Description

곡물포장용 호퍼 개폐장치{Opening and shutting equipment of Hopper}{Opening and shutting equipment of Hopper}

본 발명은 곡물 포장용 호퍼 개폐장치에 관한 것으로, 더욱 바람직하게는 수확한 곡물을 호퍼에 수장한 후, 호퍼에 수장된 곡물을 하부에 형성된 곡물유도함의 배출구를 통해 배출되는 곡물의 양을 개폐판으로 1차, 2차 조절해가면서 배출하게 하여 계량을 정확하게 한 후 포장할 수 있도록 하기 위한 것이다.
The present invention relates to a hopper opening / closing apparatus for packing cereals, more preferably, after harvested cereals are stored in a hopper, the amount of cereals discharged through the outlet of the grain guiding basin formed in the lower portion of the hopper is used as an open / It is intended to make the weighing precisely and then to be packed so that it can be discharged while adjusting the 1st and 2nd order.

콤바인으로 벼를 수확할 때 콤바인에서 탈곡된 곡물은 콤바인에 구비된 호퍼에 저장되거나, 콤바인과 함께 별도의 곡물수송차량이 이동하면서 콤바인에서 수확한 곡물을 담아서 이동하도록 하고 있다.When harvesting rice with a combine, grains harvested from the combine are stored in a hopper provided in the combine, or a separate grain transportation vehicle is moved along with the combine, so that the grains harvested from the combine are transported.

상기와 같이 수확한 쌀과 같은 곡물을 일정량 종이 포대 등의 포장백(일반적으로 톤백 사용)에 담아서 포장한 다음, 도정공장 등으로 통해 소형단위로 포장되어 마트나 슈퍼마켓 등에서 판매하게 된다.Grains such as rice harvested as described above are packed in a packing bag such as a paper bag (generally used as a ton bag), packed in a small unit through a corrugating factory, and then sold in a mart or a supermarket.

한편, 각 농가에서 건조장치에 의해 건조된 곡물을 포장시에는 일정량 곡물을 포장백에 담아서 포장하는 것이 필요한데, 곡물은 호퍼에 수장하고 호퍼 아래에는 포장백을 저울 위에 올려 놓은 다음, 배출구의 개폐판을 열어 곡물이 쏟아지게 하고 포장백에 담긴 곡물이 일정중량이 되면 개폐판을 닫게 된다.On the other hand, it is necessary to pack a certain amount of grains in a packaging bag when packaging the grains dried by the drying apparatus in each farmhouse. The grains are stored in the hopper, the packaging bag is placed on the bottom of the hopper, And the grain is poured. When the grains contained in the packing bag reach a certain weight, the opening and closing plate is closed.

상기와 같은 방법으로 곡물을 계량기로 배출하여 계량해서 포장할 수 있도록 하는 실용신안 출원 제20-2005-0010334호로 출원된 곡물계량 작업기가 안출되어 있다. 상기한 곡물계량 작업기의 개폐장치는 호퍼로 투입된 곡물을 호퍼의 하부에 형성된 배출구를 통해 배출하도록 함과 동시에, 일정량 배출되면 개폐판이 배출구를 폐쇄하여 곡물의 정량 여부를 측정한 다음 정량이 미달 되면 개폐판을 열어 다시 곡물을 배출하여 정량을 채우도록 하는 구성을 갖는다..
There has been found a grain weighing machine applied with a method of discharging grains to a weigher and weighing them so as to be packaged in the same manner as described in the Utility Model Application No. 20-2005-0010334. The opening and closing device of the grain weighing machine described above allows the grains put into the hopper to be discharged through a discharge port formed in the lower part of the hopper, and when the discharge amount of the grain is exhausted, the opening and closing plate closes the outlet to measure whether or not the grain is quantified. And then the plate is opened and the grain is discharged again to fill the metered amount.

그러나 상기와 같은 종래의 곡물포장용 호퍼 개폐장치는 호퍼에 수장된 곡물을 하나의 개폐판으로 배출구를 차단하게 되어 곡물의 배출량 조절이 매우 곤란한 단점을 갖는다. 또한 대개의 곡물 포장용 호퍼는 신속한 포장을 위해 대량의 곡물이 배출되도록 배출구를 크게 형성하므로 잠깐 여닫는 순간에 엄청난 양의 곡물이 그대로 쏟아지게 되어 배출되는 곡물의 양을 쉽사리 조절할 수 없는 문제점을 갖는 것이다.However, the above-described conventional hopper opening / closing apparatus for packing cereals has a disadvantage in that it is very difficult to control the discharge amount of grains because the outlet opening is blocked by one opening and closing plate of the grains stored in the hopper. Also, since most of the hopper for packing a grain forms a large discharge port for discharging a large amount of grain for rapid packaging, a huge amount of grain is poured at the moment of opening and closing, and the amount of grain to be discharged can not be easily adjusted.

따라서 종래의 곡물 포장용 호퍼는 곡물이 너무 많이 배출되면 배출된 곡물을 포장백(톤백)으로 부터 덜어내고 너무 적게 배출되면 미리 퍼놓은 곡물을 바가지 등으로 정량이 될 때까지 채우게 되어 곡물의 정량을 측정함에 있어 시간이 많이 걸리고, 이로 인해 작업능률을 현저히 떨어지는 단점을 갖는 것이다.Therefore, the conventional hopper for packing cereals has a problem in that when the grains are discharged too much, the discharged grains are taken out from the packing bag (ton bag), and when too little is discharged, It takes a lot of time to work, and it has a disadvantage that the work efficiency is remarkably deteriorated.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출한 것으로, 수확한 곡물을 포장하기 위해 계량기로 곡물을 배출하여 계량할 때, 호퍼의 하부에 형성된 곡물유도함의 배출구로 배출되는 곡물의 양을 배출구를 개폐하는 개폐판을 소량으로 곡물배출이 가능한 1차 개폐판과 대량으로 곡물배출이 가능한 2차 개폐판으로 에 걸쳐 개폐하도록 하되, 상기 개폐판들은 솔레노이드의 구동에 의해 개폐되고, 상기 솔레노이드는 제어장치(미도시)에 의해 미리 설정된 저울의 무게에 맞춰 작동하도록 함으로써 신속하게 곡물의 정량을 포장할 수 있도록 함을 특징으로 한다.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an apparatus and a method for discharging cereals to be discharged to a discharge port of a grain induction box formed at a lower portion of a hopper, Closing plate for opening and closing the opening and closing plate through a first opening and closing plate capable of discharging a small amount of grain and a second opening and closing plate capable of discharging a large amount of grain, the opening and closing plates being opened and closed by driving of the solenoid, (Not shown) so as to be able to quickly pack the quantities of the grain.

상기와 같은 특징을 갖는 본 발명은 논이나 밭에서 수확한 쌀이나 잡곡 등을 일정량씩 계량하여 포장하고자 할 때, 호퍼에 수장된 곡물을 하부의 곡물유도함에 형성된 배출구를 통해 배출되는 곡물의 양을 소량 조절이 가능한 1차 개폐판 및 대량 조절이 가능한 2차 개폐판으로 개폐하면서 조절할 수 있기 때문에, 곡물의 계량을 빠르고 정확하게 할 수 있어 작업능률을 향상시킬 수 있는 것이다.The present invention having such characteristics as described above is characterized in that when a rice or grain crop harvested in a rice field or a field is weighed and packed in a predetermined amount, the amount of grain discharged through the outlet formed in the lower grain- It is possible to control the opening and closing of the first opening / closing plate with a small amount of control and the second opening / closing plate capable of mass control, so that the weighing of the grain can be performed quickly and accurately, thereby improving the working efficiency.

또한 본 발명은 1차 개폐판과 2차 개폐판을 솔레노이드의 구동에 의해 개폐되도록 하되, 상기 솔레노이드는 제어장치에 의해 미리 설정된 저울의 무게에 맞춰 작동하도록 함으로써 신속하게 곡물의 정량을 포장할 수 있는 매우 유용한 발명인 것이다.

본 발명은 도 1 및 도 2에 나타내는 바와 같이, 호퍼(10)의 하부에 장착되어 곡물을 배출구(21)로 배출할 수 있도록 형성하는 곡물유도함(20)과 상기 배출구(21)를 개폐하여 곡물의 양을 배출량을 조절할 수 있도록 하는 개폐판(30)을 구비하는 곡물포장용 호퍼 개폐장치에 있어서 1 and 2, the present invention relates to a grain guiding box 20 mounted on a lower portion of a hopper 10 so as to be capable of discharging grain to a discharge port 21, And an opening / closing plate (30) for controlling the discharge amount of the hopper opening / closing device

상기 배출구(21)를 1차 개폐하여 곡물의 양을 조절할 수 있도록 배출공(31)이 천공된 1차 개폐판(30)과,A primary opening and closing plate 30 having a discharge hole 31 formed therein for opening and closing the discharge opening 21 so as to adjust the amount of grain,

상기 1차 개폐판(30)의 저면에 장착되어 배출공(31)을 개폐하도록 형성된 2차 개폐판(40)과,A secondary opening / closing plate 40 mounted on the bottom surface of the primary opening / closing plate 30 and configured to open / close the discharge hole 31,

상기 1차 및 2차 개폐판(30)(40)의 일측에 장착되어 개폐를 제어하는 제 1 및 제 2 솔레노이드(50)(60)로 구성된다.And first and second solenoids 50 and 60 mounted on one side of the first and second opening and closing plates 30 and 40 to control opening and closing.

이때 상기 1차 개폐판과 2차 개폐판은 제1 및 제2 솔레노이드(50)(60)에 의해 개폐되고, 상기 제1 및 제2 솔레노이드(50)(60)는 제어장치(100)에 의해 구동되되, 상기 제어장치(100)는 저울(110)에 미리 설정해둔 중량에 의해 제 1 및 제 2 솔레노이드(50)(60)를 각각 구동하도록 구성된다.
The first and second solenoids 50 and 60 are opened and closed by the first and second solenoids 50 and 60 and the first and second solenoids 50 and 60 are controlled by the controller 100 The controller 100 is configured to drive the first and second solenoids 50 and 60, respectively, according to the weight set in advance on the scale 110.

상기와 같은 구성을 갖는 본 발명에 따른 곡물포장용 호퍼 개폐장치의 구성을 보다 구체적으로 설명하고자 한다.The construction of the hopper opening / closing apparatus for packing cereals according to the present invention having the above-described structure will be described in more detail.

도 1 및 도 2에 나타내는 바와 같이, 논이나 밭에서 수확한 곡물을 건조한 다음 일정량씩 계량하여 포장할 수 있도록 하기 위한 본 발명의 구성은, 수확한 곡물을 수장할 수 있는 호퍼(10)가 형성된다. 그리고 호퍼(10)의 하부에는 곡물을 배출하는 배출구(21)가 형성된 곡물 유도함(20)이 결합된다. 상기 호퍼(10)의 하부와 곡물유도함(20)의 상부에는 각각 플랜지(11)(22)를 형성하여 체결구(80)로 일체가 되도록 결합한다.As shown in Figs. 1 and 2, the present invention is configured to dry grains harvested in paddy fields or fields and then weighed and packed by a predetermined amount. The hopper 10 capable of storing harvested grains is formed do. In the lower part of the hopper 10, a grain guide box 20 having an outlet 21 for discharging grain is connected. Flanges 11 and 22 are formed on the lower portion of the hopper 10 and the upper portion of the grain guiding box 20 and are coupled together by the fastener 80.

그리고 곡물유도함(20)의 배출구(21)에는 상기 배출구(21)를 1차 개폐하는 1차 개폐판(30)과 2차 개폐하는 2차 개폐판(40)이 형성된다. 이때 상기 1차 개폐판(30)과 2차 개폐판(40)은 양측을 절곡하여 절곡편(32,41)이 형성되게 한다. 따라서 단면이 ㄷ자형으로 형성되어 지고, 상기 절곡편(32,41)은 곡물유도함(20)의 양측에 축(軸) 기능을 하는 핀(33)에 의해 회전가능토록 결합되도록 한다. The outlet 21 of the grain guiding box 20 is formed with a primary opening and closing plate 30 for opening and closing the outlet 21 and a secondary opening and closing plate 40 for opening and closing the outlet 21. At this time, both the first opening and closing plate 30 and the second opening and closing plate 40 are bent so that the bent pieces 32 and 41 are formed. Thus, the bent portions 32 and 41 are rotatably coupled to both sides of the grain guide box 20 by a pin 33 functioning as an axis.

물론 상기 개폐판(30,40)들은 핀을 중심으로 회전할 수 있도록 하기 위해 일측의 절곡편(32,41) 상단이 각 솔레노이드(50,60) 로드(51.61) 끝단에 결합되도록 구성된다. Of course, the opening / closing plates 30 and 40 are configured so that the upper ends of the bending pieces 32 and 41 of one side are coupled to the ends of the rods 51 and 51 of the solenoids 50 and 60 so as to rotate around the pins.

상기 1차 개폐판(30)의 저면에는 2차 개폐판(40)이 간극을 두고 형성되는데 이는 1차 개폐판(30)과 2차 개폐판(40)이 여닫힘에 있어 서로 간섭되는 것을 방지하기 위한 것이다.The second opening and closing plate 40 is formed on the bottom surface of the primary opening and closing plate 30 with a gap therebetween so as to prevent the first opening and closing plate 30 and the second opening and closing plate 40 from interfering with each other .

또한 상기 1차 개폐판(30)의 절곡편(32)과 2차 개폐판(40)의 절곡편(41)은 서로 대향하는 다른 방향에 설치하여 제 1솔레노이드(50)와 제 2솔레노이드(60)를 작동함에 있어 간섭되지 않도록 한다.The bending piece 32 of the primary opening and closing plate 30 and the bending piece 41 of the secondary opening and closing plate 40 are provided in opposite directions opposite to each other and the first solenoid 50 and the second solenoid 60 So as not to be interfered with.

상기 제 1솔레노이드(50)와 제 2솔레노이드(60) 로드(51.61) 일단이 절곡편(32) 상단에 연결되도록 하는 이유는 1차 및 2차 개폐판(30)(40)이 핀(33) 아래에 위치해 있고, 또 상기 핀(33)을 중심으로 회전운동을 하는 구조여서 핀(33)보다 상부에서 각 절곡편(32,41)을 잡아 당기거나 미는 구성을 가져야 하기 때문이다. The reason for connecting one end of the first solenoid 50 and the second solenoid 60 rod 51.61 to the upper end of the bending piece 32 is that the first and second opening and closing plates 30, And has a structure that rotates about the pin 33 so that the bending pieces 32 and 41 are pulled or pushed from above the pin 33. [

따라서 상기 제 1솔레노이드(50)와 제 2솔레노이드(60)의 로드 끝단에는 탄성스프링(70)(71)을 각각 장착하여 솔레노이드 내부 전자석의 자력에 의해 로드(51.61)를 견인하였다가 자력을 상실하는 경우 탄성력에 의해 탄성스프링(70)(71) 방향으로 당겨지도록 한다.
Therefore, elastic springs 70 and 71 are attached to the rod ends of the first solenoid 50 and the second solenoid 60, respectively, and the rod 51.61 is pulled by the magnetic force of the electromagnet inside the solenoid, It is pulled in the direction of the elastic spring 70 (71) by the elastic force.

상기와 같이 구성된 본 발명의 작동상태를 도 3 및 도 4에 의거하여 설명하면 다음과 같다.The operation state of the present invention configured as described above will be described with reference to FIGS. 3 and 4. FIG.

수확한 곡물을 일정량씩 계량하기 위하여 호퍼(10)에 곡물을 수장한다. 상기 호퍼(10)에 수장된 곡물은 호퍼(10)의 하부에 장착된 곡물유도함(20)으로 유도되어 배출구(21)로 배출되게 구성한다.The grains are stored in the hopper (10) to weigh the harvested grains one by one. The grain stored in the hopper 10 is guided to the grain guiding box 20 mounted on the lower part of the hopper 10 and is discharged to the discharge port 21.

이때 곡물 유도함(20)의 하부에서 곡물을 유도하기 위한 계량대로 곡물이 배출되도록 하고자 할 때, 먼저 제 1솔레노이드(50)와 제 2솔레노이드(60)를 동시에 작동시킨다. 따라서 제 1솔레노이드(50)와 제 2솔레노이드(60)가 작동되면 각 솔레노이드의 로드는 1차 개폐판(30)과 2차 개폐판(40)의 절곡편(32)(41)을 잡아당기게 되고 이로 인해 1차 개폐판(30)과 2차 개폐판(40)은 핀을 중심으로 회전하게 되면서 뒤로 젖혀지게 되고 결국 곡물 유도함(20)의 배출구(21)는 완전히 개방된 상태가 된다.At this time, when it is desired to discharge the grain according to the metering for guiding the grain from the lower part of the grain guide box 20, the first solenoid 50 and the second solenoid 60 are operated simultaneously. Therefore, when the first solenoid 50 and the second solenoid 60 are operated, the rod of each solenoid pulls the bending piece 32 (41) of the first opening / closing plate 30 and the second opening / closing plate 40 As a result, the primary open / close board 30 and the secondary open / close board 40 are rotated about the pin and are turned backward, so that the outlet 21 of the grain guide box 20 is completely opened.

따라서 많은 양의 곡물이 배출구(21)를 통해 배출되어 지고, 순식간에 포장백에 곡물이 채워지게 된다. Therefore, a large amount of grain is discharged through the discharge port 21, and the packing bag is instantly filled with grains.

상기와 같은 작동에 의해 배출구(21)를 통해 곡물을 계량하고자 하는 무게만큼 근접하여 배출되면, 정확한 계량 조절을 위하여 제 1솔레노이드(50)의 전원을 차단한다. 그러면 제 1솔레노이드(50)의 로드(51)는 스프링(71)의 탄성력에 의해 복원되면서 1차 개폐판(30)이 솔레노이드 견인시와는 반대방향으로 회전하면서 곡물유도함(20)의 배출구(21)를 폐쇄하게 된다.When the grains are discharged as close to the weight to be weighed through the discharge port 21 by the above operation, the power of the first solenoid 50 is cut off for accurate metering control. The rod 51 of the first solenoid 50 is restored by the elastic force of the spring 71 so that the primary opening and closing plate 30 rotates in a direction opposite to that at the time of pulling the solenoid, ).

그러나 상기 1차 개폐판(30)에는 중간부위에 적은 양이 곡물이 배출되도록 배출공(31)이 천공된 구조이므로 1차 개폐판(30)에 의해 곡물유도함(20)의 배출구(21)를 폐쇄하였다고 하더라도 적은 량의 곡물을 계속해서 배출되고 있는 상태이다.However, since the discharge opening 31 is pierced in the primary opening and closing plate 30 so that a small amount of grain is discharged from the intermediate opening 30, the discharge opening 21 of the grain introducing door 20 is opened by the primary opening and closing plate 30 Even if it is closed, a small amount of grain is continuously being discharged.

따라서 이로 인해 충분한 시간을 두고 정확한 계량이 가능해지고 설정된 무게에 달하는 순간 제 2솔레노이드(60)의 전원을 차단한다. 그러면 제 2솔레노이드(60)의 로드(61) 역시 스프링(70)의 탄성력에 의해 복원되면서 2차 개폐판(40)이 순간적으로 곡물유도함(20)의 배출구(21)를 폐쇄함으로써 더 이상의 곡물은 배출되지 않게 된다. 이때 마지막 곡물이 배출구로 배출될 때 낙차시 가해지는 충격량도 계량기(저울)에 감안하여 세팅함으로써 더욱 정확한 계량이 가능하게 구성할 수도 있다.Therefore, accurate weighing becomes possible with sufficient time, and the power of the second solenoid 60 is cut off as soon as the set weight is reached. Then the rod 61 of the second solenoid 60 is also restored by the elastic force of the spring 70 so that the second opening and closing plate 40 instantaneously closes the outlet 21 of the grain guide box 20, It is not discharged. At this time, when the last grain is discharged to the discharge port, the amount of impact applied at the time of dropping can be set in consideration of the scale (balance), so that more accurate weighing can be made possible.

따라서 본 발명은 곡물을 포장함에 있어 거의 정확한 양의 계량이 가능하게 되고, 이로 인해 종래처럼 너무 많은 양의 곡물이 쏟아져 덜어낸다거나 너무 적은 양의 곡물이 배출되어 부족한 양을 더 채워야 하는 등의 번거로움을 완벽하게 해결할 수 있는 것이다.Therefore, the present invention enables an almost accurate amount of weighing to be carried out in the packaging of cereals, which results in a large amount of grain pouring out or a very small amount of grain being discharged as in the past, It can solve the problem perfectly.

미설명 부호 90은 본 발명의 곡물 수장함(20)의 배출구(21)에 배출되는 곡물을 포장백으로 유도하기 위한 유도관이다.
Reference numeral 90 denotes a guide tube for guiding the grain discharged into the discharge port 21 of the grain storage box 20 of the present invention to the packaging bag.
