Definitions

  • the invention relates to a device for generating Shaft information in an elevator shaft according to the preamble of claim 1.
  • Such a device is known from DE-A-4 401 977.
  • a disadvantage of the known device is that the tape over the shaft height in several places must be supported. Another disadvantage is that Temperature fluctuations directly affect the accuracy of the Impact shaft information. In addition, the perforated tape due to the air circulation in the elevator shaft dirty with oily dust, causing problems and Inaccuracies in the optical scanning of the perforations arise.
  • the invention seeks to remedy this.
  • the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and a device for generating shaft information with simplest means to create.
  • the advantages achieved by the invention are in essential to see that the inventive Setup is largely maintenance-free and not can contaminate and built up from commercially available parts is.
  • the device according to the invention loses Do not set up the position information, learning trips after the power failure are not necessary. Furthermore the device replaces all non-safety-related ones Manhole switch for generating manhole information.
  • the Timing belts serving as information providers are fixed Intervention with the encoder, slip between toothed belt and Encoder cannot occur.
  • the one above the shaft height tensioned timing belt with two ends is easy to assemble. Because the timing belt is reinforced Has spring properties are not additional Clamping elements in the form of, for example, tension springs Assembly necessary.
  • the ends of the timing belt can be too a thimble and using a bracket with be connected to the toothed belt.
  • the thimble wraps around a cylindrical holder arranged in the shaft. Changes in the structure due to temperature or aging have on the accuracy of the invention Set up no influence because the timing belt always is tense and the level of a particular floor is always on the same tooth of the toothed belt.
  • Fig. 1 shows an elevator system without a machine room.
  • the device according to the invention can also be used for elevator systems can be used with machine room.
  • the elevator drive with traction sheave, over the ropes are an elevator car 2 and a not shown Connect the counterweight and in an elevator shaft 1 and move off.
  • the elevator car 2 is along Guide rails 3 movable.
  • One on one floor arranged elevator control 4 controls the elevator drive and the sequence of movements of the elevator car 2 and ensures the safety of elevator operation.
  • the Elevator car 2 serves floors E1, E2. In the shown An example is an elevator system with two floors shown, there may be more.
  • the security circle the elevator system consists of a series connection of Contacts of the floor doors, not shown, and off an upper and lower limit switch 5.6 of Elevator shaft 1.
  • the upper limit switch 5 prevents Retraction of the elevator car 2 in the shaft head 7
  • the lower limit switch 6 prevents the Elevator car 2 in the shaft pit 8.
  • E1 When entering the Elevator car 2 on one floor E1, E2 becomes one Door zone contact 9 actuates the safety contact of the Floor E1, E2 bridges, making the car door and Floor door can be opened early without the safety circuit is interrupted.
  • the position is Elevator car 2 in elevator shaft 1 is of importance. Therefore is a device for generating shaft information necessary.
  • the encoder 11 arranged on the elevator car 2 has a gear 12, which in the process of Elevator car 2 in elevator shaft 1 by means of the toothed belt 11 can be driven.
  • Guide rollers 13 guarantee the secure engagement of the gear 12 in the toothing of Toothed belt 10.
  • the toothed belt 10 is at each end by means of a cylindrical holder arranged on a cross member 14.
  • the timing belt 10 has spring properties no additional clamping elements in the form, for example of tension springs necessary for assembly.
  • the ends of the Timing belts 10 can each be shaped into a thimble and connected to the toothed belt by means of a clip become.
  • the thimble wraps around the cross member 14 arranged cylindrical holder.
  • the toothed belt 10 has For example, a steel reinforcement on the timing belt 10 gives the spring properties.
  • the Timing belt 10 has a color marking, the one enables twist-free installation right away.
  • the gear 12 of the encoder 11 drives a shaft with a coded disc whose code is read optoelectronically and the data is stored in a shift register become.
  • the code disk rotates by more than 360 ° the coding is repeated.
  • a reduction gear switched that the further code disc in a certain Ratio of rotation to the first code disk slowed down. Further reduction gears and code disks can be downstream.
  • the data exchange with the elevator control 4 takes place such that a clock signal of the elevator control 4 to the Shift register is applied, the clock signal being the serial data transmission to elevator control 4 controls.
  • the elevator control 4 generates from the transmitted data Driving parameters of the elevator car 2 such as the absolute position of the elevator car 2 in the elevator shaft 1, the speed and / or the direction of travel of the Elevator car 2.
  • the position information of the Obtain encoder 11 with the position of the code disks is also used for evacuation operations Encoder 11 operated with battery support. If the encoder 11 no or no valid driving parameters generated, for example, if the toothed belt 10 breaks, the Elevator car stopped immediately.
  • the absolute position information of the encoder 11 can all shaft information not relevant to safety be derived. As can be seen in the example shown, are in addition to the safety switches 5,6,9 Elevator shaft 1 no switches required. For example the level of the floors is determined by means of the encoder 11 measured and communicated to the elevator control 4. This will the elevator car 2 in the elevator shaft 1 on the appropriate levels and the absolute Position information of the floors of the elevator control 4 transfer.
