Description

  The present invention relates to a moving handrail used in a man conveyor and a man handrail for use on a man conveyor.

  In a man conveyor such as an escalator or a moving sidewalk, an endless moving handrail having a C-shaped cross section is generally used. The moving handrail is for a passenger on the step to hold it for safety. The moving handrail is driven to synchronize with the steps, and its travel is guided by the guide rail.

  In the man conveyor, the driving of the moving handrail and the traveling guidance are generally performed via the inner surface of the moving handrail. For this reason, the moving handrail has a high friction characteristic (friction coefficient) for generating sufficient driving force on its inner surface and a low friction characteristic (friction coefficient) for reducing resistance during travel (travel resistance). ) And both functions are required.

  Patent Document 1 discloses a conventional technique of a moving handrail of a man conveyor. In the moving handrail described in Patent Document 1, a yarn having extremely low friction characteristics such as a fluororesin fiber is used for a part of the warp yarn constituting the canvas. The canvas is woven so that the warp passes through the front side more than the back side of the weft.

Embodiment 1 FIG.
FIG. 1 is a side view showing the overall configuration of the man conveyor. Below, the structure of the escalator utilized in the case of the movement between an upper and lower floor is demonstrated concretely. The description of other examples of the man conveyor, for example, the configuration of a moving sidewalk, is omitted.

  In FIG. 1, reference numeral 1 denotes an escalator truss spanned between upper and lower floors. The truss 1 supports the escalator's own weight and load capacity. 2 is a step on which the passenger rides when moving between the upper and lower floors. The step 2 is connected to an endless step chain 3. The step chain 3 is wound around a step drive sprocket 5 in a machine room 4 provided in the upper part of the truss 1.

  6 is a drive motor, and 7 is a speed reducer. The drive motor 6 is for driving the step drive sprocket 5 and the like. The speed reducer 7 decelerates the output of the drive motor 6 and rotates the shaft provided with the step drive sprocket 5 via the chain. A control panel 8 controls the operation of the escalator. The drive motor 6 is controlled by the control panel 8.

  Reference numeral 9 denotes an endless moving handrail. The moving handrail 9 is gripped by a passenger who gets on and off the step 2 or a passenger on the step 2 for safety. A balustrade 10 is provided on both sides of the step 2. The upper side of the moving handrail 9 is arranged along the upper end of the balustrade 10. Further, the moving handrail 9 is inverted up and down at the upper and lower entrances of the escalator, and the lower side is disposed in a skirt guard or the like provided on both sides of the step 2.

  The moving handrail 9 is driven by the handrail driving device 11 so as to be synchronized with the step 2 on the forward path side. The handrail drive device 11 drives the moving handrail 9 by, for example, a friction drive method. A handrail drive device 11 that employs a friction drive system is provided with a drive roller 12 and a pressure roller 13 (both not shown in FIG. 1). The moving handrail 9 is sandwiched from above and below (front and back) by the drive roller 12 and the pressure roller 13.

The driving roller 12 contacts the inner surface of the moving handrail 9. The pressure roller 13 is in contact with the outer surface of the moving handrail 9 (the surface gripped by the passenger (gripping surface)).

  Reference numeral 14 denotes a handrail drive sprocket. The handrail driving sprocket 14 is provided on the same shaft as the step driving sprocket 5. The rotational force of the handrail drive sprocket 14 is transmitted to the handrail drive device 11 by the handrail chain 15. That is, the handrail driving sprocket 14 is rotated together with the step driving sprocket 5 by the driving force of the driving motor 6, and the driving force is transmitted to the handrail driving device 11 through the handrail chain 15. The moving handrail 9 is driven by the handrail driving device 11 and circulates between the upper and lower floors in synchronization with the step 2 on the forward path side.

FIG. 2 is a cross-sectional view taken along line AA shown in FIG. 3 is a cross-sectional view taken along line BB shown in FIG. FIG. 4 is a cross-sectional view showing the moving handrail of the man conveyor in the first embodiment of the present invention.

  The moving handrail 9 has a substantially C-shaped cross section (short direction). The driving of the moving handrail 9 by the handrail driving device 11 and the traveling guidance of the moving handrail 9 by the guide rail 16 are performed via the inner surface of the moving handrail 9. For this reason, the moving handrail 9 has a high friction characteristic (friction coefficient) for generating a sufficient driving force on the inner surface and a resistance (travel resistance) for traveling on the guide rail 16. Both functions with low friction properties (friction coefficient) are required.

The main part of the moving handrail 9 in the present embodiment is constituted by the main body resin portion 17, the tensile body 18, and the canvas 19.
The main body resin part 17 constitutes a main part of the moving handrail 9. The main body resin portion 17 has a substantially C-shaped cross section and is formed endlessly as a whole. The main body resin portion 17 is made of a resin member such as rubber or polyurethane, for example. In FIG. 2 etc., the case where the main body resin part 17 consists of one kind of resin member is shown as an example. The main body resin portion 17 may be composed of a plurality of resin layers in accordance with the function to be given to the moving handrail 9 or the like.

  The tensile body 18 is for imparting a predetermined tensile strength to the moving handrail 9 and preventing its elongation. The tensile body 18 is made of, for example, a wire made of steel. The tensile body 18 may be made of steel tape or the like. The tensile body 18 is provided inside the main body resin portion 17 along the length thereof.

  The canvas 19 is provided to give both functions of the above-described friction characteristics to the moving handrail 9. The canvas 19 is provided on the inner surface of the main body resin portion 17 along the length of the main body resin portion 17. FIG. 5 is a front view showing the canvas of the moving handrail according to the first embodiment of the present invention. 6 is a cross-sectional view of the canvas shown in FIG.

The canvas 19 has a two-layer structure including a base cloth 20 and a sliding cloth 21.
The base fabric 20 is provided on the inner surface of the main body resin portion 17 along the length of the main body resin portion 17. The base fabric 20 is disposed so as to cover the entire inner surface of the main body resin portion 17. For the base fabric 20, at least a part thereof is made of a fiber excellent in adhesiveness with the resin constituting the inner surface of the main body resin portion 17. FIG. 7 is a diagram showing an example of the weaving method of the base fabric shown in FIG. 5, and FIG. 8 is a diagram showing another example of the weaving method of the base fabric.

  The base fabric 20 is made of, for example, a woven fabric in which warp yarns 22 and weft yarns 23a are woven in a predetermined weaving method. The warp yarn 22 is a yarn whose length is arranged along the length of the main body resin portion 17 (moving handrail 9). The weft thread 23a is a thread whose length is arranged along the short side (direction perpendicular to the length) of the main body resin portion 17. For example, polyester fiber is used as the warp yarn 22 and the weft yarn 23a.

  In the weaving method shown in FIG. 7, each warp yarn 22 passes through the surface side of one weft thread 23 a (the side that partially forms the inner surface of the moving handrail 9) and then the back surface side of one weft thread 23 a ( Passes through the side facing the main body resin portion 17. That is, each warp 22 passes alternately on the front side and the back side of the weft 23a. Each weft 23 a passes through the front side of one warp 22 and then passes through the back side of one warp 22. That is, each weft 23a passes alternately on the front side and the back side of the warp yarn 22.

  In the weaving method shown in FIG. 8, each warp 22 passes through the front side of one weft 23a and then passes through the back side of one weft 23a. That is, each warp 22 passes alternately on the front side and the back side of the weft 23a.

There are two types of passing methods for the warp yarn 22 in the weft yarn 23a. The first type of weft 23 a passes through the front side of one warp 22 and then passes continuously through the back side of the two warps 22. The first type weft 23a repeats this passage. The second type of weft 23 a passes through the back side of one warp 22 and then passes continuously through the front side of the two warps 22. The second type weft 23a repeats this passage. The first-type wefts 23a and the second-type wefts 23a are alternately arranged.
The weaving method of the base fabric 20 is not limited to the method shown in FIGS.

  The sliding cloth 21 is provided to reduce resistance (traveling resistance) when the moving handrail 9 travels on the guide rail 16. The sliding cloth 21 is provided on the base cloth 20 so as to cover a part of the surface of the base cloth 20. The sliding cloth 21 is not disposed at a portion where the driving roller 12 faces. In the present embodiment, the drive roller 12 contacts (opposes) the central portion of the canvas 19. For this reason, the sliding cloth 21 is disposed on both sides of the canvas 19, avoiding the central part. That is, in the moving handrail 9, the two sliding cloths 21 are arranged along the length of the main body resin portion 17. Further, the surface of the base fabric 20 is exposed along the length of the main body resin portion 17 between the one sliding fabric 21 and the other sliding fabric 21.

  At least a part of the sliding cloth 21 is a fiber having a friction characteristic lower than that of the fiber constituting the base cloth 20, and a predetermined fiber that is more easily worn than the fiber constituting the base cloth 20 is used. It is done. FIG. 9 is a diagram showing an example of how the sliding cloth shown in FIG. 5 is woven. FIG. 10 is a diagram showing another example of how the sliding cloth is woven.

  The sliding cloth 21 is made of a woven fabric in which warp yarns 24 and weft yarns 23b are woven in a predetermined weaving manner, for example. The warp yarn 24 is a yarn having a length arranged along the length of the main body resin portion 17 (moving handrail 9). The warp yarns 24 are made of predetermined fibers that have lower frictional properties than the fibers that make up the base fabric 20 and are easy to wear. As the warp 24, for example, a fluororesin fiber (PTFE material) is used.

  The weft thread 23b is a thread whose length is arranged along the short side (direction perpendicular to the length) of the main body resin portion 17. For example, a polyester fiber is used as the weft 23b. In the present embodiment, as an example, a case where a common weft is used for the base fabric 20 and the sliding fabric 21 is shown.

  In the weaving method shown in FIG. 9, each warp thread 24 passes through the surface side of one weft thread 23b (the side forming the inner surface of the moving handrail 9) and then the back surface side (base fabric 20) of the four weft threads 23b. Pass continuously). The warp yarn 24 repeats this passage. Each weft 23 b passes through the back side of one warp 24 and then passes continuously through the front side of the four warps 24. The weft 23b repeats this passage.

  In the weaving method shown in FIG. 10, each warp yarn 24 passes through the front surface side of one weft yarn 23b and then passes continuously through the back surface side of nine weft yarns 23b. The warp yarn 24 repeats this passage. In the weft 23b, there are two types of passing methods for the warp 24. The first type of weft thread 23 b passes through the back side of one warp thread 24 and then continuously passes through the surface side of the four warp threads 24. The first type weft 23b repeats this passage. The second type of weft thread 23b passes only on the surface side of the warp thread 24. The first type wefts 23b and the second type wefts 23b are alternately arranged.

  The weaving method of the sliding cloth 21 is not limited to the method shown in FIGS. However, as a weaving method of the sliding cloth 21, it is necessary to satisfy the following conditions I and II.

I) The warp yarn 24 periodically passes the surface side of the weft yarn 23b.
The sliding fabric 21 shown in FIGS. 9 and 10 is woven so that each warp yarn 24 periodically passes the surface side of the weft yarn 23b. That is, the warp yarn 24 that passes only the back side of the weft yarn 23b does not exist in the sliding cloth 21 shown in FIGS.

II) The exposed portions 24 a of the warp yarns 24 are not adjacent to each other on the surface of the sliding cloth 21.
FIG. 11 is an enlarged view of part C shown in FIG. The exposed portion 24 a of the warp yarn 24 is a portion where the warp yarn 24 is exposed on the surface of the sliding cloth 21 when the warp yarn 24 passes the surface side of the weft yarn 23 b. When the warp yarn 24 passes the back side of the weft yarn 23b, the portion where the warp yarn 24 is not exposed on the surface of the sliding cloth 21 is referred to as the non-exposed portion 24b with respect to the exposed portion 24a. The periphery (in FIG. 11, the top, bottom, left, right, upper right, lower right, upper left, lower left) is surrounded by the non-exposed portion 24b.

  FIG. 12 is a diagram for explaining the configuration of the canvas of the moving handrail according to the first embodiment of the present invention. The entanglement thread 25 shown in FIG. 12 is a thread for fixing the sliding cloth 21 to the surface side of the base cloth 20. The entangled yarn 25 is woven so as to be entangled with the fibers constituting the base fabric 20 and the fibers constituting the sliding fabric 21. In the present embodiment, the entangled yarn 25 is arranged in the same direction as the warp yarns 22 and 24, and the back surface side of the weft yarn 23a of the base fabric 20 and the front surface side of the weft yarn 23b of the sliding fabric 21 are alternately passed. .

  The moving handrail 9 having the above configuration is driven by the handrail driving device 11 and moves (runs) along the guide rail 16. When the moving handrail 9 is traveling, only the sliding cloth 21 is in contact with the guide rail 16, and the base cloth 20 is not in contact with the guide rail 16. When the sliding cloth 21 comes into contact with the guide rail 16, the warp 24 of the sliding cloth 21 gradually wears, and the wear powder (material component of the warp 24) is the entire surface of the guide rail 16 and the sliding cloth 21. It adheres to (the surface of the weft 23b). Thereby, the surface of the sliding cloth 21 is coated with the material component of the warp yarn 24.

  Since the surface of the sliding cloth 21 is coated with the material component of the warp yarn 24, the resistance (traveling resistance) when the moving handrail 9 travels on the guide rail 16 is greatly reduced. Since each of the warp yarns 24 is exposed on the surface of the sliding cloth 21, the entire surface of the sliding cloth 21 can be uniformly coated with the material components of the warp yarns 24 by moving the moving handrail 9 to the longitudinal direction. .

  The warp yarns 24 of the sliding cloth 21 are gradually worn by contacting the guide rails 16. When the exposed portion 24a is arranged at a position close to the surface of the sliding cloth 21, the warp thread 24 is likely to jump out of the sliding cloth 21 when the wear of the warp thread 24 proceeds to some extent. The sliding cloth 21 in the present embodiment is woven so that the exposed portions 24 a of the warp yarns 24 are not adjacent to each other on the surface of the sliding cloth 21. For this reason, even if the warp yarn 24 is worn, the warp yarn 24 can be appropriately held, and a problem that the warp yarn 24 jumps out of the sliding cloth 21 can be reliably prevented.

  In order to prevent such a problem, the exposed portion 24a is disposed at a position close to the surface of the sliding cloth 21, and the exposed portion 24a is placed on the surface of the sliding cloth 21 on the same weft 23b. It is necessary to avoid appearing frequently. FIG. 9 shows a weaving method of the sliding cloth 21 when such an optimum condition is provided. Specifically, the weaving method of the sliding cloth 21 shown in FIG. 9 satisfies the following condition III in addition to the above conditions I and II.

III) The weft 23b periodically passes the back side of the warp 24.
The sliding cloth 21 shown in FIG. 9 is woven so that each weft 23b periodically passes through the back side of the warp 24. That is, the weft 23b that passes only through the surface side of the warp 24 does not exist in the sliding cloth 21 shown in FIG.

  The weaving method of the sliding cloth 21 shown in FIG. 9 is for the appearance rate of the exposed portion 24a (the portion where the warp yarn 24 and the weft yarn 23b intersect (exposed portion 24a and non-exposed portion 24b) among those satisfying the conditions I to III. The ratio of the exposed portion 24a is maximized. In the sliding cloth 21 shown in FIG. 9, the appearance rate of the exposed portion 24a is 20%. In order to satisfy the above conditions I to III, it is necessary to pass the warp yarn 24 continuously through the back side of four or more wefts 23b after passing the front side of one weft 23b. Moreover, after passing the weft 23b through the back side of one warp 24, it is necessary to continuously pass the surface side of four or more warps 24. In such a case, the appearance rate of the exposed portion 24a is 20% or less (greater than 0%).

  The weave of the sliding cloth 21 shown in FIG. 10 does not satisfy the condition III. In the sliding cloth 21 shown in FIG. 10, a part of the weft 23 b passes only on the surface side of the warp 24. However, the sliding cloth 21 shown in FIG. 10 has a lower appearance rate of the exposed portion 24a than the sliding cloth 21 shown in FIG. In the sliding cloth 21 shown in FIG. 10, the appearance rate of the exposed portion 24a is 10%. For this reason, on the same weft 23b, the interval between the exposed portions 24a can be increased to some extent, and there is no problem even if the condition III is not satisfied.

  In the moving handrail 9 in the present embodiment, the warp yarns 24 of the sliding cloth 21 are actively worn, and the surface of the sliding cloth 21 is coated with the material components. For this reason, it is preferable that the warp yarn 24 of the sliding cloth 21 contacts the guide rail 16 before the weft yarn 23b. For example, the warp yarn 24 is protruded to the surface side from the weft yarn 23b. Such a method can be easily realized by adopting, as the warp yarn 24, a yarn having a diameter larger than that of the weft yarn 23b.

  FIG. 13 is a front view showing the canvas of the moving handrail according to the first embodiment of the present invention. FIG. 13 shows an arrangement example of the exposed portions 24a when the sliding cloth 21 is woven by the weaving method shown in FIG.

  As shown in FIG. 13, when two sliding cloths 21 are provided along the length of the canvas 19, the exposed portion 24 a provided on one sliding cloth 21 and the other sliding cloth 21 are provided. The exposed portion 24a is preferably arranged symmetrically with respect to a line along the length of the moving handrail 9 (canvas 19). With such a configuration, it is possible to prevent the running resistance from being biased due to the arrangement of the exposed portion 24a and to stabilize the running of the moving handrail 9. When the weaving method of the sliding cloth 21 satisfies the above conditions I to III, the exposed portions 24a are arranged in a V shape as a whole on the surface of the sliding cloth 21 as shown by the broken line D in FIG. . A broken line D indicates a line connecting adjacent exposed portions 24a.

  In manufacturing the movable handrail 9, first, a long handrail body having the same configuration as the movable handrail 9 shown in FIG. 4 is manufactured. In the handrail main body, a tensile member 18 and a canvas 19 are provided on a long member (main body resin portion) having the same cross section as the main body resin portion 17. After producing a long handrail main body, the handrail main body is cut into a predetermined length, and both ends thereof are connected to complete the endless moving handrail 9.

  In the present embodiment, the case where the canvas 19 is constituted by the base cloth 20 and the sliding cloth 21 has been described in order to give both functions of the above-described friction characteristics to the moving handrail 9. However, this is just an example. The canvas 19 may be composed of any number of layers (including one layer) as long as both of the above functions can be realized.

That is, the canvas 19 is provided with a base portion and a sliding portion.
The base portion forms part of the surface of the canvas 19 along the length of the main body resin portion 17. The base is a portion having a high friction characteristic (friction coefficient) for generating a sufficient driving force for the moving handrail 9, and is disposed so that the driving roller 12 faces (contacts). In the present embodiment, a portion of the base fabric 20 that is exposed along the length of the main body resin portion 17 between the one sliding fabric 21 and the other sliding fabric 21 corresponds to the base portion. Various configurations of the above-described base fabric 20 can be employed as the base.

  The sliding portion forms another part of the surface of the canvas 19 along the length of the main body resin portion 17. The sliding portion is a portion having a low friction characteristic (friction coefficient) for reducing resistance (traveling resistance) when traveling on the guide rail 16, and is disposed so as to face (contact) the guide rail 16. The In the present embodiment, the sliding cloth 21 corresponds to the sliding portion. Various configurations of the above-described sliding cloth 21 can be employed as the sliding portion.

Embodiment 2. FIG.
FIG. 14 is a diagram showing an example of a weaving method of the sliding cloth of the moving handrail according to the second embodiment of the present invention.

  In the weaving method of the sliding cloth 21 shown in FIG. 14, each weft thread 23 b passes through the back side of one warp thread 24, and then continuously passes through the surface side of the five warp threads 24. The weft 23b repeats this passage. The warp yarn 24 has two types of passing methods for the weft yarn 23b. The first type warp yarn 24 passes through the front surface side of one weft yarn 23b, and then continuously passes through the back surface side of the two weft yarns 23b. The first type warp yarn 24 repeats this passage. The second type of warp yarn 24 passes only on the back side of the weft yarn 23b. The first type warp yarns 24 and the second type warp yarns 24 are alternately arranged.

  The weaving method of the sliding cloth 21 shown in FIG. That is, a part of the warp yarn 24 always passes the back side of the weft yarn 23b. If the position in the width direction of the moving handrail 9 relative to the guide rail 16 does not change when the moving handrail 9 travels, the material of the warp 24 is formed on the surface of the portion of the weft 23b where the second type of warp 24 passes the back side. The component does not adhere. However, in an actual man conveyor, the position in the width direction of the moving handrail 9 relative to the guide rail 16 is not always the same. The moving handrail 9 moves on the guide rail 16 while slightly swinging left and right. For this reason, even if the weave of the sliding cloth 21 shown in FIG. 14 (for example, the weaving satisfying only Condition II), the entire surface of the sliding cloth 21 is coated with the material components of the warp yarn 24. Even if the above condition I is not satisfied, a certain effect can be expected.

  Other configurations are the same as the configurations disclosed in the first embodiment.
