Description

  The present invention relates to an elevator door control device that controls opening and closing of an elevator door device.

  For example, a conventional elevator door control device as shown in Patent Document 1 is connected to a fully open position detection switch and a fully closed position detection switch for detecting that the door panel is in the fully open position and the fully closed position, respectively. Yes. These fully open position detection switches and fully closed position detection switches are mounted, for example, in a hanger case that houses a door hanger for hanging a door panel. Further, a small plate for operating the fully open position detection switch and the fully closed position detection switch is attached to the door hanger. The door control device detects that the door panel is in the fully open position or the fully closed position by contacting the small plate with the operating piece of the door fully open position detection switch or the fully closed position detection switch.

  Here, the fully open position detection switch and the fully closed position detection switch have two roles. The first role is the torque switching of the door motor by the door control device. The opening and closing movement of the door panel is mechanically prevented so as not to go beyond a preset operation limit position. When the door panel is prevented from opening and closing and the door motor is given a torque output command equivalent to the door opening or closing operation, the door motor may burn out. For this reason, it is necessary to switch the torque of the door motor.

  The second role is that when the door control device grasps the operating position of each switch in advance, the start of door opening deceleration or door closing deceleration can be set to an appropriate position. A signal of a pulse generator that generates a pulse corresponding to the rotation of the door motor is used for the control of the door opening deceleration or the door closing deceleration. Here, an example of the door opening deceleration operation will be described. Px is the number of pulses at the fully opened position, Py is the number of pulses corresponding to the deceleration distance set in advance from the type and door width of the door device, and P is the current number of pulses. Assume that each is set in the door control device. In such a case, the door control device grasps Px at the first door opening / closing after the power is turned on, and starts deceleration from the position of the pulse number P = Px−Py from the next door opening.

JP 2006-256849 A

The conventional elevator door control device as described above uses a fully open position detection switch and a fully closed position detection switch. Therefore, where these switches are mounted, the installation space for these multiple types of switches is not limited. It is necessary to ensure. In addition, in order to perform maintenance and inspection, it is necessary to consider the mounting position of the switch so that the operation position of the switch can be adjusted within the reach of the elevator landing.

  Furthermore, when refurbishing the control system of the door device using a mechanical component of the existing door device (such as a speed reduction mechanism or door hanger for transmitting the driving force of the door motor to the door panel), a fully open position detection switch and It may be necessary to replace the fully closed position detection switch. In such a case, a new full-open position detection switch and a full-close position detection switch must be attached to the existing door device, which increases the work load. Similarly, the work load increases when the door device is installed.

  The present invention has been made in order to solve the above-described problems, and provides an elevator door control device capable of reducing the number of switches and reducing the work burden during installation and repair. With the goal.

Door control device for an elevator according to the present invention, a door position detection means for detecting that the door panel is in the predetermined reference position in the vicinity of the other hand or the fully open position and fully closed position Neu displacement movement of the door panel Connected to motor monitoring signal generating means for generating a motor monitoring signal corresponding to the amount of operation of the door motor corresponding to the amount, door position detecting means and motor monitoring signal generating means, and monitors the position and moving distance of the door panel. A door opening / closing control unit for controlling the opening / closing movement of the door panel, and the door opening / closing control unit is capable of executing a position capturing process for capturing a fully opened position and a fully closed position used for controlling the opening / closing movement of the door panel, running the position acquisition process moves the door panel to the respective mechanical operation limit position of full-opening-fully closed, the operating state of the door position detection means Measure the distance of the door panel movement from the reference position to each of the fully open side and fully closed side operation limit positions based on the motor monitoring signal. each capture the full-opening measured distance and fully closed the measured distance is to use a full-opening measured distance and fully closed the measured distance to control the opening and closing movement of the door panel.

  According to the elevator door control device of the present invention, the door opening and closing control unit determines the movement distance of the door panel from the reference position to the operation limit positions on the fully open side and the fully closed side, respectively, the fully open side actually measured distance and the fully closed side actually measured. Since the opening and closing movement of the door panel is controlled by using the distance measured as the distance and the measured distance between the fully opened side and the actually measured distance on the fully closed side, the fully open position detecting switch and the fully closed position detecting switch in the conventional elevator door control device become unnecessary. As a result, the number of switches can be reduced, and the work load at the time of installation and repair can be reduced.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a rear view showing an elevator car door apparatus according to Embodiment 1 of the present invention.
In FIG. 1, an elevator car doorway (not shown) is opened and closed by a car door device 1. The car door device 1 is a double door. The car door device 1 includes a hanger plate 2, a hanger rail 3, a pair of door hangers 4A and 4B, a pair of door panels 5A and 5B, a door motor 6, a speed reduction pulley 7, a first transmission belt 8, a driven pulley 9, and a second. A transmission belt 10 and a pair of gripping members 11A and 11B are provided.

  The hanger plate 2 is fixed to the upper part of the car. The hanger rail 3 is attached to the hanger plate 2. Moreover, the hanger rail 3 is arrange | positioned along the frontage direction of the car doorway. The pair of door hangers 4 </ b> A and 4 </ b> B are provided on the hanger rail 3. Each of the pair of door hangers 4A and 4B has a plurality of hanger rollers (not shown). These hanger rollers can roll on the hanger rail 3.

  The upper ends of the pair of door panels 5A and 5B are fixed to the lower ends of the pair of door hangers 4A and 4B, respectively. That is, the pair of door panels 5A and 5B are suspended from the hanger rail 3 via the pair of door hangers 4A and 4B, respectively. The door motor 6 is disposed on the upper surface of the hanger plate 2. The door motor 6 generates a driving force for opening and closing the pair of door panels 5A and 5B in response to an external command. Furthermore, the door motor 6 has a drive pulley.

  The deceleration pulley 7 is rotatably attached to one end of the hanger plate 2 in the length direction (the right end in FIG. 1). Moreover, the deceleration pulley 7 has a first outer peripheral surface and a second outer peripheral surface having a diameter smaller than that of the first outer peripheral surface. The first transmission belt 8 is wound endlessly on the outer peripheral surface of the drive pulley of the door motor 6 and the first outer peripheral surface of the deceleration pulley 7 so as to pass between the pulleys. That is, the deceleration pulley 7 is connected to the drive pulley of the door motor 6 via the first transmission belt 8. The driven pulley 9 is rotatably attached to the other end portion in the length direction of the hanger plate 2 (left end portion in FIG. 1).

  The second transmission belt 10 is wound endlessly on the second outer peripheral surface of the deceleration pulley 7 and the outer peripheral surface of the driven pulley 9 so as to pass between the pulleys. That is, the driven pulley 9 is connected to the deceleration pulley 7 via the second transmission belt 10. The upper end portion of the gripping member 11 </ b> A is connected to the upper path of the second transmission belt 10. The lower end portion of the gripping member 11A is connected to the door hanger 4A. The upper end portion of the gripping member 11B is connected to the lower path of the second transmission belt 10. The lower end of the gripping member 11B is connected to the door hanger 4B.

  Accordingly, the driving force from the door motor 6 is generated by the pair of door panels 5A and 5B via the first transmission belt 8, the deceleration pulley 7, the driven pulley 9, the second transmission belt 10, and the pair of gripping members 11A and 11B. Communicate to each of the. The pair of door panels 5 </ b> A and 5 </ b> B are opened and closed in opposite directions in the front / rear direction of the car doorway by the driving force of the door motor 6.

  The stopper 12 is attached to the other end portion in the length direction of the hanger plate 2 (left end portion in FIG. 1) adjacent to the driven pulley 9 of the hanger plate 2. The stopper 12 is for setting the fully open position of the pair of door panels 5A and 5B. Further, the stopper 12 abuts against an end of the door hanger 4A on the opening direction side, thereby restricting the movement of the door panel 5A from the fully opened position to the opening direction.

  Further, when the movement of the door panel 5 </ b> A in the opening direction is restricted by the stopper 12, the movement of the door panel 5 </ b> B in the opening direction is also restricted via the second transmission belt 10. That is, the position where the end of the door hanger 4A on the opening direction side and the stopper 12 abut is the operation limit position on the fully open side of the door panels 5A and 5B.

  On the other hand, when the ends of the pair of door panels 5A and 5B contact each other, movement of the pair of door panels 5A and 5B from the fully closed position further in the closing direction is restricted. That is, the position where the ends in the closing direction of the pair of door panels 5A and 5B abut is the operation limit position on the fully closed side.

  Here, the hanger plate 2 is provided with a near-close vicinity detection switch 13 as a door position detection means. A pressing plate 14 is attached to the door hanger 4A. The operating piece of the near-close detection switch 13 is pressed by the pressing plate 14 when the end of the door panel 5A in the closing direction is between the fully-closed position and the fully-closed position as the reference position. This fully closed position is a position away from the fully closed position by, for example, about 10 to 15 mm.

  When the operating piece of the near-close detection switch 13 is not pressed, the near-close detection switch 13 is OFF. When the operating piece of the near-close vicinity detection switch 13 is pressed, the near-close vicinity detection switch 13 is operated to be turned on. That is, when the end of the door panel 5A in the closing direction is between the fully closed position and the fully closed position, the fully closed detection switch 13 is turned on. On the other hand, when the end of the door panel 5A in the closing direction moves away from the fully closed position in the opening direction, the fully closed detection switch 13 switches from the ON state to the OFF state, that is, the operating state of the fully closed detection switch 13 Changes.

  Further, a door control device 15 as a door opening / closing control unit is provided at the upper part of the hanger plate 2 (the upper part of the car). FIG. 2 is a block diagram specifically showing the door control device 15 of FIG. FIG. 3 is a block diagram showing part III of FIG. 2 and 3, the door motor 6 and the near-close detection switch 13 are electrically connected to the door control device 15. The door control device 15 includes a CPU 15a, ROM 15b, RAM 15c, a pulse counter 15d as pulse counting means, a motor drive circuit 15e, and an input / output unit (not shown).

  The CPU 15a performs arithmetic processing based on a program stored in the ROM 15b, and controls the opening / closing of the car door device 1, that is, the opening / closing movement of the door panels 5A and 5B. Further, the CPU 15a controls the drive of the door motor 6 by sending a drive command to the motor drive circuit 15e. Further, the CPU 15a outputs a drive command (drive current) to the door motor 6 via the motor drive circuit 15e. In addition, the CPU 15a stores various variables used for arithmetic processing in the RAM 15c.

  The door control device 15 is electrically connected to a pulse generator 16 as a motor monitoring signal generating means. The pulse generator 16 is mechanically connected to the rotating shaft of the door motor 6. The pulse generator 16 generates a pulse signal (motor monitoring signal) corresponding to the operation amount of the door motor 6 corresponding to the movement amount of the door panel 5A. Further, the pulse signal generated by the pulse generator 16 is a two-phase signal of A phase and B phase as shown in FIG. The phases of the A-phase and B-phase pulse signals are shifted by 90 degrees, for example.

  The pulse counter 15d counts the number of pulses of the pulse signal and sends the count value (count value) P to the CPU 15a. Further, the pulse counter 15d detects the rising edge (or falling edge) of one of the A phase and B phase pulses of the pulse generator 16, and then detects the rising edge (or falling edge) of the other pulse. The rotation direction of the door motor 6 is determined.

  Further, the pulse counter 15 d increases or decreases the pulse count value P based on the determined rotation direction of the door motor 6. For example, when the opening direction of the door panels 5A and 5B is the forward rotation direction of the door motor 6, the pulse counter 15d increases the pulse count value P as the door motor 6 rotates in the forward rotation direction. On the other hand, the pulse counter 15d decreases the pulse count value P as the door motor 6 rotates in the reverse direction.

  Further, the pulse counter 15d resets the pulse count value P to 0 (preset initial value) when the near-close detection switch 13 is switched from one of the ON state and the OFF state to the other. Furthermore, the pulse counter 15d sends a pulse count value P to the CPU 15a at regular intervals. Based on the pulse count value P, the CPU 15a measures (monitors) the moving distance of the pair of door panels 5A and 5B.

  Further, the CPU 15a monitors the moving distance and position of the pair of door panels 5A and 5B based on the pulse count value P. Further, the CPU 15a executes a fully open position capturing process for capturing the fully open position of the door panel 5A (fully open position recognition mode) and a fully closed position capturing process for capturing the fully closed position (fully closed position recognition mode). It is possible.

  In the fully open position capturing process and the fully closed position capturing process, the CPU 15a opens and closes the door panels 5A and 5B at a lower speed than normal. Further, the CPU 15a grasps, as the fully closed position (reference position), a position where the operating state of the fully closed detection switch 13 has changed during the fully opened position capturing process or the fully closed position capturing process.

  Next, various parameters used for calculation processing of the door control device 15 (CPU 15a) will be described. FIG. 4 is an explanatory diagram for explaining various parameters used for the arithmetic processing of the door control device 15 of FIG. FIG. 4 schematically shows the relationship between the opening / closing movement range of the door panel 5A, the fully closed vicinity detection switch 13 (shown as SW in FIGS. 4 to 6), and the number of pulses.

  In FIG. 4, the calculation processing of the door control device 15 includes a fully closed theoretical pulse number P1 as a fully closed theoretical distance, a fully open theoretical pulse number P2 as a fully open theoretical distance, and a fully closed actual measurement distance as a total closed distance. The closed side actual measurement pulse number Pfcl and the full open side actual measurement pulse number Pfop as the full open side actual measurement distance are used as parameters.

  The fully closed theoretical pulse number P1 and the fully open theoretical pulse number P2 are theoretical values calculated in advance, and are stored in the ROM 15b. The fully closed theoretical pulse number P1 is a pulse number corresponding to the moving distance of the door panel 5A from the position near the fully closed position to the fully closed position. The fully open theoretical pulse number P2 is a pulse number corresponding to the moving distance of the door panel 5A from the position near the fully closed position to the fully open position. The fully closed theoretical pulse number P1 and the fully open theoretical pulse number P2 can be calculated based on the operating position of the near-close detection switch 13, the reduction ratio of the deceleration pulley 7, the entrance / exit width, and the like.

  The fully closed side actually measured pulse number Pfcl and the fully open side actually measured pulse number Pfop are actually measured values of the pulse number of the pulse signal by the pulse counter 15d. The fully closed side actually measured pulse number Pfcl and the fully open side actually measured pulse number Pfop are stored in the RAM 15c. The fully closed side actually measured pulse number Pfcl is a pulse number corresponding to the moving distance of the door panel 5A from the position near the fully closed position to the fully closed position. The fully open side actually measured pulse number Pfop is a pulse number corresponding to the moving distance of the door panel 5A from the position near the fully closed position to the fully opened position.

  Here, when the fully closed position capturing process is being executed by the CPU 15a, the pulse count value P (measurement of the moving distance of the door panel 5A) from the operating position of the fully closed proximity detection switch 13 to the operation limit position on the fully closed side is executed. Value) and the total closed side theoretical pulse number P1 are within a predetermined allowable range, the pulse count value P becomes the fully closed side actually measured pulse number Pfcl.

  Similarly, when the fully open position capturing process is executed by the CPU 15a, the pulse count value P from the operating position of the fully closed vicinity detection switch 13 to the fully open side operation limit position and the fully open side theoretical pulse number P2 Is within a predetermined allowable range, the pulse count value P becomes the fully-open side actually measured pulse number Pfop. The allowable range is a range of the number of pulses corresponding to the moving distance of the door panel 5A of, for example, about 5 mm from the fully closed theoretical pulse number P1.

  Next, the operation will be described. In response to the power supply of the elevator being turned on and the start command being issued from the elevator control panel, the door control device 15 executes a fully closed position taking process. FIG. 5 is a flowchart showing the operation of the door control device 15 of FIG. In FIG. 5, first, the door control device 15 confirms whether or not the near-close vicinity detection switch 13 is in an OFF state (step S11). At this time, when the near-close detection switch 13 is in the ON state, the door control device 15 determines that the door device 1 is in the closed state, so that the near-close detection switch 13 is in the OFF state. Then, the door motor 6 is caused to output torque in the opening direction (step S12).

  When the fully closed vicinity detection switch 13 is in the OFF state, the door control device 15 causes the door motor 6 to output a closing direction torque (step S13). Then, the door control device 15 checks whether or not the fully closed vicinity detection switch 13 has been switched from the OFF state to the ON state, and waits until the state of the fully closed vicinity detection switch 13 has been switched (step S14). When the near-close detection switch 13 is switched from the OFF state to the ON state, the door control device 15 resets the pulse count value P (step S15).

  Then, the door control device 15 confirms whether or not the pulse count value P is increasing or decreasing, and waits until the pulse count value P does not increase or decrease (step S16). At this time, if the increase or decrease of the pulse count value P is eliminated, the door control device 15 checks whether or not the difference between the pulse count value P and the fully closed theoretical pulse number P1 is within an allowable range (step S17).

  When the difference between the pulse count value P and the fully closed theoretical pulse number P1 exceeds the allowable range, the door control device 15 causes the door motor 6 to output the opening direction torque in order to perform the measurement again. (Step S12), the same operation is repeated. On the other hand, when the difference between the pulse count value P and the fully closed theoretical pulse number P1 is within the allowable range, the door control device 15 determines that the door device 1 is in the closed state and drives the door motor 6. While stopping, the pulse count value P is memorize | stored as a fully closed side actual measurement pulse number Pfcl (step S19). Thereby, the fully closed position capturing process is completed.

  Next, the door control device 15 executes the fully open position capturing process after the fully closed position capturing process. FIG. 6 is a flowchart showing the operation of the door control device 15 of FIG. In FIG. 6, the fully open position capturing process by the door control device 15 includes the points where the moving directions of the door panels 5A and 5B are opposite (steps S21 to S26 and S28), the pulse count value P, and the fully open side theoretical pulse number P2. Is different from the fully closed position capturing process in that it is confirmed whether or not the difference between them is within the allowable range (step S27) and the pulse count value P is stored as the fully open side measured pulse number Pfop (step S29). . Other operations are the same as the fully closed position capturing process shown in FIG.

  Here, when the fully closed position capturing process and the fully opened position capturing process are completed, the door control device 15 uses the fully closed side actual measurement pulse number Pfcl and the fully open side actual measurement pulse number Pfop captured during the processes. The door panel 5A, 5B is controlled to open and close. Specifically, the door control device 15 starts deceleration of the opening / closing movement of the door panels 5A and 5B at a position that is a predetermined number of pulses away from the fully closed side actually measured pulse number Pfcl or the fully open side actually measured pulse number Pfop. Further, the door control device 15 switches the torque of the door motor 6 from the opening / closing moving torque to the stationary torque when the pulse count value P reaches the fully closed actual measured pulse number Pfcl or the fully opened actual measured pulse number Pfop.

  According to the elevator door control device as described above, the door control device 15 executes the fully opened position capturing process and the fully closed position capturing process, whereby the fully opened side actually measured pulse number Pfop and the fully closed side actually measured pulse number Pfcl. Capture. Then, the door control device 15 controls the opening and closing movement of the door panels 5A and 5B using the fully open side actually measured pulse number Pfop and the fully closed side actually measured pulse number Pfcl. This configuration eliminates the need for the fully open position detection switch and the fully closed position detection switch in the conventional elevator door control device, thereby reducing the number of switches and reducing the work load during installation and refurbishment. it can.

  Further, the CPU 15a confirms whether or not the pulse count value P from the operating position of the full-close vicinity detection switch 13 to the full-close side operation limit position is within the allowable range of the full-close theoretical pulse number P1. At the same time, the CPU 15a confirms that the pulse count value P from the operating position of the fully closed vicinity detection switch 13 to the fully open side operation limit position is within the allowable range of the fully open side theoretical pulse number P2. With this configuration, even if the door panels 5A and 5B are not arranged at the fully closed position or the fully opened position due to some abnormality, the erroneous position due to the occurrence of the abnormality is avoided, The taking-in accuracy of the fully open position and the fully closed position can be improved.

  Here, the pulse count value P is read by the CPU 15a, but since the pulse count value P is sent from the pulse counter 15d to the CPU 15a at a fixed period, the operation timing of the near-close detection switch 13 and the transmission of the pulse count value P are sent. There may be a time lag between the timing and an error. On the other hand, in the elevator door control device as described above, the pulse counter 15d detects the pulse count value when the operating state of the near-close detection switch 13 changes from one of the ON state and the OFF state to the other. P is reset to 0, and the number of pulses is counted based on the operating position of the near-close detection switch 13. With this configuration, it is possible to minimize the occurrence of temporal errors included in the pulse count value P.
