Detailed Description
Embodiment mode 1
A passenger conveyor according to embodiment 1 will be described. Fig. 1 is a side view schematically showing the structure of a passenger conveyor 100 of the present embodiment. In the present embodiment, an escalator is exemplified as the passenger conveyor 100.
As shown in fig. 1, the passenger conveyor 100 has a truss 11 erected between the floor of an upper deck 121 and the floor of a lower deck 122. The truss 11 is provided with a plurality of steps 12. The plurality of steps 12 are connected to each other by a pair of endless step chains 13 disposed on both sides in the width direction of the plurality of steps 12.
A drive machine 14, a pair of step sprockets 15a driven by the drive machine 14, and a control panel 16 for controlling the drive machine 14 are provided at the end of the truss 11 on the upper deck 121 side. A pair of step chains 13 are wound around the pair of step sprockets 15a, respectively. The plurality of steps 12 are cyclically moved by the driving force of the driving machine 14 transmitted via the step sprocket 15a and the step chain 13.
The circulation path of the steps 12 includes an outward path 20, an upper reversing section 15, a return path 21, and a lower reversing section 17. The outward route 20 is a path for transporting passengers using the steps 12. The return path 21 is a path along which the steps 12 move in the direction opposite to the outward path 20, and is located below the outward path 20. The moving direction of the step 12 is reversed at the upper reversing portion 15 and the lower reversing portion 17, respectively. The upper inversion portion 15 is provided at the end of the truss 11 on the upper layer 121 side. The lower inversion portion 17 is provided at the end of the truss 11 on the lower floor 122 side. In the circulation path of the steps 12, the upper reversing section 15 is located between one end of the outward route 20 and one end of the return route 21, and the lower reversing section 17 is located between the other end of the outward route 20 and the other end of the return route 21.
When the passenger conveyor 100 is in the ascending operation, the steps 12 sequentially circulate through the outward path 20, the upper reversing section 15, the return path 21, and the lower reversing section 17. When the passenger conveyor 100 is in a descending operation, the steps 12 sequentially circulate through the outward path 20, the lower reversing section 17, the return path 21, and the upper reversing section 15.
A pair of balustrades 18 facing each other across the plurality of steps 12 is provided on the upper portion of the truss 11. An annular moving handrail 19 that moves together with the plurality of steps 12 is provided at the peripheral edge of each of the pair of balustrades 18.
Fig. 2 is an enlarged view of the step 12 located at the a portion of fig. 1, that is, the step 12 located at the lower horizontal portion on the return path 21 side. Fig. 2 shows a cross section obtained by cutting the step 12 with a plane including both the vertical direction and the moving direction of the step 12. The thick arrows in fig. 2 indicate the moving direction of the steps 12. The steps 12 move from the lower reversing portion 17 toward the upper reversing portion 15 in the return path 21. That is, the passenger conveyor 100 performs a lowering operation.
As shown in fig. 2, the step 12 has a step main body 29, a pair of drive rollers 34 and a pair of follower rollers 36 attached to the step main body 29, respectively. The step body 29 includes a tread 30, a riser 31, a step bracket 32, a step shaft 33, and a pair of follow roller shafts 35. The drive roller 34, the follow roller 36, and the follow roller shaft 35 are provided one on each of both sides of the step 12 in the width direction.
The step 30 is a rectangular flat plate-like member on which the passenger rides. When the step 12 is positioned on the return path 21, the tread 30a of the step 30 faces downward. On the other hand, when the step 12 is positioned on the outward route 20, the tread surface 30a is oriented upward and horizontal, as shown in fig. 7 described later. The riser 31 is provided in front of the step 30 during the lowering operation, that is, behind the step 30 during the raising operation.
The step support 32 supports the tread plate 30 and the riser plate 31. The step bracket 32 has a pair of side frame portions 32a, and the pair of side frame portions 32a are disposed one on each of both sides in the width direction of the step 12. The pair of side frame portions 32a are each formed in a triangular frame shape. One side 32b1 of the side frame portion 32a is disposed along the step 30. The side frame portion 32a has a follow roller mounting portion 32c to which the follow roller 36 is mounted. The follow roller attachment portion 32c is provided to protrude outward of the side frame portion 32a from a corner portion 32b2 of the side frame portion 32a facing the side 32b 1.
The follower roller mounting portion 32c is a portion farthest from the step main body 29 from the tread plate 30. When the step 12 is positioned on the return path 21, that is, when the tread surface 30a of the step 30 is directed downward, the follower roller mounting portion 32c is positioned uppermost in the step main body 29. That is, when the step 12 is positioned on the return path 21, the follow roller mounting portion 32c becomes the top portion of the step main body 29. When the step 12 is positioned on the outward route 20, that is, when the tread surface 30a of the tread 30 is directed upward, the follower roller mounting portion 32c is positioned lowermost in the step body 29. That is, when the step 12 is positioned on the outward path 20, the follower roller mounting portion 32c becomes the bottom portion of the step main body 29.
The tracking roller mounting portion 32c has a detection target surface 32d to be detected by an abnormality detection device 50 or an abnormality detection device 51 described later. When the step 12 is positioned on the return path 21, the detection surface 32d faces upward. When the step 12 is positioned on the outward route 20, the detection surface 32d faces downward.
The step shaft 33 is provided at the rear of the step support 32 during the lowering operation. The step shaft 33 extends in the width direction of the step 12 and penetrates the pair of side frame portions 32 a. The step shafts 33 are connected to the pair of step chains 13 at both ends thereof. Step shafts 33 of the plurality of steps 12 are connected to each step chain 13 at a fixed pitch.
The drive rollers 34 are attached to both end portions of the step shaft 33. That is, the drive roller 34 is attached to the rear portion of the step ladder 32 during the lowering operation, that is, the front portion of the step ladder 32 during the raising operation, via the step shaft 33.
The follow roller shaft 35 is attached to the follow roller attachment portion 32c and extends in the width direction of the step 12. The follow roller 36 is attached to the follow roller shaft 35. That is, the tracking roller 36 is mounted to the tracking roller mounting unit 32c via the tracking roller shaft 35. The follower roller 36 is located forward of the drive roller 34 during the lowering operation and rearward of the drive roller 34 during the raising operation.
A drive rail 37 and a follower roller 36 are fixed to the truss 11. When the steps 12 are pulled by the pair of step chains 13, the drive roller 34 is guided by the drive rail 37, and the follower roller 36 is guided by the follower rail 38.
Returning to fig. 1, the passenger conveyor 100 further includes an abnormality detection device 50 and an abnormality detection device 51. The abnormality detection device 50 and the abnormality detection device 51 are one of safety devices provided in the passenger conveyor 100.
The abnormality detection device 50 and the abnormality detection device 51 are both provided below the steps 12 in the outbound path 20. The abnormality detection device 50 and the abnormality detection device 51 are each configured to detect an abnormal displacement of the tracking roller mounting portion 32c in the downward direction with respect to the tracking rail 38, that is, a sinking of the step 12 in the outbound path 20. The abnormality detection devices 50 are provided one on each of the left and right sides of the inclined portion near the entrance of the upper layer 121 via the step 12. The abnormality detection devices 51 are provided one on each of the left and right sides of the inclined portion near the entrance of the lower stage 122 via the steps 12.
Fig. 3 is a side view showing the structure of the abnormality detection device 50 of the passenger conveyor 100 according to the present embodiment. Although the configuration of one abnormality detection device 50 of the two abnormality detection devices 50 will be described below, the other abnormality detection device 50 of the two abnormality detection devices 50 and the two abnormality detection devices 51 also have the same configuration.
As shown in fig. 3, the abnormality detection device 50 includes a shaft 61, a cam 62, and an operation piece 63 as a mechanism for detecting an abnormality. The shaft portion 61 extends in the width direction of the step 12, and is rotatably supported by a bearing not shown. The cam 62 has a disc shape coaxial with the shaft portion 61, and is fixed to the shaft portion 61. A groove-shaped recess 64 extending in the axial direction is formed in a part of the outer peripheral surface of the cam 62. The operation piece 63 is fixed to the shaft portion 61 and protrudes upward from the shaft portion 61.
The abnormality detection device 50 has a switch 66 provided with a button 65. The push button 65 is inserted into the recess 64 of the cam 62 in an undepressed state.
When viewed along the moving direction of the step 12 without causing the step 12 to sink, the follower roller mounting portion 32c and the moving piece 63 are separated from each other. Therefore, when the step 12 does not sink, the operation piece 63 does not contact the follower roller mounting portion 32 c. Here, the state in which the step 12 is not sunk includes not only a state in which the downward displacement of the tracking roller mounting portion 32c is not generated at all but also a state in which the downward displacement of the tracking roller mounting portion 32c with respect to the tracking rail 38 is within an appropriate range.
When the follower roller 36 is damaged or comes off, the step 12 sinks, and the follower roller mounting portion 32c is displaced downward. When the downward displacement of the tracking roller mounting portion 32c relative to the tracking rail 38 increases beyond an appropriate range, the operation piece 63 comes into contact with the detection surface 32d of the tracking roller mounting portion 32c when the step 12 passes through the abnormality detection device 50. The operation piece 63 in contact with the follow roller mounting portion 32c is pressed by the follow roller mounting portion 32c in the movement direction of the step 12, and rotates together with the shaft portion 61 and the cam 62. When the cam 62 rotates, the button 65 is pressed by the cam 62, and the switch 66 is operated. As a result, the abnormality detection device 50 detects the downward abnormal displacement of the follower roller mounting portion 32c, that is, the downward movement of the step 12. When the sinking of the steps 12 is detected, an abnormality detection signal is output from the abnormality detection device 50 to the control panel 16, and the operation of the passenger conveyor 100 is stopped by the control of the control panel 16.
Returning to fig. 1, the passenger conveyor 100 further includes an abnormality detection device 52 and an abnormality detection device 53. The abnormality detection device 52 and the abnormality detection device 53 are one of the safety devices provided in the passenger conveyor 100.
The abnormality detection device 52 and the abnormality detection device 53 are both provided above the steps 12 in the return path 21. The abnormality detection device 52 and the abnormality detection device 53 are each configured to detect an abnormal displacement of the tracking roller mounting portion 32c in the upward direction with respect to the tracking rail 38, that is, a floating of the step 12 in the return path 21. The abnormality detection device 52 is provided at each of the right and left sides of the inclined portion near the upper layer 121 with the step 12 interposed therebetween. The abnormality detection device 53 is provided at each of the left and right sides of the step 12 at the inclined portion near the lower layer 122. Each of the two abnormality detectors 52 and 53 has a structure in which the abnormality detector 50 shown in fig. 3 is turned upside down.
Although not shown, when the step 12 does not float, the operation pieces of the two abnormality detectors 52 and 53 do not contact the follower roller mounting portion 32 c. Here, the state in which the rising of the step 12 is not generated includes not only a state in which the upward displacement of the tracking roller mounting portion 32c is not generated at all, but also a case in which the upward displacement of the tracking roller mounting portion 32c with respect to the tracking rail 38 is within an appropriate range.
When the step 12 floats, the follow roller mounting portion 32c is displaced upward. When the upward displacement of the tracking roller mounting portion 32c increases beyond an appropriate range, the above-described operation piece comes into contact with the tracking roller mounting portion 32 c. Thus, the abnormality detection device 52 and the abnormality detection device 53 each detect an abnormal displacement upward of the follower roller mounting portion 32c, that is, a floating of the step 12. An abnormality detection signal is output to the control panel 16 from an abnormality detection device that detects the floating of the steps 12.
Each of the anomaly detection devices 50, 51, 52, and 53 according to the present embodiment is a contact-type anomaly detection device including the operation piece 63 that comes into contact with the tracking roller mounting portion 32 c. However, each of the anomaly detection devices 50, 51, 52, and 53 may be a non-contact anomaly detection device including a proximity sensor that detects an anomalous displacement in the vertical direction of the tracking roller mounting portion 32c without contacting the tracking roller mounting portion 32 c.
Returning to fig. 2, the passenger conveyor 100 also has a sweeping device 40. The cleaning device 40 is provided above the step 12 in the return path 21 at a position along the movement locus 39 of the roller mounting portion 32 c. The cleaning device 40 is configured to remove foreign matter such as dust adhering to the tracking roller mounting portion 32 c. In the present embodiment, the cleaning device 40 is configured to remove foreign matter such as dust adhering to the detection surface 32d of the tracking roller mounting portion 32 c. Cleaning device 40 is fixed to truss 11 so as to face detection surface 32 d.
Fig. 4 is a diagram showing a configuration of the cleaning device 40 of the passenger conveyor 100 according to the present embodiment and its surroundings when viewed in the direction C of fig. 2. Here, the direction C of fig. 2 is a direction along the moving direction of the steps 12. Fig. 5 is a perspective view showing the structure of cleaning device 40 of passenger conveyor 100 according to the present embodiment.
As shown in fig. 4 and 5, cleaning device 40 includes metal substrate 41 formed in an L-shaped cross section. The substrate 41 has: a flat plate-like base portion 41 a; a mounting portion 41b provided at one end side of the base portion 41a and bent with respect to the base portion 41 a; and a comb 42 provided on the other end side of the base 41 a. The comb portion 42 is formed in a comb shape having a plurality of ends like a fork. The comb part 42 has a plurality of teeth 42a and at least one cutout part 42b formed between two teeth 42a adjacent to each other. The plurality of teeth 42a protrude from the base portion 41a in one direction in the same plane as the base portion 41 a. In the left-right direction of fig. 4, the comb portion 42 is wider than the width of the tracking roller mounting portion 32 c.
The mounting portion 41b is mounted to the truss 11. The base 41a and the comb 42 are provided along the movement locus 39 of the roller mounting portion 32 c. The base 41a and the comb 42 are disposed at a distance L1 from the movement locus 39. That is, the base portion 41a and the comb portion 42 are disposed at a position separated from the follower roller mounting portion 32c by a distance L1 when viewed along the moving direction of the steps 12. The distance L1 is, for example, about 5 mm. A gap 43 is formed between the comb 42 and the moving locus 39. The comb 42 is provided such that the protruding direction of the plurality of teeth 42a is parallel to and opposite to the moving direction of the steps 12.
The cleaning device 40 also has a brush portion 44 that contacts the tracking roller mounting portion 32 c. The brush portion 44 is provided on the surface 41a1 on the step bracket 32 side of the base portion 41 a. In the left-right direction of fig. 4, the width of the brush portion 44 is wider than the width of the tracking roller mounting portion 32 c. The brush portion 44 has a plurality of resin bristles 44a planted on the surface 41a1 of the base portion 41 a. Each of the bristles 44a extends perpendicularly from the surface 41a1 of the base 41a so as to reach the movement locus 39 following the roller mounting portion 32c or so as to exceed the movement locus 39. That is, the length L2 of each of the hair materials 44a is equal to or greater than the distance L1. Thereby, at least a part of the hair materials 44a of the plurality of hair materials 44a comes into contact with the detection surface 32d of the tracking roller mounting portion 32 c.
The brush portion 44 is arranged forward of the comb portion 42 in the moving direction of the steps 12. That is, the brush portion 44 is disposed behind the comb portion 42 in the relative movement direction of the cleaning device 40 with respect to the steps 12. Thereby, the tracking roller mounting portion 32c passes through the brush portion 44 after passing through the comb portion 42.
Fig. 6 is a diagram showing a state in which foreign matter 70 adheres to the tracking roller mounting portion 32c in the passenger conveyor 100 according to the present embodiment. In the state shown in fig. 6, foreign matter 70 formed integrally with a thread end 70a, hair 70b, cotton wool 70c, and the like is wound around the follower roller mounting portion 32c and the follower roller shaft 35 around the same.
When the tracking roller mounting portion 32c approaches the cleaning device 40 along with the movement of the step 12, the foreign matter 70 attached to the tracking roller mounting portion 32c first comes into contact with the comb portion 42. When the tracking roller mounting portion 32c further approaches the cleaning device 40, the teeth 42a of the comb-shaped portion 42 bite into the foreign matter 70. The foreign matter 70 stuck into the teeth 42a is torn off and removed by the teeth 42a as the step 12 moves. Thereby, most of the foreign matter 70 is removed from the follow roller mounting portion 32 c.
After that, the tracking roller mounting portion 32c contacts the brush portion 44. The debris of the foreign matter 70 remaining in the follower roller mounting portion 32c is wiped off by the plurality of bristles 44a of the brush portion 44 as the step 12 moves. Thereby, the foreign matter 70 is removed from the tracking roller mounting portion 32 c.
If the step 12 with the foreign matter 70 adhering to the follow-up roller mounting portion 32c passes through the abnormality detection device 50 shown in fig. 3, the operation piece 63 may come into contact with the foreign matter 70, and false detection by the abnormality detection device 50 may occur. Here, the erroneous detection by the abnormality detection device 50 means that the abnormal displacement in the vertical direction of the step 12 is detected even though the abnormal displacement in the vertical direction of the step 12 does not occur. In contrast, in the present embodiment, since the foreign matter 70 adhering to the tracking roller mounting portion 32c can be removed by the cleaning device 40, erroneous detection by the abnormality detection device 50 can be suppressed.
The installation position of cleaning device 40 is not limited to part a of fig. 1, and may be any position as long as it is a position along the circulation path of steps 12. Fig. 7 is an enlarged view of the step 12 located at the B portion of fig. 1, that is, the step 12 located at the lower horizontal portion on the outward route 20 side. Fig. 8 is a view showing the structure of the passenger conveyor and its surroundings according to the present embodiment when viewed in the direction D of fig. 7. Here, the direction D of fig. 7 is a direction along the moving direction of the steps 12. In the example shown in fig. 7 and 8, cleaning device 40 is provided at a position along the lower horizontal portion on the outward path 20 side. The step 12 moves from the lower reversing portion 17 toward the upper reversing portion 15 in the outward route 20. That is, in the example shown in fig. 7 and 8, the passenger conveyor 100 performs the ascending operation.
As shown in fig. 7 and 8, when the step 12 is positioned on the outward route 20, that is, when the tread surface 30a of the tread 30 is directed upward, the follower roller mounting portion 32c is positioned lowermost in the step body 29. The cleaning device 40 is provided below the steps 12 in the outward path 20 and at a position along the movement locus 39 of the roller mounting portion 32 c. The cleaning device 40 has a configuration in which the configuration of the cleaning device 40 shown in fig. 2 and 4 is reversed upside down, and the positional relationship between the cleaning device 40 and the follower roller mounting portion 32c is a positional relationship in which the positional relationship between the cleaning device 40 and the follower roller mounting portion 32c shown in fig. 2 and 4 is reversed upside down. According to the configurations shown in fig. 7 and 8, the same effects as those of the configurations shown in fig. 2 and 4 can be obtained.
The position where cleaning device 40 is installed may be a position along an upper horizontal portion or inclined portion on the outbound path 20 side, or may be a position along an upper horizontal portion or inclined portion on the return path 21 side. The position where the cleaning device 40 is installed may be a position along the upper reversing part 15 or the lower reversing part 17. Even if cleaning device 40 is provided in these portions, the same effect can be obtained.
In the configuration shown in fig. 2 or 7, when the moving direction of the steps 12 is reversed, the direction of the cleaning device 40 may be reversed. Even in this case, the same effect can be obtained.
In the present embodiment, the escalator is exemplified as the passenger conveyor 100, but the present embodiment can be applied to other passenger conveyors such as a moving sidewalk.
As described above, the passenger conveyor 100 of the present embodiment includes the steps 12, the follow rail 38, the abnormality detection devices 50, 51, 52, and 53, and the cleaning device 40. The step 12 is configured to have a step main body 29 and a follower roller 36, and to move cyclically, the step main body 29 has a follower roller mounting portion 32c, and the follower roller 36 is mounted to the follower roller mounting portion 32 c. The tracking rail 38 is configured to guide the tracking roller 36. The abnormality detection devices 50, 51, 52, and 53 are configured to detect an abnormal displacement of the tracking roller mounting portion 32c in the vertical direction with respect to the tracking rail 38. The cleaning device 40 is configured to remove the foreign matter 70 adhering to the follower roller mounting portion 32 c.
If foreign matter 70 adheres to the tracking roller mounting portion 32c, each of the abnormality detectors 50, 51, 52, and 53 may erroneously detect the foreign matter. In contrast, according to the above configuration, since the foreign matter 70 adhering to the tracking roller mounting portion 32c can be removed by the cleaning device 40, erroneous detection by each of the abnormality detection devices 50, 51, 52, and 53 can be suppressed.
In the passenger conveyor 100 of the present embodiment, the cleaning device 40 has the comb-shaped portion 42, and the comb-shaped portion 42 has a plurality of teeth 42a protruding in one direction. The comb 42 is provided along the movement locus 39 of the roller mounting portion 32 c. The plurality of teeth 42a protrude in a direction opposite to the moving direction of the steps 12. With this configuration, the foreign matter 70 attached to the tracking roller mounting portion 32c can be torn off and removed by the plurality of teeth 42a by the movement of the step 12. Therefore, the foreign matter 70 can be more reliably removed. Therefore, erroneous detection by each of the abnormality detectors 50, 51, 52, and 53 can be more reliably suppressed.
In the passenger conveyor 100 of the present embodiment, the cleaning device 40 includes the brush portion 44 that contacts the follower roller mounting portion 32 c. According to this configuration, the foreign matter 70 adhering to the tracking roller mounting portion 32c can be wiped off by the brush portion 44 by the movement of the step 12, and therefore the foreign matter 70 can be more reliably removed. Therefore, erroneous detection by each of the abnormality detectors 50, 51, 52, and 53 can be more reliably suppressed.
In the passenger conveyor 100 of the present embodiment, the cleaning device 40 includes the comb portion 42 and the brush portion 44. The brush portion 44 is arranged forward of the comb portion 42 in the moving direction of the steps 12. According to this configuration, most of the foreign matter 70 adhering to the follow-up roller mounting portion 32c is torn off and removed by the plurality of teeth 42a, and then the remains of the foreign matter 70 are wiped off by the brush portion 44, so that the foreign matter 70 can be more reliably removed. Therefore, erroneous detection by each of the abnormality detectors 50, 51, 52, and 53 can be more reliably suppressed.
