Description

지관 성형기의 지관 절단장치{A PAPER TUBE CUTTER OF PAPER TUBE SPIRAL WINDER}Paper pipe cutting device of paper pipe forming machine {A PAPER TUBE CUTTER OF PAPER TUBE SPIRAL WINDER}

본 발명은 지관(紙管)의 성형 및 절단과정에서 표면지의 손상 방지와 신속 정확한 절단에 의한 지관 품질향상을 도모하기 위한 지관 성형기의 지관 절단장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper pipe cutting device of a paper pipe forming machine for improving the quality of a paper pipe by preventing damage to surface paper during the forming and cutting of a paper pipe and by prompt and accurate cutting.

도 1에서, 통상의 지관 성형기는 비회전체인 장척의 심관(1)과 롤에서 풀려나온 복수의 종이띠(4)를 상기 심관(1)의 겉에 나선상으로 감아 돌려서 지관 성형방향으로 이송하는 지관 성형장치(2), 및 상기 심관(1)의 영역 내에서 성형된 지관(5)을 정해진 길이로 재단하여 규격화하는 지관 절단장치(3)로 구성된다. In Fig. 1, a conventional paper tube forming machine is a paper tube for conveying a long core tube 1, which is a non-rotating body, and a plurality of paper strips 4 released from a roll, spirally wound on the outer surface of the core tube 1, in a paper tube forming direction. And a branch pipe cutting device (3) for cutting and standardizing the branch pipe (5) molded in the region of the core pipe (1) to a predetermined length.

지관의 원자재인 종이띠의 이면에는 심관에 감기기 직전에 접착제가 도포되고, 지관 성형장치는 한 쌍의 회전식 드럼이 심관을 사이에 두고 대칭되게 설치된 상태에서 양쪽 드럼 간에 평벨트를 8자상으로 둘러 종이띠를 나선상으로 감아 붙여 지관으로 성형한다. 상기 드럼은 모터에 의해 회전하는 구동 드럼이다.Adhesive is applied to the back of the paper strip, which is the raw material of the paper tube, just before being wound on the core pipe, and the paper pipe forming device is formed by enclosing the flat belt between two drums in a shape of eight pieces with a pair of rotary drums symmetrically installed between the core pipes. The strip is wound spirally and molded into a branch pipe. The drum is a drive drum that is rotated by a motor.

지관의 두께는 종이띠의 수에 따라 결정되며, 후미에서 공급되는 종이띠는 지관의 표면지다. 표면지는 무늬지 색상지 비닐지 등이며, 지관의 미관 및 상품성을 높이기 위해서 지관의 표면 마무리, 즉 마감재로 사용된다. The thickness of the paper tube is determined by the number of paper strips, and the paper strip supplied from the rear is the surface of the paper tube. The surface paper is pattern paper, color paper, vinyl paper, and the like, and is used as the surface finish of the paper pipe, that is, the finishing material, in order to enhance the aesthetics and commerciality of the paper pipe.

도 2에서, 지관 절단장치(3)는 성형 후 이송되는 지관(5)과 동일 방향, 동일한 속도로 궤적(c)을 선회하면서 지관을 일정한 길이로 절단하는 것으로서, 지관과 동일 방향 및 동일한 속도로 지관 절단장치를 궤도 선회시키는 종방향 이동수단(6)과, 상기 종방향 이동수단(6)이 지관을 따라 이동할 때 회전칼을 횡방향으로 이동시켜 지관을 절단토록 하는 횡방향 이동수단(7), 도 2 및 도 3과 같이 회전칼이 지관을 절단할 때 지관을 받쳐주는 지관 받침수단(8)으로 구성된다.In FIG. 2, the branch pipe cutting device 3 cuts the branch pipe in a constant length while turning the trajectory c in the same direction and at the same speed as the branch pipe 5 which is conveyed after molding, in the same direction and at the same speed as the branch pipe. Longitudinal moving means 6 for orbiting the paper tube cutting device, and transverse moving means 7 for moving the rotary knife laterally when the longitudinal moving means 6 moves along the paper pipe to cut the paper pipe. 2 and 3, the rotary knife is composed of a paper supporting means (8) for supporting the paper pipe when cutting the paper pipe.

장척의 심관에 복수의 종이띠가 겹쳐지게 감겨 성형되면서 이송되는 지관은 비록 심관에 의지해 이송되더라도 지관이 관경에 비해 워낙 장척이기 때문에 심관의 말단으로 갈수록 지관이 떨리고 출렁이는 경향이 있으며, 이를 방치하면 지관이 삐딱하게 절단되어 불량화 된다.The paper tubes that are transported by forming a plurality of paper bands overlapped and molded on the long core pipe are tended to shake and sway toward the end of the core pipe because the paper pipe is so long compared to the diameter, even though it is transported by the core pipe. If left unattended, the paper pipe will be severely cut and deteriorated.

상기 지관 받침수단은 이 점을 의식한 필수 요소로서, 회전칼의 대향 방향에 2개 1조로 설치된 비회전식 환봉이며, 회전칼과 받침수단의 배열상태에 따라 종형과 횡형으로 구분된다.The branch support means is an essential element conscious of this point, and is a non-rotating round rod installed in two pairs in the opposite direction of the rotary knife, and is divided into a vertical type and a horizontal type according to the arrangement state of the rotary knife and the supporting means.

유형을 불문하고 종래의 지관 받침수단은 환봉과의 마찰로 인하여 지관의 표면지가 손상되기 쉽고, 이로 인한 불량률도 높은 것이 문제다. 성형과 동시에 회전하면서 심관의 말단을 향해 축 방향으로 이송되는 지관에 회전칼이 다가가 절단하는 과정에서 미처 건조되지 아니한 지관의 피절단부가 회전칼에 눌려 받침대에 접촉되는 순간 일시적으로 정지되는 정체현상이 발생할 때 표면지(S)가 찢어지거나 일그러지기 십상이고, 이런 상태에서 지관이 절단되다 보니 불량이 발생하고 지관의 정상적인 회전 이송에도 지장을 초래하기 때문이다. Regardless of the type, the conventional paper tube supporting means is susceptible to damage of the surface paper of the paper tubes due to friction with the round bar, and thus a high defect rate. Stagnation phenomenon when the cut part of the paper pipe, which is not dried, is temporarily stopped when it is pressed by the rotary knife while the rotary knife approaches and cuts the paper pipe that is axially transferred toward the end of the core pipe. This occurs because the surface paper (S) is likely to be torn or distorted, and the paper tube is cut in this state, so that a defect occurs and causes trouble even in the normal rotational transfer of the paper tube.

받침 환봉을 회전식 롤로 대체하더라도 순간적인 미세한 접촉저항은 불가피하기 때문에 표면지(S)의 손상 정도에 차이는 있을지언정 불량 발생은 막을 도리가 없다. 표면지가 마르지 않은 상태이므로 약간의 외부 접촉이나 저항력을 받으면 쉽게 손상되며, 손상된 지관은 불량처리된다. Even if the supporting round bar is replaced by a rotary roll, instantaneous minute contact resistance is inevitable, so there may be a difference in the degree of damage of the surface paper S, but there is no way to prevent the occurrence of defects. Since the surface paper is not dry, it is easily damaged by some external contact or resistance, and the damaged paper pipe is badly treated.

본 발명은 지관 성형기의 절단장치를 형성함에 있어, 종래 사용되던 받침대를 생략하면서도 지관 표면지의 손상 방지와 신속 정확한 절단에 의한 지관 품질향상 및 생산성 향상에 목적을 둔 지관 성형기의 지관 절단장치를 제공하려는 것이다.
The present invention is to provide a paper cutting machine of the paper pipe forming machine aimed at improving the quality of the paper pipe and improved productivity by preventing the damage of the paper surface of the paper surface and the rapid and accurate cutting in forming the cutting device of the paper pipe forming machine, while omitting the pedestal used in the prior art. will be.

이 과제를 달성하기 위하여 본 발명은 성형장치에 의해서 성형 이송되는 지관과, 서버모터에 의해서 지관의 이동방향을 따라서 진퇴 작동하는 슬라이더와, 상기 슬라이더의 상면에 지관을 중심으로 마주보게 설치한 2조의 절단부와, 상기 절단부의 브래킷에 설치한 한 쌍의 회전칼과, 상기 슬라이더에 탑재된 절단부를 횡방향으로 진퇴시키는 왕복동수단으로 이루어지며, 지관을 중심으로 하여 그 양쪽에 설치한 4개의 회전칼이 동시에 지관 외면에 4점 접지 작용으로 파고들어 절단작동과 받침작용을 동시에 수행토록 한 것을 특징으로 한 것이다.
In order to achieve the above object, the present invention provides two sets of paper pipes formed by a molding apparatus, a slider moving forward and backward along a moving direction of the paper pipes by a server motor, and two sets of the upper surfaces of the sliders facing each other. It consists of a cutting part, a pair of rotary knives installed on the bracket of the cutting part, and reciprocating means for advancing the cutting part mounted on the slider in the lateral direction, and four rotary knives provided on both sides of the branch pipe. At the same time, the outer surface of the branch pipe was dug into four points of grounding action, so that the cutting operation and the supporting action were performed simultaneously.

본 발명은 지관을 절단할 때 4개의 회전칼이 동시에 진퇴작동하게 되고, 지관을 중심으로 하여 양쪽에서 4개의 회전칼이 지관의 외면에 4점 접촉방식으로 동시에 파고들어 절단하므로 단일 회전칼에 의존했던 종래의 지관 절단장치에 비해 절단작업이 신속하다.In the present invention, four rotary knives advance and retract at the same time when cutting a paper tube, and four rotary knives on both sides of the paper tube are simultaneously cut into four points of contact with the outer surface of the paper tube and rely on a single rotary knife. The cutting operation is faster than the conventional paper pipe cutting device.

또, 4개의 회전칼이 지관 외면에 포위하듯이 4점 방식으로 접속되어 받쳐주기 때문에 절단작용 수행하면서도 지관을 받쳐주는 기능도 수행하며, 지관을 균등하게 받쳐주면서 절단하기 때문에 지관이 바르게 절단되고 절단면이 깨끗하며, 특히 종래 사용되던 받침대를 생략하면서도 표면지가 전혀 훼손되지 않게 지관을 절단할 수 있다.
In addition, since the four rotary knives are connected in a four-point manner as if they are surrounded on the outer surface of the branch, the cutting operation is carried out while supporting the branch, while the branch is cut evenly while supporting the branch. This clean, and in particular, it is possible to cut the paper tube so as not to damage the surface paper at all while omitting the conventionally used pedestal.

도 4에서, 본 발명에 의한 지관 절단장치는 지관(5)과 동일방향, 동일속도로 이동하는 슬라이더(11) 위에 동형의 제1 절단부(10)와 제2 절단부(20)가 마주보게 설치되는 구조로서, 슬라이더(11)를 지관(5) 하방에 설치하였기 때문에 양쪽 절단부(10)(20) 사이에 지관(5)이 위치하도록 구성한 것이다.In Figure 4, the branch pipe cutting device according to the present invention is provided with the first cut portion 10 and the second cut portion 20 of the same type on the slider 11 moving in the same direction, the same speed as the branch pipe (5). As the structure, since the slider 11 was provided below the branch pipe 5, it is comprised so that the branch pipe 5 may be located between both cut-out parts 10 and 20. As shown in FIG.

더욱 자세하게는, 지관(5)을 중심으로 하여 그 양쪽에 제1 절단부(10)와 제2 절단부(20)가 대향되게 설치되어 지관(5)을 향하여 동시에 전진(절단)하거나 후진(복귀)하는 작동을 수행한다.More specifically, the first cutout portion 10 and the second cutout portion 20 are disposed on both sides of the branch pipe 5 so as to face each other so as to move forward (cut) or backward (return) toward the branch pipe 5 at the same time. Perform the operation.

상기 슬라이더(11)는 서버모터와 나사축(M)에 의해서 지관과 동일방향, 동일속도로 안내레일(R)을 따라서 움직이며,지관의 절단방향을 향하여 지관과 등속으로 이동하다가 소정의 위치에서 양쪽 절단부에 의해서 지관의 절단작동이 이루어진다. The slider 11 moves along the guide rail R at the same direction and at the same speed as the branch pipe by the server motor and the screw shaft M, and moves at a constant speed with the branch pipe in the direction of cutting of the branch pipe. The cutting operation of the branch pipe is performed by both cutting parts.

상기 슬라이더(11) 위에 탑재된 제1, 제2 절단부(10)(20)는 각각 하단에 캐리어(12)를 가지고 있으며, 캐리어(12)는 레일(K)에 탑재된 상태로 실린더를 이용한 왕복동수단(16)에 의해서 정해진 행정 범위 내에서 횡방향으로 왕복 운동한다.      The first and second cut portions 10 and 20 mounted on the slider 11 each have a carrier 12 at a lower end thereof, and the carrier 12 is mounted on the rail K in a reciprocating motion using a cylinder. It reciprocates in the transverse direction within the stroke range defined by the means 16.

상기 캐리어(12)의 상부에 탑재된 커터대(13)에는 브래킷(21)이 장착되고, 상기 브래킷(21)의 선단에는 한 쌍의 회전칼(13a,13b)이 일정한 벌림간격을 갖도록 상하로 설치되어 있다. A bracket 21 is mounted on the cutter stand 13 mounted on the upper portion of the carrier 12, and a pair of rotary knives 13a and 13b is vertically spaced up and down at the tip of the bracket 21. It is installed.

이들 회전칼(13a,13b)은 높이차를 두고 종렬로 설치되며, 도시예에서는 상부 회전칼(13a)이 모터(14)에 의해 구동하는 구동측이고, 하부 회전칼(13b)은 지관(5)을 매개로 하여 제자리 회전하는 피동측이다.These rotary knives 13a and 13b are arranged vertically with a height difference. In the illustrated example, the upper rotary knife 13a is a drive side driven by the motor 14, and the lower rotary knife 13b is a driven side which rotates in place via the branch pipe 5.

양쪽 절단부의 회전칼(13a,13b)은 횡방향 왕복동수단(16)에 의해 4점 방식으로 지관에 동시 외접되어 절단하고 복귀하게 되므로 종래의 단식 회전칼에 비해 지관 절단 소요시간이 짧다. 그래서 지관을 신속하게 절단할 수 있다. The rotary knives 13a and 13b of both cutting parts are cut out and returned to the paper tubes simultaneously in the four-point manner by the transverse reciprocating means 16, and thus the time required for cutting the paper tubes is shorter than that of the conventional single rotary knife. Therefore, the branch pipe can be cut quickly.

지관을 절단할 때 4개의 회전칼은 대각방향에서 지관에 동시적으로 접촉돼 받쳐주면서 회전하므로 종래의 비회전식 환봉제 받침수단에 비해 지관에 대한 접촉저항이 극미하다. 이에 따라 지관의 피절단부가 눌려 일시적으로 정체되는 현상이 사라져 절단 품질이 향상되고, 지관 절단소요시간의 단축도 가능해진다. When cutting the paper tube, the four rotary knives are rotated while simultaneously supporting and supporting the paper tube in the diagonal direction, so that the contact resistance to the paper tube is minimal compared to the conventional non-rotating round sewing support means. As a result, the phenomenon in which the cut portion of the branch pipe is pressed and temporarily stagnated disappears, thereby improving cutting quality and shortening the branch cutting time.

도 6과 같이 양쪽 4개의 회전칼이 동시에 전진하여 지관을 절단할 때, 심관의 말단으로 갈수록 떨리기 십상인 지관의 외면에 먼저 가닿는 회전칼과 찰나적이지만 시차를 두고 나머지 회전칼이 가닿을 수도 있다.When the four rotary knives are simultaneously advanced to cut the branch pipe as shown in FIG. 6, the rotary knife first touches the outer surface of the branch pipe which is apt to tremble toward the end of the core tube. have.

이 경우, 먼저 가닿는 회전칼에 의하여 지관이 나중에 가닿을 회전칼 쪽으로 치우칠 수 있고, 나머지 회전칼이 마저 가닿는 순간 그 접촉 저항으로 말미암아 양측 회전칼 사이의 지관 부분이 순간적으로 찌그러질 가능성도 있다. 이를 방임하면 지관이 삐딱하게 절단되어 품질이 떨어진다. In this case, the branch pipe may be biased toward the rotary knife to be touched later by the rotary knife that touches first, and there is a possibility that the branch pipe portion between both rotary knives may be momentarily distorted due to the contact resistance at the moment when the remaining rotary knife touches even. . If it is left to stand, the paper pipe is cut tightly and the quality is poor.

또, 4개의 회전칼이 지관에 외접할 때 접촉저항을 완화하면 더욱 안정되고 안전하게 지관을 받치면서 깔끔하고 신속 정확하게 지관을 절단할 수 있을 것이다.In addition, if four rotary knives are externally contacted to the paper tube, the contact resistance will be relaxed, and the paper tube can be cut neatly and accurately while supporting the paper tube more stably and safely.

이런 점을 고려하여, 도 7과 같이, 한 쌍의 회전칼이 설치된 브래킷(21)의 후단부를 커터대(13) 상부에 핀(22)으로 설치하되, 브래킷(21)의 하단에 유동간극(W)을 형성하고 핀(22)을 중심축으로 하여 브래킷(21)의 선단이 상하로 유동이 용이하게 설치함으로써 절단부에 유동성 관절(25)을 형성하였다.In consideration of this point, as shown in FIG. 7, the rear end of the bracket 21 in which the pair of rotary knives is installed is installed as the pin 22 on the upper portion of the cutter stand 13, but the flow gap ( W) was formed and the flowable joint 25 was formed in the cut part by easily installing the tip of the bracket 21 up and down with the pin 22 as the center axis.

또한 브래킷(21)의 하단에는 완충스프링(27)을 고여서 선단이 들려지는 탄성을 갖도록 구성하였으며, 이렇게 절단부에 유동성 관절(25)을 형성함으로써 지관에 외접할 때 회전칼 사이의 접촉 시차를 최소화해 동시적 접촉성을 높인다. In addition, the lower end of the bracket 21 is configured to hold the buffer spring 27 so as to have the elasticity of the tip is lifted, by forming a flowable joint 25 in the cut portion in this way to minimize the contact parallax between the rotary knife when external to the branch pipe Solution Improves simultaneous contact.

또한 회전하면서 이송되는 지관의 외면에 먼저 가닿은 회전칼의 접촉저항에 의하여 관절은 핀을 중심으로 선회하고, 관절의 각 운동량만큼 나머지 회전칼이 같은 방향으로 선회하여 지관에 접지되는 선,후 회전칼 간에 존재할 접촉 시차가 무시될 정도로 동시적인 접지가 부드럽게 이뤄진다. In addition, the joint is pivoted about the pin by the contact resistance of the rotary knife first touching the outer surface of the paper tube being transported while rotating, and the remaining rotary knife is rotated in the same direction by the angular momentum of the joint to be grounded to the branch pipe. Simultaneous grounding is smooth enough to neglect the contact parallax present between the knives.

양쪽 4개의 회전칼이 지관에 동시적으로 외접되어 절단할 때 제1 지관 절단부(10)과 제2 지관 절단부(20)의 하측 회전칼은 상대편 절단부가 지관을 절단할 때 대각선방향으로 받쳐주는 받침 역할도 수행한다. The lower rotary knife of the first branch cut section 10 and the second branch cut section 20 when the two rotary knives are cut externally simultaneously to the branch pipe is supported by a diagonal direction when the opposite cut section cuts the branch pipe. It also plays a role.

회전칼들의 상기와 같은 상호 받침 역할은 결국 절단 시 종래의 지관 절단장치에 보다도 지관의 자세가 더욱 안정되므로 절단면이 깨끗한 양호한 품질의 지관을 얻을 수 있다.The role of the mutual support of the rotary knives as a result of the posture of the paper pipe is more stable than the conventional paper pipe cutting device at the time of cutting, it is possible to obtain a good quality paper pipe with a clean cut surface.

4개의 회전칼에 의한 4점 동시 절단이 가능한 제1 및 제2 절단부(10,20)는 종래의 단수 회전칼 - 복수 받침 환봉형 지관 절단부에 비해 지관 절단작업능률이 단순한 수치상으로 4배가량 크게 증가한다. The first and second cutting parts 10 and 20, which can simultaneously cut four points by four rotary knives, are four times larger than the conventional single rotary knives-multiple supporting round bar type paper pipe cutting parts, which are simpler in terms of paper cutting efficiency. Increases.

유동성 관절에 설치한 완충스프링(27)은 절단부의 자체중량으로 선단이 숙여지는 것을 탄력적으로 받쳐주며, 지관에 시차를 두고 접촉되는 회전칼로 전달되는 진동을 흡수하여 바른 자세로 동시적으로 지관에 외접할 수 있고, 지관이 절단되면 그로부터 받던 압력이 사라져 회전칼을 포함한 관절을 탄력적으로 원위치 복귀시킨다.
The shock absorbing spring (27) installed in the fluid joint elastically supports the tip leaned by the weight of the cutting part, absorbs the vibration transmitted to the rotary knife contacted with the parallax on the branch pipe, and simultaneously circumscribes the branch pipe in a correct posture. When the branch pipe is cut, the pressure received therefrom disappears and the joint including the rotary knife is elastically returned to its original position.
