Description

本発明は、粉体を連続的に吐出して定量供給するための粉体供給装置に関する。 TECHNICAL FIELD The present invention relates to a powder supply device for continuously discharging and supplying a fixed amount of powder.

従来より、漏斗状のホッパーに投入された粉体を、重力を利用して下方に吐出させて供給する粉体供給装置が知られている。この種の粉体供給装置では、粉体が存在する空間の雰囲気の水分によって粉体が固化してしまった場合等には、いわゆるラットホール、ブリッジといった状態が生じ、粉体の供給が滞ってしまうおそれがあった。 2. Description of the Related Art Conventionally, there has been known a powder feeder that discharges and feeds powder put into a funnel-shaped hopper using gravity. In this type of powder feeder, when the powder solidifies due to the moisture in the atmosphere of the space where the powder exists, a so-called rat hole or bridge occurs, which hinders the powder supply. I could have lost it.

そこで、この種の粉体供給装置には、通常、撹拌機構が設けられ、投入された粉体を撹拌することによって、粉体の固化を防止し、供給量の安定化が図られている（例えば、特許文献１参照。）。 Therefore, this type of powder supply device is usually provided with a stirring mechanism, and by stirring the supplied powder, solidification of the powder is prevented and the supply amount is stabilized ( For example, see Patent Document 1.).

特開２０１５－１８９４７１号公報JP 2015-189471 A

特許文献１に記載の粉体供給装置の撹拌機構では、ホッパーの吐出口の内部に挿入された回転軸をモータによって回転させて、その回転軸に取り付けられている回転羽によって粉体を撹拌している。 In the agitating mechanism of the powder feeder described in Patent Document 1, a rotating shaft inserted into the discharge port of the hopper is rotated by a motor, and powder is agitated by rotating blades attached to the rotating shaft. ing.

しかし、特許文献１に記載の撹拌機構は、周面に小型の回転羽を設けた回転軸を回転させるため、ホッパーに対する回転軸の位置が適切でなかった場合や、粉体が固化していた場合等には、回転羽と吐出口の内周面との間に粉体が詰まってしまい、十分な撹拌性能を発揮できず、粉体を安定供給することができないことがある。 However, since the stirring mechanism described in Patent Document 1 rotates a rotating shaft having small rotating blades on its peripheral surface, the position of the rotating shaft with respect to the hopper is not appropriate, and the powder is solidified. In some cases, the powder is clogged between the rotating blades and the inner peripheral surface of the discharge port, so that sufficient stirring performance cannot be exhibited and the powder cannot be supplied stably.

以下、図面を参照して、本発明の実施の形態に係る粉体供給装置について説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A powder feeder according to an embodiment of the present invention will be described below with reference to the drawings.

図１に示すように、粉体供給装置１は、粉体Ｐが投入されるホッパー１１と、ホッパー１１を把持するとともに、ホッパー１１に微振動を加える振動機構１２と、ホッパー１１の内部に配置されている撹拌部材１３とを備えている。 As shown in FIG. 1, the powder feeder 1 includes a hopper 11 into which powder P is introduced, a vibrating mechanism 12 that grips the hopper 11 and applies minute vibrations to the hopper 11, and a vibration mechanism 12 that is arranged inside the hopper 11. A stirring member 13 is provided.

ホッパー１１は、逆円錐形状の容器である粉体投入部１１ａと、粉体投入部１１ａの下方に位置する先端部に連接された筒状の吐出部１１ｂとを有している。ホッパー１１の粉体投入部１１ａに投入された粉体Ｐは、吐出部１１ｂの下方の開口部から順次吐出されて、容器等に供給される。 The hopper 11 has a powder charging portion 11a, which is an inverted cone-shaped container, and a cylindrical discharging portion 11b connected to the tip located below the powder charging portion 11a. The powder P introduced into the powder introduction section 11a of the hopper 11 is sequentially discharged from the lower opening of the discharge section 11b and supplied to a container or the like.

振動機構１２は、ホッパー１１の吐出部１１ｂの上端部（すなわち、粉体投入部１１ａの近傍部分）を把持する把持部１２ａと、振動子によって微振動を発生させる駆動源１２ｂと、駆動源１２ｂで発生した振動を把持部１２ａに伝達するためのアーム部１２ｃとを有している。 The vibrating mechanism 12 includes a gripping portion 12a that grips the upper end portion of the discharge portion 11b of the hopper 11 (that is, a portion near the powder charging portion 11a), a driving source 12b that generates micro-vibrations with a vibrator, and a driving source 12b. and an arm portion 12c for transmitting the vibration generated in to the grip portion 12a.

把持部１２ａは、筒状の部材であり、ホッパー１１の吐出部１１ｂが把持部１２ａに挿入される。
駆動源１２ｂは、内蔵された振動子によって発生した振動を、上下方向の振動としてアーム部１２ｃに伝達する。 The gripping portion 12a is a cylindrical member, and the discharge portion 11b of the hopper 11 is inserted into the gripping portion 12a.
The driving source 12b transmits the vibration generated by the built-in vibrator to the arm portion 12c as vertical vibration.

アーム部１２ｃは、可撓性の素材で構成された棒状の部材である。アーム部１２ｃは、一端部（すなわち、駆動源１２ｂ側の端部）を上下に微振動させた際には、他端部（すなわち、把持部１２ａ側の端部、ひいては、把持部１２ａに把持されているホッパー１１）が上下に微振動する。また、この他端部は、上下振動だけではなく、一端部を中心としてわずかに回動して、左右方向にも微振動する。 The arm portion 12c is a rod-shaped member made of a flexible material. When one end (that is, the end on the drive source 12b side) is slightly vibrated up and down, the arm portion 12c is gripped by the other end (that is, the end on the gripping portion 12a side, and by extension, the gripping portion 12a). The hopper 11) that is being used vibrates finely up and down. In addition, the other end portion not only vibrates vertically, but also rotates slightly around the one end portion and vibrates slightly in the horizontal direction.

撹拌部材１３は、棒状の挿入部１３ａと、挿入部１３ａに対して所定の角度θ１で連接され、粉体投入部１１ａの内周面に沿って配置された攪拌部１３ｂと、撹拌部１３ｂの先端に設けられた偏心部１３ｃとを有している。撹拌部材１３は、挿入部１３ａを下にして、ホッパー１１の吐出部１１ｂに上方から挿入すると、撹拌部１３ｂ（具体的には、撹拌部１３ｂの先端に設けられた偏心部１３ｃ）がホッパー１１の粉体投入部１１ａの内周面に係止される。すなわち、撹拌部材１３の取り付けは、挿入部１３ａを吐出部１１ｂに挿入するという非常に簡易な工程だけで行うことができる。 The stirring member 13 includes a rod-shaped insertion portion 13a, a stirring portion 13b connected to the insertion portion 13a at a predetermined angle θ1, and arranged along the inner peripheral surface of the powder input portion 11a. and an eccentric portion 13c provided at the tip. When the stirring member 13 is inserted into the discharge portion 11b of the hopper 11 from above with the insertion portion 13a facing downward, the stirring portion 13b (specifically, the eccentric portion 13c provided at the tip of the stirring portion 13b) is pushed into the hopper 11. is engaged with the inner peripheral surface of the powder input portion 11a. That is, the attachment of the stirring member 13 can be performed only by a very simple process of inserting the insertion portion 13a into the discharge portion 11b.

挿入部１３ａと撹拌部１３とがなす角度θ１は、ホッパー１１の吐出部１１ｂの内周面と粉体投入部１１ａの内周面とがなす角度θ２とは異なる角度に構成されている。具体的には、角度θ１が角度θ２よりも小さく構成されている。これにより、粉体供給装置１では、ホッパー１１の粉体投入部１１ａの内周面と撹拌部材１３の撹拌部１３ｂの下方側の面との間に、常に所定の間隔が形成される。 The angle θ1 formed between the insertion portion 13a and the stirring portion 13 is different from the angle θ2 formed between the inner peripheral surface of the discharge portion 11b of the hopper 11 and the inner peripheral surface of the powder charging portion 11a. Specifically, the angle θ1 is configured to be smaller than the angle θ2. Thus, in the powder feeder 1, a predetermined gap is always formed between the inner peripheral surface of the powder input portion 11a of the hopper 11 and the lower surface of the stirring portion 13b of the stirring member 13. As shown in FIG.

撹拌部材１３を取り付けた状態で、ホッパー１１に対し振動機構１２から微振動が伝達されると、撹拌部材１３はホッパー１１に対して固定されていないので、その振動によって撹拌部材１３がホッパー１１の内部で微振動しながら挿入部１３ａを軸として回転移動する（図１における矢印参照）。 With the stirring member 13 attached, when micro-vibration is transmitted from the vibrating mechanism 12 to the hopper 11, the stirring member 13 is not fixed to the hopper 11, so the vibration causes the stirring member 13 to move toward the hopper 11. It rotates about the insertion portion 13a while vibrating slightly inside (see the arrow in FIG. 1).

このとき、撹拌部材１３の挿入部１３ａはホッパー１１の吐出部１１ｂに挿入されているので、ホッパー１１に対する撹拌部材１３の位置が大きく変化することがない。 At this time, since the insertion portion 13a of the stirring member 13 is inserted into the discharge portion 11b of the hopper 11, the position of the stirring member 13 with respect to the hopper 11 does not change significantly.

撹拌部材１３が移動している際には、ホッパー１１の内周面と撹拌部材１３の撹拌部１３ｂの隙間に粉体Ｐが順次引き込まれる。仮に粉体が固化していた場合には、粉体投入部１１ａの内周面と撹拌部１３ｂの下方側の面との間で、その固化した粉体Ｐが粉砕されることになる。 While the stirring member 13 is moving, the powder P is sequentially drawn into the gap between the inner peripheral surface of the hopper 11 and the stirring portion 13b of the stirring member 13 . If the powder is solidified, the solidified powder P is pulverized between the inner peripheral surface of the powder input portion 11a and the lower surface of the stirring portion 13b.

偏心部１３ｃは、撹拌部１３ｂよりも重い材料で形成されている。偏心部１３ｃを設けることにより、撹拌部材１３の重心がホッパー１１の外周寄りになり、偏心部１３ｃが粉体投入部１１ａの内周面によって支持されるため、ホッパー１１内の撹拌部材１３の姿勢は、ある程度一定の状態で保たれる。これにより、微振動が伝達された撹拌部材１３の挙動は、ある程度安定したものとなっている。なお、撹拌部材１３全体が十分に重く、その姿勢及び挙動が安定している場合には、偏心部１３ｃは省略してもよい。 The eccentric portion 13c is made of a heavier material than the stirring portion 13b. By providing the eccentric portion 13c, the center of gravity of the stirring member 13 becomes closer to the outer periphery of the hopper 11, and the eccentric portion 13c is supported by the inner peripheral surface of the powder charging portion 11a. is kept constant to some extent. As a result, the behavior of the stirring member 13 to which the minute vibration is transmitted is stabilized to some extent. The eccentric portion 13c may be omitted if the stirring member 13 as a whole is sufficiently heavy and its posture and behavior are stable.

また、撹拌部材１３の挿入部１３ａの下方の先端部は、ホッパー１１の吐出部１１ｂの下方の先端から突出している。これにより、吐出部１１ｂから吐出された粉体Ｐは、挿入部１３ａによって導かれ、拡散することなく下方に供給される。なお、粉体Ｐの粒径が十分に大きい場合等、拡散の防止をあまり考慮しなくてもよい場合等には、挿入部１３ａの先端部が、吐出部１１ｂの内部に位置していてもよい。 The lower tip of the insertion portion 13 a of the stirring member 13 protrudes from the lower tip of the discharge portion 11 b of the hopper 11 . As a result, the powder P ejected from the ejection portion 11b is guided by the insertion portion 13a and supplied downward without being diffused. In addition, when the particle size of the powder P is sufficiently large or when it is not necessary to consider the prevention of diffusion, even if the tip of the insertion portion 13a is positioned inside the ejection portion 11b, good.

このように、本発明の粉体供給装置の撹拌部材１３は、ホッパー１１の吐出部１１ｂに挿入されている棒状の挿入部１３ａと、挿入部１３ａに対し所定の角度θ１をなして延設された撹拌部１３ｂを有している。そのため、挿入部１３ａを下にしてホッパー１１に挿入することで、撹拌部１３ｂホッパーの粉体投入部の内周面に係止されるため、非常に簡易な取り付け方法となっている。 As described above, the stirring member 13 of the powder feeder of the present invention has a rod-like insertion portion 13a inserted into the discharge portion 11b of the hopper 11 and extends at a predetermined angle θ1 with respect to the insertion portion 13a. It has a stirring part 13b. Therefore, by inserting the inserting portion 13a into the hopper 11 with the inserting portion 13a facing downward, the stirring portion 13b is engaged with the inner peripheral surface of the powder input portion of the hopper.

撹拌部材１３を取り付けた状態で、ホッパー１１に対し振動機構から微振動が伝達されると、撹拌部材１３は、ホッパー１１に対して固定されていないので、微振動によってホッパー１１の内部で移動する。このとき、撹拌部材１３の挿入部１３ａはホッパー１１の吐出部１１ｂに挿入されているので、ホッパー１１に対する撹拌部材１３の位置が大きく変化することがない。その結果、撹拌部材１３は、撹拌部１３ｂを上下に振動させながら、挿入部１３ａを軸として回転するように移動する。 When microvibration is transmitted from the vibrating mechanism to the hopper 11 with the stirring member 13 attached, the stirring member 13 moves inside the hopper 11 due to the microvibration because it is not fixed to the hopper 11. . At this time, since the insertion portion 13a of the stirring member 13 is inserted into the discharge portion 11b of the hopper 11, the position of the stirring member 13 with respect to the hopper 11 does not change significantly. As a result, the stirring member 13 moves so as to rotate about the insertion portion 13a while vertically vibrating the stirring portion 13b.

また、この粉体供給装置では、撹拌部材１３の挿入部と撹拌部１３ｂとがなす角度θ１が、ホッパー１１の吐出部１１ｂの内周面と粉体投入部１１ａの内周面とがなす角度θ２とは異なるように構成されているため、ホッパー１１の粉体投入部１１ａの内周面と撹拌部材１３の撹拌部１３ｂの下方側の面との間には、常に所定の間隔が形成される。これにより、撹拌部材１３が移動している際には、その間隔に粉体が順次引き込まれる。また、仮に粉体が固化していた場合には、粉体投入部１１ａの内周面と撹拌部１３ｂの下方側の面との間で、その固化した粉体が粉砕される。 Further, in this powder feeder, the angle θ1 formed by the insertion portion of the stirring member 13 and the stirring portion 13b is the angle formed by the inner peripheral surface of the discharge portion 11b of the hopper 11 and the inner peripheral surface of the powder charging portion 11a. Since it is configured to be different from θ2, a predetermined gap is always formed between the inner peripheral surface of the powder charging portion 11a of the hopper 11 and the surface on the lower side of the stirring portion 13b of the stirring member 13. be. As a result, when the stirring member 13 is moving, the powder is sequentially drawn into the gap. Further, if the powder is solidified, the solidified powder is pulverized between the inner peripheral surface of the powder input portion 11a and the lower surface of the stirring portion 13b.

以上説明したように、粉体供給装置１では、簡易な構成でありながら、撹拌部材１３が安定した挙動を行い、また、撹拌部材１３による粉体Ｐの引き込み、粉砕及び吐出が行われるので、十分に、安定した粉体Ｐの撹拌、ひいては、粉体Ｐの供給が実現できる。 As described above, in the powder feeder 1, although the structure is simple, the stirring member 13 behaves stably, and the powder P is drawn in, pulverized, and discharged by the stirring member 13. Sufficiently stable agitation of the powder P and eventually supply of the powder P can be realized.

なお、上記実施形態においては、ホッパー１１の粉体投入部１１ａの内周面と撹拌部材１３の撹拌部１３ｂの下方側の面との間に所定の間隔を形成するために、撹拌部材１３の挿入部１３ａと撹拌部１３ｂとがなす角度θ１を、ホッパー１１の吐出部１１ｂの内周面と粉体投入部１１ａの内周面とがなす角度θ２よりも小さく形成している。
しかし、本発明はそのような構成に限定されるものではない。例えば、角度θ１を角度θ２よりも大きく構成してもよい。
図２は、本発明の実施の形態に係る粉体供給装置の変形例の要部の構造を断面で示す斜視図である。 In the above-described embodiment, in order to form a predetermined gap between the inner peripheral surface of the powder charging portion 11a of the hopper 11 and the lower surface of the stirring portion 13b of the stirring member 13, the stirring member 13 is The angle θ1 formed between the insertion portion 13a and the stirring portion 13b is formed smaller than the angle θ2 formed between the inner peripheral surface of the discharge portion 11b of the hopper 11 and the inner peripheral surface of the powder charging portion 11a.
However, the invention is not limited to such configurations. For example, the angle θ1 may be made larger than the angle θ2.
FIG. 2 is a perspective view showing a cross-section of the structure of a main part of a modification of the powder feeder according to the embodiment of the present invention.

この変形例では、撹拌部材１３の撹拌部１３ｂに、撹拌部１３ｂからホッパー１１の粉体投入部１１ａの内周面側に向かって突出する突起１３ｄ（間隔維持部）が設けられている。突起１３ｄを設けることで、ホッパー１１の粉体投入部１１ａの内周面と撹拌部材１３の撹拌部１３ｂの下方側の面との間に所定の間隔を形成している。なお、変形例の場合には、挿入部１３ａと撹拌部１３ｂとがなす角度θ１と、ホッパー１１の吐出部１１ｂの内周面と粉体投入部１１ａの内周面とがなす角度θ２は、同じでもよく、異なっていてもよい。 In this modified example, the stirring portion 13b of the stirring member 13 is provided with a protrusion 13d (interval maintaining portion) that protrudes from the stirring portion 13b toward the inner peripheral surface of the powder input portion 11a of the hopper 11 . By providing the projection 13d, a predetermined gap is formed between the inner peripheral surface of the powder input portion 11a of the hopper 11 and the surface of the stirring member 13 on the lower side of the stirring portion 13b. In the case of the modified example, the angle θ1 formed between the insertion portion 13a and the stirring portion 13b and the angle θ2 formed between the inner peripheral surface of the discharge portion 11b of the hopper 11 and the inner peripheral surface of the powder input portion 11a are They may be the same or different.
