Description

Embodiments of the invention relate to a double deck elevator system.

Conventionally, when a double-deck elevator is used for exclusive use, such as for the purpose of transporting luggage, without responding to hall calls, only one of the upper car (upper car) and lower car (lower car) is used. As workers are bringing in cargo and getting on board, the other basket, which is not being used, remains empty.
On the other hand, as disclosed in Patent Document 1, for example, in order to transport cargo by loading it into both the upper and lower cars, when a hall call button is operated on a car stopping floor, both the upper and lower cars are moved to this floor. There are some that implant the following in sequence.

Japanese Patent Application Publication No. 2012-254854

However, with the above configuration in which the upper and lower cars are moved by pressing the hall call button, for example, after a worker gets into one of the cars, a passenger or the like may press the hall call button on the floor where the car stops. There is a risk that the work of the workers may be hindered or dangerous.
Additionally, when performing group management control, a configuration is often used in which a single hall call button is installed between multiple cars at the landing, and in such a configuration, the hall call button is pressed as described above. Therefore, it is not possible to support a configuration in which the upper and lower cars are placed on the floor one after another.

The problem to be solved by the present invention is to provide a double-deck elevator system that can perform dedicated operation without responding to hall calls by effectively utilizing both the upper and lower cars.

The double-deck elevator device of the embodiment includes a first car and a second car connected in the up-and-down direction, a door close button installed in the first and second cars, and the first car. and an operation mode switching section that switches the operation mode of the second car between a normal operation mode and a dedicated operation mode that does not respond to hall calls; By operating the door close button on one of the second cars, that one car is moved from the floor on which it is currently landing, and the other of the first and second cars is moved from the floor on which it is currently landing. A control unit is provided to cause the moved car to land on the same floor as the one on which it has landed.

The double-deck elevator device of the embodiment includes a first car and a second car connected in the up-and-down direction, a load detection section that detects the carrying loads of the first and second cars, and the first car and the second car. an operation mode switching unit that switches the operation mode of the first and second cars between a normal operation mode and a dedicated operation mode that does not respond to hall calls; and when the operation mode is the dedicated operation mode, the load detection unit When it is determined that the work on one of the first and second cars is completed based on the load detected by the section, the floor on which that one car is currently landing; and a control unit for causing the other of the first and second cars to land on the same floor as the moved car has landed on.

Hereinafter, embodiments will be described using the drawings.
FIG. 1 is a diagram showing an example of the overall configuration of a double deck elevator apparatus according to an embodiment.
As shown in FIG. 1, a double-deck elevator device (hereinafter also simply referred to as "elevator") 1 according to the present embodiment has an outer car 2 that moves up and down in a hoistway, and an outer car 2 that is connected in the up-and-down direction inside the outer car 2. an upper car 3 and a lower car 4 (sometimes referred to as upper and lower cars), a car drive unit 5 installed at the top of the hoistway to raise and lower the outer car 2, and a car drive unit 5 installed at the top of the outer car 2, etc. An upper and lower car drive unit 6 that adjusts the positions of the upper and lower cars within the outer car 2 as necessary; and a car drive unit 6 that is installed on the top of the hoistway and electrically connected to the upper and lower cars via a tail cord (not shown); An elevator control device 7 is provided as a control unit that controls the elevator car driving unit 5 and the upper and lower car driving units 6 to control the elevation of the upper and lower cars.

The car drive unit 5 is a rope-type drive mechanism, and includes a rope 5a whose one end is connected to the outer car 2, a counterweight 5b connected to the other end of the rope 5a, and a rope 5a. It includes a sheave 5c to be wrapped around and a drive source 5d for rotating the sheave 5c. When the drive source 5d rotates the sheave 5c, the outer car 2 moves up and down while being guided by a rail (not shown) in the hoistway. Note that the car drive unit 5 is not limited to the rope-type drive mechanism, and may include, for example, a linear motor-type or hydraulic drive mechanism.

Inside the upper car 3, there are two elevator operation modes: a normal operation mode (sometimes simply referred to as normal operation) in which the elevator responds to hall calls (platform calls), and a hall operation mode for the purpose of preferential transportation of luggage, etc. An operation mode changeover switch (sometimes referred to as dedicated operation SW) 31, which accepts an operation when switching between a dedicated operation mode that does not respond to calls (sometimes simply referred to as dedicated operation), selects the destination floor of the upper car 3. Operations for registering a designated destination floor call, that is, the car call button 32 that accepts the car call operation, the upper car door open button 33a that accepts the operation to open the door of the upper car 3, and the operation to close the door of the upper car 3. An upper car door close button 33b for receiving the load, and an in-car load detector 34 as a load detection section for detecting the load inside the upper car 3 are provided.

Similarly, in the lower car 4, there is registered an operation mode changeover switch 41 that accepts the operation when switching the elevator operation mode between normal operation and dedicated operation, and a destination floor name that specifies the destination floor of the lower car 4. a lower car door open button 43a that accepts an operation to open the door of the lower car 4; a lower car door close button 43b that accepts an operation to close the door of the lower car 4; An in-car load detector 44 is provided as a load detection section for detecting the load inside the car.

When the operation mode changeover switch 31 or the operation mode changeover switch 41 is turned off, the elevator control device 7, as an operation mode switching section, switches the operation mode of the elevator to the normal operation mode. On the other hand, when the operation mode changeover switch 31 or the operation mode changeover switch 41 is turned on, the elevator control device 7, as an operation mode switching section, switches the operation mode of the elevator to the dedicated operation mode.

In this embodiment, when the operation mode of the elevator is switched to dedicated operation, the upper car door close button 33b in the upper car 3 or the lower car door close button 43b in the lower car 4 is operated. Then, the upper car 3 and the lower car 4 can be sequentially landed on the landing area of the work floor related to loading or unloading luggage.

Next, the operation of the double deck elevator system according to this embodiment will be explained. FIG. 2 is a flowchart illustrating a first example of dedicated operation when transporting luggage by the double-deck elevator apparatus according to the embodiment. Here, we will explain an example in which the cargo is carried in in the order of lower car 4 and upper car 3, and the cargo is carried out in the order of upper car 3 and lower car 4, and the door close buttons of the upper and lower cars are used for control in dedicated operation. .

First, during normal operation, while the lower car 4 is on the platform of the floor where cargo loading work is carried out (loading work floor), a worker turns on the operation mode changeover switch 41 in the lower car 4. When switching to the state (S11), the elevator control device 7 switches the operation mode of the elevator to the dedicated operation, and leaves the lower car 4 on standby with the door open (S12). Then, the upper car 3 becomes on standby with its door closed and does not respond to hall calls.

In this state, the worker starts loading cargo into the lower car 4 whose door is open. When the loading of the cargo into the lower car 4 is completed, the worker presses the lower car door close button 43b inside the lower car 4 once and gets off the lower car 4 (S13), and after a certain period of time has elapsed, the worker exits the elevator. The control device 7 automatically closes the door of the lower car 4 (S14).

When this door closing is completed, the elevator control device 7 slides the upper and lower cars, that is, causes the upper and lower cars to land on the work floor one after another, and moves the lower car 4 one floor below the loading work floor. At the same time, the upper car 3 is placed on the carry-in work floor where the worker is, and the upper car 3 is placed on standby with the door open (S15).

In this state, when moving to another floor, that is, the floor where the load carrying out work is performed (unloading work floor) (Yes in S16), the worker starts carrying the load into the upper basket 3. When the loading of the cargo into the upper car 3 is completed, the worker operates the car call button 32 in the upper car 3 corresponding to the floor to which the work is to be carried out, thereby registering the destination floor call.

After this operation, after a certain period of time has elapsed, or when the upper car door close button 33b in the upper car 3 is operated and door closing is completed (S17), the elevator control device 7 The upper car 3 is placed on the floor, and the upper car 3 that has arrived at the destination floor is placed on standby with the door open, and the lower car 4 is placed on standby with the door closed (S18).

In this state, the worker starts carrying out the cargo from the upper car 3 whose door is open. Once the cargo has been removed from the upper car 3, the worker presses the upper car door close button 33b inside the upper car 3 once and gets off the upper car 3 (S19). The control device 7 automatically closes the door of the upper car 3 (S20).

When this door closing is completed, the elevator control device 7 causes the upper and lower cars to slide again so that the upper car 3 lands on the floor one floor above the unloading work floor and waits for the door to be closed, and the lower car 4 The lower car 4 is placed on the unloading work floor where the worker is present, and the lower car 4 is placed on standby with the door open (S21).

In this state, the worker starts carrying out the cargo from the lower basket 4. When the unloading of the cargo from the lower car 4 is completed (S22) and the worker turns off the operation mode changeover switch 41 in the lower car 4, the elevator control device 7 changes the operation mode to normal operation. It is restored (S23).

FIG. 3 is a flowchart illustrating a second example of dedicated operation during cargo transportation by the double-deck elevator apparatus according to the embodiment. Here, we will explain an example in which cargo is carried in in the order of upper car 3 and lower car 4, and carried out in order of lower car 4 and upper car 3, and the door close buttons of the upper and lower cars are used for control in dedicated operation. .

First, during normal operation, while the upper car 3 is on the platform of the floor where cargo is carried in (loading work floor), a worker turns on the operation mode changeover switch 31 in the upper car 3. When switching to the state (S31), the elevator control device 7 switches the operation mode of the elevator to the exclusive operation, leaves the upper car 3 on standby with the door open (S32). Then, the lower car 4 becomes on standby with the door closed and does not respond to hall calls.

In this state, the worker starts loading cargo into the upper basket 3 whose door is open. When the loading of the cargo into the upper car 3 is completed, the worker presses the upper car door close button 33b in the upper car 3 once and gets off the upper car 3 (S33), and after a certain period of time has passed, the worker leaves the elevator. The control device 7 automatically closes the door of the upper car 3 (S34).

When this door closing is completed, the elevator control device 7 causes the upper and lower cars to slide so that the upper car 3 lands on the floor one floor above the carry-in work floor and waits for the door to be closed, and the lower car 4 The lower car 4 is placed on the loading work floor where the worker is located, and the lower car 4 is placed on standby with the door open (S35).

In this state, when moving to another floor, that is, the carry-out work floor (Yes in S36), the worker starts carrying the cargo into the lower basket 4. When the loading of the cargo into the lower car 4 is completed, the worker operates the car call button 42 in the lower car 4 corresponding to the floor to which the work is to be carried out, thereby registering the destination floor call.

After this operation, after a certain period of time has elapsed, or when the lower car door close button 43b in the lower car 4 is operated and door closing is completed (S37), the elevator control device 7 The lower car 4 is placed on the floor, the lower car 4 is placed on standby with the door open, and the upper car 3 is placed on standby with the door closed (S38).

In this state, the worker starts carrying out the cargo from the upper basket 3. When the unloading of the cargo from the upper car 3 is completed (S42) and the worker turns off the operation mode changeover switch 31 in the upper car 3, the elevator control device 7 changes the operation mode to normal operation. It is restored (S43).

FIG. 4 is a flowchart illustrating a third example of dedicated operation during cargo transportation by the double-deck elevator apparatus according to the embodiment. In this example, cargo is carried in in the order of lower car 4 and upper car 3, and carried out in order of upper car 3 and lower car 4, and the car load detectors of the upper and lower cars are used for control in dedicated operation. explain.

First, during normal operation, while the lower car 4 is on the platform of the floor where cargo loading work is carried out (loading work floor), a worker turns on the operation mode changeover switch 41 in the lower car 4. When switching to the state (S51), the elevator control device 7 switches the operation mode of the elevator to the dedicated operation, and leaves the lower car 4 on standby with the door open (S52). Then, the upper car 3 becomes on standby with its door closed and does not respond to hall calls.

In this state, the worker starts loading cargo into the lower car 4 whose door is open. When the loading of the baggage into the lower car 4 is completed, the worker gets off the lower car 4 (S53), and during this loading process, the in-car load detector 44 of the lower car 4 detects that the load has not been loaded into the lower car 4. When it detects a change in the load of more than a predetermined value indicating that the load has been carried in, and the detected value of the load does not change more than the predetermined value even after a certain period of time has elapsed since this detection, the elevator control device 7 It is assumed that the loading of the luggage into the car 4 has been completed, and the door of the lower car 4 is automatically closed (S54).

When this door closing is completed, the elevator control device 7 causes the upper and lower cars to slide, so that the lower car 4 lands on the floor one floor below the carry-in work floor and waits for the door to be closed, and the upper car 3 The upper car 3 is placed on the carry-in work floor where the worker is located, and the upper car 3 is placed on standby with the door open (S55).

In this state, when moving to another floor, that is, the floor where the load carrying out work is performed (unloading work floor) (Yes in S56), the worker starts carrying the load into the upper basket 3. When the loading of the cargo into the upper car 3 is completed, the worker operates the car call button 32 in the upper car 3 corresponding to the floor to which the work is to be carried out, thereby registering the destination floor call.

After this operation, after a certain period of time has elapsed, or when the upper car door close button 33b in the upper car 3 is operated and door closing is completed (S57), the elevator control device 7 The upper car 3 is placed on the floor, the upper car 3 is placed on standby with the door open, and the lower car 4 is placed on standby with the door closed (S58).

In this state, the worker starts carrying out the cargo from the upper car 3 whose door is open. When the unloading of the baggage from the upper car 3 is completed, the worker gets off the upper car 3 (S59), and during this unloading process, the car load detector 34 of the upper car 3 detects that the load from the upper car 3 When a change in the load greater than a predetermined value indicating that the load has been carried out is detected, and the detected value of the load does not vary more than the predetermined value even after a certain period of time has elapsed since this detection, the elevator control device 7 It is assumed that the unloading of the cargo from the car 3 has been completed, and the door of the upper car 3 is automatically closed (S60).

When this door closing is completed, the elevator control device 7 causes the upper and lower cars to slide again so that the upper car 3 lands on the floor one floor above the unloading work floor and waits for the door to be closed, and the lower car 4 The lower car 4 is placed on the unloading work floor where the worker is present, and the lower car 4 is placed on standby with the door open (S61).

When the unloading of the cargo from the lower car 4 is completed (S62) and the worker turns off the operation mode changeover switch 41 in the lower car 4, the elevator control device 7 changes the operation mode to normal operation. It is restored (S63).

FIG. 5 is a flowchart illustrating a fourth example of dedicated operation during cargo transportation by the double deck elevator apparatus according to the embodiment. In this example, the cargo is carried in in the order of upper car 3 and lower car 4, and the cargo is carried out in the order of lower car 4 and upper car 3. An example used for control will be explained.

First, during normal operation, while the upper car 3 is on the platform of the floor where cargo is carried in (loading work floor), a worker turns on the operation mode changeover switch 31 in the upper car 3. When switching to the state (S71), the elevator control device 7 switches the operation mode of the elevator to the dedicated operation, leaves the upper car 3 on standby with the door open (S72). Then, the lower car 4 becomes on standby with the door closed and does not respond to hall calls.

In this state, the worker starts loading cargo into the upper basket 3 whose door is open. When the loading of the baggage into the upper car 3 is completed, the worker gets off the upper car 3 (S73). When a change in the load greater than a predetermined value indicating that the load has been carried in is detected, and the detected value of the load does not vary more than the predetermined value even after a certain period of time has elapsed since this detection, the elevator control device 7 It is assumed that the loading of the luggage into the car 3 is completed, and the door of the upper car 3 is automatically closed (S74).

When this door closing is completed, the elevator control device 7 causes the upper and lower cars to slide so that the upper car 3 lands on the floor one floor above the carry-in work floor and waits for the door to be closed, and the lower car 4 The lower car 4 is placed on the loading work floor where the worker is located, and the lower car 4 is placed on standby with the door open (S75).

It is restored (S83).

According to the embodiment described above, in the double-deck elevator device in which the upper car 3 and the lower car 4 are integrated, during cargo loading work during dedicated operation, the upper and lower cars are slid to the loading work floor by an operation inside the car. In addition, in the load carrying out operation during this dedicated operation, the upper and lower cars can be slid in operation by operations inside the car, and the cargo can be sequentially landed on the carrying out work floor. That is, by the dedicated operation described above, one of the upper car 3 and lower car 4 is moved or evacuated from the floor on which it is currently landing, and the other of the upper car 3 and lower car 4 is moved to the floor on which it is currently landing. It is possible to land the car on the same floor that the car was on.

As a result, during dedicated operation, two cages can be used together with a simple operation by one worker, making it possible to transport a large amount of luggage and the like in a short period of time in one go up and down. That is, both the upper and lower cars can be effectively utilized to perform dedicated operation in which the hall does not respond to calls.

In addition, in this embodiment, a configuration is realized in which the upper and lower cars are slid by operation inside the car, so that erroneous operations by others outside the car may hinder or pose a danger to the worker's work. It is possible to avoid the risk of

Furthermore, in this embodiment, the number of times the upper and lower cars are raised and lowered can be reduced, so an energy saving effect can be expected. Furthermore, by using pre-installed operation buttons inside the car to sequentially place the upper and lower cars on the work floor, it is possible to carry out efficient cargo transportation while suppressing increases in equipment costs.

In addition, in this embodiment, the upper and lower cars can be slid by a simple operation as described above without leaving anyone in the car, so when the other car is evacuated and the door is open. You can avoid being trapped.
In the above embodiment, an example was explained in which the upper and lower cars are slid by pressing the car inner door close button once during loading or unloading work. After completing the loading or unloading work, you can press the car door close button twice to cause the upper and lower cars to slide. The upper and lower cars may be slid in combination with the operation of other buttons within the car, for example, a specific car call button within the car.

Further, in the above embodiment, the operation mode is switched between the normal operation mode and the dedicated operation mode by operating the operation mode changeover switch 31 in the upper car 3 or the operation mode changeover switch 41 in the lower car 4. As described above, the present invention is not limited to this. For example, the worker may transmit an operation mode switching signal, which is an operation mode switching command, by operating a mobile terminal device at the start of work, and the elevator control device 7 may receive this signal. The driving mode may be switched.
