[Detailed description of the invention] The present invention relates to a coating device, and in particular, a coating mechanism is hung parallel to the surface to be coated such as a tank side plate, and the coating is applied while moving in both horizontal and vertical directions. The present invention relates to a coating device.

FIGS. 1 and 2 are a side view and a front view, respectively, showing an outline of a conventional coating apparatus of the type described above.

In the figure, a wind girder 2 is provided horizontally along the upper part of the side plate 1 of the tank to be painted, and a traveling mechanism 3 that moves along the same direction is provided.
At the lower end of the rope 5 that is not unwound or wound up from the hoisting device 4 attached to the traveling mechanism 3, a coating mechanism 6 having a spray gun (not shown) or the like is vertically suspended near the side plate 1. It has been done. The traveling mechanism 3 includes a rope guide path 7A that is almost perpendicular to the rope guide path 7A and a rope guide path 7 that is slightly inclined toward the side plate 1 from the vertical direction.
A rope guide member 7 consisting of B is attached, and the rope 5 from the hoisting device 4 is guided and slid by pulleys 8, 8, 8, . . . arranged along this guide member 7. .

When coating the side plate 1 of the tank using such a coating device, the coating mechanism 6 is coated by winding or unwinding the rope 5 from the hoisting device 4 of the traveling mechanism 3 that has been moved to a predetermined position. A spray gun (not shown) is moved up and down vertically along the side plate 1.
Paint is applied by etc. Next, the traveling mechanism 3 is sequentially moved horizontally on the wind girder 2, and painting is performed at each predetermined position while moving the painting mechanism 6 up and down as described above, thereby painting the side plate 1 of the tank.
Painting is applied over the required area.

By the way, there are usually piping 9 on the side plate 1 etc. of the tank.
etc. are often provided to protrude from the board surface, and depending on their height, the painting mechanism 6 may be installed on the side panel 1.
Interference occurs and becomes an obstacle when moving in the horizontal direction. For this reason, in the past, such piping 9
When passing through the installation location, move the coating mechanism 6 to the outside of the side plate 1 using an auxiliary rope (on the right side in Figure 1).
The method used was to move it while pulling it in the direction of. However, this method becomes more difficult the higher the hanging position of the painting mechanism 6 is, and it also requires manual labor to suspend the painting mechanism 6.
Pulling the fuel to the outside of the tank involves great effort and danger. Furthermore, since such work tends to cause the coating mechanism 6 to oscillate, there is a risk that the coating mechanism 6 collides with the piping 9 or the side plate 1 and damages them.

The purpose of the present invention is to solve the problems of the prior art and to provide a coating device that can move the coating mechanism while safely and easily avoiding obstacles on the surface to be coated when painting the side panels of tanks, etc. It is about providing.

That is, the present invention includes a traveling mechanism that moves in a horizontal direction parallel to a surface to be painted, and a guide member that is attached to the traveling mechanism and has a rope guide portion that is inclined at least in the vertical direction. , a coating device including a coating mechanism suspended from a lower end of a rope that is unwound and wound along the guide member, wherein the rope guide portion of the guide member that is inclined with respect to the vertical direction is moved horizontally. It is characterized by being rotatable.

An embodiment of the present invention will be described in detail below with reference to the drawings.

3 and 4 are a side view and a front view, respectively, showing an outline of the coating apparatus according to the present invention.

In the figure, a wind girder 2 installed in the horizontal direction along the upper part of the side plate 1 of the tank to be painted is provided with a traveling mechanism 3 that moves in the horizontal direction. At the lower end of the rope 5 that is not unwound or wound up from the upper device 4, a coating mechanism 6 having a spray gun (not shown) or the like is vertically suspended near the side plate 1. The traveling mechanism 3 is equipped with a rope guide member 7 consisting of an almost vertical rope guide path 7A and a rope guide path 7B slightly inclined toward the side plate 1 from the vertical direction. is guided and slid along this guide member 7.

The above configuration is basically the same as that of the conventional coating device shown in FIGS. 1 and 2, and the third
Corresponding parts in the figures and FIG. 4 are designated by the same reference numerals.

In the present embodiment shown in FIGS. 3 and 4, the guide member 7 is rotatably attached to the traveling mechanism 3 via bearings 10, 10 at the upper and lower portions of the vertical rope guide path 7A. A gear 11 integrally provided on the outer periphery of the guide path 7A is rotated by a motor 12 also installed on the traveling mechanism via a reduction gear 13 and a gear 14.

Further, in this embodiment, the illustrated guide member 7 has a hollow tubular structure, and the rope 5 from the unwinding device 4 is connected to pulleys 15, 15 provided inside the hollow pipe.
15... so that it is not wound up or unwound along the tube axis.

The coating apparatus of this embodiment coats the side plate 1.
The painting work done on the
This is similar to that described for the conventional device shown in FIGS.

The operation of moving the traveling mechanism 3 to the right in FIG. 4 beyond the piping 9 shown in FIGS. 3 and 4 in the painting operation using the apparatus of this embodiment will now be described. The coating mechanism 6 rotates the motor 12 in advance at a position in front of the piping 9 (on the left side in the figure), and transmits the rotational force to the gear 11 on the guide member 7 side via the reducer 13 and gear 14. This causes the vertical rope guideway 7A of the guide member 7 to pivot about its vertical axis, and thus the rope hanging end of the lower, inclined rope guideway 7B to pivot in the horizontal plane. As is clear from FIG. 5, which is a view taken from the - arrow in FIG. 4, when the rope guide path 7A rotates, for example, counterclockwise about its vertical axis O, the rope guide path 7 tilts accordingly
The hanging end of the rope B rotates within a horizontal plane by a predetermined angle in the direction of arrow P in the figure, and from there, the coating mechanism 6 suspended by the rope 5 rotates from the solid line position to the dotted line position to attach the side plate 1. move away from the outside. If the travel mechanism is moved horizontally in the direction of arrow Q in the figure in this state, the coating mechanism 6 will move without being interfered with by any piping 9. During subsequent painting, the motor 12 is rotated in the opposite direction to rotate the painting device again to the painting position corresponding to the solid line position in FIG. 5.

As described above, in this embodiment, the guide member 7 is movable in the horizontal direction with respect to the side plate 1 of the tank to be painted, and the coating mechanism 6 is attached to the lower end of the rope 5 that is unwound or wound up from the guide member. In a device in which the guide member 7 is suspended, the vertical rope guide path 7A is attached so as to be rotatable about a vertical line by a rotation mechanism such as a motor 12, thereby forming an inclined rope guide path. Since the hanging end of the rope 7B is designed to rotate within a horizontal plane, if there is an obstacle such as piping 9 when moving the painting mechanism 6 horizontally along the side plate 1, the motor By rotating the coating mechanism 12, the coating mechanism 6 can be previously rotated in a horizontal plane in a direction away from the side plate 1, thereby making it possible to perform horizontal movement without any interference with the piping.

In this case, the rotation operation is carried out completely automatically by the motor, without any effort or danger to the operator. Further, since the rotational force from the motor 12 is applied via the reducer 13, the rotation of the coating mechanism 6 is performed smoothly and reliably, and the sudden vibration during rotation can cause damage to the coating mechanism 6 itself, the side plate or the like. There is no risk of damaging the piping 9. Further, this rotational operation can be easily performed regardless of the vertical position of the coating mechanism 6.

Furthermore, in this embodiment, the guide member 7
has a hollow tubular structure and the rope 5 is slid along the tube axis by pulleys 15, 15, 15... installed inside it, so that the rope is unreeled from the pulley on the rope unwinding side. The positional relationship between the rope guide path 7A and the rotation center of the rope guide path 7A is always kept constant, and the rope 5 will not come off the pulley.

Also, if necessary, the posture of the painting mechanism 6 may be adjusted with an auxiliary rope or the like when the piping 9 passes through it, but in this case, the overlapping of the painting mechanism 6 itself is entirely provided by the rope 5, so it is extremely difficult to Applying a small amount of force is sufficient.

In this embodiment, the guide member 7 is driven by a rotating mechanism such as a motor 12, but any drive source such as a hydraulic pressure or a pneumatic cylinder may be used for the rotating mechanism. Further, the apparatus of the present invention can be applied not only to the side plate of a tank but also to any case where painting is performed while moving the painting mechanism relative to the surface to be painted.

As described above, according to the present invention, the painting mechanism can be moved safely and reliably during painting work without any interference with obstacles present on the surface to be painted.
