Moreover, a switch sensor is attached to the cleaner 1 to automatically stop the operation of an escalator 4 when a foreign matter or clothes enter the cleaner 1 so as to prevent the occurrence of an accident and a failure in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator belt cleaner, and more particularly, to cleaning a belt using a brush, and automatically stopping the operation of the escalator when foreign matter enters the cleaner. The present invention relates to a belt cleaner devised to improve safety and to remove static electricity.

[0002]

2. Description of the Related Art A conventional escalator belt cleaner has a structure in which felt or the like impregnated with a cleaning agent or an antibacterial agent is held by a holder, and the holder is attached to a return-side entrance of the belt to wipe off dirt.

[0003]

As described above, since the conventional belt cleaner employs a method of wiping the surface of the belt with a felt or the like, the surface of the felt becomes dirty.
In particular, hand oil tends to stay and become so-called sticky,
The cleaning function declines in a short time. Also, in the case of felt, if solid matter such as sand adheres, it is difficult to remove it from the surface thereof, which damages the surface of the belt and significantly shortens the life of the belt.

[0004] In a conventional belt cleaner,
Since there is no means to detect when foreign matter or clothing has entered the interior, the escalator will continue to operate as it is, increasing the load, or if the foreign matter is a person's foot or hand. , Shoelaces, etc. are very dangerous because they may cause an accident.

The present invention has been proposed in view of the above problems, and has as its object to provide an escalator belt cleaner which has a long-lasting function as a cleaner, does not damage the belt, and is provided with safety measures. To provide.

[0006]

The constitution of the escalator belt cleaner according to the present invention is as follows. 1. The elastic body is curved in a C-shape along the belt to form a holder, and a brush is built into the inner surface of the holder and attached to the return-side entrance of the belt so that the belt can be cleaned at all times. Escalator belt cleaner composed of.

[0007] 2. 2. The escalator belt cleaner according to claim 1, wherein a switch sensor is attached to the cleaner, and when the sensor is activated, the operation of the escalator is stopped or an alarm is output. 3. 3. The escalator belt cleaner according to the above 1 or 2, wherein the brush is made conductive to remove static electricity from the belt.

[0008]

The belt cleaner is mounted on the return side belt by opening the opening of the holder, and is held at a fixed point by the return side entrance wall. The tip of the brush is constantly in contact with the surface of the belt, which wipes off dirt.

When the brush is worn, the holder is opened and only the brush is replaced. The switch sensor is
When a foreign object enters the cleaner, it detects this and outputs a signal. When a signal from the switch sensor is input, the control circuit of the escalator outputs an operation stop signal or an alarm signal to stop the operation of the escalator, or outputs an alarm by voice or the like.

[0010]

FIG. 1 shows a belt cleaner according to the present invention. The cleaner 1 comprises a C-shaped holder 2 made of plastic and a brush 3 incorporated in the holder 2.

FIG. 2 shows a state where the cleaner 1 is disassembled, and FIGS. 2A and 2B show a state where the brush 3 is deployed. The brush 3 is bendable by attaching a flocked material 3-2 on a flexible sheet 3-1 with a gap. However, the flocked material 3-2 in the central part a is close to fit the flat surface of the central part of the belt, and the density of the bristles 3-3 is designed to be high. FIG.
(C) shows the holder 2 and the holder 2 of the embodiment.
Is made of plastic, but may be made of elastic metal.

FIG. 3 is an explanatory view showing a state in which the cleaner 1 according to the present invention is mounted on the escalator 4, and the cleaner 1 is mounted on the belt 5 as shown in FIG. FIG. 5 shows that a pressure-sensitive switch sensor 6 is attached to the entire entrance of the cleaner 1 so that when a foreign substance or the like enters the cleaner 1, a signal is output from the sensor 6 to stop the escalator 4 or to issue an alarm 7 Drives.

[0013] By changing the hair quality of the brush,
By increasing the cleaning effect or imparting conductivity, the belt may be configured to remove static electricity charged on the belt. Further, the brush 3 of the embodiment implants the hair into the implanted material 3-2, but the implanting means is not limited to the embodiment.

[0014]

The belt cleaner according to the present invention is constructed as described above and has the following effects. 1. Since the belt is cleaned with the brush, the effect of removing dirt does not decrease, and the belt can be used for a long period of time and is sanitary. 2. Since the brush fits well on the surface of the belt, cleaning unevenness does not occur.

3. There is no danger of sand damaging the surface of the belt, as any sand-like material will fall off the brush tips. 4. By simply opening the holder, you can replace the brush with a different hair type, or if the tip of the hair becomes worn, you can easily replace it with a new brush.

5. The switch sensor is attached to the cleaner, and when a foreign object or clothing enters the cleaner, the operation of the escalator is stopped or an alarm is output, so that accidents and breakdowns can be prevented beforehand and it is safe. 6. By imparting conductivity to the brush, static electricity can be removed, making it difficult for dust and the like to adhere,
Eliminates discomfort caused by static electricity.
