The idle roller 70 is equipped with a rotary encoder 75. The reason why the dimension of the idle roller 70 is slightly smaller than that of the downwardly advancing roller is that the advancing roller compensates that the diameter shrinks slightly due to elasticity when the panel is transported.

The rotary encoder 75 is not directly installed on the downwardly moving roller because the foreign material generated while the panel is cut is attached to the downwardly moving roller, so that an error in measurement may occur.

Rotating the advancing roller rotating lever 3 shown in FIG. 1 causes the rotary encoder 75 to display the feed amount, thereby accurately aligning the transverse cutting points of the panel.

Hereinafter, the operation and effects of the panel cutting device according to the preferred embodiment of the present invention will be described in detail.

First, the longitudinal cutting of the panel cutting device will be described.

When the panel placed on the support stand 2 is inserted into the panel entry gap of the main body 1, the entry rollers 10 of the main body 1 are driven so that the entry rollers 10 bite the panel and rotate the panel. Enter inside of. The panel which has passed between the entry rollers 10 advances through the wedge force generating roller 12 located in front of the entry rollers 10 and passes through the first cutter blade 100 of the first cutter holder 20. It is cut by the first cutter 100. The panel passes through the advance rollers 11 while advancing by the drive of the entry roller 10.

Cutting of the panel by the first cutter 100 is made while the wedge effect to be described later occurs.

11 is a view showing a concept of cutting while generating a wedge force by the first cutting blade of the panel cutting device according to an embodiment of the present invention. As shown in FIG. 11, the first cutter blade 100 mounted on the first cutter holder 20 is inclined to face the rear downward direction at the same time. Therefore, the panel to be cut is subjected to downward force by the first cutter blade 100, and sag occurs downward.

However, since the wedge force generating roller 12 disposed below the first cutter blade 100 supports the panel from below, the downward deflection of the panel does not occur. As a result, a wedge effect occurs while the panel enters between the first cutter blade 100 and the wedge force generating roller 12, and the panel receives wedge force. As a result, since the deflection does not occur, the cutting depth of the panel by the first cutter blade 100 is kept constant, and at the same time, the first cutting blade applies a stronger cutting force to the panel by the wedge effect, thereby entering the roller 10. The panel can be reliably cut while reducing the driving force by.

Next, the lateral cutting of the panel cutting device will be described.

In order to manufacture a large sized duct, the width of the panel must be large, and if the width of the panel is larger than the width of the board entry gap of the panel cutting device, the panel is placed in the transverse direction because the panel cannot be inserted in the longitudinal direction. And insert it. Here, the longitudinal direction refers to the longitudinal direction when the longitudinal length of the panel is longer than the horizontal length of the panel, and the transverse direction means the horizontal direction of the panel.

In the lateral cutting, the first cutter holder 20 on which the first cutter blade 100 is mounted is removed from the panel cutting device.

The rotary encoder 75 which displays the conveying distance by the advance roller 11 when the panel is squeezed in the transverse direction and pushes the panel through the entry roller 10 to pass through the entry roller 10. By rotating the advance roller 11 through the conveying distance display of the panel to transport the panel so that the point to be cut on the cutting line of the second cutter (200). Rotation of the advance roller 11 may be a motor or may be rotated through a manual tool.

The panel is cut in the transverse direction while the transfer part 40 moves forward while the cutting point of the panel coincides with the cutting line of the second cutter blade 200.

As shown in FIG. 9, since the transfer part 40 is waiting at the right end of the rail 15 before starting to cut the panel, the pressing piece 54 is formed by the striking protrusion 7 on the right side of the rail 15. The pressing piece 54 is moved in the direction from which the cam groove 55 of the elevating plate 42 escapes the cam protrusion 43 of the elevating plate 42, and the elevating plate 42 is in the state of being lowered downward.

In this state, when the transfer unit 40 proceeds to the left side of the rail 15, the second cutter blade 200 of the second cutter holder 60 mounted under the lifting plate 42 cuts the panel. When the cutting of the panel is finished and the conveying part 40 reaches the left end of the rail 15, the end of the pressing piece 54 of the conveying part 40 hits the striking projection 7 on the left side of the rail 15. 54) moves to the right. When the pressing piece 54 moves to the right, the cam protrusion 43 of the elevating plate 42 enters the cam groove 55 of the pressing piece 54, and the elevating plate 42 is elastically supported upward, so the cam groove is Ascend by a height of 55. The second cutter 200 fixed to the lifting plate 42 also rises together.

In the state where the second cutter 200 is raised, the transfer part 40 returns to the original position for the next cutting. The reason why the conveying part 40 raises the second cutter 200 at the time of return is to prevent the second cutter 200 from being damaged while the part of the panel is cut.

In the state where the second cutter 200 is returned to its original position, the panel is transported by rotating the advance roller 11 again so that the next cutting point of the panel is positioned on the cutting line of the second cutter 200, Repeat the process.

The cutter holder mounting portion 30 of the panel cutting device according to the present invention can selectively mount the cutter holder on the straight path between the one side support portion 31 and the other side support portion 37 without being limited in number and position. It is convenient to have.

In addition, since the inclined surface is formed on the seating protrusion 23 of the first cutter holder 20 and the cutting direction line 24 is displayed to the edge of the inclined surface, the ruler 38 and the cutting direction line 24 of the other side support portion 37 are mutually different. By contacting the first cutter holder 20 to the exact dimensions can be ensured the precise cutting position.

The panel cutting device according to the present invention can perform both vertical cutting and horizontal cutting by one device, thereby improving work efficiency.

The panel cutting device of the present invention adopts a configuration in which the transfer part 40 performing the transverse cutting is manually moved, but also automatically operates the transfer part 40 using a motor or the like, so that the transverse cutting is also completely automated. It is possible.

In the panel cutting device of the present invention, the term 'cutting' is not limited to cutting the object completely and is intended to include all cutting operations using a cutter blade such as forming a groove or forming a cutout.
