［産業上の利用分野コ
本発明は、例えば耐火煉瓦を成形する粉末成形機の原料
供給装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a raw material supply device for a powder molding machine for molding firebricks, for example.
［従来の技術］
従来のかかる装置は第７図に示すように、テーブル２上

のキャビティ１ａ内に投入していた。なお、図面の記号
Ｂは金型１の上下動により金型１に対し相対的に昇降す
る下部ラムである。[Prior Art] As shown in FIG. 7, such a conventional device includes a charger 6 with a vertical opening that can freely slide on a table 2, and a weighing device 8.
The raw material A is supplied through the supply port 4a of the charger cover 4, and as shown in FIG.
a, move the charger 6 to a position facing the mold 1, and feed the raw material A into the mold 1 through the opening 2a of the table 2.
It was put into the cavity 1a. Note that the symbol B in the drawing is a lower ram that moves up and down relative to the mold 1 as the mold 1 moves up and down.
［発明か解決しようとする課題］
上記の従来装置は、投入時の原料の落差か比較的小さく
、したかって、粉末原料Ａの分離か少なく有効である。[Problems to be Solved by the Invention] The above-mentioned conventional apparatus has a relatively small drop in the raw material at the time of charging, and is therefore effective in that the powder raw material A is separated with a small amount.
しかし、原料Ａか、例えばマグネシャ、アルミナ、ジル
コン、コランダム等の硬度の大きい粗粒か配合されてい
る場合は、柔らかい粘度と異なってチャージャ６の下部
開口の原料Ａと接するテーブル２の上面をチャージャ６
か往復動する際、テーブル２の上面及びチャージャ６の
下面の摩耗か大きく、両者の交換回数か多くなる。However, if the raw material A is mixed with coarse grains with high hardness such as magnesia, alumina, zircon, or corundum, the upper surface of the table 2 in contact with the raw material A at the lower opening of the charger 6 is different from the soft viscosity. 6
During the reciprocating movement, the upper surface of the table 2 and the lower surface of the charger 6 become more abrasive, increasing the number of times they must be replaced.
また、前記のテーブル２の上面及びチャージャ６の底面
の摩耗により移動の度にかなりの原料Ａのこぼれがあり
、これが摩耗を助長する。このことは、近時、煉瓦の形
状が大型化し、１個５０ｋｇ以上のものの原料となると
、チャージャ６の移動ストロークが大きくなることで、
益々助長される。Furthermore, due to wear on the top surface of the table 2 and the bottom surface of the charger 6, a considerable amount of the raw material A spills every time it is moved, which accelerates the wear. This means that in recent years, bricks have become larger in size, and as they become raw materials for items weighing more than 50 kg each, the movement stroke of the charger 6 becomes larger.
It is encouraged more and more.
また、成形した煉瓦の寸法交差及びかさ密度の交差も年
々厳しくなり、計量した原料を投入しても、こぼれが大
きいと投入量が不正確になる。In addition, the dimensional tolerances and bulk density tolerances of molded bricks are becoming stricter year by year, and even if a measured amount of raw material is input, if there is a large spillage, the amount of input will be inaccurate.
また、生産性を向上するためには、チャージャ６の移動
速度を大きくする必要かあるが、これも例えば水を充満
した上方開口の容器を前後に早い速度で移動するのと同
様に、原料Ａの表面の踊り現象により、移動速度が制約
される。In addition, in order to improve productivity, it is necessary to increase the moving speed of the charger 6, but this is also the same as moving a top-opening container filled with water back and forth at a high speed. The movement speed is limited by the surface dancing phenomenon.

問題がある。On the other hand, the present applicant, in Japanese Patent Application No. 1-205639,
Although a downward-opening raw material supply device has been proposed, there is a problem in that the shutter opens and closes incompletely due to the raw material adhering to the shutter.
本発明は、チャージャに投入された原料の摺接面へのこ
ぼれをなくすと共に、チャージャの移動速度を増大する
粉末成形機の原料供給装置を提供することを目的として
いる。SUMMARY OF THE INVENTION An object of the present invention is to provide a raw material supply device for a powder molding machine that eliminates spillage of raw materials fed into a charger onto a sliding surface and increases the moving speed of the charger.

ジャを往復移動させる第２のシリンダとを設けている。[Means for Solving the Problems] According to the present invention, a charger holder that is slidable on a table and has an input port formed on the mold side, a first cylinder that reciprocates the charger holder, and a first cylinder that moves the charger holder back and forth; The charger is provided with a charger that is slidable on the charger holder and has a vertical opening, and a second cylinder that is interposed between the charger and the charger holder and moves the charger back and forth.
前記第１のシリンダは、ストローク及び作動速度の大き
い油圧又は空圧シリンダで構成するのか好ましい。Preferably, the first cylinder is a hydraulic or pneumatic cylinder with a large stroke and operating speed.
また、第２のシリンダは、チャージャの金型側側部とチ

リンダで構成するのが好ましい。Further, it is preferable that the second cylinder is constituted by a pair of hydraulic or pneumatic cylinders interposed between the mold side side portion of the charger and the charger holder.
［作用］
上記のように構成された粉末成形機の原料供給装置にお
いては、第１、第２のシリンダを収縮したチャージャの
原位置において、秤量機で計量した原料をチャージャに
投入する。[Operation] In the raw material supply device for the powder molding machine configured as described above, the raw material weighed by the weighing machine is charged into the charger at the original position of the charger with the first and second cylinders contracted.
次いて、第１のシリンダを伸長し、チャージャホルタを
その投入口が金型に対向する位置まで移動する。Next, the first cylinder is extended and the charger holter is moved to a position where its input port faces the mold.
次いて、第２のシリンダを伸長し、チャージャを投入口
に移動し、チャージャ内の原料を投入口から金型のキャ
ビテーションに投入する。Next, the second cylinder is extended, the charger is moved to the inlet, and the raw material in the charger is injected from the inlet into the cavitation of the mold.
次いて、第１、第２のシリンダを収縮し、チャ／子を原
位置に復帰し、以降、前記と同様の動作を繰り返し、原
料を金型に投入する。Next, the first and second cylinders are contracted, the chamber is returned to its original position, and the same operations as described above are repeated to charge the raw material into the mold.

ブル上には落下しないので、テブル上面か原料により摩
耗することかない。そのために、チャージャを高速度で
移動させても不都合か生ぜず、したかって、作業時間を
短縮化し、効率を向上させることかできる。When moving the charger, even if the charger is moved quickly, the raw material will fall onto the charger holder and will not fall onto the table, so the upper surface of the table will not be abraded by the raw material. Therefore, even if the charger is moved at a high speed, there is no inconvenience, and therefore the working time can be shortened and efficiency can be improved.
また、チャージャホルタのストロークは比較的長いので
、チャージャホルダは高速で動かし、チャージャのスト
ロークは比較的に短いので、チャーシャは低速で動かす
ことかできる。なお後退時は高速移動させるのが好まし
い。Further, since the stroke of the charger holder is relatively long, the charger holder can be moved at high speed, and since the stroke of the charger is relatively short, the charger can be moved at low speed. Note that it is preferable to move at high speed when reversing.
