Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a man conveyor step cleaning machine, and more specifically, a cleaning machine that cleans by sliding on the tread surface and vertical surface of a step as the step moves up and down. Regarding improvement of tools.

[Conventional technology]

Figure 4 shows the configuration of a general passenger conveyor. In the figure, 1 is the passenger conveyor, 2 is the glass inner plate, 3 is the inner deck, 4 is the skirt guard, and 5 is the
6 is a floor plate, 6 is a step having a cleat groove, 6a is a tread of this step 8, 6b is an elevation of the step 6, and 7 is a handrail.

The passenger conveyor 1 constructed in this manner is provided with a large number of individual steps 6 connected together, but the tread surface 6a and vertical surface 6b of the steps 6 are free from dust adhesion and debris during the installation work. Therefore, it is necessary to clean and sweep the steps 6 when the installation is completed. Further, even after that, trash and dust carried by passengers may adhere to and accumulate on the steps 6, which is undesirable in terms of product design and functionality, so it is necessary to periodically clean the steps 6.

By the way, in the past, this cleaning method was
This is done by a man conveyor step cleaning machine as shown in No. 36575. FIG. 5 is a side view showing an example of such a conventional passenger conveyor step cleaning machine. In the figure, 8 is the man conveyor 1
This is a man conveyor step cleaning machine attached to the inner deck 3, and the attachment part 9 to the inner deck 3 is
, a swingable actuating arm 11 whose base end is pivotally attached to the mounting portion 9 via a shaft 10 , and the actuating arm 1
1 and a cleaning tool 13 attached to the tip of the cleaning tool 1 via a support arm 12.

However, the cleaning tool 13, as shown in FIG.
It consists of a steel support 15 with resin brushes 14 bundled together, or a wooden support 16 with resin brushes 14 bundled together as shown in FIG. The support arm 12 is clamped and fixed between the support arm 12 and a support metal 19 disposed opposite thereto by means of a bolt 18a and a nut 18b (FIG. 5).

Next, based on FIG. 5, the operation of the conventional passenger conveyor step cleaning machine having the above configuration will be explained. First, the mounting part 9 of the passenger conveyor step cleaning machine 8 is attached and fixed to the inner deck 3 of the passenger conveyor 1, and the operating arm 11 swings in the direction of arrow B following the movement of the step 6 in the direction of arrow A (downward direction). installed so that it can be
Drive the passenger conveyor 1. The cleaning tool 13 at the tip of the operating arm accompanying the above-mentioned swinging motion of the operating arm 11 due to this drive has its resin brush 14 on the vertical surface 6b of the step 6.
, and then the tread surface 6a, and thereafter, this operation is repeated to remove and clean dust adhering to the step 6, accumulation of dirt, etc. during the installation work period.

[Problem that the invention seeks to solve]

As described above, in the conventional man conveyor step cleaning machine, as the step 6 moves, the resin brush 14 of the cleaning tool 13 slides relatively on the tread surface 6a and the vertical surface 6b of the step 6, thereby cleaning the step. However, since the resin brush 14 is composed of resin wires bundled with wire or the like, the diameter and set number of thin resin wires are limited, and the length tends to be long, as well. Pressing force and resin brush 14 due to movement of
The thin resin wire cannot withstand the sliding friction force of itself, and as shown in FIGS. 8 and 9, it bends or breaks, and the resin brush 14 cannot fully enter the cleat groove. As shown on the right side of Figure 9, the thin resin wire may be bent or folded in its entirety, causing the tip of the resin brush 14 to slide on the step 6 without hitting all of the wires, resulting in insufficient cleaning. It was hot.

In view of the above-mentioned points, when the cleaning tool slides on the tread surface and the vertical surface of the step, the brush portion can be reliably brought into sliding contact along the cleat shape of the tread surface and the vertical surface, To provide a man conveyor step cleaning machine that does not leave uncleaned areas.

[Means for solving problems]

In the passenger conveyor step cleaning machine of the present invention, the cleaning tool is composed of a support plate and a sheep fur having a wool portion on the sliding surface formed to cover the support plate.

[Function] In the present invention, since the wool portion is reliably slid closely along the tread and elevation shape of the step having cleat grooves, sufficient cleaning is performed without leaving any unslidable or uncleaned areas. be able to.

〔Example〕

Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS. 1 to 3, in which parts corresponding to conventional ones are denoted by the same reference numerals. In the figure, 20 is the operating arm 11
The support plate 21 is attached to the tip of the step via the support arm 12 and has a comb-like protrusion 21a formed on the edge of the step side according to the present invention along the shape of the cleat groove of the step 6.
(Fig. 2), and this protrusion 2 is attached to this support plate 21.
1a and a sheep fur 22 attached to cover it. The support plate 21 has a plurality of holes 17 drilled on its base end side for attachment to the support arm 12,
Bolt 18a and nut 18 inserted into this hole 17
b, so that the support arm 12 is clamped and fixed between the support arm 12 and a support metal 19 disposed opposite thereto. Further, the support plate 21 is provided with a plurality of holes 23 for fixing the sheep fur 22 on the distal end side of the holes 17, and the support plate 21 and this A pair of presser plates 25, 25 arranged oppositely on the upper and lower surfaces, respectively.
Both end edges of the sheep fur 22 can be clamped and fixed between the two ends. The above-mentioned sheep fur 22 has a wool part 22 that is flexible, elastic, dense and has long piles.
a and a skin portion 22b with good adhesion,
It is designed to be attached to the support plate 21 with the wool portion 22a on the front side, that is, on the sliding contact side. Since the configuration other than the above is the same as the conventional one, the explanation thereof will be omitted.

In the passenger conveyor step cleaning machine of the present invention constructed as described above, when the mounting portion 9 is attached and fixed to the inner deck 3 of the passenger conveyor 1 and the passenger conveyor 1 is driven in the direction of arrow A, the actuating arm 11 moves to the step 6. Following the movement, the cleaning tool 20 swings in the direction of arrow B, and the cleaning tool 20 at its tip slides on the vertical surface 6b of the step 6, then slides on the tread surface 6a, and thereafter repeats this operation to clean the step 6.
Remove and clean the dust, sludge, etc. that have adhered to or accumulated on the surface.
At this time, the wool part 22a used as the sliding material of the cleaning tool 20 sequentially fills the cleat grooves of the tread surface 6a and the vertical surface 6b, and the protrusion part 21a of the support plate 21 from the rear. As a result, a uniform pressing force is applied, so the wool that fills the cleat groove conforms well to the cleat groove shape.
By sliding like a bundle, it is possible to sufficiently remove and clean dust adhering to the steps 6, dirt deposits, etc. during or after the installation work.

By the way, the support plate 21 can be made of various materials such as wood or iron, but the support plate 21 can be made of an elastic material such as resin.
An elastic change of 1 can be added.

In the above embodiment, sheep fur 22 is used as the sliding material of the cleaning tool 20, but the material is not limited to this, and other animal fur or long fur can be used as long as it has a similar effect. Fabrics with fiber pile, etc.
Other fur-like coverings may be used, and the same effects as in the above embodiments can be achieved in such cases as well.

〔Effect of the invention〕

As described above, according to the present invention, the cleaning tool is composed of the support plate and the fur-like covering having the raised portion on the sliding surface formed by covering the support plate. It follows the shape of the cleat grooves on the surface well and provides a good brushing action, allowing for sufficient cleaning and saving the cost and labor of additional cleaning.
