In the state shown in FIG. 2, a slight gap is formed between the lower ends of the stopper bolts 28, 28 and the stopper protrusions 29, 29, and the guide rails 25, 25 are arranged around the swing shafts 23, 23 in the arrow direction. When the guide rails 25, 25 swing to the direction A and become the state of the chain line in FIG. 3, the inner ends 25 1 , 25 1 of the guide rails 25, 25 are slightly separated from the floor F, and the outer ends 25 2 , A slight gap is maintained between 25 2 and the floor surface F.
【００１３】 図３から明らかなように、旋回軸１２と車輪１６，１６との距離は、搬送台車 Ｄの全長Ｌの略２分の１に設定されており、搬送台車Ｄを旋回装置Ｔにセットし た状態において、旋回軸１２は搬送台車Ｄの略中央部に位置することになる。As is apparent from FIG. 3, the distance between the turning shaft 12 and the wheels 16 and 16 is set to be approximately one half of the entire length L of the carriage D, and the carriage D is set to the turning device T. In the set state, the revolving shaft 12 is located at the substantially central portion of the transport carriage D.
【００１４】 次に、前述の構成を備えた本考案の実施例の作用について説明する。Next, the operation of the embodiment of the present invention having the above-mentioned configuration will be described.
【００１５】 組立ラインの一側の床面に設けられた旋回装置Ｔは、搬送台車Ｄをセットしな い状態では、一対のガイドレール２５，２５の内端部２５1 ，２５1 が、自重で 揺動軸２３，２３回りに揺動して床面Ｆに当接している（図２参照）。この状態 から部品を搭載した搬送台車Ｄを移動させ、その固定輪２，２をガイドレール２ ５，２５の内端部２５1 ，２５1 から進入させる。The turning device T provided on the floor surface on one side of the assembly line has a structure in which the inner end portions 25 1 and 25 1 of the pair of guide rails 25 and 25 are self-weighted when the carrier D is not set. And swings around the swing shafts 23, 23 and is in contact with the floor surface F (see FIG. 2). From this state, the carrier truck D on which the parts are mounted is moved, and the fixed wheels 2 and 2 thereof are inserted from the inner end portions 25 1 and 25 1 of the guide rails 25 and 25.
【００１６】 固定輪２，２が揺動軸２３，２３の位置を越えると、搬送台車Ｄの重量でガイ ドレール２５，２５は揺動軸２３，２３回りに図３の実線位置から鎖線位置に揺 動する。その結果、ガイドレール２５，２５の内端部２５1 ，２５1 は床面Ｆか ら離間し、またストッパボルト２８，２８がストッパ突起２９，２９に当接する ことにより、外端部２５2 ，２５2 は床面Ｆから僅かに離間した位置に停止する 。このとき、ガイドレール２５，２５の外端部２５2 ，２５2 が低くなるように 傾斜するため、搬送台車Ｄの固定輪２，２はガイドレール２５，２５の外端部２ ５2 ，２５2 に設けた台車ストッパ２６，２６に当接して位置決めされる。When the fixed wheels 2 and 2 exceed the positions of the swing shafts 23 and 23, the guide rails 25 and 25 are moved around the swing shafts 23 and 23 from the solid line position in FIG. Shake. As a result, the inner end portions 25 1 and 25 1 of the guide rails 25 and 25 are separated from the floor surface F, and the stopper bolts 28 and 28 abut the stopper protrusions 29 and 29, so that the outer end portions 25 2 and 25 1 , 25 2 stops at a position slightly separated from the floor surface F. At this time, since the outer end portion 25 2, 25 2 of the guide rails 25, 25 is inclined to be lower, outer end portions 2 5 2, 25 of the fixed wheels 2 are guide rails 25, 25 of the platform car D The carriage stoppers 26, 26 provided at 2 are contacted and positioned.
【００１７】 この状態で、作業員は搬送台車Ｄの片側に搭載した部品を取り出して組立ライ ン上の車体に組付け、搬送台車Ｄの片側に搭載した部品が無くなると、反対側の 部品を取り出すべく搬送台車Ｄを１８０°旋回させる。即ち、搬送台車Ｄの固定 輪２，２側の端部を水平方向に押圧すると、旋回装置Ｔは搬送台車Ｄを支持した 状態で、一対の車輪１６，１６を床面Ｆ上を転動させながら旋回軸１２回りに旋 回する。In this state, the worker takes out the parts mounted on one side of the carrier truck D and assembles them on the vehicle body on the assembly line. When the parts mounted on one side of the carrier truck D are exhausted, the parts on the opposite side are removed. The carriage D is turned 180 ° to take it out. That is, when the fixed wheels 2 and 2 side ends of the transport carriage D are pushed in the horizontal direction, the turning device T rolls the pair of wheels 16, 16 on the floor surface F while supporting the transport carriage D. While turning around the turning axis 12.
【００１８】 このとき、ガイドレール２５，２５の内端部２５1 ，２５1 及び外端部２５2 ，２５2 は共に床面Ｆから離間しており、且つ固定輪２，２がガイドレール２５ ，２５によって支持されているため、搬送台車Ｄは一対の車輪１６，１６及び一 対の旋回輪３，３に支持されて軽い力で容易に旋回することができる。しかも、 旋回軸１２が搬送台車Ｄの略中央部にあるため、搬送台車Ｄは自己の全長Ｌを直 径とする極めて狭い円内で旋回することができる。搬送台車Ｄを元の状態に戻す には、旋回装置Ｔを同方向に更に１８０°旋回させるか、逆方向に１８０°旋回 させれば良い。[0018] At this time, the inner end 25 1, 25 1 and an outer end portion 25 2 of the guide rails 25, 25, 25 2 are spaced apart both from the floor F, and the fixed ring 2, 2 guide rails 25 , 25, the carrier cart D is supported by the pair of wheels 16, 16 and the pair of turning wheels 3, 3 and can be easily turned by a light force. Moreover, since the swivel shaft 12 is located substantially at the center of the transport carriage D, the transport carriage D can swivel within an extremely narrow circle having its entire length L as a straight diameter. In order to return the carrier vehicle D to its original state, the turning device T may be turned 180 ° in the same direction or 180 ° in the opposite direction.
【００１９】 以上、本考案の実施例を詳述したが、本考案は前記実施例に限定されるもので なく、種々の設計変更を行うことが可能である。Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various design changes can be made.
【００２０】 例えば、実施例の搬送台車Ｄは一対の固定輪２，２及び一対の旋回輪３，３を 備えているが、本考案は一対の固定輪２，２及び１個の旋回輪３を備えた搬送台 車Ｄに対しても適用することができる。また、旋回アーム１４，１４は必ずしも ２本必要ではなく、１本であっても良い。For example, the carrier truck D of the embodiment includes a pair of fixed wheels 2 and 2 and a pair of turning wheels 3 and 3. However, the present invention uses a pair of fixed wheels 2 and 2 and one turning wheel 3. The present invention can also be applied to a carrier vehicle D equipped with. Further, the number of turning arms 14 and 14 is not necessarily two, and may be one.
【００２１】[0021]
以上のように本考案によれば、旋回軸回りに旋回可能なガイドレール上に搬送 台車の固定輪を支持して床面から離間させ、搬送台車の重量をガイドレールに設 けた車輪と搬送台車の旋回輪とによって支持しながら前記旋回軸回りに旋回させ ることができる。これにより、狭いスペースでの搬送台車の旋回が可能になるだ けでなく、搬送台車の旋回に要する作業員の労力を大幅に軽減することができる 。 As described above, according to the present invention, the fixed wheels of the carriage are supported on the guide rails that can be swiveled around the swivel axis and separated from the floor surface, and the weight of the carriage is set on the guide rails and the carriage. It is possible to turn around the turning axis while being supported by the turning wheel. As a result, not only is it possible to turn the carrier truck in a narrow space, but it is also possible to greatly reduce the labor of the operator required to turn the carrier truck.
