Hereinafter, a preferred embodiment of a sheet cutting machine according to the present invention will be described in detail with reference to the accompanying drawings (the same components as the conventional will be described using the same reference numerals).

Figure 2 is a perspective view showing a feature of the plate cutting machine according to the present invention, Figure 3 is a plan view showing a feature of the plate cutting machine according to the present invention, Figure 4 is a cross-sectional view taken line IV-IV of FIG.

First, before explaining the features of the plate cutting machine according to the present invention, a brief look at the plate cutting machine.

The plate cutting machine has a frame 10 as shown in FIG. 2, and a table 20 is installed on an upper surface of the frame 10. The table 20 supports and supports the plate material P to be cut.

And the sheet cutting machine, the drive motor 40 for rotating the first and second rotary saw blades (30, 32) and the first and second rotary saw blades (30, 32) installed to protrude to the upper surface of the table (20). And, the table 20 is provided with an early stage 50 is installed so as to move left and right.

The 1st and 2nd rotary saw blades 30 and 32 cut | disconnect plate material P supported by the table 20. As shown in FIG. The first and second rotary saw blades (30, 32), the height can be adjusted by the height adjustment knobs (30a, 32a) of the lower. Therefore, only one of the two can be used to protrude selectively.

The early stage 50 is provided with the reference surface 52 which can support one side of the board | plate material P, and can cut the board | plate material P to a set dimension with respect to the reference surface 52. As shown in FIG. Here, the reference plane 52 is parallel to the first and second rotary saw blades 30 and 32, as well as the first and second rotary saw blades 30 and 32 as the early stage 50 moves left and right. And distance are adjusted.

Next, look at the features of the plate cutting machine according to the present invention with reference to FIGS.

First, the plate cutting machine of the present invention is provided with a cutting detecting means 60 for detecting whether the cutting of the plate (P) is completed.

The cutting detection means 60 includes an optical sensor 62 provided at the rear portion of the rotary saw blades 30 and 32.

The optical sensor 62 detects this when the tip portion P1 of the plate material P cut by the rotary saw blades 30 and 32 enters the sensing range, and outputs a “cut signal”. And when the board | substrate P which entered was cut | disconnected completely and the rear end part P2 deviates from the sensing range, a "cut signal" is erased.

Therefore, it is detected whether the plate (P) is completely cut by the rotary saw blade (30, 32).

On the other hand, the cutting detection means 60 includes a control part 70. The control unit 70 has a built-in microprocessor. When the "cutting signal" applied from the optical sensor 62 is erased, the controller 70 determines that the plate P is completely cut and moved to the rear portion of the table 20. Outputs a "control signal".

2 to 4 again, the sheet cutting machine of the present invention includes an actuator 80 driven by the " control signal "

The actuator 80 is operated while being turned on when a "control signal" is applied from the controller 70. In particular, it is operated to press upwardly the protrusion pin 90 to be described later.

Here, the actuator 80 is composed of a solenoid or a pneumatic cylinder, the solenoid or pneumatic cylinder configured in this way operates in the direction of extension when a "control signal" is applied from the control unit 70.

Again, referring to Figures 2 to 4, the plate cutting machine of the present invention is provided with a protruding pin 90 is installed on the table 20, so as to press the upper surface of the cut plate (P) to the top. .

The protruding pin 90 is provided to move up and down between the lowered position ("X") inside the table 20 and the protruding position ("Y") above the table 20.

The protruding pin 90 is pressed by an actuating actuator 80, and the pressed protruding pin 90 is protruded from the lowered position ("X") inside the table 20 ("Y"). Protruding with a), and the protruding pin 90 protruded in such a way, a portion of the plate (P) cut is lifted to a certain height from the upper surface of the table 20.

Therefore, the plate P, which has been cut, is brought into a position that is easy for the worker to grip. As a result, the worker can lift and carry the board | substrate P which cutting was completed easily.

In addition, since the cutting is completed to the plate (P) at a certain height, the operator can easily grasp the plate (P) without having to approach the rotary saw blade (30, 32). As a result, the contact with the rotary saw blades 30 and 32 is prevented, thus reducing the safety accident due to the contact with the rotary saw blades 30 and 32.

On the other hand, when the operator lifts the plate (P) is completed cutting, after a few seconds, the actuator 80 is contracted, and as the actuator 80 is contracted, the protruding pin 90 is returned to the lowered position ("X") again do.

Again, referring to FIGS. 2 to 4, the sheet cutting machine of the present invention includes a timer for adjusting a time interval from the time of erasing the "cut signal" of the optical sensor 62 to the time of outputting the "control signal" of the controller 70. Equipped with 100.

When the "cut signal" of the optical sensor 62 is erased, the timer 100 counts the time so that the "control signal" of the controller 70 can be output after a preset time elapses. Therefore, the time interval from the time of erasing the "cut signal" of the optical sensor 62 to the time of outputting the "control signal" of the controller 70 is adjusted.

Here, the time interval set in the timer 100 can be adjusted as needed, the adjustment of this time interval is controlled through the time interval adjusting unit 102. The time interval adjusting unit 102 is preferably provided at the front of the table 20.

The timer 100 adjusts the time interval from the time of erasing the "cut signal" of the optical sensor 62 to the time of outputting the "control signal" of the controller 70, and thus protrudes from the time when the cutting of the plate P is completed. The time interval at which the pin 90 lifts the plate P upwards may be adjusted.

And since the time interval between the point of lifting the plate (P) from the time when the cutting of the plate (P) can be adjusted, it is possible to adjust the time of lifting the plate (P) at will according to the cutting speed of the plate (P). .

In the above described a preferred embodiment of the present invention by way of example, the scope of the present invention is not limited only to this specific embodiment, it can be changed appropriately within the scope described in the utility model registration claims.
