Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a car conveyor that supports either the front or rear wheels of an automobile on a conveyor and transfers the other wheels onto the floor to transport the automobile.

Conventional technology When transporting a car using a floor conveyor, conventionally, the shaft support of the front wheel in the transport direction is supported on the conveyor to lift the wheel off the floor, and the other wheel is transferred onto the floor for transport. It was. However, with this conventional method, as the structure of the shaft support differs depending on the vehicle model, the structure of the conveyor-side receiver that receives the shaft support has to be changed depending on the vehicle model, which is inconvenient. In some cases, there is no suitable structural part to do so.Furthermore, if the movement of the vehicle and the support gets out of synchronization when the shaft support is placed on the support in the loading area, the support support may shift and cause oil leakage. There were cases where parts such as bread were damaged by the receiver.

, Problems to be Solved by the Invention The present invention solves the problem by directly attaching the wheel (tire) to the wheel (tire) instead of the wheel shaft support.
The purpose of the present invention is to propose a vehicle transfer conveyor that can be used commonly for various types of vehicles and that can transport vehicles without damaging them.

Means for Solving the Problems The present invention provides a carrier which is driven to run on under-floor rails by an under-floor drive chain, and supports the front wheels of the vehicle in the direction of transport on the floor by supports on both sides. The gist is a car transfer conveyor in which a pedestal is installed so that it can freely rotate horizontally, and furthermore, in a non-transfer section or a carrier return section, the cradle is rotated so that the holders on both sides are aligned in the transfer direction, and the pit width of the transfer path is adjusted. This made the construction of the conveyor easier.

Function: The support of the present invention stably supports automobile wheels, and the same support can be used over a wide range of vehicle types that differ in wheel width, left and right wheel spacing, etc. The tool is also easy to manufacture.

However, since the cradle of the present invention supports the wheels, it becomes longer in the lateral direction than the conventional one, so in moving sections where the pedestal is not used, the pit width of the transfer path can be shortened by orienting the pedestal in the direction of movement. .

Embodiment FIG. 1 is a layout diagram of an embodiment of the present invention, in which a conveyor is installed in an underfloor pit provided along a circulation path 1, and a conveyor is installed from a loading position 2 to an unloading position 3.

The engagement between the button 18 and the button 18 is released, and the subsequent carrier coupling body 12a stops.

Effects of the Invention Since the present invention supports the front wheels of the automobile in the transfer direction on a conveyor and transfers the vehicle, it can be commonly used for vehicle types with different wheel spacing and wheel widths, and it is also easy to load. There is no risk of damaging the vehicle body or other structural parts, and since the rear wheels prevent the vehicle from tilting from side to side during transportation, only a small amount of strength is required to prevent the pedestal or carrier having the pedestal from tilting from side to side. There are other effects. Furthermore, since the pedestal is held vertically on the return side of the conveyor, the focus width on the return side becomes small, and the conveyor can be configured into a single book.
