Abstract

PROBLEM TO BE SOLVED: To judge the kind of oil with high reliability without increasing the passage resistance of an oil injection hose by receiving the oil kind discrimination piece of an oil tank as a radio signal and comparing this data with the oil kind data of the hatch designated on a keyboard and opening the bottom valve of the hatch only when both data coincide with each other. SOLUTION: Discrimination piece reading means 22, 47 read the oil kind discrimination pieces provided in the vicinity of fourth and third couplings 20, 18 to output them by a wireless system. A wireless receiving means (antenna) 35 receives the signals from the discrimination piece reading means 22, 47. A control means 31 compares the received read result with the kind of oil of the hatch number from a hatch number inputting keyboard 32 and opens the bottom valves 5-8 of the hatches 1-4 designated by the keyboard 32 when both of them coincide with each other. By this constitution, the kind of oil can be judged with high reliability without increasing the passage resistance of oil injection hoses 15, 45.

However, since the judgment is manually performed, there is a possibility that an error sometimes occurs. For this reason,
As described in Japanese Patent Publication No. 3-249380, the male coupling provided on the discharge pipe of the lorry is provided with oil type determination means, and the female coupling provided on the oil supply pipe of the oil storage tank is provided with a length depending on the oil type. There has also been proposed one having different projections and mechanically transmitting the length of the projections to oil type determination means by a wire inserted into an oiling hose.

[0003]

However, since the result of the oil type judgment is transmitted by the wire, there is a possibility that a judgment error may occur due to an error due to the play and extension of the wire, or the wire is cut off because the wire is accommodated. There are problems that the area becomes smaller and the time required for lubrication becomes longer. The present invention has been made in view of such a problem, and an object thereof is to improve a flow rate resistance of an oil-filling hose and to determine a type of oil with high reliability. To provide an oil mixing prevention device.

An identification piece reading means for reading the oil type identification piece provided near the third coupling for wirelessly outputting in the vicinity of the fourth coupling, and an identification piece reading means mounted on the vehicle for reading from the identification piece reading means. A wireless receiving means for receiving a signal, a keyboard for inputting a hatch number, the received reading result and the oil type of the hatch number from the keyboard are compared, and if they match, the bottom valve designated by the keyboard can be opened. It was equipped with a control means to smooth out.

[0005]

[Function] The oil type data of the identification piece indicating the oil type of each oil storage tank is received as a wireless signal, this data is compared with the oil type data of the hatch specified by the keyboard, and the bottom valve is opened only when they match. It is possible.
