Description

TECHNICAL FIELD The present invention relates to an oil supply device with a vapor recovery.

[Prior Art] It is known that when fueling a fuel tank of an automobile from a fueling machine, there is a risk of fire due to static electricity generated by friction due to a flow of oil, friction of clothes, and the like. There is. At that time, the presence of vapors of oil, especially gasoline, is not preferable. Therefore, there is known a technique for collecting a vapor generated during refueling by providing a vapor recovery hose on a refueling nozzle of a refueling machine.

The conventional type has a vapor recovery hose in parallel with a hose for vapor recovery, and both hoses are clamped, resulting in poor operability.In particular, when applying this type of technology to a suspension type fueling device, , The means for winding and unwinding the two hoses connected to the fueling nozzle at the same time and the means for storing and storing the two hoses, for example, two hose reels are necessary, and therefore, the structure is practically extremely large. It becomes complicated and cannot be implemented. In particular, in a suspension type refueling device that can move laterally, the suspension point of the refueling hose must be movably supported, and it is not possible to provide a similar movement support means in the limited space for the vapor recovery hose. Nearly impossible.

Japanese Patent Application Laid-Open No. 57-17793 discloses a technique in which a vapor recovery hose is wound around an oil supply hose. However, in such a known technique, the refueling hose is not laterally moved, and therefore, the lateral movement processing for the vapor recovery hose cannot be performed.

Also, Japanese Utility Model Publication No. 50-12860 discloses a technique in which a curled hose is used in an operating portion of an air or hydraulic machine. However, such a known technique cannot be directly applied to vapor recovery.

[PROBLEMS TO BE SOLVED] Therefore, an object of the present invention is to provide a vapor recovery device capable of laterally moving a hose suspension point, in which vapor recovery hose processing is suitable and a vapor recovery operation can be performed simply as in the conventional case. In order to provide an oil supply device.

[Means for Solving the Problem] According to the present invention, the hose processing case is hung from a canopy, and a hose lead-out long hole is provided on the lower surface of the hose processing case, and the hose is provided inside the hose processing case. A carriage horizontally moving along the lead-out slot is provided with a hose reel that winds an oil supply hose and a drive motor for the hose reel, and the oil supply nozzle is provided at the tip of the oil supply hose. Is a vapor recovery nozzle and a vapor recovery refueling device having a vapor recovery hose connected to the vapor recovery nozzle, wherein the vapor recovery hose is attached to the carriage by being wound around a hanging portion of the vaporization hose,
And, it is connected to a vapor recovery pipe fixed to the hose processing case, and a curl portion is formed between the carriage and the vapor recovery pipe so as not to hinder the movement of the carriage, and A blower for sucking vapor is provided, and the recovery pipe is connected to an underground tank.

[Explanation of action and effect] Therefore, when the refueling nozzle moves up and down, the vapor recovery hose wrapped around the hanging part expands and contracts to absorb the movement, and the lateral movement of the truck causes the vapor recovery hose to move by the curl portion. It is expanded and contracted. In this way, the vapor generated during the refueling work is sucked by the blower, passes through the vapor recovery hose from the vapor recovery nozzle provided in the refueling nozzle, and from the curl section to the underground tank through the vapor recovery pipe. Be recovered.

Therefore, the vertical movement of the refueling nozzle and the lateral movement of the trolley during the refueling work can be easily performed substantially regardless of the presence or absence of the vapor recovery hose, and the refueling work efficiency does not change.

The generated vapor is sucked by a blower and collected in an underground tank, which is safe and economical.

As described above, according to the present invention, it is possible to perform a suitable vapor recovery operation in the suspension type oil supply device.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a hose processing apparatus indicated by 3 in its entirety is suspended from a canopy 1 of a gas station through suspension columns 2 and 2. The hose processing case 4 of the hose processing device 3
In the inside of the hose, there is provided a carriage 6 that is a means that can move laterally along the hose lead-out long hole 5 provided on the lower surface of the hose processing case 4. A hose accommodating portion, that is, a hose reel 7 is fixedly mounted on the carriage 6, and an oil supply hose 8 is wound and accommodated on the hose reel 7. The hose reel 7 is driven by a motor 9, and the amount of rotation of the hose reel 7, that is, the vertical position of a fueling nozzle 11 described later, can be detected by a nozzle position detector 10 that follows the hose reel 7. The downstream side of the refueling hose 8 is connected to a refueling nozzle 11 which is hung through the long hole 5 for leading out the hose.
The upstream side is connected to an underground tank 13 via an oil supply pipe 12 passing through one of the suspension columns 2. Refueling nozzle 1
1, a forward switch 26a and a reverse switch 27 are provided near
A nozzle elevating switch 26 including b is provided.
The refueling pipe 12 is provided with a pump 15 driven by a motor 14. The pump 15 sucks up oil from the underground tank 13 to the refueling hose 8 via the flow meter 16 and causes it to flow out from the refueling nozzle 11. It has become. The flow meter 16 is provided with a flow rate pulse oscillator 17, and based on the flow rate pulse output from the oscillator 17, a control device (not shown) displays a refueling amount on a display 18 provided on the wall surface of the gas station. It has become. A vapor recovery nozzle 19 is provided at the tip of the oil supply nozzle 11, and the nozzle 19 is connected to a vapor recovery hose 20. This vapor recovery hose 20 is wrapped around the hanging portion of the oil supply hose 8 in a curl shape, and is attached to the carriage 6 on the way.
The end is connected to a vapor recovery pipe 21 fixed to the inner end of the hose processing case 4. In addition,
A curl portion 22 is formed between the carriage 6 of the vapor recovery hose 20 and the vapor recovery pipe 21 so as not to hinder the lateral movement of the carriage 6. The vapor recovery pipe 21 extends upward through one suspension column 2 and is open to the atmosphere above the canopy 1. The vapor recovery pipe 21 is provided with a blower 24 driven by a motor 23.
