以下、本発明に係る材料混合装置を実施するための形態を図面に基づいて説明する。 Hereinafter, the form for implementing the material mixing apparatus which concerns on this invention is demonstrated based on drawing.
この形態では、ペットボトルをリサイクルするためにフレーク状に粉砕され洗浄処理された原材料Ｆを混合して縮重合処理等を行う混合材料Ｍを製造するものを示してある。 In this embodiment, a mixed material M for mixing a raw material F that has been crushed into flakes and washed for recycling PET bottles and performing a condensation polymerization process or the like is shown.
原材料Ｆは、大きさ，ペットボトルのメーカ等により複数種類が用意され、例えばシート状，綿状からなるリサイクル製品の粘度調整のために混合比が調整される。 A plurality of types of raw materials F are prepared depending on the size, the manufacturer of the PET bottle, and the like, and the mixing ratio is adjusted for adjusting the viscosity of a recycled product made of, for example, a sheet or cotton.
この形態は、図１に示すように、原材料ホッパ１，混合材料ホッパ２，排出機構３，供給機構４，コントローラ５を主要部として構成されている。 In this embodiment, as shown in FIG. 1, the raw material hopper 1, the mixed material hopper 2, the discharge mechanism 3, the supply mechanism 4, and the controller 5 are mainly configured.

The mixed material hopper 2 is provided with a sensor 6 that detects whether or not the amount of the mixed material M stored is below a certain amount. The mixed material hopper 2 is connected to a conveying means (not shown) for conveying the mixed material M to an apparatus for performing a condensation polymerization process or the like.
排出機構３は、原材料ホッパ１の底部１２の下端にほぼ水平方向に配設され原材料ホッパ１から原材料Ｆを排出するもので、円筒形の外パイプ３１と、外パイプ３１の内部に回転可能に支持されたスクリュコンベア３２と、スクリュコンベア３２を回転駆動する排出モータ３３とからなる。この排出機構３は、各原材料ホッパ１に備えられ個別に駆動が可能になっている。 The discharge mechanism 3 is disposed substantially horizontally at the lower end of the bottom portion 12 of the raw material hopper 1 and discharges the raw material F from the raw material hopper 1. The discharge mechanism 3 is rotatable inside the cylindrical outer pipe 31 and the outer pipe 31. It comprises a supported screw conveyor 32 and a discharge motor 33 that rotationally drives the screw conveyor 32. The discharge mechanism 3 is provided in each raw material hopper 1 and can be driven individually.
供給機構４は、各排出機構３の原材料Ｆの排出側端部の下方に直交するほぼ水平方向に配設されて各排出機構３に直列が連結され排出された原材料Ｆを混合しながら混合材料ホッパ２に供給するもので、円筒形の外パイプ４１と、外パイプ４１の内部に回転可能に支持されたスクリュコンベア４２と、スクリュコンベア４２を回転駆動する排出モータ４３とからなる。スクリュコンベア４２は、図２に示すように、単一の供給モータ４３によって回転駆動される単一の回転軸４２ａを有し、フィン４２ｂが回転軸４２ａの軸長の中途で逆方向へ旋回されている。スクリュコンベア４２のフィン４２ｂの方向変換部分では、一定ピッチ分のフィン４２ｂが省略されている。スクリュコンベア４２のフィン４２ｂの方向変換部分の周囲では、方形の合流箱７が外パイプ４１に連結され、下部に混合材料ホッパ２に連結した供給筒８が連結され、上部に整流板９が設けられている。整流板９は、図３に示すように、スクリュコンベア４２の軸方向と直交する方向に合流箱７の内部に掛渡された支持アーム９１と、支持アーム９１に直交するように支持されスクリュコンベア４２の回転軸４２ａ近くまで延びた方形板の整流板本体９２とからなる。 The supply mechanism 4 is disposed in a substantially horizontal direction orthogonal to the lower side of the discharge side end portion of the raw material F of each discharge mechanism 3 and is connected in series to each discharge mechanism 3 to mix the discharged raw material F while mixing the discharged raw materials F It is supplied to the hopper 2 and includes a cylindrical outer pipe 41, a screw conveyor 42 rotatably supported inside the outer pipe 41, and a discharge motor 43 that rotationally drives the screw conveyor 42. As shown in FIG. 2, the screw conveyor 42 has a single rotating shaft 42a that is rotationally driven by a single supply motor 43, and the fins 42b are swung in the reverse direction in the middle of the axial length of the rotating shaft 42a. ing. In the direction changing portion of the fins 42b of the screw conveyor 42, the fins 42b for a certain pitch are omitted. Around the direction changing portion of the fin 42b of the screw conveyor 42, the rectangular junction box 7 is connected to the outer pipe 41, the supply cylinder 8 connected to the mixed material hopper 2 is connected to the lower part, and the current plate 9 is provided to the upper part. It has been. As shown in FIG. 3, the rectifying plate 9 is supported by the support arm 91 spanned in the junction box 7 in a direction orthogonal to the axial direction of the screw conveyor 42 and the screw conveyor supported so as to be orthogonal to the support arm 91. 42, and a rectangular plate rectifying plate main body 92 extending to the vicinity of the rotating shaft 42a.
コントローラ５は、排出機構３，供給機構４の駆動を制御するもので、図４に示すような操作部５１，コントロール部５２，電気回路部５３からなる。操作部５１は、メインスイッチである駆動スイッチ５１ａと、各排出機構３の排出モータ３３の回転数（単位時間当たりの）を個別に設定する回転数設定部５１ｂとを備えている。コントロール部５２は、マイクロプロセッサを内蔵して操作部５１の操作等によって電気回路部５３を制御するものである。なお、前述のセンサ６がコントロール部５２に接続され、コントロール部５２にはセンサ６が混合材料ホッパ２における混合材料Ｍの貯留量が一定量以上である信号を発信した場合に排出機構３，供給機構４を駆動させず一定量以下である信号を発信した場合に排出機構３，供給機構４を駆動させるようにプログラムが入力されている。電気回路部５３は、排出機構３の排出モータ３３と供給機構４の供給モータ４３とに接続されている。 The controller 5 controls the driving of the discharge mechanism 3 and the supply mechanism 4, and includes an operation unit 51, a control unit 52, and an electric circuit unit 53 as shown in FIG. The operation unit 51 includes a drive switch 51a that is a main switch, and a rotation speed setting unit 51b that individually sets the rotation speed (per unit time) of the discharge motor 33 of each discharge mechanism 3. The control unit 52 incorporates a microprocessor and controls the electric circuit unit 53 by operating the operation unit 51 or the like. The above-described sensor 6 is connected to the control unit 52. When the sensor 6 transmits a signal indicating that the amount of the mixed material M stored in the mixed material hopper 2 is equal to or larger than a predetermined amount, the control unit 52 supplies the discharge mechanism 3. A program is input so as to drive the discharge mechanism 3 and the supply mechanism 4 when the mechanism 4 is not driven and a signal of a certain amount or less is transmitted. The electric circuit unit 53 is connected to the discharge motor 33 of the discharge mechanism 3 and the supply motor 43 of the supply mechanism 4.
この形態によると、供給機構４のスクリュコンベア４２のフィン４２ｂの方向変換部分で供給機構４，混合材料ホッパ２が供給筒８で連結されているため、混合材料ホッパ２を供給機構４の長さ方向（軸長）の端部に設置しなくてもすむようになるため、全体の構造が小型化される。 According to this embodiment, since the supply mechanism 4 and the mixed material hopper 2 are connected by the supply cylinder 8 at the direction changing portion of the fin 42 b of the screw conveyor 42 of the supply mechanism 4, the mixed material hopper 2 is connected to the length of the supply mechanism 4. Since it does not need to be installed at the end of the direction (axial length), the entire structure is reduced in size.
この形態で混合材料Ｍを量産するには、図５に示す操作，制御が実行される。 In order to mass-produce the mixed material M in this form, the operation and control shown in FIG. 5 are executed.
まず、コントローラ５の操作部５１の回転数設定部５１ｂを操作して、各排出機構３の排出モータ３３の回転数をそれぞれ設定する。この設定は、原材料ホッパ１からの原材料Ｆの排出量（単位時間当たりの）を設定することになる。即ち、回転数設定部５１ｂの簡単な操作で原材料Ｆの混合比を調整できることになる。 First, the rotation speed setting unit 51 b of the operation unit 51 of the controller 5 is operated to set the rotation speed of the discharge motor 33 of each discharge mechanism 3. In this setting, the discharge amount (per unit time) of the raw material F from the raw material hopper 1 is set. That is, the mixing ratio of the raw materials F can be adjusted by a simple operation of the rotation speed setting unit 51b.
次ぎに、コントローラ５の操作部５１の駆動スイッチ５１ａをＯＮにする。 Next, the drive switch 51a of the operation unit 51 of the controller 5 is turned ON.
駆動スイッチ５１ａがＯＮになった状態で、センサ６が混合材料ホッパ２における混合材料Ｍの貯留量が一定量以上である信号を発信した場合、コントロール部５２のコントロール部５２が電気回路部５３に対して排出機構３の排出モータ３３と供給機構４の供給モータ４３との駆動の指示を行わない。従って、排出機構３，供給機構４の無用の駆動を避けることができるため、混合材料Ｍの製造のための運転コストが低減される。 When the sensor 6 transmits a signal indicating that the amount of the mixed material M stored in the mixed material hopper 2 is equal to or larger than a certain amount in the state where the drive switch 51 a is turned on, the control unit 52 of the control unit 52 sends the signal to the electric circuit unit 53. On the other hand, the drive instruction of the discharge motor 33 of the discharge mechanism 3 and the supply motor 43 of the supply mechanism 4 is not performed. Therefore, unnecessary driving of the discharge mechanism 3 and the supply mechanism 4 can be avoided, and the operating cost for manufacturing the mixed material M is reduced.
駆動スイッチ５１ａがＯＮになった状態で、センサ６が混合材料ホッパ２における混合材料Ｍの貯留量が一定量以下である信号を発信した場合、コントロール部５２のコントロール部５２が電気回路部５３に対して排出機構３の排出モータ３３と供給機構４の供給モータ４３との駆動の指示を行う。 When the sensor 6 transmits a signal indicating that the amount of the mixed material M stored in the mixed material hopper 2 is equal to or less than a certain amount in the state where the drive switch 51 a is turned on, the control unit 52 of the control unit 52 sends the signal to the electric circuit unit 53. On the other hand, an instruction to drive the discharge motor 33 of the discharge mechanism 3 and the supply motor 43 of the supply mechanism 4 is given.
排出機構３の排出モータ３３と供給機構４の供給モータ４３とが駆動されると、各排出機構３の排出モータ３３がそれぞれ設定された回転数で回転駆動され、各原材料ホッパ１から原材料Ｆの必要な排出量が得られることになる。 When the discharge motor 33 of the discharge mechanism 3 and the supply motor 43 of the supply mechanism 4 are driven, the discharge motor 33 of each discharge mechanism 3 is driven to rotate at a set number of rotations, and the raw material F is fed from each raw material hopper 1. Necessary emissions will be obtained.
排出機構３の排出モータ３３で原材料ホッパ１から排出された原材料Ｆは、供給機構４で混合されながら相対する方向から合流箱７へ向けて送られる。 The raw material F discharged from the raw material hopper 1 by the discharge motor 33 of the discharge mechanism 3 is sent toward the junction box 7 from the opposite direction while being mixed by the supply mechanism 4.
合流箱７では、旋回されながら送られてきた原材料Ｆ（混合材料Ｍ）が整流板９の整流板本体９２に規制されて混合材料ホッパ２（供給筒８）に向けて案内される。従って、相対する方向から送られてきた原材料Ｆ（混合材料Ｍ）が衝突することないため、原材料Ｆ（混合材料Ｍ）の滞溜が防止されて混合材料ホッパ２への円滑な流れが形成される。この結果、混合材料Ｍを確実に量産することができることになる。なお、図３は、合流箱７の上面を閉塞している蓋を外した状態を示している。 In the junction box 7, the raw material F (mixed material M) sent while being swung is regulated by the rectifying plate body 92 of the rectifying plate 9 and guided toward the mixed material hopper 2 (supply cylinder 8). Therefore, since the raw material F (mixed material M) sent from the opposite direction does not collide, the stagnation of the raw material F (mixed material M) is prevented and a smooth flow to the mixed material hopper 2 is formed. The As a result, the mixed material M can be reliably mass-produced. FIG. 3 shows a state in which the lid that closes the upper surface of the junction box 7 is removed.
混合材料ホッパ２への混合材料Ｍの供給によって、センサ６が混合材料ホッパ２における混合材料Ｍの貯留量が一定量以上である信号を発信した場合、コントロール部５２のコントロール部５２が電気回路部５３に対して排出機構３の排出モータ３３と供給機構４の供給モータ４３との駆動の停止を指示する。 When the mixed material M is supplied to the mixed material hopper 2 and the sensor 6 transmits a signal indicating that the amount of the mixed material M stored in the mixed material hopper 2 is equal to or larger than a certain amount, the control unit 52 of the control unit 52 controls the electric circuit unit. 53 is instructed to stop driving the discharge motor 33 of the discharge mechanism 3 and the supply motor 43 of the supply mechanism 4.
この後、必要ならば、混合材料ホッパ２へ供給された混合材料Ｍにおける原材料Ｆの混合比をサンプル調査する。そして、必要ならば、コントローラ５の操作部５１の回転数設定部５１ｂを操作して、各排出機構３の排出モータ３３の回転数をそれぞれ再設定する。 Thereafter, if necessary, the mixing ratio of the raw material F in the mixed material M supplied to the mixed material hopper 2 is sampled. Then, if necessary, the rotation speed setting unit 51b of the operation unit 51 of the controller 5 is operated to reset the rotation speed of the discharge motor 33 of each discharge mechanism 3 respectively.
さらに、この形態では、原材料ホッパ１に貯留されている原材料Ｆが密閉構造の排出機構３，供給機構４を介して混合材料ホッパ２へ供給されるため、外気との接触による汚損が防止される。従って、ペットボトルを食品容器としてリサイクルするリサイクル処理システムへの設置に好適となる。 Furthermore, in this embodiment, since the raw material F stored in the raw material hopper 1 is supplied to the mixed material hopper 2 via the discharge mechanism 3 and the supply mechanism 4 having a sealed structure, contamination due to contact with outside air is prevented. . Therefore, it is suitable for installation in a recycling processing system that recycles PET bottles as food containers.
以上、図示した形態の外に、原材料ホッパ１を２基または４基以上設置することも可能である。 As described above, two or four or more raw material hoppers 1 can be installed in addition to the illustrated form.
本発明に係る材料混合装置は、ペットボトルをリサイクル以外の合成樹脂，食品等の分野において、粉粒状の原材料の取扱いに広範に利用することが可能である。 The material mixing apparatus according to the present invention can be widely used for handling powdery raw materials in fields such as synthetic resins other than recycling plastics and foods.
