DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step cleaning device for a passenger conveyor such as an escalator and an automatic line.

[0002]

2. Description of the Related Art Conventionally, in a step cleaning device for a passenger conveyor, a brush which abuts on a bottom of a cleat groove of a step is attached to a fixed part side such as a frame of a truss structure or a beam structure, and a movable part side such as a step is fixed. By moving, the bottom of the step inside the cleat groove is cleaned.

[0003]

In the above-mentioned conventional step cleaning apparatus for a passenger conveyor, the brush tip is rubbed by the bottom of the cleat groove of the step on which the brush moves, and the brush tip is curved. However, there is a problem that the inner surface of the step does not contact the inner bottom of the cleat groove, and the inner bottom of the cleat groove of the step cannot be cleaned.

An object of the present invention is to provide a passenger conveyor step cleaning device which can solve the above problems.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide a movable part having a plurality of endlessly connected steps, a step and a handrail which moves synchronously, and a fixed part such as a frame for supporting the movable part. A step cleaning device for a passenger conveyor, wherein a comb-shaped cleaning member fitted to a cleat groove of the step is provided on the fixed portion side, wherein a comb-tooth portion of the comb-shaped cleaning member is made an elastic body; Is set longer than the depth of the cleat groove.

According to this configuration, even if the tip of the comb tooth of the comb-shaped cleaning body is curved, the tip of the comb tooth does not separate from the inner bottom of the cleat groove, and the inner bottom of the cleat groove becomes the tip of the comb tooth. Rubs semi-permanently for cleaning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a passenger conveyor step cleaning apparatus according to the present invention will be described below with reference to the drawings.

In FIG. 1, a passenger conveyor 1 comprises a plurality of endlessly connected steps 2, a movable part A such as a handrail 3 which moves in synchronization with the steps 2, and a frame 4 for supporting the movable part A. And the like. The upper machine room 1 a of the frame 4 is provided with an upper terminal gear 5 and a driving device 6. In the lower machine room 1b of the frame 4, a lower terminal gear 7 and a driving device 6 are provided. The frame 4 has a truss structure or a beam structure. A guide rail 8 that guides a guide roller 7 provided on the step 2 and forms a part of the fixed portion B is provided in the frame 4. Step 2 in frame 4
Below, is provided an oil pan 9. Step 2
Is rotatably moved between the upper machine room 1a and the lower machine room 1b while being guided by the guide rail 8 by the step chain driven by the drive unit 6.

A step cleaning device 10 is fixed to the guide rail 8 by a plurality of fixing bolts 11 and 11a. The step cleaning device 10 includes a mounting frame 12 made of a conductive steel material and a comb-shaped cleaning body 1 fixed to the mounting frame 12.
3 The comb-shaped cleaning body 13 has a comb-tooth portion 14 for rubbing the inner bottom 16a of a large number of cleat grooves 16 formed on the tread surface of the step 2, and the comb-tooth portion 14 is attached and fixed to the mounting frame 12. And a fixing frame 15 made of conductive steel material. As shown in FIGS. 4 and 5, the comb teeth portion 14 of the comb-shaped cleaning body 13 has a structure in which a large number of round rod-shaped elastic bodies 14a are arranged in a line.
The length L1 of the step 4a is set longer than the depth L2 of the cleat groove 16 of the step 2. The elastic body 14a is made of rubber.

In the above configuration, when the step 2 is driven, the inner bottom 16a of the cleat groove 16 is strongly rubbed by the elastic body 14a of the comb tooth portion 14, and dust attached to the inner bottom 16a is removed. At this time, the elastic body 14a is bent, but since the length L2 of the elastic body 14a is longer than the depth L2 of the cleat groove 16, the distal end portion of the elastic body 14a does not separate from the inner bottom 16a of the cleat groove 16. , Elastic body 1
The inner bottom 16a of the cleat groove 16 is constantly rubbed by 4a.

FIG. 6 shows a modification of the present invention. In the comb-shaped cleaning body 130 shown in FIG.
40b. Due to the inclined surface 140b, the contact area between the comb tooth portion 140 and the inner bottom 16a of the cleat groove 16 can be increased, so that the inner bottom 16
a is efficiently cleaned.

The elastic members 14 and 140a have a round bar shape, but are not limited thereto. Elastic bodies 14, 140
If a is a rubber plate, the inner bottom 1 in the cleat groove 16
The cleaning of 6a is performed more efficiently.

[0013]

As described above, according to the present invention, since the length of the elastic body is longer than the depth of the cleat groove, it is possible to prevent the brush tip from coming into contact with the inner bottom of the cleat groove in a short time. As a result, a step cleaning device for a passenger conveyor that can efficiently clean the bottom of the step cleat groove for a long time can be obtained.
