Description

인쇄장치 {Printing Machine}Printing Machine {Printing Machine}

본 발명은 인쇄장치에 관한 것으로서, 특히 인쇄된 종이가 적재되는 딜리버리 유닛에 체인을 사용하여 종이를 이송하지 않고 트랜스퍼 실린더들을 사용하여 이송함으로써 인쇄속도를 향상시킬 수 있는 인쇄장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus, and more particularly, to a printing apparatus capable of improving printing speed by transferring using transfer cylinders without transferring paper using a chain to a delivery unit on which printed paper is loaded.

인쇄장치는 여러 가지가 있다. 흔히 가정용이나 사무용으로 사용되는 부피가 작은 인쇄장치들이 널리 사용되고 있으나, 사업적으로 크게 영위하는 경우에는 대형 인쇄장치가 사용되어 진다. 본 발명은 대형의 인쇄장치에 관한 것이다.There are many printing devices. Often, the bulky printing apparatuses used for home or office use are widely used, but large business apparatuses are used in the case of large business. The present invention relates to a large printing apparatus.

도 1을 참조하면, 종래의 인쇄장치가 개략적으로 도시되어 있다. 도면의 번잡함을 피하기 위하여 실린더(12) 상부의 각종 색깔의 잉크를 공급하게 되는 잉크 유닛은 생략되어 있다. 도 1에 도시된 바와 같이, 인쇄장치는 종이가 적재되어 공급되는 피더 유닛(feeder unit)(10)으로부터 동작이 시작된다. 피더 유닛(10)으로부터 나온 종이는 첫 번째 피더 실린더(14)를 거쳐 첫 번째 임프레션 실린더(impression cylinder)(13)를 거치면서 첫 번째 색이 인쇄되는 바, 그 색은 플레이트 실린더(plate cylinder)(11)와 블랭킷 실린더(blanket cylinder)(12)에 의해 잉크가 전달되어 임프레션 실린더 사이에서 인쇄가 이루어지게 된다. 인쇄가 이루어진 종이는 임프레션 실린더(13) 사이의 트랜스퍼 실린더(transfer cylinder)(15)에 의해 다른 임프레션 실린더로 옮겨져 두 번째 색이 인쇄되고 같은 방식으로 연속적으로 인쇄되면서 마지막 임프레션 실린더에 의해 인쇄된 다음 트랜스퍼 체인(20)으로 이송된다. 이때 임프레션 실린더(13)와 트랜스퍼 실린더(15) 사이에는 그립퍼(15a)가 설치되어 종이를 잡아 이송시키게 되는 것이다.Referring to Fig. 1, a conventional printing apparatus is schematically shown. The ink unit for supplying ink of various colors on the upper part of the cylinder 12 is omitted to avoid the complexity of the drawing. As shown in Fig. 1, the printing apparatus starts to operate from a feeder unit 10 to which paper is loaded and fed. The paper from the feeder unit 10 passes through the first feeder cylinder 14 and then through the first impression cylinder 13, where the first color is printed, which is the plate cylinder ( 11) and the blanket cylinder 12 (blanket cylinder) (12) to transfer the ink to print between the impression cylinder. The printed paper is transferred to another impression cylinder by a transfer cylinder 15 between the impression cylinders 13 so that the second color is printed and continuously printed in the same manner, followed by the last impression cylinder and then transfer Transferred to the chain (20). At this time, the gripper 15a is installed between the impression cylinder 13 and the transfer cylinder 15 to grab and transport the paper.

트랜스퍼 체인(20)에도 그립퍼(20a)가 설치되어 종이를 잡아 트랜스퍼 체인(20)을 따라 이송하게 되고, 인쇄가 완료된 종이는 트랜스퍼 체인(20)을 따라 이송되면서 체인 내부에 설치된 드라이어(21)에 의해 건조된 다음 딜리버리 유닛(delivery unit)(30)에 적재된다.The gripper 20a is also installed on the transfer chain 20 to grab paper and transfer it along the transfer chain 20, and the printed paper is transferred along the transfer chain 20 to the dryer 21 installed inside the chain. Dried and then loaded into a delivery unit 30.

그러나 종래기술에 의한 인쇄장치는 실린더를 통해 빠른 속도로 인쇄되면서 이송되는 종이가 건조되기 위해서 체인장치 쪽으로 이송되는데, 체인장치는 안정성이나 기타의 이유로 그 속도가 한정되어 있기 때문에 실린더들이 아무리 빠르고 신속하게 회전할 수 있다 하더라도 무거운 체인장치의 움직임이 직선운동에서 회전운동으로 바뀌고 또 다시 회전운동이 직선운동으로 바뀌기 때문에 더 이상 인쇄속도를 상승시킬 수 없는 문제점이 있다.However, the printing device according to the prior art is printed at a high speed through the cylinder and is conveyed to the chain device to dry the conveyed paper. The chain device is limited in speed due to stability or other reasons, so no matter how fast and fast the cylinders are. Even if it can rotate, the movement of the heavy chain device is changed from a linear motion to a rotational motion, and again the rotational motion is changed to a linear motion, there is a problem that can no longer increase the printing speed.

본 발명은 상술한 종래기술의 문제점을 해결하기 위하여 안출된 발명으로서, 체인장치 대신 트랜스퍼 실린더를 연속적으로 장착하여 구성함으로써 실린더 회전 속도를 상승시킬 수 있는 인쇄장치에 관한 것이다.The present invention has been made in order to solve the problems of the prior art described above, and relates to a printing apparatus capable of increasing the cylinder rotation speed by continuously mounting a transfer cylinder instead of a chain device.

이러한 본 발명에 의한 인쇄장치는 임프레션 실린더와 블랭킷 실린더 사이를 통과하면서 인쇄가 이루어지는 인쇄장치에 있어서, 마지막으로 인쇄가 이루어진 종이는 새로운 다수개의 트랜스퍼 실린더들을 통과하면서 인쇄된 종이가 적재되는 딜리버리 유닛으로 이송되되, 상기 새로운 트랜스퍼 실린더 내부 또는 외부에는 드라이어가 설치된 것을 특징으로 한다.The printing apparatus according to the present invention is a printing apparatus in which printing is performed while passing between an impression cylinder and a blanket cylinder, and finally, the printed paper is transferred to a delivery unit in which printed paper is loaded while passing through a plurality of new transfer cylinders. However, the new transfer cylinder inside or outside is characterized in that a dryer is installed.

여기서, 상기 새로운 트랜스퍼 실린더 내부에는 종이를 펴기 위한 공기를 토출하는 노즐이 설치된 것을 특징으로 한다.Here, the new transfer cylinder is characterized in that the nozzle for discharging the air for unfolding the paper is installed.

또, 상기 새로운 트랜스퍼 실린더 내부 또는 외부에는 드라이어 장치가 설치된 것을 특징으로 한다.In addition, a dryer device is installed inside or outside the new transfer cylinder.

본 발명에 의한 인쇄장치는 트랜스퍼 체인장치 대신에 트랜스퍼 실린더를 사용하여 종이를 이송시키는 방식이기 때문에 실린더의 회전속도의 상승에 따라 인쇄기계가 무리 없이 인쇄속도를 증가시킬 수 있는 효과를 제공한다.Since the printing apparatus according to the present invention transfers paper by using a transfer cylinder instead of the transfer chain apparatus, the printing machine increases the printing speed without difficulty as the cylinder's rotational speed is increased.

도 2를 참고하면, 피더 유닛(50)에 적재되어 있던 종이(100)는 피더 실린더(51)를 거쳐 임프레션 실린더(54)에 전달된다. 임프레션 실린더(54)로 이송된 종이(100)는 잉크 유닛의 플레이트 실린더(52) 아래의 블랭킷 실린더(53)와 맞물리면서 첫 번째 잉크 색의 인쇄가 이루어진다. 그 종이는 다시 트랜스퍼 실린더(55)의 그립퍼(55a)에 고정된 채 이송되고, 다른 임프레션 실린더에 전해져 두 번째 잉크 색의 인쇄가 이루어지게 된다. 이것은 종래기술과 같은 동작으로 이루어진다. 이렇게 여러 색의 인쇄가 이루어지면 인쇄가 완료되며, 완료된 종이는 마지막 인쇄가 이루어진 임프레션 실린더로부터 떠나 새로운 트랜스퍼 실린더(60-66)로 이송된다. 새로운 트랜스퍼 실린더(60-66)에는 각각 그립퍼(60a-66a)가 설치되어 종이를 고정하여 이송시키게 되는데, 그 중앙에 잉크를 건조하기 위한 드라이어(60b-64b)가 설치되어 있다. 이러한 새로운 트랜스퍼 실린더(60-66)는 크기가 다르거나 같은 여러 개가 서로 연결되어 종이를 이송하게 되고, 마지막 새로운 트랜스퍼 실린더(66)의 그립퍼(66a)가 종이(100)를 딜리버리 유닛(80)에 놓음으로써 인쇄된 종이가 적재된다.Referring to FIG. 2, the paper 100 loaded on the feeder unit 50 is transferred to the impression cylinder 54 via the feeder cylinder 51. The paper 100 transferred to the impression cylinder 54 is engaged with the blanket cylinder 53 under the plate cylinder 52 of the ink unit to print the first ink color. The paper is again transported fixedly to the gripper 55a of the transfer cylinder 55 and transferred to another impression cylinder to print the second ink color. This is done with the same operation as the prior art. When the multi-color printing is performed, the printing is completed, and the completed paper is transferred from the impression cylinder on which the last printing was made and transferred to a new transfer cylinder 60-66. The new transfer cylinders 60-66 are respectively provided with grippers 60a-66a to fix and transport the paper, and dryers 60b-64b for drying the ink are installed in the center thereof. These new transfer cylinders 60-66 are connected to each other by different sizes or the same size to transfer paper, and the gripper 66a of the last new transfer cylinder 66 transfers the paper 100 to the delivery unit 80. By placing, the printed paper is loaded.

도 2를 다시 참고하면, 인쇄가 이루어진 종이(100)는 다수개의 새로운 트랜스퍼 실린더(60-66)를 통과하여 이송되되, 상기 새로운 트랜스퍼 실린더(60-66) 중에는 중앙에 내부 드라이어(60b-64b)가 설치되어 있는 것도 있고, 개중에는 외부 드라이어(70,71)가 설치된 것도 있다.Referring again to FIG. 2, the printed paper 100 is transported through a plurality of new transfer cylinders 60-66, with an internal dryer 60b-64b at the center of the new transfer cylinders 60-66. Some are provided, and some are provided with external dryers 70 and 71.

도 3을 참고하면, 종이(100)의 이송원리를 알 수 있다. 임프레션 실린더(54) 사이에 트랜스퍼 실린더(55)가 설치되어 있고, 임프레션 실린더에는 두개의 그립퍼(54a)가 있고 트랜스퍼 실린더(55)에는 세 개의 그립퍼(55a)가 설치되어 있다. 임프레션 그립퍼에 잡힌 종이는 트랜스퍼 실린더의 그립퍼로 종이가 옮겨 잡히게 하고, 그 다음에 다시 임프레션 실린더의 그립퍼에 잡히도록 하면서 종이가 연속적으로 인쇄가 이루어지면서 이송되는 것이다.Referring to Figure 3, the transfer principle of the paper 100 can be seen. The transfer cylinder 55 is provided between the impression cylinders 54, two grippers 54a are provided in the impression cylinder, and three grippers 55a are provided in the transfer cylinder 55. As shown in FIG. The paper caught in the impression gripper transfers the paper to the gripper of the transfer cylinder, and then the paper is continuously gripped by the gripper of the impression cylinder while the paper is continuously printed.

도 4 내지 7을 참고하면, 새로운 트랜스퍼 실린더(64)의 모양을 볼 수 있다. 외부에 세 개의 그립퍼(64a)가 설치되어 있고, 중앙에는 내부 드라이어(64b)가 설치되어 있다. 따라서 이송중인 종이의 잉크가 어느 정도 건조되도록 하게 된다. 도 5는 새로운 트랜스퍼 실린더의 측면도로서, 중앙에 고정축(S)이 있고, 그 주위를 트랜스퍼 몸체가 그립퍼와 함께 회전하는 구조를 가지고 있다.4 to 7, the shape of the new transfer cylinder 64 can be seen. Three grippers 64a are provided on the outside, and an internal dryer 64b is provided on the center. Therefore, the ink of the paper being transferred is allowed to dry to some extent. 5 is a side view of the new transfer cylinder, with a fixed shaft S at the center, and a structure in which the transfer body rotates with the gripper around it.

도 8을 참고하면, 왼쪽의 도면은 새로운 트랜스퍼 실린더(66) 중에 마지막에 설치된 것을 나타내는데, 그 실린더(66)에는 세 개의 공기 노즐(67)이 설치되어 종이를 펴주게 되는 것이다. 오른쪽 그림에 도시된 바와 같이 종이가 잡힌 방향으로 평행하게 노즐(67)이 설치되어 종이(100)에 공기를 가하여 펴주게 된다.Referring to FIG. 8, the figure on the left shows that the new transfer cylinder 66 is installed last, and the cylinder 66 is provided with three air nozzles 67 to unfold the paper. As shown in the figure on the right, the nozzles 67 are installed in parallel in the direction in which the paper is held to apply the air to the paper 100 to spread it out.
