Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an apparatus used for coating objects, such as helmets, which are difficult to coat uniformly with ordinary coating machines.

The purpose of this invention is to be able to apply uniform coating to the entire surface of the object to be coated, no matter what form it is in. To achieve this, the coating gun is moved in a rectangular wave pattern to apply the coating. The purpose of the present invention is to provide a coating device that is capable of

That is, in the present invention, a table 2 for setting a workpiece W to be coated is rotatably installed inside an apparatus main body 1, and vertical guide columns 3 and 4 are erected on the left and right sides of the table 2, and each guide column 3 and 4 has a side surface. Guides 7 and 8 for moving the painting guns 5 and 6 in the front and rear directions are attached so as to be movable up and down, and these are attached to the winding body 12 of the vertical operation mechanism 11 by hanging wires 9 and 10. A guide 15 is provided with guide rods 13, 13 for moving the upper surface coating gun 14 in the left and right direction.
Installed so that it can move left and right, each painting gun 5, 6, 14
This is a coating device whose operation is controlled by position detection elements 16 of the table 2.

The coating device of the illustrated embodiment has a pair of guide columns 3, 3, 4, 4 at the front and rear of the left and right sides of the main body, and guide rods 13, 13 in the front and rear direction are attached to the upper ends of the guide columns 3, 4, respectively. , 4, and 4 are vertically movable, and are lifted and lowered with the side painting guns 5, 6 and their guides 7, 8 mounted thereon. rail 19,
It is attached so that it can freely move back and forth along the rails 19 and 20, and is pulled by a connecting member 22 to move back and forth by a chain 21 that is arranged in parallel to each rail 19, 20. 17
a, 18a are engagement pieces with the guide columns 3, 4, 23,
24 is a sprocket of the chain 21; 25 is a roller running on the slope of the guide rails 19 and 20; 26
is a motor, 27 is a speed reducer, 28 is a drive shaft extending from the left side of the main body on the driving side to the right side and synchronizes the painting gun 5 on the right side via a chain 21' on the driven side, 29 is an interlocking wheel, and 30 is a chain. show. hanging wire 9,
10 are respectively wound around an upper shaft-like winding body 12, and the lower ends thereof are connected to the lifting beams 17 and 18, and are wound and unwound by a winding motor 31 via a speed reducer 32. 33 and 34 indicate wire direction changing pulleys.

The upper surface painting gun 14 is mounted so as to be movable left and right via a guide 15 on a movable beam 37 which pivotally supports rotors 35 and 36 on both sides of the guide rod 13, which move back and forth on the guide rod 13. It has rolls (not shown) running on guide rails 38 and 39 along the moving beam 37 in the same way as the direction guides 7 and 8, and is pulled by a chain 43 that moves left and right by a motor 41 via a reducer 42. and move. 44,4
5 indicates the sprocket of the chain 43. 4
6 and 47 are racks provided along the left and right guide rods 13, and 48 and 49 are engaged with the racks, and the top surface painting gun 1
4 is a pinion that moves back and forth, 50 is its motor 5
Reference numeral 1 indicates a reduction gear, and 52 indicates a connecting shaft for left and right pinions.

The table 2 on which the object W to be coated is set is driven by a drive shaft 53.
are connected by a chain 54 and sprockets 55 and 56, and on one side of the sprocket 55 there is an element 1 such as a limit switch for detecting the position of the table 2.
6a, 16b, 16c, 16d, . . . A disk 58 is provided with members 57a attached thereto. The table 2 and the like are controlled to rotate or stop by a drive source (not shown), and painting is performed during this time. That is, the rotational position of the table 2 is detected by the position of the disk 58, and which gun 5, 6, 1 is used to paint the object W.
4, how many times and how to spray the paint is determined by external operation. The operation may be manual or programmed, and the painting work can be smoothly performed by freely operating the side painting guns 5, 6 and the top painting gun 14, respectively. Also table 2
The object W to be coated can also be coated while rotating.

In particular, according to the present invention, the side painting guns 5 and 6 are capable of performing composite moving painting in each direction, front and back and up and down, and the top surface painting gun is capable of performing similar painting operations in each of the front and rear and left and right directions. , the entire surface of the object to be coated can be coated evenly, and quick and accurate operation can be expected.
