Description

Technical Field

[0001] The present invention relates to the technology of transfer machines.

Background Art

[0002] Problems when wheelchair users use railways have been pointed out. For example, the "Investigation Report on Improving the Wheelchair-using Environment in Railways" (Ministry of Land, Infrastructure, Transport and Tourism, March 2018) points out that there are gaps and steps between platforms and vehicles in many railways operating in Japan, and in many cases, it is necessary for station staff etc. to assist with a boarding bridge (ramp) when wheelchair users board and alight from the railway. However, since many railway operators basically provide boarding guidance after contacting and arranging for a station and confirming the assistance system for transfer stations and alighting stations, it has been a problem that it takes time until the arrangements are completed. Therefore, the development of a transfer machine that does not require special procedures for wheelchair users when boarding and alighting from the railway is desired.

[0003] Patent Document 1 discloses a movable step device including a step portion that falls on the gap from the end of the platform to the vehicle in the first position and is separated from the track side in the second position, a drive portion that pivotally supports the step portion and rotates the step portion between the first position and the second position, and is attached to a part of the platform fence, and an attachment portion that attaches the drive portion to a part of the platform fence.

[0004] Patent Document 2 discloses a fall prevention device including a step portion for covering a gap from the boarding and alighting opening to the platform side end when boarding and alighting a vehicle during which the incoming line is stopped, two provided on the left and right of the step portion toward the boarding and alighting opening, a rotating shaft that rotates with the side portion on the movable platform fence side as the rotation center side, a drive portion that displaces the step portion to an upright posture or a horizontal posture by rotating this rotating shaft, and a drive control portion that drives and controls the drive portion so that the step portion is in an upright posture during non-boarding and alighting and in a horizontal posture during boarding and alighting. The step portion is configured such that it fits into a cutting portion obtained by cutting a platform floor portion between the movable platform fence and the platform side end by a predetermined thickness in the horizontal posture, and the upper surface is substantially flush with the upper surface of the platform.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In both of the technologies described in Patent Documents 1 and 2, like in a bounce bridge, during boarding and alighting, the step portion (also referred to as a boarding bridge or slope) is in a horizontal posture covering the gap between the platform and the boarding and alighting opening, and during non-boarding and alighting, the step portion is in an upward posture. This configuration requires less renovation work such as excavation and chopping on the existing platform compared to a configuration where the step portion is in a downward posture during non-boarding and alighting.

[0007] However, in the technologies of Patent Documents 1 and 2, if a failure occurs in the drive device in the upward posture state, the step portion may become a wall blocking the passage during boarding and alighting, hindering the passage of passengers. Also, if a failure occurs in the drive device in the horizontal posture state, the step portion may collide with the train running.

[0008] An object of the present invention is to attach an extension plate to the tip of a plate-like member to cover the gap to the entrance and exit of a train at the time of stopping and prevent passengers from falling, and to be able to remove this extension plate in case of failure or the like.

Means for Solving the Problems

[0009] The present invention rotates a plate-like member supported at the base on a shaft along the platform and provided with a detachable extension plate at the tip, and at the time of train stop, the tip is directed toward the entrance and exit of the train. A transfer machine having a first posture and a second posture in which the tip is directed upward of the shaft during train travel, wherein the extension The plate is made of Guide pin and the connecting member and The plate-like member has a guide hole and a guide hole is formed in the li the having, the extension plate is restricted from moving in a direction other than the extension direction from the base to the tip when the guide pin is inserted into the guide hole, and the connecting member is inserted into the hole, and a transfer machine in which movement in the extension direction is restricted, is provided as a first aspect.

[0010] According to the transfer machine of the first aspect, by attaching an extension plate to the tip of the plate-like member, the gap to the entrance and exit of the train at the time of stopping is covered to prevent passengers from falling, and this extension plate can be removed in case of failure or the like.

[0011] In the transfer machine of the first aspect, a configuration having a lock mechanism for fixing the plate-like member in the second posture, and the lock mechanism being releasable from the train side may be adopted as a second aspect.

[0012] According to the transfer machine of the second aspect, at the time of failure or the like, an operator such as a station staff, a crew member, or a passenger can release the lock mechanism from the train side and direct the tip of the plate-like member toward the entrance and exit of the train.

[0013] In the transfer machine according to the second aspect, when the plate-shaped member is fixed in the first posture, a configuration in which a platform fence provided at a position corresponding to the boarding and alighting opening is opened at the platform may be adopted as a third aspect.

[0014] According to the transfer machine of the third aspect, the platform fence opens when the tip of the plate-shaped member is directed toward the boarding and alighting opening of the train.

[0015] In the transfer machine according to the second or third aspect, a configuration in which the locking mechanism permits the train to run while the plate-shaped member is fixed may be adopted as a fourth aspect.

[0016] According to the transfer machine of the fourth aspect, the train is permitted to run when the tip of the plate-shaped member is directed above the shaft.

[0017] In the transfer machine according to any one of the first to fourth aspects, when there are no passengers on the plate-shaped member fixed in the first posture for a determined time, a configuration in which a platform fence provided at a position corresponding to the boarding and alighting opening is closed at the platform may be adopted as a fifth aspect.

[0018] According to the transfer machine of the fifth aspect, the platform fence closes when there are no passengers passing through the plate-shaped member for a determined time.

Mode for Carrying Out the Invention

[0020] <Embodiment> <Overall Configuration of the Management System> FIG. 1 is a diagram showing an example of the overall configuration of a management system 9 according to an embodiment of the present invention. The management system 9 manages the operation of the train 3, controls the operation of the station platform gate 2, and controls the operation of a transfer machine 1 that assists the transfer of passengers using a wheelchair or the like by facing the tip of a plate-like member provided with an extension plate at the boarding and alighting openings of the train when the train stops.

[0021] The management system 9 shown in FIG. 1 includes a transfer machine 1, a platform gate 2, a train 3, an operation panel C0, a transfer machine control device C1, a platform gate control device C2, an operation management device C3, an output device D, a passenger sensor E1, a platform gate sensor E2, and a train sensor E3.

[0022] The boarding mechanism control device C1 is a control device that controls the boarding machine 1, and is, for example, a computer having a processor, a memory, and an interface. The processor constituting the boarding mechanism control device C1 may be, for example, a CPU (Central Processing Unit), or may be a programmable logic device such as an FPGA (field-programmable gate array) or an ASIC (application specific integrated circuit).

[0023] Also, the boarding mechanism control device C1 may be a programmable logic controller. The boarding mechanism control device C1 may be a programmable logic controller (FS-PLC: Functional Safety programmable logic controller) that has obtained a third-party safety certification based on international standards such as IEC61508 defined by the International Electrotechnical Commission (IEC).

[0024] The interface of the boarding mechanism control device C1 is connected to the home gate control device C2 and the operation management device C3, and receives information about the home gate 2 and the train 3 from these. Also, the interface of the boarding mechanism control device C1 is connected to the operation panel C0, the output device D, and the passenger sensor E1. The boarding mechanism control device C1 exchanges signals with the operation panel C0 and the passenger sensor E1. Also, the boarding mechanism control device C1 controls the output device D.

[0025] The operation panel C0 is a panel operated by operators such as station staff, train crew, and passengers, and has operation elements such as buttons and levers for receiving the operations of the operators. When the operation panel C0 is operated in a determined procedure, a control signal corresponding to the operation is transmitted to the boarding mechanism control device C1, and the boarding machine 1 is controlled based on this control signal.

[0026] The output device D is a device that outputs notifications or presentations to passengers, station staff, train crew, etc. under the control of the transfer machine control device C1, and has, for example, a liquid crystal display, a speaker, etc. For example, the output device D having a speaker outputs a prerecorded voice, a synthesized voice, etc. to notify passengers, etc. of warnings and information.

[0027] The passenger sensor E1 is a sensor that senses the presence or absence of passengers in the vicinity of the transfer machine 1. The passenger sensor E1 may be, for example, an infrared sensor or a weight sensor such as a load cell. When the transfer machine control device C1 receives a signal from the passenger sensor E1 indicating that the presence of a passenger has been sensed, it refers to the operating state of the train 3 and the open / closed state of the platform gate 2, and controls the transfer machine 1 or the output device D.

[0028] For example, when the passenger sensor E1 senses the presence of a passenger while the train 3 is stopped and the boarding and alighting doors are open and the platform gate 2 is open, the transfer machine control device C1 extends the transfer machine 1 toward the boarding and alighting door so that the passenger can pass over the transfer machine 1, and causes the output device D to output a voice guiding boarding at the boarding and alighting door.

[0029] Also, for example, when the train is in motion or the platform gate 2 is closed and passengers cannot safely pass over the transfer machine 1, the transfer machine control device C1 turns the transfer machine 1 upward so that passengers cannot pass over the transfer machine 1, and causes the output device D to output a voice warning not to approach the transfer machine 1.

[0030] The platform gate control device C2 is a control device that controls the platform gate 2, and is, for example, a computer. The platform gate sensor E2 is a sensor that senses the position of the platform gate body in the platform gate 2, and is, for example, a contact output type sensor or a non-contact sensor. The platform gate control device C2 is connected to the platform gate sensor E2 and acquires the sensing result of the position of the platform gate body in the platform gate 2 from the platform gate sensor E2. Then, the platform gate control device C2 controls the platform gate 2 according to the sensing result acquired from the platform gate sensor E2.

[0031] The operation management device C3 is a management device that manages the operation of train 3 and is, for example, a computer. The train sensor E3 is a sensor that senses the position, speed, acceleration, opening / closing state of the boarding / alighting doors, etc. of train 3. The operation management device C3 is connected to the train sensor E3 and acquires the sensing results regarding the train from the train sensor E3. Then, the operation management device C3 controls train 3 according to the sensing results acquired from the train sensor E3.

[0032] <Usage status of the transfer device 1> Figure 2 is a diagram showing the usage status of the transfer device 1. In the figure, the space where each component is arranged is represented as an xyz right-handed coordinate space. The direction along the x-axis in the space is called the x-axis direction. Also, among the x-axis directions, the direction in which the x component increases is called the +x direction, and the direction in which the x component decreases is called the -x direction. For the y and z components, the y-axis direction, +y direction, -y direction, z-axis direction, +z direction, and -z direction are defined according to the above definitions.

[0033] In Figure 2, the -z direction is the direction in which gravity acts, that is, downward, and the +z direction is upward. Also, the y-axis direction is the direction in which the track on which train 3 travels extends. The +x direction is the direction in which a passenger moves when boarding train 3 from the platform H, and the -x direction is the direction in which a passenger moves when getting off train 3 to the platform H.

[0034] The transfer device 1 is installed at the position on the track side of the platform H of the station where the boarding / alighting door of train 3 stops. The platform gate 2 shown in Figure 2 is provided at the position where the boarding / alighting door of train 3 stops and can be in a state of blocking the boarding / alighting door (that is, the state of closing the platform gate body) and a state of opening the boarding / alighting door (that is, the state of opening the platform gate body). The platform gate body of the platform gate 2 may be, for example, a sliding door that opens along the traveling direction (y-axis direction) of the train, or one or more rod-shaped blocking members (lifting bars) that move along the vertical direction (z-axis direction).

[0035] The passenger is, for example, a user of the wheelchair V. The passenger rides on the wheelchair V and moves in the +x direction, passes over the transfer device 1 that is bridged to the boarding and alighting opening of the train 3, and boards the train 3. As shown in FIG. 2, on the platform H, a slope S may be provided to eliminate the displacement in the z-axis direction of the boarding and alighting opening, that is, the step, according to the position where the boarding and alighting opening of the train 3 stops. The inclination angle of the slope is desirably about 5 degrees (±1 degree), for example. The platform H may be raised so that the step with the boarding and alighting opening is less than 30 millimeters.

[0036] <Configuration of the transfer device 1> FIG. 3 is a diagram showing the configuration of the transfer device 1. The transfer device 1 includes a housing 10, a plate-like member 11, an extension plate 12, a drive unit 13, and a fixing unit 14. The housing 10 is a box-shaped member that is disposed on the platform H (see FIG. 2) and fixes the transfer device 1 to the platform H, and houses a shaft 100 (see FIG. 5) that supports the base of the plate-like member 11.

[0037] The extension plate 12 is detachably provided at the tip of the plate-like member 11. The drive unit 13 rotationally drives the shaft 100 (see FIG. 5) to swing (rotate) the plate-like member 11 supported by the shaft 100. The fixing unit 14 includes a locking mechanism that restricts the rotation of the shaft 100 and fixes the posture of the plate-like member 11.

[0038] FIG. 4 is a diagram for explaining the modified portion of the platform H. Among the coordinate symbols shown in the figure, the symbol with a dot drawn in the circle represents an arrow from the back side to the front side of the paper surface, and the symbol with two intersecting lines drawn in the circle represents an arrow from the front side to the back side of the paper surface. FIG. 4 shows a schematic view of the platform H seen in the +y direction. In order to fix the transfer device 1 shown in FIG. 2, the platform H needs to be excavated at the modified portion Hc shown in FIG. 4. This modified portion Hc is an end portion on the track side (+x direction) of the platform H and is a part of the upper surface. Therefore, this renovation work only requires a relatively small-scale work such as removing the coping stones or peeling off the tiles of the platform H.

[0039] FIG. 5 is a view showing the transfer machine 1 fixed to the platform H. The modified portion Hc shown in FIG. 4 has been excavated and removed in FIG. 5, and the housing 10 of the transfer machine 1 is disposed in the space where the modified portion Hc was located. The housing 10 is fixed to the platform H by one or more anchors 109 penetrating the platform H. The base portion 11b of the plate-like member 11 is rotatably supported by a shaft 100 extending along the y-axis direction. This shaft 100 is housed in the housing 10. The plate-like member 11 swings about this shaft 100.

[0040] An extension plate 12 is attached to the tip portion 11e of the plate-like member 11. When the train 3 is stopped, the transfer machine control device C1 controls the drive unit 13 (see FIG. 3) to rotationally drive the shaft 100 and set the plate-like member 11 in the posture shown in FIG. 5. As viewed from the shaft 100 shown in FIG. 5, the entrance / exit of the train 3 at the time of stopping is in the +x direction. Therefore, the posture of the plate-like member 11 shown in FIG. 5 is a posture (referred to as the first posture) in which the tip portion 11e is directed toward the entrance / exit of the train 3 at the time of stopping.

[0041] A pedal 101 is provided on the upper surface of the end portion on the track side of the platform H outside the housing 10. This pedal 101 is used to release the lock mechanism of the fixing portion 14 (see FIG. 3) that fixes the posture of the plate-like member 11.

[0042] FIG. 6 is a view showing the plate-like member 11 with the tip portion 11e directed upward of the shaft 100. When the train 3 is running, the transfer machine control device C1 controls the drive unit 13 (see FIG. 3) to rotate the plate-like member 11 about the shaft 100 so that the tip portion 11e is positioned above the shaft 100 as shown in FIG. 6 (referred to as the second posture). When the plate-like member 11 takes the second posture, the plate-like member 11 and the extension plate 12 attached to the tip portion 11e thereof do not protrude beyond the track side end face of the platform H toward the track side. Therefore, even if the gap between the train 3 running on the track and the platform H varies, the train will not collide with the transfer machine 1.

[0043] In addition, among the plate-shaped members 11 when taking the second posture, the surface 11f in the +x direction may be supported by the upper surface of the excavated portion of the home H when the plate-shaped member 11 takes the first posture. At this time, the surface 11f may be composed of two or more ribs extending from the shaft 100 to the tip 11e. In this case, the surface 11f is supported by the excavated upper surface of the home H when the plate-shaped member 11 takes the first posture. However, since the position of the rib having the surface 11f in the y-axis direction does not overlap with the pedal 101, the pedal 101 is not pressed downward.

[0044] FIG. 7 is a view of the plate-shaped member 11 in the second posture as viewed in the -x direction. The plate-shaped member 11 has a surface facing downward (that is, in the -z direction) in the first posture facing the track side (that is, in the +x direction) in the second posture. That is, FIG. 7 shows the surfaces of the plate-shaped member 11 and the extension plate 12 that face downward in the first posture.

[0045] <Configuration of the attachment / detachment mechanism of the transfer machine 1> FIG. 8 is a view showing the attachment / detachment mechanism of the extension plate 12 to the plate-shaped member 11. FIG. 8 shows an enlarged view of the region R shown in FIG. 7.

[0046] As shown in FIG. 8, in the region R, the extension plate 12 has a shaft pin 120, a connecting member 121, a spring 122, and a guide pin 123.

[0047] The shaft pin 120 is a rod-shaped member inserted substantially perpendicular to the extension plate 12 and functions as a central axis that supports the connecting member 121 so as to be swingable along the plane of the extension plate 12. The connecting member 121 has a lever 121a that an operator such as a station attendant, a crew member, or a passenger grasps and moves in the direction of the arrow shown in FIG. 8, and an engaging portion 121e that extends substantially at a right angle to the lever 121a and has a hook provided at the tip. The spring 122 biases the connecting member 121 clockwise as shown in FIG. 8. Therefore, as shown in FIG. 8, the engaging portion 121e is inserted into a hole 111 formed in the rib of the plate-shaped member 11. Thereby, the extension plate 12 is attached to the plate-shaped member 11, and the movement in the z-axis direction shown in FIG. 8 is restricted.

[0048] At the tip 11e of the plate-like member 11, there is a guide hole 112 drilled in the z-axis direction shown in FIG. 8. When the guide pin 123 is inserted into this guide hole 112, the position of the extension plate 12 in the x-axis direction and the y-axis direction in FIG. 8 is determined, and its movement is restricted.

[0049] FIG. 9 is a view showing the state when the lever 121a is moved in the direction of the arrow in FIG. 8. When the lever 121a is moved in the direction of the arrow in FIG. 8 against the biasing force of the spring 122, the connecting member 121 rotates counterclockwise as shown in FIG. 8 about the shaft pin 120. Then, when the engaging portion 121e of the connecting member 121 disengages from the hole 111, the restriction in the z-axis direction shown in FIG. 8 is removed, and the extension plate 12 becomes movable in the z-axis direction. Thereby, the extension plate 12 can be detached from the plate-like member 11.

[0050] FIG. 10 is a view showing the state where the extension plate 12 is detached from the plate-like member 11. As described above, the operator can detach the extension plate 12 of the transfer machine 1 from the plate-like member 11 as shown in FIG. 10 by rotating the connecting member 121.

[0051] Therefore, the shaft pin 120, the connecting member 121, and the guide pin 123 that the extension plate 12 has are a detaching and attaching mechanism that enables the extension plate 12 to be detachably attached to the plate-like member 11.

[0052] That is, this transfer machine 1 is an example of a transfer machine in which a plate-like member supported at the base along an axis along the home and having a detachably attached extension plate at the tip is rotated by this axis so that the tip is directed toward the boarding and alighting opening of the train in the first posture when the train stops, and the tip is directed above the axis in the second posture when the train is running.

[0053] With this configuration, for the extension plate 12 attached to the tip of the plate-like member 11 of the transfer machine 1 to cover the gap (for example, 120 millimeters or more and less than 200 millimeters) to the entrance and exit of the train 3 during parking, passengers are prevented from falling into this gap. Note that the extension plate 12 does not need to cover all of the gap and does not need to enter the vehicle from the entrance and exit of the train 3. The gap between the extension plate 12 and the entrance and exit may be, for example, less than 50 millimeters.

[0054] Also, since this extension plate 12 can be removed from the plate-like member 11, for example, even if the transfer machine 1 breaks down, the extension plate 12 can be removed from the plate-like member 11 to avoid contact with the train 3 during running.

[0055] <Configuration of the release mechanism of the transfer machine 1> FIG. 11 is a diagram showing the configuration of the release mechanism of the transfer machine 1. As shown in FIG. 11, the housing 10 of the transfer machine 1 has a shaft 100 and a pedal 101. The rib of the plate-like member 11 has a surface 11f shown in FIG. 11. This surface 11f is the surface that contacts the upper surface of the home H when the plate-like member 11 is in the first posture. However, since the rib having the surface 11f is arranged so that the positions in the y-axis direction do not overlap with the pedal 101, the pedal 101 is not pushed downward by the surface 11f.

[0056] FIG. 12 is a conceptual diagram of the pedal 101 viewed in the +y direction. The pedal 101 is on the track side, that is, on the side of the train 3, rather than the plate-like member 11 standing in the second posture. Here, the track side is the +x direction. Therefore, the pedal 101 is pushed down, for example, by the foot of an operator who has boarded the train 3 or is near the entrance and exit.

[0057] The +x-direction end of the pedal 101 is swingably fixed to the home H by a shaft 101a. Since the pedal 101 is biased in the direction of the arrow shown in FIG. 12 by an elastic member (not shown) such as a spring, the -x-direction end floats above the home H, and there is a so-called "stepping margin".

[0058] FIG. 13 is a diagram for explaining the configuration of the lock mechanism. The fixed portion 14 has a cam 140 and a restraining member 141. The cam 140 is housed in the fixed portion 14, connected to the shaft 100, and provided to rotate about this shaft 100. The position of the cam 140 shown in FIG. 13 is the position when the shaft 100 positions the plate-like member 11 in the second posture.

[0059] The restraining member 141 is provided so as to be swingable about the shaft 141a. The shaft 141a is connected to the above-described shaft 101a by a reverse rotation link mechanism. Thereby, when an elastic member (not shown) biases the pedal 101 in the direction of the arrow shown by the broken line in FIG. 13 about the shaft 101a, the restraining member 141 is biased in the direction of the arrow shown by the solid line in FIG. 13 about the shaft 141a. That is, when the pedal 101 is biased clockwise in the xz plane shown in FIG. 13 by the reverse rotation link mechanism, the restraining member 141 is biased counterclockwise in the same xy plane.

[0060] As a result, the tip 141e of the restraining member 141 enters a portion closer to the shaft 100 than the maximum diameter of the cam 140. Therefore, the cam 140 bears on this tip 141e, and the clockwise rotation shown in FIG. 13 is stopped. Since the cam 140 is interlocked with the shaft 100, the rotation of the shaft 100 is stopped by the stoppage of the rotation of the cam 140, and the posture of the plate-like member 11 interlocked with the shaft 100 is fixed in the second posture. That is, the restraining member 141 is a lock mechanism that maintains the posture of the plate-like member 11 in the second posture.

[0061] FIG. 14 is a view showing a state where the lock of the cam 140 is released. When the operator depresses the pedal 101, the pedal 101 rotates in the direction of the arrow shown by the broken line in FIG. 14 against the biasing force described above. Then, the restraining member 141 rotates in the direction opposite to this rotation direction, that is, in the arrow direction D1 shown by the solid line in FIG. 14. As a result, the tip 141e of the restraining member 141 moves to a portion farther from the shaft 100 than the maximum diameter of the cam 140. Therefore, the cam 140 moves away from this tip 141e and rotates in the arrow direction D2 shown by the solid line in FIG. 14, that is, clockwise about the shaft 100. Thereby, the posture of the plate-like member 11 interlocked with the shaft 100 becomes the first posture. That is, the pedal 101 is a release mechanism that moves the restraining member 141 to disconnect the contact with the cam 140 and thereby releases the lock of the plate-like member 11 in the second posture.

[0062] Therefore, this transfer machine 1 has a locking mechanism for fixing the plate-like member in the second posture, and the locking mechanism is an example of a transfer machine that can be released from the train side. With this configuration, in the event of a failure or the like, the operator can release the locking mechanism from the side of the train 3 and direct the tip portion 11e of the plate-like member 11 toward the boarding and alighting opening of the train 3.

[0063] <Operation of the Transfer Machine Control Device C1> FIG. 15 is a flowchart showing an example of the operation of the transfer machine control device C1 that controls the transfer machine 1. The processor of the transfer machine control device C1 determines whether or not the train sensor E3 has detected a normal stop of the train 3 based on the information exchanged with the operation management device C3 (step S101). While it is determined that the normal stop of the train 3 has not been detected (step S101; NO), the transfer machine control device C1 continues this determination. When it is determined that the normal stop of the train 3 has been detected (step S101; YES), the transfer machine control device C1 sets the plate-like member 11 to the first posture in which the tip portion 11e thereof faces the boarding and alighting opening of the train 3 (step S102). Thereby, the plate-like member 11 of the transfer machine 1 and the extension plate 12 attached to the tip portion 11e of this plate-like member 11 extend in the x-axis direction, that is, in a substantially horizontal direction, and are in a state of bridging the home H and the boarding and alighting opening of the train 3 (also referred to as a bridging state).

[0064] When the plate member 11 assumes the first posture, the transfer control device C1 instructs the operation management device C3 to open the boarding and alighting doors of the train 3 (step S103). Then, the transfer control device C1 instructs the platform gate control device C2 to open the platform gate (step S104).

[0065] As a result, the boarding and alighting doors of the train 3 and the platform gate are opened. Since the plate member 11 and the extension plate 12 in the transfer machine 1 are in the above-described bridging state, passengers such as wheelchair users can board and alight through the boarding and alighting doors without falling into the gap between the platform H and the train 3.

[0066] Next, the transfer control device C1 determines whether the passenger sensor E1 is detecting a passenger (step S105). Here, while the transfer control device C1 determines that the passenger sensor E1 is detecting a passenger (step S105; YES), this determination continues. On the other hand, when it is determined that the passenger sensor E1 no longer detects a passenger in the vicinity of the plate member 11, for example, over a determined period (step S105; NO), the transfer control device C1 instructs the platform gate control device C2 to close the platform gate (step S106), and further instructs the operation management device C3 to close the boarding and alighting doors of the train 3 (step S107). As a result, the passage for passengers from the platform H to the train 3 formed by the plate member 11 and the extension plate 12 in the first posture is blocked.

[0067] When the above-described passage is blocked, the transfer control device C1 changes the tip 11e of the plate member 11 to the second posture in the +z direction of the shaft 100, that is, upward (step S108). As a result, the plate member 11 and the extension plate 12, which were in the horizontal bridging state and forming the passage, become in the vertical state of so-called spring-up bridge, so these members become a "wall" that crosses the passenger passage and obstructs its passage.

[0068] Therefore, for example, even if a wheelchair or a stroller advances in the +x direction of the home H when the home fence 2 fails and does not close, it collides with the plate-shaped member 11 or the like in the second posture and stops, so that it is prevented from falling to the track side. Further, for example, even if the home H has no home fence 2 installed, a visually impaired person can confirm the end on the track side of the home H by touching the tip of a white cane against the plate-shaped member 11 in the second posture and in a jumping state.

[0069] When the plate-shaped member 11 assumes the second posture, the boarding and alighting control device C1 gives an instruction to the operation management device C3 to permit the running of the train 3 (step S109). As a result, the train 3 is permitted to run and runs under the operation of the driver.

[0070] With the operation described above, when the train 3 has stopped normally, the boarding and alighting device 1 sets the plate-shaped member 11 to the first lateral posture. Triggered by the plate-shaped member 11 assuming the first posture, the boarding and alighting openings of the train 3 and the home fence 2 open, so that passengers can move back and forth between the home H and the stopped train 3 and board and alight from the train 3.

[0071] Further, triggered by the fact that the passengers are not detected for a determined time near the plate-shaped member 11 in the first posture, the home fence 2 and the boarding and alighting openings of the train 3 close, so that the risk of the passengers coming into contact with and being pinched by the home fence 2 and the train 3 is avoided.

[0072] That is, since the boarding and alighting control device C1, the home fence control device C2, and the operation management device C3 construct an interlock mechanism that interlocks according to the conditions based on the detection results, the management system 9 can safely board and alight the passengers and safely run the train 3.

[0073] The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, and can be changed into various forms without departing from the scope of the technical idea shown in the claims.

[0074] <Modification> The above is a description of the embodiment, but the contents of this embodiment can be modified as follows. In addition, the following modifications can be combined.

[0075] <1> In the above-described embodiment, the transfer device control device C1 opens the train 3 entrance and exit gates and the platform fence 2 when the plate-shaped member 11 assumes the first position. However, the transfer device control device C1 may also open the train 3 entrance and exit gates and the platform fence 2 when the plate-shaped member 11 is fixed in the first position. In this case, for example, the tip 141e of the stopping member 141 shown in FIG. 14 may exceed the maximum diameter of the cam 140 rotating clockwise and enter a portion close to the shaft 100, thereby stopping the cam 140 from rotating counterclockwise. In this way, the stopping member 141 fixes the plate-shaped member 11, which is linked to the cam 140, in the first position.

[0076] The fixing unit 14 may detect the positions of the cam 140 and the stopping member 141 using a contact sensor, an infrared sensor, or the like, to detect that the plate-like member 11 has been fixed in the first position. The transfer machine control device C1 may receive the detection result and control the boarding / alighting entrance and the platform fence 2 described above.

[0077] The transfer device 1 in this modified example is an example of a transfer device that opens a platform fence provided at a position corresponding to the entrance and exit on the platform when the plate-like member is fixed in the first position.

[0078] <2> In the above-described embodiment, when the plate-shaped member 11 assumes the second posture, the boarding control device C1 gives an instruction to the train operation management device C3 to permit the running of the train 3. However, when the plate-shaped member 11 is fixed in the second posture by the above-described locking mechanism, an instruction to permit the running of the train 3 may be given. In this case, the fixing portion 14 may detect the positions of the cam 140 and the restraining member 141 by means of a contact-type sensor, an infrared sensor, or the like, and detect that the plate-shaped member 11 is fixed in the second posture. The boarding control device C1 may give the above-described instruction to permit the running of the train 3 in response to this detection result.

[0079] The boarding machine 1 in this modification example is an example of a boarding machine in which the locking mechanism permits the running of a stopped train when the plate-shaped member is fixed.

[0080] <3> In the above-described embodiment, when it is detected that a passenger has not been detected for a determined time near the plate-shaped member 11 in the first posture, the boarding control device C1 gives an instruction to the platform gate control device C2 and the train operation management device C3 to close the platform gate 2 and the entrance / exit of the train 3. However, when it is detected that a passenger has not been detected for a determined time on the plate-shaped member 11 fixed in the first posture by the locking mechanism, the platform gate 2 and the entrance / exit of the train 3 may be closed.

[0081] In this case, when the boarding control device C1 detects that the plate-shaped member 11 is fixed in the first posture by means of a contact-type sensor, an infrared sensor, or the like, the passenger sensor E1 is activated, and an infrared sensor or the like included in the passenger sensor E1 monitors above the plate-shaped member 11 to detect the presence or absence of a passenger.

[0082] The boarding machine 1 in this modification example is an example of a boarding machine that closes the platform gate provided at a position corresponding to the entrance / exit at the platform when there is no passenger on the plate-shaped member fixed in the first posture for a determined time.

[0083] <4> In the above-described embodiment, the detaching mechanism for making the extension plate 12 detachable from the plate-shaped member 11 rotates the connecting member 121 about the shaft pin 120 by operating the lever 121a to disengage the engaging portion 121e from the hole 111. However, the detaching mechanism is not limited to this configuration. For example, instead of the guide pin 123, a bolt may be inserted into the guide hole 112. In this case, the extension plate 12 may be attached to the plate-shaped member 11 by tightening a nut with the guide hole 112 interposed therebetween. In this case, the operator may detach the extension plate 12 from the plate-shaped member 11 by loosening the nut and removing it from the bolt.
