DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping apparatus, and more particularly to a shipping apparatus configured to selectively ship different oil types using the same loading arm.

[0002]

2. Description of the Related Art For example, in a shipping device for shipping an oil liquid, when a tank truck arrives at a shipping stage, a car number card of the tank truck is read. As a result, the reservation data including the reserved quantity set for each hatch of the tank for the tank lorry corresponding to the vehicle number data is output from the upper management device of the oil depot to the shipping control device in the shipping stage.

[0003] After connecting the grounding device to the tank truck, the driver inserts and sets a loading arm of the oil type to be loaded on each hatch of the tank, and sets the loading arm in a hatch card reader provided on the loading arm. Read the hatch card attached to the filler port of the hatch with a chain or the like. Subsequently, if the driver sets the loading amount using the loading amount setting switch of the loading arm and operates the shipping start switch, the shipping control device will determine the oil type of the loading arm, the loading amount and the reservation data. A shipping permission signal is output on condition that the reserved oil type and the reserved quantity corresponding to the hatch match, and that the earth interlock, loading arm interlock, and the like have been completed.

As a result, the pump connected to the loading arm in the shipping stage is started and the metering valve is opened, and the oil liquid is loaded in each hatch of the tank truck. However, in the above configuration, there is a problem that a considerable installation space is required because the loading arms are required at least for the number of types of the oil liquid.

[0005] Therefore, in a shipping apparatus, it has been considered that a plurality of oil types can be selectively shipped from one loading arm. In this case, one loading arm is connected to the oil type via a switching valve. Are connected to a plurality of different pipelines. Therefore, by switching the switching valve,
For example, after shipping gasoline to the first hatch, kerosene can be shipped to the second hatch using the same loading arm.

[0006]

However, in a conventional shipping apparatus configured to be able to selectively ship different oil types using the same loading arm, when the shipment of one oil type is completed, the loading arm When one oil type remains in the hatch and another oil type is loaded on the hatch by switching the switching valve, first the oil type remaining in the loading arm is loaded on the hatch, and then the other oil type is loaded. Will be loaded on this hatch. Therefore, for example, when gasoline is loaded into the first hatch and then kerosene is loaded into the second hatch using the same loading arm, the kerosene is loaded after the gasoline remaining in the loading arm is loaded into the second hatch. Due to the loading, there is a problem that a different oil type mixing accident (contamination) occurs in which gasoline and kerosene are mixed in the second hatch.

Further , as a conventional shipping device, for example,
There is one disclosed in Japanese Patent Publication No. 49-61709. This
