Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wood cutting apparatus,

The present invention relates to a safer wood cutting apparatus, and more particularly, to a wood cutting apparatus using a disk-shaped cutter with improved stability.

The method of cutting the wood by rotating the disk-type saw blade is widely used because it is fast and convenient. However, accidents in which fingers or hands are cut on the rotary saw blade frequently occur. Accordingly, although a cutting apparatus that automates the entire cutting apparatus has been developed, there is a problem that an excessive cost is required and it is difficult to use in a small workplace.

A wood cutting apparatus is provided with a work plate on which a saw blade rotating by a motor is fixed and a rotating saw blade is protruded through a groove so that a worker rotates a saw blade passing through a cutting portion of the wood, Cutting apparatuses are widely used. Such a stationary cutting device is useful when the size of the wood is small or the length is short so that the operator can easily move the wood.

However, when the length of the wood is long, for example, 5 m or more, it is difficult to move the wood to the fixed saw blade, the wood is put on the workbench and the rotating saw blade is slid so as to reciprocate the workbench, It is convenient to use a cutter cutting device.

1 shows a conventional mobile cutting device 100 in a simplified manner. A rail 10 is provided under the movable cutting device and a disk-shaped saw blade 30 rotated by a motor (not shown) along the rail slides and reciprocates in a predetermined section. A groove 50 is formed in the upper work table 40 in parallel with the rail from one side to the other side, and a saw blade rotating on the work table 40 is reciprocated.

In order to prevent the worker from being injured by the rotating saw blade 30, the saw blade safety cover 60 is integrally fixed to the movable cutting device 100 so as to be spaced apart from the bottom of the work table by a predetermined distance, Is formed with a handle 70 for reciprocating the saw blade.

2, when a worker fixes the wood 200 on the upper work table 40 so as to traverse the groove 50 and pulls the handle 70 of the movable cutting device 100, the rotating disk- Moves along the groove 50 toward the worker, and cuts the wood 200.

For safe operation, the handle (70) must be pulled off with both hands while the wood (200) is fully fixed. To increase the work speed, pull the handle (70) A lot of accidents occur when the wood is caught or moved in front of the rotary saw blade.

Accordingly, there is a continuing need for a new method for increasing the safety of a mobile cutting device.

A problem to be solved by the present invention is to provide a new safe wood cutting apparatus.

In order to solve the above-mentioned problems, the safety-improved wood cutting apparatus according to the present invention includes:

A sliding rail (10) installed on the floor of the work table;

The movable cutting device 100 includes a saw blade turning motor 20 and a driving motor 20 for rotating the sliding rail 10 perpendicularly to the ground rotated by the motor 20 And a handle (70) fixed to the safety cover (60), the first safety cover (60) covering the upper portion of the circular saw blade, and the handle (70)

A work table 40 having a groove 50 parallel to the rail; And

A first inclined bar 81 fixed on one side of the safety cover 60 so as to be rotatable at a higher position than the safety cover 60 and extending obliquely to one side of the work table, and a second inclined bar 81 bent at the end of the first inclined bar, And a second inclined bar 82 which is inclined while extending to the other side of the work table and is raised by advancement of the first safety cover 60 and descends by the backward movement of the first safety cover 60, 2 Safety cover (80)

And a control unit.

The wood cutting device according to the present invention is provided with a new cutting device whose safety is improved by an additional safety device.

The safety-improved wood cutting apparatus according to the present invention prevents direct exposure to a rotating saw blade, that is, a rotary saw blade approaching a worker, thereby enabling safer working.

In particular, the second safety cover 80 covers the grooves through which the saw blades are reciprocated, thereby preventing the hands from being positioned in the grooves during the operation, thereby preventing the cutting blades from being damaged by the saw blades.

Hereinafter, the present invention will be described in more detail with reference to Examples. It should be noted that the following examples are not intended to limit the invention, and the following examples are intended to illustrate the invention.

As shown in Fig. 3, (a) is a side sectional view of the wood cutting apparatus of the present invention, and (b) is a plan view. A rail 10 on which a movable cutting device 100 can move is provided at the bottom of the work table 200. If the rail has a cross section of "DELTA ", the rail 11 is provided so as to be able to roll and move the concave groove in the central portion. Preferably, the rail 10 is a two row rail, and the four wheels 11 are mounted in two rows.

The movable cutting device 100 includes a saw blade rotating motor (not shown) on a frame 110 supported by a wheel 11, a disk-shaped saw blade 30 perpendicular to the paper rotating by the motor, The first safety cover 60 covering the upper portion of the disk-shaped saw blade and the handle 70 are coupled to each other. The safety cover 60 covers the top of the saw blade in a semicircular shape.

A groove 50 through which the saw blade 30 can pass is formed across the work table 40 from one end to the other end of the work table 40. The groove 50 is formed in parallel with the rail, So that the saw blade can move without being caught by the work table 40.

The second safety cover 80 is accurately positioned at the upper portion of the groove 50 of the work table 40, as shown in the plan view of FIG. 3B. The second safety cover 80 extends from one side of the work table 40 on which the saw blade enters to the other side of the work table 40 to cover the movement path of the saw blade 30. Accordingly, when the user holds the wood 200 by hand, the operator can avoid the second safety cover 80, which is the path of the saw blade, to fix the wood by hand.

The second safety cover 80 is pivotally coupled up and down to a support 83 standing vertically on the rear side of the rail 10, as shown in the side sectional view of Fig. A hinge may be used in which one side is coupled to the support 83 and the other side is coupled to the second safety cover 80 for pivotable engagement.

The second safety cover 80 includes a first inclined bar 81 extending from the support table 83 to one side of the work table 40 on which the saw blade enters and a second inclined bar 81 extending from the side of the work table 40 on which the saw blade enters, And a second inclined bar 82 extending to the other side of the work table 40. The first inclined bar 81 is made of one straight wood and the second inclined bar 82 is made of two straight woods connected to both ends of the first inclined bar 81 at the same angle. In this case, the operator can visually observe the saw blade through the gap formed between the second inclined bars 82.

The inclined bars are inclined toward the ground, and the inclination of the first inclined bar 81 is lower than the inclination angle of the second inclined bar 82.

The inclination of the first inclined bar 81 may be an angle of about 5 to 10 degrees with respect to the movable cutting device 100 and the incline of the second inclined bar 82 may be inclined by the inclination of the movable cutter 100, , It is formed in a shape similar to a slope of a straight line connecting the first safety cover and the other side of the workbench, and preferably has a range of about 30 +/- 10 DEG.

The second safety cover 80 operates as shown in FIG. When the movable cutting device 100 is at the end of the rail, the second safety cover 80 maintains the free end of the second tilting bar 82 supported by the work table. The upper end of the first safety cover 81 pushes up one side of the first inclined bar 81 of the second safety cover 80 when the movable cutting device 100 is placed in the groove into which the saw blade enters, , The wood 200 is placed on the worktable 40. When the movable cutting device 100 is moved toward the wood 200 in a state where the wood 200 is positioned, the upper end of the first safety cover 60 is moved to the second inclined bar 82 of the second safety cover 80, .

When the movable cutting device 100 is retracted after cutting the wood 200, the second safety cover 80 is lowered by gravity to block the movement path of the saw blade. The operator pulls the handle again to approach the movable cutting device 100 while holding the wood while avoiding the second safety cover 80. [
