Abstract

PURPOSE:To eliminate the need for structural countermeasure for preventing moisture in a driving part, to prevent generation of rust, to prolong the service life of the driving part and to miniaturize a washing chamber by providing a partition for preventing liquid leakage in an operating transfer shaft between the supporting part of a brush in the washing chamber and a driving mechanism part in the outside of the washing, chamber in order to protect the driving mechanism part from splashing water. CONSTITUTION:A partition part is provided in an operating transfer shaft 9 between a brush supporting part 10 for water washing in a washing chamber 1 and an X, Y, Z-driving part 2 provided outside the washing chamber 1. The partition part has a structure for preventing liquid leakage which is freely moved in the X, Y and Z directions. In other words, sealing of X-movement is constituted of a right and left enfolding type plate connection member 6. Sealing of Y-movement is constituted of a back and forth folding type billows member 5. Sealing of Z-movement is constituted of an upward folding cylindrical bellows member 4. Thereby the transfer shaft 9 for transferring operation from the driving part 2 provided outside the washing chamber 1 is easily moved in the X, Y and Z directions. Operating power is accurately transferred to the brush supporting part 10 for water washing.

Description

Detailed Description of the Invention

[0001]

[Industrial application] In high pressure spray cleaning and brush cleaning adopted for precision cleaning of machined parts, etc., it relates to waterproofing measures for various drive members in the cleaning chamber.

[0002]

2. Description of the Related Art In a high pressure spray cleaning device and a brush cleaning device used for precision cleaning of machined parts,
As a conventional cleaning device structure, a drive unit in the cleaning chamber, or
In order to install a robot, a waterproof sliding structure is used or waterproof measures such as cleaning inside the enclosure are taken. FIG. 2 shows a brush cleaning device employing a conventional robot.

As shown in the figure, a robot 2 supporting a cleaning member 15 is installed in the center of a cleaning chamber 1, and a rotating brush 12 corresponding to the cleaning member is arranged around the water injection nozzle 11 and around the brush 12. A partition cover 22 for preventing water from scattering is installed around the.

The cleaning in the brush type cleaning device employing the robot as described above is shown in FIG.
The cleaning member 15 is grabbed by the robot 2 from 0, and depending on the cleaning parts 16, 17, 18, 19 of the cleaning member 15,
First, the cleaning of the entire surface of the cleaning member is completed while sequentially cleaning the cleaning parts 16 to 19 with the brush 12.

However, in a cleaning device in which the drive unit is installed in the cleaning chamber as described above, the waterproofness of the drive unit also affects the life of the cleaning device. Therefore, the ideal target is to isolate the drive unit from the influence of water. Although it is desired to do so, it has not been implemented because of structural difficulties.

[0006]

The complicated brush operating part for cleaning the entire surface of the cleaning member creates a water splashing atmosphere, but when the drive part for transmitting the operation of the operating part is installed outside the cleaning room, it is waterproof. The challenge is how to achieve a cleaning device structure that allows for accurate and accurate transmission.

[0007]

As shown in FIG. 1, X, Y, Z, which is an outside of the cleaning chamber, and X, Y, Z, which are outside the cleaning chamber, and X is a motion transmission shaft between the movable drive mechanism unit. By incorporating a partition of a liquid leakage prevention structure that is movable in the Y, Z, and directions, cleaning is performed by transmitting operation drive from outside the cleaning chamber to the cleaning chamber.

[0008]

As shown in FIG. 1, the washing brush support 2 in the washing chamber 1
And the X, Y, Z, which is outside the cleaning room, and the movable transmission mechanism section are provided with a partition of a liquid leakage prevention structure that is movable in the X, Y, Z, and directions, that is, a sealed X movement. Is a flat plate connecting member that can be rolled in to the left and right, a Y-movable seal is a folding bellows member to the left and right, and a Z-moving seal is a cylindrical bellows member that is folded upward. The transmission shaft for transmitting the motion from the outdoor drive unit is easily moved in the X, Y, Z directions, and an accurate motion force is transmitted to the washing brush support unit.

[0009]

EXAMPLES In a brush water washing type cleaning device structure, a brush operating drive unit was installed outside the cleaning chamber to develop a cleaning device in which splashed water was not applied to the drive mechanism unit. , Y, Z, a movable cleaning unit that employs a flexible partition structure that can be moved is a brush washing type cleaning device outside the cleaning chamber.

As shown in the figure, the transmission shaft 9 formed between the X, Y and Z outside the cleaning chamber, the movement driving unit 2 and the brush supporting unit 10 inside the cleaning chamber 1 constitutes the ceiling of the cleaning chamber 1. The ceiling part is a partition part of a liquid leakage prevention structure that is movable in X, Y, and Z directions, that is, the X movement is sealed by a retractable flat plate connecting member 6 by a weight through a pulley 7 on the left and right.
By using the bellows member 5 that can be folded to the left and right as the Y movement, and using the cylindrical bellows member 4 that can be folded upward as the Z movement, the operation from the drive unit 2 outside the cleaning chamber can be performed. The transmission shaft 9 for transmission easily moves in the X, Y, and Z directions, and an accurate operating force is transmitted to the washing brush support portion.

The X-moving hermetically sealed portion may be a bellows member such as Y, Z, and the like, but since the length becomes long, it is necessary to consider sagging due to its own weight.

The cleaning chamber 1 also includes a set table 20 for fixing cleaning members, washing brushes 12 to 14, a brush storage unit 21, and a brush support unit 10 to which a brush can be automatically attached and detached.

According to the cleaning method of the brush using the cleaning device as described above, the cleaning member 15 fixed to the set table 20 is, according to each cleaning portion, first the inner surface 1 of the cleaning portion.
Rotate the set table with respect to 6, and the inner and outer surface brush 1
2 rotation and cleaning with the water injection nozzle 11 are carried out. Next, the outer surface 17 and the bottom surface 18 are moved so that the brush comes into contact with the outer surface and the bottom surface, and the brush support portion 10 is moved along the arc motion by the XY movement. Cleaning by rotation is performed.

Further, with respect to the cleaning portion lateral hole 19, the brush supporting portion 10 is moved to the brush storage portion 21 so that the lateral hole surface brush 14 is automatically supported and fixed, and they are previously positioned by rotating the set table 20. The brush portion 14 is rotated by inserting the brush portion 14 into the side hole portion 19 of the cleaning portion, which is moved by Y movement, to perform cleaning.

A major effect of the structure of the brush washing type cleaning apparatus of the present invention is the effect of the waterproof surface due to the XYZ drive source being installed outside the cleaning chamber.

[0016]

EFFECTS OF THE INVENTION Since the drive unit is not affected by moisture outside the washing room, (1) it is not necessary to take structural measures to prevent moisture.

(2) No rust is generated because it is not affected by moisture.

(3) The drive unit has a long life due to a good environment outside the washing room.

(4) The washing chamber, which tends to be particularly large, can be made compact because the drive unit is outside.
