Definitions

  • the present invention relates to an elevator installation and a method for operating an elevator installation with a shaft, in which at least a first car and a second car for operating destination calls can be moved separately upwards and downwards. Further, a control device is provided which determines a suitable car to operate the destination calls.
  • double-decker lifts In order to transport a large number of people within a shortest possible time by means of a lift installation, especially in commercial or office buildings, so-called double-decker lifts are known in which two cabins directly above one another and firmly connected to one another always approach two adjacent floors at the same time.
  • elevator systems are known within a short time, in which at least two cars can be moved upwards and / or downwards independently of one another in a common shaft.
  • the first car is either temporally synchronous with the second car or staggered in time with the second car, but still within the time period of a second car, depending on at least one operating parameter Driving the second car is moved.
  • the term "operating parameter" refers to all factors which influence the use of the elevator installation, both with regard to past use, current use and future use. Preferably, this dependency relates to only one operating parameter. If necessary, the operating parameter can also change over the course of the operating time of the elevator installation.
  • the operating parameter is based on the traffic or traffic volume, that is, for example, on the number of destination calls made by the users or on the number of persons or objects to be transported.
  • the transport volume is preferably determined by the number of delivered destination calls.
  • the transport volume can be determined by the number of persons or objects to be transported.
  • the number of delivered destination calls can be detected in a simple manner by the control device.
  • the number of persons to be transported can be easily determined by means of at least one detection device, such as a sensor or a light barrier, which can then transmit the determined data to the control device.
  • a detection device can be provided for example in the access area of a passenger elevator or in the loading area of a freight or goods lift.
  • the first and second cars are mechanically coupled via a coupling in the temporally synchronous or staggered process.
  • a temporary biplane is formed during the temporally synchronous or staggered process, in which the small distances from one car to another need not be checked by other special collision prevention means such as sensors, controls, etc.
  • the distance of the clutch from one to another car adjustable, so that different floor heights can be compensated.
  • the invention can be used in passenger lifts, goods lifts and goods lifts.
  • the first and the second car are moved synchronously or offset in time from a predetermined limit value of the operating parameter.
  • This first limit value can be determined and changed, for example, by means of predefined values or by operating data continuously determined during the operating time of the elevator installation, for example by means of average values over certain time periods.
  • the limit can be set at different times of the day, for example in peak times at the beginning and at the end of a working day and depending on the day of the week at different levels.
  • the first and the second car from a predetermined further limit of the operating parameter is no longer synchronously or offset in time.
  • the further limit value is at a lower transport volume than the first limit value.
  • the advantage of this switching on and off of the time-synchronous or staggered method of the cars is that at low traffic destination calls individual not timed synchronously or staggered cars can be allocated and that in dense traffic a collective operation takes place with timed synchronously or offset moved cars.
  • the operating parameter can also be set by means of the ratio of the orientations of the directions of travel of the first and second car.
  • the first car and the second car can be moved in synchronism with one another in time if the two vehicles have been assigned the same direction of travel by the control device for providing the car to the start floor or to operate the respective destination call from the start floor.
  • a temporally offset method of the first and second car can then be provided if one of the cars has to travel a comparatively short distance in relation to the other car to operate the respective destination call. This results in the advantage that a car before the ride of the other car is completed can be set in motion and thus does not have to wait until the ride is completed.
  • the operating parameter can be determined by a track section of the shaft.
  • a specific track section for example between two predetermined floors, or the length of the track section can be used as a decisive factor.
  • the first car or the second car is moved empty. That's how it works of a destination call to be overcome in critical cases.
  • timed offset cars can be moved in synchronism with each other by an empty ride at least one car at the latest at the next drive again.
  • the position of the disturbing car and the positions of the destination floors of the destination calls can be used.
  • the destination call is delivered to the control device by means of a destination call tableau, a destination call terminal or a mobile communication unit, such as a mobile telephone.
  • FIG. 1 shows a schematic vertical section through an elevator installation for carrying out the method according to the invention.
  • FIGS. 2 to 6 various embodiments for use in the elevator system shown in Fig. 1 will be explained.
  • Fig. 1 shows schematically an elevator system in the form of a passenger elevator for a commercial building.
  • the elevator installation comprises a shaft 10, in which a first car 20 and a second car 30 can be moved separately upwards and / or downwards.
  • the building comprises eight floors 50 to 57, which can be reached by persons located in the building via the elevator installation. On each of these floors 50 to 57 is located on the outside of the shaft wall a destination call tray 60, which allows the user to make a destination call to the desired destination floor.
  • the elevator installation according to FIG. 1 is a traction sheave elevator installation, wherein the first elevator car 20 is moved or braked by means of a drive unit 22 and a brake unit 24. Similarly, the second car 30 is moved or braked by means of a drive unit 32 and a brake unit 34.
  • Supporting cables or carrying straps and counterweights are formed in a conventional manner and, like the shaft and cabin doors and other operating and display elements for the sake of simplicity not shown or only hinted.
  • a first control unit 42 is connected to the drive unit 22 and the brake unit 24 in connection.
  • a second control unit 44 is connected to the drive unit 32 and the brake unit 34.
  • a control device 40 is provided, which communicates with the first control unit 42 and the second control unit 44 as well as with all target call panels 60 of the individual floors 50 to 57 in the data exchange.
  • a plurality of people who want to be promoted to the sixth floor 55 and have submitted the corresponding drive request via the Zielruftableau 60 to the controller 40, hereinafter referred to as the first destination call shall be. Furthermore, there are several people in the fifth floor 54 who want to be transported to the eighth floor 57. This driving desire should represent here the second destination call.
  • the first car 20 is located on the first floor 50 and the second car 30 is located at the level of the third floor 52.
  • the first car 20 and the second car 30 starting from the initial situation shown in FIG temporally synchronous in the direction of the two starting floors 51, 54, in which the persons to be transported are located, proceed.
  • the two cars 20, 30 are set in motion at substantially the same time.
  • the manhole and the car door open, so that the persons located on the second floor 51 can enter the cabin of the first car 20.
  • the occupants of the fifth floor 54 may enter their cabin.
  • the first car 20 moves from the start floor 51 into the desired destination floor 55, while the second car 30 is moved from the start floor 54 into the destination floor 57.
  • the first car 20 due to the shorter route first reaches its starting floor 51. Therefore, the first car 20 can also start its service travel at an earlier time than the second car 30.
  • the operating rides of the two cars 20, 30 do not start at the same time, they nevertheless run at least at the same time, so that it is possible to speak here of a time-offset method of the two cars 20, 30.
  • the operating runs of the two cars 20, 30 comprise a common route section along the Floors 54, 55. Furthermore, the two cars 20, 30 each have the same direction of travel during both the entry and the service runs.
  • the exemplary embodiment according to FIG. 3 differs from the exemplary embodiment according to FIG. 2 in that the second car 30 is first positioned in the second floor 51. Based on this situation, first the second car 30 is moved in the direction of the start floor 54. As soon as the second car 30 is located in the area of the third floor 52, the first car 20 is moved from the first floor 50 into the start floor 51. Thus, the first car 20 is set in time offset to the second car 30 in motion. After the two cars 20, 30 have reached their respective start floor 51 or 54, the service runs are carried out as in the above embodiment of FIG. 2.
  • the exemplary embodiments according to FIGS. 4 and 5 differ from the exemplary embodiment according to FIG. 3 in that the first car 20 and the second car 30 are mechanically coupled via a coupling 23 in the temporally synchronous or staggered method.
  • a coupling 23 enables engagement and disengagement and can be realized with the known form-fitting means such as a latching coupling, but also via non-positive means such as a magnetic coupling, and so on.
  • the engagement or disengagement is advantageously carried out automatically when approaching or removing the cars 20, 30.
  • the clutch 23 may be provided with or without protection against unwanted disengagement. With knowledge of the present invention, the skilled person can realize many variants of such a coupling.
  • the embodiment shows 5 shows a hotel with an entrance hall on the lower floor 50 ', which is higher than the upper floors 51 to 57 with identical floor level.
  • the embodiment of FIG. 4 shows an office building in which all floors 50 to 57 are identical.
  • the cars 20, 30 are positioned in the floors 50, 50 'and 51 coupled via the coupling 23.
  • the cabin floors are aligned flush with the floors of the floors.
  • the comparison of the embodiments according to FIGS. 4 and 5 shows that the distance of the clutch 23 of the cars 20, 30 is adjusted so that the height difference between the entrance hall 50 'and the other floor 51 is compensated by increasing the distance of the clutch.
  • Such an adjustment of the distance of the coupling 23 can be easily and quickly realized by a person skilled in the art with known means such as a spindle drive, a pantograph, etc. Again, the skilled person can realize a variety of variants of such adjustment of the distance of the clutch with knowledge of the present invention.
  • the persons located on the second floor 51 can enter the cabin of the first car 20.
  • the persons located on the seventh floor 56 can enter his cabin. Due to the same starting time and the same distance to the respective start floor 51, 56, the two cars come 20, 30 about the same time in the starting floors 51, 56 at.
  • the second car 30 first moves from the start floor 56 in the direction of the desired destination floor 54, in order to carry out the service run for the operation of the first destination call.
  • a time interval ie offset in time, but still during the journey time of the operating travel of the second car 30, the first car 20 starts from the start floor 51 in the direction of the destination floor 55.
  • the time offset is selected such that there is sufficient time to the second car 30 after transport of persons in the fifth floor 54 immediately back to move upwards and at least to the seventh floor 56.
  • the first car 20 can then approach the destination floor 55 of the second destination call unhindered.
  • the Einschfahrten the cars begin 20, 30 substantially at the same time, that is synchronized in time, while the cars 20, 30 are moved in the subsequent operating trips offset from one another.
  • the two cars 20, 30, both in the Einschreibfahrten as well as in the service trips each opposite directions.
  • the exemplary embodiments of the method according to FIGS. 2 to 6 described above are characterized in particular by the fact that in particular in the case of a large number of persons to be transported, that is to say in the case of a high transport volume, the two cars 20, 30 are displaced either synchronously in time or at different times.
  • the selection of the procedure is carried out by means of the control device 40 and suitable algorithms. In this way, for example, it can be dispensed with to keep a common for both cars 20, 30 roadway section only for one car and lock completely for the other car until the completion of the respective operating trip.
  • an increase in the transport capacity can be achieved in a simple manner.
