Description

  Embodiments of the present invention relate to a passenger conveyor.

  The passenger conveyor includes a plurality of steps that are connected endlessly and circulates, and conveys passengers on the steps from one entrance to the other entrance. Conventional general passenger conveyors are operated at a constant speed of 30 m / min in principle. In recent years, for example, in passenger conveyors installed in station buildings, in order to increase passenger transportation capacity that increases during morning and evening commuting rush hours, the driving speed in the rush hour is increased from the normal driving speed, for example, Passenger conveyors operating at 40m / min can also be seen.

  The passenger conveyor having such a high operating speed can be said to be a preferable passenger conveyor for those who are busy, for example, because the transport capacity is increased and the congestion is eased and arrives at the target floor earlier. On the other hand, passenger conveyors with high driving speeds, for example, for young children and elderly people, may find it difficult to measure the timing of getting into the steps at the entrance and exit. There is a risk of hesitating to get on the steps from the board, or the body may become unbalanced and fall when getting on.

  In view of the fact that the above-mentioned young children and the elderly are not always out of balance and fall over even the passenger conveyor with a typical driving speed of 30 m / min, the young children and the elderly, etc. When using the passenger conveyor, it is desired to reduce the operation speed.

  Therefore, the passenger conveyor disclosed by patent document 1-patent document 3 is known as a passenger conveyor for preventing the accident where a young child or elderly person falls the balance of a body and falls.

  In Patent Document 1, an operation panel that can change the operation speed is installed in the vicinity of the entrance of the passenger conveyor, and the passenger operates the operation panel so that the operation speed is reduced to normal operation before getting into the passenger conveyor. A passenger conveyor that can smoothly and safely ride on a passenger conveyor by changing the speed slower than the speed is disclosed.

  In Patent Document 2, a passenger walking speed detection device that detects the walking speed of a passenger who is about to enter the passenger conveyor is provided near the entrance of the passenger conveyor, and the operation speed of the passenger conveyor is adjusted according to the detected walking speed. A passenger conveyor is disclosed in which a person who cannot smoothly get on and off the passenger conveyor, such as a young child or an elderly person, can get on and off the passenger conveyor smoothly and safely.

  Patent Document 3 includes first detection means for detecting on a boarding board provided at a boarding gate and second detection means for detecting the presence or absence of a passenger who has entered the step on a stage near the boarding board, Disclosed is a passenger conveyor that lowers the moving speed of a step from a normal speed when the first detection means detects a passenger for a predetermined time and the second detection means does not detect a passenger. Has been.

  However, in the invention disclosed in Patent Document 1, since the passenger himself / herself changes the driving speed through the operation panel, if a wrong operation is performed, the passenger conveyor breaks down or an unexpected accident occurs. May occur. In addition, it is necessary to install the operation panel that can be operated by passengers, operation panel installation poles, and the like in the vicinity of the entrance / exit of the passenger conveyor, and an increase in the installation cost of the passenger conveyor is inevitable.

  In the invention disclosed in Patent Document 2, even if the walking speed of the passenger is detected in advance and the driving speed of the passenger conveyor is adjusted in relation to the speed, the same walking speed as that detected when the passenger gets on the step. You don't always get in at speed. For example, when the passenger stops on the boarding board in order to measure the timing of getting on the steps of the passenger conveyor, a wrinkle occurs between the walking speed when getting on the steps and the walking speed detected in advance. Will get on the step at a speed slower than the walking speed detected in advance. Thus, the walking speed when getting into the step after all did not match the driving speed of the passenger conveyor, and there was a possibility that the passenger would fall out of balance and fall when the passenger got in. In addition, since the passenger walking speed detection device is installed at a position slightly away from the entrance / exit of the passenger conveyor, installation work must be performed separately from the passenger conveyor, which causes various problems such as cost and installation location. .

  In the invention disclosed in Patent Document 3, if it is a passenger conveyor that can be boarded side by side in the width direction, even if there is a user who crawls on the boarding board without entering the passenger conveyor on one side, There is a problem that when another user gets into the passenger conveyor without passing through the side of the user standing on the boarding board from the other side, the user standing on the boarding board cannot be detected.

  The present invention has been made in view of the above points, and even when another user gets on the side of a person who hesitates to get on the passenger conveyor, the passenger conveyor smoothly It is an object of the present invention to provide a passenger conveyor that detects passengers who cannot get on and off the vehicle and enables the passengers to safely get on the steps of the passenger conveyor.

  The passenger conveyor according to the embodiment includes a first detection means for detecting the presence / absence of a passenger getting on the step on a boarding / alighting board provided at the entrance / exit, and a second detection for detecting the presence / absence of a passenger getting on the step on the step. Means, a judging means for judging a passenger's situation on the board based on information from the first detecting means and the second detecting means, and a driving device based on a judgment result of the judging means A control device that changes a moving speed of the step that is driven, and the first detection means is a first detection means on one side that detects the presence or absence of a passenger entering the step through one side in the width direction. And a first detecting means for detecting the presence or absence of a passenger entering the step through the other side in the width direction, wherein the second detecting means detects the presence or absence of a passenger getting on the one side in the width direction of the step. One side second detection means and step A second detection means on the other side for detecting the presence or absence of a passenger who has entered the other side in the width direction, and the control device is one of the first detection means on the one side and the first detection means on the other side. Detects the passenger for a predetermined time, and the second detection means for detecting the presence or absence of the passenger who has entered the step on the same side as the first detection means for detecting the passenger for the predetermined time detects the passenger. If not, control is performed to make the moving speed of the step slower than the normal speed.

  In addition to the passenger conveyor control device 4 and the speed reduction device 6 described above, a power converter for changing the operation speed of the passenger conveyor 1, for example, an inverter device 20 is provided as a main circuit for rotating the electric motor 5. Moreover, it has the power regeneration unit 21 which regenerates the energy which generate | occur | produces when the passenger conveyor 1 descend | falls to a power supply. Furthermore, a noise filter 23 and a reactor 24 are provided on the power source 22 side for high frequency countermeasures.

  A first detection device 25 and a second detection device 26 are connected to the passenger conveyor control device 4. The first detection device 25 is for detecting the presence or absence of a passenger who is on the boarding / alighting plates 14 a and 14 b of the passenger conveyor 1 and intends to enter the step 11.

  The second detection device 26 is provided to detect the presence or absence of a passenger who has entered the step 11 from the boarding / alighting plates 14a and 14b.

  The detection signals sent from these detection devices 25 and 26 are input to the judgment means 4a provided in the passenger conveyor control device 4, and the situation of passengers on the boarding boards 14a and 14b by this judgment means 4a. Based on the determination result, a passenger conveyor operation speed signal is output to the inverter device 20 to which the passenger conveyor control device 4 is connected to change the operation speed. The passenger conveyor control device 4 also outputs a signal to the power regeneration unit 21 to control the regeneration operation of the power regeneration unit 21.

  Next, the determination device 4a in the passenger conveyor control device 4 determines the passenger status on the boarding board based on the information from the first detection device 25 and the second detection device 26, and based on the determination result, the passenger conveyor Specific contents of the control by which the control device 4 controls the electric motor 5 will be described with reference to FIGS.

  First, the 1st detection apparatus 25 and the 2nd detection apparatus 26 are demonstrated using FIG. 3, FIG. FIG. 3 is a plan view showing the vicinity of the entrance on the upper floor side of the passenger conveyor 1, and FIG. 4 is a front view of the passenger conveyor 1 shown in FIG. In addition, as shown by the arrow in FIG. 3, a passenger shall approach the passenger conveyor 1 toward the left side from the drawing right side. Further, in FIG. 4, in order to facilitate understanding, the exterior side of the passenger conveyor 1 and the depth side from the balustrade on the front side are shown, and the description of the step chain 10 connecting the plurality of steps 11 is omitted. .

  In FIG. 3, a comb portion 18 that scoops up a foot or the like by engaging with a groove on the upper surface of the step 11 is provided at a portion where the step 11 is extended. A boarding board 14a is provided on the floor in connection with the comb section 18. A passenger conveyor control device 4, an electric motor 5, and the like are housed in an upper floor side machine room provided at the lower part of the boarding / alighting plate 14a.

  In the present embodiment, the first detection device 25 is provided on the boarding / alighting plate 14 a in a region extending from the comb portion 18 to the vicinity of the tip end portion of the balustrade 15. In the first detection device 25, the detection range is divided into two in the width direction of the passenger conveyor 1, and the presence / absence of a passenger getting on the step 11 through one side (for example, the left side) from the width direction center of the boarding / alighting plate 14a is determined. One side first detection device 25L to detect, and the other side first detection device 25R to detect the presence or absence of passengers entering the step 11 through one side (for example, the right side) from the center in the width direction of the descending plate 14a. Yes.

  As the one side first detection device 25L and the other side first detection device 25R constituting the first detection device 25, one that detects the presence or absence of a passenger by displacement or pressure change due to the passenger's own weight can be used, for example, A mat switch or a piezoelectric sensor used for an automatic door or the like can be preferably used. Since these mat switches and piezoelectric sensors can be used simply by being placed on the boarding / alighting plate 14a, they are simple and do not cost much. Passengers who enter the step 11 through one side in the width direction of the boarding board 14a by separately providing detection devices on the one side and the other side in the width direction of the boarding board 14a at positions close to the step 11 meshing with the comb portion 18. And a passenger who enters the step 11 through the other side in the width direction of the boarding / alighting plate 14a can be detected separately.

  In this embodiment, a case where a mat switch or a piezoelectric sensor is used as the first detection device 25 will be described. However, as shown in FIGS. 6 and 7, reflection is performed near the inlet portion 31 of the left and right skirt guards 17. It may be a type of photoelectric sensor.

  A plurality of second detection devices 26 are arranged at equal intervals on the pair of skirt guards 17 provided at the lower portions of the left and right balustrades 15. As with the first detection device 25, the second detection device 26 has a detection range that is divided into two in the width direction of the passenger conveyor 1, and detects the presence or absence of a passenger who has entered the width direction one side of the step 11. The second detection device 26L and the other second detection device 26R that detects the presence or absence of a passenger who has entered the other side in the width direction of the step 11 are provided.

  As the one-side second detection device 26L and the other-side second detection device 26R constituting the second detection device 26, for example, a reflective photoelectric sensor including a light receiving element and a light projecting element can be suitably used. For example, by providing a reflective photoelectric sensor in each of the left and right skirt guards 17, a passenger who has entered one side in the width direction of the step 11 and a passenger who has entered the other side in the width direction of the step 11 are detected separately. be able to. In the present embodiment, four one-side second detection devices 26L1, 26L2, 26L3, and 26L4 are provided on the left and right skirt guards 17, and the other skirt guard 17 has four other second-side detection devices 26R1, 26R2, 26R3, and 26R4 are provided. By providing a plurality of second detection devices 26 on the left and right sides, it is possible to more reliably grasp not only the presence or absence of passengers but also a series of situations of passengers getting on the step 11 from the boarding board 14a. Further, in the case where a plurality of second detection devices are provided on the left and right skirt guards 17, the intervals between the second detection devices 26 are the same as the intervals between the front wheels and the front wheels of the adjacent steps 11, for example. By doing so, the presence or absence of a passenger on each step 11 can be determined.

  Next, control of the passenger conveyor 1 in the present embodiment will be described based on FIG. 5 showing a flow in which the control device 4 controls the electric motor 5.

  First, in step S1, a passenger conveyor operation speed signal is output from the passenger conveyor control device 4 to the inverter device 20 so as to operate at a normal constant speed (specified speed), for example, at a speed of 30 m / min. Based on this signal, the inverter device 20 supplies a frequency and a voltage corresponding to the signal to the electric motor 5, and the electric motor 5 drives the step 11 of the passenger conveyor 1 at a speed of 30 m / min.

  Next, in step S2, the determination device 4a determines whether the detection signal is sent from the first detection device 25L on the one side or the first detection device 25R on the other side in the width direction on the board 14a. It is determined whether the passenger is present on the side continuously for a predetermined time (for example, 3 seconds). If the determination device 4a determines that the passenger exists for a predetermined time (Yes in step S2), the process proceeds to step S3, and if the determination device 4a determines that the passenger does not exist for the predetermined time (NO in step S2). ), Returning to step S1, the passenger conveyor 1 is operated at a constant speed of 30 m / min.

  Next, in step S3, the determination device 4a determines the boarding / alighting plate 14a based on whether a detection signal is sent from the second detection device 26 on the same side as the first detection device 25 that detected the passenger in step S2. It is determined whether or not there is a passenger who passes through the step 11. If the determination device 4a determines that there is a passenger boarded on the step 11 (Yes in step S3), the process proceeds to step S4, and there is no passenger boarded on the step 11 or at least the first two steps near the boarding board 14a. When the determination device 4a determines that no passenger is present on the step 11 (NO in step S3), the process proceeds to step S7.

  In step S4, the passenger is present on the boarding board 14a, and the passenger is also present on the step 11 following the boarding board 14a, that is, the passenger is already on the stage 11 even if he / she tries to get on the stage 11. Since there are passengers, it is possible to determine that the board 11 is overflowing on the boarding board 14a without being able to grab and get on the step 11. In the present embodiment, four pairs of left and right second detection devices 26 are provided. When all of the second detection devices 26 detect the presence of passengers, they get on the boarding board 14a and the step 11 and enter the first 4 It can be judged that the situation is crowded with passengers on all stages.

Therefore, in step S4, the passenger conveyor control device 4 transmits an operation speed change signal for setting the operation speed of the passenger conveyor 1 to 40 m / min, for example, to the inverter device 20, and the moving speed of the step 11 is higher than the specified speed. Change to Thereby, passengers overflowing on the boarding / alighting board 14a can be quickly boarded on the passenger conveyor 1. And after changing the moving speed of the step 11 to high speed, in step S5, the one side first detection device 25L and the other side Based on whether or not a detection signal is sent from the first detection device 25R, it is determined whether or not there are passengers on one side and the other side in the width direction on the boarding / alighting plate 14a. When the determination device 4a determines that there is a passenger on at least one of the width direction one side and the other side on the boarding / alighting plate 14a, that is, there is a passenger on the boarding / alighting plate 14a (Yes in step S5), the process returns to step S4. The operation speed operated at 40 m / min is maintained as it is. Further, when the determination device 4a determines that there is no passenger on both the one side and the other side in the width direction on the boarding / alighting plate 14a, that is, no passengers exist on the boarding / alighting plate 14a (No in step S5), step S6. Then, the passenger conveyor control device 4 sends an operation speed change signal for returning the operation speed of the passenger conveyor 1 to 30 m / min to the inverter device 20, and changes the moving speed of the step 11 to a specified speed.

  On the other hand, in step S7, there are passengers on one side in the width direction on the boarding / alight board 14a and the other side, but there are no passengers on the step 11 on the same side, or at least on the boarding board 14a. A state in which no passengers are present on the first two steps 11 on the same side, that is, a passenger who is about to enter the step 11 is present on one side of the boarding / alighting plate 14a. It can be determined that the timing does not match and one side of the step 11 is vacant, but it is not possible to get on the step 11 following the boarding board 14a.

  Therefore, in step S7, the passenger conveyor control device 4 transmits an operation speed change signal for setting the operation speed of the passenger conveyor 1 to, for example, 20 m per minute to the inverter device 20, and the moving speed of the step 11 is lower than the specified speed. Change to Thereby, the passenger who overflowed on the boarding board 14a can be boarded on the passenger conveyor 1 rapidly. This makes it easier for passengers who are hesitant to get on the step 11 on the boarding / alighting board 14a to grasp the timing to get on. In addition, although it is assumed here that the driving speed is 20 m / min, the driving speed is not limited to the driving speed shown here as long as it is slower than the specified speed.

  And after changing the moving speed of the step 11 to low speed, in step S8, the determination apparatus 4a is a predetermined time (for example, from the 1st detection apparatus 25 on the same side as the 1st detection apparatus 25 which detected the passenger in step S2). Whether or not the detection signal is continuously sent for 3 seconds), that is, the passenger who was hesitant to get on the step 11 on the boarding / alighting plate 14a decreases the moving speed of the step 11 and then moves to the step 11 Determine if you have boarded. A detection signal is continuously sent from the first detection device 25 for a predetermined time, and even if the moving speed of the step is reduced, the passenger is still on the boarding board 12a and hesitates to get on the step 11. When the determination device 4a determines (Yes in step S8), the process proceeds to step S9, where the passenger conveyor control device 4 sends an operation speed change signal for setting the operation speed of the passenger conveyor 1 to the inverter device 20, for example, 10 m / min. Is transmitted, and the moving speed of the step 11 is changed to a lower speed. Further, when the detection device 4a determines that the detection signal is not transmitted continuously from the first detection device 25 for a predetermined time and the passenger who has been hesitant has boarded the step 11 (No in step S8), the process proceeds to step S10. The passenger conveyor control device 4 sends an operation speed change signal for returning the operation speed of the passenger conveyor 1 to 30 m / min to the inverter device 20 to change the moving speed of the step 11 to a specified speed. This makes it easier for passengers who are hesitant to get on the step 11 on the boarding / alighting board 14a to grasp the timing of getting on more easily.

  In the present embodiment, when there are passengers who cannot enter the passenger conveyor 1, the driving speed is decreased in two steps from the normal driving speed. However, the present invention is not limited to this mode. By adjusting, the driving speed can be freely changed.

  The passenger conveyor 1 according to the present embodiment as described above smoothly gets on and off the passenger conveyor even when another user gets on the side of the person who hesitates to get on the passenger conveyor. It is possible to detect a passenger who cannot do so, and to reduce the moving speed of the step 11, so that the passenger can safely board the step 11.

  In addition, in this embodiment, when changing the moving speed of the step 11, you may implement the broadcast which alerts the passenger who gets on the step 11 that the moving speed of the step 11 is changed with a sound. Thereby, since the passenger is notified in advance that the moving speed of the step 11 is changed, an accident associated with the speed change can be prevented in advance.

  As mentioned above, although embodiment of this invention was described, these embodiment was shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
