Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a moving handrail cleaning device for a passenger conveyor provided in a passenger conveyor such as an escalator.
[0002]
[Prior art]
Conventionally, in passenger conveyors such as escalators, for example, as described in JP-A-5-24782, a cleaning tool that comes into sliding contact with a moving handrail is provided with means for bringing the moving handrail into contact with the moving handrail. Accordingly, there has been proposed an automatic cleaning device for a moving handrail that automatically cleans the surface of the moving handrail with the cleaning tool and automatically updates the cleaning tool.
[0003]
[Problems to be solved by the invention]
However, in the conventional automatic handrail cleaning device for passenger conveyors, the pressing member has a fixed shape of an inverted C shape, or has an inverted U shape configuration by a rotating screw feed system.
[0004]
In the case of the former method, when winding the belt-shaped cleaning tool of the used part, the cleaning tool is smoothly wound around the winding shaft body as long as the cleaning tool is not lifted from the moving handrail and is not completely lifted from the pressing member. Since this is impossible, a separate member is required to correct this, and the entire apparatus becomes complicated. In the case of the latter method, there are many disadvantages such as an increase in the number of parts that require a power source.
[0005]
The object of the present invention is that it has a simple structure but does not have the above-mentioned drawbacks, and forms a reverse C shape when cleaning a moving handrail, and becomes a substantially horizontal shape when the cleaning tool is renewed so that the belt-like cleaning tool can be smoothly wound. It is providing the moving handrail cleaning apparatus of a passenger conveyor.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention comprises means for selectively bringing a cleaning tool in sliding contact with a moving handrail of a passenger conveyor into contact with the moving handrail, and the moving handrail is moved by the cleaning tool as the moving handrail moves. In the moving handrail cleaning device of the passenger conveyor that automatically cleans the surface of the passenger and automatically updates the cleaning tool, the cleaning tool is pulled away from the moving handrail when the cleaning tool is automatically updated, and again becomes a moving handrail when the update is completed. The pressing member has a reverse C-shape so that the belt-shaped cleaning tool of the used portion is smoothly wound around the winding shaft when the cleaning tool is automatically updated. It is said.
The present invention further comprises means for selectively bringing a cleaning tool that comes into sliding contact with a moving handrail of a passenger conveyor into contact with the moving handrail, and the surface of the moving handrail is automatically made by the cleaning tool as the moving handrail moves. In the moving handrail cleaning device of the passenger conveyor that automatically cleans and updates the cleaning tool, the cleaning tool is separated from the moving handrail when the cleaning tool is automatically updated, and is again pressed against the moving handrail when the update is completed. In addition, when the pressing member whose shape is changed substantially horizontally during the automatic renewal of the cleaning tool returns to the moving handrail cleaning state again, it automatically returns to a reverse C shape only by the pressing force of the pressing member. .
[0007]
According to such means, in order to form the cleaning tool pressing member slidably in contact with the moving handrail of the passenger conveyor into a reverse C shape, or to automatically and repeatedly change to a substantially horizontal or slightly middle-high shape, the lever principle is applied. Since it is operated by the pressing force between the cleaning tool pressing members, the structure is simple, the cleaning function of the moving handrail surface, the smooth winding property when the cleaning tool is updated, and the shape is compact. have.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the form of the handrail cleaning device for passenger conveyors of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is a side view of a passenger conveyor equipped with a passenger conveyor moving handrail cleaning device according to an embodiment of the present invention.
[0010]
The moving handrail 1 is configured to be movable along the guide 2 and moves in synchronization with an endless step (not shown). A moving handrail cleaning device 3 is provided at a portion facing the surface of the moving handrail 1, and details of the moving handrail cleaning device 3 are shown in FIG.
[0011]
FIG. 2 is a side view showing a moving handrail cleaning device for a passenger conveyor according to an embodiment of the present invention showing an enlarged main part of FIG.
[0012]
As shown in FIG. 2, the moving handrail cleaning device 3 installed on the passenger conveyor includes a main body case 4 having an upper surface opening, a first shaft body 6 in which an unused belt-shaped cleaning tool 5 is mounted in a roll shape, and belt-shaped cleaning. A cleaning tool pressing means comprising a second shaft body 7 that winds up a used part of the tool 5 and a part of the unused portion of the belt-like cleaning tool 5 that presses a part of the moving handrail 1 and makes contact with the surface of the moving handrail 1. 8, a moving handrail speed detecting means 9 for detecting whether or not the moving handrail moves, a moving direction of the moving handrail, a cleaning liquid tank 10 for impregnating the cleaning tool 5 with a cleaning liquid such as silicon liquid for improving the cleaning effect, and a moving handrail Control means 11 that monitors, stores, calculates, and controls the state of the cleaning device 3, an operation unit that instructs operation start of the moving handrail cleaning device 3, and an operation display unit 12 that displays the state are provided at least.
[0013]
The pressing means 8 is disposed between the first shaft body 6 and the second shaft body 7 as shown in FIG. On the second shaft body 7 that winds up the used portion of the belt-shaped cleaning tool 5, the used belt-shaped cleaning tool 5 including the clutch mechanism 13 that prevents reverse rotation of the shaft body is wound on the second shaft body 7. Cleaning tool updating means 14 for rotating the second shaft body 7 is provided.
[0014]
3 to 6 are main part structural views showing an embodiment of the belt-like cleaning tool updating means of the present invention, and FIG. 7 is a reference view showing a conventional example.
[0015]
The structure of the pressing mechanism 8 of the present plan will be described in detail. As shown in FIGS. 3 to 5, the pressing mechanism 8 is held by guides 23 and 24 inside a pressing holder 22 fixed on the pressing support base 21, and There is a pressing shaft 25 fixed to the guide 24 with a screw. Further, the pressing shaft 25 is supported by a pin 27 from a receiving metal 26 fixed to the guide 24, and a sponge cushion 33 is attached to the upper surface, and separated into two bodies on the left and right. The pressing table (1) 29 and the pressing table (2) 31 are configured to press the belt-shaped cleaning tool 5 against the moving handrail 1 by a pressing spring 28 set between the guides 23 and 24.
[0016]
Further, a cushion holder 34 is fixed to the central portion of the cushion 33, and both ends thereof are bonded and fixed to the pressing table (1) 29 and the pressing table (2) 31, respectively, and are rotatably supported by pins 27. The protrusion (1) 30 of the pressing base (1) 29 and the protrusion (2) 32 of the pressing base (2) 31 can be moved up and down via the cushion holder.
[0017]
Further, the vertical movement drive of this pressing mechanism is performed via a roller 44 supported by a pin 43 at the lower end of the guide 23 by the rotation of a cam 42 fixed to the shaft of the motor 40 attached to the motor support bracket 41. Done. In addition, a means (not shown) for detecting the upper limit position and the lower limit position of the cam 42 is incorporated in the pressing mechanism.
[0018]
Due to such a configuration, when the operation of the moving handrail 1 of the passenger conveyor is started, an operation start command is received from the moving handrail speed detecting means 9, and the motor 40 rotates and pushes the cam 42 to the upper limit position. The belt-shaped cleaning tool 5 is pressed against the moving handrail 1 through the cushion 33 by the stand.
[0019]
When cleaning the moving handrail 1, it is necessary to clean not only the flat part but also the side part. In this proposal, as a method of pressing the belt-like cleaning tool 5 against the side part, a lever using a pressing force as shown in FIG. The principle is applied. That is, the pressing base is separated into two bodies, which are engaged with each other by the projections 30 and 32 and can be rotated by the pin 27.
[0020]
Therefore, when the pressing force by the cam 42 is not applied, the pressing table is opened by its own weight as shown in FIG. 5, but the cam 42 starts to rise. The reaction force from the moving handrail 1 is applied to the cushion holder 34 via the cushion 33 and pushes the pressing table protrusions (1) 30 and (2) 32. As a result, each of the pressing bases (1) 29 and (2) 31 that can be rotated by the pins 27 generates a moment of [a × p] and is deformed into an inverted C shape so as to wrap the moving handrail 1. Then, at the upper limit point of the cam 42, the belt-shaped cleaning tool 5 can be pressed to the side surface of the moving handrail 1 in a completely inverted C shape.
[0021]
Now, when the cleaning time that has been set has elapsed and the cleaning device 5 has become dirty, the cleaning surface needs to be pulled away from the moving handrail 1 when the cleaning surface is updated. When lowered to the lower limit point, the pressure table is opened as shown in FIG. 5 by the respective weights of the pressure tables (1) 29 and (2) 31. What is important here is that the upper surface of the cushion 33 becomes substantially horizontal or slightly middle and high when the pressing table is lowered, and therefore the belt-like cleaning tool 5 can be smoothly wound around the second shaft body 7.
[0022]
This is because, in the case of a fixed inverted C-shaped press stand as shown in FIG. 7, the belt-like cleaning tool 5 to which tension is applied when the belt-like cleaning tool 5 is wound around the second shaft body 7 falls into the recessed portion 35. It cannot wind up smoothly, and an auxiliary tool (not shown) such as a parallel support plate is required to prevent this.
[0023]
【The invention's effect】
As described above, in the belt-like cleaning tool pressing mechanism of the passenger conveyor moving handrail cleaning device of the present invention, the following effects can be expected.
[0024]
(1) The pressing of the belt-shaped cleaning tool to the side surface portion of the moving handrail can have a reverse C-shaped performance similar to that of the fixed type without using a complicated structure such as a screw feed method.
[0025]
(2) When winding the belt-shaped cleaning tool of the used part, the pressure cushion can be kept almost horizontal or slightly middle and high by simply releasing the pressing force. The body can be wound smoothly.
[0026]
(3) Since the system uses few components and uses only pressing force, operation reliability is high.
