Description

Sealing Roller {SEALING-ROLLER}

The present invention relates to a sealing roller, and more particularly, to a sealing roller for applying a sealant to an aircraft part.

Generally, in the aircraft assembly stage, a sealant application process is performed in which a sealant is applied to the surface of the part to maintain airtightness between the aircraft parts. In this sealant application process, after the sealant is applied to the seal roller, the sealant is uniformly applied using a sealing roller.

The prior art for such a sealing roller is already known from " Korean Patent Laid-Open Publication No. 10-2008-0021854 (Rubber Roller Manufacturing Method, Mar. 3, 2008) ". The present invention is characterized in that a roller made of a rubber material is provided on a rotary shaft for applying a sealant.

However, since the conventional sealing roller needs to apply the sealant to the roller or the object to be coated separately, the working efficiency is lowered and the unnecessary force is required for the worker due to the small size. Accordingly, although an improved sealing roller is required, it has not been possible to provide a definite structure until recently.

FIG. 3 is a perspective view showing a sealant supply unit of a sealing roller according to the present embodiment, and FIG. 4 is an exploded perspective view showing a sealant supply unit of a sealing roller according to this embodiment.

3 and 4, the sealant supply unit 150 according to the present embodiment may include a supply main body 151 and a sealant diffusion portion 152. As shown in FIG.

First, the supply main body 151 forms a space in which the sealant is stored. The supply main body 151 may include a housing 151a, a storage tank 151b, and an operation trigger 151c.

The housing 151a forms an outer shape of the supply body 151 and is provided with an internal space in which the storage tank 151b is stored. The housing 151a may be formed in a cylindrical shape. A cover (c) capable of opening and closing the inside of the housing (151a) can be fastened to the upper end of the housing (151a), and a discharge passage through which the sealant is discharged from the housing (151a) is formed at the front end. One side of the housing 151a can be supported by the second support groove 133ba.

And the storage tank 151b stores the sealant. The storage tank 151b may be inserted into the housing 151a and may be integrally formed with the housing 151a as required. The storage tank 151b may be provided as a disposable one to be replaced when the inner sealant is exhausted, or may be provided to store the sealant repeatedly when the sealant is exhausted.

The operation trigger 151c may be mounted outside the housing 151a. The operation trigger 151c causes the sealant stored in the storage tank 151b to be discharged from the supply main body 151 to the outside through the discharge path of the housing 151a. Here, the operation trigger 151c may apply pressure to the storage tank 151b to discharge the sealant stored in the storage tank 151b, but the technique for discharging the sealant from the storage tank 151b is not limited.

On the other hand, the sealant diffusion portion 152 allows the sealant provided from the housing 151a to be uniformly provided in the width direction of the first roller 111. [ The sealant diffusion portion 152 may include a supply pipe 152a and a diffusion plate 152b.

The supply pipe 152a is disposed between the housing 151a and the diffusion plate 152b and forms a supply path through which the sealant discharged from the discharge path of the housing 151a is supplied to the diffusion plate 152b. Here, the supply pipe 152a may be detachably connected to the housing 151a and the diffusion plate 152b, respectively, for cleaning or the like. For example, the supply pipe 152a may include a pipe body 152aa, a housing fastening member 152ab, a diffusion plate fastening member 152ac, and a pipe support member 152ad.

First, the pipe body 152aa is provided in a cylindrical shape and can be supported by the first support groove 133aa. The pipe body 152aa may be formed in a substantially cylindrical shape and has a hollow portion interposed therebetween to allow the sealant to be supplied from the housing 151a to the diffusion plate 152b.

The housing fastening member 152ab may be disposed between the housing 151a and the pipe main body 152aa. Here, the housing fastening member 152ab allows the housing 151a and the pipe body 152aa to be detachably connected to each other.

The diffusion plate fastening member 152ac may be disposed between the pipe main body 152aa and the diffusion plate 152b. Here, the diffusion plate fastening member 152ac may be provided to press the front end of the pipe main body 152aa. The diffusion plate fastening member 152ac prevents the diffusion plate 152b from being detached from the pipe body 152aa when the diffusion plate 152b is inserted and connected to the front end of the pipe body 152aa, 152aa and the diffusion plate 152b can be separated from each other.

The pipe support member 152ad is provided outside the pipe body 152aa so that the pipe body 152aa that is seated and supported in the first support groove 133aa is fixed to the first support frame 133a. For example, the pipe support member 152ad may be provided in the form of a ring. Here, the pipe support members 152ad may be provided as a pair. At this time, the pair of support members press the pipe main body 152aa supported by the first support groove 133aa toward the first support frame 133a so that the pipe main body 152aa is supported by the first support frame 133a ). ≪ / RTI >

The upper end of the diffusion plate 152b is supported at the front end of the pipe body 152aa and the lower end of the diffusion plate 152b is adjacent to the first roller 111. [ The upper end of the diffuser plate 152b may be provided to correspond to the widthwise length of the pipe body 152aa so as to be insertable into the front end of the pipe body 152aa, In the width direction. The diffusion plate 152b allows the sealant provided from the pipe body 152aa to be uniformly provided to the surface of the first roller 111. [

More specifically, the diffusion plate 152b may include a first diffusion plate 152ba, a second diffusion plate 152bb, and a diffusion member 152bc.

Here, the first diffusion plate 152ba and the second diffusion plate 152bb may be provided in the same form. At this time, as the first diffusion plate 152ba forms a lower plate and the second diffusion plate 152bb forms an upper plate, a sealant flows between the first diffusion plate 152ba and the second diffusion plate 152bb So that a path can be formed.

The diffusion member 152bc is disposed between the first diffusion plate 152ba and the second diffusion plate 152bb. The diffusion member 152bc disperses the sealant supplied into the diffusion plate 152b so that the sealant is uniformly provided in the width direction of the first roller 111. [

For example, the diffusion member 152bc may be provided as a plurality of frames F1. Here, the plurality of frames F1 are dispersed so that one end is concentrated in the upper direction of the diffusion plate 152b and the other end corresponds to the lower end width length of the diffusion plate 152b. Accordingly, the plurality of frames F1 can uniformly disperse the sealant supplied into the diffusion plate 152b toward the upper surface of the first roller 111. [

The plurality of diffusion members 152bc may be integrally formed with the first diffusion plate 152ba or the second diffusion plate 152bb and the first diffusion plate 152ba and the second diffusion plate 152bb, As shown in Fig. The plurality of diffusion members 152bc are for explaining the present embodiment, and may be omitted from the sealing roller 100 as needed.

Hereinafter, the driving of the sealing roller according to the present embodiment will be described in detail with reference to the accompanying drawings. However, the detailed description of the above-described components will be omitted, and the same reference numerals will be used to describe them.

5 is a flowchart showing the driving of the sealing roller according to the present embodiment.

As shown in FIG. 5, the sealing roller 100 according to the present embodiment can be used in a sealant application process for maintaining airtightness between aircraft parts in an aircraft assembly stage.

However, in the following description, the application of the sealant to the aircraft part is described, but this is not intended to limit the object to be coated to the aircraft part.

First, the operator injects the sealant into the sealing roller 100 prior to assembly of the aircraft part, and causes the sealant to be applied to the aircraft part using the sealing roller 100 (S100). At this time, the operator can grasp the grip portion 132 with one hand and manipulate the operation trigger 151c with the other hand so that the sealant is applied to the surface of the aircraft portion. Here, the worker can more easily apply the sealant to the surface of the aircraft part by using the weight of the sealing roller 100 including the metal material.

On the other hand, as the operator operates the operation trigger 151c, the sealing roller 100 flows into the supply pipe 152a through the discharge passage of the housing 151a, the sealant stored in the storage tank 151b. The sealant introduced into the supply pipe 152a is supplied into the diffusion plate 152b. Here, the diffusion plate 152b allows the sealant supplied to the inside to be diffused therein by using the plurality of frames F1.

Thus, the diffused sealant is uniformly diffused in the width direction of the first roller 111 and supplied to the upper surface of the first roller 111 (S200). At this time, the operator transfers the sealing roller 100 and uniformly applies the sealant on the surface of the airplane part.

Here, the sealant provided on the upper surface of the first roller 111 is uniformly applied to the surface of the aircraft part in accordance with the rotation of the first roller 111. However, at this time, a plurality of grooves 111c are formed on the surface of the first roller 111. FIG. Thus, the sealant applied to the surface of the airplane part may be applied in a width corresponding to the width direction of the first roller 111, but may not be smoothly applied (S300). However, as the surface of the second roller 112 disposed at the back of the first roller 111 is formed flat, the sealing roller 100 is formed such that the operator can press the second roller 112 following the first roller 111 The sealant primarily applied to the surface of the aircraft part can be flattened by the second roller 112 (S400).

On the other hand, when the sealant application process is completed, the operator can proceed the cleaning process of the sealing roller 100. [ At this time, if the sealant remains in the sealant diffusing portion 152, the sealant may solidify in the sealant diffusing portion 152, which may cause problems in later use. Here, the operator can separate the sealant diffusion portion 152 from the supply main body 151 and separate each constituent element of the sealant diffusion portion 152 to carry out the cleaning process.

As described above, the sealing roller not only improves the work efficiency of the sealant application process, but also allows the sealant to be easily and uniformly applied only by the self weight of the sealing unit itself, thereby reducing the work difficulty of the worker.

One embodiment of the invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
