Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil supply device installed in an oil supply station for supplying fuel to an automobile or the like.

[0002]

2. Description of the Related Art Conventional refueling devices include a ground-fixing type and a hose suspension type. The applicant of the present invention has proposed an oil supply device that makes it possible to easily process an oil supply hose that utilizes the advantages of both of them and has improved its defects (for example, Japanese Patent Application No. 5-152009).
No. 6-30813). That is, these are suspending a refueling hose having a refueling nozzle at one end from a moving body that runs in a hose processing case provided on the upper part of the weighing unit on the island, and the moving body moves to one end side in the hose processing case. When this is done, restraining means for temporarily restraining this moving body is provided.

[0003]

However, in the oil supply apparatus of Japanese Patent Application No. 5-130813, a permanent magnet is used as the restraining means, and therefore, if the attraction force of the moving body due to the magnetic force is too strong, it will be great when the hose is pulled apart. On the other hand, there is a drawback that it requires force and damages the hose. On the other hand, if the magnetic force is too weak, the moving body separates from the restraining means during refueling. Moreover, although the above-mentioned inconvenience is solved by using an electromagnet as the restraint means of the oil supply device of Japanese Patent Application No. 5-152009, it is necessary to wire in a narrow case, and the installation work becomes complicated, and When the hose was moved, the electric wire and the hose could come into contact with each other, resulting in disconnection.

Therefore, an object of the present invention is to provide an oil supply device which solves the above drawbacks and makes it easy to handle the oil supply hose.

[0005]

In order to achieve the above object, a refueling device of the present invention comprises a weighing unit provided on an island formed in a refueling site, and orthogonal to the island above the weighing unit. And a movable body guide provided along a long hole formed in the lower portion of the hose treatment case, and a movable body provided with a short pipe traveling along the movable body guide. An urging means for urging the moving body toward the island side, and a connection between the oil supply pipe from the measuring unit guided into the hose processing case and one side of the short pipe of the moving body. In a refueling device comprising a hose and a refueling hose having one end connected to the other side of the short pipe of the moving body and the other end suspended and a refueling nozzle at the tip, in the hose processing case,
An engaging portion that engages when the moving body moves to an end of the moving body guide, and a solenoid that controls the operation of the engaging portion,
Restraining means including a receiving means for receiving a release signal and outputting an operation signal to the solenoid is provided, and the weighing unit wirelessly transmits a release signal to the receiving means in conjunction with a signal based on the end of refueling. It is characterized in that a transmitting means is provided.

It is preferable that a supporting column is provided upright at the end of the measuring unit and the hose processing case is attached to the upper part of the supporting column in order to easily handle the oil supply hose. The engaging portion has a substantially central portion rotatably supported by the hose processing case, one end portion formed with a claw portion that engages with the moving body, and the other end portion serving as an operating shaft of the solenoid. It is preferable to provide the connected lever because the moving body can be reliably held with a simple structure. It is preferable that the solenoid is projected by the urging force of the coil spring when the actuating shaft is not energized and retracted by the urging force of the coil spring when the operating shaft is energized, since the energization time of the solenoid can be shortened and electricity consumption can be reduced. It is preferable that the solenoid is powered by a battery provided in the hose processing case because wiring can be eliminated and assembly can be simplified. The weighing unit includes
A nozzle switch is provided which is operated by attaching and detaching the refueling nozzle, and the transmitting means transmits a release signal in synchronism with the nozzle switch so that the refueling hose can be returned to its original position only by hanging the refueling nozzle on the nozzle hook. It is preferable in that it can

[0007]

According to the structure of the oil supply device of the present embodiment, the moving body that hangs the oil supply hose having the oil supply nozzle at the tip and travels in the hose processing case is temporarily held at one end by the restraining means during oil supply. When the refueling is completed, the releasing signal is issued by the transmitting unit, the receiving unit receives the releasing signal, and the releasing unit releases the restraint of the moving body. As a result, the moving body with the refueling hose suspended automatically returns to the standby position by the biasing means. Therefore, unlike the restraint means using a magnet, it is not necessary to strongly pull the hose to release the restraint, so that the hose is not damaged.
