In this case, since it is not possible to move the trolley conveying moving body 9 to a predetermined position on the lifting guide rail 29 by the driving means 11, it is necessary to move the moving body 9 parallel to the lifting guide rail 29 as is well known in the art. A delivery means can also be used.

In a state in which the carriage transfer vehicle 9 is stopped at a predetermined position on the lifting guide rail 29 and the carriage 3 is stopped at a predetermined position directly above the carriage transfer unit 9, the carriage transfer means 28 is moved. The elevating movable body 31 is raised by the elevating drive means 32, and the elevating guide rail 29 is connected to the guide rail 10 located at a high position on the conveyance path. During the ascending process of the elevating guide rail 29, the carriage transport moving body 9 on the elevating guide rail 29 has its fitting support portion 20 of its cart support base 18 fitted into the fitted portion 19 of the transport cart 3 from below. By aligning them, the transport vehicle 3 supporting the transported object W is lifted to a predetermined height.

If the carriage 3 is transferred onto the carriage transport moving body 9 of the carriage support conveyor 2 at the end of the carriage route of the carriage conveyor 1 as described above, for example, if the carriage 3 is placed in parallel with the lifting guide rail 29 The mobile body 9 for transporting the trolley is moved by the mobile body pulling and sending means.
from above the lifting guide rail 29 to the guide rail 10 located on the conveyance path of the trolley support conveyor 2.
By sending it upward, the trolley conveyance moving body 9 is propelled along the guide rail 10 by the drive means 11. Therefore, the object W to be transported, while being supported by the transport vehicle 3, is transported along the transport route of the conveyor 2 by the transport vehicle 9 of the transport vehicle 2, together with the transport vehicle 3.

The conveyor 2 for supporting and transporting the cart performs a conventionally well-known automatic storage operation by the action of the movable pusher 26 of the driving means 11 and the operating section 22 for releasing the driving of the subsequent moving object on the side of the moving object 9 for transporting the cart. In the storage line set inside, it is possible to store the carriage transport moving bodies 9 that support the transported objects W via the transport carriages 3 as described above in a string. At this time, the moving body 9 for transporting the trolley
(first trolley 13 and fourth trolley 1)
6) protrudes forward and backward relative to the transported objects W, so there is no risk of the transported objects W colliding with each other.

In the embodiment, the carriage 3 is transferred from the carriage-type conveyor 1 to the carriage support conveyor 2, but it is also possible to transfer it in the opposite manner.

(Operations and Effects of the Invention) As described above, according to the conveying device of the present invention, a trolley-type conveyor, which has a simple structure but does not have an automatic storage function, can be used to convey objects to be conveyed in, for example, a painting line or a drying oven line. In a general conveyance line including a storage line, objects can be conveyed by means of a cart-supported conveyor having an automatic storage function.

In this way, two types of conveyors can be used depending on the conveyance line, but according to the present invention, the objects to be conveyed supported on the conveyance truck in the trolley-type conveyor are conveyed together with the conveyor by the truck support. Since the object is transferred to the trolley conveyance moving body of the conveyor, the object can be transferred between the two conveyors without touching the object at all. In addition, the transfer of the carrier can be carried out by simply raising and lowering the carriage transporting body of the carriage supporting and transporting conveyor using the lifting guide rail, which is efficient and can shorten the cycle time of the entire transporting operation. .
