Abstract

Provided are an apparatus for manufacturing a textile grid with increased adhesion and a method thereof capable of integrating the textile grid with a concrete structure by increasing the adhesion of the textile grid when the concrete structure is built, repaired, or reinforced, increasing structural safety and durability of the concrete structure, increasing a working speed by coating a surface of the textile grid with an abrasive material powder that is a surface coating material in an automatic series of processes immediately after the textile grid is manufactured, and increasing coating performance by automatically inspecting and adjusting the amount of the coating material applied to the surface of the textile grid using a camera.

First claim

What is claimed is:

1. An apparatus for manufacturing a textile grid with increased adhesion for building, repairing, or reinforcing a concrete structure, the apparatus comprising:
a fabric yarn supplying unit that supplies textile grid fabric yarn in a form of a bundle of yam;
a weaving-knitting machine that forms a woven-knitted textile grid in a lattice form through a manner in which the fabric yarn is woven and knitted so that wefts and warps cross to be coupled to each other;
a resin impregnation tank that impregnates the woven-knitted textile grid with a resin to form a resin impregnated textile grid;
a coating chamber that comprises a first coating material spraying nozzle and a second coating material spraying nozzle installed in the coating chamber, configured for coating an abrasive material powder that is a surface coating material onto a surface of the resin impregnated textile grid and which forms a coated textile grid before the resin impregnated textile grid is cured;
a camera that is installed at a rear end of the coating chamber and captures a coating-image to inspect a coating state of the coated textile grid; and
a controlling device that adjusts a spraying amount of the surface coating material according to the coating-image captured by the camera,
wherein adhesion of the textile grid to a concrete structure is increased by the abrasive material powder that is the surface coating material.

2. The apparatus for manufacturing a textile grid with increased adhesion of claim 1 , wherein the coating chamber is formed as a closed space, and coating is performed using at least two coating material spraying nozzles comprising the first coating material spraying nozzle and the second coating material spraying nozzle to spray a coating material to both surfaces of the resin impregnated textile grid.

3. The apparatus for manufacturing a textile grid with increased adhesion of claim 2 , wherein the spraying amount of the coating material sprayed on the surface of the resin impregnated textile grid is determined by a sprayed coating material directly sprayed from the first coating material spraying nozzle and the second coating material spraying nozzle and a scattered coating material scattered in the coating chamber.

4. The apparatus for manufacturing a textile grid with increased adhesion of claim 1 , wherein the abrasive material powder that is the surface coating material comprises sand, silica sand, or alumina oxide powder.

5. The apparatus for manufacturing a textile grid with increased adhesion of claim 1 , further comprising a surface coating material supplying unit that supplies a coating material to the first coating material spraying nozzle and the second coating material spraying nozzle in the coating chamber and adjusts the spraying amount of the coating material under control of the controlling device.

6. The apparatus for manufacturing a textile grid with increased adhesion of claim 5 , further comprising:
a resin curing chamber that allows the coated textile grid formed in the coating chamber to be cured to form a cured textile grid; and
a winding unit that winds the cured textile grid of the resin curing chamber.

7. The apparatus for manufacturing a textile grid with increased adhesion of claim 1 , wherein the controlling device comprises:
a coating-image collecting part that collects a coating image, which is an image of a coated coating material, captured by the camera;
a data processing part that processes data to analyze the coating image collected by the coating-image collecting part;
a coating state determining part that determines whether a coating state of a surface of the coated textile grid is appropriate based on the data processed by the data processing part; and
a coating material spray adjusting part that adjusts the spraying amount of the coating material supplied to the first coating material spraying nozzle and the second coating material spraying nozzle in the coating chamber when a state of the coating material applied on the surface of the coated textile grid is not appropriate as a result determined by the coating state determining part.

8. The apparatus for manufacturing a textile grid with increased adhesion of claim 7 , wherein the controlling device further comprises a pull-out motor speed adjusting part that adjusts a speed of a pull-out motor installed in front of a winding unit to adjust a coating amount of the coating material applied to the surface of the resin impregnated textile grid.
