Description

Variable speed type passenger conveyor

The present invention relates to variable speed type passenger conveyor, particularly relate to and allow the passenger take the variable speed type passenger conveyor that on the variable-ratio seat board, transports.

The passenger conveyors overwhelming majority's that replacement passenger horizontal direction moves scheme is to adopt the variable-ratio mode, this mode is when fed distance is longer, because of the shifting time lengthening, thus the speed of pars intermedia accelerated, and need relatively slow down the speed of on-board and off-board end for the sake of security.

This variable speed type passenger conveyor can be divided into substantially the belt conveyer of changing to friction speed and roller mode, the seat board of taking the passenger is laterally slided and make the speed of direction of tilt make the mode of variable-ratio and make the seat board flexible mode that realizes variable-ratio etc. at interval.For example No. 1583906, visible French patent of invention of transfer manner and Japanese patent of invention disclose the 1994-156693 communique, laterally the open 1972-220 communique of the as seen for example Japanese patent of invention of sliding type.

Make the flexible at interval mode of seat board also have multiple, in addition, Japanese patent of invention bulletin 1971-7057 communique and the open 1992-209191 communique of Japanese patent of invention disclose the mode that adopts pantograph linkage to make seat board interval scaling, the open 1975-78080 communique of Japanese patent of invention discloses and adopted the mode of the plank frame of the dilatation of seat board own, the open 1983-89579 communique of Japanese patent of invention to disclose the mode that the seat board lap stretches out.

Relevant handrail aspect, No. 1286453, Britain's patent of invention is disclosed to be handrail and seat board one design-calculated structure.

In addition, aspect the step passenger conveyors, adopted to make 3 block plates be level or 2 block plates are level and last block plate bevelled mode is taken the structure of area to guarantee wheelchair.

Below have a talk the present invention and want all problems of solving.

The 1st problem that the present invention wants to solve is in order to be fit to the weakling.

The variable speed type passenger conveyor purpose that is provided with as object of the present invention is, when growing apart from parallel motion, not only be fit to common pedestrian, and can alleviate the fatigue that the people etc. of heavy objects such as weakling such as wheelchair user, the elderly and suitcase moves.

Yet, in above-mentioned conventional art, adopt the transfer manner of belt to be not suitable for the wheelchair use, in addition, make modes such as seat board dilatation or lap stretch out also can in the needed scope of taking of wheelchair, cause the phenomenons such as distortion of seat board, can not consider aspect wheelchair, to use, and not meet the purpose that is provided with of the present invention.

Therefore, the present invention's the 1st purpose is, the seat board formula that can be fit to weakling, particularly wheelchair user variable speed type passenger conveyor is provided.

The present invention's the 1st purpose also is, is provided at wheelchair and takes the variable speed type passenger conveyor that the seat board integral type is moved.

The 2nd problem of the present invention is the problem that will solve the fixedly bottom surface at the interval that produces between the seat board.

The variable speed type passenger conveyor that transports on seat board for realizing allowing the passenger take needs the interval of seat board flexible.But this moment, in technology in the past, all seat boards all are front and back seat board bonded assemblys, the speed-adaptive that stretches by connecting portion changes, yet over-speed gear ratio is subjected to being contained in the interior pars contractilis length of seat board and the restriction of the length ratio of seat board own, so common over-speed gear ratio can only be in 2 times.

Therefore, for obtaining bigger over-speed gear ratio, just must make and produce gap (at interval) between the seat board.When using the variable speed type passenger conveyor that opens between the seat board at interval, normally following repeatedly action: seat board continuous down from last visitor's bottom surface (continuously every) occurs, become passenger's the portion of taking, this is enlarged at interval and quicken at pars intermedia, the interval between the seat board before and after down visitor's a end dwindles again, make the seat board contact, disappear at interval, enter down under the bottom surface at visitor place.Yet,,, will collide with the seat board that is several times as much as objective place speed, quite danger if the passenger is arranged or the thing be with falls in this interval when this seat board bottom surface between at interval fixedly the time.

About this point, in No. 1286453, above-mentioned Britain's patent of invention, what take is to change to the seat board that high-revolving main conveyor uses to walk on conveyer, but considers the seat board problem at interval of overdriving.In addition, the speed change of the relative seat board of conveyer is the constant speed unmodified, so speed at interval can not be corresponding with seat board speed.

Therefore, the present invention's the 2nd purpose is, provides a kind of and seat board velocity variations to drive the device of seat board bottom surface spaced accordingly.

The present invention's the 2nd purpose also is, the variable speed type passenger conveyor that improves the safety of seat board bottom surface spaced is provided.

Below, referring to figs. 1 through Figure 20 an example of the present invention is described.

In order to realize variable speed type passenger conveyor, the present invention is integrant with the combination form of the multinomial invention that interrelates, so in the explanation of this example, explain accordingly mutually with this object of invention.

The variable speed type passenger conveyor structure and the configuration thereof of this example at first, are described referring to figs. 1 through Fig. 4.

Fig. 1 is the approximate three-dimensional map of expression linear pattern variable speed type passenger conveyor.

In the figure; 1 for taking the seat board that the passenger transports; the flat board that the 2 upward visitors that begin to take for the passenger locate; 3 begin the acceleration roller that the seat board 1 to pars intermedia quickens for visitor's a end from the variable speed type passenger conveyor that puts seat board 1; 4 carry the high speed conveyer of seat board 1 for what put seat board 1 at a high speed at pars intermedia; 5 begin the deceleration roller that the downward seat board 1 of visitor's a end slows down for what put seat board 1 from pars intermedia; 6 is the following objective flat board that the passenger walks out of from seat board 1; 7 is the seat board handrail; 8 is seat board handrail accommodation section; 9 is grill-protected, and 10 is the grill-protected Emergency Exit.

As shown in the figure, this linear pattern variable speed type passenger conveyor carries out following action repeatedly: seat board 1 occurs continuous below last visitor's flat board 2 (continuously every), become passenger's the portion of taking, this is enlarged at interval and quicken quickening interval with roller 3, between corresponding to the high velocity that accounts for the more than half high speed conveyer of passenger conveyors 4, move, dwindle the interval between the seat board of front and back with the interval of roller 5 in the deceleration of a following objective end, make the seat board contact, disappear at interval, enter down flat board 6 that the visitor locates below.Because therefore the variable spaced of this seat board can make the speed of the speed of pars intermedia greater than the on-board and off-board end.

Like this, in this example, in the bottom of seat board 1 owing to dispose high speed conveyer 4 that the acceleration quickened successively moves with roller 3, with certain speed and the deceleration usefulness roller 5 that slows down successively, so utilize friction force to make seat board 1 quicken with roller 3, high speed conveyer 4 and slow down to use above the roller 5 to move, thereby the passenger who takes on seat board 1 is moved at these.

At this, by quickening with roller 3, high speed conveyer 4 and slow down to constitute seat board septal surface actuating device with roller 5, simultaneously, constitute seat board actuating device with roller 3, the deceleration that is equivalent to the high speed conveyer 4 of seat board high-speed driving device and is equivalent to the seat board speed reduction gearing with roller 5 by the acceleration that is equivalent to the seat board acceleration device.The example of this example has adopted the structure of seat board actuating device and seat board septal surface actuating device dual-purpose.

Because seat board actuating device and seat board septal surface actuating device dual-purpose, utilize the friction of seat board and seat board septal surface actuating device to drive, therefore, can make the speed of seat board identical, make the speed synchronization of seat board and seat board septal surface with each locational speed of seat board septal surface actuating device.

Like this, when between seat board and the seat board before and after it, producing at interval along with velocity variations, this seat board septal surface still can be synchronous with seat board speed drive, even this moment has the passenger to stand on the seat board bottom surface spaced or passenger's object drops, can not collide yet, can guarantee the safety at interval of relevant seat board with great velocity contrast and seat board.That is to say that the seat board septal surface actuating device of this example has played the effect of the safety device of variable speed type passenger conveyor.

According to this example, because seat board actuating device and seat board septal surface actuating device dual-purpose, therefore can complicated mechanism and make the speed of seat board and seat board septal surface reach synchronous.

Again, according to this example, because seat board actuating device and seat board septal surface actuating device dual-purpose, but therefore simplified structure provides the variable speed type passenger conveyor that cost is reduced because of mechanism's dual-purpose.

Again,,, can not collide yet, can improve safety with great velocity contrast and seat board even when seat board interval standing passenger or passenger's object drops according to this example.

In order to take wheelchair, seat board 1 adopts polylith (this example is 3) bonded assembly structure.In taking passenger's scope, though along with the velocity variations of passenger conveyors is connecting be connected seat board between the meeting generation interval of seat board with other, but can not produce at interval owing to connect between the interior polylith seat board of seat board, therefore, take connecting wheelchair on the seat board during moving on the passenger conveyors, can not be subjected to influence at interval.

At this, the size of wheelchair can be variant because of the application engineering (manual/electric etc.) and the difference in environment for use or epoch thereof of wheelchair.Aim of the present invention is, makes seat board possess the size that can take wheelchair, and the requirement of its size is the length/width of guaranteeing to take the coventional type wheelchair in the wheelchair standard of regulations such as Japanese Industrial Standards.

According to this example, owing to possess the sufficient size that can take wheelchair, and can not occur at interval when on its seat board, producing velocity variations yet, therefore be well suited for being applied to wheelchair.

Again, according to this example owing to occur the seat board of horizontal (continuously every) continuously at last visitor place, therefore, even when the use wheelchair, still can do not stop entire machine and the situation of the overall efficiency that can not descend under take.

On seat board 1, be provided with seat board handrail 7, this seat board handrail 7 comes out from seat board handrail accommodation section 8 at last visitor place, enters seat board handrail accommodation section 8 at following visitor place.

In the side of passenger conveyors, have with passenger conveyors and general path make difference prevent the passenger inside and outside the passenger conveyors object contacts or passenger conveyors inside and outside the grill-protected 9 of dealing.On grill-protected 9, be provided with grill-protected Emergency Exit 10 at certain intervals.Grill-protected Emergency Exit 10 is closed by electric property usually the time, stops the back at passenger conveyors and removes electric property and close, and becomes the Emergency Exit at the middle part, passenger conveyors way of long distance.This grill-protected Emergency Exit 10 is gone to spacer portion downwards from seat board 1 when passenger conveyors stops, by walking out grill-protected Emergency Exit 10 between the seat board handrail 7.Therefore; in the belt armrest that in the unconverted passenger conveyors of speed in the past, adopts the Emergency Exit can not be set; but if adopt this example; by with the interval of 1 on seat board handrail 7, seat board, the fixing grill-protected 9 and 10 combinations of grill-protected Emergency Exit of side, just can form the path of using when urgent.

And; even just in time overlap at the interval of a certain grill-protected Emergency Exit 10 and can not use the time with seat board handrail 7; by grill-protected Emergency Exit 10 being arranged to the seat board between high velocity and the interval of next block plate correspondence position is not the relation of integral multiple, can utilize any 1 grill-protected Emergency Exit to walk out when passenger conveyors stops all the time.

Fig. 2 (a) is the birds-eye view of variable speed type passenger conveyor shown in Figure 1, and Fig. 2 (b) is the lateral plan of variable speed type passenger conveyor shown in Figure 1.

In the figure, 11 for depositing the side cover plate of passenger conveyor equipment, and 12 is extreme gear, and 13 for returning the conveyer of a side.In addition, same position is represented at the identical position of symbol all with shown in Figure 1 in the figure.

As shown in the figure, seat board 1 occurs continuous below last visitor's flat board 2 (continuously every), become passenger's the portion of taking, quicken at interval by quickening to enlarge it with roller 3, move between corresponding to the high velocity that accounts for the more than half high speed conveyer of passenger conveyors 4, the interval between the seat board before and after the deceleration of an objective end is down dwindled with the interval of roller 5 contacts seat board 1 again, disappear at interval, enter down flat board 6 that the visitor locates below.

The flat board 6 following seat boards 1 that enter down the visitor place turn round because of extreme gear 12, take and get back on the conveyer 13 that returns a side below the visitor place, by the revolution of extreme gear 12, expose from last visitor once more, carry out this circulation repeatedly.

As an example of speed this moment, the rate of onset of on-board and off-board place is 30-50m/ minute, and pars intermedia is its 2-4 times.Each length of an interval degree is different according to speed change ratio and acceleration-deceleration size, quickens to be about 5-10m with roller 3 and the interval of slowing down with roller 5, and the interval of high speed conveyer 4 is 100-2000m.The length of the high speed conveyer 4 of the centre of variable speed type passenger conveyor is longer than other length of an interval degree greatly, in the drawing of this example, be in order to illustrate that this example represents as an essential structural element, the ratio of its length etc. does not specially interruptedly partly amplify necessity or dwindles expression.In addition, to the usually used technology of passenger conveyors etc., omitted the key element of not having direct relation with the present invention.

Fig. 3 is the side sectional view of an objective end under the variable speed type passenger conveyor of this example.

In the figure, 14 are the control roller, 15-1 is a main motor, 15-2 is the control electrical motor, 16-1 is the high speed conveyer axle drive shaft that is driven by main motor 15-1,16-2 is the deceleration roller axle drive shaft of using roller chain drive-belt 17-2 transmission of drive force to slowing down that is driven by main motor 15-1,16-3 serve as reasons control with electrical motor 15-2 drive to the control axle drive shaft of control with roller chain drive-belt 17-3 transmission of drive force, 17-1 is the common drive chains for a plurality of decelerations usefulness of driving rollers 5 that driven by main motor 15-1,17-2 uses chain drive-belt for slowing down, what 17-3 served as reasons control usefulness electrical motor 15-2 driving is the control roller chain drive-belt of drive controlling with roller 14,18 are the acceleration and deceleration gear, 19 photoelectric sensing type position detectors near the detection seat board position the objective end under being positioned at, 19-1,19-2 is respectively down the illuminating part and the light accepting part of the position detector 12 that combination is provided with near the assigned position of an objective end.In addition, in the figure, represent same position with the position of same-sign shown in Figure 1.

Wherein, for realizing the present invention, on the position of regulation, disposed the position detector 12 of sufficient amount.

In the figure, seat board 1 utilizes friction force to use on the roller 5 in deceleration, drives along working direction, but skids owing to the friction force transmission produces sometimes, so also deceleration can be used the part of roller 5 as controlling with roller 14, in order to the correction to skidding.

The turning force of main motor 15-1 is transmitted to high speed conveyer axle drive shaft 16-1 by common drive chain 17-1, drives high speed conveyer 4.Again at the same time, the turning force of main motor 15-1 is transmitted with roller axle drive shaft 16-2 to slowing down by common drive chain 17-1 and acceleration and deceleration gear 18, drives with roller chain drive-belt 17-2 by deceleration and slows down with roller 5.At this moment, acceleration and deceleration are provided with the gear ratio at position with gear 18 according to it, and high speed conveyer 4 is carried out the speed change, so that quicken to use roller 5 relative each position with roller 3 with slowing down the different successively speed revolution of ratio according to the rules.Control is driven with roller chain drive-belt 17-3 with axle drive shaft 16-3 and control with electrical motor 15-2, control by control with roller 14, can with the independent respectively control of the speed of revolutions of main motor 15-1.In addition, the light that position detector 19 is sent by illuminating part 19-1 can reach cooresponding light accepting part 19-2 during no seat board 1 on its position, when seat board 1 is arranged because of crested, so can be from the position that is subjected to measure the light situation seat board 1 of light accepting part 19-2.

Because the variable speed type passenger conveyor direction of this example can be reversed freely, so can adopt visitor place and objective down place symmetrical structure.Otherwise, also can only electrical motor be set in a side, adopt unsymmetric structure, also can on a side of relative direction, be provided with to common drive chain 17-1 and apply the spring structure that tension force is used in case of necessity.

In the figure, 20 is guide rail, and 21 is the bottom surface.In addition, in the figure, same position is represented at the position of same-sign all and shown in Figure 3.

As shown in the figure, form on the surface of seat board 1 concavo-convex, with the comb teeth engagement on flat board 6 ends that are located at down visitor place, so when drop is arranged, also can pick up.

The passenger moves seat board handrail 7, side cover plate 11 and grill-protected 9 restrictions that are subjected on the seat board 1 at the transverse direction on the passenger conveyors.Yet, in this scope, also may stand in sometimes on the interval of seat board, therefore must make seat board septal surface actuating device, promptly quicken and slow down to reach the length of side cover plate 11 with the two ends of roller 5 width with roller 3, high speed conveyer 4.In addition, on seat board 1, owing to the wheel of taking thing and seat board own wt that supports on the seat board 1 need be set, so quicken to use the wheel interval of the width of roller 5 less than this seat board 1 with roller 3, high speed conveyer 4 and deceleration.

The device with roller 5 usefulness of drive slowing down is to be arranged within following seat board 1 width of seat board 1 with gear 18 with roller chain drive-belt 17-2 and acceleration and deceleration slowing down, slowing down, it is outside to arrive between the guide rail 20 of the vehicle that passes seat board 1 with roller axle drive shaft 16-2 and this wheel of supporting, and common drive chain 17-1 passes through the side arrival main motor 15-1 of wheel, guide rail 20 and not shown extreme gear 12.Otherwise the chain drive-belt 17-4 that returns the conveyer 13 of a side passes through to arrive within the seat board width main motor 15-1 in order not hinder seat board handrail 7.

In order to detect the position of seat board 1, the illuminating part 19-1 of position detector 19 and light accepting part 19-2 are set at this deceleration below in the wheel side cover plate 11 at interval of roller 5 and seat board and bottom surface 21.

Below, the control system of the variable speed type passenger conveyor of this example is described with reference to Fig. 5 to Figure 10.

Fig. 5 is the general block diagram of expression variable speed type passenger conveyor control system.

In the figure, 22 is control setup, and 23 is the electric voltage frequency control part, and 24 is starting switch, and 25 is halt switch, and 26 is anomaly detector, and 27 is anomaly alarming device.In addition, in the figure, same position is represented at the position of same-sign all and shown in Figure 3.

As shown in the figure, control setup 22 makes the 22-2 of portion by operation control section 22-1, speed command and the 22-3 of abnormality juding portion constitutes, accept the output of position detector 19, by operation control section 22-1 decision drive manner, make the 22-2 of portion by speed command and calculate speed command, provide speed command after calculating to electric voltage frequency control part 23.Electric voltage frequency control part 23 makes required voltage of main motor 15-1 and control motor 15-2 and/or frequency and output according to the speed command that provides.The main motor 15-1 that is subjected to this instruction drives high speed conveyer 4, extreme gear 12 and returns the conveyer 13 of a side, perhaps quicken to use roller 3 and slow down with gear 18 change speed rear drives with roller 5 by acceleration and deceleration, and by control electrical motor 15-2 drive controlling roller 14.

From the signal of starting switch 24, halt switch 25 or from the signal input control device 22 of anomaly detector 26, handle by 22-1 of motion control portion or the 22-3 of abnormality juding portion.Anomaly detector 26 comprises emergency stop switch 26-1, upward the visitor locates, the following objective flat board of locating is involved in detector 26-2, seat board handrail accommodation section is involved in detector 26-3, the side is involved in detector 26-4 and many kinds of devices of grill-protected Emergency Exit detector 26-5, also exports to anomaly alarming device 27 when unusual.

Below, the handler of the main program 100 in the control setup shown in Figure 5 22 is described according to diagram of circuit shown in Figure 6.

Owing to can realize following the processing by arithmetical device and software, particularly can under the situation of not having advance notice in advance, carry out processing such as its startup and insertion in case of necessity.In addition, below the main portion of Chu Liing is carried out by operation control section 22-1, and the operating speed instruction makes the 22-2 of portion during the decision speed command, detects and uses the abnormality juding 22-3 of portion when unusual.

At first, check the state of passenger conveyors with step 100-1.When being in " stopping " state at passenger conveyors, confirm starting switch 4, if starting switch 24 access failure still then continues to stop with step 100-2.After starting switch 24 is connected, carry out startup by branch 110 and handle.When the state of step 100-1 is " in the running ", confirm halt switch 25, if halt switch 25 access failure is still then carried out running usually by branch 120 and handled with step 100-3.After halt switch 24 is connected, stop to handle by branch 130 execution.When the state of step 100-1 is " unusually ", executed as described below the processing that abends, so from continuing the state of abending between convalescence unusually.Periodic cycle is carried out the processing by main program 100 execution.

Fig. 7 is the diagram of circuit of the handler handled of the startup of the step 110 in the presentation graphs 6.

The state that this startup processing is a passenger conveyors is " stopping ", after starting switch 4 is connected, is begun to start by main program 100.At first, using step 110-1 is " starting in the processing " with the Status Change of passenger conveyors.Secondly, confirm halt switch 25 with step 110-2, if halt switch 25 access failures, the abnormality detection before then branch 140 execution start is handled.It is step 110-3 when no abnormal that abnormality detection is handled 140 result, carries out running when starting with step 110-4.The speed command of using when being meant startup that turns round during so-called the startup is exported with electrical motor 15-2 to main motor 15-1 and control.After step 110-5 confirmed to start normal termination, using step 110-6 was " in the running " with the Status Change of passenger conveyors, finished to start and handled.When step 110-2 starting when connecting halt switch 25 under the treatment state, when having detected at step 110-3 when unusual or at step 110-5 when normal termination starts, just change the processing when unusual into.Ending immediately to start at step 110-7, cut off starting switch 24 at step 110-8, is " unusually " at step 110-9 with the Status Change of passenger conveyors, at step 110-10 anomaly alarming device 27 is informed unusually.The state-transition of passenger conveyors be " unusually " afterwards, carry out unusual affirmation and reparation by the supvr and the maintenance person of passenger conveyors according to its content.

Fig. 8 is the handler diagram of circuit that step 140 abnormality detection in the presentation graphs 7 is handled.

It is to confirm emergency stop switch 26-1 by step 140-1 that this abnormality detection is handled; flat board with visitor place, following visitor place in the step 140-2 affirmation is involved in detector 26-2; confirm that with step 140-3 seat board handrail accommodation section is involved in detector 26-3; confirm that with step 140-4 the side is involved in detector 26-4; confirm grill-protected Emergency Exit detector 26-5 with step 140-5; whole when no abnormal; by step 140-6 output " normally "; if be judged as among the above-mentioned steps 140-1-140-5 certain 1 have unusual after, by step 140-7 output " unusually ".The abnormality detection of contacting directly with grill-protected Emergency Exit 10 open and-shut modes is added among this abnormality detection handles, can improve safety.

Fig. 9 is the handler diagram of circuit that the step 120 in the presentation graphs 6 turns round and handles usually.

Usually during running, carry out abnormality detection with step 140 and handle, secondly, if having unusually in that step 120-1 is unconfirmed, the form that turns round when common at step 120-2 outputs to main motor 15-1 with normal speed command.Detect the seat board position by step 120-3 use location detector 19 again, step 120-4 makes the 22-2 of portion by speed command and calculates required control speed according to the seat board position, and the speed command after will being calculated by step 120-5 is exported with electrical motor 15-2 to control.After step 120-1 detects unusually, enter branch 130, execution stops to handle.

Figure 10 is the handler diagram of circuit that stops to handle of step 130 in the presentation graphs 6.

This stop to handle the maximum speed that is divided into when stopping usually slowly reduction of speed slowly stop to handle and promptly stop to handle two kinds when urgent.At first, at step 130-1 the Status Change of passenger conveyors is " in stopping to handle ".Secondly, whether confirm to form the reason that stops to handle because of caused by abnormal at step 130-2, carry out running when stopping with step 130-3 when no abnormal, running was meant to main motor 15-1 and control and exports the speed command of using when stopping with electrical motor 15-2 when what is called stopped.After step 130-4 confirms to stop finishing, cut off starting switch 24 with step 130-5, be " stopping " at step 130-6 with the Status Change of passenger conveyors, finish to start processing.After step 130-2 detects unusually, perhaps at step 130-4 when normal termination does not stop, change the processing when unusual into, end running immediately with step 130-7, step 130-8 cuts off starting switch 24, is " unusually " with step 130-9 with the Status Change of passenger conveyors, informs unusually with anomaly alarming device 27 at step 130-10.Like this, because unusual content is output to anomaly alarming device, even therefore when unusual, also be easy to investigate thoroughly and solve reason.

Below, illustrate that with reference to Figure 11 the step 140-4 side with abnormality detection is handled shown in Figure 8 is involved in the relevant side of detection safety device at interval.

In the figure, 28 for covering brush at interval.As shown in the figure, when seat board 1 at seat board septal surface actuating device, be when passing through above the high speed conveyer 4 (or quickening with roller 3, deceleration with roller 5), side in the passenger conveyors working direction, side cover plate 11 is blocked the top of seat board 1, but will inevitably produce the interval that equates with the seat board height at least between high speed conveyer 4 and side cover plate 11.Therefore, under the state of opening at interval in its side, in case there is passenger's object to fall into the seat board septal surface, it is inner and damage machine that this object just might be from the side falls into passenger conveyors at interval.

For this reason, in this example, as interval, side masking device, for example cover brush 28 by the interval that dense arrangement such as graphic tiny resin is formed brush and sac like, cover plate is taken the surface of high speed conveyer 4 for 11 times from the side, and its side is covered at interval.Covering at interval brush 28 can be free movable before and after seat board 1 working direction, and not hindering passing through of seat board 1, but covering brush 28 has resistance in the side of working direction at interval, a part that prevents drop or passenger's body enter the side at interval in.

When the thrust pressure of this side is covered the resistance of brush 28 greater than the interval, be involved in detector 26-4 by the side that is arranged on the addendum modification detection usefulness on the side and carry out abnormality detection.Detect unusual after, testing result is inserted into aforementioned abnormality detection handles among handling 140, passenger conveyors is promptly stopped.

Side at interval masking device is not limited to structure shown in Figure 11, in line with aim of the present invention, also can adopt elastic body, prevents that to elastomeric method drop from entering side structure such as at interval by seat board 1 with upper and lower.

Like this, can improve the safety at interval of relevant side according to this example.

Below, with reference to the seat board 1 of the full and clear explanation of Figure 12 to Figure 14 as the variable speed type passenger conveyor main components.

Figure 12 is the partial top view of seat board, and Figure 13 is the cutaway view of seat board, and Figure 14 is the partial side view of seat board.

In these figure, 1-1 is a seat board, 1-2 is a seat board surface comb teeth (part that solid line is represented), 1-3 is bottom end comb teeth (part that oblique line is represented), 1-4 is the strength member that is located on the seat board 1-1 back side, and 1-5 is a bonded assembly seat board pin between strength member 1-4 and the axletree, and 1-6 is a wheel, the 1-7 contact surface that to be seat board 1-1 contact with the roller surface comb teeth with high speed conveyer, 29 is the comb teeth of high speed conveyer and roller surface.In Figure 12, the part surface on the long and short dash line shown in the side is observed the shape on seat board 1-1 surface, and the part under the long and short dash line shown in the side represents to observe the form of seat board 1-1 bottom.In Figure 13 and Figure 14, the part shown in the long and short dash line left side represents to observe the form of seat board 1-1 side, the form that the part shown in long and short dash line the right represents to observe seat board 1-1 section.

At this, as an example, the size of base plate 1-1 is respectively, and the interval between the seat board handrail 7 about seat board is about 1200mm, and the length of 1 base plate working direction is about 400mm (being 1200mm after 3 connections), and the interval of comb teeth is about 2mm.Graphic seat board shape and above-mentioned out-of-size are just done an expression with inscape here, not according to actual size.

Seat board 1-1 is made of metal sheet, forms seat board surface comb teeth 1-2 on its surface, is fixed with seat board handrail 7 on seat board 1-1.

Though the length of the seat board 1-1 working direction that moves as one also is the size design according to wheelchair, for the ease of taking wheelchair, the size of being got for example couples together 3 block plate 1-1, makes length more than 1000mm.

As mentioned above,, do not adopt a bulk of seat board, and the structure that adopts the polylith seat board to fuse can suppress the increase of the unit seat board weight of variable speed type passenger conveyor thus according to this example.

Again, according to this example, the size of unit seat board and common passenger conveyors are equal, so can realize the sharing of part and production facilities, suppress productive costs.

In addition, as shown in figure 12, because the end that connects seat board 1-1 working direction be along with velocity variations can produce at interval, it is the part of the seat board combination that contacts with front and back, also be seat board 1-1 bottom with seat board septal surface actuating device bonded assembly part, so be provided with seat board end comb teeth 1-3.Seat board end comb teeth 1-3 moves in the groove of the comb teeth 29 of high speed conveyer and roller surface, and the seat board end comb teeth 1-3 that is connected seat board with another piece makes up mutually and constitutes.At this moment, the seat board end comb teeth 1-3 of seat board 1-1 bottom enters combination mutually in the space of another comb teeth 1-3 bottom, block plate end as shown in figure 13.The seat board end comb teeth 1-3 of seat board 1-1 top then be with the flat board 6 that is located at down visitor place on, the comb teeth that forms same row with seat board surface comb teeth 1-3 has an effect, can get up at the lip-deep object of seat board dropping.

Like this, according to this example, can improve seat board in conjunction with the time safety.

According to this example, passenger who stand between the seat board interval or the object that drops are got back on the seat board again.

At this, seat board end comb teeth 1-3 is fixed on the seat board 1-1 with bolt etc. with the sort ofly making as raw material as plastic resin etc. that common step-like passenger conveyors is used.Therefore, seat board end comb teeth 1-3 is easy to adopt the different color with metal seat board 1-1, shown in the oblique line portion of Figure 12, not only in the end that connects seat board 1-1 working direction, and on the side end of seat board, also install, seat board boundary portion in connecting seat board 1-1 is not then installed, and adopts above structure just the portion of taking can be trapped among in the square frame and shows, and this is equivalent at the last objective device that falls into of preventing when locating to take seat board 1-1.

As mentioned above, according to this example, the connection seat board 1-1 that one is moved has made clear and definite difference with being connected the position that produces the interval between the seat board 1-1, falls in the time of can preventing to take.

As shown in figure 13, owing to adopt the height of seat board end comb teeth 1-3 to be higher than the structure of seat board surface comb teeth 1-2 height, so can be used as the falling apparatus of taking on seat board 1-1 when mobile that prevents.Even this just can make to take at the wheelchair on the seat board, perambulator, goods and move on the comb teeth 1-2 of seat board surface with the object of the band wheel of hand barrow and large-scale suitcase and so on, also can stop, can prevent from advance to fall in seat board 101 septal surfaces because of ladder with seat board end comb teeth 1-3 formation.

As mentioned above, according to this example, can prevent effectively that passenger or object from falling in the interval that connects between the seat board 1-1.

In addition, to shown in Figure 14,, in case of necessity strength member 1-4 can be set, again seat board pin 1-5 can be set, wheel 1-6 is installed in the side in the bottom of seat board 1-1 as Figure 12.The seat board 1-1 that connects in the seat board interconnects respectively, the common axle that is installed in the wheel 1-6 on the seat board pin 1-5 that uses.Therefore, in the interval that the passenger of parallel motion takes, though can not produce at interval at the Connection Block intralamellar part, but in direction when counter-rotating, as shown in figure 14, axle that can wheel 1-6 is a center steering, effective length is above the connection seat board of 1000mm when taking even adopt, and the radius during revolution also can be limited in and the equal length of independent seat board.

Like this, according to this example, can limit the length of variable speed type passenger conveyor depth direction.

As shown in figure 12, in order to increase the length that connects seat board, when using roller 3 by acceleration and slowing down with roller 5, the speed of roller has very big difference in its front and back.Therefore, when quickening with roller 3 and slow down when utilizing the frictional force drives seat board, in case whole seat board 1-1 contacts the power with regard to no longer being caused by velocity contrast on working direction with roller with roller 5.For this reason, the seat board bottom install that contact surface 1-7 limits and roller between contact position.As shown in figure 13, seat board 1-1 and conveyer only contact at contact surface 1-7 with roller, and form contactless state in other parts because of the height of seat board pin 1-5, so only can accept propulsive effort at contact surface 1-7.

The area establishing method of contact surface 1-7 is the situation according to the roller diameter of contact and roller speed variation, make the N/R power that is subjected to from the velocity contrast of roller in the scope of the connecting portion endurance that connects seat board, and can obtain to drive the required sufficient power of seat board.

As mentioned above, according to this example, can be convenient to manufacturing, construction, installation and the maintenance thereof of variable speed type passenger conveyor.

Below, the another example of variable speed type passenger conveyor seat board actuating device is described with reference to Figure 15 to Figure 20.

Figure 15 drives the seat board actuating device lateral plan of seat board for acceleration and deceleration.

In the figure, 16-3 serve as reasons control with electrical motor 15-2 drive to the control axle drive shaft of control with belt 31 transmission of drive force, 16-4 is the acceleration belt drive axle to acceleration usefulness belt 30 transmission of drive force that is driven by main motor 15-1,17-5 is for quickening to use the belt drive chain, 17-6 is control belt drive chain, 30 for quickening to use belt, and 31 is to control to use belt, and 32 for being located at the belt attachment strap that quickens with in belt 30 and high-speed belt 4 intervals.In addition, in the figure, represent same position with the position of same-sign shown in Figure 3.

This seat board actuating device is that many belts with speed change successively substitute acceleration in the last example with roller 3 with slow down with roller 5.Wherein, will speed up respectively with roller 3, control with roller 14, quicken with roller axle drive shaft 16-2, quicken with roller chain drive-belt 17-2 and control with roller chain drive-belt 17-3 change be quicken with belt 30, control with belt 31, quicken to use belt drive chain 17-5 and control and use belt drive chain 17-6 with belt drive axle 16-4, acceleration.In addition, the action of each inscape has substituted the action of aforesaid inscape, applicable as before aforesaid explanation such as control method.

When if the roller diameter of driving belt is too big, the overlap joint member of belt attachment strap 32 and so on can be set also at the overlap of belt and belt, belt and high speed conveyer.

Figure 16 adopts the lateral plan of the seat board actuating device of high-speed chain engagement type seat board for high-speed driving.

In the figure, 1-8 is the chain junction surface that is located at seat board 1 bottom, and 33 is high-speed chain, and 34 is the high speed sprocket wheel.

In variable speed type passenger conveyor, account for the more than half high speed overall speed of its length and fix, in the certain seat board interval of maintenance, seat board 1 is moved.Therefore, as shown in the figure, between high velocity, be provided with the rotating high-speed chain 33 of passenger conveyors maximum speed.On shared high speed conveyer axle drive shaft 16-1, rotating together high-speed chain is set again, drives high-speed chain 33 with gear 34.

Seat board 1 makes high-speed chain 33 engage with chain junction surface 1-8 being driven acceleration area by the seat board acceleration device and during with 34 of gears, utilizing the curvature of high-speed chain with gear 34 by high-speed chain.Thus, seat board 1 is driven by high-speed chain 33 between high velocity.Terminal part between high velocity utilizes high-speed chain with the curvature of gear 34, with opposite action the releasing that engages of high-speed chain 33 and chain junction surface 1-8, seat board 1 is changed by the seat board speed reduction gearing and drives.

Though the diagram of not making also can be understood, even turn back to the part at visitor place, need only in this interval not pace of change in seat board direction counter-rotating or from visitor down, just can similarly be suitable for the driving of chain juncture.

For this reason, in the time of making the speed synchronization of seat board and seat board septal surface, adopt the driving roller and the high-speed chain modes such as gear 34 same diameter of high speed conveyer 4, just can make the circular velocity unanimity.Otherwise, by gear of intermediary on axle drive shaft, perhaps change high-speed chain with the diameter of gear 34, also can make the speed of seat board and seat board septal surface make that each is different.

Like this, according to this example,, just can independently set the speed of seat board and seat board septal surface by between high velocity, the seat board actuating device being separated with seat board septal surface actuating device.

Figure 17 adopts the seat board actuating device lateral plan that adopts chain between linear motor, high velocity for acceleration and deceleration are interval.

In the figure, 23 is the electric voltage frequency control part, and 35 is linear motor control device, and 36 is the primary winding of linear motor.In addition, in the figure, same position is represented at the position of same-sign all and shown in Figure 16.

As shown in the figure, from linear motor control device 35 by electric voltage frequency control part 23, to a plurality of first siding rings 36 service voltages and/or frequency arranged side by side between acceleration area and not shown deceleration area, so that the speed of seat board 1 becomes the value corresponding to the position.Constitute seat board acceleration device and seat board speed reduction gearing thus.

Figure 18 is a seat board actuating device cutaway view shown in Figure 17.

In the figure, 37 is the secondary conductor of linear motor.In addition, in the figure, same position is represented at the position of all and Figure 13 and same-sign shown in Figure 17.

As shown in the figure, the bottom, interval at the seat board handrail 7 of seat board 1 disposes seat board septal surface actuating device, is high speed conveyer or roller, so at its side configuration seat board acceleration device and seat board speed reduction gearing, be the first siding ring 36 of linear motor.On seat board 1 and positions first siding ring 36 subtends, secondary conductor 37 is housed.In addition, in the bottom of seat board side seat board high-speed driving device is housed also, is high-speed chain 33 and chain junction surface 1-8.

Certainly also can not use high-speed chain 33, and by linear direct motor drive seat board between the whole district.

According to this example,, just can independently set the speed of seat board and seat board septal surface by between the whole district, the seat board actuating device being separated with seat board septal surface actuating device.

Again, according to example owing to only linear motor is set in the acceleration and deceleration interval, between high velocity by chain drive, but the therefore cost of suppression equipment and engineering construction.

Below, the relation of seat board speed and seat board septal surface speed is described with reference to Figure 19.

The corresponding figure of seat board actuating device that Figure 19 (a) has illustrated for the example with Fig. 1 to Figure 14, the expression seat board speed synchronous form consistent with seat board septal surface speed.

Under synchronous form, because of seat board speed and seat board septal surface speed indifference, so, make seat board septal surface actuating device become a kind of safety device that falls that tackles even there is object to fall into also no problem of seat board septal surface from seat board.As tackling the mode that object falls into the seat board septal surface, the synchronous form of no speed difference is the highest mode of safety.Yet, if there is not the velocity contrast of seat board speed and seat board septal surface speed between high velocity, this will make the passenger stand on the seat board, or stand on the seat board septal surface, can both similarly be transferred, become very convenient in walking on the seat board or on the seat board septal surface.But on variable speed type passenger conveyor, be temporary by the seat board septal surface of the pars intermedia that quicken to produce, this zone disappears because of the deceleration of a time objective side.In case passenger's walking is crowded on this seat board septal surface, then when a down objective side seat board septal surface disappeared, the passenger did not just have the part of standing, and existed one and pressed the danger that ground falls down.

Therefore, for fear of such state of affairs, the velocity rate with the seat board speed shown in Figure 19 (b) and seat board septal surface speed is that the certain geometric ratio type and the velocity contrast of seat board speed shown in Figure 19 (c) and seat board septal surface speed are certain two kinds of forms of equal difference type.

Make seat board and seat board septal surface by Figure 19 (b) or Figure 19 (c) when mode moves, because of seat board speed fast, so concerning taking the passenger on seat board, just form a kind of seat board septal surface by the correspondingly heterodromous state of velocity contrast, its result, become and reverse walking equal interval on common passenger conveyors in the walking of seat board septal surface, made the passenger psychologically or because of forming the state that is difficult to walking physically than common walking weak effect.

Exist under the state of velocity contrast in seat board speed and seat board septal surface speed; even have the object of wheel with hand barrow and large-scale suitcase and so on because of protecting improper falling in the seat board septal surface even work as wheelchair, perambulator, the goods taken on seat board; also can be very easy to turn back on the seat board because of speed difference is pushed back.

At this, the velocity contrast of seat board speed and seat board septal surface speed must be less than the rate of onset of last visitor place seat board partly.This is the velocity contrast equal extent for influence that makes the pars intermedia velocity contrast and last visitor place part, to guarantee safety.

Like this, according to this example, can be psychologically and physically reduce the walking of passenger on passenger conveyors.

According to this example, passenger who stand between the seat board interval or the object that drops are turned back on the seat board again.

When seat board actuating device and seat board septal surface actuating device independently are set, to set the velocity contrast of seat board speed and seat board septal surface speed greater than the speed of seat board septal surface, this also is possible physically.Yet this setting is auxiliary to aforesaid walking, in order to promote walking, will increase the danger of objective oral area down, can't use in practicality.

Figure 20 is a friction-driven of utilizing roller, makes the section-drawing that produces actuating device one example of velocity contrast between the seat board septal surface actuating device in seat board acceleration device/seat board speed reduction gearing and the corresponding portion.

In the figure, 38 is seat board driving roller, and 39 is seat board septal surface driving roller.In addition, in the figure, same position is represented at the position of same-sign all and shown in Figure 4.

As shown in the figure, in this example, will speed up with roller 3 and slow down and use roller 38 and seat board septal surface to drive as seat board driving with roller 39 with two different-diameters with roller 5 used rollers.The contact surface 1-7 of seat board 1 is placed in advance with seat board drives on the position with roller 38 subtends, other parts do not drive with the seat board septal surface and contact with roller 39.In addition, the seat board septal surface is driven by the seat board septal surface and constitutes with roller 39.Drive with roller 38 and seat board septal surface driving roller 39 with same drive shaft seat board.Its result, drive with the rotating speed of roller 39 identical with roller 38 with the seat board septal surface because seat board drives, the circular velocity of roller becomes the ratio of each roller diameter, therefore, for example seat board is being driven when being set at 80mm and 60mm with the diameter of roller 38 and the driving of seat board septal surface respectively with the diameter of roller 39, seat board speed and seat board septal surface speed just can realize the friction speed of 4: 3 ratios.

Like this, according to this example,, therefore can reduce part number, simplified structure owing to can in dual-purpose seat board actuating device and seat board septal surface actuating device, realize velocity contrast.

In a form of present embodiment, be characterized in that the bottom surface is made of a plurality of rollers that adopt belt conveyer and speed to change successively.

Another characteristics are that the bottom surface is made of a plurality of belts that speed changes successively.

Another characteristics are that the speed of bottom surface and the difference of described seat board speed are located seat board speed partly less than last visitor.

To be bottom surfaces be made of a plurality of rollers that adopt belt conveyer and speed to change successively another characteristics, and each locational speed of roller is the speed after the seat board speed of each position is reduced according to certain ratio simultaneously.

Again, the velocity contrast that must stipulate slowly than the 2nd speed of seat board of the speed setting of the seat board septal surface in the seat board interval of moving with the 2nd speed.

Again, the velocity contrast of regulation is less than the 1st speed of seat board.
