인쇄기의 배출용지 적재장치{PRINTED PAPER LOADING APPARATUS FOR PRINTER}Ejection paper loading device of printing machine {PRINTED PAPER LOADING APPARATUS FOR PRINTER}

본 발명은 인쇄기의 배출용지 적재장치에 관한 것으로서, 더욱 상세하게는 인쇄되어 배출되는 배출용지가 흐트러지거나 구겨짐이 없이 올바르게 적재될 수 있는 인쇄기의 배출용지 적재장치에 관한 것이다.The present invention relates to a discharge paper stacking device for a printing press, and more particularly, to a discharge paper stacking device for a printing press that can be correctly loaded without being disturbed or wrinkled printed discharge paper.

일반적으로 인쇄기는 인쇄용지를 공급하기 위한 인쇄공급부와, 인쇄공급부로부터 공급된 인쇄용지에 인쇄를 하는 인쇄부와, 인쇄부에 의해 인쇄된 용지를 배출하는 인쇄용지 배출부와, 인쇄용지 배출부로부터 배출되는 인쇄된 용지인 배출용지를 적재하는 인쇄된 용지 적재부가 구비되어 있다.Generally, a printing machine is provided with a printing supply unit for supplying printing paper, a printing unit for printing on the printing paper supplied from the printing supply unit, a printing paper discharge unit for discharging the paper printed by the printing unit, and a printing paper discharge unit. There is provided a printed paper stack for loading discharge paper which is printed paper to be discharged.

그리고, 인쇄용지는 다수의 로울러에 의해 상기의 인쇄공급부, 인쇄부, 인쇄용지 배출부, 인쇄된 용지 적재부에 순자차적으로 이동된다. Then, the printing paper is sequentially moved by the plurality of rollers to the printing supply unit, the printing unit, the printing paper discharge unit, and the printed paper loading unit.

특히, 종래의 인쇄기에서 인쇄된 용지 적재부는 인쇄용지 배출부의 배출롤러에 의해 배출되는 상기 배출용지를 용지적재판에 순차적으로 적재하였다.In particular, the paper stack printed in the conventional printing press sequentially loaded the discharge paper discharged by the discharge roller of the printing paper discharge portion on the paper loading plate.

그러나, 인쇄된 용지가 적재되는 과정에서 배출용지의 적재높이가 증가됨으로써, 연속적으로 인쇄되어 배출되는 배출용지가 기적재된 배출용지의 상부에 올바르게 적재되지 못하고, 기적재된 용지에 걸리어 흐트러지거나, 구겨지게 되는 문제 점이 있었다.However, as the stack height of the discharge paper is increased in the process of loading the printed paper, the discharge paper continuously printed and discharged may not be properly stacked on top of the loaded discharge paper, and may be jammed or jammed on the loaded paper. There was a problem with being crumpled.

이에, 용지적재판의 하부에 탄성부재(압축스프링)을 구비하여 적재된 배출용지의 자중에 의해 용지적재판이 상하로 이동되게 한 인쇄기가 개발되었다. Accordingly, a printer has been developed in which an elastic member (compression spring) is provided below the paper loading plate to move the paper loading plate up and down by the weight of the discharge paper loaded.

그러나, 용지적재판의 상하이동이 적재되는 배출용지의 자중에 의해 이루어지므로, 배출용지가 비교적 가벼운 용지일 경우에는 용지적재판이 충분히 하강되지 못하므로 여전히 배출용지가 기적재된 용지에 걸리는 문제점이 있었다.However, since the shanghai-dong of the paper-loading plate is made by the weight of the discharge paper loaded, the paper-loading plate is not sufficiently lowered when the paper is relatively light, so there is still a problem that the paper is loaded on the paper. .

본 발명은 상기 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 인쇄된 배출용지가 기적재된 배출용지에 걸리지 않고 용지적재판에 올바르게 적재되도록 하는 데에 있다.The present invention is to solve the problems of the prior art, an object of the present invention is to ensure that the printed discharge paper is correctly loaded on the paper loading plate without being caught on the discharged paper.

Of course, the ratchet 62 is provided with an interference protrusion 97 that interferes with the lever 65.

솔레노이드(66)는 자기장에 의해 로드(66a)가 진퇴되는 것으로, 로드(66a)가 레버(65)의 타측, 즉 압축스프링(96)에 연결된 부위에 연결되어 있다.The solenoid 66 is a rod 66a is advanced and retracted by a magnetic field, and the rod 66a is connected to the other side of the lever 65, that is, the portion connected to the compression spring 96.

이하에서는, 이와 같이 구성된 본 실시 예의 작용 및 효과에 대해 설명한다.Hereinafter, the operation and effects of the present embodiment configured as described above will be described.

도 3을 참조하면, 본 실시 예는 배출롤러(20)로부터 인쇄된 배출용지(30)가 배출되어 용지적재판(40)에 적재된다. 이때, 프레임(10)에 설치된 배출용지 감지센서(70)(적외선 센서등)에 의해 용지적재판(40)에 적정 적재높이로 적재된 배출용지(30)가 감지되면, 콘트롤부(80)에 의해 솔레노이드(66)가 제어된다.Referring to FIG. 3, in the present embodiment, the discharge paper 30 printed from the discharge roller 20 is discharged and loaded on the paper loading plate 40. At this time, when the discharge paper 30 loaded at the proper stacking height on the paper loading plate 40 by the discharge paper sensor 70 (infrared sensor, etc.) installed in the frame 10, the control unit 80 The solenoid 66 is controlled by this.

콘트롤부(80)의 제어로 솔레노이드(66)가 구동되면, 레버(65)가 회동되고, 래칫(62)은 래칫기어(61)를 간섭하게 된다. 이때, 배출롤러(20)를 회전시키는 동력 원에 의해 주기적으로 양방향회전하는 래칫회전판(63)에 의해 래칫(62)이 래칫기어(61)를 간섭하여 간헐적으로 회전시키게 된다. When the solenoid 66 is driven by the control of the controller 80, the lever 65 is rotated, and the ratchet 62 interferes with the ratchet gear 61. At this time, the ratchet 62 is intermittently rotated by the ratchet rotating plate 63 which periodically rotates bidirectionally by the power source for rotating the discharge roller 20 to interfere with the ratchet gear 61.

래칫기어(61)가 회전되면 제1베벨기어(91), 제2베벨기어(92), 웜기어(93), 윔휠(94)이 순차적으로 연동되어 회전되면서 구동스프로킷(64)이 회전된다. 이에, 체인(52)이 무한궤도로 회전되면서 용재적재판(40)이 하강된다.When the ratchet gear 61 is rotated, the driving sprocket 64 is rotated while the first bevel gear 91, the second bevel gear 92, the worm gear 93, and the wheel wheel 94 are rotated in sequence. Thus, while the chain 52 is rotated in an infinite track, the slab plate 40 is lowered.

한편, 배출용지 감지센서(70)에 의해 배출용지(30)가 감지되지 않게 되면, 콘트롤부(80)의 제어로 솔레노이드(66)는 구동이 정지된다. 이때, 레버(65)는 압축스프링(96)의 탄성력에 의해 회동되고, 레버(65)는 래칫(62)을 간섭하여 래칫기어(61)로부터 이격시키게 된다.On the other hand, when the discharge paper 30 is not detected by the discharge paper sensor 70, the solenoid 66 is stopped by the control of the control unit 80. At this time, the lever 65 is rotated by the elastic force of the compression spring 96, the lever 65 is spaced apart from the ratchet gear 61 by interfering with the ratchet 62.

따라서, 배출롤러(20)를 회전시키는 동력원에 의해 래칫회전판(63)이 주기적으로 양방향 회전되더라도, 래칫(62)이 래칫기어(61)로부터 이격되어 있어 래칫기어(61)는 회전되지 않게 되고, 용지적재판(40)은 정지된다.Therefore, even if the ratchet rotating plate 63 is periodically bidirectionally rotated by the power source for rotating the discharge roller 20, the ratchet 62 is spaced apart from the ratchet gear 61 so that the ratchet gear 61 is not rotated. The paper stacking plate 40 is stopped.

한편, 용지적재판(40)에 일정량의 배출용지(30)가 적재되면 배출용지(30)를 용지적재판(40)으로부터 들어내어 옮기고, 하강된 용지적재판(40)을 상승시키기 위해 구동모터(53)를 구동시키게 된다.On the other hand, when a certain amount of discharge paper 30 is loaded on the paper loading plate 40, the discharge paper 30 is lifted out of the paper loading plate 40 and moved, and the drive motor to raise the lowered paper loading plate 40 53 will be driven.

구동모터(53)의 구동으로 체인(52)을 무한궤도로 회전시켜 용지적재판(40)을 상승시키게 된다. 이때, 구동스프로킷(64)은 체인(52)으로부터 이격시킨다. 물론 구동스프로킷(64)은 체인(52)으로부터 이격될 수 있도록 프레임(10)에 슬라이딩가능하게 설치된다.By driving the drive motor 53, the chain 52 is rotated in an endless track to raise the paper stacking plate 40. At this time, the drive sprocket 64 is spaced apart from the chain 52. Of course, the drive sprocket 64 is slidably mounted to the frame 10 so as to be spaced apart from the chain 52.

이와 같이, 용지적재판을 적재된 배출용지의 적재높이에 따라 자동으로 하강 시킬 수가 있어, 배출되는 용지가 기적재된 용지에 걸리어 흐트러지거나 구겨짐이 없이 원활히 적재된다.In this way, the paper stacking plate can be automatically lowered according to the stacking height of the stacked discharge paper, so that the discharged paper is smoothly loaded without being disturbed or wrinkled by the loaded paper.
