Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the structure of an elevator system for transporting luggage and people.

[Conventional technology]

Elevator devices for transporting people and cargo are hydraulic jack type for lower floors and for small groups of people, and as shown in Japanese Patent Application Laid-Open No. 611'97386 and No. 62-41178, there are two types of elevator equipment for transporting people and cargo: There are several types of elevator cars that use equipment to move the elevator car up and down, but the most common type is a lobe type that uses a main rope.

Figure 7 shows a conventional elevator system, in which (
1) is the M-R path of the elevator installed in the building.In this hoistway (1), a single car frame (2) is arranged, and in this car frame (2), the elevator There is also a counterbalance 8iI located on the side of the cage (3) in the E-falling path (1). (Counterway 1-)
(4) is placed.

(5) is a machine room installed at the top of the hoistway (1), and a hoisting machine (not shown) equipped with a rotatable sheave (6) is installed inside this machine room (5). At the same time, a warping wheel (7) located below the sheave (6) is rotatably provided. (8) is the main rope wrapped around this warping wheel (7) and sheave (6), and both ends of this main rope (8) hanging down inside the hoistway (1) are as shown in Fig. 7. It is connected to the car frame (2) and the counterweight (4), respectively.

(9) is a car shock absorber installed at the bottom of the hoistway (1), and the car shock absorber (9) is located directly below this door (3).
has the function of alleviating and preventing the collision between the bit floor and the cage (3). (10) is a counterweight buffer installed at the bottom of the hoistway (1), and the counterweight buffer (10) located directly below the counterweight (4) is connected to the bit floor and counterweight. (4) Performs the function of mitigating and preventing collisions.

Due to the rotation of the sheave (7) based on the drive of the hoist, the car (3) moves downward in the Y direction while being guided by a guide rail (not shown), and as the car (3) moves up and down, It is guided by a counterweight (4) or a guy rail (not shown) and is lowered or moved upward to compensate for the weight on the side of the cage (3).

[Problem to be solved by the invention]

The conventional elevator system is constructed as described above, and because only a single heel (3) is disposed in the hoistway (1), there is a problem in that the transportation capacity cannot be improved.

In view of this, Japanese Patent Application Laid-open No. 61-90976 proposes an elevator system in which two cars connected in a common cage frame are operated. , and the convenience of users moving in a concentrated manner on a specific floor, but on the other hand, the two elevators installed in series always move up and down together, making it impossible to accommodate individual movements. . Furthermore, there are drawbacks such as the floor used by a user of one car being unavailable to users of other cars, making it impossible to achieve efficient operation.

In order to eliminate this drawback, Japanese Patent Application Laid-Open No. 58-197183 discloses that two cars placed in one hoistway are moved up and down individually by two drive devices placed in a machine room at the top of the hoistway. We are proposing a method for efficiently operating elevator equipment. However, in this elevator system, the driving device becomes large and a very large space must be secured in the machine room, and in order to avoid this, the hoisting device must be specially miniaturized. Ta. In addition, a penetrating vibrator was installed in the center of the car located above, and the main rope for raising and lowering the car below was inserted through this penetrating pipe, which caused problems for passengers to get on and off the elevator. There was no limit to improving the transport capacity of the vehicle as desired. Furthermore, in this elevator system, the upper car is suspended by the main rope, so if a failure occurs in the drive unit k, the upper car that falls will come into contact with or collide with the lower car, and the lower corner will be damaged. There was a problem in that they could get involved in an accident and the damage would expand.

The present invention has been made in view of the above points, and an object of the present invention is to provide an elevator system that can significantly improve transportation capacity by suppressing and eliminating the various disadvantages mentioned above.

38) respectively. In this example, a single screw rod (12) is used, but a plurality of screw rods (12) are used.
12). Further, although this embodiment shows the use of two heels (3) and (3A), the present invention is not limited to this.

(13) is a plurality of guide rollers attached to the upper and lower parts of the vertical frames constituting the plurality of car frames (2) and (28),
This guide roller (I3) engages with the opposing guide rail (11) as shown in FIG.
2A) lifting and lowering (hyperactivity, paraphrasing), multiple heels (3).
(3A) functions to smooth the vertical movement.

(14) is an electric motor attached to the lower side of the vertical frame constituting the plurality of car frames (2) and (28), respectively, using a handle member. , are each equipped with a pulse generator (not shown), and pulleys (15) are fitted onto the upwardly directed output shafts of the plurality of electric motors (14), respectively, as shown in FIG. In this embodiment, an electric motor (14) is used as the drive device, but the present invention is not limited to this.

(16) is a ball nut that is a rotating body that is supported by a mounting member in the center of the horizontal construction member that constitutes a plurality of car frames (2) and (28), and these ball nuts (16) As shown in Figure 2, ``Second Screw Rod (12)''
A heald (17) for power transmission is wound around each of the plurality of bolts (2δ) and the pulley (15). In this embodiment, a single ball nut (16) is attached to the car frame (2).
) and (2A), but a plurality of ball nuts (16) may be supported on the car frames (2) and (2A), respectively. However, the electric motor (
When the pulley (15) rotates as the pulley (14) is driven, the belt (17) circulates and rotates the ball neck h (1B) in the horizontal direction, and the cages (3) and (3A) move along the pair of guide rails (11). ) and move up and down individually.

The range of this vertical movement is from the top floor to the bottom floor +α for the car (3), and from the bottom floor to the top floor -α floor for the car (3A). This α is the distance for collision prevention between the car (3 cars (3A)).
・It is determined based on the physical dimensions of (3A), but is usually about the length of one or two floors.

(18) is a power source that supplies power for driving and lighting to the above cages (3) and (3A) and multiple electric motors (14), and this power source (J8) and cages (3) and (38) are , as shown in Fig. 1, control cables (19) and (19Δ) are connected, respectively. Reference numeral (20) denotes a calling device, and this calling device (20) has the function of generating car call and hall call signals as shown in FIG.

(21) is the cable and calling device (
As shown in FIG. 1, this control device (21) is a control device (microcomputer) electrically connected to a microprocessor ((:PL)) (21a),
random access memory (RAM) (21b);
It is equipped with a read-only memory (ROM) (21C) and an interface (T/F) (21d), and is capable of manually generating pulses from a pulse generator (not shown) of the plurality of electric motors (14) (3).・While calculating the position of (3A), input the car call and hall call signals of caller fff(2[1), and send drive commands to electric motors (14) and (14) based on these human signals. It performs the action of outputting. The control device (2nd construction) that controls the vertical movement of the cars (3) and (3A) is designed to prevent collisions caused by the movement of the cars (3) and (3A) in adjacent directions. 3)
・Determine the non-collision range of (38) and then calculate (3)・(3A
) also has the function of regulating movement in adjacent directions.

That is, the control device (21) allows free upward movement of the heel (3) in the case of downward movement of the car (38), while allowing free upward movement of the heel (3) in the case of downward movement of the car (3A).
), as shown in Figure 3, when the car (3
Based on the call signal and running direction signal of car (3) and (3A), it is determined whether car A) is moving to the lowest floor position where it will land + 6th floor (non-collision range), and whether car (3) or car will collide. If it is determined that the car exists within the range, an appropriate drive command is sent to the car (3
) to the electric motor (14) to regulate the downward movement of the cage (3).

In addition, when the car (3A) is moved upward,
), as shown in Figure 3, when the bracket (3
Based on the call signals and running direction signals of cars (3) and (3A), it is determined whether or not the car is moving to the highest floor position + α (non-collision range) where car (3) will land. If it is determined that the vehicle is within the collision range, apply an appropriate drive command (3
) to the electric motor (14) to regulate the downward movement of the heel (3).

Then, in the case of upward movement of the car (3), the car (3)
As shown in Figure 3, when Δ) moves upward, the corner (
3) Based on the call signal and running direction signal of car (3) and (3Δ), it is determined whether the car is moving to the highest floor position minus α (non-collision range), and the car (38) is moved. If it is determined that the vehicle is within the collision range, an appropriate drive command is sent (
3A) to control the upward movement of the cage (3A).

Due to the regulation of this control device (21), there are rare cases where passengers boarding the car (3) are unable to go to their desired floor, but the direction of movement of the car (3Δ) may change over time. Since the handle (3) is allowed to move up and down freely, there is no problem with separate installation. Furthermore, in order to prevent passengers from being confused in such a case, measures may be taken such as installing a display inside the car (3) to display the situation.

As described above, according to the present invention, since the cars (3) and (3A) are moved up and down individually, it is expected that service efficiency and transportation capacity will be significantly improved.

In addition, the electric motor (14) that rotates the 5 6 ball nut (16) that rotates to move the cages (3) and (38) up and down and the pole neck (+116) is installed on the legs (3) and (3A), respectively. Therefore, the counterweight (4) and machine room (5)
), hoisting machine, sheave (6), warping wheel (7), car shock absorber (9), and counterweight shock absorber (10) are omitted, space is saved, and maintenance and inspection work is made easier. It becomes possible.

Then, a ball nut with a high friction coefficient (
Since the baskets 16) and (16) are mechanically screwed together, it is possible to reliably prevent the baskets (3) and (3A) from falling.

Furthermore, the control device (21) determines the non-collision range of the cars (3) and (3A) and restricts the vertical movement of the cars (3) and (3A) in the adjacent direction. 3A) can be expected to reliably prevent collisions.

In the above embodiment, the non-collision range of the car (3)/(3A) is determined based on the call signal and running direction signal of the car (3)/(3A), and the adjacent car (3)/(3A) is determined. Although the car position detection device uses a control device (21) to restrict the movement in the direction, the car position detection device
It is also possible to detect the position of the caller and suppress movement in an adjacent direction when the caller is in an adjacent position, or to give priority to calls in an anti-adjacent direction. Also, adjacent to (3)・(3A
), the priority can be set to one car, and in the case of overlapping service zones, the car with priority is moved first. play. In the above embodiment, the basket (3)
・Although the hoistway (1) that simply accommodates (38) is shown, storage spaces for waiting cages (3) and (38) are provided at the top and bottom of the hoistway (1), respectively. 3).It goes without saying that even if the range of vertical movement in (3A) is expanded from the top floor of the hoistway (1) to the top floor, the same effects as in the above embodiment can be achieved.

In addition, although the above-mentioned embodiment simply uses a screw rod (12), the thread pitch of the screw rod (12) is shortened and the angle for the screw is made smaller, thereby improving the safety of the elevator system. You may also let them do so. That is, Kako (
3) becomes impossible to move up and down, and if an abnormality occurs in the braking device (not shown) and the car (3) falls at an abnormal speed, the car (3A) will be involved in an accident, which could be a serious problem that could affect the lives of the passengers. There is a risk of an accident or mishap. Therefore, by shortening the screw pitch of the screw rod (12) and reducing the angle of the screw thread, the resistance to free fall between the screw surface of the screw rod (12) and the ball nut (16) can be greatly improved. Therefore, the free fall of the car (3) can be suppressed and eliminated, and the safety of the elevator system can be greatly increased. In this case, only the thread pitch and thread thread in the main part of the threaded rod (12) may be changed.

Next, FIGS. 4 and 5 show a second embodiment of the present invention. In the figures, (22) denotes a plurality of brackets 1 to 1 fixed to the wall of the hoistway (1). Multiple brackets (22
), as shown in FIG. 4, a columnar rack (23) extending over the entire length of the hoistway (1) is vertically attached.

(14) The electric motors are respectively disposed on the car frames (2) and (28), and each of the plurality of electric motors (14) is equipped with a brake (24) for braking the electric motors (14). In addition, small-diameter gears (25) are fitted to the horizontally oriented output shafts of the plurality of electric motors (14), respectively. (26) A pair of support parts provided on the bracket frames (2) and (28) respectively.In the past, the plurality of pairs of support members (26) each rotatably supported the shaft (27). , At the tip of this shaft (27), there is a gear (25) marked -F.
A large-diameter reduction gear (28) that meshes with the shaft (28) is fitted, and a shaft (28) located between the pair of support members (26) and (26) is fitted.
A binion (29), which is a rotating body that meshes with the rack (23), is fitted into the substantially central portion of the rack (7) (see FIGS. 4 and 5). The other parts are the same as those described above.

However, when the gear (25) rotates as the electric motor (14) is driven, the reduction gear (28) rotates and rotates the shaft (27), causing the binion (29) meshed with the rack (23) to move vertically. As it rotates, cages (3) and (3A) move up and down individually.

In this embodiment, the same effect as in the above embodiment can be expected, and the belt (17) which impairs slip loss is omitted, and the gear (25) and the reduction gear (28) are directly meshed with each other. Therefore, large power transmission is possible.

Next, an example in which the elevator system according to the present invention and a normal lobe type elevator system are installed together in a building is shown in Figure 6 (
The explanation will be based on a).

In FIG. 6(a), the elevator system of the first embodiment is installed in a building occupied by companies A, B, and 0, each occupying a service zone consisting of multiple floors. In view of the fact that there is no need to move elevator cars up and down between multiple companies, there are cars (3) and (3A) in the male-exit path (1) of this elevator device that move up and down only in each service zone. - (3B) is placed. Further, within the hoistway (1), screw rods (12) (not shown in FIG. 6(a)) having lengths corresponding to each service zone are vertically arranged.

On the other hand, within the hill, a normal lobe-type elevator device is installed adjacent to the elevator device, and in the hoistway (30) up to the 7th floor of this elevator device, Company A, Company B, 0 Each floor of the company (1st floor, 4th floor, 7th floor in the figure)
A single elevator car that runs at high speed and stops only at the service zone (floor) is arranged so that passengers can go up and down only in each service zone. Moving (3)・(3A)
・You can now transfer and use (3B).

However, in this embodiment, since each service zone is set independently without overlapping, in addition to the effects mentioned above, the basket (
3), (3A), and (3B), and the control of the control device (21) (not shown in FIG. 6(a)) can be significantly simplified. Also, y-tough road (3
The transportation capacity can be greatly improved by keeping the car (3) to the minimum size up to the 7th floor.
・Since (3Δ) and (3B) are moved up and down only in each service zone, a significant reduction in passenger waiting time can be expected.

In the above embodiment, a plurality of screw rods (1
2) is shown, or if a support column is fixed to the wall of the hoistway (1) between each service zone, and a vertically long screw rod (12) is supported vertically on this support column. , the rigidity of the screw rod (12) can be significantly improved,
The applicability to high-rise buildings etc. can be significantly increased. Furthermore, the range of movement of the elevator car in the JP- elevator car may be expanded so that it stops at each floor from the 1st floor to the 100th floor. Furthermore, although the above-mentioned embodiment shows an elevator system in which the elevator system according to the first embodiment described above is disposed within the hill, it is also possible to arrange the elevator system according to the above-mentioned second embodiment in the hill. It has the same effect as the example.

Next, an example in which the elevator system according to the present invention and a normal lobe type elevator system are used together in a hospital is shown in FIG.
The explanation will be based on b).

Figure 6 (l) shows the structure of the hospital.In this hospital, there are rooms for outpatient examinations and office work on the first to third floors, and an operating room on the fourth floor. Hospital rooms for inpatients are located from the 5th floor to the 100th floor. The elevator system of the first embodiment is installed in this hospital, and in the hoistway (1) of this elevator system, there is an elevator system for inpatients who move up and down from the 4th floor to the 100th floor. Kato (
3) and emergency hospitalization cages (3Δ) that move up and down the range from 1@ floor to the 4th floor are placed respectively, and the up and down movement speed of these cages (3) and (3A) is Consideration has been given to the degree of impact on the patient and safety. Furthermore, the car (3A) is always on standby on the first floor, and in an emergency, it is given priority and moves up to the fourth floor.

On the other hand, in the hospital, a normal lobe-type elevator system is installed adjacent to the elevator system, and the hoistway (30) of this elevator system is used to move up and down from the 1st floor to the 100th floor. There is a single elevator car for the general public.

However, in this embodiment, special service operations are shared between Kato (3) and (3A), and service operations for securing time or transportation volume are assigned to a single elevator. It happens.

It is clear that the same effects as in FIG. 6(a) can be expected in this example as well, and that the safety for patients can be greatly improved.

In the second embodiment, the elevator system according to the first embodiment 3 4 is installed in a hospital, but the elevator system according to the second embodiment described above is installed in the hospital. Also, the same effect as in the above embodiment is achieved.

Further, the elevator apparatus shown in FIGS. 6(a) and 6(b) can be easily applied to other systems other than those described above. For example, 31iP from the first floor! In the case of a building where many shops are located up to the floor and a hotel is located on the 4th floor or above, the basket (3) is in charge of moving to the living room floor on the 4th floor or above, and the 1st floor You may also have Kato (3B) in charge of moving from there to the hotel lobby on the 4th floor. This kind of misalignment makes it difficult to secure security services and transportation to guest rooms.
This can be made possible with a hoistway.

As described above, according to the present invention, it is possible to provide an elevator system with extremely high utility value, and moreover, the usage method and floor switching can be extremely controlled by changing the settings of the control device (21). It is possible to change it easily.

〔Effect of the invention〕

As described above, according to the present invention, transportation capacity is significantly improved, efficiency of operation of individual elevator cars is increased, machine room is omitted, collisions between adjacent elevator cars are prevented, elevator cars are prevented from falling, and elevator landings are improved. It is possible to provide an elevator device that can significantly shorten the waiting time for getting down.
