Definitions

  • the present invention relates to a termination floor forced deceleration device of an elevator.
  • a buffer for preventing the collision of a car or a counterweight is provided in a pit in a bottom portion of a shaft.
  • This buffer is required to have a stroke such that the car or the like is buffered sufficiently even when colliding with the buffer at full speed.
  • This required stroke becomes longer with the increase in the rated speed of elevator. Therefore, there arises a need for increasing the depth of the pit in which the buffer is installed as the rated speed of elevator increases.
  • the pit depth has been decreased by making the stroke of the buffer shorter than the inherently required length, and there has often been provided a device (termination floor forced deceleration device) for decelerating the car or the like before colliding with the buffer.

  • These first lower position detection sensor (BTA) 15a and second lower position detection sensor (BTB) 15b are arranged side by side along the rising/lowering direction of the car 4 at a predetermined interval.
  • the first lower position detection sensor (BTA) 15a is arranged so as to be positioned on the lower terminal side of the shaft 1 with respect to the second lower position detection sensor (BTB) 15b.

  • the car 4 is mounted with a shielding plate 17 facing to these position detection sensors.
  • the configuration is made such that when the car 4 comes to the predetermined lower terminal position, the shielding plate 17 of the car 4 shields both of the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b. Also, the configuration is made such that when the car 4 comes to the predetermined upper terminal position, the shielding plate 17 of the car 4 shields both of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b.
  • position detection sensors are of noncontact type. At the ordinary time, that is, at the time when the sensor part of the position detection sensor is not shielded by the shielding plate 17, the voltage (potential) is in a relatively high state. Also, the position detection sensor whose sensor part is shielded by the shielding plate 17 of the car 4 is in a state in which the voltage (potential) is relatively low. In the description below, in some cases, the state in which the voltage (potential) is relatively high is represented as a (signal) delivered state, and the state in which the voltage (potential) is relatively low is represented as a delivery shut-off state.
  • a lower position detection sensor consistency check circuit 18 and an upper position detection sensor consistency check circuit 19 are provided.
  • the lower position detection sensor consistency check circuit 18 checks the coordination of the output results of the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b.

  • the upper position detection sensor consistency check circuit 19 checks the coordination of the output results of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b.

If it is recognized that the car 4 lies on the terminal side of the respective terminal position, when the overspeed monitoring section 14b judges that the speed of the car 4 is a preset predetermined speed or higher on the basis of the speed detection signal 11a, the overspeed monitoring section 14b outputs a braking instruction to the operation control section 14a so that the car 4 is compulsorily stopped or decelerated. The operation control section 14a to which this braking instruction has been given controls the brake 6b to stop or decelerate the car 4.
  • the speed at which the car 4 is decelerated compulsorily when the car 4 lies on the lower terminal side of the lower terminal position and the speed at which the car 4 is decelerated compulsorily when the car 4 lies on the upper terminal side of the upper terminal position can be set at different and separate values.

  • the elevator equipped with the termination floor forced deceleration device configured as described above operates following the flow shown in Figure 7 explained later.
  • Figure 2 shows the operation states of the lower position detection sensor consistency check circuit 18 and the upper position detection sensor consistency check circuit 19 in the case where after the power source has been turned on in the state in which the car 4 lies on the bottom floor, the car 4 is first run to the top floor, next being run to the bottom floor, and thereafter is run again to the top floor.
  • the car 4 when the car 4 lies on the bottom floor, the car 4 is located at a position lower than the predetermined lower terminal position. Therefore, all of the position detection sensors, that is, all of the first lower position detection sensor (BTA) 15a, the second lower position detection sensor (BTB) 15b, the first upper position detection sensor (TPA) 16a, and the second upper position detection sensor (TPB) 16b are not shielded by the shielding plate 17 of the car 4. Therefore, signals are delivered from all of the position detection sensors.
  • the first lower-side relay (LWA) 20a and the second lower-side relay (LWB) 20b are in a released (not-energized) state.
  • the first lower-side normally closed contact 23a and the second lower-side normally closed contact 23b between the first upper position detection sensor (TPA) 16a and the third lower-side relay (LWC) 20c and between the second upper position detection sensor (TPB) 16b and the third lower-side relay (LWC) 20c are closed, so that the third lower-side relay (LWC) 20c is in an energized state.
  • the first upper-side relay (UPA) 21a and the second upper-side relay (UPB) 21b are in a released (not-energized) state.
  • the first upper-side normally closed contact 25a and the second upper-side normally closed contact 25b between the first upper position detection sensor (TPA) 16a and the third upper-side relay (UPC) 21c and between the second upper position detection sensor (TPB) 16b and the third upper-side relay (UPC) 21c are closed, so that the third upper-side relay (UPC) 21c is in an energized state.
  • the first lower-side normally opened contact 22a and the second lower-side normally opened contact 22b are opened, and the third lower-side normally closed contact 23c is also opened, so that the output from the lower position detection sensor consistency check circuit 18 to the overspeed monitoring section 14b is shut off.
  • the first upper-side normally opened contact 24a and the second upper-side normally opened contact 24b are opened, and the third upper-side normally closed contact 25c is also opened, so that the output from the upper position detection sensor consistency check circuit 19 to the overspeed monitoring section 14b is also shut off. Therefore, since the state is such that no output is delivered from either of the lower position detection sensor consistency check circuit 18 and the upper position detection sensor consistency check circuit 19, in the overspeed monitoring section 14b, the detection of position of the car 4 is in an indefinite state.
  • the shielding plate 17 of the car 4 shields the first lower position detection sensor (BTA) 15a, and the output from the first lower position detection sensor (BTA) 15a is shut off.
  • the shielding plate 17 shields the second lower position detection sensor (BTB) 15b, and both of the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b become in a state of being shielded by the shielding plate 17.
  • the car 4 lies at the predetermined lower terminal position, and the outputs from both of the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b are shut off.
  • the shielding plate 17 comes to not shield the first lower position detection sensor (BTA) 15a, and the output from the first lower position detection sensor (BTA) 15a is restarted. Since the third lower-side relay (LWC) 20c is energized, and the third lower-side normally opened contact 22c is closed, when the output from the first lower position detection sensor (BTA) 15a is restarted, the first lower-side relay (LWA) 20a is energized. When the first lower-side relay (LWA) 20a is energized, the first lower-side normally opened contact 22a in the lower position detection sensor consistency check circuit 18 is closed, and the first lower-side normally closed contact 23a therein is opened. Therefore, the first lower-side relay (LWA) 20a becomes in a self-held state.
  • the shielding plate 17 comes to not shield the second lower position detection sensor (BTB) 15b as well, and the output from the second lower position detection sensor (BTB) 15b is also restarted. Since the third lower-side relay (LWC) 20c is energized, and the third lower-side normally opened contact 22c is closed, when the output from the second lower position detection sensor (BTB) 15b is restarted, the second lower-side relay (LWB) 20b is energized. When the second lower-side relay (LWB) 20b is energized, the second lower-side normally opened contact 22b in the lower position detection sensor consistency check circuit 18 is closed, and the second lower-side normally closed contact 23b therein is opened. Therefore, the second lower-side relay (LWB) 20b also becomes in a self-held state.
  • the third lower-side relay (LWC) 20c When the second lower-side normally closed contact 23b is opened, the third lower-side relay (LWC) 20c is released.
  • the third lower-side relay (LWC) 20c When the third lower-side relay (LWC) 20c is released, the third lower-side normally opened contact 22c in the lower position detection sensor consistency check circuit 18 is opened, and the third lower-side normally closed contact 23c therein is closed. Therefore, the first lower-side normally opened contact 22a and the second lower-side normally opened contact 22b are closed, and the third lower-side normally closed contact 23c is also closed, so that a state is established in which a signal is delivered from the lower position detection sensor consistency check circuit 18 to the overspeed monitoring section 14b (the voltage is high).
  • the overspeed monitoring section 14b can recognize that the car 4 has gone up and separated from the lower terminal position.
  • a state is established in which the output from the lower position detection sensor consistency check circuit 18 is present, and on the other hand, the output from the upper position detection sensor consistency check circuit 19 is absent. Based on this state of output, the overspeed monitoring section 14b recognizes that the car 4 lies at the upper terminal position.
  • the shielding plate 17 of the car 4 first shields the second upper position detection sensor (TPB) 16b, and next shields the first upper position detection sensor (TPA) 16a, so that a state is established in which both of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b are shielded by the shielding plate 17.
  • the car 4 lies at the predetermined upper terminal position, and the outputs from both of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b are shut off.

  • the shielding plate 17 comes to not shield the second upper position detection sensor (TPB) 16b, and the output from the second upper position detection sensor (TPB) 16b is restarted. Since, in this state, the third upper-side relay (UPC) 21c is energized, and the third upper-side normally opened contact 24c is closed, when the output from the second upper position detection sensor (TPB) 16b is restarted, the second upper-side relay (UPB) 21b is energized. When the second upper-side relay (UPB) 21b is energized, the second upper-side normally opened contact 24b is closed, and the second upper-side relay (UPB) 21b is self-held. Also, the second upper-side normally closed contact 25b is opened, and the third upper-side relay (UPC) 21c is released.
  • the shielding plate 17 comes to not shield the first upper position detection sensor (TPA) 16a as well, and the output from the first upper position detection sensor (TPA) 16a is restarted. Since the third upper-side relay (UPC) 21c has already been released, even if the output from the first upper position detection sensor (TPA) 16a is restarted, the first upper-side relay (UPA) 21a is not energized and is still released. Therefore, the output from the upper position detection sensor consistency check circuit 19 to the overspeed monitoring section 14b is still shut off.
  • the shielding plate 17 of the car 4 shields the first upper position detection sensor (TPA) 16a, and the output from the first upper position detection sensor (TPA) 16a is shut off. Then, the shielding plate 17 shields the second upper position detection sensor (TPB) 16b, and both of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b become in a state of being shielded by the shielding plate 17. In this state, the car 4 lies at the predetermined upper terminal position, and the outputs from both of the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b are shut off.
  • the second upper-side relay (UPB) 21b As the output from the second upper position detection sensor (TPB) 16b has been shut off, the second upper-side relay (UPB) 21b is released. When the second upper-side relay (UPB) 21b is released, the second upper-side normally closed contact 25b is closed, so that the third upper-side relay (UPC) 21c is energized.
  • the shielding plate 17 comes to not shield the first upper position detection sensor (TPA) 16a, and the output from the first upper position detection sensor (TPA) 16a is restarted. Since the third upper-side relay (UPC) 21c is energized, and the third upper-side normally opened contact 24c is closed, when the output from the first upper position detection sensor (TPA) 16a is restarted, the first upper-side relay (UPA) 21a is energized. When first upper-side relay (UPA) 21a is energized, the first upper-side normally opened contact 24a is closed, and the first upper-side normally closed contact 25a is opened. Therefore, the first upper-side relay (UPA) 21a becomes in a self-held state.
  • the shielding plate 17 comes to not shield the second upper position detection sensor (TPB) 16b as well, and the output from the second upper position detection sensor (TPB) 16b is also restarted. Since the third upper-side relay (UPC) 21c is energized, and the third upper-side normally opened contact 24c is closed, when the output from the second upper position detection sensor (TPB) 16b is restarted, the second upper-side relay (UPB) 21b is energized.

  • the overspeed monitoring section 14b recognizes that the car 4 lies at an intermediate position between the upper and lower terminal positions.
  • the overspeed monitoring section 14b recognizes that the car 4 lies at the upper terminal position.

  • Step S4 the operation control section 14a checks whether or not the car 4 stops at the bottom floor. If the car 4 stops at the bottom floor, the process proceeds to Step S5, where the operation control section 14a runs the car 4 to the top floor at the buffer corresponding speed. In the successive Step S6, the operation control section 14a checks whether or not the car call or the hall call has been registered.
  • Step S7 If the car call or the hall call has not been registered in Step S6, in Step S7, the operation control section 14a runs the car 4 to the bottom floor at the buffer corresponding speed, and thereafter, in Step S8, the highest speed is set at the rated speed, and a series of processing is finished. On the other hand, if the car call or the hall call has been registered in Step S6, in Step S9, the operation control section 14a runs the car 4 in response to the call having been registered.
  • Step S10 the operation control section 14a checks whether or not the car 4 stops at the bottom floor. If the car 4 stops at the bottom floor, the process proceeds to Step S8, where the highest speed is set at the rated speed, and a series of processing is finished. On the other hand, if the car 4 does not stop at the bottom floor, the process returns to Step S6.
  • Step S11 the operation control section 14a checks whether or not the car 4 stops at the top floor. If the car 4 does not stop at the top floor, in Step S12, the operation control section 14a checks whether or not the car 4 stops at an intermediate floor.

  • Step S13 the operation control section 14a runs the car 4 to the bottom floor at the buffer corresponding speed.
  • Step S14 the operation control section 14a checks whether or not the car call or the hall call has been registered. If the car call or the hall call has not been registered in Step S14, in Step S15, the operation control section 14a runs the car 4 to the top floor at the buffer corresponding speed, and thereafter, in Step S8, the highest speed is set at the rated speed, and a series of processing is finished.
  • Step S16 the operation control section 14a runs the car 4 in response to the call having been registered.
  • Step S17 the operation control section 14a checks whether or not the car 4 stops at the top floor. If the car 4 stops at the top floor, the process proceeds to Step S8, where the highest speed is set at the rated speed, and a series of processing is finished.

  • the termination floor forced deceleration device in accordance with this embodiment is configured so that the two position detection sensors are provided at each of the lower terminal and the upper terminal, and the outputs of these position detection sensors are delivered to the overspeed monitoring section 14b via the consistency check circuit, whereby it is recognized whether or not the car 4 lies at the predetermined terminal position.
  • Figures 4 to 7 show the operations of the lower position detection sensor consistency check circuit 18 and the upper position detection sensor consistency check circuit 19 in the case where an abnormality occurs in either one of the two position detection sensors provided on the same terminal side in the termination floor forced deceleration device configured as described above.
  • Figure 4 shows the case where an ON failure, that is, a failure such that a signal is delivered continuously at all times occurs in the first lower position detection sensor (BTA) 15a of the two lower position detection sensors.
  • BTA first lower position detection sensor
  • the shielding plate 17 of the car 4 first shields the second lower position detection sensor (BTB) 15b. Thereby, the output from the second lower position detection sensor (BTB) 15b is shut off, and the second lower-side relay (LWB) 20b having been energized is released.
  • the second lower-side relay (LWB) 20b is released, the second lower-side normally opened contact 22b is opened, so that the output from the lower position detection sensor consistency check circuit 18 to the overspeed monitoring section 14b is shut off.
  • the car 4 arrives at the predetermined lower terminal position, and the first lower position detection sensor (BTA) 15a is also shielded by the shielding plate 17.
  • the first lower position detection sensor (BTA) 15a ON-fails, the output from the first lower position detection sensor (BTA) 15a is continued without being shut off.
  • the first lower-side relay (LWA) 20a is kept in an energized state. Therefore, the first lower-side normally closed contact 23a is still open, and the third lower-side relay (LWC) 20c is not energized.
  • the first lower position detection sensor (BTA) 15a ON-fails, when the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b are shielded by the shielding plate 17, the first lower-side relay (LWA) 20a is still in an energized state, and the second lower-side relay (LWB) 20b and the third lower-side relay (LWC) 20c become in a not-energized state.
  • This situation is the same also when the car 4 goes up from the bottom floor and passes through the lower terminal position. Therefore, even when the car 4 goes up from the bottom floor and passes through the lower terminal position, no signal is delivered from the lower position detection sensor consistency check circuit 18.
  • the overspeed monitoring section 14b can recognize that the car 4 lies at the lower terminal position. However, even when the car 4 goes up from the bottom floor and passes through the lower terminal position, no signal is delivered from the lower position detection sensor consistency check circuit 18, so that the overspeed monitoring section 14b still recognizes that the car 4 lies at the lower terminal position.
  • This state means that the position of the car 4 is mistakenly recognized by the overspeed monitoring section 14b. However, this mistaken recognition is not on the danger side but on the safety side. That is, the state in which the highest speed of elevator is set at the buffer corresponding speed lower than the rated speed continues, so that the safety can be ensured.
  • FIG 5 shows the case where an ON failure occurs in the second lower position detection sensor (BTB) 15b of the two lower position detection sensors.
  • BTB second lower position detection sensor
  • the overspeed monitoring section 14b can recognize that the car 4 lies at the lower terminal position. Even when the car 4 goes up from the bottom floor and passes through the lower terminal position, no signal is delivered from the lower position detection sensor consistency check circuit 18, so that the overspeed monitoring section 14b still recognizes that the car 4 lies at the lower terminal position.
  • Figure 6 shows the case where an OFF failure, that is, a failure such that no signal is delivered occurs in the first lower position detection sensor (BTA) 15a of the two lower position detection sensors.
  • BTA first lower position detection sensor
  • the shielding plate 17 of the car 4 first shields the second lower position detection sensor (BTB) 15b. Thereby, the output from the second lower position detection sensor (BTB) 15b is shut off, and the second lower-side relay (LWB) 20b having been energized is released.
  • the second lower-side relay (LWB) 20b is released, the second lower-side normally opened contact 22b is opened, so that the output from the lower position detection sensor consistency check circuit 18 to the overspeed monitoring section 14b is shut off.
  • the output from the first lower position detection sensor (BTA) 15a is also shut off.
  • the first lower-side relay (LWA) 20a having been energized is released.
  • the first lower-side relay (LWA) 20a is released, the first lower-side normally closed contact 23a is closed, so that the third lower-side relay (LWC) 20c is energized.
  • the second lower position detection sensor (BTB) 15b and the first lower position detection sensor (BTA) 15a come to be not shielded by the shielding plate 17.
  • the output from the second lower position detection sensor (BTB) 15b is restarted, but because the first lower position detection sensor (BTA) 15a has OFF-failed, the output from the first lower position detection sensor (BTA) 15a is not restarted thereafter.
  • the first lower position detection sensor (BTA) 15a OFF-fails, the first lower-side relay (LWA) 20a is not energized. Therefore, the first lower-side normally opened contact 22a is still opened, so that even when the car 4 goes up from the bottom floor and passes through the lower terminal position, no signal is delivered from the lower position detection sensor consistency check circuit 18.
  • the overspeed monitoring section 14b can recognize that the car 4 lies at the lower terminal position. Even when the car 4 goes up from the bottom floor and passes through the lower terminal position, no signal is delivered from the lower position detection sensor consistency check circuit 18, so that the overspeed monitoring section 14b still recognizes that the car 4 lies at the lower terminal position. Therefore, since the position of the car 4 is recognized on the safety side, as in the above-described case of ON failure, it can be recognized, while the safety is ensured, that the car 4 has gone down to the predetermined lower terminal position.
  • the overspeed monitoring section 14b outputs a braking instruction for decelerating the car 4.
  • the two position detection sensors (the first lower position detection sensor (BTA) 15a and the second lower position detection sensor (BTB) 15b, or the first upper position detection sensor (TPA) 16a and the second upper position detection sensor (TPB) 16b) for detecting the shielding plate 17, which is an actuation plate provided on the car 4, are arranged side by side along the rising/lowering path of the car 4 in the shaft 1.
  • the device is provided with the consistency check circuit that reverses the output from itself based on the outputs of both of the two position detection sensors when the outputs of both of the two position detection sensors are consistent with each other, and based on the output from the consistency check circuit, the overspeed monitoring section 14b recognizes whether or not the car 4 lies at a position within the predetermined distance from the terminal of the shaft 1.
  • the state in which the outputs of both of the two position detection sensors are consistent with each other is a state in which, for example, as shown in Figure 2 , if the output from one of the both is shut off, the output from the other is successively shut off, and if the output from one of the both is restarted, the output from the other is successively restarted.
  • the outputs from the both are consistent with each other as described above, the output from the consistency check circuit itself is reversed, that is, when a signal is delivered from the consistency check circuit, this output is shut off, and when the output from the consistency check circuit is shut off, the output is restarted.
  • the consistency check circuit delivers an output telling that the consistency check circuit has detected the actuation plate from at least one of both of the two position detection sensors, and when the outputs of both of the two position detection sensors are not consistent with each other, the output such that the overspeed monitoring section 14b recognizes that the car 4 lies at a position within the predetermined distance from the terminal of the shaft 1 is produced, that is, the output is shut off.
  • the state in which the outputs of both of the two position detection sensors are not consistent with each other is a state in which the output from one of the both is not shut off although the output from the other is shut off, for example, as shown in Figures 4 to 7 , or a state in which inversely the output from one of the both is not restarted although the output from the other is restarted.
  • the output from the consistency check circuit is shut off, and the overspeed monitoring section 14b recognizes that the car 4 lies at the upper or lower terminal position.
  • Figure 8 relates to a second embodiment of the present invention, being a schematic general view for explaining the entire configuration of a termination floor forced deceleration device of an elevator.
  • the position detection sensor consistency check circuit in order to set the operation state of the position detection sensor consistency check circuit when the power source is turned on, it is necessary to operate the car once from the terminal floor to the opposite-side terminal floor and to shield all of the position detection sensors once by the shielding plate, as described above. This is the same when the power is restored after the power source has been shut off by power failure or the like. That is, if the power source is shut off by power failure or the like, the energization of all of the relays of the position detection sensor consistency check circuits is released. When the power is restored, the position of the car cannot be recognized normally unless the car is operated once from the terminal floor to the opposite-side terminal floor.
  • a battery is provided to hold the operation states of relays in the position detection sensor consistency check circuits just before the power source is shut off when the power source is shut off by power failure or the like.
  • a battery 26 is connected to the lower position detection sensor consistency check circuit 18 and the upper position detection sensor consistency check circuit 19. If the power source is shut off by power failure or the like, the power is supplied from this battery 26 to these position detection sensor consistency check circuits. By the power supplied from the battery 26, the operation (energization) of the relays of the position detection sensor consistency check circuits is held.
  • the same effect as that of the first embodiment can be achieved, and additionally, even if the power source is shut off by power failure or the like, the operation states of the relays in the position detection sensor consistency check circuits can be held. Also, the position of the car can be recognized normally without operating the car once from the terminal floor to the opposite-side terminal floor when the power is restored.
  • the present invention can be utilized in the termination floor forced deceleration device of an elevator, which has an overspeed monitoring section that outputs a braking instruction for decelerating a car when the speed of the car lying at a position within a predetermined distance from the shaft terminal reaches a preset predetermined speed.
