본 고안의 다른 목적은 소동력으로 효과적인 절단을 행할 수 있으며, 크기가 비교적 소형으로 되어 간결한 절단장치를 제공함에 있다.Another object of the present invention is to provide an effective cutting with a small force, and to provide a compact cutting device is relatively small in size.

본 고안은 각개 칼날 고정구의 양단부를 편심축으로 각각 지지하여 칼날 고정구에 부착되어 작동하는 한쌍의 대향설치된 절단칼날이 실질적인 원운동을 하도록 구성하고 전기한 각각의 칼날 고정구가 편심축에 지지되어 중심선이 일치된 상태에서 절단 칼날의 대칭운동을 정확하게 이행하도록 칼날 고정구의 수직관통공에 두개의 수직 가이드바를 활동가능하게 삽통하여 칼날 고정구가 수직 가이드바에 의해 안내되도록 이루어져 있다.The present invention supports a pair of opposite cutting blades which are attached to the blade fixtures to support both ends of each blade fixture with an eccentric shaft. The blade fixture is guided by the vertical guide bar by activating the two vertical guide bars into the vertical through-holes of the blade fixture in order to accurately perform the symmetrical movement of the cutting blade in the matched state.

이하 본 고안은 첨부된 도면에 따라 실시예로서 설명한다.Hereinafter, the present invention will be described as an embodiment according to the accompanying drawings.

제1도에 있어서 언코일러(uncoile)(1)에 감겨져 있는 띠 강판(2)은 먼저 교정로울러(3)를 지나서 실질적인 평판으로 고정된 다음에 측정로울러(4)를 통과하여 평판의 송출속도에 의한 송출길이가 검출된다.In FIG. 1, the strip steel sheet 2 wound around the uncoile 1 is first fixed to a substantially flat plate through the calibration roller 3 and then through the measuring roller 4 to the feed rate of the flat plate. Delivery length is detected.

검출길이가 소정의 절단길이에 상당할때 측정로울러(4)에 직렬 연결되어 있는 제어기가 전동기를 구동하여 절단기(5)를 작동시키고 이것에 의해 주행하는 띠강판(2)의 절단지점이 정확하게 절단되는 것이다.When the detection length corresponds to the predetermined cutting length, the controller connected in series to the measuring roller 4 drives the motor to operate the cutting machine 5 and thereby cuts the cutting point of the strip steel plate 2 that travels. Will be.

그리고 절단된 강판(6)은 콘베이어(7)에 의해 적치대(8)위로 순차 반송되어진다.And the cut steel plate 6 is conveyed on the mounting base 8 by the conveyor 7 one by one.

절단기(5)는 제2도 내지 제4도의 표시와 같이 교정로울러(3)에서 송출되는 띠강판(2)이 중심부를 통과하도록 한 구조로 조립된 프레임(10)으로 구성되어 있다.The cutter 5 is composed of a frame 10 assembled in a structure such that the band steel plate 2 sent out from the straightening roller 3 passes through the center portion as shown in FIGS. 2 to 4.

프레임(10)은 측벽(18)에 의해 내부에 기어박스를 형성하고 있으며, 측벽(18)에는 저어널 베어링(17)(17')을 개재한 두 쌍의 횡축(16)(16')이 각각 상하로 대향 설치되어 있고, 각각의 횡축(16)(16')에 부착된 기어(20)(20')는 상호 치차연결되어 있다.The frame 10 has a gearbox formed therein by sidewalls 18, and two pairs of transverse shafts 16, 16 'via journal bearings 17, 17' are formed on the sidewall 18. The gears 20 and 20 'attached to each of the transverse shafts 16 and 16' are geared up to face each other.

프레임(10)의 바닥 부근에서 횡방향으로 연장되어, 각 측벽(18)에 관통설치된 구동축(22)은 한쌍의 저어널 베어링(21)으로 축지지되어 있고, 구동축(22)에 부착된 기어(23)는 하부의 횡축(16')에 부착된 기어(20')와 상호 치차연결되어 있으며, 구동축(22)의 한끝은 커플링(24)을 개재하여 전동기(25)로 연결되어 있다.A drive shaft 22 extending laterally near the bottom of the frame 10 and penetrated to each side wall 18 is axially supported by a pair of journal bearings 21, and a gear (attached to the drive shaft 22). 23 is tooth-connected with the gear 20 'attached to the lower horizontal axis 16', and one end of the drive shaft 22 is connected to the electric motor 25 via the coupling 24.

또한 횡축(16)(16')의 내단부는 측벽(18)의 내면보다 돌출되어 있다.In addition, the inner ends of the horizontal axes 16 and 16 'protrude from the inner surface of the side walls 18.

각각 베어링(27)(27')을 개재하여 편심축(15)(15')에 수평지지된 칼날 고정구(11)(11')는 상하로 배열되어서 횡축(16)(16')의 내단 돌출부에 편심연결되어 편심률 R로서 각각 회전된다.The blade fixtures 11 and 11 'horizontally supported on the eccentric shafts 15 and 15' via the bearings 27 and 27 'are arranged vertically so that the inner end protrusions of the transverse shafts 16 and 16' are arranged. Eccentrically connected to and rotated as the eccentricity rate R, respectively.

즉, 구동축(22)의 회전에 의해 구동력은 기어(23)(20')(20)를 경유하여 횡측(16)(16')에 전달되고, 그 결과 칼날고정구(11)를 지지하는 편심축(15)과 칼날고정구(11')를 지지하는 편심축(15')은 상호 반대방향으로 동시에 회전된다.That is, the driving force is transmitted to the transverse side 16 and 16 'via the gears 23, 20' and 20 by the rotation of the drive shaft 22, and as a result, the eccentric shaft which supports the blade fixture 11 as a result. 15 and the eccentric shaft 15 'supporting the blade fixture 11' are simultaneously rotated in opposite directions.

절단칼날(26)은 상부 칼날고정구(11) 하단에 임의로 절단각도를 조절할 수 있게 고정부착하고, 또 하나의 절단칼날(26')도 하부 칼날고정구(11')의 상단에 부착되어 상부 절단칼날(26)과 대향 설치된다.The cutting blade 26 is fixedly attached to the lower edge of the upper blade fixture 11 so as to adjust the cutting angle arbitrarily, and another cutting blade 26 'is also attached to the upper edge of the lower blade fixture 11' to the upper cutting blade. It is opposite to 26.

프레임(10)의 내부 상방에는 단면이 L형상이고 2개를 1조로 하여 대향 설치된 주행레일(14)이 적당한 간격을 두고 평행으로 고정 서치되어 있으며, 각 주행레일(14) 사이에는 단면이 장방형으로 된 수직 가이드바(12)가 그 상단에 고정 설치된 두개의 축에 지지된 로울러(13)를 개재하여 현수되어 있다.In the upper part of the frame 10, the cross section is L-shaped, and two running rails 14 are fixedly searched in parallel at regular intervals, and the cross sections are rectangular in shape between the running rails 14, respectively. The vertical guide bar 12 is suspended through a roller 13 supported on two shafts fixed at the upper end thereof.

로울러(13)는 상부축과 하부축에 각각 지지되어 주행레일(14)의 상하 수평단면상에서 전동하게 되므로 각각의 수직가이드바(12)는 주행레일(14)을 타고 활동할 수 있게 된다.The rollers 13 are supported on the upper and lower shafts, respectively, so that the rollers 13 are electrically driven on the upper and lower horizontal cross sections of the traveling rails 14, so that each vertical guide bar 12 may be operated by the driving rails 14.

칼날고정구(11)(11')의 양단에는 각각 수직가이드바(12)가 삽통되는 수직관통공(19)(19')이 천설되어 있으며, 칼날고정구(11)(11')는 수직 가이드바(12)를 타고 수직 중심선이 일치된 상태에서 원활하게 수직운동을 행하게 되고, 편심축(15)은 수직 가이드바(12)에 의해 수평중심선이 일치된 상태로 회전하게 된다.Vertical through-holes 19 and 19 'through which vertical guide bars 12 are inserted are disposed at both ends of the blade fixtures 11 and 11', respectively, and the blade fixtures 11 and 11 'are vertical guide bars. The vertical movement is smoothly performed in the state where the vertical center line is matched with (12), and the eccentric shaft 15 is rotated in the state where the horizontal center line is matched by the vertical guide bar 12.

이러한 배치에 의해 절단칼날(26)(26')의 상호 대칭지점은 확실하게 보전되어 제4도의 표시와 같이 띠 강판을 절단하게 되며, 절단칼날은 띠강판의 상, 하부쪽에서 동시에 맞물려서 절단을 행하게 된다.This arrangement ensures that the mutual symmetry points of the cutting blades 26 and 26 'are secured to cut the strip steel sheet as shown in FIG. do.

이를 상세히 설명하면 횡축(16)(16')에서 길이 R만큼 편심되게 부착된 편심축(15)(15')은 기어의 동력 연결에 의한 횡축(16)(16')의 구동에 따라 절단칼날(26)(26')이 고정 설치된 칼날고정구(11)(11')에 반경 R의 원운동을 부여한다.In detail, the eccentric shafts 15 and 15 'attached eccentrically by the length R in the horizontal shafts 16 and 16' are cut by the driving of the horizontal shafts 16 and 16 'by the power connection of the gears. The circular motion of radius R is given to the blade fasteners 11 and 11 'by which 26 (26') is fixed.

이에 따라서 칼날고정구(11)(11')는 두개의 수직가이드바(12)(12)에 의해 안내되어 띠강판에 대해 상호 대칭하는 지점에 도달한다.Accordingly, the blade fixtures 11 and 11 'are guided by two vertical guide bars 12 and 12 to reach a point symmetrical with respect to the strip steel sheet.

수직가이드바(12)(12)는 주행레일(14)을 타고 최대길이 2R로서 주행되어 제4도에 표시된 바와 같은 절단칼날(26)(26')의 수직위치를 보전한다.The vertical guide bars 12 and 12 travel on the running rail 14 as the maximum length 2R to preserve the vertical position of the cutting blades 26 and 26 'as shown in FIG.

이와 같은 작동에 의한 절단칼날(26)(26')의 원운동이 각각 절단행정을 행하게 되는 것이다.The circular motion of the cutting blades 26 and 26 'by such an operation is to perform the cutting stroke, respectively.

즉, 절단칼날(26)(26')은 띠강판(2)의 운동방향에 대향하는 방향에 있는 편심축의 중심(0)(0')을 잇는 수직선을호부터 절단각 α를 이루는 위치 a로 동시에 접근하여 절단작동을 행하고 수직선상의 점 b에서 상호 교차되어 절단 작동이 완료되며, 절단각 α는 동시에 회전되는 절단칼날(26)(26')의 속도와 띠강판(2)의 공급속도에 의해 결정된다.In other words, the cutting blades 26 and 26 'are moved from the arc to the position a to form the cutting angle α from a vertical line connecting the center of the eccentric axis (0) (0') in the direction opposite to the direction of movement of the strip steel plate 2. At the same time, the cutting operation is performed and the cutting operation is completed by crossing each other at the point b on the vertical line, and the cutting angle α is controlled by the speed of the cutting blades 26 and 26 'and the feeding speed of the strip steel plate 2 which are rotated simultaneously. Is determined.

본 고안에서 모든 절단행정은 구동장치(25)에 설치된 변속기(도면표시 생략)로서 편심축(15)(15')을 동일한 속도로 구동시키는 것에 의해 완벽하게 이루어진다.In the present invention, all cutting strokes are perfectly made by driving the eccentric shafts 15 and 15 'at the same speed as a transmission (not shown) installed in the driving device 25.

또한 칼날 고정구(11)(11')의 수직관통공(19)(19')에는 각각 한 쌍의 쐐기(28)(28')를 하나는 상부에서, 다른 하나는 하부에서 제3도의 표시와 같이 조절가능하게 각각 삽입하고, 수직관통공(19)(19')에 삽입된 쐐기(28)(28')의 삽입 깊이를 조절하는 것에 의해 칼날의 교차시에 용이하게 절단이 이루어지도록 양 절단칼날(26)(26')의 수평 및 간격을 조정할 수 있다.In addition, the vertical through holes 19 and 19 'of the blade fixtures 11 and 11', respectively, have a pair of wedges 28 and 28 ', one at the top and the other at the bottom. Both inserts are adjustable as described above, and both cuttings are easily cut at the intersection of the blades by adjusting the insertion depth of the wedges 28 and 28 'inserted into the vertical through holes 19 and 19'. The horizontal and spacing of the blades 26 and 26 'can be adjusted.

본 고안에 있어서 1회의 절단행정은 상·하부의 편심축(15)(15')이 1회전 되는 것에 의해 완료되며, 절단이 완료된 후에 상·하부의 절단칼날은 최상부와 최하부 위치로 각각 복귀되고, 측정로울러(4)에서 다음의 절단위치를 검출할 때까지 대기한다.In the present invention, one cutting stroke is completed by one rotation of the upper and lower eccentric shafts 15 and 15 ', and after the cutting is completed, the upper and lower cutting blades are returned to the uppermost and lowermost positions, respectively. Wait until the next cutting position is detected by the measuring roller (4).

상부와 하부 절단칼날은 띠강판에 대해 대칭위치를 유지하면서 항상 원운동의 상태로 작동한다.The upper and lower cutting blades always operate in a circular motion while maintaining a symmetrical position with respect to the steel strip.

이와 같은 배치에 의해 띠강판을 소정의 길이로서 정확히 그리고 연속적인 절단을 완벽하게 행할 수 있고, 편심축과 가이드바를 사용하는 것에 의해 각각의 칼날 고정구는 구동중에 원활하게 안내되어 띠강판의 규격이 어긋나지 않게 정확한 절단을 행한다.With this arrangement, the strip steel sheet can be precisely and continuously cut to a predetermined length, and each blade fixture is guided smoothly during operation by using an eccentric shaft and a guide bar, so that the size of the strip steel sheet does not deviate. Make accurate cuttings.

예를 들어 절단각을 정당히 설정하면 절단칼날의 위치가 비스듬히 왜곡되는 일이 없고, 띠강판은 세로 방향으로 곧게 절단된다.For example, if the cutting angle is set properly, the position of the cutting blade is not obliquely distorted, and the strip steel sheet is cut straight in the longitudinal direction.
