Description

Semi-continuous system for the manufacture of panels.

Object of the invention

The present invention lies in a system of manufacture of panels, and more specifically, of composite panels by two profiled metal sheets and by an intermediate layer of solidified foam.

Background of the invention

Currently, the manufacturing systems of this Type of panels are classified in continuous manufacturing or discontinuous. Both systems have their advantages and inconvenience

The system in continuous, allows to vary the sheet metal to be used without stopping production, being a Perfect system for large panel productions, not However, it is not a good method for manufacturing a few meters, since the previous time dedicated to the preparation of the process implies an added cost in the final value of the product that the customer It can hardly absorb.

These manufacturing systems have shape generalized of a series of zones or stations, namely: - a sheet feed area, - profiling areas, - a foaming zone, - a foam curing zone, - a saw or cutting area and - a stacking area of said panels.

Currently, the sheet feed area It has a pair of upper unwinders and a pair of lower unwinders, for the supply of the plates that make up the upper and lower faces of the panels, circulating said plates respectively by a higher level and a lower level of the production line, which allows the subsequent application of the intermediate foam layer as it passes through the foaming zone.

The upper and lower unwinders are placed in such a way that, when a sheet coil is finished, the second coil can be started using a union of lock.

This system is ideal for productions of a high amount of panel meters, on the other hand, for production a few meters pose various problems, among which Highlight: the time spent preparing the line (se they must move the necessary coils to the unwinder corresponding, place them properly and prepare the machine), and very especially there is the problem of splicing the coils.

During production, it is frequent that make joints between coils, either because the order requires it or simply because the coil has ended, leading to this action a significant loss of sheet metal.

The current process to follow to join coils it consists of placing one sheet on top of the other and driving them attached to the profiling machine, but it is not an easy system and also an important part of sheet metal is lost.

Quantitatively, they are lost approximately about 10 meters of sheet metal by joint, whose loss of sheet makes orders of a few meters of panels represent an inconvenience important productive, since, even trying to adjust the price, manufacturing costs from the previous phase of preparation increase the final cost of the product in a way exaggerated

A major problem is the loss of material, because these 10 meters of sheet metal represent a generation of waste that the company wants to reduce, apart from the loss of aforementioned subject Another important drawback is the programming  of production, since, to be able to manufacture orders of few panel meters must stop production of large quantities to adapt the unwinders.

Despite the manufacture of orders of few panel meters is a necessity that the market needs to cover and panel manufacturers are not able to provision the customers who request a few meters of panel with a cost similar to orders of large number of meters.

Therefore, the technical problem to solve is the development of a manufacturing system that allows to supply a very small number of panels or even a panel at a price similar to that applied in the sale of thousands of meters, as well as get a satisfied customer and make a sale with Benefits.

Description of the invention

The panel manufacturing system of the invention, being of the type described above and that they have, for the continuous manufacture of panels, of: an area of unwind sheet feed, profiling areas of the  upper and lower plates, a foaming zone, an area of foam curing, a saw or cutting area and an area of stacked, it presents constructive particularities oriented to: allow its operation in a regime semi-continuous for the manufacture of orders with a Small number of units, reduce sheet metal waste originated, reduce material losses from the point of economic view, offer customers a panel at an optimal price, getting benefits in the sale of the product and the customer satisfaction for buying a product at a good price and improve the production system, reducing the handling of unnecessary sheet coils (which increases the safety of operators) and raising the production performance of the line.

The system of the invention allows to combine the continuous production system of the production line with a complementary feeding system, enabling the line to A semi-continuous production.

According to the invention, the system of manufacturing includes, in parallel to the production line, a complementary feeding system for unwinding, cutting and supply of sheet metal to the production line in an area prior to the profiling area of said line.

This complementary feeding system allows the manufacture of small orders working in a regime semicontinuously and alternatively with the power system and unwinding of the manufacturing system. This complementary system provides high versatility and adaptation to needs of production, since, if during continuous production of panels of a certain type it is necessary to manufacture a number reduced panels with color or thickness characteristics other than those that are being used on the line, it will only be it is necessary to suspend the system's own power and use the complementary feeding system, previously prepared from convenient mode, to supply the line with the precise plates to manufacture the number of panels needed and with the characteristics, color or thickness, required.

Therefore, this complementary system allows that the manufacturing system can be adapted specifically to the production of a few meters of panel, just stop the line of work in continuous and put the operation this complementary feeding system, complementary to that of The production line.

According to the invention said complementary system It includes, in parallel to the manufacturing system line of panels, at least: an unwinder, of alternative operation to the unwinder of the manufacturing system, for supply of the sheet metal necessary for operation semicontinuous of said panel manufacturing system, a shear of cutting for the elimination of those portions of sheet deteriorated that are usually productive losses and for the cutting of the unwound sheet according to the custom formats of the panels to be manufactured that are requested in orders of few meters, a depletion table, provided with a ramp articulated for the elimination of the cuts or losses that must be eliminated by presence of defect, and a transfer table or feed that moves the sheet formats previously cut and intended for the manufacture of panels, towards the line main, where they are profiled and used to manufacture panels, semi-continuous.

The mentioned transfer or feeding table It has a roller system for feeding the sheet metal formats cut to the main line of the system manufacturing.
