A conveying method for conveying green tires from storing devices, disposed near building machines, to curing machines and attaching them to the curing machines is disclosed wherein a green tire delivery demand signal is emitted, from a specific curing machine among a plurality of curing machines, to a control system which stores the corresponding relationships between the respective storing devices and the respective curing machines and the quantities and kinds of green tires stored in the storing devices. The control system which receives this demand signal sends a signal, indicating the curing machine which has emitted the demand signal and the corresponding specific storing device, to an automatic truck supporting and carrying thereon a mechanism which is capable of withdrawing a green tire from the storing device, having it suspended thereon, and loading it onto the curing machine. The automatic truck is capable of running on rails laid and supported at a suitable height above the storing devices and curing machines, and on receipt of this signal, the truck moves to the corresponding storing device, carries the green tire suspended thereon, runs to the specific curing machine, which has emitted the demand signal, while suspending the green tire thereon, and loads the green tire onto the specific curing machine. |

DETAILED DESCRIPTION The present invention has been completed as a result of our research work made with a view to overcoming the foregoing defects involved in the conventional technique.
Namely, it is a primary object of the present invention to provide a conveying method in which vertical loaders, capable of suspending thereon green tires, are mounted on an automatic device capable of automatically running between storing devices and curing machines, and this automatic conveying truck automatically performs the withdrawal of green tires from the storing devices and the loading of the same upon the curing machine.
In the tire manufacturing process, various stations such as those for the inspection of the green tires, coating of a parting agent, pre-heating of the green tires, and boring of the green tires for leakage of melting air, are disposed between the building machines and the curing machines.
Another object of the present invention is to increase the manufacturing efficiency by controlling all of these intermediate steps by one control system.
In accordance with the present invention, there is provided a conveying method for conveying green tires, from storing devices disposed near building machines, to curing machines and loading them onto the curing machines, wherein a green tire delivery demand signal is emitted, from a specific curing machine among a plurality of the curing machines, to a control system which stores the corresponding relationships between the respective storing devices and the respective curing machines, and the quantities and kinds of green tires stored in the storing devices.
The control system which receives this demand signal sends a signal, indicating the curing machine which has emitted the demand signal and the corresponding specific storing device, to an automatic truck supporting and carrying thereon a mechanism having the function of withdrawing a green tire from the storing device, suspending it thereon, and loading it onto the curing machine.
The automatic truck is capable of running on rails laid and supported at a suitable height above the storing devices and curing machines, and on receipt of this signal, the automatic truck moves to the corresponding storing device, carries the green tire suspended thereon, goes to the specific curing machine which has emitted the demand signal while suspending the green tire thereon, and loads the green tire onto the specific curing machine
