Description

本発明はバリ取りを行なう処理物が大型で、大量に処理する場合に使用する大型にしたショットブラスト装置に関する。   The present invention relates to a shot blasting apparatus having a large size to be used for processing a large amount of a deburring object.

従来のショットブラスト装置は、小さな成型品に付着している微細なバリを除去する場合に使用されている。
しかしながら、最近、大きな成型品に付着しているバリを除去するのに使用したいという話があり、この対策としてバレルの大型化、投射材、投射機の大型化で対応しているが、このような対策ではバレル内の撹拌板は長方形状の板であるため、処理物の大きさに合わせて大型化すると、投射材の妨げになったり、撹拌板の取付け角度はバレルの底面に対して垂直に取付けてあるため、処理物が撹拌板に乗り上がらず、十分な撹拌ができないという欠点があった。 A conventional shot blasting apparatus is used to remove fine burrs adhering to a small molded product.
However, recently, there is a story that I want to use it to remove burrs attached to large molded products, and as measures against this, we have responded by increasing the size of the barrel, the size of the projection material, and the size of the projector. As a countermeasure, the stirring plate in the barrel is a rectangular plate, so if the size of the stirring plate is increased to match the size of the workpiece, the projection material may be obstructed, and the mounting angle of the stirring plate should be perpendicular to the bottom of the barrel. Therefore, there is a drawback in that the processed product does not ride on the stirring plate and cannot be sufficiently stirred.

特開２００４−２０９６０４号公報JP 2004-209604 A

本発明は以上のような従来の欠点に鑑み、大型のバレル内でも処理物に効率よく投射材を投射できるとともに、処理物を効率よく撹拌することができ、バリ取り作業を効率よく行なうことができるショットブラスト装置を提供することを目的としている。   In view of the above-described conventional drawbacks, the present invention can efficiently project a projection material on a processed object even in a large barrel, can efficiently stir the processed object, and can efficiently perform a deburring operation. An object of the present invention is to provide a shot blasting device that can be used.

本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。 The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明はブラスト処理室内に傾斜状態で回転するバレルが設けられたショットブラスト装置において、前記バレルの内壁面に、該バレルの投入口側の先端部より、底面側の後端部が回転方向に先に位置するように傾斜状態で固定された撹拌板本体と、この撹拌板本体の後端部側を除く部位の先端部に形成された、該撹拌板本体に乗った処理物を前記バレルの底面方向へ案内する返し板とからなる撹拌板を設けてショットブラスト装置を構成している。   In order to achieve the above object, the present invention provides a shot blasting apparatus in which a barrel that rotates in an inclined state is provided in a blasting processing chamber, wherein the inner wall surface of the barrel is closer to the bottom side than the front end portion on the inlet side of the barrel. The stirring plate main body fixed in an inclined state so that the rear end of the stirring plate is positioned first in the rotation direction, and the stirring plate main body formed at the tip of the portion excluding the rear end side of the stirring plate main body. A shot blasting apparatus is configured by providing a stirring plate including a return plate that guides the processed product on the bottom of the barrel.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。
（１）請求項１により、撹拌板本体に乗った処理物を返し板によって、該撹拌板本体から脱落するのを防止できるとともに、バレルが回転して撹拌板本体が上方へ移動することにより、処理物は撹拌板本体上を滑って、バレルの底面へ落下させることができる。
したがって、処理物を回転方向に移動させるとともに、バレルの投入口側から底面方向（前後方向）の移動ができ、効率よく撹拌することができる。
（２）前記（１）により、撹拌板本体をバレルの内壁面に、該バレルの投入口側の先端部より底面側の後端部が、回転方向が先に位置するように傾斜状態で固定されているので、処理物の前後方向に効率よく移動させることができる。
したがって、処理物の撹拌効果の向上を図ることができる。
（３）前記（１）により、構造が簡単で、安価に設置することができる。
（４）請求項２も前記（１）〜（３）と同様な効果が得られるとともに、返し板の脱落防止部によって、処理物をさらに効率よく撹拌することができる。
（５）請求項３も前記（１）〜（３）と同様な効果が得られるとともに、バレルの底面の中央部が内側へ突出する円錐、円錐台形状、多角錐あるいは多角錐台形状に形成されているので、処理物をより効率よく撹拌することができる。 As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, the processed product on the stirring plate main body can be prevented from falling off from the stirring plate main body by the return plate, and the barrel rotates to move the stirring plate main body upward. The treated product can slide on the stirring plate body and drop to the bottom of the barrel.
Therefore, while moving a processed material to a rotation direction, it can move to a bottom face direction (front-back direction) from the inlet side of a barrel, and can stir efficiently.
(2) According to (1), the stirring plate body is fixed to the inner wall surface of the barrel in an inclined state so that the rear end portion on the bottom surface side of the front end portion on the inlet side of the barrel is positioned first. Therefore, it is possible to efficiently move the processed material in the front-rear direction.
Therefore, it is possible to improve the effect of stirring the processed material.
(3) According to (1), the structure is simple and can be installed at low cost.
(4) In the second aspect, the same effects as in the above (1) to (3) can be obtained, and the processed product can be more efficiently agitated by the fall-off prevention part of the return plate.
(5) Claim 3 also has the same effects as the above (1) to (3), and is formed in a cone, truncated cone shape, polygonal pyramid or polygonal frustum shape in which the central portion of the bottom surface of the barrel projects inward. Therefore, the processed product can be stirred more efficiently.

It consists of

前記大型バレル１０は八角形状で、上下部が小径となる多数個の孔２１が形成された八角筒状のバレル本体２２と、このバレル本体２２の底面を覆う中央部が内側へ突出する円錐、円錐台形状、多角錐あるいは多角錐台形状に形成された底板２３と、前記バレル本体２２の内壁面に、該バレル本体２２の投入口８側の先端部２４ａより、底面側の後端部２４ｂが、回転方向が先に位置するように傾斜２５状態で固定されたほぼ三角形状の撹拌板本体２４、この撹拌板本体２４の後端部２４ｂ側を除く部位の先端部に形成された、該撹拌板本体２４に乗った処理物１１を前記バレル本体２２の底面方向に案内する返し板２６、この返し板２６のバレル本体２２の投入口８側の先端部に折り曲げ形成された脱落防止部２７とからなる撹拌板２８とで構成されている。   The large barrel 10 has an octagonal shape, an octagonal cylindrical barrel body 22 in which a large number of holes 21 whose upper and lower portions have a small diameter are formed, and a cone whose central portion covering the bottom surface of the barrel body 22 projects inward. A bottom plate 23 formed in a truncated cone shape, a polygonal pyramid or a polygonal frustum shape, and an inner wall surface of the barrel main body 22, a rear end portion 24 b on the bottom surface side from a front end portion 24 a on the inlet 8 side of the barrel main body 22. However, the substantially triangular stirring plate main body 24 fixed in the inclined 25 state so that the rotation direction is located first, the tip portion of the portion excluding the rear end portion 24b side of the stirring plate main body 24 is formed, A return plate 26 that guides the processed material 11 on the stirring plate main body 24 toward the bottom surface of the barrel main body 22, and a drop-off prevention portion 27 that is bent and formed at the tip end of the barrel main body 22 on the inlet 8 side. A stirring plate 28 consisting of It is configured.

上記構成のショットブラスト装置１は上部開閉扉３を開放し、大型バレル１０の投入口８より大型の処理物１１を投入し、上部開閉扉３を閉じる。   The shot blasting apparatus 1 having the above-described configuration opens the upper opening / closing door 3, loads a large processed material 11 from the charging port 8 of the large barrel 10, and closes the upper opening / closing door 3.

しかる後、必要に応じてブラスト処理室４内に冷媒供給装置２０の開閉弁２９を開放して冷媒を供給し、投射機１４、回転駆動装置９および選別装置１５を駆動させると、大型バレル１０が回転するとともに、投射機１４のインペラー１３によって、選別装置１５で選別された投射材１２を大型バレル１０内の処理物１１に投射して、バリを除去する。   Thereafter, if necessary, the on-off valve 29 of the refrigerant supply device 20 is opened in the blast treatment chamber 4 to supply the refrigerant, and the projector 14, the rotation drive device 9 and the sorting device 15 are driven. , And the impeller 13 of the projector 14 projects the projection material 12 sorted by the sorting device 15 onto the processed object 11 in the large barrel 10 to remove burrs.
