Description

The present invention relates to an elevator, and more particularly to a door opening operation of a car door.

A car operation panel and a landing operation panel will be installed in the elevator car and on the landing. Each operation panel is provided with, for example, a destination floor button displaying numbers on the destination floor, and a door open button and a door close button for opening and closing the car door. As an example, the passenger operates the destination floor button to register the destination floor of the car moving on the hoistway. Contact-type buttons such as push buttons and touch panels are widely used for the destination floor buttons.

In recent years, in elevators installed in public facilities, etc., in consideration of hygiene, the operation of registering the destination floor of the car is performed by holding a hand over a photoelectric (non-contact type) sensor placed on the operation panel. Non-contact type car operation panels that can be operated non-contact are also being introduced. When the operation of registering the destination floor is performed in a non-contact manner in this way, there is a problem that it is difficult for the passenger to grasp whether or not the operation is accepted because the passenger's hand does not come into contact with the operation unit.

In Patent Document 1, when a non-contact sensor arranged on the operation panel detects a registration operation of the destination floor, a dividing line arranged around the sensor and a numerical portion indicating the number of floors of the destination floor are lit. This discloses an elevator configured so that passengers can know that the registration operation has been accepted.

JP-A-2019-142686

As in the elevator described in Patent Document 1, if a non-contact sensor is used to open the door of the car, the passenger holds his / her hand over the non-contact sensor to block light from the sensor. It is necessary to keep detecting. At this time, even if the light emitting portion provided around the non-contact sensor is turned on, a shield such as a hand holding the sensor tends to obstruct the passenger's field of vision. Therefore, it may be difficult for the passenger to visually recognize the light emitting unit arranged around the non-contact sensor, and there is a problem that the passenger cannot sufficiently grasp the detection state of the sensor.

The present invention provides an elevator that allows passengers to easily grasp the detection state of the non-contact type sensor when the door opening operation of the car door is performed non-contactly by causing the non-contact type sensor to detect a shield. The purpose.

The elevator of the present invention is an elevator configured so that the door opening operation of the car door provided in the car can be operated non-contactly, and detects shading to perform the door opening operation of the car door non-contactly. A non-contact sensor, a sound generator that generates a sound to notify the open / closed state of the car door, and a door opening mode that opens the car door based on the light-shielding detection of the non-contact sensor are executed, and the door is opened. The sound generating unit is provided with a control unit that generates a predetermined sound in the open mode, and the control unit does not detect from the detection state in which the non-contact sensor detects shading during the execution of the door open mode. The predetermined sound is stopped at the first non-detection timing that changes to the non-detection state, and the door opening mode is terminated after the lapse of the first predetermined time from the first non-detection timing .

In the elevator of the present invention, the control unit executes a door closing mode in which the car door is closed after the lapse of the first predetermined time from the first non-detection timing, and the non-contact sensor is activated before the lapse of the first predetermined time. When the light-shielding is re-detected, the door closing mode may be executed after a second predetermined time has elapsed from the second non-detection timing at which the non-contact sensor stops detecting the light-shielding after the re-detection.

The elevator of the present invention may include a light emitting unit that notifies by light emission that the control unit is executing the door open mode.

According to the elevator of the present invention, the car door is opened and a predetermined sound is generated based on the light-shielding detection by the non-contact sensor. As a result, the passenger can easily grasp that the sensor detects the shield even when the passenger holds a shield such as a hand over the non-contact sensor.

It is an overall block diagram of the elevator which is one Embodiment of this invention. It is a perspective view which shows the structure of the car operation panel installed in the car included in FIG. It is a figure which enlarges and shows the structure of the whole car operation panel included in FIG. 2, and a part structure of the operation panel. It is sectional drawing which shows typically the positional relationship between the destination floor sensor part and the detection area included in FIG. It is a flowchart which shows the flow of opening / closing control of a car door through a car operation panel shown in FIG.

Hereinafter, the elevator 10 according to an embodiment of the present invention will be described with reference to the drawings. In each figure, "Z" shown in the figure indicates a horizontal direction Z parallel to the axial direction of the drive sheave 18, "X" indicates a horizontal direction X orthogonal to the horizontal direction Z, and "Y" indicates a horizontal direction. It is assumed that the vertical direction Y orthogonal to the direction X and the horizontal direction Z is indicated.

As shown in FIG. 1, the elevator 10 is a traction type elevator having a machine room 14 at the uppermost part of the hoistway 12, and is installed in a public building such as a hospital or a nursing care facility, for example. A main rope 20 is hung on the drive sheave 18 of the hoisting machine 16 installed in the 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. It is connected.

The rotational power from the motor (not shown) of the hoisting machine 16 is transmitted to the drive sheave 18 via the power transmission mechanism (not shown), and when the drive sheave 18 is rotationally driven, the main rope 20 is moved accordingly. The car 22 that travels and is suspended from the main rope 20 is guided by a guide rail (not shown) and moves in the hoistway 12 in the vertical direction Y.

In the building where the elevator 10 is installed, landings 26A, 26B, and 26C (hereinafter, appropriately referred to as "landing 26" if it is not necessary to distinguish them) are provided for each different floor, and the elevator 10 is in operation. The car 22 repeatedly moves up and down from the landing on the currently landing floor (landing 26C in FIG. 1) to the landing on the next destination floor (for example, landing 26A).

FIG. 2 is a perspective view showing the configuration around the car doors 22A and 22B in the car 22. As shown in FIG. 2, a guide lighting (light emitting unit) LM is provided on the hanging wall 22-1 located directly above the entrance 22G provided on the front side of the car 22. Further, a car operation panel 23 is provided on the sleeve wall 22-2 adjacent to the entrance / exit 22G. The car operation panel 23 is an operation panel for passengers using the elevator 10 to perform input operations on the destination floor and open / close operations of the car doors 22A and 22B. Further, the guidance lighting LM is composed of an elongated panel having a translucent property in which a lamp (not shown) is installed inside. For example, the car door 22A is turned on when the car doors 22A and 22B are opened and closed to give passengers the car door 22A. , 22B has a role of notifying that it is in operation.

FIG. 3 is a front view showing the configuration of the car operation panel 23. As shown in FIG. 3, the car operation panel 23 is provided with an operation unit 30 having a role of performing an input operation for determining the destination floor of the car 22 and an opening / closing operation of the car doors 22A and 22B in the central portion. ing. In the operation unit 30, push buttons 31A, 31B, 31C, ... (Hereinafter, when it is not necessary to distinguish them, they are referred to as push buttons "31") are arranged at equal intervals along the vertical direction Y. Immediately below the push button 31A, a door opening button 32 for performing the door opening operation of the car doors 22A and 22B and a door closing button 33 for performing the door closing operation of the doors 22A and 22B are respectively in the vertical direction. Arranged along Y. Since the configuration of the door opening button 33 is substantially the same as that of the door opening button 32, the configuration of the door opening button 32 will be mainly described in the following description, and the description of the door closing button 33 will be omitted as appropriate.

To the right of each push button 31 and door open button 32, there are destination floor sensor units 34A, 34B, 34C, ... (Hereinafter referred to as sensor "34" if there is no particular need to distinguish) and the destination. Similar to the floor sensor unit 34, a door opening sensor unit (non-contact type sensor) 35 that detects light blocking is provided. Each destination floor sensor unit 34 has a function of performing the same destination floor operation as each push button 31 adjacent to the left side in a non-contact manner. Similarly, the door open sensor unit 35 has a function of performing the same door open operation as the door open button 32 in a non-contact manner.

Here, each push button 31 and the door open button 32 also have a function of notifying that each operation has been accepted. More specifically, as shown in FIG. 3, each push button 31A, 31B, 31C, ... Is a translucent part (light emitting part) L-1, L-2 in the shape of a number indicating the destination floor on the front side. , L-3, ... (Hereinafter, when it is not necessary to distinguish them, they are referred to as "transmissive part L"). Then, when a lamp (not shown) provided inside the push button 31 is turned on, the translucent portion L is configured to emit 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 portion 32L is configured to be capable of emitting light. In the present embodiment, unlike the door open button 32, the door close button 33 is not provided with the door open sensor unit corresponding to the button 33, but is provided with the door open sensor unit corresponding to the button 33. May be.

Then, by pressing the push button 31 or by detecting a shield such as a hand by the destination floor sensor unit 34, the (call) registration of the destination floor is performed and the translucent unit L is turned on. As a result, when the input operation is performed via each button 31, the user can visually confirm the acceptance status of each input operation. Similarly, when the door open button 32 is pressed or when the door open sensor unit 35 detects light shielding by a shield such as a hand, the light transmissive unit 32L lights up. In this embodiment, the push button 31 and the door open button 32 are used, but for example, a touch sensor or the like may be used.

Since the destination floor sensor unit 34 and the door open sensor unit 35 described above have substantially the same configuration, the configuration of the destination floor sensor unit 34 will be mainly described in the following description, and the door open sensor unit 35 will be appropriately described. The explanation is omitted.

Each destination floor sensor unit 34 is provided with substantially rectangular holes formed so that both ends are curved in the same direction, and each rectangular hole has a translucent protective plate 37A, as shown in FIG. They are covered with 37B, 37C, ... (Hereinafter, when it is not necessary to distinguish them, they are referred to as "protective plate 37"). A reflective photoelectric sensor in which a floodlight and a light receiver are integrated is housed in each rectangular hole of the sensor unit 34 on each destination floor, and the amount of reflected light received from an object received by the light receiver is irradiated with light from the floodlight. The presence or absence of an object is detected based on the change in.

Here, FIG. 4 is a cross-sectional view schematically showing the positional relationship between the destination floor sensor unit 34 and the detection area P. In FIG. 4, the detection area P is shown by hatching, and the configurations other than the destination floor sensor unit 34 and the detection area P are appropriately omitted. As shown in FIG. 4, the destination floor sensor unit 34 adjusts the amount of light received (sensor sensitivity) on the receiver side so that light blocking by an object (shield) in the preset detection area P can be detected. Will be done. Then, as shown in FIG. 4, this detection region P is a position separated by X2 in the same direction X from a position separated by a distance X1 in the horizontal direction X from the destination floor sensor unit 34 when 0 mm ≦ X1 <X2. It is set to be a spatial area including up to.

As shown in FIG. 3, the car operation panel 23 further has a display unit 44. The display unit 44 comprises, for example, a liquid crystal display, and displays, for example, the moving (elevating) direction of the car 22, the passing floor of the car 22, and other information to be notified to passengers. The display unit 44 is provided at a position that is easy for passengers to see above the operation unit 30. As shown by the broken line in FIG. 3, the car operation panel 23 has a built-in speaker (sound generator) SP that outputs sound. This speaker SP has a role of generating a sound for notifying passengers of a door opening operation or a door closing operation of the car doors 22A and 22B.

The car operation panel 23 having the above configuration is electrically connected to the 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 an input operation performed via the car operation panel 23 or the like, and includes a CPU, a memory, and the like. .. The memory includes, for example, drive control of the hoisting machine 16, opening / closing control of the car doors 22A and 22B, light-transmitting portion L of each push button 31, light-transmitting portion 32L of the door opening button 32, and lighting control of the guidance lighting LM. Various control programs are stored to control each speaker SP and the like. When the CPU reads these programs from the memory and executes them, the smooth operation of the elevator 10 by the control device 46 is realized.

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 related to registration of the destination floor of the car 22. In the control device 46, the CPU reads the control program from the memory and executes the door open mode and the door close mode. Here, the door opening mode is a mode for moving the car doors 22A and 22B in the door opening direction and holding the doors 22A and 22B in the door opening state. 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 in which the car doors are fully closed.

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

As shown in FIG. 5, when the door opening sensor unit 35 detects light shielding, the control device 46 determines whether or not the door can be opened (steps S1 and S2). The state in which the door can be opened includes a state in which the car 22 is landed on the landing 26 and it is not necessary to forcibly maintain the door closed state. As a result, even if the door open sensor unit 35 detects light blocking, the notification sound does not sound when the car 22 is not in the door openable state, and the light transmissive unit 32L of the door open button 32 and the guide are used. The lighting LM does not blink. Therefore, unnecessary guidance is not given to the passengers in the car 22.

In step S2, if it is determined that the door can be opened, the control device 46 executes the door open mode after a predetermined standby time elapses, except during the execution of the door close mode (steps S3, S4, S5). On the other hand, when the door closing mode is being executed, the control device 46 executes the door opening mode without waiting for the elapse of a predetermined waiting time (steps S3 and S5).

In step S5, the control device 46 generates a predetermined notification sound via the speaker SP when the door open mode is executed, and the translucent portion 32L (see FIG. 3) and the hanging wall 22-of the door open button 32. The guidance lighting LM (see FIG. 2) of No. 1 is blinked. The predetermined notification sound is, for example, an intermittent sound such as "pi-pi-pi ...". As a result, the detection status of the door open sensor unit 35 can be easily grasped even in a situation where the translucent unit 32L of the door open button 32 is difficult to see while the passenger is holding his / her hand over the door open sensor unit 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 in the door opening operation may be broadcast via the speaker SP. By generating a predetermined notification sound during the execution of the door opening mode as described above, the door is opened even when the door opening mode is executed, for example, when the passenger's luggage is detected by the door opening sensor unit 35. Passengers can quickly notice that the sensor unit 35 is detecting the luggage. Further, there is an advantage that the passenger can evacuate the luggage from the detection area of the door opening sensor unit 35 to promptly end the door opening mode and facilitate the operation of the elevator 10.

Next, as shown in FIG. 5, when the door opening sensor unit 35 stops detecting light blocking (step S6), the control device 46 first stops from the timing when it stops detecting light blocking (first non-detection timing). The door closing mode is executed after a predetermined time (for example, 3 seconds) has elapsed (steps S7 and S15).

With the above configuration, even if the door open sensor unit 35 does not detect light blocking due to the passenger inadvertently moving the hand held over the detection area of the door open sensor unit 35 out of the same area, the first predetermined time elapses. The door closing mode is started only later.

Here, when the door opening sensor unit 35 no longer detects light-shielding in step S6 described above, in other words, the control device 46 generates a notification sound or guidance lighting in step S5 at the timing when the light-shielding is no longer detected. It is preferable to stop the blinking of the LM. As a result, the passenger can immediately notice that the door opening sensor unit 35 has not detected light blocking.

Further, the control device 46 executes the door opening mode executed in step S5 described above after the first predetermined time elapses in step S7, in other words, until the door closing mode in step S15 is entered. .. As a result, the car doors 22A and 22B can be held in the open state until the first predetermined time elapses.

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

On the other hand, as shown in FIG. 5, when the door opening sensor unit 35 re-detects the light blocking effect before the elapse of the first predetermined time (step S8), the control device 46 has a predetermined standby time (for example, 0. After the elapse of (3 seconds) (step S9), the door open mode is executed (step S10).

In step S10, when the control device 46 executes the door open mode, the control device 46 generates a notification sound via the speaker SP as in the case of step S5, and also transmits the guidance illumination LM and the translucent portion 32L of the door open button 32. Make it blink. As a result, as in the case of step S5, the passenger can easily grasp the light-shielding detection state by the door opening sensor unit 35.

Then, as shown in FIG. 5, the control device 46 measures the time from the timing at which the detection is stopped (second non-detection timing) when the door open sensor unit 35 stops detecting the light blocking (step S11). Then, after the measured time (hereinafter referred to as "measurement time") elapses for the second predetermined time (for example, 3 seconds) (step S12), the door closing mode is executed (step S15).

Here, the control device 46 blinks the notification sound generated via the speaker SP in step S10 and the light transmitting portion 32L of the guidance lighting LM and the door open button 32, and the door open sensor unit 35 in step S11. Terminates when shading detection is stopped. Therefore, the passenger can easily grasp that the door opening sensor unit 35 has not detected light blocking. On the other hand, the control device 46 continues to execute the door open mode executed in step S10 until the second predetermined time elapses in step S12 and the transition to step S15 occurs. As a result, the car doors 22A and 22B can be held in the open state 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 hold his / her hand over the detection area of the door open sensor unit 35 before the door close mode is executed.

As shown in FIG. 5, when the door opening sensor unit 35 re-detects the light blocking effect before the second predetermined time elapses (step S13), the control device 46 resets the measurement time measured in step S12. That is, the measurement time is set to 0 seconds (step S14). As a result, even if the door open sensor unit 35 does not detect the light blocking after re-detecting the light blocking in step S13, the door is closed after waiting for the lapse of the second predetermined time (for example, 3 seconds) in step S12. The mode can be executed.

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 transmits the guidance illumination LM and the translucent portion 32L of the door open button 32. Make it blink.

Then, when the second predetermined time (for example, 3 seconds) elapses without the sensor unit 35 detecting the light blocking again from the timing when the control device 46 no longer detects the light blocking of the door opening sensor unit 35 (step S11, S12), the door closing mode is executed (step S15), and the opening / closing control processing of the series of car doors 22A and 22B is completed.

As described above, when the control device 46 changes from the detection state in which the door open sensor unit 35 detects light blocking to the non-detection state in which light blocking is not detected during the door opening mode, the control device 46 changes from the detection state. The door closing mode is executed after the first predetermined time has elapsed from the first non-detection timing that changes to the non-detection state. Further, if the door open sensor unit 35 re-detects the light blocking effect before the first predetermined time elapses, the second predetermined time elapses from the second non-detection timing in which the door opening sensor unit 35 does not detect the light shielding again after the re-detection. Later, the door closing mode is executed.

As a result, even if the passenger moves his / her hand out of the detection area of the sensor unit 35 while holding his / her hand over the door open sensor unit 35, the door close mode is not executed until a predetermined time has elapsed. .. Then, when the light-shielding is re-detected by holding a hand again before the predetermined time elapses, the door closing mode is not executed until the predetermined time elapses after the light-shielding is not detected again.

Therefore, when the passenger unintentionally moves the hand held over the door opening sensor unit 35 out of the detection area, the door is not detected at the timing when the sensor unit 45 does not detect light blocking. Even if the closed mode is not started and the above-mentioned non-detection occurs, the door open state can be maintained by holding a hand over the door open sensor unit 35 again. Therefore, it is not necessary to continuously hold the hand over the door open sensor unit 35 while holding the car doors 22A and 22B in the door open state, and the door open state can be maintained by occasionally holding the hand over the door open sensor unit 35. There is also an advantage.

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 the light-shielding detection by the door opening sensor unit 35. As a result, the passenger can easily grasp the detection status of the sensor unit 35 even when the passenger is holding his / her hand over the door opening sensor unit 35. In addition, when the passenger unintentionally causes the door opening sensor unit 35 to detect light blocking, the passenger can quickly notice that the sensor unit 35 is reacting (light blocking detection). ..

In steps S7 and S12 of the above embodiment, the control device 46 waits for the elapse of the first predetermined time and the second predetermined time, respectively, and emits a sound having a pattern different from the sound pattern generated in steps S5 and S10 from the speaker SP. It may be generated. As a result, there is an advantage that the door opening sensor unit 35 does not detect light shielding, and it is easy for passengers to know 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 via the speaker SP during the execution of the door open mode, and the guide lighting LM and the translucent portion 32L of the door open button 32. Although both are blinking, the above-mentioned intermittent sound may be generated and only one of them may be blinked. Further, the control device 46 may generate only intermittent sounds via the speaker SP and prevent the guidance illumination LM and the translucent unit 32L from blinking.

In the above embodiment, the first predetermined time and the second predetermined time are both set to 3 seconds, but the second predetermined time may be set longer than 3 seconds depending on the usage status of the elevator 10. However, it may be set shorter than 3 seconds. Further, both predetermined times may be set to different lengths.

The present invention can also be carried out in a mode in which various improvements, modifications, or modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Further, within the range in which the same action or effect is produced, any of the invention-specific matters may be replaced with another technique.
