[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 and vertical surface of steps as the steps move up and down. Regarding improvement of tools.

[Prior Art] Figure 4 shows the configuration of a general passenger conveyor, in which 1 is a passenger conveyor, 2 is a glass inner plate, 3 is an inner deck, 4 is a skirt guard, and 5 is a passenger conveyor.
6 is a floor plate, 6 is a step having a cleat groove, 6a is a tread surface of this step 6, 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, when the installation is completed, the steps 6
need to be cleaned. Further, even after that, the steps 6 may be contaminated with garbage and dust carried by passengers and may accumulate thereon, which is unfavorable in terms of product design and functionality, so the steps 6 must be cleaned regularly.

By the way, in the past, this cleaning method was
This is carried out by a man conveyor step cleaning machine as shown in No. 36575 (Utility Model Publication No. 148780/1983). FIG. 5 is a side view showing an example of such a conventional passenger conveyor step cleaning machine. In the figure, 8 is a man conveyor step cleaning machine attached to the inner deck 3 of the man conveyor 1, and it has a mounting part 9 to the inner deck 3 and a shaft 1 to this mounting part 9.
The cleaning tool 13 is comprised of a swingable operating arm 11 whose base end is pivotally connected via a support arm 12 and a cleaning tool 13 attached to the distal end of the operating arm 11 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.

[Problems to be solved by the invention] As described above, in the conventional man conveyor step cleaning machine, the resin brush 14 of the cleaning tool 13 moves over the tread surface 6a and the vertical surface 6b of the step 6 as the step 6 moves. The resin brush 14 is cleaned by sliding relative to each other, but since the resin brush 14 is composed of thin resin wires bundled with wire or the like, it takes time to manufacture, and the diameter and set number of thin resin wires are limited. Not only does the length tend to increase, but the thin resin wire cannot withstand the pressing force caused by the movement of the steps 6 and the sliding friction force of the resin brush 14 itself, as shown in FIGS. 8 and 9. As shown in FIG. There was a drawback that the tip of the step 14 sometimes slid on the step 6 without hitting all the parts, resulting in insufficient cleaning.

Furthermore, if the resin brush 14 of the cleaning tool 13 breaks, the entire brush must be replaced, which poses a problem of poor workability and economy.

In view of the above points, the present invention has been developed so that when the cleaning tool slides on the treads and elevations of steps, the brush portion can be reliably brought into sliding contact along the cleat shape of the treads and elevations. To provide a man conveyor step cleaning machine which does not leave uncleaned parts and allows only sliding parts to be replaced.

[Means for Solving the Problems] In the man conveyor step cleaning machine of the present invention, the cleaning tool is formed from a support plate and sheep fur having a wool portion on the sliding surface formed to cover the support plate. The support plate and the sheep fur are bonded to each other through a removable adhesive cloth.

[Function] In the present invention, the wool is reliably slid closely along the tread and elevation shape of the step having cleat grooves, so there are no unslided or uncleaned areas, and sufficient cleaning is performed. be able to. In addition, since the support plate and the sheep fur are connected via adhesive cloth, it is easy to separate them, and furthermore, it is possible to change the position of the sliding part of the sheep fur by simply shifting the bonding position. When replacing, only the sheep fur can be replaced, improving work efficiency and economic efficiency.

[Embodiment] 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, reference numeral 20 denotes a cleaning tool according to the present invention that is attached to the tip of an operating arm (not shown) via a support arm. Support plate 2 on which comb-like protrusions 21a are formed
1, and a sheep fur 22 attached to the support plate 21 so as to cover the protrusion 21a of the support plate 21. The support plate 21 has a plurality of holes 1 on its base end side.
7 is bored, and the support arm is attached to the support arm by a bolt inserted through the hole 17. Further, on the support plate 21, two strips of adhesive cloth 23a, 23b, 2 are provided on each of the front and back surfaces on the tip side of the hole 17 and extend in the width direction at a predetermined pitch.
3c, 23d are provided, and the distance between each adhesive cloth 23b, 23c located on the tip side, that is, from the adhesive cloth 23b on the front side to the protrusion 2 of the support plate 21.
The distance from the tip of 1a to the adhesive cloth 23c on the back side is also set to the same pitch as above. The above-mentioned sheep fur 22 has a wool part 22a that is flexible, elastic, dense, and has a long pile, and a skin part 22b that has good adhesion. , each adhesive cloth 2 on the support plate 21 side
3a, 23b, 23c, 23d, and four strips of adhesive cloth 24a, 2 extending in the width direction and spaced apart from each other by the same pitch.
4b, 24c, and 24d are provided, and are adapted to be removably engaged and bonded 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.

The man conveyor step cleaning machine of the present invention constructed as described above has the central part of the back surface of the sheep fur 22 brought into contact with the protrusion 21a at the tip of the support plate 21, and both ends thereof are folded back, and each adhesive cloth part is attached. As shown in FIG. 1, the cleaning tool 20 is constructed by engaging and bonding. When the cleaning tool 20 configured as described above is attached to the support arm at the tip of the operating arm (not shown) and the passenger conveyor is driven in the direction of arrow A, the operating arm follows the movement of the steps 6 and moves in the direction of arrow B (the direction of arrow B). 5), 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 repeats this operation to remove dust and dirt that has adhered to and accumulated on the step 6. Remove waste and clean. 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 from the rear, the protrusion 21a of the support plate 21
Since a uniform pressing force is applied by the cleat groove, the wool filling the cleat groove conforms well to the shape of the cleat groove and slides like a bundle, preventing dust from adhering to the steps 6 during or after the installation work. It is possible to sufficiently remove and clean the accumulation of dirt, etc.

Further, the cleaning tool 20 according to the present invention has a function that deteriorates due to frequency of use, such as loss of elasticity, at the sliding contact portion with the step 6 in the wool portion 20a or the leather portion 22b of the sheep fur 22. However, in such a case, the initial function can be obtained simply by shifting the attachment position of the sheep fur 22 to the support plate 21, so that durability can be improved. That is, the pitch between each adhesive cloth 24a, 24b, 24c, 24d on the sheep fur 22 side and each adhesive cloth 23a, 23b, 2 on the support plate 21 side.
Since the pitch between 3c and 23d is set to the same pitch, for example, the adhesive cloth 24a and 23b, 24
Either the engagement position is shifted one step at a time from the surface side of the support plate 21, as in b and 23c, 24c and 23d, or the adhesive cloth 24d and 23c, 24c and 23
b, 24b and 23a, the engagement position is shifted one step at a time from the back side of the support plate 21, etc.
It is easy to change the position of the sliding contact part.

In addition, in the above embodiment, the support plate 21 and the sheep fur 22
For example, it is possible to provide one adhesive cloth that engages the entire back surface of the sheep fur 22, or one that engages the entire surface of the support plate 21. It is also possible to provide an adhesive cloth, and in such a case, the number of moving parts increases even more, making it possible to use the device many times.

Further, other adhesive means such as double-sided tape may be used for the adhesive cloth, and in such a case, the same effects and effects as described above can be expected.

Furthermore, 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 fur of other animals or fur of other animals may be used as long as it has a similar effect. Other fur-like coverings, such as fabrics with long fiber piles, may also be used, and in such cases, the same effects as in the above embodiments can be achieved.

[Effects of the invention] As described above, according to the invention, the cleaning tool is formed from a support plate and a fur-like covering having a raised portion on the sliding surface formed to cover the support plate, and Since the support plate and the fur-like covering are bonded via a removable adhesive layer, it follows the shape of the cleat grooves on the treads and elevations of the steps and provides good brushing action, allowing for sufficient cleaning. Do it,
Costs and labor for additional cleaning, etc. can be saved, and the position of the sliding contact portion of the fur-like covering can be changed, which has the effect of significantly improving durability, workability, and economic efficiency.
