前記した従来の粉粒体収容袋開封装置には次のような問題点がある。
前記の袋底の開封装置においては、開封時にセメントが粉塵となって飛び散ることをある程度は回避可能であったが、完全には回避し得なかった。
従来技術では、袋体をホッパ上部に位置決めした状態で開封するため、袋体から排出される粉粒体が周囲に飛び散ることをある程度は抑えることができた。
しかし、依然としてホッパと袋体が完全に密着するものではないため、ホッパと袋体との隙間部から開封時に舞い上がったコンクリート等の粉塵の飛び散りを完全に抑えることができなかった。
飛び散った粉塵は周辺の汚れや、作業環境の悪化、人体への悪影響はもちろん、大型プラント内ではセメント等を処理する量も多く、飛び散りによるセメントのロスが大きなものであった。 The above-described conventional granular material containing bag opening device has the following problems.
In the above-described bag bottom opening device, it was possible to avoid cement scattering to a certain extent at the time of opening, but it could not be completely avoided.
In the prior art, since the bag is opened with the bag positioned in the upper part of the hopper, the powder discharged from the bag can be suppressed to a certain extent.
However, since the hopper and the bag are not completely in close contact with each other, it has not been possible to completely suppress the scattering of dust, such as concrete, that has risen from the gap between the hopper and the bag.
Scattered dust was not only dirty in the surroundings, worsened working environment, and adverse effects on the human body, but also a large amount of cement was treated in large plants, and the loss of cement due to scattering was great.

本発明は、前述したようなセメント等の粉塵の周囲への飛び散りを完全に無くし、周辺の汚れ、人体への悪影響を防ぎ作業環境を良好に保持するとともに、飛び散る粉粒体のロスを無くすことにより経済性を有した装置を提供することを目的としている。   The present invention completely eliminates the scattering of dust such as cement as described above, prevents the surrounding dirt and adverse effects on the human body, maintains a good working environment, and eliminates the loss of scattered powder particles. It aims at providing the apparatus which was more economical.

上記した課題を達成するため、本願の第１発明に係る粉粒体収容袋開封装置は、上部を開口し、粉粒体収容袋を収容しうる径を有するホッパと、ホッパ内部空間に配置した発熱体と、粉粒体収容袋と密着し、ホッパの円周方向に沿って配置した可撓性の袋である防塵帯とより構成したことを特徴とするものである。
本願の第２発明に係る粉粒体収容袋開封装置は、前記した第１発明において、防塵帯を膨張収縮可能に構成し、防塵帯が、防塵帯内部に流体を供給することで膨張することを特徴とするものである。
本願の第３発明に係る粉粒体収容袋開封装置は、前記した第２発明において、防塵帯の上を覆い、可撓性を有する保護材を設けたことを特徴とするものである。 In order to achieve the above-described problem, the powder container containing bag opening device according to the first invention of the present application is arranged in a hopper having a diameter that can open the top and accommodate the powder material containing bag, and the hopper internal space. It is characterized by comprising a heating element and a dustproof band which is a flexible bag that is in close contact with the granular material containing bag and is disposed along the circumferential direction of the hopper.
The granular material storage bag opening device according to the second invention of the present application is the first invention described above, wherein the dustproof zone is configured to be able to expand and contract, and the dustproof zone expands by supplying a fluid to the inside of the dustproof zone. It is characterized by.
The granular material accommodation bag opening apparatus which concerns on 3rd invention of this application WHEREIN: In above-mentioned 2nd invention, it covered the dust-proof zone and provided the protective material which has flexibility, It is characterized by the above-mentioned.

以上説明したように、本発明によれば、少なくとも次のいずれかひとつの効果を得ることができる。
（１）前述したように構成したことにより、粉粒体収容袋開封時に粉粒体収容袋と、ホッパに設けた防塵帯が完全に密着するため、セメントの粉塵は粉粒体収容袋とホッパの隙間から外部へ飛び散ることが無く粉粒体収容袋からホッパへセメント等の粉粒体を移し替えることが出来る。
袋体から排出される粉粒体が周囲に飛び散ることがないため、排出される粉粒体による作業員への悪影響や周囲の環境が汚れることを防止できる。
（２）前述したように構成した事により、袋体から粉粒体を排出するに際して人手で袋を破る必要が無いので、作業員への悪影響が無くなると共に、粉粒体を排出する作業を容易に行うことができ、開封機構の構成を簡素化することが出来る。 As described above, according to the present invention, at least one of the following effects can be obtained.
(1) Since the powder storage bag and the dustproof band provided on the hopper are completely in close contact with each other when the powder storage bag is opened, the dust of the cement is stored in the powder storage bag and the hopper. The granular material such as cement can be transferred from the granular material containing bag to the hopper without scattering from the gap.
Since the granular material discharged from the bag body does not scatter around, it is possible to prevent the discharged granular material from adversely affecting workers and contaminating the surrounding environment.
(2) Since it is configured as described above, it is not necessary to manually break the bag when discharging the powder from the bag, so there is no adverse effect on the worker and the work for discharging the powder is easy. The structure of the opening mechanism can be simplified.

＜使用方法＞
セメントや粉粒体を受けるホッパ３を準備する。ホッパ３は内部に発熱体２を設置したものであり上部が開口したものである。
ホッパ３上部の径はセメントや粉粒体を充填した、吊具５を有する粉粒体収容袋４が十分に収容可能な径の大きさとする。また、粉粒体収容袋４の底部がホッパ３内の発熱体２上にまで吊下げられた時に、防塵帯１が粉粒体収容袋４と密着するような位置に、防塵帯１を設置する。また、防塵帯１はホッパ３内部の発熱体２よりも上部に設置しておく。
吊具５によりホッパ３内部へ吊下げられた粉粒体収容袋４は底部が発熱体２に接することになる。
この時点で、粉粒体収容袋４と防塵帯１とは密着し隙間の無い状態となっている。
粉粒体収容袋４の底部はあらかじめ、溶熱性部材で構成してあるため、発熱体２の起動スイッチを入れ溶融温度以上に発熱体２の温度が上昇すると、粉粒体収容袋４の底部は熱切断されて、粉粒体収容袋４の底部が開口する。
開口した粉粒体収容袋４の底部からセメント等の粉粒体が流出するが、ホッパ３と粉粒体収容袋４が密着し、間に隙間がないため、セメント等粉粒体のホッパ３からの漏れ出しが無く、ホッパ外部にセメント等の粉粒体が飛び散らない。 <How to use>
A hopper 3 for receiving cement and powder is prepared. The hopper 3 has the heating element 2 installed therein, and has an open top.
The diameter of the upper part of the hopper 3 is set to a diameter that can be sufficiently accommodated in the powder-containing bag 4 filled with cement or powder and having the hanging tool 5. In addition, the dustproof belt 1 is installed at a position where the dustproof belt 1 comes into close contact with the granular material housing bag 4 when the bottom of the powder carrier bag 4 is suspended to the heating element 2 in the hopper 3. To do. Further, the dustproof belt 1 is installed above the heating element 2 inside the hopper 3.
The granular material containing bag 4 suspended inside the hopper 3 by the hanging tool 5 comes into contact with the heating element 2 at the bottom.
At this time, the granular material containing bag 4 and the dustproof belt 1 are in close contact with each other and there is no gap.
Since the bottom part of the granular material storage bag 4 is composed of a heat-melting member in advance, when the start-up switch of the heating element 2 is turned on and the temperature of the heating element 2 rises above the melting temperature, the bottom part of the granular material storage bag 4 Is heat-cut and the bottom of the powder-containing bag 4 is opened.
Cement or other granular material flows out from the bottom of the opened granular material containing bag 4, but since the hopper 3 and the granular material containing bag 4 are in close contact with each other and there is no gap between them, the cement and other granular material hopper 3 There is no leakage from the hopper, and powder particles such as cement do not scatter outside the hopper.

防塵帯１は、膨張収縮可能に構成することも可能である。
例えば、防塵帯１に流体を送り込むパイプ等を結合し、パイプの他端には、流体送圧ポンプ６に結合する。
粉粒体収容袋４がホッパ３に収容される前は、防塵帯１内部の流体を取り出し縮んだ状態にしておく（図３参照）。
そして、粉粒体収容袋４の底部が発熱体２に接した位置にて、流体送圧ポンプ６を作動させ、流体を防塵帯１に送り込む。これにより防塵帯１に流体が充填し、防塵帯１が膨張するとともに、防塵帯１と粉粒体収容袋４とが密着する。
粉粒体収容袋４から取り出されるセメント等の粉粒体が飛び散らない程に密着した時点で流体送圧ポンプ６による防塵帯１内の流体圧力を一定に維持し、発熱体２を発熱させ粉粒体収容袋４の底部を熱切断し開封する（図４参照）。
また、ホッパ３内周面にセンサを取り付け、粉粒体収容袋４の吊下げ位置に反応し、粉粒体収容袋が発熱体近くに吊下げられた時点で、自動的に流体を防塵帯１へ送り込むように構成してもよい。
センサは流体の防塵帯１への送り込みだけでなく、粉粒体収容袋４の指定位置への収容により発熱体４の自動発熱などとも連動するように構成する事もできる。 The dustproof belt 1 can also be configured to be able to expand and contract.
For example, a pipe or the like that feeds fluid to the dustproof zone 1 is coupled, and the other end of the pipe is coupled to the fluid pressure pump 6.
Before the granular material storage bag 4 is stored in the hopper 3, the fluid inside the dustproof belt 1 is taken out and kept in a contracted state (see FIG. 3).
Then, the fluid pressure pump 6 is operated at a position where the bottom of the granular material containing bag 4 is in contact with the heating element 2 to feed the fluid into the dustproof zone 1. As a result, the dust-proof zone 1 is filled with fluid, the dust-proof zone 1 expands, and the dust-proof zone 1 and the powder-containing body bag 4 are in close contact with each other.
When the powder such as cement taken out from the powder container 4 is in close contact with the powder, the fluid pressure in the dustproof zone 1 by the fluid pressure pump 6 is maintained constant, and the heating element 2 is heated to generate powder. The bottom of the granule containing bag 4 is thermally cut and opened (see FIG. 4).
Further, a sensor is attached to the inner peripheral surface of the hopper 3, reacts with the suspended position of the granular material storage bag 4, and when the granular material storage bag is suspended near the heating element, the fluid is automatically removed from the dustproof zone. You may comprise so that it may send in to 1.
The sensor can be configured not only to feed the fluid into the dust-proof zone 1 but also to interlock with automatic heat generation of the heating element 4 by accommodating the granular material accommodation bag 4 at a designated position.

防塵帯１が縮んだ状態で粉粒体収容袋４を収容する際に、防塵帯１が粉粒体収容袋４のホッパ３への収容時にホッパ３内部へ巻き込まれてしまう場合がある。
ここで、防塵帯１をガードするように、防塵帯１の上部を覆うカーテン状の保護材をホッパ３に取り付ける。
保護材は可撓性の布などで構成し、防塵帯１の上を覆うように配置し、保護材の上部は固定し下部は開放に形成し、防塵帯１の膨張収縮に対応可能な構成とする。
また、保護材上部をフリップ状の上下可動式にしてホッパ３に取り付ける構成も可能である。
保護材は、保護材により覆う防塵帯１を粉粒体収容袋４の重み等から防御するためのものであるので、構成する部材はホッパ３への接続部や保護材自体が相応の引張り強度を持っている事が必要となる。
保護材の大きさは、防塵帯１が膨張した際には防塵帯１自体が直接に粉粒体収容袋４に密着するサイズに構成することも、可撓性を有するため保護材が粉粒体収容袋４に密着するように構成することも可能である。
保護材は、ホッパ３内全周に取り付けるものでも、防塵帯１に係る荷重に応じてホッパ３に部分的に取り付けるものでも構成可能である。
保護材が防塵帯１の上を覆うように設置したことで、粉粒体収容袋４のホッパ３への収容時に、防塵帯１と粉粒体収容袋４との直接の摩擦を回避し、ホッパ３から防塵帯１が取り外れるのを防ぐことができる。 When the granular material storage bag 4 is stored in a state where the dustproof belt 1 is contracted, the dustproof belt 1 may be caught inside the hopper 3 when the granular material storage bag 4 is stored in the hopper 3.
Here, a curtain-like protective material that covers the upper portion of the dustproof belt 1 is attached to the hopper 3 so as to guard the dustproof belt 1.
The protective material is made of a flexible cloth, and is arranged so as to cover the dust-proof band 1. The protective material is fixed at the upper part and open at the lower part, so that it can cope with expansion and contraction of the dust-proof band 1. And
Moreover, the structure which attaches to the hopper 3 by making the upper part of a protective material into a flip-shaped vertically movable type is also possible.
Since the protective material is for protecting the dust-proof belt 1 covered with the protective material from the weight of the granular material containing bag 4 and the like, the components constituting the connecting portion to the hopper 3 and the protective material itself have an appropriate tensile strength. It is necessary to have
The size of the protective material may be configured such that when the dust-proof belt 1 expands, the dust-proof belt 1 itself is in close contact with the powder-containing bag 4. It is also possible to configure so as to be in close contact with the body containing bag 4.
The protective material can be configured to be attached to the entire circumference of the hopper 3 or to be partially attached to the hopper 3 in accordance with the load applied to the dustproof belt 1.
By installing the protective material so as to cover the dust-proof belt 1, when the powder-containing bag 4 is accommodated in the hopper 3, direct friction between the dust-proof belt 1 and the powder-containing bag 4 is avoided. It is possible to prevent the dustproof belt 1 from being removed from the hopper 3.
