Abstract

PURPOSE:To avoid contact of a rotary member witch a surface to be cleaned and to prevent the damage and contamination of the surface by the member by moving the rotary member to be moved by a motor along a guide member together with a sweeping member and the motor. CONSTITUTION:Since a surface 1 to be cleaned is inclined to horizontal, a guide member 3a between the two guide members 3a and 3b as a metallic rod is loaded with the rotary member 8. Consequently, the rotary member 8 is moved along the guide member 3a. Meanwhile, the other member 3b acts as a guide for the rotary member 8 to accurately move along the guide member 3a and is used for the sweeping member 2 to apply a fixed pressing force on the surface 1. Since the guide 3a and rotary member 8 are driven by frictional contact, the members 8 and 3a are slid even if the self-traveling cleaner is stopped due to any external force, and the burning of a motor 4 by locking is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a self-propelled cleaning device that is used in various fields and that runs on its own while wiping in the cleaning direction. It can be used to wipe the glass surfaces inside machines such as copying machines.

[Conventional technology]

Conventionally, as an example of this type of cleaning device, there is a self-propelled cleaning device that rotates and wipes a cleaning surface. This cleaning device includes a wiping member for wiping a cleaning surface, and a rotating center of the wiping member connected by a rotating shaft of a motor. This cleaning device is moved in the direction of cleaning by manual or other human power.

In this case, when cleaning narrow or dangerous places where no one can enter, where the area to be cleaned is large and difficult to use human power, or when the cleaning equipment is large, it can be used as an alternative to human power for movement. A self-propelled cleaning device that uses power to move the cleaning device by itself is being considered.

The self-propelled cleaning device includes a wiping member that wipes the cleaning surface,
It consists of a motor that rotates the wiping member and a rotating member that moves in contact with the cleaning surface.

[Invention or problem to be solved]

However, the conventional self-propelled cleaning device that wipes cleaning surfaces such as floors has a wiping member that wipes the cleaning surface and a rotating member that moves in contact with the cleaning surface. In terms of running on the cleaning surface, if you want to clean the cleaning surface to a very high level, there is a problem that the cleaning surface may get dirty or scratched by the running of the rotating member.

Further, when the cleaning device is self-propelled, the running stability of the rotating member is important in terms of whether the cleaning device can accurately self-propel in the direction to be cleaned. However, this cleaning device has a wiping member in addition to the rotating member for traveling, and this wiping member exerts force on the cleaning surface in various directions, so the rotating member moves stably in the correct direction. That was difficult.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a self-propelled cleaning device that can move accurately in the direction to be cleaned without staining or damaging the cleaning surface.

[Invention or Means for Solving the Problem] For this purpose, the present invention integrally includes a wiping member for rotating and wiping the cleaning surface, a motor for rotating the wiping member, and a rotating member for traveling, and The self-propelled cleaning device is a self-propelled cleaning device in which the wiping member is self-propelled along a guide member provided in a direction to clean the cleaning surface while wiping the cleaning surface with the force of the motor, and the rotating member is It is provided apart from the cleaning surface, is linked to the rotation of the motor, and moves along the guide member together with the wiping member and the motor. This is a self-propelled cleaning device.

[Effect]

The wiping member is rotated by the rotation of the motor and wipes and cleans the cleaning surface.

Further, since the rotating member is linked to the rotation of the motor and moves along the guide member, the rotating member can accurately move by itself along the guide member due to the rotation of the motor.

Moreover, since the wiping member, the motor, and the rotating member are integrated, when the rotating member moves along the guide member, the wiping member and the motor also move in parallel with the guide member.

Further, since the rotating member is provided apart from the cleaning surface and obtains a moving force through contact with the guide member, the rotating member can move along the guide member without coming into contact with the cleaning surface. Therefore, the cleaning surface will not be damaged or soiled by the rotating member.

〔effect〕

As described above, in the present invention, the cleaning surface is not soiled or damaged by the rotating member for traveling, so that extremely good cleaning results can be achieved.

Further, since the traveling direction of the wiping member is guided by the guide member, it is possible to accurately wipe a predetermined cleaning range.

〔Example〕

A first embodiment of the self-propelled cleaning device of the present invention shows a self-propelled cleaning device for wiping the shielding glass of a copying machine.

As shown in FIGS. 1 and 2, the cleaning surface l is a shielding glass having a rectangular glass surface. The wiping member 2 is a cleaning pad, and is a circular pad having a diameter large enough to cover the rectangular short side of the cleaning surface 1. Guide member 3a
and 3b are two parallel metal rods, which are provided parallel to the long rectangular direction of the cleaning surface l and away from the cleaning surface. The motor 4 rotates the wiping member 2, and the tip of the rotating shaft of the motor 4 is press-fitted and connected to the rotational center of the wiping member 2. The small gear 5 is provided to penetrate the rotating shaft of the motor 4. The large gear 6 is provided to mesh with the small gear 5.

The shaft 7 is coupled to the large gear 6. Rotating member 8
is made of a disk-shaped elastic body, is provided at a position apart from the cleaning surface 1, and is connected to the shaft 7. Case 9 is
The motor 4 and the shaft 7 are connected to each other, and the case 9, the wiping member 2, the motor 4, and the rotating member 8 move together.

Here, when the motor 4 is rotated, the wiping member 2 is not rotated, but the rotating member 8 is rotated via the small gear 5, the large gear 6, and the shaft 7. A groove 8a is formed on the circumference of this rotating member 8.
The rotating member 8 is sandwiched between the guide members 3a and 3b via the groove 8a.

Further, the cleaning surface 1 is attached to a dividing wall 11, which is a part of the main body of the copying machine, by an attachment member IO.

Since the cleaning surface 1 is inclined with respect to the horizontal direction, the rotary member 8 applies a load to the guide member 3a of the guide members 3a and 3b, which are two metal rods. Therefore, the rotating member 8
moves along the guide member 3a. On the other hand, the guide member 3b on the other side has the role of guiding the rotating member 8 to move accurately along the guide member 3a, and the role of providing a constant pressing force to the wiping member 2 or the cleaning surface l. is fulfilled.

The guide member 3a and the rotating member 8 are driven by frictional contact, so even if the self-propelled cleaning device or some other external force causes the rotating member 8 and the guide member 3a to slip, the motor It is possible to prevent burnout due to the lock in step 4.

In the first embodiment, two metal rods are used as the guide member, but a single metal rod or the like may be used instead.

FIG. 3 shows an overall view of a copying machine using the first embodiment.

A typical copying machine is divided into an optical section 13 that reads and transmits information written on original paper 12, and a toner section 14 that prints onto paper for copying. The optical section 13 includes a light source 15 and a reflecting mirror 16, and the toner portion 14 is provided with a photosensitive drum 17, a developing device 18, and a paper feed section 19.
, a paper feeding section 2°, and a paper distribution section 21. These two rooms are completely separated by a dividing wall 11, with only the light signal passing through the shielding glass 1a having the cleaning surface 1. In the optical section 13, the light emitted from the light source 15 is projected onto the base paper 12, passes through each reflection mirror 16, passes through the shielding glass la, and reaches the photosensitive drum 17. Further, in the toner portion 14, a signal from the optical portion 13 reaches the photosensitive drum 17, and a powder developer (toner) is transferred onto the copying paper passing through the paper feeding portion 20, thereby performing copying. In the toner part 14 of the above-mentioned general copying machine, powder developer (toner), paper powder, dust, oil mist, etc. are accumulated, and after a long period of time, the cleaning surface 1 of the shielding glass 1a is covered. Powder developer (toner), etc. may adhere to it. Therefore, optical part 1
The light signal from 3 was attenuated, which had the effect of deteriorating the clarity of the copied image. Therefore, this shielding glass la
It is necessary to clean the cleaning surface 1 of the copying machine, but since the copying machine is a precision machine and has many parts, it is extremely difficult to disassemble the device and clean it. Therefore, the above-mentioned self-propelled cleaning device is provided on the shielding glass, which is particularly susceptible to adhesion of powder developer. With the above configuration, a shielding glass that is always clean can be obtained, and a clear copy image can be obtained.

On the other hand, the cleaning time of this self-propelled cleaning device is determined by the characteristics of the drive motor and the reduction ratio of the gear, and the cleaning interval is determined by detecting the number of copies, copying operation time, etc. Additionally, switching between forward and reverse movement of the self-propelled cleaning device can be done by providing position sensors such as a motor lock current detector, optical sensor, magnetic sensor, etc. at both ends of the shielding glass. .

Although the first embodiment of the self-propelled cleaning device of the present invention is used in copying machines and facsimile machines, it can also be used in many other fields.
