In the case of the handrail belt as described above, the cleaning worker can easily access it, but it is located on the outside of the balustrade, for example, the deck board formed on the outside of the balustrade that defines the moving path where the steps of the passenger conveyor move. Is not easy to access. In particular, when the balustrade is formed of a glass board, the deck board is formed at a position close to the balustrade base on the outside of the balustrade, and dust and the like are likely to accumulate. In this case, there are problems that the cleaning tool is difficult to reach the deck board formed at the base outside the balustrade, efficient cleaning cannot be performed, and sufficient cleaning cannot be performed. In addition, when the balustrade is composed of glass panels, the outside of the balustrade is often open, and there is a problem that it is difficult to ensure safety during work. Therefore, if a cleaning device for a passenger conveyor that can safely and efficiently clean the outside of the balustrade can be provided, it is meaningful to reduce the cleaning work.

The passenger conveyor cleaning device of the embodiment includes a fixing member, an arm member, and a cleaning member. The fixing member is placed on the upper part of the balustrade provided on the side of the moving path of the passenger conveyor on which multiple steps connected in an endless manner run, and can be attached to the handrail belt that moves in the same direction in synchronization with the steps. Is. The arm member is connected to the fixing member and extends toward the base of the balustrade on the opposite side of the balustrade with the balustrade in between. The cleaning member is fixed to the arm member and cleans the outer area of the balustrade. The arm member is provided with a disk-shaped drive roller that comes into contact with the wall surface on the opposite side of the balustrade and is pivotally supported so as to rotate along the wall surface as the fixing member moves. Rotate the cleaning member.

Hereinafter, the passenger conveyor cleaning device according to the embodiment will be described in detail with reference to the drawings. It should be noted that the components in this embodiment include those that can be replaced by those skilled in the art and are easily or substantially the same, and the present invention is not limited to the following embodiments.

FIG. 1 is an exemplary and schematic side view showing the structure of an escalator 12 as an example of a passenger conveyor to which the passenger conveyor cleaning device of the embodiment (hereinafter referred to as a cleaning device 10) can be mounted. Further, FIG. 2 is an exemplary and schematic top view showing a part of the escalator 12 equipped with the cleaning device 10.

The escalator 12 constitutes a movement path R for transporting an object such as a user or luggage by operating by rotating (circulating) a plurality of steps 14 connected in an endless manner. In FIG. 1, a truss T is installed between the upper floor side floor UF and the lower floor side floor DF of a building (building). A deck D is installed on the truss T, and the balustrade panel GP constituting the balustrade W is supported. Further, a handrail belt 16 is provided on the balustrade deck at the upper end of the balustrade panel GP.

The underfloor of the boarding / alighting portion (boarding / alighting plate 18) of the escalator 12, that is, the underfloor space 20, accommodates a drive mechanism for orbiting the step 14. The underfloor space 20 communicates from the upper floor side to the lower floor side. The drive mechanism of the escalator 12 mainly includes a motor 24 as a drive source, a speed reducer 26, a drive chain 28, a drive sprocket 30, a driven sprocket 32, and a step chain 34. The motor 24 and the speed reducer 26 constitute a drive device 22. The motor 24 is provided, for example, on the upper floor side. A speed reducer 26 is attached to the output shaft of the motor 24. The speed reducer 26 decelerates the rotation of the motor 24 and amplifies the rotation torque of the motor 24. The reduction sprocket 26a is provided on the output shaft of the reduction gear 26 and has a plurality of teeth. The drive chain 28 is formed in an endless shape and is hung over the deceleration sprocket 26a and the drive sprocket 30. The drive chain 28 rotates the drive sprocket 30 by circulating around the drive sprocket 30 and the deceleration sprocket 26a by the driving force of the motor 24 transmitted via the speed reducer 26. That is, the drive chain 28 transmits the driving force of the motor 24 transmitted via the speed reducer 26 to the drive sprocket 30. The drive sprocket 30 has a plurality of teeth that mesh with the step chain 34, and is rotated by a drive force from the drive device 22.

The escalator 12 operates by driving a step chain 34 spanned between the drive sprocket 30 and the driven sprocket 32 to orbit a plurality of step 14s connected in an endless manner. As a result, the step chain 34 runs a plurality of steps 14.

When the escalator 12 operates in the descending direction (arrow S direction), at the tip portion of the boarding / alighting plate 18 of the upper floor UF, the adjacent steps 14 among the plurality of steps 14 are horizontal to each other in the traveling direction. It is advanced from inside the truss T. Then, in the upper transition curve 36s1, the step between the adjacent steps 14 is enlarged, and the plurality of steps 14 are transitioned in a step shape. In the intermediate tilting portion, the plurality of steps 14 are descended in a staircase pattern. Subsequently, in the lower transition curve 36s2, the step between the adjacent steps 14 is reduced, and the plurality of steps 14 are changed horizontally. At the tip of the boarding / alighting plate 18 of the lower floor DF, the plurality of steps 14 become horizontal again and enter the truss T. The plurality of steps 14 are turned upside down after entering the truss T, and are raised with the tread surface (cleat surface) of the step 14 horizontal on the return side. After that, the plurality of steps 14 are inverted again at the position of the drive sprocket 30, and are advanced from the inside of the truss T at the tip portion of the boarding / alighting plate 18 of the floor UF on the upper floor side. In the escalator 12 that operates in the ascending direction, the operation is the reverse of the above-mentioned operation. In this way, at the tip of the boarding / alighting plate 18 of the upper floor UF and the lower floor DF, the step 14 advances from the truss T with the tread on the upper surface on which the user is placed horizontal. Or enter the truss T.

The escalator 12 includes a pair of balustrades W on both sides of the plurality of steps 14 in the traveling direction. The balustrade W is supported by the deck board 36, the skirt guard panel 56 (see FIG. 4), the inner deck 54 (see FIG. 4), the balustrade panel GP, and the balustrade deck provided at the outer edge of the balustrade panel GP. It is composed of a handrail belt 16 provided on the handrail rail. The skirt guard panel 56 is close to each other on both sides in a direction (width direction) orthogonal to the traveling direction (for example, the descending direction and the ascending direction in which the escalator 12 operates) of the plurality of steps 14, and is on the upper floor. It is provided between the boarding / alighting board 18 of the UF and the boarding / alighting board 18 of the lower floor DF. An inner deck 54 is attached to the upper side of the skirt guard panel 56. On the upper side of the inner deck 54, for example, a balustrade panel GP made of a transparent or translucent member such as a glass plate or a metal plate such as stainless steel is attached. The handrail belt 16 is movably fitted to the handrail rail attached to the outer periphery of the balustrade panel GP. The handrail belt 16 orbits by a moving handrail drive chain that is orbitally driven in synchronization with the step chain 34, advances from, for example, the inlet Da on the lower floor side, and enters the inlet Da on the upper floor side. The step 14 and the handrail belt 16 rotate in synchronization with each other in the same direction.

Such operation of the escalator 12 is realized, for example, by controlling the speed reducer 26 and the motor 24 by the control panel M installed in the underfloor space 20 in the truss T. The control panel M is physically realized by a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The function executed in the control panel M is to load the application program held in the ROM into the RAM and execute it in the CPU to operate various devices in the escalator 12 under the control of the CPU, and also to operate the RAM and the RAM. It is realized by reading and writing data in ROM. In the case of FIG. 1, the operation operation device Ma is arranged on the skirt guard panel 56 on the lower floor side floor DF side. In the operation operation device Ma, it is possible to switch the operation direction, operation speed, etc. of the escalator 12 according to the usage situation, the usage time zone, and the like of the user.

FIG. 3 is an exemplary and schematic side view showing a part of the escalator 12 showing a state in which the cleaning device 10 is attached. Further, FIG. 4 is an exemplary and schematic side view showing a detailed configuration when the cleaning device 10 is viewed from the entrance / exit side, and FIG. 5 shows a fixing member (main body fixing member 38) of the cleaning device 10. It is an exemplary and schematic top view which shows the periphery in detail.

The cleaning device 10 of the present embodiment is a device that mainly cleans the deck board 36 existing at the base of the balustrade W outside the balustrade W of the escalator 12. The cleaning device 10 itself does not have a drive power source for cleaning, and uses the drive of the handrail belt 16 of the escalator 12 to perform cleaning work on the deck board 36 and the like.

The cleaning device 10 is mainly composed of a fixing member (main body fixing member 38), an arm member (mop arm 42), and a cleaning member (mop main body 44).

The main body fixing member 38 as a fixing member is arranged on the upper part of the balustrade W provided on the side of the moving path R of the escalator 12 on which a plurality of step 14s connected in an endless manner travel, and is synchronized with the step 14. It is a member that can be attached to the handrail belt 16 that moves in the same direction. Further, the mop arm 42 as an arm member is a member that is connected to the main body fixing member 38 via a connecting arm 40 and extends toward the base of the balustrade W on the opposite side of the step 14 with the balustrade W interposed therebetween. Further, the mop body 44 as a cleaning member is fixed to the mop arm 42 and cleans the outer region of the balustrade W.

Subsequently, the details of each constituent member constituting the cleaning device 10 will be described.

As shown in FIG. 5, the main body fixing member 38 is a member having a substantially rectangular shape in a top view, and as shown in FIG. 4, the main body fixing member 38 is engaged at both ends of the handrail belt 16 in the width direction (arrow B direction). , A member that covers from the surface side. As shown in FIG. 4, the end portion of the main body fixing member 38 on one side (inside, step 14 side) in the width direction (arrow B direction) corresponds to the shape of the handrail belt 16 having a substantially C-shaped cross section. A first grip portion 38a having a curved cross-sectional shape is formed. Due to the curved shape of the first grip portion 38a, the main body fixing member 38 wraps around the lower part of the handrail belt 16 and easily engages with (easily catches) the handrail belt 16. On the other hand, the end portion of the main body fixing member 38 on the other side (outside, deck board 36 side) in the width direction forms a second grip portion 38b having a cross-sectional shape extending linearly downward.

Therefore, when the main body fixing member 38 is attached to the handrail belt 16 in the movement stopped state, first, the first grip portion 38a is hooked inward in the width direction of the handrail belt 16 in an oblique posture tilted inward (step 14 side). Then, by tilting the posture of the main body fixing member 38 so as to be parallel to the upper surface of the handrail belt 16, the second grip portion 38b is brought into sliding contact with the outer surface of the handrail belt 16 in the width direction, as shown in FIG. Can be attached. A non-slip member 46 made of, for example, a flexible rubber member is fixed to the side (inner surface side) of the main body fixing member 38 that comes into contact with the handrail belt 16. Therefore, the main body fixing member 38 is firmly fixed to the handrail belt 16 by the elastic deformation of the non-slip member 46 and its grip force. Further, since the second grip portion 38b side has a linear shape, it can be easily removed by raising the posture of the main body fixing member 38 diagonally upward. As shown in FIG. 4, the main body fixing member 38 has a heavy object such as a mop arm 42 or a mop main body 44 via a connecting arm 40 on the side of the second grip portion 38b opposite to the first grip portion 38a. Since they are connected, the posture change diagonally upward is unlikely to occur unless the user of the cleaning device 10 intentionally performs the posture change. Also in this respect, the main body fixing member 38 has a structure that does not easily come off from the handrail belt 16 during cleaning by the cleaning device 10 described later. The main body fixing member 38 may be provided with a lock mechanism that makes it possible to adjust the holding width of the handrail belt 16 in the width direction by using a screw or the like.

The connection arm 40 is, for example, a substantially L-shaped member to which the first portion 40a and the second portion 40b are connected, and is an intermediate member for connecting the main body fixing member 38 and the mop arm 42. One end side of the first portion 40a is connected to a bracket 38c fixed to the outer surface side of the second grip portion 38b of the main body fixing member 38 via a bearing 48 whose rotation axis is directed in the direction of arrow B in FIG. There is. That is, the connecting arm 40 can swing in the moving direction of the step 14. The effect of the bearing 48 will be described later.

Further, one end side of the second portion 40b as an auxiliary arm member extending in the arrow B direction is connected to the other end side of the first portion 40a. A bearing 50 having a rotation axis oriented in the direction of arrow C substantially parallel to the balustrade panel GP is provided at the connection base of the second portion 40b to support the mop arm 42. That is, the mop arm 42 can rotate about the axis in the extending direction of the mop arm 42, for example, in the direction of the arrow RB. A weight 58 is connected to the other end side of the second portion 40b. The effect of the weight 58 will be described later.

The mop body 44 is fixed to the other end side of the mop arm 42 whose one end side is supported by the bearing 50. The mop arm 42 is, for example, a columnar rod-shaped member, and a disk-shaped drive roller 52 is fixed (shaft-supported) to an intermediate portion thereof. In the case of FIG. 4, the drive roller 52 is fixed at a position closer to the bearing 50. The drive roller 52 has a radius such that the outer peripheral surface abuts on the outer peripheral side of the balustrade panel GP in a posture in which the main body fixing member 38 is attached to the handrail belt 16. That is, when the handrail belt 16 moves in the moving direction (arrow S direction) together with the step 14, the main body fixing member 38 fixed to the handrail belt 16 and the mop fixed to the main body fixing member 38 via the connecting arm 40. The arm 42 also moves in the same direction. At this time, the drive roller 52 comes into contact with the balustrade panel GP and rolls on the balustrade panel GP, for example, in the direction of arrow BR. That is, the mop arm 42 rotates in the direction of the arrow BR. As a result, the mop body 44 fixed to the tip is rotationally driven in the same direction.

The mop body 44 can be, for example, a structure in which piles with long hairs are bundled or a pile fabric with short hairs supported by a frame, and when the body fixing member 38 is attached to the handrail belt 16. The mop body 44 is configured to come into contact with the deck board 36. The pile of the mop body 44 can be impregnated with an adsorbent, for example, so that dust can be efficiently entangled. Further, as described above, when the main body fixing member 38 fixed to the handrail belt 16 moves with the movement of the handrail belt 16, the mop arm 42 rotates by the rotation of the drive roller 52. As a result, the mop body 44 moves while rotating on the deck board 36, and dust can be entangled more efficiently.

For example, a rubber sheet or the like is fixed to the outer peripheral surface of the disk-shaped drive roller 52 to increase the contact resistance with the balustrade panel GP and suppress rotation failure of the mop arm 42 (mop body 44) due to slippage. There is. Further, as described above, the weight 58 is attached to the other end side of the second portion 40b of the connection arm 40. The weight 58 generates an urging force that urges the drive roller 52 to the balustrade panel GP by the principle of the lever. As a result, the slip of the drive roller 52 with respect to the balustrade panel GP is further suppressed (to improve the rotational driving force), and the mop arm 42 (mop main body 44) is rotated more stably.

When using the cleaning device 10 configured as described above, for example, the main body fixing member 38 is attached to the handrail belt 16 in a state where the handrail belt 16 (step 14) is stopped on the upper floor UF. At the same time, the mop body 44 is brought into contact with the deck board 36. Then, the escalator 12 is operated toward, for example, the lower floor DF. As a result, the handrail belt 16 starts to move around as the step 14 moves, and the cleaning device 10 moves from the upper floor to the lower floor with the mop body 44 in contact with the deck board 36. At that time, the mop arm 42 (mop main body 44) is rotated by the rotation of the drive roller 52, and dust and the like existing (accumulated) on the deck board 36 are entangled and cleaned. When the cleaning device 10 arrives at the end of the lower floor DF of the deck board 36, the operation of the cleaning device 10 is stopped, and the main body fixing member 38 (cleaning device 10) is removed from the handrail belt 16. When the main body fixing member 38 is attached to the handrail belt 16 on the lower floor DF, if the escalator 12 is operated so that the step 14 moves from the lower floor to the upper floor, the same cleaning is performed by the cleaning device 10. It can be performed. Cleaning by the cleaning device 10 can be completed by one-way traveling from the upper floor to the lower floor or from the lower floor to the upper floor, but it may be reciprocated between the upper floor and the lower floor.

As shown in FIG. 1, the deck board 36 has an upper transition curve 36s1 connecting the horizontal portion 36a and the inclined portion 36b on the floor UF side on the upper floor side. Similarly, on the lower floor DF side, there is a lower transition curve 36s2 connecting the inclined portion 36b and the horizontal portion 36c. In the cleaning device 10, as described above, the bracket 38c on the main body fixing member 38 side and the connecting arm 40 (first portion 40a) are connected via the bearing 48, and the connecting arm 40 swings in the moving direction of the step 14. It is possible. Therefore, when the cleaning device 10 approaches the upper transition curve 36s1 or the lower transition curve 36s2, the connection arm 40, the mop arm 42, and the mop body 44 swing according to the upper transition curve 36s1 or the lower transition curve 36s2. The contact state between the mop body 44 and the deck board 36 is maintained. As a result, almost uniform cleaning can be performed by the mop body 44 in the entire area of the deck board 36. Even in the case of the escalator 12 having a structure in which the distance between the handrail belt 16 and the deck board 36 changes in the middle, the mop arm 42 (mop body 44) swings as described above, and the mop arm 42 is slanted. By setting this, the difference in the distance between the handrail belt 16 and the deck board 36 can be absorbed, and cleaning can be continued.

As described above, the main body fixing member 38 includes the non-slip member 46 and has a structure that can be firmly fixed to the handrail belt 16, but may also have a fall prevention structure as shown in FIGS. 3 and 5. .. Specifically, the auxiliary fixing member 60 is attached to the handrail belt 16 at the rear position of the main body fixing member 38 with respect to the moving direction of the main body fixing member 38, similarly to the main body fixing member 38. The main body fixing member 38 and the auxiliary fixing member 60 are connected by a fall prevention wire 62. The structure of the auxiliary fixing member 60 can be the same as that of the main body fixing member 38. The fall prevention wire 62, the main body fixing member 38, and the auxiliary fixing member 60 are fixed by fixing members 62a, 62b, etc. such as screws. As described above, the cleaning device 10 is provided with a double fixing structure to reliably prevent inconveniences such as falling off from the handrail belt 16 during cleaning work.

As described above, the cleaning device 10 can be easily attached to the handrail belt 16 and can perform the cleaning work of the deck board 36. In particular, the balustrade panel GP is composed of a glass panel, and the outside of the balustrade panel GP can be clearly seen by the balustrade lighting 64, and even if dirt is easily noticeable, cleaning work can be easily performed and the deck board 36 is kept clean. It will be easier. Further, even if the deck board 36 is difficult to clean outside the balustrade W, the cleaning work can be performed safely and quickly, so that the work efficiency can be improved and the work load of the worker can be reduced. can.

FIG. 6 is an exemplary and schematic side view showing the cleaning device 10A (passenger conveyor cleaning device) having another configuration in detail. The cleaning device 10A has substantially the same configuration except that the mop body 66 is different from the mop body 44 of the cleaning device 10 shown in FIG. Therefore, in the cleaning device 10A, the same components as those of the cleaning device 10 are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 6, the mop body 66 of the cleaning device 10A has a bottom mop portion 66a that can contact the deck board 36 and a side mop portion 66b that can contact the wall surface on the outside (deck board 36 side) of the balustrade panel GP. It is composed of a substantially cylindrical shape. Similar to the mop body 44, the bottom mop portion 66a and the side mop portion 66b can have a structure in which piles with long hairs are bundled, a structure in which pile fabrics with short hairs are supported by a frame, and the like.

Also in the case of the cleaning device 10A, the mop arm 42 to which the mop body 66 is fixed is rotatably supported by the bearing 50 of the connection arm 40 (second portion 40b). Further, the mop arm 42 comes into contact with the outer wall surface of the balustrade panel GP, and when the cleaning device 10A moves in the moving direction of the step 14 together with the handrail belt 16, the mop arm 42 is rotationally driven. As a result, the cleaning device 10A can simultaneously clean the outer wall surface of the deck board 36 and the balustrade panel GP. The portion of the upper wall surface on the outside of the balustrade panel GP where the side mop portion 66b does not come into contact can be cleaned, for example, by extending the hand over the handrail belt 16 to the outside of the balustrade panel GP. It can be dealt with by cleaning manually.

If the mop body 66 of the cleaning device 10A is configured to include a side mop portion 66b around a hollow cylindrical tube, the mop arm 42 of the cleaning device 10 is provided after the mop body 44 of the cleaning device 10 is removed. By exchanging the mop body 44 and the mop body 66 as attachments, the other parts can be used in common.

As described above, according to the cleaning device 10A, it is possible to more efficiently clean the outside of the balustrade panel GP, and it is possible to perform a wider range of cleaning work in a short time while reducing the burden on the operator. Can be done. The cleaning device 10A has a configuration having only a side mop portion 66b that can contact the outer wall surface of the balustrade panel GP, or a wall surface outside the balustrade panel GP that has a bottom mop portion 66a but does not come into contact with the deck board 36. It may be a dedicated cleaning device.

In the case of the cleaning device 10 and the cleaning device 10A described above, an example is shown in which the mop arm 42 (mop main body 44, mop main body 66) provided with the drive roller 52 rotates for cleaning. As another embodiment, a simple type cleaning device 10 (cleaning device 10A) may be configured. For example, the rotation function may be omitted from the cleaning device 10 (cleaning device 10A). In this case, the drive roller 52, the bearing 50, and the weight 58 can be omitted, and the mop body 44 (mop body 66) cleans the outer wall surface of the deck board 36 and the balustrade panel GP by sliding. For example, in the case of light dirt such as dust, a sufficient cleaning effect can be obtained even with this simple type. Further, in the case of cleaning by the simple type, the dust is only pushed away mainly in the moving direction along the deck board 36. In this case, when the side of the deck board 36 opposite to the balustrade panel GP is open, there is also an effect that it is difficult to drop dust from the open side of the deck board 36 to the lower floor.

Further, the simple type may be configured as a dedicated device, or the drive roller 52 and the weight 58 can be attached to and detached from the so-called rotary drive type cleaning device 10 (cleaning device 10A) described with reference to FIGS. 4 and 6. At the same time, as a configuration (with a lock mechanism) capable of fixing the support of the mop arm 42 by the bearing 50, it may be possible to switch between a rotary drive type and a non-rotary drive type similar to the simple type depending on the cleaning situation.

Further, in the above-described embodiment, the mop arm 42 may have a telescopic structure. For example, depending on the model of the escalator 12, the position (height) of the deck board 36 may differ in the direction of the arrow C in FIGS. 4 and 6. In such a case, by adjusting the expansion and contraction of the mop arm 42, the mop body 44 (mop body 66) can be appropriately brought into contact with the deck board 36, and cleaning can be reliably performed. When the mop arm 42 expands and contracts, the side mop portion 66b of the mop body 66 also needs to expand and contract in the direction of arrow C. In this case, for example, the side mop portion 66b may be divided into a plurality of parts and the number of stacks may be adjusted to match the expansion / contraction state of the mop arm 42, or the arrow C of the pile constituting the side mop portion 66b may be adjusted. It may be dealt with by adjusting the roughness of the direction.

In the above-described embodiment, as an example of a passenger conveyor to which the cleaning device 10 (cleaning device 10A) is applied, a moving path R inclining the upper floor side floor UF and the lower floor side floor DF as shown in FIG. A general escalator 12 to be connected is shown. In another embodiment, for example, the cleaning device 10 (cleaning device 10A) of the present embodiment is applied to an escalator in which the step 14 temporarily transitions to the horizontal state and then transitions to the stepped state again in the middle of the moving path R. You may. In this case as well, the same effect as that of the above-described embodiment can be obtained. Further, each step 14 that moves on the moving walk R connecting the upper floor UF and the lower floor DF and the moving walk R connecting the entrance side and the exit side of the same floor does not form a step. The cleaning device 10 (cleaning device 10A) of the present embodiment may be applied to a so-called "moving walkway" that moves in a flat state. In this case as well, the same effect as that of the above-described embodiment can be obtained.
