AN ASSEMBLY FOR PRODUCING A PARTICLE-LAMINATED METAL

SHEET

TECHNICAL FIELD

This invention generally relates to metal sheets that may be used as components of a static structure, such as a commercial building, but more particularly to an assembly for producing a particle-laminated metal sheet.

BACKGROUND OF THE INVENTION

Metal sheets forming parts of a static structure, such as a residential building, are exposed to weather elements adversely affecting their integrity. After a period of time, corrosive weather elements cause visible rusty surfaces indicating diminishing integrity. Galvanization or paint coating only provide a short term or temporary protection for the exposed surfaces of metal sheets, especially in structures being subjected to the forces of a windy environment and to the degrading effect of the ultraviolet light and intense heat generated by the sun, among others.

SUMMARY OF THE INVENTION

In view of the foregoing, it is one object of this invention to provide an assembly for producing a particle-laminated metal sheet which gives a better protection against quality-degrading weather elements. Particles, such as, particulate stone, sands, granulated earth materials and other desirable fine building-grade items will block the adverse effect of the ultraviolet light and intense heat from the sun and pounding force from the wind by serving as an insulating cover or coat.

Another object of this invention is to provide an assembly for producing particle-laminated metal sheet in its long span form. A long span building component, such as, a roof or wall metal sheet, will be easy to install as overlapping connections in segmented elements are consequently eliminated and thereby totally preventing rain water leaks from a heavy downpour during stormy weather condition especially when the metal sheet is used as roofing material.

Still, another object of this invention for an assembly for producing particle-laminated metal sheet is to provide a manufacturing plant that will eliminate the use of lifting equipment which increases operating energy cost and reduce manpower complements.

Other objects and advantages of the present invention for an assembly for producing particulate-laminated metal sheet will be fully understood and readily appreciated after reading the following detailed description made in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

Referring now to the drawings, there is shown in Fig.1 the assembly for producing particle-laminated metal sheet being designated by reference numeral 10, and generally comprising a series of working components consisting of a feeding table 11 , a base glue application unit 12, a

broadcasting table 13 adapted to disperse or broadcast particles of sand or particle-transformed stone or other desirable building grade fine earth materials, an air blower table 14, an oven or drier table 16, a top surface adhesive compound application table 17, another or drier oven table 16, a transfer table 18, a receiving table 19, a final oven or drier table 16, and a receiving end table 20 for a particle-laminated metal sheet constituting the final product being generated by the assembly 10.

As shown by the same drawing in Fig.1 , a span of metal sheet from a metal coil is cut according to predetermined length specified in a building plan or purchase order. The metal sheet, usually in a long span form as preferred by builders or contractors, is fed or laid on the feeding table 11. As the metal sheet is to be moved or conveyed from the feeding table 11 to the end receiving table 20, a material conveying means is provided for the tables. The material conveying means may be a belt and roller conveyor, or a chain and roller conveyor, or any equivalent model of conveyor. From the feeding table 11 , the metal sheet is conveyed to the base glue application unit 12 which will coat its upper or top surface with a film or lamina of glue or adhesive compound. The glue coated metal sheet is conveyed to the broadcasting table 13 where particulate materials are thoroughly broadcasted thereon in accordance with a predetermined amount, and to the air blower table 14 which will remove the excess or loose particles or particulate materials. The air blower table 14 is defined or characterized by a plurality of air blower tubes being spacedly provided over the table. Said air blower tubes emanate from an air pressure pump or compressor. To facilitate the hardening or drying process of the adhesive compound adhering to the particles or particulate materials, the metal sheet is conveyed through the oven or drier table 16 which generate heat from electric coils. After being conveyed through the oven table 16, the metal sheet moves through a top surface glue application table 17 which will coat its surfaces or layer of particles or particulate materials with a final film or lamina of glue or adhesive compound. From the top surface glue application table 17, the metal sheet is conveyed through another oven table for drying and to a transfer table 18. As shown in Fig.2, the transfer table 18 can be tilted through its pivot point by a hydraulic-powered push arm 21 being provided under its lower portion as a tilting means. The metal sheet is subsequently moved from the transfer table 18 to the receiving end table 19. The metal sheet is conveyed to an ultimate drying process in the final oven table 16, and finally moved or conveyed to a receiving end table 20 for quality inspection and retrieval.

While the invention for an assembly for producing a particle-laminated metal sheet has been disclosed in connection with the preferred embodiment shown and described in detail, various modifications, innovations and improvements thereon will become readily apparent to persons considered as skilled in the art. Accordingly, the spirit and scope of the present invention is not limited by the foregoing preferred embodiment but is to be understood in the broadest sense allowable by law.
