Description

[Detailed description of the invention] Industrial application field The present invention is an automatic grain weighing device that fills storage bags with a preset target weight of grains. , it is possible to accurately grasp the accumulation status of grains in storage bags and the storage status of grains in tanks, etc., and also clearly notify the status of weighing completion, making it possible to easily and appropriately carry out weighing and filling work of grains. The present invention relates to a lighting device that does.

Conventional technology Conventionally, a tank equipped with an automatic shutter, a weighing scale that detects the weight of grains filled from the tank into a storage bag, and a weighing value set in advance until the detected value of the weighing scale reaches the set weighing value. An automatic grain weighing device equipped with a control device that closes the automatic shutter when the grain is weighed is disclosed in, for example, Japanese Utility Model Application Publication No. 60-2601, etc.
Already known.

Problems to be solved by the invention In order for automatic grain weighing of this type mentioned above to perform the automatic grain weighing and filling of storage bags smoothly and accurately, the grain must flow out from the tank evenly and without a hitch. is important, and for that purpose, it is necessary to always maintain an appropriate amount of grain stored in the tank, and also always pay attention to whether the grain piled up in the storage bag is almost even. Must.

However, in conventional automatic grain weighers of this type, the grain outlet of the tank is located at the bottom of the tank.
Moreover, since the tank is large and largely covers the grain outlet, the part where the grain flows out from the tank is often in the dark, especially when working indoors or at night. It has been difficult to accurately grasp the state of the grain flowing out of the storage bag and the state of grain accumulation in the storage bag. Additionally, even if the tank is translucent or transparent, dust from the grains will adhere to the inner surface of the tank, making it impossible to accurately determine the storage status of the grains inside unless there is strong lighting from above. It was the actual situation.

In view of these problems, the present invention enables accurate grasping of the flow state of grains being filled from the tank into storage bags and the accumulation state of grains within the storage bags, as well as the ability to see through the inside of approximately the upper half of the tank. Even if the inner surface of the plastic cover becomes cloudy due to the adhesion of dust, the grain storage condition in the tank can be accurately grasped with a relatively weak light source suitable for illuminating the shutter and its surrounding area from any angle. Another object of the present invention is to provide an illumination device that clearly notifies the state of completion of weighing so that weighing and filling of grains can be carried out easily and appropriately.

Means for Solving the Problems The present invention has the following technical means for achieving its purpose. In other words, it consists of a tank equipped with an automatic shutter, a weighing scale that detects the weight of grains filled from the tank into a storage bag, and a weighing value that is set in advance so that the detected value of the weighing scale becomes the set weighing value. In an automatic grain weighing machine equipped with a control device that closes the automatic shutter when the grain reaches the
An illumination lamp comprising a tank, the upper half of which is curved, diffusely reflecting light inward, and a plastic cover that allows the interior to be seen through, illuminating the shutter and its vicinity and transmitting light into the inner surface of the plastic cover of the tank. An illumination device for an automatic grain weighing machine, characterized in that the lighting device comprises a weighing completion notification means for changing the lighting state of the lighting lamp when the detected value of the weighing scale reaches a set weighing value.

By configuring the device in this way, the effect to achieve the above-mentioned object can be obtained.

Function: The upper half of the tank is curved and consists of a plastic cover that diffusely reflects light inside and allows the interior to be seen through.The lighting lamp illuminates the shutter and its surrounding area and also projects light into the tank. Because of this, it is possible to accurately grasp the flow of grain from the tank into the storage bag and the accumulation of grain inside the storage bag. It illuminates the shutter and its surroundings evenly with diffusely reflected light, even if the inner surface of the transparent plastic cover in the upper half of the tank is clouded with dust, and from any angle. With a suitable relatively weak illumination light source, it is possible to accurately grasp the storage status of grains in the tank. Further, when the detected value of the weight scale reaches the set weight value, the lighting state of the illumination light changes, so that it is possible to clearly notify the weighing completion state. Accordingly, the measuring and filling operation of grains can be performed easily and appropriately.

It is being 3 is a hopper for inputting grains, and 4 is an outlet for discharging immature grains and waste grains.
A grain outlet 5 is formed in the lower part of the tank 2, and the grain outlet 5 is equipped with an automatic shutter 6 for opening and closing the outlet. Reference numeral 7 is a solenoid for opening and closing the automatic shutter 6. A weight scale 8 is installed below the tank 2. This weight scale 8 is a load cell scale and detects weight as an electric signal. 9 is a storage bag. A control device 10 is provided on one side of the fried grain sorting section 1 . This control device 10
is equipped with a weighing value setter 11 and a weight value display 12, and is configured to set the weight value to be measured in advance and close the automatic shutter 6 when the weight value detected by the weighing scale 8 reaches the set value. It operates according to the following conditions.

The tank 2 has a lower half composed of a base 13 made of a metal plate or the like, and an almost upper half composed of a semi-transparent plastic cover 14 which is curved and reflects light inward diffusely and whose interior can be seen through. The interior of the tank 2 can be seen through this plastic cover 14. Note that the plastic cover 14 may be transparent, and even in this case, if dust adheres to the inner surface, light rays will be diffusely reflected on the inner surface. An illumination light 15 is provided at the bottom of one side of the base 13 that constitutes the lower half of the tank 2 . This illumination light 15 is connected to the automatic shutter 6
