Description

[Detailed description of the invention] The present invention relates to a device for removing burrs from the edge of a decorative board to which a board is pasted. A tension roll 4 that tensions and urges one of the rolls 2 and 3 in a direction away from the other roll 2 to project the sander belt 1 inside the sander belt 1 in a direction perpendicular to the running direction of the sander belt 1. is disposed so as to be movable in a direction perpendicular to the running direction of the sander belt 1, and this tension roll 4 is pressed against the sander belt 1, and the sander is placed between the upper and lower rolls 2, 3 and the tension roll 4. This relates to a deburring device characterized in that deburring is performed with a belt 1.

An object of the present invention is to provide a deburring device that can adjust the extension dimension of the sander belt in accordance with the width dimension of the workpiece and can keep the amount of burr removed constant.

The present invention will be explained in detail below with reference to Examples. The sander belt 1 is formed of an endless belt of abrasive cloth, and is suspended between upper and lower drive rolls 2 and 3. The upper drive roll 2 is rotationally driven by a motor 5, and the lower drive roll 3 is driven downward by a tension spring 6.
is tension-biased. Reference numeral 4 denotes a pair of upper and lower tension rolls disposed within the sander belt 1, and both ends of the rolls are rotatably supported by a pair of rods 8, 8 which are slidably attached to support tubes 7, 7.
A compression spring 9 is attached to the outer periphery of the rod 8 to press and bias the tension roll 4. The total spring force of the compression springs 9 attached to each rod 8 is set to be smaller than the spring force of the tension spring 6.

Therefore, the burr 1 of the base plate 11 protrudes from the end of the decorative board 12 to which the plate 11 is attached to the base plate 10.
3, the decorative board 12 is conveyed (in direction A) while being driven and driven while the decorative board 12 is pressed by the press roll 14, and the sander belt 1 is brought into contact with the end of the decorative board 12. This is for removing burrs 13. Here, when the width of the decorative board 12 is small, the tension roll 4 is moved forward by the compression spring 9 and the sander belt 1 is extended forward, and the decorative board 12 and the sander belt 1 are moved forward as shown in FIG. Deburring can be carried out without leaving any uncut parts by maintaining contact with the decorative board 12. Also, if the width of the decorative board 12 is large, the sander belt 1 is pressed by the end of the decorative board 12, so that it resists the compression spring 9. By moving the tension roll 4 so as to retract it, deburring can be performed without excessively scraping. Here, since the spring strength of the tension spring 6 is made greater than the spring strength of the compression spring 9, there is no fear that the sander belt 1 will bend between the upper and lower tension rolls 4, 4 as shown in Fig. 3a. , 3rd
As shown in Figure b, deburring can be performed with the sander belt 1 stretched.

As described above, according to the present invention, an endless belt-shaped sander belt is suspended between upper and lower rotatably driven drive rolls, and one of the pair of drive rolls is pulled and biased in a direction away from the other roll, A tension roll that extends the sander belt in a direction perpendicular to the running direction of the sander belt is disposed inside the sander belt so as to be movable in a direction perpendicular to the run direction of the sander belt, and this tension roll is used as a sander belt. Since the sander belt is used to remove burrs between the upper and lower drive rolls and the tension roll, the amount of overhang of the sander belt between the upper and lower drive rolls can be adjusted using the tension roll. Even if the width of the decorative board differs, the contact pressure of the sander belt between the upper and lower drive rolls and the tension roll against the edge of the decorative board can be kept almost constant, thereby preventing burrs on the decorative board. It can be removed in a constant amount without leaving any unscraped residue or excessive scraping.
