A landing door 13 is provided at each of the landings on multiple floors. Each landing door 13 opens and closes in conjunction with the car door 12 when the car 8 lands on the floor.

At the bottom of the cage 8, an adsorbent use container 21 is attached. The adsorbent use container 21 is arranged below the cage 11. That is, the adsorbent use container 21 is placed outside the car compartment 11.

FIG. 2 is a side view showing essential parts of the elevator shown in FIG. 1. In the first embodiment, the counterweight 9 faces the back surface of the car chamber 11 when located at the same height as the car 8. That is, the lifting area of the counterweight 9 is located behind the lifting area of the car 8 when viewed from the landing.

The car frame 10 has an upper beam 10a, a pair of vertical columns 10b, and a lower beam 10c. The upper beam 10a is horizontally fixed between the upper ends of a pair of vertical columns 10b. A first end of the suspension body 7 is connected to the upper beam 10a.

The lower beam 10c is horizontally fixed between a pair of vertical columns 10b below the upper beam 10a. The cage 11 is supported on a lower beam 10c below the upper beam 10a. Moreover, the cage 11 is located between a pair of vertical columns 10b.

Although not shown in FIG. 1, the car compartment 11 is provided with a car sill 14 and an apron 15. The car sill 14 is provided at the lower front of the car compartment 11. Further, the car sill 14 guides the lower end of the car door 12 during opening and closing operations of the car door 12.

The adsorbent use container 21 is supported by the lower beam 10c via a pair of support arms 16. In FIG. 2, only one of the pair of support arms 16 is shown. In addition, in FIG. 2, a cross section of the adsorbent use container 21 is shown.

Further, the adsorbent use container 21 is arranged below the lower beam 10c with a space between it and the lower beam 10c. Thereby, a ventilation path is secured between the lower part of the car room 11 and the adsorbent use container 21.

The adsorbent use container 21 has a use container main body 21a and a flat use container lid 21b. The container main body 21a has air permeability. As the basket 8 moves downward, an upward airflow is generated within the container main body 21a.

A carbon dioxide adsorbent 31 is accommodated in the adsorbent use container 21 . The carbon dioxide adsorbent 31 has air permeability. Further, the carbon dioxide adsorbent 31 includes a plurality of granular carbon dioxide adsorbents. The external shape of each carbon dioxide adsorbent is, for example, pellet-like or bead-like.

Note that the configuration of the carbon dioxide adsorbent 31 is not limited to a configuration including a plurality of granular carbon dioxide adsorbents. For example, the carbon dioxide adsorbent 31 may be formed of a honeycomb-shaped carbon dioxide adsorbent.

As the car 8 moves, air in the hoistway 1 is passed through the carbon dioxide adsorbent 31 . That is, as the cage 8 moves downward, air enters the adsorbent use container 21 from the lower surface of the use container main body 21a. The air that has entered the adsorbent use container 21 passes through the carbon dioxide adsorbent 31 and is discharged to the outside of the adsorbent use container 21 from the upper surface of the use container main body 21a.

Carbon dioxide in the air is adsorbed by the carbon dioxide adsorbent 31 when passing through the adsorbent use container 21 .

Although not shown in FIG. 1, an adsorbent recovery container 22 and an adsorbent replenishment container 23 are installed on the wall 1a of the hoistway 1 facing the back side of the car chamber 11. The adsorbent recovery container 22 and the adsorbent replenishment container 23 are arranged at intervals from each other in the vertical direction.

Further, the adsorbent use container 21, the adsorbent recovery container 22, and the adsorbent replenishment container 23 are arranged at the same position in the width direction of the cage 8.

The adsorbent replenishment container 23 has a cylindrical replenishment container main body 23a and a flat replenishment container lid 23b. A replenishment container upper opening is provided at the upper end of the replenishment container main body 23a. A replenishment container lower opening is provided at the lower end of the replenishment container main body 23a.

The replenishment container lid 23b is provided at the lower part of the replenishment container main body 23a. Further, the replenishment container lid 23b opens and closes the lower opening of the replenishment container.

A use container opening is provided at one end of the adsorbent use container 21 facing the wall 1a where the adsorbent recovery container 22 and the adsorbent replenishment container 23 are provided. The used container lid 21b opens and closes the used container opening.

At least one of the adsorbent use container 21, the car 8, and the hoistway 1 is provided with an exchange mechanism 24. The exchange mechanism 24 of the first embodiment includes a container rotation device 25 and a lid rotation device 26. Motors are used as the container rotation device 25 and the lid rotation device 26, respectively.

The container rotation device 25 is provided on one of the pair of support arms 16 . That is, the container rotation device 25 is provided on the car 8 via the support arm 16. Further, the container rotating device 25 rotates the adsorbent use container 21 with respect to the car 8 between a horizontal state and an inclined state around an axis parallel to the width direction of the car 8.

The horizontal state is a state in which the adsorbent use container 21 is horizontal, as shown in FIG. The tilted state is a state in which the adsorbent use container 21 is tilted with respect to the horizontal plane, as shown in FIGS. 3 and 4.

The lid rotating device 26 opens and closes the opening of the container by rotating the lid 21b of the container with respect to the container main body 21a.

The exchange mechanism 24 connects the adsorbent use container 21 to the adsorbent recovery container 22 when the car 8 stops at a position corresponding to the adsorbent collection container 22 , and removes the carbon dioxide adsorbent 31 in the adsorbent use container 21 . is moved into the adsorbent collection container 22.

Furthermore, when the car 8 stops at a position corresponding to the adsorbent replenishment container 23 , the exchange mechanism 24 connects the adsorbent use container 21 to the adsorbent replenishment container 23 and adsorbs carbon dioxide in the adsorbent replenishment container 23 . The body 31 is moved into the adsorbent use container 21.

The carbon dioxide recovery device 30 of the first embodiment includes an adsorbent use container 21, an adsorbent recovery container 22, an adsorbent replenishment container 23, and a replacement mechanism 24. Further, the carbon dioxide recovery device 30 is controlled by the elevator control device 5. That is, the container rotation device 25 and the lid rotation device 26 are controlled by the elevator control device 5.

FIG. 3 is a side view showing a state in which the carbon dioxide adsorbent 31 has been moved from the adsorbent use container 21 to the adsorbent recovery container 22 in FIG. In addition, in FIG. 3, a cross section of the adsorbent use container 21 and the adsorbent collection container 22 is shown.

When recovering the carbon dioxide adsorbent 31 that has been adsorbed with carbon dioxide into the adsorbent recovery container 22, the car 8 is stopped at a position corresponding to the adsorbent recovery container 22. In this example, the position corresponding to the adsorbent collection container 22 is a position where the adsorbent use container 21 is located above the adsorbent collection container 22, and the adsorbent use container 21 is connected to the adsorbent collection container 22. This is a possible position.

After this, the adsorbent use container 21 is tilted so that the opening of the use container faces downward. Then, the used container lid 21b is rotated so that the tip of the used container lid 21b touches the edge of the upper opening of the collection container.

As a result, the carbon dioxide adsorbent 31 in the adsorbent use container 21 moves into the adsorbent recovery container 22 due to its own weight. That is, by tilting the adsorbent use container 21 with respect to the horizontal plane, the exchange mechanism 24 moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent collection container 22 by the weight of the carbon dioxide adsorbent 31. move it to

FIG. 4 is a side view showing a state in which the carbon dioxide adsorbent 31 has been moved from the adsorbent replenishment container 23 to the adsorbent use container 21 in FIG. In addition, in FIG. 4, cross sections of the adsorbent use container 21 and the adsorbent replenishment container 23 are shown.

When replenishing the empty adsorbent use container 21 with the carbon dioxide adsorbent 31 before carbon dioxide adsorption, the car 8 is stopped at a position corresponding to the adsorbent replenishment container 23. In this example, the position corresponding to the adsorbent replenishment container 23 is a position where the adsorbent use container 21 is located below the adsorbent replenishment container 23, and the adsorbent use container 21 is connected to the adsorbent replenishment container 23. This is a possible position.

Thereafter, the adsorbent use container 21 is tilted so that the opening of the use container faces upward. Then, the use container lid 21b is rotated to open the use container opening. At this time, the used container lid 21b hits the replenishment container lid 23b, and the rotation of the used container lid 21b also rotates the replenishment container lid 23b in the opening direction.

As a result, the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 moves into the adsorbent usage container 21 due to its own weight. That is, the exchanging mechanism 24 tilts the adsorbent use container 21 with respect to the horizontal plane and opens the replenishment container lid 23b, so that the carbon dioxide in the adsorbent replenishment container 23 is removed by the weight of the carbon dioxide adsorbent 31. The carbon adsorbent 31 is moved into the adsorbent use container 21.

When the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished into the adsorbent use container 21, the use container opening is closed by the use container lid 21b, and the adsorbent use container 21 is returned to a horizontal state.

FIG. 5 is a block diagram showing an elevator carbon dioxide recovery system according to the first embodiment. The carbon dioxide recovery system includes an elevator control device 5, a carbon dioxide recovery device 30, and a monitoring device 40.

The monitoring device 40 includes a replacement determination section 41, a replacement command section 42, and a notification section 43 as functional blocks.

The replacement determination unit 41 determines whether or not the carbon dioxide adsorbent 31 needs to be replaced. For example, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced based on a preset replacement cycle.

Note that the replacement determination unit 41 may determine whether replacement is necessary based on the operation information of the car 8. In this case, the replacement determination unit 41 acquires the operation information of the car 8 from the elevator control device 5. The operation information of the car 8 includes, for example, travel time information or travel distance information. The travel time information is information on the total travel time of the car 8. The moving distance information is information on the total moving distance of the car 8.

A travel time threshold or a travel distance threshold is set in the monitoring device 40. Then, the replacement determination unit 41 determines that it is necessary to replace the carbon dioxide adsorbent 31 when the total travel time of the car 8 reaches the travel time threshold or when the total travel distance of the car 8 reaches the travel distance threshold. It is determined that

Moreover, the weight of the carbon dioxide adsorbent 31 increases as it adsorbs carbon dioxide and moisture in the air. Further, as carbon dioxide and moisture are adsorbed, the carbon dioxide adsorption capacity of the carbon dioxide adsorbent 31 gradually decreases. Therefore, the replacement determination unit 41 may determine whether replacement is necessary based on the weight of the carbon dioxide adsorbent 31 in the adsorbent use container 21.

In this case, the adsorbent use container 21 is provided with a weight detector (not shown). The weight detector detects the weight of the carbon dioxide adsorbent 31. The monitoring device 40 acquires information from the weight detector directly or via the elevator control device 5.

A weight threshold value is set in the monitoring device 40. Then, when the weight of the carbon dioxide adsorbent 31 reaches the weight threshold, the replacement determining unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

Further, the replacement determination unit 41 may determine whether or not the carbon dioxide adsorbent 31 needs to be replaced based on the elapsed time since the previous replacement of the carbon dioxide adsorbent 31 .

In this case, an elapsed time threshold is set in the monitoring device 40. Then, when the elapsed time since the previous replacement reaches the elapsed time threshold, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

Furthermore, the replacement determination unit 41 may determine whether or not the carbon dioxide adsorbent 31 needs to be replaced based on the carbon dioxide concentration in the air that has passed through the adsorbent use container 21 .

In this case, the adsorbent use container 21 is provided with a concentration sensor (not shown). The concentration sensor detects the concentration of carbon dioxide.

A concentration threshold value is set in the monitoring device 40. Then, the replacement determining unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced when the carbon dioxide concentration in the air that has passed through the adsorbent use container 21 becomes equal to or higher than the concentration threshold value.

The replacement command unit 42 transmits a replacement command signal to the elevator control device 5 when the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

Upon receiving the replacement command signal from the monitoring device 40, the elevator control device 5 moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22 at a timing when no call registration has occurred. Then, the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 is moved into the adsorbent use container 21.

The notification unit 43 transmits a notification signal to the information center 60 via the communication network 50 when a replacement command signal is transmitted from the replacement command unit 42 to the elevator control device 5 . The notification signal is a signal that notifies that the carbon dioxide adsorbent 31 has been replaced.

Upon receiving the notification signal, the information center 60 notifies the person in charge of maintenance of the elevator where the carbon dioxide adsorbent 31 has been replaced that the carbon dioxide adsorbent 31 has been replaced.

Thereafter, a maintenance person who has been contacted by the information center 60 collects the carbon dioxide adsorbent 31 from the adsorbent collection container 22 and replenishes the adsorbent replenishment container 23 with carbon dioxide adsorbent 31. be exposed. These operations can be performed by a maintenance person riding on the car 8, for example.

The carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide is heated by a heating device (not shown). As a result, carbon dioxide is separated from the carbon dioxide adsorbent 31, and the carbon dioxide adsorbent 31 is returned to the state before carbon dioxide adsorption.

FIG. 6 is a flowchart showing replacement determination processing by the monitoring device 40 of FIG. The monitoring device 40 repeatedly executes the replacement determination process shown in FIG. 6 at a set period.

When the replacement determination process is started, the monitoring device 40 determines whether or not the carbon dioxide adsorbent 31 needs to be replaced in step S101. If the carbon dioxide adsorbent 31 does not need to be replaced, the monitoring device 40 ends the process for that time.

If it is necessary to replace the carbon dioxide adsorbent 31, the monitoring device 40 transmits a replacement command signal to the elevator control device 5 in step S102. After this, the monitoring device 40 transmits a notification signal to the information center 60 in step S103, and ends the processing for that time.

In such an elevator and its carbon dioxide recovery device 30, the adsorbent use container 21 is provided in the car 8. A carbon dioxide adsorbent 31 is accommodated in the adsorbent use container 21 . By moving the car 8 with the carbon dioxide adsorbent 31 housed in the adsorbent use container 21, the air in the hoistway 1 is passed through the carbon dioxide adsorbent 31, and the carbon dioxide in the air is absorbed by carbon dioxide. It is adsorbed to the body 31.

Therefore, regardless of the length of the hoistway 1 in the vertical direction, carbon dioxide in the hoistway 1 can be efficiently recovered using the driving force of the hoist 3.

Further, an adsorbent recovery container 22 is installed in the hoistway 1. Then, the exchange mechanism 24 connects the adsorbent use container 21 to the adsorbent recovery container 22 and moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22.

Therefore, regardless of the position of the adsorbent use container 21 in the cage 8, the carbon dioxide adsorbent 31 containing only the carbon dioxide adsorbent can be easily recovered, and the effort of maintenance work can be reduced.

In addition, by tilting the adsorbent use container 21 with respect to the horizontal plane, the exchange mechanism 24 moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22 using its own weight. move it to Therefore, with a simple configuration, it is possible to easily recover the carbon dioxide adsorbent 31 containing only the carbon dioxide adsorbent.

Further, an adsorbent replenishment container 23 is installed in the hoistway 1. Then, the exchange mechanism 24 connects the adsorbent use container 21 to the adsorbent replenishment container 23 and moves the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent use container 21.

Therefore, irrespective of the position of the adsorbent use container 21 in the cage 8, it is possible to easily replenish the carbon dioxide adsorbent 31 before adsorbing carbon dioxide, and the effort required for maintenance work can be reduced. Thereby, the degree of freedom in the installation position of the adsorbent use container 21 in the car 8 can be improved.

Furthermore, carbon dioxide recovery efficiency can be maintained for a longer period of time, and maintenance work intervals can be lengthened.

In addition, the exchanging mechanism 24 tilts the adsorbent use container 21 with respect to the horizontal plane and opens the replenishment container lid 23b, so that the carbon dioxide in the adsorbent replenishment container 23 is removed by the weight of the carbon dioxide adsorbent 31. The carbon adsorbent 31 is moved into the adsorbent use container 21. Therefore, with a simple configuration, it is possible to easily replenish the carbon dioxide adsorbent 31 before carbon dioxide adsorption.

Furthermore, in the monitoring device 40 of the carbon dioxide recovery system according to the first embodiment, the replacement determination unit 41 determines whether or not the carbon dioxide adsorbent 31 needs to be replaced. Then, when the replacement determining unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced, a replacement command signal is transmitted to the elevator control device 5.

Therefore, by replacing the carbon dioxide adsorbent 31 at a more appropriate timing, the adsorption performance of the carbon dioxide adsorbent 31 is maintained, and carbon dioxide can be efficiently recovered over a longer period of time.

Further, when a replacement command signal is transmitted from the replacement command unit 42 to the elevator control device 5, a notification signal is transmitted from the notification unit 43 to the information center 60. Therefore, the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide can be recovered or the carbon dioxide adsorbent 31 that has not yet adsorbed carbon dioxide can be replenished at a more appropriate timing. As a result, carbon dioxide can be efficiently recovered over a longer period of time, and maintenance work can be reduced.

Note that the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be installed on a wall facing the side surface of the car chamber 11 in the hoistway 1, avoiding the car guide rail.

Embodiment 2.
Next, FIG. 7 is a side view showing the main parts of the elevator according to the second embodiment. Although omitted in FIG. 1, a landing threshold 17 is provided at each of the landings on multiple floors. Each landing sill 17 guides the lower end of the landing door 13 during the opening/closing operation of the landing door 13. A fascia plate 18 is provided at the bottom of each landing sill 17.

The adsorbent recovery container 22 and the adsorbent replenishment container 23 are provided on different fascia plates 18 from each other. Further, each of the adsorbent recovery container 22 and the adsorbent replenishment container 23 also serves as part or the entirety of the fascia plate 18. Further, each of the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be a container attached to the flat fascia plate 18.

Each of the adsorbent recovery container 22 and the adsorbent replenishment container 23 is located within the range between the wall 1b of the hoistway 1 on the landing side and the end surface of the hoistway 1 side of the hoistway sill 17 in the front-rear direction of the car 8. positioned. The front-rear direction of the car 8 is perpendicular to the width direction of the car 8 and is horizontal.

A recovery container door 27 is provided on the landing wall of the floor where the adsorbent recovery container 22 is installed. The collection container door 27 opens and closes a collection container opening (not shown). The carbon dioxide adsorbent 31 in the adsorbent collection container 22 can be taken out from the landing through the collection container opening.

In this case, the carbon dioxide adsorbent 31 is taken out from the adsorbent recovery container 22 while the adsorbent recovery container 22 remains installed in the hoistway 1 . Further, the carbon dioxide adsorbent 31 may be taken out from the adsorbent collection container 22 while the adsorbent collection container 22 is taken out to the landing area.

A replenishment container door 28 is provided on the hall wall of the floor where the adsorbent replenishment container 23 is installed. The refill container door 28 opens and closes a refill container opening (not shown). The carbon dioxide adsorbent 31 can be replenished into the adsorbent replenishment container 23 from the landing area through the replenishment container opening.

In this case, the carbon dioxide adsorbent 31 is replenished into the adsorbent replenishment container 23 while the adsorbent replenishment container 23 remains installed in the hoistway 1 . Further, the adsorbent replenishing container 23 may be replenished with the carbon dioxide adsorbent 31 while the adsorbent replenishing container 23 is taken out to the landing.

In this manner, in the second embodiment, the carbon dioxide adsorbent 31 can be taken out from the adsorbent collection container 22 from the landing. Furthermore, the carbon dioxide adsorbent 31 can be refilled into the adsorbent replenishment container 23 from the landing area.

Other configurations in the second embodiment are similar to those in the first embodiment.

With such a configuration as well, the same effects as in the first embodiment can be obtained. Moreover, the effort required for maintenance work can be further reduced.

Furthermore, the removal of the carbon dioxide adsorbent 31 from the adsorbent recovery container 22 and the replenishment of the carbon dioxide adsorbent 31 into the adsorbent replenishment container 23 can be carried out without stopping the operation of the car 8. Therefore, compared to the case where the carbon dioxide adsorbent 31 is replaced on the car 8, the degree of freedom in the timing of the replacement work is improved. As a result, it is possible to shorten the time during which the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide remains in the adsorbent recovery container 22 and the time during which the adsorbent replenishment container 23 is empty. The recovery efficiency of carbon dioxide in the hoistway 1 can be further improved.

Further, the adsorbent recovery container 22 and the adsorbent replenishment container 23 are provided on the fascia plate 18, respectively. Therefore, the adsorbent recovery container 22 and the adsorbent replenishment container 23 can be installed in the hoistway 1 by effectively utilizing the space within the hoistway 1.

Note that the method for recovering the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide is to replace the adsorbent recovery container 22 filled with the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide with an empty adsorbent recovery container 22. It may be.

Further, a method for replenishing the carbon dioxide adsorbent 31 before carbon dioxide adsorption is a method of replacing an empty adsorbent replenishing container 23 with an adsorbent replenishing container 23 filled with the carbon dioxide adsorbent 31 before carbon dioxide adsorption. It may be.

Further, the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be a common container. That is, a collection/replenishment container that serves both as the adsorbent collection container 22 and the adsorbent replenishment container 23 may be used. In this case, the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide is taken out from the collection/replenishment container, and the carbon dioxide adsorbent 31 that has not yet adsorbed carbon dioxide is replenished into the collection/replenishment container. In addition, the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished from the collection/replenishment container to the adsorbent usage container 21, and the carbon dioxide adsorbent 31 that has already absorbed carbon dioxide is collected from the adsorption material usage container 21 to the collection/replenishment container. be done.
