Example 1
Fig. 3 is the instruction diagram of controlling device for doors of the elevator of the invention process form 1, illustrates about each floor in the building that lift appliance is set to have or not the example that smoke shielding device is set.Under the situation of building shown in Figure 3,1 to 4 layer elevator floor stops is provided with smoke shielding device, and the stop more than 5 layers is not established smoke shielding device.Have or not the information of setting to be stored in advance in the such memory storage of ROM18b that controlling device for doors 17 comprised about the smoke shielding device of each floor.When car 8 rests against and is provided with 4 of smoke shielding device and stands layer by layer,, carry out the open and close controlling of stop door 3 and car door 9 according to the information of " smoke shielding device is arranged " of being stored in the memory storage in the controlling device for doors 17.Promptly utilize the control setup that constitutes by controlling device for doors 17 and door motor 13 etc., set the electromotor velocity or the torque limiter value of door motor 13, carry out the open and close controlling of stop door 3 and car door 9.Otherwise when car 8 rests against when 5 of smoke shielding device not being set standing layer by layer, the information of " the no smoke shielding device " stored according to memory storage is carried out the open and close controlling of car door 9 and stop door 3 by controlling device for doors.Like this, the switching of stop door 3 and car door 9 is the information that has or not smoke shielding device according to each floor that car 8 is stopped, and is carried out and the stop control corresponding of stopping by controlling device for doors.
According to example 1 of the present invention, then because relevant each floor has or not the information that smoke shielding device is set to be stored in advance in the memory storage that controlling device for doors 17 comprised, and the information that has or not according to each floor smoke shielding device that this memory storage is deposited, carry out the open and close controlling of stop door 3 and car door 9 by controlling device for doors, so can carry out the open and close controlling of optimal stop door 3 and car door 9 according to the stop that car 8 is stopped.Thereby, by the setting of the interval change of the smoke shielding device engaging control setup that for example only engages with stop door 3 or stop fixed body at smoke shielding device, just can all can be steadily with the stop of not setting and carry out the on-off action of stop door 3 reliably to the stop that smoke shielding device is provided with.
Example 2
Fig. 4 is the controlling device for doors instruction diagram of the elevator of the invention process form 2.Among the figure, when the torque waveform of door motor 13 effects when solid line 41 expression is provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, dotted line 42 expressions are not provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, at the torque waveform of door motor 13 effects that engage interval cooresponding interval with smoke shielding device.Utilize controlling device for doors to begin to carry out stop door 3 and car door 9 at closing time from full-gear, before beginning from closing the door to be engaged to the stop fixed body or stop door 3 of stop framework 1 grade to smoke shielding device, with have or not that smoke shielding device is set is irrelevant, difference does not take place in the torque of door motor 13 effects.But interval in the smoke shielding device engaging, according to having or not smoke shielding device is set, the torque of door motor 13 effects is different.Promptly, the stop of smoke shielding device is being set, owing to engaging with stop door 3 or stop fixed body, smoke shielding device produces resistance, so except the necessary torque of closing the door when smoke shielding device is not set, also need torque in the door motor 13 for the resistance of offsetting this engaging generation to stop door 3 and car door 9.Therefore the torque of the door motor 13 in the smoke shielding device engaging interval of the stop that smoke shielding device is set is compared when smoke shielding device is not set, and just shows bigger value.Therefore, in the such memory storage of the ROM 18b that controlling device for doors 17 is possessed, stored the torque threshold of the door motor 13 in the smoke shielding device engaging interval in advance, the torque detection value and the threshold value that in advance be stored in the torque of memory storage of the door motor of measuring when moving according to closing the door of stop door 3 and car door 9 13 in smoke shielding device engaging interval carried out the relevant judgement that smoke shielding device is set that has or not.
When the car 8 of elevator rests in certain stop, door motor 13 startings, the on-off action of execution stop door 3 and car door 9.This stop door 3 and car door 9 are when opening and closing, utilize measurement mechanism to measure the torque of door motor 13, and the maxim of the torque of door motor 13 that this measurement mechanism is measured, in the smoke shielding device engaging interval is stored among the RAM 18c that controlling device for doors 17 possessed.And in the memory storage of the ROM 18b that controlling device for doors 17 is possessed, be pre-existing in the torque threshold of the door motor 13 in the smoke shielding device engaging interval.The decision maker of the CPU18a that possesses in the controlling device for doors 17, whether torque maxim that the comparison measurement device is measured and the threshold value that is pre-stored in the torque of memory storage are provided with the judgement of smoke shielding device to the stop of car 8 stops.That is, the torque maxim of detection means measure is during less than the threshold value of torque, and decision maker judges that just this stop is not provided with smoke shielding device, during greater than the threshold value of torque, judges that this stop is provided with smoke shielding device.Detected each floor of detecting device that is made of this measurement mechanism and decision maker has or not the information of smoke shielding device, deposit memory storage in, when car 8 rests against this stop once more, the information of the relevant smoke shielding device of depositing according to memory storage of this floor, identical with example 1, carry out and the corresponding stop door of stopping 3 of stop and the open and close controlling of car door 9 by controlling device for doors.
According to example 2 of the present invention, then since the threshold value of the torque of storing in advance in the maxim of the torque of door motor 13 in smoke shielding device engaging interval that the decision maker that is possessed by controlling device for doors 17 is measured with measurement mechanism during to the on-off action of stop door 3 and car door 9 and the memory storage compare, can judge that each floor has or not is provided with smoke shielding device, even so after lift appliance is installed, also can finish the setting that each floor has or not smoke shielding device.Thereby,, also needn't change memory storage stored information, good operability even when floor is set changes of smoke shielding device taken place before lift appliance is installed.In addition, because storing each floor of being judged by decision maker in the memory storage has or not smoke shielding device is set, when stopping same floor once more, the information and executing stop door 3 that can smoke shielding device be set according to having or not of being stored in this memory storage and the open and close controlling of car door 9, therefore can be identical with example 1, can be steadily and carry out the on-off action of stop door 3 reliably.Again, in the example 2 owing to be the explanation of having closed the door the termination environment intercropping till finish to closing the door before closing the door to smoke shielding device engaging is interval, so measure the torque of the door motor 13 in closing the door between the termination environment, but, just can as long as engage the interval corresponding torque detection of doing with this smoke shielding device in the interval different occasion of smoke shielding device engaging.In addition also can be not only according to the maxim of torque, and wait according to the shape of torque waveform and inclination and to judge having or not of smoke shielding device.
Example 3
Fig. 5 is the instruction diagram of controlling device for doors of the elevator of the invention process form 3.Among the figure, when solid line 51 expression is provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, the torque waveform of door motor 13 effects, when dotted line 52 expressions are not provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, engage the torque waveform that door motor 13 acts in the interval cooresponding interval with smoke shielding device.Again, torque limiter waveform when torque limiter waveform when solid line 53 expression is provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, door motor 13, dotted line 54 expressions are not provided with the on-off action of carrying out stop door 3 and car door 9 in the stop of smoke shielding device, engage near the door motor 13 in interval cooresponding interval with smoke shielding device.The torque limiter of door motor 13 is the torque deficiencies for the door motor 13 in the on-off action that prevents stop door 3 and car door 9, sets the bigger value of the necessary torque of on-off action than stop door 3 and car door 9.But, for unlikely when elevator passenger is clamped by stop door 3 and car door 9 passenger is added excessive load, can not be too big with respect to the necessary torque of on-off action of stop door 3 and car door 9.Therefore green phase can be made steady and safe on-off action for the necessary torque settings of on-off action of stop door 3 and car door 9 within the specific limits.Again, in the stop of smoke shielding device is set, resistance takes place owing to smoke shielding device engages with stop fixed bodies such as stop door 3 or stop frameworks 1, thus interval in the smoke shielding device engaging that resistance takes place, set with the stop of not establishing smoke shielding device in the different value of torque limiter.That is, in smoke shielding device engaging interval, the value that the torque limiter in the stop of smoke shielding device is set is set greater than the value of the torque limiter in the stop of not establishing smoke shielding device.
According to the flow process of Fig. 6, illustrate that according to the torque limiter that has or not smoke shielding device to set door motor 13 be the control of asynchronous controlling device for doors 17.When the car 8 of elevator is stopped certain stop, be arranged at the floor (step S601) that the control housings 23 that wait in the hoistway 2 of elevator are just judged the stop that car 8 is stopped, the information of the floor that the controlling device for doors 17 output cars 8 that are located at car 8 are stopped.When control housing 23 was imported the floor information of cars 8 stops, controlling device for doors 17 judged that just according to the information that has or not smoke shielding device of each floor of storing in advance in the memory storage institute's stop floor has or not smoke shielding device (step S602).Here, when the floor that is judged as stop is not provided with smoke shielding device,, carry out the on-off action of stop doors 3 and car door 9 by door motor 13 just with the set condition of the torque limiter of common door motor 13 that smoke shielding device is not set.And when being judged as the storey setting smoke shielding device of stop, the information (step S603) of storage " smoke shielding device is arranged " in RAM 18c is to the torque limiter change setting (step S604) of door motor 13 that smoke shielding device is set.With the set condition of after changing torque limiter, by door motor 13 carry out the on-off action of stop doors 3 and car door 9 thereafter.
According to example 3 of the present invention, the then setting that has or not smoke shielding device to change the torque limiter of door motor 13 owing to the floor of stopping according to the car 8 of elevator is so can carry out the switching of stop door 3 and car 9 to the floor of each stop with suitable torque limiter.Promptly, engage interval at the stop that smoke shielding device is set with the smoke shielding device of the stop that is not provided with, different torque limiters being set, thus can not take place to make stop door 3 or car 9 cause vibration because of the torque deficiency of door motor 13, or under stop door 3 is closed the door completion status, form the gap.In addition,, also needn't worry the passenger to be acted on excessive load because of the torque of door motor 13 is excessive even when the passenger is clamped by stop door 3 or car door 9, can be steadily and carry out the switching of stop door 3 and car door 9 safely.Again, be not in smoke shielding device engaging interval close the door before finishing close the door between the termination environment time, as long as the corresponding setting of carrying out torque limiter with this smoke shielding device engaging interval just can, can adapt with various smoke shielding devices.And in memory storage, do not store in advance smoke shielding device have or not information the time, also can make it after elevator is installed, have or not the detection of smoke shielding device, and obtain same effect as implementing form 2.
