Description
【０００１】[0001]
本考案は、樹脂で成形された３次元形状である樹脂成形品の一面全域に、合成樹 脂からなる樹脂繊維布を貼り付けた３次元形状複合体の製造において用いる装置 であり、詳しくは、樹脂成形品からはみ出た樹脂繊維布いわゆる耳の部分を切断 する装置に関するものである。 The present invention is an apparatus used in the manufacture of a three-dimensionally shaped composite in which a resin fiber cloth made of synthetic resin is adhered to the entire surface of a resin molded product having a three-dimensional shape formed of resin. The present invention relates to a device for cutting a so-called ear portion of a resin fiber cloth protruding from a resin molded product.

車両の内装材料として、軽量化を図るため樹脂成形品を多く用いているが、そ の樹脂成形品は、樹脂成形品の表面に意匠目的のため樹脂繊維布や、安全性確保 のためクッション性を持つ樹脂繊維布を貼り付けて樹脂成形品と樹脂繊維布との 一体複合体（以下「複合体」と称する）を車両用内装材として使用している。 また、車両用内装材は安全性や機能性を重視するため、多くの曲面を持つ３次 元的である複雑な形状であることが多い。 As a vehicle interior material, many resin molded products are used to reduce the weight.The resin molded products have a resin fiber cloth on the surface of the resin molded products for design purposes, and a cushioning property for ensuring safety. An integrated composite of a resin molded product and a resin fiber cloth (hereinafter referred to as a “composite”) is used as an interior material for vehicles. Also, vehicle interior materials often have a complicated three-dimensional shape with many curved surfaces in order to emphasize safety and functionality.
【０００３】 そのため、車両用内装材を製造する時、樹脂成形品へ樹脂繊維布を貼り付けて ある平板状の複合材を用いて所望の形状へ加工した場合、折り曲げなどの曲面加 工を施した曲面部分における樹脂繊維布が伸縮の影響でシワ等が発生し、意匠性 、クッション性、及び、耐久性損なう場合や、曲面箇所から破けてしまって不良 品を発生させる要因となる場合がある。 この様に、樹脂成形品と樹脂繊維布を貼り付けた平板状の複合材を３次元形状 に加工することは生産性低下の要因となる場合がある。 そこで、以上の様な不具合を生じさせない製造方法として、まず、射出成形等に より所望する形状へ樹脂成形品を形成した後、適当な大きさに裁断した樹脂繊維 布を接着材等により貼り付ける方法が行われようになった。[0003] Therefore, when manufacturing interior materials for vehicles, when processing into a desired shape using a flat composite material in which a resin fiber cloth is attached to a resin molded product, a curved surface processing such as bending is performed. In some cases, wrinkles may occur due to the expansion and contraction of the resin fiber cloth on the curved surface part, resulting in impaired design, cushioning, and durability, or may be broken from the curved part and cause defective products. . As described above, processing a flat composite material in which a resin molded product and a resin fiber cloth are adhered into a three-dimensional shape may cause a decrease in productivity in some cases. Therefore, as a manufacturing method that does not cause the above problems, first, a resin molded product is formed into a desired shape by injection molding or the like, and then a resin fiber cloth cut into an appropriate size is attached with an adhesive or the like. The method has begun to take place.
【０００４】 しかし、樹脂成形品の面積より広い樹脂繊維布を使用するため、樹脂成形品の 周囲端面から余ったいわゆる耳と言われる樹脂繊維布がはみ出し、この耳を除く ために裁断等の処理が必要である。 その裁断する方法としては、次のような手段が用いられて来た。 １． 人が手作業で裁断する。 ２． レーザカッターやウォタージェットカッターを用いて裁断する。 ３． トムソン刃（上下から刃を突き合わせて切断）を用いて裁断する。 しかし、前に２のレーザカッター及びウォータージェットカッターを用いる方 法においては、設備が高価になる欠点があった。 また、３のトムソン刃を用いる方法においては、樹脂繊維布の材質により切れ 残りが発生する欠点があった。 そこで、手作業でカッターやハサミを用いて耳を裁断している場合が多い。し かし、手作業のためと形状が３次元で複雑であることから裁断作業の時間がかか り生産効率向上の妨げになっていた。However, since a resin fiber cloth that is larger than the area of the resin molded article is used, the resin fiber cloth, which is a so-called “ear,” which is left over from the peripheral end surface of the resin molded article, protrudes, and processing such as cutting is performed to remove the ears. is necessary. The following means have been used as the cutting method. 1. People cut by hand. 2. Cut using a laser cutter or water jet cutter. 3. Cut using a Thomson blade (cutting the blade from the top and bottom). However, the method using the laser cutter and the water jet cutter described in 2 above has a disadvantage that the equipment is expensive. Further, the method using a Thomson blade has a disadvantage that uncut portions occur due to the material of the resin fiber cloth. Therefore, the ears are often cut by hand using a cutter or scissors. However, because of the manual work and the complicated three-dimensional shape, cutting work took a long time and hindered the improvement of production efficiency.

【００２９】 シャフトＢ５５に具備した押し当て板５４が複合体１０に貼り付けられた樹脂 繊維布１２に当接した位置で（図９）、押切刃２０の温度が設定温度３６０℃以 上に達していたら、さらに取り付け板５３が降下することによりスプリング５６ が縮み、その効果にて押し当て板５４にて複合体１０を受け台５１に押し付けて 圧接保持することができる。もし、設定温度へ達していなかったら、設定温度へ 達するまで降下を一時中断し設定温度になるのを待つ。 なお、温度最終確認を行う時の取り付け板５３の位置は、例示した位置に限定 するわけではなく、押切刃２０が樹脂繊維布１２に当接するまでの位置であれば どこでも良い。At a position where the pressing plate 54 provided on the shaft B55 is in contact with the resin fiber cloth 12 attached to the composite 10 (FIG. 9), the temperature of the pressing cutting blade 20 reaches the set temperature of 360 ° C. or more. Then, when the mounting plate 53 is further lowered, the spring 56 is contracted, and the composite plate 10 can be pressed against the receiving table 51 by the pressing plate 54 and held in pressure contact by the effect. If the temperature has not reached the set temperature, temporarily suspend the descent until the temperature reaches the set temperature and wait for the temperature to reach the set temperature. The position of the mounting plate 53 at the time of performing the final temperature check is not limited to the illustrated position, but may be any position as long as the pressing blade 20 is in contact with the resin fiber cloth 12.
【００３０】 取り付け板５３がさらに降下すると、押切刃２０が樹脂繊維布１２に当接し、当 接した部分から押切刃２０の熱で樹脂繊維布１２を溶かし耳部１５を溶断するこ とができる（図１０及び図１１参照）。押切刃２０が傾斜して取り付けてあるた め、先当たりした部分から徐々に押し切るように溶断され（図１１参照）その結 果、切り残りがなく確実に樹脂繊維布１２を一度に溶断された。When the mounting plate 53 further descends, the pushing blade 20 comes into contact with the resin fiber cloth 12, and the heat of the pushing blade 20 melts the resin fiber cloth 12 from the contacted portion, thereby cutting off the ear 15. (See FIGS. 10 and 11). Since the push-cutting blade 20 is attached at an angle, the cutting is performed so as to gradually push off from the point where it comes into contact (see FIG. 11). As a result, the resin fiber cloth 12 is cut off at once without any cutting residue. .
【００３１】 溶断中、常に温度センサー３５にて押切刃２０の温度を計測しており、設定温 度の３６０℃を越えた場合は制御回路７３からの信号にてリレー７２により通電 を遮断するが、余熱にて約３７０℃まで上昇する。その後、温度が低下し３６０ ℃より下がった場合電圧の再印加を行い発熱させる。この様に電圧の印加停止を 繰り返すことにより押切刃２０の温度をほぼ一定に保つことが可能になった。During the fusing, the temperature of the press cutting blade 20 is always measured by the temperature sensor 35. When the temperature exceeds the set temperature of 360 ° C., the power is cut off by the relay 72 by a signal from the control circuit 73. Rise to about 370 ° C. with residual heat. Thereafter, when the temperature drops below 360 ° C., a voltage is reapplied to generate heat. Thus, by repeatedly stopping the application of the voltage, the temperature of the pressing blade 20 can be kept almost constant.
【００３２】 図１２の様に取り付け板は樹脂繊維布１２の耳部１５を全て溶断する下降端ま で達した時、電圧印加を止めシリンダー５８にて取り付け板５３を上昇させ待機 位置に戻り、かつ、押切刃２０の温度が低下する。受け台５１から樹脂繊維布１ ２の耳部１５を取り除いた複合体１０を取り出せば、図１に示す自動車の内装に 用いる内装材が有られた。 なお、押切刃２０の固定部２９は体積が他の所に比べて大きくなるので、抵抗 値が低くなり温度が上昇しきれない場合があるので、固定部２９に適宜な大きさ のくいきりを形成すると均一な温度分布が得られる。As shown in FIG. 12, when the mounting plate has reached the lower end at which all of the ears 15 of the resin fiber cloth 12 are melted, the application of voltage is stopped, the mounting plate 53 is raised by the cylinder 58 and returned to the standby position. In addition, the temperature of the pressing blade 20 decreases. When the composite body 10 from which the ears 15 of the resin fiber cloth 12 were removed was taken out of the cradle 51, the interior material used for the interior of the automobile shown in FIG. 1 was obtained. Since the volume of the fixing portion 29 of the press cutting blade 20 is larger than that of other portions, the resistance value may be low and the temperature may not be able to rise completely. When formed, a uniform temperature distribution is obtained.

以上説明した様に、本考案の３次元形状複合体に用いる縁取り装置は、押切刃 を３次元形状複合体の外形輪郭と同一にしたため、発熱させながら３次元形状複 合体に押しあてると樹脂繊維布の余分な部分つまり耳部を一気に溶断することが できる。したがって、本考案の３次元形状複合体に用いる縁取り装置を用いると 次の様な効果を得ることができる。 ａ．従来作業者が手作業でカッターやハサミを用いて耳部を裁断していたが、本 装置を用いることにより３次元形状でも自動化が図れる。 ｂ．押切刃への電圧印加は溶断する時のみ印加し、待機中は印加しないことから 省エネルギーを図れるとともに、押切刃の耐久性、温度制御の信頼性向上の効果 をも得られる。 ｃ．押切刃を３次元形状複合体に対して傾斜させて押し当てるため、シャープな 溶断が得られる。 As described above, the edging device used for the three-dimensionally shaped composite of the present invention uses the same cutting contour as the outer contour of the three-dimensionally shaped composite. The excess part of the cloth, ie the ears, can be blown at a stroke. Therefore, the following effects can be obtained by using the edging device used for the three-dimensionally shaped composite of the present invention. a. Conventionally, the operator cuts the ears manually with a cutter or scissors, but by using this device, automation can be achieved even for three-dimensional shapes. b. Voltage is applied to the cutting blade only when it is blown, and is not applied during standby. This saves energy and also improves the durability of the cutting blade and the reliability of temperature control. c. Since the pressing blade is pressed against the three-dimensionally shaped composite while being inclined, sharp fusing can be obtained.
