Abstract

The present invention relates to a steel mesh filter for a ship which is manufactured by making a plurality of layers of a metal mesh nets which have different meshes overlap, integrating each mesh net through wrinkle processing by pressing, rolling the mesh nets in the shape of a cylinder, and welding joining portions of the mesh nets. The present invention relates to a dispenser which applies epoxy resin along a straight welding line formed in a lengthwise direction on the outside of a filter body. More specifically, a discharge valve, connected to the epoxy pump, is installed on an object to be transferred of an LM guide which is arranged in a lengthwise direction of a table in accordance with a predetermined length of an upper side of an apparatus table. A location adjustment unit in a vertical direction using a pneumatic cylinder as a base is installed between a transfer stage and the discharge valve.

The dispenser smoothly guides single component type epoxy resin with a relatively high viscosity and enables a fixed amount of the single component type epoxy resin to be discharged. The present invention relates to the epoxy outside dispenser which is optimized for finishing processing of the welding line on the outside of the steel mesh filter for a ship.

Description

[0001] EPOXY OUTDOOR DISPENSER FOR WELDING FINISHING OF STEEL MESH FILTER FOR MARINE [0002] FIELD OF THE INVENTION [0003]

The present invention relates to a method for manufacturing a steel mesh for ships, which is manufactured by integrating each mesh network by wrinkle processing by pressing multiple layers of metal meshes having different mesh sizes and then welding the mesh portions of the mesh by rolling them into a cylindrical shape In the filter, an epoxy resin is applied along a linear weld line formed in the longitudinal direction on the outer surface of the filter body, and an automatic operation type pneumatic cylinder and a manually operated screw shaft And the discharge valve is also controlled as a pneumatic valve together with the pneumatic cylinder of the position adjusting unit to pressurize and discharge only the epoxy resin from the large capacity epoxy reservoir, The airless pump is used as an epoxy pump and connected to the discharge valve. , To a finished epoxy outside the dispenser which is optimized for operation of the filter body outer surface weld line of marine steel mesh filter through.

Generally, a steel mesh filter, which is generally used for ships, is formed by folding a plurality of metal meshes having different meshes (meshes) and pressing the metal meshes together so that the entire mesh of metal is corrugated The metal body is formed into a net shape, and then the metal body is wound in a cylindrical shape to weld a connecting portion where both side edges of the metal mesh are butted against each other, thereby manufacturing a filter body that provides a filtering base.

The filter body may be formed into a cylindrical shape having the same diameter along the longitudinal direction by cutting a plurality of metal net meshes integrated into a rectangular plate shape, cutting the mesh net into a trapezoidal shape, and gradually increasing its diameter toward one side A metal filter case of a cylindrical shape corresponding to the filter body is covered on the outer surface of the filter body and a metal filter cap is attached to both ends of the filter body Assembled and fixed, and the filter body and the filter casing are integrally connected to each other to complete the manufacture of the steel mesh filter.

Therefore, in the case of a steel mesh filter for ships, a linear weld line is inevitably generated along a portion where the metal mesh is stuck over the longitudinal direction of the cylindrical filter body providing the filtering base, It is very vulnerable to corrosion. Therefore, when the welding line of the filter body is left as it is, due to the characteristics of the marine filter exposed to a severe corrosive environment under relatively high temperature and pressure conditions, Lt; / RTI >

In order to solve the above problems, the epoxy resin is applied along the welding line of the filter body, and then the epoxy resin is thermally cured to finish the welding part. The finishing treatment state of the weld part varies from time to time according to the skill level and concentration of the operator, so that a certain quality can not be assured and the working speed is also very slow. Therefore, Korean Patent Publication No. 10-2012-0082677 An epoxy dispenser such as the one described is utilized.

However, the conventional epoxy dispenser has a cylindrical housing in which a small amount of epoxy resin is filled, an ejection nozzle of an epoxy resin connected to the lower end side of the housing, and a discharge nozzle connected to the upper end side of the housing, An injector including an air hose for injecting the air pressure required for discharge is provided on a stage capable of moving in the X-axis direction and the Y-axis direction. It is not only difficult to discharge a fixed amount of epoxy resin, There was a problem that was difficult to perform.

In other words, since a simple discharge method in which the epoxy resin filled in the housing of the injector is pneumatically pressed is applied, the discharge amount of the epoxy resin is relatively large depending on the remaining amount of the epoxy resin stored in the housing and the fluctuation of the air pressure The epoxy resin can not be applied uniformly along the welded portion of the outer surface of the filter body. Therefore, it is also preferable from the viewpoint of improving the pressure resistance performance and service life of the steel mesh filter It was the cause of the problem.

Particularly, since the amount of the epoxy resin which can be stored in the housing of the injector is very small, there is a problem that the processing of finishing the welded part of the filter body is frequently interrupted due to the frequent filling operation of the epoxy resin. The productivity of the steel mesh filter is greatly reduced. In addition, since only the screw jack is used for the up-down operation of the injector, there is a problem that the time for moving the injector to the start position and the end position of the work is unnecessarily delayed. If the lead width of the screw is increased, it is difficult to adjust the distance between the discharge nozzle and the welded portion to a required level in a more delicate manner.

The process of finishing the epoxy resin 23a to the welding line of the filter body 40 of the steel mesh filter for a ship using the dispenser 10 of the present invention having the above- The following is an explanation.

First, a filter body 40 of a steel mesh filter is mounted in the longitudinal direction on the upper surface of the apparatus table 1 using the filter support table 6, and the marking line indicated by the laser pointer 13 and the filter body The discharge nozzles 8 of the conveying table 4 located at the right end of the LM guide 2 in the drawing are moved to the driving cylinder 15 of the position adjusting unit 5 The discharge nozzle 8 is moved to the work start position together with the discharge valve 32 so that the discharge nozzle 8 is positioned on the right upper end of the welding line.

The epoxy pump 20 is operated so that the epoxy resin 23a stored in the epoxy reservoir 23 is pushed to the discharge nozzle 8 through the injection line 31 and the discharge valve 32 And the conveyance table 4 of the LM guide 2 is moved from the right end to the left end by operating the LM guide 2 so that the ejection nozzle 8 is moved horizontally The epoxy resin 23a discharged from the discharge nozzle 8 forms the epoxy line 41 along the welding line on the outer surface of the filter body 40. [

The limit sensor 14 provided at the corresponding position of the LM guide 2 is positioned on the transfer table 4 as soon as the finishing process by the epoxy resin 23a is completed along the welding line of the filter body 40 in the above- The supply of the epoxy resin 23a through the discharge nozzle 8 is stopped by detecting the sensor tip 19 of the position adjusting unit 5 and closing the discharge valve 32. Immediately thereafter, And the delivery nozzle 4 is moved again from the left end to the right end so that the discharge nozzle 8 is moved along with the discharge valve 32 to the original position To the position shown in FIG.

According to the present invention as described above, an airless pump in which only the epoxy resin 23a is sucked up by a pump motor 21 having air pressure as a driving source and is pressurized and discharged is used as the epoxy pump 20, and the epoxy pump 20, And the discharge valve 32 connected to the position adjusting unit 5 is also installed and controlled together with the drive cylinder 15 of the position adjusting unit 5 as a pneumatic valve and a manually operated screw shaft 18 It is possible to more quickly and accurately perform the finishing work on the outer side welding line of the filter body 40 of the steel mesh filter based on the quantitative discharge condition of the epoxy resin 23a.

In other words, by using the epoxy pump 20 as an airless pump, the one-component epoxy resin 23a having a relatively high viscosity is smoothly guided to the discharge valve 32 under a constant pressure condition, The ejection nozzles 8 and the welding nozzles 8 are moved up and down quickly by the driving cylinder 15 and the ejection nozzles 8 and the welding lines 8 The welding line finishing process of the filter body 40 can be performed more quickly and accurately than the conventional dispenser by applying the method of adjusting the gap between the filter body 40 and the filter body 40 more finely using the screw shaft 18.
