Abstract
Description
本発明は、ダマ砕き装置に関する。より詳しくは、本発明は、鋳造工場において、混練機あるいは混砂機で調整した調整砂をベルトコンベアなどの搬送装置で搬送し、生砂造型機の上部の砂受入口へ投入する際に、調整砂に含まれるダマを砕く装置に関する。 The present invention relates to a dama crusher. More specifically, the present invention, in a foundry, transports adjusted sand adjusted by a kneading machine or a mixed sand machine by a conveyor device such as a belt conveyor, and puts it into the sand receiving port at the top of the green sand molding machine. The present invention relates to an apparatus for crushing lumps contained in adjustment sand.
従来、鋳造工場において、鋳型造型に用いる生砂を調整した調整砂には、混練の際に圧力が加えられ、砂粒同士が粘着して、ダマが発生・混在する。この混練砂のダマを砕き、より良い造型用の砂にするため、ダマ砕き装置は公知である（例えば、特許文献１）。 Conventionally, in a foundry, adjusted sand prepared from mold sand used for mold making is subjected to pressure during kneading, causing sand particles to adhere to each other, resulting in generation and mixing of lumps. In order to break the kneaded sand lump into better molding sand, a lump crusher is known (for example, Patent Document 1).
特許文献１に記載されたダマ砕き装置は、垂直に植設した多数の内側ピンと多数の外側ピンが同心円状に配置され、内側のピンを回転させ外側の固定ピンとの隙間で生型砂のダマを砕いている。このダマ砕き装置は、造型用の砂の調整には非常に有効である。
しかしながら、このダマ砕き装置は装置の高さと設置のための高さが必要であり、この装置の導入には、生砂造型機の上方に配置されている既設ベルトコンベヤを１メートルほど嵩上げが必要となる場合があった。そのため、建屋まで改造が必要となり、ダマ砕き装置の導入を断念するケースがあった。更に、改造は不要な場合であっても作業スペース、メンテナンススペースの確保に難があった。
一方、造型機としてエアレーション式などの空気を用いる場合においては、空気流により調整砂を鋳型空間、特に狭いポケット等の鋳型空間に均一に充填することができるが、その造型性能を向上・維持するためには、ダマのない調整砂を造型機に供給することがより好ましいので、ダマ砕き装置は重要性を増している。
In the dama crusher described in Patent Document 1, a large number of vertically arranged inner pins and a large number of outer pins are arranged concentrically. It is crushed. This dama crusher is very effective in adjusting sand for molding.
However, this dama crushing device requires a height of the device and a height for installation. To introduce this device, the existing belt conveyor arranged above the green sand molding machine needs to be raised by about 1 meter. There was a case. Therefore, it was necessary to remodel the building, and there was a case where the introduction of the crusher was abandoned. Furthermore, even if no modification is required, it is difficult to secure a working space and a maintenance space.
On the other hand, when aeration type air is used as the molding machine, the adjustment sand can be uniformly filled into the mold space, particularly a mold space such as a narrow pocket, by the air flow, but the molding performance is improved and maintained. In order to do this, it is more preferable to supply conditioned sand without lumps to the molding machine, so the lumps crushers are gaining in importance.
そこで、上述の事情に鑑み、本発明は、設備装置の高さ及び設備装置を設置するための高さが低く、かつ、エアレーション式などの空気を用いた造型機の性能を引き出すダマ砕き装置を提供することを目的とする。 Therefore, in view of the above-described circumstances, the present invention provides a dama crusher that draws out the performance of a molding machine using air such as an aeration type that is low in height and the height for installing the equipment. The purpose is to provide.
本発明のダマ砕き装置は、両端部が支持される砕き棒であって回転軸の半径方向に等間隔に延設された複数の羽根を有する第１砕き棒と、該砕き棒と水平面上で平行に間隔をおいて支持されると共に第１砕き棒とは反対方向に回転する回転軸を有する第２砕き棒とを備え、前記第１砕き棒と第２砕き棒との間に調整砂を上方から供給すると該調整砂を上から下に向かって梳ってダマを砕くダマ砕き装置において、前記第１砕き棒と前記第２砕き棒はそれぞれの端部に設けられた歯車により連結され、一つのモーターにより一方の砕き棒を回転させることにより、他方の砕き棒も回転させることを特徴とする。 The dama crusher of the present invention is a crushing rod that is supported at both ends, and includes a first crushing rod having a plurality of blades extending at equal intervals in the radial direction of the rotating shaft, and the crushing rod and the horizontal surface. A second crushing rod supported in parallel and spaced apart and having a rotating shaft rotating in a direction opposite to the first crushing rod, and adjusting sand is provided between the first crushing rod and the second crushing rod. In a dama crushing device that crushes the adjustment sand from above by crushing the adjustment sand from above, the first crushing rod and the second crushing rod are connected by gears provided at respective end portions, By rotating one crushing bar with one motor, the other crushing bar is also rotated.
本発明によれば、設備高さ及び設置の高さを低くして設備投資コスト削減ができ、かつ、エアレーション式などの造型機の性能を引き出すことができるなどの効果を奏する。またモーターが一つで済むため、設備投資コストをさらに削減することができる。 According to the present invention, it is possible to reduce the equipment investment cost by reducing the equipment height and installation height, and to bring out the effects of being able to draw out the performance of an aeration type molding machine. Moreover, since only one motor is required, the capital investment cost can be further reduced.
以下、添付図面に基づいて本発明の一実施の形態にかかわるダマ砕き装置を説明する。図１は、本発明のダマ砕き装置を示す概略図である。本発明のダマ砕き装置１は、第１砕き棒Ｂ１と、この砕き棒Ｂ１と水平面上で平行に間隔をおいて支持されると共に第１砕き棒Ｂ１とは反対方向に回転する回転軸３を有する第２砕き棒Ｂ２と、を具備している。 Hereinafter, a lump crushing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view showing a dama crusher according to the present invention. The lump crushing apparatus 1 of the present invention includes a first crushing bar B1 and a rotating shaft 3 that is supported in parallel with the crushing bar B1 on a horizontal plane and rotates in a direction opposite to the first crushing bar B1. And having a second crushing bar B2.
そして、各砕き棒Ｂ１、Ｂ２は、両端部が、例えば、シュートＳｈの最上部に両側を支持されている。また、各砕き棒Ｂ１、Ｂ２は、回転軸３、３の半径方向に等間隔に延設された複数の羽根２、２を有している。ここで、シュートＳｈは、上部から下部に向けて巾が狭くなっており、その最下部は、造型機の上部のサンドタンクに連通可能になっている。ただし、シュートは、調整砂が外にこぼれない構造であれば、その構造は問わない。なお、羽根２は、板材の切り出し、丸棒、６角ボルトの植え込み、など様々なバリエーションが可能である。 And as for each crushing rod B1, B2, both ends are supported by the uppermost part of chute | shoot Sh, for example. Moreover, each crushing bar B1 and B2 has the some blade | wings 2 and 2 extended in the radial direction of the rotating shafts 3 and 3 at equal intervals. Here, the width | variety of chute Sh is narrowed toward the lower part from the upper part, The lowermost part can be connected with the sand tank of the upper part of a molding machine. However, the structure of the chute is not limited as long as the adjustment sand does not spill outside. In addition, the blade | wing 2 can be variously varied, such as cutting out a plate material, implanting a round bar, and a hexagonal bolt.
また、図１に示すように、ダマ砕き装置１は、第１砕き棒Ｂ１の羽根２、２の間の間隙４に、前記第２砕き棒Ｂ２の羽根２が入り込み、調整砂Ｓを上から下に向かって梳ってダマ砕きするように構成されている。この構成により、調整砂を、梳り、或いは、せん断・切断作用により効率的に砕くことができる。 Further, as shown in FIG. 1, the dama crusher 1 is configured such that the blade 2 of the second crushing rod B2 enters the gap 4 between the blades 2 and 2 of the first crushing rod B1, and the adjustment sand S is introduced from above. It is configured to crush down and crush it. With this configuration, the adjustment sand can be efficiently crushed by grinding or shearing / cutting action.
図１，２に示すように、第１砕き棒Ｂ１と第２砕き棒Ｂ２とは、それぞれの端部に設けられた歯車６により連結されている。ここで、第１砕き棒Ｂ１の回転軸３は、ローラーチェーン７によりモーター５に連結されている。これにより、モーター５を駆動させることにより、第１砕き棒Ｂ１を回転させ、同時に、第２砕き棒Ｂ２を、第１砕き棒Ｂ１とは反対方向に回転させることができる。 As shown in FIGS. 1 and 2, the first crushing bar B <b> 1 and the second crushing bar B <b> 2 are connected to each other by a gear 6 provided at each end. Here, the rotating shaft 3 of the first crushing bar B <b> 1 is connected to the motor 5 by the roller chain 7. Thereby, by driving the motor 5, the first crushing bar B1 can be rotated, and at the same time, the second crushing bar B2 can be rotated in the direction opposite to the first crushing bar B1.
以下、本装置の作動について説明する。図４に示すように、調整砂投入装置８より、ダマ砕き装置１の上方から調整砂を投入する。そして、モーター５を駆動させることにより、ローラーチェーン７を介して第１砕き棒Ｂ１を回転させる。これにより、第１砕き棒Ｂ１および第２砕き棒Ｂ２の端部に設けられた歯車６，６を介して、第２砕き棒Ｂ２を回転させる。 Hereinafter, the operation of the present apparatus will be described.

Then, by driving the motor 5, the first crushing bar B <b> 1 is rotated via the roller chain 7. Thereby, the 2nd crushing bar B2 is rotated via the gearwheels 6 and 6 provided in the edge part of 1st crushing bar B1 and 2nd crushing bar B2.
このとき、第１砕き棒Ｂ１および第２砕き棒Ｂ２の回転方向は、図３に示すように、第１砕き棒Ｂ１が反時計回り、第２砕き棒Ｂ２が時計回りである。これにより、上方から投入される調整砂を上から下に向かって梳ることができる。 At this time, as shown in FIG. 3, the rotation direction of the first crushing bar B1 and the second crushing bar B2 is that the first crushing bar B1 is counterclockwise and the second crushing bar B2 is clockwise. Thereby, the adjustment sand thrown in from the upper direction can be rolled up from the top to the bottom.
以上のように、本発明のダマ砕き装置１は、設備高さ及び設置の高さを低くして設備投資コスト削減ができ、かつ、エアレーション式などの造型機の性能を引き出すことができるなどの効果を奏する。また、モーターが一つで良いため、設備投資コストをさらに削減することができる。 As described above, the lump crusher 1 of the present invention can reduce the equipment investment cost by reducing the height of the equipment and the height of the installation, and can draw out the performance of the molding machine such as the aeration type. There is an effect. Moreover, since only one motor is required, the capital investment cost can be further reduced.
以上、本発明による代表的実施例について説明したが、本発明は必ずしもこれに限定されるものではなく、当業者であれば、添付した特許請求の範囲を逸脱することなく、種々の代替実施例及び改変例を見出すことは可能である。 While typical embodiments of the present invention have been described above, the present invention is not necessarily limited thereto, and various alternative embodiments can be made by those skilled in the art without departing from the scope of the appended claims.
