Description

  The present invention relates to an apparatus for polishing and coating paint used in vehicles and the like, and more particularly to an apparatus for automatically polishing and coating on the curved surfaces of side surfaces and four corners.

The actual grounding work during painting and coating work after painting are usually performed manually by the operator using buffs and sponges attached to an electric poly-render and using the rotational force of the electric motor. It is.
It is understood that the paint industry has a reason that the labor saving due to mechanization is greatly delayed due to the craftsmanship that requires skill.

  In addition, a semi-automatic polishing apparatus by the present inventor has utility model registration No. 3065403 (provided by evaluation 6 without prior art in the request for evaluation), and the present invention further advances the current polishing and coating work. It is something to be made.

Problems to be solved by the invention

In polishing and coating work for vehicles and the like, it is known that moving the polisher at a constant pressure and a constant speed has a significant effect on the quality of the finished surface, but development has been done to achieve this. Was not.
This is because polishing and coating work is a craftsmanship and there was great resistance to accepting the introduction of machines.

  The present invention has been made in view of such problems of the prior art, and by using a polisher at a constant pressure and a constant speed, polishing work and coating work of a paint surface applied to a vehicle or the like can be performed. By mechanization, the purpose is to improve work efficiency, simplify work, and improve the brightness of the painted surface.

Means for solving the problem

  Automatic side polishing in which a vertical moving unit 2 is provided above the side moving unit 1, a horizontal moving transfer unit 3 is provided in the vertical moving unit, and an elastic body 5 for attaching a polisher is provided at an end of the horizontal moving unit. Machine.

  In the side surface moving unit 1, a drive wheel 12 driven by a motor with a variable speed function is provided at a substantially central portion of a side surface portion of the machine base 11, and free wheels 13 and 14 are provided at two locations on the opposite side surface portions. Automatic side polishing machine.

  This is an automatic side polishing machine provided with a pressure adjusting unit 4 for applying a variable biasing force to the horizontal moving unit with an electric polisher attached to the end of the horizontal moving unit.

The invention's effect

  The painting coating work concentrates the nerves on reciprocating the painted surface with equal force, so most of the work relied on the skill of the operator, but using the device of the present invention, the work This not only reduces the fatigue of the workers, but also improves the efficiency of the work itself. This is because work always proceeds at a constant speed regardless of the operator's intention.

  The conventional polishing and coating work that required craftsmanship succeeded in simplifying the work by transforming it into work management and confirmation work by realizing constant pressure and constant speed.

  In addition, the coating work on the painted surface was made constant pressure and constant speed, which improved the radiance, which is a finished surface that is comparable to craftsmanship. That is, it is judged as an achievement that overcomes the difficulty of always moving the electric polisher at a constant pressure and a constant speed.

  By providing two universal wheels, it became possible to move in a circle around the drive wheel, so it was possible to work on curved surfaces at the four corners of the vehicle. In addition, it is easy to change the direction and improves work efficiency.

  The side surface moving unit 1 has good performance even in a four-wheel vehicle, a caterpillar driving vehicle, etc., but one driving wheel is provided at the center of the side surface and two universal wheels are provided on the other side surface. This is the best mode. Moreover, it is necessary for the movement in the side direction to have a speed variable function. This is because the working speed differs depending on each worker, and the polishing and coating work has a feature that requires a fine speed adjusting function.

  The vertical movement unit 2 drives the shaft 22 by the motor 21 to move the fixed unit (the portion to which the horizontal movement unit is attached, not shown) up and down, and the best result is obtained, but the linear guide and the brake mechanism Good results are obtained even in combination.

The horizontal moving part 3 is provided with a rack 31 at the lower part of the linear guide, a pinion and a handle 32 are provided at a fixed part (not shown) that moves via a bearing, and the pinion is rotated and meshed with the rack 31 when the handle is rotated. The structure in which the linear guide moves in the horizontal direction around the handle is the best mode.
Furthermore, providing a shopper mechanism (not shown) for stopping the feeding of the linear guide of the horizontal moving unit 3 constitutes a function indispensable for actual work.

  The pressure adjusting unit 4 is a part that uses the weight of the weight to urge the horizontal moving part in the horizontal direction, and the electric polisher applies a pressing force to the painted surface. The pressing force can be adjusted. Also, good results can be obtained by a method using contraction force utilizing elasticity such as a spring.

  The elastic body 5 is provided to absorb vibration from the electric pusher and uses a synthetic resin rubber body. However, it is important to have an appropriate hardness (a degree that does not deform due to the weight of the electric polisher). Yes, as long as this is satisfied, an impact absorbing mechanism using natural rubber, hard synthetic resin, or a mechanism can be sufficiently used.

Hereinafter, embodiments of the present invention will be exemplarily described in detail with reference to the drawings.
However, the construction method, construction device, construction content, construction parts, dimensions, material, shape, relative arrangement, etc. described in this embodiment are within the scope of the present invention unless otherwise specified. It is not a thing intended to limit only to them, but merely an illustrative example.

In FIG. 1, wheels 13 and 14 are provided in the longitudinal direction of the machine base 11, a motor 15 is disposed at a position opposite to the wheels, and a drive wheel 12 is attached to a drive shaft of the motor. Or, the limit switches 61 and 62 reciprocate.
Further, in the bottom view shown in FIG. 4, by providing the wheels 13 and 14 with free wheels, not only can the direction be changed easily during driving, but also the coating work can be performed on the curved surfaces at the four corners of the vehicle.

  As shown in FIG. 2, the vertical movement unit 2 has a structure in which the screw 21 in the vertical movement unit is rotated by the upper motor 21 to move the horizontal movement unit 3 up and down.

An electric polisher 7 is attached to the end of the horizontal moving part 3 via an elastic body 5. When a linear guide is used for the horizontal moving part, the electric polisher 7 is horizontally moved by operating the handle 32. It is a structure that moves in the direction.
That is, as shown in FIG. 2, a rack gear is provided at the lower part of the linear guide 3 and a pinion gear is provided on the handle shaft so that when the handle is rotated, the pinion gear is also rotated and the rack gear is moved and moved. Thus, the horizontal moving part moves.

Further, the pressure adjusting unit 4 is provided in the horizontal moving unit. In FIG. 2, the weight of the weight is used to press the polisher 7 in the side direction with an appropriate force.
In other words, the electric polisher 7 provided at the end of the horizontal moving portion is a mechanism that can be driven by both the pressure adjusting means 4 and the handle 32.

  When this apparatus is operated in the automatic mode, the buff of the electric polisher 7 is moved to the side while rotating with an appropriate force (about 5 kg), and then the motor 21 of the vertical movement unit is driven so that the buff width of the polisher is the same. After moving in the up and down direction, the motor 15 of the side moving unit rotates again to drive the wheels 12 to move the machine base in the side direction, and alternately repeats the vertical direction movement and the side direction movement, Is the way to finish.

  In the automatic mode, the control unit 6 that controls the overall movement detects the electrical signal from the side movement detection limit switches 61 and 62 and controls the machine base 11 to reciprocate. Next, the control unit that has detected the electrical signals from the vertical movement detection limit switches 23 and 24 rotates the shaft 22 with the motor 21 to move the horizontal moving unit 3 in the vertical direction, and the electric polisher 7 is moved. The vehicle side is uniformly ground and coated at regular intervals.

  The reciprocating movement in the manual mode can be switched between the reciprocating movements of the side by operating the forward / backward switch (not shown in the drawing), and the vertical movement can be moved horizontally by operating the vertical movement switch (not shown in the drawing). The part can be moved up and down.

  When the polishing and coating work at the four corners is described with reference to FIG. 4, the locking mechanism (not shown in the figure) of the free wheels 13 and 14 is released and a force is applied to the machine base 11 as a free wheel. Since the machine moves so as to draw the rotation locus (b) around a), the polishing and coating work at the four corners can be performed continuously.
