Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides long objects, especially long objects that can be twisted spirally! ll
The present invention relates to a nine-coat reconnaissance device particularly suitable for broadcasting l1.

Conventionally, long objects have been coated using various methods such as using dies, using rolls, using brushes, using belts, and inserting the coating into a nozzle that has the same external shape as the object to be coated. It has been nine years since the painting was done. However, with these methods, it is difficult to uniformly apply a relatively thick coating due to rounding, which increases the shear rate during coating, and it is also difficult to obtain a uniform coating thickness when the object to be coated has unevenness. There was a problem with the shoe.

There is also known a method of dip-coating a long object using a tank in which a coating solution is poured and fixed. However, with this method, it is extremely difficult to coat objects that are extremely long, have a large weight, and are difficult to transport.

The painting of rounded and heavy long objects is done by hand with a brush, for example, by a person sitting on a chair suspended from low fK, or by a person riding in a Pundra. Ta.

However, these ms methods have drawbacks such as safety problems in working at heights11, unfavorable environmental hygiene due to scattering of the coating liquid, and low efficiency in manual rounding work.

+ Nite proposed a coating device that was fixedly installed on the upper and lower 7J1111 and specifically passed through the m-length of the hanger Ronig for a nine-length bridge, for example.

Please refer to Figures 1 and 3 of this painting equipment
Explain briefly.

In Figure @1 and Figure 4g2, a stern hanger rope l, which is an example of a fallen object, is shown in a sectional view and a 1111 side view, respectively. As shown in the figure, the hanger rope 1 is formed by twisting a plurality of steel wires into a spiral shape. For this reason, the outside J of the hanger rope l
IIIK is formed with spiral irregularities.

The equipment shown in Figure 3 has two sets of supply tanks - m supply tank 3.
, a coating liquid recovery means 4, and a turning means S, each of which is integrally formed. The weight of the replenishment tank 3, the paint tank 3, the coating liquid collection means 4 and the VII single-time means S is supported by the base 6, and the base 6 is connected to a pivoting lobe 9 forming a driving means. is connected to a hoist (not shown). Rope 7f driven by hoist
: By unwinding, the base 6 descends, thereby
The supply tank weight, paint tank 3, coating liquid recovery means 4 and rotation means S also descend. As described above, the hanger rope 1 is formed in a spiral shape, and the sealing member 8 of the tank 3 and the brush of the coating liquid recovery means 4 surround and contact the hanger rope LT. (possibly), or turning means 2
Supply tank 3, paint tank 3
, the coating liquid collecting means reef and the rotating means S move down while rotating together to coat the hanger row fl.

Although the O coating apparatus shown in FIG. 3 has excellent effects such as being able to efficiently coat long objects, it also has the following O points for improvement.

In the Wi-Table device shown in Figure aS, the paint tank weight rotates, so the supply tank 2 and paint tank 3 must be connected.

If the object to be coated is long and the corresponding paint must be kept in the replenishment tank 8, the part that rotates as one unit, i.e. the replenishment tank weight, one core as a whole, such as obstetrics WI3, etc. The higher the resistance, the greater the inertia. As a result, stable rotational movement becomes uniform, making it difficult to properly rotate the sealing member island according to the spiral shape of ***.

In the case of the coating device shown in Fig. 3, multiple TNG!
Jt - When painting at the same time, there are at least as many supply tanks 1 as there are objects to be coated! is required. For this reason, the painting f! # has a relatively complicated structure.

Unfortunately, in the painting apparatus shown in FIG. 3, the parts that rotate together, such as the supply tank 8 and the paint tank 3J$, are simply placed on the base 6 and are not connected thereto. During this rounding and painting work, there is a possibility that the rotating part may be left in the middle of the object to be coated.

(9) If the resistance between the sealing member 8, etc. and the object to be coated l is large, the rotating part will not descend quickly, and therefore, rapid coating will not be possible.

The present invention has been made in consideration of the above-mentioned circumstances.
According to the present invention, in a coating apparatus comprising a paint tank having an opening in the bottom 11 through which the object to be coated passes and a ninth drive unit for moving the paint tank with respect to the object to be coated, mosquitoes in the paint tank are provided. A coating apparatus is provided, comprising a sealing member rotatably disposed in the opening and having a round hole that matches the outer shape of the object to be coated.

It is an object of the present invention to provide a nine-meter coating device suitable for coating long objects, 411 spirally twisted objects.

Another object of the present invention is to provide a coating device which is particularly effective for coating long articles twisted in a spiral shape, which are heavy or whose movement is solid due to the installation. .

Another object of the present invention is to provide a coating that can be twisted spirally and can be applied continuously, quickly and uniformly.
- To provide.

The foregoing and other objects will become apparent from the following description of a preferred embodiment of the I/I/1 loading bulk of the present invention, with reference to the accompanying drawings.

With reference to FIGS. 4 and 5, one embodiment of the smearing device according to the present invention will be described.

In this specific example, the device has two parts: a mounting part 1g and a support part 1g.
4, a compensation section 16, and a support section llu.

tmm iron car 18#1 is provided on each of the three hanger ropes l to be hung. The number of coats and parts can be changed arbitrarily depending on the number of coated items such as hanger loaf '1. These painted parts! have the same structure, so
I will explain one of them. The coating section 18 has a paint tank 3, and an opening is formed in the bottom 11 of the paint tank 3. A hanger quart l extends through this opening. A hole is formed under the bottom of the paint tank so as to surround the opening tMRn. This hole/! OK, so the seal member S is rotatably held. Seal member S
A hole having a shape approximately equal to the cross section of the hanger rope l is provided inside the hanger rope l. The external conductor of the sealing member S is formed in a circular shape, so that the sealing member S as a whole has a disk shape with a hole in the center. Holder 5oFi
, a radius approximately equal to the radius and height of the sealing member S, and i
It consists of a side and a bottom wall forming an I4-sized cylinder. Accordingly, the sealing member 8 is supported so as to be able to turn around. In this specific example, the holder lO is composed of a side for housing the seal member holder and a holder as described above, but the holder sO may have any configuration that rotatably supports the seal member holder.

holder! ! There is also an IiK roller that extends downward, and this roller! As shown in the figure, 8 maintains the proper arrangement direction t- of the hanger rope lKiiML, llilfj part lf, and the painted part l! Make sure that the hanger rope l moves smoothly in the direction of the hook.

For this reason, the axis of rotation of the row 282 is in the plane of water'sP, and the number of rows 282 may be three as shown in the figure, or three or more as shown in the figure.

Although not shown, the painted part l! ! It is constructed so that it can be divided into two parts each, such as the 0.1 billion tank 1, the sealing member 8, etc., and thereby the already installed hanger row
- It is preferable that the hanger rope l'f can be inserted into the central hole of the paint tank 3, the sealing member 8, etc. without being removed. If you keep it, seal material $
It is made up of eight parts, and the remaining parts can be connected by removable connecting members. or,
The sealing member 8 can be cut with two cutting planes extending from the hole to the external conductor, and the sealing member can be deformed so that it can be placed into the central hole of the sealing member through these cutting planes. The material of the sealing member may be an elastic material or an inelastic material.

The support part 14 is a support stand! ! 4 and 4 support rods 3@, 28 and 8 support wires 30% s! ! It is equipped with Support stand! Support wires 3, 31 are connected to the upper and lower parts of 4, 9, support rod 2g, and support wires 3, 31! are connected. Support stand! 4 top 11
Kmik tank wealth is installed), the upper part of the supply tank 2 and the support stand! A driving rope i is connected to the lower part of 4. As mentioned above, one end of support wire no.
The tip of the KA is connected to the top of the paint tank 3 or the roller s! 2t - each connected to the lower part of the supporting wax. The number of support wires go, ms is 8 as explained above.
It is preferable to use a book, but if it is not necessary to increase the number of wires to obtain more stability, you can omit the lower support wire S3 and use only the upper support wire sO! <, I! If the connecting part of the support wire and the paint tank is relatively close to the hanger line, or if the support wire and the hanger line direction are equal, the paint W&w1! You can have one for each. A support rod that can be used even when the spacing of the three hanger ropes is different! @, 1 g or 30% of the wire support wire The length t of s8 is preferably configured to be adjustable.

The supply unit 16 includes a supply tank 2, a supply pipe 3, and t. When supplying paint, the supply tank snow does not communicate with the atmosphere except through the passageway that communicates with the supply pipe 34.
The supply tank 3 holds a sufficient amount of paint and gradually supplies Klk to the paint tank 8 via the supply pipe s4. Supply pipe 34
is made of a flexible material and has a hook 3, the outlet of which is installed in the paint tank 3 so that its height can be adjusted. Therefore, the supply tank 8 and the painting part l! Even if there is relative vibration during the 1lki1 operation, it will not be affected. Since the outlet of the supply pipe 34 is installed so that the height can be adjusted, the adjustment of the paint o*tvs in the paint tank 3 is difficult.

Furthermore, as mentioned above, the supply tank weight is communicated with the atmosphere only through the supply pipe s4, so the amount of paint in the paint tank 3 is maintained at a constant level.

The drive unit 18 includes a drive rogue and a winding wheel (not shown). As mentioned above, the trunk rope is in the supply tank 2.
The top and support base! It is connected to the lower part of 4. Compared to the resistance force between the sealing member a and the hanger loaf l,
If the painted part lit has a sufficiently large 1ili, then the painted part l! When the machine suspended by the support rod 8 and the support wire 1 is returned to its original position and the driving Roguema is lowered, the roller is lowered.

On the other hand, if the resistance force between the sealing member S and the hanger rope l is relatively large, it is OK to increase the weight of the support wire 4 to apply a downward force due to the snow on the support wire 3, or to increase the weight of the lower driving rope. Support rod wing 8 and support wire S
! As a result, a downward force is applied to the coating portion 12, thereby causing it to descend.

Next, the operation of the coating apparatus according to this embodiment will be explained.

First, the sealing member is placed so as to surround the hanger rope through the cut surface. Next, the paint tank S is divided into eight parts, for example, along the dividing plane through its central axis, so that the sealing member base is supported by the holder sOK and the paint tank 3 surrounds the hanger rope 1, T-plate, and D. Place it in Of course, the painting department! A support stand! It is supported by a support 1614 consisting of a reef, a support rod, 8S and a support wire of 30% S8,
The driving rope bearer is connected to the supply tank 3 and the support stand 24. Next, the cock S@ is opened and the paint stored in the supply tank 3 is introduced into the paint tank 3 through the supply pipe 34.

Next, the hoist is operated to sequentially unwind the drive roller and, if necessary, apply a downward force to the paint tank 3 to lower the paint tank 3t.

The inner surface of the hole in the seal member 8 has a good shape that matches the outer shape of the hanger rope 1, and since the seal member a is rotatably held in the holder 20, when the paint part 18 is lowered, 1. The sealing member 8 moves along the helical shape of the hanger loaf l, so that the sealing member 8 rotates about the center @l/IA of the hanger rope l. As described above, since the inner surface of the sealing member S has a shape t that matches the outer shape of the hanger loaf 1, the amount of paint leaking between the sealing member 8 and the hanger loaf fl is small.

In addition, adjusting the obstetric viscosity so that the rate of paint leakage is more uniform than the rate of descent of the paint tank 3 can also help reduce paint leakage.

Further, in the specific example shown in FIG. tJI/44 and FIG. 5, the sealing member 8 is surrounded by the cylindrical side and bottom wall of the holder 2G. Therefore, the paint 1 may leak to some extent through the interaction between the outer layer of the seal member 8 and the cylindrical wax and wax. It functions as a lubricant for these thresholds, and the circle fW of the sealing member 8 within the holder 2o! It sings to help the rotation. Also, if you have nine, you should finish it! The bottom wall of the hanger 11 is configured so that it is close to the hanger 0-g, and the paint leaking between the sealing member and the hole 110 is prevented.
KJI can be made to attach IK to the unpainted hanger loaf below Holme Snow O. by this,
The possibility of leakage between the seal member 8 and the hole closure 20 can be eliminated.

In the coating apparatus according to the present invention, only the seal member a rotates, and the paint tank 3 and the like do not rotate. With this rounding, a single supply tank weight can be used for a plurality of paint tanks 3. I
! A downward force can be easily applied to the paint tank 3, etc., thereby making it possible to quickly lower the paint device and quickly paint. Further, since the seal member S has a small inertia, it rotates so as to appropriately follow the spiral shape of the object to be coated, and leakage between the seal member $ and the object to be coated can be minimized. In addition, since the paint inspection vehicle is connected to the replenishment tank, etc. via the support wire sO1aX, if the replenishment tank, hanger loaf, etc. vibrate due to wind, etc., those vibrations will be absorbed by the support wire II.

11, its effect on painting work is extremely small.
