Definitions

  • the present invention relates generally a safety device for motor-driven Systems such as Segment or roller doors, according to the preamble of claim 1.
  • the Safety device is used to detect an in the trajectory of a system component, e.g. a gate, rolling grille, lifting gate and the like Object.
  • Such security systems are, for example from documents DE-U-8615042 or DE-A-3416546 known.
  • DE-U-8615042 one is from one Safety bar made of elastomeric material a finishing profile on one side with a lamp and on the other side with one provided photosensitive resistance. If the Safety bar meets an obstacle, the Beam of light interrupted, causing an engine brake actuating switching pulse is generated.
  • DE-A-3416546 relates to a security device for stopping moving objects.
  • the light barrier arrangement consists of a light transmitter and a light receiver that both ends of one having a light channel Profile rail are arranged.
  • EP-B-0325602 is a safety arrangement for roller shutters known in which the switching device from a There is a light barrier, its transmitter and sensor elements on both sides of the end profile in one distance corresponding to the braking distance below this are arranged on support arms.
  • the support arms are slidably guided in the respective brackets, which is connected to a lower part of the door leaf are. If the support arm against the floor or strikes a stop, the encoder and transducer elements relative to the door leaf towards it moved and come to the end of the closing movement of the gate in a position at least in the Height of the bottom edge of the door leaf.
  • EP-B-0284066 is a high-speed door with a in the area of the lower edge of the end profile provided switching device known in their Actuation the brake is applied.
  • the switching device consists of a light barrier, the Transmitter and transducer elements on both sides of the end profile in a way corresponding to the braking distance Distance below this in the area of the bottom Ends of stamps are arranged in guides the end profile or lateral sword-like Extensions are inserted. When it hits the stamp on the ground or a stop immerse the stamp in the guides so that the end profile is supported on the floor can.
  • Light curtain systems either on one side of the Door leaf, or, to improve protection, can be mounted on both sides of the door leaf. In the former case, there is insufficient personal and property protection on the non-meshed one Side of the door leaf. In the latter case the effort too high and the light curtain system too expensive. In addition, both systems have in common that they are prone to switching errors, e.g. if Power supply components such as Power cable at external weather influences in the beam path of the Immerse the light grid in an uncontrolled manner.
  • the object of the present invention is therefore a safety device for motor-driven To create systems of the generic type, the maximum with simple assembly technology Security for anyone to be monitored System components on the one hand and for operators on the other hand offers and those with low control technology Effort.
  • the radiation state control device so that works at once certain position of the system component (Initialization phase) automatically a predetermined one Activation algorithm for radiation protection for example in the form of individual light barrier systems can expire.
  • the algorithm according to the invention allows, for example, the rays into the trajectory to lay the system component, so that now a single light grid system is sufficient to control the to monitor the entire movement path of the system components, thereby the device engineering effort is further reduced. Because the current position the various activation states of the system component of the light barriers, synchronized the safety device automatically with the Movement of the gate.
  • the safety device according to the invention is can be used individually. You can be with any moving system components, e.g. powered vehicle windows, cabin doors, tool slides etc. simply combine without the respective drive control of the system component would have to be modified.
  • any moving system components e.g. powered vehicle windows, cabin doors, tool slides etc. simply combine without the respective drive control of the system component would have to be modified.
  • the optimal algorithm for determining the Activation states of the individual rays is Subject of claims 5 and 6. With this Algorithm can be taken in order from the pre-current one Edge of the system component (gate) passed through Beams sequentially and automatically into one passive state X, an inactive state 0 and be brought to an active state 1. This States become with the movement of the leading Pass through the edge sequentially.
  • the security device at the same time as a detector device to determine the position and the direction of movement the system component (gate) become.
  • the safety device is not on any Orientations of the movement of the system component limited.
  • roller door 11 of width BR and height HR in a known manner essentially from two sides arranged hollow guide profiles 12 and 13 with U-shaped cross-section, one on the side Guide profiles resting cross member 14 in which a Motor and a winding shaft driven by the motor is housed, and one in vertical slot-like guides in the side guide profiles 12 and 13 guided and on the winding shaft wound flexible door leaf 15.
  • a roller shutter 11 is assigned a preferably optical safety device that is independent of the door control, ie, works autonomously, and is preferably optical.
  • a bar 17, 18 of a light grid arrangement for example based on infrared rays, is attached to both sides of the door leaf 15, one bar accommodating the light transmitters and the other bar accommodating the light receivers, so that a multiplicity of one-way light barriers with the rays 19 -1 to 19-n is formed.
  • a receiver is assigned to each transmitter.
  • the rays run parallel to each other.
  • the rays 19 can also run obliquely.
  • the strips 17, 18 are attached in such a way that the surface 20 spanned by the light beams 19 has at least one line 123 (FIG. 3) in common with the movement surface 122 (FIG. 3) swept by the leading gate edge 21 of the door leaf 15.
  • the levels coincide, ie the light grid lies directly in the closing level of the door leaf. All embodiments have in common that the strips 17, 18, 117, 118 are attached to the guide rails 12, 13 and 112, 113, respectively. According to FIGS.
  • FIG. 2 shows that the monitoring height H can be limited to a reasonable level, for example 2500 mm.
  • the figure further shows that the shape of the door leaf can be arbitrary, for example can be formed by folded segments 224.
  • the leading edge 221 is in turn guided in a guide profile 213 in which the light bar 218 can also be accommodated.
  • Figures 6 and 7 show variants for the arrangement of the light strips in or on the relevant guide profile: According to FIG.
  • the guide profile 312 is provided with a further profile chamber which is adapted to the light bar 317 and which adjoins the guide chamber 325 for a roller 326 of the door leaf 315. Retrofitting a gate with the safety device according to the invention is carried out here by exchanging the guide profile. According to FIG. 7, the guide profile 412 can remain essentially unchanged when retrofitting.
  • the web 427 of the guide profile 412 receives a series of bores 428 in a hole pattern corresponding to the light barrier arrangement.
  • the strips 417 are attached to the outside of the web 427.
  • the safety device has a special control circuit with which the beams are sequentially assigned different activation states depending on the position and movement of the door leaf. This is explained in more detail below:
  • the beam 19-0 that is closest to the leading edge 21 when the gate closes receives the activation state ZERO from the control circuit 40, ie when this light beam passes through the edge 21 shortly thereafter, this light barrier does not interrupt the closing movement of the door leaf Signal off.
  • All rays 19-x lying behind the ray 19-0 in the direction of movement and which have already been covered by the door leaf assume the inactive state X.
  • the beams 19-1 to 19-n are in the active state 1, ie any obstacle in the area of the beams 19-1 to 19-n ultimately delivers an output signal SA which is applied to an interrupter or inverter relay 41 to stop or reverse the drive of the motor.
  • SA an interrupter or inverter relay 41 to stop or reverse the drive of the motor.
  • the control 42 of the door drive is thereby detached from the safety device 40, ie that both devices 40, 42 work independently of one another.
  • the control circuitry ensures that beam 19-0 becomes passive beam 19-x while beam 19-1 becomes new beam 19-0.
  • FIGS. 8 and 9 show a possible embodiment for the control of the light grid and the evaluation of the signals applied to the individual light barriers.
  • Figure 8 shows the transmitter part 40-2
  • Figure 9 shows the associated receiver part 40-1.
  • the individual transmitters S1 to Sn can be addressed and evaluated individually, for example in the form of light-emitting diodes, and the receivers E1 to En in the form of phototransistors, ie the light barriers.
  • the individual transmitters such as light-emitting diodes
  • the signals received by the receiver can be evaluated individually and selectively by means of the microcontroller on the receiver side.
  • Filter (43), amplifier (44) and threshold value circuits 45 can be used to eliminate interference.
  • step 1 The position of the leading gate edge is determined, whereby the signals present at the individual addresses can already be used here.
  • the current position of the gate edge is at the xth address, ie at the xth beam. If an object is detected during the position determination, the control circuit outputs an output signal SA, ie the outputs are set.
  • FIGS. 11 to 13 show further exemplary areas of application for the safety device:
  • the safety device is assigned to a cabin door 450 that closes horizontally.
  • a light bar 517 is embedded in the floor and has a complementary ceiling bar (not shown).
  • the door 450 is driven by a motor M that has a controller 542.
  • the beams of the light bar can in turn be controlled and evaluated individually by means of the control circuit 540.
  • Another advantageous application example is shown in FIG.
  • light strips 617, 618 are arranged on the door frame of a motor vehicle, preferably in the critical closing area BS, so that there is complete personal protection against pinching body parts.
  • the control circuit 642 of the window drive 660 remains unaffected by the safety device.
  • the operation of the control circuit 640 corresponds to the examples described above. It can be seen from FIG. 12 that the light strips can be easily adapted to the system conditions (space, size, orientation).
  • FIG. 13 shows an exemplary embodiment for the movement monitoring of elevator cabs 770 which move vertically up and down. Light strips 717A, 717B and 717C are again installed in the plane of movement of the cabins.
  • circuit 740 is constructed or programmed such that only those beams which are covered by the cabin 770 have the activation state X, the beam de state closest to the momentary movement direction and the state ZERO and all other beams Take state 1.
  • the radiation protection is not necessarily on light rays limited. It is also possible that the transmitter and receiver assigned to a single guide rail are, so that a reflection light barrier is used. It is also possible with a number of reflection light buttons to work.
  • the light source for example, a conventional one Incandescent lamp, a light emitting diode or a laser.
  • the light receiver can be a photoelectric receiver such as. a photocell, a photoresistor, a Photo element or a photodiode can be used.
  • the invention thus creates a safety device for externally driven systems, for protection the movement of a system component against unwanted collision with one in the trajectory of the system component, whereby the object monitoring system component along a predetermined Track (ET gate level) is guided, with the trajectory of a leading edge of the system component preferably monitoring optical radiation protection, preferably based of infrared rays, the at least two, preferably at least three or a plurality of in the direction of movement the system components are staggered, preferably has parallel rays, which are broadcast on one side of the system component and received or reflected on the other side and with a safety circuit with which the movement of the system component stopped or is reversed when an obstacle in the trajectory the system component is detected, thereby characterized that the radiation protection such is arranged that the one defined by the rays Radiant area (E) with that of the leading one Edge swept movement area at least one Line has in common, and that the self-sufficient Safety device a radiation status control device that has the rays depending on the position and movement of the system component different
