The specific embodiment
[example 1]
Fig. 1 is the front view of safety device of the elevator of expression the invention process form.
Be provided with crossbeam 2 on the top of car 7, on this crossbeam 2, be provided with the guide rail 3 that door 1 usefulness of cage side is supported in switching freely.Again, the door 1 of cage side is fixed on door 1 with cage side on the suspension hook 4 that opens and closes Direction guide.Open on the upper portion of the belt of establishing 12 and the lower portion on even keel on drive wheel 11 and the flower wheel 13 and to fix suspension hook 4 respectively, utilize the both sides' of drive wheel 11 and flower wheel 13 rotation the door 1 of cage side to be opened and closed by belt 12.
Disposing actuating device 5 on the top of crossbeam 2.Actuating device 5 is by motor 6, with the fixing coaxially drive wheel 8 of the output shaft of motor 6, hang over the belt 9 on the drive wheel 8, to flower wheel 10 transmission of drive force of rotating the front that is fixed on crossbeam 2 freely.Drive wheel 11 so motor 6 transmits propulsive effort, move mutually by the suspension hook 4 that is fixed on the belt 12 with being toward or away to belt 12, carries out the switching of the door 1 of cage side owing to be fixed coaxially with flower wheel 10.Therefore, drive wheel 11 and flower wheel 13 are configured in the positive roughly the same height of crossbeam 2 and are configured in the position that enough separates so that the door 1 of cage side can carry out on-off action.
The side of working with door 1 the action of cage side, passenger's turnover car detected door 1 usefulness, that be installed in cage side as the light projector 14 and the light-receiving device 15 of electrooptical device.Light projector 14 is configured under door 1 state of opening of cage side door 1 the approaching position, side with cage side in car 7, light is exported.Light-receiving device 15 also is provided under door 1 state of opening of cage side door 1 the approaching position, side with cage side in car 7, the light from light projector 14 outputs is detected.
Fig. 2 is the birds-eye view of safety device of the elevator of expression the invention process form 1.Work becomes: with the door 1 of the cage side of Fig. 2 as separate, upside is cage side, has the downside of the door 17 of waiting hall side to become waiting hall side.Light from light projector 14 outputs, inject from become vertical side with door 1 the moving direction of cage side in left side Fig. 2, door 1 by cage side, and by with the relative face in side of door 1 the incident of cage side, in case after penetrating to the atmosphere, the door 1 of cage side is to the right injected and is similarly penetrated and arrive light-receiving device 15 from its relative face once more.Therefore, the position that sets light projector 14 and light-receiving device 15 is naturally outside the movable range of the door 1 of cage side, owing to be configured near the framework of car 7, so even the door 17 of the door 1 of cage side and waiting hall side uses the occasion of the material of light transmission on the whole, electrooptical device also be can't see at showy place, so can improve the design-calculated degree of freedom.
The electrooptical device that constitutes by light projector 14 and light-receiving device 15, the passenger crosses the light of light projector 14 outputs when door 1 the closing movement of cage side, can not when light-receiving device 15 is injected, this information be passed to controlling device for doors 16 at light, controlling device for doors 16 oppositely moves the door 1 of cage side or stops, and the door 1 that the door 1 of cage side is controlled to cage side can not collide the passenger.Again, the door 1 of cage side has when opening and closing door 17 engagement sections of moving integratedly 18 with the waiting hall side of each layer of elevator, and door 17 sides of waiting hall side also have engage with this engagement section 18 and with 1 portion that is stuck 19 of moving integratedly of cage side.In addition, describe in detail in the back for controlling device for doors 16.
Again, the frame of broken lines of Fig. 2 is door 17 the position of the waiting hall side of elevator in the past, the present invention is because light path is positioned at the scope of door 1 the thickness of cage side, so compare with the situation of door between 17 of waiting hall side with the door 1 that light path was configured in cage side in the past, do not need to leave the part in the space of this light path, the door 1 that can make cage side reduces with door 17 the gap of waiting hall side, the door 17 of waiting hall side can be configured in the past in the space of guaranteeing as light path.
The door 1 of cage side is at least for the material that need adopt printing opacity by the part of this light.Concrete example as this material can be a glass, also can be the plastics of light-transmission type.Again, though for by the part beyond the light since take precautions against to go up or design on reason make the occasion of transparent configuration, also the door 1 of cage side integrally can be made glass or adopt reinforced plastic.Usually, because light has rectilinearity, so light projector 14 and light-receiving device 15 in the scope of 1 thickness of cage side, further are configured in the position of opening direction point-blank with respect to the on-off action scope.But, may not set the translucent material by light, the occasion of material point-blank, owing to light only passes through, so but form light path with regard to curve ground by the optical fiber in the door 1 of curve ground formation cage side in optical fiber as optical fiber.
In addition, the part of passing through at door this light at least of 1 of cage side uses the material of light transmission, do not use the occasion of material of the light transmission of glass etc. for other part, even the light visible rays of light projector 14 outputs is also seldom influential to design aspect.But, in the occasion that door 1 integral body of cage side is made glass or reinforced plastic, when the light of light projector 14 outputs is made as visible rays, except the occasion that this light is used as a kind of design, can be influential to design aspect, so need to use and frequency field that how many frequency limits of infrared ray etc., visible rays staggers.
Controlling device for doors 16 is elaborated.Fig. 3 is the constructional drawing of the controlling device for doors 16 of the safety device of elevator in the expression the invention process form 1.
Controlling device for doors 16, input carry out the management of the operation conditions of door, the control of motor 6 from the output signal of light-receiving device 15 and the signal of motor position detecting device 20.
At first, the output signal of light-receiving device 15 is imported to signal processor unit 22 through the input/output unit 21 in the controlling device for doors 16.Again, the position detecting device 20 that the position of the output shaft of motor 6 is detected utilizes door position detecting devices 23 in the controlling device for doors 16 to be transformed into the position of the door 1 of cage side.For example, position detecting device 20 is coders, the output of this coder be the occasion of impulse singla, according to this impulse singla, door position detecting device 23 carries out the addition of impulse singla or subtraction etc., is converted into the position of door.And, the output of door position detecting device 23 is imported to signal processor unit 22.
Signal processor unit 22 is according to from exterior requirement, according to the device of from the output of the output of input/output unit 21 and door position detecting device 23 motor 6 being controlled and the position of the door 1 of cage side being controlled.At this moment, also can from store signal processing sequence that motor 6 is moved, when the position of the door 1 of cage side is controlled motor 6 condition and make cage side door 1 load that moves etc., be fit to memory storage 24 acquired informations of the information of operating environment.In addition, also can obtain the information that optimal control is used of carrying out of being accumulated from the recording device 25 of the variable quantity that write down the time dependent controlled variable that makes the load that motor 6 moves etc.According to these information, signal processor unit 22 is exported the output signal of the best to motor 6.
The output signal of signal processor unit 22 is to output transform device 26 input, carries out predetermined process and to output-controlling device 27 outputs.For example, output unit 28 usefulness transistors (FET or IGBT etc.) carry out the occasion of PWM (Pulse Width Modulation) control, are altered to and the corresponding pulse of the ratio with respect to peak output from the output signal of signal processor unit 22.The ratio of the relative driving frequency of this pulse width is with roughly the same with respect to the ratio of peak output from the output signal of signal processor unit 22.
To import to output-controlling device 27 from the pulse of output transform device 26 outputs, be controlled to the output that is suitable for output unit 28, the line output of going forward side by side.For example, in above-mentioned same occasion, the magnitude of voltage of being imported is amplified etc., making becomes the voltage that is suitable for most to as the transistorized grid input of output unit 28, the line output of going forward side by side.And, according to the output of output-controlling device 27, by giving required current potential and motor 6 is controlled to motor 6 from power supply 33.
Principle of work is described.
According to from exterior requirement, the signal processor unit 22 in the controlling device for doors 16 are given output unit 28 by output transform device 26, output-controlling device 27 with required signal, and in view of the above motor 6 are controlled.When making the output shaft anti-clockwise rotation of motor 6 among Fig. 1, drive wheel 8, belt 9, flower wheel 10, drive wheel 11, belt 12, flower wheel 13 be anti-clockwise rotation all.So, because the suspension hook 4 that is fixed on the belt 12 moves to the direction that is separated from each other, so be fixed with 1 the moving of cage side of suspension hook 4 to the direction of opening.Again, when the signal processor unit in the controlling device for doors 16 22 is controlled and make the output shaft right-hand revolution of motor 6, because drive wheel 8, belt 9, flower wheel 10, drive wheel 11, belt 12, flower wheel 13 be right-hand revolution all, so be fixed on belt hook 4 specifically and move to direction adjacent to each other, the door of cage side 1 moves to the direction of closing.When they move, the position of the position detecting device 20 that detects according to position of rotation to the output shaft of motor 6, the position of door position detecting device 23 opposite houses detects the position of opposite house to control.
When above-mentioned action, in the electrooptical device that constitutes by light projector 14 and light-receiving device 15, utilize the instruction of signal processor unit 22, light projector 14 output light, the signal of the light that light-receiving device 15 these light of reception and process input/output unit 21 will receive sends to signal processor unit 22.And light-receiving device 15 will not be sent by the signal of light will, when signal processor unit 22 transmits, and the instruction that signal processor unit 22 for example stops output shaft to motor 6 outputs.Receive light-receiving device 15 at signal processor unit 22 and be not subjected to light to instruct the occasion of this signal, except above-mentioned, also can carry out various controls.For example, 1 carry out the occasion of closing movement at the door that makes cage side, when receiving this signal, the rotation of motor 6 is stopped, also can carry out the control of opening action on the contrary.
As mentioned above, the present invention, dispose light projector 14 and light-receiving device 15 respectively in the both sides of gangway by door 1 elevator that opens and closes of cage side, to the passenger by the gangway wait 32 existence to detect and the safety device of elevator that the on-off action of the door 1 of cage side is controlled in, by the light transmission member form cage side the door 1 all or part of, and, with the end face portion of this light transmission member light projector 14 and light-receiving device 15 are set relatively, owing to form from light projector 14 to light-receiving device 15 light path through the inside of light transmission member, the position that so electrooptical device can be configured in cage and take advantage of the Room not see, can obtain to reduce to dispose the electrooptical device that constitutes by light projector 14 and light-receiving device 15 cage side door 1 and waiting hall side 17 between the elevator in gap.
In addition, owing in the door 1 of cage side, be filled with the material of light transmission, also has the effect that the intensity of the door 1 of the cage side of preventing reduces by the part of light.
Also can obtain the effect same will being configured in occasion on door 1 the side end surface of cage side with example 1 by the electrooptical device that light projector 14 and light-receiving device 15 constitute again.Again, the electrooptical device that constitutes by light projector 14 and light-receiving device 15 in door 17 the side end surface or the side configuration of waiting hall side, and each layer gone up the occasion that passenger between the door 17 of waiting hall side etc. detects, the door 17 of waiting hall side, if form from light projector 14 to light-receiving device 15 light path at least through the inside of light transmission member, just can and example 1 similarly to waiting hall side 17 between passenger etc. detect.
[example 2]
Example 2 is the forms of degree of freedom that can improve the configuration of the electrooptical device in the example 1.
Fig. 4 is the door 1 of cage side of safety device of elevator of expression the invention process form 2 and the layout circle of electrooptical device.In addition, identical for the part of not expression with example 1, the symbolic representation identical or cooresponding part identical among Fig. 4 with Fig. 1.
To describing with not existing together of example 1.
As shown in Figure 4, owing to do not dispose light-receiving device 15 on the output direction of light of light projector 14, words light-receiving device 15 like this can not receive the light of light projector 14 outputs.But the reflecting body 29 that the light of reflected light electric installation is such is imbedded in the door 1 of cage side of light projector 14 sides, just can inject to light-receiving device 15 from the light of light projector 14 projections by suitable setting angle of reflection.Thus, utilize electrooptical device that the passenger is detected required height with regard to not needing light projector 14 is configured in, because the height of configurable light projector 14 can freely be selected, so in the occasion that electrooptical device can't be installed because of miscellaneous equipment etc., just the position of light projector 14 can be configured with staggering.
As mentioned above, in this example 2, not only play the effect same, and the door 1 by cage side has reflecting body 29 and can improve the degree of freedom that electrooptical device disposes on door with example 1.
In addition, in this example 2, though reflecting body 29 is embedded in light projector 14 sides cage side the door 1 in, also reflecting body 29 can be arranged on light-receiving device 15 sides cage side the door 1 in.And can also be more than 2 with reflecting body 29 configurations, in the door 1 of the cage side of light projector 14 sides and in the door of light-receiving device 15, respectively dispose 1, if change the angle of reflection the track of light is made suitable structure, also the top or the bottom of the door 1 that the light projector 14 and the light-receiving device 15 of electrooptical device can be configured in cage side.
Again, the occasion that detects in the hoist trunk side that electrooptical device is configured in elevator, to the passenger of door between 17 by waiting hall side, the door 17 of waiting hall side has the light transmission member in the part that constitutes optical axis at least, by seeing through the light of light projector 14 outputs, just can similarly detect the passenger between the door 17 of waiting hall side.
[example 3]
Example 3, the light projector that is example 1 and 2 be also to the fore-and-aft direction output light of the door of the door of waiting hall side and cage side, and the form that the light of the light projector output reflected light after by reflections such as passengers is received.
Fig. 5 is the birds-eye view of safety device of the elevator of expression the invention process form 3.In addition, identical for the part of not expression with example 1, the symbolic representation identical or cooresponding part identical among Fig. 5 with Fig. 1.
Do not describe not existing together with example 1.
For the electrooptical device in the example 1, the light of light projector 14 outputs is in the scope of the thickness of the door 17 of the door 1 of cage side or waiting hall side, but the light projector 30 of the electrooptical device in this example 3, light by will having angle is also exported light to the horizontal direction output of car 7 at the fore-and-aft direction of the door 1 of the door 17 of waiting hall side and cage side, this light-receiving device 31 is detected by 32 backward waves that cause such as passengers by the light of exporting from light projector 30 and passenger is waited 32 have or not and detect, and can more correctly wait 32 to detect to passenger, and can improve safety.
If invention in the past because between the door 17 of the door 1 of cage side and waiting hall side, the front that is installed in, so exist in the problem that this part need be provided with the gap.
Again, the door 1 of cage side and the door 17 of waiting hall side are making the occasion of translucent material, and this electrooptical device becomes and can see, has bad in appearance problem.
And in this example 3, light projector 30 outputs have the light of the angular range of regulation.Because the angular range of this light, so a part by the translucent material part, is advanced to 17 fore-and-aft direction of the door 1 of cage side and waiting hall side with regulation.So, and collide and reflected light the door 1 of cage side and near the passenger of door 17 of waiting hall side etc. 32.This backward wave door 17 translucent material part of the door 1 by cage side and waiting hall side is once more injected and can be accepted light to light-receiving device 31.Although the refraction that partly causes because of atmosphere and translucent material can take place, the door 1 that passes through cage side of light projector 30 and wait 32 to collide with the passenger after backward wave to be detected by light-receiving device 31 be not in-problem.
But, from the light of light projector 30, formerly with the floor of taking advantage of the Room in door 17 the outside that is located at waiting hall side be not the occasion of the collisions such as outer wall of translucent material, this reflected light can not arrive light-receiving device 31.Therefore, the light that produces at the angular range of the light that utilizes light projector 30 output passes through must not exist in the scope outer wall of taking advantage of floor, the Room etc.Thus, the angular range of the light of light projector 30 output decides according to the position relation of light projector 30 and the outer wall of taking advantage of floor, the Room etc.
As mentioned above, in this example 3, owing to light projector 30 output faces can receive the reflected light that is reflected to collisions such as the light of the fore-and-aft direction of door and passengers simultaneously to the light of the side surface part of light transmission member with towards light, the light-receiving device 31 of the fore-and-aft direction of door, thus can obtain big passenger detection range, and can obtain to have improved the elevator of safety.
[example 4]
Example 4 be the material of controlling device for doors 16 door 17 that the sensitivity of the output of light projector and light-receiving device can be adjusted to the waiting hall side that is suitable on each layer and shape structure.
Sometimes the shape of elevator door 17 of waiting hall side in each layer, material etc. change, especially arrive the fore-and-aft direction of the door 17 of the door 1 of cage side and waiting hall side like that from the light of light projector 30 outputs at example 3, and light-receiving device 31 receives the catoptrical occasion from passenger etc., changes because of the influence of the shape of door, material etc. makes the combination of the sensitivity of every layer of output of going up light projector 30, light-receiving device 31.Therefore, this makes up might produce when inappropriate and waits 32 erroneous judgement other to passenger.In this example, electrooptical device is adjusted according to the shape of the door 17 of the waiting hall side of each layer etc.
The structure of this example is identical with example 3.Fig. 6 is a diagram of circuit of the electrooptical device of the safety device of the elevator of the invention process form 4 being adjusted usefulness.
Principle of work is described.
At first, which layer car 7 is stopped at and detect (S1).The signal processor unit 22 of the detection information of each layer in controlling device for doors 16 transmits with this.
Then, signal processor unit 22, according to each layer detection information, carry out access and obtain its information (S2) to the memory storage 24 of the sensitivity information of the output information of the corresponding suitable light projector 30 of the thickness that stores on each layer and the glass material that has that it's too late glass material in advance and shape and light-receiving device 31.And, adjust (S3) according to the output of this information, 22 pairs of light projectors 30 of signal processor unit, the sensitivity of light-receiving device 31 is regulated (S4).
As mentioned above, in this example 4, since have according to the material of the door of each layer and shape different, can make light change such light projector 30 and can be to the light-receiving device 31 that revised by luminous sensitivity, so can obtain further to improve the elevator of safety.
In addition, in this example, the situation that the both sides of light projector 30 and light-receiving device 31 are adjusted is described, but also can carry out folk prescription respectively.Again, electrooptical device is described for the situation of example 3, and the situation of example 1 and 2 for the path of light and material, because of each layer different sometimes, so this occasion has same effect by the structure of using this example.
