Definitions
- the present invention relates generally to one Safety device for motorized gates, such as e.g. Segment or roller doors, according to the preamble of Claim 1.
- the safety device is used for Detection of one in the movement path of a gate, Rolling grille, lifting gate and the like. Located object.
- Such security systems are for example from the Document DE-U-8615042 or DE-A-3416546 known.
- DE-U-8615042 is one made of a tube made of elastomeric Material existing safety edge of a finishing profile on one side with a lamp and on the other side with provided with a photosensitive resistor. 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.
- Safety device for stopping motorized to reach moving objects Light barrier arrangement from a light transmitter and one Light receivers at both ends of a light channel having profile rail are arranged. When it hits an obstacle becomes an elastically deformable one Material existing profile rail while reducing the Cross section of the light channel squeezed together so that the Light beam is interrupted.
- Light barrier arrangements in at least that Distance of the door leaf following the corresponding distance in front of the leading edge of the final profile of the door leaf to be arranged so that the movement of the door leaf is stopped when an obstacle blocks the light beam Light barrier arrangement interrupts. Since the light beam in runs a distance in front of the door profile, it is ensured that the final profile is not with a obstacle interrupting the light beam is coming.
- EP-B-0325602 and EP-B-0284066 are examples of this.
- the Switching device consists of a light barrier, the Encoder and transducer elements on both sides of the end profile in a distance corresponding to the braking distance below this are arranged on support arms.
- the support arms are slidably guided in respective brackets, which with are connected to a lower part of the door leaf. If the Support arm hits the ground or a stop the encoder and transducer elements relative to the door leaf this shifted towards the end of the Closing movement of the gate in a position that is at least at the level of the bottom edge of the door leaf.
- EP-B-0284066 is a high-speed door with a Area of the lower edge of the end profile Switching device known that when actuated the Brake applied.
- the switching device consists of a light barrier, its transmitter and sensor elements on both sides of the end profile in a braking path corresponding distance below this in the area of lower ends of stamps arranged in Guides of the end profile or side sword-like extensions are inserted. At the Impact of the stamp on the floor or a stop immerse the stamp in the guides, so that the End profile can be supported on the floor.
- these are Encoder and transducer element on part of the door leaf arranged, which leads to the donor and Sensor elements can be moved with the door leaf. Because of the electrical lines and are subject to this movement other components of the electrical circuit that are stretch between door leaf and frame, strong dynamic loads caused by vibrations of the Door leaf and continuous bending stress caused. In addition, dirt, dust and Water on various electrical system components deposit and decrease in performance or malfunction of the system. As a nuisance in these known The fact that the electrical supply of the encoder and receiving elements must be passed through the gate so that the construction the gate or the gate segments must be adapted to this. This affects the flexibility of the user, however also by the manufacturer when it comes to door design.
- the object of the present invention is therefore a To create safety devices of the generic type, the maximum with easy installation System and personal protection for a door of any design offers and with little control effort gets along.
- the Beam state control device works so that at once determined position of the gate (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 this e.g. to place the rays in the gate movement path so that now a single light grid system is sufficient to to monitor the entire path of movement of the gate, making the device outlay is further reduced. Because the current position of the gate the different Defines activation states of the light barriers, the safety device synchronizes itself with the movement of the gate.
- a connection to the Control system of the gate is no longer required, so that the security device according to the invention quasi as "Stand-alone solution" for every one on the market Gate or the like. Can be retrofitted. In addition, the required control circuit simple. With the safety device according to the invention results in a security level of the Monitoring. Because every object that monitored Touching the surface of the door leaf inevitably leads to a response of the safety device and already prevents the drive unit from starting Gate. Any control errors, but also inertia-related movement deviations (running larger moving masses) are from the start compensated.
- claims 8 and 9 lead to an advantageous signal flow in the system and one constant maximum safety status of the rays, too if the gate is only opened in gaps and then is closed again.
- the Safety device simultaneously as a detector device to determine the position and direction of movement of the Tores are used.
- the Sensitivity of the safety device there is particularly high are kept where specific hazard patterns occur, such as. at a low height above the ground in which is flat moving booms of forklift vehicles.
- the Cross-beam technology according to claim 13 has the special advantage that simpler light protection strips with larger division pattern and equal division of the Transmitter / receiver can be used.
- the safety device is not on any Orientations of the gate movement or on certain Door leaf designs limited.
- a roller door 11 of width BR and height HR is in known manner essentially from two laterally arranged hollow guide profiles 12 and 13 with U-shaped Cross section, one on the side guide profiles resting cross member 14, in which an engine and an engine driven winding shaft 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.
- the roller door 11 is one of the door control independent, i.e. self-sufficient, preferably optical Safety device assigned. This is for both Sides of the door leaf 15 each have a bar 17, 18 one Light grid arrangement, for example based on Infrared rays attached, a bar the Light transmitter and the other bar the light receiver picks up, so that a variety of one-way light barriers is formed with the rays 19-1 to 19-n.
- each transmitter is on Assigned recipient.
- the rays also run parallel to each other. However, this is not mandatory required.
- a transmitter can have multiple receivers be assigned.
- the rays 19 can also run obliquely.
- the strips 17, 18 are attached such that the the light rays 19 spanned area 20 with the leading gate edge 21 of the door leaf 15 painted Movement area 122 (FIG. 3) at least one line 123 ( Figure 3) has in common.
- the levels coincide, i.e. the The light curtain lies directly in the closing level of the Gate leaf.
- FIG. 5 shows that the monitoring height H accordingly to a sensible Dimension can be limited, for example to 2500 mm.
- Figure further shows that the shape of the door leaf can be any can be formed, for example, by folded segments can.
- the leading edge 221 is again in one Guide profile 213 out, in which the light bar 218th can be included.
- Figures 6 and 7 show variants for the arrangement of the Light strips in or on the relevant guide profile:
- the guide profile 312 with a another profile chamber adapted to the light bar 317 provided that the guide chamber 325 for a role 326 of the door leaf 315 connects. Retrofitting one Tores goes with the safety device according to the invention here by exchanging the management profile.
- the guide profile 412 at Retrofitting remains essentially unchanged. Get here the web 427 of the guide profile 412 a series of Bores 428 in one of the light barrier arrangement corresponding hole pattern. The strips 417 are on the Mounted outside of the web 427.
- the Safety device So that the rays leading from the transmitter to the receiver the light barrier arrangement in the movement area of the leading edge 21 can run, has the Safety device with a special control circuit of the rays sequentially depending on the Position and movement of the door leaf different Activation states can be assigned. This will be in the the following:
- the rays 19-1 to 19-n are active State 1, i.e. any obstacle in the field of rays 19-1 to 19-n ultimately provides an output signal SA, the applied to an interrupter or inverter relay 41 to interrupt the drive of the motor or to reverse. It can be seen from the illustration in FIG. 1 that that thereby the control 42 of the door operator of the Safety device 40 is disconnected, i.e. both Devices 40, 42 work independently of each other.
- the safety device also serves as Device for determining the position of the door leaf. For this purpose, preferably when opening the gate released beams sequentially over the Transition state ZERO to active state 1 armed switched.
- Figures 8 and 9 show a possible embodiment for controlling the light grid and evaluating the signals present at the individual light barriers.
- Figure 8 shows the transmitter part 40-2
- FIG. 9 shows the associated part Receiver part 40-1.
- MUX1 to MUX4 By means of a multiplexer arrangement known per se MUX1 to MUX4 are the individual transmitters S1 to Sn e.g. in Form of light emitting diodes, and the receivers EI to En in the form of phototransistors, i.e. the light barriers individually addressable and evaluable. That is, the individual channels, such as. LEDs are controlled by the micro controller - selectively switch on and off individually and selectively.
- the receiver such as. signals picked up by the photo transistors individually and selectively by means of the receiver Micro-controllers can be evaluated.
- To eliminate Interference can be filter (43), amplifier (44) and threshold circuits 45 (Schmitt trigger) are used become.
- Photoelectric sensors can be hidden individually predetermined boundary conditions of the gate, e.g. a brief entry via a threshold ramp or that To show the presence of a current high snow cover.
- the system is initialized in step 1.
- the position of the leading gate edge is determined, where already here to those at the individual addresses Signals can be used.
- the current position the gate edge is at the xth address, i.e. on the umpteenth Beam.
- the control circuit gives an output signal SA down, i.e. the outputs are set.
- the light curtain will start from position x + 2 evaluated, i.e. the address x + l receives the state NULL and all rays x + 2 to x + n are active.
- the transmitter and receiver are one single guide rail are assigned so that a Reflection light barrier is used. It is also possible with a series of reflection light buttons too work.
- the Light source for example a conventional light bulb, be a light emitting diode or a laser.
- a light receiver can a photoelectric receiver such as a Photocell, a photo resistor, a photo element or one Photodiode can be used.
- the invention thus creates a safety device for preferably vertically moving, motorized gates, such as. Segment or roller doors, whose door leaf is guided is movable.
- the path of movement of a leading gate edge is preferably from optical radiation protection, preferably monitored on the basis of infrared rays.
- the radiation protection has at least two, preferably at least three or a plurality of in the direction of movement of the gate staggered, preferably parallel Beams emitted on one side of the gate and received or reflected on the other side of the gate become.
- a safety circuit is also provided, with which the closing movement of the gate is stopped when an obstacle in the path of movement of the gate is detected.
- the radiation protection is arranged in such a way that the Rays defined radiation area with that of the leading gate edge swept movement area has at least one line in common, and that the self-sufficient working safety device a radiation state control device that has the rays in Depends on the position and movement of the gate assigns different activation states.
