Description

本発明は吸塵研磨具と共に用いる集塵装置に関する。   The present invention relates to a dust collector used together with a dust-absorbing polishing tool.

自動車車体補修ショップにおいては、塗膜、パテ、プライマ等を研磨するためにほこりっぽい環境になる。研磨カスによるほこりは健康上問題となりうる。更に、ほこりは、塗装作業中にブツが発生する原因となっている。車体補修作業場に浮遊している研磨カスを少なくするために、研磨作業時には、通常集塵装置が使用される。   In car body repair shops, it becomes a dusty environment for polishing coatings, putty, primers, and the like. Dust from abrasive debris can be a health problem. Furthermore, dust is a cause of scumming during the painting operation. In order to reduce polishing residue floating in the vehicle body repair work place, a dust collector is usually used during the polishing operation.

図１は一般的な研磨／集塵装置の構成を示した模式図である。この研磨／集塵装置は吸塵研磨具１、ダストホース２、アスピレータ３、送気ホース４、及び通気性を有する集塵袋５から構成されている。送気ホース４に送気すると気流はアスピレータ３の送気口６から排気口７に送られ、その結果、吸気口８には負圧が発生する。この負圧の作用によってダストホース２を通じて吸塵研磨具１の吸塵用穴から吸気が行われる。   FIG. 1 is a schematic view showing a configuration of a general polishing / dust collecting apparatus. This polishing / dust collecting apparatus includes a dust-absorbing polishing tool 1, a dust hose 2, an aspirator 3, an air supply hose 4, and a dust collecting bag 5 having air permeability. When air is supplied to the air supply hose 4, the airflow is sent from the air supply port 6 of the aspirator 3 to the exhaust port 7, and as a result, negative pressure is generated at the intake port 8. By the action of this negative pressure, air is sucked from the dust suction hole of the dust suction polishing tool 1 through the dust hose 2.

研磨作業時には、吸塵研磨具１の研磨面に研磨シート９が装着され、研磨カスが生成する。生成した研磨カスは、吸塵用穴からの吸気と共にダストホース２及びアスピレータ３を通過し、集塵袋５内に収納される。   During the polishing operation, the polishing sheet 9 is mounted on the polishing surface of the dust-absorbing polishing tool 1 to generate polishing residue. The generated polishing residue passes through the dust hose 2 and the aspirator 3 together with the intake air from the dust suction hole, and is stored in the dust collection bag 5.

従来の研磨／集塵装置は騒音が大きく、劣悪な作業環境を作り出している。又、集塵袋は剥き出しのまま床に置かれた状態で使用される。このためしばしば袋が破れて研磨カスが集塵袋をすり抜けることがある。さらに水を使用した研磨作業の後では、床がぬれており集塵袋の網目が水により目詰まり状態となることがある。   Conventional polishing / dust collectors are noisy and create a poor working environment. Also, the dust bag is used in a state where it is placed on the floor without being exposed. For this reason, the bag is often torn and the polishing residue may pass through the dust collecting bag. Further, after the polishing operation using water, the floor is wet and the mesh of the dust bag may be clogged with water.

本発明は上記従来の問題を解決するものであり、その目的とするところは、騒音が小さく、研磨作業中集塵袋が傷み難い集塵装置を提供することにある。   The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a dust collecting device that is low in noise and hardly damages the dust collecting bag during the polishing operation.

本発明は、吸気穴及び排気穴を備えた外装箱と；
排気口が外装箱の内部に位置し、送気口及び吸気口が外装箱の外部に位置するように外装箱の吸気穴に取り付けられたアスピレータと；
外装箱内部に設置され、アスピレータからの気流が内部に導入されるようにアスピレータの排気口に取り付けられた集塵袋と；
を有する、吸塵研磨具用集塵装置を提供するものであり、そのことにより上記目的が達成される。 The present invention includes an exterior box having an intake hole and an exhaust hole;
An aspirator attached to the air intake hole of the outer box so that the exhaust port is located inside the outer box and the air supply port and the air inlet are located outside the outer box;
A dust bag installed in the exterior box and attached to the exhaust port of the aspirator so that the airflow from the aspirator is introduced into the interior;
A dust collector for a dust-absorbing polishing tool is provided, and the above object is achieved thereby.

本発明の吸塵研磨具用集塵装置は騒音が小さく、研磨作業中集塵袋が傷み難い。また、不使用時には外装箱内に研磨具、ダストホースなどを収納することができ、研磨用具の保管及び運搬に便利である。   The dust collector for a dust-absorbing polishing tool of the present invention has low noise, and the dust bag is hard to be damaged during polishing work. Further, when not in use, a polishing tool, a dust hose and the like can be stored in the outer box, which is convenient for storing and transporting the polishing tool.

図２は本発明の吸塵研磨具用集塵装置の一態様を示す模式図である。この吸塵研磨具用集塵装置は外装箱２１、アスピレータ２２及び集塵袋２３を有している。外装箱２１はプラスチック、金属のような、耐水性で、ある程度硬く衝撃に強い材料で構成される。外装箱２１は吸気穴２４及び排気穴２５を備えている。吸気穴２４にはアスピレータ２２が固定されている。アスピレータ２２の排気口２６は外装箱の内部に位置し、送気口２７及び吸気口２８は外装箱の外部に位置している。   FIG. 2 is a schematic view showing an embodiment of the dust collecting device for a dust-absorbing polishing tool of the present invention. This dust collector for dust-absorbing polishing tool has an outer box 21, an aspirator 22, and a dust bag 23. The outer box 21 is made of a water-resistant material such as plastic or metal that is hard to some extent and strong against impact. The outer box 21 includes an intake hole 24 and an exhaust hole 25. An aspirator 22 is fixed to the intake hole 24. The exhaust port 26 of the aspirator 22 is located inside the exterior box, and the air supply port 27 and the intake port 28 are located outside the exterior box.

集塵袋２３は通気性を有するが研磨カスを通さないシート状材料を袋状に形成したものである。そのようなシート材料は、布、紙などを用いて製造することができる。集塵袋２３は、アスピレータからの気流が内部に導入されるようにアスピレータの排気口２６に取付けられる。集塵袋は、アスピレータの排気口にその口を被せて周囲をクランプなどで固定してよい。ただし、取り付ける方法は特に限定されない。   The dust collection bag 23 is formed by forming a sheet-like material that has air permeability but does not allow polishing debris into a bag shape. Such a sheet material can be manufactured using cloth, paper or the like. The dust bag 23 is attached to the exhaust port 26 of the aspirator so that the airflow from the aspirator is introduced inside. The dust bag may be covered with an exhaust port of the aspirator and fixed with a clamp or the like. However, the attachment method is not particularly limited.

この吸塵研磨具用集塵装置を使用する際には、外装箱の蓋は閉じられ、蓋は不意に開かないように固定される。そして、アスピレータの吸気口２８にダストホース及び吸塵研磨具が接続される。研磨を行いながらアスピレータの送気口２７に空気が供給される。気流はアスピレータの排気口２６に送られ、アスピレータの吸気口２８が吸い込む研磨カスと一緒になって集塵袋２３内に導入される。集塵袋２３はフィルターとして機能し、研磨カスを内部に保持しながら空気を通過させる。集塵袋を通過した空気は外装箱の排気穴２５を通って外部へ出る。   When using this dust collector for dust-absorbing polishing tool, the cover of the outer box is closed and the cover is fixed so as not to open unexpectedly. A dust hose and a dust-absorbing polishing tool are connected to the intake port 28 of the aspirator. Air is supplied to the air supply port 27 of the aspirator while polishing. The airflow is sent to the exhaust port 26 of the aspirator, and is introduced into the dust bag 23 together with the polishing residue sucked by the intake port 28 of the aspirator. The dust bag 23 functions as a filter and allows air to pass through while holding the polishing residue inside. The air that has passed through the dust bag exits through the exhaust hole 25 of the outer box.

この吸塵研磨具用集塵装置ではアスピレータの排気口２６が外装箱２１内に閉じ込められるため、従来の集塵装置と比較して稼動時の騒音がかなり小さくなる。   In the dust collector for a dust-absorbing polishing tool, the exhaust port 26 of the aspirator is confined in the outer box 21, so that noise during operation is considerably smaller than that of a conventional dust collector.

騒音をより抑制するために、外装箱には消音部材を設けてもよい。図３は、消音部材を有する外装箱の一態様を示す模式図である（アスピレータ及び集塵袋は非表示）。   In order to further suppress noise, a silencer member may be provided in the outer box. FIG. 3 is a schematic view showing an aspect of the outer box having a sound deadening member (the aspirator and the dust bag are not shown).

消音部材の一例は、外装箱内に、集塵袋を取り囲むように設置された吸音材３１の層である。好ましい吸音材はメルトブローン法によって作られた繊維径１〜４マイクロメートルのマイクロファイバーと繊維径２０〜３０マイクロメートルの短繊維からなる不織布である。不織布の目付量は２００〜４００ｇ／ｍ２、厚さは４０ｍｍ以下、好ましくは１０〜３０ｍｍ程度であればよい。かかる不織布は、例えば、住友スリーエム社から商品名「Ｔｈｉｎｓｕｌａｔｅ」として市販されている。 An example of the sound deadening member is a layer of the sound absorbing material 31 installed in the outer box so as to surround the dust collection bag. A preferred sound-absorbing material is a non-woven fabric made of melt-blown microfibers having a fiber diameter of 1 to 4 micrometers and short fibers having a fiber diameter of 20 to 30 micrometers. The basis weight of the nonwoven fabric is 200 to 400 g / m 2 , and the thickness is 40 mm or less, preferably about 10 to 30 mm. Such a nonwoven fabric is commercially available, for example, from Sumitomo 3M as the trade name “Thinsulate”.

消音部材の他の例は、外装箱の排気穴に取り付けられたサイレンサー３２である。サイレンサーは市販されているものを使用すればよい。   Another example of the sound deadening member is a silencer 32 attached to the exhaust hole of the outer box. A commercially available silencer may be used.

運搬を容易にするために、外装箱には運搬補助手段を設けてもよい。図４は、運搬補助手段を有する外装箱の一態様を示す模式図である。運搬補助手段としては取っ手４１又はキャスター４２等がある。   In order to facilitate transportation, the outer box may be provided with transportation assisting means. FIG. 4 is a schematic view showing an embodiment of an outer box having a conveyance assisting means. Examples of the conveyance assist means include a handle 41 or a caster 42.
