Description

  The present invention relates to an elevator control device with door opening / closing control, and more particularly, to an elevator control device with opening / closing control of an elevator door in which a landing door is configured by a driving door and a driven door that opens and closes in conjunction with the driving door. .

  In elevator doors, particularly on landing side doors, the driven side doors are opened and closed by interlocking with the driving side doors and ropes. However, in the unlikely event that the rope is cut due to wear or the like, the door on the driving side is fully closed, but the car may run without the door on the driven side being fully closed.

  Therefore, when the driving door and the driven door are normally fully closed, the magnetic door is located inside one of the adjacent doors, and the magnetic door is located inside the other door. There is a conventional technique for detecting a state in which the driven door is fully closed by having a light emitting part inside one of the nearby doors and a light receiving part at a position facing the light emitting part of the other door (for example, Patent Document 1).

  Hereinafter, preferred embodiments of an elevator control device of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a typical configuration diagram of an elevator control device according to Embodiment 1 of the present invention, and shows a configuration of an elevator car as viewed from the front. FIG. 1 includes a car sill 1, a car door 2, a car door device 3 for driving the car door 2, a girder 4, and reflected light detection sensors 9 and 10.

  The present invention relates to a fully-closed position detecting means for detecting whether or not a driven door is in a predetermined fully-closed position in an elevator having a landing door composed of a driving door and a driven door that opens and closes in conjunction with the driving door. Is provided on the car side. The reflected light detection sensors 9, 10 in FIG. 1 correspond to this fully closed position detecting means. Further, the reflected light detection sensor 9 corresponds to a first detection means, and the reflected light detection sensor 10 corresponds to a second detection means.

  The reflected light detection sensors 9, 10 play the following roles, respectively. The reflected light detection type sensor 9 as the first detection means is attached to the upper part of the beam 4 and includes a plurality of light projecting parts and light receiving parts. The reflected light detection sensor 9 detects a state in which the follower door of the landing door is fully closed mainly when the car starts to move in the DOWN direction.

  On the other hand, the reflected light detection sensor 10 as the second detection means is attached to the lower part of the car sill 1 and includes a plurality of light projecting parts and light receiving parts. The reflected light detection sensor 10 detects a state in which the follower door of the landing door is fully closed mainly when the car starts to move in the UP direction.

Next, specific operations of the reflected light detection sensors 9, 10 will be specifically described with reference to the positional relationship with the landing door.
First, the specific operation of the reflected light detection sensor 10 will be described. FIG. 2 is an explanatory diagram of the operating principle of the reflected light detection type sensor 10 attached to the lower part of the car sill 1 according to Embodiment 1 of the present invention, and the configuration of the reflected light detection type sensor 10 viewed from the side. Is shown.

  FIG. 2A shows a state where the elevator car is stopped at the stop position of the floor, and FIG. 2B shows a state after the elevator car starts to move in the UP direction. . 2A and 2B, the right side is the elevator car side, and the car sill 1, the car door 2, and the reflected light detection sensor 10 are shown. On the other hand, in FIGS. 2A and 2B, the left side is the landing side, and the landing threshold 11, the driving door 12 on the landing side, and the driven door 13 on the landing side are shown.

  2A, since the reflected light detection sensor 10 is attached to the lower part of the car sill 1, the front of the reflected light detection sensor 10 becomes the lower part of the landing sill 11 or the hoistway wall when stopped. For this reason, the reflected light detection sensor 10 can receive the irradiated light as light reflected on the lower part of the landing sill 11 or the hoistway wall. In the state of FIG. 2A, the open / close state of the driving door 12 on the landing side and the driven door 13 on the landing side cannot be detected, but whether or not the reflected light detection type sensor 10 can correctly detect the reflected light (that is, Whether the reflected light detection sensor 10 is functioning normally).

  Next, in FIG. 2B, when the elevator car starts to move in the UP direction, the front surface of the reflected light detection sensor 10 moves to the lower part of the door on the landing side of the floor where it has stopped. For this reason, when both the driving door 12 and the driven door 13 are fully closed, the reflected light detection sensor 10 can receive the irradiated light as light reflected on the landing door.

  Next, FIG. 3 is an explanatory view of the operation principle of the reflected light detection type sensor 10 attached to the lower part of the car sill 1 according to Embodiment 1 of the present invention. As shown in FIG. 2 shows a configuration in which the periphery of the reflected light detection type sensor 10 is viewed from the upper surface in a state after the movement starts in the UP direction.

  FIG. 3A shows a normal state in which the driven door 13 is fully closed. FIG. 3B shows that the interlocking rope connected to the driving door 12 is cut off, so that the driving door 12 is fully closed. In this case, the driven door 13 is not fully closed. 3A and 3B, the upper side is the elevator car side, and the car sill 1, the car door 2, and the reflected light detection sensor 10 are shown. On the other hand, in FIGS. 3A and 3B, the lower side is the landing side, and the landing threshold 11, the driving door 12 on the landing side, and the driven door 13 on the landing side are shown.

  After the elevator car starts to move in the UP direction, as shown in FIG. 3A, in order to detect a normal state in which the landing-side driven door 13 is fully closed, the reflected light detection type sensor 10 It is necessary to mount at least one light projecting unit for each door (the driving door 12 on the landing side and the driven door 13 on the landing side).

  In the case of FIG. 3 (a), since it is a double door, one is installed in the center of the entrance for each door, the reflected light detection sensor 10a corresponding to the driving door 12 on the landing side, and the landing side The reflected light detection type sensor 10b corresponding to the driven door 13 is provided. Since there is a landing door (the driving door 12 on the landing side and the driven door 13 on the landing side) in front of each light projecting unit, the reflected light detection sensors 10a and 10b both receive the light reflected by the landing door at the light receiving unit. Can receive light.

  On the other hand, after the elevator car starts to move in the UP direction, as shown in FIG. 3B, the interlocking rope connected to the driving door 12 on the landing side is cut, so that the driving door 12 is fully closed. Nevertheless, when the driven door 13 is not fully closed, the reflected light detection sensor 10b cannot receive the light reflected by the landing-side driven door 13 by the light receiving unit. That is, since the reflected light detection sensor 10a has the driving door 12 in front of the light projecting unit, the light reflected by the driving door 12 can be received by the light receiving unit. However, since the reflected light detection sensor 10b does not have the driven door 13 in front of the light projecting unit, the light reflected by the driven door 13 cannot be received by the light receiving unit.

  Next, a specific operation of the reflected light detection sensor 9 will be described. FIG. 4 is an explanatory diagram of the operation principle of the reflected light detection type sensor 9 attached to the upper part of the beam 4 in the first embodiment of the present invention, and shows the configuration of the periphery of the reflected light detection type sensor 9 as seen from the side. Show.

  FIG. 4A shows a state where the elevator car is stopped at the stop position of the floor, and FIG. 4B shows a state after the elevator car starts to move in the DOWN direction. . 4A and 4B, the right side is the elevator car side, and the car door 2, the girder 4, and the reflected light detection sensor 9 are shown. On the other hand, in FIGS. 4A and 4B, the left side is the landing side, and the driving door 12 on the landing side and the driven door 13 on the landing side are shown.

  In FIG. 4A, the reflected light detection type sensor 9 is attached to the upper part of the girder 4. Therefore, when stopped, the front surface of the reflected light detection type sensor 9 becomes the hoistway wall. For this reason, the reflected light detection sensor 9 can receive the irradiated light as light reflected by the hoistway wall. In the state of FIG. 4A, the open / close state of the driving door 12 on the landing side and the driven door 13 on the landing side cannot be detected, but whether or not the reflected light detection sensor 9 can correctly detect the reflected light (that is, whether or not the reflected light is detected). Whether the reflected light detection sensor 9 is functioning normally) can be confirmed.

  Next, in FIG.4 (b), if an elevator car begins to move to a DOWN direction, the front of the reflected light detection type sensor 9 will move to the upper part of the door on the landing side of the floor where it stopped. For this reason, when both the driving door 12 and the driven door 13 are fully closed, the reflected light detection sensor 9 can receive the irradiated light as light reflected by the landing door.

  On the other hand, when the interlocking rope connected to the driving door 12 on the landing side is cut, the driven door 13 is not fully closed although the driving door 12 is fully closed. ), The reflected light detection type sensor 9a (not shown) corresponding to the driving door 12 on the landing side can receive the reflected light, but the reflected light detection type sensor 9b (corresponding to the driven door 13 on the landing side). (Not shown) cannot receive reflected light.

  Based on the detection results of the reflected light detection sensors 9 and 10, a drive control unit (not shown) that performs door opening / closing drive control and car lift control performs the following control. When the elevator car starts to move in the DOWN direction from the stopped state, the drive control unit monitors the detection state of the reflected light detection type sensor 9.

  And a drive control part is prescribed | regulated in order to detect whether it is a door closed state by the predetermined time slot | zone (namely, the reflected light detection type sensor 9 which is a 1st detection means) after the DOWN run start of an elevator car. As an example, the reflected light detection type sensor 9 is in an undetected state in a time zone defined by a predetermined interval after a predetermined time has elapsed after starting to move in the DOWN direction, and the landing side driven If the normal state in which the door 13 is fully closed cannot be detected, the elevator car is stopped.

  In this case, the predetermined time zone means that both the driving door 12 on the landing side and the driven door 13 on the landing side are in the closed state as shown in FIG. This corresponds to a time zone in which the detection type sensor 9 can reliably detect. Further, the drive control unit moves the elevator car back to the previous stop floor position (moves in the UP direction) and stops it.

  On the contrary, when the elevator car starts to move in the UP direction from the stop state, the drive control unit monitors the detection state of the reflected light detection type sensor 10. The drive control unit is defined to detect whether the door is closed by a predetermined time zone after the elevator car starts UP (that is, the reflected light detection sensor 10 as the second detection means). As an example, the reflected light detection type sensor 10 is in an undetected state in a time zone defined by a predetermined interval after a predetermined time has elapsed after starting to move in the UP direction, and the landing-side driven If the normal state in which the door 13 is fully closed cannot be detected, the elevator car is stopped.

  In this case, the predetermined time zone means that both the driving door 12 on the landing side and the driven door 13 on the landing side are in the closed state as shown in FIG. This corresponds to a time period during which the detection sensor 10 can reliably detect the time. Furthermore, the drive control unit moves the elevator car back to the previous stop floor position (moves in the DOWN direction) and stops it.

  Thus, when the state where the landing side driven door 13 is not fully closed is detected based on the detection results of the reflected light detection sensors 9, 10, and the elevator car is returned to the stop floor position, The drive control unit can notify the outside after making the passenger in the car quickly get off by announcing the abnormal state of the driven door 13 after opening the door.

  As described above, according to the first embodiment, the means for detecting the open / closed state of the landing-side drive door and the landing-side driven door of each floor is provided on the elevator car side, and the predetermined time zone after the start of elevator travel is provided. And the open / close state is checked. By having such a configuration, it is not necessary to process the landing doors, and the means for detecting the open / closed state of the landing doors on each floor can be shared, and only the car side needs to be processed. Detection means can be attached.

  In addition, by using two detection means (first detection means and second detection means) according to the direction of travel, the closed state of the landing door can be detected with high accuracy for both UP travel and DOWN travel. can do.
