JP 2007-313971 A

  However, in the conventional platform door apparatus, when a train enters a platform, all the door bodies are opened and closed simultaneously. That is, since the position of the door body is set in accordance with the door position of the train, there is a problem that the door position of the vehicle constituting the train entering the platform is limited to a predetermined one. That is, there is a problem that the platform door device cannot be installed on a platform in which, for example, a vehicle with three doors enters or a vehicle with four doors enters.

  Therefore, the present invention has been made in view of such a point, and an object of the present invention is to provide a platform door device that can be installed on a platform into which a vehicle with a different number of doors enters.

To achieve the above object, the present invention is installed on the platform, a platform screen door system for opening and closing a door opening by opening and closing the door body, each movable in the guide box and a pair of guide box A door body supported by the door, and driving the door body to open and close the first entrance / exit between the guide boxes, and one of the first home door units And a door body that is installed so as to form a second entrance / exit between the guide box and a door body that is movably supported by the door body so as to open and close the second entrance / exit. A door bag body installed so as to form a third entrance / exit between the home door unit and the other guide box of the first home door unit, and the door pocket so as to open / close the third entrance / exit A third home door unit having a door body supported so as to be movable, and when the entering vehicle has an odd number of entry / exit doors, the door body of the first home door unit is driven while the entering vehicle is an even number. A control unit that drives the door body of the second home door knit and the door body of the third home door unit when the door has a passenger door, and the width of the guide box is that of the first home door unit. The controller is configured to be shorter than the width of the door body, and the control unit, when opening and closing the first entrance / exit, opens the door body of the first platform door unit, the second platform door unit, and the third platform. By driving the door body of the home door unit synchronously, one door body of the first home door unit and the door body of the second home door unit are operated like one door. Both the home door apparatus that is operated as the first home door unit other door body and the third home door unit one door and a door body of the.

  In the present invention, when a vehicle having an odd number of entry / exit doors enters, the door of the first home door unit is driven to open / close, and the first entrance / exit is opened / closed at a position corresponding to the center of the vehicle. On the other hand, when a vehicle having an even number of entrance / exit doors enters, the door of the second home door unit is driven to open and close, and the door of the third home door unit is driven to open and close. As a result, the second entrance and the third entrance are opened and closed. These entrances are entrances adjacent to the first entrance. In other words, since the door body that opens and closes is changed according to the door position of the train to be entered, even when a train of a vehicle with a different number of doors enters the platform, the entrance / exit according to the door position is opened and closed. be able to. Therefore, according to the platform door device of the present invention, the platform door device can be installed on a platform into which vehicles with different numbers of doors enter.

  Moreover, in the present invention, while the first platform door unit is configured to be a double-drawing type, in the second and third platform door units, an entrance / exit is formed between the guide box of the first platform door unit. As shown, a door bag body is installed, and a door body for opening and closing the entrance is provided. That is, if the second and third home door units are configured to open and close the door body between the pair of door pockets in a double-drawing manner, the door bodies of the second and third home door units are the first home. Unlike the door unit, which is installed adjacent to the guide box of the door unit, in the present invention, the second and third home door units project the door body from one door bag body toward the guide box. Since it is set as a structure, it can avoid that a guide box and a door pocket body adjoin. For this reason, the first entrance / exit is set on one side of the guide box and the second entrance / exit (or the third entrance / exit) is set on the other side. (Or the third entrance / exit) can be prevented from expanding the interval.

Furthermore , the width of the guide box is shorter than the width of the door body . For vehicles having an odd number of entry / exit doors with an entrance door at the center position of the vehicle and vehicles having an even number of entrance / exit doors set at a position shifted from the center position, the entrance / exit door position is near the center of the vehicle. In the present invention , the width of the guide box of the first home door unit can be shortened. Therefore, even if the position of the entrance door near the center is slightly shifted depending on the vehicle, the width depends on the position of the entrance door. This makes it easier to set the entrance / exit. In other words, the distance between the first entrance / exit and the second entrance / exit can be made smaller, and the distance between the first entrance / exit and the third entrance / exit can be made smaller.

Furthermore , when the control unit opens and closes the first entrance, the door of the first home door unit and the doors of the second home door unit and the third home door unit are opened. synchronization with you drive. In the first home door unit, the door butt of the door body protrudes from the guide box when the door body opens the first entrance, and the door body of the second home door unit and the third door body are synchronized with the door body. The door body of the home door unit moves in a direction toward the inside of the door pocket. For this reason, even if it is the structure where the door bottom of a door body protrudes from a guide box, it can prevent interfering with an adjacent door body. Accordingly, even if the door body of the first home door unit, the door body of the second home door unit, and the door body of the third home door unit are not offset in the thickness direction, these door bodies are close to each other. It becomes possible to arrange.

  The second home door unit has an end side door body that is movably supported by the door bag body, and the end side door body is configured to be able to advance from the door bag body on the side opposite to the door body, It is preferable that the door body and the end side door body supported by the door pocket body are displaced from each other in the thickness direction. In this aspect, by opening and closing the end side door body, it is possible to open and close the entrance / exit located on the end side of the vehicle relative to the second entrance / exit. And in the 2nd home door unit, since the door pocket body is shared with respect to two door bodies, it can suppress that the number of door pocket bodies increases. Furthermore, since the door body and the end side door body are displaced in the thickness direction, the door body and the end side door body can be stored so that they are aligned in the thickness direction in the door pocket body. For this reason, it can prevent that the width | variety of the door pocket body in the direction along a track | orbit becomes large.

In the present embodiment, the fifth entrance 25 is set at a position corresponding to the position of the front entrance door of the vehicle C. As shown in FIG. 1B, the second unit 14 and the third unit 16 are symmetrical in the positional relationship between the door bodies 14b and 16b and the end side door bodies 14c and 16c. Except for the same configuration.

  FIG. 1 shows a state in which a vehicle C with four doors enters, but when a vehicle C with three doors enters, the fourth entrance 24 is the last entrance door of the vehicle C. The fifth entrance 25 coincides with the front entrance door of the vehicle C.

  In the example shown in the figure, the door 12b, 14b, 16b and the end doors 14c, 16c of the first unit 12 to the third unit 16 have a configuration in which the transparent plate 29 is fitted. Is not something

  As shown in FIG. 3, the home door apparatus 10 includes a control unit 30 that can control opening and closing of the first entrance / exit 21 to the fifth entrance 25. The control unit 30 is provided as a function of the home door control device (general control panel) 32. The home door control device 32 is connected to a host system 34 such as ATO so as to be able to exchange signals, and is also connected to a handy operation box 36 so as to be able to exchange signals. The hand control box 36 means an operation panel operated by a crew member or an operation panel operated by a station worker. That is, the hand control box 36 may be installed on the platform P or may be installed on the train. The home door control device 32 is not limited to this configuration. For example, it may be electrically connected only to either the host system 34 or the hand control box 36.

  The home door control device 32 receives the train type signal S1, the train number signal S2, the opening command signal S3, the closing command signal S4, the emergency stop signal S5, and the fully opening signal S6 output from the host system 34 and the hand control box 36. To do. The home door control device 32 outputs an open position signal S11, a close position signal S12, a door failure signal S13, and a door trouble signal S14.

  Among the signals, the opening command signal S3, the train type signal S1, and the set number signal S2 are input to the platform door control device 32 via an AND circuit 38, for example, as shown in FIG. As the train type signal S1, there are a three-door signal indicating that the number of passenger doors is a vehicle C having three and a four-door signal indicating that the number of passenger doors is four. These three door signals or four door signals are output from the host system 34 or the hand control box 36 according to the number of doors of the vehicle C of the train to be entered. As the number-of-knitting signals S2, 4-car train signals, 6-car trains, 7-car trains, 8-car trains, 10-car trains, or 12-car trains, respectively, 4-car train signals, 6-car train signals, 7 cars There are a knitting signal, an 8-car train signal, a 10-car train signal, and a 12-car train signal. These formation signals are output from the host system 34 or the hand control box 36 in accordance with the train formation to be entered. Then, if the train to be entered is, for example, an eight-car train with three doors, only the three-door eight-car opening signal is turned on by the AND circuit 38, so the platform door control device 32 has a boarding / alighting gate corresponding to the turned-on signal. A control signal is transmitted to each of the units 12, 14, and 16 to open and close 21, 24, and 25. Thereby, the entrances 21-25 according to the train organization of a train can be opened and closed.

  Here, the opening / closing pattern of the entrances 21-25 by the platform door apparatus 10 of this embodiment is demonstrated, referring Fig.5 (a)-(c). Although this figure shows only one vehicle, the same operation is performed for the other vehicles C. This open / close pattern is an example.

  In this description, for convenience, the door bodies 14c, 14b, 12b, 12b, 16b, and 16c are referred to as door 1 to door 6 in order from the rear side of the train (left side in the figure). That is, the pair of door bodies 12b, 12b of the first unit 12 is the door 3 and the door 4, the door body 14b of the second unit 14 is the door 2, the end side door body 14c of the second unit 14 is the door 1, The door body 16 b of the third unit 16 is referred to as a door 5, and the end side door body 14 c of the third unit 16 is referred to as a door 6.

  FIG. 5A shows a state where the train has not yet entered, the doors 1 to 6 are all in the closed position, and the first entrance 21 and the fifth entrance 25 are all closed. In addition, the arrow in Fig.5 (a) represents the direction which opens a door.

  When a train consisting of a vehicle C with three doors enters, a three-door signal is output as a train type signal S1 from the host system 34 or the hand control box 36, and an open command signal S3 is synchronized with the stop of the train. Is output. As the formation number signal S2, a signal corresponding to the vehicle formation is output. Thereby, as shown in FIG.5 (b), the 1st entrance / exit 21, the 4th entrance / exit 24, and the 5th entrance / exit 25 are open | released.

  Specifically, when the door 3 and the door 4 move to the open position, the first entrance 21 is opened. At this time, the door 2 moves in synchronization with the door 3, and synchronizes with the door 4. The door 5 moves. That is, since the door bottom of the door 3 is in contact with the door tip of the door 2, when the door 3 opens, the door 2 is driven to prevent the interference between the two. The amount of movement of the door 2 at this time is the same as the amount of movement of the door 3. Therefore, the door 2 and the door 3 operate as if they are one door. The relationship between the door 4 and the door 5 is the same.

  Further, the door 1 and the door 6 move from the closed position to the open position. As a result, the fourth entrance / exit 24 and the fifth entrance 25 are opened. Then, in response to the closing command signal S4, the doors 1 to 6 perform a closing operation, and the entrances 21, 24, and 25 are closed.

  On the other hand, when a train consisting of a vehicle C having four doors enters, a four-door signal is output from the host system 34 or the hand control box 36, and an opening command signal S3 is output in accordance with the stop of the train. The As the formation number signal S2, a signal corresponding to the vehicle formation is output. Thereby, as shown in FIG.5 (c), the 2nd entrance / exit 22 and the 3rd entrance / exit 23, the 4th entrance / exit 24, and the 5th entrance / exit 25 are opened. That is, when the door 1, door 2, door 5 and door 6 move from the closed position to the open position, the entrances 22 to 25 are opened.

  As described above, in this embodiment, when the vehicle C having an odd number of entrance / exit doors enters, the door body 12b of the first unit 12 is driven to open and close, and the first entrance / exit 21 at a position corresponding to the center of the vehicle C. Is opened and closed. On the other hand, when the vehicle C having an even number of entry / exit doors enters, the door body 14b of the second unit 14 is driven to open and close, and the door body 16b of the third unit 16 is driven to open and close. Thereby, the 2nd entrance / exit 22 and the 3rd entrance 23 are opened and closed. These entrances 22 and 23 are entrances adjacent to the first entrance 21. That is, since the door body that opens and closes is changed according to the door position of the train to be entered, even when a train of a vehicle C having a different number of doors enters the platform P, the entrance / exit corresponding to the door position is changed. Can be opened and closed. Therefore, it can be installed on the platform P into which the vehicle C having a different number of doors enters.

  In addition, in the present embodiment, the first unit 12 is configured to be a double-drawing type, while the second and third units 16 have the entrances 22 and 23 between the first unit 12 and the guide box 12a. Door pocket bodies 14a and 16a are installed so as to be formed, and door bodies 14b and 16b for opening and closing the entrances 22 and 23 are provided. That is, if the second and third units are configured to open and close the door body between the pair of door pockets in a pulling manner, the door pockets of the second and third units are the guide boxes of the first unit 12. Unlike this, in the present embodiment, the second and third units 14 and 16 are doors from one door bag body 14a and 16a toward the guide boxes 12a and 12a. Since the bodies 14b and 16b protrude, the guide boxes 12a and 12a and the door pockets 14a and 16a can be avoided from being arranged adjacent to each other. For this reason, the first entrance 21 is set on one side of the guide box 12a, and the second entrance 22 (or the third entrance 23) is set on the other side. And the second entrance / exit 22 (or the third entrance / exit 23) can be prevented from expanding.

  Moreover, the door bodies 12b and 12b are respectively supported by the pair of guide boxes 12a and 12a, and the door bodies 14b, 14c, 16b and 16c are 1 on both sides of the common door bag bodies 14a and 16a. Since it has a simple configuration of combination with the platform door units 14 and 16 arranged one by one, an existing platform door unit can be used.

  Moreover, in this embodiment, when the door body 12b of the 1st unit 12 opens the 1st entrance / exit 21, the door butt protrudes from the guide box 12a. In the vicinity of the center of the vehicle C, the vehicle C having an odd number of entrance doors with the entrance door at the center position of the vehicle C and the vehicle C having an even number of entrance doors where the entrance door is set at a position shifted from the center position. Although the entrance / exit door position is slightly displaced, in this embodiment, the width of the guide box 12a of the first unit 12 can be shortened, so even if the entrance / exit door position near the center is slightly displaced by the vehicle C, It becomes easy to set the entrance / exit at a position corresponding to the position of the entrance door. In other words, the distance between the first entrance / exit 21 and the second entrance 22 can be made smaller, and the distance between the first entrance / exit 21 and the third entrance 23 can be made smaller.

  Further, in the present embodiment, in the first unit 12, when the door body 12b opens the first entrance 21, the door bottom of the door body 12b protrudes from the guide box 12a, but in synchronization with the door body 12b. The door body 14b of the second unit 14 and the door body 16b of the third unit 16 move in a direction toward the inside of the door pocket bodies 14a, 16a. For this reason, even if it is the structure where the door bottom of the door body 12b protrudes from the guide box 12a, it can prevent interfering with the adjacent door bodies 14b and 16b. Accordingly, the door bodies 12b, 14b, and 16b of the first unit 12 are not offset in the thickness direction of the door body 12b of the second unit 14, the door body 14b of the second unit 14, and the door body 16b of the third unit 16. Can be arranged so as to be close to each other.

  Moreover, in this embodiment, in the 2nd unit 14 (3rd unit 16), the end side of the vehicle C rather than the 2nd entrance / exit 22 (3rd entrance 23) by opening and closing the end side door bodies 14c and 16c. It is possible to open and close the entrances 24 and 25 located at the same position. Moreover, in the second unit 14 (third unit 16), since the door pockets 14a (16a) are shared by the two door bodies 14b, 14c (16b, 16c), the number of the door pockets 14a (16a) Can be prevented from increasing. Furthermore, since the door body 14b (16b) and the end side door body 14c (16c) are displaced in the thickness direction, the door body 14b (16b) is arranged so that they are aligned in the thickness direction in the door bag body 14a (16a). ) And the end side door body 14c (16c). For this reason, the width | variety of the door pocket body 14a (16a) in the direction along a track | orbit can be prevented from becoming large.

Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, the door 12b of the first unit 12 and the door 14b of the second unit 14 are in contact with each other, but the door 12b of the first unit 12 and the door 14b of the second unit 14 are in the thickness direction. It is good also as composition which has shifted .

  Although the case where all the vehicles C constituting the train have the same number of doors has been described, when the train is formed by vehicles C having different numbers of doors, it can be dealt with by changing the entrances that open and close for each vehicle C. is there.
