30 of the parallel protection beam S3 and the trailing Crowschutzstrahl N3, so that the in FIG. 1 shown control and evaluation unit 40 can cause opening of the door 50 against the closing movement direction 24 now in the direction of arrow 24 '.
  • the in FIG. 3 protective radiation positions of the protective beam positions P1 and P2 which are still in the passive state, are set back into the active state, because then there is again an optical connection to the receiving positions E1 and E2.
  • FIG. 4 shows a schematic diagram of the safe gate 50 when detecting a small-volume object 30 in different positions 30, 30 ', 30 "and 30'” in the region of the active light grid with the protective beam positions P3 to Pn. While, as in FIG. 3 3, the small object 30 interrupts the parallel protective beam S3 and the trailing protective beam N3 of the protective beam position P3, a small object 30 'would interrupt the trailing secondary protective beam N3 and the leading secondary protective beam V4 of the subsequent protective beam position P4.
  • FIG. 5 shows a schematic diagram of the secure door 50 when detecting a large object 32 within the active light grid 10 with the protective beam positions P3 to Pn. Since this object 32 is so large that it covers both the next parallel protective beam S3 for the first time and to the trailing Crowschutzstrahl N3 and the leading secondary protection beam V4 of the subsequent protective beam position P4 interrupts and thus the short time interval has also met, an object 32 of this size would meet the plausibility requirement and the door leaf 20 in closing movement direction 24 push the object. Only when the object 32 reaches a position violating the plausibility condition, the closing movement in the direction of arrow 24 is terminated and the object can be removed from the active light grid area of the monitoring area 22 of the protective beam positions P3 to Pn.
  • FIG. 6 5 shows a schematic diagram of the protected gate 50 when detecting a large object 32 in different positions 32, 32 'and 32 "within the active light grid 10 with the protective beam positions P3 to Pn. It is shown that in each of the positions of the objects 32, 32 shown 'and 32 "the plausibility condition is met, since the respective parallel protection beam S3 is switched or interrupted for the first time and both the trailing auxiliary protection beam N3 and the leading secondary beam V4 of the subsequent switching beam position P4 of the object 32 in the positions 32, 32' and 32" Thus, when moving further in the closing movement direction 24 of the door leaf 20, the bulky objects 32, 32 'and 32 "are urged into a position in which the plausibility condition is no longer met, since already the next protection beam S4 without interruption of at least one trailing or leading Mauschutzstrahls additionally switched bz w is interrupted.
