The support portion 10 is configured to support the wood to be cut or machined to be fed into the cutting portion 30. [

The cutting portion 30 may be constituted by a device for cutting a hole in the wood or cutting it to a predetermined width. Therefore, the cutting portion 30 is provided with a drill bit for drilling a hole or a circular saw blade for cutting .

In addition, the cutting unit 30 may be constituted by an apparatus for processing wood by computer numerical control.

The wood processed by the cutting portion 30 may be a wood, plywood or MDF wood panel.

The cutting unit 30 is vertically adjustable in height so that the height of the cutting unit 30 can be controlled by the control unit 70.

Thus, it is possible to adjust the height of the cut portion 30 with respect to a wood panel of various thicknesses.

A suction member (90) for sucking sawdust generated from the wood to be cut is connected to the cut portion.

Thus, the sawdust generated during the processing of the wood can be sucked through the suction member 90 and discharged to a designated position.

A wood such as a plywood or an MDF panel is moved to the cut part 30 in a state of being abutted against a support 18 provided on one side of the support part 10 in a state where the wood part is mounted on the support part 10.

A control unit (70) for controlling the operation of the cutter (30) is installed at one side of the cutter (30).

The wood cut by the cutting portion 30 is transferred in a state of being supported by the transferring portion 50 and moved to a subsequent processing step.

The support portion 10 includes a front support portion 12 for supporting the wood before the cutting portion 30 is inserted and a cutting support portion 16 for supporting the wood under the cutting portion 30.

The front supporting part 12 and the cutting supporting part 16 are formed with an opening 14 for applying a positive pressure or a negative pressure to selectively apply a positive pressure or a negative pressure to the opening 14.

A positive pressure or a negative pressure is applied to the opening 14 through the suction pipe or the blowing pipe 60 in a state where the suction pipe or the blowing pipe 60 is interlocked with the opening 14. [

The positive pressure means that the pressure is applied upward toward the wood supported by the front support portion 12 and the negative pressure means that the pressure to pull down the wood supported by the cut support portion 16 .

The positive pressure does not mean a pressure enough to float the wood completely from the front support portion 12 but means a pressure enough to reduce the frictional force between the wood and the front support portion 12. [

That is, the positive pressure means a state of discharging air through the opening 14, and may be, for example, 20 pascals (Pa) to 50 pascals.

As the positive pressure is applied in the direction toward the wood supported by the front support part 12 as described above, the wood to be processed can be moved more smoothly from the front support part 12 to the cut part 30 side.

Thus, the force required for the operation of moving the wood from the support 18 to the side of the cutout 30 in the state where the wood rests against the support 18 can be remarkably reduced.

On the front surface of the front support part 12, a feed guide protrusion 15 is formed in a straight line in the direction toward the cut part 30.

The feed guide protrusion 15 is formed of synthetic resin material such as rubber or polyurethane, and the feed guide protrusion protrudes 0.1 to 0.2 mm from the front support surface.

The transfer guide protrusion 15 may be formed by inserting and fixing rubber or polyurethane synthetic resin into the groove in a state where the groove is formed in the support portion 10.

In the case of wood or plywood, fine irregularities are irregularly formed on the surface of the wood particles due to the characteristics of the wood particles even though they are processed precisely.

The minute concavities and convexities are brought into contact with the conveyance guide projection 15 so that the contact of the surface of the conveyance guide projection 15 with the concave and convex surface of the wood prevents the wood from flowing right and left on the front support portion 12 .

That is, the surface of the conveying guide projection 15 formed in a straight line from the surface of the front supporting portion 12 toward the cut portion 30 is brought into contact with the minute concavities and convexities of the wood to exert frictional force, It is played a role to help move it straight toward.

Thus, even when the wood is subjected to the force applied during the processing of the wood by the cutting portion 30, the wood in the state of being stood on the front supporting portion 12 to enter the cutting portion 30 is moved in the left-right direction (That is, both sides with respect to the direction from the front support portion 12 toward the cut portion 30), and can enter the cut portion 30 straightly.

On the other hand, a negative pressure is applied to the opening 14 formed in the cutting support portion 16 so that the wood is pulled downward toward the surface of the cutting support portion 16 somewhat.

The negative pressure means a state in which air is sucked through the opening 14, and may be, for example, 30 pascals (Pa) to 70 pascals.

As described above, since the negative pressure is applied in the direction of pulling the wood supported by the cutting support portion 16, it is possible to prevent the wood from flowing due to the force applied during the processing of the wood, thereby improving the precision of the processing.

A straight conveyance guide recess 17 is formed on the surface of the cutting support portion 16.

The conveying guide recess 17 may be formed at a depth of 2 mm to 3 mm.

The minute concavities and convexities of the wood or plywood are brought into contact with the edge portions of the conveyance guide recesses 17. By the contact between the corner portions 172 of the conveyance guide recesses 17 and the concave- It can be prevented from flowing rightward and leftward on the side wall 16.

That is, the edge of the conveying guide recess 17 formed in a straight line on the surface of the cutting support portion 16 is in contact with the minute concavities and convexities of the wood to be conveyed to act as a frictional force, .

The cutting unit 30 is provided with a position sensor (not shown) for detecting the presence or absence of the wood to be cut.

For example, an optical sensor may be used as the position sensing sensor, and a positive pressure may be applied to the front supporting part 12 by detecting whether or not wood is present on the cutting part through the position sensing sensor, (16).

Thus, when the wood to be cut is placed only on the front support portion 12, since the wood is not yet introduced into the lower portion of the cut portion 30, positive pressure is applied only to the front support portion 12, When the wood is present under the cutting portion 30, negative pressure is applied to the cutting support portion 16 to prevent the wood from being cut.

In the opening 14 formed in the front supporting part 12, a rolling ball 142 for rolling the wood may be disposed.

In the opening 14 of the front supporting part 12, the rolling ball 142 is supported by an elastic body 143 such as a spring and is disposed so as to protrude upward from the surface of the front supporting part 12 by 2 mm to 5 mm do.

At this time, the opening 14 is provided with a pressure discharge ring 146, and the rolling ball 142 can be disposed inside the pressure discharge ring 146.

9 and 10, a discharge opening 1462 is formed in the pressure discharge ring 146, and a discharge opening 1462 formed in a pressure discharge ring 146 installed in the front support portion 12, Is formed to have a cross section that widens toward the upper side on the side end face.

Thus, the discharge opening 1462 is formed to have a cross-sectional shape like a diffuser, and is configured to apply a high pressure toward the upward direction.

The diffuser is an element for converting the velocity to pressure. By forming the discharge opening 1462 formed in the pressure discharge ring 146 in a sectional shape like a diffuser as described above, the air supplied to the discharge opening 1462 So that the velocity component is converted into a pressure component and exerts higher pressure toward the upward direction.

In addition, a concave portion 1422 is formed on the outer circumferential surface of the rolling ball 142 so that air can be blown through the concave portion 1422.

A plurality of support portions 10 are provided in front of the cut portions 30, and a sliding support member 20 is disposed between the support portions.

The sliding support member 20 may be formed of layers having three different characteristics. A panel contact layer 22 is formed on the sliding support member 20 to increase frictional force with the wood, A sliding layer 26 for reducing the frictional force with the edge 13 of the front supporting part 12 is formed on the lower part of the front supporting part 12. [

The panel contact layer 22 may be formed of, for example, a soft silicone or urethane layer in the state where fine irregularities are formed on the surface.

Thus, it is configured to prevent the damage of the wood surface due to the contact between the panel contact layer 22 and the wood, while increasing the contact frictional force with the wood contacting the panel contact layer 22.

The sliding layer 26 may be formed of, for example, a hard synthetic resin such as stainless steel or polypropylene having a smooth surface.

Thus, the sliding layer 26 can be smoothly slid and moved in a state of being in contact with the edge 13 of the front support portion.

Thus, the sliding support member 20 can be selectively moved between the front support portions 12 according to the size of the wood to be cut, and can be smoothly moved toward the cutting portion 30 in a state in which the wood is supported.

 8, a rolling ball 132 may be provided on the edge portion 13 of the front support portion or the sliding support member 20 may be provided on the edge portion 13 of the front support portion, as shown in FIG. 8, to smoothly move the sliding support member 20 toward the cut- The sliding layer 26 may be replaced by a sliding roller.

The wood cut through the cut portion 30 is transferred to the transfer portion 50 side.

The conveying unit includes a support frame 52 and a conveying roller 56 installed on the supporting frame 52. The conveying roller 56 is rotated in contact with the wood to move the wood.

The conveying roller 56 is formed in a cylindrical shape, and the surface of the conveying roller 56 is substantially the same as the support frame 52, but is installed at a very high height.

On the surface of the conveying roller 56, a conveying guide recess 562 is formed along the circumferential direction.

Thus, the corner of the conveying guide recess 562 is brought into contact with the surface of the wood, thereby preventing the wood from flowing in the lateral direction.

In addition, an opening 522 for applying a negative pressure is formed in the support frame 52, and a negative pressure is applied through the opening 522.

The negative pressure is weaker than the negative pressure acting on the cutting support 16, and may be, for example, 10 pascals (Pa) to 20 pascals.

In the process of transferring the wood through which the cutting is completed through the transferring unit 50, the negative pressure can be applied and stably moved as described above, so that the cut wood can be fed straight in a state in which the left and right flows of the cut wood are prevented, By preventing the flow of the wooden part being cut, it is possible to improve the precision of cutting.
