DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning holder for supporting a tubular wall of a paint roller brush from the inside for dewatering using centrifugal force due to rotation. Used for dehydration.

[0002]

2. Description of the Related Art A paint roller brush has a form in which a flexible brush is planted on the outside of a water-resistant cardboard tube. This pipe is rotatably mounted on the pipe, impregnated with paint, and used while being rolled in a coating section. In recent years, water-based paint has been used, but the roller brush used for the application work has been washed with water after collecting a part of the paint that has adhered to the surface by brushing. At present, a large amount of paint and water remain.

An apparatus disclosed in Japanese Patent Application Laid-Open No. 6-321463 is known as a roller brush cleaning apparatus. This device is based on the premise that solvent-based paint is used. The rotating shaft of the motor fixed to the support that swings up and down is directed downward, and this is used to support the roller brush from inside. Fix the split round bar, insert the roller brush into this round bar, face the inside of the container, drive the motor in that state, remove the paint impregnated in the flocked part on the roller brush surface by centrifugal force It is made possible. However, in this apparatus, since the position of the rotating shaft for rotating the roller brush is fixed, it is convenient to collect the paint that has adhered first, but when cleaning the roller brush thereafter, it is convenient. Unless each roller brush is removed and washed and centrifuged and dewatered again, it cannot be used for paint of a different color, and the workability is extremely poor. Further, this apparatus is dedicated to dehydration, and a separate stirring device was required to stir the paint when applying the paint.

[0004]

[Technical object] The present invention provides a washing and holding device for supporting a cylindrical wall of a paint roller brush from the inside for dewatering using centrifugal force due to rotation, thereby enabling agitation of paint and dewatering of the roller brush. It is another object of the present invention to enable the roller brush to rotate by using a portable driving means or the like.

[0005]

[Technical Means] The first technical means for solving this technical problem is to provide (a) a connecting portion with a rotation shaft such as a motor at a base end portion of a shaft body, and (b) a forward portion thereof. Fixing both ends of a plurality of agitating filaments in a state where the central part is bulged outward, and (c) a roller for determining the outer diameter of an imaginary circle formed by gathering the outermost peripheral parts of the filaments. Make it slightly larger than the inner diameter of the brush,
(D) fixing the stirring propeller at the tip of the shaft body. The second technical means is to fix both ends of the band-shaped blade to the shaft in place of the filaments in the above means, and the third technical means is between the filaments in the first technical means. This is to position the band-shaped blade and to fix both ends of the blade to the shaft. Also, when using band-shaped blades,
Displace the positions of both ends to fix the band-shaped blade in the circumferential direction,
Further, the technical means is to incline the central portion of the band-shaped blade in the width direction.

Since the base end of the shaft is provided with a connecting portion with a time axis such as a motor, the shaft can be fixed to any driving means. Therefore, the shaft can be rotated in an arbitrary direction by being held by a portable motor, for example, a chuck of a drive unit of an electric drill. Since both ends of the plurality of stirring filaments are fixed to the shaft body with the central portion bent outward so as to be swollen, the stirring filaments are immersed in a container filled with paint. When the shaft rotates, the paint flows horizontally. Further, since the stirring propeller is fixed to the tip of the shaft, the paint can flow in the vertical direction with the rotation of the propeller.
Therefore, this holding tool exerts an extremely strong stirring action because the paint can be caused to flow simultaneously in the horizontal and vertical directions.

On the other hand, the roller brush has a form in which a flexible brush is implanted on the outside of a water-resistant cardboard tube. Since they collectively form a virtual circle and the outer diameter is slightly larger than the inner diameter of the roller brush, this holder can be inserted into the roller brush cylinder to support the roller brush, and in that state, The roller brush can be rotated by driving the shaft. Therefore, by spinning the roller brush to which the paint has adhered, the adhered paint can be squeezed and collected by centrifugal force, or the washed roller brush can be dehydrated.

When the both ends of the band-shaped blade are fixed to the shaft instead of the filament in the first technical means, the stirring force in the horizontal direction can be increased as compared with the filament. The outer diameter of an imaginary circle formed by gathering the outermost peripheral portions of the band-shaped blades fixed to the shaft body is such that the outer diameter of the belt-shaped blade is swollen outward at the center. Since it is slightly larger, the band-shaped blade can support the roller brush. In addition, when the band-shaped blade is located between the filaments in the first technical means and both ends of the blade are fixed to the shaft, the roller brush is supported by the filament, but by using the band-shaped blade together. The stirring power of the paint is further increased.
When using band-shaped blades, the positions of both ends where the band-shaped blades are fixed are displaced in the circumferential direction to give a twist to the blades, or the center portion of the band-shaped blades is inclined in the width direction, thereby causing friction with paint. By increasing the power, the stirring power can be increased accordingly.

The holder was subjected to a dehydration test using a roller brush having a cylindrical inner diameter of about 3.8 cm and a length of 23 cm (weight in a dry state: 75 g), which is a common size between Japan and the United States. The roller brush was immersed in water as it was to impregnate water into the brush, taken out and weighed at the stage where continuous flow of water was obtained, and the weight was 425 g. Attaching the holder to the chuck of the drive unit of a commercially available rechargeable form drill, inserting it into the cylindrical wall of the roller brush impregnated with water, supporting and operating the motor,
The roller brush rotated at approximately 2,300 rpm. About 10
After a few seconds, the motor was stopped, the roller brush was removed, and the weight was measured to be 100 g. Therefore, 25 g of water remains in the brush, and 325 g of water is dehydrated.

As a result of the agitation of the paint and the dehydration of the roller brush, the paint can be applied in a homogeneous state by sufficiently agitating the paint using the holder, and after the application, the roller brush is removed using the same holder. The advantage is that the paint that has been rotated can be collected and the paint can be reused, and the paint can be reused.In addition, when washing the roller brush, sufficient dehydration can be performed, so immediately apply a different color paint using the same roller brush. can do. Since the base end of the holder is provided with a connecting portion to the driving means, it can be rotated by the portable driving means, so that there is an advantage that the roller brush can be rotated at any position and at any angle. .

FIG. 1 is a side view of a holder 1, in which a connecting portion 2 for attaching a base end (right side in the drawing) of a metal shaft 1 to a chuck of a portable drill (not shown) is provided.
A screw is formed on the tip side from that position. A stirring propeller 3 is disposed at the tip, and donut-shaped plates 6, 6 for supporting the ends of the metal filaments 5 are provided in front of the connecting portion 2 and at the rear of the propeller 3. Have been placed. Linear 5
In the present embodiment, four are used, the intermediate portion is bent outward to have some elasticity in the radial direction, and the diameter of the imaginary circle 10 formed by the outermost periphery is formed by roller brushing Slightly larger than the inner diameter of the cylindrical wall. The number may be two or more, and may be appropriately selected depending on the viscosity and amount of the paint. In addition, a band-like blade 11 for stirring is arranged between the filaments 5 and 5. This strip-shaped blade has holes slightly larger than the diameter of the shaft body 1 at both ends 12 of the strip-shaped metal plate, and both short portions are inserted through the shaft body 1, and the middle part is the same as the linear shape 5. It is bent outward.

At the connecting portion 2 side of the shaft body 1, the end portion 1 of the band-shaped blade
2 and the plate 6 are fixed with nuts 7 and 7, and the propeller 3, the end portion 12 of the band-shaped blade and the plate 6 are fixed with the nuts 8 and 8 on the tip side, and the positions of the nuts 6 and 7 are adjusted. Thus, the degree of bending of the filament 5 and the band-shaped blade 11 can be adjusted.

The filament 5 functions to stir the paint and to hold the roller brush for cleaning from the inside. To support both ends of the filament 5 on the plates 6, 6,
A known support mechanism, such as welding the end of the wire 5 to the plate or forming an engaging recess around the plate and engaging a locking portion formed at the end of the wire with the engaging recess. Can be adopted. The strip-shaped blades 11 used are strip-shaped ones independently of each other. However, a single cross-shaped plate is formed, and holes for inserting the shaft 1 into the intersections and the outer ends are formed. When drilling and inserting the hole at the intersection into the leading end of the shaft and bending each blade to assemble the holes at the outer end and inserting it into the rear end of the shaft 1, Becomes easier. Note that the angle formed by the adjacent strip-shaped blades 11 does not necessarily need to be the same, and the stirring force can be changed by appropriately changing the angle.

The shaft 1 is formed with a screw at the tip end because of the use of the nuts 7 and 8, but the screw may be formed over the entire length of the shaft, and the propeller 3, the band-shaped blade 11
When the plate 6 and the plate 6 are integrally formed or other fixing means such as welding or fixing with an adhesive, it is not necessary to form screws. The shaft 1, the propeller 3, the band-shaped blade 11, and the plate 6 may be formed of a synthetic resin other than metal. In particular, when the band-shaped blades and the plate are formed of metal or synthetic resin having spring elasticity, it is convenient for holding the roller brush. In this embodiment, the line 5 is used.
Although the roller brush is held by the band-shaped blades 11, it is a matter of course that a configuration in which the roller brush is held only by the filament may be adopted. In this case, the band-shaped blades may be arranged inside the linear shape, and the number may be different from the linear shape.
