Abstract

<P>PROBLEM TO BE SOLVED: To provide a brush roll which has excellent cleaning performance and performance to remove objects such as foreign matters. <P>SOLUTION: The brush roll 1 comprises a nearly rod-shaped or cylindrical shaft 2, and a brush part A4a and a brush part B4b spirally wound on the outer periphery of the shaft 2. The inclination angles of the brush part A4a and the brush part B4b are made symmetric with respect to a central symmetry axis 3 being set at a part in the longitudinal direction of the shaft 2 when the brush part A4a and the brush part B4b are wound, and the brush part A4a and the brush part B4b are parallel arranged. Thereby, the cleaning performance is improved by a plurality of brush parts A4a, B4b. Further, since the brush part A4a and the brush part B4b can be expanded in the longitudinal direction of the shaft 2 by enlarging the inclination angle during winding, objects such as foreign matters on a surface to be cleaned can be swept away to the outside together with a cleaning solution while effectively intercepting the cleaning solution by dam effect. Furthermore, the surface to be cleaned is prevented from being marked by the brush part A4a and the brush part B4b by enlarging the inclination angles of the brush part A4a and the brush part B4b. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a brush roll and a cleaning device that perform cleaning, cleaning, polishing, surface treatment, and the like on a steel plate, a non-ferrous metal plate, a resin plate, a glass plate, or a film-like resin composition.

  As a conventional brush roll of this kind, a brush is formed on the outer peripheral surface of a roll body by spirally wrapping a brush symmetrically with respect to the central axis of symmetry and rotating it on a blank material such as a steel plate. There is one that removes dust or the like adhering to the surface (for example, see Patent Document 1).

  FIG. 7 is a plan view of a conventional brush roll described in Patent Document 1, and FIG. 8 is a perspective view showing a state in which a blank material is washed with the brush roll.

  In FIG. 7, a conventional brush roll 40 includes a roll body 41 and a brush 42 that is wound around and fixed to the outer periphery of the roll body 41 in a spiral manner. The brushes 42 are provided symmetrically with respect to the symmetry axis 43 set at the center of the roll body 41 and spirally provided one by one from the symmetry axis 43 toward each end of the roll body 41. S is a starting end when the brush 42 is wound around the roll body 41.

  Next, the cleaning of the blank material by the brush roll 40 will be described with reference to FIG. 45 is a blank material that requires cleaning, such as a steel plate before processing, and the position of the brush roll 40 is set so that the tip of the brush 42 is in sliding contact with the surface of the blank material 45.

  Then, while feeding the blank 45 in the direction of the white arrow by the moving means (not shown), the driving means 46 causes the brush roll 40 to rotate counterclockwise as indicated by the solid line arrow and the peripheral speed of the tip of the brush 42 is blank. The cleaning liquid is rotated at a rotational speed that is higher than the moving speed of the material 45, and at the same time, the cleaning liquid is sprayed from the cleaning nozzle 47 toward the rotation inlet of the brush roll 40.

  By doing in this way, the objects 48 such as dust and gold dust adhering to the surface of the blank material 45 move together with the cleaning liquid from the substantially central portion in the longitudinal direction of the brush roll 40 toward the end portion and are removed. .

  However, in the configuration of the conventional brush roll 40, as shown in FIGS. 7 and 8, only one brush 42 is spirally arranged from the central axis 43 of the roll body 41 toward the left and right ends. Therefore, the inclination angle α of the brush 42 is large, so that the gap G between the adjacent brushes 42 is large, and there is a problem that the cleaning performance is poor.

  In order to solve this problem, a method of reducing the inclination angle α of the brush 42 and reducing the gap G between the adjacent brushes 42, that is, a method of winding the brush 42 around the roll body 41, is conceivable. The problem that the force by the brush 42 for moving the object 48 from the center to the left and right ends is reduced, and the object 48 remains on the surface of the blank material 45, which hinders the processing of the blank material 45. is there. Further, when the inclination angle α of the brush 42 is reduced and the movement direction of the blank material 45 and the rotation direction of the brush 42 become substantially the same direction, the locus of the brush 42 contacting the surface of the blank material 45 is a brush mark. There is also a problem that remains as.

  An object of the present invention is to solve the above-mentioned conventional problems, and to provide a brush roll and a cleaning device that do not leave a brush mark on the surface and are excellent in cleaning performance and removal performance of objects such as foreign matters. To do.

  In order to solve the conventional problems, a brush roll according to the present invention includes a substantially rod-shaped or cylindrical shaft and a brush portion spirally wound around the outer periphery of the shaft. Centering on the symmetry axis set in a part of the longitudinal direction, the inclination angle α at the time of winding is symmetric, and a plurality of them are provided in parallel on each of the left and right sides. In addition to improving the cleaning performance, compared to the case where only one brush part is provided on each of the left and right, the brush part can be expanded in the longitudinal direction of the shaft by increasing the inclination angle α of the brush part. An object such as a foreign substance on the surface to be cleaned such as a blank material can be washed out together with the cleaning liquid while effectively damming the cleaning liquid. Furthermore, the brush mark is less likely to be attached to the surface to be cleaned by increasing the inclination angle α of the brush portion.

  Moreover, the cleaning apparatus of the present invention includes a brush roll according to any one of claims 1 to 4, a driving unit that rotationally drives the brush roll, and a plurality of spraying liquids such as cleaning liquid on the brush roll. It has a nozzle, is excellent in cleaning performance, and has a brush mark not easily attached to the surface to be cleaned.

Compared to the case where only one brush part is provided, the brush part can be widened in the longitudinal direction of the shaft by increasing the inclination angle α of the brush part. An object such as a foreign substance on the surface to be cleaned such as can be washed out together with the cleaning liquid. Furthermore, since the inclination angle of the brush portion is increased, it becomes difficult to attach a brush mark to the surface to be cleaned.

  In the second invention, in particular, the axis of symmetry of the first invention is set at the approximate center in the longitudinal direction of the shaft, and the movement distance of the object that is scraped from the center toward the end by the left and right brushes. Therefore, the cleaning effect is not uneven.

  In the third aspect of the invention, in particular, the end portion on the symmetrical axis side of either the left or right brush portion of the first or second aspect and the end portion on the symmetrical axis side of the other brush portion are arranged in the longitudinal direction of the shaft. Since the object directly below the symmetry axis of the surface to be cleaned is also reliably removed, no cleaning or removal leakage occurs.

  In the fourth invention, in particular, the brush portion according to any one of the first to third inventions is configured by a belt-like body having a substantially U-shaped cross section and a brush bristle material sandwiched with the core wire by the belt-like body. Thus, the manufacture of the brush part and the attachment of the brush part to the shaft are facilitated, and the brush roll can be provided at low cost.
