Description

【発明の詳細な説明】 本発明は空気調和機用エアーフィルターの製造方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing an air filter for an air conditioner.

従来の空気調和機用エアーフィルターの製造方法を第１
図と第２図により説明する。The first manufacturing method for conventional air filters for air conditioners
This will be explained with reference to the drawings and FIG.

１はエアーフィルターで、フィルタ一部材２と枠部材３
とよりなっている。1 is an air filter, which includes a filter member 2 and a frame member 3.
It is becoming more and more.

フィルタ一部材２は硬質塩化ビニル樹脂等を糸状に成形
し、それを除塵効果が良く通風抵抗を少なくするよう波
形の網に織って単位面積あたりの網の面積を大きくし、
通風面積を大きくしたものである。The filter member 2 is formed by molding hard vinyl chloride resin or the like into a thread shape, and weaving it into a corrugated mesh to increase the area of the mesh per unit area so as to have a good dust removal effect and reduce ventilation resistance.
It has a larger ventilation area.

枠部材３はＡＢＳ樹脂またはスチロール樹脂等で成形さ
れている。The frame member 3 is molded from ABS resin, styrene resin, or the like.

而して、エアフィルター１は枠部材３を成形する型（図
示せず）にフィルタ一部材２を挟んで型締めした状態で
、枠部材３を射出成形することにより製作され、フィル
タ一部材２と枠部材３とが一体に形成されている。The air filter 1 is manufactured by injection molding the frame member 3 with the filter member 2 sandwiched between a mold (not shown) for molding the frame member 3 and clamped. and the frame member 3 are integrally formed.

かかるエアーフィルター１の製造方法によれば、枠部材
３を成形するときにフィルタ一部材が樹脂の流れの障害
となるため射出成形性が非常に悪く、枠部材３の樹脂量
が少ないにもかかわらず、大きな射出成形機が必要とな
り割高となっている。According to the manufacturing method of the air filter 1, when molding the frame member 3, the filter member becomes an obstacle to the flow of the resin, resulting in very poor injection moldability, even though the amount of resin in the frame member 3 is small. First, it requires a large injection molding machine, making it relatively expensive.

しかも、枠部材２の薄肉化が非常に困難であった。Moreover, it is extremely difficult to reduce the thickness of the frame member 2.

また、型締め時、枠部材３の端面からはみ出たフィルタ
一部材２を切断するために、枠部材３を成形する型は刃
型にする必姿があり、このために型寿命が短く、型のメ
ンテナンス及び平面度の確保が困難であった。Furthermore, in order to cut off the filter member 2 that protrudes from the end face of the frame member 3 during mold clamping, the mold for forming the frame member 3 must be a blade type, which shortens the life of the mold. Maintenance and ensuring flatness were difficult.

更に、射出成形時にフィルタ一部材２を挟んで型締めし
ているので枠部材３の両側に位置する型当り部（第２図
のＡ部）は波形のフィルタ一部材２が潰れて平板状とな
り、加えてフィルタ一部材２の糸状の断面が潰れて通風
面積が激減し、通風抵抗が増大して風量減少など性能低
下の要因となるとともに、型締めが強すぎるとフィルタ
一部材２が枠部材３の端面で切れてしまうことがあり、
型締めか弱すきると型部材３の一部が流出してパリが発
生して同じくフィルタ一部材２が切れ易くなると同時に
、通風抵抗が増大する。Furthermore, since the filter member 2 is sandwiched and the mold is clamped during injection molding, the corrugated filter member 2 is crushed into a flat plate shape at the mold abutting portions located on both sides of the frame member 3 (section A in Fig. 2). In addition, the thread-like cross section of the filter member 2 is crushed, drastically reducing the ventilation area, increasing ventilation resistance and causing a decrease in performance such as a decrease in air volume.If the mold clamping is too strong, the filter member 2 becomes a frame member. It may break at the end of 3.
If the mold is not tightly clamped, a part of the mold member 3 will flow out, causing cracks, which will make the filter member 2 more likely to break, and at the same time, the ventilation resistance will increase.

従って型締めの管理及び型のメンテナンスが非常に面倒
である。Therefore, mold clamping management and mold maintenance are extremely troublesome.

また、フィルタ一部材２と枠部材３の材質が異質のもの
であるため、枠部材３の成形収縮によりフィルタ一部材
２に弛みが発生し、これを修正するために温風などによ
る矯正が必要となるとともに、不良品などの再生ができ
ない点があった。In addition, since the filter member 2 and the frame member 3 are made of different materials, the filter member 2 may become loose due to molding shrinkage of the frame member 3, and correction using hot air or the like is required to correct this. At the same time, there was a problem that defective products could not be recycled.

本発明は上記欠陥を解消するためになされたものである
。The present invention has been made to eliminate the above-mentioned defects.

則ち、ポリプロピレン樹脂等を糸状に成形したものを織
って網状に成形して通風抵抗を小さくしたフィルタ一部
材５と同材質（フィルタ一部材５がポリプロピレン樹脂
の場合は枠もポリプロピレン樹脂）で、且つ、フィルタ
一部材５の分子量より低い分子量の材料（超音波振動を
付与した場合分子量の低い方が分子間の摩擦が大きく、
発熱溶融しやすい）からなる枠部材６をフィルタ一部材
５と別に成形し、該枠部材６の成形時にフィルタ一部材
５の外周端四辺全周との溶着面の外周四辺に凸状にした
リブ６ａを一本または複数本設けるとともに、枠部材６
のフィルタ一部材５との溶着面の端面を円弧状に形成し
、これら成形後の両部材５，６を重ねて超音波を付与す
ると、枠部材６のリブ６ａが先に溶融し、次にフィルタ
一部材５の枠部材６との接触部の表面を溶融し、リブ６
ａがフィルタ一部材５の網状隙間に流れ込んで、互いに
かみ合った状態に結合されて一体となるものである。In other words, it is made of the same material as the filter member 5, which is made by weaving polypropylene resin or the like into a thread shape and forming it into a net shape to reduce ventilation resistance (if the filter member 5 is made of polypropylene resin, the frame is also made of polypropylene resin), In addition, a material with a molecular weight lower than the molecular weight of the filter member 5 (when ultrasonic vibration is applied, the lower the molecular weight, the greater the friction between molecules;
A frame member 6 consisting of a material (which easily melts due to heat generation) is molded separately from the filter member 5, and when the frame member 6 is molded, ribs are formed on the four outer circumferential sides of the welded surface with all four outer peripheral edges of the filter member 5. In addition to providing one or more frame members 6a,
The end face of the welded surface with the filter member 5 is formed into an arc shape, and when both molded members 5 and 6 are overlapped and ultrasonic waves are applied, the rib 6a of the frame member 6 melts first, and then The surface of the contact portion of the filter member 5 with the frame member 6 is melted to form ribs 6.
a flows into the mesh-like gap of the filter member 5, and are combined in a mutually interlocking state to become an integral body.

以下、本発明の詳細を第３図〜第６図に示す一実施例に
より説明する。The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 3 to 6.

４はエアーフィルターで、フィルタ一部材５と枠部材６
とよりなっている。4 is an air filter, which includes a filter member 5 and a frame member 6.
It is becoming more and more.

フィルタ一部材５はポリプロピレン樹脂等を糸状に成形
し、それを波形に織った網状の通風抵抗を良くしたもの
である。The filter member 5 is made of polypropylene resin or the like into a thread shape and woven into a corrugated net shape to improve ventilation resistance.

枠部材６は前記フィルタ一部材５と同材質のものとした
融点が同じで溶着性が良く溶着不良が生じにくく、成形
収縮率が同じでフィルタ一部材５が弛まないものである
。The frame member 6 is made of the same material as the filter member 5, has the same melting point, has good weldability, is less prone to defective welding, has the same molding shrinkage rate, and prevents the filter member 5 from loosening.

また、不良品が生じても各部材を分離する必要がなく、
加熱溶融温度も同一であるので一方の部材が必要以上に
加熱されることがなく材質の劣下が少なくなり、又、一
方が溶けていないという不都合もなく再生容易である。In addition, even if a defective product occurs, there is no need to separate each component.
Since the heating and melting temperatures are also the same, one member is not heated more than necessary, resulting in less deterioration of the material, and there is no inconvenience that one member is not melted, making it easy to recycle.

該枠部材６はフィルタ一部材５とは別に成形したもので
、射出成形時のフィルタ一部材５による樹脂の流れの抵
抗になるものが無く、従って、成形機が小型でも良く、
型も最少数でよいため装置、工具費が安価となり、さら
に高速成形および薄肉化も可能となる。The frame member 6 is molded separately from the filter member 5, and there is no resistance to the flow of resin by the filter member 5 during injection molding, so the molding machine can be small.
Since the minimum number of molds is required, equipment and tool costs are low, and high-speed molding and thinning are also possible.

また、枠部材６の分子量をフィルタ一部材５の分子量よ
り低いものを使用し、超音波振動による溶着時に分子量
の低い枠部材６が先に溶融するものとし、且つ、枠部材
６のフィルター５との溶着面の端面を円弧状に成形して
鋭角部やパリを無くして、フィルタ一部材の溶着部と該
鋭角部やパリとの接触部に超音波振動が集中し、過剰加
熱するのを防止したので、フィルタ一部材５の溶融過多
や材質の劣下による強度の低下が無く、フィルタ一部材
５が枠部材６の端面で切れることがない。Furthermore, the molecular weight of the frame member 6 is lower than that of the filter member 5, and the frame member 6 with a lower molecular weight is melted first during welding by ultrasonic vibration, and the frame member 6 and the filter 5 are melted first. The end face of the welded surface of the filter is formed into an arc shape to eliminate sharp corners and burrs, thereby preventing ultrasonic vibrations from concentrating on the contact area between the welded part of the filter member and the sharp corners and burrs, resulting in excessive heating. Therefore, there is no decrease in strength due to excessive melting of the filter member 5 or deterioration of the material, and the filter member 5 is not cut at the end face of the frame member 6.

枠部材６にはリブ６ａを有し、リブ６ａの形状は超音波
により溶けやすいように山伏に形成し、フィルター溶着
面のほぼ全周にわたって２本設けてあり、該リブ６ａが
溶融するとフィルタ一部材５の隙間へ流れ込んで、互い
にかみ合った状態に合わさり強固に結合される。The frame member 6 has ribs 6a, and the shape of the ribs 6a is shaped like a ridge so that it can be easily melted by ultrasonic waves.Two ribs are provided around the entire circumference of the filter welding surface, and when the ribs 6a melt, the filter is heated. They flow into the gaps between the members 5 and are interlocked with each other to be firmly connected.

その途中には先端を鋭角にしたフィルタ一部材５セット
時の位置決め用のピン６ｂを複数本リブ６ａより高くし
て設けである。In the middle thereof, a plurality of pins 6b with acute angle tips for positioning when five filter members are set are provided higher than the ribs 6a.

また、フィルタ一部材５の端面を枠部材６の外周端面よ
り内側にして、手が触れても傷が付かないようにしてい
る。Further, the end face of the filter member 5 is placed inside the outer circumferential end face of the frame member 6 so that it will not be damaged even if touched by hand.

７はフィルタ一部材５との接触面を平面にした溶着用ホ
ーンで、ピン６ｂとの相対位置には逃げ穴γａを設け、
逃げ穴７ａの深さＢはピン高さＣより小さくしである。7 is a welding horn whose contact surface with the filter member 5 is flat, and an escape hole γa is provided at a position relative to the pin 6b;
The depth B of the escape hole 7a is smaller than the pin height C.

８は接触面を平面にしたホーン受けである。8 is a horn receiver with a flat contact surface.

而して、フィルタ一部材５と枠部材６を一体にするには
、ホーン受け８に枠部材６のリブ６ａを設けた反対面が
ホーン受け８に接するようセットし、フィルタ一部材５
をピン６ｂに仮止め後溶着用ホーン７により超音波を与
えると、接合面の摩擦により分子量の低い方の枠部材６
に設けたリブ６ａが初めに溶融してフィルタ一部材６の
網状の隙間に流れ込み、次いでフィルタ一部材５の溶着
部の表面が溶融して枠部材６と強固に係合溶着して一体
となる。In order to integrate the filter member 5 and the frame member 6, the opposite surface of the frame member 6 on which the ribs 6a are provided is set in contact with the horn receiver 8, and the filter member 5 is
When ultrasonic waves are applied by the welding horn 7 after temporarily fixing the frame member 6 to the pin 6b, the frame member 6 with a lower molecular weight
The ribs 6a provided on the filter member 6 first melt and flow into the mesh-like gaps of the filter member 6, and then the surface of the welded portion of the filter member 5 melts and firmly engages and welds the filter member 6 to become integral. .

このとき、フィルタ一部材５の溶着部は熱とホーンの圧
力により少し潰されるが、通風部ではないので性能には
何の影響も生じない。At this time, the welded part of the filter member 5 is slightly crushed by the heat and the pressure of the horn, but since it is not a ventilation part, there is no effect on the performance.

また、フィルタ一部材５の端面は、枠部材６の外周面よ
り内側に位置せしめ、溶着用ホーン７の幅りを枠部材６
の幅Ｅより大きく配置して、溶着時にセット位置が少し
ずれても溶着不良の心配をなくしたものである。Further, the end surface of the filter member 5 is positioned inside the outer circumferential surface of the frame member 6, and the width of the welding horn 7 is set to the frame member 6.
This eliminates the risk of poor welding even if the set position shifts slightly during welding.
