In the present embodiment, it is being arranged at the inlet port 17 of the side of upper strata floor 12 and is being arranged at entering for the side of lower floor's floor 13
At entrance 18, it is separately installed with for preventing from sandwiching the safety device of foreign matter, hand.Safety device for being arranged on inlet port 17
Each key element, enclose a at the end of symbol, each key element of the safety device for being arranged on inlet port 18, at the end of symbol
B is enclosed, is distinguish between with this, but safety device 20a is identical with safety device 20b structure, therefore the following description is main
Safety device 20a is illustrated, the explanation to safety device 20b is omitted.
Then, safety device 20a details is illustrated referring to the drawings.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 possesses：It is arranged on inlet port 17
The position of inner portions, the moving direction (Fig. 2 A directions) that can move along handrail 2 moves the protective of (displacement)
3a；For the displacement transducer 4a for the amount of movement (displacement) for sensing protective 3a；And supporting displacement transducer 4a supporting
Part 5a.In addition, protective 3a is for example made up of rubber, but its material is simultaneously unrestricted.
Protective 3a is arranged in inlet port 17 so that do not contacted when escalator 1 runs well with mobile handrail 2,
But if protective 3a is contacted with mobile handrail 2 due to some undesirable conditions, protective 3a moved handrail 2 draw and to
Fig. 2 B directions are subjected to displacement.The protective 3a states for being in initial position are not connect with mobile handrail 2 by displacement transducer 4a
Tactile state is set to zero shift and detects protective 3a displacement all the time, and to the output detection data of control unit 6.Then, as rear
As stating, relation pair escalator 1 of the control unit 6 based on the output valve from displacement transducer 4a and each threshold value D, E is carried out
Control so that report as defined in carrying out makes the emergent stopping of motor 10.
Fig. 3 is the block diagram for the electrical structure for showing escalator.Information from safety device 20a (comes from displacement sensing
Device 4a, 4b detection signal) outside i.e. monitoring room 11 is output to via control unit 6, the monitor in monitoring room 11 is shown respectively
Plant information.Keeper look at various information while carrying out the management of escalator 1.Control unit 6 possesses signal section 7, storage
Portion 8 and operational part 9.Signal section 7 possesses following function, i.e. by the displacement of the protective 3a detected by displacement transducer 4a
Output valve and output time storage certain time, storage part 8 possesses following function, i.e. storage and tong, sandwich foreign matter so
Each detection pattern is corresponding, each threshold value of output valve and output time, operational part 9 possesses following function, i.e. will be by signal section
Each threshold value of the output valve and output time of the sensor of 7 detections with record in storage part 8 is compared, based on comparative result
Motor 10 is controlled, so that escalator 1 stops or generates the abnormal meaning to the report of monitoring room 11.
Fig. 4 is the figure of one for representing the output valve (output quantity) from sensor.In Fig. 4, output valve C is represented by believing
The output valve from displacement transducer 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, " first thresholds " of the threshold value E equivalent to the present invention, " Second Thresholds " of the threshold value D equivalent to the present invention.
The relation of output valve and output time when Fig. 4 (a) shows normal.Passed by what signal section 7 was detected from displacement
Sensor 4a, 4b output valve C are both no more than threshold value D, also no more than threshold value E, therefore escalator 1 proceeds to run well.
Show that output valve C exceedes threshold value D (Second Threshold) situation 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. generates the situation of the displacement of transience, and escalator 1 is not made
Stop.On the other hand, the situation of time T2 (the second time) is continue in the displacement more than threshold value D as output time Fb
Under, it is judged as clamping foreign matter, enters to exercise the control of the stopping of escalator 1.In addition, if desired making escalator 1 more safely 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. generate transience displacement situation, do not enter to monitoring room 11
Row exception reporting.On the other hand, as output time Gb, output valve C exceedes 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 (very 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 producing abnormal sound is higher, thus operational part 9 to monitoring room 11 export because generate abnormal sound need into
The customizing messages for the meaning that row is safeguarded.Then, receive the monitoring room 11 of customizing messages via indoor loudspeaker, monitor to
Keeper's report is needed to be serviced.
Here, in the case where being output as output time Fb from displacement transducer 4a, 4b, due to being that must make automatically
The situation of the emergent stopping of staircase 1, setting time T2 is carried out it can be considered to the secure context of escalator 1.On the other hand, coming
In the case that displacement transducer 4a, 4b are output as output time Gb, although exist and become because time dependent occurs for mobile handrail 2
Shape and being contacted with protective 3a causes the possibility that abnormal sound is produced, but need not carry out emergent stopping.Therefore, if by the time
T1 is set to the too short time, then can continually send alarm on the contrary, some are bothered.Therefore, time T1 is preferably longer than time T2
(T1 ＞ T2) and consider the frequency safeguarded suitably to determine.
Next, the control method to the escalator 1 involved by present embodiment is illustrated.Fig. 5 is to show first
The flow chart of the order 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, operational part 9 (control unit 6) detects the operating side of escalator 1
To.In step s 2, operational part 9 makes displacement transducer 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 turn into passenger hand or
The side that foreign matter enters, therefore operational part 9 makes displacement transducer 4a effectively, and make displacement transducer 4b invalid.On the contrary, automatic
In the case that staircase 1 carries out descending operating, operational part 9 makes the displacement transducer 4b of the side of inlet port 18 of lower floor's floor 13 effectively,
And make displacement transducer 4a invalid.Thus, the displacement transducer of a side is only monitored to control escalator 1, therefore, it is possible to
Mitigate the control burden of control unit 6.
In step s3, protective 3a motion is detected by displacement transducer 4a, and records by signal section 7 output
Value, output time.In step s 4, by 9 couples of output valve C recorded by signal section 7 of operational part and the threshold being stored in storage part 8
Value is compared.In the case where being not above recording the output valve C situation (S4/ is no) of threshold value D, E in storage part 8, return again
Step S3 is returned to, detection is proceeded by displacement transducer 4a.There is a situation where the output valve C more than threshold value D, E (S4/ is)
Under, the implementation steps S5 of operational part 9.
In step s 5, judge whether output valve C exceedes threshold value D.It is being determined as situations of the output valve C more than 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 determined as not less than threshold value D
Situation (S5/ is no) under, operational part 9 performs step S9.
In step s 6, the lasting output times of the output valve C detected by signal section 7 are judged.Deposited than being stored in advance in
In output valve C situation (S6/ is no) as output time Fa short time T2 in storage portion 8, it is considered as object collision etc. and produces
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
Time T2 exceedes in threshold value D situation (S6/ is), and operational part 9 is judged as there occurs sandwiching for foreign matter, performs step S7.
In the step s 7, it there occurs sandwiching for foreign matter because sensing escalator 1 in step s 6 and need to make automatically
The emergent stopping of staircase 1, so operational part 9 reports the meaning for stopping escalator 1 for purpose that passenger notes is caused.So
Afterwards, in step s 8, operational part 9 stops the driving of motor 10, escalator 1 is shut down.
On the other hand, in step s 9, it is than depositing in advance in the lasting output times of the output valve C detected by signal section 7
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 generates transience
The situation of output simultaneously again returns to step S3.Situation (the S9/ that time T1 exceedes threshold value E is continue in the output valve C as Gb
It is) under, operational part 9 is judged as that moving handrail 2 contacts with protective 3a and generate abnormal sound, so as to be controlled in step slo
System so that export customizing messages, the meaning that report is needed to be serviced etc. to monitoring room 11.Now, motor 10 continues to rotate.
That is, escalator 1 does not stop.
Then, the keeper in monitoring room 11 receives this report, such as to mobile handrail 2 after business operating terminates
Safeguarded, thus, it is possible to be adjusted so that not producing abnormal sound.So, according to present embodiment, except that can be based on
Beyond 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, being illustrated to second embodiment of the present invention.In addition, omission pair and first embodiment identical
The explanation of structure.Fig. 6 is the flow chart of the order for the control process for showing the escalator involved by second embodiment.
In two embodiments, the difference with first embodiment is the processing for having added step S11.
In step s 11, although exceeding threshold like that in such as Fig. 4 (c) Ga of the output valve from displacement transducer 4a
Value E but output time it is shorter than time T1 in the case of, carry out judge the output whether be transience output processing.That is,
In the case that the output time more than threshold value E is shorter than time T1, in the case of the output is periodically, 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 is necessary to be cleaned etc. to mobile handrail 2, 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 report 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 return to step S3.
In the second embodiment, the abnormal sound caused by the rheological parameters' change with time of mobile handrail 2 can not only be detected, additionally it is possible to detect foreign matter
Attachment.Therefore, it is possible to remove foreign matter as early as possible by mobile handrail 2 clean etc., escalator 1 can be kept well
Operating.
[the 3rd embodiment]
Next, being illustrated to third embodiment of the present invention.In addition, omission pair and second embodiment identical
The explanation of structure.Fig. 7 is the flow chart of the order for the control process for showing the escalator involved by the 3rd embodiment.
In three embodiments, the difference with second embodiment is the processing for having added step S12.
Even if moving the situation generation that handrail 2 is contacted because deforming by the time with protective 3a, the whole of handrail 2 is moved
Also seldom, contact site is a part to situation about deforming for one week in most cases.Therefore, the situation of maintainability is being considered
Under, it is desired to be able to it is readily determined the deformation position of mobile handrail 2.
Therefore, in the third embodiment, as following structure, i.e. the output from displacement transducer 4a can be reported
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 mark (not shown), detect the mark by optical sensor etc. (not shown) and input the detection signal to control unit 6.
Due to step 15 and mobile handrail 2 synchronously be circulated movement, as long as therefore being detoured in the step 15 as benchmark
Step 15 and the relation of displacement transducer 4a output are analyzed during one week, it becomes possible to be determined to become the step of benchmark
15 and the deformation position or foreign matter attachment area of mobile handrail 2 more than threshold value E.
The analysis is carried out by operational part 9 in step s 12, so that operational part 9 is produced except that can be reported to monitoring room 11
Give birth to beyond abnormal sound, additionally it is possible to the information (letter of abnormal position for the reason for which of mobile handrail 2 of report part turns into 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 embodiment above is only one
Example, the present invention can suitably be changed in the range of technological thought is not departed from.For example, it is also possible to replace displacement transducer
4a, 4b and using detection put on protective 3a, 3b pressure pressure sensor.In this case, as long as by above-mentioned reality
The displacement transducer for applying mode is replaced into pressure sensor to be controlled.In addition, although be configured to enter in step s 2
Row selects the processing of displacement transducer 4a, 4b invalidating according to the rotation direction of escalator 1, but may not necessarily
Necessarily carry out the processing.
