  First, F shown in FIG. 1 is an existing passenger conveyor, and includes a plurality of steps E forming one step of the stairs. The existing step E circulates and moves in an annular shape between the entrance where passengers ride and the exit where the passengers get off. The step E is an outward path traveling from the entrance to the exit, and carries a passenger on the step step surface e. In addition, on the return path from the entrance to the exit, the stepping step surface e is directed downward (toward the ground) as if the top and bottom are reversed, and passes through the passenger conveyor F (inside the truss) f. And come back to the entrance.

  The step E is attached to a chain D with an annular roller d (indicated by a one-dot chain line in FIG. 1) and moves so as to be pulled in the traveling direction of the chain D. Further, when the traveling direction is front and rear, step rollers b are provided on the left and right. The step roller b is guided by a guide rail B attached to the inside f of the passenger conveyor F. That is, the step E is guided by the guide rail B and circulates in the driving direction of the chain D.

  Also, in the interior f, an oil receiving plate A that receives dust from passengers, lubricating oil of the chain D, and the like is disposed facing the step step surface e of the step E on the return path.

Here, 10 shown in FIGS. 1 to 3, a cleaning device of passengers conveyor of the present invention, a footstep type having a main body 1 of the same outer shape as the existing footstep E. Similarly to the existing step E, the main body 1 has a connecting portion that can be connected to the chain D, and a step roller b guided by the guide rail B. That is, it is possible to circulate and move between the entrance and the exit by exchanging (replacement) with the existing step E.

  Further, the main body 1 moves back in the interior f during the climbing operation in which the passenger conveyor F carries passengers from the lower floor side to the upper floor side (when the chain D rotates in the direction of arrow C in FIG. 1). A cleaning brush 2 for cleaning the oil receiving plate A is provided so as to protrude from the step surface 1e on the returning path.

  The cleaning brush 2 is attached to a slide member 5 that reciprocates while being guided by a guide member 4 attached to the main body 1. A weight 6 having an appropriate weight is attached to the slide member 5. The cleaning brush 2 is provided so as to be stored below the step surface 1e in the forward posture when the main body 1 is in the climbing operation (as shown in FIG. 2). Then, when the main body 1 is in the returning posture during the climbing operation (as shown in FIG. 3), the cleaning brush 2 is moved by the weight 6 and the slide member 5 is moved in the direction of the oil receiving plate A to form the step surface 1e. The cleaning brush 2 is provided so as to protrude from the notch 1a. That is, it is attached to the main body 1 so as to be able to protrude and house from the main body 1.

  Moreover, the cleaning brush 2 is provided so that the protrusion angle θ between the cleaning brush 2 and the step surface 1e is 60 ° to 95 ° in the protruding state. When the inclination angle for raising and lowering the passenger conveyor F is 30 °, the protrusion angle is preferably 80 °.

  Here, the principal part plane sectional drawing of the cleaning brush 2 is shown in FIG. When cleaning the oil receiving plate A, the cleaning brush 2 travels so that dusts (dust, foreign matter, etc.) on both the left and right sides of the oil receiving plate A gather at the center in the width direction in the traveling direction (the direction of arrow C). It is formed in a V shape in plan view so that the direction side becomes a concave portion. In addition, the left and right width dimension of the cleaning brush 2 is set slightly larger than the left and right width dimension Wa of the oil receiving plate A, and when protruding, it protrudes so as to spread in the left and right directions and can contact the inner wall of the oil receiving plate A Provided.

  Further, a rail brush 3 capable of cleaning the guide rail B for guiding the step roller b is provided in the vicinity of the two left and right step rollers b of the main body 1. The rail brush 3 is pivotally attached to the main body 1 so as to be swingable so as to clean the front side in the traveling direction of the step roller b. Further, the rail brush 3 has a lower end hair 3a for cleaning the forward guide rail B and a step surface 1e as shown in FIG. 3 when the step surface 1e is upward (in the sky) as shown in FIG. And upper end hair 3b for cleaning the guide rail B for the return path when facing downward (facing the ground).

  Moreover, the flocking of the cleaning brush 2 and the rail brush 3 consists of a stranded wire brush soaked with washing oil.

  Further, a part or the whole of the step surface 1e is formed of a transparent member (for example, an acrylic material). That is, a viewing window (not shown) is formed in the main body 1 so that the inside f can be confirmed from the step surface 1e side when moving on the forward path.

Cleaning of equipment operation as a passenger conveyor of the present invention described above will be described.
First, the two existing steps E are removed from the existing passenger conveyor F. Then, two of the above-Stepping stage type passenger conveyor cleaning apparatus 10 of, in place of the removed existing footstep E, attached so interchanged. That is, as shown in FIG. 1, the passenger conveyor F is brought into a state in which two step type passenger conveyor cleaning devices 10 are incorporated. (In FIG. 1, for ease of explanation, a part of a plurality of existing steps E is shown.) In consideration of work efficiency, it is desirable to replace two adjacent existing steps E.

  Further, a dust suction hose 41 of a cleaning dust suction device 40 capable of collecting dust or the like is disposed on the oil receiving plate A.

  Then, the passenger conveyor F is climbed and operated (operation in the direction of transporting passengers from the lower floor side to the upper floor side). Then, when moving on the forward path (the path where the step E goes from the lower floor side to the upper floor side), as shown in FIG. 2, the step surface 1 e of the main body 1 is in an upward posture, and the cleaning brush 2 has the weight 6. It moves below the step surface e due to its weight and is housed in the main body 1. When the main body 1 pulled by the chain D makes a U-turn so that the top and bottom are turned upside down in the vicinity of the upper floor, the slide member 5 is guided along the guide member 4 to the step surface 1 e side by the weight of the weight 6. The cleaning brush 2 protrudes smoothly and automatically from the notch 1a of the step surface 1e. That is, when moving on the return path, as shown in FIG. 3, the cleaning brush 2 protrudes from the main body 1 so that the oil receiving plate A can be cleaned.

  The cleaning brush 2 protrudes with a protrusion angle θ with respect to the step surface 1 e of 60 ° to 95 °, and reliably contacts the oil receiving plate A. Further, since the cleaning brush 2 is formed in a V shape in a plan view, cleaning is performed so as to sweep away dust or the like (dust or foreign matter) at the corners of the oil receiving plate A to the central portion in the width direction of the cleaning progress direction. To do.

  Further, when the main body 1 makes a U-turn in the vicinity of the lower floor side so that the top and bottom are turned over, the slide member 5 is guided along the guide member 4 in a direction away from the step surface 1e by the weight of the weight 6. . At this time, since the protrusion angle θ with respect to the step surface 1 e is set to 60 ° to 95 °, the cleaning brush 2 moves smoothly and is stored in the main body 1. Then, the forward path is moved in a stored state (a state where it does not protrude from the step surface 1e).

  As shown in FIG. 2, when moving in the forward path, the lower end bristles 3 a of the rail brush 3 move while abutting against the guide rail B for the forward path and cleaning. When the main body 1 makes a U-turn so that the top and bottom turns upside down in the vicinity of the upper floor side, the rail brush 3 swings along the guide rail B for the return path. Thereafter, as shown in FIG. 3, when moving on the return path, the upper end hair 3 b moves while contacting the guide rail B for return path and cleaning.

  That is, after the step type passenger conveyor cleaning device 10 is replaced with the existing step E, the passenger conveyor F is climbed and operated. Then, the oil receiving plate A in the inside f and the guide rail B are automatically cleaned. Further, dust and the like accumulated on the lower floor side of the oil receiving plate A are automatically collected by the dust absorber 40.

  Then, after the step-type passenger conveyor cleaning device 10 is circulated once or twice, the interior f is confirmed from the step surface 1 e side with the viewing window formed in the main body 1. After confirmation, the step type passenger conveyor cleaning device 10 is replaced (returned) to the removed existing step E, and the cleaning operation is completed.

Next, reference examples deeply related to the present invention will be described.
FIG. 5 is a diagram for explaining the usage state of the reference example .
Reference numeral 50 shown in FIG. 5 denotes a passenger conveyor cleaning device according to a reference example of the present invention, which is an installation type installed in an interior f of an existing passenger conveyor F.

F shown in FIG. 5 is an existing passenger conveyor similar to that of the above-described embodiment, and includes a plurality of steps E that are pulled by a chain D with a chain roller d and circulate circularly. (In FIG. 5, a part of the plurality of steps E is shown for explanation.) Further, the step rollers b attached to the left and right of the step E are guided inside the passenger conveyor F (inside the truss). A pair of left and right guide rails B are provided.

  Reference numeral 20 denotes a rotating brush attached to the electric motor, and has two types of cleaning flocking brushes having different lengths in the radial direction of the rotating shaft 20c of the rotating brush 20. One is long long flock 20b. The other is a short flocking 20a that cleans the step roller b in use and is shorter than the other. That is, the rotary brush 20 has a different diameter flocked brush structure having short flocks 20a and long flocks 20b having different outer diameters of the circle of the rotation locus when viewed from the rotation axis direction.

  FIG. 6 shows a plan view of the rotating brush 20. The width dimension Wc in the axial direction of the rotating brush 20 is equivalent to the left-right width dimension Wb of the pair of left and right guide rails B and B (see the two-dot chain line in FIG. 6) provided in the interior f of the existing passenger conveyor F. Set to dimensions.

  Further, the casing 21 has a casing 21 that can collect dust and the like attached to the step roller b and the guide rail B. The casing 21 is provided with a rotating brush 20. The casing 21 communicates with a dust collector 42 that can collect collected dust and the like through a flexible dust collection hose 43.

The operation of the apparatus of the reference example described above and the passenger conveyor cleaning method will be described.
The short flock 20a of the rotary brush 20 attached to the casing 21 is disposed at a predetermined position where the step roller b of the moving step E can be cleaned. Further, when the passenger conveyor F is operated, the step roller b is disposed at a position such that the step roller b faces the rotating brush 20.
Further, the dust collector 42 is disposed in the inside f, and the dust collector 42 and the casing 21 are connected to each other via the dust collection hose 43.

  For example, as shown in FIG. 5, the rotating brush 20 is disposed on the lower floor side of the passenger conveyor F so as to clean the step roller b of the step E returning from the upper floor (on the return path). .

  The passenger conveyor F is climbed and driven (driving step E moves in the direction of arrow C). Then, the step roller b of the step E goes toward the rotation locus of the long flock 20b of the rotating brush 20 one after another. The long flock 20b cleans the guide rail B and the step roller b that enters. Further, the short flocking 20a sequentially cleans the step roller b. The rotating brush 20 collects dust and the like in the casing 21. The dust in the casing 21 is accumulated in the dust collector 42 via the dust collection hose 43.

  The present invention can be modified in design. For example, the cleaning brush 2 and the rail brush 3 are detachably attached to the main body 1 and are used for rough cleaning, finishing cleaning, or the like. A variety of types may be prepared and exchangeable. In addition, when the U-turn is performed so that the top and bottom of the main body 1 is turned over, a regulating member that regulates the swing may be provided so that the rail brush 3 comes into contact with the guide rail B more reliably and is cleaned.

Also, a passenger conveyor cleaning method using the step type passenger conveyor cleaning device 10 of the present invention and the installation type passenger conveyor cleaning device 50 of the reference example in combination is possible. At this time, dust accumulated by the rail brush 3 is collected in the casing 21 by the rotating brush 20. Alternatively, the dust collector 42 may be used in place of the dust collector 40, and dust etc. on the oil receiving plate A may be collected by the dust collector 42.

  As described above, the present invention is provided with the cleaning brush 2 for cleaning the oil receiving plate A installed in the inside f of the passenger conveyor F in the main body 1 having the same outer shape as the step E of the passenger conveyor F. The oil receiving plate A can be cleaned easily and quickly by replacing the existing step E. It is not necessary for a person to enter the interior f and clean it, and it can be cleaned safely.

  The cleaning brush 2 is attached to the main body 1 so as to be able to protrude and house from the main body 1 and the protrusion angle θ between the main body 1 and the step surface 1e is 60 ° to 95 °. 2 can reliably contact the oil receiving plate A at an appropriate angle for cleaning. In addition, during the U-turn, it is possible to make it smooth without protruding / storing.

  Further, since the cleaning brush 2 is formed in a V shape in a plan view, dust and the like on the oil receiving plate A is prevented from escaping backward in the traveling direction of the cleaning brush 2 and in the left-right direction, and is reliably cleaned. It is possible to collect dust by sweeping (wiping) in the direction.

  Moreover, since the rail brush 3 which can clean the guide rail B which guides the step roller b attached to the step E is provided in the main body 1, the guide rail B can be cleaned together with the cleaning of the oil receiving plate A.

  Further, a cleaning device 10 for a step type passenger conveyor provided with a cleaning brush 2 for cleaning an oil receiving plate A installed in an inside f of the passenger conveyor F on a main body 1 having the same outer shape as the step E of the passenger conveyor F; Since one or two of the steps E are replaced and the passenger conveyor F is climbed and operated to clean the oil receiving plate A, the inside f can be cleaned without removing all the existing steps E. In addition, since the oil receiving plate A is cleaned in the same state as the steps E are all attached, dust and dirt are not scattered so as to wind up from the inside f, and the surroundings (in the floor or the store) Can be cleaned without getting dirty. Moreover, since garbage etc. do not scatter around, it can work hygienically. Further, since one or two steps E can be removed, it is possible to reduce a setup work for securing a place for temporarily placing the removed steps E and arranging a curing mat or the like. Moreover, automatic cleaning can be easily performed by operating the existing passenger conveyor F. That is, other work can be performed during cleaning, and work efficiency is improved.

  There is a rotating brush 20 that can clean the guide rail B that guides the step roller b attached to the step E of the passenger conveyor F, and the step roller b, and can collect dust collected by the rotating brush 20. Since the dust collecting device 42 is provided and the rotary brush 20 has a different diameter flocking brush structure having short flocking 20a and long flocking 20b, the step roller b and the guide rail B can be cleaned. Moreover, the step roller b can be reliably cleaned with the short flocking 20a and the long flocking 20b.

  The rotating brush 20 is installed in the vicinity of the guide rail B that guides the step roller b attached to the step E of the passenger conveyor F, and the step roller b and the guide rail B are cleaned. The step rollers b can be automatically cleaned sequentially so that b comes toward itself.
