Specific embodiment

[first embodiment]

Hereinafter, the embodiment of passenger conveying appliance of the present invention and its control method is said based on attached drawing It is bright.Fig. 1 is the schematic structural diagram of the escalator of the typical example as passenger conveying appliance.As shown in Figure 1, escalator (multiplies Objective conveying device) 1 have：The truss 14 being erected between upper strata floor 12 and lower floor's floor 13；Configuration is led in the truss 14 It crosses step chains (not shown) and links for ring-type and carried out between stopping port 12a, 13a multiple steps 15 of loopy moving； The railing 16 of setting is erect along the direction of advance of these steps 15；It is supported by the railing 16, and progress synchronous with step 15 The mobile handrail 2 of loopy moving；For step 15 to be made to carry out the motor (driving device) 10 of loopy moving；And to motor 10 into The control unit 6 of row control.

Step chains rotate drive sprocket wound on drive sprocket (not shown) and by movable sprocket by motor 10, so as to Multiple steps 15 carry out loopy moving.At this point, mobile handrail 2 is also synchronous with step 15 to carry out loopy moving.In addition, railing 16 Lower part is covered by cover board 19, and the notch for entering mobile handrail 2 is provided in cover board 19.The notch is for making movement The inlet port 17,18 that handrail 2 enters.In addition, escalator shown in FIG. 1 is operated to up direction (A directions in figure).

In the present embodiment, the inlet port 17 that is set to 12 side of upper strata floor and be set to 13 side of lower floor's floor into At entrance 18, it is separately installed with the safety device for preventing from sandwiching foreign matter, hand.For being arranged on the safety device of inlet port 17 Each element, enclose a at the end of symbol, each element of the safety device for being arranged on inlet port 18, at the end of symbol B is enclosed, is distinguish with this, but safety device 20a is identical with the structure of safety device 20b, therefore the following description is main Safety device 20a is illustrated, omits the explanation to safety device 20b.

Then, the details of safety device 20a is illustrated with reference to attached drawing.Fig. 2 is to show to be arranged on upper strata floor The figure of the details of the inlet port of the mobile handrail of side.As shown in Fig. 2, safety device 20a has：It is arranged on inlet port 17 The position of inner portions, the moving direction (the A directions of Fig. 2) that can move along handrail 2 carry out the protective of mobile (displacement) 3a；For sensing the displacement sensor 4a of the amount of movement of protective 3a (displacement)；And the bearing of bearing displacement sensor 4a Part 5a.In addition, protective 3a is for example made of rubber, but there is no restriction for its material.

Protective 3a is mounted in inlet port 17 so that it is not contacted when escalator 1 runs well with mobile handrail 2, But if protective 3a is made to contact with mobile handrail 2 due to certain undesirable conditions, protective 3a moved handrail 2 draw and to The B directions of Fig. 2 are subjected to displacement.The state that protective 3a is in initial position by displacement sensor 4a does not connect with mobile handrail 2 Tactile state is set as zero shift and detects the displacement of protective 3a always, and exports detection data to control unit 6.Then, as rear As stating, relation pair escalator 1 of the control unit 6 based on the output valve from displacement sensor 4a and each threshold value D, E carries out Control so that reported as defined in carrying out or make 10 emergent stopping of motor.

Fig. 3 is the block diagram for the electrical structure for showing escalator.Information from safety device 20a (comes from displacement sensing The detection signal of device 4a, 4b) it is output to external i.e. monitoring room 11, the monitor in monitoring room 11 via control unit 6 and shows respectively Kind information.Administrator carries out the management of escalator 1 while various information are looked at.Control unit 6 has signal section 7, storage Portion 8 and operational part 9.Signal section 7 has following function, that is, by the displacement of the protective 3a detected by displacement sensor 4a Output valve and output time storage certain time, storage part 8 has following function, that is, storage and clamp hand sandwich foreign matter in this way Each detection pattern is corresponding, each threshold value of output valve and output time, operational part 9 has following function, that is, will be by signal section The output valve and output time of the sensor of 7 detections are compared with each threshold value being recorded in storage part 8, based on comparative result Motor 10 is controlled, so as to stop escalator 1 or produce the abnormal meaning to the report of monitoring room 11.

Fig. 4 is the figure for an example for representing the output valve (output quantity) from sensor.In Fig. 4, output valve C is represented by believing The output valve from displacement sensor 4a, 4b that number portion 7 is detected, threshold value D, E represents to be set in advance in respectively defeated in storage part 8 Go out the threshold value of value.In addition, threshold value E is equivalent to " first threshold " of the present invention, threshold value D is equivalent to " second threshold " of the present invention.

The relationship of output valve and output time when Fig. 4 (a) shows normal.It is passed by what signal section 7 detected from displacement The output valve C of sensor 4a, 4b are both no more than threshold value D, and also no more than threshold value E, therefore escalator 1 continues to run well. Show that output valve C is more than the situation of threshold value D (second threshold) in Fig. 4 (b).It is extremely short in the output time as output time Fa In the case of, operational part 9 (control unit 6) is judged as that object collision etc. produces the situation of the displacement of transience, does not make escalator 1 Stop.On the other hand, it is being more than that the displacement of threshold value D continue for the situation of time T2 (the second time) as output time Fb Under, it is judged as clamping foreign matter, into the control for exercising the stopping of escalator 1.In addition, escalator 1 is if desired made more safely to transport Turn, then operational part 9 can also also be controlled such that motor 10 stops in the case of output time Fa.

Fig. 4 (c) shows the situation that output valve C is between threshold value E and threshold value D.When being exported as output time Ga Between it is extremely short in the case of, operational part 9 be judged as object collision etc. produce transience displacement situation, not to monitoring room 11 into Row exception reporting.On the other hand, as output time Gb, output valve C is more than threshold value E (first threshold) and is threshold value D The state of (second threshold) below continue under the state (particular state) of time T1 (first time), and operational part 9 is judged as moving Dynamic handrail 2 is contacted with protective 3a, 3b, and the meaning is reported to monitoring room 11.In this case, operational part 9 stops motor 10 Only.

That is, in the case where output valve C continues a moment between threshold value D and threshold value E, mobile handrail 2 and protective 3a, 3b The possibility for contacting and generating abnormal sound is higher, thus operational part 9 to monitoring room 11 export because produce abnormal sound need into The specific information for the meaning that row is safeguarded.Then, receive the monitoring room 11 of specific information via indoor loud speaker, monitor to Administrator's report needs to be serviced.

Here, in the case where the output from displacement sensor 4a, 4b is output time Fb, due to being that must make automatically The situation of 1 emergent stopping of staircase, the secure context it can be considered to escalator 1 carry out setting time T2.On the other hand, coming In the case that the output of displacement sensor 4a, 4b are output time Gb, although becoming in the presence of since time dependent occurs for mobile handrail 2 Shape and being contacted with protective 3a causes the possibility that abnormal sound generates, but need not carry out emergent stopping.Therefore, if by the time T1 is set as the too short time, then can continually send out alarm instead, some are bothered.Therefore, time T1 is preferably than time T2 long (T1 ＞ T2) and consider the frequency safeguarded suitably to determine.

Next, the control method of the escalator 1 involved by present embodiment is illustrated.Fig. 5 is to show first The flow chart of the sequence of the control process of escalator involved by embodiment.Hereinafter, escalator 1 is illustrated to Fig. 1 A directions (up direction) operating situation.In step sl, the operating side of operational part 9 (control unit 6) detection escalator 1 To.In step s 2, operational part 9 makes displacement sensor 4a, 4b invalidating of top and the bottom according to rotation direction.

That is, in the case of rotation direction A, the inlet port 17 of the upper strata floor 12 of escalator 1 become passenger hand or The side that foreign matter enters, therefore operational part 9 makes displacement sensor 4a effective, and makes displacement sensor 4b invalid.On the contrary, automatic In the case that staircase 1 carries out downlink operating, operational part 9 makes the displacement sensor 4b of 18 side of inlet port of lower floor's floor 13 effective, And make displacement sensor 4a invalid.The displacement sensor of a side is only monitored as a result, to control escalator 1, therefore can Mitigate the control burden of control unit 6.

In step s3, the movement of protective 3a is detected by displacement sensor 4a, and output is recorded by signal section 7 Value, output time.In step s 4, by operational part 9 to the output valve C recorded by signal section 7 and the threshold being stored in storage part 8 Value is compared.In the situation (S4/ is no) of the output valve C for threshold value D, E for being not above being recorded in storage part 8, return again Step S3 is returned to, continues to detect by displacement sensor 4a.There is a situation where the output valve C more than threshold value D, E (S4/ is) Under, 9 implementation steps S5 of operational part.

In step s 5, whether judgement output valve C is more than threshold value D.It is being determined as that output valve C is more than the situation of threshold value D Under (S5/ is), it is possible to need to stop escalator 1, therefore operational part 9 performs step S6.It is being judged to being less than threshold value D Situation (S5/ is no) under, operational part 9 performs step S9.

In step s 6, judge the lasting output times of the output valve C detected by signal section 7.It is deposited than being stored in advance in In the situation (S6/ is no) of output valve C as output time Fa short time T2 in storage portion 8, it is considered as the generations such as object collision The situation of the output of transience simultaneously again returns to step S3.On the other hand, continue in the output valve C as output time Fb In situations (S6/ is) of the time T2 more than threshold value D, operational part 9 is judged as that sandwiching for foreign matter has occurred, and performs step S7.

In the step s 7, sandwiching for foreign matter has occurred and needs to make automatic because sensing escalator 1 in step s 6 1 emergent stopping of staircase, so operational part 9 reports the meaning for stopping escalator 1 for purpose that passenger pays attention to is caused.So Afterwards, in step s 8, operational part 9 stops the driving of motor 10, and escalator 1 is made to shut down.

On the other hand, in step s 9, in the lasting output times of the output valve C detected by signal section 7 deposited than in advance In situation (S9/ is no) as the short Ga of output time of the storage in storage part 8, it is considered as object collision etc. and produces transience The situation of output simultaneously again returns to step S3.Situation (the S9/ that time T1 is more than threshold value E is continue in the output valve C as Gb It is) under, operational part 9 is judged as that mobile handrail 2 contacts with protective 3a and produces abnormal sound, so as to be controlled in step slo System so that export specific information, the meaning that report needs to be serviced etc. to monitoring room 11.At this point, motor 10 continues to rotate. That is, escalator 1 does not stop.

Then, the administrator in monitoring room 11 receives this report, such as to mobile handrail 2 after business operating terminates It is safeguarded, thus, it is possible to be adjusted so that not generating abnormal sound.In this way, according to the present embodiment, in addition to that can be based on Other than the emergent stopping of the escalator 1 sandwiched etc. of foreign matter, additionally it is possible to which early detection simultaneously improves caused by the generation of abnormal sound Failure.

[second embodiment]

Next, second embodiment of the present invention is illustrated.In addition, it omits to identical with first embodiment The explanation of structure.Fig. 6 is the flow chart of the sequence for the control process for showing the escalator involved by second embodiment. In two embodiments, it is to have added the processing of step S11 with the difference of first embodiment.

In step s 11, although being more than threshold like that in the such as Ga of Fig. 4 (c) of the output valve from displacement sensor 4a Value E but output time it is shorter than time T1 in the case of, judge the output whether be transience output processing.That is, Even if in the case where the output time more than threshold value E is shorter than time T1, it is periodic in the output, is helped in movement The possibility that hand 2 is attached with the foreign matters such as chewing gum is also higher.In this case, it needs the mobile handrail 2 such as to clean, therefore Output even more than threshold value E is less than time T1, in the case where the output is detected periodically, in step s 11 As "Yes", operational part 9 is controlled so that reports alarm to monitoring room 11.

On the other hand, in step s 11 for "No" in the case of, be considered as the output of transience and back to step S3. In the second embodiment, the abnormal sound caused by the ongoing change of mobile handrail 2 can not only be detected, additionally it is possible to detect foreign matter Attachment.Therefore, it is possible to which by carrying out cleaning etc. to remove foreign matter as early as possible to mobile handrail 2, escalator 1 can be kept well Operating.

[third embodiment]

Next, third embodiment of the present invention is illustrated.In addition, omission pair is identical with second embodiment The explanation of structure.Fig. 7 is the flow chart of the sequence for the control process for showing the escalator involved by third embodiment. In three embodiments, it is to have added the processing of step S12 with the difference of second embodiment.

Even if the situation that mobile handrail 2 contact with protective 3a when deforming by the time occurs, the entire of handrail 2 is moved Situation about deforming is also seldom within one week, and contact site is a part in most cases.Therefore, in the situation for considering maintainability Under, it is desired to be able to it is readily determined the deformation position of mobile handrail 2.

Therefore, in the third embodiment, become such as lower structure, that is, can report the output from displacement sensor 4a Position more than threshold value E is which part of mobile handrail 2.Specifically, to the step as benchmark in multiple steps 15 15 enclose label (not shown), detect the label by optical sensor etc. (not shown) and input the detection signal to control unit 6.

Loopy moving is carried out since step 15 is synchronous with mobile handrail 2, as long as detouring as the step 15 of benchmark Step 15 and the relationship of the output of displacement sensor 4a are analyzed during one week, it will be able to be determined to become the step of benchmark 15 and the deformation position of the mobile handrail 2 more than threshold value E or foreign matter attachment area.

The analysis is carried out by operational part 9 in step s 12, so as to which operational part 9 is produced in addition to that can be reported to monitoring room 11 It has given birth to other than abnormal sound, additionally it is possible to the information (letter of abnormal position for the reason of which of mobile handrail 2 of report part becomes abnormal sound Breath).Therefore, in the third embodiment, the efficiency of upkeep operation is improved.

More than, embodiments of the present invention are illustrated, but the structure illustrated in the embodiment of front is only one Example, the present invention can suitably change in the range of technological thought is not departed from.For example, it is also possible to replace displacement sensor 4a, 4b and use detection be applied to protective 3a, 3b pressure pressure sensor.In this case, as long as by above-mentioned reality The displacement sensor for applying mode is replaced into pressure sensor to be controlled.Although in addition, be configured in step s 2 into Row selects the processing of the invalidating of displacement sensor 4a, 4b according to the rotation direction of escalator 1, but may not necessarily Centainly carry out the processing.
