Description

本発明は、鋳物の連続生産ラインに用いられるシェイクアウトマシンとその運転方法に関するものである。 The present invention relates to a shakeout machine used in a continuous production line for castings and a method of operating the same.

鋳物の連続生産ラインにおいては、鋳型を破砕して鋳物と砂とを分離し、砂を回収するとともに鋳物を取り出すために、特許文献１に示されるようなシェイクアウトマシンが用いられている。図５ａ、図５ｂに示すように、従来のシェイクアウトマシン２０１は、振動トラフ２０７をコイルばね、空気ばね、ゴムばね、板ばね等の弾性体２１１によりフローティング状態に支持し、その幅方向の両側に２台の振動モータ２１０を並列に取付けた構造となっている。 In a continuous production line for castings, a shakeout machine as shown in Patent Document 1 is used to crush a mold to separate castings and sand, collect sand, and take out castings. As shown in FIGS. 5a and 5b, in the conventional shakeout machine 201, the vibration trough 207 is supported in a floating state by elastic bodies 211 such as coil springs, air springs, rubber springs, and leaf springs, and both sides in the width direction thereof. The structure is such that two vibration motors 210 are mounted in parallel.

これらの２台の振動モータ２１０を互いに反対方向に回転させることにより、それぞれの振動モータ２１０の加振力が互いに反対方向に作用して相殺され、２台の振動モータ２１０の加振力の方向が揃う方向、すなわちモータ回転軸、及び２台の振動モータ２１０をつなぐ線と直角方向の加振力のみが振動トラフ２０７に作用する。その様子を図６に示す。 By rotating these two vibration motors 210 in opposite directions, the exciting forces of the respective vibration motors 210 act in opposite directions to cancel each other out, and the directions of the exciting forces of the two vibration motors 210. Only the exciting force in the direction in which they are aligned, that is, in the direction perpendicular to the line connecting the motor rotation shaft and the two vibration motors 210, acts on the vibration trough 207. The situation is shown in FIG.

シェイクアウトマシンにおいては、２台の振動モータ２１０の配置により決定される振動方向を斜め上方に打ち上げる方向とし、振動トラフ２０７の長手方向であるＸ方向の分力を素材搬送力として用い、上下方向であるＹ方向の分力を砂鋳型破砕力として用いている。振動トラフ２０７をコイルばね、空気ばね、ゴムばね、板ばね等の弾性体２１１によりフローティング状態に支持した場合には、図６に示すように振動モータ２１０の加振力の作用点を振動トラフ２０７の重心と一致させる必要がある。その場合にのみ振動トラフの姿勢が揺動することなく、平行移動で振動させることができる。もし振動モータ２１０の加振力の作用点を振動トラフ２０７の重心と一致していない場合には、図７、図８に示すように振動トラフ２０７に回転力が発生する。 In the shakeout machine, the vibration direction determined by the arrangement of the two vibration motors 210 is set to launch diagonally upward, and the component force in the X direction, which is the longitudinal direction of the vibration trough 207, is used as the material transport force in the vertical direction. The component force in the Y direction is used as the sand mold crushing force. When the vibration trough 207 is supported in a floating state by an elastic body 211 such as a coil spring, an air spring, a rubber spring, or a leaf spring, the vibration trough 207 is the point of action of the exciting force of the vibration motor 210 as shown in FIG. It is necessary to match the center of gravity of. Only in that case, the posture of the vibration trough can be vibrated by translation without swinging. If the point of action of the exciting force of the vibration motor 210 does not coincide with the center of gravity of the vibration trough 207, a rotational force is generated in the vibration trough 207 as shown in FIGS. 7 and 8.

図７では加振力の作用点よりも振動トラフ２０７の重心が図面上の左側にあるため、振動トラフ２０７がシーソーの様な挙動で振動し、Ｘ方向の分力（素材搬送力）とＹ方向の分力（砂鋳型破砕力）とが振動トラフ２０７の各位置で変化する。そして振動トラフ２０７の出口側（右側）では搬送物の打ち上げ方向が逆になり、搬送不能となる。図８は加振力の作用点よりも振動トラフ２０７の重心が図面上の右側にある状態を示しており、やはり図７の場合と同様の問題を生じる。これらは振動トラフ２０７が長く、搬送物の投入量の変動、搬送物の偏積、付着、引っ掛かりがあるような場合に発生し易い。その結果、搬送不能となるリスクがある。 In FIG. 7, since the center of gravity of the vibrating trough 207 is on the left side of the drawing from the point of action of the exciting force, the vibrating trough 207 vibrates like a seesaw, and the component force (material transport force) in the X direction and Y The directional component force (sand mold crushing force) changes at each position of the vibrating trough 207. Then, on the outlet side (right side) of the vibrating trough 207, the launch direction of the transported object is reversed, and the transported object cannot be transported. FIG. 8 shows a state in which the center of gravity of the vibration trough 207 is on the right side of the drawing with respect to the point of action of the exciting force, which also causes the same problem as in the case of FIG. 7. These are likely to occur when the vibration trough 207 is long and there are fluctuations in the input amount of the transported object, uneven accumulation of the transported object, adhesion, and catching. As a result, there is a risk that it cannot be transported.

このような振動トラフの揺動を防止するために、振動トラフを平行リンクにより支持し、偏芯軸を回転させて振動方向を決めることも考えられる。しかし構造が複雑となり高加振力に耐えられないため、砂鋳型の破砕と素材の分離を目的とするシェイクアウトマシンに応用することはできない。 In order to prevent such vibration of the vibration trough, it is conceivable to support the vibration trough with a parallel link and rotate the eccentric shaft to determine the vibration direction. However, since the structure is complicated and cannot withstand high excitation force, it cannot be applied to a shakeout machine for the purpose of crushing a sand mold and separating materials.

従って本発明の目的は上記した従来の問題点を解決し、構造が簡単、かつ強度を確保できる振動モータにて加振する構造でありながら、長尺トラフを用いても搬送物の投入量の変動、搬送物の偏積、付着、引っ掛かり等の影響にて、揺動や搬送不能を発生させることのないシェイクアウトマシンとその運転方法を提供することである。 Therefore, an object of the present invention is to solve the above-mentioned conventional problems, and although the structure is simple and the structure is vibrated by a vibration motor that can secure the strength, even if a long trough is used, the input amount of the transported object can be increased. It is an object of the present invention to provide a shakeout machine and an operation method thereof that do not cause swinging or inability to transport due to the influence of fluctuation, uneven accumulation of transported objects, adhesion, catching, etc.

Two vibration motors are attached so that a line connecting the centers of each vibration motor passes through the shaft, and these vibration motors rotate in opposite directions to cancel out vibration forces other than the rotation direction and act on the shaft.

以下に本発明の実施形態を説明する。
図１ａに、本発明のシェイクアウトマシン１を用いた鋳造ラインの後処理設備２を示す。図１ｂは図１ａのＡ−Ａ矢視図である。この後処理設備２はシェイクアウトマシン１の上流側に振動コンベア３を配置し、シェイクアウトマシン１の格子４の上部の搬出側にエプロンコンベア５を配置し、シェイクアウトマシン１の格子４の下部の搬出側にベルトコンベヤ６を配置した構成である。 An embodiment of the present invention will be described below.
FIG. 1a shows the post-treatment equipment 2 of the casting line using the shakeout machine 1 of the present invention. FIG. 1b is a view taken along the line AA of FIG. 1a. In this aftertreatment facility 2, the vibration conveyor 3 is arranged on the upstream side of the shakeout machine 1, the apron conveyor 5 is arranged on the carry-out side of the upper part of the grid 4 of the shakeout machine 1, and the lower part of the grid 4 of the shakeout machine 1 is arranged. The belt conveyor 6 is arranged on the carry-out side of the above.

第１の実施形態のシェイクアウトマシン１は、振動トラフ７の下流側である一方端に振動トラフ７をピン支持する軸８と軸受９を配置し、振動トラフ７の上流側である他方端に回転軸を水平にした１台の振動モータ１０と、コイルばね、空気ばね、ゴムばね、板ばね等の弾性体１１を配置し、振動トラフ７を支えている。軸８と軸受９を用いる代わりに、軸をボスに圧入したゴムブッシュで支持する構造としてもよい。 In the shakeout machine 1 of the first embodiment, a shaft 8 and a bearing 9 for pin-supporting the vibration trough 7 are arranged at one end on the downstream side of the vibration trough 7, and at the other end on the upstream side of the vibration trough 7. A vibration motor 10 having a horizontal rotation axis and an elastic body 11 such as a coil spring, an air spring, a rubber spring, and a leaf spring are arranged to support the vibration trough 7. Instead of using the shaft 8 and the bearing 9, the shaft may be supported by a rubber bush press-fitted into the boss.

振動モータ１０の回転により、振動トラフ７は軸８を回転中心として振動する。振動トラフ７の一方端に軸８と軸受９を配置することにより、従来構造では２台の振動モータが必要であった加振力を、本発明ではてこの原理にて１台の振動モータ１０で得ることができる。その理由は後述する。 Due to the rotation of the vibration motor 10, the vibration trough 7 vibrates around the shaft 8 as the center of rotation. By arranging the shaft 8 and the bearing 9 at one end of the vibration trough 7, the exciting force that required two vibration motors in the conventional structure can be reduced by the principle of one vibration motor 10 in the present invention. Can be obtained at. The reason will be described later.

振動コンベア３から鋳物素材を内包した砂鋳型（図示せず）がシェイクアウトマシン１上に搬送され、シェイクアウトマシン１の格子４上で打ち上げられることにより、砂鋳型が破砕され、破砕された鋳物砂は格子４の下のベルトコンベヤ６に搬出される。格子４上に残った鋳物素材は、エプロンコンベア５にて搬出される。 A sand mold (not shown) containing a casting material is conveyed from the vibrating conveyor 3 onto the shakeout machine 1 and launched on the grid 4 of the shakeout machine 1, whereby the sand mold is crushed and the crushed casting. The sand is carried out to the belt conveyor 6 under the lattice 4. The casting material remaining on the lattice 4 is carried out by the apron conveyor 5.

図３に示すように、軸８と軸受９を振動トラフ７の下流側に配置することにより、振動トラフ７の上流側の振幅を大きく、下流側の振幅を小さくすることができる。これにより搬送物の投入側の砂鋳型の破砕性を大きくすることができ、また搬送物の搬出側の素材への打痕発生を低減することができる。軸８を中心に回転運動をさせることにより、振動トラフ７が長く、搬送物の投入にピークがある場合でも、振動トラフ７が従来のようにシーソーのような挙動をすることを防止することができる。 As shown in FIG. 3, by arranging the shaft 8 and the bearing 9 on the downstream side of the vibration trough 7, the amplitude on the upstream side of the vibration trough 7 can be increased and the amplitude on the downstream side can be decreased. As a result, the crushability of the sand mold on the loading side of the transported object can be increased, and the occurrence of dents on the material on the transport side of the transported object can be reduced. By rotating around the shaft 8, it is possible to prevent the vibrating trough 7 from behaving like a seesaw as in the conventional case even when the vibrating trough 7 is long and there is a peak in the loading of the conveyed object. it can.

また図３に示すように、振動モータ１０を振動トラフ７の重心に対してオーバーハングした位置に取付けることにより、振動モータ１０の加振力の低減が図れる。すなわち、１台の振動モータ１０の加振力をＦ０とし、軸８から振動モータ１０の中心までの長さをＬとすると、発生トルクＭはＭ=Ｆ０×Ｌとなり、重心における加振力ＦはＦ=Ｍ／（Ｌ／２）＝Ｆ０×Ｌ／（Ｌ／２）＝２Ｆ０となる。 Further, as shown in FIG. 3, by mounting the vibration motor 10 at a position overhanging the center of gravity of the vibration trough 7, the exciting force of the vibration motor 10 can be reduced. That is, assuming that the exciting force of one vibration motor 10 is F 0 and the length from the shaft 8 to the center of the vibration motor 10 is L, the generated torque M is M = F 0 × L, and the vibration at the center of gravity is excited. The force F is F = M / (L / 2) = F 0 × L / (L / 2) = 2F 0 .

なお、このような構造としたことにより、振動トラフ７の上流側の振幅が大きく、下流側の振幅が小さくなるため、素材の搬送能力が下流側程小さくなる。そこで図３に示すように振動トラフ７の下流側を下げた傾斜構造として、素材の搬送能力（搬送速度）を制御することができる。このため、図２に示すように振動トラフ７を支持する軸受９の上下方向の高さを調整可能にし、軸受９の取付高さを変えることにより振動トラフ７の傾斜角度を変更して素材の搬送能力（搬送速度）を制御するようにしてもよい。 With such a structure, the amplitude on the upstream side of the vibration trough 7 is large and the amplitude on the downstream side is small, so that the material transporting capacity is reduced toward the downstream side. Therefore, as shown in FIG. 3, the material transfer capacity (transport speed) can be controlled by using an inclined structure in which the downstream side of the vibration trough 7 is lowered. Therefore, as shown in FIG. 2, the height of the bearing 9 supporting the vibration trough 7 in the vertical direction can be adjusted, and the inclination angle of the vibration trough 7 can be changed by changing the mounting height of the bearing 9 to make the material. The transport capacity (transport speed) may be controlled.

図４に示す第２の実施形態は請求項２に対応するもので、２台の振動モータ３１０を使用した例である。振動トラフ３０７の一方端を一箇所の軸３０８と軸受３０９で支持し、振動トラフ３０７の他方端をコイルばね、空気ばね、ゴムばね、板ばね等の弾性体３１１で支える構造とし、互いに逆回転する２台の振動モータ３１０を各振動モータの中心を結ぶ線Ａが軸３０８を通るように取付ける。この構造により振動トラフ３０７の回転方向以外の振動力を相殺する取り合いとし、軸３０８と軸受３０９への振動モータ３１０の反力を低減する。 The second embodiment shown in FIG. 4 corresponds to claim 2, and is an example in which two vibration motors 310 are used. One end of the vibration trough 307 is supported by one shaft 308 and a bearing 309, and the other end of the vibration trough 307 is supported by an elastic body 311 such as a coil spring, an air spring, a rubber spring, or a leaf spring. The two vibration motors 310 are attached so that the line A connecting the centers of the vibration motors passes through the shaft 308. With this structure, the vibration force other than the rotation direction of the vibration trough 307 is offset, and the reaction force of the vibration motor 310 to the shaft 308 and the bearing 309 is reduced.

この場合、１台の振動モータ３１０の加振力は第１の実施形態の振動モータ１０の１／２でよい。 In this case, the exciting force of one vibration motor 310 may be 1/2 of that of the vibration motor 10 of the first embodiment.

以上に説明した本発明の効果を要約すると、次の通りである。
１、構造が単純なため、強度アップが容易。
２、構造が単純なため、安価。
３、振動トラフの一方端を軸で支持する事により、てこの原理にて２台の振動モータが必要な加振力を１台の振動モータで得られる。
４、軸支持の位置を振動トラフの下流側に配置し、振動トラフ上流側の振幅を大きく、振動トラフ下流側の振幅を小さくする事により、搬送物の投入側の砂鋳型の破砕性を大きくでき、搬送物の搬出側の素材への打痕発生を低減できる。
５、軸支持の位置を変更する事により、一般的な振動コンベアに応用する事も可能である。
６、請求項２の発明においては、振動トラフ回転方向以外の振動力を相殺する２モータ構造とする事で軸支持に加わる振動モータの反力を低減する事が可能となる。 The effects of the present invention described above can be summarized as follows.
1. Since the structure is simple, it is easy to increase the strength.
2. Because the structure is simple, it is inexpensive.
3. By supporting one end of the vibration trough with a shaft, the vibration force required by two vibration motors can be obtained by one vibration motor based on the principle of leverage.
4. By arranging the position of the shaft support on the downstream side of the vibration trough, increasing the amplitude on the upstream side of the vibration trough and decreasing the amplitude on the downstream side of the vibration trough, the crushability of the sand mold on the loading side of the transported object is increased. This makes it possible to reduce the occurrence of dents on the material on the carry-out side of the transported object.
5. By changing the position of the shaft support, it can be applied to a general vibrating conveyor.
6. In the invention of claim 2, it is possible to reduce the reaction force of the vibration motor applied to the shaft support by adopting a two-motor structure that cancels the vibration force other than the vibration trough rotation direction.
