Description

DESCRIPTION

Robot cell, specially designed for cutting, milling and polishing pieces of natural stone and the like.

OBJECT OF THE INVENTION 5

The present invention, as expressed in the statement of this specification, refers to a cell with an anthropomorphic industrial robot, specially designed for cutting, milling and polishing boards of natural stone and the like, intended and milling, cutting, polish, engrave and carve blocks or boards of the referred materials.

BACKGROUND OF THE INVENTION

At present, the cutting or milling of pieces of stone and the like is done, mostly, by bridge or fixed head cutting machines equipped with a cutting head with diamond blade. In recent years, due to the demand for finished products that imply the need to make inclined or miter cuts, according to what is called colloquially in the sector, the fact that the cutters have the necessary equipment to be able to be able to start Perform this job. These machines, developed and evolved in terms of design and performance since the 70s, today have basically two limitations in terms of solving this so-called mitering process: 20

- Machines that have a tiltable head manually. Most of the machines built since 1990 are usually equipped with this system. They have the disadvantage that it requires the intervention of the machine operator to tilt the head, align the pieces to be cut and then return the head to its vertical position again. This is slow and 25 therefore expensive. In addition, the alignment of the pieces to be cut is problematic in that great skill of the operator is required.

-More modern machines that are usually equipped with CNC. Since 2000, machines with the head tilt system began to be seen automatically, although the cost of machines of this type is usually so high that it makes them inaccessible to most companies in the sector

The anthropomorphic industrial robot, as an active part in industrial processes, already has about four decades of history. 35

Processes such as the manipulation of castings, welding of car parts and their painting, or the loading and unloading of CNC or plastic injection machines, would now be competitively unfeasible without the use of robots for it.

 40

Although the automotive sector was initially the promoter and cause of the great development of robots, in the last 20 years the robot as a manufacturing system has been spreading to many industrial sectors.

In the sector of natural and related stone, the robot made its appearance in factories in the first 45 years of this century. Robots began to be installed for operation of manipulation and palletizing of parts in large factories.

Shortly after, integrators, especially Italians, developed robotic cells in principle for the manufacture of architectural elements where CNC machines with 4 or 50 axes were needed, such as sculptures, capitals, etc.

The morphology and limitations of scope and structural rigidity of anthropomorphic robots of normal sizes have meant that the cutting of boards has not been addressed to date by robots.

On the other hand, the high cost of the robots until a few years ago and the high cost of the 5 computer programs necessary for programming for a robot to operate as desired, made the use of these for the cutting and milling of natural stone unfeasible. . In recent years the maturity of these technologies has resulted in a clear decrease in the acquisition cost of these equipment and technologies.

DESCRIPTION OF THE INVENTION

The key idea of the invention is the morphology of the robotic cell, in which the industrial robot is placed in an inverted manner, suspended from a suitable structure for it.

This difference from what has been known so far has two key advantages for the success of the operation of the robotic cell:

- The robot is able to reach with the cutting head the pieces of sizes that are usually processed in the sector (3200 mm x 2000 mm) in practically any inclination of the required tool. twenty

- The robot includes among its components systems sensitive to dirty and humid environments such as servomotors and precision mechanical components. When the robot is placed in an inverted way, it is more protected from the dirt inherent in the stone cut.
