Description

[Technical Field]

[0001] The present invention relates to a passenger conveyor repair method and a moving handrail repair tool. [Background technology]

[0002] Passenger conveyors such as escalators and moving walkways are equipped with steps and moving handrails. The steps and moving handrails move at the same speed and in the same direction. The moving handrails are equipped with a handrail body with a horseshoe-shaped (approximately C-shaped) cross section and canvas covering the inner surface of the handrail body. The moving handrails are wound around a drive pulley and move as the drive pulley rotates. The moving handrails are also attached to handrail guides and move along the handrail guides.

[0003] When the passenger conveyor is in operation, the moving handrail moves cyclically due to frictional forces generated at the contact points between the drive pulley and the moving handrail. For this reason, as the passenger conveyor is used for a long period of time, the canvas that comes into contact with the drive pulley and the handrail guide gradually wears out. As the canvas wears out, parts of the canvas wear away, exposing the inner surface of the handrail body. The inner surface of the handrail body is made of a high-friction material such as urethane rubber. Therefore, if the canvas wears out and the inner surface of the handrail body comes into direct contact with the drive pulley or the handrail guide, the friction between the handrail body and the handrail guide, etc., can easily cause abnormal noise.

[0004] Patent Document 1 describes a technique for repairing a portion of the canvas that has peeled off due to wear (hereinafter referred to as a "peeled portion of the canvas") by filling the portion with adhesive. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-250969 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology described in Patent Document 1 is a repair method that simply fills the peeled-off canvas area with adhesive, so when the passenger conveyor is restarted after repair, the adhesive filled in the peeled-off canvas area comes into direct contact with the handrail guide, etc. Therefore, if the adhesive has high friction, it is likely to rub against the handrail guide and cause abnormal noise.

[0007] An object of the present invention is to provide a technique that can suppress the generation of abnormal noise after repair when repairing damaged portions of canvas in a moving handrail. [Means for solving the problem]

[0008] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes a number of means for solving the above-mentioned problems. One of the means is a method for repairing a passenger conveyor equipped with a moving handrail having canvas, which includes a step of grinding a damaged portion of the canvas of the moving handrail into a concave shape. After the damaged area is scraped, nothing is covered over the damaged area. . [Effects of the Invention]

[0009] According to the present invention, when repairing a damaged portion of canvas in a moving handrail, the generation of abnormal noise after repair can be suppressed. Problems, configurations, and effects other than those described above will become apparent from the following description of the embodiments. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are designated by the same reference numerals, and redundant description will be omitted.

[0012] FIG. 1 is a schematic side view showing the configuration of an escalator according to this embodiment. As shown in Fig. 1, escalator 1 comprises a plurality of steps 2 connected endlessly, balustrades 3 arranged on the left and right of steps 2, and a moving handrail 4 that moves on balustrade 3. Steps 2 and moving handrail 4 move in the same direction at the same speed. Note that in this embodiment, an escalator is given as an example of a passenger conveyor, but the passenger conveyor is not limited to an escalator and may be, for example, a moving walkway.

[0013] As shown in Figure 2, the movable handrail 4 is detachably attached to the handrail guide 5. The handrail guide 5 is provided at the upper end of the balustrade 3. The handrail guide 5 guides the movement of the movable handrail 4. The movable handrail 4 is configured so that it does not come off the handrail guide 5 while moving along it. A balustrade light 6 is arranged below the handrail guide 5.

[0014] As shown in FIG. 3, the moving handrail 4 comprises a handrail main body 40 with a horseshoe-shaped (approximately C-shaped) cross section, and canvas 10 covering the inner surface of the handrail main body 40. The handrail main body 40 comprises an outer decorative resin portion 7, a core material 8 formed inside the decorative resin portion 7, and a plurality of steel cords 9 embedded inside the core material 8. The decorative resin portion 7 is formed to cover the outer surface of the core material 8. The core material 8 is made of, for example, a rubber material. The inner surface of the core material 8 is covered with canvas 10. The steel cords 9 are tensile members that ensure the tensile strength of the moving handrail 4. The tensile members are not limited to steel cords 9, and may be made of, for example, steel tape or the like.

[0015] The canvas 10 is a sliding material that serves to reduce the friction between the moving handrail 4 and the handrail guide 5 when the moving handrail 4 moves along the handrail guide 5. The canvas 10 is formed integrally with the decorative resin part 7 and the core material 8.

[0016] The moving handrail 4 configured as described above is wound around a drive pulley (not shown) provided on the escalator 1. The moving handrail 4 then moves in a circular motion in accordance with the rotation of the drive pulley due to friction with the drive pulley. During this movement, the canvas 10 of the moving handrail 4 moves while in contact with the drive pulley and the handrail guide 5. For this reason, when the escalator 1 is used for a long period of time, the surface of the canvas 10 that comes into contact with the drive pulley and the handrail guide 5 wears away. As the canvas 10 wears away and peels off or wears away, the underlying core material 8 becomes exposed. The core material 8 has a higher frictional resistance than the canvas 10. For this reason, during the circular movement of the moving handrail 4, the core material 8 that is exposed due to the wear of the canvas 10 rubs against the drive pulley and the handrail guide 5, making it more likely to generate abnormal noise. Therefore, in this embodiment, the escalator 1 is repaired using the following method.

[0017] FIG. 4 is a flowchart showing the escalator repair method according to this embodiment. In the following description, a portion of the canvas 10 that has peeled off or worn away due to wear or the like of the canvas 10 will be collectively referred to as a damaged portion of the canvas 10. However, in this embodiment, the cause of the damage to the canvas 10 is not important. Also, as shown in FIG. 3, damaged portions 12 of the canvas 10 in the moving handrail 4 are likely to occur inside the ear portions 11 of the moving handrail 4 (particularly the rounded portions on the lower side). The ear portions 11 are portions that constitute part of the moving handrail 4 and are formed on both sides in the width direction X of the moving handrail 4. The ear portions 11 are also formed with a horizontal U-shaped cross section. The escalator repair method according to this embodiment is a suitable method to apply when repairing damaged portions 12 of the canvas 10 that have occurred on the ear portions 11 of the moving handrail 4.

[0018] First, the worker in charge of repairing the escalator 1 visually or otherwise checks the location of the damaged portion 12 on the canvas 10, and then turns the power of the escalator 1 on and off to move the damaged portion 12 to a position suitable for repairing the canvas 10 (Step S1). The position suitable for repairing is a position where it is easy to turn up the moving handrail 4, and specifically, the middle position of the straight portion of the escalator 1 as shown in Figure 1 (position P in the figure or a position close to this).

[0019] Next, the worker determines whether the repair cannot be made without removing the moving handrail 4 from the handrail guide 5 (Step S2). At this time, the worker loosens the tension on the moving handrail 4 so that it is easier to visually check the inside of the moving handrail 4. Then, if the worker determines that the repair cannot be made without removing the moving handrail 4 from the handrail guide 5, he or she removes the moving handrail 4 from the handrail guide 5 (Step S3). Whether or not it is necessary to remove the moving handrail 4 from the handrail guide 5 can be determined based on the size of the damaged portion 12 of the canvas 10.

[0020] Next, the worker measures the size and depth of the damaged area 12 of the canvas 10 shown in Figure 5 (Step S4). This measurement can be performed using, for example, a ruler or a depth measuring gauge. The size of the damaged area 12 is defined by the length of the damaged area 12 in the longitudinal direction of the moving handrail 4.

[0021] Next, the worker checks whether the depth of the damaged area 12 is smaller than the thickness of the repair canvas 13 (Fig. 6) (Step S5). If the depth of the damaged area 12 is smaller than the thickness of the repair canvas 13, and the repair canvas 13 is simply adhered to the damaged area 12, the peripheral edge 14 of the repair canvas 13 will protrude from the surface 10a of the existing canvas 10, as shown in Fig. 6. For this reason, when the moving handrail 4 is circulated after repair, the peripheral edge 14 of the repair canvas 13 will come into contact with the handrail guide 5 and the drive pulley, making the repair canvas 13 more likely to peel off.

[0022] Therefore, if the depth of the damaged area 12 is smaller than the thickness of the repair canvas 13, the damaged area 12 of the canvas 10 is cut into a concave shape by a predetermined cutting allowance 15, as shown in FIG. 7 (step S6). In this specification, cutting the damaged area 12 into a concave shape means cutting the damaged area 12 so that the surface 12b of the damaged area 12 after cutting is recessed compared to the surface 12a of the damaged area 12 before cutting. Therefore, the thickness of the moving handrail 4 at the location where the damaged area 12 has been cut away is reduced by the cutting allowance 15. In step S6, the worker cuts the damaged area 12 so that the depth of the damaged area 12 is equal to or slightly deeper than the thickness of the repair canvas 13. In other words, the worker cuts the damaged area 12 so that the depth of the damaged area 12 is equal to or less than the thickness of the repair canvas 13. Possible methods for scraping the damaged portion 12 include, for example, using sandpaper or a hand grinder.

[0023] By scraping the damaged portion 12 in this way, the thickness dimension of the moving handrail 4 (core material 8) at the damaged portion 12 of the canvas 10 is reduced by the scraping allowance 15. The predetermined scraping allowance 15 is a dimension that prevents the repair canvas 13 from protruding from the surface 10a of the existing canvas 10 when the repair canvas 13 is adhered to the damaged portion 12 of the canvas 10 in step S9 described below, as shown in FIG.

[0024] Thereafter, the worker cleans the damaged portion 12 scraped off in step S6 (step S7). The work of cleaning the damaged portion 12 includes at least one of the following tasks: cutting off the canvas 10 that has peeled off or worn away due to wear; removing shavings from the core material 8; and cleaning the damaged portion 12 after scraping with a degreasing spray or the like.

[0025] Next, the worker cuts out the repair canvas 13 to a size slightly smaller than the size of the damaged area 12 (step S8). At this time, the worker cuts out the repair canvas 13 to match the planar shape of the damaged area 12. In addition, the worker cuts out the repair canvas 13 to be, for example, a few millimeters smaller than the size of the damaged area 12 so that the peripheral edge 14 (FIG. 8) of the repair canvas 13 does not protrude from the surface of the existing canvas 10.

[0026] Next, as shown in FIG. 8, the worker applies adhesive to one side of the repair canvas 13 cut out in step S8 and presses this coated surface against the damaged area 12, thereby adhering the repair canvas 13 to the damaged area 12 (step S9). The adhesive may be in the form of a liquid, gel, cream, or spray. By adhering the repair canvas 13 in this manner, when the repair canvas 13 is pressed against the damaged area 12 as described above, the adhesive spreads and blends over the entire coated surface of the repair canvas 13. This results in a good bond between the repair canvas 13 and the damaged area 12.

[0027] Next, the worker presses the repair canvas 13 adhered as described above until it has hardened for a predetermined time (step S10). For example, if the predetermined hardening time is five minutes, the worker keeps the repair canvas 13 pressed against the damaged area 12 for five minutes. This allows the repair canvas 13 to be adhered tightly to the damaged area 12. The hardening time can be set appropriately depending on the adhesive used to adhere the repair canvas 13.

[0028] Finally, the worker returns the moving handrail 4 to its original state (step S11). For example, if the worker removed the moving handrail 4 from the handrail guide 5 in step S3 above, the worker applies a predetermined tension to the moving handrail 4 after attaching the moving handrail 4 to the handrail guide 5. Furthermore, if the worker performed repair work without removing the moving handrail 4 from the handrail guide 5, the worker applies a predetermined tension to the moving handrail 4. The above is the repair method when the canvas 10 of the moving handrail 4 of the escalator 1 is damaged.

[0029] The escalator repair method according to this embodiment includes a step of carving damaged portion 12 of canvas 10 into a concave shape when repairing damaged portion 12 in canvas 10 of moving handrail 4. This prevents the repaired portion of damaged portion 12 from coming into contact with handrail guide 5 or the like when escalator 1 is restarted after repairing damaged portion 12. This makes it possible to prevent abnormal noise from occurring after repair.

[0030] The escalator repair method according to this embodiment also includes a step of adhering repair canvas 13 to damaged portion 12 of canvas 10, which has been scraped into a concave shape. As a result, damaged portion 12 of canvas 10 is covered by repair canvas 13, so that damaged portion 12 is protected by repair canvas 13 while friction in the repaired portion can be kept low.

[0031] Furthermore, in the escalator repair method according to this embodiment, the damaged portion 12 is scraped in step S6 so that when the repair canvas 13 is adhered to the damaged portion 12 of the canvas 10 in step S9, the repair canvas 13 does not protrude from the surface 10a of the existing canvas 10. This prevents the repair canvas 13 adhered to the damaged portion 12 of the canvas 10 from coming into contact with the handrail guide 5 and the like.

[0032] Furthermore, in the escalator repair method according to this embodiment, repair canvas 13 is used that is one size smaller than damaged portion 12 of canvas 10. This makes it possible to prevent repair canvas 13 from protruding from damaged portion 12 when repair canvas 13 is adhered to damaged portion 12.

[0033] Furthermore, in the escalator repair method according to this embodiment, damaged portion 12 is scraped so that the depth of damaged portion 12 is equal to or less than the thickness of repair canvas 13. As a result, as shown in Figure 8, when repair canvas 13 is adhered to damaged portion 12, surface 13a of repair canvas 13 can be positioned flush with surface 10a of existing canvas 10 or recessed relative to surface 10a of canvas 10. This prevents repair canvas 13 adhered to damaged portion 12 of canvas 10 from coming into contact with handrail guide 5 and the like.

[0034] In the above embodiment, the repair canvas 13 is adhered to the damaged portion 12 using an adhesive, but the method for adhering the repair canvas 13 is not limited to this. For example, the repair canvas 13 may be adhered using adhesive tape that matches the size of the repair canvas 13. The adhesive tape used is adhesive tape that is adhesive on both sides. With this method, the desired adhesive strength is obtained simply by pressing the repair canvas 13 against the damaged area 12 with the adhesive tape, so no curing time is required. This makes it possible to efficiently repair the moving handrail 4. Another advantage is that the worker's hands are less likely to get dirty.

[0035] Alternatively, the repair canvas 13 may be adhered to the damaged area 12 by heat welding. Specifically, heat is applied to the repair canvas 13 placed over the damaged area 12, and the repair canvas 13 is heat-welded to the core material 8 underlying the damaged area 12. This method makes it possible to obtain a high adhesive strength between the damaged area 12 and the repair canvas 13.

[0036] Furthermore, in the above embodiment, the damaged portion 12 is scraped in step S6, and then the repair canvas 13 is adhered to the damaged portion 12 in step S9. However, this is not limited to this, and the scraped damaged portion 12 does not have to be covered with anything. In other words, the damaged portion 12 may be left exposed after scraping. In this case, the damaged portion 12 should be scraped deep enough so that the core material 8 forming the surface of the damaged portion 12 does not come into contact with the handrail guide 5 or the drive pulley. In this way, if the damaged portion 12 is not covered with anything after scraping, the steps (S8 to S10) of adhering the repair canvas 13 to the damaged portion 12 can be omitted. This significantly reduces the time required to repair the moving handrail 4.

[0037] After the damaged area 12 is scraped in step S6, it is preferable to clean the damaged area 12 in step S7. This allows the repair canvas 13 to be adhered to the damaged area 12 without any shavings or other debris getting between the damaged area 12 and the repair canvas 13. This ensures a good bond.

[0038] Next, a repair tool for a moving handrail according to this embodiment (hereinafter simply referred to as a "repair tool") will be described. The repair tool according to this embodiment is suitable for use when carrying out the escalator repair method described above. However, the handrail repair tool according to this embodiment can also be used when carrying out methods other than the escalator repair method described above. Furthermore, as shown in FIG. 3, the maintenance tool according to this embodiment is used when a damaged section 12 occurs inside the ear 11 of the handrail 4. The inside of the ear 11 is narrow. For this reason, it is difficult to fit the repair canvas 13 tightly to the damaged section 12. In such cases, it is preferable to use the repair tool described below.

[0039] FIG. 9 is a perspective view showing an example of the configuration of a repair tool for a moving handrail according to this embodiment. As shown in FIG. 9, a repair tool 100 for a moving handrail includes a pair of holding portions 101 and a movement adjustment portion 102 that connects the pair of holding portions 101.

[0040] Each of the pair of pressing portions 101 is formed in a rod shape. The pair of pressing portions 101 are arranged parallel to and facing each other. Each pressing portion 101 is formed with a D-shaped cross section so that it is the same shape as the ear portion 11 or a slightly larger shape. Each pressing portion 101 also has a pressing surface 101a for pressing the inner surface of the ear portion 11. The pressing surface 101a is formed with a horizontal U-shaped cross section so that it fits the shape of the ear portion 11 of the moving handrail 4.

[0041] The movement adjustment unit 102 is a member that can move the pair of holding units 101 in a direction to move them closer to or away from each other. The movement adjustment unit 102 is configured by, for example, a turnbuckle. As shown in FIG. 10, the movement adjustment unit 102 includes a rotatable operating unit 102a and a pair of expansion / contraction units 102b. The pair of expansion / contraction units 102b expand and contract in the directions of the arrows in FIG. 10 by rotating the operating unit 102a. Specifically, when the operating unit 102a is rotated in one direction, the pair of expansion / contraction units 102b expand, and when the operating unit 102a is rotated in the opposite direction, the pair of expansion / contraction units 102b contract.

[0042] Next, we will explain the procedure for repairing a moving handrail 4 using the repair tool 100 according to this embodiment. As an example, we will explain a repair method for when there is a damaged portion 12 on the ear portion 11 of the handrail main body 40, as shown in Figure 3.

[0043] First, steps S1 to S9 are carried out according to the flowchart shown in FIG. Next, the work of step S10 is performed using the repair tool 100. The work of step S10 is performed in the following procedure.

[0044] First, the worker inserts the repair tool 100 into the moving handrail 4, as shown in FIG. Next, as shown in Figure 11, the worker rotates the movement adjustment part 102 of the repair tool 100 to extend the pair of pressing parts 101 together with the corresponding extension parts 102b in the width direction X of the moving handrail 4. At this time, the worker rotates the movement adjustment part 102 with an appropriate force to press the pressing surfaces 101a of the pair of pressing parts 101 against the inside (inner surface) of the corresponding ear parts 11. As a result, the repair canvas 13 adhered to the damaged part 12 of the ear part 11 is compressed by the pressing parts 101.

[0045] Thereafter, the worker presses the repair canvas 13 for a predetermined curing time, and then rotates the movement adjustment part 102 in the opposite direction to the previous rotation, thereby separating the pressing surfaces 101a of the pair of pressing parts 101 from the inside of the corresponding ear parts 11. The worker also rotates the movement adjustment part 102 by a predetermined amount to retract the repair tool 100, and then removes the repair tool 100 from the moving handrail 4.

[0046] In this embodiment, the pair of pressing parts 101 are made of a material (such as ultra-high molecular weight polyethylene) that is non-adhesive to the adhesive used to bond the repair canvas 13. This prevents the pressing parts 101 from sticking to the ears 11, even when the adhesive is cured while the pair of pressing parts 101 is pressing the repair canvas 13, making it possible to easily remove the repair tool 100 from the moving handrail 4.

[0047] As described above, by repairing the moving handrail 4 using the repair tool 100, even if a damaged area 12 occurs inside the ear 11, the repair canvas 13 can be reliably adhered to the damaged area 12. This makes it easy to repair the damaged area 12 that occurs in the ear 11. Note that if the size (length) of the damaged area 12 in the longitudinal direction of the moving handrail 4 is greater than the longitudinal dimension of the holding portion 201 of the repair tool 100, multiple repair tools 100 can be used.

[0048] Incidentally, when repairing damaged section 12 (see Figure 3) on the edge 11 of the moving handrail 4 using the repair tool 100 described above, depending on the state and position of the repair canvas 13, when the movement adjustment part 102 is rotated to stretch the pair of holding parts 101, the holding parts 101 may drag the repair canvas 13, causing the repair canvas 13 to become misaligned. In such cases, it is preferable to use the repair tool described below.

[0049] FIG. 12 is a perspective view showing another configuration example of the repair tool for a moving handrail according to this embodiment. 12, a repair tool 200 for a moving handrail comprises a pair of holding parts 201, a movement adjustment part 202 that connects the pair of holding parts 201, and a plurality (four in this example) of elastic bodies 203. The configuration of the pair of holding parts 201 is the same as the configuration of the pair of holding parts 101 described above, and the configuration of the movement adjustment part 202 is the same as the configuration of the movement adjustment part 102 described above.

[0050] Each elastic body 203 is made of a leaf spring. Leaf springs are preferable because they have a simple structure, are easy to elastically deform, and have low frictional resistance with the existing canvas 10. However, the elastic body 203 is not limited to a leaf spring. Each elastic body 203 is attached to one side 201b of the pressing part 201 by screws. Each elastic body 203 has an elastic force Sp in the thickness direction Z of the pressing part 201, as shown in FIG. 13.

[0051] When repairing a moving handrail 4 using the repair tool 200 configured as described above, the worker inserts the repair tool 200 into the moving handrail 4 with the pair of retaining portions 201 contracted. Next, the worker presses one surface 201b of the pair of retaining portions 201 against the inside of the moving handrail 4, thereby compressing each elastic body 203.

[0052] Next, the worker rotates the movement adjustment part 202 while each elastic body 203 is compressed, thereby stretching the pair of pressing parts 201 in the width direction X of the moving handrail 4. At this time, the pressing surfaces 201a of the pair of pressing parts 201 are maintained in a state spaced apart from the repair canvas 13.

[0053] Thereafter, the worker extends the pair of pressing portions 201 until the pressing surfaces 201a of the pair of pressing portions 201 come into contact with the inside of the ear portion 11. Next, the worker releases the pressure of the pair of pressing portions 201, thereby releasing the compression of each elastic body 203. As a result, each elastic body 203 presses the pair of pressing portions 201 toward one side in the thickness direction Z of the moving handrail 4 (downward in FIG. 14), as shown in FIG. 14. As a result, the repair canvas 13 is compressed by the pressing portions 201.

[0054] By repairing the moving handrail 4 using the repair tool 200 in this manner, if a damaged area 12 occurs inside the ear portion 11, the repair canvas 13 can be pressed against the damaged area 12 without shifting the position of the repair canvas 13.

[0055] The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to facilitate understanding of the present invention, but the present invention is not necessarily limited to those including all of the configurations described in the above-described embodiments. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment. It is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to delete part of the configuration of each embodiment, add other configurations, or replace it with other configurations. [Explanation of symbols]
