It is arranged on the table on which the conveyor 1 is installed,

Starting at one side of the conveyor (1) '/' type upper and lower support plates (11, 12) spaced vertically spaced in the downward inclined direction

.

Guide 20

As shown in Figures 3 to 5,

Interposed on the upper and lower support plates 11 and 12 of the base 10 so as to be inclined downwardly away from the conveyor 1 at one side of the conveyor 1, two or more are provided.

In particular, an elastic spring S1 is interposed between one guide 20 and the upper support plate 11 of each of the guides 20, and the elastic spring S1 is connected to the lifting drive unit 50. It acts as a buffer for the slider 30 that rises by.

Slider 30

As shown in Figures 3 to 5,

It is coupled to the guides 20 to be sliding in the inclined direction along the guides 20,

First body (31),

Two or more corresponding guides 32 formed in the first body 31 in an inclined direction and coupled with the guides 20, and

The second body 33 mounted to the rear of the first body 31

.

The first body 31 has a coupling part 311 which is erected at its rear part and two or more horizontal rods 312 which are mounted up and down in a row so as to face the conveyor 1 side from the coupling part 311.

The second body 33 is mounted to each horizontal bar 312 of the first body 31.

At this time, one of the two or more horizontal rods 312, the horizontal bar 312 and the second body 33 is a spiral spring (S2) is interposed, the spiral spring (S2) is retracted toward the coupling portion 311 side It serves as a buffer for the second body 33.

Further, a rectangular disk 34 is provided on the second body 33 and a free rotating horizontal guide roller 35 is further provided on the disk 34, and the horizontal part is formed on the side of the second body 33. A free rotating vertical guide roller 36 is disposed to intersect the guide roller 35.

As shown in FIG. 7A, the disk 34 and the horizontal guide roller 35 are coupled to each other by bolts or the like penetrating them, and the disk 34 and the second body 33 also penetrate them. Are mutually coupled by means of bolts or the like.

And the vertical guide roller 36 is also coupled to the end of the bolt and the like fastened to the side of the second body 33, the horizontal guide roller 35 and the vertical guide roller 36, the ball is disposed on the outer peripheral surface It has a kind of bearing structure consisting of an annular cover surrounding the ball.

Therefore, the side and the bottom of the panel 2 being transported are supported by the horizontal guide roller 36 and the vertical guide roller 36, respectively.

The cutter 40

As shown in Figures 3 to 5,

As a kind of cutting blade mounted on the slider 30 so as to be laid down by 45 degrees by a bolt or the like on the side upper corner region adjacent to the conveyor 1, that is, the disk 34 of the slider 30. The end is made to have a U shape.

Thus, the cutter 40 scrapes the panel 2 being transported by the conveyor 1.

Lifting drive unit 50

As shown in Figures 3 to 6,

For lifting and lowering driving in the inclined direction with respect to the slider 30,

A cylinder 51 mounted on the lower support plate 12 of the base 10, and

A piston 52 embedded in the cylinder 51 and having an end portion connected to the lower portion of the first body 31 through the lower support plate 12.

.

As a result, the elevating drive unit 50 has a kind of pneumatic cylinder structure in which the piston 52 moves forward and backward by selective air supply of an air supply unit connected to both sides of the cylinder 51.

Accordingly, the slider 30 is raised in the inclined direction along the guides 20 by the piston 52 advancing, and the slider 30 is moved by the piston 52 by the piston 52 retreating. Descend along the slopes).

The scraping device according to the present invention further includes a forward and backward drive unit 60 in the horizontal direction with respect to the horizontal guide roller 35,

The forward and backward drive unit 60 is

As shown in [a] and [b] of FIG.

Long hole 61 penetrates up and down in the disk 34 of the slider 30 and has a left and right length,

Square member 62 is disposed in the long hole 61,

A spiral portion 63 formed to penetrate the right and left ends of the disk 34 so as to be connected to the long hole 61 in the longitudinal direction of the long hole 61;

Adjusting bolt 64 is finally fastened to the square member 62 after being fastened to the spiral portion (63)

.

At this time, the square member 62 is connected to the horizontal guide roller 35 by a bolt, so that the square member 62 is retracted in the long hole 61 during the forward or reverse rotation operation of the control boat 64. In operation, the horizontal guide roller 35 also moves forward and backward.

Eventually, by adjusting the contact distance between the panel 2 supported by the horizontal guide roller 35 and the cutter 40 closer to or farther from each other, the cutting depth of the corner region of the panel 2 is finally adjusted. It will be possible.

Looking at the operating state of the scraping device according to the invention made of the above configuration,

As shown in FIG. 4, the slider 30 is retracted in the inclined direction by the piston 52 of the lifting drive unit 50.

As shown in Fig. 5, the panel 2 being transported on the conveyor 1 is detected by a separate sensor that is approaching the scraping apparatus of the present invention, and the lifting driving unit is controlled by the controller by the sensing. 50 is activated.

Thus, as in the figure in the upper circular dashed line of FIG. 5, the side lower edge area of the panel 2 being transferred is scraped by the cutter 40.

As shown in FIG. 6, when the scraping process is completed, the slider 30 and the cutter 40 are returned to their original positions by the piston 52 of the elevating driving unit 50.

Therefore, the cutter 40 raised by the elevating driving unit 50 is rounded so that the edge area from one front lower end to the rear lower end of the panel 2 being transferred may be changed according to the blade shape of the cutter 40. Can be scraped.

In the above description of the present invention with reference to the accompanying drawings described with a specific shape and structure "scraping device for the edge rounding of the panel", but the present invention can be variously modified and changed by those skilled in the art, such modifications And modifications should be construed as falling within the protection scope of the present invention.
