Definitions

  • the invention relates to a locking device for a security door with a Bolt for mechanical locking and an electronic bolt in the form of a safety sensor.
  • Machines on which dangerous process sequences take place e.g. Press or welding robots or the like are secured with separating protective devices. These are usually existing enclosures from a lattice fence, which is embedded in a profile frame.
  • the safety sensor has an actuator on the movable door, whose approach to a sensor base part with integrated evaluation unit, which is attached to the door frame, is detected. By the safety sensor moves the actuator closer to the sensor base part according to its function in the safe state and signals one for the Safety function defined state, so that when closed and locked Door the safety sensor outputs a corresponding locking signal and at unlocked door an unlock signal.
  • the overall design of the access doors must be coordinated his. This both in the overall mechanical construction of the access door, as well in the components used for the required security.
  • the disadvantage is that in known locking concepts to secure Access doors for doors opening to the left or to the right different Basic devices are used. This causes increased inventory and hence additional costs.
  • the locks work according to a mechanical Principle, whereby by a mechanical actuation, a bolt or a shaft in a locking mechanism is performed.
  • Another disadvantage is that weaning or sagging of the door directly on the locking mechanism and Safety sensor affects.
  • known mechanical doors are additional Devices (stops) required to prevent the door from swinging open, if it accidentally falls from the open position.
  • the object of the invention is an improved To provide a locking device with the aforementioned disadvantages can be avoided.
  • the locking device for a security door Door stop a bolt for mechanical locking and one Safety sensor, consisting of an actuator and a sensor base part, the mechanical latch and the actuator in a common housing are provided and the housing for both a left and for one door opening to the right is designed.
  • the locking device can be used universally, ensuring that that the non-contact safety sensor is integrated.
  • Various Variants are all that would have to be checked due to the security requirement unnecessary.
  • the housing is preferably symmetrical
  • the actuator of the safety sensor is in a separate housing part is provided, on the one hand, mechanical protection of the actuator, which e.g. contains sensitive electronic components, guaranteed even when the door is open. For example, is getting stuck with clothes or the like. prevented on the actuator. Of This also provides increased protection against manipulation against disassembly. The actuator is also better protected against vibrations. Overall will thereby further increasing the functionality and thus the security.
  • the actuator together with the bolt can be actuated, in particular they are connected to one another.
  • the door stop is on the side so that the door does not swing when it is closed over the door over, preferably the door stop symmetrically on the housing is arranged and thus protrudes on both sides of the housing without Change the door hinge or without changing the attachment of the Door stop on the housing the locking device for right and left to be able to use opening doors.
  • the door stop can be released with the housing connectable.
  • the security mechanism consisting mechanical latch and safety sensor, but not in its function affect.
  • a possible sagging of the door is due to the support for the Door stop prevents and does not affect the locking shaft and the safety sensor straight from.
  • the support is formed from a profile that at the same time forms a locking receptacle that keeps the bolt in the closed position Condition of the locking device for locking picks up.
  • the safety sensor is advantageously in proven transponder technology educated.
  • a locking device 10 shown in the drawing has one on one Swing door attached lock part 12 and a fixed to a door frame 14 Counterpart 16 on.
  • the locking device 10 comprises a mechanical one Locking device 18 and a security sensor 20 that detects whether the Door is closed and locked.
  • the locking device 18 has a bolt 22, which in a housing 24 in Direction of a double arrow 32 is slidably mounted and a locking receptacle 26, which is fixed to the door frame 14.
  • the housing 24 is more suitable Way, for example via fastening means 28 on the door.
  • the latch 22 has a handle 30 which can be operated from both sides of the door is. The handle 30 is large enough so that the latch 22 with work gloves is operable.
  • the bolt 22 is shown in its locked state. there the bolt 22 is received with its end 34 in the locking receptacle 26 and thus set in the pivoting direction of the door so that the door locks is.
  • the locking receptacle 26 consists of a U-profile 36, as shown in Fig. 3 can be seen.
  • One leg 38 of the U-profile 36 has an opening 40 Inclusion of the bolt end 34.
  • the bolt 22 is in a manner not shown in both its locked and lockable in its unlocked position so that it does not accidentally move from one can move to the other position.
  • a door stop 44 is arranged, which the housing 24 is releasably attached, for example screwed.
  • the door hinge 44 projects laterally beyond the door (in FIG. 1 to the left), so that it strikes the door frame 14 when the door is closed. On Swinging through the closing door is prevented.
  • the door stop 44 comes immediately above the U-profile when the door is closed 36 to lie so that when the door lowers or sags, the door through the door stop 44 supported on the U-profile 36 in front of another Lowering is supported and the lock and the safety sensor too then work smoothly and safely.
  • the safety sensor 20 has a sensor base part fixed to the door frame 14 46 and an actuator arranged in a lower, separate housing part 48 50 on.
  • the sensor base part 46 comprises a sensor head 52.
  • the safety sensor 20 is preferably embodied in transponder technology, so that the sensor head 52 and the actuator 50 mutually exchange signals, for example RF signals and as a result an approach of the actuator 50 to the sensor head 52 is determined can be.
  • the safety sensor 20 only gives a "door closed” signal, if the actuator 50 is close enough to the sensor head 52, which is only the case when the door is closed and the latch 22 is in the Locked position (Fig. 1).
  • the actuator is 50 connected to the bolt 22 via a plate 54 by means of suitable connecting means 56, so that latch 22 and actuator 50 only together by means of the handle 30 can be moved.
  • a free end 58 of the plate 54 from the Stand out part 48 when the latch is in an unlocked position is located, that is pushed to the right in the view of FIG. 1.
  • the free end 58 has four holes 60 through which four padlocks in the unlocked position o. Like. Can be guided so that it is ensured that the door cannot be locked unintentionally. Appropriate safety regulations are required the relatively high number of up to four security options using the Padlocks.
  • the housing 24 with the door stop 44 and Latch 22 is formed symmetrically. These components can therefore unchanged on a door opening to the right or to the left.
  • the actuator 50 with the plate 54 can also be used for both variants. It only has to be rotated through 180 ° via the fastening means 56 to the bolt be reattached. Then the actuator 50 is not in the view of FIG. 1 more on the left in the housing part 48 but on the right. The entire locking device is thus with all its advantages for doors opening to the right as well as to the left usable.
