Abstract

An automatic supply system of a consumable material includes: an automatic supply device that automatically supplies a consumable material to a vehicle capable of being loaded with a cargo; and a control device that obtains loading information indicating whether or not the cargo is loaded on the vehicle, and is able to control an automatic supply of the consumable material to the vehicle based on the obtained loading information, wherein, when the control device determines that the cargo is loaded on the vehicle from the obtained loading information, the control device controls the automatic supply device not to perform the automatic supply of the consumable material to the vehicle.

Claims

1. An automatic supply system for supplying a consumable material comprising:

an automatic supply device that automatically supplies the consumable material to a dump truck having a vessel configured to be loaded with a cargo;

a cargo detection unit configured to detect whether or not the cargo is loaded on the vessel of the dump truck as loading information which is transmitted to a control device; and

the control device that obtains the detected loading information, and is configured to control an automatic supply of the consumable material to the dump truck based on the obtained loading information,

wherein when the control device determines that the cargo is not loaded on the vessel of the dump truck from the obtained loading information, the control device controls the automatic supply device to perform the automatic supply of the consumable material to the dump truck, and when the control device determines that the cargo is loaded on the vessel of the dump truck from the obtained loading information, the control device controls the automatic supply device not to perform the automatic supply of the consumable material to the dump truck.

2. The automatic supply system according to claim 1, wherein the cargo detection unit comprises a payload meter that detects loadage of the cargo loaded on the dump truck.

3. The automatic supply system according to claim 1, wherein the automatic supply device automatically supplies the consumable material to the dump truck via a refueling opening in the dump truck, the refueling opening being disposed below the vessel and in a position interior to an outer edge of the vessel.

4. An automatic supply system for supplying a consumable material comprising:

an automatic supply device that automatically supplies the consumable material to a dump truck having a vessel configured to be loaded with a cargo;

a cargo detection unit configured to detect whether or not the cargo is loaded on the vessel of the dump truck as loading information which is transmitted to a control device; and

the control device configured to control the automatic supply device,

wherein the automatic supply device automatically supplies the consumable material to the dump truck via a refueling opening in the dump truck, the refueling opening being disposed below the vessel of the dump truck and in a position interior to an outer edge of the vessel of the dump truck, and

wherein when the control device determines that the cargo is not loaded on the vessel of the dump truck from the obtained loading information, the control device controls the automatic supply device to perform the automatic supply of the consumable material to the dump truck, and when the control device determines that the cargo is loaded on the vessel of the dump truck from the obtained loading information, the control device controls the automatic supply device not to perform the automatic supply of the consumable material to the dump truck.
