本発明は回転ドラムに落下する粉粒体の重量を検出して
、その流量を計測する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for detecting the weight of powder particles falling onto a rotating drum and measuring the flow rate thereof.
従来、一般に使用されるこの種装置では、ベルトスケー

、ベルトの材質によっては食品等の特殊な粉粒体には使
用できない等の欠点があった。Conventionally, this type of device that is commonly used uses a load detector to detect the powder or granular material (load) on the belt using a belt scale or the like, and converts this into an electrical signal to express the flow rate.
However, such a conventional structure requires a relatively complicated mechanism such as a pulley carrier roller or a meandering adjustment device for the conveyor belt, which constitutes the belt conveyor. However, depending on the material of the belt, it cannot be used for special powder or granular materials such as food.
本発明は上記に鑑み、振動コンベアの切出口直下に無羽

装置を提供することが目的であり、以下、図示する一実
施例について本発明を説明する。In view of the above, the present invention provides a rotating drum equipped with radial blades corresponding to the desired layer thickness when no blades or a layer thickness is required directly below the cutting exit of the vibrating conveyor. An object of the present invention is to provide an apparatus for detecting the load of powder and granular material and measuring the flow rate, and the present invention will be described below with reference to an illustrated embodiment.
第１図は本発明の粉粒体の層厚を所望しない場合で、回
転ドラム外周に何の手段も施こされていない言わば基本
的な第１実施例を示すが、１は振動トラフによる供給装
置で、その切出口から粉粒体を排出し、直下に設ける回
転ドラム２に落下させる。Fig. 1 shows a so-called basic first embodiment in which no desired layer thickness of the powder or granular material of the present invention is applied to the outer periphery of the rotating drum. The device discharges the granular material from the cutting port and drops it onto the rotating drum 2 provided directly below.
この回転ドラム２には第１図に例示した層厚を要求しな
い場合のものと、一定の層厚を所望する場合の２通りが
あり、第２図にはその後者を示し、放射状に羽根を取付
杆、羽根と羽根との間に所望の層厚を形成するようにし
たものである。There are two types of rotary drum 2: one that does not require the layer thickness shown in Fig. 1, and one that requires a constant layer thickness. A desired layer thickness is formed between the mounting rod and the blade.
この回転ドラム２の軸芯には、支点３（エツジ）で支え
られたビーム４の端部が結合され、ドラム２上に落下し
た粉粒体の荷重を検出器５に伝達する。The end of a beam 4 supported by a fulcrum 3 (edge) is connected to the axis of the rotating drum 2, and the load of the powder and granular material falling onto the drum 2 is transmitted to the detector 5.
斯して検出された荷重は増幅器６で電気信号に変換され
粉粒体の流量は計測される。The load thus detected is converted into an electrical signal by an amplifier 6, and the flow rate of the powder is measured.
従って、本発明の回転ドラムを使用するこ（ｒｔｃより
、従来型のベルトスケール式流量計にみられるような、
ベルトコンベア機構等による複雑な構成を必要としなく
なる上、回転ドラム２は鋼板にて製作できるので、清潔
をむねとする食品等の特殊な粉粒体にも有効に利用でき
、全く悪影響を及ぼすことがない。Therefore, the use of the rotating drum of the present invention (RTC), as found in conventional belt scale flowmeters,
In addition to eliminating the need for a complex configuration such as a belt conveyor mechanism, the rotary drum 2 can be made of steel plate, so it can be effectively used for special powder and granular materials such as foods that need to be kept clean, without causing any adverse effects. There is no.
従って、本発明は各種粉粒体のあらゆる場合に適用でき
、汎用性の極めて高い割１１］装置を得ることができる
ものである。Therefore, the present invention can be applied to all types of powder and granular materials, and it is possible to obtain an extremely versatile device.
また、今までに述べた第１実施例で示す回転ドラムは、
外周に何の手段も施こされていない円筒形であるため、
粉粒体の層厚を大きくとることはできないが、ドラムを
回転させることにより絶えず新しい重量を求めることが
できる。Furthermore, the rotating drum shown in the first embodiment described above is
Because it is cylindrical with no measures applied to its outer periphery,
Although it is not possible to increase the layer thickness of the powder, new weights can be constantly determined by rotating the drum.
そこで、前述のドラム上で層厚所望の要求を満たすには
第２図で示すようなドラム外周に所望の層厚に相当する
高さの羽根を放射状に設けることにより、極めて容易に
解消することができる。Therefore, in order to satisfy the above-mentioned requirement for the desired layer thickness on the drum, it is extremely easy to solve this problem by providing radial blades with a height corresponding to the desired layer thickness on the outer periphery of the drum as shown in Fig. 2. Can be done.
伺、本発明により粉粒体の実流量をてこの理を応用して
直接的に計測する場合は、次に述べる方法の何れかに求
められることを付記する。However, it should be noted that when the actual flow rate of powder or granular material is directly measured by applying the principle of leverage according to the present invention, one of the following methods is required.
その１は、回転ドラムの回転速度が一定の場合は、増幅
器の出力のみを計測することにより求められ、その２は
、回転ドラムの回転速度が変化する時は、増幅器の出力
と回転ドラムの速度とを乗算することにより求められる
。The first is that when the rotational speed of the rotating drum is constant, it can be obtained by measuring only the output of the amplifier, and the second is that when the rotational speed of the rotating drum changes, it can be obtained by measuring the output of the amplifier and the speed of the rotating drum. It is found by multiplying by.
