Abstract

A passenger conveyor is provided that enables smooth and safe boarding and alighting even in a passenger conveyor in which a conveying section may accelerate or decelerate. A notification unit provided near a boarding/alighting gate emits a notification sound such that at least one of the pitch, volume, and tone color of the sound changes according to the speed of the conveying unit. This allows the passenger to audibly grasp the speed of the transport unit. Therefore, even if the conveying section is a passenger conveyor that may accelerate or decelerate, the movement timing between the boarding/alighting port and the conveying section can be determined, and passengers can get on and off smoothly and safely.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor that conveys passengers by means of an endless conveying body that circulates.

Passenger conveyors, such as escalators and moving walkways, are provided with an entrance and exit and a transport section. The entrance/exit has a floor plate and is located at the beginning and end of the passage (entrance and exit). The conveying unit includes an endless conveying body composed of a plurality of steps that are endlessly connected and circulate, and the endless conveying body circulates along a passage to convey passengers. Passengers move from the entrance to the beginning of the transport section (passenger receiving section), get on the steps emerging from the tip of the floor plate, are transported by the transport section, and then reach the terminal end of the transport section (passenger delivery section). ), move to the exit, and continue to move to leave the passenger conveyor.

However, the boarding gate is stationary and the conveying section is moving, and a speed difference occurs between them. For this reason, there are some passengers who cannot make good timings of movement between the boarding/alighting gate and the transport section. Therefore, there has been proposed a passenger conveyor provided with an informing device for informing the movement timing (Patent Literatures 1 and 2). This is to generate a sound in synchronism with the movement of steps appearing from the front end of the floor plate or trying to enter under the floor plate at the doorway.

JP-A-58-125586 Japanese Patent Application Laid-Open No. 2-291390

By the way, in the passenger conveyor, the conveying section stops or operates at low speed while passengers are waiting, and when a passenger enters the boarding gate, the conveying section accelerates to the rated speed and enters rated operation. There are passenger conveyors with self-driving features that, when run out, the transport section decelerates and stops again or runs at low speed.

In a passenger conveyor with an automatic operation function, when the conveying unit accelerates, the speed of the steps gradually increases, and conversely, when the conveying unit decelerates, the speed of the steps gradually decreases. For this reason, when the notification devices of Patent Documents 1 and 2 are applied to a passenger conveyor with an automatic operation function, the intervals between sounds are not always constant and may change. And when the interval between sounds changes, it becomes difficult for passengers to get the timing right. In particular, when carrying a child or carrying a large carrying case, the downward visibility is blocked, and for visually impaired people, it is impossible to visually grasp the speed of the transport section. becomes more difficult.

<Overall composition>
Hereinafter, each embodiment of an escalator, which is one of the passenger conveyors, will be described as an embodiment of the present invention. Prior to this, the overall structure of the escalator will be described.

As shown in FIGS. 1 and 2 , the escalator 1 includes a truss 2 , an entrance/exit 3 , a transport section 4 , a handrail section 5 and a control section 6 . The truss 2 is a structure that supports the weight of the escalator 1 and its load. The entrance/exit 3 is provided above both ends of the truss 2 and positioned at the ends (starting end and terminal end) of the passage. The conveying part 4 is supported by the truss 2, and the tread moves along the path, thereby conveying the passenger while standing at that position without making the passenger walk. Handrail sections 5 are also supported by the trusses 2 and are provided along the passage on either side of the passage. The control unit 6 controls each part of the escalator 1 and controls smooth operation of the escalator 1 . The control unit 6 is provided in the form of a control panel.

In the present embodiment, the escalator 1 is set up to transport passengers from left to right (from downstairs to upstairs). For this reason, the escalator 1 has, from left to right, an entrance 3A, a transport section 4, and an exit 3B. When the setting is reversed by the control unit 6, the boarding gate 3A is switched to the boarding gate and the boarding gate 3B is switched to the boarding gate, and the passengers are transported from right to left (upstairs to downstairs).

The entrance/exit 3 is provided above the horizontal end 2 a of the truss 2 . The entrance/exit 3 has a floor plate 30 . The floor plate 30 constitutes the floor of the entrance/exit 3 and is installed at the ends (starting end and terminal end) of the passage. A comb-like comb 31 is attached to the tip of the floor plate 30 . The comb 31 is divided into a plurality of parts in the horizontal direction, each of which has a rectangular shape (rectangular shape). The plurality of combs 31, . The tip of the floor plate 30 (the tip of the comb 31 ) defines the boundary between the entrance/exit 3 and the transport section 4 .

The transport section 4 includes an endless transport body 40 . The endless conveying body 40 is formed by connecting a plurality of steps (steps) 41, . . . The endless carrier 40 is arranged in the truss 2 along the longitudinal direction of the truss 2 so as to be cyclically movable. The drive mechanism of the transport unit 4 includes a drive motor 42 , a reduction gear 43 , a pair of sprockets 44 and 44 and a step chain 45 . The drive motor 42 and the speed reducer 43 are provided at the horizontal end portion 2a on the upper end side of the truss 2 . One sprocket 44 is also provided at the horizontal end 2a on the upper end side of the truss 2, and the drive of the drive motor 42 is transmitted via a reduction gear 43 and a transmission means such as a chain or belt. The other sprocket 44 is provided at the horizontal end 2a on the lower end side of the truss 2 . The step chain 45 is means for endlessly connecting the plurality of steps 41, . . . The endless conveying body 40 circulates in one direction or the opposite direction as the step chain 45 circulates as the drive motor 42 is driven. Of the two folded ends of the step chain 45, the folding means for the driven side folded end (the left side in FIG. 1) may be a semicircular guide rail instead of the sprocket 44.

The handrail section 5 includes a handrail 50 and a balustrade 51 . The handrail 50 is also called a moving handrail and is flexible and endless. The handrail 50 circulates in conjunction with the endless carrier 40 . The balustrade 51 is arranged along the longitudinal direction of the endless carrier 40 on the side of the endless carrier 40 . The balustrade 51 has a lower side supported by the truss 2 and supports the handrail 50 so as to be circulating. A pair of handrails 50 and balustrades 51 are provided along the aisle on either side of the aisle.

As shown in FIG. 2 , the entrance/exit 3 includes a human detector 32 . The human detection unit 32 detects passengers entering the boarding gate 3A and detecting passengers exiting through the exit 3B. The human detection unit 32 is arranged at the end of the balustrade 51 . Alternatively, the human detection unit 32 is arranged on a pole (not shown) erected at the entrance/exit 3 . As an example, the human detection unit 32 is a human detection sensor such as an area sensor or a line sensor. The human detection unit 32 is electrically connected to the control unit 6 via power lines or signal lines.

When the escalator 1 is in a state in which no passenger is detected by the human detection unit 32 at the entrance 3A (a state in which there is no passenger), that is, when a passenger is waiting, the transport unit 4 stops or operates at a low speed, and the human detection unit 32 at the entrance 3A is detected. When the passenger is detected by the unit 32 (when the passenger enters the entrance 3A), the transport unit 4 accelerates to the rated speed (for example, 30 m/min) and enters the rated operation. This is a so-called automatic escalator in which the conveying unit 4 decelerates and stops again or operates at a low speed when a state in which no passenger is detected by the unit 32 continues for a certain period of time (when the passenger disappears). In the present embodiment, inverter control of the drive motor 42 is adopted as the operation control of the escalator 1 (speed control of the conveying unit 4). Values relating to the acceleration of the conveying unit 4 (for example, the acceleration of the conveying unit 4 itself, the rate of change in the rotational speed of the drive motor 42, etc.) are set in the control unit 6 in advance, and the control unit 6 is controlled based on these set values. Acceleration/deceleration control is performed.

The escalator 1 is equipped with a notification device. The notification device is a device that provides support for determining the movement timing between the boarding/alighting gate 3 and the transport section 4 to passengers who are about to get on and off. The notification device includes a notification unit 70 and a notification control unit.

The notification unit 70 is provided near the entrance/exit 3 . The notification unit 70 is arranged in the skirt guard 53 among the structures facing the passage of the balustrade 51 (the balustrade panel 52, the skirt guard 53, the deck cover 54, and the handrail guide 55). Alternatively, the notification unit 70 may be arranged on the balustrade panel 52 , the deck cover 54 or the handrail guide 55 . Alternatively, the notification unit 70 may be arranged on a pole (not shown) erected at the entrance/exit 3 . As an example, the notification unit 70 is an audio device such as a speaker. The notification unit 70 is electrically connected to the notification control unit via a power line or a signal line. Thereby, the notification unit 70 is controlled by the notification control unit.

The function of the notification control unit is executed by the control unit 6 of the escalator 1 . The notification control section includes a storage section, a calculation section, a signal generation section, and a command section (transmission section).

The storage unit stores a “correspondence relationship between the speed of the conveying unit 4 and the notifying sound” defined so that the notifying sound changes according to the speed of the conveying unit 4 . As an example, the correspondence between the speed of the conveying unit 4 and the notification sound is stored in the form of a table.

The calculation unit performs processing (speed calculation processing) for calculating the speed of the conveying unit 4 (the speed of the endless conveying body 40) at predetermined time intervals (for example, 200 msec intervals). The speed of the transport unit 4 can be calculated based on the rotation speed of the drive motor 42 of the transport unit 4 . In addition, the calculation unit determines the timing of the movement of the step 41, more specifically, the step 41 (the tip thereof) emerges from the tip of the floor plate 30 or tries to enter under the floor plate 30 at the same time interval as the speed calculation process. Processing for calculating timing (timing calculation processing) is performed. The timing is calculated based on the calculated speed of the conveying unit 4, the fact that the control unit 6 grasps the origin position of the endless conveying body 40, and the depth dimension of the steps 41 (generally about 40 cm). can do.

The signal generation unit identifies the corresponding notification sound from the correspondence relationship between the speed of the transport unit 4 and the notification sound, and performs processing (signal generation processing) to generate a signal related to the notification sound. The command unit transmits a signal related to the notification sound to the notification unit 70 and performs processing (notification command processing) to cause the notification unit 70 to generate the notification sound.

The correspondence relationship between the speed of the conveying unit 4 and the notification sound is as one pattern, as shown in FIG. It is defined to change. The speed of the conveying unit 4 is, for example, 0<V≦V1 (for example, 10 m/min), V1<V≦V2 (for example, 20 m/min), and V2<V≦Vr (rated speed, for example, 30 m/min). A notification sound with a frequency f1 is assigned to the first speed segment, and a notification sound with a frequency f2 higher than that of the first speed segment is assigned to the second speed segment. is assigned to the third speed segment, and the notification sound of frequency f3, which is higher in sound than the notification sound of the second speed segment, is assigned to the third speed segment. Note that the number of speed segments may be two, or four or more (the same shall apply hereinafter).

Regarding the correspondence relationship between the speed of the conveying unit 4 and the notification sound, as another pattern, as shown in FIG. It is defined to change. A notification sound with an amplitude A1 is assigned to the first speed segment, a notification sound with an amplitude A2 that is louder than the notification sound of the first speed segment is assigned to the second speed segment, and a third speed segment is assigned a notification sound. The speed segment is assigned an alerting sound of amplitude A3, which is louder than the alerting sound of the second speed segment.

As for the correspondence relationship between the speed of the conveying unit 4 and the notification sound, as shown in FIG. It is defined to change. The first speed segment is assigned a notification sound with a timbre t1 of only the fundamental tone, the second speed segment is assigned a notification sound with a timbre t2 in which the fundamental tone is synthesized with one overtone, and the third is assigned to the notification sound of the timbre t3, which has a larger number of synthesized overtones than the notification sound of the second speed segment.

<Notification form 1 of notification device>
Timing charts of notification mode 1 of the notification device are shown in FIGS. 6(a) and 6(b). Note that FIG. 6(a) is an example of an automatic escalator that is applied to a type of escalator in which the conveying unit 4 is stopped while passengers are waiting, and FIG. is an example applied to an escalator in which the conveying unit 4 operates at a low speed.

In the example of FIG. 6(a), when a passenger enters the boarding gate 3A from the passenger waiting state (when the passenger who has entered the boarding gate 3A is detected by the human detection unit 32), the vehicle is stopped until then. Then, the conveying unit 4 is accelerated to the rated speed Vr and enters the rated operation. In the example of FIG. 6B, when a passenger enters the boarding gate 3A while waiting for passengers, the transport unit 4, which has been operating at a low speed at the speed V1 up to that point, accelerates to the rated speed Vr and resumes rated operation. Become. Note that the acceleration time (and deceleration time) is several seconds (3 to 5 seconds).

In the notification mode 1 of the notification device, the notification control unit continuously performs a series of processes of speed calculation processing, signal generation processing, and notification command processing at the predetermined time intervals (minute time intervals) during the operation of the conveying unit 4. . One of patterns 1 to 7 below is selected as the pattern of the notification sound. The notification control unit generates a signal related to the notification sound based on the selected pattern, and issues a notification command to the notification unit 70 . As a result, for example, in the case of pattern 1, the notification sound is emitted from the notification unit 70 so that the sound increases step by step as the speed of the conveying unit 4 increases. In pattern 2, the notification sound is emitted from the notification unit 70 such that the sound increases step by step as the speed of the transport unit 4 increases.

As described above, according to the notification mode 1 of the notification device, at least one of the pitch, volume, and tone of the sound changes according to the speed of the conveying unit 4 from the notification unit 70 provided near the entrance 3A. A notification sound is emitted. A change in the notification sound is a change in the sound that conceptually recognizes the slowness of the speed of the conveying unit 4 . This allows the passenger to audibly grasp the speed of the transport unit 4 . For this reason, according to the notification mode 1 of the notification device, even in the case of an automatic escalator in which the transport unit 4 may accelerate or decelerate, the movement timing between the entrance/exit 3 and the transport unit 4 can be determined, and the movement can be performed smoothly and efficiently. You can get on and off safely.

<Notification form 2 of notification device>
The timing charts of notification mode 2 of the notification device are shown in FIGS. 7(a) and 7(b). Note that FIG. 7(a) is an example of an automatic escalator applied to a type of escalator in which the conveying unit 4 is stopped while passengers are waiting, and FIG. is an example applied to an escalator in which the conveying unit 4 operates at a low speed.

In the notification mode 2 of the notification device, the notification control unit (signal generation unit thereof) performs predetermined notification in accordance with the timing calculated by the timing calculation processing in addition to the signal generation processing (first signal generation processing). A process of generating a signal related to sound (second signal generation process) is performed. In addition to the notification command processing (first notification command processing), the notification control unit (the command unit thereof) notifies a signal related to the predetermined notification sound in accordance with the timing calculated by the timing calculation processing. A process (second notification command process) for transmitting the information to the notification unit 70 and generating the predetermined notification sound from the notification unit 70 is performed.

That is, in the notification mode 2 of the notification device, the notification control unit performs a series of processes including the speed calculation process, the timing calculation process, the first signal generation process, and the first notification command process at predetermined time intervals (minute time intervals). ) is continuously performed during operation of the conveying unit 4, and the second signal generating process and the second notification command process are performed intermittently at intervals synchronized with the movement of the step 41. The selectivity of the pattern of the notification sound (first notification sound) is the same as in the notification mode 1 of the notification device. Also, as the pattern of the predetermined notification sound (second notification sound), one of the following patterns A to D is selected. The notification control unit generates signals for the first and second notification sounds based on the selected pattern, and issues a notification command to the notification unit 70 .

As described above, according to the notification mode 2 of the notification device, at least one of the pitch, volume, and tone of the sound changes according to the speed of the conveying unit 4 from the notification unit 70 provided near the entrance 3A. A notification sound (first notification sound) is emitted at the time of the step 41, and a notification sound (second notification sound) is emitted at intervals synchronized with the movement of the steps 41. As shown in FIG. This allows the passenger to audibly grasp the speed of the transport section 4 . Therefore, according to the notification mode 2 of the notification device, even if the conveying unit 4 is an automatic escalator that may accelerate or decelerate, the movement timing between the entrance/exit 3 and the conveying unit 4 can be determined, and the movement can be performed smoothly and efficiently. You can get on and off safely.

<Notification form 3 of notification device>
The timing charts of notification form 3 of the notification device are shown in FIGS. 8(a) and 8(b). Note that FIG. 8(a) is an example of an automatic escalator that is applied to an escalator of a type in which the conveying unit 4 is stopped while passengers are waiting, and FIG. is an example applied to an escalator in which the conveying unit 4 operates at a low speed.

In the notification mode 3 of the notification device, the notification control unit continuously performs a series of processes of the speed calculation process and the timing calculation process at the predetermined time intervals (minute time intervals) during the operation of the transport unit 4, and generates a signal. Processing and notification command processing are performed intermittently at intervals synchronized with the movement of the steps 41 . The selectivity of the notification sound pattern is the same as in the notification mode 1 of the notification device. The notification control unit generates a signal related to the notification sound based on the selected pattern, and issues a notification command to the notification unit 70 .

As described above, according to the notification mode 3 of the notification device, the notification unit 70 provided near the entrance 3A changes at least one of the pitch, volume, and timbre of the sound according to the speed of the conveying unit 4. , and at intervals synchronized with the movement of the step 41, an alarm sound is emitted. This allows the passenger to audibly grasp the speed of the transport unit 4 . Therefore, according to the notification mode 3 of the notification device, even if the transport unit 4 is an automatic escalator that may accelerate or decelerate, the movement timing between the entrance/exit 3 and the transport unit 4 can be determined, and the movement can be performed smoothly and efficiently. You can get on and off safely.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

In the above-described embodiment, the speed of the conveying unit 4 is divided into a plurality of speed divisions, and the content of the sound differs for each speed division, so that the notification sound changes stepwise. However, the invention is not limited to this. As shown in FIG. 9, the notification sound may linearly change according to the speed of the transport section.

Further, in the above embodiment, the speed of the conveying section 4 is calculated based on the rotation speed of the drive motor 42 . However, the invention is not limited to this.

However, the invention is not limited to this. For example, since the rotation speed of the drive motor 42 of the transport unit 4 and the speed of the transport unit 4 are in a proportional relationship, the notification control unit is defined so that the notification sound changes according to the speed of the transport unit 4. As the correspondence relationship, the "correspondence relationship between the rotation speed of the drive motor 42 and the notification sound" may be used, and as the information regarding the speed of the conveying unit 4, the rotation speed information of the drive motor 42 may be used. Alternatively, since the frequency input to the drive motor 42 and the speed of the conveying unit 4 are in a proportional relationship in inverter control, the notification control unit is defined so that the notification sound changes according to the speed of the conveying unit 4. As the correspondence relationship, "the correspondence relationship between the frequency input to the driving motor 42 and the notification sound in the inverter control" may be used, and the frequency information input to the driving motor 42 may be used as the information regarding the speed of the conveying unit 4. good.

Further, in the above-described embodiment, the notification form at the boarding gate 3A has been mainly described. However, as described above, it goes without saying that the invention can also be applied to exits.
