Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface treatment apparatus for bonding mechanical elements, small metal fittings, etc., and in particular, the present invention relates to a surface treatment apparatus for bonding mechanical elements, small metal fittings, etc. The present invention relates to an apparatus for performing surface treatments such as liquid removal, coating, liquid removal, and drying.

Shaking, vibration, such as vehicles, construction machinery, and other automatic control equipment,
For equipment and durable equipment that are susceptible to shocks from external forces, it is necessary to perform surface treatment in advance before installation to prevent premature loosening and corrosion of the members and fastening fittings used to assemble the equipment. In order to meet these demands, various hydrogen parts have been proposed to be machined from corrosion-resistant materials or have special structures to prevent loosening. However, such members are not preferred in terms of production costs and complicated structures, and in terms of speed of work. On the other hand, the conventional parts are coated with anti-corrosion paint.
A fixing means is employed in which adhesive is applied to prevent loosening.

To apply the above-mentioned paints and adhesives, first wash the parts with alkaline liquid, acidic liquid, hot water, etc. to remove oil and seat valves that adhered during manufacturing, drain the liquid, and then
After applying an adhesive or the like to the part, it is dried.

Conventionally, in order to sequentially perform the above-mentioned processing steps on a large number of the same small parts, a basket containing the parts was suspended from a chain trolley installed on the ceiling of the factory, and the basket was placed in a liquid tank without running. The adhesive is immersed, washed with a separate stirring means, and then left to drain naturally.Then, the adhesive is transferred either manually by a worker or with a trolley+ to an adhesive liquid tank, and while immersed, it is washed with an attached manual stirring means. I painted it thoroughly and moved it out.

However, in order to perform various surface treatments using such a transfer mechanism, there are many cases where manual transportation and operations using attached hand tools are required, and in addition, the processing equipment is bulky and requires a large site area.

While moving to the third position, it rotates in the forward direction to stir the objects to be processed as described later, and at the third position, it rotates in the opposite direction to discharge and drop all the objects to be processed, and after discharging, it returns while rotating in the opposite direction. When it reaches the first position, it stops with the opening 44 facing upward as shown in the figure.

As shown in FIG. 3, the packet 30 has end plates 46 completely fixed to both side edges of a body plate 45 whose cross section is curved in a spiral shape. The outer end of the body plate 45 forms the opening 44, and both end plates 46 may include the socket shafts 31. As shown in FIG. 4, the body plate 45 has a first body plate portion 45a extending in a curved manner from the opening 44, and is formed into a semicircle with a radius R centered on the zero point. It is assumed that a line segment 'tAB' connects these two edges. The wire plate portion 45b is extended. Furthermore, the second body plate portion 45
b A third body plate portion 450 is formed as an extension, with the tip edge 0 as the center and OC as the radius R'.

The leading edge of the third body plate portion 450 is 4
It extends to a radial line segment 48 with an included angle of 5°. When the thus constructed bucket 30 is rotated in the direction of arrow 49 shown in FIG. 4 (referred to as forward rotation), the articles to be stored and processed are agitated without falling out of the bucket one by one. , when rotated in the direction of arrow 50 (referred to as reverse rotation), the stored articles to be processed are discharged through the packet opening 44.

The base of a chute 52 is pivotally attached to the lower peripheral edge of the opening 4 of the housing 1, and a support rod 53 is provided horizontally from one side of the chute 52, with an air space between the support rod 53 and the lower part of the front wall 2. A compressor 54 is provided, and when the article to be processed is introduced into the packet 30, a compressor disposed at an appropriate location is activated by a signal from an electric control circuit, and the chute 52 is moved to a second position.
The article is pushed up to the caustic line position, and the article to be treated is reliably introduced into the first position of the bucket 30 through the opening 44.

When the injection is completed, the arm 2 descends to the chain line position.
8 so that there is no problem even if the packet 30 moves.

To explain another embodiment for pushing the chute 52 upward, the shaft to which the chute is pivoted is extended to the outside of the side wall of the housing 1, and the engaging rod protrudes radially from the tip thereof, while the upper end of the cover plate is A configuration may also be adopted in which the chute 52 is provided at a more lateral side so that when the cover plate is lowered, the tip of the chute presses the engagement rod to push up the chute 52 to a predetermined angle of inclination.

On the front of the housing 1 is a hotspot 5 that normally stores all the objects to be processed.
5 is provided, and a chute 56 is provided at the bottom of the hole)"-55 to automatically slide and extend to connect with the chute 52,
The trap is constructed so that the amount of articles to be processed to be processed in one work process is supplied by opening the Dunnog-57.

The present invention constructed as described above will be explained in detail.

- When the kerato 30 is placed in the first position within the housing 1, the lid plate 1o is lowered by the lifting mechanism to open the opening 4 and the chute 52 is raised to the upper position. Then, articles to be processed for one operation are put into the bucket 30. The articles to be processed flowing down the chute 52 directly fall into the gap 44, but some of them once collide with the body plate portion 45b and flow down/
Each ticket is stored between tickets. On the other hand, the chute 56 contracts, the chute 52 retreats downward, and the lid plate 1o rises to close the opening 4.

When the lid plate 10 is closed, the ticket 0 rotates forward in order to stir the stored articles. Since half of the kerato 30 is immersed in the paint liquid in the liquid tank 23, the paint is applied to the entire surface of each agitated article to be treated. When the coating process has elapsed for a set time, the electric control circuit rotates the shimotor 34 to move the arm 28 upward to the second position. Second
At this position, the kerato 30 is lifted from the position where it is immersed in the paint liquid, and the ticket is rotated in the forward direction to remove excess paint liquid and drain the liquid.

When the liquid draining step is completed, the arm 28 is swung to move the packet 30 out of the housing through the opening D5 in the rear wall of the housing. At this time, if the paint liquid is quick-drying, it will dry during draining, so the delivery vehicle 6° is placed directly behind the first device without requiring a second device. However, if the button is not sufficiently dry, a second device is installed behind the first device.

When the set time for the liquid draining step ends, the lifting mechanism of the second device lowers the lid plate 1o of the second device and the lid plate 11 of the first device, opening the openings 4 and 5, and opening the second device. The chute 52 of the device is raised. And one ζket 3 which is rotating forward
0 is moved by the arm 28 and stopped at the third position.

The /9 bucket 30 stopped at the third position immediately rotates in the reverse direction according to a signal from the control circuit to discharge the stored article. The empty bucket 30 is rotated in the opposite direction while being moved by the arm 28, stopped at the first position, and rotated with the opening 44ft facing upward in order to receive the article to be processed for the next operation. It has also stopped working.

On the other hand, the article to be processed discharged by the single bucket of the first device is guided by the chute 52 of the second device and the surface of the body plate portion 45b of the single bucket 30, and passes through the opening 44 to the second ticket. It is stored in 0. During this time, the front and rear cover plates 10.11 of the second device are closed and the hot air fan 24 is activated. Then, when the article to be treated is stored, it rotates in the normal direction to accelerate drying. When the desired set drying time is over, the operation of the hot air fan 24 is stopped, the opening 5 is opened, and the packet is directly moved from the first position to the third position outside the apparatus. Then, the rotation is reversed and the article to be treated whose surface treatment has been completed is loaded into the delivery vehicle 60. The bucket 30 is then moved to a first position and is ready to receive the next coated article.

The apparatus of the present invention, which has the above-mentioned functions, performs various surface treatment operations on objects to be treated by rotating the keratola, which is mounted between the ends of both arms, on its own axis, and swinging the arms to revolve/revolve the tickets. The device is made compact by organically combining the transfer operation and transfer operation.

The cross section of the ticket is formed into a spiral shape, and when it is rotated in the forward direction (the opening direction), the stored and processed items are agitated without being separated, so they can be cleaned by cleaning liquid, resist adhesion of adhesive liquid and paint liquid, and can be heated easily. Drying using an air blower can be done quickly and thoroughly. Then, when the kerato is rotated in the reverse direction, the stored articles can be completely ejected.

Furthermore, since the arm that supports Keratra in a rotatable manner is attached to the casing so that it can be stopped at a desired position and can swing in and out of the casing, it is possible to carry out various surface treatment operations and transport and unloading operations of the objects to be processed. I can reprimand you.

Since it is equipped with an arm with a socket each having the above-mentioned effects, cleaning of objects to be treated, application of paint, and adhesion resistance treatment of adhesives can be done simply by changing the type of liquid in the liquid tank disposed. For drying, all you need to do is install the hot air heaters, and when performing several types of surface treatments in succession, you can simply assemble and connect the devices mentioned above, which can be done quickly and reliably without the need for manual labor. It is possible to process.
