Description

[Detailed Description of the Invention] [Industrial Application Field] 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.

[Prior Art] Figure 4 shows the configuration of a general passenger conveyor, in which (1) is the passenger conveyor, (2) is the glass inner plate, and (3) is the passenger conveyor.
) is the inner deck, (4) is the skirt guard, (5) is the floorboard, (8) is the step with a cleat groove, (6a) is the tread of this step (6), and (6b) is the elevation of the step (6). ,(
7) is a handrail.

The passenger conveyor (1) is constructed in this way.

A large number of individual steps (6) are connected, and the tread (6a) and elevation (8b) of these steps (6)
) may become dirty due to adhesion of dust or accumulation of sludge during the installation period, and for this reason, the steps (6
) need to be cleaned. In addition, even after that, the steps (6) must be cleaned regularly because trash and dust carried by passengers may adhere to and accumulate on the steps (B), which is undesirable in terms of product design and functionality.

By the way, in the past, this cleaning method was
This is done by a man conveyor step cleaning machine as shown in No. 75. Figure fJS5 is a side view showing an example of such a conventional passenger conveyor step cleaning machine. In Figure 1, (8) is a passenger conveyor step cleaning machine attached to the inner deck (3) of the passenger conveyor (1). , an attachment part (9) to the inner deck (3), a swingable actuation arm (11) whose base end is pivotally connected to the attachment part (9) via a shaft (10), It consists of a cleaning tool (13) attached to the tip of an arm (11) via a support arm (12).

However, the cleaning tool (13) is a steel support (15) made of resin brushes (14) bundled together as shown in FIG. 6, or a steel support tool (15) made of resin brushes (14) bundled together as shown in FIG. It consists of wooden supports (16), these supports (15), (1
Bolts (1) inserted into the multiple holes (17) drilled in B)
8a) and oak) (18b), the support arm (1
2) and a supporting metal (19) placed opposite thereto (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, attach the mounting part (9) of the man conveyor step cleaning machine (8) to the man conveyor (1).
The operating arm (11) is installed so that it can swing in the direction of arrow B following the movement of the steps (6) in the direction of arrow A (downward direction), and
) to drive. As the operating arm (11) swings due to this drive, the cleaning tool (13) at the tip of the operating arm slides its resin brush (14) on the vertical surface (6b) of the step (6),
Next, the tread surface (8a) is slid, and this operation is repeated thereafter to remove and clean dust adhering to the step surface (6), accumulation of waste, etc. during the installation work period.

[Problems to be Solved by the Invention] As described above, in the conventional passenger conveyor step cleaning machine, the resin brush (14) of the cleaning tool (13) is removed as the step (6) moves.
) slides relatively on the tread (6a) and vertical surface (6b) of the step (6) to clean them, but the resin brush (
14) is constructed by bundling thin resin wires with wire, etc., so the diameter and set number of the thin resin wires are limited, and the length tends to be long. The thin resin wire cannot withstand the accompanying pressing force and the sliding friction force of the resin brush (14) itself, and as shown in FIGS. 8 and 9, it bends or breaks, causing the resin brush (14) to cleat. If the resin brush (14) does not fully enter the groove, and in extreme cases, the entire thin resin wire is bent or broken, as shown on the right side of Fig. 9, the tip of the resin brush (14) may not reach the step (6). This has the disadvantage that cleaning may be insufficient as it may slide on the surface.

In view of the above points, when the cleaning tool slides on the tread surface and the vertical surface of the step, the brush part 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 the Problems] In the passenger conveyor step cleaning machine of the present invention, the cleaning tool is composed of a support plate and a wool part having a wool part on the sliding surface formed to cover the support plate. It is.

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

[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, (20) is a cleaning tool according to the present invention that is attached to the tip of the operating arm (11) via the support arm (12), and the cleaning tool (20) is attached to the tip, that is, the edge on the step side. A comb-shaped protrusion (
a support plate (21) (Fig. 2) on which 21a) is formed;
It is composed of a wool part (22) attached to the support plate (21) so as to cover the protrusion part (21a) of the support plate (21). The support plate (21) has a plurality of holes (17) drilled on its base end side for attachment to the support arm (12).
(18a) and Natsuto (+, 8b)
) between the support arm (12) and a support plate (19) disposed opposite thereto. A plurality of holes (23) for fixing the wool part (22) are provided on the side, and the support plate (21) and its upper A pair of presser plates (25) are arranged facing each other on the lower surface side.

(25), both end edges of the wool portion (22) can be fixed to the tube. The wool part (22) is
Soft, elastic, dense and long wool (22
a) and a skin part (22b) with good adhesion,
The wool part (22a) can be attached to the support plate (21) with the front side, that is, 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 configured as described above, the attachment part (9) is attached and fixed to the inner deck (3) of the passenger conveyor (1), and the passenger conveyor (1,) is moved in the direction indicated by the arrow A.
When driven in the direction, the operating arm (11) follows the movement of the step (6) and swings in the direction of arrow B, and the cleaning tool (2
0) slides on the vertical surface (6b) of the step (8), then slides on the tread (8a), and thereafter repeats this operation to move the step (6).
) to remove accumulated dust, sludge, etc. At this time, the wool part (
22) sequentially fills the wool portion (22a) into the cleat grooves of the tread surface (8a) and the vertical surface (6b), and applies a uniform pressing force from the rear by the protrusion (21a) of the support plate (21). Because of this, the wool that fills the cleat groove conforms well to the shape of the cleat groove and slides like a bundle, preventing dust from landing on the steps (6) during or after the installation work, accumulation of debris, etc. can be thoroughly removed and cleaned.

By the way, the material of the support plate (21) is wooden, iron, etc.
Although various materials can be used, elastic changes of the support plate (21) can be added by using an elastic body made of resin or the like.

In addition, in the above embodiment, the cleaning tool (20) uses the wool part (22) as the sliding material, but the cleaning tool (20) is not limited to this.
Other fur-like coverings, such as the fur of other animals or textiles with long fibers, may be used as long as they provide similar effects; [Effects of the Invention] As described above, according to the present invention, the cleaning tool includes a support plate and a fur-like covering having a raised portion on the sliding surface formed over the support plate. Since it is composed of , 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 and saving the cost and labor of additional cleaning. .
