.

Here, the curve slider 42 is capable of sliding along the guide groove 21,

The body 43 further includes a drive motor 432 mounted on an upper portion thereof, and the cutter 431 is mounted on a rotation shaft of the drive motor 432.

And the cutter 431 has a structure having a plurality of radial cutting blades based on the rotation axis of the drive motor 432.

The first drive unit 50

As shown in Figures 3 to 5,

The vertical slider 41 to move up and down along the vertical guide 31 and the curve slider 42 to perform the front and rear curve sliding operation along the guide groove 21,

Mounting unit 51 is disposed so as to be interposed on the front side of the conveyor (1) and the vertical slider (41), that is fixed to the table on which the conveyor (1) is installed,

A first cylinder 52 hinged to a lower end of the mounting portion 51, and

A first piston 53 embedded in the first cylinder 52 and having an end coupled to the vertical slider 41 by a hinge;

.

As a result, the first driving unit 50 has a pneumatic cylinder structure that controls the forward and backward operation of the first piston 53 by selective air supply to one side and the other side of the first cylinder 52.

The second drive unit 60

As shown in Figs. 4 and 5,

Link portion 61 extending downward from the bottom of the vertical slider 41 of the cutting unit 40,

A second cylinder 62 hinged to a lower end of the link part 61, and

A second piston 63 embedded in the second cylinder 62 and having an end coupled to a lower portion of the body 43 of the cutting unit 40.

.

As a result, the second driving unit 60 has a pneumatic cylinder structure that controls the forward and backward operation of the second piston 63 by selectively supplying air to one side and the other side of the second cylinder 62.

Looking at the operation state of the trimming device for edge rounding of the panel according to the present invention having the above configuration,

First, as shown in FIG. 1, the upper one front vertex of the square panel 2 is defined as 'A' and the lower vertex is 'B', and the rear one upper vertex of the square panel 2 is 'D' and the lower vertex is set. It is set as 'C'.

4 shows a trimming device in a stopped state in which all operations are stopped. The vertical slider 41 descends along the vertical guide 31 and the curve slider 42 moves the guide groove 21. As the cutting unit 40 is lowered along the front lower state, the cutting unit 40 is positioned at the lower side in the first half than the conveyor 1.

When the conveyor 1 is activated and thereby the square panel 2 is transported,

Although not shown in the figure, it detects that the panel 2 being transferred through the sensor (limit sensor, etc.) is approaching the trimming apparatus of the present invention, and activates the first driving unit 60.

As shown in FIG. 5, as the first piston 53 of the first driving unit 60 moves forward, the vertical slider 41 rises along the vertical guide 31, and at the same time, the curve slider ( 42 curves upward along the guide groove 21 and ascends.

At this time, as shown in [A] of FIGS. 6 and 7, trimming the 'A' portion of the panel 2 being transferred to the cutter 431 of the cutting unit 40 for the first time with the cutter 431 is rounded. Processing.

Then, the first piston 53 of the first drive unit 50 is retracted in accordance with the feeding speed of the panel 2, so that the vertical slider 41 descends along the vertical guide 31, and at the same time The curve slider 42 curves downward along the guide groove 21 to move forward and descends, and as shown in [b] and [d] of FIG. 7 according to the trajectory according to this operation, the cutting unit 40 The cutter 431 also moves while trimming so as to round the section connecting the 'A' and 'B' and the 'B' portion of the panel 2. As a result, the panel 2 is trimmed rounding the corner area between 'A' and 'B'.

As shown in FIG. 8, when the trimming processing of the corner regions connecting 'A' and 'B' of the panel 2 is completed, the cutter 431 of the cutting unit 40 is transferred to the lower side of the panel 2. Descend further into non-contact contact with As a result, when the cutter 431 of the cutting unit 40 is positioned on the lower side of the panel 2 being transferred, the cutter 431 is in contact with the panel 2 so that the second driving unit ( As the second piston 63 of 60 is further retracted, the cutting unit 40 is further lowered.

9 and 10, according to the operation of the second driving unit 60 immediately before the rear end of the panel 2 being transferred is out of the cutter 431 of the cutting unit 40. As the second piston 63 moves forward, the body 43 of the cutting unit 40 moves upward with respect to the hinge engaging portion with the vertical slider 41 so that the cutter 2 of the panel 2 is moved. Start trimming rounding 'C' part

As shown in [B] and [C] of FIG. 10, the second piston 63 is gradually advanced and the body 43 is further lifted and rotated, so that the 'cutter 2' of the panel 2 is moved. The section connecting 'C' and 'D' and 'D' are rounded and trimmed. As a result, the panel 2 is trimmed rounding the corner area between 'C' and 'D'.

As shown in FIG. 11, when the trimming processing for the panel 2 is completed, the second piston 63 of the second driving unit 60 and the first piston 53 of the first driving unit 50 retreat simultaneously. While the cutter 431 of the cutting unit 40 moves to the lower side of the conveyor 1 in the first half. That is, it switches to the processing ready state for the panel 2 currently conveyed.

Although not shown in the drawings, in the case where one or more trimming devices are installed to face each other, after the first trimming of the corner region of the panel 2 by the lower trimming device, the panel is trimmed by the upper trimming device. Secondary trimming (finishing) for the edge area of (2) may be possible.

Therefore, the trimming device for the edge rounding of the panel according to the present invention is the displacement of the cutting unit 40 by the first and second drive units (50, 60) of the panel (2) Its main feature is that trimming is possible for the rounding of the front and rear corners.

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