Description

  The present invention relates to an elevator door control device for controlling the operation of a car door provided in a car.

  In general, an elevator is a car traveling in a hoistway, a car door provided in the car, a door contact portion that abuts when the car door is closed, and a door contact portion side of the car door. And a door control device for controlling the opening / closing operation of the car door according to the presence / absence of detection of the foreign object detection device.

  Specifically, for example, when a passenger getting in or out of a car or a carried-in item comes into contact with a car door that is closed, the passenger or the carried-in item is detected by the foreign object detection device. At this time, the door control device controls the door safety or the like that reverses the car door from the door closing operation to the door opening operation. Thereby, when a car door closes, a passenger, a carried-in thing, etc. are prevented from being pinched | interposed between a car door and a door stop part.

  However, when the foreign object is a passenger or a carry-in object, the passenger or the carry-in object has a certain size and is detected relatively easily by the foreign object detection device. If the cords or pet lead wires are thin and soft string-like bodies, the foreign object detection device does not react or is recognized as an error even if these string-like bodies come into contact with the car door. There was a fear. In the unlikely event that these string-like bodies are not detected by the foreign object detection device, the door-control device does not control door safety or the like, and the string-like bodies are sandwiched between the car door and the door stop. It was conceivable that the car would go up and down in a state that was not desirable in the operation of the elevator, so it was necessary to prevent this.

  Therefore, a car that moves up and down the hoistway, a first door main body that has a first door closing side end and opens and closes an entrance between the car and the landing, the first door closing side when the door is closed A second door closing end that hits the end, and a second door body that opens and closes the doorway, so that the door is sandwiched between the first and second door closing end when the door is closed. A plurality of pressure sensors continuously provided along at least one of the first and second door closing side end portions along the longitudinal direction of the first and second door closing side end portions; An elevator apparatus including an opening / closing control unit that controls opening / closing of the first and second door bodies in response to a signal has been proposed as one of the prior arts (see, for example, Patent Document 1).

  As another prior art, at least one set of conductors is arranged so that the end of the door side of the car door faces the door stop, and the conductors are connected in series when the door is closed. There has also been proposed an elevator door safety device having a configuration in which conductors are connected so as to form a circuit, and an energization detecting means for detecting whether the series circuit can be energized when the door is closed (for example, a patent) Reference 2).

JP 2006-89251 A JP 2010-37015 A

  However, in the conventional elevator apparatus disclosed in Patent Document 1 described above, when the car door, that is, the first door main body or the second door main body is inclined even a little, these first door main bodies are provided. When the second door body is closed, the door bodies are not completely closed, and a gap is generated between the door closing side ends of the door bodies. Therefore, even if there is a thin flexible string-like body between the door closing side ends of each door body, this string-like body is provided at the door closing side end of the first door body or the second door body. Since it does not contact a plurality of pressure sensors, there is a problem that each pressure sensor cannot accurately detect the string-like body.

  Further, in the elevator door safety device of the prior art disclosed in Patent Document 2, when the car door is tilted even a little, the car is closed when the car door is closed as in the above-described prior art elevator device. The door does not completely close to the door stop, and a gap is generated between the car door and the door stop. For this reason, even if there is no thin flexible string-like body between the car door and the door stop, a pair of conductors provided at the end of the car door and the door stop are in contact with each other. Therefore, there is a problem that foreign matter is erroneously detected by detecting that the energization detecting means cannot energize.

  Here, when the car door is tilted, the above-described pressure sensor corresponding to the foreign object detection device and the energization detecting means are tilted so that the foreign object such as a thin flexible string can be detected accurately. It is necessary to adjust the parallelism to return the car door to parallel. This parallelism adjustment is performed by, for example, confirming the parallelism indicating whether or not the car door is parallel to the horizontal plane after the adjustment plate is inserted and tightened into the joint between the car door panel and the door hanger. Is adjusted several times. Therefore, even if parallelism adjustment is performed on a car door that is tilted, as described above, the parallelism adjustment is performed based on the experience and sense of the operator who determines the inclination of the car door. There is a concern that it takes a lot of time to check the parallelism associated with the adjustment and that the inclination of the car door cannot be adjusted accurately.

  The present invention has been made based on the actual situation of the prior art as described above, and its purpose is to adjust the inclination of the car door quickly and accurately, and to increase the detection accuracy of the foreign object detection device. It is to provide a control device.

  In order to achieve the above object, an elevator door control device according to the present invention includes a car door provided in the car, a door that abuts when the car door is closed, as well as a car traveling in a hoistway. The foreign object is applied to an elevator including a contact part and a foreign object detection device that is provided along the vertical direction at an end of the car door on the door contact part side and detects a foreign object that contacts the end part. In an elevator door control device that controls the opening / closing operation of the car door according to the presence / absence of detection by a detection device, a door opening / closing speed control unit that controls the speed of the car door; and the foreign object detection device at the door stop portion; A plurality of jigs provided so as to face each other; a sensor detection unit that detects a time difference when the foreign object detection device detects the plurality of jigs as foreign objects when the car door is closed; and the door opening Based on the detected time difference by the speed and the sensor detecting portion of the car door, which is controlled by the speed control unit is characterized in that a door inclination calculating unit for calculating a tilt of the car door.

  In the present invention configured as described above, since the plurality of jigs are provided in the door stop portion so as to face the foreign object detection device of the car door, the car door is closed and the foreign object detection device is attached to the plurality of jigs. Upon contact, these jigs are detected as foreign matter. Here, when the car door is inclined, the timing at which the foreign object detection device detects these jigs is different, and this timing depends on the speed of the car door. That is, if the speed of the car door and the time difference at which the foreign object detection device detects a plurality of jigs as foreign objects can be known, the inclination of the car door can be accurately grasped.

  Therefore, in the present invention, the door opening / closing speed control unit controls the speed of the car door, and the sensor detection unit detects the time difference at which the foreign object detection device detects a plurality of jigs as foreign objects. What is necessary for calculating the inclination of the door can be obtained as an actual measurement value. The door inclination calculation unit adjusts the car door by the calculated inclination by calculating the inclination of the car door from the speed of the car door controlled by the door opening / closing speed control unit and the time difference detected by the sensor detection unit. As a result, it is not necessary to repeat the confirmation work associated with the adjustment of the parallelism of the car door, and the time spent for this confirmation work can be saved. Thus, the inclination of the car door can be adjusted quickly and accurately, and the detection accuracy of the foreign object detection device can be increased.

  In the elevator door control device according to the present invention as set forth in the invention described above, the door opening / closing speed control unit sets the speed of the car door to a very low speed. With this configuration, the door opening / closing speed control unit allows the car door to travel at a very low speed, so that the time difference detected by the sensor detection unit can be widened. Accuracy can be increased.

  In the elevator door control device according to the present invention as set forth in the invention described above, the plurality of jigs comprise a pair of protrusions protruding toward the foreign object detection device. With this configuration, when the car door is closed, the foreign object detection device concentrates and receives the pressing force from the tip of the projection of the door stop portion, so that the detection reaction in the foreign object detection device can be enhanced.

  In the elevator door control device according to the present invention, in the above invention, a car door dimension value recording unit for storing a dimension value of the car door according to a model of the car door, and the car door dimension value recording unit A car door dimension value selecting means for selecting a dimension value of the car door by inputting a model of the car door, a dimension value of the car door selected by the car door dimension value selecting means, and the door And a parallelism adjustment amount calculation unit that calculates a parallelism adjustment amount of the car door based on the inclination of the car door calculated by the inclination calculation unit.

  In the present invention configured as described above, the dimension value of the car door is stored in the car door dimension value recording unit in accordance with the model of the elevator car door. By inputting the model of the car door, the dimension value of the car door can be taken out from the car door dimension value recording section and referred to. Here, when the parallelism adjustment amount is expressed by, for example, the number of adjustment plates to be inserted into the connecting portion between the car door panel and the door hanger, the parallelism adjustment amount calculation unit selects the car door dimension value selection means. The number of plates for adjustment can be calculated based on the size value of the car door selected by the above and the inclination of the car door calculated by the door inclination calculating unit. The inclination of the car door can be easily adjusted by simply inserting it into the joint between the panel and the door hanger.

  According to the elevator door control device of the present invention, the sensor detection unit detects the time difference that the foreign object detection device that is generated when the car door is tilted detects the plurality of jigs, and the door tilt calculation unit is the door opening / closing speed control unit. Since the car door tilt is calculated based on the speed of the car door controlled by the sensor and the time difference detected by the sensor detection unit, the car door is adjusted only by the calculated tilt. It is not necessary to repeat the confirmation work accompanying the adjustment of the parallelism of the door, and the time spent for this confirmation work can be saved. That is, the inclination of the car door can be sufficiently determined by the door inclination calculation unit without depending on the experience and feeling of the worker. In this way, the inclination of the car door can be adjusted quickly and accurately, and the detection accuracy of the foreign object detection device can be increased, so that the door control device can control the opening / closing operation of the car door more stably than before. Can be executed.

It is a figure which shows the structure of one Embodiment of the door control apparatus of the elevator which concerns on this invention. It is a figure explaining the structure of the parallelism calculating apparatus in this embodiment.

The door hanger 10 is coupled to the upper portion of the car door 1 via, for example, a pair of shaft bars (not shown) arranged along the belt 9c, and the pair of shaft bars are arranged in the vertical direction of the car door 1. It arrange | positions so that it may become object mutually with respect to the centerline which follows, and the space | interval of the car door 1 and the door hanger 10 can be adjusted with the adjusting plate mentioned later.

  The door control device 5 according to the present embodiment is connected to a door motor 9, and controls the operation of the door motor 9 to control the opening / closing operation of the car door 1. The door control device 5 is installed at the top of the car 1A. In this embodiment, for example, when a passenger gets in the car 1A and operates the destination floor button on the operation panel and then presses the close button among the open / close buttons, the door control device 5 drives the door motor 9 to drive the drive pulley 9a. Rotate.

  As a result, the belt 9c rotates in the same direction as the rotation direction of the drive pulley 9a with the rotation of the drive pulley 9a, the driven pulley 9b slidingly contacting the belt 9c rotates, and the door hanger 10 engaged with the belt 9c is moved. The car door 1 is closed. When the car door 1 is completely closed, the control panel drives the hoist to raise and lower the car 1A, so that the car 1A moves to the destination floor designated by the destination floor button.

  In the present embodiment, the elevator includes a plurality of foreign object detection devices that are provided at the end of the car door 1 on the door stop 3 side and detect foreign objects that have come into contact with the end. These plurality of foreign matter detection devices are composed of, for example, three pressure sensitive sensors 2 that detect the pressing force received on the surface, and these three pressure sensitive sensors 2 are arranged in a line along the vertical direction. Has been placed.

  The door control device 5 controls the opening / closing operation of the car door 1 in accordance with the presence or absence of foreign matter detected by the three pressure-sensitive sensors 2. For example, when the car door 1 is closed, The door safety is controlled so that the car door 1 is opened when a load or the like comes into contact with the car door 1.

  That is, when a passenger or a load or the like comes into contact with the pressure sensor 2 while the car door 1 is closed, the pressure sensor 2 detects the pressing force because the contact pressure acts on the surface of the pressure sensor 2. To do. And the door control apparatus 5 will perform control which switches the door closing operation | movement of the car door 1 to a door opening operation | movement, if the detection of the foreign material by the pressure sensor 2 is received.

  In the present embodiment, as described above, the three pressure-sensitive sensors 2 are arranged in a line along the vertical direction, so that a thin soft material as a foreign object is temporarily placed between the car door 1 and the door stop 3. Even when there is a string-like body, the car-shaped door 1 is opened by contacting the string-like body with one of these three pressure-sensitive sensors 2.

  Here, when the car door 1 is tilted due to secular change, foreign objects coming into contact with the car door 1, or the like, parallelism adjustment is performed to return the tilted car door 1 to parallel. In the present embodiment, the parallelism adjustment is performed, for example, by holding the pair of shaft rods between the panel of the car door 1 and the door hanger 10 with the gap between the car door 1 and the door hanger 10 open. This is performed by interposing the plates 11 and adjusting the number of adjusting plates 11 to be interposed in the respective shaft rods.

  The door control device 5 according to the present embodiment includes a door opening / closing speed control unit 6 that controls the speed of the car door 1, and a plurality of below-described jigs that are provided on the door stopper 3 so as to face each pressure sensor 2. The plurality of jigs include a pair of protrusions 4 protruding toward the pressure sensor 2, for example. The pair of protrusions 4 are spaced apart from each other, one of which contacts the uppermost pressure-sensitive sensor 2 when the car door 1 is closed, and the other the door 1 is closed. At the time, the pressure sensor 2 at the bottom is brought into contact.

  In addition, the door control device 5 includes a sensor detection unit 7 that detects a time difference when each pressure-sensitive sensor 2 detects the pair of protrusions 4 as foreign matters when the car door 1 is closed, and a door opening / closing speed control unit. And a door inclination calculation unit 8 for calculating the inclination of the car door 1 on the basis of the speed of the car door 1 controlled by 6 and the time difference detected by the sensor detection unit 7. Further, the door opening / closing speed control unit 6 sets the speed of the car door 1 to a very low speed, for example.

  Specifically, the height of the car door 1 panel is Hm, the speed of the car door 1 controlled by the door opening / closing speed control unit 6 is Vmm / s (constant), and the distance between the pair of protrusions 4 is Lm. When the door 1 is closed, the uppermost pressure sensor 2 detects the upper protrusion 4 first, and after Ts, the lower pressure sensor 2 detects the lower protrusion 4. Then, the sensor detection part 7 detects Ts as a time difference which each pressure-sensitive sensor 2 detected a pair of projection part 4 as a foreign material.

At this time, the inclination θ of the car door 1 calculated by the door inclination calculation unit 8 is the difference between the constant speed V of the car door 1 controlled by the door opening / closing speed control unit 6 and the time difference T detected by the sensor detection unit 7. It is represented by a function, that is, the following equation (1).

  Accordingly, the height H of the car door 1 panel is set to 2 m, the speed V of the car door 1 controlled by the door opening / closing speed control unit 6 is set to 1 mm / s (constant), and the distance L between the pair of protrusions 4 is set to 1 m. When the time difference T detected by the sensor detection unit 7 is 1 s, the inclination θ of the car door 1 calculated by the door inclination calculation unit 8 is 2 mm.

  Moreover, the door control apparatus 5 which concerns on this embodiment is connected to the door inclination calculating part 8 as shown in FIG. 2, and calculates the parallelism which represents the parallelism showing whether the car door 1 became parallel with respect to the horizontal surface. An arithmetic device 12 is provided. Specifically, the parallelism computing device 12 is equipped with computing software 15 that performs calculations using various parameters such as the inclination θ of the car door 1 and the dimension value of the car door 1 as described later.

  The calculation software 15 stores a car door dimension value management unit 13 that manages on the software the dimension value of the car door 1 such as the height H of the car door 1 panel provided in the elevator as a parameter. The car door dimension value management unit 13 stores, for example, a car door dimension value recording unit 16 that stores the dimension value of the car door 1 in accordance with the model of the car door 1, and the car door dimension value recording unit 16 And a car door dimension value selecting means 17 for selecting the dimension value of the car door 1 by inputting the model number 1.

  Further, the calculation software 15 determines the car door 1 based on the dimension value of the car door 1 selected by the car door dimension value selection means 17 and the inclination θ of the car door 1 calculated by the door inclination calculation unit 8. A parallelism adjustment amount calculation unit 14 for calculating the parallelism adjustment amount is stored.

  In the present embodiment, the parallelism adjustment amount calculation unit 14 adjusts the adjustment plates 11 to be interposed in the respective shaft rods based on the size values of the car door 1 selected by the car door size value selection means 17 and the thickness of the adjustment plate 11, for example. The inclination of the car door 1 is calculated on the software in accordance with the number of sheets. Therefore, when the inclination θ of the car door 1 calculated by the door inclination calculation unit 8 is input to the parallelism adjustment amount calculation unit 14, the number of adjustment plates 11 to be interposed in each shaft rod corresponding to the inclination θ. Is calculated.

  According to the present embodiment configured as described above, the pair of protrusions 4 are arranged so as to be spaced apart from each other so as to face the uppermost pressure sensor 2 and the lowermost pressure sensor 2 of the car door 1. Since the car door 1 is closed and these pressure-sensitive sensors 2 come into contact with the protrusions 4, the protrusions 4 are detected as foreign matters. Here, when the car door 1 is tilted, the timings at which the pressure sensors 2 detect these protrusions 4 are different, and this timing depends on the speed V of the car door 1. That is, if the speed V of the car door 1 and the time difference T at which each pressure-sensitive sensor 2 detects the pair of protrusions 4 as foreign substances can be known, the inclination θ of the car door 1 can be accurately calculated from the above equation (1). Can grasp.

  In this embodiment, the door opening / closing speed control unit 6 controls the speed V of the car door 1 to a constant speed, and then the time difference T at which each pressure-sensitive sensor 2 detects the pair of protrusions 4 as foreign matters is detected by the sensor detection unit. Therefore, what is necessary for calculating the inclination θ of the car door 1 can be obtained as an actual measurement value. Then, the door inclination calculation unit 8 uses the equation (1) to calculate the inclination θ of the car door 1 from the speed V of the car door 1 controlled by the door opening / closing speed control unit 6 and the time difference T detected by the sensor detection unit 7. Therefore, it is only necessary to adjust the car door 1 by the calculated inclination θ, so that it is not necessary to repeatedly perform the confirmation work associated with the parallelism adjustment of the car door 1, and the time spent for this confirmation work can be saved. Can do. In this way, the inclination of the car door 1 can be adjusted quickly and accurately, and the detection accuracy of the pressure-sensitive sensor 2 as the foreign object detection device can be increased, so that the door control device 5 opens and closes the car door 1. Can be stably executed.

  Further, according to the present embodiment, the door opening / closing speed control unit 6 causes the car door 1 to travel at a slow speed, so that the protrusion 4 at the top of the door-contacting unit 3 contacts the top pressure sensor 2 and the door. The timing at which the protrusion 4 at the lower part of the contact part 3 comes into contact with the pressure sensor 2 at the bottom is greatly shifted, and the time difference T detected by the sensor detection part 7 can be widened. That is, the time difference T becomes a larger value than when the car door 1 is driven at a normal speed, and the detection error of the sensor detection unit 7 can be reduced. Thereby, the calculation precision of the inclination of the car door 1 in the door inclination calculating part 8 can be improved.

  Further, in the present embodiment, since the pair of protrusions 4 protrude toward the uppermost pressure sensor 2 and the lowermost pressure sensor 2, the pressure sensor 2 when the car door 1 is closed. Receives concentrated pressure from the tip of the projection 4 of the door stop 3. Therefore, the detection reaction in the pressure sensor 2 can be enhanced, and the sensor detection unit 7 can improve the detection sensitivity of the time difference T in which each pressure sensor 2 detects the pair of protrusions 4 as foreign matters.

  Further, in the present embodiment, the dimension value such as the height H of the car door 1 is stored in the car door dimension value recording unit 16 of the car door dimension value management unit 13 according to the model of the car door 1. By inputting the model of the car door 1 that is the object of parallelism adjustment by the car door dimension value selection means 17, the height H of the car door 1 can be taken out from the car door dimension value recording unit 16 and referred to. . Therefore, since it is not necessary for the operator to check the height H of the car door 1 that is the object of parallelism adjustment in advance, it is possible to quickly start the parallelism adjustment work, which is excellent in convenience.

  Further, when the parallelism adjustment amount calculation unit 14 receives the inclination θ of the car door 1 calculated by the door inclination calculation unit 8, the number of adjustment plates 11 to be interposed in each shaft rod corresponding to the inclination θ. , The inclination of the car door 1 can be easily adjusted simply by interposing the calculated number of adjustment plates 11 on each shaft rod. Thereby, the high workability | operativity of the parallelism adjustment with respect to the car door 1 is securable.

  In addition, although this embodiment mentioned above demonstrated the case where the parallelism calculating device 12 was stored in the door control apparatus 5 of the upper part of the cage | basket | car 1A, it is not restricted to this case and an operator carries the parallelism calculating device 12. It may be mounted on a portable terminal such as a PC, and the portable terminal may be connected to the door inclination calculation unit 8 when adjusting the parallelism of the car door 1. This eliminates the need to store the parallelism calculation device 12 in the door control device 5 or to carry the parallelism calculation device 12 in addition to the portable terminal, so that the door control device 5 can be miniaturized and has excellent portability. Can be provided.

  Moreover, although this embodiment demonstrated the case where the three pressure sensors 2 were each provided in the edge part by the side of the door stop part 3 among the car doors 1 as a some foreign material detection apparatus, it is not restricted to this case, and a foreign material The detection device may be any device that can detect a foreign object that has come into contact with the end of the car door 1 on the door stop 3 side, and even if there are not three pressure sensors, one, two, or four or more pressure sensors are provided. Also good.
