Definitions
- the invention relates to a device for generating
- Shaft information in an elevator shaft in which a coded band is arranged above the shaft height, the code of the band being readable by means of a sensor device arranged on an elevator car that can be moved in the elevator shaft and convertible into driving parameters of the elevator car.
- a device for generating shaft information has become known, by means of which the absolute position of the elevator car is determined.
- a stretchable perforated tape stretched over the shaft height is scanned by means of an optical reader arranged on the elevator car.
- the perforated tape has two tracks, one track representing the binary-coded cabin position and the other track having openings at regular intervals over the entire length of the tape.
- One track is scanned by an optical reader, the second track is scanned by two optical readers and the direction of movement of the elevator car is determined from this.
- a disadvantage of the known device is that the belt has to be supported at several points above the shaft height. Another disadvantage is that temperature fluctuations directly affect the accuracy of the
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and of creating a device for generating shaft information using the simplest means.
- the device according to the invention is largely maintenance-free and cannot get dirty and is made up of commercially available parts.
- the device according to the invention does not lose the position information; learning trips after the power failure are not necessary.
- the device replaces all non-safety-relevant shaft switches for generating shaft information.
- the toothed belt which serves as an information transmitter, is in firm engagement with the encoder; slip between the toothed belt and encoder cannot occur.
- the toothed belt with two ends stretched over the shaft height is easy to assemble. Because the toothed belt has a reinforcement with spring properties, no additional tensioning elements in the form of tension springs, for example, are necessary for assembly.
- the ends of the toothed belt can each be shaped into a thimble and connected to the toothed belt by means of a clip.
- the thimble wraps around a cylindrical holder arranged in the shaft. Changes in the structure due to temperature or aging have no influence on the accuracy of the device according to the invention, because the toothed belt is always tensioned and the level of a particular floor is always at the same tooth of the toothed belt.
- Fig. 1 shows a device for generating shaft information.
- Fig. 1 shows an elevator system without a machine room.
- the device according to the invention can also be used for elevator systems with a machine room.
- the elevator car 2 can be moved along guide rails 3.
- An elevator control 4 arranged on one floor controls the elevator drive and the sequence of movements of the elevator car 2 and ensures the safety of the elevator operation.
- the elevator car 2 serves floors E1, E2. In the example shown, an elevator system with two floors is shown, there may be more.
- the safety circuit of the elevator system consists of a series connection of contacts of the floor doors, not shown, and of an upper and lower limit switch 5, 6 of the elevator shaft 1.
- the upper limit switch 5 prevents the elevator car 2 from entering the shaft head 7, and the lower limit switch 6 prevents it from entering the elevator car 2 into the shaft pit 8.
- a door zone contact 9 is actuated, which bridges the safety contact of the floor E1, E2, whereby the car door and
- the device consists of a toothed belt 10 stretched over the shaft height and an encoder 11, which is connected to the toothed belt 10 and detects the absolute position of the elevator car 2.
- the encoder 11 arranged on the elevator car 2 has a gear wheel 12 which can be driven by the toothed belt 11 when the elevator car 2 is moved in the elevator shaft 1.
- Guide rollers 13 guarantee the secure engagement of the gear 12 in the toothing of the
- Toothed belt 10 is arranged at each end by means of a cylindrical holder on a cross member 14. Because the toothed belt 10 has spring properties, no additional tensioning elements in the form of tension springs, for example, are necessary for assembly. The ends of the
- Timing belts 10 can each be shaped into a thimble and connected to the timing belt by means of a clamp.
- the thimble wraps around the cylindrical holder arranged on the cross member 14.
- the toothed belt 10 has, for example, a steel reinforcement that the toothed belt
- the toothed belt 10 gives the spring properties.
- the toothed belt 10 has a color marking that enables twist-free assembly right away.
- a flat belt with a non-slip surface is also possible, which rests on a pulley of the encoder 11 with sufficient pressure.
- the gear wheel 12 of the encoder 11 drives a shaft with an encoded disk, the code of which is read optoelectronically and the data are stored in a shift register.
- the code disk rotates by more than 360 °, the coding is repeated.
- there is a reduction gear between the first and a further code disk switched which slows down the further code disc in a certain ratio to the first code disc. Further reduction gears and code disks can be connected downstream.
- the data exchange with the elevator control 4 takes place in such a way that a clock signal of the elevator control 4 is applied to the shift register, the clock signal controlling the serial data transmission to the elevator control 4.
- the elevator control 4 From the transmitted data, the elevator control 4 generates driving parameters of the elevator car 2, such as, for example, 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 encoder 11 is retained with the position of the code disks. Because the device for generating shaft information is also used for evacuation operations, the encoder 11 is operated with the aid of batteries. If the encoder 11 generates no or no valid travel parameters, for example if the toothed belt 10 breaks, the elevator car is stopped immediately.
