Description

[Technical field]

[0001] The present invention relates to a cleaning device for cleaning the inner peripheral surface of a moving handrail for a passenger conveyor. [Background technology]

[0002] Escalators, which serve as passenger conveyors, have stepped steps that move up and down automatically, balustrades on both sides of the steps, and moving handrails that are installed on the top of the balustrades and move in sync with the steps. The inner circumferential surface of the moving handrail is subjected to frictional force from the rollers that drive the moving handrail. Therefore, dust from the rollers, guide rails, and the periphery of the escalator accumulates on the inner circumferential surface of the moving handrail.

[0003] When dust accumulates on the inner circumferential surface of the moving handrail, the frictional force between the moving handrail and the roller decreases, causing problems in the operation of the moving handrail. Therefore, the inner circumferential surface of the moving handrail is periodically cleaned by an operator. For example, Patent Document 1 discloses a cleaning device for cleaning the inner circumferential surface of the moving handrail. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-261713 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the cleaning device of Patent Document 1 requires an operator to remove the moving handrail. When cleaning the entire inner circumferential surface of the moving handrail on one side of an escalator, the series of operations of removing the moving handrail, cleaning the inner circumferential surface of the moving handrail, and attaching the moving handrail must be performed about three times, which increases the work time. In addition, the work of removing or attaching the moving handrail of an escalator requires a worker who removes or attaches the moving handrail, and several assistant workers who hold the moving handrail during the removal or attachment.

[0006] Therefore, an object of the present invention is to provide a cleaning device for the inner surface of a moving handrail for a passenger conveyor, which allows a single worker to clean the inner surface of the moving handrail in a short time without removing the moving handrail of the passenger conveyor. [Means for solving the problem]

[0012] An example of an embodiment of the present invention will be described in detail below. In the following description, specific shapes, materials, directions, values, etc. are merely examples for the purpose of easily understanding the present invention, and can be appropriately changed according to the application, purpose, specifications, etc.

[0013] As shown in Fig. 4, cleaning device 10 cleans inner circumferential surface 93A of moving handrail 93 of escalator 90 serving as a passenger conveyor. As will be described in detail later, cleaning device 10 allows a single worker to clean inner circumferential surface 93A of moving handrail 93 in a short time without removing moving handrail 93 of escalator 90.

[0014] [escalator] The escalator 90 will be described with reference to FIG.

[0015] As shown in Fig. 1, an escalator 90 according to an embodiment includes a plurality of steps 91 that ascend or descend along an incline, balustrades 92 provided on both sides of the steps 91, and a moving handrail 93 that is provided on the upper part of the balustrade 92 and moves in synchronization with the steps 91. A guide rail is provided on the outer periphery of the balustrade 92 to guide the circulating movement of the moving handrail 93. The guide rails include an outward guide rail 94 and a return guide rail 96, the details of which will be described later, and form a circulating path for guiding the circulating movement of the moving handrail 93.

[0016] As shown in Fig. 2, the outbound guide rail 94 is supported by a guard rail 95. The guard rail 95 prevents passengers' hands from getting caught in the moving handrail 93. The guard rail 95 is supported by a balustrade 92. As shown in Fig. 3, a core wire insertion portion 96A into which a core wire 97 is inserted is formed at the upper portion of the return guide rail 96. The core wire 97 inserted into the core wire insertion portion 96A is fixed to a clamp 98 by a bolt 99. The clamp 98 is fixed to a truss or the like.

[0017] 2 and 3, the moving handrail 93 is made of rubber and is endless, and has a generally C-shaped cross section as viewed in the direction of movement (cross section in the width direction). An inner circumferential surface 93A of the moving handrail 93 receives the frictional force of the rollers that drive the moving handrail 93. For this reason, wear powder from the rollers, wear powder from the outbound guide rail 94 and the return guide rail 96, and dust around the escalator (hereinafter, these will be collectively referred to as dust) accumulates on the inner circumferential surface 93A of the moving handrail 93.

[0018] When dust accumulates on the inner circumferential surface 93A of the moving handrail 93, the frictional force between the inner circumferential surface 93A of the moving handrail 93 and the roller decreases, causing slippage between the moving handrail 93 and the roller. As a result, the movement of the moving handrail 93 and the tread plate becomes misaligned, making the ride uncomfortable for passengers. In order to avoid such a situation, it is necessary to periodically clean the inner circumferential surface 93A of the moving handrail 93. The following describes a cleaning device 10 for cleaning the inner circumferential surface 93A of the moving handrail 93 in a short time by one worker without removing the moving handrail 93 of the escalator 90.

[0019] [Cleaning device] A cleaning device 10 as an example of an embodiment will be described with reference to FIG.

[0020] The cleaning device 10 is provided on the outbound path of a moving handrail 93 of an escalator 90 and comprises a moving handrail operation detection unit 20 that detects whether the moving handrail 93 is operating or stopped, a cleaning and dust collecting unit 60 that is provided on the return path of the moving handrail 93 and wipes up dust on the inner surface 93A of the moving handrail 93, and a dust collector 70 that operates or stops in synchronization with the operation or stop of the moving handrail 93 detected by the moving handrail operation detection unit 20 and sucks up the dust wiped up by the cleaning and dust collecting unit 60.

[0021] The cleaning device 10 may be configured to include one moving handrail operation detection unit 20, cleaning and dust collecting units 60 attached to the left and right moving handrails 93, respectively, and one dust collector .

[0022] [Moving handrail operation detection unit] The moving handrail operation detection unit 20 will be described with reference to Figs.

[0023] The movable handrail operation detection unit 20 is fixed to a guardrail 95 that holds a forward guide rail 94 that guides the movable handrail 93, and has a base 30 having a base axis 33, a synchronous rotation unit 40 that is rotatable around the base axis 33 and rotates in the forward direction in synchronization with the operation of the movable handrail 93, a leaf spring 43 that biases the synchronous rotation unit 40 in the reverse direction, a microswitch 50 provided at the tip of the synchronous rotation unit 40, a rotor 55 provided at the tip of a push button 50A of the microswitch 50, and a switch cam 56 provided on the base 30 and having a recess 56A as a cam with which the rotor 55 engages.

[0024] The base 30 is fixed to the guardrail 95 across the moving handrail 93 and the guardrail 95, and rotatably supports the synchronous rotation unit 40 described below. The base 30 has a horizontal base unit 31 arranged above the moving handrail 93, and a pair of vertical base units 32 arranged on the sides of the moving handrail 93 and the guardrail 95, respectively. A base shaft 33 protruding upward is provided on the horizontal base unit 31. A synchronous rotation unit 40 described below is rotatably provided on the base shaft 33. A pair of clamping units 34 protruding inward are provided on the lower part of the vertical base unit 32. The clamping units 34 clamp the guardrail 95.

[0025] In the base 30, the horizontal base portion 31 and the vertical base portion 32 may each have a recess formed therein, and the horizontal base portion 31 and the vertical base portion 32 may be fixed to each other by engaging the recesses with each other. Also, in the base 30, the vertical base portion 32 may be fixed to the guardrail 95 by fixing the clamping portion 34 to the guardrail 95 with fixing screws 35 from below or laterally.

[0026] The synchronous rotation part 40 is rotatable around the base shaft 33 and rotates in the forward direction (counterclockwise direction in FIG. 5) in synchronization with the movement of the moving handrail 93. The synchronous rotation part 40 has a main body 41 and a synchronizing part 42, the details of which will be described later.

[0027] The main body 41 is formed in a flat plate shape and is disposed across the horizontal base portion 31. An opening is formed at one end of the main body 41 in the width direction, through which the base shaft 33 is inserted. A microswitch 50, which will be described later, is provided at the other end of the main body 41 in the width direction (the tip of the synchronous rotation portion 40). A protrusion 41A that protrudes upward is formed at each of the front end and rear end in the movement direction of the main body 41. A leaf spring 43 that is U-shaped in plan view, which will be described later, is engaged between the protrusions 41A.

[0028] The synchronizing parts 42 are provided at the lower part of one end in the width direction of the main body 41 (the tip of the synchronizing rotating part 40), at the front end and the rear end in the moving direction of the main body 41, and abut against the surface of the moving handrail 93. The synchronizing parts 42 are preferably made of rubber. In addition, the horizontal base part 31 is arranged between the synchronizing parts 42. The leaf spring 43 is formed in a U-shape in a plan view, and is engaged between the protrusions 41A of the main body 41 so that the open side faces the other side in the width direction. One end in the width direction of the leaf spring 43 is fixed to the base shaft 33.

[0029] With the above configuration, as the moving handrail 93 operates, the frictional force between the synchronizing portion 42 and the moving handrail 93 causes the synchronizing rotation portion 40 to rotate in the forward direction around the base shaft 33 in synchronization with the moving handrail 93. The rotation of the synchronizing rotation portion 40 is stopped when the synchronizing portion 42 on the rear end side in the moving direction abuts against the horizontal base portion 31. Meanwhile, as the moving handrail 93 stops, the biasing force of the leaf spring 43 causes the synchronizing rotation portion 40 to rotate in the reverse direction around the base shaft 33.

[0030] The microswitch 50 is a change-over switch in which the contact is turned ON by pressing the push button 50A and the contact is turned OFF by releasing the pressing of the push button 50A. The ON or OFF state of the microswitch 50 is synchronized with the operation or stop of the dust collector 70, which will be described later. The microswitch 50 is provided at the tip of the synchronous rotation part 40 so that the push button 50A faces the tip side of the synchronous rotation part 40.

[0031] The rotor 55 is formed in a cylindrical shape and is rotatably supported at the tip of the push button 50A of the microswitch 50. The switch cam 56 is provided on the horizontal base portion 31 of the base 30 on the other side of the width direction of the synchronous rotation portion 40. A recess 56A is formed on one side of the width direction of the switch cam 56 with which the rotor 55 engages when the moving handrail 93 is stopped. The recess 56A is formed as a trapezoidal notch.

[0032] With the above configuration, when the moving handrail 93 is operated, the synchronous rotation part 40 rotates in the forward direction around the base shaft 33 in synchronization with the moving handrail 93, the rotor 55 disengages from the recessed part 56A of the switch cam 56, the push button 50A of the microswitch 50 is pressed, and the microswitch 50 is turned ON. On the other hand, when the moving handrail 93 stops, the synchronous rotation part 40 rotates in the reverse direction around the base shaft 33, the rotor 55 engages with the recessed part 56A of the switch cam 56, the pressure on the push button 50A of the microswitch 50 is released, and the microswitch 50 is turned OFF.

[0033] As a result, the microswitch 50 is turned ON when the moving handrail 93 is operated, and the microswitch 50 is turned OFF when the moving handrail 93 is stopped. In other words, the dust collector 70, which will be described later, is operated or stopped in synchronization with the operation or stop of the moving handrail 93.

[0034] [Cleaning and dust collection section] The cleaning and dust collecting section 60 will be described with reference to FIGS.

[0035] The cleaning and dust collection unit 60 comprises a cleaning unit 61 formed in a cross-sectional shape that follows the inner surface 93A of the moving handrail 93, a nonwoven fabric 64 as a cleaning cloth that is attached to the surface of the cleaning unit 61 and adheres to the inner surface 93A of the moving handrail 93, a dust collection hose 65 having a tip end 65A provided on the rear side of the cleaning unit 61 and connected to the dust collector 70, a pair of L-shaped core wires 66 provided on the front side of the cleaning unit 61 in the movement direction of the moving handrail 93 and on the rear side of the tip end 65A of the dust collection hose 65, respectively, and inserted into a core wire insertion portion 96A of a return way guide rail 96 that guides the moving handrail 93, a connecting fixing device 67 that connects and fixes the tip end 65A of the dust collection hose 65, the cleaning unit 61 and the L-shaped core wire 66, and a short pressing bracket 68 that holds the L-shaped core wire 66.

[0036] The cleaning unit 61 is divided into three in the width direction, and has a generally rectangular central section 62 and two folded sections 63 that have an L-shaped cross section when viewed from the direction of movement. The horizontal section 63A of the folded sections 63 has an arc-shaped cross section when viewed from the direction of movement of the tip so as to fit along the inner circumferential surface 93A of the moving handrail 93. The cleaning unit 61 can be easily attached to the inner circumferential surface 93A of the moving handrail 93, as will be described in detail later.

[0037] As described above, the nonwoven fabric 64 is attached to the surface of the cleaning unit 61 and is in close contact with the inner circumferential surface 93A of the moving handrail 93, and as the moving handrail 93 moves, it wipes up dust on the inner circumferential surface 93A of the moving handrail 93. As the nonwoven fabric 64, a commercially available cleaning cloth (for example, a nylon nonwoven fabric) is suitably used.

[0038] The dust collection hose 65 is a pipe that sends the dust wiped up by the nonwoven fabric 64 to the dust collector 70. The dust collection hose 65 is preferably made of a soft material such as rubber, vinyl, or plastic. The dust collection hose 65 is connected to the dust collector 70. A tip end 65A of the dust collection hose 65 is provided on the rear side of the cleaning unit 61.

[0039] The L-shaped core metal 66 is formed in an L-shape when viewed in the width direction. A horizontal portion 66A of the L-shaped core metal 66 is inserted into a core metal insertion portion 96A of the return path guide rail 96, and a screw hole into which the bolt 69 is screwed is formed, similar to the core metal 97. It is preferable that the length of the L-shaped core metal 66 in the width direction is approximately the same as the length of the cleaning section 61 in the width direction.

[0040] The connecting fixture 67 is a pair of long members connected by connectors such as screws and wing nuts, and connects and fixes the tip end 65A of the dust collection hose 65, the cleaning part 61, and the L-shaped core metal 66. The shape of the connecting fixture 67 is preferably formed so as to fit along the respective side surfaces of the tip end 65A of the dust collection hose 65, the cleaning part 61, and the L-shaped core metal 66. The short pressing metal fitting 68 has approximately the same cross-sectional shape as the pressing metal fitting 98 when viewed from the movement direction, and is short in shape. The short pressing metal fitting 68 is fixed to the L-shaped core metal 66 by bolts 69.

[0041] [Installation of cleaning and dust collection unit] 10 to 12, the attachment of the cleaning and dust collecting unit 60 to the moving handrail 93 will be described.

[0042] 10, the short return path guide rail 96 is removed to provide space for attaching the cleaning and dust collecting unit 60. To remove the short return path guide rail 96, the bolts 99 that secure the core metal 97 and the clamping bracket 98 are loosened, and the core metal 97, the clamping bracket 98, and the bolts 99 are slid in one direction in the movement direction to remove the short return path guide rail 96.

[0043] Next, as shown in Fig. 11, the cleaning unit 61 and the nonwoven fabric 64 are attached to the inner circumferential surface 93A of the moving handrail 93. At this time, first, the nonwoven fabric 64 is brought into close contact with the inner circumferential surface 93A of the moving handrail 93. Next, each folded portion 63 is inserted and brought into close contact with the nonwoven fabric 64. Next, the central portion 62 is inserted between the folded portions 63 and brought into close contact with the nonwoven fabric 64. In other words, the folded portions 63 are inserted one by one into the moving handrail 93 without the central portion 62, and then the central portion 62 is inserted, thereby easily attaching the cleaning unit 61 and the nonwoven fabric 64 to the inner circumferential surface 93A of the moving handrail 93.

[0044] Next, as shown in Fig. 12, the cleaning and dust collecting unit 60 is attached to the moving handrail 93. At this time, first, the cleaning unit 61 and the nonwoven fabric 64 are attached to the inner peripheral surface 93A of the moving handrail 93 as described above. Next, the L-shaped core metal 66 is inserted into the core metal insertion portion 96A of the return path guide rail 96, and the L-shaped core metal 66 is attached to the return path guide rail 96 by the short clamping metal fitting 68 and the bolt 69. Next, the tip portion 65A of the dust collecting hose 65 is disposed between the cleaning unit 61 and the rear L-shaped core metal 66. Next, the tip portion 65A of the dust collecting hose 65, the cleaning unit 61, and the L-shaped core metal 66 are connected and fixed by the connecting fixture 67.

[0045] [Dust collector] The dust collector 70 will be described again with reference to FIG.

[0046] The dust collector 70 sucks up and collects the dust swept up by the cleaning dust collection unit 60. The operation or stop of the dust collector 70 is synchronized with the ON or OFF of the microswitch 50 of the moving handrail operation detection unit 20. The dust collector 70 may be installed at the entrance 90A of the escalator 90. The dust collector 70 may be a commercial vacuum cleaner.

[0047] [Cleaning the inner surface of handrails] The cleaning operation of the inner circumferential surface 93A of the moving handrail 93 of the escalator 90 using the cleaning device 10 will be described.

[0048] First, as described above, the cleaning and dust collection unit 60 is attached to the moving handrail 93 on the return path. Next, the moving handrail operation detection unit 20 is attached to the guardrail 95 on the outbound path. Next, the escalator 90 is operated by manual operation. At this time, dust is wiped and accumulated in front of the cleaning unit 61 by the movement of the moving handrail 93, and the dust collector 70 is operated by the movement of the moving handrail 93 to suck up the accumulated dust. After the escalator 90 has been operated for several revolutions, the escalator 90 is stopped by manual operation, and the dust collector 70 also stops.

[0049] In this way, cleaning device 10 allows a single worker to clean inner circumferential surface 93A of moving handrail 93 of escalator 90 in a short time without removing the moving handrail 93.

[0050] It should be noted that the present invention is not limited to the above-described embodiment and its modified examples, and various modifications and improvements are possible within the scope of the matters described in the claims of this application. [Explanation of symbols]
