Description

この発明は、コアを担体としてその表面に研磨微粉を付着させてなる砥材に係り、繰り返しの使用により表面から研磨微粉が剥がれ落ちる等したコアに研磨微粉を再付着させる際に用いる砥材の再生装置並びにその再生方法に関するものである。   The present invention relates to an abrasive material in which abrasive fine powder is adhered to the surface using a core as a carrier. An abrasive material used for re-adhering abrasive fine powder to a core that has been removed from the surface by repeated use. The present invention relates to a playback apparatus and a playback method thereof.

本発明者は、鏡面仕上げ等に用いる砥材として、食物繊維や合成樹脂など弾発性を有する微粒状素材をコア（担体）とし、コア自体が有する粘着性あるいは適宜粘着剤を用い、コア表面に研磨微粉を付着させて砥材を生成する技術を既に考案している（例えば、特許文献１、２、３を参照）。同時に、この砥材を研磨対象物に吹き付けるための噴射装置も一連の技術として既に開示している（例えば、特許文献４、５、６を参照）。   The present inventor uses, as an abrasive used for mirror finish, etc., a core (carrier) made of a finely particulate material having elasticity such as dietary fiber or synthetic resin, and the core surface uses adhesive or an appropriate adhesive. Have already devised a technique for producing an abrasive by adhering fine abrasive powder (see, for example, Patent Documents 1, 2, and 3). At the same time, an injection device for spraying the abrasive on the object to be polished has already been disclosed as a series of techniques (see, for example, Patent Documents 4, 5, and 6).

ところで、上記砥材は研磨使用を続けるに従って、表面層である研磨微粉が徐々に剥がれ出し、その下層の粘着層が露出するなどして、研磨性能が低下してくる。このような場合、コア自体は弾発性、また素材によっては粘着性を失わない限り、そのまま利用することができるから、再びコア表面に研磨微粉を付着させることによって、砥材を再生することができる。その方法として現行では、研磨微粉が剥がれたコアを噴射装置から外部に取り出し、回転ドラム内で研磨微粉と混合させることにより、再度、コア表面に研磨微粉を付着させて砥材の再生を図っていた。   By the way, as the polishing material continues to be used for polishing, the polishing fine powder which is the surface layer gradually peels off, and the adhesive layer underneath is exposed, so that the polishing performance deteriorates. In such a case, the core itself can be used as long as it does not lose elasticity or, depending on the material, so that it is possible to regenerate the abrasive by attaching abrasive fine powder to the core surface again. it can. At present, as a method for this, the core from which the abrasive fine powder has been peeled is taken out from the injection device and mixed with the abrasive fine powder in the rotating drum, so that the abrasive fine powder is adhered to the core surface again to regenerate the abrasive. It was.

しかしながら、回転ドラムによって混合する上記従来の再生方法では、一度使用したコアの表面粘度に再生前後で差が生じるなど、結果的に研磨微粉の付着が不均一となり、一定の研磨性能を得ることができなかった。   However, in the above-described conventional regeneration method in which mixing is performed by a rotating drum, the surface viscosity of the core once used is different between before and after the regeneration. As a result, the adhesion of the abrasive fine powder becomes non-uniform, and a certain polishing performance can be obtained. could not.

本発明は上述した課題を解決するためになされたもので、常に一定の研磨性能を得ることを目的として、鋭意考究・実験を重ねた結果、研磨微粉の流動性の低さを克服して、少量ずつ研磨微粉をコアに供給することで研磨微粉を均一に付着させ得ることを見出したものである。   The present invention was made to solve the above-mentioned problems, and as a result of repeated earnest studies and experiments for the purpose of always obtaining a certain polishing performance, the low fluidity of the polishing fine powder was overcome, It has been found that the polishing fine powder can be uniformly attached by supplying the fine powder to the core little by little.

即ち、本発明では、少量の研磨微粉を一定間隔で供給するための具体的手段として、コアを担体としてその表面に研磨微粉を付着させてなる砥材の再生装置であって、函体の下面に前記研磨微粉の落下排出口を設けてなる研磨微粉の貯留手段と、該貯留手段の落下排出口と間欠的に連通して一定量の研磨微粉を通過させる第一のゲートと、該第一のゲートを介して前記貯留手段の落下排出口と連通し、前記一定量の研磨微粉を一時的に貯留する受け手段と、前記第一のゲートとは異なるタイミングにより前記受け手段と間欠的に連通して当該受け手段から前記一時的に貯留した研磨微粉を通過させる第二のゲートとから砥材の再生装置を構成するという手段を用いた。   That is, in the present invention, as a specific means for supplying a small amount of abrasive fine powder at regular intervals, an abrasive regenerator comprising a core as a carrier and adhering abrasive fine powder to the surface thereof, the lower surface of the box A polishing fine powder storing means provided with a falling discharge port for the polishing fine powder, a first gate that intermittently communicates with the falling discharge port of the storage means and allows a certain amount of the polishing fine powder to pass therethrough, and the first The receiving means communicates with the drop discharge port of the storage means via the gate, and intermittently communicates with the receiving means at timings different from the receiving means for temporarily storing the fixed amount of polishing fine powder. Then, a means for constituting an abrasive regenerator from the second gate for passing the temporarily stored polishing fine powder from the receiving means was used.

また請求項２では、第一のゲートと第二のゲートは、通孔を形成した上板と、前記通孔とは非連通な落下孔を形成した下板とでなり、これら上板と下板を水平に往復動させて通孔と落下孔を異なるタイミングにより受け手段と連通させるスライド手段を設けるという手段を選択的に用いることとした。   According to a second aspect of the present invention, the first gate and the second gate are composed of an upper plate in which a through hole is formed and a lower plate in which a drop hole that is not in communication with the through hole is formed. A means of selectively providing slide means for horizontally reciprocating the plate to provide communication between the through hole and the drop hole with the receiving means at different timings was used.

さらに請求項３では、第一のゲートと第二のゲートをそれぞれ天板および底板として、そのクリアランスよりも大きく設定される直径の円筒部材から受け手段を構成した。   Further, in claim 3, the first gate and the second gate are the top plate and the bottom plate, respectively, and the receiving means is composed of a cylindrical member having a diameter set larger than the clearance.

一方、別手段として本発明では、函体の下方側面に排出口を設けた前記研磨微粉の貯留手段と、前記排出口から先方一部を突出させた状態で前記貯留手段に内蔵されるスクリューコンベアと、貯留手段の研磨微粉を前記排出口に向かって押出す方向に前記スクリューコンベアを回転させる駆動手段とから砥材の再生装置を構成することもある。この手段は、スクリューコンベアのオーガの回転数やスパイラルな歯の大きさを適宜調整することによって、貯留手段内の研磨微粉を強制的に少量ずつ排出口から排出する作用を行う。これに対して、ゲート手段を用いた上記手段では、該ゲート手段により排出口から自然落下しようとする研磨微粉を少量ずつ排出する作用を行うが、何れも研磨微粉を一定量ずつ排出させる点では機能が一致する。なお、本発明でいう研磨微粉の貯留手段の具体的構成としては、函体胴部の下方が徐々に窄まるホッパが該当する。但し、この構成においても排出口は函体の下方に設けられるため、流動性の低い研磨微粉を効果的に排出口に導くために、本発明ではホッパ等の貯留手段に断続的または間欠的に振動または衝撃を付与する装置を付設するという手段を選択的に用いる。   On the other hand, as another means, in the present invention, the polishing fine powder storage means provided with a discharge port on the lower side surface of the box, and a screw conveyor built in the storage means in a state where a part of the front end protrudes from the discharge port. And a drive unit for rotating the screw conveyor in a direction for extruding the abrasive fine powder of the storage unit toward the discharge port, and a polishing material regenerating device may be configured. This means performs the action of forcibly discharging the abrasive fine powder in the storage means little by little from the outlet by appropriately adjusting the rotational speed of the auger of the screw conveyor and the size of the spiral teeth. On the other hand, in the above means using the gate means, the gate means performs the action of discharging small amounts of the abrasive fine powder that is about to fall naturally from the discharge port. The functions match. In addition, as a specific structure of the means for storing abrasive fine powder as referred to in the present invention, a hopper in which the lower portion of the box body is gradually narrowed corresponds. However, even in this configuration, since the discharge port is provided below the box, in the present invention, the storage means such as a hopper is intermittently or intermittently introduced in order to effectively guide the abrasive powder having low fluidity to the discharge port. A means of attaching a device for applying vibration or impact is selectively used.

他方、砥材の再生方法として本発明では、研磨微粉の貯留手段に設けた排出口から一定量ずつ研磨微粉を排出させることとし、その具体的手段として、通孔を形成したゲートを水平に往復動させて貯留手段の落下排出口を間欠的に開閉するか、もしくは、排出口から先方一部を突出した状態でスクリューコンベアを貯留手段に内蔵し、該スクリューコンベアを一定方向に回転させるという手段を用いる。またゲート手段を採用した方法において、ゲートを通過した研磨微粉を一時的に貯留し、その後、前記通過とは異なるタイミングにより前記一時的に貯留した研磨微粉の落下を許容する別のゲートを設けるという手段も用いる。   On the other hand, in the present invention as a method for regenerating the abrasive, the polishing fine powder is discharged from the discharge port provided in the polishing fine powder storage means by a certain amount, and as a specific means, the gate in which the through hole is formed is reciprocated horizontally. Means to intermittently open and close the drop discharge port of the storage means, or to store the screw conveyor in the storage means in a state where a part of the tip protrudes from the discharge port, and to rotate the screw conveyor in a certain direction Is used. In the method employing the gate means, the polishing fine powder that has passed through the gate is temporarily stored, and then another gate that allows the temporarily stored polishing fine powder to fall at a timing different from the passage is provided. Means are also used.

上述の通り、本発明によれば、間欠的に動作するゲート手段またはオーガの大きさや回転数を適宜調整可能なスクリューコンベアを用いることにより、流動性の低い研磨微粉を貯留手段から一定量ずつ取り出すことができるため、この手段により研磨微粉をコアに一定の間隔で加え続けることで、コア表面に研磨微粉を均一に付着させることができ、常に一定の研磨性能を有する砥材として再生することができる。また、ゲート手段として、通孔と落下孔を偏心させた２枚の上下板を同時にスライドさせることとしたので、簡易な構成で再生装置を構成することができる。さらに、受け手段は第一のゲートと第二のゲートをそれぞれ天板および底板として、そのクリアランスよりも大きく設定される直径の円筒部材により構成したので、装置の簡素化を図りつつ、より確実に研磨微粉を一定量ずつ供給することができるという合理性がある。   As described above, according to the present invention, by using a gate means that operates intermittently or a screw conveyor that can appropriately adjust the size and rotation speed of the auger, a small amount of abrasive fine powder having low fluidity is taken out from the storage means. Therefore, by continuing to add the polishing fine powder to the core at a constant interval by this means, the polishing fine powder can be uniformly attached to the core surface and can always be regenerated as an abrasive having a constant polishing performance. it can. Further, since the two upper and lower plates having the through hole and the drop hole eccentrically slid as the gate means at the same time, the reproducing apparatus can be configured with a simple configuration. Furthermore, since the receiving means is constituted by a cylindrical member having a diameter larger than the clearance, with the first gate and the second gate as the top plate and the bottom plate, respectively, the device can be simplified and more reliably. There is a rationality that a certain amount of polishing fine powder can be supplied.

以下、本発明の好ましい実施の形態を添付した図面に従って説明する。先ず、本発明は、研磨微粉を貯留した貯留手段の排出口から研磨微粉を一定量ずつ排出させるという方法を採用し、その具体的手段として、通孔を形成したゲートを水平にスライドさせて貯留手段の落下排出口を間欠的に開閉させ、また、前記ゲートを通過した研磨微粉を一時的に貯留し、その後、前記通過とは異なるタイミングにより前記一時的に貯留した研磨微粉を間欠的に落下さ得る別のゲートを設けるという手段を用いる。図１、２は当該方法を装置化した第一の実施形態に係る本発明再生装置であり、図中、１は研磨微粉の貯留手段であるホッパであって、円筒状胴部１ａの下部に研磨微粉の流動勾配を有する逆円錐状流出部１ｂを設けると共に、流出部１ｂの下面に設けた落下排出口１ｃから研磨微粉を落下させ得るものである。なお、研磨微粉は０．１〜１０μｍと非常に粒度が高く、流動性が低い。このため流出部１ｂの勾配により自然落下のみではホッパ１から研磨微粉を取り出しにくいことがある。そこで、本実施形態ではホッパ１の胴部１ａにバイブレータ２を付設し、間欠的または継続して発生する微振動により研磨微粉に流動性を与え、落下排出口１ｃから研磨微粉を取り出しやすくしている。ただし、バイブレータ２に代えて、他の振動または衝撃を加えることができるハンマー等の装置を付設してもよい。また、研磨微粉の粒度は前記数字に限定するものではないため、バイブレータ２等の振動等装置もその流動性に応じて適宜採否を決定すればよい。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, the present invention adopts a method of discharging a certain amount of polishing fine powder from a discharge port of a storage means that stores polishing fine powder, and as a specific means thereof, the gate having a through hole is slid horizontally for storage. The dropping outlet of the means is intermittently opened and closed, and the polishing fine powder that has passed through the gate is temporarily stored, and then the temporarily stored polishing fine powder is intermittently dropped at a timing different from the passage. A means of providing another gate that can be used is used. 1 and 2 show the present invention regenerating apparatus according to the first embodiment in which the method is implemented. In the figure, reference numeral 1 denotes a hopper which is a means for storing abrasive fine powder, and is disposed below the cylindrical body 1a. While providing the reverse cone-shaped outflow part 1b which has the flow gradient of polishing fine powder, polishing fine powder can be dropped from the fall discharge port 1c provided in the lower surface of the outflow part 1b. The fine abrasive powder has a very high particle size of 0.1 to 10 μm and low fluidity. For this reason, it may be difficult to take out the polishing fine powder from the hopper 1 only by natural fall due to the gradient of the outflow portion 1b. Therefore, in the present embodiment, the vibrator 2 is attached to the body portion 1a of the hopper 1, and fluidity is given to the abrasive fine powder by the minute vibration generated intermittently or continuously, so that the abrasive fine powder can be easily taken out from the fall discharge port 1c. Yes. However, instead of the vibrator 2, a device such as a hammer that can apply other vibrations or impacts may be provided. In addition, since the particle size of the abrasive fine powder is not limited to the above numbers, a vibration or other device such as the vibrator 2 may be determined as appropriate depending on the fluidity.

次に、３はゲート手段であって、全長に比べて全高が短く、半ば板状の外観を呈する横長の函体の上板３ａにホッパ１の落下排出口１ｃと連通可能な通孔３ｂを形成して第一ゲートとすると共に、底板３ｃに上記通孔３ｂとは連通しないように中心軸を偏心した落下孔３ｄを形成することにより第二のゲートとしたものである。また当該ゲート３は、箱状部材として一体構造となっている第一のゲートと第二のゲートをエアピストン等を駆動源とするスライド手段４により長手方向に移動させることによって、後述する通孔３ｂおよび落下孔３ｄの連通動作を間欠的に行うものである。   Next, reference numeral 3 denotes gate means, which has a through hole 3b that can communicate with the drop discharge port 1c of the hopper 1 on an upper plate 3a of a horizontally long box that has a short overall height and has a half plate-like appearance. The first gate is formed, and the second gate is formed by forming a drop hole 3d having an eccentric central axis so as not to communicate with the through hole 3b in the bottom plate 3c. The gate 3 is a through-hole, which will be described later, by moving the first gate and the second gate, which are integrated as a box-shaped member, in the longitudinal direction by the slide means 4 using an air piston or the like as a drive source. The communication operation of 3b and the drop hole 3d is performed intermittently.

さらに、５はゲート手段３に内包された研磨微粉の一時的な受け手段であって、上下面が開放された円筒状部材からなる。この受け手段５の上面開口５ａは、前記通孔３ｂを介してホッパ１の落下排出口１ｃと連通可能であると共に、下面開口５ｂは前記落下孔３ｄと連通可能な内径に設定されている。なお、ゲート手段３は、上述のようにスライド手段４により左右にスライド（往復動）するが、この動作中であっても受け手段５は、図示しない固定手段によって、常にホッパ１の落下排出口１ｃと連通する位置に停止している。   Further, 5 is a means for temporarily receiving the fine polishing powder contained in the gate means 3, and is composed of a cylindrical member whose upper and lower surfaces are open. The upper surface opening 5a of the receiving means 5 can be communicated with the drop discharge port 1c of the hopper 1 through the through hole 3b, and the lower surface opening 5b is set to have an inner diameter capable of communicating with the drop hole 3d. The gate means 3 slides left and right (reciprocates) by the slide means 4 as described above. Even during this operation, the receiving means 5 always keeps the drop outlet of the hopper 1 by the fixing means (not shown). It stops at a position communicating with 1c.

続いて、上記再生装置の動作を図３を含め説明する。先ず、ゲート手段３が図２に示すように、第一のゲート、即ち上板３ａの通孔３ｂを介してホッパ１の落下排出口１ｃと受け手段５の上面開口５ａが連通可能な状態にあるとき（図３（ａ）参照）、ホッパ１に貯留された研磨微粉は、円錐状流出部１ｂの流動勾配やバイブレータ２の微振動により、落下排出口１ｃから第一のゲート（通孔３ｂ）を介して、連通時間に応じ、且つ、最大で受け手段の内容積に応じた一定量だけ受け手段５に充填される。次に、スライド手段４を駆動させ、ゲート手段３をスライド（本実施形態の場合、図面右に向かって）させると、ホッパ１の落下排出口１ｃと第一のゲートである上板３ａの通孔３ｂとの連通が絶たれ、同時に上板３ａがホッパ１の落下排出口１ｃを閉塞する結果、この段階でホッパ１からの受け手段５に対する研磨微粉の充填動作が終了する（図３（ｂ）参照）。そして、同方向にゲート手段３をさらにスライドさせれば、受け手段５の下面開口５ｂが第二のゲートである下板３ｃの落下孔３ｄと連通することになり（図３（ｃ）参照）、受け手段５に一時的に充填されていた研磨微粉が落下孔３ｄから排出される。この後、スライド手段によりゲート手段３を反対側にスライドさせ、図２・図３（ａ）の位置に復帰させることにより、上述した研磨微粉の充填動作がなされる。こうしたスライド手段４によるゲート手段３の往復動を継続することで、ホッパ１の研磨微粉を間欠的に一定量ずつコアに対して供給し続けることができるのである。   Next, the operation of the playback apparatus will be described with reference to FIG. First, as shown in FIG. 2, the gate means 3 is in a state in which the drop discharge port 1c of the hopper 1 and the upper surface opening 5a of the receiving means 5 can communicate with each other through the first gate, that is, the through hole 3b of the upper plate 3a. In some cases (see FIG. 3 (a)), the polishing fine powder stored in the hopper 1 flows from the drop discharge port 1c to the first gate (through hole 3b) due to the flow gradient of the conical outflow portion 1b and the fine vibration of the vibrator 2. ), The receiving means 5 is filled by a certain amount corresponding to the communication time and at most the internal volume of the receiving means. Next, when the sliding means 4 is driven and the gate means 3 is slid (toward the right in the drawing in the case of this embodiment), the drop discharge port 1c of the hopper 1 and the upper plate 3a which is the first gate pass through. As a result of the disconnection with the hole 3b and the upper plate 3a simultaneously closing the drop outlet 1c of the hopper 1, the filling operation of the polishing fine powder from the hopper 1 to the receiving means 5 is completed (FIG. 3 (b)). )reference). If the gate means 3 is further slid in the same direction, the lower surface opening 5b of the receiving means 5 communicates with the drop hole 3d of the lower plate 3c which is the second gate (see FIG. 3C). Then, the polishing fine powder temporarily filled in the receiving means 5 is discharged from the drop hole 3d. Thereafter, the gate means 3 is slid to the opposite side by the slide means and returned to the position shown in FIGS. 2 and 3A to perform the above-described polishing fine powder filling operation. By continuing the reciprocating motion of the gate means 3 by the slide means 4, it is possible to continue supplying the polishing fine powder of the hopper 1 to the core intermittently by a certain amount.

図４は、本発明の第二実施形態に係る再生装置を示したもので、この実施形態では貯留手段から研磨微粉を少量ずつ取り出す構成として、上記第一実施形態における自然落下可能な貯留手段にゲート手段を設けた構成に代え、下方側面に排出口１０を設けた貯留手段２０に研磨微粉を強制排出するスクリューコンベア３０を内蔵した構成を採用している。より具体的には、貯留手段２０として角形ホッパを採用し、その下方側面に排出口１０を形成すると共に、該排出口１０に円筒状の取り出し部１１を突設し、先方一部を排出口１０から突出した状態で、且つ、軸を水平若しくは頭下がりの斜めとした姿勢で、スクリューコンベア３０を貯留手段２０に内蔵している。そして、スクリューコンベア３０をモータ等の駆動手段４０により回転させることで、貯留手段２０内の研磨微粉を少量ずつ強制的に排出口１０を介して取り出し部１１から排出させることができるのである。なお、この構成における研磨微粉の排出量は、スクリューコンベア３０のオーガの大きさや間隔、回転速度によって調整することができる。また、駆動手段４０を制御することによって、スクリューコンベア３０を間欠的に回転させることも、断続的に回転させることもできる。さらに、貯留した研磨微粉の滞留を防止するために貯留手段２０に振動装置５０を付設できることは、上記第一実施形態と同じである。   FIG. 4 shows a regenerator according to the second embodiment of the present invention. In this embodiment, the storage means in the first embodiment is configured so as to take out the abrasive fine powder little by little from the storage means. Instead of the configuration in which the gate means is provided, a configuration is adopted in which a screw conveyor 30 for forcibly discharging the abrasive fine powder is stored in the storage means 20 in which the discharge port 10 is provided on the lower side surface. More specifically, a rectangular hopper is adopted as the storage means 20, the discharge port 10 is formed on the lower side surface thereof, and a cylindrical take-out portion 11 is projected from the discharge port 10, and a part of the tip is discharged to the discharge port 10. The screw conveyor 30 is built in the storage means 20 in a state of protruding from 10 and in a posture in which the axis is horizontal or slanted downward. Then, by rotating the screw conveyor 30 by the driving means 40 such as a motor, the abrasive fine powder in the storage means 20 can be forcibly discharged from the take-out portion 11 through the discharge port 10 little by little. In addition, the discharge amount of the polishing fine powder in this configuration can be adjusted by the size and interval of the auger of the screw conveyor 30 and the rotation speed. Further, by controlling the driving means 40, the screw conveyor 30 can be rotated intermittently or intermittently. Furthermore, it is the same as the first embodiment that the vibration device 50 can be attached to the storage means 20 in order to prevent the stored abrasive fine powder from staying.

なお、本装置は砥材を再生（場合によっては生成）するために研磨微粉を一定量ずつ供給するものであるため、本装置はコアと研磨微粉を撹拌または混合する装置（図示なし）の上方に設置される。例えば、本出願人が開示した従来技術の砥材噴射装置にあっては、作業室の下にフィーダを設け、一度噴射した砥材を回収し、再度羽根車に供給する構造を有するが、この場合、前記回収装置に対して本発明の再生装置を組み込むことで、砥材再生機能付きの噴射装置を構成することができる。その他、従来の撹拌もしくは混合装置に本装置を組み込めば、砥材の再生を含む砥材生成装置を構成することも可能である。このとき、研磨微粉の付着性等を付与するために、研削液（油）や粘着剤等のバインダ、あるいは水を公知の手段によって適宜加えることがあることはもちろんである。   In addition, since this apparatus supplies a fixed amount of fine abrasive powder to regenerate (in some cases, generate) the abrasive, this apparatus is located above a device (not shown) that stirs or mixes the core and the fine abrasive powder. Installed. For example, the prior art abrasive material injection device disclosed by the present applicant has a structure in which a feeder is provided under the working chamber, and once injected abrasive material is collected and supplied to the impeller again. In this case, an injection device with an abrasive material regeneration function can be configured by incorporating the regeneration device of the present invention into the recovery device. In addition, if this apparatus is incorporated into a conventional stirring or mixing apparatus, it is also possible to configure an abrasive material generating apparatus including regeneration of an abrasive material. At this time, it is needless to say that a binder such as a grinding fluid (oil) or an adhesive, or water may be appropriately added by a known means in order to impart adhesion of the abrasive fine powder.
