본 고안은 롤(Roll)의 형태로 감겨진 소재를 소정의 가공기계에 공급하기 위한 공급장치에 관한 것으로, 특히 정밀인쇄기와 같이 소재(피인쇄물)의 일정한 텐션(Tension)이 요구되는 기계에 적용하여 피인쇄물이 자동적으로 설정된 텐션을 유지할 수 있게 한 것이다.The present invention relates to a feeding device for supplying a material wound in the form of a roll to a predetermined processing machine. Especially, it is applied to a machine requiring a constant tension of a material (subject), such as a precision printing machine. This allows the substrate to automatically maintain the set tension.

일반적으로 각종 필름류나 장판지 원단등을 인쇄하는 정밀인쇄기에서는 피인쇄물의 정확한 공급이 요구되며, 피인쇄물을 정확히 공급하기 위해서는 롤형태로 된 피인쇄물의 텐션이 일정하게 유지되어야 한다.In general, a precise printing machine for printing various films or longboard fabrics, etc. requires accurate supply of the printed matter, and in order to accurately supply the printed matter, the tension of the printed matter in the form of a roll must be kept constant.

또한 종래의 정밀인쇄기는 제3도에 도시한 바와 같이 롤(21)에 감겨져 있는 피인쇄물(11)이 이 다수개의 안내롤(22)을 거친 후 구동모터(M)의 당기는 힘에 의해 인쇄기에 공급되도록 되어 있으며, 이때 피인쇄물(11)의 텐션은 안내롤(22)의 배치 및 재질에 의해 유지된다.In addition, the conventional precision printing machine, as shown in FIG. 3, after the to-be-printed material 11 wound on the roll 21 passes through the plurality of guide rolls 22, is pulled by the driving motor M by the pulling force of the printing machine. In this case, the tension of the to-be-printed object 11 is maintained by the arrangement and the material of the guide roll 22.

그러나 상기와 같은 종래의 장치는 인쇄작업시 공급되는 피인쇄물의 텐션이 단지 안내롤(22)의 재질과 배열에 의해 유지되도록 되어 있기 때문에 피인쇄물의 종류나 무게 또는 주위환경(온도, 습도등)의 변화시 피인쇄물의 텐션변화가 일어나게 되고 이러한 경우 인쇄위치가 틀어지는 등 인쇄불량의 원인이 된다.However, in the conventional apparatus as described above, since the tension of the to-be-printed material supplied during the printing operation is maintained only by the material and arrangement of the guide roll 22, the type or weight of the to-be-printed object or the ambient environment (temperature, humidity, etc.) In this case, the tension of the to-be-printed object is caused, and in this case, the printing position is distorted.

본 고안은 피인쇄물의 종류나 무게 또는 주위환경이 변화되는 경우에도 피인쇄물이 항상 일정 텐션을 유지한 상태로 인쇄기에 공급될 수 있는 장치를 제공하기 위한 것이다.The present invention is to provide a device that can be supplied to the printing machine in a state in which the to-be-printed object always maintains a constant tension even when the type or weight of the to-be-printed object or the surrounding environment changes.

상기한 목적을 달성하기 위해 본 고안의 장치에는 일정한 공기압을 기준으로 부가되는 텐션(장력)값의 차에 의해 구동하는 벨로팜 실린더(Belopharm Cylinder)가 설치되어 있고 이 벨로팜 실린더의 구동값을 전기적 신호로 변환시켜 구동모터를 제어함에 따라 피인쇄물은 항상 일정 텐션을 유지하게 된다.In order to achieve the above object, the device of the present invention is provided with a bellow palm cylinder driven by a difference in tension (tension) value which is added based on a constant air pressure. By controlling the driving motor by converting it into a signal, the to-be-printed body always maintains a constant tension.

이하 본 고안 장치를 첨부도면 제1도와 제2도를 참조하여 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 and 2.

첨부도면 제1도는 본 고안 장치를 인쇄기에 적용한 일예를 나타낸 구성도로서 본 고안 장치는 롤(1)에 감겨져 있는 피인쇄물(11)을 안내하기 위한 수개의 안내롤(2)의, 피인쇄물을 피딩(Feeding) 하기 위한 공급용 모터(M1)와 인쇄구동 모터(M2), 승, 하강 운동이 가능한 터치롤(3), 피인쇄물의 텐션 변화에 따라 좌, 우로 이동하는 이동 인쇄롤(4), 이동 안내롤에 가해지는 텐션값과 공기압의 비교에 의해 작동하는 벨로팜 실린더(5), 벨로팜 실린더의 피스턴 로드에 연결된 연결암(6), 연결측에 고정된 구동기어(7), 구동기어와 이동안내롤의 회전중심이 되는 회전축(8), 구동기어(7)와 맞물린 저항 볼륨(9), 저항 볼륨의 회전 중심이 되는 회전축(10)등으로 구성되어 있다.1 is a block diagram showing an example in which the device of the present invention is applied to a printing machine, and the device of the present invention shows a plurality of guide rolls 2 for guiding the to-be-printed object 11 wound on the roll 1. Supply motor (M 1 ) and the print drive motor (M 2 ) for feeding, the touch roll (3) capable of raising and lowering movement, the moving printing roll moving to the left and right in accordance with the tension change of the substrate ( 4), the bellow palm cylinder (5) operated by comparing the tension value applied to the moving guide roll with the air pressure, the connection arm (6) connected to the piston rod of the bellow palm cylinder, and the driving gear (7) fixed to the connection side And a rotation shaft 8 serving as the center of rotation of the drive gear and the movement guide roll, a resistance volume 9 engaged with the drive gear 7, and a rotation shaft 10 serving as the center of rotation of the resistance volume.

벨로팜 실린더(5)의 공기압은 피인쇄물이 적절한 텐션을 유지하면서 공급되는 상태와 일치하는 압력으로 미리 설정되며, 이동안내롤(4)에 가해지는 압력(텐션값)이 벨로팜 실린더의 설정압력보다 낮으면 피스톤 로드가 전진하고 반대로 설정압력보다 높으면 후진하게 되어 있다.The air pressure of the bellow palm cylinder 5 is preset to a pressure consistent with the state in which the to-be-printed object is supplied while maintaining an appropriate tension, and the pressure (tension value) applied to the movement guide roll 4 is the set pressure of the bellow palm cylinder. If it is lower, the piston rod moves forward and vice versa if it is higher than the set pressure.

또한 저항 볼륨(9)은 공급용 모터(M1)와 전기적으로 연결되어 저항 볼륨의 저항값에 따라 공급용 모터의 회전속도가 가변된다.In addition, the resistance volume 9 is electrically connected to the supply motor M 1 so that the rotational speed of the supply motor varies according to the resistance value of the resistance volume.

상기와 같이 된 본 고안 장치의 작동과 그 효과를 설명한다.The operation and effects of the inventive device as described above will be described.

인쇄 작업시 롤(1)에 감겨져 있는 피인쇄물(11)은 각 안내롤(2), 공급용 모터(M1), 이동안내롤(4), 안내구동 모터(M2)를 거쳐 인쇄기에 공급되며, 인쇄시 피인쇄물의 텐션이 변화하는 경우 벨로팜 실린더(5)가 작동하여 피인쇄물의 텐션을 설정된 일정한 텐션으로 유지시키게 된다.The to-be-printed object 11 wound on the roll 1 at the time of printing operation is supplied to the printing machine through each guide roll 2, the supply motor M 1 , the movement guide roll 4, and the guide driving motor M 2 . If the tension of the to-be-printed object is changed during printing, the bellowpal cylinder 5 is operated to maintain the tension of the to-be-printed object at a predetermined constant tension.

즉, 피인쇄물이 설정된 적절한 텐션으로 공급되는 경우에는 이동안내롤(4)을 통과하는 피인쇄물에 의해 이동안내롤에 가해지는 압력이 벨로팜 실린더(5)에 설정된 공기압과 같게 되어 제2도(a)와 같이 벨로팜 실린더는 작동하지 않지만, 피인쇄물의 종류나 무게 또는 주위여건 변화에 의해 피인쇄물의 텐션이 변화되는 경우에는 즉시 벨로팜 실린더(5)가 작동하여 텐션을 교정하여 주게 된다.That is, when the to-be-printed object is supplied with the appropriate tension set, the pressure applied to the to-be-rolled guide roll by the to-be- passed through the moving guide roll 4 becomes equal to the air pressure set in the bellow palm cylinder 5, and the second degree ( As in a), the bellow palm cylinder does not work, but when the tension of the print is changed by the change of the type, weight, or ambient conditions of the print, the bellow palm cylinder (5) operates immediately to correct the tension.

예를 들어 피인쇄물의 텐션이 기준값보다 낮아지면 이동안내롤(4)에 가해지는 압력이 작아져 벨로팜 실린더(5)에 설정된 공기압보다 낮아지게 되고 이때 벨로팜 실린더(5)가 즉시 작동하여 피스턴 로드가 상승하게 되며, 피스턴 로드가 상승할때 제2도 (b)의 일점쇄선 도시와 같이 연결암(6)과 구동기어(7)는 회전축(8)을 중심으로 도면상 시계방향의 회전을 하게 된다.For example, when the tension of the to-be-printed object is lower than the reference value, the pressure applied to the movement guide roll 4 becomes lower than the air pressure set in the bellow palm cylinder 5, and at this time, the bellow palm cylinder 5 is immediately operated and the piston As the rod rises, when the piston rod rises, the connecting arm 6 and the drive gear 7 rotate clockwise in the drawing about the rotation shaft 8 as shown by the dashed-dotted line in FIG. Done.

따라서 이동안내롤(4)은 제2도(b)의 일점쇄선 도시와 같이 도면상 좌측방향으로 이동하여 피인쇄물을 팽팽하게 당겨주게 된다.Therefore, the movement guide roll 4 moves to the left in the drawing as shown by the dashed-dotted line in FIG.

한편 구동기어(7)에 맞물린 저항 볼륨(9)은 회전축(10)을 중심으로 반시계 방향의 회전을 하게 되고 이러한 저항 볼륨의 반시계 방향 회전에 의해 공급용 모터(M1)의 회전속도가 감소하게 되므로 공급용 모터(M1)와 인쇄구동 모터(M2) 사이의 피인쇄물은 일정텐션을 유지하게 된다.On the other hand, the resistance volume 9 engaged with the drive gear 7 is rotated counterclockwise about the rotation shaft 10, and the rotation speed of the supply motor M 1 is increased by the counterclockwise rotation of the resistance volume. Since it is reduced, the to-be-printed between the supply motor M 1 and the print drive motor M 2 maintains a constant tension.

반대로 이동안내롤(4)에 가해지는 압력의 벨로팜 실린더(5)의 설정 공기압보다 높아지면 전술한 바와는 반대로 제2도의 실선도시와 같이 벨로팜 실린더의 피스턴 로드가 하강함과 동시에 연결암(6)과 구동기어(7)가 반시계 방향의 회전을 하게 되며, 저항 볼륨(9)은 시계방향의 회전을 하고 공급용 모터(M1)의 회전속도는 증가하게 된다.On the contrary, when the air pressure higher than the set air pressure of the bellows palm cylinder 5 is applied to the movement guide roll 4, the piston rod of the bellows palm cylinder descends and the connecting arm ( 6) and the drive gear 7 is rotated in the counterclockwise direction, the resistance volume 9 is rotated in the clockwise direction and the rotational speed of the supply motor (M 1 ) is increased.

이상에서와 같이 본 고안은 미리 설정된 공기압과 실제 부과되는 텐션값을 비교하여 그 차이값에 의해 동작하는 벨로팜 실린더를 피인쇄물의 공급 경로상에 설치하고 이 벨로팜 실린더의 동작에 의해 공급용 모터의 속도를 제어하여 공급용 모터와 인쇄기 구동모터사이의 텐션을 항상 일정하게 유지시킬 수 있으므로 피인쇄물의 텐션변화에 따라 야기되는 인쇄불량을 방지할 수 있게 된다.As described above, the present invention compares a preset air pressure with an actual tension value, and installs a bellow palm cylinder operated by the difference value on the supply path of the to-be-printed object. Since the tension between the supply motor and the printer driving motor can be kept constant at all times by controlling the speed of, the printing defect caused by the tension change of the to-be-printed material can be prevented.
