  With the above configuration, the cleaning device for the moving handrail of the passenger conveyor is installed on the floor below the reversing part of the moving handrail composed of endless belts on both sides of the passenger conveyor, and the driving roller is below the reversing part of the moving handrail. The power transmission mechanism is driven to rotate by being pressed against the moving handrail, the power transmission mechanism transmits the rotation of the driving roller, and the cleaning roller is transmitted power through the power transmission mechanism and rotates around an axis parallel to the width direction of the moving handrail. Then, the outer peripheral surface to which the cleaning agent is attached is brought into sliding contact with the outer peripheral surface of the moving handrail, and the outer peripheral surface of the moving handrail is cleaned while being wiped, and the cleaning agent supplying means supplies the cleaning agent to the outer peripheral surface of the cleaning roller. .

  Here, since the sliding contact occurs between the outer peripheral surface of the moving handrail and the outer peripheral surface of the cleaning roller, the cleaning ability of the moving handrail is improved.

Below, embodiment of the cleaning apparatus of the handrail of the passenger conveyor which concerns on this invention is described.
FIG. 1 shows a side view of a first embodiment of the present invention, in which a cleaning device 1 is placed on a floor 7 below a reversing part 5 of a moving handrail 3 on both sides of a passenger conveyor and cleans the moving moving handrail 3. Is in a state of performing.

In FIG. 1, a column 11 extends vertically upward from a plate-like device base 9 placed on a horizontal floor 7.
In addition, one end of the support lever 13 is fitted to the support column 11 so as to be freely rotatable within a horizontal plane. Further, the split collars 15 and 16 are fitted and fastened to the upper and lower positions of the support lever 13 of the support 11, whereby the support lever 13 is supported by the support 11.

The split collars 15 and 16 are provided with a screw (not shown) capable of adjusting the fastening force, and the fastening position to the support column 11 can be adjusted up and down by releasing the fastening, whereby the support lever can be adjusted. It is possible to adjust the mounting height of the 13 columns 11.
A lever portion 21 is attached to the other end portion of the support lever 13 via a hinge 19 provided in parallel with the width direction of the moving handrail 3 so as to be rotatable in a vertical plane. A housing 23 whose upper side is opened upward is fixed and supported integrally.

  Further, both end portions of the torsion coil spring 25 as the second elastic body fitted and attached to the hinge 19 are engaged with the support lever 13 and the lever portion 21, respectively, and the elastic force of the torsion coil spring 25 is used. A clockwise moment M shown in the figure is applied to the housing 23 around the hinge 19 to urge the housing 23 in the moving handrail direction (upward). Thereby, the outer peripheral surface of the cleaning roller 27 described later provided in the housing 23 is pressed and brought into contact with the outer peripheral surface of the lower portion of the reversing portion 5 of the moving handrail 3.

Next, the configuration in the housing 23 will be described in more detail.
First, a drive roller 29 and a worm 31 below the drive roller 29 are fixed coaxially to a shaft 33 extending in the vertical direction, and both ends of the shaft 33 are attached to bearings 35 attached to the housing 23. It is pivotally supported. The driving roller 29 is rotationally driven by contact friction with the lower side portion of the reversing portion 5 of the moving handrail 3, and the worm 31 rotates integrally with the driving roller 29.

  Further, as shown in FIG. 2, a worm wheel 37 and a spur gear 39 having a smaller diameter than the worm wheel 37 are fixed coaxially to a shaft 41 extending in the width direction of the movable handrail 3, and both end portions of the shaft 41 are The bearings 43 attached to the housing 23 are pivotally supported. The worm wheel 37 meshes with the worm 31 and is rotated by being greatly decelerated, and the spur gear 39 is rotated integrally with the worm wheel 37 by further reducing the peripheral speed.

Further, a spur gear 45 is coaxially fixed to a shaft 47 extending in the width direction of the moving handrail 3, and both end portions of the shaft 47 are pivotally supported by bearings 49 attached to the housing 23. The gear 39 is engaged.
Further, a spur gear 51 having a diameter larger than that of the spur gear 39 and the cleaning roller 27 are fixed coaxially to a shaft 53 extending in the width direction of the movable handrail 3, and both end portions of the shaft 53 are attached to the housing 23. Further, each bearing 55 is pivotally supported. The spur gear 51 meshes with the spur gear 45 and is driven to rotate, and the cleaning roller 27 rotates integrally with the spur gear 51.

The cleaning roller 27 is formed such that both end portions in the axial direction are curved along the shape of the moving handrail 3, and is configured to guide the moving handrail 3, and a core portion 27a formed of a resin agent or the like, And a wiping cloth 27b covering the outer peripheral surface of the core portion 27a.
With the power transmission mechanism including the worm 31, the worm wheel 37, and the spur gears 39, 45, 51, the cleaning roller 27 has a lower peripheral speed than the driving roller 29, and the moving handrail 3 By rotating while being in sliding contact with the outer peripheral surface, the outer peripheral surface of the moving handrail 3 is wiped by the wiping cloth 27b.

On the other hand, as shown in FIG. 3, the cleaning liquid supply roller 57 is fixed coaxially to a shaft 59 extending in the width direction of the movable handrail 3 below the cleaning roller 27, and both ends of the shaft 59 are connected to the movable handrail 3. Are supported by bearings 61a provided on a pair of bearing plates 61 opposed to each other in the width direction.
Each bearing plate 61 is attached to the bottom of the housing 23 via a spring 63 as a first elastic body that is vertically expandable and contractable, and is integrally formed with the shaft 59 by a guide member 64 erected on the bottom of the housing 23. It is guided so as to be movable in the vertical direction.

With this configuration, the bearing plate 61 is urged upward by the elastic force of each spring 63, and the cleaning liquid supply roller 57 supported by the bearing 61 a is in pressure contact with the outer peripheral surface of the cleaning roller 27 from below.
Here, at least the outer peripheral portion of the cleaning liquid supply roller 57 is formed of a member having liquid absorbency such as sponge rubber, while the bottom of the housing 23 is formed in a cleaning liquid container 23a for storing the cleaning liquid 65 as a cleaning agent. The lower part of the cleaning liquid supply roller 57 is immersed in the cleaning liquid 65 in the cleaning liquid container 23a.

  With such wet cleaning agent supply means, the cleaning liquid supply roller 57 is subordinate to the rotation of the cleaning roller 27 while the outer peripheral surface of the cleaning liquid supply roller 57 impregnated with the cleaning liquid 65 is pressed against the outer peripheral surface of the cleaning roller 27. The cleaning liquid penetrates and is supplied to the outer peripheral surface (wiping cloth 27b) of the cleaning roller 27, and the outer peripheral surface of the moving handrail 3 is wiped by the wiping cloth 27b of the cleaning roller 27 impregnated with the cleaning liquid.

  Although the cleaning liquid is squeezed by the elastic force of the spring 63 at the contact portion of the cleaning liquid supply roller 57 with the cleaning roller 27, the supply amount of the cleaning liquid to the wiping cloth 27b may be adjusted by adjusting the elastic force. That is, if the supply amount is too small, the cleaning ability is deteriorated. On the other hand, if the supply amount is excessive, the cleaning liquid adhering to the moving handrail 3 may adhere to the hand of a passing passenger without being sufficiently dried. Therefore, it is preferable to set the supply amount within a range where such a concern does not occur.

Next, the use of the cleaning device 1 configured as described above will be described.
First, the device base 9 of the cleaning device 1 is placed on the floor 7 below the reversing part 5 of the moving handrail 3. Note that a double-sided tape or the like may be interposed between the device base 9 and the floor 7 so as to be securely fixed.
Next, the support lever 13 is fixed to the support 11 by fastening the split collars 15 and 16 to the support 11, and the outer peripheral surface of the cleaning roller 27 is pressed against the outer peripheral surface of the lower portion of the reversing portion 5 of the moving handrail 3 from below. At the same time, the driving roller 29 is brought into press contact with the side surface of the moving handrail 3.

As a result, the driving roller 29 is rotationally driven as the moving handrail 3 moves, and this driving force is transmitted to the cleaning roller 27 via the power transmission mechanism, so that the cleaning roller 27 is in sliding contact with the outer peripheral surface of the moving handrail 3. Accordingly, the cleaning liquid supply roller 57 impregnated with the cleaning liquid 65 rotates while applying the cleaning liquid 65 to the outer peripheral surface of the cleaning roller 27.
In this way, the cleaning roller 27 wipes the outer peripheral surface of the moving handrail 3 while the cleaning liquid 65 is applied to the outer peripheral surface. Here, since sliding contact is accompanied between the outer peripheral surface of the movable handrail 3 and the outer peripheral surface of the cleaning roller 27, the cleaning ability of the movable handrail 3 is improved.

  Here, as the cleaning roller 27 rotates, the contact surface (cleaning surface) with the moving handrail 3 is moved and replaced, and the lower portion is pressed by the cleaning liquid supply roller 57 and becomes contaminated in the wiping cloth 27b. By draining and supplying a new cleaning liquid impregnated in the cleaning liquid supply roller 57 while discharging the cleaning liquid, the cleaning liquid can be cleaned extremely efficiently, and the wiping cloth 27b can be prevented from collecting dirt in a short time. It is possible to improve the replacement life of the wiping cloth 27b.

  After cleaning the movable handrail 3, the housing 23 is pushed down while being rotated about the hinge 19 against the elastic force of the torsion coil spring 25 while the cleaning device 1 is placed at the cleaning position. 11 is rotated in the horizontal direction around the axis, and retracted from the lower side of the reversing portion 5 of the moving handrail 3 to the outside of the passenger conveyor. Moreover, it can return to a cleaning state easily from an evacuation state by operation | movement contrary to the said evacuation. By the above retraction and return, the trouble of removing and remounting the cleaning device 1 is reduced.

  Further, when the cleaning liquid 65 is replaced, the housing 23 is tilted, and the dirty cleaning liquid 65 is discharged from the open portion on the top of the housing 23. Here, when it is not desired to move the device base 9 from the cleaning position, the split collar 15 is removed from the upper end of the support 11 in the retracted state, and the housing 23 is removed from the support 11 together with the support lever 13. The cleaning liquid 65 is preferably discharged.

Next, a second embodiment of the present invention will be described.
As shown in FIG. 4, the present embodiment is different from the first embodiment in that the cleaning agent supply means is a dry type in which a solid coating agent (solid wax 67) is applied to the outer peripheral surface of the cleaning roller 27. To do.
In FIG. 4, a support plate 71 is bridged between a pair of elevating plates 69 provided in place of the pair of bearing plates 61.

The solid wax 67 is fixed on the support plate 71, and the upper surface of the solid wax 67 is pressed and contacted with the outer peripheral surface of the cleaning roller 27 from below by the elastic force of the spring 63, whereby the outer periphery of the rotating cleaning roller 27 is rotated. A solid wax 67 is applied to the surface.
Here, walls 71 a are provided upright at both ends in the moving direction of the moving handrail 3 on the upper surface of the support plate 71. Even if the solid wax 67 receives a contact frictional force with the cleaning roller 27, It is configured not to fall.

As the solid wax 67 is worn away, the spring 63 extends, and the heights of the lift plate 69 and the support plate 71 rise.
The dry cleaning agent supply means may be used for the purpose of giving gloss to the outer peripheral surface of the moving handrail 3 after sufficiently removing the dirt of the moving handrail 3 by the wet cleaning agent supply means of the first embodiment.

Therefore, the housing 23 using the wet cleaning agent supply means and the housing 23 using the dry cleaning agent supply means have a structure in which the support 11 is attached to the support 11 and attached to the support 11 in a freely detachable manner. Is good.
The present invention is not limited to the above description, and the spur gear 45 is omitted. Instead of the spur gears 39 and 51, pulleys 73 and 75 (the pulley 75 has a larger diameter) are used as shafts 41 and 53, respectively, as shown in FIG. The endless timing belt 77 may be engaged with the pulleys 73 and 75 so as to transmit power. Thereby, cost can be reduced.

Side view of the first embodiment of the present invention Plan view of FIG. Front view of FIG. Front view of the second embodiment of the present invention FIG. 1 is a diagram in which the power transmission mechanism of FIG. 1 is changed to a configuration using a pulley and a timing belt.
