Therefore, due to the sharp shape of the insertion piece 512, the sealing member 530 can be easily opened during the movement, so that the movement of the dust collecting chamber 510 is facilitated. Further, since the insertion pieces 512 are naturally contacted with each other due to the elasticity of the sealing member 530, they seal the inside of the dust collecting duct 520 to prevent dust from leaking.

In addition, when strong suction is performed by the dust collector, the pressure in the dust collecting duct 520 is lowered, so that the sealing member 530 is more closely adhered to prevent the dust from leaking.

In the present invention, it is preferable that the width of the dust collecting chamber 510 is smaller than the width of the dust collecting duct 520. This is because the lower end of the dust collecting chamber 510 is inserted into the dust collecting duct 520.

The present invention has a structure that the width of the dust collecting chamber 510 can be greatly reduced as compared with the conventional one. This is because the first circular saw 416 and the second circular saw 417 are arranged in parallel to each other in parallel to the cutting path 120 and not in a structure in which the first circular saw 416 and the second circular saw 417 are arranged in parallel, The width of the chamber 510 can be made very small. The width of the first and second circular saws is 5 to 10 times larger than the thickness of the first and second circular saws.

At the same time, the width of the dust collecting duct (520) can be reduced along with the width of the dust collecting chamber (510), thereby greatly reducing the space occupied by the dust collecting equipment.

Also, it is preferable that a sloping outlet 520a is formed on the side surface of the dust-collecting duct 520 so that dust is discharged in a different direction.

When the inclined discharge port 520a is formed to have an angle of about 30 degrees to 45 degrees, the dust in the dust collecting duct 520 can be discharged most effectively.

In the present invention, a groove picking part 600 may be further provided on one side of the work table 100. 7 is a perspective view showing the structure of the grooved portion.

The grooving part 600 is not a function for simply cutting the plywood, but is a structure for performing a work of forming a pair of cutting lines in parallel with each other by a predetermined length of the plywood for spacing the grooves.

2, the groove picking part 600 may be provided at a lower side of the work table 100, more specifically, at a position facing the cut part 400 .

The groove picking unit 600 includes a length display unit 610 attached to an auxiliary frame provided laterally on the work table 100 and a bar-shaped moving unit mounted on the upper part of the auxiliary frame, A steering member 630 coupled to the steering mechanism 620 and capable of indicating a point of the length indicating means 610 and a pointing member 630 attached to the adjusting member 620, And a position sensor 640 that senses the position of the display unit 400.

The length display means 610 may be a tape measure or may be in the form of a scribed or printed indicia of length in the auxiliary frame.

Further, the indicating member 630 may be in the form of an arrow, and the adjusting member 620 may be a hand moving type.

The position sensor 640 may sense a specific position of the cutting unit 400 and may control the progress of the cutting unit 400.

That is, when the steering member 620 is fixed by moving the steering member 630 so as to point to the length display means 610 by a desired groove length, the position sensor 640 also moves and stops at a specific position.

In this state, when the cutter 400 is driven, the plywood is cut off when it is detected by the position sensor 640, and after the clamping unit 200 moves back the plywood by the width of the groove, ) Is advanced again and is detected at the position. Thus, a home picking operation with a predetermined width is completed.

Hereinafter, the operation of the present invention will be described in detail.

An operator places the plywood to be cut on the table 110 of the workbench 100.

The slider 220 is driven by the interlocking of the rotary shaft 240 and the rail pinion 250 by driving the lumber feeding motor 230 of the clamping unit 200. Then, And horizontally moves along the guide rail 210 to reach the plywood. The pressing cylinder 262 is driven so that the pressing member 263 of the clamper 260 presses the plywood and presses the plywood so that the slider 220 moves back while moving the plywood, When it is located on the path 120, it stops.

The fixed cylinder 320 of the fixing unit 300 is driven to lower the jig block 330 and press the plywood plate in a fixed state to complete cutting.

The cutting unit 410 of the cutting unit 400 is linearly moved to the opposite side of the plywood by the cutting drive motor 431, the feeding pinion 433 and the feeding rack 150 of the feeding unit 430, The first and second circular saws 416 and 417 of the cutting means 410 protrude from the cutting path 120 and are exposed when the elevating means 420 is elevated by the operation of the elevating cylinder 421 .

The first and second circular saws 416 and 417 cut the plywood sheet by moving the entire cutting means 410 along the cutting path 120 toward the plywood plate by driving the conveying means 430 in the opposite direction .

At this time, the first and second circular saws 416 and 417 are rotated by the first motor 412 and the second motor 413, respectively, while rotating in opposite directions so as to face inward toward each other, The saw 416 first forms a cutting groove in the plywood and the second circular saw 417 performs cutting successively.

At this time, the generated dust is collected in the dust collecting chamber 510 and collected into the dust collecting duct 520, and then flows into the dust collecting duct 520.

The dust-collecting duct 520 is connected to a dust collector, and the dust therein is sucked into the dust collector. Since the insertion piece 512 moves while opening the sealing member 530 while being inserted into the dust collecting duct 520, the insertion member 512 is easily moved and the sealing member 530 is elastically moved to the dust collecting duct 520 ), So that the dust inside is easily discharged to the dust collector.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, as well as the appended claims.
