Fig. 5 is the block diagram of the detailed structure of the arithmetical device 9 that had in the above-mentioned control device for elevator door 7 of expression.
Inside at arithmetical device 9, use the coder output 14B from coder 14A of expression electrical motor 11 rotating speeds, 19A calculates elevator door miles of relative movement 19B by elevator door miles of relative movement arithmetic section, and calculates elevator door speed 20B by elevator door speed arithmetic section 20A.In addition, inside at arithmetical device 9, come the value of computation speed instruction 16B by speed command arithmetic section 16A, and come the value of factored moment instruction 17B by torque command arithmetic section 17A, so that elevator door speed 20B is consistent with the value of speed command 16B, calculate the value of the motor current instruction 18B of the value that makes motor current 10B follow torque command 17B by motor current ordering calculation part 18A.And, inside at arithmetical device 9, value by 15 couples of torque command 17B of torque command value time diffusion arithmetic section is carried out time diffusion and the value of computing torque command value time diffusion 15B, come computing to represent to engage the engaging gap data 35B in gap 6 by engaging gap arithmetic section 35A according to the value of the torque command value time diffusion 15B that obtains by torque command value time diffusion arithmetic section 15A and the elevator door miles of relative movement 19B that obtains by elevator door miles of relative movement arithmetic section 19A, and its result is kept in the memory device 8.
Measurement as engaging gap 6, as mentioned above, be when cage side elevator door 1 and entrance hall side elevator door 2 are in that cage side elevator door 1 carries out opening action under the closed condition, measure the miles of relative movement of carrying out the cage side elevator door 1 of opening action when reaching state shown in Fig. 3 (b) from cage side elevator door 1.That is to say, sequential shown in Fig. 3 (b) and block diagram shown in Figure 5 are contrasted and can know, when the clamping close device 5A of the clamping close device 4 of cage side elevator door 1 and entrance hall side elevator door 2 comes in contact (collision), further increased the load that clamping close device 5A is promoted on electrical motor 11 at elevator door, change because of this load, the elevator door speed 20B of cage side elevator door 1 descends, when the value of speed command 16B becomes certain value, in order to compensate, the value of torque command 17B increases.Therefore, the time point that changes by the value that detects this torque command 17B, and calculate till from the elevator door full-shut position to this time point during in the value of the elevator door miles of relative movement 19B that moved of cage side elevator door 1, can access engaging gap data 35B.
Fig. 6 is the sequential chart that each required signal waveform of the measurement computing in the engaging gap 6 in the arithmetical device 9 of above-mentioned control device for elevator door 7 has been carried out contrast on time shaft.Fig. 6 (a) expression elevator door closed condition detection signal waveform 21B, Fig. 6 (b) expression speed command signal waveform 22 and elevator door speed signal waveform 23, Fig. 6 (c) expression torque command signal waveform 24, Fig. 6 (d) expression torque command value time diffusion signal waveform 25, Fig. 6 (e) expression elevator door miles of relative movement signal waveform 26.
Following on-off action according to elevator door changes the time dependent of each signal waveform and describes.In the starting stage, being in equitant position at cage side elevator door 1 and entrance hall side elevator door 2 promptly is under the elevator door full-shut position, be ON state (closed condition) by the elevator door closed condition detection signal waveform 21B that is arranged on the detected Fig. 6 of full close position switch 21A (a) on the cage side elevator door 1, and the torque command signal waveform 24 of Fig. 6 (c) is the state that elevator door is applied with certain moment values in order to keep the elevator door full-shut position on the elevator door closing direction, and it is zero state that the elevator door speed signal waveform 23 of while Fig. 6 (b) is elevator door speed 20B.Shown in Fig. 6 (a), when full close position switch 21A moves, at time point T0 to time point T1 during this, elevator door is failure to actuate, when having arrived time point T1, the elevator door overcome friction begins action, and to time point T2 during this, switch 21A is in disarmed state (idle state) at time point T1.
Under the complete closing state of elevator door, when making 1 action of cage side elevator door in order to form open mode, the value of the speed command 16B that time point T0 place output on the speed command signal waveform 22 of Fig. 6 (b) is certain, meanwhile, the torque command 17B of the specified value on the torque command signal waveform 24 of output map 6 (c).The situation that the value of torque command 17B changes to open mode from closed condition, the peak value at the time point T0 place of torque command value time diffusion signal waveform 25 that can be by Fig. 6 (d) is judged.
Reach at the elevator door speed 20B on the elevator door speed signal waveform 23 of Fig. 6 (b) till the value of speed command 16B during, the value of the torque command 17B on the torque command signal waveform 24 of Fig. 6 (c) continues to increase.At this moment, the mode of the increase of the value of the torque command 17B on the torque command signal waveform 24 of Fig. 6 (c) can be regulated by control constant among the moment ordering calculation part 17A is changed.Be specifically, in arithmetical device 9, for the precision of the increase of the value that improves torque command 17B, as the measurement dedicated mode in engaging gap 6, can set slow action model, the elevator door opening action that carries out according to the value of torque command 17B slowly be carried out by this slow action model.
After the value of the torque command 17B on the torque command signal waveform 24 of Fig. 6 (c) has reached more than a certain value, elevator door speed 20B on the elevator door speed signal waveform 23 of Fig. 6 (b) rises at time point T1 place, cage side elevator door 1 begins action, after this, time point T2 place on the elevator door closed condition detection signal waveform 21B of Fig. 6 (a), full close position switch 21A changes (OFF) state of closing into.
When the elevator door speed 20B on the elevator door speed signal waveform 23 of Fig. 6 (b) has reached the value of the speed command 16B on the speed command signal waveform 22, time point T3 place on the torque command signal waveform 24 of Fig. 6 (c), the value of torque command 17B becomes certain value.
After this, when the clamping close device 5A of the clamping close device 4 of cage side elevator door 1 and entrance hall side elevator door 2 bumps, acting on elevator door increases with the load on the electrical motor 11, therefore, the value of the elevator door speed 20B on the elevator door speed signal waveform 23 of Fig. 6 (b) sharply diminishes at time point T4 place.At this moment, torque command arithmetic section 17A is for the value of the value close velocity instruction 16B that makes elevator door speed 20B, the value of torque command 17B on the torque command signal waveform 24 of Fig. 6 (c) is increased quickly, meanwhile, the value of the torque command value time diffusion 15B on the torque command value time diffusion signal waveform 25 of Fig. 6 (d) is increased to great value and is maximized.
When the value of this torque command value time diffusion 15B has reached maximum value, the value of elevator door miles of relative movement 19B on the elevator door miles of relative movement signal waveform 26 of engaging gap arithmetic section 35A output map 6 (e) is as engaging gap data 35B, and in the write store 8.Thus, during time point T1 beginning and end time point T4, in control device for elevator door 7, measure engaging gap 6.Be specifically, in arithmetical device 9, the increase of the value of the torque command 17B the when variation of calculating the value of torque command 17B as the time diffusion characteristic, the clamping close device 4 of judging cage side elevator door 1 with the maxim of time diffusion characteristic (value of torque command value time diffusion 15B) come in contact with the clamping close device 5A of entrance hall side elevator door 2.When measuring engaging gap 6, if measure according to elevator door speed, then having oscillating component when measuring sneaks into, and when measuring according to torque command, because torque command is a control command, its signal waveform is level and smooth, so the survey precision when measuring according to elevator door speed is different.In the present embodiment, by using the derivative characteristic of this torque command, can further measure effectively.
In addition, at time point T5 place, clamping close device 5A slides and with clamping close device 5B (collision) takes place to contact for the second time, identical with contact (collision) for the first time, elevator door speed 20B on the elevator door speed signal waveform 23 of Fig. 6 (b) sharply diminishes, maximization appears in the value of the torque command value time diffusion 15B on the torque command value time diffusion signal waveform 25 of Fig. 6 (d), and the elevator door miles of relative movement 19B on the elevator door miles of relative movement signal waveform 26 of the value of the torque command 17B on the torque command signal waveform 24 of Fig. 6 (c) and Fig. 6 (e) further increases simultaneously.
Fig. 7 is the diagram of circuit that the action of expression arithmetical device 9 when engaging clearance measurement handled.
As the measuring process in engaging gap 6, at first, in control device for elevator door 7, set the order (step S27) that the engaging clearance measurement is begun.The setting of this order is undertaken by being arranged on the function part (switch of mechanical type or electronic type or action button etc.) that being used in the control device for elevator door 7 indicate execute card to close the clearance measurement dedicated mode, undertaken after the indicative of settings by function part is operated, automatically carry out the surveying work in the engaging gap 6 of following explanation by arithmetical device 9, and the data in the engaging gap 6 that will measure are kept in the memory device 8.
Then, whether whether arithmetical device 9 be in the ON state, export as the value of torque command 17B and make whether cage side elevator door 1 is that zero these three projects judge whether elevator door is in closed condition (step S28) towards certain moment and the elevator door speed 20B that closing direction moves according to the elevator door full-shut position detection signal from the full close position switch 21A of cage side elevator door 1.
The result who judges if be not in full-shut position, then turn back to the order that the engaging clearance measurement is begun and sets step (step S27) after carrying out elevator door full cut-off action (step S34).Be in full-shut position if confirm as, then the value of the speed command 16B of torque command arithmetic section 17A in-to-in control constant and speed command arithmetic section 16A is carried out change setting, the value of speed command 16B is changed to the special-purpose action model of engaging gap 6 measurements, carry out dedicated action thus and set (step S29).Be specifically, because the distance in engaging gap is several millimeters, so different speed slowly makes elevator door carry out opening action when adopting with regular event.
After having carried out dedicated action setting (step S29), according to the action of the measurement special use that engages gap 6, make elevator door carry out opening action equally, under dedicated mode, carry out elevator door opening action (step S30) thus.So carrying out in the process of elevator door opening action, when the clamping close device 5A of the clamping close device 4 of cage side elevator door 1 and entrance hall side elevator door 2 comes in contact (collision), the value of the elevator door miles of relative movement 19B of the cage side elevator door 1 in the time of will reaching this state of contact (collision) is as the value in engaging gap 6, to engage gap data 35B by engaging gap arithmetic section 35A and be stored in the memory device 8, engage the measurement (step S31) in gap thus.
After engaging clearance measurement (step S31) finishes, because can the engaging gap data 35B of reading and saving in memory device 8, use it for demonstration etc. so can obtain engaging gap data (step S32).
After this; opening action is proceeded; when forming full-gear in 2 interlocks of cage side elevator door 1 and entrance hall side elevator door; make the value of the speed command 16B of moment ordering calculation part 17A in-to-in control constant and speed command arithmetic section 16A turn back to the setting value of common elevator door opening-closing action usefulness at this time point; return to common elevator door opening-closing pattern from the measurement dedicated mode in engaging gap 6; normally reply processing (step S33) thus, after this tenth skill.In addition, the action of the engaging clearance measurement in the arithmetical device 9 is herein handled and also can be carried out by the software programming program.
Generally speaking, the calculation function of the arithmetical device 9 of above-mentioned control device for elevator door 7 is: be arranged on clamping close device 4 and the clamping close device 5 (5A that are arranged on the entrance hall side elevator door 2 on the cage side elevator door 1 in measurement, 5B) when each elevator door is in the engaging gap 6 that is had under the closing state, judge whether to import the off-state (the ON status signal of the full close position detector switch 21A of cage side elevator door 1) of elevator door full-shut position detection signal respectively, and whether make this cage side elevator door 1 carry out that output has certain moment values on the direction of closing movement as the torque command value, judge simultaneously whether described elevator door speed is zero, confirm thus whether elevator door is in full-shut position, from confirm as be in full-shut position after, the variation of the torque command value when conduct enters into the elevator door opening action detects the clamping close device 4 of cage side elevator door 1 and the clamping close device 5 (5A of entrance hall side elevator door 2, during the increase of the torque command value that produces when 5B) being in contact with one another (T1～T4), as elevator door miles of relative movement 19B, measure the miles of relative movement of cage side elevator door 1, and measure engaging gap 6 according to the result of a measurement of the miles of relative movement of cage side elevator door 1.
