산업체의 각종 부품의 생산 시 또는, 우체국에서 처리하는 우편 배송물이나 각종 수하물 등의 접수 처리시, 정확한 중량 측정은 필수적이다.Accurate weight measurement is essential in the production of various parts of the industry, or in the reception of postal items or various baggage handled by the post office.
예를 들어, 산업체에서는 기구나 장치 부품의 중량 측정이 다양하게 요구되고, 우체국과 택배회사 등에서 처리하는 우편 배송물이나 각종 수하물은 중량에 따라 비용(요금)이 결정될 수 있기 때문에, 정확한 무게측정이 필요한 것이다.For example, in the industry, various weighing of apparatus or device parts is required, and postal shipments and various baggage handled by post offices and courier companies can be determined according to the weight.

그런데, 통상 산업체나 우체국 등에서는 지금까지 알려진 저울(소형 또는 대형 저울)을 구매하여, 저울 위에 무게를 측정하기 위한 피측정물 즉, 우편 배송물이나 수하물 등을 단순하게 올려놓고, 중량을 측정하는 것이 일반적인 것이었다.However, in general, an industry or a post office purchases a scale (small or large scale) known to date, and simply puts an object to be weighed on the scale, that is, mail or baggage, and measures the weight. Was common.
도 1은 종래 피측정물의 중량 및 부피를 측정하는 장치를 도시하고 있다.1 shows an apparatus for measuring the weight and volume of a conventional measured object.
도 1에 도시되어 있는 바와 같이 피측정물의 부피는 3개의 센서를 이용하여 피측정물의 가로 길이, 세로 길이 및 높이를 측정하고, 측정한 가로 길이, 세로 길이 및 높이를 이용하여 피측정물의 부피를 산출한다.As shown in FIG. 1, the volume of the object to be measured is measured using three sensors. The width, length, and height of the object to be measured are measured, and the volume of the object to be measured is measured by using the measured length, height, and height. Calculate
하지만, 도 1에 도시되어 있는 바와 같이 피측정물의 부피를 측정하는 3개의 센서 중 피측정물의 가로 길이 및 세로 길이를 측정하는 센서는 장치의 외측에 노출된 상태로 위치한다. 이와 같이 센서가 장치의 외측에 노출됨으로써 작업자는 피측정물을 작업대로 이동시키거나, 작업대로부터 피측정물을 빼낼 때 센서에 부딪히지 않도록 주의해서 작업을 해야 한다. 또한, 종래 측정 장치는 피측정물을 작업대의 한쪽 코너에 밀착시켜야 측정이 가능하다는 불편함이 있다.However, as shown in FIG. 1, of the three sensors measuring the volume of the object under test, the sensor measuring the horizontal length and the vertical length of the object under test is positioned exposed to the outside of the apparatus. As the sensor is exposed to the outside of the device in this way, the operator should be careful not to hit the sensor when moving the object to the workbench or removing the object from the workbench. In addition, the conventional measuring device is inconvenient that the measurement is possible only if the object to be measured in close contact with one corner of the work table.
본 발명이 해결하려는 과제는 피측정물의 부피 및 중량을 측정하기 위해 피측정물을 작업대에 올려놓을 경우 센서와 부딪히는 불편함을 감소시키는 방안을 제안함에 있다.The problem to be solved by the present invention is to propose a method for reducing the inconvenience of hitting the sensor when the object to be placed on the work table to measure the volume and weight of the object to be measured.
본 발명이 해결하려는 다른 과제는 피측정물의 부피 및 중량을 측정하기 위해 피측정물을 작업대의 한쪽 코너에 밀착시켜야 하는 불편함을 감소시키는 방안을 제안함에 있다.Another problem to be solved by the present invention is to propose a method for reducing the inconvenience that the object to be closely adhered to one corner of the work table in order to measure the volume and weight of the object.
본 발명이 해결하려는 또 다른 과제는 피측정물의 특정면이 평탄하지 않은 경우에도 피측정물의 높이를 기존 대비하여 상대적으로 정확하게 측정하는 방안을 제안함에 있다.Another problem to be solved by the present invention is to propose a method for measuring the height of the measured object relatively accurately even when the specific surface of the measured object is not flat.
이를 위해 본 발명의 측정 장치는 평판 타입으로 형성되는 측정 상판; 일측이 상기 측정 상판과 밀착되며, 일정 길이를 갖는 막대 타입을 포함하는 연결부재; 상기 측정 상판에 좌측에 형성되는 좌측 거리 측정 센서와 상기 측정 상판의 우측에 형성되는 우측 거리 측정 센서 중 적어도 하나를 포함하는 거리 측정 센서; 상기 연결부재의 타측에 형성되는 높이 측정 센서; 및 상기 측정 상판의 일측에 형성되는 깊이 측정 센서를 포함하며, 상기 거리 측정 센서, 높이 측정 센서 또는 깊이 측정 센서 중 적어도 어느 하나의 센서는 제1 센서 어레이와 제2 센서 어레이를 포함하며, 상기 제1 센서 어레이는 제1 발광부와 제1 수광부를 포함하며, 상기 제2 센서 어레이는 제2 발광부와 제2 수광부를 포함한다.To this end, the measuring device of the present invention comprises a measuring top plate formed of a flat plate type; One side is in close contact with the measurement top plate, the connecting member including a rod type having a predetermined length; A distance measuring sensor including at least one of a left distance measuring sensor formed at a left side of the measuring top plate and a right distance measuring sensor formed at a right side of the measuring top plate; A height measuring sensor formed on the other side of the connection member; And a depth measuring sensor formed on one side of the measuring upper plate, wherein at least one of the distance measuring sensor, the height measuring sensor, or the depth measuring sensor includes a first sensor array and a second sensor array. The first sensor array includes a first light emitting unit and a first light receiving unit, and the second sensor array includes a second light emitting unit and a second light receiving unit.
본 발명에 따른 부피 및 중량 자동 측정 장치 및 이를 이용한 소포 접수 방법은 피측정물을 부피를 측정하는 센서가 평상시에는 피측정물이 안착되는 측정 상판의 하단에 위치함으로써 사용자가 측정 상판에 피측정물을 올려놓는 경우, 센서와 부딪힐 가능성을 줄어들게 된다.The automatic volume and weight measurement apparatus according to the present invention and the method for receiving parcels using the same are provided in which a sensor for measuring a volume of a measurement object is normally positioned at the bottom of a measurement top plate on which the measurement object is seated. If you put it on, it will reduce the chance of hitting the sensor.
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 복수의 높이 측정 센서를 이용하여 피측정물의 상단면이 평탄하지 않은 경우에도 기존 대비하여 상대적으로 피측정물의 높이를 정확하게 측정할 수 있다. 또한, 피측정물의 상단면 뿐만 아니라 측면이 평탄하지 않은 경우에도 좌우 거리 측정 센서 또는 길이 측정 센서를 이용하여 피측정물의 길이를 정확하게 측정할 수 있다.In addition, the present invention can accurately measure the height of the object to be measured relatively compared to the conventional case even when the top surface of the object to be measured is not flat using a plurality of height measuring sensors. In addition, even when the side surface is not flat as well as the top surface of the object to be measured, the length of the object to be measured can be accurately measured using a left and right distance measuring sensor or a length measuring sensor.

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).

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.
