Description

本発明は、粉粒体を貯留する貯留設備の切出しシュートからトラックの荷台等に粉粒体を切り出して積載する粉粒体切出し装置に関する。   The present invention relates to a granular material cutting device that cuts and loads a granular material from a cutting chute of a storage facility that stores the granular material on a truck bed or the like.

従来、粉粒体を貯留設備から切り出す方式として、一般的には、図３に示すように貯留設備１の底部にバンカー７を開閉可能に設け、バンカー７の開放により粉粒体を切り出すバンカー方式と、図４に示すように貯留設備１の底部に設けた切出しシュート２から粉粒体を切り出すシュート方式が知られている。   Conventionally, as a method of cutting out the granular material from the storage facility, generally, as shown in FIG. And the chute system which cuts off a granular material from the cut chute 2 provided in the bottom part of the storage facility 1 as shown in FIG. 4 is known.

しかし、バンカー方式ではバンカー７の開放により一気に粉粒体が切り出されるため、粉塵の舞い上がりの問題があった。また、シュート方式では、粉粒体の排出箇所が一定のため、そのままでは粉粒体の受け側であるトラックの荷台６全体に粉粒体を積載ことができず、荷台６全体に粉粒体を積載するにはトラックの荷台６を順次移動させる必要があった。   However, in the bunker system, since the granule is cut out at once by opening the bunker 7, there is a problem of dust rising. Further, in the chute method, since the discharge location of the powder particles is constant, the powder particles cannot be loaded on the entire truck bed 6 on the receiving side of the powder particles as it is, and the powder particles are not loaded on the entire load bed 6. To load the truck, it was necessary to move the truck bed 6 sequentially.

また、特許文献１には、スクリューフィーダを使用した粉粒体切出し装置が開示されているが、この場合も粉粒体の排出箇所が一定のため、シュート方式と同様の問題があった。
特開平６−９２４２９号公報 Further, Patent Document 1 discloses a granular material cutting device using a screw feeder. However, in this case as well, there is a problem similar to the chute method because the discharge position of the granular material is constant.

本発明が解決しようとする課題は、切出し時に粉粒体の舞い上がりが少なく、受け側に粉粒体を均等に積載することができる粉粒体切出し装置を提供することにある。   The problem to be solved by the present invention is to provide a granular material cutting device that can move powder particles evenly on the receiving side with little rise of the granular material during cutting.

本発明の粉粒体切出し装置は、粉粒体を切り出す切出しシュートから荷台に粉粒体を切り出して積載する粉粒体切出し装置において、粉粒体を切り出す切出しシュートの下方に、底部を開放したスクリューフィーダを、該スクリューフィーダの上流側が切出しシュートの直下であって、荷台の前側に位置するように配置し、該スクリューフィーダの下流側の底部に粉粒体の到達を検知する粉粒体検知センサを設け、スクリューフィーダの底部の開口端に、スクリューフィーダによる粉粒体の移送方向に沿ってフラッパーを設け、前記荷台の大きさに応じてフラッパーの傾斜角度を調整可能としたことを特徴とするものである。 The granular material cutting device of the present invention is a granular material cutting device that cuts and loads a granular material on a loading platform from a cutting chute that cuts out the granular material , and opens a bottom portion below the cutting chute that cuts out the granular material . the screw feeder, a directly under the upstream side of the cut shoots of the screw feeder, arranged so as to be positioned on the front side of the loading platform, granular material detection for detecting the arrival of the granular material in the bottom portion of the downstream side of the screw feeder A sensor is provided , and a flapper is provided at the opening end of the bottom of the screw feeder along the transfer direction of the granular material by the screw feeder, and the inclination angle of the flapper can be adjusted according to the size of the loading platform. To do.

このように本発明の粉粒体切出し装置では、切出しシュートから粉体を切り出して排出するので、切出し時の粉粒体の舞い上がりは従来のバンカー方式に比べはるかに少なくなる。切出しシュートから排出された粉粒体はトラックの荷台等の受け側に積載されるが、スクリューフィーダの底部の高さまで積載されると、積載された粉粒体上面をスクリューフィーダの底面としてスクリューフィーダにより下流側に向けて移送される。これによって、受け側を移動させることなく受け側に粉粒体を均等に積載することができる。また、本発明の粉粒体切出し装置ではスクリューフィーダの下流側の底部に粉粒体の到達を検知する粉粒体検知センサを設けているので、この粉粒体検知センサによって受け側に粉粒体がほぼ満載されていることを検知することができる。すなわち、粉粒体検知センサにて粉粒体が検知された時点で粉粒体の切り出しを停止するようにすれば、受け側に粉粒体をほぼ満載の状態で均一に積載することができる。   Thus, in the granular material cutting device of the present invention, the powder is cut out from the cutting chute and discharged, so that the rising of the granular material at the time of cutting is much less than in the conventional bunker system. The granular material discharged from the cutting chute is loaded on the receiving side of the truck bed, etc., but when loaded up to the height of the bottom of the screw feeder, the screw feeder is used with the loaded granular material as the bottom surface of the screw feeder. Is transferred toward the downstream side. As a result, it is possible to load the particles uniformly on the receiving side without moving the receiving side. Further, in the granular material cutting device of the present invention, since the granular material detection sensor for detecting the arrival of the granular material is provided at the bottom of the screw feeder on the downstream side, the granular material is detected on the receiving side by this granular material detection sensor. It can detect that the body is almost full. In other words, if the cutting of the granular material is stopped when the granular material is detected by the granular material detection sensor, the granular material can be uniformly loaded on the receiving side in a substantially full state. .

また、本発明の粉粒体切出し装置では、スクリューフィーダの底部の開口端に、スクリューフィーダによる粉粒体の移送方向に沿ってフラッパーを設け、前記荷台の大きさに応じてフラッパーの開閉度を調整可能としており、このフラッパーの傾斜角度の調整によって、受け側の大きさや粉粒体の性状に応じて適切に粉粒体の積載状況をコントロールできる。 Moreover, in the granular material cutting device of the present invention, a flapper is provided at the opening end of the bottom portion of the screw feeder along the transfer direction of the granular material by the screw feeder, and the degree of opening and closing of the flapper is adjusted according to the size of the loading platform. By adjusting the inclination angle of the flapper, it is possible to appropriately control the loading state of the particles according to the size of the receiving side and the properties of the particles.

以上のとおり、本発明の粉粒体切出し装置によれば、切出し時に粉粒体の舞い上がりが少なく、しかも受け側を移動させることなく、粉粒体を受け側に満載になるまで均等に積載することができる。   As described above, according to the powder particle cutting device of the present invention, the powder particles do not rise at the time of cutting, and the powder particles are loaded evenly on the receiving side without moving the receiving side. be able to.

以下、図面に示す実施例に基づき本発明の実施の形態を説明する。   Embodiments of the present invention will be described below based on examples shown in the drawings.

図１は本発明の粉粒体切出し装置の実施例を示す全体図、図２は図１のＡ−Ａ断面図である。   FIG. 1 is an overall view showing an embodiment of the powder particle cutting device according to the present invention, and FIG.

図１に示すように、粉粒体を貯留する貯留設備１の底部に設けた切出しシュート２の下方に、スクリューフィーダ３が配置されている。スクリューフィーダ３は、図２に示すように、底部が開放したケーシング３ａ内にスクリュー軸３ｂを備えており、スクリュー軸３ｂの回転により粉粒体を上流側から下流側（図１において右側から左側）に向けて移送可能となっている。このスクリューフィーダ３は、その上流側（粉粒体供給口）が切出しシュート２の直下であって、かつ粉粒体の受け側であるトラックの荷台６の前側に位置するように配置される。   As shown in FIG. 1, the screw feeder 3 is arrange | positioned under the cutting chute 2 provided in the bottom part of the storage equipment 1 which stores a granular material. As shown in FIG. 2, the screw feeder 3 includes a screw shaft 3b in a casing 3a having an open bottom, and the powder material is moved from the upstream side to the downstream side by rotating the screw shaft 3b (from the right side to the left side in FIG. 1). ) Can be transported towards. The screw feeder 3 is arranged so that its upstream side (powder particle supply port) is located directly under the cutting chute 2 and on the front side of the truck bed 6 that is the receiving side of the powder particles.

図１に示すように、スクリューフィーダ３の下流側の底部には、粉粒体の到達を検知する粉粒体検知センサとしてリミットスイッチ４が設置されている。このリミットスイッチ４は、トラックの荷台６の後端より僅かに前側に位置するように配置される。リミットスイッチ４は粉粒体に押圧されることにより作動し、リミットスイッチ４が作動すると切出しシュート２からの粉粒体の切り出しが停止され、スクリューフィーダ３の運転も停止される。   As shown in FIG. 1, a limit switch 4 is installed at a bottom portion on the downstream side of the screw feeder 3 as a powder detection sensor that detects the arrival of the powder. The limit switch 4 is arranged so as to be positioned slightly in front of the rear end of the truck bed 6. The limit switch 4 is operated by being pressed by the powder and when the limit switch 4 is operated, the cutting of the powder from the cutting chute 2 is stopped, and the operation of the screw feeder 3 is also stopped.

また、スクリューフィーダ３のケーシング３ａの底部開口両端には、スクリュー軸３ｂの長手方向、すなわち粉粒体の移送方向に沿って可動式のフラッパー５が設けられている。このフラッパー５の開閉度（傾斜角度）は、図示しない制御装置により調整可能とされている。   Moreover, the movable flapper 5 is provided in the bottom opening both ends of the casing 3a of the screw feeder 3 along the longitudinal direction of the screw shaft 3b, that is, the transfer direction of the granular material. The degree of opening / closing (inclination angle) of the flapper 5 can be adjusted by a control device (not shown).

以上の構成において、切出しシュート２から排出された粉粒体は、まず、切出しシュート２直下の荷台６に積載される。その後、積載された粉粒体上面がスクリューフィーダ３の底部の高さまで到達すると、粉粒体はその上面をスクリューフィーダ３の底面として、スクリューフィーダ３により下流側に向けて移送される。このとき、粉粒体の下流側への移送範囲は、フラッパー５の開閉度により調整することができ、荷台６の大きさや粉粒体の性状に応じてフラッパー５の開閉度を調整し粉粒体の積載状況をコントロールする。そして、下流側に移送された粉粒体がリミットスイッチ４の位置まで到達して荷台６が満載の状態となると、リミットスイッチ４が作動し、切出しシュート２からの粉粒体の切出し、及びスクリューフィーダ３の運転が停止される。   In the above configuration, the granular material discharged from the cutting chute 2 is first loaded on the loading platform 6 immediately below the cutting chute 2. Thereafter, when the upper surface of the loaded granular material reaches the height of the bottom of the screw feeder 3, the granular material is transferred toward the downstream side by the screw feeder 3 with the upper surface as the bottom surface of the screw feeder 3. At this time, the transport range to the downstream side of the granular material can be adjusted by the opening / closing degree of the flapper 5, and the opening / closing degree of the flapper 5 is adjusted according to the size of the loading platform 6 and the properties of the granular material. Control the loading status of the body. Then, when the granular material transferred to the downstream side reaches the position of the limit switch 4 and the loading platform 6 is fully loaded, the limit switch 4 is activated, and the granular material is cut out from the cutting chute 2 and the screw. The operation of the feeder 3 is stopped.

本発明は、細破砕されたプラスチックなど各種の粉粒体の切出しに利用可能である。   The present invention can be used for cutting out various powder particles such as finely crushed plastic.
