본 발명은 콘크리트의 성능개선이 요구될 때 콘크리트에 일정비율로 투입되는 혼화제가 계량장치의 고장으로 인하여 투입 불량되는 현상을 방지하는 혼화제 투입불량 방지장치에 관한 것이다.The present invention relates to an admixture preventing device for preventing admixtures in which admixtures injected into the concrete at a predetermined ratio when the performance improvement of the concrete is required are prevented from being poorly input due to the failure of the metering device.

일반적으로 콘크리트에는 콘크리트 구조물의 내구성과 강도의 향상 및 건축물에서 요구하는 다른 특성들을 향상시키기 위하여 다양한 조성물들로 이루어진 혼화제가 투입된다.In general, concrete is added to the admixture made of various compositions to improve the durability and strength of the concrete structure and other properties required by the building.

이러한 콘크리트 혼화제는 통상 혼화제를 구성하는 조성물들이 원재료로 입하되어 분쇄 및 교반과정을 거쳐 별도의 저장탱크들 내부에 액상으로 각각 저장되어 있다가, 콘크리트 제조공정 중에 각각 일정량이 투입되어 콘크리트에 골고루 혼합된다.These concrete admixtures are usually stored in liquid form in separate storage tanks through the crushing and stirring process, the composition constituting the admixture as a raw material, and a predetermined amount is added to each concrete during the concrete manufacturing process, evenly mixed in the concrete. .

도 1에 도시된 바와 같이, 종래의 혼화제 투입장치는 혼화제를 구성하는 조성물들이 각각 별도로 저장되는 저장탱크(10)와, 상기 저장탱크(10)와 연결되어 저장탱크(10)로부터 각각의 계량조(30)로 배출되는 각각의 조성물들의 중량을 체크하는 계량장치(20)로 구성된다.As shown in FIG. 1, the conventional admixture injector is a storage tank 10 in which the compositions constituting the admixture are stored separately, and connected to the storage tank 10, respectively, from each of the weighing tanks. It consists of a metering device 20 for checking the weight of each composition discharged to (30).

상기 계량장치(20)는 혼화제를 구성하는 각각의 조성물들이 콘크리트 내에 정확한 양으로 투입될 수 있도록 저장탱크(10)로부터 배출되는 조성물들의 중량을 측정하고 이로부터 정상적인 혼화제의 투입이 이루어지는지 확인한다.The metering device 20 measures the weight of the composition discharged from the storage tank 10 so that each of the compositions constituting the admixture can be introduced into the concrete in the correct amount and confirms that the normal admixture is made therefrom.

또한, 상기 저장탱크(10)에는 수위센서(11)가 설치되어 저장탱크(10) 내부로 혼화제가 과투입되는 것을 감지하고 과투입이 감지되었을 경우, 외부 저장탱크의 압송펌프의 작동을 멈추게 하여 혼화제가 저장탱크(10)로 투입되는 것을 막도록 구성되어 있다.In addition, the storage tank 10 has a water level sensor 11 is installed to detect that the admixture is over-injected into the storage tank 10, and when the over-injection is detected, by stopping the operation of the pressure pump of the external storage tank It is configured to prevent the admixture is introduced into the storage tank (10).

그러나, 이러한 혼화제투입장치는 배출되는 조성물들의 중량을 단지 계량장 치(20)로만 측정하도록 되어 있다. 따라서 계량장치(20)에 고장이 발생될 경우, 고장발생 여부를 작업자가 이를 즉시 인지하기가 힘들어 작업자가 이를 인지할 때까지 상당량의 콘크리트가 불량으로 출하되는 문제점이 있었다.However, this admixture dosing device is adapted to measure the weight of the composition to be discharged only with the metering device 20. Therefore, when a failure occurs in the metering device 20, it is difficult for the worker to immediately recognize whether or not a failure occurred, there was a problem that a considerable amount of concrete is shipped as a defective until the worker recognizes it.

설령, 작업자가 고장여부를 즉시 인지하였다 하더라도, 작업자가 혼화제 투입을 즉시 정지시키는 데에는 어느 정도 시간이 소요되고, 대단위로 연속적으로 투입되는 공정특성상 상기 시간 동안 제조된 상당량의 콘크리트가 모두 불량 처리될 수 밖에 없어 생산량이 저하된다.Even if the worker immediately recognizes the failure, it takes some time for the worker to stop the admixture immediately, and due to the process characteristics that are continuously injected in large units, a considerable amount of concrete produced during the above time may be all treated badly. There is only production, which reduces production.

더욱이, 육안으로는 콘크리트의 불량여부를 확인하기가 매우 어렵기 때문에 불량이 예상되는 콘크리트 역시 함께 폐기되어야 하므로 생산성은 더욱 저하된다.Moreover, since it is very difficult to check whether the concrete is defective by the naked eye, productivity is further lowered because the concrete which is expected to be defective should be discarded together.

이러한 현상을 방지하고자 적소에 카메라를 설치하여 배출되는 조성물들의 상태를 감시하고는 있으나, 이 경우 작업자가 계량장치의 이상 유무 및 혼화제 투입이 원활하게 이루어지고 있는지 항상 주시하여야 하므로 관리상의 어려움이 뒤따르며, 이 경우 역시 계량장치의 고장여부를 즉시 인지하였다 하더라도 상기에 기재한 바와 같은 문제점은 여전히 해결하지 못한다.In order to prevent this phenomenon, a camera is installed in place to monitor the state of the discharged compositions, but in this case, the operator has to keep an eye on whether there is an abnormality in the metering device and the admixture of the admixture. In this case, the problem as described above is still not solved even if it is immediately recognized whether the metering device is out of order.

본 발명은 상기와 같은 문제점들을 해소하기 위해 이루어진 것으로서, 혼화제 투입장치에 설치된 계량장치의 고장 여부 및 혼화제의 정상적인 투입여부를 즉시 인지할 수 있을 뿐 아니라, 인지와 동시에 혼화제 투입이 자동으로 즉시 차단되도록 하며, 이러한 관리가 매우 용이하게 되는 혼화제 투입불량 방지장치를 제공하는 데 목적이 있다.The present invention has been made to solve the above problems, it is possible to immediately recognize whether the metering device installed in the admixture injector failure and normal input of the admixture, as well as to automatically block the admixture immediately and immediately. And, it is an object of the present invention to provide a device for preventing admixture defects that is very easy to manage.

상기 목적을 달성하기 위하여, 본 발명은 혼화제를 구성하는 조성물들이 각각 별도로 저장되는 저장탱크들을 가지는 저장조와, 상기 저장탱크와 연결되어 저장탱크로부터 배출되는 각각의 조성물들의 중량을 체크하는 1차계량부와, 상기 1차계량부와 연결되어 1차계량부로부터 배출되는 각각의 조성물들의 총중량 체크하는 2차계량부와, 상기 1차계량부에서 체크된 조성물들의 중량 총합이 2차계량부에서 체크된 조성물들의 총중량의 오차범위 내에 들어오는지 판단하여 오차범위에 들지 않을 경우 저장탱크로부터 조성물들의 배출을 정지시키는 제어부를 포함하여 구성됨을 특징으로 한다.In order to achieve the above object, the present invention is a storage tank having a storage tank in which the compositions constituting the admixture are stored separately, and the first weighing unit for checking the weight of each composition connected to the storage tank and discharged from the storage tank And a secondary metering unit connected to the primary metering unit for checking the total weight of the respective compositions discharged from the primary metering unit, and the sum of the weights of the compositions checked in the primary metering unit checked in the secondary metering unit. It is characterized in that it comprises a control unit for stopping the discharge of the composition from the storage tank when the determination does not fall within the error range of the total weight of the composition.

또한, 상기 1차계량부의 계량장치 후방의 배출로에는 저장탱크로부터 분기된 배출유로가 연결되어, 저장탱크 내부로 혼화제가 과투입될 경우, 과투입되는 혼화제 조성물들이 2차계량부에서 계량되게 하여 제어부가 과투입여부를 감지할 수 있도록 할 수 있다.In addition, the discharge passage branched from the storage tank is connected to the discharge path behind the metering device of the primary metering unit, so that when the admixture is over-injected into the storage tank, the admixture composition to be over-injected is metered in the secondary metering unit. The control unit may be able to detect whether the over-injection.

본 발명의 특징과 이점들은 첨부된 도면 및 이에 의거한 아래의 상세한 설명에 의해 명확해진다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.The features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

도 2에 도시된 바와 같이, 본 발명에 따른 혼화제 투입불량 방지장치는 혼화제를 구성하는 조성물들이 각각 별도로 저장되는 저장탱크(110)들을 가지는 저장조 (100)와, 상기 저장탱크(110)와 연결되어 저장탱크(110)로부터 배출되는 각각의 조성물들의 중량을 체크하는 1차계량부(200)와, 1차계량부(200)로부터 배출되는 각 조성물들을 총중량을 체크하는 2차계량부(300)와, 상기 1차계량부(200)와 2차계량부(300)의 중량치를 비교하여 오차범위를 벗어난 경우, 저장탱크(110)로부터의 조성물 배출을 정지시키는 제어부(미도시)를 포함하여 이루어진다.As shown in FIG. 2, the admixture preventing device for preventing misfeeding according to the present invention is connected to the storage tank 100 and the storage tank 110 having the storage tanks 110 in which the compositions constituting the admixture are stored separately, respectively. A primary metering unit 200 for checking the weight of each composition discharged from the storage tank 110, a secondary metering unit 300 for checking the total weight of each composition discharged from the primary metering unit 200, and In addition, the control unit (not shown) is configured to stop discharging the composition from the storage tank 110 when it is out of an error range by comparing the weights of the first and second weighing units 200 and 300.

상기 저장조(100)는 복수의 저장탱크(110)들로 이루어져 구성되며, 각 저장탱크(110)에는 혼화제를 구성하는 조성물들(이하 "혼화제"라 함)이 분쇄 및 교반과정을 거쳐 액상으로 각각 저장된다. 각 저장탱크(110)의 하부에는 저장된 혼화제를 배출시키도록 배출로(120)가 형성되고, 각 저장탱크(110)의 상부에는 저장탱크(110) 내부로의 혼화제 유입을 차단하는 밸브(미도시)가 설치된다.The storage tank 100 is composed of a plurality of storage tanks 110, each of the storage tanks 110, the composition constituting the admixture (hereinafter referred to as "mixing agent") through the grinding and stirring process to each of the liquid phase Stored. A discharge path 120 is formed at a lower portion of each storage tank 110 to discharge the stored admixture, and a valve (not shown) at the upper portion of each storage tank 110 blocks the admixture of the admixture into the storage tank 110. ) Is installed.

그리고 저장탱크(110)의 소정 높이에는 저장탱크(110) 내부로 혼화제가 과투입되는 것을 감지하도록 수위센서(140)가 설치되어 있다. 이 수위센서(140)는 저장탱크(110)로 혼화제가 과투입됨을 감지하고, 이 신호를 상기 제어부로 전송하여 제어부로 하여금 밸브를 차단하여 저장탱크(110)내로 혼화제가 투입되는 것을 막는다.In addition, the water level sensor 140 is installed at a predetermined height of the storage tank 110 to detect that the admixture is excessively injected into the storage tank 110. The water level sensor 140 senses that the admixture is over-injected into the storage tank 110, and transmits this signal to the control unit to prevent the control unit from closing the valve to prevent the admixture into the storage tank 110.

1차계량부(200)는 상기 저장로의 배출로(120)의 일측에 설치되어 상기 배출로(120)를 통해 배출되는 조성물의 중량를 체크하는 계량장치(210)와, 상기 저장조(100)의 배출로(120)와 연결되어 저장조(100)로부터 배출되는 혼화제를 임시로 저장하는 계량조(220)로 구성된다.The primary metering unit 200 is installed on one side of the discharge passage 120 of the storage passage to check the weight of the composition discharged through the discharge passage 120 and 210 of the storage tank 100 It is connected to the discharge path 120 is composed of a metering tank 220 for temporarily storing the admixture discharged from the storage tank (100).

상기 계량조(220)의 하부에는 저장된 혼화제가 방출되도록 배출로(230)가 연 결된다.The discharge path 230 is connected to the lower portion of the metering tank 220 so that the stored admixture is released.

상기 계량장치(210)는 특별히 한정될 필요는 없다. 예컨대, 외부로부터 가해지는 중량에 비례하여 탄성 변형하는 전기저항변형게이지를 통해 가해지는 중량을 전압으로 변환시켜 측정대상물의 중량를 정밀하게 계량할 수 있도록 된 로드셀이 적당하다.The metering device 210 need not be particularly limited. For example, a load cell capable of precisely measuring the weight of a measurement object by converting the weight applied through an electrical resistance strain gauge that elastically deforms in proportion to the weight applied from the outside to a voltage is suitable.

상기 1차계량부(200)를 통해 측정된 결과는 제어부를 통해 입력되고 이 결과는 작업자가 인지할 수 있도록 조작반(미도시)으로 출력된다. 따라서, 작업자는 상기 조작반을 통해 저장탱크(110)로부터 혼화제가 정확한 양으로 배출되는지를 실시간으로 파악할 수 있다.The result measured by the primary weighing unit 200 is input through the control unit and the result is output to an operation panel (not shown) so that an operator can recognize it. Therefore, the operator can determine in real time whether the admixture is discharged from the storage tank 110 in the correct amount through the operation panel.

2차계량부(300)는 상기 계량조(220)의 배출로(230) 일측에 설치되어 상기 배출로(230)를 통해 배출되는 혼화제의 중량을 체크하는 보조계량장치(310)와, 상기 계량조(220)의 배출로(230) 하단에 연결되어 계량조(220)로부터 배출되는 혼화제를 한군데로 취합하는 호퍼(320)로 구성된다.The secondary metering unit 300 is installed on one side of the discharge path 230 of the metering tank 220 and the auxiliary metering device 310 to check the weight of the admixture discharged through the discharge path 230, and the measurement The hopper 320 is connected to the lower end of the discharge path 230 of the tank 220 and collects the admixture discharged from the metering tank 220 into one place.

상기 호퍼(320)의 하부에는 취합된 혼화제가 콘크리트와 혼합되는 다음 공정으로 투입될 수 있도록 배출로(330)가 연결되며, 이 배출로(330)에는 호퍼(320)로부터 혼화제의 배출을 차단하는 밸브(340)가 설치된다. A discharge path 330 is connected to the lower portion of the hopper 320 so that the mixed admixture is introduced into the next process of mixing with concrete, and the discharge path 330 blocks the discharge of the admixture from the hopper 320. The valve 340 is installed.

상기 보조계량장치(310)는 1차계량부(200)의 계량장치(210)와 구성이 동일하므로 여기서의 상세한 설명은 생략하기로 한다.Since the auxiliary metering device 310 has the same configuration as the metering device 210 of the primary metering unit 200, a detailed description thereof will be omitted.

한편, 상기 1차계량부(200)와 2차계량부(300)는 측정한 계량값을 제어부로 전달한다. 상기 제어부는 1차계량부(200)의 계량장치(210)에서 측정한 계량값이 미 리 설정된 오차범위를 만족하지 않을 경우 밸브(240)를 막아 혼화제의 배출을 중지시킴과 동시에 경보장치 등을 작동시켜 작업자에게 혼화제의 투입불량을 인지시킨다.On the other hand, the primary measuring unit 200 and the secondary measuring unit 300 transmits the measured value measured to the control unit. The controller stops the discharge of admixture by stopping the valve 240 when the measured value measured by the metering device 210 of the primary weighing unit 200 does not satisfy the preset error range, It is activated to inform the worker of the poor input of admixture.

만일, 1차계량부(200)에서 측정된 계량값이 오차범위 내에 있을 경우에는 2차계량부(300)측으로 배출시킨다. 이 경우, 1차계량부(200)를 통과한 혼화제는 모두 2차계량부(300)의 호퍼(320)에 모이게 되는데, 여기서 보조계량장치(310)에 의해 혼화제의 총량이 계량된다. 계량이 완료되면, 상기 보조계량장치(310)는 이 계량값을 제어부로 전달한다.If the measured value measured by the primary weighing unit 200 is within an error range, the measured value is discharged to the secondary weighing unit 300. In this case, all the admixtures passing through the primary metering unit 200 are collected in the hopper 320 of the secondary metering unit 300, where the total amount of the admixtures is measured by the auxiliary metering device 310. When the weighing is completed, the auxiliary weighing device 310 transmits this weighing value to the controller.

그리고 제어부는 1차계량부(200)에서 계량된 혼화제의 중량 총합이 2차계량부(300)에서 체크된 혼화제의 총중량의 오차범위 내에 들어오는지 판단한다. 그 결과, 미리 설정된 오차범위를 만족할 경우에는 2차계량부(300)의 호퍼(320)에 모인 혼화제를 배출로(330)를 통해 다음 공정으로 배출시킨다.The controller determines whether the total weight of the admixtures measured in the primary metering unit 200 falls within an error range of the total weight of the admixtures checked in the secondary metering unit 300. As a result, when the preset error range is satisfied, the admixture collected in the hopper 320 of the secondary metering unit 300 is discharged to the next process through the discharge path 330.

그러나, 미리 설정된 오차범위에 들지 않을 경우, 상기 2차계량부(300)의 밸브(340)을 막아 호퍼(320)에 모인 혼화제가 배출되지 않도록 한다. 여기서, 상기 제어부는 저장탱크(110)의 배출로(120)에 설치된 밸브를 막아 저장탱크(110)로부터 혼화제들이 더 이상 배출되지 않도록 하거나 1차계량부의 밸브(240)를 제어하여 2차계량부(300)측으로 혼화제가 배출되지 않도록 차단할 수도 있다.However, if not within the preset error range, the valve 340 of the secondary metering unit 300 is blocked to prevent the admixture collected in the hopper 320 from being discharged. Here, the control unit blocks the valve installed in the discharge path 120 of the storage tank 110 so that admixtures are no longer discharged from the storage tank 110 or by controlling the valve 240 of the primary metering unit. It may be blocked to prevent the admixture is discharged to the (300) side.

한편, 상기 제어부에는 경보장치(미도시)가 더 연결될 수도 있다. 이 경우, 상기 제어부는 저장탱크(110)로부터 혼화제의 배출을 정지시킴과 동시에 경보를 발생시켜 작업자에게 혼화제의 공급이상 유무를 즉시 알림으로써 신속한 후속조치를 유도할 수 있다.Meanwhile, an alarm device (not shown) may be further connected to the controller. In this case, the control unit may stop the discharge of the admixture from the storage tank 110 and at the same time generate an alarm to promptly inform the operator of the supply or absence of admixtures to induce rapid follow-up.

또한, 상기 저장탱크(110)의 일측에는 배출유로(400)가 분기되어 1차계량부(200)의 계량장치(210) 후방의 배출로(120)에 연결된다. 이 배출유로(400)는 저장탱크(110)에 설치된 수위센서(140)보다 높게 설치되어, 상기 저장탱크(110)로 혼화제가 과투입될 경우, 과투입되는 혼화제를 계량장치(210)의 후방측으로 배출되도록 유도함으로써 2차계량부(300)의 보조계량장치(310)로 하여금 상기 저장탱크(110)로 과투입되는 혼화제가 함께 계량되도록 한다.In addition, the discharge passage 400 is branched to one side of the storage tank 110 and is connected to the discharge passage 120 behind the metering device 210 of the primary metering unit 200. The discharge flow path 400 is installed higher than the water level sensor 140 installed in the storage tank 110, when the admixture is over-injected into the storage tank 110, the admixture to be over-injected into the rear of the metering device 210 The secondary metering unit 310 of the secondary metering unit 300 is guided to be discharged to the side to allow the admixture to be over-injected into the storage tank 110 to be metered together.

상기와 같이 구성된 본 발명의 혼화제 투입불량 방지장치에 의하면, 제어부가 1차계량부(200)와 2차계량부(300)의 중량차를 판단하여 혼화제 투입의 이상유무를 판단하도록 되어 있기 때문에, 1차계량부(200)측에 설치된 계량장치(210)가 정상적으로 작동하지 않아 혼화제 투입에 이상이 발생되었을 경우, 제어부가 경보장치를 작동시켜 작업자가 이를 즉시 인지할 수 있다. 뿐만 아니라, 저장탱크(110) 및 제1, 2차계량부(200,300)에 설치된 밸브(240,340)를 막아 해당 배출로(120,230,330)를 통해 혼화제가 유입되거나 배출되는 것을 즉시 차단하므로, 종래와 같이 고장발생 여부를 작업자가 즉시 인지하지 못해 작업자가 이를 인지하고 후속조치를 취할 때까지 상당량의 콘크리트가 불량으로 출하되는 등의 문제를 해결할 수 있다.According to the admixture preventing device of the admixture of the present invention configured as described above, since the control unit determines the weight difference between the primary and the secondary weighing unit 200, 300 is determined whether there is an abnormality of the admixture, When the metering device 210 installed on the primary weighing unit 200 does not operate normally and an abnormality occurs in the admixture, the controller may operate the alarm device to immediately recognize the operator. In addition, by blocking the valves 240 and 340 installed in the storage tank 110 and the first and second measurement units 200 and 300, the admixtures are immediately blocked through the corresponding discharge paths 120, 230, and 330, and thus fail. It is possible to solve the problem such that a considerable amount of concrete is shipped in bad condition until the worker recognizes it and immediately takes further action.

또한 이러한 동작이 제어부에 의해 일괄적으로 이루어지므로 작업자가 계량장치의 이상 유무 및 혼화제 투입이 원활하게 이루어지고 있는지 항상 주시할 필요가 없게 되므로 관리측면에서 매우 용이하다.In addition, since the operation is performed in a batch by the control unit, it is very easy in terms of management since the operator does not have to always keep an eye on whether there is an abnormality of the metering device and whether the admixture is smoothly made.

한편, 본 발명에 따르면 저장탱크(110)에 설치된 수위센서(140)가 정상적인 작동을 하지 못할 경우에도 제어부가 이를 즉시 인지하여 혼화제가 저장탱크(110)로 과투입되는 것을 막을 수 있다.Meanwhile, according to the present invention, even when the water level sensor 140 installed in the storage tank 110 does not operate normally, the controller immediately recognizes this and prevents the admixture from being over-injected into the storage tank 110.

즉, 각 저장탱크(110)에 설치된 수위센서(140)가 고장이 날 경우, 저장탱크(110)로 혼화제가 계속 투입되는데, 저장탱크(110) 내의 혼화제 수위가 배출유로(400)의 설치높이에 이르게 되면, 혼화제가 배출유로(400)를 통해 2차계량부(300)측으로 흘러 넘치게 된다. 배출로(230)측으로 유입되는 혼화제는 계량조(220)를 거쳐 배출로(230)를 통해 배출되는데, 이 과정에서 이 배출로(230)에 설치된 2차계량부(300)의 보조계량장치(310)가 정상치보다 큰 중량을 감지하게 되고, 혼화제 투입에 이상이 있음을 판단한 제어부가 밸브(340)를 차단하고 경보장치를 작동시키게 된다.That is, when the water level sensor 140 installed in each storage tank 110 is broken, the admixture is continuously added to the storage tank 110, the admixture level in the storage tank 110 is the installation height of the discharge passage 400 When it reaches, the admixture flows to the secondary metering unit 300 through the discharge passage 400. The admixture flowing into the discharge path 230 is discharged through the discharge path 230 through the metering tank 220, and in this process, an auxiliary metering device of the secondary metering unit 300 installed in the discharge path 230 ( 310 detects the weight greater than the normal value, the control unit determines that there is an error in the admixture admixture shuts off the valve 340 and operates the alarm device.

상기한 바와 같이 본 발명의 혼화제 투입불량 방지장치에 따르면, 1차계량부와 2차계량부를 통해 각 저장탱크로부터 배출되는 혼화제의 중량을 이중으로 측정하고 그 중량차를 판단하여 혼화제 투입의 이상유무를 판단하도록 되어 있기 때문에 1차계량부측에 설치된 계량장치가 정상적으로 작동하지 않을 경우, 이를 즉각적 감지할 수 있으며, 이와 동시에 혼화제가 더 이상 투입되지 못하도록 자동차단하여 상당량의 콘크리트가 불량으로 출하되는 것을 방지할 수 있는 효과가 있다.As described above, according to the admixture preventing device of the admixture of the present invention, by measuring the weight of the admixture discharged from each storage tank through the first and second weighing unit double and determine the weight difference, whether there is an abnormality of the admixture Since the weighing device installed on the primary weighing unit does not operate normally, it can be detected immediately, and at the same time, it prevents a considerable amount of concrete from being shipped as defective by blocking the admixture from entering any more. It can work.

또한, 저장탱크로부터 배출유로를 분기시켜 저장탱크에 설치된 수위센서가 정상적인 작동을 하지 못할 경우, 제어부가 이를 감지하여 혼화제의 투입을 차단함 으로써 혼화제가 저장탱크 내부로 과투입되는 것을 막을 수 있다.In addition, when the water level sensor installed in the storage tank by branching the discharge flow path from the storage tank does not operate normally, the control unit detects this to block the input of the admixture can prevent the admixture is over-injected into the storage tank.
