본 발명은 지관절단장치에 있어서 지관을 지관고정장치에 의해 견고하게 고정된 상태로 회전될 수 있도록 하므로써 지관의 절단을 용이하게 하기 위한 지관의 고정 및 회전장치에 관한 것이다.The present invention relates to a fixing and rotating device of the paper pipe for facilitating the cutting of the paper pipe by allowing the paper pipe to be rotated in a fixed state by the paper pipe fixing device in the paper pipe cutting device.

지관은 테이프, 또는 띠형상의 물품을 감아 두기 위한 것으로, 원래 긴 원통형의 지관을 원하는 두께만큼 절단하여 사용하게 된다. 그런데 종래의 지관절단방법은 지관과 지관지지축을 동시에 회전시키면서 역시 회전되는 절단을 위한 도구, 즉 원형의 칼날에 의해 지관이 절단될 수 있도록 하고 있으나, 이는 칼날이 지관을 절단함과 동시에 회전하고 있는 지관지지축에 순간적으로 접하게 되어 칼날의 마모가 매우 심한 폐단을 갖는 것이다.The branch pipe is for winding a tape or a strip-shaped article, and is originally used to cut a long cylindrical branch pipe to a desired thickness. However, the conventional branch cutting method allows the branch to be cut by a tool for cutting, that is, a circular blade, while also rotating the branch and the branch supporting shaft at the same time, but the blade is rotating at the same time as cutting the branch. The instantaneous contact with the branch support shaft has a very severe closure of the blade.

따라서 상기한 방법은 칼날의 손실이 잦고, 자주 칼날을 갈아끼워야 하는 폐단과 또한 지관지지축의 지관과 함께 회전하게 되므로 지관이 흔들리게 되어 절단된 지관의 절단면이 매끄럽지 못하게 되는 폐단을 동시에 갖는 것이다.Therefore, the above method is to have a closed end of frequent cutting of the blade, frequent cutting of the blade, and also the end of the paper tube is rotated together with the branch of the support shaft, the paper tube is shaken, so that the cut surface of the cut paper is not smooth.

이처럼 본 발명은 지관의 절단이 불안정하고, 칼날의 손상이 큰 종래의 방법을 해결하고자 하는 것으로 먼저 지관지지축을 고정시켜 지관만이 회전되도록 하므로써 지관지지축의 회전에 의한 칼날의 손상을 줄일 수 있도록 하였으며, 지관은 균일한 힘과 간격을 갖는 다수개의 걸쇠(clasp)에 의해 안정감있게 클래스핑(clasping)된 상태로 회전축의 회전에 의해 지관지지축 외주면을 회전될 수 있도록 하므로써 지관의 흔들림을 줄여 매끄러운 절단면을 얻을 수 있도록 하는 지관 고정 및 회전장치를 제공하고자 하는 것이다.As described above, the present invention is to solve the conventional method in which the cutting of the branch pipe is unstable and the blade damage is large. First, by fixing the branch support shaft so that only the branch pipe is rotated, the damage of the blade caused by the rotation of the branch support shaft can be reduced. The branch pipe is smoothly clasped by a plurality of clasps with uniform force and spacing, so that the outer surface of the support shaft can be rotated by the rotation of the rotating shaft, thereby reducing the shaking of the branch pipe, thereby providing a smooth cutting surface. To provide a branch pipe fixing and rotating device to obtain.

본 발명을 첨부도면에 의해 더욱 상세히 설명하면 다음과 같다.The present invention will be described in more detail with reference to the accompanying drawings.

본 발명 지관 고정 및 회전장치는 크게 지관(70)을 지지하기 위한 지관지지축(20)과 지관(70)을 고정하기 위한 지관고정장치(50)와 상기 지관고정장치(50)에 의해 지관(70)을 클래스핑하기 위한 이송부(60)와 지관고정장치와 이송부를 회전시키기 위한 회전장치(30)와 상기 이송부(60)를 전후진시키기 위한 이송부구동장치(40)로 구성되어진다.The branch pipe fixing and rotating device of the present invention is large by the branch pipe support shaft 20 for supporting the branch pipe 70 and the branch pipe fixing device 50 for fixing the branch pipe 70 and the branch pipe fixing device 50. Consists of a conveying unit 60 for classing 70, a paper tube fixing device, a rotating device 30 for rotating the conveying unit, and a conveying unit driving device 40 for advancing the conveying unit 60 back and forth.

이를 좀더 상세히 설명하면 지관(70)을 지지하기 위한 지관지지축(20)은 기대(1)와 기대(1)의 상부에 설치된 지지판(2)에 고정된 지관지지축 고정대(10)에 내삽되어 고정된 상태로 지지되어지며, 회전장치(30)는 베어링(32)에 의해 지지되어 지관지지축 고정대(10)의 외주연을 회전될 수 있도록 형성된 회전축(31)과 상기 회전축(31)의 후방에 결합된 풀리(33)와 상기 풀리(33)에 미도시된 모터의 회전력을 전달하기 위한 V벨트(34)로 구성되어진다.To explain this in more detail, the branch support shaft 20 for supporting the branch pipe 70 is interpolated by the branch support shaft holder 10 fixed to the base plate 1 installed on the base 1 and the base 1. It is supported in a fixed state, the rotating device 30 is supported by the bearing 32 is formed to rotate the outer periphery of the support tube support shaft holder 10 and the rear of the rotary shaft 31 It consists of a pulley 33 coupled to the V-belt 34 for transmitting the rotational force of the motor not shown in the pulley 33.

상기 회전축(31)의 선단부에는 지관고정장치(50)가 형성되는데, 상기 지관고정장치(50)는 회전축(31)의 선단부 외주연을 빙둘러 6개 내지 8개 정도 형성된 지지대(51)와, 상기 각각의 지지대(51)에 힌지(52)에 의해 회동자재토록 결합된 걸쇠(53)로 구성되어진다. 상기 걸쇠(53)의 끝단부에는 로울러(54)가 형성되며, 선단부에는 바깥쪽을 향하도록 돌기(55)가 형성된다. 이때 걸쇠(53)은 미도시된 스프링에 의해 항상 축의 중심방향으로 탄발력이 작용한다. 이는 지관(70)이 지관지지축(20)에 끼워졌을 때 걸쇠(53)에 걸리지 않도록 하여 지관(70)의 결합을 용이하도록 하기 위함이다.The branch pipe fixing device 50 is formed at the tip end of the rotating shaft 31, wherein the branch pipe fixing device 50 has a support 51 formed around 6 to 8 round the outer periphery of the tip end of the rotating shaft 31; Each support 51 is composed of a clasp 53 coupled to be rotated by a hinge 52. A roller 54 is formed at the end of the clasp 53, and a protrusion 55 is formed at the front end thereof to face outward. At this time, the latch 53 is always a spring force not acting in the direction of the center of the axis by the not shown. This is to facilitate the coupling of the branch pipe 70 so that the branch pipe 70 is not caught by the latch 53 when the branch pipe 70 is fitted to the branch support shaft 20.

또한 상기 회전축(31)의 외주연에 형성되는 이송부(60)는 선단부 내측으로 경사턱(61)이 형성되고, 외주연 중앙부에는 양쪽이 베어링(62)에 지지되어지는 견인링(63)이 형성되어 있으며, 상기 견인링(63)은 이송부구동장치(40)인 에어실린더(41)의 실린더로드에 결합되어 이송부(60)를 전후진시키게 되는 것이다.In addition, the conveyance part 60 formed on the outer circumference of the rotating shaft 31 is formed with an inclined jaw 61 inside the distal end portion, and a traction ring 63 is formed on both sides of the outer circumferential center portion supported by the bearing 62. The towing ring 63 is coupled to the cylinder rod of the air cylinder 41 which is the transfer unit driving device 40 to advance and move the transfer unit 60.

이때 이송부구동장치(40)의 종류로는 유압실린더 및 기어에 의한 구동장치 등이 있을 수 있으나 본 발명에서는 에어실린더에 의한 구동이 가장 바람직하다.At this time, the transfer unit driving device 40 may include a hydraulic cylinder and a driving device by a gear, but in the present invention, driving by an air cylinder is most preferable.

따라서 상기 이송부(60)에 형성된 경사턱(61)에 의해 지관고정장치(50)의 걸쇠(53)에 형성된 로울러(54)를 눌러주게 되어 지관(70)의 내면이 걸쇠(53)에 의해 클래스핑되어 고정되어지는 것이다. 즉 지관(70)이 지관지지축(20)에 끼워지기 전에는 이송부(60)가 후진되어 있는 상태이므로 로울러(54)가 경사턱(61)의 끝부분, 즉 높은 곳에 위치하므로 스프링의 탄발력에 의해 걸쇠(53)의 돌기(55)가 축의 중심방향으로 향하고 있다가, 지관(70)이 지관지지축(20)에 끼워지게 되면 로울러(54)는 경사턱(61)에 의해 눌려지고 따라서 걸쇠(53)의 돌기(55)는 바깥쪽으로 펼쳐지면서 지관(70)의 끝단부 내면을 클래스핑하게 되는 지관(70)이 고정되는 것이다.Therefore, the roller 54 formed on the clasp 53 of the branch pipe fixing device 50 is pressed by the inclined jaw 61 formed on the conveying unit 60, and the inner surface of the branch pipe 70 is clasped by the clasp 53. It is pinged and fixed. That is, before the branch pipe 70 is fitted to the branch support shaft 20, since the conveying part 60 is in a backward state, the roller 54 is positioned at the end of the inclined jaw 61, that is, at a high position, so When the projection 55 of the clasp 53 is directed toward the center of the shaft, when the branch pipe 70 is fitted to the branch support shaft 20, the roller 54 is pressed by the inclined jaw 61, and thus the clasp 53 is pressed. The projection 55 of the 53 is fixed to the branch pipe 70 which classifies the inner surface of the end of the branch pipe 70 while being extended outward.

이때 지관(70)이 지관지지축(20)에 끼워지는 순간 미도시된 제어장치에 의해 에어실린더(41)가 구동하게 되고, 따라서 이송부(60)도 전진하게 되는데 이때 이송부(60)를 무작정 전진시키게 되면 로울러(54)를 계속 누르게 되어 지관(70)이 파손될 우려가 있으므로 이때 센서의 측정에 의해 적당한 정도의 힘으로 지관(70)을 클래스핑할 수 있을 정도로만 전진시키게 된다.At this time, the air cylinder 41 is driven by the control device (not shown) when the branch pipe 70 is fitted to the branch support shaft 20, and thus the transfer unit 60 is also advanced. In this case, the transfer unit 60 is randomly advanced. If the roller 54 is pressed continuously, the branch pipe 70 may be damaged, and thus, the branch pipe 70 may be advanced only enough to be able to classify the branch pipe 70 with an appropriate level of force by measuring the sensor.

이처럼 본 발명은 지관(70)을 고정 및 회전시키기 위하여 지관고정장치(50)가 형성된 회전축(30)과 지관고정장치(50)를 클래스핑하기 위한 이송부(60)만 회전되는 구조를 갖는 것이다. 물론 이때 이송부(60)의 견인링(63)은 베어링(62)에 의해 지지될 뿐 회전되지는 않는다.As such, the present invention has a structure in which only the conveying part 60 for classifying the rotary shaft 30 and the branch pipe fixing device 50 in which the branch pipe fixing device 50 is formed to fix and rotate the branch pipe 70 is rotated. Of course, the towing ring 63 of the transfer unit 60 is supported by the bearing 62 but is not rotated.

이처럼 본 발명은 종래 한쪽만 고정하던 형태의 지관고정장치에 비해 지관지지축이 고정된 상태에서도 지관고정장치의 걸쇠가 여러방향에서 균일한 힘에 의해 클래스핑하므로 지관이 안정감있게 회전하므로 지관의 절단이 용이하며, 고정된 지관지지축에 의해 지지된 상태로 지관이 회전되는 것이므로 지관의 흔들림이 적어 절단된 지관의 절단면이 매끈하고, 지관절단을 위한 칼날은 지관을 절단하면서 지관지지축의 표면에 닿는다 하더라도 지관지지축이 회전하고 있는 상태보다는 마모가 적어 칼날의 손상을 현저하게 줄일 수 있는 효과를 갖는 것이다.As described above, the present invention cuts the paper pipe because the clasp of the paper pipe fixing device is clad by a uniform force in various directions even when the paper support shaft is fixed in comparison with the paper pipe fixing device of the conventional type. It is easy, because the paper pipe is rotated in a state supported by a fixed paper support shaft, because the shaking of the paper pipe is less, the cut surface of the cut paper pipe is smooth, and the blade for cutting the paper pipe touches the surface of the paper support shaft while cutting the paper pipe. Even if the branch support shaft is less wear than the rotation state has the effect that can significantly reduce the damage of the blade.
