Description
本発明は、多数の小物ワークに研掃材を投射して研掃する装置および方法に関するものである。 The present invention relates to an apparatus and a method for polishing by projecting a polishing material onto a large number of small workpieces.
図5は、多数の小物ワークに研掃材を投射して研掃する従来例を示す模式図である。
図5(A)に描かれているように、バレル1の中に被研掃物2を入れ、その上方から研掃材投射機3によって矢印aのように研掃材を投射する。
投射され、研掃の役目を終えた研掃材を回収するため、前記のバレル1は多孔板で作られている。研掃材は矢印bのように落下し、コンベアやエレベータ(共に図示を省略)により、矢印cのように研掃材投射機3へ戻されて循環する。
FIG. 5 is a schematic view showing a conventional example in which a polishing material is projected onto a large number of small workpieces for polishing.
As illustrated in FIG. 5A, the object to be polished 2 is put in the barrel 1, and the abrasive is projected from above by the abrasive material projector 3 as indicated by an arrow a.
The barrel 1 is made of a perforated plate in order to collect the polished material that has been projected and has finished the role of scouring. The abrasive material falls as indicated by an arrow b, and is returned to the abrasive material projector 3 and circulated by an conveyer or an elevator (both not shown) as indicated by an arrow c.
バレル1内の被研掃物2は、均一に研掃されなければならない。
すなわち、1個の被研掃物について見れば、前後・左右・上下の各方向から均一に投射を受けねばならない。かつ、多数の被研掃物について見ても相互に同程度の研掃を受けねばならない。これは、多数の小物ワークに研掃材を投射して研掃する場合に共通する必要条件(特殊な例外を除く)である。
このため、バレル1内の被研掃物2を撹拌する手段が設けられる。
The object 2 to be polished in the barrel 1 must be evenly cleaned.
In other words, when looking at a single object to be studied, it must be uniformly projected from the front, rear, left, and right directions. In addition, even when looking at a large number of objects to be polished, the same level of cleaning must be performed. This is a common requirement (except for special exceptions) when abrading material is projected onto a large number of small workpieces.
For this purpose, means for stirring the object to be cleaned 2 in the barrel 1 is provided.
図5(B)は、前掲の(A)図の従来例を側面から見て描いた模式図である。
複数のプーリ4に、無端環状の多孔ベルト6が巻かけられて凹円柱面状のトラフ7を形成し、矢印e−e−eのように周回動している。該凹円柱面の端面は回転円板5で覆われている。この回転円板は、矢印dのように回転している。
トラフ7の中に入れられた被研掃物(図示省略)は多孔ベルト6の周回動によって掻き上げられ、矢印fのように撹拌されて転がる。
FIG. 5B is a schematic diagram illustrating the conventional example of FIG.
An endless perforated belt 6 is wound around a plurality of pulleys 4 to form a trough 7 having a concave cylindrical surface, and is rotated around as indicated by arrows ee-e. The end surface of the concave cylindrical surface is covered with a rotating disk 5. This rotating disk rotates as indicated by an arrow d.
The object to be polished (not shown) placed in the trough 7 is scraped up by the circumferential rotation of the perforated belt 6 and stirred and rolled as indicated by an arrow f.
図5を参照して以上に説明した従来例は広く実用されているが、多孔ベルト6が研掃材の投射を被るので早期に摩耗損傷し、ランニングコストが高い。
そこで無端環状ベルトの耐用命数を延ばすため、特許文献1として挙げた特開2005−297116号公報「研掃方法、および研掃装置」が開発されて好評を博している。
この発明は、簾(すだれ)状の金属製ベルトを用いたものである。
The conventional example described above with reference to FIG. 5 is widely used. However, since the perforated belt 6 is subjected to the projection of the abrasive, the wear damage occurs early and the running cost is high.
Therefore, in order to extend the service life of the endless annular belt, Japanese Patent Application Laid-Open No. 2005-297116 “Sweeping method and cleaning device” cited as Patent Document 1 has been developed and gained popularity.
The present invention uses a comb-like metal belt.
上記の公知発明に係る研掃装置は、無端環状ベルトが金属製であるから耐久性に優れているが、周回動するベルトと静止部材との間に、被研掃物の突起部が挟み込まれる虞れが有った。
こうした不具合を防止するため、図6に示した新規な研掃装置が開発された。
これは、本発明者が創作し、本出願人によって別途出願済みの発明(特願2006−24487・以下、未公知の先願に係る発明という)である。
The polishing apparatus according to the above known invention is excellent in durability because the endless annular belt is made of metal, but the protrusion of the object to be cleaned is sandwiched between the rotating belt and the stationary member. There was a fear.
In order to prevent such a problem, a new polishing apparatus shown in FIG. 6 has been developed.
This is an invention created by the present inventor and filed separately by the present applicant (Japanese Patent Application No. 2006-24487, hereinafter referred to as an invention related to an undisclosed prior application).
上方が開放された半割り形のバレル(8)に起振機10が装着されている。上記起振機を作動させると前記バレルが振動するので、これを振動バレル8と呼ぶ。符号9を付して示したのはスプリングであって、振動バレルを弾性的に支承している。
前記振動バレル8は枢支軸8dの周りに回動し得るようになっていて、
振動バレル8を図示の状態よりも右回り(時計方向)に約60度回動させて、その開口を上を向け、起振機10を作動させると、被研掃物2が撹拌される。すなわち個々の被研掃物が回転しながら、多数の被研掃物が渦状に流動する(流体物理学的な流動ではないが、これに類似した挙動を示す)。
The exciter 10 is mounted on a half-shaped barrel (8) whose upper side is open. Since the barrel vibrates when the vibrator is operated, this is called a vibration barrel 8. Reference numeral 9 denotes a spring, which elastically supports the vibration barrel.
The vibrating barrel 8 can be rotated around a pivot shaft 8d.
When the vibration barrel 8 is rotated about 60 degrees clockwise (clockwise) from the state shown in the drawing and the opening thereof is directed upward, and the vibrator 10 is operated, the object 2 is agitated. That is, as each object to be scanned rotates, a large number of objects to be swirled flow in a vortex (not a hydrophysical flow, but exhibit a similar behavior).
被研掃物を振動バレル8内で渦状に流動させながら図外の研掃材投射機から研掃材を投射して均一な研掃加工を施した後、次のようにして被研掃物を排出する。
図6に符号Hを付して示したのは水平線である。振動バレル8を図示の姿勢に回動させて、その底板に傾斜角θを与えると、被研掃物2が図の左下方へ排出される。ここで特徴的な現象は、傾斜角θが僅かであっても被研掃物が排出されることである。その理由は、振動を与えられた被研掃物が疑似的に流動するからである。
以上のようにして、耐久性に優れ、被研掃物の突起部が挟み込まれる虞れの無い、製品の搬出が容易な研掃装着が得られた。
In FIG. 6, a horizontal line is shown with a symbol H. When the vibration barrel 8 is rotated to the illustrated posture and the inclination angle θ is given to the bottom plate, the object 2 is discharged to the lower left in the figure. A characteristic phenomenon here is that the object to be cleaned is discharged even if the inclination angle θ is small. The reason is that the to-be-seen object to which vibration is applied flows in a pseudo manner.
As described above, it was possible to obtain a scouring attachment that is excellent in durability and that is easy to carry out the product without fear of the projecting portion of the scoured object being caught.
図6に示した未公知の先願に係る発明は、従来例に比して極めて優れた性能を有しているので、試験的使用者から感謝と称賛を戴いた。
本発明者は、前記未公知の先願に係る研掃装置を発明して特許出願した後、引き続いて鋭意研究開発を続けた結果、次に述べるように、更に改良する余地が有ることを確認した。
The invention according to the previously-disclosed prior application shown in FIG. 6 has excellent performance as compared with the conventional example, and thus received appreciation and praise from a trial user.
As a result of continuing research and development after the inventors filed a patent application after inventing the scouring device according to the previously unknown prior application, the present inventor confirmed that there is room for further improvement as described below. did.
図6から容易に理解されるように、この振動撹拌式研掃装置は、いわゆるバッチ式の作業が行われ、流れ作業は行われない。
すなわち、振動バレル8の中へ所定量の被研掃物を入れて研掃を施し、研掃工程を終えると図のようにして排出する。
この動作を何百回も何千回も繰り返して操業することにより、工業的な大量生産が遂行されることになる。
As can be easily understood from FIG. 6, this vibration agitation type scouring apparatus performs a so-called batch-type operation and does not perform a flow operation.
That is, a predetermined amount of the object to be polished is put into the vibration barrel 8 and subjected to polishing, and when the polishing process is completed, the object is discharged as shown in the figure.
By repeating this operation hundreds or thousands of times, industrial mass production is performed.
本発明は上述の事情に鑑みて為されたものであって、その目的は前記未公知の先願発明に係る振動撹拌式研掃装置について、その長所を損なうことなく更に改良し、流れ作業を可能ならしめることである。言うまでも無く、製造コストを増加させることなく、形状寸法や重量を増大させることなく、安全性や無公害性に問題を生じないことを前提としての改良を図るものである。 The present invention has been made in view of the above-mentioned circumstances, and the object thereof is to further improve the flow stirring work without impairing the advantages of the vibration agitation type polishing apparatus according to the above-mentioned unknown prior invention. Make it possible. Needless to say, improvements are made on the premise that there is no problem in safety and pollution-free, without increasing the manufacturing cost, without increasing the size and weight.
本発明の基本的な原理について、その1実施形態に対応する図2を参照して説明すると次の通りである。この[課題を解決するための手段]の欄は、図面との対照が容易なように括弧書きで図面符号を付記してあるが、この括弧付き符号は本発明の構成を図面のとおりに限定するものではない。
符号8を付して示したのは、図6(未公知の先願発明)におけると同様ないし類似の振動バレルである(起振機は図示を省略してある)。
(図2(A)参照)振動バレル8の片方の端(図において左端)に、被研掃物供給手段としてのシュート11が設けられるとともに、反対側の端(図において右端)には被研掃物搬出手段としての開口8eが設けられている。
The basic principle of the present invention will be described with reference to FIG. 2 corresponding to the first embodiment.

Not what you want.
Reference numeral 8 indicates a vibration barrel similar to or similar to that in FIG. 6 (unknown prior invention) (the vibrator is not shown).
(See FIG. 2 (A)) A
ここで注目すべきは、バレルに振動を与えるという新規な手段によって多数の被研掃物が疑似流動するということである。
従来技術においては、被研掃物は固形物であると考えられていたので、左端に供給した被研掃物が自分で右端まで歩いてくるとは夢にも思わなかった。しかし、振動を与えられて流動化した被研掃物群は、群の上面を水平に保とうとする作用が働き、搬出開口8eがシュート11の下端よりも低ければ、シュート11から搬出開口8eまで移動し、該開口8eから転落する(比喩的にいえば流れ落ちる)。
It should be noted here that a large number of objects to be studied are pseudo-flowed by a new means of applying vibration to the barrel.
In the prior art, the object to be studied was considered to be a solid substance, so it was not a dream that the object to be studied supplied to the left end would walk to the right end by itself. However, the to-be-scanned object group that has been fluidized by vibration acts to keep the upper surface of the group horizontal, and if the carry-out opening 8e is lower than the lower end of the
被研掃物2がシュートから開口8eまで移動する間に、ミクロに見た個々の被研掃物は自転し、マクロに見た被研掃物群は撹拌されて渦巻き流動しながら均一に研掃材の投射を受ける。
所定量の被研掃物を研掃加工し終えて作業を終了する際は、図2(C)のようにバレル底部の開口8gの扉16を開けば振動バレル内の被研掃物全部が排出される。
While the object to be studied 2 moves from the chute to the opening 8e, the individual objects to be examined seen microscopically rotate, and the group of objects to be examined seen macroscopically are stirred and uniformly polished while swirling. Receives sweeping material.
When the work is finished after a predetermined amount of the object to be polished is finished, if the door 16 of the opening 8g at the bottom of the barrel is opened as shown in FIG. Discharged.

図2(A)において振動バレル8が振動すると、その中に入れられている多数の被研掃物2が疑似流動性を示し、被研掃物群の上面がほぼ水平をなす。
このため、振動バレル8の右端付近の被研掃物は搬出開口8eから矢印iのように落下する。官能的には零れ落ちる感じであり、比喩的に言えば溢れて流れ出る。
上記の被研掃物排出作動を表している矢印iは、前掲の図1における矢印iに対応している。
When the vibrating barrel 8 vibrates in FIG. 2 (A), a large number of articles 2 to be studied show pseudo fluidity, and the upper surface of the group of objects to be studied is almost horizontal.
For this reason, the object to be polished near the right end of the vibration barrel 8 falls from the carry-out opening 8e as indicated by an arrow i. It feels spilling sensuously, and it overflows and flows in a metaphorical way.
The arrow i representing the above-described scoured object discharge operation corresponds to the arrow i in FIG.
多数の被研掃物からなる被研掃物群が疑似流動性を有していることを勘案すると、供給シュート11から搬入された被研掃物とほぼ同数の被研掃物が搬出開口8eから排出されることが理解される。
このようにして(比喩的に言えば)、供給シュート11から流れ込んだ被研掃物群は、
振動バレル8内で螺旋を描いて撹拌流動しながら搬出開口8eに向かい、定常的に送られてゆく。
Considering that the group of objects to be studied comprising a large number of objects to be studied has pseudo fluidity, the number of objects to be studied is almost the same as the number of objects to be studied that are carried in from the
In this way (in figurative terms), the group of objects to be studied flowing from the
While stirring and flowing in the vibration barrel 8, it is sent to the carry-out opening 8e and constantly sent.
個々の被研掃物2は、それぞれ自転しながら、供給シュート11からの供給量に比例した速さで図の右方へ移動する。このため、被研掃物2は均一な研掃を受ける。
(図1参照)研掃材の投射を表す2本の矢印aとa′とが厳密に等量でなくても、被研掃物2は振動バレル8内を左端から右端まで移動するから、均一な研掃を受けることになる。
本実施形態の振動撹拌式研掃機は、先に説明した未公知の先願に係る発明(図6)に比して、被研掃物の搬出が容易であるばかりでなく、多数の被研掃物に対する研掃加工が均一に行われるという優れた実用的効果を奏する。
Each object 2 to be studied moves to the right in the figure at a speed proportional to the supply amount from the
(See FIG. 1) Even if the two arrows a and a ′ representing the projection of the abrasive are not exactly equal, the object to be polished 2 moves from the left end to the right end in the vibration barrel 8. You will receive uniform cleaning.
Compared with the invention according to the previously-disclosed prior application (FIG. 6), the vibratory agitator type abrading machine of the present embodiment is not only easy to carry out the object to be studied but also has a large number of objects. An excellent practical effect is achieved in that the polishing of the polished material is performed uniformly.
図2(B)に示したように、振動バレル8に若干の傾斜を与えて設置することが推奨される。
上記の傾斜は、供給シュート11側を高くし、搬出開口8e側を低くする。このように傾斜させておくと、振動バレル8内における被研掃物2の渦巻き流動がいっそう円滑に行われる上、次に述べるように、研掃作業の終了操作に際して振動バレル内の被研掃物を容易に全部搬出できるので好都合である。
本発明者の実験研究によると、傾斜角度は0度〜15度の範囲に設定することが推奨される。
なお、図2(A)および図2(B)について以上に説明した作用効果から容易に理解し得るように、本実施形態における搬出開口8eは必ずしも名称どおりに「開口」の外観を有する構成部分であることを要せず、例えば切欠であっても良く、端面の壁が低くなっているだけでも良い。
As shown in FIG. 2B, it is recommended that the vibration barrel 8 be installed with a slight inclination.
The above inclination increases the
According to the inventor's experimental study, it is recommended that the tilt angle be set in the range of 0 to 15 degrees.
As can be easily understood from the operation and effects described above with reference to FIGS. 2A and 2B, the carry-out opening 8e in the present embodiment does not necessarily have the appearance of “opening” as the name indicates. For example, it may be a notch, or the end wall may be lowered.
予定数量の被研掃物2を研掃加工し終える際、若しくは夕刻の作業終了時刻に達した時など研掃作業を終了する場合は、図2(C)のように供給シュート11からの被研掃物供給を停止する。これにより、振動バレル8内の被研掃物2の量は次第に減少してゆく。
この場合、振動バレル8に前記の傾斜が付されていると、該振動バレルの中に入っていた被研掃物は、振動の作用と傾斜の作用とが相俟って自動的に、かつ円滑に矢印jのように排出される。
上記の被研掃物排出作動を表している矢印jは、前掲の図1における矢印jに対応している。
When the polishing work is to be completed, such as when the planned quantity of the object to be polished 2 is finished or when the evening work end time is reached, the object to be removed from the
In this case, if the inclination is given to the vibration barrel 8, the object to be cleaned contained in the vibration barrel is automatically combined with the action of the vibration and the action of the inclination, and It is discharged smoothly as shown by arrow j.
The arrow j representing the above-described scoured object discharge operation corresponds to the arrow j in FIG.
図1および図2を参照して以上に説明した作用から理解されるように、振動バレルに設けられている排出手段としての開口は、定常運転時には比較的高い位置に在り、作業終了時には比較的低い位置に在ることが必要である。
このように開口の位置を移動させるための具体的な構成について、以下に、その2例を挙げて説明する。
As can be understood from the operation described above with reference to FIGS. 1 and 2, the opening as the discharge means provided in the vibration barrel is at a relatively high position during steady operation, and is relatively low at the end of work. It is necessary to be in a low position.
A specific configuration for moving the position of the opening in this way will be described below with reference to two examples.
図3及び図4は、それぞれ搬出用開口の位置を変化させる機構を描いた側面図である。
図3の実施形態は、振動バレルの端面を形成している板状部材に開口を設け、この板状部材を回動させて開口位置の高さを変化させる方式であり、
図4の実施形態は、上,下に2個の開口を配置するとともに、下側の開口に設けた扉を開閉する方式である(この場合、上側の開口は開きっ放しにしておいても差し支え無い・詳細は後述する)。
3 and 4 are side views each illustrating a mechanism for changing the position of the carry-out opening.
The embodiment of FIG. 3 is a system in which an opening is provided in a plate-like member forming the end face of the vibration barrel, and the height of the opening position is changed by rotating the plate-like member.
The embodiment of FIG. 4 is a system in which two openings are arranged on the upper and lower sides, and a door provided in the lower opening is opened and closed (in this case, the upper opening may be left open). There is no problem. Details will be described later).
図3(A)は、図2(A)を図の右側から見たところを描いてある。ただし、図2(A)は模式図であり、図3(A)は実体的な外観図であるから、その差は念頭に置いて御覧いただきたい。
図2(A)においては、振動バレル8の右側端面を形成している壁がバレル本体と一体の部材であり、この壁板に搬出開口8eが穿たれているように描いてあるが、図3(A)の実施形態では振動バレル8の本体部分と別体の回転端板8cによってバレルの端面壁が形成されている。
FIG. 3 (A) is a drawing of FIG. 2 (A) viewed from the right side of the figure. However, FIG. 2 (A) is a schematic diagram, and FIG. 3 (A) is a substantial external view. Therefore, please keep this difference in mind.
In FIG. 2A, the wall forming the right end surface of the vibration barrel 8 is a member integral with the barrel main body, and the wall plate is depicted as having a carry-out opening 8e. In the embodiment 3 (A), the end face wall of the barrel is formed by the main body portion of the vibration barrel 8 and a separate rotating end plate 8c.
前記回転端板8cは枢支軸8dによって回動可能に支承され、図示しない駆動手段によって回動せしめ得るようになっている(振動バレル8の本体は回動しない)。
上記回転端板8cを図3(A)のように比較的高い位置ならしめると、図2(A)や図2(B)のように定常運転することができる。
図3(B)のように回転端板8cを付記円弧矢印のように回動させて搬出開口8eの位置を下げると、図2(C)に準じた状態になり、被研掃物を全部排出して研掃機の運転を終了することができる。
The rotary end plate 8c is rotatably supported by a pivot shaft 8d and can be rotated by a driving means (not shown) (the main body of the vibration barrel 8 does not rotate).
If the rotating end plate 8c is positioned relatively high as shown in FIG. 3A, steady operation can be performed as shown in FIGS. 2A and 2B.
When the rotary end plate 8c is rotated as shown by an additional circular arc arrow to lower the position of the carry-out opening 8e as shown in FIG. 3B, the state conforms to FIG. It can be discharged to finish the operation of the scourer.
図4も、開口位置の高さを変化させるための、前記と異なる実施形態である。
本図の(A)は側面図、(B)は部分的な正面断面図であり、(A),(B)両図で2面図を形成している。
この実施形態においては、振動バレル8の端面板が本体部分と一体に構成され、比較的高い位置に定位置開口8fが穿たれている。この定位置開口8fは移動せず、定常運転において被研掃物を排出する役目である。
FIG. 4 is also an embodiment different from the above for changing the height of the opening position.
(A) of this figure is a side view, (B) is a partial front sectional view, and (A) and (B) both figures form a two-sided view.
In this embodiment, the end face plate of the vibration barrel 8 is formed integrally with the main body portion, and a fixed position opening 8f is formed at a relatively high position. This fixed position opening 8f does not move and serves to discharge the object to be cleaned in a steady operation.
前記定位置開口8fよりも下方に、バレルの底面付近に位置せしめて扉付き開口8gが穿たれている。開閉扉16はシリンダ17によって開閉操作される。
前記開閉扉16を閉じれば、定位置開口8fから被研掃物を排出しながら定常運転を行なうことができる(図2(A)や図2(B)に示した運転状態)。
開閉扉16を開くと、図2(C)に描かれているように、バレル内の被研掃物を全部排出して運転を終了することができる。この場合、振動バレル8内の被研掃物の量が減少しているので、定位置開口8fが開いたままになっていても別段の支障は無い。
An opening 8g with a door is formed in the vicinity of the bottom surface of the barrel below the fixed position opening 8f. The opening / closing door 16 is opened and closed by a cylinder 17.
If the opening / closing door 16 is closed, the steady operation can be performed while discharging the object to be cleaned from the fixed position opening 8f (the operation state shown in FIGS. 2A and 2B).
When the open / close door 16 is opened, as shown in FIG. 2 (C), the entire object to be cleaned in the barrel can be discharged and the operation can be terminated. In this case, since the amount of the object to be cleaned in the vibration barrel 8 is reduced, there is no particular problem even if the fixed position opening 8f remains open.
