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.
[0007]
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. 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.
[0008]
The details of the moving handrail cleaning device 3 will be described with reference to FIGS.
[0009]
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 mounted in a roll shape of an unused belt-shaped cleaning tool 5, 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 and the moving handrail speed detecting means 9 for detecting whether or not the moving handrail 1 is moved and its moving direction, and the detecting section raising / lowering means 10 for selectively contacting the moving handrail speed detecting means 9 with the moving handrail 1 Cleaning device 5 for rotating the second shaft body 7 in order to wind the belt-shaped cleaning tool 5 on the second shaft body 7 and cleaning for impregnating the cleaning tool 5 with a cleaning liquid or silicon for improving the cleaning effect. Monitoring and storing the state of the liquid supply means 12 and the moving handrail cleaning device 3; Calculation, and it includes at least an operation display unit 14 for displaying an operation unit and a state to command the start operation of the control unit 13 and the moving handrail cleaning device 3 for controlling.
[0010]
The guide bar 15 eliminates the contact surface between the pedestal mat 8i and the belt-like cleaning tool 5 shown in FIG. 4 when the belt-like cleaning tool 5 is updated, and prevents the belt-like cleaning tool 5 from being twisted to smoothly move the belt-like cleaning tool 5 to the second. This is for winding around the shaft body 7.
[0011]
As shown in FIG. 11, the main body case 4 is formed of a stainless steel case 4a and an upper portion with a rubber cover 4b. The main body case 4 covers the moving handrail 1 above the moving handrail 1 in FIG. It has a structure.
[0012]
The belt-shaped cleaning tool 5 uses a nonwoven fabric having a length of 3 m and a width of 11 cm. The unused belt-shaped cleaning tool 5 is wound around the first shaft body 6 of FIG. 2 in a roll shape, and the cleaning liquid supply means 12 and the cleaning tool are pressed. The tip of the belt-like cleaning tool 5 is wound around and attached to the second shaft 7 via the means 8.
