BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting method and a mounting device for mounting exhaust system parts such as an exhaust pipe and a silencer from below onto a vehicle body that is horizontally conveyed by an overhead conveyor.

0002

[Prior Art] Conventionally, the work of attaching exhaust system parts such as exhaust pipes and silencers from below to a car body that is conveyed horizontally by an overhead conveyor was done by
Workers lift the exhaust pipe and silencer one by one in the order of the process, bring them to the underside of the vehicle, and install them. In such conventional methods, each component of the exhaust system has a complicated shape and is heavy, making it difficult to install, requiring the worker to perform the installation in a crouched position, and requiring a long work time. There are problems such as increased fatigue due to this, and there is a demand for automation of the installation work.

[0003] Therefore, Japanese Utility Model Application No. 2-145937 has been proposed as an automatic assembly device for exhaust system parts. This technique involves transporting exhaust system components below the vehicle body on a pallet, stopping the transportation of the vehicle body, and attaching the exhaust system components on the pallet to the underside of the vehicle body.

0004

[Problems to be Solved by the Invention] The above-mentioned conventional automatic assembly equipment temporarily stops transporting the vehicle body and performs the assembly work, so the automobile production line has to be temporarily stopped. This is undesirable because parts are transported and assembled on pallets, so a special pallet is required, and when considering mass production, it is necessary to load parts into many car bodies and to synchronize the loading with car body transport. Taking this into consideration, it requires a large number of pallets, a device for loading and unloading the pallets, the device is large-scale and has a complicated structure, and it is difficult to easily adapt to changes in model etc. However, due to the above, the total cost increases and there are disadvantages such as being economically disadvantageous.

The present invention has been made to solve the problems of the prior art, and its purpose is to make the work easier, reduce worker fatigue, and install exhaust system parts efficiently. The installation work can be carried out while moving in synchronization with the transportation of the vehicle body without stopping it, The storage space for the exhaust system is minimized, and it can be easily adapted to different models. It is an object of the present invention to provide a method and apparatus for attaching exhaust system parts, which have advantages such as eliminating the loading/unloading device, having a simple structure, and being able to construct a compact installation line for the exhaust system parts.

[0006]

[Means for Solving the Problems] The means for solving the above problems are a process of combining and assembling exhaust system parts such as exhaust pipes and silencers that have been transported separately, and A process in which system parts are delivered to a storage conveyor and transported in sequence; a process in which exhaust system parts assembled downstream of the storage conveyor are received and transferred to a mounting trolley in the mounting position on the vehicle body; and a process in which they are transferred to a mounting trolley. and a step of attaching the exhaust system parts to the car body, and the mounting cart is moved in synchronization with the conveyance of the car body.

[0007] Furthermore, a storage conveyor is provided with stoppers provided at predetermined intervals so as to be able to appear and retract freely, and transports the assembled exhaust system parts from upstream to downstream, and a storage conveyor is disposed upstream of the storage conveyor, and is provided with stoppers that can be moved in and out of the exhaust system at predetermined intervals. an assembly device for exhaust system parts, which is provided with a receiving part on the conveyor that can freely protrude and retract from the conveyor, and a receiving part for the exhaust system parts that is arranged downstream of the storage conveyor and can be raised and lowered; A transfer device that receives exhaust system components on a conveyor at a receiving section, moves the receiving section to a transfer position, and transfers the assembled exhaust system components onto a mounting trolley; and the exhaust gas received from the transfer device. This is an equipment for mounting exhaust system parts onto a car body, which consists of a mounting cart that moves the exhaust system parts to the mounting position on the car body and attaches the exhaust system parts to the car body. A clamper for moving the mounting cart is provided so as to be freely engageable and detachable from the vehicle body transfer hanger.

[0008]

[Operation] According to the above means, the exhaust system parts are assembled at the upstream part of the storage conveyor, are transported downstream on the conveyor and stored, and at the downstream part are transferred by the transfer device to the cart for mounting on the vehicle body. The mounting cart moves in synchronization with the transportation of the vehicle body, allowing exhaust system components to be attached to the vehicle body.
