Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device, and more particularly to a hose-suspended refueling device in which a card reader is provided on a nozzle or a hose near the nozzle.

Conventionally, a card reader is installed on the hose near the nozzle, and customers have their own card read by the card reader. If the card is a genuine card, the card is refueled and information such as the amount of oil, oil type, price, date, etc. The refueling element and the card element are recorded in a recording device, and the refueling element and the card element are printed on a slip and issued (for an example, see Japanese Utility Model Publication No. 49-43597).

By the way, this type of conventional refueling system has been installed from the hose raised position (approximately 3.5 m above the ground where large vehicles such as trucks can pass) to the hose standby position (approximately 3.5 m above the ground where the nozzle can be reached) when the store opens. 1.8m
When a customer comes and presses the hose lowering switch, the hose will be lowered directly from the hose standby position to the refueling position (lower position near 0m where refueling is possible). At the hose standby position, the nozzle can be reached, but the card reader cannot be operated, so the hose must be lowered to the refueling position before operating the card reader. In this position, since the nozzle is held with one hand, the card operation must be performed with one hand, making it difficult to operate, and the position of the card reader is too low, making it difficult to operate.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional refueling device of this type.
Normally, the hose is stopped at a height of about 1.5 m above the ground, and the card reader is easily read by holding the card reader with one hand and inserting the card into the card reader with the other hand. This is how it was done.

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

FIG. 1 shows the entire structure of a hose hanging type refueling apparatus according to the present invention, in which a hose storage box 1 is suspended from the ceiling of a refueling station, and a hose 2 is stored in this storage box 1. A pipe 3 is connected to the base end of the hose 2 and communicates with an underground tank (not shown). A pump motor 4 and a flow meter 5 are provided in the middle of the pipe 3. The hose storage box 1 is equipped with a hose motor 6 and a cam switch 7. When the hose motor 6 rotates forward or backward, the hose 2 is raised or lowered, and when the cam switch 7 opens, the hose motor 6 stops and the hose is removed. 2 automatically stops at a predetermined position.

A nozzle 8 is attached to the tip of the hose 2, and near the nozzle 8, the hose 2 is provided with a card reader 9 and a hose up switch 10 and a hose down switch 11, which are hand switches. A string 12 for opening and closing the switch hangs down from the hose lowering switch 11.

At the wall of the gas station, move the hose 2 from raised position A (approximately 3.5 m above the ground) to standby position B (approximately 1.8 m above the ground), or from standby position B to raised position A. A hose up switch 13 and a hose down switch 14 are provided to raise or lower the hose. Furthermore, an indicator 15 with a card reading lamp 16 is installed at an easily visible position on the wall of the gas station.
The signal from the flowmeter 5 is input to the flowmeter 5.

In addition, C is the card reading position (approximately 1.5 from the ground)
m height position) D indicates the refueling position (0 m position). Furthermore, in the illustrated example, the card reader 9 is attached to the hose 2 in contact with the nozzle 8;
It may be attached to the nozzle 8, or it may be attached to the hose 2 at a position somewhat distant from the nozzle 8.

FIGS. 2 and 3 show an example of a control circuit used in the oil supply system of the present invention, and the operation of the oil supply system of the present invention will be explained with reference to this control circuit and FIG. 1.

When the hose lowering switch S ₁ (shown as switch 14 in Figure 1) near the wall is pressed when opening the store, relay R ₁ is activated, closing its contacts R ₁ ′ and R ₁ ″ and opening contact R _1. Contact R ₁ ′ is self-retained by contact R ₁
Prevents malfunction by opening. contact
When R ₁ '' is closed, the hose motor M6 rotates forward and the hose 2 is lowered from the hose raising position A. When the hose 2 is lowered to the standby position B, the cam switch CS ₁ is activated.
7 opens, relay _R1 is deenergized, hose motor M6 is stopped, and hose 2 stops descending. In this state, wait for customers to arrive.

When a customer comes and pulls the hose lowering string 12, the hose lowering switch S ₂ 11 closes, and the relay R ₂ operates, closing its contacts R ₂ ′ and R ₂ ″ and opening the contact R ₂ . It is self-held by the contact R ₂ ′. , contact R ₂ opens to prevent malfunction. When contact R ₂ '' closes, the hose motor M6 rotates forward and the hose 2 is lowered from the hose standby position B. When the hose 2 descends to the card reading position C, the cam switch CS ₂ 7 opens, the relay R ₂ is deenergized, the hose motor M6 stops, and the hose 2 stops descending.

At this card reading position C, the worker or customer inserts the customer's card into the card reader 9,
The card is read by the card reader 9. At that time, the card reader 9 is located approximately 1.5 m above the ground, making it easy to read the card by holding the card reader 9 with one hand and inserting the card into the card reader 9 with the other hand. . If the card is genuine, card reading switch S ₃ closes and relay R ₃ operates, its contacts R ₃ ′, R ₃ ″,
R ₃ closes and contact R ₃ 〓 opens. It is self-held by contact R ₃ ′, and malfunction is prevented by opening contact R ₃ 〓. Contact _R3 closes, the card reading lamp L16 on the display meter 15 lights up, and the previous oil supply amount on the display meter 15 is returned to zero, and the pump motor
PM4 rotates and becomes ready for refueling. Also relay
R ₄ acts and its contact R ₄ ′ closes and is self-maintained.
Contact _R3 closes, hose motor M6 rotates forward, and hose 2 descends from card reading position C. When hose 2 descends to the refueling position D, the cam switch
CS ₃ opens, relay R ₃ deenergizes, hose motor M6 stops, and hose 2 stops descending.

When refueling is performed, the amount of refueling is displayed on the display meter 15 by a signal from the flowmeter 5, and the refueling element and card element are recorded on the recording device and printed on the slip.

When refueling is finished and hose lift switch S ₄ 10 is closed, relay R ₅ is activated and its contacts R ₅ ′ and R ₅ ″ are closed.
_R5 opens. It is self-held by contact R ₅ ′, and malfunction is prevented by opening contact R ₅ , and relay R ₄ is deenergized to disable refueling. When contact _R5 '' closes, hose motor M6 reverses and hose 2 rises.When the hose reaches standby position B, cam switch _CS17 opens, relay _R5 is deenergized, hose motor M6 stops, and hose 2 rises. The rise stops.

When the hose lift switch S ₅ 13 near the wall is closed when the store is closed or at a gas station where many large vehicles such as trucks come, the relay R ₆ is activated, closing its contacts R ₆ ′ and R ₆ ″ and opening the contact R ₆ . It is self-retained by contact R ₆ ′, and malfunction is prevented by opening contact R ₆ ″. When contact R ₆ ″ closes, hose motor M6
is reversed, hose 2 rises, and the hose rises to position A.
When this happens, cam switch CS ₄ 7 opens, relay R ₆ de-energizes, and hose motor M 6 stops.

As explained above, in the present invention, the hose is stopped at a card reading position where it is easy to operate the card reader during the process of lowering the hose, so you can hold the card reader with one hand and read the card with the other hand. Since the card can be inserted into a reader, reading the card becomes very easy, and refueling work can be carried out efficiently.
