[Industrial application field]

本考案は、例えば塗装表面をサンディングして補修するような際、サンディングで生ずる研削カスを吹き払うようにした除塵サンダに関する。 This invention is useful for sanding and repairing, for example, painted surfaces. This invention relates to a dust removal sander that blows away grinding scum generated during sanding.

[Conventional technology]

従来、例えば車両の塗装工程において、塗装表面に異物が混入したり、色ムラが生じたような場合は、局部的にサンドペ−パ等によって削り取って補修する。このため例えば実開昭５９−１８３３５０号に示されるようなサンダで要修理箇所の塗装表面を研削した後、再塗装等をし直す訳であるが、研削時に生ずる研削カスは、サンディング終了後エア−ブロ−で吹き払うか或いは実開昭６１−１５９０７４号、実開昭６１−５５９７７号のようにエアを吹き付けて舞い上がったカスを静電作用で吸着させる等の措置により処理している。 Conventionally, for example, in the painting process of vehicles, foreign matter got mixed into the painted surface and color unevenness occurred. If this occurs, remove it locally with sandpaper, etc. to repair it. For this reason, for example, as shown in Utility Model Application Publication No. 59-183350, parts requiring repair can be removed using a sander. After grinding the painted surface, it is repainted, etc., but the grinding that occurs during grinding After sanding, blow away the residue with an air blower or No. 9074, it flew up by blowing air like No. 61-55977. The waste is disposed of using measures such as electrostatic adsorption.

[Means to solve the problem]

かかる課題を解決するため、本考案は、送気管からのエアで回転するロ−タと、このロ−タの回転軸に連結される研摩体を備えたサンダにおいて、前記ロ−タの回転軸まわりに環状のエア配管を設け、このエア配管の途中から複数の分岐管を放射状に分岐させ、下向きに開口させた。そして環状のエア配管と前記送気管を流量調整弁を介して連通させた。 In order to solve this problem, the present invention uses a rotor that rotates with air from the air pipe. , a sander equipped with an abrasive body connected to a rotating shaft of the rotor, in which the rotor An annular air pipe is installed around the rotation axis, and multiple branch pipes are connected from the middle of this air pipe. It was branched radially and opened downward. and an annular air pipe and the air pipe were communicated via a flow rate regulating valve.

[Effect]

送気管からエアを送気してロ−タを回転させ、このロ−タと共に研摩体を回転させてワ−ク表面を研削するが、この際、送気管から送られるエアを環状エア配管を通して分岐管に導き、ワ−ク表面に噴出させて研削カスを吹き払う。これによりサンディング作業と併行して、或いはほぼ同時に除塵が出来、時間と手間が節約される。又、エアの吹き付け量を流量調整弁で調整し、研削カスの発生量等に応じて最適の吹き出し量とする。 Air is sent from the air pipe to rotate the rotor, and the abrasive body is rotated together with this rotor. The surface of the workpiece is ground by grinding the surface of the workpiece. At this time, the air sent from the air pipe is It is guided through a pipe to a branch pipe and sprayed onto the work surface to blow off the grinding debris. to this Dust removal can be done in parallel with sanding work or almost simultaneously, saving time and effort. Saved. In addition, the amount of air sprayed can be adjusted with a flow rate adjustment valve to reduce the amount of grinding scum generated, etc. Optimize the amount of balloons depending on the situation.
