Definitions

  • the present invention relates to an elevator apparatus As will be described in more detail below, the invention relates more particularly to an elevator apparatus having two cars suspended with 1:1 roping, and more especially to an elevator apparatus provided with a landing correction device for normally landing the two cars at the same time.
  • a known elevator apparatus of a 1:1 roping system is constructed such that cars are connected with opposite ends of a main rope, respectively, which is wrapped around a drive sheave and a deflector wheel installed on an upper portion of a hoistway, as shown in Japanese patent application laid-open No. 2001-240343 for example.
  • the main rope is caused to travel by driving the drive sheave, the other car lands on the bottom floor.
  • the Duo-Lifts adopting the 2:1 roping system, have a complicated structure, and uses the two hydraulic jacks, thus making it impossible to provide cost reduction.
  • JP-A-50114862 discloses an elevator apparatus having two cars suspended from opposite ends of rope or cable, the cable passing over a sheave and being guided around a deflector wheel 6d. Furthermore, a landing correction device serves to pivot the rotational axis of the deflector wheel about the rotational axis of the sheave. In this way, the height position of the car suspended from the deflector wheel would be adjusted slightly relative to the height position of the car suspended from the sheave.
  • an elevator apparatus comprising a drive unit, a first deflector wheel, a hoistway, a first car, a main rope, a second car, in which a sheave of the drive unit and the deflector wheel are arranged at an upper portion of the hoistway, and the first car is connected with a sheave-side end of the main rope, which is suspended from said sheave and said deflector wheel, whereas the second car is connected with a deflector wheel-side end of said main rope suspended from said sheave and said deflector wheel, so that when one of said cars lands on a top floor, the other car lands on a bottom floor, wherein a fixed deflector wheel and a movable deflector wheel are arranged on a path of said main rope between said sheave and said first deflector wheel, and a landing correction device is provided for moving said movable deflector wheel toward and away from said fixed deflector wheel so as to adjust the length of said main rope between said fixed
  • Embodiments of the present invention to be described are intended to obtain an elevator apparatus of a 1:1 roping system which is capable of correcting the landing positions of cars according to an amount of expansion or contraction of a main rope or according to a difference in floor-to-floor distances by the use of a landing correction device, so as to enable both of the cars to land at the same time.
  • Fig. 1 is a vertical cross sectional view that schematically shows the construction of a first form of elevator apparatus.
  • Fig. 2 is a system diagram of the elevator apparatus.
  • Fig. 3 is a flow chart that explains the operation of the elevator apparatus.
  • a drive unit 3 and a deflector wheel 4 are installed in a machine room 2 which is constructed at an upper portion of a hoistway 1, with a main rope 5 being extended or wrapped around a sheave 3a of the drive unit 3 and the deflector wheel 4.
  • a first car 6 is connected with a sheave-side end of the main rope 5, and a second car 7 is connected with a deflector wheel-side end of the main rope 5. Further, it is constructed such that when one of the first car 6 and the second car 7 lands on the top floor, the other car can land the bottom floor.
  • the second car 7 has its chamber or cab 7a mounted on a car frame 7b for vertical movement relative thereto.
  • a pantograph structure 8 is arranged between the floor of the cab 7a or the car frame 7b.
  • a drive motor 9 for driving the pantograph structure 8 in the vertical movement is mounted on the car frame 7b.
  • the pantograph structure 8 and the drive motor 9 together constitute a landing correction device.
  • a call button 10 is installed in an elevator hall or landing place of each floor, and a first position detection switch 11 and a second position detection switch 12 are arranged on an inner wall surface of each floor in the hoistway 1. Also, a first position switch operation cam 13 and a second position switch operation cam 14 are arranged on the first car 6 and the second car 7, respectively. Upon landing of the first car 6 and the second car 7, the first position switch operation cam 13 and the second position switch operation cam 14 operate or actuate a first position detection switch 11 and a second position detection switch 12, respectively.
  • the second position switch operation cam 14 is moved up and down in association with the vertical movement of the cab 7a with respect to the car frame 7b.
  • the main control unit 15 is arranged in the machine room 2, and includes a control part 16 and a memory 17, as shown in Fig. 2 .
  • the main control unit 15 drives the first car 6 and the second car 7 to move in the vertical direction.
  • the drive motor 9 is controlled to be driven to correct the landing position of the second car 7.
  • the control part 16 writes the stop positions of the first and second cars 6, 7 into the memory 17 based on position signals for the first and second cars 6, 7 from the first and second position detection switches 11, 12.
  • the stop positions of the first and second cars 6, 7 stored in the memory 17 are successively updated based on the position signals for the first and second cars 6, 7 from the first and second position detection switches 11, 12.
  • control part 16 monitors car call signals from the call buttons 10 (step 100), so that when a call button 10 is pushed, the floor where a corresponding car call is generated is specified by the control part 16.
  • a car near the car call generation floor is identified from the data of the stop positions of the first and second cars 6, 7 stored in the memory 17, and the drive unit 3 is driven so as to make the nearby car thus identified land on the car call generation floor (step 101).
  • control part 16 determines, from the first position detection switch 11 on a set landing floor of the first car 6, whether the first car 6 has landed on the set landing floor (step 102). When it is determined that the first car 6 has normally landed on the set landing floor, the control part 16 stops the driving operation of the drive unit 3 (step 103).
  • control part 16 performs arithmetic processing so as to determine, based on the data of floor-to-floor distances stored in the memory 17, whether it is necessary to correct the landing position of the second car 7 (step 104).
  • step 104 determines that the correction of the landing position of the second car 7 is unnecessary
  • the control flow moves to step 107, where it is determined, based on the second position detection switch 12 on a set landing floor of the second car 7, whether the second car 7 has landed on the set landing floor.
  • the control part 16 opens the doors of the first and second cars 6, 7.
  • step 107 when it is determined in step 107 that the second car 7 has not landed on the set landing floor, the control flow goes to step 108, where the drive motor 9 is driven to cause the pantograph structure 8 to move up or down, whereby the cab 7a of the second car 7 is moved in the vertical direction.
  • the control part 16 determines, based on the second position detection switch 12 on the set landing floor of the second car 7, whether the second car 7 has landed on the set landing floor (step 109).
  • step 110 the control part 16 stops the driving operation of the drive motor 9 (step 110).
  • the doors of the first and second cars 6, 7 are opened.
  • step 109 When it is determined in step 109 that the second car 7 has not landed on the set landing floor, a return to step 108 is performed.
  • steps 108-110 together constitute a correction step or process for a landing deviation of the second car 7 resulting from a time-varying extension (i.e., extension over time) of the main rope 5 or an expansion or contraction of the main rope 5 due to the load acting thereon.
  • step 104 when it is determined in step 104 that the correction of the landing position of the second car 7 is necessary, the control flow goes to step 105, where an amount of correction of the landing position of the second car 7 is calculated based on the data of floor-to-floor distances stored in the memory 17. Then, the drive motor 9 is driven to operate so that the amount of movement of the pantograph structure 8 is made equal to the amount of correction thus calculated (step 106), and thereafter the control flow goes to step 109.
  • steps 104 through 106 together constitute a correction step or process for a landing deviation of the second car 7 resulting from a difference between floor-to-floor distances or an inequality in floor-to-floor distances.
  • the landing correction device constructed from the pantograph structure 8 and the drive motor 9 is arranged on the second car 7, even if a landing deviation is generated in the second car 7 upon normal landing of the first car 6, the landing deviation of the second car 7 is quickly corrected by means of the landing correction device. Accordingly, the doors of the first and second cars 6, 7 can be made to open at the same time.
  • the elevator apparatus adopts the 1:1 roping system, the structure thereof becomes simple, thus making it possible to reduce the cost of manufacture.
  • the landing correction device is installed on the second car 7 alone, the number of landing correction devices used or required becomes one, and hence the reduction of cost can be accordingly made.
  • control part 16 of the main control unit 15 controls the drive unit 3 in such a manner that the drive unit is driven to make the first car 6 normally land on its set landing floor, and the control part 16 also controls the pantograph structure 8 and the drive motor 9 so that they are driven to make the second car 7 normally land on its set landing floor. Therefore, even if there takes place a time-varying extension of the main rope 5 or an expansion or contraction thereof due to a load applied thereto, the first and second cars 6, 7 can be made to land on the respective floors substantially at the same time without generating any landing deviation, so that they can be opened at the same time.
  • the floor-to-floor distances are stored in the memory 17, and the control part 16 calculates a landing deviation of the second car 7 generated upon normal landing of the first car 6, based on the data of the floor-to-floor distances stored in the memory 17, and controls to drive the pantograph structure 8 and the drive motor 9 so as to correct the calculated amount of landing deviation.
  • the data of floor-to-floor distances stored in the memory 17 may be corrected based on the amount of correction cf the landing deviation obtained in the process of correction of the landing deviation in steps 108 through 110.
  • the data of floor-to-floor distances stored in the memory 17 is updated, so that the generation of a landing deviation of the second car 7 resulting from the expansion or contraction of the main rope 5 can be suppressed.
  • Fig. 4 is a vertical cross sectional view that schematically shows the construction of an elevator apparatus according to a second arrangement.
  • a second car 7A has a cab 7a fixed attached to a car frame 7b, and a landing correction device in the form of an electric winch 20 is arranged at a main rcpe connection portion of the second car 7A.
  • the elevator apparatus operates based on the flow chart shown in Fig. 3 .
  • the control part 16 controls to drive the electric winch 20 so that the winch 20 winds up or draws out the main rope 5 thereby to correct the landing deviation of the second car 7A.
  • the electric winch 20 is used as the landing correction device, and the electric winch 20 is arranged at the main rope connection portion of the second car 7A.
  • the amount of correction of the second car 7A can be increased to accommodate a wide range of landing corrections, and the cab 7a need not be constructed such that it is movable in the vertical direction with respect to the car frame 7b, as in the above-mentioned first embodiment.
  • the second car 7A can be of a simple structure. That is, a car of the same structure as that of the first car 6 can be used for the second car 7A.
  • Fig. 5 is a vertical cross sectional view that schematically shows the construction of an elevator apparatus according to a first embodiment according to the present invention.
  • a fixed deflector wheel 21 is arranged in the machine room 2 at a location close to the deflector wheel 4 with its axis of rotation being in alignment or coincidence with the axis of rotation of the deflector wheel 4.
  • a movable deflector wheel 22 is arranged in the machine room 2 with its axis of rotation being in parallel to the axis of rotation of the fixed deflector wheel 21 so as to be movable toward and away from the fixed deflector wheel 21.
  • a movable deflector wheel driving part in the form of a hydraulic jack 23 is arranged in the machine room 2 so as to move the movable deflector wheel 22 toward or away from the fixed deflector wheel 21.
  • the fixed deflector wheel 21, the movable deflector wheel 22 and the hydraulic jack 23 together constitute a landing correction device.
  • the main rope 5 is connected with the first car 6, ascends therefrom so as to be wrapped around the sheave 3a, and further wrapped sequentially around the fixed deflector wheel 21, the movable deflector wheel 22 and the deflector wheel 4, and descends therefrom to be connected with the second car 7A.
  • the fixed deflector wheel 21 and the movable deflector wheel 22 are arranged on the path of the main rope 5 between the sheave 3a and the deflector wheel 4.
  • the elevator apparatus operates based on the flow chart shown in Fig. 3 .
  • the control part 16 controls the hydraulic jack 23 in such a manner that the hydraulic jack 23 is driven to move the movable deflector wheel 22 so as to approach or separate with respect to the deflector wheel 4 and the fixed deflector wheel 21, whereby the landing deviation of the second car 7A can be corrected.
  • the second car 7A need not have a special structure, and the self weight of the second car 7A becomes lighter, thus making it possible to suppress the generation of the expansion and contraction of the main rope 5 due to the load applied thereto.
  • the pair of the fixed deflector wheel 21 and the movable deflector wheel 22 are arranged on the path of the main rope between the sheave 3a and the deflector wheel 4, so roping ratio is increased, so a wide range of landing correction can be made with a small amount of movement of the movable deflector wheel 22.
  • the number of pairs of the fixed deflector wheel 21 and the movable deflector wheel 22 is one, but a plurality of pairs of fixed deflector wheels 21 and movable deflector wheels 22 may instead be arranged on the main rope path between the sheave 3a and the deflector wheel 4. In this case, the roping ratio can be further increased, and hence it becomes possible to accommodate a much wider range of landing corrections.
  • the movable deflector wheel drive part is not limited to such a hydraulic jack 23 but may instead comprise anything that is capable of moving the movable deflector wheel 22 to approach or separate with respect to the fixed deflector wheel 21.
