Description

[0001] Reinforced panel forming apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforced panel forming apparatus, and more particularly, to a reinforced panel forming apparatus in which reinforced fabrics are sequentially and continuously longitudinally moved by hot compression molding and cold compression molding, To a reinforced panel forming apparatus.

In recent years, reinforced panels, such as carbon fiber and glass fiber, have been pressed and formed. They are 5 times lighter in weight than steel plates, 10 times more tensile strength than the steel plate, and have a beautiful appearance due to a unique pattern exposed on the surface. And the usability thereof is gradually increasing.

However, although the reinforcing fabric constituting the reinforcing panel has a high tensile strength due to its characteristics, when the stress is higher than the yielding point, the reinforcing fabric easily breaks, so that it is practically difficult to apply to the outer wall of a structure requiring high strength.

In order to solve this problem, in the related art, a reinforcing layer is formed on the surface of the reinforcing pad by a composite resin or the like to complement the brittle strength of the reinforcing pad laminated by the reinforcing layer. However, It is necessary to increase the cost of production due to manufacturing.

On the other hand, in a conventional method for forming a reinforcing panel by hot pressing a reinforcing fabric, a plurality of reinforcing fabrics cut by a worker are stacked and aligned, and then the aligned reinforcing fabric is put in a hot pressing device, The panel is molded.

That is, the worker must manually align the reinforced fabrics cut by hand in a laminated manner and insert them into the hot press apparatus, so that the productivity is remarkably reduced and the additional cost for fabrication is excessively high.

To solve these problems, the present inventors have proposed a reinforcing panel forming method and apparatus for hot-pressing laminated reinforcing fabrics through a hot pressing roller through Korean Patent Application No. 2015-0159577.

Continuous feeding and hot compression of the reinforcing fabric can be achieved by hot pressing while transferring the reinforcing fabric through the hot pressing roller in the longitudinal direction, and consequently, continuous production of reinforcing panel through hot pressing of the reinforcing fabric is possible.

As a result of directly hot-pressing the reinforcing fabrics through the hot-pressing roller, the fabric pattern of the hot-pressed portion by the hot-pressing roller is pushed to the outlet side and is disturbed, Problems caused by defects have been pointed out.

That is, in the present invention, the width of the hot press belt 132 for hot-pressing the laminated reinforcing fabric 10 moving in the longitudinal direction through the temperature measuring sensors 141 constituting the section temperature measuring module 140 The control unit of the electrothermal heater adjusts the temperature of the surface heating member 133a individually in accordance with the temperature of the zone of the measured hot press belt 132 so that the hot press belt 132 is moved in the width direction So that the optimum temperature for the hot melt adhesion of the laminated reinforcing fabric without any deviation is maintained uniformly.

That is, as shown in FIG. 6, when the temperature of both the left and right sides of the hot press belt passing through the first section and moving to the second section is measured by each of the temperature measuring sensors of the temperature measuring module disposed in the first section, The electrothermal heaters arranged in the second section increase the temperature of the surface heating members disposed on both the left and right sides so that the hot compression belt maintains the optimum temperature for the hot pressing of the laminated reinforcing fabrics in the left and right direction.

Thus, the hot-pressing module controls the temperature of the hot-press belt in the left and right directions to thermally press the reinforcing fabrics moving in the longitudinal direction along the hot-forming furnace to an optimum temperature according to the hot- These reinforcing fabrics are heat-welded and discharged.

On the other hand, on the surface of the hot-press belt 132 of each of the hot-pressing modules 130 obtained by hot-fusing the laminated reinforcing fabric 10, sludge generated in the hot- pressing process of the reinforcing fabric 10 sticks to the surface Is inevitably generated.

The sludge adhering to the surface of the hot press belt 132 may cause a phenomenon that the sludge adhering to the surface of the hot press belt 132 is adhered to the surface of the hot press fabric 10 during the hot press process of the subsequent reinforcement fabric 10, Such sludge may also cause poor appearance of the final molded reinforced panel 20. [
