Equally, also being provided with mechanical type door closing force at car door and produce mechanism, even if generation is trapped in car, the electrical drive power of motor disappears, child falls to hoistway without being pried open by car door.Further, it is provided with mechanical type enabling power at car door and produces mechanism, in order to also be able to keep standard-sized sheet when the driving force of motor disappears when standard-sized sheet or when only existing less driving force.
Fig. 3 is the synoptic diagram in the engaging gap of embodiments of the present invention 1.The car of elevator lifts in not shown hoistway, thus the car door card bite wing film 12 being installed on lift-cabin door board 1 shown in Fig. 3 moves in hoistway.On the other hand, stop roller 13 protrudes from hoistway.Therefore, when the car of elevator lifts, with the equipment of cage side especially car door card bite wing film 12 contacts time, will cause that both damage.
Therefore, under the door full-shut position when lifting, as shown in (a) of Fig. 3, it is necessary to carry out the adjustment of mechanical system, make the distance between car door card bite wing film 12 and stop roller 13 namely engage gap 22 and keep constant.If engaging gap 22 shorter, produce install time specification error and/or timeliness change cause change of shape, car door/stop door deformation etc. time, exist equipment damage probability increase shortcoming.
On the other hand, when opening the door, when car door and stop badge close, the quality of the quality of car door and stop door clashes.Therefore, enabling speed during engaging needs to be low speed.
If engaging gap is shorter, then can set the interval of shorter driven at low speed, from the angle of door opening and closing, there is the advantage shortening opening time.On the contrary, if engaging gap 22 longer, then produce install time specification error and/or timeliness change cause change of shape, car door/stop door deformation etc. time, have equipment damage probability reduce advantage.
Generally, the specification engaging gap 22 is the permission accuracy rating decision of the size according to its distance and the deviation considering each floor place.But, allowing precision more hour, the degree of difficulty of the installation exercise regulating the engaging gap 22 of car door and all floors of stop is more big.
When fully closed, car door card bite wing film 12 separates, with stop roller 13, the distance engaging gap 22.Further, when motor starts to open the door according to door open command, car door card bite wing film 12 moves along enabling direction, and car door card bite wing film 12 contacted with the stop roller 13 of stop door in the moment of distance moving engaging gap value along enabling direction.When detecting contact, car door card bite wing film 12 holds car door, and thus car door and stop door are driven with the state linked into an integrated entity.
It addition, car door card bite wing film 12 can also be utilize multiple fin clamping stop door stop roller 13 mode or by car door card bite wing film 12 is sandwiched the mode transmitting driving force between multiple roller.
It addition, the distance between car door card bite wing film is fixed when fully closed, but distance can also change together with on-off action.The engaging gap 22 of Fig. 3 illustrates the distance between car door card bite wing film 12 and the stop roller 13 of fully closed side but it also may be the distance between car door card bite wing film 12 and the stop roller 13 of standard-sized sheet side.Hereinafter the distance between the car door card bite wing film 12 of fully closed side and stop roller 13 is illustrated as engaging gap 22.
Fig. 4 is the structure chart starting the door engagement device before opening the door of embodiments of the present invention 1.In the diagram, represent the car door card bite wing film of fully closed side with label 12A, represent the car door card bite wing film of standard-sized sheet side with label 12B.
Wherein, the car door card bite wing film 12B of standard-sized sheet side includes being fixed in lift-cabin door board and mode that stop roller 13 is sandwiched by irremovable mode and the action along with car door card bite wing film 12A completely.In the former mode not moved, stop door is provided with hammer, the character utilizing machinery door closing force to act on all the time, when opening and closing, changes an opening and closing speed in the way of making the stop roller 13 of stop door contact all the time with car door card bite wing film 12A.On the other hand, in the mode sandwiched completely of the latter, unrelated with door opening and closing speed, after completing to sandwich, the connection of car door and stop door will not be untied.
As shown in Figure 4, the door after car stop layers starts under the full-shut position before opening the door, and door motor 9 makes to produce driving force in door closing force direction, with the enabling power that opposing causes because of car vibrations when forcing open the door and/or lift of passenger in car.Driving force passes to car door card bite wing film 12A by band grasping part 8.
Car door card bite wing film 12A with engage tab stops 23A at the lift-cabin door board 1A car door arranged and contact, thus make lift-cabin door board 1 generation close the door the driving force in direction.Car door engaging tab stops 23A both can be elastomer as rubber, it is also possible to be the rigid bodies such as bolt.
Generally, the electric door closing force of the corresponding driving force based on motor 9, mechanical type door closing force act on lift-cabin door board fully closed near, thus electrically the summation of door closing force+mechanical type door closing force becomes the resistance for above-mentioned enabling power.
When sending door open command from controlling device for doors 10, door motor 9 makes to produce driving force in enabling direction.Door motor 9 is by with 7 and with grasping part 8, the driving force in enabling direction passes to car door card bite wing film 12A.
Car door card bite wing film 12A carries out action along the sliding conductor 24 being used for towards the smooth and easy action in door opening and closing direction, and direction of action is defined as the enabling direction of door or direction of closing the door.When door motor 9 produces the driving force in enabling direction, only car door card bite wing film 12A is driven, lift-cabin door board 1 does not carry out action, until car door card bite wing film 12A or be installed on till the contact detecting 25 of car door card bite wing film 12A contacts with stop roller 13.
Fig. 5 is the structure chart of the door engagement device opened the door when engaging of embodiments of the present invention 1.When car door card bite wing film 12A contacts with stop roller 13 (that is, during engaging), the contact detecting 25 being installed on car door card bite wing film 12 detects the contact of the two.Wherein, contact detecting 25 can be switch or the sensor of mechanical type or electric.Illustrate the example of mechanical switch in figures 4 and 5.
When contact detecting 25 contacts with stop roller 13, the amount of movement according to contact detecting 25, the junction surface with car door card bite wing film 12A is rotated by bolt-lock portion 26 as central shaft.Further, by this rotation, the terminal part in bolt-lock portion 26 mechanically engages with the sticking department 27 being fixed in lift-cabin door board 1A and is integrally forming.Therefore, the driving force of the door motor 9 passing to car door card bite wing film 12A is applied to lift-cabin door board 1A via bolt-lock portion 26 and sticking department 27.Wherein, bolt-lock portion 26 and sticking department 27 are equivalent to a portion of bindiny mechanism.
Further, driving force is delivered to lift-cabin door board 1A, and thus driving force is also delivered to lift-cabin door board 1B.So, driving force passes to stop door-plate 14A and 14B by stop roller 13, thus realizing opening the door and closing the door.
In figures 4 and 5, car door engaging tab stops 23A, 23B are installed in the end of sticking department 27 or sliding conductor 24, but are not necessarily required in end, it is also possible to be arranged in lift-cabin door board 1A.Further, car door engaging tab stops 23B is set to lean on enabling side than the contact site of stop roller 13 with car door card bite wing film 12 all the time.
In the non-stop layers of car in stop floor and when have sent opening and closing instruction to door motor 9, stop roller 13 is not in the position contacted with contact detecting 25.Therefore, in this condition, car door card bite wing film 12A engages tab stops 23A with car door and contacts, and thus car door card bite wing film 12A and lift-cabin door board 1A connects, it is possible to only make car door opening and closing.
It addition, engage between car door card bite wing film 12A and the stop roller 13 when gap refers to fully closed, it is possible to represent with following formula (1).
Engaging gap X=gap reference distance (X0) ± degree of regulation (Y) ... (1)
Wherein, degree of regulation (Y) typically requires the adjustment carrying out millimeter unit, the size according to its acceptable precision, and the adjustment difficulty of installation exercise increases.
Engaging gap has when car lifts and makes the car door equipment around clamping close device and the discontiguous effect of landing door equipment.Therefore, when car door opening and closing, after the distance moving engaging gap value, car door is connected by clamping close device (car door card bite wing film 12+ stop roller 13) with stop door, transmits drive force to the stop door not having driving device.
Generally, the relation of following formula (2) is set up for the quality of door-plate 1 and car door card bite wing film 12.
Lift-cabin door board quality × stop door-plate (containing roller) quality > > car door card bite wing film quality
……(2)
Lift-cabin door board 1 and stop door-plate 14 enter in the visual field of passenger, should avoid producing vibration.Wherein, when lift-cabin door board 1 and stop door-plate 14 conflict, according to the law of conservation of momentum, the two is subject to the bigger counteracting force corresponding with the quality of conflict side.Therefore, the door-plate causing at least one party produces the result of vibration.
On the other hand, when conflicting with stop door-plate 14 much smaller than the car door card bite wing film 12 of door-plate quality, act on the counteracting force of stop door-plate in the visual field entering passenger less.Therefore, it is nearly free from because of the vibration of the stop door-plate 14 caused that conflicts.
In this case, bigger reaction force acts is in car door card bite wing film 12 side.But, car door card bite wing film 12 has the following two feature different from door-plate.
(feature 1) car door card bite wing film 12, between lift-cabin door board 1 and stop door-plate 14, will not enter in the visual field of passenger.
(feature 2) is it addition, car door card bite wing film 12 and band grasping part 8 are rigidly connected, it is easy to realize controlling based on the speed/positional of motor 9.
Fig. 6 is an illustration for the figure of the reducing effect of the door vibration of embodiments of the present invention 1.Specifically, (a) of the Fig. 6 in left side illustrates that the vibration of prior art produces situation, and (b) of the Fig. 6 on right side illustrates that the vibration of the present invention reduces situation.Further, (b) of (a) of Fig. 6, Fig. 6 is the speed responsive that upper strata illustrates car door, and lower floor illustrates the speed responsive of stop door.
Conventional mechanism is before car door card bite wing film 12 and stop roller 13 is about to engage, and car door card bite wing film 12 engages with lift-cabin door board 1, and now as shown in (a) of Fig. 6, conflict during owing to engaging, the door-plate generation door at least one party vibrates.
On the other hand, the mechanism of the present invention is when car door card bite wing film 12 conflicts with stop roller 13, as shown in (b) of Fig. 6, it is possible to suppress door-plate vibration.
It addition, enter from outward appearance angle, lift-cabin door board 1 and stop door-plate 14 in the visual field of passenger, thus Complete Synchronization ground opening and closing both during preferably in opening and closing.As conventional mechanism, lift-cabin door board 1 conflicts with stop door-plate 14 and means that car door will drive in advance before stop door drives.Therefore, in conventional mechanism, although after engaging, both synchronize, but can not say both Complete Synchronizations in the whole region of switch motion.
On the other hand, in the mechanism with the present invention of structure of Fig. 4, Fig. 5, the driving force utilizing motor 9 after car stop layers only drives car door card bite wing film 12A only to move the amount in engaging gap 22, it is possible to realize the synchronization action completely of lift-cabin door board 1 and stop door-plate 14 in the whole region of switch motion.
About the effect of Complete Synchronization, except appearance, it is also possible to enumerate the effect that opening/closing time shortens for passenger.The opening/closing time of controlling device for doors 10 refers to that switching opening and closing instruction carrys out the time of drive motor 9.On the other hand, the opening/closing time for passenger refers to that car door carries out the time of action in the visual field of passenger.
Therefore, in the former case, the displacement of lift-cabin door board=engaging clearance distance+stop door-plate displacement,
And in the latter case, the displacement of lift-cabin door board=stop door-plate displacement.
Generally, just start in the interval, engaging gap after opening the door after car stop layers, it is necessary to do one's utmost the enabling speed that slows down, in order to reduce the sound and reduce above-mentioned counteracting force of conflicting of car door and stop door.Its main cause is to consider from the angle shortening door opening/closing time, it is impossible to set the gap reference distance X0 and degree of regulation Y in bigger engaging gap.
And in the structure shown in Fig. 4, Fig. 5 of the present invention, the quality of car door card bite wing film 12A is minimum relative to door-plate 14, thus it also is able to be set as there is the enabling speed being set to restriction at a slow speed in engaging interval, gap in the past faster.
But, in order to avoid producing conflict sound, it is preferable that the structure of car door card bite wing film 12A to be set to the quality of irreducible minimum.Further, by adopting the structure of the present invention, it is possible to the gap reference distance X0 in engaging gap and degree of regulation Y is set greater than in the past.As a result of which it is, degree of regulation can be relaxed.
It addition, the structure according to present embodiment 1, when contact detecting 25 is electric switch or sensor, it is possible to send detection signal to controlling device for doors 10.Further, in this case, controlling device for doors 10 can calculate motor from after starting to open the door to time of the card conjunction.
As a result of which it is, can in controlling device for doors 10 distance in the engaging gap 22 that rotation amount identification according to motor 9 is different because of each floor.Therefore, usual maintainer can use controlling device for doors 10 to carry out the confirmation checking the engaging gap 22 measured by visualization quantitatively, has the effect reducing maintenance burden.
