[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic coating device used for coating outer panels of ships.

[0002]

[Prior art]

 Heretofore, it has been a general practice to manually coat a side outer panel of a ship or the like on a coating surface 14 by mainly using a coating spray 06 as shown in FIG.

As a mechanical version of this, for example, there is one in which a reciprocating motion of a chain 07 which is endlessly rotated by a motor 15 as shown in FIG. 6 is utilized and a coating spray 06 is combined with this.

On the other hand, various multifunctional robots using precision equipment have been developed, but none of them are indoor specifications and have not been used outdoors.

[0005]

[Problems to be solved by the device]

 The above-mentioned conventional coating means has the following problems to be solved.

That is, when the manual work of FIG. 5 is performed, there are the following problems (1) to (3).

(1) When painting a wide area, it is a heavy work because it requires a long work time.

(2) When coating a wide area, it is difficult to coat uniformly.

(3) Due to the above-mentioned difficulties, the work requires a high degree of skill and patience.

Further, the conventional automatic coating machine as shown in FIG. 6 has the following problems (4) to (7).

(4) Since a mechanism that is fairly heavy in weight reciprocates, if this is mounted at the tip of the running scaffold, the arms of the scaffold vibrate and the coating becomes uneven, resulting in poor quality. Will be

(5) Mechanically complicated and difficult to maintain.

(6) It is expensive in terms of price.

(7) In the case of a multi-function robot, it hinders its outdoor use.

An object of the present invention is to provide a mechanically simple, lightweight and inexpensive automatic coating device which solves these problems.

[0016]

[Means for Solving the Problems]

 Means for Solving the Problems The present invention is, as a means for solving the above-mentioned problems, a crank which is mounted on a pedestal provided in the vicinity of a painted surface and which is pivotally supported at its base end side on a first fulcrum on a line substantially perpendicular to the painted surface, and The base end side is pivotally supported by a second fulcrum closer to the painted surface than the first fulcrum on a vertical line, and the middle part is slidably connected to the tip end side of the crank so that it swings in response to the rotation of the crank. The movable link is connected to the base end side so that it can slide for a required distance on a line vertical to the side farther from the first fulcrum on the vertical line to the painting surface. Provided is an automatic coating device characterized by comprising a slider crank, the middle of which is pin-connected to the tip end side of the link, and the tip end side swings while sliding the base end side according to the swing of the link. It is what

[0017]

[Action]

 Since the present invention is constructed as described above, it has the following effects.

That is, the crank which rotates with the first fulcrum on a line substantially vertical to the painted surface of the pedestal as a pivot, and the base end side on the second fulcrum closer to the painted surface than the first fulcrum on the vertical line. Since a pivot is provided and the middle part is slidably connected to the tip side of the crank and swings according to the rotation of the crank, the link swings symmetrically with the vertical line as the center line by the rotation of the crank. . At that time, since the link swings instead of rotating, it has a posture facing the crank, and is on the side farther from the painted surface when viewed from the second fulcrum.

Next, the base end is connected to the side perpendicular to the painted surface on the side distant from the first fulcrum on the vertical line so as to be slidable by a required distance, and the tip end side is provided with a paint sprayer to face the painted surface, and Since a slider crank that is pin-connected to the tip side of the link is provided in the middle, the link swings when the crank rotates, and the slider crank pin-connected to the link tip swings. At that time, since the slider crank swings instead of rotating, the slider crank is in a position facing the link, and the coating spray swings in a posture facing the coating surface.

Therefore, when the paint is sprayed from the coating spray, the coating surface (surface to be coated) is coated over the swing range of the coating spray.

At that time, the slider crank is not merely rocked, but is rocked on the base end side far from the painted surface while sliding for a required distance on a line substantially perpendicular to the painted surface, so that the slider crank is at the rocking center. At a position where the slider crank reaches the vertical line, the base end side of the slider crank slides to the position farthest from the painted surface. When the arcs to be drawn are too close to each other, they are swung while moving in a direction away from the painting surface due to sliding, so the proximity due to the shaking and the separation due to the sliding cancel each other out, and the distance between the painting surface and the tip of the coating spray fluctuates. Is small and uneven coating does not occur.

Since the pedestal may move freely, for example, if a pedestal is moved in a direction perpendicular to the rocking surface of the coating spray, a large painted surface can be automatically painted.

By the way, referring to FIG. 4 which is a schematic view of FIG. 1 of the embodiment, the above-mentioned operation will be visually described below again.

In FIG. 4, at the tip of the coating spray 6, the position where the pin 10 is the highest is P1, the position where the pin 10 is horizontal is P2 and P4, and the position where the pin 10 is the lowest is P3. At this time, if each element constituting the mechanism is set such that P1 to P4 are linear, the coating surface 14 is coated by the linear reciprocating motion.

By combining this reciprocating automatic coating machine with a self-propelled scaffold that moves in a direction perpendicular to the reciprocating direction, continuous coating with a constant width becomes possible. The reference numerals, the explanations of which are omitted, are the same as those in FIG. 1 of the embodiment.

[0026]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. The same structural members as those in the conventional example are designated by the same reference numerals, and the description thereof will be omitted unless necessary.

FIG. 1 is a side view of this embodiment, FIG. 2 is a plan view thereof, and FIG. 3 is an explanatory view sequentially showing in side view the operation of this embodiment, that is, the swinging state of the coating spray 6 and the like. In the figure, (a) shows the case where the coating spray 6 is at the uppermost end of the swing, (b) shows the case at the center of the swing, and (c) shows the case at the lowermost end of the swing. is there. Note that P1 to P3 in FIG. 3 correspond to the same symbols in FIG.

In FIG. 1, 1 is a fixed base (however, movable) provided in the vicinity of the painted surface 14 so that the longitudinal direction of the painted surface 14 is substantially vertical (2). The crank 3 which is pivotally supported on the base end side by the first fulcrum) and which is rotated by the motor 15 through the chain and the gear which are omitted from calling, is located closer to the painted surface 14 than the rotary shaft 7 of the fixed base 1. A base end side is pivotally supported by a rotary shaft 9 (second fulcrum), and an intermediate portion is slidably connected to a tip end side of the crank 2 through a slider 8 so that the crank shaft moves up and down in the drawing in accordance with rotation of the crank 2. The moving links 4 are connected to the side farther from the rotating shaft 7 of the fixed base 1 from the coating surface 14 by a required distance on the fixed base 1 and slidably connected to the base end side via a slider 5, and the spray spray is applied to the front end side. 6 to face the painted surface 14 and the middle to the tip side of the link 3 and the pin 10. Therefore, the slider crank 5 is connected, and while the base end side is slid by the slider 5 in response to the swing of the link 3, that is, the slider crank 5 in which the paint spray 6 swings up and down in the figure, the pin 5 is attached to the slider crank 4. The slider 6 is stopped and engages with the fixed base 1 to slide the base end side of the slider crank 4 on the fixed base 1, and 6 is provided on the front end side of the slider crank 4 by the spray fixing device 11 in the longitudinal position. (Length) Adjustable attachment, a paint spray for spraying paint onto the paint surface 14 by receiving paint under pressure from a paint pump (not shown), 7 is the rotary shaft (first fulcrum) of the crank 2, 8 Is a pin which is pinned to the tip of the crank 2, and which is loosely engaged with the link 3 to swing the link 3 while sliding on the link 3 according to the rotation of the crank 2, and 9 is a coated surface from the rotating shaft 7. Close to 14 A rotary shaft (second fulcrum) that pivotally supports the base end side of the link 3 on the fixed base 1 of the above, 10 is a pin that connects the tip of the link 3 and the middle of the slider crank 4, and 11 is a coating A spray fixing device for fixing the spray 6 to the slider crank 4, a counter weight 12 provided on the base end side of the link 3 as a moment balancer having the rotating shaft 9 as a fulcrum, and 13 a base end of the slider crank 4. The counter weight is provided on the side as a moment balancer with the pin of the slider 5 as a fulcrum.

Next, the operation of the above configuration will be described.

In FIGS. 1 and 2, when the motor 15 is driven, the crank 2 rotates. As a result, the link 3 swings up and down in the figure with the rotary shaft 9 as a fulcrum. As the link 3 swings, the slider crank 4 connected by the pin 10 swings up and down. At this time, since the link 3 and the slider crank 4 are connected (pivotally supported) to each other by the pin 10, the fixed total length of the rotary shaft 9, the pin 10 and the slider 5 (the pins thereof) is fixed to the fixed base 1. The projected length will change accordingly, and since the position of the rotary shaft 9 is immovable, the slider 5 will slide by the change in the length.

Therefore, if the slider 5 is immovable and the pin 10 is slidable, the proximity of the coating spray 6 to the coating surface 14 (when it coincides with the fixed base 1) due to the swing is actually The slider 5 slides and is offset by the amount of movement away from the painted surface 14. In this way, the gap between the tip of the coating spray 6 and the coating surface 14 is kept relatively constant.

When the paint is sprayed from the coating spray 6 under the above-mentioned circumstances, the coating surface 14 is widely coated over the swinging range of the coating spray 6.

In this state, if the fixed base 1 is further self-propelled on a running scaffold, for example, in the direction of the back of the drawing of FIG. 1, the coating surface 14 is also perpendicular to the swinging surface of the coating spray 6. As a result, the vast surface can be coated automatically, efficiently and evenly.

Note that FIG. 3 is illustrated in three steps (a) to (c) in consideration of the above-mentioned operating condition.

In this embodiment, the rotary shafts 7, 9 and the slider 5 are installed on one fixed base 1. However, the fixed base 1 is not limited to the rod shape, and in short, for example, as shown in FIG. It is only necessary that such a positional relationship be maintained for a purpose. Further, it is naturally free to change the spraying angle of the coating spray 6 by changing the device posture.

Further, as a matter of course, when the painted surface 14 moves in the backward direction of FIG. 1 by, for example, a conveyor, the apparatus itself of this embodiment does not need to move.

As described above, according to this embodiment, there is an advantage that, for example, a vast coating surface such as a ship outer plate can be markedly and efficiently and evenly coated.

Since the purpose can be achieved with an extremely simple device, there are advantages that the cost is low and the maintenance is easy.
