Description

The present invention relates to elevators, and more particularly to car door opening operations.

A car operating panel and a landing operating panel are installed in the elevator car and at the landing. Each operation panel is provided with, for example, a destination floor button displaying the number of the destination floor, a door open button and a door close button for opening and closing the car door. As an example, the passenger registers the destination floor of the car traveling on the hoistway by operating the destination floor button. As the destination floor buttons, contact-type ones such as push buttons and touch panels are widely used.

In recent years, in consideration of sanitation in elevators installed in public facilities, etc., it has become possible to register the car's destination floor by waving a hand over a photoelectric (non-contact) sensor installed on the control panel. A non-contact car operating panel that can be operated without contact is also being introduced. When the destination floor registration operation is performed in a non-contact manner as described above, there is a problem that it is difficult for the passenger to grasp whether the operation has been accepted or not because the passenger's hand does not come into contact with the operation unit.

In Patent Document 1, when a non-contact sensor placed on the control panel detects a destination floor registration operation, a demarcation line placed around the sensor and a number indicating the floor number of the destination floor light up. Disclosed is an elevator configured so that a passenger can recognize that a registration operation has been accepted.

A vertical direction Y orthogonal to the direction X and the horizontal direction Z is shown.

As shown in FIG. 1, the elevator 10 is a traction elevator having a machine room 14 at the top of a hoistway 12, and is installed in public buildings such as hospitals and nursing homes, for example. A main rope 20 is hung on a driving sheave 18 of a hoisting machine 16 installed in a machine room 14. A car 22 is connected to one end of the main rope 20, and a counterweight 24 is attached to the other end. Concatenated.

Rotational power from a motor (not shown) of the hoisting machine 16 is transmitted to the drive sheave 18 via a power transmission mechanism (not shown), and when the drive sheave 18 is rotationally driven, the main rope 20 is rotated accordingly. A car 22 that runs and is suspended from the main rope 20 moves in the vertical direction Y in the hoistway 12 while being guided by guide rails (not shown).

The building in which the elevator 10 is installed is provided with halls 26A, 26B, and 26C (hereinafter referred to as "halls 26" when there is no particular need to distinguish them) on different floors. , the car 22 repeats ascending/descending movement from the landing of the floor where it is currently landing (the landing 26C in FIG. 1) to the landing of the next destination floor (for example, the landing 26A).

FIG. 2 is a perspective view showing the configuration around the car doors 22A and 22B inside the car 22. As shown in FIG. As shown in FIG. 2, a hanging wall 22-1 positioned directly above the boarding/alighting opening 22G provided on the front side of the car 22 is provided with guidance lighting (light emitting section , first light emitting section ) LM. . A car operating panel 23 is provided on the side wall 22-2 adjacent to the entrance/exit 22G. The car operation panel 23 is an operation panel for a passenger using the elevator 10 to input the destination floor and open/close the car doors 22A and 22B. The guidance lighting LM is composed of a translucent elongated panel in which a lamp (not shown) is installed. , 22B are in operation.

FIG. 3 is a front view showing the configuration of the car operating panel 23. As shown in FIG. As shown in FIG. 3, the car operating panel 23 is provided with an operation unit 30 in the central part that performs input operations for determining the destination floor of the car 22 and for opening and closing the car doors 22A and 22B. ing. The operation unit 30 has push buttons 31A, 31B, 31C, . Immediately below the push button 31A, a door open button 32 for opening the car doors 22A and 22B and a door close button 33 for closing the car doors 22A and 22B are arranged vertically. It is arranged along Y. Since the structure of the door-close button 33 is substantially the same as that of the door-open button 32, the structure of the door-open button 32 will be mainly described in the following description, and the description of the door-close button 33 will be omitted as appropriate.

Destination floor sensor units 34A, 34B, 34C, . , and a door opening sensor section (non-contact sensor) 35 that detects light blocking in the same way as the destination floor sensor section 34 is provided. Each destination floor sensor unit 34 has a function of performing the same destination floor operation as each push button 31 adjacent on the left side without contact. Similarly, the door-open sensor unit 35 has a function of performing the same door-opening operation as the door-open button 32 without contact.

Here, each push button 31 and door open button 32 also has a function of notifying that each operation has been accepted. More specifically, as shown in FIG. 3, each of the push buttons 31A, 31B, 31C, . , L-3, . When a lamp (not shown) provided inside the push button 31 is turned on, the translucent portion L emits light. On the other hand, the door open button 32 also has the same configuration as the push button 31, and is provided with an arrow-shaped translucent portion (translucent portion) 32L on the front side. Each translucent part 32L is configured to be capable of emitting light. In this embodiment, unlike the door open button 32, the door close button 33 is not provided with a door open sensor corresponding to the button 33, but a door open sensor corresponding to the button 33 is provided. may be

Then, when the push button 31 is pressed, or when the destination floor sensor unit 34 detects an obstacle such as a hand, the destination floor (call) is registered and the translucent portion L lights up. Accordingly, when an input operation is performed via each button 31, the user can visually confirm the reception status of each input operation. Similarly, when the door open button 32 is pressed, or when the door sensor unit 35 detects light blocking by a shield such as a hand, the translucent unit 32L lights up. Although the push button 31 and the door open button 32 are used in this embodiment, a touch sensor or the like may be used.

Since the destination floor sensor unit 34 and the door opening sensor unit 35 described above have substantially the same configuration, the following description will mainly focus on the configuration of the destination floor sensor unit 34, and the door opening sensor unit 35 will be described as appropriate. Description is omitted.

Each destination floor sensor unit 34 is provided with a substantially rectangular hole having both ends curved in the same direction. 37B, 37C, . In each rectangular hole of each destination floor sensor unit 34, a reflective photoelectric sensor in which a light projector and a light receiver are integrated is housed. The presence or absence of an object is detected based on the change in

Here, FIG. 4 is a sectional view schematically showing the positional relationship between the destination floor sensor section 34 and the detection area P. As shown in FIG. In FIG. 4, the detection area P is indicated by hatching, and the configuration other than the destination floor sensor section 34 and the detection area P is omitted as appropriate. As shown in FIG. 4, the destination floor sensor unit 34 is configured to adjust the amount of light received by the light receiver (sensitivity of the sensor) and detect light blocking by an object (shield) in a preset detection area P. be done. As shown in FIG. 4, the detection area P is located at a position X2 in the horizontal direction X from a position at a distance X1 in the horizontal direction X from the destination floor sensor unit 34 when 0 mm≦X1<X2. is set to be a spatial region including up to

As shown in FIG. 3 , the car operating panel 23 further has a display section 44 . The display unit 44 is composed of, for example, a liquid crystal display, and displays, for example, the direction of movement (up and down) of the car 22, the floor the car 22 passes through, and other information to be notified to passengers. The display unit 44 is provided above the operation unit 30 at a position that is easy for passengers to see. As indicated by the dashed line in FIG. 3, the car operating panel 23 incorporates a speaker (sound generator) SP for outputting sound. The speaker SP has a role of generating sounds for informing passengers of the opening and closing operations of the car doors 22A and 22B.

The car operating panel 23 configured as described above is electrically connected to a control device 46 (see FIG. 1) installed in the machine room 14 (see FIG. 1). The control device 46 is a computer that controls the operation of the car 22 based on the destination floor registration performed in response to the input operation performed via the car operating panel 23, etc., and includes a CPU, a memory, and the like. . The memory stores, for example, drive control of the hoisting machine 16, opening/closing control of the car doors 22A and 22B, lighting control of the translucent portion L of each push button 31, translucent portion 32L of the door opening button 32, and guidance lighting LM, Various control programs are stored for controlling the speaker SP and the like. Smooth operation of the elevator 10 by the control device 46 is realized by the CPU reading out these programs from the memory and executing them.

In the elevator 10, the control device 46 also controls the opening and closing of the car doors 22A and 22B. The memory of the control device 46 stores a control program for registering the destination floor of the car 22 . In the control device 46, the CPU reads out the control program from the memory and executes the door open mode and the door closed mode. Here, the door open mode is a mode for moving the car doors 22A and 22B in the door opening direction and keeping the doors 22A and 22B in the open state. Further, the door closing mode is a mode for moving the car doors 22A and 22B in the door closing direction, in other words, in the direction of the fully closed state.

Here, the flow of opening/closing control of the car doors 22A and 22B using the door opening sensor section 35 in the control device 46 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of opening/closing control of the car doors 22A and 22B by the control device 46 when the door opening sensor section 35 detects light blocking.

As shown in FIG. 5, the controller 46 determines whether or not the door can be opened when the door sensor 35 detects light blocking (steps S1 and S2). The state in which the door can be opened includes a state in which the car 22 has landed on the landing 26 and there is no need to forcibly maintain the door closed state. As a result, even if the door opening sensor section 35 detects light blocking, the notification sound does not sound when the car 22 is not in a state in which the door can be opened. The lighting LM does not flicker either. Therefore, passengers in the car 22 are not given unnecessary guidance.

In step S2, when the control device 46 determines that the door can be opened, the door open mode is executed after a predetermined waiting time has elapsed except during execution of the door closed mode (steps S3, S4, S5). On the other hand, when the door closed mode is being executed, the control device 46 executes the door open mode without waiting for the predetermined waiting time to elapse (steps S3 and S5).

In step S5, the control device 46 generates a predetermined notification sound through the speaker SP when executing the door-open mode, and also controls the light-transmitting portion 32L (see FIG. 3) of the door-open button 32 and the hanging wall 22-. 1 blinks the guide light LM (see FIG. 2). The predetermined notification sound is, for example, an intermittent sound of "beep-beep-beep...". As a result, the detection status of the door opening sensor section 35 can be easily grasped even in a situation where the translucent portion 32L of the door opening button 32 is difficult to see while the passenger holds his/her hand over the door opening sensor section 35 .

Instead of the intermittent sound, a continuous sound or a voice guidance indicating that the car doors 22A and 22B (see FIG. 2) are being opened may be broadcast through the speaker SP. By generating a predetermined notification sound during execution of the door open mode as described above, for example, even when the door open mode is executed due to the detection of passenger's luggage by the door open sensor unit 35, the door opens. Passengers can quickly notice that the sensor section 35 is detecting the luggage. In addition, there is an advantage that the door-open mode can be terminated quickly by the passenger withdrawing the luggage from the detection area of the door-open sensor section 35, and the operation of the elevator 10 can be made smooth.

Next, as shown in FIG. 5, when the door opening sensor section 35 stops detecting light shielding (step S6), the control device 46 controls the timing from the timing when light shielding ceases to be detected (first non-detection timing) to the first detection timing. After a predetermined period of time (for example, 3 seconds) has elapsed, the door closing mode is executed (steps S7 and S15).

With the above configuration, even if the door opening sensor 35 does not detect light shielding because the passenger carelessly moves his or her hand over the detection area of the door opening sensor 35, the first predetermined time elapses. Door closed mode is initiated only afterward.

Here, when the door opening sensor section 35 stops detecting light blocking in step S6 described above, in other words, at the timing when light blocking is no longer detected, the controller 46 controls the notification sound and guidance lighting generated in step S5. It is preferable to stop blinking the LM. As a result, the passenger can immediately notice that the door opening sensor section 35 has not detected the light blocking.

Further, the control device 46 terminates the door-open mode being executed in step S5 after the first predetermined time has elapsed in step S7, in other words, the control device 46 continues the operation until transition to the door-closed mode in step S15. . As a result, the car doors 22A and 22B can be kept open until the first predetermined time elapses.

According to the above configuration, while keeping the car doors 22A and 22B in the open state, when the passenger wants to extend the door open state, it is easy to take measures such as holding the hand over the detection area of the door opening sensor section 35 again. It is possible to prevent the door closing mode from being executed against the passenger's intention.

On the other hand, as shown in FIG. 5, when the door opening sensor section 35 detects light again before the first predetermined time elapses (step S8), the control device 46 sets the predetermined waiting time (for example, 0.00). 3 seconds) (step S9), the door open mode is executed (step S10).

In step S10, when the door open mode is executed, the control device 46 generates a notification sound through the speaker SP and turns on the guide lighting LM and the translucent portion 32L of the door open button 32 in the same manner as in step S5. blink. As a result, the passenger can easily grasp the light shielding detection state by the door opening sensor section 35, as in the case of step S5.

Then, as shown in FIG. 5, when the door opening sensor section 35 stops detecting light (step S11), the control device 46 measures the time from the timing when the detection stops (second non-detection timing). After the measured time (hereinafter referred to as "measured time") has passed a second predetermined time (for example, 3 seconds) (step S12), the door closing mode is executed (step S15).

Here, the control device 46 causes the notification sound generated via the speaker SP in step S10, the guidance lighting LM and the blinking of the translucent portion 32L of the door opening button 32 to be activated by the door opening sensor portion 35 in step S11. Terminates when light shielding detection by is stopped. Therefore, the passenger can easily understand that the door opening sensor section 35 does not detect light blocking. On the other hand, the control device 46 continues to execute the door open mode that is being executed in step S10 until the second predetermined time has elapsed in step S12 and the process transitions to step S15. Thereby, the car doors 22A and 22B can be kept open until the second predetermined time elapses. As a result, when it is desired to extend the door-open state, it is easy for the passenger to place his or her hand over the detection area of the door-open sensor section 35 before the door-closed mode is executed.

As shown in FIG. 5, the control device 46 resets the measured time measured in step S12 when the door opening sensor unit 35 detects light again before the second predetermined time elapses (step S13). That is, the measurement time is set to 0 seconds (step S14). As a result, even if the door opening sensor unit 35 stops detecting light shielding after redetecting light shielding in step S13, after that, the second predetermined time (for example, 3 seconds) elapses in step S12 before the door is closed. mode can be run.

Subsequently, as shown in FIG. 5, the control device 46 returns to step S10, executes the door open mode again, generates a notification sound, and turns on the guide lighting LM and the translucent portion 32L of the door open button 32. blink.

Then, when a second predetermined time (for example, 3 seconds) elapses without the sensor unit 35 detecting light shielding again from the timing at which the door sensor unit 35 stops detecting light shielding (steps S11, S12), the door closing mode is executed (step S15), and a series of opening/closing control processing for the car doors 22A and 22B is completed.

As described above, when the door opening sensor unit 35 changes from the detection state in which the light is detected during the door open mode to the non-detection state in which the light is not detected, the controller 46 changes from the detection state to the non-detection state in which the light is not detected. The door closing mode is executed after a first predetermined time elapses from the first non-detection timing at which the state changes to the non-detection state. Further, when the door opening sensor unit 35 detects the light shielding again before the first predetermined time elapses, the second predetermined time elapses from the second non-detection timing at which the door open sensor unit 35 does not detect the light shielding again after the redetection. After that, the door closed mode is executed.

As a result, even if the passenger moves his or her hand out of the detection area of the door opening sensor section 35 while holding the hand or the like over the door opening sensor section 35, the door closing mode is not executed until the predetermined time has elapsed. . Then, when the light is detected again by putting the hand over it again before the predetermined time elapses, the door closing mode is not executed until the predetermined time elapses after the light is not detected again.

For this reason, when the passenger unintentionally moves the hand held over the door opening sensor 35 outside the detection area, the door sensor 45 does not detect the light shielding, and the door is not detected. Even if the closed mode is not started and the non-detection is made, the door open state can be maintained by, for example, holding the hand over the door open sensor section 35 again. Therefore, it is not necessary to continuously hold the hand over the door opening sensor portion 35 while the car doors 22A and 22B are held in the open state, and the door open state can be maintained by holding the hand over the door opening sensor portion 35 from time to time. There is also the advantage of

According to the elevator 10 of the present embodiment, the car doors 22A and 22B are opened and a predetermined (intermittent) sound is generated based on light shielding detection by the door opening sensor section 35 . As a result, the passenger can easily grasp the detection state of the door opening sensor section 35 even when the passenger holds his or her hand over the door opening sensor section 35 . In addition, when the passenger unintentionally causes the door sensor unit 35 to detect light blocking, the passenger can quickly notice that the sensor unit 35 is reacting (detecting light blocking). .

In steps S7 and S12 of the above embodiment, while waiting for the first predetermined time and the second predetermined time, respectively, the control device 46 emits a sound pattern different from the sound pattern generated in steps S5 and S10 from the speaker SP. may occur. As a result, there is an advantage that the passenger can easily understand that the door opening sensor section 35 does not detect light shielding and that the car doors 22A and 22B will open soon.

In the above embodiment, in steps S5 and S10, the control device 46 generates an intermittent sound through the speaker SP during execution of the door open mode, Although both are flashed, only one of them may be flashed together with the intermittent sound. Alternatively, the control device 46 may generate only an intermittent sound through the speaker SP, and may not blink the guidance lighting LM and the translucent portion 32L.

In the above embodiment, an example in which both the first predetermined time and the second predetermined time are set to 3 seconds has been described. and may be set shorter than 3 seconds. Also, both predetermined times may be set to different lengths.

The present invention can also be implemented in aspects with various improvements, modifications, or variations based on the knowledge of those skilled in the art without departing from the spirit of the invention. Moreover, any invention specifying matter may be replaced with another technique within the scope of producing the same action or effect.
