Definitions

  • the present invention relates to a multi-car elevator having a plurality of cages every shaft, and is particular suited to a degraded operation of the remaining cages when one cage fails.
  • a multi-car elevator according to the preamble portion of patent claim 1 is known from US-A-4511017 .
  • a circulating type multi-car elevator in which upper and lower portions of two shafts are connected to constitute a circulatory path and a plurality of cages move circulatingly, such as described in JP-A-2006-111408 .
  • the circulating type multi-car elevator described in JP-A-2006-111408 can move to one shaft from another at the highest floor and the lowest floor.
  • degraded operation is performed withdrawing a cage having failed to an upper or lower floor as shown in JP-A-6-263361 , however, the other normally operating cages can not move to one shaft from another at upper or lower regions.
  • a single cage can not transport a passenger to all floors in the same manner as a double deck elevator, of which a cage is two-storied, or a one-shaft multi-car elevator with a plurality of cages in a single shaft.
  • a multi-car elevator composed of two or more shafts and having a plurality of cages moving in the same shaft vertically, the multi-car elevator comprising: failure detecting means that detects failure in the cages and a position in which failure is caused and operating mode switching means for switchover to degraded operation for service of a cage in which failure is not detected, in the case where failure is detected.
  • US-A-5719360 discloses a multi-car elevator system for servicing a plurality of floors in a building which includes a plurality of elevator cars for servicing selected floors of the building, a controller for dispatching the plurality of elevator cars; input means for providing a transfer floor position signal to the controller; and an adjustable transfer floor for facilitating transfer of passengers between the plurality of elevator cars, wherein the controller adjusts the location of the adjustable transfer floor in response to the transfer floor position signal.
  • a control device 1 operates two cages 3a, 3c present in a left shaft 2L and a single cage 3b present in a right shaft 2R.
  • Hall call buttons 4 for calling of an elevator are mounted on respective floors and each respective cage 3 is provided with a cage call button 5, with which a passenger designates an end floor.
  • the control device 1 includes a failure detecting unit 6, an operating mode switching unit 7, a cage assigned hall call registering unit 8, a cage call registering unit 9, a cage assigned hall call registering unit 10 in degraded operation, a cage stop floor assigning unit 11, a path searching unit 12, a transfer floor registering unit 13, a transfer cage transfer floor registering unit 14, a transfer cage end floor registering unit 15, and a cage call registering unit 16.
  • the control device 1 issues a command to a cage control device 17 for each of the cages 3 to operate each of the cages 3.
  • the cage assigned hall call registering unit 8 assigns a cage 1, which answers a hall call, out of all the cages 3a to 3c.
  • the control device 1 registers a destined floor in the corresponding cage control device 17 and assigns a cage 3 to that floor which makes a call.
  • the cage call registering unit 9 registers an end floor as a destined floor in the cage control device 17. The cage 3 successively stops at the destined floors registered in the cage control device 17.
  • the failure detecting unit detects failure of a cage 3 and a position thereof according to safety signals given by the respective cages 3 and by the use of a position detecting device (not shown).
  • the safety signals are given when various safety devices such as emergency stops of the cages 3 or the like act.
  • positions of cages 3 are detected by an encoder mounted to a drive motor.
  • the operating mode switching unit 7 When the failure detecting unit 6 detects a cage 3 in a stoppage state by failure, etc., the operating mode switching unit 7 performs switchover to degraded operation.
  • the first cage 3a is present in a lower region of the left shaft 2L
  • the second cage 3b is present in the right shaft 2R
  • the third cage 3c fails above the first cage 3a.
  • the cage stop floor assigning unit 11 determines those floors, at which the respective cages 3 should stop, according to a position of the failure cage 3c to assign the cages to the floors. In the embodiment, let assume that the third cage 3c fails between a fourth floor and a fifth floor.
  • the failure cage 3c cannot stop anywhere, no stop floor is assigned thereto. Since the first cage 3a present below the failure cage 3c can move to a third floor from a first floor, the first to third floors are assigned as stop floors. Since there is no obstacle to the second cage 3b present in the right shaft 2R, the first to sixth floors, which are the same as those in normal operation, are assigned as stop floors.
  • the cage assigned hall call registering unit 10 refers to stop floors assigned to the respective cages 3 to make those cage, to which the first floor is assigned as a stop floor, candidates for cage assignment.
  • the first cage 3a and the second cage 3b make candidates and the first cage 3a, which is positioned close to the first floor and for which waiting time is short, is assigned.
  • cage assignment is determined, a destined floor is registered in the corresponding cage control device 17 in the same manner as in normal operation.
  • the path searching unit 12 refers to a stop floor assigned to the first cage 3a to determine that the first cage 3a can stop at the second floor.
  • the cage call registering unit 16 registers an end floor as a destined floor of the first cage 3a.
  • an end floor indicated by the cage call button 5a in the first cage 3a is the fifth floor. Since stop floors assigned to the first cage 3a are the first to third floors, the path searching unit 12 determinates that transfer is necessary. That cage 3, which is common to the first cage 3a with respect to a stop floor and in which a stop floor is assigned to an end floor, is searched. That is, the second cage 3b corresponds to this. Subsequently, in view of an efficiency, a transfer floor is determined out of those stop floors, which are common to the first cage 3a and the second cage 3b.
  • a first method of determining a transfer floor comprises first calculating an estimated period of time elapsed for movement of the first cage 3a until it reaches a candidate floor for transfer, and an estimated period of time elapsed for movement of the second cage 3b until it reaches a candidate floor for transfer. A comparison is made between the both estimated periods of time and a floor having a minimum time difference is set as a transfer floor.
  • a second method of determining a transfer floor comprises determining a transfer floor taking preference of a total period of time for movement to an end floor from a starting floor, to a waiting time at the time of transfer.
  • a waiting time at the time of transfer is not necessarily shortest but it is possible to reach an end floor in a shortest period of time.
  • the path searching unit 12 determinates a transfer floor according to any one of the measures described above.
  • the transfer floor registering unit 13 sets a transfer floor as a destined floor of the first cage 3a in a cage control device 17a of the first cage 3a.
  • the transfer cage transfer floor registering unit 14 registers a transfer floor as a destined floor in a cage control device 17b of the second cage 3b and the transfer cage end floor registering unit 15 registers a destined floor in the cage control device 17b of the second cage 3b, so that after the second cage 3b stops at the transfer floor, it moves to the end floor.
  • a transfer floor is indicated together with a destined floor in the cage 3a.
  • guidance for transfer is preferably made by a voice at the time of stoppage at a transfer floor.
  • a destined floor may be indicated or guided by a voice. It suffices to light up a button of an end floor on the cage call button 5b in the second cage 3b to show that registration is over.
  • the second cage 3b opens a door and closes the door after the lapse of a certain period of time to move to an end floor.
  • a plurality of pulleys 18 are arranged top and bottom in a circular manner to constitute a circulating rope 19, and two set of circulating ropes 19F, 19R are arranged in front and in rear relative to a cage 3.
  • Two rope clamping portions 20F, 20R are mounted on a diagonal on an upper portion of the cage 3, and the cage 3 is fixed to the forward and rearward circulating ropes 19F, 19R.
  • forward and rearward circulating ropes 19F, 19R are depicted by a single line in Fig. 2 , they actually comprise a plurality of circulating ropes 19F, 19R.
  • the respective cages 3, respectively, are fixed to different circulating ropes 19F, 19R.
  • Two cages 3 are fixed in opposite positions on the circulating rope 19 so that mating cages mutually serve as a balancing weight to cancel dead loads of the cages 3.
  • Upper drive pulleys 18U are arranged offset in front and in rear to have the different circulating ropes 19 wound thereround. Respective drive motors 21 move the respective drive pulleys 18U whereby the respective circulating ropes 19 are moved individually. Consequently, it is possible to drive the plurality of cages 3 independently.
  • the cages 3 While being fixed to the circulating ropes 19, the cages 3 transfer to an adjacent shaft 2 in reversal regions on highest and lowest portions to move circulatingly.
  • a configuration in which no reversal regions are provided top and bottom, provides an opposed cage balance type one-shaft multi-car elevator.
  • the circulating type multi-car elevator will be described with respect to degraded operation in the event of failure.
  • a mating cage 3b is fixed to the same rope to which the first cage 3a is fixed, and is constructionally sure to stop at the same intermediate floor M. Accordingly, assuming that the mating cage 3b is a second cage 3b, the cages surely reach the intermediate floor M at the same time, so that transfer can be smoothly made. Accordingly, the path searching unit 12 does not need to calculate an estimated period of time for movement, but it suffices to set a transfer floor to the intermediate floor M.
  • Fig. 3 shows an example of movement to a B floor above a C floor, at which a cage 3c in failure stops, from a lowest floor A.
  • a plurality of cages 3 may be withdrawn above or below an intermediate floor in a lump.
  • a cage 3 moving to the intermediate floor M from the lowest floor in the left shaft 2L may be left and other cages 3 may be withdrawn above the intermediate floor M in the left shaft 2L.
  • cages 3 coupled to the same rope collect below the intermediate floor M in the right shaft 2R.
  • the first cage 3a serves in a state, in which an obstructive cage or cages 3 are absent from the lowest floor to the intermediate floor M in the left shaft 2L, and likewise the second cage 3b serves from the intermediate floor M to the highest floor in the right shaft 2R.
  • a further elevator 22 serving at intermediate floors is arranged to enable transfer.
  • Fig. 3 shows an example, in which a shuttle elevator 22 is provided in combination. Doors 23 are provided even at intermediate floors, at which the shuttle elevator 22 does not stop, and a cage 3i of the shuttle elevator 22 is enabled to stop at these floors in degraded operation.
  • the shuttle elevator 22 is provided with three doors 23 so as to enable stopping at three floors, that is, the intermediate floor M and floors just above and just below the intermediate floor.
  • those floors, at which the circulating type multi-car elevator is impossible to stop include three floors, that is, the intermediate floor M and floors just above and just below the intermediate floor. Accordingly, a fifth floor is made an intermediate floor, at which the elevator 22 such as a shuttle elevator or the like should serve.
  • a multi-car elevator 24L in a lower zone is arranged to overlap the lowest floor over two floors and a multicar elevator 24U in an upper zone is arranged to overlap the highest floor over two floors.
  • multi-car elevators 24 in further zones overlap the multi-car elevator over three floors.
  • FIG. 4 shows an example of getting into a cage 3a in a left shaft 2L from a lowest floor A to move to the intermediate floor M1 and transferring to a second cage 2f, which is coupled to a different rope, in a right shaft 2R to move to the same floor as that of a cage 3c, which has failed at a B floor.
  • a mating cage 1b coupled to the same rope as that of the first cage 3a and a mating cage 3e coupled to the same rope as that of the second cage 2f move to the intermediate floor M2 at the time of transfer. This is because two cages 3 coupled to the same rope stand in a symmetrical, positional relationship at all times.
  • a transfer floor is set to a floor distant one or more floors from the two intermediate floors and a second cage 3f coupled to a different rope from that of the first cage 3a is caused to stop at the same transfer floor as that, at which the first cage stops.
  • a further elevator 22 serving at intermediate floors is arranged.
  • transfer to the shuttle elevator 22 can be made.
  • the shuttle elevator 22 is provided with four doors 23 so as to enable stopping at four floors, that is, the intermediate floors M1, M2 and floors just above and just below the intermediate floors.
  • emergency elevators are provided in plural
  • operating modes of a part of the emergency elevators may be switched over in degraded operation so as to preferentially serve floors, which a multi-car elevator 24M in failure serve.
  • a multi-car elevator 24M in failure serve.
