The punching machine can easily cut the base paper board by mounting the elastic restoration device at the edge of the bland of the punching die in order to concentrate stress on the base paper board by being hit by an operating member at the edge of the blank. In addition, the punching machine can clearly cut a joint part using elastic resistance of the operating member while the cutting blade continues to move. Finally, the elastic restoration device can be flexibly mounted to be used in manufacturing paper boxes with various types and sizes by being mounted at a certain point where a blank is formed.

Description

탄성 복원구가 구비된 종이박스 제조장치의 펀칭기구{PUNCHING-CUTTER FOR MAKING PAPER BOX HAVING ELASTIC RESTORATON DEVICE}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching mechanism for a paper box manufacturing apparatus having an elastic restoring member,

본 발명은 종이박스 제조장치에 있어서 펀칭기구의 탄성복원구에 관한 것으로, 보다 상세하게는 판지의 절단부분이 이어짐이 없이 깨끗하게 제거되도록 펀칭다이에 장착하는 탄성복원구에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an elastic restoring member of a punching mechanism in a paper box manufacturing apparatus, and more particularly, to an elastic restoring member which is mounted on a punching die so that a cut portion of the paper is not removed.

물건을 수납 보관하거나 상품을 포장 유통시키기 위하여 다양한 종류, 크기를 가지는 종이박스가 널리 이용되고 있다. 통상, 이러한 종이박스는 모재판지에 상품내용을 인쇄하는 인쇄공정, 종이박스를 성형 조립하기 위한 모재판지의 펀칭공정, 그리고 펀칭된 모재판지의 붙임ㅇ조립공정을 통해서 제조되고 있다.
Various types and sizes of paper boxes are widely used to store and store goods or to distribute products. Generally, such a paper box is manufactured through a printing process for printing the contents of a product on a base material cardboard, a punching process for a base material cardboard for molding and assembling a paper box, and an assembling process for attaching a punched base material cardboard.

종래의 일반적인 펀칭공정은, 모재판지를 절단하기 위한 절단칼날이 배치 장착되어 일정한 스트로크로 왕복운동하는 펀칭보드와, 펀칭보드의 왕복운동시 절단칼날이 통과하는 블랭크 영역이 마련되고 절단되는 모재판지를 받히고 있는 펀칭다이로 구성된 펀칭설비를 이용하고 있다.
A conventional general punching process includes a punching board in which a cutting blade for cutting a base material cardboard is disposed and reciprocating in a predetermined stroke, a blank material board in which a blank area through which a cutting blade passes is formed during the reciprocating motion of the punching board, And a punching device composed of a punching die is used.

그러나, 종래의 펀칭공정에서는 모재판지의 중앙 영역에 손잡이 등의 구멍을 만들기 위하여 펀칭하는 경우 가장자리가 떨어져 나가지 않고 이어져 있는 현상이 발생되고 있다. 이러한 이어짐이 발생되는 주요 원인은 펀칭 보드의 절단칼날 위치와 절단칼날이 통과하는 펀칭 다이의 블랭크 가장자리 거리가 어긋나 있거나 너무 크게 이격되어 있어 절단칼날의 전단응력이 모재판지의 절단위치에 집중하지 못하고 분산 흡수되기 때문이다.
However, in the conventional punching process, when the punching is performed in order to make a hole of a handle or the like in the central area of the base material cardboard, a phenomenon occurs that the edge does not fall off. The main causes of the overrun are that the cutting edge position of the punching board and the blank edge distance of the punching die through which the cutting blade passes are too far or too far away so that the shearing stress of the cutting blade does not concentrate at the cutting position of the base material sheet, It is absorbed.

이 경우 떨어져 나가지 않고 이어져 있는 부분을 제거하기 위하여 별도의 마무리 제거작업을 실시해야 하기 때문에 생산성이 떨어지고 제조원가가 상승하는 문제가 있다.
In this case, since separate finishing removal work must be performed in order to remove the continuous portion without falling off, the productivity is lowered and the manufacturing cost is increased.

또한, 다양한 종류와 크기를 가지는 종이박스마다 전단응력이 집중되는 블랭크를 갖는 맞춤 펀칭 다이를 준비하는 데에는 많은 비용이 소요되는 문제점이 있다.
In addition, there is a problem in that it takes a lot of cost to prepare a custom punching die having a blank in which shear stress concentrates for each paper box having various kinds and sizes.

본 발명은 상술한 바와 같은, 종래의 문제점을 해결하기 위한 것으로, 펀칭공정에서 절단부분의 이어짐이 발생되지 않고, 다양한 종류와 크기의 종이박스 펀칭공정에 적용할 수 있는 기구를 제공하는 것을 목적으로 한다.
SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems as described above, and it is an object of the present invention to provide a mechanism that can be applied to a paper box punching process of various kinds and sizes without leading to the cutting portion in the punching process do.

상기한 발명의 목적은, 모재판지를 절단하는 절단칼날이 마련 배치되고, 왕복운동 수단에 장착 결합된 펀칭 보드와, 펀칭 보드에 대향하여 설치되며, 펀칭 보드의 절단칼날에 대응하는 위치에 블랭크가 형성된 펀칭 다이와, 펀칭 다이의 블랭크 영역의 가장자리에 설치되는 탄성복원구에 의해 달성된다.
It is an object of the present invention to provide a punching board which is provided with a cutting blade for cutting a base material paperboard and which is mounted on and bonded to a reciprocating means and is provided so as to face the punching board, And a resilient restoring tool provided at the edge of the blank area of the punching die.

그리고, 탄성복원구는 다양한 종류와 크기를 가지는 종이박스 제조에 적용하기 위하여 펀칭 보드의 블랭크 영역의 가장자리에 결합 고정되는 몸체와, 몸체의 상단부 한쪽 단부영역의 함몰공간과, 함몰공간의 양측에 형성되어 각각 축지지공을 가지는 지지벽체와, 함몰공간에 수용되고 펀칭 보드의 왕복운동시에 절단칼날과 접촉하여 변위 후 복원되는 가동부재와, 가동부재에 삽입되는 탄성부재와, 가동부재와 상기 탄성부재와 상기 축지지공에 삽입되어 상호 축결합시키는 지지축으로 구성되는 것이 바람직하다.
The elastic restoring portion is formed on both sides of the recessed space of one end region of the upper end of the body and a recessed space formed on both sides of the recessed space so as to be engaged with the edge of the blank region of the punching board for application to the manufacture of paper boxes having various kinds and sizes A movable member accommodated in the recessed space and brought into contact with the cutting blade in the reciprocating motion of the punching board to be restored after being displaced; an elastic member inserted into the movable member; And a support shaft inserted into the shaft hole and mutually axially coupled.

또한, 탄성복원기구에 조립되는 가동부재는 절단칼날의 초기 접촉시에 큰 응력을 받으면서 변위한 다음 원래의 위치로 복원할 수 있는 구조를 가질 수 있도록, 가동부재는 함몰부에 삽입되는 원형 측단부를 가지는 봉상체로서, 봉상체의 상부 및 하부 접선방향으로 연장되어 형성된 돌출부와, 원형 측단부의 중심에 형성된 축공과, 돌출부 반대측 중앙부가 함몰되어 탄성부재를 수용하는 탄성부재 수용부가 형성된 것이 바람직하다.
Further, the movable member, which is assembled to the elastic restoring mechanism, can have a structure capable of restoring to the original position after being displaced while receiving a great stress at the initial contact of the cutting blade, It is preferable that a protruding portion formed to extend in the tangential direction of the upper and lower portions of the bar body and a shaft hole formed in the center of the circular side end portion and an elastic member receiving portion accommodating the elastic member by being depressed at the central portion opposite to the protruding portion are formed .

이에 의하여, 본 발명의 탄성복원구를 가지는 종이박스 제조장치의 펀칭기구는, 펀칭다이의 블랭크 영역의 가장자리에 탄성복원구를 장착함으로써, 펀칭보드에 장착된 절단칼날이 모재판지를 지나 블랭크 영역의 가장자리를 통과할 때, 블랭크 영역의 가장자리에 가동부재의 받침으로 인하여 모재판지의 절단부위에 전단응력이 집중되어 절단이 용이하게 이뤄진다. 또한, 절단칼날이 계속 진행하면서 모재판지의 절단부위가 가동부재의 탄성저항을 받기 때문에, 끊어지지 않고 이어져 있는 부분이 더욱 확실하게 끊어져 나간다.
Thus, the punching mechanism of the paper box manufacturing apparatus having the elastic restoring portion of the present invention is characterized in that the elastic restoring tool is mounted at the edge of the blank area of the punching die, so that the cutting blade mounted on the punching board passes through the base material paperboard Shear stress is concentrated on the cut part of the base material sheet due to the backing of the movable member at the edge of the blank area when passing the edge, so that the cutting can be easily performed. In addition, since the cutting edge of the base material sheet receives the elastic resistance of the movable member while the cutting blade continues, the continuous portion without breaking is more reliably broken.

따라서, 이어진 부분을 제거하기 위한 별도의 작업이 생략되어 생산성이 향상되고 원가가 절감된다.
Therefore, a separate operation for eliminating the following portion is omitted, and the productivity is improved and the cost is reduced.

또한, 탄성복원구는 블랭크가 형성된 임의의 장소에 장착할 수 있기 때문에 다양한 종류와 크기를 가지는 종이박스 제조에 융통성있게 장착하여 사용할 수 있다.
In addition, since the elastic restoration can be mounted at an arbitrary place where the blank is formed, it can be flexibly attached to various types and sizes of paper boxes.
