Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fueling device for automatically injecting fuel, for example, gasoline, into an automobile being assembled and conveyed on an automobile assembly line.

(Prior Art) Normally, in a vehicle body assembled and conveyed on a tact conveyor of an automobile assembly line, a certain amount of gasoline needs to be refueled in a fuel tank in order to drive the automobile with the line off after assembly. This refueling is automatically refueled by a refueling nozzle device of an automatic refueling device provided on the side of the refueling station to the vehicle body that has been mounted to the tire and conveyed to the refueling station in the previous step and temporarily stopped.

When this automatic refueling is performed, an error occurs in the placement accuracy of the vehicle body on the tact conveyor and the transportation stop accuracy, and an error occurs in the vertical direction of the vehicle body due to the different degree of deformation of the tires for each vehicle. Therefore, it is necessary to cope with these errors and to match the positions of the fuel supply port and the fuel supply nozzle to supply oil.

Conventionally, as this type of automatic fueling device, a positioning device has been considered in which a wheel house near the fueling port is clamped and moved from inside by three points in the front, rear, and upper parts.

When the positioning device is used, positioning of the vehicle body in the traveling direction (hereinafter referred to as front and rear) is performed by moving the vehicle body while sandwiching the wheel house from the inside to the front and rear, and positioning in the vehicle width direction (hereinafter referred to as left and right direction) is performed. Is clamped and slid on the tact conveyor. Further, the vertical positioning is performed by lifting the upper portion of the wheel house to suppress the vibration of the suspension arranged on the tire. After that, a refueling nozzle device that can be freely inserted and removed is inserted into the refueling port to refuel.

However, in this device, an excessive load is applied to the front and rear parts and the upper part of the wheel house, which is not a held part such as a jack-up point, to move and position the wheel house, which may cause damage to the vehicle body. .

(Problems to be Solved by the Present Invention) The present invention solves the conventional inconvenience and provides an automatic fueling device in an automobile assembly line capable of reliably and automatically supplying fuel without damaging the vehicle body. And

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a fueling nozzle device that can be inserted into and removed from a fueling port of a vehicle body whose transportation is stopped at a fueling station assembled and transported in an automobile assembly line. In an automatic fuel refueling device for automatically refueling, a first positioning device is provided that is detachable from and contactable with a tire near the refueling port, and holds the tire to position the refueling port in the front-rear, left-right direction. A second positioning device is provided for positioning the jack-up point of the tire held by the first positioning device in a vertical direction by raising a predetermined amount of the jack-up point of the tire.

(Operation) According to such means, in the automatic fueling device in the automobile assembly line of the present invention, the vehicle body stops being conveyed at the fueling station, and the tire near the fueling port of the vehicle body is clamped by the first positioning device. Then, the fuel filling port is guided to a predetermined position in the front-rear, left-right direction. Next, the vehicle body is
The positioning device lifts the jack portion of the tire portion by a predetermined amount. At this time, since the tires are sandwiched between the vehicle body, only the body near the tires is lifted and the fuel filler is positioned and fixed in the vertical direction. Then, the refueling nozzle device is inserted into the refueling port to inject fuel into the fuel tank.

When the vehicle body X is conveyed to the set stop position by the tact conveyor, the moving cylinder (not shown) is driven to move the first table 4 and the second table machine frame 7 to the predetermined position shown in the first figure. The position cap Y to lower the cap attachment device B ₂ by a cap feeder C is supplied with, receives the cap Y by a cap attachment apparatus B ₂ is lowered by the lifting device 40 is raised to a predetermined position.

At the same time, the first cylinder 24 of the first positioning device 8 is driven to move the front tire clamp arm 13 rearward so that the second rack 21 is moved rearward. As a result, the pinion 19 is rotated clockwise in the drawing, and the first rack
20 is moved forward, the rear tire clamp arm 13 is moved forward, and the front and rear tire clamp arms 13,
The 13 are moved toward each other by moving forward and backward.
At this time, the tire W in the vicinity of the fuel supply port, which is stopped with an error at the predetermined stop position, has the inner inclined surface 15 of the clamp portions 14, 14.
The vehicle body X is pinched while being guided along with the positioning of the vehicle body X in the front-rear direction and the left-right direction, and accordingly, the fuel filler port Z is positioned in the front-rear direction and the left-right direction.

Due to the movement of the second table machine frame 7, the lifter lever 27 of the second positioning device 9 reaches below the jack-up point of the tire W. Next, the second cylinder 30 of the second positioning device 9 is driven while the tire W is clamped, and the lifter lever 27 is used as the fulcrum of the support pin 25 to form the joint member 29.
Swing through. The vehicle body X lifts the jack-up point of the tire W in the vicinity of the filler port by the swinging of the lifter lever 27, and swings with another tire as a fulcrum, and only the body of the vehicle body X in the vicinity of the filler port is raised and held at a predetermined position. It Therefore, after positioning the vehicle body X in the front-rear and left-right directions, only the body of the vehicle body X is raised to a predetermined position and positioned, so that the refueling port Z is positioned in the front-rear, left-right and up-down directions, and the vehicle body X is held in this state. To be done.

While the vehicle body X is being positioned, the third table 35 is retracted on the second table machine frame 7 to a predetermined position. Then, after the positioning of the fuel filler Z, the fuel filler nozzle device B ₁ and the cap mounting device B _{2 are} swung at the predetermined position, and the fuel filler nozzle device B ₁ is inserted into the fuel filler port Z in an inclined state due to this swing. Refuel gasoline as fuel. Next, the cap mounting device B ₂ is moved to a position facing the fuel filler port Z by the fourth table 38, and the fuel filler port Z is closed by the cap Y held by the cap mounting device B ₂ .

Further, in the present embodiment, when changing the carrying position of the vehicle body X, the second table machine frame 7 is moved along the adjust rail 5 by a cylinder (not shown), and then the third table 36 is moved.
By moving the vehicle to a predetermined position and adjusting the distance between the tire and the refueling port, it is possible to refuel even different vehicle types.

(Effects) As is apparent from the above description, the present invention holds the deformable tire between the first positioning device for positioning in the front-rear, left-right direction, and the second positioning device to set the jack-up point of the tire. Provided is an automatic fueling apparatus for an automobile assembly line, which can reliably and automatically lubricate a vehicle body without damaging the vehicle body because the vehicle body is held in a state where the fueling port is positioned by lifting and positioning in the vertical direction. can do.
