Description

本発明は、粉粒体を原料として貯蔵するホッパの如き貯蔵容器内の原料を各種処理装置へ搬送させるようにするために貯蔵容器内から切り出すようにする貯蔵容器内原料の切出し方法及び装置に関するものである。   The present invention relates to a method and an apparatus for cutting out a raw material in a storage container so as to cut out the raw material in a storage container such as a hopper for storing powder particles as a raw material from various storage devices. Is.

従来、貯蔵容器内の粉粒体の如き原料を切り出して目的のところまで搬送させるようにするものとして、図２に示す如き粉粒体の切出し装置がある。   2. Description of the Related Art Conventionally, there is a powder particle cutting device as shown in FIG. 2 to cut out raw materials such as powder particles in a storage container and transport them to a target.

すなわち、粉粒体を貯蔵する貯蔵ホッパ１の下部に、スクリューフィーダ２を設け、該スクリューフィーダ２の両端に設けられた排出口４ａ，４ｂに、それぞれ搬送配管５ａと５ｂを接続し、該各搬送配管５ａ，５ｂに吹き込み配管６ａ，６ｂをそれぞれ連通して設けると共に、該吹き込み配管６ａ，６ｂと上記搬送配管５ａ，５ｂに開閉弁Ｖ１とＶ１、Ｖ２とＶ２を設けた構成としてある。更に、上記搬送配管５ａ，５ｂには閉塞検知装置７ａ，７ｂを設け、該閉塞検出器７ａ，７ｂは、搬送配管５ａ，５ｂの閉塞を検知して、検知信号を制御装置８に入力し、制御装置８は、閉塞検知装置７ａ，７ｂの検知信号を入力して、駆動用モータ３の回転及び開閉弁Ｖ１とＶ１及びＶ２とＶ２の開閉を制御するようにしてある。 That is, the screw feeder 2 is provided at the lower part of the storage hopper 1 for storing powder particles, and the conveying pipes 5a and 5b are connected to the discharge ports 4a and 4b provided at both ends of the screw feeder 2, respectively. conveying pipe 5a, the pipe 6a blown into 5b, 6b with the provision communicated respectively, the blowing pipe 6a, 6b and the conveying pipe 5a, the opening and closing valve V 1 and V 1, V 2 and V 2 to 5b provided configuration It is as. Further, the conveyance pipes 5a and 5b are provided with blockage detection devices 7a and 7b. The blockage detectors 7a and 7b detect the blockage of the conveyance pipes 5a and 5b, and input a detection signal to the control device 8. control device 8, blockage detection unit 7a, by entering a detection signal 7b, are to control the opening and closing of the rotation of the drive motor 3 and the on-off valve V 1 and V 1 and V 2 and V 2.

したがって、貯蔵ホッパ１内の粉粒体は、スクリューフィーダ２によって２つの排出口４ａと４ｂのいずれか一方の側から切り出される。この際、いずれの排出口４ａ，４ｂに切り出されるかは、駆動用モータ３の回転によって決定されるようにしてある（たとえば、特許文献１参照）。   Therefore, the granular material in the storage hopper 1 is cut out from either one of the two discharge ports 4 a and 4 b by the screw feeder 2. At this time, which outlet 4a, 4b is cut out is determined by the rotation of the driving motor 3 (see, for example, Patent Document 1).

特開２００１−３１２４５号公報Japanese Patent Laid-Open No. 2001-31245

ところが、上記従来のスクリューフィーダを用いて切出しを行うようにしてあるようなもので、ホッパ内の粉粒体を切り出すようにする場合は、スクリューフィーダのスクリューを押し出し方向へ回転させて定量切出しを行うようにするものであるため、原料が粉体とか粒体の如き流動性のよいものである場合は、スクリューによる押し出しを停止させても自重による自然流れが生じて、流量制御が不可能となるおそれがあり、又、原料が粉体、粒体以外の圧縮性のある原料（たとえば、プラスチック・フレーク等）は、スクリューで押し出されることにより圧縮されて排出口が閉塞するというおそれがある。   However, in the case where the conventional screw feeder is used for cutting, when cutting the powder particles in the hopper, the screw of the screw feeder is rotated in the pushing direction to perform quantitative cutting. Therefore, if the raw material has good fluidity such as powder or granules, the natural flow will occur due to its own weight even if the extrusion by the screw is stopped, and the flow rate control is impossible. In addition, compressible raw materials other than powder and granules (for example, plastic flakes) may be compressed by being extruded with a screw and the discharge port may be blocked.

そこで、本発明は、原料が粉粒状のものでも圧縮性の高いものでも適正に切り出されて搬送させることができるようにする貯蔵容器内原料の切出し方法及び装置を提供しようとするものである。   Therefore, the present invention intends to provide a method and apparatus for cutting out a raw material in a storage container so that the raw material can be appropriately cut out and transported regardless of whether the raw material is powdery or highly compressible.

It is arranged so that it can be rotated by a drive motor, the weight of the raw material discharged from the discharge port is detected, the number of rotations of the screw rotation drive motor is controlled based on the detected value of the weight, and the weight Of cutting out the raw material in the storage container so that there is no change in the storage container, and the raw material in the storage container that cuts out the raw material stored in the storage container from the outlet of the storage container In this cutting device, a screw having a blade attached spirally to the outer peripheral surface of the shaft is arranged in the vertical direction inside the discharge port so that it can be rotated by a drive motor, and A weight detector for detecting the weight of the raw material cut out from the discharge port is provided at the lower part of the cutting and conveying means, and further, the detected value of the raw material weight from the weight detector is inputted, and the rotational speed of the driving motor is Of the raw material in the storage container that controls the number of rotations of the screw so as to eliminate the change in the weight of the raw material cut out from the discharge port and cut out the raw material from the discharge port. A cutting device is used.

又、上記貯蔵容器内原料の切出し方法において、排出口内に位置する原料を下方への押出し方向とは逆の上向きの方向へ持ち上げるようにスクリューを回転させて切出し量を制御させるようにする構成とする。   Further, in the above-described method of cutting out the raw material in the storage container, the cutting amount is controlled by rotating the screw so as to lift the raw material located in the discharge port in the upward direction opposite to the downward pushing direction. To do.

更に、上記貯蔵容器内原料の切出し装置において、排出口の内側に配設したスクリューの羽根の外径と上記排出口の内径との比を０．５〜１．０未満とするようにした構成とする。   Furthermore, in the raw material cutting device in the storage container, the ratio of the outer diameter of the screw blade disposed inside the discharge port and the inner diameter of the discharge port is set to be less than 0.5 to 1.0.

以下、本発明を実施するための最良の形態を図面を参照して説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図１は本発明の実施の一形態を示すもので、貯蔵容器としての貯蔵ホッパ９の下端部に下向きの排出口１０を設け、該排出口１０の下端を、切出し用スクリューコンベヤ１１のケーシング１１ａ途中に接続して、排出口１０とケーシング１１ａ内が連通するようにする。   FIG. 1 shows an embodiment of the present invention. A downward discharge port 10 is provided at a lower end portion of a storage hopper 9 as a storage container, and the lower end of the discharge port 10 is provided as a casing 11a of a screw conveyor 11 for cutting. It connects in the middle so that the discharge port 10 and the inside of the casing 11a communicate.

上記貯蔵ホッパ９の排出口１０の内部には、軸１３の外周面に螺旋状に羽根１４を取り付けてなるスクリュー１２を上下方向に配設すると共に、該スクリュー１２の羽根１４の外径寸法ｄと、排出口１０の内径寸法Ｄとの比が、ｄ／Ｄ≒０．５〜１．０未満程度となるように構成して取扱う原料の粒径が小さいものでは排出口１０と羽根１４との隙間１５が小さいものとし、且つ原料の粒径が大きいときは、上記隙間１５が大きいものとし、該スクリュー１２を駆動用モータ１６により非押出方向、すなわち、排出口１０内の原料を上向きに攪拌させる方向に回転させるようにする。   Inside the discharge port 10 of the storage hopper 9, a screw 12 having a blade 14 spirally attached to the outer peripheral surface of the shaft 13 is disposed in the vertical direction, and the outer diameter d of the blade 14 of the screw 12. In the case where the ratio of the discharge port 10 to the inner diameter D of the discharge port 10 is d / D≈0.5 to less than 1.0 and the particle size of the raw material to be handled is small, the discharge port 10 and the blade 14 When the gap 15 is small and the particle size of the raw material is large, the gap 15 is large, and the screw 12 is driven in the non-extrusion direction by the drive motor 16, that is, the raw material in the discharge port 10 is directed upward. Rotate in the direction of stirring.

更に、上記スクリューコンベヤ１１の途中位置の下側、すなわち、上記排出口１０が接続されるスクリューコンベヤ１１のケーシング１１ａ部の下側に、ケーシング１１ａ内に排出口１０より排出された原料の重量をケーシング１１ａを介して検出できるようにする重量検出器１７を設置して、貯蔵ホッパ９内に貯蔵された原料が排出口１０からスクリューコンベヤ１１のケーシング１１ａ内に排出されたときの原料の重量を重量検出器１７で検出できるようにし、且つ上記重量検出器１７を制御部１８に接続して、ケーシング１１ａ内に排出させられた原料の重量を重量検出器１７で検出すると、その検出値ａを制御部１８に入力させるようにする。   Furthermore, the weight of the raw material discharged | emitted from the discharge port 10 in the casing 11a under the middle position of the said screw conveyor 11, ie, the lower side of the casing 11a part of the screw conveyor 11 to which the said discharge port 10 is connected. A weight detector 17 that enables detection through the casing 11a is installed, and the weight of the raw material when the raw material stored in the storage hopper 9 is discharged from the discharge port 10 into the casing 11a of the screw conveyor 11 is measured. When the weight detector 17 detects the weight of the raw material discharged into the casing 11a by connecting the weight detector 17 to the control unit 18 so that the weight detector 17 can detect the detected value a. Input to the control unit 18.

上記制御部１８は、上記重量検出器１７からの原料重量の検出値ａを入力すると、その検出値ａに基づいて、排出口１０を通過してケーシング１１ａ内に投入された原料の量を求め、且つその量が適正なものであるか否かを、予め定めておいた値との比較で求め、スクリュー１２の駆動用モータ１６へ原料押出し方向とは逆の方向へ回転させる回転数変更の指令を発するようにしてある。   When the detected value a of the raw material weight from the weight detector 17 is input, the control unit 18 obtains the amount of the raw material that has passed through the discharge port 10 and is introduced into the casing 11a based on the detected value a. In addition, whether the amount is appropriate or not is determined by comparison with a predetermined value, and the rotational speed change is performed by rotating the screw 12 to the drive motor 16 in the direction opposite to the raw material extrusion direction. A command is issued.

なお、上記スクリュー１２の軸１３は、図示してないが所要個所が貯蔵ホッパ９に回転できるように支持させてある。１９はスクリューコンベヤ１１のスクリューである。   The shaft 13 of the screw 12 is supported so that a required portion can be rotated by the storage hopper 9 although not shown. Reference numeral 19 denotes a screw of the screw conveyor 11.

なお、又、上記ｄ／Ｄを０．５〜１．０未満としたのは、粒径の大きい原料の場合は隙間１５を大きくとる必要があるが、０．５以下では、粒径の大きい原料も自然流れを起すおそれがあること、又、１．０未満としたのは、粉体状のものでも自然流れし難いようにするためである。   In addition, the d / D is set to be less than 0.5 to 1.0 in the case of a raw material having a large particle size, but it is necessary to make the gap 15 large. The raw material may cause a natural flow, and the reason why the raw material is less than 1.0 is to make it difficult for the raw material to flow naturally even in powder form.

上記のように構成されているので、貯蔵ホッパ９内に貯蔵されている原料を必要とする処理装置へ送るために、貯蔵ホッパ９の排出口１０から順次切り出してスクリューコンベヤ１１で搬送させるようにするときは、貯蔵ホッパ９の排出口１０を通してスクリューコンベヤ１１のケーシング１１ａ内に排出されて落下させられた原料の重量を重量検出器１７で検出し、該重量検出器１７で検出した値ａに基づいて制御部１８からの指令によりスクリュー１２の駆動用モータ１６の回転数を制御するようにし、排出口１０から適正な量の原料が切り出されるようにする。この際、上記スクリュー１２を回転駆動する駆動用モータ１６は、逆回転、すなわち、スクリュー１２により原料を排出口１０内で上方から下方へ押し出す方向とは逆に、原料を排出口１０内で下方から上方へ持ち上げるようにして流動させることができる方向にスクリュー１２を回転駆動させるようにする。又、原料の粒径の大小により、貯蔵ホッパ９内のスクリュー１２の羽根１４の外径ｄと排出口１０の内径Ｄとのｄ／Ｄを、大きくしたものとするとか、小さくしたものとして使用するようにする。   Since it is configured as described above, in order to send the raw material stored in the storage hopper 9 to a processing apparatus that requires it, the material is sequentially cut out from the discharge port 10 of the storage hopper 9 and conveyed by the screw conveyor 11. When the weight is detected, the weight detector 17 detects the weight of the raw material discharged and dropped into the casing 11a of the screw conveyor 11 through the discharge port 10 of the storage hopper 9, and the value a detected by the weight detector 17 is detected. Based on the command from the control unit 18, the rotational speed of the drive motor 16 for the screw 12 is controlled so that an appropriate amount of raw material is cut out from the discharge port 10. At this time, the driving motor 16 for rotationally driving the screw 12 rotates in the reverse direction, that is, in the direction opposite to the direction in which the screw 12 pushes the raw material from the upper side to the lower side in the discharge port 10. The screw 12 is driven to rotate in a direction in which it can be made to flow upward by being lifted upward. Also, depending on the particle size of the raw material, the d / D between the outer diameter d of the blade 14 of the screw 12 in the storage hopper 9 and the inner diameter D of the discharge port 10 is made larger or smaller. To do.

原料の粒径が小さい場合は、図１において、スクリュー１２の羽根１４と貯蔵ホッパ９の排出口１０との隙間１５は小さくしたものを用いるようにし、原料の粒径が大きい場合は、上記隙間１５を或る程度大きくしたものを用いるようにする。   When the particle size of the raw material is small, in FIG. 1, the gap 15 between the blade 14 of the screw 12 and the discharge port 10 of the storage hopper 9 is made small, and when the particle size of the raw material is large, the gap A value obtained by increasing 15 to some extent is used.

図１に示す状態において、貯蔵ホッパ９内のスクリュー１２を駆動用モータ１６により逆方向に回転させると、排出口１０内に堆積されている原料は、スクリュー１２の逆回転により押出し方向とは逆に上方へ持ち上げられるよう流動させられながら、排出口１０内より排出され、スクリューコンベヤ１１のケーシング１１ａ内に落下させられる。該ケーシング１１ａ内に落下させられた原料は、重量検出器１７により重量が検出される。検出された重量の値ａは、重量検出器１７から制御部１８へ信号として入力させられ、該制御部１８で定量の切出し時の重量の設定値と比較され、差があると、設定値と等しくなるように制御部１８から駆動用モータ１６へ指令が送られる。これにより、駆動用モータ１６の回転数が変更制御され、所定の量の切出しが行われるように排出口１０内の原料の流動作用が行われる。   In the state shown in FIG. 1, when the screw 12 in the storage hopper 9 is rotated in the reverse direction by the driving motor 16, the raw material accumulated in the discharge port 10 is opposite to the extrusion direction by the reverse rotation of the screw 12. While being fluidized so as to be lifted upward, the fluid is discharged from the discharge port 10 and dropped into the casing 11 a of the screw conveyor 11. The weight of the raw material dropped into the casing 11 a is detected by the weight detector 17. The detected weight value a is input as a signal from the weight detector 17 to the control unit 18, and is compared with the set value of the weight at the time of cutting out the fixed quantity by the control unit 18. A command is sent from the control unit 18 to the driving motor 16 so as to be equal. As a result, the rotational speed of the drive motor 16 is changed and controlled, and the flow of the raw material in the discharge port 10 is performed so that a predetermined amount is cut out.

この際、原料の粒径が小さい場合は、排出口１０の内側にある原料は、上記隙間１５を通して落下する原料の自然流出量と、スクリュー１２によるバックフローされる量をバランスさせるようにすることにより、定量の切出しを行うことができる。   At this time, if the particle size of the raw material is small, the raw material inside the discharge port 10 balances the natural outflow amount of the raw material falling through the gap 15 and the backflow amount by the screw 12. Thus, it is possible to cut out a certain amount.

又、原料の粒径が大きく且つ圧縮性のあるものでは、貯蔵ホッパ９の排出口１０に導かれた原料は、該排出口１０に詰められることにより圧密されてブリッジ現象や閉塞現象を起すことがあり、かかるブリッジや閉塞が生じると、排出口１０からスクリューコンベヤ１１のケーシング１１ａへの供給量に変動が生じる場合がある。   In addition, when the raw material has a large particle size and is compressible, the raw material introduced to the discharge port 10 of the storage hopper 9 is consolidated by being packed in the discharge port 10 to cause a bridge phenomenon or a clogging phenomenon. When such a bridge or blockage occurs, the supply amount from the discharge port 10 to the casing 11a of the screw conveyor 11 may vary.

かかる場合は、重量検出器１７の信号を制御部１８で入力することにより、ケーシング１１ａへの供給部に供給される原料の重量を検出し、供給量減少になると、スクリュー１２を逆方向へ回転させる回転数を制御して排出口１０内の原料を攪拌するようにして、排出量を増加させるようにして切り出すようにする。   In such a case, the weight of the raw material supplied to the supply unit to the casing 11a is detected by inputting the signal of the weight detector 17 by the control unit 18, and when the supply amount decreases, the screw 12 is rotated in the reverse direction. The number of revolutions is controlled to stir the raw material in the discharge port 10 so as to increase the discharge amount.

なお、本発明は上記実施の形態に限定されるものではなく、たとえば、貯蔵ホッパ９内に配設するスクリュー１２は、軸１３上下方向に延びるように設けてあればよく、鉛直あるいは斜めに設けるようにしてもよく、その他本発明の要旨を逸脱しない範囲内で種々変更を加え得ることは勿論である。   In addition, this invention is not limited to the said embodiment, For example, the screw 12 arrange | positioned in the storage hopper 9 should just be provided so that it may extend in the up-down direction of the axis | shaft 13, and is provided vertically or diagonally. Of course, various modifications may be made without departing from the scope of the present invention.
