As shown, the roll printing apparatus of the present invention is composed of an ink roller 10, a blanket roller 20 and the roll separation means (30).

The ink roller 10 is formed in a cylindrical shape having a predetermined diameter made of a metal material, and is formed to have a width corresponding to the size of the substrate 100, and a rotating shaft 12 is coupled to a central portion thereof, and the substrate 100 is formed on an outer circumferential surface thereof. The predetermined pattern 15 to be transferred to is formed.

 The rotating shaft 12 is rotatably installed at both ends of the main frame (not shown), and receives the rotational force from a separate driving motor (not shown) to rotate the ink roller 10 at a constant speed.

On the other hand, an ink supply device (not shown) that is separately installed uniformly applies ink to the entire outer circumferential surface of the ink roller 10 that is rotated together with the rotating shaft 12, thereby forming a predetermined pattern 15 on the outer circumferential surface of the ink roller 10.

The linear plate 55 is provided in a plate shape having the same shape as the linear plates 35 and 45 of the embodiments of FIGS. 1 and 2, but the upper plate 55 protrudes upward at a predetermined interval to be engaged with the teeth 52. A tooth 58 formed therein is provided, and a support 57 and a stopper 56 are sequentially protruded upward from the rear end thereof.

The support 57 is formed at a position where the rotation shafts 12 and 22 are moved upward to the upper surface precisely at the time when the transfer of the pattern 15 is completed.

Meanwhile, the teeth 52 and the teeth 58 of the linear plate 55 may be connected to a general rack and pinion for more accurate relative motion.

The operation process will be described in detail below.

As shown in FIG. 3A, the rotating shafts 12 and 22 are rotated so that the pattern 15 from the ink roller 10 to the blanket roller 20 or the blanket roller 20 to the substrate 100. When the transfer begins, the linear plate 55 slides in the rotational direction of the rotary shafts 12 and 22 by engaging the teeth 58 with the teeth 52 of the rotary shafts 12 and 22.

At this time, as shown in (b), the rotary shafts 12 and 22 are raised from the endpoint 15a (shown in FIG. 1) of the pattern 15 to the upper surface of the support 57, and upward by 'B'. The ink roller 10 and the blanket roller 20, the blanket roller 20 and the substrate 100 are separated from each other.

The stopper 56 is in contact with the teeth 52 to prevent further sliding of the linear plate 55.

5 and 6 show another embodiment of the roll separation means of the present invention, except for the configuration of the roll separation means and the same as the above embodiment will be described only the changed configuration.

The roll separation means 60 is composed of a tooth 62, a support 63 and a linear plate 65 formed on the outer circumferential surface of the rotation shaft (12, 22).

The teeth 62 are formed on the outer circumferential surfaces of both ends of the rotation shafts 12 and 22, respectively, as shown in FIG. 6, and protrude to be arranged at regular intervals, but one side of the support 63 is not formed with teeth. It is provided to be formed.

The support part 63 is formed at a position where the rotation shafts 12 and 22 can be accurately moved upward at the time when the transfer of the pattern 15 is completed in the transfer process of the pattern 15.

Meanwhile, the linear plate 65 is protruded and arranged at regular intervals such that the teeth 68 are engaged with the teeth 62 of the rotation shafts 12 and 22 on the upper surface as in the embodiment of FIG. 3. A stopper 66 protrudes from the end.

The operation process is as follows.

As shown in FIG. 5A, the rotating shafts 12 and 22 are rotated so that the pattern 15 from the ink roller 10 to the blanket roller 20 or the blanket roller 20 to the substrate 100. When this transfer begins, the linear plate 65 slides in the rotational direction with the teeth 68 engaged with the teeth 62 of the rotational shafts 12, 22.

At this time, as shown in (b), the rotary shafts 12 and 22 are supported by the support 63 at the moment when the endpoint 15a (shown in FIG. 1) of the pattern 15 comes into contact with the counterpart. ) To be moved upward by 'C' and thus the ink roller 10, the blanket roller 20, the blanket roller 20, and the substrate 100 are separated from each other.

On the other hand, the stopper 66 is in contact with the support portion 63 to prevent further sliding of the linear plate (65).

7 and 8 show another embodiment of the roll separation means of the roll printing apparatus of the present invention, respectively, the same as the above embodiment except for the configuration of the roll separation means will be described only the changed configuration.

As shown in (a) and (b) of Figure 7, the roll separation means 70 is composed of a first gear member 71 and the second gear member (78).

The first gear member 71 and the second gear member 78 are extrapolated to both ends of the rotary shafts 12 and 22, respectively, and are rotatably installed integrally with the rotary shafts 12 and 22. Since the diameter is smaller than the diameter of the ink roller 10 and the blanket roller 20 is provided with a diameter that can be engaged with each other in consideration of this.

The first gear member 71 has a tooth portion 72 and a support portion 73 formed on the outer circumferential surface in the same manner as the tooth portion 62 and the support portion 63 shown in FIG. 5.

On the other hand, the second gear member 78 has a tooth portion 79 is formed on the outer peripheral surface to be engaged with the first gear member (71).

Therefore, as shown in (a), when the rotation shaft 12 is rotated by the drive motor, the first gear member 71 and the second gear member 78 engaged therewith are rotated, whereby the blanket roller 20 is The ink roller 10 and the outer circumferential surface are rotated in close contact with each other so that the pattern 15 is transferred from the ink roller 10.

In addition, as shown in (b), when the support portion 73 comes into contact with the teeth 79 of the second gear member 78 by the rotation of the first gear member 71, the first gear member 71 ) Moves upward by 'D' so that the ink roller 10 and the blanket roller 20 are separated from each other.

At this time, when the rotation of the ink roller 10 is stopped through the control unit, the blanket roller 20 also stops rotating.

Therefore, the embodiment of FIG. 7 only needs to control the rotation of the ink roller 10 in the process of transferring the pattern 15 from the ink roller 10 to the blanket roller 20.

The transfer of the pattern 15 from the blanket roller 20 to the substrate 100 is performed by installing the linear plate 55 of the shaft shifting means 50 shown in FIG. 3 on the second gear member 78. May be achieved by rotating

Meanwhile, the roll separation means 80 shown in FIG. 8 includes a first gear member 81, a second gear member 84, and a linear plate 85.

The first gear member 81 and the second gear member 84 are formed in the same manner, and are extrapolated and coupled to the rotation shafts 12 and 22, respectively, in the same manner as the second gear member 78 shown in FIG. Teeth 82 and 89 are arranged on the outer circumferential surface, respectively.

The diameter of the first gear member 81 and the second gear member 84 is formed to an appropriate size such that the outer peripheral surfaces of the ink roller 10 and the blanket roller 20 are in close contact with each other.

Meanwhile, the linear plate 85 is disposed between the first gear member 81 and the second gear member 84 so as to be horizontally moved. The first and second gear members 81 and the second surface are provided on the upper and lower surfaces. Tooth portions 88 are arranged to be engaged with the gear member 84 so as to be movable.

In addition, a support 87 is protruded from the rear end of the upper surface of the linear plate 85.

The support 87 is formed at a position where the rotation shaft 12 can be moved upward because the first gear member 81 is correctly raised to the upper surface at the time when the transfer of the pattern 15 is completed.

The operation process is as follows.

As shown in (a), when the rotation shaft 12 is rotated by the drive motor, the first gear member 81 is rotated, and the linear plate 85 engaged therewith moves in the rotation direction of the rotation shaft 12. do.

In addition, when the linear plate 85 moves, the second gear member 84 engaged with the lower surface tooth 88 rotates in conjunction with the pattern plate 15 of the ink roller 10 while the blanket roller ( 20) will be transferred to.

In addition, as shown in (b), when the linear plate 85 is moved by the rotation of the first gear member 81, the first gear member 81 is a support (at the time when the pattern 15 is finished) 87) By moving upward, the rotating shaft 12 is moved upward by 'E' so that the ink roller 10 and the blanket roller 20 are separated from each other.

At this time, when the rotation of the ink roller 10 is stopped through the control unit, the linear plate 85 is also stopped. Accordingly, the rotation of the rotating shaft 22 is stopped to stop the blanket roller 20.

Therefore, the transfer of the pattern 15 from the ink roller 10 to the blanket roller 20 only needs to control the rotation of the ink roller 10.

On the other hand, the transfer of the pattern 15 from the blanket roller 20 to the substrate 100 is performed by transferring the linear plate 55 of the roll separation means 50 shown in FIG. 84 may be achieved by rotating the rotary shaft 22.

Therefore, in the present invention, when the pattern 15 is sequentially transferred to the ink roller 10, the blanket roller 20, and the substrate 100, the ink roller 10 and the blanket after the transfer of the pattern 15 are completed, respectively. The roller 20 and the substrate 100 can be separated from each other at an accurate time point, thereby preventing the rolling of the pattern 15 through accurate transfer of the pattern 15, and applying a roll separation means having a simple structure. 15) The reliability of the company can be secured, thus reducing the cost of equipment and simplifying maintenance.
