Definitions
- the invention relates to a security system for securing a particular vertically moving, guided movement element against unwanted collisions according to the preamble of claim 1.
- an interface is provided to output or read in the current position of the movement element. If the possibility arises of transmitting the end position of the movement element to the control, then e.g. To check if the movement element behaves properly. In the final position, e.g. Photoelectric sensors of the object detection means "can not see”. If z. For example, if a door is forced out of the intended path by wind power, which is not excluded in flexible roll-up doors, the controller may receive a corresponding signal, e.g. a stop signal is transmitted.
- the object detection means for example light barriers
- the light barrier density is greater shortly before the end position of the moving element than in the remaining area.
- the end area eg floor area
- a distance of the light barriers of 5 cm and in the remaining area of 20 cm realized.
- elements of the cut-off means which are fastened to the movement element, have a predetermined distance to the front edge. Because the leading edge of moving elements, e.g. Gate elements, is usually not suitable for attachment of objects. It is usually soft, on the one hand sufficient to close a gap between the door element and a ground level, on the other hand, the risk of injury in unwanted collisions is reduced.
- receivers of the disconnection means are arranged offset relative to receivers of the object detection device.
- the individual components of the security system on one side of a moving element need not necessarily be in be housed a unit. It is conceivable that, for example, individual sensor pairs or groups of sensors can be mounted in a communicating manner via a bus. This makes it possible to achieve greater flexibility if the object detection device and / or switch-off means of the security system are to be adapted to different structural conditions, in particular smaller or larger surveillance areas.
- Conceivable are laser scanners, distance sensors, such. Time of flight sensors or stereo cameras, photoelectric sensors and retro-reflective sensors, just to name a few.
- FIG. 1 - 3 in each case the left side of different Torommessystemen 1, 2, 3 shown. From a gate element 4, the lower left corner is shown schematically in each case.
- the Torommessysteme 1, 2, 3 comprise on the left side in each case a receiver strip 5, 6, 7.
- the associated transmitter send out the monitoring light beams 8 to a respective receiver 9, are in the Figures 1 - 3 not to be seen.
- the monitoring light beams 8 ensure that when an object enters an area 10 below a front edge 4a of the door element 4 due to an interruption of the monitoring light beams 8, the gate element 4 stops, g reverses to prevent collisions with the object.
- a transmitter 12 is positioned in the left front area of the gate element 4, a transmitter 12 is positioned.
- the transmitter 12 cooperates with receivers (not shown) which, in principle, could also be the receivers 9, whereby the monitoring light beams 8 for the object recognition are successively blocked when the door element 4 is shut down.
- the locked monitoring light beams are in the Figures 1 - 3 shown in dashed lines.
- the transmitter 12 preferably cooperates with the receivers in such a way that, before reaching a monitoring light beam 8 through the front edge 4a of the goal element, a respective receiver recognizes that the gate element is in this position by a signal emitted by the transmitter 12, whereby the respective receiver transmitter pairing for the Monitoring light beam is placed in a passive state.
- the receivers of the turn-off means are arranged offset to the receivers for the respective monitoring light beams 8.
- the signal path with shutdown means 12, 13, 14, 15, 16 is subjected to as few disturbances as possible.
- a type of light guide 18 can be used, which has a defined receiving lobe 19 and a defined transmitting lobe 20 on a transmitter 21 and with respect to a receiver 22, so that also a misinterpretation of signals can practically no longer take place (see FIG. 5 ).
- a collimation device are used, for.
- a lens 22 a which makes it even more difficult that a reflection of light from the transmitter 21 takes place to the receiver 22, which is interpreted as a shutdown signal.
- a diaphragm 22 b may be provided.
- a modulator after transmission 21 and an analyzer in front of the receiver 22 can be arranged in the light path, which further increases security.
- FIG. 6 a reflector 27 is shown.
