Description

Camera Device of Snout < RTI ID = 0.0 >

The present invention relates to a camera device of Snooth which is installed at the end of a Snooth used in a hot dip galvanizing process and photographs a plating process of a strip, and more particularly, to a camera device of a conventional camera device, I would like to propose Naut's camera device.

As shown in Fig. 1, Snooth (A) is a device which is put on the outer surface of a strip C that is between a drawing roller of a heating furnace and a drawing roller B1 of a plating bath B in a hot dip galvanizing process, A camera D3 and an illumination light D5 are installed at the end of the snout A to see how the strip C is drawn into the bath surface of the plating bath B.

The principle of the conventional camera apparatus D installed in the snout A as shown in Fig. 2 is that the duct D1 inclined at the peripheral wall of the snout A is provided and the end of the duct D1 And a camera 30 is mounted on the glass plate D2. The illumination light D4 is also mounted on the same principle as the camera D3.

However, in the conventional mounting method as described above, the deposition gas generated inside the Snout A is deposited on the surface of the glass plate D2 for a long period of time, and the image quality gradually becomes blurred.

Conventionally, the camera 30 is dismantled and the glass plate D2 is separated and cleaned frequently. However, this operation is considerably cumbersome and the cleaning operation is difficult due to the heat and the high temperature.

An improvement is made in that a plurality of nitrogen gas supply nozzles D5 are provided on the entire surface of the glass plate D2 to form an air curtain on the surface of the glass plate D2.

However, the addition of the nitrogen gas supply nozzle D5 and the supply of the gas in the form of the air curtain will increase the area of the glass plate D2 and considerably increase the consumption of the nitrogen gas. As a result, not only the economical efficiency is reduced but also a large amount of nitrogen is injected into the slurry (A) due to the increase of the pressure inside the slump (A) Resulting in a plating problem.

Japanese Patent Application Laid-Open No. 10-2013-0138303, Japanese Patent Application Laid-Open No. 10-1053197, Laid-Open Utility Model No. 20-2000-000218.

The present invention solves the problems such as blurred image quality, frequent cleaning and consumption of nitrogen gas due to the camera device mentioned in the background art, and thus, problems such as pressure rise and temperature drop, property change, plating defect, In particular, it is possible to improve the image quality of a conventional camera mounting structure installed in Snout, to improve image quality, to eliminate cleaning, and to significantly reduce the consumption of nitrogen gas, thereby naturally changing the conditions inside Snout Which can reduce the size of the camera.

As a means for solving the above-mentioned problem, the principle of the Snout camera device proposed in the present invention is that a camera is installed at the inner end of a tube having a narrow outlet, and the tip of the tube is mounted through the peripheral wall of the end of the Snout , And nitrogen gas is supplied to the inlet of the tubular body so that the nitrogen gas is discharged in such a manner as to be compressed at the outlet of the tubular body.

According to the above-described means, the camera device of the present invention does not need a configuration for implementing the duct D1, the glass plate D2, and the air curtain applied to the conventional camera device, and the consumption of nitrogen gas can be remarkably reduced. Accordingly, the camera device according to the present invention is cleaner than conventional camera devices because foreign substances are not deposited and the image quality is clean, and there is no place where foreign substances can be buried. Therefore, cleaning is unnecessary and nitrogen gas is injected into a narrow space to be compressed It is economical because it can reduce the consumption of nitrogen gas. It is unnecessary to adjust the pressure and temperature inside Snooth which is operated to prevent the pressure and temperature drop inside Snooth due to excessive supply of nitrogen gas, At the same time, it is possible to dispel the worry about defects due to the change of the strip. Further, the camera device according to the present invention has a simpler structure than that of the conventional camera device and is easy to apply to Snout, thereby remarkably improving the cost savings due to manufacture and installation.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. It is to be noted, however, that the appended drawings are exaggerated and may be exaggerated, omitted, or schematically illustrated for convenience of explanation. The terms and names used in the following description are not limited to the dictionary meaning, but can be defined implicitly by the shape, function, and role of the structure. In the following description of the present invention with reference to the drawings, the description of the position will be made with reference to the drawings unless otherwise specified. And specific descriptions of well-known and commonly-used technologies may be omitted to avoid obscuring the subject matter of the present invention.

As shown in FIG. 1, the present invention is directed to a Snooth (A) applied to a hot dip galvanizing process, and as shown in FIG. 2, is conventionally provided at the end of Snooth (A) A glass plate D2, and a plurality of nitrogen gas supply nozzles D5, and a camera device in which an external photographing method and an air curtain method are combined.

3 to 4 are views showing a camera device of Snooth according to the present invention. As shown in FIG. 3, the present invention includes a camera mounting module E in the form of a syringe, .

Hereinafter, a camera device of Snooth according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a sectional view of the camera mounting module E. The camera mounting module E includes a main housing 10, a mounting plate 20, a camera 30, a nitrogen gas inlet tube 40). The accompanying drawings show the structure of the camera mounting module E as simple as possible for easy understanding.

Hereinafter, a detailed description of the components and an organic coupling relationship between the components will be described.

The main housing 10 has an inlet 11 in the form of a tubular body with an inclined portion 12 tapered at an inner end of the tubular body and an outlet 13 at the end of the inclined portion 12 The outlet 13 is formed at the center of the portion bent inward from the end of the inclined portion 12 and the outlet 13 is formed to a size large enough to secure the field of view of the camera 30 , And the inlet (11) has a structure separable from the tube portion.

The mounting plate 20 is inserted into the main housing 10 and is capable of blocking the front and rear of the inside of the main body 10 in the form of a partition, A plurality of communication holes 21 are formed along the outer circumference of the surface on which the first and second connecting members 30 and 30 are mounted.

The mounting disc 20 is inserted into the main housing 10 with the camera 30 mounted thereon and fixed to the end of the tube 13 on the side of the outlet 13. The mounting disc 20 is fixed to the inside of the tube And may be fastened by bolts and fastening means while being not shown, or they may be fastened by applying a step

The camera 30 fixed to the end of the tube of the main housing 10 by the mounting plate 20 causes the front end lens portion 31 of the camera 30 to approach the inclined portion 12, The outlet 13 of the main housing 10 is bent inwardly from the end of the inclined portion 12 so that the camera 30 is bent in the same manner as the inclined portion 12 So that the diameter of the outlet 13 is sufficiently large enough to secure the field of view of the mounted camera 30.

The camera 30 may be a small camera including only a lens module. That is, if the camera D3 including the CCTV type or the camcorder type display is applied to the conventional camera D3, the camera 30 applied to the present invention can be regarded as the camera 30 applied to the endoscope have. Although not shown, a power line and a communication line are connected to the rear surface of the camera 30, which is powered by a control panel outside the Snout A, and the photographed data is transmitted to and received from the control unit.

The nitrogen gas injection tube 40 is installed on the tube inlet 11 side of the main housing 10 and is supplied to the inside. Although not shown, the nitrogen gas injection tube 40 compresses and supplies nitrogen stored in a nitrogen tank in a compressor.

Hereinafter, the operation of the camera mounting module E based on the organic coupling relationship of the components will be described.

First, nitrogen gas is supplied to the inner inlet 11 side of the main housing 10 by the nitrogen gas injection tube 40, and the supplied nitrogen gas is supplied to the outlet 13 along the inside of the tube body by the supply pressure And the gas which has reached the vicinity of the outlet 13 is compressed inside the tube body by the volume occupied by the camera 30 and the clogging along the area of the communication hole 21, And is discharged to the outlet 13 through a narrow area between the lens part 31 and the inclined part 12 of the first lens unit 12 and the exit 13.

Hereinafter, the means for mounting the camera mounting module E on the snout A will be described.

Fig. 2 shows the camera mounting module E of Fig. 1 mounted on the snout A. As shown, the means for mounting the camera mounting module E of Fig. 1 on the snout A is shown in Fig. The camera mounting module (E) may be mounted on the peripheral wall of the end portion of the nauta (A) through the tip of the camera mounting module (E). Although not shown, the camera mounting module E mounted on the snout A is mounted detachably from the peripheral wall of the snout A by using a flange or the like.

Hereinafter, the operation of the camera device of Snooth according to the present invention, which is achieved by the combination of the camera mounting module (E) and Snooth (A), will be described.

First, the camera mounting module (E) mounted on the snout (A) by the action of the camera mounting module (E) described above is supplied with nitrogen gas from the outside of the snout (A) The compressed gas is discharged through the outlet 13 of the camera mounting module E in the interior of the camera module A. [ At this time, the pressure of the discharged gas is set to be higher than the inner pressure of Snooth (A) by a predetermined difference. This ensures that the deposition gas inside the Snart (A) and the temperature elevated inside the Snart (A) do not flow into the interior of the camera mounting module (E).

Accordingly, the camera 30 mounted inside the camera mounting module E does not deposit the deposition gas inside the Snout A and is not deposited. At the same time, the temperature of the camera 30 does not flow into the Snout A, The temperature inside the mounting module (E) will not rise.

On the other hand, the camera mounting module E shown in FIG. 2 is shown largely to facilitate understanding of the principle, but is actually quite small. That is, about 1/10 of the duct D1 shown in FIG. Therefore, the amount of the gas flowing into the Snout (A) is significantly smaller than that in the prior art.

As described above, the specific configuration of the camera mounting module E included in the camera device of Snooth according to the present invention, the means for mounting the camera mounting module E on the SNUTT A, and the operation thereof are described The effects of the camera device of Snooth and the camera device of Snooth according to the present invention will be described based on the above description.

Hereinafter, the present invention will be described in detail with reference to the above-mentioned Snnut camera device.

The camera device of Snooth according to the present invention does not need a configuration for realizing a duct D1, a glass plate D2, and an air curtain applied to a conventional camera device of Snooth, and the consumption of nitrogen gas can be remarkably reduced .

Accordingly, it is an object of the present invention to provide a method and apparatus for depositing an evaporation material on a glass film, a frequent cleaning of a glass film, a considerable consumption of nitrogen, pressure and temperature drop in Snout (A) Poor plating of the strip C, and the like are completely solved.

Accordingly, since foreign substances are not deposited and thus the image quality is clean, there is no place where foreign materials can be buried, so that cleaning is unnecessary, and nitrogen gas is injected into a narrow space to be supplied in a compressed form. (A), which is operated in order to prepare for the increase of pressure and temperature inside Snooth (A) due to an excessive supply of nitrogen gas, is unnecessary. At the same time, You can get rid of worries about badness caused by change.

Further, the present invention has a simpler structure than the conventional one and is easy to apply to Snart (A), thereby remarkably improving the cost reduction due to manufacture and installation.

Hereinafter, a description will be given of a portion which is shown in the accompanying drawings but is not described.

(F) of FIG. 3 to FIG. 4 is an illumination light mounting module F. The illumination light mounting module F has the same principle as the camera mounting module E, An illumination lamp 50 is mounted instead of the camera 30 applied to the inside of the camera.

The light fixture mounting module F is applied to the snout A as a pair with the camera mount module E and is configured to illuminate a portion of the snout A to be photographed.

The light fixture mounting module F overlaps with the light fixture mounting module F, and its operation and effect are not described separately, so that it can be predicted.

It is understood that the light fixture mounting module F is included in the camera device of Snooth according to the present invention since it is an essential component in consideration of the internal conditions of Snout A.

Hereinafter, with reference to FIG. 5, the constructions capable of improving the functions in addition to the camera device of Snooth according to the present invention will be described.

5 is a view showing an embodiment in which the heat-resistant tube 60 and the illumination lamp 50 are added to the camera mounting module E included in the present invention. The attached drawing shows the enlarged detail of the tip of the main housing 10 of Fig.

The camera device of Snooth according to the present invention can prevent the internal temperature of the main housing 10 from rising due to the supply of nitrogen gas but prevents the internal temperature of the main housing 10 from rising even more positively, The camera 30 can be prevented from generating heat due to the temperature elevated inside the Snout A.

To this end, it is proposed that the heat-resistant tube 60 is inserted into the main housing 10 of the camera mounting module E included in the present invention. More specifically, the heat-resistant tubular body 60 is inserted into the main housing 10, and then the camera 30 is mounted inside the heat-resistant tubular body 60.

The heat-resistant tubular body 60 may be made of ceramic, heat-resistant metal, heat-resistant synthetic resin, or the like.

The heat-resistant tubular body 60 serves to prevent external heat from being transmitted to the interior, so that it is possible to positively prevent the camera 30 from generating heat due to the temperature of the inside of the snout A . This prevents malfunction of the camera 30 caused by heat and prevents damage, thereby enabling the camera to be used for a long time. The above-mentioned means also has an advantage of facilitating the manufacture of the camera mounting module (E).

On the other hand, when the heat-resistant tubular body 60 is not used, the main housing 10 itself can be applied to the same material as the heat-resistant tubular body 60 to prevent the camera 30 from generating heat.

In addition, the camera mounting module E included in the present invention proposes to incorporate the illumination light 50 into the camera mounting module E without separating them separately.

In order to achieve the above object, the present invention comprises a housing 71 having a bowl-shaped mounting space as shown in the accompanying drawings, a transparent circular plate 72 covering the tip of the opening of the housing 71, A mounting plate 73 having a plurality of communication holes 731 formed along the outer circumference of the housing 71 and a cover 74 which is fastened to the mounting plate 73 and is capable of binding the housing 71 and the transparent plate 72 A camera 76 is installed at the center of the board 75 by mounting a board 75 inside the housing 71 of the case 70 and the camera 76 is mounted on the board 75, It is proposed to provide a plurality of illumination lights 50 around the outer periphery.

The illumination lamp 50 is proposed to be implemented by the illumination light 50 by mounting the LED 77 and the red cover 78 at the tip of the LED 77 as shown in the figure.

This eliminates the need for a separate illumination light mounting module F so that the cost can be further reduced and it is no longer necessary to align the light illumination mounting module F with the camera mounting module E.

Meanwhile, the case 70 may be made of the same material as the heat-resistant tube 60 as described above. In this way, the heat generation of the camera 30 can be more positively prevented.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. And changes will be possible.
