DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unloading management apparatus for a gas station, which has a function of recording the progress of unloading of a tank at a gas station by a lorry and issuing an unloading log.

[0002]

2. Description of the Related Art When a lorry unloads a tank at a gas station, a gas station staff is present to check the unloading amount and the like on the spot after unloading. On the other hand, from the viewpoint of improving transportation efficiency and the like, replenishment is carried out in a part of time when traffic is relatively small, such as early morning, late night, and holiday. However, in such a time zone, since the gas station is not in business, there is no witness, and it is impossible to confirm the unloading amount at the time of replenishment.

[0003]

In order to solve such a problem, when replenishing an oil storage tank from a tank lorry as disclosed in JP-A-6-100089, the amount of oil in an underground tank from the start of replenishment is reduced. An apparatus has been proposed which monitors and records the amount of oil, the type of oil, etc. before and after unloading of the oil storage tank and issues an unloading log when replenishment is completed. According to this, when replenishment to the oil storage tank is completed normally, lubrication work can be effectively managed without requiring a witness, but replenishment to the oil storage tank becomes impossible. It is not possible to grasp the abnormal condition, and it is not possible to determine whether the cause of the failure to perform the lubrication work is on the gas station side or on the lorry side, and there is a possibility that the relationship of trust may be damaged.
The present invention has been made in view of such circumstances, and its purpose is to record not only the date and time of receipt, the amount of receipt, but also the entire process of replenishment work from the lorry to the oil storage tank. It is to provide an unloading device for a gas station.

[0004]

According to the present invention, there is provided a work for replenishing fuel oil to an oil storage tank of a gas station by a lorry equipped with an operating device for controlling an oil type and a lubricating amount. In the unloading management device for a gas station that monitors and issues unloading logs, the amount of oil in the oil storage tank from the start of replenishment is monitored, and at least the oil storage tank that has been unloaded, the lubrication date and time, and the unloading amount are recorded after replenishment is completed. ,
An error signal output from the operating device is collected and recorded after the point at which the lorry and the oil storage tank are connected by an oiling hose.

[0005]

When the unloading cannot be performed, an error signal from the operating device is recorded so that the cause can be specified.
