Description

本発明は、粒体から粉体を分離するための粉取り集塵装置及びそれを用いた粉体分離システムに関する。   The present invention relates to a dust collecting apparatus for separating powder from granules and a powder separation system using the same.

射出成形機などでは成形品の材料は粒体状のペレットとして供給されるが、ペレットに材料が粉体の状態で付着していると不良品の原因となる。   In an injection molding machine or the like, the material of a molded product is supplied as a granular pellet. However, if the material adheres to the pellet in the form of powder, a defective product is caused.

ペレットが欠けることによって発生した粉体材料は、材料を加熱溶融する成形機のスクリュー及び加熱筒内でペレットよりも早く溶融してスクリュー表面に滞留するため、ペレットよりも長時間加熱され、スクリューの表面や加熱筒内面に焼き付いてしまう。焼き付いた粉体が剥がれて成形材料の中に混入すると、成形品に含まれる焼けた粉体材料は黒点として現れて成形不良を発生させる。   The powder material generated by chipping of the pellet melts faster than the pellet in the screw and heating cylinder of the molding machine that heats and melts the material and stays on the screw surface. It will burn into the surface and the inner surface of the heating cylinder. When the burned-in powder is peeled off and mixed in the molding material, the burnt powder material contained in the molded product appears as a black spot and causes molding defects.

また、粉体材料が塊となってペレットと一緒に成形機へ供給されると、加熱溶融された成形材料の温度や密度が不均一となり、成形品の寸法や重量が規格から外れることがある。   Also, if the powder material is agglomerated and supplied to the molding machine together with the pellets, the temperature and density of the heated and melted molding material may become uneven, and the size and weight of the molded product may deviate from the standard. .

また、粒体材料に粉体状の埃や不純物などが混入すると、成形品の美観を損ねたり、成形不良の原因となることもあった。   In addition, when powdery dust or impurities are mixed in the granular material, the appearance of the molded product may be impaired, or molding may be caused.

このため、従来では、成形機に供給する前段階で粒体から粉体を分離し、分離した粉体をフィルタで集める手法が用いられていた。   For this reason, conventionally, a method has been used in which the powder is separated from the granule before being supplied to the molding machine, and the separated powder is collected by a filter.

このような従来技術としては特許文献１に開示される「粉体材料の分離・回収システム」がある。
特開２００５−２１１７３７号公報 As such a prior art, there is a “powder material separation / recovery system” disclosed in Patent Document 1.
JP-A-2005- 211737

しかし、特許文献１に開示される発明のような分離する室内にフィルタが存在する従来構成では、
・フィルタが存在することにより粉取り性能が悪い。
・フィルタに衝突してペレットが欠け、粉体を発生させる。

本発明の好適な実施形態について説明する。図１に、本実施形態にかかる集塵システムの構成を示す。この集塵システムは、ブロワ１と原料容器２とローダ／粉取り集塵部３とを有する。   A preferred embodiment of the present invention will be described. In FIG. 1, the structure of the dust collection system concerning this embodiment is shown. This dust collection system includes a blower 1, a raw material container 2, and a loader / powder collection dust collection unit 3.

ブロワ１から送出される空気は、原料容器２へ送り込まれ、原料である粒体とともに原料容器２内で乾燥させられる。原料容器２内で乾燥させられた空気は、容器の上部に設けられた空気口又は容器の下部に設けられた原料口のいずれかから出てローダ粉取り集塵部３へと向かう。空気が原料口から出てローダ粉取り集塵部３へ向かう場合は、乾燥済みの粒体を巻き込んで移送する。空気が空気口から出てローダ粉取り集塵部３へ向かう場合は、乾燥済みの粒体は移送されない。   The air sent out from the blower 1 is sent into the raw material container 2 and dried in the raw material container 2 together with the granule as the raw material. The air dried in the raw material container 2 exits from either the air port provided in the upper part of the container or the raw material port provided in the lower part of the container and heads toward the loader powder collecting unit 3. When air exits from the raw material port and travels toward the loader powder collecting unit 3, the dried granule is taken up and transferred. When air exits from the air port and travels toward the loader powder collecting unit 3, the dried granules are not transferred.

図２に、原料移送時のローダ粉取り集塵部を示す。図３に、粉体分離時のローダ粉取り集塵部を示す。
ローダ粉取り集塵部３は、第１の吸引管１１、第２の吸引管１２、第１切替弁１３、粒体引き込み部１４、圧送管１５、粉取室１６、シャッタ１７、粒体受け容器１８、粉体排出管１９、排気管２０、第２切替弁２１、集塵容器２２、フィルタ２３を有する。
第１の吸引管１１は原料容器２の空気口と接続されている。第２の吸引管１２は原料容器２の原料口と接続されている。第１切替弁１３は第１の吸引管１１及び第２の吸引管１２の何れかを塞ぎ、他方の吸引管を介して原料容器２と粒体引き込み部１４とを連通させる。粒体引き込み部１４は、下部が下に凸の漏斗形状となっており、管の部分は圧送管１５として粉取室１６内まで達している。また、粒体引き込み部１４には空気の流入口よりも上方にフィルタ２４が設けられており、フィルタ２４よりもさらに上方に設けられた開口は排気管２０と接続されている。フィルタ２４は、粒体を分離するための目の粗いフィルタである。 FIG. 2 shows a loader powder collecting unit for transferring raw materials. FIG. 3 shows a loader dust collecting part during powder separation.
The loader powder collecting dust collecting unit 3 includes a first suction pipe 11, a second suction pipe 12, a first switching valve 13, a granule drawing-in part 14, a pressure feeding pipe 15, a dust collecting chamber 16, a shutter 17, and a granule receiver. It has a container 18, a powder discharge pipe 19, an exhaust pipe 20, a second switching valve 21, a dust collection container 22, and a filter 23.
The first suction pipe 11 is connected to the air port of the raw material container 2. The second suction pipe 12 is connected to the raw material port of the raw material container 2. The first switching valve 13 closes either the first suction pipe 11 or the second suction pipe 12 and allows the raw material container 2 and the granule drawing-in part 14 to communicate with each other through the other suction pipe. The granule drawing-in portion 14 has a funnel shape with a convex portion at the bottom, and the portion of the tube reaches the inside of the powder collecting chamber 16 as a pressure feeding tube 15. Further, a filter 24 is provided above the air inlet 14 in the granular material inlet 14, and an opening provided further above the filter 24 is connected to the exhaust pipe 20. The filter 24 is a coarse filter for separating particles.

粉取室１６は、底面が下に凸の錐形状であり、錐の部分は粉体受け容器１８に挿入されており、その先端には開口が設けられている。開口はシャッタ１７によって開閉自在である。粉取室１６の上部は、粉体排出管１９に接続されている。
集塵容器２２は排気管２０を介して粒体引き込み部１４に、粉体排出管１９を介して粉取室１６にそれぞれ接続されている。第２切替弁２１は、集塵容器２２を粒体引き込み部１４又は粉取室１６のいずれか一方と連通させる。
集塵容器２２には空気の入口と出口との間にフィルタ２３が設けられている。フィルタ２３は、粉体を分離するための目の細かいフィルタである。集塵容器２２から出た空気は再度ブロワ１に入り、上記の系（ブロワ１、原料容器２、及びローダ／粉取り集塵部３）の内部で循環する。 The dust collecting chamber 16 has a conical shape with a bottom projecting downward, and the conical portion is inserted into the powder receiving container 18, and an opening is provided at the tip thereof. The opening can be freely opened and closed by a shutter 17. The upper part of the powder chamber 16 is connected to a powder discharge pipe 19.
The dust collecting container 22 is connected to the granule drawing part 14 via the exhaust pipe 20 and to the powder collecting chamber 16 via the powder discharge pipe 19. The second switching valve 21 causes the dust collection container 22 to communicate with either the granule drawing part 14 or the powder collection chamber 16.
The dust collecting container 22 is provided with a filter 23 between an air inlet and an outlet. The filter 23 is a fine filter for separating powder. The air discharged from the dust collecting container 22 enters the blower 1 again and circulates inside the above system (blower 1, raw material container 2, and loader / powder collecting dust collecting unit 3).

第１切替弁１３と第２切替弁２１とは連動して切り替わるように制御され、第１切替弁１３が第２の吸引管１２を塞ぐ場合には、第２切替弁２１は排気管２０を塞ぐ。逆に、第１切替弁１３が第１の吸引管１１を塞ぐ場合には、第２切替弁は粉体排出管１９を塞ぐ。   The first switching valve 13 and the second switching valve 21 are controlled to be switched in conjunction with each other. When the first switching valve 13 closes the second suction pipe 12, the second switching valve 21 opens the exhaust pipe 20. Block it. Conversely, when the first switching valve 13 closes the first suction pipe 11, the second switching valve closes the powder discharge pipe 19.

本実施形態にかかる集塵システムの動作について説明する。
まず、第１切替弁１３及び第２切替弁２１を制御して、第１切替弁１３が第１の吸引管１１を塞ぎ、第２切替弁２１が粉体排出管１９を塞いだ状態（図２に示した）とする。この時には、ブロワ１→原料容器２→第２吸引管１２→粒体引き込み部１４→排気管２０→集塵容器２２→ブロワ１という流路が形成された状態となっている。
この状態でブロワ１から原料容器２に空気を送り込むと、原料容器２内の乾燥済み原料は空気とともに第２の吸引管１２へ流れ込む。粒体を含んだ空気が粒体引き込み部１４に到達すると、粒体引き込み部１４内のフィルタ２４によって粒体が分離される。粒体が分離された空気は、排気管２０を介して集塵容器２２に流れ込み、フィルタ２３によって粉体等が除去され、清浄な空気のみがブロワ１へと戻る。
粒体引き込み部１４のフィルタ２４において分離された粒体は、自重により落下し、圧送管１５を介して粉取室１６へと移動する。 The operation of the dust collection system according to this embodiment will be described.
First, the first switching valve 13 and the second switching valve 21 are controlled so that the first switching valve 13 closes the first suction pipe 11 and the second switching valve 21 closes the powder discharge pipe 19 (FIG. 2). At this time, a flow path of blower 1 → raw material container 2 → second suction pipe 12 → granule drawing part 14 → exhaust pipe 20 → dust collecting container 22 → blower 1 is formed.
When air is sent from the blower 1 to the raw material container 2 in this state, the dried raw material in the raw material container 2 flows into the second suction pipe 12 together with the air. When the air containing the particles reaches the particle pull-in portion 14, the particles are separated by the filter 24 in the particle pull-in portion 14. The air from which the particles have been separated flows into the dust collecting container 22 through the exhaust pipe 20, and powder and the like are removed by the filter 23, and only clean air returns to the blower 1.
The granule separated in the filter 24 of the granule drawing-in part 14 falls due to its own weight, and moves to the powder collecting chamber 16 via the pressure feeding tube 15.

所定時間ブロワ１により空気を原料容器２内へ送り込んだら、第１切替弁１３及び第２切替弁２１を制御して、第１切替弁１３が第２の吸引管１２を塞ぎ、第２切替弁２１が排気管２０を塞いだ状態（図３に示した状態）とする。この時には、ブロワ１→原料容器２→第１吸引管１１→粒体引き込み部１４→圧送管１５→粉取室１６→粉体排出管１９→集塵容器２２→ブロワ１という流路が形成された状態となっている。この状態では、原料容器２からは空気のみが流れ出るため、粉取室１６には粒体が供給されない。よって、粉取室１６には、第１切替弁１３が第１の吸引管１１を塞いでいた時間に応じた所定量の粒体が収容されている。
この状態では、原料容器２を通過した空気が第１の吸引管１１を介して粒体引き込み部１４へ流れ込み、圧送管１５を介して粉取室１６へ流入する。粉取室１６の底面が下に凸の錐形状となっているため、粉取室１６へ流入した空気は既に蓄積されている粒体を巻き上げ、撹拌させる。この撹拌によって粒体と粉体とが分離され、落下抵抗の小さい粒体は粉取室１６内に留まったまま撹拌され続ける。一方、落下抵抗の大きい粉体は、粉取室１６内に沈降せずに空気とともに粉体排出管１９へと流れ込み、集塵容器２２へ移送される。集塵容器２２においてはフィルタ２３によって粉体が濃し取られ、清浄な空気のみがブロワ１へと戻る。 When air is fed into the raw material container 2 by the blower 1 for a predetermined time, the first switching valve 13 and the second switching valve 21 are controlled so that the first switching valve 13 closes the second suction pipe 12 and the second switching valve 21 is a state where the exhaust pipe 20 is blocked (the state shown in FIG. 3). At this time, the flow path of the blower 1 → the raw material container 2 → the first suction pipe 11 → the granule drawing portion 14 → the pressure feeding pipe 15 → the powder collecting chamber 16 → the powder discharge pipe 19 → the dust collecting container 22 → the blower 1 is formed. It is in a state. In this state, since only air flows out from the raw material container 2, no granule is supplied to the milling chamber 16. Therefore, a predetermined amount of particles corresponding to the time during which the first switching valve 13 has closed the first suction pipe 11 is accommodated in the powder removal chamber 16.
In this state, the air that has passed through the raw material container 2 flows into the granule drawing part 14 through the first suction pipe 11 and flows into the powder collecting chamber 16 through the pressure feeding pipe 15. Since the bottom surface of the milling chamber 16 has a convex conical shape, the air that has flowed into the milling chamber 16 rolls up the already accumulated particles and stirs them. By this stirring, the granules and the powder are separated, and the granules having a low drop resistance are kept stirring in the powder collecting chamber 16. On the other hand, the powder having a high drop resistance flows into the powder discharge pipe 19 together with the air without being settled in the powder collecting chamber 16 and is transferred to the dust collecting container 22. In the dust collection container 22, the powder is concentrated by the filter 23, and only clean air returns to the blower 1.

粉取室１６内で所定時間粒体を撹拌した後に、粉取室１６下部の開口を塞ぐシャッタ１７を開放することにより、粉体が除去された粒体が粒体受け容器１８に投入される。   After stirring the granules in the powdering chamber 16 for a predetermined time, the shutter 17 that closes the opening at the bottom of the powdering chamber 16 is opened, whereby the particles from which the powder has been removed are put into the particle receiving container 18. .

１回で処理できる量よりも多くの粒体から粉体を分離・除去する場合には、上記の処理を繰り返し行えばよい。   When the powder is separated and removed from more particles than can be processed at one time, the above process may be repeated.

本実施形態に係る集塵システムでは、ブロワ１を駆動する時間及び発生させる風圧を調整することにより、粒体と粉体との分離の程度を任意に調整可能であるため、仕様の変更などに柔軟に対応することが可能である。
また、粉取室１６はフィルタレスの構造となっているため粉取性能に優れ、フィルタに付着した粉体がダマとなって脱落し、粒体に混入することがない。
また、粉体と粒体との落下抵抗の差を利用してこれらを分別するため、粉体や粒体の材質に依らず適用可能であり、粉砕材であっても本実施形態にかかる集塵システムで粉体を分離・除去可能である。
さらに、ブロワ１から送出した空気を再度ブロワ１に入力するクローズドループの構成とすることで、粉体を含んだ空気が外気に触れることが無くなるため、乾燥済みの粒体が再吸湿したり、原料に埃などが混入したり、装置の周囲の雰囲気を粉体で汚染したりすることがない。 In the dust collection system according to the present embodiment, the degree of separation between the granular material and the powder can be arbitrarily adjusted by adjusting the time for driving the blower 1 and the generated wind pressure. It is possible to respond flexibly.
Further, since the dust removing chamber 16 has a filterless structure, the powder removing performance is excellent, and the powder adhering to the filter does not fall off and is not mixed into the granules.
Further, since these are separated using the difference in drop resistance between the powder and the granule, it can be applied regardless of the material of the powder or granule. Powders can be separated and removed with a dust system.
Furthermore, since the air sent out from the blower 1 is configured as a closed loop in which the air is again input to the blower 1, the air containing the powder does not come into contact with the outside air. There is no possibility that dust or the like is mixed in the raw material or the atmosphere around the apparatus is contaminated with powder.

なお、上記実施形態は本発明の好適な実施の一例であり、本発明はこれに限定されることはない。
例えば、上記実施形態では、第１切替弁と第２切替弁とが連動して制御される構成を例としたが、第１切替弁と第２切替弁とを個別に制御して、上記同様に流露を形成するようにしても良い。
また、第１切替弁及び第２切替弁として三方弁を用いた構成を図示したが、必ずしも三方弁を用いた構成とする必要はなく、第１の吸引管１１と第２の吸引管１２、粉体排出管１９と排気管２０はそれぞれ独立した配管であってもよい。
このように、本発明は様々な変形が可能である。 In addition, the said embodiment is an example of suitable implementation of this invention, and this invention is not limited to this.
For example, in the above embodiment, the configuration in which the first switching valve and the second switching valve are controlled in conjunction with each other is taken as an example. However, the first switching valve and the second switching valve are individually controlled, and the same as above. A dew may be formed on the surface.
In addition, although a configuration using a three-way valve as the first switching valve and the second switching valve is illustrated, it is not always necessary to use a three-way valve, and the first suction pipe 11 and the second suction pipe 12, The powder discharge pipe 19 and the exhaust pipe 20 may be independent pipes.
As described above, the present invention can be variously modified.
