Description

本発明は、粉体や粒体などの貯留物を内部に貯留するホッパー及びその下端部に設けられる排出装置に関し、特にホッパー下端部に設けた排出口から貯留物を外部に支障なく排出することができる新規なホッパー及び排出装置に関する。   TECHNICAL FIELD The present invention relates to a hopper for storing a stored substance such as powder and granules, and a discharge device provided at the lower end of the hopper, and in particular, discharging the stored substance to the outside from an outlet provided at the lower end of the hopper. The present invention relates to a new hopper and a discharge device that can be used.

上述したホッパーとしては、図４に示すように下部１０１がすり鉢状に形成されるとともにその下端に排出口１０２が形成されたホッパー本体１００と、ホッパー本体１００の下端部１００ａに、外部からの駆動により上下動することで前記排出口１０２を開閉可能に塞ぐ上側が尖った円錐形状の開閉部材１０３とが設けられたものが知られている（例えば特許文献１等参照）。上記開閉部材１０３は、板材を円錐形状に加工したものからなり、下面側（裏側）には上側が尖った円錐形状の空洞が形成されている。   As the hopper described above, as shown in FIG. 4, the lower part 101 is formed in a mortar shape and the discharge port 102 is formed at the lower end thereof, and the lower end part 100a of the hopper main body 100 is driven from the outside. It is known that a conical opening / closing member 103 with a sharp upper side that closes the discharge port 102 so as to be opened and closed by moving up and down is provided (see, for example, Patent Document 1). The opening / closing member 103 is formed by processing a plate material into a conical shape, and a conical cavity with a sharp upper side is formed on the lower surface side (back side).

このホッパーの開閉部材１０３の開閉は、以下のようにして行われる。まず、図４及び図５に示すように、ホッパーを固定部１１０に載せるとともに、固定部１１０に昇降可能に設けられ開閉部材１０３と同様の上側が尖った円錐形状に形成された昇降部材１１１の上に開閉部材１０３を配置する。その後、上記昇降部材１１１を昇降させ、その昇降部材１１１で開閉部材１０３を上下動させることにより行われる。例えば昇降部材１１１を上昇させると開閉部材１０３が上昇して排出口１０２を開状態にし、逆に昇降部材１１１を下降させると開閉部材１０３が下降して排出口１０２を閉状態にする。   The hopper opening and closing member 103 is opened and closed as follows. First, as shown in FIGS. 4 and 5, the hopper is placed on the fixed portion 110, and the lift member 111 is provided in the fixed portion 110 so as to be movable up and down and is formed in a conical shape with a sharp upper side similar to the opening / closing member 103. The opening / closing member 103 is disposed on the top. Thereafter, the lifting / lowering member 111 is moved up and down, and the opening / closing member 103 is moved up and down by the lifting / lowering member 111. For example, when the elevating member 111 is raised, the opening / closing member 103 is raised and the discharge port 102 is opened. Conversely, when the elevating member 111 is lowered, the opening / closing member 103 is lowered and the discharge port 102 is closed.

特許公報第２６６０３０５号Patent Publication No. 2660305

ところで、従来のホッパーにあっては、円錐形状をした開閉部材１０３の裏側における周縁に環状壁部１０３ａが垂下状態に設けられ、一方、固定部１１０には昇降部材１１１が設けられており、この昇降部材１１１は、上昇のときに環状壁部１０３ａの内側に入り、降下のときに一定高さ以上に降下したときに環状壁部１０３ａから離れる。つまり、昇降部材１１１と環状壁部１０３ａとは、開閉部材１０３の開閉に際して互いに摺動することにより、開閉部材１０３を所定の水平位置に案内する案内手段としても機能する。これは、ホッパー本体１００と、ホッパーの開閉部材１０３を開閉させる固定部１１０とが、別体として設けられているため、開閉部材１０３の近傍に案内手段を必要とするからである。   By the way, in the conventional hopper, the annular wall portion 103a is provided in a suspended state at the periphery on the back side of the conical opening and closing member 103, while the elevating member 111 is provided in the fixed portion 110. The elevating member 111 enters the inside of the annular wall 103a when ascending, and moves away from the annular wall 103a when descending to a certain height or more when descending. That is, the elevating member 111 and the annular wall 103a also function as guide means for guiding the opening / closing member 103 to a predetermined horizontal position by sliding with each other when the opening / closing member 103 is opened and closed. This is because the hopper main body 100 and the fixing portion 110 for opening and closing the hopper opening / closing member 103 are provided as separate bodies, and thus a guide means is required in the vicinity of the opening / closing member 103.

そして、昇降部材１１１が上昇して環状壁部１０３ａに案内されて環状壁部１０３ａの内側に入った後に開閉部材１０３が上昇すると、排出口１０２が開状態になって貯留物が排出される。この排出のとき、昇降部材１１１と環状壁部１０３ａとの隙間に貯留物が入り得る。その後、貯留物の排出が完了して、昇降部材１１１が降下して環状壁部１０３ａから離れることで、前記隙間の貯留物が落下するものの、一部が昇降部材１１１の外面や環状壁部１０３ａの内面に付着して残る虞がある。このようにして貯留物が残った場合には、次の貯留物を排出するときに、残っていた前回排出の貯留物が混じるという難点があった。   When the elevating member 111 is raised and guided by the annular wall portion 103a and enters the inside of the annular wall portion 103a, when the opening and closing member 103 is raised, the discharge port 102 is opened and the stored matter is discharged. At the time of this discharge, a reservoir can enter the gap between the elevating member 111 and the annular wall portion 103a. Thereafter, the discharge of the storage is completed, and the lifting member 111 is lowered and separated from the annular wall 103a, so that the storage in the gap falls, but a part of the outer surface of the lifting member 111 and the annular wall 103a. There is a risk that it will remain attached to the inner surface. In the case where the stored matter remains in this way, there is a problem that when the next stored matter is discharged, the remaining discharged stored matter is mixed.

本発明は、このような従来技術の課題を解決するためになされたものであり、貯留物が混じることを防ぐことが可能なホッパー及び排出装置を提供することを目的とする。   This invention is made | formed in order to solve such a subject of a prior art, and it aims at providing the hopper and discharge device which can prevent a storage material mixing.

本発明のホッパー及び排出装置による場合には、ホッパー本体の下端部に排出装置が取付けられてホッパー本体と排出装置が一体化されており、しかも排出口を開閉する開閉部を有する昇降部材の軸部が軸受部により昇降可能に支持されているので、開閉部の近傍において従来必要としていた互いに摺動する機構の案内手段を省略することが可能となり、これに伴って案内手段に付着して貯留物が残ることを防止することができ、これにより貯留物が混じることを防ぐことが可能になる。加えて、本発明にあっては、ホッパー本体の下端部に取付けられた排出装置が排出口及び枠体の鉛直孔の内側を昇降可能な昇降部材を備え、その昇降部材における開閉部とその下側の鉛直孔の下端開口部を囲む枠体の周縁部とに亘って被覆膜が設けられており、また軸受部が枠体よりも下側に配設されているので、昇降部材の開閉部以下の部分及び軸受部と貯留物を排出する通路とが被覆膜により区分される。よって、昇降部材の開閉部以下の部分及び軸受部に貯留物が付着せずに残らないようにすることができる。更に、加えて被覆膜が低摩擦性のフッ素樹脂からなるため、被覆膜自身にも貯留物の付着がない。その結果、このことによっても貯留物が混じることを防止することが可能となる。更に、開閉部が排出口よりも上側に位置する構成であるので、仮に貯留物が棚吊りになっていても、昇降部材を昇降させて、その棚吊りとなっている貯留物の部分を上方に押し上げることにより、棚吊りを崩すことができる。ここで、棚吊りとは、貯留物がホッパー本体の内部で固まる等により落下しなくなる、または落下し難くなることを言う。   In the case of the hopper and discharge device of the present invention, the discharge device is attached to the lower end of the hopper body, the hopper body and the discharge device are integrated, and the shaft of the lifting member having an opening / closing portion that opens and closes the discharge port Since the part is supported by the bearing part so as to be able to move up and down, it is possible to omit the guide means of the mechanism that slides in the vicinity of the opening and closing part, which is necessary in the past. It is possible to prevent an object from remaining, and thus it is possible to prevent the stored material from being mixed. In addition, according to the present invention, the discharge device attached to the lower end portion of the hopper body includes an elevating member that can elevate and lower the inside of the vertical opening of the discharge port and the frame body, Since the coating film is provided over the peripheral edge of the frame body surrounding the lower end opening of the vertical hole on the side, and the bearing portion is disposed below the frame body, the elevating member can be opened and closed. The part below the part and the bearing part and the passage for discharging the stored material are separated by the coating film. Therefore, it is possible to prevent the deposit from adhering to the portion below the opening / closing portion of the elevating member and the bearing portion. In addition, since the coating film is made of a low-friction fluororesin, the coating film itself has no deposits. As a result, this also makes it possible to prevent the stored matter from being mixed. Further, since the opening / closing part is located above the discharge port, even if the stored item is shelf-suspended, the lifting member is moved up and down, and the portion of the stored item that is suspended from the shelf is By pushing it up, the shelf suspension can be broken. Here, suspending the shelf means that the stored material does not fall or becomes difficult to fall due to solidification inside the hopper body.

請求項２の発明による場合には、棚吊りを崩すべく開閉部の上に設けた棚吊り崩し部が金属製であるので、棚吊り崩し部に傷が付くことを防止することができる。このとき、請求項４のように、開閉部とその上側の棚吊り崩し部とを別体のもので構成し、これらの間において被覆膜の上端を固定するようにすることで、棚吊りを崩すときに被覆膜が傷付くことを防止することが可能になる。   According to the second aspect of the present invention, since the shelf hanging breaker provided on the opening / closing part to break the shelf hanging is made of metal, it is possible to prevent the shelf hanging breaker from being damaged. At this time, as described in claim 4, the opening / closing part and the shelf suspending part on the upper side thereof are configured separately, and the upper end of the coating film is fixed between them, thereby suspending the shelf It is possible to prevent the coating film from being damaged when breaking down.

請求項７の発明による場合には、排出管が斜め下向きに延びているので、貯留物を排出孔から残すことなく排出管を介して外部へ排出することができる。   According to the seventh aspect of the invention, since the discharge pipe extends obliquely downward, the stored matter can be discharged to the outside through the discharge pipe without leaving the discharge hole.

軸部１６は、鉛直孔１１ａを挿通し、更にその下側部分が軸受部１２の前記軸受孔１２ａに挿通するとともに軸受部１２に昇降可能に支持されている。また軸部１６は、軸受部１２よりも下側に延出しており、その延出部分が駆動手段１４からの昇降駆動力を受けるように構成されている。上記軸受部１２には軸部１６との間をシールするシール部材１２ｄ、１２ｅが設けられており、軸部１６のシール部材１２ｄ、１２ｅでシールされた部分よりも上側には、排出口３が開のときに、被覆膜１７の下部を湾曲させる突状部材１２ｆが固設されている。   The shaft portion 16 is inserted through the vertical hole 11a, and the lower portion thereof is inserted into the bearing hole 12a of the bearing portion 12 and supported by the bearing portion 12 so as to be movable up and down. Further, the shaft portion 16 extends below the bearing portion 12, and the extending portion is configured to receive the lifting drive force from the driving means 14. The bearing portion 12 is provided with seal members 12d and 12e for sealing between the shaft portion 16, and the discharge port 3 is disposed above the portion of the shaft portion 16 sealed with the seal members 12d and 12e. A projecting member 12f that curves the lower portion of the coating film 17 when open is fixed.

昇降部材１３の上部は、フッ素樹脂からなる被覆膜１７で覆われている。被覆膜１７は筒状の上端開口が塞がれた袋状に形成されていて、開閉部１５の全体および軸部１６の上部を覆い、被覆膜１７の下端１７ａの周縁部が、鉛直孔１１ａの下端開口部（１１ｆ）を囲む枠体１１の周縁部１１ｄと、その下端開口部（１１ｆ）に嵌合する前記環状固定部１２ｃとの間に挟持されている。つまり、被覆膜１７は、開閉部１５と枠体１１の周縁部１１ｄとに亘って設けられる。よって、鉛直孔１１ａの上側開口部１１ｅは、排出口３に繋がる入口を構成し、排出孔１１ｃの外側面の開口部１１ｇは出口を構成する。したがって、ホッパー本体２内の貯留物は、排出口３と上記鉛直孔１１ａと排出孔１１ｃと排出管１８と前記別の配管とを経て外部に排出可能となっている。また、このような貯留物Ａの排出通路と、昇降部材１３、軸受部１２および駆動手段１４とが、被覆膜１７により区分される。これに伴い、昇降部材１３および軸受部１２に貯留物Ａが付着せずに残らないようにすることができる。   The upper part of the elevating member 13 is covered with a coating film 17 made of a fluororesin. The coating film 17 is formed in a bag shape in which the cylindrical upper end opening is closed, covers the entire opening / closing part 15 and the upper part of the shaft part 16, and the peripheral part of the lower end 17 a of the coating film 17 is vertical. It is sandwiched between the peripheral edge portion 11d of the frame 11 surrounding the lower end opening (11f) of the hole 11a and the annular fixing portion 12c fitted into the lower end opening (11f). That is, the coating film 17 is provided across the opening / closing part 15 and the peripheral part 11 d of the frame body 11. Therefore, the upper opening 11e of the vertical hole 11a constitutes an inlet connected to the outlet 3, and the opening 11g on the outer surface of the outlet 11c constitutes an outlet. Therefore, the stored matter in the hopper body 2 can be discharged to the outside through the discharge port 3, the vertical hole 11a, the discharge hole 11c, the discharge pipe 18, and the other pipe. Further, the discharge passage of the stored material A, the elevating member 13, the bearing portion 12, and the driving means 14 are divided by the coating film 17. Accordingly, it is possible to prevent the storage material A from adhering to the elevating member 13 and the bearing portion 12 without remaining.

また、枠体１１の周縁部１１ｄと環状固定部１２ｃとの間で下端１７ａが挟持された被覆膜１７は、その下端１７ａから軸部１６に寄った部分が、排出孔１１ｃの下側の内壁Ｃと同一高さか、或いは少し上側に位置するようになっていて、貯留物を排出するときに淀みが発生しないように構成されている。   Further, the coating film 17 in which the lower end 17a is sandwiched between the peripheral edge portion 11d of the frame 11 and the annular fixing portion 12c has a portion near the shaft portion 16 from the lower end 17a on the lower side of the discharge hole 11c. The inner wall C is at the same height as or slightly above the inner wall C, and is configured so that no stagnation occurs when the stored matter is discharged.

駆動手段１４は、軸受部１２の下端周囲に上縁部２０ａが連結された筒体２０と、筒体２０の内側途中部分に上下スライド可能に設けた駆動部材２１と、筒体２０の下端に取付けた固定部材２２と、駆動部材２１と固定部材２２との間に設けた圧縮状態の開弁用のばね２３とを有する。   The driving means 14 includes a cylindrical body 20 having an upper edge portion 20 a connected to the periphery of the lower end of the bearing portion 12, a driving member 21 slidably provided in the middle part of the cylindrical body 20, and a lower end of the cylindrical body 20. The fixing member 22 is attached, and a spring 23 for opening the valve in a compressed state is provided between the driving member 21 and the fixing member 22.

駆動部材２１は軸心方向に挿通固定孔２１ａを有し、その挿通固定孔２１ａに軸部１６を挿通させた状態で軸部１６と連結されており、軸部１６と一体的に昇降する。駆動部材２１の外周面には、筒体２０の内面に接するＯリング２１ｂが設けられており、この駆動部材２１と軸受部１２と筒体２０とで囲まれた部分Ｂは気密状態となっていて、筒体２０の上部に設けたエア給排部材２４を介してエアの給排が行われる。   The drive member 21 has an insertion fixing hole 21a in the axial direction, and is connected to the shaft part 16 with the shaft part 16 inserted through the insertion fixing hole 21a, and moves up and down integrally with the shaft part 16. An O-ring 21b that is in contact with the inner surface of the cylindrical body 20 is provided on the outer peripheral surface of the driving member 21, and a portion B surrounded by the driving member 21, the bearing portion 12, and the cylindrical body 20 is in an airtight state. Thus, air is supplied / discharged via an air supply / discharge member 24 provided on the upper portion of the cylindrical body 20.

上記エア給排部材２４を介してエアを外部から前記部分Ｂに供給し、ばね２３の押圧力に抗して駆動部材２１を降下させると、この駆動部材２１に連結された軸部１６及び開閉部１５が一緒に降下して、開閉部１５が排出口３を塞ぐことにより排出口３を閉にする。一方、エア給排部材２４を介して前記部分Ｂ内のエアを外部へ放出すると、ばね２３の押圧力により駆動部材２１が上昇して、開閉部１５が上昇することにより排出口３を開にする。この排出口３が開のとき、被覆膜１７は開閉部１５に繋がる部分から枠体１１の前記周縁部１１ｄに固定された下端１７ａまでが上側から下側へ向けて連続して下側寄りに位置するように構成されている。つまり、被覆膜１７の上部である開閉部１５から軸部１６の上端部（排出口３の近傍部分）までが、上側から下側に向けて連続して下側寄りに位置し、一方の被覆膜１７の下部が、貯留物Ａの排出時に、突状部材１２ｆにより上方かつ外方へ向けて押されて、上側から下側に向けて連続して下側寄りに位置するように湾曲し、更に被覆膜１７の上部と下部との間の中間部が軸部１６に沿って同一径となっている。   When air is supplied to the portion B from the outside via the air supply / discharge member 24 and the drive member 21 is lowered against the pressing force of the spring 23, the shaft portion 16 connected to the drive member 21 and the open / close state are opened. The part 15 descends together, and the opening / closing part 15 closes the discharge port 3 to close the discharge port 3. On the other hand, when the air in the portion B is released to the outside through the air supply / discharge member 24, the drive member 21 is raised by the pressing force of the spring 23, and the opening / closing part 15 is raised to open the discharge port 3. To do. When the discharge port 3 is open, the coating film 17 is continuously shifted from the upper side to the lower side from the part connected to the opening / closing part 15 to the lower end 17a fixed to the peripheral edge part 11d of the frame body 11 toward the lower side. It is comprised so that it may be located in. That is, the opening / closing part 15 that is the upper part of the coating film 17 and the upper end part of the shaft part 16 (the vicinity of the discharge port 3) are continuously located closer to the lower side from the upper side to the lower side, The lower portion of the coating film 17 is pushed upward and outward by the projecting member 12f when the storage A is discharged, and is curved so as to be continuously located on the lower side from the upper side to the lower side. Further, an intermediate portion between the upper portion and the lower portion of the coating film 17 has the same diameter along the shaft portion 16.

このように構成された本実施形態に係るホッパー１にあっては、ホッパー本体２の下端部２ａに排出装置１０が取付けられてホッパー本体２と排出装置１０が一体化されており、しかも排出口３を開閉する開閉部１５を有する昇降部材１３の軸部１６が軸受部１２により昇降可能に支持されているので、開閉部１５の近傍において従来必要としていた互いに摺動する機構の案内手段を省略することが可能となり、これに伴って案内手段に付着して貯留物Ａが残ることを防止することができ、これにより貯留物Ａが混じることを防ぐことが可能になる。   In the hopper 1 according to the present embodiment configured as described above, the discharge device 10 is attached to the lower end portion 2a of the hopper body 2, the hopper body 2 and the discharge device 10 are integrated, and the discharge port Since the shaft portion 16 of the elevating member 13 having the opening / closing portion 15 that opens and closes 3 is supported by the bearing portion 12 so as to be able to move up and down, the guide means of the sliding mechanism required conventionally in the vicinity of the opening / closing portion 15 is omitted. As a result, it is possible to prevent the storage A from adhering to the guiding means and to prevent the storage A from being mixed.

加えて、本実施形態にあっては、ホッパー本体２の下端部２ａに取付けられた排出装置１０が排出口３及び枠体１１の鉛直孔１１ａの内側を昇降可能な昇降部材１３を備え、その昇降部材１３における開閉部１５と、その下側の鉛直孔１１ａの下端開口部を囲む枠体１１の周縁部１１ｄとに亘って被覆膜１７が設けられており、また軸受部１２が枠体１１よりも下側に配設されているので、昇降部材１３及び軸受部１２と、貯留物Ａを排出する通路とを被覆膜１７により区分することができる。よって、昇降部材１３及び軸受部１２に貯留物Ａが付着せずに残らないようにすることができる。更に、被覆膜１７が低摩擦性のフッ素樹脂からなるため、被覆膜１７自身にも貯留物Ａの付着が起こらない。その結果、このことによっても貯留物Ａが混じることを防止することが可能となる。更に、開閉部１５が排出口３よりも上側に位置する構成であるので、仮に貯留物Ａが前述した棚吊りになっていても、昇降部材１３を駆動手段１４により昇降させて、その棚吊りとなっている貯留物Ａの部分を上方に押し上げることにより、棚吊りを崩すことができる。   In addition, in this embodiment, the discharge device 10 attached to the lower end 2a of the hopper body 2 includes a lifting member 13 that can move up and down the discharge port 3 and the vertical hole 11a of the frame 11, A covering film 17 is provided over the opening / closing portion 15 of the elevating member 13 and the peripheral edge portion 11d of the frame body 11 surrounding the lower end opening of the vertical hole 11a below it, and the bearing portion 12 is a frame body. 11, the elevating member 13 and the bearing portion 12 and the passage for discharging the stored material A can be divided by the coating film 17. Therefore, it is possible to prevent the storage material A from adhering to the elevating member 13 and the bearing portion 12 without remaining. Furthermore, since the coating film 17 is made of a low-friction fluororesin, the deposit A does not adhere to the coating film 17 itself. As a result, this also makes it possible to prevent the stored material A from being mixed. Further, since the opening / closing portion 15 is positioned above the discharge port 3, even if the storage A is the above-described shelf hanging, the lifting member 13 is lifted and lowered by the driving means 14, and the shelf hanging is performed. The shelf suspension can be broken by pushing up the portion of the storage A that is formed upward.

また、本実施形態にあっては、上述した開閉部１５の上昇に伴って排出口３が開状態となって、ホッパー本体２の内部の貯留物Ａを外部へ排出することができる。この排出時において、上述したように被覆膜１７における開閉部１５に繋がる部分から枠体１１の底面に固定された下端１７ａまでが上側から下側へ向けて連続して下側寄りに位置することに加えて、上述したように被覆膜１７の下端１７ａから軸部１６に寄った部分が排出孔１１ｃの下側の内壁Ｃと同一高さか、或いは少し上側に位置する。よって、貯留物が溜まり易い淀み箇所が無くなり、貯留物が残るのを確実に防止することが可能になる。更に、排出管１８が斜め下向きに延びているので、貯留物を排出孔１１ｃから残すことなく排出管１８を介して外部へ排出することができる。   Moreover, in this embodiment, the discharge port 3 will be in an open state with the raise of the opening-and-closing part 15 mentioned above, and the stored matter A inside the hopper main body 2 can be discharged | emitted outside. At the time of discharging, as described above, the portion of the coating film 17 connected to the opening / closing portion 15 to the lower end 17a fixed to the bottom surface of the frame body 11 is continuously located on the lower side from the upper side to the lower side. In addition, as described above, the portion of the coating film 17 that is closer to the shaft portion 16 from the lower end 17a is located at the same height as or slightly above the lower inner wall C of the discharge hole 11c. Therefore, there is no stagnation part where the stored material is likely to be stored, and it is possible to reliably prevent the stored product from remaining. Furthermore, since the discharge pipe 18 extends obliquely downward, the stored matter can be discharged to the outside through the discharge pipe 18 without leaving the discharge hole 11c.

なお、上述した実施形態では開閉部１５の上側部分が被覆膜１７で覆われた状態に構成しているが、本発明はこれに限らない。例えば、図２または図３に示す構成としてもよい。なお、図２、図３においても図１と同様に右半分は排出口が閉の状態を示し、左半分は排出口が開の状態を示す。また図２及び図３においては、図１と同一部分には同一符号を付している。   In the above-described embodiment, the upper part of the opening / closing part 15 is configured to be covered with the coating film 17, but the present invention is not limited to this.
