Abstract

PROBLEM TO BE SOLVED: To allow both upper and lower cars to properly and smoothly reach floors and open the door even if the space between the upper and lower cars and the space between the floors of the building are different from each other in a double deck elevator. SOLUTION: The upper car 21 and lower car 22 are provided with an upper car arrival detecting switch 24a and a lower car arrival detecting switch 24b respectively. The controller section 82 in a main controller 8 allocates the upper car 21 or the lower car 22 for the calling registration by a landing call button 9 and also controls the arrival of the allocated car to arrive at a specified floor based on the signal from the car arrival detecting switch 24a or 24b corresponding to the allocated car. Therefore, since the controller 82 arrives at the intended floor based on the signal from their respective car arrival detecting switches corresponding to the individual cars, such case that either upper or lower car can not arrive at an arrival zone due to the difference in spaces between floors as in a conventional system can be avoided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope-type double-deck elevator control device provided with a car for carrying passengers connected vertically in two stages.

[0002]

2. Description of the Related Art In an elevator installed in a building such as a building, in addition to a single-deck elevator having a single car, two cars are connected up and down.
There is a double-deck elevator consisting of cars as floors.

A two-story double-deck elevator can carry many passengers at one time within a limited elevator installation volume in a building, and is therefore required in high-rise buildings and the like that require increased transport capacity. is increasing.

[0004] The operation system of the double deck elevator includes:
The lower car is always on the odd floor only, and the upper car is always on the even floor only.
The so-called double operation in which landing is stopped at every floor and the service is performed, the single operation in which only one of the cars (for example, the lower car) is stopped on an arbitrary designated floor, and the single operation and the double operation are used in combination. In addition, there are three types of semi-double operation in which services are provided without restrictions on odd and even floors.

[0005] Rope type double deck elevators,
Like the single-deck elevator, the car is provided with one landing detection switch, and the main controller uses the landing detection switch to determine the landing position provided for each floor in the hoistway. Receiving a position detection signal between the detector and
Control is performed so that the car can be placed on the designated floor and opened.

A schematic structure of a conventional rope type double deck elevator will be described with reference to FIG. FIG. 4 shows the hoistway 1
FIG. 2 is a longitudinal sectional view of the inside of the car 2 as viewed from the side, and as shown, a hoist 3 is installed in a machine room on the hoistway 1, and a drive sheave of the hoist 3 Wound main rope 4
Connects the car 2 and the counterweight 5 to both ends, and the connected car 2 and the counterweight 5 are guided by guide rails (not shown) by the rotational driving force of the hoisting machine 3, respectively, while the hoistway 1 Move up and down inside. A balancing rope 7 is connected between the car 2 and the counterweight 5 via a tensioner 6 installed in a pit of the hoistway 1.

[0007] A pulse generator (not shown) is connected to the hoisting machine 3, and the pulse generator sends a pulse signal corresponding to the rotation speed of the hoisting machine 3 to a main control device also installed in the machine room on the rooftop. 8.

Therefore, the main controller 8 obtains information on the position and speed of the car 2 in the hoistway 1 based on the signal from the pulse generator, and on the other hand, calls the car by the hall call button 9 provided at each hall. It is configured to receive a registration signal and a destination floor registration signal from the car operation panels 21a and 22a in the upper and lower cars 21 and 22, and to control the car 2 to land on the designated floor and open the door. .

That is, as shown in the block diagram of the control device in FIG. 5, a call registration signal (a hall call signal) from each hall call button 9 is transmitted to a hall controller unit 10 installed corresponding to each hall, and The destination floor registration signal (car call signal) supplied to the input / output unit 81 of the main control device 8 via the hall transmission line 11 sequentially from the upper and lower cars 21 and 22 is transmitted to the car controller installed in the car 2. Similarly, the power is supplied to the input / output unit 81 of the main controller 8 via the unit 23 and the tail cord 12. Further, a car position detection signal detected between the landing detection switch 24 of the car 2 and the landing position detector 13 in the hoistway is supplied to the car controller unit 23, and the tail code 12 is similarly transmitted. It is supplied to the input / output unit 81 of the main control device 8 via the main controller 8.

The main control unit 8 comprises an input / output unit 81 and a controller unit 82. The controller unit 82 receives a call registration signal and a destination floor registration signal supplied via the input unit 81, and allocates cars. After that, the car is driven toward the target floor, and the hoisting machine 3 is drive-controlled to land and open the door.

In the double deck elevator, since there are two cars 21 and 22 at the top and bottom, the controller unit 82
For call registration from the landing, based on the driving method,
Assignment is made by selecting either the upper car 21 or the lower car 22.

If the controller 82 that has received the call registration signal from the landing on the X floor assigns the lower car 22 to the car 2 stopped on a floor other than the X floor, the controller 82 The starter 3 controls the hoisting machine 3 to cause the car 2 to travel toward the X floor, and through the steps of constant speed traveling → deceleration → stop → landing control, the allocated lower car 22 arrives at the designated (X) floor. Control to stop.

By the way, the car 2 to the designated (X) floor
Upon landing on the (lower basket 22), the controller unit 82
Since the brake control based on the car position detection signal is performed from the switching operation from the constant speed running to the decelerating running, the car 2
The vehicle slowly decelerates and stops, and passengers can use the elevator without impact.

In addition, when the controller 82 attempts to stop the hoisting machine 3 when the car 2 is landed or stopped,
Actually, a braking distance or the like based on the rotational inertia of the hoist 3 occurs, and even after the stop, the main ropes 4 suspended from the hoist 3 correspond to the main traveling direction of the car 2. Elongation or contraction changes due to running inertia due to the load of the rope itself and the load of the car 2 and the like. Therefore, from the position where the controller unit 82 has issued the stop operation command, the car 2
As described above, the distance to the position where the (lower car 22) actually stops varies slightly depending on the load of the car 2 and the like.

That is, as shown in FIG.
In the landing control on the floor, the controller unit 82 first issues a deceleration command at the point of the ± C line approaching the landing floor (X),
Next, a stop command is issued at the ± B line that is even closer, and the distance setting of a so-called wire stretch zone (range of ± B to ± A), such as the braking distance and the expansion / contraction distance of the main rope 4, is expected. Thus, the control is performed so that the car 2 can properly land and stop in the landing zone (± A).

Of course, whether the vehicle has landed in the landing zone (± A) is detected by the relative positional relationship between the landing detection switch 24 of the car and the landing position detector 13 on that floor.
If the car 2 comes out of the landing zone (± A) and stops, the re-floor adjustment operation is performed by the low speed start control of the drive motor of the hoisting machine 3 by the controller unit 82.

In the above-mentioned conventional double-deck elevator, the distance between the upper and lower cars 21 and 22 is configured to be equal to the distance between the upper and lower floors of the building. In the operation, one of the upper and lower cars 21 and 22 is set to a predetermined floor (for example, the lower car 22), and the other (the upper car 21) is landed.

[0018]

As described above, in a conventional double-deck elevator, a single landing detection switch installed is configured to stop landing on both upper and lower cars.

In the building where the elevator is installed,
If the spacing between the floors adjacent to each other is equal to the spacing between the top and bottom cars of the car, it means that the floor matching of one of the cars is the same as that of the other car, and both are within the landing zone. Can be landed.

However, in a building where an elevator is installed recently, the height between the floors, that is, the height to the ceiling depends on the purpose of use of each floor, such as a multipurpose building, depending on the use of the floor. It is often the case that the building is set arbitrarily. Also, even if the design is designed and constructed in advance so as to have the same height between floors, it is unavoidable that a slight difference actually occurs between the floor heights due to design and construction errors.

Therefore, in a building where a double deck elevator has a difference between floor heights due to an error in design and construction,
When the double operation or the semi-double operation is performed, the landing position of one of the upper and lower cars is shifted by the difference of the floor height of the building, and the car cannot smoothly move to the door opening operation.

Accordingly, the present invention provides a double-deck elevator in which even if a double-deck elevator is installed in a building with different floor heights, the upper and lower cars can be smoothly placed on the designated floor and opened. It is an object of the present invention to provide a control device.

[0023]

According to one aspect of the present invention, there is provided a control apparatus for a double-deck elevator in which two cars are connected vertically and move up and down. The upper car landing detection switch provided on the upper car, the lower car landing detection switch provided on the lower car, and the respective landing detection switches are operated in correspondence with the landing of each of the upper and lower cars. As described above, a plurality of landing position detectors installed in the hoistway, a landing call signal from the landing call button or a car call signal from the destination floor registration button on the car operation panel, and the stop specified by the signal A main control device is provided which receives the operation of the landing detection switch of the car on the floor to be floored and controls the car to land and open the door.

According to the first aspect of the present invention, since the landing detection switches are provided on each of the upper and lower cars, the main control device can
Regardless of the car call operation of the hall call or each of the upper and lower cars, the car is individually landing controlled by the position detection signal from the landing detection switch of the corresponding car, and the car is accurately and smoothly landed on the destination floor. Can be done.

According to a second aspect of the present invention, in the control device for a double-deck elevator according to the first aspect, the main control device is a landing call signal by a landing priority call button or a car call by a destination floor priority registration button of a car operation panel. When a signal is received, the landing detection switch of the car landing on the designated stop floor with the priority given to the landing call signal by the landing priority call button or the car call signal by the destination floor priority registration button is activated. Receiving the car and landing and opening the door.

According to the second aspect of the present invention, even if the floor height of each floor of the building is different and both the upper car and the lower car are registered at the same time, the call registration from the landing on the floor adjacent to the upper or lower car or the adjacent car from the upper or lower car is performed. Even if the car call is registered to the matching floor, the main controller can control the landing by giving priority to the car corresponding to the signal according to the landing priority call or the car priority call.

Therefore, for example, by a passenger using a wheelchair, a hall priority call registration with a wheelchair-specific hall button or a car priority call registration with a wheelchair-specific car operation panel is performed. Since the landing control is performed prior to the car, the elevator can be operated more smoothly in addition to the effect of the first aspect of the present invention.

[0028]

1 to 3 show an embodiment of a control device for a double deck elevator according to the present invention.
This will be described in detail with reference to FIG. The same components as those of the conventional control device for a double deck elevator shown in FIGS. 4 to 6 are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a block diagram showing an embodiment of a control device for a double deck elevator according to the present invention, and FIG. 2 is a system diagram showing a control system of the device shown in FIG.

That is, as shown in FIG. 1, the control device for the double-deck elevator according to the first embodiment includes a landing position detector 13 for determining the landing position of each stop floor in the hoistway 1. An upper car landing detection switch 24a for detecting the landing position of the upper car 21 with the landing position detector 13 is provided on the upper car 21 of the car 2 and the lower car 22 is also provided with the same. A lower car landing detection switch 24b for detecting the landing position of the lower car 22 with the landing position detector 13 is provided.

The controller 82 of the main control unit 8 sends signals from the upper car landing detection switch 24a and the lower car landing detection switch 24b to the car controller unit 2.
3 and the input / output unit 81 to control the landing of the upper car 21 and the lower car 22 individually.

Therefore, as in the prior art, the landing / door opening operation by aligning only one of the cars causes the other car to be displaced from the landing zone. The inconvenience of being unable to do so is avoided, and the landing control is performed well and smoothly so that the upper and lower cars 21, 21
22 can be properly landed and opened.

More specifically, car call registration in which the X-floor is designated by the passengers in the lower car 22 is performed. At that time, the (X + 1) -th floor is designated by the passengers in the upper car 21 almost simultaneously. When the car call registration is performed in a superimposed manner and one of the car call registrations is performed, for example, by a priority registration operation by a wheelchair passenger, the control unit 82 controls the respective car 2
A sequence for controlling landing on the floors 1 and 22 will be described with reference to the flowchart of FIG.

That is, the control unit 82 determines whether a car call has been registered from the lower car 22 to the X floor (step 51). When there is a car call registration (YE
S) Then, it is determined whether there is a car call registration from the upper car 21 to the (X + 1) floor (step 52).

If there is a car call registration on the (X + 1) floor in step 52 (YES), it is determined whether or not the registration from the lower car 22 is priority registration by a disabled person or the like (step 53).

In step 52, if there is no car call registration on the (X + 1) floor (NO), and if the lower car 22 has priority registration (YES) in step 53, the lower car 22 is driven to the designated floor and arrives. The floor / door is controlled to open (step 54).

If it is determined in step 53 that the lower car 22 is not registered with priority (NO), it is determined whether the upper car 21 is registered with priority (step 55), and if the upper car 21 is registered with priority (YES). Controls the upper car 21 to travel to the designated floor and land and open the door (step 56).

If it is determined in step 55 that the upper car 21 is not registered with priority (NO), the load Wu of the upper car and the load Wl of the lower car are detected (step 5).
7, 58), it is determined whether or not the load Wu of the upper car is greater (step 59).

In step 59, when the load Wu of the upper car 21 is large (YES), the upper car 21 is put on the floor and the door is opened with priority (step 56). When the load Wl of the lower car 22 is large (NO), the lower car 22 is controlled so as to give priority to the landing and door opening (step 54).

As described above, the controller unit 82 of the main control device 8 responds to the needs of the passengers appropriately based on the priority registration and the congestion degree of the passengers in the car detected by the load on the car. Since the selective assignment is performed and the landing control is performed based on the signal from the position detection switch of the car, the car can be smoothly landed and opened in the landing zone.

Further, in the above embodiment, the passenger at the hall presses the hall call button 9 and the call registration signal is
Main controller 8 via hall controller unit 10
When the controller 82 is supplied to the controller 82, the controller 82 determines the degree of congestion in each of the cars 21 and 22, and designates a car which has more room than the upper car 21 or the lower car 22. In order to land on the floor, a car is allocated, and the car (21 or 22) is controlled to travel toward the designated floor and land and open the door.

That is, now, the controller unit 82
For the hall call registration received from the X floor,
Assuming that the lower car 22 having room for passengers is allocated and run, the controller unit 82 includes a lower car landing detection switch 24b attached to the lower car 22 and a landing position detector 13 for determining a landing position on the X floor. And landing control is performed based on the signal between the steps.

When the controller 82 assigns the upper car 21 to the hall call registration, the controller 82 moves the upper car 21 to the X floor based on the signal from the upper car landing detection switch 24a. Is controlled so as to land and stop in the landing zone.

As described above, the controller unit 82 uses the lower car landing detection switch 24b for the lower car 22 and the upper car 21 using the upper car landing detection switch 24a according to the allocation of the cars. Is controlled to land on the designated (X) floor.

When the controller 82 of the main control unit 8 confirms that the lower car 22 has landed on the landing zone on the designated (X) floor, it simultaneously specifies the upper car 21 (X +
1) When the landing on the floor landing zone can be confirmed by the signal from the position detection switch 24a of the upper car 21, the controller unit 82 also immediately performs the door opening control on the upper car 22, It is possible to prompt the passenger to get on and off quickly.

Therefore, if it is detected that the upper car 21 is, for example, in the stretch zone and is not properly landed in the landing zone, the controller unit 82 sets the priority landing. After the getting on and off of the passengers on the lower car 22 side is completed and the door is closed, the hoisting machine 3 is controlled based on the car position detection signal from the car position detection switch 24a on the upper car 21 side, and the floor is adjusted or After the landing control is performed again, the doors are opened, so that the passengers in the upper car 21 can smoothly get off the designated (X + 1) floor following the lower car 22.

As described above, according to the present invention, the X floor and (X +
1) Even when the floor height differs between the floors and does not match the interval between the upper and lower cars 21 and 22, the controller unit 82 gives priority to the car in accordance with the priority registration by the user, etc. Since the control is performed, landing and opening of the door can be performed smoothly, and the double-deck elevator can be smoothly operated.

[0048]

According to the first aspect of the present invention, since each of the upper and lower cars has a landing detection switch, the main control device is applicable to either the landing call or the upper or lower car call registration. Since the landing can be individually controlled by the position detection signal from the landing detection switch of the car, the Dove Deck Elevator allows the upper and lower cars to smoothly land on the destination floor even in buildings with different floor heights depending on the floor. be able to.

According to the second aspect of the present invention, for example, when a passenger using a wheelchair has a car assigned to the landing priority call registration or the car priority call registration on the wheelchair dedicated car operation panel, Since the landing control is performed prior to the car, the double-deck elevator can be operated more smoothly in addition to the effect of the first aspect of the present invention.
