Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a surface processing tool for an ALC (lightweight cellular concrete) panel used as, for example, an outer wall material of a building, and a surface processing apparatus using the same. More particularly, the present invention relates to a surface processing tool for forming a desired uneven pattern on the surface of an ALC panel and a surface processing apparatus using the surface processing tool.
[0002]
[Prior art]
The ALC panel is excellent in economic efficiency, light weight, fire resistance and heat resistance, and workability, and is widely used particularly as an outer wall material and partition material of a building. However, ALC panels generally use a manufacturing method in which the raw slurry is semi-cured in a mold, then removed and then cut into a panel shape with piano wire or the like. There is a problem that it is scarce. Therefore, in recent years, the demand for ALC panels having excellent design properties has increased, and various methods for patterning the panel surface have been proposed.
[0003]
Among these methods, examples of conventional methods for patterning the surface of an ALC panel after autoclaving include the following.
(1) As described in Patent Document 1 below, a method of cutting the surface of an autoclaved ALC panel with a rotating blade to give an uneven pattern.
(2) A method of forming an uneven surface by causing a projection material such as a small steel ball to collide with the panel surface using an emperor unit as described in Patent Document 2 below.
(3) A method of forming a peeled body by peeling off one side or both sides of a groove processed on the surface of an ALC panel using a peeling tool as described in Patent Document 3 below.
(4) A method of forming a large number of depressions by hitting the surface of an ALC panel with a needle or the like as described in Patent Document 4 below.
[0004]
However, the method (1) is a method usually used in the processing of ALC panels, but the design obtained is limited to a mechanically uniform one. The method (2) has problems such as troublesome operations of projecting and collecting small steel balls to be used and removing small steel balls remaining in the bubbles of the ALC panel. In the method (3), the panel groove needs to be processed in advance, and the peeling tool is inserted into the groove to peel off one side or both sides of the groove. The alignment is troublesome and the processing is limited to the periphery of the groove, making it difficult to process a large area. Furthermore, as shown in (4), an object that is struck with a needle or the like has a problem that the area processed by one impact is narrow, and it is difficult to increase the processing efficiency even if the number of needles or the like is increased. In addition, since the jig used in the above method is a single operation by itself, a complicated apparatus configuration (for example, an NC apparatus or the like) is required to obtain an arbitrary (similar to manual operation) design. Was necessary.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an ALC panel surface processing tool and a surface processing apparatus according to the present invention will be described in detail based on embodiments shown in the drawings.
[0011]
1A and 1B show an embodiment of a surface processing tool for an ALC panel according to the present invention. FIG. 1A is a front view and FIG. 1B is a cross-sectional view taken along the line bb in FIG. The surface processing tool 1 of the present embodiment is provided with a rotation drive shaft 3 integrally at the center of the outer surface of a pair of rotating disks 2 and 2 as rotating bodies provided facing each other, and the rotation A plurality of support shafts 4 in the circumferential direction, in the illustrated case, three support shafts 4 are attached between the discs 2 and 2, and a processing claw 6 as a processing member is attached to each support shaft 4 via an eccentric drum 5. It is.
[0012]
As the processing claw 6, in this embodiment, as shown in FIG. 2, a large number of round bars are used, and the processing claw 6 made of the round bar is implanted in the support substrate 7, and the support substrate 7 is attached to the missing circle 5b of the eccentric drum 5 so as to be detachable with a bolt 7a. The shape, number and arrangement of the processing claws 6 attached to the three eccentric drums 5 via the support substrate 7 are appropriate. In this embodiment, the shape, number and arrangement of the processing claws 6 are the same. The arrangement is almost the same, and only the arrangement positions are different as shown in FIGS.
[0013]
The eccentric drum 5 is formed with an attachment hole 5a for the support shaft 4 larger by about 20 to 50% than the outer diameter of the support shaft 4, and is eccentric with respect to the center position of the drum 5 having a substantially cylindrical shape. The eccentric drum 5 is swingably held with respect to the support shaft 4 by inserting the support shaft 4 through the mounting hole 5a.
[0014]
Further, between the eccentric drums 5 and 5 adjacent to each other in the circumferential direction of the rotating disk 2, a swinging bar 8 that regulates the swing range of each eccentric drum 5 and applies a scraping force to the eccentric drum 5 during processing. Each of the scraping bars 8 is formed in a sleeve shape in this embodiment, and is configured to be fitted and held on the peripheral surface of the support bar 9 attached between the rotating disks 2 and 2.
[0015]
The support shaft 4 and the support bar 9 are detachably attached to the rotating disk 2 by bolts or the like not shown in the drawing, whereby the eccentric drum 5 and the processing claw 6 can be replaced, or the scraping bar 8 It is configured so that the thickness of the can be easily changed.
[0016]
FIG. 4 shows an example of a surface processing apparatus using the surface processing tool 1, and in this example, the surface processing tool 1 is provided on the movable frame 10.
[0017]
The movable frame 10 is held by a support member (not shown) so as to be movable up and down, and is configured to be rotatable in a horizontal plane and movable in the horizontal direction. A pair of bearing members 11 and 11 are provided at the lower portion of the movable frame 1, and the surface processing tool 1 is rotatably supported by the bearing members 11 and 11 via the rotary drive shaft 3. .
[0018]
The rotary drive shaft 3 is provided with a driven pulley 12, and power is transmitted to the driven pulley 12 via a belt 13 from a drive pulley (not shown) that is rotationally driven by a drive source such as a motor (not shown). By doing so, the rotary drive shaft 3 and the rotary disks 2 and 2 are configured to be rotationally driven at a predetermined speed.
[0019]
When processing the surface of the ALC panel P by the surface processing apparatus configured as described above, the surface to be processed of the panel P is faced up as shown in FIG. The surface processing tool 1 is placed thereon. Then, from a driving pulley (not shown) that is rotated by a driving source such as a motor (not shown), the rotation driving shaft 3 and the rotating disk 2 are connected via the belt 13 and the driven pulley 12, for example, FIG. When the surface processing tool 1 is moved relative to the panel P in the direction of the arrow in FIG. 5A, for example, while the processing claw 6 is in contact with the panel surface while rotating in the direction of the arrow at a predetermined speed. Good.
[0020]
At that time, the surface processing tool 1 rotates in a state in which the processing claw 6 is directed outward in the radial direction as shown in FIG. 6A by centrifugal force in a free rotation state before contacting the panel surface, When the surface processing tool 1 is lowered in this state, the tip of the processing claw 6 on one of the eccentric drums 5 collides with the panel surface as shown in FIG. At that time, depending on the rotational speed of the rotating disk 2 and the relative movement speed of the surface processing tool 1 and the panel P, a plurality of hitting marks are formed on the panel surface such that the processing claw 6 strikes the panel surface a plurality of times. The
[0021]
When the rotating disk 2 continues to rotate, the tip of the processing claw 6 moves in a substantially tangential direction of the rotating disk 2 while gradually biting into the panel P as shown in FIGS. Directional scratch marks are formed. At that time, the processing claw 6 and the eccentric drum 5 rotate while gradually rotating backward in the rotational direction from the radial direction of the rotating disk 2 as shown in the figure by the resistance of the panel P, and at the same time, It moves slightly upward within the gap between the mounting hole 5a and the support shaft 4.
[0022]
Then, when the processing claw 6 and the eccentric drum 5 are further moved backward in the rotational direction, the eccentric drum 5 comes into contact with the scraping bar 8 located on the rear side in the rotational direction as shown in FIG. Further, the backward rotation of the rotating disc 2 is prevented, and at the same time, the scraping bar 8 acts to scrape the processing claw 6 forward and upward by the subsequent rotation of the rotating disk 2. As a result, as shown in FIG. 5B, a part of the panel ahead of the processing claw 6 is removed so as to be removed, and a peeling mark is formed on the panel surface.
[0023]
By repeating the above operation, a hitting mark due to the collision of the processing claw 6, a scratching mark due to the movement of the processing claw 6 in a substantially horizontal direction, and a peeling mark due to the scraping bar 8 are sequentially formed on the surface of the ALC panel. It is possible to obtain a novel surface texture not found in the field.
[0024]
The properties, formation range, and the like of the processing marks S such as the hitting marks, scratching marks, and peeling marks are appropriately adjusted by adjusting the rotation speed of the rotating disk 2 and the relative movement speed of the surface processing tool 1 and the panel P. The depth of the processing mark can be arbitrarily adjusted by changing the height of the movable frame. Furthermore, if the movable frame is moved up and down during processing, the above-mentioned processing trace can be given a wave shape, a stepped shape, or any other height difference.
[0025]
Further, the above-mentioned processing traces may be provided on a part or the entire surface of the panel P. For example, in the case of the configuration shown in FIG. 5, the surface processing tool 1 is moved twice in the panel longitudinal direction. By scanning, a processing mark can be formed on the entire surface of the panel P. Further, if the length dimension of the surface processing tool 1 is formed to be equal to or longer than the width of the panel P, a processing mark S can be formed on the entire surface of the panel P by one movement scanning.
[0026]
In the above-described embodiment, the processing claw 6 is formed by cutting the tip portion of a round bar material substantially at right angles to the axial direction, but the tip portion may be cut obliquely, and is not limited to a round bar shape, and has a polygonal cross section. The shape, the shape in which the tip portion is bent in a bowl shape, or a plate shape may be used, and the shape and arrangement configuration of the processing claws 6 are appropriate. For example, if it is pin-shaped things, such as a round bar or a square bar, a deep processing shape with a narrow width will be obtained, and if the space | interval of the processing nail | claw 6 is wide, it will become a deeper processing shape.
[0027]
In the surface processing apparatus of the above-described embodiment, the surface processing tool 1 is relatively moved in the longitudinal direction of the panel P to perform processing. However, the movable frame 10 of the surface processing apparatus can be rotated in a horizontal plane as described above. And may be processed by relatively moving in the width direction of the panel P. Alternatively, for example, as shown in FIG. it can. Furthermore, the rotating direction of the rotating disk 2 as a rotating body can be rotated in the direction opposite to that shown in FIGS. 5 to 7, and depending on the processing shape to be obtained, the orientation of the surface processing tool 1, the rotating direction, What is necessary is just to set rotation speed etc. suitably.
[0028]
Further, in the surface processing apparatus of the above embodiment, the surface processing tool 1 is arranged on the movable frame 10, but the surface processing tool 1 can be mounted on a hand drill D or the like, for example, as shown in FIG. In that case, if the rotational speed of the hand drill D, the relative movement speed with respect to the panel P, and the height position with respect to the panel P are appropriately adjusted, a desired processing trace can be formed in the same manner as in the processing apparatus.
[0029]
