Embodiment 1
FIG. 1 is a cross-sectional view showing an example of a passenger conveyor according to Embodiment 1 of the present invention. FIG. 1 shows an escalator as an example of a passenger conveyor. Detailed description of other examples of man conveyors such as moving walkways will be omitted.

  The escalator truss 1 is bridged between the upper and lower floors. The truss 1 supports the weight and load of the escalator. The escalator passengers take step 2 as they move between the upper and lower floors. 2 to 4 are diagrams showing an example of step 2. FIG. 2 is a view of step 2 from direction A of FIG. FIG. 4 is a side view showing step 2 only.

  A machine room 4 is formed below the entrance 3. The machine room 4 is a space formed at the upper end of the truss 1. In the machine room 4, for example, a motor 5, a reduction gear 6, and a control device 7 are provided. The motor 5 generates a driving force for driving the step 2. The control device 7 controls the operation of the passenger conveyor. For example, control of the motor 5 is performed by the controller 7. A sprocket 9 is provided on a shaft 8 provided in the machine room 4. The step chain 10 is wound around the sprocket 9. The step chain 10 is endless.

  A machine room 12 is formed below the entrance 11. The machine room 12 is a space formed at the lower end of the truss 1. For example, a tension device 13 is provided in the machine room 12. A sprocket 15 is provided on a shaft 14 provided in the machine room 12. The step chain 10 is wound around the sprocket 15. The step chain 10 moves in the truss 1 in a direction according to the rotation direction of the sprocket 9 as the sprocket 9 rotates.

  The step chain 10 is provided with a step shaft 16. Step 2 is attached to the step shaft 16. By connecting a large number of steps 2 to the step chain 10, the steps 2 are disposed without gaps from the upper entrance 3 to the lower entrance 11.

  A skirt guard 17 is disposed on both sides of step 2. That is, the forward step 2 is disposed between the skirt guards 17. Step 2 moves along the skirt guard 17. The movement of step 2 is guided by the rails 18 and 19. The rails 18 are supported by the truss 1. The rail 19 is supported by the truss 1. A drive roller 20 is rotatably provided at each end of the step shaft 16. The drive roller 20 rolls on the upward surface of the rail 18.

  Step 2 includes, for example, a tread 21, a riser 22, a support member 23 and a driven roller 24 as a basic configuration.

  The tread 21 is a plate-like member on which the escalator passenger actually travels. The riser 22 is a part corresponding to the kicking up in the step 2. The riser 22 extends downward from the edge of the tread 21. The support member 23 supports the tread 21 and the riser 22. For example, the tread 21 and the riser 22 are fixed to the support member 23 by bolts. Further, the support member 23 is provided on the step shaft 16. As the step chain 10 moves, it is pulled by the step axis 16 and the step 2 moves.

  The driven roller 24 is provided rotatably with respect to the support member 23. For example, the driven roller 24 is supported by the support member 23. The driven roller 24 rolls on the upward surface of the rail 19. The movement of step 2 is guided by the driven roller 24 rolling on the rail 19 and the drive roller 20 rolling on the rail 18.

  A gap 25 is formed between the tread 21 and the skirt guard 17. Clothes such as a skirt can easily enter the gap 25. In order to prevent foreign matter such as clothing from entering the gap 25, step 2 further includes a blower 26 in addition to the above basic configuration. The blower 26 is disposed below the tread plate 21. The blower 26 is supported by, for example, the support member 23.

  FIG. 5 is a view showing an example of the blower 26. As shown in FIG. FIG. 5 shows an example in which the driven roller 24 includes the rotating body 27 and the shaft 28. The rotating body 27 contacts the rail 19. The rotating body 27 is fixed to the shaft 28. The shaft 28 rotates with the rotating body 27. The driven roller 24 is provided on the support member 23 via a bearing 29, for example.

  The blower 26 includes, for example, a fan 30 and an interlock 31. The fan 30 is a device for blowing air into the gap 25 from below. The fan 30 is provided, for example, on the support member 23. The fan 30 may be provided on the tread 21.

  The interlocking device 31 is a device for interlocking the fan 30 with the driven roller 24. The interlock device 31 rotates the fan 30 by rotation of the driven roller 24. By the function of the interlocking device 31, the air can be sent to the gap 25 when the driven roller 24 rotates.

  FIG. 5 shows an example in which the interlocking device 31 includes a bevel gear 32, a bevel gear 33, a bevel gear 34, a bevel gear 35, a shaft 36 and a shaft 37. At the end of the shaft 28 a bevel gear 32 is provided. A bevel gear 33 is provided at one end of the shaft 36. The bevel gear 33 meshes with the bevel gear 32. Thereby, when the shaft 28 rotates, the shaft 36 rotates. At the other end of the shaft 36 a bevel gear 34 is provided. A bevel gear 35 is provided at one end of the shaft 37. The bevel gear 35 meshes with the bevel gear 34. Thus, when the shaft 36 rotates, the shaft 37 rotates. For example, the fan 30 is provided on the shaft 37. The fan 30 rotates as the shaft 37 rotates.

  In the example shown in the present embodiment, when the driven roller 24 rotates, the air from the fan 30 is sent to the gap 25. The wind sent from the fan 30 can prevent foreign matter such as a skirt from entering the gap 25. For this reason, in the case of the man conveyor shown in the present embodiment, the foreign matter can be prevented from being caught between Step 2 and the skirt guard 17.

  In order to prevent foreign matter such as a skirt from entering the gap 25, it is necessary to send a wind from below to the gap 25. When the wind from the fan 30 is sent directly to the gap 25, the fan 30 may be disposed upward or obliquely upward. The air may be sent to the gap 25 by disposing the fan 30 obliquely upward and applying a wind from the fan 30 to the skirt guard 17 at an angle.

  FIG. 6 is a view showing another example of the blower 26. As shown in FIG. In the example shown in FIG. 6, the blower 26 further includes a guide member 38 in addition to the fan 30 and the interlocking device 31. The guide member 38 is a member for guiding the wind from the fan 30 to the gap 25. FIG. 6 shows an example in which the guide member 38 has a plate shape. The guide member 38 is disposed closer to the skirt guard 17 than the fan 30, for example. If the wind from the fan 30 can be guided to the gap 25 by the guide member 38, the direction of the fan 30 can be set in consideration of attachment to the support member 23 or the like.

  FIG. 7 is a view showing another example of the blower 26. As shown in FIG. In the example shown in FIG. 7, the blower 26 includes, for example, a cylinder 39, a duct 40 and a compressor 41.

  Compressed air is stored in a cylinder 39. The cylinder 39 is disposed below the tread 21. The cylinder 39 is provided, for example, on the support member 23. The cylinder 39 may be provided on the tread 21. The duct 40 is connected to the cylinder 39. The duct 40 is disposed below the tread 21. The duct 40 extends from the cylinder 39 toward the end of the tread 21. The duct 40 is provided, for example, on the support member 23. The duct 40 may be provided on the tread 21. FIG. 8 is a view showing a tip portion of the duct 40. As shown in FIG. The tip portion of the duct 40 is bent obliquely upward toward the gap 25 as shown, for example, in FIG. Compressed air in the cylinder 39 passes through the duct 40 and is sent to the gap 25 from below.

  The compressor 41 compresses air. The air compressed by the compressor 41 is sent to a cylinder 39. The compressor 41 is driven, for example, by rotation of the shaft 28 of the driven roller 24. That is, as the driven roller 24 rotates, compressed air is sent to the cylinder 39. Also in the example shown in FIG. 7, the air can be sent to the gap 25 when the driven roller 24 rotates. The wind sent from the duct 40 can prevent foreign matter such as a skirt from entering the gap 25. For this reason, in the example shown in FIGS. 6 and 7 as well, the foreign matter can be prevented from being caught between step 2 and the skirt guard 17.

Second Embodiment
In the first embodiment, an example in which the wind is sent to the gap 25 using the rotation of the driven roller 24 has been described. In the example shown in the first embodiment, the wind is sent to the gap 25 even when no foreign matter such as a skirt exists in the gap 25. In the present embodiment, when foreign matter is present in the gap 25, an example will be described in which the wind is sent to the gap 25 before the foreign matter is caught between the step 2 and the skirt guard 17.

  FIG. 9 is a view showing an example of a passenger conveyor according to Embodiment 2 of the present invention. FIG. 9 is a view of step 2 from direction A of FIG. In FIG. 9, a part of the tread 21 is omitted. FIG. 10 is a diagram illustrating an example of step 2. In this embodiment, points different from the example disclosed in Embodiment 1 will be described in detail. In the example shown in the present embodiment, the configuration of the man conveyor other than step 2 is the same as the example disclosed in the first embodiment. Further, the basic configuration of step 2 is the same as the example disclosed in the first embodiment. In FIG. 9, the description of the support member 23 and the driven roller 24 is omitted.

  As described above, the gap 25 is formed between the tread 21 and the skirt guard 17. Clothes such as a skirt can easily enter the gap 25. In order to prevent foreign matter such as clothing and the like which has entered the gap 25 from being caught between the tread plate 21 and the skirt guard 17, step 2 further includes a blower 42 in addition to the basic configuration. The blower 42 is disposed below the tread plate 21. The blower 42 is supported by, for example, the support member 23.

  The blower 42 includes, for example, a cylinder 43, a duct 44, a valve device 45, a controller 46, and a load sensor 47.

  Compressed air is stored in the cylinder 43. The cylinder 43 is disposed below the tread 21. The cylinder 43 is provided, for example, on the support member 23. The cylinder 43 may be provided on the tread 21. The duct 44 is connected to the cylinder 43. The duct 44 is disposed below the tread 21. The duct 44 extends from the cylinder 43 toward the end of the tread 21. The duct 44 is provided, for example, on the support member 23. The duct 44 may be provided on the tread 21.

  The valve device 45 is provided at the tip of the duct 44. If the valve device 45 is open, the compressed air in the cylinder 43 passes through the duct 44 and is sent to the gap 25 from below. If the valve device 45 is closed, the compressed air in the cylinder 43 is not sent to the gap 25. Opening and closing of the valve device 45 is controlled by the controller 46. The controller 46 is disposed below the tread 21. The controller 46 is provided, for example, on the support member 23. The controller 46 may be provided on the tread 21.

  The load sensor 47 is an example of a sensor for detecting the presence of a foreign substance such as clothing which has entered the gap 25. The load sensor 47 is disposed below the tread 21 so as to face the skirt guard 17. The load sensor 47 detects the presence of foreign matter in the gap 25 by detecting a load equal to or greater than a reference value. The reference value is set in advance. The controller 46 outputs an open signal to the valve device 45 when the load sensor 47 detects the presence of foreign matter. The valve device 45 is opened for a fixed time by receiving an open signal from the controller 46. As a result, the compressed air in the cylinder 43 is blown to the gap 25 from below. The blower 42 may include a guide member having the same function as the guide member 38.

  The man conveyor includes, for example, a sensor 48 that detects the displacement of the skirt guard 17. The controller 7 stops the operation when the displacement above the reference value is detected by the sensor 48. For example, the controller 7 stops step 2 when a displacement equal to or greater than the reference value is detected by the sensor 48. The reference value is set in advance. The load sensor 47 of the blower 42 detects, for example, the presence of foreign matter in the gap 25 before the displacement above the reference value is detected by the sensor 48. This function of the load sensor 47 is realized, for example, by setting the above-mentioned reference value at which the load sensor 47 detects the presence of foreign matter.

  FIG. 11 is a view showing another example of the blower 42. As shown in FIG. 12 and 13 show the details of the blower 42. FIG. FIG. 13 is a view of step 2 in the direction of arrows B-B in FIG. In FIGS. 11 to 13, the description of the support member 23 and the driven roller 24 is omitted. 11 to 13 show an example in which the blower 42 does not have an electrical device. In the example shown in FIGS. 11 to 13, the blower 42 includes, for example, a cylinder 43, a duct 44, a valve device 49 and a movable body 50.

  Compressed air is stored in the cylinder 43. The cylinder 43 is disposed below the tread 21. The cylinder 43 is provided, for example, on the support member 23. The duct 44 is connected to the cylinder 43. The duct 44 is disposed below the tread 21. The duct 44 extends from the cylinder 43 toward the end of the tread 21.

  The valve device 49 opens and closes the opening formed at the tip of the duct 44. If the opening formed at the tip of the duct 44 is not blocked by the valve device 49, the compressed air in the cylinder 43 passes through the duct 44 and is sent from below to the gap 25. When the opening formed at the tip of the duct 44 is closed by the valve device 49, the compressed air in the cylinder 43 is not sent to the gap 25.

  The movable body 50 is displaced in a specific direction by the contact of the foreign matter which has entered the gap 25. When the movable body 50 is displaced in the specific direction, the compressed air in the cylinder 43 is sprayed from below to the gap 25 from the valve device 49. In the example shown in FIG. 11 to FIG. 13, the movable body 50 is plate-shaped. The movable body 50 is disposed to face the skirt guard 17. The movable body 50 is provided slidably at the edge of the tread 21 with respect to the tread 21, for example. The movable body 50 slides relative to the tread 21 in a direction along the surface of the opposing skirt guard 17.

  For example, when foreign matter such as clothing enters the gap 25, the foreign matter contacts the movable body 50 and the skirt guard 17. The movable body 50 is pushed by the foreign matter that has entered the gap 25, and slides in the direction opposite to the moving direction of the tread plate 21 with respect to the horizontal projection plane tread plate 21. For example, if the tread plate 21 is moved in the direction indicated by arrow C in FIG. 13, the foreign object contacts the movable body 50, whereby the movable body 50 moves in the direction indicated by arrow D with respect to the tread plate 21.

  The valve device 49 is provided integrally with the movable body 50, for example. When the movable body 50 moves in the direction indicated by the arrow D with respect to the step board 21, the valve device 49 also moves in the direction indicated by the arrow D with respect to the step board 21. An opening 49 a is formed in the valve device 49. Before the movable body 50 moves in the direction indicated by the arrow D, the opening 49 a does not face the opening formed at the tip of the duct 44. The opening formed at the tip of the duct 44 is closed by the valve device 49. When the movable body 50 moves in the direction shown by the arrow D, the opening 49 a communicates with the opening formed at the tip of the duct 44. Thereby, the compressed air in the cylinder 43 is blown out from the valve device 49. The tip portion of the duct 44 is bent obliquely upward toward the gap 25 as shown, for example, in FIG. The opening 49 a is formed obliquely so as to be able to be disposed in line with the end portion of the duct 44. Therefore, the air blown out from the valve device 49 is blown to the gap 25 from below.

  Also in the examples shown in FIGS. 11 to 13, the blower 42 may be provided with a guide having the same function as the guide 38. When the man-made conveyor includes the sensor 48, the movable body 50 is preferably displaced in the direction indicated by the arrow D with respect to the tread plate 21 before the displacement greater than the reference value is detected by the sensor 48.

  In the present embodiment, an example in which the valve device 49 is integrally provided to the movable body 50 has been described. The movable body 50 may be displaced so as to rotate around an axis by, for example, contact with a foreign matter which has entered the gap 25. In such a case, when the movable body 50 is rotated about the axis by a predetermined angle or more, the compressed air in the cylinder 43 is sprayed from the valve device 49 to the gap 25.

  FIG. 14 is a diagram showing a hardware configuration of the control device 7. The control device 7 includes processing circuitry including, for example, a processor 51 and a memory 52 as hardware resources. The control device 7 implements the above-described functions by causing the processor 51 to execute the program stored in the memory 52. Some or all of the functions of the control device 7 may be realized by hardware.

  The hardware configuration of the controller 46 is the same as the example shown in FIG. The controller 46 includes processing circuitry including, for example, a processor and a memory as hardware resources. The controller 46 implements the above-described functions by causing the processor to execute the program stored in the memory. Some or all of the functions of the controller 46 may be implemented by hardware.
