Abstract
The invention discloses a mobile armrest inspection device of a passenger conveyer. An image is restricted by a detection body (5), so that three sets of joints obliquely arranged with respect to the elongation direction of the inner steel wires buried in the mobile armrest (2) are detected.When the abnormity is continuously detected by an image processor (8) and the variation amount delta P of each light amount is within a predetermined range of a time interval delta t, a joint is determined by a determination mechanism.When the variation amount delta P of each light amount is not within thepredetermined range of the time interval delta t, a joint is not determined by the determination mechanism.When the joint is determined, no abnormality on the joint is judged by an abnormality determination mechanism.When the joint is not determined, an abnormality on the joint is judged by the abnormality determination mechanism.Therefore, whether the abnormality of a tension element is existed or not can be quantitatively and fully detected by the inspection device, including the abnormality of the joint of the inner steel wires buried in the mobile armrest (2).
Description
Technical field
The present invention relates to detect the mobile armrest inspection device that on the tension element of the inside of imbedding the moving hand-rail that is arranged on passenger conveyors, whether has produced unusual passenger conveyors.
Background technology
Generally speaking, passenger conveyors possesses the passenger on the pedal and prevents from toppling over the moving hand-rail of controlling, cooperating the ring-type of walking with the guiding rail of railing.This moving hand-rail is made of elastic bodys such as rubber, and this elastic body loses tension force owing to temperature traverse and long-term use etc. sometimes, causes and can't tensioning be arranged in the guiding rail of railing.In order to prevent this situation, consistently imbed tension elements such as being provided with many steel wires in the inside of moving hand-rail and the prolonging direction of moving hand-rail.
But, imbed the occasion that a plurality of tension elements are set in moving hand-rail inside, because each tension element produces mobilely under the long-term use of these tension elements, perhaps owing to reasons such as own wts, easily produce metal fatigue etc. unusual and rupture.Like this, because tension element fracture and strength decreased, institute thinks and prevents this from occurring, and needs the tension element of periodic inspection moving hand-rail inside, detects tension element and has or not and produce unusually, repairs and also changes tension element.
Thus, one of them example of the mobile armrest inspection device of the passenger conveyors that checks as the tension element to imbed setting in moving hand-rail inside such in the prior art, known a kind of escalator handrail diagnostic device (for example with reference to patent documentation 1) has: imbed in inside setting a plurality of tension elements with the loop connecting moving hand-rail; X-ray generator to this moving hand-rail X-ray irradiation is x-ray irradiation device; Acceptance sees through moving hand-rail by this x-ray irradiation device and the light-receiving device of the X ray that comes; The amount of the X ray that this light-receiving device is accepted obtains device as the image that image detects; And the tension element of analyzing and detect moving hand-rail to obtained image that device obtains by this image has N/R image processor, and this image processor has: the X ray equivalent images to moving hand-rail carries out the two-dimensional high speed Fourier transform handling part that the two-dimensional high speed Fourier transform is processed; And the spectral discrimination section of judging the tension element that has or not moving hand-rail based on the result of this two-dimensional high speed Fourier transform handling part, thereby quantitative check imbed have or not on the tension element that is arranged in the moving hand-rail unusual.
In addition, although be not the mobile armrest inspection device that belongs to passenger conveyors, but, as above-mentioned x-ray irradiation device, thereby as adopting X ray subject to be shone the example of prior art of the radiographic apparatus of the data for projection that obtains subject, known have a kind of radiographic apparatus (for example with reference to patent documentation 2), have the X-ray tube that is positioned at rotating side and the collimation section that has aperture device at direction of slip, the X ray that X-ray tube is penetrated by collimation section is removed scattered x-ray and after direction of slip carries out the aperture adjustment to light, subject to fixation side exposes, and obtains the data for projection from the full angle of subject.

The specific embodiment
With reference to the accompanying drawings the mode of the mobile armrest inspection device that is used for passenger conveyors of the present invention described.
(the first embodiment)
As shown in Figure 1, the first embodiment of the mobile armrest inspection device of passenger conveyors of the present invention has: to the x-ray irradiation device 1 with moving hand-rail 2 X-ray irradiations of loop connecting; Acceptance sees through moving hand-rail 2 by this x-ray irradiation device 1 and the light-receiving device 3 of the X ray that comes; The image that the amount of the X ray that this light-receiving device 3 is accepted detects as image obtains for example pick up camera 4 of device; Be connected with this pick up camera 4, the image analysis that is obtained by pick up camera 4 detected the tension element described later of imbedding the inside that is arranged at moving hand-rail 2 N/R image processor 8 is arranged by signal wire (SW) 7.
As shown in Figure 2, moving hand-rail 2 has for example 18 tension elements of a plurality of tension elements in inside, these a plurality of tension elements are that joint 201～209 described later has a plurality of tension elements that the assigned position relation configures, and these tension elements are made of steel wire (ス チ one Le コ one De) 101～118 respectively.In addition, such as Fig. 1, shown in Figure 3, have detection bodies 5 in first embodiment of the invention, 5 pairs of images of being analyzed by image processor 8 of this detection bodies limit, in order to detect at least two joints with respect to the prolonging direction oblique arrangement of steel wire 101～118.This detection bodies 5 is disposed between light-receiving device 3 and the pick up camera 4 as shown in Figure 1, have with respect at least two joints of steel wire 101～118 prolonging direction oblique arrangement slit 5a of tilted configuration as one man.
Specifically, in first embodiment of the invention, as shown in Figure 2,2 of adjacency in the steel wire 101～118 as one group, are processed the joint 201～209 of steel wire 101～118.In addition, if these joints 201～209 are adjacent to each other, then can reduce the intensity of part of the moving hand-rail 2 at joint 201～209 places places, tilt and separate certain intervals so joint 201～209 is arranged in prolonging direction with respect to steel wire 101～118.Its length dimension of arranging along same direction of the slit 5a of the detection bodies 5 that first embodiment of the invention has is set as consistent with three joints in the joint 201～209.
Namely, respectively with joint 201,204,207, joint 202,205,208, joint 203,206,209 as one group, as shown in Figure 3, in the inspection of moving hand-rail 2, by light-receiving device 3 accept to see through joint 201,204,207 X ray and the light that sends with the slit 5a of same opportunity by detection bodies 5.Equally, in the inspection of moving hand-rail 2, by light-receiving device 3 accept to see through joint 202,205,208 X ray and the light that sends with the slit 5a of same opportunity by detection bodies 5, and, by light-receiving device 3 accept to see through joint 202,205,208 X ray and the light that sends with the slit 5a of same opportunity by detection bodies 5.In addition, in first embodiment of the invention, as shown in Figure 1, in these x-ray irradiation devices 1, moving hand-rail 2 as the part that checks object, light-receiving device 3, detection bodies 5, and pick up camera 4 be contained among a pair of cabinet 6a, the 6b.
In addition, image processor 8 inside have identification mechanism, this identification mechanism goes out in the unusual situation of steel wire 101～118 in continuous detecting, detect the change of each unusual light quantity in specialized range, and detect each unusual time gap and assert it is the joint 201～209 of steel wire 101～118 in specialized range the time, when the change that detects each unusual light quantity is outside specialized range and when detecting outside at least one party of each unusual time gap outside specialized range time the scope, assert it is not the joint 201～209 of steel wire 101～118.
And, image processor 8 also has unusual decision mechanism in inside, this unusual decision mechanism is assert that mechanism regards as joint 201～209 o'clock, be judged as and on joint 201～209, do not exist unusually, not joint 201～209 o'clock assert that mechanism is assert, be judged as and exist unusual at joint 201～209.
The below describes the action of the first embodiment of the mobile armrest inspection device of passenger conveyors of the present invention.
Fig. 4 is expression is in the image under the normal condition by the steel wire of the first embodiment in the image of image processor processing shown in Figure 1 figure, Fig. 5 is expression is in the image under the error state by the steel wire of the first embodiment in the image of image processor processing shown in Figure 1 figure, and Fig. 6 is that expression is by the figure of the image of the connector status of the steel wire of the first embodiment in the image of image processor processing shown in Figure 1.
As shown in Figure 1, if from x-ray irradiation device 1 X-ray irradiation, then X ray sees through moving hand-rail 2 and imbeds the steel wire 101～118 that is arranged on moving hand-rail 2 inside.Afterwards, the concurrent bright dipping of light that light-receiving device 3 is accepted through the X ray of moving hand-rail 2 and steel wire 101～118, the light that sends is by the slit 5a of detection bodies 5.And pick up camera 4 obtains the light by slit 5a, by signal wire (SW) 7 image of obtaining is sent to image processor 8.8 pairs of images that receive from pick up camera 4 of image processor carry out Treatment Analysis.
At this moment, the state of the steel wire 101～118 of the inside of corresponding moving hand-rail 2, different by the image that image processor 8 is processed.For example, if the state of steel wire 101～118 is normal state, then as shown in Figure 4, the shadow that the image 11 of being processed by image processor 8 equivalent arrangements and steel wire 101～118 in Slit Image 11a is suitable.
On the other hand, if the state of steel wire 101～118 is error state, then produce the fracture of steel wire 101～118 or to the one-sided phenomenon such as depart from, so, as shown in Figure 5, the image 11 of being processed by image processor 8 shadow partial failure suitable with slit 101～118 in Slit Image 11a is perhaps because gravity etc. are former thereby part is not transfused to.Like this, be under the error state at the state of steel wire 101～118, light amount ratio steel wire 101～118 states that 8 pairs of image analyses of being obtained by pick up camera 4 of image processor obtain are that normal condition lower time is large.
Therefore, image processor 8 as shown in Figure 7, produce at the light quantity P that the image analysis of being obtained by pick up camera 4 is obtained in the situation of change, if the change amount Δ P of this light quantity P is more than predefined light quantity P1, then be judged as at steel wire 101～118 and produced unusually, if and the not enough predefined light quantity P1 of the change amount Δ P of light quantity P then is judged as at steel wire 101～118 unusual less than producing.
Here, if image processor 8 detects the part suitable with joint 201～209, then as shown in Figure 6, the image 11 that image processor 8 is processed, with Slit Image 11a in joint 201,204,207, joint 202,205,208 or joint 203,206,209 suitable each three part in the shadow suitable with steel wire 101～118 damaged, so these three parts are continuously input not.Therefore, the light quantity P that 8 pairs of image analyses of being obtained by pick up camera 4 of image processor obtain and the state of steel wire 101～118 are that the occasion of error state is the same, and be large when being normal condition than the state of steel wire 101～118.
Therefore, image processor 8 and the state of above-mentioned steel wire 101～118 are that the situation of error state is the same, the light quantity P that obtains as shown in Figure 8 the image that is obtained by pick up camera 4 being analyzed produces in the situation of change, if the change amount Δ P of this light quantity P is more than predefined light quantity P1, then be judged as at steel wire 101～118 and produced unusually, and in the situation that image processor 8 continuous detecting go out unusual, the change amount Δ P of each light quantity that this is unusual is in specialized range, and detect this each unusual time gap Δ t in specialized range the time, assert that then it is the joint 201～209 of steel wire 101～118 that mechanism is assert.
On the other hand, in the situation that image processor 8 continuous detecting go out unusual, when the change amount Δ P of this each unusual light quantity is outside specialized range and when detecting outside at least one party of this each unusual time gap Δ t outside specialized range time the scope, assert that it is not the joint 201～209 of steel wire 101～118 that mechanism is assert.
And unusual decision mechanism is assert that mechanism assert that joint 201～209 o'clock then is judged as and does not exist unusually, and is assert that mechanism do not assert that joint 201～209 o'clock is judged as and exists unusual at joint 201～209 on joint 201～209.
Here, although unusual decision mechanism is assert that mechanism do not assert that joint 201～209 o'clock then is judged as and exists unusual at joint 201～209, but, suppose in the situation that joint 201～209 does not have unusually, exist too the metal at steel wire 101～118 partly to have the imaginary unusual same unusual possibility suitable with joint.Yet, for steel wire 101～118 depart from the generation such as gravity unusual for, in the change of the light quantity that does not produce the interval, imbed in the steel wire 101～118 that is arranged on moving hand-rail 2, as mentioned above, joint 201～209 only per two steel wires arranges 1, so unusual decision mechanism is assert that mechanism assert that repeatedly the metal that joint 201～209 o'clock are judged as at steel wire 101～118 partly exists unusually.
First embodiment of the present invention of this structure, as mentioned above, acceptance is larger through the light quantity P of the concurrent bright dipping of X ray of the metal part of steel wire 101～118 than acceptance through the light quantity P of the concurrent bright dipping of X ray of the joint 201～209 of steel wire 101～118 by x-ray irradiation device 1, because the light quantity P in the part suitable with the joint 201～209 of steel wire 101～118 changes, so, analyze metal part and the X ray of joint 201～209 and the light quantity P that sends that the acceptance that is obtained by pick up camera 4 sees through steel wire 101～118 by image processor 8, if the change amount Δ P of light quantity P is more than predefined light quantity P1, then the joint 201～209 with steel wire 101～118 detects unusually as imaginary.
And, by by the slit 5a of detection bodies 5 mode that at least two joints 201～209 with respect to the prolonging direction oblique arrangement of steel wire 101～118 detect being limited the image of being analyzed by image processor 8, thus image processor 8 will with respect to the quantity of the joint 201～209 of the prolonging direction oblique arrangement of steel wire 101～118, be joint 201,204,207, joint 202,205,208 and joint 203,206,209 these three groups as imaginary unusual continuous the detection.
The first embodiment of the present invention, in the situation that image processor 8 continuous detecting are imaginary unusual, assert that mechanism assert that the change amount Δ P of each the unusual light quantity P that is detected by three groups of the slit 5a continuous detecting of detection bodies 5 and time gap Δ t are whether in specialized range, assert the joint 201～209 that steel wire 101～118, the joint 201～209 of steel wire 101～118 must be present in the inside of moving hand-rail 2, so, if the joint 201～209 of steel wire 101～118 is in normal condition, assert then that mechanism must assert and joint 201～209.Therefore, whether assert by this identification mechanism and joint 201～209, abnormal detection mechanism judges uniformly whether the joint 201～209 of steel wire 101～118 produced unusually originally, thus comprise the joint 201～209 of imbedding 18 steel wires 101～118 that are arranged at moving hand-rail 2 inside interior can be quantitatively and fully check steel wire 101～118 have or not produce unusual.
In addition, in the first embodiment of the invention, detection bodies 5 is disposed between light-receiving device 3 and the pick up camera 4, possess and slit 5a with respect at least two joints 201～209 consistent oblique arrangement of the prolonging direction oblique arrangement of steel wire 101～118, owing to the slit 5a that utilizes detection bodies 5 mode that at least two joints 201～209 of the prolonging direction oblique arrangement of relative steel wire 101～118 detect can easily and reliably be limited the image of being analyzed by image processor 8, so, can improve the analysis precision of image processor 8.Therefore, can improve the reliability of device.

As shown in Figure 9, second embodiment of the invention and above-mentioned the first embodiment difference are, steel wire 101～118 is followed moving hand-rail 2 and is formed ring-type in the first embodiment, joint constitutes 201～209 and has the gap, and in the second embodiment, joint 301～309 constitutes overlay structure.Other structure is identical with the first embodiment.
This occasion, image processor 8, as shown in Figure 8, the light quantity P that obtains the image of being obtained by pick up camera 4 is analyzed produces in the situation of change, if image processor 8 detects the part suitable with joint 301～309, then as shown in figure 10, in the image 11 of being processed by image processor 8, with the joint 301 in the Slit Image 11a, 304,307, joint 302,305,308, or joint 303,306, shadow suitable with steel wire 101～118 in 309 suitable three parts is overlapping, the light quantity P that obtains so 8 pairs of images that obtain from pick up camera 4 of image processor are analyzed is opposite with the situation of the first embodiment, is that normal state is little than the state of steel wire 101～118.
Therefore, image processor 8 is got the absolute value of the change amount Δ P of this light quantity P in the situation of the light quantity P change that the image analysis that pick up camera 4 is obtained obtains, thereby can do same processing with the occasion of the first embodiment.
The second embodiment of the present invention that consists of is like this compared the first embodiment, the state of the joint 301～309 of steel wire 101～118 is different, it no matter is the occasion in the overlapping structure of joint 301～309, or the light quantity P that the image analysis of being obtained by pick up camera 4 obtains is produced the occasion of change, the absolute value of change amount Δ P by getting this light quantity P can access effect, the effect identical with the first embodiment.Like this, can coincide with the state of joint and be mapped definitely.
In addition; in first, second embodiment of the present invention; although by the slit 5a of detection bodies 5 mode that at least two joints 201～209,301～309 of the prolonging direction oblique arrangement of relative steel wire 101～118 detect is limited the image of being analyzed by image processor 8; but; also can have mask mechanism that the image obtained by pick up camera 4 is implemented the mask processing replacing detection bodies 5 to have slit 5a by detection bodies 5, thereby make image processor 8 extract specific pixel.Wherein, for the pixel that extracts the border, originally at mask the many situation of regional light quantity under can be subject to its impact, so image processor 8 can carry out revisal and extract specific pixel these.
In addition, in first, second embodiment of the present invention, although be the explanation that steel wire 101～118 carries out as 18 situation take tension element, be not limited only to this occasion, so long as many get final product.
