Definitions

  • the invention relates to a method for detecting the state of an elevator car according to the preamble of claim 1 and an elevator system according to the preamble of claim 6, in which the method is applied.
  • a support / drive means (carrying cable, carrying strap) with markings and to scan these markings.
  • An example is the patent publication WO 2004/106209 A refer to.
  • a detector is located at a fixed reference point in the shaft while the support / drive means passes the markers past the detector.
  • the detector is fixed in the region of the drive pulley of the drive unit.
  • the solution described above has the disadvantage that it comprises a detector mounted in the region of the drive unit of a machine room-less elevator. On the one hand, this is difficult to achieve for troubleshooting and / or maintenance, and on the other hand interference fields are present in the field of a modern frequency converter supplied drive unit, which affect the reliability of the detector.
  • the object of the invention is therefore to propose a method and an elevator system of the type mentioned, which do not have the disadvantages described.
  • the object is achieved by a method for detecting the state of an elevator car or an elevator installation, in which markings are detected on a belt-like support / drive means with the aid of at least one detector, wherein the belt-like support / drive means moves during the Ride the elevator car relative to this moves.
  • the detector moves with the elevator car, with the belt-like support / drive means, which carries or moves the elevator car, passing the detector.
  • the detection of the state of an elevator car includes the detection of at least one of the following states: the position of the elevator car in the elevator shaft, the direction of travel, the current vehicle speed, the acceleration.
  • the aforementioned states of the elevator car are determined by the device according to the invention independently of a possible slip in the power transmission between a traction sheave of a drive unit and the support / drive means.
  • the method according to the invention or the elevator installation according to the invention have the advantage that a means already present in the elevator shaft, the belt-like support / drive means, can be used for the condition detection of the elevator car.
  • the moving with the elevator car detector is easily accessible for troubleshooting and / or maintenance, depending on its placement on the elevator car from the roof of the elevator car or from a pit.
  • it is placed in this way outside of an area in which interference fields of a frequency converter or a frequency converter supplied drive unit can affect the reliability of the detector.
  • the markings on the belt-like support / drive means are designed so that the instantaneous position and / or the instantaneous speed and / or the acceleration of the elevator car can be recognized by the scanning of the markings.
  • This has the advantage that no additional installations in the elevator shaft for determining the position and / or the speed of the elevator car must be made. As a result, the cost of installation and maintenance can be kept low.
  • the length of the belt-like support / drive means can change as a result of the current load on the elevator car.
  • This change in length (elongation) can be compensated in the state detection.
  • the elongation of the carrying / driving means can be determined and its influence on the condition detection computationally compensated.
  • the aging-related strain and / or a temperature-related change in length of the belt-like support / drive means in the state detection can be taken into account (compensated) by the information of a preferably installed in the area of the ground floor signal generator is included in the compensation calculation, the each passing the elevator car precise position signaled.
  • the belt-like support / drive means is guided past the detector in the region of a support roller loop of the elevator car, so that a precisely defined scanning distance (effective distance), for example a distance of less than 20 mm, is ensured between the belt back and the detector.
  • a precisely defined scanning distance effective distance
  • the detector in the region of a support roller underlayment caused by oscillating support / drive means disturbances to the state detection are greatly reduced, so that the markers can be accurately scanned by the detector with the smallest possible scanning distance.
  • a device mounted below or above the elevator car is designated, which comprises one or two carrying rollers about which the carrier / drive means is guided in order to support and move the elevator car. For repeatedly retracted carrying / drive means, a corresponding number of such support roller underleavings are respectively present on the elevator car.
  • the belt-like support / drive means has a belt front side and a belt rear side, wherein the belt rear side has the markings and not with drive or support rollers the lift system comes into contact.
  • the belt-like support / drive means is guided so that always only the belt front side comes into contact with the rollers.
  • the attached on the back of the belt markers are not affected in the power transmission between the traction sheave of the drive unit and the support / drive means and when circulating idlers, ie mechanical abrasion or mechanical stress and contamination of the marks are minimized.
  • a belt with a row of teeth on the front of the belt, a V-ribbed belt on the front of the belt, a flat belt, a flat belt, a twin-rope or another carrier or drive means is used as a belt-like support / drive means, which has two belt main surfaces.
  • Such belt-like support / drive means have the advantage that the two belt main surfaces can be designed differently.
  • the front side of the belt-like support / drive means which serves as a contact surface to the drive rollers or elevator rollers, have a means for increasing the traction or for guiding the belt-like support / drive means on the traction sheave or the support or deflection rollers ,
  • optical markings are mounted on the belt-like support / drive means and scanned by an optical detector, for example a reflection detector.
  • the markings are superficially mounted on the belt-like support / drive means. This has the advantage that the strength of the belt-like support / drive means is not impaired.
  • Visible tags provide a variety of low-cost ways to encode information or items.
  • magnetic markers are mounted on the belt-like support / drive means and scanned by a magnetic detector.
  • the markings can be mounted both on the surface and in the interior of the belt-like support / drive means.
  • a magnetic scanning system has the advantage that contamination, eg. By dust or oil, cause no interference. Also, the magnetic markings below the surface, and thus protected against mechanical stress, can be attached.
  • Particularly safe elevator controls can be realized if the markings form a coding which allows a direct detection of the absolute position of the elevator car (11). In comparison with incremental position and position detection, position and position detection using absolutely coded markings is less susceptible to interference. It is particularly advantageous that an absolute position and position detection in case of power failure does not lose the information about the current position of the elevator car. Information about the current speed and possibly the acceleration are derived from the existing position information by the controller.
  • the belt-like support / drive means between the traction sheave of the drive unit and the first support roller on the elevator car possibly also rotated between other support rollers along its longitudinal axis, in order to achieve that provided with the mark surface of the support / drive means ( here as a belt back referred to) is always turned away from the discs and rollers during rotation. This ensures that the markings are not destroyed as a result of abrasion or other mechanical stresses.

  • the structure may for example consist of parallel belt ribs between which belt grooves are formed.
  • the belt grooves and belt ribs may be transverse to the belt longitudinal axis (in this case, the belt may be referred to as a toothed belt) or parallel to the belt longitudinal axis (in this case, the belt may be referred to as a V-ribbed belt, for example).
