Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a rust-preventive oil application device for automobiles that sprays and coats rust-preventive oil onto the underside of an automobile that has been assembled through the automobile manufacturing process.

[Prior art and its problems]

Once assembled, a finished car has its body surface coated with wax to protect the painted surface, and its underbody coated with anti-rust oil before being shipped.

By the way, in a car production line where cars are continuously transferred one after another by a conveyor,
It is desirable to apply anti-corrosion oil to a fully assembled automobile while continuously transporting it.

However, the underside of the car that needs to be coated with anti-corrosion oil has a wheel suspension system with a complicated shape, so while transporting the car, apply rust-preventive oil to the entire suspension system and the underside of the floor. Spraying is a very difficult task.

In particular, since anti-corrosion oil must not leave any residue, it has been virtually impossible to apply it to the undercarriage of automobiles that are transported at the same speed as the line speed of the automobile manufacturing process.

For this reason, in the past, the process of applying anti-corrosion oil was unavoidably carried out outside the conveyor line of the automobile manufacturing process, and cars that had been assembled and removed from the manufacturing process were manually transported to the area where the anti-rust oil was sprayed. The anti-rust oil is then sprayed using a reciprocating applicator towards the underside of the vehicle stopped at the spraying location.

However, if the reciprocating applicator is simply moved back and forth toward the underside of the car, rust preventive oil will be sprayed on areas that should not be coated with rust preventive oil, such as the tires on the wheels. The work of wiping it off was difficult. In particular, when applying the anti-rust oil around the spare tire installed on the underside of the floor, it was unavoidable that the anti-rust oil would adhere to the spare tire. In addition, normal reciprocating coating machines
It is not possible to thoroughly apply anti-rust oil to the back of the front and rear ends of a car or to the suspension system, which has a complicated shape, and it is extremely difficult to spray anti-rust oil onto the entire undercarriage without leaving any residue. Complicated mechanisms and controls are required to perform complex operations.

[Means for solving problems]

Therefore, the present invention uses an extremely simple mechanism and control to thoroughly apply rust preventive oil to the entire undercarriage of a car that is continuously transferred, and also reliably prevents rust preventive oil from adhering to spare tires, etc. The purpose of the present invention is to provide a rust preventive oil application device, and in order to achieve this purpose, a first underfloor applicator that sprays rust preventive oil onto the underside of a car's floor, and a suspension system for left and right wheels of a car are provided. a pair of suspension system applicators that spray anti-corrosion oil on the respective parts, and a second floor applicator that sprays anti-rust oil onto the back of the floor around the spare tire left uncoated by the first floor applicator. are arranged in a row along the underfloor where the automobile is transported, and the first underfloor coating machine is disposed opposite to the underfloor of the automobile,
The applicator for each suspension system is configured to be rotatable back and forth along the transport direction of the vehicle so as to spray anti-rust oil on the back surfaces of the front end and rear end of the vehicle. The anti-corrosion oil is disposed facing the suspension device at a fixed angle on the front side or the rear side thereof, and is configured to be able to rotate in the horizontal direction, and is configured to spray anti-rust oil from both the front and rear sides of the suspension device. Further, the second floor coater is configured to spray anti-corrosion oil toward the floor from behind a masking plate for masking a spare tire mounted on the back of the automobile. It is characterized by the presence of

[Effect]

According to the present invention, the first floor coating machine is first rotated so as to face the back surface of the front end of the vehicle being transferred, sprays rust preventive oil onto the back surface of the front end, and then Rotate it so that it faces the back of the floor and spray anti-rust oil on the back of the floor. and,
When the back of the floor equipped with the spare tire arrives, the spraying of rust preventive oil by the applicator is temporarily stopped, and when the spare tire passes, spraying of the rust preventive oil is resumed, and the applicator is moved to the rear end of the vehicle. Rotate it so that it faces the back side, and spray anti-rust oil on the back side of the rear end.

In addition, each suspension system applicator first faces the front side of the suspension system and sprays the anti-rust oil from the front side of the suspension system, and when the spraying is finished, it rotates to the rear side of the suspension system. Spray anti-rust oil from the rear side of the suspension system.

In addition, when the spare tire installed on the underside of the automobile reaches a position where it is to be masked by the masking plate, the second floor coating machine moves toward the underfloor from behind the masking plate. Spray rust preventive oil and apply the rust preventive oil to the back of the floor around the spare tire left uncoated by the first floor coater.

As a result, the rust preventive oil is thoroughly applied to the entire underside of the car, such as the underside of the floor and the suspension system, which is being transported continuously, and the rust preventive oil is also prevented from adhering to the spare tire, etc. .

The motor vehicle M is configured to be rotatable back and forth along the transport direction F of the motor vehicle M by the rotation of the rotary shaft 7.
Antirust oil is also sprayed onto the back surfaces of the front end _A1 and the rear end _A2 .

A rotary shaft 7 that rotates these applicators 1a, 1b back and forth has a pinion 11 fixed at one end that meshes with a rack gear 10 that is connected to a double-headed cylinder 9 and moves linearly back and forth. By extending and contracting both piston rods at the same time or by extending and contracting only one of them, the piston rod can be rotated in three stages at a constant rotation angle.

Further, each suspension device coating machine 3R, 3L has an angle adjustment rod 14 attached to a position adjustment bracket 13 attached to a vertical rotating shaft 12R, 12L, respectively.
It is attached to each suspension unit B of the left and right wheels 2R, 2L at a fixed angle from the front side or the rear side, and supports the lower end of each rotating shaft 12R, 12L. The pinions 15R and 15L are engaged with a two-pronged rack gear 17 that is connected to the cylinder 16 for linear reciprocating motion, and the piston rod of the cylinder 16 is expanded and contracted with a constant stroke to rotate in the horizontal direction at a constant rotation angle. Then, antirust oil is sprayed onto both the front and rear sides of each suspension unit B.

Furthermore, the second floor coater 5a, 5b sprays antirust oil toward the floor back A from behind the masking plate 18 that masks the spare tire 4 installed on the floor back A of the automobile M. It is done like this. Each applicator 5a, 5b is attached via an angle adjustment rod 21 to a position adjustment bracket 20 attached to a bracket mount 19, 19 fixed vertically at regular intervals in the width direction of the floor back part A. There is. Further, the masking plate 18 is connected to the spare tire 4.
The cylinder 2 is formed into a shape surrounding the cylinder 2.

It is designed to advance and retreat from below.

In the figure, 23R and 23L are applicators that spray antirust oil along the back surface of the left and right end portions of the automobile M.

Therefore, when applying anti-rust oil to the underside of the automobile M while transporting it, the distance between the first floor coating machines 1a and 1b is adjusted in advance, and the coating width of the coating machines 1a and 1b is adjusted in advance. is set to match the width of the back floor A of the car M, and when the car M is transferred, both the left and right piston rods of the cylinder 9 are simultaneously contracted, and each coating machine 1a, 1b is set to the width of the back of the car M. Rotate it so that it faces the back surface of the front end portion A ₁ and spray rust preventive oil on the back surface of the front end portion A ₁ .
Next, when the anti-rust oil is applied to the back surface of the front end _A1 , only the left and right piston rods of the cylinder 9 are extended, and each applicator 1a, 1b is moved to the back floor area A of the automobile M as shown by the solid line in FIG. Rotate it so that it faces the floor, and spray anti-corrosion oil toward the back of the floor A.

Then, when the back floor area A equipped with the spare tire 4 arrives, the spraying of rust preventive oil by the applicators 1a and 1b is temporarily stopped, and when the spare tire 4 passes, the spraying of the rust preventive oil is started again. , the piston rod on the left side of the cylinder 9 is also extended, and each applicator 1a, 1b is rotated so as to face the back surface of the rear end portion _A2 of the automobile M, so that the rust preventive coating is applied to the back surface of the rear end portion _A2 . Spray with oil.

As a result, the anti-corrosion oil is applied to the _entire surface of the back of the car M except for the area around the spare tire 4 installed in the back of the car. Antirust oil is also applied to the back surface of the rear end _A2 .

In addition, the installation positions and installation angles of the suspension applicators 3R and 3L are adjusted in advance so that the rust preventive oil is sprayed only on the suspension parts B of the left and right wheels 2R and 2L, respectively. When part B arrives, first, with the piston rod of the cylinder 16 extended, rust preventive oil is sprayed from the front side of each suspension part B, and when the spraying is finished, the piston rod of the cylinder 16 is The piston rod contracts and turns to the rear side of each suspension section B, and the antirust oil is sprayed from the rear side of the suspension section B.

As a result, each suspension system part B has a complicated shape.
Anti-rust oil is thoroughly applied to both the front and rear surfaces of the
Left and right wheels 2R and 2L must not be coated with anti-rust oil
This prevents rust preventive oil from adhering to the tire surface.

In addition, when a spare tire 4 installed on the underfloor part A of the automobile M arrives, the second floor coating machines 5a and 5b are arranged so that a masking plate 18 for masking the spare tire 4 is applied to the spare tire by a cylinder 22. At the same time as the tires are advanced in four directions, the masking plate 18
The rust preventive oil is sprayed from behind toward the floor back part A, and the rust preventive oil is applied to the floor back part A around the spare tire 4 left uncoated by the first floor coaters 1a and 1b.

Thereby, it is possible to prevent the rust preventive oil from adhering to the surface of the spare tire 4, which should not be coated with rust preventive oil, and to thoroughly apply the rust preventive oil to the entire underfloor part A of the automobile M.

Furthermore, as in the embodiment, there is a coating machine 23R that sprays anti-corrosion oil along the back surface of the left and right end portions of the automobile M;
If 23L is provided, the rust preventive oil can be almost completely applied to the entire lower part of the automobile M.

Note that the first floor coating machines 1a, 1b, the suspension device coating machines 3R, 3L, and the second floor coating machines 5a, 5b may be arranged in random order.

[Effect of idea]

As described above, according to the present invention, the underbody of a car to be coated with anti-corrosion oil is divided into the floor area and the suspension system, and the anti-rust oil is sprayed onto each part using a dedicated applicator. Because of this, each applicator with an extremely simple mechanism and control has the advantage of being able to thoroughly apply anti-corrosion oil to the entire undercarriage of a continuously transported vehicle, while reliably avoiding spare tires, etc. It has a positive effect.

In other words, a first and second floor coating machine is provided specifically for the back of the floor, and these machines apply anti-rust oil to the entire back of the floor, excluding the area around the spare tire, and to the back of the front and rear ends of the car. The first floor coating machine that sprays is
A simple mechanism and control that rotates this back and forth at a predetermined timing and turns on and off the anti-rust oil is sufficient.Also, you can mask the spare tire and apply anti-rust oil to the underside of the floor around it. The second floor coating machine that sprays requires an extremely simple mechanism and control that simply turns the rust preventive oil on and off at predetermined timings. Furthermore, the suspension applicator dedicated to the suspension system is also extremely easy to use, as it rotates to alternately face the front and rear sides of each suspension system at predetermined timings, and turns the anti-rust oil on and off. A simple mechanism and control is sufficient, and it sprays rust preventive oil from both the front and back sides of the suspension system, which is difficult to spray with a reciprocating device, and allows the rust preventive oil to be applied to the entire complex-shaped suspension system without leaving any residue. There is an excellent effect that can be done.
