The die cutting device using a plate mold and a pressure roller according to the present invention is a device for cutting a sheet or roll-shaped material (3) in a certain pattern. Sheet-shaped materials are supplied individually, and roll-shaped materials are supplied continuously unwound.

In some cases, printing work rather than cutting may be performed, which is possible by replacing the plate mold 7 with a printing plate capable of silkscreen printing. In other words, the configuration for performing a printing operation instead of cutting is a technical concept within the scope of equivalents to the present invention.

The table (1) is installed at a certain height from the ground through a frame. A plate mold (7) is installed on the table (1) so that it can be lifted horizontally.

A blade (5) is installed on the upper surface of the plate mold (7). The material 3 is cut according to the shape of this blade. This type of mold is usually called ‘Domusong’ and is called a wooden mold. The plate mold (7) is fixedly installed on the table (1) with the blade (5) facing upward. The blade 5 is shown in a circular shape, but this is only an example.

A pressure roller (9) is installed on the table (1) so that it can move forward and backward at the top of the plate mold (7). Here, the 'forward-backward direction' refers to the direction in which materials are supplied and discharged.

The material supply unit 11 supplies the material 3 to be processed between the plate mold 7 and the pressure roller 9. The material (3) is composed of a material body (3a) that actually requires processing and a protective film (3b) covered on the material body (3a) to protect the surface of the pressure roller (9) from the blade (5). You can. The material body (3a) is supplied between the plate mold (7) and the pressure roller (9) by the material body supply unit (2), and the protective film (3b) is pressed with the plate mold (7) by the protective film supply unit (4). It is supplied between rollers (9). The punched film body (3a) is collected by the film body collection unit (21), and the protective film (3b) is collected by the protective film collection unit (23).

The pressure roller 9 rolls while pressing the upper surface of the plate-shaped mold 7 by the pressure roller transfer unit 110. The pressure roller transport unit 110 is engaged with the pressure roller transport motor 111 and the pinion 112 rotated by the pressure roller transport motor 111, and is a rack installed on the left and right sides of the upper surface of the table (1). (113) (see Figure 2). In addition, the pressure roller 9 is rotated around an axis (X) that is horizontal to the ground by the pressure roller rotation motor 121 during the pressure process.

Installation stands 125 are installed on the left and right sides of the table 1 to support both ends of the roll axis 10 of the pressure roller 9.

Configurations for moving the pressure roller 9 in the forward and backward directions may vary. Therefore, the scope of the present invention is not limited by what is shown. For example, a cylinder or screw rod may be used.

The core of the present invention lies in the plate mold lifting unit 120, which will be described below.

The plate mold lifting unit 120 raises the plate mold 7 so that the pressure roller 9 presses the plate mold 7 or lowers it to separate them, thereby preventing the pressure roller 9 from pressing the plate mold 7. Do not allow it.

According to this embodiment, the plate-shaped mold lifting unit 120 is installed on the upper surface of the table 1 to be able to move in the forward and backward directions, and includes a pair of push bars 213 and 215 whose upper surfaces 213a and 215a are inclined surfaces, A screw 211 that is screwed to the push bars 213 and 215 to move the push bars 213 and 215 in the forward and backward directions, a screw drive motor 210 that rotates the screw 211 on its axis, and the push bars 213 and 215. It includes a plate-shaped mold (7) placed on the upper surface and having inclined support surfaces (13, 15) in surface contact with the upper surfaces (213a, 215a) of the push bar. The push bars 213 and 215 are installed symmetrically to each other and operate symmetrically. The screw 211 is machined with a right-hand thread on one side and a left-hand thread on the other side, so that the push bars 213 and 215 move symmetrically in a straight line.

The plate mold 7 is guided by the guide frame 11 to prevent it from moving laterally.

According to this configuration, when the screw drive motor 210 operates to rotate the screw 211 in one direction, the gap between the push bars 213 and 215 is narrowed and the plate mold 7 is lifted. Also, on the contrary, if the screw 211 is rotated in the opposite direction, the gap between the push bars 213 and 215 widens and the plate mold 7 is lowered. In Figure 4, the narrowed state is shown as a dashed line, and the widened state is shown as a solid line. Figure 5(a) shows a state in which the plate mold 7 is raised and pressed by being narrowed, and Figure 5(b) shows a state in which the plate mold 7 is lowered and spaced apart from the pressurizing roller 9 by being widened. do.

As in the state of FIG. 5(a), the pressure roller 9 rotates to the right in the drawing to cut the material 3. Figure 5(b) shows a state in which the pressure roller 9 returns to its original state while moving to the left in the drawing.

As shown in FIG. 5(b), the pressure roller 9 is spaced apart from the plate-shaped mold 7 by the plate-shaped mold lifting unit 120 and is quickly returned to its original position. The direction in which the pressure roller 9 cuts the material 3 may change depending on the situation.

The pressure roller 9 can rotate with its own driving force by the pressure roller rotation motor 121 in the process of pressing the plate mold. During cutting work, the rotation speed and moving speed of the pressure roller (9) should be the same. In some cases, the pressure roller (9) may be rotated on its axis solely by the friction force generated between the plate-shaped molds (7).

The vertical movement distance of the plate mold (7), that is, the stroke (G), should be determined as small as possible so that no pressure is applied by the pressure roller.

In this way, the pressure roller 9 applies pressure in only one direction during the process of cutting the material 3. As a result, even if the material 3 is pushed during the pressing process, it is always pushed in one direction, so there is no deviation in the pattern of the cut material body 3a.

Hereinafter, another embodiment of the present invention will be described.

The configuration of the plate-shaped mold lifting unit 120 for elevating the plate-shaped mold 7 may vary. 6 to 8 relate to another example of the plate-shaped mold lifting unit 120.

The plate mold 7 can be moved in the vertical direction by the operation of the fixedly installed lifting cylinder 220. Two or more lifting cylinders 220 may be installed to balance forces. The lifting cylinder 220 is connected to the plate mold 7 through the horizontal bar 222 and the vertical bar 223. Figure 6(a) shows a state in which the plate mold 7 is raised, and Figure 6(b) shows a state in which the plate mold 7 is lowered. The piston 221 of the lifting cylinder is connected to the horizontal bar 222, allowing the plate mold to move up and down.

Hereinafter, description will be made with reference to FIG. 7.

Cam 230 The cam surface of is supported on the bottom of the plate mold 7. By rotation of the cam, the plate mold can rise as shown in Figure 7 (a) or descend as shown in Figure 7 (b). Cam driver 231 It may include a cam drive motor and a power transmission mechanism. The cam drive motor may be a servo motor whose rotation angle can be set.

A coil spring (not shown) may be installed between the plate mold and the table so that the plate mold receives elastic force in the downward direction.

Hereinafter, description will be made with reference to FIG. 8.

The plate-shaped mold lifting part 120'' of this embodiment includes a lifting drive motor 242, a screw rod 240, and a driving gear 241. The lifting driving motor 242 generates rotational force and moves through an electric gear. Rotate the fixedly installed driving gear 241. The driving gear 241 is engaged with the thread of the screw rod 240 in a fixed position. The upper end of the screw rod 240 is attached to the bottom of the plate mold 7. It is rotatably connected via a bearing. The lower end of the screw rod 240 extends downward through the table 1. As a result, the rotational movement of the drive gear 241 is performed by the screw rod 240 and the plate mold. It is converted into vertical linear motion in (7).

Figure 8(a) shows a state in which the screw rod 240 is raised by the lifting drive motor 242, and as a result, the pressure roller 9 presses and cuts the material 3. Figure 8(b) shows a state in which the plate-shaped mold 7 is lowered and separated from the pressure roller 9, making it impossible to cut the material 3.

The configuration shown and described above is nothing more than a preferred embodiment based on the technical idea of the present invention. Those skilled in the art will be able to make various changes based on common technical knowledge, but it should be noted that these may be included in the scope of protection of the present invention.
