Description

투영치수 측정장치Projected dimension measuring device
본 발명은 투영치수 측정장치에 관한 것으로서, 상세하게는 측정대상물의 투영상을 통해 상기 측정대상물의 치수를 자동으로 측정하고, 이렇게 얻은 상기 측정대상물의 측정치수를 가지고 측정대상물의 설계치수로 보정하도록 한 투영치수 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring projection dimensions, and more particularly, to automatically measure the dimensions of the measurement object through a projected image of the measurement object, and correct the measurement object with the measured dimensions of the measurement object obtained in this way to the design dimensions of the measurement object. It relates to a projection dimension measuring device.
보통 설계도면을 가지고 만드는 물건들은 모두 기본적으로 길이, 넓이, 두께 및 각도 등의 다양한 치수를 갖는다. 그런데 이러한 치수들은 상기 물건의 정확한 형상을 특정하는데 필요하며, 일반적으로는 상기 설계도면에 나와있는 치수로 재료를 가공하여 물건을 만들었을 때, 상기 치수대로, 즉 설계치수대로 물건이 만들어졌는지 확인하기 위해 반드시 측정대상물인 물건의 치수에 대한 측정을 실시하게 된다. 이렇게 설계도면에서 지정된 치수인 설계치수의 측정을 통해 상기 설계치수를 벗어나게 되면 치수보정을 하게 되는데, 종래에는 작업자가 직접 측정대상물의 치수를 재서 치수보정을 하게 된다. 즉 직접 측정한 측정대상물의 치수가 설계치수를 벗어나게 되면 상기 측정대상물의 재가공 등을 통해 설계치수에 맞추도록 한다. 그러나 이렇게 작업자가 직접 측정대상물의 치수를 측정하는 것은 오차가 있을 수밖에 없어 치수의 정확성에서 떨어질 뿐만 아니라, 측정대상물 하나하나마다 일일이 치수를 측정하고 있기 때문에 작업효율이 매우 떨어지는 단점이 있다. Usually, all objects made with blueprints have various dimensions such as length, width, thickness, and angle. However, these dimensions are necessary to specify the exact shape of the object, and in general, when the material is processed to the dimensions shown in the design drawing to make the product, it is necessary to check whether the product is made according to the above dimensions, that is, according to the design dimensions. For this purpose, measurements must be made for the dimensions of the object to be measured. In this way, if the design dimension is measured, which is the dimension specified in the design drawing, the dimension is corrected when it deviates from the design dimension. That is, if the dimension of the measurement object directly measured deviates from the design dimension, it is adjusted to the design dimension through re-processing of the measurement object. However, when the operator directly measures the dimensions of the measurement object, there is inevitably an error, which not only reduces the accuracy of the measurement, but also has a disadvantage in that the operation efficiency is very low because the measurement object is measured one by one.
이러한 측정대상물의 치수측정과 치수보정의 예로 종이박스나 옷 등을 제작하기 위한 절단칼이 있다. 즉 종이를 이용하여 제작되는 종이박스는 종이판에 전개도를 그려 절단한 후에 절단된 박스 전개도를 접어 붙임으로써 완성되고, 옷감을 이용하여 제작되는 옷은 상기 옷감에 옷 전개도를 그려 재단한 후에 재봉으로 완성하게 된다. 그런데 이러한 종이판에 그려진 박스 전개도나 옷감에 그려진 옷 전개도를 절단하기 위해서는 상기 전개도의 테두리 형상으로 절단칼이 부착된 절단판을 이용하게 된다.An example of measuring and correcting the dimensions of such a measurement object is a cutting knife for making paper boxes or clothes. That is, a paper box produced using paper is completed by drawing and cutting the unfolded view on a paper plate and then folding and pasting the cut box unfolding view. will be completed However, in order to cut the box unfolded drawing drawn on the paper board or the cloth unfolded drawing drawn on the fabric, a cutting plate with a cutting knife attached to the edge shape of the unfolded view is used.
상기 절단칼은 보통 전개도의 테두리 형상에 맞추어 절곡을 하게 되는데, 이러한 절단칼도 역시 절곡 후에 절곡각도가 설계한 치수대로 되었는지를 확인하기 위해 측정하고 있다. 따라서 이와 같은 경우에도 절곡 후에 절단칼의 절곡각도를 직접 측정하고 측정 후에 설계치수인 설계치수에 맞추어 치수보정을 하고 있다. 그러나 절곡 후에 작업자가 직접 절단칼의 절곡각도를 측정하는 것은 상기한 바와 같이 가공 후에 물건의 치수를 직접 측정하는 것과 동일한 문제점이 발생한다.The cutting knife is usually bent according to the shape of the rim of the developed view, and this cutting knife is also measured to check whether the bending angle is within the designed dimension after bending. Therefore, even in this case, the bending angle of the cutting knife is directly measured after bending, and the dimensions are corrected according to the design dimensions after the measurement. However, when the operator directly measures the bending angle of the cutting knife after bending, the same problem occurs as directly measuring the dimensions of the object after processing as described above.

Unexplained reference numeral 10 in the drawing is a handle for holding the measuring device of the present invention and allowing it to move while pushing or pulling.
이와 같이 구성되는 본 발명에 따른 투영치수 측정장치를 이용하여 측정대상물(3c), 구체적인 예로써는 절단칼의 투영상, 즉 절단칼의 그림자를 가지고 치수를 측정하고 설계치수를 반영하는 과정을 도 1 내지 5를 참조하면서 상세히 설명하도록 한다.The process of measuring the dimensions with the projection image of the cutting knife, that is, the shadow of the cutting knife as a specific example, and measuring the dimensions using the projection size measuring device according to the present invention configured as described above, and reflecting the design dimensions, is shown in FIG. 1 It will be described in detail with reference to to 5.
먼저 측정대상부(3)의 측정판(3a) 상에 측정지그(3b)를 이용하여 절곡기로 가공한 측정대상물(3c)인 절단칼을 고정하고, 상부의 조명부(2)의 LED를 켜 상기 절단칼을 비추도록 하는데, 이렇게 되면 상기 측정판(3a)이 유리판인 투명판(30) 위에 반투명소재인 트레싱지로 구성되므로, 상기 트레이싱지 위에 있는 절단칼은 유리판의 하면에 접하는 부분이 도 5에 도시한 바와 같은 모양으로 투영상, 즉 그림자를 형성하게 된다.First, a cutting knife, which is a measurement object 3c processed by a bending machine using a measurement jig 3b, is fixed on the measurement plate 3a of the measurement object 3, and the LED of the upper lighting unit 2 is turned on. The cutting knife is illuminated. In this case, since the measuring plate 3a is composed of tracing paper, which is a translucent material on the transparent plate 30, which is a glass plate, the cutting knife on the tracing paper is in contact with the lower surface of the glass plate. A projection image, that is, a shadow is formed in the shape as shown.
다음에 측정판(3a) 하부의 촬영부(4)의 카메라 지지대(4a)에 지지되어 고정된 카메라(4b)는 상기 측정판(3a)을 향해 있어, 상기 카메라(4b)가 측정대상물(3c)인 절단칼의 투영상, 즉 상기 절단칼의 그림자를 촬영한다.Next, the camera 4b fixed by being supported by the camera support 4a of the photographing unit 4 under the measuring plate 3a faces the measuring plate 3a, so that the camera 4b moves the measuring object 3c ) of the cutting knife, that is, the shadow of the cutting knife is photographed.

Next, when the shadow of the cutting knife is photographed, as shown in FIG. 5 by the dimension measuring unit 5, the vertical tangent (R) and the horizontal tangent (S) of the shadow of the cutting knife are drawn between the meeting points. Measure the tangent angle (A) and compare it with the angle of the design dimension. However, in normal design dimensions, the tangent angle (A) is 90 degrees, but the angle measured by the dimension measuring unit 5 is approximately less than 90 degrees in most cases, and in rare cases, 70 degrees to 80 degrees. It is measured up to a degree.
다음에 치수측정부(5)에 의해 측정된 치수를 바탕으로 하여 절단칼의 설계치수로 접선각도(A)가 90도에 이르도록 다시 절곡하는 재가공을 치수보정부(6)를 이용하여 절곡기에 명령을 하게 된다.Next, on the basis of the dimensions measured by the dimension measuring part (5), the re-processing of bending again so that the tangential angle (A) reaches 90 degrees with the design dimensions of the cutting knife is performed on the bending machine using the dimension correction part (6). do the command
다음에 상기 절곡기에 의해 재가공된 절단칼을 다시 본 발명의 투영치수 측정장치로 치수를 측정하고 설계치수인 접선각도(A) 90도로 재가공되었는지를 2∼3회 반복하여 실시함으로써, 상기 절곡기에 의해 절단칼을 설계치수로 계속해서 절곡하기 위한 데이터를 확정하게 된다.Next, the size of the cutting knife reprocessed by the bending machine is measured again with the projection dimension measuring device of the present invention, and the design dimension of the tangential angle (A) of 90 degrees is repeated 2-3 times by repeating whether or not it is reprocessed by the bending machine. The data for continuously bending the cutting knife to the design dimensions is confirmed.
한편 이와 같은 본원발명의 투영치수 측정장치에 의해 각종의 부품들이 설계치수로 가공되어 있는지를 확인하는 작업을 절단칼을 예로 들어 설명하였으나, 상기한 바와 같이 절단칼에 한정되지 않고, 가공 후 치수확인이 필요한 절단부재 등의 모든 물건에 적용하여 사용할 수 있을 것이다. On the other hand, the operation of checking whether various parts are processed to the design dimensions by the projection dimension measuring device of the present invention has been described with a cutting knife as an example, but as described above, it is not limited to the cutting knife, and the size check after processing It can be applied and used for all items such as necessary cutting members.
