이하, 본 발명인 필름 에지 측정장치는 첨부된 도 1 내지 도 8을 참고로 상세하게 설명한다. Hereinafter, a film edge measuring device according to the present invention will be described in detail with reference to FIGS. 1 to 8 attached.
본 발명인 필름 에지 측정장치는, 도 1 및 도 2에 도시된 바와 같이 마운팅모듈(100) 및 측정모듈(200)을 포함하며, 도 3에 도시된 바와 같이 지관(20)에 권취된 필름(10)의 에지를 측정한다. The film edge measuring device of the present invention includes a mounting module 100 and a measuring module 200 as shown in FIGS. 1 and 2, and as shown in FIG.
마운팅모듈(100)은, 필름(10)이 권취된 지관(20)이 외측에 끼워지고 지관(20)과 함께 필름(10)을 원주방향으로 회전시키도록 구성된다. 이때, 지관(20)에 권취된 필름(10)은, 에지가 상단과 하단에 위치되게끔 수평하게 뉘어진 상태로 마운팅모듈(100)에 끼워짐이 바람직하다. 본 발명은 도 1 및 도 2에 도시된 바와 같이 소정의 높이에서 수평을 이루는 상면이 마련된 작업대(700)를 더 포함할 수 있으며, 마운팅모듈(100)은, 작업대(700)의 상면에 수직하게 구비되고, 지관(20)의 관통공이 상하방향으로 배치되게끔 필름(10)이 권취된 지관(20)이 마운팅모듈(100)에 끼워질 수 있다. The mounting module 100 is configured such that the paper tube 20 on which the film 10 is wound is inserted into the outside and rotates the film 10 together with the paper tube 20 in the circumferential direction. At this time, the film 10 wound around the branch tube 20 is preferably inserted into the mounting module 100 in a horizontally laid state so that the edges are positioned at the upper and lower ends. As shown in FIGS. 1 and 2, the present invention may further include a work table 700 having a horizontal top surface at a predetermined height, and the mounting module 100 is provided vertically on the top surface of the work table 700, and the branch pipe 20 on which the film 10 is wound so that the through hole of the branch pipe 20 is disposed in the vertical direction may be inserted into the mounting module 100.
이러한 마운팅모듈(100)은, 도 4에 도시된 바와 같이, 압축공기를 이용하여 필름(10)이 권취된 지관(20)을 고정시키거나 고정을 해제시키는 에어척(110)과, 모터로부터 회전력을 전달받아 에어척(110)의 중심을 축으로 하여 에어척(110)을 회전시키는 회전유닛(120)을 포함할 수 있다. As shown in FIG. 4, the mounting module 100 may include an air chuck 110 that fixes or releases the paper pipe 20 on which the film 10 is wound by using compressed air, and a rotating unit 120 that receives rotational force from a motor and rotates the air chuck 110 around the center of the air chuck 110 as an axis.
구체적인 일 예로, 에어척(110)은, 도 4 및 도 5에 도시된 바와 같이 지관(20)의 직경보다 작은 직경을 가지는 원통 형태를 이루면서 수직하게 세워지는 척몸체(111)와, 척몸체(111) 내부에 구비되어 압축공기에 의해 상하방향으로 이동되는 실린더(112)와, 실린더(112)와 인접한 외측에 구비되어 실린더(112)의 상방 이동시 외측으로 돌출되게 이동되고 실린더(112)의 하방 이동시 내측으로 들어가는 죠우(113)를 포함할 수 있다. 예를 들어, 실린더(112)는 원뿔대 형태로 형성되고, 죠우(113)의 내측면은 실린더(112)와 대응되도록 형성될 수 있으며, 죠우(113)의 내측면 상단의 직경은, 실린더(112)의 상단 직경보다 작게 형성될 수 있다. As a specific example, the air chuck 110, as shown in FIGS. 4 and 5, has a chuck body 111 vertically erected while forming a cylindrical shape having a diameter smaller than the diameter of the branch pipe 20, a cylinder 112 provided inside the chuck body 111 and moved in the vertical direction by compressed air, and a cylinder 112 provided on the outside adjacent to the cylinder 112 to protrude outward when the cylinder 112 moves upward, and the cylinder 1 12) may include a jaw 113 that goes inward when moving downward. For example, the cylinder 112 is formed in the shape of a truncated cone, the inner surface of the jaw 113 may be formed to correspond to the cylinder 112, and the diameter of the upper end of the inner surface of the jaw 113 may be smaller than the diameter of the top of the cylinder 112.
이에 따라, 실린더(112)가 척몸체(111)의 하부에 위치될 시 죠우(113)가 내측으로 들어간 상태를 이루어 척몸체(111)보다 돌출되지 않게 되며, 죠우(113)의 외측에 끼워진 지관(20)의 고정이 이루어지지 않는바, 필름(10)이 권취된 지관(20)을 에어척(110)에 끼우거나 에어척(110)에 끼워지고 필름(10)이 권취된 지관(20)을 에어척(110)으로부터 분리시킬 수 있다. 그리고 실린더(112)가 상방으로 이동되어 척몸체(111)의 중앙부에 위치될 시 죠우(113)가 외측으로 돌출되게 이동된 상태를 이루어 척몸체(111)보다 돌출되며, 죠우(113)의 외측에 끼워진 지관(20)의 고정이 이루어진다.Accordingly, when the cylinder 112 is located under the chuck body 111, the jaw 113 is in a state of being inwardly recessed so that it does not protrude beyond the chuck body 111, and the branch tube 20 inserted outside the jaw 113 is not fixed. 0) may separate the rolled branch pipe 20 from the air chuck 110. In addition, when the cylinder 112 is moved upward and positioned at the center of the chuck body 111, the jaw 113 is moved to protrude outward, protruding more than the chuck body 111, and fixing the branch pipe 20 inserted on the outside of the jaw 113.
회전유닛(120)은, 에어척(110)만이 회전되도록 구성될 수 있을 뿐만 아니라, 에어척(110)과 함께 회전되도록 구성될 수 있다. 에어척(110)과 함께 회전되도록 구성되는 경우, 회전유닛(120)은 작업대(700)의 상면에 수평하게 배치되어 회전되도록 구성될 수 있으며, 에어척(110)은 회전유닛(120)의 상측에 일체를 이루도록 결합될 수 있다. 이때, 회전유닛(120)은 다양한 형태로 형성될 수 있으나, 지관(20)의 직경보다 큰 직경을 가지는 원통 형태로 형성됨이 바람직하다. 그리고 원통 형태로 형성된 회전유닛(120)에는, 도 4에 도시된 바와 같이 외측방향으로 봉 또는 막대 형태를 이루는 감지대상봉(121)이 돌출형성될 수 있으며, 감지대상봉(121)과 후술할 감지모듈(500)을 통해 에어척(110)에 고정된 필름(10)의 회전을 감지할 수 있다. The rotation unit 120 may be configured such that only the air chuck 110 rotates, as well as rotated together with the air chuck 110 . When configured to rotate together with the air chuck 110, the rotation unit 120 may be configured to be horizontally disposed on the upper surface of the worktable 700 and rotated, and the air chuck 110 may be integrally coupled to the upper side of the rotation unit 120. At this time, the rotation unit 120 may be formed in various shapes, but is preferably formed in a cylindrical shape having a larger diameter than the diameter of the branch pipe 20. And, as shown in FIG. 4, the rotation unit 120 formed in a cylindrical shape may have a detection target rod 121 protruding outward in the form of a rod or a rod, and the rotation of the film 10 fixed to the air chuck 110 can be sensed through the detection target rod 121 and the detection module 500 to be described later.
측정모듈(200)은, 도 1 및 도 2에 도시된 바와 같이 마운팅모듈(100)에 끼워진 필름(10)의 에지와 대응되는 지점에서 필름(10)으로부터 일정거리 만큼 이격되게 마련될 수 있으며, 마운팅모듈(100)에 의해 필름(10)이 회전되는 과정에서 에지의 변위량을 검출한다. As shown in FIGS. 1 and 2, the measurement module 200 may be spaced apart from the film 10 by a predetermined distance at a point corresponding to the edge of the film 10 inserted into the mounting module 100, and detects the amount of displacement of the edge while the film 10 is rotated by the mounting module 100.
이때, 필름(10)의 에지란, 지관(10)에 권취된 필름(10)의 폭방향 가장자리를 의미하며, 지관(20)에 권취된 필름(10)이 수평하게 뉘어진 상태로 마운팅모듈(100)에 끼워질 시, 필름(10)의 상단과 하단을 이루는 가장자리를 의미한다. 따라서, 본 발명에서는 필름(10)의 상단 가장자리를 필름(10)의 상단 에지라 하며, 필름(10)의 하단 가장자리를 필름(10)의 하단 에지라 한다. 그리고 상기 일정거리란, 측정모듈(200)이 필름(10)의 에지를 검출할 수 있는 측정가능범위 내임을 의미한다. At this time, the edge of the film 10 means the edge in the width direction of the film 10 wound around the paper tube 10, and the film 10 wound around the paper tube 20 is horizontally laid in the mounting module 100. When inserted, it means the edge that forms the top and bottom of the film 10. Therefore, in the present invention, the upper edge of the film 10 is referred to as the upper edge of the film 10, and the lower edge of the film 10 is referred to as the lower edge of the film 10. And the predetermined distance means that the measurement module 200 is within a measurable range capable of detecting the edge of the film 10 .
이러한 측정모듈(200)은, 비접촉식 변위센서로 구성될 수 있으며, 비접촉식 변위센서 중 안정적인 측정이 가능한 레이저 변위센서로 구성됨이 바람직하다. 또한, 레이저 변위센서 중 두 방향의 위치값을 통해 변위량을 검출하는 2D 레이저 변위센서로 구성됨이 보다 바람직하다. Such a measurement module 200 may be composed of a non-contact type displacement sensor, and is preferably composed of a laser displacement sensor capable of stable measurement among non-contact type displacement sensors. In addition, among the laser displacement sensors, it is more preferable to include a 2D laser displacement sensor that detects a displacement amount through position values in two directions.
이와 같은 측정모듈(200)은, 필름(10)의 상단 에지와 하단 에지에 각각 구비되어, 필름(10)의 상단과 하단 모두에 대한 에지 변위량을 검출할 수도 있으나, 장치의 간소화 측면에서, 필름(10)의 상단 에지를 측정한 후 하단 에지를 측정하거나, 필름(10)의 하단 에지를 측정한 후 상단 에지를 측정하도록 구성될 수 있다. 이를 위해, 본 발명은, 도 1, 도 2 및 도 6에 도시된 바와 같이 측정모듈(200)이 필름(10)의 상단 에지에 위치되거나, 필름(10)의 하단 에지에 위치되도록 측정모듈(200)을 상하방향으로 이동시키는 이동모듈(300)을 더 포함할 수 있다. The measurement module 200 as described above is provided at the top edge and the bottom edge of the film 10, respectively, and may detect the amount of edge displacement for both the top and bottom of the film 10. However, in terms of simplification of the device, it may be configured to measure the bottom edge after measuring the top edge of the film 10, or to measure the top edge after measuring the bottom edge of the film 10. To this end, the present invention, as shown in FIGS. 1, 2 and 6, the measurement module 200 is located at the upper edge of the film 10, or the lower edge of the film 10. The movement module 300 for moving the measurement module 200 in the vertical direction may be further included.
이동모듈(300)은, 도 1 및 도 2에 도시된 바와 같이 마운팅모듈(100) 보다 상단이 높게 형성되게끔 형성될 수 있으며, 측정모듈(200)이 전방 측에 상하방향으로 이동가능하게 결합될 수 있다. 여기서, 전방이란 마운팅모듈(100)을 향하는 방향을 의미한다. 구체적으로, 이동모듈(300)은 도 6에 도시된 바와 같이 전단부 양측에 길이방향을 따라 제1 이동레일(310)이 형성된 이동본체부(300a)를 포함할 수 있으며, 측정모듈(200)은 상하방향으로 이동가능하게끔 제1 이동레일(310)과 결합되는 제1 이동부(210)와, 제1 이동부(210)의 전방 측에 고정결합되며 에지의 변위량을 검출하는 측정부(220)를 포함할 수 있다. As shown in FIGS. 1 and 2 , the movable module 300 may be formed to have a higher upper end than the mounting module 100, and the measurement module 200 may be movably coupled to the front side in the vertical direction. Here, the front means a direction toward the mounting module 100 . Specifically, as shown in FIG. 6, the moving module 300 may include a moving body portion 300a having first moving rails 310 formed along the longitudinal direction on both sides of the front end, and the measurement module 200 is movable in the vertical direction. The first moving unit 210 coupled to the first moving rail 310 and fixedly coupled to the front side of the first moving unit 210 and detecting the amount of displacement of the edge A measuring unit 220 may be included.
이때, 제1 이동부(210)의 일측면에는, 일 지점에 제1 위치기호(211)가 표시되고, 이동모듈(300)의 일측면에는, 제1 이동레일(310)과 인접한 후방에 길이방향(상하방향)을 따라 제1 위치눈금자(320)가 구비될 수 있다. 일 예로, 제1 위치기호(211)는 화살표로 구성될 수 있으며, 제1 이동부(210)의 일측면 높이방향 중앙 지점에 표시될 수 있다. 그리고 제1 위치눈금자(320)는 복수 개의 눈금이 일정하게 형성된 자와 같이 구성될 수 있다. At this time, on one side of the first moving unit 210, a first position symbol 211 is displayed at one point, and on one side of the moving module 300, a first position ruler 320 may be provided along the longitudinal direction (vertical direction) at the rear adjacent to the first moving rail 310. For example, the first location symbol 211 may be formed of an arrow and may be displayed at a central point in the height direction of one side of the first moving unit 210 . Also, the first position ruler 320 may be configured like a ruler having a plurality of uniformly formed scales.
측정모듈(200)이 상하방향으로 이동되면, 제1 위치기호(211)가 함께 이동되므로, 사용자는 제1 위치눈금자(320)를 통해 얼마만큼 측정모듈(200)이 상방 또는 하방으로 이동되는지를 손쉽게 알 수 있다. 또한, 측정모듈(200)의 이동범위를 보다 정확히 파악할 수 있게끔 제1 위치눈금자(320)에는, 도 6에 도시된 바와 같이 원점(323), 이동범위의 상한치(321)와 하한치(322)가 표시될 수 있다. 원점(323)은 측정모듈(200)이 상단 에지 또는 하단 에지로 이동되기 전 초기에 위치되는 지점을 의미하고, 이동범위의 상한치(321)는 원점(323)보다 상측에 위치되면서 측정모듈(200)에 의해 필름(10)의 상단 에지를 측정하는 지점을 의미하며, 이동범위의 하한치(322)는 원점(323)보다 하측에 위치되면서 측정모듈(200)에 의해 필름(10)의 하단 에지를 측정하는 지점을 의미한다. When the measurement module 200 is moved in the vertical direction, the first position symbol 211 moves together, so the user can easily know how much the measurement module 200 is moved upward or downward through the first position ruler 320. In addition, as shown in FIG. 6, the origin 323, the upper limit value 321 and the lower limit value 322 of the movement range can be displayed on the first position ruler 320 so that the movement range of the measurement module 200 can be grasped more accurately. The origin 323 means a point initially located before the measurement module 200 moves to the top edge or the bottom edge, and the upper limit value 321 of the movement range is located above the origin 323 and refers to a point where the upper edge of the film 10 is measured by the measurement module 200. It means the point where the lower edge of the film 10 is measured.
그리고 본 발명은 측정모듈(200)의 이동을 제어하는 제어부를 더 포함할 수 있다. 이때 제어부는, 마운팅모듈(100)에 끼워져 측정하고자 하는 필름(10)의 상단과 하단 위치를 고려하여 측정모듈(200)의 이동범위를 사전에 설정할 수 있다. 그리고 측정모듈(200)이 이동범위의 상한치(321) 또는 하한치(322)를 벗어나게 이동시, 제어부는 측정모듈(200)의 작동을 정지시키고 사용자에게 알림을 표시할 수 있다. 여기서의 알림은, 경광등, 사용자 단말로의 메세지 발송 등 다양한 방식일 수 있다. 이를 통해 측정모듈(200)이 오작동하여 필름(10)의 에지를 제대로 측정하지 못하는 것을 효과적으로 방지할 수 있다. And, the present invention may further include a control unit for controlling the movement of the measurement module 200 . At this time, the control unit may set the movement range of the measurement module 200 in advance in consideration of the upper and lower positions of the film 10 to be measured by being inserted into the mounting module 100 . Further, when the measurement module 200 moves beyond the upper limit value 321 or the lower limit value 322 of the movement range, the controller may stop the operation of the measurement module 200 and display a notification to the user. Notification here may be in various ways, such as a warning light or sending a message to a user terminal. Through this, it is possible to effectively prevent the measuring module 200 from malfunctioning and not properly measuring the edge of the film 10 .
상술한 이동모듈(300)은, 필름(10)의 상단 에지 또는/및 하단 에지를 측정시 전방으로 이동되고, 그 측정이 완료되면 후방으로 이동되게끔 구성될 수 있다. 이를 위해 작업대(700)의 상면에서 마운팅모듈(100)로부터 이격된 후방에 마련되는 지지모듈(400)을 더 포함할 수 있다.The moving module 300 described above may be configured to move forward when measuring the top edge or/and bottom edge of the film 10 and move backward when the measurement is completed. To this end, a support module 400 provided at a rear spaced apart from the mounting module 100 may be further included on the upper surface of the work table 700 .
지지모듈(400)은, 일 예로, 도 1 및 도 2에 도시된 바와 같이 소정의 두께를 가지는 판 형태로 형성될 수 있으며, 상측에 이동모듈(300)이 전후방향으로 이동가능하게 결합될 수 있다. 구체적으로, 도 6에 도시된 바와 같이 지지모듈(400)의 상단부 양측에는 제2 이동레일(410)이 형성될 수 있으며, 이동모듈(300)은 상측에 이동본체부(300a)가 마련되고 제2 이동레일(410)과 전후방향으로 이동가능하게 결합되는 제2 이동부(300b)를 더 포함할 수 있다. The support module 400, for example, may be formed in a plate shape having a predetermined thickness, as shown in FIGS. 1 and 2, and the moving module 300 may be movably coupled to the upper side in the forward and backward directions. Specifically, as shown in FIG. 6, the second movable rail 410 may be formed on both sides of the upper end of the support module 400, and the movable module 300 may further include a movable body portion 300a provided on the upper side and a second movable part 300b movably coupled to the second movable rail 410 in the forward and backward directions.
이때, 제2 이동부(300b)의 일측면에는, 일 지점에 제2 위치기호(330)가 표시되고, 지지모듈(400)의 일측면에는, 제2 이동레일(410)과 인접한 하방에 길이방향(전후방향)을 따라 제2 위치눈금자(420)가 구비될 수 있다. 일 예로, 제2 위치기호(330)는 화살표로 구성될 수 있으며, 제2 이동부(300b)의 일측면 전후방향 중앙 지점에 표시될 수 있다. 그리고 제2 위치눈금자(420)는 복수 개의 눈금이 일정하게 형성된 자와 같이 구성될 수 있다. At this time, on one side of the second moving unit 300b, a second position symbol 330 is displayed at one point, and on one side of the support module 400, a second position ruler 420 may be provided along the longitudinal direction (front and back direction) below adjacent to the second moving rail 410. For example, the second location symbol 330 may be formed of an arrow and may be displayed at a central point in the front-back direction of one side of the second moving unit 300b. And, the second position ruler 420 may be configured like a ruler having a plurality of uniformly formed scales.
이동모듈(300)이 전후방향으로 이동되면, 제2 위치기호(330)가 함께 이동되므로, 사용자는 제2 위치눈금자(420)를 통해 얼마만큼 측정모듈(200)이 전방 또는 후방으로 이동되는지를 손쉽게 알 수 있다. 또한, 측정모듈(200)의 이동범위를 보다 정확히 파악할 수 있게끔 제2 위치눈금자(420)에는, 출발점과 한계점이 표시될 수 있다. 출발점은 측정모듈(200)이 측정가능범위 밖에 위치되면서 이동모듈(300)이 전방으로 이동되기 전 초기에 위치되는 지점을 의미하고, 한계점은 측정모듈(200)이 측정가능범위 내에서 측정모듈(200)이 필름(10)과 최인접하게끔 이동모듈(300)이 전방으로 이동되었을 때의 지점을 의미한다. When the movement module 300 is moved forward and backward, the second position mark 330 moves together, so the user can easily know how much the measurement module 200 moves forward or backward through the second position ruler 420. In addition, a starting point and a limit point may be displayed on the second position ruler 420 so that the movement range of the measurement module 200 can be grasped more accurately. The starting point means a point initially located before the moving module 300 moves forward while the measuring module 200 is located outside the measurable range, and the limit point means the point when the moving module 300 is moved forward so that the measuring module 200 is closest to the film 10 within the measurable range.
한편, 전술한 바와 같이 본 발명은 도 1 및 도 2에 도시된 바와 같이 회전유닛(120)에 돌출형성된 감지대상봉(121)을 감지하는 감지모듈(500)을 더 포함할 수 있다. 감지모듈(500)은 마운팅모듈(100)과 지지모듈(400) 사이에 마련될 수 있으며, 일 예로, 도 7에 도시된 바와 같이 제1 위치감지부(510)와, 제1 위치감지부(510)와 소정의 간격 이격된 지점에 구비되는 제2 위치감지부(520)를 포함할 수 있다. Meanwhile, as described above, the present invention may further include a detection module 500 for detecting the detection target bar 121 protruding from the rotation unit 120 as shown in FIGS. 1 and 2 . The sensing module 500 may be provided between the mounting module 100 and the support module 400. For example, as shown in FIG. 7, the first position sensing unit 510 and the first position sensing unit 510 may include a second position sensing unit 520 provided at a point spaced apart from the 510 by a predetermined interval.
본 발명의 제어부는, 감지모듈(500)을 통한 감지대상봉(121)의 감지 정보를 통해 회전유닛(120)의 회전 및 정지를 제어할 수 있다. 예를 들어, 회전유닛(120)이 정지된 상태에서 제1 위치감지부(510)에 의해 감지대상봉(121)이 감지(측정대기 상태)되면 회전유닛(120)을 회전시킨다. 측정대기 상태는, 측정모듈(200)이 필름(10)의 에지와 대응되는 지점에서 상기 필름(10)으로부터 일정거리 만큼 이격된 상태(측정모듈(200)의 측정가능범위 내)를 이루는 것을 전제로 한다.The controller of the present invention may control rotation and stop of the rotation unit 120 through sensing information of the sensing target bar 121 through the sensing module 500 . For example, when the target bar 121 is detected by the first position sensor 510 in a state in which the rotation unit 120 is stopped (measurement standby state), the rotation unit 120 is rotated. The measurement standby state is based on the assumption that the measurement module 200 is spaced apart from the film 10 by a certain distance (within the measurable range of the measurement module 200) at a point corresponding to the edge of the film 10.
만약, 회전유닛(120)이 정지된 상태에서 제1 위치감지부(510)에 의해 감지대상봉(121)이 감지되지 않을 시, 제어부는 회전유닛(120)을 회전시켜 제1 위치감지부(510)에 의해 감지대상봉(121)이 감지될 시 회전유닛(120)을 정지시켜 측정대기 상태를 이루도록 할 수 있다. 또한, 제어부는 측정대기 상태가 이루어지기 전까지 회전유닛(120)이 회전되는 동안에 측정모듈(200)에 의한 에지 측정이 이루어지지 않도록 함이 바람직하다. If the target rod 121 is not sensed by the first position detecting unit 510 while the rotating unit 120 is stopped, the control unit rotates the rotating unit 120. When the target rod 121 is detected by the first position detecting unit 510, the rotating unit 120 may be stopped to achieve a measurement standby state. In addition, the control unit preferably prevents edge measurement by the measurement module 200 from being performed while the rotation unit 120 rotates until the measurement standby state is established.
그리고 제어부는, 측정대기 상태에서 회전유닛(120)의 회전이 시작되고, 제2 위치감지부(520)에 의해 감지대상봉(121)이 감지된 후 제1 위치감지부(510)에 의해 감지대상봉(121)이 다시 감지되면 회전유닛(120)을 정지시킨다. 여기서 제2 위치감지부(520)는, 감지대상봉(121)에 대하여 정지할 상태를 준비하기 위한 감지대상봉(121)을 감지하는 역할을 한다.In addition, the control unit stops the rotation unit 120 when the rotation of the rotation unit 120 starts in the measurement standby state, and the target rod 121 is detected by the second position detector 520, and then the target rod 121 is detected again by the first position detector 510. Here, the second position detecting unit 520 serves to sense the target rod 121 to prepare for a state in which the target rod 121 will stop.
상술한 본 발명인 필름 에지 측정장치에 의해 필름의 하단 에지 및 상단 에지에 대한 변위량이 검출되는 과정을 도 8을 참고하여 살펴보면 다음과 같다. 지관(20)에 권취된 필름(10)이 마운팅모듈(100)에 장착되면, 측정모듈(200)이 측정가능범위 밖에 위치된 상태에서, 이동모듈(300)이 전방으로 이동됨에 따라 측정모듈(200)이 측정가능범위 내에 위치된다. 이후, 측정모듈(200)이 필름(10)의 하단 에지와 대응되는 지점까지 하방으로 이동되면, 마운팅모듈(100)이 1회 회전됨에 따라 필름(10)이 함께 회전되고, 필름(10)이 회전되는 과정에서 측정모듈(200)이 하단 에지의 변위량을 검출한다. 필름(10)의 하단 에지에 대한 변위량 검출이 완료되면, 측정모듈(200)이 필름(10)의 상단 에지와 대응되는 지점까지 상방으로 이동된다. 이후, 마운팅모듈(100)이 1회 회전됨에 따라 필름(10)이 함께 회전되고 필름(10)이 회전되는 과정에서 측정모듈(200)이 상단 에지의 변위량을 검출한다. The process of detecting the amount of displacement for the lower edge and upper edge of the film by the above-described film edge measuring device according to the present invention will be described with reference to FIG. 8 . When the film 10 wound around the paper tube 20 is mounted on the mounting module 100, the measurement module 200 is located outside the measurable range, and as the moving module 300 moves forward, the measurement module 200 is located within the measurable range. Thereafter, when the measurement module 200 is moved downward to a point corresponding to the lower edge of the film 10, the film 10 is rotated together as the mounting module 100 is rotated once, and the measurement module 200 detects the amount of displacement of the lower edge in the process of rotating the film 10. When the detection of the amount of displacement of the lower edge of the film 10 is completed, the measurement module 200 is moved upward to a point corresponding to the upper edge of the film 10 . Thereafter, as the mounting module 100 is rotated once, the film 10 is rotated together, and the measurement module 200 detects the amount of displacement of the top edge while the film 10 is rotated.
본 발명의 제어부는, 측정모듈(200)에 의해 검출된 에지의 변위량을 통해, 필름(10)의 에지 불량 여부를 판별할 수 있다. 일 예로, 제어부는 필름(10)이 1회 회전되는 동안 검출된 에지의 변위량 중 최대값이 사전에 설정된 허용치를 초과하는지 여부를 판별하여, 허용치 초과시 제품 불량으로 판단할 수 있으며, 제품 불량 발생시 사용자에게 알림을 제공할 수 있다. The control unit of the present invention may determine whether the edge of the film 10 is defective through the amount of displacement of the edge detected by the measurement module 200 . For example, the control unit determines whether the maximum value of the displacement amount of the edge detected while the film 10 is rotated once exceeds a preset tolerance value, and determines that the product is defective when the tolerance value is exceeded, and provides a notification to the user when a product defect occurs.
그리고 본 발명은 측정모듈(200)에 의해 검출되는 에지의 변위량을 사용자가 실시간으로 볼 수 있게끔 출력모듈(600)을 더 포함할 수 있으며, 출력모듈(600)은 제품 불량 여부에 대한 결과도 함께 출력할 수 있다. In addition, the present invention may further include an output module 600 so that the user can view the amount of displacement of the edge detected by the measurement module 200 in real time, and the output module 600 may also output a result of whether or not the product is defective.
상술한 바와 같이 본 발명은, 마운팅모듈(100)에 끼워지고 지관(20)에 권취된 지관(10)이 회전되는 동안 측정모듈(200)에 의해 에지의 변위량을 검출하게 되는바, 지관(20)에 권취된 필름(10)의 에지에 대한 돌출 정도를 측정할 수 있다. 이에 따라, 에지의 변위량이 허용치를 벗어날 경우 필름(10)을 불량으로 용이하게 판별할 수 있어, 출하되는 제품의 품질에 대한 신뢰도를 향상시킬 수 있다.As described above, in the present invention, the amount of displacement of the edge is detected by the measurement module 200 while the paper pipe 10 inserted into the mounting module 100 and wound around the paper pipe 20 is rotated, and the degree of protrusion of the edge of the film 10 wound around the paper pipe 20 can be measured. Accordingly, when the amount of displacement of the edge is out of tolerance, the film 10 can be easily determined as defective, and reliability of the quality of the shipped product can be improved.
