Description
【０００１】[0001]
本案は、各種機器の清掃などに用いられるエアガンのノズル前方に配設される 空気噴射ノズルの構造に関する。 The present invention relates to a structure of an air injection nozzle arranged in front of a nozzle of an air gun used for cleaning various devices.
【０００２】[0002]
一般に、各種機器などの清掃に、圧縮機から吐出される高圧空気を用いてエア ガンにより該各機器の清掃が行なわれている。図２は、従来型式のエアガンの空 気吐出口であるノズルを示す断面図であるが、通常、圧縮機から送られる高圧空 気は、同図に見られるように、導通部３から搾られ、該導通部より径小としたノ ズル２から直接大気へと吐出される構造となっている。 Generally, for cleaning various devices, each device is cleaned with an air gun using high-pressure air discharged from a compressor. FIG. 2 is a cross-sectional view showing a nozzle which is an air discharge port of a conventional type air gun. Normally, the high pressure air sent from the compressor is squeezed from the conducting portion 3 as shown in FIG. The nozzle 2 having a diameter smaller than that of the conducting portion is directly discharged into the atmosphere.
【０００３】[0003]
然るに、敍上のような構成では、圧縮空気が直接外界（大気）へと噴出される ので、ノズル２から高圧空気が大気に排出される際、圧力が瞬時に開放されて膨 張し、連続的に大きな音を発生する、のみならず、被清掃物にあたる音も反射し 、騒音となって作業員は耳栓をするのが一般的となっている。そして、この大き な連続的音は、多量生産方式を採っている工場などでは、ラインで連続的に搬送 される機器の該ライン近傍に複数人の作業員が待機しているため、互いに騒音発 生源となり騒音公害問題となって作業効率を低下させるだけでなく、とくに、聴 覚器官、消化器官などに機能障害を起こす等、望ましくない問題が発生している のが現状と言える。 本考案は、敍上の欠点を解消せんとするするもので、その目的とするところは 、前記騒音を可及的に小として作業員の健康を保持すると共に、その作業効率を も向上せしめんとすることにある。 However, in the above-mentioned configuration, since compressed air is directly ejected to the outside (atmosphere), when the high-pressure air is discharged from the nozzle 2 to the atmosphere, the pressure is instantly released and expanded, resulting in continuous expansion. Not only does it generate a loud noise, but also the sound that hits the object to be cleaned is reflected, and it is common for workers to put earplugs on it. In a factory that employs a high-volume production system, this large continuous noise is generated by noises generated by multiple workers waiting near the line of equipment that is continuously conveyed on the line. The current situation is that not only is it a source of noise and a problem of noise pollution, which reduces work efficiency, but it also causes undesirable problems such as functional impairment of the hearing and digestive organs. The present invention is intended to solve the drawbacks of the strength. The purpose of the present invention is to reduce the noise as much as possible to maintain the health of workers and improve the work efficiency. To do so.

本考案は、エアガン本体１のノズル２と一体又は該ノズルと別体に形成されて なり、前記ノズルより吐出口８に向けて順次径大とする複数個の段差を備える複 数個の通気口５の穿孔された合成樹脂又はゴム状弾性体よりなる内筒４と、該内 筒の外周側には吸音材６が囲繞されて前記ノズルの前方に形成された吸音部７に 装着された構成としている点に特徴を有する。 The present invention comprises a plurality of vent holes which are formed integrally with the nozzle 2 of the air gun body 1 or formed separately from the nozzle, and which are provided with a plurality of steps having a diameter gradually increasing from the nozzle toward the discharge port 8. 5, an inner cylinder 4 made of a perforated synthetic resin or a rubber-like elastic body, and a sound absorbing material 6 surrounding the inner cylinder and attached to a sound absorbing portion 7 formed in front of the nozzle. It has a feature in that.

図１は、本考案の一実施例を示す側面図で、従来型式のものと同一箇所には同 一符号を付け、本考案の異なる点について詳述すると、４は、例えば、対磨耗性 のあるポリスチレンやＡＢＳ樹脂などからなる合成樹脂又はゴム状弾性体から造 られていて、吐出口７に向けて階段的に段差が形成された径大とされた吸収筒で 、実験に徴するに、例えば、ａ部位はノズル２の径の略２倍、ｂ部位はａ部位の 略１．５倍、ｃ部位はｂ部位の略１．５倍、の径に夫々定めるのが望ましい。 ５は、前記吸収筒４のａ，ｂ，ｃ，各部位の外周および長手方向に夫々適宜間 隔で穿孔された複数個の通気口、６は、前記吸収筒４の外周壁と後記する本体１ に形成された吸音部との間に装填される例えば金属または合成樹脂を細い糸状と したスチールウールまたは樹脂毛などからなる吸音材で、吸音筒４の外周壁を取 囲むよう同図々示のように吸音部７に装着されている。 なお、以上述べた消音機構は、図１に示すよう、エアガン本体１に一体成型し ても、同図ｘ−ｘ線部位で既存のエアガン本体に着脱自在に取付け可能に、別体 として構成してもよい。 FIG. 1 is a side view showing an embodiment of the present invention. The same parts as those of the conventional type are designated by the same reference numerals, and different points of the present invention will be described in detail. An absorption cylinder made of a synthetic resin or rubber-like elastic material such as polystyrene or ABS resin and having a large stepped step toward the discharge port 7. It is preferable that the diameter of the a portion is approximately twice the diameter of the nozzle 2, the diameter of the b portion is approximately 1.5 times the diameter of the a portion, and the diameter of the c portion is approximately 1.5 times the diameter of the b portion. Reference numeral 5 denotes a plurality of vent holes perforated at appropriate intervals in the outer circumference and the longitudinal direction of a, b and c of each part of the absorption cylinder 4, and 6 denotes an outer peripheral wall of the absorption cylinder 4 and a main body described later. The sound absorbing member is made of, for example, steel wool or resin bristles in the form of thin thread made of metal or synthetic resin, and is inserted between the sound absorbing portion formed in 1 and the sound absorbing cylinder 4 so as to surround the outer peripheral wall of the sound absorbing cylinder 4. As shown in FIG. The muffling mechanism described above is configured as a separate body so that it can be detachably attached to the existing air gun body at the line xx in the figure even if it is integrally molded with the air gun body 1 as shown in FIG. You may.

本考案は、敍上の構成よりなり、次いで、構成に基づく作用効果について詳述 すると、エアガン本体１のノズル２から放射された圧縮空気は、先ず、該ノズル より径大とされた吸収筒４のａ部位に放出されるので、当該部位での空気流量の 減衰を避け乍ら該吸収筒の周壁に穿孔された複数個の通気口５へと放出されて、 さらに多孔質吸音材である繊維からなる吸音材６へと侵出してゆき、発生騒音中 の高周波分（音響エネルギーである２，５００［Ｈｚ］以上の周波数帯域）が初 段階で吸収されるため、しかも、吸音筒４のｂ部位、ｃ部位において既述のａ部 位と同じ作用が繰返されるので、吐出口８から放出された圧縮空気は、有害な前 記音響エネルギーを殆ど失い、即ち、３段なる複数段の段差により空気流量に対 する抵抗を少なくして該流量の減衰を防ぐため、作業員は、全く耳栓を着用する 必要も無くなり、静かな環境で連続的に作業が継続でき、従来型式のもので生じ たような生理的機能障害を起こすこともなく、作業効率も向上する等、簡単な構 成ながらも本案所期の目的を充分達成し得る優れた効果が期待できる。 The present invention has a ridge structure. Next, the operation and effect based on the structure will be described in detail. First, the compressed air emitted from the nozzle 2 of the air gun body 1 is first absorbed by the absorption cylinder 4 having a diameter larger than that of the nozzle. Since it is released to the part a, the air flow rate is avoided to be attenuated in the part and is released to the plurality of ventilation holes 5 perforated in the peripheral wall of the absorption cylinder, and the fiber is a porous sound absorbing material. The sound absorbing material 6 consisting of the sound absorbing material 4 is absorbed into the sound absorbing material 6 and the high frequency component (frequency band of 2,500 [Hz] or more of acoustic energy) in the generated noise is absorbed at the initial stage. Since the same action as the above-mentioned a part is repeated in the parts and c parts, the compressed air discharged from the discharge port 8 loses most of the harmful acoustic energy described above, that is, due to the steps of three steps. Low resistance to air flow In order to prevent the flow rate from decaying, the worker does not have to wear earplugs at all, can continue to work in a quiet environment, and has the physiological dysfunction that occurs in the conventional type. It is possible to expect an excellent effect that it can achieve the intended purpose of this plan sufficiently even though it has a simple structure, such as not causing it and improving work efficiency.
