- the vehicle supported by the transport hanger from below can be received by raising the lifting mobile, and the vehicle lowered by the lifting mobile can be moved up and down the vehicle support. After receiving it at a predetermined height by a suitable supporting part, the tire of the vehicle body is brought into contact with the ground by lowering the supporting part and transported to the next process.
- the vehicle body is tilted upward until the transfer rail suspending the transfer hanger reaches below the part assembly process force transfer device, so that the vehicle body is It is possible to receive at a predetermined height in the support device, and to return the transport hanger to the top of the line after transferring the vehicle body with the transfer device.
- the lower part assembly process force reaches the transfer device. It is necessary to incline the transport rails obliquely upward until the transfer is completed, which causes a problem that the line length becomes long. Also, it is conceivable that tires are mounted inside the transfer device to shorten the line length. Since this transfer device has a body support device, this body support device hinders work, It was difficult. Further, since the conventional transfer device is provided with a vertically movable body and a vehicle body support device having complicated structures, the manufacturing cost has been increased.

As a result, the vehicle body is directly transferred from the transport hanger to the lower support transport line, and is set on the support transport line.
- the conventional vehicle body can be transferred from the transfer hanger to the support transfer line. This eliminates the need to provide a device having a complicated structure such as a vertical moving body or a vehicle body support device, thereby reducing the manufacturing cost.
- it is not necessary to support the vehicle body at a predetermined height with the support portion of the vehicle body support device as in the related art it is necessary to form the transfer line between the lower part assembly process force transfer device and the transfer device inclined. Gone , The line length can be shortened.
- the elevating device moves the elevating rail to a position that is continuous with the transport rail of the suspended transport line and the support that supports and transports the lower side of the vehicle body. It is preferable to move the transport hanger to a position where the vehicle body is placed on the holding transport line and to a position that is continuous with a return rail for returning the transport hanger to the top of the suspended transport line.
- the transport hanger can be transferred by raising the elevating rail to the return rail normally installed at a position higher than the transport rail. Therefore, it is not necessary to form the return rail at an inclination, and the line length can be shortened accordingly.
- the present invention provides a supporting and conveying device that supports and transports the lower side of the vehicle body from a suspended transport line that transports the vehicle body while being suspended from above by a transport hanger that travels along a transport rail.
- the present invention relates to a method of transferring a vehicle body for transferring the vehicle body to a line.
