Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device for refueling a lorry.

As is already known, a lorry stops at the side of a refueling device stand called a rack, and refuels by inserting the refueling nozzle of the loading arm of the refueling device into the refueling port of the hatch of the lorry.
The lorry is usually divided into hatches of about 2Kl, and the loading arm's refueling nozzle must be sequentially inserted into the refueling port of each hatch depending on the oil type or oil quantity. Inserting and removing the arm's refueling nozzle is quite troublesome.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lorry oil supply device that can automatically move a refueling nozzle to a lorry hatch refueling port.

According to the present invention, in a refueling device for refueling a lorry, first and second refueling pipes extending horizontally to the lower part of a canopy are connected via a swivel joint, and the first refueling pipe is connected to a flow meter. The second oil supply pipe is horizontally rotatably connected to a pipe extending from the refueling unit, and the second oil supply pipe is horizontally rotatably connected to a telescoping pipe provided in a refueling unit. A refueling nozzle is provided at the tip of the telescoping tube, and the refueling unit is provided with a lorry lid opening/closing device and a sensor, and the refueling unit is moved in the traveling direction of the lorry and in a perpendicular direction. A detected part is provided near the refueling port of the hatch of the lorry, and the position of the refueling unit is controlled by a signal from the sensor that detects the detected part.

Therefore, when the lorry is stopped at a predetermined position, the first and second oil supply pipes, which are pivoted to each other in the horizontal direction, move in the direction in which the lorry travels (hereinafter referred to as the X direction) and in the direction perpendicular thereto (hereinafter referred to as the Y direction). )
The refueling unit can be moved to
-Move in the Y direction.

In this way, the refueling unit can be moved in the X-Y direction and positioned above the hatch of the lorry, and the refueling nozzle can be inserted into the hatch, thus eliminating the need to work above the lorry where footing is difficult. .

The above refueling work can be performed using a sensor.

Prior to refueling, the sensor detects the lid of the lorry's hatch, and the lid opening/closing device opens the lid. This lid opening/closing device may be one suitable for opening and closing the lid of the hatch; for example, if the lid is screw-fitted, a device that engages with the lid and rotates may be used. As described above, according to the present invention, the lorry can be automatically refueled without moving the lorry.
Workers are safe because they do not have to work on dangerous lorries.

In carrying out the present invention, any known means can be used as the moving means; for example, the refueling unit can be moved along a horizontal bar extending in the lateral (Y direction) direction using a screw and a pulse motor; In addition, the horizontal bar may be moved in the perpendicular direction (X direction) using a chain or the like.

Furthermore, since the lorry driver (worker) usually has a card containing lorry data, the lorry can be controlled in a known positioning manner based on the card.

A refueling start signal is then transmitted from the control circuit 48 to the control circuit 50, and the control valve 8b is opened in response to the signal from the third control circuit 50, and the refueling operation is performed. The flow rate signal from the flowmeter 9b is sent to the third control circuit 50, and when a predetermined amount of oil is reached, the control valve 8b is closed, the oil supply nozzle 32b is retracted, and a signal indicating the end of oil supply to the first hatch is sent to the control circuit 50. The signal is then transmitted to the control circuit 48. Then, the fuel supply unit 16 moves in the X and Y directions so that the lid opening/closing device 38 is located above the fuel filler port 17a, and the fuel filler port 17a is covered.

When the above operations are completed, the refueling unit 16 is moved in the direction of the next hatch, for example, the hatch 18b, and the above operations are repeated.

When all the predetermined lubrication operations are completed in this way, the lubrication data is printed by the printer 5 and a slip 60 is issued. Next, the driver disconnects the ground wire 40 and starts the vehicle.

As described above, according to the present invention, once the lorry is stopped at a predetermined position, grounded, and the card is inserted into the card reader, the refueling nozzle of each oil type will be automatically activated one after another by simply pressing the start button. Since the refueling operation is carried out by moving to the refueling port, the troublesome operation of operating the loading arm is unnecessary, making the refueling operation extremely easy.
