In step S8, data of the identification portions of the tank chambers 6A, 6B, and 6C is input from the identification sensor 12 to the tank number determination means 23 as the amount of movement.

Next, in step S9, these input data are compared with the tank number identification data taken in from the register 16B of the ROM 16, and the amount of movement is detected to be mA for the rod 14A (length 7!A), for example. If so, the tank to which loading arm 3 is connected is in tank chamber 6A.
It is specified that This is because, although there are multiple loading arms 3, the identification sensor 12 is unique to each loading arm 6, and by looking at which identification sensor 12 is activated, it is possible to identify the loading arm 6. This is because the tank room can be identified.

In step SIO, register 16C of ROM16
When the oil type data is read on the CPU 15, the process proceeds to step Sll. In step Sll, when the signal from the identification sensor 12 is input to the oil type determining means 24, the oil type determining means 24 uniquely applies the signal to the loading arm 3 to which the identification sensor 12 is attached and to which the signal is input. The data is compared with the oil type data provided in , the type of oil in the supply side storage tank 4 is specified.

In step S12.13, loading amount setting switch 1
The loading amount set in step 8 is read by the loading amount determining means 27, and the data specified thereby is sent to the cargo handling permission determining means 26.

Then, in step 514, the cargo handling permission determination means 2
Tank number and oil type specified by 6.

The actual loading amount is ROM16. The data is compared with the data in RAM 17. YES (YES) when the oil type in the supply side storage tank 4 matches the oil type scheduled to be loaded in the predetermined tank chambers 6A, 6B, and 6C of the tank truck 6, and the loading amount is less than the scheduled loading amount. permission), and the process advances to step S15. If the loading amount exceeds the scheduled loading amount, it is determined as No (not permitted), and step S1
Proceed to step 6.

In step S15, the cargo handling valve 5 is opened via the actuator 22A, and the quantitative shipping device 22 performs cargo handling after confirming that a start switch (not shown) has been pressed.

In step S16, the cargo handling valve 5 is closed via the actuator 22A, and shipping is stopped.

Note that during cargo handling, if the overflow sensor 19 detects an abnormal liquid level due to a failure of the quantitative shipping device 22, the signal is immediately sent to the cargo handling permission judgment means 26, and the cargo handling permission judgment means 26 detects the cargo handling valve. 5 is sent to the actuator 22A, and the oil loading and unloading is stopped (step 517).

According to the above configuration, when loading a plurality of oils such as gasoline, kerosene, and light oil from the supply side storage tank 4 to the tank lorry 6 via the loading arm 3, the loading arm 3 is connected to the tank chambers 6A, 6B of the tank lorry 6. , 6C, the tank numbers of the tank chambers 6A, 6B, and 6C of the tank lorry 6 can be specified by the tank number determining means 23 described above. Therefore, unlike in the conventional case, the work of connecting the detection device provided in each tank chamber of the tank truck to the detector provided in each loading arm is eliminated, and the tank number of the tank chamber of the tank truck IJ 6 can be identified with a simple task. can do. In other words, the operator does not need to do any special work to determine the tank number, and can easily find the tank room 6A.

The tank numbers 6B and 6C can be identified, and in turn, it is possible to prevent cargo handling of different oil types.

In addition, it is possible to eliminate the detection device connected to the detector as described in the conventional example, and eliminates unspecified or erroneous identification of the tank numbers of the tank chambers 6A, 6B, and 6C that occur due to deformation during storage. It produces the effect that can be achieved.
