또한, 기존 피측정물의 부피를 측정하기 위해서는 피측정물을 한쪽 코너에 밀착시켜야 하는데, 이 경우 코너의 위치에 따라 왼손잡이 또는 오른손잡이 모두를 만족시킬 수 없었다. 하지만, 본 발명은 피측정물을 코너에 밀착시키는 대신 사각 형상의 측정 상판의 일측면에 밀착시키면 되므로 왼손잡이 또는 오른손잡이 모두를 만족시킬 수 있다.In addition, in order to measure the volume of the existing measured object, the measured object should be in close contact with one corner, and in this case, both left-handed and right-handed people could not be satisfied depending on the position of the corner. However, the present invention can satisfy both the left-handed or the right-handed person because the object to be measured is in close contact with one side of the square top plate instead of being in close contact with the corner.

이외에도 본 발명은 피측정물의 면적에 따라 좌우 거리 측정 센서를 연장하여 측정함으로써 측정 상판의 단면적보다 면적이 큰 피측정물을 측정할 수 용이하게 측정할 수 있는 장점이 있다. In addition, the present invention has an advantage that it is possible to easily measure the measured object having a larger area than the cross-sectional area of the measurement top plate by measuring the left and right distance measuring sensor in accordance with the area of the measured object.

좌우 거리 측정 센서가 연장된 상태에서 좌우 거리 측정 센서가 피측정물을 센싱하는 것이 아니라 저울 장치의 측면을 센싱하는 문제점이 발생한다. 이에 본 발명은 측정 상판의 특정 방향으로 길이보다 길이가 작은 피측정물의 경우, 좌우 거리 측정 센서가 연장된 상태에서는 구동되지 않도록 함으로써 피측정물과의 거리 측정 시 발생하는 측정 오류를 줄일 수 있다.In a state in which the left and right distance measuring sensors are extended, a problem arises in that the left and right distance measuring sensors sense the side of the scale apparatus instead of sensing the measured object. Accordingly, the present invention can reduce the measurement error that occurs when measuring the distance to the object to be measured by preventing the object to be measured in the length of the measuring plate is smaller than the length in the extended state, the left and right distance measuring sensor is extended.

Of course, other configuration in addition to the above-described configuration may be included in the measuring device proposed in the present invention. That is, although FIG. 2 illustrates a configuration for measuring the volume of the measurement object, a configuration for measuring the weight of the measurement object is included in the lower portion of the measurement upper plate. Of course, the configuration for measuring the weight of the measurement object will be described later.

베이스(235)는 측정 장치(200)의 저면에 위치한다. 베이스(235)는 일정 두께를 갖는 평판 형상으로 형성된다.The base 235 is located at the bottom of the measuring device 200. The base 235 is formed in a flat plate shape having a predetermined thickness.

측정 상판(225)은 피측정물이 안착될 수 있도록 평판 형태로 구성되며, 상술한 바와 같이 측정 상판(225)의 하부에는 피측정물의 부피를 측정하는 구성 및 엑츄에이터(220)와 깊이 측정 센서(215)의 동작을 연결하는 구성이 형성된다.The measurement top plate 225 is configured in the form of a flat plate so that the measurement object can be seated, and as described above, a configuration for measuring the volume of the measurement object and the actuator 220 and the depth measurement sensor ( A configuration is formed that connects the operations of 215.

엑츄에이터(220)는 평상시에는 연결부재(230)의 외측으로 돌출되며, 가압하면 연결부재(230)의 내측으로 인입된다.The actuator 220 normally protrudes outward from the connection member 230, and when pressed, is introduced into the connection member 230.

깊이 측정 센서(215)는 엑츄에이터(220)와 연동하여 동작한다. 부연하여 설명하면, 엑츄에이터(215)가 연결부재(230)의 외부로 돌출되면 깊이 측정 센서(215)는 측정 상판(225) 아래로 인입되며, 엑츄에이터(215)가 연결부재(230)의 내측으로 인입되면 깊이 측정 센서(215)는 측정 상판(225) 위로 돌출된다.The depth measurement sensor 215 operates in conjunction with the actuator 220. In detail, when the actuator 215 protrudes out of the connecting member 230, the depth measuring sensor 215 is led under the measuring top plate 225, and the actuator 215 is inwardly connected to the connecting member 230. Upon retraction, the depth measurement sensor 215 projects above the measurement top plate 225.

이와 같이 깊이 측정 센서(215)는 평상시 측정 상판(225)의 아래에 위치함으로써 작업자는 깊이 측정 센서(215)와의 부딪힘 없이 피측정물을 측정 상판(225)의 상단에 안착시킬 수 있다.As described above, the depth measurement sensor 215 is positioned below the measurement top plate 225, so that the operator may rest the measurement object on the upper end of the measurement top plate 225 without colliding with the depth measurement sensor 215.

깊이 측정 센서(215)는 피측정물과의 거리를 측정한다. 또한, 깊이 측정 센서(215)는 측정 상판(225)에 안착된 피측정물과의 거리를 측정하기 위해 깊이 측정 센서(215)가 측정 상판(225) 상단으로 이동한 경우에는 깊이 측정 센서(215)에서 조사되는 광의 조사 방향은 측정 상판(225)과 평행한 상태를 유지한다.The depth measuring sensor 215 measures the distance from the object to be measured. In addition, the depth measuring sensor 215 is the depth measuring sensor 215 when the depth measuring sensor 215 moves to the upper end of the measuring top plate 225 to measure the distance to the measurement object seated on the measuring top plate 225. Irradiation direction of the light irradiated from) is maintained in parallel with the measurement top plate (225).

좌우 거리 측정 센서(210)는 측정 상판(225)의 좌측 및 우측에 각각 하나씩 위치하며, 측정 상판(225) 상단에 안착된 피측정물과의 거리를 측정한다. 좌우 거리 측정 센서(210)에서 측정한 정보를 이용하여 피측정물의 좌우 폭을 산출한다.The left and right distance measuring sensors 210 are positioned one each on the left and right sides of the measurement upper plate 225, and measure a distance from the measurement object seated on the upper end of the measurement upper plate 225. The left and right widths of the object to be measured are calculated using the information measured by the left and right distance measuring sensors 210.

높이 측정 센서(205)는 측정 상판(225) 상단에 위치하며, 측정 상판(225) 상단에 안착된 피측정물의 높이를 측정한다. 이를 위해 측정 장치(200)은 일측은 측정 상판(225)과 연결되며, 타측에는 높이 측정 센서(205)가 연결되는 연결부재(230)를 포함한다. 연결부재(230)는 특정 길이는 갖는 바 타입으로 하단은 측정 상판(225)의 모서리 중앙에 위치한 엑츄에이터(220)가 내장될 수 있도록 길이 방향으로 일정한 폭을 갖도록 구성되며, 상술한 바와 같이 타측에는 높이 측정 센서(205)가 연결된다. 일반적으로 연결부재(230)의 길이는 측정 상판(225)에 안착되는 피측정물의 높이보다 상대적으로 길게 형성된다.The height measuring sensor 205 is positioned on the upper end of the measuring upper plate 225, and measures the height of the measurement object seated on the upper end of the measuring upper plate 225. To this end, the measuring device 200 has one side connected to the measurement top plate 225, and the other side includes a connection member 230 to which the height measuring sensor 205 is connected. The connection member 230 is a bar type having a specific length, and the lower end is configured to have a constant width in the longitudinal direction so that the actuator 220 located in the center of the corner of the measurement upper plate 225 is built in. As described above, The height measurement sensor 205 is connected. In general, the length of the connection member 230 is formed relatively longer than the height of the object to be seated on the measurement top plate 225.

또한, 엑츄에이터 검출센서(미도시)는 엑츄에이터가 연결부재(230)의 내부로 인입되었는지 여부를 검출한다. 즉, 엑츄에이터 검출센서는 사용자가 피측정물의 부피를 측정하기 위해 피측정물을 이용하여 엑츄에이터를 가압하였는 지 여부를 검출한다.In addition, the actuator detection sensor (not shown) detects whether the actuator is drawn into the connection member 230. That is, the actuator detecting sensor detects whether the user presses the actuator by using the object under test to measure the volume of the object under test.

엑츄에이터 검출센서에 의해 엑츄에이터가 가압되었다고 판단되면, 구동부재를 이용하여 깊이 측정센서를 상방향으로 이동시키며, 가압된 힘이 제거되면 깊이 측정센서를 하방향으로 이동시킨다.When it is determined that the actuator is pressed by the actuator detection sensor, the depth measuring sensor is moved upward by using the driving member, and when the pressurized force is removed, the depth measuring sensor is moved downward.

이와 같이 본 발명의 측정 장치는 측정 상판(225)의 하단에 위치한 로드셀을 이용하여 피측정물의 중량을 측정하며, 각종 센서를 이용하여 피측정물의 부피를 측정한다.As described above, the measuring device of the present invention measures the weight of the measured object using a load cell located at the lower end of the measuring upper plate 225, and measures the volume of the measured object using various sensors.

도 3은 측정 상판의 상단에 피측정물이 안착되는 예를 도시하고 있다. 도 3에 도시되어 있는 바와 같이 깊이 측정 센서(215)는 측정 상판(225)의 하단에 위치하고 있으며, 엑츄에이터(220)는 연결부재(230)의 외부로 돌출되어 있다.3 illustrates an example in which a measurement object is seated on an upper end of a measurement upper plate. As shown in FIG. 3, the depth measuring sensor 215 is positioned at the lower end of the measuring top plate 225, and the actuator 220 protrudes out of the connection member 230.

도 4는 피측정물을 이용하여 엑츄에이터를 가압하는 예를 도시하고 있다. 도 4에 도시되어 있는 바와 같이 피측정물이 엑츄에이터(220)를 가압하면, 엑츄에이터(220)는 연결부재(230)의 내측으로 인입되며, 깊이 측정 센서(215)는 측정 상판(225)의 상측으로 돌출된다. 전원을 공급받은 각종 센서(205, 210, 215)는 피측정물과의 거리를 측정한다.4 shows an example of pressurizing the actuator by using the measurement object. As shown in FIG. 4, when the measured object pressurizes the actuator 220, the actuator 220 is introduced into the connection member 230, and the depth measuring sensor 215 is located above the measurement upper plate 225. Protrudes. The various sensors 205, 210, and 215 that are supplied with power measure the distance to the object to be measured.

부연하여 설명하면, 엑츄에이터(220)를 가압하면, 엑츄에이터(220)의 구동과 연동되는 깊이 측정 센서(215)는 측정 상판(225)의 상측으로 돌출된다. 측정 상판(225)의 상측으로 깊이 측정 센서(215)가 돌출되면, 깊이 측정 센서(215)를 포함한 좌우 거리 측정 센서(210), 높이 측정 센서(205)가 피측정물과의 거리를 측정한다. In detail, when the actuator 220 is pressurized, the depth measuring sensor 215 interlocked with the driving of the actuator 220 protrudes above the measurement upper plate 225. When the depth measuring sensor 215 protrudes above the measuring upper plate 225, the left and right distance measuring sensor 210 including the depth measuring sensor 215, and the height measuring sensor 205 measure the distance from the measured object. .

도 5는 측정 상판에 안착된 피측정물의 중량 및 부피 측정이 완료된 이후 측정 상판에서 피측정물을 분리하는 예를 도시하고 있다. 측정 상판(225)에서 피측정물을 분리하면, 연결부재(230)의 내측에 인입되어 있던 엑츄에이터(220)가 원래 위치로 복원되며, 엑츄에이터(220)가 원래 위치로 복원되면 깊이 측정 센서(215)는 측정 상판(225)의 하단으로 이동한다.FIG. 5 shows an example of separating a measurement object from the measurement top plate after the measurement of the weight and volume of the measurement object seated on the measurement top plate is completed. When the measurement object is removed from the measurement top plate 225, the actuator 220 retracted into the inner side of the connecting member 230 is restored to the original position, and when the actuator 220 is restored to the original position, the depth measuring sensor 215 ) Moves to the bottom of the measurement top plate 225.

이와 같이 본 발명은 엑츄에이터의 이동에 따라 깊이 측정 센서를 측정 상판의 표면 상단 또는 하단으로 이동시킨다.As such, the present invention moves the depth measurement sensor to the upper or lower surface of the measurement top plate according to the movement of the actuator.

도 6은 본 발명의 일실시 예에 따른 좌우 거리 측정 센서가 연장된(늘어난) 경우를 도시하고 있다. 이하 도 6을 이용하여 본 발명의 일실시 예에 따른 좌우 거리 측정 센서가 연장된 경우에 대해 상세하게 알아보기로 한다.6 illustrates a case in which the left and right distance measuring sensors according to the exemplary embodiment of the present invention are extended (extended). Hereinafter, a case in which the left and right distance measuring sensor according to an embodiment of the present invention is extended will be described in detail with reference to FIG. 6.

도 6에 의하면, 좌우 거리 측정 센서(210)는 좌측 거리 측정 센서(210a)와 우측 거리 측정 센서(210b)로 구성되며, 좌측 거리 측정 센서(210a)와 우측 거리 측정 센서(210b) 중 어느 하나의 센서가 연장된다. 도 6에서는 좌측 거리 측정 센서(210a)가 연장된 경우를 도시하고 있으나, 이에 한정되는 것은 아니다.Referring to FIG. 6, the left and right distance measuring sensor 210 includes a left distance measuring sensor 210a and a right distance measuring sensor 210b, and any one of the left distance measuring sensor 210a and the right distance measuring sensor 210b. The sensor of is extended. 6 illustrates a case in which the left distance measuring sensor 210a is extended, but is not limited thereto.

부연하여 설명하면, 좌측 거리 측정 센서(210a)가 연장된 상태에서 측정 장치를 구성하는 센서는 피측정물과의 거리를 측정한다. 물론 측정 장치는 좌측 거리 측정 센서(210a)가 연장된 경우, 좌측 거리 측정 센서(210a)와 우측 거리 측정 센서(210b) 사이의 거리를 저장하고 있으며, 이를 기반으로 측정 장치는 피측정물의 좌우 거리를 산출한다.In detail, the sensor constituting the measuring device in the state in which the left distance measuring sensor 210a is extended measures the distance to the object to be measured. Of course, when the left distance measuring sensor 210a is extended, the measuring device stores the distance between the left distance measuring sensor 210a and the right distance measuring sensor 210b. Calculate

도 7은 본 발명의 다른 실시 예에 따른 좌우 거리 측정 센서가 연장된(늘어난) 경우를 도시하고 있다. 도 7은 도 6과 달리 측정 상판에 안착된 피측정물의 좌우 길이가 측정 상판의 좌우 길이보다 작은 경우를 도시하고 있다. 부연하여 설명하면, 측정 상판 내에 피측정물이 안착된 상태에서 좌우 거리 측정 센서가 연장된 경우를 도시하고 있다.7 illustrates a case in which the left and right distance measuring sensors according to another embodiment of the present invention are extended (extended). FIG. 7 illustrates a case in which the left and right lengths of the measurement object seated on the measurement top plate are smaller than the left and right lengths of the measurement top plate, unlike in FIG. 6. In detail, the left and right distance measuring sensors are extended in a state where the object to be measured is placed in the measurement upper plate.

도 7에 의하면, 연장이 가능한 좌우 거리 측정 센서가 형성된 측면에 감지 센서(255)가 형성된다. 부연하여 설명하면, 측정 상판의 하단에 위치하는 베이스의 측면에 감지 센서(255)가 형성되며, 감지 센서(255)는 피측정물을 감지한다. 부연하여 설명하면, 좌측 거리 측정 센서(210a)가 연장된 상태에서 측정 상판을 상단에서 바라볼 경우, 감지 센서(255)는 외부로 노출된다.According to FIG. 7, a sensing sensor 255 is formed on a side surface on which the extendable left and right distance measuring sensor is formed. In detail, the sensing sensor 255 is formed on the side of the base positioned at the lower end of the measurement upper plate, and the sensing sensor 255 senses the object to be measured. In detail, when the measurement top plate is viewed from the top in the state where the left distance measuring sensor 210a is extended, the sensing sensor 255 is exposed to the outside.

측정 상판에 안착된 피측정물이 측정 상판 내에 안착된 경우에는 감지 센서(255)는 피측정물을 감지할 수 없다. 하지만, 측정 상판에 안착된 피측정물이 측정 상판 외부로 돌출된 경우에는 감지 센서(255)는 피측정물이 감지된다.When the object to be mounted on the measurement top plate is seated in the measurement top plate, the detection sensor 255 may not detect the object to be measured. However, when the object to be mounted on the measurement top plate protrudes out of the measurement top plate, the detection sensor 255 detects the measurement object.

본 발명은 감지 센서(255)에 의해 피측정물이 감지된 경우, 좌우 거리 측정 센서는 좌측 거리 측정 센서(210a)가 연장된 상태에서 피측정물과의 거리를 측정한다. 부연하여 설명하면, 감지 센서(255)에 의해 피측정물이 감지되지 않은 경우에는 좌우 거리 측정 센서는 좌측 거리 측정 센서(210a)가 연장된 상태에서 피측정물과의 거리를 측정(구동)하지 않는다. 즉, 감지 센서(255)에 의해 피측정물이 감지되지 않은 경우에는 좌우 거리 측정 센서는 좌측 거리 측정 센서(210a)가 연장되지 않은 상태에서 피측정물과의 거리를 측정한다.According to the present invention, when the object to be detected is detected by the sensor 255, the left and right distance measuring sensors measure the distance to the object to be measured while the left distance measuring sensor 210a is extended. In detail, when the measured object is not detected by the detection sensor 255, the left and right distance measuring sensors do not measure (drive) the distance from the measured object while the left distance measuring sensor 210a is extended. Do not. That is, when the object to be measured is not detected by the detection sensor 255, the left and right distance measuring sensor measures the distance to the object to be measured while the left distance measuring sensor 210a is not extended.

이에 대해 구체적으로 살펴보면, 피측정물의 좌우 길이가 측정 상판의 좌우 길이보다 작은 경우, 즉 피측정물이 측정 상판 내에 안착되는 경우에 좌측 거리 측정 센서(210a)가 연장된 상태에서 좌우 거리 측정 센서가 피측정물과의 거리를 측정하는 것으로 가정한다. 이 경우, 좌우 거리 측정 센서는 피측정물과의 거리를 측정하는 것이 아니라 피측정물보다 상대적으로 가까운 측정 상판의 측면과의 거리를 측정하는 문제점이 발생한다.In detail, when the left and right lengths of the measured object are smaller than the left and right lengths of the measurement upper plate, that is, when the measured object is seated in the measurement upper plate, the left and right distance measuring sensors are extended in a state where the left distance measuring sensor 210a is extended. Assume that the distance to the object under measurement is measured. In this case, the left and right distance measuring sensor does not measure the distance to the object to be measured, but a problem of measuring the distance to the side of the measurement upper plate that is relatively closer than the object to be measured.

본 발명은 이와 같은 문제점을 해결하기 위해 베이스의 측면에 감지 센서를 형성하고, 감지 센서가 피측정물을 감지한 경우, 좌측 거리 측정 센서가 연장된 상태에서도 좌우 거리 측정 센서가 피측정물과의 거리를 측정한다.In order to solve the above problems, the present invention forms a detection sensor on the side of the base, and when the detection sensor detects the object to be measured, the left and right distance measurement sensor is connected to the object to be measured even when the left distance sensor is extended. Measure the distance.

도 8은 본 발명의 일실시 예에 따른 좌측 거리 측정 센서가 연장된 상태를 도시하고 있다. 이하 도 8을 이용하여 본 발명의 일실시 예에 따른 좌측 거리 측정 센서가 연장된 상태를 상세하게 알아보기로 한다.8 illustrates an extended state of the left distance measuring sensor according to the exemplary embodiment of the present invention. Hereinafter, a state in which the left distance measuring sensor is extended according to an embodiment of the present invention will be described in detail with reference to FIG. 8.

도 8에 의하면, 측정 장치는 좌측 거리 측정 센서, 우측 거리 측정 센서, 슬라이드 가이드, 로드셀, 베이스, 제1 위치 측정 센서, 제2 위치 측정 센서 및 감지센서를 포함한다. 물론 상술한 구성 이외에 다른 구성이 본 발명에서 제안하는 측정 장치에 포함할 수 있다.According to FIG. 8, the measuring device includes a left distance measuring sensor, a right distance measuring sensor, a slide guide, a load cell, a base, a first position measuring sensor, a second position measuring sensor, and a sensing sensor. Of course, in addition to the above-described configuration, other configurations may be included in the measurement device proposed in the present invention.

베이스(235)는 측정 장치(200)의 저면에 위치한다. 베이스(235)는 일정 두께를 갖는 평판 형상으로 형성된다.The base 235 is located at the bottom of the measuring device 200. The base 235 is formed in a flat plate shape having a predetermined thickness.

로드셀(240)의 상단에는 측정 상판(225)이 위치한다. 측정 상판(225)은 평판 형태로 구성되며, 상단에 피측정물이 안착된다. 즉, 측정 상판(225)에 피측정물이 안착되면, 피측정물이 측정 상판(225)을 가압하며, 측정 상판(225)은 로드셀(240)을 가압한다. 로드셀(240)은 측정 상판(225)을 포함한 피측정물의 중량을 측정하며, 이후 기 저장된 측정 상판(225)의 중량을 차감하여 피측정물의 중량을 측정한다. 물론 로드셀(240)은 측정 상판(225)의 상단에 피측정물이 올려지기 전과 올려진 후의 중량 차이를 이용하여 피측정물의 중량을 측정할 수 있다.The measurement top plate 225 is positioned at the top of the load cell 240. The measurement top plate 225 is configured in the form of a flat plate, on which the object to be measured is seated. That is, when the measurement object is seated on the measurement top plate 225, the measurement object presses the measurement top plate 225, and the measurement top plate 225 presses the load cell 240. The load cell 240 measures the weight of the measurement object including the measurement top plate 225, and then subtracts the weight of the previously stored measurement top plate 225 to measure the weight of the measurement object. Of course, the load cell 240 may measure the weight of the measured object by using the difference in weight before and after being placed on the upper end of the measurement upper plate 225.

우측 거리 측정 센서(210b)는 측정 장치의 측정 상판(225)의 우측 상단에 위치하며, 피측정물과의 거리를 센싱한다. 좌측 거리 측정 센서(210a)는 측정 장치의 측정 상판(225)의 좌측 상단에 위치한다. 또한, 상술한 바와 같이 좌측 거리 측정 센서(210a)는 측정 상판의 좌측 상단에서 좌측 방향으로 연장된다. 이를 위해 슬라이드 가이드(245)의 일측에 좌측 거리 측정 센서(210a)가 고정된다.The right distance measuring sensor 210b is positioned on the upper right side of the measurement upper plate 225 of the measuring device and senses a distance from the object to be measured. The left distance measuring sensor 210a is located on the upper left side of the measurement upper plate 225 of the measuring device. In addition, as described above, the left distance measuring sensor 210a extends in the left direction from the upper left of the measurement upper plate. To this end, the left distance measuring sensor 210a is fixed to one side of the slide guide 245.

슬라이드 가이드(245)는 상술한 바와 같이 일측에 좌측 거리 측정 센서(210a)가 위치하며, 측정 장치 내에서 좌측에서 우측으로, 우측에서 좌측으로 이동한다.As described above, the slide guide 245 has a left distance measuring sensor 210a positioned at one side and moves from left to right and right to left in the measuring device.

제1 위치 측정 센서(250a)는 슬라이드 가이드(245)가 제1 위치에 위치하는지 여부를 센싱한다. 제1 위치는 슬라이드 가이드가 연장되지 않은 경우, 즉 좌측 거리 측정 센서(210a)가 연장되지 않은 위치이다. The first position measuring sensor 250a senses whether the slide guide 245 is located at the first position. The first position is a position where the slide guide is not extended, that is, the left distance measuring sensor 210a is not extended.

제2 위치 측정 센서(250b)는 슬라이드 가이드(245)가 제2 위치에 위치하는지 여부를 센싱한다. 제2 위치는 슬라이드 가이드(245)가 연장된 경우, 즉 좌측 거리 측정 센서(210a)가 연장된 위치이다.The second position measuring sensor 250b senses whether the slide guide 245 is located at the second position. The second position is a position where the slide guide 245 is extended, that is, the left distance measuring sensor 210a is extended.

측정 장치는 제1 위치 측정 센서(250a) 또는 제2 위치 측정 센서(250b)로부터 전달받은 정보를 이용하여 좌측 거리 측정 센서(210)의 연장 여부를 파악한다.The measuring device determines whether the left distance measuring sensor 210 is extended by using information received from the first position measuring sensor 250a or the second position measuring sensor 250b.

이와 같이 본 발명의 측정 장치는 좌측 거리 측정 센서를 연장함으로써 피측정물의 특정 방향으로의 길이가 측정상판(작업대)의 해당 방향으로의 길이보다 큰 경우에도 피측정물의 부피를 측정할 수 있다.As described above, the measuring device of the present invention can measure the volume of the measured object even when the length in the specific direction of the measured object is greater than the length in the corresponding direction of the measuring table (work table) by extending the left distance measuring sensor.

감지센서(255)는 측정 상판의 측면 외부로 노출된 피측정물을 감지한다. 상술한 바와 같이 감지센서(255)가 피측정물을 감지한 경우에만, 좌측 거리 측정 센서(210a)가 연장된 상태에서 피측정물과의 거리를 측정한다. 즉, 감지센서(255)가 피측정물을 감지하지 않은 상태에서는 좌측 거리 측정 센서(210a)가 연장된 상태에서는 피측정물과의 거리를 측정하지 않으며, 좌측 거리 측정 센서(210a)가 연장되지 않은 상태에서 피측정물과의 거리를 측정한다. 물론 좌측 거리 측정 센서(210a)가 피측정물과의 거리를 측정하는 경우, 우측 거리 측정 센서 역시 피측정물과의 거리를 측정한다. 물론 좌우 거리 측정 센서의 측정 여부와 상관없이, 높이 측정 센서, 깊이 측정 센서는 피측정물과의 거리를 측정할 수 있다.The detection sensor 255 detects the measurement object exposed to the outside of the side of the measurement top plate. As described above, only when the sensor 255 detects the object to be measured, the distance to the object to be measured is measured in a state in which the left distance measuring sensor 210a is extended. That is, in the state in which the sensor 255 does not detect the object to be measured, the distance to the object to be measured is not measured when the left distance sensor 210a is extended, and the left distance sensor 210a is not extended. Measure the distance from the object under test Of course, when the left distance measuring sensor 210a measures the distance to the object to be measured, the right distance measuring sensor also measures the distance to the object to be measured. Of course, the height measuring sensor and the depth measuring sensor may measure the distance to the object to be measured, regardless of whether the left and right distance measuring sensors are measured.

이외에도 본 발명의 측정 장치는 카메라를 추가로 포함될 수 있다. 일 예로 높이 측정 센서 또는 연결부재에 카메라를 설치하며, 카메라는 측정 상판에 안착된 피측정물의 상부를 측정한다. 일 예로 카메라는 피측정물의 상부에 부착된 기표지를 촬영한다. 물론 본 발명의 측정 장치는 높이 측정 센서 또는 연결부재 이외에 다른 부위에 카메라를 설치할 수 있다.In addition, the measuring device of the present invention may further include a camera. For example, a camera is installed in the height measuring sensor or the connecting member, and the camera measures the upper part of the measurement object seated on the measuring top plate. As an example, the camera photographs a sign attached to the upper part of the object to be measured. Of course, the measuring device of the present invention can be installed in the camera other than the height measuring sensor or the connecting member.
