〔産業上の利用分野〕
本発明は、粉・粒体を収納した可撓容器の排出方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for discharging a flexible container containing powder or granules.
ポリエチレン、ポリ塩化ビニル等の容器は、小量の取扱
いではクラフト紙を数枚重ねた袋が用いられ、大量の取
り扱いではアル逅ニウムコンテナーが用いられているが
、アルもニウムコンテナーでは、中味が消費されて空に
なってもその大きさを小さくできないので、コンテナー
の返却輸送経費が節約できない。Containers for polyethylene, polyvinyl chloride, etc. are used in bags made of several layers of kraft paper for handling small quantities, and aluminum containers are used for handling large quantities. Even if the container is consumed and emptied, its size cannot be reduced, so the cost of returning the container cannot be saved.
そこで、この対策として近年強度の極めて高い繊維例え
ばアラミド繊維などを用いた大型の袋状をした可撓容器
（フレキシブルコンテナーといわれている）が盛んに使
用されるようになって来た。As a countermeasure against this problem, in recent years, large bag-shaped flexible containers (referred to as flexible containers) made of extremely strong fibers such as aramid fibers have come into widespread use.
このフレキシブルコンテナー（以下、フレ・コンという
、）は、返却輸送の際は嵩が小さくなって大変便利であ
るが、フレ・コン内部を目視できないこと、内部樹脂が
取り出されて減ってくると気ままな形で折れ曲がりその
折曲場所（空所）に樹脂粉粒が残って、樹脂粉粒を完全
に排出できないような状態になる。特に、粒体はこの傾
向が高い、少量扱いの袋であれば袋を持ってはたけば良
いが、フレ・コンのように大きくなると思うようにでき
ない。This flexible container (hereinafter referred to as a flexible container) is very convenient because its bulk is small when returning it, but it is difficult to see inside the flexible container, and once the resin inside is removed and reduced It bends in such a way that resin powder particles remain in the bent place (empty space), resulting in a situation where the resin powder particles cannot be completely discharged. This tendency is particularly high for granules.If the bag is for small quantities, you can just hold the bag and flap it around, but if it's large like a flexible container, you won't be able to do it as you want.
そこで、本発明は、フレ・コンのような大きな可撓容器
でも、その収容物・粒体を円滑に排出できるようにする
ことを課題とする。Therefore, it is an object of the present invention to enable even large flexible containers such as flexible containers to smoothly discharge the contents and particles contained therein.
上記課題を解決するために、本発明にあっては、内部に
粉・粒体が満杯の可撓容器をホッパーの上に置き、その
下部排出口を開き、該可撓容器の上部に、ケーブルワイ
ヤを延設したフックを掛合して、該ケーブルワイヤを上
方に引き上げ、その方向を、シーブを介して反転し下向
きにしてその終端に可撓容器の重量（内容物重量を含ま
ない）より少し重いカウンターウェイトを吊し、そのカ
ウンターウェイトにより、可撓容器上部を上方に引き上
げながら前記粉・粒体を排出するようにしたのである。In order to solve the above problems, in the present invention, a flexible container filled with powder/granules is placed on a hopper, the lower discharge port is opened, and a cable is connected to the upper part of the flexible container. Engage the hook with the wire extension, pull the cable wire upwards, reverse its direction through the sheave and point it downwards so that its end is less than the weight of the flexible container (not including the weight of the contents). A heavy counterweight is suspended, and the powder/granules are discharged while lifting the upper part of the flexible container upward.
この排出時、可撓容器内の粉・粒体終量直前に、バイブ
レータにより、可撓容器を振動させるとよい。During this discharge, it is preferable to vibrate the flexible container with a vibrator just before the amount of powder/granules in the flexible container is finished.
このように構成される排出方法は、カウンターウェイト
により、可撓容器上部を上方に引き上げながら粉・粒体
を排出するため、可撓容器が気ままな形に折れ曲がるこ
とがない。In the discharge method configured in this manner, the powder/granules are discharged while the upper part of the flexible container is pulled upward by a counterweight, so that the flexible container does not bend into an arbitrary shape.
バイブレータにより、綿量直前に可撓容器を振動させれ
ば、仮に折れ曲がって、その折曲場所に粉・粒体が残っ
ていても、その振動によって落下する。If the flexible container is vibrated with a vibrator just before the cotton is weighed, even if it bends and powder/granules remain at the bend, the vibration will cause it to fall.
この実施例は、電線・ケーブルの製造工程における外被
押出成形機への外被用樹脂供給部に採用したものであり
、図に示すように、フレームＦにホッパー１が設けられ
、このホッパー１下方に樹脂台車２が位置されている。This embodiment is adopted for the outer sheathing resin supply part to the outer sheathing extrusion molding machine in the manufacturing process of electric wires and cables.As shown in the figure, a hopper 1 is provided on the frame F, and this hopper 1 A resin truck 2 is located below.
この樹脂台車２には吸引管３が挿入され、この吸引管３

して押出成形機（図示せず）に搬送される。A suction pipe 3 is inserted into this resin cart 2, and this suction pipe 3
Then, the resin a in the truck 2 is conveyed to an extrusion molding machine (not shown) via a flexible tube 4.

イトＣＷは、フレ・コンＣの空重量より少し重いもので
、その荷重により、同図鎖線で示すように、フレ・コン
Ｃ上部が上方に引き上げられる。A flexible container C is placed on the hopper 1, and a hook 5 is secured to the upper part of the flexible container C.
A cable wire 6 extends upwardly from the suspension ring 8;
After passing through a vibrator 9, the wire 6 is directed downward by a sheave 7, and a counterweight CW is provided at the end thereof. This counterweight CW is slightly heavier than the empty weight of the flexible computer C, and its load causes the upper part of the flexible computer C to be pulled upward as shown by the chain line in the figure.

ャックが作動してケーブルワイヤ６を挟持するとともに
モータが作動し、チャックが横方向に揺れてケーブルワ
イヤ６を介してフレ・コンＣが振動する。The vibrator 9 has a chuck that clamps the cable wire 6 and a motor that rotates the chuck eccentrically.The chuck is activated by a detection signal from a switch SW1, which will be described later, to clamp the cable wire 6 and the motor is activated. When activated, the chuck swings laterally and the flexible container C vibrates via the cable wire 6.
したがって、押出成形機に樹脂ａが送り込まれて、フレ
・コンＣ内の樹脂ａが台車２内に落下し、その量が減少
すると、同図鎖線で示すように、フレ・コンＣ上部は徐
々に上方に引き上げられてカウンターウェイトＣＷも下
降する。Therefore, when the resin a is fed into the extrusion molding machine and the resin a in the flexible container C falls into the trolley 2 and its amount decreases, the upper part of the flexible container C gradually drops as shown by the chain line in the figure. The counterweight CW is also lowered by being pulled upward.
フレ・コンＣ内が綿量直前になると、その直前時のカウ
ンターウェイトＣＷの位置を近接スイッチＳＷｌが検知
し、その検知信号により、バイブレータ９が作動してフ
レ・コンＣが振動し、内部の樹脂ａが振い落される。When the inside of the flexible container C is just before the amount of cotton, the proximity switch SWl detects the position of the counterweight CW just before that time, and the detection signal activates the vibrator 9 to vibrate the flexible container C, causing the inside of the flexible container C to vibrate. Resin a is shaken off.

ッチＳＷｚがそのカウンターウェイ）ＣＷを検知して、
その検知信号でもってブザーが鳴呼又はランプが点滅し
て報知される。Subsequently, when the inside of the flexible container C becomes dry, the counterweight CW greatly descends, passes in front of the proximity switch SW2, and reaches the top of the frame (not shown). At this time, switch SWz detects its counterway) CW,
The detection signal is notified by a buzzer or a flashing lamp.
この報知により、作業者はフレ・コンＣの綿量を知り、
満杯の新たなフレ・コンＣと取り替える。With this notification, the worker knows the cotton content of flexible container C.
Replace it with a new, full FIBC C.

付は、フレ・コンＣの容量・形状等に応じて上下所要位
置に移動固定できるようにするとよい。For the switches SW1 and SW2, various well-known devices such as a photo sensor can be used in addition to the proximity switch, and their installation can be done in such a way that they can be moved and fixed at desired positions up and down depending on the capacity, shape, etc. of the flexible container C. good.
上記バイブレータ９は、前記の構成以外に、吊り環８を
電動プランジャーでたたく等の種々の周知の構成のもの
とすることができる。The vibrator 9 can have various known configurations other than the configuration described above, such as striking the hanging ring 8 with an electric plunger.
本願発明は、以上のように構成したので、可撓容器から
粉・粒体を円滑かつ確実に排出できる。Since the present invention is configured as described above, powder and granules can be smoothly and reliably discharged from the flexible container.
このため、可撓容器内に粉・粒体が残って未使用のまま
返却させることがなくなり、生産コストの低減を図るこ
とができる。Therefore, powder and granules will not remain in the flexible container and the container will not be returned unused, and production costs can be reduced.
