回転刃による孔穿けは、穿孔治具を突き刺して行う孔穿けに比べ、孔周縁が窪んだり突出することのないきれいな孔穿けが行われ、形状安定性に優れる利点があるが、図５に示すように切片５ａの一部が孔縁に繋がったまま残ることがあり、こうした不完全な穿孔が行われ、切片５ａがエア抜き孔を塞ぐようになると、エアの排出が妨げられ、ドア閉じ性に悪影響を及ぼすようになる。中空シール部の場合、穿孔時に切片が繋がったまま残っても目視による確認が容易であり、取り除くのも容易であるが、図５に示すように切片５ａが中空シール部内の支柱に残った場合、目視による確認が困難で、その取除きも容易でない。こうした問題は、前述するオープニングウェザストリップのみならず、中空シール部及び支柱を備えた他のウェザストリップにおいても中空シール部及び支柱へ穿孔する際に同様に生ずる。   Compared with the hole drilling performed by piercing the drilling jig, the hole drilling with the rotary blade is a beautiful hole drilling without causing the hole periphery to be recessed or protruding, and has an advantage of excellent shape stability. In this way, a part of the section 5a may remain connected to the edge of the hole, and when such incomplete drilling is performed and the section 5a closes the air vent hole, the discharge of air is hindered and the door closing property Will have a negative effect. In the case of the hollow seal portion, even if the section remains connected at the time of drilling, it is easy to visually confirm and remove, but when the section 5a remains on the support in the hollow seal portion as shown in FIG. It is difficult to confirm visually and its removal is not easy. Such a problem occurs not only in the above-described opening weather strip but also in other weather strips having a hollow seal portion and a support column when drilling into the hollow seal portion and the support column.

本発明は、上記のような問題を生ずることがないウェザストリップの中空シール部への穿孔方法及び装置を提供することを目的とする。   An object of the present invention is to provide a method and apparatus for drilling a hollow seal portion of a weather strip that does not cause the above-described problems.

請求項１に係る発明は、自動車の車体開口部を開閉する開閉部材と、前記車体開口部周縁との間をシールする中空シール部を備え、中空シール部内に支柱を設けたウェザストリップにおける前記中空シール部への穿孔方法であって、前記ウェザストリップを押出す押出し装置の口金の吐出側に中空シール部の内側を形成するコア金型より突出する穿孔治具を進退可能に設け、該穿孔治具を口金より押出されたウェザストリップの支柱に対し突き刺して孔穿けを行い、かつ同時に或いはその後に中空シール部に対し外側から回転刃による孔穿けを行うこと特徴とする。   According to a first aspect of the present invention, the hollow in the weather strip is provided with an opening / closing member that opens and closes a vehicle body opening of a vehicle and a hollow seal portion that seals between the periphery of the vehicle body opening, and a column is provided in the hollow seal portion. A method for drilling a seal portion, wherein a drilling jig protruding from a core mold forming an inner side of a hollow seal portion is provided on the discharge side of a die of an extrusion apparatus for extruding the weather strip so as to be able to advance and retract. The tool is pierced with a support of a weather strip extruded from a base, and a hole is made, and at the same time or after that, a hole is made with a rotary blade from the outside to the hollow seal portion.

請求項２に係る発明は、請求項１に係る発明を実施する装置に関するもので、穿孔治具がワイヤー状で、口金内にＵ字形に組み込まれてスライド可能であり、その一端が前記コア金型の吐出側より突出すると共に、他端がウェザストリップ外側の口金の吐出側に突出し、またウェザストリップ外側の口金の吐出側には、前記穿孔治具の他端に連結され、該穿孔治具の一端を前記支柱に向かって進退させる作動装置が設けられることを特徴とし、
請求項３に係る発明は、請求項１に係る発明を実施する別の装置に関するもので、穿孔治具がワイヤー状であり、コア金型内に押出方向に組み込まれてスライド可能であり、その一端が前記コア金型の吐出側より突出すると共に、他端がコア金型の吸込側より突出し、また口金に連結されるヘッド又はその後方には、前記穿孔治具の他端に連結され、該穿孔治具を前記支柱に向かって進退させる作動装置が設けられることを特徴とする。 The invention according to claim 2 relates to an apparatus for carrying out the invention according to claim 1, wherein the drilling jig is wire-shaped and is slidable by being incorporated in a U-shape in the base, one end of which is the core metal The other end protrudes from the discharge side of the die outside the weather strip, and the other end of the die outside the weather strip is connected to the other end of the punch jig. Characterized in that an actuating device is provided for advancing and retracting one end of the
The invention according to claim 3 relates to another apparatus for carrying out the invention according to claim 1, wherein the drilling jig is wire-shaped and is slidable by being incorporated in the core mold in the extrusion direction. One end protrudes from the discharge side of the core mold, the other end protrudes from the suction side of the core mold, and is connected to the other end of the drilling jig at the head or the back thereof connected to the base, An actuating device is provided for advancing and retracting the drilling jig toward the support column.

請求項１に係る発明によると、中空シール部を有し、中空シール部内に支柱を設けたウェザストリップの前記支柱へのエア抜き孔の穿孔が穿孔治具を突き刺すことによって行われ、穿孔が短時間で確実に行えること、そして穿孔が確実に行えることにより穿孔箇所に手入れせねばならないような後処理を不要にできるほか、エアの抜け道が確保されるため良好なドア閉じ性を確保できること、穿孔によって孔周縁が窪んだり、突出しても中空シール部内の支柱は外部から見えないため外観が損なわれることがないこと、外部から目に付く中空シール部への穿孔は回転刃による穿孔によって行われるため外観を損なうことがなく形状が安定し、仮に切片の一部が繋がって残る不完全な穿孔が行われるようなことがあったとしても目視による確認が容易にでき、取り除きも容易にできること等の効果を奏する。   According to the first aspect of the present invention, the punching of the air vent hole to the column of the weather strip having the hollow seal portion and the column provided in the hollow seal portion is performed by piercing the punching jig, and the drilling is short. Being able to do it reliably in time and making it possible to puncture can eliminate the need for post-processing that must be maintained at the puncture site, as well as ensure a good door closing property by ensuring air passage. Even if the hole periphery is depressed or protrudes, the support in the hollow seal part is not visible from the outside, so that the appearance is not impaired, and the hollow seal part that is visible from the outside is drilled by a rotary blade Even if there is a case where incomplete perforation is left, the shape is stable without impairing the appearance, and a part of the sections are connected. Easily it can be an effect such that it is also easily removed.

また請求項２及び３記載の発明の装置を用いることにより、中空シール部内の支柱への穿孔を行うことができる。   Further, by using the apparatus according to the second and third aspects of the present invention, it is possible to perforate the support in the hollow seal portion.

以下、本発明の実施形態について図面により説明する。図中、図１〜図４に示すウェザストリップ６と同一構造部分には同一符号を付して、その説明を省略する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, the same components as those of the weather strip 6 shown in FIGS.

図６は、ウェザストリップ製造装置の全体構成を示すもので、先端に口金１１を取付けたヘッド１２には、トリム部３用の押出機１３と、中空シール部４用の押出機１４が連結され、押出機の口金１１より押出されたウェザストリップ６は、該ウェザストリップ６がＥＰＤＭ等のゴム製である場合の加硫炉又はウェザストリップ６が熱可塑性エラストマーＴＰＥ製である場合の冷却槽１５に通されて加硫又は冷却されたのち、引取機１６により引取られるようになっている。   FIG. 6 shows the overall structure of the weather strip manufacturing apparatus. An extruder 13 for the trim part 3 and an extruder 14 for the hollow seal part 4 are connected to a head 12 having a base 11 attached to the tip. The weather strip 6 extruded from the die 11 of the extruder is used as a vulcanizing furnace when the weather strip 6 is made of rubber such as EPDM or as a cooling tank 15 when the weather strip 6 is made of a thermoplastic elastomer TPE. After being passed, vulcanized or cooled, it is taken up by the take-up machine 16.

図７は、口金１１を取付けた押出機のヘッド１２の詳細を示すものであり、図８はウェザストリップ６押出し直後の口金１１の吐出側、図９は同ウェザストリップ６を示すもので、口金１１内にはＵ字管１８が埋設して組み込まれ、Ｕ字管１８の一端は、口金１１のコア金型１９より突出してＬ字形に屈折し、他端は押出されるウェザストリップ６外側の口金１１の吐出側より突出している。   7 shows details of the head 12 of the extruder to which the base 11 is attached, FIG. 8 shows the discharge side of the base 11 immediately after the weather strip 6 is extruded, and FIG. 9 shows the weather strip 6. 11, a U-shaped tube 18 is embedded and incorporated. One end of the U-shaped tube 18 protrudes from the core mold 19 of the base 11 and refracts into an L shape, and the other end is outside the weather strip 6 to be extruded. It protrudes from the discharge side of the base 11.

口金１１の吐出側にはまた、口金１１より押出されたウェザストリップ６外側に作動装置２１が取付けられ、該作動装置２１には前記Ｕ字管１８にスライド可能に通したワイヤー状の穿孔治具２２が連結され、該治具２２をＵ字管１８を通して進退させ、その一端をＵ字管１８の一端より押出し方向と直交する方向に出入りさせてウェザストリップ６の中空シール部内の支柱５に突き刺し、エア抜き孔の穿孔を行えるようにしてある。   On the discharge side of the base 11, an operating device 21 is attached to the outside of the weather strip 6 extruded from the base 11, and a wire-like drilling jig is slidably passed through the U-shaped pipe 18. 22 is connected, the jig 22 is advanced and retracted through the U-shaped tube 18, and one end of the jig 22 is made to enter and exit from the one end of the U-shaped tube 18 in a direction perpendicular to the pushing direction, and is inserted into the column 5 in the hollow seal portion of the weather strip 6. The air vent hole can be drilled.

なお、図６には図示していないが、加硫炉又は冷却槽１５と引取機１６との間に図４に示す回転刃８を進退可能に備えたエア抜き孔の穿孔装置が配置されている。   Although not shown in FIG. 6, an air vent hole punching device provided with the rotary blade 8 shown in FIG. 4 so as to be able to advance and retract is disposed between the vulcanizing furnace or cooling tank 15 and the take-up machine 16. Yes.

本装置は以上のように構成され、口金１１より押出された直後のウェザストリップ６に対しては、押出し方向と直交する方向に進退するワイヤー状の穿孔治具２２が中空シール部内の支柱５に突き刺して穿孔を行い（図７）、穿孔後は支柱と干渉しない位置に後退する。こうした穿孔加工が一定時間ごとに行われ、支柱５の長手方向に穿孔が一定間隔で形成される。支柱５に穿孔されたウェザストリップ６は、その材質によって加硫炉又は冷却槽１４に通され、加硫又は冷却されたのち、穿孔装置の回転刃８（図４参照）により中空シール部４への穿孔が行われ、ついで引取機１４により引取られる。   The present apparatus is configured as described above. For the weather strip 6 immediately after being extruded from the base 11, a wire-like drilling jig 22 that advances and retreats in a direction orthogonal to the extrusion direction is provided on the column 5 in the hollow seal portion. Puncture is performed by piercing (FIG. 7), and after the perforation, it moves backward to a position where it does not interfere with the support column. Such a drilling process is performed at regular intervals, and drillings are formed at regular intervals in the longitudinal direction of the column 5. The weather strip 6 drilled in the support 5 is passed through a vulcanizing furnace or a cooling bath 14 depending on the material, vulcanized or cooled, and then turned to the hollow seal portion 4 by the rotary blade 8 (see FIG. 4) of the drilling device. Are drilled and then taken up by the take-up machine 14.

以上のような支柱５及び中空シール部４への穿孔によりエアの抜け道が確保される。
図１０に示すウェザストリップの製造装置では、口金吐出側に突出する部分を前記Ｕ字管１８と同様、Ｌ字状に屈折した図示しない管が口金１１のコア金型１９及びヘッド１２の押出し方向に通してあり、作動装置２１がヘッド後方に設けられて、前記管にスライド可能に通したワイヤー状の穿孔治具２２に連結され、前記実施形態と同様、該治具先端を管端より出入りさせて中空シール部内の支柱５へのエア抜き孔の穿孔を行えるようにしてある。このように、作動装置２１を押出方向の直線上でヘッド後方に配置させることで作動装置自体を押出方向に進退可能とし、穿孔時に作動装置２１を押出方向に押出速度と同一速度で進退させることにより穿孔治具２２によるウェザストリップの押出方向への干渉（引っかかり等）を排除し、穿孔治具２２と同一断面の孔あけを行うことができる。 The air passage is ensured by the perforations in the support column 5 and the hollow seal portion 4 as described above.
In the weather strip manufacturing apparatus shown in FIG. 10, a tube (not shown) that is refracted into an L-shape at the portion protruding toward the die discharge side is the same as the U-shaped tube 18. The actuator 21 is provided behind the head and is connected to a wire-like drilling jig 22 that is slidably passed through the pipe. Like the embodiment, the tip of the jig enters and exits from the pipe end. In this way, the air vent hole can be drilled into the support column 5 in the hollow seal portion. In this way, by disposing the actuator 21 behind the head on the straight line in the extrusion direction, the actuator itself can be advanced and retracted in the extrusion direction, and the actuator 21 can be advanced and retracted in the extrusion direction at the same speed as the extrusion speed during drilling. Accordingly, interference (such as catching) of the weather strip in the extrusion direction by the drilling jig 22 can be eliminated, and drilling of the same cross section as the drilling jig 22 can be performed.

前記実施形態において、支柱５への穿孔は、穿孔治具２２を支柱５に突き刺して行われるが、突き刺しによる穿孔は回転刃８による回し切りに比べ穿孔時間が短くてすみ、穿孔も確実に行える。なお、穿孔加工時に穿孔の周縁が突き刺さる方向に突出するが、支柱５は外部から見えないため、これにより外観が損なわれることはない。   In the above-described embodiment, the drilling of the support column 5 is performed by inserting the drilling jig 22 into the support column 5. However, the drilling by the stab can be performed in a shorter time than the rotation by the rotary blade 8, and the drilling can be performed reliably. . In addition, although it protrudes in the direction in which the periphery of a piercing pierces at the time of a piercing process, since the support | pillar 5 is not visible from the outside, this does not impair the appearance.

中空シール部４へのエア抜き孔の穿孔は、回転刃８によってきれいに行われ、外観が損なわれることがない。この場合、仮に切片の一部が繋がって残る不完全な穿孔が行われるようなことがあっても、切片の取り除きは容易であり、切片の有無の点検も容易である。   The air vent hole is perforated in the hollow seal portion 4 by the rotary blade 8 and the appearance is not impaired. In this case, even if an incomplete perforation that remains with a part of the sections connected is performed, the sections can be easily removed and the presence or absence of the sections can be easily checked.

図示する実施形態は、ウェザストリップがオープニングウェザストリップを示すが、中空シール部内に支柱を備えた他のウェザストリップについても中空シール部への穿孔を同様にして行うことができる。   In the illustrated embodiment, the weatherstrip shows an opening weatherstrip, but other weatherstrips with struts in the hollow seal can be similarly drilled into the hollow seal.
