Description

本発明はヘッドレスト、アームレストなどの自動車用シートに設ける表皮一体発泡品の製造装置に関する。     The present invention relates to an apparatus for manufacturing a foam integrated with a skin provided on an automobile seat such as a headrest or an armrest.

多数の所定形状に裁断したトリムカバー片を接ぎ合わせてヘッドレストの外形形状に袋状に縫製したトリムカバーは、縫い代が内側になるように裏返して、その裏返し用などの開口部より内部にステーを装入した後、開口部を閉口し、パッド発泡用の発泡液を内部に注入してトリムカバー、ステーにパッドを成形型で一体発泡成形している。     A trim cover that has been trimmed into a bag shape to the outer shape of the headrest by joining a large number of trim cover pieces cut into a predetermined shape, turn it over so that the seam allowance is on the inside, and place the stay inside the opening for turning it over. After the insertion, the opening is closed, and a foaming liquid for pad foaming is injected into the trim cover and the pad, and the pad is integrally foam-molded with a molding die.

そして、前記開口部からの発泡液の漏出を防止するために種々の手段を設けたものが開示されている。     And what provided various means in order to prevent the leakage of the foaming liquid from the said opening part is disclosed.

例えば、本願出願人の出願に係る特開平９−１１２５２号公報に示すように、発泡液注入時における開口部を閉口する手段がある。     For example, as disclosed in Japanese Patent Application Laid-Open No. 9-111252 related to the application of the present applicant, there is means for closing the opening at the time of injecting the foaming liquid.

特開平９−１１２５２号公報JP-A-9-111252

以上の従来装置によれば、開口部にプレート状の閉口部材に挿し込むことによって、開口部の両端部を各々外方に引っ張ることにより、開口部を閉口してトリムカバー内に注入した発泡液が開口部より漏出することがないようにしている。   According to the above conventional apparatus, the foamed liquid injected into the trim cover by closing the opening by inserting the plate-like closing member into the opening and pulling both ends of the opening outward. Is prevented from leaking from the opening.

ところが、前記閉口部材は可動型と固定型とから構成する成形型の可動型側に固定されているため、成形型に対する位置決めなどは正確であるが、成形型の固定型側にセットしたトリムカバーの開口部に閉口部材を挿入する際、可動型を固定型に閉じる寸前に行われるので、閉口部材が確実に挿入されているか否か、確認し難い。     However, since the closing member is fixed to the movable mold side of the molding die composed of the movable die and the fixed die, the positioning with respect to the molding die is accurate, but the trim cover set on the fixed die side of the molding die When the closing member is inserted into the opening, the movable mold is performed just before the movable mold is closed to the fixed mold. Therefore, it is difficult to confirm whether or not the closing member is securely inserted.

また、パッドを発泡成形後の脱型時に、閉口部材が開口部内に挿し込まれ分離し難いため、閉口部材付の可動型が固定型より取り外し難い。     In addition, when the pad is removed after foam molding, the closing member is inserted into the opening and is difficult to separate, so the movable die with the closing member is harder to remove than the fixed die.

そこで、本発明は斯様な従来品の不具合を解消することを目的とする。      Therefore, an object of the present invention is to eliminate such problems of conventional products.

以上の目的を達成するための本発明は袋状に縫製したトリムカバーを成形型にセットして、そのトリムカバー内にパッド発泡成形用の発泡液を注入して製造する表皮一体発泡品の製造装置において、
前記成形型が固定型，可動型からなり、前記トリムカバーから外部に突出したステーを収容するステー挿通溝が、当該成形型の固定型、可動型の接合箇所に設けられるとともに、
該成形型内にセットしたトリムカバーの開口部に差し込まれる閉口プレーが
該成形型の可動型で、固定型との接合面に回転自在に設けられたことを特徴とする構成である。 In order to achieve the above object, the present invention manufactures an integrated skin foam product in which a trim cover sewed in a bag shape is set in a mold and a foaming liquid for pad foam molding is injected into the trim cover. In the device
The mold comprises a fixed mold and a movable mold, and a stay insertion groove that accommodates a stay protruding to the outside from the trim cover is provided at a joint of the mold and the movable mold.
The closed play inserted into the opening of the trim cover set in the mold is
The movable mold of the mold is configured to be rotatably provided on the joint surface with the fixed mold .

そして、前記閉口プレートは成形型の固定型側に設けた開口部の幅を略同一の一枚状のプレート又は各外側の端縁間の幅が前記開口部の幅と同一の離間させて配設した一対のプレート片である。     The closing plate is arranged so that the width of the opening provided on the fixed mold side of the mold is substantially the same sheet or the width between the outer edges is the same as the width of the opening. It is a pair of plate pieces provided.

本請求項１の発明によれば、閉口プレートが成形型に回転自在に設けたので、成形型内にセットしたトリムカバーの開口部に閉口プレートが挿し込み易く、また、パッド発泡成形後の発泡品の脱型時に、発泡品と共に閉口プレートが可動するため、発泡品の成形型からの取り外しも容易になる。     According to the first aspect of the present invention, since the closing plate is rotatably provided in the molding die, the closing plate can be easily inserted into the opening of the trim cover set in the molding die, and foaming after pad foam molding is performed. Since the closing plate moves together with the foamed product when the product is removed from the mold, it is easy to remove the foamed product from the mold.

以下、本発明の一実施例を図面に基づいて説明する。
図面は表皮一体発泡品として、自動車用シートに備えるヘッドの製造装置を示す。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The drawing shows an apparatus for manufacturing a head provided in an automobile seat as a foam integrated with a skin.

図１は本発明に係る製造装置を示し、図中Ａは割り型からなる成形型の固定型、Ｂは同可動型を各々示し、固定型Ａの可動型Ｂの接合面には、左右一対の閉口部材たるプレート片１、１が図２に示すように、ヒンジ１Ａによって回転自在に設けてある。   FIG. 1 shows a manufacturing apparatus according to the present invention, in which A is a fixed mold of a split mold, B is the movable mold, and the joint surface of the movable mold B of the fixed mold A has a pair of left and right As shown in FIG. 2, plate pieces 1 and 1 serving as closing members are rotatably provided by a hinge 1A.

また、この固定型Ａと可動型Ｂの各々の接合個所には従来と同様にヘッドレストのステーを挿通するステー挿通溝２０、２０と、発泡液注入用のノズルの挿通部３０が設けてある。   In addition, at the joint portions of the fixed mold A and the movable mold B, there are provided stay insertion grooves 20 and 20 through which the headrest stays are inserted and a nozzle insertion portion 30 for injecting foaming liquid as in the conventional case.

プレート片１、１は図２矢印に示すように、１８０度回転するように固定型Ａに取付けられている。
プレート片１、１はその各外側の端縁間の幅が図４、図５に示すトリムカバーＨの開口部イの幅Ｗと同一に離間させて固定型Ａに取付けられている。 As shown by the arrows in FIG. 2, the plate pieces 1 and 1 are attached to the fixed mold A so as to rotate 180 degrees.
The plate pieces 1 and 1 are attached to the fixed mold A so that the width between their outer edges is the same as the width W of the opening a of the trim cover H shown in FIGS.

トリムカバーＨは多数の所定形状に裁断した布地(表皮材と発泡体製ワディング、ワディングカバーの積層体)をミシンで袋状に縫製して、その縫い代が内側になるように開口部イで裏返した構造で、開口部イが底部側に位置し、底部を構成する前底部１１と、後底部１０の各々の接合個所１０Ａ、１１Ａは図３、図４、図６、図７に示すように、内側に直角状に折曲され、開口部イを除く、開口部イの両側ロ、ロは縫糸１４、１４によって一体に縫着されている。図中１２、１３はトリムカバーＨの側面部を示す。   The trim cover H is made of a large number of fabrics cut into a predetermined shape (a laminate of skin material, foamed wadding, and wadding cover). As shown in FIG. 3, FIG. 4, FIG. 6, and FIG. The two sides of the opening a, except for the opening i, are sewed together by sewing threads 14 and 14. In the figure, reference numerals 12 and 13 denote side portions of the trim cover H.

このトリムカバーＨ内に略Ｕ字状に折曲するヘッドレストのステー１５が挿入される。図中ハはトリムカバーＨに設けた発泡液の注入孔、ニ、ニは同ステー１５を挿通する通孔を各々示す。   A headrest stay 15 that is bent in a substantially U shape is inserted into the trim cover H. In the figure, C indicates a foaming liquid injection hole provided in the trim cover H, and D and D indicate through holes through which the stay 15 is inserted.

以上のステー１５は開口部イから通孔ニ、ニ又は一方の通孔ニからトリムカバーＨ内に挿入して他方の通孔ニより外部に突出して図３の状態にし、この状態で、図１に示す固定型Ａ内にセットする。   The above stay 15 is inserted into the trim cover H from the opening a, or from one through hole D, and protrudes to the outside from the other through hole D in the state shown in FIG. Set in the fixed mold A shown in FIG.

このセット時にはステー１５の外部に突出する部分は、ステー挿通溝２０、２０に収容する。
これにより、トリムカバーＨの開口部イは、固定型Ａに設けたプレート片１、１側に位置する。 At the time of this setting, the portion protruding outside the stay 15 is accommodated in the stay insertion grooves 20, 20.
As a result, the opening a of the trim cover H is located on the side of the plate pieces 1 and 1 provided in the fixed mold A.

然る後、各プレート片１、１を回転させて開口部イの両端に挿入する。これにより、開口部イは長さ方向に引っ張られて前底布１１と後底布１０の接合個所１１Ａ、１０Ａは接合して開口部イは閉口される。   Thereafter, the plate pieces 1 and 1 are rotated and inserted into both ends of the opening a. As a result, the opening i is pulled in the length direction, the joining portions 11A and 10A of the front bottom cloth 11 and the rear bottom cloth 10 are joined, and the opening i is closed.

次に、可動型Ｂを固定型Ａに被せて挿通部３０から注入孔ハにノズルを挿し込み、図６、図７に示すようにトリムカバーＨ内にパッド発泡成形用の発泡液を注入して、パッド１６をトリムカバーＨ、ステー１５と一体に発泡成形してヘッドレストを製造する。   Next, the movable mold B is put on the fixed mold A, and a nozzle is inserted into the injection hole C from the insertion portion 30, and a foaming liquid for pad foam molding is injected into the trim cover H as shown in FIGS. The pad 16 is foam-molded integrally with the trim cover H and the stay 15 to manufacture a headrest.

この成形後、可動型Ｂを可動させてヘッドレストを固定型Ａより取り出す。この取り出す際、プレート１、１片は固定型Ａに回転自在に取付けられているため、ヘッドレストの取り出す動作によって回転して自然に開口部イから抜出される。   After this molding, the movable mold B is moved to take out the headrest from the fixed mold A. At the time of taking out, since the plates 1 and 1 are rotatably attached to the fixed mold A, they are rotated by the action of taking out the headrest and are naturally extracted from the opening a.

なお、図示する閉口プレートは一対の間隔をあけて配設したプレート片１、１であるが、このプレート片１、１の代わりに、開口部イの幅Ｗと同一の幅の一枚のプレートを閉口プレートとして利用してもよい。   The illustrated closing plate is a pair of plate pieces 1 and 1 arranged with a gap therebetween. Instead of the plate pieces 1 and 1, one plate having the same width as the width W of the opening A is used. May be used as a closing plate.

また、図示する開口部イはステー１５の外部に突出する部分の幅より狭いが、開口部イからステー１５をトリムカバーＨ内に挿入し易いように、ステー１５の外部に突出する部分の幅より広く形成してもよい。   Further, the illustrated opening a is narrower than the width of the portion protruding outside the stay 15, but the width of the portion protruding outside the stay 15 so that the stay 15 can be easily inserted into the trim cover H from the opening a. You may form more widely.

更に、開口部イは通孔ニ、ニを結ぶ線上に設けるも任意である。   Further, it is optional to provide the opening a on the line connecting the through holes D.

図示するものは表皮一体発泡品としてヘッドレストを示しているが、アームレストにも本発明は利用可能である。   Although what is shown shows the headrest as a skin-integrated foamed product, the present invention can also be used for armrests.
