Description

[Detailed description of the invention] This invention uses anaerobic curing or other sealants or adhesives on the outer periphery of threaded parts of items such as screws, bolts, water pipe joints, gas nozzles, or L-shaped and T-shaped nipple joints. The present invention relates to a coating device for coating a chemical or the like.

Conventionally, the above-mentioned items were laid horizontally and fed onto a coating roll to be coated with a coating liquid, but this had the disadvantage that after coating, the coating liquid flowed downward due to gravity, causing uneven coating in the circumferential direction. . In order to prevent this uneven coating, a method of feeding the article vertically has been considered.In the past, the coating liquid was pumped up and applied using a plate, but this method was inefficient as it took time to move the plate up and down, and the coating liquid A large amount of adhering to the lower part and lower end surface of the article required wiping it off. Additionally, those that supply the coating liquid through a nozzle have the disadvantage that the nozzle is easily clogged.

The present invention eliminates such drawbacks by supplying the article upright and applying it with a coating roll while keeping it horizontal during coating.After coating, the article is quickly stood upright while rotating on its own axis to prevent the coating liquid from dripping. This was prevented.

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

This apparatus is roughly divided into an article supporting apparatus A, an article holding apparatus B, and a coating liquid coating apparatus C.

A support plate 24 provided vertically in front of the rail 19 is provided with a gear 25 for accelerating the rotation of the holder 12 that frictionally engages with the knurling 16 of the holder 12 that is horizontally tilted forward. It is connected to a motor (not shown) via 26.

A support stand 30 of the article holding device B is fixed to the front end of the base 1, and a pair of bars 31, 31 extending in the front and back direction are fixed on this support stand 30.
1 and 31, a slide 32 is fitted in order to move back and forth, and this slide 32 is connected to an air cylinder 33 for back and forth movement. This slide 32 supports for rotation a holding rod 35 having a conical body 34 at the tip facing the front end surface of the article 11 of the holding body 12 that has fallen forward, and this holding rod 35 is equipped with a motor for rotation. Connect to 36.

As shown in the first and third figures, the support plate 40 of the coating liquid coating device C is positioned between the support plate 24 and the support plate 30 on the base 1 so that it can be adjusted back and forth using a long hole 41 and a bolt 42. A tank 44 containing a coating liquid 43 is provided on the support plate 40 so as to be rotated by a motor 45. Support column 4 planted on support plate 40

In FIG. 1, 74 is a control box.

Next, the operation of this device will be explained.

An article 11 having a screw 11a to which a coating liquid 43 is applied, such as a water pipe joint, as shown in the second figure.
is the pin 18 on the upper surface of the holder 12 as shown in the second figure.
directly or indirectly through the jig 17.

The support plate 3 and the turret plate 5 rotate clockwise intermittently by a constant angle θ in FIG. Regulate accurately.

Thus, when the holder 12 comes to the position of the magnet 21, the holder 12 is rotated outward about the shaft 9 by the guide member consisting of the magnet 21 and the rail 19.

When the holding body 12 escapes from the groove 4 of the turret plate 5, the body 14 of the holding body 12 moves to the rail 19.
It rotates outward while rolling on the front part 22 of the machine, and becomes horizontal at its lowest position. At this time, the gear 25 engages with the knurling 16 of the holder 12, and the body 14 rotates at a high speed.

On the other hand, the slide 32 is moved backward by the air cylinder 33, and the conical body 34 of the holding rod 35 fits on the front surface of the article 11, and the article 11 is moved between the holding body 12 and the holding rod 3.
5, and rotates the article 11 at high speed by the rotational force of the holder 12 and the holding rod 35.

Furthermore, the lifting platform 51 is raised by the cylinder 49,
The shaft 55 of the bearing plate 52 supported by it also rises,
The application disk 56 comes into contact with the lower surface of the article 11 and applies the application liquid 43 to the thread 11a.

Further, the piston 72 of the air cylinder 71 is lowered, and the spatula 73 at the lower end is inserted into the screw 11a of the article 11.
The coating liquid is applied uniformly to the circumferential surface.

After this application is completed, the air cylinders 33, 49, 71
operate in the opposite direction, holding rod 35, application disk 56,
The spatula 73 returns to its original position, and immediately thereafter the support plate 3 and the turret plate 5 rotate, and the holder 12 holding the article 11 coated with the coating liquid rapidly moves onto the front part 23 of the rail 19 while rotating. rise diagonally upward and stand upright. Therefore, the coating liquid applied to the article 11 does not droop downward due to centrifugal force.
It adheres to the article 11 and dries.

In the above device, when the threaded portion 11e is inclined as shown in the article 11b shown in FIG.
Tilt it to match the taper of.

As described above, in the present invention, since the articles are fed in an upright position, it is easy to feed the articles, and the articles and their holders are guided horizontally at the front of the support disk, and in this state, the coating liquid is applied to the articles by the coating disk. After coating, the article is rotated and quickly stood upright to prevent the coating solution from dripping, which prevents uneven coating and allows the coating solution to be applied evenly to the circumference of the article. It is possible.
